Abstract
A blade mounting and removal tool, and system, for safely removing a blade from a blade axle of a food product slicer. The blade axle includes a multi-axis locking system for securing the blade to the blade axle. The blade removal tool includes a tool base, a blade engagement assembly, and a blade unlocking assembly. The blade engagement assembly is attached to the tool base and has a blade engagement actuator cooperating with at least one blade engagement retainer. The blade unlocking assembly is also attached to the tool base and has a blade unlocking actuator cooperating with a blade unlocking post.
Claims24
A safety blade mounting and removal system for a product slicer, comprising:
- a blade (600) having a hub (610), a hub aperture (618), and at least one hub engagement protrusion (614) extending into the hub aperture (618);
- a blade axle (700) having a multi-axis locking system for securing the blade (600) to the blade axle (700), wherein:
- A) the multi-axis locking system includes a biased blade locking assembly (730) and a blade mount (740) having at least one mount channel (742) with an axial aspect (743) and a rotational aspect (745);
- and
- B) the at least one mount channel (742) cooperates with the at least one hub engagement protrusion (614) and alignment of the at least one hub engagement protrusion (614) with the at least one mount channel (742) permits the at least one hub engagement protrusion (614) to:
- (i) translate axially in the at least one mount channel (742) an axial translation distance (744) at an axial translation position, and
- (ii) achieve relative rotational movement with respect to the blade mount (740) within the at least one mount channel (742), about a blade center, a rotational distance (746) allowing the biased blade locking assembly (730) to engage a receiver (620) in the blade (600) or the_hub (610), wherein the biased blade locking assembly (730) is located at an engagement angle (738) from the axial translation position, establishing a blade operating position, and thereby prevent movement of the at least one hub engagement protrusion (614) within the at least one mount channel (742) until the biased blade locking assembly (730) is disengaged from the receiver (620);
- a blade removal tool (100) having:
- A) a tool base (200);
- B) a locking assembly release (510) attached to the tool base (200) and sized to cooperate with the receiver (620) and the biased blade locking assembly (730) to release the biased blade locking assembly (730) from the receiver (620) when the blade removal tool (100) engages the blade (600);
- C) a blade engagement assembly (300) attached to the tool base (200) and having a blade engagement actuator (310) cooperating with at least one blade engagement retainer (330), wherein:
- (i) relative movement of the blade engagement actuator (310) with respect to the tool base (200) from a blade engagement actuator initial position (311) to a blade engagement actuator retaining position (312) produces movement of the at least one blade engagement retainer (330) from a retainer initial position (336) to a retainer retaining position (338) whereby at least a portion of the blade engagement retainer (330) has engaged the hub (610) or blade (600) to interlock the tool base (200) and the blade (600);
- D) a blade unlocking assembly (400) attached to the tool base (200) and having a blade unlocking actuator (410) cooperating with a blade unlocking post (430), wherein:
- (i) relative movement of the blade unlocking actuator (410) with respect to the tool base (200) from a blade unlocking actuator initial position (411) to a blade unlocking actuator release position (412) produces rotation of the blade unlocking post (430) from a post initial position (431) to a post release position (432);
- (ii) the blade unlocking post (430) cooperates with the blade mount (740) so that rotation of the blade unlocking post (430) produces rotation of the blade mount (740) with respect to the blade (600) and associated movement of the at least one hub engagement protrusion (614) within the at least one mount channel (742) from the blade operating position to re-align the at least one hub engagement protrusion (614) with the axial translation position and permit the blade (600) to be axially pulled, with the blade removal tool (100), from the blade mount (740);
- and
- (iii) the blade engagement assembly (300) and the blade unlocking assembly (400) cooperate so that relative movement of the blade unlocking actuator (410) cannot occur unless the blade engagement actuator (310) is in the blade engagement actuator retaining position (312), and relative movement of the blade engagement actuator (310) cannot occur when the blade unlocking actuator (410) is in the blade unlocking actuator release position (412), thereby requiring sequenced movement of both the blade engagement actuator (310) and the blade unlocking actuator (410) to secure the blade (600) to the removal tool (100) and remove the blade (600) from the slicer, and requiring sequenced movement of both the blade engagement actuator (310) and the blade unlocking actuator (410) to release the blade (600) from the removal tool (100).
