Title:
TOP PLATE CONNECTING DEVICE
Document Type and Number:
Japanese Patent JP2705489
Kind Code:
B2
Abstract:

PURPOSE: To simplify the constitution of a top plate connecting device by adjusting the height of a top plate by means of the rotation of a seat by butting a bolt with the non-circular seat or the seat of a nut against the retreat piece of a metal fitting.
CONSTITUTION: The bolt 20 is a bolt with a seat 54, and the seat 54 has an oval, non-circular shape, and the outer perimeter of the seat 54 is made to be buttable against a retreat piece 30R. The inner diameters of openings 38, 46 are made to be the ones through which the bolt 20 barely passes, but openings 36, 42 are made to be long holes long in the upward and downward direction or openings of sufficiently larger diameters than that of the bolt 20. When the bolt 20 is turned, its seat 54 is rotated together. By the seat 54 outer periphery butting against an upper piece 26 or the retreat piece 30R, a top plate 12 is pushed downward following the rotation of the seat 54, and its height adjustment is conducted. That is, when the long diameter portion 54a of the seat 54 is butted against the retreat piece 30R, the top plate 12 is lowered, and when the long diameter portion 54a is butted against the upper piece 26, the top plate 12 is lifted up. Metal fittings 16, 18 can be made out by bending- processing out of one sheet plate, and are inexpensive and easy to be worked and their use method is easy to understand.
