Description

[Detailed Description of the Invention] This invention relates to a cap lock knob that locks caps attached to openings of handbags, bags, etc.

Traditionally, lock knobs for seed caps have been made by cutting easily-processed metals such as brass into a lock knob that also serves as a certain decoration. In this case, both bases of the two-fold projecting piece were brazed to each other.
For this reason, not only does cutting and brazing work take time, but they also require skill.
This was also a cause of high costs.

This idea was devised to eliminate the above-mentioned drawbacks, and its purpose was to create a handbag that could be manufactured easily and quickly without any cutting or brazing work, that could be mass-produced, and that was strong and strong. To provide a lock knob for a cap for bags etc. at a generally low price.

An embodiment of this invention will be described below with reference to the drawings.

Reference numerals 1 and 1' denote a pair of left and right caps having a U-shaped cross section and a square shape as a whole, and both bases of the pair of caps are pivotally mounted so that both caps are rotatable. Reference numeral 2 denotes a lock main body attached to the center of one of the pair of caps 1 and 1', and is made of die-casting material such as casting. This lock main body 2 is provided with a pawl 3 at the front end of its bottom surface 2', and the pawl engages directly with the center part of the mating base 1' (see Figure 2), or as shown in Figure 3. Either by engaging with a protrusion 4 formed on the upper surface of the mating cap 1', or by providing a recess 3' in the center of the bottom surface 2' of the lock main body 2 without providing a claw as shown in the fourth figure. The recess 3' is fitted with a protrusion 4 formed on the upper surface of the mating base 1'. Reference numeral 5 denotes a flat recess formed along one side of the rear end of the bottom surface 2' of the lock main body 2, and the recess is recessed from the bottom surface 2' by the thickness of the washer 6. Two protrusions 7 are integrally provided in the flat recess 5 at a predetermined interval. Reference numeral 6 designates a plate-shaped washer that does not protrude from the flat concave portion 5, and the washer 6 has a flat washer portion 6A that is long in the horizontal direction, and a vertical plate portion 6B that extends in the right angle direction at the longitudinal center of the washer portion 6A. The washer part 6A is formed into a substantially T-shape, and the washer part 6A is formed with a cut groove 9 along both end surfaces of the vertical plate part 6B up to the center of the width of the washer part 6A. Bend the protruding piece 10 in half from the center so that it is bent perpendicularly to the wide surface of the washer part 6A, and the vertical plate part 6B returns in the direction of the kerf 9, so that the two-fold projecting piece 10 is folded into the washer. It is formed integrally with the portion 6A. Thus, a space 11 is formed in the two-fold projecting piece 10 between the opposing sides obtained by folding the vertical plate part 6B in half, and the two protrusions 7 of the lock main body 2 are formed in the washer part 6A.
Two holes 8 and 8 are drilled at the positions corresponding to 7.
After the two holes 8 of the washer 6 are fitted into the two protrusions 7, the protrusions are crushed and caulked, and the washer 6 is fixed along one side of the bottom surface 2' of the lock main body 2, It is installed so that the surface of the washer 6 and the bottom surface 2' of the lock main body 2 are flush with each other. The lock body 2 is attached to the center of the cap 1 by attaching the bi-folded protruding piece 1.
A notch hole 13 into which a 0 can be inserted is formed in the upper surface of the central part of the base 1, and the protruding piece 10 is inserted into the notch hole 13.
After inserting the flat part 1 of the wire 12 into the space 11
2' is inserted and the other end of the wire 12 is bent into an L shape, and stored in the U-shaped cross section of the base 1,
When opening the caps 1, 1', when rotating the lock main body 2 in such a manner as to push it backward, the lock main body 2 rotates against the spring elasticity of the wire 12, and the lock main body 2 is rotated by the hand. It is attached so that it will return to its original position when you release it.

As can be seen from the above description, this invention consists of two protrusions integrally provided at a predetermined interval on the bottom of the die-cast lock main body, which are fitted into washers with two corresponding holes. The washer is fixed along one side of the bottom surface of the lock main body by caulking, a part of the washer is cut out, and a bifold projecting piece is integrally formed in the cutout part, Since this is a lock knob for caps of handbags, bags, etc., which allows a flat wire to be inserted into the space formed by the two-folded portion of the protruding piece, the main body of the lock can be formed at once by die-casting. There is no need for cutting at all, and the bifold protruding piece can also be manufactured integrally with the washer by press working without having to braze its base as in the past. As a result, the lock knob for the cap can be formed integrally with the washer by simply inserting a washer with two corresponding holes into the two protrusions integrally formed on the bottom of the lock body and caulking the lock knob. The bi-folded protruding piece is firmly and firmly installed in the specified position, and there is no possibility of damage caused by bending the protruding piece when it is attached by brazing as in the past. Also from this point of view, an excellent effect is achieved in that the cap can be opened and closed reliably. Moreover, since it can be manufactured all at once by die-casting and press processing, it can be mass-produced quickly and can significantly reduce costs, so it can be said to have extremely high practical value in this type of field.
