DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminate hinge used for connecting a door panel to a fixed frame in a cargo truck container or the like.

[0002]

2. Description of the Related Art Laminate hinges are obtained by connecting two aluminum two-wing plates via a bending and stretching plate made of rubber. In a conventional laminate hinge, a wing plate is attached to a door panel made of laminated plywood. At the time of installation, since the screwing of the screw from the end face direction of the door panel has a problem in strength, an L-shaped member is interposed between the wing plate and the door panel, and one of the component plate portions of the L-shaped member is closed. By tightening and fixing to one of the front and rear side surfaces of the panel with screws, overlapping the wing plate on the other component plate part of the L-shaped member, and tightening and fixing to the end surface of the door panel with screws
The required mounting strength is secured.

However, in such a system in which an L-shaped reinforcing member is additionally used separately from the wing plate, the L-shaped member is fixed to the door panel and the wing plate is fixed to the L-shaped member twice. Since work is required, installation work takes time,
The overall cost increases, including the material cost of the L-shaped material.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a laminate hinge which can be cut into a suitable length and easily and firmly attached to an object, and which can reduce costs. is there.

[0005]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. The laminate hinge of the present invention comprises a pair of mounting plates outside the front and rear ends of a base plate portion 1e. A first wing plate 1 made of aluminum having projecting portions 1b and 1c projecting at a right angle and projecting a holding plate portion 1a inside a front end portion of a base plate portion 1e via a receiving groove portion 1d; and a base plate portion 2e. A second wing plate 2 made of aluminum having a holding plate portion 2a protruding inwardly of a front end portion of the first wing plate via a receiving groove portion 2d; and two legs attached to the receiving groove portions 1d and 2d of the first wing plate 1 and the second wing plate 2. It comprises a bending and stretching plate 3 made of rubber into which the plate portions 3a and 3b are inserted.

The base plate portion 1e is moved from the recess 4 of the holding plate portion 1a.
One leg plate portion 3a of the bending and stretching plate 3 is fixed to the base plate portion 1e of the first wing plate 1 by a screw 6 screwed into the fixing blade, and the fixing frame is passed through the base plate portion 2e from the concave portion 5 of the holding plate portion 2a. Body 9
The other leg plate portion 3b of the bending and stretching plate 3 is fixed to the base plate portion 2e of the second wing plate 2, and the base plate portion 1e of the first wing plate 1 is fixed to the door panel. The mounting plates 1b, 1c which abut against the end surface 8a of the door panel 8 and come into contact with the front and rear side surfaces 8b, 8c of the door panel 8 are fixed to the fixing members 14,
15, the base plate portion 2 of the second wing plate 2 is fixed to the door panel 8.
e is abutted against the end surface 9a of the fixed frame 9 and is fixed to the fixed frame 9 by the fixing tool 7 or another fixing tool.

[0007]

This laminate hinge is used by cutting the first wing plate 1, the second wing plate 2, and the bending and stretching plate 3 into appropriate lengths corresponding to the length of the object. Preferably, prior to attaching the first wing plate 1 and the second wing plate 2 to the door panels 8 and 9, the bending and stretching plate 3 is connected to the first wing plate 1 and the second wing plate 2 by the screws 6 and the fixing members 7. It is fixed.

When the door panel 8 is opened and closed by rotating with respect to the fixed frame 9, the bending and stretching plate 3 connecting the first blade 1 and the second blade 2 corresponds to the movement of the door panel 8. Bend and stretch.

[0009]

In the illustrated embodiment, the bending and stretching plate 3 is made of synthetic rubber, the screw 6 for fixing the leg plate portion 3a of the bending and stretching plate 3 to the first wing plate 1 is a tapping screw, and the tip of the screw 6 is protruded. The concave portion 4 to be applied is provided in a groove shape over the entire length of the holding plate portion 1a of the first blade 1. Base plate 1 of first wing plate 1
e is formed thick to ensure a sufficient screw-in length of the screw 6.

As the fixing member 7 for fixing the leg portion 3b of the bending and stretching plate 3 to the second wing plate 2, a tapping screw, a bolt, or the like is used. When the fixing tool 7 is a tapping screw, the concave portion 5 against which the tip of the screw is abutted is provided on the pressing plate 2 of the second blade 2.
a is provided in a groove shape over the entire length of a. When the fixing member 7 is a bolt, a rivet, or the like, the concave portion 5 is formed in a through hole, and a required receiving hole 13 is formed in the leg plate portion 3b and the base plate portion 2e of the bending and stretching plate 3. A fixing tool for fixing the second wing plate 2 to the fixing frame 9 can be prepared separately from the fixing tool 7 for fixing the bending and stretching plate 3 to the second wing plate 2, and the fixing tool is a pressing plate portion 2a. , Leg plate 3b and base plate 2e.

In order to facilitate the insertion of the leg plate 3a of the bending and stretching plate 3 into the receiving groove 1d of the first wing plate 1, the distance between the base plate 1e and the holding plate 1a is increased toward the insertion end. The holding plate 1a is formed to be inclined with respect to the base plate 1e. Insert the leg plate 3a into the receiving groove 1d
When tightening and fixing with
In order to make it easy to bend in parallel with e, a guide line portion 1f is formed on the outer surface of the receiving groove portion 1d over the entire length.

The leg plate portion 3b of the bending and stretching plate 3 is connected to the second wing plate 2
The holding plate 2a is inclined with respect to the base plate 2e so that the distance between the base plate 2e and the holding plate 2a increases toward the insertion side end in order to facilitate insertion into the receiving groove 2d. It is formed. When the leg plate portion 3a is inserted into the receiving groove portion 2d and fastened and fixed with the fixing member 7, the guide line is provided on the outer surface of the receiving groove portion 2d so that the pressing plate portion 2a is easily bent in parallel with the base plate portion 2e. The portion 2f is formed over the entire length.

The through holes 1 in the mounting plate portions 1b, 1c of the first blade 1
The holes 0 and 11 are perforated in advance at the factory stage at predetermined intervals in the length direction of the first blade 1. Also, the through holes 12 in the base plate portion 2e of the second blade 2 are pre-drilled at a factory stage at a constant interval in the length direction of the second blade 2. Screws are used as the fixing tools 14 and 15, but other known fixing means such as bolts and rivets can be used.

[0014]

As described above, in the laminate hinge of the present invention, a pair of mounting plate portions 1b and 1c are provided at right angles outside the front and rear ends of the base plate portion 1e of the first wing plate 1, and Pressing plate 1a is inserted into the inside of the front end of plate 1e via receiving groove 1d.
And a holding plate 2a is protruded inwardly of the front end of the base plate 2e of the second wing plate 2 via a receiving groove 2d, and one leg plate 3a of the bending and stretching plate 3 is provided. The screw 6 is inserted into the receiving groove 1d and the screw 6 is inserted from the concave portion 4 of the holding plate 1a.
And the other leg plate portion 3b of the bending and stretching plate 3 is inserted into the receiving groove portion 2.
d, and the fixing member 7 is screwed into the base plate portion 2e from the concave portion 5 of the holding plate portion 2a, whereby the bending and stretching plate 3 is fixed to the first wing plate 1 and the second wing plate 2, and the first wing plate 3 is placed. The base plate portion 1e of the plate 1 abuts against the end surface 8a of the door panel 8, and the door panel 8
Mounting plate portions 1b, 1c abutted on front and rear side surfaces 8b, 8c
