DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
While the present invention is open to various modifications and alternative constructions, the preferred embodiments shown in the various figures of the drawing will be described herein in detail. It is understood, however, that there is no intention to limit the invention to the particular embodiments, forms or examples disclosed. On the contrary, the intention is to cover all modifications, equivalent structures and methods, and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims, pursuant to Title 35 U.S.C. section 112 (second paragraph).
Referring to FIGS. 1, 2 and 3, three different workstation configurations are illustrated having different arrangements of a panel system. FIG. 1 illustrates an “L Station” 10 having six panels 12, 14, 16, 18, 20, 22, three work surfaces 24, 26, 28, two bookshelves 30, 32 and two pedestals 34, 36.
A “Quad Station” 40 is illustrated in FIG. 2. The Quad Station includes sixteen panels of which only fourteen are shown. These includes tall panels 42, 44, 46, 48, 50, 52, 54, 56 disposed in a cross configuration and smaller outer panels 58, 60, 62, 64, 66, 68. In addition, each station includes three work surfaces, such as the work surfaces 70, 72, 74, two pedestals, such as the pedestals 76, 78 and two cabinets each, such as the cabinets 80, 82.
In FIG. 3 there is illustrated an office arrangement 88 called a “Manager's Office” which includes ten panels 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, several work surfaces, such as the work surface 110, several cabinets, such as the cabinet 112, a bookshelf 114 and a shelf 116. As can be seen in FIGS. 1-3, the partition panels may vary in size and be configured in different arrangements or patterns.
Referring now to FIGS. 4, 5, 7 and 8, there is illustrated two panels 120, 122 connected in FIG. 4 in a linear or one-hundred eighty degrees configuration and the same two panels before connection in FIG. 5. Each partition panel includes a barrier material 124 surrounded by a frame 126. The frame borders the barrier material and provides strength, support and rigidity. Each frame includes side walls, such as the side walls 123, 125. FIG. 7, a front wall, such as the front wall 127, and two front and two rear corners, such as the corners 129, 131 and 133, 135, respectively. The barrier material is extensive and functions to divide space, create privacy and absorb sound.
The panel system described here requires no tools or other fasteners for assembly and for the stability needed. Further, it will be come apparent that assembly is quick and easy and that the system components are inexpensive. Referring now to FIG. 6, there is illustrated a single connector 130 for connecting adjacent partition panels together. The connector 130 has a generally H-shape, including a base 132 and two arms 134, 136 extending in a first direction and two arms 138, 140 extending in an opposite direction. Each set of arms includes an open region between them which enables the two arms to receive a frame, such as is shown in FIG. 7. Each arm includes end barbs or projections 142, 144, 146, 148 at the extended end of the arm and other protrusions or projections 150, 152, 154, 156 for engaging the frame. The interior cross-sectional shape of the connector between a set of arms is essentially identical to the external cross-sectional shape of the frame. The connector may be made of any suitable material, such as aluminum, reinforced plastic or even die cast material. The connector may be formed as part of an extrusion, cut to size, so as to minimize expense of the connector component of the panel system.
The arms of the connector are structured to be able to flex due to the camming action of the side walls of the frame against the end barbs during insertion of the frame into the opening between a pair of arms. When the frame is fully received and the camming action ceases, the arms are able to snap back around the rear corners of the frame to ensure a tight interference fit, such as shown in FIG. 8. The other protrusions abut the front corners of the frame.
The configuration of the connector is such that it enables the connected panels to align in a linear fashion. The linear manner of connection allows the panels to be oriented side by side at an angle of one hundred eighty degrees. Such an arrangement might be used, for example, to connect the panels 14 and 16 of the L Station, FIG. 1.
Another connector embodiment 160 shown in FIG. 11 includes two U-shaped portions 162, 164 and a bridge 165 portion. The construction of the connector 160 enables two panels 167, 169 to align at ninety degrees as shown in FIGS. 9 and 10. As with the linear connector 130, FIG. 6, the right angle connector 160, FIG. 11, includes a first portion with a base 166, two flexible arms 168, 170, each arm ending in a barb 172, 174, and a second portion with a base 176 and two extending arms 178, 180 extending at right angles to the first mentioned arms 168, 170. Also, as with the linear connector 130, FIG. 6, the frames 182, 184 of the panels are received between the arms. During attachment, the arms are cammed outwardly until the frame is fully received at which time the arms snap into an interference fit with the panel frames. This is most clearly shown in FIGS. 12 and 13 illustrating the panels just before attachment and after attachment is complete.
Referring now to FIGS. 14, 15, and 16, the right angle connector is used to connect different height panels 190, 192, 194, 196 in a cross shaped arrangement. A first right angle connector 198 attached panels 190 and 192, a second right angle connector 200 will connect panels 190 and 196, a third right angle connector 202 connects panels 194 and 196 and a fourth right angle connector 204 attaches panels 192 and 194. Of course, other connectors may be used and the panels may be of the sane height, or two of the panels may be of one height and the other two panels of a second height, or three panels may be of the same height and one panel may be of a different height. Any combination of panels may be connected in the fashion just described because of the versatility of the connectors being used.
It is to be noted that the right angle connector 160, FIG. 11, may be modified by shortening the bridge portion 165 so that a different connector with the two sets of arms ascribing an angle of one hundred twenty degrees is formed as shown by a connector 210, FIG. 17, or one hundred thirty-five degrees as shown by a connector 212, FIG. 18. It is to be understood that a connector of any angle from ninety degrees to one hundred eighty degrees may be constructed simply by adjusting the length of the bridge portion.
Other specific cross-sectional frame configurations may also be used besides the square shaped frame shown in FIGS. 4, 5, 7-10, 12 and 13. For example, a frame 220 may have a triangularly shaped cross-section as shown in FIG. 20 with a matching connector 222, FIG. 19, having a cross-section in the shape of an “X”. Or, a frame 224 may have the cross-sectional shape of half an oval or “D” shape as shown in FIG. 22 to match a connector 226, FIG. 21, featuring a complementary cross-sectional configuration.
In FIG. 24 a frame 230 has a half-circle cross-section for mating with a connector 232, FIG. 23, having a back to back “C” shape in cross-section. Another example is shown in FIG. 26 where a frame 234 having a rectangular cross-section mates with a connector 236 having an “H” shape like that of the connector 130, FIG. 6, but with longer arms. Each panel system includes a specific cross-sectional shape for the panel frame and a mating cross-sectional shape for the connectors.
In operation, a workstation using the partition panel system disclosed above may be easily constructed without the need for tools. Instead, two connectors, one high and one low, may be attached to a panel by snapping the two connectors around the frame of the panel. Thereafter, a second panel is located at an angle generally from and including ninety degrees to and including one hundred eighty degrees (depending on the connectors used) and snapped into the connectors. In this fashion, a workstation may be quickly assembled by minimally trained personnel because the system is so easy to use. In addition, the arrangement of the panels may be quickly assembled, or disassembled and reassembled into a different configuration.
The above specification describes in detail several preferred embodiments of the present invention. Other examples, embodiments, modifications and variations will, under both the literal claim language and the doctrine of equivalents, come within the scope of the invention defined by the appended claims. For example, different materials may be used, or different barb shapes, or different angled connectors, and these are considered equivalent structures and will come within the literal language of the claims. Still other alternatives will also be equivalent as will many new technologies. There is no desire or intention here to limit in any way the application of the doctrine of equivalents nor to limit or restrict the scope of the claims.
