D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of the present report, refers to a COSI] set of mechanical means configured to prevent cable theft in tarol and other similar urban furniture elements by blocking the cables inside same of the element where they are, so that it is not possible to remove them. Likewise, the necessary steps for its assembly are described.

More specifically, the system consists of a crosshead and a disk that are arranged inside the lamppost, where its special configuration causes the cable to be protected to adopt an inclination with respect to the registration cover so that when trying to remove the cable without first disassembling the system, said cable is braked against the disk, being unable to move.

FIELD OF APPLICATION OF THE INVENTION

ES present system provides a protection system for streetlight cables and similar elements of street furniture, so it will have application within the urban furniture manufacturing industry.

Since the main application is to avoid cable theft carried out by opening the registration cover, it will bring significant savings in the conservation and maintenance of this type of elements. BACKGROUND OF THE INVENTION

The electricity supply lines for street lamps are currently subject to theft with a frequency that sometimes causes the maintenance of the installation to be economically unfeasible. The copper of these lines is an expensive material and currently easy to subtract. what causes the fact c. One of the options to be taken to hinder this type of robbery is to make it difficult to access the registration box next to each lamppost. It should be mentioned that the holder of the present invention is also a device for this purpose. However, there is the circumstance that once the access to the wiring from the casing has been canceled, it is also possible to reach said cables from the lamp post itself, so it is necessary to arrange an anti-theft device or system that also prevent the manipulation of the cables from that point.

Different documents are known where different systems are described to achieve the aforementioned objective of wiring protection within the lamppost itself. However, all the aforementioned devices or systems present the problem of their difficulty of assembly, causing either that they cannot be disposed on lampposts already installed or that the maintenance operation of a lamppost is complicated, increasing the cost of said operations in big measure.

It is therefore desirable that the appearance of a cable anti-theft system such as the one described herein, where such a system is quick and easy to install, while for maintenance operations it is not It is necessary to disassemble it completely, simply removing only a part since the rest of the system does not make maintenance work difficult.

It is known the existence of a system to prevent cable theft in street lamps, described in the utility model ES 1077130U consisting of a cover and a base, both circular in shape, which are introduced inside the 3rd lamppost, disposing between both Elements are staples that are attached to the cable thus preventing its passage through the cover. This system presents the problem of the difficulty of assembly and disassembly both for its installation, since it consists of multiple elements, as for maintenance work, where an important disassembly work will be necessary to be able to access up to the wiring.

The patent ES 2375029 describes a protection system where a piston disposed inside the lamp body is disposed on the elements to be protected, where it can only be removed by using a specific tool, without which it will not be possible to access Inside the lamppost. However, this system cannot be used in installed lamps, besides supposing a significant increase in the final cost of manufacturing the lamppost. Utility model 1 077563 U proposes the connection to the power lines of the lampposts of a sohdifiable element, which when adhered to these prevents the removal of the cable.

The utility model ES ii 34264 O presents an anti-theft cable system by means of a disk that is pierced by electric cables and that has elements that prevent the cable from being removed through the holes in the disk, while the disk itself is fixed by pieces added to the lamppost body.

It is not known by the owner of this report, therefore, the existence of any closing device or system that has the aforementioned advantages and that does not have an operating mode. similar, so it is considered that the invention is configured as an obvious novelty. Based on this, the corresponding protection offered to this type of invention is requested. DESCRIPTION OF THE INVENTION

The anti-theft system of cables object of the present memory is formed by a crosshead and a toothed disk which are arranged inside the lamppost whose cables are to be protected and joined by a safety thyme that prevents their removal.

Both elements are arranged through the lamp post, where the crosshead is located at the bottom of the set that makes up the system. This crosshead is formed by two crossbars that cross and whose length is slightly less than the internal diameter of the lamppost. At the ends of the crossings, fixings are used to hold the crosshead inside the lamppost by simple friction with the walls in the assembly operation.

These fixings will consist of screws that are advanced with the help of a wrench until they press on the inner walls of the lamppost. It is possible to have only two mobile fixings, such as those mentioned, leaving the other two fixed, thus being enough to fix the crosshead inside the lamppost. At the crossing point of the crossbars, there is a threaded hole for the insertion of the safety thyme that will connect this element to the toothed disc.

The toothed disc that is placed next to the crosshead, resting on it, consists of a disk of approximate diameter to that inside the lamppost. Its perimeter is provided with teeth, differentiating two zones, a larger area (approximately 270 ° of the circumference) with a finer teeth, and another one of smaller extension (approximately 9 (f) with a greater toothing that allows the wiring to pass in the space between the tooth and the inner wall of the lamppost. In its center the disc has a through hole for the security screw , where said hole is continued by a bowl (which is oriented towards the crosshead) Ja which has at its final end a narrowing for the settlement of the head of the safety screw that joins crosshead and toothed disc.

Once the toothed disc has been arranged on the crosshead, correctly oriented, it will be enough to screw both elements by means of a safety thyme or similar element, they are firmly attached.

The proper position for placement is determined by the cables inside the lamppost. Since these ascend towards the register by the part furthest from the door of the registry, the position of the teeth of greater dimensions of the disk will be this same, being placed as far from the door of the registry possible. Each of the cables of the lamppost will pass through one of the gaps between the teeth of the disk itself and the inner wall of the lamppost.

In addition, the cables must pass through the crosshead just through the opposite part, that is, the one closest to the registration door, during placement so that these cables are with a curvature determined by the crosshead and the disk, which make that the cable passes from one part to another inside the lamppost. In this way, an attempt to remove the cables by pulling them from the register causes the cables to press on the valley that forms a pair of teeth of the toothed disc, thus being fitted and prevented from movement. Excessive tension would eventually cause the cables to be cut, making it impossible to steal the line. The maintenance operations are simple to carry out by means of the present system, since it only has to disassemble the toothed disc by removing the safety screw, once again arranging the disc once the task is completed. The stability of the crosshead and disc assembly is important to avoid that pressing it could be rotated in a plane transverse to the axis of the lamppost, so that it would be useless. For this, the crosshead has in its lower part some supports that start from the crossing and reach the inner walls of the lamppost.

Another important safety element of the disc consists of a pair of stops, greater than or equal to the length of the bowl, which will prevent the possibility of rotating the disc around the axis of the lamppost. These stops would impact the crossbars when trying to rotate the disk, which makes it impossible to turn the disk to eliminate the curvature of the cable that causes pressure on the disk when the cable is pulled from the registration door.

Optionally, the crosshead may have a hole in one of its crossings for the passage and buckling of the ground conductor.

DESCRIPTION OF THE PREFERI DA FORM

In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below, not intended to be Absolutely the present example limit the scope of this.

The present system, designed to prevent cable theft in street lamps (1) and other similar street furniture elements, is composed of: a crosshead (6) formed by two crossbars of equal length less than! internal diameter of the lamppost (1), where at the ends of the crossbars there are some fixings (II) and at the crossroads between the crossbars there is a threaded hole (12) a toothed disc (4) that has a part with smaller teeth size (1 5) and another with larger teeth (16), where said disc has in its center a hole continued by a bowl (7) in its lower part, which in turn has at its end a part of reduced diameter (1). a thyme (5), threaded bolt or the like, provided with head (14) or similar element of suitable dimensions to seat on the end end of the bowl (7) and of sufficient length to be screwed to the threaded hole (12) of the crosshead (6), leaving its head or end on which it is operated inside the bowl (?), pressing on the final end of reduced diameter (1 7).

The fasteners (1 1) of the crosshead (6) consist of simple screws that thread on respective nuts that are welded to the ends of the crossbars. For the placement of the crosshead, it is enough to introduce it through the register once the door is opened (2) and put it in the desired position, usually about 20 cm below the register. Once in position, with the help of a wrench, the screws are turned until the crosshead is firmly positioned against the inner walls of the lamppost (1).

The crosshead (6) also has a support (10) at the bottom of each crossbar that starts from the crossbar and rests on the inner wall of the lamppost (1). By arranging these supports (10) is the possibility of turning avoided? from! set the transverse plane to the longitudinal axis of the lamppost (1). The length of said supports (10) will depend on! diameter of the lamppost (t), always having to fulfill the condition that making it impossible to turn the assembled assembly, will allow the crosshead to be rotated for positioning during the assembly phase. The crosshead may also have small holes (1 3) in its crossbars for the passage and fastening of the ground conductor of the lamppost (1),

AND! serrated disc (4), ta! and as indicated, it has two differentiated parts, one with small teeth (1 5) (2 to 5 mm from crest to vade) and another with larger teeth (0.5 to 1, 5 was from crest to valley). The cor zone? Toothed teeth will be placed inside the lamppost located as far as possible from the registration door (2).

The disc (4) will also have a pair of stops (9) that prevent its rotation on its own axis when said stops (9) collide with the crossbars of the crúcela (6). Likewise, the disc will also have a fixation (8) that allows its position to be adjusted in the event that its diameter is not completely coincident with the internal diameter of the lamppost (1). For this, said fixation (8) is arranged in the opposite part to the cable passage zone (3), that is, in the part of the disk that will be closest to the register. Said fixing (8) will consist in the same way as in the crosshead (6), in a screw that advances on a nut welded to the bottom of the disc (4).

The assembly procedure of this system is carried out as follows: a) The registration cover (2) of the lamppost (1) is opened and the crosshead (or) is introduced, positioning it horizontally with the help of the supports ( 10). It will then be fixed to the internal walls of the lamppost (I) by means of the fixing screws with the help of a wrench. b) The wiring (3) is passed over the crosshead (6), taking care that this step is carried out by the part closest to the lamp post (2) (1), c) The toothed disc (4) is inserted and the cables (3) are positioned on several of the valleys of the largest teeth (16). The disc (4) is brought to its fine position !, matching the axis of the bowl (7) with that of the hole (12) of the crosshead (6) and providing the largest toothed area (16) as far away possible registration (2). d) Thyme (5) is inserted and threaded into the hole (12) until the head (14) presses on the end of the bowl (17)

Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to broaden its explanation so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essence, it can be put into practice in other embodiments that differ in detail from that indicated as For example, and to which it will also reach the protection that is sought as long as it does not alter, change or modify its fundamental principle.
