Description

Wheelchair with bumper

[0001] The present invention relates to a wheelchair having a bumper part, and more particularly, to a wheelchair having a bumper part that can safely protect the feet of a patient using the wheelchair even when the wheelchair deviates from the normal path and collides with a surrounding obstacle due to a mistake or malfunction while the patient is riding the wheelchair, thereby reducing the risk of using the wheelchair, increasing the satisfaction of using the wheelchair, and ensuring safe driving.

[0002] Wheelchairs are devices that assist people with limited leg freedom or physical disabilities in moving around. Demand for wheelchairs continues to grow due to the increasing number of people with mobility challenges caused by the aging population and the rise in the number of people with disabilities.

[0003] A wheelchair is a structure in which wheels are attached to a chair on which the user can sit, and can be broadly classified into manual wheelchairs and electric wheelchairs depending on the method of driving the wheels.

[0004] Manual wheelchairs are the most common type of wheelchair that has been in use for a long time. They are configured with ring-shaped handles on the outside of both wheels so that the user can manually turn the wheels with the handles.

[0005] Manual wheelchairs are generally designed with a foldable structure, which has the advantage of being able to be folded and easily loaded into vehicles, but they have the problem of being difficult to use for long distance travel due to the user's physical exhaustion.

[0006] To solve the aforementioned problems of manual wheelchairs, electric wheelchairs have been developed and are being used that are configured to electrically drive the wheels of the wheelchair using a drive device such as an electric motor.

[0007] However, in the case of manual wheelchairs and electric wheelchairs, there is a problem that the patient's feet cannot be seen clearly when the caregiver holds the handle of the wheelchair from the back while the patient is riding the manual wheelchair, and the patient may collide with obstacles placed nearby, which may cause pain to the patient.

[0008] In the case of electric wheelchairs, the patient rides the wheelchair and controls the direction and speed of movement by directly operating the control device. However, if the patient malfunctions by operating the control device and hits an obstacle in the vicinity, there is a problem in that there is no structure to protect the patient's feet, which can cause pain.

[0009] The purpose of the present invention, which has been devised in consideration of the above points, is to provide a wheelchair equipped with a bumper that can safely protect the patient's feet even when the wheelchair's direction of travel deviates from the normal path and collides with a surrounding obstacle due to a mistake or malfunction while the patient is riding the wheelchair, thereby reducing the risk of using the wheelchair, thereby increasing the satisfaction of using the wheelchair, and ensuring safe driving.

[0010] In order to achieve the above object of the present invention, a wheelchair having a bumper part is characterized by including: a seating part having handles formed to extend a certain length on both rear sides and supporting the buttocks and waist when a patient sits; a wheel part including driving wheels rotatably installed on both sides of the seating part to enable movement, and auxiliary wheels rotatably installed on both front sides of the seating part to enable rotation so as to change direction; a footrest part arranged on the front lower side of the seating part so that a patient can place their feet when sitting on the seating part; and a bumper part arranged around the footrest part so as to wrap the patient's feet when the patient places their feet on the footrest, thereby protecting the feet from external impact.

[0011] Here, the footrest portion is hingedly installed on the front lower side of the seating portion so as to be foldable, and the bumper portion can be detachably installed around the circumference of the footrest portion.

[0012] And, the bumper part is formed to have a cross-section in the shape of the letter 'C', and one side of the bumper part is opened and inserted into the foot part, so that the bumper part can be fixedly placed in the foot part.

[0013] In addition, the bumper part is provided with an air cushion that expands when air is injected, and can be selectively expanded by injecting air into the interior of the air cushion or contracted by removing air.

[0014] In addition, a plurality of bulkheads may be formed inside the bumper portion so that even if one side is damaged, the air inside the air cushion is not completely lost, but only the damaged area is lost.

[0015] And the bumper part can be formed to have a curved cross-section so as to wrap around the circumference of the footrest part.

[0016] As described above, the wheelchair equipped with a bumper according to the present invention can safely protect the patient's feet even when the wheelchair's direction of travel deviates from the normal path and collides with a surrounding obstacle due to a mistake or malfunction while the patient is riding the wheelchair, thereby reducing the risk of using the wheelchair, thereby increasing the satisfaction of using the wheelchair, and enabling safe driving.

[0021] Hereinafter, a wheelchair equipped with a bumper according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0022] FIG. 1 is a perspective view illustrating the structure of a wheelchair having a bumper part according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating the structure of a bumper part of a wheelchair having a bumper part according to an embodiment of the present invention, FIG. 3 is a side view illustrating the structure of a bumper part of a wheelchair having a bumper part according to an embodiment of the present invention, and FIG. 4 is a plan view illustrating the structure of a bumper part of a wheelchair having a bumper part according to an embodiment of the present invention.

[0023] As shown in these drawings, a wheelchair having a bumper according to an embodiment of the present invention is configured to include: a seating portion (100) having handles (110) formed to extend a certain length on both rear sides and supporting the buttocks and waist when a patient sits; a wheel portion (200) including driving wheels (210) rotatably installed on both sides of the seating portion (100) to enable driving, and auxiliary wheels (220) rotatably installed on both front sides of the seating portion (100) to enable turning; a footrest portion (300) arranged on the front lower side of the seating portion (100) to allow a patient to place their feet when sitting on the seating portion (100); and a bumper portion (400) arranged around the footrest portion (300) to wrap the patient's feet when the patient places their feet on the footrest portion (300) to protect the feet from external impact.

[0024] The seating section (100) has a handle (110) formed at the upper rear side with a certain length that can be gripped by hand to move the wheelchair when a caregiver moves the patient while the patient is seated on the seating section (100).

[0025] And the handle is formed at a certain angle toward the rear so that the guardian can grip it with his / her hand in a comfortable position, and it is effective to apply an elastic material covering to the outer surface to prevent slipping or to form the surface of the handle in a curved shape.

[0026] In addition, the seating section (100) is provided with a seat (120) that is formed flat so that the patient can sit on it, and armrests (130) are formed on both sides of the seat (120) so that the patient's arms can be comfortably placed on the armrests (130).

[0027] The wheel part (200) is configured with a drive wheel (210) that is rotatably installed on both sides of the seating part (100) to enable the wheelchair to be moved to a desired location and has a relatively large diameter, and an auxiliary wheel (220) that is rotatably installed on the front lower side of the seating part (100) and has a relatively small diameter.

[0028] The driving wheel (210) supports the weight of a patient seated on the seating section (200) when the wheelchair is moved, and the auxiliary wheel (220) is installed in front of the seating section (200) so as to be rotatable so as to change the direction of movement of the wheelchair when the wheelchair is moved.

[0029] As described above, the footrest (300) is positioned at the front lower side of the seating section (100) to allow the patient to place his / her feet when sitting on the seating section (100). It is preferable that the footrest (300) be hingedly installed at the front lower side of the seating section (100) so as to be foldable.

[0030] The footrest (300) is installed rotatably on the front lower side of the seating portion (100) and is foldable, so that the wheelchair can be stored in a reduced volume state by folding the footrest (300) when not in use.

[0031] The bumper part (400) is arranged around the footrest part (300) and is provided to wrap the foot when the patient places the foot on the footrest part (300), thereby protecting the foot from external impact.

[0032] This bumper part (400) is installed so as to be detachable around the perimeter of the footrest part (300), so that when the wheelchair is not in use and is stored, the overall volume of the wheelchair can be reduced by removing the bumper part (400) from the wheelchair, thereby making it easy to store the wheelchair.

[0033] In addition, it is preferable that the bumper part (400) be formed to have a cross-section in the shape of the letter 'C', and that one side of the bumper part (400) be inserted into the foot part (300) so that the bumper part (400) is fixedly placed on the foot part (300).

[0034] Since the cross-sectional shape of the bumper part (400) is formed in a 'C' shape, it is effective in that the bumper part (400) can be fixed to the footrest part (300) by using one open side, while the other side corresponding to the one open side is formed closed to sufficiently absorb external impact.

[0035] This bumper part (400) can be formed of various materials, but in the case of the bumper part according to the present invention, the bumper part (400) is provided with an air cushion (410) that expands when air is injected, so that air can be selectively injected into the interior of the air cushion (410) to expand it, or air can be removed to contract it.

[0036] A plurality of partition walls (410) are formed inside the bumper section (400) so that even if one side is damaged, the air inside the air cushion (410) is not completely lost, but is only lost in the damaged area.

[0037] That is, by installing a partition wall (410) that divides the internal space of the air cushion (410) at multiple locations within the bumper portion (400) formed by the air cushion (410), even if the air cushion in one area is damaged, the air in the entire air cushion (410) is prevented from escaping and the air cushion can no longer function as a bumper.

[0038] In addition, it is effective to form the bumper part (400) to have a curved cross-section overall so that it wraps around the circumference of the footrest part (300), thereby protecting the front side of the wheelchair when the wheelchair is moving.

[0039] The air cushion (410) constituting the bumper portion (400) of the wheelchair equipped with the bumper portion according to the present invention is formed in a 'C' shape in cross-section and is fixed to the footrest portion (300) through its opening, but in order to prevent it from being detached from the footrest portion (300), it is preferable to attach it to the footrest using a separate Velcro tape, or to provide a separate fastening hook on one side of the footrest portion (300) and the air cushion (410) so that the fastening hook is additionally coupled to prevent detachment of the bumper portion (400).

[0040] The process of a guardian moving a patient to a desired location using a wheelchair equipped with a bumper part according to one embodiment of the present invention having such a configuration is described as follows.

[0041] First, in order for a guardian to move a patient, the patient is seated on the seat (120) of the seating unit (100) and then air is injected into the air cushion (410), which is the bumper unit (400), so that the air cushion (410) expands and can function as a bumper.

[0042] Then, an air cushion (410) that is inflated by air is inserted in front of the footrest (300) so that the bumper part (400), which is the air cushion (410), is installed in front of the footrest (300).

[0043] In this state, the guardian moves the patient to the desired location, and even if the wheelchair collides with an obstacle while moving, the patient's feet can be protected from the impact because the external impact is absorbed by the bumper part (400) made of an air cushion (410).

[0044] And, after the patient's movement using the wheelchair is completed, the bumper part (400) is removed from the footrest part (300), the air is removed to minimize the volume, and then the wheelchair is stored. Then, the footrest part (300) of the wheelchair is rotated and folded, and the wheelchair can be stored in a separate location.

[0045] A wheelchair having a bumper according to one embodiment of the present invention having a configuration as described above can safely protect the patient's feet even when the wheelchair's direction of travel deviates from the normal path and collides with a surrounding obstacle due to a mistake or malfunction while the patient is riding the wheelchair, thereby reducing the risk of using the wheelchair, thereby increasing the satisfaction of using the wheelchair, and ensuring safe driving.

[0046] The above is only a description of some of the preferred embodiments that can be implemented by the present invention, and as is well known, the scope of the present invention should not be construed as being limited to the above embodiments, and the technical idea of ​​the present invention described above and the technical idea that is the basis thereof are all included in the scope of the present invention.

[0047] The present invention is applied to wheelchair technology that can protect a patient even when colliding with an obstacle by using a bumper.
