[0001] The invention relates to stands for mounting loudspeakers, and particularly for mounting
loudspeakers on the ceiling of the listening area. Where the term stand refer to the
type of product, consisting of supports designed to host loudspeakers at a different
height from the floor level.
[0002] Loudspeakers are normally mounted at the periphery of a listening area to direct
sound output from the speakers towards a central point; this type of speaker arrangement
is referred to hereinafter as a 'convergent' configuration. Though such speaker arrangement
results in a high quality and balance of sound in the central region of the listening
area, the sound quality, intensity and balance in the outer regions of the listening
area are generally of a lower standard. It could be argued that the loudspeakers should
be placed in other points and mounted the ceiling of the listening area; this can
result in improved sound properties given that other dispositions can be achieved
; among which placing the speaker so to direct sound in a divergent configuration.
However, to date, sound systems suitable for ceiling mounting of loudspeakers have
not been widely available.
[0003] The present invention provides a multiple ceiling mounting stand for mounting a plurality
of loudspeakers. The stand comprising a plurality of housings mounted on a central
frame, each housing receiving and securely retaining a loudspeaker, whereby the speakers
are mounted in a divergent or radial configuration. The mounting stand is suspended
to ceiling.
[0004] The present invention provide as well single ceiling mounting stands for additional
set of speakers to be mounted separately from one another at different point of the
listening area.
[0005] The invention provides simple and inexpensive apparatus capable of mounting speakers
from an existing sound system to the ceiling.
[0006] The multiple frame (fig. 3) comprises upper rectangular structure 6. The confronting
faces -of the structures 6 have two tapped mounting holes 8 provided on the longitudinal
axis of the longer pair of sides adjacent each comer to receive cylindrical threaded
rods or pipes 10. The rods 10 project perpendicularly to the plane of the structures
6 to define therewith a generally cubical frame. A pair of cylindrical tube 11's are
mounted on each of the rods 10 for pivotal movement about a vertical axis. Supporting
arms 4a,4b project from each tube to meet pivots openings 12a and 12b's. The tubes
are similarly firmed together pairwise by 4 rectangular bar (13) at the opposite ends
in correspondence of each of the 4 corners. The frame may be attached to the ceiling
of a listening area by any appropriate support or bracket.
[0007] Each housing (fig 5) has two component parts. Two similar trays - have bottom reinforcement
struts 21. The free ends 20 receive the free ends 22 of the upper portion in a sliding-fit
engagement to form lower and upper support surfaces of the housing. By adjusting the
position of the two housing portions 23a and 23b the height can be adjusted. The speaker
is firmed between bottom supports 21's of both the components 23,a and 23b and front
tubular frame 25. This housing leaves the front of the speaker free from any parts
crossing its outward face. Clamping 45, screws or other releasable fastening elements
are provided to secure the housing portions. Further the housings may be mounted on
the frame(s) for rotation. (fig 4) where the housings may be releasably fastened on
the frame at preselected angle to the vertical's by means of ends 24a, 24b.
[0008] The multiple mounting stand is secured to the centre of the ceiling of the listening
area. (fig.1)
[0009] Additional single mounting stands (fig.6) are formed by 1 longitudinal bar (17) from
which departs a string or chain (18) that receive the cylindrical rods (10) and cylindrical
tubules (11) and lateral supports 4's whose shape will differ from lateral arms of
the main mounting stand to the extent that the former will be shorter in width where
pivot openings 12a, 12b's are positioned immediately next to cylindrical tubes (11)
such that the line formed by the pivot openings 12a, and 12b and the longitudinal
bar will be perpendicular to the ceiling plane ( see fig.6). Similarly 2 bolts (19)
firm each of the cylindrical tubes (11) from the bottom. The speaker housing is adapted
in the same fashion to the lateral arms 4's as for the main mounting stand. This single
mounting stand hosts a single speaker.
[0010] The single mounting stand is suspended to the ceiling at specific points.( fig 1)
[0011] In order to interpret the text, the following is a detailed description of the invention
with reference to the accompanying drawings in which: Figure 1 is an illustrative
view of a ceiling stand system according to the description consisting of a system
of 6 speakers arranged in a divergent (radial) configuration; Figure 2 is an illustrative
view of the multiple stand shown in Figure 1 with a single housing mounted to the
central frame; Figure 3 is an illustrative view of the multiple frame ; Figure 4 is
an illustrative view of the housing shown in Figure 2; Figures 5 shows front and side
views of the components of the housing; and Figures 6 is an illustrative view of the
single mounting speaker stand.
[0012] To begin assembling of the various components of the ceiling mounting stand , a loudspeaker
50 is placed in element 23a of housing (fig 4) with its front side adjacent the outer
edge , element 23b is mounted and the housing height adjusted according to the size
of the speaker. The housing and the speaker are mounted to the multiple frame or to
the single frame ; end (24a) is fitted in opening 12a) of lateral arms 4a , the vertical
angle adjusted to position, in order to facilitate this process the upper lateral
arm 4b is disjoint from the lower 4a. End ( 24b) fitted in any opening 12 b); clamping
screws (46) are tightened. The housing components is in position and thus secures
the loudspeaker within the housing. The other three loudspeakers are mounted to the
frame in similar fashion. Additionally other speakers on single mounting stands (fig
6) are mounted in the same fashion at specific points (fig.1). The multiple and the
single frames may be permanently or releasably mounted to the ceiling of the listening
area by any appropriate means.
[0013] Of course modification of the preferred embodiment are possible without departing
form the spirit of the invention. For instance the frame could be adapted to receive
any size of loudspeakers , or the multiple frame could be echtagonal to support six
speakers, the various components may be manufactured form metal , aluminum , plastic
or other suitable material.
