Abstract

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame, a leg unit, and a leg lock assembly. The leg unit is movably coupled to the frame. The leg unit includes a first leg and a second leg spaced apart from the first leg. The leg lock assembly is operatively coupled to the leg unit and located partially within the frame. The leg lock assembly is configured to lock the leg unit in a first position relative to the frame when the portable grill is in the erected configuration, and to unlock the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration.

First claim

What is claimed is:

1. A portable grill movable between an erected configuration and a collapsed configuration, the portable grill comprising:
a frame;
a support member rigidly coupled to the frame;
a leg unit movably coupled to the frame, the leg unit including a first leg and a second leg spaced apart from the first leg; and
a leg lock assembly operatively coupled to the leg unit and located partially within the frame, the leg lock assembly including:
a lever pivotally coupled to the support member, the lever rotatable relative to the support member between a lowered position and a raised position; and
a handle slidably coupled to the lever, the handle slidable relative to the lever between a retracted position and an extended position, the handle biased into the retracted position, the handle actuatable to rotate the lever between the lowered position and the raised position;

wherein the leg lock assembly is configured to:
lock the leg unit in a first position relative to the frame when the portable grill is in the erected configuration; and
unlock the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration, the unlocking to occur in response to (1) actuation of the handle from the retracted position into the extended position, followed by (2) actuation of the lever, via the handle, from the lowered position into the raised position.

2. The portable grill of claim 1 wherein the leg lock assembly further includes a tension spring configured to bias the handle into the retracted position.

3. The portable grill of claim 1 wherein the leg lock assembly further includes a handle lift blocker configured to selectively engage a handle lift stop coupled to the support member, the handle lift stop configured to:
prevent movement of the lever from the lowered position into the raised position when the handle is in the retracted position; and
enable movement of the lever from the lowered position into the raised position when the handle is in the extended position.

4. The portable grill of claim 1 wherein the leg lock assembly further includes a lockbar and a link, the lockbar located within the frame, the link extending between the lever and the lockbar, the link configured to transfer movement of the lever to the lockbar.

5. The portable grill of claim 4 , wherein the lockbar pivots within the frame in response to movement of the lever from the lowered position into the raised position, wherein the pivoting of the lockbar within the frame unlocks the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration.

6. The portable grill of claim 5 , wherein the lockbar is pivotally coupled to a spring carrier located at least partially within the frame, the spring carrier carrying a torsion spring, the torsion spring biasing the lockbar into an orientation that maintains the leg unit in the first position when the portable grill is in the erected configuration and the lever is in the lowered position.

7. The portable grill of claim 6 , wherein the lockbar includes a slot configured to receive a locking pin, the locking pin operatively coupled to the first leg or the second leg of the leg unit, the slot including a linear portion and a notch extending at an angle away from the linear portion, the locking pin movable within the slot from the notch into the linear portion in response to the lockbar being pivoted against the biasing of the torsion spring to alter the orientation of the lockbar, wherein the leg lock assembly is configured to:
lock the leg unit in the first position when the locking pin is located in the notch of the slot; and
unlock the leg unit from the first position when the locking pin is located in the linear portion of the slot.

8. The portable grill of claim 7 , wherein the locking pin is coupled to a locking pin carrier located within the frame, the locking pin carrier is coupled to a slider located within and slidable relative to the frame, the slider is coupled to a flange of the leg unit, and the first leg or the second leg of the leg unit is pivotally coupled to the flange.

9. A portable grill movable between an erected configuration and a collapsed configuration, the portable grill comprising:
a frame including a front rail and a rear rail spaced apart from the front rail;
a support plate rigidly coupled to the frame, the support plate extending between the front and rear rails;
a cookbox coupled to and supported by the frame, the cookbox located between the front and rear rails;
a leg unit movably coupled to the frame, the leg unit including a front leg and a rear leg spaced apart from the front leg; and
a leg lock assembly operatively coupled to the leg unit and located partially within the rear rail, the leg lock assembly including:
a lever located below and pivotally coupled to the support plate, the lever rotatable relative to the support plate between a lowered position and a raised position; and
a handle located below the support plate and slidably coupled to the lever, the handle slidable relative to the lever between a retracted position and an extended position, the handle biased into the retracted position, the handle actuatable to rotate the lever between the lowered position and the raised position;

wherein the leg lock assembly is configured to:
lock the leg unit in a first position relative to the frame when the portable grill is in the erected configuration; and
unlock the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration, the unlocking to occur in response to (1) actuation of the handle from the retracted position into the extended position, followed by (2) actuation of the lever, via the handle, from the lowered position into the raised position.

10. The portable grill of claim 9 , wherein the leg lock assembly further includes a handle lift blocker configured to selectively engage a handle lift stop coupled to the support plate, the handle lift stop configured to:
prevent movement of the lever from the lowered position into the raised position when the handle is in the retracted position; and
enable movement of the lever from the lowered position into the raised position when the handle is in the extended position.

11. The portable grill of claim 9 , wherein the leg lock assembly further includes a lockbar and a link, the lockbar located within the rear rail, the link extending between the lever and the lockbar, the link configured to transfer movement of the lever to the lockbar.

12. The portable grill of claim 11 , wherein the lockbar pivots within the rear rail in response to movement of the lever from the lowered position into the raised position, wherein the pivoting of the lockbar within the rear rail unlocks the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration.

13. The portable grill of claim 12 , wherein the lockbar is pivotally coupled to a spring carrier located at least partially within the rear rail, the spring carrier carrying a torsion spring, the torsion spring biasing the lockbar into an orientation that maintains the leg unit in the first position when the portable grill is in the erected configuration and the lever is in the lowered position.

14. The portable grill of claim 13 , wherein the lockbar includes a slot configured to receive a locking pin, the locking pin operatively coupled to the rear leg of the leg unit, the slot
