Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door used in a general house or the like in which edge members are arranged as frame members for four circumferences, and more particularly to a structure of a corner portion in which the edge members are joined to each other.

[0002]

2. Description of the Related Art In the structure of a conventional door body, as shown in FIG. 5, a frame body 1A is constructed by using edge members 1 and 1 as upper and lower horizontal members and left and right vertical members. A door panel 2 is provided on both the front and back surfaces of the core material 3, and the edges of the edge materials 1 and 1 are cut at an angle of 45 degrees so that the cut end surfaces are brought into contact with each other. The L-shaped corner metal fitting 6 is provided inside the corner of the edge material 1, and both edge materials 1, 1 are fixed to the corner metal fitting 6 with screws 7 in advance.

[0003]

In the conventional door body, since the edge portions of the edge members are cut and abutted at 45 degrees as described above, the sharp edge portions at the corners are cut. There is a risk that the exposed edge will be exposed and you may be injured by touching the edge of the cut edge. Since it was stopped, there was a drawback that a great deal of labor was required for the framework work by this screwing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art. A frame body is constructed by using edge members as upper and lower horizontal members and left and right vertical members. A door body having a core material inside and a door panel stretched on both front and back surfaces thereof, wherein the edge portions of each of the edge members are cut at an angle of 45 degrees and the cut end surfaces are brought into contact with each other. The peripheral edge of each door panel is inserted into a receiving groove provided in the outer longitudinal direction of each edge member, and the door panel is adhered to each edge member at the corner portion of the edge member. An L-shaped elastic corner cover material is attached, and both sides of the corner cover material are respectively locked to the respective edge materials, and the elasticity of the corner cover material allows the corner portions to be locked on both sides. It is sandwiched between.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the door body of the present invention will be described in detail below with reference to the drawings. 1 is an exploded perspective view of a corner portion of the door body, FIG. 2 is a front view of the assembled state of FIG. 1, FIG. 3 is a sectional view taken along the line AA of FIG. 2, and FIG. 3 is a partially exploded view of FIG. In each of the above figures, the door body of the present invention constitutes the frame body 1A using the edge members 1 and 1 as the upper and lower horizontal members and the left and right vertical members, and has the core member 3 inside the frame member 1A. The door panels 2 and 2 are stretched on both front and back sides of the above. As shown in FIG. 1, each of the edge members 1 and 1 is formed by cutting the end portion at an angle of 45 degrees and abutting the cut end surfaces against each other to form a rectangular frame 1A. The cut end faces of each of the edge members 1 and 1 are formed by applying an adhesive and joining them together. Then, as an example, the core material 3 having a honeycomb structure is housed in the frame body 1A. The above-mentioned edge materials 1 and 1 are
It is molded with an extrusion mold material such as aluminum.

As shown in FIGS. 3 and 4, each of the door panels 2 and 2 described above has a peripheral edge 21, 21 bent inward, and a receiver provided in the outer longitudinal direction of each edge member 1, 1. It is inserted in the groove 11. That is, a thin receiving groove 11 is formed on the outer side surface of each edge member 1, 1 in the longitudinal direction, and the peripheral end edges 21, 21 of the door panels 2, 2 are inserted into the receiving groove 11, respectively. Is inserted. As shown in FIG. 4, an adhesive agent 5 is applied to the outer surface of each of the edge members 1 and 1 and the core member 3 in the frame 1A, and the door panel 2 is attached to each edge member in this state. 1, 1 and the core material 3 are bonded. If necessary, the adhesive can also be made to flow into the receiving groove 11 so that the peripheral edge 21 of the door panel 2 is adhered to further strengthen the joint between the two.

Next, as shown in FIG.
As shown in FIG. 2, the corner cover member 4 having an L shape and elasticity is attached. This corner cover material 4
As shown in FIG. 2, is formed into an L-shape having an angle slightly smaller than 90 degrees, and its elasticity holds the corner portions of the edge members 1 and 1 from the outside. That is,
The corner cover member 4 has its both sides locked to the edge members 1 and 1, respectively, and the elasticity of the corner cover member 4 causes the corner portions to be sandwiched from both locking member sides. It is preferable that the corner cover member 4 is formed of a hard synthetic resin or an ordinary metal plate to further generate elasticity.

The corner cover member 4 is formed by bending a plate member into an L-shape and has a lateral width substantially equal to that of the edge member 1 and step portions 44, 44 on both sides.
And the stepped portions 44, 44 are engaged with the side edges 14 of the edge member 1, the corner cover member 4 covers the abutting end edge portions 15 of the edge members 1, 1. , It is prevented from being exposed to the outside. Further, the step portions 44, 44 are engaged with the side edges 14 of the edging material 1, whereby the corner cover material 4 and the edging material 1 are attached more firmly.

Further, inside each piece of the corner cover member 4, a protrusion-like locking portion 4 is provided at a position equidistant from each corner.
1, 41 are formed, and the locking portions 41, 41 are used as the edge members 1, 1.
The corner cover member 4 is attached to the corners of the edge members 1 and 1 with one touch by inserting and locking into the locking holes 12 and 12 provided in the edge member 1. Since the corner cover member 4 has elasticity and is attached to the corner portion by being locked, the end joints of the edge members 1 and 1 are sandwiched from the outside to assist a firm joint from the outside. . The engagement of the corner cover member 4 with the edge member 1 is not limited to the protrusion and the circular hole,
The claw piece may be locked in the narrow groove, or a plurality of pins may be inserted into a plurality of small holes. The corner cover member 4 is additionally screwed to each of the edge members 1 and 1 with a screw 43. That is, the screws 43 are inserted through the through holes 42, 42 of the corner cover member 4 and screwed into the screw holes 13, 13 of the edge members 1, 1 so that the corner cover member 4 and each of the edge members 1, 1 are connected. The joint is made strong as an auxiliary.

[0010]

As described above, according to the present invention, since the corner cover member is attached to the corner portion where the edge members are in contact with each other as described above,
The sharp edge portion of the edge member abutting portion is covered with the corner cover material, and it is possible to reliably prevent an injury caused by touching this. Moreover, the corner cover material is
Since each edge member is locked and attached, the attachment work can be performed very easily by one-touch operation as compared with screwing. Furthermore, since this corner cover material has elasticity and is locked and attached to the edge material, the corners of the edge material are sandwiched from both locking parts sides by its elasticity, and this corner portion is fixed. It can be clamped more firmly. Further, since the frame body is assembled by the edge member by inserting the peripheral edge of the door panel into the receiving groove provided on the outer side of each edge member, it is extremely difficult to assemble with a screw as in the conventional case. Framework work can be done easily.
