Abstract

PURPOSE:To obtain the device capable of lightly and suitably performing threaded engagement and rotation as it is easy to produce and painting is easily performed. CONSTITUTION:The device comprises a landing body 1 forming an upward and downward through hole 6 and a connection body 10 having an upper large-diameter cylindrical part 11 and lower small-diameter cylindrical part 12, after the small-diameter cylindrical part 12 is inserted in a through hole 6 from upward, with the lower end thereof calked in the direction of a wide diameter, the connection body 10 is fixably formed on the landing body 1 and a center hole part is made in a connection part 15. Because the connection body 10 can be calked after the landing body 1 is painted, the connection body 10 alone can be plated and the connection for the other structure can be easily performed with rivets and bolts and nuts through a hole-like connection part without any influence of paint. The landing body 1 is sandwiched between a wide-diameter direction calked small-diameter part 12 and a large-diameter cylindrical part 11, so the connection body 10 can be firmly connected to the landing body 1 without any need of welding. On the connection body 10 a screw hole is not crushed and threaded engagement and rotation can be performed lightly and suitably without any deformation caused by welding distortion.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg device which can be attached to various structures such as lower ends of columns of a frame shelf or a lower portion of a large storage case.

[0002]

2. Description of the Related Art Heretofore, as a leg device of this type, a structure disclosed in, for example, Japanese Patent Laid-Open No. 2-33013 has been provided. In this conventional configuration, a detachable seating member is attached to the lower end of the column, a base plate, side plates and front plates that stand upright on the base plate by welding and contact the outer surface of the column, and by welding to the lower surface of the base plate. It is composed of a fixed nut member. An adjusting tool for level adjustment is composed of a fixed plate and a bolt member rotatably erected on the fixed plate and screwed to the nut member.

According to this conventional structure, with the fixing plate fixed to the floor surface, the bolt member is screwed onto the nut member to connect the seating member to the adjusting tool, and the seating member is connected to the lower end portion of the column. It is used by concatenating. Then, the bolt member is rotated through a nut attached to the bolt member, and the relative position of the bolt member and the nut member is displaced in the vertical direction, thereby adjusting the level of the column with respect to the floor surface.

[0004]

However, in the above-mentioned conventional structure, since the adjusting member has the bolt member rotatably erected on the fixed plate, it is complicated to perform stable rotation support. Therefore, a highly accurate support structure is required, which cannot be easily manufactured and is expensive. It is also proposed to fix the nut member on the fixing plate by welding in order to perform rotation support, but in this case, the fixing plate and the nut member are easily deformed due to welding distortion, and the bolt member rotates. It will be difficult. Further, since the coating process is started after welding, the paint adheres to the screw holes of the nut member, which makes it difficult for the bolt member to rotate.

An object of the present invention is to provide a leg device which is easy to manufacture and can be coated easily, and can be suitably screwed and rotated.

[0006]

In order to achieve the above object, a leg device according to the first aspect of the present invention has a landing body having vertical through holes, a large diameter large cylindrical portion and a small diameter small cylindrical portion. This connecting body is formed so that the small diameter cylindrical portion is inserted into the through hole from above and then the lower end is caulked in the radial expansion direction so as to be fixed to the landing body, and the central hole portion is connected. Formed on the part.

The leg device according to the second aspect of the present invention has a landing body having through holes formed in the vertical direction, a connecting body having an upper large diameter tubular portion and a lower diameter small tubular portion, and is freely screwable to the connecting body. The connecting body is formed by inserting the small diameter tubular portion into the through hole from above and then caulking the lower end in the radial direction to be fixed to the landing body, and the central hole portion of the connecting body. The connecting rod is formed in a screw hole, and the connecting rod has an operating portion formed in the middle thereof, and a screw portion which can be screwed into the screw hole is formed below the operating portion.

In the leg device of the third aspect of the invention, the landing body having through holes formed in the vertical direction, the connecting body having the upper large diameter tubular portion and the lower diameter small tubular portion, and screwable to the connecting body The connecting body is formed by inserting the small diameter tubular portion into the through hole from above and then caulking the lower end in the radial direction to be fixed to the landing body, and the central hole portion of the connecting body. The connecting rod is formed in a screw hole, the operating portion is formed in the middle, and screw portions in opposite directions are formed on the upper and lower sides of the operating portion, and the lower screw portion is configured to be screwed into the screw hole. ing.

[0009]

According to the structure of the first aspect of the present invention, since the connecting body can be caulked after the landing body is painted, only the connecting body can be plated. The connecting body can firmly connect to the landing body without welding by sandwiching the landing body by the small diameter tubular portion and the large diameter tubular portion crimped in the radial direction. The connection with another structure can be easily performed through a hole-shaped connection portion through rivets or bolts and nuts.

According to the structure of the second aspect of the present invention, the connection with another structure is performed by rotating the connecting rod through the operating portion to screw the screw portion into the screw hole, and then connecting the connecting rod. This can be done by connecting the upper part of the to the structure, and the level of the structure with respect to the floor can be adjusted by rotating the operation part.

Further, according to the structure of the third aspect of the present invention, connection with another structure can be performed by screwing the upper screw portion of the connecting rod into the screw hole on the structure side, and the level adjustment is performed by the operation portion. It can be done by rotating through.
