Problems solved by technology

The pedals and matching boards in this patent are designed for the entire surface and cannot be folded and stretched. When the car is not in use, the pedals are horizontally arranged at both ends of the car, which increases the overall width of the car, resulting in two adjacent Cars need to reserve a lot of space when parking, resulting in a waste of parking spaces
Moreover, after increasing the overall width of the car, the pedals are likely to cause scratches to adjacent parked cars, and the pedals are also easily damaged by adjacent parked cars.
There is also a type of pedal, which needs to be manually reduced in size. Not only does the user need to bend over to operate, but also only rely on the other hand to support the vehicle. When the vehicle is supported by one hand, the stability of the vehicle is poor. easy to dump

Embodiment 1

[0028] Embodiment 1: as figure 1 , 2 As shown, a foldable pedal device for the disabled includes a central axis 18, a crank 14 sprocket 15, a pedal body 1 connected to a crank end and a main shaft tube 2 fixedly connected to the crank end, the main shaft tube 2 is rotationally connected with the pedal body 1. The end of the other crank is connected with counterweight 16, and the weight of counterweight is greater than pedal body. The sprocket wheel 15 outer side is provided with sprocket cover 17, is fixed with first magnet 19 on the sprocket cover, and first magnet 19 is positioned at crank sprocket top and is close to the side of front wheel, is provided with on the crank that links to each other with pedal body and The first magnet magnetically attracts the second magnet 20 . The position symmetrical with the center of the first magnet is provided with a third magnet 21, and the crank connected to the counterweight is provided with a fourth magnet 22 which is attracted t...

Embodiment 2

[0030] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 8 As shown, the outer surface of the main shaft tube is covered with a sleeve body 13, and the outer surface of the main shaft tube and the sleeve body are connected by bearings. There are two pedal bodies, and both sides of the sleeve body are provided with pedal bodies. The bodies are connected by a rotating shaft 9, the rotating shaft is arranged vertically to the axis of the main shaft tube, the pedal body is rotationally connected with the sleeve body through the rotating shaft, and the upper and lower edges of the sleeve body near one end of the telescopic portion are provided with arc surfaces. Fixing holes 11 are arranged on the upper and lower ends of the casing, and the diameter of the fixing holes 11 is greater than or equal to the outer diameter of the fixing rod. Such as Figure 7 As shown, a positioning hole 10 is coaxially arra...

Abstract

The invention relates to a pedal, in particular to a foldable pedal device for a disabled person. The foldable pedal device for the disabled person comprises a center shaft, a crank sprocket, pedal bodies connected with the end part of one crank and a main shaft tube fixedly connected with the end part of the crank, wherein the main shaft tube is rotationally connected with the pedal body; the end part of another crank is connected with a balancing weight; the weight of the balancing weight is larger than that of the pedal bodies; a stretching part is arranged on the side surface of each pedal body, and slide bars are arranged at two ends of each stretching part; slide holes glidingly connected with the slide bars are formed in the pedal bodies; fixing bars are arranged in the middles of the stretching parts; threaded holes in threaded connection with the fixing bars are formed in the main shaft tube. The foldable pedal device for the disabled person has the befits that stepping assistance can be provided for the disabled user, circling of pedals is facilitated, the pedal device can stretch while not required to be used, and horizontal occupied space is reduced and the like.

Description

technical field [0001] The invention relates to a pedal, in particular to a foldable pedal device for disabled persons. Background technique [0002] Existing bicycles or spare pedals adopt integral design, are fixed on the crank connecting rod through the main shaft, pedals are used at both ends, and the weight of the two pedals is the same. When people with disabilities in legs or feet use this type of bicycle, they can only step on the pedals on one side. When the pedals go around half a circle near the rear wheel side, it is difficult for the pedals to rotate to the highest point. It is inconvenient for the disabled to pedal. When the car does not need to be used, the pedals are horizontally arranged at both ends of the car, which increases the overall width of the car, causing two adjacent cars to reserve a large space when parking, resulting in a waste of parking spaces. And after increasing the overall width of the car, the pedals are likely to cause scratches to th...
