Abstract
A method and apparatus for securing polymer plastic lumber. The apparatus includes a body having a first end, a second end, a first planar portion and a second planar portion.
The first planar portion and the second planar portion meet substantially at a right angle. Both the first planar portion and the second planar portion have at least one opening whereby fasteners are accommodated. A tab projects from the body. The tab is substantially co-planar with the first planar portion.
The tab has a slot that extends between the first end and the second end. Expansion and contraction of the polymer plastic board is accommodated by movement of the fastener along the slot.
The first planar portion and the second planar portion meet substantially at a right angle. Both the first planar portion and the second planar portion have at least one opening whereby fasteners are accommodated. A tab projects from the body. The tab is substantially co-planar with the first planar portion.
The tab has a slot that extends between the first end and the second end. Expansion and contraction of the polymer plastic board is accommodated by movement of the fastener along the slot.
Description
TITLE OF THE lNV~NllON:
method and apparatus for securing polymer plastic lumber NAME OF lNV~NlOR:
David L. Little FIELD OF THE lNV~NlION
The present invention relates to a method and apparatus for securing polymer plastic lumber.
BACKGROUND OF THE lNV~NLlON
Polymer plastic lumber differs from wood lumber. Unlike wood lumber, polymer plastic lumber experiences wide variations in length with variations in temperature. A 16 foot length of polymer plastic lumber may experience a variation in length of as much as 2 inches. During the coldest day of winter polymer plastic lumber will have a length of 15 feet 10 inches. During the warmest day of summer polymer plastic lumber will have a length of 16 feet. This thermal expansion and contraction has the effect of pulling out fasteners and buckling materials.
SUMMARY OF THE lNV~NLlON
What is required is a method and apparatus for securing polymer plastic lumber that will accommodate thermal expansion and contraction.
According to one aspect of the present invention there is provided an apparatus for securing polymer plastic lumber which includes a body having a first end, a second end, a first planar portion and a second planar portion. The first planar portion and the second planar portion meet substantially at a right angle. Both the first planar portion and the second planar portion have at least one opening whereby fasteners are accommodated. A tab projects from the body. The tab is substantially co-planar with the first planar portion. The tab has a slot that extends between the first end and the second end.
According to another aspect of the present invention there is provided a method for securing polymer plastic lumber. The first step involves providing a plurality of clips substantially as described above. The second step involves securing the clips to a support beam intended to support a polymer plastic lumber board. Fasteners are extended through the at least one opening in the first planar portion and the at least one opening in the second planar portion. The third step involves securing the polymer plastic lumber board to the support beam by extending a fastener through the slot in the tab and into the polymer plastic lumber board. Expansion and contraction of the polymer plastic board is accommodated by movement of the fastener along the slot.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, wherein:
FIGURE 1 is a perspective view of an apparatus for securing polymer plastic lumber in accordance with the teachings of the present invention.
FIGURE 2 is an end elevation view of the apparatus illustrated in FIGURE 1 in use securing polymer plastic lumber in accordance with the teachings of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an apparatus for securing polymer plastic lumber generally identified by reference numeral 10, will now be described with reference to FIGURES 1 and 2.
Referring to FIGURE 1, apparatus 10 includes a body 12 having a first end 14, a second end 16, a first planar portion 18 and a second planar portion 20. First planar portion 18 and second planar portion 20 meet substantially at a right angle 22. Both first planar portion 18 and second planar portion 20 have a plurality of openings 24, which are intended to accommodate fasteners as will hereinafter be further described.
A tab 26 projects from body 12. Tab 26 is substantially co-planar with first planar portion 18. Tab 26 has a slot 28 thatextends between first end 14 and second end 16 of body 12.
The use of apparatus 10 will now be described in relation to the preferred method and with reference to FIGURES 1 and 2.
The preferred method for securing polymer plastic lumber involves the following steps. Referring to FIGURE 1, the first step involves providing a plurality of clips substantially in the form of apparatus 10. Referring to FIGURE 1, the second step involves securing the clips 10 to a support beam 30.
Referring to FIGURE 2, clips 10 are secured to support beam 30 by extending fasteners 32 through openings 24 in first planar portion 18 and openings 24 in second planar portion 20.
Referring to FIGURE 2, the third step involves securing a polymer plastic lumber board 34 to support beam 30 by extending a fastener 32 through slot 28 in tab 26 and into polymer plastic lumber board 34. Fastener is not secured so tightly as to preclude movement. Expansion and contraction of polymer plastic board 34 is accommodated by movement of fastener 32 along slot 28. It will be appreciated that each polymer plastic lumber board 34 will require a number of clips 10 to secure it in position on support beam 30.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
