ABSTRACT:
A clamping device, utilizing an L-shaped latch member and one or two coil springs inside a housing, so that when the housing is rotated, it carries the bigger spring and the smaller spring (in case two springs are used) and causes the convolutions of one or both springs to feed under a pin which is firmly attached perpendicular into the round stem of the L-shaped latch, inside the housing. By turning the housing relative to this stem of the L-shaped latch, the springs are forced to feed more of their convolutions under the pin of the stem, until all convolutions of one or both springs under the pin are in a solid compressed form, which means that the L-shaped latch has been drawn closer and tight with the base of the housing. This constitutes a useful clamping device to hold two panels together, such as a door to its enclosure.
