Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pull tab attached to sliding doors and doors such as fittings and furniture.

[0002]

2. Description of the Related Art A pull tab 90 conventionally attached to a sliding door or the like.
As shown in FIG. 7, a casing 91 is provided with a casing 91 having a finger-holding concave portion 92 on its surface, and a flange portion 93 projecting outwardly around the surface thereof.

When attaching the pull tab 90, a digging hole 95 is formed in the sliding door 94, a casing 91 is embedded in the digging hole 95, and the digging hole is formed from the upper wall 96 and the lower wall 97 of the finger hooking recess 92. Nail 98 was driven into the side wall of 95 and fixed.

By the way, when the nail 98 is vertically driven and attached to the upper wall 96 and the lower wall 97, the hammering stroke of the hammer is restricted by the vertical dimension of the finger hook recess 92. For this reason, it was impossible to apply force to the driving. In particular, the launching operation from the lower side toward the upper wall 96 is extremely troublesome, and in any case, the assembling operation takes time and effort.

Further, during the driving operation, the nail 98 tends to be driven obliquely from the front side away from the finger hook recess 92, and when the driving is performed obliquely, the head of the nail 98 comes from the upper wall 96 and the lower wall 97. There was an unavoidable risk of diagonal exposure. If the head of the nail 98 is slightly obliquely exposed, there is a possibility that the nail will touch the fingertip of the user.

Further, when the sliding door 94 is continuously used, the nail 98 is moved to the upper wall 9 due to the repeated impact with the pillar or the like when opening and closing.
6 and the lower wall 97 may come out early. As a result, not only the user's fingertip but also the pull tab 90 may fall off.

A screw may be used instead of the nail 98, but when screwing in, the screwdriver is restricted by the finger-holding recess 92 and is used diagonally, which is still a troublesome work. It was In addition, oblique exposure and embossment were inevitable as in the description.

On the other hand, if the pull tab 90 is attached by the nail 98, it is necessary to pull out the nail 98 at the time of removal, which is troublesome as in the driving operation, and the pull tab 90 and the sliding door 94 are damaged during the pulling operation. There is a concern that it will be turned on.

The present invention has been made in view of such circumstances, and provides a puller which is easily attached to the digging hole with one touch to enhance safety and can be easily removed. The purpose is to do.
