Modular wall system

[0001] This application is a continuation under 35 U.S.C. 120 of a national stage entry under 35 U.S.C. 365(a) of International Patent Application No. PCT/CA2011/000541, having application Ser. No. 13/581,254, entitled “MODULAR WALL SYSTEM,” and having an international filing date of May 5, 2011, which claims priority to Provisional Application No. 61/331,588 filed May 5, 2010, each 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] An object of the present invention is to provide a wall panel system which satisfies some of the above-mentioned needs and which is thus an improvement over other related wall panel systems and/or assembling methods known in the prior art.

[0015] In accordance with the present invention, the above object is achieved, as will be easily understood, with a wall panel system such as the one briefly described herein and such as the one exemplified in the accompanying drawings.

[0016] More particularly, according to a preferred aspect of the present invention, there is provided a moveable and demountable wall panel system 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;

[0017] 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;

[0018] 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

[0019] 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.

[0020] The present invention is particularly advantageous in that it provides a prefabricated, modular and frameless butt-glazed wall panel construction system that can be moveable and demountable, from one location to another, without a “stick-built” approach, and without leaving any adverse or destructive effects behind.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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).

[0025] 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.

[0173] 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.

[0174] 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.

[0175] 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.; l) “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.

[0176] 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.

[0177] 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.

[0178] 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.

[0325] 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.

[0326] 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.

[0327] 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:

[0328] 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), the top edge (319) of each panel (305) being 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);

[0329] 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);

[0330] 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 by virtue of a pivot axis (459), as illustrated for example in FIG. 18; and

[0387] With respect to the “carpet gripper/seismic floor attachment” embodiment of the present invention, it may have the following components, features, dispositions, interrelations, variants and/or resulting advantages, namely: a) all panels are secured to the floor channel with the threaded carpet gripper; b) holds dimension, keeps system from growing on the job side; and c) set screws are used as carpet grippers, but also to hold the floor channel in place (in seismic areas, the floor channel is fixed with a nut on the set screw and the plate will be bolted to the floor).

[0388] With respect to the “glass post panel” embodiment of the present invention, it may have the following components, features, dispositions, interrelations, variants and/or resulting advantages, namely: a) glass panels are modular unitized panels with a recessed base; b) glass panels accept ¼″ and ⅜″ glass; c) glass panel frame consists of an aluminum or steel slotted post cladded with aluminum extrusions; d) panel to panel connection is achieved by hooking clips inserted into slotted standard punched along the vertical edges of the post; e) there will be a approx ⅜″ reveal between panels; f) top distance channel 2.5″ bottom distance channel 3″; g) height adjustment of about +/−1″, travelling inside the floor channel—glass is preferably held in place by a clamp secured to the frame; h) recessed base with incorporate spring-loaded dropdown cover concealing the height adjustment mechanism; i) spring-loaded dropdown cover pre-assembled in factory; and j) post and distance channels designed with a radius of about 4″.

[0389] With respect to the “solid panel” embodiment of the present invention, it may have the following the following components, features, dispositions, interrelations, variants and/or resulting advantages, namely: a) solid panels are modular unitized panels with a recessed base; b) solid panels are stackable; c) solid panel frame is steel, with vertical slotting in the post; d) panel to panel connection by clip in steel slotting post; e) slotting in the post will also provide way of hanging of different kinds of accessories (i.e. overheads, work surfaces, furniture, shelving, etc.)—also, this could be achieved horizontally via horizontal track channel; f) shells are clipped or hung with the stiffeners to the frame into steel/spring steel clips which are fastened to the inside of the frame or hung horizontally; g) recessed base with incorporated spring-loaded dropdown cover; h) height adjustment of about +/−1″, traveling inside the floor channel, clamp is screwed to the frame; i) height will be adjusted with a power tool from the side of the panel; j) optional continues horizontal hooking channel incorporated in the frame; k) optional continuous horizontal hooking channel with stackable panels; and l) total width of hooking channel is ⅜″, slot is shaped round to accept a same shape bracket, designed to prevent bracket from falling out.

[0390] With respect to the “height adjustment assembly” embodiment of the present invention, it may have the following components, features, dispositions, interrelations, variants and/or resulting advantages, namely: a) height adjustment of about +/−1″, traveling inside the floor channel, clamp is screwed to the frame or is clamping ⅜″ or ½″ glass; b) height will be adjusted with a power tool from the side of the panel; c) a gear box assembly operates the counter-threaded rod which in turn operates the steel, cross-attached arms which are secured to the glass holding clamps; and d) the height adjustment is accessible from both sides.

[0391] According to the present invention, the wall panel system and corresponding parts are preferably made of substantially rigid materials, such as metallic materials (aluminum, stainless steel, etc.), hardened polymers, composite materials, and/or the like, whereas other components thereof according to the present invention, in order to achieve the resulting advantages briefly discussed herein, may preferably be made of a suitably malleable and resilient material, such as a polymeric material (plastic, rubber, etc.), and/or the like, depending on the particular applications for which the wall panel system and resulting working space are intended for and the different parameters in cause, as apparent to a person skilled in the art.

[0392] As may now also be further appreciated, the wall panel system according to the present invention is an improvement over the prior art in that it provides 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 fast, easy, convenient, proper, systematic and cost-effective manner, thereby avoiding the corresponding drawbacks of the “stick-built” approach of conventional wall panel systems.

[0393] Of course, numerous modifications can be made to the above-described embodiments without departing from the scope of the invention as defined in the appended claims.
