Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to hinges for doors and the like.

(Conventional technology) Conventionally, when attaching a door to a post etc. with a hinge,
The two mounting plates that make up the hinge are positioned and attached to the door and pillar with screws, and the rotating shaft is inserted into both mounting plates.

(Problems to be Solved by the Invention) However, the above-mentioned conventional device has the disadvantage that it requires positioning of the mounting plate and screwing, making assembly troublesome, and that the screws and the like tend to loosen.

(Purpose of the invention) The present invention aims to eliminate the above-mentioned drawbacks and provide a hinge for doors, etc., which is easy to assemble and is difficult to loosen.

(Structure of the invention) In order to achieve the above-mentioned object, the hinge of the invention has an opening groove that opens on the outer surface and communicates with this groove over the entire length of the edge of the opposite side, and has a width larger than the inner width of the groove. a frame body formed in the longitudinal direction with a retaining groove having an inner width; a cylindrical portion rotatably abutting the end face of the opening groove and having a through hole; and a cylindrical portion having the same shape as the groove and the retaining groove; , the same structure formed by alternately combining a connecting member integrally formed with an engaging portion that is inserted and fitted into these grooves, and a connecting member that has an engaging portion fitted into both the grooves of the pair of frames. It consists of a support shaft that is inserted into a through hole of the shaft center, and the angle of the step formed between the side surface of the opening groove and the slip-out prevention groove is 90° or less.

(Example) The hinge according to the present invention includes frames 1A, 1B, a connecting member 8, and a support shaft 12.

The frames 1A, 1B are made of extruded aluminum, for example, and have thick side edges 2, and have a predetermined width that opens diagonally outward. An opening groove 3 and a substantially semicircular retaining groove 4 communicating with the groove 3 and having an inner width larger than the inner width of the groove 3 are provided over the entire length. Further, the opening groove portion 3
The end face of the opening edge 2 is a circular arc surface 7 that forms the same circle when the frames 1A and 1B are connected, and there is a gap between the side surface of the retaining groove 4 and the opening groove 3. The angle of the step portion 5 formed is 90°. Note that this angle only needs to be 90° or less.

As shown in FIG. 4, the connecting member 8 is made of extruded aluminum material, for example, and has a cross section having the same arcuate surface as the aforementioned arcuate surface, and is a cylindrical portion having a through hole 10 for inserting a support shaft in the center. 9 and an engaging portion 11 integrally molded therewith and having the same shape as the opening groove portion 3 and the retaining groove portion 4.

Next, a method for assembling the frames 1A and 1B will be explained.

First, the connecting member 8 is attached to the frames 1A and 1B. That is, the engaging parts 11 are inserted into the respective grooves 3 and 4 of the frames 1A and 1B. For example, in the case of the one shown in FIG. The connecting member 8a is fixed to the frame 1A by attaching the screw 13 through the cut groove 6. Then, the support shaft 12 is inserted and fixed into the through hole 10 of the connecting member 8a by appropriate means, and a spacer 14 made of synthetic resin is inserted into the protrusion of the support shaft 12, and the second Insert the through hole 10 of the connecting member 8b, and attach the second connecting member 8b to the frame 1 using the screw 13.
It sticks to B. Hereinafter, the connecting member 8 and the support shaft 1 will be explained in order.
By attaching 2, the frames 1A and 1B are connected to each other so as to be openable and closable.

In the embodiment, a plurality of support shafts 12 are used as the support shafts.
However, the frames 1A and 1B may be connected with one support shaft 12 so as to be openable and closable. Note that the spacer 14
is not necessarily necessary.

(Effects of the invention) As is clear from the above explanation, the hinge for doors, etc. according to the invention is installed by inserting a connecting member into two frames, and is supported in the through hole of the connecting member. Since the shaft is inserted and integrated, there is no need to position the hinge as in the conventional case, and since screws are not used, there is no possibility of screw loosening, and assembly is easy. Moreover, a pulling action occurs on the connecting member when opening and closing doors, etc.
Since the angle of the step formed between the side surface of the retaining groove and the opening groove is 90° or less, no groove opening force is applied to the opening groove, and the connecting member does not loosen.

In addition, as shown in the example, if the end surface where the opening groove is located is an arcuate surface and the cylindrical surface of the connecting member is located on this surface, it is possible to prevent a gap from occurring between the frames. .
