DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe stand using a hollow pipe as a leg and a non-slip pipe stand therefor.

[0002]

2. Description of the Related Art A hollow pipe is widely used as a leg of a desk or chair, a leg of a stand on which a television or the like is mounted, and the like. Since the pipe stand using a hollow pipe is lightweight and can support a large load, it can be used as a leg for desks, chairs, tables on which objects are placed, electronic equipment, etc. Has been used as.

When a pipe stand is used as a leg of a chair or a table, a hollow rubber or the like is inserted into a pipe to be used as a rubber foot in order to prevent slippage and absorb impact.

[0004]

As described above, when hollow rubber or the like is used as the rubber foot of the pipe stand, it is necessary to insert the rubber foot into the pipe before bending the pipe. At this time, after assembling the pipe stand, it is necessary to adjust the mounting position of the rubber foot so that the rubber foot comes to an appropriate position in contact with the floor. Since this adjustment work needs to be performed before assembling the pipe stand, it has been difficult to perform the adjustment work for accurately determining the mounting position.

It is an object of the present invention to provide a pipe stand in which the work of attaching an elastic member during assembly is simplified. Another object of the present invention is to provide a non-slip pipe stand that can be easily attached after bending a pipe.

[0006]

According to a first aspect of the present invention, in a pipe stand using a hollow pipe as a leg, the elastic member and the pipe are engaged with each other while a band-shaped elastic member is wound around the pipe. The elastic member is fixed to a predetermined position of the pipe by an engaging portion provided to be engaged.

The pipe stand comprises, for example, a band-shaped elastic member having a projection at one end and a hole at the other end, and a hollow pipe having a hole at a predetermined position. The elastic member is wound around the pipe, and the protrusion of the elastic member is pressed into the hole of the elastic member and the hole of the pipe to fix the elastic member to the pipe.

Further, projections are provided at both ends of the elastic member, and when the elastic member is wound around the pipe, the projections at both ends of the elastic member are pressed into the same hole of the pipe to fix the elastic member to the pipe. You may.

Alternatively, two projections are provided on the elastic member,
The pipe is provided with two holes corresponding to the two protrusions of the elastic member. When the elastic member is wound around the pipe, each protrusion of the elastic member is pressed into the corresponding hole of the pipe to fix the elastic member to the pipe. You may.

Further, the outer diameter of a part of the protrusion of the elastic member is made larger than the outer diameter of the root part, and the protrusion and the hole of the elastic member are made of a high-hardness elastic material, and the other parts have a lower hardness. It is also possible to use an elastic material. In this case, since the protrusion is made of a high-hardness elastic material, the protrusion of the elastic member press-fitted into the hole of the pipe hardly comes off even when an external force is applied. The other portions are made of an elastic member having a lower hardness than the other portions, so that a portion in contact with the floor can obtain an appropriate frictional force.

According to the first aspect, the elastic member (for example, rubber foot) is formed by the hole provided at a predetermined position of the pipe.
Since the mounting position of the elastic member is determined, it is not necessary to adjust the mounting position of the elastic member before assembling the pipe stand as in the related art, and the assembling work is simplified. further,
Since the elastic member can be replaced even after assembling the pipe stand, even if the parts are defective or abrasion occurs, only the elastic member can be replaced and the pipe stand can be used as it is.

According to a second aspect of the present invention, in a pipe stand using a hollow pipe as a leg, the elastic member and the pipe are engaged with each other while the hollow cylindrical elastic member is passed through the outside of the pipe. The elastic member is fixed to a predetermined position of the pipe by the provided engaging portion.

The pipe stand comprises, for example, an elastic member having a hollow cylindrical shape provided with a projection on an inner peripheral surface and an elastic member provided with a hole at a predetermined position. The elastic member is fixed to the pipe by inserting the protrusion of the member into the hole of the pipe.

In another form, a hole is provided in a side surface of the elastic member, and the hole of the elastic member and the hole of the pipe are fixed from outside with a stopper. According to the second aspect, the mounting position of the elastic member is determined by the hole provided at the predetermined position of the pipe, so that there is no need to adjust the mounting position of the elastic member, and the assembly work of the pipe stand is simplified. Become.

According to a third aspect of the present invention, a non-slip pipe stand is formed of a band-shaped elastic member that can be wound around the pipe, and the elastic member is configured to be engageable with a predetermined position of the pipe while being wound around the pipe. .

The non-slip for a pipe stand is formed of, for example, a band-shaped elastic member having a projection at one end having a central portion whose outer diameter is larger than the outer diameter of a root portion, and a hole at the other end. . When attaching this non-slip to the pipe,
A hole is provided in a predetermined position of the pipe, a non-slip is wrapped around the pipe, and its protrusion is pressed into a hole at the other end of the non-slip and a hole in the pipe to be fixed to the pipe.

Further, it is also possible to provide protrusions at both ends of the slip stopper and press-fit the two protrusions into the same hole or two holes of the pipe to fix the slip stopper to the pipe.
According to the third aspect of the present invention, the non-slip mounting position is determined by winding the non-slip around the pipe and fixing the non-slip to the pipe by the engaging portion, so that it is not necessary to adjust the non-slip mounting position before assembling the pipe stand. , Installation work is simplified. Further, since the non-slip can be replaced even after the assembly of the pipe stand is completed, the non-slip can be replaced as it is even if the non-slip failure or wear occurs.

According to a fourth aspect of the present invention, there is provided a slip stopper for a pipe stand using a hollow pipe as a leg, comprising a hollow cylindrical elastic member capable of passing through the outside of the pipe, wherein the elastic member is provided outside the pipe. It is configured to be able to engage with a predetermined position of the pipe while passing through.

According to the fourth aspect of the present invention, the position of the non-slip is fixed when the pipe stand is assembled by fixing the position of the non-slip by fixing the non-slip to the pipe by engaging the pipe with the non-slip. , Installation work is simplified.
