Example 2 this example differs from example 1 in that: the second leg supporting rod of the shank supporting mechanism is U-shaped steel, a bottom plate of the U-shaped steel is used as a supporting surface attached to the shank of a user, and a second leg fixing piece used for fixing the shank is fixedly arranged on the supporting surface.
Example 3 this example differs from example 2 in that: the second leg mount is a strap or a notched annular collar.
Example 4 this example differs from example 1 in that: the first leg mount is a strap or a notched annular collar.
Example 5 this example differs from example 2 in that: the second leg mount is a strap or a notched annular collar.
Example 6 this example differs from example 1 in that: the pedal is of a U-shaped structure, and the groove in the middle of the U-shaped structure is used for placing a foot; the two walls of the groove are respectively provided with a connecting piece, the lower end of the connecting piece is hinged with the wall of the groove, the connecting piece is axially provided with a plurality of positioning holes, corresponding positioning holes are selected according to the requirements of users, and then the connecting piece is hinged with the lower end of the second leg supporting rod by using positioning pins, so that the two connecting pieces are respectively positioned at the two sides of the shank.
Example 7 in this example: the upper connecting rod and the lower connecting rod are both U-shaped square tubes.
The working process is as follows: when a user is in a standing state, the hand-holding mechanism is in a vertical state, and the auxiliary rising mechanism is also in a vertical state;
when the user sits down, the board of standing up down, oppress the fifth connecting rod and make and store the potential energy rather than the spring compression that links to each other and make preparation for standing up, the fourth connecting rod with the linkage of fifth connecting rod also rotates simultaneously, the third connecting rod can make the handrail also rotate along with the rotation of fourth connecting rod, when the spring compression stops, the handrail can reach corresponding position and make the handrail be the level, the part can slide backward in the spout on the gas spring of in-process, reach the last section, the gas spring compresses, reach the balance at last, then can form a triangle-shaped and play the supporting role. Handrail: the first end of the fifth connecting rod moves downwards under the pressure of the rising plate so as to drive the second end of the fifth connecting rod to rise, so that the fourth connecting rod hinged with the fifth connecting rod rises, the third connecting rod rises, the lower end of the handrail not only rises in the vertical direction, but also moves in the horizontal direction, and the handrail is changed into a vertical handrail state from a horizontal storage state.
When rising, the hand supports the hand-held mechanism, and when rising, the fourth connecting rod, the third connecting rod and the connecting rod can be driven to rotate and the spring releases elastic potential energy to drive the rising plate to rotate upwards to assist in rising.
When in motion: due to the sliding groove structure, the upper end of the gas spring can slightly slide in the groove, and the normal movement of the gas spring cannot be influenced
When the disassembly is carried out: u type buckle is taken off in the conical trip groove of spout, is about to the air spring and dismantles, and rethread three-dimensional universal joint is from overturning down to be about to the shank part and to incorporate thigh lower extreme axial and accomodate the groove, detaches simultaneously the buckle subassembly between connecting rod and the lower connecting rod, then accomodates the connecting rod down below the upper junction pole through the hinge, easily deposits.
As shown in fig. 1, the gas spring is in a compressed state, and the gas spring in the chute is pushed upwards, so that the gas spring cannot fall from the opening of the chute
In the folded state one:
after the gas spring is taken out through the sliding chute, the front end of the second leg supporting rod can be folded into the space at the rear end of the lower connecting rod to complete the first folding;
and a second folded state: after the folding state I is finished, the hanging buckle is taken down, and the rear end of the thigh and the shank are folded and placed at the front end of the thigh to finish folding; the overall mechanism volume after folding was calculated to be 727.04mm before folding and 240mm after folding, with a nearly seventy percent reduction in length and a nearly fifty percent reduction in volume.
The embodiments described in this specification are merely illustrative of implementations of the inventive concepts, and the scope of the invention should not be considered limited to the specific forms set forth in the embodiments, but rather the scope of the invention includes equivalent technical means that can be conceived by those skilled in the art based on the inventive concepts.
