Description




TECHNICAL FIELD OF THE INVENTION




The present invention relates to acoustic panels, and more particularly to foam-type acoustic panels.




BACKGROUND OF THE INVENTION




It has long been known that acoustic panels can be employed to change the acoustic qualities of a space, such as a room, studio, theater or stadium. A wide variety of acoustic-affecting materials, such as acoustic ceiling tiles and carpet are employed even in interior or exterior spaces (e.g. room, pool area) of houses, offices and commercial spaces where the acoustic characteristics of the space are not that critical. However, certain situations exist where the acoustic characteristics of a space are sufficiently critical so as to require more extraordinary treatment and devices to achieve the desired acoustic quality. Such environments include places such as music practice rooms, concert venues, recording studios and broadcast facilities.




To achieve the desired acoustical characteristics of an acoustic quality critical space, musicians and those who own the sound-critical spaces have long employed a variety of acoustic devices, such as acoustic foam panels to enhance the acoustic qualities of the space. Examples of such acoustic foam panels can be found at the Applicant's web site at www.auralex.com. A review of Applicant's web site discloses that these acoustic foam panels come in a wide variety of shapes and sizes. Although many of the foam panels are designed for general purpose use, some of the foam panels are designed for more special applications, or to perform more specific functions. Different types of panels that exist include things such as base trap panels that are designed especially for absorbing low-range, base sounds; corner panels that are designed to fit easily into corners of rooms; broad-band absorbers that are designed to absorb sound over a wide range of frequencies; and wedge-type absorbers that are especially useful for spot treating certain areas in spaces.




It should also be noted that acoustic foam panels employ a wide variety of facial configurations, with some facial configurations being adapted to perform certain functions, while other facial configurations are designed with primarily esthetic considerations in mind. Other sound panels are designed to not only absorb sound, but also to defuse sound over a given area. Further, some sound-absorbing panels are used primarily as sound and vibration insulators that are placed between a pair of hard surfaces, such as a platform and a floor to acoustically isolate two hard members from each other, to thereby reduce the likelihood that vibrations of one hard member will cause vibrations in the second hard member. Further, hard and/or dense, non-foam type acoustic panels exist that are used primarily to provide sound barriers between adjacent spaces.




One factor that has influenced the design and usability of sound panels is the electronic revolution. In times as recent as the 1970s and 1980s, a musician or other sound recording person who desired to obtain a studio-quality recording was often forced to make his recording in a specially-designed studio. This requirement existed not so much because of the acoustic properties of the room, but rather resulted from the significant expense required to obtain studio-quality electronic recording equipment, such as multi-track tape recorders, mixers and the like. Recently, sound recording technology has changed from the prior-used analog equipment to digital recording equipment. Concurrently, low cost personal computers have become sufficiently powerful so as to be able to process large amounts of digital data. These two technological developments have resulted in studio-class, high quality recording equipment being obtainable at a price that is affordable by persons such as musicians, radio personalities, voice talents and recording engineers. As such, the relatively low cost and small size of current state-of-the-art recording equipment has permitted many musicians, voice talents and other persons to set up “home studios” in their homes, apartments or office spaces, that have electronic recording equipment that is capable of making high-quality “studio grade” recordings.




Even though the declining price of studio-quality recording equipment has permitted the creation of such “home studios,” room acoustical quality issues still must be addressed by the home studio owner. Prior to the instant invention, the problem of acoustic quality was handled in a manner similar to the manner in which it was handled in professional studios. That is, the home studio owner would purchase acoustic panels, such as the foam panels shown at www.auralex.com, and install these panels within the home studio to achieve the desired acoustical characteristics of the space.




Although the installation of traditional foam panels within a room of the user's home, has the capability of providing the user with an acoustically, highly-functional studio, room for improvement still exists. One area in which room for improvement exists relates to the utilization of the living areas and space within the user's home. As will be appreciated, a room that is outfitted as a studio, and that contains walls having foam panels thereon, may be aesthetically undesirable to use for purposes other than a studio.




Although the installation of panels in a room to cause the room to be dedicated for use as a studio may be quite acceptable to those having dwellings with multiple or extra rooms, it may cause a less than desirable situation for a user having limited rooms or space within his dwelling. For example, room size considerations may dictate that the living room is the most suitable room within the user's dwelling for use as a studio. However, the user may not wish to panel his living room in acoustic foam, since this may leave the living room aesthetically unsuitable for use as a living room to entertain guests. Therefore, it will be appreciated that situations such as those described above would be improved if the acoustic panels were designed to be easily installable and removable, so that the panels could be installed when the living room was being used as a studio, but uninstalled and stored out-of-sight when the user desired to use the room as a normal living room.




One object of the present invention is therefore to provide an acoustic panel that lends itself to temporary installation in a room, while providing easy de-installation.




SUMMARY OF THE INVENTION




In accordance with the present invention, a foam-type acoustic panel is designed to be mountable on a stand having a shaft. The acoustic panel includes a main body portion. The main body portion has a first end, a second end, a front surface, a rear surface, a top surface, a bottom surface, and first and second interlocking members. The first and second interlocking members define a multi-segment cut that extends between the top and bottom surface. The multi-segment cut includes a first end disposed at one of the front and rear surfaces, and a second end disposed interiorly of the other of the front and rear surfaces. The second end of the multi-segment cut defines an elongated aperture extending between the top and bottom surface for receiving the shaft of the stand.




Preferably, first and second interlocking members are movable between a disengaged position and an engaged position. In the disengaged position, a shaft of a stand can be received into the elongated aperture by passing the shaft laterally through the multi-segment cut. In the engaged position, the shaft is engaged by the acoustic panel with sufficient frictional force to maintain the acoustic panel at a chosen vertical position on the shaft.




Additionally, in the preferred embodiment of the present invention, the first interlocking member includes a first portion extending in a first direction generally non-perpendicular to a plane defined by one of the front and rear surfaces. The first interlocking member also includes a second portion extending in a direction generally perpendicular to the first direction, and a third portion extending in a third direction defining an acute angle to the second direction. The second interlocking member includes a first portion for receiving the first portion of the first interlocking member, and a second portion for receiving the second portion of the first interlocking member. Further, the second interlocking member also includes a third, partly-cylindrical portion for receiving a bulbous male portion of the third portion of the first interlocking member.




One feature of the present invention is that the acoustic panel of the present invention can include a first end interlocking member that is disposed at the first end of the main body portion of the acoustic panel member; and a second interlocking member that is disposed at the second end of the main body portion. Through this arrangement, the acoustic panel of the present invention can comprise a first acoustic panel that is capable of being joined to a second acoustic panel by matingly engaging the first end interlocking member of the first acoustic panel with the second interlocking member of the second acoustic panel, to place the first and second acoustic panels in a co-planar end-to-end interlocked relation. Through this feature, the user can create a gapless, multi-segment panel having a length that may be two or more multiples of the length of any particular acoustic panel. Through this, the user gains enhanced flexibility in setting up acoustic panels, so that the acoustic panels of the present invention can be easily transferred from room to room by adding or removing acoustic panels as necessary to create an array of acoustical panels that is suitable for the particular sized room in which the acoustic panels are being used.




Another feature of the present invention is that the multi-segment cut includes a first end disposed at one of the front and rear surfaces, and a second end disposed interiorly of the other of the front and rear surfaces. Through this arrangement, the multi-segment cut can receive the shaft of the stand, without the cut extending completely through the panel. This arrangement helps to make the panel more structurally strong, and secure; and easier to assemble, as the shaft is preferably engaged by the acoustic panel near the middle (when measured from side to side) of the panel. As the shaft engages the acoustic panel near its middle, the weight of the panel is balanced relative to the shaft, thus making the stand and panel combination more securely positionable.




These and other features of the present invention will be apparent to those skilled in the art upon review of the best mode of practicing the present invention described below in connection with the following drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT




Acoustic panel


10


of the present invention is best shown in

FIGS. 1 and 5

as being mountable to a stand


12


, such as a microphone stand. The stand


12


includes a base for supporting the stand


12


on the ground or other surface, and a vertically extending, generally cylindrical shaft. Although most microphone shafts are cylindrical and telescoping, it will be appreciated that the shaft can be configured in any one of a variety of cross-sectional shapes. Although a microphone


16


is shown as being mounted to the top of the stand


12


, the microphone


16


is largely superfluous of the present invention, and is provided in the drawings for illustrative purposes only.




The acoustic panel


10


includes a main body portion


24


, a first end portion


26


, and a second end portion


28


. The main body


24


is generally unitarily constructed so that it comprises one piece. However, the first and second end portions


26


,


28


are detachably coupled to the respective first and second ends of the main body portion


24


. Main body portion


24


, along with the first and second end portions


26


,


28


are preferably made from the same sound absorbing foam material. Although a variety of foams can be used, a preferred foam is the Assignee's STUDIO FOAM™ foam material, panels of which are available at www.auralex.com. Other sound-absorbing acoustic foam materials also exist that will also serve as suitable materials from which the acoustic panel of the present invention can be made, although such other foams will likely not perform quite as well as the Assignee's proprietary STUDIO FOAM™ product. When constructing the panel, the foam should be chosen based on a balancing of factors such as sound-absorption characteristics, cost, and working characteristics.




The main body portion


24


includes a first end


34


, and a second end


36


. In the embodiment shown in

FIGS. 1 and 5

, the first and second end


34


,


36


comprise the side ends of the panel's main body portion


24


. However, it will be appreciated that the particular orientation of the main body panel


10


is somewhat arbitrary. Therefore, even though first end


34


is shown as the left side, the main body portion


24


could be rotated 90° so that the first end


34


is the top of the main body portion


24


; rotated 180° so that the first end


34


is disposed on the right side of the main body portion


24


; or rotated 270° so that the first end


34


serves as the bottom of the panel's main body portion


24


. As will described in detail below, the first end


34


and second end


36


are configured to be jig-saw-puzzle-piece shaped (in a cross-section) so that the first end


34


and second end


36


can be interlocked with end panel members, such as first end panel member


26


and second end panel member


28


, respectively; or with an adjacent, co-planerly-disposed second foam acoustic panel (not shown).




Additionally, the main body portion


24


includes a generally planar top surface


38


, a generally planar bottom surface


40


, and a generally planar rear surface


42


. However, the front surface (or facia)


44


is not planar. Rather the front surface


44


comprises a series of parallel wedges, with each wedge being generally triangular in cross-section, and including a raised edge portion


48


and a relatively depressed valley portion


50


. The wedge-shaped surface of front facia


34


is the surface that is designed to “face” the sound-generating apparatus, such as the musical instrument within the room in which the acoustic panel


10


is being used. The wedge shape of facia


44


is designed to enhance the sound absorbing quality of the acoustic panel


10


, both by providing a means for capturing reflected sound waves, and also for increasing the sound absorbing surface area of the acoustic panel


10


. Both of these characteristics help to enhance the sound absorbing qualities of the acoustic panel


10


. Although the facia


44


is shown as having a wedge-shaped facia, other facia designs are also useable. For example, other facia shapes include shapes such as pyramids, irregular wedges, egg crate-like shapes or the like. Examples of various facia configurations can be viewed on the Applicant's web site, or by viewing sound foam products sold by the Assignee's competitors.




Although the main body portion


24


is a unitary member, the unitary main body portion


24


includes a multi-segment cut


62


that extends partially through the main body portion


24


, from the back surface


40


, to a point within the interior of the main body portion


24


. The multi-segment cut


62


creates a first


56


and a second


60


interlocking member, that permit the main body portion


24


to be moved between: (1) an engaged position, as shown in

FIG. 1

, wherein the main body portion


24


is generally co-planar; and (2) a disengaged position (not shown) wherein the interlocking members


56


,


60


are disengaged. When in the disengaged position, the shaft


14


of the microphone can be moved laterally from the first end of the multi-segment cut


62


to the vertically extending cylindrically-shaped aperture


64


that defines the second end of the multi-segment cut


62


, thus permitting the shaft to be inserted within the vertically extending aperture


64


.




When the interlocking members


56


,


60


are in their disengaged position, the acoustic panel


24


main body portion (and any other elements attached thereto) can be moved vertically along the shaft


14


, to vertically position the acoustic panel


10


on the shaft


14


. When the first and second interlocking member


56


,


60


are in their engaged position, the aperture


64


cooperates with the strength of the interlock created by the interlocking member


56


,


60


to impart sufficient frictional engagement between the foam surface that defines the cylindrical wall


66


of the stand-receiving aperture


64


, and the axially extending, radially outwardly facing surface of the stand


14


, to maintain the acoustic panel


10


at its appropriate vertical position on the stand


14


. The frictional engagement between the stand


14


and the cylindrical wall


66


is sufficiently great so that the desired vertical position of the acoustic panel


10


can be maintained even if, as shown in

FIG. 1

, no support underlines the planar bottom surface


40


of the main body portion


24


of the panel


10


.




The multi-segment cut


62


includes a plurality of segments that define the first and second interlocking members


56


,


60


. As best shown in

FIG. 3

, the first segment


67


has its first end at the rear surface


42


of the acoustic panel main body portion


24


. The first segment


67


extends at an angle that is not perpendicular to the plane of the rear surface


42


. More particularly, the first segment


67


intersects the plane of the rear surface


42


on an acute angle (angle A) or obtuse angle (angle B) depending upon how the angle is viewed. In any event, segment


67


is not perpendicular to the rear planar surface


42


.




The second end of the first segment


67


has a second end that terminates at the first end of second segment


68


. Second segment


68


extends generally perpendicularly to first segment


67


, and has a second end that terminates at the first end of third segment


72


. Third segment


72


extends in a generally spaced, parallel relation to first segment


67


, and is generally shorter than first segment


67


. The second end of the third segment


72


terminates at the first end of fourth segment


74


. Fourth segment


74


includes a partially circular (in cross-section) section that segues into a straight section that extends generally parallel to the rear planar surface


42


.




The second end of fourth segment


74


terminates at a first end of fifth segment


78


. Fifth segment


78


extends generally perpendicularly to the plane of the rear surface


42


, and terminates at the first end of sixth segment


82


. Sixth segment


82


extends in a direction generally parallel to third segment


72


and first segment


67


. The sixth segment


82


terminates at the first end of seventh segment


86


. Seventh segment


86


extends generally parallel to the plane of the rear surface


42


of the main body portion


24


, and also generally parallel to the straight portion of the fourth segment


74


.




The second end of seventh segment


86


terminates at a first end of the eighth segment


88


. Eighth segment


88


extends generally parallel to second segment


68


, and generally perpendicular to first segment


67


. The eight segment


88


terminates at the first end of ninth segment


92


. Ninth segment


92


extends generally parallel, and co-linear with the first segment


67


, and also generally parallel to the third segment


72


and sixth segment


82


. The second end of ninth segment


92


, which also comprises the end of the multi-segment cut


62


, terminates at the generally circular (in cross-section) and generally cylindrical (in shape) stand-engaging aperture


64


.




The various segments


67


,


68


,


72


,


74


,


78


,


82


,


86


,


88


, and


92


define the first and second interlocking members


56


,


60


. First interlocking member


56


includes a first portion


100


that is defined generally by second segment


68


, eighth segment


88


, and part of seventh segment


86


. The first portion of interlocking member


56


extends generally at an angle perpendicular to angle A, and generally obtuse (when compared to angle A) to the plane of the rear surface


42


of the main body portion


24


. The second portion


112


is defined generally by third segment


72


, sixth segment


82


, a portion of seventh segment


86


and fifth segment


78


. The second portion extends generally perpendicular to the major direction of extent of the first portion


110


, and also extends in a direction generally parallel to the first and ninth segments


67


,


92


. The third portion


106


extends in a direction generally parallel to the plane


42


of the rear surface, and includes a bulbous male portion that is defined by the partly cylindrical portion of fourth segment


74


. Additionally, the third portion is partly defined by fifth segment


78


. As will be explained in more detail below, the bulbous, male, partly circular (cylindrical) head of third portion


106


is designed interlock into the second interlocking member


60


.




The second interlocking member includes a first portion


110


that is generally female in configuration for receiving the first portion


100


of the first interlocking member. Second portion


112


of the second interlocking member is that portion of the second interlocking member


60


that is designed for receiving the second portion of the first interlocking member


56


; and the third portion


116


of the second interlocking member is that portion of the second interlocking member


60


that is designed for receiving the third portion


106


of the first interlocking member


56


, including the bulbous male portion thereof.




As stated above, the first


56


and second


60


interlocking members are movable between an engaged position, as shown in

FIG. 3

, and a disengaged position (not shown). In the disengaged position, the first and second interlocking members are not matingly engaged, so that the multi-segment cut


62


becomes a multi-segment slot. Because of the flexibility of the foam material from which the acoustic panel is made, the first and second interlocking members


56


,


60


can be pivotably moved with respect to each other, generally about a pivot point defined by aperture


64


, so that the first and second interlocking members


56


,


60


are disengaged. When so disengaged, the shaft portion


14


of the stand


12


can be passed through the multi-segment cut


62


, so that it can be moved from a position rearwardly of the rear surface


42


, inwardly relates to the panel


10


, until the shaft


14


is disposed within the shaft receiving aperture


64


. As will also be appreciated, when the first and second interlocking members


56


,


60


are disengaged, the first


100


, second


102


, and third


106


portions of the first interlocking member


56


are released from their adjacent positioning with the respect to first


110


, second


112


, and third


116


portions of the second interlocking member, so that the path followed by the shaft to the aperture


64


will generally follow a path defined by first cut segment


67


, and ninth cut segment


92


, as no part of the first portion


100


would extend between the first and ninth segments


67


,


92


within the first and second


56


,


60


interlocking members are fully disengaged.




After the shaft


64


is inserted into aperture


64


, the first and second interlocking members


56


,


60


are pivotably moved toward each other about pivot axis defined by shaft receiving aperture


64


, until such time as the first and second interlocking members


56


,


60


are fully engaged again, as shown in FIG.


3


.




Due to the configuration of the first and second interlocking members, it is highly unlikely that the first and second interlocking members


56


,


60


will become disengaged except in the event of specifically directed force applied to the first and second interlocking members


56


,


60


, to disengage them. Thus, under normal circumstances, the configuration of the first and second interlocking members


56


,


60


, will maintain the first and second interlocking members in an engaged position. Further, the configuration of the first and second interlocking members


56


,


60


discourages lateral relative movement of the first and second interlocking members


56


,


60


, thus enabling the main body portion


24


, and in particular, the foam


66


defining the cylindrical wall of shaft receiving aperture


64


to securely grip the shaft


64


.




This grip is sufficiently secure so that the grip provided by the sizing of the aperture


64


, the engagement of the first and second interlocking members


56


,


60


, and the normal co-efficient of friction of the foam material that comprises the cylindrical walls


66


cooperate to securely hold the main body portion


24


of the acoustic panel in its desired vertical position. As shown in

FIG. 1

, the vertical position of the acoustic panel can be maintained in its desired vertical position, even when the bottom surface


40


of the acoustic panel is unsupported, and hence “hanging in mid air”.




Turning now to

FIG. 4

, a cross-sectional view of first end


34


and first end panel


26


are shown, to illustrate the mating relationship between the two pieces. As discussed above, first end panel


26


is detachably matable to the first end


34


, so that the first end panel


26


can be selectively removed, or attached as necessary. Although the acoustic panel


10


benefits by the inclusion of the first end panel


26


, especially if acoustic panel


10


is being placed in a corner, the end panel


26


is not necessary in all situations. One such situation is when two or more acoustic panels are joined together to form an end-to-end co-planar array of panels.




The configuration of the mating surfaces of the first end panel


26


and first end


34


are best described with respect to the series of line segments (in cross-section) or planes (in 3-D) that form the mating intersecting surfaces of the first end panel


26


and first end


34


. As will be noted from the drawing shown in

FIG. 4

, mating surfaces


26


of the first end panel fit flushly against the corresponding mating surfaces of the first end


34


, so that full surface-to-surface engagement exists along the “end panel cut line” (plane)


150


therebetween. The intersection of the surfaces can properly be referred to as an end panel cut line, since the normal method of manufacturing the panel


10


is to create the end panel


26


by starting with a rectangularly-cuboid foam piece having a squared-offend and employing a saw blade to make the cut


150


to separate the first end


34


and first end panel


26


into separate and separable pieces.




The first end panel cut line


150


includes a first angled segment


156


that extends perpendicular to first segment


67


of main body portion cut line


62


. Additionally, first angle segment


156


is generally not perpendicular to the plane of rear surface


42


. The first angled segment


156


terminates at its second end at a partly circular (partly cylindrical) bulbous segment


158


. The bulbous segment


158


includes a diameter at its widest extent that is generally wider than the distance measured between intersection point between the first angled segment


156


and bulbous segment


158


; and the intersection of the first bulbous segment


158


and the first end of the third segment


160


. This difference in diameters permits the bulbous nose


164


of the first portion of the first end panel


156


to lockingly engage the female receiving cavity


66


of the first end


34


; and thereby lockingly engaging the first end panel


26


to the first end


34


. The third segment


160


extends in a direction generally perpendicular to the plane of the rear surface


42


, and terminates at its second end in a first segment


162


, that extends generally parallel to the plane of the rear facing surface


42


. As will be noted, the configuration of the end panel cut line


150


causes the first end panel


156


to have a jig-saw-puzzle-like engaging configuration for lockingly, but removably engaging the first panel


26


to the first end portion


34


.




The mating configuration between the second end panel


28


and second end


36


of the main body portion is shown in FIG.


2


. It will be noted that second end panel cut line


250


has a generally identical shape to the first end panel cut line


150


. As such, the second end panel cut line


250


includes a first angled segment


256


that is disposed at an angle to the plane of the rear surface


42


that is generally identical to the angle at which the first angled segment


156


is disposed relative thereto.




A second bulbous segment


258


is generally an identical shape, diameter and radius of curvature to the first bulbous segment


158


of the first end panel


26


. Finally, the third segment


260


is generally similar in orientation, direction of extent, and length to the third segment


160


of the first end cut line


150


.




Through this identical “cut line” configuration, the second end panel


36


is generally identically shaped in cross-section to the first end panel


26


, including the provision of a bulbous nose


264


that is sized to be received by a female receiver


266
