Description

Folding pedal mechanism of wheelchair

Technical Field

The utility model relates to the technical field of wheelchairs, in particular to a folding pedal plate mechanism of a wheelchair.

Background

The pedals in the current wheelchairs are basically fixed, and the pedals have the following problems: 1. for people with different heights, the fixed pedal is not comfortable to ride. 2. Because the fixed pedal extends out of the wheelchair, the wheelchair still occupies a larger space after being folded, and is inconvenient to store. Meanwhile, when the packaging box is packaged and transported, the space of the packaging box needs to be occupied, so that the packaging box is large in size.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the fixed footboard to exist among the current wheelchair above-mentioned technical problem provides a foldable pedal mechanism of wheelchair, and it can be adjusted according to the height of passenger.

The utility model discloses the technical problem that will solve can realize through following technical scheme:

the utility model provides a foldable pedal mechanism of wheelchair, includes the wheelchair, the wheelchair has a wheelchair skeleton and a running-board, its characterized in that the lower part front side of wheelchair skeleton is provided with a running-board and supports the horizontal pole running-board and support the montant sliding configuration on the horizontal pole is supported to the running-board the front end that the montant was supported to a pair of running-board is articulated have the running-board, the running-board can support the front end hinge point upset of montant around it and a pair of running-board.

In a preferred embodiment of the present invention, the pedal support cross bar is fixed to a frame cross bar at the front side of the wheelchair frame, and the frame cross bar acts on the pedal to force the pedal to turn up when the pair of pedal support vertical bars move backward.

In a preferred embodiment of the present invention, the front end of the pedal is hinged to the front end of the pair of pedal supporting vertical rods, and the rear end of the pedal is provided with an upwardly turned arc portion.

In a preferred embodiment of the present invention, a pair of through holes is disposed on the pedal support cross rod, and a pair of pedal support vertical rods respectively pass through the corresponding through holes.

In a preferred embodiment of the present invention, a limiting rod is connected to the rear ends of the pair of pedal support vertical rods.

Due to the adoption of the technical scheme, the utility model provides a running-board can be adjusted by stretching from front to back. So as to be suitable for people with different heights to ride and improve the riding comfort. Meanwhile, when the wheelchair is packaged and transported, the pedal plate can be folded into the wheelchair framework, so that the wheelchair occupies a smaller space and is convenient to store. While reducing the package size.

Detailed Description

The present invention is described in detail below with reference to the attached drawings and the detailed description.

Referring to fig. 1-3, a folding footrest mechanism for a wheelchair is shown including a wheelchair 100 having a wheelchair frame 110 and a footrest 120. The wheelchair frame 100 is further provided with a pair of

wheelchair armrests

130 and 140, a wheelchair cushion 150, and a wheelchair backrest 160.

The utility model is characterized in that: a folding pedal mechanism is provided on the lower front side of the wheelchair frame 110. The method comprises the following steps: a pedal support cross rod 210 is fixed on the frame cross rod 111 at the front side of the wheelchair frame 110, a pair of through holes 211 are formed in the pedal support cross rod 210, a pair of pedal support vertical rods 220 respectively penetrate through the pair of through holes 211, and the pair of pedal support vertical rods 220 can slide back and forth in the through holes 211. The left and right sides of the front end of the footboard 120 are hinged to the front ends of a pair of footboard support vertical bars 220 through the rotating shaft 121, so that the footboard 120 can be turned around the rotating shaft 121. A stopper rod 230 is connected to the rear ends of the rods of the pair of pedal support shafts 220. An arc-shaped portion 122 is provided at the rear end of the footboard 120 to be turned up.

Referring to fig. 4 to 9, when the pedal 120 is in use, the pedal 120 is seated on the pair of vertical pedal support rods 220, so that the force applied to the pedal 120 is transmitted to the pedal support rail 210 through the pair of vertical pedal support rods 220, and then transmitted to the wheelchair frame 110 through the frame rail 111. When the pedals 120 need to be stored in the wheelchair frame 110, the pair of pedal support vertical rods 220 can be pushed backwards, and when the arc-shaped part 122 at the rear end of the pedals 120 touches the framework cross rod 111, the framework cross rod 111 can smoothly enter the bottom of the pedals 120 through the arc-shaped part 122, so that the pedals 120 are pushed to be turned upwards. When the pair of vertical pedal support rods 220 are retracted to the final position, the entire pedal 120 is vertically accommodated in the wheelchair frame 100.
