Description
- 1. Field of the Invention
- The present invention relates to a cartridge magazine which is used, e.g., with powder charge-operated bolt setting tools and which has a carrier member having a plurality of receptacles for frictionally retaining therein propellant-containing cartridges that serve as drive means, and means provided in each of the plurality of receptacles for formlockingly retaining respective cartridges from displacement in an axial direction of cartridge.
- 2. Description of the Prior Art
- U.S. Pat. No. 6,052,455 discloses storing of propellant-containing cartridges in a strip-shaped cartridge magazine. To this end, a carrier member is provided with a plurality of equidistantly spaced from each other receptacles in which cartridges are frictionally retained. The receptacles are arranged in nose-shaped, projecting to one side of the cartridge magazine elevations. In the receptacles, there is provided a step that serves as a stop for a toric widening of a cartridge and formlockingly retains the cartridge from displacement in the axial direction of the cartridge.
- The drawback of the known cartridge magazine consists in that upon a position-dependent deformation of the plastic material of the cartridge magazine the cartridges are not frictionally retained therein and can fall out of the magazine.
- Accordingly, an object of the present invention is to provide a cartridge magazine with which a reliable retaining of cartridges in the receptacles is insured and inadvertent falling out of a cartridge from a receptacle is reliably prevented.
- This and other objects of the present invention, which will become apparent hereinafter, are achieved by providing, in each of the receptacle further means for formlockingly retaining respective cartridges from displacement in a second axial direction of the cartridges opposite the first axial direction.
- The further means reliably prevents falling of the cartridges out of the receptacles even when the friction between receptacles and the cartridges is reduced or eliminated due to outside influences, e.g., climate conditions.
- Advantageously, the further formlockingly retaining means includes at least one projection for each of the receptacles for engaging from behind a cartridge bottom of a respective cartridge and forming a stop. Such projections can be formed in an already existing cartridge member without any noticeable additional expenses.
- It is further advantageous when the first-mentioned formlockingly retaining means is formed by a step that serves as a stop for a toric widening of a cartridge. The step can be provided on an inner circumference of a receptacle.
- Advantageously, two projections, which located opposite each other, are provided on a rim of a receptacle. This insures an optimal retention of a cartridge in the receptacle. Of course, more than two projections can be provided in a receptacle.
- In a still further advantageous embodiment of the present invention, the at least one projection is formed as an embossed or calked member. The projection can be formed by embossing or calking an elevation provided on the carrier member after placing of cartridge, which insures an economical manufacturing.
- In accordance with another advantageous embodiment of the present invention, the at least one projection is formed as a pivotal snap or locking element. This insures that the carrier member can be filled with cartridges several times, i.e., provides for a multiple use of the carrier member. The snap or locking element is formed integrally with the carrier member, e.g., from a plastic material by an injection-molding process.
- In accordance with yet another advantageous embodiment of the present invention, the at least one projections is formed as a floating clip that surrounds a receptacle, e.g., by 360°. Alternatively, the clip can be formed of several members provided on a rim of a receptacle. With this embodiment, the carrier member can be easily equipped with cartridges, as the floating clip serves as a snap element. Advantageously, the floating clip is formed integrally with the carrier member, e.g., from a plastic material by injection-molding.
- The novel features of the present invention, which are considered as characteristic for the invention, are set forth in the appended claims. The invention itself, however, both as to its construction and its mode of operation, together with additional advantages and objects thereof, will be best understood from the following detailed description of preferred embodiments, when read with reference to the accompanying drawings.
- The drawings show:
-
FIG. 1 a plan view of a cartridge member of a cartridge magazine according to the present invention before placing of cartridges therein; -
FIG. 2 a cross-sectional view of the carrier member along line II-II inFIG. 1 ; -
FIG. 3 a cross-sectional view similar to that ofFIG. 2 but with cartridges placed in the cartridge carrier; -
FIG. 4 a plan view of a cartridge member with cartridges placed therein of a further embodiment of a cartridge magazine according to the present invention; -
FIG. 5 a cross-sectional view along line V-V inFIG. 4 ; and -
FIG. 6 a plan view of a cartridge member of another embodiment of a cartridge magazine according to the present invention. -
FIGS. 1 through 3 show acarrier member 20 of a strip-shaped cartridge magazine 10 that is formed of a plastic material and has a plurality of equidistantly spaced from each other, arranged one after another,receptacles 21 for propellant-filled cartridges 11 (FIG. 3 ). In each of thereceptacle 21, there is provided astep 22 that serves as a stop for atoric widening 14 of acartridge 11. The stop is designed to formlockingly retain thecartridge 11 in a predetermined axial direction defined by a cartridge axis A and anopening zone 13 of thecartridge 11. In thereceptacle 21, which is surrounded, at least regionwise by acylindrical wall 26, acartridge 11, which projects to one side of thecarrier member 20, is frictionally retained. - On the side of the
carrier member 20 remote from thewall 26, there is provided a projection 23 (seeFIG. 3 ) that engages from behind the toric widening 14 of thecartridge 11 in the region of thecartridge bottom 12 to formlockingly retain thecartridge 11 in a direction opposite the direction of the axial extent of the cartridge 11 (in the direction of the cartridge bottom 12). Thus, thecartridges 11 are formlockingly held by stops in both axial directions. Thereby, falling out ofcartridges 11 from thecarrier member 20 is prevented when the frictional connection between thecartridges 11 and thereceptacles 21 is reinforced by external means such as, e.g., kinematic means. - The
projections 23 are formed in thecarrier member 20, which is shown inFIGS. 1-3 and which is a plastic injection-molded part, by side-shaped elevations 25 upon injection-molding of the carrier member (seeFIGS. 1-2 ). After thecartridges 11 have been placed in thereceptacles 21, theelevations 25 are transformed into theprojections 23 by embossing or calking, engaging from behind thecartridges 11 on theirbottom 12. (FIG. 3 ). - Sidewise of the
carrier member 21, these are providedtransportation recesses 24 in which a transporting element of a setting tool or of a magazine receptacle of the setting tool, or the like can engage for displacing thecartridge magazine 10. -
FIGS. 4-5 show another embodiment ofcartridge magazine 10 that differs from that shown inFIGS. 1-3 in thatprojections 23 are formed as pivotal snap or locking elements. The snap elements can be formed directly on the carrier member during an injection process for forming the carrier member. A subsequent calking is not any more necessary. After the carrier member has been formed, thecartridges 11 can be placed in thereceptacles 21, with the snap elements being bent out outwardly by the cartridges. To this end, on a side of the snap element remote from the receptacle, afree space 27 is provided. When thecartridge 11 is completely inserted in thereceptacle 21, the snap element pivots back into its initial position, engaging regionwise thebottom 12 of thecartridge 11. Advantageously the snap elements have a shape of a segment of a circle and partially surround therespective receptacles 21. - In the
cartridge magazine 10 shown inFIG. 6 , theprojections 23 are formed as floating clips surrounding thereceptacles 21 by 360°. The floating clip can be formed on a carrier member during the injection process when thecarrier member 21 is formed. Alternatively, instead of floating clips which completely surround the receptacles, one or more members of the floating clip can be provided at thereceptacle 21. - Though the present invention was shown and described with references to the preferred embodiments such are merely illustrative of the present invention and are 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 embodiments 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.
