Background of the Invention
1. Field of the Invention
This invention pertains to room divider systems. More particularly, the invention relates to modular panel arrangements primarily for use in achieving visual and accoustical privacy in office interiors.
2. Description of the Prior Art
Office space is frequently provided which lacks partitioning for individual cubicles. Preexisting office space may be divided with inappropriate sized and configured partitions. Rearrangement of the positioning and the location of office cubicles is beneficial from time to time. This is generally accomplished by unbolting and separating preexisting partitions or other room divider systems. Various connectors have been used, but often multiple types of connectors are required and many tools may be needed to properly install a new arrangement. The rearrangement procedure can be time consuming and inconvenient. It may be desirable to rapidly change the rearrangement of the room dividers to create a temporary office space or to visually experiment with existing space.
Summary of the Invention
A modular room divider system in accordance with this invention generally comprises first and second juxtaposed upright modular panels each having anchoring apertures. A coupling arrangement comprising two spaced apart anchors matable with the panel's anchoring apertures each have extending threaded portions. A central elongated sleeve having internal threads engages the threaded portions of the anchors. Means are provided for rotating the sleeve to cause the spaced apart anchors to be moved towards each other or away from each other, depending upon the direction in which the sleeve is rotated. When the anchors are disposed in the anchor apertures of the respective panels, rotation of the sleeve causes the panels to move towards one another and tightening of the sleeve causes linkage of the modular blocks.
In a more specific example of the invention, the anchors are cylindrical and bolts are embedded in, and extend radially from the anchors. The bolts have opposing threads and the internal threads of the sleeve have portions in opposing directions. Channels are provided from the anchoring apertures to the edges of the panels for receiving the threaded portions and rotatably receiving the sleeve.
Additional features in accordance with this invention include an upright post for joining panels at right angles and for terminating a series of juxtaposed panels. A circular notched wheel is provided for rotating the sleeve. The wheel has an aperture mating with the exterior sleeve surface whereby the wheel is allowed to move along the sleeve so that precise positioning of the sleeve is not needed to cause proper engagement of the modular panels. Adjacent the side of the panel, a recessed upright surface provides a space for receiving the circular wheel. A horizontally disposed clad has a latch mating with a latch on the top of the panel for removably covering the coupling assembly.

Detailed Description
Referring generally to FIGS. 1, 2, 3, 4, 5, 6 and 7, a modular room divider system in accordance with this invention generally comprises upright modular blocks or panels 10 defining a vertical planes. The panels 10 generally comprise wood or composite material. Each panel 10 has upright edges 12 transverse to the plane of the panel 10 and an upright recessed surface 14 parallel to the edges 12 and spaced inwardly from the edges 12, thereby defining a transverse narrow ledge surface 16. Extending from a top surface 18 normal to the edges 12 and the plane of the panels 10, an upright cylindrical aperture or bore 20 extends inwardly from the top surface 18. The bore 20 is disposed in spaced apart relationship to the recessed surface 14 and thus to the edge 12 of the block 10.
Adjacent the ledge surface 16 and in communication with the top surface 18 is a laterally disposed U-shaped sleeve channel 22. Somewhat narrower than the sleeve channel 22 but adjacent thereto is a bolt channel 24 which comprises a lateral surface 26 and two upright facing side surfaces 28 extending to the top surface 18 of the panels 10. The bolt channel 24 communicates between the sleeve channel 22 and the bore 20. Limiting funnel surfaces 30 extend opening into the bolt channel 24 from the sleeve channel 22.
A panel coupling assembly 32 as best viewed in FIG. 3 generally comprises a pair of short cylindrical plugs or anchors 34 typically of molded plastic such as nylon. The anchors 34 have a transverse interior apertures 36 and a square countersunk aperture 37 for receiving a bolt head. Bolts 38 have square heads 39 seated in mating relationship to the countersunk apertures 37 to prevent free rotation of the bolts 38 with respect to the anchors 34. The bolts 38 have opposing right and left hand threads 40 which extend beyond the interior apertures 36 of the cylindrical anchors 34. To distinguish the right from the left handed threads, the anchors 34 are correspondingly color coded as shown by the shaded lines of 34 in FIG. 2. The anchors 34 provide a stress relief for the bolts 38 generally spread across a diameter of the anchors 34 transverse to the panels 10 to allow significant tightening and joining of the panels. The anchors 34 also prevent rotation of the bolts 38.
An elongated square threaded sleeve 42 has opposing right and left hand transverse interior threads 44, 45 extending from opposing ends 42 of the sleeve 42, and a square prismoidal exterior surface 46. Opposite the anchors 34, the threads 40 of bolts 38 are rotatably disposed in mating relationship in the transverse interior threads 44, 45 of the square sleeve 42. The bolts 38 have opposing right and left hand thread directions to mate with the opposing right and left hand threads of the sleeve 42 and so that rotation of the square sleeve 42 causes opposing axial motion of the bolts 38 and thus the anchors 34.
A circular disc or wheel 48 has a central square aperture 50 mateable with and moveable along the prismoidal square exterior surface 46 of the square sleeve 42. The wheel 48 is slideable along the square sleeve 42. The wheel 48 has a plurality of notches 52 along its periphery so that the wheel may be grasped and rotated either by hand or with a ratchet tool.
Each panel has a pair of cylindrical bores 20 disposed in spaced apart relationship and the sleeve channels 22 and bolt channels 24 extending in opposite directions towards opposing edges 12 of the block 10. Adjacent the bores 20 a latch 54 is fastened. The latch 54 has fingers 56 parallel to the top surface 18 of the block 10 and in spaced apart relationship above the top surface 18. A top clad 58 for hiding the coupling arrangement 32 has a cover side 60 and two elongated spaced apart thin narrow latches 62 for covering the coupling arrangement 32. The latch 62 is mateable with the latch 54 fastened to the block 10.
The block 10 has a central sound proofing accoustical material 70 such as spun fiberglass inset on one side and on the opposite side is upholstered with different accoustical material, in this case with a fabric material 72.
With particular reference to FIG. 1 and FIG. 6, a square upright post 80 is used to join panels 10 at right angles. The post 80 typically comprises a square longitudinal aluminum extrusion having four sides 84. Slits 86 centrally disposed on the sides 84 extending from each end 88 of the post on adjacent sides 84 of the extrusion 82. Longitudinal ribs 90 having limit surfaces 92 enclosing facing edges of the slits 86 extend the length of the interior of the extrusion 82. Abutment surfaces 93 are disposed normal to and between the limit surfaces 92 and each slit 86. Apost coupling assembly 94 is similar to that used to join adjacent panels 10 in juxtaposition, however, only one anchor is used, and typically two shorter bolts including a post bolt 96 are used. The post bolt 96 has a bolt head 98 having a dimension close to that of the limit surfaces 92, which prevents rotation of the post bolt 96. The post bolt 96 bears on the abutment surfaces 93 and when tightened, distributes the tensile load of the coupling assembly to the extrusion 82. To allow adjacent flush placement of the post against the panel 10, the sleeve channel 22 of the panel is substantially the length of the sleeve 42 or a shorter sleeve may be used. In addition to joining panels 10 at right angles, the upright post 80 is also used for aesthetic purposes for terminating a series of juxtaposed panels 10.
With particular reference to FIG. 7, the panels 10 are supported by an arrangement comprising a support plate 100 joined at the bottom surface of the panels 10.The support plate 100 has a slot aperture 102 transverse to the panel 10 for receiving a planar upright support element. A slotted tube 104 has a slot adjacent the support plate 100 and receives a generally triangular planar upright support element 106. The support element 106 has extending lateral protrusions 108 extending through the slot aperture 102 of the support plate 100. A glide 110 is joined to and mates with a lower portion of the tube 104.
In use, two panels 10 to be disposed in juxtaposition are moved physically adjacent one another, with the opposing edges of each block facing each other and the sleeve channels 22 of each of the blocks 10 in straight alignment. The coupling assembly 32 is positioned over the sleeve channels 22 and the wheel 48 is rotated so that the square sleeve 42 causes the spacing between the cylindrical anchors 34 to approximately mate with the bores 20, when the edges 12 are disposed in somewhat spaced apart relationship. Then, the wheel 48 is grasped and the anchors are allowed to drop into the bores 20. The bolts 38 then rest in the bolt channels 24 and the sleeve 42 rests in the sleeve channel 22. The blocks 10 are spaced apart from each other somewhat and the wheel 48 is then rotated using the notches 52, either manually or with a leveraging tool which causes the blocks 10 to move towards each other. Engagement of the recessed surfaces 14 against the wheel 48 prevents further motion and causes the blocks 10 to be tightened. The wheel 48 may be rotated by hand or with a wrench tool to obtain adequate leverage.
To join a pair of panels at right angles, the upright post 80 is brought adjacent one of the panels 10, as shown in FIG. 6. The post coupling assembly 94 is dropped with the anchor fitting within the bore of the panel 10, and the post bolt 96 is dropped in the slit 86 of the extrusion 82. The wheel 48 is rotated causing the sleeve 42 to axially move the post bolt 96 and the bolt 38 extending from the anchor 34 together. The identical fastening is accomplished at the bottom of the post 80 and panel 10.
The panels may be supported by placing the triangular support elements 106 on the tubes 104 which rest on the glides 110. The extending lateral protrusions 108 extend through the slot apertures 102 of the support plate 100, and which runs transverse to the panels 10. For asthetic purposes, a base panel 112 may be joined to the panels 10 and thereby cover exposed portions of the coupling assemblies 32 and also may be used to hide, for example, wiring which may be run underneath the panels 10.
While the invention has been particularly shown and described with reference to a preferred example thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
