Description

  The present invention relates to a vehicle structure in which a care seat can be installed in a vehicle interior.

  Here, the “care seat” is a seat prepared separately from a normal vehicle seat (standard vehicle seat) installed in the passenger compartment, and is compared to a normal vehicle seat. It is the sheet | seat comprised so that it might suit. For example, a seat that is detachably mounted on a cart part of a wheelchair used for nursing care is applicable.

An example of the vehicle structure is disclosed in Patent Document 1.
In the vehicle structure described in the same document, a seat (care sheet) that is detachably mounted on a wheelchair carriage can be detached from the carriage and carried into the vehicle compartment from outside the vehicle. Has been. As a means for bringing the wheelchair seat into the passenger compartment, an operation using a pair of arms whose front ends are engaging portions and a motor that supports the pair of arms and can reciprocate in a substantially horizontal direction. Means for installing a sheet carry-in / out device including a mechanism in the passenger compartment is employed. In a state where the wheelchair is placed close to the side of the vehicle, the pair of arms protrudes out of the vehicle toward the wheelchair and is submerged under the seat of the wheelchair, and then the pair of arms is moved to the vehicle interior side. By retracting, the seat can be supported and carried into the passenger compartment.
According to such a configuration, the wheelchair user can get into the vehicle while sitting on the wheelchair care seat, and the burden on the wheelchair user when getting into the vehicle can be reduced. it can.

  However, the prior art has room for improvement as described below.

1stly, the structure provided with the motor for reciprocating each of a pair of arm for supporting a care sheet in the state where it has one piece as an apparatus for carrying in / out a care sheet conventionally Is adopted. For this reason, the parts cost and manufacturing cost of the apparatus become expensive, and the productivity is poor. In addition, the overall weight is large.
Secondly, since the pair of arms for supporting the care sheet is provided in an independent form so as to be arranged in parallel at an appropriate interval, the care sheet is placed on the arms. Then, those stability is bad, and a backlash is produced in a sheet | seat. This gives anxiety to the person sitting on the seat.

  The present invention has been conceived under the circumstances as described above, and it is possible to perform the movement of the nursing care sheet in a stable state while simplifying the apparatus configuration and reducing the manufacturing cost. The subject is to provide a vehicle structure.

  In order to solve the above problems, the present invention takes the following technical means.

The vehicle structure provided by the present invention includes a seat installation portion that is provided in a vehicle interior and that can detachably install a predetermined nursing seat in the vehicle interior, and the vehicle from the vehicle interior in a predetermined first direction. It is possible to selectively set either a state of projecting out of the vehicle through the door opening of the vehicle or a state of retreating into the vehicle interior, and the care sheet is carried into and out of the seat installation unit from the outside of the vehicle The seat moving means includes at least a pair of sliding rails in which a sliding member is supported by a frame along the first direction. The pair of slide rails are arranged in a second direction intersecting the first direction with a space therebetween, and are connected to each other via a connecting member, whereby the pair of slide rails. Moving rail Preliminary the connecting member forms the plan view frame shape or plate shape, and characterized in that it is configured as a movable guide sheet that enables sliding the care sheet on said sliding member.
Here, as the sliding member, a rotatable roller can be used, and as the sliding rail, a roller rail in which a plurality of rollers are arranged in a row and supported rotatably on the frame can be used.

According to such a configuration, the following effects can be obtained.
First, as a means for supporting and moving the care sheet, a slide method is adopted, and the care sheet is slid on the sliding member. For this reason, compared with the device configuration described in Patent Document 1 in which the care sheet is supported by a pair of arms and this arm is moved by a motor, the overall configuration is simplified, and the component cost and manufacturing cost of the device are reduced. Can be made inexpensive. In addition, the weight can be significantly reduced.
Second, the sheet moving guide that supports the care sheet has a frame shape or a plate shape in which a pair of slide rails are connected via a connecting member, so that the strength of the sheet moving guide is increased. be able to. Moreover, since the row | line | column of a sliding member becomes a multiple row | line | column in the direction (said 2nd direction) cross | intersected with the direction to which a nursing sheet | seat is slid, the sheet | seat for nursing care is put on these sliding members of these multiple rows | lines. Can be placed in a stable state. For this reason, when the care sheet is slid and moved, it is possible to prevent the care sheet from being largely rattled and to prevent the person sitting on the care sheet from feeling uneasy.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

A vehicle structure C shown in FIG. 1 includes a seat mounting portion 11 installed in a passenger compartment 10 of a vehicle 1, a care seat mounting base 3, and a seat movement guide 4 attached to the care seat mounting base 3. I have.
The care sheet 5 in this embodiment is a seat for the wheelchair A and is detachable on the carriage unit 6 of the wheelchair A.
In the state where the nursing care seat mounting base 3 is mounted in the passenger compartment 10, this nursing care seat mounting base 3 corresponds to an example of the seat setting section referred to in the present invention.

  The vehicle 1 has a structure in which, for example, the passenger seat side is center pillar-less, and the door opening 12 on the passenger seat side can be made large (in FIG. 1 and FIG. 2, the front seat on the passenger seat side). The side door is omitted). As will be described later, this facilitates the work of bringing the care sheet 5 and the person seated on it into the passenger compartment 10 from outside the vehicle.

  The seat attachment portion 11 is a portion that is originally installed in the vehicle compartment 10 in order to install the normal vehicle seat 2 in the vehicle compartment 10, and is specifically a seat rail that is attached on the floor 13. More specifically, the seat attachment portion 11 is a movable rail that is slidably fitted in the longitudinal direction with respect to a fixed rail 11a fixed to the floor 13 among the seat rails. As will be described later, the seat attachment portion 11 is not slid when the care seat attachment base 3 is attached. The normal vehicle seat 2 is configured as a normal passenger seat of the vehicle 1 and can be detachably attached to the seat attachment portion 11 using means such as bolts.

  As described above, the care sheet 5 is a detachable sheet on the carriage unit 6 of the wheelchair A. However, in order to facilitate understanding of the vehicle structure C of the present embodiment, the overall configuration of the wheelchair A is also set. explain. As shown well in FIG. 5, the cart unit 6 of the wheelchair A includes a base 61 to which a plurality of traveling wheels 60 are attached, a sheet placing unit 62 on which the care sheet 5 is placed, and the seat placing. An elevating mechanism 63 for changing the height of the part 62 is provided. The elevating mechanism 63 is a pantograph mechanism configured such that the vertical height changes by rotating the handle 64, for example. Therefore, by operating the handle 64, the height of the sheet placing portion 62, and hence the height of the care sheet 5 can be changed. As a means for changing the height of the sheet placing portion 62, for example, another mechanism using a gas cylinder or the like can be employed.

  The care seat 5 includes a seat belt device 50, a footrest 51, a handle portion 53 that is attached to the back surface of the seat back 52 and is used when the wheelchair A is pushed. On the lower surface side of the seat cushion 54 of the care sheet 5, there is provided a roller receiving plate portion 55 placed on a pair of roller rails 65 attached to the upper surface of the seat placement portion 62 of the carriage portion 6, A pair of first and second downward convex guide portions 56a and 56b is also provided. The roller rail 65 is configured such that upper portions of a plurality of rollers 65b disposed in a frame 65a having a rectangular frame shape in plan view and rotatably supported are projected upward from the frame 65a. Such a basic configuration is the same for the other roller rails 31 and 40 described later.

Since the care sheet 5 is placed on the roller rail 65, the care sheet 5 can be smoothly slid to one side of the carriage portion 6 indicated by the arrow Na in FIG. Is possible. Although illustration is omitted, a lock mechanism is provided to prevent the care sheet 5 from being carelessly detached in the direction of the arrow Na during normal use of the wheelchair A. The care sheet by this lock mechanism is provided. The movement blocking lock state 5 can be appropriately released by a specific manual operation. The care sheet 5 is prevented from being separated from the carriage unit 6 in the direction opposite to the arrow Na by the stopper wall 66. The pair of first downward convex guide portions 56a is located between the pair of upward convex guide portions 67 provided on the sheet placing portion 62, and is a pair of second downward convex shapes. The guide portion 56b is in a position to sandwich the pair of roller rails 65 on both sides thereof. Such a structure prevents the care sheet 5 from being unjustly displaced in the front-rear direction of the carriage unit 6.

  1 and 2, the care seat mounting base 3 can be detachably attached to the seat mounting portion 11 in the passenger compartment 10 using means such as bolting. As shown well in FIG. 4, the nursing seat mounting base 3 is provided on the upper surface of a rectangular block-shaped base portion 30 that can be arranged on the floor 13, for example, with a sheet moving guide 4 and a pair of fixed rollers. The rail 31, a pair of upward convex guide portions 32, and a stopper wall 33 are provided.

  The sheet moving guide 4 has a structure in which the tip portions of a pair of roller rails 40 are connected via a crank-shaped connecting member 41, and the overall planar view shape is a substantially U-shaped frame shape. Is. Each roller rail 40 corresponds to an example of a “sliding rail” in the present invention, and the plurality of rollers 40b that are constituent members correspond to an example of a “sliding member” in the present invention. The plurality of rollers 40 b of each roller rail 40 are arranged in a line in the horizontal direction of the base portion 30, and the pair of roller rails 40 are arranged with a space in the front-rear direction of the base portion 30. .

  The sheet moving guide 4 can be slid back and forth in the direction indicated by the arrow Nc. As a means for that purpose, for example, a means is adopted in which a protrusion 40c connected and fixed to one side of each roller rail 40 is slidably fitted into a slide guide rail 49 having a substantially C-shaped cross section. 2 and 3, when the care seat mounting base 3 is mounted on the floor 13 in the passenger compartment 10, the seat movement guide 4 is opened to the door of the vehicle 1. It can be set in a state of protruding outside the vehicle via the portion 12. In such a set state, as will be described later, it is possible to carry the care sheet 5 from the wheelchair A into the passenger compartment 10 using the seat movement guide 4.

  The connecting member 41 of the sheet moving guide 4 is rotatable as shown by an arrow Nd in FIG. When the seat movement guide 4 is further advanced from the state shown in FIG. 6 to the state shown in FIG. 7, the distal end portion of the seat movement guide 4 is disposed on the upper surface of the seat placement portion 62 of the wheelchair A. At the same time, the connecting member 41 can be positioned between the engaging convex portion 62 a on the upper surface portion of the sheet placing portion 62 and the pair of upward convex guide portions 67. With this setting, the sheet placement unit 62 and the sheet movement guide 4 can be positioned in the lateral width direction of the sheet placement unit 62. Based on the engagement of the connecting member 41 with the engaging convex portion 62a, the sheet moving guide 4 is prevented from being inadvertently detached from the sheet placing portion 62 in the direction of the arrow Ne. Further, when the connecting member 41 contacts the upward convex guide portion 67, the sheet moving guide 4 is also prevented from excessively moving in the direction opposite to the arrow Ne with respect to the sheet placing portion 62. This also prevents inadvertent misalignment between the seat movement guide 4 and the wheelchair 6 of the wheelchair A.

  In FIGS. 6 and 7, the inclined surfaces 69a of the pair of fixing members 69 provided on the sheet placing portion 62 are moved when the sheet moving guide 4 approaches and comes into contact with the inclined surfaces 69a. This is a part for guiding the position of the sheet moving guide 4 to a predetermined appropriate position. The inclined surface portion 59 in the vicinity of the lower surface portion of the care sheet 5 shown in FIG. 6 smoothly transfers the care sheet 5 when it is transferred from the sheet placement portion 62 onto the sheet movement guide 4. It is a part for making it.

In FIG. 4, the pair of fixed roller rails 31 of the nursing care seat mounting base 3 receives the load when the nursing care seat 5 moves on the nursing care seat mounting base 3. This is for smoothly sliding the care sheet 5 on the base 3. When the care sheet 5 is transferred onto the care sheet mounting base 3, many parts of the sheet movement guide 4 protrude outward from the care sheet mounting base 3, and the care sheet Although it is difficult to support the care sheet 5 that has traveled up to the mounting base 3 by the sheet moving guide 4, the fixed roller rail 31 plays a role of supporting the care sheet 5 instead.

  As shown in FIG. 4B, when the care sheet 5 is transferred onto the care sheet mounting base 3, the pair of first downward convex guide portions 56 a of the care sheet 5 is a pair. It is located between the upward convex guide portions 32. Further, the pair of second downward convex guide portions 56 b of the care sheet 5 are positioned so as to sandwich the pair of fixed roller rails 31. This prevents the care sheet 5 from being displaced in the front-rear direction of the care sheet mounting base 3. The stopper wall 33 shown in FIG. 4A is a part for preventing the care sheet 5 from advancing more than a predetermined amount in the lateral width direction of the care sheet mounting base 3. Although illustration is omitted, the care sheet 5 is carelessly moved to the outside of the vehicle in the state where the care sheet 5 is disposed on the care sheet attachment base 3. A locking mechanism is provided to prevent the above. The movement prevention lock state of the care sheet 5 by the lock mechanism can be appropriately released by a specific manual operation.

  Next, the operation of the vehicle structure C described above will be described.

  In FIG. 1, when the vehicle 1 does not need to have a so-called care specification, a normal vehicle seat 2 may be attached to the seat attachment portion 11 and installed in the passenger compartment 10. On the other hand, when the vehicle 1 is used as a nursing care specification, the nursing care seat mounting base 3 is attached to the seat mounting portion 11 after the normal vehicle seat 2 is removed from the seat mounting portion 11. According to such a setting state, the care sheet 5 of the wheelchair A can be carried into the passenger compartment 10 using the seat movement guide 4 and fixed on the care seat mounting base 3. Specifically, this operation is as follows.

  That is, first, as shown in FIG. 3, in a state where the wheelchair A is moved to the side of the vehicle 1, the seat movement guide 4 is slid so as to protrude out of the vehicle, and the tip portion thereof is seated on the seat placement portion of the wheelchair A. 62. When the height of the sheet placement unit 62 and the height of the sheet moving guide 4 do not match, the handle 64 may be operated to adjust the height of the sheet placement unit 62. As shown in FIG. 3, an optical sensor 99 for detecting an appropriate position of the wheelchair A is provided on the care seat mounting base 3, and the height of the seat placement portion 62 is adjusted when the height is adjusted. When the height becomes an appropriate height, it is also possible to adopt means for detecting this by the optical sensor 99 and notifying it with a buzzer sound or the like.

  When the leading end portion of the sheet moving guide 4 is placed on the sheet placing portion 62, as described with reference to FIG. 6 and FIG. It is possible to appropriately prevent misalignment, and it is possible to prevent the leading end portion of the sheet moving guide 4 from dropping from the sheet placing portion 62. After that, after releasing the locked state of the care sheet 5, while the person is seated on the care sheet 5 of the wheelchair A, the caregiver pushes the care sheet 5 with the hand on the sheet movement guide 4. After that, the sheet moving guide 4 is slid to be transferred onto the nursing care seat mounting base 3 in the passenger compartment 10. After the transfer, the care sheet 5 is locked, and the sheet movement guide 4 is slid back and returned to the original position on the care sheet mounting base 3.

Since the sheet moving guide 4 has a frame shape in which a pair of roller rails 40 are connected using a connecting member 41, the strength of the sheet moving guide 4 can be increased, and the plurality of rollers 40b are separated at appropriate intervals. Further, the care sheet 5 can be supported and guided stably. Therefore, the care sheet 5 and its seated person can be carried into the vehicle compartment 10 in a stable state without causing a large backlash.

  Contrary to the above, even when the care sheet 5 is carried out of the vehicle and returned to the carriage unit 6, the sheet movement guide 4 is projected outside the vehicle, and the leading end thereof is the sheet placement unit 62 of the carriage unit 6. Put it on top. Thereafter, the care sheet 5 is released from the locked state with respect to the care sheet mounting base 3, and then the care sheet 5 is pushed toward the cart unit 6 side. Accordingly, it is possible to appropriately move the care sheet 5 onto the sheet placement unit 62 using the sheet movement guide 4. In this case as well, a person may remain seated on the care sheet 5.

  When it is no longer necessary to make the vehicle 1 have a so-called welfare specification, the vehicle seat 2 is reattached to the seat attachment portion 11 by removing the care seat attachment base 3 from the seat attachment portion 11. Is possible. Thus, according to the vehicle structure C of the present embodiment, the normal vehicle seat 2 is installed in the passenger compartment 10, and the care seat 5 is replaced from the outside of the vehicle in place of the normal vehicle seat 2. It is possible to easily switch between a state where the vehicle can be carried into and out of the passenger compartment 10. Accordingly, flexibility and convenience can be improved. In addition, the care sheet 5 is moved manually, and for example, it is not necessary to incorporate a motor in the care sheet mounting base 3. Therefore, the overall manufacturing cost can be reduced and the weight can be reduced. It is possible to plan.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the vehicle structure according to the present invention can be modified in various ways within the intended scope of the present invention.

The sheet moving guide may be in the form of a plate in plan view, for example, instead of the frame shape in a U shape in plan view. The connecting member of the sheet moving guide is not limited to a wire shape or the like, and may be a member of another form such as a plate shape.
The “sliding member” and “sliding rail” referred to in the present invention are not limited to the roller 40b and the roller rail 40 described above. The sliding member referred to in the present invention may be, for example, a rotatable cylindrical shape or a spherical bearing shape such as a spherical shape, or a member having a smaller surface friction coefficient than the frame supporting the sliding member. For example, a corrugated plate or the like that can smoothly slide the care sheet may be used. This also applies to the other roller rails 31 and 65 of the above-described embodiment.

  In the above-described embodiment, the care sheet is carried in from the door opening on the side of the vehicle, but the present invention is not limited to this. For example, you may make it carry in / out to a vehicle interior from the door opening part (back door opening part) of a vehicle rear part. The position where the care sheet is attached is not limited to the position of the passenger seat.

The definition of the care sheet is as described at the beginning, and is not limited to the wheelchair seat.
When the vehicle is shipped from the factory, the vehicle seat does not necessarily have to be installed at a specific location in the passenger compartment. It can also be attached to a specific location in the passenger compartment. In this case, if necessary, in a car dealer or the like, an operation for removing a care seat mounting base, an operation for mounting a normal vehicle seat, or the like may be performed. The care seat mounting base or the vehicle seat for ordinary use does not need to be carried by the user of the vehicle, and may be configured to be sold, rented, or stored by an automobile dealer, for example.
