Description

  TECHNICAL FIELD The present invention relates to a wheelchair storage device that can carry in and out a wheelchair and can assist a wheelchair user to transfer between a wheelchair seat and a vehicle seat as needed, and a vehicle equipped with the same. . In this specification, “transfer” means that a wheelchair user seated in a wheelchair changes to the vehicle seat, or vice versa, a person seated in the vehicle seat changes to the wheelchair seat.

  Conventionally, a foldable transfer board attached to a side surface of a seat is known. The wheelchair user deploys the transfer board while riding in the wheelchair. Then, the transfer board has the same height as the seat on the seat side, and is slightly lowered toward the outside in the vehicle width direction. Wheelchair users once transfer from the wheelchair to the transfer board and then transfer to the seat cushion. Thereafter, the wheelchair user folds the wheelchair and stores the wheelchair in the vehicle compartment. At that time, the wheelchair can be lifted from the ground using the transfer board as a slope. Thereafter, the wheelchair user sitting in the driver's seat can fold the transfer board and close the door.

  In addition, various devices for wheelchair users to ride in automobiles have been developed (for example, Patent Documents 1 to 3).

  For example, Patent Document 1 discloses a seat device that includes a seat main body and front and rear wheels and can be used alone as a wheelchair, and is installed in a vehicle interior, and the seat device is connected to the vehicle interior and the exterior of the vehicle interior. And a sheet moving device for moving between them. Therefore, it is possible to get on and off the vehicle while the seated person is seated on the seat body.

  The wheelchair disclosed in Patent Document 2 can be transferred between the seat body and the wheelchair using the vertical movement of the seat body by making the seating part of the wheelchair separable to the left or right or removable from the main frame. It is what.

  By the way, even if a wheelchair user moves from a wheelchair to a car, the wheelchair needs to be stored in the car. As an apparatus for a wheelchair user himself / herself to store a wheelchair in a vehicle compartment, for example, those disclosed in Patent Documents 4 to 7 are known.

  For example, it is considered that a wheelchair in-vehicle device is arranged on the floor surface between a first row seat and a second row seat in a passenger compartment, and the wheelchair is taken in and out in the vehicle width direction (Patent Documents 4 and 6).

  In the apparatus disclosed in Patent Document 4, a guide rail is provided on the floor surface with the end facing the automobile opening along the vehicle width direction at the rear part of the driver's seat, and the wheelchair mounted on the upper part is curved. An arm and a moving device that is reciprocated along the guide rail and attached to one end of the wheelchair placing arm are provided. This device can certainly store the wheelchair at the foot of the second row seat of the vehicle. However, if the wheelchair user is a driver, it takes much effort and labor. For example, after a wheelchair user has moved to the driver's seat, the user must fold the wheelchair by facing the outside of the vehicle, align the wheelchair so as to face the wheelchair mounted device, and place the wheelchair on the wheelchair mounted device. The same applies when the wheelchair is removed from the vehicle.

  Therefore, Patent Literature 5 discloses a wheelchair storage device in which the device disclosed in Patent Literature 4 is improved and a guide rail is arranged on the vehicle deck from the rear portion of the driver's seat toward the diagonally rear corner portion. Moreover, in the apparatus disclosed in Patent Document 6, it is necessary to provide a dedicated part on the wheelchair side. Thus, since special special parts are used, the wheelchair needs to be remodeled.

  As described above, in order to move the wheelchair in the vehicle interior, it is also considered that a guide member such as a rail is not disposed on the vehicle floor side but on the roof side in the vehicle interior. For example, the device disclosed in Patent Document 7 includes a rail disposed in an upper portion of a vehicle interior, and a lift device that guides and moves the rail and moves the wheelchair up and down. A connecting means that is attached to and detached from the head, a strip having a connecting means connected to the tip, a drum that winds up the strip, and a driving device that drives the drum. This reduces the weight of the wheelchair applied to the operator when raising the wheelchair from the outside of the vehicle, sleeping or waking up the wheelchair in the vehicle, moving it, or lowering it from the vehicle interior to the outside of the vehicle. In the device disclosed in Patent Document 6, after the rail crosses over the driver's seat from the vicinity of the door on the driver's seat side of the automobile, the rail curves on the passenger seat and passes above the rear left seat. It is provided near the rear rear window.

  Further, a vehicle wheelchair storage device for storing a wheelchair on the roof of the vehicle without storing the wheelchair in the vehicle compartment has been developed (for example, Patent Document 8).

JP 2004-236748 A JP 2005-329215 A JP 2005-102403 A JP 2000-108770 A JP 2009-18689 A JP 2006-102214 A Japanese Patent Laid-Open No. 10-129335 Japanese Patent Laid-Open No. 11-20554

  By the way, when a wheelchair user himself / herself drives a car, it is necessary to transfer between the wheelchair seat and the car seat. However, the space between the car seat and the vehicle body is considerably large for the wheelchair user. There is a gap. Therefore, it is difficult for the wheelchair to approach to the side of the seat. Also, the wheelchair user cannot easily transfer because the body posture such as the position of the pillar relative to the seat and the size of the opening of the door are limited.

  In addition, in an automobile such as a minivan where a seat is arranged at a high position, the seat of the automobile is at an extremely high position as seen from a wheelchair seat. Therefore, it is extremely difficult to transfer from the wheelchair to the car seat and, conversely, from the car seat to the wheelchair.

  In this regard, as described above, since the transfer board is attached to the side of the seat, it is possible to reduce the difficulty of transfer due to the gap between the seat and the vehicle body. However, it must be designed so that the transfer board can be foldably attached to the seat frame. In addition, since a transfer board cannot be retrofitted, a new dedicated seat must be purchased. Furthermore, when the transfer board is attached to the side of the seat, since the upper surface of the transfer board is higher than the seat, the healthy person must get over and get on and off the transfer board. The board becomes an obstacle.

  In the case of a car such as a minivan where the seat is placed at a high position, even if the transfer board is attached to the seat and the seat can be moved up and down in the passenger compartment, the seat and the transfer board can be It is physically difficult to lower the height of the sheet. That is, since there is a height difference between the wheelchair seat and the car seat, the difficulty in transferring between the wheelchair and the car is not solved for the wheelchair user.

  In this regard, in the techniques disclosed in Patent Documents 1 and 2, since the vehicle seat and the wheelchair are dedicated products, the vehicle and the wheelchair have to be redesigned with poor versatility, and cannot be retrofitted to the automobile. You must purchase a new wheelchair. The transfer assist device disclosed in Patent Document 3 can be applied to ordinary automobiles and wheelchairs, but cannot be transferred by wheelchair users themselves.

  Next, inconvenience when the wheelchair user himself / herself stores the wheelchair in the passenger compartment will be described. Usually, when a wheelchair user drives a car alone, the wheelchair user himself / herself needs to store the wheelchair in the car. When a wheelchair is stored in and taken out of a vehicle, a wheelchair user is more labor-intensive than a normal person. Therefore, storage and removal of the wheelchair from the vehicle should be as effortless and effortless as possible. In particular, in a car such as a minivan where the seat is located higher than the general one, the state where the wheelchair is placed on the ground is extremely low when viewed from the vehicle seat, and far from the vehicle seat. Exists. Therefore, even if a person sitting on the vehicle seat attempts to store the wheelchair in the vehicle by human power, the hand does not reach the wheelchair and is forced to lean down.

  In the apparatus disclosed in Patent Document 7, when the wheelchair is stored or taken out from the vehicle, the driver must change his / her posture greatly because the wheelchair moves over the driver's seat. Moreover, since it is necessary to knock down the seat back of the driver's seat at the time of storage, it is not suitable when a wheelchair user drives a car by himself. When this apparatus is assembled and mounted on a vehicle, it is necessary to correct the storage locus in the passenger compartment, that is, the rail shape, depending on the vehicle type. When the shape of the rail becomes complicated, the unit price of the rail itself increases. Moreover, since parts such as rails are always arranged above the driver's seat, the degree of freedom of driving operation is not high. Furthermore, in this apparatus, since the wheelchair is not fixed and is stored, the wheelchair hits the automobile interior part.

  The device disclosed in Patent Document 5 is an improvement of the device disclosed in Patent Document 4, but it is necessary to hook the wheelchair onto the storage device after the wheelchair is stored in the vehicle, so that the arm is inconvenient. Therefore, it is extremely difficult for a wheelchair user who is difficult to turn the upper body and turn backward.

  Furthermore, the apparatuses disclosed in Patent Documents 4 to 7 have a problem that the wheelchair cannot be stored in the vehicle compartment in a compact manner. For example, in the apparatus disclosed in Patent Document 4, a guide rail is disposed from the right seat to the left seat in the second row of seats in the vehicle width direction, and the second row seat can be effectively used. Can not. In that regard, in Patent Document 5, a person can be seated on the left seat of the second row seats. However, the third row sheet cannot be used effectively.

  In view of the above-described problems, the present invention solves the difficulty of transfer due to a horizontal gap between a vehicle seat and a wheelchair seat and a difference in height, and even a wheelchair user can place a wheelchair in a vehicle interior. It is a first object of the present invention to provide a wheelchair storage device that can be easily stored.

  In addition, the present invention provides a vehicle in which a wheelchair storage device that can carry in and out a wheelchair or assist a wheelchair user to transfer between a wheelchair and a vehicle seat is compactly attached. Second purpose.

In order to achieve the first object, a wheelchair storage device according to the present invention has wheelchair mounting means for a wheelchair to enter, an arm and a rotation mechanism for rotating the arm, and wheelchair mounting means via a vehicle opening. Equipped with a moving mechanism for loading and unloading the vehicle, and a transfer auxiliary seat for assisting transfer between the wheelchair and the vehicle, and a mounting member that is rotated by a power source is attached to the tip of the arm. The means is attached to the attachment means, the auxiliary seat for transfer is attached to the side of the attachment member opposite to the side where the wheelchair mounting means is disposed, and the orientation of the wheelchair mounting means and the auxiliary seat for transfer is changed by rotation of the attachment member. change. Furthermore, it is preferable that the wheelchair mounting means is provided with a pair of rails whose interval can be varied. It is possible to fold a wheelchair placed in a wheelchair mounting means or to deploy a folded wheelchair.

  In order to achieve the second object, the vehicle according to the present invention is characterized in that the wheelchair storage device according to the present invention is a vehicle attached to the rear floor of the front row seat, and the vehicle opening is a rear door. To do.

  ADVANTAGE OF THE INVENTION According to this invention, a wheelchair user can get on a wheelchair mounting means, riding in a wheelchair, and can transfer between a wheelchair and a vehicle seat. When there is a height difference between the wheelchair and the vehicle seat, the transfer mechanism is easily operated by operating the moving mechanism. In particular, when a transfer assisting seat is attached to the wheelchair mounting means, the wheelchair mounting means equipped with the transfer assisting seat can be carried in and out of the vehicle opening with a single moving mechanism. Since it is arranged in a necessary area when necessary, it is possible to reduce a gap in both the horizontal direction and the height direction between the vehicle seat and the wheelchair seat.

In the first embodiment of the present invention, the parallel link arm 40 and the rotation mechanism 50 constitute a moving mechanism 110.

  As shown in FIG. 1, the wheelchair storage device 10 is attached to the vehicle floor on the front row seat 2 side between the front row seat 2 and the rear row seat 3 of the vehicle 1. At the time of this attachment, it is not necessary to provide a new hole in the vehicle using a bolt hole or the like for assembling the front row seat 2 and the rear row seat 3 to the vehicle 1. In the first embodiment of the present invention, as shown in FIG. 1, it is assumed that the driver of the vehicle 1 is a user of the wheelchair 5, and the wheelchair storage device 10 is arranged behind the driver's seat. Yes. In the example shown in FIG. 1, the rear seat 3A of the driver's seat is flipped up. However, the present embodiment is not limited to this, and the rear seat 3A itself may be removed and the rear seat 3A may not be installed, and even if the rear seat 3A is not flipped up, the wheelchair may be You may make it accommodate on 3A.

[Parallel link arm and rotation mechanism]
The parallel link arm 40 and the rotation mechanism 50 shown in FIG. 2 will be described in detail. As shown in FIG. 3, the parallel link arm 40 has a distal end side directed outward in the vehicle width, and the distal end side is provided to protrude from the opening 60 </ b> A of the main body case 60.

  The parallel link arm 40 rotates the upper arm member 41A, the lower arm member 41B, and the upper arm member 41A and the lower arm member 41B while maintaining the postures of the upper and lower arm members 41A, 41B on the distal end side. It consists of four pivot shafts 42A, 42B, 43A, 43B that are movably supported. That is, the four rotation shafts 42A, 42B, 43A, and 43B are arranged at positions that form parallelograms, and the parallel link arm 40 constitutes a four-node parallel link.

  The upper two rotation shafts 42A and 42B are penetrated to the distal end sides of the upper arm member 41A and the lower arm member 41B, respectively. As shown in FIG. 3, the rotating shafts 42A and 42B are provided in a box 44. In the box 44, the direction changing means 70 for supporting the transfer auxiliary seat 20 and the wheelchair mounting means 30, as will be described later. Is attached. An opening is formed in the corner portion 44 </ b> A of the box 44. The distal end sides of the upper arm member 41A and the lower arm member 41B are inserted into the openings.

  The lower two rotation shafts 43A and 43B are penetrated to the rotation base end sides of the upper arm member 41A and the lower arm member 41B, respectively. As shown in FIG. 3, the rotation shafts 43 </ b> A and 43 </ b> B are provided in a main body case 60, and the main body case 60 accommodates a rotation mechanism 50 as will be described later.

  The main body case 60 has an opening 60A at one corner, and the rotation base end sides of the upper arm member 41A and the lower arm member 41B are inserted into the opening 60A. The main body case 60 is fixed to the vehicle compartment floor surface by the installation bracket 62 so that the opening 60A faces the vehicle width outside, and in the example shown in FIG. Rotating shafts 43A and 43B are bridged to the front and rear wall portions 63A and 63B in the main body case 60.

  The rotation shafts 43A and 43B are inserted through the rotation base points of the upper arm member 41A and the lower arm member 41B. Both the upper arm member 41A and the lower arm member 41B may adopt a turnbuckle method so that the length in the longitudinal direction can be adjusted.

  Here, the rotating shafts 42A, 42B, 43A, 43B are rotatably attached to the upper arm member 41A, the lower arm member 41B, and the rotating shafts 42A, 42B, 43A, 43B are the box 44, the body case. 60 may be fixed. On the contrary, the rotating shafts 42A, 42B, 43A, 43B are fixed integrally with the upper arm member 41A, the lower arm member 41B, and the rotating shafts 42A, 42B, 43A, 43B rotate around the box 44 and the body case 60. It may be movably attached.

  The rotation mechanism 50 is rotated, for example, around the rotation shaft 43B, whereby the entire parallel link arm 40 is rotated. Various configurations of the rotation mechanism 50 are conceivable. For example, as shown in FIG. 3, an actuator main body 51A, an actuator 51B that moves linearly from the actuator main body 51A, a base of the actuator 51B, and the lower arm member 41B. It can comprise from the lever 53 as a transmission member provided between end sides. The linear movement of the actuating portion 51B may be converted into a rotational motion of the lever 53 and transmitted to the parallel link arm 40. The lever 53 and the operating part 51B are connected by a rotating shaft 52.

  More specifically, the actuator main body 51A is arranged so that the operating portion 51B moves linearly in the vehicle width direction, and the rotary shaft 61 is bridged to the front and rear wall portions 63A and 63B of the main body case 60. One end of the actuator body 51 </ b> A is fixed to 61. A rotating shaft 52 is provided on the operating portion 51 </ b> B substantially parallel to the rotating shaft 43 </ b> B, and the operating portion 51 </ b> B is connected to the lever 53 by the rotating shaft 52. The rotating shaft 52 is not fixed to the main body case 60. The operating portion 51B linearly moves as the operating portion 51B extends from the actuator main body 51A and is immersed. Then, the actuator main body 51A swings with respect to the actuator fixed shaft which is the rotation shaft 61, and the cam-shaped lever 53 as a transmission member rotates around the rotation shaft 43B. Then, the upper arm member 41A and the lower arm member 41B rotate around the rotation shafts 43A and 43B, respectively.

  Here, the relationship between the lower arm member 41B and the lever 53 as a transmission member will be described. As shown in FIG. 3, the lever 53 has one lever 53A and the other lever 53 facing each other across the lower arm member 41B. A pair of levers 53B may be configured, or although not shown, one cam may be provided on the same surface as the axis of the lower arm member 41B. Here, the lever 53 as a transmission member is attached to the lower arm member 41B by welding or the like so as to form a predetermined obtuse angle with the lower arm member 41B.

  FIG. 4 is a diagram schematically showing the operation of the parallel link arm 40 by the rotation mechanism 50. In the rotating mechanism 50, for example, as described above, the lever 53 as a transmission member is fixed to the base end side of the lower arm member 41B by welding or the like, and the actuator 51 is lying substantially parallel to the vehicle width direction. The actuator body 51 </ b> A is supported by the rotation shaft 61 on the opposite side of the lever 53, and the operation portion 51 </ b> B is supported by the rotation shaft 52 in the vicinity of the lower end of the lever 53.

  Since the rotation mechanism 50 has the above-described configuration, the operating portion 51B of the actuator 51 extends or retracts from the actuator body 51A in the vehicle width direction and reciprocates in the direction of arrow A in FIG. Then, the lever 43 rotates together with the rotation shaft 52 in the direction of the arrow B in the figure with respect to the rotation shaft 43B. At the same time, the upper arm member 41A and the lower arm member 41B rotate around the rotation shafts 43A and 43B, respectively. Therefore, the upper arm member 41A and the lower arm member 41B rise or fall. At that time, the box 44 rotates as indicated by an arrow C, but keeps the same posture regardless of the inclination angles of the upper arm member 41A and the lower arm member 41B. A dotted line, a solid line, and a two-dot broken line indicate how the lever 53, the upper arm member 41A, the lower arm member 41B, and the box 44 are moved by the rotation mechanism 50.

  The rotation mechanism 50 is not limited to the illustrated form, and a gear may be interposed. The operating part 51B may be operated by either air pressure or hydraulic pressure. Further, although not shown, the rotation mechanism 50 includes an electric motor and rotates the upper arm member 41A and the lower arm member 41B around the rotation shaft 43B with a reduction gear such as a gear interposed. It may be.

[Rotation of parallel link arm by pivot mechanism]
The rotation of the parallel link arm 40 by the rotation mechanism 50 will be described with reference to FIG. The rotation mechanism 50 rotates the upper arm member 41A and the lower arm member 41B around an axis extending in the vehicle front-rear direction. As shown in FIG. 4, in the rotation mechanism 50, the actuator main body 51A is installed in a direction extending along the vehicle width direction, and the rotation shafts 61, 43A, and 43B do not change positions, and the operation unit 51B. Is extended or retracted from the actuator main body 51A, and the lever 53 as a transmission member rotates around the rotation shaft 43B corresponding to the operation.

  As described above, since the lower arm member 41B is fixed to the lever 53 as the transmission member so as to form a predetermined obtuse angle, the parallel link arm 40 rises so that the parallel link arm 40 warps as the lever 53 rotates. (The state shown by a dotted line in FIG. 4), the parallel link arm 40 falls down as if bowing (a state shown by a two-dot broken line in FIG. 4). At this time, since the upper and lower arm members 41A, 41B form a four-joint parallel link by the rotation shafts 42A, 42B, 43A, 43B, the box 44 rotates while keeping the horizontal as viewed from the main body case 60. .

[Wheelchair mounted means]
The wheelchair mounting means 30 shown in FIG. 2 will be described in detail. The wheelchair mounting means 30 includes a pair of rails 31 into which the auxiliary wheels and wheels of the wheelchair 5 enter, and a telescopic connecting portion 32 that connects the pair of rails 31.

  The pair of rails 31 includes a left rail 31L and a right rail 31R that are separated from each other in the vehicle width direction of the wheelchair 5. Each of the left rail 31L and the right rail 31R includes a partition portion 33 so that the auxiliary wheel (also referred to as “front wheel”) and the wheel of the wheelchair 5 are not detached. The partition portion 33 includes left and right side wall portions 33a and 33b and a restraining portion 33c except for either the front or rear (the rear side in the illustrated example) so that the wheelchair 5 can enter and withdraw. Most of the bottom portions 34 of the left rail 31L and the right rail 31R are horizontal in the front-rear direction, but the front and rear sides where the partition portion 33 is not provided are inclined so that there is no step with the ground. . Since the wheelchair 5 is withdrawn / retracted from the left and right rails 31L, 31R to the rear side, the restraining portion 33c serves as a stopper on the front side. Furthermore, flexible pads 35L and 35R are attached to the left side wall portion 33a of the left rail 31L and the right side wall portion 33b of the right rail 31R so as to face each other. The function of the pads 35L and 35R will be described. As will be described later, the pair of rails 31 has a narrower left and right interval due to the reduction of the connecting portion 32, and the wheelchair 5 is folded. At that time, the pads 35L and 35R press the wheel of the wheelchair 5 from the left and right with the other side wall portions 33b and 33a, and fix the wheelchair 5 so as not to move. Although it is sufficient that at least one pad 35L, 35R is attached to each of the pair of rails 31, the pads 35L, 35R may be provided on each of the pair of rails 31, respectively.

  As shown in FIG. 2, the connecting portion 32 is provided between the pair of rails 31 and supports the right rail 31R. A plurality of connecting portions 32 are provided between the pair of rails 31. FIG. 5 is a cross-sectional view of the connecting portion shown in FIG. As shown in FIG. 5, the connecting portion 32 is provided with a plurality of connecting members 32a, 32b, 32c having different cross-sectional dimensions on the same axis, and is extendable in the axial direction. Specifically, the left end side of the second connecting member 32b is inserted on the right end side of the first connecting member 32a, and the left end side of the third connecting member 32c is inserted on the right end side of the second connecting member 32b. . One of the first to third connecting members 32a, 32b, and 32c is inserted into the other and connected to the end so as to correspond to a locking portion. For example, a claw is provided on the shaft side as an engaging portion at the right end portion of the first connecting member 32a as an end portion on the insertion side, and a left end portion of the second connecting member 32b as an end portion on the inserting side. Are provided with hooks on the outer peripheral side as locking portions. The connection relationship between the right end portion of the second connecting member 32b and the third connecting member 32c is the same.

  The changing means 36 for changing the distance between the left rail 33L and the right rail 33R includes an actuator main body 36a as a power source and an operating portion 36b protruding and retracting from the actuator main body 36a. The changing means 36 is disposed in a direction intersecting with the pair of rails 31 between the one connecting portion 32F and the other connecting portion 32R. Specifically, the actuator main body 36a is attached to one connecting portion 32F of the left rail 31L via a bracket so as to be swingable about the vertical axis. The operating portion 36b is attached to the other connecting portion 32R of the right rail 31R via a bracket so as to be swingable about the vertical axis. The expansion / contraction means as the changing means 36, that is, the direction in which the actuator is disposed is not limited to the example shown in FIG. Good.

  The actuating part 36b appears and disappears from the actuator main body 36a, and the length of both ends of the changing means 36 expands and contracts. For example, the actuator 36b extends from the actuator body 36a, and the right rail 31R is pushed obliquely from the attachment position of the changing means 36 to the left rail 31L. However, a pair of connecting portions 32 are provided in parallel in the front-rear direction. Therefore, when the operating portion 36b extends from the actuator main body 36a, the right rail 31R increases the interval with the left rail 31L while being parallel to the left rail 31L. At this time, as the distance between the left and right rails 31L and 31R increases, the changing means 36 has the tip of the operating portion 36b attached as if the portion where the one end of the actuator main body 36a is attached as the central axis. The part where it is swaying. The same applies to the case where the actuator 36b is immersed in the actuator body 36a. Thereby, as described later, after the wheelchair user P gets on the pair of rails 31 while riding on the wheelchair 5 and the wheelchair user P transfers to the front row seat 2, the wheelchair 5 can be folded and unlocked. To do. In this state, when the changing means 36 expands and contracts, the right rail 31R approaches the left rail 31L, and the distance between the pair of rails 31 is narrowed. At that time, pressure is applied to the right wheel of the wheelchair 5 so as to approach the left wheel side. As a result, the wheelchair 5 is folded.

[Direction change mechanism]
The wheelchair mounting means 30 is attached to the moving mechanism 110 via the direction changing mechanism 70. The direction changing mechanism 70 includes a power source, a rotating shaft member that is rotated by the power source, and various attachments for attaching the rotating shaft member to the wheelchair mounting means 30. Hereinafter, the case where the moving mechanism 110 is configured to include the parallel link arm 40 and the rotating mechanism 50 as described above will be described as an example.

  As shown in FIGS. 2 and 4, an electric motor 72A as a power source is provided in the box 44 on the distal end side of the parallel link arm 40, and the electric motor 72A is arranged in parallel along the vertical axis. The rotation shaft member 72B is rotated forward and backward. An attachment 71 is attached to the rotation shaft member 72B. On the other hand, the mounting member 73 is erected from, for example, the side wall portion 33a of the left rail 31L of the pair of rails 31, and a plurality of through holes 73a are provided at the rear upper end portion of the mounting member 73. A pair of mounting holes are formed in the side surface of the attachment 71. Among the plurality of through holes 73a with respect to the pair of mounting holes, an appropriate pair is selected by combining the positional relationship with the moving mechanism 110, the size of the wheelchair 5 to be mounted, and further the positional relationship with the front row seat 2. The stopper 73b is inserted into the through hole 73a, and the attachment member 73 is attached to the parallel link arm 40 via the attachment 71.

  The direction changing mechanism 70 not only simply attaches the wheelchair mounting means 30 to the moving mechanism 110 but also changes the direction of the pair of rails 31 in the wheelchair mounting means 30 with respect to the moving mechanism 110. Specifically, when the electric motor 72A rotates forward, the pair of rails 31 is changed from the vehicle width direction to the vehicle front-rear direction, and when the electric motor 72A reverses, the pair of rails 31 move from the vehicle front-rear direction to the vehicle width direction. Change to Note that “forward rotation” means clockwise when viewed from the output shaft side, and “reverse rotation” means counterclockwise when viewed from the output shaft side.

[Modified example of wheelchair mounting means]
6 is a view showing a modification of the wheelchair mounting means 30 shown in FIG. 2, FIG. 7 (A) is a view showing an example of a connection mode between the left rail 31L and the changing means 37, and FIG. It is a figure which shows an example of the connection aspect of the rail 31R and the change means 37. FIG. FIG. 2 differs from FIG. 2 in the change means 37 in the wheelchair mounting means 30 and related points. In FIG. 6, the changing means 37 includes an electric motor 37a as a power source and a swing lever 37b swinging by the electric motor 37a. The changing means 37 is disposed in a direction intersecting with the pair of rails 31 between the one connecting portion 32F and the other connecting portion 32R. Specifically, a bracket 37d is attached to one connecting portion 32F of the left rail 31L, an electric motor 37a is attached to the bracket 37d, and one end of the swing lever 37b is connected to the electric motor 37a via a bearing 37c. It is installed. The electric motor 37a swings while supporting one end of the swing lever 37b. Therefore, the changing unit 37 may be called a swinging unit. The way of connecting the changing means 37 and the left rail 31L is not limited to that shown in FIG. 7A, and any mode is acceptable as long as the swing lever 37b can be swung by a power source such as an electric motor 37a. Good.

  On the other hand, as shown in FIG. 7B, a slide mechanism 38 is provided on the side wall 33 a of the right rail 31 </ b> R, and the swing lever 37 b is slid by the slide mechanism 38. Specifically, a slide rail 38a is attached to the side wall portion 33a of the right rail 31R along the right rail 31R, and a slider 38c is attached to the slide rail 38a so as to be able to travel via a bearing 38b. The tip of the moving lever 37b is attached, and the slider 38c and the swinging lever 37b are fixed by a stopper 37d. When the swing lever 37b swings, the slider 38c moves on the slide rail 38a by the slider mechanism 38, and the right rail 31R approaches or moves away from the left rail 31L in parallel. In addition, the connection mode between the right rail 31R and the changing unit 37 may be any mode as long as the tip of the swing lever 37b included in the changing unit 37 can slide along the right rail 31R.

[Transfer auxiliary seat]
Various types of attachment modes of the transfer auxiliary sheet 20 to the moving mechanism 110 and the type of the transfer auxiliary sheet 20 can be applied. In the first embodiment, as shown in FIG. 2, since the wheelchair mounting means 30 includes an attachment member 73, the transfer auxiliary seat 20 is attached to the front portion of the attachment member 73. The auxiliary seat 20 for transfer is attached to the attachment member 73 on the opposite side to the wheelchair mounting means 30. The transfer auxiliary seat 20 is preferably attached via a hinge, for example, so that it can be stored in the vehicle 1 together with the wheelchair 5 when not in use so that the transfer auxiliary seat 20 can be flipped up. Since the wheelchair storage device 10 shown in FIG. 1 includes the auxiliary seat 20 for transfer, it may be called a wheelchair storage / transfer auxiliary device. Even if the wheelchair storage device 10 itself does not include the auxiliary seat 20 for transfer, the wheelchair 5 and the front row seat 2 can be connected to each other using an unfolded auxiliary seat provided on the side of the front row seat 2 of the vehicle 1. You may transfer between.

  The transfer auxiliary seat 20 may be of any type as long as the wheelchair user can transfer between the wheelchair and the vehicle seat. In the first embodiment, the moving mechanism 110 is installed behind the driver's seat so that the parallel link arm 40 is arranged in the vehicle width direction, and a part of the front end side of the parallel link arm 40 can be projected to the outside of the vehicle. Yes. Therefore, the transfer auxiliary seat 20 is attached to a portion of the parallel link arm 40 that protrudes outside the vehicle. The auxiliary seat 20 for transfer makes it easier to transfer between the wheelchair and the vehicle seat when extending to the vicinity of the front end of the driver's seat. Therefore, the transfer auxiliary sheet 20 does not have to be a single sheet, and may be configured by connecting a plurality of sheets so as to be foldable. In a situation where the transfer auxiliary sheet 20 is not utilized, that is, in a situation where the transfer auxiliary sheet 20 is flipped up, if the size of the transfer auxiliary sheet 20 cannot be changed, the tip of the transfer auxiliary sheet 20 is This is because it interferes with the upper end of the sliding door opening of the vehicle, and even if the auxiliary seat 20 for transfer is housed in the vehicle interior, it extends to the vicinity of the ceiling in the vehicle interior, thus hindering the rear view. .

  In the first embodiment of the present invention, the wheelchair user P can easily transfer from the transfer auxiliary seat 20 to the front row seat 2 by raising the transfer auxiliary seat 20 to the height of the front row seat 2. . At that time, it is preferable that the transfer auxiliary sheet 20 is not limited to the front row sheet 2 side and the horizontal gap between the transfer auxiliary sheet 20 and the front row sheet 2 is minimized.

[Operation of wheelchair storage device]
The operation of the wheelchair storage apparatus 10 shown in FIG. 2 will be described. 8 and 9 are views showing the operation of the wheelchair storage device 10 shown in FIG. 2, and FIG. 8 (A) is a state where it is installed in the vehicle 1 and the moving mechanism 110 is not operated and is stored. FIG. 8B shows a state in which the moving mechanism 110 is activated and the distal end side of the parallel link arm 40 protrudes in the vehicle width direction, FIG. 9A shows a state in which the direction changing mechanism 70 is in operation, and FIG. It is a figure which shows the state which the change means 36 and 37 operate | moved. Fr, Up and RH indicate directions in the vehicle 1 shown in FIG.

  As shown in FIG. 8A, in the state where the wheelchair storage device 10 is attached to the vehicle 1 and the parallel link arm 40 is not operating, the parallel link arm 40 is warped and the wheelchair including the attachment member 73 is included. The mounting means 10 and the transfer auxiliary sheet 20 are supported. The rotation mechanism 50 rotates the parallel link arm 40 counterclockwise when viewed from the rear of the vehicle (the direction of the arrow shown in FIG. 8A). Then, as shown in FIG. 8 (B), the parallel link arm 40 falls as if bowing, and the front end side of the parallel link arm 40 protrudes from the opening of the vehicle.

  Thereafter, the direction changing mechanism 70 rotates the attachment member 73 about 90 degrees counterclockwise (in the direction of the arrow shown in FIG. 8B) in plan view. Then, as shown to FIG. 9 (A), a pair of rail 31 changes a direction from a vehicle width direction to the vehicle front-back direction. Next, the changing means 36 and 37 extend the connecting portion 32 as shown in FIG. Then, the right rail 31R moves away while keeping parallel to the left rail 31L, and the width of the pair of rails 31 is substantially the same as the width of the pair of wheels in the wheelchair 5, so that the wheelchair 5 can enter the pair of rails 31. It becomes.

  In this way, in order to store the vehicle from the state of projecting outside the vehicle into the vehicle interior, the reverse procedure may be taken.

  A procedure for transferring the wheelchair user P from the state of riding on the wheelchair 5 to the front row seat 2 by the wheelchair storage device 10 described above will be described. FIG. 10 to FIG. 12 are diagrams showing a series of flows in which a wheelchair user is transferred to a front row seat from a state of riding in a wheelchair and stores the wheelchair in the vehicle. FIG. FIG. 10B shows a state in which the wheelchair 5 is put on the wheelchair mounting means 10 by extending the parallel link arm 40. FIG. 11A shows a state in which the parallel link arm 40 is slightly rotated so that the height of the wheelchair 5 is substantially the same as that of the front row seat 2, and FIG. The state which changed to the front row sheet 2 using the auxiliary sheet 20 is shown. Moreover, FIG. 12 is a figure which shows the state accommodated in the vehicle 1 in the state which mounted the wheelchair. Fr, Up, and RH indicate directions in the vehicle 1 shown in FIG.

  As shown in FIGS. 1 and 9 to 11, for example, the wheelchair storage device 10 is attached to the rear side of the front row seat 2 that is a driver seat of the vehicle 1. In this state, the wheelchair user P is positioned almost right next to the slide door 1 </ b> A while the wheelchair 5 is on and opens the slide door 1 </ b> A. At that time, as shown in FIG. 8A, the wheelchair storage device 10 stands up so that the parallel link arm 40 is warped from the main body case 60, and the mounting member 73 is mounted almost directly above the main body case 60. The wheelchair mounting means 30 is disposed on the rear side of the member 73, and conversely, the transfer assisting seat 20 is flipped up to the front side, and stands up slightly toward the vehicle front side.

  In this state, the wheelchair user P operates, for example, the operation input unit 85 attached to the side of the seat and operates the rotation mechanism 50 so that the parallel link arm 40 is viewed from the front side of the vehicle. It rotates counterclockwise and the tip of the parallel link arm 40 protrudes outside the vehicle. In this state, the pair of rails 31 in the wheelchair mounting means 30 do not land on the ground or the like. Thereafter, the wheelchair user P operates the direction changing mechanism 70. Then, the direction of the pair of rails 31 is changed from the vehicle width direction to the vehicle front-rear direction. Thereafter, the wheelchair user P further operates the rotating mechanism 50 in the same manner as necessary, and the parallel link arm 40 rotates clockwise as viewed from the rear of the vehicle to land the pair of rails 31 on the ground. Then, as shown in FIG. 10B, the wheelchair user P gets on the wheelchair 5 on the pair of rails while riding on the wheelchair 5.

  Next, the wheelchair user P operates the operation input unit 85 to rotate the parallel link arm 40 counterclockwise as viewed from the rear of the vehicle as shown in FIG. Is raised to substantially the same height as the seat of the wheelchair 5 or to the height desired by the wheelchair user P. Thereafter, the wheelchair user P moves the auxiliary seat 20 for transfer to the vehicle 1 side to be in a substantially horizontal state, temporarily transfers to the auxiliary seat 20 for transfer, and operates the changing means 36 and 37. As a result, the right rail 31R comes close to the left rail 31L in parallel. At the same time, the wheelchair user P transfers to the front row seat 2 from the transfer auxiliary seat 20.

  In that case, the auxiliary seat 20 for transfer does not need to be the same height as the front row seat 2, and the vertical position can be adjusted within a range in which the wheelchair user P does not interfere with the transfer to the front row seat 2. This is because the wheelchair user P does not feel inconvenient to transfer to a low place, and conversely, some people do not feel inconvenient to transfer to a high place.

  As described above, as shown in FIG. 11B, the wheelchair user P moves to the front row seat 2, and when the connecting portion 32 is contracted by the changing means 36 and 37 and the distance between the left and right rails 31L and 31R is narrowed, the wheelchair 5 Is automatically folded. At that time, the lock mechanism for maintaining the deployed state of the wheelchair 5 is released.

  Thereafter, the wheelchair user P flips up the auxiliary transfer seat 2 as necessary, and then operates the operation input unit 85 to reversely operate the direction changing mechanism 70. Thereby, a pair of rail 31 changes direction from the vehicle front-back direction to the vehicle width direction.

  Next, the wheelchair user P operates the operation input unit 85 to rotate the parallel link arm 40 clockwise as viewed from the rear of the vehicle, and completely stores the wheelchair 5 in the vehicle 1 as shown in FIG. .

  In the above process, the case of transferring from the wheelchair 5 to the front row seat 2 has been described. Conversely, when transferring from the front row seat 2 to the wheelchair 5, almost the reverse steps may be taken.

  In the first embodiment of the present invention, the moving mechanism 110 includes a parallel link arm 40 with the transfer auxiliary seat 20 and the wheelchair mounting means 30 attached to the distal end side, and the parallel link arm 40 about an axis in the longitudinal direction of the vehicle width. And a rotating mechanism 50 that rotates. Therefore, the rotation mechanism 50 controls the rotation of the parallel link arm 40 so that the wheelchair mounting means 30 and the transfer auxiliary seat 20 are projected from the vehicle interior to the outside of the vehicle width, and the parallel link arm 40 stands up from the collapsed state. As the wheelchair mounting means 30 rises, the transfer auxiliary seat 20 can be lifted while approaching the side of the front row seat 2.

  Therefore, in a state where the parallel link arm 40 is collapsed, the wheelchair mounting means 30 and the transfer assisting seat 20 are projected outside the passenger compartment, so that the wheelchair user P temporarily transfers to the transfer assisting seat 20 and the wheelchair 5 is moved to the wheelchair. It can be easily accommodated in the mounting means 30. Further, when the parallel link arm 40 is rotated by the rotation mechanism 50 from this state, the wheelchair mounting means 30 and the transfer assisting seat 20 are raised, and the wheelchair user whose transfer assisting seat 20 is substantially the same height as the vehicle seat, for example. In a state where P is at a height that is easy to use, the transfer assisting seat 20 approaches the side of the front row seat 2 as compared with the state in which the wheelchair 2 is placed in the wheelchair mounting means 30, and the wheelchair user P assists in the transfer. It is possible to easily transfer from the seat 20 to the front row seat 2. When the wheelchair user P is transferred from the front row seat 2 of the vehicle 1 to the wheelchair 5, the difficulty of transfer due to the height difference between the vehicle seat and the wheelchair 5 is eliminated, and the clearance between the vehicle seat and the auxiliary seat 20 for transfer is reduced. By reducing, wheelchair user P can be easily transferred.

  Furthermore, the rotation mechanism 50 rotates the parallel link arm 40 in response to a signal input from a control unit (not shown). In the first state where the parallel link arm 40 is raised, the transfer auxiliary seat 20 and the wheelchair are mounted. In the second state in which the means 30 is accommodated in the vehicle compartment and the parallel link arm 40 is collapsed, the transfer auxiliary seat 20 and the wheelchair mounting means 30 are projected outward in the vehicle width direction, and the parallel link arm 40 is In the intermediate state between the state and the second state, the wheelchair mounting means 30 is levitated outside the passenger compartment, and the auxiliary seat 20 for transfer is either at the same level as the front row seat 2 or at a height above or below the front row seat 2. Accordingly, the horizontal distance of the auxiliary sheet 20 for transfer to the front row sheet 2 can be reduced.

  According to the vehicle of the first embodiment of the present invention, the function of storing the wheelchair 5 and the function of assisting the transfer between the wheelchair 5 and the front row seat 2 are compactly incorporated into one apparatus as the wheelchair storage apparatus 10. Since this device is attached to the rear floor surface of the front row seat 2 with the parallel link arm 40 facing outward in the vehicle width direction, the area required for the wheelchair storage device 10 in the vehicle compartment can be made as small as possible. Thereby, the rear row seat 3 on the side where the wheelchair storage device 10 is not installed and other rear row seats, for example, the third row seat can be effectively used.

  As described above, according to the first embodiment of the present invention, the parallel link arm 40 is arranged along the vehicle width direction, the rotation mechanism is provided on the base end side of the parallel link arm 40, and the parallel link arm is provided. The auxiliary seat 20 for transfer and the wheelchair mounting means 30 are attached to the front end side of 40 via a direction changing mechanism 70. That is, since these wheelchair storage devices 10 are attached to the rear side of the front row seats 2, the space becomes very compact and the space of the vehicle 1 can be used effectively.

  Since the wheelchair storage device 10 does not protrude in the height direction or the lateral direction and becomes very compact, the driver can easily check the rear. Since the wheelchair storage device 10 can be retrofitted regardless of the individual wheelchair 5 or the vehicle 1, there is no manufacturing cost, there is no need to modify the wheelchair 5 or the vehicle 1, and the wheelchair user P's favorite vehicle 1 or wheelchair 5 is preferred. Can be selected.

  Further, the rotation mechanism 50 controls the rotation of the parallel link arm 40, so that the wheelchair mounting means 30 and the transfer auxiliary seat 20 can be projected outwardly of the vehicle width, and the parallel link arm 40 is tilted. As the wheelchair mounting means 30 rises, the auxiliary seat 20 for transfer is raised to the height of the front row seat 2. At that time, the auxiliary seat 20 for transfer not only rises, but also approaches the vehicle 1 side, particularly the side of the front row seat 2, and a large gap does not occur between the front row seat 2 and the auxiliary seat 20 for transfer, The wheelchair user P can easily transfer between the auxiliary seat 20 for transfer and the front row seat 2.

  At this time, the direction and angle of rotation of the parallel link arm 40 by the rotating mechanism 50 are determined according to the type and size of the wheelchair 5 and the vehicle 1, the size of the auxiliary seat 20 for transfer, the degree of obstacle of the wheelchair user P, the height, and the like. In consideration of registration in the control unit, the wheelchair 5 can be accommodated and transferred with a single device in accordance with an input instruction from the wheelchair user P to the operation input unit 85.

  Note that the control unit is not essential, and a very simple circuit may be provided in which the power source is rotated forward and backward from the power source via the remote control switch. In this case, the wheelchair user P can stop the transfer auxiliary seat 20 and the wheelchair mounting means 30 at a desired height by operating the remote control switch at a position where the wheelchair user P wants to stop appropriately. The direction can be stopped in a predetermined direction.

  As described above, the auxiliary seat 20 for transfer is about the same height as the wheelchair and about the same height as the seat of the vehicle, and is further raised or lowered after stopping at each position, so that the wheelchair and the seat of the vehicle Height difference and gap are eliminated. In the first embodiment of the present invention, the case where the heights of the front row seat 2 of the vehicle and the seat of the wheelchair 5 are different is described. When the front row seat 2 is only slightly different from the seat of the wheelchair 5, the wheelchair 5 is placed on the left and right rails 31L and 31R while the left and right rails 31L and 31R are in contact with the ground. The rails 31 </ b> L and 31 </ b> R may be transferred from the seat of the wheelchair 5 to the front row seat 2 while being in contact with the ground. In this case, the left and right rails 31L and 31R function as a stepping board. When the wheelchair user P is transferred to the front row seat 2, the wheelchair mounting means 30 is lifted by the arm portion 40 of the moving mechanism 110, the wheelchair 5 is folded by narrowing the interval between the left and right rails 31L, 31R, and then the direction changing mechanism 70 is used. The wheelchair 5 is rotated clockwise in plan view and stored in the vehicle 1 while the wheelchair 5 is placed on the wheelchair mounting means 30.

  In the first embodiment of the present invention, as shown in FIG. 1, the wheelchair user P himself / herself drives as an example, but it is also effective when transferring from an wheelchair to an auxiliary seat. Further, in the vehicle 1 equipped with the wheelchair storage device 10 according to the first embodiment of the present invention, the driver's seat has not been changed at all, so that it is an obstacle when a healthy person drives or gets on and off. Such a part is not arranged around the front row sheet 2. These points also apply to other embodiments described later.

  In the first embodiment of the present invention, the moving mechanism 110 includes the parallel link arm 40 and the rotation mechanism 50. However, the present invention is not limited to this, and the parallel link mechanism 40 such as the parallel link arm 40 is not limited thereto. In addition, it may be configured by a rotation mechanism, a linear mechanism, or a combination of these mechanisms as described in other embodiments described later. This is because it is sufficient that the transfer auxiliary seat 20 and the wheelchair mounting means 30 can be carried into and out of the vehicle opening with a single moving mechanism. That is, the auxiliary seat 20 for transfer can be arranged in a necessary area when necessary to reduce the gap between the vehicle seat and the seat of the wheelchair 5 in the horizontal direction and the height direction, and is mounted on the wheelchair. If the means 30 can be taken in and out of the vehicle and the wheelchair on the ground can be accommodated in the vehicle, the problem of the present invention is solved.

  Therefore, even if the auxiliary seat 20 for transfer by the moving mechanism and the wheelchair mounting means 30 draw an arc-shaped locus in a substantially vertical plane as shown in the first embodiment, as shown in other embodiments described later. Even if a trajectory that is a combination of a first linear trajectory parallel to the vehicle width direction in a substantially vertical plane and a second linear trajectory parallel to the vertical direction on the first trajectory is drawn. Good. That is, the moving mechanism is configured such that the moving mechanism 110 is a combination of the parallel link arm 40 and the turning mechanism 50 as in the first embodiment, and the leading ends of the moving mechanisms 120 and 130 are as in the second and third embodiments. A combination of two rotating mechanisms, as in the fourth to sixth embodiments, may be configured such that the tips of the moving mechanisms 140 to 160 are a combination of two linear moving mechanisms.

A box 75 such as the box 44 shown in FIG. 3 is attached to a predetermined position of the bracket 124, and the electric motor 72 </ b> A is accommodated in the box 75. Since the auxiliary transfer seat 20, the wheelchair mounting means 30, and the direction changing means 70 are the same as those in the first embodiment, they are not shown in FIG.

  According to the second embodiment of the present invention, when the actuating portion 127b protrudes and retracts from the actuator main body 127a, the first arm portion 122b swings as if bowing and the gear 123 is moved by the belt or chain 125. In order to rotate, the bracket 124 rotates while maintaining a predetermined angle (for example, a horizontal state). Thereby, the direction changing mechanism 70 is provided via the box 75 attached to the bracket 124 at a predetermined position, and the transfer auxiliary seat 20 and the wheelchair mounting means 30 are attached via the direction changing mechanism 70, thereby The auxiliary seat 20 and the wheelchair mounting means 30 can be carried in and out of the vehicle opening.

[Fourth Embodiment]
FIG. 15 is a perspective view schematically showing a moving mechanism in the wheelchair storage device according to the fourth embodiment of the present invention. As shown in FIG. 15, the moving mechanism 140 in the fourth embodiment is a combination of two linear moving mechanisms 140A and 140B. One linear moving mechanism 140A realizes movement in the vehicle width direction, and the other The linear moving mechanism 140B realizes vertical movement in the vehicle height direction.
