Abstract
Description
- The present invention relates to a foldable tonneau cover and a waterproof seal thereof, and more particularly to a foldable tonneau cover for a pick-up truck having a waterproof flexible strip.
- A traditional pick-up truck has a cargo box used to carry various cargo. Generally, the cargo box is covered by a tonneau cover which is releasably clamped to and extended above the cargo box, so as to protect the carried cargo from adverse weather and improve the aesthetic appearance of the pick-up truck. Tonneau covers can be classified into hard-top type and soft-top type, wherein the hard-top type tonneau cover has a hard top made of rigid material, such as metal, fiberglass or the like, while the soft-top type tonneau cover has a soft top made of flexible material, such as canvas, vinyl plastic or a weather-resistant fabric. Moreover, the tonneau cover can be designed to provide a foldable function to help a user to conveniently extend or store the tonneau cover.
- Referring now to
FIGS. 1 , 2 and 3, schematic views of a traditional foldable tonneau cover system for a pick-up truck are illustrated, wherein atonneau cover system 10 is used to cover acargo box 21 of a pick-up truck 20, and thetonneau cover system 10 comprises a plurality offrame sections hinges 14, a plurality of clamps (not-shown) and at least onecover portion 15. The number of thecover portion 15 can be one or corresponding to that of the frame sections 11-13 (such as three). Thecover portion 15 is made of flexible or rigid material, and can be suitably fixed on the corresponding frame sections 11-13. Each of theframe sections 11 is constructed by a plurality of frame members. One of theframe sections adjacent frame section 12 through two or more of thehinges 14, so that all of the frame sections 11-13 can be adjusted to an extended position or a storage position. - When the
frame sections 11 are in the extended position as shown inFIG. 2 , the frame sections 11-13 are horizontally extended on twoside walls 22 and atailgate 23 of thecargo box 21, and fixed thereon by the clamps, so as to cover an inner space of thecargo box 21. When the frame sections 11-13 are in the storage position as shown inFIG. 3 , the frame sections 11-13 are folded and stacked on a front end of the twoside walls 22, so as to expose the inner space of thecargo box 21 for placing or taking cargo. - In the
tonneau cover system 10, each of thehinges 14 mainly comprises two hinge portions and a pivot axis, wherein each of the hinge portions is installed on frame members of one of the frame sections 11-13, while the pivot axis is pivotally connected between the two hinge portions. In order to prevent water leakage from the gap between any two adjacent frame sections 11-13, side surfaces of the frame members of the two adjacent frame sections 11-13 are provided with a pair of laterally-extending channels (unlabeled), wherein asealing strip 16 is disposed in each of the laterally-extending channels, respectively. Thus, when theframe sections 11 are in the extended position as shown inFIG. 2 , the twosealing strips 16 can be abutted against each other to provide a waterproof function for the frame sections 11-13. Furthermore, the external (or internal) side of each of thehinges 14 can be covered with another seal sheet (not-shown) to further enhance the waterproof function for the frame sections 11-13. - However, in a first case that a large-area elongated piece of the seal sheet is covered on the external side of the
hinge 14, when the two adjacent frame sections 11-12 are folded and stacked with each other, it is easy to irregularly twist the seal sheet between two outer surfaces of the two adjacent frame members, and thus the ideal folding angle (i.e. 180 degree) between the two adjacent frame sections 11-12 may not be carried out due to the jam of the seal sheet. On the other hand, in a second case that a small-area elongated piece of the seal sheet is covered on the internal side of thehinge 14, when the two adjacent frame sections 11-12 are horizontally extended, it is still easy to irregularly twist the seal sheet between two side surfaces of the two adjacent frame members, and thus the ideal extension angle (i.e. 0 degree) between the two adjacent frame sections 11-12 may not be carried out due to the jam of the seal sheet; and when the two adjacent frame sections 11-12 are folded and stacked with each other, it is easy to generate a pull force between two outer surfaces of the two adjacent frame members because the curve length of the seal sheet may be insufficient, and thus the ideal folding angle (i.e. 180 degree) between the two adjacent frame sections 11-12 may not be carried out due to the insufficient curve length of the seal sheet. - Moreover, the pivot axis of the
hinge 14 is installed at a fulcrum position between the two adjacent frame members, and thus occupies a certain space of the gap therebetween in the horizontally extended status. As a result, the pivot axis interfere with the installation and open/close operation of the seal sheet on the external or internal side of thehinge 14, so that it may increase the installation offset between thehinge 14, the seal sheet and the frame members. As a result, the installation yield may be affected, and the waterproof reliability thereof may be reduced. - As a result, it is necessary to provide a waterproof seal structure and a hinge structure for the foldable tonneau cover to solve the problems existing in the conventional technology, as described above.
- A primary object of the present invention is to provide a foldable tonneau cover for a pick-up truck and a waterproof flexible strip thereof, which is provided with a waterproof flexible strip continuously extended along the entire length of the two adjacent frame members without being interfered with by the hidden-type hinge substantially hidden within the frame members, so as to enhance the waterproof reliability thereof.

FIGS. 4 and 4A , the number of theframe sections foldable tonneau cover 30 is provided with afirst frame section 31 and asecond frame section 32, but not limited to include additional frame section or not. Thefirst frame section 31 has a plurality offirst frame members 311, tworigid cover plates 312 and afoam core 313. The number of thefirst frame members 311 can be four, and can be made of metal (such as aluminum, iron, stainless steel, copper or alloy thereof) or engineering plastic. Each set of thefirst frame members 311 can be used to construct a rectangular frame and define a rectangular space within the rectangular frame. Therigid cover plates 312 are made of rigid material, such as engineering plastic (such as polyamide 6 (PA6), polyamide 66 (PA66), polypropylene (PP), acrylonitrile-butadiene-styrene (ABS) copolymer, polycarbonate (PC) or polybutylene terephthalate (PBT), without limitation) or metal (such as aluminum, iron, stainless steel, copper or alloy thereof). Two of therigid cover plates 312 can be suitably covered and fixed on a top side and a bottom side of thefirst frame members 311, and the size of therigid cover plates 312 is slightly greater than that of the rectangular space defined by thefirst frame members 311. - Furthermore, referring to
