Description

  The present invention relates to a simple mechanism and a one-touch lock device having a robust mechanism that enables a movable body to be quickly and easily attached to and detached from a vertical fixed frame body such as a waterproof device with one touch.

As an example of an apparatus that detachably mounts a movable body on a fixed frame body, there is a waterproof device described in Utility Model Document 1.
This waterproof device prevents inundation due to heavy rain or flooding from the entrance of a building (for example, the entrance of a building, a condominium, or the like, or the entrance of an underground passage entrance / exit).
The waterproof device is provided with a fixing frame at the entrance of the building, and the fixing frame includes a receiving groove portion extending in the vertical direction on each of the left and right side walls of the entrance, and a floor receiving portion on the floor surface of the entrance. The movable body comprises a waterproof plate that is detachably supported on both sides by the receiving groove portion and a lower end edge portion of the floor receiving portion to close the inlet.
A waterproof rubber for preventing inundation is attached to the receiving groove portion and the floor receiving portion. The waterproof plate is provided with a lock device that allows the waterproof plate to be removed from the receiving groove portion and the floor receiving portion.

Japanese Patent No. 3458077

The conventional locking device introduced in Patent Document 1 includes an operation lever that can be rotated between a vertical position (that is, unlock position) and a horizontal position (that is, lock position), and a horizontal position from the vertical position of the operation lever. The front and rear direction pressing force that presses the side waterproof rubber against the inner surface of the receiving portion and the downward pressing force that presses the bottom waterproof rubber against the bottom surface of the inlet are simultaneously applied to the waterproof plate by the rotating operation up to Mechanism.
In addition, this locking device directly engages the base end portion (roller) of the operation lever with the engaged surface on the building side, so that the operation lever is rotated 90 degrees and the front-rear direction pressing force is applied to the waterproof plate by the turning operation. And a downward pressing force are simultaneously generated, the operator needs a large operating force at the operating lever to simultaneously receive the front-rear operating resistance and the pressing-down operating resistance of the waterproof board during the rotating operation. For this reason, fine adjustment is extremely difficult, and the work efficiency is inferior. Therefore, promptness at the time of disaster such as floods is questioned.
