Description

DOUBLE BODY ANTI-THEFT PADLOCK Field of invention

[0001] This application is aimed at the security parts and accessories sector and provides a double-body anti-theft padlock, ideally used as a theft deterrent for buildings, automobiles, bicycles, businesses, and other areas. The anti-theft padlock uses its links to lock metal plates with parallel holes or chains connected at their ends, thus characterizing it as an anti-theft system. Fundamentals of the invention and state of the art

[0002] During the use of conventional padlocks in recent decades, vulnerabilities have been identified that, when exploited, can lead to unlocking. The most common vulnerability is the use of a so-called micha, a term that broadly refers to a master key or lock pick used to operate locks and padlocks.

[0003] Generally performed in two steps, the "mixing" process (in popular jargon) involves fitting two pointed rods together, one with a zigzag shape at its end, which will be inserted into the padlock's combination lock, initiating a repeated in-and-out motion that causes stress on the springs, compressing them. This action is simultaneously followed by tensioning the lock's barrel using the second tool, usually called a cat's claw or tensioner, characterized by being equally pointed but with a 90° bend. e at its end. This shape provides the necessary support so that, when resting on the barrel hole, the index finger can exert force towards the opening, providing the necessary pressure to unlock after aligning the pins with the pick.

[0004] This exercise of picking the lock is the most silent and stealthy way for unlocking, and over the decades, it has been improved with the use of new formats. However, one thing about this operation remains unchanged: Picking has always required the use of two hands. One of them, usually the left, is used to support the tensioner, applying pressure to the barrel, thus waiting for the pins to align. This action is performed by the opposite hand (the right) in the continuous movement of the pick in and out, until the lock is unlocked.

[0005] In the current state of the art, it is possible to find some different padlock models, such as registration numbers BR112020025372-3, PI1101686-8, JP2010510414A, US1890806A and US20150059421 A1, which claim anti-vandal padlocks, padlocks with a single interchangeable rod and conical protection system, padlocks with two locks, click padlocks and locking arrangement, respectively.

[0006] The first registration number BR112020025372-3 (ANTIVANDALISM PADLOCK, OF THE TYPE USED TO ATTACH CHAINS, HARDWARE AND THE LIKE) claims a lower part featuring a pair of transverse screws and an upper part provided with a mechanism to lock, secure and house said transverse screws, said mechanism being defined by a set of radial translation latches actuated by a lock mechanism.

[0007] The second registration number PI1101686-8 (INTERCHANGEABLE SINGLE ROD PADLOCK WITH CONICAL PROTECTION SYSTEM), requires a locking rod (4), a cone body (1) and a padlock body (2) forming the padlock with the option of interchangeability between the locking rods (4) and a conical protection system capable of preventing “blows” from directly hitting the padlock body (2), causing it to break.

[0008] The third record number JP2010510414A (PADLOCK) comprises a lock body (12) responsible for housing a mechanism lock (14), which operates two shackles (20). Rotation of the key cylinder arranged in the lock body with the key opens the first and second shackles.

[0009] Registration number US1890806A (CLICK PADLOCKS) describes a round cylindrical body (1) with shackle holes (2) and (3) and click mechanism, consisting of a plunger (4), rectangular in shape (5), and chamfered in a chisel point at (6), the part (5) sliding in a groove (7) and the spring (6a) normally holding the plunger in position. An operating ring (8) is centrally and rotatably mounted on the cylindrical body and held in position thereon by means of rings or collars (13) and (14), there being a centrally arranged inner flange provided with a number of V-shaped notches or notches (10).

[0010] Finally, registration number US20150059421 A1 (LOCKING ARRANGEMENT) presents a padlock comprised of two bodies (1 and 3), between which is a shackle portion (2). The shackle portion consists of two pins (2A and 2B), and both bodies must be locked to the shackle portion. The padlock can be opened from either side with its keys. In this case, one key may be normally in use and the other key used less frequently.

[0011] Although they describe solutions and functionalities, the prior art does not anticipate the configurations and functions of the inventive step. The complexity of the proposed padlock is evident in the first registration, as it uses numerous mechanical components and relies on a single latch to secure or detach its parts. The other registrations describe their particularities, but none match the configuration of this application, as they all utilize only one body. In the case of registrations JP2010510414A and US1890806A, both adopt a single latch, thus persisting the aforementioned problem of padlock misfiring.

[0012] Registration number US20150059421 A1, despite demonstrating the use of two bodies, does not anticipate the proposal of the present invention because it allows opening from either side using only one key, a function that makes the padlock model easily tampered with. Furthermore, because there are only two locking grooves and no reinforcement, its pins can be easily misplaced, compromising its functionality.

[0013] Considering the recurring problems mentioned, the present invention aims to make available to the market a new arrangement applied to a padlock, bringing a solution with regard to the security of the most varied protection intentions, highlighting, in summary, properties, vehicles, objects, among many other applications dependent on padlocks.

Detailed description of the invention

[0015] According to Figures 1, 2 and 3, the double-body anti-theft padlock (1) comprises two armored bodies (2) and (2') positioned inversely and provided with lower cylinders (3) and (3') moved by keys or secrets, through holes (4) and (4') on one of its sides and rods (5) and (5') on the opposite sides, with intermittent recesses on said rods (5) and (5'). (6) and (6') with conical bases (6.1 ) and (6.1 ') and straight axial interlocking faces (6.2) and (6.2'), opposite to the bases.

[0016] More than one intermittent recess can be made on each rod. (6) and (6') in order to allow for different sizes of spaces (A), (B) and (C) between the armored bodies (2) and (2') (Figures 4, 5 and 6), making the use of the padlock more flexible.

[0017] The new feature of the padlock is the armored bodies (2) and (2') which can have projections (2.1) and (2.1 ') (Figures 7, 8 and 9) in order to increase the area of ​​spaces (A), (B) and (C).

[0018] Another option is to use the interchangeable collars (7) and (7') (Figures 10 and 11) as additional parts instead of the projections (2.1) and (2.1', which can be placed or removed according to the desired use. Fixing the collars (7) and (7') can be made by integrated alien screws (7.1) and (7.1'), which will be pressed onto the surfaces of the rods (5) and (5'), keeping the collars fixed and stabilized. It is possible to adopt only one of the two collars, in this case the collar (7) on the rod (5) (Figure 12) in the double body padlock, meeting the user's need. The material to manufacture the collars can be the same as the rod, in this case stainless steel.

[0019] In a final configuration, collars (7) and (7') can be replaced by collars (8) and (8') with solid steel side ingots (8.1) and (8.1 ') on one or both sides of bodies (2) and (2') (Figures 13 to 16). By using collars (8) and (8') equipped with side ingots (8.1) and (8.1 '), even if one of the smaller rods manages to break, the padlock will not rotate / turn on the other rod, as if it were an axis, since the side faces of the padlocks will be in contact with the face of one of the side ingots, thus preventing its movement.

[0020] It should be noted that the double-body anti-theft padlock (1) will only be opened by turning both keys (9) and (9') simultaneously, even if one of the bodies is damaged, different from conventional standards, patented or not, which can be opened with just one key.

[0021] The double-body anti-theft padlock (1) is characterized by its dynamic configuration and can receive additional accessories to increase the diameter of the rod (vulnerable point for the rebar cutting pliers).

[0022] The need to adjust the shackle diameter is due to the holes in gates and chains that do not accept padlocks with thicker shackles. This allows for use in locations where the holes are smaller, leaving one shackle with a collar / ring and the other without.

[0023] By choosing to use interchangeable collars on the padlock, it is possible to remove them in cases where the link of a certain type of chain cannot pass through the collars, making the padlock flexible and adaptable according to the chosen application, functions that are unavailable in conventional padlocks.

[0024] The main advantage of the double-body padlock is the inhibition of tampering as it consists of two armored bodies and straight rods in a single object, making the work of "picking / mixing" more complex and time-consuming, as the padlock only opens with the simultaneous turning of the keys, causing vandals to give up on violating the object and the protected place or, if they attempt to violate, it is possible to detect the vandalism attempt in time, then triggering the authorities or monitoring companies.

[0025] Other advantages include the possibility of having more application options for the double-body padlock due to the adjustment of the space available between the armored bodies and the ability to use intermittent recesses in conventional padlock hooks, giving them the attribute of increasing or reducing the space between the hook and the armored body.

[0026] It is worth highlighting that the inventive activity in question must be understood as representative and not limitative, capable of undergoing convenient modifications and updates in its form and in the mechanical components mentioned, as long as such modifications do not deviate from the essence of the proposal.
