360-DEGREE SWIVEL CUSHION
A 360 degree swivel cushion. The cushion includes a swivel ball seat configured between a swivel plate and a base plate. The steel balls are positioned within the swivel ball seat so that the cushion can slide on circular tracks configured on a base of the swivel plate. A cover is disposed on the swivel plate, and the cushion can rotate 360 degrees on top of the base plate.
(a) Field of the Invention
A 360 swivel cushion of the present invention relates to a swivel cushion, and more particularly to a swivel cushion capable of rotating 360 degrees and sliding in 4 directions. A user can arbitrarily rotate and shift position of the cushion, and therefore suited for usage by an office worker who has to sit for long periods, and for those aged and weak patients for whom getting around is inconvenient or as a cushion seat in automobile.
(b) Description of the Prior Art
Accordingly, a common cushion has an extensive range of applications. In day-to-day life, the cushion can be placed on a chair, on a seat of an automobile or on sickbeds. However, because a conventional cushion is structured so as to be fixed in position, and therefore impossible to rotate, immense inconvenience results when aged and weak or women and children for whom getting around is inconvenient or bedridden patients wish to shift position of their bodies, turn over or get down from bed, As a consequence, there is a wanting need for advancement in cushion design.
SUMMARY OF THE INVENTIONA primary objective of the present invention is to utilize a number of steel balls reposed within a swivel ball seat, and therewith slide on circular tracks configured on a base of a swivel plate, thereby carrying along a cushion and rotating and sliding on a base plate thereof, and thus providing a cushion with functionality to arbitrarily rotate 360 degrees and slide in four directions, enhancing and providing greater convenience to everyday life.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

In conclusion, the 360 degree swivel cushion of the present invention utilizes the swivel ball seat 2 disposed between the base plate 1 and the swivel plate 3, to actualize 360 degree rotation and arbitrary change in direction, thereby enhancing and providing greater convenience to daily life of chair-ridden persons, aged and weak, women, children and bedridden patients for whom getting around is inconvenient.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
Claims
1. A 360 degree swivel cushion, comprising:
- a base plate having a perforation at a center thereof;
- a swivel ball seat comprising concentric rings of varying diameters that are interconnected by connecting portions, upon which is configured a number of ball orifices, within which steel balls are embedded therein, a central screw hole is positioned at a center of the swivel ball seat;
- a swivel plate comprising a base, the base of the swivel plate having concentric tracks of varying diameters that are interconnected by radial connecting portions, thereby enabling the steel balls to roll within the tracks, a screw hole is further defined in a center of the base of the swivel plate;
- a foam rubber is adhered on top of the cushion;
- a cover covers the top of the foam rubber and exposed portions of the swivel cushion; and
- a screw passes through the perforation of the base plate and the central screw hole of the swivel ball seat and is secured to the screw hole of the swivel plate, so that the swivel ball seat secured to the cushion is rotatable by 360 degrees with respect to the base plate.
