Description

[Technical Field]

[0001] The present disclosure generally relates to a kit that also includes an assembly having two axes of rotation for securely and adjustably mounting a speaker, and a mount used to securely and adjustably mount such an assembly. [Background technology]

[0002] background Mounting loudspeakers to surfaces such as walls or ceilings, or to other support structures such as masts or frames, can be physically and geometrically challenging. Such mounting is particularly challenging in commercial settings, such as music venues, theaters, and music and / or video production studios, where speakers can be much heavier and larger than home speakers. Where multiple speakers are mounted, it may be desirable to mount each speaker in a particular orientation or orientation (e.g., something other than perpendicular to the surface or structure to which it is mounted). In certain adjustable mounting systems, there is an inherent tradeoff between adjustability and stability. Summary of the Invention [Problem to be solved by the invention]

[0003] Therefore, improved speaker mounting assemblies and / or systems that address one or more of the above-mentioned shortcomings and / or provide other advantages would be desirable. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0013] Detailed Description Reference will now be made in detail to the drawings in which embodiments embodying the present disclosure are shown. The detailed description uses numerical and letter designations to refer to features in the drawings. Like or similar designations in the drawings and description are used to refer to like or similar parts of the disclosure.

[0014] The drawings and detailed description provide a complete and enabling description of the disclosure, and methods and processes for making and using it. Generally, FIGS. 1-12 illustrate aspects of the subject two-axis rotation speaker mounting assembly and mounting kit that will be needed by one of ordinary skill in the art to understand, manufacture, and use the disclosed subject matter. Other aspects are described below and found in the following claims. Each embodiment shown and / or disclosed is provided by way of explanation of the subject matter, and is not a limitation of the subject matter. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made in the disclosed subject matter without departing from the scope or spirit of the present disclosure. For example, a configuration shown or described as part of one embodiment can be used with another embodiment to produce yet another embodiment.

[0015] More specifically, as shown in Figures 1-12, an example two-axis rotation speaker mounting assembly 10 may include some or all of a base portion 12, a central portion 14, a speaker portion 16, a first lockable pivot assembly 18, and a second lockable pivot assembly 20. As shown in Figure 10, assembly 10 may be mounted directly to a support S (wall, ceiling, frame, etc.), or, as shown in Figure 12, optionally, assembly 10 may be mounted to a mounting plate 22 that is itself mounted to support S.

[0016] The base portion 12 includes a base plate 24 with holes 26a-c and an upstanding flange 28. The central portion 14 includes a cylindrical portion 30 and a plate portion 32. A first lockable pivot assembly 18 connects the base portion 12 and the central portion 14 via a first shaft 34 extending through the flange 28 along an axis 36. The knob 38 can be selectively tightened or loosened by reciprocal threading on the shaft 34 (or, as shown, a jackshaft 35 secured in place by a screw 37 or other extension rotatable with the shaft 34). When loosened, the central portion 14 can rotate about the first axis 36 relative to the base portion 12; when tightened, such rotation is not permitted by axial compression along the axis 36. If desired, reciprocal friction-enhancing elements such as stops, teeth, detents, etc., can be used to define a specific amount of relative rotation and enhance the frictional grip when the knob is tightened.

[0017] The speaker assembly 16 includes a plate portion 40 and a speaker plate 42 for mounting to the plate portion with screws 44. If desired, screw holes can be located in the plate portion 40 and the speaker plate 42, allowing the parts to be mounted in more than one relative orientation, which may help provide additional mounting options. For example, FIGS. 7 and 8 show the plate 42 mounted to the plate portion 40 in two orientations 90 degrees apart. The speaker plate 42 can have multiple openings 46 (slots and / or holes) with varying spacing configured to mount multiple speakers, mounts, brackets, extension pole housings, etc., making it compatible with products from many manufacturers.

[0018] The second lockable pivot assembly 20 functions similarly to the first assembly, including a knob 48, a second shaft 50, a jackshaft 52, a screw 54 for selectively loosening and tightening the assembly along the second axis 56, and an internal thread. When loosened, the assembly 20 allows pivoting of the speaker assembly 16 relative to the central section 14 about the second axis 56. When tightened, the assembly 20 frictionally compresses the elements along the second axis 56, preventing rotation about the axis 56. A pin 58 extending circumferentially about the second axis 56 and riding in a groove 60 in the plate section 40 helps guide and align the central section 14 and the speaker assembly 16 during rotation and locking. Friction elements 62 (shown as radially extending teeth) between the plate sections 40 and 32 help define the relative positions of the parts and lock them against rotation when the assembly 20 is tightened by the knob 48.

[0019] 2A, 2B, and 2C show three possible relative positions of the central portion 14 with respect to the base portion 12, at approximately 30-degree intervals, by rotating about axis 36 and locking in place with knob 38. FIGS. 3A, 3B, and 3C show three possible relative positions of the speaker portion 16 with respect to the central portion 14, also at approximately 30-degree intervals, by rotating about axis 56 and locking with knob 48. FIG. 4 shows one possible orientation of the speaker portion 16 with respect to the base portion 12, with rotation about both axis 36 and axis 56. Thus, the assembly 10 provides easy, optimal rotation, lockable by a single lockable pivot assembly at each pivot axis. Adjustability about axis 36 and axis 56 allows the assembly to be oriented in multiple ways relative to the support S, and access to knobs 38 and 48 for tightening, loosening, adjustment, etc. is straightforward.

[0020] Base plate 24 may be attached to support S using screws 64 through any or all of holes 26a-c. As shown in FIG. 9, plate 24 is attached using two holes 26a and two holes 26b (i.e., the holes closest to the corners of plate 24) to lift speakers Sp mounted on plate 42.

[0021] However, Figures 10-12 show an optional mounting plate 22, which may provide additional ease of installation and functionality. The mounting plate 22 includes a plate 66 with peripheral holes 68 and slots 70 for mounting to a support S (again, a wall, ceiling, frame, structure, etc.). The base plate 24 may be slid onto and held in a U-shaped lip 72 on the plate 66, which has an L-shaped (undercut) side 74. The base plate 24 may be slid with either side 24a or side 24b contacting the bottom 76 of the U-shaped lip 72. Figures 11A and 11B show the alternative relative orientation (the orientation of the mounting plate 22 is reversed between the figures).

[0022] Plate 66 includes four screw holes 78 positioned to receive either holes 26a or 26b, depending on which side 24a or 24b is slid onto the U-shaped lip to contact bottom 76. A threaded screw 80 may extend through either hole 26a or 26b and thread into hole 78 to secure base plate 24 to plate 66. If desired, holes 78 may be symmetrically positioned, and only one set of holes 26a or 26b (also symmetrically positioned) may be employed. A vibration-damping foam layer 82 may be positioned on the bottom of plate 66 and, when secured to support S, generally reduces vibrations caused by speakers Sp or other acoustic items in the room.

[0023] The above structures therefore provide one or more examples of a two-axis rotating speaker mounting assembly that may be used to mount a speaker to a support structure such that it can pivot about two axes relative to the base / support in a desired orientation and be securely fixed in a desired orientation, with or without an additional mounting plate.

[0024] Although preferred embodiments of the present invention have been described above, it should be understood that all equivalent implementations of the present invention are within the scope and spirit of the present invention. Accordingly, the illustrated embodiments are presented by way of example only and are not intended as limitations on the present invention. Thus, while specific embodiments of the present invention have been described and shown, it will be understood by those skilled in the art that the present invention is not limited thereto, as many modifications may be made. Accordingly, all embodiments are considered to be encompassed by the present invention as may fall within the literal scope or equivalent scope of the appended claims.
