  • staples or bonding agents are generally used to bind papers. It is not so easy to open the papers bound by such manner. Further, the papers are sometimes subjected to soil and damage due to rust of staples or change in quality of bonding agent. A pair of scissors or a knife is generally used to open a letter. Thus, various kinds of tools are necessary for binding papers or opening a letter and if only one of these tools is not at hand we suffer much inconvenience.
  • a binding device of this invention comprises: a lower member for receiving papers to be bound; an upper member pivotally mounted on the lower member; U-shaped cutter means attached to the upper member; l-shaped knife means attached to the upper member and spaced by a given distance in parallel with the U-shaped cutter means; and cam means pivotably mounted on the U-shaped cutter.
  • a binding and opening device of this invention comprises: a lower member for receiving papers to be bound or a letter to a link mechanism for slidably supporting the upper member on the lower member; a plurality of sets of the U-shaped cutter means, l-shaped knife means, and cam means coupled through the link mechanism to the upper member; upper edge means coupled through the link mechanism to the upper member; and lower edge means attached to the lower member in opposition to the upper edge.
  • the upper edge means engages the lower edge means to open the letter.
  • the respective I-shaped knife means inserts the respective U-shaped portions into the respective I-shaped slots.
  • an object of this invention is to provide a device for binding papers without using a special binding element or bonding agent.
  • Another object of this invention is to provide a binding and opening device wherein papers or a letter can be bound and opened by a single tool.
  • FIG. 11 is an uncovered end view looking from the right of the elevation shown in FIG. 10.
  • FIG. 12 is an uncovered end view looking from the left of the elevation shown in FIG. 10.
  • an upper'member 10 is pivotally attached to a lower member 20 by a pivot pin 30.
  • An aperturedretaining member of keep plate 40 is disposed .between upper member 10 and lower member 20 and attached to upper member 10.
  • a compression spring 50 is disposed between upper member 10 and keep plate 40 while a leaf spring 51 is disposed between keep plate 40 and lower member 20.
  • Upper member 10 is provided with a cutter 60, a knife 70, and a cam 80.
  • cutter 60 and knife 70 are spaced in parallel with each other and fixed to a handle portion 11 of upper member 10.
  • Cam is'disposed between cutter and knife 70.
  • Cam 80 is pivotably mounted on cutter 60 fixed on upper member 10.
  • a biasing leaf spring 81 engages a rear face 82 of cam 80.
  • the cutting edges of cutter 60 and knife 70 have a U-shape and an I-shape, respectively, to cut corresponding spacedly adjacent slots in paper retained by the plate 40 on the receiving surface of the lower member 20, the U-shaped slot defining a bight open toward the l-shaped slot.
  • a rectangular opening 71 is provided in the center of knife 70 (See FIG. 2). Rectangular holes 41 and 42 are provided in keep plate 40 while a rectangular hole 21 is provided in lower member 20 in opposition to associated cutter 60 and knife 70, respectively.
  • FIGS. 1-9 operation of a binding device embodying this invention is explained below.
  • papers 90 to be bound are inserted first between lower member 20 and keep plate 40 and disposed at a given position. Then, by applying a force to handle portion 11 of upper member 10, upper member 10 is moved down to a stop position (See FIG. 5). Finally, by reducing the applied force from the handle, upper member 10 returns to the original position to finish binding of the papers (See FIG. 9).
  • FIGS. 1012 show another embodiment of this invention.
  • a device shown in the drawings can serve to bind papers at a plurality of positions and in addition to open or unseal a letter.
  • a link mechanism 200 is mounted on an upper member or handle 110.
  • a binding mechanism including a cutter 160, a knife 170 and a cam 180 and an upper edge 300 for opening the letter are coupled to link mechanism 200 through a bracket 500.
  • One side of a lower member is provided with a hole 121 for receiving cutter 160, knife and cam 180.
  • a lower shearing edge 400 is mounted on the opposite side of member 120 to confront with an upper shearing edge 300.
  • link mechanism 200 has a conventional structure, it is briefly described below.
  • One end of levers 210, 220, and 230 are pivotably coupled each other by apin 240.
  • the opposite end of lever 210 is provided with an elongated slot 211, which engages a pin 11'1 fixed on upper member 110.
  • the opposite ends of levers 220 and 230 are pivotably mounted on bracket 500 and a frame or housing 600, respectively, the housing being fastened to the lower member 120.
  • bracket 500 is supported by a compression spring 510.
  • the binding mechanism including cutter 160, knife 170 and cam 180 is mounted on one side of bracket 500 while upper edge 300 is mounted on the opposite end of the bracket.
  • plurality sets of cutter 160, knife 170 and cam 180 may be made integrally from a single material, respectively.
  • associated link mechanism 200 When a force is applied to upper member 110 to push it down to the direction of an arrow 112 in FIG. 10, associated link mechanism 200 operates as follows: Lever 210 moves to the direction of an arrow 212, lever 220 to an arrow 222, and lever 230 to an arrow 232, respectively. Consequently, bracket 50% goes down to an arrow 502. Thus, the binding mechanism performs aforementioned operation.
  • Upper edge 300 goes down to an arrow 302 in connection with movement of bracket 500 to engagelower edge 400 fixed on lower member 120. Accordingly, when a letter is inserted into a port 620 and the operations mentioned above are carried out, a specified part of the letter is opened.
  • the binding and opening device in accordance with this invention can bind papers readily without using any conventional staples or a bonding agent and in addition can open letters easily without using a pair of scissors or a knife. Since it is impossible to rebind as even the letter once unbound, this invention is available to keep the privacy of correspondence.

  • cutter means secured to said portion for cutting a first
  • cam means pivotally mounted on said cutter means for holding said flap under said surface during said motion of said portion toward said surface;
  • knife means secured to said portion for cutting a second slot in said received papers spacedly adjacent said first slot during said motion of said portion toward said surface, and for drawing said flap into said second slot during motion of said portion away from said surface;
  • shearing means including 1. a member having a first shearing edge mounted on said portion and spaced from said cutter means, said cam means, and said knife means, said second part of said receiving surface being formed with an opening, and 2. a member having a second shearing edge mounted on said first member contiguously adjacent the opening in said support surface; and
  • manual operating means for moving said portion of said second member toward and away from said surface and for thereby moving said member having a first shearing edge into and out of said opening in shearing cooperation with the member having said second shearing edge.
  • cam means include a cam member, said part of the cam means including a prong on said cam member, and biasing means biasing said cam member toward a position relative to said cutter means in which said prong is directed toward said aperture when said portion is remote from said surface, the device further comprising abutment means on said first member engaging said cam member and thereby pivoting said cam member when said prong moves through said aperture to direct said prong toward said second slot.
  • said knife means include a knife member carrying said cutting edge of said knife means and formed with an opening, said opening passing through said surface during said motion of said portion toward said surface, and said prong entering said opening when said cam member is pivoted by said abutment means.
