The present invention relates to a backrest lifting device of a wheelchair, and more particularly, to a backrest lifting device of a wheelchair to be moved backward through the backrest by a lifting operation of the backrest.

In general, a wheelchair is one of transportation devices used by a disabled person or a person with a disability. As is well known, such a wheelchair can be driven while the user who rides the seat can drive the wheel by himself or herself, and it is also possible to travel by an assistant.

Therefore, in the wheelchair, as shown in FIG. 1, wheels 2 installed on both sides of the wheelchair frame 1 are provided with an annular driving handle 3 so that a user who rides on the seat 4 rotates the wheel 2. A pair of handles 5 are provided on the rear side of the wheelchair frame 1 and can be gripped by an assistant.

When using a wheelchair, it is a reality that wheelchair users are inconvenient because the facilities for the disabled and the facilities for the disabled are not properly equipped in Korea.

In particular, there are toilets for the disabled in using the toilet, but in order to provide a toilet for the disabled, a wheelchair is required to have enough space to rotate, and thus there is a difficulty in securing a space.

Therefore, various attempts have been made to minimize the space of the toilet, and a toilet is proposed to allow the use of the toilet without rotating the wheelchair in the toilet, such as Korean Patent Publication No. 2007-32763 (front seated toilet). .

However, because the separate toilet for the disabled is limited to a specific place, it is very inconvenient to find a toilet for the disabled one by one, but it is very difficult to move from the wheelchair to the toilet to use the public toilet.

Accordingly, the present invention has been made in order to improve the above problems, the present invention has a main object to provide a backrest lifting device of a wheelchair to move only the body back by allowing the backrest up and down.

In another aspect, the present invention is another object to provide a convenience of using the toilet seat to move easily by moving backwards without moving the wheelchair in a narrow toilet.

And another object of the present invention is to provide a backrest lifting device of the wheelchair to minimize the toilet space to facilitate the installation of the toilet for the disabled.

In order to achieve the above object, the present invention provides a wheelchair, comprising: a fixed rod provided to be movable up and down inside a tubular both side back frame; A backrest plate for allowing both ends to be fixed to the fixed rod through a vertical lifting hole formed in a surface facing each other between the backrest frames on both sides; a lift operation tool for manipulating the backrest plate by lifting and lowering the fixed rod; The rear of the backrest frame is formed with a guide hole for guiding the elevating operation tool is raised and lowered, the engaging hole extending the guide hole to the side corresponding to each other between the backrest frame of both sides at the upper end and the lower end of the guide hole Is formed, the fixed rod is coupled to the ring to enable the rotation is impossible to move up and down at a constant height, the ring is characterized in that the lifting operation tool is coupled to protrude to the outside through the guide hole on one side It is done.
The fixing rod is installed so that the back plate is lowered to a height lower than the seat seat, so that the rear of the seat seat is fully open.

By using the wheelchair according to the above configuration, it is possible to easily remove the back while entering the backward direction, so that the wheelchair user can easily move to the rear of the wheelchair, thereby enabling the wheelchair users to move and perform in a relatively narrow moving space. Make this convenient.

In addition, the present invention can minimize the toilet space because the wheelchair rotation space in the toilet is unnecessary, it is possible to provide a toilet for more wheelchair users.

With reference to the accompanying drawings will be described in more detail the back lifting device of the wheelchair according to the present invention.

The wheelchair of the present invention is similar to the conventional wheelchair configuration.

In other words, the wheelchair first has a seat fixing frame for fixing seats on both sides, an armrest frame and a wheel fixing frame respectively provided on the upper and lower portions of the seat fixing frame, and a rear end of the seat fixing frame, the armrest frame and the wheel fixing frame. It is a configuration in which the vertical back frame and the foot support frame to which the parts are simultaneously connected are integrally connected.

The armrest frame is formed in the armrest in the longitudinal direction, 횔 fixed frame is fixed to the front wheel of the small diameter in front of the main wheel of the large diameter is fixed to the rear, especially in the large diameter main wheel on the outer side of the drive handle This is provided.

Then, the back frame is formed of a backrest made of leather or metal, and the upper end portion is bent rearwardly so that a pair of handles are formed to allow the assistant to grip.

On the other hand, the lower end of the scaffold support frame formed to extend the seat fixing frame downward to the wheel fixing frame side end is provided with a scaffold to rotate in a corresponding direction.

In particular, the front side of the seat fixing frame is provided with a braking handle for braking the main wheel, and at the bottom of the seat fixing frame, a folding link is connected between the seat fixing frame and the wheel fixing frame by an intersecting link method. This wheelchair can be folded in half.

It is a feature of the present invention to enable the back to be movable to the rear while the backrest is vertically elevated to the configuration of the wheelchair according to the above configuration.

Figure 2 is a partially enlarged perspective view showing a backrest lifting device according to the present invention, Figure 3 is a plan view showing a backrest lifting device horizontally cut the upper end of the backrest frame of one side according to the present invention.

As shown in the present invention, it is possible to lift and operate the back of the wheelchair.

To this end, the backrest frame 10 provided in parallel to both sides from the rear of the wheelchair is provided with a hollow tubular shape inside.

The backrest frame 10 on both sides of the backrest frame 10 faces each other so that vertical lifting holes 11 are formed to communicate with the inside in the longitudinal direction of the backrest frame 10 with a fine width.

The fixing rod 20 is inserted into the back frame 10 so that the lifting and lowering is possible, and both of the fixing rods 20 inserted into the back frame 10 on both sides pass through the lifting hole 11 to support the back plate 30. Both ends of the) are combined.

Therefore, the fixing rods 20 on both sides connected to the backrest plate 30 are inserted into the backrest frame 10 so as to be lifted and lowered together with the backrest plate 30.

At this time, the lifting operation tool 30 is a configuration that allows the lifting operation to raise and lower the fixed rod 20.

As shown in FIG. 2, the elevating manipulation tool 30 is elevated and guided through the guide hole 12 formed at a predetermined width as a height greater than the height of the back plate 30 at the rear of the back frame 10.

This lifting operation tool 30 is configured to be coupled to one side of the ring 21 is rotatably coupled while not moving up and down at a certain height of the fixed rod (20).

Therefore, the lifting operation tool 40 moves only in the up and down direction so that the fixed rod 20 moves up and down inside the back frame 10, and the rotating rod 20 stops the ring 21 by the rotation operation. ) Is configured to rotate together.

However, in the upper end and the lower end of the guide hole 12 formed in the backrest frame 10 of the present invention, as shown in FIG. 4, the engaging hole 13 horizontally extending the guide hole 12 is formed.

Therefore, when the lifting operation tool 40 is positioned in the locking hole 13, the back plate 30 together with the fixing rod 20 maintains a fixed state.

On the other hand, the lower end of the fixed rod 20 so that a stable ground with the ground can be applied to the fixed rod 20 when the lifting rod 40 is positioned at the lower end of the guide hole 12 a predetermined pressure or more Most preferably.

Referring to the operation according to the above configuration is as follows.

In the wheelchair according to the present invention, the back plate 30 is normally positioned above the seat seat and is maintained to support the back of a patient or a disabled person.

If you need to go to the toilet while moving in a wheelchair in this state, you can use the normal toilet even if the toilet is not for the disabled.

That is, since the general toilet has a very wide width, only the space where the wheelchair can barely enter, so when going to the toilet in a wheelchair, back to the toilet as shown in Figure 5 to approach the toilet.

When the toilet close to the maximum, both hands are held back and the lifting operation tool 40 is provided to protrude toward the rear side of the backrest frame 10.

At this time, since the elevating operation tool 40 is located in the guide hole 12 at the upper end side locking hole 13 of the back frame 10, when the elevating operation tool 40 is pushed or pulled to the side, the elevating operation tool 40 is The locking hole 13 is moved toward the guide hole 12 side.

When the lifting operation tool 40 is positioned from the locking hole 13 to the guide hole 12, the lifting operation tool 40 is not caught at all, and thus the guide hole 12 is removed by the weight of the fixed rod 20. You can move downward.

That is, when the hand holding the elevating operation tool 40 in the state of moving the elevating operation tool 40 from the locking hole 13 to the guide hole 12 side is released, the lifting rod 40 is coupled to the fixed rod ( 20) falls by its own weight and the lower part hits the ground and descends as much as possible.

Figure 6 is a side view showing a state in which the fixing rod is lowered in accordance with the present invention, Figure 7 is a rear perspective view of the lower back plate.

When the lower end of the fixed rod 20 touches the ground, the lifting operation tool 40 falling with the fixing rod 20 is located at the lower end of the guide hole 12. At this time, the lifting operation tool 40 is lowered as much as possible. Push to push or pull the side in the state of the contact with the ground of the fixing rod 20 to further enhance the pull hole to be located in the locking hole 13 of the lower end of the guide hole (12).

When the lifting operation tool 40 is located at the lower end side locking hole 13 as shown in FIG. 4, even if the weight applied to the wheelchair increases, the fixing rod 20 is firmly fixed so that only the contact force with the ground is increased. It is possible to maintain a stable landing.

On the other hand, if the fixed rod 20 is lowered as much as possible, since the back plate 30 is already positioned below the seat seat 50 as shown in FIG. 5, the rear of the seat seat 50 is completely opened.

As such, when the back plate 30 of the rear of the seat seat 50 is removed from the wheelchair, the patient or the disabled may move backward while the back plate 30 is removed while maintaining the sitting direction.

In particular, since the load acts more largely to the portion supported on the ground by the fixed rod 20 when moving to the rear to enable a safe movement to a more stable landing.

The method of returning to the wheelchair after finishing work is to move both hands back to the back of the back frame 10 as opposed to removing the back plate 30 while moving to the rear of the open wheelchair. The lifting operation tool 40 located in the lowermost end engaging hole 13 of the gripping is gripped.

Lift operation tool 40 is rotated to the side corresponding to each other to be out of the locking hole 13 to be located in the lower end of the guide hole 12.

In such a state, when the elevating operation tool 40 on both sides is simultaneously raised, the back plate 30 is raised together with the fixed rod 20, and the elevating operation tool 40 is raised to the upper end of the guide hole 12. When the lifting operation tool 40 is rotated horizontally to the side corresponding to each other again, the lifting operation tools 40 are secured to the guide hole 12 at the upper end side locking hole 13. In this state, even if the fixed rod 20 does not hold the lifting operation tool 40, the fall by its own weight does not occur.

If the back plate 30 is fixed to the original position is to proceed to the front of the wheelchair as it is to exit the toilet.

As such, the present invention can easily use the toilet even in a narrow space without rotating the wheelchair, it is possible to further reduce the toilet space for wheelchair users, it is possible to expand the toilet for more wheelchair users as well as more space utilization You can increase it.

On the other hand, by using the present invention can be easily and safely boarding the disabled person when boarding a passenger car, etc. can provide convenience to the movement of the patient in various situations.
