Full Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to beach gear transporters, and more particularly, to a wheeled beach gear transporter that converts to provide storage, chairs, table and shade. 
     2. Description of the Related Art 
     Several designs for wheeled beach gear transporters have been designed in the past. None of them, however, provide for a device that provides all necessary beachgoer accessories comprising, inter alia, chairs, a table, storage and shade that assemble together in a compact manner to form a wheeled package for easy transport to and from the beach or other recreational site. 
     Applicant believes that the closest reference corresponds to U.S. Pat. No. 6,131,925 issued to Weldon. However, it differs from the present invention because the Weldon invention requires straps to hold the components of the device together during transport, only provides a single chair and does not provide a table surface. Furthermore, the Weldon invention is not readily compatible with larger diameter wheel as is beneficial for mobility on soft ground such as sand. The Weldon invention also does not provide for a stable mounting feature for a sunshade which is desirable for use on firmer ground or in windy conditions. 
     The present invention solves these problems by providing in a preferred version a compact and large wheeled device that easily converts to provide two chairs a table, an umbrella stand and storage container. Additionally, the configuration of the present invention does not require the use of straps while in its transport mode but instead relies on gravity to hold the storage container securely on the device. 
     In U.S. Pat. No. 5,269,157, Ciminelli describes an insulated beach box which is adapted to be wheeled or slid over terrain to reach a desired beach location. The beach box has a pivotally connected back which may be used as a handle when moving the box and as a seat back when sitting upon the box. The back includes a flexible member with pockets for storing personal items. While Ciminelli suggests that there is a need for a device to facilitate carrying utilitarian items to and from the beach, his invention provides for an insulated box and a seat/chair only. Ciminelli suggests that a beach umbrella may be stuck into the sand and clamped to the seat back to shade the seat&#39;s occupant. However, Ciminelli does not disclose how the umbrella is carried to the beach and no provision for attachment to the beach box is described. During transit, Ciminelli suggests that miscellaneous beach items which can fit between the back and top of the beach box may be held on with a flexible strap. 
     Carlile, in U.S. Pat. No. 4,865,346, describes a collapsible cart, held together by the frictional engagement of its components and quickly disassembled, which may be used to carry articles to the beach. The cart has a pivotally attached bottom shelf, which may be locked into position with a set of folding braces, for carrying a cooler chest. The cart is supported in an upright position by a rest attached to the edge of the shelf when the shelf is in its locked position. A picnic basket with folding shelf is attached to the cart above the cooler chest. Carlile provides for a single umbrella holder on one of the cart&#39;s side arms and beverage holders on the other side arm. Additional bracket arms support one or more folding chairs. On the rear of the cart, a auxiliary storage bag is removably attached. 
     A beach caddie is described by Higson in U.S. Pat. No. 4,703,944 which incorporates a chair rack and platform assembly, and, when used in a horizontal position at the beach, provides a beach table. The beach caddie apparently provides for the transportation of an umbrella and fishing poles as well as for their storage once at the beach. A topmost hinged section attached to the vertical members may be rotated at a right angle to the vertical members so that shafts of umbrellas and fishing poles may be placed through orifices therein. Such shafts rest upon the “upper cross-member  6 ” of the caddie although it is not clear whether the shafts engage the holes in the cross-member. It is also not clear what keeps the topmost hinged section from working against and flexing the fishing poles and/or umbrella shaft. The table surface of the caddie has orifices sized to hold umbrella and fishing pole shafts (presumably in an upright position for use) and orifices to hold drinks. Hook and loop fasteners secure the movable members when the caddie is used as a table at the beach. 
     Bonewicz, in U.S. Pat. No. 4,887,837, describes a carrier for transporting objects to the beach. Bonewicz describes a relatively straight-forward hand cart having a platform which either folds up parallel to the main frame or rotates perpendicularly to form a carrying surface. The platform has locking braces on its underside which engage the side rails to support the weight of the items being transported. In one embodiment the cart has a “cup-like” member located near the lower end of a side frame and a hook-like clasping member mounted higher on the same side frame. An umbrella may be attached with its top end in the cup-like receptacle and the hook-like element encircling its lower end. It is not clear what happens when the umbrella diameter exceeds the size of the hook-like member. The cart is further provided with a picnic basket or bag which may be mounted between the two frame members to carry additional articles. In a preferred embodiment, a hollow bag may be slipped over the upright frame and held by a strap to the handle. In this embodiment, the hook-like member and the cup-like member are not used and an umbrella can not be carried on the cart. Like Ciminelli an elastic cord may be stretch between the upright frame and the platform to restrain items placed on the platform. 
     While these devices of the prior art address some of the needs of a typical beachgoer, none of the devices address the problems which are solved by the present invention and, in particular, perhaps the most frequently encountered problem of beach activity is not met. No known prior art provide for a beach transport device that works well on both hard and soft surfaces, holds a storage element by gravity reducing the need for straps while imparting stability to the device, provides multiple seats and a table and can hold an umbrella in impenetrable soil. 
     Other patents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings, where a version the present invention is generally referred to with numeral  10  in  FIG. 1  (sometimes referred to as the device), it can be observed that it basically includes a wheel assembly  100 , a yoke assembly  200 , a chair assembly  300 , a case assembly  400  and optionally an umbrella  216 . 
     Two wheel assemblies  100  are preferably present, one on each side of the yoke assembly  200 . A case assembly  400  is supported by the yoke assembly  200  and situated between said wheel assemblies  100 . Each wheel assembly  100  has affixed to it a chair assembly  300 . 
     The device  10  as shown in  FIG. 1  is in transport mode. In transport mode generally each of the two chair assemblies  300  are affixed to one of each of the two wheel assemblies  100 . Each of the two wheel assemblies  100  are rotatably attached to the yoke assembly  200 . The case assembly  400  rests in place by gravity over the yoke assembly  200 . An umbrella  216  rests atop the case assembly  400  and the yoke assembly  200 . When the device is in transport mode it can be easily moved or stored. 
     Now referring to  FIG. 2  where an exploded perspective view of the version of the invention demonstrated in  FIG. 1  is shown to comprise, inter alia, the wheel assembly  100 , the yoke assembly  200 , the chair assembly  300  and the case assembly  400 . 
     Each of said wheel assemblies  100  is further comprised of, inter alia, a wheel  102 , an axle  104 , a disk  106 , a bore  108 , a rib  110 , a cup holder  112 , a fastener  114 , a seat  116 , a flange  118  and a seat  136 . 
     Said yoke assembly  200  is further comprised of, inter alia, a yoke  202 , a receiver  204 , a receiver  206 , a shaft  208 , a rest  210 , a handle  212  and a fork  214 . 
     Each of said chair assemblies  300  is further comprised of, inter alia, a back  302 , a hinge  304 , a hinge  306  and a support  308 . 
     Said case assembly  400  is further comprised of, inter alia, a strap  402 , a panel  404 , a frame  406 , a case  408 , a seam  410 , a seam  412 , a saddle  414  and a panel  416 . 
     Still referring to  FIG. 2  where the invention is shown in an exploded view it can be understood that one each of said wheels  102  are positioned on each side of said yoke  202 . Between each of said wheels  102  and said yoke  202  is a disk  106 . Said disk  106  optionally has a multiplicity of cup holders  112  around the periphery of the disk  106  that are dimensioned to accept standard sized drinking cups. Said disk  106  optionally has a rib  110  integrally formed or affixed to the underside of the disk  106  to lend structural rigidity to the disk  106 . 
     When the device  10  is in a transport mode the disk  106  is nested onto the bottom side of the wheel assembly  100 . The chair assembly  300  is nested onto the top side of the wheel assembly  100 . The bore  108  through the disk  106  is rotatably and removably affixed to the axle  104  on seat  136 . A fastener  114  attaches each wheel assembly  100 , chair assembly  300  and disk  106  to the axle  104 . The yoke assembly  200  at each of the forks  214  is held by gravity onto the axle  104  between flange  118  and seat  136 . A handle  212  is connected to the yoke  202  via a shaft  208  that connects to the yoke  202  at receiver  206 . A rest  210  is positioned along the shaft  208  and holds one end of an umbrella  216  (not shown in  FIG. 2 ) while the strap  402  fastens the opposite end. The saddle  414  of the case assembly  400  straddles the axle  104  between each arm of the yoke  202  and is held in place by gravity. 
     Now referring to  FIG. 3  where a variation of the device  10  is shown in a stationary mode. The variation in  FIG. 3  is principally different from that shown in  FIG. 1  in regard to the Chair assembly  301 . Chair assembly  301  is shown in include, inter alia, a frame  310 , a support  312 , a hinge  314 , a hinge  316 , a seat  318 , a back  320  and a wheel  162 . 
     The device  10  is generally in its stationary mode when the wheel assemblies  100  are disengaged from the axle  104 , the axle  104  is oriented vertical to act as a pedestal for the disk  106 . For stability of the disk  106  in stationary mode the opposing disk  106  corresponding to the opposite wheel assembly  100  can be used as a base member in contact with the ground. The fastener  114  may be stored for later use when converting the device  10  into transport mode by placing the fastener  114  in the middle of the upper disk  106 . 
     Further characterizing stationary mode, chair assemblies  301  are erected to form a chair by laying the wheel  162  onto the ground with the seat  318  side up then raising the frame  310  about hinge  316 . The support  312  then rotates away from the frame  310  about hinge  314 . The end of the support  312  opposite hinge  314  is place in ground contact to provide a stable place for a person to sit. The back  320  spans between the frame  310  to provide a comfortable back rest. 
     Yet describing the stationary mode of the device as depicted in  FIG. 3  the case assembly  400  is removed from over the axle  104 . In an embodiment of the device  10  the case assembly  400  may be an insulated cooler to keep cool beverages cool or hot food hot. Preferably the case assembly  400  is openable and sealable at seam  410 . Seam  410  may be zipper, hook and loop fastener or any other type of fastener commonly available and known in the art. 
     Still referring to  FIG. 3  the yoke assembly  200  is separated from the wheel assembly  100 , chair assembly  300  and case assembly  400  and placed flat onto the ground. The umbrella  216  may then be erected and set into receiver  204  to support the umbrella  216 . This is of particular benefit where the umbrella  216  cannot be driven into the ground, for example, in a paved lot while tailgating. 
     Now referring to  FIG. 4  where an exploded view of a variation of the device  10  is shown with a chair assembly  100  similar to that demonstrated in  FIG. 1 , an alternate yoke assembly  201  and an alternate handle  218 . 
     The chair assembly  300  in  FIG. 4  is further shown to include a hinge  305 , a hinge  307  a hinge pin  322 , pins  324 , hinge pins  326  and a port  328 . For ease of manufacture wheel  102  may be manufactured in two mirror image halves. When assembling the two halves of the wheel  102 , hinge pin  326  is inserted through hinge  306  and into hinges  307  on the wheel  102  before the halves of the wheel  102  are permanently secured to each other. Hinge pin  326  permits the radial movement of the back  302  relative to the seat  116 . Hinge  305  on the support  308  corresponds with hinge  304  on the back  302  by means of hingepin  322  secured into hinge  305  with pins  324  to permit radial articulation of the support  308  relative to the back  302 . 
     Still referring to  FIG. 4  said alternate yoke assembly  201  receives the axle  104  into forks  220 . Handle  218  is dimensioned to be used by a human hand to pull the device  10  while in transport mode. A spindle  128  and a spindle  130  join together inside the axle  104 . Said wheel assemblies  100  are removably affixed to the respective spindle  128  and spindle  130  by means of fasteners  114 . Spindle  128  and spindle  130  both freely rotate inside of axle  104  thereby permitting said wheel assemblies  100  to rotate to facilitate moving the device  10  when in transport mode. 
     Now referring to  FIG. 5  where element of the wheel assembly  100  and chair assembly  300  are shown in stationary mode forming a chair suitable for a human to sit. The elements of the chair variation shown in  FIG. 5  is materially similar to the chair assembly  300  and wheel assembly shown in  FIG. 4 . The support  308  is hingedly affixed to back  302 . Back  302  is hingedly affixed to seat  116 . Seat  116  is preferably formed integral to wheel  102 . When the chair shown in  FIG. 5  is in use in stationary mode as a chair a person can comfortably sit on seat  116  and lean back onto back  302 . Back  302  may be adjusted to varying degrees of reclination by moving support  308  nearer to or farther from the edge of the wheel  102 . A port  328  is positioned near the center of the back  302  that overlays a hub  132  to permit a fastener  114  to attach the wheel assembly  100  and chair assembly  300  to the spindle  128  (as shown in  FIG. 4 ). 
       FIGS. 6-8  show the same variation of an axle assembly  166  in more detail that includes, inter alia, a fastener  114 , a flange  118 , a cord  120 , a thread  122 , a fastener  124 , a seam  126 , a spindle  128 , a spindle  130 , a cavity  134 , seats  136  and an axle  164 .  FIG. 7  is a cross section of the view shown in  FIG. 6  at section line  7 . The axle assembly  166  shown in  FIGS. 6 and 7  is configured as it would be used in transport mode as contrasted to stationary mode. 
     Cord  120  spans through the cavity  134  inside of spindle  128  and spindle  130  and terminates on each end with a fastener  114 . The cord  120  is ideally made of an elastic cord but could also be effective if made from an inelastic material such as rope or cable. The function of the cord  120  is to prevent the loss of the fasteners  114  when transitioning the device between stationary mode and transport mode. 
     Yet referring to  FIGS. 6-8 , seat  136  is dimensioned to mate with a hub  132  (as shown in  FIG. 5 ) of a wheel assembly  100  to attach the wheel assembly  100  to the axle assembly  166  for transport mode. A wheel assembly  100  is then secured one each to the spindle  128  and spindle  130  by fastener  114  screwed into threads  122 . Spindle  128  and spindle  130  are fixed to each other at fastener  124 . Wheel assembly  100  may be attached to seat  136 . Spindle  128  and spindle  130  may then freely rotate inside of axle  164  to permit the rotation of each wheel assembly  100  when in transport mode. Flange  118  aids in positioning the axle assembly  166  onto the fork  214  of a yoke assembly  200  such as demonstrated in  FIG. 2 . 
     Optionally, the axle  164  may be manufactured in two pieces. The axle  164  would then have a seam  126 . If present, seam  126  preferably would be permanent. 
     Referring now to  FIG. 9  where a yoke assembly  200  is shown isolated from the other elements of the device  10  to reveal more detail and is shown to include, inter alia, a yoke  202 , a receiver  204 , a receiver  206 , a shaft  208 , a rest  210 , a handle  212  and forks  214 . 
     Said yoke  202  is generally semi-circular in shape and has on each end a fork  214  dimensioned to accept an axle such as axle assembly  166  as shown in  FIG. 6 . Equidistant from said forks  214  is receiver  204  dimensioned to accept an umbrella such as umbrella  216  shown in  FIG. 1  when the device  10  is in stationary mode. Adjacent to receiver  204  is receiver  206  dimensioned to accept shaft  208  which in turn terminates with a handle  212 . Near the handle  212  end of the shaft  208  is the rest  210  that holds the umbrella  216  while the device  10  is in transport mode. 
       FIGS. 10 and 11  demonstrate in more detail the disk  106  and its components that include, inter alia, a bore  108 , a rib  110  and several cup holders  112 . The disk  106  in  FIGS. 10 and 11  is similar to the disk  106  shown in  FIGS. 2 and 3 . Disk  106  is fit inside the wheel assembly  100  and axle seat  136  fits into bore  108  when in transport mode as shown in  FIG. 2 . Preferably when in transport mode the edge of the disk  106  is not in ground contact to avoid unnecessary wear on the disk  106 . When in stationary mode, as depicted in  FIG. 3 , the disk  106  is removed from the wheel  102  and erected to form a table with the corresponding disk  106  of the pair acting as a base when in ground contact. One or more cup holders  112  are optionally positioned around the periphery of the disk  106  that are dimensioned to facilitate the insertion and support of a common beverage container. Optionally, a rib  110  is present on one side of the wheel  106  to stiffen and strengthen the disk  106 . 
       FIGS. 12 and 13  show in more detail the case assembly  400  separated from the other various elements of the invention. Said case assembly  400  is shown to include, inter alia, a strap  402 , a panel  404 , a frame  406 , a case  408 , a seam  410 , a seam  412 , a saddle  414 , a panel  416 , a panel  417 , a handle  418  and a hinge  420 . The case assembly  400  shown in  FIGS. 12 and 13  is similar to the case assembly  400  shown in  FIG. 2 . 
     The case assembly  400  is generally forms two hollow interior volumes, a first volume bounded by case  408  and a second volume bounded by panel  416  and panel  417 . Said first volume accessible by unsealing seam  410  and raising panel  417  by pivoting about hinge  420 . Said seam  410  may include a closure means such as a zipper, straps, hook and loop fasteners, snaps, buttons or other commonly available means to reversibly seal the seam  410 . Said second volume is generally bounded by panel  417  and panel  416 . The interior of said second volume is opened and closed at seam  412 . Said seam  412  may include a closure means such as a zipper, straps, hook and loop fasteners, snaps, buttons or other commonly available means to reversibly seal the seam  412 . In one contemplated use of the case assembly  400  said first volume may be insulated and used as a cooler for food and beverages while said second volume may be used to store items preferably kept dry such as a phone, keys, camera and clothes. It would be obvious to one knowledgeable in the art that anything that would fit inside either of said first or second volumes may be placed inside for storage or transport. 
     Said saddle  414  bisects the case and provides a means to support the case assembly  400  over the axle  104  (shown in  FIG. 2 ) while the device is in transport mode. When in transport mode the case assembly  400  need not be secured with any fastening device to the axle  104  because gravity holds the case assembly  400  securely in place over the axle. 
     Yet referring to  FIGS. 12 and 13  it is shown that a frame  406  may optionally be present to form a cage around the exterior of the case  408  to lend strength and rigidity to the case  408 . The frame  406  is increasingly preferred when the case  408  is less rigid, for example when the case  408  is constructed of an insulated soft-sided fabric system. 
     In the embodiment of the case assembly  400  demonstrated in  FIGS. 12 and 13  a strap  402  is present to aid in securing an umbrella to the panel  416  while in transport mode. Handles  418  are present on opposite sides of the case  408  to aid in moving the case assembly  400  when unmounted from the yoke assembly  200  (shown in  FIG. 2 ). 
       FIG. 14  shows a variation of the invention particularly emphasizing a variation of a chair assembly  303  and shown in transport mode. This variation of the chair assembly  303  is shown to include, inter alia, a hinge  138 , a seat  140 , a back  142 , a frame  144 , a frame  146 , a bar  148 , notches  150 , a clip  152 , a clip  154 , a wheel  156 , a hinge  158 , a hinge  159  and a bar  160 . The case assembly  400  and yoke assembly  200  are similar to those shown in  FIG. 2 . 
       FIGS. 15 through 19  show the same chair assembly  303  in stationary mode as depicted in  FIG. 14 . When transforming from transport mode to stationary mode the wheel  156  and chair assembly  303  are removed from the yoke assembly  200  and case assembly  400  (shown in  FIG. 14 ). The wheel  156  is placed onto the ground or other suitable surface with the seat  140  facing up. Clip  154  is snapped out of clip  152  and the frame  144  is raised about hinge  138 . Frame  146  is rotated away from frame  144  about hinge  159  and the edge of the frame  146  opposite that of hinge  159  is brought into ground contact to support the frame  144 . 
     To secure the angle between the frame  144  and frame  146  the bar  148  is extended straight by means of hinge  158 . As shown in more detail in  FIGS. 16 through 19  the angle of the frame  144  relative to the seat  140  can be securely adjusted by fitting any of the several notches  150  over the bar  160  (shown in  FIG. 15 ). A user of the chair assembly  303  may desire to adjust the angle of the frame  144  relative to the seat  140  to increase comfort by reclining to a lesser or greater degree. 
     Back  142  is disposed between the edges of frame  144  to provide a soft and resilient surface upon which a user of the chair assembly  303  may rest their back. Back  142  may be constructed of a fabric, plastic, natural fiber or other material suitable for a user to rest against while sitting in the chair assembly  303  while in stationary mode. 
       FIG. 20  shows another variation of the invention particularly demonstrating a variation of a chair assembly  301  that is shown to include, inter alia, a wheel  162 , a frame  310 , a support  312 , a hinge  314 , a seat  318 , a back  320  and a clip  330 . The yoke assembly  200  and case assembly  400  remain similar to those shown in  FIG. 2 .  FIG. 20  shows the chair assembly  301  in transport mode, ready to travel to the beach. 
     A user of the chair assembly  301  in stationary mode places the wheel  162  in ground contact with the seat  318  side up. The user is able to sit on seat  318  cleanly off the ground and recline her body onto back  320 . Back  320  is preferably a durable material such as fabric, plastic, natural fiber or other material suitable for a user to rest against while sitting in the chair assembly  301 . The back  320  is supported on its edges by frame  310 . 
       FIG. 21  represents the chair assembly  301  removed from the other components of the invention shown in  FIG. 20  and erected into the stationary mode of the chair assembly  301 .  FIGS. 22 through 24  illustrate the sequence of steps of transforming the chair assembly  301  from transport mode as best shown in  FIG. 22  into stationary mode as depicted in  FIGS. 21 and 24 . 
     Generally to transform the chair assembly  301  into it stationary mode the wheel  162  is placed on a surface (i.e. ground, sand, pavement, bleacher, etc. . . . ) and frame  310  is raised from against the wheel  162  about hinge  316  to form a seat back as shown in  FIG. 23 . The support  312  is then rotated away from frame  310  about hinge  314 . The end of frame  312  opposite that of hinge  314  is placed in ground contact to act as a brace to maintain the angle between the frame  310  and the seat  318 . 
     Optionally, the length of support  312  may be adjustable to better support the frame  310  at the desired angle relative to the seat. The adjustability can be achieved by forming the support  312  from concentric tubes. An outer tube having a series of holes may be provided to accept a snap clip inside of an inner tube. The snap clip may then be selectively engaged into any of the holes on said outer tube to achieve the appropriate length of the frame. Said tubes that comprise the frame  312  may effectively have round, square, oval or other suitable cross section profile. Said frame  312  and frame  310  is optimally constructed of aluminum, plastic or any other light weight and rigid material known in the art. 
       FIGS. 25 and 26  show a variation of the present invention in transport mode and particularly emphasizes alternate chair assembly  309  and alternate case assembly  401  while the yoke assembly  200  remains similar to the yoke assembly  200  shown in  FIG. 2 . Said alternate chair assembly  309  is shown to include, inter alia, a wheel  222 , a back  224 , a clip  226 , a frame  228 , a seat  230 , a disk  232 , a bore  234 , cup holders  235  and a fastener  236 . Said alternate case assembly  401  is shown to include, inter alia, a bore  422 . Other elements of  FIGS. 25 and 26  include a fork  214 , an umbrella  216 , threads  122  and an axle  164 . 
     Said case assembly  401  utilizes the axle  164  penetrated through bore  422  to support the case assembly  401 . Said axle  164  is set into said fork  214  of the yoke assembly  200  so that the case assembly  401  is suspended above the ground when transporting the invention on its wheels  222 . In other regards the case assembly  401  is similar to the case assembly  400  shown in  FIGS. 12 and 13 . 
     Yet referring to  FIG. 26  the disk  232  has a multiplicity of cop holders  235  arranged in a predetermined pattern around the periphery of the table and are dimensioned to accept commonly sized beverage containers. The disk  232  and axle  164  may be erected into a table when converted into stationary mode similar to the disk  106  and axle  104  as shown in  FIG. 3  and described above. 
     When assembled into transport mode the axle  164  passes through the bore  422  in the case assembly  401 . The axle  164  then rests one end on each of the forks of the yoke assembly  200 . One each of said disks  232  is nested against the edge of each wheel  222  opposite the seat  230 . For each of said wheel assemblies  309  of the pair, said bore  234  and a bore  336  (shown best in  FIG. 27 ) on the center of the wheel  222  are fitted onto the end of each respective end of the axle  164  and removably secured to the axle  164  by said fastener  236  engaging said threads  122 . One each of said chair assemblies  309  is removably attached to each of said wheels  222  on the seat  230  side of said wheels  222  by means of a clip  226 . Preferably a multiplicity of clips  226  are used to secure the chair assembly  309  to the wheel  222  while use in transport mode. 
     Referring to  FIGS. 27 through 31  where a more detailed view of the chair assembly  309  and it&#39;s several adjustments are demonstrated and shown to include, inter alia, a wheel  222 , a back  224 , a frame  228 , a seat  230 , peg  332 , notch  334 , bore  336 , a cap  424  and a channel  426 . 
       FIG. 27  illustrates the chair assembly  309  in stationary mode, ready to be used as a chair. The wheel  222  is placed onto a surface such as the ground, a bleacher, sand or other appropriate surface with the seat  230  side up. The frame  228  is erected from its position against the seat  230  as it is used in transport mode (see  FIG. 25 ). Pegs  332  formed integral to the frame are set into any of the predetermined notches  334  to secure the angle of the frame  228  relative to the seat  230 . A back  224  spans between edges of the frame  228  to provide a stable support for a person using the chair assembly  309  a comfortable surface to recline upon. 
       FIGS. 28 through 31  demonstrate in more detail the varying degrees of reclination that frame  228  may be adjusted to relative to the seat  230 .  FIG. 28  includes the cross section reference line  29  that corresponds to the cross section view in  FIG. 29 .  FIGS. 30 and 31  are cross sectioned at the same plane on the wheel  222  as  FIG. 29 . 
     Generally, the frame  228  is held in place gravity. The pegs  332  on each side of the frame  228  engage into one of the several notches  334  on each side of the seat  230 . Caps  424  on each end of the frame  228  seat on each side into the channel  426 . When the pegs  332  are set into the pair of notches  334  nearer the center of the seat  230  the frame  228  and therefore back  224  are oriented more towards the vertical relative to the plane of the seat  230 . As pegs  332  are engaged into notches  334  further from the center of the seat  230  the back  224  reclines further. It can be appreciated that a user of the chair may find it more comfortable to sit in the chair assembly  309  with the back  224  at varying degrees of recline. 
     It would be understood that any of the wheels  102  (or other variations of wheels) may be rotatably attached to an axle  104  (or other variations of an axle) by means of ball bearings, roller bearings or other type of means commonly available in the art to permit the wheels  102  to readily rotate and remain durable. Any of the wheels  102  (or other variations of wheels) may have a durable cover around the circumference of the wheel  102  such as rubber or other gripping and durable material to grip onto a surface while the device is used in transport mode.
