Title: Manual elevating equipment
Inventor: MATSUMOTO SHIGERU
IPC: A47B51/00
Filed: 2001-02-01
Abstract: PROBLEM TO BE SOLVED: To solve the problem that unexpected, strong force is required to lift and lower a storage rack made for high places with a manual elevating equipment when the storage rack is supported by a gas damper or a spring. SOLUTION: Manual elevating equipment is equipped with an air damper 31 to apply a load on a rotating arm 7 for supporting an elevating part which supports a main part 11 of a rack and a spring 51 for returning arms with a shape of a torsion spring. When an elevating part 11 is pulled down from its housed position, the air damper 31 starts to work by being compressed as a slider 21 stops at the end of a long hole 7c on a rail after the slider 21 moves along the long hole 7c on the rail as it expands a primary loading spring 38. The spring 51 for returning arms has its one 51b of the arms put on the arm 7 for supporting the elevating part, and the load applied by the spring affects the spring 51 for returning arms when the other arm 51c is fixed at a position after the air damper 31 starts to be compressed.  Both the air damper 31 and the spring 51 for returning arms work most when the main part 11 of the rack comes to a position where the weight of the main part 11 of the rack is sustained by human hands, and they don't operate at the beginning of pulling down. As a result, the main part 11 of the rack can be lifted and lowered easily.
