     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to the field of shades. More particularly, the present invention relates to portable sunshade apparatus which can be used by itself or removably attachable to a variety of different sizes and styles of recreational chairs or the like through use of a novel attachment mechanism. 
     2. Description of the Prior Art 
     Over the years, various sunshade devices have been developed for providing shade to sunbathers or the like. Conventional umbrella-type devices are still widely used by beachgoers, homeowners, and commercial establishments such as restaurants, hotels and resorts, as a means to provide shade to the user against the sun&#39;s rays. One problem with umbrella-type devices is that they are bulky and inconvenient for transporting them to the beach or other locations which require shade from the sun&#39;s rays. Another problem with these umbrella-type devices is that they are difficult to adjust as the sun changes locations in the sky during the course of the day. Another prior art shade is a ground supported shade having an adjustable canopy but has proven to be inflexible since the user may during one portion of the day, desire to lie upon the beach sand, while during another portion of the day prefer to sit in a beach chair. The prior art ground supported canopy is not adaptable to use on a beach chair.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
     Referring to FIG. 1, there is shown at  12  a support member of the present invention portable sunshade apparatus  10  which is shown with all of its components in FIG.  3 . The support member  12  comprises a U-shaped upper frame  14  and a U-shaped lower frame  16 . The upper frame  14  has a pair of parallel legs  18  which are spaced apart by a cross-bar  24 . Each leg has a curved distal end  20  which extends downwardly and a proximal end  22  which is integrally connected to the cross-bar  24 . The lower frame  16  has a pair of parallel upper hollow legs  26  which are spaced apart by a cross-bar  32 . Each upper hollow leg  26  has a proximal end  28  which is hingeably connected to a respective one of the pair of parallel legs  18  of the upper frame  14  and a distal end  30  which is integrally connected to the cross-bar  32 . 
     Referring to FIGS. 1,  2 ,  3  and  4 , there are provided a pair of elongated lower extendable and retractable insert legs  34  or telescopic legs which are inserted into the distal ends  30  of the upper hollow legs  26  of the lower frame  16 . These lower insert legs  34  can be adjusted by loosening threaded knobs  36  which are threadedly engaged with the sides of the upper hollow legs  26  for adjusting the height of the support member  12 . When the lower insert legs  34  are adjusted to the desired vertical position, the lower ends of the lower insert legs  34  are then inserted into the beach sand such that the support member  12  stands in a generally vertical position (see FIG.  7 ). 
     Referring to FIGS. 3 and 4, there is provided an upper semi-flexible canopy member  40  which is sized to fit the width of the upper frame  14  of the support member  12  which is attached thereto by conventional means, so that the canopy member  40  can extend outwardly from the support member  12  in a generally horizontal position to cover and protect a person  2  lying on the ground below the canopy member  40 , such as from the sun&#39;s rays (see FIG.  7 ). There is also provided a lower semi-flexible canopy member  42  which is sized to fit the width of the lower frame  16  of the support member  12  which is attached thereto by conventional means and is in a generally vertical position. 
     Referring to FIG. 4, the support member  12  of the portable sunshade apparatus  10  can be folded when not in use for storage, by pushing the upper and lower frames  14  and  16  inwardly toward each other such that the two canopy members  40  and  42  abut each other. 
     Referring to FIG. 8, there is shown the present invention portable sunshade apparatus  10  which can be used as a head support. The portable sunshade apparatus  10  is positioned at an angle, similar to an “A-shape” in the cross-section view. The lower ends of the lower insert legs  34  are positioned into the beach sand while the distal ends of the upper frame  14  are also positioned on the beach sand, thereby allowing the user&#39;s head to be supported by the canopy member  40  as shown. 
     Referring to FIGS. 5 and 9, there is shown one of the pair of removable attachable mechanisms  46  for securing it to the side of a typical outdoor beach chair or the like (see FIG.  9 ). The removable attachable mechanism  46  comprises a C-shaped snapping tube  48 , an inner hollow holding tube  50  and an outer hollow holding tube  52 . The inner and outer hollow holding tubes  50  and  52  are permanently affixed to each other in the longitudinal direction so that they will not move or rotate on their axis. The C-shaped snapping tube  48  is rotatably connected to the inner hollow tube  50  such that it can rotate 360° on its axis. Each removable attachable mechanism  46  is for removably attaching to a side of a beach chair  60  or the like, so that the support member  12  can be held about the chair  60  for providing shade to the user sitting on the chair. The lower insert legs  34  are respectively inserted either to the inner or outer hollow holding tubes  50  and  52 . In this illustration, the lower insert legs  34  are inserted into the inner hollow holding tubes  50  as shown in FIG.  9 . However, if the beach chair  60  was smaller in size, then the lower insert legs  34  would be inserted into the outer hollow holding tubes  52 . 
     It will be appreciated that the removable attachable mechanism  46  can be attached to any device that has side tubular members for the C-shaped snapping tube  48 , so that the portable sunshade apparatus can be used with other sitting devices not shown. 
     Referring to FIG. 10, the portable sunshade apparatus  10  can be used as a storage hook. The portable sunshade apparatus  10  is in its unfolded condition and is suspended from the wall  62  for receiving and retaining the beach chair  60  as shown. 
     The present invention conforms to conventional forms of manufacture or any other conventional way known to one skilled in the art, and is of simple construction and is easy to use. 
     Referring to FIGS. 12 through 15, there is illustrated the novel attachment means  110  of the present invention. The novel attachment means has at its front end an openable clamshell bracket member  120  having a multiplicity of parallel arcuate members. In the illustrated embodiment, two sets of parallel arcuate members are illustrated. There is an outer parallel arcuate member  122  having a first elongated arcuate wall  124  and a parallel and mating second and elongated arcuate wall  126 . Adjacent and interiorly located relative to the outer parallel arcuate member  122  is an inner arcuate member  128  having a first elongated arcuate wall  130  and a parallel and mating second elongated arcuate wall  132 . 
     The openable clam shall bracket member  120  has two halves, a first half  140  having first outer elongated arcuate wall  124  and first inner elongated arcuate wall  130  and an internal wall  142 , and a second half  144  having second outer elongated arcuate wall  126  and second inner elongated arcuate wall  132  and an internal wall  146 . 
     The first half  140  and the second half  144  are rotatably connected at their mating end by rotational attachment means  148 . A first closing means which by way of example can be a threaded bolt  150  having a knob  152  and threads  154  can be unscrewed causing first half  140  and second half  144  to be rotated away from each other so that the bracket is open as illustrated in FIG.  15  and can be threaded closed so that the first half  140  and second half  144  can be brought closed together to clamp onto a side of a chair, as illustrated in FIGS. 11 and 12. 
     The novel attachment means further comprises a rotatable ratchet member  160  with a first set of teeth  162  and a mating second set of teeth  164 . As illustrated in FIGS. 13,  14  and  15 , the first set of teeth  162  are located on the first body member  170  which extends transversely from the outer surfaces of the second outer elongated arcuate wall  126  and the second inner elongated arcuate wall  132 . The second set of teeth  164  are located on a separate second body part  172 . 
     The first body part  170  and the second body part  172  are connected together by a second closing means  180  which by way of example can be a thread bolt  180 . The teeth  162  and  164  are brought into mating alignment and attached together by the threaded bolt  180 . Since the first set of teeth  162  and the second set of teeth  164  each extend for 360 degrees, the orientation of the first set of teeth  162  onto the second set of teeth  164  can be at any angle. 
     The second body part  172  is attached to a cylindrical leg receiving member  186 . Due to the 360 degree orientation of the mating teeth  162  and  164  of ratchet member  160 , the cylindrical leg receiving member  186  can be rotated to any desired angle relative to the first body part  170  and the openable clamshell bracket member  120 . As illustrated in FIG. 14, the second closing means can be opened by rotating the head  182  of the thread bolt  180  counterclockwise so the threads  184  (not shown) of the second thread bolt  180  enable the teeth  162  and  164  to be separated and rotated relative to each other to enable the cylindrical leg receiving member  186  to be oriented at any angle relative to the openable clamshell bracket member  120 . 
     The cylindrical leg receiving member  186  has an adjustment means  190  which extends through a threaded opening  188 . The adjustment means  190  can be a threaded bolt  190  having a head  192  and threads  194  which extend into the hollow interior  187  of the cylindrical leg receiving member  186  as illustrated in FIG.  15 . Therefore, the vertical leg  292  of the sunshade apparatus can be inserted into the cylindrical leg receiving member  186  and adjusted to any desired height by tightening the adjustment means  190  so that the sunshade apparatus leg  292  is tightly pressed against the interior wall  189  of the cylindrical leg receiving member  186  at the desired location. 
     The attachment means can be made of any material which is plastic or metal. 
     The present invention also comprises a portable and collapsible sunshade apparatus  200  illustrated in FIGS. 16 through 19. The collapsible sunshade apparatus comprises a first horizontal bar  202  and a spaced apart parallel second horizontal bar  204 . The first and second parallel horizontal bars are maintained in their parallel horizontal orientation by a pair of spreading bars. First spreading bar  206  comprises a first arm  208  and a second arm  210  which are rotatably jointed at their overlapping interior ends by a locking rivet  212 . First arm  208  has an exterior end  214  which is rotatably attached to first horizontal bar  202  by a locking rivet  218 . First arm  208  also has an interim end  216 . Second arm  210  has an exterior end  220  which is rotatably attached to second horizontal bar  204  by a locking rivet  222 . Second arm  210  also has an interior end  224 . First and second arms  208  and  210  are rotatably joined at their interim ends by locking rivet  212 . 
     As illustrated in FIG. 17, the first spreading bar  206  is located adjacent the interior end  198  of horizontal bars  202  and  204 . Located in spaced apart parallel relationship to the first spreading bar  206  but positioned adjacent the exterior end  196  of the horizontal bars  202  and  204  is a second spreading bar  236 . Second spreading bar  236  comprises a first arm  238  and a second arm  240  which are rotatably joined at their overlapping interior ends by a locking rivet  242 . First arm  238  has an exterior end  244  which is rotatably attached to first horizontal bar  202  by a locking rivet  248 . First arm  238  also has an interior end  246 . Second arm  240  has an exterior end  250  which is rotatably attached to second horizontal bar  204  by a locking rivet  252 . Second arm  240  also has an interior end  254 . First and second arms  238  and  240  are rotatably joined at their interior ends by locking rivet  242 . 
     First horizontal bar  202  is attached adjacent interior end  198  to a first support bracket  260  and second horizontal bar  204  is attached adjacent its interior end  198  to a second support bracket  262 . In the preferred embodiment, they are permanently attached by attachment means such as rivets  264 ,  266 ,  268  and  270  respectively. 
     Extending perpendicularly to first horizontal bar  202  is first vertical leg  280 . At its interior end  282 , first vertical leg  280  is rotatably attached to first support bracket  260  by a horizontal bar  284  which extends through the first vertical leg  280  and through the first support bracket  260  and which horizontal bar  284  terminates or ends in caps  286  and  288 . A rivet pin  290  extending interiorly of at least one wall of the first support bracket forces first vertical leg  280  to be maintained in its vertical orientation. A rotational force can move the first vertical leg  280  past the rivet pin  290  to cause it to be folded against first horizontal bar  202  as illustrated in FIG.  18 .
