A groove wheel, through which the other rope of the gradual descent machine frictionally passes, and a brake device for the groove wheel are attached to the underside of the seat that is suspended and supported by one of the ropes of the gradual descent machine via a support. A slow descent device is disclosed in Japanese Utility Model Application Publication No. 13050/1983.

The brake device described in this publication has a braking operating lever and a releasing operating lever mounted on a support column in a vertical arrangement, so that both operating levers can be operated even if the seat is unstably suspended from a sliding machine. Due to the fine adjustment, both hands must be used to control the brakes, leaving one hand free for rescue and general operations. In order to avoid this, if the brake device, which is constantly activated, is released by the control lever, the brake device is located directly under the seat, and the length of the control lever cannot be increased. Since the displacement becomes small, the support of the seat by the gradual lowering machine becomes unstable, and fine adjustment of the brake release becomes difficult.

The present invention deals with this problem, and has an operation in which the middle part is pivoted to the center of the front end of the seat 1 so as to be rotatable in a vertical plane, and the handle part 2a projects upwardly in front of the seat. A flexible arm 3 made of a leaf spring is protruded and fixed to the lower end of the lever 2, and the tip of the flexible arm 3 is attached to the operating end of the brake release actuation member 4 provided in the brake device, and the tip of the flexible arm 3 is attached to the handle portion. The extension part 2b of the operating lever 2 is provided behind the flexible arm 3 with a gap that allows the brake to be deflected when the brake is released. It is characterized by:

Since the present invention has the above configuration, the operating lever 2
When pressing the handle portion 2a forward to release the brake, the flexible arm 3 made of a leaf spring deforms according to the operating force and presses the actuating member 4 to release the brake. Therefore, the displacement of the handle portion 2a increases in accordance with the deflection of the flexible arm 3, and sudden brake release can be prevented.

破損する恐れはない。 Furthermore, even if the operating force of the operating lever 2 suddenly becomes excessive due to the oscillation of the seat while descending, the back of the flexible arm 3 is supported by the extended portion 2b of the operating lever 2, and will not flex any further. Therefore, there is no risk of the flexible arm being damaged.

According to the present invention, when the brake is partially released or released by the operation lever 2, the displacement of the handle portion 2a increases in accordance with the elastic deflection of the flexible arm 3,
Since sudden brake release does not occur, it is easy to finely adjust the brake regardless of how much the seat is shaking during descent, and even if the operating force of the operating lever suddenly becomes excessive due to the shaking of the seat, etc. As mentioned above, if there is no risk of the flexible arm 3 being damaged and the seat is simply descending slowly, the seated person may operate the control lever with his or her thighs and perform the required work with both hands. This has the effect of making it possible.
