Abstract
The present invention solves the problem of secure engagement of a thin gauge light handle cover to a light handle. This is possible by way of a simple addition to existing light handle covers. Vacuum structures are a critical improvement of the present invention over the prior art. The prior art has uniformly tried to use a seal between the shield rim and the light handle cover behind which a vacuum would be attempted to be formed. Where the post and shield covering sections have sufficient structural strength, such a seal and vacuum can be obtained. With thin gauge polymers, it is simply not practical.
