Abstract
A drain cleaning system is described that includes a drain cleaning device with a flexible drain cleaning cable, and two or more sections of guide hoses that can be attached to one another and/or to the device. Also described are systems that include provisions for advancing or retracting the drain cleaning cable and which can also be coupled to one or more of the guide hoses.
Claims8
In a drain cleaning system comprising:
- a drain cleaning device (10) including a rotatable drum (40) and a flexible drain cleaning cable (14) advanceable from the drum (40);
- wherein the improvement comprises:
- a first bi-ended flexible guide hose (110a), one of the ends (112a) of the first flexible guide hose (110a) being coupled to the drain cleaning device (10), the first flexible guide hose (110a) being positioned for housing the drain cleaning cable (14) being advanced from the drum (40);
- a second bi-ended flexible guide hose (110b), one of the ends (112b) of the second flexible guide hose (110b) being selectively and releasably coupled to the other end (114a) of the first flexible guide hose (110a) through frictional engagement of contacting surface portions therebetween;
- wherein the frictional engagement of the contacting surface portions is provided by a male coupling member (112b) on one of the first and second guide hoses (110a, 110b) and an associated female coupling member (114a) on the other of the first and second guide hoses (110a, 110b);
- wherein the male coupling member (112b) includes a coupling portion defining an axial projection (116) of predetermined length, the axial projection (116) having a substantially uniform diameter and a substantially uniformly-smooth exterior surface substantially along its length;
- and
- wherein the female coupling member (114a) includes a coupling portion defining a hollow region configured to receive the axial projection (116) of the male coupling member (112b).

In a drain cleaning system comprising:
- a drain cleaning device (10) including a rotatable drum (40) and a flexible drain cleaning cable (14) advanceable from the drum (40);
- wherein the improvement comprises:
- a modular guide hose system (100) comprising a plurality of flexible bi-ended guide hose sections, wherein one of the ends (112a) of a first one (110a) of the plurality of flexible bi-ended guide hose sections is coupled to the drain cleaning device (10), the first one (110a) of the plurality of flexible guide hose sections being positioned for housing the drain cleaning cable (14) being advanced from the drum (40);
- wherein one of the ends (112b) of a second one (110b) of the plurality of bi-ended flexible guide hose sections is selectively and releasably coupled to the other end (114a) of the first one (110a) of the flexible bi-ended guide hose sections through frictional engagement of contacting surface portions therebetween;
- wherein the frictional engagement of the contacting surface portions is provided by a male coupling member (112b) on one of the first and second guide hose sections (110b) of the plurality of bi-ended flexible guide hose sections and an associated female coupling member (114a) on the other of the first and second guide hose sections (110a) of the plurality of flexible bi-ended guide hose sections
- wherein the male coupling member (112b) includes a coupling portion defining an axial projection (116) of predetermined length, the axial projection (116) having a substantially uniform diameter and a substantially uniformly-smooth exterior surface substantially along its length;
- and
- wherein the female coupling member (114a) includes a coupling portion defining a hollow region configured to receive the axial projection (116) of the male coupling member (112b).
