Definitions

  • the present application relates generally to the field of cutting devices for cutting patterns in sheet material.
  • Cutting devices may be used to cut a desired shape in sheet material. However, it may be difficult to consistently cut the desired shape with scissors or another similar hand-held tool.
  • a rotary blade and a template may also be used, but the rotary blade may be difficult to maneuver within the desired pattern.
  • a user may be required to adjust the rotary blade at least once before the cut is completed due to the desired shape. The rotary blade may also wander into the template as the cut is performed, damaging the template and/or the blade itself.
  • US 821681A discloses a combined straight-edge cutter and paper cutter having a frame or body with lugs or lips arranged to underlap flange portions on the straight-edge, so as to maintain it in sliding connection with the straight-edge and prevent it from lateral rock or tilt during use.

  • a cutting apparatus 10 is shown according to an exemplary embodiment.
  • the apparatus 10 shown in FIG. 1 is configured to facilitate making circular cuts in a sheet of material (e.g., a sheet of fabric).
  • the apparatus 10 may be configured to cut another desired (i.e., non-circular) shape in a sheet of material, including other symmetrical shapes such as an oval, hexagon, rectangle, triangle, and the like.
  • the apparatus 10 includes a cutting device 12 (e.g., carriage, cutting tool, etc.) and a cutting template 14 (e.g., board).
  • the cutting template 14 includes a flat top surface 16, a raised outer edge 18 bordering rear and side portions of the top surface 16, and a plurality of channels 20 (e.g., grooves, guides, etc.) formed in the top surface 16 and through the template 14.
  • Each of the channels 20 is configured to receive the cutting device 12.
  • the channels 20 are configured to guide the cutting device 12 around the circumference of the channel's 20 predetermined radius to make a circular cut.

  • the selected channel 20 is configured to guide the movement of the cutting device 12 from one end of the channel 20 to the other.
  • the movement of the cutting device 12 causes a semi-circular cut through both halves of the sheet material when a blade 34 (shown in FIG. 3 ) of the device 12 is extended, causing a wholly circular pattern to be cut within the material.
  • the channels 20 may be configured (e.g., shaped) accordingly.
  • the cutting device 12 of the apparatus 10 is shown according to an exemplary embodiment.
  • the cutting device 12 is configured to move between a first position (i.e., a retracted position) in which the blade 34 (e.g., rotary blade) is retracted within the device 12 (shown in FIGS. 2-4 ), and a second position (i.e., a cutting, extended, or exposed position) in which the blade 34 is projected from the device 12 to make a cut (shown in FIGS. 5-7 ).

  • the body 70 including the skirt 76 and the flange 72, may be a single piece.
  • the body 70 has an annular shape, having an opening formed therethrough that is configured to receive at least a portion of the base 22 (see FIG. 8 ).
  • the handle 24 also includes a cap 26 removably coupled to and covering an open top end of the body 70.
  • the cap 26 and a portion of the body 70 may each include corresponding threads configured to mate the cap 26 with the body 70.
  • the handle 24 is sized and shaped to enable a user of the apparatus 10 to grip the handle 24 while tracking the device 12 within the channels 20 of the template 14 when the device 12 is in the second position.
  • the skirt 76 for instance, has a smaller maximum diameter than the cap 26 or the flange 72, enabling a user to grip the handle 24 more easily at the skirt 76.
  • the skirt 76 is V-shaped, decreasing in diameter from a top end of the skirt 76 (i.e., at or near the cap 26) to the lower end of the skirt 76 (i.e., at the flange 72).
  • the handle 24 is configured to move axially relative to the base 22, along the vertical axis provided by the base 22.
  • a downward (e.g., compressive) force is applied to the handle 24 while the device 12 is in the first position (shown in FIG. 4 )
  • the blade 34 of the cutting device 12 is moved from the retracted position to the cutting position (as shown in FIG. 5 ).
  • a manual force may be applied by the user at the cap 26.
  • Downward movement of the handle 24 forces the blade cartridge 36 downward in the same direction as the handle 24, causing the blade 34 of the blade cartridge 36 to extend to the cutting position (as shown in FIGS. 5 and 7 ).
  • the cutting device 12 may be used to cut a desired pattern within a sheet of material.
  • the handle 24 is spring-loaded to return the device 12 (e.g., the blade 34) to the first position when the force is removed.
  • the base 22 has an annular disc shape, having an opening 32 formed through the center of the base 22 to allow the blade 34 to extend out from the base 22 to make a cut.

  • the chamfers 60 may aid in aligning (e.g., centering) the blade 34 within the corresponding channel 20 when the blade 34 is in the extended position within the channel 20.
  • the projections 30 and the channels 20 may have other complementary shapes configured to align the projections 30 (and the blade 34) within the channels 20.
  • the base 22 also includes a flat bottom surface 74 configured to interface with the top surface 16 of the template 14 when the projections 30 are positioned within one of the channels 20.
  • Tabs 28 are positioned opposite each other on a top side of the base 22. The tabs 28 are intended to assist the user in moving the cutting device 12 within the channels 20 by providing an indication of the direction of the blade 34 when the blade 34 is not visible (e.g., is positioned within one of the channels 20).
  • FIG. 8 shows a cross-sectional view of the cutting device 12 when the cutting device 12 is between the first and second positions (i.e., with the blade 34 partially extended).
