Description

MECHANICAL SECURITY KEY FOR LOCKS OBJECT OF THE INVENTION The present invention, as expressed in the statement of this descriptive memorandum, refers to a mechanical security key for locks, which presents technological innovations in its design in order to increase security against unwanted attempts to open locks. FIELD OF APPLICATION OF THE INVENTION The field of invention corresponds to the auxiliary hardware industry, especially dedicated to security means for locks. BACKGROUND OF THE INVENTION There are different precedents regarding WIPO WO No. 2009 / 135669 A2 describes a key blade with an inserted element that generally has two parts capable of diverting a locking pin. According to the publication, the elements are captured by the blade, are not attached to each other, and do not create a single movable (floating) element. The inventor is unaware of any similar device to the proposed invention that could be considered a noteworthy precedent. DESCRIPTION OF THE INVENTION The embodiments of the present invention are generally related to entry security, and in particular to key sets and lock sets that have elements capable of diverting locking pins and mechanical and design features that considerably increase the number of key / lock combinations, thereby inhibiting unauthorized copying of the key set. Locks are required to provide security by allowing only authorized access to and / or exit from a given entrance. The existence of a locked entrance and / or the inability to open a locked entrance may indicate that unauthorized passage through the entrance is prohibited and / or discourage such unauthorized passage. Locking such entrances can therefore control when, who, and / or what passes through the entrance. Several attempts can be made to gain unauthorized access through a locked entrance. For example, an unauthorized individual might try to enter by breaking the door and / or the lock. However, these actions suffer from many drawbacks, including, for example, the noise associated with breaking the door and / or lock, the resulting visual or audible indication that unauthorized access / exit is occurring or has occurred, the potential need for tools to carry out the act of breaking the door and / or lock, and the time and energy associated with such breaking. Another option for unauthorized entry that may not involve some of the challenges associated with physically breaking the lock or door is to duplicate the key that opens the lock, or to use other devices in an attempt to manipulate or force the lock open. Key duplication for many types of locks simply requires duplicating the overall physical shape of the key blade, recreating the profile of key components and the shape and depth of the holes or cavities in the key. Such an unauthorized copy can be achieved by filing, cutting, and / or working a raw piece of material, such as a blank key or other material that has been machined or can be machined or manipulated to appropriately match the shape and configuration of the key. In addition to allowing entry to authorized individuals, locks for an entrance must have specific key profiles that prevent unauthorized key copying, whether by an unauthorized user or an unauthorized professional who installs the duplicate key. In addition, a variety of high-security institutions require keys with more combinations that are difficult to duplicate in order to prevent unauthorized entry. Modern flat-blade keys often have grooves of varying depths on the key blade or, in the case of high-security entrances, have holes that are of different shapes. In addition, there are keys that come in a variety of shapes, such as round cross-section keys; and keys that have protruding elements; all to prevent unauthorized entry and / or unauthorized key copying. Thus, there is a need for key sets configured to prevent or discourage successful unauthorized copying. Furthermore, there is a need to provide a key set with mechanical properties and design requirements that increase the possible key / lock combinations, thereby limiting successful unauthorized copying and providing enhanced security against unauthorized access or exit through an entry. According to the invention, this security is obtained by means of a conventional key that has a recess in its tip with opposing windows on its narrow faces and is closed at the top by a cap, Inside this housing are two semi-circular pads with a straight inner base so that the semi-circles can come out through the side windows pushed by a common spring to both pads so that when the key is inserted into the lock the pads are hidden inside their recess and when they find a circular surface inside the lock they expand, forming a security element that is difficult to copy. DESCRIPTION OF THE DRAWINGS To complement the description being made and in order to help a better understanding of the characteristics of the invention, two sheets of drawings are attached to this descriptive report as an integral part thereof, in which identical elements are indicated with identical references and where, for illustrative and non-limiting purposes, the following has been represented: FIGURE NO. 1. Perspective view of the key and its component parts. FIGURE NO. 2. Perspective view of the safety tip. FIGURE NO. 3. Top section view of the toe cap with the pads activated FIGURE NO. 4 Top section view of the toe cap with the pads deactivated FIGURE NO. 5 Perspective view of the key inside the lock And in these figures, the same elements are identified with identical numbering: (1) .- head, (2) .- neck, (3) , -palette, (4) . - round cipher, (4) ) .- longitudinal encryption channel, (5) .- lock, (6) .- safety tip, (5) .- support platform, (7) . - boxed, (8) .- strip springs, (9) .- pill, (10) .- lid, (11) .- lid screws, (12) .-windows, (13) .-straight partition, (14) .- lock cylinder PREFERRED EMBODIMENT OF THE INVENTION The device proposed by the invention incorporates novel features in relation to other elements used within the sector and solves problems that until now were difficult to solve. More precisely, the mechanical security key for locks proposed by the invention consists of the following elements: It is a conventional mechanical key consisting of a head (1), neck (2) and paddle (3), on whose paddle (4) the round cipher (4) and a longitudinal cipher channel (4) are visible and at the end the safety tip (6). The safety tip (6) is the novel element of the key, and is made up of a housing (7) with windows (12) opposite each other on its narrow faces and closed at the top by a cap (10) held by four screws (11) at its corners. Within this housing are two pads (9) consisting of two semicircles attached to a straight base (13) so that the semicircles can come out through the side windows (12) pushed by a strip spring (8) common to both pads (9) anchored to their straight partitions (13) which will serve as a brake so that only the semicircular part of the pad comes out. The operation is simple. When the key is at rest, the pads (9) appear through the windows (12). When the key is inserted into the lock (5), the pads slide inwards, and when they reach the cylindrical notch (14) of the lock (5), the spring (8) pushes the pads (9) outwards. Having sufficiently described the nature of the invention, as well as the manner of carrying it out, it should be noted that the provisions indicated above and represented in the attached drawings are subject to detailed modifications as long as they do not alter their fundamental principles, established in the preceding paragraphs and summarized in the following claims.
