Abstract

Described is a drain cleaner assembly, including: a clamp knob having a central cavity therein for accommodating a drain snake; a spout having a central cavity therein for accommodating the drain snake; the spout having at least one gripper cavity therein; at least one gripper disposed in the at least one gripper cavity; the clamp knob and the spout being attached to one another and also being displaceable with respect to one another to achieve at least two orientations, the at least two orientations comprising: a first orientation wherein the clamp knob contacts the at least one gripper and forces the at least one gripper into securing contact with the drain snake; and a second orientation wherein the clamp knob permits the at least one gripper to transition within the at least one gripper cavity to be out of securing contact with the drain snake. Other aspects are described and claimed.

Claims (39)

1. A drain cleaner assembly, comprising:

a drain snake;

a clamp knob having a central cavity therein for accommodating the drain snake;

a spout having a central cavity therein for accommodating the drain snake;

the spout having at least one gripper cavity therein;

at least one gripper disposed in the at least one gripper cavity, wherein the gripper is able to move freely within the at least one gripper cavity;

the at least one gripper comprising substantially straight sides and further comprising end portions comprising a substantially flat portion positioned between angular portions, wherein the angular portions are angled with respect to: the substantially straight sides of the at least one gripper and the substantially flat portion;

the clamp knob and the spout being attached to one another and also being displaceable with respect to one another to achieve at least two orientations, the at least two orientations comprising:

a first orientation wherein the clamp knob contacts the at least one gripper and forces the at least one gripper into securing contact with the drain snake; and

a second orientation wherein the clamp knob permits the at least one gripper to transition within the at least one gripper cavity to be out of securing contact with the drain snake.

2. The drain cleaner assembly of claim 1 , wherein the clamp knob and the spout comprise complementary threading.

3. The drain cleaner assembly of claim 2 , wherein the clamp knob and the spout displace with respect to one another to achieve the at least two orientations via rotating about the complementary threading.

4. The drain cleaner assembly of claim 1 , wherein the substantially straight sides of the at least one gripper correspond to substantially straight sides of the at least one gripper cavity.

5. The drain cleaner assembly of claim 1 , wherein the at least one gripper is substantially symmetric about a central axis.

6. The drain cleaner assembly of claim 1 , further comprising a retaining ring disposed on the spout;

wherein the retaining ring is positioned on the spout to inhibit removal of the clamp knob from the spout.

7. The drain cleaner assembly of claim 1 , wherein:

the at least one gripper comprises three grippers; and

the at least one gripper cavity comprises three gripper cavities.

8. The drain cleaner assembly of claim 1 , further comprising:

a drum assembly configured to house the drain snake; and

a shaft element configured to accommodate one or more of a hand crank and a motorized drill.

9. The drain cleaner assembly of claim 1 , further comprising a drum assembly configured to house the drain snake; and

a grip sleeve disposed on the spout, wherein the grip sleeve is located between the clamp knob and drum assembly.

10. A ball typo clamp assembly, comprising:

a clamp knob having a central cavity therein for accommodating a rotatable element;

a spout having a central cavity therein for accommodating the rotatable element;

the spout having at least one gripper cavity therein;

at least one gripper disposed in the at least one gripper cavity, wherein the at least one gripper is able to move freely within the at least one gripper cavity;

the at least one gripper comprising substantially straight sides and further comprising end portions comprising a substantially flat portion positioned between angular portions, wherein the angular portions are angled with respect to: the substantially straight sides of the at least one gripper and the substantially flat portion;

the clamp knob and the spout being attached to one another and also being displaceable with respect to one another to achieve at least two orientations, the at least two orientations comprising:

a first orientation wherein the clamp knob contacts the at least one gripper and forces the at least one gripper into securing contact with the rotatable element; and

a second orientation wherein the clamp knob permits the at least one gripper to transition within the at least one gripper cavity to be out of securing contact with the rotatable element.

11. The clamp assembly of claim 10 , wherein the clamp knob and the spout comprise complementary threading.

12. The clamp assembly of claim 11 , wherein the clamp knob and the spout displace with respect to one another to achieve the at least two orientations via rotating about the complementary threading.

13. The clamp assembly of claim 10 , wherein the substantially straight sides of the at least one gripper correspond to substantially straight sides of the at least one gripper cavity.

14. The clamp assembly of claim 10 , further comprising a retaining ring disposed on the spout;

wherein the retaining ring is positioned on the spout to inhibit removal of the clamp knob from the spout.

15. The clamp assembly of claim 10 , further comprising a grip sleeve disposed on the spout.
