Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic pole which can be used for a hanging device and has a length adjustable.

[0002]

2. Description of the Related Art Conventionally, as in the case of Japanese Utility Model Laid-Open No. 54-14727, one in which one protrusion is attached to an inner pole and is biased by a spring and a plurality of receiving holes is provided in the outer pole is proposed. Has been done.

[0003]

In the above-mentioned conventional example, since the outer pole is provided with a plurality of receiving holes, the appearance becomes unaesthetic and the inner pole can slide on the outer pole. Since the inner pole is inserted, the outer diameter of the inner pole is made smaller than the inner diameter of the outer pole, and there is a problem that rattling occurs between the both.

[0004]

According to the present invention, there is provided a telescopic pole having a length adjustable by inserting an inner pole slidably into a pipe-shaped outer pole.
The inner pole is provided with mounting holes at a plurality of positions so that the spring-biased protrusions are attached to the mounting holes so that they can be retracted and retracted, and the outer pole is fitted with the protrusions at one position. The mounting hole penetrates in the direction orthogonal to the longitudinal direction, the tip has a small-diameter receiving portion, and the protrusion has a substantially cylindrical shape and the rear portion has a large-diameter retaining portion. At the same time, an insertion hole is provided from the rear end to insert a part of the spring, and the protrusion with the spring inserted is inserted from the rear end of the mounting hole to bring the retaining portion into contact with the receiving portion. Insert the inserted stem into the rear end of the mounting hole.
The protrusion is attached to the inner pole in a state of partially protruding from the tip of the attachment hole, and one of the plurality of protrusions is fitted into the receiving hole to adjust the length.

[0005]

The overall length can be adjusted by changing the protrusion of the inner pole fitted into the receiving hole of the outer pole. Further, when any one of the protrusions is fitted into the receiving hole, the other protrusion presses the inner surface of the outer pole by the force of the spring urging the protrusion.

EXAMPLE A telescopic pole 1 has a rod-shaped inner pole 3 slidably inserted into a circular pipe-shaped outer pole 2, and a bendable portion of a coil spring is provided at an end of the outer pole 2. 5
A substantially spherical engaging portion 6 is attached through the inside, and a ring-shaped hooking portion 4 is attached to an end of the inner pole 3 to be used as a hanging tool.

The inner pole 3 has a guide groove 1 over the entire length.
1 is provided, the outer pole 2 is provided with a protrusion 12 projecting inward at the end, and the protrusion 12 engages with the guide groove 11 and slides only straightly. You can't.

At a portion of the inner pole 3 to be inserted into the outer pole 2, three mounting holes 8 ... 8 are provided at predetermined intervals, and the projecting members 9 ... Mounting holes 8, the tip portion is circular slightly smaller diameter catch
Part 8a is formed, projections 9 protrude the tip is hemispherical in cylindrical, rear end retaining剖9a is that somewhat larger diameter
It is formed, and the insertion hole 9b is provided from the rear end portion therein. Then, the projection 9 is inserted from the rear end of the mounting hole 8, the trapezoidal spring 10 is inserted into the insertion hole 9b of the projection 9, and the rear end of the mounting hole 8 is caulked and stopped. Projections 9, which is biased in a protruding direction by a spring 10, the receiving portion 8a of the retaining portion 9a mounting hole 8
It is prevented from coming off in a state in which the tip portion is brought into contact with and is projected. Further, the outer pole 2 is provided with a receiving hole 7 at one location.

The inner pole 3 is set on the outer pole 2 and the guide groove 1 is formed.
9 and 9 of the inner pole 3 and the receiving holes 7 of the outer poles 2 are aligned in a straight line, and the frontmost protrusion 9 is located at the receiving hole 7 position. At this time, the force of the spring 10 causes the protrusion 9 to protrude and fit into the receiving hole 7. In order to adjust the length, the protrusion 9 protruding from the receiving hole 7 may be pushed in, the inner pole 3 may be slid, and the other protrusion 9 may be fitted into the receiving hole 7.

This telescopic pole 1 has an engaging portion 6 at the tip,
It is used by inserting it into the support 13 attached to the ceiling from below and rotating and supporting it, and hanging clothes or the like on the hook 4.

[0011]

As described above, according to the present invention, the entire length can be adjusted by providing only one receiving hole in the outer pole, so that it does not look unsightly and fits into the receiving hole. Since the protrusion that is not inserted presses the inner surface of the outer pole, there is an effect that rattling of the outer pole and the inner pole can be reduced.

In addition, the protrusion can be inserted from the rear end of the mounting hole penetrating the inner pole so that the retaining portion abuts the receiving portion and the rear end portion of the mounting hole is prevented from coming off. Therefore, there is an effect that the mounting work is easy no matter where the mounting hole is on the inner pole.
