JP4656760B2 - Locking device with tape - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a locking tool used to connect or separate two tapes at their ends. Such a locking tool is used, for example, in a front hook type brassiere to connect or separate between two cup parts. Also, in breastfeeding bras, it is used to separate the shoulder strap tape and the tape near the cup portion during breastfeeding to expose the breast, and to reconnect both tapes after breastfeeding.
[0002]
[Prior art]
This type of locking device is basically similar in form to the locking devices used in handbags, shoulder straps and the like of various bags.
[0003]
[Problems to be solved by the invention]
A locking tool used in a brassiere or the like does not require much locking strength but is small. Therefore, it is difficult to use the locking tool used in various bags as it is, as well as making it difficult to use because the place where the finger is applied is too small even if it is reduced in its original form. .
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a locking tool for uses such as a locking tool for a brassiere that is relatively small and does not require a high locking strength.
[0005]
[Means for Solving the Problems]
With tape fasteners of the present invention, there is provided a locking tool comprising a male member attached to an end portion of the female member and the male member side tape attached to the end of the female member side tape, the female member, the a female base buried the female member side tape, made from the engaging portion having the engaging space of the upper surface and lower side surface, left side surface, the upper surface, the female-side base and shape of the "U" A first hole formed by the mold part and a flat first protrusion extending from the female base toward the first hole are provided, and the lower surface protrudes from the female base. a flat second protrusion, the second hole is provided at a position corresponding to the first protrusion of said upper surface, said male member includes a male base buried the male member side tape, for engagement The engaging portion has an engaging protrusion, and a little from the tip. Wherein the small return projections Tsu position is formed.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
The upper surface is provided with a first hole formed by the female base and a U-shaped part, and a flat plate-like first protrusion extending from the female base toward the first hole. preferable.
[0007]
The lower surface is preferably provided with a flat plate-like second protrusion protruding from the female base and a second hole at a position corresponding to the first protrusion on the upper surface.
[0008]
Furthermore, the outer shape of the second protrusion on the lower surface is slightly smaller than the outer shape of the first hole on the upper surface, and the outer shape of the second hole on the lower surface is smaller than the outer shape of the first protrusion on the upper surface. It is convenient for the integral molding to be slightly larger.
[0009]
【Example】
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0010]
Fig.1 (a) is a top view in the state in which two tapes are latched by the latching tool of this invention, FIG.1 (b) is a side view. FIG. 2 is a plan view showing a state in which the two tapes are unlocked.
[0011]
As can be seen from these drawings, the locking device 2 of the present invention comprises a female member 4 and a male member 6, and by connecting or separating them, two tapes (female member side tape 8 and male member side) are obtained. The tape 10) is locked and released. The tape used for the shoulder strap of the brassiere is often a plain weave fabric and is about 14 mm wide. The male and female members are made of a thermoplastic resin and are attached to the tape by injection molding in a mold.
[0012]
Details of the female member 4 are shown in the plan view of FIG. 3A and the cross-sectional view of FIG. The whole is a rectangular thin box having a longitudinal length (16 mm) slightly longer than the width of the tape and a lateral length (10 mm) slightly shorter than the longitudinal length. As shown in FIG. 3B, the left half is a female base 41 embedded with a tape, and the right half is an engaging portion 42 having an engaging space 44.
[0013]
In the female base 41, reference numeral 43 denotes a hole formed by a pin that is pressed in the mold so that the tape is not twisted by injection pressure during injection molding, and the tape is exposed only in this portion.
[0014]
The engaging portion 42 has an engaging space 44 formed between the upper surface and the lower surface. A rectangular first hole 46 (12 mm × 3.3 mm) formed by the female base 41 and the U-shaped portion 45 is formed on the upper surface. Near the center of the first hole 46, a rectangular flat first protrusion 47 (1.5 mm × 3 mm) extending from the female base 41 is provided.
[0015]
The lower surface is complementary to the upper surface, and a rectangular plate-like second protrusion 48 (11.4 mm × 3.2 mm) slightly smaller than the first hole 46 on the upper surface protrudes from the female base 41. . A second hole 49 (2.2 mm × 3 mm) slightly larger than that is provided at a position corresponding to the first protrusion 47 on the upper surface. The second hole 49 is formed by the female base portion 41 and the U-shaped portion 50.
[0016]
Since the left and right end portions of the upper surface and the lower surface are closed by the side members 51 and 52, the engagement space 44 is fully opened only in the engagement direction.
[0017]
Details of the male member 6 are shown in the plan view of FIG. 4A and the cross-sectional view of FIG. The whole is a rectangular flat plate having a longitudinal length (16 mm) slightly longer than the width of the tape and a lateral length (9.9 mm) slightly shorter than the longitudinal length. As shown in FIG. 4B, the right half is a male side base 61 in which a tape is embedded, and the left half is an engaging portion 62 having engaging protrusions.
[0018]
The structure of the male base 61 is the same as that of the female base 41, and a hole 63 is provided for the same reason.
[0019]
The engaging part 62 has a flat engaging protrusion 64 with a rounded tip, and has a width (11.8 mm) slightly shorter than the width of the tape. A small return protrusion 65 (width 2 mm, protrusion height 0.2 mm) is formed at a position slightly returned from the tip.
[0020]
The locking tool 2 is used by a user connecting or removing the female member 4 of the female member side tape 8 and the male member 6 of the male member side tape 10 with a finger.
[0021]
FIG. 5 shows a cross-sectional view of the state in which the female member 4 and the male member 6 are connected. As can be seen from this figure, the male member engaging protrusion 64 is inserted into the female member engaging space 44, and the male member return protrusion 65 is engaged with the wall of the female member “U” -shaped portion. Is stable.
[0022]
In order to release the engagement between the female member 4 and the male member 6, the engagement protrusion 64 of the male member is separated from the engagement space 44 of the female member. For this purpose, as shown in FIG. 6, hold the male member and the female member with both hands, bend it into a “h” shape, and separate the return protrusion 65 away from the wall of the “h” shape portion. By solving. In addition, since the return protrusion of the male member is low, it can be removed by forcibly pulling both sides horizontally and strongly, but this is not the original usage.
[0023]
【The invention's effect】
According to the present invention, it is possible to obtain a simple locking tool for an application that is relatively small and does not require much locking strength. It is suitable, for example, as a locking tool for a front hook type brassiere or a breast feeding bra.
