ARTICULATION FOR A BACLE OF A TEAM OF

LIGHTING AND BULK WITH ARTICULATION

DESCRIPTION

Object of the invention

The present invention relates to an articulation for lighting equipment sticks that allows a user to change a damaged luminaire with a simple movement or turn the upper part of the staff without using any auxiliary equipment. The articulation object of the invention is applicable to any lighting equipment in industrial installations.

Technical problem to solve and background of the invention

The change of a luminaire or projector in an industrial area, where the luminaires or the projectors are usually located at great heights, forces the use of auxiliary machinery that entails a high cost or in a simpler way to the use of a ladder to reach the zone where the luminaire or projector is placed, which is the highest zone of the staff, which implies performing work at height and assuming the risk of an accident occurring in the operation of changing the luminaire or projector.

Due to the complication of the task of changing the fluorescents of the luminaires or the bulbs of the projectors, in many cases this task is not performed, which results in an obvious lack of maintenance that has the consequence that there are industrial areas with poor lighting. Poor lighting in turn has consequences for workers or for items stored in these industrial areas, since accidents can occur due to poor lighting and theft can be facilitated by an obvious lack of light. In addition to the above, when in a warehouse, where the storage space and lighting of the stored merchandise are essential, there is continuous traffic of large vehicles that, in many cases, due to changes in the configuration of the storage areas, find luminaries in their path that prevent normal circulation through the interior of the warehouse, turning the luminaire to facilitate the transit of large vehicles is a complex and expensive task, since it involves disassembling the luminaire with its staff and for this task auxiliary machinery is required that also complicates the circulation through the storage area.

In the prior art, document ES 2 349 347 is known, which discloses an elongate member having a first part, a second part and an interconnection means, where the interconnection means are arranged at an acute angle with respect to the first part elongated and the rotation of the second elongated part on the interconnecting means allows a user to access an article located at the upper end of the elongated second part. In the mechanism disclosed in document ES 2 349 347 the lowering of the upper member on the lower is performed in a single movement.

The articulation object of the invention allows two independent movements, a first movement of rotation of the upper section on the lower section and a second movement of folding of the staff.

As already indicated, and as can be seen in the detailed figures, the object of the invention is an articulation (1) for lighting equipment stacks comprising:

a first plate (2) fixed to a lower section of the staff (3),

- a second plate (4) attached to the first plate (2) by means of an axis (5), so that the second plate (4) forms a hinge together with the first plate (2), a third plate (6) ) fixed to an upper section of staff (7), and which also joins the second plate (4). The lower section of the staff (3) in which the joint (1) object of the invention is placed it is fixed in its position attached to the ground by means of a foundation or to a wall by means of clamps or other fixing system, while the upper section of the staff (7) is mobile, being able to only fold down, only turn or both fold and turn, by means of the articulation (1) object of the invention.

The three plates (2, 4, 6) of the joint (1), in the preferred embodiment of the invention, comprise four through holes (8) that are positioned one above the other, to fix the first plate (2) to the second plate (4) and the second plate (4) to the third plate (6) by introducing a pin (9) in each through hole (8). In the preferred embodiment of the joint (1) of the invention, the pin (9) is formed by a screw with a head in which a nut is threaded to fix it in the through hole (8). And in an alternative embodiment the pin (9) is a screw that is threaded into the through holes (8) of the three plates (2, 4, 6). The fixing of the first plate (2) to the lower section of the rod (3) can be done in two ways: a first way is by welding, and a second way is by threading the first plate (2) to the lower section of the rod (3) (this embodiment is not represented in any figure). The same applies to the fixing of the third plate (6) to the upper section of the staff (7), which can be fixed by welding or threading (the fixing by means of a thread is also not represented in any figure).

The first plate (2) comprises two areas of greater thickness (10) that form a housing (1 1) between the two zones of greater thickness (10) and the second plate (4) comprises two recesses (12) and a projection ( 13) between the recesses (12). With the configuration of areas of greater thickness (10), housing (1 1), recesses (12) and projection (13), when the first plate (2) is placed on the second plate (4), the recesses (12) of the second plate (4) coincide with the areas of greater thickness (10) of the first plate (2) and the projection (13) of the second plate (4) is located in the housing (1 1) of the first plate (2).

The shaft (5) that joins the first plate (2) and the second plate (4) passes through the thicker areas (10) of the first plate (2) and through the interior of the projection (13) of the second plate (4). In the preferred embodiment of the invention, the shaft (5) is formed by a main body (17) with two nuts (18) located at the ends of the main body (17) fixing the position of the main body (17) joining the first plate (2) and the second plate (4).

The first plate (2) has a first thickness and the second plate (4) has a second thickness, which may be the same or different. The thickness of the two zones of greater thickness (10) of the first plate (2) is equal to the first thickness of the first plate (2) plus the second thickness of the second plate (4), thus when the second plate (4 ) is placed on the first plate (2) a flat surface appears.

The second plate (4) in addition to the through holes (8) comprises two threaded holes (14) for fixing the third plate (6), since the third plate (6) comprises two guide grooves (15) which are through holes in the shape of an arc of circumference that extend along the third plate (6), where fixing means (19) that cross the third plate (6) are located through the guide grooves (15) and they are threaded into the threaded holes (14) through the second plate (4) but without contacting the first plate (2) since if I contacted the first plate (2) it would damage the surface of said first plate (2) and it would also prevent the correct fixing of the second plate (4) on the first plate (2).

There are two different embodiments for the fixing means (19), a first embodiment in which the fixing means (19) are configured by quick-tightening screws and a second embodiment in which the fixing means (19) are configured by screws with cams. By fixing the third plate (6) on the second plate (4) the upper section of the staff (7) is fixed in a position with respect to the lower section of the staff (3).

The circumferential arc shape together with the extension of the guide grooves (15) along the third plate (6) and the two threaded holes (14) of the second plate (4) guide a rotation movement of the section upper of the staff (7) with respect to the lower section of the staff (3), finally the third plate (6) can be fixed in four different positions that correspond to the four through holes (8) of said third plate (6) allowing fix the upper section of the staff (7) in these same four positions with respect to the lower section of the staff (3).

The guide grooves (15) of the third plate (6) guide the upper section of the staff (7) when the movement to be made is to rotate the upper section of the staff (7) with respect to the lower section of the staff (3), for which the pins (9) are removed from the through holes (8), the fixing means (19) are loosened, the rotation movement of the upper section of the staff is performed ( 7) with respect to the lower section of the staff (3) until the through holes (8) of the three plates (2, 4, 6) coincide again, a fastening of the fixing means (19) is carried out and the insert the pins (9) in the through holes (8) fixing the position of the third plate (6) on the second plate (4) and therefore fixing the upper section of the staff (7) in a new position.

Likewise, what is desired is to reduce the upper section of the staff (7) on the lower section of the staff (3), it is necessary to remove the pins (9) but the fixing means (19) remain unchanged, keeping the third plate (6) to the second plate (4).

The first plate (2) comprises two tabs (16) that extend in a perpendicular direction and then of the thicker areas (10) of the first plate (2), so that in the movement of folding of the upper section of the staff (7) with respect to the lower section of the staff (3), the second plate (4) has a limited movement, since the second plate (4) rests on the tabs (16) of the first plate (2) leaving the upper section of the staff (7) at 90 degrees with respect to the lower section of the staff (3).

The object of the invention is a staff of lighting equipment incorporating the joint (1) previously described. Likewise the object of the invention is a method of folding the staff of a lighting equipment with the disclosed joint, said method comprising the steps:

remove the pins (9) from the through holes (8) located on a first plate (2), a second plate (4) and a third plate (6),
