DETAILED DESCRIPTION OF THE EMBODIMENTS
(16) FIG. 1 shows a wall panel 10 comprising a front face 12 and return lips at the top 14 and on the right-hand side 16. The wall panel 10 may also have a return lip at the left-hand side which is not shown in FIG. 1.
(17) FIG. 2 shows a rear view of the wall panel 10. The panel 10 may comprise a return lip 14 at the top and return lips 16, 18 at each side. Each side lip 16, 18 may comprise three mounting clips 20 formed within it. Each of the mounting clips 20 may have an upper locating hole 22 and a lower locating hole 24. Towards the lower part of the wall panel 10 there may be a batten 26, which may provide additional stiffness to the panel 10 and may space the lower part of the panel 10 from the wall in use.
(18) FIG. 3 shows a side view of the wall panel 10 with the return lip 18 visible. Batten 26 is shown in profile, although in practice it may not be visible behind the return lip 18.
(19) FIG. 4 shows a rear view of the wall panel 10, as described with respect to FIG. 2.
(20) FIG. 5 shows a detailed view of the corner VI labelled in FIG. 1 of the wall panel 10. Portions of the front face 12 and return lips at the top 14 and side 16 are shown. The piece of material forming the front face 12 may be formed with one portion bent around to form a flap-like portion at about a right angle to the front face 12 to form the top lip 14, with one portion 16A bent around at about a right angle to the front face 12, and with a further portion 16B bent around so that it lies approximately parallel to the front face 12. Portions 16A and 16B together may form side lip 16. Hole 19 may be provided close to the corner to cater for a pop-rivet or other earth connector, for use in rooms containing RF-generating equipment such as an MRI apparatus. This may allow the panel to be to electrically connected to ground or to a nearby Faraday cage structure, thereby preventing the panel from acting as a capacitor driven by RF energy in the room.
(21) FIG. 6 shows a plan view of the same wall panel 10, with the return lips at the top 14 and side 16.
(22) FIG. 7 shows a detailed view of a mounting clip 30, in relation to certain parts of the panel, in accordance with the embodiments of the present disclosure. The mounting clip 30 may be in the form of a flat tab or tongue, and may be formed from a portion of a return lip which may form a flange as set out above. The plane of the flange may be substantially parallel to the front face 12. Thus, the mounting clip 30 may be spaced apart from the front face 12 of the panel. The mounting clip 30 may have a fixed end 31 and a free end 33. In the region of the free end 33, an end portion 35 may be provided, which lies substantially parallel to the front face 12 of the panel. Between the fixed end 31 of the mounting clip and the free end 33, a series of curves 32A, 32B, 32C may be provided, setting portions of the mounting clip 30 at differing distances from the front face 12 of the panel. The curves may be formed so that the mounting clip 30 may have a local minimum distance D.sub.MIN from the front face 12 of the panel and a local maximum distance D.sub.MAX from the front face 12 of the panel. The local minimum distance D.sub.MIN may be closer to the free end 33 than the local maximum D.sub.MAX may be to the free end 33. A further portion 34 of the return lip may also be shown to show the discontinuity of the mounting clip 30 from the rest of the return lip. The vertical displacement between the free end 33 of the mounting clip 30 and the proximate flange portion 37 of the return lip 34 may be small.
(23) FIG. 8 shows the mounting clip 30 in a position in use with respect to a channel C attached to a wall W. Curves 32A, 32B, 32C may provide for engagement with the channel C at least at the local minimum distance D.sub.MIN. The curves may also provide a spring-like force to urge the mounting clip 30 towards the front face 12 of the panel so as to hold the panel against the wall W. The vertical displacement between the free end 33 of the mounting clip 30 and the proximate flange portion 37 of the return lip 34 may be small. Thus, a portion of the return lip 34 may overlap the material forming the channel C vertically.
(24) FIGS. 9 and 9a show the wall panel 10 attached in place to a wall W. FIG. 9a illustrates an enlarged view of the lower part 38 of the wall panel 10. Channels C may be affixed to the wall W in order to receive the mounting clips 20 and prevent the wall panel 10 from moving away from the wall W. At the lower edge of the wall panel 10, a ledge 40 may be affixed to the wall using a suitable technique such as an adhesive, or wall fixings such as screws secured in wall plugs appropriate to the type of wall W. The lower edge 14 of the wall panel may then rests on the ledge 40 to provide support for the wall panel 10, thereby supporting the weight of the panel 10.
(25) Accordingly, a precise positioning of the mounting clips 20 and the channels C may not be crucial as they do not dictate the vertical alignment of the wall panel 10 or support its weight. As a result, the channels C can be fitted to the wall quickly and easily. It may be relatively straightforward to fit a ledge 40 to a wall at a low and accessible position with a high degree of accuracy, and the same ledge may extend beneath a number of adjacent panels, thus holding all panels at an accurate and consistent height to provide a neat appearance. Once the ledge and channels are in place and the tabs have been formed in the flanges of the wall panels (as described below), paneling the wall may be a quick and simple task. For example paneling the wall may comprise positioning each panel in turn and moving it downwards so that the tabs engage with the channels and the lower edge of the panel rests on the ledge. This arrangement may allow panels to slide horizontally so that they abut one another to provide a continuously paneled surface.
(26) FIGS. 10 to 13 show different views of a device 100 for forming the mounting clip in accordance with the embodiments of the present disclosure. FIGS. 10 to 12 show the device 100 as arranged for use, and FIG. 13 shows the device 100 in exploded form to clearly show how the elements fit together. The device 100 may have a first die element 102 with a raised portion 104 which may be shaped to form a curved profile. The first die element 102 may have locating holes 106 at either end. A second die element 108 may have locating holes 110 at either end which may correspond to the locating holes 106 of the first die element 102. The second die element 108 may form an open-box-like structure—there being an opening on its under-side as shown in the figures. Extending into the space within the second die element 108 from an upper part 112 may be a raised portion 114 which may be shaped to form a curved profile. The profiles of the raised portion 104 of the first die element 102 and the raised profile 114 of the second die element 108 may correspond with each other and form corresponding first and second faces for defining a desired shape for a clip. The device 100 may have a pair of pulleys 116 linked by a belt 120. The pulleys 116 have drive holes 118 formed within them which correspond to the locating holes 106 and 110 of the first 102 and second 108 die elements, respectively. The device 100 may further comprise a cover 122 with walls 124 which may enclose the second die element 108 in use. The cover 122 may have locating holes 126 on at least one side, which may correspond to locating holes 128 on at least one side of the second die element 108. When assembled for use, the device 100 may have rods 130, 132 arranged through the locating holes 106, 110 and drive holes 118 of the first 102 and second 108 die elements and the pulleys 116, respectively. The rods 130, 132 may each be provided with a screw thread on the outside surface. The screwthread of rod 130 may be engageable with a corresponding screwthread on the inside surface of locating hole 134 of the cover 122 and with locating hole 106 of the first die element 102. Thus, a drawing mechanism may be provided in which the first die element 102 and the second die element 108 can be drawn together by rotation of rod 130. Rod 132 may engage with a corresponding screwthread in the corresponding locating hole 106 of the first die element 102. Thus, when rod 130 is rotated a drive force may be transmitted between pulleys 116 by belt 120 so that rod 132 is rotated as a slave member. This action may allow for a balanced draw to be exerted on the punch driven from only a single torque input. Washers 136, 138 may be positioned on rods 130, 132 between the second die element 108 and the spacers 116. Grubs 140 may be affixed to an under-side of the locating holes 106 of the first die element 102.
(27) Thus, assembled for use, the cover 122, spacers 116 and second die element 108 may be held together with respect to one another by the rods 130, 132 and suitable locators
