This drawing was designed for vacuum formed production. The type of production used could change the structure, but not the overall design. Injection molding would be less solid in appearance, but more structurally integrated.
The critical aspect of my invention are the angles of equilibrium in which the back corner of the ‘chair’ resides. These angles form the unique universal pitch that supports the ‘chairs’ at the approximate point of equilibrium. The feet of the ‘chair’ rest in the seat (A), or middle, of the mount. The adjacent slopes (i), designed at the angles required for equilibrium, provide support for the ‘chair’ at its base.
The angular ‘M’ design of the mount allows for strength and leverability, and minimizes slippage on the floor surface. The base (E), about 6 inches wide, tapers to around 5.5 inches at the top. The overall length is around 13 inches. The middle of the tool has a valley between two peaks, the seat of which approximates 90 degrees (A). Both slopes from this seat point are at specified angles that approximate the equilibrium point of the chair when tilted onto its back feet (B,C). Each of the slopes is a specified length to suit the minimum clearance of 7 inches of the low backed chairs. The distance from the ‘seat’, or 90 degree corner, is approximately 3 inches from the floor surface. (A to E)
The general size can vary to suit the application or height required, but the proportions and design will remain the similar. The tool needs to be rigid to support the weight and the correct angle of the ‘chair’.
The ‘chair’ is tilted forward slightly, and a ‘mount’ is placed under both feet at the rear of the ‘chair’. The steep angle (C) of the inner slope faces the front of the ‘chair’. Then the ‘chair’ is tilted backwards into the equilibrium position. If the sofa is large, each side is lifted separately and a ‘mount’ placed under each of the rear feet. The rear feet of the ‘chair’ now sit in the right angled seat of the ‘mount’. The ‘chair’ is then tilted back to the point at which it comes to rest, with its base a few inches off the floor. This will be the approximate position of equilibrium, allowing the ‘chair’ to sit securely in this state.
To remove, simply tilt forward again and remove the two mounts.
From the description above, a number of advantages of my ‘chair and sofa floor mount’ become evident whereby:
Accordingly the reader will see that, based on the specification details set out above, this invention provides a unique solution to a common household floor cleaning problem.
While the above description contains specifics, these should not be construed as limitations to the scope of the invention, but as exemplifications of the presently preferred embodiments thereof. Other variations are possible within the principle of this invention. For example, the product could be adapted for specific types of chairs. Recliners have a narrow steel frame base. The design could be tailored to be narrower with an indent for the frame to fit into.
Thus the scope of the invention should be determined by the appended claims and their legal equivalents, and not by the examples given.
