Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a retractable handle that can be attached to a thin hinged door or drawer without any protrusions on its inner or outer surfaces.

[Conventional technology]

Handles are attached to hinged and sliding doors of fittings, furniture, cooking tables, sinks, etc., but recently it has become desirable to have handles that do not protrude from the front of hinged doors or drawers, No., JP-A-56-
There is a disclosure in Publication No. 3773.

[The problem that the idea attempts to solve]

However, although the known retractable handle can make the front side of the door flush with the front side of the door by retracting the handle when the handle is not in use, the retractable mechanism is large, and in the case of a thin door, it protrudes largely to the back side of the door. Therefore, it cannot be applied to a structure in which the door is attached tightly to the main body side.

The purpose of this invention is to allow even a thin door to fit within the thickness of the door.

[Means to solve the problem]

The present invention was made to achieve the above-mentioned object.The shaft tube is fitted into a cylindrical case to prevent it from coming off, and a spring that causes the shaft tube to protrude is housed inside the shaft tube. A grip is provided at the front end of the case, and a seat plate extending in the longitudinal direction is fixed inside the shaft cylinder. A guide link with a spring-loaded pin at the tip is arranged along the center line of the case. A guide groove with an end is cut, a pin for the guide link is inserted, an upward slope and a downward step are made on the bottom of the guide groove, and the depths are made to vary sequentially, and an engaging part for the pin is provided at the front end, and the pin is gripped. When pushed in, the pin enters the engaging part of the guide groove and holds the shaft cylinder in the case, and when this grip is pushed, the pin exits the engaging part and the shaft cylinder is set to protrude.

As a result, in this invention, when the grip is pushed in, the shaft tube is locked in the case and the grip is held in a recessed state, and when the grip is pushed, the grip and the shaft tube protrude, so the grip can be moved in and out with a single touch. Since it is only necessary to make a hole for fitting the case into the hinged door or drawer, the installation work of the grip is extremely simple, there are no protrusions on both the front and back of the door, and it can be applied even to thin doors.
