Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting seat plate for mounting a lever handle, knob, etc. on a door.

[0002]

[Prior art]

 Conventionally, as in Japanese Utility Model Publication No. 2-25895, a plurality of arc-shaped elongated holes are formed in the peripheral edge portion of the round seat body and are fitted on the outer peripheral surface of the round seat body corresponding to the respective arc-shaped elongated hole positions. It is proposed that the fitting convex portions are respectively formed and an annular engaging groove is formed on the inner peripheral surface of the fitting body portion of the decorative cap portion that fits into the round seat body.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, the angle between the fitting convex portion and the mating contact surface of the round seat body is not described, and removal of the decorative cap portion from the round seat body is not considered. An object of the present invention is to provide a mounting seat plate which can be easily removed when it is necessary to remove the decorative cap after the installation, because the decorative cap does not easily come off when the door is opened or closed. .

[0004]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION To solve the above problems, the present invention provides a mounting base plate including a base fixed to a door and a cover attached to the base, the base having a plurality of outwardly protruding engagements. The cover is provided with a convex portion and a deformation hole inside at least one engaging convex portion. The cover is provided with a covering portion projecting from the outer periphery to the back surface side, and the engaging convex portion is provided inside the covering portion. The engaging projections that project inward and engage with the engaging projections are provided at the corresponding positions, and the engaging projections that have the deformation holes inside and the corresponding engaging projections. At least one contact surface to be fitted is slanted, and a cutout portion is provided in the covering portion near one slanted locking projection.

[0005]

[Action]

 When the cover is pushed in after the pedestal is attached to the door, the engaging projections and the locking projections come into contact with each other, the engaging projections deform by deforming the deformation holes, and the engaging projections and the locking projections engage. Mating. To remove the cover, insert the tip of a flat-blade screwdriver into the notch and lift it up slightly to tilt the engaging contact surfaces of the engaging projections and locking projections near it. Since the mating engagement is weak, it can be easily removed.

[0006]

【Example】

 The pedestal 1 is made of a synthetic resin and has an elongated oval shape. A circular shaft hole 7 is provided below the center, and mounting holes 8 ... 8 are provided at the upper and lower ends and both sides of the shaft hole 7. 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 protrusion 3 at the upper end is upright, and the engaging contact surface of the engaging protrusion 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 that protrudes from the outer periphery to the back surface side. There are stop projections 10 and 11. 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 cutout portion 13 is provided at a front end portion of the covering portion 9 at a lower end portion. Insert the tip of a flat-blade screwdriver 14 into 13 to disengage the engagement projection 4 and the locking projection 11 at the lower end, and then remove the cover 2.

[0008]

[Effect of device]

 As described above, according to the present invention, after installation, the cover does not easily come off from the pedestal when opening and closing the door, etc., and when it is necessary to remove the cover, it can be easily removed with a minus driver. The effect is that you can do it.
