Description

[Detailed Description of the Invention] The present invention relates to the structure of a device for rotatably connecting a horizontal member such as a shelf bracket to a column. A pair of upper and lower arcuate guides are attached to the inside of each of the plurality of holding bodies, while the guides are fitted from the outside of the support by being fitted into locking grooves drilled at appropriate intervals along the length of the support. The plurality of holding bodies are provided so as to surround the plurality of locking pieces and the outer periphery of the support column so as to wrap both upper and lower ends of the locking piece, so that they are rotatable with respect to the support support but cannot be removed. ,
By removably attaching the horizontal member to the holding body, the horizontal member can be connected to the support column so that the mounting height can be changed and the horizontal member can be rotated horizontally.

Next, the present invention will be explained based on an embodiment in which the present invention is applied to a display device. vertically elongated rectangular locking slots 3 are bored at appropriate intervals P along its longitudinal direction.

This locking groove hole 3 of an arbitrary height is configured so that a proximal claw of a bracket 5 for supporting the shelf board 4 can be fitted and locked therein.

The coupling device 6 in the embodiment includes a pair of locking pieces 7,
7, and a pair of holding bodies 8, 8 that hold both the locking pieces 7, 7 from the outside, each locking piece 7 having an arcuate cross section that can come into contact with the outer peripheral surface of the support column 1. One or two pawls 9 are provided which fit into and lock into the locking slot 3 of the support column 1 by bending it inwardly at one end or protruding from the inside as appropriate.

The holding bodies 8, 8 are each bent to have a U-shaped cross section, and the left and right ends of each holding body are bent outward and attached to the other side with bolts and nuts (not shown). A flange 10 may be provided, or one end of the two may be connected by a hinge, while the other end may be connected by inserting an upper and lower pin.

A pair of upper and lower guide pieces 11, 11 each having a semicircular or semicircular cross-section are fixed to the inside of the U-shaped groove of each holding member 8 at a distance substantially equal to the height of the locking piece 7.

At this time, the inner circumferential radius of each guide piece 11 is slightly larger than the outer circumferential radius of the column 1, so the inner circumferential surface of the guide piece 11 does not come into contact with the outer circumferential surface of the column, and the outer circumferential radius of the guide piece 11 is locked. The outer circumferential radius of the locking piece 7 should be slightly larger than that of the outer circumference of the locking piece 7, so that the outer circumference of the locking piece 7 does not come into contact with the inner surfaces of the holding bodies 8, 8.

Also, each of the holders 8, 8 has a flange 1 thereof.
A locking groove 1 having the same pitch and shape as the locking groove 3 in the support column, which opens in the protruding direction of 0 and 10 and in a direction perpendicular thereto, or in either one of them.
2. At this time, as shown in the figure, a rib 13 having a U-shaped cross section may be provided on the outer surface of the holding body 8, and a locking groove hole 12 may be provided in the rib 13.

In addition, at the end of the horizontal member 14 or the base end of the bracket 5, a locking pawl 15 is provided to project downward and fit into each of the locking slots 12 and 3 in the holding body 8 or the support column 1. .

With this configuration, the pair of locking pieces 7, 7 are inserted into the locking slot 3 in the middle of the support 1 which is removably fitted into the support 1 on the fixed stand 2 or the movable stand 16 with casters at the lower end. Fit each claw 9, 9 to hold the support from the outside, then both locking pieces 7, 7
Both holding bodies 8,
If 8 are connected with bolts etc., both holding bodies 8, 8
is fixed to the column 1 so as not to be able to move up and down, and also to be horizontally rotatable around the axis of the column 1, and as shown in FIG. 6 and the column 1 on the movable stand 16 are connected by the horizontal member 14, the movable stand 16 can change its left and right position, and therefore the display shelf 4 that spans between them can also change its left and right position. By having a plurality of brackets 5 protrude outward from the connecting device 6 and placing the shelf board 4 thereon, the shelf board 4 becomes horizontally rotatable around the axis of the support column 1. Furthermore, the mounting height positions of these coupling devices can be easily changed.

In the present invention, there may be two or more locking pieces 7 and holding bodies 8 surrounding the outer periphery of the support 1, and the support 1 may have a square cross section as shown in FIG. By forming the locking piece 7 in an arc shape such as a substantially semicircular shape, the holding body 8 can be rotatably mounted as in the previous embodiment. In addition, this invention has two
The present invention can also be applied to a case where the end members of the partition plate described above are rotatably attached via the pair of upper and lower connecting devices.

As described above, in the present invention, locking grooves are bored at appropriate intervals along the longitudinal direction of the support, and a plurality of locking pieces having an arcuate cross section that contact the outer periphery of the support have the following features:
Each of the claws protrudes inwardly, and the claws are inserted and locked into locking grooves of an appropriate height in the support, while a pair of upper and lower arcuate guide pieces is fixed to the inside of each of the plurality of holding bodies, The plurality of holding bodies are rotatably held and attached to the outside of the support column so that the upper and lower guide pieces surround the upper and lower ends of the plurality of locking pieces, and a horizontal member is attached to the holding body. It is equipped with a means for detachably attaching it, and since the locking piece and the holding body can be divided into multiple pieces, there is no need to fit it in from the top end along the axis of the column, and it can be attached to the protrusion already fixed to the middle part of the column. Even if there are facilities, the connecting device can be attached and detached at any height position, making the attachment and detachment work extremely easy.

Further, since the locking piece is located inside the holding body, it is not bulky, and the vertical height of the entire connecting device can be made small and compact.
