However, when changing the mounting position of the array speaker 4 to the frame 1 in the
above-mentioned prior art, the operator first removes all the speaker systems 5, 5, ... one by one,
and then the plates 3, 3. Replace the 3 ... with the desired set of mounting holes 2, 2 ....
At that time, it is necessary to detach the bolts 6, 6,... For fixing the plates 3, 3,. Then, one
speaker system 5, 5,... Is attached again via the plates 3, 3,. It is needless to say that performing
such an operation is troublesome, and this problem becomes noticeable because the assembly
and disassembly of the array speaker 4 is repeated particularly in a temporary installation such
as an event. Moreover, since the weight per one of the speaker systems 5, 5, ... is in the order of
tens of [kg] to several tens [kg], it is necessary to unload such heavy speaker systems 5, 5, ... It is
a very heavy labor and involves danger.
[0005]
Then, an object of this invention is to provide the installation tool for array speakers which can
change the attachment position of the array speaker with respect to a base very easily and safely

rather than before.
[0006]
In order to achieve this object, the present invention provides an installation tool for installing an
array speaker consisting of a combination of an arbitrary number of speaker units, comprising: a
linear first rail portion provided at the base; and the first rail A first mounting portion coupled to
the first rail portion so as to be movable along the portion and to which the array speaker is
attached, and a first fixing means for fixing the first mounting portion to the first rail portion It is
[0007]
That is, in the present invention, the linear, for example, linear, first rail portion is provided on
the base.
Then, the first attachment portion is coupled to the first rail portion, and the array speaker is
attached to the first attachment portion.
That is, the array speaker is attached to the first rail portion via the first attachment portion, and
thus attached to the base. Here, the first attachment portion is movable along the first rail
portion. Then, the first attachment portion is fixed to the first rail portion by the first fixing
means.
[0008]
The first mounting portion may be movable by being slidable along the first rail portion via the
lubricating member.
[0009]
In this case, for example, the first rail portion has a first surface facing the side where the array
speaker is located, and a second surface facing the side opposite to the side where the array
speaker is located.
04-05-2019

The first attachment portion has the third surface and the fourth surface facing each other, and
the first surface and the second surface of the first rail portion are disposed between the third
surface and the fourth surface. It shall be connected to the 1st rail part by pinching in parallel.
Then, assuming that the first surface of the first rail portion faces the third surface of the first
mounting portion, and the second surface of the first rail portion faces the fourth surface of the
first mounting portion, Lubricating members are interposed between the first and third surfaces
facing each other and between the second and fourth surfaces, respectively. In this way, both the
so-called stationary type of attaching the array speaker above the base and the so-called
suspended type of attaching the array speaker below the base relative to the first rail portion The
first mounting portion can slide.
[0010]
Further, in the present invention, a plurality of sets of first attachment portions corresponding to
a plurality of sets of array speakers may be coupled to a common first rail portion. In this way,
multiple sets of array speakers can be attached to the common first rail part via multiple sets of
first attachment parts.
[0011]
Furthermore, in the case where the array speaker is attached to a ceiling, a high place such as a
crane, etc., a linear second rail portion different from the first rail portion is provided on the base,
and the second mounting portion is provided on the second rail portion. It is desirable to attach
the second mounting portion to the elevated portion directly or via some suspension means such
as a wire rope. At this time, if the second mounting portion is movable along the second rail
portion, the mounting position of the second rail portion with respect to the height portion, and
hence the mounting position of the base can be easily changed. This is extremely useful in
adjusting the suspension balance of the array speaker. And, in this case, second fixing means for
fixing the second mounting portion to the second rail portion is provided.
[0012]
As described above, according to the present invention, the first rail portion is provided at the
base portion, and the array speaker is attached to the first rail portion via the first attachment
portion. The first attachment portion is movable along the first rail portion. That is, the array
04-05-2019

both ends of each connection part 34. As shown in FIG. The arm portion 40 is also formed of a
metal square pipe, and when inserted into the connecting portion 34, the connecting portion 34
is difficult to understand in the figure, but is generally known by the quick release pin 42. It is
fixed to Further, wheels 44 are attached to bottom portions near both ends of the connecting
portion 34, respectively.
[0017]
Furthermore, on the side surface of each rail 32, a plurality of through holes 46, 46,... Are bored
at regular intervals, for example, a few [cm] intervals. The through holes 46, 46,... Function as a
first fixing means for fixing the slide fitting 50 to the rail 32 together with a quick release pin 20
described later, which is different from the above. The same through holes 48, 48,... Are formed
on the side surface of the center rail 36.
[0018]
As shown in FIG. 3, the slide fitting 50 has a recess 52 bent and formed, and the rail 32 is
accommodated in the inner space of the recess 52 in order to cover the inner space in a state
where the rail 32 is accommodated. It has a slightly smaller concave cover 54 and a substantially
flat joint 56 firmly held by the housing 52 and the cover 54. Then, the relay fitting 300 described
above is attached to the joint 56, and the line array speaker 200 is attached. The joints 56 have
different shapes among the slide fittings 50, 50,... Forming the same set, for example, as can be
seen from FIG. This is in consideration of convenience when configuring the line array speaker
200 by combining the respective speaker systems 100, 100,... But this is not directly related to
the subject matter of the present invention. The specific description is omitted.
[0019]
Further, a smoother 58 as a lubricating member is provided on the surface of each of the wall
surfaces constituting the internal space of the housing portion 52, which surface is a concave
bottom. As the smoother 58, a hard resin having not only lubricity but also abrasion resistance,
impact resistance, heat resistance and the like is desirable. For example, generally known POM
(polyoxymenthylene) is preferable. A similar smoother 60 is provided on the side of the covering
portion 54 so as to face the smoother 58. As a result, the slide fitting 50 including the housing

portion 52 and the covering portion 54 is coupled to the rail 32 through the smoothers 58 and
60. In other words, the housing portion 52 and the covering portion 54 are attached so as to
sandwich the upper surface (first surface) and the lower surface (second surface) of the rail 32 in
the vertical direction. The outer bottom surface (third surface) of the covering portion 54 is in
contact with the upper surface of the rail 32 via the smoother 60. On the other hand, the inner
bottom surface (fourth surface) of the housing portion 52 is in contact with the lower surface of
the rail 32 via the smoother 58.
[0020]
Further, among the wall surfaces of the housing portion 52, through holes 62 and 62 continuous
with the through holes 46 and 46 formed in the side surface of the rail 30 are formed in the
surface corresponding to the concave side portion. The quick release pin 20 is insertable through
the through holes 62, 46, 46 and 62.
[0021]
Note that one of the surfaces of through-holes 46 and 46 of housing 52 and one surface
corresponding to the concave side of covering 54 are fixed to each other by two sets of bolts 64
and nuts 66. ing. The other surfaces sandwich the joint 56 between them and pass through the
joint 56 and are fixed to each other by another two sets of bolts 68 and nuts 70. In addition,
through holes 70 in the form of, for example, a substantially triangular arrow for indicating the
direction of the slide fitting 50 are consistently bored in the housing portion 52, the covering
portion 54, and the joint 56.
[0022]
As described above, according to the installation tool 10 of the present embodiment, the straight
rails 32 and 32 are provided on the frame 30 as the base, and the rails 32 and 32 are provided
with the slide fittings 50, 50, ... are combined. And since each slide fitting 50 is connected to the
rail 32 via the smuters 58 and 60, it can slide along the rail 32 concerned. On the other hand, the
slide fitting 50 can be fixed by the quick release pin 20 at any of the positions where the through
holes 46, 46,... On the rail 32 are formed. Then, the line array speaker 200 is attached to these
slide fittings 50, 50,. That is, as shown in FIG. 4, the line array speaker 200 is attached to the
rails 32 and 32 via the slide fittings 50, 50,... And, in turn, attached to the frame 10. It can be
04-05-2019
7
moved (manually) along the rails 32 and 32. And, at any position where the through holes 46,
46,... Are bored, it can be arbitrarily fixed. Therefore, when changing the mounting position of the
array speaker 4 to the frame 1, it is necessary to unload all the speaker systems 5, 5,... And
reattach each plate 3, 3,. The mounting position of the line array speaker 200 with respect to the
frame 30 can be changed extremely easily and safely as compared with the above-described
prior art.
[0023]
In the installation tool 10 of the present embodiment, a plurality of sets of slide fittings 50, 50,...
Can be attached to the same rails 32 and 32. In this way, for example, as shown in FIG. 5, plural
sets (two sets in the same figure) of line array speakers 200 and 200 can be attached to the
installation tool 10, which is very convenient at the time of transportation or the like. In addition,
it is possible to use one set of line array speakers 200 which is relatively large (that is, the
number of combinations of the speaker systems 100, 100,... Is relatively large) separated into
several and transported. Furthermore, it can be used to carry other types of speakers than the
line array speaker 200.
[0024]
Moreover, the installation tool 10 of this embodiment can be used also as what is called a
hanging type | mold, as shown in FIG. In this case, slide metal fittings 80 and 80 as a pair of
second mounting parts similar to those described above are attached to the center rail 36. Then,
appropriate suspension means such as a wire rope or the like hanging from a ceiling or a high
part such as a crane (not shown) is connected to the slide fittings 80 and 80. In this manner, the
portion to which the suspension means is coupled is also coupled to the center rail 36 via the
similar slide fittings 80 and 80 and thus coupled to the installation tool 10, thereby the
installation tool The coupling position of the hanging means with respect to 10 can be easily
changed. This is extremely useful when, for example, adjusting the suspension balance of the line
array speaker 200. Moreover, since the center rail 36 for suspension is provided separately from
the other rails 32 and 32, the degree of freedom of the balance adjustment and the like is
improved. In order to fix each of the speaker fittings 80 to the center rail 36, a quick release pin
90 as a second fixing means as described above is used. Of course, the levels 32 and 32 can also
be used for suspension.

As described above, the upper surface and the lower surface of the rail 32 can be used as the
slide metal fitting 50 via the smoothers 58 and 60 as described above. It is because it is set as
the structure inserted | pinched from the upper and lower sides by the accommodating part 52
and the coating | coated part 54. The same applies to the relationship between the center rail 36
and the slide fitting 80.
[0026]
In the present embodiment, each of the rails 32 and 32 and the center rail 36 are straight, but it
may be an arc, an arch, an S-shape, or the like.
[0027]
Moreover, although the smoothers 58 and 60 as a lubricating member were provided in the slide
metal fitting 50 side, you may provide this on the rail 32 side.
In particular, if the lubricating members are provided on both sides, the coefficient of friction
between them is further reduced, the slidability is further improved, and the workability is
improved. The same applies to the relationship between the center rail 36 and the slide fitting
80.
[0028]
And in this embodiment, although hard resin, such as POM, was mentioned as an example as a
lubricious member, you may employ | adopt other than this. At the extreme, a roller, a high
viscosity lubricant or the like may be employed.
