The following description is provided to enable any person skilled in the extrusion field to ~ake and use the invention and sets forth the best modes contemplated by the inventors for carrying out their invention.
Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a relatively economical, reliable, and rugged hinge assembly that can be used with different forms of panel configurations.
Referring to Figures 1 and 2, examples of the hinge assembly 2, 2' are disclosed and include a first hinge member 4, 4', a second link member 6, 6', and a third hinge member 8, 8'. Each of these hinge members can be extruded from any thermal plastic synthetic polymer composition material suitable for this application, such as slightly plasticized polyvinyl chloxide, only slightly plasticized polyvinyl acetate, and copolymers of both of them, vinyl and the like. These members could also be extruded out of metal such as aluminum alloys.
As can be seen, the first and third hinge members 4 and 8, respectively, are preferably identical, to save tooling and production costs, and are secured onto coupling ends 10 and 12 of the link member 6. A web portion 7 interconnects the coupling ends 10 and 12.
Each of the respective hinge members 4 and 8 have a cross-sectional arcuate wall 13 defining a cross-sectional arcuate cavity 14 extending from an entrance opening and running along the length of each extruded hinge member. Curvilinear surfaces define the edges of the opening, with one surface being a concave curvilinear surface 16, and the opposite surface being a convex curvilinear surface 18.

As shown in the embodiment of Figure 1, which is particularly adaptable for conne~tion with a relatively thick panel member, when the link member 6 pivots and moves within the arcuate opening, respective stop surfaces 20 and 22 on the exterior faces of hinge members and corresponding stop surfaces 24 and 26 on either side of the link member 6 define the extent of pivotal movement to approximately 90 degrees.

In the embodiment of Figures 2 and 9, which are applicable for relatively thin panels, the individual hinqe members 4 and 8 can be extruded to include fingers 42 and 44 that can be connected to a panel sectlon, e.g., by inserting an edge of a panel section between the fingers 42 and 44. An inner wall portion 43 extends from one finger 42 to the other finger 44 to limit the extent to which a panel section can slide into the area between finqers 42 and 44 and to define an open area 45 between the end wall 47 and the lnn~r wall portion 43.
The entire upper surface 46 can act as a bearing surface, while the side bearing surfaces 48 and So can ~-~ 20 support the weight of the folded hinge members to ; isolate the hinge assembly from compressive forces. The principal design location of the compressive free bearing surfaces on the hinge assembly is to spatially position these surfaces to isolate the link member 6 from compresslve forces in either an extended or folded position. An end cap or retainer member 52 (Figure 10), that can have a perime~ter shape to match the shape of the hinge member, can be friction fit within ~ slot 53 between the fingers 42 and 44 to close one end of the hinge assembly, as seen in Figure 9. Dimples or ridges could be molded to increase the friction fit. For example, a single dimple (which is not in view in Figure 2 but is in view in Figures 9 and 10) may be formed on the portion of retainer member 52 which fits into slot 53.

Since the link member 6 extends across the joint of the respective hinge members 4 and 8 and along the entire hinge assembly, light will not be transmitted through the resulting panel assembly. Additionally, the hinge members 4 and 8 and the link member 6 can have subjectively designed exterior decorative surfaces to provide a highly pleasing configuration from both sides when the panel assemblies are extended.
In the embodiment shown in Figures 1 and 3 through 5, the panel member or segment can be formed with an interior material such as a rigid foam or composite wood 54, with an exterior decorative skin surface material 56 such as a thin aluminum or plastic sheet. The skin surface material 56 can terminate within a retention cavity member 58 that is extruded on the other side of the hinge assembly 2 on the support surface. The skin surface material can be adhered to the panel material 54 and to the extruded hinge member with an appropriate glue. Alternatively, the panel member can be extruded as an integral continuation of the hinge member 2, particularly if the panel member is relatively thin.
Referring to Figures 6-8, an embodiment of the hlnge assembly can be advantageously used in a garage door assembly having a plurality of panel sections with the hinges of the present invention. An appropriate hinge configuration is shown in cross-sectional views in Figures 3 through 5.

The rollers 64 can be guided on respective guide rails or tubes 66 and 68 that can be placed on either side of the entrance opening of the garaqe. While not ~hown, either a second set of rollers or another set of guide rails will restrain horizontal movement of the garage door. A
lo reversible ele~tric motor 67 can drive an axle 70 through a transmission belt drive mechan~sm 72.
Appropriate electronic garage door controls for remote operation of the drive motor 67 are not shown. At either end of the drive axle 70 are take-up pulleys 74 that can drive a wire cable 78 connected to the bottom panel segment 60. The relative arrangement and angular ; inclination of the guide tubes 66 and 68 are such to permit a gravity closing of the garage door. The garage door may be held in opened, closed or partially opened - 20 positions by any suitable door movement inhibiting mechanisms, such as a dead bolt-l~ke structure (not shown). Alternatively, the wire cable arrangement can be mounted (not shown~ to provide both a positive closing and a positive opening of the garage door.
Preferably, during the opening of the garage door, the drive force is applied by the wire cable 78 to only the bottom panel SQ that,the upper p`anels transmit the bearing force of their collective weight through the respective bearing surfaces of each hinge a~sembly, rather than through the hinge assembly 2. Thus, when the garage door is being opened, the respective hinge assemblies are relatively free of stress forces and the ~;~ opening force is transmitted through each of the respective bearing surfaces on each of the panel members. Likewise, when the garage door is lowered, the bearing surfaces, rather than the hinge member, again support the weight of the garage door.

11. PD-0282 Referring to Figure 11, a display panel system 90 can advantageously utilize the hinge assembly 2, described above in either of the configurations shown in Figures 2 and 9 or Figures 1 and 3 through 5 to connect panel assemblies 92a-f. According to the Figure 11 embodiment, a display panel syste~ so includes multiple (6 in Figure 11) rectangular panel assemblies 92a-f.
Each panel assembly 92a-f is provided with a panel segment 96 and a frame assembly 94 (Figure 12).
Preferably, the panel segments 96 are formed from a lightweight material such as a foam covered with a decorative outer surface. It is highly desirable that the display panel assembly 90 be portable so that it can be transported to various trade shows and easily assembled as a back drop for a display. Conversely, the display panel should be easily disassembled in a similar manner. Since there is a desire to make the display panel 9o compact for s~orage or shipment, the respective hinge assemblies 2 should alternate to permit the panel members to rotate into the stacked configuration of Figure 16. As can be readily appreciated, a pair of display panels 92 can be mounted one on top of the other, as shown in Figure 11, so that an upper set of panels and a lower set of panels can be appropriately connected to lncrease the height of the display panel 90, while permitting the portability of each of the display panel sets~and to be one-half the size of the erected display panel 90 for transportation purposes.
Appropriate connecting apparatus, as explained with reference to Figures 17 and 18 can be utilized for ;~ securing the upper and lower panel sets.
A typical panel assembly 92 is shown in the exploded view of Figure 12. Referring to Figure 12, the panel assembly 92 includes a rectangular panel segment 96 surrounded on all four sides by a frame assembly 94.

It will be recognized, however, that elements described as being horizontal may also be arranged in a vertical or other orientation. Likewise, elements described as being vertical may also be arranged in a horizontal or other orientation.
The vertical members 102 and 104 have a configuration similar to hinge members 4' and 8' described above. The horizontal members 98' and 100 are shaped similar to the vertical members 102 and 104 but do not include the curvilinear surfaces 16 and 18 which define the arcuate cavity 14 discussed above with reference to Figures 1 and 2. Rather, the horizontal members 98 and 100 are each provided with three planer surfaces, e.g., 114, 116 and 118 shown with reference to horizontal member 98.
Similar to the hinge members 4' and 8' described above, the horizontal and vertical frame members 98, 100, 102 and 104 are each provided with fingers 42 and 44 (shown with reference to vertical member 102) that can be connected to a panel section, such as panel 96.
Additionally, the fingers 42 and 44 of each horizontal or vertical member define a slot 121 (in horizontal members) and 123 (in vertical member~) in which a leg of an L-shaped connector member can be inserted, as discussed below.
Each L-Shaped connector member 106, 108, 110 and 112 includes a first leg portion 120, a second leg portion 122 and an intermediate portion 124 connecting the first and second leg portions (shown with reference to L-~haped connector member 106). As shown in Figures 12 and 18, one leg portion, e.g., leg portion 120, is inserted in a slot 121 defined by the finqers of a horizontal member, e.g., horizontal member 98.

It will be recognized that panel assemblles having other configurations of panel members and horizontal and vertical frame members can be designed within the scope of the present invention. The connection between the vertical members 156 and 158 and the horizontal members 160 and 172 is similar to the connection between vertical and horizontal members described above, e.g., with reference to Figure 12.

Embodiments of the above described panel and hinge assemblies can be used as a multiple panel closure for, e.g., a roll-top desk, a garage door, a movable window covering such as for a kiosk window, or the like.
Additionally, a multiple panel configuration can be constructed to provide a movable and foldable wall or room partition. Many multiple panel configurations can be designed so as to readily fold into a relatively compact form, such as shown in Figure 16, for easy storage or shipping. Moreover, components of the panel assemblies can be readily manufactured using relatively inexpensive plastic extrusion techniques, providing very cost effective panel assemblies.

Since the link member 6 extends across the joint of the respective hinge members 4 and 8 and along the entire hinge assembly, light will not be transmitted through the resulting panel assembly. Additionally, the hinge members 4 and 8 and the link member 6 can have subjectively designed exterior decorative surfaces to provide a highly pleasing configuration from both sides when the panel assemblies are extended.
In the embodiment shown in Figures 1 and 3 through 5, the panel member or segment can be formed with an interior material such as a rigid foam or composite wood 54, with an exterior decorative skin surface material 56 such as a thin aluminum or plastic sheet. The skin surface material 56 can terminate within a retention cavity member 58 that is extruded on the other side of the hinge assembly 2 on the support surface. The skin surface material can be adhered to the panel material 54 and to the extruded hinge member with an appropriate glue. Alternatively, the panel member can be extruded as an integral continuation of the hinge member 2, particularly if the panel member is relatively thin.
Referring to Figures 6-8, an embodiment of the hlnge assembly can be advantageously used in a garage door assembly having a plurality of panel sections with the hinges of the present invention. An appropriate hinge configuration is shown in cross-sectional views in Figures 3 through 5.

The rollers 64 can be guided on respective guide rails or tubes 66 and 68 that can be placed on either side of the entrance opening of the garaqe. While not ~hown, either a second set of rollers or another set of guide rails will restrain horizontal movement of the garage door. A
lo reversible ele~tric motor 67 can drive an axle 70 through a transmission belt drive mechan~sm 72.
Appropriate electronic garage door controls for remote operation of the drive motor 67 are not shown. At either end of the drive axle 70 are take-up pulleys 74 that can drive a wire cable 78 connected to the bottom panel segment 60. The relative arrangement and angular ; inclination of the guide tubes 66 and 68 are such to permit a gravity closing of the garage door. The garage door may be held in opened, closed or partially opened - 20 positions by any suitable door movement inhibiting mechanisms, such as a dead bolt-l~ke structure (not shown). Alternatively, the wire cable arrangement can be mounted (not shown~ to provide both a positive closing and a positive opening of the garage door.
Preferably, during the opening of the garage door, the drive force is applied by the wire cable 78 to only the bottom panel SQ that,the upper p`anels transmit the bearing force of their collective weight through the respective bearing surfaces of each hinge a~sembly, rather than through the hinge assembly 2. Thus, when the garage door is being opened, the respective hinge assemblies are relatively free of stress forces and the ~;~ opening force is transmitted through each of the respective bearing surfaces on each of the panel members. Likewise, when the garage door is lowered, the bearing surfaces, rather than the hinge member, again support the weight of the garage door.

Each panel assembly 92a-f is provided with a panel segment 96 and a frame assembly 94 (Figure 12).
Preferably, the panel segments 96 are formed from a lightweight material such as a foam covered with a decorative outer surface. It is highly desirable that the display panel assembly 90 be portable so that it can be transported to various trade shows and easily assembled as a back drop for a display. Conversely, the display panel should be easily disassembled in a similar manner. Since there is a desire to make the display panel 9o compact for s~orage or shipment, the respective hinge assemblies 2 should alternate to permit the panel members to rotate into the stacked configuration of Figure 16. As can be readily appreciated, a pair of display panels 92 can be mounted one on top of the other, as shown in Figure 11, so that an upper set of panels and a lower set of panels can be appropriately connected to lncrease the height of the display panel 90, while permitting the portability of each of the display panel sets~and to be one-half the size of the erected display panel 90 for transportation purposes.
