Abstract
Abstract A releasable lock support is provided for releasably locking together two components such as a printed circuit board and a chassis. The lock support has a pair of dished flexible flange members which are urged into engagement with the two members to be releasably locked together, and act as spring washers against their respective members. The lock support extends through aligned apertures formed in the members to be joined, and includes a pair of flexible leg members which cooperate with one of the dished flange members to engage the chassis firmly, while the other dished flange member cooperates with a gripping means to firmly seat the flange member against the other member. In the preferred embodiment of the invention, the lock support is a one piece element molded from a suitable insulator material.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
A releasable lock support for releasably locking together two planar components comprising a one-piece element composed of a flexible insulation material, said element having a central body portion, a first dished flange member extending from said body portion and having convexly formed distal ends located below said central body portion, a pair of flexible leg members depending from said first dished flange member and having planar surfaces formed thereon arranged to engage the underside of one of the components to be joined, a second dished flange member extending from said body portion and having concavely formed distal ends located above said body portion, and a gripping member extending upwardly from said second dished flange member, said gripping member having a horizontal planar surface thereon spaced from said second dished flange member sufficiently to snugly engage the second of said components therebetween upon resilient deformation of said second dished flange member.
Claim 2
Dependent Claim
150 words
A releasable lock support for releasably locking together two planar components comprising a one-piece element composed of a flexible insulation material, said element having a central body portion, a first dished flange member extending from said body portion and having convexly formed distal ends located below said central body portion, a pair of flexible leg members depending from said first dished flange member and having planar surfaces formed thereon arranged to engage the underside of one of the components to be joined, a second dished flange member extending from said body portion and having concavely formed distal ends located above said body portion, and a gripping member extending upwardly from said second dished flange member, said gripping member having a horizontal planar surface thereon spaced from said second dished flange member sufficiently to snugly engage the second of said components therebetween upon resilient deformation of said second dished flange member.
Claim 3
Dependent Claim
23 words
