Title:
SUCTION DISK AND METHOD FOR INCREASING RETENTION FORCE OF SUCTION DISK
Document Type and Number:
Japanese Patent JP2009287767
Kind Code:
A
Abstract:

To increase retention force by improvement since returning force is weak in a good fitting material although a normal pressing suction disk comprises a cup shape section and an attachment part provided outside thereof by integrally forming soft resin, material is uniform, and material is selected for improving fitting to a contacted surface.

An annular fin 1 of a shape cut off with a center part of the suction disk is formed and a column 2 slightly larger than a hole made by the cut-off is inserted in the hole 1a. When the suction disk is pressed to be a flat shape and is installed, stress from the annular fin 1 to return acts on the column 2, the thickness increases and hardness of a part near a center increases. By this reason, retention force of the suction disk is increased.
