Locking structure for cover covering handle seat

Abstract

Provided is a locking structure for a cover that covers a handle seat, the locking structure allowing locking and unlocking between the handle seat and the cover by a locking means to be easily implemented, and allowing a locked state therebetween to be surely maintained in order to prevent the cover from coming off. The locking structure for a cover for covering and hiding the front surface and the peripheral surface of a handle seat includes: a cover locking means having a cover side locking part formed at the cover and a handle seat side locking part formed at the handle seat; and a rotation preventing means including a latch, the latch being provided at the position of a groove part that forms the handle seat side locking part and biased to be able to advance / withdraw along an axial line from the center of the handle seat to the outer peripheral surface and toward a tip end thereof, and the latch having, at the tip end, a locking part raised from the bottom of the groove part to protrude in the groove part and abut against the cover side locking part provided to protrude at the cover when the locking means is in a locked state.

Description

technical field [0001] The present invention relates to a locking structure of a cover body covering a disc-shaped handle seat mounted on the inner and outer surfaces of a door for supporting a square core for mounting on the door A handle such as a lever handle or a ball handle is installed on the end of the square core. Background technique [0002] Conventionally, a square core is used to operate a latch installed in a door, and a handle such as a lever handle or a knob is attached to the end of the square core. A disc-shaped handle seat on the surface, which is often fixed to the lock body attached to the door by bolts, etc., these bolts are exposed on the surface, and the hub that holds the square core to which the handle is fixed is also Therefore, after installing it on the door, cover the front and outer peripheral surface by covering the cover to make the outside more beautiful. Especially, recently, the cover and the handle are designed together with the door, etc...

AI Technical Summary

Problems solved by technology

[0005] However, as mentioned above, because it needs to be easily disengaged, the locked state is formed loosely, so that there is a problem that the cover body rotates and the cover body falls off during use. In particular, there is the following problem: the cover covered on the handle base When the body is also a handle lock, if the cover body is easy to rotate due to the operation of the handle, and the handle is rotated, the handle will fall off.
