Description

background

The invention relates to a device for the pneumatic or gaseous catapulting of loose objects, in particular articles fastened to a cable, in particular a linen bag, and a method for this and a production method of the aforementioned device.

State of the art

For example, there is a line throwing device for rope climbing equipment in tall trees. In this case, a projectile is thrown by a pressure of air through a throwing pipe in the air. Also for the tree care and the tree seed harvest as well as the cone picking such throwing devices are advantageous.

At the end of a throwing line a throwing body is attached and thrown over a selected branch fork in the height of the tree. Due to the weight of the throwing body, the throwing line is pulled over the branch.

To throw a throwing bag by hand requires a lot of experience and for many applications this is not possible at all.

It is a throwing device known with a throwing tube into which a throwing body is inserted. The projectile seals the pipe in the throwing pipe with a rubber plate and a seal, so that underneath a pressure chamber with compressed air can be achieved. To catapult the projectile, a mechanical lock is released. It is known a throwing machine, which includes a two-meter-long fiberglass poles and a rubber for catapulting.

Furthermore, when fishing a bait with a fishing rod is thrown very far by hand over your head. The presented throwing device could also be suitable for fishing on angling.

Problem to be solved

The object is to provide a device and a method of production and method for catapulting, which allow a simple and rapid production of the device and realize a precise method for catapulting loose objects.

Solution, benefits and design

The apparatus for pneumatically or gaseously catapulting loose objects is formed with an acceleration tube, a pressure chamber, a first actuatable expansion valve and a second loading valve, wherein the acceleration tube is formed at one end of a fluid line from the expansion valve as an extension and on the opposite end of the fluid line as Extension the pressure chamber is formed. The charging valve is formed in direct fluid communication with the pressure chamber and the catapultable object is loosely inserted into the acceleration tube in the run in front of the expansion valve and / or laid.

Such a construction of a device is very simple. The catapultable object can be designed as desired. A seal to the acceleration tube is not required. A seal to the accelerator tube would also be a hindrance, as this would cause a friction that counteracts the acceleration force. Such a device comprises few components and is very effective, whereby articles can easily be catapulted between 10 to 300 m at a corresponding pressure. Further advantages of this pneumatic projectile throwing device are that a minimal effort is achieved with a higher aiming accuracy, thus the implementation with the object of the throwing is considerably faster. Furthermore, the device is extremely robust and has a very low wear and an increased life. A thought The invention is manual pumping power, which is spent, for example, by manual muscle power to introduce pneumatic energy into a pressure chamber and controlled trigger this with a manual or electrically controllable lever.

According to a further embodiment, the pressure chamber is designed as a metal tube with a sealable with a sealing tape cover. A metal pipe has the advantage that extremely high pressures can be achieved.

Preferably, the actuatable expansion valve is a ball valve ball valve, in particular a ball valve ball valve with a manually operable lever. The advantage is that finished valves are known and available in standard sizes. The operation is easily varied with a hand lever. The hand lever has several advantages. One advantage is that the force for catapulting is controllable with the hand lever. If the ball valve ball valve opens quickly, the pneumatic pressure force expands very quickly and the loose object is accelerated very far with a high force. On the other hand, if the ball valve ball valve is opened slowly or only with a smaller gap, only a small acceleration force is generated. According to a further preferred embodiment, the ball valve ball valve is electrically controlled by means of an electric drive. Thus, the opening operation of the expansion valve is still precisely reproducible.

Preferably, the acceleration tube and the pressure chamber are substantially identical tubes. In particular, the device is essentially completely made of plastic materials, in particular of PVC. Thus, the device is very easy and inexpensive to produce. The seals on the ball valve ball valve are reinforced, for example reinforced with Teflon PTFE. Alternatively and more preferably, the device is in particular the tubes made entirely of metal from standard components with corresponding threads, for example in the format of one inch inside diameter or 0.5 inches inside diameter or any other standardized size.

Thus, the component cost is reduced because a high share of equal parts is achieved. The metal pipes are preferably standard components with corresponding threads, for example in the format of one inch inside diameter or 0.5 inch inside diameter or any other standardized size.

Preferably, the charging valve can be integrated in the adapter with the ball valve ball valve. For this purpose, it is preferred that the ball valve ball valve with a, preferably designed as a threaded opening, made for the charging valve. Thus, the charging valve can be screwed onto the one-piece adapter of the ball valve ball valve. Alternatively, the charging valve can be integrated, for example, in the sealable lid.

To make the throwing device as compact and inexpensive and reproducible, the charging valve is preferably a car valve. The car valve is preferably screwed to the fluid line adapter of the expansion valve. This results in a compact adapter with ball valve ball valve and car valve as a charging valve. Alternatively, as described above, the car valve may also be screwed to a lid for completing the pressure chamber.

In order to reduce the component cost, preferably the expansion valve is integrally formed as a fluid line adapter in T-shape with two openings for receiving once the pressure chamber and the other for the acceleration tube. The charging valve can be screwed into the fluid line adapter between the acceleration tube and the pressure chamber. Thus, the device can be produced efficiently by means of five solid components.

A method for producing a device, in particular an above-described, for the pneumatic or gaseous catapulting of loose objects provides the following method steps. On a tube, preferably made of plastic materials, in particular made of metal, in particular with threads standardized on both sides, a closure cover, in particular with a sealing band, is mounted in a fluid-tight manner as a pressure chamber, more preferably, screwed. On the opposite Side of the pressure chamber, an integrally formed ball valve ball valve is mounted, wherein the ball valve ball valve is mounted with a direct line to the pressure chamber and an acceleration tube is opposite extension of the ball valve ball valve and to the pressure chamber, a charging valve, in particular a car valve is mounted fluid-tight , preferably screwed. It is understood that as a ball valve ball valve any known from the prior art valve can be used, which produces the same technical effects as a ball valve ball valve.

Thus, with a few components a stable cost-effective, high quality launcher device created in the life.

A method for catapulting with a controllable force of a loose object, in particular with a rope attached thereto, more preferably, with a device described above comprises the following steps. In a pressure chamber, a fluid, in particular air manually or more preferably by means of a compressor filled by a charging valve and compressed. In an accelerating tube is loosely inserted or inserted an object for catapulting in front of an expansion valve. By opening the expansion valve manually or electrically, the article is accelerated and catapulted by expanding the fluid, particularly the air. The acceleration force is controlled by the opening angle and the opening speed of the expansion valve, in particular a ball valve ball valve. Thus, highly precise, for example, throw bags in tree care up to 100 m and significantly more in treetops or on industrial plants can be transported. Ropes can then be pulled up with a throwing line attached to the throwing bag. In the other field of use of fishing, for example, bait with a fishing line up to 250 m can be thrown far by the method described above.

Preferably, in order to achieve high ranges, the pressure chamber is at a pressure of at least 10 bar, more preferably 15 bar, even more preferably 20 bar applied. This pressure is preferably realized with a conventional bicycle pump or a conventional car valve compressor.
