Treadmill deck locking mechanism
View Patent ↗The present invention relates to a locking mechanism for use with exercise treadmills capable of being selectively configured in an operating configuration or a storage configuration. The locking mechanism may utilize various configurations of engagement devices and/or locking members to allow a user to selectively lock a treadmill frame in a fixed position relative to a base frame.
1. A treadmill comprising:
a base frame;
a treadmill frame including a first end portion and a second end portion distal the first end portion;
the treadmill frame moveably connected to the base frame proximate the first end portion of the treadmill frame, the treadmill frame configurable between an operating configuration and a storage configuration;
a belt operatively associated with the treadmill frame;
a locking mechanism comprising:
an engagement member positioned proximate the first end portion of the treadmill frame;
an actuator operatively associated with the engagement member, the actuator positioned distal from the engagement member and proximate the second end portion of the treadmill frame; and
the actuator selectively actuated to operatively engage and disengage the engagement member with the base frame;
operative engagement of the engagement member with the base frame prevents the treadmill frame from being moved relative to the base frame between the operating configuration and the storage configuration; and
operative disengagement of the engagement member from the base frame allows the treadmill frame to be moved relative to the base frame between the operating configuration and the storage configuration.
2. The treadmill of claim 1 , wherein the engagement member and the actuator are supported by the treadmill frame.
3. The treadmill of claim 2 , wherein the base frame includes at least one aperture, and at least a portion of the engagement member is received with the at least one aperture to engage the engagement member with the base frame.
4. The treadmill of claim 2 , wherein the base frame includes a first aperture and a second aperture, at least a portion of the engagement member is received with the first aperture to engage the engagement member with the base frame when the treadmill is positioned in the operating configuration, and at least a portion of the engagement member is received in the second aperture to engage the engagement member with the base frame when the treadmill is positioned in the storage configuration.
5. The treadmill of claim 4 , wherein the first aperture comprises a slot.
6. The treadmill of claim 4 , wherein the base frame includes a bracket, and the bracket defines the first aperture and the second aperture.
7. The treadmill of claim 1 , wherein the engagement member comprises a pin.
8. The treadmill of claim 1 , wherein the locking mechanism further comprises a bias member that biases the engagement member into operative engagement with the base frame.
9. The treadmill of claim 1 , wherein the actuator comprises a handle, and selective rotation of the handle operatively disengages the engagement member from the base frame.
10. The treadmill of claim 1 , further comprising a lift assistance mechanism operably coupled to the treadmill frame and the base frame.
11. The treadmill of claim 10 , wherein the lift assistance mechanism comprises at least one lift cylinder.
12. The treadmill of claim 11 , wherein the at least one lift cylinder contains pressurized air.
13. The treadmill of claim 11 , wherein the at least one lift cylinder defines an extended length when the treadmill frame is in a storage position, and the at least one lift cylinder defines a compressed length when the treadmill frame is in a operating position.
14. The treadmill of claim 1 , wherein the treadmill frame is moveably connected to the base frame by pivotally connecting the treadmill frame to the base frame.
15. The treadmill of claim 14 , wherein the treadmill frame is configured between the operating position and the storage position by pivoting the treadmill frame relative to the base frame.
16. A treadmill comprising:
a base frame;
a treadmill frame moveably connected to the base frame, the treadmill frame configurable between an operating configuration and a storage configuration;
a belt operatively associated with the treadmill frame;
a locking mechanism comprising:
an engagement member;
an actuator operatively associated with the engagement member via a cable, the actuator positioned distal from the engagement member; and
the actuator selectively actuated to operatively engage and disengage the engagement member with the base frame;
operative engagement of the engagement member with the base frame prevents the treadmill frame from being moved relative to the base frame between the operating configuration and the storage configuration; and
operative disengagement of the engagement member from the base frame allows the treadmill frame to be moved relative to the base frame between the operating configuration and the storage configuration.
