    OBJECT OF THE INVENTION
    It is an object of the present invention, as the title of the invention establishes, a device for the automatic unlocking and replacement of the
    10 parachutes of an elevator, also called as a desacuñador. The device can be used to unlock and replace the parachute of both the cabin, the counterweight or the balance mass.
    Characterize the present invention the special construction characteristics
    15 with which it counts, which make it a simple device in its design and easy to use, achieving the purpose of releasing the seizure or blocking of the parachutes on the guides once they have been activated.
    Therefore, the present invention is circumscribed within the scope of
    20 lifting devices and more precisely between the accessories or means of unlocking the parachute of elevators. BACKGROUND OF THE INVENTION
    The parachute systems of the elevators primarily serve to prevent
    25 that the elevator in the event of an event or a damage is of any kind, it does not fall into a vacuum and avoid an accident.
    It is composed of an electric motor and a brake, each element is of the utmost importance for proper operation, and maintenance tasks must be performed periodically. These 30-lift parachute systems constitute the safety of the elevator and work in cases of


    emergency, that is to say when other elements of continuous action and essential for use fail and put the equipment and users at risk.
    When the parachute of an elevator has been activated, the anchoring or braking means, generally wedges, produce a blocking effect of the assembly
    5 The parachute wedges remain on the guides, not allowing movement in any direction, being necessary to have to completely disassemble the parachute in addition to being replaced, an operation that is complex and expensive in time.
    10 Therefore, it is the object of the present invention to develop a device that, when properly assembled and operated, allows to unlock the wedges of a parachute without having to disassemble it, developing a device such as the one described below and which is essentially included in The first claim. DESCRIPTION OF THE INVENTION
    The object of the present invention is a device for unlocking and automatic replacement of the parachute of an elevator, counterweight or mass of
    20 balanced also called as a desacuñador. The device is designed so that the unlocking can move the elevator in any direction, to the counterweight or the balancing mass.
    The parachute must be unlocked in all conditions of
    25 charge to nominal. After the performance of the parachute, the release requires the intervention of competent maintenance personnel.
    The device object of the invention comprises a part for fixing to the guides, and a part for fixing directly or indirectly to the cabin, or
    30 counterweight, both of which are joined by a piece that can be adjusted in length and articulated at its connecting ends to the two fixing pieces, to the guides, and to the fixing to the cabin or counterweight.


    To perform the unlocking, the device is used, being fixed on one side to the guide, and on the other hand, to the chassis - cabin assembly,
    Unless otherwise indicated, all technical and scientific elements used herein have the meaning normally understood by the person skilled in the art to which this invention pertains. In the practice of the present invention procedures and materials similar or equivalent to those described herein can be used.
    Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention. EXPLANATION OF THE FIGURES
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented.
    In Figure 1, we can see a perspective representation of the device object of the invention.
    In Figure 2, we can see a detail of mounting two devices on the side guides of a cabin.
    In figure 3 and 4, each of the above devices and the particular way of acting are shown in detail.


    Figure 5 and Figure 6 show the assembly of the devices for the case of a cabin with the rear guides. 5 PREFERRED EMBODIMENT OF THE INVENTION.
    In view of the figures, a preferred embodiment of the proposed invention is described below.
    10 In Figure 1 we can see that the device object of the invention comprises:
    - a first piece (1) for fixing to the guides
    - a second piece (6) for directly or indirectly fixing to the cabin or counterweight
    15 -a intermediate piece (2) that is joined at its ends in a tilting manner with respect to the first and second pieces, tilting with respect to perpendicular rotation axes, presenting the particularity of being able to regulate its length.
    20 The regulation of the length of the intermediate piece (2) can be carried out by any of the known means, spindle, augers, threaded rod, etc. In the embodiment shown, it comprises a threaded rod (4) provided with a nut (5) or similar welded means which, driven, reduces the length of the intermediate piece (2) and consequently the movement of the
    25 cab or counterweight.
    In figure 1, it is shown how the intermediate piece (2) is connected to the first piece (1) of fixing to the guides by means of an articulation (3), while at its lower end said intermediate piece (2) is joined by way
    30 articulate to the second piece (6) or piece of attachment to the cabin or counterweight by means of an articulation point (7).


    .
    In figure 2 it is shown how the device object of the invention is fixed on one side to the guides (12), while on the other hand it is fixed to brackets (6) or
    5 auxiliary parts that are fixed on the roof of the cabin. This way of fixing the unlocking device is carried out when the guides (12) run laterally to the cabin. In figures 3 and 4 in addition to being able to appreciate the assembly on each of the guides (12), it shows that the drive of the intermediate piece (2) for
    10 to regulate its length is done on the nut (5)
    The fixing means used of the first piece (1) on the guides (12), which are equivalent screws or means (13), are also shown.
    15 In Figures 5 and 6, the fixation of the device to the support structures (14) of the cabin is shown, a situation that occurs when the guides (12) run along the rear face of the cabin.
    Describes sufficiently the nature of the present invention, as well as the
    20 way of putting it into practice, it is noted that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated by way of example, and which will also achieve the protection sought , provided that it does not alter, change or modify its fundamental principle.
