Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a structure for attaching a coin selector to a vending machine, etc.
As described in Japanese Patent No. 38753, this invention relates to a coin selector mounting structure for detachably mounting a unitized coin selector on an adapter fixedly provided inside a vending machine or the like.

(Prior Art) Conventional coin selector mounting structures of this type generally have locking pins protruding from the left and right sides of the coin selector in groove-shaped configurations, as described in Japanese Utility Model Publication No. 57-38753. The coin selector is configured to be removably attached to the adapter by inserting and locking into the approximately L-shaped locking notches provided on the left and right mounting side walls of the adapter. In order to prevent the locking pin from slipping out of the locking cutout of the adapter,
As shown in FIG. 7, a latch 20 is provided on the left and right mounting side walls 6 of the adapter 4, and after the locking pin 2 is inserted into the locking notch 5, the latch 20 is attached to the protruding outer end of the locking pin 2. The locking pin can be locked and restrained elastically by a spring 21, or the locking pin can be locked using a spring 22 formed by bending a spring steel wire into a special shape, as shown in FIG. It is configured to be elastically restrained within the stop notch 5.

(Problem to be solved by the invention) However, the conventional technology as shown in Fig. 7 has a problem that the number of parts is large and assembly is laborious, resulting in high cost. It is difficult to mold them into the same shape, and it is not easy to adjust them to the correct engagement position and tighten and fix them with screws, so there is a problem that assembly is time-consuming and costs are similarly high.

The present invention eliminates the above-mentioned problems by providing a retaining piece that is inexpensively manufactured by molding a synthetic resin material and that can be easily attached to the adapter without using screws or adjusting the attachment position. This aims to reduce the manufacturing cost of the coin selector mounting device.

(Means for solving the problem) Therefore, the present invention, as shown in Fig. 1,
A channel-shaped adapter 4 is provided on the left and right side surfaces 1 into which a coin selector 3 having a locking pin 2 can be removably fitted and attached, and the adapter 4 has a substantially L-shaped locking notch into which the locking pin is inserted. In the coin selector mounting structure in which 5 is opened at the side edges of the left and right mounting side walls of the adapter,
A long and thin holding piece 7 made of synthetic resin is provided to hold the locking pin 2 of the coin selector 3 so that it does not escape from the locking notch 5 of the adapter 4, and this holding piece 7 is located approximately at the center in the longitudinal direction. has a mounting portion 9 rotatably fitted into the mounting hole 8 of the mounting side wall 6 of the adapter 4, and extends from the mounting portion 9 toward the locking pin 2 in the locking notch 5. A plate-shaped wide rigid part 10 and a rod-shaped narrow elastic part 11 extending from the mounting part 9 in the opposite direction to the rigid part 10 are integrally molded and provided,
The extended end portion 11a of the elastic portion 11 is inserted into and latched into the latching hole 12 provided in the mounting side wall 6, and engaged with the protruding outer end of the latching pin 2 inserted into the latching notch 5. A locking pawl 13 is provided at the free end of the rigid portion 10.

(Function) According to the present invention, the linear holding piece 7 is integrally provided with the rigid portion 10 that has resistance to bending force and the elastic portion that can be elastically deformed by the bending force, and the rigid portion is provided with a locking claw. 13, a rigid part and an elastic part 1
1 is rotatably fitted to the side wall 6, the extension end 11a of the elastic portion 11 is fixed to the side wall 6, and when the holding piece 7 is in a straight state, as shown in FIG. The locking pawl 13 is engaged with the locking pin 2 to hold the pin in the locking notch 5.

Therefore, the coin selector 3 is connected to the adapter 4.
When the locking claw 13 is attached to and detached from the locking notch 5, the locking pin 2 is inserted into the locking notch 5 as shown in FIG.
in the closed position that prevents the insertion of the
As shown in the figure, the rigid portion 11 is rotated about the mounting portion 9, and the locking pin 2 is inserted into the locking notch 5.
The locking pawl 13 is moved to the open position which allows insertion or removal of the locking pawl 13.

At this time, the elastic portion 11 is as shown in FIG.
It is elastically deformed between the attachment portion 9 and the extension end 11a, and elastic restoring force is stored therein.

In this way, in order for the locking pin 2 to come out of the locking notch 5, it is necessary to apply a force sufficient to elastically deform the elastic portion 11, and therefore, it is necessary to apply a force sufficient to elastically deform the elastic portion 11. Therefore, it is possible to reliably prevent the coin selector 3 from escaping from the adapter 4.

(Embodiment) FIG. 1 shows an embodiment of the present invention, and the illustrated example includes a coin selector 3 that is detachably fitted between the left and right mounting side walls 6 of a groove-shaped adapter 4. In the illustrated mounting position, the locking pins 2 protruding from both sides 1 of the coin selector 3 are inserted into the L-shaped notches 5 of the mounting side walls 6 of the adapter 4, and are rotated by the mounting portions 9 on the side walls 6 of the adapter 4. The locking pin 2 is elastically held against the side wall of the locking notch 5 by the locking pawl 13 of the holding piece 7, which is injection-molded from a synthetic resin material, and this allows the coin selector 3 to be removed from the adapter 4. It is held so that it does not fall off. The holding piece 7 is formed in a symmetrical shape so as to be compatible with the left and right side walls 6, and as shown in FIGS. The mounting portion 9 is formed of a cylindrical projection 9a projecting from the back side of the holder 8, and tabs 9b are provided projecting on both sides of the projection 9a. Further, a knob piece 14 is provided protruding from the front side of the rigid portion 10, a guide piece 15 is provided protruding from the back side, and a latching protrusion 16 is provided from the back side of the free end of the elastic portion 11.
is provided.

In order to attach the holder 7 having the above-described structure to the side wall 6, a groove 8a is provided in the hole 8 provided in the side wall 6 so that the cylindrical protrusion 9a with a lug can fit therein, and the cylindrical protrusion 9a with a lug is inserted into the groove. It is adapted to be rotatably fitted into the attachment hole 8 using a bayonet joint method.

Further, the locking notch 5 is provided with a slot portion 17 for guiding the guide piece 15.

(Effects of the invention) According to the invention, the holding piece can be manufactured at low cost by injection molding a synthetic resin material, and the holding piece integrally includes a pivot mounting part, a hooking part, and an elastic part. Assembling is easy because the pivot mounting part is simply attached to the adapter by fitting it into the adapter, and there is no need to tighten it with screws or adjust the mounting position.This reduces the manufacturing cost of the coin selector mounting device. There is an effect that it can be done.
