Abstract

PROBLEM TO BE SOLVED: To mount this seat board, and to obtain the state of firm installation after mounting. SOLUTION: One pedestal 1 is made of a synthetic resin and manufactured in a discoidal shape, a circular shaft hole 7 is formed at a center, and cylindrical outer leg bodies 6, 6 are disposed in upright on both left and right sides of the shaft hole 7 in a rear. The other pedestal 2 is made of the synthetic resin similarly and manufactured in the discoidal shape, the circular shaft hole 10 is formed at a center, and cylindrical inner leg bodies 8, 8 are disposed in upright on both left and right sides of the shaft hole 10 in a rear. Inward projected projecting sections are formed to internal surfaces at the front end sections of the inner leg bodies 8, 8. The inner leg bodies 8, 8 have outside diameters, in which the inner leg bodies can be inserted into the outer leg bodies 6, 6. Covers 3, 4 are made of a metal and formed in the same discoidal shape as the pedestals 1, 2, and shaft holes 11 are formed at centers. Pins 5, 5 are made of the metal and have diameters slightly smaller than the inside diameters of the inner leg bodies 8 and the diameters slightly larger than the inside diameters of the projecting 9 sections.

Description

Detailed Description of the Invention

[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, the invention of Japanese Patent Laid-Open No. 56-100975 has been proposed as a mounting seat plate to be attached to a door by sandwiching it between a pair of pedestals. In this invention, an outer leg body and an inner leg body are respectively erected on the back surfaces of a pair of pedestals, the inner leg body is inserted into the outer leg body, and a screw is screwed into the inner leg body to be attached. .

[0003]

In the above-mentioned conventional example, the screw is immediately screwed onto the inner surface of the inner leg, and the inner leg is deformed outward from the beginning so that the outer surface of the inner leg is the outer leg. Since it will be pressed against the inner surface, it will take a lot of force from the beginning to the end to screw the screw in, it will take a lot of time and work, and if the outer diameter of the screw is reduced,
Although it does not require a large force, there is a problem in that the pressure contact force becomes weak and a firm mounting state cannot be obtained. Further, there is a problem that the cost of the screw is high and that the inner surface of the inner leg body is easily broken because the screw groove is engraved by the screw, and it is necessary to make it thicker or to provide a slit groove.

[0004]

In order to solve the above problems, the present invention provides a mounting base plate which is mounted on a door by being sandwiched by a pair of pedestals, and a cylindrical outer leg is provided on the back surface of one pedestal. While standing upright, a cylindrical inner leg that is inserted into the outer leg is erected on the back surface of the other pedestal, and the inner surface of the tip of the inner leg has a protrusion that projects inward. Is provided, the pin is inserted into the inner leg, and the pin is brought into contact with the projection to deform the inner leg outwardly so as to be pressed against and attached to the inner surface of the outer leg.

[0005]

[Function] When the inner leg is inserted into the outer leg, and the pin is inserted from the inner leg, it is smooth at first, but it becomes tight from the point where it reaches the protrusion, and the pin head is driven. As a result, the inner leg body is deformed outward, and is attached by pressure contact with the inner surface of the outer leg body.

[0006]

[Embodiment] One pedestal 1 is made of a synthetic resin in a disk shape, a circular shaft hole 7 is provided at the center, and cylindrical outer legs 6, 6 are provided on the left and right sides of the shaft hole 7 on the back surface. It is standing. The other pedestal 2 is also made of a synthetic resin in the shape of a disk, and has a circular shaft hole 10 in the center, and cylindrical inner legs 8 are provided on the back surface on both left and right sides of the shaft hole 10. There is. And the inner leg 8
On the inner surface of the tip portion of 8, the protrusion 9 that protrudes inward is formed.
9 are provided. This inner leg body 8 has an outer diameter that can be inserted into the outer leg body 6.

The covers 3 and 4 are made of metal and have the same disk shape as the pedestals 1 and 2, and have shaft holes 11 and 12 in the center. Pin 5
Numeral 5 is made of metal and has a diameter slightly smaller than the inner diameter of the inner leg body 8 and slightly larger than the inner diameter of the protruding portion 9.

The outer legs 6.6 of the pedestal 1 are inserted into the inner legs 8.8 of the pedestal 2 so that the door 13 is sandwiched therebetween, and the pins 5 and 5 are inserted.
Is inserted into the inner cylinder of the inner leg body 8 of the pedestal 2, and when the pin 5 reaches the location of the protrusion 9, it is hammered in to deform the portion of the protrusion 9 9 outwardly, The outer surface of the inner leg body 8.8 is brought into pressure contact with the inner surface of the outer leg body 6.6 to attach the pedestal 1.2 to the door 1.
Attach to 3. After that, the covers 3 and 4 may be attached to the bases 1 and 2, respectively.

[0009]

As described above, according to the present invention, when the pin is inserted, the pin can be easily inserted until it reaches the protrusion, and the inner leg body is tightened from the position where it reaches the protrusion and the head of the pin is driven. Since it can be deformed outward and pressed against the outer leg to be attached, it is inexpensive without using screws and can be easily and quickly attached without the need for tools such as a screwdriver. After that, there is an effect that a firm mounting state can be obtained.
