     BACKGROUND OF THE TECHNOLOGY  
      As is apparent from the above discussion, support stands are known, in general, for supporting and/or displaying items such as musical instruments, guitars, and the like. Guitar stands typically support the guitar in an upright or inclined position. Guitar stands usually have a lower part, which cradles the guitar body, and an upper part, which supports the neck or back of the guitar by providing a point or points upon which the neck or back of the guitar rests. Such stands, however, are often large and bulky and are difficult to transport and store. Even when these types of stands are broken down or disassembled, they occupy a large volume or have an awkward shape, which makes them difficult to transport and store. The awkward or bulky disassembled form is also subject to damage during storage or transport, for example, in the case of a traveling musical group.  
      Other stands are known for supporting and/or displaying items such as books, paintings (framed and in progress), placards, signs, display cases, and the like. These stands, in addition to the aforementioned musical instrument stands, are often delicate—in order to save weight or reduce their size. Such stands are easily and irreversibly broken, for example, when accidentally knocked over or stepped upon.  
      Collapsible stands and folding stands are known, but they do not solve the problems outlined above.  
     SUMMARY OF THE INVENTION  
      The present invention solves the above problems, and others.  
      One embodiment of the present invention provides a hinged stand for supporting an article, which includes: 
          a first member that includes a first support recess and a first bearing surface;     a second member that includes a second support recess and a second bearing surface; and     a breakaway hinged connection between the first and second members, which includes: 
            a hinge; and     a first bias to constrain the first and second members at an operational non-zero angle relative to one another about the hinge.    
               

      One embodiment of the present invention provides a hinged stand for supporting an article, which includes: 
          a first member that includes a hinge pin, a first support recess, and a first bearing surface; and     a second member that includes a hook-shaped hinge support, a second support recess, and a second bearing surface;     wherein the hook-shaped hinge support is adapted to receive the hinge pin, the hook-shaped hinge support and hinge pin cooperating to provide a breakaway hinged connection between the first and second members.        

      One embodiment of the present invention provides a method, which includes contacting, supporting, or displaying at least one article selected from the group including a musical instrument, stringed musical instrument, guitar, book, sign, picture, placard, display case, and painting with the hinged stand described above.

     DETAILED DESCRIPTION OF THE INVENTION  
      Various other objects, features, and attendant advantages of the present invention will be more fully appreciated as the same becomes better understood from the following detailed description of the invention, which is not intended to be limiting unless otherwise indicated.  
      The present invention desirably provides a stand that solves the problems with conventional stands. It is particularly suited for supporting and/or displaying any of a musical instrument, stringed musical instrument, guitar, book, sign, placard, display case, and painting (framed or in progress). In one embodiment, the stand is adapted to support and/or display a guitar. The stand is designed to be collapsible for easy storage and/or transport, and when so collapsed it assumes a streamlined profile, which is not bulky or awkward. When closed the stand can desirably fit into an instrument case, such as a guitar case, together with the instrument as appropriate. The stand desirably holds the guitar in an upright or inclined position. When in operation, the stand desirably has a lower part, which cradles the guitar body, and optionally an upper part, which supports the neck or back of the guitar by providing a point or points upon which the neck or back of the guitar rests. Importantly, the stand has a failsafe breakaway hinge feature, which allows the stand to respond to an outside force, such as being stepped upon, without being damaged.  
      In one embodiment, the hinged stand has a first bias to constrain the first and second members  1  and  2  at one or more angles with respect to one another. The angle may be suitably formed substantially between the respective major planes  22  and  23  of the first and second members  1  and  2  and having the hinge axis  20  as the angle vertex. The first bias suitably constrains the first and second members  1  and  2  at a non-zero operational angle with respect to one another about the hinge or hinge axis  20 . This may be referred to herein as the operational or “open” position. The structure of this bias is not particularly limited so long as it has the appropriate function, which, in the context of the present invention, is to constrain the first and second members  1  and  2  at a particular angle, to reproducibly release without damage when subjected to a sufficient additional force, and to reproducibly re-engage without damage for continued use.  
      The stand can be easily opened and closed between its “open” and “closed” positions. The present invention has the particularly desirable feature in that if the stand is stepped on while it is sitting on the floor in its open position, or otherwise subjected to a sufficient angle-opening force, the bias or breakaway hinged connection  9  releases, and the stand can open to a larger angle further and lie flat against the ground. As used herein, the term, “bias” may also be referred to as a bias means, but such terminology should not be interpreted as restricting the invention to any specific structure. The guitar or other supported article may be suitably held in a near-upright or upright position by the stand. The bias constrains the first and second members  1  and  2  with a force sufficient to provide the stand with the structural stability to support the article and not collapse in normal use. When in operation, the first and second members  1  and  2  are in the open position, the first and second support recesses  5  and  6  cradle the article, and the bearing surfaces provide the “feet” or base upon which the stand contacts the underlying supporting surface, such as a horizontal surface or floor. The constraint, however, is not so strong as to prevent a user from easily closing the stand, e.g., for storage or transport, and it is not so strong as to prevent the user from easily opening the stand. In this regard, the user may suitably open and close the stand with one or both hands, pivoting the members about the hinge to any angle as appropriate. However, when the hinged stand, in an operational position, is subjected to an excessive force, such as a downward force, e.g., such as when accidentally stepped upon, the constraining force is overcome, the bias releases the hinge from the operational or other biased angle, and the stand can open to a larger angle, e.g., and lie flat against the ground. This eliminates stress going through the stand and protects it from being damaged. The hinge can thus breakaway without damage to the hinge or stand. Afterwards, the user can simply fold the first and second members  1  and  2  back into the operational position and continue using the stand. Thus, the stand may be easily reassembled for continued use.  
      Nonlimiting examples of the bias include at least one of a catch, pawl, dog, detent, indentation, protrusion  11 , spring, rod  10 , groove, spring detent, snap, hinged strip  30 , hook and loop fabric (e.g., VELCRO™), magnet, or combination thereof on the first member  1 . These components cooperate with one or more appropriate opposing structures on the second member  2 , which may include at least one of a catch, pawl, dog, detent, indentation, protrusion  11 , spring, rod  10 , groove, spring detent, snap, hinged strip  30 , hook and loop fabric (e.g., VELCRO™), magnet, or combination thereof on the second member  2 .  
      In one embodiment, the first bias includes one or more detents on an outside portion of the hook-shaped hinge support  4  in cooperation with a springed rod  10  on the second member  2 , the springed rod  10  having an axis defined by its two ends that is approximately parallel to a central axis  20  of the hinge. In this embodiment, the detents may be a concave portion in an otherwise convex outer surface or profile  19  of the hook-shaped hinge support  4 , or may be defined by two adjacent protrusions  11  on the outer surface or profile  19  of the hook-shaped hinge support  4 , or a combination thereof.  
      In the embodiment having the hook-shaped hinge supports  4  and hinge pins  3  illustrated in figures, the hinge components  3  and  4  may separate upon breaking away. In this embodiment, the user can then simply pick the stand up, engage the hinge pin(s)  3  with the hook-shaped hinge support(s)  4 , fold the first and second members  1  and  2  back into the operational position and continue using the stand.  
      In one embodiment, the first bias may be a hinged strap  30  such as shown in  FIGS. 12, 13  and  14 . The hinged strap  30  suitably includes a hinged portion  32  at some point along its length. The hinged portion  32  may be any hinge, but a living hinge is shown in  FIGS. 12-14 . The hinged strap  30  may be connected to the first and second members  1  and  2  with one or more rotatable features  34 . When the stand is closed, the hinged portion  32  on the hinged strap  30  suitably folds so that it may suitably stow between the closed members  1  and  2 . When the stand is opened, the hinged portion  32  of the hinged strap  30  opens, and the hinged strap  30  controls the bias angle between the members  1  and  2 . The rotatable features  34  allow each leaf of the hinged strap  30  to rotate relative to the surface of the respective first or second member  1  or  2  to which it is attached. One or both of the rotatable features  34  also provides a releasable connection, wherein when a sufficient angle-opening force is supplied to put the hinged strap  30  under sufficient tension, one or both of the rotatable features  34  releases from the respective member  1  or  2  to which they are attached, and the hinge can thus breakaway. One example of the releasable connection for the rotatable features  34  has two or more opposing male bumps  35  on the that snap into two or more respective female indentations  36 . If the stand is stepped on, the male bumps  35  pop out of the female indentations  36 , and the stand can open up and fold flat against the floor. The user can simply re-engage the male bumps  35  with the female indentations  36 , and the stand is ready for reuse. The hinged strap  30 , hinged portion  32 , male bumps  35  and female indentations  36  may be made from any material, e.g., plastic.  
      No other guitar stand has this “breakaway” failsafe hinge feature. The present invention, however, is not limited to guitar stands, and may desirably be extended to and incorporated in other stands as appropriate, and these other embodiments are within the present invention.  
      Any hinge may be suitably used in the stand in accordance with the present invention. One example of a suitable hinge is the combination hook-shaped hinge support/hinge pin illustrated in the figures. The invention is not limited thereto, however. Other suitable hinges include a living hinge, a cloth living hinge, a fibrous living hinge, a plastic living hinge, a hinge having interspersed hinge supports joined by one or more hinge pins, butt hinge, butterfly hinge, flush hinge, barrel hinge, concealed hinge, continuous or piano hinge, slip hinge, flag hinge, combinations thereof, and the like. The hinge supports may have any shape sufficient to pivot around one or more hinge pins, including loop, cylindrical or hook-shaped. The hinge may be formed as an integral part of the first or second members or both, or the hinge may be attached to the members by one or more of adhesive, weld, ultrasonic weld, heat weld, solvent weld, fastener, screw, rivet, mechanical snap, combinations thereof, and the like. If appropriate, each side or “leaf” of the hinge, or the first and second members may be independently swaged or unswaged relative to the hinge axis. Such swaging may be half swage, full swage, or offset as appropriate. The hinge may be reverse assembled as appropriate. In one embodiment, a living hinge includes one or more thin sections of plastic that form a flexible hinged connection between the first and second members. The plastic living hinge material may be a flexible plastic such as polypropylene, polyethylene, nylon, polystyrene, their copolymers, combinations thereof, and the like. Combinations of hinges and hinge materials are possible.  
      One example of a hinged stand with a living hinge is shown in  FIGS. 12, 13 , and  14 .  
      One embodiment of the present invention provides a hinged stand for supporting an article, which includes: 
          a first member  1  that includes a hinge pin  3 , a first support recess  5 , and a first bearing surface  7 ; and     a second member  2  that includes a hook-shaped hinge support  4 , a second support recess  6 , and a second bearing surface  8 ;     wherein the hook-shaped hinge support  4  is adapted to receive the hinge pin  3 , the hook-shaped hinge support  4  and hinge pin  3  cooperating to provide a breakaway hinged connection  9  between the first and second members  1  and  2 .        

      In one embodiment, the breakaway hinged connection  9  includes a first bias to constrain the first and members at an operational non-zero angle relative to one another having the hinge pin  3  at its vertex. In this embodiment, the breakaway hinged connection  9  is designed such that it is biased at a non-zero angle when the stand is in operation, e.g., supporting an article such as a guitar.  
      Nonlimiting examples of first and second members  1  and  2  are shown in  FIG. 1 .  
      Detail of one embodiment of a first member  1  is shown, for example, in  FIG. 2 . The hinge axis  20  is shown along the axial portion of the hinge pin  3  side of the breakaway hinge. Flats  13  are present on several of the knuckles  17  to allow a wire rod  10  to enter a slot  12 , also shown. The springed rod  10  is one part of one example of a bias.  
      One embodiment of a second member  2  is shown, for example, in  FIG. 5 . The section in  FIG. 5A  shows a detail of a hook-shaped hinge support  4 . The inner recess  14  thereof has a hook shape, and the outer surface  19  thereof is suitably convex. Detents are shown on the outer surface thereof, and two wire rod  10  locations  24  and  25  are shown, which correspond to “open” and “closed” locations. The “open” location  24  is one which biases the first and second members  1  and  2  at a non-zero angle relative to each other. This is one embodiment of the operational position. The other “closed” location  25  corresponds to the position of the wire when the first and second members  1  and  2  are biased in a closed position, or are effectively at an approximate angle of zero degrees with respect to each other. This closed location  25  is suitable for when the hinge is being stored or transported.  
      In one embodiment, the non-zero operational or open angle may be suitably between zero and 140 degrees such that when the first and second members  1  and  2  are so biased, the first and second support recesses  5  and  6  cooperate to support the article. When the first and second members  1  and  2  are biased at the non-zero angle, the first and second bearing surfaces cooperate to support the hinged stand. The non-zero angle may include any angle such as 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 27, 30, 40, 45, 50, 60, 70, 80, 90, 100, 110, 120, 130, and 140 degrees as appropriate. In one embodiment, the operational angle is between zero and 90 degrees.  
      The hinged stand can also include more than one bias, including one that constrains the first and second members  1  and  2  at an approximately zero degree angle with respect to one another about the vertex. In another embodiment, in addition to constraining the hinged stand to the operational non-zero angle, the bias constrains the first and second members  1  and  2  at an angle larger than the operational angle, including 180 degrees or larger. More than one bias may be present, and any bias may be used in combination. In one embodiment wherein hook-shaped hinge supports  4  and hinge pins  3  are used such as illustrated in the figures, the bias can be any angle between zero and an angle at which the hinge pin  3  may be removed from the hook-shaped hinge support  4 .  
      In the case wherein a plurality of hinge supports  4  are present, adapted as they are to receive a plurality of hinge pins  3 , then one, more than one, or every hinge support  4  may include at least one bias to constrain the first and second members  1  and  2  at the operational angle or closed angle. A single hinge support  4  may be suitably adapted to create at least one component of the bias. Any of a plurality of hinge supports  4  may be so adapted, and the single hinge support  4  so adapted may appear anywhere along the hinge axis  20 . Mechanically, it may be advantageous to add the hinge bias wherever the hinge has the largest diameter. This enables the bias to be most effective, since it acts at the longest possible torque arm. In the illustrated embodiment, the single hinge support  4  so adapted is located at a central location along the hinge axis  20 .  
      The hook-shaped hinge support  4  has an outer portion or profile  19  and a hook-shaped inner recess, so that the inner recess adapted to receive the hinge pin  3 . The recess may be suitably adapted to receive the hinge pin  3  at a right angle to its central axis, e.g., at a right angle to the hinge axis  20 .  
      In one embodiment, the first member  1  of the stand may suitably include a plurality of hinge pins  3 , separated and supported by hinge pin knuckles  17 . These plural pins have a common central axis, or hinge axis  20 .  
      In one embodiment, the second member  2  may also include more than one hook-shaped hinge support  4 . These, too, have a common central axis  20 , and are adapted to receive a plurality of hinge pins  3 .  
      The knuckles  17  supporting the hinge pins  3  may have any outer profile  18 . Similarly, the outer profile  19  of the hook-shaped hinge support  4  may have any shape. The outer profiles  18 ,  19  of the knuckles  17  and/or hook-shaped hinge supports  4 , and any individual knuckle  17  or support thereamong, may each be independently circular, elliptical, parabolic, polygonal, triangular, square, pentagonal, hexagonal, heptagonal, octagonal, and any combination thereof, when viewed in section along the hinge axis  20 . If a plurality of hinge pins  3  and hook-shaped hinge supports  4  are present, they may have the same outer perimeters or diameters as the case may be, or their perimeters or diameters may vary along the length of the hinge axis  20 . In one embodiment, such as substantially shown in the figures, the centrally located knuckles  17  and hook-shaped hinge supports  4  have outer perimeters that are larger than those at the ends of the hinge axis  20 . This gives the hinged connection a pleasing arcuate shape.  
      One example of a first member  1  is shown, for example in  FIG. 4 . The section in  FIG. 4A  shows a detail of one hinge pin  3  and knuckle  17 . The bumps  15  as shown form an inner wall that limits the wire rod  10  flex direction. The section A-A detail shows two surfaces that create a slot  12  in which the wire rod  10  is allowed to flex. The slot  12  is suitably adapted to secure the wire rod  10  in place in the event the first and second members become separated. This eliminates the possibility that the user might lose the wire rod  10  if it were to fall out when the first and second members are separated.  
      In one embodiment, the breakaway hinge connection includes an axial portion with first and second ends thereof, the first end being adjacent to the first and second support recesses  5  and  6 , and the second end being adjacent to the first and second bearing surfaces; and wherein the first end provides an additional support surface  21  that cooperates with the first and second recesses for supporting the article. In another embodiment, the breakaway hinged connection  9  includes an axial portion with first and second ends thereof, the first end being adjacent to the first and second support recesses  5  and  6 , and the second end being adjacent to the first and second bearing surfaces; and wherein the second end provides an additional bearing surface that cooperates with the first and second bearing surfaces to support the hinged stand in an operational position.  
      As noted above, the breakaway hinged connection  9  is adapted such that the first and second members  1  and  2  may be moved from the operational non-zero angle to an angle of approximately 180 degrees and greater without damaging the stand. In addition, the breakaway hinged connection  9  may be suitably adapted such that the first and second members  1  and  2  may be repeatedly moved from the operational non-zero angle to an angle of approximately 180 degrees and greater and back to the operational non-zero angle without damaging the stand.  
      In one embodiment, the first and second members  1  and  2  may be repeatedly moved through any angle between zero and 360 degrees without damaging the stand.  
      In one embodiment, the breakaway hinged connection  9  may suitably be adapted such that the first and second members  1  and  2  may be repeatedly moved from the operational non-zero angle to a larger angle and separated from one another, the hinge pin  3  being removable from the hook-shaped hinge support  4  at the larger angle, and the first and second members  1  and  2  may be unhinged accordingly.  
      In one embodiment of the present invention, the breakaway hinge is adapted such that the first and second members may not be unhinged from one another. This embodiment has the advantage that the user would not need to realign the hinge pin  3  to the hook-shaped hinge support.  
      In one embodiment, the hinged stand includes a separate structure for holding the first and second members  1  and  2  in a closed position, such as a snap closure, hook and eye closure, magnetic closure, hook and loop (e.g., VELCRO™) closure, and the like.  
      In one embodiment of the invention, when the first and second members  1  and  2  are open in an operational position, the stand assumes a roughly tetrahedral shape, with one face of the tetrahedon substantially defined by the bearing surfaces (e.g., the intersection of the bearing surfaces with a horizontal surface upon which the stand rests); one face substantially defined by the major plane  22  of the first member  1 ; one face substantially defined by the major plane  23  of the second member  2 ; and a fourth face of the tetrahedron substantially defined by a major plane of the supported instrument or, alternatively, by a plane intersecting the additional support surface  21  and the frontmost projections of either the bearing surfaces  7  and  8  or the support recesses  5  and  6 . In this manner, the hinge axis  20  substantially defines one edge of the tetrahedron, which is inclined with respect to the horizontal surface and which forms a load-supporting axis. If appropriate, at the uppermost end of the load-supporting axis is the additional support surface  21 , and a bearing surface is at the lowermost end of the load supporting axis.  
      The assembly procedure for the stand is not particularly limited. In one embodiment, a small plastic tube  16  is slid over a springed wire rod  10  to minimize abrasion between the wire rod  10  and the plastic hinge. This tube  16  may or may not be necessary depending on the different materials used for the different parts, which may be selected according to the skill of the ordinary artisan. The wire rod  10 , with the plastic tube  16  located at the center of the rod  10 , is dropped down into its slot  12  in the first member  1 . The second member  2  is then dropped down onto the first member  1 , with the inner recess  14  of the hook-shaped hinge support on the second member  2  aligned with the hinge pin on the first member  1 . As the second member  2  is rotated towards the “closed” position, the wire rod  10  pops over the protrusions  11  on the center hinge knuckle  17  that create the “detent” feature.  
      The stand may be easily opened and closed. If the stand is stepped upon while it is sitting on the floor in its open position, the wire can pop over the center hinge knuckle  17  protrusion  11  and the stand can open and fold flat against the ground. This eliminates stress going through the stand and protects it from being damaged. The user can then simply pick the stand up, engage the hinge pin(s)  3  with the hook-shaped hinge support(s)  4 , and fold the first and second members  1  and  2  back into the operational position and continue using the stand.  
      The material forming the stand is not particularly limited. The stand may suitably be made of a plastic, metal, wood, or composite material, or any combination thereof. In one embodiment, the stand is made of plastic.  
      In one embodiment, each member of the stand includes a main plastic body which may have one or more rubber-like cushions  26  attached to it. In one embodiment, three cushions are used on each member, with two of the cushions  26  provide padding between the stand bearing surface and the floor, and one of the cushions  26  provides padding between the stand support recess and/or support surface and the instrument or article.  
      The cushions  26  can be made from any reasonably soft material which will not mar the finish on the guitar or floor. The material should be soft enough to protect the guitar finish and prevent the guitar from slipping in the stand. Suitable materials include silicone, rubber, vinyl, polyisoprene, TPE™, or KRATON™.  
      One embodiment is shown, for example, in  FIG. 3 , wherein the elastomeric cushions  26  are attached to the bearing surfaces and recess supports by hard plastic rails  27 . The hard plastic rails  27  may be welded, ultrasonically welded, heat welded, or solvent welded down over the elastomeric cushions  26  to secure them in place. Alternatively, the rails  27  can be affixed using adhesive, screws, rivets, mechanical snaps, or other means, or any combination thereof. In view of cost efficacy and bond strength, ultrasonic welding may be advantageous. Alternatively, the cushions  26 , without the rails  27 , can be directly affixed using adhesive, screws, rivets, mechanical snaps, or other means, or any combination thereof.  
      Another embodiment of the present invention provides a method, which includes contacting, supporting, or displaying at least one article selected from the group including a musical instrument, stringed musical instrument, guitar, book, sign, display case, picture, placard, and painting with the hinged stand described above.  
      The present invention is not limited to only the breakaway hinges shown. Other types of breakaway hinges may be suitably used in accordance with known manufactures.  
      Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically recited herein.
