Description

A method of closing and opening a safety mechanical insert and a pin type safety mechanical insert.

Technical field

The present invention relates to a method for closing and opening a safety mechanical insert, a pin type safety mechanical design, and falls within the field of security technology, in particular for buildings, safes and cars against the intrusion of unwanted persons.

BACKGROUND OF THE INVENTION

To date, various security mechanical inserts have been used to secure the lock mechanism, particularly in rooms, which are bolted to the lock in the transverse center hole below the actuator. These consist of a body in the upper part of which a through hole is formed, interrupted by an external transverse recess for the actuator. On both sides of the through hole, the same rotary lock insert is provided with a longitudinal shaped through hole for the control key, the shape of this opening in both rotary lock inserts being mirrored or respectively. coincident in their mutual mirror location in the body, allowing the use of a single longitudinally shaped control key in both rotatable lock inserts. Vertical recesses down to the outer surface of the operating key are provided in each swivel lock insert, which coaxially extend below the swivel lock insert into the body, where different long and upper locking pins are mounted on the compression spring so that the outer radial shape is inserted. With the correct control key, all the faces of the lower and upper locking pins are pressed precisely to the level of the rotary lock insert, allowing it to be rotated with the control keys in the body, while the combination of the lengths of the lower and upper pins is mirrored even under the second rotary lock insert. identical in their mutual mirror location in the body due to the possibility of using a single common control key for both rotary lock inserts. However, the insertion of the wrong operating key does not move all the faces of the lower and upper locking pins precisely to the level of the rotating locking insert in all recesses of the respective rotary lock insert and the body, so that a portion of the locking pins does not mechanically rotate the rotary lock insert. The two locking inserts are connected via respective transverse recesses to locking tabs which fix them axially in the body and are rotatably mounted in a transverse recess for the body control member. In the transverse recess of the body, an actuating member is loosely and rotatably positioned on one elongated rotary lock insert behind the locking tab, which axially closes and breaks longitudinally shaped through holes for the actuation key of both rotary lock inserts. In the actuating member, above the pivot axis, there is a shaped opening for horizontal latches in both rotary lock inserts which, without inserting the correct control key into the opening of the rotary lock insert, interfere with each other and prevent free rotation of the actuator on the rotary lock insert. After the correct control key has been inserted into any rotary lock insert, the corresponding horizontal pawl is pushed deeper into the actuator bore through the front of the actuator key, and the opposite horizontal pawl of the second rotary lock insert is pulled out of the actuator spring spring. After releasing the lower and upper locking pins in the respective rotary lock insert and in the body with the correct control key, by rotating the rotary lock insert in the body through the respective horizontal latch, the actuator on the rotary lock insert is rotated. Upon removal of the control key in the starting position of the rotary lock insert, the spring-loaded spring latch of the opposite rotary lock insert is released into the actuator bore and the cycle of any rotary lock insert can be repeated by the control key.

A drawback of the current mechanical security inserts is that only one of the half-rotatable locking inserts fitted in the body opening is used with the control key. Since the rotary locking insert has only a short section of vertical recesses with spring-loaded lower and upper locking pins that coaxially extend into the body behind the control key entry, it is possible for an unwanted skilled person to sensitively press all the rotating locking insert on a small length from the longitudinal plate. of the locking insert facing each other of the lower and upper locking pins to the level of the rotating lock insert as the correct control key and then turning the rotary lock insert with the control face to unlock the lock. It is also possible for a thin tool, such as a corresponding longitudinal shape of the operating key or thin foil, to penetrate through the longitudinal opening of the rotary closure for the operating key up to a transversely closed operating member loosely mounted on one rotary insert and damaged by axial impacts. A further disadvantage of the present mechanical inserts is that if the longitudinal opening in the rotary closure for the control key is accidentally clogged, this obstruction of the front of the control key is pushed up to the transversely closed control member, making it impossible to correctly insert the control key into the rotary closure. opening the lock. In this case, it is necessary to either loosen the obstacle with a thin tool from the longitudinal opening of the rotary lock insert or, if this is not possible, mechanically remove the safety mechanical insert from the lock, for example by drilling the body, thereby completely destroying the safety mechanical insert. In addition, current mechanical inserts can be relatively easily overcome by an unwanted person by breaking the body below the transverse central recess in a cross section weakened by the transverse central mounting hole, since the thickness of the recess is large and depends on the radial length of the projection of the actuator. and pushing its rear part behind the lock.

SUMMARY OF THE INVENTION

The aforementioned drawbacks are largely eliminated by the method of closing and opening the safety mechanical insert according to the invention, which consists in that in one direction the release and closing mechanism is simultaneously activated by one engagement of the first control key and the closing mechanism so that the mechanism is secured through in the second direction, only one access to the release first or mechanism is activated by one engagement of the second control key.

In the aforementioned method, there is provided a pivot type safety lock cylinder mechanical lock insert according to the invention, comprising a body with a through hole and an interrupted external transverse recess for the actuator, wherein the through hole in the body is axially fitted with a rotary insert with a longitudinal through hole. for control key. In the swivel insert, there are vertically placed recesses on the outer surface of the operating key, which are aligned with the body and into which the various long lower locking pins are mounted on the compression springs and above the swivel insert the upper locking pins are located. in that the body is fitted on one end with a release rotary insert and on the other side on the end with a lockable rotary insert with at least three pin type combination arrangements, the actuator having at least one radial shaped projection or surface external toothing partially overlaps only the closing rotary and is firmly and releasably connected thereto.

The safety of the mechanical insert is increased by inserting the tangentially flush mounting pin through the actuator into the transverse notch in the closure rotary insert.

It is also an object of the invention that the actuating member is connected to the shut-off rotary insert by a thread. Further, the actuating member is provided with an inner opening. In one embodiment, the inner circular bore has a radial recess. In another embodiment, the inner opening of the actuating member has the same transverse shape as the through opening for the actuating key.

An even higher level of safety is ensured by the fitting of the lock with a revolving swivel insert.

The locking pivot insert and / or the release pivot insert are provided with locking tabs.

The principle of the invention is extended by a feature of the solution, wherein on the second front underside of the body there is a projection with a transverse outer mounting hole, in which the outer pawl fits. Another feature is that the combination arrangement is displaced towards the actuating member, and a transverse outer mounting hole is placed in the lower space of the body thus obtained. Another feature is that the transverse outer mounting hole extends into the bottom of the closure insert. Variation in design is provided by a circular or rectangular or square cross-section of the transverse outer mounting hole. It is also a circular or square or rectangular or key-shaped cross-section of the body, moreover the body is provided on at least one side with a first mounting thread.

An advantage of the invention is a completely new method of closing and opening a safety mechanical insert, wherein two different teeth for a closing rotary and a release rotary insert are formed on virtually the same length of the safety mechanical insert. This method essentially replaces two complete locks as we know them from the prior art. A further advantage of the method is that one key simultaneously activates or deactivates the release and lock mechanisms for one engagement.

An advantage of the invention resides in the construction of the safety mechanical insert. Because the safety mechanical insert comprises twice the number of combination arrangements compared to the prior art, the undesirable person would have to overcome all the locks of the combination arrangements at twice the length.

Since the same longitudinal through hole for the control key is formed along the entire length of the rotary lock insert in the body of the rotary lock insert coaxially positioned, then by inserting the control key into the rotary lock insert opening, the front of the control key moves horizontally and ejects all obstacles from that opening. into it, either accidentally or intentionally unwanted, such obstacles will not affect the proper functioning of the security mechanical lock cylinder. Also, the keyhole in the swivel lock insert and the swivel release liner, prevents damage to the actuator by impacting various tools from the keyhole. By using an actuating member having a toothing on the surface, a reduction in the transverse recess for the actuating member in the body is achieved, thereby increasing the cross-section of the body below the transverse recess and substantially complicating the possibility of forcibly breaking the security lock. In addition, the body of the security mechanical lock cylinder with the rotatable lock cylinder of the invention, even if it is broken by an undesirable person below the transverse central recess, in cross-section weakened by the transverse mounting hole, after removing the front broken part in front of the lock, duplicated in the transverse outer mounting hole either to the lock body or to its fittings.

The safety of the mechanical lock cylinder is increased by the fact that the actuating member is firmly attached to the locking rotary cylinder either by a thread or a pin or by a combination thereof. This secures the lock cylinder against being squeezed out or against the release lock cylinder. In addition, if the actuating member has a transverse panel and only with an opening coinciding with the through hole for the actuating key, the locking rotary insert is secured against being knocked out. This same function is also fulfilled or doubled by the wing lock swivel insert. In addition, in the active position, the wing lock swivel rotates the longitudinal opening 90 ° in cross-section relative to the longitudinal opening of the release swivel insert. This prevents the unwanted person from manipulating the combination arrangements of the shut-off insert.

An even higher degree of safety is ensured by the thread that provides the front edges of the safety mechanical insert body and the fitting mounting hole. After they are screwed together, a very durable compact unit is obtained which can be separated only by boiling an arc or a flame.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

The safety mechanical insert with the pin combination arrangement 5 shown in FIG. 1 consists of a body 1, which in cross section has the shape of a key. The body 1 has a through hole 29 interrupted by its outer transverse recess 31 in its thickened upper portion. The body 1 is provided with a recess 30 in its front portions at the location of the through hole 29. Below the outer through recess 31 there is a transverse central hole 32. The body 1 is provided with five vertical recesses 33 at locations below the release rotary insert 3. Likewise, seven vertical recesses 32 are formed at locations below the lock rotary insert 2. The body 1 described above is shown in Fig. 4. A release liner 3 is axially mounted in the body 1 from the left side into the through hole 29 and a closing insert 2 is axially mounted in the through hole 29 from the right side.

FIG. 7 shows the construction of the release pivot insert 3 and the lock pivot insert 2. Both are cylindrical in shape with a short offset 34 on opposite faces. The release pivot insert 2 and the lock pivot insert 2 both have an axial shaped notch 35 over their entire length that begins on the surface of the roll and ends at about two-thirds of the diameter of the roll as shown in Figures 2 and 3. is provided with five transverse depressions 33 which coaxially coincide with transverse depressions 33 in the body 1 when fitted. The locking rotary insert 2 is provided with seven transverse depressions 22 »which coaxially coincide with transverse depressions 33 in the body 1 in the transverse depressions 33 in the body. 1, compression springs 36 are mounted over which are mounted different long lower locking pins 37 of the same dimensions as the upper locking pins 38 in the vertically located recesses 33 of the two rotary inserts. The assembly consisting of the recess 33 of the compression spring 36, the lower locking pin 37 and the upper locking pin 38 forms a combination arrangement

5. The release pivot insert 2 and the lock pivot insert 2 are provided with locking grooves 39. In addition, the lock pivot insert 2 still has a transverse notch 14.

The inner end of the closure sleeve 2 is rigidly and releasably connected to the actuating member 4 and, as shown in Fig. 1, this connection is realized by a tangentially embedded fastening pin 11 / which fits into a transverse notch 14 in the closure sleeve 2. In addition, adjacent the faces of the release pivot insert 2 and the lock pivot insert 3, a locking tab 10 engaging the locking grooves 39 on the release pivot insert 3 and on the lock pivot insert 2.

The actuator 4 is of cylindrical shape with an inner circular bore 8a with one radial shaped projection 6, as shown in Fig. 9. In this case, the actuating member 4 has a tangential opening 40 for the fixing pin 11. The housing 1 also has a projection 13 with a transverse outer fixing opening 15 of a rectangular shape in the second front underside into which the outer pawl 17 shown in FIG. The outer pawl 17 is inserted into the outer mounting hole 15 in the protrusion 13 of the body 1 via the lateral recess 28 of the fitting.

The safety mechanical insert is fitted with a wing lock rotating insert 2, to which the body 1 is also provided. As can be seen, a radial shaped protrusion 6 projects from behind the body 1, as shown in Fig. 2.

A set of two control keys 41 are associated with a given safety mechanical insert. The first control key 41 has three zones. The first release zone 18 is located at the root 19 of the control key. This is followed by a second neutral zone 20 and finally a third closing zone 21. In this case, the first release zone 18 is provided with a serration of the release code, the second neutral zone 20 is serrated and the third closing zone 21 is serrated with the closing code. The second control key 41 is shorter and contains only a closure code closure, as shown in FIG.

This security mechanical insert is particularly suitable for securing apartments, offices, warehouses, etc. The operation of the safety mechanical insert according to the invention is as follows. Only one of the two different control keys 41 can be used on each side to operate the control member 4. These differ in mirror longitudinal shape and in the reverse arrangement of the radial shaped protrusions in the first zone of the dimensionally longer control key 41. The dimensionally longer control key 41 is intended for actuating the actuator 4 through the release dial 2. The shorter actuating key 41 is only intended to actuate the actuator 4 directly through the shut-off insert 2. Such a safety mechanical insert is therefore positioned oriented, predominantly with the release-liner 3 facing outwards. protected object. In this case, a longer actuation key 41 must be used to control the actuator 4 from the space to the protected object 41, whose radially shaped protrusions of the third closing zone 21 are slid horizontally into the longitudinal opening of the release rotary insert 3 and displaced by its shape. in the release lock insert 3. all faces of the lower and upper lock pins 37,38 exactly to the level of the release lock insert 3 and the release lock insert 3 can be pivoted in the lock mechanical lock body 1 to a vertical position. Subsequently, it is necessary to fully insert the control key 41 into the release pivot insert 2 and into the lock pivot insert 2. If such a control key 41 is dimensionally correct, then its shape will shift all faces of the lower and upper locking pins 37,38 exactly to the level of the release of the rotary insert 3 and the lock rotary insert 2, which enables the release rotary insert 2 and the lock rotary insert 2 to rotate in the body 1. The rotation of the lock rotary insert 2 is then transmitted through the transverse notch 14 in the lock rotary insert 2 and the mounting pin 11 to the actuator 4, by means of its radial projection 6, not shown, the sliding lock of the lock according to the direction of rotation of the control key 41. The actuation of the control member 4 of such a safety mechanical insert from the opposite side is provided by the shorter control key 41 shown in FIG. It is intended only for direct actuation of the actuating member 4 only via the locking rotary insert 2, which is independently mounted in the through bore 29 of the body 1 to the loosely mounted release rotary insert 3. After inserting the correct dimensionally shorter control key 41 into the closing rotary insert 2 by its shape, they move all the faces of the lower and upper locking pins 37.38 exactly to the level of the shut-off sleeve 2, which allows the shut-off sleeve 2 to rotate with the shorter control key 41 in the body, without rotating the opposite swivel release sleeve 3 in the sleeve. The insert 2 in the body and by the shorter control key 41 is then transferred directly through the transverse notch 14 in the shut-off rotary insert 2 and the fixing pin 11 to the actuating member 4 controlling its radial shaped projection 6 turning the shorter control key 41.

The actuation of the control keys 41 from the release rotary insert 3 and the closing rotary insert 2 is carried out in an analogous manner to the insertion in their initial positions.

When the wrong key is inserted into the opening of the shutter sleeve 2 or the release sleeve 1, its surface does not shift all the faces of the lower and upper locking pins 37.38 either in the release sleeve 3 or in the sleeve 2 exactly to the level, Even the upper locking pins 37.38 in the vertical recesses 33 of the body 1 prevent rotation of the locking pivot insert 2 in the body 1, which is not reflected by the movement of the actuating member 4 and the movement of the sliding lock.

Example 2

The safety mechanical insert with the pin combination arrangement 5 provided with the actuating member 4 with its surface external toothing 7 shown in Fig. 11 is preferably mounted in safe locks. For a higher degree of safety, a radial recess 9 and a tangential hole 40 for mounting the fastening pin 11 are formed in the inner bore 8. The highest degree of safety is ensured by the special shape of the inner bore 8 of the actuator 4 so as to coincide with the transverse shape of the bore key 41 as shown in FIG. The safe deposited with the wing body 1 as a lock can advantageously be shown in FIG.

The function and operation is already described in Example 1.

In general, the safety mechanical insert for even higher levels of securing can be provided such that the locking rotary insert 2 at the connection point with the actuating member 4 is provided with a thread 12 as shown in Fig. 8.

For further variations, the outer fastening hole 15 may extend into the through hole 29 of the body. 1 as shown in FIG.

If the safety mechanical insert is to be installed in the apartment door, it is preferred that the body 1 is provided with at least one front side a first mounting thread 16 as shown in Fig. 4. The condition of such a fitting is that also in the fitting the mounting hole is provided with a second mounting thread.

For various variant configurations, the key body 1 may be as shown in Figure 5 or a cylinder shape as shown in Figure 6.

For a further variant, the actuating member 4 with the shaped protrusion 6 can also be provided with an inner opening 8 such that its cross-section coincides with the cross-section of the opening for the actuating key 41.
