Abstract

A 360 degree revolving cushion comprises: a base plate 1 having a central screw receiving hole 11; a circular web-like seat member 2 having a number of apertures 21 in which ball-bearings 22 are embedded and a central screw hole 23; a swivel plate 3 provided with a plurality of concentric circular tracks 31 in which the ball bearings 22 are received and a central screw hole 32; and a screw (A) which, in use, couples together the base plate 1, the bearing seat 2, and the swivel plate 3. A cushion 4 is attached to the swivel plate 3 and a foam rubber 5 is placed over the cushion. The foam and cushion layers are wrapped in a cover 6. The swivel cushion can be placed on an existing chair, e.g. vehicle seat, or bed to enable weak patients or the elderly to move around or get up out of the chair or bed.

j 2407028 360-DEGREE SWIVEL CU51oN

BACKGROUND OF THE INVENTION

(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.

0 (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 INVENTION

A 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 s embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a schematic drawing according to the present invention.

FIG. 2 shows an exploded elevational view according to the present invention.

0 FIG. 3 shows a partial cross sectional view according to the present invention.

FIG. 4 shows an embodiment according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED

EMBODIMENTS

Referring to Figs. 1 and 2, which depict a 360-degree swivel cushion of the present invention comprising and constructed to include a base plate 1, a swivel ball seat 2, a swivel plate 3, a cushion 4, a foam rubber 5 and a cover 6. A perforation 11 is defined in a center of the base plate I for a screw A to pass therethrough. The swivel ball seat 2 comprises a circular web-like seat, upon which is configured a number of ball orifices 21. A steel ball 22 is embedded in each of the ball orifices 21; thereby 24 steel balls 22 are distributed on top of the web-like swivel ball seat 2. The swivel plate 3 is configured so as to lie on top of the swivel ball seat 2. Three circular tracks 31 of variant diameter are configured on a base of the swivel plate 3, thereby enabling the steel balls 22 to separately repose in the tracks - 2 31. A screw hole 32 is defined in a center of a base of the swivel plate 3, and, upon the swivel ball seat 2 being disposed between the base plate 1 and the swivel plate 3, the screw A is made to pass through the perforation l l of the base plate 1 and a central screw hole 23 of the swivel ball seat 2 and thereat screwed down within the screw hole 32 of the swivel plate 3.

Referring to FIG. 3, which shows the cushion 4 fixedly adhered on top of the swivel plate 3. The foam rubber 5 is placed and adhered on top of the cushion 4, and the cover 6 is then made to fully cover the foam rubber thereon. The cover 6 completely wraps round a bottom of the 360-degree swivel cushion, and is designed for easy taking off to facilitate cleaning thereof.

Referring to FIG. 4, which depicts the 360 degree swivel cushion of the present invention completely assembled, and thereby actualized for 360 degree rotation and slippage in 4 directions, whereby the swivel ball seat 2 is configured to carry along the swivel pan 3, the cushion 4, the foam rubber 5 and the cover 6, and thus realize rotating on top of the base plate I thereof.

In conclusion, the 360 degree swivel cushion of the present invention utilizes the swivel ball seat 2 disposed between the base plate l 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 - 3 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. - 4

Claims

What is claimed is: 1. A 360 degree swivel cushion, comprising: a base

plate, a center of which is defined a perforation; a swivel ball seat, designed as a circular web-like seat, upon which is s configured a number of ball orifices, within which steel balls are embedded, a central screw hole is further defined at a center of the swivel ball seat; a swivel plate, on a base of which are configured circular tracks of variant diameter, thereby enabling the steel balls of the swivel ball seat to lo separately repose in the tracks and slide therein, a screw hole is further defined in a center of a base of the swivel plate; a cushion, a base of which is joined to the swivel plate; a foam rubber, which is adhered on top of the cushion; a cover, which is placed on top of and covers the foam rubber, and designed to completely wrap round a bottom of the 360 degree swivel cushion; from aforementioned components the 360 degree swivel cushion is thereby constructed utilizing a screw to pass through the perforation of the base plate and a central screw hole of the swivel ball seat and thereat is screwed down within the screw hole of the swivel plate, thereby the swivel ball seat is configured to carry along the cushion, and thus realize 360 degrees rotation on top of the base plate thereof.

Amendments to the claims have been filed as follows: 1. A 360 degree swivel cushion, comprising: a base plate having an aperture at its centre; a swivel ball seat in the form of a planar circular web-like seat, having a plurality of ball orifices, steel balls embedded within the ball orifices by embedding means comprising ball cages secured in the ball orifices and extending above and below the plane of the ball seat, the ball cages retaining the steel balls in the ball orifices of the swivel ball seat; the swivel ball seat having a central screw hole at its centre; a swivel plate, on a lower surface of which is formed ' ' circular tracks of a plurality of diameters such that the ' '' steel balls of the swivel ball seat separately contact the < tracks and move therein; ,,; the lower surface of the swivel plate having a screw hole at its centre; '<' a cushion, the lower surface of which is joined to the t< swivel plate; a foam rubber part, which is adhered to the top of the cushion; a cover, which is placed on top of and covering the foam rubber part, and designed to completely wrap round a bottom of the 360 degree swivel cushion; the 360 degree swivel cushion further comprising a screw which passes through the aperture of the base plate and the central screw hole of the swivel ball seat, and is screwed to the screw hole of the swivel plate, such that the swivel ball seat is configured to carry the cushion, and thus allow 360 degrees of rotation on top of the base plate. -b
