Definitions

  • the present invention relates to hole punches.
  • Embodiments of the present invention may relate more particularly to desk-top hole punches for punching holes through paper.
  • Hole punches are employed to punch holes through sheet paper to allow a user to place the sheet paper in a ring binder.
  • the hole punch includes one or more punch heads acted upon by a lever, whereby actuation of the lever causes the punch heads to pierce through the paper and create a hole.
  • the effort necessary to punch the holes also increases.
  • Hole punches exist where additional punching force can be applied through the provision of a longer lever. This solution, however, typically results in a relatively large hole punch, increasing the overall footprint or envelope of the hole punch, and rendering them less suitable for use in smaller work areas.
  • DE 925 110 C discloses a punch having cooperating levers arranged to be rotatably mounted at opposite ends of a punch housing and to be interlocked in a central region of the punch, such that the levers are articulated together to drive respective punching pins. To this end, a pin on one lever slides along a guide slot in the other lever, which slot is L-shaped.
  • DE 10051625 A1 which represents the closest prior art discloses hole punches in which a pair of levers are rotationally mounted inside a housing.
  • An upper housing covers and encloses the levers. By depressing the upper housing, the levers are rotated to drive respective punching pins.
  • a bar connects the punching pins, and is driven down by a camming action of the levers at each end. Bearing surfaces of the levers engage at their other ends with the inside of the housing cover.
  • a hole punch comprising: a base having a longitudinal axis, the base having a first end and a second end; a first lever having a first end pivotally connected to the first end of the base, the first lever constructed and arranged to pivot about an axis that is substantially perpendicular to the longitudinal axis; a second lever having a first end pivotally connected to the second end of the base and a second free end, the second lever constructed and arranged to pivot about an axis that is substantially perpendicular to the longitudinal axis, the second lever cooperating with the first lever such that actuation of the free end of the second lever causes the first lever to move, the second lever having a curved engagement surface which interacts with the first lever; a third lever having a first end operatively coupled to the first lever and a second end operatively coupled to the second lever; and at least one punch head mounted to the base, the punch head having a punch, with the third lever adapted to engage the punch and move the punch from
  • Embodiments of the invention are able to provide improved hole punches, including hole punches that balance the need for increased leverage yet take up minimal amount of space.
  • embodiments of the present invention are realized as hole punches constructed in a manner whereby a balance is struck between the overall size (whether in use or in a storage mode) of the hole punch and the actuation force required to punch the holes.
  • the efficiency with which holes can be punched through the sheet or sheets of paper, while maintaining a sleek and low profile hole punch is provided.
  • the hole punch includes a base having a longitudinal axis, with the base having first and second ends, and a lever arrangement joined to the base.
  • the pivot axes of the levers are substantially perpendicular to the longitudinal axis.
  • One of the levers overlies and engages the other and may include a free-end such that applying a force on the free-end causes the lever to pivot in one direction which then presses on the other lever causing it to pivot in an opposite direction.
  • the two levers are coupled to a third lever or bar element which then presses on punch heads.
  • the hole punch includes a lock to hold the lever arrangement in a closed or partially closed position, thereby reducing the envelope of the hole punch.
  • the lock is disposed on one lever whereby a hook slidingly engages a pocket on the other lever.
  • Other suitable locking arrangements may be employed, as the present invention is not limited in this respect.
  • the hole punch includes a waste drawer slidingly received relative to the base and positionable beneath the punch head to capture a resulting chad after paper is punched.
  • the hole punch includes a slide rule to aid with alignment of a sheet of paper relative to the punch heads.
  • the slide rule has a first portion slidingly engaged in the base and a second, upstanding portion.
  • the upstanding portion may include a cover or otherwise be overmolded with a plastic material.
  • the punch heads may include a generously radiused entry.
  • the sheet-entry surface has a lead-in radius of approximately 11 mm. However, other suitable lead-in radii may be employed, as the present invention is not limited in this respect.
  • the hole punch 10 includes a base 12 having a longitudinal axis 13 running lengthwise relative to the base.
  • the base also includes upstanding end portions 14, 16, a plurality of punch heads 18 and a lever system 20 to activate the punch heads.
  • the lever system 20 includes a first lever arm 22 pivotally joined to the upstanding end portion 14, and a second pivotal arm 24 pivotally joined to the opposite upstanding portion 16 of the base.
  • Each lever arm is pivotally connected via hinges 27, 29, to the end portions in a manner such that their respective pivot axes 28, 30 are substantially perpendicular to the longitudinal axis 13 of the base 12.
  • Levers 24 and 22 are arranged in a manner such that lever 24 extends over lever 22.
  • Lever 24 includes a second free end 25 extending beyond the engagement area (located generally at 23) of levers 22, 24 that can be handled by a user to actuate the hole punch.
  • lever 24 upon pressing down on the palm area 26 of the lever 24 in a counterclockwise direction along arrow A, as shown in FIG. Ia, lever 24 rotates about pivot axis 28 and subsequently engages lever 22, causing it to rotate clockwise in FIG. Ia about pivot 30.
  • the levers rotate from the pre-actuation or rest position of FIG. Ia to the closed or punch position shown in FIGs. 1 and 2 .
  • lever system 20 also includes a third lever 32, with its ends respectively engaging levers 22, 24, and also engaging the punch heads 18.
  • the engagement between levers 22, 24 and lever 32 is such that downward rotation of the levers 22, 24 causes downward motion of lever 32 onto the punch heads.
  • actuation of the punch heads via the lever 32 causes punches within the punch heads to pierce through one or more sheets of paper (not shown), hi this regard, the punch moves from a rest position to a deployed position upon actuation of the free end of the second lever.
  • the third lever 32 is coupled to each of the levers 22, 24 at end flanges 34, 36, respectively.
  • each flange engages the lever 32 via a pin connection 38, 40.
  • the present invention is not limited in this regard, as other suitable connection arrangements may be employed.
  • the receiving holes 42 of the lever arm 32 are elongated so as to form a slot.
  • Each flange 34, 36 includes a hole 34a, 36a to receive a pin 38, 40. It should be appreciated that the present invention is not limited in this regard, as other suitable connections may be employed. For example, rather than a pin 38, 40, the flange may include a detent to snap into the hole in the bar 32.
  • lever 32 includes a U-shaped channel member, hi the embodiment shown, lever 32 may be formed as a single piece of metal stamped in the shape shown; however, the present invention is not limited in this regard, as other suitable forming techniques may be employed, such as utilizing two or three separate pieces that are subsequently joined together via various joining techniques, such as welding.
  • the lever is formed in a manner where the beam is taller in the central area than at the ends. This arrangement may reduce the amount of material and weight of the lever, while maintaining its structural integrity.
  • the present invention is not limited in this respect, as the beam height may be uniform along its length.
  • the lever 32 includes a thicker bottom section 33, which may be integral with the material prior to forming or attached subsequently. In this manner, the thicker section may be better able to withstand the opposing force from the punch heads during use.
  • lever 32 need not be formed in a U-shaped manner, as other suitable arrangements for rending the lever more rigid may be employed. Indeed, the lever may be formed as a solid piece.
  • the end of the lever 22 contacts the underside of lever 24 around about the mid-section 23 of lever 24. Contrasting FIGs. 1 and Ia, as lever 24 moves counterclockwise from the position shown in FIG. Ia to the position shown in FIG. 1 , the end of the lever 22 slides along the under surface of lever 24.
  • the underside surface of lever 24 includes a curved section 50, which interacts with the end of lever 22 (not shown in FIG. 6 for clarity).
  • a controlled motion of the lever 22 to the closed position can be accomplished in that the radius of curvature of the curved surface 50 corresponds to the motion of the end of the lever 22 as it rotates about hinge 29.
  • curved section 50 is shown integral with lever 24, the present invention is not limited in this regard as the curved surface may be formed as a separate member that is subsequently attached to the underside of lever 24.
  • the end of the lever includes a roller bearing 52, as best shown in FIGs. 2 and 3 (Lever 24 has been removed in FIG. 3 for clarity).
  • the roller bearing is free to rotate relative to the lever 22 such that a smooth and relatively frictionless motion occurs between the movement of lever 24 over lever 22.
  • the roller bearing 52 may be formed separate from the lever 22 and subsequently mounted thereto. It should be appreciated that the present invention is not limited in this regard and that the roller bearing need not be employed.
  • the end of the lever 22 may be coated with a material with a reduced coefficient of friction to allow sliding motion of the levers 24, 22 relative to each other as the hole punch is actuated.
  • a slide rule may be employed.
  • the slide rule 60 fits within the base 12 and may be configured so as to slide along the base and be held in a desired position.
  • the slide rule may be held in such a position through the use of a detent mechanism or -merely-by-frictional engagement between the slide rule and the base.
  • the slide rule may be infinitely adjustable along its length or may have preset positions at which it locks so that a user can simply move the slide rule to a desired corresponding position.
  • Such a preset may be in the form of notches formed in the slide rule with a corresponding detent in the base to hold it in place.
  • the slide rule itself may include demarcations (whether in inches or portions thereof, or centimeters or portions thereof) to indicate a corresponding dimensional position of the slide rule relative to the punch heads.
  • the base includes a window 62 for viewing the slide rule.
  • the base window 62 also includes a pointer 64 (in this illustrative embodiment shown in the shape of an arrow) that can be used to point to a section or demarcation line on the slide rule to allow a user to determine where the slide rule should be positioned.
  • the slide rule includes up-turned end 66, as shown, to act as a buttress for the paper.
  • This up-turned end 66 may include a cover 68.
  • the slide rule is formed of metal whereas the cover is formed of a thermoplastic material.
  • the cover may be held in place with an adhesive or other suitable connection technique, as the present invention is not limited in this regard.
