Abstract
Abstract A foldable cover assembly is particularly adapted for pick-up trucks and has a plurality of slat members with a longitudinal slot extending along each end. Each slot communicates with a more extensive cavity. A plurality of hinge members connect the slat members together. The hinge members are flexible and resilient, having a center portion and relatively thin flange portions extending longitudinally along each end of the center portion. The hinge members have enlarged, elongated portions extending along outer ends of the flange portions. The flange portions and protrusions are shaped so the flange portions extend through the slots of the slat members, while the protrusions are retained in the cavities of the slat members. A pair of guide members are positioned in parallel, spaced-apart relationship. The guide members have inner portions for slidably receiving sides of the slat members and the hinge members thereon. A plurality of retainers slidably connect alternating hinge members to the guide members. Preferably a pair of flap members are hingedly connected to each guide member for covering sides of the slat members and the hinge members when the cover assembly is unfolded.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
243 words
A foldable cover assembly comprising: a frame including a pair of parallel guide channel members; a foldable cover on the guide channel members including interconnected, alternating rigid slat members and flexible hinge members , the slat members each having a longitudinal slot extending along each end thereof, each said slot communicating with a more extensive interior cavity, the hinge members each being flexible and resilient and having a centre portion, a relatively thin flange portion extending longitudinally along each end of the centre portion, and an enlarged, elongated portion extending along an outer end of each said flange portion, the flange portions and enlarged portions being shaped so the flange portions can extend through the slots of the slat members while the enlarged portions are retained in the cavities of the slat members; connecting means for connecting every second hinge member to each said guide channel member in a manner to permit sliding along the guide channel members and to prevent lifting of said every second hinge member away from the guide channel members so the slat members and the hinge members are flat against the guide channel members and the cover extends along the lengths of the guide channel members when the cover is unfolded, and the slat members are stacked adjacent each other in a vertical position near one end of the guide channel members and the hinge members form curved loops interconnecting adjacent slat members when the cover is folded.
Claim 2
Dependent Claim
243 words

Claim 3
Dependent Claim
37 words
A foldable cover assembly as claimed in claim 1, wherein the slat members have flat top and bottom surfaces and end portions on each side of said slots at right angles to the top and bottom surfaces.
Claim 4
Dependent Claim
38 words
A foldable cover assembly as claimed in claim 2, wherein the slat members are hollow with interior ribs extending perpendicular to the top and bottom surfaces, each said cavity extending from one said rib to the end portions.
Claim 5
Dependent Claim
56 words
A foldable cover assembly as claimed in claim 1, wherein each hinge member is unitary and flat when undeformed, the centre portion having a flat top and a flat bottom, the flange portions being parallel to the top and the bottom, the enlarged portions being flat and perpendicular to the centre portion and the flange portions.
Claim 6
Dependent Claim
33 words
A foldable cover assembly as claimed in claim 4, wherein each said hinge member has sealing means on the enlarged portions for sealing the hinge members within the cavities of the slat members.
Claim 7
Dependent Claim
53 words
A cover assembly as claimed in claim 1, further including flap members connected to the guide channel members by hinges and each having a top positioned to overly sides of the cover when unfolded, the hinges being positioned to permit the flap members to swing away from the cover to permit folding thereof.
Claim 8
Dependent Claim
30 words
A foldable cover assembly as claimed in claim 6, wherein each of the flap members has a flat top which covers said sides of the slat members and hinge members.
Claim 9
Dependent Claim
64 words
A foldable cover assembly as claimed in claim 6, wherein the guide channel members each comprises an elongated member having a longitudinal channel along an inner portion thereof, the channel having a top for slidably receiving the slat members and the hinge members and a relatively narrow central slot extending along the top and communicating with a more extensive interior cavity of the channel.
Claim 10
Dependent Claim
74 words
A foldable cover assembly as claimed in claim 8, wherein the connecting means each comprises a pair of retaining members extending from each said every second hinge member, each said retaining member having a first portion near said every second hinge member shaped to project slideably through the slot in one of the channels and an enlarged second portion shaped to move slideably in the interior cavity of the channel and be retained therein.
Claim 11
Dependent Claim
44 words
A foldable cover assembly as claimed in claim 8, wherein each said guide channel member has an outer portion with a partially cylindrical recess, each of the flap members having a generally cylindrical end shaped to fit in the recess to form said hinges.
Claim 12
Dependent Claim
