Title: Solar Oven Positioning

Description:
BACKGROUND 
     A solar oven uses the energy of direct sunlight to heat food or drink. Solar cooking is a form of outdoor cooking and is often used where it is desired to minimize fuel consumption. Use of solar ovens helps reduce fuel costs and air pollution. It can also help to slow down deforestation and desertification where the alternative is to use gathered firewood for cooking. 
     A solar oven produces heat by concentrating sunlight and converting the light to infrared heat. Typically, a reflective mirror of polished glass, metal metalized film concentrates light that then is used to produce heat from the sun. The heat is contained in a small cooking area. A solar oven makes efficient heat by the conversion of light to heat. This is done, for example, by using a black or other low reflectivity surface on cooking containers to create heat that is added and trapped in the cooking area. 
     The solar oven is positioned towards the sun in order to maximize heat generation. As the sun travels across the sky, the position of the solar oven can be adjusted to optimize position with respect to the sun and to avoid shadows. When the solar oven is to be used for several hours untended, the solar oven can be turned to face the zenith of the sun&#39;s path so as to optimize captured radiation during the day.

     DETAILED DESCRIPTION 
     A solar oven system is installed on an outside wall of a building structure outside the cooking area and accessed through a window or other opening accessible from within the cooking area with the apparatus reaching out away from the building structure into the outside environment when operated. The solar oven system integrates all of the needed solutions of the various operation process steps and numerous problems related to the requirements of the entire solar cooking process into one complete seamless cohesive operation. 
       FIG. 1  and  FIG. 2 , of the solar oven system  30  shows a basic version of a solar oven system embodiment installed onto a building structure. A solar oven system  30  includes an extended positioning system  32  and a radiation collection device. For example, the radiation collection system is represented in  FIGS. 1 and 2  by a box solar oven assembly  180 . Box solar oven assembly  180  is used for converting solar energy into heat for cooking food or other solar processes. Positioning system  32  is used to deploy, and align box solar oven assembly  180 . 
     The extended positioning system  32  is installed, mounted, or connected onto the wall by features in  FIGS. 3, 4, 5 , &amp;  10  with a saddle top retaining stud  170 , saddle bottom retaining bracket  172 , and a ground foundation block  178 . A wall mount system  164  includes a pivot post saddle weldment  166 , of which includes an M-shape saddle  168  ( FIG. 10 ) to nest a pivot post  174 , saddle top retaining stud  170  for top attachment to the building structure, and a saddle bottom retaining bracket  172  for the bottom attachment to the building structure. The wall mount system  164  also includes a pivot post  174  for receiving a pivot weldment  40 , two pivot post straps  176  to secure and adjust the pivot post into a pivot post saddle weldment  166 , and a ground foundation block  178  to support the vertical component force loads of an embodiment itself and its process operation loads. 
     The saddle top retaining stud  170  is inserted into a hole located in the underside of the exterior lower horizontal window frame material or is already provided by the existing vertical grooves in the building siding material, (such as “T111 and other siding materials with vertical groove features) when the lower horizontal window frame material is mounted over the grooves which then provides a hole feature which can be used as the retaining hole to secure the upper portion of the wall mount system. The saddle bottom retaining bracket  172  slides behind and onto the lower edge of the building siding material between the vertical flange of the saddle bottom retaining bracket  172  and the M-shape saddle  168  mounting surface therefore retaining the lower portion of the wall mount onto the wall material. The M-shape saddle  168  is configured to provide the center portion of the design to protrude out beyond the outer edges or general surface plane of the wall mounting surface of the M-shape saddle  168  therefore providing insertion of the M-shape saddle  168  center material protruding into the siding vertical groove for preventing twisting after mounting and adding strength and retention of the system in any position after installation. The ground foundation block  178  supports the entire vertical component load force vector after adjusting and setting of the installation to the wall. This design removes (or prevents) the vertical load force component vector from the installed pivot post saddle weldment  166  and keeps the wall mount system  164  from disengaging vertically downward. It does this by first redirecting all the vertical load force directly down onto the ground providing for a load path which provides no unnecessary vertical force on wall mount weldment  166 , therefore, not requiring additional fastening methods in order to retain the wall mount weldment  166  vertically onto the building structure. The pivot post straps  176 , after installed and setup, only provide retaining of the pivot post  174  into the pivot post saddle weldment  166  in the horizontal component force vector loading directions. 
     The wall mount system  164  is installed on to the wall by inserting and sliding the pivot post saddle weldment  166  into the groove of the siding material and simultaneously sliding up and in both the saddle top retaining stud  170  along with the saddle bottom retaining bracket  172  simultaneously into their proper securing locations on the wall as previously described above. The pivot post  174  is then inserted into the “M” shape saddle  168  nesting feature as shown in  FIG. 4  with the two pivot post straps  176  while loading a downward vertical force of the pivot post  174  onto the ground foundation block  178  before tightening the two pivot post straps  176  in place. As stated above, this design and setup prevents the vertical load force from siding out the upper and lower retaining features of the previously described pivot post saddle weldment  166 . No fasteners are required to make the secure installation to the building wall because of this vertical load path design directing to the ground foundation block  178  first, which again, prevents sliding out of the weldment  166  retaining features. 
     Extended positioning system  32  in  FIGS. 2, 4, and 5  includes a structural extension assembly  34  that provides linear extension and manipulation of the box solar oven assembly  180  out away from the building structure. The structural extension  34  includes two U-shape channel rail members  36 R and  36 L connected together by cross members  38  assembled by screws, welds or other standard structural attachment methods. Referring to  FIG. 4 , the cross members  38  have a hole in the center with set screws at the plate edge in order to receive and secure for attachment a horizontal beam supporting member  44  of a pivot weldment  40 . 
     The pivot weldment  40  includes a vertical pivoting member  42  including a feature of a welded stud  46  for brace bar  50  attachment for structural support and a horizontal beam supporting member  44  which provides pivoting attachment of the structural extension  34  to the wall mount system  164 . Set screws provided in the structural extension  34  cross members  38  are used to secure to the horizontal beam supporting member  44 . A lower portion of the vertical pivoting member  42  of the pivot weldment  40  is then slip fit into the top of the pivot post  174  in  FIGS. 2 and 4  to allow pivoting (angular rotation) of the structural extension  34  using an extendable lever handle  156  by the operator. A beam suspension support truss assembly  48 , made up of the brace bar  50  and a brace bar attachment bracket  52  attached with screws or other methods to the structural extension  34  provides structural strength required to significantly extend and support operational load weights during operations. 
     Referring to  FIGS. 4, 6, and 9 , a moveable carriage  58  slides or rolls along the structural extension assembly  34  in a linear movement on vertical load shafts, bearing rollers, and collars assembly  70  to carry (or roll) the box solar oven assembly  180  into optimum locations for operating an embodiment. The moveable carriage  58  is attached to the structural extension assembly  34  by four lateral shafts and rollers assemblies  64  in  FIGS. 6 and 9 , which keeps the moveable carriage aligned and trapped to prevent any side derailment. Moveable carriage  58  also has two roller brackets  62  with material extending under the U-shaped channel members  36 R and  36 L flanges in  FIG. 6  for interference between channel members flanges and roller brackets  62  when a vertical ascending movement is applied. This prevents upward disengagement from the structural extension assembly  34 . These features keep the moveable carriage  58  from being lifted or removed from the structural extension assembly  34  while allowing only a longitudinal degree of freedom movement (linear) of the moveable carriage  58  along the length of the structural extension assembly  34 . Further, the moveable carriage  58  is prevented from rolling or sliding off the end of the structural extension assembly  34  by a cable loop pulley mount plate bracket  128 , therefore securely trapping the moveable carriage  58  (during assembly) onto the structural extension  34  while in operation. 
     The moveable carriage  58  in  FIGS. 4, 6, 7, 8, and 9  includes a base plate assembly  78  made up of a structural base plate  80  with nesting pins  82  threaded (with machine nuts) or other methods of securing, positioning, and attaching a pedestal base  248  ( FIG. 12 ) of the box solar oven assembly  180  onto the extended positioning system  32  in  FIG. 2 . Two rollers and carriage retaining assemblies  60  attach to the underside of base plate  80  with screws or a like standard attachment to create the carriage movement mechanism. It provides vertical load shafts  72 , and vertical load bearing rollers  74 , with rubber press fit retaining vertical load shaft collars  76 , for moving or driving the carriage along the structural extension assembly  34 . Carriage retaining assembly  60  provides for lateral control using lateral shafts and rollers assembly  64  with lateral roller shaft  66  and lateral rollers  68  guiding the carriage with the edges ( FIG. 6 ) of the U-Shaped channel members  36 R and  36 L to prevent derailment. Vertical load shafts, bearing rollers, and collars assemblies  70  carry the box solar oven assembly  180  weight along the structural extension assembly  34 . The roller bracket  62  is sized and configured to provide interference with the U-shaped channel rail members  36 R and  36 L as stated earlier to prevent detachment and removal from the structural extension assembly  34 . 
     Referring to  FIGS. 2, 3, 11, 12, and 13  the box solar oven assembly  180  includes an insulated assembled foam box  182  ( FIG. 13 ) which includes a foam box top  184 , foam box sides  186 R and  186 L with clearance holes for the stationary horizontal pivot bearing bolts  234  supported by a yoke member  228 , and a foam box bottom  188  assembled at all the corner joints with long wood screws or other suitable connecting methods. The foam material used is rigid polyisocyanurate Aluminum foil faced foam board used in building construction. Energy Shield® by Atlas Roofing Corporation®, or Thermasheath and TSX 100 and 200, by Rmax Inc., or other standard building foam with two-sided foil can be used for the insulated foam box  182  structure. It can be any standard thickness 1.5 inches or greater. 
     A formed sheet metal hoop strap  192  assembles around (slides onto) the foam box main body area and is then secured by tightening the two screws at a hoop clamp opening ( FIG. 2  under bottom collector panel). The clamping system includes two parallel flanges bent 90 degrees outward at each end of the hoop strap material with two clearance holes with screws in each for tightening the clamp together. The clamping system is tightened until it cinches (clamps) tight therefore providing a hoop stress compression force strength around the entire main body of the insulated foam box structure. This hoop strap  192  provides a significant strength improvement to the foam box structure  182  without adding excessive weight or requiring other less desirable methods for structural integrity and strength. There are two holes located in the hoop strap  192  for flange bearings  194  ( FIG. 13 ) to be inserted which are for rotating the box solar oven  180  ( FIG. 12 ) on the stationary horizontal pivot bearing bolts  234  supported by the yoke member  228 . The hoop strap  192  depth is larger (wider) than the top width of the foam box top  184  therefore creating a recessed well at the front glazier opening having a depth of the thickness of the stacked two glaziers  196  of clear plate glass or equivalent with the glazier spacer frame  198  in between. This recessed well provides for insertion, at the front of the insulated foam box  182  edge face, for secure placement in two degrees of freedom of the inner and outer glaziers  196  and glazier spacer frame  198  assemblage. A tight seal for heat retention of the inner glazier  196  to the foam box edge along with the glazier spacer frame  198  between both the inner and outer glaziers  196  is made with a solar collector panel mount retainer and insulating enclosure frame assembly  202  ( FIG. 13 ) by using a solar collector panel mount retainer and insulating enclosure frame  204 , which retains and traps the glazier system securely and tightly in place down into the recess well and onto the foam surface when slid on over the hoop strap&#39;s  192  outer surface down to the outer glazier surface. The insulating enclosure frame  204  is then secured with sheet metal screws (not shown) into the hoop strap  192  on both side ends. A solar collector panels assembly  208  made up of solar collector panels  210  segments is assembled by inserting the lower flanges of the solar collector panels  210  under the solar collector panel mount retainer and insulating enclosure frame  204  opening flanges before assembling the insulating enclosure frame assembly  202  onto the hoop strap  192 . The solar collector panel mount retainer and insulating enclosure frame  204  after attachment, is what holds the glazier and solar collector panel systems securely in place by using the hoop strap  192  main structure. 
     A formed sheet metal cover protector assembly  212  provides exterior protection of the foam material not covered by the hoop strap  192 . A cover protector  214  is inserted onto the insulated foam box  182  with its sides passing over the hoop strap  192  material and when in position the cover protector  214  is then secured with sheet metal screws (not shown) into each side to the hoop strap  192  structure. A door assembly  218  slides into the rear opening of the insulated foam box snugly with a degree of interference for heat retention using a door handle  222 . An added appropriate surface of plastic or other suitable material (not shown) can be inserted into the assembled foam box  182  on the foam/foil surfaces if desired to protect and insulate to facilitate and accommodate operation wear and cleaning. 
     Referring to  FIGS. 3, 11, and 13 , A light alignment indicator assembly  256  is used to indicate azimuth and solar altitude alignment of the box solar oven assembly  180  with respect to the related perpendicularity of the glazier surface to the sun&#39;s incoming rays. It includes a tube scope box mounting bracket  258  which positions and mounts a light indicator tube  260  attached with clamping collars (not shown) or other method around the tube at the mounting bracket surfaces with the light indicator tube  260  positioned perpendicular to the glazier surface in two directions. A translucent light target assembly  262  provides for a translucent target  264  to be parallel and away from the tube  260  end plane  FIG. 13 ). The translucent light target assembly  262  includes a clamp type target mounting bracket  266  which connects or clamps onto the light indicator tube  260  extending past the light indicator tube  260  end to position the translucent target  264  parallel and away from the tube  260  end plane needed for projecting the sun rays (light beam) out of the tube onto the translucent target  264  for visual reading on either surface of the target material (front or back). The light alignment indicator assembly  256  is attached with the tube scope mounting bracket  258  into the box solar oven assembly  180  solar collector panel mount retainer and insulating enclosure frame assembly  202  with screws. 
     Referring to  FIG. 12 , an azimuth bearing and pedestal base assembly  242  for positioning and rotating the box solar oven assembly  180  includes a pedestal base  248  providing a stable ballast stand frame structure screwed or connected by other standard methods to an azimuth 12 inch bearing bottom mount plate  246 , then is connected to an azimuth 12 inch bearing  250 , which is then mounted to an azimuth 12 inch bearing top mount plate  244  which provides a mounting surface to connect to the yoke member  228 . A center of gravity biaser spring  252 , screwed and mounted to the plate  244  surface is provided to keep a solar altitude cable winch cable  100  tight at all times and therefore fully operational at any position in the 90-degree rotation range. The center of gravity biaser spring  252  is designed to keep a constant force or biased push on the box solar oven assembly  180  in one direction throughout the entire adjustment range, thereby eliminating a characteristic reverse rotating reaction caused by a change in the center of gravity moment due to the unique box solar oven  180  design shape. 
     A solar altitude locking bar  254  in  FIG. 12  is connected with a pivoting screw at one end onto the box solar oven assembly  180  and to the yoke member  228  with its adjusting slot. This provides for solar altitude locking bar  254  being able to slide in a long slot at the yoke member  228  when the box solar oven assembly  180  is rotated. By tightening a locking finger screw (not shown) in the long bar slot at the yoke member  228 , a clamping action of the bar to the yoke member occurs, therefore locking the box solar oven assembly  180  into a set position. This is used for manually locking the rotating altitude position when needed during manual operations, handling, or maintenance. 
       FIG. 11  shows a food rack and supports assembly  230  inside the box solar oven assembly  180 . The food rack and supports assembly  230  includes two horizontal pivot bearing bolts  234  supported by the yoke member  228  ( FIG. 12 ) as discussed earlier. These bolts are mounted stationary to the yoke member  228  with machine nuts and protrude through the flange bearing assembly and out into the box solar oven assembly  180  cooking or heating interior compartment for assembling the food rack and supports assembly  230 . Two food rack side plates  236  are rigidly connected with machine nuts to the two horizontal pivot bearing bolts  234 . Two food rack cross rods  238  are rigidly connected with machine nuts at each corner of the lower portion of two food rack side plates  236 . A food rack horizontal plate  240  then sits on top the two food rack cross rods  238  maintaining its position vertically by its own weight. The food rack horizontal plate  240  has the two longitudinal side edges bent 90 degrees down or can have four leg type features extending or protruding from the bottom surface of the plate for trapping the plate itself onto (straddling) the two food rack cross rods  238  when in operation. Horizontal plate  240  is trapped (secured) between the two food rack side plates  236  and each of the outer diameter sides of the two food rack cross rods  238 . 
     Referring to  FIGS. 2, 3, 4 and 5 , the extended positioning system  32  includes a remote-control mechanism and devices  120  ( FIG. 2 ). Remote control mechanism and devices  120  is designed to operate for position, adjusting, and solar alignment in any infinite continuous location or position along the extended positioning system  32  with the operator located within the building structure. 
     A linear positioning mechanism used to position the box solar oven assembly  180  along the extended positioning system  32  includes and referring to  FIGS. 3, 4 and 5 , is a linear hand wheel  122  attached with a set screw or other standard method to a cable drive spool  124  which is then slip fit over the vertical pivoting member  42  for rotation of the cable drive spool  124  when in use. A cable drive spool collar  56  attached with a retaining screw to the vertical pivoting member  42  provides a thrust bearing surface for the turning spool  124  to run and slide on thereby reducing friction when rotating while also simultaneously setting the position of cable drive spool  124  on the assembly. A carriage drive cable  130  wraps a series of turns around the cable drive spool  124  in a tight fashion therefore providing frictional attachment to pull all the weight of the box solar oven assembly  180  on moveable carriage  58  in either linear direction without slippage. One end of the carriage drive cable  130  is attached or connected with clamps or a hook method to the vertical load shaft  72  ( FIG. 9 ) closest to the cable drive spool  124  of the moveable carriage  58 . The second end of the carriage drive cable  130  passes under the moveable carriage  58  and out the other side and down the structural extension assembly  34  to the end where cable loop pulley  126  is mounted onto the structural extension assembly  34  end with cable loop pulley mount plate bracket  128  by conventional methods and is looped around the cable loop pulley  126  to return to the second vertical load shaft  72  for again attachment to the moveable carriage  58 . This system provides pulling tension of the cable for either direction of movement of moveable carriage  58  when the cable drive spool  124  is rotated in either direction. 
     An extendable lever handle  156  mechanism is used by the operator for polar angular rotation positioning of the extended positioning system  32 . Referring to  FIGS. 2, 4, and 5 , this control mechanism includes an extendable lever handle  156  with a set screw attached access knob positioning collar  158  at the user end. The other end of extendable lever handle  156  is assembled with a pivot pin into a sliding drive block pivot yoke  160  providing for the extendable lever handle  156  to be pivoted (or rotated) 90 degrees from horizontal to vertical or vice versa when in use. The sliding drive block pivot yoke  160  fits and is assembled into a wrench drive plug  162  and after insertion a press fit retaining pin (not shown) is put into the sliding drive block pivot yoke  160  block body which captures the yoke  160  into the wrench drive plug  162 . Then wrench drive plug  162  is then mounted and attached using two blind, screw tapped holes with set screws which are inserted through clearance holes in the diameter of the vertical pivoting member  42  of the pivot weldment  40  at the top and tightened into the wrench drive plug  162  thereby securing them together. 
     Referring to  FIGS. 2, 4, 6 and 7 , an azimuth positioning remote control mechanism includes an azimuth hand wheel and hand wheel drive shaft assembly  132 , an azimuth worm gear drive mechanism  104 , an azimuth bearing drive roller assembly  102 , and an azimuth 12 inch bearing  250  ( FIG. 12 ). 
     The azimuth hand wheel and hand wheel drive shaft assembly  132  includes the azimuth hand wheel  134  attached with a retaining screw to an azimuth hand wheel drive shaft  136  which extends down through a running slip fit clearance hole in the top of an azimuth miter gear drive shaft bracket  138  interconnecting with a first azimuth miter gear  140  which engages a second miter gear  140  therefore together changing the rotating power direction 90 degrees from vertical to horizontal. The second azimuth miter gear  140  is connected to a special azimuth D-profile drive shaft  142  that then runs the entire length of the structural extension assembly  34 . The azimuth D-profile drive shaft  142  is mounted in running slip fit bearing clearance holes at each end at the bottom of the azimuth miter gear drive shaft bracket  138  and at the cable loop pulley mount plate bracket  128  to allow for power transfer rotation using the bearing holes. The miter gears  140  are fixed to the shafts with set screws or other mechanical common methods. 
     The azimuth worm gear drive mechanism  104  has a worm  106  that is mounted with its bore onto the D-profile drive shaft  142  with a running slip fit bearing clearance so it slides along the D-profile drive shaft  142  when the moveable carriage  58  is driven linearly with the cable drive spool  124 . The bore of the worm is configured to either have a flat spot or keyed feature in the diameter, or a mechanical clip method (not shown) on its hub to provide a key type feature that prevents the worm from rotating around the D-profile shape of shaft  142  when rotational force is applied, yet still allowing free sliding longitudinally along the D-profile drive shaft  142 . The design transfers the rotating power from the D-profile drive shaft  142  to the worm at any location along the extended positioning system  32 . The rotating azimuth worm  106  engages an azimuth worm gear  108  which is connected to a drive roller shaft  114  and is passed through a running slip fit bearing clearance hole in an azimuth worm gear housing  110  ( FIG. 8 ) that is machine screwed or attached by other common methods to the base plate  80  of the moveable carriage  58 . A drive roller collar  118  secures and positions the azimuth worm gear  108  and drive roller shaft  114  together to the azimuth worm  106 . A Drive roller  116  is attached in a secure standard method to the top of the drive roller shaft  114  to transfer the rotating power to the side edge of azimuth 12 inch bearing  250  ( FIG. 12 ) and rotate the box solar oven assembly  180  for azimuth positioning and adjustments. At the interface between drive roller  116  and the side edge of azimuth 12 inch bearing  250 , pressure is applied into the edge of the side edge of azimuth 12 inch bearing  250  with enough force to provide friction to drive the system. The force of the drive roller  116  may be achieved by various design methods including using a rubber roller preloaded at the side edge of azimuth 12 inch bearing  250  by setup adjustment of the azimuth worm gear housing  110  to the base plate  80  of the moveable carriage  58 . Another design method (not shown) is to wedge shape the drive roller  116  in a downward fashion to jam (or wedge) the drive roller  116  into and against the side edge of the azimuth 12 inch bearing  250  using the downward force of gravity and/or another collar (not shown) to preset the downward wedge force in preloading setup. The rotational power can now be transferred from the operator&#39;s hand (azimuth hand wheel  134 ) to the azimuth 12 inch bearing  250  on the moveable carriage  58 , at any location along the entire extended positioning system  32  distance. 
     Referring to  FIGS. 2, 4, 5, 6, 7, 8, and 9 , the solar altitude positioning control mechanism includes a solar altitude hand wheel and hand wheel drive shaft assembly  144  (shown in  FIG. 2 ), a solar altitude worm gear drive mechanism  86 , a cable winch drum and shaft assembly  94  and a cable winch cable  100  which is attached to a solar altitude cable attach bracket  216  ( FIG. 12 ). 
     The solar altitude hand wheel and hand wheel drive shaft assembly  144  includes a solar altitude hand wheel  146  attached with a retaining screw to a solar altitude hand wheel drive shaft  148  which extends down through a running slip fit clearance hole in the top of a solar altitude miter gear drive shaft bracket  150  interconnecting with a first solar altitude miter gear  152  which engages a second miter gear  152  therefore together changing the rotating power direction 90 degrees from vertical to horizontal. The second solar altitude miter gear  152  is connected to a special solar altitude D-profile drive shaft  154  that runs the entire length of the structural extension assembly  34 . The solar altitude D-profile drive shaft  154  is mounted in running slip fit bearing clearance holes at each end at the bottom of the solar altitude miter gear drive shaft bracket  150  and at the cable loop pulley mount plate bracket  128  to allow for power transfer rotation using the bearing holes. The miter gears  152  are fixed to the shafts with set screws or other mechanical common methods. 
     The solar altitude worm gear drive mechanism  86  has a worm  88  that is mounted with its bore onto the D-profile drive shaft  154  with a running slip fit bearing clearance so it slides along the D-profile drive shaft  154  when the moveable carriage  58  is driven linearly with the cable drive spool  124 . The bore of the worm is configured to either have a flat spot or keyed feature in the diameter, or a mechanical clip method (not shown) on its hub to provide a key type feature that prevents the worm from rotating around the D-profile shape of shaft  154  when rotational force is applied, yet still allowing free sliding longitudinally along the D-profile drive shaft  154 . The design transfers the rotating power from the D-profile drive shaft  154  to the worm at any location along the extended positioning system  32 . The rotating solar altitude worm  88  engages a solar altitude worm gear  90  which is connected to a cable winch shaft  96  which is passed through a running slip fit bearing clearance hole in a solar altitude worm gear housing  92  that is machine screwed or attached by other common methods to the base plate  80  of the moveable carriage  58 . The cable winch shaft  96  is also passed through a running slip fit bearing clearance hole in the azimuth worm gear housing  110  that is machine screwed or attached by other common methods to the base plate  80  of the moveable carriage  58  ( FIG. 8 ). A cable winch shaft  96  retaining collar, where the cable winch shaft  96  passes through the solar altitude worm gear housing  92  (not shown) secures and positions the solar altitude worm gear  90  and cable winch shaft  96  together to the solar altitude worm  88 . 
     Referring to  FIGS. 9 and 12 , a cable winch drum  98  is attached in a secure standard method to the cable winch shaft  96  to transfer the rotating power to a linear pull of the solar altitude cable winch cable  100 , which then pulls to rotate the box solar oven assembly  180  for solar altitude positioning and adjustments. The solar altitude cable winch cable  100  is attached to the cable winch drum  98  with a set screw clamping design consisting of a tapped machine thread hole at the end of the drum intersecting a cable retention hole therefore being able to trap the cable securely to the drum. 
     The solar altitude cable winch cable  100  is wrapped around the cable winch drum  98  as many times as needed to provide enough linear cable length to rotate the box solar oven assembly  180  in any position within 90 degrees from horizontal to vertical for all possible operation applications. Solar altitude cable winch cable  100  then passes through the moveable carriage base plate  80 , up through the azimuth bearing and pedestal base assembly  242 , and attaches to the underside of the box solar oven assembly  180  at the solar altitude cable attach bracket  216  which is attached with screws to the cover protector  214  again with a set screw clamping design consisting of a tapped machine thread hole intersecting a cable retention hole for clamping the cable end securely into the solar altitude cable attach bracket  216 . The rotational power can now be transferred from the operator&#39;s hand (solar altitude hand wheel  146 ) to the box solar oven assembly  180  at the solar altitude cable attach bracket  216  for rotation even when the moveable carriage  58  is at any location along the entire extended positioning system  32  distance. Furthermore, in this design, when the box solar oven assembly  180  is rotated with the azimuth control, the solar altitude cable winch cable  100  can flex and twist from the drum to the cable attach bracket  216  for the required flexibility needed to position the azimuth simultaneously with solar altitude ranging from less than 90 degrees to greater than 270 degrees of azimuth rotation positions. 
     Referring to  FIG. 1 , a protective storage shelter cover  268  is mounted to the side of the opening on the building above the height of the box solar oven assembly  180  with standard fastening methods. The box solar oven assembly  180  is manipulated with the extended positioning system  32  under the protective storage shelter cover  268  for storage until later use. 
     Referring to  FIGS. 14, 15, and 16 , these diagrams illustrate and indicate the relative increased reach capabilities provided by solar oven system  30  to retrieve solar exposure around a general building structure.  FIG. 14  shows the solar oven system  30  extending out in order to meet both summer and winter sun paths which eliminates shadowing from the building overhang and corners.  FIGS. 15 and 16 , show the potential angular projections of solar radiation exposure in perspective and top views. These views indicate how, in varied application directions, the system  30  can reach back (around a building corner) approximately 11 degrees at a 6 ft. extension of the extended positioning system  32  for increased solar exposure time and thus accommodate more varied building directions and geographic locations for universal utility.  FIG. 16  shows how an east or west solar oven system  30  application can get increased solar exposure time due to reach back around a building corner. 
     The solar oven system operates as follows. The operator opens the building opening from the kitchen cooking area and reaches to operate the system with remote control mechanism and devices  120  at the opening bottom edge and retrieves the solar oven system  30  from protective storage for use ( FIG. 2 ). 
     The extendable lever handle  156  end access knob being held in an accessible location with an access knob positioning collar  158 , is pulled vertically straight up fully out of the pivot weldment  40  and then the extendable lever handle  156  is rotated 90 degrees in the sliding drive block pivot yoke  160  into the horizontal position for use as shown in  FIG. 2 . The extendable lever handle  156  is then pulled or pushed sideways left to right, to provide pivoting torque transmitted through the sliding drive block pivot yoke  160  into the wrench drive plug  162  to the pivot weldment  40  by the user which then rotates the extended positioning system  32 , made up generally of the pivot weldment  40 , structural extension assembly  34 , moveable carriage  58 , along with the box solar oven assembly  180 . This moves the solar oven system  30  out of protective storage, away from, and perpendicular to the building wall, in front of the opening for cooking use as in the position shown in  FIG. 2 . The extendable lever handle  156  is then again rotated 90 degrees in the sliding drive block pivot yoke  160  into the vertical position and lowered back down into the pivot weldment  40  putting it into its original storage position when the access knob positioning collar  158  contacts the wrench drive plug  162  for later use and therefore not interfering with the other operational procedures and features. 
     Then the two remote control mechanisms and devices  120  for azimuth and solar altitude are used to align the back-door surface of the box solar oven assembly  180  to be parallel to the wall opening as in  FIG. 2 . 
     The azimuth hand wheel  134  ( FIG. 4 ) and solar altitude hand wheel  146  are rotated individually, each driving it&#39;s two drive shafts, azimuth hand wheel drive shaft  136 , azimuth D-profile drive shaft  142 , solar altitude hand wheel drive shaft  148 , and solar altitude D-profile drive shaft  154 . The D-profile drive shafts  142  and  154  transmit the rotating power coming through the miter gears  140  and  152  to turn worm gear mechanisms  104  and  86  ( FIG. 7 ), respectively. The azimuth worm  106  turns the azimuth worm gear  108  that turns the drive roller shaft  114  which then turns drive roller  116 , thereby turning the azimuth 12 inch bearing  250  for azimuth positioning of the box solar oven assembly  180 . 
     The solar altitude worm  88  ( FIG. 8 ) turns the solar altitude worm gear  90  which turns the cable winch drum and shaft assembly  94 , which then, when rotating, pulls the cable winch cable  100  in a linear direction causing the box solar oven assembly  180  to rotate into the desired solar altitude position. 
     The operator then rotates the linear hand wheel  122  ( FIG. 3 ), therefore turning the cable drive spool  124  and pulling the carriage drive cable  130  which, in turn, moves the box solar oven assembly  180  which is on the moveable carriage  58  and pulls it towards and up to the wall opening ready for use. 
     The door assembly  218  is then pulled out of the box solar oven assembly  180  and temporarily positioned somewhere in the food preparation area until later use (if a hinged door design is used than this no longer applies). The prepared food containers are then loaded and positioned on the food rack horizontal plate  240  ( FIG. 11 ) being stacked or positioned to the desired liking. The door assembly  218  is then reinserted back into the box solar oven assembly  180 , therefore closing the box solar oven  180  for the cooking operation. 
     Again, rotating the linear hand wheel  122  ( FIG. 3 ) deploys the loaded box solar oven assembly  180  out into the open environment by pulling the moveable carriage  58  out to the end of the extended positioning system  32 . The wall mount system  164  ( FIG. 2 ) provides the necessary strength to accommodate the deployed loaded box solar oven assembly  180  out away from the building structure by all vertical load forces directed down in the ground foundation block  178 , horizontal loading held in equilibrium by the pivot post  174  and pivot post straps  176 , pivot post saddle weldment  166 , pivot weldment  40 , and beam suspension support truss assembly  48 . The azimuth hand wheel  134  ( FIG. 4 ) and solar altitude hand wheel  146  are now rotated again by the operator to align the box solar oven assembly  180  in position (towards the sun) for optimum solar energy retrieval. As the azimuth hand wheel  134  and solar altitude hand wheel  146  are now being rotated, the operator visually uses the light alignment indicator assembly  256  ( FIG. 13 ) and the light beam spot on either side of translucent target  264  to indicate and communicate the amount of azimuth and solar altitude adjustment alignment required for the box solar oven assembly  180  with respect to its related perpendicularity of the glazier surface to the sun&#39;s incoming rays. 
     Solar cooking is now in full operation without spillage, leaving the kitchen, or other deployment problems associated with the prior art. Now, periodically, the user visually checks and monitors the light alignment indicator assembly  256  translucent target  264  light beam alignment patterns and makes the desired necessary adjustments using the azimuth hand wheel  134  and solar altitude hand wheel  146  keeping the oven system collecting the greatest quantity of solar radiation. The indication of light rays which pass through the light indicator tube onto the translucent target  264  in a full round spot (not round or clipped off) indicates that the box solar oven assembly  180  is accurately aligned to the sun for optimum perpendicularity, therefore, energy retrieval. 
     As an alternative embodiment ( FIG. 6 ), this manual solar adjustment and alignment process with azimuth hand wheel  134  and solar altitude hand wheel  146  can be configured to be semiautomatic or fully automatic by installing sun tracking devices to the azimuth and solar altitude control mechanisms such as clock motors on each hand wheel, weather spring driven or electric, or other apparatuses to rotate and track the sun path as needed with feedback or no feedback. This tracking would be operated after the above deployment with the manual controls to a sun path start position for the day or cook time. 
     When the cooking process is completed, the azimuth hand wheel  134  and solar altitude hand wheel  146  are then rotated by the operator to align the back-door surface of the box solar oven assembly  180  to be parallel to the wall opening as in  FIG. 2 . Then the operator again rotates, the linear hand wheel  122 , therefore turning the cable drive spool  124  and pulling the carriage drive cable  130  which moves the box solar oven assembly  180  back towards and up to the wall opening ready for unloading. The door assembly  218  is then pulled out of the box solar oven assembly  180  and temporarily positioned somewhere in the food preparation area until later (if a hinged door design is used than this no longer applies). The prepared food containers are then unloaded back into the cooking area by removing them off the food rack horizontal plate  240 . The door assembly  218  is then reinserted back into the box solar oven assembly  180 , therefore closing the box solar oven  180  for storage. 
     Then the operator again rotates, the linear hand wheel  122 , therefore turning the cable drive spool  124  moving the box solar oven assembly  180  back out away from the building wall and again pulls up extendable lever handle  156  end access knob which is pulled vertically straight up fully out of the pivot weldment  40  and then retracted back down 90 degrees in the sliding drive block pivot yoke  160  into the horizontal position for use pivoting the solar oven system  30  to the protective storage area for later use. The azimuth hand wheel  134  and solar altitude hand wheel  146  may be rotated by the operator to align the box solar oven assembly  180  under the protective storage shelter cover  268  ( FIG. 1 ). 
     The center of gravity biaser spring  252 , screwed to the plate  244  surface, keeps the solar altitude cable winch cable  100  constantly tight throughout the entire 90-degree rotation range when the altitude position is high enough to shift the center of gravity moment in reverse (a geometric characteristic of the oven shape). The center of gravity biaser spring  252  ( FIG. 3 ) pushes on the bottom of the box solar oven assembly  180  upward therefore removing or eliminating the reverse force moment and maintaining the forward force moment (biased in one direction), therefore keeping cable winch cable  100  remaining tight and fully operational in any position without losing control due to cable  100  slack. 
     The solar altitude locking bar  254  ( FIG. 12 ) is connected with a pivoting screw onto the box solar oven assembly  180  and slides in a slot at the yoke member  228  when the box solar oven assembly  180  is rotated. By tightening a locking finger screw (not shown) in the long solar altitude locking bar  254  slot, a clamping action of the solar altitude locking bar  254  to the yoke member  228  occurs, therefore locking the box solar oven assembly  180  into a set position. This is used for manually locking the rotating altitude position when needed during handling, maintenance, or assembly of the system. 
     The solar oven system embodiment provides a highly efficient, effective, and adaptive solar oven cooking apparatus that is easy for anyone to frequently use as a useful cooking device when doing standard ongoing cooking operations. 
     Reaching out away from the building structure into the outside environment for solar exposure when operated with remote controls without leaving the cooking area, and the adaptable flexible universality of the system features greatly enhancing practicality and usability, all provide increased significant development of solar oven technology in the prior art, therefore, substantially impacting energy savings, alternative energy use, and energy conservation. 
     The solar oven system embodiment provides a major advantage of integrating the needed solutions of the various and numerous problems encountered with solar cooking that, up until now were prohibitive to the operating requirements of each step in the entire solar cooking process. It is one complete seamless cohesive operation that has been solved with this new embodiment apparatus by integrating the functional process steps together from a kitchen area. 
     Featured examples of this new embodiment including the box solar oven structure rotating around the food contents during vertical solar altitude adjustments, all food handling being done in the kitchen area, and the ability to move out and position the box solar oven out away from the building and retrieve it back from inside the building are just three of the major advantages illustrating the practical innovative design of this embodiment. 
     In addition to the above-described embodiments, many other variations are possible. For example, solar oven system  30  and or extended positioning system  32  may be used for other food preparation needs such as cooling of hot dishes, making sun tea, drying fruit, drying dishes, or pasteurizing water. 
     The extended positioning system  32  may be used alone to adapt to and accommodate other portable box solar ovens built or purchased which are unrelated generic types to this solar oven system. If yoke member  228  ( FIG. 12 ) is disconnected from the azimuth 12 inch bearing top mount plate  244 , therefore enabling removal of the remainder of the box solar oven assembly  180 , then any portable solar oven placed on top of the azimuth 12 inch bearing top mount plate  244 , which is connected to the moveable carriage  58 , would provide for the operator to be able to use three of the manual remote control mechanisms and devices  120 , including the Linear hand wheel  122  for carriage movement, azimuth hand wheel  134  for adjusting azimuth, and the extendable lever handle  156  for polar angular rotation of the structural extension  34 . This adaptation provides for expanded use of the described embodiment utilizing a wider range of market adaptations of generic prior art portable box solar ovens which further accelerates solar oven technology in the future. 
     The extended positioning system  32 , with its universal utility including its manipulating and control features, may also provide other wider uses such as photo voltaic solar cell positioning and operation, or other applications requiring extension and reach out away from buildings or other structures. 
     This embodiment, with its utility, can be adapted and reconfigured at the wall mount by eliminating the ground foundation block  178  loading path for multistory, above ground building and apartment use applications providing access to sunlight to residences and the like for solar cooking operations that would not normally be available to these applications. This further expands the solar oven technology. 
     Furthermore, the solar oven system  30  may also be used and mounted at any alternative location of the building structure, deck structure, wall, or post for added utility in various adapted settings. This will expand the alternatives available for solar radiation exposure. 
     Further, the option of creating a new cut wall opening designated solely for this solar oven system  30  provides the added benefit of having the box solar oven assembly  180  protective storage shelter cover  268  over and around the opening for ease and effective storage when pulled back to the building when the unit is not in use (not blocking a window opening when leaving the unit ready for the next use). Also, a new designated opening can provide better operator reach into the box solar oven  180  depending upon the interior layout of the cooking area. The protective storage shelter cover  268  can also be installed directly over and around the window opening if desired for ease and speed of the operation regarding the unit storage steps being removed. 
     Box solar oven assembly  180  can also be used and operated in a standalone configuration in the described embodiment placed anywhere such as a prior art portable unit and can be aligned by rotating manually then locked into position using the solar altitude locking bar  254  ( FIG. 12 ). 
     Another variation of an embodiment of the solar oven system  30  would be to have the extended positioning system  32  structural extension assembly  34  lengthened for further reach out into the environment for solar radiation availability providing (if out far enough) approaching 360 degrees of solar exposure. By adding a section to the structural extension assembly  34  or having a telescoping section that extends out from the main structural extension  34 , this could be accomplished. Due to the extensive structural extension length, a designed support assembly with wheel casters extending down to the ground or other surface and attached at some intermediate location along the structural extension  34  or at an end of structural extension  34  would provide added support for a long structural extension  34  while continuing to provide for movement when making polar angular adjustments of structural extension  34  with the extendable lever handle  156 . 
     Referring to  FIG. 12 , the azimuth bearing and pedestal base assembly  242  can be changed in various ways to provide alternative ways to accommodate different applications and reduce parts and cost. For example, one alternative is to remove (not have) the pedestal base  248  and azimuth 12 inch bearing bottom mount plate  246  whereby then attaching the azimuth 12 inch bearing  250  directly to the moveable carriage base plate  80 . Another is to remove the two top and bottom azimuth 12 inch bearing mount plates  244  and  246  along with the pedestal base  248  and attach the yoke member  228  and moveable carriage base plate  80  directly to the azimuth 12 inch bearing  250  (not removable readily from the extended positioning system  32  and no base for standalone operation). These configurations reduce the amount of parts and cost of the azimuth bearing and pedestal base assembly  242  which are not necessarily required for some stand alone or other application functions. Or, the pedestal base  248  can be attached directly to the yoke member  228  (no azimuth 12 inch bearing  250  or azimuth function unless a separate bearing is inserted under the pedestal base  248 ) for a standalone system (operating without the extended positioning system  32 ). 
     Another variation of the solar oven system  30  is that door assembly  218  can include a hinge and latch design at the top or bottom of the door edge to increase and simplify operation efficiency which keeps the door attached at all times to the oven body and speeds up the loading process. Either design of press fit insertion (described in the above description) or hinged attachment can be used depending on cost and process method application requirements. 
     Different alternative wall mount system design configurations to accommodate various applications include a steel stake retention rod driven into the ground replacing the saddle bottom retaining bracket  172  which was previously employed. This stake retention method includes a horizontal flange (not shown which is welded onto the M-shape saddle  168 ) protruding from one side of the M-shape saddle  168  near the ground surface with a hole for the insertion and driving of a retention rod driving it deep into the ground material for secure retention of the bottom of the pivot post saddle weldment  166 . This design is needed when the building wall design and material do not accommodate the saddle bottom retaining bracket  172  design shown in the preferred embodiment described above. Also, the saddle top retaining stud  170  can be converted to another shape design of a flange with a hole or other for accommodating different building designs. Screws, bolts, other type fasteners, or other standard prior art retaining methods can be used if necessary to attach the pivot post saddle weldment  166  to the wall as well. 
     The azimuth worm gear drive mechanism  104  ( FIG. 7 ) can be changed to a miter gear  90  degree (no gear reduction) or bevel gear (reduction) alternative design if desired. This provides an alternative for a direct drive gear ratio of one to one in the drive system or other gear reduction ratio to the azimuth 12 inch bearing  250 . This reduces the turning revolutions the operator must make to change azimuth position. These designs also allow for cost reduction in manufacture. 
     Sun tracking clock motors, servo motors (spring force, electric, or other), or other server mechanisms can be mounted and attached to the azimuth and solar altitude hand wheel and hand wheel drive shaft assemblies wheels  132  and  144  ( FIG. 2 ) for driving and turning the remote-control devices to track the sun path for automatic adjusting to sun position throughout the day therefore, not requiring operator intervention for the entire cooking time. 
     The positioning system can include a sun tracking system that utilizes servo motors that adjust positioning of the solar oven radiation collection device. For example, a sun location system can be used to identify current location of the sun, and the servo motors (or other servo mechanisms) can adjust positioning of the solar oven radiation collection device based on information about location of the sun provided by the sun location system. 
     For example, a market manufactured automated sun tracking system using either a fixed control algorithm, fixed control mechanism, or dynamic tracking system design can be adapted and integrated into the solar oven system  30  ( FIG. 2 ) by attaching automatic sun tracking system components onto the extended positioning system  32  and box solar oven assembly  180 . Referring to  FIG. 5  and  FIG. 6  servomotors  270  and  274  are mounted to the azimuth hand wheel drive shaft  136  and solar altitude hand wheel drive shaft  148  with azimuth servomotor mount bracket  272  and solar altitude servomotor mount bracket  276  with machine screws or other standard attachment methods. The servomotor drive shafts are connected with azimuth servo drive coupling  280  and solar altitude servo drive coupling  282  with set screws to the azimuth and solar altitude hand wheel drive shafts  136  and  148  for driving the azimuth and solar altitude hand wheel &amp; hand wheel drive shaft assemblies  132  and  144  ( FIG. 2 ). The azimuth and solar altitude servomotor mount brackets  272  and  276  are then attached to azimuth miter gear drive shaft bracket  138  and solar altitude miter gear drive shaft bracket  150  ( FIG. 6 ) with machine screws or another standard attachment method to connect and hold the servomotors stationary with respect to the positioning system  32  frame when rotating. A feedback light sensor unit  278  ( FIG. 11 ) mounted on the translucent target  264  ( FIG. 13 ) under the end of the light indicator tube  260  receives light from the light indicator tube when in alignment communicating to the servomechanism to stay in position, or if partial light, adjust to align. This feedback light sensor unit  278  would be used for a dynamic system design requiring a feedback sensor circuit. A solar tracking controller  284  is then connected to the sensor circuit and servomotors for solar tracking control. 
     Further, servo motors can be employed that position using a GPS (Global Positioning System) control signal from a cell phone or other electronic device. Furthermore, a solar oven system software application on a cell phone could be employed to adjust and monitor temperature and sun alignment by the operator during the cooking process and operations using current telecommunications technology.
