Description

[Technical Field]

[0001] The present invention relates to an in-vehicle deck unit that can be installed in the luggage compartment behind the rear seats of an automobile and can be used across the rear seats and the luggage compartment. [Background technology]

[0002] Some users of recreational vehicles (RVs) and wagons, which are ideal for outdoor activities such as mountain climbing, hiking, fishing, and car camping, have attempted to modify the trunk design to suit their preferences by requesting the manufacturer, etc. However, there are also many users who would like to easily customize the trunk to suit their preferences, without requiring major modifications that would require the manufacturer to be requested.

[0003] For such users, pre-assembled vehicle-mounted deck units and the like are also provided. One such vehicle-mounted deck unit has been proposed, in which a base is formed by assembling multiple metal pipe frames, and a sliding top plate is placed on top of the base, allowing it to be used as a simple bed (see Patent Document 1, etc.). Another has also been proposed, in which the seat back is tilted forward and a plate-shaped deck board is simply placed on top of the seat back (see Patent Document 2, etc.).

[0004] Furthermore, an in-vehicle deck unit has also been proposed in which carpet is attached to the back of the rear seat backs (see Patent Document 3, etc.). In the in-vehicle deck unit described in Patent Document 3, by tilting the rear seat backs forward, the carpet attached to the luggage compartment and the carpet attached to the back of the seat backs can be used as a flat floor surface. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7150227 [Patent Document 2] JP 2022-141523 A [Patent Document 3] Japanese Patent Application Laid-Open No. 9-164885 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the vehicle-mounted deck unit described in Patent Document 1 has a large number of parts and a complex structure, making assembly, installation, and removal difficult. Furthermore, with the vehicle-mounted deck unit described in Patent Document 2, a deck board stored separately must be carried into the vehicle and installed each time it is used, and after use, the installed deck board must be removed and carried to a storage location for storage. Therefore, if the deck board is large and heavy, the installation and removal work is difficult, and it is also difficult to secure storage space for the deck board.

[0007] Furthermore, in the vehicle-mounted deck unit described in Patent Document 3, when the seat back is tilted forward, a gap is likely to form between the carpet attached to the back of the seat back and the carpet attached to the luggage compartment. Also, because the position of the carpet attached to the back of the seat back depends on the position of the seat back, it may be difficult to align it horizontally depending on the structure of the seat back.

[0008] The present invention has been made in consideration of the above circumstances, and aims to provide an in-vehicle deck unit that can be used as a bed or the like in a fully flat position, and that is designed to be easily adjusted to a horizontal position without creating gaps or the like. [Means for solving the problem]

[0009] The vehicle-mounted deck unit of the present invention that solves the above-mentioned object comprises a luggage deck member that is attached to the floor surface of a trunk of an automobile, an extension deck member rotatably connected to the front end of the luggage deck member via a joint portion, The extension deck member is separated from the rear seat and is provided with a support member, After the seat backs of the rear seats are folded forward, the extension deck member is extended forward and supported by the support member, thereby enabling the extension deck member to be changed to a fully flat use state in which it is in a horizontal position connected horizontally to the front of the luggage deck member. Another vehicle-mounted deck unit of the present invention that solves the above-mentioned object includes a luggage deck member that is attached to the floor surface of a trunk of an automobile, an extension deck member rotatably connected to the front end of the luggage deck member via a joint portion, The extension deck member is separate from the rear seat, After the seat backs of the rear seats are folded forward, the extension deck member is deployed forward, and the extension deck member is positioned above the seat backs with a space formed between them, and is connected horizontally to the front of the luggage deck member, making it possible to change to a fully flat use state.

[0010] Here, the fully flat use state is a use state in which the luggage deck member and the extension deck member are placed in a horizontal position (flat state) and can be used as a bed space or the like.

[0011] In the vehicle-mounted deck unit of the present invention, the extension deck member is separate from the rear seats and rotatably connected to the luggage deck member. Therefore, by rotating the extension deck member to a horizontal position in front of the luggage deck member, it is possible to create a fully flat floor without creating gaps and regardless of the position of the seatbacks.

[0012] Furthermore, in the vehicle-mounted deck unit of the present invention, the only member that needs to be attached to the vehicle is the luggage deck member, which makes it easy to attach and detach from the vehicle and eliminates the need for complex assembly work.

[0013] Furthermore, after the vehicle-mounted deck unit of the present invention is installed in a vehicle, simply by rotating the extension deck member, it can be easily switched to a fully flat usage mode that can be used as a bed space, etc. Furthermore, there is no need to transport the extension deck member to the vehicle and install it, and there is no need to store the extension deck member in a separate storage location.

[0014] In the vehicle-mounted deck unit of the present invention, the extension deck member is configured by a plurality of divided plates connected to each other via joints so as to be rotatable in the front-rear direction, In the full-flat use mode, the plurality of divided plates are deployed forward and used in a horizontal position in which the plurality of divided plates are horizontally connected in front of the luggage deck member, In a normal use mode in which the extension deck member is raised diagonally rearward and placed in an inclined position along the back of the seatback, the plurality of divided plates may be folded and used in an inclined position that is lower than the height of the rear seats. Here, the normal use mode refers to a mode in which the rear seatbacks are in their normal positions and the luggage compartment can be used normally.

[0015] According to this aspect, the bed space created when the extension deck member is deployed forward can be expanded forward. Also, in the normal use aspect, by folding the plurality of divided plates and using them in an inclined position that is lower than the height of the rear seats, the problem of the extension deck member blocking the rear view while driving can be solved.

[0016] Furthermore, in the vehicle-mounted deck unit of the present invention, a pair of side cover support members are provided on the left and right sides of the luggage compartment, The side cover support member may be configured to abut against the extension deck member in the inclined position and support the extension deck member from behind.

[0017] According to this aspect, the side cover support member can cover and conceal the rear wheel house of the vehicle body, etc., which protrudes inward from the inner wall surface of the luggage compartment of the automobile, improving the aesthetic appearance and making it possible to stably support the extension deck member in an inclined position.

[0018] In addition, the side cover support member may be attached to the inner wall surface of the side of the luggage compartment to form a box-shaped storage space with an open top, and the open top may be provided with a lid portion that can be rotated forward 180 degrees via a joint portion and used as a side table.

[0019] With this configuration, the space covered by the side cover support member can be used as a storage space for tools and luggage. Also, when the extension deck member is in a horizontal position, the cover can be rotated 180 degrees and used as a side table.

[0020] In addition, a shelf board is provided that spans between the pair of left and right side cover support members, and dowels that support both ends of the shelf board are attached to the opposing inner surfaces of the side cover support members, and the shelf board may be provided with detachable or foldable legs whose height is adjustable when used as a table.

[0021] With this configuration, the shelf board can be used to improve the usability of the luggage compartment. Furthermore, by adjusting the height of the legs attached to the shelf board, it can be used as a table of optimal height, regardless of whether the user is sitting on a chair or on the floor or ground. Furthermore, the height of the legs on the left and right sides can be changed depending on the height of the installation location. Furthermore, it is also possible to remove one of the legs on the left or right side and support the edge of the shelf board on the removed side by placing it on the top surface of the luggage deck member or the like.

[0022] In addition, in the vehicle-mounted deck unit of the present invention, the extension deck member may be configured so that the inclination angle and position in the inclined posture are set to an angle and position that do not impair the reclining mechanism of the rear seat.

[0023] By adopting this configuration, it is possible to provide a comfortable ride without impairing the reclining mechanism of the rear seats during normal use.

[0024] Furthermore, in the vehicle-mounted deck unit of the present invention, the extension deck member is divided into two in the width direction, The left extension deck member and the right extension deck member may be configured so that their positions can be independently switched between the horizontal position and the inclined position.

[0025] By adopting this configuration, it becomes possible to use only one side of the rear seat as a seat, and to lay the other side flat to use as a place to store long tools or luggage.

[0026] Furthermore, in another vehicle-mounted deck unit of the present invention, the extension deck member may have a support member on its back surface that supports the extension deck member in the horizontal position and is rotatably provided via a joint portion.

[0027] By adopting this aspect, there is no need to prepare a separate support member for when the extension deck member is in a horizontal position; it is possible to support the extension deck member in a horizontal position simply by rotating the extension deck member and the support member via their respective joint parts.

[0028] In addition, in the vehicle-mounted deck unit of the present invention, a space may be provided below the luggage deck member between it and the floor of the luggage compartment, and a drawer that can be accessed from the rear of the vehicle may be provided in this space.

[0029] When such a drawer is provided, tools and luggage stored in the drawer can be taken out or stored regardless of whether the extension deck member is in a horizontal or inclined position. [Effects of the Invention]

[0030] According to the present invention, it is possible to provide an in-vehicle deck unit that can be used as a bed or the like in a fully flat state, and that is designed to be easily adjusted to a horizontal position without creating gaps or the like. [Brief explanation of the drawings]

[0032] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0033] First, the overall configuration of the vehicle-mounted deck unit 1 will be described with reference to Figures 1 to 3. Figure 1 is a perspective side view showing the vehicle-mounted deck unit 1 of the present invention installed in an automobile 2 in a normal use state. Figure 2 is a perspective plan view showing the vehicle-mounted deck unit 1 of the present invention installed in an automobile 2 in a full-flat use state, and Figure 3 is a rear view of Figure 1.

[0034] The vehicle in which the vehicle-mounted deck unit 1 of the present invention is installed is not particularly limited as long as it has a luggage compartment behind the rear seats, but in this embodiment, as shown in Figures 1 to 3, an example is shown in which the vehicle is installed in a vehicle 2 such as an RV or wagon whose rear side can be widely opened. Specifically, the vehicle-mounted deck unit 1 comprises a luggage deck member 7 attached to the floor 6 of the luggage compartment 5 of the vehicle 2, and an extension deck member 9 rotatably connected to the front end of the luggage deck member 7 via a joint J. Here, the extension deck member 9 is configured to be separate from the rear seats 3.

[0035] As shown in Figure 2, when the vehicle-mounted deck unit 1 of the present invention is used as, for example, a bed space BS, the seatback 4A of the rear seat 3 is folded forward, and then the extension deck member 9 is deployed forward +Y and used in a horizontal position connected horizontally to the forward +Y of the luggage deck member 7 (full-flat use mode). As mentioned above, the extension deck member 9 is configured separately from the rear seat 3, so a fully flat floor surface can be formed without creating a gap between the luggage deck member 7 and the extension deck member 9.

[0036] 1 and 3, when the rear seat 3 and luggage compartment 5 of the automobile 2 equipped with the vehicle-mounted deck unit 1 of this embodiment are used for their intended purpose, the extension deck member 9 is raised diagonally rearward, and then the seat back 4A of the rear seat 3 is raised and used in an inclined position along the back of the seat back 4A of the rear seat 3 (normal use mode). In other words, the vehicle-mounted deck unit 1 of this embodiment can be switched between a full-flat use mode and a normal use mode.

[0037] The extension deck member 9 of this embodiment is composed of, for example, two divided plates 11, 13 that are connected so as to be rotatable in the front-to-rear direction Y. A support member 15 that supports the horizontal position of the extension deck member 9 when it is deployed is rotatably provided via a joint J at an appropriate position on the rear surface of the divided plate 11 on the front +Y side.

[0038] Furthermore, in this embodiment, a pair of left and right side cover support members 17L, 17R are provided on the sides of the luggage compartment 5 of the automobile 2. These side cover support members 17L, 17R cover and conceal the rear wheel housings and the like that protrude inward from the inner wall surfaces of the sides of the luggage compartment 5. The front surfaces of the side cover support members 17L, 17R are provided in an inclined position so as to function as support surfaces 18 that abut against the extension deck member 9 in an inclined position and support the extension deck member 9 from the rear -Y direction. In other words, the side cover support members 17L, 17R abut against the extension deck member 9 in an inclined position and support the extension deck member 9 from the rear.

[0039] Next, the specific configuration of each component of the vehicle-mounted deck unit 1 will be described with reference to Figures 4 to 7. Figure 4 is a side view showing the vehicle-mounted deck unit 1 when the extension deck member 9 is in a horizontal position, and Figure 5 is a side view showing the vehicle-mounted deck unit 1 when the extension deck member 9 is in an inclined position. Also, Figure 6 is a plan view of the vehicle-mounted deck unit 1 shown in Figure 4, and Figure 7 is a plan view of the vehicle-mounted deck unit 1 shown in Figure 5.

[0040] As shown in Figures 4 to 7, the luggage deck member 7 is composed of a floor board 19 provided above +Z, a frame body 21 which is a support member for the floor board 19 provided below -Z, and two drawers 23L and 23R provided on the left and right sides in the space A formed by the frame body 21.

[0041] The floor panel 19 is constructed by arranging multiple strip-shaped decorative materials in the left-right direction X on the upper surface of a base material, such as structural plywood, cut to fit the shape of the floor surface 6 of the luggage compartment 5, and attaching them to a lower frame body 21, or by fastening them together with the lower frame body 21 with screws, etc. As shown in Figure 2 and other figures, the rear ends of the decorative materials on both the left and right ends are provided with hook-shaped locking portions 20 that lock onto the rear end surfaces of side cover support members 17 (described later) to prevent the luggage deck member 7 from moving forward in the +Y direction.

[0042] Figure 8 is a bottom view showing the luggage deck member 7. As shown in Figure 8, the frame body 21 includes a bottom plate 25 that is placed on the floor surface 6 of the luggage compartment 5, and three frame members 22L, 22M, and 22R that connect the floor plate 19 and the bottom plate 25 to form a space A of a predetermined height between them. A height adjustment member 27 is provided on the underside of the bottom plate 25 as needed to accommodate unevenness in the floor surface 6 of the luggage compartment 5, and rectangular notches 29 (for example, two on the left and right in Figure 8) are provided at appropriate positions on the bottom plate 25 to avoid protruding obstacles such as a battery protruding from the floor surface 6 of the luggage compartment 5.

[0043] As shown in Figures 4 to 7, extension deck member 9 includes a front divided plate 11 located forward +Y when in the unfolded state, a rear divided plate 13 located rear -Y, and a support member 15 provided on the back surface of front divided plate 11. Similar to floor panel 19 of luggage deck member 7, two divided plates 11, 13 are constructed by arranging multiple strip-shaped decorative materials in the left-right direction X on the upper surface of a structural plywood base material cut to fit the size of the installation space for rear seat 3, and then attaching or screwing them in place. In addition, support posts 31 and the like are provided appropriately on floor surface 6 of installation space for rear seat 3 or luggage compartment 5 to accommodate unevenness in floor surface 6 and to adjust the level with respect to luggage deck member 7.

[0044] 4 and 6, when the vehicle-mounted deck unit 1 is used as a bed space BS or the like, the two divided plates 11, 13 are unfolded forward +Y, and the rear divided plate 13 and the front divided plate 11 are connected to each other in a horizontal position in the forward +Y direction of the luggage deck member 7. Furthermore, the support member 15 is raised from the back surface of the front divided plate 11, and used with its end face abutting against the floor surface 6 of the installation space for the rear seat 3 (full-flat use mode).

[0045] 4, in this embodiment, a plate- or block-shaped front reinforcing member 52 extending in the width direction is provided on the underside of the connecting portion (the rear side of joint portion J) of the divided plates 11, 13 in the unfolded state. This front reinforcing member 52 is attached to the rear divided plate 13 (see FIG. 5, etc.). In the fully flat use mode, the front reinforcing member 52 is placed on the seat back 4A, and a small space is formed between the divided plates 11, 13 and the seat back 4A.

[0046] In this embodiment, the front reinforcing member 52 reinforces the connecting portion of the divided plates 11, 13, and the space between the divided plates 11, 13 and the seat back 4A makes it easy to maintain the two divided plates 11, 13 in a horizontal position regardless of the position of the seat back 4A (for example, whether the front is tilted higher). When the extension deck member 9 is configured from a single plate, it may be supported only by the support member 15. Even in this case, it is preferable to configure the extension deck member 9 so that a space is formed between the extension deck member 9 and the seat back 4A so that it is not affected by the position of the seat back 4A. Even when the extension deck member 9 is configured from a single plate, a reinforcing member, cushioning material, or the like to be placed on the seat back 4A may be provided on the extension deck member 9.

[0047] Furthermore, in this embodiment, a rear reinforcing member 53 extending in the width direction is also provided on the underside (rear side of joint J) of the connecting portion between the floor panel 19 and the divided plate 13 in order to reinforce the connecting portion between the floor panel 19 and the divided plate 13. This rear reinforcing member 53 is attached to the floor panel 19 (see FIG. 5).

[0048] 5 and 7, when the rear seat 3 and luggage compartment 5 of the automobile 2 are used for their intended purpose, the two divided plates 11, 13 and the support member 15 are folded and used in an inclined position that is lower than the height of the seat back 4A of the rear seat 3 (normal use mode). Here, the inclination angle θ and position of the extension deck member 9 when in the inclined position are set to an angle and position that do not impair the reclining mechanism of the seat back 4A of the rear seat 3.

[0049] Furthermore, in this embodiment, the extension deck member 9 is divided into two in the width direction X, and the left-side extension deck member 9L and the right-side extension deck member 9R are configured to be able to independently switch their positions between a horizontal position and an inclined position. Accordingly, the front reinforcing member 52 and the support member 15 are also divided into two, and the support member 15L attached to the left-side extension deck member 9L and the support member 15R attached to the right-side extension deck member 9R are configured to be able to independently rotate.

[0050] The left and right support members 15L, 15R are rectangular, flat-plate-shaped members. The height of the support members 15L, 15R is set so that the extension deck members 9L, 9R are horizontal when unfolded. The width of the support members 15L, 15R is set smaller than the width of the extension deck members 9L, 9R to which they are attached so that they do not abut against the support surfaces 18 of the side cover support members 17L, 17R (described below) when folded. As shown in FIGS. 4 and 5 , magnetic catches 35, which also serve as legs that abut against the floor 6, are attached to the end faces of the left and right support members 15L, 15R, and metal pieces 37 that are attracted to the magnetic catches 35 when folded are attached to the corresponding positions of the front divided plate 11.

[0051] Fig. 9 is a perspective view showing the side cover support member 17R with the lid closed, and Fig. 10 is a perspective view showing the side cover support member 17R when the lid 39 is open and used as a side table. As shown in Figs. 9 and 10, the side cover support members 17L, 17R are members that form a box-shaped storage space B with an open top by being attached to the inner wall surface of the side of the luggage compartment 5. The open top is provided with a lid 39 that can be rotated 180 degrees forward +Y via a joint J and used as a side table.

[0052] The side cover support members 17L, 17R comprise an inner panel 41 having multiple strip-shaped decorative materials arranged in the front-to-back direction Y and attached to the surface of a base material made of, for example, structural plywood, a front panel 43 that closes the front of the inner panel 41, and a lid portion 39.

[0053] In this embodiment, a mounting frame 45 is provided on the back surface of the base material side of the inner panel 41, which is attached to the inner wall surface of the trunk 5 of the automobile 2. The side cover support members 17L, 17R are attached to the inner wall surface of the trunk 5 using this mounting frame 45 by screwing them to the inner wall surface of the trunk 5 at only one location using a thumbscrew or the like. The mounting structure of the side cover support members 17L, 17R is not particularly limited, but using a mode in which they are screwed to only one location using a thumbscrew, as in this embodiment, makes attachment and detachment extremely easy. In addition, two dowels 47 are attached to each of the opposing inner surfaces of the side cover support members 17L, 17R at a predetermined height position.

[0054] Figure 11 is a perspective view showing the state in which shelf boards 49 are attached to the side cover support members 17L, 17R. As shown in Figure 11, the shelf boards 49 are configured so that they can be attached by supporting both ends with dowels 47. Like the floor boards 19 of the luggage deck member 7, the shelf boards 49 are configured by affixing strips of decorative material in the front-to-rear direction Y to the top surface of a base material made of, for example, structural plywood. In addition, the shelf boards 49 are provided with removable or foldable legs 51 that can be used when using the shelf boards 49 as a table and have adjustable heights.

[0055] In addition, if abnormal noise or rattle occurs due to vibrations during driving when the extension deck member 9 is folded into an inclined position, it is possible to prevent rattle by attaching rubber material or hook-and-loop fasteners to either or both of the support surface 18 of the side cover support member 17 and the opposing surface of the extension deck member 9, or by attaching metal fittings to connect the two. In addition, it is also possible to prevent rattle of the extension deck member 9 in an inclined position by biasing the shelf board 49 attached between the left and right side cover support members 17L, 17R forward in the +Y direction with a spring or the like.

[0056] Next, the procedure for installing the vehicle-mounted deck unit 1 will be described.

[0057] When installing the vehicle-mounted deck unit 1 of this embodiment in an automobile 2, the floor material of the luggage compartment 5 of the automobile 2 is removed as necessary, and the support posts 31 are installed at predetermined positions on the exposed floor surface 6, as shown in Figure 9 etc. Next, the left and right side cover support members 17L, 17R are set in predetermined positions, the lid 39 is opened, and the mounting frame 45 is fixed to the inner wall surface of the luggage compartment 5 with thumb screws (not shown).

[0058] Thereafter, the luggage deck member 7 is inserted from the rear of the automobile 2 until the locking portions 20 of the floor panel 19 abut against the rear end surfaces of the side cover support members 17L, 17R. Then, the luggage deck member 7 is fixed in place using screws or the like as necessary. If the extension deck member 9 is already attached to the luggage deck member 7, the installation of the vehicle-mounted deck unit 1 is complete at this point. However, if the extension deck member 9 is removed and the luggage deck member 7 is attached first, the two are connected using the joint portion J.

[0059] When using the shelf board 49, the dowels 47 attached to the left and right side cover support members 17L, 17R are used to attach the shelf board 49 so that both ends of the shelf board 49 are supported by the dowels 47. In this state, the legs 51 are not needed, so as shown in Figure 11, the legs 51 are removed and stored in the drawer 23 or the like.

[0060] Next, the procedure for switching the posture of the extension deck member 9 will be described.

[0061] When using the vehicle-mounted deck unit 1 as a bed space BS or the like (in the fully flat use mode), as shown in FIG. 4, first, the seatback 4A of the rear seat 3 is folded forward in the +Y direction so that it overlaps the seat cushion 4B. Next, the two divided plates 11 and 13 and the support member 15, which are folded in a rearwardly tilted position, are unfolded forward in the +Y direction so that they are connected flatly and horizontally in front of the luggage deck member 7. This forms a large, fully flat bed space BS that is long in the fore-and-aft direction Y, and its horizontal position is supported by the support member 15 and the front reinforcing member 52 placed on the seatback 4A. As described above, the extension deck member 9 is configured separately from the rear seat 3, so no gaps or the like are created. Furthermore, because a space is formed between the divided plates 11 and 13 and the seatback 4A, it is easy to adjust the extension deck member 9 to a horizontal position regardless of the position of the seatback 4A.

[0062] When using the rear seats and luggage compartment for their intended purpose (normal use), the extension deck member 9 is folded from its horizontal position and rotated diagonally rearward to assume an inclined position, as shown in Figure 5. Here, the inclination angle θ and position of the extension deck member 9 in the inclined position are regulated by the support surfaces 18 of the left and right side cover support members 17 positioned rearward -Y. Next, by raising the seatback 4A of the rear seats 3 and reclining it to the desired angle, the rear seats 3 and luggage compartment 5 can be used for their intended purpose.

[0063] Next, an example of using shelf board 49 as a table will be described. Shelf board 49 can be used as a table by attaching legs 51 to it, in addition to being used as shelf board 49. Fig. 12 is a perspective view showing an example of using shelf board 49 as a table, and Fig. 13 is a perspective view showing another example of using shelf board 49 as a table.

[0064] As shown in FIG. 12 , a leg 51 extending from the ground level GL to the top surface of the luggage deck member 7 can be attached to one end of the shelf 49, and the other end of the shelf 49 can be placed on the top surface of the luggage deck member 7 or on the left-side drawer 23L when it is pulled out. In this configuration, the shelf 49 can be used as a table for eating or cooking. To prevent the shelf 49 from sliding off the top surface of the luggage deck member 7, it is possible to fasten it with a thumbscrew or provide an engaging means for engaging the two. While FIG. 12 shows the leg 51 made of a combination of square timber and round timber, the shape of the leg 51 is not particularly limited and it may be made of round timber connected to round timber or square timber connected to square timber. Although not shown, it is also possible to extend the floor surface rearward (outward) by pulling out the left and right drawers 23L and placing the shelf 49 on them.

[0065] Furthermore, as shown in Fig. 13, it is also possible to change the height of the legs 51 attached to both shelf boards 49. Fig. 13 shows an example of use in which the left extension deck member 9L is in a horizontal position and the right extension deck member 9R is in an inclined position, and the shelf board 49 is used as a work desk by a user sitting in the rear seat 3 of the inclined position. In this case, in order to maintain the horizontal position of the shelf board 49, the left leg 51L is shorter than the height of the right leg 51R by the height of the extension deck member 9 in the horizontal position.

[0066] In this way, according to the vehicle-mounted deck unit 1 of the present invention, it is possible to provide a vehicle-mounted deck unit that can be used in a fully flat state so that it can be used as a bed, etc., and is designed to be easily adjusted to a horizontal state without creating gaps, etc.

[0067] Also, since there are no parts that need to be stored in a separate location, there is no need to secure a storage space for parts or transport them. Furthermore, the bed space formed by deploying the extension deck member 9 has a completely flat structure, making it possible to secure a large space that can support the entire body, for example. Furthermore, there is plenty of storage space for tools and luggage, and the stored tools and luggage can be easily taken in and out, making it possible to enjoy an easy-to-use and comfortable life using the on-board deck unit.

[0068] The vehicle-mounted deck unit 1 of the present invention is not limited to the configuration described in the above-described embodiment, and various modifications can be made within the scope of the claims. For example, in the above-described embodiment, the extension deck member 9 is composed of two divided plates 11 and 13. However, the extension deck member 9 may be composed of a single plate or three or more divided plates. Furthermore, the vehicle-mounted deck unit 1 of the present invention is not limited to the wooden plate material described in the above-described embodiment, but can also be made using a resin material such as FRP (fiber-reinforced plastic) or a metal material. Furthermore, the support member 15 is not limited to a plate material, but can also be made of a pillar material, a metal frame, or the like. Furthermore, in the above-described embodiment, the extension deck member 9 is described as being divided into two in the width direction X. However, the extension deck member 9 may be an integral part, or may be divided into three or more parts in the width direction X. Furthermore, in the above-described embodiment, an example was described in which the support member 15 was rotatably attached to the front +Y divided plate 11 via the joint part J, but the support member 15 may also be detachably attached to the front +Y divided plate 11. (Appendix 1) Other vehicle-mounted deck units are: a luggage deck member to be attached to the floor of a luggage compartment of an automobile; an extension deck member rotatably connected to the front end of the luggage deck member via a joint portion, The extension deck member is separate from the rear seat, a full-flat use mode in which the seat backs of the rear seats are folded forward, and then the extension deck member is deployed forward to assume a horizontal position in which the extension deck member is connected horizontally to the front of the luggage deck member; The extension deck member can be raised diagonally backward and placed in an inclined position along the back of the seat back during normal use. (Appendix 2) Another vehicle-mounted deck unit is a luggage deck member that is attached to the floor of the luggage compartment of a vehicle, an extension deck member rotatably connected to the front end of the luggage deck member via a joint portion, The extension deck member is separate from the rear seat, a full-flat use mode in which the seat backs of the rear seats are folded forward, and then the extension deck member is deployed forward to be positioned above the entire seat backs and horizontally connected to the front of the luggage deck member; The extension deck member can be raised diagonally backward and placed in an inclined position along the back of the seat back during normal use. (Appendix 3) Another vehicle-mounted deck unit includes a luggage deck member having a floor material that covers the floor surface of the luggage compartment of the automobile, an extension deck member rotatably connected to the front end of the luggage deck member via a joint portion, The extension deck member is separate from the rear seat, a full-flat use mode in which the seat backs of the rear seats are folded forward, and then the extension deck member is deployed forward to assume a horizontal position in which the extension deck member is connected horizontally to the front of the luggage deck member; a normal use state in which the extension deck member is raised obliquely rearward and placed in an inclined position along the back surface of the seat back; The fully flat use mode is characterized in that the floor material and the extension deck member can be used as a bed.
