Speaker cabinet having a device for mechanically connecting to another cabinet and / or a device
for adjusting the angle between the cabinets
[0001]
The present invention relates to a loudspeaker cabinet comprising a device for mechanically
connecting to another cabinet and / or a device for adjusting the angle between the cabinets.
[0002]
Combining specialized acoustic system cabinets in tandem (or “linear array”) has been
commonplace for over a decade.
03-05-2019

Such a combination can be constituted by dozens of cabinets each exceeding 50 kg.
[0003]
Therefore, the Rigging system has two categories: a frame (or "bumper") that connects the upper
cabinet to the hoisting motor and mechanical components that connect the cabinets to each
other. It has been proposed to be divided into
[0004]
Many of the inter-cabinet mounting systems have the following features.
[0005]
If multiple cabinets reach their final angle by gravity, the cabinets are mounted using a tension
mounting method.
Alternatively, if the return force applied to the bottom of the assembly causes each cabinet to be
at a final angle, the cabinets are mounted using a compression mounting method.
[0006]
Since the inter-cabinet mounting system is a four-point system, it is over-stressed in the
definition of one plane so that the fourth point is always difficult to connect.
[0007]
Inter-cabinet mounting systems use multiple ball locks or quick release pins, so the tolerance of
the holes to receive these ball locks must be very closely defined (if the holes are too small, the
pins will If the hole is too large, the pin will not be held).
[0008]
The pins provide both connection between cabinets and angle adjustment between cabinets
(generally the angle is adjusted between 0 ° and 10 °), but the angle adjustment must be
identical on each side of the cabinet Make the system and its assembly more complicated.
03-05-2019

[0009]
The ball lock is a part separated from the cabinet and is easy to lose.
[0010]
When the cabinets are mounted by tension, the method of mounting the cabinets includes the
meaning of manually lifting the back of the cabinets in order to insert the ball locks into the
holes corresponding to the required angle values between the cabinets, The above problems
become serious.
[0011]
As a result, the current systems described above are complex to assemble and require at least a
few skilled technicians.
Such an assembly would require even more valuable time if performed for a concert to be held
the same evening.
[0012]
Further, solutions described in Patent Document 1, Patent Document 2 and Patent Document 3
are known.
[0013]
U.S. Patent No. 7,328,769 U.S. Patent No. 7,298,860 U.S. Patent No. 7,634,100
[0014]
In this regard, the invention provides a speaker cabinet comprising a device for mechanically
connecting to another speaker cabinet, the connecting device comprising: translational actuation
control in a first direction and the first direction. A speaker cabinet is proposed, characterized in
that it comprises a mechanism for converting the translational movement of at least one first
latch in different second directions.
[0015]
03-05-2019

The actuation control can thus be arranged, in particular, in an easily accessible location on the
cabinet.
Likewise, the action that the operator performs to provide actuation control is therefore, in fact,
desired (and not necessarily the direction of movement of the latch).
[0016]
Further, the conversion mechanism can convert the translational movement into the translational
movement of the second latch, thereby enabling driving of the two lock points from a single
movement control.
[0017]
The translational movement of the second latch is, for example, in a second direction opposite to
the translational movement of the first latch, allowing simultaneous connection of both sides of
the cabinet by means of the above-mentioned actuation control.
[0018]
The conversion mechanism includes a cam driven by the operation control.
Such a cam allows not only to interlock the up and down movement arbitrarily but also to
perform a turn around, in particular by selecting an appropriate cam path.
[0019]
The cam defines a cam path or the like suitable for guiding a pin rigidly fixed to the latch.
Furthermore, it is possible to provide a cam path comprising a recess in which the pin is fixed by
means of a spring.
03-05-2019
4
Thus, the combination of the cam and the spring makes it possible to lock the mechanism in a
certain direction.
[0020]
As in the embodiments described below, the first direction is, for example, essentially
perpendicular to the second direction, which makes it a particularly practical arrangement.
However, as an alternative, it is possible to form a different (non-zero) angle than the right angle
between the first direction and the second direction.
[0021]
The above operation can be performed by the handle.
Furthermore, a mechanism can be provided for automatically locking the handle at a position
corresponding to the connected position of the latch.
As soon as the cabinet is connected, the handle is then automatically locked (ie, for example,
when the operator moves the handle to a position where the cabinet is connected to another
cabinet by a latch, operation on the locking mechanism Locked without the action of the person).
Conversely, unlocking requires specific action by the operator on the locking mechanism, as
described below, thereby providing additional security.
[0022]
The invention further provides a loudspeaker cabinet comprising a device for adjusting the angle
formed between a cabinet and another cabinet, if necessary separately from the above.
03-05-2019

The speaker cabinet comprises an element for adjusting the angle by its length in the operative
position, the length of the element being, for example, the position of the rotating component
which can be adjusted by the user, generally by rotation of the rotating component by the user. It
is determined according to
The use of such a rotating component considerably simplifies the adjustment of the length of said
elements and consequently also simplifies the adjustment of the angles between the cabinets.
Thus, the user can rotate the rotating component to the desired position and determine the
length of the element at the operating position.
[0023]
The element may, for example, be a piston comprising a rod slidably mounted in the body, and
the rotational component may be a gear rotatably mounted about the main axis of the piston.
[0024]
The cabinet is then rigidly fixed, for example to the main body, while at the same time another
cabinet is for example (optional), so that adjustment of the length between the cabinets is
possible by adjusting the length of the piston in the operating position, as described below.
Attached to the rod using a ball lock).
[0025]
For example, as in the embodiments described below, the piston can be in compression in the
operating position.
[0026]
As another possibility, as in the variant described at the end of the following description, the
piston can also be in tension in the operating position.
[0027]
In addition, a device can be provided which locks the rod in the position of maximum extension
relative to the body, which allows several cabinets to be stacked on the dolly while keeping it
horizontal for transport. Do.
03-05-2019

[0028]
Furthermore, a device can be provided which locks the rod in the storage position in the body, so
that the piston can be stored in the body within the height of the cabinet.
[0029]
The above-mentioned angle adjustment can be made about a retractable axis provided in the
cabinet for connection with another cabinet.
[0030]
In this regard, as described above, a mechanism can be provided to convert translational
movement in a first direction into translational movement of at least one first latch in a second
direction different from the first direction.
Additionally, the retractable shaft can have the first latch.
[0031]
This conversion mechanism can optionally incorporate one or more of the above mentioned
optional features into the conversion mechanism proposed by the present invention.
[0032]
Additional features and advantages of the present invention will become apparent upon
consideration of the following description and upon reference to the accompanying drawings.

[0034]
1 and 2 show a loudspeaker cabinet 2 comprising three devices, in particular the following,
which are mechanically linked to one another.
03-05-2019
8
[0035]
The first device is stored under the cabinet, and the translational movement in the depth
direction of the handle 6 disposed at the back of the cabinet is in the lateral movement driving
the side latches (reference numeral 5 in FIG. 3). It is a “T-shaped” assembly 4 equipped with a
converting mechanism.
[0036]
The second device, here a single piston, is a piston 8 which makes a back connection with
another cabinet as well as an angular adjustment between the cabinet 2 and another cabinet.
The upper portion of the piston is anchored in the cabinet and the lower portion of the piston is
connected to the lower cabinet by a single ball lock.
The gear 10 is rotatably mounted around the axis of the piston 8 and the position of the gear 10
is marked by, for example, a letter, and the length of the piston (described later, as described
below) It is possible to pre-adjust the length when the cabinet is assembled, as a result of which it
is possible to pre-adjust the angle between the cabinets.
[0037]
The third device is a metal bumper 12 that ensures the rigidity of the assembly, such as metal
continuity above and below (for gravity acting on narrow angles) and metal continuity before and
after (for power transfer for wide angle) is there.
[0038]
Besides each of the above structural assemblies, the cabinet 2 comprises an outer wall, ie
specifically adapted to receive the piston 8 in the upper wall 14, the lower wall 20, the side wall
22 and the indentation. A rear wall 24 is provided.
[0039]
The front of the cabinet 2 itself is closed by a grid 26 to emit sound waves.
03-05-2019
9
[0040]
The upper wall 14 comprises a front portion 18 which is essentially flat and a rear portion 16
which is essentially flat and slightly inclined with respect to the front portion 18.
[0041]
As shown in the example, the front part 18 is generally horizontal (ie substantially parallel to the
direction of the acoustic radiation of the cabinets) and the rear part 16 is inclined with a
maximum half angle assumed for the angle between the cabinets There is.
[0042]
In the front part of the rear part 16 of the top wall 14, two lugs 28 extend on the top wall 14
which are respectively located at the lateral ends of the top wall 14 .
[0043]
As described further below, each protrusion 28 originates from the bumper 12 (i.e., is
mechanically connected to the bumper 12).
Also, the projections 28 are adapted to receive each latch of another cabinet designed, for
example, like the cabinet of FIG. 1, said another cabinet comprising between two projections 28,
in particular of each projection 28. It is placed in contact with the cabinet 2 at the position of the
hinge line C extending between the centers of the holes.
The projections are attached at the location of the junction between the front part 18 and the
rear part 16.
[0044]
The lower wall 20 is also essentially flat (and here approximately horizontal) with the front part
21 and essentially flat (and again by the maximum half-angle assumed for the angle between the
cabinets B) a rear part 19 slightly inclined with respect to the front part 21;
[0045]
03-05-2019
10
The T-shaped assembly 4 extends such that the lower surface of the T-shaped assembly 4
extends in the plane of the rear part 19 of the lower wall 20, ie beyond the plane defined by the
rear part 19 of the lower wall 20. It is mounted on the cabinet 2, in particular on the rear part 19
of the lower wall 20, so as not to be present.
It should be noted that the T-assembly 4 (in particular its transverse part 32 described below)
forms a junction between the front part 21 and the rear part 19.
[0046]
As described in more detail below, the T-shaped assembly 4 comprises a shaft portion 30 and a
transverse shaft portion 32.
The shaft portion 30 extends essentially in the direction of the acoustic radiation between the
handle 6 and the transverse shaft portion 32, although on the plane of the rear portion 19 of the
lower wall 20.
[0047]
It should be noted that the handle 6 preferably extends here to the rear end of the lower wall 20
so that it can be easily manipulated from the rear of the cabinet.
[0048]
The transverse shaft portion 32 extends perpendicularly to the shaft portion 30 over
substantially the entire width of the rear portion 19 of the lower wall 20 and carries removable
latches at each end thereof, as described below.
[0049]
In addition, the T-shaped assembly 4 has its lower part so that each end of its transverse part 32
supporting the latch 5 is arranged respectively in the position of two parallel tabs 34, 36 from
the bumper 12. It is arranged at the position of the wall 20.
03-05-2019
11
[0050]
The tabs 34 and 36 each have a hole 38 in which the adjacent latch 5 (supported by the
transverse shaft portion 32 of the T-shaped assembly 4) can be locked in the deployed position.
[0051]
FIG. 3 shows the connection between the two cabinets using the cabinet tabs 34, the tabs 36 and
the T-assembly 4 and the projections 28 'of another cabinet.
[0052]
FIG. 3 shows that once the two cabinets are placed in contact with each other (ie, one hinge line
C of the cabinets is placed along the transverse portion 32 of the T assembly 4 of another
cabinet) ), The orifices of the projections 28 'are aligned with the respective orifices 38 of
another cabinet tab 34, tab 36, so that the latch 5 can be moved to the deployed position, as
described below Is shown.
The placement position of the latch 5 is the position of the orifice 38 of the cabinet of the latch 5,
and as a result, the latch 5 passes through the orifice of the projection 28 '.
[0053]
Such an assembly takes place at each of the lateral ends of the two cabinet assemblies, whereby
the two cabinets connect two latches 5 defined above as hinge line C in this case Are connected
to each other at the position of the
[0054]
FIG. 4 shows a bare bumper (i.e. a bumper without a wall of the cabinet) to which the piston 8 is
attached.
[0055]
The bumper 12 is provided with a cross member 40 as a main part, and the cross member 40
supports at its center a bracket 42 adapted to rotatably support the upper portion of the piston
8.
03-05-2019
12
[0056]
The cross member 40 is attached at the end of the bumper on the side portion 44 of the bumper
12.
[0057]
The side portions 44 basically extend essentially perpendicularly to the general direction of the
cross member 40, since they respectively extend in a plane substantially corresponding to the
plane of the corresponding side wall 22.
[0058]
The side portions 44 of the bumper 12 are each provided with a triangular structure 46.
The triangular structure 46 receives the plurality of fasteners of the cross member 40 at the apex
of the triangle formed thereby, and the sides 50 of the triangular structure 46 which are opposite
sides of the apex 48 have the projections 28 as the tabs 34, 36 described above. Mechanically
connected to
[0059]
The respective positions between the inter-cabinet connection assemblies (protrusions 28, tabs
34, tabs 36 described above) allow the sides 50 of the triangular structure 46 to be made, for
example, in the form of two parallel rails as shown in FIG. Can be reinforced.
[0060]
5 and 6, as described above, the movement of the handle 6 in the depth direction of the cabinet
(ie in the general direction of the radiation of the cabinet) to the respective lateral movement of
the latch 5, ie Here, in particular, it is possible to convert the movement perpendicular to the
movement of the handle 6 in the plane of the T-assembly 4 (ie the plane formed by the rear part
of the lower wall 20 of the cabinet 2 as described above) 5 shows a cross section of the rod
connection mechanism of the T-shaped assembly 4;
[0061]
03-05-2019
13
FIG. 5 shows the mechanism when the handle 6 is in the rearmost position and thereby the latch
5 is respectively stored.
6 on the other hand, as described above with reference to FIG. 3, shows the mechanism in which
the handle 6 is in the foremost position and thereby the latch 5 can be fully positioned and lock
the assembly of the two cabinets It shows.
[0062]
The mechanism comprises an axial control rod 54, which is positioned between the handle 6 and
the cam 60 and guided in translation along the rod's own axis by means of bearings 62.
[0063]
Thus, the axial control rod 54 enables driving the cam 60, which will be described in more detail
below, in the same translational motion as that given to the handle 6 by the user.
[0064]
The mechanism also comprises two lateral control rods 56, 58 which each connect the cam 60 to
the latch 5.
The lateral control rods 56, 58 are each guided in translation by means of bearings 64 in the
direction of movement of the respective latch 5, ie here perpendicular to the axial control rod 54.
[0065]
Further, a spring 66 is mounted on each of the lateral control rods 56, 58 between the cam 60
and the bearing 64.
[0066]
The cam 60 comprises two cam paths 68 each cooperating with a pin 70 rigidly fixed to the
lateral control rods 56,58.
03-05-2019
14
The cam paths 68 each comprise a first part, here formed by a plane inclined at 45 °, and a
second part with a slight depression in the storage direction of the corresponding lateral control
rods 56,58.
[0067]
As mentioned above, FIG. 5 shows the mechanism in which the latches 5 are each in the stored
(or returned) position within the T-shaped assembly 4.
[0068]
The user then pushes the handle along the arrow U shown in FIG. 5 to move the axial control rod
54, thereby translating the cam 60 in translation in the same direction.
[0069]
In particular, the movement of the cam 60 by displacement of the pin 70 in the cam path 68,
here a 45 ° plane, causes the pin 70 to move, whereby the lateral control rods 56, 58 along the
axes of the control rods and respectively In the direction of placement of the latch 5 of the Tassembly 4.
[0070]
Note that this movement involves the compression of the spring 66.
[0071]
The above-mentioned movement continues until the position where the pin 70 forms the recess
of the cam path 68, as shown in the detail view of FIG. 7B, in which position the pin 70 Fixed by
the compression effect of the spring 66).
[0072]
Thus, as shown in FIG. 6, the arrangement position of the latch 5 is realized.
This position is stabilized by the pins 70 fixed in each recess.
03-05-2019
15
[0073]
In order to provide further safety, a mechanism is used here which locks the handle 6 in a
position corresponding to the arranged position of the latch 5.
This mechanism is shown in FIG. 7A.
[0074]
The mechanism comprises a rod 104 which is guided by the brace 108 and in contact with the
handle 6 by means of a spring 102 (i.e. here downwards).
[0075]
The top of the rod 104 supports the gripping device 106.
[0076]
The lower portion of the rod 104 rests on the upper surface of the handle 6 at the position
shown in FIG.
[0077]
As described above, when the handle 6 is pushed forward and reaches the disposition position of
the latch 5, the rod is aligned with the hole 110 provided in the handle 6, and is automatically
inserted into the hole 110, Lock the handle 6 in its forwardmost position.
[0078]
However, in addition to exerting a force on the spring 66 as already described, returning the
handle 6 to its rearmost position allows the user to remove the rod from the hole 110 (using the
gripping device 106) It is necessary to lift the rod 104 and thereby unlock the handle 6.
[0079]
As already described with reference to FIG. 3, the latch 5 locks the two cabinets to each other in
the arrangement position, and the rotation axis between the cabinets corresponding to the axis
03-05-2019
16
connecting the latches 5 is defined. To be done.
[0080]
It should be noted that ultimately the force holding the pin 70 in the recess of the cam path 68 is
when the user manipulates the handle 6 rearward (ie to return from the position shown in FIG. 6
to the position shown in FIG. 5) The pins 70 are designed to come out of the corresponding
recesses.
[0081]
FIGS. 8 and 9 show the piston 8 in the adjustment or transfer position, which corresponds to the
maximum extension position of the piston.
[0082]
The piston 8 comprises an upper mounting site 72 and a lower mounting site 74.
[0083]
The upper mounting portion 72 is rigidly fixed to the body 78 of the piston and is here integrally
formed with a casing 76 rigidly fixed to the body while enclosing the body 78.
[0084]
The body 78 forms a female portion of the piston 8 while the male portion is formed by a rod 80
slidably mounted within the body 78 and having a lower mounting site 74.
[0085]
The control lever 82 is attached to the side wall of the casing 76 and also comprises a latch 86.
The latch 86 is slidably mounted perpendicularly to the axis of the piston 8 and is always
directed to the axis of the piston 8 by means of a spring 84 mounted on the control lever 82.
[0086]
It is noted that the latch 86 is slidably mounted not only through the appropriate opening of the
03-05-2019
17
casing (to which the control lever 82 is attached) but also through the cylindrical bore 79 formed
in the body 78.
[0087]
By acting against the force generated by the spring 84, the user can manipulate the latch 86 to
various positions along the axis of the piston 8 as described below.
[0088]
In the position shown in FIGS. 8 and 9, the latch 86 (under the influence of the spring 84) is
formed on the circumference of the rod 80 at the upper part of the rod 80 (ie the part located on
the upper attachment site 72 side). Into the annular recess 88 that is
[0089]
Thus, the rod 80 is at a predefined longitudinal position relative to the body 78, which position is
determined by the relative positioning of the latch 86 and the annular recess 88.
This position corresponds to the maximum extension use position of the piston 8 since the
annular recess 88 is located in the upper part of the rod 80.
[0090]
In this position, the user can rotate the gear 10 rigidly fixed to the rod 80 (especially rotatably
fixed about the axis of the piston 8) to the desired position, for example marked by a
predetermined character.
[0091]
The user then adjusts the angular position of the rod 80 about an axis, thereby adjusting in
particular the angular position with respect to the body 78 (which is rotatably fixed relative to
the cabinet).
At this point, the rod 80 and the gear 10 rigidly fixed to each other can rotate and move relative
03-05-2019
18
to the lower attachment portion 74.
[0092]
Starting from the position shown in FIG. 9, the user can pull on the control lever 82 to bring the
latch 86 out of the recess 88, releasing the translational movement of the rod 80 in the body 78.
[0093]
This movement is possible until the pin 90 carried by the rod 80 engages the surface of the cross
section 92 provided on the body 78, as will be described in more detail here.
[0094]
The length of the piston in compression is such that, during the compression operation of the
piston after assembly of the cabinet described below, the pin 90 of the rod 80 is in the body 78,
for example the position shown in FIGS. 11 and 12 It is determined by the longitudinal position
on the cross section 92.
[0095]
Due to the particular shape of the cross section 92 (see in particular the perspective view of the
body 78 of FIG. 13), the longitudinal position of the rod 80 where the pin contacts the cross
section 92 is fixed by the relative angular position of the body 78 and the rod 80 The position is
pre-adjusted by the user, as described above with particular reference to FIGS. 8 and 9.
[0096]
FIG. 14 shows the piston 8 in a storage (or storage) position that results in a minimum volume, as
further shown in FIGS. 1 and 2.
[0097]
The rod 80 comprises a cylindrical bore 94 (which is perpendicular to the main axis of the rod
80), which bores the rod 80 in the body 78, in particular the rod 80 relative to the body 78 The
latch 86 is positioned at the same height as the cylindrical bore 79 through which the latch 86
passes, as described above, when it is fully retracted to its angular position.
[0098]
03-05-2019
19
Thus, when the user, for example, places the gear 10 in a suitable position appropriately labeled
for this purpose and pushes the rod 80 into the body 78 (for example by gripping the lower
attachment site 74 and lifting it) The latch 86, under the pressure of the spring 84, enters the
cylindrical bore 94 of the rod 80, thereby longitudinally securing the rod 80 in the body 78.
The said fixed position will define the above-mentioned storage fixed position.
[0099]
The procedure for installing a set of cabinets in accordance with the teachings of the present
invention will now be described.
[0100]
FIG. 15 shows a first cabinet C1 connected to a bumper, which itself is connected to two hoisting
motors.
[0101]
Figures 16 and 17 show how the second cabinet C2 is connected to the first cabinet C1.
[0102]
The procedure for combining these two cabinets is, for example, as follows.
[0103]
The first cabinet C1 is prepared by positioning the piston 8 'of this cabinet in the adjustment
position (shown in FIGS. 8 and 9) and adjusting the gear 10' in the selected position.
[0104]
The ball lock 73 "attached to the upper attachment site 72" of the piston 8 "of the second cabinet
C2 is removed.
[0105]
The second cabinet C2 is, as described above, aligned by aligning both cabinets (ie by aligning
the hinge line C of the second cabinet C2 with the axis of the latch of the first cabinet C1) the

first cabinet C1 Located below.
[0106]
The handle 6 'of the connection mechanism of the first cabinet C1 is moved forward so that the
cabinet C1 and the cabinet C2 can be coupled to one another as already described with reference
to FIG.
[0107]
The ball lock 73 '' is mounted through the upper mounting portion 72 '' of the piston 8 '' of the
second cabinet C2 and the lower mounting portion 74 'of the piston 8' of the first cabinet C1.
[0108]
The new assembly constructed as described above is lifted using a hoist motor as shown in FIG.
18 to receive the next cabinet.
[0109]
The above procedure is repeated for each of the added cabinets so as to obtain a plurality of
combined cabinets as shown in FIG.
[0110]
As shown in FIG. 20, the rear lift motor connected to the last cabinet (ie, the bottom cabinet) of
the plurality of cabinets compresses the assembly such that the piston is compressed, thereby
causing the piston to The operating position is reached, and the angles between the cabinets
adopt the final angular value of each cabinet determined by the adjustment of the gear.
[0111]
The system is then lifted to its final height.
[0112]
Furthermore, this so-called "compression" mounting method has the advantage of eliminating the
need to lift the back of the continuous cabinet to adjust the angle.

That is, the cabinet stands vertically and the hoist motor provides the final configuration of the
assembly.
[0113]
The removal procedure is performed in the reverse order of the installation procedure, the
difference being that when disconnecting the cabinet, it requires specific manipulation by the
operator on the locking mechanism as described above.
[0114]
Also, the angle adjustment system proposed by the present invention is equally applicable when
a tension rigging method is used.
However, in this case, as shown in FIGS. 21 and 22, the angular position of the rod (adjusted
using the gear as described above) is the length of the compressed piston (as in the above
embodiment) The piston will be used, which determines the length of the extended piston.
[0115]
Furthermore, each of the above examples is merely a possible embodiment of the present
invention and is not limiting.
