The panels are made so that they will mount easily onto the support columns, and can be adjusted to the desired angular position at will. Further, the columns are made so that four panels can be supported on one column at 90 to each other. The support members permit the use of curved panels, sound proofing panels, and also have provisions for insertions of glazing strips if less than a full height of panel is desired.

BACKGROUND OF THE INVENTION (1) Field of the invention The present invention relates to portable divider screen assemblies for interior partitions which permit hinging of the screen panels relative to each other.

(2) Prior art Several folding screens have been advanced, and different types of arrangements have been made so that the panels can be set at angles with respect to each other. However, these generally are very complex structures involving a good deal of mechanisms for the fastening members and also a good deal of hand labor in assembly.

For example, U.S. Pat. No. 2,855,037 shows a portable wall or screen which can be used with sections positioned at angles with respect to each other but small resilient inserts that are plugged into fixed holes are used so that only a set number of angular positions can be achieved.

U.S. Pat. No. 538,318 also shows a hinging hospital screen, but here the panels are not readily interchangeable as they are with the present invention.

SUMMARY OF THE INVENTION The present invention relates to a simply constructed divider screen assembly for use in ofiices, commercial buildings of various types, hospitals and the like for forming temporary or semi-permanent interior partitions. The individual panel members can be adjusted at angles with respect to each other. The supports comprise tubes having internal collars that in turn threadably support outwardly extending screws passing through slots in the tube. The panels themselves are supported by placing the screws through keyhole shaped openings. The internal collars can be rotated inside the tube at will, thus permitting adjustment of the panels -with respect to each other. The units are easy to manufacture, low in cost and are interchangeable. There are no unsightly exterior members visible because the rotating elements are completely inside the support tube.

Further objects of the invention include the formation of simply installed glazing channels which can be positioned at angles just like the panels themselves using a cap at the top of the support tube and a small U-shaped hook which holds the glazing channel at any desired angle. Addition- United States Patent O l ICC ally, extruded members only are used for forming the frames for the panels themselves, which reduces cost. Even the interior collars may be formed with extrusions. A sound absorbing panel construction is also presented for specialized uses.

DESCRIPTION OF THE PREFERRED EMBODIMENT A divider screen assembly shown generally at 10 in FIG. 1 includes a plurality of individual panel assemblies 11, 12 and 13 which are supported on connecting posts or tubes 14. The panel assemblies, as shown, are capable of being positioned at different angles with respect to each other, and as shown with panel 13, the panel can assume a curved shape to enhance its appearance and make it fit into modern decor more easily. The support posts or columns 14 are each supported on a separate pedestal 15. The pedestal 15 and the support posts are connected with a tapered fitting member shown in dotted lines at 16 that frictionally locks into a receptacle on the pedestal. The pedestals can be removed if desired and also changed in angle with respect to the support panels. This tapered fitting is a conventional fitting which provides support and stability for the panels.

The support columns 14 each comprise tubes 20 which are, as shown, hollow and circular in cross section. The tubes have panel support collars positioned therein. There are two sets of collars, an upper set and a lower set. Each set has an upper collar 21 and a lower collar 22. These collars are identical in construction. The collars 21 and 22 of each set are positioned in the interior of the tube with a first tubular insert 25 which could be a cardboard tube or other desired insert and a second long tubular insert 26. The inserts 25 and 26 support the sets of collars so that the centers of the collars are aligned with provided annular extending slots, for example slots 27 and 28 respectively see FIG. 5 The slots 27 and 28 extend through the wall of the tube 20. There are two sets of slots 27 and 28, one adjacent the upper portions of each pole 20 for the upper set of collars, and one adjacent the lower portions of the pole for the lower set of collars. The slots are positioned so that the panels are supported at two spaced locations. The showing in FIG. 5 is a typical showing. The upper collars 21 of each set have screws 30 threaded therein and extending through the respective slots 27. The

collars 22, which are the lower of the collars in each of the sets of collars, have screws 31 threaded thereinto and extending through the slots 28. The screws comprise panel support pegs. The collars will rotate inside the tube so that the screws can slide along the respective slots from one end of the slot to the other. As shown in FIG. 6, the screw for each of the collars can actually slide so that the axis of the screw will move through an arc of 901 at a minimum. Thus the slots themselves actually extend more than 90 of arc from end to end.

As shown, the panels 11, 12 and 13 each have a framework made up of channels on the tops, bottoms and the ends thereof. The frame members are fastened together in a known manner. The end channels 32 for each of the panels are made identically, and the top and 4bottom channels for each of the panels have the same cross section as that shown, but the panel 13 of course is bent into a radius so that it is curved. The end channels 32, as shown, have side legs 33, 33 and a joining Web member 34. The web member has an interior recess 35. This recess 35 opens toward the post 20 and has projecting lugs extending toward each other from opposite sides of the recess to form an uprightly extending retainer groove for receiving short retainer inserts or members 36, one that will align with each set of collars and pegs. The retainer members are slid into the groove formed by the lugs, and are held in place in a suitable manner, for example by screws passing into the web. The retainer members 36 cannot slide in up and down directions and will provide support for the panels. The retainer inserts 36 are each provided with a set of inverted keyhole openings 37, typically shown in FIG. 5. The inverted keyhole openings have a wide bottom portion and a narrow neck. As shown, there are two keyholes 37 adjacent the upper portions of the panel, and there is an insert 36 having two keyholes adjacent the lower portions of the panel as well. The reason for having the two support keyholes in each member is to make the channels 32 interchangeable and usable on all panels.

Thus if the panels are being positioned on the right hand side of the post as shown in FIG. 5, the upper keyhole 37 of each insert would be utilized for supporting the panel, and when the panel is supported in the left hand side of the post as shown in FIG. 5, then the lower keyhole 37 would lbe used and mounted over the screw 31. The length of the screws 30 or 31 is adjusted so that the head protrudes from the post the desired amount to provide a tight clamping ofthe edges of web 34 against the post itself. The web is curved slightly to fit the post. The screw heads, for example the screws 31 for the upper collar in each set, are slipped through the large portions of the keyhole openings. The panels are then dropped down so that the shank of the screw slides into the narrow `groove portion of the keyhole. The screw shank rests on the upper edge surface defining the upper end of the slot of the keyhole to support the panel from falling, and the screw head bears against the insert 36 to tightly hold the unit against the post. The panels can be supported in two vertically spaced locations either utilizing the upper collars 21 of each set, or the lower set of collars 22 without having right and left or special panel sections. The screw Shanks are supported on the lower edge of the respective slots 27 or 28 to transfer the vertical loads to the support posts.

The slots 27 and 28, as shown in FIG. 6, provide for a sufficient amount of rotational freedom so that panels 11 or 12 can be positioned at 90 to the solid line position shown. By inserting two screws in each of the collars (the collars are made universal so they have threaded openings every 90), four separate panels can be supported on a single post just as shown in FIG. 6. Two of the panels are shown in solid lines and two are shown in dotted lines for sake of clarity. However, all four panels can be supported in one post as shown and the slots 27 and 28 permit two screws to be mounted into each of the slots,

one at each end, and thus there would be two screws in each collar and two screws in each slot.

Although these collars are shown here with tapped holes, the collars themselves can be made as extrusions with the threads merely extruded along the edges of longitudinally extending openings so that the hole for the screws is continuous from the top to the bottom of the collar, and a continuous extrusion is thus made. The collars would then be cut to the desired axial length and used without further machine work.

In some instances, panels only part of the way up the post are used. Special posts having the upper set of collars lower than that shown are used. A glass unit is used above the short panels. A unique way of fastening glazing channels or members to the posts is shown in FIGS. 8 and 9. The posts are capped with a top cap 40 which has an annular flange 41 that fits over the top end surface of the post, and an inner neck 42 that slides inside the post itself. The ange 41 is supported in the spaced relationship to the top edge of the post with a plurality of small radially extending lugs or bosses 43 which are integral with the cap ange 41 and extend outwardly from the neck 42. The cap is properly centered in the post itself with three axially extending lugs 44 that are attached to the neck and extend down inside the tube to provide the necessary support in the tube to keep the cap centered. A small U-shaped metal clip 45 (which has a spring load) is then placed so that it is hooked over the end surface of the tube and over the web of a glazing channel 46. The cap slides down so the ange 41 lits over the base portion of the U-shaped wire and holds it in place in the tube. Positioning the wire between two of the lugs 43 keeps the Wire in place. Thus, very simply, a glazing channel 46 is held into place against the side of the tube it is to be supported on, and the channel can then hold a piece of glass 47 so that a glazed panel can be made.

Shown in FIG. 7 is a typical cross section of a sound prooiing panel which can be used with the screen of the present invention to minimize cost. This particular construction has been found to ywork very well to minimize sound transmissions of both high and low frequency. The panel, for example panel 11, is a sandwich type construction and on opposite outer sides there is a layer of porous surface fabric, as shown, carpeting 50 which has a suitable backing, and a pile surface. After the carpeting cornes a layer of pegboard or perforated hard board `51 which has openings therethrough spaced every so often, and then in the sandwich construction there are layers of foam 52 and finally a center member made up of corrugated cardboard 53. The center cardboard is imperforate, and prevents low frequency sounds from passing through the panel, and most of the high frequency sounds are absorbed in the carpeting. The foam also absorbs low frequency and high frequency sounds. The pegboard layers 51 give structural strength and rigidity to the panel so that it has stability. This type of construction is economical to make, very attractive because the carpeting can be made in any types of colors, and has a texture that is pleasing, and greatly minimizes any sound transmission bet-Ween compartments or areas separated with the panels.

Thus the entire assembly gives a portable attractive divider assembly thatcan be positioned in angles, can hold four different panels in a corner construction, gives ease of hinging, and also provides for the insertion of glazing channels without modication of a support post. The panel construction minimizes sound conduction and transmission to greatly aid in objectionable noise transmission between the areas separated.

The hinge members are completely hidden from view so no unsightly members are present. The frames it tightly against the posts to also insure maximum beauty.

It should be noted that in place of carpeting, the layers 50 can be felt or other cloth which will help to absorb sounds.

Also, the posts 14 themselves can be tapered to tit into the receptacles on supports 15, if desired.
