Abstract
A foldable treadmill includes a base for running or walking, a frame set pivotally connected with the base, and a folding mechanism for folding the frame set. The folding mechanism has a control assembly and a sliding rod connected with the frame set and capable of being locked or released by the control assembly. When the control assembly locks the sliding rod at a first position, the frame set cannot be rotated, and when the control assembly releases the sliding rod, the frame set can be rotated to a storage position thus pulling the sliding rod to a second position.
Claims9
A foldable treadmill, comprising:
- a base for running or walking;
- a frame set pivotally connected with the base;
- and
- a first folding mechanism, comprising:
- a control assembly;
- and
- a sliding rod with an end being connected with the frame set;
- wherein the sliding rod is capable of being locked or released by the control assembly;
- when the control assembly locks the sliding rod at a first position, the frame set cannot be rotated, and when the control assembly releases the sliding rod, the frame set can be rotated to a storage configuration whereby the sliding rod is pulled to a second position;
- and
- wherein the control assembly comprises:
- a tube, having a side wall with an opening, a portion of the sliding rod being arranged within the tube;
- a fixing member, passing through the opening of the tube and contacting with the sliding rod;
- and
- at least a torsion spring having a first end and a second end, the sliding rod passing through the torsion spring, wherein the first end of the torsion spring connects with the inner wall of the tube, and the second end of the torsion spring connects with the fixing member, so that the torsion spring provides a torsion to press the fixing member against the sliding rod and thus lock the sliding rod.

A foldable treadmill, comprising:
- a base for running or walking;
- a frame set comprising a first post and a second post pivotally connected with the base, respectively;
- a first folding mechanism, comprising a first control assembly and a first sliding rod with an end being connected with the frame set, wherein the first sliding rod is capable of being locked or released by the first control assembly;
- and
- a second folding mechanism, comprising a second control assembly and a second sliding rod with an end being connected with the frame set, wherein the second sliding rod is capable of being locked or released by the second control assembly;
- wherein the frame set cannot be rotated when the first control assembly locks the first sliding rod at a first position and the second control assembly locks the second sliding rod at a first position, and wherein the frame set can be rotated when the first control assembly releases the first sliding rod and the second control assembly releases the second sliding rod, such that the frame set is rotated to a storage configuration corresponding to movement of the first sliding rod and the second sliding rod to a second position;
- and
- wherein the first control assembly comprises:
- a first tube, having a side wall with an opening, a portion of the first sliding rod being arranged within the first tube;
- a first fixing member, passing through the opening of the first tube and contacting with the first sliding rod;
- and
- at least a first torsion spring having a first end and a second end, the first sliding rod passing through the first torsion spring, wherein the first end of the first torsion spring connects with the inner wall of the first tube, and the second end of the first torsion spring connects with the first fixing member, so that the first torsion spring provides a torsion to press the first fixing member against the first sliding rod and thus lock the first sliding rod.
