Description
Background of the Invention
This invention relates to a panel construction.
More particularly, it relates to the construction of panels of the type shown generally in Swedish Pat. No. 371,740 (application 7300610-8, filed Jan. 17, 1973) of Formfac International AB.
A panel of this type is provided at one edge with an outwardly facing arcuate surface covered with a mass of small hook members adapted to engage a mass of complementary members on an arcuate edge of another panel. In this way the panels may be connected by merely pushing together the respective edges. The edges of the panels may also be rotated against each other, while remaining connected, to vary the angle of the panels one to the other.
Summary of the Invention
An aim of the present invention is to provide in panels of this type improved ease of assembly, panel size flexibility, panel stability, and other advantages. A further aim is to provide special standard hardware which may be easily applied to the panels.
The invention provides a panel having a special frame construction facilitating the connection of the frame members at the corners and, at the same time, providing for the mounting of a special leg-retaining bracket. The frame is also constructed to receive and retain the edges of the panel which it frames. It is also constructed to receive cap members provided with burr fastener means for connecting the panel to other panels and for providing a finish to the edges of the panel.
Each frame member has a web and side flanges extending inwardly and outwardly of the web. The inner side flanges form between them a channel for receiving the edge of the panel. The outer side flanges terminate in inwardly extending flanges forming a hardware enclosure and for receiving a cap member. Extending outwardly from the web are a pair of mounting flanges spaced from each other and from the side flanges. The sides of these flanges facing each other are provided with at least one registering hardware receiving groove.
The ends of the frame members are mitered and abutted together at the corners. Angle members engage in grooves of the corner abutting frame members and are secured to the respective webs so as to provide a strong corner joint.
The elongated base of a leg mounting bracket in slid into the grooves at the bottom of the vertical frame member and secured to the web of this member, with a leg protruding below the bottom horizontal frame member to receive a supporting foot.
In its preferred form, the foot supporting bracket is made up of a flat elongated bar formed to have a flange at each end and an intermediate part having connector receiving openings. An elongated leg mounting member, connected to both flanges, extends lengthwise of the bar parallel to it and has one end extending through an opening in one flange and extending beyond it to provide a foot mounting leg. An intermediate part of the foot mounting member is narrowed to provide access to openings in the bar. The leg is preferably tubular and threaded outside and inside.
Another feature of the invention is an aesthetic enclosure structure for the leg. The structure is made up of telescopically inner and outer cup members enclosing the leg. One cup member is inverted and has a cap provided with an opening receiving the leg and a downwardly extending skirt. The other cup member has a skirt slideable against the one cup member and a cap having an opening surrounding the leg and bearing against the foot part whereby the other cup member can move up and down telescopically on the one cup member, as the foot is raised or lowered.
A further preferred feature of the invention is to provide a cup member having a skirt as a cap provided with a central opening and surrounding the central opening with a detachable annular part removable to provide a larger opening.
Among the features of the invention, therefore, are the overall construction of the frame including the corner joint, the construction of the frame members themselves, the preferred leg mounting bracket and the way it is mounted on the frame and the telescopic leg enclosure.

Description of the Preferred Embodiments
In accordance with the invention, a panel A is provided with a base frame made up of similar frame members B, B.sub.1 and B.sub.2 at the vertical margins and top horizontal margin of the panel and a frame member B.sub.3 along the bottom horizontal margin.
The frame members are preferably aluminum extrusions. They are mitered at each end and the mitered corners of neighbouring extrusions abut to form secure joints at the corners of the panel.
As shown, in cross-section, in FIG. 2, the member B has a web 15 and, perpendicular to it, side flanges each having an inner part 17 extending inward and an outer part 19 extending outward of the panel. The side flanges 19 have inward extensions 20 which terminate in substantially U-shaped ends 21 and form the sides of a hardware enclosure.
Extending outwards perpendicularly from the web 15 are flanges 23 equally spaced from their respective adjacent flanges 19 and from each other. Each flange 23 has extending along its length spaced apart longitudinal ribs 25 and 27. Each rib 25 forms between it and the web 15 a groove 29. Each rib 27 forms between it and the rib 25 a groove 31. The extrusions B, B.sub.1 B.sub.2 and B.sub.3 are of the same construction. The bottom horizontal extrusion B.sub.3 differs in the U-shaped end on the inward extensions 20a which are replaced by a rather L-shaped end 20c (see FIG. 7). The flanges 23 serve to stiffen the web 15 against flexure, as well as providing connecting and mounting functions to be described.
At the bottom left hand corner of the panel, where the mitered adjoining ends of the members B and B.sub.3 abut, the groove 29 of each receives one leaf of an L-shaped corner strap 33 to hold together the abutting corners of the respective extrusions B and B.sub.3. Each strap 33 had holes 34 through which self-tapping screws are screwed into the web 15 of the underlying extrusions. The connection between the ends of the extrusions B and B.sub.1, B.sub.1 and B.sub.2, and B.sub.2 and B.sub.3 are similarly effected.
The groove 31 at the lower part of the vertical extrusion B receives a bracket C made up of a narrow rigid elongated body 35 having parallel sides and at one end a flange 37 and the other end flange 39. The flanges 37 and 39 are provided with respective openings receiving a tube 45 extending between the respective flanges and having its ends welded to them as at 41 and 43. The tube 45 has a threaded leg 47 extending beyond the flange 39. The leg 47 is also internally tapped. An intermediate part 51 of the tube 45 is flattened to give access to fastening openings 53 on the body 35.
The body 35 of the bracket C slides snugly into the groove 31 of the extrusion B, and once in position, the body 35 is connected to the web 15 by self-tapping screws 56 extending through the openings 53 in the body 35 and into the web 15.
A glide D has a head 55 and a threaded shank 57 screwed into the tapped end 47 of the bracket C. The screen A can be levelled by screwing the glide in or out as required in coordination with the glide at the other end of the panel.
For aesthetic purposes a covering structure is provided to enclose the threaded shank 57. This structure is adjustable in height to conform with the adjustment of the glide. The covering structure includes an inner cup E, having a cylindrical skirt 59 and an end cap 61 provided with a central opening 62 receiving the leg 47.
A flexible washer 64 attached to the underside of the cap 61 surrounding the opening 62 engages the leg 47 so that the cup can be pushed on to the leg, but has to be screwed off. An outer cup F has a skirt 65 having a sliding fit on the outside of the cup E. The cup F has an end cap 67 provided with a central opening 69 having a loose fit on the shank 57 of the glide D.
The cap 67 of the cup F (see FIG. 8) may also be provided with a circular weakened ring 71 defining a disc 73 which can be pushed out of the cap 67 by rupturing the weakened ring. Removing the disc 73 forms a larger opening.
This larger opening is employed in the case of the construction where a foot G is attached. The foot G has an upwardly extending tube 75, internally tapped at 77, so that the tube 75 threadably engages the threaded leg 47. The openings left by removal of the disc 73 centers the sleeve 75 over the leg 47. A weld 78 secures the tube 75 to the foot G.
The panel A can be levelled by raising or lowering the foot G in conjunction with a foot at the other end of the panel, by rotating it clockwise or counterclockwise, as the case may be. The inner cap E remains fixed relative to the leg 47. The outer sleeve moves up or down with the foot G as with the glide D.
Mounted on the frame members B, B.sub.1 and B.sub.2 are elongated cap members H, H.sub.1 and H.sub.2. Thse cap members are each made up of an elongated shell having a body 80 of springable material, semi-circular in cross-section and having terminal inwardly extending flanges 81 provided with hooked ends 82 for engaging the ends 21 of the frames B, B.sub.1 and B.sub.2. The members H are sprung into place as best shown in FIG. 2.
The vertical frame members H and H.sub.2 are provided with a covering of a burr fastener fabric 84, for example BELL-TOUCH fabric. The surface of the vertical cap member H is provided on the surface thereof with the male fabric and the surface of the cap member H.sub.2 with the female type fabric so that the panels can be releasably connected to the vertical cap members of adjacent panels provided with complementary fabric.
The bottom frame member B.sub.3 instead of being capped with a cap member, is finished with an elongated wooden plug 85 which engages between the flange ends 20c to form with the inwardly extending flange 20a a flat face on the bottom of the panel frame.
The panel A proper is made up of sound absorbing material as well known in the art. The panel is provided with a marginal part 86 which is firmly held within the channel formed by the web 15 and the flange parts 17. A fabric cover 87 is applied over the panel A and extends over the sides of the frame members B, B.sub.1, B.sub.2 and B.sub.3 and is held thereto by adhesive strips 88. The margins of the cover 87 may be turned in with the margins of the fabric 84 and held in the gap between the flange 20 of the frame member B and the flange 81 of the cap member H. At the bottom, the cover 87 is turned in and held between the flange 20c of the frame member B.sub.3 and the plug 85.
The selection of appropriate materials from which the various parts are made will be apparent to those skilled in the art, for example the frame members are preferably aluminum extrusions. The bracket C is of any suitable metal. The cap members H may be aluminum extrusions. The cup members E and F may be of plastic material.
