Abstract

The present invention relates to a telescopic rod capable of maintaining a tight installation state even when the telescopic rod is intended to be vertically or horizontally inclinable without being intended to be vertically or horizontally inserted. More specifically, the present invention relates to a telescopic rod, And a bent portion is formed at a predetermined interval on a contact surface that abuts against the mounting surface so that a part of the outer periphery of the bent portion can be always tightly adhered to the mounting surface even if the elongated rod is inclined.

Description

Expansible bar}

The present invention relates to a telescopic rod, and more particularly to a telescopic rod capable of maintaining a tightly installed state even when the telescopic rod is not intended to be vertically or horizontally inclined or intended to be inclined.

Generally, the telescopic rod is composed of two or more tubes having different diameters, and the entire length of the telescopic rod can be varied by screwing the inner rod inserted into the outer rod having a large diameter or passing an elastic body such as a compression spring between the outer rod and the inner rod. The telescopic rods can be installed horizontally between walls, window frames or door frames to form curtains, curtains, etc., or to use medallions for children's swings, or vertically between floors and ceilings, And it is widely used without any restriction on the purpose of use and use, and the use thereof is increasing.

An end cap is formed at the end of the conventional stretchable rod to prevent damage to the door frame and the window frame caused by the tubular outer bar or the end of the inner bar being directly pressed against the window frame or the door frame and the ends of the outer bar or the inner bar are slid An end cap made of rubber or synthetic resin is provided to prevent disassembly of the telescopic rod.

The end cap is formed so that the contact surface is wider than the diameter of the outer rod or the inner rod so as to ensure a wide contact surface so that the extensible rod can be firmly installed.

However, when the conventional telescopic rod is installed without being held horizontally or vertically by the load of a shelf or the like, the entire end surface of the end cap can not be closely contacted, and only a part of the end surface is closely adhered, .

Therefore, if the shelf or curtains installed on the telescopic rods are dropped, the stored articles may be damaged. In addition, it is troublesome to install the new telescopic rods again. In addition, when there is a large load or sharp articles, There is a problem.

Therefore, the object of the present invention is to provide a telescopic rod which is provided with a sufficient grounding area even when the telescopic rod is not inclined horizontally or vertically so that the telescopic rod can not be dismantled arbitrarily

The object of the present invention is to provide an end cap comprising an outer rod constituting a stretchable rod or an end cap inserted and fixed to an end of the inner rod and forming a bent portion at a constant interval on a contact face abutting against the mounting face, So that it can be closely adhered to the surface.

According to the present invention, according to the present invention, it is possible to maintain a firmly adhered state even when the telescopic rod is tilted at will, so that the installation of the telescopic rod can be prevented from being released, So that it is possible to mount the telescopic rod at an inclined position, so that it is possible to cope with a place where a tilted telescopic rod is required.

Hereinafter, the most preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the drawings, the same reference numerals are given to the same components as much as possible even if they are shown in different drawings.

FIG. 1 is a perspective view showing the construction of a telescopic rod according to the present invention, FIG. 2 is a perspective view showing the construction of the end cap according to the present invention, and FIG. 3 is a side sectional view showing a deformed state of the end cap according to the installation state of the present invention.

According to the drawing, the telescopic rod of the present invention has a telescopic rod body 10 composed of one or more inner rods 12 and outer rods 14 joined together in a longitudinal direction along a longitudinal direction thereof, And an end cap (20) having an engagement surface (22) for engaging with both end portions of the end cap (20) and having a contact surface (24) The folded portion 26 is formed on the surface 24 at a position spaced apart from the edge by a predetermined distance.

The stretchable rod main body 10 can be elastically stretched by screwing the inner bar 12 and the outer bar 14 into a stretched or contracted state or by interposing an elastic body such as a compression spring between the inner bar 12 and the outer bar 14 .

The end cap 20 can be molded and formed using synthetic resin or rubber. On one side of the end cap 20, an engagement hole 22 is formed so as to be fitted to an end of the inner bar 12 or the outer bar 14, A contact surface 24 for fixing the extensible bar body 10 is formed in close contact with a mounting surface of a wall or door frame on which the body 10 is installed.

The fitting hole 22 may be inserted into and fixed to the outer circumferential surface of the inner rod 12 or the outer circumferential surface of the outer rod 14 or may be inserted and fixed to the inner circumferential surface thereof.

The contact surface 24 may be integrally formed with or separately formed from the coupling hole 22 so that the coupling hole 22 is formed by molding a relatively hard synthetic resin, It is possible to increase the coefficient of friction of the contact surface 24 and to prevent the deformation of the engagement hole 22 due to the force acting on the extensible bar body 10, which is preferable.

At this time, a bent portion 26 is provided at a position spaced a certain distance from the rim of the contact surface 24 toward the center of the stretchable rod body 10. The bent portion 26 may have a semicircular cross- As shown in Fig.

Although the bent portion 26 has a semicircular cross-sectional shape, the bent portion 26 may have a rectangular or triangular cross-sectional shape.

In addition, it is preferable that the bent portion 26 is formed to have a certain distance in a plurality of rows so that it can cope with the inclination degree of the extensible rod body 10 properly.

As shown in Fig. 3a, when the stretchable rod main body 10 is vertically or horizontally held, the entire stretchable bar of the present invention constructed as described above is tightly fixed to the mounting surface entirely. 3B, when the telescopic rod main body 10 is inclined, the contact surface 24 is folded on the basis of the bent portion 26 to be spaced apart from the mounting surface, but the outer portion of the bent portion 26 is brought into close contact It is possible to prevent the elongating and contracting rod from being arbitrarily dislodged.
