SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wheelchair fixing device for a vehicle in which an occupant of a wheelchair can easily perform a fixing and releasing operation by himself / herself in view of the above-mentioned conventional problems.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention comprises a main body installed on a vehicle cabin floor with a width that fits between the left and right wheels of a wheelchair, and an operation unit connected to the main body. The main body has a pair of front and rear wheel stoppers projecting left and right and rotating around a horizontal axis and capable of standing up, and a middle part sandwiched between the pair of wheel stoppers, and a holder at an end. A slider capable of extending the holder to the left and right outwards is provided, and the wheel stopper and the slider are configured to be driven by operation of the operation unit, respectively. The movement in the front-rear direction is prevented, and the holder of the slider abuts the inside of the wheel to prevent the movement of the wheelchair in the left-right direction. Thereby, the wheel stopper and the slider are operated by the operation of the operation unit,
Since the movement of the wheelchair in the front-rear direction and the left-right direction is prevented, troublesome work is not required.

[0005] The pair of wheel stoppers may be constituted by rods having both ends bent in the shape of a crank, with straight portions at both ends protruding left and right outward. The slider includes a left slider that can extend to the left and a right slider that can extend to the right.Each has a slide body that is provided with a rollable roller and is guided by a slider case. It consists of an upper holder and a side holder, and is provided at the end of the slide body so as to be rotatable around a horizontal axis. When the side holder comes into contact with the inside of the wheel, the side holder rotates and the upper holder presses the rim of the wheel from above. It is preferable to configure as follows.
Thus, the side holders of both sliders abut against the inside of the wheel to regulate the left and right directions, and the upper holder presses the rim, so that the up and down dance of the wheelchair can be suppressed at the same time.

It is preferable that the holder is supported by a first frame fixed to the slide body, and is urged outward and upward by a first spring. When the holder comes into contact with the wheel, the upper holder is open upward, so that even if the size of the rim of the wheel varies, the rim can be pressed down without interference. The holder further includes a second frame, and the upper holder is rotatable around the vertical axis of the second frame, and is urged by a second spring in a direction parallel to the sliding direction of the slide body. By doing so, when it interferes with a spoke or the like, it turns around the vertical axis to avoid the spoke or the like.

A cable is connected to each of the pair of wheel stoppers, the left slider and the right slider, and an operating portion is provided with an operating lever. And the slider can be configured to be driven. In particular, the pair of wheel stoppers are connected by a single cable A wound around a first pulley,
Of the pulley according to the rotation of the operation lever,
The left slider and the right slider are connected by a single cable B looped over a second pulley, and the second pulley is stroked in accordance with the rotation of the operation lever, so that an equalizer function is obtained for each. Even if the position of the wheelchair with respect to the main body is roughly adjusted, all wheel stoppers and sliders surely abut against the wheel, and the wheelchair is securely fixed.

Further, the first pulley and the second pulley are wound around one common cable C, and the cable C
Is connected to the operation lever, so that both the wheel stopper and the slider can be operated only by operating one operation lever without providing an individual lever.

Next, the holder assembly will be described. FIG. 8 is a side view of the holder assembly, and FIG. 9 is a sectional view taken along the line YY in FIG. Referring to FIGS. 6, 8 and 9, holder assembly 50 includes slide body 4
5, a first frame 51 having two opposed vertical walls 52, 52, and a horizontal shaft 5 provided between the vertical walls 52, 52.
Two horizontal walls 5 rotatable about 3 and facing up and down
It has a second frame 54 having 5 and 55 and an upper holder 57 rotatable about a vertical axis 56 provided between the horizontal walls 55 and 55. A side holder 58 extending downward is provided on the lower side wall of the second frame 54.

The first frame 51 has an upper wall 59 connecting the two vertical walls 52. A first spring 60 is attached to the upper surface of the upper wall of the second frame 54, and the tip of the spring contacts the upper wall 59 of the first frame, and the second frame 5 in FIG.
4 is urged to rotate clockwise. As shown in FIG. 8, an upper holder 57 is
A second spring 62 that holds and urges in a direction parallel to the vertical wall of the frame body 51, and thus parallel to the sliding direction of the slide body, is attached.

The right slider 32 has the same structure as the left slider 31 except that the holder assembly 50 is fixed to the right end and the second frame 54 is urged to rotate counterclockwise. I have. When not in use, the left slider 31
In order to return the right slider 32 to the initial position shown in FIG. 3, a return spring (not shown) is provided between the base 11 and the slider case 40, respectively.

In using the wheelchair fixing device configured as described above, the wheelchair 1 raised on the floor 6 is advanced onto the main body 10 while the occupant is on the wheelchair. When the wheel shaft 5 is located at the center of the main body 10, that is, on the slider 30, the operation unit 9 provided on the side wall 7 in the vehicle interior
Pull the 0 operation lever 92.

Thus, the wheel stoppers 20, 25
Rises and abuts the wheels 3 and 4 to prevent the wheelchair 1 from moving back and forth. At the same time, the holder assembly of the slider 30 extends in the left-right direction, and the side holder 58 abuts the side surfaces of the wheels 3 and 4 from inside, thereby preventing the wheelchair 1 from moving in the left-right direction. At the same time, the upper holder 57 presses the rims of the wheels 3, 4 from above. In this way, when the wheelchair 1 is prevented from moving in the left-right direction and the holder, which suppresses the vertical dance, comes into contact with the wheel, the size of the rim of the wheel varies because the upper holder is opened upward. Even without interference, it fits and holds down the rim.

The above operations of the wheel stopper, the slider and the holder are performed in cooperation with each other by the rotation of the operation lever 92, but they will be described separately for easy understanding.
First, the operation of the wheel stoppers 20, 25 will be described with reference to FIG. During this time, the position of the pulley A does not change and the slider 30 does not operate. When the inner cable 81 of the first cable 80 is pulled by pulling the operating lever 92 of the operating unit 90, the inner cable 81 extends from the outer cable of the bracket 71, is returned by the pulley C via the pulleys A and B, and is turned back by the terminal 82. The length of the inner cable 81 up to the fixed end is reduced. As a result, the pulley C strokes along the slit 75 in the right direction in FIG.

Thus, the pulley C (upper pulley C
1), and the second and third cables 85, 8
7, the lever 23 of each wheel stopper 20, 25,
The inner cable 86 connected to 28 is pulled. In this way, as shown in FIG. 11A, the wheel stoppers 20, 25 whose linear portions 21, 26 were on the lower surface of the base 11 (floor 6) in the initial state are rotated as shown in FIG. Then, it comes up and contacts the wheel 3 (4). Also, in the case of the wheel 3 'having a different diameter depending on the wheelchair, the wheel stoppers 20 and 25 are securely attached to the wheel only by a different rotation angle and therefore an operation stroke of the operation lever 92 as shown in FIG. Abut

It is preferable that the wheel shaft 5 of the wheelchair 1 be located at the center of the main body 10, that is, on the slider 30, as described above. In this case, FIG.
As shown in FIG. 7, the front and rear wheel stoppers 20 and 25 stand substantially symmetrically at the same height. However, since the inner cable 86 connected to the levers 23 and 28 of each wheel stopper is pulled by the pulley C, the wheel shaft 5 does not need to be accurately positioned at the center of the main body 10.
That is, since the rotatable pulley C functions as an equalizer, even when the wheel axis position is offset by D from the center Z of the main body 10 as shown in FIG. When the operating lever is further pulled after contacting the wheel, the other wheel stopper also contacts the wheel, so that the movement of the wheelchair in both the front and rear directions is reliably prevented.

Further, even when the wheelchair 1 is positioned on the main body 10 in a slightly horizontal state, one of the right and left sides of the linear portions 21 and 26 of the wheel stoppers 20 and 25 abuts on the wheel. After further operation lever 92
, The direction of the wheelchair 1 is corrected,
Both left and right sides of the wheels 1 and 26 are in contact with the wheel.

Next, the operation of the slider 30 will be described with reference to FIG. During this time, the position of the pulley C does not change, and the wheel stoppers 20 and 25 do not operate. By pulling the operation lever 92 of the operation unit 90, the first
When the inner cable 81 of the cable 80 is pulled, it extends from the outer cable of the bracket 71 to pulley A,
The length of the inner cable 81 is shortened to the end fixed by the terminal 82 by being turned back by the pulley C via the pulley B. As a result, the pulley A moves along the slit 73 as shown in FIG.
3. Stroke rightward.

As a result, the cable 89 laid over the pulley A2 below the pulley A on the lower surface side of the sub base 70
Is drawn. This cable 89, on the other hand,
Connected to the arm 37 of the left slider 31 via E and F,
On the other hand, the arm 38 of the right slider 32 passes through the pulleys G and H.
, Both sliders move and extend outward respectively.

As a result, the side holder 58 of the holder assembly 50 comes into contact with the side surfaces of the wheels 3 and 4. As a result, the first frame 51 of the holder assembly is rotated against the urging force of the first spring 60, and the upper holder 57 is moved from above to the wheel 3, as shown in FIG. Hold down the rim of 4. FIG. 14 shows the pulleys F and H and the cable 89 in an overlapping manner. In this way, the movement of the wheelchair 1 in the left-right direction is prevented, and the vertical dance is also suppressed.

Further, like the wheel stopper, the cable 89 is pulled by the rotatable pulley A, so that the pulley A functions as an equalizer, and the gaps between the main body 10 and the left and right wheels 3, 4 are completely equal. Even if not, by further pulling the operating lever 92 after one of the holder assemblies abuts on the wheel, the other holder assembly also abuts on the wheel, and the movement of the wheelchair in both the left and right directions is reliably prevented.

The upper holder 57 of the slider is usually parallel to the sliding direction of the slide body 45 by the second spring 62. However, when the upper holder 57 interferes with spokes when pressing the rims of the wheels 3, 4, FIG. As shown in (5), it turns around the vertical axis 56 to avoid the spokes and the like. Although the operations of the wheel stopper and the slider have been described separately and independently, as described above, the two operate in cooperation with each other or sequentially from the one with the smaller actual resistance load.

The present embodiment is constructed as described above, and the wheel stoppers 20, 2 extending from the front to the
5 and a left and right slider 31, 32 extending right and left with a holder assembly 50 at the end at the center.
Wheelchair 1 positioned so as to straddle the main body 10
By operating the operation lever by connecting the operation lever 92 disposed on the side wall 7 of the passenger compartment and the main body 10 with a cable, and operating the operation lever, the wheel stoppers 20 and 25 rise and come into contact with the wheel from the front and rear, and the slider 30 is moved.
The holder assembly contacts the wheel from above and from the inside, so that the occupant of the wheelchair can perform the fixing and releasing operations by a simple operation of merely moving the operation lever. For this reason, the caregiver does not need to perform troublesome work in the narrow cabin, and the time required for fixing is significantly reduced.

Since the drive mechanism of the wheel stopper and the slider in the main body 10 is provided with an equalizer function by using a pulley, the wheelchair can be securely fixed only by roughly positioning the main body therebetween. This has the effect.

In the above embodiment, the cables are used to connect the operation elements, but the present invention is not limited to this. Although a cable is preferable for routing between the operation unit and the main body, the same operation can be obtained by replacing it with a chain in the main body.
In that case, a gear sprocket may be used instead of the pulley. Therefore, in the present invention, the cable includes the chain, and the pulley includes the gear sprocket. In addition, in the embodiment, the operation unit including the operation lever is provided on the side wall in the passenger compartment. However, the operation unit is not limited to the side wall. A lever can also be provided.

[0041]

As described above, the present invention comprises a pair of front and rear wheel stoppers which are protruded to the left and right and are rotatable and standable, and holders at the end portions, which are provided on the main body installed on the floor of the passenger compartment. A slider that can extend outward is provided, and the wheel stopper and the slider are driven by operation of the operation unit connected to the main body. Movement of the wheelchair, and the slider holder abuts the inside of the wheel to prevent the wheelchair from moving in the left-right direction. This has the effect that the work of the caregiver in the narrow cabin is eliminated and the time required for fixing is significantly reduced.

Further, the holder is composed of an upper holder rotatable around a horizontal axis and a side holder, and the side holder is rotated by contacting the inside of the wheel so that the upper holder presses the rim of the wheel from above. By doing so, the up and down dance of the wheelchair can be suppressed at the same time. Further, the above holder is supported by the first frame fixed to the slide body and is urged outwardly upward by the first spring, so that even if the size of the rim of the wheel fluctuates, interference occurs. The rim can be pressed down to fit without the need.

The holder further comprises a second frame,
The upper holder is movable about the vertical axis of the second frame, and is urged by the second spring in a direction parallel to the sliding direction of the slide body, thereby causing interference with spokes and the like. In some cases, there is an advantage that the rim can be reliably pressed while rotating around the vertical axis to avoid the spokes and the like.

The pair of wheel stoppers are connected by a single cable wound around a first pulley, and the right and left sliders are connected by a single cable wound around a second pulley. By making each pulley stroke according to the rotation of the operation lever, an equalizer function is obtained,
Even if the position of the wheelchair with respect to the main body is roughly adjusted, the wheelchair is securely fixed. Further, the first pulley and the second pulley
By pulling the pulley around with one common cable and connecting the cable to the operation lever, both the wheel stopper and the slider can be operated by operating only one operation lever.
