The present invention relates, in general, to tools and, more particularly, this invention relates to tools to aid in lifting toilets.
Prior to the conception and development of the present invention, tools as are generally well known in the prior art, have been used to attempt to make moving toilets easier. Specifically of interest to the present invention are the following: Merrill, U.S. Pat. No. 6,886,192 discloses a toilet lifting and transport device. The device has forward legs and rear legs, with the forward legs being deployable in an open configuration for lifting and transporting use, and a closed configuration for storage. A screw lift is positioned on at least one horizontal support that is positioned between the rear legs. The lifting device is coupled to a toilet fixture via a tank strap and bridge straps. Lifting of the toilet fixture is then accomplished utilizing the screw lift. Transport of the lifting device with the toilet fixture thereon is accomplished by rolling the lifting device on wheels located on the bottoms of the rear and forward legs.
Gwynn, U.S. Pat. No. 6,685,170 discloses a collapsible apparatus for lifting and transporting objects, such as toilets and similar plumbing fixtures. The toilet lifter has a support structure and a strap system attached thereto. The support structure has three vertical legs with wheels on the bottoms and horizontal support structures connecting the legs at the tops. The strap system is supported by the support structure above the toilet in use and passes across a pivot point on the support structure to raise and lower the toilet.
Decky, et al, U.S. Pat. No. 5,373,593 discloses a hand cart for lifting, transporting and installing toilets, including a wheeled base and frame designed to straddle a toilet. The lifting member includes a hand operated screw jack and ball engaging grapples and a rim clamp to securely hold the toilet on the cart during the lifting and transporting process.
Chitwood, U.S. Pat. No. 4,722,511 discloses a lifting and transporting device for toilets including a wheeled frame to which a pair of moveable lifting bars are attached. Moveable support collars and adjustable lifting rods are attached to the lifting bars, and the collars and rods are selectively positionable about a toilet to perform a holding and supporting function. The lifting bars are selectively vertically moveable by a hand actuated threaded rod. After a toilet has been lifted from the floor, it can be transported by the invention to a desired location and then lowered into position by a reverse operation of the threaded lifter.
Wall, U.S. Pat. No. 6,752,379 discloses a toilet dolly. A “U”-shaped frame slides around either side of the toilet bowl. The frame comprises two arms that are adjustable to fit any size bowl or any difficult installation and are connected to a cross-arm. Padded lifting arms are provided to lock in place around the bowl. The two toilet mounting nuts are removed and a series of three jack screws are raised in an alternating fashion to allow the bowl assembly to clear the floor-mounted fastening bolts. Once clear, the bowl can be rolled out of the bathroom. The bowl can be reinstalled by a similar but reverse process. The actually raising of the jack screw can be accomplished with an electrical drill, including cordless drills, and/or a ratchet.
Irwin, U.S. Pat. No. 6,135,466 discloses an article transport cart which is specially designed for lifting and transporting both toilets and urinals. The transport cart includes strategically located, adjustable lifting arms which can be used to engage and conveniently lift either a toilet or a urinal. The lifting arms and a tow plate can be adjusted relative to the cart frame so that they can be conveniently moved from an outwardly extending, operating configuration into a stowed position to enable the cart to be conveniently stored and transported. A locking mechanism is provided for locking the foldable toe plate in an operating position to stabilize the device when it is used to lift and transport wall-mounted urinals. The cart also includes a foldable toilet stabilizing means for restrainably engaging and stabilizing the toilet during lifting and transport.
The present invention provides an apparatus for lifting, supporting, and transporting a toilet. A frame member includes a pair of side members, each of such pair of side members having a generally horizontally disposed portion and a generally vertically disposed portion. Such frame member further includes a bracing means engageable with each of such side members for maintaining a predetermined distance between inner surfaces thereof. Wheel members are disposed on a bottom surface of such pair of side members closely adjacent each end thereof. A supporting mechanism is disposed within such horizontally disposed portion of such side members for at least one of supporting and receiving a removable platform such that the platform is capable of sliding forward a predetermined distance for placement under a toilet and sliding backward a predetermined distance and being completely removed for allowing such frame member to be placed in close proximity to a toilet such that such toilet is at least partially within such frame member. A rotatable lifting arm is operably connected to an upper end of such vertically disposed portion of such side members. A harness member, manufactured from a first predetermined material, is removably and operably connected to such rotatable lifting arm such that when such toilet is within such frame member the harness member is capable of being securably connected to such toilet such that the rotatable lifting arm may be implemented such that such toilet is lifted above floor level and can be lowered onto at least one of such platform and a floor by a user.
It is, therefore, one of the primary objects of the present invention to provide a tool to ease a user's installation or removal of a toilet.
Another object of the present invention is to provide a tool which permits a user to install or remove or reset a toilet while minimizing the strain placed on a user's back during such processes.
Still another object of the present invention is to provide a tool which enables a user to move a toilet from one location to another with ease.
Yet another object of the present invention is to provide a convenient tool upon which a toilet can be supported while a user prepares for installation of such toilet or prepares to transport such toilet to a new location.
In addition to the various objects and advantages of the present invention described with some degree of specificity above it should be obvious that additional objects and advantages of the present invention will become more readily apparent to those persons who are skilled in the relevant art from the following more detailed description of the invention, particularly, when such description is taken in conjunction with the attached drawing figures and with the appended claims.
