Abstract

PURPOSE: To prevent a hook from being easily detached without any expansion of a recess section and without any need of providing an additional part. CONSTITUTION: Both ends of a pin 21 are rotatably laid in a recess 8 formed at the corner 7 of a case 1, and a structure is so formed that the intermediate section of the pin 21 projects externally from the recess 8, when the pin 21 is turned to the side 1b of the case 1 about each end thereof. As a result, even when a hook 12 is fitted to the projected intermediate section of the pin 21 and turned about the pin 21 in a stretched state, the movable section 13 of the hook 12 becomes free from being pressed to the edge 8c of the recess 8 and does not open.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook mounting structure for small electronic equipment.

[0002]

2. Description of the Related Art Small electronic devices include pagers, pocket radios, and cassette recorders. In such a small electronic device, a strap having a hook at the tip is attached in order to carry the device well or prevent the device from being lost. Such a hook mounting structure will be described by taking a pager as an example. First, an outline of the pager will be described. A pager is a portable receiver that receives a ringing signal from a base station and notifies it by sound or vibration, and as shown in FIGS. 6 and 7,
The pager case 1 has a thin box shape. And
The case 1 is provided with a name plate 3, a main key 4, a speaker hole 5, an LED 6, and the like, in addition to a liquid crystal panel 2 for displaying a received message and the like.

Next, the hook mounting structure of the pager will be described together with the hook structure. The two side faces 1a of the case 1,
Each of the side surfaces 1a,
A recess 8 is formed which is open only in 1b. A pin (mounting member) 9 is mounted in the recess 8 in a recessed state without protruding outward. That is, the pins 9 are provided on the inner wall surfaces 8a and 8b of the recess 8 which face each other, with the respective end portions 9a and 9b thereof being embedded. In this case, the pin 9 is attached to an offset position in the recess 8, that is, at the back side of the recess 8 and near the lower side surface 1b in FIG. On the other hand, the hook 12 of the strap 11
Has an annular shape as a whole, and has a structure in which a part thereof has a movable portion 13 which rotates inward with a spring property. With this hook attachment structure, when attaching the hook 12 to the case 1, the hook 12 is inserted into the recess 8 and
The movable part 13 is pressed against the pin 9 in the recess 8. Then, the movable part 13 pivots inward against the spring force and opens, so that the pin 9 enters the inside of the hook 12, and when the pin 9 separates from the movable part 13 in this state, the movable part 13 is restored by the spring force. Return to. As a result, as shown in FIG.
Is attached.

[0004]

However, in the above-mentioned conventional hook mounting structure, since the hook 12 is mounted on the pin 9 mounted in the recess 8 in a state of being recessed, the case is pulled while the strap 11 is pulled. When it is moved along the side surface 1b of the hook 1, the hook 12 rotates around the pin 9 as shown in FIG.
The movable part 13 of the hook is pressed against the recess edge 8c, and the hook 12
There was a problem that it opened and came off from the pin 9.
As a method of avoiding this, it is conceivable to form the recess 8 wide so that the movable portion 13 of the hook 12 does not contact the recess edge 8c. However, this method is not preferable because the inside of the case 1 becomes narrower by the amount by which the recesses 8 are expanded, and the mounting density decreases, and further, when the shape of the recesses 8 becomes large, it is not preferable in terms of design. As another method, it is possible to attach a ring to the pin 9 and attach the hook 12 to this ring. However, this method is not preferable because the number of rings as the number of parts increases, which causes a cost increase, and the ring may damage the case 1 before shipping. An object of the present invention is to provide a hook mounting structure for a small electronic device capable of preventing the hook from easily coming off without expanding the recess and without requiring an additional part such as a ring. is there.

[0005]

According to the present invention, a recess is formed in the outer periphery of an equipment case, a mounting member is provided in the recess, and a hook having a movable portion is removably mounted in the mounting member. In the hook mounting structure of the device, a part of the mounting member provided in the recess is projected from the recess to the outside. In this case, as described in claim 2, it is desirable that the mounting member is accommodated in the recess so as to be retractable.

[0006]

According to the present invention, even if the hook attached to the attachment member is pulled to the outside of the equipment case and pivots around the attachment member, a part of the attachment member is removed from the inside of the recess to the outside of the equipment case. Since it protrudes in, the movable part of the hook is not pressed against the edge of the recess to open. In this case, as described in claim 2, if the mounting member is structured to be retractable in the recess, the mounting member is housed in the recess so that the mounting member can be hit or hooked to an object. Since the mounting member is not exposed from the device case, it is preferable in terms of design.
