     FIELD OF THE INVENTION 
     This invention relates to improved methods and apparatus concerning mounting chairs. 
     BACKGROUND OF THE INVENTION 
     The general concept of mounting a chair onto a device which swivels is known in the art. For example, U.S. Pat. No. 7,328,952 to Guerrini discloses a saddle 12 which rotates with respect to a platform 14 about a vertical axis. (Guerrini &#39;952, col. 2, Ins. 37-46; FIG. 1). Guerrini &#39;952 further discloses the mounting of a beach chair 24 by use of mounting clips 20 to the saddle 12, thereby permitting rotation of the chair 24 with reference to the platform 14. (Id.) A friction reducing mechanism 96, including ball bearings 86, facilitate rotation of the saddle 12. (Guerrini &#39;952, col. 3, Ins. 53-55; FIG. 1, and FIG. 8). Guerrini states that an annular seal 104 with an outwardly extending flange 106 prevents foreign matter, such as dirt, dust, and sand, from reaching bearings 86 thereby making bearings 86 maintenance free. (Guerrini &#39;952, col. 3, In. 62-col. 4, In. 2; FIG. 1 and FIG. 8). Another patent to Guerrini, U.S. Pat. No. 7,325,875, discloses mounting a seat 12, onto a saddle 94 which rotates with respect to a platform 96, and an annular seal 194 to prevent dirt from reaching bearings 178. (Guerrini &#39;875, col. 3, Ins. 39-47; col. 4, In. 65-col. 5, In. 5; FIG. 3). A third patent to Guerrini, U.S. Pat. No. 6,315,360 discloses fastening a chair 22 to a swivel apparatus 10 which includes a top ring 56 which freely rotates with respect to a bottom ring 52, ball bearings 62, and a dust cover 64 atop ring 56 to prevent dirt from fouling bearings 62. (Guerrini, &#39;360 patent, col. 1, In. 66-col. 2, In. 5; col. 2, Ins. 30-42; FIGS. 1-3). 
     Each of the above Guerrini patents indicates that it prevents dirt or sand from reaching and/or fouling ball bearings. However, practically speaking, because the Guerrini devices can swivel, it is very difficult, if not impossible to prevent sand or dirt from reaching the ball bearings. This is especially true if the Guerrini devices are taken to a beach environment, where it is likely that sand will reach the ball bearings. When sand reaches the ball bearings it will make it more difficult and/or impossible for the Guerrini devices to swivel, thus effectively ruining operation of the devices.

     Balls  28   a  and  28   b  are typically identical. Although only balls  28   a  and  28   b  are shown, typically there would be thirty to sixty balls, each identical to ball  28   a  or ball  28   b , and each placed between walls  26   a  and  26   c , and on the curved surface  26   b , and would sit between the circular disk  8  and the circular disk  26 . 
     The apparatus  1  can be used as a base for any product requiring a three hundred and sixty degree swivel action. The apparatus  1  has a top swivel assembly including brackets or clips  10  and  12  to accommodate existing bench and lawn chairs. The clips  10  and  12  shown will hold and locate the specific chair being used. 
     The apparatus  1  can be made in different sizes, and other changes can be done to accommodate weights and mounting requirements. The configuration shown in  FIGS. 1A-3  (amount of parts) can be changed to reduce production costs and total assembly weight. The apparatus  1  can be made to be portable or stationary. 
     Typically, the apparatus  1  is portable with the chair or chairs being attached at a final location. In at least one embodiment, the apparatus  1  will be light in weight to allow easy transportation. 
     The apparatus  1  also allows cleaning of sand (from beach) or any similar type materials or debris to prevent swivel function from being disturbed.

The central opening  212   a  may be circular and may have an inner diameter, D10 shown in  FIG. 13A , which is slightly greater than the outer diameter D7, shown in  FIG. 11A , of the body portion  202   d  of the bolt  202 , which allows the body portion  202   d  to be inserted into the opening  212   a  and to snugly fit therein. The openings  212   b - 212   e  may be circular and may each have a diameter of D11, which may be about one inch, as shown in  FIG. 13A . 
     Each of the first, second, third, and fourth sets of slots or openings  214 ,  216 ,  218 , and  220 , may be elongated in the direction of a width W3 of the mounting device  206 , i.e. each slot may be substantially longer in the direction of the width W3 than in the direction of a length L2 shown in  FIG. 13A . For example, each slot  214 ,  216 ,  218 , and  220  may be one quarter inch in size in the direction of length L2, and one inch in size in the direction of the width W3. This elongated structure and arrangement is particularly suited for receiving a strap in one or more of the slots  214 ,  216 ,  218 , and  220  to secure a leg of a chair to the mounting device  206 . In at least one embodiment, a solid triangular prism structure of set  222  is provided for each of the slots  214 , and a solid triangular prism structure of set  224  is provided for each of the slots  216 . However, solid triangular prism structures, in at least one embodiment, are not provided for slots  218  and  220  to allow different sized chairs to be mounted more easily, i.e. the lengths of chairs, with length parallel to L2, do not have to be at certain fixed intervals (such as two feet, two feet and two inches, two feet and four inches) but rather the lengths of chairs can fit within broad parameters (such as any chair length between two feet and two feet four inches, for example). 
     The plurality or set of slots  214  includes slots  214   a  and  214   b . The plurality or set of slots  216  includes slots  216   a  and  216   b . The plurality or set of prism structures  222  includes structures  222   a  and  222   b . The plurality or set of prism structures  224  includes structures  224   a  and  224   b . The plurality of structural walls  228 , includes walls  228   a ,  228   b ,  228   c ,  228   d ,  228   e ,  228   f ,  228   g ,  228   g ,  228   i ,  228   j ,  228   k ,  228   l ,  228   m , and  228   n . Each of walls  228   a - 228   n  is perpendicular or substantially perpendicular to the member  208 . The peripheral wall  210   b  of the disc member  210  is also perpendicular or substantially perpendicular to the member  208 . The ring  226   a , and the members  226   b - e  are also perpendicular or substantially perpendicular to the member  208 . The disc member  210  has an inner diameter D13, which may be eighteen inches, and which is sized to be slightly greater than an outer diameter D18 of the second disc device  240  shown in  FIG. 19A , so that the disc member  210  can fit around the second disc device  240  providing a snug fit. 
     The ring  212   a  and the members  226   b - e  have a perpendicular height H4, with respect to the surface  210   c  of the member  210 , which is less than the perpendicular height H3 of the inner surface  210   d  of the peripheral wall  210   b . The height H3 may be fifteen sixteenths of an inch and the height H4 may be six sixteenths of an inch, in at least one embodiment. The dimensions, such as H3 and H4 are configured so that the bottom peripheral edge  210   f , shown in  FIG. 15A , of the disc member  210  will not contact a top surface  262   a  of the base  260  shown in  FIG. 20A , when the mounting device  206  is arranged with respect to the base  260  as shown in  FIG. 9 . In  FIG. 9 , the inner surface  210   c  (shown in  FIG. 15A ) of the disc member  210  rests on the balls  232  (shown in  FIG. 8 ), the bottom peripheral edge  210   f  does not contact the base  260 , and a top peripheral edge  2242   a  (shown in  FIG. 19A ) of the second disc device  240  does not contact the inner surface  210   c  of the disc member  210 . Thus when the disc member  210  rotates with respect to the base  260 , the bottom peripheral edge  210   f  of member  210  (shown in  FIG. 15A ), and the top peripheral edge  242   a  of disc device  240  (shown in  FIG. 19A ) move freely. This configuration allows the disc member  210  and the mounting device  206  to rotate more freely with respect to the disc device  240  which is fixed to the base  260 . Note also that the ring  226   a  (shown in  FIG. 15A ) does not contact the top surface  254   a  of the ring  254  or the first disc device  234 , as shown by  FIGS. 23A and 23B . Rather the ring  226 A which encircles the ring  253 , in the configuration of  FIG. 5 , is slightly above the first disc device  234  so that ring  226   a  and the first disc device  234  do not frictionally engage, in at least one embodiment. 
     Referring to  FIG. 10  in operation the mounting device  206  can rotate in the clockwise direction C3 or in the counterclockwise direction C4 with respect to the combination of the second disc device  240  and the base device  260 .

FIG. 23B  shows a cross section of part of an assembled apparatus  201  of  FIG. 9 , along a line passing through a center of the bolt  202  of  FIG. 11A  in the center of the apparatus  201  of  FIG. 9 , with the first disc device  234  of  FIG. 18A  in an orientation such that a cross section of two bearing balls  232  can be not be seen. 
     Referring to  FIG. 23A , the inner surface or bottom surface  210   c  of the disc member  210  of the mounting device  206  is shown resting simultaneously on a ball of plurality of balls  232  on the left and a ball of plurality of balls  232  on the right of  FIG. 23A . In at least one embodiment the inner surface  210   c  rests and/or is supported by all of the plurality of balls  232  at the same time, such as by sixteen balls  232  shown in  FIG. 5 , at the same time. At the same time, the balls  232  sit on the second disc device  240 . The inner surface  210   c  of the disc member  210  also, simultaneously, rests on spacer  230 . The spacer  230  rests on bearing  256  and inner ring  257 . Bearing  256  and/or ring  257  rotate with respect to ring  255 . Ring  255  is fixed with respect to ring  253  which is fixed to ring  254 , which is fixed to second disc device  240 . Bearing  256  rotates on top of or within ring  256   a . Rings  254 ,  253 ,  255 , and  256   a  are fixed to the second disc device  240 . Thus, in at least one embodiment, the inner surface  210   c  only rests simultaneously on balls  232  and on spacer  230  while the mounting device  206  rotates with respect to the base device  260  (and second disc device  240 , which is typically molded together as one piece with base device  260 ), which results in smooth rotation of mounting device  206  with respect to the combination of second disc device  240  and base device  260 . 
     In  FIG. 23A , the first disc device  234  rests on the inner peripheral or circular wall  244  and within the outer wall peripheral or circular wall  242 , and the first disc device  234  simultaneously rests on the inner circular wall  248  and on the ring  254 . The first disc device  234  can be rotated with respect to the second disc device  240  which may be integrated with the base device  260 , and with respect to the mounting device  206 . Each of the balls  232  lies in an opening of the plurality of openings  235  of the first disc device  234 . 
     The peripheral wall  210   b  of the disc member  210  of the mounting device  206 , in at least one embodiment, does not contact the wall  242 , and the inner surface  210   c  does not contact the edge  242   a  of the wall  242 , but rather only contacts the balls  232  and the spacer  230  during rotation, also resulting in smooth rotation of mounting device  206  with respect to the combination of second disc device  240  and base device  260 . 
     In  FIG. 23B , the first disc device  234  has been rotated with respect to the disc member  210  of the mounting device  206  and with respect to the second disc device  240  and the base device  260 , so that the indentations  236  in the first disc device  234  can be seen. In at least one embodiment, water can be supplied into openings  212  of the mounting device  206 , such as into openings  212   c  and  212   e  shown in  FIG. 23B . The water will then flow into a cavity between the disc member  210  and the first disc device  234 . Thereafter the water flows through the indentations  236  and openings  239  shown in  FIG. 23B , through spaces between the balls  232  and the openings  235  shown in  FIG. 23A , or through further optional openings which may be supplied in the first disc device  234 , into a cavity between the first disc device  234  and the second disc device  240 . The water thereafter flows out of the swivel device or apparatus  1 , through openings, such as openings  249   g ,  251   b ,  251   c ,  249   c , and corresponding aligned openings  264   g ,  266   d ,  266   b , and  264   c , shown in  FIGS. 23A and 23B . Additional openings, not shown may be provided in the first disc device  234  between walls  248  and ring  254  to allow flow out of openings  251   b  and  266   d , and  251   c , and  266   b . The flow of water in the manner described cleans dirt, debris, and sand out of the cavity between the first disc device  234  and the second disc device  240  and away from the balls  232  and away from the spacer  230  to allow for continued smooth rotation operation of the mounting device  206  with respect to the combination of the second disc device  240  and the base device  260 .
