1. Field of the Invention
The invention relates generally to siding for a building and, more particularly, to a siding panel configured to resist wind loading.
2. Description of the Related Art
Numerous exterior treatment systems are known for use with buildings and the like. Among such exterior treatment systems are siding, such as vinyl and aluminum siding, as well as other known treatment systems.
Vinyl siding is particularly advantageous for a number of reasons. For instance, it is relatively inexpensive and is relatively simple to install. It has an extremely long service life, requires virtually no maintenance, and is available in numerous colors and textures, and it can be configured to have numerous different types of appearance.
Vinyl siding typically includes a plurality of siding panels that interlock with one another, and each such siding panel is mounted to a building with a number of fasteners such as nails, staples, and the like that are fasteningly received through a fastening hem on each siding panel. The fastening hem of a siding panel typically extends along one elongated side of the siding panel. The other side of the siding panel, i.e., the side opposite the fastening hem, typically is interlocked in some fashion with an adjacent siding panel. Accordingly, siding panels typically are installed with a relatively small quantity of fasteners. While vinyl siding has typically been effective for its intended purpose, vinyl siding has not, however, been without limitations.
Vinyl siding sometimes can be subjected to extreme wind loading, such as during inclement weather. Different regions of the country, typically have particular requirements that must be met by siding employed in that area, and a typical requirement is a wind loading rating. That is, siding must be able to withstand a certain wind load without becoming detached from the building. It thus would be desirable to provide an improved siding panel that has a relatively greater resistance to wind loading than other similar panels.
An improved siding panel has a fastening hem that includes an engagement member which is structured to extend outwardly from a building when the siding panel is mounted to the building. The engagement member is generally trapezoid-shaped in cross section and includes a first leg, a second leg, and an apex portion disposed therebetween, with spaced elongated openings being formed in the apex portion. The siding panel is cooperable with a fastener having an elongated shank and a head to mount the siding panel to a building. The siding panel is mounted to the building by receiving the shank through one of the openings. During certain wind loading, the apex portion is engageable with the head, which thereby deflects the first and second legs from a relaxed position to a deflected position where the edges of the opening can engage the shank of the fastener to provide a greater resistance to wind loading.
Accordingly, an aspect of the invention is to provide an improved siding panel that is configured to resist wind loading.
Another aspect of the invention is to provide an improved elongated siding panel structured to be mounted to a building with at least a first fastener, the fastener having a head and an elongated shank, the siding panel being structured to resist wind loading, wherein the general nature of the siding panel can be stated as including a body and an adjacent fastening hem. The fastening hem includes a base member and an engagement member, with the engagement member protruding outwardly from the base member and being structured to extend away from the building when the siding panel is mounted to the building. The engagement member includes a first leg, a second leg, and an apex portion extending between the first and second legs. The apex portion includes a number of relationally spaced elongated openings formed therein. The engagement member includes a number of pairs of elongated edges disposed adjacent the openings. The openings are structured to receive at least a portion of the shank therethrough when the panel is mounted to the building. The portions of the first and second legs adjacent the openings are movable between a relaxed position wherein the edges of a pair of edges are substantially disengaged from the shank and a deflected position wherein at least a portion of the edges of the pair of edges are engaged with the fastener. The engagement member is structured to be engageable with the head of the fastener during certain wind loading to move the first and second legs from the relaxed position toward the deflected position to resist the wind loading.
A further understanding of the invention can be gained from the following description of the Preferred Embodiment when read in conjunction with the accompanying drawings in which:
Similar numerals refer to similar parts throughout the Specification.
An improved siding panel 4 in accordance with the invention is indicated generally in
As can be best understood from
The body 16 includes a lock 28, a first course 32, a second course 36, and a tab 40. The lock 28 is disposed near the fastening hem 20 and is configured to be cooperable with an adjacent siding panel 4 (not expressly depicted herein) to connect together the two siding panels 4. The first course 32 and the second course 36 are, in the depicted exemplary embodiment, intended to each simulate a course of clapboard siding. The second course 36 terminates at the tab 40. The lock 28 includes a receptacle 44 formed therein, and the tab 40 of an adjacent siding panel 4 is receivable in the receptacle 44 in order to connect together the two adjacent siding panels 4.
The fastening hem 20 includes a base member 48 and an engagement member 52. The base member 48 includes a substantially planar first portion 56 and a substantially planar second portion 60. The first portion 56 is adjacent the body 16. The engagement member 52 extends between the first portion 56 and the second portion 60. The engagement member 52 protrudes outwardly from the base number 48 and, as can be understood from
As can further be understood from
As can be understood from
In the depicted exemplary embodiment, the pair of edges 80 and 84 of any given opening 76 are disposed within the radiused transition between the apex portion 72 and either of the first leg 64 and the second leg 68. It is understood that the openings 76 can be configured in different fashions to provide the edges 80 and 84 at different locations within the engagement member 52 than are expressly depicted herein without departing from the concept of the invention.
As can be understood from
When the siding panel 4 is initially mounted to the building 8, the shank 92 is received through one of the openings 76 and is received in a portion of the building 8. The head 88 typically is spaced slightly from the apex portion 72 to enable longitudinal growth and shrinkage as a result of thermal expansion and contraction of the siding panel 4. However, the head 88 need not be spaced from the apex portion 72 in order to provide the beneficial aspects of the invention.
In accordance with an aspect of the invention, the portions of the first leg 64 and the second leg 68 that are adjacent the shank 92 are elastically movable between a relaxed position i.e.,
When the first and second legs 64 and 68 are moved to the deflected position, however, as is depicted in
It can further be seen that the openings 76 are spaced away from the base member 48 and thus from the building 8, which facilitates an installer being able to clearly see the openings 76 during installation of the siding panel 4. The trapezoid-shaped configuration of the engagement member 52 results in a void region 96 that is disposed between the first and second portions 56 and 60. The engagement member 52 can be provided during formation of the siding panel 4 by providing additional tooling to form the engagement member 52 in the fastening hem. The depicted configuration of the engagement member 52 thus is relatively inexpensive to incorporate and does not meaningfully increase the size or weight of the siding panel 4, which is advantageous. The improved siding panel 4 with the improved fastening hem 20 having the engagement member 52 thus provides a greater degree of resistance to wind loading than similar siding panels.
