Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a hinge that is attached to a door and a fixed body of a building or furniture. This relates to a wing hinge.

[Prior Art] Generally, when attaching a door to a frame, one wing board having a shaft pin is fixed to the frame, and the door with the other wing board fixed is inserted through the shaft pin. When fixing, the frame and the door are positioned in advance, but the height may need to be adjusted after installation.

In view of the need for such height adjustment, the present applicant has provided female threads at both ends of the tube of the vane hinge and a male thread on the prosthetic star, as shown in Utility Application No. 57-92977. The height is adjusted by screwing into the female threads at both ends and adjusting the feed amount.

[Problems to be solved by the invention] According to this method, it is necessary to cut internal threads inside each end of the pipe, which inevitably increases the price. Also, consideration must be given to loosening of the screw feeding part due to rotation of the prosthetic star during use. That is, a fixing mechanism was required to prevent loosening.

Although the heights of the slats can be adjusted with the above conventional technology, this invention makes the height adjustment mechanism of the slats separate from the slats, which eliminates the need for processing the slats, making it simple, The purpose is to provide a reliable and inexpensive height adjustment means.

[Means for Solving the Problems] This invention is characterized in that the ring is divided into male and female ring members whose height dimensions can be selected depending on each fitting position.

That is, the ring includes a male ring member consisting of a disc part and a plurality of leg parts of the same height that protrude in the axial direction from the disc part, and one end surface of the cylindrical shape corresponding to the position of the plurality of leg parts. It consists of a female ring member having a plurality of sets of fitting grooves of the same depth dimension and a plurality of sets of fitting grooves of different depth dimensions, and the depth dimension of the fitting grooves can be selected to differentiate between male and female. It has a configuration in which a ring member is fitted.

[Function] When adjusting, lift the blade plate fixed to the door etc. upward to open the space between the tubes, and then insert the legs of the male ring member from the set of fitting grooves of the female ring member inserted into the shaft pin. part. Next, by inserting the legs into the set of fitting grooves with the desired shallow depth, the disk portion will protrude by the shallow depth and the vertical height dimension will be set, so the height dimension of the slats of doors etc. be adjusted.

[Example] The hinge according to this invention has two slats 1, 2 and 1.
It consists of axle pins 3 and a set of rings 4. The two blade plates 1 and 2 have the same shape, and each has a plurality of screw holes 5. A tube 6 is provided at one end of each of the vanes 1 and 2 by curling or the like. The shaft pin 3 is inserted into a tube 6 of one of the vanes 1 and fixed thereto. In the figure, 7 is a prosthetic star fixed to the upper and lower ends of the tube 6.

Thus, the ring 4 is divided into male and female ring members 8 and 9. As the ring 4, a wear-resistant or slip-resistant synthetic resin can be selected. The male ring member 8 consists of a disc part 10 and a plurality of leg parts 11 provided at the same height in the axial direction as shown in the figure below the disc part 10. Each leg 11 has a rod shape with a flat tip, and is provided so that a line connecting the ends of each leg 11 forms a square.
The disk portion 10 has a wall thickness that does not deform, and the center portion thereof is a hollow hole portion through which the shaft pin 3 is inserted. Therefore, the depth of the leg portion 11 must also be of a size that does not hinder the insertion of the shaft pin 3.

On the other hand, the female ring member 9 has a relatively short cylindrical shape, and is fitted with a leg portion 11 of the male ring member 8 downward (in the axial direction) from the upper surface, which is one end surface of the cylinder. Grooves 12, 13, 14 are provided. These grooves consist of a deepest fitting groove 12, a medium-deep fitting groove 13, and a shallowest fitting groove 14, each of which has a set corresponding to the number of legs 11 provided at its corresponding position. . Each fitting groove 12, 13, 14
Assuming that the depth of the deepest fitting groove 12 is h1, the depth of the medium-deep fitting groove 13 is h2, and the depth of the shallowest fitting groove 14 is h3, h1, h2, and h3 are respectively Set to any dimensions necessary for adjustment. For example, each 3
mm, 2 mm, and 1 mm. A support surface 15 is formed on the upper surface of the female ring member 9. Further, the length of the leg portion 11 of the male ring member 8 is the length of the deepest fitting groove 1.
It is better to have the same depth as h1 of 2.

To explain the operation based on the above configuration, the shaft pin 3
The blade plate 1 integrated with the is attached to the fixed body A with the shaft pin 3 facing upward, and then the ring 4 with the male ring member 8 fitted to the female ring member 9 is attached to the shaft pin 3.
Insert into. At this time, the leg portion 11 of the male ring member 8
is fitted into the deepest fitting groove 12 of the female ring member 9. That is, the vertical width of the ring 4 is at its shortest. Furthermore, the other wing plate 2 fixed to the door B is inserted from above the ring 4.

As a result, as shown in FIG. 5, when the upper end of the door B is lower than the upper end of the fixed body A, it is necessary to raise the vane plate 2 in order to align both upper ends. Therefore, the blade plate 2 and the ring 4 are removed from the shaft pin 3, and the leg portion 11 of the male ring member 8 is attached to the female ring member 9.
When the blades 2 and the door are moved and fitted from the deepest fitting groove 12 to the middle deep fitting groove 13, the blade 2 and the door rise by the difference between h1 and h2. If you want to raise the blade board 2 further, by fitting the leg part 11 into the shallowest fitting groove 14,
And door B is further raised by the difference between h2 and h3.

[Effects] This invention having the above-described configuration and operation has the following effects.

Since the height of the hinge is adjusted by a ring that is separate from the slats, it can be used with all hinges that have a shaft pin into which the ring can be fitted, and can be used with hinges without height adjustment. A height adjustment mechanism can be added.

Due to the ring fitting structure, the fitting position will not come off and can withstand use over time.

Adjusting the height of the vane plate does not require a conventional screw feeding mechanism and a locking mechanism for preventing loosening of the screws, so the structure can be simplified and costs can be reduced.

The fitting structure of the fitting groove and the leg allows
The male and female fittings can be easily removed without removing the upper tube from the shaft pin while the door is lifted. In addition, by simply fitting the legs into adjacent fitting grooves at different depth positions, the height can be adjusted extremely easily, and at the same time, the position can be selected reliably.
