Description

[Detailed Description of the Invention] The present invention relates to a hook attachment device for hanging, for example, a watch hanger.

Conventionally, for example, the outer case of a thin portable watch houses an inner case that incorporates the watch mechanism and is fixed with screws. A hook is attached to hang it. For this reason, the work of attaching the hook and the work of fixing the inner case are separate processes, which has the disadvantage of increasing the number of processes. Another drawback was that the screws for fixing the inner case were exposed on the outer surface of the outer case, spoiling its appearance.

The object of the present invention is to eliminate the above-mentioned drawbacks by providing a hook attachment device that also serves as attachment of the inner case.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a small and thin outer case, which is illustrated as a watch case in the drawings. The outer case 1 is formed into a cylindrical shape, with one side (left side in FIG. 1) serving as a side wall 1a, and the other side serving as an opening 1b sealed by a side plate 2. The outer case 1 houses a plate-shaped inner case 3 in which a mechanical body (not shown) is incorporated. The inner case 3 is slid into the outer case 1 through the opening 1b. Reference numeral 4 denotes a middle case mounting screw, which passes through a hook mounting hole 1c provided in the side wall 1a, and a flange portion 5 for fixing the middle case is attached to the inner end of this screw (right end in Figure 2). are provided integrally. The flange portion 5 is installed in a groove portion 3a provided in the middle case 3 facing the hook attachment hole 1c in a direction perpendicular to the surface of the middle case (a second
(perpendicular to the plane of the drawing). The flange portion 5 has stepped portions 3b, 3b provided in the groove portion 3a.
It is housed on the side wall 1a side so as not to be able to escape.

The outer end of the head of the mounting screw 4 projects outward from the mounting hole 1c, and a threaded portion 4 is carved on the outer periphery of the projecting end.
A nut 6, which is a stopper for fixing the inner case, is attached to the inner case 3 to fix the inner case 3 to the outer case.

In addition, a shaft hole 4b provided at the shaft center of the inner case mounting screw 4 has a shaft rod 8 with a hook 7 at its tip.
The inner end of the shaft protrudes from the flange portion 5, and a retaining ring 9 such as an E-ring is attached to the protruding end to prevent the hook 7 from coming off. The hook 7 is located outside the outer end of the mounting screw 4 and has a latching hole 7a for latching a hanger.

Next, I will explain how to assemble the mounting device.
Assemble the inner case mounting screw 4, shaft rod 8, and retaining ring 9 in advance, and after storing the flange portion 5 of the mounting screw in the groove 3a of the middle case 3 as shown by the chain line in Fig. 2, remove the middle case. When the hook 7 and the head of the mounting screw 4 are slid in the direction of the arrow from the opening 1b of the outer case 1, the hook 7 and the head of the mounting screw 4 pass through the hook mounting hole 1c of the outer case and protrude out of the case. Then, for installation, by attaching a nut 6 to the outer end of the head of the screw 4 and tightening it, the inner case 3 can be fixed to the outer case 1 with the nut 6 and the flange part 5, and at the same time, a rotatable hook can be attached. Can be done. Note that after that, the opening 1b of the outer case 1
is sealed with a side plate 2, and the side plate is fixed to the side surface of the inner case 3 with screws or the like.

According to the mounting device configured in this way, by tightening the nut 6 screwed into the inner case mounting screw 4, the flange portion 5 is attached at the same time as the hook 7 is attached.
The inner case 2 can be fixed to the outer case with the nuts 6 and 6, making the work easy.

FIG. 3 shows another embodiment of the hook attachment device. According to this, the bridge-shaped inner case fixing stopper 10 is dropped into the groove 3c having the stepped portion 3b provided in the inner case 3 from a direction perpendicular to the surface of the inner case, and escapes to the side wall 1a of the outer case. It's impossible to fit in. In this fastener 10, a threaded portion 11a at the inner end of an inner case mounting screw 11 passing through a hook mounting hole 1c of the outer case 1 is screwed into a screw hole 10a of the fastener. The head of the mounting screw 11 is provided with a slotted or hexagonal flange portion 12 for fixing the inner case 3 to the outer case 1. Shaft hole 11b of middle case mounting screw 11
A shaft rod 8 having a hook 7 at its tip is rotatably inserted through the shaft, and a retaining ring 9 prevents it from coming off.

To assemble this mounting device, the inner case mounting screw 11 and the shaft rod 8 are connected in advance with a retaining ring 9. Therefore, first, the third
When the stopper 10 is housed as shown by the chain line in the figure, and then the inner case is slid inside the outer case 1 in the direction of the arrow, the hook attachment hole 1c faces the screw hole 10a of the stopper 10. Then, insert the inner case mounting screw 11 connected as described above through the mounting hole 1a of the outer case 1, turn the flange portion 12 with an appropriate tool such as a screwdriver, and screw the threaded portion 11a into the stopper 10.
Just screw it into the screw hole 10a. As a result, the inner case 3 can be attached to the outer case 1 using the stopper 10 and the flange portion 12, and at the same time, a rotatable hook can be attached.

The structure of the outer case 1 does not need to be cylindrical, but if it has this shape, the inner case 1 has the above-mentioned first shape.
In the example, the hook 7 and the mounting screw 4 are
In the example, with the stopper 10 attached, the inner case can be inserted from the side of the outer case, making assembly extremely simple.

As described above, according to the present invention, since the middle case can be attached at the same time as the hook, the process of attaching the middle case itself can be omitted and the work efficiency of assembly can be improved. Since there is no need to use screws for mounting, the appearance does not deteriorate as in the conventional case, and it is suitable for practical use.
