Furniture and wall structural system

Claim 2

Apparatus for constructing a skeletal framework adapted to support wall, furniture or other structural panels, said apparatus comprising: a plurality of elongate channel members each having a generally rectangular cross section, one side of each of the channel members defining axial slot means extending the length thereof; a plurality of generally flat elongate cover plates each having elongate, ridged tongue means extending from one side thereof along the length of the cover plate and projecting through the slot means in one of the channel members engaging and latching the channel member with the cover plate to provide a skeletal frame member, said tongue means each having a notch adjacent each end thereof; said cover plates and said channel members each having flanges at the edges thereof, said flanges cooperating to define a plurality of recesses on selected sides of the skeletal frame member formed therewith; and a plurality of spline members each having a generally cubical block portion and at least two orthogonal extensions from the block portion each projecting inside one end of a channel member, said extensions including transverse ridges fitting within the notches in the tongue means of cover plates engaged with the respective channel members to lock the frame members formed thereby into a skeletal framework having a plurality of recesses for supporting the structural panels.

Claim 3

Apparatus as recited in claim 1 wherein the axial slot means comprises a relatively narrow slot extending the length of each elongate channel member, and wherein the tongue means comprises a unitary projection extending from one side of each elongate cover plate and adapted to engage the slot means.

Claim 4

Apparatus as recited in claim 1 wherein the axial slot means extends transversely across substantially the entire width of the rectangular cross section of each said channel member, and wherein the tongue means comprises a pair of ridged tongue members extending from one side of each cover plate and adapted to engage the slot means.

Claim 5

Apparatus for constructing a skeletal framework adapted to support wall, furniture or other structural panels, said apparatus comprising: a plurality of elongate channel members each having a generally rectangular cross section, one side of each of the channel members defining axial slot means extending the length thereof and the other opposite side having a pair of orthogonal flanges extending from each edge thereof, said flanges being coplanar with the sides of the channel member forming the associated edge; a plurality of generally flat elongate cover plates each having elongate, ridged tongue means extending from one side thereof along the length of the cover plate and projecting through the slot in one of the channel members engaging and latching the channel member with the cover plate, said tongue means each having a notch adjacent each end thereof, said cover plates each having a pair of orthogonal flanges extending from each edge thereof, one flange of each pair being coplanar with the cover plate and the other flange of each pair directed opposite from the tongue means so that each engaged cover plate and channel member in combination provide a skeletal frame member having four orthogonal recesses on the respective sides of the frame member defined by adjacent pairs of flanges; and a plurality of spline members each having a generally cubical block portion and at least two orthogonal extensions from the block portion each projecting inside one end of a channel member, said extensions including transverse ridges fitting within the notches in the tongue means of cover plates engaged with the respective channel members to lock the frame members formed thereby into a skeletal framework having a plurality of recesses for supporting the structural panels.

Claim 6

Apparatus for constructing a skeletal framework adapted to support wall, furniture or other structural panels, said apparatus comprising: a plurality of elongate channel members each having a generally rectangular cross section, one side of each of the channel members defining axial slot means extending the length thereof and the other opposite side having a pair of orthogonal flanges extending from each edge thereof, said flanges being coplanar with the sides of the channel member forming the associated edge; a plurality of generally flat elongate cover plates each having elongate, ridged tongue means extending from one side thereof along the length of the cover plate and projecting through the slot in one of the channel members engaging and latching the channel member with the cover plate, said tongue means each having a notch adjacent each end thereof, said cover plates each having a pair of orthogonal flanges extending from each edge thereof, one flange of each pair being coplanar with the cover plate and the other flange of each pair directed opposite from the tongue means so that each engaged cover plate and channel member in combination provide a skeletal frame member having four orthogonal recesses on the respective sides of the frame member defined by adjacent pairs of flanges; and a plurality of spline members each having a generally cubical block portion and at least two orthogonal extensions from the block portion each projecting inside one end of a channel member, said extensions including transverse ridges fitting within the notches in the tongue means of cover plates engaged with the respective channel members to lock the frame members formed thereby into a skeletal framework having a plurality of recesses for supporting the structural panels.

Claim 7

Apparatus as recited in claim 4 wherein the axial slot means comprises a relatively narrow slot extending the length of each elongate channel member, and wherein the tongue means comprises a unitary projection extending from one side of each elongate cover plate and adapted to engage the slot means.

Claim 8

Apparatus as recited in claim 4 wherein the axial slot means extends transversely across substantially the entire width of the rectangular cross section of each said channel member, and wherein the tongue means comprises a pair of ridged tongue members extending from one side of each cover plate and adapted to engage the slot means.

Claim 9

Apparatus as recited in claim 5 wherein the tongues of the cover plates are arrow-shaped so that the head portion of the arrow-shaped tongue projects totally through the slot in the engaged channel member to rigidly lock the cover plates to the respective channel members.

Claim 10

Apparatus as recited in claim 4 wherein the outer surfaces of the extensions are conformed to the inner surfaces of the channel member except adjacent the slot in the channel member to minimize movement of the frame member with respect to the associated spline member.

Claim 11

Apparatus as recited in claim 4 wherein the interior surfaces of the channel members include a plurality of grooves, and wherein the extensions include a plurality of ribs engaging said grooves to minimize movement of the frame member with respect to the associated spline member.
