Treadmill including a deck locking mechanism
A treadmill may include a lock mechanism operative to selectively lock a deck assembly in one or more positions relative to a base frame. The lock mechanism may include an engagement member that locks the deck assembly in an operating position while allowing incline adjustment of the deck assembly relative to the frame during use of the treadmill.
1. A treadmill comprising:
a frame;
a deck assembly including a front end portion pivotally connected to the frame, the deck assembly positionable in an operating position and a storage position;
a first tube connected to one of the frame or the deck assembly, the first tube defining an aperture and a slot spaced apart from each other along a length of the first tube, wherein the slot extends lengthwise along the length of the first tube;
a second tube connected to the other of the frame or the deck assembly and slidably connected to the first tube; and
a lock mechanism operative to lock the deck assembly in the operating position and the storage position, the lock mechanism comprising:
a pin operatively connected to the second tube and engageable with the aperture and the slot of the first tube; wherein:
engagement of the pin with the aperture locks the deck assembly in the storage position; and
engagement of the pin with the slot locks the deck assembly in the operating position while allowing incline adjustment of the front end portion of the deck assembly relative to the frame during operation of the treadmill, wherein the slot is dimensioned to receive at least a portion of the pin and allow the pin to slide within the slot.
2. The treadmill of claim 1 , wherein engagement of the pin with the aperture substantially prevents the deck assembly from being moved relative to the frame.
3. The treadmill of claim 1 , wherein disengagement of the pin from the aperture and the slot allows the deck assembly to be moved relative to the frame between the operating position and the storage position.
4. The treadmill of claim 1 , wherein the aperture is dimensioned to receive at least a portion of the pin and substantially prevent the deck assembly from being moved relative to the frame.
5. The treadmill of claim 1 , wherein:
the first tube includes a first end portion pivotally connected to the one of the frame or the deck assembly and a second end portion distal to the first portion; and
the slot is located between the aperture and the first end portion of the first tube.
6. The treadmill of claim 1 , wherein:
the second tube includes a first end portion pivotally connected to the other of the frame or the deck assembly and a second end portion distal to the first portion; and
the pin is connected to the second tube proximate to the second end portion of the second tube.
7. The treadmill of claim 1 , wherein the pin is slidable between a first position in which the pin is engaged with the aperture or the slot and a second position in which the pin is disengaged from the aperture and the slot.
8. The treadmill of claim 7 , further comprising a spring that biases the pin towards the first position.
9. The treadmill of claim 1 , further comprising a handle positioned remote from the pin and operatively associated with the pin to disengage the pin from the aperture and the slot.
10. The treadmill of claim 9 , wherein the handle is pivotally connected to the deck assembly such that pivotal motion of the handle relative to the deck assembly disengages the pin from the aperture or the slot.
11. The treadmill of claim 9 , wherein:
the deck assembly has a rear end portion distal to the front end portion; and
the handle is pivotally connected to the rear end portion of the deck assembly.
12. The treadmill of claim 9 , further comprising a cable that operatively connects the handle to the pin.
13. The treadmill of claim 9 , further comprising a spring operatively connected to the handle to bias the pin towards an engaged position.
14. The treadmill of claim 1 , further comprising a lift assistance mechanism operatively connected to the frame and the deck assembly.
15. The treadmill of claim 14 , wherein the lift assistance mechanism is at least partially received inside the first tube and the second tube.
16. The treadmill of claim 1 , wherein the first tube is telescopically received in the second tube.
17. The treadmill of claim 1 , further comprising an actuator operatively coupled to the pin to disengage the pin from the slot, wherein the actuator is positioned on the treadmill such that the actuator is accessible to a user when the deck assembly is in the operating position.
