Description:

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to U.S. Provisional Patent Application Ser. No. 60/484,858, filed Jul. 3, 2003, entitled “Modular Office Panel Features,” and invented by David Wright.

TECHNICAL FIELD OF THE INVENTION

The present invention relates in general to furniture, and in particular to privacy screens and related accessories for modular office furniture.

BACKGROUND OF THE INVENTION

Modular office furniture has been provided by rigid panels which are connected together by vertical support members. The vertical support members typically have mounting slots formed on various sides for receiving mounting brackets which secure the rigid panels to the vertical support members. The mounting slots are typically visible from each side of the vertical support members. Various accessories such as shelving and such are mounted in the mounting slots formed into the vertical support members. The mounting slots will face outward from the support members, perpendicular to the plane of the rigid panels, for receiving mounting tabs of the shelving and accessories. Any downward pull on the accessories will pull directly against the portion of the mounting tabs inserted into the mounting slots. The mounting slots are typically formed into steel to provide sufficient strength for mounting the accessories with mounting brackets having tabs whichfit into the mounting slots. The mounting slots are typically visible to a person facing the rigid panels.

SUMMARY OF THE INVENTION

Modular office furniture is disclosed which includes privacy screens provided by rigid panels. The rigid panels include core panels mounted to a rigid frame formed from various support tubed provided by vertical and horizontal tubes formed of aluminum extrusions. The extrusions providing the vertical and horizontal tubes have two slots formed into opposite, longitudinal sides of the extrusions. The two slots preferably each have a substantially rectangular shape defining a groove with a profile which includes two sets of opposed grooves, extending on opposite sides of the slot for the full length of the slots. Various mounting brackets and hinges are supported in the grooves. The grooves also provide a means for attaching accessories, and decorative trim such that the slots are not visible. The horizontal and vertical support tubes are secured together by forming a miter joint with a rigid tube plate extending within the miter joint. The miter joint is provided by forming V-shaped notches in the vertical tubes and V-shaped ends on the horizontal tubes. The V-shaped ends of the horizontal tubes fit flush within the V-shaped notches of the vertical tubes. The V-shaped notches are spaced apart along the length of the vertical tubes for receiving the V-shaped ends of the horizontal tubes. The tube plates extend from the vertical tubes into the horizontal tubes with a threaded fastener securing the tube plate to the horizontal tubes to rigidly secure the vertical tubes to the horizontal tubes. An inner trim is inserted into the slots, and has mounting tabs which extend into the opposed inner grooves of the slots. An outer trim fits in the slots between sidewalls of the slots and the inner trim, with tabs which fit into the outer grooves of the slots. Hinges are also mounted in the slots, with mounting tabs that fit into the inner grooves.

The core panels are also secured to the vertical tubes by means of a mounting assembly which includes a mounting bracket, a core panel pin and a threaded fastener. A longitudinal aperture is provided by a blind hole formed into an end the core panel, preferably parallel to the plane of the main surfaces of the core panel. A transverse aperture is formed to extend transversely through the core panel, and preferably perpendicular to the plane of the main surfaces of the core panels. The transverse aperture intersects and extends transversely through the longitudinal aperture. A core panel pin is disposed in the transverse slot, and has a threaded, transverse through-hole which extends transverse to a longitudinal axis of the core panel pin for aligning with the longitudinal aperture. The core panel pin is preferably wider than the core panel, such that opposite ends of the core panel pin protrude outward on opposite sides of the core panel when the core panel pin is disposed within the transverse aperture. The mounting bracket is preferably U-shaped, having a web portion and two spaced apart mounting ears which extend outward from the web portion in parallel, at right angles to the web portion. Each of the two ears has a pin aperture for receiving the portions of the core panel pin which protrude outward from the core panel, and the web portion has a bolt aperture for aligning with the longitudinal slot such that the core panel pin is extending through the pin apertures in the two ears. The web portion fits against a tube plate secured in the extrusion providing the vertical tube, with the two ears extending outward for receiving one of the core panels between the two ears. The core panel pin extends through the core panel and the pin apertures in the two ears of the mounting bracket, with the threaded, transverse through-hole axially aligned with the longitudinal aperture. A V-shaped notch is formed into the extrusion providing the vertical tube, within which the mounting bracket is received into the slot in the extrusion. An aperture is formed for inserting the tube plate into the extrusion. A threaded fastener is passed through a mounting hole in the tube plate, through the bolt aperture in the web portion of the mounting bracket, into the longitudinal aperture in the core panel, and is secured within the threaded, transverse through-hole of the core panel pin to secure the core panel pin within the core panel, to the mounting bracket, and to the extrusion providing the vertical tube.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a perspective view of a portion of modular furniture 12 having privacy screens provided by panel 14, panel 16 and panel 18, which are secured together. The panel 8 has an upper core panel 20 and a lower core panel 22. A table 24 is shown disposed in front of the panels 14, 16, and 18 of the modular furniture 12. An accessory shelf 26 is mounted to the panel 14. The panels preferably each have rigid frames of support tubes provided by opposed sets of vertical tubes 28 and horizontal tubes 30. The uppermost ones of the horizontal tubes 30 have a top trim 32 which extends longitudinally along the length of the horizontal tubes 30. Hinges 34 are provided between each of the panels 14, 16, and 18. Leveler feet 36 are secured in the lower ends of the horizontal tubes 30. One of the cores 38 is formed with translucent material such that objects may be seen behind the material, such as the chair 40. The panels 14 and 18 have core panels which are opaque.

FIG. 2 is a perspective view of the panel 16 having two vertical tubes 28 which are spaced apart and disposed on opposite sides of the panel 16, and two horizontal tubes 30 which are spaced apart and disposed opposite sides of the core 38. The vertical tubes 28 are joined to the horizontal tubes 30 at V-shaped miter joints having tube plates 62 disposed to extend interiorly within adjacent portions of the vertical tubes 28 and horizontal tubes 30 at corners of the panel 16 to provide a rigid framework for the panel 16. The top trim 32 is mounted to the upper most one of the horizontal tubes 30. End caps 42 are provided in the upper ends of the vertical tubes 28.

FIG. 3 is an exploded view of a corner connection between the vertical tube 28 and the horizontal tube 30, providing a miter joint between the two extruded tubes 28 and 30. An end cap tube button 44 provides a fastener for fitting in an end of the vertical tube 28, and threadingly securing the end cap 42 to the top end of tube 28. The vertical tube 28 and horizontal tube 30 are preferably extruded aluminum tubes formed of the same extrusion 50, and will thus have the same profiles. Slots 52 are defined by substantially rectangular grooves formed to extend on opposite, longitudinally extending edges of the extrusions 50, with the slots 52 being symmetrically formed on opposite edges of the extrusions 28 and extending the full length of the extrusions. Two hinge members 54 are secured in opposite ends of respective ones of the slots 52 for pivotally securing adjacent panels 14, 16, and 18 together. An aperture 60 provides a slot formed into the vertical tube 28 for receiving a tube plate 62.

Panels for privacy screens made according the present invention have several advantages. Core panels are mounted to support tubes secured together to provide rigid support members. Each of the support tubes are preferably formed of the same aluminum extrusion. Tube plates provide structural members within the aluminum extrusions for coupling core panels to the support tubes and for coupled horizontal support tubes to vertical support tubes. Two slots are formed into opposite sides of the extrusion providing the support tubes, each slot having a profile which defines two sets of opposed grooves which extend on opposite sides of the profile in a mutually facing arrangement for receiving tabs of mounting brackets. Vertical and horizontal tubes are joined by V-shaped notches are provided in the vertical tubes and V-shaped ends are formed on the horizontal tubes. The V-shaped ends of the horizontal tubes mate with the V-shaped notches of the vertical tubes to provide a miter connection, with the tube plates extending between the tubes as a primary structural support member for either rigidly securing the support tubes together, or rigidly securing a core panel to the support tube. Inner and outer trim, hinges and wall mounted accessories are mounted in the slots. The inner and outer trim, and the hinges are mounted in the opposed grooves formed into the sidewalls of the slots. Core panels are also secured to extrusions providing the vertical tubes by means a mounting bracket, a core panel pin and a threaded fastener. The mounting bracket fits into one of the slots of the extrusions, and has two ears which extend outward from the extrusion on opposite sides of the core panel. The two ears each have pin apertures for receiving a pin which extends transversely through a transverse aperture in the core panel, with a threaded through-hole in the pin extending traverse to the pin an aligned with a longitudinal aperture formed into an edge of the core panel. A threaded fastener extends through the extrusion, through the mounting bracket and between the two ears, through the longitudinal aperture and is threadingly secured within the threaded through-hole of the pin.

Although the preferred embodiment has been described in detail, it should be understood that various changes, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
