Description
Technical field
This utility model relates to a kind of means of transport, particularly a kind of hand wheelchair.
Background technology
At present, the wheelchair of selling on the market various for disabled persons, its basic comprising are main body of vehicle frame, universal wheel, wheel, medicated cushion, back of the body pad, handrail and a hands circle that is installed on the axletree.When the operator rotated the hands circle of both sides forward, wheelchair travelled forward, and when operator turn round when starting to enclose, wheelchair moves backward.
The wheelchair of said structure is because the hands circle can receive the pollution on ground near ground easily when rotating, and operator's easy handle in rotation process is made dirty.This in addition type of drive is to realize moving ahead or retreating of wheelchair through directly shaking axletree, so operator need the cooperation ability normal running of bigger arm strength and waist, this all is inapplicable for a lot of arms and the unable people with disability of waist.Because the position of hands circle is arranged on operator's the back lower place, the arm and the waist that promote hands ring manipulation personnel for a long time can not feel well; And the hands circle rotates and is intermittent movement, operation inconvenience.
Advance use inconvenience with hand mode; And hand very effort when advancing for a long time; And climbing capacity is poor, and the user of wheelchair generally is weakly people, and it is much in life convenient that common wheelchair can not bring to them; And common wheelchair steering underaction needs to rely on right-hand man's the difference of exerting oneself to realize turning to; And if the simple employing driven by power of wheelchair, after the electric power of battery ran out of accidentally, wheelchair armrest again moved movingly, can only rely on other people help, used also very inconvenience.
Remedy these defectives so be necessary to design a new hand wheelchair.
The utility model content
The technical problem that this utility model will solve is to overcome many deficiencies of the prior art, and a kind of hand wheelchair is provided, and it is simple in structure, and is easy to operate, and user can be controlled the moving direction of said hand wheelchair through joystick.
This utility model provides a kind of hand wheelchair, and said hand wheelchair comprises vehicle frame, medicated cushion, back of the body pad, arm-rest frame, front-wheel, trailing wheel, brake gear and actuating device; Said vehicle frame comprises I-shaped device, foot pedal apparatus, front fork unit and front fork connector device; Said actuating device comprises gear and tooth bar, and said actuating device one side is provided with joystick, and said front fork connector device is connected to said joystick through first action bars; Said vehicle frame is connected to bearing through second action bars, and said bearing fixing is on said vehicle frame; Said second action bars is provided with groove, articulates the 3rd action bars on the said groove, and said trailing wheel is connected to said joystick through the 3rd action bars.
A kind of hand wheelchair that this utility model provides, said I-shaped device and said front fork unit articulate, and said front fork unit and said front fork connector device articulate; Said brake gear is located at said medicated cushion below, and said brake gear is connected with said trailing wheel through said the 3rd action bars.
A kind of hand wheelchair that this utility model provides, said foot pedal apparatus is fixed in said vehicle frame, and it is fixed through said front fork connector device and said front fork unit.
Through mutually combining of above-mentioned each element; The hand wheelchair of this utility model in use; Rock back and forth through said joystick and to act on said actuating device; Because said actuating device connects said trailing wheel through said the 3rd action bars, and it connects said front fork connector device through said first action bars simultaneously, connects said vehicle frame through said second action bars; So said actuating device drives said front-wheel and said trailing wheel move left and right.In addition; Through the rotation within the specific limits of said joystick, move up and down thereby make said gear rotation drive said first action bars, further drive said foot pedal apparatus and move up and down; So the hand wheelchair of this utility model can be operated by user oneself, and easy to use.
Description of drawings
Accompanying drawing 1 is the sketch map of the hand wheelchair of this utility model.
The specific embodiment
Below in conjunction with Figure of description, this utility model is further specified.
Preferably, as shown in Figure 1, a kind of hand wheelchair 1, said hand wheelchair comprise vehicle frame 2, medicated cushion 3, back of the body pad 4, arm-rest frame 5, front-wheel 6, trailing wheel 7, brake gear 8 and actuating device 9; Said vehicle frame 2 comprises I-shaped device 21, foot pedal apparatus 22, front fork unit 23 and front fork connector device 24; Said actuating device 9 comprises gear (not shown) and tooth bar (not shown), and said actuating device 9 one sides are provided with joystick 10, and said front fork connector device 24 is connected to said joystick 10 through first action bars 11; Said vehicle frame 2 is connected to bearing 13 through second action bars 12, and said bearing 13 is fixed on the said vehicle frame 2; Said second action bars 12 is provided with groove 14, articulates the 3rd action bars 15 on the said groove 14, and said trailing wheel 7 is connected to said joystick 10 through the 3rd action bars 15.Said I-shaped device 21 articulates with said front fork unit 23, and said front fork unit 23 articulates with said front fork connector device 24; Said brake gear 8 is located at said medicated cushion 3 belows, and said brake gear 8 is connected with said trailing wheel 7 through said the 3rd action bars 15.Said foot pedal apparatus 22 is fixed in said vehicle frame 2, and it is fixed through said front fork connector device 24 and said front fork unit 23.
Preferably; The hand wheelchair of this utility model in use; Rock back and forth through said joystick and to act on said actuating device; Because said actuating device connects said trailing wheel through said the 3rd action bars, and it connects said front fork connector device through said first action bars simultaneously, connects said vehicle frame through said second action bars; Have gap (not shown) between said first action bars and the said joystick, said tooth bar is arranged in the said gap, and said tooth bar and said joystick interconnect; In addition, said gear and said tooth bar cooperatively interact, and said gear is provided with keyway (not shown), and said joystick is provided with handle (not shown), and said keyway is connected with said handle.In use, when user rotates said handle, drive said gear rotation; Thereby it is up and down through the said tooth bar of said gear driven; Through the conversion of power, said first action bars motion of said rack drives further drives said front-wheel and said trailing wheel move left and right; In addition,, move up and down, further drive said foot pedal apparatus and move up and down thereby make said gear rotation drive said first action bars through the rotation within the specific limits of said joystick.
Through mutually combining of above-mentioned each element; The hand wheelchair of this utility model can or shake said joystick through rotation; And then drive the rotation of said actuating device or move; Move thereby drive the direction that said front-wheel and said trailing wheel want towards user, so the hand wheelchair of this utility model can be by user oneself operation, and easy to use.
