Description

The present invention relates to a vehicle structure in which a care sheet can be installed inside a vehicle.

Here, the "nursing care seat" is a seat prepared separately from the normal vehicle seat (standard vehicle seat) installed in the passenger compartment, and compared with the normal use vehicle seat. The sheet is configured to be suitable for. For example, a seat that is detachably attached to the trolley portion of a wheelchair used for nursing care is applicable.

As an example of a vehicle structure, there is one described in Patent Document 1.
In the vehicle structure described in the document, it is possible to detach a seat (care seat) that is detachably attached to the trolley portion of the wheelchair from the trolley portion, carry it in from the outside of the vehicle, and install it in the vehicle interior Has been done. As a means for loading the seat of the wheelchair into the passenger compartment, an operation using a pair of arms having distal ends as engaging portions and a motor that supports the pair of arms and can reciprocate in a substantially horizontal direction. A means for installing a seat loading/unloading device having a mechanism in a vehicle compartment is adopted. In a state in which the wheelchair is placed close to the side of the vehicle, the pair of arms are projected toward the outside of the vehicle toward the wheelchair, and after the arm is sunk under the seat of the wheelchair, the pair of arms are placed inside the vehicle interior By retracting, the seat can be supported and carried into the vehicle compartment.
With this configuration, the user of the wheelchair can get into the vehicle while sitting on the care sheet of the wheelchair, and the burden on the user of the wheelchair when getting into the vehicle can be reduced. it can.

However, in the above-mentioned prior art, there is room for improvement as described below.

Firstly, conventionally, as a device for loading and unloading a care sheet into and from a vehicle compartment, a configuration including a motor for reciprocating a pair of arms for supporting the care sheet in a cantilever state Has been adopted. Therefore, the component cost and manufacturing cost of the device are high, and the productivity is poor. In addition, the total weight becomes large.
Secondly, since the pair of arms for supporting the care sheet are provided in independent shapes so as to be arranged in parallel at appropriate intervals, the care sheet is placed on the arms. However, their stability is poor, and the sheet rattles. This gives the person sitting on the seat anxiety.

An elevating mechanism 63 for changing the height of the portion 62 is provided. The elevating mechanism 63 is a pantograph mechanism configured such that the vertical height is changed by rotating the handle 64, for example. Therefore, by operating the handle 64, it is possible to change the height of the seat placing portion 62, and thus the height of the care sheet 5. As the height changing means of the sheet placing portion 62, it is possible to employ another mechanism using a gas cylinder or the like.

The care seat 5 is provided with a seat belt device 50, a footrest 51, and a handle portion 53 that is attached to the back surface of the seat back 52 and is used when pushing the wheelchair A. On the lower surface side of the seat cushion 54 of the care sheet 5, a roller receiving plate portion 55 mounted on a pair of roller rails 65 attached to the upper surface of the seat mounting portion 62 of the carriage portion 6 is provided. A pair of first and second downward convex guide portions 56a and 56b are also provided. The roller rail 65 has a configuration in which the upper portions of a plurality of rollers 65b arranged in a frame 65a having a rectangular frame shape in plan view and rotatably supported are set so as to project above 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 rails 65, the care sheet 5 can be smoothly slid to one side of the carriage portion 6 indicated by an arrow Na in FIG. It is possible. Although illustration is omitted, a lock mechanism is provided to prevent the care sheet 5 from being unintentionally disengaged in the direction of the arrow Na during normal use of the wheelchair A. The care sheet using this lock mechanism is provided. The movement prevention lock state 5 can be appropriately released by a specific manual operation. The stopper wall 66 prevents the care sheet 5 from coming off the carriage 6 in the direction opposite to the arrow Na. The pair of first downward convex guide portions 56a are positioned so as to be interposed between the pair of upward convex guide portions 67 provided on the sheet placing portion 62, and have a pair of second downward convex shapes. The guide portions 56b are positioned so as to sandwich the pair of roller rails 65 on both sides thereof. Such a structure also prevents the care sheet 5 from being unjustly displaced in the front-rear direction of the carriage 6.

1 and 2, the care seat mounting base 3 can be removably mounted to the seat mounting portion 11 in the vehicle interior 10 by using a means such as a bolt. As well shown in FIG. 4, the nursing seat attachment base 3 has a sheet moving guide 4 and a pair of fixed rollers on the upper surface of a base block 30 that can be arranged on the floor 13 and has a rectangular block shape, for example. 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 front end portions of a pair of roller rails 40 are connected to each other via a crank-shaped connecting member 41, and the overall plan view shape thereof is a substantially U-shaped frame shape. It is a thing. Each roller rail 40 corresponds to an example of the "sliding rail" in the present invention, and the plurality of rollers 40b, which are its constituent members, correspond to an example of the "sliding member" in the present invention. The plurality of rollers 40b of each roller rail 40 are arranged in a row in the lateral width direction of the base portion 30, and the pair of roller rails 40 are arranged at intervals in the front-back direction of the base portion 30. ..

The sheet movement guide 4 can be reciprocally slid in the direction indicated by the arrow Nc. As a means for this, for example, a means for slidably fitting a projection 40c connected and fixed to one side of each roller rail 40 into a slide guide rail 49 having a substantially C-shaped cross section is adopted. As a result, as shown in FIGS. 2 and 3, when the care seat mounting base 3 is mounted on the floor 13 in the passenger compartment 10, the seat moving guide 4 is moved to the door opening of the vehicle 1. It can be set in a state of being projected to the outside of the vehicle through the portion 12. In such a set state, as will be described later, it is possible to carry the care sheet 5 into the vehicle compartment 10 from the wheelchair A by using the seat movement guide 4.

The connecting member 41 of the sheet movement 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 tip end portion of the seat movement guide 4 is arranged on the upper surface of the seat mounting portion 62 of the wheelchair A. At the same time, the connecting member 41 can be located between the engaging convex portion 62a on the upper surface of the sheet placing portion 62 and the pair of upward convex guide portions 67. With this setting, the sheet placing portion 62 and the sheet moving guide 4 can be positioned in the lateral width direction of the sheet placing portion 62. When the connecting member 41 is engaged with the engaging convex portion 62a, the sheet moving guide 4 is prevented from being accidentally detached from the sheet placing portion 62 in the direction of the arrow Ne. Further, the connecting member 41 is brought into contact with the upward convex guide portion 67 to prevent the sheet moving guide 4 from excessively advancing in the direction opposite to the arrow Ne with respect to the sheet placing portion 62. As a result, it is possible to prevent inadvertent misalignment between the seat movement guide 4 and the carriage 6 of the wheelchair A.

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 abuts on the inclined surfaces 69a. , A part for guiding the position of the sheet movement guide 4 to a predetermined appropriate position. The inclined surface portion 59 near the lower surface portion of the nursing care sheet 5 shown in FIG. 6 smoothly transfers the nursing care sheet 5 onto the sheet moving guide 4 from the sheet placing portion 62. It is a part for making it.

In FIG. 4, the pair of fixed roller rails 31 of the care sheet mounting base 3 receives the load when the care sheet 5 moves onto the care sheet mounting base 3 and also mounts the care sheet. 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 moving guide 4 are projected outward from the care sheet mounting base 3, and Although it is difficult to support the care sheet 5 that has advanced to the mounting base 3 by the sheet movement guide 4, the fixed roller rail 31 plays a role of supporting the care sheet 5 instead.

As shown in FIG. 4( b ), 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 form a pair. Between the upward convex guide portions 32. The pair of second downward convex guide portions 56b 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 portion 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, in the state where the care sheet 5 is arranged on the care sheet mounting base 3, the care sheet 5 is carelessly moved to the outside of the vehicle. A locking mechanism is provided to prevent the The movement prevention lock state of the care sheet 5 by this 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 it is not necessary to make the vehicle 1 a so-called nursing care specification, a normal vehicle seat 2 may be attached to the seat attachment portion 11 and installed in the vehicle compartment 10. On the other hand, when the vehicle 1 has a nursing care specification, the ordinary vehicle seat 2 is removed from the seat mounting portion 11, and then the care seat mounting base 3 is mounted on the seat mounting portion 11. According to such a setting state, the care sheet 5 of the wheelchair A can be carried into the vehicle interior 10 using the seat movement guide 4 and fixed on the care sheet mounting base 3. This operation is specifically as follows.

That is, as shown in FIG. 3, first, in a state in which the wheelchair A is moved to the side of the vehicle 1, the seat movement guide 4 is slid so as to project to the outside of the vehicle, and the tip end portion thereof is seated on the wheelchair A. Place it on 62. If the height of the sheet placing portion 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 placing portion 62. As shown in FIG. 3, an optical sensor 99 for detecting an appropriate portion of the wheelchair A is provided on the care seat mounting base 3 and the height of the seat mounting portion 62 is adjusted when the height is adjusted. It is also possible to adopt a means for detecting this by the optical sensor 99 and notifying it with a buzzer sound or the like when the height reaches an appropriate height.

When the front end portion of the sheet moving guide 4 is placed on the sheet placing portion 62, as described with reference to FIGS. 6 and 7, the connection member 41 is used to align the two, and It is possible to appropriately prevent the positional deviation, and it is possible to prevent the leading end portion of the sheet moving guide 4 from falling off from the sheet placing portion 62. After that, after releasing the locked state of the care sheet 5, the caregiver pushes the care sheet 5 by hand with the person sitting on the care sheet 5 of the wheelchair A and moves it onto the seat movement guide 4. After that, the seat moving guide 4 is slid on the car 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 backward to return 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 by using the connecting member 41, the strength thereof can be increased, and the plurality of rollers 40b are spaced at appropriate intervals. Since it is provided in two rows, it is possible to stably support and guide the care sheet 5. Therefore, the care sheet 5 and its occupants can be carried into the vehicle interior 10 in a stable state without causing significant rattling.

Contrary to the above, even when the care sheet 5 is carried out of the vehicle and returned to the dolly unit 6, the seat moving guide 4 is projected to the outside of the vehicle, and the tip end portion thereof is seated on the seat mounting portion 62 of the dolly unit 6. Put it on top. After that, after unlocking the locked state of the care sheet 5 with respect to the care sheet mounting base 3, the care sheet 5 is pushed toward the trolley portion 6 side. This makes it possible to appropriately move the care sheet 5 onto the sheet placing portion 62 by using the sheet movement guide 4. Also in this case, a person may remain seated on the care sheet 5.

When it is no longer necessary to make the vehicle 1 a so-called welfare specification, by removing the care seat mounting base 3 from the seat mounting portion 11, the normal vehicle seat 2 is remounted to the seat mounting portion 11. Is possible. As described above, according to the vehicle structure C of the present embodiment, the state in which the normal vehicle seat 2 is installed in the vehicle compartment 10 and the care seat 5 from the outside of the vehicle instead of the normal vehicle seat 2 are provided. It is possible to easily switch between a state in which the vehicle can be carried in and out. Therefore, flexibility and convenience can be excellent. Further, the care sheet 5 is moved manually, and since it is not necessary to incorporate a motor into the care sheet mounting base 3, for example, reduction in overall manufacturing cost and weight reduction are also suitable. It is possible to plan.

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

The sheet movement guide may be in the form of, for example, a plate in plan view, instead of the U-shaped frame in plan view. The connecting member of the sheet movement guide is not limited to a wire-shaped member or the like, and may be a plate-shaped member or other member.
The "sliding member" and "sliding rail" 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 bearing shape in another form such as a spherical shape, or is a member having a smaller surface friction coefficient than the frame supporting the sliding member. Therefore, it may be, for example, a corrugated plate that can smoothly slide the care sheet. 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 through the door opening on the side of the vehicle, but the present invention is not limited to this. For example, the vehicle may be carried in and out through the door opening (back door opening) at the rear of the vehicle. 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 for normal use does not necessarily have to be installed in a specific location inside the vehicle interior. It can also be attached to a specific location in the passenger compartment. In this case, in a car dealer, etc., the work for removing the nursing care seat mounting base, the work for mounting a normal vehicle seat, and the like may be performed as necessary. The car seat mounting base, or a regular vehicle seat, need not be carried by the vehicle user, and may be, for example, sold, rented, or stored by an automobile dealer.
