Oyster opening device

摘要

Disclosed is an oyster shucking device, of which both manual and automated embodiments are envisioned. An exemplary embodiment is constructed of aluminum and/or stainless steel and may be mounted on a wooden, steel or plastic base. A double roller bearing arrangement housed in a bearing box above a spike and positioning cylinder generates an efficient transfer of an actuation force to an oyster hinge while providing a user with the ability to adjust the amount of force applied to the oyster. Additionally, the spike and positioning cylinder arrangement provides for consistent and stable alignment of the spike all the way through a stroke. Further, the vertical travel of the spike as guided by the positioning cylinder provides for a wide range of travel by the spike to accommodate various oyster sizes without having to reconfigure or adjust the setup of the device.

主权项

1. An oyster opening device, the oyster opening device comprising:
a base; a substantially vertical back post; a curved handle; a spike component having a pointed end; a bearing box comprising a pair of roller bearings in contact with the curved handle; and a positioning cylinder; wherein:
the substantially vertical back post is anchored to the base;the positioning cylinder extends over the base from an upper portion of the substantially vertical back post;the curved handle is mechanically fixed to the substantially vertical back post via a hinge such that the handle is operable to raise and lower;the bearing box is mechanically fixed to the spike at an upper end opposite the pointed end;the spike extends through the positioning cylinder such that the spike is substantially perpendicular to the base and parallel to the back post; andthe curved handle extends through the bearing box such that when the curved handle is raised or lowered the spike is also raised or lowered.
