Abstract
Abstract A building structure comprising a lattice-like network of support elements connected together at junctures to form a three-dimensional frame supporting a fabric-like canopy or skin laid thereover as an enclosure and wherein a resilient ball-like buffer is supported by the frame at each juncture point to engage the canopy and thus to prevent its direct engagement with the frame at the juncture points to reduce its wear and stress.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
137 words
A building construction including a lattice-like network of support elements connected together at junctures to form a three-dimensional frame for the support of a fabric-like canopy laid thereover as an enclosure which is secured along its bottom edge, a plurality of hollow and resilient ball-like buffers, each of which is supported by the frame at a point of juncture of some of said support elements to engage the canopy and thereby to prevent the said canopy from direct engagement with the frame, particularly at the said juncture point, and at least one of the support elements at each juncture of such elements comprising a conduit connected to the buffer at the juncture point and also connected with a source of gas under pressure whereby all of said buffers are gas filled at the pressure of said source.

A building construction including a lattice-like network of support elements connected together at junctures to form a three-dimensional frame for the support of a fabric-like canopy laid thereover as an enclosure which is secured along its bottom edge, a plurality of hollow and resilient ball-like buffers, each of which is supported by the frame at a point of juncture of some of said support elements to engage the canopy and thereby to prevent the said canopy from direct engagement with the frame, particularly at the said juncture point, and at least one of the support elements at each juncture of such elements comprising a conduit connected to the buffer at the juncture point and also connected with a source of gas under pressure whereby all of said buffers are gas filled at the pressure of said source.
Claim 3
Dependent Claim
77 words
The improvement in building construction as set forth in claim 1 wherein certain of said conduit-support elements are connected together in series with each other to define a structural branch in parallel relationship with another similarly formed branch of series connected conduit support elements, and wherein a valve is mounted between said source and said branch and operable to close and prevent flow into said branch in the event of rupture and severe loss of pressure therein.
