Description

  The present invention relates to a curtain support structure for closing a space below a rear portion of a top plate in a table.

2. Description of the Related Art Conventionally, in a folding table, a curtain plate support member is connected to a top plate or a leg, and the curtain plate is supported below the top plate by the curtain plate support member. There is one which is formed by being separated by a pair of left and right closing members which close both left and right ends of the curtain body (see Patent Document 1).
Japanese Patent No. 334595 (FIGS. 1 and 4)

  However, in the thing of the above-mentioned patent document 1, by fitting the insertion part of a closure member in the opening of each side end of the hollow plate-like curtain board main body which faces the right-and-left direction which both right and left ends open, Although each side end of the curtain plate body is closed, there is no means for directly securing the insertion portion from the curtain plate body, so the fitting of the insertion portion becomes loose, rattling, A gap may be formed between the closing member and the curtain plate body, which may make it unsightly.

  In view of the above-mentioned problems of the prior art, the present invention can easily and surely prevent the closing member from being detached from the curtain plate body by assembling the curtain plate support member. It is an object of the present invention to provide a support structure for a curtain plate in a table that can simplify the structure of the curtain and the curtain plate support member and improve the assembly workability.

According to the present invention, the above problem is solved as follows.
(1) A table configured to support a pair of left and right curtain plate support members connected to the legs or the top plate below the rear portion of the top plate supported by the legs so as to support both side ends of the curtain plate facing in the left-right direction. The curtain plate has a hollow plate-like curtain plate body facing in the horizontal direction where both left and right ends are open, and an insertion portion is fitted into each side end opening of the curtain plate body. By combining them, a closing member that closes each side end of the curtain plate body is provided, and fitting holes that are aligned with each other are provided in the insertion portion of each closing member and the front surface of the curtain plate body. By fitting a protrusion projecting from the rear surface of each curtain plate support member into the hole, the blocking member is prevented from coming off from the side end of the curtain plate body.

(2) In the above item (1), the top plate is pivotally attached to the upper part of the leg so that it can be rotated between the use position that is horizontal above the leg and the folding position that faces upward, and the curtain The plate is folded below the top plate in conjunction with the rotation of the top plate from the use position to the folding position.

(3) In the above item (1) or (2), an upward hook portion is formed on the projection of the curtain plate support member, and this hook portion is provided on the upper surface of the fitting hole in the insertion portion of the closing member. Lock in the recess.

(4) In any one of the above items (1) to (3), the curtain plate support member and the closing member are fastened by fastening means, and between the rear surface of the curtain plate support member and the front surface of the insertion portion in the closure member. Hold the front of the curtain plate body.

According to the present invention, the following effects can be achieved.
(A) According to the first aspect of the present invention, the insertion portion of the closing member is fitted into the opening of each side end of the hollow plate-like curtain plate body facing in the left-right direction where both left and right ends open. In addition, since each side end of the curtain plate body is closed, the curtain plate body can be used by being cut into an appropriate length each time by molding with an extrusion material. The width of the main body can be easily changed.
Further, by fitting a protrusion projecting on the rear surface of each curtain plate support member into a fitting hole provided so as to be aligned with the insertion portion of each closure member and the front surface of the curtain plate body, the closure member Is secured from the side edge of the curtain plate body, so that the curtain plate support member can be easily positioned with respect to the curtain plate, and a means for preventing the insertion portion of the closing member from being separately provided, There is no need for screwing or the like, and the closing member can be easily assembled to the curtain plate body.

(b) According to the second aspect of the present invention, it is possible to improve the storage efficiency when stacking the tables.

(c) According to the invention described in claim 3, an upward hook portion is formed on the projection of the curtain plate support member, and the hook portion is provided on the upper surface of the fitting hole in the insertion portion of the closing member. Since it is latched to the insertion portion, the curtain plate can be hooked and temporarily secured to the curtain plate support member, and the projection of the curtain plate support member is less likely to come off from the fitting hole.

(d) According to the invention described in claim 4, the curtain plate support member is arranged so as to hold the front portion of the curtain plate body between the rear surface of the curtain plate support member and the front surface of the insertion portion of the closing member. Since the closing member is fastened, attachment of the curtain plate support member to the curtain plate becomes strong.
