Manual gas of cylinder mechanism to open and close via arm
Although it has a damper mechanism, it lacks uniform manual holding force when opening and closing.
There are difficulties. Also, due to gas leakage, the opening and closing function is attenuated,
Durability problems have also arisen due to replacement of the device mechanism. So
This replaces the gas damper mechanism with the rotating shaft, kayle and spring.
A damper mechanism using it has also been proposed. (Actual development 63-
No. 85798. However, the device becomes complicated, and it is necessary to provide a motion mechanism device in which two contradictory motion mechanisms are adjusted. That is, the opening action of the opening / closing body is lifted by the pulling force of the downward spring, but the lowering of the lifted opening / closing body requires a larger force (kinetic energy) to extend the spring in the opposite direction. There was a mechanical wall in eliminating the technical means of changing the motion mechanism into a limited frame.

均一な力関係を保持する。[Operation] When lifting the opening / closing body by the arm, the pulling force of the primary spring is combined with the lifting force of the secondary spring to rotate the partial gear of the arm support shaft to open the opening / closing body. make it easier. In contrast it requires a reverse greater force to extend it against the pulling force of the lowering action is primary spring arm lowering the closing member, the support arm of the primary spring by the rotation of the partial gear If they are brought close to each other in the axial direction, the tensile load force of the primary spring is absorbed by the support shaft, and the descending force is greatly reduced. However, at the same time, due to the rotation of the partial gear of the support shaft, the tip of the rack meshed with the partial gear moves downward and pushes.
If you push down the spring shaft of the secondary spring equipped with a raising spring,
The upward force of the secondary spring acts in the opposite direction to the rotational force of the arm support shaft attached to the transmission gear, and acts to balance with the descending force of the opening / closing body. Maintain a uniform force relationship.

にカム機構としてもよい。EXAMPLE A damper mechanism for opening and closing a gate m of a parking lot or the like will be illustrated and described as an example. In the drawing, 1
Is a pillar frame of the gate m, 2 is an opening / closing arm of the gate attached to the pillar frame 1, 3 is a fixed shaft attached to the support frame 1 , 13 is an arm
4 is a pivot shaft mounted on the fixed shaft 3, and 4 is attached to the pivot shaft.
It is a partial gear. The partial gear 4 constitutes a transmission mechanism with a rack 8 meshing with the partial gear 4, and is rotated by lifting and lowering the arm 2 by opening and closing the gate. Reference numeral 5 denotes a primary spring stretched through a connecting rod 6 connected to one end of the partial gear 4. The primary spring is a downward tension spring that is stretched vertically between the mounting hole 7 of the support frame and lifts the arm when the gate is opened. A rack 8 meshes with the partial gear 4 and is attached so as to slide up and down following the rotation of the partial gear 4 axially attached to the arm in the direction of the arrow. 9 is a spring shaft around which the secondary spring 12 is wound ,
Posts provided appropriate small gap 10 between the lower end of the rack 8
A mounting bracket 11 fixed to the frame 1 is mounted so as to be movable up and down , and a secondary spring 12 that exerts a compressed upward pushing action is mounted on the spring shaft 9 . The spring shaft 9 is pushed down when the rack is moved downward by the arm descending and is attached to the mounting bracket 11.
The secondary spring 12 is compressed to apply a reverse upward force to the spring shaft 9. It should be noted that the tension spring and the push spring due to the relationship between the primary spring and the secondary spring may be attached so as to act in the opposite manner to the embodiment. The transmission mechanism may be a cam mechanism in addition to the gear mechanism of the embodiment.
