Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to an attachment mechanism for attaching a relatively small wireless device to a shelf board, automobile dashboard, or the like.

Conventional technology When installing a small wireless device on a shelf board or the underside of a car's dash board, the horizontal piece of a downward U-shaped mounting bracket is fixed to the bottom surface of the shelf board, etc. At the same time, the left and right side pieces and the left and right side walls of the wireless device were respectively fixed with set screws.

Problems to be Solved by the Invention By the way, according to the above-mentioned configuration, screw holes are formed in the side wall of the wireless device, which spoils the appearance and makes it difficult to place the wireless device in the front-rear direction with respect to the mounting bracket or shelf board. Adjustment is not possible; for example, when the wireless device is mounted on a shelf or other side, it is extremely difficult to tighten screws on that side; when the height dimensions of the wireless device are different; The reason for this is that mounting brackets with short side heights cannot be shared, and when the height of the wireless device is large, the side height of the mounting member will also be long, so when the wireless device is removed from the mounting bracket, There were defects such as the side pieces of the mounting bracket protruding downward and getting in the way.

Means for Solving Problems The present application solves the above-mentioned defects of the conventional device, and its gist is that it has a downward U-shape, and the horizontal pieces are attached to the left and right side pieces of the mounting bracket that is fixed to a shelf, etc. , an inclination adjustment part consisting of a plurality of locking strips that locks with the upper edge of a locking piece formed on the upper surface of the outer casing of the wireless device, and a shaft rod passes through the one side piece, and one end thereof is provided. is fixed to the other side piece, and
A threaded portion is provided at a position outward from the one side piece, and a rotating piece that presses the one side piece inward is screwed into this threaded portion.

Effects and Examples Fig. 1 is a front view of a state in which a wireless device B is attached to a shelf board A via the attachment mechanism of the present application, and the attachment fitting 1 is made by bending a band-shaped metal plate into a downward U-shape. The horizontal piece 1a is provided with a long hole 3 for attachment extending in the longitudinal direction, which is attached to the lower surface of the shelf board A by a set screw 2, and the left and right side pieces 1b and 1c are
The lower outer surface is provided with an inclination adjusting portion 7 having a horizontal thin locking strip 4 extending in the width direction and a plurality of thin locking strips 5 and 6 intersecting with the horizontal thin locking strips 5 and 6 tilting forward and backward. A receiving rib 8 projecting outward is provided at the center of the lower edge.

A shaft rod 9 passes through the one side piece 1b, one end of which is fixed to the other side piece 1c, and a threaded part 10 is provided outward from the position of the one side piece 1b. A rotating piece 11 that presses the one side piece 1b inward is screwed together.

The wireless device B shown in the embodiment of the present application is a known wireless device that has a heat dissipation blade b extending in the front-rear direction on the upper surface of the outer casing, and the inner surface of the heat dissipation wing located at the outermost position is formed in a concave shape. Figure 1 shows the case where this concave heat dissipation wing is used as the locking piece b', but if the radio equipment does not have this concave heat dissipation wing, there will be a groove extending in the front and back direction on the left and right positions of the upper surface of the outer casing. A locking piece b' having a key-shaped cross section as shown in FIG. 3 is newly formed.

Therefore, in use, the horizontal piece 1a of the mounting bracket 1 is fixed to the lower surface of the shelf board A with the set screw 2, and one side piece 1b of the mounting bracket 1 is pressed by rotating the rotating piece 11. Then, left and right side piece 1b.1
Adjust the distance c so that it becomes slightly narrower than the inner pitch of the locking piece b'.

In this state, while adjusting the front and rear positions of the shelf A and the mounting bracket 1, the upper edges of the pair of left and right locking pieces b'.b' of the wireless device B are fixed to the left and right side pieces 1b of the mounting bracket 1. 1c to face the inclination adjustment parts 7.7, respectively, and then rotate the rotary piece 11 again to expand the left and right side pieces 1b.1c outward to the upper edges of the locking pieces b'.b'. At the same time, the upper edge is attached to any of the locking strips 4 to 6.
to set the inclination of the wireless device B with respect to the mounting bracket 1.

In order to expand the outer sides of the left and right side pieces 1b and 1c in the above, the left and right side pieces 1b and 1c of the mounting bracket 1 are slightly inclined outward respectively in advance, and the rotating piece 11 is rotated to extend the left and right side pieces 1b and 1c to one side. By pressing the side pieces 1b, the distance between the left and right side pieces 1b and 1c is narrowed, and then the rotating piece 11 is rotated in the loosening direction, using the restoring elasticity of the left and right side pieces 1b, 1c. It is something.

In addition, although the above example illustrates the case where the linear locking lines 4 to 6 are formed by convex lines, it is noted that they may also be formed by concave lines as shown in FIG. Although the case is shown in which the wireless device B has the locking piece b' in the direction, when the outer surface of the locking piece b' is formed in a concave shape or a key shape, the inclination adjustment part 7 is fixed to the mounting bracket 1. is formed on the inner surface of the left and right side pieces 1b.1c,
In this case, by pressing the left and right side pieces 1b and 1c inward by the rotation of the rotating piece 11, the locking strips 4 to 6
The leading edge of the locking piece b' is locked with the front edge of the locking piece b'. Further, when the locking strips 4 to 6 and the leading edge of the locking piece b' are disengaged, the locking piece b' locks with the receiving rib 8,
To prevent the wireless device B from falling off the mounting bracket 1.

Effects of the Invention As described above, according to the present application, since the operation for changing the interval between the left and right side pieces of the mounting bracket is performed on one side of the mounting bracket, the wireless device is shifted toward one side of the shelf board, for example. It is convenient to use and handle, and the direction of the operating part can be freely selected, and the mounting position and inclination of the wireless device in the front and rear directions relative to the shelf board can be adjusted, making it convenient for use and handling. The mounting brackets can be shared regardless of the size, and the left and right side pieces only need to be short in length.
This has the advantage that there is no fear that the mounting bracket will get in the way when the wireless device is removed.
