Abstract

PURPOSE:To make long seasoning unnecessary and consequently manufacture bent member for furniture and household fixture suitable for mass-production by a method wherein fixing clads are fixed through fast-acting adhesive to the part of the internal corner part of the bend member and reinforcing cat bars are fixed through slow-acting adhesive to the remaining part of its internal corner. CONSTITUTION:When bent member 1 for shelving plate is required, a W-like bending groove 5 is cut longitudinally on the rear of a sheet-laminated base plate 4, which is produced by pasting polyvinyl chloride sheet 3 on the surface of the base plate 2, so as to apply slow-acting adhesive 6 into the bending groove 5. An L-shaped bent member 7 is produced by closing the bending groove 5 with a bending angle controlling jig. To one end part of the internal corner part 8 of the bend member 7, a short fixing cleats 10 having a right-angled triangular cross-section is bonded through fast-acting adhesive 9, while a long reinforcing cleat 12 is bonded through slow-acting adhesive 11 adjacent to the cleat. Simultaneously, a fixing cleat 10, a reinforcing cleat 12 and a fixing cleat 10 are bonded successively to the internal corner part 8. Since the fixing cleats 10 fix to the bent member 7 by the hardening of the fast-acting adhesive 9 just after the attaching operations of the cleats 10 and 12, the bent member can be stored, packed up and forwarded as a product immediately after its removal from a jig.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a folding member for fittings and furniture suitable for storage fittings such as closets, shelf boards for storage furniture, etc., and a method for manufacturing the same.

[Prior Art] Conventionally, as shown in FIG. 7, for example, a folding member for a shelf of furniture has a sheet-attached substrate 23 with a sheet 21 attached to the front surface and a bending groove 22 formed on the back surface. The bending groove 22 of the sheet-attached substrate 23 is closed with a slow-acting adhesive 24 to form an L-shaped bending member 25.
A single reinforcing triangular cat 27 extends over the entire length of the inner corner 26 of 5.
were adhered via a slow-acting adhesive 28.

[Problems to be Solved by the Invention] However, in the above-mentioned prior art, since the slow-acting adhesives 24 and 28 are used for closing the bending groove 22 and attaching the triangular cat 27, these slow-acting adhesives 24. 2
It takes time to fix the bending member 25 by curing the bending member 25, and therefore the bending member 25 must be left standing for a long time to cure together with a jig for regulating the bending member 25 to a predetermined bending angle. Moreover, in order to perform mass production, a large number of bending angle regulating jigs and curing spaces are required.

Furthermore, if a fast-acting adhesive is used in place of the slow-acting adhesive 24 and 28 described above, the fast-acting adhesive is expensive and costly, and it is difficult to sequentially apply it to the long bending groove 22. There is a problem in that the initially applied portion of the adhesive hardens, resulting in poor jointing of the bending grooves 22.

Therefore, the present invention aims to solve the problems of the prior art described above by providing a bending member for fittings and furniture that eliminates the need for long-time curing with the jig and is suitable for mass production, and a method for manufacturing the same. .

[Means for Solving the Problems] That is, the first invention is a sheet pasted substrate having a sheet pasted on the front surface and a bending groove provided on the back surface of the sheet-attached substrate. In the bending member that is joined to form an L-shape, a fixing cat is fixed to a part of the inner corner of the bending member via a quick-acting adhesive, and the other part of the inner corner is reinforced. The gist of the invention is a folding member for fittings and furniture, characterized in that a sheet is attached to the front surface using a slow-acting adhesive. Using a sheet pasted substrate provided with a bending groove, the bending groove of the sheet pasted substrate is closed with a slow-acting adhesive to form an L-shaped bending member, and an inner corner of the bending member is formed. A fixing cat is bonded to a part of the inner corner using a fast-acting adhesive, and a reinforcing cat is bonded to another part of the inner corner using a slow-acting adhesive. The gist of this article is a method of manufacturing the member.

As slow-acting adhesives to be applied to these inventions, adhesives that require several 10 minutes to 12 hours to harden, such as ethylene vinyl acetate, acrylic vinyl acetate, and vinyl acetate, are preferred; as quick-acting adhesives, ethylene butyl There are many types of adhesives, including hot-melt adhesives such as acrylate, polypropylene, polyethylene, and nylon (trademark), and moisture-curable adhesives such as incyanoacrylate, but adhesives that harden in 1 to 10 seconds (preferably 2 to 3 seconds) is suitable.

[Function] In the present invention, when the fixing triangular cat is attached to a part of the inner corner of the L-shaped bent member through a fast-acting adhesive during the manufacturing process, By closing the bending groove, the still unstable form of the L-shaped bending member is fixed by fixing the fixing cat by curing the fast-acting adhesive. On the other hand, the slow-acting adhesive of the bending groove and the slow-acting adhesive of the reinforcing cat gradually harden under the fixed L-shaped bending member of the above configuration, and the bending part of the L-shaped bending member gradually hardens. Improve strength.

[Embodiment] Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

In this example, a bending member 1 for a shelf board is obtained, and first, a W-shaped bending WIt 5 is formed along the longitudinal direction on the back surface of a sheet pasted substrate 4 with a vinyl chloride sheet 3 pasted on the surface of a substrate 2.
(See Figure 5).

Next, a slow-release adhesive 6 of vinyl acetate is applied to the bending groove 5.

Next, the bending groove 5 is closed using a bending angle regulating jig (not shown) to form the sheet pasted substrate 4 into an L-shaped bending member 7, and then this L-shaped bending member 7 is formed. A short fixing cat 10 with a right triangular cross section is adhered to one end of the inner corner 8 of the member 7 via a fast-acting adhesive 9, for example hot melt, and then,
A slow-release adhesive 1 is placed in the inner corner 8 adjacent to the fixing cat 10.
1. Glue the reinforcing cat 12 with a long right triangular cross section using vinyl acetate, for example, and then sequentially attach the fixing cat 10, the reinforcing cat 12, and the fixing cat 10 in the same manner as above.
and the above-mentioned fast-acting adhesive 9. It is adhered to the inner corner part 8 via the slow-acting adhesive 11 and the fast-acting adhesive 9, thus obtaining the shelf board bending member l in which the fixing cat lO is arranged at both ends and the center of the inner corner part 8 ( (See Figures 1 to 4).

The shelf board bending member 1 obtained in this way is the above-mentioned cat 10.
Immediately after the work is completed, the fixing cat 10 is fixed to the bending member 7 by the hardening of the fast-acting adhesive 9, and the bending member 7 is attached.
Since it maintains its shape, it is stored, packaged, shipped, etc. as a product immediately after being removed from the jig.

Note that the bending groove may be a multi-striped groove 13 as shown in FIG. 6, or a V-shaped groove (not shown) may be used. or,
The fixing cat and reinforcing cat may have a cross section such as a quadrangular shape outside the triangular shape on the upper side.

[Effects of the Invention] As described above, in the present invention, since the fixing cat which is bonded with a fast-acting adhesive and the reinforcing cat which is bonded with a slow-acting adhesive are used together, the fixing cat is attached immediately after the fixing cat is attached. The shape of the L-shaped bending member is fixed. Therefore, after manufacturing the bending member of the product, there is no need to cure it with a jig for a long time, making mass production easier, without requiring space for curing, and allowing storage, packaging, and shipping immediately after manufacturing. Since a slow-acting adhesive is used to close the bending groove and bond the reinforcing cat, unlike using a quick-acting adhesive for these, manufacturing is technically easy and production costs can be reduced. Further, when the bending member is used, the slow-acting adhesive has already hardened and contributes to maintaining the strength.

The second invention is further suitable for producing the above-mentioned bending member.
