Another object is to provide a portable partition system which may be readily set up anywhere to provide booths, offices, reception rooms, etc.
' Another object is to provide a partition system which is designed to visually close the joint between panel sections to insure privacy.
Another object is to provide a portable partition system of the type in which appliances, electric plugs, speakers, etc., can be installed in the partition.
Another object is to provide a partition system which may have acoustical properties and which is strong and durable.
Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings, wherein:
FIG. 1 is a fragmentary view taken on the line 1-1 in FIG. 2, showing parts in section and parts in plan looking at the partition system from above.
FIG. 2 is a view partly in elevation and partly in section taken on the line 22 in FIG. 1.
FIG. 3 is a fragmentary sectional view taken on the line 3-3 in FIG. 1.
FIG. 4 is a view partly in elevation and partly in section taken on the line 4-4 in FIG. 3.
Referring now more particularly to the drawings, the portable partition system comprises the individual vertical wall or partition sections and the elongated vertical hinge members 12 which connect the partition sections together in edge-to-edge relation.
The partition sections 10 are of identical construction. Each partition section 10 comprises an elongated top channel 14 extending lengthwise of the section, having a horizontal base 16 and vertically downwardly extending side flanges 18. The base 16 has an extension at one end providing a hinge portion or leaf 20 and formed with a circular hole or aperture 22. The base 16 has a horizontal extension at the opposite end which is in the plane of the base and provides a hinge portion or leaf 24 which has a circular hole or aperture 26. The hinge portion 20 is horizontal but spaced below the plane of the base 16 a distance substantially equal to the thickness of the base.
Each partition section 10 also has an elongated bottom channel 28 extending lengthwise of the section, having a horizontal base 30 and side flanges 32 extending vertically upwardly from the opposite side edges of the base. The base 30 has a horizontal extension at the same end of the panel section as the top hinge portion 20 which is in the plane of the base and provides a bottom hinge portion or leaf 34 which has a circular hole of aperture 36 vertically aligned with the aperture 22 in the hinge portion 20 of the top channel 14. The metal surrounding the hole 36 is stamped or flared upwardly to provide a cylindrical integral tubular hinge pin or plug 37 of circular cross section. At the opposite end, bottom channel 28 has an extension providing a bottom hinge portion or leaf 38 having a circular hole or aperture 39 vertically aligned with the aperture 26 in the top hinge portion 24. The bottom hinge portion 38 is horizontal but is offset upwardly from the plane of the base 30 by a distance substantially equal to the thickness of the base.
Each panel section has the laterally spaced side facings or panels 40 and 42 which extend substantially vertically and are welded or otherwise secured to the outer surfaces of the depending flanges 18 of the top channel 14. The opposite ends of these panels 40 and 42 have right-angle vertical flanges 44 turned inwardly toward one another.
' Vertical strips or channels 46 close the ends of the partition sections. They are arranged so that the bases of the channels extend transversely between the side panels 40 and 42, having right-angle flanges 48 secured in surface-to-surface relation to the inner surfaces of the side panels 40 and 42 by any suitable means, such as welding. The channels 46 open outwardly as shown, and together with the flanges 44 provide a recess 49 for the hinge member 12.
The side panels 40 and 42 in this instance extend for a portion only of the vertical height of the partition sections, extending downwardly from the top channels but terminating above the bottom channels. The space beneath the side panels is closed by the laterally spaced base plates 50. Base plates 50 have upper vertical portions 52 which extend along the inner sides of the lower portions of panels 40 and 42. Such base plates are bent inwardly at 54 and have the lower vertical portions 56 spaced inwardly from the upper portions 52 and extending vertically downward along opposite sides of the flanges 32 of the bottom channel 28, being welded or otherwise suitably secured to the side flanges 32.
The interior space of the partition sections may if desired be filled with a suitable acoustical material such as a honeycomb core or sandwich having a suitable acoustical substance contained in the cells of the honey-comb. For better acoustical properties, the side facings or panels 40 and 42 may be perforated. The provision of acoustical material, while desirable, is not essential to this invention.
The partition sections 10 are connected together edge to edge by the elongated vertical hinge member 12 which is a tubular pipe or cylinder of circular cross section which extends substantially from top to bottom of the partition system. The partition sections are arranged so that the top hinge portions 20, 24 overlap with their apertures aligned, and also so that their bottom hinge portions 34,38 overlap with their apertures overlie and rest upon the upper end of the tube 12 with their apertures aligned with the tube. The tube can be installed by first overlapping the bottom hinge portions 34 and 38 so that the flaring plug 37 fits up through the aperture 39, then leaning or tilting the partition sections away from one another sufficiently to allow the tube 12 to be placed in position between the adjacent ends of the partition sections with its lower end over the plug 37, and then returning the partition sections to upright position with their upper hinge portions and 24 overlying one another and resting upon the upper end of the tube as shown in FIG. 2. The assembly is completed by the removable hinge pin or plug 62 which has the tubular section 64 of circular cross section inserted through the apertures in the upper overlapped hinged portions 20 and 24 into the upper end of the tube. The plug 62 has the annular outwardly extending flange 66 which in assembly rests upon the overlapped hinge portions 20 and 24.
It will be clear from the foregoing that the partition sections are pivotally connected to the hinge member 12 by the flaring integral plug 37 at the bottom and by the removable plug 62 at the top, and are free to pivot or swing with respect to one another about the axis of the hinge member 12 through an angle up to about 40.
It will be noted that the side panels 40 and 42 partially overlap the pipe or tube 12 to visually close the joint between the partition sections. The flanges 44 at the opposite ends of the panels terminate close to the tube 12 to more fully visually close the joint. These flanges 44 cooperate with the channels 46 to form recesses 49 in which the tube 12 is partially received. Thus as seen in FIG. 1 there would be no possibility of seeing through the joint between the partition sections even when they are disposed at a substantial angle to one another. Thus complete privacy is assured in the sub-divided space on either side of the partition system.
