Abstract
Abstract A deck system including cooperating plastic planks, fastener covers and end caps. Each of the plastic planks has at least one channel in the upper surfaces which extends the length of the plank. Each channel includes at least one pair of opposed ledges. Each fastener cover is configured for insertion into one of the channels. The fastener cover is an elongate member having an upper face portion and a pair of legs downwardly depending from the upper face portion and extending substantially the entire length thereof. The fastener cover includes a pair of upper laterally projecting flanges and a pair of lower laterally projecting flanges. When a fastener cover is inserted into a channel, the pairs of upper and lower flanges receive the at least one pair of ledges with a gap sufficient to accommodate displacement of the fastener cover arising from ice expansion in the channel. Such a gap minimizes the likelihood of damage to the fastener cover and/or its expulsion from the channel as a consequence of ice expansion in the channel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
A deck system comprising: an elongate, substantially rigid plank having an upper face portion, a lower face portion and side walls connecting said upper and lower face portions; a pair of channels provided in said upper face portion and extending the length of said plank, said channels having opposed side walls joined by a base, said channel side walls being provided with at least one pair of opposed ledges; and at least one elongate fastener cover configured for insertion into at least one of said pair of channels, said fastener cover including a pair of laterally projecting upper flanges and a pair of laterally projecting lower flanges, whereby, when said at least one fastener cover is inserted into said pair of channels, said pairs of upper and lower flanges loosely receive said pair of ledges with a gap sufficient to accommodate displacement of said fastener cover arising from ice expansion in said channels.
Claim 2
Dependent Claim
153 words
A deck system comprising: an elongate, substantially rigid plank having an upper face portion, a lower face portion and side walls connecting said upper and lower face portions; a pair of channels provided in said upper face portion and extending the length of said plank, said channels having opposed side walls joined by a base, said channel side walls being provided with at least one pair of opposed ledges; and at least one elongate fastener cover configured for insertion into at least one of said pair of channels, said fastener cover including a pair of laterally projecting upper flanges and a pair of laterally projecting lower flanges, whereby, when said at least one fastener cover is inserted into said pair of channels, said pairs of upper and lower flanges loosely receive said pair of ledges with a gap sufficient to accommodate displacement of said fastener cover arising from ice expansion in said channels.
Claim 3
Dependent Claim
16 words
The deck system of claim 1 wherein said gap is at least about {fraction (1/16)} inch.
Claim 4
Dependent Claim
19 words
