Description

[Detailed description of the invention] This invention relates to suspension support fittings, and
It is used to suspend and support lighting equipment and wiring parts from shape steel, channel steel, and other construction materials, and the screw-fastened parts do not loosen even when subjected to external shocks or vibrations, and are shock and vibration resistant. The present invention relates to a suspension support fitting which is excellent in that the various members mentioned above can be stably mounted and supported by preventing the fitting itself from falling off, and furthermore, the support angle can be freely adjusted.

Conventionally, when suspending and supporting lighting equipment, wiring parts, etc. from the construction materials of building structures, for example,
Publication No. 3, Utility Model Publication No. 8120, Utility Model Publication No. 48-8120, Utility Model Publication No. 49-
As in Publication i5430, etc., a metal fitting main body is formed into a U-shape when viewed from the side so as to sandwich construction materials, and a fixing screw is provided in the metal fitting main body so as to be able to move forward and backward to press the tip against the surface of the construction material;
A suspension support fitting has been used which includes a suspension support body connected to a metal fitting body and supporting a hanging rod member.

In this case, since the main body of the fitting is screwed to the construction material, it may loosen due to external shocks and vibrations, resulting in lack of support stability such as the fitting itself falling off.
In addition to being dangerous, since the hanging rod members are arranged vertically, it may be difficult to use depending on the conditions at the installation site.

Therefore, this idea consists of a side U-shaped metal fitting body in which a clamping opening is formed to hold a specified construction material between the upper and lower plates facing each other, and the tip is pressed against the construction material surface that is clamped in the clamping opening. In the suspension support bracket, the suspension support is composed of a fixing screw provided on the upper plate so as to be able to move forward and backward as much as possible, and a suspension support body having a substantially U-shaped cross section, on which a hanging rod member is suspended and supported and connected to the lower plate. A shock absorbing member is interposed between the plate and the nut member to which the set screw is screwed, and apart from this, a swing adjustment elongated hole is provided at the bottom of the suspension support body, which is continuously opened at the bottom and the left and right sides. The suspension rod member penetrated through the suspension support body is screwed to a nut member located inside the suspension support body, and a shock absorbing member having a U-shaped bottom surface is interposed between the nut member and the bottom part, and the suspension rod member is inserted from the suspension support body. The above-mentioned drawbacks are solved by supporting the device, and one embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 shown in the figure is a metal fitting main body having a generally U-shaped side surface, and a predetermined construction material S,
For example, a clamping opening 4 for clamping L-shaped steel, channel steel, etc. is formed.

Specifically, it is made by bending a rectangular plate material with an appropriate thickness, and then bending the bent parts on both sides of the center part again so that the ends of the bent parts abut against each other to form a roughly rectangular cylindrical cross section. At the same time, the press-stop pieces 5 extending from the lower plate 3 to both sides by symmetrical notches formed from the side edges of both sides are integrally bent and formed.

Each of the upper and lower plates 2 and 3 has a substantially groove-shaped cross section, which prevents the metal fitting body 1 itself from becoming distorted due to the clamping action of the fixing screw 6, which will be described later. Part 2
This is to facilitate the connection of a suspension support 25, which will be described later, on which the suspension support 7 is suspended.

In addition, the pressing piece 5 is abutted against the construction material S surface, and the construction material S
The fixing stability is improved by increasing the contact area against the

Of course, the shape and structure of the metal fitting main body 1 can be adopted as various types as long as there is no change in the basic form. This includes changing the opening angle.

Reference numeral 6 denotes a fixing screw, which is provided on the upper plate 2 so as to be able to move forward and backward so that its tip is pressed against the surface of the construction material S inserted into the clamping opening 4 of the metal fitting main body 1.

This fixing screw 6 has a slightly depressed center at its tip and an annular raised edge 7 on its outer periphery.The fixing screw 6 is hardened by quenching and heat treatment to withstand pressure tightening. It is inserted from the outside into the insertion hole 2A drilled in the opening 4.
It is supported in a pressed state on the back surface of the upper plate 2 by shock absorbing members 20A and 20B interposed between it and a nut member 8 disposed therein.

These shock absorbing members 20A and 20B may be of any type as long as they themselves have a buffering function; for example, as shown in FIGS. 1 to 4, the shock absorbing members 20A may be made of rubber or an elastic material similar to rubber. Alternatively, as shown in FIG. 5, it may be a coil spring shock absorbing member 20B having an elastic action that resists compressive force, and its material and structure can be selected as appropriate.

In the case of the former 20A, as shown in FIGS. 1 to 3, it is formed to a size that fits inside the upper plate 2, which is bent into a substantially groove-shaped cross section, and is bored into the 20A itself. A set screw 6 passing through a through hole 21 is screwed into a substantially rectangular nut member 8, and although the shock absorbing member 20A and the nut member 8 are separated in the figure, these 20A.

8 may be appropriately bonded and integrated.

Alternatively, as shown in FIG. 4, a thin plate 22 is adhesively fixed under a similarly formed shock absorbing member 20A.

A set screw 6 passing through 22 may be screwed into the hexagonal nut member 8.

In the case of the latter 20B, it is compressed and arranged between a regulating plate 23 that contacts the back surface of the upper plate 2 and a restraining plate 24 arranged on the hexagonal nut member 8.

Of course, the shock absorbing members 20A and 20B are attached to the set screws 6.
It must have the strength to withstand the tightening force when fixed to the specified construction material S, and have sufficient expansion and contraction action to exert a buffering function when fixed, It is clear that if this is satisfied, the intervening means and structure are not limited to the illustrated example.

The lower plate 3 of the metal fitting main body 1 is provided with a substantially U-shaped cross section so as to be swingable in the front and back direction of the lower plate 3 via connecting screws 26 that pass through connecting holes 29 drilled in the left and right parts of the lower plate 3. A suspension support 25 is connected thereto.

At the bottom of the suspension support 25, a suspension rod member 27, such as a suspension bolt, which passes through a swing adjustment long hole 30 that is continuously opened at the bottom and left and right sides, is connected to a nut member located inside the suspension support 25. 31 and has a U-shaped bottom surface 32 between the nut member 31 and the bottom.
8, the suspension support 25 is made swingable in the left and right direction.
Support from

This shock absorbing member 28 includes the shock absorbing members 20A, 2
It is formed separately from the 0B, and its material is, for example, rubber or an elastic material similar to rubber, and its U-shaped bottom surface 32 is in contact with the bottom inner surface of the suspension support 25 in an L-shape to absorb shock. The member 28 and the nut member 31 are constructed integrally or separately so that they can be combined during use.

Next, to explain how to use this, the metal fittings can be attached by inserting this S into the appropriate position of the predetermined construction material S that is to be used to suspend and support various components such as lighting equipment and wiring parts. Set the main body 1 and screw in the set screw 6 to attach the shock absorbing member 20A.
, 20B is fixed by pressing its tip against the construction material S surface against the compression and restoring action of itself.

After that, various members are suspended and supported by the suspension support 25, suspension rod member 27, and shock absorbing member 28.
(See Figures 2, 3, and 5).

Therefore, the nut member 8 into which the fixing screw 6 is screwed when fixing the metal fitting main body 1 to the construction material S is the shock absorbing member 20A interposed between the nut member 8 and the upper plate 2;
20B is strongly pressed against the upper plate 2, and the suspension rod member 27 is engaged and supported by the suspension support 25 connected to the metal fitting body 1 by the shock absorbing member 28 and the nut member 31. Due to external shocks and vibrations, this is caused by the construction material S, various members L, and hanging rod members 2.
7. No matter whether it is from the metal fitting body 1 via the suspension support 25, it is not transmitted to the screwed part between the nut member 8 and the fixing screw 6, and furthermore, between the suspension rod member 27 and the nut member 31. Since there is no possibility of loosening, the metal fitting main body 1 itself is fixed with screws in a stable state without any of the various members falling off, and has extremely high suspension support stability.

That is, the screwing position of the set screw 6 for fixing to the construction material S is determined by the shock absorbing members 20A and 20B, and
Nut member 3 of the hanging rod member 27 that suspends and supports various members
The part where the screw is fastened to 1 is used to indirectly use and support the shock and vibration by the shock absorbing member 28, which buffers the impact and at the same time absorbs it, so there is no loosening of the part where the screw is fastened. , fixation, and support stability.

In addition, the shock absorbing members 20A and 20B can be easily incorporated into a conventionally provided mounting bracket consisting of a combination of a metal fitting body and a fixing screw, and the basic shapes of the metal fitting body 1 and the fixing screw 6, This can be done without changing the structure, and the screw-fastening operation is exactly the same as the conventional one, making it easy to handle, and the structure is simple and can be provided at low cost.

Furthermore, the suspension rod member 27 that is engaged and supported by the suspension support 25 is inserted into the swing adjustment elongated hole 30 that is continuously opened at the bottom and left and right sides of the suspension support 25, and is fitted with a nut. Part 3
1, the shock absorbing member 28 having a U-shaped bottom surface 32 is interposed between the nut member 31 and the bottom, and a free angle can be created along the swing adjustment elongated hole 30. It can be tilted and oscillated, and even if it cannot be supported vertically due to various circumstances at the installation site, it can be supported tilted, and the shock absorption effect is not diminished in the slightest. .

As explained above, according to this invention, when lighting equipment, wiring parts, etc. are suspended and supported from L-beam steel, channel steel, and other construction materials in building structures, external shocks and vibrations There is no loosening of the screw-fastened parts, which has excellent shock and vibration resistance, and the metal fittings themselves are prevented from falling off, making it possible to stably support the various components mentioned above. It can be tilted and supported at a suitable angle, has a simple structure, and can be provided at low cost, which is extremely useful in practice.
