The siding unit of this invention comprises an outer panel and a backing board. The outer panel includes an upper marginal portion having a rearwardly extending downtumed hook part and a butt portion formed at the lower edge of the panel. The butt portion includes an upturned lip which interlocks with the outer panel of the siding unit in the lower adjacent course. The backing board has an upper edge which is of a reduced thickness to define a generally vertical lip. The backing board is positioned and secured against the building structure 'with the lower edge of the board resting upon the outer panel of the siding unit in the lower adjacent siding course. The outer panel of the siding unit is interlocked at its butt portion with the outer panel of the siding unit in the lower adjacent siding course and swung upwardly and rearwardly against the backing board with the hook part of the panel at its upper marginal portion being snapped over and interlocked with the lip at the upper edge of the backing board. In this manner, the outer panel is mounted to the building structure without the aid of staples, nails or the outer panel or the backing board of the siding unit in the next upper adjacent siding course. The siding units of this invention be be simply and rapidly applied to a building structure by one workman, even in inclement, windy weather.
Accordingly, it is an object of this invention to provide a siding unit for a building or like structure which can be applied by one workman in a simple and rapid manner.
It is another object of this invention to provide a siding unit for a building or like structure which is of economical construction and which can be applied in a simple and rapid manner on inclement and windy days as well as in pleasant weather.
It is a further object of this invention to provide a building siding unit comprising an outer panel and a backing board and in which only the backing board is fixedly'secured to the underlying building structure.
Still another object of this invention is to provide a method for attaching siding units to a building structure in which only the backing boards of the units are secured to the structure and the outer panels of the units are slidable relative to their respective backing boards and to each other.
Other objects of this invention will become apparent upon a reading of the inventions description.
BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of this invention has been chosen for purposes of illustration and description wherein:
FIG. 1 is a fragmentary perspective view of the siding units shown attached to a building structure.
FIG. 2 is a sectional view of the siding units taken along line 2-2 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment illustrated is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described in order to best explain the principles of the invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.
Each siding unit 5 includes an outer panel and a cooperating backing board 12. Outer panel 10 may be formed by extrusion or from sheet blanks which are shaped by a series of progressing bending or forming dies and may be of a plastic composition, such as polyvinylchloride, or metallic composition, such as aluminum. Backing board 12 is preferably formed of a rigid material such as insulative fiber board or a honeycombed light weight plastic.
Outer panel 10 includes an upper marginal portion 14, a face portion 16 depending from marginal portion 14, and a butt portion 18 extending from the lower edge 20 of face portion 16. Face portion 16 includes an integral retainer part 24 which extends along upper marginal portion 14. Retainer part 24 preferably comprises a downtumed forwardly projecting double-fold extension having an outer run 26 and a spaced inner run 28. A substantially horizontal flange extends rearwardly from the upper edge of outer run 26 and terminates in a downturned generally vertical lip 32. Inner run 28 of retainer part 24 in conjunction with face portion 16 defines an inverted channel 34. web 30 and lip 32 in conjunctionwith face portion 16 form a hook means. In other constructions of outer panel 11), retainer part 24 may be in the form of a clip such as that shown in FIG. 3 of U. S. Pat. No. 3,485,004.
Butt portion 18 of outer panel 10 includes a web which extends rearwardly from lower edge 20 of the face portion and which terminates in an upturned and preferably forwardly inclined lip 42. Lip 42 of the butt portion is adapted to be inserted upwardly into the retainer part channel 34 of an overlapped outer panel 10 of a siding unit in the adjacent lower siding course.
Backing board 12 has a front face 36, a rear face 38, an upper edge 43, and a lower preferably parallel edge 45. Rear face 38 of the backing board terminates spacedly from upper edge 43 to define a lip portion 44 at the upper edge of the backing. board. Lip portion 44 is separated from rear face 38 of the backing board by a shoulder 46.
To attach a siding unit of this invention to building structure 48, a backing board 12 is first positioned against structure 48 with its lower edge 45 resting upon web 30 at the upper marginal portion 14 of the outer panel 10 in the lower adjacent siding course. Nails 50, or similar securement means, are then driven through backing board 12 and into building structure 48 to anchor the backing board to the building structure. An outer panel 10 is then grasped by the workman with the butt portion 18 of the panel positioned below retainer part 24 and preferably against face portion 16 of the outer panel 10 of the siding unit in the lower adjacent course. The grasped panel is then slid upwardly causing lip 42 of its butt portion to be received within channel 34 of retainer part 24 of the outer panel 10 in the lower adjacent siding unit and slidably interlocked with the lower siding unit. With butt portion 18 of outer panel 10 so interlocked with the lower adjacent siding unit, the upper marginal portion 14 and face portion 16 of the outer panel is swung rearwardly against backing board 12 with lip 32 of the hook means at the upper marginal portion 14 of the panel being flexed upwardly and snapped downwardly over lip portion 44 of the backing board 12. With lip 32 of the outer panel located between lip portion 44 of the backing board and outer face 52 of building structure 48, the outer panel can be released as it will remain positioned against backing board 12. Another backing board 12 can now be grasped and positioned against building structure 48 with its lower edge 45 resting upon web 30 of the previously positioned outer panel 10. The sequence of securing the backing board to the building structure and attaching another panel to the board 12 is repeated as above described until siding of the building structure is completed.
The spacing between face portion 16 at retainer part 24 and lip 32 and the distance between web 30 and the upper edge of butt portion lip 42 of each panel 10 are so related in size to the thickness of lip portion 44 and the width respectively of backing board 12 that each panel 10 fits snugly in position upon its backing board when interlocked with an outer panel 10 in the lower adjacent course but not so tightly so as to prevent movement of the outer panel relative to its backing board and such interlocked outer panel during expansion and contraction of the panels due to atmospheric changes. Lip 32 of each panel 10 may be slightly outturned at its lower edge to facilitate its fit over lip portion 44 of its backing boardv To further facilitate attachment of the siding unit of this invention, each backing board may include a lip portion 44 at each of its upper edge 43 and lower edge 45 to enable the workmen attaching the siding to the building structure to reverse the backing board as the siding is being fitted for gables and similar areas where the siding unit must be shortened. The spacing between shoulder 46 and upper edge 43 of each backing board preferably exceeds the width of lip 32 of the outer panel as measured from the lips lower edge to panel web 30. Lip portion 44 of backing board 12 is spaced sufficiently from outer surface 52 of the building structure to permit lip 32 of the outer panel to be fitted over and behind the lip portion as shown in FIG. 2.
It can be seen from the above description that only the backing boards of the siding units of this invention are nailed to the building structure. This permits the outer panels of the siding units which are slidably interlocked together to expand or contract during use without buckling or distortion. Additionally, each of the outer panels of the siding units is positioned and held against the building structure by its backing board.
It is to be understood that the invention is not to be limited to the details herein given but may be modified within the scope of the appendedclaims.
