     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved swing arm chair apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the swing arm chair apparatus 10 of the instant invention essentially comprises a chair structure having a chair seat 11, with a chair back support 12 extending upwardly relative to the chair seat, and the chair including a base portion having a first side wall 13 spaced from a second side wall 14, and a front wall 15. A first arm extends from the back support 12 to the front wall 15 along the first side wall 13. Similarly, a second arm 17 extends along the second side wall 14 from the back support 12 to the front wall 15. 
     The first side wall (see FIGS. 5 and 6 for example) includes a first side wall top wall 18 oriented at an oblique angle relative to the first side wall, and extends from the first side wall to the chair seat coextensive with the first side wall. A top wall lock bore 19 is orthogonally directed into the top wall 19 in adjacency to the front wall 15 and the chair seat 11. 
     The arm is formed with a first arm bottom wall 20, with a first arm bottom wall axle 21 orthogonally oriented to the first bottom wall 20 and directed into the first side wall top wall 18. The first arm bottom wall axle 21 is received through an axle bore 22 directed through the top wall 18 in a spaced relationship relative to the lock bore 19 parallel to the lock bore, with the first arm bottom wall axle 21 oriented in a parallel relationship relative to the lock bore 19 and positioned in adjacency relative to a rear distal end of the first arm bottom wall 20. 
     Oriented adjacent a forward end of the first arm bottom wall 20 is a cylindrical latch bolt 23 having a latch bolt axis 23a. A latch bolt arm 24 orthogonally oriented relative to the axis 23a is integrally and medially mounted relative to the latch bolt 23. A latch bolt rod 25 has an upper distal end indicated as a bifurcated first end 26 pivotally mounted to the latch bolt arm 24 to permit pivotal relationship of the latch bolt arm 24 relative to the latch bolt rod 25, whereupon pivoting of the latch bolt 23 provides for selective lifting of the latch bolt rod 25 relative to the top wall lock bore 19 to permit displacement of the swing arm or first arm 16 to the second position, as indicated in FIG. 5. To ease such rotation of the latch bolt 23, a latch bolt lever 27 orthogonally mounted and integrally secured to the latch bolt 23 at a free end thereof exteriorly of the first arm 16 between the first arm 16 and the second arm 17 is mounted to permit ease of lifting of the latch bolt rod 25, in a manner as indicated in FIG. 6 for example. 
     A plurality of latch bolt saddles 28 extend about the latch bolt 23 and are secured to a top surface of the top wall 18, with the latch bolt arm 24 as indicated oriented between the latch bolt saddles 28. 
     FIG. 7 indicates the use of a somewhat modified top wall 18 having a top wall recess 29 extending medially of the top wall, having a recess floor 30 positioned below a top surface of the wall a predetermined height. A floor recess cavity 31 is directed into the recess floor 30 for storage of various components such as pencils, pens, and the like. A desk plate 32 having a predetermined thickness equal to the predetermined height is pivotally mounted about a desk plate axle 33, with the desk plate axle 33 orthogonally directed into the recess floor 30 in a parallel relationship relative to the top wall lock bore 19. In this manner, access to the desk plate 32 is provided for use as a desk structure, wherein various pencils and the like may be stored within the recess floor cavity 31 for use with the desk plate 32. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
