Description

Technical area

The present invention relates to an air supply for a compressed air gun with a projectile launch tube for firing shotguns, wherein the projectile launch tube is supplied via the air supply continuously air flowing through the projectile launch tube. As a shot body are primarily non-dangerous bullets such as air and soft balls or other game floors into consideration, which are suitable to be found on game or event modules and in the indoor and outdoor area in particular for the younger audience use.

State of the art

So-called. Fun shooters are known from the prior art, which consist of a compressed air gun with a projectile launch tube for firing shotguns, in which air is supplied to the projectile launch tube via a compressor and the air flows through the projectile launch tube.

These guns are equipped with a feeder that allows one or more projectiles to be manually and back-fed from above into the projectile launch tube so that it is catapulted forward out of the projectile launch tube by the air. In order to produce the necessary launch pressure, these compressed air cannons are usually equipped with air nozzles, a diaphragm valve and / or a spring.

From the US 2011/0094487 A1 an air supply for a compressed air gun is known, which comprises a projectile launching tube for firing of shotgun, the air supplied via the air supply continuously which flows through the projectile launch tube. In addition, the air supply for the compressed air gun comprises at least one continuous blower that continuously blows air from a base station, with the air blown out of the base station flowing to the projectile launch tube so that the shot body is catapulted forward out of the projectile launch tube by the air.

Presentation of the invention

The present invention is based on the object to provide a compressed air gun, which allows to a game or event module such as a bouncy castle, an air slide or other inflatable attractions (hereinafter referred to uniformly as event modules) to be connected.

According to the invention the above object is achieved according to the features of claim 1. Advantageous embodiments and further developments of the compressed air gun according to the invention are specified in the dependent subclaims.

The invention is based on the knowledge that inflatable event modules such as bouncy castles, air slides or other inflatable attractions always work with a permanent blower that constantly introduces air into the event module, since each of these event modules is basically made of sheets sewn together and this constantly air through the Sutures, lose; The permanent blower can not be switched off during use.

Embodiment of the invention

How out Fig.1 can be seen, the compressed air gun 1 is connected in this embodiment to the air supply of the event module 3 (here a bouncy castle), which includes a continuous blower 5, which continuously blows air 2 in the event module 3.

At least one carrier 4 for the air tube 8, through which air 2 flows to the projectile launch tube 8, is provided on the event module 3.

The provided on the event module 3 support 4 for the projectile launching tube 8 for unfolding his projectile launch tube 8 in the inflated state supporting shape is preferably filled with air 2 and is with the air 2 of the event module 3 by means of at least one air blower 5 and / or with the air 2 of the at least one additional air duration blower 6 filled.

The preferably hollow support 4 is therefore filled in this embodiment even with the air 2 of the air blower 5 and / or with the air 2 of the air blower 6.

The compressed air cannon 1 may be equipped with a feeder 10, which allows one or more projectiles manually inserted into the air tube 10, so that the projectile is catapulted forward by means of the air 2 from the air tube 10.

The compressed air cannon 1 can be made either of a hard material (metal, wood, plastic, etc.) or of soft materials, e.g. from together sewn PVC tarpaulins.

The compressed air cannon 1 should not necessarily be able to be fixed to the event modules, but also reversible (removable and replaceable). In the reversible arrangement of the compressed air gun 1, the air connection 4 should be completely or at least approximately air-tight lockable / closable be, for example by means of a Velcro cover or a zipper.

Also, the possibility is given to retrofit an existing event module 3 with a compressed air gun 1.

How out Fig.2 can be seen, the compressed air cannon 1 is connected in this embodiment to an additionally arranged on the event module 3 Luftdauergebläse 6, which permanently blows air 2 in at least one air line 7 within the event module 3 directly to the compressed air gun 1.

In this embodiment, the air supply for the projectile launching tube 8 thus takes place independently of the air supply of the event module 3 and in a further embodiment also independently of the air supply of the inflatable support 4, which is inflated via the air blown by the air duration blower 5 into the cavity 9 of the event module 2 ,

The air duct 7 can be a hose, a pipe or any other suitable flexible or rigid air duct, preferably made of a flexible material such as PVC, plastic, rubber or the like suitable materials, particularly preferably made of sewn PVC tarpaulin.

How out Fig. 4 As can be seen, the air duct 7 can also be configured as an outer duct outside the carrier 4. An exit end of the air duct 7 connects to the inner end 81 of the projectile launching tube 8 on the outside of the carrier 4. The inner end 81 of the projectile launching tube 8 is open, thus providing an air inlet to the projectile launching tube 8.
