Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a hanging device for hanging a frame or the like.

[Conventional technology]

When hanging a picture frame or the like using a string hanging from the ceiling, it is extremely time consuming to tie and untie the string to adjust the height.

Therefore, a wire or wire is hung down from the ceiling, a slider passing through the wire or wire is slid, and then a screw on the slider is screwed in to stop the slider relative to the wire or wire.

[Problem that the invention attempts to solve]

Since the screws are loosened and tightened using a screwdriver, a tool is required and there is a problem in that adjustments cannot be made easily and quickly.

Additionally, if the screws were not tightened enough, there was a problem that the slider would descend.

[Means for solving problems]

In order to solve the above problems, this invention includes a base body having a hook part, a vertical through hole provided at the center of this base body, and a body that is inserted into the through hole, and
A cylindrical body provided to rotate in a fixed position, a ball chain inserted into the cylindrical body, a through hole provided in the peripheral wall of the cylindrical body, and a part of the ball chain fitted into the through hole so as to fit between the balls of the ball chain. It consists of a ball inserted into the hole, a recessed hole provided in the peripheral wall of the through hole so that the ball can escape when it matches the through hole as the cylinder rotates, and an elastic member built into the recessed hole to push the ball back. It is.

[Effect]

The upper end of the ball chain is supported by a ceiling or the like, and a frame or the like is hung from the hanging part of the base.

To adjust the height of the hanging frame, first rotate the cylindrical body to align the through hole with the recessed hole.

Next, when you slide the base upward or downward,
The ball of the ball chain pushes the ball back from inside the through hole toward the recessed hole, and the base body slides with respect to the ball chain.

After the base body stops sliding, the ball is pushed back into the through hole by the elastic member and the ball fits between the balls of the ball chain, so that the base body stops sliding with respect to the ball chain.

However, when the cylinder is rotated so that the through hole is in a mismatched state with respect to the recessed hole, the ball comes into contact with the hole wall of the through hole, preventing the ball from escaping, so that the base body slides relative to the ball chain. will definitely stop.

〔Example〕

In the figure, 1 is a base body having a hanging part 2 for hanging a frame or the like.

In the illustrated case, the above-mentioned hook 2 is provided with a hook extending from the lower end of the cover 4 which is placed over the base 1 from below and secured with screws 3, but it may be a ring or the like other than a hook.

5 is a vertical through hole provided at the center of the base 1;
A cylindrical body 6 that rotates at a fixed position is fitted into the through hole 5.

A ball chain 7 is inserted through the cylindrical body 6, and the upper end of the ball chain 7 is supported on the ceiling or other appropriate place.

Reference numeral 8 denotes a through hole provided in the peripheral wall of the cylindrical body 6.

In the illustrated case, the above-mentioned through holes 8 are arranged in two locations on the left and right.

Further, a ball 9 whose outer circumference partially fits between the balls of the ball chain 7 is fitted into the above-mentioned through hole 8 .

Furthermore, a recessed hole 10 is provided in the peripheral wall of the through hole 5, into which the ball 9 escapes when it matches the through hole 8, and an elastic member 11 that pushes the ball 9 back is incorporated in the recessed hole 10.

In the illustrated case, by using a coil spring as the elastic member 11 and disposing the ball 12 on the front side of the elastic member 11, smooth rotation of the cylindrical body 6 can be ensured.

Furthermore, by providing a V-groove 13 between the outer peripheral through-holes 8 of the cylindrical body 6, the ball 12 fits into the V-groove 13, thereby determining the stop position of the cylindrical body 6 and connecting the through-hole 8 and the recessed hole 10. The state of the discrepancy can be known.

14 in the figure is a photograph provided at the upper end of the cylinder body 6.

Next, stopping and unstopping of the base body 1 with respect to the ball chain 7 will be explained.

First, rotate the cylinder 6 by 90 degrees to fit the through hole 8 into the recessed hole 10 (as shown in Figures 2 and 3).
Then, when the base body 1 is slid upward or downward relative to the ball chain 7, the balls of the ball chain 7 push the ball 9 back from the through hole 8 into the recessed hole 10, as shown in FIG. , the base 1 slides.

When the base body 1 stops sliding, the balls 10 are pushed back by the elastic member 11, so the balls 9 fit between the balls of the ball chain 7.

When the cylindrical body 6 is rotated by 90 degrees after the base body 1 stops sliding (as shown in FIG. 6), the through hole 8 becomes mismatched with the recessed hole 10, and
Since the ball 9 in the through hole 8 is prevented from escaping by the hole wall, the ball chain 7 is prevented from escaping as shown in FIG.
A part of the outer periphery of the ball 9 fits between the balls, and the sliding of the base 1 with respect to the ball chain 7 is stopped.

〔effect〕

As mentioned above, according to the hanging device according to this invention,
By rotating the cylinder and aligning the through hole with the recessed hole,
Sliding of the base body relative to the ball chain is enabled, and sliding of the base body relative to the ball chain is prevented by rotating the cylinder so that the through hole is misaligned with the recessed hole.

Therefore, the height of the base can be freely adjusted easily and quickly.
