Locking device to lock a collapsible treadmill deck in a folded position
First Claim
1. A locking device for a treadmill having a collapsible treadmill deck and a base assembly to lock the collapsible treadmill deck in a folded position relative to the base assembly, and the locking device comprising:
- a telescopic tube comprisingan outside tube having an exterior periphery, a bottom end pivotally connected to the base assembly and a through hole defined through the exterior periphery; and
an inside tube telescopically mounted in the outside tube and having an exterior periphery, a top end pivotally connected to the collapsible treadmill deck and at least one positioning hole defined through the exterior periphery of the inside tube, and each of the at least one positioning holes corresponding to the through hole, wherein each of the at least one positioning hole has an annular edge, an inclined surface defined along the annular edge and at least one slot defined at the annular edge to allow the locking pin to selectively extend into one of the at least one positioning hole; and
a lock attached to the exterior periphery of the outside tube, aligned with the through hole and comprisinga mounting bracket fastened on the exterior periphery of the outside tube and having a stationary end, a free end and a passage defined through the free end to the stationary end, aligned with the through hole and having an interior periphery;
an adjusting knob rotatably and retractably mounted at the free end of the mounting bracket; and
a detent assembly movably mounted in the passage and comprising a rotating shaft and a locking pin, the rotating shaft having an exterior surface, an inside end and an outside end, and the locking pin attached to the exterior surface of the rotating shaft at the inside end;
wherein the locking pin is selectively extendable into one of the at least one positioning hole to engage the inside tube as the adjusting knob is pushed and rotated.

Abstract
A locking device to lock a collapsible treadmill deck in a folded position includes a telescopic tube and a lock. The telescopic tube includes an outside tube and an inside tube. The outside tube has a though hole. The inside tube is telescopically mounted in the outside tube and has multiple positioning holes corresponding to the through hole. The lock is attached to the outside tube, aligned with the through hole and includes a mounting bracket, an adjusting knob and a detent assembly. The adjusting knob is rotatably and retractably mounted on the mounting bracket. The detent assembly includes a rotating shaft with a locking pin movably mounted in the mounting bracket and connected to the adjusting knob. Therefore, the locking pin will be pulled into one of the positioning holes to engage the inside tube by pushing the adjusting knob toward the mounting bracket.
