Description

TECHNICAL FIELD

[0001] The present invention relates to a safety pin for fastening accessories, more particularly, a safety pin for fastening accessories which can fasten, to an object of fabric material for attachment such as clothes or bags, accessories, for example, simple accessories such as ribbon, name tag and jewelry and portable electronic device such as mobile communication terminal, various electronic chips, speaker, microphone etc..

BACKGROUND ART

[0002] In general, a safety pin is used to fasten simple accessories such as ribbon, name tag and jewelry to clothes or adjust a dress or adjust a scarf or a shawl so that it is not disheveled. Furthermore, such a safety pin is also used as means for fastening a tag indicating product quality, price, precautions etc. to a product such as clothes, bags etc..

[0003] Meanwhile, in recent, a variety of electronic chips such as ID card and traffic card and also portable electronic devices such as mobile communication terminal, PMP, MP3 player, speaker, microphone etc. gradually become smaller and lighter and accordingly are supplied in a smaller form even than a palm.

[0004] Such portable electronic device is taken out and used, if necessary, while being mainly put and carried in a pocket or bag. However, in this case, there is a problem that the portable electronic device may depart from a carrying place, i.e., the pocket or bag, to be lost or damaged since the small-sized portable electronic device is not stored while being fastened to the pocket or bag.

[0005] As a solution for solving such a problem, a hangable connection string fixed to the portable electronic device is used by being hung on a neck. However, there is a problem that in this case, since the portable electronic device hanging from the neck is not fixed, the portable electronic device sways according to movement of the body and thus is bumped against an external object to be damaged or hit a portion of the body to cause contusion or put a strain on the neck to cause a disease such as a herniated cervical disc. Such a problem can be solved by carrying the portable electronic device while being fastened to the clothes etc. by attaching the safety pin or tongs to the portable electronic device.

[0006] Such a safety pin is used to attach, to the object for attachment such as clothes and bags, simple accessories such as ribbon, name tag and jewelry, a variety of electronic chips, or portable electronic device such as mobile communication terminal, PMP, MP3 player etc.. However, the conventional safety pin has a problem that the pin is very inconvenient to be worn on or separated from the object for attachment such as clothes and bags. Therefore, in the technical field to which the present invention belongs, a solution is desperately needed which can solve the problem.

BEST MODES FOR CARRYING OUT THE INVENTION

[0026] Hereinafter, preferred examples of the present invention will be described in detail with reference to the attached drawings. In advance, it should be noted that terms or words used in the specification and claims should not be limitedly interpreted as ordinary or lexical meaning, rather should be interpreted as meaning and notion coinciding with technical concepts of the present invention, based on a principle that inventors may properly define the notion of terms in order to describe their own invention in a best manner. Therefore, example described in the specification and configuration illustrated in the drawings are just a most preferred example of the present invention and does not represent all technical concepts of the present invention, and thus it should be understood that there may be various equivalents and modifications which can substitute it at a time point of the present application.

<Example 1>

[0027] Figs.1a and 1b are perspective view illustrating configuration and operation state of a safety pin for fastening accessories according to a first example of the present invention. Fig.1a shows a state where forces are not applied to a loop button part of the safety pin for fastening accessories, and Fig.1b shows a changed state where the forces are applied to the loop button part of the safety pin for fastening accessories is pressed.

[0028] Referring to Figs.1a and 1b, the safety pin for fastening accessories (100) according to the first example of the present invention includes a base part (110), a pin fastening part (120), a pin coupling part (130), and the loop button part (141).

[0029] The base part (110) has a longitudinal body and the body centrally has an internally-threaded accessory-coupling hole (115) for coupling with accessories (not illustrated) having a bolt structure at the center thereof. The accessories can be fixed to the base part (110) by inserting and fastening the bolt provided on the accessories in the accessory-coupling hole (115). Herein, the accessories are meant to include all portable items, for example, simple accessories such as ribbon, name tag and jewelry; a variety of electronic chips such as ID card and traffic card; and portable electronic device such as mobile communication terminal, PMP, MP3 player, subminiature microphone and subminiature speaker. Meanwhile, in the present invention, means for fastening the accessories is not limited to the accessory-coupling hole (115); alternatively, the accessories, of course, may be fastened by means of accessory-catching ring or accessory-hanging string formed on the base part (110) for coupling with the accessories or of adhesive means such as adhesive tape, Velcro tape and cured adhesive provided on underside of the base part (110).

[0030] The pin fastening part (120) is coupled to one end of the base part (110) and has at least one pin (121) fastened to the pin fastening part and extending in a longitudinal direction of the base part (110). Herein, the pin (121) serves to couple the base part (110) with the object of fabric material for attachment such as clothes or bags. The pin may be formed unitarily; however, the pin may be plurally formed so that forces applied to the object for attachment are distributed and thus damage to the object for attachment can be minimized.

[0031] The pin coupling part (130) is coupled to the other end of the base part (110) and has a pin coupling groove (131) in which the pin (121) of the pin fastening part (120) is inserted and coupled. Herein, the pin coupling groove (131) has a form allowing the pin (121) to be inserted and coupled, and preferably is formed such that diameter of the groove gradually decreases as goes inwardly in an insertion direction. This is for the purpose that a firm coupled state can be kept when the pin (121) is completely inserted in the pin coupling groove (131), while ensuring easy insertion of the pin in the grove.

[0032] Meanwhile, for the pin coupling groove (131) of the pin coupling part (130), at least one hole may be formed for easy coupling of the pin (121), or a sponge member (133) such as sponge, loofah and fibrous material may be formed so that the coupling can be effected over larger area.

[0033] In the safety pin for fastening accessories (100) according to the first example of the present invention, the pin fastening part (120) and the pin coupling part (130) are coupled to the one end and the other end of the base part (110), respectively through hinges (125, 135) and thus can be moved toward the outside of the base part (110). In this connection, the pin fastening part (120) and the pin coupling part (130) move by rotating about the hinges (125, 135)toward the outside of the base part (110). Furthermore, it is preferable that the pin fastening part (120) and the pin coupling part (130) are configured such that while the pin fastening part and the pin coupling part can rotate toward the outside of the base part (110), inward rotation of the two parts can be restricted. This is for the purpose of preventing damage to a product due to excessive insertion of the pin (121) into the pin coupling groove (131) while allowing the pin (121) of the pin fastening part (120) to be coupled to and separated from the pin coupling groove (131) of the pin coupling part (130).

[0034] Meanwhile, though the way of coupling the pin fastening part (120) and the pin coupling part (130) to the base part (110) uses the hinges, the present invention is not limited to it; of course, various modifications may be made which allow the pin fastening part (120) and the pin coupling part (130) to move with respect to the base part (110). The loop button part (141) is coupled to the pin fastening part (120) and the pin coupling part (130) and is formed by a loop structure which is deformed by forces applied from the outside and returns to its original form by its own elastic force. In this connection, it is preferable that the pin fastening part (120) and the pin coupling part (130) are connected to the loop button part (141) such that the parts can move together with the loop button part (141) in response to the deformation and restoration of the loop button part. The loop button part (141) is made from elastic rubber or plastic which can be deformed by the forces applied from the outside and be restored; preferably, the loop button part is made from urethane rubber material which has a good elasticity and is easy to produce. Meanwhile, though the loop structure of the loop button part (141) is in the form of circular loop, the present invention is not limited to it; of course, the loop structure may be formed in the form of polygon such as rectangle and octagon.

[0035] Specifically, description will be made of operation state of the safety pin for fastening accessories (100) according to the first example. Fig.1a illustrates an original state of the loop button part (141) where external forces are not applied to the loop button part. The loop button (141) is positioned between the pin fastening part (120) and the pin coupling part (130), and the pin fastening part (120) and the pin coupling part (130) are in a state where any force is not applied to the parts. At this time, the pin fastening part (120) and the pin coupling part (130) are positioned perpendicular to the base part (110) and thus the pin (121) of the pin fastening part (120) remains inserted and coupled in the pin coupling groove (131) of the pin coupling part (130).

[0036] Fig.1b illustrates a state where the external forces are applied to the loop button part (141). The loop button part (141) is deformed by the forces applied in a lateral direction of the base part (110) to deliver oppositely directed forces to the pin fastening part (120) and the pin coupling part (130). Then, the pin fastening part (120) and the pin coupling part (130) each rotate in outward directions about the hinges (125, 135). Accordingly, the pin (121) of the pin fastening part (120) departs from the pin coupling groove (131) of the pin coupling part (130) to be separated from the groove while distance between the pin fastening part (120) and the pin coupling part (130) increases.

[0037] Namely, the safety pin for fastening accessories (100) according to the first example remains in the form as in Fig.1a prior to use or in a state where the safety pin is coupled to the object for attachment; then, in order to couple the safety pin for fastening accessories (100) to the object for attachment or release the safety pin, force is applied to both lateral sides of the loop button part (141) as seen in Fig.1b. Due to the forces, the pin (121) of the pin fastening part (120) is separated from the pin coupling part (130) and thus the safety pin for fastening accessories (100) can be coupled to or released from the object for attachment. When the applied forces are released again, the state is restored where the pin (121) of the pin fastening part (120) is inserted and coupled in the pin coupling groove (131) of the pin coupling part (130) as illustrated in Fig.1a, while the loop button part (141) returns to its original form due to its elasticity.

<Example 2>

[0038] Figs.2a and 2b are perspective views illustrating configuration and operation state of a safety pin for fastening accessories according to a second example of the present invention. Fig.2a illustrates a state where the force are not applied to the loop button part of the safety pin for fastening accessories, and Fig.2b illustrates a changed state where the forces are applied to the loop button part.

[0039] Referring to Figs.2a and 2b, the safety pin for fastening accessories (200) according to the second example of the present invention includes a base part (210), a pin fastening part (220), a pin coupling part (230), and a loop button part (240).

[0040] Hereinafter, in description of the configuration of the safety pin for fastening accessories (200) according to the second example, the same parts as the configuration of the example described above will be briefly described.

[0041] The base part (210) has a longitudinal body and the body centrally has an internally-threaded accessory-coupling hole (215) for coupling with accessories(not illustrated) having a bolt structure at the center thereof.

[0042] The pin fastening part (220) is coupled to one end of the base part (210) and has at least one pin (221) fastened to the pin fastening part and extending in the longitudinal direction of the base part (210).

[0043] The pin coupling part (230) is coupled to the other end of the base part (210) and has a pin coupling groove (231) in which the pin (221) of the pin fastening part (220) is inserted and coupled

[0044] In the safety pin for fastening accessories (200) according to the second example of the present invention, the pin fastening part (220) is fixedly coupled to the base part (210) perpendicular thereto, and only the pin coupling part (230) is hinge-coupled through hinge (235) and thus can be moved toward the outside of the base part (210). In this connection, the pin coupling part (230) moves by rotating about the hinge (235) toward the outside of the base part (210). Furthermore, it is preferable that the pin coupling part (230) is configured such that while the pin coupling part can rotate toward the outside of the base part (210), inward rotation of the part can be restricted.

[0045] Meanwhile, though the pin fastening part (220) is fixed and the pin coupling part (230) is hinge-coupled as described in connection with Figs. 2a and 2b, the present invention is not limited to it; reversely, the pin fastening part (220) may be hinge-coupled and the pin coupling part (230) may be fixed. Furthermore, though the way of coupling the pin coupling part (230) to the base part (210) uses the hinge, the present invention is not limited to it; of course, various modifications may be made which allow the pin coupling part (230) to move with respect to the base part (210).

[0046] The loop button part (240) is coupled to the base part (210) and the pin coupling part (230) and is formed by a loop structure which is deformed by the forces applied from the outside and returns to its original form by its own elastic force. In this connection, it is preferable that the pin coupling part (230) is connected to the loop button part (240) such that the pin coupling part can move together with the loop button part (240) in response to the deformation and restoration of the loop button part. Meanwhile, though the pin coupling part (230) is connected with the loop button part (240) as described with respect to Figs.2a and 2b, the present invention is not limited to it; reversely, only the pin coupling part (220) may be connected with the loop button part (240) in a case where the pin fastening part (220) is hinge-coupled.

[0047] Specifically, description will be made of operation state of the safety pin for fastening accessories (200) according to the second example. Fig. 2a illustrates an original state of the loop button part (240) where the external forces are not applied to the loop button part. The loop button part (240) is provided in such a form that the loop button part can deliver a force to only the pin coupling part (230) between the pin fastening part (220) and the pin coupling part (230), and the pin coupling part (230) is in a state where any force is not applied to the pin coupling part. At this time, the pin fastening part (220) and the pin coupling part (230) are positioned perpendicular to the base part (210) and thus the pin (221) of the pin fastening part (220) remains inserted and coupled in the pin coupling groove (231) of the pin coupling part (230).

[0048] Fig.2b illustrates a state where the external forces are applied to the loop button part (240). The loop button part (240) is deformed by the forces applied in a lateral direction of the base part (210) to deliver an outwardly-directed force to the pin coupling part (230). Then, the pin coupling part (230) rotates in the outward direction about the hinge (235). Accordingly, the pin (221) of the pin fastening part (220) departs from the pin coupling groove (231) of the pin coupling part (230) to be separated from the groove while the pin coupling part (230) moves away from the pin fastening part (220).

<Example 3>

[0049] Figs.3a and 3b are perspective views illustrating configuration and operation state of a safety pin for fastening accessories according to a third example of the present invention. Fig.3a illustrates a state where the force are not applied to the loop button part of the safety pin for fastening accessories, and Fig.3b illustrates a changed state where the forces are applied to the loop button part.

[0050] Referring to Figs.3a and 3b, the safety pin for fastening accessories (300) according to the third example of the present invention includes a base part (310), a pin fastening part (320), and a loop button part (340).

[0051] Hereinafter, in description of the configuration of the safety pin for fastening accessories (300) according to the third example, the same parts as the configuration of the example described above will be briefly described.

[0052] The base part (310) has a longitudinal body and the body centrally has an internally-threaded accessory-coupling hole (315) for coupling with accessories (not illustrated) having a bolt structure at the center thereof.

[0053] In the safety pin for fastening accessories (300) according to the third example of the present invention, the pin fastening part (320) is coupled to one end of the base part (310) through hinge (325) and thus can be moved toward the outside of the base part (310). In this connection, the pin fastening part (320) moves by rotating about the hinge (325) toward the outside of the base part (310). Furthermore, it is preferable that the pin fastening part (320) is configured such that while the pin fastening part can rotate toward the outside of the base part (310), inward rotation of the part can be restricted. Furthermore,
The pin fastening part (320) has at least one pin (321) fixed thereto which extends in the longitudinal direction of the base part (310) and which is curved such that end portion of the pin can be fixed to the other end of the base part (310).

[0054] Meanwhile, though the way of coupling the pin fastening part (320) to the base part (310) uses the hinge, the present invention is not limited to it; of course, various modifications may be made which allow the pin fastening part (320) to move with respect to the base part (310).

[0055] The loop button part (340) is coupled to the base part (310) and the pin fastening part (320) and is formed in a loop structure which is deformed by the forces applied from the outside and returns to its original form by its own elastic force. In this connection, it is preferable that the pin fastening part (320) is connected to the loop button part (340) such that the pin fastening part can move together with the loop button part (340) in response to the deformation and restoration of the loop button part.

[0056] Specifically, description will be made of operation state of the safety pin for fastening accessories (300) according to the third example. Fig. 3a illustrates an original state of the loop button part (340) where the external forces are not applied to the loop button part. The loop button part (340) is provided in such a form that the loop button part can deliver a force to the pin fastening part (320) and the pin fastening (320) is in a state where any force is not applied to the pin fastening part. At this time, the pin fastening part (320) is positioned perpendicular to the base part (310) and thus the pin (321) of the pin fastening part (320) remains fixed to the other end of the base part (310).

[0057] Fig.3b illustrates a state where the external forces are applied to the loop button part (340). The loop button part (340) is deformed by the forces applied in a lateral direction of the base part (310) to deliver an outwardly-directed force to the pin fastening part (320). Then, the pin fastening part (320) rotates in the outward direction about the hinge (325), whereby the pin (321) of the pin fastening part (320) is separated from the base part (310).

[0058] Figs.4a and 4b are perspective views illustrating configuration and operation state of a safety pin for fastening accessories according to a fourth example of the present invention. Fig.4a illustrates a state where the force are not applied to the loop button part of the safety pin for fastening accessories, and Fig.4b illustrates a changed state where the forces are applied to the loop button part.

[0059] Referring to Figs.4a and 4b, the safety pin for fastening accessories (400) according to the fourth example of the present invention includes a base part (410), a first pin fastening part (420), a second pin fastening part (430), and a loop button part (440).

[0060] Hereinafter, in description of the configuration of the safety pin for fastening accessories (400) according to the fourth example, the same parts as the configuration of the example described above will be briefly described.

[0061] The base part (410) has a longitudinal body and the body centrally has an internally-threaded accessory-coupling hole (415) for coupling with accessories(not illustrated) having a bolt structure at the center thereof.

In this connection, the at least one pin (421) fastened to the fist pin fastening part (420) is formed to extend in the longitudinal direction of the base part (410).

[0063] The second pin fastening part (430) is coupled to the other end of the base part (410), and has at least one pin (421) fastened to the second pin fastening part and extending in the longitudinal direction of the base part (410). In this connection, the at least one pin (431) fastened to the second pin fastening part (430) is formed to extend in the longitudinal direction of the base part (410).

[0064] The pins (421, 431) of the first and second pin fastening parts (420, 430) extend in the longitudinal direction of the base part (410) and are curved such that the pins can be fixed to the central portion of the base part (410), as illustrated in Fig.4a. Furthermore, the pins (421) of the first pin fastening part (420) and the pins (431) of the second pin fastening part (430) may be positioned such that end portions of the pins cross at the central portion of the base part (410). However, the present invention is not limited to it; it is evident that the pins (421, 431) of the first and second pin fastening parts (420, 430) may be positioned so as not to cross in a case where the pins are formed with such a length that the pins do not meet each other.

[0065] Meanwhile, though the pins (421, 431) of the first and second pin fastening parts (420, 430) are curved such that the pins can be fixed to the central portion of the base part (410) as described with respect to Fig.4a, the present invention is not limited to it; the pins may be formed so as to be parallel to each other while extending in the longitudinal direction of the base part (410). In this case, it is preferable that the pin (421) of the first pin fastening part (420) and the pin (431) of the second pin fastening part (430) are positioned such that the end portions of the pins cross at the central portion of the base part (410).

[0066] In the safety pin for fastening accessories (400) according to the fourth example of the present invention, the first pin fastening part (420) and the second pin fastening part (430) are coupled to the one end and the other end of the base part (410), respectively through hinges (425, 435) and thus can be moved toward the outside of the base part (410). In this connection, the first and second pin fastening parts (420, 430) move by rotating about the hinges (425, 435) toward the outside of the base part (410). Furthermore, it is preferable that the first and second pin fastening parts (420, 430) are configured such that while the first and second pin fastening parts can rotate toward the outside of the base part (410), inward rotation of the two parts can be restricted.

[0067] Meanwhile, though the way of coupling the first and second pin fastening parts (420, 430) to the base part (410) uses the hinges, the present invention is not limited to it; of course, various modifications may be made which allow the first and second pin fastening parts (420, 430) to move with respect to the base part (410).

[0068] The loop button part (440) is coupled to the first and second pin fastening parts (420, 430) and is formed in a loop structure which is deformed by forces applied from the outside and returns to its original form by its own elastic force. In this connection, it is preferable that the first and second pin fastening parts (420, 430) are connected to the loop button part (440) such that the parts can move together with the loop button part (440) in response to the deformation and restoration of the loop button part.

[0069] Specifically, description will be made of operation state of the safety pin for fastening accessories (400) according to the fourth example. Fig.4a illustrates an original state of the loop button part (440) where external forces are not applied to the loop button part. The loop button (440) is positioned between the first and second pin fastening parts (420, 430) and the first and second pin fastening parts (420, 430) are in a state where any force is not applied to the parts. At this time, the first and second pin fastening parts (420, 430) are positioned perpendicular to the base part (410). The pins (421, 431) of the first and second pin fastening parts (420, 430) remain crossed at the central portion of the base part (410) or remain fixed to the central portion of the base part (410), depending on selected shape of the pins.

[0070] Fig. 4b illustrates a state where the external forces are applied to the loop button part (440). The loop button part (440) is deformed by the forces applied in the lateral direction of the base part (410) to deliver oppositely directed forces to the first and second pin fastening parts (420, 430). Then, the first and second pin fastening part (420, 430) rotate in the outward directions about the hinges (425, 435), respectively. Accordingly, the pins (421, 431) of the first and second pin fastening part (420, 430) are separated upwardly from the base parts (410) while distance between the first pin fastening part (420) and the second pin fastening part (430) increases.

[0071] Figs. 5a and 5b are perspective views illustrating a configuration where an auxiliary elastic spring is added to the safety pin for fastening accessories according to the present invention, Figs.6a and 6b are perspective views illustrating a modified configuration and operation state of the loop button part in the safety pin for fastening accessories according to the present invention, Figs.7a and 7b are side views illustrating another modified configuration and operation state of the loop button part in the safety pin for fastening accessories according to the present invention, and Fig.8 is a perspective view illustrating yet another configuration of the loop button part in the safety pin for fastening accessories according to the present invention. Figs.5 to 7b show examples modified on a basis of the safety pin for fastening accessories according to the first example, and Fig.8 shows examples modified on a basis of the safety pin for fastening accessories according to the fourth example.

[0072] Meanwhile, though the elastic force for operation of the safety pin for fastening accessories is provided only by the loop button parts (141, 240, 340, 440) in the above-described examples, the present invention is not limited to it. As illustrated in Figs.5a and 5b, an auxiliary elastic spring (151) may be further provided which supports elastic force of the loop button parts (141, 240, 340, 440)

[0073] The auxiliary elastic spring may be adapted to move together with the loop button part (141) in response to the deformation and restoration of the loop button part by forming the auxiliary elastic spring (151) inside the loop button part (141) or forming auxiliary elastic springs (154, 155) at the pin fastening part (120) and the pin coupling part (130), respectively.

[0074] In this connection, the auxiliary elastic springs (151, 152, 153) may be formed unitarily inside the loop of the loop button part or formed on both sides of the base part (110), respectively, with the base part positioned in between.

[0075] Furthermore, the auxiliary elastic springs (154, 155) may be formed unitarily at the pin fastening part (120) and the pin coupling part (130) or formed on both sides, respectively.

[0076] In this connection, in the case where the auxiliary elastic springs (154, 155) are formed at the pin fastening part (120) and the pin coupling part (130), respectively, the elasticity of the spring of the pin fastening part (120) may be rendered higher and elasticity of the spring of the pin coupling part (130) may be rendered lower. Accordingly, when user presses the loop button part (141), the pin coupling part (130) with the elasticity of its spring lower firstly moves to release pin coupling and then the pin fastening part (120) with the elasticity of its spring higher moves on completion of releasing of the pin coupling, whereby release and coupling of the pin can be sequentially implemented.

[0077] In this connection, the auxiliary elastic springs (151, 152, 153, 154, 155), of course, may be formed by deforming various springs such as tension spring, coil spring, leaf spring, hinge spring and torsion spring at a proper position.

[0078] Furthermore, though the loop button parts (141, 240,340, 440) are made from elastic rubber or plastic in the examples described above, the present invention is not limited to it; the loop button parts may be made from elastic metal plate or metal ring.

[0079] In such a case, as illustrated in Figs.6a and 6b, for coupling the loop button part (142) with the pin fastening part (120) and the pin coupling part (130) when the loop button part is made from metal ring, formed on the pin fastening part (120) and the pin coupling part (130) may be accommodation members (161) which accommodate the loop button part (142) such that the loop button part pass through the members; the loop button part (142) is firmly coupled with the pin fastening part (120) and the pin coupling part (130) through the accommodation members. The accommodation members (161) may be formed in a structure of the form of ring which is separately provided at the pin fastening part (120) and the pin coupling part (130). Also, in this case, plate-like button members (145) may be further provided on the left and right sides of the loop button part (142), respectively. Furthermore, for supporting the elastic force of the loop button part (142), the auxiliary elastic springs (152) may be further provided on both sides of the base part (110), respectively, with the base part positioned in between. Of course, such button members (145) and the auxiliary elastic springs (152) may not only be applied to the modified examples but also to the examples described previously.

[0080] Alternatively, as illustrated in Figs.7a and 7b, when the loop button part (142) is made from metal ring, accommodation members (162) of hole-shaped structure through which the loop button part (142) can pass may be formed in the pin fastening part (120) and the pin coupling part (130). For the accommodation members (162) of such a form, it is preferable that the hole through which the loop button part (142) passes is formed in the form of elongate hole.

[0081] Furthermore, though the loop button parts (141, 240, 340, 440) are formed in the form of loop structure in the examples described above, the present invention is not limited to it; as illustrated in Fig.8, a semi-circular loop button part (143) is also feasible which is provided only on one side of the base part (110). Such a configuration has an advantage that the safety pin for fastening accessories may be configured to be more compact.

[0082] Furthermore, though a single pin group coupled with the object for attachment is provided for the safety pin for fastening accessories according to the examples described above, the present invention is not limited to it. As illustrated in Fig. 9, the base part (510) has a body further extending in the longitudinal direction, and at least one pin group (520) constituted by the loop button part, the pin fastening part or the pin coupling part may be couple with the base part (510). In this case, it is preferable that the loop button part (144) is formed to connect the respective pin groups (520) with each other, and further provided between the respective pin groups (520) may be button members (146) which can simultaneously operate the loop button parts (144) belonging to the respective pin groups (520). Such a configuration has an advantage that the safety pin for fastening accessories can be firmly bound to the object for attachment when the accessories bound to the safety pin for fastening accessories are of large size.

[0083] Even though the present invention has been described with limited examples and the drawings as above, the present inve ntion is not limited to it, and it is obvious to those skille d in the art that various modifications and alterations may be made without departing from the technical concepts of the present invention and the scope of the following claims and its equivalents.
