Background Art
[0002] Normally, when attaching an attachment part such as a connecting ring to an attachment
object, a tape or string (hereinafter referred to as a "piece of tape") is interposed
therebetween. According to conventional inventions, when connecting an attachment
part to a piece of tape, the tape is passed through the through-hole of the connecting
ring so as to form a loop (see, for example,
JP 2003-210233A and Japanese Utility Model Registration No.
3086826).
Disclosure of Invention
Problem to be Solved by the Invention
[0003] According to the conventional inventions, it is necessary to have a piece of tape
looped, as a result of which only that part becomes thicker, impairing the appearance
of the resulting product.
[0004] It is an object of the present invention to provide a method for attaching an attachment
part to a leading end of tape without the need to have the tape looped, and a method
for connecting an attachment part to an attachment object by using such a piece of
tape having the attachment part at a leading end thereof formed by that method. It
is another object of the present invention to provide application examples in which
the above methods are applied to specific commercial products.
Means for Solving Problem
[0005] A method for attaching an attachment part to a leading end of tape includes the steps
of: preparing a piece of tape having a stopper at a leading end thereof, preparing
an attachment part that is attached to the leading end of the tape, the attachment
part having a groove for insertion of the stopper; and inserting the stopper of the
tape into the groove.
[0006] A method for attaching a piece of tape having an attachment part at a leading end
thereof to an attachment object includes the steps of: preparing a piece of tape having
a stopper at a leading end thereof; preparing an attachment part that is attached
to the leading end of the tape, the attachment part having a groove for insertion
of the stopper; inserting the stopper of the tape into the groove; and fixing, to
an attachment object, a trailing end of the tape that is formed by the above steps
and that has the attachment part at the leading end thereof
Effects of the Invention
[0007] According to the present invention, it is possible to attach an attachment part to
a leading end of tape with ease without the need to have a piece of tape looped. Accordingly,
even after the attachment part has been attached to an attachment object, the final
product presents a neat appearance.
Best Mode for Carrying Out the Invention
[0008] In the case of using a synthetic resin stopper, the tape used in the present invention
needs to be made of a material to which or through which a molten resin is attached
or passes without being molten, such as a woven or knitted fabric made of a natural
fiber or a synthetic fiber, or a narrow sheet made of a synthetic resin. Examples
of natural fibers include cotton, hemp, silk, wool, and so on. Examples of synthetic
resins include nylon, polyester, acrylic resin, polypropylene, acetate, rayon, and
so on.
[0009] In the case of using a synthetic resin stopper, the stopper is affixed to a tape
by injection molding or the like. As the synthetic resin, a thermoplastic resin such
as, for example, molten polyacetal resin can be used. The stopper can have any shape
as long as an attachment part can be attached to a leading end of tape, but generally,
it is preferable to use a rod-shape stopper that is easily formed and extends in a
direction perpendicular to the tape.
[0010] Preferably, the step of preparing a piece of tape having a stopper at a leading end
thereof includes the steps of: supplying a tape between dies in which two die holes
that have a shape of the stopper are provided with a narrow spacing therebetween;
injecting a synthetic resin into the die holes so as to simultaneously mold two right
and left ends serving as stoppers; then removing the molded article from the dies;
and lastly cutting between the two ends molded integrally with the tape so as to form
a piece of tape with a stopper. This is because two tape ends each having a stopper
can be obtained efficiently with a single cutting step.
[0011] Instead of using the method in which a synthetic resin is directly injection-molded
onto tape to form stoppers in the tape, it is also possible to use a part molded in
advance in a different location. According to this method, the step of preparing a
piece of tape having a stopper at a leading end thereof includes a step of winding
a leading end of tape around a center portion of a columnar stopper having a slip-off
prevention portion at at least one of both right and left ends thereof and fixing
an overlap of the tape. With this method, it is unnecessary to perform a task such
as performing injection molding on a tape at a predetermined interval, and the production
cost can be reduced as a result. In addition, the method in which injection molding
is performed on a tape has a number of limitations on the type of tape material and
the width, but if a part molded in advance in a different location is used, such limitations
can be reduced. The material of such a part is not limited to a synthetic resin, and
a metal can also be used.
[0012] In the step of preparing an attachment part having a groove for insertion of the
stopper, it is preferable that the groove is open only on an insertion side, and is
closed on an opposite side. This is to prevent the stopper from slipping off.
[0013] It is more preferable that the insertion side opening is also closed after the stopper
has been inserted..
[0014] As a method for closing the insertion side opening, for example, it is possible to
employ a method in which the insertion side opening is closed using a threaded lid,
or a method in which a widened portion is provided in advance at an end of the stopper,
and the widened portion is pushed completely into the groove with the finger so that
the widened portion will not come out.
[0015] To fix the tape having an attachment part at a leading end thereof to an attachment
object, usually, the tape is sewn to the attachment object using a thread, but other
methods are also possible such as thermal fusing and bonding with an adhesive.
[0016] Examples of the "attachment part" and the "attachment object" include:
- (a) the attachment part is a buckle (3D), and the attachment object is a belt (6);
- (b) the attachment part is a connecting ring (3E), and the attachment object is a
set of a bag (7) and a bag handle (71);
- (c) the attachment part is a male and female buckle set (3F, 3G), and the attachment
object is a belt;
- (d) the attachment part is a D-shaped ring (3H, 3L), and the attachment object is
a set of a shoe and a shoe string;
- (e) the attachment part is a display plate (3J), and the attachment object is any
one of a floor carpet (8), wallpaper and clothing; and
- (f) the attachment part is a connector (3K), and the attachment object is a pair of
two pieces of tape.
[0017] Hereinafter, embodiments of the present invention will be described with reference
to the attached drawings.

Embodiment 1
[0019] FIG. 1 shows diagrams illustrating a method for attaching an attachment part 3 to
the leading end of a piece of tape 1, with FIG. 1(a) being a plan view before the
attachment part 3 is attached, and FIG. 1(b) being a plan view after the attachment
part 3 has been attached. FIGS. 2 and 3 show perspective views showing methods for
fixing a stopper. FIGS. 4 to 6 are diagrams illustrating a method for forming stoppers
at leading ends of tape.
[0020] As shown in FIG. 1(a), a rod-shaped synthetic resin stopper 2 is formed at the leading
end of a piece of cloth tape 1. In a main body 31 of an "attachment part" (a "connecting
ring 3" in FIG. 1) that is attached to the tape 1, a groove 32 into which the stopper
2 can be inserted from the side face is formed. The groove 32 is made up of a cylindrical
groove portion 33 into which the stopper is inserted and a flat-plate shaped groove
portion 34 into which the tape is inserted.
[0021] The groove 32 is open on the insertion side 35 so that the stopper 2 can be inserted
therefrom, but the other side 36 does not need to be open. Rather, it is preferable
that the other side 36 is closed in advance so that the stopper 2 will not pass through
the groove 32 and fall off.
[0022] Furthermore, it is preferable to close the insertion side opening 35 as well after
the stopper 2 has been inserted. As a method for closing the insertion side opening
35, it is possible to use, for example, a method in which the insertion side opening
35 is closed with a threaded lid 37 as shown in FIGS. 2(a) and 2(b), or a method in
which a widened portion 21 is provided in advance at an end of the stopper 2, and
the widened portion 21 is pushed completely into a groove 32C with the finger so that
the stopper 2 will not come out from the groove 32C as shown in FIGS. 3(a) and 3(b).
[0023] To form a stopper 2 at the leading end of the tape 1, it is possible to form stoppers
one by one at a leading end of tape by injection molding, but it is preferable to
use a continuous forming method, which will be described below with reference to FIGS.
4 to 6.
[0024] First, a tape 1 to be processed is fed between upper and lower dies 4 and 5 as shown
in FIG. 4 by a continuous supply apparatus. In the upper and lower dies 4 and 5, two
die holes 41, 42; 51, 52 that have a shape corresponding to the shape of stoppers
to be molded are provided with a narrow spacing therebetween. In this embodiment,
two linear die holes are provided with a narrow spacing therebetween. A resin is injected
into the die holes from an injection opening (not shown). After molding, the upper
and lower dies 4 and 5 are separated, and the tape 1 is removed from the dies. In
this manner, the tape 1 having stoppers as shown in FIG. 5 is obtained. Such stoppers
2 are provided at intervals in the long tape 1.
[0025] Subsequently, the tape 1 is cut along the long dashed short dashed line of FIG. 5,
which is between the thus-molded two resin stoppers 2, whereby pieces of the tape
1 that has stoppers 2 on both ends as shown in FIG. 6 can be obtained. Each end serves
as an end of a different piece of the tape.
Embodiment 2
[0026] FIG. 7 shows Embodiment 2 in which the "attachment part" is a buckle 3D and the "attachment
object" is a leather belt 6. In this embodiment, the buckle 3D is attached to the
leading end of the leather belt 6. A piece of tape 1D having a stopper 2D produced
in accordance with Embodiment 1 is fixed by being sandwiched between upper and lower
portions of the leather belt 6 and sewn using a thread 61.
[0027] It should be noted that, in Embodiment 2, the stopper 2D has a trapezoidal cross
section, instead of a columnar cross section.
[0028] For a conventional leather belt, a belt is inserted into a buckle and sewn into a
loop, but according to the method of the present embodiment, it is unnecessary to
form a loop portion in the belt, and the final product presents a neat appearance.
Embodiment 3
[0029] FIG. 8 shows Embodiment 3 in which the "attachment part" is a connecting ring 3E,
and the "attachment object" is a set of a bag 7 and a handle 71. A leading end of
tape 1E having a stopper 2E produced in accordance with Embodiment 1 or 2 is sewn
into a main body of the bag 7. The bag handle 71 is attached to the connecting ring
3E.
[0030] For a conventional handle 71, an end of the handle is inserted into a connecting
ring 3E so as to form a loop, and then fixed, but according to the method of the present
embodiment, it is unnecessary to form a loop portion at the handle end, and the final
product presents a neat appearance.
Embodiment 4
[0031] FIG. 9 shows Embodiment 4 in which the "attachment part" is a male and female buckle
set 3F and 3G, and the "attachment object" is a belt (not shown as it is the same
as that of Embodiment 2 shown in FIG. 7). Pieces of tape 1F and 1G having a stopper
produced in accordance with Embodiment 1 or 2 are attached to the belt. As with the
embodiments described above, it is unnecessary to form a loop portion at the belt
ends, and the final product presents a neat appearance.
Embodiment 5
[0032] FIG. 10 shows Embodiment 5 in which the "attachment part" is a D-shaped ring 3H,
and the "attachment object" is a shoe string. A piece of tape 1H having a stopper
produced in accordance with Embodiment 1 is attached to the D-shaped ring 3H for attaching
a shoe string. As with the embodiments described above, it is unnecessary to form
a loop portion at the leading end of the tape, and the final product presents a neat
appearance. Furthermore, by imparting stretch to the tape 1H, it helps in tightening
the shoe string.
Embodiment 6
[0033] FIG. 11 shows Embodiment 6 in which the "attachment part" is a display plate 3J,
and the "attachment object" is a floor carpet 8, wallpaper or clothing. Two pieces
of tape 1J having a stopper 2J produced in accordance with Embodiment 1 or 2 are fixed
to the floor carpet 8, wallpaper, clothing or the like, and the display plate 3J having
two grooves 32J is attached to the stoppers 2J.
Embodiment 7
[0034] FIG. 12 shows Embodiment 7 in which the "attachment part" is a connector 3K, and
the "attachment object" is a pair of two pieces of tape. Two pieces of tape 1K having
a stopper 2K produced in accordance with Embodiment 1 are prepared, and the ends are
inserted into the connector 3K having two grooves 32K with the ends facing each other,
whereby the two pieces of tape 1K can be connected. In this manner, it is possible
to connect any number of pieces of tape.
Embodiment 8
[0035] FIG. 13 shows Embodiment 8 in which the "attachment part" is a D-shaped ring 3L,
and although the "attachment object" is not shown, the attachment part can be attached
to anything such as a bag, a belt or a shoe, as with the embodiments described above.
[0036] Unlike Embodiments 1 to 7 described above, a stopper 2L is a metal column around
which a leading end of tape is wound, instead of a synthetic resin molded on a tape
by injection molding. As shown in FIG. 13, slip-off prevention portions 22 are formed
at the right and left ends of the stopper 2L, and the thickness of the stopper 2 is
reduced at a center portion 23 by the thickness of the tape. A leading end of tape
is wound around the center portion 23, and a portion where the leading end of tape
overlaps the tape is fixed using a thread 24. It is preferable that, when the tape
sticks out, the unnecessary portion of the tape is cut by a pair of scissors or a
cutter in order to reduce the overlap portion. The thus-produced tape having the stopper
shown in FIG. 13(a) is inserted into a groove 32L of the D-shaped ring 3L.
[0037] Although not shown, according to a variation, the entire tape may be made double-ply.
In this case, it is only necessary to change the stopper such that the groove 32L
is formed to have a thickness that allows the double-ply tape to pass therethrough.
Here, the overlap portion of the tape need not necessarily be fixed with the thread
24, but such may be done. According to this variation, it is possible to eliminate
the need to cut a sticking-out unnecessary tape end. In addition, because the entire
tape is made double-ply, the effect of increasing the strength can be obtained.
[0038] Unlike Embodiments 1 to 7 described above, in Embodiment 8, in order to prevent the
stopper 2L from slipping off, a lid 25 is provided on the stopper insertion direction
side, whereby a finished attachment part shown in FIG. 13(b) is obtained. The thus-formed
D-shaped ring 3L can be attached to an attachment object such as a bag, a belt or
a shoe, as with the embodiments described above.
[0039] In Embodiment 8, because the stopper 2L is made of a metal, a high connecting strength
is obtained. In addition, it is unnecessary to perform a task such as performing injection
molding on a tape, as a result of which the production cost can be reduced. In addition,
the method in which injection molding is performed on a tape (Embodiments 1 to 7)
has a number of limitations on the type of tape material and the width, but Embodiment
8 uses a part molded in advance in a different location, and therefore has few such
limitations.
