CROSS-REFERENCES TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. provisional patent application No. 62/058,285 that was filed on Oct. 1, 2014. The disclosure of this provisional application is expressly incorporated by reference herein. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The disclosed invention generally pertains to a collapsible sign. More specifically, the invention pertains to a Ninja Sign having an open arm span that is substantially larger than that of the closed arm span, thus allowing the open frame to hold a much larger sign face than the closed frame; it also allows the sign frame to be stored and transported more easily. The face of the sign can be made to collapse as well thus further reducing the over-all size of the stored sign. Among other uses, the Ninja Sign is great for residential and commercial real estate agents, and it is not limited to outdoor applications. 
       BACKGROUND OF THE INVENTION 
       [0003]    In many instances companies or individuals like to take advantage of yard space to advertise various campaigns, sales, or business related events; often times this is done via transportable signs. Yard signs come in all shapes, and designs, but what is important for most signs are the aesthetics, elevation height of the face, and ease of use. Signs that are too low can become hidden by grass, or small bushes that render the sign less useful, while a lack of aesthetics can often times indicate a lack of professionalism of the company or individual that it is advertising. Most yard signs are bulky and hard to fit in the average size vehicle; they can be inconvenient to reuse because they are not compact enough to store efficiently for the next use. Thus, many larger signs simply have a one-time use. 
         [0004]    It is quite common for business personnel, such as real estate agents, to have to set up multiple yard signs on a daily basis. To do so, the signs must first be transported to the selected site, which typically requires that the agent try and fit several large signs in their vehicle without causing scratches or dents. Simply placing multiple signs in a vehicle can allow for the signs to rattle against each other making it very difficult to communicate with clients that are in the vehicle with you, and causing damage to the signs. Not to mention that the size of the sign is often times very limited by the size of the vehicle carrying it. 
         [0005]    Once at the desired location, the sign must either be set on the ground and left, which means that the sign must be heavy enough to not blow away, or it must have stake(s) that go into the ground. The heavier sign obviously makes it less user friendly, while putting stake(s) in the ground can be rough on the sign frame; this is because often times the stake(s) are part of the sign frame itself with no direct hitting point except for the top of the sign frame. Thus putting the stake(s) in hard ground can require that you hammer on the frame, which causes unwanted damage. Not to mention that many signs require additional tools that take up space, and inconvenience the user. 
         [0006]    Many yard signs are large which can require the user to maintain a storage shed. Often times, in the real estate industry, yard signs are simply left outdoors leaning against the company building simply because the signs are not compact enough to store inside without a shed. 
         [0007]    It is desirable to provide an easy to use sign that can be more conveniently stored, in the form of a Ninja Sign. Although Ninja Signs come in multiple sizes, the design can allow for the user to transport over 10 commercial size signs in the average size trunk. Ninja Signs can be aesthetically pleasing, and easy to see due to their elevated face height. They are designed to be hammered into hard ground using the frame as a post driver. The frame is also designed to make it easy to remove the stake from the ground by using the frame as a reverse post driver. Thus, no additional tools are required. Although, the Ninja Sign is great for outdoor use, it is not limited to outdoor applications. 
       BRIEF SUMMARY OF THE INVENTION 
       [0008]    The disclosed invention pertains to a transportable sign that is compact for storage, and easy to use. There are many variations of the design and this brief summary of the invention is not intended to limit the scope of the invention in any way, as it is merely exemplary. 
         [0009]    A Ninja Sign comprising a rigid, spanning member approximately the length of a sign face in height (length referring to vertical length of the face). At one end of the spanning member is a housing assembly, and at the other end there is a mounting device for mounting the spanning member to a hard floor in a vertical position (both the housing assembly and the mounting device are described below, along with other components of the Ninja Sign). A spanning member can be hollow, thus being able to accommodate a stake that can be extended out the mounting device end of the spanning member. Two flanges, one on the inside of the spanning member near the mounting device, and the other on the stake near the top, can prevent the stake from being completely removed from the spanning member. Thus, the stake can be partially extended out the spanning member and pinned such that the extended portion of the stake is the desired length for inserting into the ground. The pin prevents the stake from going all the way back inside the spanning member. 
         [0010]    The Ninja Sign would ideally have two arms, each comprising a first arm component, and a second arm component (an arm can be just a first arm component). The second arm components can be approx. the length of the spanning member, and in a closed position they can appear on opposite sides of the spanning member while extending from the mounting device to the housing assembly. A first arm component connects a second arm component to the housing assembly; it can do so such that each second arm component can rotate relative to its respective first arm component, and each first arm component can rotate about a point on/in the housing assembly. The pivot point between a first arm component and a second arm component will partly determine the sign face height and size as explained below: for conceptual purposes it is safe to make this point slightly lower than the center of a second arm component. The second arm components can be connected at their respective ends to the housing assembly and mounting device to secure them in a closed position. 
         [0011]    The housing assembly holds the arms to the spanning member such that the arms and spanning member can lie within a small variation of a common plane in the open, and/or closed position(s). The housing assembly can be part of the spanning member, or it can be a separate component. The arms, housing assembly, and mounting device should each be symmetrical about a line parallel to, and through the center of the spanning member in a closed and open position. They should also be minimal in size, and compact to reduce storage space. 
         [0012]    A mechanical system can connect the first arm components of the arms such that when one first arm component rotates relative to the spanning member, the other one rotates an equal amount in the opposite direction. Thus the two first arm components maintain a common angle relative to the spanning member. This mechanical system can consist of a set of congruent, interlocking gears in/on the housing assembly; each gear attached to a first arm component and centered at the point of rotation of each respectively. Thus when one first arm component rotates, the interlocking gears cause the other first arm component to rotate an equal amount in the opposite direction. 
         [0013]    The mounting device can be used to mount the spanning member to a hard surface in a vertical position. In many outdoor applications, where the Ninja Sign cannot be mounted to a hard surface, the stake can be extended from the spanning member and pinned. The frame (comprising the spanning member, and arms) can then be used as a manual post driver for inserting the stake into the ground. 
         [0014]    After the spanning member is firmly mounted vertically, the ends of the second arm components can be disconnected from the housing assembly and mounting device thus allowing the arms to rotate about their respective points in the housing assembly. The first arm components can be rotated to a horizontal position and temporarily secured in place from below (allowing them to rotate up but not down), while the two second arm components are able to move independent of each other until the face(s) are attached. Rectangular sign face(s) can then be mounted on the frame by attaching each top corner of each face to one end of a different second arm component (housing assembly end). One bottom corner (common side) of each face can then be attached to the mounting device end of its respective second arm component, thus we have 3 of the 4 corners of each face mounted on the arms. The 4th corner of each face can be attached to the remaining end of the second arm component by rotating each second arm component to as vertical of a position as the face will allow. Holding the remaining end of the second arm component and pushing it towards the spanning member will cause the first arm components to rotate, while bringing the mounting device ends of the second arm components closer together, and thus allowing you to attach the 4th corner of the face(s) to the frame. After connecting the 4th corner of a face, and letting go, the weight of the arms pull the face(s) taunt. 
         [0015]    To remove the Ninja Sign, press one end (mounting device end) of a second arm component towards the housing assembly and disconnect the face(s) at that end. Lower the arms by allowing respective end of the second arm component to slowly move away from the spanning member which will cause the arms to lower. Disconnect the face(s) from the frame and secure the respective ends of the second arm components to the housing assembly and mounting device. Disconnect the mounting device from the floor if applicable. If applicable, use the frame as a reverse post driver to hammer the stake out of the ground. Then remove the stake pin and slide the stake back inside the spanning member. Thus the ( ) is in the closed position. 
         [0016]    Some of the many advantages of the invention over prior art can include, but are not limited to: not needing any tools to set up the Ninja Sign, reducing storage space, making it easier to reuse and transport signs, improved elevation height of the face(s), and the ability to put a sign up that is taller than you physically are.

         [0056]      FIG. 1  is an isometric view illustrating a Ninja Sign in a horizontal and closed position comprising: a spanning member  1  coupled to a first and second arm: each arm comprised of a first arm component  2 , and a second arm component  3 , wherein each component lies within a region on or between a housing assembly and a mounting device, and each arm lies adjacent to a spanning member with a limited arm motion in a closed position. Two side plates  5  symmetrically attached on opposite sides of one end of a spanning member  1  help form a housing assembly. Two side plates  9  symmetrically attached on opposite sides of the other end of a spanning member  1  help form a mounting device in the form of a brace. A second arm component  3  can pivot relative to its respective first arm component  2  about a pin through hole  4 . Holes  7  in a second arm component  3  align with their respective holes  6  in a side plate  5 . Likewise, holes  11  in a second arm component  3  align with their respective holes  10  in a side plate  9 . Holes  6 ,  7 ,  10 , and  11  allow the second arm components  3  to be securely attached via pins to a housing assembly and brace. A pin through a housing assembly inserted through hole  12  penetrates a gear  8 , a first arm component  2 , and another gear  8 , thus connecting an arm and two gears to a housing assembly. A spanning member accommodating a stake as shown in  FIG. 2 . 
         [0057]      FIG. 2  depicts that which is shown in  FIG. 1  with a stake  13  partially extended out the brace end of a spanning member  1 . 
         [0058]      FIG. 3  shows that which is depicted in  FIG. 2  but with a stake  13  pinned below a spanning member  1  to allow only part of a stake  13  to be reinserted back into a spanning member  1 . 
         [0059]      FIG. 4  is a front view illustrating that which is shown in  FIG. 3  with a Ninja Sign in hammering position A having a spanning member being vertical to the ground. The arms are closed, and the bottom of a stake  13  is extended out the brace end of a spanning member  1  and pinned with the brace resting on the pin. The mark near the bottom of a stake  13  is at ground surface level. 
         [0060]      FIG. 5  illustrates hammering position B: the same as hammering position A but with the frame elevated thus extending the stake  13  out of the spanning member  1  further. 
         [0061]      FIG. 6  illustrates that which is depicted in  FIG. 4  but with the bottom of a stake  13  partially below ground surface level. 
         [0062]      FIG. 7  illustrates that which is depicted in  FIG. 5  but with the bottom of a stake  13  partially below ground surface level. 
         [0063]      FIG. 8  illustrates that which is depicted in  FIG. 6  but with the bottom of a stake  13  further below ground surface level. 
         [0064]      FIG. 9  illustrates that which is depicted in  FIG. 7  but with the bottom of a stake  13  further below ground surface level. 
         [0065]      FIG. 10  illustrates that which is depicted in  FIG. 8  but with a stake  13  properly inserted into the ground. 
         [0066]      FIG. 11  is an isometric view of a Ninja Sign with first arm components  2  and second arm components  3  in a closed position. A spanning member being vertical. 
         [0067]      FIG. 12  is an isometric view of the back of a Ninja Sign having first arm components  2  and second arm components  3  partially open, having pivoted about the center of hole  12  respectively. 
         [0068]      FIG. 13  is a rear isometric view of a Ninja Sign having first arm components  2  and second arm components  3  partially open, having pivoted about the center of hole  12  respectively. The first arm components  2  being horizontal. 
         [0069]      FIG. 14  shows a rear isometric view of a Ninja Sign with first arm components  2  being horizontal, and second arm components  3  being partially rotated into a vertical position. Second arm components pivotally coupled near the middle to first arm components. “Near the middle” meaning not at the ends. Arm components rotate relatively parallel to a common plane. 
         [0070]      FIG. 15  shows a front view of a Ninja Sign with first arm components  2  being horizontal, with one second arm component  3  being vertical, and the other second arm component  3  being partially rotated into vertical position. First arm components pivot at a relatively common elevation on a housing assembly. 
         [0071]      FIG. 16  shows that which is depicted in  FIG. 15 , but with a face partially attached to a Ninja Sign at three of the four corners. A pin through each attached corner penetrating through holes  7  and  11  respectively hold the face on a second arm component  3 . While holding the unattached end of the second arm component  3 , an applied force directed towards the housing assembly can move the arms into fully open position as shown in  FIGS. 17 and 18 . A face  14  being roll able/foldable. 
         [0072]      FIG. 17  is a front view of a Ninja Sign in a fully open position having only one face attached. 
         [0073]      FIG. 18  is a rear view of a Ninja Sign in a fully open position having only one face attached. A wind directed towards the face causes the first arm components to rotate closer together thus reducing the cross sectional area of the face to relieve stress on the frame. See  FIG. 21 . 
         [0074]      FIG. 19  is a rear isometric view of a fully open Ninja Sign having two faces, one on each side attached to the second arm components  3 . 
         [0075]      FIG. 20  is a front view of a rectangular face  14  having a grommet  15  in each corner for attaching to a second arm component via a pin. 
         [0076]      FIG. 21  is a front elevated view of a housing assembly with two first arm components  2 , and a mechanical system. First arm components  2  each insert into the housing assembly between two side plates  5 , and two gears  8 . Pins through holes  12  respectively penetrate both side plates  5 , both gears respectively, and a first arm component  2 , thus, securing the first arm components  2 , and gears  8  to the housing assembly. Gears  8  centered at the same hole  12  are additionally connected to their respective first arm components  2 , thus, when one first arm component  2  rotates relative to the spanning member  1 , the interlocking gears  8  force the other first arm component  2  to rotate the same amount in the opposite direction. Gears  8  in a housing assembly assure that first arm components  2  stay symmetrical about a vertical line through a housing assembly, thus holding the face(s)  14  symmetrical as well. 
         [0077]      FIG. 22  is a bottom elevated view showing a brace, and a top portion of a stake  13 . A brace comprising two side plates  9 , and two spacers  16  each having a hole  17  for mounting the Ninja Sign to a solid surface. Flange  19  in a spanning member  1 , and flange  18  on the top portion of a stake  13 , prevent a stake  13  from being completely removed out the brace end of a spanning member  1  after being inserted in the housing assembly end. 
         [0078]      FIG. 23  is an isometric view of a Ninja Sign comprising third arm components  20  such that second arm components  3  pivot at the ends of first arm components  2 , and third arm components  20  pivot at the ends of second arm components  3 ; third arm components  20  couple at the top in an open position forming a face frame for holding a face  14 . 
         [0079]      FIG. 24  is an isometric view of the Ninja Sign from  FIG. 23  wherein the arms are in a partially closed position. The third arm components  20  being adjacent to their respective second arm components  3 . Arm components  20 , and  3  then fold inwards until resting on first arm components  2  respectively. Each arm then rotates downwards until all arm components  2 ,  3 ,  20  are parallel to spanning member  1 . 
         [0080]      FIG. 25-27  are isometric views of a Ninja Sign comprising: a first arm component  2  that rotates past horizontal, over the top of a spanning member  1  into an open position as shown in  FIG. 26 , and is held up by restricting the motion of a respective joint thus giving the joint limited rotation; and a second first arm component  2  that rotates in an opposite direction, as shown in  FIG. 27 . 
         [0081]      FIG. 28  is a front view of a Ninja Sign comprising a spanning member  1  having 4 first arm components  2  attached for holding a face  14 . 
       Means of Manufacturing: 
       [0082]    A spanning member  1  can be constructed out of steel square tubing cut to the proper length. A housing assembly can be constructed by utilizing a set of small side plates  5 ; each side plate having four holes  6  and  12  can be cut out with a laser and positioned at opposite sides of one end of the spanning member  1  such that that they extend past its end. A jig can be used to properly align the holes  6  and  12  of the side plates such that a line through the center of a hole  12  in one side plate  5 , and passing through the center of its respective hole  12  in the other side plate  5 , is perpendicular to the spanning member  1 . The side plates  5  can then be welded into position. 
         [0083]    Another set of small side plates  9 , with two holes  10  each, can be constructed and attached to the other end of the spanning member  1  in a similar fashion. In the space between these two plates  9 , there can be a spacer  16  on each side of the spanning member  1  for bolting the frame to a floor. Such a spacer  16  can be constructed by shearing sections of stock steel and punching a hole  17  near the center. The spacers  16  can then be welded between the two plates  9  thus forming a brace that can bolt to a hard surface to hold the spanning member  1  vertical. Small strips of thin steel can be welded inside the spanning member  1  near the brace thus creating a flange  19  as shown in  FIG. 22 . 
         [0084]    A stake  13  can be partly constructed out of a steel tube with small strips of steel welded all the way around one end to form a flange  18  as shown in  FIG. 22 . Sections of solid round rod can be cut at angles and inserted part way into the other end of the stake  13  and welded to create a sharpened point. A pin hole can be drilled in the stake  13  before inserting it into the spanning member  1  via the housing assembly end. 
         [0085]    A first arm component  2  can be constructed out of steel square tubing with holes drilled at each end. An end of the first arm component  2  attaching to a housing assembly  1  can be slightly bent allowing it to curve further over the top of the spanning member  1  as shown in  FIG. 21 . A second arm component  3  can be constructed by taking two adjacent sections of steel square tubing and offsetting them a distance of at least the thickness of the first arm component  2 . A steel offset can be welded between the two sections at the top and bottom of the second arm component  3  thus preserving this shape. The relationship between the arm components should be such that the second arm components  3  are slightly less wide than the spanning member  1 , and a first arm component  2  fits between the two square tubes of the second arm component  3  with enough room for a washer on each side. A jig can be used to drill three holes in each second arm component  3  in the proper positions: each hole must go through both square tubes of each second arm component  3 : one hole is drilled at each end, and a third hole is drilled at the pivot point between the first arm component  2  and the second arm component  3  creating hole  4 . 
         [0086]    Each second arm component  3  can then be positioned such that one end is positioned between the two plates  5  of a housing assembly, and the other end is positioned between the two plates  9  of a brace. A pin can then be inserted through the outer most holes  6  of a housing assembly and a second arm component  3 , along with a pin through a brace and the same second arm component  3 , thus securing the second arm component  3  to a spanning member  1  at both ends. Likewise, the other second arm component  3  can then be secured to the spanning member  1  as well. 
         [0087]    A first arm component  2  can now be attached to a second arm component  3  via a pin through the hole at one end of the first arm component  2 , and the remaining hole of the second arm component  3 . A first arm component  2  should be positioned such that it lies between the two square tubes of a second arm component  3  and is separated from the second arm component  3  on each side by a washer. A steel gear  8  cut with a laser can then be placed on each side of a first arm component  2 , centered with the hole. The gears  8 , and a first arm component  2  can then be pinned through the inner holes  12 , between the two side plates  5  of the housing assembly. Washers may be needed to take up any extra space between the gears  8  and side plates  5 . The other first arm component  2  can then be attached in a similar fashion such that the set of gears  8  through one pin are interlocking on the set of gears  8  on the other pin. 
         [0088]    Once the arm components are attached and in the closed position, the gears  8  can be welded to their respective first arm components  2  thus forcing one first arm component  2  to rotate relative to the spanning member  1  when the other first arm component  2  does. The pins securing the first arm component  2  to the housing assembly, along with the pins connecting the first arm component  2  and the second arm component  3  can now be welded in place to prevent them from falling out. Everything can then be cleaned for painting. 
         [0089]    A sign face  14  can be constructed of a banner material with printing on one side. For additional strength, Power Tape can be applied to the back side of a face  14 . Four grommets  15 ; one at each corner can be used to hold the face(s)  14  to an open frame. The same four pins used to hold the arms in a closed position can be used to hold the face(s)  14  to the frame by inserting a pin through a grommet  15  in one face  14 , then back into the hole in the second arm component  3 , and then through a grommet  15  in the other face  14 . 
       Means of Erecting: 
       [0090]    A Ninja Sign can be mounted to a solid surface by placing a bolt through the top end of each hole  17  and threading it through a solid surface to secure the Ninja Sign in a vertical position. 
         [0091]    A Ninja Sign can be mounted in the ground by extending stake  13  out the brace end of spanning member  1 . A pin through stake  13  is then inserted to prevent stake  13  from sliding all the way back inside spanning member  1 , as shown in  FIG. 3 . With the arms in a closed position, a Ninja Sign can be lifted vertical into hammering position A as shown in  FIG. 4 . By holding the arms of a Ninja Sign, one in each hand, a Ninja Sign frame can then be elevated into hammering position B as shown in  FIG. 5 . A Ninja Sign frame can then be used as a post driver by slamming it down vertically onto a pin through stake  13 ; thus, inserting stake  13  partially into the ground as shown in  FIG. 6 . Repeating this concept by moving a Ninja Sign frame into a position shown in  FIG. 7  and slamming it into a position shown in  FIG. 8  inserts a stake  13  further into the ground. This process can be repeated until stake  13  is inserted sufficiently into the ground. In cases where stake  13  doesn&#39;t need to be inserted into the ground to where its pin is at ground level, the pin can be removed allowing the frame to rest on the ground. 
         [0092]    After securing a Ninja Sign frame in a vertical position (See  FIG. 11 ), the second arm components  3  can be disconnected from the housing assembly and brace. This can be done by removing the pins through holes  6  and  7 , and the pins through holes  10  and  11  respectively. The first arm components  2  can then be rotated until horizontal as shown in  FIG. 13 . A pin can then be reinserted into one hole  6  such that a first arm component  2  can rest on this pin thus holding the first arm components  2  horizontal. Second arm components  3  can then be rotated into position for attaching a face, as shown in  FIG. 15 . 
         [0093]    A face  14  can be attached to the arms of a Ninja Sign by inserting a pin through a grommet  15  in the face  14 , and then inserting it into hole  7  in a second arm component  3 . Repeat this with hole  7  of the other second arm components  3 , and hole  11  of one second arm component  3  as shown in  FIG. 16 . From the position shown in  FIG. 16 , apply a force from the unattached end of the second arm component  3  that is directed towards the housing assembly; this will cause the arms to elevate, bringing the remaining corner of the face  14 , and the remaining hole  11  of a arm, in closer proximity of each other. Remove the pin from hole  6  in the housing assembly (the one that was holding the first arm components  2  horizontal), and insert it through the remaining grommet  15  in the face  14 , and the remaining hole  11 . 
         [0094]    Thus we have one face  14  attached to a Ninja Sign frame. If a second face  14  is desirable, start at the position shown in  FIG. 16 . Attach a second face  14  by inserting the second face  14  onto the end of the pins that are holding the first face  14  (each pin will be inserted through the first face  14 , then through the second arm component  3 , and then through the second face  14 ). Then proceed as instructed above and connect the remaining corner of the second face  14  onto the final pin. 
       Means of Removing: 
       [0095]    While holding one of the second arm components  3  near hole  11 , apply a small force towards the housing assembly; such force should be just enough to remove pressure on adjacent corner of face  14 . Remove adjacent pin, thus freeing that corner of the face(s)  14 . Proceed to allow the second arm components  3  to slowly lower by reducing the amount of force applied towards the housing assembly. Once the arms are down, proceed to remove the pins that are securing the face(s)  14  to the arms. Roll the face(s)  14  around a small shipping tube to preserve shape and prevent unnecessary wrinkles. Pin the arms in closed position by reinserting the pins through holes  6  and  7 , and  10  and  11  respectively. 
         [0096]    If the Ninja Sign was mounted to a solid surface, simply remove the bolts through the brace to remove the sign. If the Ninja Sign was mounted using stake  13 , use the frame as a reverse post driver to remove stake  13 . This can be done by ramming the frame up until it is stopped by flange  18  of stake  13  hitting flange  19  in the spanning member  1  (see  FIG. 22 ). Thus, starting from the position shown in  FIG. 10 , proceed to ram the frame upwards into the position shown in  FIG. 9 . Slowly lower the frame into the position shown in  FIG. 8 , and proceed to ram the frame up into the position shown in  FIG. 7 . Repeat this process until stake  13  is removed from the ground. Lay the Ninja Sign on the ground, remove the pin from stake  13 , and then slide stake  13  back inside spanning member  1 . 
       Distinguishing Between Prior Art: 
       [0097]    There are a wide variety of sign designs considered prior art; none of them having means of inserting a stake into, and removing a stake from, the ground. Additionally, none of them collapse into a compact position that is convenient to fit in a vehicle without having a disconnected arm component that can get lost. It is desirable to provide a commercial or residential size sign that collapses to fit in a vehicle, doesn&#39;t require any tools, holds against significant wind speeds, and is simple to use, in the form of a Ninja Sign.
