  Many of the contact members attached to both ends of a conventional stretchable telescopic rod have a flat contact surface assuming that they are attached to the wall surface. When the contact surface of the contact member has a planar shape, the area of the portion where the contact surface of the contact member and the surface of the columnar column are in contact with each other when the pipe rack is mounted between the columnar columns is as follows. Although it is narrow and can withstand a certain amount of force from the vertical direction to the stretchable telescopic rod, there is a problem that it easily disengages when a lateral force is applied. For this reason, there has been proposed a structure in which the shape of the abutting surface of the abutting member of the telescopic strut rod is a curved surface conforming to the shape of the side surface of the columnar column like a columnar column of a pipe rack.

  However, it is troublesome to separately prepare a stretchable telescopic rod to be used depending on whether the contacted surface to which the stretchable telescopic rod is to be attached is a flat surface such as a wall or a cylindrical shape such as a pipe rack column. .

  In view of this, the present invention is not limited to using a stretchable telescopic rod depending on whether the abutted surface to which the stretchable telescopic rod is to be attached is a flat surface such as a wall or a cylindrical shape such as a pillar of a pipe rack. An object is to provide a stretchable telescopic rod that can be used even on a contact surface.

  In addition, the present invention can be fixed securely even if the contacted surface to which the stretchable telescopic rod is to be attached is a flat surface such as a wall or a cylindrical shape such as a pipe rack column. An object of the present invention is to provide a stretchable telescopic rod that does not easily fall off even when a load is applied.

  In order to solve the above-mentioned problem, the present invention according to claim 1 is formed such that an inner pole arranged in a telescopic manner inside the outer pole is extended and retracted from the outer pole and attached to both ends. In a stretchable telescopic rod that is arranged and fixed at a predetermined location by bringing the contact surface of the contact member into contact with the contacted surface by an urging force, the contact member has a cylindrical contacted surface. A curved surface portion suitable for contacting the contact surface and a flat surface portion suitable for contacting the planar contacted surface are provided.

  In order to solve the above-mentioned problem, the present invention described in claim 2 is the stretchable telescopic rod according to claim 1, wherein the curved surface portion has a radius of curvature when the contacted surface is cylindrical. It is 9.5 to 12.5 mm.

  In order to solve the above-mentioned problem, the present invention according to claim 3 is the stretch telescopic rod according to claim 1 or 2, wherein the abutment attached to one side or both sides of the outer pole or the inner pole. The member is attached to be rotatable about the longitudinal direction of the outer pole and the inner pole as a rotation axis.

  According to the stretchable telescopic rod according to the present invention, the curved surface part suitable for contacting the cylindrical contacted surface on the contact surface of the contact member attached to both ends of the stretchable elastic rod, Since a plane portion suitable for abutting against the abutted surface is provided, is the abutted surface to which the extension telescopic rod is attached a flat surface such as a wall or a cylindrical shape such as a pipe rack column? Thus, there is an effect that any of the contacted surfaces can be used without properly using the stretching telescopic rod.

  In addition, according to the stretchable telescopic rod according to the present invention, even if the contacted surface to which the stretchable telescopic rod is to be attached is a flat surface such as a wall or a cylindrical shape such as a pillar of a pipe rack, it is securely fixed. This has the effect of not falling off easily even when a load is applied from any direction.

  Hereinafter, a stretchable telescopic rod according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a preferred embodiment of a stretchable telescopic rod according to the present invention, and FIG. 2 is a perspective view of a contact member attached to an end of the stretchable telescopic rod.

[Structure of tension telescopic rod]
A stretchable telescopic rod 1 shown in FIG. 1 includes an inner pole 5 disposed in a nested manner inside an outer pole 3, and is formed to be telescopic by moving the inner pole 5 in and out of the outer pole 3. . And the contact members 10 and 10 are attached to the both ends of the stretchable telescopic rod 1, respectively.

  The outer pole 3 is formed in a hollow interior, and a spring member (not shown) is accommodated. Further, the inner pole 3 is also formed with a hollow inside. The inner pole 3 is inserted in a state where a spring member (not shown) disposed in the outer pole 5 is accommodated therein. A convex portion (not shown) is provided on the inner surface of the inner pole 3 in the vicinity of the end portion of the inner pole 3 that is inserted into the outer pole 5. When the relative rotation is performed, the convex portion moves along the spiral spring member, so that the inner pole 3 moves into and out of the outer pole 5, and the total length of the stretchable telescopic rod 1 is adjusted to an appropriate length. You can do that. The structure for adjusting the length of the stretchable telescopic rod 1 is not limited to this, and an appropriate structure can be adopted.

[Configuration of contact member]
As shown in FIG. 2, the contact member 10 includes an attachment portion 11 for attaching to the open end of the inner pole 3 or the outer pole 5, and a main body portion 13 formed so as to expand from the attachment portion 11. I have. The contact member 10 is made of elastic synthetic resin, synthetic or natural rubber. Then, the contact surface of the main body 13, that is, the wall surface (hereinafter referred to as “planar contacted surface”) W to which the stretchable telescopic rod 1 is to be attached, or the columnar column of the pipe rack (hereinafter referred to as “ A cylindrical contacted surface is referred to as.) A curved surface portion 15 that comes into contact with the surface of the cylindrical contacted surface P in close contact with the surface of the cylindrical contacted surface P on the surface that contacts P. Flat portions 17, 17 that come into contact with the contact surface W are formed on both sides of the curved surface portion 15. The contact member 10 attached to the inner pole 3 and the outer pole 5 is attached so that the inner pole 3 side or the outer pole 5 side or both sides thereof can rotate with respect to the open ends of the inner pole 3 and the outer pole 5. Thus, even when the inner pole 3 is appropriately rotated, the alignment can be performed so as to be in close contact with the cylindrical contact surface P.

  The curved surface portion 15 is formed in a shape that matches the curvature of the cylindrical abutting surface P when the portion to which the stretchable telescopic rod 1 is attached is the cylindrical abutting surface P. Therefore, the curvature of the curved surface portion 15 can be appropriately set according to the curvature of the cylindrical contacted surface P. For example, since a columnar column of a pipe rack assembled by appropriately combining metal components has a diameter of 19 to 25 mm in general, the curvature radius of the curved surface portion 15 is set to 9.5 to 12.5 mm. Thus, it is possible to securely attach the curved surface portion 15 in close contact with the columnar column of the pipe rack.

  Further, on both sides of the curved surface portion 15, plane portions 17 and 17 having a substantially “D” shape are formed. The flat portions 17, 17 are formed so as to be in close contact with a predetermined area when the contact surface is a flat contacted surface W such as a side surface of a wall or furniture. Accordingly, the abutting member 10 can firmly fix the stretchable telescopic rod 1 regardless of whether the abutting surface is a planar abutting surface W or a cylindrical abutting surface P.

[Operation of the tension telescopic rod]
First, the length is adjusted by moving the inner pole 5 in and out of the outer pole 3 by rotating the inner pole 5 in accordance with the interval between the places where the stretchable telescopic rods 1 are to be attached. In this case, it is slightly longer than the interval between the mounting locations. Then, the contact member 10 of the inner pole 3 or the outer pole 5 is brought into close contact with a predetermined portion of the planar contact surface W or the cylindrical contact surface P which is a contact surface. Next, the elastic member 1 is compressed so as to be shorter than the mounting interval by pressing the contact member 10 on the opposite side, and the planar contact surface W or the cylindrical contact surface on the opposite side is compressed. It fixes in the attachment place by making it closely_contact | adhere to P or rotating the inner side pole 5 to an expansion | extension direction. At this time, when the contact surface is a columnar contacted surface P, the curved surface portion 15 can be brought into close contact with the curved surface by rotating the contact member 10.

  As described above, the preferred embodiment of the stretchable telescopic rod according to the present invention has been described. However, the present invention is not limited to the above-described embodiment, and is within the scope not departing from or changing the technical idea of the present invention. Various modifications are possible.
