Description

[Technical field]

[0001] The present invention relates to a tonneau cover device for covering a luggage compartment of a vehicle, and more particularly to a tonneau cover device which eliminates the need for a winding mechanism for the cover body to reduce weight, prevents the cover body from loosening during use, and maintains its aesthetic appearance. [Background technology]

[0002] A structure shown in Fig. 11 is known as a conventional tonneau cover device 100. Fig. 11 is a cross-sectional view illustrating the conventional tonneau cover device 100.

[0003] As shown in FIG. 11, the tonneau cover device 100 mainly comprises a first tonneau cover 101, a first winding device 102 that winds up the first tonneau cover 101, an end plate 103 that connects to the tip of the first tonneau cover 101, a second tonneau cover 104, and a second winding device 105 that winds up the second tonneau cover 104.

[0004] First winding device 102 has a winding mechanism (not shown) inside cylindrical case 102A, and this winding mechanism can wind up first tonneau cover 101 into the inside of case 102A and store it therein. Meanwhile, a user can pull out first tonneau cover 101 from case 102A by pulling end plate 103 located on the outside of case 102A.

[0005] The first winding device 102 can be detachably attached to the vehicle body by engaging engagement portions (not shown) at both ends of the case 102A with mounting portions (not shown) on the vehicle body side. As shown in the figure, the second winding device 105 is provided on the back side of the first winding device 102 and is handled integrally with the first winding device 102 (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2000-211433 A Summary of the Invention [Problem to be solved by the invention]

[0007] As described above, conventional tonneau cover device 100 has a structure in which case 102A of first winding device 102, which houses first tonneau cover 101, is attached to and detached from an attachment portion on the vehicle body. In addition, second winding device 105 is also integrally disposed with first winding device 102.

[0008] When the user is not using the tonneau cover device 100, such as when loading a large amount of luggage into the luggage compartment, the user can detach the first reeling device 102 from the vehicle body and remove the tonneau cover device 100 from the vehicle body. Then, when using the tonneau cover device 100, the user can attach the tonneau cover device 100 to the vehicle body by attaching the first reeling device 102 to the mounting portion of the vehicle body again.

[0009] However, the tonneau cover device 100 is composed of the first winding device 102 and the like, and is heavy, which poses the problem that the work of attaching and detaching the tonneau cover device 100 to and from the vehicle body is hard work. In addition, securing space to store the tonneau cover device 100 after it is removed from the vehicle body is also an issue.

[0010] Furthermore, if first tonneau cover 101 is left pulled out from case 102A, the weight of first tonneau cover 101 will act on it, making it impossible to support first tonneau cover 101 in an extended state, causing first tonneau cover 101 to sag.Furthermore, if first tonneau cover 101 overlaps the top surface of luggage or the like, the surface will become twisted, etc., which will impair the aesthetic appearance.

[0011] The present invention has been made in consideration of the above circumstances, and aims to provide a tonneau cover device that eliminates the winding mechanism for the cover body, thereby achieving weight reduction, while preventing the cover body from loosening during use and maintaining its aesthetic appearance. [Means for solving the problem]

[0021] First, a tonneau cover device 10 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the description of this embodiment, the same components will be designated by the same reference numerals as a rule, and repeated description will be omitted. In the following description, the up-down direction refers to the height direction of the vehicle 21, the left-right direction refers to the width direction of the vehicle 21, and the front-rear direction refers to the overall length direction of the vehicle 21.

[0022] FIG. 1 is a perspective view illustrating a tonneau cover device 10 of this embodiment. FIG. 2 is a cross-sectional view illustrating a second support portion 14 of the tonneau cover device 10 of this embodiment. FIG. 3 is a perspective view illustrating a luggage compartment 23 of a vehicle 21 in which the tonneau cover device 10 of this embodiment is disposed. FIG. 4 is a perspective view illustrating the state in which the tonneau cover device 10 of this embodiment is disposed in the vehicle 21. FIG. 5 is a top view illustrating the state in which the tonneau cover device 10 of this embodiment is disposed in the vehicle 21. FIG. 6 is a perspective view illustrating the wire winding mechanism 15 of the tonneau cover device 10 of this embodiment.

[0023] As shown in Figure 1, the tonneau cover device 10 mainly comprises a cover body 11 arranged above the luggage compartment 23 (see Figure 3), a board portion 12 that forms part of the cover body 11 and is arranged on the rear side of the cover body 11, a first support portion 13 that supports the front side of the cover body 11 in the vehicle width direction (left and right direction on the paper), a second support portion 14 that is arranged on the front end side of the board portion 12 and supports the cover body 11 and the board portion 12 in the vehicle width direction, and a wire winding mechanism 15 that is detachably connected to the vicinity of the rear end portion of the board portion 12.

[0024] The cover body 11 is, for example, a flexible member made by processing a cloth material or a synthetic resin material into a sheet shape, and has a size sufficient to cover almost the entire surface of the luggage compartment 23. The front end of the cover body 11 is fixed to the third support part 16, and the rear side of the cover body 11 is formed as a bag part 11A (see FIG. 2), and the core material 12A (see FIG. 2) of the board part 12 is stored inside the bag part 11A.

[0025] The third support portion 16 is, for example, a rod member made of aluminum material, and both ends of the third support portion 16 are detachably engaged with mounting portions 30 (see FIG. 3) provided on the trim 29 (see FIG. 3) of the luggage compartment 23. The third support portion 16 is disposed to bridge the trim 29 of the luggage compartment 23 in the vehicle width direction.

[0026] The board portion 12 has a core material 12A (see FIG. 2) made of a foamed resin material, cardboard material, or the like, and as described above, the core material 12A is stored in the bag portion 11A of the cover body 11, thereby forming a part of the cover body 11. The board portion 12 is repeatedly pulled toward the rear side of the vehicle 21 by the wire winding mechanism 15, but the presence of the core material 12A inside provides the desired durability.

[0027] The first support portion 13 has, for example, a pair of rod members 13A made of aluminum material and a resin receiving portion 13B that fixes both ends of the rod members 13A, and the rod members 13A are arranged stacked in the vehicle height direction (the vertical direction of the paper). The rod members 13A extend in the vehicle width direction of the vehicle 21, and the cover body 11 is inserted between the pair of rod members 13A to support the cover body 11 across the vehicle width direction. The receiving portion 13B of the first support portion 13 is detachably engaged with an attachment portion 31 provided on the trim 29 of the luggage compartment 23.

[0028] As shown in Fig. 2, the second support part 14 has a metal plate 14A attached to the front end of the core material 12A, and a resin piece part 14B that holds the metal plate 14A from the vehicle height direction. The metal plate 14A is a member that is approximately hexagonal in cross section and extends in the vehicle width direction, and is inserted and attached from the front end side of the core material 12A to increase the rigidity of the core material 12A and the second support part 14. The piece part 14B is formed by injection molding a thermoplastic resin such as polyethylene or polypropylene, and is made of a pair of upper and lower members that extend in the vehicle width direction. The metal plate 14A and the piece part 14B are arranged to bridge the trim 29 of the luggage compartment 23 in the vehicle width direction.

[0029] As described above, the bag portion 11A is formed on the rear side of the cover body 11, and the core material 12A and the sheet metal 14A are housed in the bag portion 11A. The piece portion 14B is fixed to the front and back sides of the bag portion 11A so as to overlap the sheet metal 14A. As shown in the figure, the front end of the piece portion 14B is open, and the cover body 11 and its sewn portion 11B are in a state of being freely movable relative to the piece portion 14B. The flat surfaces 14C of the piece portion 14B are fixed to the bag portion 11A so as to sandwich the bag portion 11A between the flat surfaces 14D of the sheet metal 14A. On the other hand, the rear end side of the piece portion 14B is fixed to the bag portion 11A so as to sandwich the core material 12A and the bag portion 11A.

[0030] Although details will be described later, the piece portion 14B on the back side (lower side in the vehicle height direction) of the board portion 12 has an abutment surface 14E formed on the rear side of the flat surface 14C. The flat surface 14C is a surface for the piece portion 14B to stand upright on the mounting portion 32 mainly when the board portion 12 is not pulled by the wire 15B, and the abutment surface 14E is a surface for the piece portion 14B to stand upright on the mounting portion 32 mainly when the board portion 12 is pulled diagonally downward rearward by the wire 15B. Therefore, the abutment surface 14E is a surface that is inclined diagonally upward toward the rear side in the overall length direction of the vehicle 21 (front-rear direction on the paper) with respect to the flat surface 14C.

[0031] The piece portion 14B is not necessarily limited to being composed of a pair of upper and lower members, but may also be a member having an abutment surface 14E arranged at least on the back side of the board portion 12 (the lower side in the vehicle height direction).

[0032] The wire winding mechanism 15 has a main body 15A that pays out or winds up the wire 15B by a known winding structure, one end of the wire 15B fixed to the main body 15A, and a hook portion 15C fixed to the other end of the wire 15B.

[0033] The main body 15A is disposed inside the back door 26 (see FIG. 3), and the wire 15B is led out to the luggage compartment 23 through an insertion hole (not shown) provided in the back door 26. A locking portion 42 (see FIG. 5) is provided at the rear end of the board portion 12, and the hook portion 15C is detachably locked to the locking portion 42. Note that the main body 15A is not limited to being disposed inside the back door 26, and the main body 15A may be disposed on the surface of a trim 26A (see FIG. 4) of the back door 26, for example.

[0034] 3, like a station wagon or the like, a vehicle 21 has a luggage compartment 23 behind a rear seat 22, and a back door 26 that can be opened and closed to cover an opening 25 of a rear bumper 24 of the vehicle 21 is disposed above the rear bumper 24. The back door 26 is connected to a vehicle body 27 at both edges of the upper end side of the opening 25 via a pair of stays 28, and the stays 28 automatically open and close the back door 26 via an electric opening / closing control device (not shown).

[0035] 3 shows a state in which the back door 26 is fully opened relative to the opening 25, and the luggage compartment 23 of the vehicle 21 is visible. A trim 29 is attached to both sides of the luggage compartment 23 in the vehicle width direction, and the trim 29 is formed with an attachment portion 30 that detachably engages with the third support portion 16, an attachment portion 31 that detachably engages with the first support portion 13, and a placement portion 32 on which the second support portion 14 is placed, from the front side. The attachment portions 30, 31 and the placement portion 32 are formed in pairs at approximately the same position on the trim 29, so that the first support portion 13, the second support portion 14, and the third support portion 16 are supported by the trim 29 so as to be approximately parallel to the floor mat 33.

[0036] Specifically, the mounting portion 30 has a recessed shape with an opening on the upper side and on the side facing the luggage compartment 23, is formed as a part of the trim 29, and houses the resin-made receiving portions 16A (see FIG. 4) at both ends of the third support portion 16. The bottom surface of the mounting portion 30 may have a known elastic engagement mechanism (not shown) that detachably engages with the receiving portions 16A. Similarly, the mounting portion 31 has a recessed shape with an opening on the upper side and on the side facing the luggage compartment 23, is formed as a part of the trim 29, and houses the receiving portions 13B (see FIG. 4) at both ends of the first support portion 13. The bottom surface of the mounting portion 31 may have a known elastic engagement mechanism (not shown) that detachably engages with the receiving portions 13B.

[0037] The placement portion 32 is a base on which the second support portion 14 is placed, and is, for example, a plate-shaped portion of the trim 29 protruding toward the luggage compartment 23. The upper surface of the placement portion 32 is approximately parallel to the floor mat 33. Although details will be described later, at least when the back door 26 is fully closed, the abutment surface 14E of the piece portion 14B abuts against the upper surface of the placement portion 32, and the piece portion 14B is placed on the placement portion 32 in a state in which it is inclined toward the rear side, so that the second support portion 14 bridges the trims 29 and supports the cover body 11 including the board portion 12.

[0038] Fig. 4 shows the tonneau cover device 10 disposed in the luggage compartment 23 of the vehicle 21 when the back door 26 is fully closed. The cover body 11 including the board portion 12 of the tonneau cover device 10 is disposed, for example, at approximately the same height as the upper end of the back seat of the rear seat 22. The tonneau cover device 10 does not have a roll-up storage case for the cover body 11, and the cover body 11 is always deployed above the luggage compartment 23. Note that Fig. 4 also shows the trim 26A of the back door 26.

[0039] As described above, the front end of the cover body 11 is supported across the vehicle width direction by the third support portion 16, the front side of the cover body 11 is supported across the vehicle width direction by the first support portion 13, and the rear side of the cover body 11 is supported across the vehicle width direction by the second support portion 14.

[0040] 5, two locking portions 42 are formed at the rear end of the board portion 12, and the locking portions 42 are disposed at positions approximately equidistant from the center in the vehicle width direction indicated by the dashed line 41. As shown in FIG. 6, the locking portions 42 have a frame portion 42A fixed to the core material 12A of the board portion 12, and a rod-shaped portion 42B bridging the frame portions 42A. The hook portion 15C of the wire winding mechanism 15 is hooked onto the rod-shaped portion 42B, so that the other end side of the wire 15B is detachably fixed to the board portion 12. The frame portion 42A of the locking portion 42 is fixed to the core material 12A, so that the locking portion 42 has a desired durability against repeated pulling by the wire winding mechanism 15.

[0041] Although details will be described later, when the back door 26 is in a fully closed state, the cover body 11 is pulled toward the rear side of the vehicle 21 by the wire winding mechanism 15, and the piece portion 14B is inclined, so that the cover body 11 in front of the piece portion 14B is tensioned. The wire winding mechanism 15 pulls the board portion 12 toward the rear evenly on the left and right in the vehicle width direction, thereby preventing the cover body 11 from shifting or twisting. The locking portion 42 may be located in a position that pulls the board portion 12 toward the rear side of the vehicle 21 approximately evenly, and may be disposed at one location in the center of the board portion 12 (at the location of the dashed line 41), or may be disposed at three or more locations evenly distributed at the rear end portion of the board portion 12.

[0042] With this structure, in tonneau cover device 10, substantially the entire surface of luggage compartment 23 is covered and concealed by cover body 11 including board portion 12, making it difficult to notice luggage and the like loaded in luggage compartment 23 from outside the vehicle. Furthermore, since tonneau cover device 10 has a structure that omits a winding device for winding up cover body 11 and a storage case, the mass of tonneau cover device 10 is lightened, and the burden of attaching and detaching the tonneau cover device to vehicle 21 is reduced.

[0043] Next, Figures 7 and 8 are cross-sectional views illustrating the usage state of the tonneau cover device 10 of this embodiment when the back door 26 is in a fully closed state. Figure 9 is a cross-sectional view illustrating the usage state of the tonneau cover device 10 of this embodiment when the back door 26 is in a fully open state. Figure 10 is a cross-sectional view illustrating the situation in which large luggage 54 is stored in the luggage compartment 23 when the back door 26 of the tonneau cover device 10 of this embodiment is in a fully closed state.

[0044] As shown in FIG. 7, the main body 15A of the wire winding mechanism 15 is disposed below the mounting portion 32 in the vehicle height direction and inside the trim 26A of the back door 26. The wire 15B is led out into the luggage compartment 23 through an insertion hole (not shown) provided in the trim 26A. In the tonneau cover device 10, the board portion 12 is pulled toward the rear side of the vehicle 21 by the wire 15B, so that the cover body 11 in front of the piece portion 14B can be tensioned. Therefore, in the wire winding mechanism 15, the lead-out amount L1 of the wire 15B from the trim 26A is set to be the minimum length when the back door 26 is in the fully closed state. The lead-out amount L1 of the wire 15B is set to have a length that does not cause the piece portion 14B to roll off the top surface of the mounting portion 32 when the board portion 12 is in the above-mentioned pulled state.

[0045] 8 shows an enlarged view of the area indicated by the circle 51 in FIG. 7. As described above with reference to FIG. 2, the contact surface 14E of the piece portion 14B is an inclined surface that is inclined obliquely upward from the flat surface 14C toward the rear end portion of the vehicle 21. When the back door 26 is in a fully closed state, the board portion 12 is pulled obliquely downward toward the rear side of the vehicle 21 by the wire 15B, so that the piece portion 14B rotates rearward on the upper surface of the mounting portion 32, and at least a part of the contact surface 14E of the piece portion 14B contacts the mounting portion 32, and the flat surface 14C moves away from the mounting portion 32.

[0046] As shown in the figure, the piece portion 14B hooks onto the end of the mounting portion 32 at the corner indicated by the circle 52 and stands upright on the abutment surface 14E, so that the second support portion 14 supports the cover body 11 across the vehicle width direction.

[0047] Specifically, the wire winding mechanism 15 changes the amount of wire 15B drawn out in conjunction with the opening and closing operation of the back door 26. When the back door 26 transitions from a fully open state to a fully closed state, the piece portion 14B first transitions from a state separated from the mounting portion 32 shown in Fig. 9 to a state in which the flat surface 14C stands on the upper surface of the mounting portion 32 shown in Fig. 2. Then, as the board portion 12 is pulled diagonally downward, the piece portion 14B rotates toward the rear side of the vehicle 21 and transitions to a state in which the piece portion 14B stands on the contact surface 14E as shown in Fig. 8.

[0048] When the piece portion 14B is erected on the contact surface 14E, the front side of the piece portion 14B moves upward from the placement portion 32, and the cover body 11 on the front side of the piece portion 14B is pulled and stretched toward the rear side of the vehicle 21 as shown by the arrow 53. As described above, the piece portion 14B is disposed across the vehicle width direction of the cover body 11, and is pulled approximately uniformly on the left and right sides by the wire 15B, thereby preventing the cover body 11 from loosening, twisting, or shifting. As a result, at least when the back door 26 is fully closed, the tonneau cover device 10 can maintain its beautiful appearance when in use. The board portion 12 of the cover body 11 has the core material 12A inside, which prevents the cover body 11 from loosening, twisting, or shifting.

[0049] 9, when the back door 26 is in a fully open state, the lead-out amount L2 of the wire 15B is at its maximum. That is, the wire 15B is sent out from a winding mechanism (not shown) of the main body 15A as the back door 26 moves from a fully closed state to a fully open state. Then, the cover body 11 including the board portion 12 is pulled by the wire 15B in conjunction with the opening operation of the back door 26 and moves to the upper side of the luggage compartment 23. The lead-out amount L2 of the wire 15B is set to have a length that does not cause the board portion 12 of the cover body 11 to hit the vehicle body 27 (see FIG. 3) of the opening portion 25 (see FIG. 3) in the fully open state.

[0050] As described above, unless the tonneau cover device 10 is removed from the luggage compartment 23, the cover body 11 is always deployed in the luggage compartment 23. When the back door 26 is fully opened in a state in which the cover body 11 is always deployed, the board portion 12 of the cover body 11 on the opening 25 side in particular moves upward in the luggage compartment 23 in conjunction with the movement of the back door 26. As a result, the cover body 11 including the board portion 12 is prevented from getting in the way when loading or unloading luggage into or from the luggage compartment 23.

[0051] As shown in Fig. 10, when the back door 26 is in a fully closed state and a large baggage 54 is loaded into the luggage compartment 23, the lead-out amount L3 of the wire 15B becomes longer than the lead-out amount L1 of the wire 15B shown in Fig. 7. As described above, the wire winding mechanism 15 is configured to pay out or wind up the wire 15B depending on whether the back door 26 is opened or closed. Conversely, the wire 15B can also be led out by being pulled by the board portion 12.

[0052] With this structure, when priority is given to the storability of luggage in the luggage compartment 23, luggage 54 that is taller than the seat back of the rear seat 22 can be loaded. In this case, a part of the cover body 11 moves upward in the luggage compartment 23 in accordance with the shape of the luggage 54, so that the wire 15B is pulled by the board portion 12 and is pulled out from the main body portion 15A.

[0053] At this time, the link portion 14B of the second support portion 14 separates from the upper surface of the loading portion 32, making it impossible to extend the cover body 11, and the cover body 11 becomes twisted or shifted according to the shape of the luggage 54, impairing the aesthetic appearance of the tonneau cover device 10 when in use. However, the desired luggage 54 can be loaded and transported in the luggage compartment 23 without being limited by the installation height of the cover body 11.

[0054] In this embodiment, the contact surface 14E of the piece portion 14B of the second support portion 14 is formed as a flat inclined surface, but the present invention is not limited to this. For example, the contact surface 14E of the piece portion 14B may be formed as a curved surface that is inclined obliquely upward toward the rear end portion of the vehicle 21 with respect to the flat surface 14C. Even in this case, when the back door 26 is in a fully closed state, the piece portion 14B rotates toward the rear side, and a part of the contact surface 14E contacts the upper surface of the mounting portion 32, so that the front side of the piece portion 14B is raised upward from the upper surface of the mounting portion 32, and the cover body 11 in front of the piece portion 14B is extended, and the beautiful appearance of the tonneau cover device 10 during use can be maintained.

[0055] Also, although the hook portion 15C of the wire winding mechanism 15 is hooked to the locking portion 42 at the rear end of the board portion 12, the present invention is not limited to this. For example, when the vehicle 21 is parked at a campsite and the back door 26 is fully open, the wire 15B may be led out and the hook portion 15C may be hooked to a pitched tent, and the wire 15B may be used as a hanger for towels or the like. In addition, various modifications are possible without departing from the scope of the present invention. [Explanation of symbols]
