Definitions
- the present invention relates to firearms, and more particularly rifles with two superimposed smooth barrels.
- Firearms part of the variety of rifles come in a lot of different shapes and types for several decades. Different types of rifles have been developed for different types of shots. Through example, and without any limitation, there are rifles with smooth single-hinged barrels, two-barreled rifles rifles placed side by side, rifles with two smooth barrels superimposed, repeating single-barreled shotguns controlled, semi-automatic shotguns, as well than various other types of shotguns.
- the shotgun technology continues to evolve to respond to the different needs manifested by the followers of the shoot. A large number of factors are taken into account in the design of shotguns, such as appearance, weight, touch, ease of use, use final as well as the individual preferences expressed by the shooters.
- Rifles with two superimposed smooth barrels in particular are extremely popular with shooting enthusiasts. Rifles at two superimposed smooth barrels are particularly suitable for pigeon shooting.
- the present invention relates to improvements to rifles with two smooth barrels Bunk.
- the overall weight of a rifle with two superimposed smooth barrels represents a major problem for all models and all types of shotguns of this type. Lighter will the rifle with smooth barrel, easier will be its handling. When, during a shooting competition, priority is given to speed of handling and aiming, as is the case in pigeon shooting, the weight is particularly important.
- Rifles with two traditional superimposed smooth barrels specifically involve a joint of the type to solid spindle or pin.
- the hinge mechanism that allows the section making barrel / carcass office to swivel away from the portion of the firearm serving as a wafer, revolves around a specific defined pivot point of typically by a full spindle joint or by a trunnion.
- a solid pin type model requires a significant amount of material surrounding the spindle or trunnion and therefore a higher dimension in terms overall height of the rifle, which goes against the looking for a smoother, low profile rifle model.
- a major reason which militates for the need to have two load bearing surfaces relate to the surface area.
- a quantity of surface area additional is usually required to absorb the shock generated by the recoil of the firearm during the discharge of the latter. Consequently, given that the area of surface surrounding the joint portion itself cannot be increased, a second surface supporting the load must be intended to absorb a portion of the shock of the force of decline. Tolerances of load bearing surfaces must be taken into account in case one needs to two load support surfaces.
- a main object of this invention is to provide a two-barrel rifle apparatus superimposed which is light, easy to handle and which has a smooth appearance.
- Another object of the invention is to provide an apparatus for rifle with two superimposed barrels which has a low profile.
- Another object of the present invention is to provide a rifle apparatus with two superimposed barrels which has a new joint to articulate a portion of the device of rifle compared to another portion.
- Yet another object of the present invention is to provide a rifle apparatus with two superimposed barrels which includes a substantial abutment surface to absorb the shock associated with the recoil force resulting from the discharge of the rifle.
- Another object of the present invention is to provide a rifle apparatus with two superimposed barrels which presents a easy handling and control.
- Another object of the present invention is to provide a rifle apparatus with two superimposed barrels which includes a substantial abutment surface defined at least in part by a curved edge of the portion serving as a carcass and by a corresponding curved edge of the monobloc unit of the section acting as a cannon.
- Yet another object of the invention is to provide a rifle apparatus with two superimposed barrels which has a smoother and thinner appearance.
- Yet another object of the invention is to provide a rifle apparatus with two superimposed barrels which includes a stop surface between the portion of the rifle serving as carcass and the portion of the rifle serving as a barrel, the abutment surface defining a pivot axis spaced from the abutment surface, around which the portion is articulated acting as a barrel relative to the portion of the rifle acting as a carcass.
- Another object of the invention is to provide an apparatus for rifle with two superimposed barrels which encompasses an area of stop which also acts as a hinge surface, the abutment surface providing a substantial surface area to absorb the recoil shock of the rifle when discharging the gun.
- Another object of the invention is to provide an apparatus for rifle with two superimposed barrels according to the present invention which provides sufficient abutment surface to absorb the charge of recoil when discharging the rifle.
- the surface of stop also provides track articulation surface domed to eliminate the need for any spindle or trunnion joint.
- Yet another object of the present invention is to provide a rifle apparatus with two superimposed barrels which provides a unique articulation mechanism to articulate the portion acting as a cannon relative to the portion making carcass office, so that we eliminate the need to provide a notch on the bottom surface of the portion of the firearm serving as a carcass.
- Another object of the present invention is to provide a rifle apparatus with two superimposed barrels which uses a joint assembly which extracts the elastic force from rear-facing compression of an assembly of trigger, which reverses such force and redirect force towards the front portion of the gun in the purpose of operating the ignition pin.
- Another object of the invention is to provide an apparatus for rifle with two superimposed barrels which implies a pin ignition which is charged by moving a coil spring towards the front portion of the rifle.
- Another object of the invention is to provide security so that when you don't press trigger and when the striker tries to move towards the rear end of the gun, the striker is stuck by trigger and will not result in a discharge.
- Another object of the present invention is to provide a rifle apparatus with two superimposed barrels which retains a waterproof structure for an extended period of time life of the rifle.
- New Smooth-Shot Rifle Device Includes Surface of a curved track stop comprising a first surface of contact arranged on the section of the firearm corresponding to the carcass and a second setting surface contact arranged on the monoblock unit of the weapon section fire corresponding to the cannon.
- the contacting surfaces are curved in the form of a curved track so that they reciprocally come into sliding contact during of the articulation of the section corresponding to the barrel by relation to the section of the smooth-barreled shotgun apparatus corresponding to the carcass.
- the contacting surfaces provide sufficient surface area for absorb the shock of the recoil force when discharging the gun.
- the contacting surfaces are defined, from uniquely, by a female or concave portion formed on the one-piece unit of the barrel shotgun portion smooth corresponding to the barrel and by a male portion or convex formed on the portion of the barrel shotgun apparatus smooth corresponding to the carcass.
- the structure of this type articulation provides an overall profile of the device of small-bore smooth-barreled shotgun since the pivot axis defined by the contacting surfaces are spaced from the contacting surfaces. Any specific joint and no journal is required at the specific pivot axis, unlike what is the most traditional shotguns, if although we can reduce the height dimension of the rifle to smooth barrel.
- the unique curved track stop surface also makes sort of pull the barrel away from the carcass when we opens the cylinder head, eliminating the need to provide a cut in the portion corresponding to the carcass, which is generally required in most types of model rifle with two smooth superimposed barrels.
- Another aspect of the present invention involves a unique reverse direction trigger assembly.
- the spring main helical trigger is cocked by compressing the spring toward the end of the gun corresponding to the mouth.
- the spring of the trigger relaxes and exerts an oriented force backward on the hinge assembly which at its turn, redirect the force towards an ignition pin in the direction oriented towards the anterior portion or towards the end of the rifle with a smooth barrel corresponding to the muzzle.
- the present invention relates a shotgun apparatus 30 generally comprising a section 32 corresponding to the barrel arranged at the end front or distal of the gun and a section 34 corresponding to the carcass / plate, arranged at the end rear or proximal of the shotgun apparatus.
- the section 32 corresponding to the barrel includes a monobloc unit 60 to which are fixed an upper barrel 62 and a barrel lower 64.
- a pair of ejection systems 56, 58 is also housed in section 32 corresponding to the barrel.
- the carcass section 34 contains the trigger assembly 38, the locking system 100, the internal connections for armament, security assembly 120 as well as various other operating parts of the barrel rifle apparatus smooth 30.
- the plate of the smooth-barreled shotgun is attached to the rear portion of the carcass.
- the smooth-barreled gun apparatus 30 includes, in one embodiment, a shotgun two smooth guns superimposed.
- An assembly of cannons 32 includes a first barrel or upper barrel 62 (see the Figure 3) arranged in alignment with a second barrel or lower barrel 64, while being mounted directly on this latest.
- the rifle with two superimposed smooth barrels 30 includes further an end 36 occupied by the butt, which can include a recoil pad, and one end 37 occupied by the mouth.
- the firearm 30 further comprises an assembly of trigger 38 for discharging the gun and a system of lock 40 actuated by lever to open the cylinder head the shotgun apparatus.
- the corresponding portion 32 at the barrel ends at the end of the smooth-barreled rifle, occupied by the mouth.
- an assembly is shown articulation 42 which is defined in part by a portion male articulation 46 (see FIG. 7) formed on the section 34 corresponding to the carcass and by a portion female articulation 48 (see FIG. 8) formed on the monobloc unit 60 of section 32 corresponding to the barrel of the notably smooth rifle apparatus.
- a curved stop zone is defined 44 (i.e. a curved track). Stop zone 44 further includes a convex abutment surface 45 which provides a main bearing surface for contacting by sliding with corresponding concave abutment surface 47 (see Figure 8) formed inside the portion female articulation 48 on the monobloc unit 60.
- the invention comprises a pair of stop zones 44 and abutment surfaces 45, 47 formed on either side of the weapon fire 30.
- the abutment zones 44 and the abutment surfaces 45, 47 act as both a hinge and a bearing surface for the articulation of section 32 corresponding to the barrel relative to section 34 occupied by the carcass / plate and to absorb the recoil force of the firearm when dump.
- the articulation assembly 42 defines an axis of pivot 50 (see Figure 3) which is distant or spaced from stop zones 44. An articulation proper does not exist not to the pivot axis 50.
- the first abutment surface curve 45 and the second stop surface curve 47 (see figure 8) lean against each other to form the joint.
- the first and second abutment surfaces 45, 47 come into reciprocal contact by sliding along the curved track in a variable overlap relationship (in depending on the degree of articulation of the portion 32 corresponding to the barrel relative to the portion 34 corresponding to the carcass / plate).
- the main benefit of the present invention relates to the amount of surface area provided by abutment surfaces 45 and 47 of the curved track 44.
- abutment surfaces 45 and 47 When the breech of the smooth-barreled shotgun apparatus is closed, the surface areas of abutment surfaces 45 and 47 come into reciprocal contact along essentially the entire the curved track 44 (see FIG. 7). We thus obtain a substantial surface area which is sufficient, nothing more, to adequately absorb the recoil force when discharge from the smooth alkanol rifle.
- most of the other traditional two shotguns stacked guns require two separate stop surfaces to provide sufficient abutment surface area for absorb the shock associated with the recoil force of the shotgun smooth during discharge.
- the abutment surface 45 of the curved track 44 has approximately 1/8 "wide and one length approx. 2-5 / 16 ''. However, it will be understood that these dimensions can vary without departing from the frame and the spirit of the present invention. As shown in Figures 7 and 8, the convex portion 46 and the concave portion 48 come into contact with each other along their lengths and their respective widths and, over the substantial portion of their length, along the abutment surfaces 45 and 47. In Consequently, the total surface area of the curved runway 44 is important in relation to the surface area of a fixed joint or a traditional journal provided on a rifle device with two superimposed barrels.
- the abutment area or the curved track 44 is able to absorb all of the recoil force generated during the discharge of the firearm.
- two separate stop surfaces are unnecessary, there is no no need to coordinate tolerances against different and separate contact surfaces in space.
- the tolerances of two or more stop surfaces must be precisely adjusted so that a stop surface does not support a higher load than that supported by the other surface stop.
- the moving parts and the mechanism Smooth-bore shotgun lever will come loose.
- the current invention requires no coordination of tolerances critical of this type given the abutment surface unique substantial provided by each curved track 44.
- the curved track or the area of stop 44 provides hinge or bearing surfaces against which the two portions of the shotgun come from arrange for articulation purposes. Contrary to rifles with two superimposed barrels of the prior art, when a pivot pin, socket or pin specific to the precise pivot point, the point pivot 50 (see Figure 31) defined by the track convex or by the stop area 44 is spaced from the surfaces of articulation proper (i.e. the surfaces of stop 45, 47). As a result, the actual positioning of the point pivot point 50 must not be located in a the shotgun apparatus corresponding to a quantity substantial structure. In fact, the pivot point defined 50 can correspond to a place where no structure does not exist (i.e.
- assemblies are shown ejection 56, 58 operatively mounted on the unit monobloc 60 of section 32 of the present invention corresponding to the barrel.
- the unit monobloc 60 provides the first part of cannons 62, 64 and acts as an interface with section 34 corresponding to the carcass / wafer.
- the purpose of the monoblock unit 60 is further rigidly connect the upper barrel 62 and the barrel lower 64 of the 30 barrel two-barrel machine Bunk.
- the ejection assemblies 56, 58 trigger the movement of the ejection heads 66, 68 (which come into contact with the side bottom of the flanged portion of the pellet cartridge) towards the exterior with respect to the base end 70 (see the Figure 6) of the monobloc unit 60.
- Ejection heads 66, 68 are intended to be pushed outwards with a sufficient force to unload the unit in its all one pellet cartridge consumed.
- Figures 9 to 14 the details of the ejection assembly in the absence of the carcass or guns.
- Figures 9 to 11 show the components ejection system 56 after firing with the gun.
- the elements are represented ejection of the ejection system 56 before having fired with the gun.
- the system ejection 58 is identical in terms of operation and structure to the ejection system 56. Consequently, one will only address the ejection system 56.
- the ejection system 56 includes an ejection spring 76 which gives outward prestressing to other ejection elements.
- a guide 72 of the ejection spring holds the spring in place.
- the combination of spring 76 and of the spring guide 72 is inserted into openings of appropriate dimensions practiced in the barrels and is held in place by suitable stops trained to inside the barrel assembly.
- An ejection striker 77 is coupled to the ejection assembly.
- a cam link 79 is part of the ejection assembly and is guided by the carcass of the firearm. The striker 77 hammer office and strikes the head of the cam joint 79 when the cartridges are ejected.
- the cam joint 79 further includes a shoulder 80 which bears against the unit monobloc 60 in order to limit the movement of the ejection assembly 56.
- the ejection head 66 is fixed to the cam joint 79 and is used to force the cartridge out of the chamber.
- a ejection head pin 67 holds the ejection head 66 at the state coupled to the cam joint 79.
- An ejector trigger 82 is used to retain the spring and the striker after firing.
- An articulation of ejection trigger 82 is used for decoupling the ejection trigger after opening the rifle.
- a screw of sync setting 86 is used to set the synchronization of the ejection between the two guns.
- a cocking lever 90 rotate forward (see Figure 9) and between in contact with the ejector trigger 82, causing that the trigger 82 turns clockwise shows so that it can come into contact with the notch 83 of the ejector striker 77.
- the ejection trigger 82 comes into contact with notch 83 on the striker 77 for the purpose of holding the striker ejector 77 in position.
- the cam portion 88 of the cam joint 79 is guided by the tracks in the carcass.
- the spring 76 When the ejector striker 77 is gripped by the ejector trigger 82, the spring 76 is not able to exercise a subsequent prestress on the ejector to the outside. However, the tracks in the carcass force said spring to move outward for an approximate distance of 3 mm. This displacement is used to eject the cartridge consumed.
- the end of the two cannons move away from the carcass to leave a passage free to eject the consumed cartridge, the end of the ejector trigger joint 84 comes into contact with the quick-release cocking lever 90. This setting contact forces the ejector trigger 82 to move away from the striker 77.
- each cannon takes place simultaneously.
- the adjustment screw 86 rests on 84 ejector trigger joint and affects the moment decoupling of said articulation.
- the locking system 100 is shown in the figures 15-22.
- the locking system 100 is shown in the unlocked position in Figures 15 to 18 and it is shown in the locked position in Figures 19 to 22.
- the upper lever 104 is also used as an arm crank or as a lever for moving the bolts lock 106 to insert them into the slots or grooves 120 in the monobloc unit 60 or in order to remove.
- the disconnector 108 of the rocker interfaces with the upper lever 104.
- the disconnection device 108 of the rocker is pushed back or is returned by cam back by the upper lever 104 in the rocker 140 (see Figures 23-31).
- pins 135 have the possibility of withdrawing by deviating bait or primers consumed after the shot (s). Of this way, we also block the ignition pins when the trigger fails while the rifle is in an unlocked position.
- a spring (not shown) pushes the disconnection device 108 from the rocker back to its locked position.
- a device 110 for disconnecting the trigger joint is coupled by screw thread to a transverse element 112 (see Figure 22) which extends between locking bolts 106.
- the device for disconnecting the articulation of trigger 110 includes a rear end surface 111 which contacts the trigger joint to squeeze rear trigger joint.
- a locking cam 114 is fixed to the upper lever 104 via a fixing device (not shown) such as a screw or a brooch, as will be understood by those skilled in the art specialized in technique.
- a cylindrical body 116 extending down from lever 104 is coupled to the locking cam 114.
- a groove 118 is formed in the cylinder 116, in which one end of the device for disconnecting the rocker 108.
- Locking bolts 106 are inserted into slots 120 formed in the monobloc unit 60. Bolts of lock 106 prevents the lever mechanism from opening after closing the breech of the firearm. Bolts locking 106 include an external surface 107 angular or conical which facilitates the contacting of locking bolts 106 with slots 120 sized suitably in the one-piece unit. When the point contacting edge 107 is subject to wear, the locking bolts 106 are loaded by a spring for maintain a tight fit.
- the cross member 112 maintains together the locking bolts 106 and forces these to move in the form of a unit.
- the bolts of locking 106 and the transverse element 112 can be machined or otherwise made to obtain unit.
- the combination of locking bolts 106 and the cross member 112 can be manufactured by assembly of separate parts. A pair of screws 113 (only one being shown) holds the bolts together lock 106 and the transverse element 112.
- Monoblock 60 is designed to provide an interface with the carcass (i.e. carcass 34 as indicated in Figure 3) and with the locking system 100, on the one hand and with the barrel tubes 62, 64 (see Figure 3), on the other go.
- FIGS. 23 to 31 the firing system 130 is shown.
- the firing system 130 is shown before pressing the trigger.
- Figures 26 to 28 we represents the firing system 130 once you have pressed on the trigger, but just before the rocker starts movement.
- Figures 29 to 31 show the system firing 130 after pressing the trigger.
- the firing system 130 generally comprises an arming lever 90, a link joint 132, a spindle assembly 134, a trigger joint 136, a striker 138, a rocker 140, a trigger 142, an articulation of trigger 144 and a mass of inertia 146.
- the assembly, operation and construction of these subparts of the 130 firing system are discussed below.
- the cocking lever 90 is used to cock the firearm once a shot has been taken. A pocket is cut in the carcass so that the cocking lever 90 is housed there.
- the cocking lever rotates around pivot point 145, causing the front portion of the cocking lever 90 to drop (giving rise to the rearward movement of the striker 138).
- the front of the cocking lever 90 is pushed up through the barrel, causing it to rotation around the curved portion. During this rotation, the cocking lever 90 pulls the striker 138 in the direction of the front of the gun.
- trigger joint 136 falls into a trigger position over the striker 138.
- the springs in the preloaded state of the spindle 135 press the end of the ignition pin 135 so that the latter comes into contact with the portion upper of the rocker 140 in a position which grasps the trigger joint and holds it in place until next shot.
- connection joint 132 couples the cocking lever 90 to striker 138.
- the articulation 132 is fixed to the lever arm at pivot point 147.
- a spring 139 (not shown in Figures 23 to 31) presses striker 138 towards the rear of the rifle.
- the trigger joint 136 is hooked from above striker 138 and holds it in position until what we pull the trigger 140.
- the articulation of connection 132 moves approximately in a straight line (even if the connection of the connection joint 132 to the cocking lever 90 gives rise to a slight vertical movement cocking lever, such movement is not enough to trigger any type of problem).
- Ignition pin assembly 134 includes a pin 135 and the spring 137 of the ignition pin.
- the ignition pin spring puts rocker 40 in a state of preload in a firing position. This movement allows to cock the rifle.
- Each ignition pin 135 limits the movement of all the elements associated with this pin, including including rocker 140 and striker 138. The movement of the ignition pin 135 is limited by a pin (not shown) which fits into a notch 141. The extreme end of the ignition pin 135 (not shown) is narrowed and comes into contact with the primer the cartridge being fired, as will be understood skilled in the art.
- the trigger joint 136 is used to reduce the charge transfer to the trigger surfaces.
- the striker 138 when in position fully armed, develops horizontal load substantial.
- the area between the joint of trigger 136 and striker 138 forms an angle so that the intense horizontal force coming from the striker generates a small vertical force which applies a rotational force upward on the trigger joint to release the striker 138.
- the rocker 140 limits the upward rotation of the trigger joint 136.
- the striker 138 is held against connection joint 132 by a nut striker 143.
- the trigger turns the rocker 140 which in turn releases the trigger joint 136.
- the reduction of forces caused by the trigger joint 136 provides a lighter and more uniform movement of the trigger.
- the striker spring 139 is shown in Figures 2 to 6, but it is not shown in the Figures 23 to 31
- the rocker 140 After reversing the energy or the impulse, hits the ignition pin 135 and moves the pin 135 in the direction of the particular primer (not shown).
- the rocker 140 has two main duties. First, it transfers energy of striker 138, oriented rearwards at the energy of the ignition pin 135, facing forward. Secondly place, it acts as a trigger which allows relaxation to release the system.
- the trigger joint 144 allows the trigger to rotate 142 and transfers the rotation of the trigger to the rocker 140.
- a front portion of the trigger 142 is used to grab rocker 138 when trigger triggers failure so that you don't press the relaxation.
- a first frontal contacting surface 152 comes into contact with one of the rockers on a surface 154 contact with the trigger (see Figure 29) function of knowing the rocker 140 which has been set in a prestressed state towards safety (as we described below).
- the rocker which was not affected by the trigger is pushed out of the way via its associated rocker 138. In this way, the trigger joint can move forward and put in contact the second rocker with one of the second lateral contacting surfaces 156.
- the flywheel 146 is used as a counterweight. At during the recoil of the rifle, the mass of inertia pulls the trigger articulation towards the rear of the rifle (in overcoming the prestressing force exerted by the spring 150) to disconnect it from the rocker. The mass of inertia 146 is free to move vertically thanks to its positioning in a U-shaped saddle 158. The mass of inertia 146 prevents the trigger from rotating around its point of pivoting when the rifle is for example lowered.
- a hinge spring of the trigger 150 puts the hinge detent 144 in prestressed condition in one position facing forward. The spring also returns the trigger 142 in the position corresponding to an absence of fire.
- a 170 barrel (partly shown in section) is attached to section 32 corresponding to the guns and interfaces with section 34 occupied by the carcass (also partially shown in section).
- Barrel 170 includes a pair of opposite lugs 172 which are inserted into corresponding slots 174 (shown in dotted lines in Figure 32), so that the opposite studs 172 (a only shown in Figure 32) have locations that they can occupy in order to place the 170 barrel in a appropriate position.
- a latch 176 put in a spring preload state pivots around the pivot point 178 to spread and contact a hook 180 with respect to a corresponding female area on a fixing block 182 extending downwards (which is represents a dotted line in Figure 32).
- the barrel 170 and the carcass 34 come into reciprocal contact along a first vertical surface 184 and along a surface of lower curved guide or stop 186. It should note that these surfaces, in combination with the bearing surface 145 (which comes into contact with an arcuate surface formed in the monoblock unit) are all arranged on one side of a defined pivot point of barrel assembly 32 relative to the carcass section 34.
- the carcass defines surfaces 145 and the corresponding abutment surface relative to to the stop area 186.
- the surfaces on the barrel, which come abut carcass 34 to provide abutment areas 184, 186 act in combination with the bearing surface 47 (see figure 8) formed in the monobloc unit to petrol “tighten together” the surfaces on the carcass 34 which are part of the stop zones 184, 186, and the surface 145. This gives a tight fit for the joint created by the surfaces 186 (comprising at the times the appropriate portion of the 170 barrel and the appropriate portion carcass 34) and the curved track 145 formed in the carcass 34.
- a setting life 190 is provided in the barrel 170.
- the adjusting screw 197 can be used to vary the pressure exerted by the drum 170 on the carcass 34 in the abutment zones 184, 186.
- the slot 174 is elongated to allow some adjustability relative to to the abutment surfaces 184, 186.
- Yet another aspect of the articulation or mechanism lever concerns the surfaces which lean against each other the others in the stop zone 192 (as shown in dotted in Figure 32) when the lever mechanism closed.
- a surface of the monobloc unit 60 comes to rest against a surface on the carcass 34 in the abutment zone 192.
- a first system concerns a security system 200 incorporated in the articulation of detent 144.
- An extended flange 202 blocks the path of the striker 138 when does not press the trigger 142.
- the flange extended 202 will block striker 138 (any of two or both) and prevent it from coming into contact with the rocker 140.
- a second security system is represented in the Figures 33 to 38.
- a switch is used 204.
- the 204 safety sensor adjusts the gun firing sequence.
- Safety switch 204 can be positioned so that any of the cannons fire first before the other.
- the safety switch 204 can be either left or right and can be submitted to forward or backward movement. Movement left-right will determine which of the two barrels of the weapon to fire (the upper barrel or the lower barrel) that goes unload the trigger. Placing the power switch so that the "O" is exposed is going to cause that one obtains a discharge in the first place from the upper barrel ("Over" in English).
- the security system 200 more particularly includes a safety switch 204 having a ribbed area raised 208, a suspended median safety slide 210, and a pivoting selection arm 212.
- the slide of median safety 210 encompasses opposite areas 214 in the form of notches which are resized to accommodate extension sections, similar configuration, flanges 218 extending downwards from upper switch plate 204.
- One pin 220 connects the flanges 218 to each other.
- the upper switch plate 204 is mounted on the outside of the gun carcass in inserting flanges 218 through holes (not shown) formed in the upper section of the carcass 34.
- the median safety slide 210 is then fixed by sliding over the extension sections 216 so that the middle safety slide 210 is suspended via extension zones 216.
- a second pin 222 is inserted through the carcass and through a corresponding hole 224 in the safety slider 210 and through which the orifice 226 of the selection arm 212, respectively for the purpose of fixing the assembly in square.
- a slot 228 formed in the selection arm 212 overlaps an elastic pin 220. In this way, we keeps the selection arm 212 in the same orientation front-rear than that of the upper safety plate 204.
- An indexing ball 230 is inserted into a notch 232 in the side lower of the intermediate support structure 210.
- the ball 230 is supported by a helical spring 234 (see figure 35) which puts the ball in a prestressed state contact with zone 232 in the form of a notch.
- Ball 230 indexes the swivel selection arm 212 by in relation to one of the two positions below: a position of Safety "commissioning" corresponding to a movement toward the back of switch 204 and a "put" position in service ”of security corresponding to the movement towards the front of switch 204.
- the selection arm 212 also includes a shaft of selection 236, a socket 238, and a head 240 in the form of cone.
- a circular recess 240 of annular shape is defined by the cone-shaped end 240 and by the socket 238.
- Safety switch 250 includes a safety button 252 which, similarly to the embodiment anterior, includes a raised area with ribs.
- a safety plate 254 (in relation to which extends button 252) includes a portion in one piece of lower extension 256 which forms a slit longitudinal 258 into which are inserted stationary uprights 260, 262 coupled to the carcass 34.
- a selection arm 264 which determines that of the two barrels (the upper barrel or the lower barrel) is aimed at in the first place, similarly to the previous embodiment.
- a new surface with four faces extends from in solidarity with the selection tree 264.
- the ball 270 is indexed in an upward direction in contact with one of the four faces (the faces form an angle and converge at their lower edge 271, 273 as shown in FIG. 40).
- the ball has the possibility of coming into contact with a pair first slots or deep grooves 272 (only one being shown in Figure 40) or alternatively in contact with a pair of second shallow slots or grooves 274 (only one being shown in Figures 40).
- the button 252 can move to take a position either left or right, and the ball will be switched between a brought into contact with one of the inclined surfaces which define the grooves 272.
- a fixing device 276 is inserted through the carcass portion of the gun to keep safety assembly 250 in place. The device 276 can be inserted by screw thread into the carcass.
