Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting seat plate for mounting a lever handle, a knob or the like on a door.

[0002]

2. Description of the Related Art Conventionally, as in Japanese Utility Model Publication No. 25895/1990, a plurality of arc-shaped elongated holes are formed in the peripheral portion of the round-seat main body, and the circular-seat main body corresponding to each arc-shaped elongated hole position. It has been proposed to form a fitting convex portion on the outer peripheral surface of each of the above, and engrave an annular engaging groove on the inner peripheral surface of the fitting body portion of the decorative cap portion fitted to the round seat body.

[0003]

In the above conventional example, the angle between the fitting convex portion and the mating contact surface of the round seat body is not described, and the removal of the decorative cap portion from the round seat body is not described. Is not considered. An object of the present invention is to provide a mounting seat plate that can be easily removed when it is necessary to remove the decorative cap without easily removing the decorative cap by opening and closing a door after mounting.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a mounting base plate comprising a pedestal fixed to a door and a cover mounted to the pedestal. A plurality of engaging protrusions protruding from the outer periphery of the cover, and a deformation hole provided inside at least one of the engaging protrusions. The cover has a covering portion protruding from the outer periphery to the back surface side. In the position corresponding to the engaging convex part, the engaging convex part that protrudes inward and engages with the engaging convex part is provided, and the engaging convex part having the deformation hole inside is provided. At least one contact surface with which the engaging projection is engaged and fitted is inclined, and a notch is provided in the covering portion in the vicinity of the inclined engaging projection.

[0005]

When the cover is pushed in after the pedestal is attached to the door, the engaging projection and the engaging projection come into contact with each other, and the engaging projection is deformed by crushing the deformation hole. The parts engage with each other. When removing the cover, insert the tip of a flat-blade screwdriver into the notch and lift it up a little, and the contact surfaces of the engaging projections and locking projections near that area are inclined, Since the engagement is weak, it can be easily removed.

[0006]

EXAMPLE A pedestal 1 is made of synthetic resin and has a shape like an elongated oval, and a circular shaft hole 7 is provided below the center, and mounting holes 8 ... 8 are provided on the upper and lower ends and both sides of the shaft hole 7. It is provided. Further, the upper and lower ends are provided with slightly flat portions, and the engaging protrusions 3 and 4 projecting outward are provided therein, and arc-shaped deformation holes 5 and 6 are bored inside thereof. The engaging contact surface of the engaging projection 3 at the upper end is upright, and the engaging contact surface of the engaging projection 4 at the lower end is inclined.

The cover 2 is made of metal and has a shape similar to that of the pedestal 1 and is slightly larger than that of the pedestal 1. The cover 2 is provided with a covering portion 9 projecting from the outer periphery to the back surface side. Stop projections 10 and 11 are provided. The engaging contact surface of the upper engaging protrusion 10 is upright, and the engaging contact surface of the lower engaging protrusion 11 is inclined. Further, the cover 2 is provided with a shaft hole 12 at a portion corresponding to the shaft hole 7 of the pedestal 1, and a thin notch 13 is provided at the tip of the cover 9 at the lower end. After inserting the tip of the flat-blade screwdriver 14 into the engaging protrusion 4 at the lower end and the engaging protrusion 11, the cover 2 is removed.

[0008]

As described above, according to the present invention, the cover does not easily come off from the pedestal when the door is opened or closed after it is installed, and when it is necessary to remove the cover, it can be easily done with a flat-blade screwdriver or the like. It has the effect of being removable.
