Description

[Detailed description of the invention] (Field of industrial application) The present invention is a invention regarding a synthetic resin buckle that is attached to suspenders, etc. used when sports pants such as ski pants are worn hanging from the shoulders. be.

(Prior art) Buckles known before this application are, for example,
The invention published in the Publication of Utility Model No. 179819 and the invention published in the Publication of Utility Model Publication No. 1983-31935 are known, but the former is a device for hanging the free end of the belt on the base frame. A rod is installed horizontally, a locking body is connected to the hanging rod so as to be movable up and down, and support rods for abutting and locking the locking body are installed horizontally in parallel at regular intervals, and the locking body is It has a configuration in which tooth profiles are carved on the corresponding surfaces of the locking body and the support rod, and has the function of inserting the belt between the locking body and the support rod and sandwiching and fixing the belt between the tooth profiles of both, The latter has an upper mounting rod in the upper part between the left and right side walls, an upper insertion hole, a bottom wall, a lower insertion hole, and a lower installation rod below it,
A notch is made from the upper end of this bottom wall to form a bullet piece, and a circular hole is made approximately in the center of the left and right side walls.The main body has an upwardly shaped pressing part on the upper part, and is locked to the lower part. The shaft of the locking body is attached to the circular hole in the left and right side walls of the main body, and the bullet piece of the main body is attached to the locking body. A small gap is provided between the tip of the locking part and the upper end of the lower mounting rod, the main body and the locking body are integrally molded with synthetic resin, and the belt is attached to the lower mounting rod. It has the structure and function of clamping and fixing the upper end and the distal end of the locking part with a small gap between them.

(Problem to be solved by the invention) In the buckle having the above structure and function, the part of the belt that pinches the tape also performs a locking function to lock and fix the buckle to the belt. Combined with the action of the teeth cut into the tape, the locking portion of the tape is likely to be damaged, and the tape is also likely to discolor due to friction. Since the locking rod or the main body and the locking body are engaged through the tape of the belt, it depends on the friction of the woven surface of the tape, the thickness of the tape, or the rigidity, pliability, etc. There is a drawback that the locking function between the support rod or the main body and the locking body deteriorates over a relatively short period of time, and on the other hand, buckles for suspenders are operated by opening the locking body upward when loosening the tape. Conventionally, there have been many products of the type, and in that case, the part where the length of the tape is adjusted by the locking body is hidden and tends to be difficult to operate.

The purpose of the present invention is to solve the above-mentioned problems by separating the fixing part of the buckle to the tape by clamping the tape and the engaging part of the buckle locking body to the buckle body at separate locations. However, by dispersing the load that was concentrated in one place like conventional products to multiple places, it prevents the deterioration of the shape of the fixing part and the engaging part and the decrease in the fixing strength, and also prevents the tape from being pinched. In addition to reducing stress and significantly reducing tape damage and discoloration, it also relies on simultaneous molding of the main body and locking body by integral molding using injection molding of high-molecular organic synthetic resin materials such as polyamide and polyacetal. Therefore, we have decided to provide a synthetic resin buckle for suspenders, etc., which requires no assembly work and has high production efficiency, whereas conventionally it was necessary to mold the two parts separately and assemble them. exist.

(Structure of the invention, means for solving problems) Hereinafter, the structure of the invention will be explained based on an embodiment of the invention with reference to the drawings. In the upper part of Figures 1 and 2, 1 is the main body of a buckle for suspenders, etc., which consists of a partially rounded rectangular and thin flat body, into which tapes for suspenders, etc. are inserted sequentially from the top. They each have a horizontally long upper insertion hole 2, an intermediate insertion hole 3, a locking hole 4, and a lower insertion hole 5, and the husbands have approximately the same width and are arranged in parallel. The heights of the holes are slightly different, with the upper insertion hole 2 having the largest height, the lower insertion hole 5 having the second largest height, and the intermediate insertion hole 3 and locking hole 4 having similar heights. It has a height about half of the above two. Reference numeral 6 denotes a locking portion C consisting of a raised protrusion or a recessed groove extending across the width of the locking hole 4 near the upper edge of the upper inner wall 4a of the locking hole 4. Formed in the cross section of an equilateral triangle (see Figures 4a and 4b)
do. 7, 8, and 9 are horizontal frames between the upper insertion hole 2 and the intermediate insertion hole 3, between the intermediate insertion hole 3 and the locking hole 4, and between the locking hole 4 and the lower insertion hole 5, and 10 and 11.
6a and 6b are the left and right vertical frames connecting the horizontal frames 7, 8, and 9, respectively, and 6a and 6b are the locking portions C consisting of a convex portion and a concave portion disposed on the outside of the lower part of both vertical frames 10 and 11, which will be described later. It engages with a locking part D provided on the body. 12
13 is a downward U-shaped upper frame that forms the upper insertion hole 2 together with the horizontal frame 7, and 13 is a support shaft 14a, 14b that engages with a support hole of a locking body, which will be described later, at both ends of its lower part.
It is a support frame that is integrally connected to the left and right vertical frames 10 and 11, and is connected by the side edges of both vertical frames 10 and 11, the upper edge 13a of this support frame 13, and the lower edge of the horizontal frame 9. A lower insertion hole 5 is formed. Next, in FIGS. 1a and 1b and the lower part of FIG.
Support holes 17a and 17b drilled at the ends of b are engaged with support shafts 14a and 14b of main body 1 to form a pivot portion L that is rotatably pivotally connected to main body 1. Therefore, its shape forms a thin planar body somewhat similar to a horizontally elongated rectangle, and when locked, the intermediate insertion hole 3 of the main body 1,
It is arranged so as to cover the upper surfaces of the locking hole 4 and the lower insertion hole 5. The supporting pieces 16a and 16b have a locking portion D on their inner surfaces, which is a convex portion 6C that engages with the main body 1.
has. It is preferable that this locking portion D is a convex portion, but in FIG.
a, the locking portion D of the locking body 15 may be a recess. Reference numeral 18 denotes the upper edge of the locking body 15. When the user of the suspenders puts on or takes off his pants, he hooks his fingers on this upper edge 18 and moves upward to release the lock when the buckle is locked. In some cases, it is operated by opening downward. Figure 2 lower part and Figure 4 a
In addition, in FIG. 4b, reference numeral 19 denotes a beak-shaped locking protrusion protruding from the lower surface of the locking body 15, and the locking protrusion 19 has a width close to the full width in the longitudinal direction of the locking hole 4 of the main body 1 to be combined. It has been elevated. The upper surface M is formed as a guide protrusion 20 consisting of both sides having an angle of approximately 90 degrees and a flat top, and the lower surface N is formed as a groove 21 having an angle of approximately 90 degrees. Alternatively, it may be formed as a concavo-convex portion 21a and a tip edge 22 formed at an angle of approximately 90 degrees. Incidentally, the top of the guide protrusion 20 may be somewhat arcuate. 23 is the upper inner wall 4a of the horizontal frame 8 of the main body 1
This is a guide slope that comes into contact with and guides the guide protrusion 20. The main body 1 and the locking body 15 are made by simultaneously molding a polymeric organic synthetic resin material such as polyamide or polyacetal using a molding means such as injection molding. That is, as shown in Fig. 1a and Fig. 1b, the state in which both are unfolded into a planar shape with the pivot portion L, in which both are pivotally connected through the support shafts 14a, 14b and the support holes 17a, 17b, as the pivot, is made into a mold. However, since the pivot portion L is also formed at the same time, the main body 1 and the locking body 15 are made separately using a molding method such as injection molding, as in the past. It is no longer necessary to manually assemble the buckles at the pivot joint L, which reduces the manufacturing process by half and saves the time and effort required for assembly. The main body 1 and locking body 15 made by the above-mentioned molding are made of a strong material with some elasticity, and are sufficient for long-term repeated engagement and disengagement operations as buckles for sports suspenders, etc. I can endure it.

(Function) Although the embodiment of the present invention has the above partial structure,
To explain the function of the buckle, when using the buckle attached to the pants hanger of pants P such as sportswear such as ski pants, insert the buckle into the lower insertion hole 5 of the main body 1 as shown in FIG. Pass the lower tape A for hanging front pants, bend it into a U shape at the upper edge 13a of the support frame 13, hang it downward, and attach it to the support frame 13.
Sew the front and back tapes together at the bottom of the trousers P, cut one of the back tapes, and sew the front tape to the appropriate length to the upper end of the front of the pants P or suspenders. It is fixed to the front suspension 24 of. Therefore, the length of this lower tape A cannot be adjusted by itself. On the other hand, one end 26a of the upper tape B inserted into the buckle main body 1 is sewn to the upper back edge of the pants P or fixed to the rear hanger 25, and the other end 26b is first inserted from the back side of the main body 1 to the upper part. Pass through the insertion hole 2, and then insert the intermediate insertion hole 3 from the front side of the main body 1.
It is then taken out from the back side of the main body 1 through the locking hole 4 to the front side of the main body 1. Finally, it is led out to the back side of the main body 1 through the lower insertion hole 5. During this time,
The locking body 15 rotates downward in the pivot portion L about the support holes 17a and 17b, so as not to interfere with the operation of inserting the upper tape B into each insertion hole of the main body 1. The wearer of the pants should hang the middle part of the upper tape B over his/her shoulders, and then touch the tape end 2.
Adjust the position of 6b with respect to the main body 1 of the buckle to adjust the hanging condition of the pants P, and when the pants P are hung in the best condition, pull up the locking body 15 and further press it against the main body 1. When pressed, the guide slope 23 of the guide protrusion 20 on the upper surface of the tip of the beak-shaped locking strip 19 of the locking body 15 first contacts the edge of the upper inner wall 4a of the locking hole 4 of the main body 1, and then Depending on the inclination of the guiding slope 23 and the elasticity of the locking strip 19, the neck 19a of the locking body 1
By tilting slightly downward from the base 19b of the locking hole 5, the locking member creeps into the locking hole 4 and comes into pressure contact with the upper inner wall 4a of the locking hole 4. On the other hand, the main body 1 and the locking body 15 have a convex portion 6a or a recess 6b that forms a locking portion C on the outer surface of the main body 1 when the locking strip 19 enters into the locking hole 4. Support pieces 16a and 1 on both sides of the locking body 15
They are integrated into one body by engaging with a convex or recessed portion 6c that forms a locking portion D on the inner surface of the main body 1 that engages with a locking portion C of the main body 1. That is, in the case of engagement between the protrusions 6a and 6c, the so-called wallet lock type engagement is performed between the short bar-shaped protrusions, and the recesses 6b and 6c or the protrusions 6a and 6c are engaged. In this case, a normal hemispherical concave-convex engagement is used. When viewed from the side, both support shafts 14a and 1 as shown in FIG.
4b and the fitting portions of the support holes 17a and 17b are used as pivots to form a flat plate. Tape B in this condition
The portion passing through the locking hole 4 of the main body 1 is formed by the distal edge 22 of the locking strip 19 and the groove 21 or the uneven portion 21a and the horizontal frame 9 of the main body 1 over the entire width of the tape. It is firmly clamped between the upper edge, that is, the upper edge of the lower inner wall 4b of the locking hole 4, and will not loosen. As mentioned above, in the present invention, the part where the locking body 15 locks on the main body 1 and the part where the tape B is fixed by being clamped to the main body 1 by the locking body 15 are separate. The locking and clamping are performed well, and the operation is simple. Then, in the opposite manner to the above, hook the upper end of the locking body 15 with your finger and open the locking body 15 downward relative to the main body 1, so that both of them are aligned as shown in FIG. When the tape B is unfolded into a series of flat bodies, the clamping of the tape B is released and the tape B becomes movable relative to the main body 1. Therefore, when the tape B is pulled upward, the tape B is attached to the top and bottom of the main body 1. Insertion holes 2 and 5, intermediate insertion hole 3 and locking hole 4
As the tape slides up, the suspended state of the pants loosens, making it possible to remove the tape from the shoulders.

(Essential Constituent Requirements of the Invention) In the above-mentioned embodiments of the present invention, the essential requirements of the configuration of the present invention are that the main body 1 and the locking body 15 are made of It is a rectangular or rectangular, thin, flat molded body formed by simultaneous molding of high-molecular organic synthetic resin materials such as polyester and polyacetal. The locking body 15 has a locking portion C on its outer surface, and the locking body 15 has a locking portion C on its lower surface that is connected to the upper inner wall 4 of the locking hole 4 of the main body 1.
The raised locking strip 19 and the locking body 15 that come into contact with a
The main body 1 is attached to the inner surface of the support pieces 16a and 16b on both sides of the
It has a locking part D that engages with a locking part C of the main body 1.
When the locking body 15 is rotated and crimped against the body 1, the body 1 and the locking body 15 are engaged by the locking parts C and D, and at the same time, the lower surface N of the locking strip 19 and the locking hole of the main body 1 are engaged. The tape B is characterized by a buckle for sandwiching the tape B between the tape B and the lower inner wall 4b of the tape B.

(Effects of the invention) Since the present invention has the above-described structure and operation, (1) the locking and fixing location between the main body 1 and the locking body 15 and the tape clamping location are separate; In addition, the synthetic resin used is strong, and even after long-term use under heavy loads, the locking and clamping parts will not deform due to wear etc. There is no decrease in pinching strength.

(2) Unlike conventional buckles, where the above-mentioned locking and fixing points and pinching points are made in the same place, they are separate and separate places, so the buckle can be locked and fixed to the tape. Since no force is applied to the tape, and the length of the tape is long enough to apply pinching force, the tape is less prone to damage, abrasion, stains, etc. compared to conventional products that are configured to apply multiple forces.

(3) Since the main body 1 and the locking body 15 are integrally molded at the same time via the pivot joint L, compared to the conventional product where the two parts are first molded separately and then assembled. Since the labor required for assembly can be saved, production efficiency can be improved and production costs can be reduced.If the main body 1 and the locking body 15 are designed in the same color, there will be a difference in color between them, which will reduce the possibility of defective products. It is also advantageous in terms of production in that it has a technical effect that can prevent accidents.

(4) Compared to conventional metal buckles, it is light and has some flexibility even among synthetic resin materials, and
The surface can be finished smoothly and can be colored freely, so it has an excellent design, and although it is strong, it has good contact with the user's body and clothing, and there is no risk of damaging the user's husband or the like.

(5) Unlike metal products, after pressing, there is almost no need for various processing such as deburring, polishing, plating, or painting, so the price is low, and since it is injection molded using simultaneous molding, it is suitable for mass production. .
