According to the aforesaid construction, the only continuous groove 19 of a certain width remains on the strut 1 from upper to lower ends thereof, and no unagreeable bolt hole or the like is left on the strut 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is of a type in which a top plate is supported by a plurality of mutually independent leg supports, and is suitably used in offices and the like. It is related to a desk.

BACKGROUND OF THE INVENTION Conventionally, as a desk of this kind, one in which the corner portions of a frame are supported by leg supports, and a top plate is mounted on the frame is known.

[Problems to be Solved by the Invention] By the way, in the case of such a structure, there is no side panel or front panel as a structural member, so if you want to hide the front side or side side of the desk, you need to use a special curtain plate. must be installed between the leg supports.

One possible way to install such a curtain plate is to suspend and support the upper edge of the curtain plate on a frame via a bracket, and to fix the lower end side to a leg support via a bracket.

However, if the bracket is fixed to the leg support with bolts or the like, the bolt holes will be exposed in the leg support when the curtain plate is removed and used. Since the leg support part is easily exposed to the gaze of the user and others,
If left as is, it will spoil the appearance. Therefore, it becomes necessary to hide the screw hole with a cap or the like. Moreover, in order to be able to attach curtain plates with various vertical dimensions, it is necessary to provide screw holes at various height positions of the leg supports, and this must be done in a way that does not spoil the appearance. Things become increasingly difficult.

The present invention aims to solve such problems.

[Means for Solving the Problems] In order to achieve the above objects, the present invention takes the following measures.

That is, in the desk according to the present invention, the lower end side of the curtain plate is supported by the leg support via the bracket, and the leg support has an opening edge at the inner edge portion narrower than the inside. The grooves are formed continuously in the vertical direction. The curtain plate is arranged between the leg supports in a suspended state. The thickness of the bracket is set such that the tip thereof can be inserted into the groove of the leg support and locked horizontally to a position of approximately 45 degrees with respect to the opening direction of the several structures. It is plate-shaped and has a slit that opens at the upper or lower edge at a portion of the distal end corresponding to the opening edge. and,
A bracket with a slit on the upper edge and a bracket with a slit on the lower edge are inserted orthogonally into the common groove, and the slit forming parts of both brackets are engaged from above and below, and the base of each bracket is inserted. It is characterized in that the end portions are fixed to the inner surfaces of two curtain plates that meet in the vicinity of the grooves, respectively, via fasteners.

When fixing only one curtain plate to a post, insert a bracket with a slit on the upper edge and a fixing clip with a slit on the lower edge into the common groove at right angles. The slit-forming portion of the bracket and the slit-forming portion of the fixing clip may be engaged from above and below, and the bracket may be fixed to the curtain plate by opening the fastener.

[Operation] With this kind of configuration, the tips of the two brackets are inserted separately into the grooves of the leg support, and then both brackets are slid along the grooves toward each other, and the slits are removed. Once the formations are engaged, both brackets cannot be pulled out of their grooves. In this state, if each of the brackets is fixed to the inner surface of the curtain plate, the two curtain plates will be fixed respectively.

When fixing only one curtain plate to the leg support, insert the tip of the bracket into the leg support, insert the fixing clip orthogonally to this bracket, and connect the slit forming part of the bracket with the fixing clip. By engaging the slit forming portion of the fixing clip from above and below, it is possible to prevent the bracket from coming off from the groove. In this state, if the base end of the bracket is fixed to the inner surface of the curtain plate, the curtain plate can be fixed to the leg support.

Therefore, if it is like this, the curtain plate 51.52
Even if it is removed, the leg support 1 only has a continuous groove 19 of a constant width extending from the upper end to the lower end, and no bolt holes or the like that look strange remain. Moreover, since the opening edge 19a of the groove 19 is narrower than the inside,
It is easy to design the furniture so that it does not spoil its appearance as a piece of furniture even if it is left as is without a cover or the like attached. Furthermore, the brackets 7+, 72, 73 can be slid up and down along the grooves 19 and can be set at desired positions, so there is no need to prepare a large number of screw holes in advance. In addition, curtain plates 5□, 5° having various vertical dimensions can be appropriately fixed at optimal positions.

Note that since the upper end portion of the curtain plate is supported by the top plate or frame, it is difficult for the line of sight to reach the suspended portion.

Therefore, any suitable means may be used to attach the upper end portion of the curtain plate without departing from the spirit of the present invention.

[Effects of the Invention] Since the present invention has the above-described configuration, the lower end of the curtain plate can be fixed easily and reliably, and even when the curtain plate is removed, screw holes can be inserted into the leg supports. There is no residue left behind, and the curtain plate can be easily attached and detached without having to attach or detach a cap or the like for concealing an unsightly part. Further, curtain plates of various sizes can be fixed to the leg support without having to prepare a large number of screw holes in advance, and changes in specifications can be easily and appropriately handled.
