Description
1~99~173 This invention relates to construction panels of the type used to build up siding and so~fits on building structures.
The term "siding'! will be used in the following description to include wall coverings, soffits and the like which are made up from panels which inter-lock with one another at longitudinal marginal portions of the panels. Different visual effects can be obtained by varying the profile, texture and finish of the front surfaces of the panels and in some instances the panels would be perforated to provide ventilation.
In general, siding falls into two types.
In a first type the front surfaces of the panels lie substant-ially in a common plane whereas in a second type a forward part of a marginal portion is exposed giving the siding the appearance of more traditional wood clapboard siding. For the purposes of the present description the first type will -be termed "flush siding" and the second type "lap siding".
` Construction panels for use in assembling siding are usually of roll formed sheet steel or aluminum construction with painted or coated finishes. However, plastic panels are also available. In general,-construction panels of these types are provided both with interlocking arrangements along marginal portions and with structure to permit each panel to be nailed or otherwise attached to a building structure. On assembly a panel is generally first secured on the building using a starter strip and then attached at one of its marginal portions. The next panel is then engaged ~k ~9ai ,~3 in this one marginal portion and this next panel is also attached to the buil(3ing structure by its ~?xposed o~her marginal portion. The procedure is repeated from panel to pane7 until the sidinq is completed.
In pr-ior art p-~nels, the interlock provided along one marginal portion of a construction panel has a different s'nape from that provided at the other marginal portion. ~onsequently, once siding has been started, each added panel has a right way up. This can prove to be a disadvantage, particularly if long panels are being assembled in a limited space where it may prove to he extremely inconvenient to have to turn and invert the panel to continue assembly. ~lso, if it is necessary to cut a panel longitudinally or to mal~e an angle cut when applying panels to a gable end it is unlikely that the offcut would prove to be u.seful. There can therefore be considerable wastage in some installations. A further disadvantage of prior art panels is that they must be applied working from one side only. This can be a disadvantage particularly in soffit installations and when installing vertical siding on gable ends where symmetry is desirable. Also when commencing from the bottom of a wall it is necessary to use a special starter strip.
The present invention provides an elongated construction panel having a substantially constant cross-section and including a main portion having a front face which is exposed on assembly of the panel on a building. The main portion has transverse extremities and similar first and second marginal portions are dependent from the respective transverse extremities of the main portion, and extend longitudinally of ; the panel. These portions are mirror images of one another and they also extend generally rearwardly with respect to the main : '' , ~ ':
~9~73 portion of the panel. Each of said marginal portions defines engagement means such that the engagement means of the panel are engageable with other engagement means of another panel in a position in which the main portion and the main portion of the other panel are spaced generally parallel with one another. The marginal portions include similar short portions lying generally parallel to the main portion for engagement in overlying relationship with the main portion of the other panel such that the panel and the other panel are in the aforementioned - 10 position. Also the first and second marginal portions both define means adapted to attach the panel to a wall.
- The invention will be better understood with reference to the drawings, in which:
Fig. 1 is an end view of construction panels on a wall and showing an assembly both in the lap condition and in the flush condition;
Fig. 2 is a view similar to Fig. 1 and showing another embodiment of construction panel which is also for use where both flush and lap requirements may be encountered;
Fig. 3 illustrates a further embodiment suitable for use in both lap and flush conditions and including a spacer or filler in the flush condition; and Fig. 4 illustrates yet another embodiment of construction panels according to the invention.
Before describing the embodiments shown in the drawings in detail, it should be noted that the panels have no "right way up" and can therefore be installed from one marginal portion or the other. This is particularly advantageous where a panel is being attached horizontally because if an installer takes the panel to the building structure he does not have to worry about whether or not it is upside down. In many instances the space between buildings would make it difficult to turn and invert a long panel and consequently this structure has a major advantage in this respect. Also the panel allows an installer to start anywhere and to work away from the first panel in both directions when installing flush siding.
,~
10~9~73 Reference is now made to Fig. 1 which illustrates a panel 10 which is coupled at its upper extremity to a lower part of a panel 10' in a lapped condition and at its lower extremity to a panel 10" in a flush condition. Parts of panels 10' and 10" will be given respective primed and double primed numerals where they correspond with parts of panel 10. Similarly, because the marginal portions of the panels are similar, they will be differentiated by the suffix "a" for a top marginal portion as drawn and by the suffix "b" for a bottom marginal portion as drawn. This system will also be used in the other Figs.
The panel 10 includes an outer channel 12a located between an inner channel 14a and a main portion 16 of the panel 10. Outer channel 12a is deeper than channel 14a to accommodate a tongue 18b' and to cause inter-engagement with channel 14b'. When this panel 10' is lapped relative to panel 10 a part of a front wall of channel 14b' is in face-to-face engagement with a part of the front face of main portion 16 of panel 10. Consequently if for any reason the engagement between these panels is not complete, the appearance presented will not be affected.
At the lower portion of Fig. 1 an interlock between panels 10 and 10" is shown. As seen in this figure the panels include deformations in the tongue 18a"
and channel 14b for a degree of locking engagement. Channels 12b etc. are also shaped to accommodate this locking engagement.
Such an engag~ment is of course optional. It should also be noted that each of the channels 14a etc. are closed at their mouths to enhance the flush appearance in the flush condition. This is achieved because the result is to displace ~)99~73 both main portions 16 and 16" away from the building by the thickness of a tongue.
In the lapped condition shown in Fig. 1, the channel 12b' is evident after assembly and may be considered to detract from the overall lapped appearance.
However this appearance can be improved by forming channels 12b' (and 12a) with a closed mouth like channel 14a.
An improvement over the Fig. 1 structure is shown in the embodiment illustrated in Fig. 2. This embodiment could be preferred where a panel is required both for overlap and flush conditions although in some instances the Fig. 3 panel may be preferred as will be explained.
For simplicity of description of Fig. 2 the numerals used with reference to Fig. 1 will ~e raised by one hundred where they correspond generally to those described with reference to Fig. 1. In Fig. 2 a panel 110 is interlocked with a panel 110' in the overlap condition and with a panel 110" in the flush condition.
Panel 110 includes a marginal portion having a land 20a which extends rearwardly terminating at a dou'ole channel section 22a defining a forward channel 24a and a shallower rearward channel 26a. The channel 24a is defined by a front wall 28a lying parallel to a main portion of the panel and an inclined rear wall 30a which extends to a point inwardly of the land 20a and meets a forward wall 32a of rearward channel 26a. This last wall is also parallel to the main portion of the panel and parallel to a rearward wall 34a which is extended outwardly to form a tongue 36a for attach-ment to the building.
11;999G~73 The lapped interengagement between panel 110 and panel 110' is effected by engaging tongue 36b' in channel 24a so that the land 20a is contained in channel section 22b'. Panel 110' is located against out-ward movement by the tongue 36b' engaging wall 28a and inward movement is prevented by engagement of wall 28b' with the main portion of panel 110. The result is a positive connection giving the assembly an enhanced appear-ance. In the flush condition as illustrated by the inter-engagement of panel 110 and 110" the tongue 36b of panel 110 is engaged in channel 26a" and the walls of this channel prevent forward and rearward movement of panel 110.
The channels 26a etc. may also be closed to enhance the flush appearance after assembly in this condition in the manner of the channel 14a shown in Fig. 1.
The contour of the double channel section 22a described with reference to Fig. 2 can be simplified if a spacer or filler is used as illustrated in Fig. 3 and consequently this Fig. 3 embodiment may be preferred. This simplified contour requires a spacer strip or snorter spacer sections to positively locate the channels in the flush condition. Numerals indicating parts of the Fig. 3 embodiment corresponding to these described with reference to Fig. 1 will be raised by two hundred and by one hundred where they correspond to parts of the Fig. 2 embodiment.
A comparison of Figs. 2 and 3 will indicate that in the overlap position the relationship between the panels 110 and 110' is similar to that between the panels 210 and 210'. The panel 210 defines a single channel 38a having respective front and rear walls 40a, 42a and this - 1099C~73 rear wall extends into tongue 136a. Front wall 40a combines with the interengagement of land 120a in channel 38b' to locate panel 210' in the lapped condition. However, in the flush condition the panel 210 would not be located positively relative to the panel 210" without the use of a spacer or filler 44 which engages in adjacent channels between the panels thereby preventing outward movement of the panel 210 relative to the panel 210". The filler can be either a continuous strip or short pieces located at intervals along the panels and is preferably of a resilient material which will not deteriorate quickly.
With proper proportioning the strip or filler will be a snug fit and tend to limit rattling noises and expansion creaking in the panels.
Further, if the strip is a close fit in channel 38a etc., then in the flush condition shown, the channel 38a" will be spread by the thickness of the tongue contained in the channel thereby making the front faces of adjacent panels coplanar.
Reference is finally made to Fig. 4 which illustrates an embodiment which would be preferable for use where only a lapped effect is desired. A first panel 310 is inter-engaged at a first marginal portion with a second panel 310' and at a second marginal portion with a third panel 310". The inter-engagement is similar to that used for the Fig. 3 embodiment but the panel 310 lacks structure necessary for inter-engagement in the flush condition. For ease of comparison parts correspond-ing generally with those described with reference to Fig. 3 will be given similar numerals but raised by one ~0~9~73 hundred. Such comparison will also show that this embodiment can be made for use in both lap and flush conditions by extending the flange.
- Although many variations can be made to the shape of the marginal portions described with reference to the previous embodiments, the principle explained with reference to these structures should be maintained for adequate results. It will also be appreciated that changes can be made to alter the appearance. For instance the main portion of the panel could be formed or textured to change the overall appearance of the siding and also with suitable modification a trim or ventilating strip could be inserted between adjacent panels. This is particularly evident in the Fig. 3 embodiment in which the spacer or filler 44 could have an extension projecting between adjacent panels if such a trim strip is desired.

10~9~73 Reference is now made to Fig. 1 which illustrates a panel 10 which is coupled at its upper extremity to a lower part of a panel 10' in a lapped condition and at its lower extremity to a panel 10" in a flush condition. Parts of panels 10' and 10" will be given respective primed and double primed numerals where they correspond with parts of panel 10. Similarly, because the marginal portions of the panels are similar, they will be differentiated by the suffix "a" for a top marginal portion as drawn and by the suffix "b" for a bottom marginal portion as drawn. This system will also be used in the other Figs.
The panel 10 includes an outer channel 12a located between an inner channel 14a and a main portion 16 of the panel 10. Outer channel 12a is deeper than channel 14a to accommodate a tongue 18b' and to cause inter-engagement with channel 14b'. When this panel 10' is lapped relative to panel 10 a part of a front wall of channel 14b' is in face-to-face engagement with a part of the front face of main portion 16 of panel 10. Consequently if for any reason the engagement between these panels is not complete, the appearance presented will not be affected.
At the lower portion of Fig. 1 an interlock between panels 10 and 10" is shown. As seen in this figure the panels include deformations in the tongue 18a"
and channel 14b for a degree of locking engagement. Channels 12b etc. are also shaped to accommodate this locking engagement.
Such an engag~ment is of course optional. It should also be noted that each of the channels 14a etc. are closed at their mouths to enhance the flush appearance in the flush condition. This is achieved because the result is to displace ~)99~73 both main portions 16 and 16" away from the building by the thickness of a tongue.
In the lapped condition shown in Fig. 1, the channel 12b' is evident after assembly and may be considered to detract from the overall lapped appearance.
However this appearance can be improved by forming channels 12b' (and 12a) with a closed mouth like channel 14a.
An improvement over the Fig. 1 structure is shown in the embodiment illustrated in Fig. 2. This embodiment could be preferred where a panel is required both for overlap and flush conditions although in some instances the Fig. 3 panel may be preferred as will be explained.
For simplicity of description of Fig. 2 the numerals used with reference to Fig. 1 will ~e raised by one hundred where they correspond generally to those described with reference to Fig. 1. In Fig. 2 a panel 110 is interlocked with a panel 110' in the overlap condition and with a panel 110" in the flush condition.
Panel 110 includes a marginal portion having a land 20a which extends rearwardly terminating at a dou'ole channel section 22a defining a forward channel 24a and a shallower rearward channel 26a. The channel 24a is defined by a front wall 28a lying parallel to a main portion of the panel and an inclined rear wall 30a which extends to a point inwardly of the land 20a and meets a forward wall 32a of rearward channel 26a. This last wall is also parallel to the main portion of the panel and parallel to a rearward wall 34a which is extended outwardly to form a tongue 36a for attach-ment to the building.
11;999G~73 The lapped interengagement between panel 110 and panel 110' is effected by engaging tongue 36b' in channel 24a so that the land 20a is contained in channel section 22b'. Panel 110' is located against out-ward movement by the tongue 36b' engaging wall 28a and inward movement is prevented by engagement of wall 28b' with the main portion of panel 110. The result is a positive connection giving the assembly an enhanced appear-ance. In the flush condition as illustrated by the inter-engagement of panel 110 and 110" the tongue 36b of panel 110 is engaged in channel 26a" and the walls of this channel prevent forward and rearward movement of panel 110.
The channels 26a etc. may also be closed to enhance the flush appearance after assembly in this condition in the manner of the channel 14a shown in Fig. 1.
The contour of the double channel section 22a described with reference to Fig. 2 can be simplified if a spacer or filler is used as illustrated in Fig. 3 and consequently this Fig. 3 embodiment may be preferred. This simplified contour requires a spacer strip or snorter spacer sections to positively locate the channels in the flush condition. Numerals indicating parts of the Fig. 3 embodiment corresponding to these described with reference to Fig. 1 will be raised by two hundred and by one hundred where they correspond to parts of the Fig. 2 embodiment.
A comparison of Figs. 2 and 3 will indicate that in the overlap position the relationship between the panels 110 and 110' is similar to that between the panels 210 and 210'. The panel 210 defines a single channel 38a having respective front and rear walls 40a, 42a and this - 1099C~73 rear wall extends into tongue 136a. Front wall 40a combines with the interengagement of land 120a in channel 38b' to locate panel 210' in the lapped condition. However, in the flush condition the panel 210 would not be located positively relative to the panel 210" without the use of a spacer or filler 44 which engages in adjacent channels between the panels thereby preventing outward movement of the panel 210 relative to the panel 210". The filler can be either a continuous strip or short pieces located at intervals along the panels and is preferably of a resilient material which will not deteriorate quickly.
With proper proportioning the strip or filler will be a snug fit and tend to limit rattling noises and expansion creaking in the panels.
Further, if the strip is a close fit in channel 38a etc., then in the flush condition shown, the channel 38a" will be spread by the thickness of the tongue contained in the channel thereby making the front faces of adjacent panels coplanar.
Reference is finally made to Fig. 4 which illustrates an embodiment which would be preferable for use where only a lapped effect is desired. A first panel 310 is inter-engaged at a first marginal portion with a second panel 310' and at a second marginal portion with a third panel 310". The inter-engagement is similar to that used for the Fig. 3 embodiment but the panel 310 lacks structure necessary for inter-engagement in the flush condition. For ease of comparison parts correspond-ing generally with those described with reference to Fig. 3 will be given similar numerals but raised by one ~0~9~73 hundred. Such comparison will also show that this embodiment can be made for use in both lap and flush conditions by extending the flange.
- Although many variations can be made to the shape of the marginal portions described with reference to the previous embodiments, the principle explained with reference to these structures should be maintained for adequate results. It will also be appreciated that changes can be made to alter the appearance. For instance the main portion of the panel could be formed or textured to change the overall appearance of the siding and also with suitable modification a trim or ventilating strip could be inserted between adjacent panels. This is particularly evident in the Fig. 3 embodiment in which the spacer or filler 44 could have an extension projecting between adjacent panels if such a trim strip is desired.
