Description

The present invention relates to a housing suspension structure, and more particularly to a structure that reduces the area occupied by the housing suspension structure.

  It is important to reduce the area occupied by the housing suspension structure because the area around the housing can be used efficiently.

  There exists a thing described in patent document 1 as a structure which attaches a housing | casing to the base material attached to the wall surface.

  This patent document 1 shows a handset holding structure having a handset holder for holding a handset of a cordless telephone fixed to a wall surface with a screw and a handset mounted on the handset holder. .

  When this slave unit holding structure is diverted to a housing suspension structure that uses a suspension member to suspend a housing such as a vehicle-mounted speaker microphone, a slave unit holder is attached to the back of the slave unit. Therefore, it is considered possible to guide the following housing suspension structure.

  The housing used in the housing suspension structure is formed in a substantially rectangular parallelepiped shape, and a suspension member is screwed to the back surface of the housing. This suspension member is made of sheet metal, and has an extending portion that extends from a position that is screwed to the housing to a position that does not overlap the housing, and an opening is formed in the extending portion. It is. Further, the suspension base material is made of sheet metal and has an attachment portion attached to the wall surface and an extension portion extending from the attachment portion, and the extension portion is inserted into the opening of the suspension member. It is possible.

  With such a housing suspension structure, the extended portion of the suspension base material is passed through the opening of the suspension member, and the inner wall of the suspension member opening is supported by the extension portion of the suspension base material. By doing so, the housing can be detachably suspended from the suspension base material.

  However, in the case suspension structure diverted from the handset holding structure described in Patent Document 1, if there are obstacles in the direction in which the suspension member moves relative to the suspension base, It is necessary to prevent the surface of the casing from colliding with an obstacle when the suspension member is inverted and suspended from the suspension base material. As a result, the extending portion of the suspension base becomes longer or the suspension provided on the casing is arranged so that the portion in front of the suspension member by the thickness of the casing is separated from the obstacle. There is a problem that the area occupied by the housing suspension structure becomes large due to the length of the member.

  For example, in order to prevent the casing from being unnecessarily detached from the suspension base material, if the extension portion of the suspension base material is bent to form a bent portion, the suspension member is suspended from the bent portion. This eliminates the possibility that the housing will be unnecessarily detached from the suspension base material, but when the suspension member is suspended from the suspension base material, the front and back surfaces of the housing are reversed. There is a risk that the surface of the housing may be damaged by coming into contact with the protruding portion.

  In order to solve this problem by ordinary means, when the bent portion of the suspension base is set at a gentle angle and the suspension member is brought close to the suspension base, the surface of the housing is suspended. It is necessary to avoid contact with the bent portion. In this way, when the bent portion of the suspension base material is at a gentle angle, the suspension base material is pulled out to the front, and the area occupied by the suspension base material is expanded. On the other hand, even if an attempt is made to prevent the surface of the housing from being damaged by increasing the length of the suspension member, the suspension member becomes large and the area occupied by the housing suspension structure increases.

  In addition, when the wall surface to which the suspension base material is attached and the housing are arranged to face each other, if the housing is prevented from being damaged by the wall surface that is an obstacle, the housing suspension is similarly applied. There is a problem that the lowering structure becomes large.

Therefore, in the present invention, when there is an obstacle in the moving direction of the suspension member with respect to the suspension base material, the casing is suspended from the suspension base material with either the front surface or the back surface facing forward. Even so, it is an object to provide a small housing suspension structure that does not damage the front and back surfaces of the housing.

The present invention is provided with a suspension base having an attachment part attached to a wall surface and an extension part extending from the attachment part, and a suspension member suspended from the extension part of the suspension base. The suspension member is suspended so as to be movable in the extending direction of the suspension base material, and the suspension member is attached to the suspension base material. When suspended, the front surface and the back surface of the housing are arranged apart from each other in the moving direction, and the suspension member is provided at the approximate center of the width formed by the front surface and the back surface of the housing. It is the case suspension structure provided.

According to the present invention, the suspension member is provided in the housing at a substantially center of the width formed by the front surface and the back surface of the housing that are separated from each other in the moving direction of the suspension member with respect to the suspension base material. Even when either the front surface or the back surface of the housing is directed toward the obstacle, the housing can be suspended from a small suspension base material without being damaged.

Embodiment 1 FIG.
Hereinafter, the housing suspension structure according to the first embodiment will be described with reference to the drawings.
In FIG. 1, a speaker microphone (housing) 1 includes a display unit 2 and an operation unit 3 on the front side (front surface), a speaker 4 on the back side (back surface), and a microphone 5 on the upper surface. Therefore, the housing can be reduced in size as compared with the case where the function units such as the display unit 2 and the speaker 4 are arranged only on one surface of the speaker microphone 1. The hanging metal fitting (suspending base material) 6 is formed by bending a sheet metal and has at least a base surface portion (attachment portion) 6a fixed to the wall surface and an extending portion 20 extending from the base surface portion 6a. And fixed to the wall surface with screws 7 and 8. The extending portion 20 includes a portion bent downward from the bottom end of the base surface portion 6a and a portion (movement restricting portion) 21 bent further forward and upward. The hanging metal fitting (hanging member) 9 is a sheet metal projecting vertically from the upper part of the speaker microphone 1 and is arranged at substantially the center so that the front and back of the speaker microphone 1 can be hung at the same position. is doing.

This Θ ₁ = 20 degrees is the minimum angle with respect to the direction of gravity of the speaker microphone when a person hangs the speaker microphone by hand, and corresponds to the angle when the arm is lowered slightly from the overhead direction. In this embodiment, since the portion 21 bent upward in front of the extending portion of the hanging bracket 6 is formed with a rounded shape, the front side and the back side of the speaker microphone 1 do not collide with the portion 21. The structure can be formed with a smaller size. Furthermore, since the edge portion of the speaker microphone 1 is rounded, a structure in which the front side and the back side of the speaker microphone 1 do not collide with the portion 21 bent upward in front of the effect portion of the hanging metal fitting 6 has a smaller size. It can be formed.

With this configuration, the hanging bracket 9 is arranged substantially in the center, and the distance c is secured so that the speaker microphone 1 and the hanging bracket 6 do not come into contact when the tilt angle when hanging the speaker microphone is 20 degrees or more. Therefore, the speaker microphone 1 can be hung at the same position regardless of the front or back of the speaker microphone 1, and the speaker microphone can be prevented from being damaged.

Embodiment 2. FIG.
Hereinafter, the housing suspension structure according to the second embodiment will be described with reference to the drawings.
In FIG. 4, a speaker microphone 1 includes a display unit 2 and an operation unit 3 on the front side, a speaker 4 on the back side, and a microphone 5 on the upper surface. The hanging metal fitting 6 is formed by bending a sheet metal, has at least a base surface portion 6 a fixed to the wall surface, and an extension portion 20, and is fixed to the wall surface by screws 7 and 8.

The protrusions 9d and 9e of the hanging metal fittings are respectively fitted. When the hanging metal fitting is rotated from this state, since the recesses 16a and 16b and the projections 9d and 9e are dome-shaped, the rotational force changes to a pressing force at the contact portion between the recess and the projection when the projection is removed from the recess. The spring gradually shrinks and the metal fitting 9 is pushed down. However, since the hanging bracket cannot be rotated with a rotational force whose pressing force is smaller than the reaction force of the spring 15, it is in a semi-locked state where it cannot be easily rotated.

FIG. 6B shows a state 2 in which the hook 9 is unlocked every 180 degrees and the hook 9 can freely rotate. In this state, the projections 9d and 9e are completely removed from the recesses 16a and 16b, and the hanging bracket 9 is pushed down. When further rotated and rotated from the original position to a position of exactly 180 degrees, the protrusions 9d and 9e are fitted into the recesses 16b and 16a, respectively, and are again in a semi-locked state.

With this configuration, when the speaker microphone is hung, the hanging surface of the hanging bracket 9 is always arranged on the wall side so that the speaker microphone 1 and the hanging bracket 6 are not in contact with each other. Even before, it can be hung at the same position and the speaker microphone can be prevented from being damaged.
