A buckle for a belt that suppresses clothes from sliding includes: a buckle body configured to be fixed to one end of the belt; a belt locking unit provided on the buckle body, the belt locking unit being configured to lock the belt to the buckle body; and an engaging unit provided on the buckle body or the belt locking unit, the engaging unit being configured to engage with a part of the clothes so as to support the part of the clothes from a lower side thereof.

TECHNICAL FIELD
The present invention relates to a buckle, a belt, and a belt part.

BACKGROUND ART
When clothes such as trousers (or pants) are worn, in order to suppress the clothes from shifting (or sliding down), a belt configured by a strip-shaped cloth or leather and a buckle is generally used well.
However, in a case where a belt is worn while trousers are worn but a waist size of clothes such as the trousers does not match a body shape of a wearer, a front opening portion of the trousers may particularly slide down with respect to the belt due to slackening of the clothes with respect to the body shape. Such sliding down looks bad and is not preferable in view of fashion. Further, a buckle of the belt is often made of metal. Therefore, when the buckle made of metal comes into contact with skin of a wearer due to the sliding down described above, the wearer may develop a metallic allergy.
JP2006-183177A discloses a trouser sliding-down preventing tool as a tool for suppressing clothes from sliding down as described above. The trousers sliding-down preventing tool is configured to tie trousers to an outer garment by sandwiching back fabric of the outer garment and locking back fabric of a waist portion of the trousers.

SUMMARY OF INVENTION
However, the trousers sliding-down preventing tool as disclosed in JP2006-183177A must be prepared separately from a belt. Further, it is necessary to sandwich the back fabric of the outer garment, whereby detachment is troublesome. Further, in a case where an outer garment is not housed in trousers, wrinkles of a sandwiched portion of the outer garment are conspicuous, and the outer garment is tied to the trousers. Therefore, it cannot be used.
It is an object of the present invention to provide a technique capable of easily preventing clothes such as trousers from sliding down without utilizing an outer garment.
The present invention is provided a buckle for a belt that suppresses clothes from sliding. The buckle includes: a buckle body configured to be fixed to one end of the belt; a belt locking unit provided on the buckle body, the belt locking unit being configured to lock the belt to the buckle body; and an engaging unit provided on the buckle body or the belt locking unit, the engaging unit being configured to engage with a part of the clothes so as to support the part of the clothes from a lower side thereof.

DESCRIPTION OF EMBODIMENTS
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

-First Embodiment-
FIG. 1 is a view for explaining a buckle 10 according to a first embodiment. The buckle 10 according to the present embodiment is a buckle for a belt, which suppresses clothes from sliding. The buckle 10 is configured by a buckle body (or a frame) 2, a belt locking unit (or a prong) 3, and an engaging unit 4. One end of a belt 1 made of a strip-shaped cloth or leather is fixed to the buckle body 2. The engaging unit 4 is provided in the belt locking unit 3.
The buckle body 2 is a metallic member that is formed in a substantially annular shape. The buckle body 2 includes a shaft (or a side) 2a that constitutes one end thereof. The one end of the belt 1 is fixed to the shaft 2a, and a ring-shaped base 3a formed at one end of the belt locking unit 3 is rotatably supported. Further, a belt inserting unit 5 is formed in an inner space of the buckle body 2 formed in a substantially annular shape. The other end of the belt 1 passes through the belt inserting unit 5 when the belt 1 is worn. It is to be noted that the shape of the buckle body 2 is not limited to a rectangular shape as illustrated in FIG. 1, and may be a circular shape, an elliptical shape, or a polygonal shape other than that illustrated in FIG. 1. It is not limited particularly.
The belt locking unit 3 is a pin-shaped member (or a prong) rotatably provided on the buckle body 2. The belt locking unit 3 locks the belt 1 to the buckle body 2 by inserting an end portion (that is, a tip) of an opposite side of the base 3a into a locking hole 1a (see FIG. 3) of the belt 1 that passes through the belt inserting unit 5.
The engaging unit 4 is a part of the belt locking unit 3. The engaging unit 4 is configured to engage with a part of clothes when the clothes are worn to support the part of the clothes from a lower side thereof. Details of the engaging unit 4 will be described later with reference to FIG. 2.
Here, problems to be solved by the present invention will be described.
FIG. 17 is a view for explaining problems to be solved by the present invention. When clothes (in particular, bottoms) such as trousers (or pants) including jeans and slacks are worn, it is generally to fasten a belt in order to suppress the clothes from sliding down (or slipping down). However, in a case where the belt is fastened while the trousers are worn and a waist size of the trousers does not match a body shape of a wearer, in particular, in a case where the waist size of the trousers is larger than the waist size of the wearer, a phenomenon in which the trousers, in particular, an upper end portion of a front surface thereof (that is, a front opening portion or a fly portion) slides down with respect to the belt occurs due to looseness of the clothes with respect to the body shape.
As illustrated in FIG. 17, the appearance of the front opening portion of the trousers that slides down with respect to the belt gives a viewer an untidy impression. Therefore, it looks bad and is not preferable in view of fashion. Further, when a buckle made of metal touches skin of the wearer for a long time due to sliding down of the trousers, there is a risk that metallic allergy is developed to the wearer. For this reason, it is not preferable from a viewpoint of health and hygiene. It is an object of the present invention to easily prevent the phenomenon of sliding down of the trousers, which causes such problems, without affecting the appearance and without imposing a work burden on the wearer. Hereinafter, details of the engaging unit 4 according to the present embodiment, which is one example of a concrete configuration for solving the problems, will be described.
FIG. 2 is a view illustrating the buckle 10 according to the present embodiment. FIG. 2(a) is a front view of the buckle 10 when viewed from a front face thereof. FIG. 2(b) is a top view of the buckle 10 while trousers are worn (while the belt is worn) when viewed from the above (a direction of an arrow illustrated in FIG. 1). Further, an up down arrow illustrated in FIG. 2(a) indicates a vertical direction corresponding to a direction of gravity, and a direction indicated by a thick arrow (or a hollow or white arrow) illustrated in FIG. 2(b) indicates a user's body side (that is, a trouser side) in a case where the buckle 10 is used at the time of wearing the trousers. It is to be noted that hereinafter, the "trouser side" indicates a direction pointed out by the thick arrow, a "front side" indicates a direction opposite to the direction pointed out by the thick arrow (front when viewed from a wearer thereof), an "upper side" and a "lower side" indicate a vertical direction of the direction of gravity of the buckle 10 at the time of wearing the trousers, and a "lateral direction" indicates a horizontal direction orthogonal to the vertical direction.
As illustrated in FIG. 2(a), in the belt locking unit 3 according to the present embodiment, the base 3a thereof is rotatably supported at a substantially central portion of the shaft 2a in the buckle body 2 in the vertical direction, and has a rod shape (or a pin shape) substantially linear in the lateral direction in a front view. However, the position in the vertical direction where the base 3a is supported by the shaft 2a is not limited to the substantially central portion of the shaft 2a, and may be appropriately set from the viewpoint of particularly improving easiness of a work for causing a part of trousers (will be described later) to engage with the engaging unit 4.
The engaging unit 4 according to the present embodiment is a part of the belt locking unit 3, and is configured so that the part of the trousers engages with a concave shaped portion 6 of the belt locking unit 3. The concave shaped portion 6 is formed at the front side by being curved so as to have a convex shape toward the trouser side. The part of the trousers mentioned herein is a button (a so-called top button) of the trousers that is particularly located in the vicinity of an upper end of the front surface (that is, in the vicinity of the upper end of a front opening portion or a fly portion). It is to be noted that the button mentioned herein also includes a connecting unit between the button and trouser fabric such as a sewing thread or a rigid, which connects the button to the trouser fabric.
It is more preferable that the engaging unit 4 not only protrudes toward the trouser side, but also is configured so as to form a space 7 with a predetermined width between a shaft of the buckle body 2 at an upper side (that is, a shaft 2b) and the concave shaped portion 6 as illustrated in FIG. 2(b). When the belt is to be fastened at the time of wearing the trousers, the engaging unit 4 configured in this manner hooks the button that is introduced to an inner diameter side of the buckle body 2 through the space 7 formed between the buckle body 2 and the engaging unit 4. This makes it possible to support the button from a lower side thereof. A state where a part of trousers engages with the concave shaped portion 6 located at a front surface of the trousers will be described with reference to FIG. 3.
FIG. 3 is a view for explaining a state where the engaging unit 4 engages with the button when the trousers are worn.
FIG. 3(a) is a view for explaining a state where the button engages with the engaging unit 4 when the belt is fastened while the trousers are worn. FIG. 3(a) illustrates a state where a lower side of a button 8 is hooked on the engaging unit 4, which is obtained by moving the belt locking unit 3 while holding the buckle body 2, for example, by a wearer in a state where the wearer passes the other end side of the belt 1 through the belt inserting unit 5 of the buckle 10 and further inserts a tip of the belt locking unit 3 into the locking hole 1a. Namely, FIG. 3(a) illustrates a view of a state where the button 8 is supported from the lower side thereof by the belt locking unit 3 having the engaging unit 4 in the process of fastening the belt 1 while the trousers are worn when viewed from the front face of the buckle 10.
FIG. 3(b) is a view of the buckle 10 illustrated in FIG. 3(a) when viewed from under the buckle 10 (see the direction of the arrow illustrated in FIG. 3(b)). As illustrated in FIG. 3(b), in the present embodiment, it can be seen that the button 8 is supported from the lower side thereof by the belt locking unit 3 by particularly hooking a connecting unit 8a of the button 8 on the engaging unit 4. As a result, even though the trousers try to slide down, the button 8 that is the part of the trousers is supported from the lower side thereof by the buckle 10. Therefore, it is possible to suppress the trousers from sliding down with respect to the buckle 10. It is to be noted that since the belt locking unit 3 according to the present embodiment is configured so as to form the space 7 between the buckle body 2 and the engaging unit 4, the button 8 is hardly in contact with the shaft 2b of the buckle body 2 when the button 8 is caused to engage with the engaging unit 4. Namely, by configuring the buckle 10 so as to have the space 7, the button 8 hardly comes in contact with the buckle body 2. Therefore, it is possible to cause the button 8 to engage with the engaging unit 4 easily.
FIG. 3(c) is a view illustrating a state where the belt 1 is completely fastened while the trousers are worn. As illustrated in FIG. 3(c), by fastening the belt 1 as usual after the button 8 is caused to engage with the engaging unit 4 of the buckle 10, the button 8 and the engaging unit 4 are accommodated between the belt 1 and the trousers, and become invisible from the front face. Namely, the buckle 10 according to the present embodiment can exhibit a function of preventing the trousers from sliding down without affecting the appearance of a waist circumference of the wearer at the time of wearing the trousers. It is to be noted that shapes of the belt locking unit 3 according to the present embodiment and the engaging unit 4 are not limited to those illustrated in FIGS. 2 and 3, and may include various shapes so long as the button 8 can be supported from the lower side thereof by engaging with the engaging unit 4.
FIG. 4 is a view for explaining a shape of the buckle 10 according to the present embodiment, in particular, details of the space 7 formed by the engaging unit 4. FIGS. 4(a) to 4(c) illustrate views the buckle 10 at the time of wearing the trousers when viewed from the upper side thereof. Further, thick arrows respectively illustrated at left sides of FIGS. 4(a) to 4(c) indicate the trouser side at the time of wearing the belt.
As illustrated in FIGS. 4(a) and 4(b), so long as the engaging unit 4 is curved or bent so as to have the convex shape toward the trouser side, the shape of the concave shaped portion 6 formed at the front side is not limited to an arc shape as illustrated in FIG. 2(b), and may appropriately be set to any shape such as a curved line or a straight line as illustrated in FIGS. 4(a) and 4(b).
Further, as illustrated in FIG. 4(c), a shape of the shaft 2b at the upper side of the buckle body 2, in particular, at the trouser side is not necessarily a linear shape, and may have a curved shape that protrudes toward the front side.
Namely, the shape of the space 7 formed between the concave shaped portion 6 and the shaft 2b when the buckle 10 according to the present embodiment is viewed from the above may be set appropriately. However, the space 7 is formed mainly for the purpose of reducing a chance of a contact between the button 8 and the buckle body 2 while the belt is worn and facilitating the work to cause the button 8 to engage with the engaging unit 4. Therefore, it is preferable that the space 7 is formed so as to have a size to the extent that dimension when the button 8 provided in the trousers to be worn is viewed from the vertical direction (for example, see FIG. 3(b)) can be accommodated.
For example, in a case where a length of the space 7 in the lateral direction orthogonal to the vertical direction at the time of wearing trousers is A and a length thereof in a direction parallel to a trouser side direction is B, the space 7 according to the present embodiment may be formed so that the length A is larger than 1.7 cm and the length B is larger than 1.5 mm in consideration of commercially available jeans provided with a top button whose diameter is 1.7 cm and whose thickness is 1.5 mm. In other words, the space 7 may be formed so as to include at least an area of a rectangular shape formed by a side of 1.7 cm in the lateral direction and a side of 1.5 mm in the trouser side direction. By forming such a space 7 in the buckle 10, it is possible to further improve easiness of the work for causing the button 8 to engage with the engaging unit 4 when the wearer is wearing the belt. It is to be noted that the above area may be set appropriately from the viewpoint of easiness of engagement in accordance with a shape and a size of a side surface of the button 8 as an engagement target.
As described above, according to the buckle 10 of the first embodiment, the buckle 10 for the belt 1 that suppresses clothes from sliding is configured so as to include: the buckle body 2 configured to be fixed to one end of the belt 1; the belt locking unit 3 (the belt locking unit) provided on the buckle body 2, the belt locking unit 3 being configured to lock the belt 1 to the buckle body 2; and the engaging unit 4 provided on the buckle body 2 or the belt locking unit 3, the engaging unit 4 being configured to engage with the part of the clothes so as to support the part of the clothes from the lower side thereof. As a result, by applying the buckle 10 to a conventional belt, it is possible to support the part of the clothes such as the trousers from the lower side thereof. Therefore, it is possible to easily prevent the clothes such as the trousers from sliding down.
Further, according to the buckle 10 of the first embodiment, the part of the clothes is the button 8 provided at the upper end of the front surface of the trousers. Further, the belt locking unit 3 is the pin-shaped member to lock the belt 1 by inserting the belt locking unit 3 into the locking hole 1a of the belt 1. The engaging unit 4 is the part of the belt locking unit 3, and is configured so that the button 8 engages with the concave shaped portion 6 (a first concave shaped portion) formed at the opposite side (the front side) to the trouser side by being curved so as to have the convex shape toward the trouser side while the trousers are worn. As a result, since the engaging unit 4 is configured so as to be located closer to the body side of the wearer, it is possible to facilitate the work for causing the button 8 as the part of the clothes to engage with the engaging unit 4 at the time of wearing the belt. Further, since the engaging unit 4 in the buckle 10, which supports the button 8, is formed in the belt locking unit 3, it is possible to eliminate an influence on the appearance of the trousers by fastening the belt while the trousers are worn.
Further, the buckle 10 according to the first embodiment has the space 7 with the predetermined width between the buckle body 2 and the concave shaped portion 6 when viewed from the above while the trousers are worn. As a result, when the wearer causes the button 8 to engage with the engaging unit 4 at the time of wearing the belt, the button 8 and the buckle body 2 hardly come into contact with each other. Therefore, it is possible to further improve the easiness of the work for causing the button 8 to engage with the engaging unit 4.

-Second Embodiment-
A buckle 20 according to a second embodiment of the present invention will be described. The buckle 20 according to the present embodiment is different from that according to the first embodiment in a shape of the belt locking unit 3. Hereinafter, the differences will mainly be described with reference to the drawings. Further, the same reference numeral is assigned to each of the similar components to those of the first embodiment described above, and their explanation is omitted.
FIG. 5 is a view for explaining the buckle 20 according to the second embodiment. FIG. 5(a) is a front view of the buckle 20 when viewed from the front thereof. FIG. 5(b) is a top view of the buckle 20 while a belt is worn when viewed from the above thereof. Further, an up down arrow illustrated in FIG. 10(a) indicates a vertical direction corresponding to a direction of gravity, and a direction indicated by a dotted arrow illustrated in FIG. 10(b) indicates a trouser side in a case where the buckle 20 is used at the time of wearing trousers.
As illustrated in FIG. 5, an engaging unit 24 included in the buckle 20 is a part of a belt locking unit 3, and is configured so that a part of the trousers (that is, a button 8) engages with a concave shaped portion 26. The concave shaped portion 26 is formed at an upper side thereof by being curved so as to have a convex shape toward a lower side thereof. According to such a configuration, by particularly hanging a connecting unit 8a of the button 8 on the engaging unit 24, it is possible to support the button 8 from a lower side thereof by the belt locking unit 3. Further, by particularly hang the connecting unit 8a on the concave shaped portion 26 that protrudes toward the lower side, it is possible to suppress the buckle 20 from being displaced in a lateral direction with respect to the trousers more suitably. It is to be noted that a shape of the engaging unit 24 is not limited to the shape illustrated in FIG. 5, and may include various shapes so long as the button 8 can be supported from the lower side thereof by engaging with the engaging unit 24.
FIG. 6 is a view for explaining another example of the shape of the buckle 20 according to the present embodiment. FIGS. 6(a) to 6(d) illustrate front views of the buckle 20 at the time of wearing the belt. Further, up down arrows respectively illustrated at left sides of FIGS. 6(a) to 6(d) indicate the vertical direction corresponding to the direction of gravity at the time of wearing the belt.
As illustrated in FIGS. 6(a) and 6(b), so long as the engaging unit 24 is curved or bent so as to have a convex shape toward the lower side, the shape of the concave shaped portion 26 formed at the upper side is not limited to a curved line as illustrated in FIG. 5(a), and may appropriately be set to any shape such as a triangular shape or a linear shape.
Further, as illustrated in FIG. 6(c), a shape of a shaft 2b provided at an upper side of a buckle body 2, in particular, a shape of a lower side thereof (the engaging unit 24 side) is not necessarily a linear shape, and may have a curved shape that protrudes upward. In other words, the lower side of the shaft 2b of the buckle body 2 (the engaging unit 24 side) may have a concave shaped portion that is recessed upward.
Further, as illustrated in FIG. 6(d), a base 3a of the belt locking unit 3 is not necessarily provided at a substantially central portion of a shaft 2a of the buckle body 2 in the vertical direction, and may be provided below the substantially central portion. In a case where an end portion (or a tip) of the belt locking unit 3 at an opposite side to the base 3a is located at a substantially center of the buckle body 2 in the vertical direction, the engaging unit 24 may be configured as a difference in level provided between the base 3a and the tip of the belt locking unit 3. In this case, as illustrated in FIG. 6(d), a portion in the difference in level formed between the base 3a and the tip of the belt locking unit 3, whose height in the vertical direction substantially coincides with a position of the base 3a, may be configured as the concave shaped portion 26.
It is to be noted that a length C between the concave shaped portion 26 and the shaft 2b of the buckle 20 according to the present embodiment in the front view may be set appropriately by adjusting the shapes of the concave shaped portion 26 and the shaft 2b or the position of the base 3a of the belt locking unit 3 on the shaft 2a in the vertical direction. However, the length C may be adjusted appropriately mainly for the purpose of reducing a chance of a contact between the button 8 and the buckle body 2 while the belt is worn and facilitating a work for causing the button 8 to engage with the engaging unit 4. Therefore, it is preferable that the length C is formed so as to have a size to the extent that dimension when the button 8 provided in the trousers to be worn is viewed from the front face (see FIG. 3(a)) can be accommodated.
For example, the length C according to the present embodiment is set to become a length of longer than 1.7 cm in consideration of a fact that a diameter of a top button included in commercially available jeans is 1.7 cm. As a result, the button 8 can easily be introduced to an area provided at an upper side of the engaging unit 4 in an inner diameter side of the buckle body 2. Therefore, it is possible to further improve easiness of the work for causing the button 8 to engage with the engaging unit 4 when a wearer wears the belt.
As described above, according to the buckle 20 of the second embodiment, a part of the clothes is the button provided at an upper end of a front surface of the trousers. Further, the belt locking unit 3 is a pin-shaped member to lock a belt 1 by inserting the belt locking unit 3 into a locking hole 1a of a belt 1. Further, the engaging unit 4 is a part of the belt locking unit 3, and is configured so that the button 8 engages with the concave shaped portion 26 (a second concave shaped portion), which is formed at the upper side thereof by being curved so as to have the convex shape toward the lower side, at the time of wearing the trousers. As a result, since the engaging unit 4 is configured so as to be located at the lower side further, the area provided at the upper side of the engaging unit 4 in the inner diameter side of the buckle body 2 becomes larger. Therefore, it is possible to facilitate the work for causing the button 8 as the part of the clothes to engage with the engaging unit 4 at the time of wearing the belt. Further, by causing the button 8 to engage with the concave shaped portion 26, it is possible to suppress the buckle 20 from shifting the lateral direction with respect to the trousers.

-Third Embodiment-
A buckle 30 according to a third embodiment of the present invention will be described. The buckle 30 according to the present embodiment is different from those according to the embodiments described above in a shape of an engaging unit 34. Hereinafter, the difference will mainly be described with reference to the drawings. Further, the same reference numeral is assigned to each of the similar components to those of the embodiment described above, and their explanation is omitted.
FIG. 7 is a view for explaining the engaging unit 34 according to the third embodiment. The engaging unit 34 according to the present embodiment is formed by reducing a thickness of a substantially central portion of a belt locking unit 3, and is configured so as to include at least one of features of the engaging unit 34 respectively illustrated in FIGS. 7(a) to 7(d). An up down arrow illustrated in FIG. 7(a) indicates a vertical direction in a direction of gravity, and directions indicated by thick arrows illustrated in FIGS. 7(b) to 7(d) indicate a trouser side.
FIG. 7(a) is a view for explaining the engaging unit 34 according to the present embodiment, and is a view when the buckle 30 is viewed from a front face thereof. The engaging unit 34 according to the present embodiment is configured by forming a concave shaped portion 34a that is recessed downward at the substantially central portion of the belt locking unit 3 to become thinner in the vertical direction.
FIG. 7(b) is a view for explaining the engaging unit 34 according to the present embodiment, and is a view when the belt locking unit 3 is viewed from an upper side thereof when a belt is worn. The engaging unit 34 according to the present embodiment is configured by forming a concave shaped portion 34b that is recessed toward the trouser side at the substantially central portion of the belt locking unit 3 to become thinner in a trouser side direction.
FIG. 7(c) is a view for explaining the engaging unit 34 according to the present embodiment, and is a sectional view of the concave shaped portion 34b, taken along a line A-A illustrated in FIG. 7(b). As illustrated in FIG. 7(c), the concave shaped portion 34b is configured so as to be recessed on a surface perpendicular to the trouser side direction.
FIG. 7(d) is a view for explaining the engaging unit 34 according to the present embodiment, and is a view illustrating another example of the sectional view of the concave shaped portion 34b, taken along the line A-A illustrated in FIG. 7(b). As illustrated in FIG. 7(d), the concave shaped portion 34b may be configured so as to be recessed with an inclination with respect to a surface perpendicular to the trouser side direction. Moreover, it is preferable that an inclined surface of the inclination included in the concave shaped portion 34b is configured so as to face upward as illustrated in FIG. 7(d). As a result, the upper side of the concave shaped portion 34b becomes thin, and it becomes easy to cause the concave shaped portion 34b to slip into a lower side of a trouser side of a button 8 at the time of wearing the belt. Therefore, it is possible to further improve easiness of a work for causing the button 8 to engage with the engaging unit 4 when a wearer wears the belt. It is to be noted that the inclination is not limited to a straight line as illustrated in FIG. 7(d), and may be a curved line that curves toward the trouser side, for example.
Even the buckle 30 that includes the engaging unit 34 including at least one of such a concave shaped portion 34a or 34b can also cause the button 8 to easily engage with the engaging unit 4 at the time of wearing the belt, and prevent the trousers from sliding down with respect to the belt.
As described above, according to the buckle 30 of the third embodiment, a part of clothes is the button provided at an upper end of a front surface of the trousers. The belt locking unit 3 is a pin-shaped member to lock a belt 1 by inserting the belt locking unit 3 into a locking hole 1a of the belt 1. The engaging unit 34 is a part of the belt locking unit 3, and is configured so that the button is caused to engage with the concave shaped portion 34a or 34b (a third concave shaped portion) that is formed to become thinner than the other portion. As a result, the portion of the belt locking unit 3, which is caused to engage with the button 8, becomes thinner (or narrower), and it becomes easy to cause such a portion to slip into an area between the button 8 and the trousers (that is, an area in the vicinity of the connecting unit 8a). Therefore, it is possible to improve easiness of the work for causing the button 8 as the part of the clothes to engage with the engaging unit 34 at the time of wearing the belt.

-Fourth Embodiment-
A buckle 40 according to a fourth embodiment of the present invention will be described. The buckle 40 according to the present embodiment is different from those according to the embodiments described above in arrangement and a shape of an engaging unit 44. Hereinafter, the differences will mainly be described with reference to the drawings. Further, the same reference numeral is assigned to each of the similar components to those of the embodiment described above, and their explanation is omitted.
FIG. 8 is a view for explaining the buckle 40 according to the fourth embodiment. It is to be noted that the buckle 40 according to the present embodiment is mainly applied to a belt that is used when slacks as illustrated in FIG. 9 are worn.
FIG. 8(a) is a perspective view of the buckle 30 when a back side (a trouser side) is viewed from the above obliquely. FIG. 8(b) is a rear view when the buckle 40 is viewed from a trouser side. FIG. 8(c) is a top view when the buckle 40 is viewed from an upper side while the belt is worn. Further, up down arrows illustrated in FIGS. 8(a) and 8(b) indicate a vertical direction in a direction of gravity, and a direction indicated by a thick arrow illustrated in FIG. 8(c) indicates the trouser side.
As illustrated in FIGS. 8(a) to 8(c), the engaging unit 44 according to the present embodiment is a part of a shaft 2c that is a lower side of a buckle body 2, and is configured so that a part of the trousers is caused to engage with a hook shaped unit 44a that is formed so as to protrude from the shaft 2c to the trouser side and to be curved (or bend) upward.
Here, the part of the trousers with which the engaging unit 44 according to the present embodiment engages will be described with reference to FIG. 9. The part of the trousers mentioned herein is a bottom catch unit 45 that is provided at an obi (waist band) portion of trousers (for example, slacks). The bottom catch unit 45 is a cloth portion for fastening a button 45b that is provided slightly at a left side from the center of an upper end portion of a front surface of the slacks in the front view when viewed from a front face of the slacks. The bottom catch unit 45 is provided so as to protrude from the obi portion described above. At least a lower side 45a thereof is not sewn to the obi portion (see an arrow direction from a dotted line in FIG. 9).
The engaging unit 44 according to the present embodiment for such slacks as a target is provided on the buckle body 2, and is configured so as to engage with the bottom catch unit 45 of the slacks. More specifically, the engaging unit 44 is configured so as to enter the trouser side (a back fabric) of the bottom catch unit 45 while the belt is worn, and hang the lower side 45a of the bottom catch unit 45 to the hook shaped unit 44a. As a result, by inserting the engaging unit 44 into the trouser side (the back fabric) of the bottom catch unit 45 when a wearer wears the belt, it is possible to easily prevent the slacks from sliding down with respect to the belt.
It is to be noted that a shape and arrangement of the engaging unit 44 may be set appropriately so long as the bottom catch unit 45 of the slacks can be supported from the lower side thereof. For example, a position of the engaging unit 44 in a lateral direction of the shaft 2c is not limited to the position illustrated in FIGS. 8(a) to 8(c). The position of the engaging unit 44 can be adjusted appropriately so long as the engaging unit 44 can enter the back side of the bottom catch unit 45 in a state where the buckle 40 is arranged in the center of the front face of the slacks in at least a right side from the center in the rear view of FIG. 8(c). Further, a shape of the engaging unit 44 is also not limited to a rectangular shape as illustrated in FIGS. 8(a) to 8(c), and can be set appropriately. The shape may be a semicircular shape or a rod shape.
It is to be noted that there are some slacks, such as women's slacks, which are configured so that the bottom catch unit 45 illustrated in FIG. 9 protrudes to the right side in the front view. In consideration of a situation that such slacks are used, the position of the engaging unit 44 included in the buckle 40 may be set to an opposite side in the lateral direction, that is, a position of the left side when the buckle 40 is viewed from the back side thereof.
As described above, according to the buckle 40 of the fourth embodiment, a part of clothes is the bottom catch unit 45 provided so as to protrude from the obi portion of the trousers at the upper end of the front surface of the trousers. Further, the buckle body 2 has an annular structure, and includes two shafts substantially parallel to each other, which face up and down. Further, the engaging unit 44 is the part of the buckle body 2, and is configured so as to protrude toward the trouser side from the shaft 2c that is a lower side of the two shafts and so that the bottom catch unit 45 engages with the hook shaped unit 44a that is formed by bending upward at the time of wearing the trousers. This makes it possible to prevent the slacks that does not have a so-called top button from sliding down.

The back plate unit 52b is a flat plate-shaped member formed in a substantially rectangular shape, and is configured so as to cover the trouser side of the buckle 50. The belt fixing unit 52c is rotatably provided at one end side of the back plate unit 52b, and the one end of the belt 1 is fixed between the back plate unit 52b and the belt fixing unit 52c. Further, the locking unit 53 is rotatably provided at the other end side of the back plate unit 52b, and the other end of the belt 1 is locked between the back plate unit 52b and the locking unit 53. Further, an opening as the engaging unit 54 is formed in the back plate unit 52b. Details of the engaging unit 54 will be described later with reference to FIG. 11.
The belt fixing unit 52c is provided at the trouser side of the buckle body 52 so as to be rotatable (capable of opening and closing) via a rotary shaft 52a on one end of the buckle body 52. The belt fixing unit 52c holds the belt 1 by being closed after the belt 1 is inserted between the belt fixing unit 52c and the back plate unit 52b in a state of being opened by using the rotary shaft 52a as a fulcrum, whereby the one end of the belt 1 is fixed to the buckle body 52.
The locking unit 53 is a flat plate-shaped member formed in a substantially rectangular shape, and is configured so as to cover a front side of the buckle 50. The locking unit 53 is provided at the other end of the buckle body 52 so as to be rotatable (capable of opening and closing) via a rotary shaft 53a. The locking unit 53 holds the belt 1 by being closed after the other end of the belt 1 is inserted between the locking unit 53 and a back plate unit in a state of being opened by using the rotary shaft 53a as a fulcrum (see a direction of a dotted arrow in FIG. 10(b)), whereby the one end of the belt 1 is locked to the buckle body 52.
The configuration of the buckle 50 to which the present invention is applied has been described above. Hereinafter, details of the engaging unit 54 included in the buckle 50 will be described.
FIG. 11 is a view for explaining a shape of the engaging unit 54 according to the present embodiment. FIG. 11(a) is a rear view when the back plate unit 52b of the buckle body 2 is viewed from the trouser side. FIG. 11(b) is a top view when the back plate unit 52b is viewed from the above while the belt is worn. FIG. 11(c) is a side view when the back plate unit 52b is viewed from the side while the belt is worn. An up down arrow illustrated in FIG. 11(a) indicates a vertical direction in a direction of gravity, and directions indicated by thick arrows illustrated in FIGS. 11(b) and 11(c) indicate a body side (that is, the trouser side) in a case where the buckle 50 is used while trousers are worn. It is to be noted that FIG. 11 is mainly illustrated for explaining shapes of the back plate unit 52b of the buckle body 52 and the engaging unit 54, and the belt fixing unit 52c and a hole through which the belt passes at the time of wearing the belt are omitted (the same applies to FIGS. 12 and 13, which will be described later).
As illustrated in FIG. 11(a), the engaging unit 54 according to the present embodiment is an opening that is formed at a substantially center of the back plate unit 52b (a position where it overlaps with a top button while the belt is worn). The engaging unit 54 according to the present embodiment has a convex shape including a U-shaped portion that protrudes toward a lower side. A size of the engaging unit 54 may be set appropriately on the premise that a button 8 as a part of the trousers can be introduced. For example, a width A of the engaging unit 54 in a lateral direction is set to a length longer than 1.7 cm, for example, in consideration of a size of the top button provided on the jeans described above. Further, a length B in the vertical direction is set to a length longer than 1.5 mm, for example, in consideration of a thickness of the top button.
By forming the opening (the engaging unit 54) with such a size in the back plate unit 52b, it is possible to introduce the button 8 to the engaging unit 54 at the time of wearing the belt. Therefore, it is possible to support the button 8 from the lower side thereof by hanging the button 8, in particular, a connecting unit 8a thereof to a lower end 54a of the engaging unit 54. This makes it possible to prevent the trousers from sliding down with respect to the belt while the belt provided with the buckle 50 is worn.
Further, the engaging unit 54 according to the present embodiment may include a feature illustrated in FIGS. 11(b) and 11(c). Namely, the engaging unit 54 may be configured so that at least a part of an opening surface of the engaging unit 54 face upward (including obliquely upward) by causing the lower end 54a as at least a part of the engaging unit 54 to protrude toward the trouser side. By configuring the engaging unit 54 in this manner, it is possible not only to increase an area of the opening surface of the engaging unit 54, and it is possible but also to make an angle for inclining the button 8, which is required when the button 8 is introduced to the engaging unit 54 at the time of wearing the belt, gentler. Therefore, it is possible to improve easiness of a work that a wearer causes the button 8 to engage with the engaging unit 4 at the time of wearing the belt.
It is to be noted that the shape of the engaging unit 54 is not limited to one illustrated in FIG. 11, and may include various shapes so long as the engaging unit 54 can engage with the button 8 and support the button 8 from the lower side thereof.
FIG. 12 is a view for explaining another example of the shape of the engaging unit 54 according to the present embodiment. FIGS. 12(a) to 12(c) illustrate a rear view when the buckle 50 is viewed from the back side thereof (the trouser side). It is to be noted that an up down arrow illustrated at a left side of each of FIGS. 12(a) to 12(c) indicates the vertical direction corresponding to the direction of gravity while the trousers are worn.
As illustrated in FIGS. 12(a) and 12(b), the engaging unit 54 is not limited to the shape illustrated in FIG. 11(a), and may be a rectangular shape or a semicircular shape. Further, although it is not illustrated, it may be a triangular shape that has an apex at a lower side. Namely, the lower end 54a of the engaging unit 54 may appropriately be set to a linear shape, a curved shape, or an apex angle shape of a triangle.
Further, the engaging unit 54 may be formed so as to reach at least one end of the back plate unit 52b. For example, as illustrated in FIG. 12(c), the engaging unit 54 may be formed so that an end portion at a right side when viewed from the back side of the back plate unit 52b is opened. By forming the engaging unit 54 in this manner, it is possible to introduce the button 8 to the engaging unit 54 from the side (that is, from a lateral direction) at the time of wearing the belt. Therefore, it is possible to cause the button 8 to engage with the engaging unit 54 more easily.
It is to be noted that a length A in a right-and-left width direction of the engaging unit 54 and a length B in the vertical direction illustrated in FIGS. 12(a) and 12(b) are similar to those that have been explained with respect to FIG. 11(a). However, the length B illustrated in FIG. 12(c) is set to be longer than a length by which the connecting unit 8a (FIG. 3(b)) of the button 8 can be introduced. For example, the length B may be set to a length longer than 8mm in consideration of a situation that a width of the connecting unit 8a (rigid) of commercially available jeans is 8 mm. Further, in a case where the connecting unit 8a of the button 8 as a target is a sewing thread, the length B may be set to a length that is equal to or longer than 3 mm, for example. It is to be noted that although it is not illustrated in FIG. 12, a part of the engaging unit 54 including at least the lower end 54a may be configured so as to protrude toward the trouser side as well as one that has been explained with reference to FIGS. 11(b) and 11(c).
Furthermore, the engaging unit 54 may have a shape as illustrated in FIG. 13. FIG. 13(a) illustrates a rear view when the buckle 50 is viewed from the back side (the trouser side). FIG. 13(b) illustrates a left side view when the buckle 50 is viewed from the left side. FIG. 13(c) illustrates a right side view when the buckle 50 is viewed from the right side. FIG. 13(d) illustrates a perspective view when the buckle 50 is viewed from the above of the back side. Namely, as illustrated in FIGS. 13(a) and 13(d), the engaging unit 54 may be provided so as to cover the back plate unit 52b up to an end portion thereof in the lateral direction. In this case, as illustrated in FIGS. 13(b), 13(c), and 13(d), the engaging unit 54 may be configured so that an opening surface formed by the back plate unit 52b and the engaging unit 54 faces upward. In a case where the engaging unit 54 has such a shape, it is possible to introduce the button 8 to the opening formed in the engaging unit 54 more easily at the time of wearing the trousers. Therefore, it is possible to cause the button 8 to engage with the engaging unit 54 more easily.
Thus, the shape of the engaging unit 54 according to the present embodiment is not limited particularly, and may be set appropriately so long as the engaging unit 54 can engage with the button 8.
As described above, according to the buckle 50 of the fifth embodiment, the part of the clothes is the button provided at the upper end of the front surface of the trousers. Further, the buckle body 52 includes the back plate unit 52b provided at the clothes side and the belt fixing unit 52c provided in the back plate unit 52b to fix one end of the belt 1. Further, the engaging unit 54 is the opening provided in the back plate unit 52b, and the lower end 54a of the opening has a protruding portion (the protruding lower end 54a) that protrudes toward the trouser side. The engaging unit 54 is configured so that the button 8 is caused to engage with the opening surface facing upward by means of the protruding portion. This makes it possible to apply a function of preventing the clothes such as the trousers according to the present invention from sliding down to even a buckle that does not have the locking unit with the pin shaped member described above.

-Sixth Embodiment-
A buckle 70 according to a sixth embodiment of the present invention will be described. The buckle 70 according to the present embodiment is different from those according to the embodiments described above in a shape of a belt locking unit 3. Hereinafter, differences from the buckle 20 according to the second embodiment (see FIG. 5) will particularly be described with reference to FIG. 18. Further, the same reference numeral is assigned to each of the similar components to those of the embodiment described above, and their explanation is omitted.
FIG. 18 is a perspective view of the belt locking unit 3 included in the buckle 70 according to the present embodiment when viewed from the above of a body side (a trouser side). The belt locking unit 3 according to the present embodiment has protrusion shaped portions 71a and 71b. The protrusion shaped portions 71a and 71b are formed so as to protrude upward from both sides of an engaging unit 24, that is, positions close to the engaging unit 24 in a lateral direction of the engaging unit 24, or consecutive positions to the concave shaped portion 26 in the lateral direction of the engaging unit 24. According to such a configuration, even in a case where a force is applied to the buckle 70 so as to shift the buckle 70 in the lateral direction with respect to trousers in a state where a button 8 is caused to engage with the engaging unit 24, the button 8, in particular, a connecting unit 8a is hung to the protrusion shaped portions 71a and 71b, and movement of the buckle 70 in the lateral direction is restricted. Therefore, it is possible to suppress the buckle 70 from shifting in the lateral direction with respect to the trousers more certainly.
It is to be noted that the belt locking unit 3 according to the present embodiment does not necessarily have both of the protrusion shaped portions 71a and 71b, and may include at least one of the protrusion shaped portions (71a or 71b). Further, the protrusion shaped portions 71a and 71b can be applied not only to the belt locking unit 3 according to the second embodiment described above, but also to the belt locking unit 3 according to the third embodiment, which has been explained with reference to FIG. 7, so long as there is no contradiction in all of the belt locking units 3 respectively provided with the engaging units, which have been explained in the specification.
As described above, according to the buckle 70 of the sixth embodiment, the belt locking unit 3 further includes the protrusion shaped portions 71a and 71b that protrude upward at the positions close to the engaging unit 24 in at least one lateral direction of the engaging unit 24. As a result, even in a case where a force acting to shift the buckle 70 to the right or left is applied, the part of the clothes that engages with the engaging unit 24 is hung to the protrusion shaped portions 71a and 71b. Therefore, it is possible to suppress the buckle 70 from shifting in the lateral direction with respect to the trousers more certainly.

-Seventh Embodiment-
A belt 200 according to a seventh embodiment of the present invention will be described. It is to be noted that terms of the belt 200, which will be used in the following explanation, refer to the whole belt including a buckle body. Further, a portion corresponding to a term "belt 1" that has been used in the explanation of each of the embodiments described above, that is, a band portion whose one end is fixed to the buckle body is also called as a belt 1 or a belt (band unit) 1 in the following explanation.
The belt 200 according to the present embodiment is different from the embodiments described above in that a protection member 201 is further provided and an engaging unit 203 is provided in the protection member 201.

It is to be noted that a shape and arrangement of the engaging unit 121 may be set appropriately so long as the pin loop 230 can be hung and supported from a lower side thereof. For example, as illustrated in FIGS. 22(a) and 22(b), the engaging unit 121 may protrude upward from a side surface of the trouser side of the belt locking unit 3 so as to be curved, or as illustrated in FIGS. 22(c) and 22(d), the engaging unit 121 may protrude straight upward from an upper side of the belt locking unit 3. Further, as illustrated in FIG. 22(a) and 22(c), the engaging unit 121 may have a T shape in which an upper end portion of the rod shaped unit extends in the lateral direction, or may be a rod shape as illustrated in FIGS. 22(b) and 22(d). Namely, the shape and the arrangement of the engaging unit 121 may be changed appropriately from the viewpoint of easiness of engagement with the pin loop 230.
As described above, according to the buckle 120 of the ninth embodiment, the part of the clothes is the pin loop 230 provided in the obi portion of the trousers at the upper end of the front surface of the trousers, and the engaging unit 121 has the rod shaped unit that extends upward from the belt locking unit 3. The buckle 120 is configured so that the pin loop 230 engages with the rod shaped unit by inserting the rod shaped unit into the pin loop 230. Even by such a configuration, it is possible to prevent the slacks from sliding down with respect to the belt easily, and it is also possible to suppress the buckle 120 from shifting in the lateral direction with respect to the slacks.

Namely, the buckle 70 illustrated in FIG. 15(a) forms the space 7 so that the shaft 2b of the upper side of the buckle body 2 has a convex shape on a front side with respect to a pin shaped member with a conventional rod shape. Even by such a configuration, by introducing the button 8 to the space 7 from the upper side to the lower side, it is possible to cause the button 8 to engage with the pin shaped member of the conventional rod shape to support the button 8 from the lower side.
Further, the engaging unit described above can also be formed with a configuration as illustrated in FIG. 15(b). Namely, an engaging unit 84 included in a buckle 80 illustrated in FIG. 15(b) is configured so as to protrude from a pin shaped member of a rod shape to a trouser side and have an opening 84a that opens in a vertical direction. According to the buckle 80 configured in this manner, it is possible to engage with the button 8 by introducing the button 8 into the opening 84a from the above at the time of wearing the belt, and this makes it possible to support the button 8 from the lower side.
Furthermore, the engaging unit described above can also be formed with a configuration as illustrated in FIGS. 15(c) and 15(d), for example. Namely, an engaging unit 94 included in a buckle 90 illustrated in FIGS. 15(c) and 15(d) is formed so as to protrude from a pin shaped member of a rod shape toward a trouser side and bend upward, and is configured so as to have a concave shaped portion 94a formed on an upper end surface thereof. According to even the buckle 90 configured in this manner, it is possible to support the button 8 from the lower side by causing the button 8, in particular, the connecting unit 8a to engage with the concave shaped portion 94a at the time of wearing the belt.
Moreover, the present invention can also be applied to a buckle 100 having a shape as illustrated in FIG. 16.
FIG. 16 is a view illustrating the buckle 100 to which the present invention is applied. FIG. 16(a) illustrates a front view of the buckle 100 when viewed from a front face thereof. FIG. 16(b) illustrates a top view of the buckle 100 when viewed from the above while a belt is worn. FIG. 16(c) illustrates a state where the belt 1 is fastened at the time of wearing trousers by using the buckle 100.
As illustrated in FIG. 16(a), a buckle body 2 constituting the buckle 100 includes a shaft 2d provided substantially parallel to a shaft 2a in a substantially central portion in a lateral direction thereof. In the buckle 100, one end of the belt 1 is fixed to the shaft 2d, and a ring-shaped base 3a formed at one end of the belt locking unit 3 is rotatably fixed.
As illustrated in FIG. 16(b), the belt locking unit 3 included in the buckle 100 has an engaging unit 104 that protrudes from the base 3a to a trouser side and is formed in a substantially rectangular and annular shape when viewed from the above. As illustrated in FIG. 16(b), the engaging unit 104 becomes a convex shape toward the trouser side in a substantially central portion of the buckle 100 in the lateral direction, and forms a concave shaped portion 104a at the trouser side of an inner diameter thereof. As a result, a space 7 is formed between the concave shaped portion 104a and the shaft 2b in the substantially central portion of the buckle 100 in the lateral direction. Even by the engaging unit 104 configured in this manner, it is possible to hang the button introduced into the space 7 when the belt is fastened at the time of wearing the trousers to support the button from the lower side.
It is to be noted that the engaging unit 104 according to the present embodiment is not limited to the rectangular shape as illustrated in FIG. 16(b), and may be an elliptic shape or a circular shape. Further, the space 7 illustrated in FIG. 16(b) is formed between the concave shaped portion 104a and the shaft 2b, but a space at the inner diameter of the engaging unit 104 can be regarded as the space 7. In that case, a portion at a front surface (the opposite side of the trouser side) of the inner diameter of the engaging unit 104 may be arranged at the trouser side more than the trouser side of the shaft 2b. Even in a case where the buckle 100 is configured in this manner, by introducing the button into the space at the inner diameter of the engaging unit 104 when the belt is fastened at the time of wearing the trousers, it is possible to support the button from the lower side.
It is to be noted that in a case where the belt 1 is fastened by using the buckle 100 at the time of wearing the trousers, as illustrated in FIG. 16(c), it is possible to visually recognize the shaft 2a of the buckle body 2 in the front view.
Furthermore, the present invention can also be applied to a buckle 500 having a shape as illustrated in FIG. 28.
FIG. 28 is a perspective view of the buckle 500 to which the present invention is applied when viewed from the above of a trouser side. In order to clarify the feature, a belt locking unit is omitted. As illustrated in FIG. 28, the buckle 500 includes two shafts 2d and 2e that are substantially parallel to a shaft 2a and connects a shaft 2b of an upper side of a buckle body 2 to a shaft 2c of a lower side thereof. The buckle 500 further includes an engaging unit 501 configured so as to connect the shafts 2d and 2e to each other in a lateral direction. The engaging unit 501 is configured so as to be located at the trouser side compared with at least the shaft 2c when the buckle 500 is viewed from the above (unillustrated). Even by the engaging unit 501 configured in this manner, it is possible to support the button from the lower side thereof by hooking the button on a concave shaped portion 501a formed in the engaging unit 501 when the belt is fastened at the time of wearing the trousers.
Further, the clothes in the present specification such as the trousers include skirts. Further, the buckles described above (10, 20, 30, 40, 50, 60, 70, 80, 90, 100 and the like) are premised on the general usage mode of the belt. Namely, the buckles according to the embodiments described above are configured on the premise that a belt for clothes is used by being wound from a front left side of trousers when viewed from a wearer (after passing through a belt loop at the front left side when viewed from the wearer). Therefore, in a case where the opposite usage mode (that is, a mode that the belt is used by being wound from a front right side of the trousers) is premised, in order to exhibit the similar technical effects, for example, it is appropriately modified such as reversing of the vertical direction.
It is to be noted that at the time of the opposite usage mode (that is, the mode that the belt is used by being wound from the front right side of the trousers), it is possible to use the engaging unit and the hook shaped unit described above by hooking them on a part of the clothes when clothes such as one-piece are worn, for example. According to such a using method, by hooking the engaging unit on the part of the clothes, it is possible to freely set the position of the buckle at the time of wearing the clothes in accordance with the clothes, and it is possible to suppress the buckle from shifting downward with respect to the clothes.
