Abstract

The utility model relates to a double-purpose stair climbing cart which can be driven by manpower or mechanical power, which is composed of cart wheels, a cart wheel frame, an axle shaft, a chair frame and a moving mechanism. The moving mechanism is in transmission connection with a shaft (3) by a crank (5) and two sets of chains. The crank drives the chains, the shaft (3) and the cart frame to rotate to enable the cart to move along certain track. An indexing disc (16) with a hole and a holding handle (18) connected with the indexing disc are arranged on the rear side of a chair back of the cart. The moving direction and the speed of the cart are controlled by the holding handle and the crank. A gasoline engine which is started by electricity and a turbine speed reducer are arranged on a bottom frame of a chair seat, and the cart is driven to move by mechanical power via the transmission of gears. The utility model can be used as a chair or used for carrying objects to go up and down on stairs or used on flat land. The utility model is especially suitable for disabled people.

Description

The dual-purpose cart for travelling up or down stairs of manpower machine power

The utility model relates to the load-carrying cart for travelling up or down stairs that uses on step, be specially adapted to high-rise building delivery than heavy articles or people.

Along with expanding economy, high-rise building increases gradually, general resident's building does not all have elevator, delivery is gruelling upstairs than heavy articles, disabled person and handicapped the elderly go up inconvenient downstairs, so cart for travelling up or down stairs such as rod-pulling type, lever, collapsible, rocker-arm, electrodynamic type arises at the historic moment, they all have the characteristics of himself.

The utility model purpose provides a kind of manpower, machine is tried hard to recommend moving load-carrying cart for travelling up or down stairs, it is to utilize manpower or machine power to drive chain wheel driving mechanism, two groups of four wheel curves are rolled to advance, climb the building action thereby finish, this car is suitable for the disabled person or the elderly goes up usefulness downstairs, also can be used as the usefulness of going downstairs on the delivery weight.

With reference to accompanying

drawing

1,2,3, the structure of the dual-purpose cart for travelling up or down stairs of the utility model manpower locomotive is such, it is by wheel (1), vehicle wheel frame of two installation wheels (2) and the axle (3) that rotates with vehicle wheel frame, the chair frame (4) and the kinematic mechanism that are located on the axle (3) are formed, it is characterized in that described kinematic mechanism has a crank (7) on the minor axis (6) that is installed in the chair back (5) top right side, crank is by two groups of chains (8), (9) be in transmission connection with axle (3), first group of chain (8) is by being in transmission connection with coaxial mounted minor sprocket of crank (10) and the hinge wheel (13) that is installed on the minor axis (12) at right back seat support of the chair back (5) (11) position, second group of chain (9) by with the coaxial mounted minor sprocket of hinge wheel (13) (14) and be installed in the axle (3) right-hand member hinge wheel (15) be in transmission connection, be welded with a balance calibrated disc (16) with holes at the chair back (5) back medium position, on calibrated disc, have one to be that fulcrum can move up and down and the fixable handle (18) that has spring tongue (17) with the calibrated disc center.

This equipment is except that adopting manpower to promote the vehicle to run, also go up an electronic striking spark ignition engine (20) is installed at seat support underframe (19), spark ignition engine is connected with a worm speed reducer (21) by belt, a minor sprocket (22) is arranged on the speed reducer output shaft, minor sprocket (22) is connected transmission with the Dalian wheel (23) of axle (3) left end with gear, and the Oil Switch of spark ignition engine (24) is installed in the right grip of handle.

When the dual-purpose cart for travelling up or down stairs of the utility model manpower machine power uses, handle is placed on the appropriate location, is suitable for suitable with the user, be inserted in a certain hole on the calibrated disc so that handle is fixed with spring tongue, left hand is held handle, and the right hand is held crank, shake crank, drive vehicle wheel frame by two groups of chains and rotate, step on rank thereby the drive wheel travels forward, the crank clockwise direction rotates, car is gone ahead, otherwise then retreat, control crank speed is with regard to the may command speed of a motor vehicle, and change handle direction just can change the sense of motion of car.

This equipment cart for travelling up or down stairs adopts that manpower shakes, chain speed change and transmission, wheel rolling advances, the balance of seat and the direct of travel of car are controlled by handle, more skilled driving with the person can be served the building with 100kg weight or people, transporting when not competent than the heavy articles manpower, can abandon crank, two hold handle, the transmission of employing machine power can handyly be operated.

The dual-purpose cart for travelling up or down stairs of the utility model manpower machine power can be used as seat, can go downstairs or the level land use in the loading, be specially adapted to the disabled person and use, this bassinet structure is simple, and cost is low, easy to use, the bicycle parking canopy of housing-group can be equipped with this car and rent for the resident, needs long-term use person can provide one for oneself.

Description of drawings:

Fig. 1 is the schematic side view of the dual-purpose cart for travelling up or down stairs of the utility model manpower machine power;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the birds-eye view of Fig. 1.

Example:

Overall height 1m, long 0.7m, wide 0.7m respectively installs 4 steamboats on two vehicle wheel frames, vehicle body deadweight 45kg, crank length 230mm, handle length 550mm; Two upper aperture are arranged on the crank, and width between centers is 80mm between square hole, can use first square hole during fortune weight, and crank is long like this, firmly just economizes; The minor sprocket of two groups of chains is 12 teeth, and hinge wheel is the bicycle chainwheel of 48 teeth, and chain is cycle chain.

The underframe (19) that seat support (11) and installation shaft (3) are arranged on the chair frame (4), chevron shaped support (25) is arranged between underframe and seat support, the chair back connects seat support and underframe, Collapsible support frame (26) is arranged on underframe, underframe also can be made footstool usefulness, and bracing frame overlays on the underframe during use, and the time spent does not put down in Fig. 1 dotted line position and promptly makes bracing frame and use, simultaneously handle is placed on extreme lower position and also makes support usefulness, make chair make seat reposefully and use.

Spark ignition engine is selected motor auto electronic lighter for use, and the reduction ratio of worm speed reducer is 60: 1, and miniature gears is also selected 12 teeth for use on the output shaft, and the hinge wheel that matches with it adopts 48 teeth.

Be evenly equipped with 9 holes on the balance calibrated disc, face between two holes all 15 degree at interval mutually.

If it is folding that this car makes the seat support handrail into, handrail is set level, but the bigger weight of transportation volume then.
