Other types of loose leaf binders, however, are constructed with one or both halves of the binder loops mounted for transverse sliding movement.
  • US. Pat. No. 788,023 discloses a binder in which the segments which make up the binder loops are mounted on two portions, a stationary member and one which is slidably movable with respect to the other in a transverse direction.
  • the slidable member is provided with grooves in an upper surface thereof and a controlling bar having pairs of fingers received in the grooves of the upper surface of the slide member and additional fingers received in a groove in the stationary member inparts transverse sliding movement to the slidable member through a camming action.
  • a binder fixture consisting mainly of three slidably interfitting parts which can be molded using modern injection molding techniques particularly adapted to modern synthetic resinous materials such as polypropelene and a combination of acrylonetrele, butadiene and styrene known as ABS.
  • modern injection molding techniques particularly adapted to modern synthetic resinous materials
  • ABS acrylonetrele, butadiene and styrene
  • the binder fixture includes a stationary base plate having a series of substantially T-shaped rails extending across an upper surface thereof, a channel formed in a lower surface thereof and a pair of slots extending through the base plate at the channel.
  • a longitudinally extending cam bar is slidably received in the channel in the lower surface of the base plate and has a pair of pins projecting upwardly through the slots extending through the base plate.
  • a slide plate has a series of T-shaped slots formed in its lower surface which are complementary to and in engagement with the T-shaped rails formed on the upper surface of the base plate, thereby permitting transverse sliding movement of the slide plate on the base plate.
  • the lower surface of the slide plate is also provided with cam grooves which receive the pins projecting upwardly through the slots in the base plate.
  • the cam grooves in the slide plate have a first portion which is angularly disposed with respect to the axes of the slide plate and a second portion, which serves as a lock portion extending parallel to the longitudinal axis of the slide plate.
  • the base plate and the slide plate each have upwardly and inwardly projecting binder loop segments which cooperate when the slide plate is in the closed position to define binder loops.
  • Sliding action of the slide plate on the base plate is obtained by sliding the cam bar in the channel in the lower surface of the base plate, causing the pins projecting upwardly through the slots in the base plate and received in the cam grooves in the lower surface of the slide plate to move the slide plate between open and closed positions. Once the slide plate has moved to the closed position continued movement of the cam bar will cause the pins thereon to enter that portion of the grooves in the slide plate which extend longitudinally thereof, locking the slide plate in the closed position.
  • FIG. 1 is a perspective view of the binder fixture of the present invention attached to a binder cover with the fastener in its closed position;
  • FIG. 2 is a view similar to FIG. 1 but showing the binder fixture in the open position
  • FIG. 3 is a view taken on line 33 of FIG. 1;
  • FIG. 4 is a view taken on line 4-4 of FIG. 2'
  • FIG. 5 is an exploded perspective view of the present invention.
  • FIG. 6 is a view taken on line 66 of FIG. 1.
  • the binder fixture 10 of the present invention consists of only three parts, a stationary base plate 12, a slide plate 14 and a cam bar 16.
  • the base plate 12 is provided with an elongated channel 18 formed in the lower surface 19 of the base plate and extending from one end 20 thereof to a point short of the opposite end 22.
  • a pair of longitudinally spaced slots 24 are formed through the base plate at the channel 18.
  • a plurality of curved binder loop segments 26, three being shown for purposes of illustration, extend upwardly and inwardly from the top of the base plate 12.
  • the slide plate 14 has a pair of cam grooves 28 formed in the lower surface 30 thereof and each cam groove 28 includes an angularly disposed camming portion 32 and a longitudinally extending locking portion 34. It will also be noted that the slide plate 14 is provided with a plurality of curved binder loop segments 36 extending upwardly and inwardly thereof with each binder loop segment-36 being provided with an inwardly projecting socket portion 38 adapted to engage a complementary portion 39 on the binder loop segment 26, as seen, for example, in FIG. 2.
  • the cam bar 16 is provided with a handle 40 adjacent one end thereof which is adapted to project outwardly of the base member, as best seen in FIGS. 1 and 2 of the drawings. Additionally, and with reference to FIG.
  • a pair of cam fol- The assembly of the base and slide plates and cam bar 16 is attached to a binder cover 46 by means of rivets or the like 48, and in this regard, it will be noted that the lower surface 30 of the slide plate 14 is provided with notches 50 adjacent each end thereof which accommodate the heads of the rivets projecting above the upper surface 44 of the base plate 12. It will also be noted that attaching the binder fixture to the cover 46 confines the cam bar 16 within the channel 18, while permitting sliding movement of the cam bar longitudinally thereof.
  • the upper surface 44 of the base plate 12 is provided with substantially T-shaped rails 52 slidably received in complementary shaped T-shaped slots 54 formed in the lower surface of the slide plate 14, with the slots and rails serving as guide means during slidable movement of the plate 14.
  • cam bar 16 is moved upwardly from the position shown in FIG. 2 to that shown in FIG. 1, with initial upward movement of cam bar 16 causing the slide bar 14 to move to a closed position and additional movement of the cam bar 16 causing the pins 42 to engage portions 34 of the grooves 28, locking the slide and base plates together with the complementary socket portions 38 and 39 on the distal ends of the binder segments in engagement with each other.
  • the present invention provides a binder fixture which operates with a positive opening, closing and locking action and which may be readily fabricated from synthetic resinous materials such as polypropelene or ABS using modern injection molding techniques.
  • a binder fixture comprising:
  • cam follower means projecting upwardly from an upper surface of said cam bar through elongated slots in said base plate above said upper surface thereof, means for sliding said cam bar in said channel,
  • cam groove means formed in said lower surface of said slide plate extending angularly with respect to the longitudinal axis thereof and receiving said cam follower means
  • interengaging guide means formed on opposing upper and lower surfaces of said base and slide plates and guiding sliding movement of said slide plate transversely of said base plate
  • said plates are formed of a synthetic resinous material.
  • said synthetic resinous material is selected from a group consisting'of polypropelene and ABS.
  • said synthetic resinous material is ABS.
  • interengaging guide means comprises:
  • said rails are of substantially T-shaped configuration
  • said slots formed in said lower surface of said slide plate are of complementary T-shaped cross sectional configuration.
  • cam groove means comprises:
  • a binder fixture comprising:
  • an elongated cam bar having a thickness approximately equal to the depth of said channel slidably received in said channel with one end of said bar projecting outwardly of said channel at said one end of said base plate
  • fastening means attaching said binder cover to said lower surface of said base plate and confining said cam bar in said channel formed in said lower surface of said base plate
  • said plates being formed of ABS
  • m. means defining substantially T-shaped slots formed in said lower surface of said slide plate extending transversely thereof and slidably receiving said substantially T-shaped rails on said upper surface of said base plate,
  • each of said cam grooves including a first portion extending angularly with respect to the longitudinal axes of said base and slide plates and a second portion extending substantially parallel to the longitudinal axes of said base and slide plates,
  • g. means defining curved binder loop segments projecting upwardly and inwardly from said upper surface of said slide plate and forming substantially semi-circular, closed binder loops with said segments on said base plate when said slide plate is in a closed position thereof with respect to said base plate, and
