Description

Insulation closure system.

Field of the Invention

The present invention falls within the field of insulating closure systems, and more specifically, insulating closure systems for access doors to fuses of lighting columns, for the electrical isolation of said columns and that are adaptable to the different thicknesses of lighting column that can be found.

Background of the invention

The lighting columns have, almost entirely, access doors so that a fuse box can be placed inside.

Due to the presence of electrical conductors inside the columns, and the presence of these in public areas makes the isolation of these columns an important issue. Standardized degrees of protection must also be guaranteed to ensure no entry of water or dust, as well as guarantee a certain resistance to impact to avoid vandalism or other accidental impacts.

At present there are isolation systems of the closing system, most of which are based on screws coated with insulators or manufactured entirely with insulating materials such as the one described in patent ES2199720 which discloses a terminal box and fuses with double electrical insulation for joints of lighting posts comprising a box that closes with an articulated lid, along a horizontal axis, which is attached to the box by screws. The problem with this anchoring system is that the door is not flush with the column, with the bad aesthetic effect it produces and the greater ease of being subjected to vandalism. Likewise, it is a complete set of door and fuse box, which makes it not possible to mount a standard fuse box, replacing the entire assembly in case of breakage or malfunction.

Description of the invention

The invention relates to an insulating closure system specifically indicated for fuse box doors of lighting columns comprising:

-

insulating means for fixing the system to the door,

-

at least one L-shaped stop located on the inner side of the door, pivoting on an axis driven by an actuator screw whose head is located on the outer side of the door, attached to the insulating fixing means by means of attachment.

The axis on which the stop pivots is a tubular thread, which comprises a diametral axis located at one of its ends and to which at least one stop is attached, inside which the actuating screw is threaded, both located inside a hollow insulating fixing screw, which acts as a means of fixing the system to the door together with its corresponding insulating fixing nut, the insulating screw head being located, with the head of the actuating screw inside, on the outer side of the door and the nut on the inner side of the door. Thus placing the door between the head of the hollow insulating screw and the insulating nut.

The means of attachment of the insulating nut to the stop is a piece adhered by one of its ends to the insulating fixing nut, and on the other it comprises a perforation through which a screw or the like is introduced, which acts as the axis of rotation of the or the stops, transmitting the movement of the tubular thread to the stopper.

The shaft driven by a drive screw (7) is inside a hollow insulating fixing screw (1) comprising a head, which acts as an external support piece, and two recesses (13) located at the end opposite the screw head. When the actuator screw (7) is rotated, it is threaded by a tubular thread (6) located also inside the hollow insulating screw (1).

The tubular thread (6) comprises a diametral axis (5) that holds the stops (4), moving them on its axis of rotation (8)

located at one of the ends of the stops (4). The stop drag system, therefore, comprises a diametral shaft (5) inserted into a tubular thread metal (6) coated with insulating plastic to achieve electrical insulation, screw operated actuator (7).

On the other hand, the system comprises a connecting piece (14) of the stops (4) to the insulating fixing nut (2), which It is attached, welded or glued to the insulating nut (2), which is fixed to the stops (4) by means of a turning screw (8) which in turn acts as the axis of rotation of said stops (4)

The advantage of this system is the compactness of the assembly because a small linear displacement of the tubular thread (6), produced by the rotation of the actuator screw (7), produces a large displacement of the stops (4).

Mounting stages of the closing system in the lighting column (Figure 4):

-

First, the hollow insulating screw (1) is passed through the door (11) of the fuse box, leaving the head of the hollow insulating fixing screw (1) located on the outside of the door (11) (stage A) .

-

Subsequently, the fixing nut (2) is inserted into the hollow insulating fixing screw (1), which comprises the stop-nut joint piece (14), on the inside of the door, so that the system is fixed to the door, leaving the door between the head of the fixing insulating screw (1) and the insulating fixing nut

(2) (stage B).

-

Next, the actuating screw (1) is inserted inside the hollow insulating fixing screw (1)

(7) the head of said actuator screw (7) being left on the outer side of the door, and a tubular thread (6), 5 open at one of its ends, for threading the actuator screw (7) and on the other comprises a diametral axis

(5)

 of union to the stops (4) (stages C and D).

-Next, the stops (4, 4 ’) are placed (stage E):

or fixing them by one of their ends and by means of a turning screw (8) to the union nut part (14) that is attached to the fixing nut (2).

10 or fixing them to the tubular thread (6) by introducing the diametral axis (5) of the tubular thread (6) into fixing recesses (3, 3 ’) of the stops (4, 4’).

o To prevent the tightening of the stopper turn screw (8) from preventing the correct rotation of the stoppers, a metal bushing (9) is placed as a separator inside the stop-nut connection piece (14), which, at the same time, prevents screw fillets (8) during rotation from affecting the insulating fixing nut (2).

15 o A final stop screw (10) is inserted to hold the two stops together (4, 4 ’).

-

Finally, the door is closed and the actuator screw (7) is turned on the outside of the box, so that the stops move until they reach the illumination column (12), preventing the opening of the door (11 ) (stage F and Figures 1-3).

 2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement D01 is considered the state of the art document closest to the object of the claimed application. Following the wording of independent claim D01 describes the following: Apparatus for sealing composite closure devices, among others, by the following technical elements: - A hollow screw-shaped housing (see reference 30 in figure 2) that crosses the door (see reference D in figure 2; the screw head is on the outside of the door and the body of the door passes through the door towards the inside) and which houses inside an axis (see reference 50 in figure 2) pushed by a spring (see reference 62 in figure 2). -A support stop of the inner part of the door as a latch inserted in the shaft and that rotates in solidarity with it until it comes into contact with the inner part of the door causing it to close (see reference 70 in figures 1 and 2). -An elastic joint and coaxial insulator with the shaft and located between the hollow housing and the stop element (see reference 110 in figure 1). -A retaining nut of the stop element located at the end of the shaft (see reference 71 in figure 2). The stop element mentioned above admits two possible movements (see figures 7 and 8): -Rotation around the hollow housing axis. -Linear (telescopic) movement in the direction of the hollow housing axis. In relation to the independent claim, and taking into account the content of D01, the main difference between R1 and D01 consists in the specific configuration of the stop element and, as a result of this configuration, the movement made by the stop. While in R1 the stop element pivots on an axis driven by a screw until it comes into contact with the inside of the door exerting the necessary pressure to guarantee its closure, in D01 the stop element rotates around the axis of the housing mobile and also moves axially in the direction of the axis of the latter (see page 3, lines 28 to 30) until it comes into contact with the internal part of the door causing it to close. The technical effect derived from this difference has a direct impact on the level of insulation provided by the closure: the insulating means claimed in R1 (screw and nut) attached to the particular movement made by the stop for the closure (pivoting movement on an axis) they provide a level of insulation higher than that provided by the closure described in D01. Therefore, based on the foregoing, the invention claimed in R1 implies an improved effect compared to the prior art. Furthermore, it is not considered obvious that a person skilled in the art obtains the invention claimed in R1 from the content described in D01, therefore the object of the independent claim is considered new in the sense of article 6.1 of the Patent Law and It implies inventive activity. As regards dependent claims numbers 2 to 9, these are considered new and involve inventive activity in the same way as the independent claim upon which they depend. Documents D02 and D03 are representative of the state of the art in the sector. State of the Art Report Page 4/4
