Methods, Systems, and Apparatus for Mounting and Attaching a Device to a Surface

1 . A corner mounting assembly unit comprising:

a mounting frame including at least: (1) a mounting guide shell formed as one unit;

and having at least two windows on opposing faces and a top opening on a face perpendicular to the two opposing faces, (2) a top plate, and (3) a back plate; and

a retainer having a retention part providing retaining force a more than one position allowed for by the mounting guide shell, the retainer including at least: (1) a screw, (2) a retaining clip, (3) a toggle leg, (4) a spring, and (5) a pivot.

2 . The corner mounting assembly unit of claim 1 , wherein the mounting guide shell is a molded element fabricated by injection molding.

3 . The corner mounting assembly unit of claim 1 , wherein the at least two windows are disposed approximately orthogonal to each other.

4 . The corner mounting assembly unit of claim 1 , wherein the at least two windows have geometries selected from the group consisting of square shapes, rectilinear shapes, oblong shapes, triangular shapes, and elliptical shapes.

5 . The corner mounting assembly unit of claim 1 , wherein the mounting guide shell includes a curved internal surface configured to allow the toggle leg to freely move between the at least two windows.

6 . The corner mounting assembly unit of claim 1 , wherein the top plate is formed of steel to provide greater torque resistance before failure.

7 . The corner mounting assembly unit of claim 1 , wherein the back plate includes an air-sealing bulkhead feature for integration with an enclosed loudspeaker system.

8 . The corner mounting assembly unit of claim 1 , wherein the screw comprises a head part configured to receive a tool, a neck part, a thread part, and an end part.

9 . The corner mounting assembly unit of claim 8 , wherein the neck part prevents the toggle leg from traveling beyond a predetermined point before the head part to avoid damage from over-driving.

10 . The corner mounting assembly unit of claim 8 , wherein the end part includes a break-part for retaining the screw via interaction with molded features in a bottom of the mounting guide shell.

11 . The corner mounting assembly unit of claim 1 , wherein the retaining clip is disposed in a groove of the screw to prevent the screw from backing out of the mounting guide shell.

12 . The corner mounting assembly unit of claim 1 , wherein the toggle leg is configured to move between a deployed position extending horizontally relative to a longitudinal axis of the screw and a stowed position aligned approximately parallel to the longitudinal axis of the screw.

13 . The corner mounting assembly unit of claim 12 , wherein the toggle leg includes a tube feature configured to contact the screw on both sides to relieve force from the pivot.

14 . The corner mounting assembly unit of claim 1 , wherein the toggle leg is formed of sheet metal having a square tube configuration.

15 . The corner mounting assembly unit of claim 1 , wherein the spring is a double torsion spring that spans a width of the screw and applies force to the toggle leg causing rotation around the pivot.

16 . The corner mounting assembly unit of claim 15 , wherein the spring comprises a base part, at least one torsion part having a variable outside diameter, and at least one leg part.

17 . The corner mounting assembly unit of claim 15 , wherein the torsion spring is tuned to maintain the toggle leg perpendicular to the screw regardless of orientation of a mounted object.

18 . The corner mounting assembly unit of claim 1 , wherein the pivot includes arms for retaining the pivot to the toggle leg and shoulders for reducing play in the spring.

19 . The corner mounting assembly unit of claim 1 , wherein the assembly unit is configured to support up to 35 pounds of vertical load per fastener for through-panel installation in drywall substrate.

20 . The corner mounting assembly unit of claim 1 , wherein the pivot is mounted to the screw and configured to travel along a vertical axis of the screw via threaded engagement.
