Definitions

  • This invention relates to a loose leaf hinder, or file, for papers and the like, consisting of a base plate with rigid filing pins and pivotally mounted arched closing members connected by a crank-type olfset pivoting memher under tension from a leaf spring, and of an opening and closing device actuated by pressure applied in the direction of the base plate on the offset section of the pivoting member.
  • the invention consists essentially in the provision of an opening and shutting device in the form of a singlearm lever with a ratchet and pawl system, which has a cam disk with equidistant cams that impart movement to the offset portion of the pivoting member in such manner that with a predetermined lever movement the cam disk is advanced one-half of the cam interval, permitting the ofiset portion of the pivoting member to move through a distance equal to the vertical deviation of the lowermost cam when advanced.
  • the construction of such loose leaf binder may conveniently be carried out in a variety of Ways.
  • the lever with ratchet and pawl and the cam disk are mounted, parallel to the pivoting axis of the arched closing members and with their side faces approximately perpendicular to the base plate, on a support which for this purpose has a .pin in the transverse central plane perpendicular to the base plate for the revolving seating of the cam disk, and off-center from said pin a pivot pin which serves as fulcrum for the lever.
  • the cam disk may be conveniently constructed as a ratchet wheel, whereby its circumference is furnished with double as many ratchet teeth as there are cams, said cams being located on the cam disk face towards the olfset section of the pivoting member.
  • the offset section of the pivoting member is provided with a notch-like shoulder, symmetrically positioned in relation to the transverse central plane perpendicular to the base plate, said shoulder being so formed that in order to close the arched members the following cam, by depressing the olfset section, engages the shoulder, while to open the arched members the shoulder is introduced between the following and preceding cams, both of which act as stops for the offset section when the arched members are open.
  • Figs. 1 and 2 are respectively a side elevation and a front elevation of a loose leaf binder mechanism in accordance with the invention in the closed position, th arched members in Fig. 1 being broken off,
  • Figs. 3 and 4 are respectively a side elevation and a front elevation of the same mechanism in the open position
  • Fig. 5 is a front elevation of the ratchet wheel, by itself, with a modified form of pawl, and
  • Fig. 6 is a side elevation of the end of the pressure lever.
  • the loose leaf binder consists of a base plate 1 on which are positioned two normally spaced filing pins 2 as well as two arched members 4 spaced at the same distance as the filing pins 2 and pivotally mounted in the clips 3 of the base plate.
  • the arched members 4 are connected with each other by a common pivoting member 5. Between the clips 3, this pivoting member 5 has an inwardly offset, U-shaped pressure how 6, which is preferably furnished in the middle with an upward-projecting shoulder 7.
  • the shoulder 7 has a notch-shaped depression 8 in the center. Pressing against the underside of the pressure how 6 is a leaf spring, the form illustrated having three sections.
  • the two outer spring tongues 9 serve to press up the pressure bow 6, while the middle tongue 10 is extended to fulfil a purpose to be explained hereinafter.
  • an upright support 11 Positioned on the base plate 1 at about the middle of the loose leaf binder mechanism is an upright support 11, preferably consisting of a strip of metal stamped out of the base plate 1 and bent upwards.
  • a ratchet wheel 13 On the support 11 a ratchet wheel 13 is seated so that it will rotate round a pin 12. Around its circumference this ratchet wheel has, for example, six teeth 14.
  • rotating rollers 16 are seated on the cam pins 15.
  • cam pins and corresponding numbers of ratchet wheel teeth may be provided, whereby the number of teeth should always be double or a multiple of the number of cam pins.
  • the rollers 16 of the cam pins 15 move in one plane over the shoulder 7 of the pressure how 6.
  • the rollers 16, which work in conjunction with the pressure how 6, are mounted on the cam pins 15 with a little axial play so that they can follow the pivoting movement of the pressure bow 6.
  • an actuating lever or pressure lever 18 is pivotally mounted on a pivot pin 17 eecentrically located in relation to the ratchet wheel axis 12, the free end of which lever protrudes from the loose leaf binder mechanism to the front or to the rear and which bears a key button 19.
  • an axis 20 is a pawl 21, the tooth 22 of which engages the teeth 14 of the ratchet wheel 13.
  • a spring 23 mounted on the lever 18 exerts downward pressure on the Y pawl 21, pressing the latter elastically on to the teeth of
  • the form of the articulated end of the lever 18 is illustrated in Fig. 6.
  • any type of spring may be provided to return the lever 18 to its raised, rest position.
  • the middle tongue of the leaf spripg 9, 10 may be .used for this purpose with advantage, such manner that the extended end lies againstalower, protruding lobe 25 .of thelever 18 (Fig. 6).
  • V i A special .pawl spring 23 may be dispensed with if the pawl is so positioned and formed that its own weight causes it to engage the teeth of the ratchet wheel 13. In this case it is preferable to furnish the pawl 21 with an opposed lever arm 26 as shown in Fig. 5.
  • the lever .arm 26 can be provided with a safety tooth 27 at this P int-
  • the arched members 4 can not open completely outwards because the two lower cam pins 15 on both sides of the shoulder 7 are still resting on the pressure bow 6 and in this way act as upper limiting stops.
  • An opening and closing device for a loose/leaf hinder or file for papers and the like in which the binder includes a 'base plate and a crank-type offset member pivotally mounted on the base plate, comprising a single-armed lever, a pawl having a tooth and ratchet wheel connected to be operated by the lever, a plurality of equidistant cams mounted on the ratchet wheel to act on the offset section of the member so that with a predetermined lever movement the ratchet wheel is advanced one half of a cam interval, and a spring mounted on the base plate and hearing against the offset section of the member the ratchet wheel being mounted in a plane at right angles to the base plate and the offset section of the member being moved through a distance equal to the stroke of the corresponding cam nearest the base plate when advanced.
  • An opening and closing device in which the lever is pivoted on a support eccentrically arranged in relation to the ratchet and is provided with a slot by which the pivotal movement of the lever can be limited.
  • An opening and closing device in which said leaf spring is also provided with a spring tongue exerting pressure .on the lever opposite to the pressure of the cam thrust.
  • An opening and closing device in which the pawl is mounted on the lever and engages teeth on the ratchet, said pawl being curved in the segment of a circle and is so pivoted that the pawl rests on the teeth of the ratchet and exerts a pulling force on the teeth when the lever is depressed.
  • An opening and closing device m which the pawl is provided with a lever arm extending beyond the pivotal point on the lever, and on which lever arm there is provided a second tooth opposite to the tooth of the pawl.
  • cams are in the form of three rollers mounted on the ratchet wheel and the offset member is provided with a shoulder with a depression therein so that when any two rollers are in contact with the shoulder of the offset member the binder will be closed and when the ratchet is rotated so that one roller is in contact in .the depression of the shoulder the binder will be open.
  • opening and closing device in which the cams are in the form of three rollers mounted on the ratchet wheel and the offset member is provided with a shoulder with a depression therein so that when any two rollers are in contact with the shoulder of the offset member the binder will be closed and when the ratchet is rotated so that one roller is in contact in the depression of the shoulder the binder will be open, and in which the ratchet wheel has six teeth thereon with the lever rotating the ratchet wheel one sixth of a revolution with each downward movement .of the lever.
