Summary of the Invention

Problems to be Solved by the Invention

[0005] In the case of the in-vehicle bed described in Patent Document 1, there is a problem that the operation of connecting the coupling frame and the front base frame to the central base frame is complicated. In addition, there is also a problem that the floor surface is restricted by arranging a pair of legs of the front base frame on the floor surface.

[0006] Note that such problems are not limited to in-vehicle beds and are generally common in in-vehicle support devices having a support surface that supports an object from below.

Means for Solving the Problems

[0007] Each aspect of the in-vehicle support device for solving the above problems will be described. [Aspect 1] A fixed frame fixed to the floor in the vehicle interior and extending along a slide direction orthogonal to the vertical direction of the vehicle, A plurality of lower rollers attached to the fixed frame at intervals in the slide direction, An upper roller attached to the fixed frame above the plurality of lower rollers, A movable frame extending along the slide direction and slidably supported along the slide direction by the plurality of lower rollers and the upper rollers, The movable frame is configured to be slidable between a first position that is on one side of the slide direction with respect to a first lower roller that is located on the most one side in the slide direction among the plurality of lower rollers and a second position that is on the other side of the slide direction with respect to the first position, and has a support surface capable of supporting an object from below. The upper roller is located on the other side of the slide direction with respect to the first lower roller. The movable frame is supported by the first lower roller and the upper roller when the movable frame is in the first position. An in-vehicle support device.

[0008] According to the same configuration, the movable frame is slidably supported between a first position and a second position by a plurality of lower rollers and upper rollers attached to the fixed frame along the sliding direction, that is, the extending direction of the movable frame. In particular, when the movable frame is in the first position, it is supported by a first lower roller located on one side in the sliding direction and an upper roller located on the other side in the sliding direction than the first lower roller. Thereby, when a downward load acts on the movable frame, the portion of the movable frame where the load acts becomes the effort point, the first lower roller becomes the fulcrum, and the upper roller becomes the point of action. In this way, by sliding the movable frame to the first position, the position of the support surface for supporting the object from below can be changed to one side in the sliding direction from the position of the first lower roller. Therefore, the position of the support surface can be easily changed.

[0009] [Aspect 2] When the movable frame is in the first position, a first distance, which is the distance from the end of the movable frame on one side in the sliding direction to the center of the first lower roller, is shorter than a second distance, which is the distance from the center of the first lower roller to the center of the upper roller in the sliding direction. The in-vehicle support device according to Aspect 1.

[0010] According to the same configuration, the first distance, which is the distance between the effort point and the fulcrum, is shorter than the second distance, which is the distance between the fulcrum and the point of action. Therefore, even if legs for supporting the movable frame from below are not provided on the movable frame, the load-bearing capacity of the movable frame can be sufficiently increased by the lever principle. In other words, by configuring the first distance, which is the distance between the effort point and the fulcrum, to be shorter than the second distance, which is the distance between the fulcrum and the point of action, the legs of the movable frame that were necessary to increase the load-bearing capacity can be omitted. Thereby, it is possible to avoid the floor being restricted due to the legs.

[0011] [Aspect 3] The sliding direction is the longitudinal direction of the vehicle, The first position is a position in front of the first lower roller that is located at the frontmost side among the plurality of lower rollers. The second position is a position behind the second lower roller that is located at the rearmost side among the plurality of lower rollers. When the movable frame is in the first position, the movable frame is supported by the first lower roller and the upper roller. On the other hand, when the movable frame is in the second position, the movable frame is supported by the second lower roller and the upper roller. The in-vehicle support device according to aspect 2.

[0012] According to the same configuration, by sliding the movable frame to the first position at the front side, the position of the support surface can be changed to a position in front of the position of the first lower roller. Also, by sliding the movable frame to the second position at the rear side, the position of the support surface can be changed to a position behind the position of the second lower roller. Therefore, the position of the support surface can be easily changed back and forth.

[0013] [Aspect 4] On the rear surface of the vehicle, an opening that communicates the inside and outside of the vehicle and a back door that opens and closes the opening are provided. The second position is a position behind the opening. The in-vehicle support device according to aspect 3.

[0014] According to the same configuration, the movable frame can be slid to the second position behind the opening on the rear surface of the vehicle. Thereby, the support surface of the movable frame can be used outside the vehicle.

[0015] [Aspect 5] A pair of the fixed frame, the plurality of lower rollers, and the upper roller are provided at intervals in the vehicle width direction. The movable frame includes a lower movable frame that extends along the front-rear direction and is supported by a plurality of the lower rollers and the upper rollers, an upper movable frame that extends along the front-rear direction and is located above the upper rollers, a connecting frame that connects the lower movable frame and the upper movable frame, and an upper connecting frame that connects the upper movable frames. The support surface is constituted by the upper surfaces of a pair of the upper movable frames and the upper surface of the upper connecting frame. The in-vehicle support device according to Aspect 3 or Aspect 4.

[0016] According to this configuration, the upper surfaces of a pair of upper movable frames and the upper surface of the upper connecting frame constitute the support surface. Therefore, by increasing the area of the support surface, the object can be stably supported.

[0017] Further, the upper connecting frame connects the upper movable frames in the vehicle width direction that is orthogonal to the front-rear direction which is the sliding direction of the movable frame. Therefore, the user can easily perform the sliding operation by gripping and pushing / pulling the upper connecting frame.

[0018] [Aspect 6] When the connecting frame is a movable-side connecting frame, The fixed frame includes a lower fixed frame that extends in the front-rear direction and to which a plurality of the lower rollers are attached, an upper fixed frame that extends along the front-rear direction and is located above the upper rollers, and a fixed-side connecting frame that connects the lower fixed frame and the upper fixed frame. The upper surface of the upper fixed frame is located on the same plane as the support surface. The object is a bed mat. The in-vehicle support device according to Aspect 5.

[0019] According to the same structure, a bed mat can be placed on the upper surfaces of a pair of upper fixed frames. In addition, by sliding the movable frame back and forth with respect to the fixed frame, the bed mat can also be placed on the upper surfaces of a pair of upper movable frames and the upper connecting frame. In particular, since the upper surface of the upper fixed frame is located on the same plane as the support surface, it is difficult for a step to occur on the bed mat. Therefore, it is possible to easily expand the bed space back and forth while maintaining a comfortable state.

Effect of the Invention

[0020] According to the in-vehicle support device of the present invention, the usability can be improved.

[0035] Specifically, as shown in FIGS. 1 and 3, the plurality of lower rollers 30 are attached to the inner side surface of the lower fixed frame 22 in the vehicle width direction W at equal intervals. The plurality of lower rollers 30 include a first lower roller 31 located at the foremost side, a second lower roller 32 located at the rearmost side, and an intermediate lower roller 33 located between the first lower roller 31 and the second lower roller 32.

[0036] In this embodiment, seven lower rollers 30 are provided for convenience. There are five intermediate lower rollers 33 in this embodiment. (Upper roller 40) As shown in FIGS. 1 to 3, an upper roller 40 is attached to the fixed frame 20 above the plurality of lower rollers 30. The upper roller 40 is rotatably supported by the fixed frame 20 about an axis extending along the vehicle width direction W. An annular convex portion is provided at the central portion in the axial direction of the upper roller 40.

[0037] Specifically, two upper rollers 40 are arranged in parallel in the front - rear direction on the inner side surface in the vehicle width direction W of the mounting frame 28. That is, the two upper rollers 40 are provided in parallel below the upper fixed frame 23 and at the central position in the front - rear direction L of the lower fixed frame 22.

[0038] (Movable frame 50) As shown in FIGS. 1 to 4, the movable frame 50 extends along the front - rear direction L and is slidably supported along the front - rear direction L by a plurality of lower rollers 30 and upper rollers 40.

[0039] As shown in FIGS. 1 and 3, the movable frame 50 includes a lower movable frame 51, an upper movable frame 52, a movable - side connecting frame 53, and an upper connecting frame 54. The lower movable frame 51 extends along the front - rear direction L and is supported by a plurality of lower rollers 30 and upper rollers 40.

[0040] Specifically, on the lower surface of the lower movable frame 51, a concave groove for accommodating the annular protrusion of the lower roller 30 is provided along the front - rear direction L. On the upper surface of the lower movable frame 51, a concave groove for accommodating the annular protrusion of the upper roller 40 is provided along the front - rear direction L.

[0041] At the front end and the rear end of the lower movable frame 51, a movable - side connecting frame 53 extending along the vertical direction Z is connected. The upper movable frame 52 is connected to the front - rear movable - side connecting frames 53. The upper movable frame 52 extends along the front - rear direction L. A part of the upper movable frame 52 behind the front end is connected to the front - side movable - side connecting frame 53. That is, the front end of the upper movable frame 52 is located in front of the front - side movable - side connecting frame 53. The rear end of the upper movable frame 52 is connected to the rear - side movable - side connecting frame 53.

[0042] As shown in FIGS. 1 to 4, the movable - side connecting frame 53 is connected to the inner side surfaces in the vehicle width direction W of the lower movable frame 51 and the upper movable frame 52. The upper movable frame 52 is located above the upper roller 40.

[0043] The upper connecting frame 54 connects the front movable-side connecting frames 53 to each other. The upper connecting frame 54 extends along the vehicle width direction W. As shown in FIGS. 2 and 3, when the movable frame 50 is in the neutral position, in the front-rear direction L, the front end and the rear end of the lower movable frame 51 coincide with the front end and the rear end of the lower fixed frame 22, respectively.

[0044] The movable frame 50 is configured to be slidable between a first position (see FIGS. 5 and 6) which is a position in front of the first lower roller 31 and a second position (see FIGS. 7 and 8) which is a position behind the second lower roller 32.

[0045] As shown in FIGS. 5 and 6, when the movable frame 50 is in the first position, the movable frame 50 is supported by the first lower roller 31 and the upper roller 40. As shown in FIG. 6, when the movable frame 50 is in the first position, a first distance L1 which is the distance from the front end of the movable frame 50 to the center of the first lower roller 31 in the front-rear direction L is shorter than a second distance L2 which is the distance from the center of the first lower roller 31 to the center of the upper roller 40 in the front-rear direction L (L1 < L2).

[0046] As shown in FIGS. 7 and 8, when the movable frame 50 is in the second position, the movable frame 50 is supported by the second lower roller 32 and the upper roller 40. As shown in FIG. 6, when the movable frame 50 is in the second position, a third distance L3 which is the distance from the rear end of the movable frame 50 to the center of the second lower roller 32 in the front-rear direction L is shorter than the second distance L2 which is the distance from the center of the second lower roller 32 to the center of the upper roller 40 in the front-rear direction L (L3 < L2).

[0047] As shown in FIGS. 5 and 6, the movable frame 50 is provided with a first stopper 56 that restricts the movable frame 50 from sliding forward from the first position by contacting the upper roller 40. The first stopper 56 is provided between the rear end of the lower movable frame 51 and the rear end of the upper movable frame 52. The first stopper 56 is configured to restrict the forward sliding of the movable frame 50 by contacting the rear upper roller 40 of the two upper rollers 40.

[0048] As shown in FIGS. 7 and 8, the movable frame 50 is provided with a second stopper 57 that restricts the movable frame 50 from sliding rearward from the second position by contacting the upper roller 40. The second stopper 57 is provided between the front end of the lower movable frame 51 and the front end of the upper movable frame 52. The second stopper 57 is configured to restrict the rearward sliding of the movable frame 50 by contacting the front upper roller 40 of the two upper rollers 40.

[0049] The first stopper 56 and the second stopper 57 preferably have a shock-absorbing member (not shown in the figure) for absorbing the impact with the upper roller 40 at the portion in contact with the upper roller 40. The shock-absorbing member is preferably a foamed material such as urethane foam or a rubber material.

[0050] As shown in FIG. 7, the second position is a position rearward of the opening 91. (Support surface 55) As shown in FIG. 9, the movable frame 50 has a support surface 55 that can support the bed mat 80, which is the object, from below. The support surface 55 is composed of the upper surfaces 52a of the pair of upper movable frames 52 and the upper surface 54a of the upper connecting frame 54.

[0051] The upper surface 23a of the upper fixed frame 23 is located on the same plane as the support surface 55. The upper surface 25a of the auxiliary frame 25 is located on the same plane as the support surface 55. As shown in FIGS. 4 and 9, one auxiliary mat 83 is fixedly supported on the upper surface 25a of each of a plurality of auxiliary frames 25 arranged on both sides in the vehicle width direction W.

[0052] The auxiliary mat 83 is substantially rectangular plate-shaped in plan view and long in the front-rear direction L. One first mat 81 is placed on a portion of the support surface 55 in front of the auxiliary frame 25. The first mat 81 is substantially rectangular plate-shaped in plan view and long in the vehicle width direction W. Both ends of the first mat 81 in the vehicle width direction W are located outside a pair of upper movable frames 52.

[0053] Two second mats 82 are placed side by side in the front-rear direction on the upper surface 23a of a pair of upper fixed frames 23. The second mat 82 is substantially rectangular plate-shaped in plan view and long in the vehicle width direction W. The second mat 82 is adjacent to the auxiliary mat 83 on both sides in the vehicle width direction W.

[0054] The thicknesses of the first mat 81, the second mat 82, and the auxiliary mat 83 are the same. As shown in FIG. 4, the first mat 81 and the two second mats 82 are stored on the first connecting frame 26 and the second connecting frame 27 in a stacked state.

[0055] Next, the operation of the present embodiment will be described. The movable frame 50 is slidably supported between a first position and a second position along the front-rear direction L by a plurality of lower rollers 30 and upper rollers 40 attached to the fixed frame 20.

[0056] As shown in FIG. 6, when the movable frame 50 is in the first position, it is supported by the first lower roller 31 located at the most front side and the upper roller 40 located at the rear side of the first lower roller 31. Thus, when a downward load acts on the movable frame 50, the portion of the movable frame 50 where the load acts becomes the effort point, the first lower roller 31 becomes the fulcrum, and the upper roller 40 becomes the point of application. In this way, by sliding the movable frame 50 to the first position, the position of the support surface 55 that supports the bed mat 80 from below can be changed to the front side of the position of the first lower roller 31 (the above is Action 1).

[0057] As shown in FIG. 8, when the movable frame 50 is in the second position, it is supported by the second lower roller 32 located at the most rear side and the upper roller 40 located at the front side of the first lower roller 31. Thus, when a downward load acts on the movable frame 50, the portion of the movable frame 50 where the load acts becomes the effort point, the second lower roller 32 becomes the fulcrum, and the upper roller 40 becomes the point of application.

[0058] Next, the effects of the present embodiment will be described. (1) The support device 10 includes a fixed frame 20, a plurality of lower rollers 30, an upper roller 40, and a movable frame 50. The movable frame 50 is configured to be slidable between a first position that is in front of the first lower roller 31 and a second position that is behind the first position, and has a support surface 55 that can support the bed mat 80 (the first mat 81, the second mat 82) from below. The upper roller 40 is located at the rear side of the first lower roller 31. The movable frame 50 is supported by the first lower roller 31 and the upper roller 40 when the movable frame 50 is in the first position.

[0059] According to such a configuration, since the above Action 1 is achieved, the position of the support surface 55 can be easily changed. Therefore, the usability can be improved. (2) When the movable frame 50 is in the first position, a first distance L1, which is the distance from the front end of the movable frame 50 in the front-rear direction L to the center of the first lower roller 31, is shorter than a second distance L2, which is the distance from the center of the first lower roller 31 to the center of the upper roller 40 in the front-rear direction L (L1 < L2). Also, when the movable frame 50 is in the second position, a third distance L3, which is the distance from the rear end of the movable frame 50 in the front-rear direction L to the center of the second lower roller 32, is shorter than the second distance L2, which is the distance from the center of the second lower roller 32 to the center of the upper roller 40 in the front-rear direction L (L3 < L2).

[0060] According to such a configuration, the first distance L1 (the third distance L3), which is the distance between the force point and the fulcrum, becomes shorter than the second distance L2, which is the distance between the fulcrum and the point of action. For this reason, even if legs for supporting the movable frame 50 from below are not provided on the movable frame 50, the load-bearing capacity of the movable frame 50 can be sufficiently increased by the lever principle. In other words, by configuring the first distance L1, which is the distance between the force point and the fulcrum, to be shorter than the second distance L2, which is the distance between the fulcrum and the point of action, the legs of the movable frame 50 that were necessary for increasing the load-bearing capacity can be omitted. As a result, it is possible to avoid the floor 93 being restricted due to the legs.

[0061] (3) The first position is a position in front of the first lower roller 31, which is located at the frontmost side among the plurality of lower rollers 30. The second position is a position behind the second lower roller 32, which is located at the rearmost side among the plurality of lower rollers 30. The movable frame 50 is supported by the first lower roller 31 and the upper roller 40 when the movable frame 50 is in the first position, while the movable frame 50 is supported by the second lower roller 32 and the upper roller 40 when the movable frame 50 is in the second position.

[0062] According to such a configuration, by sliding the movable frame 50 to the first position on the front side, the position of the support surface 55 can be changed to a position in front of the position of the first lower roller 31. Further, by sliding the movable frame 50 to the second position on the rear side, the position of the support surface 55 can be changed to a position behind the position of the second lower roller 32. Therefore, since the position of the support surface 55 can be changed back and forth, it is easy to expand the bed space back and forth.

[0063] (4) The second position is a position behind the opening 91 on the back surface of the vehicle 90. According to such a configuration, the movable frame 50 can be slid to the second position behind the opening 91 on the back surface of the vehicle 90. Thereby, since the support surface 55 of the movable frame 50 can be used outside the vehicle, the bed space can be expanded to the outside of the vehicle with a sense of openness.

[0064] (5) The support surface 55 is constituted by the upper surfaces 52a of the pair of upper movable frames 52 and the upper surface 54a of the upper connecting frame 54. According to such a configuration, the upper surfaces 52a of the pair of upper movable frames 52 and the upper surface 54a of the upper connecting frame 54 constitute the support surface 55. For this reason, by increasing the area of the support surface 55, the bed mat 80 (the first mat 81, the second mat 82) can be stably supported.

[0065] Further, the upper connecting frame 54 connects the upper movable frames 52 to each other in the vehicle width direction W orthogonal to the front-rear direction L which is the sliding direction of the movable frame 50. For this reason, it is easy for the user to perform a sliding operation by gripping and pushing and pulling the upper connecting frame 54.

[0066] (6) The upper surface 23a of the upper fixed frame 23 is located on the same plane as the support surface 55. According to such a configuration, the bed mat 80 (second mat 82) can be placed on the upper surface 23a of the pair of upper fixed frames 23. In addition to this, by sliding the movable frame 50 back and forth with respect to the fixed frame 20, the bed mat 80 (first mat 81) can also be placed on the upper surface 52a of the pair of upper movable frames 52 and the upper surface 54a of the upper connecting frame 54. In particular, since the upper surface 23a of the upper fixed frame 23 is located on the same plane as the support surface 55, a step is less likely to occur between the first mat 81 and the second mat 82. Therefore, it is possible to easily expand the bed space back and forth while maintaining a comfortable state.

[0067] (7) The upper surface 25a of the auxiliary frame 25 is located on the same plane as the support surface 55. According to such a configuration, the bed mat 80 (auxiliary mat 83) can also be arranged on the upper surface 25a of the auxiliary frame 25. Therefore, the bed space can be expanded also in the vehicle width direction W.

[0068] <Modification Example> This embodiment can be implemented by making the following changes. This embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0069] · The number and position of the auxiliary frames 25 can be appropriately changed. · The auxiliary frame 25 can also be omitted. · The second mat 82 can be made into one sheet or three or more sheets.

[0070] · The first mat 81 can be made into two or more sheets. · The upper roller 40 can be made into one or three or more. · The lower roller 30 may be two or more, and can be made into three or five.

[0071] · The support surface 55 is not limited to supporting the bed mat 80, and may be, for example, something that supports a work top plate from below. · The second position may be a position in front of the opening 91.

[0072] · The second position can also be set as the neutral position. That is, the movable frame 50 may not be able to slide rearward from the neutral position (the second position). Also, in a configuration where the support device 10 is inverted front to back, the movable frame 50 will not be able to slide forward from the neutral position (the second position).

[0073] · The sliding direction of the movable frame 50 is not limited to the front - rear direction L. The sliding direction may be any direction orthogonal to the up - down direction Z of the vehicle 90, for example, the vehicle width direction W. In this case, the first position can be set inside the vehicle cabin, and the second position can be set outside the vehicle width direction W from the opening that opens to the side surface of the vehicle 90. Also in this case, the first position can be set outside the vehicle width direction W from the opening that opens to the side surface opposite to the above - mentioned side surface of the vehicle 90.

[0074] · Making the first distance L1 shorter than the second distance L2 is preferable for easily increasing the load - bearing capacity of the movable frame 50 based on the lever principle. However, it is also possible to make the first distance L1 the same as the second distance L2, or to make the first distance L1 longer than the second distance L2.
