Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an article having a columnar portion,
For example, the present invention relates to a simple structural support device that can quickly and safely mount and remove a lighting fixture, a TV camera, a flag raising pole, and the like having civil engineering, building pipe supports, columns, and the like.

[0002]

2. Description of the Related Art In general, articles having a columnar portion are fixed to a firm base or a supporting member.
When the base and the support member are large, a structure is adopted in which the columnar portion is tightened to the base and the support member with bolts and nuts.

On the other hand, a pipe support for civil engineering and construction, which is prized at a temporary construction site, cannot be self-supported by itself because it has a small base attached. Since it is necessary to hold the pipe support and perform the pipe length expansion / contraction adjustment work with the other hand, the work of properly installing the pipe support at a predetermined position requires labor and labor.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a support device having a simple structure capable of quickly and safely attaching and detaching an article having the columnar portion.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the first invention is to provide a main body having a receiving portion having a concave portion that engages with one side of a pillar-shaped portion of an article. Installed in
Behind the receiving part, a lock slider guide is provided obliquely so that the lower part is away from the receiving part, and a lock slider provided at the end with a hook for engaging the pillar-shaped part of the article with the lock slider guide. It is an apparatus for supporting an article having a column-shaped portion, which is provided so as to be vertically movable and rotatable.

According to a second aspect of the present invention, there is provided a support device according to the first aspect of the present invention, wherein a support ring of a columnar portion comprising an arcuate guide tube and an arcuate slide stop bar is provided above the receiving portion. According to the invention of 1 or 2, in the first or second invention, the main body comprises a fixed leg and a movable leg.

[0007]

According to a first aspect of the present invention, a lock-slider which has been opened is closed and dropped after the column-shaped portion of the article is brought into contact with the receiving portion. The slider is moved rearward by the lock slider guide, and the columnar portion is tightened to the receiving portion, and when receiving the vibration, it is tightened more and more.

According to a second aspect of the present invention, the snap ring temporarily fixes the pillar-shaped portion, thereby facilitating the opening / closing operation of the lock slider. Also the third
The present invention is a device which is convenient for moving and storing when it is necessary only at the time of erection, such as a pipe support, or in the case of a support device which is used for a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a support device for mounting a pipe support for civil engineering and construction will be described below with reference to the drawings.

In the drawing, reference numeral 1 denotes a fixed leg on which a receiving plate 2 is fixed on an upper portion, and 3 and 3 denote movable legs provided rotatably on the fixed leg.
The wing nuts 4, 4 can be used to fix the opening angle to any desired angle, and when not in use, can be folded at the imaginary line.

Reference numeral 5 denotes a vertical post (receiving portion) having a concave portion 5a fixed to the fixed leg 1. In the embodiment, an angle is used, but a channel or an H-shaped member may be used. Reference numeral 6 denotes a lock slider guide provided on the fixed leg 1 at an angle so that the lower part is away from the vertical post 5 and a lock slider 8 provided with a hook portion 7 at the tip is vertically movable and rotatable. Has been.

Reference numeral 9 is a retaining ring composed of an arc-shaped guide tube 9a mounted on the receiving plate 2 and an arc-shaped slide retaining rod 9b, and a stopper knob 10 is provided at the tail portion of the slide retaining rod 9b. As shown in FIG.
Thereby, it fits into the hole 2a provided in the receiving board 2. Then, when the stopper knob 10 is pulled up, the slide stop rod 9b moves to the spring 1 provided in the guide rod 9a.
2, it jumps out of the guide tube 9 a and embraces and temporarily fixes the lumbar tube P of the pipe support as shown in the imaginary line.

Reference numeral 13 is a storage base for the lock slider 8 provided on the upper portion of the fixed portion 1, and 14 is a clip for the lock slider 8.

Next, the method of use will be described. When not in use, the movable legs 3 and 3 are closed as shown by imaginary lines, and the lock slider 8 is opened and raised, and the storage base 13 is opened.
Hang it on and stop with clip 14.

In use, the movable legs 3 and 3 are appropriately opened to be self-supporting at a predetermined position. First, the lumbar tube P of the pipe support is put on the vertical post 5 and then the slide stop rod 9b which is opened is used as a stopper knob. 10 is pulled up against the spring 11 to remove it from the hole 2a, and the spring 12 closes it.
The waist tube P is held and temporarily fixed.

Next, when the lock slider 8 is removed from the clip 14 and the storage base 13 and rotated in the direction of the waist tube P and dropped,
As the hook portion 7 holds the waist tube P and falls, the lock slider 8 moves the hook portion 7 in the direction of the vertical post 5 by the lock slider guide 6, and tightens the waist tube P between the hook portion 7 and the vertical post 5.

When removing the waist tube P, the reverse operation may be performed.

[0018]

Different Embodiment If the article is relatively light, the snap ring 9 can be omitted. Further, the retaining ring 9 can be provided at the lower part, but it is better not to provide it for convenience. Although the main body is a tripod in the embodiment, it may be a bracket provided on a building or a vehicle.

[0019]

According to the present invention, it is possible to easily and quickly and safely and reliably make a column-shaped portion of an article self-supporting, and particularly as a support device for erection of a pipe support for civil engineering and construction. It is suitable.
