Protective screen against aggressive animals

Abstract

A protective screen against aggressive animals, including a structure formed by frames provided with pointed elements which are installed for the purpose of creating secure zones that are protected against possible attacks from dangerous animals. A series of elemental modules having a square or rectangular tubular frame in polyethylene or hard plastic having four lances directed towards the centre but forming an angle with the plane defined by the frame. Each lance has a shaft of the same material as the frame and a steel metal lance point that is protected against corrosion.

Claims

1. A protection screen against aggressive animals for the purpose of creating secure zones that are protected against possible attack by dangerous animals, comprising a series of elemental modules; each module comprising a tubular frame of polyethylene or hard plastic, of square or rectangular shape, four lances directed toward a center point of the tubular frame; the four lances making an angle with a plane defined by the frame, wherein each lance has a shaft of the same material as the frame and a lance tip made of stainless steel.

2. The protection screen against aggressive animals as in claim 1, further comprising a plurality of appendages and orifices, wherein the appendages and the orifices have a circular cross section, and dimensions are such that any appendage is insertable with a slight play in any orifice of another adjacent frame, wherein the appendages and orifices are deposed on a plurality of corners of the frame and a plurality of contiguous sides of a perimeter of the frame.

3. The protection screen against aggressive animals as in claim 1, wherein once each elemental module is connected to another identical adjacent one, both in the vertical and in the horizontal direction, they are secured by means of flanges screwed together.

4. The protection screen against aggressive animals as in claim 1, further comprising a series of floats established in an upper part of the frame and a series of ballasts at a bottom part of the frame, both being tied to the elemental modules by means of belts.

5. The protection screen against aggressive animals as in claim 1, wherein the screen is seated directly on foundations of concrete, or air bricks.

6. The protection screen against aggressive animals as in claim 1, wherein the modules are painted with black, red and yellow stripes.

DETAILED DESCRIPTION OF THE DRAWINGS

(10) Protection screen against aggressive animals (7) (FIGS. 1 to 6) consisting of a structure formed by a plurality of frames provided with pointed elements which is installed for the purpose of creating secure zones that are protected against the danger of aggressive animals of any species, which in a preferred embodiment of the inventors consists of a series of elemental modules (1) composed of a tubular frame (2), of square or rectangular shape, from whose corners emerge four lances directed toward the geometrical center but making an angle with the plane defined by the frame (2). Each lance is composed of a shaft (5) of the same material as the frame and a lance tip (6) made of marine stainless steel.

(11) Each frame (2) has four appendages (3) and four orifices (4) situated at the positions indicated in FIGS. 1, 2 and 3. Both the appendages (3) and the orifices (4) have a circular cross section and their dimensions are such that each appendage (3) can be inserted with slight play in any given orifice (4) of another adjacent frame (2).

(12) Under these conditions, it is possible to fit together one elemental module (1) on top of another identical adjacent one, whether in the vertical or the horizontal direction, making it possible to form a protection screen (7) of any given dimension.

(13) The elemental modules of the invention make it possible to form protection screens either on terra firma or in the aquatic environment.

(14) As an example, FIGS. 4 and 5 are included, representing a practical application in the aquatic submarine environment to form a screen (7) intended to protect zones of beaches, industrial exploitation, research activities, or any other similar ones in which it is desirable that the swimmers or persons working in the given zones may do so in total peace and safety as regards aggressive or dangerous animals.

(15) The screen (7) has been formed by the juxtapositioning of a series of elemental modules (1) with their appendages (3) inserted into the corresponding orifices (4), ensuring that they are immovable with respect to each other by means of flanges (8). FIG. 4 details an enlargement of a flange (8) with its fastening screw.

(16) The line of elemental modules (1) which should be situated near sea level (9) is joined to a series of floats (10) and the line of elemental modules (1) which should be situated at the sea bottom is joined to a series of ballasts (11) which ensure that the whole is immovable. The floats (10) and ballasts (11) are joined to the frames (2) by means of belts (12) or similar fasteners.

(17) In FIG. 5, corresponding to the profile view of the screen (7), it is seen that the lances with their respective shafts (5) and lance tips (6) point to the right, which is where the open sea and consequently the dangerous animals are assumed to be. The left zone would then be the protected zone.

(18) FIG. 6 includes a practical application corresponding to an enclosure on terra firma, where it is seen that the elemental modules (1) are seated directly on a linear foundation of concrete, air bricks, or any similar material.

(19) The modular structure is extended lengthwise by adding two, three or more elemental modules (1) which are secured by posts (14). The number of modules in the vertical direction will depend on the type of animals representing the danger in the given instance.

(20) As an interesting supplement, for purposes of deterrence, the inventors imagine the use of painted stripes in the colors which are the most significant in regard to animals, such as black, red, and yellow.

(21) It is not considered necessary to expand the content of this description for a person skilled in the art to be able to understand the scope and the advantages deriving from the invention, as well as to develop and carry out its subject matter. Even so, it should be understood that the invention has been described in a preferred embodiment, so that it may be susceptible of modifications without this affecting or assuming any change in the foundation of this invention. That is, the terms in which this preferred description of the invention has been expressed should always be taken in the broad and not limited sense.
