Description

  The present invention relates to a door structure, and more particularly to an improvement of a door structure using a laminated material for a lateral frame member of the door.

As shown in FIGS. 6 to 7, the door is a generic name including two frame frames 2, 2, horizontal frames of the upper frame 3 a, the lower frame 3 b, and the middle rail 3 c (including a horizontal middle rail 3 d described later). In addition, when the glass window W is provided in the center, the vertical middle rails 2a and 2a and the horizontal middle rail 3d are provided.
Then, the end portions of the upper frame 3a, the lower frame 3b, the middle rails 3c, 3d are abutted against the side surfaces of the rod frames 2, 2, and are framed by fastening members 6 such as nails, wood screws, screws, bolts, tuckers, etc. The decorative plate 4 and the glass window W are attached to the frame member 10 thus framed.
By the way, as a material of the door frame member 10, a solid material or a laminated material has been conventionally used. However, in recent years, a laminated material has been used from the viewpoint of improving processing accuracy and protecting natural resources. It is coming.

  However, since the laminated material is a plywood obtained by laminating and adhering the single plates laminated and bonded in parallel to the fiber direction, when such a laminated material is used as the material of the door frame member 10, Although there is no particular problem in the strength in the length direction, the end face of the horizontal frame 3 is used when the frame frames 2 and 2 and the horizontal frame 3 are framed by the fastening members 6 such as nails, wood screws, screws, bolts, and tuckers. Therefore, sufficient strength cannot be ensured, for example, the frame is broken when the process proceeds to the step of attaching the decorative board 4 after the frame is completed. Even in the completed door after the decorative plate 4 is pasted, the frame material 10 is distorted due to insufficient strength of the frame material 10, which causes problems such as hindering the opening and closing of the door.

  An object of the present invention is to provide a door structure having sufficient strength even in the case where a laminated material is used for the horizontal frame material of the door, in view of the problems of the conventional horizontal frame material of the door.

  In order to achieve the above object, in the door structure of the present invention, the horizontal frame is formed of a laminated material, and a reinforcing member that covers the edge of the horizontal frame is provided at the frame frame joint at the edge of the horizontal frame and combined with the reinforcing member. It is characterized in that the collar frame and the horizontal frame are tightened by the fastening member.

  In this case, the reinforcing member can be a member having a U-shaped cross section.

  Moreover, the screw hole for attachment can be provided in the surface of the reinforcement member contact | abutted to a collar frame.

  Moreover, a notch part can be provided in the edge part of a horizontal frame, and a horizontal frame surface and a reinforcement member surface can be made into the same surface.

  According to the door structure of the present invention, the horizontal frame is formed of a laminated material, and the reinforcing member that covers the end of the horizontal frame is provided at the end of the horizontal frame at the end of the horizontal frame. The fastening member combined with the reinforcing member By tightening the frame and the horizontal frame, the laminated frame will not crack even if screws are screwed in when the frame and horizontal frame are joined together. Can be provided.

  Further, by making the reinforcing member a U-shaped cross section, for example, the reinforcing member can be bent from a metal plate, extruded from a metal material, or cut out from a synthetic resin material. Can be easily manufactured.

  Further, by providing a screw hole for attachment on the surface of the reinforcing member that comes into contact with the collar frame, it is possible to sufficiently secure the bonding strength between the collar frame and the horizontal frame.

  In addition, by providing a notch portion at the end of the horizontal frame and making the horizontal frame surface and the reinforcing member surface the same surface, it is possible to eliminate the step at the frame material end, and when attaching a glass window or louver to the door, The attaching operation can be easily performed.

  Hereinafter, embodiments of the door structure of the present invention will be described with reference to the drawings.

This door 1 is composed of two frame frames 2 and 2 and a horizontal frame 3 of an upper frame 3a, a lower frame 3b and an intermediate rail 3c as in the prior art, and when a glass window W is provided in the center. The vertical middle rails 2a and 2a and the horizontal middle rail 3d are provided.

  In the door 1, a reinforcing member 5 that covers these end portions is disposed at the end portions of the horizontal frame 3, and in the present embodiment, at the end portions of the longitudinal middle rails 2 a and 2 a.

As long as the reinforcing member 5 has a structure that can cover the end portions of the horizontal frame 3 and the middle rail 2a, the configuration and the manufacturing method thereof are not particularly limited. For example, the reinforcing member 5 is made of a metal such as steel, stainless steel, or aluminum. It can be easily manufactured by bending a plate material into a U-shaped cross-section, extruding a metal material such as aluminum, and cutting and molding a synthetic resin material.
The material of the reinforcing member 5 is not particularly limited. However, even if a fastening member 6 such as a screw or a tapping screw is screwed into the end of the horizontal frame 3 or the intermediate rail 2a made of a laminated material, the laminated material is used. It is sufficient that the horizontal frame 3 and the middle rail 2a are strong enough to suppress cracking.

A screw hole (female screw hole) 5a for attachment can be provided on the surface of the reinforcing member 5 that contacts the collar frames 2 and 2.
As a result, the fastening member 6 such as a screw attached from the outer surface of the collar frame 2 is screwed into the screw hole 5a.
