Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Possible designs are now illustrated in more detail using the appended schematic representations, of which:

[0023] FIG. 1 presents a schematic view of the preferred device.

DETAILED DESCRIPTION OF THE DRAWINGS

[0024] FIG. 1 shows a device 1 for the pneumatic or gas-operated catapulting of a loose object 2. In this particular case, the loose object 2 is a cloth sack which has a ring onto which a rope 3 is attached. The cloth sack is filled with sand or another heavy object, such a lead, to enhance the gravitational force. The device 1 comprises an accelerating tube 4, a pressure chamber 5 as well as an expansion valve 6 and a load valve 7. The load valve 7 is designed with a direct fluid connection to the pressure chamber 5. The catapultable object 2 is inserted loosely into the barrel 8 of the accelerating tube 4 in front of the expansion valve 6. The expansion valve 6 is preferably a ball tap-ball valve with either an electrical control with an actuator or with a manual hand lever 9, as shown in FIG. 1.

[0025] The pressure chamber 5 is also designed as a pipe, in particular of the same size as the acceleration pipe 4 equipped with a thread on both sides.

[0026] A lid 10, impermeable to fluids and sealed tight with a sealing tape 11, for example a Teflon tape 11, is screwed onto the end of the pressure chamber 5. A fluid line adapter 16 is designed as a T-shaped component with the expansion valve 6. The load valve 7 can be attached by screwing at the junction of the T-piece. The load valve 7 is preferably an auto valve. The auto valve can be coupled using known autovalve connections with manual pumps, such as, e.g. a bicycle pump or compressor pumps. The load valve 7 is arranged below the expansion valve 6 such that the direct fluid connection to the pressure chamber 5 is established, and locking is possible by means of the expansion valve 6 to the accelerating tube 4. In order to provide a light device 1, the total design of the device 1 is manufactured from plastic materials, in particular PVC. Alternatively, the device 1 is mainly manufactured of metal. Under certain circumstances, this therefore ensures a significantly higher pressure build-up in the pressure chamber 5. The pressure chamber 5 can store different pressures of at least 10 bar, more preferably 15 bar, and still more preferably 20 bar. By means of the expansion valve 6, which, as shown in FIG. 1, is preferably attached to a T-shaped fluid line adapter 16, the force for catapulting the object 2 can be individually adjusted and controlled. For this purpose, as shown in FIG. 1, the pressure chamber (5) is screwed onto the fluid line adaptor 16 or is screwed into the accelerating tube as an extension. As the load valve 7, the auto valve is screwed into the fluid line adapter between the accelerating tube 4 and the pressure chamber 5.

[0027] The device of this type 1 is suitable for throwing bags upwards over a branch in an accordingly controlled manner during tree maintenance. The device is also suitable for use in fishing to catapult fishing line hooks with bait over a great distance, for example, up to 300 m. It can also be used to catapult replacement projectiles used with bows and crossbows, for example, safety arrows.

[0028] The manufacturing method of the device 1 is characterised by a few steps, regardless of whether the entire device 1 is manufactured mainly of plastic materials or of metal, a tube, in particular with standardized threads on both sides, a sealing lid, impermeable to fluids, is mounted, in particular screwed, onto the pressure chamber 5 with a sealing tape 11. A fluid line adapter 16 with a ball tap-ball valve 6 is mounted on the opposite side of the tube and on this, an accelerating tube 5 is mounted opposite in the extension of the ball tap-ball valve 6. A load valve 7 being an auto valve, impermeable to fluids, is mounted on the pressure chamber 5, preferably on the fluid line adapter 16, below the ball tap-ball valve 6.

[0029] The preferred method includes the following steps. In a pressure chamber 5 of the device 1, a fluid is filled and compressed through air, manually or by means of a compressor, by the auto valve being the load valve 7. For example, a pressure gauge can be provided on the manual air pump or compressor to verify the pressure chamber pressure. The ball tap-ball valve 6 is thereby closed. The catapulting object 2 is inserted loosely in front of the expansion valve in the barrel 8 of the accelerating tube 4. Manual opening using the hand lever 9 of the expansion valve 6 or an electrically controlled opening of the ball tap-ball valve expands the air, i.e., the fluid from the pressure chamber 5 catapults the object 2 upwards. The acceleration force of the device 1 is controlled on the one hand by the opening angle and by the opening speed of the expansion valve 6.
