For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the invention.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
The same reference numerals refer to the same parts throughout the various Figures.
With reference now to the drawings, and in particular to
The present invention, the rotatable book stand system 10 is comprised of a plurality of components. Such components in their broadest context include a lower base plate, an upper base plate, a roller bearing assembly, and a support member. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
First provided is a lower base plate 14. The lower base plate is formed in a square configuration. The lower base plate has a first upper surface 16. The first upper surface is in a flat horizontal configuration. The first upper surface has a first lower surface 18. The first lower surface of the first upper surface is in a flat horizontal configuration. The lower base plate has lower edges 20. The first lower surface is positionable on a recipient surface. The lower base plate is from 7 inches to 8 inches on each side. The lower base plate has a thickness of from 0.5 inch and 1.0 inch. The lower base plate has a midpoint. The lower base plate is fabricated of a rigid material.
An upper base plate 22 is provided. The upper base plate is formed in a square configuration. The upper base plate has a second upper surface 24. The second upper surface is in a flat horizontal configuration. The second upper surface has a second lower surface 26. The second lower surface of the second upper surface is in a flat horizontal configuration. The upper base plate has upper edges 28. The second lower surface is positioned above the first upper surface. The upper base plate is from 11 inches to 13 inches on each side. The upper base plate has a thickness of from 0.5 inch and 1.0 inch. The upper base plate has a midpoint. The upper base plate is fabricated of a rigid material.
Provided next is a roller bearing assembly 30. The roller bearing assembly has a third upper surface 32. The third upper surface is secured to the second lower surface. The roller bearing assembly has a third lower surface 34. The third lower surface is secured to the first upper surface. The roller bearing assembly has a circular configuration. The roller bearing assembly has a midpoint. The midpoint is vertically aligned with the midpoint of the upper base plate and the midpoint of the lower base plate. A pivot pin 35 rotatably couples the upper base plate to the lower base plate. The roller bearing assembly has a diameter of from 7 inches to 9 inches. The roller bearing assembly has a plurality of spherical rollers 36 adapted to allow rotational movement of the upper base plate with respect to the lower base plate. The entire lower base plate always stays located beneath the upper base plate.
The upper base plate has an area between 80 percent and 90 percent greater than the lower base plate which has been found to provide maximum stability during use.
Further provided is a support member 38. The support member is fabricated of a single sheet of metal. The support member has a horizontal top section 40. The support member also has primary and secondary short bottom sections 42, 44 and primary and secondary long intermediate sections 46, 48. The support member has a horizontal centerline extending there through. The top section has a length of from 1 to 2 inches. The short bottom sections have lengths of from 2 to 3 inches. The long intermediate sections have lengths of from 9 to 10 inches. The support member forms upper junctures 50, 52. In this manner obtuse angles are formed between the top section and the long intermediate sections. The support member forms lower junctures 54, 56. In this manner 90 degree angles are formed between the short bottom sections and the long intermediate sections. Each lower junction has opposed lower ends. The upper junctures are parallel with and equally spaced from the midpoint of the roller bearing assembly. The lower junctures are parallel with and equally spaced from the midpoint of the roller bearing assembly. The long intermediate sections are between 15 and 20 degrees from the vertical. The support member is adapted to support a first book in contact with the primary long intermediate section and the primary short bottom section. The support member is further adapted to support a second book in contact with the secondary long intermediate section and the secondary short bottom section.
Provided last are fasteners 60. The fasteners extend through the lower junctures coupling the support member to the upper base plate at locations equally spaced from the centerline and the opposed lower ends of each lower junction.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
The present application is a continuation-in-part of application Ser. No. 14/249,485 filed Apr. 10, 2014, the priority Of which is claimed and the subject matter of which is incorporated herein by reference.
