Description

[Detailed Description of the Invention] The present invention relates to a mounting bracket used when installing communication equipment on the ceiling of a vehicle.

In radio communications on trains, etc., when radio equipment is mounted on the vehicle side, it is often mounted on the ceiling due to space constraints. As shown in Fig. 1, a method for installing such a radio is to fix a mounting bracket 2 on a ceiling 1, which has a pin guide 2a at the rear of both side panels and a threaded section 2b at the front. As shown in Figure 2, the pins 3a protruding from the rear of both sides of the radio 3 are fitted into the pin guide 2a, and the fixing screws 4 arranged at the front of the radio 3 are screwed into the threaded portions 2b. Therefore, the radio device 3 is firmly attached and fixed to the mounting bracket 2.

However, since the pin guide 2a of the conventional mounting bracket 2 is formed with a horizontal notch as shown in the figure, when the radio 3 is removed for maintenance and inspection, the fixing screw 4 is removed as shown in FIG. If the guide pin 3a was removed, the guide pin 3a would slip within the guide 2a, and there was a risk that the radio device 3 would fall due to slight adjustment.

Therefore, a mounting bracket as shown in FIG. 4 was provided. In this mounting bracket 12, a protrusion 12c is provided near the open end of the pin guide 12a, and a locking portion 12d for the guide pin 13a is formed at the back of the protrusion 12c. Therefore, as shown by the chain line in FIG. 4, even if the fixing screw 14 is removed, the guide pin 13a is restrained within the locking portion 12d, and the radio device 13 can be prevented from falling. In addition, when this mounting bracket 12 is adopted, the method for attaching the radio 13 is to first hold the guide pin 13a on the locking portion 12d of the pin guide 12a by climbing over the protrusion 12c, and then
is rotated to screw the fixing screw 14 into the threaded portion 12b.

However, in the above-mentioned mounting bracket 12, the locking portion 12d of the guide pin 13a is formed one step below the protrusion 12c, and since the above-described mounting method is used, the ceiling 11 due to the rotation of the radio 13 is In consideration of the _clearance between It had already occurred.

The present invention was made with the aim of eliminating the above-mentioned problems, and the guide of the mounting bracket is formed diagonally downward as it goes deeper from the opening end of the guide, and then is formed diagonally upwardly. To provide a communication device mounting bracket that prevents the communication device from falling and eliminates a large gap between the device and the object to be attached when the device is installed.

The present invention will be described in detail below based on one embodiment of the accompanying drawings.

In FIG. 6, the communication device mounting bracket 20 is bent into a substantially U-shape, and guides 20c are formed at the rear portions of opposing side panels 20a, respectively. This guide 20c has a descending portion 20c ₁ that is inclined obliquely downward with respect to the upper surface plate 20b, and a rising portion 20c ₂ that is continuous with this descending portion 20c ₁ and is inclined obliquely upward relative to the upper surface plate 20b. ing. Furthermore, a fixing portion, for example, a threaded portion 20d, is formed at the front portion of both side plates 20a of the mounting bracket 20. The mounting bracket 20 having such a shape is integrally formed with a single metal plate.

Then, the mounting bracket 20 is installed horizontally on the ceiling 1 of a train, etc.
The top plate 20b is firmly fixed with screws (not shown). Therefore, in such a mounting state, each inclined portion 20 of the guide 20c of the mounting bracket 20
c ₁ and 20c ₂ are inclined with respect to the horizontal direction. Next, the guide pin 3a of the communication device, for example, the radio device 3 shown in FIG. 1, is attached to the mounting bracket 2 as shown in FIG.
0 into the guide 20c, push the radio 3 horizontally backward and insert it into the mounting bracket 20, and screw the fixing screw 4 into the threaded portion 20d to fix the radio 3 to the mounting bracket 20.

In this state, the radio 3 has a guide pin 3a.
is the highest position 20 of the rising part 20c ₂ of the guide 20c
It is locked at c ₃ and is fixed to the ceiling 1 with almost no gaps.

When removing the radio device 3 from the mounting bracket 20 for maintenance, inspection, repair, or the like, the above-described installation procedure may be reversed. At this time, when the fixing screw 4 is removed, the guide pin 3a slides down the rising part _20c2 due to the weight of the radio 3, and moves to between the rising part _20c2 and the descending part _20c1 . In other words, radio 3
The front surface of the radio device 3 is pushed out a certain distance from the mounting bracket 20, so that the radio device 3 can be easily removed. Further, even if the hand supporting the radio 3 comes off after removing the fixing screw 4, if the guide pin 3a is hooked on the guide 20c, the guide pin 3a will be connected to the descending part 20c ₁ of the guide 20c. Since the radio device 3 is held between the rising part 20c2 and the ceiling ₁ , the radio device 3 rotates around the guide pin 3a as shown by the chain line in FIG. It can prevent falling.

As explained above, according to the present invention, although it has an extremely simple structure, it is possible to effectively prevent the communication device from falling from the mounting bracket, improve safety when removing it, and Workability during removal can also be improved.
Furthermore, when the communication device is attached, the communication device can be brought into close contact with the object to which it is attached, so that space saving can be improved.
