The invention relates to a loading aid device for a stick magazine which has a receiving space for cartridges and a magazine feeder which is acted upon by a magazine spring for pushing the uppermost of the cartridges located in the stick magazine against magazine lips of the stick magazine, comprising a holder part for inserting and fastening the stick magazine and a feed part held on the holder part for displaceable guidance of at least one cartridge to be loaded. The invention furthermore relates to a method for loading a stick magazine which has a receiving space for cartridges and a magazine feeder which is acted upon by a magazine spring for pushing the uppermost of the cartridges located in the receiving space against magazine lips of the stick magazine, by means of a loading aid device which has a holder part for inserting and fastening the stick magazine and a feed part held on the holder part for displaceable guidance of at least one cartridge to be loaded.
Stick magazines for receiving cartridges of firearms have a receiving space for the cartridges in which they are arranged in a stacked manner in one or two rows (the two rows offset in terms of height). The receiving space is delimited at the upper output end by magazine lips which taper the width of the receiving space and against which the uppermost of the cartridges located in the magazine bears, wherein a magazine feeder acted upon by a magazine spring acts on the lowermost of the cartridges located in the magazine or in the case of a two-row magazine on the lowermost cartridges of the two rows in order to push the uppermost cartridge located in the magazine against the magazine lips.
In order to load a stick magazine, the cartridges are normally introduced individually by hand into the stick magazine in that they, in a front region of the magazine before which the magazine lips end, are pushed in against the magazine feeder or the cartridges already located in the magazine and as a result are introduced into a front region of the receiving space of the magazine and are furthermore pushed into the rear region of the receiving space and below the magazine lips. This process requires a relatively large amount of force and is laborious.
Loading aid devices for stick magazines which have a holder part which can be placed onto an upper portion of the stick magazine and in which the stick magazine is held in a similar manner to the firearm have already become known. A feed part in the form of a rail with an undercut groove is fitted on the holder part, in which undercut groove the cartridges to be loaded have been threaded prior to placing onto the magazine. The cartridges arranged in a row in the feed part and lying on the upper side of the magazine are consequently pushed manually into the receiving space of the magazine with a handpiece which is displaceable along the rail-like receiving part and lies on the uppermost of the cartridges. The loading of the magazine can indeed be accelerated as a result of this, but the amount of force which has to be exerted to push the cartridges with the handpiece into the receiving space of the magazine is significant.
A loading aid device with a holder part which can be placed onto an upper portion of the stick magazine and on which an actuating part formed as a lever is pivotably mounted is furthermore known by prior use. By actuating the actuating part, an individual cartridge inserted into the loading aid device is pushed by a thrust piece past the magazine lips into a front region of the receiving space of the stick magazine and then pushed by a pusher into the rear region of the receiving space under the magazine lips. In the case of this loading aid device, the cartridges to be loaded must be inserted in each case individually into the loading aid device.
The object of the invention is to provide an advantageous loading aid device of the above-mentioned type which enables easy, quick and low-force loading of the stick magazine. This is achieved by a loading aid device with one or more of the features disclosed herein as well as by a method with one or more of the features disclosed herein.
The loading aid device according to the invention has a thrust piece which is adjustable between a passive position, in which it is located entirely outside the receiving space (9) of the stick magazine (2), and an active position, in which a tappet portion (14c) of the thrust piece (14) protrudes between the magazine lips (10) into the receiving space (9) of the stick magazine (2), wherein this adjustment of the thrust piece between the passive position and the active position of the thrust piece serves to push down the magazine feeder together with cartridges possibly already located in the receiving space of the stick magazine. As a result of this, a front free space is freed up in a front region of the receiving space of the stick magazine. The loading aid device according to the invention furthermore has a pusher which is adjustable between a feed position and a push-in position. The adjustment of the pusher from the feed position to the push-in position serves to push in one of the cartridges to be loaded which has been fed in the active position of the thrust piece and feed position of the pusher from the feed part into the front free space of the receiving space of the stick magazine, into a rear free space located in a rear region of the receiving space, which rear free space has been freed up by the thrust piece during pulling back of the thrust piece from the active position in the direction of the passive position. The cartridge is thus fully received in the receiving space of the stick magazine. The cartridge is thus located in a loading position.
The loading process is advantageously performed by the interaction of the movement of the thrust piece from the passive position into the active position and back into the passive position as well as the movement coupled thereto of the pusher from the push-in position into the feed position and back into the push-in position.
Several cartridges to be loaded can advantageously be received by the loading aid device according to the invention, wherein several cartridges to be loaded can be inserted into the feed part and are guided displaceably by it.
The adjustment of the pusher from the feed position into the push-in position is preferably performed by a tension spring which acts upon the pusher in the direction of the push-in position. A cartridge to be loaded can thus be pushed by the pusher through the action of the tension spring into the rear region of the receiving space and thus into its loading position.
For the purpose of adjustment of the thrust piece from the passive position into the active position and to adjust the pusher from the push-in position into the feed position, an actuating part is advantageously present which is mechanically coupled both to the thrust piece and to the pusher and which is adjustable from a starting position into an actuating position. The adjustment of the pusher from the push-in position into the feed position and the adjustment of the thrust piece from the passive position into the active position are thus brought about during the adjustment of the actuating part from the starting position into the actuating position.
The feed of the cartridge to be loaded into the front free space of the receiving space in the active position of the thrust piece and in the feed position of the pusher is advantageously performed by the action of gravitational force as soon as, in a front region of the receiving space which lies next to the tappet portion, the front free space with a sufficient size is freed up and the pusher has moved sufficiently far in the direction of the feed position. The front free space extends to below a front portion of the magazine lips below which the cartridge comes to lie in the region of its rear end.
The thrust piece is advantageously mounted in a linearly displaceable manner on the holder part, wherein it is preferably acted upon by a return spring into the passive position.
In one advantageous embodiment of the invention, the actuating part, which, for actuation, preferably has a grip portion, about which an actuating part pivot axis is mounted pivotably on the holder part. The actuating part is advantageously acted upon by spring force into the starting position, in particular by the return spring acting on the thrust piece and the coupling of the actuating part to the thrust piece.
The adjustment of the thrust piece is expediently performed in both directions in a forcibly coupled manner by the actuating part, i.e. in the case of a continuous adjustment of the actuating part from the starting position into the actuating position a continuous adjustment of the thrust piece from the passive position into the active position is performed and in the case of a continuous adjustment of the actuating part from the actuating position into the starting position a continuous resetting of the thrust piece from the active position into the passive position is performed.
The coupling between the actuating part and the pusher is expediently forcibly coupled only in one direction, i.e. a continuous adjustment of the pusher from the push-in position into the feed position is performed in the case of a continuous adjustment of the actuating part from the starting position into the actuating position, while the pusher can remain in the same position in the case of a continuous adjustment of the actuating part from the actuating position into the starting position at least over a portion of this adjustment of the actuating part. This is enabled in one advantageous embodiment of the invention in that the pusher has at least one guide pin and the actuating part has at least one guide surface, wherein the at least one guide pin of the pusher bears against the assigned guide surface of the actuating part only on one side. Instead, the actuating part could also have at least one guide pin which bears against the guide surface of the pusher only on one side. Other formations of such an at least partial release of the movement between the actuating part and the pusher are conceivable and possible, for example, by a guide pin which is arranged on one of the two parts and projects into a window recess on the other of these two parts, wherein the window recess has a larger clearance than the guide pin.
In one advantageous embodiment of the invention, the feed part has a rail with an undercut groove. Several cartridges to be loaded can be threaded into this undercut groove and be guided displaceably therein, wherein their feed to the front region of the receiving space in the active position of the thrust piece and push-in position of the pusher is performed by gravitational force.
If the terms “top” and “bottom” are used in the context of this document with reference to a stick magazine, this relates to an alignment in which the magazine lips of the stick magazine inserted into the loading aid device are located at the top.
If the terms “front” and “rear” are used in this publication, this relates to the firing direction of the cartridges.
Further advantages of the invention will be explained below on the basis of the enclosed drawing. In this drawing:
An exemplary embodiment of the invention is explained below on the basis of
The loading aid device has a holder part 1 which possesses a receiving opening 1a into which a stick magazine 2 with an upper portion can be pushed. The stick magazine 2 is fixed on the loading aid device after pushing into the receiving opening 1a of the holder part 1. The holding of the stick magazine 2 on the holder part 1 can be performed in an analogous manner to the conventional holding of the stick magazine 2 on a firearm. In particular, the holder part 1 can have for this purpose spring-actuated latching lugs 3a which engage in latching recesses 2a of the stick magazine 2. The latching lugs 3a can be arranged on preferably pivotably mounted latching elements 3. In order to open the holder and remove the stick magazine from the receiving opening of the holder part 1, the latching elements 3 can be pivoted counter to the force of the springs 4 which act upon the latching elements 3.
The latching elements 3 with the latching lugs 3a are, in the exemplary embodiment, arranged on an adapter element 5 which is held on a base part 1b of the holder part 1. By exchanging the adapter element 5, the holder part 1 can be adapted to different types of stick magazines, as various manufacturers use them. In order to exchange the adapter element, in the exemplary embodiment, a closure element 6 mounted displaceably on the base part of the holder part counter to the force of a spring 7 is displaced, whereupon the adapter element 5 can be removed from the base part of the holder part 1.
The base part 1b and the adapter part 5 jointly form a sleeve which has the receiving opening 1a.
The stick magazine 2 serves to receive cartridges 8, for example, 9 mm cartridges (=9×19 mm). The stick magazine 2 can be formed in a conventional manner in this case. It has a receiving space 9 for receiving the cartridges 8. The receiving space 9 is delimited at the top by magazine lips 10. These extend only over a rear part of the magazine, while there is a larger opening of the receiving space 9 at the top toward the outside in a front part of the magazine, which serves to load the magazine.
A magazine feeder 11 acted upon by a magazine spring 12 is arranged in the magazine, which magazine feeder 11 pushes the cartridges 8 arranged in the receiving space 9 upward, wherein the uppermost of these cartridges 8 bears against the magazine lips 10.
A feed part 13 is fixed on the holder part 1 of the loading aid device. This has a rail 13a with an undercut groove into which cartridges to be loaded are threaded. The cartridges 8 are thus guided displaceably from the feed part at a right angle to their longitudinal direction. The rail 13a is screwed on the holder part 1 in the execution part by means of flanges 13b.
The cartridges threaded into the undercut groove of the rail 13a are displaceable along the rail 13a.
A thrust piece 14 is mounted linearly displaceably on the holder part 1 parallel to a displacement direction 25 between a passive position (cf.
A pusher 16 is furthermore mounted pivotably on the holder part 1 between a push-in position (cf.
An actuating part 20 formed as a lever is mounted pivotably on the holder part 1 about an actuating part pivot axis 21 between a starting position (cf.
In the exemplary embodiment, the actuating part 20 is formed in two parts. The grip portion 20a is divided along its longitudinal center by the two parts screwed to one another. The two parts have in each case a guide extension 20b which possesses a guide surface 20c.
For pivotable mounting of the actuating part 20 on the holder part 1, the two parts of the actuating part 20 have, in the exemplary embodiment, in each case an axle journal 20d which engages in a bearing bush 22 arranged in the holder part 1. The bearing bushes 22 can also be dispensed with.
In each case a side plate 1c is fastened to the upper sides of the opposing wide-side walls of the base part 1b of the holder part 1. The pivotable mounting of the pusher 16 and of the actuating part 20 is performed on the side plates 1c. An intermediate space for the supply of cartridges 8 to the upper side of the stick magazine 2 is located between the side plates 1c.
By actuating the grip portion 20a of the actuating part 20, this can be pivoted between a starting position and an actuating position. The thrust piece 14 is in this case forcibly coupled to the actuating part 20 in both adjustment directions of the actuating part 20. In the exemplary embodiment, a coupling pin 23 which is attached to the actuating part and penetrates through a recess 14b in the thrust piece 14 serves this purpose. Since the actuating part 20 is pivotably mounted and the thrust piece 14 is mounted in a linearly displaceable manner, the recess 14b is formed as an elongate hole recess.
If the actuating part 20 is pivoted from the starting position into the actuating position, the thrust piece 14 is adjusted from the passive position into an active position by the forcible coupling to the actuating part 20. If the grip portion 20a is released by the user, the return spring 15 displaces the thrust piece 14 back into the passive position and in this case the actuating part 20 is pivoted back into the starting position as a result of the coupling to the actuating part 20.
The pusher 16 has guide pins 16a which protrude on opposing sides, are oriented parallel to the pusher pivot axis 18 and interact with the guide surfaces 20c of the actuating part 20. If the actuating part 20 is pivoted from the starting position into the actuating position, a pivoting of the pusher 16 from the push-in position into the feed position of the pusher 16 is thus performed through the interaction of the guide pins 16a with the guide surfaces 20c.
If the actuating part 20 is released by the user and pivoted back into the starting position through the action of the return spring 15, the guide pins 16a are held by the action of the tension spring 19 to bear against the guide surfaces 20c and the pusher 16 is adjusted back into the push-in position. This is, however, not essential. If the pusher 16 is fixed in the feed position, the actuating part 20 can nevertheless pivot back into the starting position with the lifting up of the guide pins 16a from the guide surfaces 20c. Such a lifting up of the guide pins 16a from the guide surfaces 20c over a portion of the resetting of the actuating part 20 from the actuating position into the starting position is performed during the loading process, as well be explained in greater detail below.
In order to explain the loading process, reference is made in particular to
If the actuating part 20 is actuated in that it is pivoted from the starting position into the actuating position, which is represented in
A pivoting of the pusher 16 about the pusher pivot axis 18 from the push-in position into the feed position is furthermore performed during the adjustment of the actuating part 20 from the starting position into the actuating position by the coupling to the pusher 16. This pivoting of the pusher 16 is performed in the exemplary embodiment by the bearing of the guide pins 16a of the pusher 16 against the guide surfaces 20c of the actuating part 20.
By pivoting the pusher 16 from the push-in position into the feed position, the bearing surface 16b of the pusher, on which the lowermost of the cartridges 8 arranged in the feed part 13, is moved toward the front end of the cartridge and consequently pivoted away from the cartridge. As soon as the bearing surface 16b of the pusher 16 has moved beyond the front end of the cartridge 8, it slips downward, wherein it slides out of the lower end of the guide of the feed part 13 and falls through the opening lying in front of the magazine lips 10 on the upper side of the stick magazine 2 into the front free space freed up through the action of the thrust piece 14 in the front region of the receiving space 8 of the stick magazine 2 and in this slips backward until it bears against a side surface of the tappet portion 14c of the thrust piece 14. The cartridge 8 then lies in the region of its rear end on the uppermost cartridge 9 already located in the receiving space 9 or, if such a cartridge is not present, on the magazine feeder 11. This rear end of the cartridge 8 lies below the magazine lips 10. In a front portion, the cartridge 8 can lie on the upper edge of the stick magazine 2. A resting on a part of the loading aid device would also be possible. This situation is represented in
The actuating part is furthermore reset from the actuating position back into the starting position. This can be performed by letting go of the actuating part 20 and the action of the return spring 15.
When resetting the actuating part from the actuating position into the starting position, the tappet portion 14c of the thrust piece 14 is increasingly raised up. Since the cartridge 8 about to be loaded lies with its rear side below the magazine lips 10, a driving up of the magazine feeder 11 with the possibly already fully loaded cartridges 8 is blocked. The cartridge about to be loaded is clamped with its rear end between the magazine lips 10 and the uppermost of the cartridges 8 already located in the receiving space 9 or, if no such cartridge is present, the magazine feeder 11. The pusher 16 pivots increasingly from the feed position in the direction of the push-in position until it bears against the tip of the cartridge. At the moment when the pusher 16 comes to bear against the tip of the cartridge 8, the cartridge 8 still bears with its rear side against the tappet portion 14c. As a result of this, it is blocked against a further displacement into the rear region of the receiving space 9. In the case of the further resetting of the actuating part 20, the pusher 16 thus remains fixed in this position, wherein the guide pins 16a raise up from the guide surfaces 20c. This situation is represented in
As soon as the actuating part is reset beyond this intermediate position in the direction of the starting position, the tappet portion 14c is pulled over the upper end of the rear side of the cartridge 8. A rear free space in the rear region of the receiving space 9 of the stick magazine 2 is thus freed up by the thrust piece 14. This rear free space lies below the magazine lips (10). The cartridge is now pushed into this rear free space through the action of the pusher 16 which presses on the tip of the cartridge 8. In the exemplary embodiment at least to the extent that the guide pins 16a once again bear against the guide surface 20c of the actuating part 20. In the event of a further resetting of the actuating part 20 in the direction of the starting position, an increasingly further pushing in of the cartridge 8 to be loaded into the rear region of the receiving space 9 is performed.
If the actuating part 20 has been reset into the starting position and the pusher 16 has reached the push-in position, the cartridge to be loaded is received entirely in the magazine and has thus reached its loading position, cf.
In the exemplary embodiment shown, a single-cartridge supply piece is represented as an optional accessory in
In one modified embodiment of the invention, instead of a feed part 13 with a rail 13a, a feed part could also be provided in an analogous manner to the single-cartridge feed piece 24, by which a single cartridge is displaceably guided and which could then be mounted fixedly on the holder part 1. The cartridges to be loaded would then have to be fed by the user in each case individually into the single-cartridge feed piece.
Various further modifications of the exemplary embodiment shown are conceivable and possible without departing from the scope of the invention as it is defined in the claims.
For example, the thrust piece 14 could thus be mounted in a different manner displaceably on the holder part 1. A pivotably mounted arrangement of a thrust piece would also be conceivable and possible.
Instead of a return spring which acts on the thrust piece 14 or in addition thereto, a return spring acting on the actuating part 20 could also be provided.
The cartridges 8 can be arranged in the receiving space 9 of the stick magazine 2 in one row or two rows (offset in terms of height).
Instead of a pivotably mounted pusher, a linearly displaceably mounted pusher could in principle also be provided.
Instead of a pivotably mounted actuating part, a linearly displaceably mounted actuating part could in principle also be provided.
In principle, it would also be conceivable and possible to provide separate actuating parts to actuate the thrust piece and to actuate the pusher.
A motorized adjustment of the thrust piece 14 and/or pusher 16 would also be conceivable and possible.
The tension spring 19 and the guide surfaces 20c of the actuating part 20 could also be designed so that the tension of the tension spring 19 is increased during pivoting of the pusher 16 from the push-in position in the direction of the feed position by the actuating part 20 directly from the push-in position. The return spring 15 could thus also be dispensed with and the tension spring 19 could also pivot the actuating part 20, if it is located in the active position and let loose, up to the passive position. This pivoting back would furthermore be assisted via a first part of the movement also by the force of the magazine spring 12 acting on the tappet portion 14c.
A modified exemplary embodiment of a loading aid device according to the invention is represented in
A first difference lies in the actuation of the thrust piece 14 by the actuating part 20. In this exemplary embodiment, the thrust piece 14 possesses a slotted link 50 into which the coupling pin 23 of the actuating part 20 engages. The advantage of such a slotted link guide lies in further improving the ability to adjust the motion sequence between the thrust piece 14 and the pusher 16. The thrust piece 14 can thus still remain substantially in the passive position, for example, over a first part of the motion of the actuating part 20 starting from the exchange position, while the pusher is already pivoted from the push-in position in the direction of the feed position.
In this modified exemplary embodiment, the spring 15 represented in the first exemplary embodiment can furthermore be dispensed with such that the resetting of the thrust piece 14 in the direction of its passive position is performed by the tension springs 19. For example, two tension springs 19 can be provided here, as represented. Return springs 51 are furthermore present for the actuating part 20, which could in principle also be dispensed with, such that the resetting of the actuating part 20 into the starting position could be performed only by the at least one tension spring 19.
For further improvement of the sequence, the form of the guide surface 20c is furthermore slightly modified in comparison with the first exemplary embodiment.
For the sequence of the loading process, reference is made to the description of the first exemplary embodiment.
