To adjust the height of the hook arm (hanging tool).

JP 2005-279191 A

  In the above conventional example, when the inner pole (inner shaft) is lifted and rotated, and the projecting piece (locking pin) is engaged with another engaging hole (locking hole), the projecting piece (engaging pin) is engaged. Since the inner pole (inner shaft) is not pivoted in the direction in which the retaining pin engages with the engagement hole (locking hole), the inner pole (inner shaft) is returned during the height adjustment operation. If you let go of your hand, the protruding piece (locking pin) will not engage with the engaging hole (locking hole), and the inner pole (inner shaft) with the hook arm (hanging tool) will drop greatly. Therefore, there is a problem that it is dangerous, and the present invention aims to solve this problem.

  The present invention is for solving the above-described problem, and a support is attached to a support fixed to an attached body such as an eave heaven, and a hanging tool is provided to hang a clothes rack etc. on the lower part of the support. The strut has an outer cylinder and an inner shaft, and the inner shaft can be moved up and down and rotated with respect to the outer cylinder, and the height of a hanging tool attached to the inner shaft can be adjusted. In the support device, the inner shaft is provided with a groove-shaped limiting groove that is one step lower on the outer periphery and extends in the vertical direction, and an engaging member that is biased outward is provided so as to protrude and immerse, and the outer cylinder In the above, the inner circumference is projected to extend in the vertical direction, and is provided with a plurality of slidable and rotatable protrusions in the restriction groove, and a plurality of locking holes are provided at intervals in the vertical direction. The protrusion is rotatable with respect to the outer cylinder within a range in which the protrusion is relatively rotatable in the restriction groove, and one end edge of the restriction groove is the protrusion. In the state where it abuts against the edge of the one end, the engaging tool is in a rotational position where the locking hole is provided in the vertical direction, and when the engaging tool reaches a height position corresponding to the locking hole, the engaging tool is engaged. The engaging tool can be engaged with the locking hole by the biasing force, and when the engaging tool moves upward from the state in which the engaging tool is engaged with the locking hole, the engaging tool is released from the locking hole and the inner shaft is When the inner shaft is rotated and the other end edge of the restriction groove is brought into contact with the other end edge of the ridge, the engaging tool is rotated without the locking hole provided in the vertical direction. It is configured to be guided so that it can move up and down without engaging with the locking hole, and a return tool is provided on the upper part of the inner shaft so as to slidably contact the protrusion of the outer cylinder. Is a support device for clothespins, etc., characterized in that the inner shaft is rotationally biased to a rotational position where the engaging tool engages with the locking hole.

According to the present invention, in the middle of operating the height adjustment while holding the hook provided on the inner shaft, the hook is released at a rotation position where the hook does not engage with the locking hole. However, since the return biased tool rotates the inner shaft to the rotation position where the engaging tool engages with the locking hole, the next locking hole even if the inner shaft and the hanging tool fall. The engaging tool engages and stops at that position, and does not fall down to the lowermost part, so that the danger that the hanging tool hits the head can be drastically reduced.

  Further, when the height is adjusted, it is not necessary to consciously return the engaging tool to the pivot position where it engages with the locking hole, so that there is an effect that the operation can be smoothly performed with a natural feeling of operation.

  Furthermore, since the inner shaft is urged to rotate by the return tool even during use, there is an effect that the inner shaft is not rattled or generated with respect to the outer cylinder.

The contact protrusion 25 of the return tool 15 is brought into contact with the protruding edge of the protrusion 8 (the edge on the side where the locking holes 11... 11 are provided) The shaft 4 and the holder 6 at its upper end are inserted into the outer cylinder 3. The assembly is completed when the support 1 is attached to the upper end of the outer cylinder 3 and the hook 5 is attached to the lower end of the inner shaft 4. When the abutment protrusion 25 of the return tool 15 is brought into contact with the protruding edge of the ridge 8, the return spring 26 is charged, and the inner shaft 4 is engaged with the engagement tool 12 in the locking holes 11. It will be in the state where it is urged to turn in the direction of the turning position.

  The rotation position at which the engagement tool 12 engages with the locking holes 11... 11 is the positional relationship of the outer cylinder 3 and the inner shaft 4 in the rotation direction. ... 11 is a position on the same vertical line, and sometimes the engaging tool 12 is engaged with the locking hole 11 (see FIGS. 3 and 5). Although it may not be engaged with the stop hole 11 (see FIG. 4 and FIG. 6), if the engaging tool 12 is actually engaged with the locking hole 11 or if the inner shaft 4 moves up or down. The position in the rotational direction where the engaging tool 12 can engage with the locking hole 11 is said. Conversely, the rotation position at which the engagement tool 12 does not engage with the engagement holes 11... 11 is the engagement position between the outer cylinder 3 and the inner shaft 4 in the rotation direction. The holes 11... 11 are not located on the same vertical line, and the engaging tool 12 engages with the locking holes 11... 11 even if the inner shaft 4 is moved up and down as shown in FIG. This refers to the position in the rotational direction that is not.

  From the state in which the engaging portion 24 of the engaging tool 12 is engaged with the lower end edge of the uppermost locking hole 11 (see FIGS. 1, 2, 3 and 5), the holding tool 5 is held. When the inner shaft 4 is moved upward, the engaging tool 12 comes into contact with the upper end edge of the locking hole 11 and rotates inwardly against the spring 14 by the inclined surface, and is disengaged from the locking hole 11. (See FIGS. 4 and 6). In the state where the engagement portion 24 of the engagement tool 12 is engaged with the lower end edge of the locking hole 11, the engagement tool 12 is not covered and exposed by the cover 37 (FIGS. 3 and 5).
