Description

The present invention relates to an end cap for a pipe that is attached to an opening of the pipe.

Hanger pipe devices are often used when displaying and storing clothing. As this hanger pipe device, a pipe that engages the hooks of each hanger bracket with the engagement holes provided in each of the pair of columns and hangs the hanger or the like in the openings provided at the tips of these hanger brackets. Is known to have been inserted and attached.

End caps for pipes are attached to the openings at both ends of the inserted pipe to improve the design and prevent the user from being injured by the tip of the pipe.

Patent Document 1 proposes an end cap to be attached to the tip of a display pipe for cosmetic purposes. This end cap will be described with reference to FIG. The end cap 100 includes a cap 101 provided with a screw 101a, and a cylinder quadrant 104 obtained by dividing a resin elastic cylinder into four. A gradient hole is provided in the inner hole of the cylindrical quadrant 104, and the ball 107 is inserted into the gradient hole 104a. A square nut 108 into which a screw 101a is screwed is provided in the inner hole of the cylindrical quadrant 104. The end cap 100 is formed by screwing the screw 101a of the cap 101 into the square nut 108.

By inserting the end cap 100 into the pipe 109 and pressing the ball 107 with the screw 101a, the ball 107 is pushed out in the direction of the arrow, and the cylindrical quadrant 104 is expanded in the direction of the arrow to spread the inner surface of the pipe 109. By pressing, the end cap 100 is attached to the pipe 109.

Embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals, and the explanations are not repeated in order to avoid duplication of explanations.

The pipe end cap 1 of the present invention is used in a hanger pipe device as shown in FIGS. 6 and 7. A plurality of slits 91 are provided in the support column 9 fixed to a wall or the like, and an engaging hook (not shown) provided at the rear end of the hanger bracket 7 is inserted into the slits 91 for mounting. Then, the pipe 8 is inserted into the opening of the hanger bracket 7 and used as a hanger pipe device.

Further, a retaining tool 71 is attached to the hanger bracket 7 to prevent a part of the retaining tool 71 from entering between the slit 91 and the engaging hook to prevent the hanger bracket 7 from falling off from the support column 9. ing.

As shown in FIGS. 6 and 7, the pipe end cap 1 of the present invention is attached to the openings 81 at both ends of the pipe 8 inserted into the openings of the hanger bracket 7.

The end cap 1 for a pipe is composed of a metal disk-shaped cap 10, a bolt portion 11 fixed to the central portion of the cap 10, a saucer 12, a nut portion 13, an inner wall pressing member 14, a washer 15, and a mounting screw 16. Has been done.

The saucer 12 has a central hole portion 12a into which the bolt portion 11 is inserted, a central peripheral edge portion 12b rising from the peripheral edge of the central hole portion 12a, and an outer peripheral peripheral edge portion 12c rising from the outer periphery. The outer diameter of the outer peripheral peripheral edge portion 12c is formed to be slightly smaller than the inner diameter of the pipe 8.

The bolt portion 11 of the cap 10 is inserted into the central hole portion 12a of the saucer 12, and the saucer 12 is attached to the cap 10. The saucer 12 is pressed toward the cap 10 side by the tip portion 14b of the leg portion 14a of the inner wall pressing member 14, which will be described later.

As shown in FIGS. 1 to 3, the inner wall pressing member 14 has three legs 14a arranged at equal intervals in the circumferential direction. A guide tongue piece 14c is provided between the legs 14a and 14a. The inner wall pressing member 14 is formed of a spring material, and three leg portions 14a are bent forward from the rear end portion 14e provided with a hole 14d into which the mounting screw 16 is inserted in the central portion. The guide tongue piece 14c is formed so as to project in the circumferential direction from the rear end portion 14e. The guide tongue piece 14c is formed in a size that does not abut on the inner diameter surface of the pipe 8.

The leg portion 14a is first bent in a direction orthogonal to the rear end portion 14e, and then is bent toward the tip end in a "he" shape in which the vicinity of the central portion bulges outward. The tip portion 14b is bent inward from the leg portion 14a, and the tip portion 14b is formed so as to be parallel to the receiving surface 12d of the saucer 12.

In the pipe end cap 1, the nut portion 13 is inserted into the leg portion 14a of the inner wall pressing member 14, one end of the nut portion 13 is brought into contact with the rear end portion 14e, and the screw 16 is inserted into the nut portion via the washer 15. Screw into. The nut portion 13 is attached to the inner wall pressing member 14 by the nut portion 13 and the screw 16. Then, the bolt portion 11 to which the saucer 12 is attached is screwed into the other end of the nut portion 13, and the pipe end cap 1 is assembled.

The outermost bulging portion of the leg portion 14a of the inner wall pressing member 14 of the assembled pipe end cap 1, that is, the apex portion of the “he” shape is formed to be slightly larger than the inner diameter of the pipe 8.

As shown in FIG. 3, the pipe end cap 1 thus configured is inserted through the opening 81 of the pipe 8. At this time, the leg portion 14a is slightly bent in the inner diameter direction and inserted. When the cap 10 of the pipe end cap 1 is turned in this state, the nut portion 13 and the rear end portion 14e of the inner wall pressing member 14 are moved in the direction of the cap 10 by the bolt portion 11 and the nut portion 13. Due to this movement, the leg portion 14a of the inner wall pressing member 14 contracts in the axial direction, and a force is applied to expand the leg portion 14a to the outside. As a result, the leg portion 14a and the inner diameter surface 82 of the pipe 8 are firmly pressed. Then, as shown in FIG. 4, the tip portion 14b of the leg portion 14a comes into contact with the central peripheral edge portion 12b of the saucer 12, and the reaction force from this position causes the leg portion 14a to come into contact with the inner diameter surface 82 of the pipe 8. The contact force is maintained, and the pipe end cap 1 is firmly attached to the opening 81 of the pipe 8.

Further, when removing the end cap 1 for the pipe, the cap 10 is turned in the direction of loosening the bolt portion 11. The bolt portion 11 and the nut portion 13 move the nut portion 13 and the rear end portion 14e of the inner wall pressing member 14 in a direction away from the cap 10. By this movement, the leg portion 14a of the inner wall pressing member 14 extends in the axial direction, the contact force of the inner wall pressing member 14 can be weakened, and the pipe end cap 1 can be removed from the pipe 8.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is shown by the claims rather than the description of the embodiments described above, and is intended to include all modifications within the meaning and scope equivalent to the claims.
