Description

Description: TECHNICAL FIELD The present invention relates to a method of moving a person with a lower limb on the road and a connector used for carrying out the method.

[Conventional technology and its problems]

Conventionally, the following methods have been widely used as a method for a person with a lower limb disability to go outdoors and move on the road. Each has advantages and disadvantages.

a How to use a wheelchair.

This method is a method in which a person with a lower limb disability in a wheelchair can move by turning the hand rim by hand, and has the advantage of being able to move freely by himself, but since the wheelchair has no power, it has a very strong arm strength. Unless you are a person, you cannot move on a slope alone, and you cannot move a long distance on a flat road.

b How to use an electric wheelchair.

This method is a method in which a person with a lower limb disorder himself moves on the road by manipulating an electric wheelchair equipped with a battery and a motor using it as a power source, and even a person with weak arm strength can easily drive, unlike an ordinary wheelchair, There is an advantage that you can move on the road,
Since the energy capacity of the battery is low, it cannot be moved over long distances.

c How to use a wheelchair-loaded vehicle.

In this method, with the help of a caregiver, a person with a disability in the lower limbs rides in a car with an elevator attached to the car and moves on the road while sitting on the wheelchair in the car. This method has the advantage that it can be moved over a long distance without the physical loss of persons with lower limb disabilities, but it requires expensive wheelchair-carrying vehicles, caregivers, and drivers when moving. When moving on the road with the help of a caregiver, there are some feelings that the person with a lower limb disability feels hesitant to refrain from the caregiver, and if the care fee or the fee for using a wheelchair-carrying vehicle is expensive. Some people can't pay.

As described above, in the conventional method, the person with a lower limb disability cannot freely move on the road as much as he or she is satisfied.

Recently, in order to be able to move freely over long distances without the assistance of a caregiver, a wheelchair on the road can be automatically folded and loaded onto the roof of a passenger with a single button operation on the driver's seat of a passenger car. Also, a wheelchair storage device for a passenger car, which can drop a wheelchair loaded on a roof onto the road, has been introduced. However, most of the disabled persons cannot use the wheelchair storage device and the passengers who have been modified for the disabled persons because they are very expensive and the maintenance cost is high. Many people with lower limb disabilities have a strong desire to move freely on the road at a low cost, without hesitation to anyone over long distances, but it is unfortunate that this wish has not come true. That's a thing.

INDUSTRIAL APPLICABILITY The road moving method of the present invention and the connecting tool used for carrying out the method were devised for the purpose of freely moving on the road for a long distance at a low cost for a person with a disability in the lower limbs and without any trouble of obtaining the same. It is a thing.

[Means for solving problems]

The road moving method of the present invention and the connecting tool used for carrying out the method are to move on the road by using an ordinary wheelchair that is used daily by a person with a disability in the lower limbs, but in this case, like the conventional method. Instead of just using a wheelchair to move on the road, we also use special couplings and scooters that are often used in the city. That is, when a person with a leg injury in a wheelchair moves on the road, after the person with a leg impairment positions the wheelchair in parallel with the scooter,
Each fixing means of a connector having a fixing means for a scooter at one end of the main body or a vicinity thereof and a fixing means for a wheelchair at the other end or a vicinity thereof is fixed to the scooter and the wheelchair. Next, the person with a lower limb disability is configured to transfer from the wheelchair to the scooter by himself and drive the scooter himself.

[Action]

In the present invention, all that is required for traveling on the road is a wheelchair that has been conventionally used by persons with lower limbs and a connector and a scooter that can be provided at low cost. Then, the movement of the road is done by the person with the lower limb by himself using a scooter.

〔Example〕

An embodiment of a method for moving a person with a lower limb on the road to achieve the object of the present invention by using the connecting tool (1), the scooter (2), and the wheelchair (3) will be described below with reference to the drawings.

FIG. 8 is a perspective view of the connector (1). In FIG.
The main body (1-1) has a scooter fixing means (1-2) at one end
At the other end, there is a means (1-3) for fixing to a wheelchair.
FIG. 9 shows a sectional view taken along the line AA of FIG. Vertical plate (1-2-1),
The upper plate (1-2-2) and the lower plate (1-2-3) are a pair, Forming a mold. In the center of the outer surface of the vertical plate (1-2-1), the main body (1-
1) is fixed at right angles. A female screw (1-2-4) is provided at the center of the upper plate (1-2-2). The T-bolt (1-2-5) is screwed into the female screw (1-2-4). The tip of the T-bolt (1-2-5) is rotatably engaged with the central portion of the pressing plate (1-2-6). A slight gap (1-2-7) is provided between the holding plate (1-2-6) and the vertical plate (1-2-1). When the T bolt (1-2-5) is tightened, the step (2-2) is firmly clamped from the top and bottom with the upper surface of the lower plate (1-2-3) and the lower surface of the pressing plate (1-2-6). I am able to do it.

FIG. 10 is an enlarged view of the fixing means (1-3) to the wheelchair.
The fixing means (1-3) to the wheelchair is composed of block A (1-3-1) block B (1-3-2) butterfly bolt (1-3-3). The block A (1-3-1) is provided with a semicircular groove (1-3-4) in the center and two female screws (1-3-5) on both sides thereof. The main body (1-1) is fixed to the opposite side of the groove (1-3-4). Block B (1-3-
In 2), there is a semicircular groove (1-3-6) in the center and 2 on each side.
There are holes (1-3-7). The butterfly bolt (1-3-3) passes through the hole (1-3-7) and can be screwed into the female screw (1-3-5). When the right front pipe (3-2) is between the groove (1-3-4) and the groove (1-3-6), insert two butterfly bolts (1-3-3) into the holes (1-3- 7) Female thread through
When screwed into (1-3-5), the right front pipe (3-2) can be firmly clamped.

The connector 1 having such a structure can be manufactured by using metal, resin, or a combination thereof, but it can be manufactured at a very low cost because it has a simple structure regardless of the material.

In order for a person with a leg impairment in a wheelchair (3) to move on the road according to the method of the present invention, the person with a leg impairment primarily uses the normal wheelchair driving method, that is, turning the handle rim (3-1) by hand. The wheelchair (3) is brought close to the scooter (2) and positioned in parallel by the driving method. Fig. 2 shows the figure after it has been placed in parallel. Implementation of the secondary and subsequent operations is possible by completing the primary operation. Secondly, the scooter with the two fastening means of the connecting tool (1) on the wheelchair (3)
It is fixed to (2) and wheelchair (3), but the detailed procedure is as follows.

Step 1, Insert the step (2-2) of the scooter (2) between the upper surface of the lower plate (1-2-3) and the lower surface of the pressing plate (1-2-6), and insert the vertical plate (1-2-1 )
Push in the connector (1) until step (2-2) hits. When the step (2-2) hits the vertical plate (1-2-1), tighten the T bolt (1-2-5) with the other hand while keeping the touched state with one hand.

Thus, the fixing means (1-2) for fixing the scooter to the scooter (2) is completed. This figure is shown in FIG. [In FIG. 3, the wheelchair (3) located on the left side and the person with a lower limb are omitted in order to clearly show the fixing state of the scooter (2) and the connecting tool (1). ] At this point, the scooter (2) is supported by the side stand (2-1) and stands at a slight angle to the road surface.

Step 2, first remove the block B (1-3-2) and the two wing bolts (1-3-3) from the block A (1-3-1). Then the scooter (2) standing diagonally becomes vertical and the right front pipe
Block A (1-3) with your right hand so that (3-2) enters the groove (1-3-4)
Lift up -1) and pull it toward the right front pipe (3-2). When the right front pipe (3-2) enters the groove (1-3-4), put your right thumb on the right front pipe (3-2) so that you can keep that state, and at the same time, use the other four fingers to move the subject (1 -1) Hold. With the right hand keeping this state, the left hand is in the position where block B (1-3-2) is paired with block A (1-3-1) and surrounds the right front pipe (3-2). After positioning (1-3-2), insert two bolts (1-3-3) through holes (1-3-7)
Tighten it firmly in (1-3-5).

Now, the two fixing means have been fixed to the scooter (2) and the wheelchair (3). Connecting scooter (1) and wheelchair (3) (1)
FIG. 4 shows the state of being connected by. [In this figure, persons with lower limb disabilities are omitted to clearly show the connected state. In this state, the scooter (2) is maintained in a state perpendicular to the road surface, and the side stand (2-1) has its tip slightly floated from the road surface. At this point, it is preferable to raise the side stand (2-1) for the sake of safety while traveling on the road. In the case of the present invention, the side stand (2-1) is raised by hand while sitting on the wheelchair (3), instead of being raised by a foot like a normal person.

Thirdly, persons with lower limb disabilities are required to transfer from the seat (3-3) of the wheelchair (3) to the seat (2-3) of the scooter (2) by themselves and take a driving posture.

By the way, consider the case where a person with a leg disability sitting in a wheelchair indoors tries to transfer to a bed. The bets are wide,
It is stable and flat. The floor is flat and not uneven. Wheelchairs are always stable on the floor. In this way, there are no inconvenient conditions when trying to change to a bet indoors. Only good conditions are in place. Nevertheless, most people with lower limb disabilities generally call their caregivers without being transferred by themselves, and are held by the caregivers to be transferred. At first glance, when trying to switch from a wheelchair seat to a scooter seat on the street, it is similar to when you move to a bed indoors, but when you compare the environmental conditions for the transfer in detail, it is significantly different. That is, the seat of the scooter has a small area unlike the bed and is not flat. Moreover, unlike a bet, a scooter tilts in various directions, fluctuates, or, in the worst case, falls when the load position changes. Unlike the floor, the road is not always flat. There are slopes and irregularities. Wheelchairs are not always stable. Both the scooter and the wheelchair are unstable, so there is a sufficient risk of falling from the scooter to the road surface while transferring if you do poorly. There are many inconvenient environmental conditions when trying to transfer to a scooter on the road. Therefore, no matter how much you need to transfer from a wheelchair to a scooter, there is no way that a person with a lower limb disability who does not even try to transfer himself to a bed indoors should never transfer to a scooter on the street. Always seek help from a caregiver if you do not know how to transfer safely.

Even if there are many such inconvenient conditions, according to the present invention, the user can change on his own according to the procedure for safely changing. The procedure is as follows.

Step 1, left elbow rest with left hand while sitting in wheelchair (3)
Grip the center of (3-4) and the upper part of the right arm pipe (3-5) with your right hand. Next, lift your body with both arms, then twist your upper body to the left and sit on the right elbow pad (3-6). Figure 5 shows the result of step 1.

Step 2, right hand release the right arm pipe (3-5) and seat (2-3)
Place it on the front part and let the left hand release the left elbow pad (3-4) and the right hand grip (3-7)
Grab Then, while keeping your upper body from bending backward, shift your hips backwards and sit diagonally on the seat (2-3).
Figure 6 shows the figure after step 2.

Step 3, Grasp the right handle (2-4) for the right hand and the right elbow pad (3-6) for the left hand. While keeping the upper body stable with both arms, move both feet to step (2-2). If the degree of lower limb disorder is severe,
If you cannot move your toes only with the power of your lower limbs, hold your right elbow pad (3-6) firmly with your left hand and secure your upper body while lifting your legs one by one with your right hand. Step ahead (2
-You can move to 2). Figure 7 shows the end of procedure 3.

Finally, hold the left and right handles (2-4) (2-5) with both hands. Now you have transferred to the seat (2-3), have taken the driving posture, and are ready to drive the scooter (2). This figure is shown in FIG.

During the above procedure, a person with a lower limb disability should use the right elbow pad of the wheelchair (3).
(3-6), such as sitting on a peculiar place, or taking a peculiar posture such as shifting the hip while not bending the upper body backward, falls on the road surface during the transfer or scooter This is to prevent (2) from falling. In this way, the center of gravity of the body can be adjusted to a wheelchair (3) or scooter.
You can ride over the right elbow pad (3-6) without going outside of (2) and transfer from the low seat (3-3) to the high seat (2-3). After taking the driving posture, there is no danger of falling or falling to the road surface.

Fourthly, persons with lower limbs drive the scooter (2) by themselves to move on the road.

By the way, in order to drive a scooter, operations such as starting the engine, accelerating, applying a brake, giving a direction instruction, sounding an alarm, and turning on a light are necessary. Unlike most automobiles, most scooters on the market have all the equipment needed for driving centrally located at or near the steering wheel. Specifically, the engine is started by using the ignition key and the push button switch on the right side of the steering wheel, the accelerator is on the right hand accelerator, and the brake is on the front wheel on the right hand lever and the rear wheel on the left hand lever. Has a structure that can be operated with a switch attached to the handle. Therefore, it should have been possible for people with lower limb disabilities to drive scooters by simply operating their hands, but that was not possible. Because there are 1 driving operations that cannot be done by persons with lower limbs
There was only one. That is to support the scooter by dropping it on the road surface so that the scooter does not fall down while the vehicle is waiting for traffic signals. Because I couldn't do this, people with lower limb disabilities couldn't drive scooters, no matter how concentrated all the devices were on the steering wheel.

However, according to the present invention, since the wheelchair (3) and the scooter (2) are connected by the connecting tool (1), a mutual support action always works between them, and it is prevented from falling even when the vehicle is stopped.
Therefore, according to the present invention, a person with a lower limb disorder can scooter by himself.
You can freely drive on the street by driving (2).
You can even enter narrow roads where cars cannot enter. Moreover, the scooter (2) and the connecting tool (1) are much cheaper than an electric wheelchair as compared with an automobile, and can be moved over a long distance like an automobile. The fuel cost of the scooter (2) is about one fifth of the car.

[Other embodiment of connecting device]

Another embodiment of the connector is shown in FIGS. 11 to 12. First
Similar to the previous embodiment, the connecting tool (11) of FIG. 1 has a means (11-2) for fixing to a scooter at one end and a portion near the main body (11-1) and a means for fixing to a wheelchair (11-) at the other end. Have 3). Subject (11-1)
