Description

[Technical field]

[0001] The present disclosure relates to a storage device. [Background technology]

[0002] Patent Document 1 discloses a storage box that has a luggage carrying section that projects and retracts under the rear seat, and that becomes a deep box when the bottom of the luggage carrying section is raised.

[0003] Patent document 2 also discloses a storage box that has a rotating side wall under the seat, and a first free-standing end wall and a second free-standing end wall at both ends of the side wall that fold inward and link with the side wall. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6674080 [Patent Document 2] US Patent Application Publication No. 2017 / 0072863 Summary of the Invention [Problem to be solved by the invention]

[0005] In the structure described in Patent Document 1, the storage box cannot stand on its own, so the task of lifting the bottom requires the use of both hands.

[0006] In the configuration described in Patent Document 2, when folding the free-standing end walls of the storage box, the user needs to fold the first free-standing end wall and the second free-standing end wall inward.

[0007] The present disclosure aims to provide a storage device that is easy to use. [Means for solving the problem]

[0008] A first aspect of the present disclosure is a storage device comprising: a storage section disposed under a seat of a vehicle and on which items are placed; a first panel attached to the storage section and rotatably movable between a tilted position inclined with respect to the storage section and an upright position; a second panel attached to a side of the first panel and rotatably movable between a folded position in which it is folded with respect to the first panel and an unfolded position in which it is unfolded; a panel biasing member that biases the second panel from the folded position toward the unfolded position; and a guide mechanism that guides the second panel to the unfolded position when the first panel rotates to the upright position and guides the second panel to the folded position when the first panel rotates to the inclined position.

[0009] In this storage device, when the first panel is rotated from the reclined position to the upright position, the second panel biased by the biasing member is guided by the guide mechanism to rotate to the unfolded position, and when the first panel is rotated from the upright position to the reclined position, the second panel is guided by the guide mechanism to rotate to the folded position against the biasing force of the biasing member.

[0010] According to the above-mentioned storage device, the second panel rotates in conjunction with the rotational movement of the first panel. Therefore, compared to a configuration in which the rotational movement of the first panel and the rotational movement of the second panel are independent, the first panel and the second panel can be expanded with a simple operation, making it easier to use.

[0011] A second aspect of the present disclosure is a storage device described in the first aspect, wherein the guide mechanism comprises a guide portion provided in the storage portion and a guided portion provided on the second panel, the guide portion being an inclined surface that inclines toward the center of the rotation axis of the first panel as it moves in a direction away from the rotation axis in a plan view, and the guided portion slides along the inclined surface when the first panel is rotated.

[0012] In this storage device, the guide portion is an inclined surface that slopes toward the center of the rotation axis of the first panel, so that when the first panel rotates to the tilted position, the second panel is guided by the inclined surface and rotates to the folded position.

[0013] Therefore, according to this storage device, when the first panel is rotated to the tilted position, the second panel can be rotated smoothly.

[0014] A third aspect of the present disclosure is a storage device as described in the second aspect, wherein the storage section has a side wall rising from an end of the first panel in the rotation axis direction, the first panel is attached to the side wall, and the guide section is provided on the side wall.

[0015] In this storage device, since the storage section has a side wall, when the first panel is in an upright state, the second panel comes into contact with the side wall, thereby restricting rotation of the second panel. Also, since the storage section has a side wall, the first panel can be attached to the side wall, and a guide portion can be provided on the side wall.

[0016] Therefore, according to this storage device, it is possible to reduce the number of parts of the storage device.

[0017] A fourth aspect of the present disclosure is a storage device described in any one of the first to third aspects, wherein the first panel is rotatably connected to the storage section by a hinge mechanism, and the hinge mechanism includes a shaft provided on the first panel, a first cam arranged on an outer periphery of the shaft and movable along the shaft, a second cam removably attached to the storage section and engaging with the first cam to hold the first panel in the upright position and the reclined position, and a cam biasing member biasing the first cam toward the second cam.

[0018] In this storage device, the hinge mechanism has a first cam and a second cam, and the first cam is urged toward the second cam by a cam urging member, and the first cam and the second cam engage with each other when the first panel is in the upright position and the tilted position, thereby maintaining the position of the first panel.

[0019] Therefore, with this storage device, the first panel can maintain an upright position and a tilted position, and the user can tactilely know that the first panel has rotated to the upright position when rotating the first panel to the upright position, and that the first panel has rotated to the tilted position when rotating the first panel to the tilted position.

[0020] A fifth aspect of the present disclosure is a storage device described in any one of the first to fourth aspects, wherein the second panel is attached to both sides of the first panel, and the width of the second panel is less than half the width of the first panel.

[0021] According to this storage device, since the width of the second panel is equal to or less than half the width of the first panel, it is possible to prevent the second panels from interfering with each other when they rotate.

[0022] In a sixth aspect of the present disclosure, in the storage device according to any one of the first to fifth aspects, a rotation axis direction of the second panel is perpendicular to a rotation axis direction of the first panel.

[0023] With this storage device, the rotational axis direction of the second panel is perpendicular to the rotational axis direction of the first panel, making it easier to hold items between the first and second panels compared to, for example, a configuration in which the rotational axis direction of the second panel intersects with the rotational axis direction of the first panel.

[0024] A seventh aspect of the present disclosure is a storage device described in any one of the fourth to sixth aspects which reference the third aspect, wherein a cushioning material is attached to the second panel, and when the second panel is in the deployed position, the second panel abuts against the side wall via the cushioning material.

[0025] According to this storage device, when the second panel is unfolded, the second panel abuts against the side wall via the cushioning material, thereby reducing damage to the second panel or side wall compared to a configuration in which the second panel and the side wall abut directly.

[0026] An eighth aspect of the present disclosure is a storage device described in any one of the first to seventh aspects, wherein an inclined portion is provided at an end of the first panel opposite the side where the first panel is attached to the storage section, the inclined portion being inclined in the direction in which the first panel tilts.

[0027] In this storage device, when the first panel is in an upright state and a vertical force is applied to the first panel from above by a falling object or the like, a part of the vertical force applied is converted by the inclined portion of the first panel into a force that rotates the first panel in a tilting direction. In other words, the force applied vertically to the first panel is dispersed by the inclined portion.

[0028] Therefore, with this storage device, when a vertical force is applied to the first panel from above by a falling object or the like, the vertical force is dispersed by the inclined portion of the first panel, thereby preventing damage to the first panel.

[0029] A ninth aspect of the present disclosure is the storage device according to any one of the first to eighth aspects, wherein the storage section is configured to be movable in a direction to be pulled out from under the seat.

[0030] With this storage device, by pulling out the storage section from under the seat and then expanding the first and second panels, it is possible to place large items or multiple small items in the storage section. Effect of the Invention

[0031] According to the present disclosure, a user-friendly storage device can be provided. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] Hereinafter, a storage device according to an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, the same or equivalent components and parts are given the same reference numerals. In addition, the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.

[0034] The arrow UP in each drawing is vertical and points upward in the storage device 10. The arrow LH is horizontal and points leftward with respect to the rotation axis of the first panel 40 of the storage device 10. The arrow RH is horizontal and points rightward with respect to the rotation axis of the first panel 40 of the storage device 10. The arrow FR is horizontal and points forward in the storage device 10 (the direction in which the storage section 20 is pulled out). The arrow RR is horizontal and points backward in the storage device 10.

[0035] In the following description, the "up-down direction" may mean "both upward and downward directions" or "either upward or downward directions". The "left-right direction" may mean "both rightward and leftward directions" or "either rightward or leftward directions". The "left-right direction" may also be referred to as the lateral direction or horizontal direction. The "front-rear direction" may also be referred to as the forward direction or rearward direction or "either forward or rearward directions". The "front-rear direction" may also be referred to as the lateral direction or horizontal direction. The up-down direction, left-right direction, and front-rear direction are directions that are perpendicular to each other.

[0036] In addition, in the following description, "standing direction S1" refers to the direction in which the first panel 40 rotates from a tilted position in which it is tilted relative to the storage section 20 to an upright position in which it is upright relative to the storage section 20, and "tilting direction S2" refers to the direction in which the first panel 40 rotates from an upright position in which it is upright to a tilted position in which it is tilted.

[0037] In addition, in the following description, "unfolding direction D1" refers to the direction in which the second panel 50 rotates from a folded position in which it is folded relative to the first panel 40 to an unfolded position in which it is opened outward in the left and right directions, and "folding direction" refers to the direction in which the second panel 50 rotates from an unfolded position in which it is unfolded to a folded position in which it is folded relative to the first panel 40.

[0038] (composition) 1 is a perspective view showing a state in which a storage device 10 of this embodiment is pulled out from a storage section 98 under a vehicle seat 90 and used. The storage device 10 of this embodiment includes, as an example, a storage section 20, a first panel 40, and a second panel 50.

[0039] 1, the storage section 20 is a portion of the storage device 10 where luggage (not shown) can be placed. The storage section 20 has a bottom plate 24 extending in the front-rear direction of the storage device 10 and side walls 22 rising vertically from both ends of the bottom plate 24 in the left-right direction.

[0040] 1, a pull portion 36 is provided in front of the storage unit 20. The pull portion 36 is a portion that is pulled when a user pulls out the storage device 10 stored under the seat 90 in the storage unit 20.

[0041] Further, the pulling portion 36 has a portion that rises in front of the storage portion 20 with respect to the bottom plate 24. That is, the pulling portion 36 also serves as a front wall of the storage portion 20.

[0042] The first panel 40 is attached to the front of the storage section 20 so as to be rotatable (rotatable) about an axis in the horizontal direction perpendicular to the pull-out direction, i.e., the left-right direction of the storage section 20, and can take an attitude in an upright position as shown in Fig. 1 and an attitude in a tilted position tilted backward, which will be described later. Here, the attitude of the first panel 40 in the upright position refers to the upright state of the first panel 40, and the attitude of the first panel 40 in the tilted position refers to the tilted state of the first panel 40.

[0043] The second panel 50 is provided on both left and right ends of the first panel 40 so as to be rotatable about a vertical axis perpendicular to the front-rear direction, and can assume an unfolded position as shown in Fig. 1 and a folded position as described below when the first panel 40 is in an upright state. Here, the posture of the second panel 50 in the unfolded position refers to the unfolded state of the second panel 50, and the posture of the second panel 50 in the folded position refers to the folded state of the second panel 50.

[0044] As shown in FIG. 1, the storage device 10 of this embodiment is used in such a state that, as an example, when in use, the storage section 20 is pulled out by the user from the storage section 98 under the vehicle seat 90, and the first panel 40 attached to the storage section 20 is raised and the second panel 50 is unfolded.

[0045] The front-rear direction, left-right direction, and up-down direction of the seat 90 coincide with the front-rear direction, left-right direction, and up-down direction of the storage device 10.

[0046] As shown in FIG. 1, when the first panel 40 is erected and the second panel 50 is unfolded, the vertical height of the first panel 40 and the second panel 50 is greater than the side wall 22 of the storage section 20.

[0047] In other words, by having the first panel 40 stand up and the second panel 50 unfolded, the storage device 10 becomes capable of placing large items or multiple small items in the storage section 20.

[0048] In addition, the first panel 40 and the second panel 50 of the storage device 10 of this embodiment can be configured to be in the state shown in FIG. 1 such that the second panel 50 is folded and the first panel 40 is tilted toward the storage section 20.

[0049] When the second panel 50 is folded and the first panel 40 is tilted into the storage section 20, the first panel 40 and the second panel 50 are stored in the storage section 20 having the side walls 22 and the bottom plate 24, so that the storage device 10 can be stored in the storage section 98 under the seat 90.

[0050] The manner in which the user stands up the first panel 40 and unfolds the second panel 50, and the manner in which the user tilts the first panel 40 and folds the second panel 50 will be described later.

[0051] Next, the storage device 10 of this embodiment will be described with reference to FIG. 2 to FIG.

[0052] FIG. 2 is a perspective view showing the storage device 10 of this embodiment as viewed from the rear.

[0053] As shown in FIG. 2, a rail fitting portion 32 is formed on the upper portion of the side wall 22 along the front-rear direction, protruding outward in the left-right direction from the outer surface of the side wall 22 in the left-right direction beyond the side wall 22.

[0054] Moreover, the rail fitting portion 32 is shaped to fit loosely with a rail 92 (see also FIG. 5) formed in a storage portion 98 under the seat 90.

[0055] At the rear end of the storage section 20, a rear wall 38 is formed that rises vertically from the bottom plate 24. That is, the storage section 20 is shaped like a box that is open at the top, and is made up of the bottom plate 24, the side walls 22 formed on both the left and right sides of the bottom plate 24, the rear wall 38, and the tensioning section 36.

[0056] Incidentally, the storage section 20 of the present embodiment is formed of a hard resin, for example.

[0057] In addition, in the storage section 20 of this embodiment, as an example, the bottom plate 24, the tension portion 36, the rear wall 38, and the side wall 22 are each formed integrally, but this is not limited thereto, and they may be formed as separate bodies and combined to form the storage section 20.

[0058] As shown in FIGS. 3 and 4, extensions 96 are formed on both left and right sides of the rear wall 38.

[0059] (Extending part 96) As an example, the extension portion 96 is a portion that extends from the rear wall 38 of the storage section 20 rearward beyond the rail fitting portion 32 and outward in the left-right direction.

[0060] 3 and 4, the extension portion 96 is formed to have a vertical length longer than the rail fitting portion 32. In other words, when the storage device 10 is viewed from the rear side, the extension portion 96 is formed to protrude at least on one side, either above or below, the rail fitting portion 32.

[0061] As shown in FIGS. 3 and 4, the extension portion 96 is formed to extend from the rear surface of the rear wall 38 slightly inward in the left-right direction beyond the rail fitting portion 32.

[0062] As shown in Figs. 3 and 4, it is preferable that a recess 33 recessed inward in the left-right direction be provided on the outer side and front side of the extension portion 96 in the left-right direction.

[0063] FIG. 5 is a rear view showing how the storage device 10 of this embodiment is loosely fitted into the groove of a rail 92 provided in a storage section 98 under a seat 90. As shown in FIG.

[0064] As shown in FIG. 5, the storage section 98 is provided with rails 92 on both left and right sides, each rail 92 being substantially U-shaped and having a groove portion that opens inward in the left and right direction.

[0065] The rails 92 extend in the front-rear direction of the storage device 10, i.e., in the front-rear direction of the storage section 98, longer than the length of the storage device 10 that is pulled out.

[0066] Here, the groove portion of the rail 92 and the rail fitting portion 32 are formed so as to create a slight gap when they are combined.

[0067] That is, since the groove of the rail 92 and the rail fitting portion 32 fit loosely into each other, the storage device 10 can be pulled out and stored in the front-rear direction while being supported by the groove of the rail 92 by the rail fitting portion 32.

[0068] 1, when the storage device 10 is pulled out, the length of the groove of the rail 92 loosely fitted into the rail fitting portion 32 is shorter than when the storage device 10 is stored. This raises concerns about the storage device 10 tilting to the left or right.

[0069] (Actions and Effects of Extension Portion 96) In the storage device 10 of this embodiment, as shown in FIG. 5, with the rail fitting portion 32 loosely fitted in the groove portion, the extension portion 96 faces the rail 92 with a small gap therebetween.

[0070] Therefore, even if the storage device 10 tilts left or right, the extensions 96 come into contact with parts of the rails 92 other than the grooves, reducing left or right tilt of the storage device 10, i.e., wobbling.

[0071] In the above description, the extension 96 is formed integrally with the rear wall 38, but it may be formed separately from the rear wall 38 and attached thereto.

[0072] In addition, although the extension portion 96 in this embodiment is formed only on both the left and right sides of the rear wall 38, this is not limited to this as long as it extends rearward beyond the rail fitting portion 32 and is shaped to face the rail 92 with a small gap between them.

[0073] Next, the first panel 40 and the second panel 50 of the present embodiment will be described.

[0074] (First panel 40 and second panel 50) FIG. 6 is a diagram illustrating a state in which the first panel 40 of this embodiment is erected and the second panel 50 is unfolded.

[0075] As shown in FIG. 6, the first panel 40 of this embodiment is a plate material that has an inclined portion 42 at the upper part when upright and hinge mounting portions 44 on both the left and right sides of the lower part, and as an example, is generally rectangular when viewed from the front.

[0076] Also, as shown in FIG. 1, the vertical length of the first panel 40 in an upright state is longer than the side wall 22 and the pulling portion 36 of the storage section 20, and as an example, protrudes 100 mm above the storage section 20.

[0077] The length of the first panel 40 in the left-right direction is set to a length that allows it to be stored between the side walls 22 of the storage section 20.

[0078] The hinge attachment portions 44 are recessed portions on both left and right sides of the lower portion of the first panel 40, and are adapted to attach a hinge mechanism 60 (see also FIG. 8).

[0079] In addition, the first panel 40 is connected to the side wall 22 of the storage section 20 via a hinge mechanism 60 attached to the hinge mounting portion 44. The hinge mechanism 60 will be described later.

[0080] The first panel 40 is formed of, for example, a hard resin.

[0081] As shown in FIG. 6, the second panel 50 is a pair of plate members provided on both left and right sides of the first panel 40 via an unfolding mechanism 80.

[0082] The second panel 50 is formed of, for example, a hard resin. The storage section 20, the first panel 40, and the second panel 50 constituting the storage device 10 may be made of the same resin, or may be made of different resins.

[0083] The width of the second panel 50, that is, the length in the front-rear direction shown in FIG. 6, is set to be half or less of the width (length in the left-right direction) of the first panel 40.

[0084] 6, the second panel 50 is a member that is symmetrical in the left-right direction to the first panel 40. In the following description, when there is no need to distinguish between the pair of left and right second panels 50, they will be referred to as the second panels 50, and when there is a particular need to distinguish between them, they will be referred to as the right second panel 50A and the left second panel 50B.

[0085] 6, the second panel 50 is biased in the deployment direction D1 relative to the first panel 40 by a panel biasing member 82 of the deployment mechanism 80. Note that the panel biasing member 82 may be any member, and one example is a torsion spring.

[0086] Also, as shown in FIG. 6, the lower part of the second panel 50 is formed, for example, with an extension portion 52 that expands downward on the rear side in the fore-and-aft direction, and a guided portion 56 that protrudes downward on the front-to-back side of the extension portion 52.

[0087] 6 and 7 described later, a cushioning material 54 is attached to a lower edge portion 52U of the extension portion 52 so as to sandwich the lower edge portion 52U. The cushioning material 54 may be any soft material, but in this embodiment, felt is used as an example.

[0088] In addition, the position and length at which the cushion material 54 is attached are not particularly limited as long as they are the position and length at which the extension portion 52 abuts the side wall 22 as described below, but as an example, the length is about half the length from the lower end of the extension portion 52 to the lower side of the lower edge portion 52U when the second panel 50 is unfolded. In addition, the cushion material 54 is not shown in the figures other than Figures 6 and 7.

[0089] 7A and 7B are diagrams illustrating the right side second panel 50A, where FIG. 7A is a front view of the right side second panel 50A, and FIG. 7B is a cross-sectional view of the right side second panel 50A as viewed from the 7A-7A direction.

[0090] As shown in FIG. 7B, the guided portion 56 has, for example, a sliding surface 58 on the outer side in the left-right direction.

[0091] The sliding surface 58 is a portion that bulges outward in the left-right direction from the inner side of the right second panel 50A and inclines inward in the left-right direction toward the rear side of the right second panel 50A.

[0092] In addition, when attached to the first panel 40, the left second panel 50B is plane-symmetrical to the right second panel 50A.

[0093] Next, the hinge mechanism 60 of the storage device 10 of this embodiment will be described with reference to Figs. 8 to 10 as appropriate.

[0094] (hinge mechanism 60) FIG. 8 is a diagram illustrating the hinge structure by cutting away a portion of the right side of the first panel 40 of this embodiment.

[0095] As shown in FIG. 8, the hinge mechanism 60 comprises a shaft 64 provided on the first panel 40, a first cam 66 arranged on the outer periphery of the shaft 64 and movable along the shaft 64, a second cam 74 that is removably attached to the storage section 20 and engages with the first cam 66 to hold the first panel 40 in the upright position and the reclined position, and a cam biasing member 62 that biases the first cam 66 toward the second cam 74.

[0096] The shaft 64 is attached to the lower part of the first panel 40 when the first panel 40 is in an upright state, and is a rotation axis of the first panel 40 , and is provided in the left-right direction with respect to the first panel 40 .

[0097] As shown in Figure 9, the first cam 66 has a bearing portion 72 on the approximately cylindrical side into which the shaft 64 is inserted, a claw portion 70 extending radially from the bearing portion 72 on the outer peripheral surface of the bearing portion 72, and a first engagement portion 68 formed at an end portion on one axial side relative to the bearing portion 72 and having a peak portion 68M and a valley portion 68V aligned circumferentially when viewed from the one axial side.

[0098] The claw portion 70 is hooked onto the hinge attachment portion 44 of the first panel 40 to limit the relative movement between the first cam 66 and the second cam 74 .

[0099] The peak portions 68M of the first engagement portion 68 are portions that protrude from the end of the first engagement portion 68 with an apex on one axial side, and as shown in Figure 9(B), four of them are formed in a line at equal intervals around the circumference of the first engagement portion 68.

[0100] In addition, having a peak refers to a shape in which, when the peak portion 68M of the first engagement portion 68 is viewed circumferentially, one point protrudes the most, and on both sides of that point, the amount of protrusion to one side in the axial direction decreases as they move away from each other in the circumferential direction.

[0101] The valley portion 68V of the first engagement portion 68 is a portion formed between the peak portion 68M of the first engagement portion 68 and other peak portions 68M arranged circumferentially, and is recessed symmetrically toward the other axial side with respect to the protruding shape of the peak portions 68M.

[0102] As shown in FIG. 10, the second cam 74 has a second engagement portion 76 and a mounting portion 78 formed on the surface opposite to the second engagement portion 76 .

[0103] The second engagement portion 76 is a portion that engages with the first engagement portion 68 of the first cam 66, and has a peak portion 76M that protrudes from the second cam 74 and engages with a valley portion 68V of the first engagement portion 68, and a valley portion 76V that is formed between the peak portion 76M of the second engagement portion 76 and the other peak portion 76M and engages with the peak portion 68M of the first engagement portion 68.

[0104] The mounting portion 78 is attachable to the side wall 22 of the storage portion at a portion opposite the second engagement portion 76 .

[0105] The mounting portion 78 may be attached to the side wall 22 in any manner. In this embodiment, as shown in FIG. 16, the mounting portion 78 is accommodated and fixed in a side wall accommodation portion formed on the inner front surface of the side wall 22. The side wall accommodation portion is composed of the pulling portion 36 and a protrusion 22P that is disposed rearwardly from the pulling portion 36 and protrudes from the side wall 22 and extends in the up-down direction. The mounting portion 78 is maintained accommodated in the side wall accommodation portion by receiving the biasing force of the cam biasing member 62. The mounting portion 78 is restricted in its movement in the front-rear direction and its rotation by contacting the pulling portion 36 with the protrusion 22P. The mounting portion 78 has a mounting portion inclined surface 78S (see FIG. 6 and FIG. 10B) that inclines inward in the left-right direction as it moves from the front to the rear at a portion facing the protrusion 22P.

[0106] The first cam 66 and the second cam 74 may be made of any material as long as the material has sufficient rigidity to prevent the material from being easily deformed.

[0107] As shown in FIG. 8, the cam biasing member 62 is, for example, a compression spring, one end of which is fixed to the first panel 40, and the other end of which biases the first cam 66 in one axial direction.

[0108] 8, the hinge mechanism 60 is explained with a portion of the right side of the first panel 40 cut away, but the left side of the first panel 40 is symmetrical to the right side of the first panel 40. That is, the shaft 64, the cam biasing member 62, the first cam 66, and the second cam 74 are each provided in pairs on the left and right.

[0109] (Rotation of the first panel 40 in the standing direction S1) Next, how the first panel 40 of this embodiment rotates from the reclined position to the standing position and how the second panel 50 changes from the folded state to the unfolded state will be described with reference to FIGS. 11 and 12 as appropriate.

[0110] FIG. 11 is a diagram illustrating how the first panel 40 of this embodiment rotates from the reclined position to the upright position, and the second panel 50 changes from the folded state to the unfolded state.

[0111] FIG. 12 is a diagram showing the operation of one hinge mechanism 60 when the first panel 40 of this embodiment rotates from the reclined position to the upright position, with the first panel 40 omitted.

[0112] In addition, although FIG. 12 shows only the right-side hinge mechanism 60 among the hinge mechanisms 60 of this embodiment, the left-side hinge mechanism 60 operates in the same manner.

[0113] First, as shown in FIG. 11(A), when the first panel 40 is in the tilted state, the second panel 50 is folded between the first panel 40 and the bottom plate 24.

[0114] Also, as shown in FIG. 12(A), the first cam 66 is biased outward in the left-right direction by the cam biasing member 62, so that the peak 68M of the first engagement portion 68 and the valley 76V of the second engagement portion 76, and the valley 68V of the first engagement portion 68 and the peak 76M of the second engagement portion 76, respectively, remain engaged with each other.

[0115] In this state, the user rotates the first panel 40 into the standing direction S1.

[0116] As shown in FIG. 11(B), while the first panel 40 is rotating from the reclined state to the upright state, the second panel 50 transitions from the folded state to the unfolded state in conjunction with the rotation of the first panel 40 because the panel biasing member 82 biases the second panel 50 in the unfolding direction D1.

[0117] Furthermore, as shown in FIG. 12(B), the first cam 66 rotates in conjunction with the rotation of the first panel 40, so that the top of the peak 68M of the first engagement portion 68 and the depression of the valley 76V of the second engagement portion 76, and the depression of the valley 68V of the first engagement portion 68 and the top of the peak 76M of the second engagement portion 76 are misaligned in the circumferential direction.

[0118] In addition, in this state, the ridge portion 68M of the first engagement portion 68 moves toward the apex of the ridge portion 76M of the second engagement portion 76, so that the first cam 66 moves while being biased by the cam biasing member 62 toward the other axial side.

[0119] Here, if the peak 68M of the first engagement portion 68 does not exceed the apex of the peak 76M of the second engagement portion 76, the peak 68M of the first engagement portion 68 is urged by the urging force of the cam urging member 62 in a direction returning to a position where it engages with the valley portion 76V of the second engagement portion 76.

[0120] In other words, when the peak 68M of the first engagement portion 68 has not exceeded the apex of the peak 76M of the second engagement portion 76, the first cam 66 is biased in the tilt direction S2 in accordance with the shape of the peak 76M of the second engagement portion 76 on the tilt direction S2 side, and therefore the first panel 40 is biased in the tilt direction S2.

[0121] On the other hand, as shown in FIG. 12(B), when the first panel 40 is rotated approximately 45°, the top of the ridge 68M of the first engagement portion 68 is in a position to abut against the top of the ridge 76M of the second engagement portion 76.

[0122] Then, when the top of the peak 68M of the first engagement portion 68 exceeds the top of the peak 76M of the second engagement portion 76 in the standing direction S1 of the first panel 40, the peak 68M of the first engagement portion 68 is urged in a direction toward engaging with the adjacent valley portion 76V in the standing direction S1 relative to the valley portion 76V with which it was engaged when the first panel 40 was tilted.

[0123] In other words, when the top of the peak 68M of the first engagement portion 68 exceeds the top of the peak 76M of the second engagement portion 76, the first cam 66 is urged in the standing direction S1 in accordance with the shape of the standing direction S1 side of the peak 76M of the second engagement portion 76, and the first panel 40 is urged in the standing direction S1.

[0124] Then, as shown in FIG. 11(C), when the first panel 40 has been rotated to the upright position, the second panel 50 is rotated by the panel biasing member 82 until the lower edge 52U of the extension portion 52 abuts against the side wall 22 via the cushion material 54.

[0125] That is, when the first panel 40 is in the upright position, the second panel 50 rotates to the deployed position.

[0126] Also, as shown in FIG. 12(C), the peak portion 68M of the first engagement portion 68 engages with the valley portion 76V adjacent in the standing direction S1 to the valley portion 76V that engaged with the first cam 66 when the first panel 40 was tilted.

[0127] In this way, the first cam 66 is biased outward in the left-right direction by the cam biasing member 62, so that the first panel 40 remains in an upright state.

[0128] In this manner, by rotating the first panel 40 from a reclined state to an upright state, the second panel 50 transitions from a folded state to an unfolded state and maintains that state, while the first panel 40 remains in the upright state.

[0129] (Rotation of the first panel 40 in the tilt direction S2) As shown in FIGS. 11, 13 to 15, the storage device 10 of this embodiment has a guide portion 28 on the inside in the left-right direction and at a position where it comes into contact with the sliding surface 58 of the second panel 50.

[0130] The guided portion 56 of the second panel 50 and the guide portion 28 provided on the side wall 22 are an example of the "guide mechanism" of the storage device 10 of this embodiment.

[0131] FIG. 13 is a cutaway view of the second panel 50 and the guide portion 28 of this embodiment.

[0132] As shown in FIG. 13, guide portion 28 is an inclined surface 30 that inclines toward the center in the left-right direction, i.e., toward the center of the rotation axis of first panel 40, as it moves from the front to the rear of side wall 22 in a plan view, i.e., away from the rotation axis of first panel 40, and is provided on the rear side of the guided surface of second panel 50 when first panel 40 is upright and second panel 50 is unfolded.

[0133] Therefore, the guide portion 28 comes into sliding contact with the sliding contact surface 58 of the second panel 50 when the first panel 40 is between the angle when it is in the unfolded state and the angle when it is in the tilted state.

[0134] It is preferable that the guide portion 28 is further inclined toward the center in the left-right direction as it goes from the top to the bottom of the side wall 22.

[0135] FIG. 14 is a diagram showing the state in which the first panel 40 of this embodiment is erected and the second panel 50 is unfolded.

[0136] As shown in FIG. 14, the guide portion 28 is located rearward and below the guided portion 56 when the second panel 50 is in an unfolded state.

[0137] Furthermore, in a state in which the first panel 40 is slightly rotated in the tilt direction S2, the sliding contact surface 58 of the second panel 50 comes into sliding contact with the inclined surface 30 of the guide portion .

[0138] 15, when the sliding surface 58 of the second panel 50 is in sliding contact with the inclined surface 30 of the guide portion 28, the second panel 50 rotates following the inclined surface 30 of the guide portion 28.

[0139] That is, the sliding contact surface 58 comes into sliding contact with the inclined surface 30 of the guide portion 28, causing the second panel 50 to rotate in the folding direction D2.

[0140] Furthermore, by further rotating the first panel 40 in the tilt direction S2, the lower edge 52U of the second panel 50 comes into contact with the bottom plate 24, so that the second panel 50 further rotates in the folding direction.

[0141] Then, by rotating the second panel 50 in the folding direction and rotating the first panel 40 in the tilting direction S2, the second panel 50 is folded so as to be sandwiched between the first panel 40 and the bottom plate 24, and the first panel 40 is in a tilted state as shown in Figure 11 (A).

[0142] (effect) The effects of the storage device 10 of this embodiment will be described below.

[0143] In the storage device 10 of this embodiment, when the first panel 40 is rotated from the tilted position to the upright position, the second panel 50 biased by the biasing member is guided by the guide mechanism (the guided portion 26 and the guide portion 28) and rotates to the unfolded position. Also, when the first panel 40 is rotated from the upright position to the tilted position, the second panel 50 is guided by the guide mechanism and rotates to the folded position against the biasing force of the biasing member.

[0144] Therefore, according to the storage device 10 of this embodiment, the second panel 50 rotates in conjunction with the rotational movement of the first panel 40. Therefore, compared to a configuration in which the rotational movement of the first panel 40 and the rotational movement of the second panel 50 are independent, the first panel 40 and the second panel 50 can be expanded with a simple operation, making it easier to use.

[0145] Furthermore, in the storage device 10 of this embodiment, the guide portion 28 is an inclined surface 30 that inclines toward the center of the rotation axis of the first panel (in other words, toward the inside in the left-right direction), so that when the first panel 40 rotates to the tilted position, the second panel 50 is guided by the inclined surface 30 and rotates to the folded position.

[0146] Therefore, according to the storage device 10 of this embodiment, when the first panel 40 is rotated to the inclined position, the second panel 50 can be rotated smoothly.

[0147] In the storage device 10 of this embodiment, since the storage section 20 has the side wall 22, the rotation of the second panel 50 is restricted when the first panel 40 is in an upright position. Since the storage section 20 has the side wall 22, the first panel 40 can be connected to the side wall 22, and the guide section 28 can be provided on the side wall 22.

[0148] Therefore, according to the storage device 10 of this embodiment, it is possible to reduce the number of parts of the storage device 10.

[0149] Furthermore, in the storage device 10 of this embodiment, the hinge mechanism 60 has a first cam 66 and a second cam 74, and when the first panel 40 is at an angle between the angle of the upright position and the angle of the tilted position, the tops formed on the first cam 66 and the second cam 74 abut against each other. Therefore, when the first panel 40 is at an angle between the upright and tilted positions, the first cam 66 is biased outward in the left-right direction, thereby maintaining the upright and tilted positions of the first panel 40.

[0150] Therefore, according to the storage device 10 of this embodiment, the first panel 40 can maintain an upright position and a tilted position. When the first panel 40 is rotated to the upright position, the user can tactilely know that the first panel 40 has rotated to the upright position, and when the first panel 40 is rotated to the tilted position, the user can tactilely know that the first panel 40 has rotated to the tilted position.

[0151] In the storage device 10 of this embodiment, the second panel 50 is attached to both side portions of the first panel 40, and the width of the second panel 50 is half the width of the first panel 40 or less.

[0152] Therefore, according to the storage device 10 of this embodiment, since the width of the second panel 50 is less than half the width of the first panel 40, it is possible to prevent each second panel 50 from interfering with each other when they rotate and move.

[0153] In the storage device 10 of this embodiment, the rotation axis direction of the second panel 50 is perpendicular to the rotation axis direction of the first panel 40 .

[0154] Therefore, according to the storage device 10 of this embodiment, the rotational axis direction of the second panel 50 is perpendicular to the rotational axis direction of the first panel 40, making it easier to hold items between the first panel 40 and the second panel 50 compared to, for example, a configuration in which the rotational axis direction of the second panel 50 intersects with the rotational axis direction of the first panel 40.

[0155] In the storage device 10 of this embodiment, a cushion material 54 that comes into contact with the side wall 22 is attached to the lower edge 52U of the extension portion 52 of the second panel 50 when the second panel 50 is in the deployed position.

[0156] Therefore, according to the storage device 10 of this embodiment, the second panel 50 abuts against the side wall 22 at the lower edge 52U via the cushioning material 54, thereby preventing damage to the second panel 50 and the side wall 22 compared to when the second panel 50 directly abuts against the side wall 22.

[0157] In addition, in the storage device 10 of this embodiment, an inclined portion 42 that inclines in the direction in which the first panel 40 tilts is provided at the end of the first panel 40 opposite the side where it is attached to the storage section 20.

[0158] For this reason, in the storage device 10 of this embodiment, when the first panel 40 is in an upright state and a vertical force is applied to the first panel 40 from above by a falling object or the like, a part of the vertically applied force is converted by the inclined portion 42 of the first panel 40 into a force that rotates the first panel 40 in a tilting direction. In other words, the force applied vertically to the first panel 40 is dispersed by the inclined portion 42.

[0159] Therefore, according to the storage device 10 of this embodiment, when a vertical force is applied to the first panel 40 from above by a falling object or the like, the vertically applied force is dispersed by the inclined portion 42 of the first panel 40, thereby preventing damage to the first panel 40.

[0160] In addition, in the storage device 10 of this embodiment, the mounting portion 78 is provided with a mounting portion inclined surface 78S, and the side wall 22 is provided with a protrusion 22P facing the mounting portion inclined surface 78S. Here, when the first panel 40 is in a standing state and a force is applied to further rotate the first panel 40 in the standing direction S1, the mounting portion inclined surface 78S guides the second cam 74 inward in the left-right direction, and the cam biasing member 62 is compressed. Then, when the cam biasing member 62 is compressed by a predetermined amount, the mounting portion 78 (mounting portion inclined surface 78S) overcomes the protrusion 22P. Therefore, in the storage device 10 of this embodiment, when the first panel 40 is in a standing state and a force is applied to further rotate the first panel 40 in the standing direction S1, the hinge mechanism 60 comes off the side wall 22, so that damage to the first panel 40 can be suppressed.

[0161] In the storage device 10 of this embodiment, the storage section 20 is configured to be movable in a direction to be pulled out from under the seat 90.

[0162] Therefore, according to the storage device 10 of this embodiment, by pulling out the storage section 20 from under the seat 90 and then expanding the first panel 40 and the second panel 50, it is possible to place large items or a large number of small items in the storage section 20.

[0163] As described above, the storage device 10 according to the present disclosure can improve user convenience and provide a comfortable environment, which is a universal issue.

[0164] (Modification) A modification of the storage device 10 of this embodiment will be described below.

[0165] In the above description, the guide mechanism is described as the guide portion 28 provided on the side wall 22 and the guided portion 56 formed on the second panel 50, but the guide mechanism is not limited to the configuration described above as long as it is a mechanism that rotates the second panel 50 in the unfolded state in the folding direction D2.

[0166] In addition, in the above description, the guide portion 28 has an inclined surface 30, but as long as it can rotate the second panel 50 in the rotational direction by sliding contact with the guided portion 56, it is not limited to an inclined surface 30 and may, for example, simply be a bulge.

[0167] In addition, in the above description, the storage section 20 has side panels, but it is also possible to stop the rotation of the second panel 50 by providing stoppers protruding vertically on both the left and right sides of the bottom plate 24 without having side panels.

[0168] In the above description, the first panel 40 is rotatable by the hinge mechanism 60, but the hinge mechanism 60 does not have to be structured to maintain the upright state. For example, the upright state of the first panel 40 may be maintained by using another mechanism for maintaining the position, such as a stopper.

[0169] In addition, in the above description, the second panel 50 has a symmetrical shape on the left and right sides, but the shapes of the left and right second panels 50 may be different, or only one of the left and right second panels 50 may be used.

[0170] Even in this case, by unfolding the second panel 50, the amount of luggage that can be stored in the storage section 20 can be increased.

[0171] In addition, in the above description, the left and right second panels 50 rotate simultaneously, but this is not limiting, and the timing at which the second panel 50 rotates may be made different by making the front-to-rear positions of the left and right guide portions 28 different for each of the left and right guide portions 28. In this case, by making the width of the left and right second panels 50 half or more of the width of the first panel 40, the left and right panels can be folded so as to overlap each other when the second panel 50 is in a folded state.

[0172] In this case, the length of the second panel 50 can be made longer than half the length of the first panel 40 in the left-right direction, so the length by which the storage device 10 can be pulled out from under the seat 90 can be made longer than half the length of the first panel 40, thereby increasing the amount of luggage that can be placed in the storage section 20.

[0173] In addition, in the above description, the cushioning material 54 is attached to the lower edge 52U of the second panel 50, but if the material strength of the second panel 50 and the side wall 22 is sufficiently high, the cushioning material 54 does not need to be provided.

[0174] In the above description, the first panel 40 has the inclined portion 42, but the first panel 40 may be a flat plate-like member that does not have the inclined portion 42.

[0175] In the above description, the first panel 40 is attached to the side wall 22 via a hinge mechanism 60, but this is not limited to this. The first panel 40 may be attached to bearings that protrude vertically on both sides of the front of the bottom plate 24.

[0176] In the above description, the mounting portion 78 of the second cam 74 is detachable from the side wall 22, but this is not limiting and the mounting portion 78 may be fixed.

[0177] In the above description, the storage device 10 of this embodiment is used by being pulled out from under the seat 90, but the present invention is not limited to this, and the storage device 10 may be used by lifting up the seat surface of the seat 90.

[0178] One embodiment of the present disclosure has been described above with reference to the attached drawings. However, it is clear that a person with ordinary knowledge in the technical field to which the present disclosure pertains can conceive of various modifications or applications within the scope of the technical ideas described in the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure.
