Abstract
The utility model relates to a pedal driving wheelchair, composed of a pedal and a flywheel drive assembly. The flywheel drive assembly comprises an advance flywheel, a coaxial orthodromic retreat flywheel and a clutch sleeve in central of the axis. The retreat flywheel is connected with a drive chain by a group of deflecting wheel sheets. The drive chain wraps the deflecting wheel sheet of the retreat flywheel and the advance flywheel in S shape. By driving the advance flywheel, the deflecting wheel sheet can drive the retreat flywheel to run blankly; by driving the retreat flywheel, the advance flywheel can run blankly. Single action of pedal driving can control the wheelchair to advance or retreat through the clutch bar controlling the different engagement of the clutch sleeve with different flywheels. The designed drive mechanism can be installed to the left side or the right side of the wheelchair.
Description
The utility model belongs to the wheelchair that invalids uses.
The wheelchair that the disabled person uses has motor-driven and manual two classes.The manually operated wheelchair is by taking advantage of chair human driven by shaking to advance or retreat, and meets the invalids upper limbs and just can't adopt when invalid.
The design's purpose is for lower limb can provide a kind of wheelchair by movable invalids, drives wheelchair in the mode of step tread.Second purpose of the design is that the pedal driver train can be suitable for and arranged on left and right sides, thinks that hemiplegia patient is used.
The design's content is that a cover step tread actuating device is installed on wheelchair, and this device comprises step tread, flywheel transmission combination and drives driving chain, with step tread driving flywheel and chain wheelchair moved.Advance or retreat for making mono-pedal action can drive wheelchair, the flywheel transmission combination can be such with the structure of driving chain: flywheel has the coaxial forward installation of two covers, central authorities are equipped with clutch cover at axle, clutch cover trip(ping) lever stick control, and connect with step tread.Trip(ping) lever can be controlled and use arbitrary flywheel to drive.The effect of two flywheels is one and drives forwards, dallies during backward, and one to rear drive, idle running when advancing.A kind of version of driving flywheel as shown in Figure 1.Fig. 1 is to use the mounting structure of right crus of diaphragm.Wherein: trip(ping) lever handle 1, step tread 2, retracing spring 3, the flywheel 4 that advances, clutch cover 5 retreats flywheel 6, gimmal 7, power conversion wheel sheet 8,9, wheel flutter sheet 10,12 turns to chain 11, steering lever handle 13, big trochal disc 14, chain drive-belt 15.The flywheel 4 that advances as shown in the figure passes through forward driving coupling of chain drive-belt 15 with big trochal disc 14.Flywheel 6 and two the co-axially fixed power conversion of falling back are taken turns sheets and are formed the flywheel transmission combination that falls back, power conversion wheel sheet group and the installation of driving flywheel axially parallel.A conversioning wheel sheet 8 connects with gimmal 7 with the reversible drive flywheel, another conversioning wheel sheet 9 connects with the flywheel 4 that advances by chain drive-belt 15 with the flywheel 4 that advances, S-shaped wheel sheet 9 and the flywheels 4 of holding of chain drive-belt 15, this hour wheel sheet 9 and big trochal disc 14 are by 15 one-tenth reverse driving coupling of chain.
The design's running condition is as follows, moves the trip(ping) lever handle and makes clutch cover 5 and flywheel 4 engagements, and then wheelchair advances, wheel sheet 9, the 8 driven rotations of wheel sheet, flywheel 6 idle running.When clutch cover 5 and flywheel 6 engagements, then flywheel 6 drives chain 15 and makes the big trochal disc reversing by chain 7, drive wheel sheet 8,9, flywheel 4 idle running this moment.
For ease of advancing or turning backward, can establish the handle steering hardware, the handle steering hardware is by the handle deflecting bar as shown in Figure 1, chain and wheel flutter sheet are formed, and the wheel flutter sheet has two, and one is installed on the wheelchair guide wheel pedestal, one is installed in handle deflecting bar lower end, connects two wheel flutters with chain.Turning handle can drive guide wheel and turns to during use.
The design's pedal drive mechanism and handle steering hardware can be installed in the wheelchair right side as shown in Figure 1, also can be installed on the wheelchair left side as shown in Figure 2.The design's trip(ping) lever handle and steering lever handle also can design in lower position, with foot-operated control.
The utility model can drive wheelchair and advance, retreats and turn to for the lower limb of invalids utilization health.It is a kind of new apparatus that makes things convenient for the invalids action.
Claims (3)
1, a kind of foot-operated driving wheelchair, comprise step tread, the flywheel transmission combination, drive driving chain with wheelchair, it is characterized in that the flywheel transmission combination is made up of an advancing drive flywheel and one group of flywheel transmission combination that falls back, the flywheel transmission combination that falls back is made up of reversible drive flywheel and two co-axially fixed power conversion wheel sheets; The advancing drive flywheel is forward installed with the reversible drive flywheel is coaxial, there is clutch cover in central authorities at coupling spindle, clutch cover trip(ping) lever stick control, and connect with step tread, power conversion wheel sheet group is installed with driving flywheel axially parallel, a conversioning wheel sheet connects with a chain with the reversible drive flywheel, and another conversioning wheel sheet drives driving chain with the advancing drive flywheel by wheelchair and connects, and wheelchair drives S-shaped conversioning wheel sheet and the advancing drive flywheel of holding of driving chain.
2, wheelchair according to claim 1, it is characterized in that, the handle steering hardware is arranged, the handle steering hardware is made up of handle deflecting bar, chain and wheel flutter sheet, the wheel flutter sheet has two, one is installed on the wheelchair guide wheel pedestal, and one is installed in handle deflecting bar lower end, and two wheel sheets connect with chain.
