CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to and the benefit of U.S. Provisional Application Ser. No. 62/387,536, entitled “ARTICULATING, SELF RETAINED ON-WALL BRACKET MOUNTING SYSTEM” filed on Dec. 23, 2015, the entire contents of which is incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    This invention provides a constrained, 2-Axis, articulating, self-retained and position maintaining, on-wall bracket mounting system. Specifically, this invention enables the mounting of diverse shaped and various sized devices on walls such as the mounting of loudspeaker systems. 
         [0004]    2. Related Art 
         [0005]    Tens of millions of on-wall loudspeaker systems have been installed the world over and all of them present their installers a series of installation challenges that fall into two broad categories. The first is aligning it with the environment into which it is being installed and the second is the method by which it is secured or retained into the preferred position. While many of these systems feature only a single axis mounting bracket system, thereby simplifying the alignment issue, they still mostly require the installer to manually insert and activate some kind of threaded fastening system and then to make a “best guess” as to how one system aligns or duplicates the positioning of a second, third or more systems. The alignment/retention issue becomes even more challenging when the widely employed “ball and socket” system (Omni-Mount® type) is used as it provides the installer with few if any limitations to its potential orientation. While some might view this as an inherent advantage, in reality if the installation requires at least a modicum of consistent symmetry between the various loudspeakers and their environment, then the ball and socket method becomes substantially more bothersome and expensive to install. And all of the legacy ball and socket systems require the installer to manually install and activate the aforementioned threaded fastening system, usually while perched precariously high up a ladder, holding the loudspeaker system in the desire position with one hand and a screwdriver in the other hand, all while trying to insert the screwdriver into the tensioning fastener&#39;s drive head which in invariably located in some dark, awkward, difficult to find location. 
         [0006]    The invention disclosed circumvents the aforementioned difficulties. It constrains movements to just two axes, eliminating the tilted loudspeaker syndrome associated with ball and socket systems. It does not require the installer to engage with any threaded fastening device to retain/tension the loudspeaker in the desired position and it provides “clicks” that correspond to specific degrees of movement, that when counted, telegraph just how far the loudspeaker has been moved along either of two axes (e.g. 10 clicks equal 30 degrees of movement) or in some combination of the two. Simply using their hands alone the installer is able to position/re-position the loudspeaker exactly into the desired orientation. Subsequently, directing a plurality of loudspeakers using the same “click-count” procedure ensures that all are aligned exactly the same. The invention(s) described also enable much larger angular movements than do more traditional approaches while keeping the loudspeaker mounted closely to the wall&#39;s surface. In addition, because it is possible for an unauthorized party to reposition the loudspeaker the design incorporates a locking feature that rigidly locks the loudspeaker into the position specified by the original installer. The nature of the design also provides for simple “scaling” of the design for larger (e.g. heavier) or smaller systems and a hollow shaft is provided that facilitates wire routing. 
       SUMMARY 
       [0007]    This invention provides an easily managed wall-mounted loudspeakers system mount so that the loudspeaker direction of sound propagation can be directed toward a predetermined target and to be able to quickly and reliably match the desired angularity between two or more related wall-mounted loudspeakers. 
         [0008]    This invention is a mounting system for a loudspeaker system that is capable of positioning and re-positioning the box-like device of the loudspeaker without requiring the use of any retaining/tensioning fasteners. A bracket facilitates constraining the positioning and repositioning for the roll and pitch axes while simultaneously providing audible feedback angular movement indication that enable vertical and horizontal orientation with respect both to the installation environment and to match its positioning to other like installed systems.

         [0065]      FIG. 11  is a perspective, zoomed in view illustrating the primary support bracket planar slots. 
         [0066]      FIG. 12  is a perspective view illustrating the “T” shaped knuckle. The invention is an articulated mounting system that employs semicircular and circular arrays of closely mated ribs and slots, with the semicircular rib/slots being arrayed cylindrically around a hypothetical x-axis (“pitch axis”) which typically aligns with the largest or longest dimension of any particular assembly) and the circular rib/slots in a planar fashion on a face perpendicular to the y-axis (“roll axis”). The semicircular cylindrical set of ribs/slots are arrayed around one axis of a “T” shaped “knuckle” that fits into a matching and also cylindrical “cradle”, where the ribs reside on an outside annular surface of the knuckle and the slots on the inside surface of the cradle. This corresponds with the pitch axis. The flat or planar array rib/slots control rotations around a roll axis. These elements are held in the desired proximity to one another by additional mechanisms or feature sets that apply alignment and variable amounts of retaining force. 
         [0067]      FIG. 13  is a perspective and cut away view illustrating the “T” shaped knuckle. One key to the invention&#39;s features is the ability to variably and predictably articulate the engagement and/or disengagement of the mating rib arrays around pitch and roll axes. These arrays are held in contact with one another via a variable tensioning device such as a spring that by the nature of its variability allows the rib/slots to axially disengage only when a force larger than the force applied by the spring is overcome by some outside force—in this case the installer&#39;s actions to reposition the angularity of the bracket. By varying the rate of the spring and the sizes and circumference of the mating rib arrays different sizes and masses of mounted devices can easily be accommodated. 
         [0068]    To provide axial structural support for the roll axis, the knuckle is matted and inserted onto a hollow round shaft integrated into the primary bracket, via a round bearing surface. The cradle mates with and wraps around the knuckle&#39;s pitch axis such that the centerlines of both the knuckle&#39;s and the cradle&#39;s pitch axis align thereby allowing the rib/slots to engage. 
         [0069]    A hollow protruding shaft integrated into a sliding collar inserts though an oblong slot shape in the cradle that enables the sliding collar to axially rotate to the length limits of the oblong slot. When the sliding collar is inserted into the cradle&#39;s oblong slot the sliding collar is able to slide or rotate around the knuckle&#39;s pitch axis. The length of the oblong slot is the primary enabler/limiter of the bracket&#39;s pitch motions. Smooth cylindrical surfaces are formed on the inside radius of a sliding collar that are mated over matching cylindrical surfaces found on the outside of the cradle. These surfaces create the principle moveable pitch axis interface between the mounted device&#39;s enclosure assembly and the wall&#39;s “immovable” mounting surface.

         [0099]      FIG. 43  is a side, cross sectional view of an articulating bracket that shows clearances that enable rib/slot axial movement. A retaining nut features two round pins the interface firstly with match pairs of shaped slots found on one end of the hollow, flanged shaft. A tensioning force supplied by the spring cause the round pins to slide up and are rotated clockwise over a ridge, and, due to the force of the spring, when released, the round pins snap back into a recess. At this stage of the retaining nut&#39;s rotation the assembly is free to move slightly as attested by the gap. When the tensioning nut is rotated further the round pins are forced along a spiral ramp until they meet another slot at which point the round pins drop into the slot, thereby locking the assembly together causing the gap to disappear.
