Deadweight driving dry skate

Abstract

The invention discloses a self-weight roller skate; a shaft seat is fixed and arranged below the rear end of a fixed main board; the upper end of the shaft seat is provided with an auxiliary shaft; the auxiliary shaft is provided with a one-way gear and a variable speed gear; the lower end of the shaft seat is provided with a main shaft; the middle of the main shaft is provided with a main shaft gear; both sides of the main shaft are provided with rear wheels; the variable speed gear is engaged with the main shaft; a power rack is arranged between a pedal and the one-way gear; a positioning wheel is fixed and arranged on one side of the shaft seat. The invention has the advantages that each step of the user on the pedal produces pressure which is more than the weight of the body; the powerrack drives the one-way gear under the human body weight pressure; the positioning wheel prevents the power rack from sliding externally, so the power rack can be tightly adhered to the gear, and theroller stake can easily move forwards, and does not step back when climbing a slope or running on flat roads.

Description

technical field [0001] The invention relates to a roller skate, in particular to a self-weight driven roller skate. Background technique [0002] Existing roller skates only have a few runners installed under the soles. When exercising, people push the ground obliquely backward and use the forward reaction force to move forward. The utilization rate of the human body's own gravity is very low, so it is more laborious. Now the Chinese patent No. ZL200320111268.X discloses a self-weight-driven roller skate. Its structure is that the front caster is fixed on the front end of the bottom surface of the pedal, the rear caster is fixed to the rear caster shaft, one end of the movable support is hinged to the rear caster shaft, and the other end is connected to the rear caster shaft. The pedals are hinged, the movable bracket and the pedals are fixed by springs, the rear caster shaft is fixed to the one-way transmission wheel and the rack, the gear meshing with the rack is fixed to ...

[0002] Existing roller skates only have a few runners installed under the soles. When exercising, people push the ground obliquely backward and use the forward reaction force to move forward. The utilization rate of the human body's own gravity is very low, so it is more laborious. Now the Chinese patent No. ZL200320111268.X discloses a self-weight-driven roller skate. Its structure is that the front caster is fixed on the front end of the bottom surface of the pedal, the rear caster is fixed to the rear caster shaft, one end of the movable support is hinged to the rear caster shaft, and the other end is connected to the rear caster shaft. The pedals are hinged, the movable bracket and the pedals are fixed by springs, the rear caster shaft is fixed to the one-way transmission wheel and the rack, the gear meshing with the rack is fixed to the pedals through bearings, and the rear large transmission is fixed coaxially with the gears The front small transmission wheel meshed with the rear large transmission wheel is fixed by the bearing and the pedal, and the front large transmission wheel is fixed coaxially with the front small transmission wheel, and the front large transmission wheel meshes with the one-way transmission wheel, which is complicated structure, and it is very difficult to implement
