Description

[Detailed Description of the Invention] This invention relates to a support device for folding and supporting a foldable basket along the ceiling of a gymnasium.

As a conventional technology, for example, the foldable basket support device described in Japanese Utility Model Publication No. 55-21711 has a structure in which, when the foldable basket is folded and supported along the ceiling when not in use,
It was necessary to wind the other end of the wire rope around the drum of the worm winder to prevent it from loosening.

This is because there is no means for determining or positioning the support position of the collapsible basket.

The purpose of this invention is to solve the above-mentioned disadvantages of the conventional technology, and the basket folded along the ceiling can be hung on the support hook as it is for support, and if necessary, it can be easily attached to the support hook. It is an object of the present invention to provide a support device having a structure that can be removed and deployed to a use state with a simple operation.

Next, this invention will be explained with reference to illustrated embodiments.

In Figures 1 and 2, 1 is a main pillar whose upper end is rotatably attached to the ceiling 2 of the gymnasium with a pin 3, and 4 is a pillar whose upper end is rotatably attached to the ceiling 2 with a pin 5. Reference numeral 5 denotes a support frame with a pack board 6 attached to its front side, and the lower ends of the main column 1 and column 4 are connected to the upper and lower parts of the frame with pins 7 and 8, respectively, thereby forming a foldable basket with a four-bar link structure. ing.

9 in the figure is a basket installed on the front side of the backboard 6.

Next, reference numeral 10 in FIG.
It is wound around the drum of a winder (not shown) on the left side of the figure.

In the figure, 12 is a support hook installed on the ceiling 2.

This support hook 12 is pivotally supported by a shaft pin at a position on the rotation locus of a horizontal bar 13 for latching on the main column 1.

As shown in FIG. 3, a control piece 15 is attached to the opening of the support hook 12, which is rotatable about the pin 14, opens and closes the opening, and allows the horizontal bar 13 to be engaged and disengaged. ing.

Next, the method of use and operation of the foldable basket support device having the above structure will be explained.

In order to fold and support the folding basket along the top valve portion 2 from the usage state shown in FIG. 1, the wire rope 10 is pulled to the left.

Then, the main pillars 1 and 4 rotate upward about the pins 3 and 5, and the support frame 5 and pack board 6 are folded while being tilted downward.

When the horizontal beam 13 of the main column 1 approaches the support hook 12, it rises as shown in FIG. 3A and pushes up the control piece 15 to open the opening.

Therefore, when the wire rope 10 is loosened a little when the horizontal bar 13 is slightly higher than the mouth of the support hook 12, the horizontal bar 13 falls into the mouth of the support hook 12 and becomes latched, and from then on, the wire rope 10 is Even if it is completely loosened, the foldable basket is reliably supported by the support hook 12 as it is.

Next, in order to unfold the folding basket from the unused state supported by the support hooks 12 as described above to the used state shown in FIG. 1, the wire rope 10 is first pulled to the left.

Then, the horizontal bar 13 is pulled up together with the main column 1, and the control piece 15 is pushed up to open the opening as shown in the middle opening of FIG. It rotates downward under the action of its own weight and closes the opening of the support hook 12.

After that, when the wire rope 10 is slowly loosened, the main column 1 and the support column 4 rotate counterclockwise in FIG. It descends as shown in the figure A, hits the outer surface of the control piece 15, pushes the support hook 12 laterally around the upper shaft pin 16 as a fulcrum, and descends, detaching from the support hook 12 and folding. A tatami-style basket will be developed.

As described above, the collapsible basket support device of this invention can reliably support the collapsible basket on the folding support hook along the ceiling simply by pulling the wire rope 10, or Moreover, it can be removed from the support hook and unfolded for use, making it extremely easy and convenient to use.
