Abstract:

The present invention provides a flexible frame for a loading dock shelter. The flexible frame utilizes open channels that are clinched together to serve as supports. The supports are used in side frames that form part of the flexible frame. Each side frame includes a back support, a front support, and in a preferred form, one or more lateral supports that are pivotally connected to both the front and back supports. At least one of said supports is formed from open channels which are secured together, preferably by clinching. The back supports of the flexible frame are mounted to a loading dock wall. The pivotal connection between the lateral support and the front and back supports allows the front support to move relative to the back support when a vehicle comes into contact with the side frame as the vehicle enters the loading dock shelter. The present invention also provides an improved method of making a flexible frame for a vehicle shelter and mounting the flexible frame to a loading dock. The method includes the steps of forming (e. g.

Abstract:

A curtain for a dock shelter that is easily assembled alone and as part of a dock shelter. The curtain includes a sheet that has a pocket mounted thereon. The pocket is adapted to receive a flexible stay and include a slit that inhibits movement of the stay within the pocket. In another aspect, the invention relates to a method of making a curtain. The method includes the steps of securing a pocket to a sheet; forming a slit in the pocket (e. g. , by cutting the pocket); inserting a flexible stay into the pocket; and positioning the stay adjacent to the slit. The invention also relates to a method of making a vehicle shelter and mounting the shelter to a loading dock. The method includes the steps of mounting a frame to the loading dock; securing a pocket to a curtain; forming slits in the pocket; inserting a stay in the pocket adjacent to the slit; and placing the curtain against the frame.
