Retractable truck bed cover having slat array with flexible joiner members and shielded seams
View Patent ↗A retractable truck bed cover having an array of parallel aluminum slats joined together by connective hinges including leading and trailing edge configuration for improving the security of the cover by covering and concealing the seam between adjacent slats while improving the connective hinge's resistance to the effects of aging and/or exposure to temperature fluctuations. The truck bed cover connective hinge slat is designed to be in an array of discrete slats, which are joined to one another by means of joiner members secured at each end to slat end caps. The distal ends of the joiner members are attached to slat end caps at the distal ends of the slats, thereby preventing the joiner members from shrinking in relationship to the slats due to aging and/or exposure to temperature fluctuations.
1. A cover for a truck bed, the cover comprising:
a plurality of adjacent slats, each of the plurality of adjacent slats comprising:
a trailing edge;
a leading edge being on an opposite side of a width of the slat from the trailing edge;
an outer planar slat surface;
an inner planar slat surface;
a thickness between the outer planar surface of the slat and the inner planar surface of the slat;
a first step nib on the leading edge of the slat; and
a second step nib on the trailing edge of the slat, the second step nib configured to mate with the first step nib of an adjacent slat to form a closed joint limiting access from outside when the cover is in a closed extended position;
wherein the first step nib and the second step nip of each of the plurality of slats are located within the thickness of the slat.
2. The cover of claim 1 , further comprising at least one receptor channel extending downwardly from the thickness of each of the plurality of adjacent slats.
3. The cover of claim 2 , further comprising a connector section configured to be located within the at least one receptor channel of adjacent slats.
4. The cover of claim 3 , wherein the connector section is flexible.
5. The cover of claim 3 , wherein each of the plurality of adjacent slats comprise aluminum and the connector section comprises silicon.
6. The cover of claim 3 , wherein each of the plurality of adjacent slats comprise a protrusion extending downward from the thickness of the slat which is configured to mate with an upper surface of the connector section.
7. The cover of claim 1 , wherein the at least one receptor located on the leading edge of a slat is a mirror image of an at least one receptor located on the trailing edge of an adjacent slat.
8. The cover of claim 1 , wherein the first step nib and the second step nip are located fully within the thickness of the slat.
9. The cover of claim 1 , wherein the leading edge and the trailing edge of each of said plurality of adjacent slats are configured to form a half lap splice lap joint when the leading edge of a first slat member is connected with the trailing edge of a second slat member.
10. A system for covering a truck bed, the system comprising:
a pair of guide rails; and
a plurality of adjacent slats, each of the plurality of adjacent slats comprising:
a trailing edge;
a leading edge being on an opposite side of a width of the slat from the trailing edge;
an outer planar slat surface;
an inner planar slat surface;
a thickness between the outer planar surface of the slat and the inner planar surface of the slat;
a length extending between the plurality of guiderails;
a first step nib on the leading edge of the slat; and
a second step nib on the trailing edge of the slat, the second step nib configured to mate with the first step nib of an adjacent slat to form a joint;
wherein the plurality of adjacent slats are configured to slide within the pair of guide rails; and
wherein the first nib and the second nip of each of the plurality of slats are located between the outer planar slat surface and the inner planar slat surface of the slat and further comprising at least one receptor channel extending downwardly from the inner surface of each of the plurality of adjacent slats.
11. The system of claim 10 , wherein the first step nib and the second step nib overlap at the joint.
12. The cover of claim 10 , further comprising a connector section located within the at least one receptor channel of adjacent slats.
13. The cover of claim 12 , wherein the connector section is flexible.
14. The cover of claim 12 , wherein the plurality of slats comprise aluminum and the connector section comprises silicon.
15. The cover of claim 12 , wherein each of the plurality of adjacent slats comprising a protrusion extending into the thickness of the slat and configured to mate with an upper surface of the connector section.
16. The cover of claim 10 , wherein the at least one receptor located on the leading edge of a slat is a mirror image of at least one receptor located on the trailing edge of an adjacent slat.
17. The cover of claim 10 , wherein the first step nib and the second step nip are located fully within the thickness of the slat.
18. The cover of claim 10 , wherein the leading edge and the trailing edge of each of said plurality of adjacent slats are configured to form a half lap splice lap joint when the leading edge of a first slat member is connected with the trailing edge of a second slat member.
