Description

The present invention relates to a quick-opening system of connections between nets, tarpaulins, support structure and the like according to the preamble of claim 1 and a connection device for carrying out the quick-opening system.

Hail nets, protective nets, protective tarpaulins and the like are often used, for example, in agriculture or in parking lots to protect plants or machines from the effects of the weather, such as hail or even sunbeams. The quick-opening system according to the invention can also be used, for example, for fish nets, ship sails, tarpaulins for animal feed, curtains for stage curtains, truck tarpaulins and the like.

Generic systems are for example from the EP 2 875 721 known. In this publication, an opening / closing system for hail nets, protective tarpaulins or the like for agricultural equipment is described, which is provided with a support structure by vertical posts, by wires parallel to the rows of trees, by to the rows of trees transversely tensioned wires through to Ground inclined and anchored to the same wires or by spreadable above the plants, each collectible by rolling tarpaulins, each of the individual nets is mounted between a pair of parallel rods, at the two ends on the rows of trees and the arrangement of the wires transverse profiles are rotatable and each network is fixedly attached to one of the longitudinal edges of one of the rods, while the opposite edge is provided with strands or tarpaulins spaced from said edge with one of the edges, while the opposite ends of the entrained rotatable St are attached.

This is an example of an automatic system, but often these systems still have a manual opening.

DE 10 2000 10 049959 describes an arrangement for the detachable connection of components using a tubular fillable filling body, which connects the components along the entire contact surface. The system described does not teach the release of multiple connections, but only a single connection. The described system further teaches that the connection maintains a high pressure connection within the tubular connector. This has considerable disadvantages, especially in the open, since under the influence of weather conditions, the volume changes, in particular the reduction in volume can bring about the solution of the compound.
The system described in the German publication is intended primarily for a rapid and preliminary construction and not to solve several interconnected connections of one or more parts.

Also the GB 22 71 366 describes a connection made by spreading a single component. Also in this case, the connection is established by the spreading. The publication reveals the same problems described in the German publication.

The entire publications described disclose a compound which is made by spreading an inflatable part and not the solution of the compound by spreading.

The solution of the compound is carried out by the volume reduction. All publications teach the single connection, not the solution of multiple point connections. The systems described are not suitable to intervene in emergencies.

To improve protection, the individual nets are connected by a series of connectors to form a single unit. These fasteners must be solved individually.

If special weather conditions prevail, rapid opening of nets, tarpaulins or the like may be required to avoid tearing them and destroying the items they should protect, such as orchards and the support structure, which are high Costs caused. Under opening means that the nets, tarpaulins or similar are withdrawn into a rest position.

For example, a sudden snowfall in April 2016 caused millions of damage in Austria due to the snow weight on the nets and the consequent yielding of construction with the nets and damage to trees in orchards and grapevines.

There are a variety of weather conditions that require rapid opening, such as hail or strong wind and all those conditions that overburden the nets, tarpaulins and the like.

The object of the present invention is to provide a system that provides the fast Opening of protective nets, hail nets and protective tarpaulins in particular allows the solution of the connecting parts.

This object is achieved by a quick-opening system of connections between nets, tarpaulins, support structure and the like according to the characterizing part of claim 1 and an apparatus for carrying out said system.

The quick-opening system of connections between nets, tarpaulin, support structure and the like comprises at least two spaced-apart devices, each connected by a first to a net, a tarpaulin, support structure or the like connected support member and a second with a second network, tarpaulin, support structure or the like Support member are formed, wherein at least one of the two support members is connected to a second network, tarpaulins, or the like, wherein the first and the second support member are connectable to each other via a preferably snap-releasable connection according to the invention, wherein between the first support member and the second support member, a spreading element is preferably interposed with volume change by means of a fluid which unlocks the connection preferably snap-like, and wherein the two spreading elements preferably under volume change of at least two devices are connected together.

Under spreading is understood in this description and in the appended claims, a change in the shape of the spreader in one direction, which is expressly including the change in shape with constant volume or substantially constant volume of the spreader, in which only spread the width of the spreader becomes.

Advantageously, the two networks are aligned with each other and are connected to each other via a connecting device. This connection device is formed by a first, attached to the first network support member and a second, attached to the second network support member. The attachment can be done by screws or by a clamp connection or by gluing and / or welding. If you want to connect the two networks, the two support members are advantageously engaged with each other by snap or snap.

In the connection between the first support part and the second support part, a spreader element is preferably interposed with volume change. In this expansion element, the volume change can be caused by a fluid. For example, an expansion element made of elastic plastic is spread by means of a fluid, for example, air, and with the spreading, a projection or a nose, which formed the connection of the first support member disengaged and unlocks the connection. This expansion element is connected via a hose with at least one second expansion element, which is arranged in a second connection device. In this way, under pressure increase within the hose / line, the shape of the expansion elements can be spread under volume change, which are arranged in the connecting devices, so the compounds can be separated.

Advantageously, the pressure change can be effected by a compressor or even only by a gas cylinder which is connected to the hose / line.

The connection device can be connected by hand and also unlocked by hand when there is no emergency or when the system for generating the pressure should be faulty.

In 1 is with the reference number 1 a connecting device for opening of protective nets / hail nets, protective tarpaulins or the like.

The connection device 1 for the opening comprises a first support member 2 , This first support part 2 is attached to an edge of a not shown first protective net / hail net, protective tarpaulin, support structure or the like separable or fixed firmly, for example by a snap connection. The mounting part 2 has a receptacle for a spreader, in this embodiment, under volume spreading 11 , on. This receptacle also forms the connection for a second holding part 3 connectable to a second protective net / hail net, protective tarpaulin support structure or the like (not shown), at least one of the two support members 2 . 3 is separable or permanently connected to a protective net / hail net, tarpaulins, or the like. The connection between the first 2 and the second support part 3 is advantageously by snapping, for example by means of a nose 3a of the support part 3 formed in the mounting part 2 is locked.

The spreading element 11 For example, with volume spread exerts no pressure on the connection between the first 2 and the second support member in the rest position 3 out. If a rapid opening of the connection between the two networks is required, then in a preferred embodiment, fluid is transferred via the hose / line 10 within the central expansion element 11 , for example, with volume spread, flowed. By the fluid, for example, air, the pressure is increased and the expansion element 11 changes its size by spreading and displaces the nose, for example 3a so to the connection between the first 2 and the second support part 3 to unlock or adjust a part of the support part 2 to solve the lock.

The hose / pipe 10 at the exit from the central expansion element 11 for example, with volume change is associated with a second expansion element, for example with volume change, which is arranged in a second connecting device of the same kind, which connects the first protective net / hail net, the protective tarpaulins or the like with the second protective net / hail net, protective tarpaulins or the like. In this way, the first and the second protective net / hail net, protective tarpaulins or the like are connected to each other by at least two devices according to the invention 1 connected and by introducing / increasing the pressure inside the pipe, which is a hose 10 can succeed, at least two connected in series connecting devices 1 simultaneously open quickly and quickly. In this way, a system according to the invention is formed. The activation can be done for example by means of a compressor, not shown, or a gas cylinder, in particular air, which the hose 10 the system is supplied.

Several connecting devices 1 arranged in series and / or also in parallel, for example, for several rows of apple orchards can be driven by a single pressure generator or compressor.

The spreading element 11 for example with volume spreading is by means of a hose 10 connectable both at the entrance and at the exit with at least a second expansion element, for example, with change in volume by spreading.

Advantageously, it is formed by a tubular element made of metal, plastic or similar features, the side openings 11c having. This metal tube element is surrounded by stretchable plastic, which is a chamber 11b forms. This chamber 11b Under spread, the size changes depending on the pressure. Advantageously, the chamber 11b with a network 11a overdrawn. This network 11a may for example consist of a plastic net, a textile cover and / or fiber sheath and / or textile braid and serves to avoid the breakage of the chamber due to excessive pressure. To escape fluid from the chamber 11b To avoid, can shutter elements 13 be provided, which is the chamber 11b keep sealed.

In a preferred embodiment, the system according to the invention comprises means for the remote execution, remote release. The inventive system is remotely activated in, for example, a gas / air cylinder and / or a compressor connected to receiver devices. These receiver devices may be well-known devices, for example, means capable of receiving, for example, WIFI signals from the fixed or mobile telephone network or via radio waves or, for example, over a data network. Upon receipt of a particular signal, the compressor and / or gas / air cylinder is activated and directs the fluid into the line 10 and unlocks the first mounting parts 2 from the second support parts 3 ,

The remote release could also be done by means of sensors which detect the amount and type of precipitation, for example distinctively between snow, rain, sleet and / or hail and depending on the nature of the precipitation and the amounts, the system can activate the automatic opening.

Also, the detection of the wind by sensors with the wind speed and its duration of action can be used in one embodiment of the system to have the system activate automatic opening. For example, the sensors may be mounted directly in the orchard, ie, by monitoring them Sensors and ultimately under the recorded meteorological conditions, alerts can be sent to the end user.
In a system according to the invention, these warning messages can be sent via various notification channels, such as via app; Mail; SMS; Web portal etc. are transmitted. This allows the end user to trigger the system remotely. For the triggering are also means of communication via App; Mail; SMS; Web portal etc. possible. Behind this are usually server structures, which collect the data centrally, process and output via the corresponding channels or transmit.
In a preferred embodiment, the system can be triggered independently by predefined threshold values of the sensor data. In addition, it is possible that meteorological data from surrounding areas near stations / sensors as decision makers are included. By adjusting the data, an error ie, for example, a faulty sensor and / or measurement can be detected and a non-necessary triggering can be prevented by an error correction or by this plausibility check.

In a further embodiment, the spreading takes place with a constant or substantially constant volume of the expansion element. In this embodiment, the volume of the expansion element remains constant or substantially constant and takes place, for example, via the extension of the width of the expansion element in the center. This expansion is controlled via the material and / or additional elements with consequent reduction in the lengths and / or width of the expansion element.

The material used for the embodiment of the expansion element can be a composite material, for example made of plastic with incorporated fibers, or a resin, polymer material or the like.

The tarpaulins or nets described in this specification and in the appended claims may also be tarpaulins or nets formed of several individual tarpaulins or nets. The support structure may be a wall or a stake or the like to which the tarpaulins, nets and the like are releasably connected.

It is finally clear that additions, modifications or variants which are obvious to the person skilled in the art without departing from the scope of protection defined by the appended claims can be made to the system described hitherto and to the apparatus described so far.
