Description

[Detailed description of the invention] (Technical field to which the invention pertains) The present invention relates to the improvement of a chain holder used in small portable receivers, particularly individual paging receivers (hereinafter abbreviated as receivers), such as pocket bells. It is.

(Prior Art) FIGS. 4 to 8 are explanatory diagrams of conventional chain holding fittings, and FIG. 4 is a perspective view showing how the chain holding fitting is attached to a receiver. 1 in the figure is a receiver, to which a chain holding fitting 2 is attached. A chain 3 is attached to the hole of this holding fitting 2 via a double ring 3a, and a stopper fitting 3b is attached to the other end of the chain 3. A person holding (using) the receiver 1 puts the receiver in a chest pocket or the like, and clips the stopper 3b to the fabric of the chest pocket to prevent the receiver from falling out of the pocket. In this way, the chain retainer 2
is used to connect the receiver 1 and the chain 3 with a stopper.

FIG. 5 is a perspective view of the double ring 3a attached to the chain holding fitting 2. FIG. 6 shows a plan view A, an installation side view B, and a front view C in a direction perpendicular thereto, of the chain holding fitting 2.

FIGS. 7 and 8 are drawings for explaining the drawbacks of the conventional chain retainer. In Figure 7, the chain retainer 2
As shown in the front view B, there is a chain holding hole 2a in the center part, and as shown in the side view A, there is a chain holding hole 2a.
The figure shows a state in which the double ring 3a is opened and the chain holding fitting 2 is slightly held at the periphery of the double ring.
From this state, push up the double ring 3a further in the direction of arrow P until it reaches the center of the hole 2a.
If a is rotated with the direction changed by 90 degrees, the double ring 3a will pass through the chain holding fitting hole 2a and be attached to the chain holding fitting 2 as shown in FIG. 4.

However, when the state shown in Fig. 7 is reached, the double ring 3a
If the direction of the force pushing up the chain is deviated from the center direction of the hole 2a, the double ring 3a will easily slip because the peripheral edge of the chain holding fitting 2 is circular, and as shown in an example in FIG. will come off from the chain holding fitting 2, and it will be necessary to return it to the state shown in FIG. 7 and push it up again. As described above, the disadvantage of installing a double ring is that it is difficult to work with and requires skill and skill on the part of the operator.

(Specific purpose of the invention) The purpose of this invention is to improve the poor workability, which is a drawback of conventional chain holding fittings. (1) When attaching a double ring to a chain holding fitting, (2) No skill is required for installation work.

(Structure and operation of the invention) Figure 1 shows an example of the structure of the chain holding fitting according to the invention, and shows a plan view A, a side view B, and a front view C when the chain holding fitting 20 is attached to the case of the receiver 1. It shows. As shown in front view C, the chain holder 20 has a chain holder hole 20a in its center, which is the same as the conventional chain holder, but the chain holder 20 is characterized by having a straight portion 20b at its tip. be.
This becomes clear when compared with the conventional chain holding fitting 2 shown in FIGS. 5 to 8, which has a semicircular tip.

FIG. 2 is an explanatory diagram when the chain holding fitting 20 according to the present invention is used in combination with the double ring 3a. It has been confirmed that the relationship L>13R with respect to the radius R of the double ring 3a is sufficient.

Next, the procedure for attaching the double ring to the chain holder will be explained with reference to FIGS. 2 and 3. FIG. 2 shows a state in which the double ring 3a is opened and the chain holding fitting 20 is slightly held at the periphery of the double ring, and A is a side view and B is a front view. After pushing the double ring 3a further in the D direction from the state shown in Fig. 2, push the double ring tip 3a' up to the center of the chain holding fitting hole 20a as shown in the perspective view of Fig. 3, and rotate it at 90 degrees. When the double ring 3a is rotated in the E direction with the angle changed, the double ring 3a is attached to the chain holding fitting 20 (referred to as fitting), and this condition is the same as the conventional one shown in FIG. 4. As shown in FIG. 2B, the chain holding fitting 20 has a straight end 20b, so even if a force in the direction D is applied away from the center, the double ring 3a will not deviate from the straight end 20b. , it is possible to reliably move to the state shown in FIG. 3, and attachment of the double ring 3a to the metal fitting 20 is much easier and more reliable than in the past.

(Effects of the invention) By implementing the invention, it becomes easier to attach a chain with a stopper to a chain holding fitting used in a small portable receiver such as a pager. The drawback of poor workability has been resolved.
