Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device mounting structure for a column.

[Conventional technology]

A recent outdoor infrared detector (a crime detector that consists of a floodlight and a light receiver between which an intruder blocks the infrared beam) operates by blocking leaves from the leaves or birds. In order to prevent this from happening, two infrared beams are provided instead of one, and they are configured to operate when both of these two beams are blocked (this is called the W beam system).

The beam width is 20 even though it is a W-beam type infrared detector.
It was ~ 30cm, and it was possible to judge at a glance where the warning range was when the detector was exposed, and it was possible that an intruder could jump over or slip through. Therefore, where it is necessary to construct a wide warning range, as shown in FIG.
2 to 3 sets of W-beam infrared detectors A are stored in the self-supporting equipment storage case B, the warning range C ₁ is expanded to the warning range C _2, and the cylindrical outer casing of the self-supporting equipment storage case B is stored.
B ₂ was composed of an opaque resin (a resin that does not transmit visible light but transmits infrared light).

The free-standing instrument housing case B than those carrying the cylindrical shell B ₂ having an umbrella B ₁ at the top to the base B _3, the H-shaped steel shown in FIG. 5 erected on the inside on the base B ₃ There is a pillar 1. The infrared detector A was attached to the support 1 by the following method.

As shown in FIG. 5, the H-shaped steel column 1 has screw holes 11 provided at predetermined intervals, and the equipment mounting base 2 has elongated holes 21. An infrared detector A is attached to the equipment mount 2. Therefore, the mounting screw 22 is passed through the elongated hole 21 and tightened in the screw hole 11.

By the way, instead of round or square steel pipes, we used H-shaped steel for the columns, because H-shaped steel is strong and has a space that can be used for terminal block mounting, wiring, etc. Because there is. Round steel pipes can be installed using U-shaped bolts, etc., but in order to mount the terminal block, etc. on the column, the column surface is curved and cannot be directly mounted, so new mounting brackets for the terminal block, etc. The hollow part in the steel pipe becomes a wasted space. With square steel pipes, the terminal block, etc. can be easily attached to the columns, but the hollow space becomes wasted space.

However, with this mounting structure, although it was possible to loosen the mounting screw 22 that mounts the device mounting base 2 to the H-shaped steel column 1 and adjust the position of the infrared detector A in the vertical direction to some extent, To change it, you have to remove the mounting screw 22 one by one in the narrow part of the recess of the H-shaped steel column 1 while disturbing the projection of the optical system part A ₁ of the infrared detector A, and re-install it. During the work, the screws were often lost, which was a troublesome work. Further, when the infrared type detector A was mounted back to back in the recesses on both sides of the H-shaped steel column 1 at the same height position, the screw holes could not be mounted because they coincided with each other.

[Problems to be solved by the device]

As described above, in the conventional mounting structure, when an apparatus such as an infrared detector is mounted on the recesses on both sides of a support such as an H-shaped steel at the same height position back-to-back with a device mounting base, screw holes are required. Could not be installed in agreement. Also,
In order to install the equipment or change the installation position, it is necessary to tighten or remove the screws in a tight and tight space, and it is often a troublesome work to lose the screws during outdoor work. There was a problem to say.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to place a device at the same height position back to back in a columnar recess having parallel plate-like protruding edges such as H-shaped steel. It is possible to provide a device mounting structure that can be mounted on the device and can be easily installed and changed in a spacious space without losing screws.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention provides a device mounting base that can be loosely inserted between the plate-like protruding edges on a column having at least one pair of plate-like protruding edges that protrude in the same longitudinal direction and have a constant interval. At least a pair of support pieces that are attached to the device mounting base at a substantially right angle to both vertical sides of the device mounting base and that are parallel to the plate-like protruding edges and can be loosely inserted between the plate-like protruding edges. In addition, a sandwiching metal fitting is provided on the outside of each of the pair of support pieces, and the outside metal surface of each of the pair of plate-like protruding edges is pressed and sandwiched by the sandwiching metal fitting.

[Action]

With the above configuration, when the support pieces raised at substantially right angles to the vertical side edges of the device mounting base are loosely inserted between the plate-like protruding edges of the columns having the plate-like protruding edges whose intervals are constant,
Since the clip fittings provided on the outside of each of the support pieces pop out to the outer surface of each of the plate-like protruding edges, the clip fittings can be pressed and held by the outer surface of each of the plate-like protruding edges with a screw or the like. The device attached to the device mount can be attached to the column.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2, and another embodiment will be described with reference to FIG.

FIG. 1 shows an embodiment for mounting the infrared detector A. The point different from the conventional example is that the recess of the column 1 having parallel plate-like projecting edges 1a, 1b at a predetermined interval There is no threaded hole at a predetermined interval, and the equipment mounting base 2 is not provided with a long hole for screwing into the recess of the support column 1. Instead, the equipment mounting base 2 is raised at a substantially right angle on both vertical sides. The support piece 2a is provided with a screw hole 2b and two detent holes 2c at the tip of the support piece 2a. Then, the clip 3 is attached to the screw hole 2b at the tip of the support piece 2a by the clip screw 3c through the through hole 3b opened in the clip 3.

In order to sandwich the device mounting base 2 between the parallel plate-shaped protruding edges 1a of the support column 1 at a predetermined interval, the device mounting base 2 is loosely inserted between the parallel plate-shaped protruding edges 1a at desired positions. Then, the two plate-shaped projecting edges 1a enter between the support piece 2a and the sandwiching metal fitting 3 which are raised at substantially right angles to the vertical both sides of the equipment mounting base 2, and the plate-like projecting edge 1a is screwed on the pinch screw 3c. To contact. In this state, tighten the pinch screws 3c from both sides while turning. Then, the outer edge surfaces 1c and 1d of the respective plate-like protruding edges 1a are pressed by the respective sandwiching metal fittings 3, and the equipment mounting base 2 is sandwiched and fixed to the support column 1.

In addition, the two protrusions 3a provided on the clip 3 are the support pieces.
Since it fits into the two rotation stop holes 2c of 2a, even if the pinch screw 3c is turned and tightened, the pinch metal fitting 3 rotates together with the pinch screw 3c, and the pinch metal fitting 3 becomes the outer edge surfaces 1c and 1d of the plate-like protruding edge 1a. It can be firmly clamped and fixed without falling off.

FIG. 2 is a perspective view showing a state in which two infrared detectors A are attached back to back at the same height position of the recess of the column 1 by the method of FIG. Since the device mounting structure is sandwiched between the plate-shaped protruding edges 1a and 1b having parallel intervals, the devices can be mounted at the same height position without any trouble. In addition, the pinch screw 3c can be tightened and loosened by the driver D in a vacant space, and the pinch screw 3c can be freely slid in the direction of the arrow E only by loosening it without completely removing it.

FIG. 3 shows a different embodiment, which differs from FIG.
Support pieces raised at approximately right angles to both vertical sides of the equipment mount 2.
The tip of 2a is bent in a U shape, and a screw hole is formed in the outer piece of the bending.
2b is provided, and a pinch screw 3d as a pinch metal fitting is provided in this screw hole 2b.
Is provided.

To clamp the device mounting base 2 to which the infrared detector A is mounted on the parallel plate-shaped projecting edges 1a of the support 1 at predetermined intervals,
Loosen the pinch screw 3d so that it does not come off the screw hole 2b,
The device mounting base 2 is loosely inserted between the parallel plate-shaped projecting edges 1a at desired positions. Then, the U-shaped recesses of the support pieces 2a provided on both vertical sides of the equipment mounting base 2 are formed into the two plate-like protruding edges of the support column 1.
After applying all the way to 1a, tighten the pinch screws 3d on both sides and tighten, and the pinch screws 3d press the outer edge surfaces 1c and 1d of the plate-shaped protruding edges 1a, and the device mount 2 is clamped and fixed on the column 1. To do.

Therefore, also in this case, as in the case of FIG. 2, two infrared detectors A can be mounted back to back at the same height position of the recess of the column 1 without any trouble, and the infrared detector A can be sandwiched as a sandwich metal fitting in a space with a sufficient margin. The screw 3d can be tightened or loosened, and the pinch screw 3d can be freely slid in the direction of the arrow E only by loosening it without completely removing it.

[Effect of device]

Since the device mounting structure of the present invention is configured as described above, it is possible to mount the device between the plate-like projecting edges of the columns having the parallel plate-like projecting edges at predetermined intervals or change the device mounting position. It can be easily installed in a wide space, can be installed at any height, and without losing screws, the columns with parallel plate-like protruding edges with a certain interval have recesses on both sides, for example H-shaped steel. In the case of the column, there is an effect that it is possible to provide a device mounting structure in which two devices can be mounted back to back in the recesses on both sides of the column at the same height position.
