    [0002] OBJECT OF THE INVENTION
    [0003]
    [0004] The present invention relates to a support that allows opening and closing devices to be installed on the projection of cylinder locks for doors, only by means of the pressure fixing of its parts, without modifying the state of the door or of the present shield.
    [0005]
    [0006] This support is an external element, depending on the type of profile of the existing cylinder, which presents few limitations for its installation, whose configuration allows it to be located in a variety of locks without altering the components that form them and facilitates the coupling of the device that produces the opening or closing of the door.
    [0007]
    [0008] TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION
    [0009]
    [0010] A wide variety of systems related to the opening or closing of locks for use in access doors of homes or other spaces are known in the current state of the art.
    [0011]
    [0012] This is due to the continuous increase in the implementation of home automation applications in buildings to control the facilities and elements present in homes or offices, facilitating the user's use as well as providing safe access services to interior spaces without the need for opening tools such as keys .
    [0013]
    [0014] One of these domotic door opening installations are the opening and closing devices that are installed inside the doors, in existing locks, allowing the door to be opened and closed from both sides by a remote control or mobile device, issuing a Signal of different technologies such as infrared, bluetooth, radiofrequency or telephone signal, as well as managing access permits, controlling the opening and closing of doors from remote places to your location. These installations may or may not limit the normal operation of the lock, so that it can be opened from the outside with a key without interfering with the opening and closing device or requiring an electronic signal.
    [0015] One of the problems that arise in the use of these opening and closing devices lies in the cylinders present in the locks in which they will be installed. These current cylinders can have double clutch mechanisms, that is, the door can be opened and closed from one side, regardless of whether the key is inserted on the other, cylinders without double clutch, half cylinders or cylinders with a button inside (without key).
    [0016]
    [0017] The opening and closing device is installed by the internal part of the room so that the part of the lock that is outside is not modified, functioning and having a normal lock appearance, being able to open with a conventional key or with any of the assumptions described above.
    [0018]
    [0019] This installation of the opening and closing device consists in placing a support of the device mechanism inside the house. For this, the support can be adapted to the inner key of the lock cylinder, cutting, if necessary depending on the type of device to be installed, part of the head of the key, leaving the part of the key that is housed in the interior of the lock without altering. There are opening and closing devices on the market that do not need the key to be cut and others that require a cut with a specific geometry to fit the mechanism of the opening and closing device. After the installation of the support on the projection of the cylinder and the introduction of the key in the lock, the opening and closing device is coupled on the outside of the support. Another possibility is to adapt, in case of having an inner button cylinder, the support to the axis of said button.
    [0020]
    [0021] In the case of having a cylinder with key opening on both sides, as already indicated, it is necessary that it be double clutch so that it can be opened from the outside, taking into account that inside there will always be a key inserted into the lock. In case of not having a double clutch cylinder, there is no possibility of opening on the outside with a mechanical key, so it must always be done by emitting a signal to the opening and closing device.
    [0022]
    [0023] In the case of installation of supports to locks with cylinders with button inside, the opening on the outside with a key mechanically is always possible since it does not interfere with any internal key.
    [0024] The drawback that arises in these installations lies in the mounting of the support on the lock cylinder, so that it can be placed on the projection that the cylinder leaves with respect to the door or directly on the door surface, which implies having than to drill it to introduce the elements of union between the parts, operation that is not always possible due to the nature of the materials, certifications, aesthetics, robustness of the fixation to the door or other aspects.
    [0025]
    [0026] The current supports present in the market, which do not involve the alteration of the door, require that the cylinder of the lock protrudes from the surface of the door (or of the plate shield and / or the rosette) a minimum distance of 5 mm to be able to perform the static fixing of the support of the opening and closing device, using different tightening methods.
    [0027]
    [0028] In doors where you want to install the opening and closing device, a cylinder that exceeds that minimum distance is not always available, so it is necessary to replace the cylinder of the lock with another one that protrudes that distance. As the cylinder is one of the main parts of the lock, in which safety measures such as anti- dumping, anti-drill, anti-scratch or anti-fouling systems, trained systems, copies of new keys, etc. can be found, changing the cylinder can lead to to a loss of these security measures of the lock in addition to an increase in the cost of installation.
    [0029]
    [0030] In the market there are a range of supports that allow the adaptation of opening or closing devices to regular locks without space limitations or the need to modify the cylinders, but require perforations in the door to ensure the fixing of the mechanism of the opening device and closing, as the collection in FR2933118 in which a sheet of small thickness is placed on the visible surface of the lock, from inside the house, but which is anchored by two screws in the door to be able to support the device mechanism Opening and closing.
    [0031]
    [0032] Other solutions found employ cylinders of specific locks to mount this type of knobs with threaded perpendicular holes to be able to screw on them the support that supports the mechanism of the opening and closing device. This system achieves a direct fix but implies the change of the cylinder of the existing lock, being therefore a more expensive, limiting and complicated logistics management solution.
    [0033] Therefore, the present invention comes to solve two problems that were not solved in the present state of the art such as the possibility of installing supports for opening and closing devices that do not need to alter the state of the door or of the fittings, nor a limited projection space between the cylinder and the door surface greater than or equal to 5 mm (or the plate shield and / or the rosette).
    [0034]
    [0035] DESCRIPTION OF THE INVENTION
    [0036]
    [0037] In order to achieve the objectives and avoid the aforementioned drawbacks, the present invention describes a support that allows opening and closing devices to be installed in cylinder locks that protrude a minimum distance from the door, the plate shield and / or the rosette expanding the range of locks in which to install said opening and closing devices.
    [0038]
    [0039] The support has been configured so that it can be installed from a minimum distance considered of 1.5 mm between the door (or the plate shield and / or the rosette, depending on the type of lock present) and the projection of the cylinder of the lock, improving the range of use of existing brackets.
    [0040]
    [0041] Furthermore, with the support of the invention it is not necessary to change the cylinder of the existing lock or use special cylinders. It can also be installed in any type of lock regardless of the shape of its profile, such as European, oval, or round. This is due to the fact that the support has a base structure that is fixed at the end of the cylinder of the lock, this base being able to have different forms without altering the operation of the assembly and as a result, applied to a great variety of models without incurring Big variations of the cost.
    [0042]
    [0043] The base structure of the support of the invention consists of a body that is installed on the cylinder of the lock and acts as a connecting element between the lock and the mechanism of the device that performs the opening and closing operations of the lock, of so that the fixation is done through a series of elements arranged in the support itself.
    [0044]
    [0045] Therefore, the support for installing opening and closing devices in cylinder locks comprises: a base structure configured to receive a device for opening and closing, where the base structure in turn comprises an opening; a tightening system; fasteners distributed perimeter in the opening; where the opening houses one end of the lock cylinder and where the fixing elements fix the base structure to the end of the lock cylinder by means of a pressure exerted by the clamping system
    [0046]
    [0047] In one embodiment, the base structure additionally comprises holes where each of said holes is communicated with the opening by means of a slot; such that the fixing elements are inserted into said holes that have the same orientation as the opening, allowing contact between the fixing elements and the end of the lock cylinder.
    [0048]
    [0049] The fasteners are selected from the group consisting of: captive screws; threaded threads; knurled ones; some tips; cylindrical pieces with striations on their lateral surface; and, prismatic pieces with lateral striations. The streaks of the fasteners have an orientation perpendicular to the generatrix of the lock cylinder.
    [0050]
    [0051] The tightening system causes deformation of the base structure by compressing the walls of the opening and the fixing elements, through its lateral surface, against the surface of the end of the lock cylinder, causing the complete support to be immobilized.
    [0052]
    [0053] In one embodiment, the tightening system consists of two bolts, where each bolt is threaded to nuts and through holes in the base structure.
    [0054]
    [0055] In another embodiment, the tightening system consists of two bolts threaded to the base structure, where said two bolts pass through holes in the base structure.
    [0056]
    [0057] In another embodiment, the clamping system consists of a clamp located on the lateral surface of the base structure.
    [0058]
    [0059] In one embodiment, the opening of the base structure has a section selected from the group consisting of: circular, oval and of a European cylinder profile.
    [0060] In one embodiment, the support additionally comprises an adapter. The adapter is selected from the group consisting of: a key adapter with a slot that fits at least a part of the head of a key, a circular internal section adapter and a square internal section adapter for cylinder locks with button of said internal square and internal circular sections on the inner side.
    [0061]
    [0062] The base structure has grooves and gaps that facilitate the structure to deform when a pressure exerted by the clamping system acts on it.
    [0063]
    [0064] The complete immobilization of the support and the cylinder of the lock is obtained due to the contact that is made by means of the grooves of the fixing elements, which increases the pressure exerted between the three types of elements (fixing elements, support and cylinder of the lock ) by having less contact surface preventing the support from moving or being removed.
    [0065]
    [0066] This device is the one that executes the actions of turning the key from a rotor housed inside it once it receives the order through a remote signal. This device is capable of turning freely with respect to the support fixed to the lock but its movement in any other direction is prevented.
    [0067]
    [0068] With this configuration, the locking and unlocking can be done both from the inside and from the outside wirelessly as well as with a key from the outside in case of having a double clutch lock or a lock with a button cylinder. The installed device is only visible from inside the enclosure and its appearance on the outside is not altered.
    [0069]
    [0070] BRIEF DESCRIPTION OF THE FIGURES

    [0080]
    [0081] DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    [0082]
    [0083] As can be seen in Figure 1, the support object of the present invention is mainly formed by a base structure (1), which has an opening (1.4) with the shape of the cylinder profile (8) of the lock to be fitted, being said profile selected within the group consisting of circular section (8c), oval (8b) and European profile (8a) as shown in figures 7.3, 7.2 and 7.1 respectively.
    [0084]
    [0085] In addition to this opening (1.4), the base structure (1) in Figure 1 also shows a clamping system consisting of two lateral holes (1.2) so that at one end From each side hole a bolt (7) is inserted to be screwed to a nut (6) inserted by the opposite end of each hole (1.2) although the joint can be made directly to the opposite section or half of the threaded support (1). The tightening of this joint generates the elastic deformation of the base structure (1) favored by vertical grooves (1.1) located in the upper and lower part of the opening (1.4).
    [0086]
    [0087] The support can use other tightening systems instead of the bolts (7), such as a clamp or circular flange located on the perimeter of the base structure (1) that produces the same deformation as the bolts (7) and the same grip on the cylinder of the lock.
    [0088]
    [0089] The deformation generated on the base structure (1) is the cause that the internal surface of the opening (1.4) is compressed on the cylinder of the lock (8) in which it is embedded.
    [0090]
    [0091] In order to obtain a rigid connection between the support and the surface of the lock cylinder that protrudes from the surface of the door (or the plate shield and / or the rosette), the base structure (1) has holes (1.3) located in the same direction and on the perimeter of the opening (1.4), so that they are communicated with the surface of the lock cylinder (8) that is introduced into the opening (1.4). In these holes (1.3) fasteners (5) are inserted with striations or transverse grooves, perpendicular to the generatrices of the profile of the lock cylinder, so that, when compression is performed, by means of the tightening system, the lateral surface of the fasteners (5) comes into contact with the cylinder of the lock (8) exerting a high tightening from the grooves, since by reducing the contact surface, the pressure is higher exerting the same force.
    [0092]
    [0093] Thanks to the arrangement of the grooves of the fixing elements (5) a double clamping is obtained, on the one hand the one that the fixing elements exert (5) against the lock cylinder (8) and on the other hand the one that exert against the base structure (1).
    [0094]
    [0095] Therefore, a firm rigid connection between the parts is achieved even if the distance between the lock cylinder (8) and the surface of the door is very small, as long as they are greater than 1.5 mm.
    [0096]
    [0097] The fixing elements (5) are preferably captive screws, cylindrical pieces of reduced diameter subjected to lathe operations for the generation of the stretch marks on its surface, threaded, knurled threads, tips, or prismatic parts with striations, provided they have a high resistance to deformation to exert tightening on the perimeter surface of the cylinder profile (8).
    [0098]
    [0099] Once the support is mounted and adjusted on the projection of the lock cylinder (8) with respect to the surface of the door, to perform the assembly of the mechanism of the opening and closing device, in the case in which it is a cylinder with key opening on both sides, a key is inserted into the cylinder by the part in which the support has been connected, leaving the head or arc of the key accessible to be attached to an adapter (4), in this case a key adapter (4a), whose configuration allows to absorb the eccentricity of the key when turning in the cylinder, thanks to the dimensions and shape of the internal recess.
    [0100]
    [0101] In case the head of the key is of a size or shape not suitable for insertion into the key adapter (4a), cutting or machining operations can be performed on the neck of the key to make a good adjustment, without manipulate the rest of the components of the set.
    [0102]
    [0103] Once the key is inserted in the cylinder, the key adapter (4a) connected to the head or neck of the key and the mechanism of the opening and closing device coupled on the base structure (1) of the support and the adapter (4), the assembly is completely assembled.
    [0104]
    [0105] For locks with cylinders with a button on the inner side, the adapter (4) used has a hole or hole according to the axis, with a solidary fixing system, which can be of circular internal section (4b) or square internal section (4c ).
    [0106]
    [0107] The present invention should not be limited to the embodiment described herein. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
