The safety plates (4) have serrated edges that define the transition grooves (9) windows (8). Safety plates also display the key's code or The gear of double-sided inserts or blades of the key that defines the password It includes edge portions (10) designed to fit into its edges.

The opening (7) of the lid (3) (and the corresponding opening formed in the bottom of the box) 35802.02 under normal conditions of use, the lock plates (4) for the key are also it defines a passageway foreseen along a transverse direction. Safety As far as the plates (4) are concerned, the key can be inserted under the side portions (10). (alternatively, the safety plates, the key in normal use of the lock may contain slots adapted to cover the conditions).

Generally, the body is for the key in the lock, to go right through the lock. transverse insertion of the safety plates of the key, which are foreseen defines a gateway that defines a free passageway for Safety The projection of the opening (7) in each plane parallel to the plates (4) Defines the through mouth of the switch.

Key opening (7) (or corresponding opening formed in the bottom of the box) When inserted and rotated around its axis, double-sided key blades The toothed edges of the securing plates (4) are in successive contact with the edge portions (10) of the securing plates (4). by making it stand against the movement of the spring means ( l 1) (or under gravity) (Fig. with reference to lie).

Below, the rotation of the key causes the safety plates to lift up. Reference will be made to the location of Figure 1; with this term in general, vertical It means a movement in the direction and upwards. It is slidably mounted, for example, in the box (2) at the location indicated by 12. There is a Bolt element made with a sheet metal plate. Another In other words, the Bolt element (12) is movably mounted on the body. and the key is in the first position in the lock, which corresponds to the unlocked state. by turning the lock between it and a second position corresponding to the closed position. (Figures 3 and 4 correspond to the second position).

Movement of the safety plates (4), especially caused by the rotation of the key, bolt from first position to second position and from second position to first position 35802.02 is substantially perpendicular to the movement of the element (12). Referring to the example shown The movement of the bolt element (12) is horizontal.

Key windows (8) and key double-sided profiles, key rotation, safety plates (4) to the positions where the movement of the bolt element (12) is to be activated. shaped to remove. In other words, the safety plates (4), It is mounted movably on the body and the key is by turning the Bolt element into a position that enables its movement. can be scrolled. In particular, the bolt element protrudes from the windows (8) of the safety plates. it contains a safety pin (13) or “mentonnet”. The key is designed length of the edges or double-sided blades, key for the safety pin (13) which, when turned, defines a free passageway between the outer ends of the windows (8) it makes it possible to align the transition grooves (9) of the safety pins.

In the example shown, each safety plate is rotated sequentially on four key turns. It includes four transition grooves (9) defining the safety pin (13). Safety the number of plates can vary; In the example shown, each key Five security plates are provided, corresponding to five different lengths of the cipher.

In addition, the safety lock (l) is movably mounted on the body. and displacement of at least one safety plate (4) towards the activation position preferably includes an armor (S) which is convertible. Armor (S) slid, switch to let-through position, or where the through-mouth is open (Fig. 3) with the other position that the crossing mouth in question is at least pierced by the armor. occur between at least one blocking location where it is partially blocked (Figure 4). is coming.

Advantageously, the armor is located inside the body, for example inside the box (2).

In general, the armor (S) is the position of the key's passageway, depending on the armor position. adapted to form a growing barrier, for example, the armor (S) is the most at least it has a rather sloping profile (8,). 35802.02 In accordance with the invention, the armor is parallel to the securing plates (4). placed and manipulation as detailed in Figure 2 it is formed together with a barrier plate (14). manipulation blocker The plate (14) is placed parallel to the safety plates (4). in Figure 1 anti-manipulation plate (14), safety plates (4) as shown it is placed in an intermediate position relative to its group; alternatively, manipulation The barrier plate can be positioned in any position relative to the safety plates (4) group. can be placed.

The slots of the anti-manipulation plate (14) are marked with reference number 5 is defined; These are the anti-manipulation plate (14) of the box (2). a pin (6) associated with the box (2) to guide its movement in it. they are adapted to receive, respectively.

Anti-manipulation plate (14), a window (15) with a serrated edge contains. In particular, the window has a sloping profile that defines at least one peak (17). (16) has. In the example shown, two opposing sloping profiles define a peak (17).

The position of the crown (17) is the opening of the safety pin (13) relative to the safety plates (4). refers to its movement, and it corresponds to rising above a groove (9). In particular, the anti-manipulation plate (14) shown in the figure is (13) referring to the opening movement according to the safety plates (4), respectively, in the first and two peaks (17) corresponding to overlapping the third grooves (9). (See the presence of a tamper-proof plate between the two safety plates. illustrated in Figure 5). In the place indicated by 18, the anti-manipulation plate (14) is planar. a displacement wing running perpendicular to its extension, especially a lift wing is indicated. In the figures in the example shown, the manipulation blocker two displacement blades (18) running in opposite directions from the plate (14) is provided. The displacement flap (18) is attached to the tamper-proof plate. (14) extends parallel to at least one safety plate (4) perpendicular to it (Figures 5-8). 35802.02 In addition, the displacement flap (18), for example, of the anti-manipulation plate (14) is placed on its upper edge.

In this way, the safety plate (4) against the action of the displacement blade (18) safety plate (4), anti-manipulation plate (14) drifting along. Safety with particular reference to the example shown when plate (4) is lifted, along the manipulation inhibition plate ('14) is drifting.

Displacement flaps (18) with anti-manipulation plate (14) (armour (S)) It defines the means of restraint between at least one safety plate. Aforementioned restraint means work when switching to the activation position of the safety plate is in condition. For example manipulation with a possible configuration shown in the attached figures at least the first place of the barrier plate (14) and the corresponding armor (S) change (removal) of at least one safety device rather than being generated by the key. It is formed by the displacement (lifting) of the place (4) and this process, with maximum perforation in the tamper-proof plate (14) is taking place.

Referring to the process to be explained later, in Figure 3, the armor (S) and the allow position of the tamper-proof plate (14) is shown (only if the armor (S) and the manipulation inhibition plate (14) The blocking position is not shown due to the action of the plates).

Inclined profile (16), tamper-proof plate (14), eg Bolt the top (17) at the transition between the first position and the second position of the element (12) Bolt element to lift it more than it rests on the safety pin (13) (12), in particular the safety pin (13) (Fig. 4) 35802.02 is adapted.

Advantageously inclined profile (16), Manipulation on Bolt element (12) end of the blocking plate (14) in a support position, for example at the top (17). is melting.

Inclined profile (16) in general conditions, operation of the lock according to the present invention As clarified in the description, the tamper-proof plate is more to a forward blocking position (Figure 4) (preferably further) It defines an adapted shaped profile as follows.

In other words, the shaped profile (16) and the safety pin (13) slewing cam tools working between plate (14) and Bolt element (12) forms.

Referring to the example shown, the anti-manipulation plate (14), the key It includes a passage slot (19) for Advantageously, the through-slot (19) is closed. a profile (P) is restricted.

Preferably, the pass-through slot (19) covers the area of the key pass-through (attach to the safety plates). in a parallel plane) closely following or covering the first or upper difference along a section (1921) and the length (H) of the tamper-proof plate It contains a second or lower part (l9b) with a width that shows it. With the term "height", vertical width of the tamper-proof plate with reference to Fig. 1 or 2; with a reference to Fig. 1 or Z of the tamper-proof plate. or the horizontal dimension in the plane of the plate. In particular, the width of the lower part (l9b) of the housing (19) is smaller than the width of the passage opening (U). from the lower edge of the lower part where it is the same or larger than the width of the passage opening It increases up to the opening that goes into the upper part. In general conditions (19) lower part (1%), the transition in the plane of the tamper-proof plate has at least one size smaller than the corresponding size of the port. 35802.02 The lower part (1%) of the housing (19) is where the tamper-proof plate (14) It limits the part that defines the armor (S).

Anti-manipulation plate for a possible configuration not shown (14), for the switch (open or closed profile), make the area of the switch opening larger a first part that follows or covers in proportion, and a second part that limits the armor It contains a passage opening with a section.

In the case of normal use of the lock, the tamper-proof plate (14) is usually that the upper part (19a) of the slot (19) is aligned with the opening (7) and such a transition extended to follow or cover the mouth closely (Figure 3). placed at height. The manipulation prevention plate (14) plates (4) and possibly also the safety pin (13) lower part (l9b) with opening (7) (Figure 4) so that at least one of the tamper-proof plate in the blocking position, the key-through port is connected to the tamper-proof plate (14) at least partially by the person describing the armor in question. is most anticipated.

Generally shaped profile (16) with safety pin (13), tamper-proof working between the plate (14) and the bolt element (12), the armor (S) at least one further blocking in the future, which is at least partially blocked by It includes slewing cam tools that bring it into position.
