Abstract
A hand-held, rotary fabric cutter includes a handle having a blade end and a grip end opposite the blade end configured to be held by a user to support the cutter during use of the cutter to cut a piece of fabric, a rotary blade, and a blade retention system. The rotary blade is configured to be coupled to the blade end of the handle to rotate about an axis. The blade retention system is configured to selectively couple the rotary blade to the handle.
Claims16
A hand-held, rotary fabric cutter comprising:
- a handle having a blade end and a grip end opposite the blade end configured to be held by a user to support the cutter during use of the cutter to cut a piece of fabric,
- a rotary blade configured to be coupled to the blade end of the handle to rotate about an axis, and
- a blade retention system configured to selectively couple the rotary blade to the handle, the blade retention system comprising
- a blade fastener configured to change between a secured position in which the blade fastener extends axially through the rotary blade into the blade end of the handle to secure the rotary blade to the handle and a released position in which the blade fastener has moved away from the handle to allow access to the blade,
- a quick release mechanism configured to change between a locked configuration in which movement of the blade fastener relative to the handle is blocked when the blade fastener is in the secured position and an unlocked configuration in which movement of the blade fastener away from the handle is permitted, and
- at least one magnet coupled to the blade end of the handle, wherein the at least one magnet is located between the rotary blade and the blade end of the handle, the at least one magnet configured to apply a magnetic force to the rotary blade to draw the rotary blade to the blade end of the handle so that the rotary blade remains coupled to the blade end of the handle when the blade fastener is in the released position.

- wherein the handle comprises:
- a handle body, and a retractable blade guard coupled to the handle body to define a portion of the blade end of the handle and slidable relative to the handle body between a guard position in which the blade guard blocks access to a blade edge of the rotary blade and a retracted position in which the blade guard has moved away from the blade edge of the rotary blade so that the blade edge is exposed to cut the piece of fabric, wherein the at least one magnet is located between the handle body and the retractable blade guard and configured to move with the blade guard between the guard position and the retracted position.
