    TECHNICAL AREA
    The present invention relates to a loading tray for a single loader small bore rifle, wherein the loading tray is slidably mounted on a holder, wherein the closure is movable in a closure guide from a retracted position to an advanced locking position and with its bottom loading tray from the bottom pivoted the feed path of the closure.
    STATE OF THE ART
    From the prior art of the applicant, in particular the prospectus of the company Bleiker «Metallic sports guns» is a loading trough for a single loader small bore rifle known in which the loading trough is slidably mounted on a bracket. In this case, a number of return springs are provided under the trough and the loading trough is aligned with a run-up track in the direction of the closure. When the closure in a closure guide is moved from a retracted home position to an advanced locking position, the bottom surface of the front of the closure forces the loading cavity with its run-up against the force of the springs downward out of the travel of the closure.
    The old loading trough floats, so to speak, exclusively on four springs and is guided only by lateral noses, which at the same time also prevent the loading trough pops up. These guides are kept very wide, otherwise there would be a jamming of the loading trough. As a result, the charging well has many degrees of freedom. When advancing the shutter it tilts first from the back, then only in front.
    This loading tray allows insertion of a single cartridge in a simple manner in the area in which then manually advances the cartridge in the bullet bearing by hand. However, the cartridge can not come to rest in the actual loading trough when inserting into the charging trough or it can tilt when manually inserting the cartridge into the warehouse, or because the charging trough dips at high pressure from top to bottom.
    PRESENTATION OF THE INVENTION
    Based on this prior art, the present invention seeks to provide an improved loading trough, in which such tilting can be safely avoided.
    This object is achieved according to the invention in that the loading trough is articulated to the holder along a longitudinal axis to the rifle, that an about a transversely to the longitudinal axis of the rifle axis provided pivotable control element is provided, which a first and a second free End has that the first free end in its rest position of the control in the distance traveled by the closure path from the retracted position to the advanced locking position projects that the second free end in the rest position from below against the loading trough pushes that one for a return movement to the pivot axis of the control is provided in the rest position executed return spring, and that upon movement of the closure from the retracted position to the advanced locking position, a front part of the closure abuts against the first free end and the control pivoted to the rest position, the second free end releases the loading tray.
    The loading tray is designed so that the insertion of a small caliber cartridge in the bullet bearing is easy and possible in all shooting positions. Due to the inventive design, the cartridge is inserted absolutely centrally and without damage in the chamber. A tilting of the cartridge is excluded and safe charging is ensured even by inexperienced shooters.
    In this case, the loading tray may have a beveled bottom, against which in the rest position a rounded end of the second free end pushes and securely locked.
    The loading tray according to the invention may also have a high side wall to drive the cartridge optimally.
    In such a loading tray according to the prior art as well as in the present loading tray, the small caliber cartridge must always be pushed by hand into the chamber. This happens at least until the lead bullet is completely in the cartridge chamber. An advantage of the new loading trough is that this manual insertion process compared to the prior art is greatly facilitated because the loading trough can not dodge down as a whole and that advantageously the cartridge can not escape through a side high wall.
    In addition, the new loading trough in the front area contains a spring-loaded nose, which compensates for the difference in diameter from the bullet and cartridge edge.
    Another advantage of the new charging trough is that the jerking of the shutter during advancement no longer occurs, since it is on the one hand in the loading trough itself and the control to well-defined movements. Furthermore, the spring force to return the control can be significantly lower than the Fe derkraft of the four springs in the version according to the prior art, since the loading tray is positively locked in the open state by the control. In the prior art version, the springs had to be so strong that the loading tray was not pressed down during manual loading, which was achievable only with a compromise solution. All in all, the closure can be significantly easier to move forward in the embodiments of the invention, which is an advantage.
    The control may have a C-shape, wherein the central part is articulated to the transverse axis. This pivot axis of the control is located below the closure in front of the front edge of the closure when the closure is positioned in its rearmost position. This results in a positive lever ratio. In another embodiment, not shown in the drawings, this pivot axis of the control is not located in front of the front edge of the closure. It can also be a little further back.
    The front of the first free end is advantageously concavely curved, so when a pivoting of the control with this front, the control) engages in a front of the loading tray and actively presses down.
    The closure is in the rearmost position, the loading tray is supported by the sprung control so that the loading tray is locked and can not move down when loading the cartridge.
    The loading trough itself is not sprung and is kept hinged exclusively by the holder. With little friction between the bracket and the charging trough, the loading trough can simply fold down laterally due to its own weight when the control element releases the charging trough when the shutter is pushed forward.
    Further embodiments are given in the dependent claims.

    DESCRIPTION OF PREFERRED EMBODIMENTS
    Fig. 1 shows a perspective view of a gun part with housing, closure and loading trough according to an embodiment of the invention. The housing 3 is connected to a base plate 7 on which the shutter guide 2 is mounted. Between the housing 3 and the shutter guide 2 is a clearance, which is sufficiently long to put a cartridge on the loading tray 4, which bounds the shutter guide path.
    Fig. 2 shows another perspective view of the gun part of FIG. 1. The closure 1 is in its rearmost position and gives a good view of the loading trough 4 free. This is articulated laterally in the longitudinal direction of the holder 5. By the reference numeral 15, the longitudinal pivot axis of the loading trough 4 is indicated on the holder 5. The loading tray 4 is arranged in Fig. 2 in its uppermost position. It has on the opposite side of the holder 5, a high side wall 24, which simplifies the insertion of a cartridge before advancing.
    Fig. 3 shows a detail of the perspective view of Fig. 1 or Fig. 2 from the bottom side, with only parts of the holder 5 and the shutter guide 2 and the zurückbewegte shutter 1 are shown. Further, the C-shaped lever 6 is shown, which is arranged around a shaft 10, which is a transverse pivot axis 20. The shaft 10 is connected to the base plate 7 or other housing parts, for example, so that it remains in place during a movement of the closure 1.
    The C-shaped double lever of the control 6 has two opposite free ends. The one free end is the closure near free end 11 and the other end is the loading well near free end 12. The loading well near free end 12 is oriented between oblique to nearly perpendicular to the longitudinal direction of the gun barrel and has an upper rounded end 13 which is shown FIG. 3 abuts against a chamfered lower surface 14 of the loading trough 4. The loading well-near free end 12 of the control element 6 is preferably at right angles to the inclined bottom surface 14. The free end 12 is arranged so that by the chamfered lower surface 14 of the loading tray 4 is self-locking and thus the loading tray 4 no longer press down leaves. The loading well-near free end 12 stands almost perpendicular to the chamfered lower surface 14 of the loading trough 4th
    Thus, the loading tray 4 is on the free end 12 and can not pivot down if a user of the rifle pushes the cartridge too much. The other free end 11 of the lever 6, which ends spatially in front of this in the lower region of the closure 1, is itself pivoted downwards when the closure 1 is pushed forward so that the other end 12 of the lever folds downwards and the loading trough 4 can lower by their own weight around the longitudinal pivot axis 15. On the axis 20, a return spring 9 is mounted, with the C-shaped control element 6 is reset by a pivoted by advancing the shutter 1 position in the position of FIG. The underside 16 of the loading tray 4 optionally takes on the upper side of the C-shaped control element 6.
    3, a spring tongue 21 can be seen from below in the middle of the loading trough 4, which is separated by two lateral slots 23 of the remaining loading trough 4. The material of the spring tongue 21 is thin enough to resiliently yield to pressure. In this case, the spring tongue 21 thickened at its free end via a ramp 22, wherein the relevant function in connection with FIG. 6 will be described.
    Fig. 4 shows a further perspective view of the gun part of FIG. 1 obliquely from the front, wherein it is clear that the loading trough 4 is pivoted about the axis 15 laterally down and the shutter 1 is advanced accordingly. The free end 11 of the control element 6 is pivoted about the axis 20 below the closure 1.
    Fig. 5 shows another perspective view of the gun part of FIG. 1 from the front with advanced closure 1. In this case, the loading tray 4 is lowered. In the picture, the closure near end of the control element 6, while the Lademuldennahe end of the control element 6 is covered by the base plate 7.
    Once the shutter 1 is moved forward, the controls, which is rotatably mounted on the shaft 10 about the axis 20, moves through the shutter 1 and the loading tray dives down from, as shown in Figs. 4 and 5 is shown. The descent of the loading tray 4 takes place during slow closure of the shutter 1 exclusively by gravity, supported by the control element 6. When fast closing the loading tray 4 is forcibly controlled by the control 6 pressed down, because then the concave front 17 of the free end 11 the control element 6 abuts against the front side 18 of the loading trough. The only force to be overcome when closing the closure 1 is the spring force of the coil spring 9, which is kept low.
    When opening the shutter 1, the control 6 is released and pressed by the spring force of the coil spring 9 back to the starting position. As a result, the loading trough is raised by the control 6.
    Fig. 6 shows a cut at least in the loading tray side view with an inserted cartridge 30. A small caliber cartridge 30 is a rimfire cartridge. The rear edge 31 has a larger diameter than the rest of the cartridge 30. There, it is advantageous if the loading trough 4 has a spring-loaded nose 22 in the front region. Thus, it is possible that the cartridge 30 can be pushed with its shaft part absolutely centric in the camp. The height of the nose 22 is the difference of the diameter of the cartridge to the diameter of the rim 31. Thus, the cartridge 30 is centered on. When advancing the cartridge 30, the edge runs over the ramp 22, which forms the said nose. At this time, the cartridge is already in large part in the cartridge chamber, so it is guided directly and leads to the fact that the edge 31 presses the resilient nose 22 by the height of the edge 31 down. If such a nose 22 is omitted in a simpler embodiment, such as the spring tongue 21, it may happen that the projectile 30 is slightly damaged during insertion, or the applied bullet fat is stripped on one side. In addition, the insertion of the cartridge 30 in the camp can make much more difficult and jerky. If this nose 22 rigid, in conjunction with a rigid loading tray 4, you could push the cartridge 30 by hand only so far in the camp until the edge 31 of the cartridge 30 abuts the nose 22.
    Fig. 7 shows another perspective view of the gun part of FIG. 6 from above and obliquely from the front. In this case, the spring tongue 21 can be seen, which is framed by the two slots 23. The material of the spring tongue 21 is made thinner in this area.
    Fig. 8 shows a further cut at least in the loading tray 4 side view with the control 6, which is shown isolated. It can be seen that the charging trough 4 associated free end 12 projects obliquely upwards from the shaft 10 and is present at a right angle to the lower surface 14. An angle close to 90 degrees has the advantage that the control element 6 without force exerted as a spring tension, the movement of the loading tray 4 downward inhibits until the back 27 of the other free end 11 is pushed by a front side of the closure 1 from the rest position. The rest position is achieved by applying a spring tension, which is mediated by the spring 9. It is still shown in connection with FIG. 12 that the stop lug 27 defines the rest position by a stop against the closure housing 2. The angle between the two free ends is between 15 and 45 degrees. It is dependent on the axial position of the shaft 10. This can also be arranged further back in the direction of the closure 1.
    FIG. 9 shows a plan view of the loading trough 4 and the rifle part according to FIG. 1. It can be seen that the closure near the free end 12 is arranged substantially centrally to the closure 1 in its diameter in plan view, while the other free end 11 is arranged closer to the holder 5. Thus, a smaller pivoting of the rounded end 13 of the free end 11 is sufficient to release the loading tray 4 for a larger stroke for pivoting down. The spring tongue 21 is arranged centrally in the loading trough 4 and takes here about a quarter of the length of the loading trough 4 at. This length depends on the suspension of the spring tongue 21.
    Fig. 10 shows a front view of the loading trough 4 and rifle parts behind it according to FIG. 1. In addition to the central free end 11, the free end 12 arranged therefrom can be seen here, whose rounded tip 13 from below against the loading trough 4th pushes. The spring 9 is supported on the free end 12.
    11 shows a perspective side view of the loading trough 4 with an inserted small caliber cartridge 30 with the thickened rear edge 31.
    10 finally shows the elements of FIG. 10 obliquely from below with a clamped shaft 10. The shaft 10 is inserted in a recess of a base 25 in two opposite holes in this base 25. The stop lug 19, which is aligned in the same direction as the closure near the free end 11, abuts in the rest position against the base plate 7 and is held by the spring bias of the spring 9. In the same way, in another embodiment, it could also encounter the said base 25.
