Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a buckle with a lock that can be attached to the opening of a bag, trunk, bag, etc.

(Prior Art) As a buckle with a lock, one shown in Japanese Utility Model Publication No. 37-23195 is known.

In other words, as shown in Figure 2 of the above-mentioned public notice, the male lock body includes a lock case with cutouts facing both left and right walls, a bottom cover for closing the lock case, and a cavity on the side. A bag lock is disclosed that includes an operating body having a locking protrusion, a V-shaped strip, and a rotating body having a locking portion.

Furthermore, the use of synthetic resin as a material for latch devices for doors and lids is disclosed in Utility Model Application No. 130867/1987, which contains the specification and drawings on microfilm.

(Problems to be solved by the invention) In the conventional bag lock as described above, the male lock body (insertion tool) is attached to the lock housing, the bottom cover, the operating body, the V-shaped strip, and the rotation. Since the moving body is made up of five parts, the number of man-hours required to manufacture each part increases, which increases the processing cost.Furthermore, it takes a great deal of time to assemble these parts to make the product, which increases the product cost. The problem was that it was difficult to provide inexpensive products.

In addition, the aforementioned operating body (the elastic engagement piece of this invention)
The locking protrusion (locking end) is provided approximately midway between the engagement hole that serves as the fulcrum and the hollow part that serves as the point of action, allowing the male lock body to be detached from the female lock body. In some cases, problems have arisen in that the locking protrusion cannot be removed from the through hole of the female lock body unless the hollow part, which is the point of action, is made a large stroke inward.

(Means for solving the problem) This invention was aimed at solving the problems of conventional locks, and was
Elastic engagement pieces, which are bent into a shape and expanded outward and connected by upper and lower walls provided vertically opposite each other, are provided to extend rearward on both sides of the back surface of the central base, and A knob with a leg is protruded from the tip of the piece, and a locking end is formed on the same plane as the front end surface of the leg and the knob.The insert body is integrally molded with synthetic resin, and the lock bar is The insertion tool is configured such that a locking mechanism made of synthetic resin is fitted into the hole in the upper and lower walls.

(Function) Next, the function will be explained with reference to FIG. The locking mechanism 13 shown in FIG. 2 is fitted into the operating space 11 of the upper and lower walls 10 of the insertion tool 2 with strong pressure using elasticity, and the base shaft 1 of the locking mechanism 13 is fitted using the fitting hole 12 as a fulcrum.

Next, the insertion tool 2 in this state is inserted from behind the elastic engagement piece 6 toward the insertion opening 19 of the receiving tool 3.

The elastic engagement piece 6 is compressed inward against the elasticity while contacting the inner surface of the locking edge 23 of the receiver 3, and the leg portion 7 of the insertion tool 2 is fitted into the cut groove 21 of the receiver 3. It is inserted and guided. When the insertion tool 2 reaches the inner part of the receiver 3, the knob 8 of the insertion tool 2 protrudes from the notch hole 22, and the locking end 9 at the rear end of the insertion tool 2 fits into the cut groove 21 and the notch hole. 22, and the insertion tool 2 and the receiving tool 3 are completely fixed. After fitting the insertion tool 2 connected to the slider B of the slide fastener A into the receiver 3 fixed to the bag C shown in FIG. 1, the key D is inserted into the lock hole 16 of the lock mechanism 13, and the lock When the base shaft 14 of the mechanism 13 is rotated and the lock bar 17 is locked in the locking recess 18 of the elastic engagement piece 6, the elastic engagement piece 6 is prevented from bending inward, and the rear end is locked. The end portion 9 is completely locked without coming off from the locking edge 23, and the insertion tool 2 is reliably connected to the receiving tool 3, so that the opening of the bag body C cannot be opened unnecessarily.

Next, to release the connection between the insertion tool 2 and the receiver 3, insert the key D into the lock hole 16 and rotate it in the opposite direction to the above locking operation to elastically engage the lock bar 17 of the lock mechanism 13. After the engagement piece 6 is released from the locking recess 18, the two knobs 8 are held and pressed inwardly, and the elastic engagement piece 6 is bent inward against its elasticity to secure the rear end. The locking end 9 of the locking edge 23 of the receiver 3
If the insertion tool 2 is pulled out in this state, the insertion tool 2 can be detached from the receiver 3 and separated.

In addition, in the above operation, when temporarily closing the opening of the bag body D, the insertion tool 2 may be simply attached to the receiving tool 3, and locking with a key may be omitted.

(Embodiment) FIG. 2 is an exploded perspective view showing an embodiment of this invention. The buckle 1 consists of an insertion tool 2 and a receiver 3, both of which are integrally formed of synthetic resin by injection molding or the like.

The insertion tool 2 has a ring 5 connecting the slider B of the slide fastener A on the front surface of the central base 4, and is bent in a V shape at the rear end and expands outward.
And a pair of upper and lower walls 1 provided vertically opposite each other.
Elastic engagement pieces 6 connected at 0 are provided to extend rearward on both sides of the back surface of the central base 4, and leg portions 7 are provided at the tips of the elastic engagement pieces 6.
A locking end 9 is formed on the same plane as the front end surfaces of the leg 7 and the knob 8. An operating space 11 is formed between the pair of upper and lower walls 10, and a fitting hole 12 into which the lock mechanism 13 is fitted is provided.

The lock mechanism 13 has a small-diameter fitting part 15 that fits into the fitting hole 12 at both ends of the base shaft 14, a key hole 16 that engages with a separate lock D on the end surface, and a keyhole 16 that engages with a separate lock D. A pair of lock bars 17 are protruded from the left and right sides of the circumferential surface of the insertion tool 2, and the lock mechanism 13 is inserted into the operating space 11 between the upper and lower walls 10 of the central base 4 of the insertion tool 2.
The small-diameter fitting portion 15 of the base shaft 14 is fitted into the fitting hole 12 by applying strong pressure using its elasticity, and the base shaft 14 is rotatably mounted using the fitting hole 12 as a fulcrum.

By rotating the lock bar 17, a locking recess 18 is formed in the inner surface of the elastic engagement piece 6, with the tip thereof abutting and locking.

The receiver 3 is formed into an integral box by injection molding or the like, and is provided with a fitting opening 19 for fitting and removing the insertion tool 2, and has a fitting opening 19 for fitting and removing the insertion tool 2 on both side walls 20, respectively.
A locking edge 2 formed by the notch groove 21 and the notch hole 22 is provided with a notch hole 22 into which the knob 8 is fitted and protrudes, following a notch hole 21 into which the leg portion 7 is inserted and guided.
3, the locking end 9 at the front end of the elastic engagement piece 6 is locked. Further, a through hole 24 is formed on the surface of the receiving tool 3 so that the keyhole 16 of the locking mechanism 13 is exposed when the insertion tool 2 is inserted.

Incidentally, reference numeral 25 shown in FIG. 4 is a mounting rod, which is integrally provided on the surface of the receiver 3, inserted into the mounting portion of the bag body C, etc., and fixed by welding with a cap 26 from the inner surface.

(Effects of the invention) As explained above, in this invention, the main body of the insert for a buckle with a lock is integrally molded from synthetic resin by injection molding, and the locking mechanism is also integrally molded from synthetic resin. Since the tool consists of just two parts, it requires more processing and processing than conventional buckles, which are made up of many parts and are manufactured by bending metal plates, drawing, casting, cutting, etc.
The assembly process is extremely simple, making it possible to provide an efficient and inexpensive product, and since it is made of synthetic resin, the plating does not peel off or rust, it is lightweight, and it can be used in a variety of colors, making it suitable for decorative items. By selecting a color that matches the color of your bag, bag, etc., you can increase the value of your product.

In addition, since the locking end is formed on the same plane as the front end surface of the leg and knob that protrude from the tip of the elastic engagement piece, the locking end can be easily removed when the insertion tool is removed from the receiver. Because it is on the same plane as the knob that acts as the point of action, it has excellent effects such as the receiver and insertion tool can be easily separated by pressing the knob inward with a slight stroke. be.
