Abstract

The two lock parts enclose the trigger unit on either side and are held apart by a toothed link in a plug connection. An insert pin (12) is allocated to one lock part (6). It can engage an insert aperture in the other lock part and can be brought into a lockable, tooth link blocking position. The insert ring is coupled to a handle (33), rotatable w.r.t. one lock part, with the handle forming a support for a combination lock (K). The rotary facility of the handle is pref. lockable. The combination lock may actuate a locking extension (39) of a locking member (38).

Description

The invention relates to a trigger-lock weapon lock, consisting of two lock parts overlapping the trigger unit on both sides, which are held in the way of a plug connection at a distance by tooth engagement, for which purpose a plug pin assigned to one lock part can be inserted into an insertion opening of the other lock part and brought into the lockable tooth engagement position is.

A weapon lock of the type in question is known from US Pat. No. 3,624,945, the one lock part being the carrier of a key-operated lock cylinder. Its cylinder core is coupled with the plug-in pin, which forms a sawtooth-shaped toothing, which toothing interacts with a correspondingly designed, spring-loaded toothed strip protruding into the insertion opening of the other lock part. When the lock cylinder is in the closed position, the toothing and the toothed rack are aligned with one another, so that when the two lock parts are joined together, the toothed rack is deflected in a latching manner. If the locking cylinder is in its open position, the plug is accordingly rotated so that the toothed strip is lifted out over the circular circumferential surface of the plug, but there is still no tooth engagement. This only happens when the cylinder core is turned back into the locking position of the key, while the teeth of the plug pin engage in the toothed strip. Locking and opening the weapon lock therefore always requires the associated key. Furthermore, if the tooth engagement is brought about under high tension, it must be relatively high Forces are applied using the wrench to rotate the spigot out of mesh.

The object of the invention is based on the object of designing a generic weapon lock while maintaining the design which has been proven per se in such a way that handling is simplified.

This object is achieved in a generic weapon lock in that the plug pin is connected to a handle which can be rotated relative to the lock part and which is the carrier of a combination lock.

As a result of such a configuration, a weapon lock of the type in question of simplified handling, which is to be locked off, is specified. No lock cylinder is required to achieve the lockable tooth engagement position and therefore no key, since the handle is the carrier of a combination lock. This can be, for example, a combination lock, the number disks arranged one behind the other on an axis each contain the digits 0-9. After setting the predetermined key secret can be rotated by turning the handle relative to a lock part of the plug pin and disengaged, which position then allows the pulling apart of the two lock parts with release of the trigger of the weapon previously secured by the weapon lock. The longitudinal extent of the handle can be almost as large as that of the one lock part, so that a large lever arm is effective in particular when the handle is eccentrically mounted, so that even with a tight connection of the lock parts, including protective plates made of flexible material, the dissolution of the Tooth engagement position easily achievable is. As a rule, a protective plate is assigned to each lock part. This can consist of rubber or a corresponding plastic. After the two lock parts have been plugged together, it is ensured that at least one lock-side component lies in the path of the trigger and therefore prevents its displacement to trigger a projectile.

An advantageous further development consists in the fact that the rotatability of the handle, which is connected in a rotationally fixed manner to the plug, can be blocked. If the key secret is set correctly, turning the handle always leads to the pin being carried along. If the tooth engagement position is brought about, the handle is locked by adjusting the key secret. Therefore, the plug pin cannot be rotated relative to one of the lock parts. The security brought about by the weapon lock cannot therefore be canceled.

An advantageous feature of the invention is characterized by a locking extension of a locking member which engages in a locking recess of a lock part by actuating the combination lock. If the given key secret is set on the combination lock, the locking member can shift such that its locking extension leaves the locking recess of the one lock part. As a result, the handle is released for rotation while taking the plug with it. If the key secret is adjusted by turning the number disks, the locking extension of the locking member engages in the tooth engagement position by corresponding displacement of the locking member into the locking recess.

According to the invention, it is advantageous that the locking member is designed as a rocker extending in the direction of extension of the handle. The latter, as is common with many combination locks, can interact with the locking sleeves assigned to the combination disks. The latter form flats. If the flats of the locking sleeves are aligned with each other by rotating the number disks, which corresponds to the correct key secret, the locking member rocker can shift so that the locking extension leaves the locking recess of the one lock part. The handle is released for rotation.

The security value of the weapon lock is increased in that the locking member can only be displaced in the locking position of the combination lock. If the handle is rotated from the tooth engagement position into the release position, the locking extension extends above the facing front surface of the one lock part. It is then not possible to turn the number plate because the rocker is then supported on the front surface by the locking extension. A shift of the number discs therefore always requires turning the handle back into the tooth engagement position.

In terms of handling technology, it proves to be advantageous to lock the handle in its two rotary end positions. This locking can be clearly felt and signals both the tooth engagement position and the canceled tooth engagement on the one hand.

Finally, an advantageous feature of the invention is to be seen in the fact that the handle on its longer lever arm, which contains the locking extension, has an outwardly directed nose, which in the lockable End position of the handle passes under a hook projection of the lock part storing it. Therefore, the handle in the area of this lever arm cannot be turned off by the blade of a screwdriver, so that the locking extension of the locking member remains in the locking recess of the one lock part according to the regulations.

According to the illustrated embodiment, a weapon lock 1 designed according to the invention is assigned to the trigger unit 2 of a pistol 3. The trigger unit 2 forms a trigger bracket 5 comprising a trigger 4. It would also be possible to assign the weapon lock to the trigger unit of a rifle.

In detail, the weapon lock 1 is made up of two lock parts that overlap the trigger unit 2 on both sides 6 and 7 together, which extend on both sides of the trigger guard 5, cover the opening formed by this and accordingly make the trigger 4 inaccessible.

One lock part 6 has a cover shell 8, over the edge of which a protective plate 9 made of flexible plastic is inserted. A base plate 10 extends between the bottom of the shell 8 and the protective plate 9, which continues in the same way in a bearing bush 11 for receiving a plug-in pin 12. The latter is positioned eccentrically to the longitudinal axis of the cover shell 8, which is approximately oval in plan. The bearing bush 11 is opened by a tendon-shaped cutout 13. The opening faces the longer side of the oval cover. On the face side, the bearing bush 11 is closed by a bush bottom 11 '.

The plug pin 12 is essentially circular in cross section. Deviating from the circular shape, the plug pin forms a flattened portion, which, however, projects beyond the receptacle 13. On this flattened section, the plug-in pin 12 has a sawtooth-like toothing 14. This interacts with a correspondingly shaped toothing bar 15 which forms saw teeth and is received by the other lock part 7. This forms a congruent counter-cover shell 16 which is configured congruent to the cover shell 8. The edge of its shell is overlapped by a counter-protection plate 17. The one of which has a curved longitudinal edge is equipped with conical elevations 18, which is however state of the art, so that it is not dealt with in more detail here. The bottom of the counter cover shell 16 continues into an insert bushing 19 for receiving the bearing bushing 11 and the plug-in pin 12. Their insertion opening 20 deviates from the circular shape according to a chord-shaped wall 21 and corresponds to the cross-sectional profile of the bearing bush 11 in the region of the recess 13. The toothed strip 15 is guided parallel to the wall. A compression spring 22 loads the toothed rack 15 in the direction of engagement with the toothing 14 of the plug pin 12, see FIG. 4. A cover plate 23 connected to the counter cover shell 16 is used to secure the position of the toothed rack 15 and the compression spring 22.

The base plate 10 supports the protective plate 9 by means of gripping locking bolts 24. These are guided to be displaceable to a limited extent in the outward direction and are acted upon by compression springs 25 in the outward direction. In the exemplary embodiment, six such locking bolts 24 are allocated to the base plate 10. At least one of these locking bolts 24 extends after the weapon lock 1 has been attached in the displacement path of the trigger 4.

The end of the plug-in pin 12 opposite the toothing 14 passes through the cover shell 8 and is equipped there with a coupling projection 26. This contributes to the axial immovability of the plug pin. A locking ring 27 is also provided for this purpose. The latter engages in an annular groove of the plug pin 12 and extends between the base plate 10 and the bottom of the cover shell 8. The coupling projection 26 engages in a form-fitting manner in the bottom 28 of a lock housing S. The latter is approximately box-shaped and forms the two box end walls 29, 30. Furthermore, the box has the two longitudinal walls 31, 32. The lock housing S extends within a knob-shaped handle 33. The latter and the lock housing S are connected to one another by rivets, not shown. A rotary shift the handle 33 is therefore transferred to the plug pin 12 via the lock housing S.

In the upper area, the handle 33 receives an axis 34 supported by the box end walls 29, 30. The bearing cavity 35 in the handle 33 is open on one side. One end of the axis 34 extends as far as this. Three locking sleeves 36, which are arranged one behind the other and which are provided with a flattened portion 36 ', are mounted on the axis 34. The flattened portion 36 'could also be designed as an obtuse-angled recess. This is known, so that it will not be discussed in more detail. The locking sleeves 36 are in a known manner in meshing engagement with the number disks 37 arranged on them. The locking sleeves 36 are taken along by turning them. A compression spring 38 arranged on the axis 34 loads the locking sleeves 36 in the direction of engagement with the number disks 37.

A locking member 38 interacts with the locking sleeves 36. The latter is angular in cross-section and designed as a seesaw. The longer angle leg is spring-loaded by a spring, not shown, in the direction of the locking sleeves 36, while the other angle leg forms a locking extension 39, which extends to the front of the cover shell 8 when the key secret is set correctly. In the tooth engagement position, the locking extension 39 extends opposite to a locking recess 40 in the cover 8 of the one lock part 6, see in particular Fig. 8. The locking extension 39 is located in the longer lever arm of the handle 33, so that the locking recess 40 Cover shell 8 is arranged at a greater distance from the axis of rotation of the plug pin 12. Furthermore, the locking recess 40 is close to one Edge 41 of the cover shell 8, which edge 41 extends approximately over half the circumference of the cover shell 8. The length of the edge 41 is chosen so that the handle 33 can pivot through 90 °. One end of the edge 41 forms a hook projection 42 which, in the tooth engagement position, is passed under by an outwardly directed nose 43 of the handle 33, cf. in particular FIG. 4. In the tooth engagement position, the handle 33 cannot therefore be lifted off with the blade of a screwdriver. to bring the locking extension 39 out of engagement with the locking recess 40.

The cover shell 8 is a carrier of a locking ball 44. The latter interacts with locking recesses 45, 46 of the lock housing S. In the tooth engagement position, the detent ball 44 projects into the detent recess 45. If the handle 33 is rotated by 90 °, the other locking recess 46 interacts with the locking ball 44, which locking positions can be clearly felt.

The following mode of operation occurs: Preferably, the lock parts 6, 7 are assigned to the trigger unit 2 such that the handle 33 is in the longitudinal extent of the cover shell 8 or of the one lock part 6. The lock parts 6, 7, as illustrated in FIG. 11, are now plugged together from both sides of the trigger guard 5, the bearing bush 11 of the one lock part 6 moving into the insertion opening 20 of the other lock part 7. The toothing 14 of the plug pin 12 strikes the teeth of the toothed strip 15, whereby it snaps away. The lock parts 6, 7 are now pressed against each other. The protective plate 9 and the counter-protective plate 17 step against the trigger guard 5. When the lock parts are joined together, they cover the handle opening of the trigger guard from and thus also the trigger 4. It then extends at least one locking pin 24 in the path of the trigger 4, so that manipulations on the trigger are not possible. If the key secret is still set, the rocker-like locking member 38 can be pivoted by rotating at least one of the number disks 37, the locking extension 39 being immersed in the locking recess 40 of the lock part 6 or the cover shell 8 aligned with it. So that the handle 33 is rotatably fixed to the lock part 6 so that no twisting of the plug pin 12 can take place. The tooth engagement position between the plug pin 12 and the toothed rack 15 cannot therefore be canceled.

The tooth engagement connection between the plug pin 12 and the toothed strip 15 can only be canceled by turning the plug pin 12, specifically by means of the handle 33. For this purpose, it is necessary to set the given key secret of the combination lock K by means of the number disks 37. Characterized the locking sleeves 36 are rotated so that the flats 36 'are aligned with each other and allow pivoting of the spring-loaded locking member 38. Along with this, the locking extension 39 leaves the locking recess 40 of the one lock part 6. Now the handle 33 can be turned 90 ° into the position according to FIGS. 2 and 5, the tooth engagement between the plug pin 12 and the toothed strip 15 being eliminated. The two lock parts 6, 7 can now be pulled apart, releasing the trigger unit 2.

The position of the handle 33 rotated by 90 ° latches. In this position, the locking extension extends above the facing front of the cover shell 8. There is such a distance between the locking extension 39 and the front of the cover shell 8 that no adjustment of the number disks 37 can take place, since then the end face of the locking extension 39 abuts the cover shell 8. Rotation of the number disks 37 is only possible when the handle 33 is moved back by 90 °, so that the locking extension 39 and the locking recess 40 are in turn aligned with one another.

Furthermore, provision is made so that the key secret can only be readjusted if the key secret is set correctly, for which purpose the axis 34 is displaced against the spring load via the bearing cavity 35, which is open on one side, against spring loading while removing the tooth engagement between locking sleeves 36 and number disks 37. This is however known prior art. Therefore, it is not discussed in more detail.

Basically, it should be noted that even with very tightly assembled lock parts 6, 7 there is a large lever arm through the handle 33, so that an easy opening of the weapon lock is always guaranteed. Furthermore, no separate key is necessary for this purpose. It is only necessary to set the predetermined key secret by means of the number disks 37.

All the features disclosed are essential to the invention. The disclosure content of the associated / attached priority documents (copy of the prior application) is hereby also included in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
