Definitions

  • This invention relates to ring binders to hold paper and the like for loose-leaf binders, files, folders and the like.
  • GB-A-2 209 500 discloses a ring binder mechanism for a loose-leaf binder with ring elements secured to the carrier rails within a cover rail in which the cover rail is provided with a longitudinal indentation which provides increased strength and rigidity to the mechanism. It is suggested that there could be two or more indentations. In particular, there could be two parallel indentations located symmetrically on either side of the cover rail, and the shape and position of each indentation should be chosen to give the desired stiffening effect.
  • a plate for forming a housing member for supporting a pivotable lower structure in a ring binder wherein the plate is provided with at least one rib positioned along each lateral side thereof, and wherein when the plate is formed into the housing member, the ribs are below the part where the housing member supports the pivotable lower structure.
  • the ribs are provided along the substantial length of each lateral side of the plate.
  • Such ribs cause the sides of the housing member to be exactly normal to the rest of the housing member, and accordingly carrier rails inserted into the housing member will not tend to drop out.
  • At least one indentation is provided adjacent each lateral side of the plate.
  • the indentations project from the plate in the opposite direction to that of the ribs.
  • a ring binder 10 for a loose-leaf binder comprising a base member 12, three ring members 14 spaced along the base member (only one of which ring members is shown in Figure 1), and an opening and closing mechanism 20 at each end of the base member (again only one of which mechanism is shown in Figure 1).
  • the base member 12 comprises a housing member in the form of an upper rigid structure 24 which is curved in cross-section and which supports between its two overlapping sides 26 a pivotable lower structure 30 comprising two carrier rails 32 pivotable to each other along the longitudinal axis of the binder 10.
  • the ring members 14 are mounted on the pivotable lower structure 30 and in particular, one of the ring components (ie component 14a) of each ring member is mounted on the carrier rail 32 while the other ring component (not shown) of each ring member is mounted on the other carrier rail (also not shown).
  • Fastening means 34 are also provided on the upper structure 24 in order to secure the ring binder 10 to a paper folder or the like.
  • the two carrier rails 32 are movable (ie pivoted) relative to each other between a lower position and an upper position due to the action of the opening and closing mechanism 20 on each end of the carrier rails.
  • the opening and closing mechanism 20 is pivotably supported on each end of the upper rigid structure 24 and is in engagement with each end of the pivotable lower structure 30 in order to position the opening and closing mechanism 20 between the upper and lower structures.
  • the housing member 24 of the ring binder 10 is formed by pressing a pre-shaped metal plate using a pair of metal dies.
  • a prior art pre-formed metal plate 36 is shown which is flat and elongated, and provided firstly with six slots 37 through which the ring members 14 will pass when the ring binder is assembled, and secondly with an indentation 41 at each end in which the opening mechanism 20 will be positioned when the ring binder is closed.
  • the plate 36 is also shown having two holes 39 through which the fastening means 34 will pass when the ring binder is positioned on a folder or the like, these holes 39 being only punched when the housing is being formed.
  • Each side of the plate 36 is pressed into shape by a pair of metal dies whereby it is bent at each side substantially 90° to the rest of the plate.
  • the metal itself however, has a rebound elasticity, and therefore, the folded sides tend to deviate outwardly by a small angle from the abovementioned 90°.
  • the metal plate 36 when the metal plate 36 is forced to form a housing member, its inner and outer surfaces will be under a compression force and a tensile force respectively. Such will relieve and rebound outwardly when the dies are parted, and a small deviation angle between the sides and the normal is obtained.
  • different materials used and thicknesses have a different rebound elasticity.
  • the plate 40 is also provided with four indentations 42 which project from the plate in the opposite direction of the ribs 38 (ie inwardly of the plate), and these indentations 42 form projections which in co-operation with sides normal to the rest of the housing member) totally prevent the carrier rails 32 when inserted into the housing member from dropping out of the housing member during assembly.
