SLIDE COVER PLATE FOR THE SLIDE OF A STRIKER-FIRED HAND GUN

The present invention relates to a slide cover plate for the slide of a striker-fired hand gun, closing the end of the slide being opposite to the muzzle and provides support for an end of a spring striker unit and/or for an end of an spring extractor unit inside of the slide, the slide cover plate is pushed into a groove of cross direction to the longitudinal axis of the slide and formed in the end of the slide, where the slide cover plate is fixed in its terminal position.

There are known striker-fired hand guns with a slide comprising firing structure and also other spring elements and at the back end of the slide a planar formed slide cover plate is provided. This can be pushed into a groove from the lower side. Reaching its end position this slide cover plate constitutes a base support for spring striker unit and for a spring extractor unit or other spring elements.

Among such striker-fired hand guns including slide cover plate is the Glock family as the one of most common can be mentioned, and also their clones.

The aspect of the present utility invention is to create a slide cover plate, which is fitting with the standard groove of the slide. In order to provide further functions for the slide cover plate, we intended to scale up the slide cover plate in its size. Further aspect was that when the new slide cover plate is glided into the groove it can be fixed in its terminal position, i.e. let it be changeable. For this purpose it is necessary a special form design to allow pushing by tools the spring elements at least and especially the end of the spring striker unit during mounting. In lack of this feature the spring strained end would prevent fixing the slide cover plate in its terminal position.

It has been disclosed that an improved slide cover plate can be applicable to provide an increased area. This means a possible area enhancement from two directions: side direction with“side wings” and upwards upgrading the measures on the top of the slide until not to prevent the rear sight. As to the function of the slide cover plate its low line in its final position will not extend lower than the original slide cover plate.

The side cover plate of the opening paragraph in in its most general embodiment according to this invention, the slide cover plate comprises a backwardly protruding part having larger face area than the cross outline area of the slide at its end, and the slide cover plate comprises a hollow section, which forms a recess for reaching the end of the spring striker unit and/or the end of the spring extractor unit by tool when the slide cover plate being pushed into the groove but is in an intermediate position different from the terminal position, said hollow section and recess are extending behind the face area of the backwardly protruding part in the direction of the longitudinal axis of the slide.

The improved slide cover plate according to the present invention is preferably of a single piece - i.e. metal, cast technology - and provide a surface applicable for different purposes. Such as, among others, for bearing subtitles, logos, or as small light emission devices. The side wings may be promote or ease the grip of the slide, essentially when perfected by thumb and index finger. The upward protruding area size enhancement will not cause problem with wearing and getting out, the overall measures will not increase. The increased area will cause under some circumstances single hand loading.

The slide cover plate according to the present invention is preferably can be of the kind containing a striker pin indicator. This can be a borehole and a pin being movable in that. In this way the user can easily control the state of the gun.

The invention will be illustrated in figures in the following, whereby:

Fig. 1 is a known striker-fired hand gun with an original slide cover plate, in perspective view,

Fig. 2 is hand gun according to Fig. 1 with the slide cover plate of the present invention,

Figs. 3-5 are the hand gun according to Fig. 1 with the slide cover plate of the present invention, in different pushing states,

Fig. 6 is hand gun according to Figs. 3-5 with the new slide cover plate, in phase before pushing,

Fig. 7 is the slide with half pushed slide cover plate, in partly enhanced view,

Fig. 8 is the slide with fully pushed slide cover plate, in partly enhanced view,

Fig. 9 is the slide with fully pushed slide cover plate, in upward view.

Fig. 1 is a known striker-fired hand gun with an original slide cover plate, in perspective view, according to the state of the art. In the slide 2 the closing the end 4 being opposite to the muzzle 3 an original slide cover plate 1 ST is closing. This is at the same time provides support for an end 11 of a spring striker unit 5 and/or for an end 21 of a spring extractor unit 15 inside of the slide 2. The original slide cover plate 1 ST is pushed from downside into a groove 7 being of cross direction to the longitudinal axis 6 of the slide 2. For this operation an appropriate tool is necessary to compress the spring(s), preferably on the ends 1 1 and/or 21 , and then keep pushing above the ends 1 1 and/or 21 .

Fig. 2 is illustrating the same hand gun as seen in Fig. 1 , having a difference with accordance of the object of the present sample, that the original slide cover plate

I ST has been replaced by a new slide cover plate 1 . In this situation the end 1 1 and/or 21 could not be reached in case the slide cover plate 1 is larger even in the direction of push, because the reach by tool would be impossible.

The above mentioned facts are illustrated in Figs. 3-6 from a different view.

Fig. 3 shows end 4 of slide 2 and the original slide cover plate 1 ST in back view.

Fig. 4 shows in similar back view the end 4 of the slide 2 and end the slide cover plate 1 of the present invention to be pushed. Flere the replacement slide cover plate 1 . Flere the new slide cover plate 1 comprises a backwardly protruding part 9 having larger face area 17 than the cross outline area of the slide 2 at its end 4. The backwardly protruding part 9 further may comprise an upright protruding elevated rim 16, and two side wings 14 for enhanced grip on the slide. In this embodiment the wings together with the upright protruding elevated rim 16 form together a rounded corner square as said face area 17. The backwardly protruding part 9 may constitute a face area 17 bearing text and/or logo.

Fig. 5 returns to the original slide cover plate 1 ST which is in an intermediate position 10. To move further a tool is necessary to push end 1 1 and then end 21 .

Fig. 6 shows that the original slide cover plate 1 ST is in at final position 8 the push movement has been finished.

Fig. 7 shows the slide 2 with half pushed slide cover plate, in partly enhanced view. A recess 13 can be seen, through which the ends 1 1 and 21 can be pushed inwardly. In Fig. 8 the slide cover plate 1 is in its final position 8.

Fig. 9 is the slide 2 with fully pushed slide cover plate 1 , in upward view. There can be viewed that the backwardly protruding part 9 comprises a larger face area 17 than the cross outline area of the slide 2 at its end 4. It is also illustrated, that the slide cover plate 1 comprises a hollow part 12, which forms a recess 13 for reaching the end

I I of the spring striker unit 5 and/or the end 21 of the spring extractor unit 15 by tool when the slide cover plate 1 being pushed into the groove 7 but is in an intermediate

position 10 different from the terminal position 8, said hollow section 12 and recess 13 are extending behind the face area 17 of the backwardly protruding part 9 in the direction of the longitudinal axis 6 of the slide 2.

The slide cover plate 1 of the present invention can be evaluated in one single piece for example by moulding. In another embodiment the backwardly protruding part 9 is carrying on its face area 17 some light emitting display means.

In an embodiment the backwardly protruding part 9 may comprise a striker pin indicator. The striker pin indicator can be a borehole 18 and a pin 19 being movable in that. The pin 19 can be protruding and/or conspicuous in its colour.

The slide cover plate 1 of the present invention can be used in certain airsoft guns and airguns, if the respective parts are removable in those guns. The existence, location, function of the mentioned spring elements may be different from that of the corresponding ones in real firearms.

The slide cover plate 1 of the present invention can be comprising a dedicated electronic RFID identification tag for promoting quick and easy identification of guns, or any other kind of dedicated electronic chip with electric power source. In this latter case different goals can also be achieved, such as, for e.g., logging number and time of shots. This can be realised using integrated accelerometer and clock. These features may be advantageous among others in case of duty pistols where the identification is necessary before and after duty, and logging during duty. The corresponding RFID identification tag or the dedicated electronic chip with electric power source may be moulded inside, glued or mechanically attached to the slide cover plate 1 . The RFID identification tag in one embodiment is comprising a programmable RFID identification chip.

The advantage of the present invention is a simple and easily manufactured element, which is quickly rechargeable and reliably placed instead of the original one. Furthermore it provides usable space for special clips, for e.g. pockets or belts.
