BACKGROUND OF THE INVENTION
Restaurants commonly use booth seating because it separates diners and is more intimate. The prior art booth seats have generally been constructed from scratch on site or constructed as stand-alone units in a factory. As a result, if the restaurant wants to change its seating arrangement, it must either make the existing booth seating work or obtain entirely new booth seating. In addition, with the existing booth seating even reupholstering requires extensive disassembly of the booth and the resulting time during which the restaurant must be closed. Thus, booth seating is expensive to modify once it is in place.
BRIEF SUMMARY OF THE INVENTION
The subject invention provides modular booth seating sections which can be interconnected on site which enables them to be moved or reupholstered easily. This is accomplished by providing a generally vertical back section which is connected at its bottom edge to the inner edge of a generally horizontal seat element. A gusset plate has a front leg that is attached to the back element and a second leg that is attached to the seat element.
The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring to FIGS. 1-5 of the attached drawing, a modular booth seat section 10 has a subframe 12 including a rectangular back element 14 which is attached along its lower edge 16 to the inner edge 18 of a planar rectangular seat element 20. The back and seat elements are made from rigid panels, such as plywood. In the embodiment illustrated the back element 14 is generally vertical and the seat element 20 is generally horizontal. The back and seat elements are joined to each other by conventional fasteners. In the embodiment illustrated, the fasteners are double cam and stud connectors 22 which are commonly used in knock-down furniture construction.
An elongate gusset plate 24, which extends diagonally across the intersection of the back and seat elements, has a first leg 26 which is attached to the back element 14, and a second leg 28 which is attached to the seat element 20. In the embodiment illustrated the gusset plate 24 is attached to the subframe elements 14, 20 by screws 30, but other types of fasteners could be utilized. Once joined, the two subframe elements and the gusset plate form a box frame which creates a unitary subframe that is rigid and can withstand normal loads applied to a seat of this type. The gusset plate preferably is an aluminum extrusion, but it could be made of other materials and it could be cast or molded. The subframe 12 rests on a metal or wood support (not shown). A planar rectangular back support 34 having a decorative facing 36 can be attached to the back element to provide a finished surface when the booth back is exposed.
The length of the subframe elements 14, 20 varies depending on the particular application. However, they are meant to be modular sections with multiple subframe sections being joined end to end to create a complete booth. Referring now to FIGS. 6-8, side-by-side subframe sections are joined together by stud cam fasteners 38 similar to the fasteners 22 used to join the back and seat elements together. In order to provide greater strength between adjacent modules, slots 40 are placed in the ends of the back and seat elements 14, 20 and clamp plates 42, having opposed legs 44 which fit into aligned slots 40 in adjacent subframe elements, are attached to the subframe elements. The legs 44 are angled outwardly as they extend inwardly toward the subframe elements such that they pull adjacent modular sections toward one another as the screws 45 which attach them to the back and seat elements are tightened.
If desired, exposed ends of the end module in each booth can be covered by end pieces 46. The end pieces are attached to the back and seat elements 14, 20 by post and cam fasteners 38a. The top of the completed booth is covered by a top piece 48. The top piece is attached to the back element 14 by post and cam fasteners 38b. Posts 50 extend upwardly through the upper end of the back element and top piece 48 to allow a privacy screen (not shown) to be mounted on top of the top piece. Referring now to FIG. 10, the bottom ends of posts 50 extend into openings 52 in the back element and are threaded. Nuts 54 placed on the threaded portions of the posts hold them in place if they are used and allow them to be removed if they are not used. The posts extend through aligned holes in C-shaped plates 56 located on the top edge of the back element and the top of the openings 52 to protect the back element.
The gusset plate 24 has a curved center section 58 which is substantially vertical at one end and substantially horizontal at the other end. The center section acts as a crumb catcher, as will be more fully explained later. Located immediately above the center section 58 is a cup section 60 which receives the bottom end of a seat back 62. The seat back 62 can either have a solid surface, FIGS. 2-4, or be upholstered, FIGS. 14 and 15. The solid surface seat back has a planar rectangular back 64, which preferably is plywood. A rigid plastic or fiberglass shell 66 is adhered to the base with an adhesive. Attached to the lower edge 68 of the seat back is a bull nose 70 which has an outer surface which fits into the cup section 60 of the gusset plate 24. The bull nose is made from a slightly deformable material such as a plastic resin. The upper end of the seat back is removably attached to the back element 14 by strips of hook and loop fastener 72. If desired the seat back 62 can be in two or even three sections, with a top section 62a being attached to the back element 14 entirely by hook and loop fasteners, FIG. 4.
Referring now to FIGS. 14 and 15, if the seat back is upholstered it uses the same back 64 as the hard surface seat back. In the embodiment illustrated the back 64 is first covered with a layer of foam 74, then a thin layer of batting 76 and finally with the upholstery material 78. A metal angle plate 80 which is attached to the seat back 64 protects the ends of the foam layer. The upholstery back is mounted on the subframe in the same manner as the rigid surface back and can also be one, two or three pieces.
Located in front of the center section 58 of the gusset plate 24 is a lip 82 which receives the inner end of a seat bottom 84. Like seat back 62 the seat bottom can have a solid surface, FIGS. 2 and 3, or be upholstered, FIGS. 13 and 14. The upholstered seat bottom 84 is constructed similarly to the upholstered seat back 62. In either case the seat bottom has a planar rectangular seat base 86 which preferably also is plywood. The seat base 86 is attached to a kick plate 88 which extends to the lower edge of the seat bottom 84. The inner end of the seat bottom 84 fits under the lip 82 in the gusset plate 24. The outer end of the seat bottom 84 is attached to the seat element 20 of the subframe 12 by screws 87. A tang 89 formed in the front edge of the gusset plate 24 receives a clip 90 attached to the seat base 86 to hold the inner edge of the seat bottom 84 in place.
Referring now to FIGS. 11 and 12, the gusset plate 24 is too stiff to bend to form a rounded corner in a booth. A corner unit 91 contains a crumb catcher 92 having a curved surface which matches that of the center section 58. The crumb catcher preferably is extruded aluminum but, unlike the gusset plate, has a cross-section that allows it to be bent. The crumb catcher is attached to a subframe seat base panel 96 which has a curved outer edge 98. The crumb catcher is embedded in and attached to a stack of curved wood pieces 102 which are attached to the base panel 96. Back pieces 100, which are configured to mate with the back elements 14 on the seat modules on each side of the corner unit, are attached to the wood pieces 102 to join the base panel 96, crumb catcher 92 and back pieces 100 into an integral structure. A curved corner panel 104 extends between the two back pieces 100 and a stiffener 106 extends between the center of the corner panel 104 and the intersection of the back pieces 100. The floor section 96, back sections 100, corner panel 104, and stiffener 106 are all preferably made from plywood and are joined to one another with cam and stud fasteners. The outside edges of the back pieces 100 are joined to the abutting back elements 14 and the outside edges of the floor section 96 are joined to the abutting seat elements 20 by stud and cam fasteners 38. Because the gusset plate does not extend around the corner unit the seat back 108 and seat 110 base are attached to the corner unit by conventional means.
