Description

[Detailed Description of the Invention] The present invention relates to a handhold attachment device for a sliding door, in which a frame is attached around a core material of a fusuma sliding door, and a handhold is attached to a handhold attachment hole of the core material of a sliding door.

The handholds on conventional sliding doors are fitted and fixed into the handhold mounting holes formed in the core material of the fusuma.

For this reason, the force that acts on the handhold when opening and closing the fusuma by placing your hand on the handhold (sliding door opening/closing force) acts directly on the handhold attachment hole in the fusuma core material, so it can be used for a long time. This causes the inner diameter of the handrail mounting hole to become larger, causing looseness when the handgrip is installed, and when the sliding door is closed with impact, an impact force acts on the handhold mounting hole, causing its inner diameter to increase. This will cause looseness in the installation of the handrail.

The present invention was developed in view of the above circumstances, and its purpose is to enable the force acting on the handhold to be supported by the side end surface of the sliding door core material and the vertical stile, thereby increasing the inner diameter of the handhold mounting hole. It is an object of the present invention to provide a handhold attachment device for a sliding door that prevents the above-mentioned problems.
