[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an adjusting leg for a device, such as a computer or a copying machine, which is screwed and attached to the bottom of the device and is used to arrange the device at a predetermined height or a reference horizontal position. It is about.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Laid-Open No. 63-15239, in the prior art, a screw rod 53 screwed into a mounting screw portion 52 on the bottom surface of a device 51 and a lower end portion of the screw rod 53. And a hexagonal hole 56 is formed in the lower end surface of the screw rod 53 exposed in the escape recess 55 in the bottom surface of the hexagonal hole 56, and a cross hole 57 is formed in the inner bottom surface of the hexagonal hole 56. It is provided.

When the screwing of the screw rod 53 is adjusted in an inclined position and the device 51 is placed in a horizontal state, the angle of the bottom surface of the seat 54 fixed to the device 51 via the screw rod 53 is on the inclined ground. Since they do not match and the ground contact portion is limited, the equipment 51 is easy to move and unstable especially when installed on a low friction ground.

[0004]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to make the angle of the bottom surface of the seat to match the inclination when the device is installed in a horizontal position on the sloped ground, and the bottom surface is in close contact with the ground. The purpose is to provide an adjustable leg for devices that can do so.

DETAILED DESCRIPTION OF THE INVENTION The reference numerals in the accompanying drawings will be used to explain the adjusting legs of the devices of the present invention.
A screw rod 3 is screwed into a mounting screw portion 2 on the bottom surface of the equipment 1 and a seat plate 4 is fitted to the lower end portion of the screw rod 3, and the screw rod 3 exposed in an escape recess 5 on the bottom surface of the seat plate 4 is mounted. A concave portion 6 is provided on the lower end surface of the, and an inner rotation operating portion 7 is provided on the inner bottom surface of the concave portion.

Further, in the present invention, a hemispherical body portion 8 having an outer rotation operating portion 9 on the upper portion is provided on the outer periphery of the lower end portion of the screw rod 3, and the hemispherical body portion 8 is provided on the upper surface portion of the seat 4. Hemispherical recess 10
The lower end portion 13 of the screw rod 3 provided on the lower surface of the hemispherical body 8 into the escape hole 14 of the seat 4 to prevent the screw rod 3 from being pulled out, and the hemispherical upper surface of the hemispherical recess 10 The hemispherical bottom surface 11 of the hemispherical body 8 is slidably contacted with the screw body 12, and the screw rod 3 is slidably rotated about the center of curvature of the hemispherical upper surface 11.

[0007]

[Operation] When adjusting the height and levelness of the equipment 1,
For example, when the device is lightweight and the required tightening torque is small, a screwdriver or the like is inserted into the inner rotation operation portion 7 to rotate the screw rod 3. When the device is heavy and the required tightening torque is large, the outer rotation operating portion 8 is sandwiched by a spanner or the like to rotate the screw rod 3.

Hemispherical bottom surface 11 of the hemispherical body 8 of the screw rod 3.
Can make a rotary movement on the hemispherical surface 12 of the hemispherical recess 10 of the seat 4 about the center of curvature of the hemispherical bottom surface 11 to change the mounting angle between the screw rod 3 and the seat 4.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, the rubber seat base 4 is a screw rod 3.
Washer is fitted to the lower end of the screw rod 3 and is prevented from moving upward by a hemispherical body that abuts on the outer periphery of the screw rod 3, and a washer is inserted into the upper end of the lowermost end 13 of the screw rod 3 which is widened. The downward movement is blocked by 15.

The lowermost end 13 of the screw rod 3 provided on the lower surface of the hemispherical body 8 is restricted to move within the range of the escape hole 14 of the seat 4, and within this predetermined range, the hemispherical body 8 is a hemisphere. A mortar movement can be performed along the surface recess 9.

The inner rotary operation portion 7 formed into a cross-shaped driver groove is formed concentrically with the shaft center and is exposed at the center of the circular relief recess 5 at the center of the seat 4. Outer rotation operation unit 9
Is processed into a hexagon. The inner rotation operating portion 7 can also be formed in a minus groove. Also, the outer rotation operation unit 9
Can also be formed in other rectangular cross sections.

[0012]

As described above, according to the present invention, the hemispherical body portion 8 of the screw rod 3 slides on the hemispherical surface 12 of the hemispherical recess 10 of the seat 4 around the center of curvature of the hemispherical bottom surface 11. Since it rotates, the mounting angle between the screw rod 3 and the seat 4 can be changed, and the entire bottom surface of the seat 4 is sufficiently inclined to come into contact with the ground.
The equipment 1 can be stably installed in a horizontal position.
