Stairs, mountain stairs, etc. are composed of steps. According to the specification of the unified civil architecture design standard GB 50352-2019 6.7.1: the height of the steps of the indoor and outdoor steps of the public building is not more than 0.15m, namely the height of each step is not more than 15cm, and in reality, the height of most steps is about 14cm, so that people with leg muscle strength grades of 4-and below can not get up easily; even if people with normal leg muscle strength climb higher buildings or mountains, the people can be tired in the later period and have a strong effort.

According to the report that when climbing stairs, the knee joint is bent by about 30 degrees when one step is stepped on, and the pressure of the patella to the posterior condyle is about 2 megapascals; when two steps are stepped on, the knee bending angle of the knee joint is about 70 degrees, and the pressure of the patella to the posterior condyle is about 4 megapascals, so that the higher the steps are, the higher the legs of people are lifted, so that the larger the knee bending angle of the people is, and the larger the stress of the knee joint is.

The research shows that the knee joint of the human body is bent for 30 degrees, the pressure born by the knee joint is equal to the gravity, the knee joint is bent for 60 degrees, the pressure born by the knee joint is 4 times of the weight, the knee joint is bent for 90 degrees, and the pressure born by the knee joint is 6 times of the weight; and the pressure in the knee joint is about half of the weight when the patient walks in the joint, the pressure in the knee joint is increased when the patient walks up to stairs and is 2.2-3.3 times of the weight of the human body, and the pressure in the knee can reach 7.8 times of the weight in deep knee bending movement. In summary, it is further explained that the greater the knee bending angle, the greater will be the force experienced by the knee joint.

For people with pathological changes of the knee joint, the patient is easy to aggravate when the patient climbs the step (such as climbing stairs), and the higher the step is, the larger the stress of the knee joint is, and the patient is easy to aggravate the knee joint.

The existing tools for assisting people to go up and down stairs or go up and down mountains are walking sticks, alpenstocks, elevators and electric pedal type escalators, and wheelchairs (such as an electric wheelchair with a stair climbing function-CN 202222382607.3) for climbing steps also appear in recent years, so that convenience is provided for people with inconvenient legs and feet.

Example 1

A crutch capable of foot-padding, as shown in fig. 1-2:

comprises a crutch body and a cushion body, wherein the lower end of the crutch body 2 is connected with the upper part of the cushion body, and the upper end of the crutch body is connected with a handle. Specifically: the upper part of the pad body is provided with a square pedal 1, so that the upper end of the pad body forms a square supporting surface, the lower part of the pedal is provided with four supporting legs 11, and if the pedal and the supporting legs are made of metal, the pedal and the supporting legs can be welded and fixed. The distance from the crutch body to one side of the supporting surface of the cushion body is 5-20cm, the distance from the crutch body to the supporting surface of the cushion body is denoted as a side a, the length of the side a is 10-30cm, the pedal for adults is arranged to be bigger, and the pedal for children is arranged to be smaller according to the requirements. For example: the distance from the crutch body to the side a is set to be 12cm for adults, and the length of the side a is set to be 20cm; the distance from the crutch body to the side a is 10cm, and the length of the side a is 15cm, so that the surface on which the user can tread on the pedal is relatively close to the size of the shoes, one foot is treaded on the pedal, the contact area between the shoes and the pedal is relatively large, and the user can stand on the cushion relatively stably. As the steps of the stairs or mountain stairs are generally about 14cm in height, the height of the cushion body is half of the height of the steps, namely, the height of the cushion body is 7cm, so that most of requirements can be met.

Further, the protection pad 7 is arranged in a sleeve shape with an upward opening, and the lower part of each supporting leg is sleeved with one protection pad to protect the supporting leg, so that the supporting leg is not easy to wear.

The opposite side of the upper side a of the pedal is side b, and the lower end of the crutch body is positioned between the middle of the upper end of the pad body and the side b. The position adjusting mechanism 3 comprises a strip-shaped through groove 30 which penetrates through the pad pedal up and down and a connecting piece for connecting the crutch body and the pad pedal. The strip-shaped through groove extends from the middle position of the pedal to the direction of the side b, and the connecting piece comprises a bolt 32 and a nut 31. The bolt is preferably an eye bolt or a bolt with a screwing handle, so that the screwing handle is convenient to screw by hands. The nut is fixed with the lower end of the crutch body, the bolt is connected with the nut from bottom to top through the strip-shaped through groove, a gasket 33 is arranged between the nut and the pedal, and a gasket 33 is also arranged between the head of the bolt and the pedal. The nut is unscrewed, so that the slide bolt and the movable crutch body can be slid at corresponding positions (the treads with different widths are adjusted, and the use of different users is facilitated), and then the nut is screwed down, so that the crutch body and the cushion body are fixed together. When the crutch is not used for climbing up and down steps, the crutch body is moved to the middle of the pedal, so that the pedal is uniformly stressed and is not easy to incline when the crutch is used for walking on the ground.

The method of using the present embodiment will be specifically described with the right foot stepping on the pedal:

1. the step is stepped upwards, and the steps from bottom to top are the first step, the second step and the nth step. Holding a crutch (handle) by a right hand, placing the pad under a first step (in front of the right foot), then boarding the pad by the right foot, then boarding the first step by the left foot, then moving the right foot upward (the right foot can be lifted up by the hand by the aid of the crutch pad, the force of lifting the leg by the right foot upward is saved), and placing the pad on the first step, then boarding the pad by the right foot again, then boarding the second step by the left foot, and repeating the above method to board a third step and the steps above. As the general step height is 14cm, the pad height can be set to 7cm, so that the step height of each climbing is reduced by half, the leg strength requirement can be basically reduced by half, the knee bending angle is greatly reduced, the stress on the knee joint is greatly reduced by combining, the abrasion on the knee joint is greatly reduced, and the knee joint is protected to a certain extent.

2. The steps are downwards moved, and the steps are the first step, the second step and the nth step from top to bottom. The crutch is held by the right hand, the cushion is placed on the second step (in front of the right foot), then the cushion is stepped on by the right foot, then the second step is stepped on by the left foot, then the right foot is slightly moved upwards, and the cushion is placed on the third step, then the right foot is stepped on the cushion again, then the third step is stepped on by the left foot, and the method is repeated to walk downwards to the fourth step and the steps below. If the height of the step is 14cm and the height of the cushion body is 7cm, the step similar to the height of 14cm is divided into two steps with the height of 7cm to walk, on one hand, the knee bending angle of the temporarily non-moving foot is reduced by nearly half, and the stress of the knee joint is reduced; on the other hand, the downward moving distance of the foot is reduced by half, so that the downward impact force is reduced greatly, the impact force on the knee joint is reduced, the abrasion is reduced, and the knee joint is protected to a certain extent.

Note that: if the crutch is used on the left foot, the nut is unscrewed, the cushion body is rotated 180, and then the nut is screwed.

The step on (or under) the crutch has the advantages that although one step needs to be stepped on (or stepped down) and the time is increased, the crutch has the advantages for special people (people with poor leg strength or damaged knee joints), and the special people do not need to pursue rapidness. As a general example: the baby carriage is moved on the baby carriage for a time which is more than 100 jin of things, so that people with insufficient waist strength are hard to use, and the waist muscle is easy to damage; if the vehicle is moved on for 4 times, the vehicle can be moved 25 jin each time, so that the vehicle is easy and the lumbar muscle injury is not easy to cause. The same is true for 100 jin of goods moving vehicles.
