[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-341431 Summary of the Invention [Problem to be solved by the invention]

[0004] There has been a demand for a versatile vehicle deck device that can be adapted to a variety of vehicle models with different widths and recess depths. [Means for solving the problem]

[0005] A vehicle deck device for solving the above problems includes a deck board that opens or closes a recess provided in a floor of a luggage compartment of the vehicle, and a support frame that supports the deck board, the support frame having a front frame extending in the left-right direction of the vehicle, and a rear frame that extends in the left-right direction behind the front frame in the front-to-rear direction of the vehicle, the deck board opening or closing the recess by sliding in the front-to-rear direction relative to the support frame or rotating around the front frame as an axis, the front frame having a cylindrical front inner member extending along the left-to-right direction, and a pair of front outer members that overlap both ends of the front inner member in the left-to-right direction and are slidable in the left-to-right direction relative to the front inner member, the front frame having a cylindrical rear inner member extending along the left-to-right direction, the support frame has a pair of front support parts extending from the front inner member in a direction perpendicular to the left-right direction, a cylindrical lower member protruding from the rear frame upward in the up-down direction of the vehicle, and a pair of rear support parts having an upper member on which the deck board is placed, the upper member overlapping the lower member and being slidable in the up-down direction relative to the lower member, the deck board having a pair of rail holes through which the pair of front support parts are inserted, both end parts of the front inner member are slidable in a circumferential direction relative to the pair of front outer members, and the deck board is slidable in the fore-and-aft direction relative to the pair of front support parts.

[0006] According to the above configuration, the deck board can open or close the recess by sliding in the front-to-rear direction relative to the pair of front support parts. Furthermore, both ends of the front inner member can slide in the circumferential direction relative to the pair of front outer members. Therefore, the deck board can open or close the recess by rotating, together with the pair of front support parts and the front inner member, about the axis of the pair of front outer members.

[0007] The left-right length of the front frame can be adjusted by sliding the pair of front outer members of the front frame left-right relative to the front inner member. Similarly, the left-right length of the rear frame can be adjusted by sliding the pair of rear outer members of the rear frame left-right relative to the rear inner member. Therefore, the vehicle deck device can be adapted to a variety of vehicle models with different vehicle widths. Furthermore, the up-down length of the rear support part can be adjusted by sliding the upper member of the rear support part up-down relative to the lower member. Therefore, the vehicle deck device can be adapted to a variety of vehicle models with different recess depths. Therefore, a vehicle deck device with excellent versatility can be provided.

[0008] The vehicle deck device includes a stopper device that can fix the position of the deck board in the fore-and-aft direction relative to the support frame, the stopper device having a gas spring with a locking function and a lever for operating a locking function of the gas spring with a locking function, the gas spring with a locking function being attached to the front inner member and having a cylinder tube that extends in a direction perpendicular to the left-right direction and a piston rod that extends from the cylinder tube, the lever being connected to a tip end of the piston rod and attached to the deck board, when the lever is operated the locking function is released, thereby making it possible to adjust the amount of protrusion of the piston rod from the cylinder tube, and when the lever is not operated the locking function is activated, thereby fixing the amount of protrusion of the piston rod from the cylinder tube.

[0009] According to the above configuration, the operator of the vehicle deck device can slide the deck board in the fore-and-aft direction relative to the support frame by operating the lever, and can fix the position of the deck board in the fore-and-aft direction relative to the support frame at a desired position by releasing the lever.

[0010] In the vehicle deck device, the upper member may have a rotation shaft extending in the left-right direction, and a roller that rotates integrally with the rotation shaft and on which the deck board is placed.

[0011] According to the above configuration, the rollers rotate as the deck board slides in the front-to-rear direction, allowing the deck board to slide smoothly. The vehicle deck device may further include an auxiliary mechanism that is provided on the front frame and assists in the pivoting operation of the deck board, the auxiliary mechanism having a torsion spring and a fixed member that is arranged within the front inner member, a first arm of the torsion spring being attached to the front outer member and a second arm positioned opposite the first arm being attached to the fixed member, the fixed member being unable to rotate circumferentially relative to the front inner member and being movable in the left-right direction relative to the front inner member, and the torsion spring biasing the front inner member so that the pivoting direction of the front inner member relative to the pair of front outer members is a direction in which the deck board rises.

[0012] According to the above configuration, the fixed member cannot rotate circumferentially relative to the front inner member. Therefore, the biasing force of the torsion spring is transmitted to the front inner member via the fixed member. The biasing force of the torsion spring can assist the rotational movement of the front inner member when the deck board is raised. Furthermore, since the deck board is maintained in a raised state after being raised, the recess can be maintained in an open state.

[0013] The fixing member is also movable left and right relative to the front inner member, so that when the pair of front outer members slide left and right relative to the front inner member, the assisting mechanism can also move left and right within the front inner member.

[0014] In the vehicle deck device, the rear support portion may include a spacer that is interposed between the rear frame and the upper member in the vertical direction and supports the upper member.

[0015] According to the above configuration, the deck board can be stably supported by the pair of rear support portions. [Effects of the Invention]

[0018] An embodiment of a vehicle deck device will be described below with reference to Figures 1 to 7. In the following description, the terms "front," "rear," "left," "right," "up," and "down" refer to the state in which the driver of the vehicle is facing forward (forward). The left-right direction coincides with the vehicle width direction.

[0019] As shown in FIG. 1, a luggage compartment 101 is provided in the rear of the vehicle 100. The vehicle 100 has a recess 103 recessed from a floor 102 of the luggage compartment 101. The recess 103 is used as a storage space for storing, for example, a spare tire. A pair of protrusions 104 protrude from a bottom surface 103a of the recess 103. The pair of protrusions 104 are arranged side by side with a gap in between in the left-right direction X. The vehicle 100 has a pair of overhanging portions 105 that overhang inward in the left-right direction X in the luggage compartment 101. Each of the overhanging portions 105 is provided with a hook mounting portion 106.

[0020] <Configuration of vehicle deck device> As shown in FIG. 2, the vehicle deck device 10 is provided in a luggage compartment 101. The vehicle deck device 10 includes a deck board 11 and a support frame 12. The deck board 11 opens or closes a recess 103. Note that FIG. 2 illustrates the vehicle deck device 10 when the recess 103 is closed. The support frame 12 supports the deck board 11.

[0021] As shown in Fig. 3, the support frame 12 has a front frame 13, a rear frame 14, a pair of front support portions 15, and a pair of rear support portions 16. The front frame 13 and the rear frame 14 each extend in the left-right direction X. The rear frame 14 is located rearward of the front frame 13 in the front-to-rear direction Y. The pair of front support portions 15 and the pair of rear support portions 16 support the deck board 11. The pair of rear support portions 16 are located rearward of the pair of front support portions 15 in the front-to-rear direction Y.

[0022] The front frame 13 has a front inner member 31 and a pair of front outer members 32. The front inner member 31 extends along the left-right direction X. The front inner member 31 of this embodiment is cylindrical. The pair of front outer members 32 are located at both ends of the front inner member 31 in the left-right direction X. The front outer member 32 of this embodiment is cylindrical with a bottom. The front outer member 32 has a disk-shaped bottom 32a and a cylindrical tube portion 32b standing upright from the peripheral edge of the bottom 32a.

[0023] As shown in FIG. 4 , the pair of front outer members 32 overlap both end portions of the front inner member 31. In this embodiment, the inner diameter of the tubular portion 32b of the front outer member 32 is larger than the outer diameter of the front inner member 31. The left end portion of the front inner member 31 is inserted into the front outer member 32 located on the left side. The right end portion of the front inner member 31 is inserted into the front outer member 32 located on the right side. The pair of front outer members 32 are slidable in the left-right direction X relative to the front inner member 31. In addition, both end portions of the front inner member 31 are slidable in the circumferential direction relative to the pair of front outer members 32. The front inner member 31 is rotatable about the pair of front outer members 32.

[0024] The front frame 13 is disposed outside the recess 103. The front frame 13 is located forward of the recess 103. A front bracket 17 is attached to the tubular portion 32b of each front outer member 32. The front bracket 17 is attached to the vehicle 100 via a hook H attached to the hook attachment portion 106. Therefore, the pair of front outer members 32 are attached to the vehicle 100.

[0025] As shown in FIG. 3 , the rear frame 14 has a rear inner member 41 and a pair of rear outer members 42. The rear inner member 41 extends along the left-right direction X. In this embodiment, the rear inner member 41 has a rectangular cylindrical shape. The pair of rear outer members 42 are located at both ends of the rear inner member 41 in the left-right direction X. In this embodiment, the rear outer member 42 has a bottomed rectangular cylindrical shape. The rear outer member 42 has a rectangular plate-shaped bottom portion 42a and a rectangular cylindrical tubular portion 42b erected from the peripheral edge of the bottom portion 42a.

[0026] As shown in Fig. 5, the pair of rear outer members 42 overlap both end portions of the rear inner member 41. In this embodiment, the inner dimension of the tubular portion 42b of the rear outer member 42 is larger than the outer dimension of the rear inner member 41. The left end portion of the rear inner member 41 is inserted into the rear outer member 42 located on the left side. The right end portion of the rear inner member 41 is inserted into the rear outer member 42 located on the right side. The pair of rear outer members 42 are slidable in the left-right direction X relative to the rear inner member 41.

[0027] The rear frame 14 is disposed at the rear of the recess 103. The rear frame 14 is supported by a pair of protrusions 104. A rear bracket 18 is attached to the bottom 42a of each rear outer member 42. The rear bracket 18 is disposed along the inner surface 103b of the recess 103.

[0028] As shown in FIG. 3 , the pair of front support parts 15 extend from the front inner member 31 in a direction perpendicular to the left-right direction X. The pair of front support parts 15 are arranged side by side at an interval in the left-right direction X. The pair of front support parts 15 are integrated with the front inner member 31. Therefore, the pair of front support parts 15 can rotate together with the front inner member 31 around the pair of front outer members 32 as an axis.

[0029] The pair of rear support portions 16 protrude upward from the rear frame 14 in the up-down direction Z. The pair of rear support portions 16 are arranged side by side with a gap therebetween in the left-right direction X. The gap between the rear support portions 16 is the same as the gap between the front support portions 15.

[0030] As shown in the enlarged view of FIG. 5, the rear support portion 16 has a lower member 61 and an upper member 62. The lower member 61 protrudes upward from the rear frame 14. In this embodiment, the lower member 61 protrudes upward from the upper surface of the rear inner member 41. The lower member 61 is integrated with the rear frame 14. In this embodiment, the lower member 61 has a rectangular cylindrical shape. The lower member 61 has a plurality of through holes 61a. The plurality of through holes 61a are aligned in the vertical direction Z.

[0031] The upper member 62 of this embodiment has a holding portion 63 , a rotation shaft 64 , and a roller 65 . The holding portion 63 has a rectangular cylindrical shape. The holding portion 63 overlaps the lower member 61. Therefore, the upper member 62 overlaps the lower member 61. In this embodiment, the inner dimensions of the holding portion 63 are larger than the outer dimensions of the lower member 61. The lower member 61 is inserted into the holding portion 63. The upper member 62 is slidable in the vertical direction Z relative to the lower member 61. The holding portion 63 has a plurality of through holes 62a. The plurality of through holes 62a are aligned in the vertical direction Z.

[0032] The lower member 61 and the upper member 62 are fixed together by a bolt B inserted through the through holes 61a, 62a and a nut N threaded onto the bolt B. As described above, the lower member 61 and the upper member 62 each have a plurality of through holes 61a, 62a. Therefore, by combining the through hole 61a of the lower member 61 with the through hole 62a of the upper member 62, the lower member 61 and the upper member 62 can be fixed together with a desired amount of overlap. This allows the lower member 61 and the upper member 62 to be fixed together with the upper member 62 positioned at a desired height.

[0033] The rotation shaft 64 extends along the left-right direction X. The rotation shaft 64 is rotatably supported by the holding portion 63. The roller 65 is cylindrical. The rotation shaft 64 is inserted into the roller 65. The axis of the roller 65 coincides with the axis of the rotation shaft 64. The roller 65 is fixed to the rotation shaft 64. The roller 65 rotates integrally with the rotation shaft 64.

[0034] The rear support portion 16 of this embodiment has a spacer 66. The spacer 66 is rectangular tubular. The inner dimensions of the spacer 66 are approximately the same as the inner dimensions of the upper member 62. Therefore, the inner dimensions of the spacer 66 are larger than the outer dimensions of the lower member 61. The lower member 61 penetrates the spacer 66. The spacer 66 is interposed between the rear inner member 41 and the upper member 62 of the rear frame 14. The spacer 66 supports the upper member 62.

[0035] As shown in FIG. 3 , deck board 11 of this embodiment has a rectangular board main body 21 and a pair of square pillar-shaped rail members 22. Board main body 21 has a handle 21a at its rear end. The pair of rail members 22 are provided on the underside of board main body 21. The pair of rail members 22 are integrated with board main body 21. The pair of rail members 22 extend in a direction perpendicular to the left-right direction X. The pair of rail members 22 are aligned at an interval in the left-right direction X. The interval between rail members 22 is the same as the interval between front support portions 15. Rail member 22 has rail hole 22a. Rail hole 22a extends along the longitudinal direction of rail member 22. In other words, rail hole 22a extends in a direction perpendicular to the left-right direction X.

[0036] As shown in Figures 6 and 7, the pair of front support portions 15 are inserted into the pair of rail holes 22a. Therefore, the deck board 11 has a pair of rail holes 22a through which the pair of front support portions 15 are inserted. The deck board 11 is supported by the pair of front support portions 15. When the pair of front support portions 15 are inserted into the rail holes 22a, the deck board 11 can rotate together with the pair of front support portions 15 and the front inner member 31 around the axis of the pair of front outer members 32. Furthermore, the deck board 11 is supported by the pair of rear support portions 16 by being placed on each of the upper members 62. In this embodiment, the deck board 11 is supported by the pair of rear support portions 16 by being placed on the rollers 65 of each of the upper members 62.

[0037] The deck board 11 is slidable in the front-to-rear direction Y relative to the pair of front support portions 15. Therefore, the deck board 11 is slidable in the front-to-rear direction Y relative to the support frame 12. When the deck board 11 slides rearward relative to the support frame 12, the insertion amount of the front support portions 15 into the rail holes 22a decreases. On the other hand, when the deck board 11 slides forward relative to the support frame 12, the insertion amount of the front support portions 15 into the rail holes 22a increases. In this embodiment, the rollers 65 on which the deck board 11 is placed rotate as the deck board 11 slides in the front-to-rear direction Y. When the deck board 11 slides forward, the rollers 65 roll forward. When the deck board 11 slides rearward, the rollers 65 roll backward.

[0038] <Opening or closing of recesses> The deck board 11 opens or closes the recess 103 by sliding in the front-to-rear direction Y relative to the support frame 12 or by rotating about the front frame 13. As shown by the two-dot chain line in Figures 6 and 7, when the deck board 11 covers the opening of the recess 103, the recess 103 is closed. The deck board 11 is in a horizontal state. On the other hand, as shown by the solid line in Figures 6 and 7, when the deck board 11 does not cover the opening of the recess 103, the recess 103 is open.

[0039] As shown in Figure 6, when sliding deck board 11 to open the closed recess 103, the operator operating vehicle deck device 10 holds handle 21a and slides deck board 11 rearward. This causes deck board 11 to move rearward relative to support frame 12. As a result, as shown by the solid line in Figure 6, the opening of recess 103 is no longer covered by deck board 11, and therefore recess 103 is opened.

[0040] On the other hand, when closing an open recess 103, the operator holds handle 21a and slides deck board 11 forward. This causes deck board 11 to move forward relative to support frame 12. As a result, the opening of recess 103 is covered by deck board 11, as shown by the two-dot chain line in FIG. 6, and therefore recess 103 is closed.

[0041] The operator can adjust the opening width of recess 103 in the front-rear direction Y by adjusting the amount of sliding of deck board 11. As shown in Figure 7, when rotating the deck board 11 to open the closed recessed portion 103, the operator grasps the handle 21a and lifts the deck board 11. Then, both end portions of the front inner member 31 slide circumferentially relative to the pair of front outer members 32, causing the deck board 11 to rotate together with the pair of front support portions 15 and the front inner member 31 about the axis of the pair of front outer members 32. As a result, as shown by the solid line in Figure 7, the opening of the recessed portion 103 is no longer covered by the deck board 11, and the recessed portion 103 is therefore exposed. At this time, the deck board 11 is not supported by the pair of rear support portions 16.

[0042] On the other hand, when closing an open recess 103, the operator holds handle 21a and lowers deck board 11. As a result, both end portions of front inner member 31 slide circumferentially relative to the pair of front outer members 32, causing deck board 11 to rotate together with the pair of front support portions 15 and front inner member 31 about the axis of the pair of front outer members 32. As a result, as shown by the two-dot chain line in FIG. 7 , the opening of recess 103 is covered by deck board 11, and recess 103 is closed.

[0043] [Operation of this embodiment] The operation of this embodiment will be described. The front frame 13 has a front inner member 31 and a pair of front outer members 32 that are slidable in the left-right direction X relative to the front inner member 31. Therefore, an operator can adjust the length of the front frame 13 in the left-right direction X by sliding the pair of front outer members 32 in the left-right direction X relative to the front inner member 31. Similarly, the rear frame 14 has a rear inner member 41 and a pair of rear outer members 42 that are slidable in the left-right direction X relative to the rear inner member 41. Therefore, an operator can adjust the length of the rear frame 14 in the left-right direction X by sliding the pair of rear outer members 42 in the left-right direction X relative to the rear inner member 41.

[0044] For example, in a vehicle 100 with a wide vehicle width, the distance between the pair of hook mounting portions 106 in the left-right direction X is often long. In this case, the operator extends the length of the front frame 13 by sliding the pair of front outer members 32 relative to the front inner member 31 so as to reduce the overlapping portion between the front inner member 31 and the front outer member 32. Similarly, the operator extends the length of the rear frame 14 by sliding the pair of rear outer members 42 relative to the rear inner member 41 so as to reduce the overlapping portion between the rear inner member 41 and the rear outer member 42. This allows the vehicle deck device 10 to be applied to a vehicle 100 with a wide vehicle width.

[0045] In a vehicle 100 with a narrow vehicle width, the distance between the pair of hook mounting portions 106 in the left-right direction X is often short. In this case, the operator shortens the length of the front frame 13 by sliding the pair of front outer members 32 relative to the front inner member 31 so as to increase the overlapping portion between the front inner member 31 and the front outer member 32. Similarly, the operator shortens the length of the rear frame 14 by sliding the pair of rear outer members 42 relative to the rear inner member 41 so as to increase the overlapping portion between the rear inner member 41 and the rear outer member 42. This allows the vehicle deck device 10 to be applied to a vehicle 100 with a narrow vehicle width.

[0046] Each of the pair of rear support parts 16 has a lower member 61 and an upper member 62 that is slidable in the vertical direction Z relative to the lower member 61. Therefore, the operator can adjust the length of the rear support part 16 in the vertical direction Z by sliding the upper member 62 in the vertical direction Z relative to the lower member 61.

[0047] For example, in the case of a vehicle 100 having a deep recess 103, the operator extends the length of the rear support portion 16 by sliding the upper member 62 relative to the lower member 61 so as to reduce the overlapping portion between the lower member 61 and the upper member 62. This allows the vehicle deck device 10 to be applied to a vehicle 100 having a deep recess 103.

[0048] In the case of a vehicle 100 in which the depth of the recess 103 is shallow, the operator shortens the length of the rear support portion 16 by sliding the upper member 62 relative to the lower member 61 so as to increase the overlapping portion between the lower member 61 and the upper member 62. This allows the vehicle deck device 10 to be applied to a vehicle 100 in which the depth of the recess 103 is shallow.

[0049] [Effects of this embodiment] The effects of this embodiment will be described. (1) The support frame 12 includes a front frame 13, a rear frame 14, a pair of front support portions 15, and a pair of rear support portions 16. The front frame 13 includes a cylindrical front inner member 31 extending in the left-right direction X and a pair of front outer members 32 attached to the vehicle 100 and overlapping both ends of the front inner member 31. The rear frame 14 includes a cylindrical rear inner member 41 extending in the left-right direction X and a pair of rear outer members 42 overlapping both ends of the rear inner member 41. The front frame 13 is disposed outside the recess 103. The rear frame 14 is disposed within the recess 103. The front support portions 15 extend from the front inner member 31 in a direction perpendicular to the left-right direction X. The rear support portions 16 include a cylindrical lower member 61 protruding upward in the up-down direction Z from the rear frame 14 and an upper member 62 overlapping the lower member 61 and on which the deck board 11 is placed. Deck board 11 has a pair of rail holes 22a through which a pair of front support portions 15 are inserted.

[0050] The deck board 11 is slidable in the front-to-rear direction Y relative to the pair of front support parts 15. Therefore, the deck board 11 can open or close the recessed part 103 by sliding in the front-to-rear direction Y relative to the pair of front support parts 15. Furthermore, both end parts of the front inner member 31 are slidable in the circumferential direction relative to the pair of front outer members 32. Therefore, the deck board 11 can open or close the recessed part 103 by rotating together with the pair of front support parts 15 and the front inner member 31 about the pair of front outer members 32 as an axis.

[0051] The pair of front outer members 32 are slidable in the left-right direction X relative to the front inner member 31. Therefore, the length of the front frame 13 in the left-right direction X can be adjusted by sliding the pair of front outer members 32 in the left-right direction X relative to the front inner member 31. Furthermore, the pair of rear outer members 42 are slidable in the left-right direction X relative to the rear inner member 41. Therefore, the length of the rear frame 14 in the left-right direction X can be adjusted by sliding the pair of rear outer members 42 in the left-right direction X relative to the rear inner member 41. Therefore, the vehicle deck device 10 can be used for a variety of vehicle types with different vehicle widths.

[0052] Furthermore, the upper member 62 is slidable in the vertical direction Z relative to the lower member 61. Therefore, the length of the rear support portion 16 in the vertical direction Z can be adjusted by sliding the upper member 62 in the vertical direction Z relative to the lower member 61. Therefore, the vehicle deck device 10 can be adapted to a variety of vehicle models with different depths of the recessed portion 103. Therefore, a vehicle deck device 10 with excellent versatility can be provided.

[0053] (2) The following configuration, for example, can also be considered as a configuration for opening or closing the recessed portion 103 by the deck board 11 sliding in the fore-and-aft direction Y relative to the support frame 12 or pivoting about the front frame 13. The support frame 12 is made up of a rectangular first frame component that supports the deck board 11, and a rectangular second frame component that is attached to the vehicle 100. The first and second frame components are configured so that the first frame component is slidable in the fore-and-aft direction Y relative to the second frame component. The deck board 11 is attached via a hinge to a portion of the first frame component that extends in the left-right direction X and is located on the front side. In this case, the deck board 11 can open or close the recessed portion 103 by sliding together with the first frame component in the fore-and-aft direction Y relative to the second frame component. Furthermore, the deck board 11 can open or close the recessed portion 103 by pivoting, via the hinge, relative to a portion of the first frame component that extends in the left-and-right direction X and is located on the front side. However, this configuration requires a first frame structure and hinges.

[0054] In contrast, in front frame 13 of this embodiment, both end portions of front inner member 31 are slidable in the circumferential direction relative to the pair of front outer members 32. In other words, front frame 13 has a configuration that allows deck board 11 to rotate. Therefore, the hinges configured as described above are not required. Furthermore, deck board 11 has rail holes 22a. In other words, deck board 11 has part of the configuration that allows deck board 11 to slide. Therefore, the first frame component configured as described above is not required.

[0055] (3) Upper member 62 of rear support section 16 of this embodiment has a rotation shaft 64 that extends in the left-right direction X, and rollers 65 on which deck board 11 is placed and which rotate integrally with rotation shaft 64. With this configuration, rollers 65 rotate as deck board 11 slides in the front-rear direction Y, allowing deck board 11 to slide smoothly.

[0056] (4) In this embodiment, rear support portions 16 have spacers 66 interposed between rear frame 14 and upper member 62 in the up-down direction Z. Spacers 66 support upper member 62. With this configuration, deck board 11 can be stably supported by the pair of rear support portions 16.

[0057] (5) In this embodiment, the pair of rear support parts 16 protrude from the rear inner member 41. With this configuration, the distance between the rear support parts 16 does not change even when the pair of rear outer members 42 slide in the left-right direction X relative to the rear inner member 41. This eliminates the need for the operator to adjust the distance between the rear support parts 16 in accordance with the distance between the rail members 22.

[0058] (6) In this embodiment, rear frame 14 has a rectangular tubular shape. Therefore, compared to a case where rear frame 14 has a cylindrical shape, rear frame 14 is less likely to roll in the front-to-rear direction Y. Therefore, deck board 11 can be stably supported by the pair of rear support portions 16.

[0059] [Example of change] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0060] As shown in Fig. 8 , the vehicle deck device 10 may include a stopper device 70 that can fix the position of the deck board 11 in the front-to-rear direction Y relative to the support frame 12. Specifically, the stopper device 70 includes a gas spring 71 with a locking function and a lever 72 for operating the locking function of the gas spring 71 with a locking function.

[0061] The locking gas spring 71 has a hollow cylindrical cylinder tube 73, a piston (not shown) provided within the cylinder tube 73, and a piston rod 74 extending from the piston. The cylinder tube 73 is filled with gas. The space within the cylinder tube 73 is separated into a first space and a second space by the piston. The piston is provided with a valve. When the valve is open, the first space communicates with the second space. When the valve is closed, the first space does not communicate with the second space. The piston rod 74 passes through the second space and protrudes outside the cylinder tube 73.

[0062] The cylinder tube 73 is attached to the front inner member 31. The cylinder tube 73 is located between the pair of front support parts 15 in the left-right direction X. Like the pair of front support parts 15, the cylinder tube 73 extends from the front inner member 31 in a direction perpendicular to the left-right direction X. The piston rod 74 protrudes from the cylinder tube 73 to the side opposite the front frame 13, with the cylinder tube 73 between them. The tip of the piston rod 74 is connected to a lever 72. The lever 72 is attached to the underside of the board main body 21 of the deck board 11.

[0063] When the operator grips lever 72, a valve provided on the piston opens, connecting the first space and the second space. Gas in cylinder tube 73 moves between the first and second spaces due to the pressure difference between the first and second spaces.

[0064] When the amount of protrusion of the piston rod 74 from the cylinder tube 73 is minimum, the pressure in the second space is higher than the pressure in the first space. Therefore, when the valve is opened and the first space and the second space are connected, the gas in the second space moves to the first space. As a result, the piston moves within the cylinder tube 73 so that the second space decreases and the first space increases, and the amount of protrusion of the piston rod 74 from the cylinder tube 73 increases.

[0065] When the amount of protrusion of the piston rod 74 from the cylinder tube 73 is reduced, the piston rod 74 is pressed. This causes the pressure in the first space to become higher than the pressure in the second space. Therefore, when the valve is opened and the first space and the second space are connected, the gas in the first space moves to the second space. As a result, the piston moves within the cylinder tube 73 so that the first space decreases and the second space increases, thereby reducing the amount of protrusion of the piston rod 74 from the cylinder tube 73.

[0066] On the other hand, when the operator is not gripping the lever 72, the valve provided in the piston is closed, and the first space and the second space are not in communication with each other. In this case, gas does not move between the first space and the second space, and the piston does not move within the cylinder tube 73. As a result, the amount of protrusion of the piston rod 74 from the cylinder tube 73 is fixed.

[0067] In this way, when lever 72 is operated, the locking function is released, making it possible to adjust the amount by which piston rod 74 protrudes from cylinder tube 73. Therefore, when the operator is gripping lever 72, deck board 11 is able to slide in the front-to-rear direction Y relative to support frame 12. On the other hand, when lever 72 is not operated, the locking function is activated, fixing the amount by which piston rod 74 protrudes from cylinder tube 73. Therefore, when the operator is not gripping lever 72, deck board 11 is unable to slide in the front-to-rear direction Y relative to support frame 12. In other words, the position of deck board 11 in the front-to-rear direction Y relative to support frame 12 is fixed.

[0068] By gripping lever 72, the operator can slide deck board 11 in the front-to-rear direction Y. Then, after sliding deck board 11 to the desired position, the operator releases lever 72. This allows the position of deck board 11 in the front-to-rear direction Y relative to support frame 12 to be fixed at the desired position.

[0069] The configuration of the stopper device 70 is not limited to the above configuration. As shown in FIGS. 9 to 12, the vehicle deck device 10 may have an assist mechanism 80 that assists the pivoting movement of the deck board 11.

[0070] 9 and 10 , the assist mechanism 80 is provided on the front frame 13. The assist mechanism 80 has a torsion spring 81 and a fixed member 82. A first arm 81a of the torsion spring 81 is attached to the inner surface of the bottom portion 32a of the front outer member 32. A second arm 81b, which is positioned on the opposite side of the first arm 81a of the torsion spring 81, is attached to the end face of the fixed member 82. The fixed member 82 is disposed inside the front inner member 31.

[0071] As shown in FIG. 11 , the fixed member 82 and the front inner member 31 have a spline structure. More specifically, the outer peripheral surface 82a of the fixed member 82 is star-shaped. The inner peripheral surface 31a of the front inner member 31 is star-shaped, the same shape as the outer peripheral surface 82a of the fixed member 82. The outer peripheral surface 82a of the fixed member 82 and the inner peripheral surface 31a of the front inner member 31 mesh with each other. Therefore, the fixed member 82 cannot rotate in the circumferential direction relative to the front inner member 31. As a result, the biasing force S of the torsion spring 81, which will be described later, is transmitted to the front inner member 31 via the fixed member 82. Meanwhile, the fixed member 82 is movable in the left-right direction X relative to the front inner member 31. As a result, when the front outer member 32 slides in the left-right direction X relative to the front inner member 31, the assist mechanism 80 can also move in the left-right direction X within the front inner member 31.

[0072] Note that the shapes of the outer circumferential surface 82a of the fixed member 82 and the inner circumferential surface 31a of the front inner member 31 do not have to be star-shaped as long as the fixed member 82 cannot rotate circumferentially relative to the front inner member 31 and can move in the left-right direction X relative to the front inner member 31. For example, one of the outer circumferential surface 82a of the fixed member 82 and the inner circumferential surface 31a of the front inner member 31 may have a key, and the other may have a key groove with which the key engages.

[0073] 12, the torsion spring 81 applies a biasing force S to the front inner member 31 so that the front inner member 31 rotates forward relative to the pair of front outer members 32. In other words, the torsion spring 81 applies a biasing force S to the front inner member 31 so that the direction of rotation of the front inner member 31 relative to the pair of front outer members 32 is the direction in which the deck board 11 rises. Gravity W is also acting on the deck board 11. Of the gravity W acting on the deck board 11, the component Wa in the thickness direction of the deck board 11 decreases as the deck board 11 rises.

[0074] As described above, when rotating the deck board 11 to open the closed recessed portion 103, the operator lifts the deck board 11. Then, when the deck board 11 is raised to a position where the biasing force S of the torsion spring 81 exceeds the component Wa of gravity W acting on the deck board 11 in the thickness direction of the deck board 11, the deck board 11 will then automatically rise due to the biasing force S of the torsion spring 81, even if the operator does not lift the deck board 11. In other words, the biasing force S of the torsion spring 81 assists the rotational movement of the front inner member 31 when raising the deck board 11. Thereafter, the deck board 11 is maintained in a raised state. Therefore, the recessed portion 103 can be maintained in an open state.

[0075] Conversely, when closing an open recess 103, the operator lowers the deck board 11. Then, when the deck board 11 is lowered to a position where the biasing force S of the torsion spring 81 is less than the component Wa of gravity W acting on the deck board 11 in the thickness direction of the deck board 11, the deck board 11 will then automatically descend due to the component Wa of gravity W acting on the deck board 11 in the thickness direction of the deck board 11, even if the operator does not lower the deck board 11. Thereafter, the deck board 11 is maintained in the lowered state. Therefore, the recess 103 can be maintained in a closed state.

[0076] As long as the pair of front outer members 32 are slidable in the left-right direction X relative to the front inner member 31 and both end portions of the front inner member 31 are slidable in the circumferential direction relative to the pair of front outer members 32, the configuration of the front frame 13 may be changed as appropriate.

[0077] For example, the inner diameter of the front inner member 31 may be larger than the outer diameter of the front outer member 32. In this case, the pair of front outer members 32 are inserted into the front inner member 31 from both sides. For example, the pair of front outer members 32 may be cylindrical. In this case, the pair of front outer members 32 are inserted into the front inner member 31 from both sides.

[0078] A bearing may be provided between the front inner member 31 and the front outer member 32. As long as the pair of rear outer members 42 are slidable in the left-right direction X relative to the rear inner member 41, the configuration of the rear frame 14 may be changed as appropriate.

[0079] For example, the inner dimension of the rear inner member 41 may be larger than the outer dimension of the rear outer member 42. In this case, the pair of rear outer members 42 are inserted into the rear inner member 41 from both sides. For example, the pair of rear outer members 42 may be columnar. In this case, the pair of rear outer members 42 are inserted into the rear inner member 41 from both sides.

[0080] The cross-sectional shape of the rear frame 14 does not have to be rectangular. For example, the cross-sectional shape of the rear frame 14 may be circular. The pair of rear support portions 16 may protrude from the pair of rear outer members 42 .

[0081] As long as the upper member 62 is slidable in the up-down direction Z relative to the lower member 61, the configuration of the rear support portion 16 may be changed as appropriate. For example, the inner dimensions of the lower member 61 may be larger than the outer dimensions of the upper member 62. In this case, the upper member 62 is inserted into the lower member 61. The spacer 66 is disposed inside the lower member 61. The spacer 66 may be cylindrical or columnar.

[0082] For example, the upper member 62 may be columnar. In this case, the upper member 62 is inserted into the lower member 61. The spacer 66 is disposed inside the lower member 61. The spacer 66 may be cylindrical or columnar.

[0083] The cross-sectional shape of the rear support portion 16 does not have to be rectangular. For example, the cross-sectional shape of the rear support portion 16 may be circular. The upper member 62 of the rear support portion 16 does not have to have the rotation shaft 64 and the roller 65. In other words, the upper member 62 may be a simple rectangular tube.

[0084] The rotation shaft 64 and the roller 65 may be integrally formed. The rear support portion 16 does not have to include the spacer 66 . A plurality of spacers 66 may be disposed between the rear frame 14 and the upper member 62 depending on the amount of overlap of the upper member 62 with respect to the lower member 61 , that is, depending on the height of the upper member 62 .

[0085] Instead of having a plurality of through holes 61a aligned in the vertical direction Z, the lower member 61 may have an elongated through hole 61a extending in the vertical direction Z. Similarly, instead of having a plurality of through holes 61a aligned in the vertical direction Z, the upper member 62 may have an elongated through hole 62a extending in the vertical direction Z.

[0086] The method for fixing the lower member 61 and the upper member 62 is not limited to the bolts B and nuts N. For example, the lower member 61 and the upper member 62 may be fixed by an elastically deformable protrusion protruding from one of the lower member 61 and the upper member 62 engaging with a recess or hole provided in the other of the lower member 61 and the upper member 62.

[0087] The pair of front outer members 32 may be attached directly to the vehicle 100 without using the pair of front brackets 17. In other words, the pair of front brackets 17 may be omitted. As long as deck board 11 has rail holes 22a through which a pair of front support portions 15 are inserted, the configuration of deck board 11 may be modified as appropriate.

[0088] For example, the rail member 22 may be a member having a U-shaped cross section. In this case, the rail hole 22a is defined by the lower surface of the board body 21 and the inner surface of the rail member 22. For example, deck board 11 does not have to have rail member 22. In this case, rail hole 22a is formed directly in board body 21.
