Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
152 words
A constructional arrangement comprising: a thin walled guide component, substantially U-shaped guide strips extending along opposite edges of said guide component opening toward each other, a filler component extending between said opposite edges of said guide component and received by said substantially U-shaped guide strips, the edges of said filler component which are received by said substantially U-shaped guide strips are of substantially the same configuration as the guide strips, at least one further guide component, grooved strips and spring means disposed between said guide components, said guide strips, and said grooved strips to form hollow double constructional elements, said guide strips of said two guide components being arranged to face towards one another, adjacent guide strips of said two guide components being coupled by means of said grooved strips, said grooved strips being situated opposite one another being pressed into said guide strips by said spring acting between said grooved strips.
