Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the support structure of the deck board disclosed in Patent Document 1 requires the first receiving surface and the second receiving surface of the luggage compartment in order to raise the first board part and the second board part, and it is necessary to provide means for raising in addition to the first board and the second board. Also, although a hinge is provided between the first board part and the second board part, it is merely a simple one that enables the folding of the first board part and the second board part, and there is a problem that the strength as a vehicle deck board is low. In order to maintain the strength of the vehicle deck board, it is necessary to provide a reinforcing member for the hinge.

[0005] The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle deck board that can stand up without relying on other members other than the vehicle deck board and can ensure sufficient strength.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention provides a vehicle deck board provided in a cargo compartment of a vehicle and having a first board portion and a second board portion, the vehicle deck board having a hinge mechanism that can connect and separate the first board portion and the second board portion. The hinge mechanism includes a first hinge shaft support portion that protrudes from an end surface of the first board portion toward the second board portion, a first hinge shaft portion having a semi-circular cross-section that extends along the end surface of the first board portion in a direction intersecting the protruding direction of the first hinge shaft support portion, a second rotating portion that protrudes from an end surface of the second board portion toward the first board portion and is rotatably fitted to the first hinge shaft portion, a second hinge shaft support portion that protrudes from the end surface of the second board portion toward the first board portion, a second hinge shaft portion having a semi-circular cross-section that extends along the end surface of the second board portion in a direction intersecting the protruding direction of the second hinge shaft support portion, and a first rotating portion that protrudes from the end surface of the first board portion toward the second board portion and is rotatably fitted to the second hinge shaft portion. The second hinge shaft support portion is provided between the first hinge shaft support portion and the first rotating portion, and the first hinge shaft support portion is provided between the second hinge shaft support portion and the second rotating portion.

[0007] In the present invention, the first board part and the second board part can be connected and separated by a hinge mechanism. A second rotating part protruding from the second board part is rotatably fitted to a first hinge shaft part having a semi-circular cross section extending along the end face of the first board part in a direction intersecting the protruding direction of the first hinge shaft support part in the hinge mechanism. A first rotating part protruding from the first board part is rotatably fitted to a second hinge shaft part having a semi-circular cross section extending along the end face of the second board part in a direction intersecting the protruding direction of the second hinge shaft support part in the hinge mechanism. A second hinge shaft support part is provided between the first hinge shaft support part and the first rotating part, and a first hinge shaft support part is provided between the second hinge shaft support part and the second rotating part. Therefore, when the second rotating part protruding from the second board part is rotated with respect to the first hinge shaft part and the first rotating part protruding from the first board part is rotated with respect to the second hinge shaft part, the second board part is rotated with respect to the first board part. The second board part can stand up by the upper surface of the second board part abutting against the end face of the first board part. Further, a second hinge shaft support part is provided between the first hinge shaft support part and the first rotating part, and a first hinge shaft support part is provided between the second hinge shaft support part and the second rotating part, and the respective parts constituting the hinge mechanism are provided alternately, so the hinge mechanism is robust and the strength of the vehicle deck board can be sufficiently ensured.

[0008] Further, in the above vehicle deck board, the first rotating part may be configured to be fitted with the second hinge shaft part and have an arc groove extending more than half a circle in the circumferential direction of the second hinge shaft part. In this case, since the first rotating part is fitted with the second hinge shaft part and has an arc groove extending more than half a circle in the circumferential direction of the second hinge shaft part, the first rotating part is less likely to come off from the second hinge shaft part. Therefore, there is no need to provide means for making it difficult for the first rotating part to come off from the second hinge shaft part.

[0009] Further, in the above vehicle deck board, it may have a skin material adhered to the surfaces of the first board part and the second board part, and the skin material may not be fixed to the hinge mechanism. In this case, since the skin material is not fixed to the hinge mechanism, the skin material does not prevent the second board part from standing up and falling down with respect to the first board part. As a result, the second board part can smoothly stand up and fall down with respect to the first board part.

[0010] In this case, in the above vehicle deck board, it may be configured that a plurality of the hinge mechanisms are provided. In this case, the strength of the first board part and the second board part can be further ensured.

Effect of the Invention

[0011] According to the present invention, it is possible to provide a vehicle deck board that can stand up without relying on other members other than the vehicle deck board and can ensure sufficient strength.

[0013] (First Embodiment) Hereinafter, the vehicle deck board according to the first embodiment will be described with reference to the drawings. In the present embodiment, a vehicle deck board provided in the luggage compartment of a wagon as a vehicle will be exemplified.

[0014] As shown in FIG. 1, in the luggage compartment 11 of the wagon 10, there are provided a vehicle deck board 20 forming a floor surface, a side deck board 13, and a side panel 14 forming a side wall of the luggage compartment 11. At the rear of the luggage compartment 11, there is provided a rear opening 15 that is opened and closed by a rear door (not shown). Rear side windows 16 are respectively provided at the upper parts of the side panels 14. In front of the luggage compartment 11, there is provided a rear seat 17.

[0015] The vehicle deck board 20 of the present embodiment has a first board part 21 and a second board part 22 provided in the luggage compartment 11. As shown in FIG. 2, the first board part 21 and the second board part 22 are rectangular plate members formed of resin. The first board part 21 is installed at the front in the luggage compartment 11. The second board part 22 is installed behind the first board part 21 in the luggage compartment 11 and on the side of the rear opening 15. Although not shown, a space for accommodating tools, a spare tire, etc. is formed below the vehicle deck board 20.

[0016] The first board part 21 has a front edge part 23 close to the rear seat 17, a rear edge part 24 facing the second board part 22, and a pair of left and right side edge parts 25 facing the pair of left and right side panels 14. The first board part 21 has a surface 26 on the luggage compartment 11 side and a back surface 27 on the body side. As shown in FIGS. 3 and 4, the rear edge part 24 has an end surface 28 substantially perpendicular to the surface 26. Near the side edge part 25 of the first board part 21, an overhanging part 29 that projects toward the second board part 22 more than the rear edge part 24 is formed.

[0017] The second board part 22 has a front edge part 33 facing the first board part 21, a rear edge part 34 close to the rear opening 15, and a pair of left and right side edge parts 35 facing the pair of left and right side panels 14. The second board part 22 has a surface 36 on the luggage compartment 11 side and a back surface 37 on the vehicle body side. As shown in FIGS. 3 and 4, the front edge part 33 has an end surface 38 substantially perpendicular to the surface 36. An overhanging part 39 that projects toward the first board part 21 more than the rear edge part 34 is formed on the second board part 22. A sheet-like skin material 30 is adhered to the surface 26 of the first seat part and the surface 36 of the second seat part. The skin material 30 is, for example, a punched carpet made of a resin non-woven fabric. In FIGS. 3, 5, and 6, for convenience of explanation, the illustration of the skin material 30 is omitted.

[0018] The vehicle deck board 20 has a hinge mechanism 40 that connects the first board part 21 and the second board part 22. As shown in FIG. 2, in this embodiment, a pair of left and right hinge mechanisms 40 are provided. As shown in FIG. 3, the hinge mechanism 40 includes a first hinge shaft support part 41, a first hinge shaft part 42, a first rotating part 43, a second hinge shaft support part 44, a second hinge shaft part 45, and a second rotating part 46.

[0019] The first hinge shaft support portion 41 protrudes from the end face 28 of the first board portion 21 toward the second board portion 22 and is integrally formed with the first board portion 21. As shown in FIGS. 4 and 5, the first hinge shaft support portion 41 is formed to have a thickness that is half of the thickness of the first board portion 21, and has a front surface 50, a back surface 51, a pair of side surfaces 52, and an arcuate surface 53 that extends from the front surface 50 to the back surface 51 near the tip. The front surface 50, the back surface 51, and the side surfaces 52 are flat surfaces.

[0020] The first hinge shaft portion 42 is a semi-cylindrical body with a semi-circular cross-section that extends along the end face 28 of the first board portion 21 in a direction intersecting the protruding direction of the first hinge shaft support portion 41, and has an arcuate front surface 54 and a flat back surface 55. The front surface 54 includes the same surface as the arcuate surface 53 of the first hinge shaft support portion 41. As shown in FIG. 3, both ends of the first hinge shaft portion 42 are supported near the tips of a pair of first hinge shaft support portions 41. The first hinge shaft portion 42 is integrally formed with the first hinge shaft support portion 41. The axial direction of the first hinge shaft portion 42 is the rotation center for the second board portion 22 to fall, and is a direction along the trailing edge portion 24 of the first board portion 21.

[0021] The first rotating portion 43 is installed at a distance from the first hinge shaft support portion 41. The first rotating portion 43 protrudes from the end face of the overhanging portion 29 of the first board portion 21 toward the second board portion 22. As shown in FIGS. 4 and 5, the first rotating portion 43 has a front surface 56, a back surface 57, a pair of side surfaces 58, an arcuate surface 59 that extends from the front surface 56 to the back surface 57, and an arcuate groove 60 formed along the trailing edge portion 24 on the back surface 57. The arcuate groove 60 is a groove that can be fitted with the second hinge shaft portion 45.

[0022] The second hinge shaft support portion 44 protrudes from the end face 38 of the second board portion 22 toward the first board portion 21 and is integrally formed with the first board portion 21. As shown in FIGS. 3 and 4, the second hinge shaft support portion 44 is formed to have a thickness that is half of the thickness of the second board portion 22, and has a front surface 70, a back surface 71, a pair of side surfaces 72, and an arcuate surface 73 that extends from the front surface 70 to the back surface 71 near the tip. The front surface 70, the back surface 71, and the side surfaces 72 are flat surfaces.

[0023] The second hinge shaft portion 45 is a semi-cylindrical body having a semi-circular cross-section that extends along the end face 38 of the second board portion 22 in a direction intersecting the protruding direction of the second hinge shaft support portion 44, and has an arcuate surface 74 on the front surface and a flat surface 75 on the back surface. The front surface 74 includes the same surface as the arcuate surface 73 of the second hinge shaft support portion 44. As shown in FIG. 3, both ends of the second hinge shaft portion 45 are supported near the tips of a pair of second hinge shaft support portions 44. The second hinge shaft portion 45 is integrally formed with the second hinge shaft support portion 44. The axial direction P of the second hinge shaft portion 45 is the rotation center for the second board portion 22 to fall down, and is a direction along the trailing edge portion 24 of the second board portion 22.

[0024] The second rotating portion 46 is installed at a distance from the second hinge shaft support portion 44. The second rotating portion 46 protrudes from the end face of the overhanging portion 39 of the second board portion 22 toward the first board portion 21. As shown in FIGS. 4 and 5, the second rotating portion 46 has a front surface 76, a back surface 77, a pair of side surfaces 78, an arcuate surface 79 that extends from the front surface 76 to the back surface 77, and an arcuate groove 80 formed along the leading edge portion 33 on the back surface 77. The arcuate groove 80 is a groove having an arcuate cross-section that can be fitted with the second hinge shaft portion 45.

[0025] In the hinge mechanism 40, the arcuate groove 80 of the second rotating portion 46 is fitted with the first hinge shaft portion 42. The first hinge shaft support portion 41 is located on both sides of the second rotating portion 46, and the arcuate surface 53 faces the end face of the overhanging portion 39. One of the first hinge shaft support portions 41 is located between the second rotating portion 46 and the other second hinge shaft support portion 44.

[0026] In the hinge mechanism 40, the arc groove 60 of the first rotating part 43 is fitted with the second hinge shaft part 45. The second hinge shaft support part 44 is located on both sides of the first rotating part 43, and the arc surface 73 faces the end surface of the protruding part 29. The other second hinge shaft support part 44 is located between the first rotating part 43 and one of the first hinge shaft support parts 41. Therefore, the element integrally formed with the first board part 21 in the hinge mechanism 40 and the element integrally formed with the second board part 22 in the hinge mechanism 40 are combined with each other in a different way.

[0027] A sheet-like skin material 30 is adhered to the surface 26 of the first sheet part and the surface 36 of the second sheet part, but the hinge mechanism 40 is not adhered to the skin material 30. The skin material 30 may be adhered to the first board part 21 and the second board part 22 so as not to prevent the second board part 22 from standing up and falling down. Specifically, it is not adhered to the surface of the protruding part 29 located on the second board part 22 side rather than the end surface 28 in the first board part 21. Also, it is not adhered to the surface of the protruding part 29 located on the second board part 22 side rather than the end surface 28 in the second board part 22. Further, the skin material 30 is not adhered to the surface 56 of the first rotating part 43 and the surface 76 of the second rotating part 46 either.

[0028] Next, the operation of the vehicle deck board 20 according to this embodiment will be described. When the vehicle deck board 20 is in a flat state, that is, the surface 26 of the first board part 21 and the surface 26 of the second board part 22 are substantially on the same plane and form the floor surface of the luggage compartment 11. The first board part 21 and the second board part 22 are supported by a body (not shown). At this time, the tip of the first hinge shaft support part 41 in the hinge mechanism 40 faces the end surface of the protruding part 39 of the second board part 22. Also, the tip of the first rotating part 43 in the hinge mechanism 40 faces the rear edge part 34 of the second board part 22. Further, the tip of the second hinge shaft support part 44 in the hinge mechanism 40 faces the end surface of the protruding part 29 of the first board part 21. Also, the tip of the second rotating part 46 in the hinge mechanism 40 faces the rear edge part 24 of the first board part 21 (see FIG. 3).

[0029] The pair of first hinge shaft support portions 41 are positioned so as to sandwich the side surface 78 of the second rotating portion 46, and the second rotating portion 46 and the second hinge shaft portion 45 are positioned so as to sandwich one of the first hinge shaft support portions 41. Further, the pair of second hinge shaft support portions 44 are positioned so as to sandwich the side surface 58 of the first rotating portion 43. Therefore, in the direction of the axis P, they are arranged in the order of the second hinge shaft support portion 44, the first rotating portion 43, the second hinge shaft support portion 44, the first hinge shaft support portion 41, the second rotating portion 46, and the first hinge shaft support portion 41. That is, the elements of the hinge mechanism 40 integrally formed with the first board portion 21 and the elements of the hinge mechanism 40 integrally formed with the second board portion 22 are combined with each other in a different way. As a result, in addition to the hinge mechanism 40, the strength of the first board portion 21 and the second board portion 22 is ensured.

[0030] Next, the case where the second board portion 22 stands up with respect to the first board portion 21 will be described. For example, when the driver stands up the second board portion 22, the driver opens the rear door (not shown) to open the rear opening 15. Next, the driver grasps the rear edge portion 34 of the second board portion 22 and rotates the second board portion 22 about the axis P to stand up. When the second board portion 22 is rotated so as to stand up, the arc surface 79 of the second rotating portion 46 in the second board portion 22 is rotated downward, and the surface 76 of the second rotating portion 46 approaches so as to face the end surface 28 of the rear edge portion 24 of the first board portion 21. As shown in FIG. 6, when the surface 36 of the second board portion 22 becomes substantially perpendicular to the surface 26 of the first board portion 21, as shown in FIG. 7(a), the surface 76 of the second rotating portion 46 abuts against the end surface 28 of the rear edge portion 24 of the first board portion 21. For this reason, the second board portion 22 does not fall down toward the first board portion 21.

[0031] Further, when the second board part 22 is rotated so as to stand up, the arc surface 73 of the second hinge shaft support part 44 is rotated downward, and the end surface 38 of the trailing edge part 34 of the second board part 22 approaches so as to face the surface 56 of the first rotating part 43. When the surface 36 of the second board part 22 becomes substantially perpendicular to the surface 56 of the first rotating part 43, as shown in FIG. 7(b), the end surface of the overhanging part 39 abuts against the surface 50 of the first hinge shaft support part 41. The end surface 38 of the second board part 22 abuts against the surface 56 of the first rotating part 43. Further, as shown in FIG. 7(c), the end surface 38 near the second hinge shaft support part 44 abuts against the upper surface of the overhanging part 29. Further, as shown in FIG. 7(d), the end surface 38 of the second board part 22 abuts against the surface 56 of the first rotating part 43. That is, the end surface 38 of the second board part 22 is supported by the surface 56 of the first rotating part 43. Therefore, the second board part 22 stands on its own, and even if the driver releases his hand from the second board part 22, the second board part 22 maintains the standing state.

[0032] Further, the sliding friction between the surface 54 of the first hinge shaft part 42 and the arc groove 80, and the sliding friction between the surface 74 of the second hinge shaft part 45 and the arc groove 60 of the first rotating part 43 are factors that prevent the second board part 22 from falling down. Further, when friction is generated by the contact between the side surface 78 and the side surface 52, the contact between the side surface 52 and the side surface 72, and the contact between the side surface 72 and the side surface 58, these are factors that prevent the second board part 22 from falling down. Therefore, in a state where the standing of the second board part 22 is maintained, the driver does not need to support the second board part 22 and can access the space below the luggage compartment 11.

[0033] Since the hinge mechanism 40 and the skin material 30 are not adhered, the skin material 30 does not prevent the second board part 22 from standing up in the process of making the second board part 22. When the standing second board part 22 is laid down, the driver may grasp the trailing edge part 34 of the second board part 22 and lay it down toward the rear opening 15. It is also possible to stand up the first board part 21 with respect to the second board part 22.

[0034] The vehicle deck board 20 according to the present embodiment has the following effects. (1) The first board part 21 and the second board part 22 can be connected and separated by a hinge mechanism 40. A second rotating part 46 protruding from the second board part 22 is rotatably fitted to a first hinge shaft part 42 having a semi-circular cross-section that extends along the end face 28 of the first board part 21 in a direction intersecting the protruding direction of the first hinge shaft support part 41 in the hinge mechanism 40. A first rotating part 43 protruding from the first board part 21 is rotatably fitted to a second hinge shaft part 45 having a semi-circular cross-section that extends along the end face 38 of the second board part 22 in a direction intersecting the protruding direction of the second hinge shaft support part 44 in the hinge mechanism 40. A second hinge shaft support part 44 is provided between the first hinge shaft support part 41 and the first rotating part 43, and a first hinge shaft support part 41 is provided between the second hinge shaft support part 44 and the second rotating part 46. Therefore, when the second rotating part 46 protruding from the second board part 22 is rotated with respect to the first hinge shaft part 42 and the first rotating part 43 protruding from the first board part 21 is rotated with respect to the second hinge shaft part 45, the second board part 22 is rotated with respect to the first board part 21. The second board part 22 can be erected by the surface 36 of the second board part 22 abutting against the end face 28 of the first board part 21. Also, a second hinge shaft support part 44 is provided between the first hinge shaft support part 41 and the first rotating part 43, and a first hinge shaft support part 41 is provided between the second hinge shaft support part 44 and the second rotating part 46, and the respective parts constituting the hinge mechanism 40 are provided alternately. For this reason, the hinge mechanism 40 is robust and can sufficiently ensure the strength of the vehicle deck board 20.

[0035] (2) It has a skin material 30 adhered to the surface 26 of the first board part 21 and the surface 36 of the second board part 22, and the skin material 30 is not fixed to the hinge mechanism 40. For this reason, the skin material 30 does not prevent the erection and collapse of the second board part 22 with respect to the first board part 21. As a result, smooth erection and collapse of the second board part 22 with respect to the first board part 21 are possible.

[0036] (3) Since a plurality of hinge mechanisms 40 are provided, the strength of the first board portion 21 and the second board portion 22 can be more ensured. Also, the standing state of the second board portion 22 is more easily maintained. Further, since the elements constituting the hinge mechanism 40 are integrated with the first board portion 21 or the second board portion 22, there is no separate part as the hinge mechanism 40, and a vehicle deck board 20 with the minimum number of parts can be realized.

[0037] (4) Since the hinge mechanism 40 is provided and the second board portion 22 can maintain the standing state, it is not necessary to provide a guide portion on the side panel 14 or a receiving groove for receiving the deck board on the body or the like that supports the vehicle deck board 20.

[0038] (5) The first hinge shaft portion 42 and the second hinge shaft portion 45 are semi-cylindrical bodies, and the arc groove 60 of the first rotating portion 43 and the arc groove 80 of the second rotating portion 46 are arc grooves corresponding to a half turn in the circumferential direction. When the skin material is not adhered, the connection and separation of the first board portion 21 and the second board portion 22 are easy.

[0039] (Second Embodiment) Next, the vehicle deck board according to the second embodiment will be described. In this embodiment, the configurations of the first rotating portion and the second rotating portion are different from those of the first embodiment. In this embodiment, for the same configurations as those in the first embodiment, the description in the first embodiment is incorporated and common reference numerals are used.

[0040] As shown in Fig. 8(a), in this embodiment, the arc groove 92 of the second rotating portion 91 in the vehicle deck board 90 is formed so as to fit with the first hinge shaft portion 42. The arc groove 92 is fitted with the first hinge shaft portion 42 and extends more than a half turn in the circumferential direction of the first hinge shaft portion 42. For this reason, the second rotating portion 91 is less likely to come off from the first hinge shaft portion 42. Therefore, it is not necessary to provide means for making it difficult for the second rotating portion 91 to come off from the first hinge shaft portion 42.

[0041] As shown in Fig. 8(b), the arc groove 94 of the first rotating part 93 in the vehicle deck board 90 is formed so as to fit with the second hinge shaft part 45. The arc groove 94 is fitted with the second hinge shaft part 45 and extends more than half a circle in the circumferential direction of the second hinge shaft part 45. For this reason, it becomes difficult for the first rotating part 93 to come off from the second hinge shaft part 45. Therefore, there is no need to provide a means for making it difficult for the first rotating part 93 to come off from the second hinge shaft part 45. Further, not only does it become difficult for the second rotating part 91 to come off from the first hinge shaft part 42, but also since it becomes difficult for the first rotating part 93 to come off from the second hinge shaft part 45, it becomes possible to realize a vehicle deck board that does not use the skin material 30.

[0042] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the invention. For example, the following modifications may be made.

[0043] ○ In the above-described embodiment, a pair of left and right hinge mechanisms are provided, but the present invention is not limited to this. Depending on the deck board, a single hinge mechanism may be used. Further, not limited to a pair of left and right, three or more hinge mechanisms may be provided. ○ In the above-described embodiment, the first (second) hinge shaft part is supported in a both-end supported manner by a pair of left and right first (second) hinge shaft parts, but the present invention is not limited to this. For example, a single first (second) hinge shaft part may be provided, and the first (second) hinge shaft part may be supported in a cantilevered manner by a single first (second) hinge shaft part. In this case, the space occupied by the hinge mechanism can be saved.
