DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A strip-shaped cartridge magazine 10 according to the present invention, which is shown in FIGS. 1-3, has a carrier member 20 that extends in a longitudinal direction L and is formed of a plastic material. The carrier member 20 has a plurality of arranged one after another, equidistantly spaced from each other, receptacles 21 for cartridges 11 filled with propellant (FIGS. 2-3). In each receptacle 21, there is provided a step 22 that serves as a stop for a toric widening 14 of a cartridge 11 for formlockingly retain the cartridge 11 in an axial direction defined by a cartridge axis A and an opening zone 13. The cartridge 11 is further frictionally held in the receptacle 11 which is surrounded, at least partially by cylindrical walls 26 that project from the carrier member 20 on one side of the carrier member 20.

On a flat side 23 of the carrier member 20 remote from the walls 26, there is provided a recess 27 extending in the longitudinal direction L of the carrier member 20. The recess 27 limits longitudinal ribs 28 which are formed as bordering elevations and which extend on both longitudinal sides of the carrier member 20 in the longitudinal direction. At a first, in the longitudinal direction L, end 31 of the carrier member 20 which is formed as a conically tapering end, the recess 27 is likewise limited by an approximately parabolic elevation that corresponds in shape to the first end 31 and forms a rib 29 that passes smoothly on both sides of the carrier member 20 into longitudinal ribs 28.

Sidewise on the carrier member 21, there are formed, in the longitudinal ribs 28, transportation recesses 24 into which a transporting element of a setting tool or of a magazine receptacle can engage in order to displace the cartridge magazine 10. The transportation recesses 24 are closed toward the recess 27.

For securing the cartridges 11 in the receptacles 21, there is provided, in the recess 27 in an axial direction remotely from the opening zone 13, a cover strip 30 that is formed as a self adhesive foil. The cover foil 30 is glued to both cartridge bottoms 12 of the cartridges 11 and to the surface of the carrier member 20 located in the recess 27. The cover strip 30 or the self-adhesive foil is formed, e.g., as a polyester or acrylate foil with a high climatic and heat-resistance and which is coated with a special glue such as, e.g., a modified acrylic adhesive or glue that insures a good bonding with low-energy surfaces (such as, e.g., of polypropylene (PP) used as a material of the carrier member 20) without lubrication or slightly lubricated.

With the cover strip 30 being arranged in the recess 27, the strip 30 is protected from a mechanical damage, and is prevented from inadvertently becoming loose as a result of contact with the transporting element or the like, and from causing a malfunction in the setting tool, e.g., blocking the displacement of the magazine strip.

At the second, in the longitudinal direction L, end 32 of the carrier member 20 where no bordering elevation is available, the cover strip does not extend completely to the second end 32. This can also take place at the first end 31 when, e.g., no rib should be provided there.

Though the present invention was shown and described with references to the preferred embodiment, such is merely illustrative of the present invention and is not to be construed as a limitation thereof and various modifications of the present invention will be apparent to those skilled in the art. It is therefore not intended that the present invention be limited to the disclosed embodiment or details thereof, and the present invention includes all variations and/or alternative embodiments within the spirit and scope of the present invention as defined by the appended claims.

Claims

1. A cartridge magazine, comprising a carrier member (20) having a plurality of receptacles (21) for receiving propellant-containing cartridges (11), a recess (27) formed in a flat surface (23) of the carrier member (20) and extending in a longitudinal direction (L), and longitudinal ribs provided on longitudinal sides of the recess (27) and limiting same; and a cover strip (30) for securing the cartridges in the receptacles and located in the recess (27).

2. A cartridge magazine according to claim 1, wherein the cover strip is formed as a self-adhesive foil.

3. A cartridge magazine according to claim 1, wherein the cover strip (30) is formed by an adhesive-coated foil formed of a material selected from the group containing polyester and acrylate.

4. A cartridge magazine according to claim 1, wherein the recess (27) is limited at a first, in the longitudinal direction, end (31) of the carrier member (20) by a rib (29) that follows a profile of the first end (31).

5. A cartridge magazine according to claim 1, wherein the cover strip (30) is spaced from a second, in the longitudinal direction (L), end (32) of the carrier member (20).
