Description

[Detailed description of the invention] [Industrial application field] The present invention is provided on one side of a handbag A as shown in FIG. The present invention relates to an improvement in a fastener for bags, which holds a lid B in a closed state by rotating a locking plate 2 so that the upper end of a locking pin 1 comes into contact with the ventral surface of the locking plate 2.

[Conventional technology]

The 10th conventional fastener for this type of bag
It is shown in FIG.

In the drawing, 11 is the main plate, and a groove 11a is cut in the center of the back surface of the main plate.
One end of a is a notch 11b.

A corner part 12a at one end of the L-shaped locking plate 12 is fitted into this notch 11b, and the shaft 13 passes through this corner 12a and both sides of the notch 11b of the main plate 11. , the locking plate 12 with respect to the main plate 11
is rotatably attached.

A screw hole 11c is bored near the other end of the groove 11a in the main plate 11, and is inserted through the hole 14a of the spring plate 14 inserted into the groove 11a, so that the tip thereof corresponds to the locking pin 1. Screw the screw 15 forming the narrow rod portion 15a into the screw hole 11c to remove the spring plate 14.
is attached to the main plate 11.

The tip of the spring plate 14 is pressed against the corner portion 12a of the locking plate 12.

Therefore, as the corner portion 12a is pressed by the pressing force, the locking plate 12 is pressed against the tip of the narrow rod portion 15a of the screw 15, and the lid portion B of the handbag A is closed as described above. It is kept in good condition.

However, when the locking plate 12 is raised away from the narrow rod portion 15a, the spring plate 14 passes the dead center of the corner portion 12a, raises the locking plate 12, and lifts the eyelet C from the narrow rod portion 15a. It can be attached and detached, and the lid part B can be opened and closed.

Further, mounting legs 16 for attaching the main plate to the handbag A are brazed to the main plate 11.

[The problem that the idea aims to solve]

In conventional luggage fasteners, the main plate 11 is formed by cutting a thick metal body, and the mounting legs 16 must be brazed, making them unsuitable for mass production. Ta.

Also, a shaft 13 for attaching the locking plate 12 to the main plate 11
In this case, a pin having a head 13a is used, but in order to prevent the pin from coming off, the end 13b opposite to the head 13a must be caulked.

Therefore, the plating on the opposite end 13b of the pin peeled off due to caulking, which not only caused an unsightly appearance but also caused rust.

Furthermore, the assembly process is complicated and the number of parts increases, such as the need to screw the spring plate 14 with screws 15.

[Purpose of invention]

The present invention is intended to solve the above-mentioned problems with conventional clasps for bags of this type.
By making the main plate into a pressed part, mass production is facilitated, and the shaft for attaching the locking plate to the main plate is not exposed, and it is possible to provide a fastening fitting for bags at low cost that requires fewer assembly steps. purpose.

[Means to solve the problem]

The present invention relates to a means for achieving the above-mentioned object, in which the left and right sides of the main plate part are folded back to form a clamping part, mounting feet are connected and erected at the tips, and a cut part is formed on one side of the main plate part. At the same time, a curved bearing part is formed on both sides, and a locking pin is caulked to the main plate part, and the body has the caulked head protruding from the back side, and the tip of the protrusion into which the shaft is inserted. It consists of a locking plate with a square shape, and a spring plate that is inserted between the clamping parts and has a fitting hole into which the caulking head of the locking pin fits. Insert the protruding piece of the stop plate, have its shaft bearing in the bearing part of the main plate part, fit the caulking head into the insertion hole of the spring plate inserted into the clamping part of the main plate part, and use this spring plate to lock the protruding piece on the stop plate. The tip is pressed.

〔Example〕

Next, an embodiment of the present invention will be described based on FIGS. 1 to 8.

Reference numeral 3 denotes a main plate formed by pressing a flat plate of brass, iron, etc., whose both sides 3a are folded back inward, and between the both sides 3a and the back surface of the main plate 3 there is a sandwiching part 3.
b are formed, and mounting legs 3c are provided in an upright manner at both ends of the both side portions 3a.

Furthermore, a notch 3d is formed on one side of the main plate 3, and both sides thereof form a bearing part 3e which is raised and curved toward the upper surface of the main plate 3. On the outside of this bearing part 3e, there is a hanging wall. 3f are installed in series.

Further, a locking pin 1 is crimped upright on the main plate 3 near the opposite side of the notch 3d, and a swaged head 1a of the locking pin 1 is formed in a hemispherical shape.

Reference numeral 2 denotes a locking plate, and on the back side of one side thereof, an angular projecting piece 2a is provided on both the plane and the side surface, and a shaft 5 is laterally inserted into this projecting piece 2a.

Reference numeral 4 denotes a steel spring plate, and its width on both sides is wide enough to be inserted into the clamping part 3b of the main plate 3. A notch 4a is formed parallel to the width to be inserted into the clamping part 3b, and a cutout 4a is formed in the central part. 4b has increased elasticity.

A fitting hole 4c into which the caulking head 1a of the locking pin 1 is fitted is formed, and a slope 4d is formed on one side near the fitting hole 4c.

In this way, as shown in FIG. 1, the square protrusion 2a of the locking plate 2 is fitted into the notch 3d of the main plate 3, and the shaft 5 is received by the bearing part 3e formed on the main plate 3.

Next, move the spring plate 4 from the side of the protruding piece 2a to the holding part 3b.
At this time, the tip of the spring plate 4 is on the slope 4d.
Due to this formation, the crimping head 1a of the hemispherically protruding locking pin 1 can be easily overcome, and the crimping head 1a is fitted into the insertion hole 4c.

Then, due to the engagement between the insertion hole 4c and the caulking head 1a, the spring plate 4 is prevented from coming out from the holding part 3b, and the center part 4b of the spring plate 4 presses the square protrusion 2a of the locking plate 2. At the same time, the shaft 5 is prevented from coming off from the bearing portion 3e.

The locking plate 2 is pressed against the locking pin 1 by the pressure of the spring plate 4.
When the locking plate 2 is rotated in a direction away from the locking pin 1 and raised, the locking plate 2 is maintained in the upright state by passing the corner-shaped dead center.

[Effect of idea]

As mentioned above, in this invention, the main plate is formed by pressing a flat plate of brass, iron, etc., so continuous molding is possible, and there is no need to braze the mounting feet as in the past, so mass production is possible. can.

In addition, the shaft that rotatably attaches the locking plate to the main plate can be inserted into the protruding piece of the locking plate in advance, so there is no need to swage it after installation as in the past, and there are other problems associated with this. Not only is the problem solved, but it is also hidden by the bearing part formed on the main plate and the inserted spring plate, so there is no need for plating.

By simply inserting the spring plate into the clamping part of the main plate, the shaft of the locking plate is prevented from slipping out, the square protrusion is biased, and the caulking head of the locking pin is inserted into the insertion hole. This also prevents the spring plate from coming off.

Therefore, compared to the past, the assembly process is greatly simplified, and together with the main plate being made into parts by pressing, costs can be significantly reduced.
