Abstract:
A way to convert a camera tripod into an artist easel. The easel consists of a one or two arm design employing a built-in adapter, or connecting device in the center of the arm(s) of the attaching easel whereby the easel arm attaches directly to the mounting device of the tripod by way of the connecting device, allowing the tripod features to be extended to the easel. Attributes such as the tilting, raising, and rotating features of the tripod are then incorporated and translated as new easel functions.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of provisional application Ser. No. 62/195,550, filed Jul. 22, 2015 by the present inventor. 
     
    
     BACKGROUND 
     Field 
       [0002]    This application relates to an easel, specifically artist and display easels. 
       Background of the Invention 
       [0003]    U.S. Pat. No. 5,791,623—granted to Michael C. Louridas on Aug. 11, 1998 performs the same function of combining, adapting, and connecting an easel to a camera tripod as this embodiment. I found that Louridas&#39; solution was too complicated. This embodiment is much simpler and eliminates the need for a middle carriage bracket to interface between the camera tripod and easel arm. 
       SUMMARY OF THE EMBODIMENT 
       [0004]    This embodiment features an easel arm, or arms, that attaches directly to a camera tripod-like mounting mechanism using an embedded connecting device and optional drill hole for a mount nipple(s) or guide. This empowers the user to cost and space savings, along with adding the tripod-like features to the easel. The easel allows for the work piece to be secured to the tripod, and be manipulated for height adjustment—to tilt, be rotated, and/or swivel according to the capabilities of the tripod. Now the easel performs more than just a resting place for the work piece. The marriage of the easel and tripod functions allow for a new hybrid unit to be created. This embodiment now affords more utility and value to the owner. 
         [0005]    The advantage of this embodiment over prior art is the simplicity of directly attaching to the camera tripod mount and forgoing the perceived need for an intermediary carriage bracket interface as taught by Louridas—U.S. Pat. No. 5,791,623. There is a significant improvement in this embodiment that saves on the cost to manufacture the parts, and thus lowers the price of the product, and also eliminates having extra parts that could break down.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0038]    Most every artist and presenter requires an easel to display and secure their workpieces. Many visual artists also engage in both painting and photography. Thus, the need for a camera tripod and easel. With this embodiment, the artist or presenter can simply and quickly convert an ordinary camera tripod using a standard mounting device into an artist easel with the combined attributes of both devices. 
         [0039]    The versatility of the camera tripod transfers over to the easel attachment. If the tripod has adjustable legs, the adapted easel then supports varying height adjustments. Likewise, if the tripod head swivels, rotates, or tilts—so will the easel. 
         [0040]    This embodiment is a simple and direct solution to solve the problem of uniting two formerly different and segregated pieces of equipment. The cost is reduced along with saving space, and the simple solution eliminates extra unneeded parts that could break down. Consolidating redundant items saves money and space which could now be both put to more productive uses 
         [0041]    This embodiment is designed to quickly interface with a camera tripod mount to convert the tripod into an easel with all the attributes included in the tripod. Depending on the tripod, these attributes include but are not limited to height adjustment, swiveling features, rotating features, and angle face variation. 
         [0042]    This embodiment is made of wood, but may be made from other materials such as metal, plastic, or other compounds, but are not limited to these. The connecting device in this model shown uses a threaded insert used to connect the easel arm to the camera tripod. The connecting device could be an insert nut, or a specially made threaded insert to be pressed, screwed in, or otherwise secured into the center of the easel arm. The connecting device could be made to be part of the arm itself. The connecting device is what marries the easel arm to the camera tripod. The connecting device should accommodate a ¼ inch machine screw for present camera tripod mount models, but this can vary to accommodate any type of past, present, or future camera tripod mount, or other support mechanism. This embodiment is designed to attach to an existing camera tripod, but is not limited to such. A specific and distinct tripod made to be used for both a camera and the easel arm, could also be created. 
       Detailed Description of the Specific Embodiment 
     Description of First Embodiment 
     FIG.  1 A- 1 E—Single Easel Arm w/ Threaded Insert 
       [0043]    The embodiment presented here in  FIG. 1A  is the easel arm ( 1 ) with an insert nut, or a threaded insert ( 2 ) as the connecting device mounted securely into the center of the arm ( 1 ). The single arm ( FIG. 1A ) holds a work piece securely on two sides by way of the sliding bar clamps ( 8 ). However manufactured, the connecting device is secured into the middle and center of the easel arm ( 1 ). 
         [0044]      FIG. 1B  is a side view of the easel arm ( 1 ). A hole ( 3 ) is drilled in the center of the arm ( 1 ) for the connecting device (here an insert nut ( 2 )), to be inserted and secured into the arm ( 1 ). Another small drill hole ( 4 ) is made in the arm for the nipple guide ( 5 ) on the mount ( 7 ) to be inserted when attaching the arm ( 1 ) to the mount ( 7 ). The connecting device ( 2 ) here as an insert nut ( 2 ) has inner threads (¼ inch in this case) for the screw ( 6 ) on the mount ( 7 ) to screw into and be secured. 
         [0045]      FIG. 1C  teaches how the mount ( 7 ) is guided into the easel arm ( 1 ).  FIG. 1D  shows the arm ( 1 ) mated to the mount ( 7 ) by way of the connecting device ( 2 ) and nipple guide hole ( 4 ). 
         [0046]      FIG. 2A  is a side view of the easel arm ( 1 ) attached to the mount ( 7 ) and here mated to a camera tripod ( 13 ).  FIG. 2B  is a side view of the easel arm ( 1 ) attached to the tripod ( 13 ) and with the sliding bar clamps ( 8 ) fastened to the arm ( 1 ).  FIG. 2C  is an example of a mount employing a rotational ball ( 14 ). This design allows for the mount to swivel, tilt, and rotate. 
         [0047]      FIG. 3A  illustrates a canvas ( 15 ) being mounted on the tripod ( 13 ) through the attached easel arm ( 1 ) and held in place with the sliding bar clamps ( 8 ).  FIG. 3B  illustrates how the canvas can be manipulated and positioned according to the attributes afforded in the tripod design.  FIG. 3C  illustrates the canvas ( 15 ) being manipulated into a horizontal position (used by many watercolorists).  FIG. 3D  shows how the swivel or rotational feature of the tripod mounting head mechanism rotates the canvas 360 degrees in either direction while in a horizontal (not limited to such) position. 
       Operation of First Embodiment 
     FIGS.  1 A- 1 D, &amp;  2 A- 2 C, &amp;  3 A- 3 D—Single Easel Arm with Threaded Insert 
       [0048]    The easel arm ( 1 ) attaches and is mated and secured to the camera mount (or other similar mating mechanism) ( 7 ) by screwing the mounting screw ( 6 ) into the inner threads of the threaded insert ( 2 ) in the easel arm ( 1 ). If there is a stabilizing nipple(s) ( 5 ) on the camera mount ( 7 ), this is lined up and inserted into the hole ( 4 ) on the easel arm ( 1 ) to keep the mounted easel more secure. 
         [0049]    The sliding bar clamps pictured here ( 8 ) slide on or over the easel arms ( 1 ) and are secured to the arm ( 1 ) with the thumb screws ( 12 ). The canvas ( 15 ) is secured onto the easel ( 1 ) by being sandwiched ( FIG. 3A ) between the sliding bar clamps ( 8 ). The secured canvas ( 15 ) can then be maneuvered and positioned being limited to the functions afforded by the camera tripod ( 13 ) to benefit the user. 
       Description of the Second Embodiment 
     FIG.  1 E—Double Easel Arm w/ Threaded Insert 
       [0050]    In  FIG. 1E  we have a double easel arm ( 1  and  9 ) attached together in a crisscrossed fashion. Again, the connecting device ( 2 ) here is an insert nut ( 2 ) (with inner ¼ inch threads) inserted and secured into the center of the central arm ( 1 ). The central arm ( 1 ) connects to the mount ( 7 ) in the same fashion as the single arm embodiment. The two arm embodiment adds extra support for the canvas by gripping the work piece on all four sides. 
       Operation of Second Embodiment 
     FIGS.  1 E—Double Easel Arm with Threaded Insert 
       [0051]    The mounting mechanism ( 7 ) is screwed into the connecting device ( 2 ) in the easel arm ( 1 ) and re-attached to the tripod ( 13 ). The canvas ( 15 ) is now secured by the sliding bar clamps ( 8 ) on all four sides instead of just two in the single arm embodiment. 
       Description of Alternative Embodiments 
     FIGS.  4 A &amp;  4 B—Wall Mount and Telescoping Arm 
       [0052]      FIG. 4A  is an example of how the easel arm ( 1 ) can be attached to a mounting mechanism ( 7 ) and camera mount head ( 14 ) which is also attached to a wall mount ( 18 ) instead of a camera tripod ( 13 ) and allows the artist or presenter the ability to rotate and tilt his work piece while being mounted on a wall. This saves space in the artist&#39;s studio, or gives a presenter an option for displays. The wall mount could be stationary or be equipped with a sliding mechanism to adjust the height. 
         [0053]      FIG. 4B  shows how the easel arm ( 1 ) with the embedded connecting device ( 2 ) can be attached directly to a telescoping arm ( 20 ) (however designed) that is attached to a wall mount ( 18 ), enabling the canvas to be adjusted for distance and height, and even with rotating features found on the head mount ( 14 ). This is an example of what can be done with a telescoping arm ( 20 ) with this direct attach easel arm ( 1 ) and connecting device ( 2 ), but is not limited to this design and scenario. 
       Operation of Alternative Embodiments 
     FIGS.  4 A &amp;  4 B—Wall Mount and Telescoping Arm 
       [0054]    The artist or presenter can directly attach the easel arm ( 1 ) to the mounting mechanism ( 7 ) and this is held in place with the nipple ( 5 ) on the mount ( 7 ) pushed into the drill hole ( 4 ) on the easel arm ( 1 ). The detachable head mount ( 14 ) could be used to interface with the wall mount ( 18 ) and the easel arm ( 1 ), or attach directly to the wall mount ( 14 ). Existing tripod head mounts ( 14 ) can be used, or specially designed similar mounting mechanisms ( 7 ) for just this purpose can be used to join the embedded connecting device ( 2 ) in the easel arm ( 1 ) with the mounting device ( 7 ) and easel arm ( 1 ). 
         [0055]    The telescoping arm ( 20 ), gives the user the added ability to adjust the distance of the work piece from himself to a more comfortable distance. The easel arm ( 1 ) attaches to the mounting mechanism ( 7 ) on the telescoping arm ( 20 ) and is pulled out or pushed in, or otherwise maneuvered depending on the design of the telescoping arm ( 20 ). The artist can then sit and adjust the distance of the work piece, or maneuver the workpiece to the desired position. A stationary or sliding wall mount ( 18 ) is attached to the wall ( 19 ). The telescoping arm ( 20 ) is attached to the wall mount, and in this design the tripod head ( 14 ) connects to the other end of the arm ( 20 ) which then connects to the easel arm ( 1 ). The tripod head ( 14 ) with rotational features will allow the work piece to be rotated and tilted along with adjusting the distance and height. All these options give the artist the added ability, ease, and comfort to focus more on his creation. 
       Construction of the Embodiments 
       [0056]    The construction of these embodiments are simple. The easel arm ( 1 ) in this case is made of ½ inch thick wood (poplar or oak) with a width of approximately 2 inches and 24″ long. 
         [0000]    These dimensions and materials can be varied using the same basic design employed here. In the center (both length and width) of the easel arm ( 1 ) a hole is drilled ( 3 ) (about ⅜-inch-wide in this case) through the center arm(s) ( 1 ) for the threaded insert connecting device ( 2 ) to fit into, and be secured. This threaded insert could be an insert nut or some other threaded insert that is secured into the hole ( 3 ) of the easel arm ( 1 ). The threaded insert should be compatible with the present ¼ inch machine screw threads found in most camera mounts. 
         [0057]    In the two arm model ( 1 E), the central arm ( 1 ) is notched out on both sides in the middle so side arms ( 9 ) can be fitted and secured into the central arm ( 1 ). In this case with glue. 
       CONCLUSION, RAMIFICATION, AND SCOPE 
       [0058]    The reader will see that at least one embodiment of the easel arm utilizes the already designed and manufactured aspects of preexisting camera tripods, and adds the extra utility of a clamping easel to provide rotational, tilting, and height adjustments normally not present in the standard easel alone. 
         [0059]    The direct attachment feature of this embodiment eliminates the need for an intermediate carriage bracket to interface between the easel arm and the camera tripod mounting device. 
         [0060]    The use of readily obtainable materials and hardware is desirable for easy replacement and repair of the embodiment. However, the envisioned embodiments are not limited to preexisting parts. 
         [0061]    The easel arm and any of the parts can be made of any suitable material—plastic, wood, metal, or composite material, but not limited to such, and be constructed in any size, shape, or color. 
         [0062]    This embodiment is envisioned and designed for use by an artist or a presenter to provide extra functionality in their workspace. However, other unintended uses and variations could also be made of this embodiment using this general design. For instance, the easel assembly could be different (using a different mounting mechanism); and/or using an additional sliding or stationary wall mount or a telescoping arm attached to a wall mount ( 18 ) that allows for a tripod head ( 14 ) to be connected to the other end of the extended arm—instead of a tripod, but not limited to these other possibilities. The easel arm ( 1 ) would still directly attach to the different mounting mechanisms ( 7 ) and heads ( 14 ). 
         [0063]    This embodiment could also be motorized so that the easel assembly attaches to a different mount ( 7 ) other than the camera tripod mounts and can be mechanically and remotely adjusted. A specially designed tripod or similar structure could be built specifically for easel use with the necessary specifications for that work load, and may also contain camera capabilities for extended utility—all using this direct-attach design.
