Problems solved by technology

However, in the existing hinge device with a buffer, since the buffering effect of suppressing the rotation speed of the door and window to a low speed is constant, there is a problem that the rotation speed of the door and window cannot be rotated at a low speed and each user's preference. matching question

Embodiment Construction

[0061] The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

[0062] Figure 1 to Figure 29 A first embodiment of the hinge device with a bumper according to the present invention is given. The hinge device 1 with a buffer of the present embodiment is as Figure 1 to Figure 8 As shown, the main structural elements include: base 2, hinge main body (frame side mounting part) 3, inner link (first link) 4, outer link (second link) 5, cup (door and window sash) side mounts) 6, torsion coil spring 7 and swivel buffer 8.

[0063] The base 2 is for detachably attaching the hinge main body 3 to the inner surface of the side wall of a front-opened frame (not shown), and has a base piece 21 and a movable piece 22 . The substrate 21 is attached to the front end portion of the inner surface of the left side wall of the housing, that is, the end portion on the opening side. The substrate 21 can also be installed on the...

Abstract

A rotary damper (8) is disposed between the side plate sections (41, 42) of the inner link (4) of a hinge device. The damper body (81) of the rotary damper (8) is adapted to be movable relative to the rotor (82) in the direction of the rotation axis of the rotor (82). A rotating cam plate (95) and a movable cam plate (96) are provided between the side plate section (42) and the damper body (81). The rotating cam plate (95) moves, depending on the rotational position thereof, the movable cam plate (96) in the direction of the rotation axis of the rotor (82), thereby moving the damper body (81) in the same direction. Then, the size of the gap (S1) formed between the bottom surface of the damper body (81) and the left end surface of the rotor (82) changes. This causes the resistance of the gap (S1) to the flow of fluid flowing through the gap (S1) to change, and as a result, the rotational speed of the rotor (82) when the rotor (82) rotates at low speed is adjusted.

Description

technical field [0001] The present invention relates to a rotary damper and a hinge with damper using the same. Background technique [0002] As described in Patent Document 1 below, a hinge device with a bumper generally has a frame body side mount attached to a frame and a door sash side mount attached to a door sash. The door and window sash side mounting part is rotatably coupled to the frame body side mounting part through the first and second connecting rods. Therefore, when the frame body side mounting part is installed on the frame body, and the door and window leaf side mounting part is mounted on the door and window leaf, the door and window leaf is rotatably supported on the frame body through the hinge device. [0003] The hinge device also includes a rotary damper. The rotary damper suppresses the rotational speed of the first link to a low speed, thereby suppressing the rotational speed of the door sash side attachment and the sash to a low speed. [0004] E...
