Claims14
A retainer (100) adapted for catching ejected cartridge cases (14) from shotguns (10), said retainer (100) comprising:
- a base (110) adapted for being mounted on a shotgun (10);
- and
- an elongate member (120) configured for releasable fastening to said base (110);
- wherein the elongate member (120) comprises:
- a core (122) of one or more magnets (123);
- and
- a cover (124) configured for covering said core (122) of one or more magnets (123),
- wherein the one or more magnets (123) comprise a plurality of permanent magnets arranged in an arrangement of the plurality of magnets so as to form a relatively weak magnetic field on a first side face (126) of the cover (124) of the elongate member (120), and a relatively strong magnetic field on a second, opposite side face (127) of the cover (124) of the elongate member (120), and wherein the relatively strong magnetic field is facing away from the base (110), wherein the plurality of permanent magnets are arranged as a Halbach array, wherein the cover (124) is configured with a rounded top face (128) so that the first side face (126), the second, opposite side face (127), and the rounded top face (128) combine to cover the plurality of magnets.
