Actuator for controlling inclination of treadmill and inclination control device of treadmill
First Claim
1. An actuator for controlling the inclination of the track part of a treadmill comprising:
- a motor;
a pinion rotatably driven by the motor;
a belt formed to transmit the driving force from the pinion;
a pair of driving pulleys engaging with the belt so as to receive the driving force from the pinion;
a pair of screw rod combined with each of the driving pulley for rotating together with each of the driving pulley; and
a pair of housings having female thread for engaging with each of the screw rod;
wherein a pair of screw rods are simultaneously extruded from or simultaneously inserted into each of the housing by the same length.

Abstract
The present invention provides an inclination control device of a treadmill comprising: a pair of support members pivotally connected with at least one first hinge at the track part for extending from the track part to the ground; a pair of housings having a housing hinge respectively for being pivotally connected with each of the second hinge at the support members, and having female thread; a pair of screw rod engaging respectively with the female thread of each of the housing so as to be extruded from or inserted into by relative rotation therebetween; a pair of driving pulleys combined with each of the screw rod for rotating together with the screw rod; a belt engaging with the driving pulleys; a pinion engaging with the belt for transmitting a driving force via the belt to the driving pulleys; a motor for letting pinion rotate; and a bracket for rotatably fixing the pinion and the driving pulleys, and having a pair of bracket hinges on its both sides to be pivotally combined with each of the third hinges of the track part, whereby the first hinge, the second hinge and the third hinge form a three-linked structure so as to stably support the impact and/or load from a user'"'"'s running in addition to enhance durability and to save the manufacture cost.

5. An inclination control device for a treadmill having at least one track part comprising:
-
at least one support member pivotally connected with at least one first hinge at the track part for extending from the track part to the ground; and
at least one extendable rod pivotally connected with at least one second hinge which moves together with the support member, and pivotally connected with at least one third hinge of the track part which is located apart from the first hinge at the track part;
wherein, the inclination of the track part is controlled by the extension or the contraction of the extendable rod. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
