Description

  The present invention helps prevent accidents caused by falls and falls of elderly people and people with disabilities who use wheelchairs. It relates to a wheelchair automatic brake device that can be attached to a wheelchair currently in use.

  Conventionally, some of these products have been commercialized, but it requires cost and processing to be installed on the wheelchair users are currently using, and the time lag until the parking brake is locked. Has occurred. The automatic brake device for wheelchairs of the present invention is characterized by the fact that it can be easily mounted on a wheelchair that is currently in use at a low cost, prevents falling due to forgetting to apply the brake, and ensures more reliable safety It has become.

  The wheelchair user can easily attach the wheelchair that is currently used without modifying it, and the time lag until the brake is locked can be eliminated by using a belt linked to the seating surface. Can be folded and stored when the wheelchair user is not using it. In addition, since it has a simple structure, it can be offered at a low price. This will reduce the burden on the person and the caregiver and improve the rich daily life of the handicapped person, and the present invention intends to solve the above-mentioned drawbacks.

  The present invention makes it possible to detect the slight transfer movement when a wheelchair user tries to get off the wheelchair by making the seating surface of the wheelchair independent and interlocking the belt via the armrest with the brake bracket, and safely brakes by eliminating the time lag Can be automatically applied. In addition, it can be easily attached to existing wheelchairs and has a simple structure, so it can be offered at a low price. The present invention solves the above-mentioned problems by preventing a fall accident, a fall accident, etc. due to a wheelchair user forgetting to apply the parking brake when getting off the wheelchair.

  As mentioned above, even if a wheelchair user forgets to apply the parking brake when moving from the wheelchair, the brake is automatically locked, so it becomes a defensive measure to prevent a fall accident or fall accident. Can use a wheelchair with confidence. Moreover, since the function of a wheelchair can be used without impairing the conventional function, it is useful for caregivers and hospital facility workers in terms of safety management and reduction of mental and physical burdens.

The wheelchair automatic brake device of the present invention has a seating surface independent, the front part of the seating surface is fixed to the seating frame of the wheelchair body, the rear part of the seating surface is lifted and tilted forward, and while the user is on the wheelchair, The parking brake is released via the belt attached to the seat surface.
When the user gets out of the wheelchair, the seating surface is lifted via the belt by the force of the coil spring attached to the brake, and the parking brake is automatically locked. Also, when trying to stand up from a wheelchair, the seating surface is lifted by the force of the coil spring, so that the standing can be assisted, and when sitting, the seating surface is inclined forward so that it is easy to sit down. The seat is made of a wooden seat that is divided into two vertically, and a cover is attached. Since the belt is built in, the wheelchair user sits down and gets down, and the brakes act evenly on the left and right brakes. The belt uses a highly durable belt and is linked to the brake body. For mounting the brakes, wheelchairs from any manufacturer can be installed using mounting brackets, etc., so that the wheelchair body does not need to be processed.

Hereinafter, an embodiment will be described with reference to the accompanying drawings. 6 wooden seats are newly installed on the upper side of 1 existing seating surface, and 15 existing seating surface set screws are used to fix the two left and right front surfaces of 6 wooden seating surfaces and are attached to 6 wooden seating surfaces. Set 7 belts so that 6 wooden backs are raised. In the belt No. 7, a gap for passing the belt was provided by 10 spencers attached between the armrest 11 and the body frame 8. A belt is passed between 11 armrests and 8 body frames and fixed to 9 ring fittings. The ring fitting 9 is fixed to the front side of the interlocking brake 2 via a fulcrum screw 4. The front side of the interlocking brake of 2 and the upper side of the coil spring of 3 are fixed, and the lower side of the coil spring of 3 is fixed to the body frame of 8 with a spring mounting band of 5.
When the user gets out of the wheelchair, the belt of 7 through the body frame of 8 is pulled by the force action of the coil spring of 3, and the rear part of the wooden seat of 6 is lifted up and the front side of the interlocking brake of 2 is The front L-shaped part of the interlocking brake 2 rises and locks the tire 18 with the fulcrum screw 4 lowered and the lever principle. For this reason, even if the user forgets to apply the parking brake and gets off the wheelchair, the brake is automatically applied, which helps to prevent the user from falling.

  When using a wheelchair, sit down on the wooden seat of 6 and the back of the 6 wooden seat will sink with the weight of the user, and the coil spring of 3 will be pulled through the belt of 7 and the front side of the 2 interlocking brake will be raised 2 at the same time. The front L-shaped part of the interlocking brake is lowered and the brake is released, so that the wheelchair can run.

When the user is not using the wheelchair, the movement of the wheelchair is as follows. The two interlocking brake rear parts connected to the wire attached to the 16 levers are lifted upward and the front L of the two interlocking brakes is moved upward. The mold part lowers and the brake is released, allowing the wheelchair to move. As a result, even when the user is not using the wheelchair, the user can move while releasing the brake.
Since one embodiment of the present invention is configured as described above, the brakes are automatically locked even if the parking brake is forgotten when the user gets off the wheelchair. It can greatly contribute to mitigation and can improve abundant daily life.

  The present invention is required for elderly people, persons with disabilities, and people who need assistance, and can be used with simple wearing and is considered to be commercialized at low cost. In addition, because it is simple in structure, there are few troubles, and the result of repeated tests with a prototype wheelchair was good. This type of conventional brake has a slight time lag and high cost until the brake is operated, but the time lag can be eliminated by tilting the wooden seat 6 forward. The possibility of use is extremely high because it eliminates the risk of hospitals and facilities and prevents accidents involving the elderly and persons with disabilities.
