Abstract

A drain cleaner includes a drum assembly configured to store a cable and an actuator assembly movable relative to the drum assembly between a neutral position, where the cable is free to spin and translate out of the drum assembly, an autofeed position, where the cable is allowed to spin and is automatically driven out of the drum assembly, and an autofeed locked on position, where the actuator assembly is maintained in the autofeed position without continuous input from a user. The actuator assembly includes a handle supported by the drum assembly and an autofeed locking mechanism. The autofeed locking mechanism includes a drive lock and a lock release. The drive lock engages the handle to maintain the actuator assembly in the autofeed locked on position.

First claim

What is claimed is:

1. A drain cleaner comprising:
a drum assembly configured to store a cable; and
an actuator assembly movable relative to the drum assembly between a neutral position, where the cable is free to spin and translate out of the drum assembly, an autofeed position, where the cable is allowed to spin and is automatically driven out of the drum assembly, and an autofeed locked on position, where the actuator assembly is maintained in the autofeed position without continuous input from a user, the actuator assembly including a handle supported by the drum assembly and an autofeed locking mechanism, the autofeed locking mechanism includes a drive lock and a lock release, the drive lock engages the handle to maintain the actuator assembly in the autofeed locked on position;
wherein the handle includes an abutment on an interior surface, and wherein the drive lock includes a wing that engages the abutment to maintain the actuator assembly in the autofeed locked on position; and
wherein the wing is biased radially outward to engage the abutment.

2. The drain cleaner of claim 1 , wherein the actuator assembly is biased to the neutral position.

3. The drain cleaner of claim 1 , wherein the drive lock is moveable relative to the drum assembly, and wherein the lock release is stationary relative to the drum assembly.

4. The drain cleaner of claim 1 , wherein the actuator assembly moves linearly between the neutral position, the autofeed position, and the autofeed locked on position.

5. The drain cleaner of claim 1 , wherein the actuator assembly is movable between the neutral position and the autofeed position in a direction towards the drum assembly.

6. The drain cleaner of claim 5 , wherein the actuator assembly is moveable between the autofeed position and the autofeed locked on position in the direction towards the drum assembly.

7. The drain cleaner of claim 1 , wherein the actuator assembly is movable between the autofeed locked on position and the autofeed position in a direction away from the drum assembly.

8. The drain cleaner of claim 1 , wherein the actuator assembly is further movable to a locked position, where the cable is allowed to spin, but cannot move relative to the drum assembly.

9. The drain cleaner of claim 1 , wherein the actuator assembly further includes a collet that engages the cable in the autofeed position to automatically drive the cable out of the drum assembly.

10. A drain cleaner comprising:
a drum assembly configured to store a cable, the drum assembly including a nose with a first portion and a second portion; and
an actuator assembly movable relative to the drum, the actuator assembly including,
a handle supported by the nose of the drum assembly, the handle including an inlet, an outlet opposite the inlet, a passage extending between the inlet and the outlet, and an abutment on an inside surface of the passage,
a cable locking mechanism positioned within the handle, and
an autofeed locking mechanism positioned within the handle, the autofeed locking mechanism including a drive lock positioned on the second portion of the nose and a lock release positioned on the second portion of the nose;

wherein the actuator assembly is moveable between a neutral position, where the cable is free to spin and translate out of the drum assembly, an autofeed position, where the cable is allowed to spin and is automatically driven out of or into the drum assembly, and a locked position, where the cable is able to spin, but not allowed to travel out of or into the drain cleaner; and
wherein the drive lock engages the abutment of the handle to maintain the actuator assembly in the autofeed position;
wherein the drive lock is movable relative to the drum assembly, and wherein the lock release is stationary relative to the drum assembly; and
wherein the drive lock includes a wing that is biased radially outwards to engage the abutment of the handle to maintain the actuator assembly in the autofeed position, and wherein the lock release includes a disengagement tab.

11. The drain cleaner of claim 10 , wherein, when the actuator assembly is in the autofeed position, moving the actuator assembly away from the drum assembly slides the wing of the drive lock into engagement with the disengagement tab to disengage the wing from the abutment of the handle to release the actuator assembly from the autofeed position.

12. A drain cleaner comprising:
a drum assembly configured to store a cable; and
an actuator assembly movable relative to the drum assembly between a neutral position, where the cable is free to spin and translate out of the drum assembly, an autofeed position, where the cable is allowed to spin and is automatically driven out of the drum assembly, and an autofeed locked on position, where the actuator assembly is maintained in the autofeed position without continuous input from a user, the actuator assembly including a handle supported by the drum assembly and an autofeed locking mechanism, the autofeed locking mechanism includes a drive lock and a lock release, the drive lock engages the handle to maintain the actuator assembly in the autofeed locked on position;
wherein the actuator assembly further includes a collet that engages the cable in the autofeed position to automatically drive the cable out of the drum assembly.
