• the support of the invention it is not necessary to change the cylinder of the existing lock or use special cylinders. Likewise, it can be installed in any type of lock regardless of the shape of the profile thereof, such as the European profile, oval profile or round profile. This is due to the fact that the support has a base structure that is fastened on the end of the cylinder of the lock, this base being able to have different shapes without altering the operations of the assembly and as a consequence of this, it can be applied to a wide variety of models without causing large changes in the cost.
• the base structure of the support of the invention consists of a body which is installed on the cylinder of the lock and which acts as a joining element between the lock and the mechanism of the device which performs the opening and closing operations of the lock, such that the fastening is performed through a series of elements arranged in the very support.
• the support for installing opening and closing devices in cylinders of the locks comprises: a base structure configured to receive an opening and closing device, wherein the base structure in turn comprises an opening; a tightening system; fastening elements distributed along the perimeter in the opening; wherein the opening houses an end of the cylinder of the lock and wherein the fastening elements fasten the base structure to the end of the cylinder of the lock by means of a pressure exerted by the tightening system.
• the base structure additionally comprises holes wherein each of said holes is connected to the opening by means of a slot; such that the fastening elements are inserted in said holes which have the same orientation as the opening, enabling the contact between the fastening elements and the end of the cylinder of the lock.
• the fastening elements are selected from the group consisting of: grub screws; threads; knurled screws; spikes; cylindrical parts with grooves on the side surface thereof; and, prismatic parts with side grooves.
• the grooves of the fastening elements have an orientation perpendicular to the generatrix of the cylinder of the lock.
• the tightening system causes the base structure to be deformed by compressing the walls of the opening and the fastening elements, through the side surface thereof, against the surface of the end of the cylinder of the lock, causing the entire support to be immobilised.
• the tightening system consists of two bolts, wherein each of the bolts is threaded to nuts and crosses through holes of the base structure.
• the tightening system consists of two bolts threaded to the base structure, wherein said two bolts cross through holes of the base structure.
• the tightening system consists of a retaining clip situated on the side surface of the base structure.
• the opening of the base structure has a cross section selected from the group consisting of: circular cross section, oval cross section and having a European cylinder profile.
• the support additionally comprises an adapter.
• the adapter is selected from the group consisting of: a key adapter with a slot which fits with at least one portion of the head of the key, an adapter with an internal circular cross section and an adapter with an internal square cross section for cylinder locks having a button of said internal square cross section and internal circular cross section on the inner side thereof.
• the base structure has slots and hollows which facilitate the deformation of the structure when a pressure exerted by the tightening system acts on it.
• the complete immobilisation of the support and the cylinder of the lock is obtained due to the contact made by means of the grooves of the fastening elements, which increases the pressure exerted between the three types of elements (fastening elements, support and cylinder of the lock) when it has less contact surface preventing the support from being able to move or be removed.
• This device is what executes the actions of turning the key starting from a rotor housed on the inside thereof once it receives the order through a remote signal. This device is enabled to turn freely with respect to the support fixed to the lock but the movement thereof in any other direction is prevented.
• the locking and the unlocking can be performed both from the inside and wirelessly from the outside, as well as with a key from the outside if there is a dual clutch or a lock with a cylinder with a button.
