Title:
SEAL STRUCTURE OF SLIDABLE BOX BODY SLIDING SECTION
Document Type and Number:
Japanese Patent JP2570086
Kind Code:
B2
Abstract:
PURPOSE: To enhance the execution efficiency by providing a bar-shaped elastic body to the end of an outside box to bury a slidable gap between the end of the outside box and the peripheral surface of an inside box and, at the same time, covering between the end of the outside box and peripheral surface of the inside box with an impermeable sheet formed in the shape of an expansible spiral.
CONSTITUTION: An inside box 2 is inserted to the inside of an outside box 1 in a slidable manner, at the same time, a bar-shaped elastic body 4 is fixed to the inside of the end of the outside box 1 to close a gap between the end of the outside box and the peripheral surface of the inside box 2. After that, one end of an impermeable sheet 3 winding a twice-folded sheet is bolted to the peripheral surface of the inside box 2, and the other end thereof is bolted to the end of the outside box 1. Then, in the case the outside box 1 is slid in a direction separated from the inside box 2, the elastic body 4 is followed to the outside box 1 in a state to close a gap, and the sheet 3 is followed to the outside box 1 while unravelling spirals of the sheet. A sealing state remains unchanged before and after a sliding, and the sealing state is not damaged because of the sliding. According to the constitution, sealant can be easily mounted even if the length of the sliding section is lengthed, and damage can be prevented.
