Description

[Detailed description of the invention] (Field of industrial application) The present invention is designed to be attached to the support leg of a container, more specifically, to the lower end of a container such as a support for various equipment, furniture, etc., and to raise the height of the container. This invention relates to a so-called azimuth star foot bolt whose height and angle are adjustable.

(Prior art and its problems) Conventionally, this type of supporting leg has been designed to allow adjustment of the height of the vessel from the floor and the angle of inclination according to the slopes and unevenness of the floor. There are several known devices in which the vessel body can be placed on the floor with good stability (for example, Utility Model Application No. 1987-95970,
(Refer to Utility Model Publication No. 51-22567, Utility Model Publication No. 101547, 1983, and Utility Model Application Publication No. 60-79090).

However, in conventional support legs, the height is generally adjusted by rotating the bolt as the support leg, but this rotation operation is essentially a nut provided integrally with the support shaft. The only way to do this is to engage a tool with a tool engaging part such as a part, in other words, there is no means to rotate the support shaft to a certain extent without using a tool. , which is extremely inconvenient. Further, even in a support leg having a tiltable structure, there is a problem that the joint between the pedestal and the support shaft that constitute the support leg lacks stability and strength.

(Means for Solving the Problems) To summarize, the present invention for achieving the above object includes a hemispherical convex seat formed on the upper center surface of the pedestal, and a hemispherical convex seat formed on the lower end surface of the screw support shaft. A hemispherical recess is rotatably and tiltably slidably fitted and coupled, and a central portion of the exterior body is integrally fitted and fixed to the outer periphery of the lower end of the screw support shaft, and the exterior body is extended from the center portion to the pedestal. It extends to the outer periphery and is bent downward to form a rotation operation part.

(Function) A plurality of the supporting legs having the above configuration are inserted into a screw hole provided at a required lower end of the vessel body, for example, on the bottom surface, at the tip of the leg from the tip of the screw supporting shaft, and the rotation operation portion is inserted into the screw hole. Attaches by rotating and screwing. With the supporting legs attached in this way, the height from the floor when the vessel is in the standing state with the pedestal in contact with the floor can be determined by rotating the supporting shaft clockwise or counterclockwise using the rotation operation section. It is adjusted by moving it up and down. In addition, in the above-mentioned stationary state, there are slopes and uneven parts on the floor surface,
When the pedestal is located in these areas, the pedestal is tilted around the protruding seat portion depending on the state of these areas, and is fixed to these areas with good stability.

(Example) The present invention will be further explained based on the illustrated example as follows.

As shown in FIGS. 1 and 2, it includes a pedestal 1, a support plate 2, a screw support shaft 3, and an exterior body 4. The pedestal 1 is made of synthetic resin, and the outer diameter of its lower half is smaller than the outer diameter of its upper half,
Its surface is flocked and a through hole 5 is formed in its center. The support board 2 is made of metal, has a hemispherical convex seat part 6 in the center, and a through hole 7 at the top of the seat part, and is fixed integrally to the upper surface of the base 1 with an adhesive. It has been done. The screw support shaft 3 is made of metal, has a screw 8 on its outer surface except for its lower end, and is slidably fitted to the lower end surface of the support shaft in a vertical state so as to be rotatable and tiltable with approximately the upper half of the seat portion 6. A hemispherical recess 9 is formed. The exterior body 4 is made of synthetic resin and includes a cylindrical portion 10 whose upper half is a tool engaging portion 10a.
and a rotating operation part (handle) 11 extending from the axial middle of the cylindrical part to the outer periphery and bending downward, and the cylindrical part 10 is integrally fitted and fixed to the lower end outer periphery of the support shaft 3. There is. The outer periphery of the rotating operation portion 11 is formed into an uneven surface 11a to prevent the operator's hand from slipping and to facilitate the operation.

The support leg is constructed by fitting the concave part 9 of the support shaft 3 into the protruding seat part 6 of the support plate 2, and inserting a washer 12 into the lower surface of the through hole 7 of the seat part.
are brought into contact with each other, a screw 13 is inserted through the through hole 5 of the base 1, and the screw is screwed in the axial direction of the screw support shaft 3 through the washer 12. In this way, when the respective members are connected, the exterior body 4 covers almost the upper half of the base 1.

The supporting leg configured in this manner is attached to a predetermined vessel by screwing into a screw hole (not shown) provided at the lower end of the vessel. This screw-in operation can be performed by rotating the rotation operation part 11 by hand to raise and lower the screw support shaft 3, but the screw is rotated and tightened to the extent that it is difficult to perform rotation operation by hand. In this case, a tool can be engaged with the tool engaging portion 10a and rotated. The height of the vessel from the floor can be adjusted by rotating the rotating operation section 11 or the tool engaging section 10a clockwise or counterclockwise, as described above. . In addition, in the pedestal 1, the concave portion 9 at the lower end of the screw support shaft 3 is rotatably and tiltably coupled to the protruding seat portion 6 of the support plate 2 via a washer 12 and a screw 13, that is, articulated. This allows it to automatically tilt in response to uneven floors and slopes. Furthermore, as is clear from this tilting function, the screw 13
The size of the through hole 7 in which the is located is set to allow this tilting movement over a predetermined angle.

(Effects of the invention) The present invention, which has the above-mentioned configuration, can adjust the height of the vessel from the floor via its support legs, and when the floor has a sloped part, etc. Similar to known techniques, it is possible to automatically take a required angle depending on the slope.

However, in the present invention, the rotation operation part that is integrally fitted and fixed to the screw support shaft covers the upper half of the pedestal including the joint between the support shaft and the pedestal.
Since the external appearance is very good and it is formed in a size that reaches the outer periphery of the pedestal, the rotation operation of the support shaft can be easily performed by rotating the rotation operation part by hand. I can do it.

Furthermore, the joint between the screw support shaft and the pedestal is achieved by connecting a convex protrusion formed at the center of the upper surface of the pedestal and a recess formed at the lower end of the support shaft, which is slidably fitted into the protrusion so as to be rotatable and tiltable. It has high stability and strength.

In addition, the hemispherical convex seat part that tiltably slides into the hemispherical concave part on the lower end surface of the screw support shaft means that when the support shaft is in a vertical state, the concave part is approximately in the upper half of the seat part. At the same time, since the outer diameter of approximately the lower half of the pedestal covered by the rotation operation part is smaller than the outer diameter of approximately the upper half of the pedestal, the screw support shaft of the supporting leg The angle range can be increased.
