Abstract

A closet auger includes an elongated casing member extending along an axis, and an elongated drive member telescopically received in the casing member and movable between an extended position and a retracted position relative to the casing member along the axis. The drive member is rotatable relative to the casing member about the axis. The closet auger further includes a flexible cable having an end removably connectable to the drive member in first and second configurations, where a length of the flexible cable is retracted within or extended from the drive member, respectively. A cable retention assembly is supported by the casing member and selectively engageable with the flexible cable to inhibit movement of the flexible cable relative to the casing member. The drive member is movable relative to the flexible cable when the cable retention assembly engages the flexible cable to change between the first and second configurations.

First claim

What is claimed is:

1. A closet auger comprising:
an elongated casing member extending along an axis;
an elongated drive member telescopically received in the casing member and movable between an extended position and a retracted position relative to the casing member along the axis, the drive member being rotatable relative to the casing member about the axis;
a flexible cable having an end removably connectable to the drive member in a first configuration, where a length of the flexible cable is retracted within the drive member, and a second configuration, where the length of the flexible cable extends from the drive member; and
a cable retention assembly supported by the casing member, the cable retention assembly configured to selectively engage the flexible cable to inhibit movement of the flexible cable relative to the casing member, the drive member being movable relative to the flexible cable when the cable retention assembly engages the flexible cable to change between the first configuration and the second configuration.

2. The closet auger of claim 1 , wherein the cable retention assembly includes a cable retention member movable radially inward relative to the casing member to engage the flexible cable.

3. The closet of auger of claim 2 , wherein the cable retention member is a flexible spring member having a first end and a second end, and wherein the first end is fixed to the casing member and the second end is biased radially outward from the casing member and movable radially inward relative to the casing member to engage the flexible cable.

4. The closet auger of claim 2 , wherein the cable retention assembly includes a cam member selectively movable along the axis relative to the casing member to move the cable retention member radially inward to engage the flexible cable.

5. The closet auger of claim 4 , wherein the cable retention assembly includes a movable handle to which the cam member is coupled for movement therewith.

6. The closet auger of claim 1 , wherein the end of the flexible cable is connected adjacent to a first end of the drive member when in the first configuration, and is connected adjacent to a second end of the drive member when in the second configuration.

7. The closet auger of claim 6 , wherein the drive member includes a first aperture adjacent the first end and a second aperture adjacent the second end, and wherein the end of the flexible cable includes a spring biased detent that engages the first aperture when in the first configuration and engages the second aperture when in the second configuration.

8. The closet auger of claim 7 , further comprising:
a handle movable relative to the casing member; and
a detent release mechanism coupled to the handle for movement with the handle, the detent release mechanism selectively engageable with the spring biased detent as the handle moves to disengage the spring biased detent from the first aperture and the second aperture.

9. The closet auger of claim 8 , wherein the cable retention assembly is also coupled to the handle for movement with the handle, and wherein the cable retention assembly engages the flexible cable in response to movement of the handle simultaneously with movement of the detent release mechanism.

10. The closet auger of claim 1 , further comprising a manual crank handle or a motorized drive unit connected to an end of the drive member to rotatably drive the drive member about the axis relative to the casing member.

11. A method of using a closet auger, the closet auger including an elongated casing member extending along an axis, an elongated drive member telescopically received in the casing member and being rotatable relative to the casing member about the axis, a flexible cable having an end, and a cable retention assembly supported by the casing member, the method comprising:
connecting the end of the flexible cable to the drive member in a first configuration, where a length of the flexible cable is retracted within the drive member;
gripping the flexible cable with the cable retention assembly to inhibit movement of the flexible cable relative to the casing member;
disconnecting the end of the flexible cable from the drive member;
sliding the drive member relative to the casing member and the flexible cable from a retracted position to an extended position; and
connecting the end of the flexible cable to the drive member in a second configuration, where the length of the flexible cable extends from the drive member.

12. The method of claim 11 , wherein the cable retention assembly includes a cable retention member, and further comprising moving the cable retention member radially inward toward the axis to engage the flexible cable.

13. The method of claim 12 , wherein the cable retention assembly also includes a cam member, and further comprising moving the cam member along the casing member to move the cable retention member radially inward toward the axis.

14. The method of claim 13 , wherein the cable retention member is a flexible spring member having a first end fixed to the casing member and a second end biased radially outward away from the axis.
