Abstract
A capsule holder for retaining a mixing capsule on a rotary mixing device includes a carrier plate 10, an actuator disk 11 rotatable relative to the plate, and two retaining arms 12, 13 for clamping the capsule from opposite sides, the retaining arms having driving pins 22 engaging spiral cam slots 26 of the actuator disk 11. By rotating the actuator disk 11, the retaining arms 12, 13 are moved away from, or toward, each other. The thus constituted gearing is self-locking in one direction of force transmission so that centrifugal forces exerted on the retaining arms 12, 13 during rotation cannot move the arms apart. On the other hand, the retaining arms 12, 13 are opened with little effort by rotating the actuator disk 11.
Claims5
A capsule holder for a rotary mixing device, the capsule holder comprising:
- a carrier portion adapted to be coupled to a rotary part of the mixing device,
- a pair of retaining members movable relatively to each other along a capsule clamping direction and disposed on said carrier portion for engaging a capsule from two opposite sides along said clamping direction, and
- an actuator member mounted on said carrier portion for movement relative to said carrier portion and to both of said retaining members,
- said actuator member including guide means for at least one of said retaining members, said guide means extending at an angle with respect to both the direction of movement of said actuator member and said clamping direction, movement of said actuator member relative to said carrier portion causing both of said retaining members to move relative to each other and to said actuator member.
A capsule holder for a rotary mixing device, the capsule holder comprising:

- a pair of retaining members movable relatively to each other along a capsule clamping direction and disposed on said carrier portion for engaging a capsule from two opposite sides along said clamping direction, and
- an actuator member mounted for rotation relative to said carrier portion about a common axis and being in engagement with at least one of said retaining members through guide means which extends at an angle with respect to both the direction of movement of said actuator member and said clamping direction, rotation of said actuator member relative to said carrier portion causing both of said retaining members to move relative to each other and to said actuator member.
