Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to a dresslet consisting of a decorative metal plate with a design applied to its front side, and a spring clamping portion integrally provided on the back side of the metal plate.

<<Prior Art and its Problems>> In general, what is called a dresslet is used as a decorative fastener for clothes, etc., and is also called a shawl fastener.

This dresslet has a decorative metal plate on which a design is applied on the front side, and a spring clipping part on the back side of the decorative metal plate to which a clipping plate is attached via a spring body so that it can be opened and closed. The structure is such that a sandwiching plate biased by a spring body can open and close other objects inserted into the back side of the metal plate, such as clothes or a shawl.

4 and 5 show conventional examples of such dresslets.

In the figure, 1 is a decorative metal plate formed by casting or die forging with zinc or the like, and the surface side of this decorative metal plate 1 is suitably designed.

Reference numeral 2 denotes a spring clamping portion that is integrally provided on the back side of the decorative metal plate 1.

The spring clipping portion 2 is configured such that the clipping plate 7 can open and close the other object inserted into the back side of the decorative metal plate 1, so generally, a spring clipping portion having the following configuration is used. The fittings are integrally attached to the back side of the decorative metal plate 1 by means such as welding, but conventional dresslets manufactured in this way are expensive to manufacture, and the high temperatures during welding cause the springs to deteriorate. There were problems such as the elasticity of the spring body 6 of the clipper being destroyed and a large number of defective parts being produced.

In other words, the conventional spring clip includes a base plate 3 attached to a decorative metal plate 1, an inclined receiving portion 4 that stands up integrally at a predetermined angle upward from the rear end of the base plate 3, and an inclined receiving portion A spring receiving part 5 provided at the tip of the part 4 and having a cut groove 5a.
and a spring body 6 having upper and lower spring pieces 6b and 6c protruding from the central coil winding part 6a, and a rear part 7 that is engaged with the base plate 3 at the tip part 7c.
Push for opening/closing operation is performed at d, and is composed of a sandwich plate 7 having a pair of left and right flanges 7a, 7a in the center.

Thus, the mounting structure is such that the coiled portion 6a of the spring body 6 is inserted into the cut groove 5a in the spring receiving portion 5 at the tip of the inclined receiving portion 4, and the flange portion 7a at the center of the sandwich plate 7, 7a is slidably joined to both side surfaces of the spring receiving part 5, and the pin 8 is inserted into the pin insertion holes 5b, 7b of the flange parts 7a, 7a and the spring receiving part 5, which are abutted against each other, and the pin 8 is inserted into the pin insertion holes 5b, 7b of the spring receiving part 5. , 7a are rotatably supported by the spring receiving portion 5.

Further, the pin 8 is inserted into the coil winding part 6a, so that the coil winding part 6a is inserted into the notch groove 5.
It is fixedly supported within a.

Therefore, the spring body 6 is compressed into a U-shape between the sandwich plate 7 and the inclined receiving part 4, and its elasticity is activated.
Since the upper spring piece 6b of the spring body 6 acts to push up the rear part 7d of the sandwich plate 7, the sandwich plate 7
The mounting structure is such that the tip 7c of the pin 8 supporting the flange portions 7a, 7a is biased toward the base plate 3 so as to be openable and closable.

Therefore, the coiled portion 6a of the spring body 6 is not supported within the cut groove 5a and is suspended in the air.

Therefore, the coil winding portion 6a has the cut groove 5a.
The pin 8 cannot be inserted unless the pin 8 is lifted and positioned against a pushing force, and this operation is very time-consuming.

For this reason, in general, the spring body 6 and the pincers are directly connected to the angle of the inclined receiving part 4 (the inclined receiving part 4 having a predetermined angle set in advance) at which the spring body 6 is compressed and the elasticity is activated. Rather than assembling the plate 7, the inclined receiving part 4 is made to stand up further than a predetermined angle,
During assembly, the assembly work was performed in a state where the spring body 6 was not activated.

However, in the case of this assembly work, the spring body 6 is compressed by the sandwich plate 7 after assembly, and it is necessary to bend the inclined receiving part 4 to a predetermined angle at which its elasticity is activated, which is very troublesome in the assembly work. In addition, since the material of the inclined receiving portion 4 must be able to withstand bending, there are other problems such as the need to use an expensive material such as brass.

For example, zinc is an inexpensive material suitable for casting, and is also a material with suitable hardness to maintain the slope of the inclined receiving part 4, so the base plate and the inclined receiving part are integrally formed by casting, etc. Although it can be manufactured at low cost by molding, it cannot be used as the inclined receiving part 4 which requires bending because it is weak against bending.

As a solution to this problem, it may be possible to form only the inclined receiving part 4 from bendable brass or the like, but in this case, it is necessary to weld the base plate 3 and the inclined receiving part 4, which are made of different materials, to each other. In addition, the welding process is time-consuming, and the elasticity of the spring body 6 is easily damaged due to high temperatures during welding.Also, droplets from welding adhere to the spring body, causing problems in opening and closing, resulting in defective parts, etc. There was a problem.

In addition, there is a method of low-temperature welding to avoid high temperatures during welding, but in this case, it is necessary to perform copper plating processing on the base plate 3, which creates a vicious cycle of labor and cost. It was hot.

In this way, in conventional dresslets,
The high-cost spring clamp is integrally attached to the back side of the decorative metal plate 1 by means such as welding, which requires a large number of man-hours and has problems such as being unable to be manufactured at a low cost.

<<Purpose of the invention>> The object of this invention is to provide a dresslet that improves the workability of assembly work and can be manufactured at low cost.

《Structure and Effects of the Device〉 In order to achieve the above object, this device includes a decorative metal plate with a design on the front side, and a metal plate provided on the back side of the decorative metal plate with a sandwich. In the dresslet, which consists of a spring sandwiched part in which the plate is biased to open and close via a spring body, a base plate attached to the back side of the decorative metal plate is integrated at a predetermined angle upward from the rear end of the base plate. a spring receiving part that is formed at the tip of the inclined receiving part, has a recess whose bottom surface is a mounting surface for the spring body, and has support shafts protruding from both left and right sides. and a sandwich plate having a mounting hole for the support shaft and a pair of left and right flanges protruding from the center, and the base plate and the decorative metal plate are cast or molded during molding. It is characterized by being integrally formed by forging.

That is, in the case of the present invention, as mentioned above,
On the back side of the decorative metal plate, a spring receiving part is provided at the tip of the inclined receiving part that stands up diagonally upward at a predetermined angle, in which a recessed part whose bottom surface is the mounting surface for the spring body is formed. The spring body can be fixed in the recess without falling off simply by placing the coiled portion at the center of the spring body in the recess.

In addition, support shafts are formed protruding from both the left and right sides of the spring receiver, and mounting holes are provided in the flange of the sandwich plate, so the flange of the sandwich plate can be attached to both sides of the spring receiver. If so, the sandwich plate will inevitably press the spring body placed in the recess, and by simply press-fitting the support shaft of the spring receiver into the mounting hole of the flange, the tip of the sandwich plate will be pressed. It is possible to form a spring clip portion which is biased against the decorative metal plate so as to be openable and closable.

Further, since bending of the inclined receiving portion is not required during assembly work, the inclined receiving portion can be formed at a predetermined angle in advance.

Therefore, the decorative metal plate and the inclined receiving part provided with the spring receiving part can be formed by casting with zinc or the like, die forging, or the like.

Therefore, there is no need to attach the conventional spring clamps, which are expensive, to the decorative metal plate by welding or the like, so the dresslet can be manufactured at extremely low cost.
