Description

The invention relates to a hand gun consisting of from a handle, a slide, a trigger device with a deduction and a deduction protection. there it can be handguns with serial fire switching option and submachine guns with single action trigger, Double Action, Double Action Only, also in partially stretched Variation, act. With such weapons it comes in particularly fast and easy operation greatest security.

In handguns of this type known from practice is the fuse of the trigger mechanism or the trigger linkage on the side of the rear part of the Grip piece or generally not in the area of the trigger and usually only on one side. That is the quick and easy one Operation detrimental.

From US-A-4 471 551 is a safety device for rifles known that on the firing pin, on the lock and also affects the trigger. With this are vertically movable Securing elements arranged above the trigger device. Because of the multiple function, however, is an off many parts existing and accordingly fault-prone device, the, because of the required height and there typical trigger device, only suitable for rifles. With handguns, there is too great a gap between Handle and barrel axis for tilting the weapon upwards.

From WO-A-95/16179 is a pistol with a trigger safety device known, which has a vertically guided element. Apart from the kinematic, only indirect interaction Securing and deducting is the arrangement of the securing element in front of the trigger guard is impractical because this area when shooting with both hands the index finger of the support hand. With both hands This would result in an inadvertent securing. Unlocking by pushing forward can be ergonomic Reason not with the trigger finger, but only by reaching around the weapon. Besides, it is not possible to Unlock the weapon in a holster as it is inserted would be backed up. So is also this trigger protection of quick and easy operation detrimental and misleading to incorrect operation.

It is therefore an object of the invention to be a simple, reliable and to propose ergonomically correct trigger protection. In particular it is intended for left-handed and right-handed shooters equally good and can be operated with as few steps as possible be well in the hand when shooting.

a) unten einen in gesicherter Stellung mit einer Rast des Abzuges zusammenwirkenden Haken aufweist,

b) in gesicherter Stellung sichtbar vor dem Abzug aus dem Griffstück herausragt,

c) seitliche Vorsprünge aufweist, welche in beiden Stellungen von außen zugänglich sind, und

d) in der gesicherten und in der ungesicherten Stellung von einer federbelasteten Arretierung gegenüber dem Griffstück gehalten wird.

According to the invention, this is achieved in that the trigger lock is formed by a locking element which is essentially vertically movable above the trigger device in the handle, which locking element:

a) below has a hook interacting in a secured position with a catch of the trigger,

b) visibly protrudes from the handle in the secured position before the trigger,

c) has lateral projections which are accessible from the outside in both positions, and

d) is held in the secured and in the unsecured position by a spring-loaded lock relative to the handle.

Because of its mode of action and the resulting shape is the overall height required for the securing element only small, so that the vertical distance between the carriages and trigger device is sufficient. By its arrangement over the trigger can be opened directly using the hook the trigger, regardless of whether it is horizontally movable Slider or as a "tongue" is formed. This is the Device particularly simple, therefore cheap and reliable.

The part of the securing element that protrudes before the trigger not only shows the backup status visible and palpable he also fulfills all ergonomic requirements and allows safe and fast operation. It is covered by mere upward pressure on the trigger finger the lower part of the securing element, whether this is downwards or on both sides sideways in the vicinity of the trigger enough, immediately afterwards the same finger in one obviously operate the trigger in another direction. The lateral projections accessible from the outside in both positions allow the gun with one of two hands back up again. The spring-loaded lock provides the complete assumption of the desired position.

The securing element can be in a vertical guide can be moved in a straight line. It is preferably rocker-like pivotable about an axis arranged transversely to the firing direction (Claim 2). Because of the small stroke required the change in angle was not perceived, but from the ease of movement a swivel bearing benefited.

The lower part of the securing element can be made on both sides protrude the handle, preferably it protrudes in a secured Position before the deduction but downwards (claim 3). This means that when the trigger finger is put on, the shooter immediately feels that the weapon is still secured and there is a particularly short operating distance.

The spring-loaded lock can be in the handle as well also be housed in the fuse element. In a preferred one It consists of one embodiment bolt guided horizontally in the securing element, which in the secured and in the unsecured position each in one Recess engages in the handle (claim 4). Thereby there is no installation space at all.

In a development of the invention, the handle can be upper and have lower stops in the two positions with the lateral projections of the securing element cooperate (claim 5). The side projections can then at the same time the lower part of the securing element form that is visible and accessible for unlocking from the outside is.

If the securing element is rocker-like, comes ease of use if the lower part of the securing element from front to back towards the trigger drops (claim 6). The trigger finger then slides, so to speak over the securing element.

It is ergonomic with the vertically displaceable securing element advantageous if the lower part of the securing element bowl-shaped, openly curved downwards and its edges, facing the barrel muzzle and the trigger, pointed at the edge reach into the fume cupboard (claim 7) or, if the lower part of the securing element is cup-shaped, openly arched downwards and on the one near the muzzle Rounded edge and edge close to the deduction tapering into the fume cupboard (claim 8th). This means that the trigger finger easily finds its way into the safety catch optimal position.

In a particularly advantageous development, the whole Trigger device including trigger guard against the Shot direction inclined downward (claim 9). Thereby not only the horizontal distance between the sledges and trigger device further reduced, which one Counteracting the gun counteracts the shot, but it also becomes ergonomic to the shooter's natural hand position Taken into account, the index finger of the loose shot height hand is pointing slightly downwards.

In Figure 1, the handle is designated 1. Is on it in a known manner, a carriage 2 slidably guided. At the bottom of the handle 1 in the middle is one Trigger device 3 is provided and a general about this Trigger protection designated with 4. For this deduction protection 4 is a vertical shaft 5 inside the handle 1 intended. A trigger guard 6 is part of the handle.

The trigger protection 4 consists essentially of only one Securing element 8. This points in its rear lower Share an extension that forms a hook 9. This Hook 9 engages in the secured position shown in a Rest 11 of the trigger 10, which is a horizontally guided here Slider is a. The securing element forms in front of the hook 9 8 a lower part 12, which may be colored red and in the secured position shown in the trigger area 13 protrudes visibly. But it can also be felt, so that the shooter can recognize the safety status even in the dark can.

The securing element 8 is furthermore provided with lateral projections 15 provided, which are accessible from both sides from the outside. For this purpose, openings not shown in the handle 1 be provided. These openings form lower stops 16 and upper stops 17, the movement of the securing element 8 in the secured and the unsecured Limit position. Inside the fuse element 8 is a pin 18 is guided in a bore not designated, which is pressed out by a spring 19, which in the unlocked position in the recess 20 and in the secured Position in the recess 21 of the handle 1 snaps.

Figure 2 shows the same weapon in the unlocked position. The Securing element 8 is raised so far that the hook 9 the Lock 11 releases and the bolt 18 engages in the recess 20.

In Figure 3, only the securing element 8 'is in a modification shown. Instead of sloping towards the deduction Lower part 12 (FIG. 1) is provided with a shell 30 which the shooter's trigger finger easily finds. ahead and at the back it ends with a sharp edge 31. In Figure 4, the securing element 8 "has a slightly different molded shell 40, the front in a curve 41st merges and has a sharp-edged edge 42 at the rear.

Figure 5 shows an embodiment in which a securing element 50 about an axis 51 arranged transversely to the firing direction is pivotable. Because of the elongated shape of the securing element 50 and the low required stroke results also an approximately vertical movement. The spring-loaded Bolt 54 of the lock is here in a bore 55 recessed in handle 1 and engages in recesses 52, 53 of the securing element 50. The recess 53 corresponds the secured condition of the weapon. With a suitable form of Recesses 52, 53, the bolt 54 ensures that the securing element 50 only in one of the two recesses located and cannot take an intermediate position. The side Projections 56, which are also used to secure the weapon serve and are accessible from the outside are stops 57.58 assigned, which does not correspond to the pivoting movement are parallel.

Figure 6 shows a further variant in which the handle is like this is shaped that between the weft direction 61 and the trigger direction 66 there is an angle 68 of approximately 15 to 25 degrees. A trigger 62 is designed here as a classic "tongue". It can be seen that the handle 60 is shaped in this way is that the existing of trigger 62 and trigger guard 63 Trigger device is inclined downwards by angle 68. Corresponding the grip 60 also has a palm recess 64 and a middle finger recess 65, which also point downwards. This training allows you to casually use the weapon to hold the trigger finger pointing slightly downwards and diminishes also the height distance between the palm and the not shown axis. This allows the weapon do not hit upwards when shooting.

Overall, this makes it a simple and reliable trigger safeguard created and on top of that all ergonomic requirements Taken into account.
