Lid arrangement for a canister for a rollup truck bed cover

Abstract

A lid arrangement for a canister for a rollup truck bed cover comprises a lid and a canister. The canister has a main housing part and opposite housing end parts. The lid spans between said housing end parts across the main housing part, and the lid is pivotally connected to at least one of the housing end parts. The pivotal lid need not be taken fully off the canister when access is needed to the main housing part, e.g. to inspect the drain(s) or wipe up water inside the canister.

DETAILED DESCRIPTION OF THE INVENTION

(12) Below only the housing end part to be arranged in the right side of the truck bed, when seen in the forward driving direction, is described in detail. In should be emphasized that a similar the housing end part, but mirror-shaped, may be provided at the left side of the truck bed. The lid arrangement can also be used for canisters not having spiral guide track but instead rolls the truck bed cover onto a shaft or drum.

(13) FIG. 1 is a perspective view of a first embodiment of a lid 1. The lid 1 has a lid cover part 2 with a front lid edge 3, a rear lid edge 4 and opposite side edge 5,6. The front lid edge 3 has a front bending 7a, and the rear edge has a rear bending 7b, which bendings 7a,7b face away from the top side 8 of the lid 1.

(14) The bendings 7a,7b guide water away from the lid 1, and the front bending 7a also serves as a front pivot stop 9 when the lid is in open position, as will be described later in relation to FIGS. 2 and 3.

(15) A first pivot joint part 10 extends lengthwise the lid cover part 2 parallel to the front bending 7a. The first pivot joint part 10 consists of a first pivot member in form of a hook part 11 that is suspended to an underside 12 of the lid cover part 2 via a second pivot member 13. In an end view the first pivot member 11 and the second pivot member 13 has the outline of the mirror-shape of the number three.

(16) Between the front lid edge 3 and the rear lid edge 4 is disposed a first snap locking means 14 with a snapping hook 15 that catches below a second snap locking means 16 including a snapping web 17 on top of the housing end part 18, as seen in FIGS. 2-5. In FIGS. 2 and 3 the lid is open and in FIGS. 4 and 5 the lid is closed.

(17) The housing end part 18 defines a chamber 19 with a housing part end wall 20 provided with a spiral guide track 21 for controlling reception of the truck bed cover (not shown) during roll-up. The spiral guide track 21 is particularly preferred for hard truck bed covers assembled of rigid slats, e.g. the slat described in the applicant's Danish patent application no. PA 2019 70310 and the truck bed cover described in the applicant's international patent application no. PCT/DK2019/050125.

(18) Rolling-up is achieved by an electric motor (not shown) that has its shaft (not shown) rotateably journaled in a bearing bracket 22 at the housing part rear wall 23 of the housing end part 18. A drainage pipe 24 is provided towards the housing part front wall 25 to allow any water to exit the canister. The drainage pipe 24 may be connected to a drain system via a tube.

(19) The housing part upper wall 26 has the second snap locking means 16 protruding upright there from and front projections 27 facing towards the front wall of the truck bed (not shown) substantially perpendicular to a lengthwise extending axis of the lid 1.

(20) The front projections 27 carries the second pivot joint part 28 which points in the direction of the opposite housing end part 6, or said in another way: in parallel with the slats of the truck bed cover: aligned with the central axis of the spiral guide track and coaxial with the first pivot member 12 spaced from the housing part rear wall 23.

(21) The second pivot joint part 28 has a cup section 29 facing towards the hook part 11 to engage said hook part 11. The cup section 29 extends into the spring section 30 below the cup section 29 via a bead gap 31.

(22) A lengthwise extending bead 32 at the vicinity of the free end 33 of the hook part 11 sets in the bead gap 31 for applying tension to the spring section 30.

(23) The spring section 30 is composed of a first protruding retainer wall 34 and a parallel mirror-shaped second protruding retainer wall 35 spaced apart from the first protruding retainer wall 34. The retainer walls 34,35 have zig-zag shapes to resiliently absorb tension. The term “zig-zag” should not be construed as limiting the shape of the retainer walls 34,35 in that any shape or material that provides the resiliency of the retainer walls 34,35 can be used. The “zig-zag” shape can e.g. have pointed of curved apices.

(24) A housing part bottom wall 36 serves as a foot 37 that rests on the bottom of the truck bed or is chocked up on the truck bed bottom.

(25) The second pivot joint part 28 comprises the retainer member 38 composed of the spring section 30 and the cup section 29 and a holding-down member 39.

(26) The holding-down member 39 has a head part 40 and an upright stem 41, and the head part 40 fits pivotingly along the interior curvature of the hook part 11. A pivot space 42 for receiving the hook part 11 is delimited between the cup section 29 of the retainer member 38 and the holding-down member 39.

(27) In the closed position of the lid 1, as seen in e.g. FIGS. 4 and 5, the rear lid edge 4 does not extend the whole distance to the housing part rear wall 23 to cover the whole width of the canister 44. A space 46 is left for entry of the truck bed cover. The front slat (not shown) or front profile (not shown) of the array of assembled slats (not shown) of the truck bed cover (not shown) enters the most exterior winding of the spiral track guide 21 below the rear lid edge 4 to cover the canister opening 43 of the canister 44 so that the rear bending 7b is just above the truck bed cover.

(28) FIGS. 6-8 show the canister 44 with the lid arrangement of the present invention with the lid 1 in closed and open positions.

(29) FIG. 6 shows that the canister 44 is composed of the main housing part 45, assembled to right housing end part 18a and opposite left housing end part 18b. The lid 1 is closed in FIG. 6. The housing end parts 18a,18b can be assembled to the main housing part 45 by any appropriate means, including connecting means on any of said parts 45,18a,18b, and fasteners (not shown) be used to secure such connecting means to each other to obtain the canister receptacle for the roll-up truck bed cover (not shown).

(30) As seen best in FIGS. 7 and 8 the main housing part 45 has first connecting means 47 in form of first securing webs 48 that protruded axially beyond side edges 5,6 of the lid 1 to secure the respective housing end parts 18a,18b. First fastening holes 49 are provided in the first securing webs 48 to fasten the opposite housing end parts 18a,18b to any of the housing part rear wall 23, the housing part front wall 25, and housing part bottom wall 36, optionally to appropriate second connecting means on said walls 23,25,36.

(31) The lid 1 is pivotably mounted along the housing part front wall 25 between the closed position seen in FIG. 7 and the open position seen in FIG. 8. As seen best in the view of FIG. 8 the first pivot joint part 1, the bendings 7a,7b and the first snap locking means 14 extends the full length of the present embodiment of a lid 1, but these means can in the alternative just be provided at the side edges 5,6, of the lid 1.

(32) FIGS. 9 and 10 show an alternative lid arrangement that substantially corresponds to the lid arrangement shown and described in relation to FIGS. 1-8. For like parts same reference numerals are used. The lid arrangement shown in FIGS. 9 and 10 differs from the lid arrangement shown in FIGS. 1-6 mainly in the implementation of a second embodiment of a lid 1′. The only difference between the first embodiment of a lid 1 and the second embodiment of a lid 1′ is that second embodiment of the lid 1′ is wider than the lid 1, so that the rear lid edge 4 extends closer to the housing part rear wall 23, whereby the space 46 left for entry of the truck bed cover is smaller than for the lid arrangement implementing the first embodiment of a lid 1. This smaller space contributes in reducing entry of water when the lid 1′ is closed. Preferably the additional width corresponds to a width of a rigid slat of the roll-up truck bed cover.

(33) The lid arrangement that implements a second embodiment of a lid 1′ is seen on a second embodiment of a canister 44″ having a reinforcing rib 50 on the housing part rear wall 23. Similar reinforcing ribs may be provided on any canister wall or on the lid 1′ to provide further structural integrity to the lid 1′ and the canister 44′, respectively, when said lid 1′ and said canister 44′ is subjected to the forces from the roll-up truck bed cover when said cover is rolled in an out of the canister 44′.
