DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For convenience of explanation, the arrow UP shown in FIG. 1 indicates the upward direction of the vehicle, the arrow FR indicates the forward direction of the vehicle, and the arrow RH indicates the rightward direction of the vehicle. Therefore, in the following description, unless otherwise specified, when the directions of up / down, front / rear, and left / right are mentioned, they refer to the up / down, front / rear, left / right of the vehicle. Furthermore, the left / right direction is synonymous with the vehicle width direction.

[0011] 1 to 3, a wheelchair storage device for an automobile (hereinafter simply referred to as "wheelchair storage device") 10 according to this embodiment is designed to be detachably attached to the luggage compartment 16 of an automobile 12 in which the passenger compartment 14 and the luggage compartment 16 are integrated into one space. In other words, the wheelchair storage device 10 is designed to be attached to the rear side of the rear seat 18.

[0012] 1 and 2, the wheelchair storage device 10 comprises a main body 20 incorporating a motor (not shown) as a drive source, a rail section 30 detachably provided on the rear side of the main body 20, and a cart section 40 configured to be movable along the rail section 30. The weight of the wheelchair storage device 10 equipped with these components is approximately 6.6 kg, making it lightweight.

[0013] Furthermore, the power cable 24 for supplying electricity to the motor, etc. is configured to be connectable to an accessory socket (not shown) provided on the automobile 12. In other words, the wheelchair storage device 10 can be driven by power (12V) from the accessory socket. When the wheelchair storage device 10 is not in use, the power cable 24 is fixed to the vehicle body that forms the luggage compartment 16 by a hook-and-loop fastener (not shown) or the like.

[0014] The main body 20 has a rectangular box-shaped housing 22, and a fixing belt 23 (see FIG. 2) is integrally attached to the front of the housing 22. Therefore, the main body 20 (housing 22) is configured to be detachably attached by wrapping and fixing the fixing belt 23 around a seat back frame (not shown) of the rear seat 18 whose axial direction is the vehicle width direction. In other words, this allows the main body 20 to be detachably attached to the luggage compartment 16 of the automobile 12.

[0015] A motor is provided within the housing 22 of the main body 20 so as to be rotatable in both forward and reverse directions with the vehicle width direction as its axial direction, and an operation switch 26 (remote control) for operating the rotational drive of the motor is provided via a wiring cable 28. That is, the motor is configured to be rotated in the forward direction or the reverse direction by operating the operation switch 26. The wiring cable 28 is fixed to the vehicle body constituting the luggage compartment 16 by a hook-and-loop fastener (not shown) or the like, and the operation switch 26 can be stored in a holder (not shown) provided on the vehicle body.

[0016] A motor pulley (not shown) is provided on the rotating shaft of the motor. One end of a support belt (not shown) is attached to and wound around the motor pulley, and the support belt is wound around a pulley (not shown) provided in the center of the back surface of the cart section 40 (cart main body 42). The other end of the support belt is attached to a bracket (not shown) provided on the housing 22.

[0017] As a result, when the motor is driven to rotate in the forward direction, the support belt is wound around the motor pulley, and the trolley section 40 moves upward (towards the rear seat 18) along the rail section 30. When the motor is driven to rotate in the reverse direction, the weight of the trolley section 40 also acts, and the trolley section 40 moves downward (outside the vehicle) along the rail section 30.

[0018] The rail section 30 is composed of a pair of short, left and right front rails 32 fixed to the housing 22 of the main body section 20, and a pair of long, left and right rear rails 34 that are detachably fitted into the pair of left and right front rails 32. Note that the rail section 30 that is detachably attached to the main body section 20 mainly refers to the rear rails 34, since the front rails 32 are configured integrally with the main body section 20.

[0019] The front rail 32 extends linearly rearward from the main body 20. The rear rail 34, on the other hand, is composed of a curved section 34A that extends downward from the front rail 32 in an arc-like shape, and a straight section 34B that extends linearly downward integrally from the curved section 34A (see FIGS. 2 and 3). A height adjustment attachment 36 is provided at the lower end of the rear rail 34 (straight section 34B).

[0020] The height adjustment attachment 36 is configured so that its height position can be adjusted by a pair of adjustment screws 38 (see FIG. 1) provided on both the left and right sides of the attachment 36. This allows the lowest position of the truck section 40, which moves downward along the straight section 34B, to be adjusted for each vehicle type.

[0021] The bogie section 40 has a rectangular flat bogie body 42 whose longitudinal direction is the extension direction of the rail section 30, and fitting sections 41 provided on both the left and right sides of the back surface of the bogie body 42 are fitted into the rail section 30. A pulley whose axial direction is the normal direction of the bogie body 42 is provided in the center of the back surface of the bogie body 42, and as described above, the bogie section 40 is configured to be movable along the rail section 30 by winding and unwinding the support belt wound around the pulley.

[0022] Also, as shown in Figure 1, when the trolley section 40 is positioned on the straight section 34B, there are provided on both the left and right sides of the lower side of the surface of the trolley body 42 a roughly "J" shaped stopper arm 44 that presses against and holds the rear wheel 64 of the wheelchair 60, and an auxiliary arm 43 that supports the axle of the rear wheel 64, etc.

[0023] The stopper arm 44 and the auxiliary arm 43 have their lower ends rotatably supported near the corners on the lower side of the trolley body 42, and are configured to be able to take on a stored position in which they are positioned without protruding from the surface of the trolley body 42 when viewed from the normal direction of the trolley body 42, and an deployed position in which they rotate to the left and right, respectively, and protrude from the surface of the trolley body 42.

[0024] A cylindrical support rod 45 bent into a roughly "L" shape is provided on the top of the cart body 42. The height of this support rod 45 can be adjusted using an adjustment screw 48 (see FIG. 1). A hook 46 is provided at the tip (upper end) of the support rod 45 to secure the wheelchair 60 to the cart body 42 in a lifted state.

[0025] The hook 46 is made up of a flat plate bent into a roughly "L" shape, and a fixing band 47 can be attached to it. The hook 46 supports the frame 66 of the wheelchair 60 from below, and the fixing band 47 fixes the frame 66 to the hook 46.

[0026] 2, the front end of the rear rail 34 (curved portion 34A) constituting the rail section 30 is supported by the vehicle body constituting the luggage compartment 16 via a support member 50. A bogie fixing band 52 is detachably provided on the front end of the rear rail 34 (curved portion 34A) supported by the support member 50.

[0027] The rear end of the fixing belt 54 is removably connected to the tip of the trolley fixing band 52, and when the wheelchair 60 is not being stored, the fixing belt 54 fixes the rear rail 34, which has been removed from the front rail 32, to the top side of the trolley section 40 (the cover described later), which is held on the main body section 20 side, by winding the support belt around the motor pulley.

[0028] Specifically, a cover (not shown) is placed on the top surface of the bogie section 40 (bogie main body 42), and the rear rail 34 is placed on the top surface of the cover with its longitudinal direction (extension direction) facing the vehicle width direction. These are then fixed by attaching the forked front end of a fixing belt 54 to the seat back frame of the rear seat 18 at a distance in the vehicle width direction, and by attaching the rear end of the fixing belt 54 to the bogie fixing band 52.

[0029] In other words, the fixing belt 54 is laid across so as to form a substantial "Y" shape in a plan view. As a result, when the wheelchair 60 is not being stored, the rail section 30 (rear rail 34) and the cart section 40 are fixed to the luggage compartment 16 together with the main body section 20. Note that the fixing belt 54 is also used to secure the wheelchair 60 when it is stored.

[0030] Next, the operation of the wheelchair storage device 10 according to this embodiment configured as described above will be described.

[0031] As shown in Figure 1, the wheelchair 60 is folded. Then, the stopper arm 44 and auxiliary arm 43 attached to the cart body 42 are rotated so that they assume the unfolded position. After that, the front wheel 62 side of the wheelchair 60 is lifted and the wheelchair 60 is pushed in this state, so that the right rear wheel 64 of the wheelchair 60 is pressed against the stopper arm 44 and held in place.

[0032] Next, the frame 66 of the wheelchair 60 is hooked onto the hook 46 attached to the cart body 42 via the support rod 45. Then, the frame 66 is fixed to the hook 46 with the fixing band 47. Once the wheelchair 60 has been fixed to the cart body 42 in this way, the operation switch 26 is operated to drive the motor to rotate in the forward direction.

[0033] Then, the dolly section 40 (dolly body 42) holding the wheelchair 60 moves along the rail section 30 (from the rear rail 34 to the front rail 32), and as shown in Figure 3, the wheelchair 60 is stored in the luggage compartment 16. Once the wheelchair 60 has been stored in the luggage compartment 16, the rear rail 34 is removed from the front rail 32, and the rear rail 34 together with the wheelchair 60 are fixed by the fixing belt 54 connected to the dolly fixing band 52.

[0034] On the other hand, when removing the wheelchair 60 from the luggage compartment 16, the fixing belt 54 is released and the rear rail 34 is attached to the front rail 32. Then, the operation switch 26 is operated to drive the motor so that it rotates in the reverse direction. Then, the cart section 40 (cart main body 42) holding the wheelchair 60 moves along the rail section 30 (from the front rail 32 to the rear rail 34) and the cart section 40 (cart main body 42) stops at the lowest position.

[0035] When the cart section 40 (cart body 42) has stopped at the lowest position, the fixing band 47 is released, the frame 66 is removed from the hook 46, and the right rear wheel 64 is removed from the stopper arm 44. This causes the wheelchair 60 to detach from the cart section 40 (cart body 42).

[0036] Furthermore, the cart section 40 (cart main body 42) from which the wheelchair 60 has been removed is moved along the rail section 30 toward the main body section 20 by operating the operation switch 26. Then, the rear rail 34 is removed from the front rail 32, and as described above, the fixing belt 54 is hung across in a roughly "Y" shape in a plan view, and the rear rail 34 is fixed to the cart section 40 (cart main body 42).

[0037] After moving the dolly unit 40 (dolly body 42) toward the main body 20, unplug the power cable 24 from the accessory socket. When the wheelchair storage device 10 itself is not in use, remove the rear rail 34 from the front rail 32 and remove the fixing belt 23 of the main body 20 from the seat back frame of the rear seat 18. This allows the wheelchair storage device 10 itself to be removed from the luggage compartment 16.

[0038] As explained above, the rail portion 30 is detachably attached to the main body portion 20 in separate parts, and the main body portion 20 is detachably attached to the trunk 16 of the automobile 12. Therefore, as described above, the wheelchair storage device 10 can be removed from the trunk 16 by removing the rail portion 30 from the main body portion 20 and removing the main body portion 20 from the trunk 16.

[0039] In other words, the wheelchair storage device 10 can be easily attached and detached by the user as needed. Therefore, when the wheelchair storage device 10 is not in use, the luggage compartment 16 can be widely utilized (the usability of the luggage compartment 16 is not impaired). Furthermore, the wheelchair storage device 10 can store even a heavy electric wheelchair (not shown) using power obtained from the accessory socket without damaging the body of the wheelchair that makes up the luggage compartment 16.

[0040] Furthermore, as described above, this wheelchair storage device 10 can be retrofitted to an existing automobile 12 without modifying the interior of the luggage compartment 16, so it is possible to purchase only the wheelchair storage device 10. In other words, there is no need to buy a new automobile 12 in order to be able to store a wheelchair 60 in the luggage compartment 16.

[0041] Although the wheelchair storage device 10 for automobiles according to this embodiment has been described above with reference to the drawings, the wheelchair storage device 10 for automobiles according to this embodiment is not limited to the one shown in the drawings, and the design can be modified as appropriate within the scope of the gist of the present invention. For example, the shapes of the auxiliary arm 43 and the hook 46 are not limited to those shown in the drawings. [Explanation of symbols]
