Field of the Invention The present invention prevents the acceleration when a specific member moves in one direction by braking only the sliding of the rack member in one direction, and quickly achieves the movement in the opposite direction. The present invention relates to a one-way braking device that can be mounted on a relatively heavy lid such as an opening / closing lid of a large copying machine, a back lid of a grand piano, or a front plate of a writing desk.

Description of the Related Art There are many fixtures having an opening / closing lid in the vertical direction in general households and companies, and examples thereof include an A1 size copying machine opening / closing lid, a piano back lid, and a writing desk front plate. . The lids of these fixtures can be pivoted in the vertical direction by hinges and rotating metal fittings, and the hinges are freely pivotable in either the vertical opening or closing direction. You may get injured by pinching your fingers or the product may be damaged by lowering the lid abruptly.

347, JP-A-6-72454, JP-A-7-113.
No. 416 has been proposed and already installed on the lids of various products. These opening / closing restraint devices have an advantage that even if they are attached to a keyboard lid of a piano, etc., the lid body does not suddenly turn downward by appropriately braking in both the upward and downward rotation directions.

ることを要する。The above-mentioned opening / closing suppressing device is popular because it can appropriately adjust the opening / closing operation of the lid, but since it is installed as a rotary shaft of the lid, the lid is attached to the device. The body load will act directly. The opening / closing suppressing device in such an installation mode can suppress the closing operation of a large and heavy lid, even if there is no problem with a relatively light lid such as a display of a laptop computer or a laptop personal computer. It is necessary to use a large one according to the load of the lid.

時の抑制が不十分になりやすい。Further, the opening / closing suppressing device similarly suppresses both the upward opening operation and the downward closing operation of the lid body. Therefore, when the opening / closing suppressing device is adjusted to sufficiently suppress the closing operation of the lid, the opening operation of the lid becomes considerably difficult, while the opening operation of the lid becomes comfortable. If the adjustment is made to 1, the suppression during the closing operation of the lid tends to be insufficient.

An object of the present invention is to provide a small size as compared with a rotating body even when braking a downward swing of a relatively large and heavy rotating body by installing the rotating body such as a lid away from the rotation axis. (EN) Provided is a one-way braking device having excellent durability. Another object of the present invention is to prevent acceleration when rotating in the closing direction and to quickly rotate in the opening direction for an opening / closing lid of a large-sized copying machine, a heavy lid such as a piano back lid, and the like. An object is to provide a closure suppression device.

The roller 30 in the recessed groove 33 bites into the inner wall surface of the groove by the elastic force of the spring 31, and the rotating body is braked and rotated together with the collar 35, that is, the shaft body 14. Therefore, when the rotating body is closed, a sudden downward turn can be braked to quietly close the rotating body.

め、開閉蓋３が重くても破損しない。When the pinion 12 rotates clockwise in FIG. 6 as the rack member 11 travels upward, the rollers 30 in the grooves 33 rotate clockwise, and the rollers 31 rotate in the spring 31.
By moving away from the inner wall surface of the groove against the elasticity of the pinion 12, the pinion 12 idles around the collar 35. Therefore,
It is extremely easy to open the open / close lid 3 upward. Further, when turning downward to close the opening / closing lid 3, the pinion 12 rotates counterclockwise in FIG. 6, and the rollers 30 in the concave grooves 33 are rotated.
Rotate counterclockwise. As a result, each roller 30 bites into the inner wall surface of the groove by the elastic force of the spring 31, and the collar 35
That is, the shaft body 14 can be rotated together with the pinion 12, and the rotation of the shaft body can be suppressed by the braking member 18. Therefore, when the opening / closing lid 3 is closed, a sudden downward turn can be braked and the opening / closing lid 3 can be closed gently. The rotation braking force of the shaft body 14 by the braking member 18 can be easily and delicately adjusted by the screwing amount of the adjusting screw 20 that tightens the holding metal fitting 19, and the closing operation can be easily set according to the user's preference. Further, since the plastic braking member 18 receives the load acting when closing the opening / closing lid 3 with its entire lateral width, it is not damaged even if the opening / closing lid 3 is heavy.
