DEVICE FOR ATTACHING A TARGETING DEVICE TO A HAND FIREARM

Description

[0001] The invention relates to a device for attaching a sighting device to a mounting rail of a handgun according to the preamble of claim 1. Handguns, for example sporting pistols or hunting rifles, are widely used in recreational activities. They are also of great importance to law enforcement and armed forces for threat prevention. To aim at a target, known handguns are typically equipped with a rear sight and a front sight. When aiming, the rear and front sights must be aligned to hit the intended target. This type of aiming requires a very high degree of training, as the alignment of the rear and front sights is subject to considerable inaccuracies due to the short barrel of handguns.

[0002] To improve target acquisition when aiming at targets with a handgun, it is known to attach a sighting device to the handgun that replaces the iron sights. These sighting devices, which are additionally attached to the handgun, can be, for example, a red dot sight, a prism sight, or a reflex sight, which are also commonly used on long guns. It is also known from the prior art to mount a handgun on a long gun, as proposed, for example, in US Patent 8,371,056 B1.

[0003] To attach the sighting device to the handgun, devices of this type, often also referred to as mounts, are used. These devices can be fixed to a mounting rail at the barrel end of the handgun's grip and simultaneously allow the attachment of a sighting device available as an accessory. As a result, the sighting device can be selectively attached to the handgun using this device. The known devices for attaching a sighting device to a handgun have the disadvantage that the device must be mounted to the grip using appropriate tools. Due to the necessity of using mounting tools, quick mounting or dismounting of the device, and thus quick attachment or removal of the sighting device from the handgun, is not possible.German patent DE 197 41 753 A1 and US patent 2005 / 0257415 A1 each disclose a mount for handguns that can be attached to an adapter rail on the firearm by means of a clamping device. US patent 2004 / 211105 A1 discloses a mount for handguns with a recess into which the front sight attached to the slide can be received. Furthermore, US patent 8,371,056 B1 discloses a mount whose two mounting jaws can be connected by means of a spring-loaded locking element extending along the direction of fire in order to enclose a Picatinny rail on the handgun and thus form a mounting rail for a sighting device above the barrel of the handgun.

[0004] Furthermore, devices of this type are known that are fixed to the bolt of a handgun. However, this has the significant disadvantage that the devices, along with the bolt, are accelerated very strongly when the handgun is fired, and acceleration forces of several hundred G act upon them. These high acceleration forces render the devices unusable within a short time. Moreover, the movement of the devices along with the bolt when the handgun is fired makes target acquisition by the sights more difficult for the next shot.

[0005] The object of the present invention is therefore to propose a new device for attaching a aiming device to a handgun, which can be mounted by hand in a short time without mounting tools and, if necessary, dismounted again.

[0006] This problem is solved by a device according to the teaching of claim 1.

[0007] Advantageous embodiments of the invention are the subject of the dependent claims.

[0008] The device according to the invention is based on the fundamental idea that the clamping device for fixing the device to the grip of the handgun has a clamping jaw that is movably mounted on an actuating device. The clamping jaw can be adjusted between an open position and a clamping position by means of the actuating device. In the open position, the clamping jaw does not rest against the outside of the grip, so that the device can be easily slid onto or off the mounting rail on the grip of the handgun. When, on the other hand, the clamping jaw is in its clamping position, it rests against the mounting rail of the grip and frictionally secures the device in the respective position. No tools are required to adjust the clamping device between the open and clamping positions, so that very quick assembly and disassembly are possible.Disassembly of the device on the handgun is made possible.

[0009] The clamping jaw secures the device in its clamped position based on friction between the jaw and the grip. The resulting holding forces depend on a variety of factors. In particular, the surface properties of the grip can lead to an undesirable deviation of the holding force from the required minimum. To ensure reliable fixation of the device to the handgun at all times, a locking element is incorporated into the clamping mechanism. This locking element engages positively with a corresponding notch on the grip of the handgun when the clamping jaw is in its clamped position, thus preventing the device from being subsequently removed. Only by deliberately disengaging the locking element can the clamping device be released and the device removed from the handgun.To ensure a secure fit of the device on the handle, the actuating mechanism includes a tension spring that pre-tensions the clamping jaw in the clamping position. The actuating mechanism features a manual actuating element, designed as a push button, which compresses the tension spring and moves the clamping jaw from the clamping position to the open position against the spring force. To easily transmit the actuating force from the push button to the clamping jaw, a push rod is attached to the push button. This push rod runs, for example, beneath the handle through the device, so that pressing the push button lifts and releases the clamping jaw.For simple and cost-effective manufacturing, it is advantageous that the locking element for the positive-locking attachment of the device to the handle is integrally integrated into the push rod. Furthermore, it is particularly advantageous if the clamping jaw is fastened to the end of the push rod with a fixing screw.

[0010] To facilitate particularly convenient and rapid mounting of the device on the handgun, a preferred embodiment provides for an insertion ramp on the clamping jaw and / or the locking element. When the device's base body is slid onto the mounting rail, this insertion ramp engages at the end of one of the two prismatic longitudinal edges of the mounting rail, thereby pressing the clamping device into its open position without any user intervention. In this open position, the device can then be easily slid onto the mounting rail.

[0011] Even after the device is attached to the handgun, it is necessary that the slide remains movable to allow for ejection of the spent cartridge and reloading. During this slide movement, the front sight is moved several centimeters rearward. To prevent the front sight from colliding with the device's components, the upper part of the device's base, which faces the top of the slide, may have a corresponding recess. This recess in the base must be positioned so that the front sight can be engaged in it when the slide is retracted, thus preventing a collision between the base and the front sight.

[0012] To position the aiming device as close as possible to the user's eye, it is particularly advantageous if both side parts of the base body have a bend. This allows the underside of the base body to be fixed relatively far forward on the grip, while simultaneously enabling the aiming device, mounted on the top of the base body, to be positioned further back. To allow the attachment of additional accessories to the handgun alongside the aiming device, it is particularly advantageous to have an adapter on the lower part of the base body, opposite the underside of the grip. Additional parts, especially illumination devices, can then be attached to this adapter.

[0013] The material from which the device is made is essentially arbitrary. To achieve a particularly light weight, it is advantageous if the main body of the device is made from a single piece of aluminum or plastic.

[0014] One embodiment of the invention is shown schematically in the drawings and is explained below by way of example.

[0015] They show: Fig. 1 a device according to the invention for mounting on a handgun in a perspective side view; Fig. 2 the device according to Fig. 1 in a first side view; Fig. 3 the device according to Fig. 1 in a second side view; Fig. 4 the device according to Fig. 1 Front view; Fig. 5 the device according to Fig. 1 after disassembly of the handgun; Fig. 6 the device according to Fig. 1 in a first perspective side view; Fig. 7 the device according to Fig. 1 in a second perspective side view; Fig. 8 the device according to Fig. 1 in a third perspective side view; Fig. 9 the device according to Fig. 1 in an exploded view; Fig. 10 the device according to Fig. 9 in an exploded view from above.

[0016] Fig. 1 Figure 1 shows a device 01 attached to a handgun 02, which carries a sighting device 03, namely a red dot sight. The handgun 02 comprises a grip 04, a barrel 05, and a slide 06.

[0017] Fig. 2 Figure 2 shows the handgun 02 of the device 01 in a side view. To attach the device 01 to the grip 04 of the handgun, a mounting rail 07 is provided at the barrel-side end of the grip 04, comprising two prismatic longitudinal edges 08 on both sides of the grip 04. The base body 09 of the device 01 is slid onto these two prismatic longitudinal edges 08 from the front. Due to the positive fit between the base body 09 and the mounting rail 07, the device 01 thus retains only one degree of freedom of movement, namely in the longitudinal direction of the barrel 05.

[0018] Fig. 3 Figure 2 shows the handgun 02 with the device 01 from the opposite side. On this side of the device 01, a clamping jaw 10 is visible, which is guided in a recess of the base body. The inner side of the clamping jaw 10 can be adjusted between a clamping position and an open position by means of an actuating device, whereby the clamping jaw 10 engages frictionally on one of the two prismatic longitudinal edges 08 in the clamping position.

[0019] Fig. 4 Figure 2 shows the handgun 02 with the device 01 in a front view. A push button 11 is visible, which is part of an actuating mechanism for actuating the clamping jaw 10. When the user presses the push button 11, the clamping jaw 10 is moved from its clamping position to the open position, so that the device 01 can be pulled off or slid onto the mounting rail 07.

[0020] Fig. 5 The device 01 is shown after disassembly of the handgun 02 and the aiming device 03.

[0021] Fig. 6 Figure 1 shows the disassembled device 01 with the aiming device 03 mounted on the top of the base body 09. The inside of the clamping jaw 10 for frictionally fixing the device 01 to the handle 04 is visible. A push rod 12, which is laterally displaceable within the base body 09 of the device 01, serves to transmit the actuating force from the push button 11 to the clamping jaw 10. A detent element 13 is integrally formed on the side of the clamping jaw 10 with the push rod 12. This detent element 13 can engage with a projection 14 in a detent contour 15 (see Figure 1). Fig. 5 ) engage on the underside of the grip 04 of the handgun 02. As soon as the locking element 13 is engaged, the device 01 is secured to the grip 04 in two ways: firstly by the clamping jaw 10, which engages the grip 04 by friction, and secondly by the locking element 13, which engages positively in the locking contour 15 on the grip 04.

[0022] Fig. 7 Figure 1 shows the device 01 in a second perspective view. It can be seen that the clamping jaw 10 is fixed to the end of the push rod 12 by means of a fastening screw 16.

[0023] Fig. 8 Figure 1 shows the device 01 in a perspective view from below. A slot-shaped recess 17 can be seen on the upper part 18 of the base body 09, in which the grain 19 (see Figure 2) is placed. Fig. 1 ) of the handgun 02 can be picked up during the recoil of the slide 06 in order to prevent a collision between the front sight 19 and the body 09. An adapter device 21 is provided on the lower part 20 of the body 09, to which further accessories, for example a lighting device, can be attached if required.

[0024] Fig. 9 Figure 1 shows an exploded view of the device 01. The actuating device, formed from the push rod 12 and the push button 11, for actuating the clamping jaw 10 is pre-tensioned with a tension spring 22 in order to press the clamping jaw 10 against the longitudinal edges 08 on the handle 04 with the corresponding pre-tension force.

[0025] Fig. 10Figure 1 shows an exploded view of the device 01 from above. A guide chamfer 23 can be seen on the clamping jaw 10, which, when the device 01 is slid onto the handle 04, causes the clamping jaw 10 to come into contact with the front end of one of the two longitudinal edges, thereby pulling the clamping jaw 10 into its open position.
