There are also wheelchairs without anchor bars. Therefore, there is a demand for a vehicle in which a wheelchair can be fixed to the rear floor regardless of the type of wheelchair.

One of the objects of the present invention is to provide a vehicle in which a wheelchair can be fixed to the rear floor regardless of the type of wheelchair.

A vehicle according to an aspect of the present invention is a vehicle that includes a rear floor on which a wheelchair is mounted, wherein a portion of a frame provided on the wheelchair abuts or engages to restrict forward movement of the wheelchair on the rear floor. and an anchor portion detachably supporting an anchor belt for restricting forward movement of the wheelchair on the rear floor.

According to the configuration of the present invention, various types of wheelchairs can be easily fixed. For example, when a wheelchair equipped with an anchor bar is mounted on a vehicle, a stopper portion is attached to the anchor portion. The forward movement of the wheelchair is prevented by the anchor bar coming into contact with or being engaged with the stopper. Therefore, in the above vehicle, the wheelchair provided with the anchor bar can be fixed to the rear floor. When a wheelchair without an anchor bar is mounted on a vehicle, an anchor belt is attached to the anchor portion. Anchor belts are wheelchair anchors that consist of a belt and a hook. The forward movement of the wheelchair is prevented by hooking the hook of the anchor belt on the frame of the wheelchair from the rear side of the wheelchair. Therefore, in the above vehicle, even a wheelchair without an anchor bar can be fixed to the rear floor.

Both frames 11 are provided with a seat 151, a back support 152, a leg support 153, a foot support 154, and a handle 155, as shown in FIG. Both frames 11 are also provided with arm supports (not shown). Illustration of the axle 131 of the rear wheel 13 and the spokes is omitted.

Each frame 11 has a front piece 11f, a rear piece 11r, an upper piece 11u, and a lower piece 11d, as shown in FIG. The front piece 11 f is provided on the front side of the wheelchair 10 . The front piece 11f extends vertically. The rear piece 11 r is provided on the rear side of the wheelchair 10 . The rear piece 11r extends vertically. The upper piece 11 u is provided on the upper side of the wheelchair 10 . The upper piece 11u extends in the front-rear direction. The lower piece 11 d is provided on the lower side of the wheelchair 10 . The lower piece 11d extends in the front-rear direction. The upper piece 11u is connected to the front piece 11f and the rear piece 11r. The lower piece 11d is connected to the front piece 11f and the rear piece 11r. A front wheel 12 is connected to the lower portion of the front piece 11f. The front wheels 12 are auxiliary wheels. An axle 131 of the rear wheel 13 is connected in the middle of the rear piece 11r. The rear wheels 13 are drive wheels.

Anchor bar 14 is fixed to frame 11 via bracket 14b. The anchor bar 14 of this example is provided inside the rear wheel 13 and below the axle 131 of the rear wheel 13 when the wheelchair 10 mounted on the rear floor 9 is viewed from the side. The inner side of the rear wheel 13 means the inner side of the outer peripheral edge of the rubber tire of the rear wheel 13 . Anchor bar 14 may be detachable from frame 11 of wheelchair 10 .

The wheelchair 10 mounted on the vehicle 1 of this example may be a wheelchair 10 without anchor bars, as shown in FIG. 5, which will be described later.

[Electric winch]
The electric winch 2 provided in the vehicle 1 of this example is a device that pulls the wheelchair 10 forward of the vehicle 1, as shown in FIG. In the vehicle 1 of this example, one electric winch 2 is provided on each of the left and right sides of the front side of the rear floor 9 . A known configuration can be used for the electric winch 2 . The electric winch 2 includes, for example, a winding device 21, a lock mechanism, a belt 22 and a hook 23. Illustration of the lock mechanism is omitted.

The winding device 21 winds up the belt 22 . Winding of the belt 22 by the winding device 21 can be operated by a remote controller (not shown). The locking mechanism prevents the belt 22 from being let out. A ratchet mechanism, for example, can be used as the locking mechanism. This lock mechanism can be released by the remote controller. Specifically, when the release operation is performed by the remote controller, the winding device 21 rotates once in the direction in which the belt 22 is wound up, thereby releasing the engagement between the pawl and the gear of the ratchet mechanism, and the pawl is released. away from the gears. Therefore, the belt 22 can be extended. The belt 22 is connected to the winding device 21 . A hook 23 is provided at the tip of the belt 22 . The hook 23 is hooked on the frame 11. - 特許庁Therefore, the electric winch 2 that pulls the wheelchair 10 forward of the vehicle 1 also serves to prevent the wheelchair 10 from moving backward.

[Stopper part]
The stopper portion 3 prevents the anchor bar 14 from advancing. By preventing the anchor bar 14 from advancing, the wheelchair 10 is prevented from advancing. The stopper portion 3 is provided on the rear floor 9 via a later-described slide mechanism 4 (FIG. 3). The stopper portion 3 may be provided so as to protrude above the rear floor 9 at all times, or may be provided on the rear floor 9 so as to be retractable.

The stopper portion 3 of this example includes a base portion 31 and a body portion 32, as shown in FIG. The base portion 31 of this example is detachably attached to the slider 41 . The base portion 31 is a member that supports the body portion 32 . The configuration for making the base portion 31 detachable from the slider 41 is not particularly limited. For example, there is a configuration in which the base 31 is screwed to the slider 41 . Alternatively, the base 31 may be detachably attached to the slider 41 by a tongue provided at the bottom of the base 31 and a lock mechanism provided on the slider 41 .

The body portion 32 of this example has a substantially inverted L shape when viewed from the side and a substantially U shape when viewed from above. The body portion 32 includes a pair of left and right vertical pieces 32A, a pair of left and right horizontal pieces 32B, and one cross piece 32C. In FIG. 3, only the left longitudinal piece 32A and transverse piece 32B of the vehicle 1 are visible. 32 A of vertical pieces are rod-shaped bodies extended upwards from the base 31. As shown in FIG. The horizontal piece 32B is a rod-shaped body extending rearward of the vehicle 1 from the upper end of the vertical piece 32A. A joint between the vertical piece 32A and the horizontal piece 32B is rounded. An inner angle portion between the vertical piece 32A and the horizontal piece 32B constitutes a stop portion 30 for stopping the anchor bar 14. As shown in FIG. 32 C of cross pieces are rod-shaped bodies which connect the rear ends of two horizontal pieces 32B and 32B arrange|positioned at the distant position of the vehicle width direction. The cross piece 32C reinforces the body portion 32 by connecting the left and right horizontal pieces 32B, 32B.

Here, the shape of the main body portion 32 is not particularly limited as long as it is configured so as to abut or engage with the anchor bar 14 . For example, a flap-type body portion 32 whose rotation angle is limited to 90° or less, and a hook-type body portion 32 configured to be rotatable can be used. Preferably, the hook-type body portion 32 has an engagement recess with which the anchor bar 14 engages. If the body portion 32 has an engaging recess, the electric winch 2 may be omitted. These arrangements comprise relatively complex mechanisms with pivots. On the other hand, since the main body portion 32 of this example has a simple structure that does not include a rotating shaft or the like, the vehicle 1 of this example is excellent in productivity in terms of the cost of the stopper portion 3 and ease of mounting work. .

[Slide mechanism]
The vehicle 1 of this example includes a slide mechanism 4 that changes the position of the stopper portion 3 in the vehicle front-rear direction. The slide mechanism 4 is not essential. In that case, the stopper portion 3 is fixed to the rear floor 9 so as not to move.

The slide mechanism 4 supports the stopper portion 3 so as to be slidable in the longitudinal direction of the vehicle 1 . The slide mechanism 4 is provided on the rear floor 9 . The slide mechanism 4 includes a slider 41 , a rail 42 , a wire 43 , a winding mechanism 44 , a lock mechanism 45 and an unlocking mechanism 46 . In FIG. 3, the drawing of the winding mechanism 44 and the lock mechanism 45 is simplified for convenience of explanation. Note that the slide mechanism 4 may have a belt instead of the wire 43 .

The slider 41 slides on the rail 42 . A base portion 31 of the stopper portion 3 is detachably connected to the slider 41 . The rail 42 is provided along the longitudinal direction of the vehicle 1 . A wire 43 connects the slider 41 and the winding mechanism 44 . The winding mechanism 44 winds the wire 43 . A known configuration can be used for the winding mechanism 44 . Although not shown, the winding mechanism 44 may have a configuration including a pulley and a winding spring, for example. The lock mechanism 45 prevents the wire 43 from being let out. Therefore, the lock mechanism 45 can prevent the slider 41 from advancing. Although not shown, for example, a ratchet mechanism can be used as the lock mechanism 45 . The unlocking mechanism 46 unlocks the locking mechanism 45 . This release enables the wire 43 to be paid out. The unlocking mechanism 46 unlocks the pawl of the ratchet mechanism from the gear, moving the pawl away from the gear. This unlocking mechanism 46 enables the slider 41 to move forward. Instead of the winding mechanism 44, a pull-back structure using spring tension may be employed.

[Anchor part]
The slider 41 of this example described above also serves as the anchor portion 5 . The anchor portion 5 is configured to detachably support the stopper portion 3 and the anchor belt 6 shown in FIG. 5 shows a state in which the stopper portion 3 of FIG. 4 is removed from the slider 41 and the anchor belt 6 is attached to the slider 41. As shown in FIG.

The anchor belt 6 includes a base 61 , a connecting belt 62 , a connecting fitting 63 , two belts 64 and two hooks 65 . The base 61 is detachably attached to the slider 41 . The configuration for making the base portion 61 detachable from the slider 41 is the same as the configuration for making the base portion 31 of the stopper portion 3 detachable from the slider 41 .

The connecting belt 62 connects the connecting fitting 63 to the base portion 61 . The connecting fitting 63 is a substantially triangular annular fitting. A connecting belt 62 is attached to one side of the connecting fitting 63 . A belt 64 is attached to each of the remaining two sides of the connecting fitting 63 . A hook 65 is attached to the tip of each belt 64 . One belt 64 may be sufficient. In that case, the belt 64 may be provided on the base 61 .
