A frame (2) for a loudspeaker cabinet (1) comprising a connection device (21) for connecting to another loudspeaker cabinet, said connection device (21) comprising a eyelet (210) and a locking system (3), said locking system (3) comprising:
- two legs, which are a front leg (31a) and a back leg (31b), disposed parallel to each other and each comprising a lower aperture (311) and an upper aperture (312);
- a slide (32) disposed between the two legs (31a;
- 31b) and configured to slide between a high position and a low position, the slide (32) comprising an opening (323) having at least one wide portion (323a) and at least one narrow portion (323b), and being provided with two guide members (321), each bearing on an edge (313) of at least one of the two legs (31a;
- 31b) on opposite sides of the leg;
- at least one spacer (39) linking the two legs (31a;
- 31b) to each other;
- a first elastic member (33) connected to said slide (32) and configured to bring the slide (32) automatically from the high position to the low position;
- a selecting screw (34) comprising a shaft (341) having at least one wide section and at least one narrow section, the shaft (341) of the selecting screw (34) passing through the upper aperture (312) of each of the legs (31a;
- 31b) and the opening (323) of the slide (32), and being configured to move between a returned position in which the at least one wide section of the shaft (341) is inside the opening (323) of the slide (32) and a moved away position in which the at least one narrow section of the shaft (341) of the screw is inside the opening (323) of the slide (32);
- a second elastic member (342) connected to the selecting screw (34) and configured to return the selecting screw (34) automatically from the moved away position to the returned position;
- a locking member comprising a locking shaft (35) configured to take a locking position in which the locking shaft (35) passes through the lower aperture (311) of each of the two legs (31a;
- 31b) and an opening position in which the locking shaft (35) frees at least partly a space (E) defined between the two legs (31a;
- 31b);
- an actuator (38) configured to take a pulled position and a pushed position and joined to the selecting screw (34) and to the locking shaft (35),
- said locking system (3) being configured to take a locked configuration wherein:
- the slide (32) is in high position;
- the selecting screw (34) is in returned position in which the wide section of the shaft (341) is inside the wide portion (323a) of the opening (323) of the slide (32);
- and
- the locking shaft (35) is in locking position;
- and a cocked configuration in which:
- the slide (32) is in low position;
- the selecting screw (34) is in moved away position in which the narrow section of the shaft (341) is inside the opening (323) of the slide (32);
- and
- the locking shaft (35) is in opening position,
- the locking system (3) passing from the locked configuration to the cocked configuration by movement of the actuator (38) and from the cocked configuration to the locked configuration by movement of the slide (32) from the low position to the high position.
