The present invention belongs to the field of treadmills, and specifically pertains to a foot-operated unlocking treadmill.
Treadmills are common fitness equipment in homes and gymnasiums, and are one of the simplest types of home fitness equipment today, making it the best choice for home fitness equipment.
Existing treadmills usually include a treadmill stand and upright posts. The treadmill stand serves as a running area for users to run and exercise on, while the upright posts are usually arranged upright, and a control panel with a suitable height is provided on the upright posts, allowing users to control speed, slope and the like on the control panel conveniently.
In addition, to achieve convenient use of the treadmill, usually the upright posts can be disassembled or turned over relative to the treadmill stand. For example, the upright posts are hinged to the treadmill stand and loosened by operating a screw with a knob. In a loosened state, the upright posts rotate relative to the treadmill stand to flip upward for use and flip downward for folding; and after such turnover is completed, the screw is operated by the knob to achieve fastening so as to fix the upright posts and the treadmill stand and ensure the stability of use.
The above treadmills have problems that the knob needs to be turned multiple times by hand to loosen or tighten, which is a complex operation and the knob is easy to loosen if not tightened. Moreover, the knob is located at an intersegment of the upright posts and the treadmill stand, which is in a low position, so users need to squat or bend down for operation, resulting in inconvenient operation.
In view of the deficiencies of the prior art, an object of the present invention is to provide a foot-operated unlocking treadmill, in which an unlocking member is stepped to drive a first locking member to move by a connecting rope to conveniently unlock upright posts and a running platform, so that folding is more convenient.
In order to achieve the above object, the present invention provides the following technical solutions: the treadmill includes: a running platform provided with a deployed position and a stowed position; and upright posts rotatably mounted on the running platform, where the upright posts are rotated to the deployed position so that the running platform and the upright posts are in a relatively deployed state, and the upright posts are rotated to the stowed position so that the running platform and the upright posts are in a relatively stowed state; where the running platform and the upright posts are respectively provided with a first locking member and a second locking member thereon, the first locking member is movably arranged, and the second locking member is fixedly arranged; and an unlocking member, where the first locking member is drivingly movable by the unlocking member so that the first locking member and the second locking member are locked or unlocked; the second locking member is provided with a first locking position and a second locking position thereon, when the upright posts are in the deployed position, the first locking member is snapped into the first locking position to lock the upright posts, and when the upright posts are in the stowed position, the first locking member is snapped into the second locking position to lock the upright posts; and the unlocking member is a foot switch which is movably provided in a pivoting or reciprocating position, and the unlocking member acts to drive the first locking member to retract or displace, so that the first locking member is detached from the first locking position or the second locking position.
By adopting the above-mentioned technical solutions, 1. when the upright posts need to be in the deployed position to cause the treadmill to be in an L-shape for use, the upright posts are fixed to the running platform under the action of the first locking member to ensure stability in the deployed state; 2. when the upright posts need to be flipped from the deployed position to the stowed position to cause the treadmill as a whole to be in a straight line shape, the connecting rope is pulled by stepping on the unlocking member and the pulled connecting rope drives the connected first locking member to move to release the fixed connection between the upright posts and the running platform, so that the upright posts can be flipped to switch from the deployed position to the stowed position, and the upright posts and the running platform can be unlocked only by stepping, which further facilitates operation; and 3. when the upright posts need to be flipped from the stowed position to the deployed position to cause the overall treadmill as a whole to be in the L-shape, the connecting rope is pulled by stepping on the unlocking member and the pulled connecting rope drives the connected first locking member to move so that the first locking member does not interfere with circumferential rotation of the upright posts, so that the upright posts can be flipped to switch from the stowed position to the deployed position; and after the upright posts are in place, the unlocking member is released so that the first locking member can be reset under the action of the resetting member to achieve the fixed connection between the upright posts and the running platform.

Specifically, the treadmill further includes:
Therefore, 1. when the upright posts 2 need to be in the deployed position 13 to cause the treadmill to be in an L-shape for use, the upright posts 2 are fixed to the running platform 1 under the action of the first locking member 3 to ensure stability in the deployed state; 2. when the upright posts 2 need to be flipped from the deployed position 13 to the stowed position 14 to cause the treadmill as a whole to be in a straight line shape, the connecting rope 5 is pulled by stepping on the unlocking member 4 (the stepping is an unlocking action) and the pulled connecting rope 5 drives the connected first locking member 3 to move to release the fixed connection between the upright posts 2 and the running platform 1, so that the upright posts 2 can be flipped to switch from the deployed position 13 to the stowed position 14, and the upright posts 2 and the running platform 1 can be unlocked only by stepping, which further facilitates operation; and 3. when the upright posts 2 need to be flipped from the stowed position 14 to the deployed position 13 to cause the overall treadmill as a whole to be in the L-shape, the connecting rope 5 is pulled by stepping on the unlocking member 4 and the pulled connecting rope 5 drives the connected first locking member 3 to move so that the first locking member 3 does not interfere with circumferential rotation of the upright posts 2, so that the upright posts 2 can be flipped to switch from the stowed position 14 to the deployed position 13; and after the upright posts 2 are in place, the unlocking member 4 is released so that the first locking member 3 can be reset under the action of the resetting member to achieve the fixed connection between the upright posts 2 and the running platform 1.
The unlocking member 4 in the present embodiment is rotatably arranged on the running platform 1, the unlocking member 4 is provided thereon with a treading portion 41 inclined toward the upper left, and the treading portion 41 is stepped to drive the unlocking member 4 to rotate; and the first locking member 3 is slidably arranged on the running platform 1 in a front-rear direction, and the first locking member 3 is pulled by the connecting rope 5 to move in a direction away from the upright posts 2 to slide so as to release the fixed connection between the upright posts 2 and the running platform 1.
This enables the unlocking member 4 to rotate by stepping on the treading portion 41 toward the lower left, so that the first locking member 3 is slidably driven in the direction away from the upright posts 2 by the connecting rope 5, so that the first locking member 3 slidably releases the fixed connection between the upright posts 2 and the running platform 1 to realize flipping adjustment of the upright posts 2. Correspondingly, the resetting member drives the first locking member 3 to slidably move in a direction close to the upright posts 2 and drives the unlocking member 4 to rotate so that the treading portion 41 rotates toward the upper right.
Specifically, the resetting member in the present embodiment includes a first resetting member 61 located between the unlocking member 4 and the running platform 1, and the first resetting member 61 is configured to rotationally reset the treading portion 41. More specifically, the first resetting member 61 in the present embodiment is a tension spring, so that one end of the tension spring is hooked to the running platform 1, and the other end is hooked to the unlocking member 4.
