Description

  The present invention relates to a length adjusting tool for an elastic pipe, an elastic pipe using the same, and a hanger rack for hanging clothes using the same.

  Conventionally, there is a hanger hanger for hanging a hanger on which clothes are hung (see paragraph number 0002 in the specification of Patent Document 1). This conventional hanger hanger has a structure in which two pipe-made struts erected on both ends of a base, and one pipe-shaped reed is passed between the upper ends of these struts.

  There is also known a parallel bar type hanger hanger in which two horizontal rods are arranged in parallel at the upper ends of four support columns respectively erected at the four corners of a base assembled in a rectangular shape.

  Furthermore, a hanger hanger has been proposed in which one bar is diagonally passed between the upper ends of two columns having different heights, and the upper surface of the bar is formed in a saw-tooth shape (Houseware Newspaper, 1993). September 1 issue, edited by Household Goods Newspaper Co., Ltd.). These hangers are usually prefabricated for convenient storage and transportation. In order to adjust the height and width according to the installation space at the time of assembly, the struts and reeds are configured to be extendable and retractable with double pipes and equipped with means for locking the slides of both pipes (hereinafter referred to as this Such a pipe is called "expandable pipe").

  In the conventional hanger hanger (hereinafter referred to as “conventional hanger hanger”) capable of adjusting the height and width described above, the invention has been invented to improve the problems that the length adjustment is troublesome and requires a relatively large space. The hanger hanger described in Patent Document 1. Certainly, the hanger hanger has solved the above-mentioned problems of the conventional hanger hanger. However, the hanger hanger is still widely used at home and stores such as department stores in terms of appearance and usability.

  The expansion and contraction pipe in this conventional hanger hanger is attached to the outer cylinder pipe by slidably inserting another pipe (hereinafter referred to as “inner pipe”) into the cylindrical pipe (hereinafter referred to as “outer cylinder pipe”). By tightening the screw, the inner pipe is supported by the screw.

  If such a stretchable pipe is used for the hanger, the height and width can be adjusted, making it easier to use. On the other hand, when the inner pipe is supported by a screw, the inner pipe is damaged by the tip of the screw. The problem that becomes worse.

  In some cases, a screw hole is provided in the inner pipe in advance in order to eliminate such a scratch caused by the screw, and the height is adjusted or the width is adjusted by inserting the screw into the screw hole (see Patent Document 2).

  However, if a screw hole is provided in the inner pipe in advance as described above, the screw hole itself does not look good, and there is a problem that height adjustment or width adjustment can be performed only at the position where the screw hole is provided. .

  Further, when the inner pipe is slid, there is a problem that the surface of the inner pipe is scratched (hereinafter referred to as “sliding scratch”).

It is. 4 (a) and 4 (c), the drawing is complicated, so that the inner pipe is omitted, and in FIGS. 4 (b) and (d), how the length of the inner pipe is adjusted. The inner pipe is also shown in a simplified manner to clearly indicate whether it is supported in the outer pipe. 1 to 4, an embodiment in which the present invention is applied to a hanger rack that is a hanger rack for hanging a hanger on which clothes are suspended will be described in detail.

  As shown in FIG. 1, two oppositely disposed support columns 2, 2, and a hanger hanging pipe for hanging a hanger, which is suspended on one end side of the two support columns 2, 2 and clothes are suspended 6 and the other end side of the two support columns 2 and 2 and a horizontal pipe 7 that is horizontally mounted between the two support columns 2 and 2. Caster pipes 8 having casters 9 and 9 attached in the vicinity of both ends are connected to each of the support columns 2 and 2 at right angles.

  Each pipe in the present embodiment is a steel pipe that has been subjected to unichrome plating, and each pipe is joined by welding. However, the material is not limited to this.

  The support column 2 is composed of an expandable pipe composed of an outer cylinder pipe 3 and an inner pipe 4 slidably inserted into the outer cylinder pipe 3, and the inner pipe 4 is screwed to one end side of the outer cylinder pipe 3. Thus, a length adjusting tool 5 capable of adjusting the length of the column 2 is attached.

  The length adjuster 5 is formed in a cylindrical shape, and includes a main body 51 having a screw hole 511 and an annular groove 512 formed in an annular shape on the inner peripheral surface so as to include the screw hole 511, and the screw hole 511. And a shock-absorbing member 52 made of a rubber material or synthetic resin and attached to the annular groove 512 in an annular shape.

  Further, a fitting portion 513 for fitting the outer cylinder pipe 3 is provided on one end side (lower side in FIG. 3) of the main body 51, and the outer cylinder pipe 3 is fitted into the fitting portion 513. It is joined to the main body 51 by attaching, welding or the like.

  The buffer member 52 is a substantially C-shaped member that is attached to the annular groove 512 in a state where the bottom of the annular groove 512 is urged, and that has a gap portion 521 in part when attached to the annular groove 512. . That is, the buffer member 52 is not a continuous annular member when attached to the annular groove 512 but a member having a discontinuous gap 521 in a part thereof.

  In the present embodiment, as shown in FIG. 3, the buffer member 52 is a C-shaped member having a diameter larger than the inner diameter of the main body 51, but is not limited thereto. As described above, the buffer member 52 only needs to be attached to the annular groove 512 so as to urge the bottom of the annular groove 512 and to have a gap 521 in a part thereof. The ring groove 512 may be rounded and attached.

  As described above, the annular groove 512 is provided so as to include the screw hole 511, that is, the screw hole 511 has an opening at the bottom of the annular groove 512 from the outer peripheral surface of the main body 51 to the inner peripheral surface. It is a hole penetrating through. Therefore, when the male screw 53 screwed into the screw hole 511 is tightened, the tip portion 531 of the male screw 53 presses the buffer member 52 from the outer peripheral side.

  In the present embodiment, the buffer member 52 protrudes in the center direction from the inner peripheral surface of the main body 51 in a state of being attached to the annular groove 512. That is, when the buffer member 52 is attached to the annular groove 512, the buffer member 52 is not flush with the inner peripheral surface of the main body 51 but protrudes from the inner peripheral surface. By configuring in this way, it is possible to prevent the inner pipe 4 and the inner peripheral surface of the main body 51 from rubbing, and it is possible to prevent sliding scratches when the inner pipe 4 is slid.

  In the present embodiment, the buffer member 52 is configured to protrude from the inner peripheral surface of the main body 51 as described above in order to prevent slide scratches generated on the inner pipe 4 surface. However, it is possible to prevent the slide flaw on the surface of the inner pipe 4.

  As will be described later, when the male screw 53 is tightened, the diameter of the buffer member 52 is reduced, and as a result, the inner surface of the buffer member 52 protrudes from the inner peripheral surface of the main body 51. Because. Accordingly, before the inner pipe 4 is slid, the male screw 53 is tightened in advance so that the inner surface of the buffer member 42 does not contact the inner pipe 4 and is slidable. If the 4 is slid, the buffer member 52 can sufficiently prevent the inner peripheral surface of the main body 51 and the inner pipe 4 from rubbing.

  A length adjustment structure in the hanger rack 1 configured as described above will be described with reference to FIG.

  The state shown in FIGS. 4A and 4B is a state before the inner pipe 4 is slid (hereinafter referred to as “initial state”), and the length adjuster 5 and the inner pipe 4 in the outer cylinder pipe 3 are slid. It is possible.

  On the other hand, the state shown in FIGS. 4C and 4D is a state in which the inner pipe 4 is positioned in the length adjuster 5 and the outer cylinder pipe 3 and supported by screws (hereinafter referred to as “supported state”). . Each state will be described in detail below.

  The initial state in the present embodiment is a state in which the tip 531 of the male screw 53 is not in contact with or pressed against the outer peripheral surface of the buffer member 52. In this state, the width of the gap portion 521 of the buffer member 52 is in the same state as that attached to the annular groove 512, and the inner pipe 4 is slidable within the length adjuster 5 and the outer cylinder pipe 3. It has become.

  In this initial state, it is only necessary that the inner pipe 4 is slidable within the length adjuster 5 and the outer cylinder pipe 3, so that the tip 531 of the male screw 53 contacts the outer peripheral surface of the buffer member 52. It may be in a state where the outer peripheral surface is pressed and the width of the gap portion 521 is reduced, and the inner pipe 4 is slidable within the length adjuster 5 and the outer cylinder pipe 3.

  If the inner pipe 4 is slid in such a state, it is not necessary to completely loosen the male screw 53, but the buffer member 52 should be protruded from the inner peripheral surface of the main body 51 of the length adjuster 5 in advance. Even if it is not, it is possible to prevent rubbing with the main body 51 that may occur when the inner pipe 4 is slid.

  When the user slides the inner pipe 4 in the length adjuster 5 and the outer pipe 3 from the initial state and moves the inner pipe 4 to a desired height, and then tightens the male screw 53, the inner pipe 4 Is supported by a length adjuster 5 with screws. More specifically, when the male screw 53 is tightened, the male screw 53 abuts from the outer peripheral surface side of the buffer member 52 and presses the buffer member 52 from the outer peripheral surface side. Then, the buffer member 52 that has received this pressing force has a force acting in the direction of the arrow in FIG. 4A, and as a result receives a force that is pressed against the side facing the screw hole 511, While decreasing, it acts to reduce its diameter.

  Then, the inner pipe 4 arranged in the buffer member 52 is supported by the buffer member 52 in an annular shape on the outer peripheral surface. That is, in the prior art, the inner pipe 4 is directly supported at one point by the tip portion 531 of the male screw 53. However, in the hanger rack 1 in the present embodiment, the buffer member 52 is connected to the annular groove in the length adjuster 5. The inner pipe 4 is supported in an annular shape by the buffer member 52 by being attached to the 512 as described above.

  Therefore, in the hanger rack 1 in the present embodiment, when adjusting the lengths of the columns 2 and 2, the tip portion 531 of the male screw 53 is not damaged, and further, it is not supported at a single point as in the prior art. Therefore, its supporting power will be strong.

  In the present embodiment, only the support columns 2 and 2 are the expansion and contraction pipes to which the buffer members 52 are attached as described above. In this case, the same scratch prevention effect as described above can be obtained.

  Further, in the present embodiment, only the case where the length adjusting tool of the stretchable pipe of the present invention or the stretchable pipe using the same is applied to the hanger rack has been described. The stretchable pipe that has been used is not only applied to the hanger rack, but can also be applied to various articles having a so-called double pipe structure in which the length is adjusted.

  Further, in the present embodiment, the material of each pipe has been described as being made of metal. However, the problem of scratches that occur when the inner pipe 4 is supported at one point by screwing is because the pipe is made of metal. Since the present invention is not limited, the structure of the present invention can be applied even when each pipe is formed of other materials.
