Description

The present invention relates to a trigger guard for a handgun, especially for a semi-automatic long gun. Furthermore, the invention relates to a handgun with the trigger device according to the invention.

It is known from the prior art to protect firearms, in particular long guns, against accidental actuation of a trigger and firing of the firearm by means of a mechanical safeguard. In addition to handling errors also falls of the firearms or mechanical defects on the weapon can lead to an unwanted triggering of a shot. In addition to the trigger guard, a bar safety device, a percussion lever or firing pin safety device or a combination of these basic variants is used as an alternative. All fuses are based on the fact that special mechanical components are locked in a safety position and / or prevent direct contact with adjacent mechanical components or an assembly. A trigger guard blocked in the safety position via a mechanism the trigger of the firearm. It prevents the tensioned firearm energy transfer from a trigger assembly on a percussion lever assembly to a shot triggering hammer or a firing pin. The energy is provided in a taut state of the firearm by biasing technical springs, such as a trigger spring and a striker spring. The trigger guard consists for example of a safety shaft, which carries a control cam and is rotatable via an actuating lever in two positions. The safety shaft hinders a pivoting movement of a trigger on the trigger in the safety position. The trigger guard is usually designed so that the firearm in the tensioned state, ie with cocked striking lever spring and tensioned trigger spring, can be ge or released. After the gun has been lowered, the trigger lever changes its position and engages with one of its ends in the manner in the control cam that a return movement of the safety shaft in the safety position is no longer possible. Thus, there is an increased risk to people and the environment, for example, by misfired, remaining in the firearm ammunition. It is of interest, for example, in military or pasture use, to provide a weapon safety device that can be moved in a relaxed position weapons in the safety position to then tighten the firearm safely.

The DE 20 2007 004 747 U1 shows a safety device of a firearm with at least one hammer and a striking spring, which is designed as Schlaghebelsicherung. An ignition device is displaceable between a securing position and a firing position. In the safety position, the ignition device is removed from a firing pin so far that no mechanical access is possible. This safety device is intended to enable low-force operation with tensioned and unstressed striker. In this case, a blockage of the mechanism or failure of the safety device can cause the entire firearm is unusable.

From the DE 20 2011 004 556 U1 a trigger device for firearms with a hammer, a trigger and a roller-shaped fuse element of a trigger guard is known. The securing element is rotatably mounted and can be rotated in two positions. In safety position the trigger guard blocks the trigger and in a firing position releases the trigger. A rotatably mounted sear is located between the trigger and hammer and is acted upon by a trigger spring towards hammer blow energetically. The special shape of the trigger lug and its arrangement in the trigger means allow even with severed weapon to move the fuse element in the safety position. However, a disadvantage is a complex installation of additional items on the trigger device, which also lead to an increased risk of failure. A failure of the trigger lug can even lead to the uselessness of the firearm.

The DE 10 2007 004 588 B3 shows a control for a movable about a pivot axis hammer a weapon that can be locked in its clamping position via a locking surface with a mating surface of a trigger element, such as a sear on the trigger lever. At the hammer a cam portion is provided which engages in a deviating from the clamping position pivot position of the hammer on a control surface of the trigger element and this holds in an unlocked position.

From the DE 10 2006 048 436 B4 a trigger device for a firearm, in particular for a self-loading military rifle is known, which comprises a trigger, a trigger connected to the trigger tine part and at least one trigger spring acting on the Abzugsstollenteil. In this trigger device of the trigger finger from the trigger lug part is arranged separately between two stops, one of which prevents the movement of the trigger tongue relative to the trigger lug part forward, the other to the rear. Between The two stops a short movement of the triggering nipple is possible relative to the trigger tiller part.

The DE 1 453 913 A shows a trigger mechanism for automatic and semi-automatic firearms with a arranged between a tension spring and firing positions hammer. A trigger serves to control the working of the hammer. A burst control mechanism serves to fire a burst of fire with a predetermined number of shots on a single actuation of the trigger. The burst control mechanism selectively connects the trigger and hammer to automatically operate the hammer.

From the prior art a variety of solutions for securing a weapon is known. Different types of security show different approaches, which are preferably used depending on the type of firearm. The fuses show an increased installation effort due to additional mechanical parts and an increased risk of defects and failures. Conventional trigger locks with rotatable fuse element show the disadvantage of being unable to be secured in the relaxed state of the weapon and / or to lead to the usability of the weapon in case of failure of the fuse.

The object of the present invention, starting from the prior art is to provide a low-cost trigger guard with low installation costs available, which allows a secure the trigger even in the relaxed state of the weapon and in the event of a defect of the fuse does not lead to firing of the weapon.

The task mentioned, starting from the DE 20 2011 004556U , solved by a trigger safety according to the appended claim 1. The task will continue solved by a handgun according to the attached independent claim 10.

The invention provides a trigger guard for a handgun, especially for a semi-automatic rifle. The trigger guard can be moved from a firing position to a safety position in both a cocked and an unweighted firing position. In this case, the trigger safety device can be attached to a trigger lever pivotable about a trigger axis, which is preferably designed here as a single component and combines parts known from the field of armouring, such as a trigger rod, a trigger blade and a trigger blade. A portion of the trigger corresponding to the trigger bar is aligned in a longitudinal direction of the firearm. If the firearm is in a position of use, a half-moon-shaped trigger tongue connected to the trigger bar is preferably arranged in a known manner below the trigger rod. In this case, the spaced from the trigger rod end of the trigger tongue is aligned in a weft direction. In a taut state of the handgun the safety shaft blocked in the safety position the trigger, while it releases the trigger in the firing position.

In addition to known components, such as a safety shaft which carries a control cam, and an actuating lever for rotating the safety shaft from the safety position to the firing position and back, the trigger safety according to the invention has at least one additional spring-loaded spacer element. In this case, the spacer element is preferably formed by a leg of a leg spring, which preferably has two of the legs. The spacer element is preferably in the longitudinal direction of the trigger on the trigger on. In this case, the spacer element or the leg spring is preferably mounted in the direction of the safety shaft spaced from the take-off axis. Accordingly, the spacer element or the leg spring extends in the direction of the safety shaft and ends between the safety shaft and the trigger lever or behind the safety shaft. While in trigger safety devices known from the prior art, the trigger is in secure weapon position in direct contact with the safety shaft, the spacer element is arranged as a connecting element between the safety shaft and the trigger in the trigger safety invention. The direct contact between the trigger and the safety shaft located in the safety position is not possible, at least in the tensioned state of the handgun. The spacer element is movable at least in the direction of the axis of the safety shaft and can occupy at least two positions dependent on positions of the safety shaft. In this case, the spacer element in the tensioned state of the handgun is preferably not in engagement with the control cam of the safety shaft located in the firing position and the spring force loading the spacer element is preferably minimal.

If the handgun is in the tensioned state and the safety shaft is in its safety position, the spring-loaded spacer element is arranged between the trigger lever and the safety shaft, whereby pivoting of the trigger lever to the safety shaft is blocked. The spacer element compensates for a distance between the safety shaft and the trigger, leaving no Abzugsabstand.

The control cam is formed by at least one at least partially spirally formed recess in the safety shaft. To form the helical nature, the recess has at least one side surface running in the safety shaft, which is inclined with respect to the axis of the safety shaft. This spiral-shaped side surface must extend at least a fraction of a revolution about the axis of the safety shaft; preferably at least one eighth turn, and preferably less than a quarter turn. The spiral shape preferably has the same axis as the safety shaft. In this case, the recess has, for example, at least two depths and, for example, two widths, with a first width merging into a second width and a first depth merging into a second depth. The first depth corresponds to a smaller and the second depth corresponds to a larger shaft diameter of the safety shaft. Adjacent to an axial section of the securing shaft having the recess is an axial section of the securing shaft, which is preferably designed as a solid shaft. By the at least partially spirally formed recess solid shaft sections and portions of the recess are arranged alternately on the safety shaft. At least one of the solid shaft sections is preferably formed at its transition to the spiral-like recess or to the spiral-shaped portion of the recess so that it detects the spacer element when rotating the safety shaft from the firing position to the safety position with relaxed weapon position and displaced axially.

If the firearm is in the tensioned state and in unsecured weapon position, then the safety shaft is in the firing position, so that the recess of the Distance holding element facing. It may be a circumferential portion of the recess, which is not formed spirally. In the tensioned state and in unsecured armed position, a section of the recess preferably faces the spacer element, which has a circular segment-shaped cross section. The firearm is in use, so the recess is preferably located with the first depth and the first width above the spacer element. The trigger is in a first pivot position. In this case, the spacer element compensates only a first part of a distance between the safety shaft and the trigger. There remains at least one trigger distance between the trigger and the backup shaft so that the trigger is pivotable, whereby the handgun is capable of firing.

The handgun is in use position and in tense and secured weapon position, the safety shaft is in the safety position, namely in a rotational position in which preferably one of the full-wave sections is above the spacer element. The trigger is in the first pivot position. The take-off distance between the safety shaft and the spacer element is not present in this state. In this position, the trigger is not swiveled and the handgun secured.

Once a shot is fired with the handgun, it is in relaxed and unsecured weapon position. The trigger is located in a second pivot position, wherein the distance between the trigger and the backup shaft relative to the first pivot position is reduced. The safety shaft is still in the firing position, namely in a rotational position in which the recess is preferably located at the first depth and the first width above the spacer element. In this case, the spacer element compensates only a part of a changed distance between the safety shaft and the trigger. It remains at least the take-off distance between the trigger and the safety shaft, so that the trigger lever is still pivotable.

By changing the backup shaft from its firing position in its securing position, the spacer element is displaced axially relative to the safety shaft in an axial blocking area in the relaxed state of the handgun through the spiral-like recess or by the spiral-shaped peripheral portion of the recess. In the blocking region, the spacer element compensates for a changed distance between the trigger lever and the safety shaft and there is no withdrawal distance, so that a pivoting of the trigger lever to the safety shaft is blocked. During this change from the relaxed unsecured to the relaxed secure weapon position, the trigger lever remains in the second pivot position. In this case, the spacer element is preferably guided in the recess of the first width and the first depth in the second width with the second depth and remains under Federkraftbeaufschlagung in the recess.

In the tensioned state of the handgun a movement of the spacer element relative to the safety shaft located in the locking position from the locking area is released in the direction of the spring force, so that the spacer member moves back from the locking area and blocks pivoting of the trigger to the safety shaft located in its safety position. The trigger takes during the transfer the handgun from the relaxed secure weapon position in the tense secure weapon position again the first pivot position. The distance between the safety shaft and trigger is thus increased. The spacer element then resumes its basic position by virtue of its spring properties, for example by sliding out of the recess of the second width and moving back axially. The spring force causes the spacer element to leave the axial position in the restricted area, in which it has previously been displaced. As a result, it is preferably outside the recess between the solid shaft portion and the trigger. The handgun is safely transferred to the secured tensioned state.

A significant advantage of the trigger guard according to the invention is that the handgun can be brought into a secure state even in severed weapon position. This allows a safe failure of the handgun even in a Zündversagen. It is also advantageous that the handgun remains capable of firing even if the trigger guard is defective.

The spacer element serves to maintain a distance and therefore forms a spacer. The spacer element is preferably formed by a movable leg, wherein a cross section of the leg determines the distance to be held. The cross section of the leg is preferably circular, so that the diameter of the cross section is equal to the distance to be held. The spacer element is preferably pivotable, so that the mobility is formed by a pivoting. The spacer element is preferably pivotable about a first axis and about a second axis perpendicular to the first axis, the first axis being perpendicular to the first axis Axis of the safety shaft and is arranged perpendicular to the extension direction of the trigger lever, while the second axis is arranged parallel to the axis of the safety shaft. The spring-loaded spacer element is loaded by a spring force, which preferably acts only pivoting about the first axis.

Preferably, the spacer element is formed by a spring element.

In preferred embodiments of the trigger guard according to the invention, the spacer element is formed by a leg of a leg spring. In a preferred variant, the leg spring is U-shaped designed with at least two legs. The leg spring can be purchased inexpensively as a standard commercial part. High production costs for special items are not necessary for the execution of the invention. The leg spring is easy to assemble and can be exchanged quickly and easily in case of breakage.

In principle, the at least one spacer element may be part of a spring or be loaded by an additional spring.

The spacer element or the spring element is preferably made of a spring steel wire, a stainless steel wire or a galvanized spring steel wire. Spring materials of this type are among the commercially available spring materials and can be easily taken into account in the selection process.

In a further advantageous embodiment, the safety shaft and the spacer element, based on the Use of the weapon, located above the trigger. In this case, the safety shaft and the spacer element are arranged on the, a beat lever opposite end of the trigger.

The spacer element or the spacer elements are moved axially when changing the backup shaft from its firing position in the securing position by the spiral-shaped recess or by the spiral-shaped portion of the recess over a region of the trigger, which is preferably flat, so that an equal distance from the axis the backup shaft is guaranteed. However, in alternative preferred embodiments, this area of the trigger lever may have different heights, especially in the stopband area.

It is advantageous to arrange the safety shaft at right angles to the longitudinal direction of the trigger. The safety shaft is shorter dimensioned and thus lower weight, and the operating lever is placed close to the handgun, which allows a good handling of the handgun, since no weapons parts protrude from the handgun.

In embodiments in which the spacer elements are formed by the legs of a U-shaped leg spring, the solid shaft portion of the safety shaft is preferably wedge-shaped by the two axially adjacent spiral-shaped recess or by the two spirally formed portions of the recesses. By this shape, a safe entrainment of the two legs is achieved in the axial displacement of the spacer elements.

Particularly preferably, the control cam and the spacer element are each formed in pairs. In this case, the two spacer elements are preferably formed by the two legs of a U-shaped leg spring. The double guide of the two legs secures the function of the trigger guard additionally. The two legs are each by one of the two cams, d. H. passed through one of the two recesses. The cams are preferably mirror-symmetrical to each other. By changing the safety shaft from its firing position in its securing position, the two legs of the U-shaped leg spring against their spring force are preferably apart by the two spirally formed recesses or by the two spirally formed portions of the recesses, d. H. pushed away from each other.

In an advantageous embodiment, the safety shaft made of metal or plastic. Metal designs can be designed to be more wear-resistant, even by suitable surface treatment, while plastic embodiments have a lower weight and can be produced inexpensively, for example by an injection molding process. Depending on the application, the appropriate material can be selected.

The trigger lever of a trigger unit according to the invention may optionally comprise individual components, such as a trigger bar, a trigger sheet and a trigger blade. The withdrawal unit according to the invention is equipped with the trigger safety according to the invention.

In a further embodiment, it has proved to be favorable to design the trigger with at least one hold-down element. The hold-down element secures the position the spacer element on the trigger and prevents the spacer element lifts in an unfavorable position from the trigger. Inasmuch as two of the spacer elements are given as limbs of a U-shaped leg spring, two of the hold-down elements are preferably formed, which are each arranged on one side of the trigger lever.

In another possible embodiment, a tunnel-shaped hold-down may be formed, through which the legs of the U-shaped leg spring are inserted. Such a design ensures the leg position even in the event of breakage of the leg spring. There is thus the possibility that at least one of the two legs of the leg spring remains functional and the handgun continues to be fully functional usable.

The actuating lever is preferably made of a metal or a plastic. Plastic versions have a lower weight and are, as the backup shaft cost, for example by injection molding, produced. Operating levers made of metal are, even by possible suitable surface treatment, wear-resistant than plastic and can have a higher breaking strength. Especially in military use, in which to be expected with rustic environmental and handling conditions, the metal version may be beneficial.

The handgun according to the invention comprises the trigger guard according to the invention, in particular as a component of the trigger unit according to the invention. The handgun according to the invention preferably comprises preferred embodiments of the trigger guard according to the invention. Also, the inventive Handgun prefers such features, which are described in connection with the trigger safety according to the invention. The handgun according to the invention is preferably formed by a semi-automatic long weapon.

Fig. 1 and Fig. 2 show a preferred embodiment of a trigger guard 01 according to the invention for firearms, especially for long guns, with a spacer spring element 02 in a trigger unit 03. Fig. 1 represents the trigger unit 03 in a perspective view. Fig. 2 shows the trigger unit 03 complementary from a side view. The trigger guard 01 shows a safety shaft 04 with an actuating lever 10 with which the safety shaft 04 is rotatable. The operating lever 10 is pivotable between its positions back and forth. The withdrawal unit 03 is shown in a relaxed unsecured weapons position. The safety shaft 04 has two mirror-symmetrically equal-sized control cams 05, which rotate in the form of recesses 11, the safety shaft 04, each with a spirally formed peripheral portion. The control cams 05 rotate mirrored against one another the securing shaft 04. An axial section of the securing shaft 04, which is arranged between the axial sections of the recesses 11, is formed as a solid shaft 12. Each of the two recesses 11 has two depths and two widths.

Fig. 1 and Fig. 2 each further show a trigger 13, which is pivotable about a trigger axis 14, a breaker 19 and a pivotable hammer 20. The trigger 13 is in a first pivot position, which corresponds to the relaxed weapon position. The actuating lever 10 and the safety shaft 04 are in a first rotational position corresponding to the unsecured weapon position, ie a firing position or firing position of the firearm. In use position of the weapon, the safety shaft 04 is above the trigger 13 and the spring element 02. It is arranged transversely to the longitudinal direction of the trigger 13 and is located at the end of the trigger 13, which is opposite to the hammer 20.

The spacer spring element 02, which is formed in this preferred embodiment as a U-shaped leg spring with two spring legs, lies in the longitudinal direction of the trigger 13 on the trigger 13. The spring element 02 is at the end to which the two spring legs are connected, between the trigger 13 and the breaker 19, and spaced in the direction of the securing shaft 04 to the trigger axis 14, pivotally mounted. The other end of the spring element 02 is disposed between the safety shaft 04 and the trigger 13, where it forms a spacer between the safety shaft 04 and the trigger 13. In this illustration, it is in a relaxed spring position. In this position, the safety shaft 04 is a first common portion 21 (shown in FIG Fig. 6 ) of the recesses 11 with a first depth and a first width above the spring element 02nd

The spring legs of the spring element 02 equalize a partial distance between the safety shaft 04 and the trigger 13, wherein the trigger 13 is actuated, since a withdrawal distance remains.

FIG. 3 and FIG. 4 show the trigger unit 03 from the Fig. 1 and 2 in a relaxed and secure weapon position. Fig. 3 shows the trigger unit 03 in a perspective view, while Fig. 4 the withdrawal unit 03 from Fig. 3 additionally shows in a side view. Compared to Fig. 1 and Fig. 2 are the operating lever 10 and the safety shaft 04 in the second rotational position corresponding to the secured weapon position, ie a securing position of the firearm. In this position of the safety shaft 04, the spring legs of the spring element 02 are each in a second section 22 (shown in FIG Fig. 5 ) of the recesses 11, which has a second depth and a second width. The second depth corresponds to a larger diameter of the safety shaft 04 than the diameter of the first depth. The spring element 02 is guided during the rotation of the safety shaft 04 in the recess 11 and displaced in the direction of the trigger lever 13 and in the axial direction relative to the safety shaft 04 in a cocked spring position. The displaced spring element 02 equalizes the distance between the safety shaft 04 and the trigger 13, wherein no withdrawal distance remains. The trigger 13 is thus not pivotable and secured the firearm.

Complementary shows Fig. 7 the trigger unit 03 in a relaxed secure weapon condition and represents the spring element 02 in the axial displacement position, with its spring legs in each case in one of the two second sections 22 (shown in Fig. 5 ) of the recesses 11 sits. Furthermore, in Fig. 7 two hold-down elements 23 are shown, which prevent the spring legs of the spring element 02 from lifting off the trigger 13.

It was in addition to Fig. 5 which shows the two second sections 22 of the recesses 11 in a position of the safety shaft 04, which corresponds to an unsecured weapon position. The operating lever 10 is in the first rotational position.

Fig. 8 shows the trigger unit 03 in cocked and secured weapons position. The trigger 13 is in a second pivot position. The distance between the safety shaft 04 and the trigger 13 is increased compared to the first pivot position of the trigger lever 13 in relaxed weapon condition, whereby the spring legs of the spring element 02 in the direction of their spring force from the second sections 22 (shown in FIG Fig. 5 ) of the recesses 11 could move out and move towards each other. The hammer 20 is in its cocked position. The safety shaft 04 is rotated in the securing position. In use of the firearm, the portion of the solid shaft 12 is above the spring legs of the relaxed spring element 02 and equalizes together with the spring legs of the spring element 02, the distance between the safety shaft 04 and the trigger 13, with no deduction distance remains. The trigger 13 is blocked and can not be operated. The weapon is secured.

Fig. 9 shows the trigger unit 03 in cocked and unlocked weapon position. The trigger 13 is still in the second pivot position. The hammer 20 is located continue in his tense position. The safety shaft 04 is rotated in the firing position.

The recesses 11 are facing the spring element 02 with their first section 21, so that the spring element 02 only compensates for a first part of a distance between the safety shaft 04 and the trigger 13 and a withdrawal distance 15 remains. Thus, the trigger 13 can be pivoted to trigger a shot, whereby the hammer 20 leaves its cocked position.
