Abstract

PURPOSE:To enable the fixing of a pipe easily and quickly even by a small force by reversing the direction of a screw for adjusting length comprising a nut and a female screw provided at both end parts of a pair of pipes fitted into each other at the center. CONSTITUTION:The body of an expansion rod is made up of a first pipe 10, a second pipe 20, a pipe stopping coupling 30 and a rod hoisting device 40 and press devices 12 and 22 are provided at both ends thereof. The press devices 12 and 22 are provided with contact plates 122 and 222 and screw rods 121 and 221 erected thereon. Nuts 11 and 21 having tread holes 110 and 210 screwed on the screw rods 121 and 221 are fitted into both end parts of the pipes 10 and 20. The nuts 11 and 21 and threads of the screw rods 121 and 221 screwed thereinto are formed in direction opposite to each other. The body is set slightly shorter than the dimensions between the ceiling and a floor or between opposed wall surfaces and fastened temporarily at a desired position. Then, the body is turned to be anchored at a desired position. By this constitution, the pipe is fixed at a desired position easily and quickly by a small force.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic rod which can be supported mainly between a ceiling surface and a floor surface or an opposing wall surface.

[0002]

2. Description of the Related Art In the conventional expansion rod, a first pipe and a second pipe fitted to the first pipe can be fixed to each other so that the first pipe and the second pipe stand upright between a ceiling surface and a floor surface. , The clothes, plant pots, shelves, etc. were horizontally bridged between the opposing wall surfaces, but the first pipe and the second pipe fitted to the first pipe were mounted on the ceiling surface and the floor surface. After fixing both according to the distance to or the distance between the opposing wall surfaces,
It is necessary to finely adjust the tip end of the first pipe or the rear end of the second pipe by slightly protruding so that the ceiling surface and the floor surface, or the wall surface is strongly pressed. A spring-loaded pusher or a screw-movable pusher had to be attached to the front end of the first pipe or the rear end of the second pipe. However, the pusher with a built-in spring is expensive and requires a force to resist the spring force, which is unsuitable for old men and women. Was inappropriate for.

In the telescopic rod which is provided with a second pipe 20 fitted to the first pipe 10 and the second pipe 20, the tip end portion 101 of the first pipe 10 can be fixed.
The first nut 11 is attached to the second nut 21, and the second nut 21 having the screw hole 110 of the first nut 11 and the screw hole 210 screwed into the reverse screw is attached to the rear end portion 201 of the second pipe 20,
The second pipe 20 fixed to the first pipe 10 is rotated to be screwed into the first nut 11 so as to come into contact with the facing surface, and the second nut 2
The second pusher 22 which is screwed into 1 and can be brought into contact with the facing surface can be projected or retracted together.

In the present invention, the first pusher 12 or the second pusher 12
The pushing tool 22 is fixed to one end of the male screw rod 121 or 221 and the male screw rod 121 or 221, which is screwed into the first nut 11 or the second nut 21, and is attached to a facing surface such as a ceiling surface, a floor surface, or a wall surface. Contact object 1 such as a plate or elastic body that can contact
22 or 222.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention is shown in FIGS.

The telescopic rod of this example comprises a first pipe 10, a second pipe 20, a pipe fastening joint 30, and a rod suspending tool 40.

The first pipe 10 is equipped with a first nut 11 and a first pusher 12 which is screwed into the distal end 101 of the first pipe 10.

The first pusher 12 is a disc-like member which is screwed into the first nut 11 and one end of which is fixed to the screw rod 121 and which can be brought into contact with a ceiling surface, a floor surface or a wall surface. Of the abutment 122.

The second pipe 20 has the first pipe 10 fitted therein, and has a second nut 21 at the rear end 201 and a second pusher 22 screwed into the second nut 21.

The second nut 21 is provided with a screw hole 210 formed by screwing a reverse screw into the screw hole 110 of the first nut 11.

The second pusher 22 is a disc-shaped member that can be screwed into the second nut 21 and one end of the screw rod 221 is fixed, and can be brought into contact with a ceiling surface, a floor surface, or a wall surface. Of the abutment 222.

Further, the second pipe 20 has a pipe fastening joint 30 attached to its tip portion 202.

The pipe fastening joint 30 has a large diameter portion 301 and a small diameter portion 302, the large diameter portion 301 is fitted with the tip end portion 202 of the second pipe 20, and the small diameter portion 302 is attached to the first pipe 10.
It is formed such that the pipe 10 can be movably fitted therein and that the pipe 10 can be fixedly attached to the pipe 20 at an arbitrary fitting position by a knob screw 31.

The rod suspending tool 40 has a cylindrical portion 41 that is movably fitted on the first pipe 10 or the second pipe 20, a knob screw 42 that is screwed into the cylindrical portion 41, and a rod that is attached to the cylindrical portion 41. The hook-shaped portion 43 is adapted to be hung, and is formed so that it can be fixed to an arbitrary position of the pipe 10 or the pipe 20 by a screw 42 with a knob.

Another embodiment of the sling device is shown in FIG. The rod hanging tool 40B is a round bar 41B in which the front half 401B is bent in a U shape so that the rod 50 can be placed, the rear half 402B is linearly formed, and the tip 403B is screwed.
And a butterfly nut 42 screwed to the tip 403B of the round bar 41B.
It consists of B and. In order to fix the rod suspending tool 40B to the first pipe 10 or the second pipe 20, a round bar is provided in an appropriate pair of through holes 1 and 2 which are penetrated at arbitrary positions of the first pipe 10 or the second pipe 20. 41B is inserted, the tip 403B
The butterfly nut 42B is screwed onto the
It is fixedly attached to the first pipe 10 or the second pipe 20.

[0017]

Therefore, as shown in FIG. 3, an example of suspending the rod 50 in the room will be described as an example.
After the second pipe 20 is fitted to each of them, and the rod suspending tool 40 is fixed to the arbitrary position of the first pipe 10 by the screw 42 with the knob, the first pushing tool 12 attached to the first pipe tip portion 101 is attached. So that the surface of the contact object 122 of the above-mentioned abuts on the ceiling surface 60, is pulled out from the upright second pipe 20, and by the knob screw 32 of the pipe fastening joint 30 attached to the tip portion 202 of the second pipe 20. The pipe 10 is fixed to the pipe 20.

Next, the pipe 2 integrated with the pipe 10
When each of 0 is rotated, the first pusher 12 abutting on the ceiling surface 60 slightly projects toward the ceiling face 60, and at the same time the second pusher 22 abutting the floor surface 70 slightly moves on the floor surface. Since it projects toward 70, the pipe 20 integrated with the pipe 10 can be surely erected upright between the ceiling surface 60 and the floor surface 70, and the rod 50 can be placed between the pair of rod suspenders 40. Can be hung stably.

[0019]

According to the present invention, between the ceiling surface and the floor surface,
Alternatively, the second pipe fixed to the first pipe between the opposing wall surfaces.
The pipe can be supported quickly, easily and reliably,
In addition, the structure is simple and it can be manufactured at low cost.
