(54) IMPROVEMENTS RELATING TO WALL SIDING PANELS (71) We, ABITIBI-PRICE INC, formerly ABITIBI PAPER COMPANY LIMITED, of Toronto-Dominion Centre, Toronto 111, Ontario, Canada, a Canadian company do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed to be particularly described in and by the following statement: This invention relates to securing of wall siding panels.

It has been common practice for many years to attach siding panels to the walls of houses and other buildings, and the siding panels have been attached to the walls in many different ways. Siding panels should be attachable in a simple, efficient and secure manner, and the attachment should be long-lasting and able to withstand a variety of weather conditions.

It is, therefore, an object of the invention to provide an improved manner of attaching siding panels to walls.

According to the invention, in a first aspect, a wall siding panel assembly includes a siding panel having a front face and a generally-flat rear face, the panel having a bottom edge and adjacent thereto a recess in the rear face, parallel to but spaced from the said bottom edge, and a fastener having a substantially rigid strip-like body extending backwards from the recess and including a forward portion which is located in the recess and which has a rigid rib projecting from and extending along a lower face of the body in the said forward portion so as to retain the fastener in the recess.

Preferably the fastener body has an upper face substantially parallel to the said lower face thereof, both said faces being substantially plane, the recess being inclined upwardly from the rear face of the panel so that the fastener body extends away from the panel in a downward inclination.

The fastener preferably includes a rigid projection extending generally downwards from and along a rear portion of the said lower face remote from the said forward portion, the said rigid projection being spaced from the rear face of the panel.

The fastener is preferably of synthetic plastics material, for example rigid polystyrene.

According to the invention, in a second aspect, a wall siding installation comprises a wall, a plurality of wall siding panel assemblies according to the said first aspect of the invention and secured to the wall, the panel of each panel assembly having a top edge extending in a direction parallel to its bottom edge, and the fastener of at least one said assembly resting on the top edge of the panel of another said assembly below it, so that the panels lie generally one above the other in overlapping relationship.

Preferably at least one said panel is secured to the wall by at least one nail through the panel behind the overlapping portion of a said panel next above it, the or each nail having its head proud of the panel secured thereby so as to provide a ventilation gap between the overlapping panels.

The installation preferably includes at least one clip having a back portion secured to the wall and means joined to the back portion and defining a downwardly-facing, generally U-shaped channel, the upper edge of a said panel being disposed within said downwardly-facing channel so as to secure the said panel to the wall.

Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, of which: Figure 1 is a side view, partly in section, of a sliding panel with attached fastener; Figure 2 is a side view of the fastener; Figure 3 is a perspective view of an upper panel with fastener mounted on a lower panel; Figure 4 is a side view, partly in section, of a siding installation; Figure 5 is a side view of a lower-most panel and starting strip; Figure 6 is a side view of a siding installation according to a further embodiment; and Figure 7 is a side view of the clip used in the installation of Figure 6.

Referring to Figures 1 and 2, a wall sliding panel 18 is assembled with a fastener 11 to form a wall siding panel assembly. The panel 18, of which only a lower portion is shown in Figure 1, is of a suitable fibreboard substrate and has a front face 19 and a generally-flat rear face 20. Adjacent the bottom edge of the panel, and parallel to but spaced from the bottom edge, is a recess 21 in the rear of face 20.

The fastener 11 has a substantially rigid strip-like body 12 extending backwards from the recess 21. For consistency with the designation of the panel faces 19, 20 as front and rear faces respectively, terms such as "forward" and "rear" and similar words are used herein to indicate parts of the fastener towards the left and right hand sides respectively of Figures 1 and 2. Thus the fastener body 12 includes a forward portion which is located in the recess 21 and which has a pair of ribs 13. 14. projecting from and extending along the plane lower face of the said forward portion of the fastener body. The ribs 13, 14, are spaced apart parallel to each other. the rib 13 being located adjacent the forward end of the body 12 and the rib 14 behind the rib 13. Each rib 13, 14 is substantially triangular in cross-section. and is inclined to the body by an obtuse angle forward of the rib.The ribs 13. 14 retain the fastener in the recess 21.

The body 12 has a plane upper face substantially parallel to its lower face, and the recess 21 is correspondingly substantially rectangular in cross-section with an upper wall 22. lower wall 23 and side wall 24. The recess is inclined upwardly from the panel rear face 20. Adjacent the rear face 20 but externallv of the panel. the body 12 has a series of holes 17 spaced along it.

Extending vertically downwards from.

and along. a rear portion of the lower face of the fastener body 12 is an integral rigid projection 16.

The fastener 11. including ribs 13. 14. is an extrusion of rigid polvstvrene.

The fastener 11 is assembled with the panel 18 by forcing the forward end portion of the fastener into the recess 21. until the forward end of the body 12 engages the side wall 24 as seen in Figure 1. The ribs 13. 14 are engaged by the lower wall 23 of the recess 21. and force the upper surface of the body 12 against the upper wall 22 of the recess. If desired. a suitable adhesive may be placed in the recess 21 before the fastener 11 is inserted, so as more securely to retain the fastener therein. The forward end portion of the body 12 then projects from the recess 21 in a downwardly inclined direction, the projection 16, being parallel to and spaced from the rear face 20 of the panel 18, and with the holes 17 being located externally of the panel but near the rear face 20.

Referring now to Figures 3 and 4. the upper end of each panel 18 of a wall siding installation has a rear portion cut away in the form of a rebate to provide an upper rear surface 25 spaced from the front face 19 by a distance slightly less than the distance between the rear face 20 of another panel 18, adjacent the said front face 19 and overlapping it, and the downwardlyextending rigid projection 16 of a fastener 11 secured in the rear face of the said other panel 18. The upper edge 26 of the panel 18 between the front surface 19 and the upper rear surface 25 slopes downwardly from front to rear at the same angle as the body 12 extends from the panel 18. The bottom surface 27 of the rebate between the upper rear surface 25 and the main rear surface 20 slopes downwardly at the same angle.

To install a pluralitv of panels 18 with attached fasteners 11 in a siding installation including a wall 28 to which the panel assemblies are secured. a pariel 18 is positioned on top of a lower panel 18. previously secured to the wall 28. by positioning the fastener body 12 over the upper end of the lower panel 18, so that the body 12 rests on the upper edge 26 and the downwardly extending projection 16 lies in the rebate behind the upper rear surface 25. as shown in Figure 4. The upper portion of the upper panel is then secured to the wall 28 bv at least one. but preferably a series of nails 29 extending horizontally, so as to be covered by the following upper row of panels. but clear of the fastener 11.

It will be noted that the fastener 11 is assembled with the panel 18 without having to penetrate any previously painted panel surface. thus avoiding the likelihood of paint failure after exposure to weather which results if a painted surface is ruptured. Also. the fastener 11 can accommodate misalignment such as can occur when a wall is not perfectly straight or the siding courses are not exactly level. Adequate ventilation is also provided by the holes 17.

and bv the gap between the rear surface 20 of an upper panel and the front surface 19 of a lower panel maintained bv the presence of the head 30 of the nail 29.

Figure 5 shows an aluminium starter strip 31 for the bottom course. The strip 31 has a main portion 32 secured to the wall 28. a U-shaped bottom portion 33 and a terminal portion 34 sloping at the same angle as the; upper edge of a panel. The bottom of the, U-shaped portion 33 has holes 35 for ventilation purposes.

Figure 6 shows a modified installation in which the use of nails 29 passing through the panels 18 is avoided by use of clips 36 by which each panel is secured to the wall and one of which is shown in side view in Figure 7.

The clip 36 is also an extrusion of synthetic plastics material, with a relatively high back portion 37 which has a series of longitudinally spaced apertures 38 near its upper end. At the lower end, the clip 36 has an upwardly facing, generally U-shaped channel portion 39 having one wall extended to define the back portion 37, and another wall which terminates in a downwardly-facing, generally L-shaped portion 40 extending from the top of the upwardly facing channel portion 39: The downwardly extending L-shaped portion 40 is somewhat thinner, and therefore more resilient, than the remainder of the clip 36. and defines a downwardly facing generally U-shaped channel.

When installing one panel 18 above another. the upper portion of the lower panel 18 is not nailed to the wall 28 as in the previous embodiment. but a clip 36 is mounted over the upper edge by positioning the downwardly facing L-shaped portion 40 over the forward upper end portion of the panel. so that the upwardly facing channel portion 39 lies between the upper rear surface 25 of the panel 18 and the wall 28.

The back portion 37 of the clip is then nailed to the wall 28 by nails 41 passing through the apertures 38.

An upper panel 18 is then positioned on top of the lower panel by positioning the body 12 of the fastener 11. secured in the upper panel. over the downwardly facing L-shaped portion 40. so that the downward ly extending portion 16 of the fastener 11 lies within the upwardly facing channel portion 39. at least part of which lies in the rebate of the lower panel.

The main advantage of using clips 36 is that the panels themselves do not have to be nailed to the wall. and instead are held at top and bottom in such a manner as to be capable of a certain amount of expansion and contraction. thus reducing the likelihood of buckling of the panels. Also. more air circulation is possible since the upper panel is spaced from the lower panel bv the thickness of the foremost arm of the Lshaped portion 40. and the lower portion can be spaced from the wall 28 by appropriate dimensioninp of the channel portion 39.

The bottom of the, U-shaped portion 33 has holes 35 for ventilation purposes. Figure 6 shows a modified installation in which the use of nails 29 passing through the panels 18 is avoided by use of clips 36 by which each panel is secured to the wall and one of which is shown in side view in Figure 7. The clip 36 is also an extrusion of synthetic plastics material, with a relatively high back portion 37 which has a series of longitudinally spaced apertures 38 near its upper end. At the lower end, the clip 36 has an upwardly facing, generally U-shaped channel portion 39 having one wall extended to define the back portion 37, and another wall which terminates in a downwardly-facing, generally L-shaped portion 40 extending from the top of the upwardly facing channel portion 39: The downwardly extending L-shaped portion 40 is somewhat thinner, and therefore more resilient, than the remainder of the clip 36. and defines a downwardly facing generally U-shaped channel. When installing one panel 18 above another. the upper portion of the lower panel 18 is not nailed to the wall 28 as in the previous embodiment. but a clip 36 is mounted over the upper edge by positioning the downwardly facing L-shaped portion 40 over the forward upper end portion of the panel. so that the upwardly facing channel portion 39 lies between the upper rear surface 25 of the panel 18 and the wall 28. The back portion 37 of the clip is then nailed to the wall 28 by nails 41 passing through the apertures 38. An upper panel 18 is then positioned on top of the lower panel by positioning the body 12 of the fastener 11. secured in the upper panel. over the downwardly facing L-shaped portion 40. so that the downward ly extending portion 16 of the fastener 11 lies within the upwardly facing channel portion 39. at least part of which lies in the rebate of the lower panel. The main advantage of using clips 36 is that the panels themselves do not have to be nailed to the wall. and instead are held at top and bottom in such a manner as to be capable of a certain amount of expansion and contraction. thus reducing the likelihood of buckling of the panels. Also. more air circulation is possible since the upper panel is spaced from the lower panel bv the thickness of the foremost arm of the Lshaped portion 40. and the lower portion can be spaced from the wall 28 by appropriate dimensioninp of the channel portion 39.
