Abstract

Wheeled transport carts are described which are configured for transporting drain cleaning equipment such as drain cleaning machines and drain cleaning cable. The carts include engagement provisions that enable a drain cleaning machine to be affixed to the cart and preclude unintended separation from the cart during use or transport. The engagement provisions also enable the drain cleaning machine to be quickly and easily separated from the cart. Also described are methods of transporting such equipment using the carts. In addition, systems of the cart(s) with various equipment are described.

First claim

What is claimed is:

1. A transport cart comprising:
a frame defining a proximal end and an opposite distal end, the frame defining a frame longitudinal axis extending between the proximal end and the distal end, the frame including at least one wheel rotatably secured to the frame adjacent the distal end;
engagement provisions secured to the frame, the engagement provisions including (i) a first member adjacent the distal end of the frame, the first member including a first receiving slot defining a first longitudinal axis, and (ii) a second member between the proximal end of the frame and the first member, the second member including a second receiving slot defining a second longitudinal axis, wherein both the first receiving slot and the second receiving slot are accessible from the proximal end of the frame;
a stairs support bracket secured to the frame and positioned such that the bracket extends tangential or nearly tangential to the at least one wheel.

2. The transport cart of claim 1 wherein the axis of the first receiving slot is nonparallel with the axis of the second receiving slot.

3. The transport cart of claim 1 wherein the axis of the first receiving slot is oriented parallel with the longitudinal axis of the cart.

4. The transport cart of claim 1 wherein the axis of the second receiving slot is oriented at an acute angle to the longitudinal axis of the cart.

5. The transport cart of claim 1 further comprising:
a kickstand assembly secured to the frame, the kickstand assembly including a kickstand positionable between a storage position and a use position, wherein upon orienting the frame to rest upon an underlying surface, and positioning the kickstand to the use position, the at least one wheel is free from contact with the underlying surface.

6. The transport cart of claim 1 further comprising:
at least one handle secured to the frame adjacent the proximal end of the frame.

7. The transport cart of claim 1 further comprising:
at least one leg extending from the frame.

8. The transport cart of claim 1 further comprising:
at least one mounting arm extending from the frame.

9. The transport cart of claim 1 further comprising:
at least one floor support extending rearwardly from the frame such that upon resting the cart on a floor surface, the frame extends along a longitudinal axis that is nonparallel to the floor surface.

10. The transport cart of claim 6 wherein the longitudinal axis of the frame extends at an angle to the floor surface within a range of from 1° to 10°.

11. The transport cart of claim 1 wherein the engagement provisions are latch-free.

12. The transport cart of claim 10 wherein the engagement provisions are latch-free.

13. A method of transporting a drain cleaning machine, the method comprising:
providing a transport cart including (a) a frame defining a proximal end and an opposite distal end, the frame defining a longitudinal axis extending between the proximal end and the distal end, the frame including at least one wheel rotatably secured to the frame adjacent the distal end, and (b) engagement provisions secured to the frame, the engagement provisions including (i) a first member adjacent the distal end of the frame defining a first receiving slot having a longitudinal axis, and (ii) a second member between the proximal end of the frame and the first member, the second member defining a second receiving slot having a longitudinal axis, wherein both of the first receiving slot and the second receiving slot are accessible from the proximal end of the frame;
aligning a first portion of a frame of the drain cleaning machine with the first receiving slot;
aligning a second portion of the frame of the drain cleaning machine with the second receiving slot;
moving the drain cleaning machine relative to the cart such that the frame of the drain cleaning machine is positioned in both of the first receiving slot and the second receiving slot.

14. The method of claim 13 wherein the moving operation simultaneously positions the frame of the drain cleaning machine into both of the first receiving slot and the second receiving slot.

15. A system comprising:
a drain cleaning machine; and
a transport cart including a frame defining a proximal end and an opposite distal end, the frame defining a longitudinal axis extending between the proximal end and the distal end, the frame including at least one wheel rotatably secured to the frame adjacent the distal end, and engagement provisions secured to the frame, the engagement provisions including (i) a first member adjacent the distal end of the frame defining a first receiving slot having a longitudinal axis, and (ii) a second member between the proximal end of the frame and the first member, the second member defining a second receiving slot having a longitudinal axis, wherein both of the first receiving slot and the second receiving slot are accessible from the proximal end of the frame.

16. The system of claim 15 wherein the axis of the first receiving slot is nonparallel with the axis of the second receiving slot.

17. The system of claim 15 wherein the axis of the first receiving slot is oriented parallel with the longitudinal axis of the cart.

18. The system of claim 15 wherein the axis of the second receiving slot is oriented at an acute angle to the longitudinal axis of the cart.

19. The system of claim 15 wherein the drain cleaning machine includes a first retention component and a second retention component, the drain cleaning machine being engageable to the transport cart by positioning the first retention component in the first receiving slot and positioning the second retention component in the second receiving slot.
