Definitions

  • the present invention is directed to a paper guide for a manually operated hole punch used to punch one or more holes in sheet media such as paper.
  • manually operated hole punches include U.S. Patent No. 3,921,487 (Otsuka, et al), U.S. Patent No. 4,077,288 (Holland), and U.S. Patent No. 6,688,199 (Godston, et al.).
  • a punch pin that cuts through the paper stack is slidably held in a rigid frame, which receives the paper stack.
  • the assembly of the punch pin and the rigid frame is known as the punch element.
  • the punch pin is driven through the paper stack to cut a through-hole.
  • the paper stack fits in a slot that serves as the holding area for the punching operation.
  • the slot is usually oriented so that it opens horizontally. With the paper stack residing in the slot, the punch pin with its sharp leading edge cuts through the stack and expels the cut, disk- shaped chips on the opposite side of the stack.
  • the energy to drive the pin in its punching stroke originates from an actuation lever that is linked to the punch pin to advance it through the slot and paper stack.
  • the lever is linked to a handle or it may be directly actuated by the user applying force to it or the handle.
  • An optional return spring engaging the punch pin, lever, or handle is biased so that it assists in the withdrawal stroke of the punch pin out of the punched hole.
  • the present invention in a preferred embodiment is directed to a punch device for cutting holes in stacked sheet media.
  • the punch has a frame having a generally vertically-oriented slot for receiving the sheet media therein, a punch element extending a punch pin perpendicularly through the slot, a handle driving the punch element, at least one extension arm having a distal end extending laterally from the frame and a proximal end remaining inside the frame, wherein the extension arm includes markings thereon, an edge guide having a smooth inner face disposed at the distal end of the extension arm, wherein the edge guide includes an inward extending page lifter, and an opening in the frame forming a window such that the markings on the extension arm are visible through the window.
  • the window is situated above the slot so that it is not covered by the paper stack loaded into the slot and is constantly visible to the user.
  • the punch device in the preferred embodiment includes an extension arm on each side of the frame extending laterally therefrom, and each extension arm includes an edge guide at a distal end thereof.
  • the edge guide preferably has a longitudinal shape and is tilted in parallel with the slot.
  • the punch device has a window that is optionally covered by a transparent material, and the page lifter includes a curved planar shape.
  • the page lifter may further define a plane that is not co-planar with a plane defined by the slot.
  • the punch device is designed so that the two extension arms are ratcheted to each other via a common pinion gear disposed to the interior of the frame.
  • the punch device improves the hole punching operation in sheet media by quickly enabling the correct page size to be selected by using the window and marked indicia, overcoming any natural curl in the sheet media to ensure precise and clean hole cuts, and quickly aligning the stack and sheet media by employing one or more guides.
  • FIG. l(a) is a side elevational view of a preferred embodiment hole punch with a single edge guide.
  • FIG. l(b) is a front elevational view of the hole punch from FIG. 1.
  • FIG. l(c) is a cross-sectional view of the hole punch taken along line B-B of FIG. l(b).
  • FIG. l(d) is a cut-away perspective view of the hole punch where one side has been removed to expose the interior.
  • FIG. 2 is a perspective view of another hole punch embodiment with two edge guides retracted or closed.
  • FIG. 3 is a perspective view of the hole punch showing the edge guides extended or open.
  • FIG. 4 is a top plan view.
  • FIG. 5 is back perspective view. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • the present invention is directed to a paper guide for a hole punch, shown in
  • FIG. l(a) is a side elevational view of a preferred embodiment hole punch 5.
  • the hole punch 5 is further shown in a front elevational view in FIG. l(b), in a cross-sectional view in FIG. l(c), and in a cut away view in FIG. l(d).
  • This embodiment includes a housing body 20 covering the internal punch element mechanicals, one edge guide 32 for helping arrange the paper stack to be punched, and a nearly-vertically oriented slot 14 for receiving the paper stack.
  • the preferred embodiment hole punch includes one or more punch elements with respective punch pins 7.
  • an actuation handle or lever 12 is linked to the punch pin 7 to drive it through a stack of papers or like sheet media (not shown) residing in the slot 14.
  • a reset spring 9 assists in the withdrawal of the punch pin 7 after the punch stroke to return the mechanicals to the start position.
  • the structure and operation of the punch element, actuation handle, etc. are disclosed in, for example, U.S. application no. 11/336,300, titled "HOLE PUNCH" by Joel S. Marks, filed January 20, 2006, whose entire contents are incorporated by reference.
  • the manually operated hole punches 5, 10 have a housing body 20 with a near- vertical slot 14 for accepting the sheet media or paper stack therein.
  • the slot 14 includes an opening 22 leading to the closed bottom 24 of the slot 14.
  • the almost vertical orientation of the slot 14 ensures that when the paper stack is inserted therein it remains situated almost vertically. This slot orientation minimizes table top surface area generally occupied and shrinks the footprint for the hole punches 5, 10.
  • the almost vertical orientation of the slot 14 exploits the pull of gravity on the paper stack to make sure the leading edge is fully inserted into the slot, and to work in concert with the edge guide described in further detail below.
  • First and second guide surfaces 26, 28 adjacent the slot opening 22 help the paper or sheet media feed into the slot 14.
  • the guide surfaces 26, 28 are a curved surfaces arranged in a confluence such that the gap therebetween narrows down to the gap defined by the slot height.
  • each paper edge guide 32 has a large flat surface that faces the edge of the paper stack and is generally oriented in a direction parallel to the slot 14. So as seen in FIGS. 2-3, the edge guides 30, 32 are oriented slightly off the vertical as is the slot 14.
  • At least one edge guide 30, 32 projects from the side of the housing body 20 via an extension arm 34, 36.
  • the extension arm 34, 36 slides into and out of the body 20 to adjust the distance between the opposing edge guides 30, 32.
  • This in turn accommodates the hole punch 10 to accept different sized papers such as standard letter 8.5" x 11", A4, or 8.5" x 14" legal size, etc., or different orientation of papers.
  • an 8.5" x 11" paper can thus be placed inside the slot 14 with the narrow 8.5- inch side inside the slot or the 11 -inch side inside the slot, and the edge guides 30, 32 can be slidably adjusted to match those sizes.
  • the two extension arms are ratcheted to a toothed, rotating pinion inside the housing (not shown) so the two extension arms can slide simultaneously in opposite directions.
  • the edge guides 30, 32 once adjusted to the correct stack width help align the loose papers in the stack.
  • Each edge guide 30, 32 further includes optional lifter tabs 38, 40 that have a slight curvature.
  • the lifter tabs 38, 40 counteracts gravity and the natural bowing in the paper or sheet media stack by gently lifting the unsupported outer edges of the paper stack. That is, the flat part of the paper stack at the outer periphery is supported by the lifter tabs 38, 40.
  • the optional slight curvature of the lifter tabs 38, 40 places a slight reverse bend to the bowed papers. To visualize this, in the top plan view of FIG.
  • the paper stack would normally bow to form a convex curve (i.e., a frown) across the slot 14, while lifter tabs 38, 40 would diminish the convexity of the sheet stack and induce a concave bend (i.e., a smile) across the width of the slot 14.
  • the ideal end result is a sheet stack that rests straight across the width of the slot 14 for improved alignment prior to the hole punching step.
  • Each extension arm 34, 36 optionally includes markings or indicia 42 that provide the numeric dimensions of the paper or sheet media (e.g., 8.5", 11", 14", 210 mm, 297 mm, etc.) or alphabetic designations of the paper size (e.g., LTR, LGL, A4, etc.).
  • the indicia 42 may be a sticker, inked, etched, cut, stamped, embossed into the arm, a raised contour on the arm, or the like.
  • the arm 34, 36 may be metal, plastic, or the like so creation of the indica 42 on the arm 34, 36 is achieved through processes known in the art.
  • a window 44 is provided in the guide surface 26.
  • the window 44 may be covered by a transparent sheet of plastic to keep dust or paper chips from accidentally falling into the window and collecting inside.
  • the hole punch 10 includes multiple punch pins/punch elements, and the spacings between them are fixed.
  • the distance between the punch pins may be adjustable by the user. Therefore, the holes to be cut may be set at pre-marked spacings.
  • the punch elements slide on a bar (not shown) with the indicia described above and are screwed down or locked down to the bar at preset detents or notches. The indicia on the bar to adjust the punch element spacings may be likewise made visible through the window.
  • the punch elements are linked to the edge guides so moving the edge guides moves the respective punch elements.
  • the indicia seen through the windows informs the user of the hole spacing as well as the paper size.
  • the windows 44 are located above the slot 14 so that they are visible to the user even though the slot 14 is occupied by a stack of papers.
  • the slight angle of the slot 14 and the weight of the paper stack curl the stack forward toward the user and downward toward the desktop, and away from covering the windows 44. Since the windows 44 and indica 42 inside are constantly visible to the user, he or she can rest assured that the paper - -
