4. The rotatable platform of claim 1 wherein the means for rotating comprises a pivot pin secured to the base.

5. The rotatable platform of claim 1 farther includes a spring interposed the upper and lower bodies to urge the fingers together.

6. The rotatable platform of claim 1 which further comprises a handle integrally formed with the platform and extending laterally outwardly therefrom to facilitate grasping of the platform.

7. The rotatable platform of claim 1 wherein the fingers removably retain a box top depicting a scene from which the jigsaw puzzle is to be assembled.

8. A rotating platform for a jigsaw puzzle box cover for positioning the cover in the line of sight of a user, the platform comprising: (a) a base having an upper or top surface and a lower surface or bottom surface; (b) means for rotating the platform secured to the bottom surface of the base; and (c) means for removably retaining a jigsaw puzzle box cover, the means for removably retaining mounted to the upper surface or top surface of the platform, the means for removably retaining comprises a pair of spaced apart fingers threadably mounted to the upper surface of the base, each finger having a lower body portion and an upper body overlying and coplanar with the upper body, the upper and lower bodies cooperating to provide a gap therebetween for removably seating an item therewithin.

9. The platform of claim 8, further includes a spring interposed the upper and lower bodies to urge the fingers together.

10. The platform of claim 8, which further comprises: a handle integrally formed with the platform and extending laterally outwardly therefrom to facilitate grasping of the platform.

DESCRIPTION OF THE PRESENT INVENTION

(6) Now, and with reference to the drawing, there is provided a rotatable platform in accordance herewith, generally denoted at 10. The platform comprises: (a) a base 12 having an upper or top surface 14 and a lower surface or bottom surface 16; (b) means 18 for rotating the platform secured to the bottom surface 16 of the base 12; (c) means 20 for removably retaining a box top cover which is mounted to the upper surface or top surface 14 of the platform 10. Optionally, means 24 for grasping of the platform may also be provided.

(7) With more particularity, and as shown in the drawing, the base 12 is a substantially planar member dimensioned to removably seat on a table top or other horizontal surface.

(8) The means 18 for rotating, preferably, comprises a bearing assembly 26 removably secured to the bottom surface 16. The bearing assembly contemplated for use herein is secured to the base by any suitable means, such as by press fitting, adhesive, or other means, such as suitable threaded fasteners or the like. Such bearing assemblies are well known and commercially available and generally comprise a two-piece housing having races in which ball bearings are disposed in one race and the other race is stationary.

(9) It is to be understood that, although in its preferred embodiment, the means for rotating comprises a bearing assembly, other means for rotating such as a pivot pin, or the like, can be used herein with equal efficacy.

(10) As shown in the drawing, the means 20 preferably comprises a pair of spaced apart fingers, 30, 32. The fingers 30, 32 are threadably mounted to the upper surface 14 of the base 12.

(11) Each finger comprises a lower body 34 and an overlying coplanar upper body 36. A gap 38 is provided between the upper and lower bodies to enable removable positioning of an item, such as a jigsaw puzzle box top 40 or the like in the gap.

(12) It is possible to provide a bias, such as a spring 41 interposed the upper and lower bodies to define a clamp for urging the bodies toward each other

(13) In order to facilitate rotation of the means 24 comprises a handle 42 integrally formed with the platform and extends laterally outwardly therefrom to facilitate rotation of the platform by grasping.

(14) In its preferred embodiment and as shown, the present device is used to removably position a box top or cover 40 such as that for a jigsaw puzzle 44 by inserting into the Bap 38 the cover 40 or whatever pictorial representation of the puzzle is provided.

(15) It is further contemplated that in the practice of the present invention, a recess 48 be formed in the upper surface 14 of the base 12 which can have emplaced therein indicia, such as an advertisement, printed piece, or the like.

(16) In use, a side 46 of the box top 40 is inserted into the gap 38 between the fingers 30, 32 at the opposite ends of the side in which it is securely retained. Thereafter, in assembling an item such as a jigsaw puzzle, users can easily rotate the box top of the puzzle via the handle enhance the ability to visually observe what the final assembly is to look like to facilitate the selection of the proper pieces for solving the puzzle.

(17) Thus, the present device provides a rotatable platform for facilitating the ability of more than one person to more rapidly solve the jigsaw puzzle.
