Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of a closet door panel, and more particularly to a structure of a closet door panel which is lightweight, strong, and has a good appearance.

[0002]

[Prior art]

 As a conventional closet door panel, a panel that is entirely made of wood or covered with a metal plate only on the surface and is a hollow panel has been mainly used.

As shown in FIG. 3, in a conventional closet door, a plurality of panels 8 are connected by a hinge or the like, and a roller 7 provided at the center of the upper end of each panel is rolled into the rail 6. It can be freely inserted and suspended, and can be folded open and closed.

[0004]

[Problems to be solved by the invention]

 If the entire closet door panel is made of thick wood, it is preferable because it gives a magnificent feeling, but it becomes heavier as a whole, and as a result, there is a problem of cost due to the use of tough members such as rails and rollers. . In addition, when a metal plate such as a hollow iron plate is used, there is a problem that the hitting sound is poor and the sense of quality is impaired.

The present invention has been made in view of the above circumstances, and has as its object to provide a structure of a closet door panel that is lightweight, has high strength, and has a good appearance.

[0006]

[Means for Solving the Problems]

 The present invention has the following features to attain the above object. That is, the structure of the closet door panel according to the present invention includes a plurality of cross rails having holes communicating with the inside of the door panel on the upper surface and the lower surface of the door panel, and having a pair of cuts on one side. A front side metal plate that covers most of the side surfaces of the plurality of horizontal rails and has a bent portion that engages with a pair of cuts provided on one side surface of the horizontal rails, and a left side surface portion. A back-side metal plate having a bent portion that covers and engages with a pair of cuts provided on one side surface of the cross rail, and wherein the interior of the door panel is filled with a synthetic resin foam; Further, the horizontal rail is provided on an intermediate surface, and the synthetic resin foam is urethane foam.

[Embodiment of the invention]

 Hereinafter, the structure of the closet door panel according to the present invention will be described in detail with reference to the drawings. 1 is a perspective view of a closet door panel having the structure of the present invention, FIG. 2 is a partially cutaway perspective view of the closet door panel having the structure of the present invention as viewed from the back side, and FIG. It is a perspective view. In the drawing, reference numeral 1 denotes a front side metal plate, 1a denotes a bent portion, 2 denotes a back side metal plate, 2a denotes a bent portion, 3 denotes a horizontal bar, 3a denotes a hole, 3b denotes a cut, 4 denotes a synthetic resin foam, and 5 denotes a synthetic resin foam. The hinge, 6 is a rail, 7 is a roller, and 8 is a panel.

As shown in FIGS. 1 and 2, the structure of the closet door panel according to the present invention comprises a cross beam 3 having a hole 3a leading to the inside of the panel and a pair of cuts 3b, 3b on one side. 3 and the bent portions 1a, 1a which cover most of the side surfaces of the cross bars 3, 3 and engage with the cuts 3b, 3b, respectively, and most of the side surfaces of the plurality of cross bars 3, 3 are provided. A metal plate 1 covering the front side, a metal plate 2 on the back side having bent portions 2a, 2a covering the remaining side surfaces and engaging with the cuts 3b, 3b, and a synthetic resin foam 4 filling the internal space. It has the configuration shown.

A closet door panel generally comprises a plurality of door panels, and as shown in FIG. 1, the closet is opened and closed by a plurality of hinges 5 and 5 so as to be freely bendable. As shown in FIG. 3, a rail 6 is mounted on the upper side of the closet, and rollers 7, 7 mounted on the upper side of the door panel are inserted into the rail. The door panels 8, 8 can be opened and closed freely, or a support shaft (not shown) is provided on one side of the closet, and the end of one door panel is supported by the shaft.

In order to manufacture the closet door panel according to the present invention, first, a plurality of cross rails 3 are prepared. The material of the horizontal rail is preferably wood, and the side surface is processed into a predetermined shape, holes 3a, 3a for injecting resin are drilled, and the bent portions 1a, 1a of the front metal plate 1 and the back metal plate 2 Are provided with cuts 3b and 3b that engage with the bent portions 2a and 2a. The horizontal rails 3, 3 are placed at positions at least at the upper end and the lower end of the closet door panel, and one bent portion 1a of the front side metal plate 1 is engaged with one notch 3b. The front side is turned to engage the other cut 3b. Next, by engaging the bent portions 2a, 2a of the back side metal plate 2 with the same cuts 3b, 3b, a door panel having a hollow inside is formed. As the material of the metal plate, an iron plate or an aluminum plate can be used.

Next, the synthetic resin foam 4 is filled. The synthetic resin used for the synthetic resin foam is not particularly limited, and a known synthetic resin can be used. Typically, a phenol resin or a urethane resin can be used. In particular, the liquid A composed of polymeric isocyanate and the liquid B commonly known as urethane resin are maintained at appropriate pressure and temperature, and the liquid A and the liquid A are connected through a gun connected to a hose outlet for each liquid. When the liquid B is mixed at a fixed ratio and injected or injected through the hole 3a of the horizontal rail 3, the liquid 2 passes through the holes 3a, 3a,. It can be solidified in a foamed state throughout the part. The density of the foam can be adjusted by the mixing ratio of the A liquid and the B liquid, and the solidification rate can be adjusted by the temperature of the A liquid and the B liquid.

[Effect of the invention]

 1) According to the structure of the closet door panel of the present invention, despite being composed only of a plurality of cross rails, a metal plate on the surface, and a synthetic resin foam to be filled in the cavity, it is light in weight. A closet door panel having high strength and good appearance can be provided. 2) According to the structure of the closet door panel of the present invention, it is possible to provide closet door panels having various shapes only by changing the side shape of the horizontal rail. 3) According to the structure of the closet door panel of the present invention, a high-quality door panel can be easily manufactured because few members are required.
