WO1997028414A1 - Hand gun with an ergonomic grip part - Google Patents

Abstract

The grip part (1) of a hand gun should have an anatomically favourable design which makes the handgun more comfortable to hold and easier to use, and the gun recoil more easy to control. For that purpose, the trigger area (4) with the trigger finger (5) and the trigger guard (6) is inclined downwards at an angle (11), the rear side of the handgrip (3) has a recess (22), both sides in the upper area have a hollow (24) approximately as long as a thumb, and a bead-like projection (27) is arranged at the front side at about one middle finger breadth below the trigger guard (6).

Description

 FIREARMS WITH ERGONOMIC HANDLE

The invention relates to a handgun with a grip that has a grip area, in front of it a trigger area with trigger lever and trigger protection and above a straight guideway for a barrel, trigger lever and trigger protection determine the direction of the trigger trigger finger.

Such pistols place particularly high demands on handiness, operational reliability and accuracy. Their satisfaction requires careful study not only of the ergonomic conditions (hand position, muscle tension, fatigue) when shooting, but also of the shooter's previous movements; especially in the instinctive defense shot (German shot) that occurs in police and military operations. In order to tire the hand as little as possible, the tilting moment exerted by the recoil of the weapon on the hand should be as small as possible. In addition, government weapons are serial products that cannot be individually adjusted.

A generic weapon is described, for example, in DE 30 00 017 AI. The grip piece there consists of a frame which has a conventional grip shell in the grip area and a trigger area in front of the grip shell, the general direction of which is inclined upward towards the guideway.

With this and other previously known anatomical shapes in the grip area, there is not sufficient hold for the Given fingers of the shot or support hand. There is also lateral tensioning of the trigger finger. In addition, the roughening in places in the grip area is far from sufficient to achieve the desired effect, or they are arranged out of place or only poorly shaped.

FR 2 386 011 A describes a sports weapon, the handle of which is molded onto the hand of a particular shooter for competition shooting. This handle design is unsuitable for practical use because it makes the aforementioned previous movement sequences very difficult. In particular, the front and the back of the grip area should run essentially parallel in order to achieve a constant grip angle. The shape on the front of the handle above the spur, due to its essentially straight downward shape, causes the middle finger of the shot hand to be pressed down, which has a negative impact on the comfort and recoil behavior of the weapon.

The aim of the invention is therefore to design the handle as a whole and in particular the handle area, anatomically more favorable, with good holding comfort, with better control of the weapon recoil and with better usability under time pressure. The weapon should fit into any hand (including that of a left-handed shooter) and should have a pleasing shape.

According to the invention this is achieved in that the trigger area with trigger lever and trigger guard determine a direction which is inclined at an angle downward with respect to the guideway.

This gives two advantages. On the one hand, the shooter's trigger finger can be caused by the direction of the trigger and trigger protection in a slightly downward pointing tion remain, whereby the trigger finger does not suffer any lateral tension. On the other hand, the force vector of the recoil thereby runs very close to the hand, as a result of which the tilting moment remains very small; nevertheless there is enough space further ahead between the guideway and the trigger device for the trigger mechanism and for safety devices. This angle preferably moves between 5 and 15 degrees (claim 2).

In a further development of the invention, the four sides of the handle area are shaped as follows (claim 3):

a) the rear side has a depression (22) of approximately half a finger's width in the upper region, b) both sides have an approximately thumb-long depression in the upper region which adjoins the depression and is approximately thumb-wide and the lower slope of which lower grip area rises, c) at the front (2) a wall-like elevation is set about a middle finger width under the trigger guard.

The recess on the back improves the support and positioning of the ball of the thumb of the shot hand. The thumb-shaped depressions adjoining on both sides serve to take up the thumb and the finger root of the shooting hand, regardless of whether it is the right or the left, and allow an emotional and reproducible adjustment of the elevation. The wall-like elevation serves to support the middle finger of the shot hand. The middle finger connects directly to the trigger guard and is not deflected downwards by the trigger finger. Thus there is no lateral tension between these two fingers.

Furthermore, the wall-like elevation prevents the middle finger from being pressed down, which would impair holding comfort and recoil behavior. The formation of further wall-like elevations for the remaining fingers would not be expedient because their shape varies too much individually. Overall, these three features serve to protect the hand and ensure accuracy.

In a preferred embodiment of the invention, the entire grip area is essentially roughened (claim 4), whereby the weapon hold is generally decisively optimized and does not subside even when the hand is tired.

In a further development of the invention, a magazine holding button to be actuated on both sides looks out essentially at the height of the trigger and outside the thumb-length recess (claim 5). The magazine holding button to be operated on both sides is thus arranged in the raised part of the handle piece. It can be operated from the left as well as from the right, making it equally accessible for left-handed and right-handed shooters. As a result, the unintentional actuation of the magazine holding button by the middle finger or thumb of the shooting hand is prevented.

In a further development, the grip piece has lateral indentations on both sides of the entire trigger device, in which an actuating member of a safety unit emerges on both sides (claim 6). The trigger protection unit per se is the subject of the Austrian patent application A 2014/95, in cooperation with the invention this on the one hand causes the index finger to intervene more rapidly in the trigger area and on the other hand the trigger trigger unit is actuated quickly.

It is within the scope of the invention that the front part of the trigger guard has a roughened surface on the outside (claim 7). The roughened surface serves to support the index finger of the support hand, which improves the accuracy when shooting with both hands. If the grip area above the thumb-long recess and the indentation has a recess for a locking catch lever (claim 8), this contributes to better handling of the pistol, because the recess provided with respect to the raised thumb rest means the unintentional actuation of the locking catch lever and the associated locking of the closure.

In a further development, the lower edges of the two side surfaces have thumbnail-sized recesses (claim 9). These serve the simple removal of the magazine, especially in the event of malfunction of the weapon. If the magazine base also has corrugations on both sides that are accessible thanks to the thumbnail-sized recesses, magazine removal is additionally facilitated.

The handle itself preferably has the aforementioned ergonomic shapes and designs. In a modified embodiment, covers, or a shell or shells, made of a firm or elastic, rough material are attached to the handle in the grip area (claim 10), which contain the anatomical shapes and designs according to the invention.

The invention is described and explained below with the aid of illustrations. Show it:

1: A basic representation of a hand gun according to the invention with omission of details, in side view,

Fig.2: A side view of a slightly modified weapon with details, Fig.3: The view of Fig.2 with the hand of the shooter.

In Fig. 1, the handle with 1 and the chutes with 2 is designated. The handle 1 consists of the handle 3, the trigger area 4 adjoining it at the front with the trigger lever 5 and the trigger guard 6, and the front part 7. In the handle 3, a magazine 8 is inserted from below. The barrel chute 2 can be displaced in the longitudinal direction relative to the handle 1 on a guide track 9. The trigger area 4 with the trigger 5 and the trigger guard 6 determines a direction 10 which corresponds to the direction of the trigger finger of the shooter. This direction 10 includes with the guideway 9 an angle 11 of 5 to 15 degrees downwards.

2 further design features of the handle piece 1 can be seen. The whole handle 3 is roughened. Its rear side has a depression 22 in the upper area and a straight part 23 directed obliquely downward in the lower area, which projects beyond the depression 22 to the rear. Its visible as well as its invisible side have in the upper part a thumb-long and thumb-wide trough 24 adjoining the depression 22 with a lower embankment 25 and an upper embankment 26, which can be rounded and is therefore indicated by dashed lines. The underlying areas of the sides of the handle are raised in relation to the troughs 24. The front of the handle has a horizontally extending wall-like elevation 27, approximately a finger's width under the trigger guard 6.

A magazine holding button 30 runs across the handle and is accessible from both sides. It lies approximately at the level of the trigger 5 and the handle is raised there with respect to the trough 24. In the trigger area 4 above the trigger device 31, the grip piece has indentations 32 on both sides, the contour 33 of which can be rounded and is therefore shown in dashed lines. A safety button 34 above and slightly in front of the trigger lever 5 has wings 35 on both sides, which protrude through a window 36 in the trigger area 4 of the handle 1. A safety device containing a safety button 34 is the subject of the Austrian patent application A 2014/95. The trigger guard 6, which is oriented in the direction 10 (FIG. 1), has at the front a branch 37 rising to the front part 7, the outer surface 38 of which is roughened. A recess 40 with a contour 44 is provided above the trough 24 and / or the indentation 32 and partially receives a locking catch lever 41, the rest of which protrudes laterally. On the lower edges 42 of the sides of the handle 3, thumbnail-sized recesses 43 are provided, which expose the passage to a corrugated surface 46 of the magazine 8. At 45, a mounting option for an additional device is indicated.

Finally, FIG. 3 shows the same pistol as FIG. 2, but with the shooter's hand. The ergonomically particularly advantageous finger position can be recognized without providing the fingers with reference numerals in detail. The index finger points slightly downwards without tension, the middle finger is relatively close to the index finger. The thumb and the rest of the fingers are also comfortably and precisely positioned, without unnecessarily restricting the freedom of movement required for quick striking.
