Definitions

  • 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.
  • U.S. Pat. No. 6,052,455 discloses storing of propellant-containing cartridges in a strip-shaped cartridge magazine.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • more than two projections can be provided in a receptacle.
  • 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.
  • 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.
  • the at least one projections is formed as a floating clip that surrounds a receptacle, e.g., by 360°.
  • the clip can be formed of several members provided on a rim of a receptacle.
  • the carrier member can be easily equipped with cartridges, as the floating clip serves as a snap element.
  • the floating clip is formed integrally with the carrier member, e.g., from a plastic material by injection-molding.
  • 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 in FIG. 1 ;
  • FIG. 3 a cross-sectional view similar to that of FIG. 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 in FIG. 4 ;
  • 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 a carrier 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 ).
  • a step 22 that serves as a stop for a toric widening 14 of a cartridge 11 .
  • the stop is designed to formlockingly retain the cartridge 11 in a predetermined axial direction defined by a cartridge axis A and an opening zone 13 of the cartridge 11 .
  • a cartridge 11 which projects to one side of the carrier member 20 , is frictionally retained.
  • a projection 23 (see FIG. 3 ) that engages from behind the toric widening 14 of the cartridge 11 in the region of the cartridge bottom 12 to formlockingly retain the cartridge 11 in a direction opposite the direction of the axial extent of the cartridge 11 (in the direction of the cartridge bottom 12 ).
  • the cartridges 11 are formlockingly held by stops in both axial directions.
  • the projections 23 are formed in the carrier member 20 , which is shown in FIGS. 1-3 and which is a plastic injection-molded part, by side-shaped elevations 25 upon injection-molding of the carrier member (see FIGS. 1-2 ). After the cartridges 11 have been placed in the receptacles 21 , the elevations 25 are transformed into the projections 23 by embossing or calking, engaging from behind the cartridges 11 on their bottom 12 . ( FIG. 3 ).
  • transportation recesses 24 are provided sidewise of the carrier member 21 , which a transporting element of a setting tool or of a magazine receptacle of the setting tool, or the like can engage for displacing the cartridge magazine 10 .
  • FIGS. 4-5 show another embodiment of cartridge magazine 10 that differs from that shown in FIGS. 1-3 in that projections 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.
  • the cartridges 11 can be placed in the receptacles 21 , with the snap elements being bent out outwardly by the cartridges.
  • a free space 27 is provided on a side of the snap element remote from the receptacle.
  • the snap element pivots back into its initial position, engaging regionwise the bottom 12 of the cartridge 11 .
  • the snap elements have a shape of a segment of a circle and partially surround the respective receptacles 21 .
  • the projections 23 are formed as floating clips surrounding the receptacles 21 by 360°.
  • the floating clip can be formed on a carrier member during the injection process when the carrier member 21 is formed.
  • one or more members of the floating clip can be provided at the receptacle 21 .
