Field of the Invention
[0001] The present invention concerns the entertainment sector and especially concerns a
professional device for special effects and, specifically, for shooting confetti,
streamers or other materials.
State of the art
[0002] Professional devices to create special effects at events such as concerts, parties,
shows, events, etc., both outdoors and in theaters, locations, arenas or the like,
are widely used in the entertainment sector.
[0003] In particular, the so-named shooting machines, or confetti shooting canons, that
allow to shoot confetti, streamers, or other items made of fabric or anyhow of light
material to create spectacular and unique effects, are known.
[0004] These machines use compressed air to shoot confetti and the like towards the desired
direction at high height, so that to cover a wide area. The machine can continuously
shoot a flow of material for a time determined by the time necessary for emptying
the air from the tank.
[0005] The machines according to the known art essentially consist of shooting tube, to
be filled with materials to be shot which can be in the form of confetti and the like,
combined with a valve and preset to be able to be connected to an outer cannister
containing a pressurized gas, such as CO
2, so that, when the valve is open, the gas can flow in the tube, thus causing the
shot. However, this configuration allows to carry out a single shot.
[0006] In particular, at big events, such as for example concerts in stadiums or evens in
large environments or outdoors, a multiplicity of such machines, which must be prearranged
before the event itself, often also on scaffolds or in places that are difficult to
access once the event has started, are used. The machines are then controlled remotely
to make the shot.
[0007] Whenever the possibility to make more than one shot of confetti or the like is required,
also at different times, the presence of a lot of personnel is necessary for refilling
the various shooting tubes; in addition, despite this, it is not always then possible
to refill the machines that cannot be reached during the event.
[0008] The European patent application
EP 1 604 166 A1 concerns a device for projecting light materials, such as confetti or the like and/or
emulsions such as foam, snow or the like. The device comprising a container containing
the materials to be projected is connected by means of a vacuum device, such as an
air amplification transducer, for example supplied with compressed air from compressed
air cylinders, equipped with a safety valve. The containers containing the light materials
are connected at the rear end of the transducer, to which a negative pressure is applied,
while a positive pressure is applied at the opposite front end of said transducer
to which a tubular element for ejecting outwardly is connected. Thus, the device comprises
a portion for distributing the compressed air, comprising at least one inlet connected
to the outlet of the safety valve and at least two outlets, a first outlet being connected
to the compressed air inlet of the air amplification transducer and a second so-named
automatic sealing outlet, i.e. an outlet that is sealed when no connecting means is
connected to said outlet and that is open when a connecting means is connected thereto,
adapted to be connected to the inlet of a distributing element of a second device
for projecting light material. Thus, such a device requires means for sucking the
material contained in an appropriate container and means to cause the ejection through
the distributing element.
[0009] Object of the document
WO 2015/034380 is a system for ejecting confetti and/or streamers, intended for the multiple ejection
of streamers and confetti with the use of pressurized air, having a single shooting
tube combined with a cartridge belt. Thus, such a device is not adapted to carry out
several shots simultaneously and is very complex and costly since it must comprise
means for bringing a cartridge at the shooting tube from time to time.
[0010] Both of the devices of the known art are particularly complex and bulky to be installed,
thus being inappropriate for installations of the type described above, as well as
costly to make.
Summary of the Invention
[0011] An object of the present invention is to provide a device for shooting confetti,
streamers, or other similar items that overcomes the drawbacks of the known art.
[0012] Another object of the present invention is to provide a solution that allows to reduce
the number of devices needed at an event and the amount of personnel needed to manage
them.
[0013] A further object is to provide a device that allows to easily make more than one
shot, whether simultaneously, at different times, and also at times close to each
other.
[0014] Another object is to provide a device of contained bulkiness, which can also be installed
on pylons and scaffolds.
[0015] Still a further object is to suggest a device that is simple to make and that requires
a limited amount of components, with reduced costs with respect to the devices of
the known art.
[0016] These and further objects are achieved by a device for shooting confetti, streamers
and the like according to claim 1, comprising a tank to be filled with a pressurized
gas through a specific inlet and means to establish an independent fluid connection
between the tank and each of the at least two shooting tubes containing confetti,
streamers or other similar items, said means for establishing a fluid connection being
combined with the tank. The wording shooting tubes refers to tubular elements prearranged
to be filled with the material to be shot.
[0017] The presence of a tank provided with connecting means to be combined with at least
two distinct shooting tubes, each combined with the tank so that to be able to receive
a flow of compressed gas independently of the other, allows to make at least two shots
of confetti at different times, without having to refill the shooting tubes. In fact,
it is sufficient to prearrange and combine the at least two shooting tubes, appropriately
filled with the desired material, with the tank to be able to make two shots simultaneously,
or in sequence, or at different times during the same event. The shooting tubes are
thus connected with the tank in parallel to one another so that to be completely independent
one of the other. For this reason, the present invention does not provide any serial
connection of the shooting tubes connected to a same tank.
[0018] Advantageously, each shooting tube is combined to the tank by means of a respective
outlet; in other words, the tank is provided with as many outlets as the shooting
tubes that can be combined with the device. The number of shooting tubes establishes
the maximum number of shots that can be made without having to make any refill.
[0019] Preferably, the compressed gas present inside the tank is channeled in each of said
tubes through valves.
[0020] Such valves can be individually combined with each shooting tube and channel the
air therein by means of a respective outlet.
[0021] Preferably, the valves can be electrovalves, or pneumatic control valves.
[0022] Advantageously, the device is provided with means for controlling it remotely so
that to be able to cause the shots remotely. The shots can be caused manually, by
sending a relative activation signal to each specific shooting tube, for example by
means of an electronic device such as a remote control. In alternative on in addition,
the sequence and the times of the shots can be set before the event, by acting on
the timing means combined with the single valves, or preferably with the device itself.
[0023] Thus, in a preferred solution, the device comprises a programmable control unit to
manage the opening of the valves and consequently the shots.
[0024] Advantageously, in order to reduce the bulkiness of the device when unused and to
facilitate the refilling of the shooting tubes, each shooting tube is removably combined
with the device, preferably by screwing and with the aid of a quick coupling. A safe
and stable connection is thus formed, but it is also at the same time possible to
quickly unlock and lock each shooting tube from/to the tank.
[0025] Preferably, it is possible to vary the shooting angle, i.e. the angle that the shooting
tube forms with the horizontal plane, by simply rotating the tank with respect to
a containment body to which it is fastened. In order to allow this operation, the
device comprises at least two brackets to fasten the tank to the containment body
and locking elements to hold the tank in the desired position. This way, it is possible
to vary the range, the inclination and the maximum height of the shot according to
necessity.
[0026] In a particularly preferred solution, the tank comprises as many tank portions as
the outlets combined with each other so that to be rotatable one with respect to the
other in order to allow to direct the shots in different ways. From the moment that
the tank contains a compressed gas, such tank portions are combined with each other
fluid-tightly.
[0027] Advantageously, the tank is kept at a pressure of at least 4 bars, preferably of
at least 8 bars, so that to ensure the pressure needed to make the shots.
[0028] Advantageously, so that not to have to increase the size of the tank and thus of
the device, means for refilling the compressed gas, comprising a tube for connecting
to a compressed air source or at least one device for containing a compressed gas
such as a CO
2 cannister, provided with a pressure reducer to deliver the gas in the tank, can be
combined with the gas supply inlet, once the tank is filled with compressed gas, so
that to refill the tank once the gas present therein has run out.
[0029] In alternative or in addition, a single tank of greater capacity internally subdivided
so that to provide the amount of compressed gas needed at the pressure necessary to
make the shot to each shooting tube, or more tanks each combined with a relative shooting
tube, can be prearranged.
[0030] Advantageously, whenever the device is prearranged to make two shots simultaneously,
a single tank of a capacity sufficient for making both shots can be prearranged, preferably
a single tank of a capacity of 40 liters of compressed gas at a pressure of 8 bars.
Description of the drawings
[0031] Further characteristics and advantages of the invention will be better highlighted
by the review of the following detailed description of a preferred, but not exclusive,
embodiment illustrated by way of example and without limitations, with the aid of
the accompanying drawings, in which:
figure 1 shows a perspective view of an embodiment of a device for shooting confetti,
streamers and the like according to the present invention;
figure 2 shows a side view of part of the device;
figure 3 shows a view from above of the device of figure 1, before its assembly; and
figure 4 shows the device of figure 1 in an unused condition.
Detailed description of the invention
[0032] With reference to the figures, the device 1 for shooting confetti, streamers and
the like according to the present invention is depicted. For brevity, the following
description will refer only to the confetti, but this does not exclude the fact that
the device is also appropriate for shooting streamers or other items made of fabric,
paper or anyhow of materials of different shapes and sizes.
[0033] Specifically, the device comprises a containment body 2 with which a tank 3 for a
compressed gas is combined, having an inlet 4 for connecting to an outer apparatus
for its filling. Usually, the tank is filled with compressed air by means of a compressor.
In alternative, the device can be filled with CO
2 by means of cannisters with pressure reducer, which can be housed inside the containment
body to easily make the refills and without requiring a connection to an electric
power supply.
[0034] The tank is at a pressure of at least 4 bars, preferably of at least 8 bars. The
air pressure value is very important since it determines the shooting range of confetti.
A pressure gage 5 is thus combined with the tank to monitor the pressure therein.
A relief valve 4' can also be combined with the tank to cause an outflow of pressurized
gas whenever the pressure value detected by the pressure gage is greater than a maximum
predefined value.
[0035] The tank comprises at least two outlets 6 independent of each other, each for connecting
to a respective shooting tube 7 for ejecting the confetti previously inserted therein.
Advantageously, each shooting tube is removably combined with the respective outlet
through hooking means 6', preferably by screwing, by quick coupling.
[0036] A raising core 8 arranged in the tube so that to block up each tube in proximity
of the outlet, must be inserted inside each shooting tube so that to improve the operations
of the device. Once filled with the material, the free end 9 of the tube can be closed
with a pressure cap 10, both to properly maintain the material inside the tube and
to pressurize the tube during the shot, for a greater shooting effect.
[0037] Preferably, the tank is combined with the containment body so that to be able to
be rotated on its longitudinal axis A. This rotation allows to change the angle of
each shooting tube with respect to the horizontal direction, so that to be able to
vary the shooting trajectory and thus the direction and height of the jet of confetti
according to need. The tank can thus be combined with the containment body by means
of two or more brackets 11 each provided with at least one locking element 12.
[0038] Preferably, the at least two outlets are arranged aligned with each other so that
the respective shooting tubes are parallel to each other. In alternative, the outlets
can be staggered, so that to shoot the confetti with different trajectories.
[0039] In an alternative solution, the tank consists of a number of tank portions 3' equal
to the number of outlets. The portions are rotatably and sealingly constrained to
each other, so that to be able to vary the direction of each shooting tube independently
of the others.
[0040] The rotation of the tank, or of each of the tank portions, can be carried out manually
or in a motorized way.
[0041] In alternative or in addition, each tube can be combined with the respective outlet
by means of a foldable connection - not shown - that allows to direct it and to tilt
it at will, in order to achieve the desired effect.
[0042] The at least two shooting tubes are prearranged to be able to shoot the material
contained therein simultaneously, but preferably at different times.
[0043] To this end, each of the outlets of the tank are combined with connecting means 13
controlled to define a fluid connection between the tank and each of the at least
two shooting tubes so that to channel the compressed gas therein to cause the shot
of confetti. The connecting means 13 comprise at least two valves, each combined with
a respective shooting tube.
[0044] Preferably, each shooting tube is individually combined with a respective outlet
and the connecting means are arranged inside the tank.
[0045] The presence of at least two shooting tubes allows to make at least two shots with
a same device, without requiring any refilling, both to be able to shoot different
materials and to be able to shoot at different times during an event. In fact, thanks
to the connecting means as described above, the gas can be supplied to each shooting
tube independently of the others, thus also allowing to activate them at different
times according to need.
[0046] Preferably, the valves having control means 13' of the electropneumatic type are
used. Each valve can be provided with means for being controlled remotely so that
to cause the shots at the desired time. Advantageously, each valve is connected to
a control unit 14 to drive its opening.
[0047] In alternative or in addition, the control unit can be programmable for setting the
timing of the shots, or each valve can be provided with a respective timer to control
the opening at a preset instant.
[0048] The presence of at least two shooting tubes connected to the tank independently,
allows to improve the scenic effect obtainable with such device since more shots can
be made in close sequences, also of different materials, or at least two shots at
different times during the event. Moreover, such solution allows to decrease the number
of devices to be installed while obtaining the same effect.
[0049] In order to allow to make as many shots as the number of shooting tubes combined
with the device, if concomitant, the tank must be sized so as to contain a quantity
of compressed gas sufficient for each shot.
[0050] In alternative or in addition, the device can comprise more than one tank or a tank
internally subdivided into separate sections, so that the compressed gas present inside
each tank or in each section is sufficient to cause a respective shot from the shooting
tube combined therewith.
[0051] In alternative or in addition, the tank of the device can be combined with means
for connecting to a compressed gas source, in particular compressed air, or can be
initially filled with a quantity of compressed gas needed for a first shot and then
connected to one or more CO
2 cannisters provided with a pressure reducer and/or delivering means that can be activated
remotely in order to refill the tank once the gas therein has run out.
[0052] Wheels 14 for facilitating the movement can be combined with the main body 2. The
wheels are provided with locking means 14' to stabilize the device on the ground,
thus avoiding undesired displacements of the device due to the recoil of the shot.
[0053] In order to facilitate the movement of the device, movement handles 15, obtained
at the level of the body, can be provided to allow to firmly hold the main body.
[0054] Finally, the main body is sized and structured to be able to put away the shooting
tubes and other components therein, when the device is not in a using step, as shown
in figure 3. To this end, a lid 16 can be fastened to the main body for its closing
- as shown in figure 4 - when the device is unused and/or is in a transporting step.
