Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a mounting bracket, for example, a mounting bracket used when attaching a ballast box or the like to a ceiling bolt.

(Prior Art) In recent years, buildings have been installed with many ducts, wiring, etc. for various facilities, and beams have become larger, so the ceiling space has become smaller. Therefore, with these changes in buildings, lighting fixtures and the like must be made ultra-thin as shown in FIG. 8 to be used as recessed types.

In order to create an ultra-thin lighting fixture, a separate ballast must be installed.
The ballast box must be installed separately in place.

For example, as shown in FIG. 8, in the conventional recessed lighting fixture 1, an opening 3 for the lighting fixture is formed in the ceiling 2 after finishing the ceiling 2, and the lighting fixture is fitted into the opening 3. If there was a duct or beam 4 above the opening, the stabilizer was removed to make it ultra-thin. This ballast was housed in a newly manufactured ballast box 5, and the ballast box 5 was suspended in the attic by anchor bolts 7 newly driven into the slab 6. In addition, in FIG. 8, the reference numeral 8 indicates a hanging bolt for ceiling installation.

(Problems to be Solved by the Invention) As mentioned above, in the conventional lighting fixture installation structure, when installing a ballast separately, climb up to the ceiling and drill a hole in the slab 6, and insert the anchor bolt 7 into this hole. Since the box 5 containing the stabilizer is attached to the anchor bolt 7 with nuts, it is very troublesome and difficult to work in the narrow space behind the ceiling, and the material of the ceiling 2 is not very strong. Since the ballast box 5 was not available, the work had to be done with great care.Therefore, a metal fitting that would allow the ballast box 5 to be attached to an existing hanging bolt was desired.

By the way, it does not involve installing a ballast box, but
As a type of mounting bracket, one disclosed in Japanese Utility Model Application Publication No. 56-144423 is known.

The lighting equipment hanging device of the invention disclosed in this publication connects the lighting equipment body to an anchor bolt when hanging the lighting equipment body from the ceiling with a hanging wire. Holes for wire insertion are formed in each encyclopedia surface.

However, such a conventional suspension device cannot be freely attached or detached unless at least one end of the wire or rod-shaped body to which it is attached is a free end.

Therefore, for example, as shown in FIG.
The conventional hanging device is applied to a rod-shaped body that is connected to something at both ends, such as a hanging bolt 8 for ceiling installation, which is driven into a ceiling mounting bolt 6 and the other end holds a ceiling mounting material. I couldn't do that.

An object of the present invention is to provide a mounting bracket that can be mounted in the middle of a rod-shaped body in a so-called one-button manner to support an object to be mounted.

(Means for Solving the Problems) The present invention provides a mounting bracket for attaching an object to be mounted between the two stoppers of a bar-shaped body having at least two spaced apart stoppers, the mounting bracket comprising: A spring plate-like member whose one end is completely fixed to the object to be attached and whose other end extends outward from the object, and when the plate-like member is curved, a cutting hole for fitting the rod-like object is provided on the curved surface of the plate-like member. A long hole is formed along the longitudinal direction of the plate member to form a groove.

(Function) According to the mounting bracket of the present invention, the mounting bracket is made of a spring plate-like member that has one end fixed to the object to be attached and the other end is a free end, and is curved so that both ends are close to each other. The rod-shaped body is inserted into the cut groove formed by the long hole that appears on the surface. At this time, this curved fitting is mounted between two stoppers formed at intervals in the longitudinal direction of the rod-shaped body. When the rod-like body is relatively fitted to the position where the rod-like body abuts the deepest part of the cut groove, that is, both ends of the elongated hole, the force applied to the fitting to curve it is released. As a result, the mounting bracket opens in an attempt to return to its original straight shape due to the restoring force due to its spring properties, but both ends of the elongated hole are still held in contact with the stopper of the rod-shaped body, preventing its return to opening. The restoring force acts as a fixing force to the rod-shaped body and is attached to the rod-shaped body via the stopper.

(Embodiments) Hereinafter, the mounting bracket of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings.

1 to 4, a mounting bracket according to an embodiment of the present invention hangs a ballast box 5 of a lighting device 1 with bolts 8.
Shown applied for installation in.

That is, in this embodiment, the mounting bracket 10 has one end fixed to the ballast box 5 and the other end fixed to the ballast box 5.
It includes a springy plate-like member 11 extending outwardly. This plate-like member 11 is provided with a long hole 12 formed along the longitudinal direction at the center in the width direction. In the ballast box 5 in which the ballast 9 for the lighting equipment 1 is installed and housed, mounting brackets 10 are attached to both upper and lower ends of the ballast box 5, as shown in FIG. It is expanding in the direction of

When this ballast box 5 is to be attached to a hanging bolt 8 for ceiling installation, for example, each mounting bracket 10 is strongly curved as shown by imaginary lines in FIG.

Then, a cut groove is formed by the elongated hole 12 on the curved surface of the plate member 11, and the mounting bracket 10 is installed in the middle of the lowest bolt 8 so as to fit the hanging bolt 8 into the groove. do. The bottom of the cut groove appearing in the curved mounting bracket 10 is connected to both end edges of the elongated hole 12, and these end edges are engaged with the grooves of the hanging bolt 8. In this state, when the compressive force applied to the plate member 11 of the mounting bracket 10 to curve it is released, the plate member 11 returns to its original state and its opening angle increases from its arcuate state. Elastic force acts in the direction. However, this elastic force becomes a locking force between both ends of the elongated hole and the thread groove of the hanging bolt 8, and the hanging bolt 8
, and increases the holding force of the mounting bracket 10 to the hanging bolt 8.

In the above-mentioned embodiment, the long hole 12 was provided at 11 degrees of the plate-like member, but as shown in FIG.
One side of 2 may be cut out and opened within a shorter range than its entire length. According to the mounting bracket 20 having such a configuration,
When attached to the hanging bolt 8 as in the first embodiment,
As shown in FIG. 6, the elongated hole side portions 21a and 21b that define the entire notch are free ends, and the other continuous integral side portion 22 is also in the opening angle direction of the mounting bracket. As a result, both ends of the elongated hole that is engaged with the thread groove of the hanging bolt are twisted, and a stronger engagement force is exerted.

Furthermore, the plate-like member of this mounting bracket may be formed into a somewhat arcuate shape in its initial state, that is, before it is attached to the suspension bolt. Furthermore, in the above embodiment,
The case where the mounting bracket is attached to the hanging bolt has been described, but in this case, since the thread of the hanging bolt acts as a stopper, it can be attached at any position along its length. However, even if it is not a bolt like this,
It can be attached to a simple rod-shaped body as long as it is attached as a stopper by installing two bin members formed at mutually adjusted intervals so as to sufficiently prevent the curved mounting bracket from returning. Furthermore, the supported object is not limited to a stabilizer box, and can be applied to any mounted object to be attached to a rod-shaped body.

(Effects of the Invention) As explained above, according to the mounting bracket of the present invention, one end of the rod-shaped body is fixed to the object to be attached, and the rod-shaped body can be attached very easily using the spring-like plate-shaped member having the elongated hole formed in the longitudinal direction. It can be attached at any time with one touch.
