FIELD
The present disclosure relates, in general, to methods, systems, and apparatuses for implementing a tonneau cover.
BACKGROUND
Traditionally, truck cover systems are often used to protect cargo beds of pickup trucks. Cover systems often cover all or a portion of the cargo bed of the truck such that any items stored and/or hauled in the cargo bed are protected from outside elements and theft. Many conventional cover systems are releasably latched at the tailgate to a side rail of the truck to keep the cover closed. To facilitate access to the cargo bed, the latching structure of the cover system may be easily released. Conventional latching structures for these cover systems involve many inadequacies.
Hence, there is a need for more robust and scalable solutions for implementing methods, systems, and apparatus for implementing a tonneau cover, and more particularly, to methods, systems, and apparatus for implementing a latching system for a tonneau cover.

One general aspect of certain embodiments provides a truck cover system, which includes a side rail for mounting to a side wall of a truck bed, a first connection plate disengageably coupled to and extending from the side rail, a second connection plate disengageably coupled to the first bottom surface of the first connection plate, a cover removably accoupled to the second connection plate, a connector disengageably coupled the cover to the first connection plate and the second connection plate, a latching mechanism coupled to the cover and configured to releasably engage with a second bottom surface of the second connection plate. The side rail includes a first top surface, a side surface configured as an angled surface, and a first inner surface configured substantially in parallel with the side wall of the bed of the truck. The first connection plate includes a first recess on a first bottom surface of the first connection plate and a second recess on a second top surface of the first connection plate. The second connection plate includes a first protrusion on a third top surface of the second connection plate and a third recess on the third top surface of the second connection plate. The first protrusion is positioned within the first recess in an engaged position. The connector includes a first prong and a second prong.
According to another embodiment, the first recess of the first connection plate and the first protrusion of the second connection plate are T-shaped.
According to yet another embodiment, the first prong of the connector releasably engages with the second recess of the first connection plate, and the second prong of the connector releasably engages with the third recess of the second connection plate.
According to yet another embodiment, the connector further includes a gap located above the first connection plate and below the cover. The gap causes the second connection plate to bear the weight of the cover.
According to yet another embodiment, the second connection plate further includes a second inner surface configured in parallel with the side wall of the bed of the truck, and one or more first grooves located on the second inner surface of the second connection plate.
According to yet another embodiment, the truck cover system further includes a clamp configured to clamp a second inner surface of the second connection plate and the side wall of the bed of the truck together.
According to yet another embodiment, when the cover is closed, an upper surface of the connector releasably engages with and/or snaps into a bottom surface of the cover.
Another general aspect of certain embodiments includes a truck cover system, which includes a side rail configured to be coupled to a side wall of a bed of a truck, a cover removably attached to the side rail and configured to cover the bed of the truck, and a latching mechanism. The latching mechanism includes a latch housing attached to the cover and having a first open end and a second end, a latch extending through the first open end of the latch housing and configured to releasably engage with a bottom portion of the side rail, a cap having an opening and attached to the second end of the latch housing, a plunger attached to the latch and having a first plunger end partially extending through the opening of the cap, an anchor element attached to the first plunger end of the plunger and configured to stop the first plunger end from entering the latch housing, and a spring wrapped around the plunger. A first spring end of the spring is in contact with an interior surface of the cap. When the spring is compressed, the latch disengages with the bottom portion of the side rail.

The connector includes a first prong and a second prong.
According to another embodiment, the latching mechanism includes a latch housing attached to the cover and having a first open end and a second end, a latch extending through the first open end of the latch housing and configured to releasably engage with a bottom portion of the second connection plate, a cap having an opening and attached to the second end of the latch housing, a plunger attached to the latch and having a first plunger end partially extending through the opening of the cap, an anchor element attached to the first plunger end of the plunger and configured to stop the first plunger end from entering the latch housing, and a spring wrapped around the plunger. A first spring end of the spring is in contact with an interior surface of the cap. When the spring is compressed, the latch disengages with the bottom portion of the second connection plate. When the spring is uncompressed, the latch engages with the bottom portion of the second connection plate latching the cover in place.
According to yet another embodiment, the latching mechanism is configured to releasably engage with the bottom portion of the second connection plate. A second bottom surface of the latch is angled and the third top surface of the second connection plate is angled. Pulling on the cord causes the plunger to move toward the cap of the latch housing, causes the spring to compress, and causes the latch to disengage with the bottom portion of the second connection plate. Releasing the cord causes the plunger to move away from the cap of the latch housing, causes the spring to decompress, and causes the latch to engage with the bottom portion of the second connection plate.
According to yet another embodiment, the first prong of the connector releasably engages with the second recess of the first connection plate, and the second prong of the connector releasably engages with the third recess of the second connection plate. The connector further includes a gap located above the first connection plate and below the cover, and the gap causes the second connection plate to bear the weight of the cover.
It is to be appreciated that embodiments of the present disclosure provides many advantages over conventional techniques. Among other things, embodiments provide a truck cover system that can improve the releasable latching of the cover with the side rail. For some embodiments, the addition and operation of the plunger within the latch housing can ensure the latch properly aligns with the side rail to latch the cover in a closed position.

In other embodiments, when the cover 402 is closed, an upper surface of the connector 410 might releasably engage with and/or snap into a bottom surface of the cover 402. When the cover 402 is opened, the first prong 412 might snap out of the second recess 420 of the first connection plate 406 and the second prong 414 might snap out of the third recess 424 of the second connection plate 408. In other embodiments, when the cover 402 is opened, the first prong 412 might stay engaged with the recess 420 of the first connection plate 406, the second prong 414 might stay engaged with the third recess 424, and an upper surface of the connector 410 might disengage with a bottom surface of the cover 402. In some cases, the connector 410 might extend along the total length of the cover. The connector 410 might be formed from a flexible material that has the ability to bend with the cover 402. The first prong 412 and the second prong 414 may also be formed from a flexible material that has the ability to deform to releasably engage with and/or snap into the second recess 420 and the third recess 424. The flexible material of the connector 410, the first prong 412, and/or the second prong 414 might include fabric, plastic (e.g., vinyl), rubber, etc. The connector 410 might be configured to block precipitation and reduce the wear-and-tear of the truck cover 402.
In some embodiments, the gap 416 extending over first prong 412 and the first connection plate 408 causes the weight of the cover 402 to be held second connection plate 408. In other words, the force from the cover 408 pushes the second connection plate 408 downward. This causes the second connection plate 408 to distribute the force from the cover 402 to the first connection plate 406 via a pulling force instead of a pushing force. In other words, the second connection plate 408 pulls the first connection plate 408 and the side rail 404 downward. Advantageously, by distributing the force from the cover 402 in this manner, the side rail 404 is more securely held in place against the side wall of the truck bed, and, thus, the optional clamp 454 does not need to exert much force to couple the second connection plate 408 and the side rail 404 to the sidewall 464 of the truck bed 458. The optional clamp 454 merely serves as a backup to couple the side rail 404 to the sidewall 464 of the truck bed 458.
The cover system 400 might further include a latching mechanism 430. The latching mechanism 430 might be located on one side of the truck bed. The latching mechanism 430 might be coupled to the cover 402 and configured to releasably engage with the second connection plate 408. Additionally and/or alternatively, there may be two latching mechanisms 430 located on each side of the truck bed.
The latching mechanism 430 might include a latch housing 432 attached to the cover 402 via a latch attachment 434. The latch housing 432 might have a first open end 436 and a second end 438. The latching mechanism 430 might further include a latch 440 extending through the first open end 436 of the latch housing 432. The latch 440 might be configured to releasably engage with the second bottom surface 426 of the second connection plate 408. The latch 440 might have a sloped and/or angled surface and/or third bottom surface 442.
In some cases, the second end 438 of the latch housing 432 might have a smaller open end than the first open end 436 of the latch housing 432. The latching mechanism 430 might further comprise a cap (not shown) restricting the second end 438 of the latch housing 432. The cap may have an opening that is smaller than the first open end 436 of the latch housing 432.
The latching mechanism 430 might additionally include a plunger 444 attached to the latch 440. The plunger 444 might be attached to the latch 440 via a threaded connection (not shown). A first plunger end 446 might partially extend through an opening of the cap. The anchor element 448 might be attached to the first plunger end 446 of the plunger 444 and might be configured to stop the first plunger end 446 from entering the latch housing 432.
A cord 450 might loop and extend through a slot of the first plunger end 438 and/or anchor element 448. Two ends of the looped cord 450 might be attached together via one or more attachment mechanisms 452.
The latching mechanism 430 might also include a spring (not shown). The spring might be wrapped around the plunger 444. In some cases, a first end of the spring might be attached to the plunger 444. A second end of the spring may be in contact with an interior surface of the second end 438 of the housing 432 and/or an interior surface of the cap.
In operation, in order to open the cover 402, a user of the cover 402 may pull the cord 450 which pulls the plunger 444 further out of the second end 438 of the housing 432 and/or out of the opening of the cap, compresses the spring, and pulls the latch 440 into the open end 436 of the housing 432 causing the latch 440 to disengage with the second bottom surface 426 of the second connection plate 408. FIG. 4B shows the latch 440 in a locked position. In order to close the cover 402, the user of the cover 402 may push the cover 402 down causing the first prong 412 and the second prong 414 of the connector 410 to releasably engage with the second recess 420 of the first connection plate 406 and the third recess 424 of the second connection plate 408, respectively, causing the sloped surface 442 of the latch 440 to slide along the sloped surface 428 of the second connection plate 408, pushing the latch 440 toward the second end 438 of the housing 432, and compressing the spring. Once the sloped surface 442 of the latch 440 clears the sloped surface 428 of the second connection plate 408, the spring uncompresses pushing the latch 440 outward and away from the second end 438 of the housing 432 and enabling the latch 440 to releasably engage with the second bottom surface 426 of the second connection plate 408. FIG. 4A shows the latch 440 in an unlocked position.
The latching mechanism 430 will further be described below with respect to FIGS. 5, 6, and 7 below.
FIG. 5 is a partial front view of a cover system 500 with a latching mechanism 510 from FIGS. 4A, 4B, and 4C, in accordance with various embodiments.

The cap 608 might include an opening 610. The opening 610 may be a circular opening. The second end 606 of the housing 602 might have a smaller open end than the first open end 604 of the housing 602.
The latching mechanism 600 might further include a latch 612 extending through the first open end 604 of the latch housing 602. The latch 612 might be configured to releasably engage with a bottom portion of a side rail of a cover system. The latch 612 might fit snugly within the latch housing 602 and slidingly engage with latch housing 602.
In some instances, the latch 612 might comprise a square shaped portion 614, a sloped and/or angled surface 616, and a circular recess 618. The square shaped portion 614 of the latch 612 might be mostly or fully contained within the latch housing 602. The length of the square shaped portion 614 of the latch 612 may be less than the length of the housing 602. The sloped and/or angled surface 612 might extend from the latch housing 602 and slidingly engage with a sloped surface of a side rail of a cover. Additionally and/or alternatively, a bottom portion (not shown) of the latch 612 might releasably engage with a bottom surface of the side rail when the latch 612 is in a locked position. The circular recess 618 of the latch 612 might comprise one or more threads.
The latching mechanism 600 might additionally include a plunger 620 which may be attached to the latch 612. The plunger 620 might have a first end 622 comprising one or more threads. The first end 622 of the plunger 620 might be inserted into the circular recess 618 of the latch 612 and attached to the latch 612 via a threaded connection.
In some embodiments, the plunger 620 might further include a second plunger end 624. The second plunger end 624 might partially extend through the opening 610 of the cap 608 of the latch housing 602. An anchor element 626 might be attached to the second plunger end 624 of the plunger 620. In some cases, the anchor element 626 might be attached to the first plunger end 624 via a threaded connection. The anchor element 626 might have a circular shape which may be bigger than the circular opening 610 of the cap 608.

The latching mechanism 700 might include a latch housing 702. The latch housing 702 might have a first open end 704 and a second end 706. The first open end 704 may have a square shaped and/or rectangular shaped opening. The second end 706 might comprise a cap 708. The cap 708 might include an opening 710. The second end 706 of the housing 702 might have a smaller open end than the first open end 704 of the housing 702.
The latching mechanism 700 might further include a latch 712 partially extending through the first open end 704 of the latch housing 702. The latch 712 might be configured to releasably engage with a bottom portion of a side rail of a cover system. The latch 712 might fit snugly within the latch housing 702 and slidingly engage with latch housing 702. In other words, the latch 712 might be configured to slide in and out of the latch housing 702.
In some instances, the latch 712 might comprise a square shaped and/or rectangular shaped portion 714, a sloped and/or angled surface 716, and a circular recess 718. The square shaped portion 614 of the latch 712 might be mostly or fully contained within the latch housing 702. The length of the square shaped portion 714 of the latch 712 may be less than the length of the housing 702. The sloped and/or angled surface 712 might extend from the latch housing 702 and a bottom portion 720 of the latch 712 might releasably engage with a bottom surface of a side rail of a cover when the latch 712 is in a locked position. The circular recess 718 of the latch 712 might comprise one or more threads.
The latching mechanism 700 might additionally include a plunger 722 which may be attached to the latch 712. The plunger 722 might have a first end 724 comprising one or more threads. The first end 724 of the plunger 722 might be inserted into the circular recess 718 of the latch 712 and attached to the latch 712 via a threaded connection.
In some embodiments, the plunger 722 might further include a second plunger end 726. The second plunger end 726 might partially extend through the opening 710 of the cap 708 of the latch housing 702. An anchor element 728 might be attached to the second plunger end 726 of the plunger 722. The anchor element 728 might have a circular shape which may be bigger than the circular opening 710 of the cap 708. Thus, the anchor element 728 might be configured to stop the second plunger end 726 from entering the latch housing 702. The anchor element 728 might further comprise a slot 730.
A cord 732 might loop and extend through the slot 730 of the anchor element 728. Two ends of the looped cord 732 might be attached together via one or more attachment mechanisms 734.
The latching mechanism 700 might also include a spring 736. The spring 736 might be wrapped around the plunger 722. By wrapping the spring 736 around the plunger 722, the spring 736 is less likely to deform and can more easily maintain its shape. In some cases, a first end of the spring 736 might be attached to the first end 724 of the plunger 722. A second end of the spring 736 may be in contact with an interior surface of the second end 706 of the housing 702 and/or an interior surface of the cap 708. When the spring 736 is uncompressed, the force of the spring 736 might cause an interior surface of the anchor element 728 to be in contact with an exterior surface of the second end 706 of the housing 702 and/or an interior surface of the cap 708.
In operation, in order to open a cover, the anchor element 728 may be pulled via the chord 732 which pulls the plunger 722 further out of the second end 706 of the housing 702 through the opening 710 of the cap 708, compresses the spring 736, and pulls the latch 712 into the open end 704 of the housing 702. This causes the latch 712 to disengage with a bottom surface of a side rail of a cover system. In order to close a cover, the latch 712 may be pushed down, causing the sloped surface 716 of the latch 712 to slide along a sloped surface of a side rail, pushing the latch 712 toward the second end 706 of the housing 702, compressing the spring 703, and pushing the plunger 722 further out of the opening 710 of the cap 708. Once the sloped surface 716 of the latch 712 clears the sloped surface of a side rail, the spring 736 uncompresses pushing the latch 712 and plunger 722 outward and away from the second end 706 of the housing 702 and enabling the latch 712 to releasably engage with a bottom surface of the side rail.
