Abstract
Abstract An apparatus is disclosed for holding a plurality of modular components against a surface. A fixture prepositions the components and a vacuum develops a uniform pressure which presses and holds the fixture and objects against a surface. The surface may be curved, vertical, or overhead and since local load concentrations are avoided, fragile ceramic tiles may be installed using the apparatus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
An apparatus for supporting and positioning a plurality of objects in a preselected configuration against a curved surface comprising: a fixture for supporting said objects while said objects are being attached to said curved surface; said fixture being flexible to allow said fixture to conform to said curved surface and said fixture having a plurality of projections extending outward from said fixture for locating and maintaining said objects in a predetermined orientation and spacing as said fixture and objects conform to said curved surface; uniform pressure means for applying a uniform pressure to said fixture and objects; said uniform pressure holding said fixture and objects against said curved surface while said objects are being attached to said curved surface; and positioning means for locating said fixture and objects adjacent to said surface prior to the application of said load means.
Claim 2
Independent Claim
140 words
An apparatus for supporting and positioning a plurality of objects in a preselected configuration against a curved surface comprising: a fixture for supporting said objects while said objects are being attached to said curved surface; said fixture being flexible to allow said fixture to conform to said curved surface and said fixture having a plurality of projections extending outward from said fixture for locating and maintaining said objects in a predetermined orientation and spacing as said fixture and objects conform to said curved surface; uniform pressure means for applying a uniform pressure to said fixture and objects; said uniform pressure holding said fixture and objects against said curved surface while said objects are being attached to said curved surface; and positioning means for locating said fixture and objects adjacent to said surface prior to the application of said load means.
Claim 3
Dependent Claim
39 words
An apparatus as set forth in claim 1 wherein said fixture has a plurality of aperture means exposing the centers of and seams between said objects for inspecting the alinement and positioning of said objects by sight and touch.
Claim 4
Dependent Claim
22 words
An apparatus as set forth in claim 1 wherein said uniform pressure means for applying a uniform pressure is a vacuum means.
Claim 5
Dependent Claim
50 words
An apparatus as set forth in claim 3 wherein said vacuum means comprises a sheet of flexible material impervious to air, securing means for attaching said material to said surface forming an airtight cavity around said fixture and objects, and suction means for creating a vacuum within said airtight cavity.
Claim 6
Dependent Claim
26 words
An apparatus as set forth in claim 4 wherein said flexible material is transparent to aid in inspection of alinement and positioning of fixture and objects.
Claim 7
Dependent Claim
24 words
An apparatus as set forth in claim 1 wherein said positioning means comprises a base supporting an extensible member having a platform attached thereto.
