DETAILED DESCRIPTION OF THE INVENTION The present invention provides artificial gate opening/closing operations, and
To enable rapid closing operation by lowering the gate's own weight, the rotating shaft is linked to the gate that can be raised and lowered.
The present invention relates to a manual operating device for a gate, in which a handle is interlocked by a gear type booster, and a clutch is manually operated for interlocking the handle and a rotating shaft.

Conventionally, in configuring the above-mentioned manual operating device, there is a connection between the handle 31 and the two-position switching type clutch 32.
As shown in FIG. 3A, a booster having a worm gear 33 was provided, or as shown in FIG. If the reduction ratio is set so that the closing operation can be performed easily, the opening operation will take more time than necessary; on the other hand, if the reduction ratio is set so that the opening operation can be performed quickly, the closing operation will take longer than necessary due to the gate 36 load. There were drawbacks that made it difficult.

The characteristic structure of the manual operating device for a gate according to the present invention is that a gear type booster interposed between a rotating shaft linked to a gate that can be raised and lowered and a handle, a closing operation booster having a worm gear, and a flat A state in which a clutch consisting of a booster for opening operation consisting of a gear and intermittently interlocking the handle and the rotating shaft interlocks the rotating shaft in either direction with respect to the booster for closing operation or opening operation; It is a three-position switching type that can be switched to a state in which it is not interlocked with the opening operation, and the opening operation booster has a first part that prevents the booster from rotating together with the rotation of the rotating shaft in the closing direction. The directional clutch and the second one-way clutch that allows relative rotation of the handle in the closing direction with respect to the booster are provided, and the effects thereof are as follows.

In other words, when the gate is lowered by the handle, the rotating shaft is linked to the booster for closing operation by the clutch, and the action of the worm gear prevents the gate from dropping due to its own weight, and the excess gate load is transferred to the handle. This makes it easier to operate the handle without having to hang it. In addition, when raising the gate using the handle, the rotating shaft is linked to the booster for opening by the clutch, and the reduction ratio can be set much smaller and more appropriately than a worm gear. Therefore, the gate can be raised easily and quickly, and the action of the first one-way clutch prevents the gate from falling under its own weight.

As a result, the gate can be raised and lowered using the handle with appropriate operating force and speed, and in any case, the gate can be operated safely without dropping its own weight, improving operability and safety as a whole. We are now able to provide an excellent manual operation device for gates.

For example, it is conceivable to add separate clutches to the closing operation booster and the opening operation booster and switch the operation state by interlocking operation of these clutches, but the clutch configuration On the other hand, according to the present invention, since a predetermined operation state can be changed by a combination of one three-position switching clutch and a second one-way clutch, the clutch and its operating configuration become complicated. A manual operating device for a gate that can be simplified in its operating configuration, superior in terms of manufacturing and cost, and of high practical value has been obtained.
