The opening/closing body 20 configured as described above rotates about the hinge 23 as a fulcrum between a fully closed position in which the opening in the frame 10 is substantially fully closed and a fully open position in which the opening is substantially fully opened (Fig. 3).

When the opening/closing body 20 starts the opening operation from the fully closed position (see FIGS. 3(a) and 4(a)), the operation resistance adding device 30 is provided within a predetermined initial operation range. One resistance is applied (see FIG. 4(b)), and this first resistance is weakened when the opening/closing member 20 moves beyond the initial operating range.

Further, the movement resistance adding device 30 uses the resistance when the opening/closing body 20 is rotated from the outside of the initial movement range (see FIG. 5A) to the inside of the initial movement range as a second resistance. A second resistance is made smaller than the first resistance.

Specifically, the motion resistance adding device 30 includes an engaging portion 31 fixed to the opening/closing body 20 and an engaged portion 32 fixed to the frame 10 .

The engaging portion 31 is elastically deformed in contact with the engaged portion 32 when the opening/closing body 20 is in the initial operation range, and is engaged when the opening/closing body 20 moves beyond the initial opening range. away from the part 32;
Here, the "initial operation range" means that the opening/closing body 20 rotates by a predetermined angle α in the opening direction from the fully closed position in which it contacts or approaches the door stop portion 12a, and the engaging portion 31 moves away from the engaged portion 32. This is the range of rotation of the opening/closing body 20 until it is released (see FIGS. 3 and 4).

The engaging portion 31 is a member elongated in the vertical direction. It is integrally provided with an elastic protrusion 31b positioned closer to the door trailing edge than the matching protrusion 32b, and is positioned closer to the upper end of the door trailing edge side of the opening/closing body 20. - 特許庁

The base piece portion 31 a is formed in a flat plate shape along the surface of the opening/closing body 20 .
The elastic projecting portion 31b is formed in the shape of an inclined piece in cross section which protrudes from the base piece portion 31a and gradually separates from the surface of the opening/closing member 20 as it goes toward the door tip side.

The material of the engaging portion 31 is a material capable of elastically bending the elastic protrusion 31b, and can be, for example, a flexible synthetic resin material, a rubber material, a metal material, or the like.
Means for fixing the engaging portion 31 to the opening/closing body 20 may be adhesion, screwing, riveting, fitting, or the like.

The engaged portion 32 is an elongated member that continues in the vertical direction so as to face the engaging portion 31 . The engaged portion 32 includes a fixed portion 32a fixed to an immovable portion of the frame 10 or the like (in the illustrated example, the frame member 11 on the door trailing edge side) and an engaged projection projecting toward the engaging portion 31 side. 32b integrally therewith, and has a substantially laterally L-shaped cross section (see FIGS. 4 and 5).

The space s inside the substantially concave cross-sectional portion surrounded by the inner surfaces of the fixed portion 32a and the engaged projection portion 32b of the engaged portion 32 and the door trailing edge side frame member 11 is , and elastic projections 31b.

The material of the engaged portion 32 may be a hard material such as a hard synthetic resin or metal material. As another example, the engaged portion 32 may be made of an elastically deformable material, like the engaging portion 31 .
Means for fixing the engaged portion 32 to the door tail side frame member 11 may be adhesion, screwing, riveting, fitting, or the like.

Next, the characteristic functions and effects of the fitting device 1 having the above configuration will be described in detail.
When the opening/closing body 20 rotates from the fully closed position (see FIG. 3(a)) to the opening direction within the initial operation range (within the angle α according to FIGS. 3 and 4), the elastic The projecting portion 31b moves in the space s inside the engaged portion 32 (see FIGS. 4A and 4B). During this movement, the opening action resistance of the opening/closing body 20 is relatively small.

When the opening/closing body 20 further rotates in the opening direction, the elastic protrusion 31b abuts against the engaged protrusion 32b and is elastically deformed within the initial operation range. This elastic deformation increases according to the amount of rotation of the opening/closing body 20 in the opening direction. Therefore, the first resistance due to the elastic deformation is applied to the opening/closing body 20 during the opening operation.

When the opening/closing body 20 further rotates in the opening direction, the elastic protrusion 31b climbs over the engaged protrusion 32b and leaves the engaged protrusion 32b (see FIG. 4(c)). Therefore, the resistance of the opening operation of the opening/closing body 20 is reduced.

Further, when the opening/closing member 20 in the open state is closed from the outside of the initial operation range, the resistance of the closing operation is relatively small until the elastic protrusion 31b comes into contact with the engaged protrusion 32b.
During the closing operation of the opening/closing body 20, the elastic protrusion 31b is elastically deformed when it comes into contact with the engaged protrusion 32b. Therefore, this elastic deformation applies a second resistance to the opening/closing body 20 during the closing operation.
This second resistance is smaller than the first resistance because the elastic protrusion 31b is inclined as described above.

When the opening/closing body 20 is further closed, the elastic protrusion 31b climbs over the engaged protrusion 32b and is accommodated in the space s.

Therefore, according to the fitting device 1, in the initial operation range, the first resistance is applied to the opening operation of the opening/closing body 20 to reduce the speed of the opening operation of the opening/closing body 20, and the opening/closing body 20 suddenly moves. You can prevent it from opening. Therefore, for example, when a person is on the opening side of the opening/closing body 20, the person can notice the initial opening operation of the opening/closing body 20 and retreat so as not to touch the opening/closing body 20. Become.

Further, when the opening/closing body 20 is closed, a second resistance smaller than the first resistance can be applied to the opening/closing body 20 immediately before closing. Therefore, the closing operation of the opening/closing body 20 can be performed smoothly, and the impact when the opening/closing body 20 is fully closed can be reduced by the second resistance immediately before closing.
