The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of painting machines of existing art and more specifically relates to manually maneuverable painting carts.
Painting supplies used for larger projects such as roadways and parking lots are very heavy. Carrying all the supplies needed for painting is not feasible. Often a large compressor tank is coupled with a motor to draw paint from a reservoir. The paint then travels through a heavy rubber hose to a paint gun. Paint is very heavy, and the volume of paint needed to complete a task may weigh much more than a person can sustainably carry. Most painting professionals have difficulty in carrying the paint and associated accessories.
The device that painting professionals typically use have wheeled carts so the paint and associated accessories may be transported for convenience. Many of these painting supply transport carts have two, three, or four wheels. Often the carts also have an attachment to mount a paint gun such that the nozzle will point at a surface to be painted. The two wheeled carts prove difficult to paint straight lines, thus the advent of the three wheeled cart. While the three wheeled carts may provide a means of painting straight lines, the wheel must be retractable for maneuverability. When the wheel is retracted, the paint cart is not stable and will tip if unattended. The four wheeled carts have sufficient storage capacity and stability for carrying paint and associated supplies. However, with four freely rotatable wheels, the four wheeled cart does not provide the ability to reliably paint straight lines. A suitable solution is desired.
U.S. Pat. No. 7,237,783 to Joseph Kieffer relates to an accessory cart for striping pavement and other surfaces. The described accessory cart for striping pavement and other surfaces includes an accessory cart having a J-shaped frame for removable mounting of a spray gun to convert a conventional airless paint sprayer into a line striper to paint lines on parking lots, curbs, warehouse floors and other pavement surfaces, and which can alternately be used in conjunction with a traditional line striper in cramped spaces or between parked cars, and which is easily converted from a 3-wheeled device to a 2-wheeled device for painting curved lines, and which permits adjustable positioning of the spray gun at a desired location on the cart to optimize the spray pattern in a particular application.
In view of the foregoing disadvantages inherent in the known manually maneuverable painting carts art, the present disclosure provides a novel hand operated painting cart apparatus. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide an efficient and effective hand operated painting cart apparatus and method.

These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.
The figures which accompany the written portion of this specification illustrate embodiments and methods of use for the present disclosure, a hand operated painting cart apparatus, constructed and operative according to the teachings of the present disclosure.
The various embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
As discussed above, embodiments of the present disclosure relate to a manually maneuverable painting carts and more particularly to a hand operated painting cart apparatus as used to improve the existing manually maneuverable painting cart art.
Generally, the hand operated painting cart apparatus provides a functional manually maneuverable painting cart having four base wheels and, a fifth retractable wheel. The hand operated painting cart apparatus includes a wheeled base with an attached frame capable of carrying painting supplies. A spray-holster is configured to attach a paint gun to the frame for painting a surface. A handle is attached to the frame that includes a pair of two hand triggers. The first hand trigger is attached to a wire that is attachable to the paint gun. When the first hand trigger is activated, the wire is retracted, and the paint gun is activated. Decompressing the first hand trigger to its normal state will deactivate the paint gun. The second hand trigger is attached to the fifth wheel assembly. The second hand trigger is configured to retract the wheel of the fifth wheel assembly and disengage the wheel from the ground. The fifth wheel assembly comprises opposing upper and lower platforms pivotably connected by a retaining member. The lower platform has an attached wheel. The lower platform pivots such that the wheel is either engaged with the ground, and alternatively, retracted and disengaged with the ground. A first-abutment member is connected to the upper-platform and is configured to support the lower platform when the wheel is engaged with the ground. The second hand trigger is configured to retract a second wire that pulls a pivot arm. The pivot arm is pivotably attached to the lower platform and abuts with a back-abutment member attached to the upper-platform. When the second wire is retracted, the pivot arm disengages with the back-abutment member, allowing the lower platform to pivot and disengaging the wheel from the ground.
