Abstract

PROBLEM TO BE SOLVED: To easily self-propelled or aided on an outdoor uneven road surface or soft ground with a four-wheel wheelchair such as an ordinary self-propelled wheelchair, an assisting wheelchair, and a reclining wheelchair used in a flat room There wasn't. In addition, vibration and dynamic shock from the front wheels are large, and the handling and comfort of the handicapped or caregiver are impaired. A wheelchair with a propulsion device is heavy and dangerous when it falls.
SOLUTION: A 5-wheel wheelchair in which one wheel having a diameter (180 mm to 220 mm) and a wheel width (30 mm to 60 mm) larger than the diameter of a front wheel of an ordinary four-wheel wheelchair is attached to the center of both front wheels. A five-wheeled wheelchair that travels as a car and is a five-wheeled vehicle that maintains stability as a four-wheeled vehicle when tilted, and one wheel can be easily removed, attached, or folded. Regardless of whether it is a manufacturing process car or a use process car, it can be a 5-wheeled wheelchair. It is desirable to make the wheelchair rear wheels as thick as the mounting bike tires.

Description

  The present invention relates to a five-wheeled wheelchair such as a self-propelled wheelchair, an assistive wheelchair, and a reclining wheelchair.

  It has not been easy to self-propelled or aided on an uneven road surface or soft ground with a four-wheeled wheelchair such as an ordinary self-propelled wheelchair, an assisting wheelchair, and a reclining wheelchair used in a flat room. Most of the causes are that the height of obstacles (pebbles, etc.) on the path is close to the radius of the front wheelchair wheel and the width of the front wheels (tires, etc.) is thin (small), so it gets stuck in various grooves and depressions. Is the case. As a result, the vibration and dynamic shock from the front wheels were large in the outdoors, and the maneuverability and comfort of the handicapped or caregiver were impaired. A wheelchair with a propulsion device is heavy and dangerous when it falls.

  If a normal wheelchair used in a flat room is used outdoors, it is difficult and requires a lot of effort to self-run or assist on rough roads such as uneven road surfaces. The main cause of this problem is that the radius and wheel width (thickness) of the front wheels are small. It is intended to improve the disqualification of wheelchair functions, which are the cause of inconvenience and discomfort when disabled people or caregivers use wheelchairs outdoors.

(1) The radius of a normal wheelchair front wheel used in a flat room is equivalent to the height of obstacles in the field (pebbles etc.), so it is not easy for the front wheels to get over obstacles. Utilize wheels larger than the diameter of a normal wheelchair front wheel (eg, wheel diameter 180 mm to 220 mm and wheel width 30 mm to 55 mm).
(2) A wheel having a radius larger than the radius of the front wheel of an ordinary wheelchair and a wheel width is attached to the center of both front wheels to form a five wheelchair [FIG. 1].
(3) The pedestal of one wheel mounted in the center keeps the horizontal plane 6.
(4) Since the attached front wheels are larger than the normal wheelchair front wheels, the two front wheels of a normal wheelchair float inside with a gap 9 of several centimeters to 10 cm [Fig. 3]. It is a five-wheeled vehicle that functions as a three-wheeled vehicle with two rear wheels, has the functions of a three-wheeled vehicle, is highly maneuverable, and has a high-safety four-wheeled vehicle function when the vehicle body is inclined on a sloping ground.

  When one front wheel larger and thicker than a normal front wheel is attached, the front wheel can be easily detached and attached or folded.

(1) By increasing the diameter of the front wheel and increasing the width of the front wheel, a wheelchair such as a self-propelled vehicle or an assistance vehicle can be easily operated / passed on an outdoor uneven road or a soft road. Vibration and shock are reduced.
(2) If one wheel that is larger and thicker than normal front wheels is attached, it becomes a five-wheeled vehicle, but in actual running, one front wheel and two rear wheels are grounded to demonstrate the function (mobility) of a tricycle. .
(3) Although it is not a preferable operation of the wheelchair, the left front wheel or the right front wheel can support the weight of the eccentric wheelchair even when the vehicle runs on an inclined surface, and the four wheels compensate for the instability of the three-wheeled vehicle.

(1) One front wheel is foldable or removable, and is easy to carry.
(2) The present invention can be used for two front wheels of a four-wheel wheelchair.
(3) The present invention can be applied to the rear wheel of a four-wheel wheelchair to utilize a wide wheel such as a mounting bike tire.

(1) Process of use Regardless of whether it is a wheelchair or a newly manufactured wheelchair, one of the best forms is a five-wheeled wheelchair with one wheel that is larger than a normal front wheel and can be easily detached. It is.
(2) Process of use Regardless of whether it is a wheelchair or a newly-manufactured wheelchair, it is a five-wheeled vehicle fitted with one wheel that is larger and thicker than a normal front wheel, and the two rear wheels are wide wheels (e.g., equivalent to a mounting bike wheel). Is one of the best forms.

(1) Keeping the front and rear wheels of the self-propelled wheelchair in use (including rear-tilt rear wheels), the vertical support shaft (pipe) 8 on which both front wheels are located and the horizontal support shaft in the traveling direction ( Below the horizontal support shaft (pipe) 7 intersecting with the pipe 7, a single beam (plate-shaped, round and round structure material) 6 to which one large front wheel is attached is attached [FIG. 3].
(2) When the horizontal support shaft 7 in the traveling direction of the front wheels is not horizontal, the pedestal of one front wheel attached to the beam is attached by the getter 10 so as to be kept horizontal [FIG. 4].

(1) A beam (plate-shaped, round and round structure material) 6 to which one front wheel is attached is a beam that is fixed to both horizontal support shafts that support the wheelchair wheel (the wheelchair cannot be folded). ), Or a beam that can be easily attached and detached, or a beam that can be folded at the same time as the wheelchair is folded.
(2) Mounting that allows fixing the pedestal of one front wheel to the beam and mounting and removing the pedestal arbitrarily.

(1) In-use process Regardless of the wheelchair or the newly manufactured wheelchair, the front two wheels and the rear two wheels are changed to large and thick two wheels and two mounting bike wheels, respectively.
(2) In-use process Regardless of whether it is a wheelchair or a newly manufactured wheelchair, only the front two wheels have been changed to larger and thicker two wheels.

  (1) The present invention relates to a wheelchair that facilitates outdoor activities for persons with disabilities and is effective in promoting mental and physical health. There are strong expectations for the present invention from disabled people and caregivers, and it can contribute to society in terms of productivity.

  “It is a side view showing a five-wheel-assisted wheelchair.”   “It is a front view showing a five-wheel-assisted wheelchair.”   “It is a front view showing how to attach one front wheel to the assisting wheelchair and the positions of three front wheels.”   “It is a drawing showing an example of a method for horizontally mounting a pedestal of one front wheel on a wheelchair in use.”

Claims (2)

  Regardless of whether the vehicle is manufactured or used, a four-wheeled wheelchair 1 such as a self-propelled wheelchair, an assistive wheelchair, or a reclining wheelchair has a wheel 3 having a radius larger than the radius of the front wheel 4 and a wheel width. Wheelchair [FIG. 1] and [FIG. 2] attached to the wheel, one wheel can be easily removed, attached or folded, and the wheel base 1 is a horizontal wheelchair [FIG. 3] and [ FIG. 4].   The size of the front wheel 1 to be attached is larger than the height of obstacles (pebbles, etc.) on the outdoor passage, wheels having a diameter of 180 mm to 220 mm and a width of 30 mm to 60 mm.
