Abstract

A drain snake may include a hollow body having a rearward end and a forward end, and a longitudinal axis extending between the rearward and forward ends. The forward end has a cable feed passage. The drain snake may further include a cable having a first portion coiled in the body around the axis in a location between the rearward and forward ends. The cable has a second portion extending out of the feed passage of the forward end of the hollow body. The drain snake also include a fastener extending through the body at the forward end and into the feed passage to secure and release the cable.

Claims (47)

1. A drain snake, comprising:

a hollow body including:

a rearward end,

a forward end having a cable feed passage, and

a longitudinal axis extending between the rearward and forward ends;

a cable including:

a first portion coiled in the body around the axis in a location between the rearward and forward ends, and

a second portion extending out of the feed passage of the forward end of the hollow body; and

a fastener extending through the body at the forward end and into the feed passage to secure and release the cable,

wherein the rearward end of the hollow body includes no handle protruding away therefrom, has finger recesses to establish a finger grip, and is flat to facilitate resting of the drain snake thereon.

2. The drain snake of claim 1 , wherein the drain snake is crankless, such that the drain snake has no crank rotatable relative to another portion of the body and no handle rotatable relative to another portion of body.

3. The drain snake of claim 1 , wherein the finger recesses include apertures.

4. The drain snake of claim 1 , wherein the finger grip is wave-shaped.

5. The drain snake of claim 1 , wherein the hollow body includes:

a cylindrical portion adjacent the rearward end,

an incurvate portion extending away from the cylindrical portion and decreasing in diameter, and

an excurvate portion extending away from the excurvate portion and continuing to decrease in diameter and then increasing in diameter to flare outwardly at the forward end.

6. The drain snake of claim 5 , wherein the forward end includes a neck extending about the cable feed passage, the neck defining an outwardly facing concave surface.

7. The drain snake of claim 6 , wherein the outwardly facing concave surface is configured to guide a force applied radially inwardly upon the neck to a fixed axial position with respect to the rearward end of the hollow body.

8. The drain snake of claim 6 , wherein the outwardly facing concave surface includes forward and rearward portions and a midpoint disposed therebetween;

wherein the forward portion increases in outer diameter from the midpoint in a forward direction, and the rearward portion increases in outer diameter from the midpoint in a rearward direction.

9. The drain snake of claim 8 , wherein the outwardly facing concave surface is configured to guide a force applied radially inwardly upon the neck to a fixed axial position with respect to the rearward end of the hollow body, the fixed axial position corresponding to the midpoint of the outwardly facing concave surface.

10. The drain snake of claim 1 , wherein the fastener includes a screw collar and a screw extending through the screw collar transversely into the feed passage.

11. The drain snake of claim 1 , consisting essentially of the hollow body, the cable, and the fastener.

12. The drain snake of claim 1 , wherein the drain snake has no handle rotatable relative to another portion of the body.

13. The drain snake of claim 1 , wherein the rearward end of the hollow body defines a plurality of apertures configured to facilitate gripping the rearward end and drainage of the hollow body.

14. A drain snake, comprising:

a hollow body including:

a rearward end,

a forward end having a cable feed passage, and

a longitudinal axis extending between the rearward and forward ends;

a cable including:

a first portion coiled in the body around the axis in a location between the rearward and forward ends, and

a second portion extending out of the feed passage of the forward end of the hollow body, and

wherein the hollow body includes:

a rear wall at the rearward end extending transversely with respect to the axis,

a front wall at the forward end including a portion extending transversely with respect to the axis and another portion extending parallel to the axis and having the feed passage with the second portion of the cable extending therethrough, and

a sidewall extending between the rear and front walls and extending beyond the front wall to establish a skirt that at least partially defines an open reservoir at the forward end.

15. The drain snake of claim 14 , wherein the rear wall establishes a rearmost surface and includes no handle protruding away therefrom.

16. A drain snake, comprising:

a hollow body including:

a rearward end includes no handle protruding away therefrom, has finger recesses to establish a finger grip, and is flat thereby facilitating resting the drain snake thereon,

a forward end having a cable feed passage and an open reservoir, and

a longitudinal axis extending between the rearward and forward ends; and

a cable including:

a first portion coiled in the body around the axis in a location between the rearward and forward ends, and

a second portion extending out of the feed passage of the forward end of the hollow body.
