Abstract
Description
- The present invention relates to double-action trigger mechanism for semi-automatic pistol.
- There are known semi-automatic pistols, with the trigger mechanism consisting of single-arm draw bar. The expression "single-arm" in connection with "single-arm draw bar" means draw bar consisting of only one bar placed along the single side of the magazine channel. Double arm then comprises two arms, each of them being placed along one side of the magazine channel.
- The trigger mechanism of pistols having single-arm draw bar operates in many cases in the single action mode (e.g. as it is with the CZ 75 ST or CZ 75 M pistols). Disadvantage of some double-action trigger mechanisms with single-arm draw bar is usually high trigger pull weight and inconsistent operation, resulting from passive resistance in the course of transfer of forces.
- This disadvantage was to a great extent abrogated by the introduction of double-action trigger mechanism utilized for example with the CZ 75 pistol and its clones, where the trigger mechanism is outfitted with symmetrical double-arm bar, which has no immediate contact with the hammer, but movement of the hammer is controlled by means of interposed connecting link, which facilitates transmission of force from draw bar to the hammer and partially eliminates incipient friction. This solution achieves that the trigger pull weight curve is not steep and there is overall reduction of the trigger pull weight making its operation more consistent and uniform. This design also attains higher comfort and accuracy of fire as with this solution there is almost no "trigger jerk" resulting from high and non-uniform trigger pull weight.
- Disadvantage, inherent in semi-automatic pistols with double-action trigger mechanisms having two-arm draw bar especially those with high capacity magazines, is necessity to use the frame with extended width and that particularly with large calibre semi-automatic pistols (e.g. 40 S&W etc.). The terms of production entail another disadvantage in complex and expensive manufacturing process of double-sided draw bars and other associated parts and components.
- Further, it is necessary to mention also existence of double-action trigger mechanisms comprising single-side bar which when the trigger blade is squeezed is driven forward in the direction of fire. Disadvantage of these versions is often already mentioned higher trigger pull weight and at the same time its relative complexity and comparatively expensive production of used parts and components.
-
US 5 000 075 A discloses a double action trigger mechanism of the semi-automatic pistol having the features of the preamble of claim 1 as defined in the appended claims. - The above mentioned shortcomings are eliminated to maximum by utilizing the double-action mechanism of a semi-automatic pistol, according to claim 1, the body of which comprises a frame with a magazine channel, slide, trigger pivotally mounted in the pistol body, a draw bar joined with the trigger for the transfer of the trigger motion when being pulled, the draw bar being located along one of the magazine channel sides and pivotally connected with the trigger for the movement of the draw bar in the direction towards the rear end of the pistol when the trigger is pulled, and a sear of the hammer for intercepting the hammer after its cocking automatically after discharge by the means of movement of slide towards the shooter or after its manual cocking for the first shot using hammer serrated surface, the principle of which consists in the fact that after cocking automatically the hammer after discharge by the means of movement of slide or after its manual cocking for the first shot, when pulling the trigger the draw bar presses the firing block lever which pivots around the pin, thereby unlocking firing pin and subsequently engaging the sear of the hammer for releasing the hammer and discharging the cartridge.
- According to one of advantageous embodiments of double action trigger mechanism the draw bar is arranged for engagement with the hammer lever during pull of the trigger in the course of the hammer cocking from its front position against the force of the main spring. In such a case it is advantageous when double action trigger mechanism includes roller, rotatable around fixed axis for rolling engagement with functional surface created on the draw bar at the final stage of the hammer cocking for the change of draw bar position in such a manner that it is released from its engagement with the lever and thus the hammer is tripped and under the force of the main spring strikes against the firing pin.
- Intended invention objective is to eliminate to the maximum aforesaid shortcomings being inherent in the existing double action trigger mechanisms, which objective is achieved by utilizing single-arm draw bar controlled by the trigger, which allows double action of the semi-automatic pistol and is guided by the roller and which is pushed for the reason of the trigger pull weight reduction in the direction towards the shooter, further by the new design of the ejector having more functions, by new design of the trigger pin fixation.
- In the production terms, the design of the trigger mechanism, according to the present invention is advantageous in that the parts and components used are, compared to parts and components of known semi-automatic pistols having double action trigger mechanism, simplified and restricted to parts of spindle character, stamped parts, or parts made by sintering under high temperatures and pressure into mould, without any requirements for further surface treatment.
- The present invention will be made more apparent using description of its advantageous embodiment with reference to herein attached schematic drawings, in which
Fig. 1 illustrates broken-out section of the semi-automatic pistol with the trigger mechanism in the condition when the hammer is being cocked from its front - initial position,Fig. 2 is a broken-out section of the semi-automatic pistol with the trigger mechanism in the condition of the final stage of release of the hammer being cocked from its front - initial position,Fig. 3 is a broken-out section of the semi-automatic pistol with the trigger mechanism in the condition, where the hammer is cocked and intercepted by the sear,Fig. 4 is a broken-out section of the semi-automatic pistol with the trigger mechanism in the condition of the final stage of the hammer release from its cocked position;Fig. 5 is a broken-out section of the semi-automatic handgun with the trigger mechanism in the condition after a cartridge discharge, andFig. 6 is an exploded view of the frame (in broken-out section) of the semi-automatic pistol, part of the slide and part of the trigger mechanism in disassembled condition. - As evidenced by the attached illustrations, pin 2 with pivotally mounted
hammer 3 thereon is embedded at the rear part of the frame 1 of the semi-automatic pistol with double action trigger mechanism according to the invention. At the body of thehammer 3 is sited the pin 4 with pivotally attachedlever 5 of thehammer 3 ended with the projection 6. This lever is at its upper part formed into abutting surface 7 which rests againstpin 8 sited in the frame 1. The projection 6 of thelever 5 of thehammer 3 comes into contact with the guide surface 9 formed in the frame 1. The pin 2 of thehammer 3 is secured in its position by thesurface 10 of thelever 5 which is in engagement with the slot 11 formed on the pin 2 crosswise to its longitudinal axis. - The front part of the frame 1 houses the
trigger 12 pivoted on thepin 13. Thetrigger 12 is by means ofpin 14 which is close-connected with thedraw bar 15 joined-up with thedraw bar 15 consisting of single-arm, which is placed at the one side of themagazine channel 16 and is loaded with thespring 17. On thedraw bar 15 is formed alug 18 designed for engagement with aboss 19 made at thelever 5 and with theprojection 25 made at thesear 26 of thehammer 3. Thelug 18 comes at certain moment also into engagement with thenose 21, which is made at thelever 20 of block offiring pin 39. Thedraw bar 15 is provided withinclined surface 22, which in the final stage of cocking motion comes into contact with the rotatingroller 23 which is axially mounted on thepin 8. Thedraw bar 15 is further provided with alug 24 which comes into engagement with thesurface 27 of theslide 28 when thesear 26 of thehammer 3 is about to intercept thehammer 3 in its cocked position. - At the rear part of the frame 1 on the
pin 8 is pivotally attached thesear 26 of thehammer 3 loaded by thespring 29, and further, on thepin 8 is pivotally attached thelever 20 of the firing pin block. Thepin 8 is secured in its position by theejector 30 which is with itssurface 31 in the engagement with thecrosswise slot 32 made up on thepin 8. Further at the rear part of the frame 1 is pivotally mounted thesafety 33 which is made ofstud 34 andsafety control 35 and is in its position secured by thecut 36 of theejector 30 which is loaded by thespring 37 and is in engagement withcrosswise slot 38 made up on thestud 34 of thesafety 33. - The
slide 28 also houses afiring pin 39, which is activated by thehammer 3 loaded with themain spring 40. - Further description concerns to the operation of trigger mechanism for the discharge from the front position of the hammer and discharge from the rear position of the hammer.
- When pulling the trigger 12 (see
Fig.1 ), thetrigger 12 moves around itspin 13 towards the shooter and the single-arm draw bar 15 connected with itspin 14 with thetrigger 12 shifts in the same direction. In the course of this movement thedraw bar 15 pushes with itslug 18 against theboss 19 of thehammer lever 5, which is connected by means of the pin 4 with thehammer 3, thereby actuating cocking of thehammer 3. In the course of this movement thelever 5 is closely guided by its projection 6, the angled lower section of which is moving along guiding surface 9 of the frame 1. Thelever 5 of thehammer 3 has at its upper section an abutting surface 7 (illustrated inFig. 6 ), which rests against the pin 8 (illustrated e.g. inFigs. 3 and6 ) seated in the frame 1. Thedraw bar 15 is pressed into engagement withlever 5 byspring 17 housed in the frame 1, acting against thedraw bar 15 from below. At the final stage of cocking motion illustrated in theFig. 2 , theinclined surface 22 made on thedraw bar 15 comes ontorotatable roller 23 which is rotatably mounted on thepin 8, whereas thedraw bar 15 is lowered as far as theboss 19 of thelever 5 is released from the engagement withlug 18 on thedraw bar 15. This trips thehammer 3, which under the force of themain spring 40 strikes thefiring pin 39 and thus discharges the cartridge in the barrel. Before the moment of disengagement between thelug 18 of thedraw bar 15 and theboss 19 of thelever 5 of thehammer 3, thedraw bar 15 with itslug 18 presses onto thenose 21 of thelever 20 of the block of thefiring pin 39, which pivots around thepin 8 and with itssurface 42lifts element 43 of the block of thefiring pin 39, which is positioned in theslide 28, thus unlocking thefiring pin 39. - During automatic function of the pistol, after discharge of a cartridge the
hammer 3 is automatically cocked when theslide 28 travels rearward towards the shooter, or thehammer 3 can be also cocked manually for the first shot using hammer head'sserrated surface 45 illustrated inFig. 6 . In this case, as shown inFig. 3 , thecocked hammer 3 is intercepted by thesear 26 loaded by thespring 29. In the course of cocking of thehammer 3 thedraw bar 15 is together with thetrigger 12 retracted partially to the rear towards shooter. This retraction of thedraw bar 15 and of thetrigger 12 in the rearward direction is provided by the projection 6 of thelever 5, which during cocking of thehammer 3 carries thedraw bar 15, which is joined by means of thepin 14 with thetrigger 12, on the jag 41 of thedraw bar 15. - As shown in
Fig. 4 , when pulling thetrigger 12, thelug 18 of thedraw bar 15 presses on thenose 21 of the firingpin block lever 20 which pivots around thepin 8. Thelever 20 with itssurface 42lifts element 43, thereby unlockingfiring pin 39, and subsequently thelever 20 with itscog 44 acts on theprojection 25 of thesear 26 of thehammer 3. Thesear 26 partially pivots around thepin 8 thereby releasing thehammer 3 whereby the cartridge is discharged. - After discharge, as per condition illustrated in
Fig. 5 , theslide 28 travels rearward towards the shooter and during this movement thehammer 3 is again automatically cocked. In order that thesear 26 could again intercept thehammer 3 in its cocked position, thesurface 27 of theslide 28 comes ontolug 24 formed on thedraw bar 15 and thedraw bar 15 is pressed down against the force of thespring 17. At the same time thelug 18 of thedraw bar 15 is disengaged from thenose 21 of thelever 20. Thelever 20 moves unhindered around thepin 8 and is not acting by itscog 44 on theprojection 25 of thesear 26 thereby liberating thesear 26 which under the force of thespring 29 again intercepts thehammer 3 in its cocked position. - After releasing the
trigger 12 in condition as shown inFig. 3 thedraw bar 15 loaded with thespring 17 is again lifted and is re-engaged withlever 20 of thefiring pin block 39 and the handgun is ready to discharge another shot.
