DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
While the present invention is open to various modifications and alternative constructions, the preferred embodiment 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 of the particular embodiment, form or example disclosed. On the contrary, the invention 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. § 112 (second paragraph).
An example of a moveable panel wall system 10 is illustrated in FIG. 1 and includes a space comprising five wall panel sections 12, 14, 16, 18, 20. The system may include vertical supports 22, 24, 26 to which are attached base and stacker wall panel assemblies 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50. The sections may be of different height and a cabinet 52 may be mounted to one of more of the sections.
A wall panel assembly 54, 56, FIG. 2, typically includes an outer frame, such as the frame 60, and decorative wall panels, such as the panels or tiles 62, 64, 66. As mentioned, these wall panels may be made of wood, plastic or metal and each may display a natural finish, a coating of paint or a layer of fabric wrapped around the panel depending upon the aesthetic appearance desired for the office space.
The frame 60 is rectangularly shaped and made of metal and the two tiles 64, 66 are connected to each side of the frame. Universal tile connectors, such as a top connector 70, are connected to the tiles at their upper horizontal edges and at their lower horizontal edges. The connectors include clips with springy tabs which are designed to engage the frame and keep the tiles in place.
Referring now to FIGS. 3 and 4 the universal tile connectors are shown in more detail. The top connector 70 is illustrated in FIG. 3 and a bottom connector 72 is illustrated in FIG. 4. Each connector includes an identical elongated bracket 74 and each of the connectors include three clips, such as the three top clips 76, 78, 80 of the top connector 70 and the three bottom clips 82, 84, 86 of the bottom connector 72.
The bracket 74 is a stamped or extruded elongated piece having a first or lower portion 90, FIGS. 5-7 in a U-shaped configuration with a base 92, a short arm 94 and a long arm 96. A second or upper portion 98 is in the form of an elongated strip of generally consistent cross section and a middle portion 100 includes an offset 102. The bracket also includes three groups or clusters of openings or apertures 104, 106, 108 where each group, such as the group 104, includes a rectangular-shaped or slot-like opening or aperture 110 and two smaller rectangular-shaped openings or apertures 112, 114 that are nearly square shaped. Each group of openings are arranged to help seat a clip. The slot-like opening is located in the middle portion 100 at the offset 102. The smaller openings are located in the upper portion 98 of the bracket. It is understood that the terms “upper” and “lower” are based on the orientation of the bracket shown in FIG. 5, which is the orientation of the bottom connector. The orientation of the top connector is upside down to the bottom connector so that the U-shaped configuration is uppermost; the structure is identical, just rotated one hundred and eighty degrees. It is also understood that more or less clips and groups of openings may be provided depending upon the length of the bracket. Shorter connectors may only use two clips, for example. The term “opening” is defined here as an aperture or hole as shown in FIGS. 5-7 and 14.
The bracket may extend in length from about twenty-three to about sixty inches, a height of about 1.75 inches, a space between the legs of about 0.285 inches, a thickness of about 0.050 inches and an offset of about 0.082 inches. The height of the short arm is about 0.188 inches and the height of the long arm is about 0.750 inches. A preferable material is aluminum.
Referring now to FIGS. 8, 9 and 10 it can be seen that the top attachment clip is simply and inexpensively constructed. The clip 118 has a generally U-shaped profile with a base 120 and two legs 122, 124. Formed from one of the legs is an extending tab 126 having a bump, bend or protrusion 128 formed for engaging the frame 60, FIG. 2, of the wall panel assembly. The clip is made of steel and is about 0.025 inches thick. This allows the tab to be resilient. The clip also has been formed to include two offset fingers 130, 132 for the purpose of forming an interference fit with the two small rectangular openings of each group of openings in the bracket. The attachment clip is relatively small having a height dimension of approximately 0.90 inches, a width dimension of about one inch and a tab extension of about 0.6 inches.
The bottom attachment clip 150, FIGS. 11-13 is almost identical to the top clip and includes a base 152 and two legs 154, 156. Formed from the leg 154 is an extending tab 158 having a slight bend 160. The tab 158, like the tab 126, functions to connect the connector to the frame of a wall panel assembly. The bottom clip is also made of steel with the same thickness as the top clip so that the tab 158 is resilient. The bottom clip has similar dimensions to that of the top clip and also include two offset fingers 162, 164. The interference fit between the finger 162 and the bottom connector 72 through the opening 112 is illustrated in FIG. 14.
The clips are connected to the bracket by slipping one leg through the slot-like opening of the bracket and when the offset fingers are aligned with the smaller openings corresponding to the slot-like openings, the leg is biased back to cause an abutment between the bracket material bordering the small openings and the fingers.
The top connector and bottom connector are engaged with the top and bottom horizontal edges of a tile and the tile may then be engaged with a frame. Because the top and bottom connectors have the U-shaped portions, they may engage any tile having about a quarter-inch thickness. As mentioned, the tile may be wood and metal and also glass, plastic, natural or painted or covered with material. The tile may be paper or parchment or even a sandwich such as wire screens to either side of a layer of small stones. To help connect a tile to a connector, an adhesive 170, FIGS. 3 and 4, may be placed on the first portion of the bracket.
The above specification describes in detail the preferred embodiment[ s] 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, changing the shape of the bracket or the clips are still considered to be equivalent structures. Further, they 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 invention.
