Description

[Detailed description of the invention] A. Field of industrial application The present invention relates to an improvement of a sliding hinge used for opening and closing doors of furniture, etc. in architecture.

B. Conventional technology In conventional slide hinges, in order to axially mount links and coil springs on arms and cups, it is common to use separate shafts for each, and fix the shaft ends to the arm side wall by caulking. Ta. (Utility Model Application No. 51-120469, Utility Model Application No. 60-41462, etc.).

C. Purpose of the invention: Reduce the number of parts for the shaft core that penetrates both side walls of the arm, reduce the number of caulking processes at the shaft end, and create a space in the middle by dividing the arm shaft of the outer link into two. The objective is to obtain a larger opening angle than before by expanding the movable range of the inner link.

D. Structure of the invention An example of the implementation of this invention will be explained with reference to the diagram. 1 is a cup, 2 is an arm, 3 is a door, and 4 is the furniture body.

The cup 1 and the arm 2 are connected by an outer link 5 and an inner link 6, and an operating end 9 of a coil spring 8 housed in the arm 2 is in elastic contact with an arm-side projecting leg 7 of the outer link 5.

Reference numeral 10 denotes a shaft core, which is made by bending a single steel wire into an L shape, and consists of a long shaft 11, a joint 12, and a short shaft 13.

The shaft center 10 is connected to the arm 2 from the outside of the arm side wall 14.
is inserted into.

That is, the long axis 11 of one shaft core 10 is inserted into the rear hole 15 of the arm side wall 14 to axially support the coil spring 8, and the long axis 111 of the other shaft core 101 is inserted into the lower hole 171 of the opposite side wall 141. The short shafts 13, 131 of both axes 10, 101 are inserted into the tip holes 16, 161 of the arm side wall 14 to mount the protruding leg 7 of the outer link 5, Both short shafts 13, 131
A space 18 is maintained between the ends.

The long axes 11, 111 of the shaft cores 10, 101 span both side walls 14, 141 of the arm 2, and the coil spring 8 is mounted on one long axis 11, and the other long axis 11
1, the inner link 6 is mounted on the shaft.

Further, the short shafts 13, 131 penetrate into the tip holes 16, 161 to support the protruding legs 7 of the outer link 5, and maintain a space 18 between the short shafts 13, 131.

Since the shaft core 10 is made of a continuous, integral steel wire, if the distance between the short shaft 13 and the long shaft 11 is made slightly larger or smaller than the distance between the front hole 16 and the rear hole 15, insertion will be difficult. The attached shaft core 10 is well fixed to the side wall 14 by its own elastic force, and the shaft core 10 will not come off due to the opening/closing movement of the hinge.

This relationship is exactly the same for the other axes 101 as well.

The short shaft 1 that fixes the protruding leg 7 of the outer link 5
Since a space 18 is maintained between 3 and 131, when the door 3 is opened, the protrusion 19 on the back side of the inner link 6 will fit into this space 18, as shown in FIG.
Therefore, compared to a conventional slide hinge whose axis passes through this space 18, a larger opening angle of the door can be obtained.

In this case, a window 22 is provided in the back plate 21 of the outer link 5 in order to prevent the other protrusion 20 of the inner link 6 from colliding with the outer link 5.

Furthermore, the front hole 16 and the rear hole 1 of the arm side wall 14
By making the interval 5 and the interval between the tip hole 16 and the pilot hole 17 equal, both axes 10 and 101 can be made to have exactly the same shape and size, and the number of parts can be reduced.

Note that the long axes 11, 111 of the shaft cores 10, 101 are the rear holes 15, 151 (not shown) or the lower holes 17,
171 may be inserted.

Example An example is shown in the figure.

G. Effect of the invention Since the protrusion 19 of the inner link 6 is inserted between the short axes 13 and 131 of the axes 10 and 101, the opening angle of the door 3 becomes large.

By utilizing the elastic force of the shaft cores 10, 101, there is no need to caulk the ends of the shaft cores 10, 101, and manufacturing costs can be reduced.
