Problems solved by technology

[0003] None of the above contact forms can achieve stable support alone, and multiple sets of support structures are required to cooperate to achieve support. If the distance between each support point is relatively close, it will easily cause the center of gravity to be unstable and the range of motion will be limited; and if the distance between each support point If it is far away, it will easily lead to an increase in the size of the stair climbing device and a decrease in convenience

Embodiment 1

[0035] In this embodiment, the structure and working state of the stepped support mechanism are mainly introduced.

[0036] Such as figure 1 As shown, the stepped support mechanism includes two supporting feet, and the two supporting feet both contain telescopic devices 2 3a, that is, both can be stretched.

[0037] When the stepped support mechanism changes from the suspended state to contact with the stairs and form a support: first, extend the telescopic support arm 2 downwards, so that the support foot 3 on the right side of the figure first comes into contact with a step surface F2, and then Align the left supporting foot 3 with the next step surface F1, and then use the telescopic device 2 3a to telescopically adjust the left supporting foot 3 until the two supporting feet 3 respectively form stable surface contact with the two step surfaces; Thus, a stepped support spanning two steps (F1+F2) is realized. Since the two supporting legs can be stretched, the overall supp...

Embodiment 2

[0046] This embodiment mainly introduces the practical application of the stepped support mechanism in the step climbing device.

[0047] The step-climbing device includes several stepped support mechanisms. During operation, each stepped support mechanism is alternately in a supporting state or in a suspended state, and the supporting position is replaced, thereby completing the action of going up / down steps.

[0048] Wherein, each stepped support mechanism is respectively connected with the main body 1 of the stair climbing device, and can alternately move forward and backward along the direction of travel of the step climbing device;

[0049] The following is a specific case: firstly, the stepped support mechanism is divided into two groups (hereinafter referred to as La and Lb), which are respectively connected to the main body 1 of the stair climbing device.

[0050] From image 3From the angle of view, La is a wide stepped support mechanism located in the middle of the ...

Abstract

A stepped supporting mechanism used for a step climbing device is characterized in that: the stepped supporting mechanism includes a telescopic supporting arm (2) and multiple support legs (3); and astepped surface support crossing two or more steps is formed by the stepped supporting mechanism, the stability of the support is improved, thereby simplifying a structure of the step climbing device.

Description

technical field [0001] The invention relates to a stepped support mechanism for a step-climbing device. The stepped support mechanism forms a step surface support spanning two or more steps, improves the stability of the support, and simplifies the structure of the step-climbing device. Technical field of stair installation. Background technique [0002] In the process of going up / down stairs in the existing step-type stair-climbing device, the support forms in contact with the stairs are usually point contact, line contact or plane contact. [0003] None of the above contact forms can achieve stable support alone, and multiple sets of support structures are required to cooperate to achieve support. If the distance between each support point is relatively close, it will easily cause the center of gravity to be unstable and the range of motion will be limited; and if the distance between each support point If it is far away, it will easily lead to an increase in the size of ...
