Description

Device for the expulsion of confetti.

Object of the invention

The present invention relates to a device for the expulsion of confetti of the type of which they include confetti throwing tubes attachable to mouths outlet of pressurized fluid, regulated by solenoid valves shot, from a refillable tank, fluid container to Pressure.

Background of the invention

In certain shows, the launch of various elements, such as confetti or streamers, which help create a playful and cheerful atmosphere.

The confetti launch can be made from various ways, such as manual launch by people from places at a certain height or by small devices, such as bags filled with pressurized air and presenting on one side a compartment full of confetti, with a weakened wall, shaped that when you press the bag and increase its internal pressure it opens said compartment the confetti being projected at a distance higher. However, these devices are still within a very wide range. limited, and therefore unsuitable for large events, such such as outdoor concerts, sports stadiums or similar.

In the Spanish utility models ES1055511U and ES1058758U, of the same applicant, describes confetti ejection devices comprising mainly a carrying case with a grip handle, in whose interior is housed a tank with valve safety and gauge gauge, intended to contain a gas to pressure and that has a filling mouth and at least one mouth of outlet connected to the aforementioned tank by means of solenoid valves Shooting.

These solenoid valves are operable joint or independent by means of an electrical circuit of control. The outlet includes means for retention of the throwing tube that contains the confetti to be ejected.

The suitcases can have rubber feet or elastic material that make it more stable during the discharge of pressure ejected from the confetti. The briefcase can also present vents to allow gas evacuation of the tank in case the safety valve acted. The tube or launch tubes can be connected by means of cables steel with the mouth to avoid being fired at the moment of the drive.

However, these devices have some handling and stability problems, mainly due to its considerable weight and conception. The briefcase is heavy and should be driven by a forklift or similar, serving the only handle it has on its top, only to remove the cover that allows access to its interior. Further, the deposit is fixed mainly by means of strapping surround and anchor at the bottom of the case, which facilitates its extraction, but produces excessive oscillation during transport, so that the deposit is released. The tubes of launch are large and difficult to handle mounted, so however, the successive operations of Coupling and decoupling should be easy to perform.

Description of the invention

The device for the expulsion of confetti, object of this invention, presents some technical peculiarities intended to facilitate its manageability and safety of preparation for use

In effect, the gas cargo tank is is attached to a support plate in a solidary manner by welding, presenting this support plate holes of fixing to the bottom of the case by means of through screws, with what is achieved that the deposit is linked to the briefcase more firm and durable, gaining in the strength of its anchor, especially during transport and handling.

In addition, the briefcase presents on two sides opposite, respective transport handles approximately centered and that enable the possibility of manual transport by two operators grabbing a handle respectively. This reduces the need to use a truck or other transport device, complying with the ergonomics regulations for handling the device.

These handles are preferably constituted by a recessed recessed in the wall of the briefcase, and in which it is articulated handle, "U" shaped, pivoting at two points of articulation, thus facilitating its folding when not They are operational.

The means of retention of the pitcher tube to the outlet are made up of a flange of cams and a mouth with a surrounding coupling groove. This configuration, also called "camlock" type is of fast and safe positioning.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a perspective view Of the device.

- Figure 2 shows a longitudinal section Of the device.

- Figure 3 shows an elevation detail of a grip handle

- Figure 4 shows a detail of the fixation of the pitcher tube over the outlet.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the device comprises a carrying case (1) with an upper access cover (11) and grip handles (2) opposite sides arranged for gripping by two Operators during transport and positioning. Each of these handles / 2) is constituted by a recess (21) embedded in a opposite side wall of the case, and which has the handle articulated (2), U-shaped configuration, pivoting at two points of articulation (22) spaced. The briefcase (1) presents bottom rubber feet (12) elastic.

Inside the briefcase (1) is a gas tank (3) under pressure, such as compressed air or anhydride carbonic in this case, this tank (3) being joined by welding to a lower support plate (31) for anchoring to the bottom of the case, using screws (32) arranged by holes (33) of said support plate (31).

This tank (3) has an associated valve safety (30), a pressure gauge (34), a filling port (35) and an outlet (36) connected by an electrovalve (4) shot and an elbow (38) protruding from one side of the case (1) for the coupling of a confetti throwing tube (5), by means of retention. This tube coupling pitcher (5) is performed using a cam flange (39) and a mouth (51) with surrounding fixing groove. In an alternative of embodiment between the launch tube (5) and the outer elbow (38) is You can find a sturdy steel cable (52) that prevents your projection.

The solenoid valve (4) is connected to a electric control circuit (6), which is operated by a remote control (61) plugged into external connections.

In an alternative embodiment, the briefcase It has vents (13) for the evacuation of the gas evacuated from the tank by the safety valve (30) in the same.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
