DESCRIPTION

Tensioning and immobilization device for anti-hail, anti-insect or weather networks.

Object of the invention.

The object of the invention is a device for tensioning and immobilizing anti-hail, anti-insect or climate networks, which are installed by means of rows of support posts containing longitudinal cables fixed superiorly to the respective rows of posts.

These networks are fixed on one side or on their central part to these longitudinal cables and are joined together discontinuously by their other side end; said networks forming a gable roof, with the ridge in the longitudinal cables and the lower part just in the center between these rows. The network can be entire from center to center of contiguous streets or they can be two half networks joined at the ridge.

The structures, in order to avoid lateral movement, usually have a transverse wiring that joins the posts perpendicular to the longitudinal cables.

This tensioning device has constructive particularities oriented to make a stable fixing of the networks by the area corresponding to its lower end, that is, by the intermediate zone of two rows of posts, longitudinally along the entire network and supporting from the upper transverse wiring of this structure.

In this central area, the networks are currently not fixed effectively and their movement by wind and excessive hail loads can cause breakage.

premature networks.

Field of application of the invention.

This network tensioning and immobilization device is applicable in the agriculture sector; although the protection of public or private outdoor areas for parking of vehicles or installation of various equipment is not ruled out.

State of the art.

Currently there are different network protection devices on the market, the ones that have a greater relationship being those that include: rows of support posts on which first longitudinal cables are mounted, to which they are fixed by means of staples or elements similar the upper end of a protection net, said networks fixing each other, discontinuously, by their lower end; so that the pairs of networks arranged between two rows of consecutive desserts form a kind of gable roof, descending towards the longitudinal middle area of the space delimited by the mentioned rows of consecutive posts.

Since these protection devices are installed outdoors, it is necessary that the fixation between the second ends of the nets, which converge towards the lower zone, be fixed between them discontinuously, so that brown hail on the nets can descend by gravity towards the central zone and fall by own weight through the open spaces defined between the successive fixations of the lower end of the networks.

Another requirement of these anti-hail protection devices is that the networks form the aforementioned downward cover to two waters and that they remain in said position with a certain tension, in order to avoid that the wind can raise and cause an uncontrolled movement of the networks subjecting them to accelerated deterioration, and getting the hail that falls on the nets to go down

towards the central evacuation zone and do not form bags in intermediate areas, loading the nets with a weight that can cause them to break through the areas of engagement with the first cables or through the lower areas of fixing the networks with each other.

The means currently used to achieve this tension and fastening of the nets by the lower zone thereof consists in the use of elastic braces located below or above the nets and which are hooked by one of their ends to the areas of union of the lower ends of the networks, and at the opposite end to the posts, to wires of the respective row rows or there are also systems with elastics that join intermediate reinforcements of the network to each other forcing the flat network and a small net funnel to the center between rows.

A disadvantage of these elastic braces is that when exposed to the weather and continuous traction they deteriorate with a certain speed, being necessary to replace them with a high frequency, which entails an important economic and ecological cost.

These elastic braces pose other drawbacks, among which it is worth mentioning that they are directly hooked to the net and work in a timely manner and can cause their breakage, in addition to the hindrance to the passage of work machines for pruning or collection that are those that are arranged under the net, and inclined downwards towards the fixing point with the corresponding post.

The applicant of the present invention is unaware of the existence of other background of protection devices with networks, similar to those of the type described and that allow to satisfactorily solve the exposed problem.

Description of the invention.

The device for tension and immobilization of anti-hail, anti-insect or

Climate conditions, object of the present invention, presents constructive particularities oriented to satisfactorily solve the problem set forth above, having fastening means for the lower end of the networks, from its upper part, without using elastic means and so that said fastening means do not constitute a hindrance to the working machines (pruning, collection, etc.).

This tensioning and immobilization device is applicable in networks fixed by an upper end to longitudinal cables mounted on rows of posts related superiorly to each other by transverse cables; said networks being connected to each other discontinuously by their lower end to form a gable roof, with the ridge in the longitudinal cables and the lower end centered longitudinally between two rows of posts.

According to the invention, said immobilization device comprises positioners, by way of "V", which have a core from which two wings are oriented towards the upper area and which are fixed to the transverse cables of the structure, with the possibility of lateral and height adjustment, by means of fastening clips; It also includes a synthetic or metallic longitudinal wire or cable that is fixed to the soul of all the “V” positioners in its lower part and that is placed just in contact and above the unions of the protective nets in the center of the streets, that is, at the bottom of the chapel, where the hail will be unloaded. This device is in contact with the network connections but allows the network to descend freely in case of an unusual hailstorm.

In an embodiment of the invention, this device includes, optionally, threads, cables or elastics placed below the net for support of this when it is opening or closing and thus preventing it from descending until it touches the crop or elements that are below and avoid breakage in case of wind.

These wires, cables or elastics range from one ridge to another descending

parallel to the net to its bottom and continuing to the next ridge of the consecutive row. They rest on the lower part of the soul of the “V” positioner, without ever joining it.

It is interesting that these cables, wires or elastics are flexible and allow to increase their length so that the network can descend in case of a great hailstorm.

With the aforementioned characteristics, the metallic or synthetic longitudinal cable or wire located on the network joints in the central part of the protected streets, prevents the junction zone of the lower ends of the protection networks from being able to move laterally uncontrollably and vertically by wind effect, for example. In addition, the mounting of the positioners on the transverse cables by means of fastening clips allows the position of the souls of said positioners to vary both laterally and in height and to adjust the inclination of the two waters formed by the networks.

On the other hand, the option of the elastic lower cables or wires supporting the networks together with the second longitudinal cable makes a greater stable fastening of the networks in a position of use in addition to preventing their coffee on the lower crops during folding and annual deployment of the networks in the ridge.

This second cable or longitudinal wire (6) prevents the lower ends of the networks (2a, 2b), fixed between the platelets (8) can be raised by the action of the wind or the hail can accumulate in the form of bags, minimizing deterioration of the networks; in addition, the height of this second longitudinal cable (6) can be adjusted by adjusting the height of the positioners (4) with respect to the transverse cables (3), guaranteeing a correct tensioning of the networks (2a, 2b) inclined in the transverse direction .

In an example shown in Figures 1 to 4, this device comprises elastic lower cables (7) supporting the networks, provided with two ascending branches from the core (41) of the positioners (4) to the upper end of the posts ( 1a, 1b) of the consecutive rows.

As shown in Figure 3, the mentioned elastic lower cables (7) also allow the support of the networks (2a, 2b) in an open position, that is, folded towards the respective rows of posts (1a, 1b) when the ends
