This disclosure relates to a stand that supports a loudspeaker cabinet.
Stage performers sometimes mount one loudspeaker cabinet above another loudspeaker cabinet. The lower loudspeaker cabinet may be a subwoofer, and the upper may be a mid-high range loudspeaker. Usually the upper loudspeaker cabinet needs to be mounted several feet above the lower loudspeaker cabinet. In some approaches, a mounting pole is held upright by the lower loudspeaker cabinet, and the upper loudspeaker cabinet is lifted up and placed on the pole. This action requires the user to hold a heavy loudspeaker cabinet (weighing perhaps 45-50 pounds) up at about eye level while aligning a small opening in the bottom of the cabinet with the top of the pole. This exercise is physically demanding, and may be dangerous.
The subject loudspeaker cabinet stand is adapted to support an upper loudspeaker cabinet above a lower loudspeaker cabinet. The stand is constructed such that it can be stowed on or in the lower loudspeaker cabinet. The stand is also constructed such that when it is deployed it engages with the lower loudspeaker cabinet. The stand includes a structure that is able to support the upper loudspeaker cabinet above the lower loudspeaker cabinet when the stand is deployed.
All examples and features mentioned below can be combined in any technically possible way.
In one aspect, a stand that is adapted to support an upper loudspeaker cabinet relative to a lower loudspeaker cabinet includes a first structure that is constructed and arranged to be directly coupled to a first portion of the lower loudspeaker cabinet in a stand stowed position wherein the stand is stowed on or in the lower loudspeaker cabinet, and a second structure that is constructed and arranged to be directly coupled to a second portion of the lower loudspeaker cabinet in a stand deployed position. The stand is supported by and extends above the lower loudspeaker cabinet. The stand is further constructed and arranged to support the upper loudspeaker cabinet when the stand is in the deployed position.

The third structure of the stand may include an interface structure that supports the upper loudspeaker cabinet. The stand may include a platform that includes the interface structure. The stand may have multiple legs that support the platform. The interface structure may include a tapered recess in the top of the platform. The tapered recess may include an annular recess bounded by inwardly-tapered outer walls and outwardly-tapered inner walls. The inward taper of the outer recess walls may be greater than the outward taper of the inner recess walls. The assembly may further include an interface coupling member that is adapted to be coupled to the upper loudspeaker cabinet and comprises an annular wedge-shaped projection that is shaped to fit into the tapered recess. Each leg may comprise a wedge at one end thereof At least one leg may comprise a channel along a length of such leg and that is constructed and arranged to receive an electrical cord therein. The stand may have two legs that depend from opposite ends of the platform, and the bass loudspeaker cabinet may have a shelf that is constructed and arranged to support the platform in the stand stowed position, and two recesses, the recesses located below and adjacent to each end of the shelf, wherein in the stand stowed position one leg of the stand is received in each recess.
In another aspect, an assembly that is adapted to support an upper loudspeaker cabinet includes a bass loudspeaker cabinet and a stand comprising two legs that depend from opposite ends of a platform. The stand includes a first structure that is constructed and arranged to be directly coupled to a first portion of the bass loudspeaker cabinet in a stand stowed position wherein the stand is stowed on or in the bass loudspeaker cabinet, and a second structure that is constructed and arranged to be directly coupled to a second portion of the bass loudspeaker cabinet in a stand deployed position wherein the stand is supported by and extends above the bass loudspeaker cabinet. The second portion of the bass loudspeaker cabinet comprises receiving pockets, and the second structure of the stand comprises a wedge at an end of each leg opposite the platform. Each of the wedges is constructed and arranged to be received in a receiving pocket of the bass loudspeaker cabinet. The stand has a tapered recess interface structure on the top of the platform. The interface structure is constructed and arranged to be coupled to and support the upper loudspeaker cabinet when the stand is in the deployed position. The bass loudspeaker cabinet comprises a shelf that is constructed and arranged to support the platform in the stand stowed position, and two recesses, the recesses located below and adjacent to each end of the shelf, wherein in the stand stowed position one leg of the stand is received in each recess. The tapered recess of the stand's platform may comprise an annular recess bounded by inwardly-tapered outer walls and outwardly-tapered inner walls, wherein the inward taper of the outer recess walls is greater than the outward taper of the inner recess walls, the assembly further comprising an interface coupling member that is adapted to be coupled to the upper loudspeaker cabinet and comprises an annular wedge-shaped projection that is shaped to fit into the tapered recess of the platform.
The subject stand is adapted to support an upper loudspeaker cabinet above a lower loudspeaker cabinet. The stand is constructed such that it can be stowed on or in the lower loudspeaker cabinet when the stand is not in use. The stand is also constructed such that when it is deployed it engages with and extends above the lower loudspeaker cabinet. The stand includes additional structure that supports the upper loudspeaker cabinet above the lower loudspeaker cabinet. This additional structure can be part of a platform that is supported above the lower loudspeaker cabinet. The platform allows the user to place the upper loudspeaker on the stand without precisely aligning the upper loudspeaker with a corresponding mating mechanism on the stand, such that the weight is supported by the stand until the loudspeaker mates with the stand. For example, the stand and upper cabinet can include mating interface structures. The upper cabinet can be slid onto the platform of the stand until these structures engage. The act of engaging the upper loudspeaker on the stand is thus decoupled from that act of having to hold up the substantial weight of the upper loudspeaker.
An example of a loudspeaker cabinet stand 10 is shown in
Wedges 13 and 15 may be mirror images of one another. Wedge 13 is shown in detail in
As shown in
In one non-limiting example, power and/or information signals (e.g., an audio signal) may be-provided to the upper loudspeaker via a mating mechanism in the stand. This can be useful if the upper loudspeaker includes an integral amplifier, which requires electrical power in order to operate. Power and/or information signals can be provided over a cord that can be but need not be located in channel 40. The provision of power and/or information signals to an upper loudspeaker that is stacked over a loudspeaker base is further disclosed in U.S. Pat. No. 7,319,767, the disclosure of which is incorporated herein by reference in its entirety.
Stand 10 further includes recess 50, as shown in
Interface structure 24 is shown in detail in
A non-limiting example of a lower loudspeaker cabinet 60 is shown in
A partial assembly 80, including a lower loudspeaker cabinet 60 and a deployed stand 10 that is adapted to support an upper loudspeaker cabinet, is shown in
In order to properly couple upper loudspeaker cabinet 100 to interface structure 24 of stand 10, the upper loudspeaker cabinet can be specifically designed to include a complementary projecting coupling structure. This same complementary structure can be provided as part of an interface coupling member 110 (see
Interface coupling member 110, as shown in more detail in
The same complementary wedge and recess based coupling can be accomplished in other manners. For example, projection 112 or a similar wedge-shaped structure can be directly built into the bottom of upper loudspeaker cabinet 100 rather than being part of separate member 110. In this case, coupling can be accomplished without separate member 110.
As an alternative, the projection could be part of the stand rather than the upper loudspeaker cabinet, in which case the projection-receiving receptacle would be in the upper loudspeaker cabinet or in member 110 that was engaged with the upper loudspeaker cabinet. Also, other alternative manners of accomplishing an interfitting projection and receptacle at the mating surfaces of the stand and the upper loudspeaker cabinet are contemplated. Non-limiting examples include: wedge/receptacle pairs with shapes other than as illustrated in the drawings, and projections that are not wedge shaped but still accomplish a tight fit into a similarly-shaped receptacle.
Alternative arrangements are contemplated. For example, the stand can be stowed within rather than on the outside of the lower loudspeaker cabinet. This could be accomplished by including in the lower loudspeaker cabinet a pocket that is sized and shaped to stow the stand. Also, the stand does not need to have multiple legs and a platform. For example, the stand could be a pole that is able to be stowed in the lower loudspeaker cabinet, such as in a cylindrical blind hole in the cabinet (not shown in the drawings). Both the lower and upper loudspeaker cabinets would in this case include interface structures that allowed the pole to be coupled to them, in the deployed position. Such interface structures typically but not necessarily include complementary structures (e.g., pole-shaped recesses) on the stand and the respective loudspeaker cabinet. Such structures can be a tapered recess with a shape that matches an end of the stand, so as to create a tight fit,
A number of implementations have been described. Nevertheless, it will be understood that additional modifications may be made without departing from the scope of the inventive concepts described herein, and, accordingly, other embodiments are within the scope of the following claims.
