Cl. 52-212 9 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION This invention relates to partition walls and to trim elements for such walls. The invention is particularly concerned with a demountable partition wall of the kind comprising an assembly of panels supported by a frame structure to which they are secured by metal retaining strips or battens which also conceal the edges of the panels and form a trim; the metal retaining strips are fastened by means of screws, for example, to the frame structure and the fastenings are concealed by cover strips whose appearance may contrast with that of the retaining strips and give the wall a decorative appearance. The frame structure normally comprises upper and lower horizontal frame members and vertical frame members or studs extending between the horizontal members, and panels being mounted on both sides of the structure and the retaining strips being fastened to the studs.
Known wall structures of this kind suffer from certain disadvantages. In the first place owing to small variations in floor level or ceiling level in a building, the studs or vertical frame members need to be cut to slightly different lengths to suit such variations; consequently, if the wall is to be demounted and erected in a different position the studs cannot readily be used again. The skirtings of the walls are frequently of untidy appearance because of variations in floor level. Another disadvantage is that the method of retaining the cover strips in the retaining members, while permitting of a decorative appearance over much of the trim, necessarily gives rise to discontinuities in the trim at all points where vertical and horizontal trim elements meet, and these discontinuities, which are aggravated when inserts such as doors and windows are built into the wall, spoil the general appearance of the wall. Yet another disadvantage is that the cover strips, which are generally retained in longitudinal channels on the front faces of the retaining strips and held in place by inwardly turned lips at the mouths of the channels, are frequently damaged when they are removed from the channels so that they become unsuitable for further use.
SUMMARY OF THE INVENTION The present invention provides a demountable partition wall construction which is substantially free from the above-mentioned disadvantages.
In accordance with the present invention the trim elements comprise metal retaining strips each formed on its front face with a longitudinally extending rib formation, and resilient cover strips of channel section adapted to be snapped over the rib formations of the retaining strips and frictionally retained thereby. In use in a partition wall according to the invention, the metal retaining strips are arranged vertically and horizontally to conceal the edges of the panels, the upper and lower ends of the vertical retaining strips abutting against the horizontal retaining strips, and the ends of the vertical cover strips extend beyond the ends of the retaining members on which they are mounted into abutting relation with the horizontal cover strips. In this way discontinuities in the trim where the vertical and horizontal trim elements meet, are avoided.
In order to provide a skirting, the lowest of the horizontal retaining strips is disposed adjacent to the bottom edge of the walls, i.e. about four inches from the floor, and the cover strip thereof is formed with an integral flange which extends downwardly into close proximity with the floor. Preferably, the bottom edge of the panel assembly is concealed by an upstanding flange having an appearance matching that of the downwardly extending flange, and the upper edge of the upstanding flange is concealed by the downwardly extending flange, which laps over it.
The retaining strips are preferably of extruded aluminum and the cover strips may be of vinyl plastic or other elastomeric material, but it will be obvious that many other materials may be used for these components. The rib formation on the front face of a retaining strip may simply take the form of a step whose side edges are adapted to engage the inside surfaces of the side walls of a channel shaped cover strip, the retaining strip being provided with screw holes which are countersunk to receive the heads of the screws. In a preferred construction, however, the rib formation is formed by a pair of longitudinal, parallel upstanding lips whose outer surfaces engage the cover strip and whose inner surfaces define a channel in which the heads of the screws are located.
BRIEF DESCRIPTION OF THE DRAWINGS A specific embodiment of the invention will now be described in detail with reference to the accompanying drawings, which illustrate by way of example features of a particular demountable partition wall construction.
In the drawings:
FIG. 1 is a front elevation of a portion of the wall, the figure illustrating the general pattern of the trim on one side of the wall;
FIG. 2 is an enlarged, fragmentary, perspective view of a detail of the wall, the figure particularly showing a joint between vertical and horizontal trim elements, and the form of the skirting;
FIG. 3 is an enlarged, fragmentary, perspective view of a detail at the top of the wall;
FIG. 4 is a cross sectional view of a retaining strip and cover strip; and
FIG. 5 is an enlarged, fragmentary, perspective view of a detail of the wall adjacent to a window.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, the wall basically comprises an assembly of panels 1, for example plaster board panels, which are secured to a frame structure and supported thereby, the frame structure being composed of vertical steel frame members or studs 2 spaced at regular intervals and extending between channel shaped, upper and lower, horizontal, steel frame members 3 and 4. Frame structures of this type are known, and it will be understood that the frame members may be of other forms than the particular ones illustrated. A similar assembly of panels 5 is mounted on the opposite side of the frame structure, the panel assemblies being spaced. The space between the panel assemblies may be filled with sound absorbing material. Each panel 1 and 5 is rectangular, having horizontal upper and lower edges 6 and vertical side edges 7 (FIGS. 2 and 3). As shown in FIG. 1, the panels 1 (the panels 5 being similarly arranged), extend across the entire height of the wall from the floor 8 to the ceiling 9, although small gaps will in practice be left beneath the bottom edge and above the top edge of the panels on account of small irregularities in floor and ceiling level; these gaps are concealed by a skirting 10 and border strip 11, which will be described in greater detail hereinafter. FIG. 1 also shows a metal framed window 12 extending the full height of the wall, and a door 13, above which is a small panel 14.
The edges of the panels are concealed by trim elements, the basic form of which is shown in cross section in FIG. 4. Referring to FIG. 4, a trim element comprises a retaining strip or batten 15 and a cooperating resilient cover strip 16. The retaining strip 15 is an aluminum extrusion of uniform section having a front face formed with a rib formation consisting of a pair of parallel, longitudinal lips 18, a pair of longitudinal edge flanges 19, and a rear face formed with slightly raised ridges 20 at its edges and a raised central a'rea 21 which is coplanar with the tips of the ridges 20. The outer edges of the lips 18 are chamfered as shown at 22, and are provided with grooves 23. The cover strip 16 is a channelsectioned extrusion of vinyl plastic, having a pair of side walls 24 provided with inwardly directed longitudinal ribs 25 which are adapted to engage in the grooves 23 so that the cover strip is frictionally retained by the retaining strip. In assembling, the cover strip is simply snapped over the lips 18 as shown in ghost lines in FIG. 4.
Although the basic forms of the retaining strips and cover strips are shown in FIG. 4, these forms are modified to adapt them to particular parts of the trim assembly. Thus, the trim elements 26 shown in FIG. 1 are exactly as described with reference to FIG. 4. On the other hand, trim elements 27, 28, 29 and 30 adjacent to a window 12, and trim elements 31, 32 and 33 adjacent to a door 13, are modified in that the retaining strips are replaced by frame members of the window and the door. This modified construction is illustrated in FIG. 5 and will be described with reference to that figure. Furthermore, the trim elements 34 and 35 adjacent the bottom and top edges of the wall, and the trim elements at the ends of the wall, not shown, are modified to the extent that the cover strip is formed with an integral flange at one side which extends substantially to the peripheral edge of the panel assembly. Such modifications are illustrated in FIGS. 2 and 3.
Referring now particularly to FIGS. 2 and 3, the trim element 26 of FIG. 1 comprises a vertical retaining strip 36 extending along and overlapping the abutting vertical edges 7 of the panels 1 so as to conceal these edges. The strip 36 is provided with screw holes at intervals to receive screws 37 which fasten the retaining strip to the frame member 2 and batten the panels 1 to it. A cover strip 38 is snapped on to the retaining strip. The trim elements 34 and 35 of FIG. 1 also comprise retaining strips 39, 40 of the form shown in FIG. 4, and are secured to the vertical frame members 2 by screws 37. The upper and lower ends of the vertical retaining strip abut against the lower and upper edges, respectively, of the retaining strips 40 and 39. The retaining strips 39 and 40 are provided with snap-on cover strips 41, 42, and the cover strip 38 extends beyond the ends of the retaining strip 36 into abutting relation with these cover strips 41 and 42.
As illustrated in FIG. 2, the bottom edge of the wall is concealed by an upstanding vertical flange 43. This flange is of the same material as the vinyl cover strips, or may be painted or treated to give it an appearance matching that of the vinyl cover strips. The horizontal retaining strip 39 is positioned adjacent to the floor 8, and the cover strip 41 thereon is formed with an integral flange 44 which extends downwardly into close proximity with the floor so as to conceal the upper edge of the flange 43 and form the skirting 10 of FIG. 1.
FIG. 3 shows the upper end of the vertical retaining strip 36, which butts against the horizontal retaining strip 40, and the cover strip 38 which butts against the cover strip 42. The cover strip 42 is formed at its upper edge with an integral, upwardly extending flange 45 which conceals the upper edge of the panel assembly and forms the border strip 11 of FIG. 1. The vertical retaining strips at the ends of the wall face, not shown, are provided with cover strips similar to the strip 42, having outwardly directed flanges which conceal the peripheral edges of the panel assembly.
It will be noted that each panel is in this way framed by a rectangular arrangement of trim elements, each panel being bordered by a continuous metallic surface with a continuous vinyl plastic surround; there are no free ends or visible discontinuities in the trim.
As previously mentioned, the window 12 and door 13 are eachprovided with a metallic frame, the frame members of which each have a front face which is identical in profile with that of the retaining strip 15 of FIG. 4. In order to provide continuity in the trim, these retaining strips are aligned with and continue the lines of trim elements such as 34 and 35, with which they share common cover strips. Details of such construction are shown in FIG. 5.
Referring to FIG. 5, the window 12 is located with its edges in a continuous channel 47 in a flanged aluminum frame 48, the window being gripped by vinyl strips 49 keyed onto lips 50 of the frame which project across the mouth of the channel 47. The portions of two front flanges 27' and 30 at one corner of the frame 48 are shown. The front faces of the flanges 27' and 30 are identical with that of the strip 15 of FIG. 5, and the window frame 48 is positioned at a height such that the flange 30' meets the end of the retaining strip 39 and forms in effect an extension of it. The other end of the flange 30' meets and is aligned with another retaining strip similar to 39. The cover strip 41 extending along the retaining strip 39 is also snapped onto the rib formation 18' of the flange 30 and extends continuously from one end of the Wall to the other. The downwardly extending flange 44 of the cover strip 41 forms a continuous skirting. The frame member of flange 27' also has a front face identical with that of a retaining strip, and effectively abuts against the flange 30 at its end, the cover strip 38' extending beyond the end of the flange 27' into abutting relation with the cover strip 41.
The upper frame member 29 of the window is similarly disposed with respect to the trim element 35, sharing a common cover strip with it. The other vertical frame member of the window is adapted to provide a trim element 28 in exactly the same manner as the frame member 27'. The door 13 has a flanged metal frame in three parts, which may be assembled after the partition wall has been built. The upright frame members, which extend to the ground, and the horizontal frame member, of the door, have front flanges formed with the same profile as the retaining strips, and are provided with cover strips to form trim elements which are continuous with the other trim elements in the manner already described.
It will be observed that the general appearance of the wall face is attractive because of the continuity of the trim everywhere. The construction is also well adapted for dismantling and re-erecting, because the cover strips can easily be removed without damage, and because vertical frame members of uniform height may be used notwithstanding variations in floor level and ceiling level. The upper and lower horizontal retaining strips are set at respective nominal distances from the floor, and any variations of level of the upper and lower edges of the panel assembly are masked by the provision of the flanged cover strips forming the skirting and the border strip.
Referring again to FIG. 2, it will be appreciated that the flanged members 43 will be secured in position by suitable means (not shown). Preferably the horizontal flanges will be extended beneath the channel-sectioned frame member 4 and clamped between the member 4 and the floor, in a manner similar to that illustrated in FIG. 5. The member 4 is secured to the floor by fixing screws (not shown) passing through its base.
