MODULAR WALL SYSTEM

[0001] This application is a continuation U.S. patent application Ser. No. 13/594,657 filed Aug. 24, 2012, entitled “MODULAR WALL SYSTEM”, which is a continuation-in-part under 35 U.S.C. 120 of International Patent Application No. PCT/CA2011/000541, entitled “MOVEABLE AND DEMOUNTABLE WALL PANEL SYSTEM FOR BUTT-GLAZED WALL PANELS,” and having an international filing date of May 5, 2011, which claims priority to Provisional Application No. 61/331,588 filed May 5, 2010, both of which are incorporated herein by reference in their entireties for all purposes.

[0002] The present invention relates to a wall panel system. More particularly, the present invention relates to a moveable non-progressive mountable and demountable wall panel system for butt-glazed wall panels.

[0003] Fixed wall systems, moveable wall systems, and non-progressive wall systems are very well known in the art.

[0004] Some problems associated with fixed wall systems are the inability to displace and/or move the fixed wall systems once they are mounted; the inability to readily install pass through components (wiring, etc.) after the fixed wall systems have been mounted; and the inability to readily change aspects and features of the fixed wall systems once they are installed. Furthermore, fixed wall systems are also disadvantageous because their installation is quite lengthy. For example, for conventional gyproc walls, one must first install supporting studs, then affix gyproc panels thereto, then plaster thereon, wait for drying of the plaster, sanding subsequently and then finishing the surfaces of the gyproc walls. It is well known in the art that the mounting of such fixed wall systems usually extends over several days and requires a great deal of manual labor, which is thus very inefficient and very cost ineffective.

[0005] Some of the problems associated with moveable wall systems are that, very often, their components are over-engineered (e.g. too heavy), different and specialized tooling is required for assembling such moveable wall systems, and the moveable wall systems generally comprise various different components which are not readily interchangeable. As a result of the above-mentioned, installation of such moveable wall systems is generally quite lengthy and cumbersome. Furthermore, it is well known in the art that such moveable wall systems, by virtue of their design, offer generally very poor sound proofing, light proofing and/or vibration proofing.

[0006] Some of the problems associated with non-progressive wall systems are the inability to independently change, move, and/or alter a particular component of the non-progressive wall system without affecting the other components operatively connected to said particular component. Indeed, by virtue of their design, non-progressive wall systems generally have several components which are intricately connected to one another and thus prevent one particular component thereof from being changed, moved, and/or altered without disturbing the other components of the non-progressive wall system.

[0007] Furthermore, with several conventional wall panel systems, certain components thereof need to be anchored (penetrated, nailed, screwed, etc.) into the floor or the ceiling, which leads to substantial drawbacks, such as holes in the floor and/or corresponding carpet, damages to property, etc. Moreover, it is also known that in some jurisdictions, when components of wall panel systems are permanently affixed to the infrastructure of a building, they become the property of the building owner, which is very undesirable for the owners and/or users of such wall panel systems. It is also known that in large corporations, the different departments need to be restructured on a regular basis, therefore, leading to a frequent reorganization of office spaces, with associated inconveniences. Therefore, it would be very useful to have a prefabricated and modular wall panel construction system that could be assembled without being permanently affixed to an infrastructure of a building, and could be easily moveable and demountable, from one location to another, whether within the same building, or from one building to the next, without leaving any adverse or destructive effects behind.

[0009] Known to the Applicant are also the following foreign documents: CA 2,002,674; FR 1,450,017; FR 1,526,637 and GB 2,171,135 A.

[0010] A movable and demountable wall panel system for framed wall panels, that is, substantially rectangular shaped wall panels comprising opposite top and bottom distance channels, and opposite side vertical posts, with outer covers, having been designed by the Applicant of the present case, is the one described in U.S. Pat. No. 6,688,056 B2 granted on Feb. 10, 2004, to VON HOYNINGEN HUENE et al. More particularly, this document describes a moveable and demountable wall panel system including a plurality of panels each having opposite top and bottom distance channels, opposite left and right vertical posts, a panel covering, a ceiling rail, and an articulating floor channel. The distance channels and vertical posts are affixed to one another by connecting studs in order to form a rectangular support frame of the panel. The articulating floor channel is operatively connected to a bottom portion of the rectangular support frame by left and right glide assemblies mounted into receiving channels of the left and right vertical posts respectively. The articulating floor channel is used for operatively securing the rectangular support frame of the panel to a ground surface. Each vertical post has at least one receiving lip extending along a direction substantially parallel to the vertical axis of the panel.

[0011] Despite several improvements in the field, when assembling office spaces using frameless butt-glazed wall panels, these office spaces are still built using a very old and conventional “stick-built” or “knock-down” approach. That is, one generally goes on site, takes the different measurements, including floor and/or ceiling deviations, where the office space is to be assembled, will then generally manufacture corresponding glass panels of different heights and widths in order to accommodate or compensate for these different particular deviations, and will assemble the office space in a very progressive manner, on site. By assigning each specific glass panel of different dimensions to a corresponding place where it is assigned to, and afterward adjusting positioning, height and vertical displacement of each one of said different types of glass panels in a manual manner, using a plurality of shimmies that are inserted accordingly under each of said glass panels in an attempt to have an overall uniform wall panel assembly, and compensate for possible floor and/or ceiling deviations. Obviously, this approach is not only very long, but quite cumbersome from a logistical point of view, as well as being very labor intensive, and is not very efficient when having to assemble several office spaces in large corporations.

[0012] None of the above-mentioned patents seem to disclose or even suggest a movable non-progressive mountable and demountable wall panel system which is designed to assemble “frameless” butt-glazed wall panels in a very fast, easy, convenient, proper, systematic and cost-effective manner, thereby avoiding the corresponding drawbacks of the “stick-built” approach of conventional wall panel systems.

[0013] Hence, in light of the aforementioned, there is a need for an improved system which, by virtue of its design and components, would be able to overcome or at least minimize some of the aforementioned prior art problems.

[0014] Some embodiments relate to a wall panel of a moveable and demountable frameless wall panel system that is secured between a floor of a room and a ceiling rail secured to a ceiling of the room. The wall panel includes a frameless panel, an upper clamp assembly, a ceiling track configured to be removably inserted into the ceiling rail, a lower clamp assembly, a first height adjustment mechanism secured to the lower clamp assembly, a second height adjustment mechanism, and a bottom floor channel receiving the first height and second height adjustment mechanisms.

[0015] Some embodiments relate to moveable and demountable wall panel systems for defining an office space with a plurality of wall panels disposable in a substantially upright manner between a floor and a ceiling each having respectively a series of uppermost and lowermost deviations, each wall panel having a vertical axis and a horizontal axis, and comprising: at least one prefabricated frameless panel, each panel having a given height defined between top and bottom edges, and a given width defined between left and right side edges, the top edge of each panel being provided with a ceiling track configured for being removably insertable into a corresponding ceiling rail extending along the ceiling and delimiting the office space;

[0016] a bottom floor channel associated with each corresponding panel and being configured for operatively resting against the floor opposite to the ceiling rail extending along the ceiling;

[0017] integrated first and second power-drivable height adjustment assemblies associated with each panel and insertable into a corresponding bottom floor channel, each height adjustment assembly comprising a support edge for operatively supporting a bottom portion of each panel, each height adjustment assembly being selectively operable as to be adjustably raised or lowered, thereby allowing a vertical height adjustment of each panel and a rotational angle adjustment thereof; and

[0018] at least one connecting plate for removably connecting a pair of bottom floor channels, each connector and bottom channel being positioned, shaped and sized with respect to one another for ensuring that the side edges of a pair of neighboring prefabricated frameless panels cooperate with one another in order to define the office space.

[0019] Some embodiments provide a prefabricated, modular and frameless butt-glazed wall panel construction system that can be moveable and demountable, from one location to another, without a “stickbuilt” approach, and without leaving any adverse or destructive effects behind.

[0020] According to another aspect of the present invention, there is provided a method of using the above-mentioned wall panel system and/or components thereof.

[0021] According to another aspect of the present invention, there is provided a method of installing the above-mentioned wall panel system and/or components thereof.

[0022] According to another aspect of the present invention, there is provided an office space having been defined with the above-mentioned wall panel system and/or components thereof. According to another aspect of the present invention, there is provided a kit with corresponding components for assembling the above-mentioned office space.

[0023] According to yet another aspect of the present invention, there is also provided a method of assembling components of the above-mentioned kit. According to yet another aspect of the present invention, there is also provided a method of doing business with the above-mentioned wall panel system, kit and/or corresponding method(s).

[0024] The objects, advantages and other features of the present invention will become more apparent upon reading of the following non-restrictive description of preferred embodiments thereof, given for the purpose of exemplification only, with reference to the accompanying drawings.

[0193] In the following description, the same numerical references refer to similar elements. The embodiments, geometrical configurations, materials mentioned and/or dimensions shown in the figures or described in the present description are preferred embodiments only, given for exemplification purposes only.

[0194] Moreover, although the present invention as exemplified hereinafter was primarily designed for wall systems intended in work environments, for defining office spaces, etc., it could be used with other objects and for other purposes, as apparent to a person skilled in the art. For this reason, expressions such as “work”, “office”, “space”, “wall”, “panel” and any other references and/or other expressions equivalent thereto should not be taken as to limit the scope of the present invention and include all other objects and all other applications with which the present invention could be used and may be useful.

[0195] Moreover, in the context of the present invention, the expressions “system”, “kit”, “set”, “assembly”, “product” and “device”, as well as any other equivalent expressions and/or compounds word thereof known in the art will be used interchangeably, as apparent to a person skilled in the art. This applies also for any other mutually equivalent expressions, such as, for example: a) “mount”, “assemble”, “define”, “build”, “erect”, etc.; b) “wall”, “panel”, etc.; c) “office”, “work space”, “environment”, “structure”, “enclosure”, etc.; d) “rotating”, “driving”, “displacing”, “moving”, “supporting”, “conveying” etc.; e) “interchangeable”, “modular”, “progressive”, etc.; f) “enable”, “allow”, “permit”, etc.; g) “fastening”, “securing”, “attaching”, “anchoring”, “adjusting”, “positioning”, etc.; h) “hole”, “bore”, “slot”, “slit”, “groove”, “cavity”, etc.; i) “rotating”, “pivoting”, “turning”, “rolling”, etc.; j) “ceiling”, “upper, “top”, etc.; k) “floor”, “lower, “bottom”, etc.; k) “glass”, “laminate”, “panel”, “gypsum”, “board”, etc.; I) “positioning”, “spacing”, “locating”, “arranging”, “disposing”, etc.; m) “adjacent”, “neighbouring”, “sequential”, etc.; n) “components”, “parts”, “elements”, etc.; as well as for any other mutually equivalent expressions, pertaining to the aforementioned expressions and/or to any other structural and/or functional aspects of the present invention, as also apparent to a person skilled in the art.

[0196] Furthermore, in the context of the present description, it will be considered that expressions such as “connected” and “connectable”, or “mounted” and “mountable”, may be interchangeable, in that the present invention also relates to a kit with corresponding components for assembling a resulting fully assembled office space.

[0197] Moreover, in the context of the present description, it is also important to make the distinction between a “framed” wall panel which typically consists of a substantially rectangular shape, and comprises opposite top and bottom distance channels, and opposite left and right vertical posts, which make the “frame” of the framed wall panel, and a “frameless” wall panel, which is a wall panel deprived of such distance channels and vertical posts (e.g. a straightforward glass panel not having a frame around it, etc.), as can be easily understood by a person skilled in the art.

[0198] In addition, although the preferred embodiment of the present invention as illustrated in the accompanying drawings may comprise various components, and although the preferred embodiment of the wall panel system as shown consists of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential to the invention and thus should not be taken in their restrictive sense, i.e. should not be taken as to limit the scope of the present invention. It is to be understood, as also apparent to a person skilled in the art, that other suitable components and cooperation thereinbetween, as well as other suitable geometrical configurations may be used for the wall panel system and corresponding components according to the present invention, as will be briefly explained hereinafter and as can be easily inferred herefrom by a person skilled in the art, without departing from the scope of the invention.

[0331] By virtue of its design and its components, the present wall panel system is a moveable non-progressive mountable and demountable wall panel system, particularly well suited for mounting frameless wall panels, such as butt-glazed wall panels, for example, in a very quick, easy and systematic manner, something that is not possible with conventional wall panel systems.

[0332] Indeed, the present invention is the next and innovative generation of wall panel systems, being a considerable improvement over other wall panel systems, such as, for example, the one designed by the Applicant of the present case, and described in U.S. Pat. No. 6,688,056 B2 granted on Feb. 10, 2004, to VON HOYNINGEN HUENE et al., the content of which is incorporated herein by reference.

[0333] Broadly described, the wall panel system (301) according to the preferred embodiment of the invention, as illustrated in the accompanying drawings, is a moveable and demountable wall panel system (301) for defining an office space (303) with a plurality of wall panels (305) disposable in a substantially upright manner between a floor (307) and a ceiling (309) each having respectively a series of uppermost and lowermost deviations, each wall panel (305) having a vertical axis (311) and a horizontal axis (313), and comprising:

[0334] at least one prefabricated frameless panel (315), each panel (315) having a given height (317) defined between top and bottom edges (319,321), and a given width (323) defined between left and right side edges (325a,325b), a pair of top clamp assemblies (326) secured to the top edge (319) of each panel (305) such that the top edge (310) is provided with a ceiling track (327) configured for being removably insertable into a corresponding ceiling rail (329) extending along the ceiling (309) and delimiting the office space (303);

[0335] a bottom floor channel (331) associated with each corresponding panel (315) and being configured for operatively resting against the floor (307) opposite to the ceiling rail (329) extending along the ceiling (309);

[0336] integrated first and second power-drivable height adjustment assemblies (333) associated with each panel (315) and insertable into a corresponding bottom floor channel (331), each height adjustment assembly (333) comprising a support edge (335) for operatively supporting a bottom portion of each panel (315), each height adjustment assembly (333) being selectively operable as to be adjustably raised or lowered, thereby allowing a vertical height adjustment of each panel (315) and a rotational angle adjustment thereof; and

[0337] at least one connecting plate (337) for removably connecting a pair of bottom floor channels (331), each connecting plate (337) and bottom floor channel (331) being positioned, shaped and sized with respect to one another for ensuring that the side edges (325) of a pair of neighboring prefabricated frameless panels (315) cooperate with one another in order to define the office space (303). An example of a resulting office space (303) is shown in FIG. 1.

[0409] In some embodiments, the rail and tile system (950) includes a plurality of rails (952) forming a support framework and a plurality of tiles (954) supported by the framework. The tiles (954) are optionally secured to the rails (952) by fasteners, clips, brackets, adhesives or other securing means as desired. A variety of rail and tile system configurations are contemplated, where FIG. 169 shows rails (952) for supporting a tile (954) or tiles (954) formed of one or more pieces of fabric, FIG. 170 shows rails (952) for supporting a tile (954) or tiles (954) formed of a veneer or laminate material, and FIG. 171 shows rails (952) for supporting a tile (954) or tiles (954) formed of laminated glass that can be used as a marker board, for example.

[0410] FIG. 172 shows a back, perspective view of the system (301) with a second rail and tile system (950B) mounted to the back side of the system (301). The rail and tile system (950B) is shown in FIG. 172 with the tiles removed to show apertures (956B) in the rails (952B) for securing the rails to the panels (305A, 305B, 305C) using the through holes (513). For example, fasteners such as bolts and washers (FIG. 174) are threaded through the holes (513) to secure the rail and tile systems (950, 950B) in place on opposite sides of the panels (305A, 305B, 305C).

[0411] As shown in FIG. 168, wall panel accessories such as a shelf (960) or a table extension (962) are optionally secured (e.g., cantilevered) into the rails (952) or features (not shown) included in the tiles (954). FIG. 173 is an enlarged, cross-sectional view along line 173-173 in FIG. 172 with the second rail and tile system (950B) removed for ease of illustration. As shown, the shelf (960) is inserted into an opening in the rail (952) such that the shelf (960) is cantilevered to the rail (952). As shown in FIG. 168, one or more of the tiles (954) includes an opening or other features for receiving an electrical outlet assembly (964). The electrical outlet assembly (964) includes any of a variety of low, standard, or high voltage outlet means, such as a 110V electrical outlet, a LAN receptacle, an RF cable receptacle, or others.
