Description

  TECHNICAL FIELD The present invention relates to a wheelchair wheel fixing device and a wheel fixing method for fixing wheelchair wheels to a vehicle floor.

  In recent years, wheelchair fixing devices for fixing a wheelchair to the floor of a vehicle such as a bus or ship have been developed. This type of wheelchair fixing device includes a retractor in which a wheelchair side hook that engages a wheelchair frame is attached to the tip of a belt, and the retractor is attached to and detached from a rail provided on the floor of a vehicle. (For example, refer to Patent Document 1).

  Since the wheelchair frame is fixed to the floor of the vehicle, the wheelchair fixing device can fix the wheelchair so that it does not move even when the vehicle suddenly stops or turns suddenly. However, since the connection between the frame and the floor is not visible to the wheelchair occupant, the opinion that the wheelchair wheel is fixed is psychologically safe, and the wheelchair wheel is more secure. Since there is an opinion that the movement of the wheelchair can be prevented, a wheel fixing device for fixing the wheel of the wheelchair to the floor of the vehicle has also been developed (see, for example, Patent Document 2).

  The wheel fixing device includes a wheel cover that covers an outer peripheral surface of an upper half of a wheel of a wheelchair, a front end cable that has one end connected to the front end of the wheel cover and the other end extending below the floor of the vehicle, and one end Is connected to the rear end of the wheel cover and the other end extends below the floor of the vehicle, and a motor is provided below the floor and winds the front end and rear end cables with a drum. The motor is driven after the wheel cover is put on the wheel of the wheelchair, and the wheel is pressed against the floor surface and fixed.

  However, since the front end side and rear end side cables are installed at predetermined positions on the floor surface, the wheel fixing device cannot change the position at which the wheelchair is fixed in the vehicle. In addition, since it is necessary to provide a motor under the floor surface, there is a space limitation for providing the motor, and the cost of remodeling the vehicle increases as much as the floor surface is peeled off once. Further, in order to securely fix the wheel, the wheel cover needs to be formed so as to extend along the upper half of the outer peripheral surface of the wheel, and the volume when accommodated when not in use is increased.

  The present invention has been made in view of such circumstances, and can arbitrarily change the position where the wheelchair is fixed in the vehicle, can reduce the cost of remodeling the vehicle, and can reduce the volume when accommodated. An object of the present invention is to provide a wheel fixing device and a wheel fixing method for a wheelchair that can be made small.

In order to solve the above problems, the present invention employs the following means.
A wheelchair wheel fixing device according to a first aspect of the present invention includes a retractor that is attached to and detached from an arbitrary position of a rail provided on a floor surface of a vehicle, and is fixed to a tip of a retractor belt of the retractor. A tip fixing anchor that is attached and detached at an arbitrary position, a fixing belt having one end and the other end connected to the retractor side of the retractor belt relative to the tip fixing anchor, and between the one end and the other end of the fixing belt A connecting belt for connecting the retractor belt between the one end and the other end, and the fixing belt when the retractor belt, the fixing belt, and the connecting belt are put on the outer peripheral surface of a wheel of a wheelchair. The retractor belt disposed in the vicinity of the one end and the other end of the wheel is configured to contact the outer peripheral surface of the upper half of the wheel.

  According to this aspect, the retractor and the tip fixing anchor can be attached to any position of the rail, and the position where the wheelchair is fixed can be freely changed within the range where the rail is provided. Here, when the retractor belt arranged in the vicinity of one end and the other end of the fixed belt is in contact with the outer peripheral surface of the upper half of the wheel and the retractor belt is wound by the retractor, the retractor belt comes into contact with two places on the outer peripheral surface of the wheel. Power is intensively applied. Therefore, the retractor belt bites into the outer peripheral surface of the wheel at the two wheel pressing positions, and the retractor belt and the wheel can be reliably fixed so as not to move relative to each other even when operated manually.

  Moreover, since the wheelchair wheel can be fixed simply by providing a rail on the floor of the vehicle, the cost of remodeling the vehicle can be reduced. Furthermore, since the fixed belt and the connecting belt are connected to the retractor belt, the volume when housed when not in use can be reduced.

  The wheel fixing device for a wheelchair according to a second aspect of the present invention is attached to the retractor belt so as to be movable in the longitudinal direction of the retractor belt between the connecting portion of the retractor belt and the fixing belt, and the retractor. An intermediate anchor is further attached to and detached from the rail between the retractor and the tip anchor.

  According to this aspect, a force to the rail side is applied to the retractor belt by the tip fixing anchor and the intermediate fixing anchor, and the retractor belt is compared with the case of using the retractor and the tip fixing anchor without providing the intermediate fixing anchor. The distance between the two rail-side force application positions that apply a force to the rail is reduced. For this reason, when the distance between the two rail side force acting positions is larger than the distance between the two wheel pressing positions, the downward force applied to the retractor belt can be further increased. In addition, when the distance between the two rail side force acting positions is smaller than the distance between the two wheel pressing positions, a force in the tensile direction is easily applied to the retractor belt when the wheels are about to move in the front-rear direction. The amount of movement in the direction can be further reduced.

The wheelchair wheel fixing device according to the third aspect of the present invention further includes a length adjusting means for adjusting the length of the fixing belt.
According to this aspect, the length of the fixing belt is changed in accordance with the size of the wheel, and thereby the distance between the two wheel pressing positions can be adjusted, so that the wheel can be reliably fixed regardless of the size.

The wheelchair wheel fixing device according to the fourth aspect of the present invention further includes connection belt adjusting means for adjusting the length of the connection belt.
According to this aspect, since the length of the connection belt can be changed according to the size of the wheel, wheels of various sizes can be reliably fixed.

  In the wheel fixing device for a wheelchair according to the fifth aspect of the present invention, the fixing belt is formed using a belt-shaped member, and the adjusting means is a first connecting portion provided on one end side of the belt-shaped member; And at least a second connecting part that is detachably connected to the first connecting part, the one end of the fixed belt being the inner side of the retractor belt. The belt is configured to be connected to the retractor belt by folding one end of the belt-like member so as to pass through and connecting the first connecting portion to the second connecting portion.

Further, the second connecting portion is configured to be capable of adjusting a position where the first connecting portion is connected in the length direction of the belt-like member.
For this reason, when the wheelchair is fixed near the wall of the vehicle or the like, the work space for adjusting the fixing belt placed on the wheel may be reduced, but the length of connecting the first connecting portion to the second connecting portion is long. By adjusting the position in the vertical direction, the length of the fixed belt can be adjusted, so that the length of the fixed belt can be easily adjusted according to the size of the wheel.

In the wheel fixing device for a wheelchair according to the sixth aspect of the present invention, the second connecting portion has connecting members provided at a plurality of locations at intervals in the length direction of the belt-like member.
According to this aspect, by arranging each connecting member at a position in the length direction corresponding to a predetermined wheel size, the fixing belt can be adjusted more easily according to the wheel size.

In the wheel fixing device for a wheelchair according to the seventh aspect of the present invention, the fixing belt has a color different from that of the retractor belt.
According to this aspect, the attachment can be performed smoothly even when the user is not used to the attachment work.

  A wheel fixing method for a wheelchair according to an eighth aspect of the present invention is a wheel fixing method for fixing a wheel of a wheelchair with the wheel fixing device, the step of attaching the retractor to an arbitrary position of the rail, and the retractor A step of covering the outer peripheral surface of the wheel of the wheelchair with the belt, the fixing belt and the connection belt, and the distance between the retractor and the tip fixing anchor is shorter than the distance between the one end and the other end of the fixing belt And attaching the tip anchoring anchor to the rail.

  According to this aspect, the position for fixing the wheelchair can be freely changed within the range in which the rail is provided. In addition, the retractor belt disposed in the vicinity of one end and the other end of the fixed belt is in contact with the outer peripheral surface of the upper half of the wheel, and force is applied intensively at two locations on the outer peripheral surface of the wheel where the retractor belt contacts. The retractor belt bites into the outer peripheral surface of the wheel at the wheel pressing position at the location, and even with a retractor operated manually, the retractor belt and the wheel can be reliably fixed so as not to move relatively.

  Moreover, since the wheelchair wheel can be fixed simply by providing a rail on the floor of the vehicle, the cost of remodeling the vehicle can be reduced. Furthermore, since the distance between the retractor and the tip fixing anchor, that is, the distance between the two rail side force acting positions that apply the force to the retractor belt to the rail side is smaller than the distance between one end and the other end of the fixed belt, When moving in the front-rear direction, a force in the tensile direction is applied to the retractor belt, and the amount of movement of the wheel in the front-rear direction can be further reduced.

  A wheel fixing method for a wheelchair according to a ninth aspect of the present invention is a wheel fixing method for fixing a wheel of a wheelchair with the wheel fixing device, the step of attaching the retractor to an arbitrary position of the rail, and the retractor A step of covering the outer peripheral surface of a wheel of a wheelchair with a belt, the fixing belt, and the connection belt; a step of attaching the tip fixing anchor to the rail; and a distance between the one end and the other end of the fixing belt. Attaching the intermediate fixed anchor to the rail so that the distance between the fixed anchor and the intermediate fixed anchor is shortened.

  According to this aspect, the position for fixing the wheelchair can be freely changed within the range in which the rail is provided. In addition, the retractor belt disposed in the vicinity of one end and the other end of the fixed belt is in contact with the outer peripheral surface of the upper half of the wheel, and force is applied intensively at two locations on the outer peripheral surface of the wheel where the retractor belt contacts. The retractor belt bites into the outer peripheral surface of the wheel at the wheel pressing position at the location, and even with a retractor operated manually, the retractor belt and the wheel can be reliably fixed so as not to move relatively.

  Moreover, since the wheelchair wheel can be fixed simply by providing a rail on the floor of the vehicle, the cost of remodeling the vehicle can be reduced. Furthermore, since the distance between the tip fixed anchor and the intermediate fixed anchor, that is, the distance between the two rail side force acting positions that apply the force to the rail to the retractor belt is smaller than the distance between one end and the other end of the fixed belt, When the wheel tries to move in the front-rear direction, a force in the pulling direction is applied to the retractor belt, and the amount of movement of the wheel in the front-rear direction can be further reduced.

  The present invention can arbitrarily change the position where the wheelchair is fixed in the vehicle, can reduce the cost of remodeling the vehicle, and can also reduce the volume when accommodated.

  This wheel fixing device is used to fix the wheel of a wheelchair on the floor of a vehicle such as a bus or a ship. In this embodiment, as shown in FIGS. 4 and 5, the pair of rails 1 are fixed to the floor so as to be parallel to each other, and the distance between the pair of rails 1 is the width of the position of the wheel 110 of the wheelchair 100. A little bigger than.

  When fixing the wheel 110 of the wheelchair 100 to this floor surface, first, the wheelchair 100 is arrange | positioned between a pair of rails 1, and each wheel 110 is arrange | positioned in the vicinity of the rail 1 so that it may become parallel to the rail 1 ( Step 1). Thus, since it is sufficient to arrange the wheelchair 100 along the rail 1, the arrangement of the wheelchair 100 is easy. Subsequently, the retractor 10 is attached to an arbitrary position in the length direction of the rail 1 (step 2), and the retractor belt 11 is unwound by operating the release lever 14 of the retractor 10 as shown in FIG. Then, the fixing belt 30 and the connection belt 40 are put on the outer peripheral surface of the wheel 110 (step 3). 4 shows an unused state in which the wheel fixing device is attached to the rail, and does not show a state in the middle of the operation of fixing the wheel 110.

  Subsequently, the distal fixed anchor 20 is attached to an arbitrary position in the length direction of the rail 1 (step 4), and the intermediate fixed anchor 50 is attached to the rail 1 so as to be disposed between the retractor 10 and the distal fixed anchor 20. (Step 5). Any of steps 2 to 5 may be performed first or all of them may be performed simultaneously.

  Subsequently, the tension applying handle 13 of the retractor 10 is operated to apply tension to the retractor belt 11 (step 6). Here, the length of the fixed belt 30 and the length of the connection belt 40 are the same as those of the fixed belt 11 when the retractor belt 11, the fixed belt 30, and the connection belt 40 are put on the outer peripheral surface of the wheel 110 as shown in FIG. The retractor belt 11 disposed in the vicinity of one end and the other end of the wheel 110 is set so as to be in contact with the outer peripheral surface of the upper half of the outer peripheral surface of the wheel 110. Further, the length of the connecting belt 40 is such that when the retractor belt 11, the fixing belt 30 and the connecting belt 40 are put on the outer peripheral surface of the wheel 110 as shown in FIG. It is set to be pulled upward.

  As described above, in the present embodiment, force is concentrated on two locations on the outer peripheral surface of the wheel 110 with which the retractor belt 11 in the vicinity of one end and the other end of the fixed belt 11 is in contact. Therefore, the retractor belt 11 bites into the outer peripheral surface of the wheel 110 at the two wheel pressing positions, and the retractor belt 11 and the wheel 110 are securely fixed so as not to move relatively even with the retractor 10 operated manually. be able to.

  In the present embodiment, the connecting belt is arranged such that the center portion of the fixing belt 30 is pulled upward by the connecting belt 40 when the retractor belt 11, the fixing belt 30, and the connecting belt 40 are put on the outer peripheral surface of the wheel 110. A length of 40 is set. For this reason, force is also concentrated on the outer peripheral surface of the wheel 110 with which the connection belt 40 contacts.

Compared with the case where the force to the rail 1 side is applied to the retractor belt 11 by 20, the distance between the two rail side force acting positions where the force to the rail 1 side is applied to the retractor belt 11 becomes closer.

In the case of this embodiment, as shown in FIG. 5, the distance between the two rail-side force acting positions is smaller than the distance between the two wheel pressing positions. For this reason, when the wheel 110 tries to move in the front-rear direction, a force in the pulling direction is easily applied to the retractor belt 110, and the amount of movement of the wheel 110 in the front-rear direction can be further reduced.
Even when the distance between the two rail side force acting positions is larger than the distance between the two wheel pressing positions, the downward force applied to the retractor belt 11 can be further increased.

  Further, since the intermediate fixed anchor 50 is provided, the direction in which the retractor belt 11 extends with respect to the retractor body 12 of the retractor 10 is constant, and the posture of the retractor 10 when the wheels are fixed is constant. For this reason, operation of the retractor 10, for example, operation of the tension applying handle 13 and the release lever 14 becomes easy. Further, since the positions of the tension applying handle 13 and the release lever 14 are also constant, the operation can be easily performed even when the retractor 10 is disposed in a narrow space and is difficult to see. Further, it is advantageous in preventing malfunction of the retractor 10.

In this embodiment, the fixing belt 30 and the connection belt 40 have a different color from the retractor belt 11, so that the user is not used to the installation work, and even when the installation work is performed while looking at the instruction manual etc., the installation is smoothly performed. It can be carried out. Further, even when the user is used to the installation work, mistakes in installation are effectively prevented.
A length adjusting member such as a buckle for adjusting the length of the fixing belt 30 may be provided in the middle of the fixing belt 30. In this case, by adjusting the length of the fixing belt 30 in accordance with the size of the wheel 110, the wheel 110 can be reliably fixed regardless of the size.

In the present embodiment, the number of connection belts 40 is one, but two or more connection belts 40 may be provided. Furthermore, it is possible to provide two or more fixing belts 30.
The wheel fixing device can be used in combination with a conventional wheelchair fixing device, that is, a wheelchair fixing device that fixes a wheelchair by connecting a wheelchair frame and a vehicle floor.

  Moreover, although what provided the intermediate | middle fixed anchor 50 was shown in this embodiment, it is also possible to fix the wheel 110, without providing the intermediate | middle fixed anchor 50. FIG. In this case, the retractor 10 and the tip fixing anchor 20 are the two rail side force acting positions. When the retractor 10 and the tip fixing anchor 20 are attached to the rail 1 so that the distance between the retractor 10 and the tip fixing anchor 20 is shorter than the distance between one end and the other end of the fixing belt 30, the wheel 110 moves back and forth. When moving, a force in the pulling direction is easily applied to the retractor belt 11, and the movement of the wheel 110 in the front-rear direction is efficiently suppressed.
