FIELD

[0001] The invention relates to a professional locksmith tool and, in particular, to a self-adjusting locksmith tool. The tool can be used in locksmith decoding tools, as well as making sets and kits for the tools, to be used for non-destructive emergency unlocking of locked locks and keyholes.

BACKGROUND

[0002] There are cases where a lock should be legally unlocked, but none of the keys are available, eg when they have all been lost. Normally, in this case, the services of a qualified locksmith are used. Vehicle locks and house locks are in most cases difficult to unlock due to their complexity and high degree of protection against tampering with different types of locksmith tools or against destruction of the lock. In many cases, the orientation of code plates has lately gone from predictable to random, rendering known locksmith tools inapplicable. Thus, since the code plates can be 7-12 or more, the possibilities of their orientation are progressively high, and it is not economically profitable to manufacture a large number of locksmith tools for the same lock model. It also applies to other methods such as the use of anti-decoding cuts at the top and/or bottom of the code plates or at one of their ends. In order to avoid actions that break the lock or door, as well as to shorten the unlock time, different decode unlock devices should be used.

[0003] Many professional locksmith tools are known for non-destructive unlocking of locks, including some French door locks. Some of them are called "probes", which contain a body curved at an angle at one end, the tip of which probes the code pins of the lock and raises each of them individually, until reaching a single turn of the locking tabs of the lock. the lock. It is a laborious and unreliable unlocking, and in some cases also impossible.

[0004] From BG 2371 U1 is known a locksmith decoding tool for vehicles, including a handle and a decoding end piece comprising a pumping element with a round opening at one end and a holder, mounted on the decoding element. bulge, which has round and oblong openings. The carrier contains brackets and perpendicularly located spring bolts, freely mounted in the brackets. The handle comprises a consecutively mounted eddy, an extractor and a power eddy, as the power eddy is connected to the decoder endpiece holder, and the eddy is connected to the decoder endpiece pumping element. In this case, the pumping element is a U-shaped product with a complex wavy profile, which reduces the durability of the product. The tool contains side lifters that bring it into the working position, the bolts are short, and the operation of the tool is complicated. In this known tool, the connection between the eddy and the pumping element of the decoder end piece is direct by means of a screw, which does not allow the eddy to rotate relative to the pumping element, and there is no possibility of rotating the eddy with regarding the extractor. In addition, the bolted joints allow self unrolling.

[0005] In practice, a locksmith decoding tool for vehicles is known, which includes a handle and a decoding end piece comprising a pumping element having a round opening and a holder connected to the pumping element, as well as a carrier having round and oblong openings along its axis, as the handle comprises an axially arranged cup-shaped power swirl with an axial neck on the forehead, a bushing with a threaded opening, the bushing is mounted on its upper end with the possibility of axial and rotary displacement in the cavity of the power vortex, as well as a threaded plug, freely screwed into the threaded opening of the bushing, further comprising an extractor, which is a plug with a smooth cylindrical surface with a board, whose extractor is mounted on the other end of the bushing. The handle also includes a vortex with an opening, in which the lower end with the socket extractor is installed, as well as comprises a cylindrical pusher with a flange, and the pusher located in the opening of the eddy, so it can slide axially in the vortex, while the power vortex, the screw cap and the extractor have a central opening, in which the carrier and the pumping element of the decoder end piece are mounted. This decryption tool has an increased length and weight, making it more cumbersome to handle. It also considerably increases the risk of irreparable mechanical damage and breakage of the tool elements, as well as the lock, which unlocks in case of imprecise handling of the tool.

SUMMARY

[0006] The problem solved by the present invention is to provide a locksmith tool that guarantees comfort in unlocking and operating with car and home locks, provided with security mechanisms, where this locksmith tool has greater reliability and it is easy to handle.

[0007] These and other objectives of the invention are solved by a professional locksmith tool according to claim 1.

[0008] It is a professional locksmith tool including a handle and a decoding end piece, the decoding end piece comprising: a holder having a longitudinal axis and a first and a second end, and openings arranged longitudinally to along the axis at the first end; pins arranged perpendicular to the axis at the second end of the carrier; two pumping elements mounted on the carrier.

[0009] The handle comprises: an axially arranged power vortex in the shape of a cup, a threaded bushing mounted at its upper end in the cavity of the power vortex, a threaded plug loosely screwed to the upper end of the bushing, an extractor mounted on the other end of the bushing and having an axial stop with respect to the bushing, a vortex with a cavity in which the end of the bushing with the extractor is mounted. Along the axis of the handle, axial openings are formed through the power swirl, the screw plug and the extractor, in the openings of which the holder and the pumping elements of the decoder end piece are mounted. The handle also includes a retainer that secures the carrier to the power whirl and passes through a round opening located toward the top (away from the handle) of the carrier, as well as two pivots, the first pivot passing through a second opening. round opening of the carrier and fixed to the screw cap, the second pin passes through a round opening of the respective pumping element and through an oblong opening of the carrier, fixing to the extractor. In this way, an independent rotation of the vortex and the bushing with respect to the extractor can be effected, with an angle of rotation reciprocal to the length of the oblong opening of the holder.

[0010] The bushing with the threaded opening of the handle is located at its upper end directly in the power vortex with the possibility of axial and rotational displacement. The openings at one end along the carrier are arranged successively one oblong and two round openings, and at the other end of the carrier the openings for the pins are transversely provided with coaxial grooves along each opening, while the openings for the pins are made at equal distances from each other, corresponding to the coding plates of the lock. The decode end piece also includes pin holders, each holder has a protrusion which is inserted into the coaxial slot adjacent to the holder's pin opening. Furthermore, the two pumping elements are arranged longitudinally on both sides of the carrier, each of the pumping elements after the round opening successively has two oblong openings arranged in series, so that the round opening of the pumping element corresponds to the oblong opening of the holder and the oblong openings of the pumping elements correspond to the round openings of the holder. Each pumping element has slots, inclined with respect to the height of the pumping element, where the projections of the pin supports enter the slots of the pumping elements. The lateral positioning of the pumping elements also allows the mounting of pins that act in both directions, which solves the problem of the orientation of the code plates imposed by the manufacturers. This, as well as the direct connection of the power vortex to the bushing, eliminates the need for the pusher of known solutions, which simplifies the tool, makes it lighter and increases its resistance.

[0011] The decoder final piece also includes two guides with an angular profile, mounted on the pumping elements in a mirror-like height, while in one arm of each guide several holes for pins are made at one end along the each guide. In the second arm of each guide, at the other end along its length, one oblong and two round openings are successively made from the end, corresponding to the openings of the carrier, and the second arm of each guide is cut on the side from the end with the holes. The guides are fixed, they do not move and, therefore, they improve the carrier making the final piece of decoding more resistant and stable. The shape of the guides is simple and easy to manufacture, they are more resistant to tension and have greater strength. In this case, the pins are located in the middle of the thickness of the carrier and not on the side of the carrier. This allows pressure to be applied to the code plate wall, rather than the code tooth, and helps to overcome the problem of code plate orientation.

[0012] In an embodiment of the invention, the decoding end piece carrier has a double T-shaped profile, the arms of which are made staggered along the height of the profile, so that the upper step of one arm is on the bottom step side of the second arm, the pin openings are made in the vertical beam of the profile along its height, and the oblong round openings are centered through the middle of the vertical beam of the profile. profile. Preferably, the arm with the holes of the angle profile of the guides is located in the upper step of the double T-shaped profile of the carrier and the second arm with the oblong openings of the angle profile of the guides is located on the surface of the elements pumping.

[0013] In another embodiment of the invention, the inclined grooves of the pumping elements have symmetrical counter-inclinations with respect to the height of the pumping elements, the inclined grooves in each pumping element have the same inclination and the number of inclined slots of the two pumping elements is equal to the number of openings of the pins in the carrier. This arrangement also allows pins to be mounted that work in both directions, increasing the possibility of decoding differently oriented code plates.

[0014] In another embodiment, the thread of the cap and the plug have a pitch in the range of 1.5 mm to 8 mm, preferably in the range 2mm to 6mm, and is at least single threaded. In a more preferred embodiment, the thread is metric or trapezoidal or square.

[0015] In another embodiment of the invention, the locking device for fixing the carrier to the power vortex is a slotted cylindrical spring pin. This improves the reliability of the fastening, eliminating the risk of self-unwinding of bolted joints.

[0016] In another embodiment of the invention, at least the power eddy and the eddy are made of engineering plastics. Alternatively, at least the power whirlpool and whirlpool are made of ironwood. These materials are very durable and robust, reduce wear and allow the manufacture of more precise tools, which do not increase production costs.

[0017] The invention also relates to a set of locksmith tools, comprising a toolbox, in which one or more professional locksmith tools of the above-described embodiments are placed, and a plate for resetting the final piece of decoding. Preferably, the locksmith's toolkit also includes a test key for determining the type of locking device. This broadens the scope of the locksmith tool for more types of locks, while allowing for compact storage and preventing accidental damage to locksmith tools and accessories.
