ABSTRACT:
TECHNICAL FIELD
This invention relates to apparatus for supporting a conduit for transporting fluent material above the surface. The invention has particular application to waste discharge conduits such as those employed in association with recreational vehicles, campers and trailer homes.
BACKGROUND OF THE INVENTION
It is common practice to discharge waste from recreational vehicles, trailer homes, campers and the like through conduits which receive effluent from a discharge outlet and convey the material to a holding tank, treatment facility or other location.
Typically, waste discharge conduits are maintained in a non-level condition to allow discharge under the influence of gravity, the conduits being positioned at the desired altitude and orientation by supports in the form of stacks of bricks, boards or other objects which are at hand. Not only does this present an unsightly appearance, the person carrying out the discharge operation may have difficulty providing proper stability and placement of the conduit. Furthermore, such objects are not always readily available at the discharge site, the alternative being to carry such objects around in the vehicle. This uses up valuable space and can be highly inconvenient, particularly when the support objects are bulky and heavy, an example being bricks or cement blocks.
DISCLOSURE OF INVENTION
The present invention relates to apparatus which quickly and reliably can be used to support a conduit for transporting fluent material above a surface in a highly stable manner. Furthermore, the apparatus may be quickly installed in place. During use the apparatus presents a pleasing appearance as compared to typical supports currently employed. Furthermore, the apparatus assumes a very compact configuration when not in use so that it can be readily transported and stowed away in a vehicle.
The apparatus includes a first support member having an upper end and a lower end, the upper end of the first support member being positionable adjacent to and under a conduit and the lower end of the first support member being positionable at a surface.
The apparatus also includes a second support member having an upper end and a lower end, the upper end of the second support member being positionable adjacent to and under the conduit next to the upper end of the first support member and the lower end of the second support member being positionable at a surface.
Hinge means hingedly connects the first and second support members at the lower ends thereof whereby the upper ends of the first and second support members can be moved toward or away from one another upon relative pivotal movement of the first and second support members at the hinge means.
A Lock means is cooperable with the first and second support members for selectively locking the first and second support members against relative movement to retain the upper ends of the first and second support members a desired distance from one another. The disclosed apparatus includes a plurality of support units to be spaced from one another along a length of the conduit being supported, the support units being of different sizes.
Other features, advantages, and objects of the present invention will become apparent with reference to the following description and accompanying drawings.
