PRIORITY

[0001]The present invention claims priority under 35 USC sections 119 based on a provisional application with the Ser. No. 60/836,028 filed on Aug. 7, 2006.

FIELD OF THE INVENTION

[0002]The present invention relates to a revolving sun chair and lounge chair.

BACKGROUND OF THE INVENTION

[0003]Lounge chairs of various types are well known. Chaise lounge chairs are commonly available in three sections, two of which are adjustable for supporting the legs and the back at various positions. Most other chairs are unadjustable, but are commonly foldable for easy movement from place to place. Most such chairs have a tubular, aluminum frame with wood or aluminum armrests. The seat and back portions usually have a plurality of straps made from various materials extending between side frame pieces.

[0004]U.S. Pat. No. 4,639,036 is directed to sun shade apparatus for a chair or similar structure. The apparatus includes adjustment mechanisms for orienting the canopy sheet with respect to the chair for shade, for use as a tray or for stowage. The apparatus is easily attached to the chair with clamping mechanisms which are attached to the legs of a frame member.

[0005]The above mentioned chairs and lounges suffer from the defect that the above-mentioned shares and lounges cannot rotate. As a consequence, as the angle of the sun changes during the day, it is necessary for the user of the above-mentioned chairs and lounges to get up from the chairs and lounges and move the chairs and lounges as the angle of the sun changes during the day.

SUMMARY

[0006]The revolving sun chair of the present invention overcomes this problem by rotating so that the user of the revolving sun chair can easily change the position of the revolving sun chair as the angle of the sun changes during the day without getting out of the chair.

[0007]A revolving chair includes a swivel bearing affixed to the revolving chair to rotate the revolving chair.

[0008]The swivel bearing is connected to a upper plate, and swivel bearing is affixed to a lower swivel plate.

[0009]The revolving chair includes a lower swivel plate which is affixed to a leg with a L bracket, and the leg extends at an approximately 45.degree. angle with respect to the bracket.

[0010]In another style or another embodiment, the leg may form an approximate rectangle, and the swivel bearing is affixed to an upper swivel plate and the upper swivel plate is connected to the seat of the revolving chair.

[0011]The revolving chair includes a back being pivotably connected to the seat and includes a leg rest being pivotably connected to the seat.

[0012]The leg includes a leg extension.

DETAILED DESCRIPTION

[0021]FIG. 1 illustrates a side view of the revolving sun chair 100 of the present invention. The revolving sun chair 100 includes a back 102 which is shown as being rotated to an unfolded position by being rotated by a pivoting apparatus 128 and which may be an aluminum ratchet, a leg rest 104 which is illustrated as being in a folded position but can be rotated to an unfolded position by another pivoting apparatus 126 and is an aluminum ratchet, a seat 108 which is for the user to sit on and a support 106 to support the back 102 and which may be a frame covered with fabric, the leg rest 104 which is covered by fabric and the seat 108 which is also covered by fabric. The support 106 may be angled with respect to the vertical or substantially vertical (shown as the brace in the middle) and formed from aluminum or other suitable material. The support 106 is affixed by aluminum welding to an upper swivel plate 120 which may be formed from aluminum or any other suitable material. The upper swivel plate 120 is affixed to the swivel bearing 122 and may be formed from aluminum or any other suitable material. The swivel bearing 122 is rotatably affixed by a bolt going through to the upper swivel plate and the lower swivel plate so that the swivel bearing 122 can rotate for example by rotating 360.degree.. The swivel bearing 122 is affixed by a bolt going through the upper and lower swivel plates holding the ball bearings in a track in between to the lower swivel plate 118 and the upper swivel plate 120 which may be formed from aluminum or any other suitable material. The swivel bearing 122 may include a track and ball bearings for moving within the tracks.

[0022]The back 102 and the leg rest 104 can fold completely onto the seat 108 which may be formed from aluminum or other suitable material. The back 102, the leg rest 104 and the seat 108 is made of fabric connecting to the frame. The revolving sun chair 100 includes legs 116 and leg extensions 114 which extend outward to provide stability for the revolving sun chair 100 and are retractable. Once the leg extension 114 has been positioned by the user, a locking mechanism 130 which could be a threaded bolt which is threaded through an aperture through the leg 116, a spring-loaded button or other suitable device and which can lock the leg extension 114 with respect to the legs 116. The legs 116 are affixed by aluminum welding to the bracket 132 which is in turn aluminum welded to the lower swivel plate 118 and are formed by aluminum or another suitable material. FIG. 1 shows legs 116 and legs extensions 114 on one side of the lower swivel plate 118. However, additional legs 116 and legs extensions 114 could be located on the other side of the chair.

[0023]FIG. 2 illustrates that the back 102 has been rotated to a upright position. FIG. 2 illustrates that the leg rest 104 is folded onto the seat. FIG. 2 additionally illustrates that the leg extensions 114 are extended from the legs 116 and can be retracted into the legs 116. FIG. 2 illustrates that the support 106 which is shown as three braces on a side is aluminum welded and affixed to the upper swivel plate 120 and to the seat 108.

[0024]FIG. 3 illustrates that the back 102 has been rotated to an open position and locked. The back 102 may be set to a variable angle that is determined by the user of the chair 100. The back 102 can be moved to the desired angle and then held in position by a ratchet. FIG. 3 additionally illustrates that the leg rest 104 has been pivoted to a position with a small angle downward from the horizontal. The leg rest 104 can be placed in any position by the by virtue of the ratchet. FIG. 3 additionally illustrates the support 106 extending between the upper swivel plate 120 and the seat 108. The revolving sun chair 100 can rotate 360.degree. without the user getting out of the chair.

[0025]FIG. 4 illustrates a top view with the revolving sun chair 100 folded up. More particularly, the leg rest 104 has been folded onto the seat 108 and the back 102 has been folded onto the leg rest 104. The leg extensions 114 extend beyond the folded back 102 and can be retracted.

[0026]FIG. 5 illustrates the bottom of the revolving sun chair 100 and illustrates the lower swivel plate 118 which is affixed by aluminum welding to the bracket 132 which may be a L-shaped bracket formed from aluminum or other suitable material. The bracket 132 is affixed by aluminum welding to leg section 116. The angle of each of the legs 116 may be approximately 45 degrees. FIG. 5 additionally illustrates the leg extensions 114 extending from the legs 116. The leg extensions 114 can be retracted for storage or to move the revolving sun chair 100.

[0027]FIG. 6 illustrates an alternate embodiment for the legs. FIG. 6 illustrates that the lower swivel plate 118 is aluminum welded to the bracket 132 which may be an L-shaped bracket. The bracket 132 is aluminum welded to leg sections 140 which may be aluminum by aluminum welding. The leg sections 140 may be integral or affixed to a continuous leg 142 which may be aluminum or any suitable material. The continuous leg 142 may be square or rectangular or any other suitable shape.

[0028]FIG. 7 illustrates that the back 102 rotates between a fold up position and a folded down position and shows that the back 102 has been rotated upright. FIG. 7 illustrates that the leg rest 104 is folded. FIG. 7 additionally illustrates that the leg extensions 114 are extended from the legs 116 and can be retracted into the legs 116. FIG. 7 illustrates that the support 106 which is shown in the three braces on each side and which may be aluminum welded (tig or mig) is affixed to the upper swivel plate 120 and to the seat 108. FIG. 7 illustrates two braces. However, there are three braces on each side, making the total of six braces.
