SUMMARY OF THE INVENTION Conventional equipment mounting device 1
01 is that the urging member 104 clamps the rail member 20 between the rail engaging portion 103a and the pressing portion 104a by the urging force of the leaf spring, so that the fixing force of the device mounting device 101 is reduced. There is a possibility that a predetermined pressing force cannot be obtained due to a decrease.

The rail member 2 of the equipment mounting device 101
Adjustment of the magnitude of the fixing force to zero tends to require labor and cost for adjusting the leaf spring of the biasing member 104. Further, the range of the fixing force that can be adjusted by the shapes of the urging member 104 and the engagement portion 103 is small, and the device mounting device 101
Has a small degree of freedom in setting the magnitude of the fixing force with respect to the rail member 20, and improvement in convenience is desired.

Further, the device mounting device 101 includes an urging member 1.
04 is fixed on the rail member 20 by directly using the elastic action of the pressing portion 104a bent at the center, that is, the biasing member 104.
Is pressed by the second flange portion 20b of the rail member 20.
It is necessary to position with high precision at a position where it can be engaged and pressed, and it is necessary to firmly fix the mounting portion between the urging member 104 and the frame 102 by so-called crimping. Therefore, despite the relatively simple configuration of the device mounting device 101, the labor and cost required for manufacturing are relatively large, and it is desired to improve the production efficiency and the manufacturing cost. I have.

In the frame of FIG. 4, a part is broken for convenience of explanation.

First, various devices (not shown) such as a switching power supply are mounted and mounted on the device mounting portion 2a of the device mounting device 1. Next, as shown in FIG.
The first flange portion 20a of the rail member 20 fixed above is inserted between the projection 3a of the holding portion 3 and the tongue piece 3b (gap d). At this time, the first flange portion 20a of the rail member 20
Is a tongue piece 3 inclined at a predetermined angle with respect to the frame 2
The first flange portion 20a is inserted along the inclined portion 3d of FIG. 2b, the distal end portion of the first flange portion 20a is located below the protrusion 3a, and the first flange portion 20a is held in a state of being engaged with the protrusion 3a. When the pressing mechanism 4 is rotated in the direction of arrow P with the protrusion 3a as a fulcrum from this state, the first flange 2 of the rail member 20 is moved from the protrusion 3a.
0a, a pressing force (referred to as a first force) acts in the direction of the arrow m, from the tongue piece 3b to the first flange 20a of the rail member 20 based on the elasticity of the tongue piece 3b. A pressing force (referred to as a second force) acts in the direction of arrow n.

On the other hand, the second flange portion 20b of the rail member 20
Is in sliding contact with the slope portion 5f of the engagement portion 5a. When the slide plate 5 is rotated in the direction of arrow P by further applying a predetermined force from this state, the slide plate 5 is biased by a biasing member (for example, a helical spring)
6 moves in the direction opposite to the biasing direction (the direction in which the second flange portion 20b is pressed) against the elastic force of the second elastic member 6. When the second flange portion 20b of the rail member 20 slides on the slope portion 5f and engages with the flat portion 5e of the engagement portion 5a, the slide plate 5
Moves in the biasing direction (the direction of pressing the second flange portion 20b) based on the elastic force of the biasing member 6, and moves downward from the engagement portion 5a to the second flange portion 20b of the rail member 20. The pressing force acts from.

Accordingly, as shown in FIG. 4 (b), the equipment mounting device 1
The first force acting on the first flange portion 20a from the protrusion 3a of the holding portion 3 and the second force acting on the first flange portion 20a from the tongue piece portion 3b cause the first force. The rail 20 is fixed by applying a force in a direction of sandwiching the flange 20a from both sides, and a push that acts on the second flange 20b from the engaging portion 5a of the pressing mechanism 4 on the other end of the rail member 20. Due to the pressure, the rail member 20 is fixed between the engaging portion 5a and the holding portion 3 while being held therebetween.

In the state where the device mounting device 1 is mounted on the rail member 20, even if a force larger than the pressing force of the pressing mechanism 4 and the holding force of the holding portion 3 is applied upward, the device mounting device 1 is still mounted. , The second flange portion 20b is the contact portion 1
It is held in contact with 5d, and does not fall off from the rail member 20a.

To remove the equipment mounting device 1 fixed on the rail member 20, a flathead screwdriver or the like is inserted into the release hole 5d, and a force is applied downward to push the slide plate 5 to the urging member 6. Is moved downward against the elastic force of the rail member 20, and the second flange portion 20b of the rail member 20 and the engagement portion 5a
Release the engagement with. Then, when the pressing mechanism 4 side is rotated in the opposite direction to the arrow P (see FIG. 4A) with the protrusion 3a of the holding portion 3 as a fulcrum, the first flange portion 20 of the rail member 20 is rotated.
a can be released from engagement with the holding portion 3, and the device mounting device 1 can be easily removed.

That is, the equipment mounting device 1 includes a holding portion 3 for applying a force in a direction of holding one end (first flange portion 20a) of the rail member 20, and a second end (second connection portion) of the rail member 20.
And the pressing mechanism 4 for pressing the flange portion 20b), the fixing force to the rail member 20 is large, and it can be detachably and firmly fixed to any position on the rail member 20. The fixing force of the holding portion 3 to the rail member 20, that is, the magnitude of the force of the holding portion 3 holding the first flange portion 20a of the rail member 20 is determined by the length L of the tongue piece 3b.
And the width W (illustrated in FIG. 2 (a)) can be arbitrarily changed according to the size thereof, so that the range of the adjustable fixing force is wide,
Moreover, it can be easily adjusted.

The pressing force of the pressing mechanism 4 against the rail member 20 is also adjusted by the urging member 6 having a predetermined elastic force.
Can be easily adjusted to an arbitrary size, and the equipment mounting apparatus 1 has a high degree of freedom in setting a fixing force to the rail member 20.

Further, the pressing mechanism 4 provided in the equipment mounting device 1
Is a configuration in which a pressing force based on the elasticity of the urging member 6 is indirectly applied to the rail member 20 via the slide plate 5 and the engaging portion 5a, and the displacement amount of the urging member 6 is large. Therefore, the engaging portion 5a can be provided without strictly adjusting the position of the slide plate 5 itself as a sliding member.
Thus, a predetermined pressing force can be applied to the rail member 20. That is, the device mounting apparatus 1 according to the present invention.
Is a pressing portion 104 integrally formed on the urging member 104.
In order to directly use the urging force of the conventional device mounting apparatus 10, it is necessary to position the urging member 104 with high precision.
1 (see FIGS. 5 to 7), the processing is easier,
Improvement in production efficiency and reduction in production cost can be achieved.

[0040]

As described above, according to the device mounting apparatus of the present invention, various devices can be detachably and firmly fixed to any position on a rail member fixed to a wall or the like, and the fixing force can be secured. The degree of freedom of setting is large, and it is possible to achieve an improvement in production efficiency and a reduction in manufacturing cost.
