Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clothes rack.

[0002]

[Prior art]

 In a clothes rack of a type in which circular pipes are connected and assembled, conventionally, the circular pipes are connected by welding.

[0003]

[Problems to be solved by the device]

 However, when assembling the clothes rack, there is a problem that the work environment deteriorates due to the welding work, and further, there is a problem that the work efficiency deteriorates because the assembly takes time.

Therefore, an object of the present invention is to provide a clothes rack that solves the above-mentioned conventional problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a clothes rack in which a plurality of circular pipes are connected through a connecting member, wherein the connecting member has a male screw on the outer circumference and a tip end diameter expansion at the front end. Cylindrical portion for inserting a circular pipe having a tapered surface, a cap nut screwed to the male screw and having a reverse taper surface facing the taper surface, and an interposition between the reverse taper surface and the taper surface. The reverse taper surface, the taper surface, and an elastic ring that press-contacts the circular pipe to connect the circular pipe and the cylindrical portion are provided.

[0006]

[Action]

 By inserting an elastic ring between the tapered surface and the reverse taper surface, inserting the circular pipe through the tubular part, the elastic ring and the cap nut, and tightening the cap nut screwed to the male screw of the tubular part, The elastic ring is sandwiched between the taper surface and the reverse taper surface, elastically deforms, and is pushed inward, pressed against the outer peripheral surface, the tapered surface, and the reverse taper surface of the circular pipe, and the circular pipe is connected to the tubular portion. To be done.

As described above, since the circular pipes can be connected and assembled with only the connecting member, the welding work becomes unnecessary and the working environment is improved. Moreover, since the assembling is easy, the workability is good, and the assembling on the user side is also possible.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment.

1 and 2 show a clothes rack according to the present invention. The clothes rack has a plurality of circular pipes 2 ... Connected via respective connecting members 1 ... The clothes can be hung from the pair of front and rear upper circular pipes 2a, 2a connected by the L-shaped connecting members 1a through the connecting members 1b through the hanger or the like.

Further, a pair of left and right U-shaped connecting members 1c, 1c provided with casters 3 are fitted with connecting members 1d with a collar, and through I-shaped connecting members 1b. A pair of front and rear lower circular pipes 2b, 2b are connected.

Further, the vertical circular pipes 2c ... Are connected by the connecting members 1a ... And the connecting members 1c, 1c via the pair of left and right H-shaped connecting members 1e, 1e.

As shown in FIG. 3, each connecting member 1 has a tubular portion 5, a cap nut 6 and an elastic ring 7 formed in the connecting member body 4 (see FIGS. 1 and 2). There is.

The cylindrical portion 5 has a male screw 8 of a predetermined length on the outer periphery thereof and a hole portion 9 through which the circular pipe 2 can be inserted.

Further, a tapered surface 10 having a diameter-expanded tip is formed at the tip of the tubular portion 5 at a predetermined inclination angle θ 1 ─, for example, 30 ° to 60 °.

The cap nut 6 has a female screw 14 to be screwed into the male screw 8 on its inner peripheral surface and a short hole portion 11 into which the circular pipe 2 can be inserted.

Further, the inner flange portion 12 of the cap nut 6 has a reverse taper surface 13 facing the taper surface 10 and having a diameter reduced from the female screw 14 side toward the short hole portion 11 side at a predetermined inclination angle θ2. ─── For example, it is formed at 30 ° to 60 °.

As shown in FIGS. 4 and 5, the circular pipe 2, the tubular portion 5, the cap nut 6 and the elastic ring 7 are assembled, and the circular pipe 2 is attached to the tubular portion 5 (connecting member 1). Be connected.

Specifically, as shown in FIG. 4, the circular pipe 2 is inserted into the short hole portion 11, the elastic ring 7 and the hole portion 9, and the male screw 8 of the tubular portion 5 is fitted with the female screw 14 of the cap nut 6. The elastic ring 7 is mounted between the taper surface 10 and the reverse taper surface 13 by screwing.

When the cap nut 6 is screwed and tightened, the elastic ring 7 is elastically deformed by being sandwiched between the tapered surface 10 and the reverse tapered surface 13, as shown in FIG.

At this time, since the gap formed by the tapered surface 10 and the reverse taper surface 13 has a shape that widens in the inner diameter direction, the elastic ring 7 is pushed in the inner diameter direction and is pushed out of the circular pipe 2. The circular pipe 2 is press-contacted with the peripheral surface, the tapered surface 10 and the reverse tapered surface 13, and the circular pipe 2 is connected to the tubular portion 5 (connecting member 1).

FIG. 6 shows a case where the small-diameter circular pipe 2 d is connected to the connecting member 1 by using the sleeve 15.

The outer peripheral surface 16 of the cylindrical portion and the outer surface 17 of the outer flange portion of the sleeve 15 are formed so that they can be fitted into the hole 9 and the taper surface 10 of the tubular portion 5, and the inner surface 18 of the outer flange portion is a tapered surface. It is formed with the same inclination angle as 10.

In this case, the elastic ring 7 (on the upper side in the figure) is interposed between the inner surface 18 of the outer collar portion and the reverse taper surface 13, and the elastic ring 7 is fixed to the circular pipe 2d by fastening the cap nut 6. The circular pipe 2d is connected to the cylindrical portion 5 (on the upper side in the figure) by being pressed against the outer peripheral surface, the inner surface 18 of the outer flange portion and the reverse taper surface 13.

Further, by inserting the small-diameter circular pipe 2d into the large-diameter circular pipe 2e (on the lower side in the figure), for example, by using the connecting member 1b or the connecting member 1e shown in FIG. If the circular pipes 2d and 2e are connected as shown in the figure, the bag nut 6 fastened to the tubular portion 5 (upper side in the figure) is loosened, and the small diameter circular pipe 2d is slid to move the clothes rack up and down and left and right. The right length can be adjusted.

[0025]

[Effect of device]

 Since the present invention is constructed as described above, it has a great effect as described below.

An elastic ring 7 is interposed between the tapered surface 10 and the reverse tapered surface 13, and the circular pipe 2 is inserted into the tubular portion 5, the elastic ring 7 and the cap nut 6 and screwed to the tubular portion 5. The circular pipe 2 can be connected to the connecting member 1 only by tightening the cap nut 6.

In this way, since the circular pipes 2 can be connected and assembled with only the connecting member 1, welding work is unnecessary and the working environment is improved. Moreover, since the assembling is easy, the workability is good, and the assembling on the user side is also possible.
