Abstract
Abstract An apparatus for manufacturing furniture by joining panels and making corners, in which at least two panels each having generally parallel generally planar major faces and a generally planar end surface bounding one edge of the major faces are arranged with mold instrumentalities to form a mold cavity bounded in part by the respective end surfaces of the two panels. Plastic material is deposited into the mold cavity and the two panels are bonded together into a corner configuration by the plastic material while the plastic material is confined and shaped into a predetermined configuration. The plastic material preferably is a structural foam material and the mold instrumentalities preferably define an inclined, heated mold cavity in which reactants may form the structural foam.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
Apparatus for manufacturing furniture by joining panels and making corners, the apparatus comprising baseplate means for defining lower terminal ends of mold cavities, a plurality of outer corner mold portions each having an inwardly facing concave surface and being mounted on said baseplate means for cooperation therewith in defining a mold cavity, a plurality of inner corner mold portions each having an outwardly facing convex surface and being mounted on said baseplate means for cooperation therewith in defining a mold cavity, pairs of said outer and inner corner mold portions being mounted for receiving therebetween end portions of two panels which have generally parallel generally planar major faces and generally planar end surfaces bounding edges of the major faces, each said pair of mold portions cooperating with received panels for defining a mold cavity bounded by the respective end surfaces of the two panels and by said cooperating mold portions and said baseplate means, and clamping means for moving one mold portion of each said pair of mold portions relative to the other mold portion of the respective pair for securing panels in mold cavity defining relation therewith.
Claim 2
Dependent Claim
188 words
Apparatus for manufacturing furniture by joining panels and making corners, the apparatus comprising baseplate means for defining lower terminal ends of mold cavities, a plurality of outer corner mold portions each having an inwardly facing concave surface and being mounted on said baseplate means for cooperation therewith in defining a mold cavity, a plurality of inner corner mold portions each having an outwardly facing convex surface and being mounted on said baseplate means for cooperation therewith in defining a mold cavity, pairs of said outer and inner corner mold portions being mounted for receiving therebetween end portions of two panels which have generally parallel generally planar major faces and generally planar end surfaces bounding edges of the major faces, each said pair of mold portions cooperating with received panels for defining a mold cavity bounded by the respective end surfaces of the two panels and by said cooperating mold portions and said baseplate means, and clamping means for moving one mold portion of each said pair of mold portions relative to the other mold portion of the respective pair for securing panels in mold cavity defining relation therewith.
Claim 3
Dependent Claim
71 words
Apparatus according to claim 1 further comprising mold cap means mounted adjacent each said pair of mold portions and movable between an open position for accommodating deposition of plastic material into the corresponding mold cavity and a closed position for defining an upper terminal end of the corresponding mold cavity and thereby confining deposited plastic material during shaping thereof to the configuration of said mold portions and bonding of received panels.
Claim 4
Dependent Claim
47 words
Apparatus according to claim 1 wherein each said pair of mold portions positions pairs of panels received therebetween with the major faces thereof perpendicular and further wherein at least two of said pairs of mold portions are aligned for receiving opposite end portions of a common panel.
Claim 5
Dependent Claim
36 words
Apparatus according to claim 1 further comprising support means for mounting said baseplate means and for moving said baseplate means between work stations for insertion of panels, deposition of plastic material, and removal of bonded panels.
Claim 6
Dependent Claim
76 words
Apparatus according to claim 4 wherein said support means comprise a stationary base, turntable means mounted for rotation on said base, and arm means on said turntable means for bearing said baseplate means, said turntable means and said arm means cooperating for positioning said mold portions in inclined relation whereby plastic material deposited in the mold cavities is confined to rise on an incline and further cooperating for moving said baseplate means among the work stations.
