Definitions

  • the present invention relates to a closure for a file mechanism according to the preamble of claim 1.
  • a folder mechanism with the features listed in the preamble of claim 1 is the subject of the Swiss patent application 501/90 and the European patent application 91810081.9.
  • the subject of these patent applications is a locking mechanism for file folders, with at least two brackets, each of which is divided into a left and a right bracket part in their upper regions and which can be opened by pivoting the bracket parts on one or both sides.
  • the bracket parts on one side are each attached to a carrier plate, and the carrier plates are pivotally connected to a base plate in the region of their outer edge.
  • a lever is pivotally attached at one end, which lever is intended to press the areas of the support plates facing the center of the base plate from above against the force of elastic means in the direction of the base plate.
  • the base plate is connected to means for blocking the movement of the lever.
  • the pivotable lever forming the actuating member of this mechanism is an elongated body, the cross-sectional shape of which is a U-profile which is open at the bottom and which covers a longitudinal rail which is present in the center on the base plate of the mechanism and which is at the top.
  • a bar made of an elastic plastic is provided as a means for blocking the movement of the lever, which is embedded in the longitudinal rail of the mechanism. To open mechanically, this bolt must be pulled backwards at its end protruding upwards from a recess in the pivotable lever.
  • the pivotable lever is designed as an upwardly open bracket.
  • This version has the advantage over the former that the lever is still lower overall and consequently the mechanism can be implemented in the version with a high and with a low bracket on the basis of the same basic structure.
  • a latch is provided as a means for blocking the movement of the lever, which is inserted in a recess provided in the end face of the longitudinal rail of the mechanism. To open the mechanics, this lever must be pushed forward.
  • the last-mentioned latch has the disadvantage that one-handed operation to open the folder mechanism is not possible, because the user must hold the folder equipped with such mechanism with the other hand to open the mechanism so that it can be pulled out or pushed in the bar does not slide away. To ensure one-handed operation of the bolt, it should be possible to operate it, for example, by pressure from above.
  • the two latches mentioned have the disadvantage that the user who is not familiar with this mechanism does not always see at first glance how the latch is to be opened. The use of a new type of mechanism, which has not yet been introduced into a wide range of users, would have to be suggested to the less skilful user by the visual appearance.
  • the folder mechanism 1 shown in perspective in FIG. 1 with the aid of an exploded sketch is provided with brackets for lining up perforated sheets.
  • the brackets are each divided into a left bracket part (not shown) and a right bracket part 2b, 3b in their upper region.
  • the dividing joint is located to the right of the middle of the bracket, so that the right bracket parts 2b, 3b have the shape of alignment pins bent slightly towards the center of the mechanism in their upper part.
  • the bracket parts of one side are each attached to a common carrier plate 4.
  • These carrier plates 4 are pivotally connected to the base plate 5 of the mechanism. This pivotable fastening takes place in that the projections 13 provided on the carrier plate 4 engage in the recesses 14 provided in the base plate 5.
  • the base plate 5 is provided with a longitudinal rail 6 which extends upwards in the middle of the base plate.
  • the carrier plates 4 cover the base plate between the elevation 7 and the longitudinal rail 6.
  • the carrier plates 4 can each be pivoted about an imaginary axis lying in the region of the elevation 7.
  • the actuating lever 8 is by means of an axis 9 passing through the bores 9a, 9b at the rear end of the Longitudinal rail 6 pivotally mounted.
  • FIG. 2 shows a second embodiment of a file mechanism which corresponds in its essential features to that of FIG. 1.
  • the actuating lever is designed here as a bracket 80 which is open at the top and has two legs 80a, 80b.
  • the pivotable attachment of this lever with the longitudinal rail of the mechanism is done in an analogous manner as described in Fig. 1.
  • a lock 100 for locking the lever 80 is provided at the free end of the longitudinal rail.
  • the front part 101 of the latch 100 is inserted into a recess 61 in the longitudinal rail 60. Between the end face of the front part 101 of the latch 100 and the base of the recess 61 in the longitudinal rail 60 there is an intermediate space in which a compression spring 70 is located.
  • the latch 100 is designed such that there are two locking edges 220, 230 at different heights, which can interact with a locking pin 240 present between the two bracket halves of the lever 80.
  • the locking pin 240 is in engagement with the lower locking edge 220 of the latch 100.
  • the latch is pressed into the longitudinal rail 60 by finger pressure on its end face 105 against the pressure of the spring 101.
  • the locking pin 240 is disengaged from the locking edge 220 and the lever 80 pivots upwards due to the compression springs present between the support plate and the base plate.
  • the locking pin 240 passes through the slot connecting the two locking edges 220 and 230 and finally comes into engagement with the upper locking edge 230, and a further pivoting movement of the lever 80 is blocked.
  • FIG. 3 shows the side view of a folder mechanism, which is equipped with a pivotable lever 108 which, like the lever 80 from the exemplary embodiment shown in FIG. 2, is designed as an upwardly open bracket.
  • this lever is pivotably mounted by means of an axis 109 relative to the longitudinal rail 106 of the mechanism.
  • the position of the lever 108 in the closed state of the mechanism is indicated by a solid line, while the position of the lever 108 in the open state of the mechanism is indicated by a dash-dotted line.
  • the locking pin 140 can also be seen in FIG. 3.
  • the locking pin 140 is connected to the longitudinal rail 106 of the mechanism. This detail can be seen from FIGS. 6 and 7.
  • the locking pin 140 is inserted in a bore 107 provided in the longitudinal rail 106.
  • the diameters of the locking pin 140 and the bore 107 are coordinated with one another in such a way that the pin 140 is firmly and immovably seated.
  • the locking takes place in that, when the mechanism is closed, the projecting ends 141, 142 of the locking pin 140, which in each case form the locking projections, are in engagement with the upper edges 143, 144 of the bracket halves 108a, 108b of the lever 108.
  • the ends 141, 142 of the pin 140 thus act as locking projections.
  • the locking projections 141, 142 can logically also be formed directly on the contour of the longitudinal rail 106. In this version, the pin 140 would be omitted.
  • Fig. 6 the mechanism is shown in the closed state, ie the lower edges of the bracket halves 108a, 108b of the lever 108 each press the inner edge of the support plate 4 facing the longitudinal rail 106 against the force of the compression spring 11 downward into a position parallel to the base plate 5.
  • the brackets 3 are each in a position perpendicular to the base plate 5, ie the mechanism is closed.
  • the lever 108 is held in the depressed position by the locking pin 140, ie more precisely by its projecting ends 141, 142.
  • FIG. 7 shows the folder mechanism equipped with a closure according to the invention in the open state. It can be seen that the engagement of the upper edges 143, 144 of the lever 108 with the projecting ends 141, 142 of the locking pin 140 has now been released by the fact that the clear distance between the legs 108a, 108b of the lever 108 increases at least in the region of the locking projections has been.
  • the unlocking of the mechanism is thus carried out by spreading the lever 108, which is spread out by pushing the two legs 108a, 108b of the lever 108 apart.
  • the lever 108 undergoes an elastic widening and assumes the shape shown in dash-dot line in the top view of FIG. 4.
  • the wedge-shaped body designated by reference number 112 is part of an actuation rocker in the preferred embodiment, as will become clearer below.
  • the wedge-shaped body 112 is part of an actuation rocker in the preferred embodiment, as will become clearer below.
  • the legs 108a, 108b of the lever 108 are pressed into the position shown in FIGS. 6b and 7 and 7a. In this way it is achieved that the mechanics can be unlocked by exerting pressure from top to bottom on the wedge-shaped body 112, that is to say the operating element, as required in the task.
  • the design of the actuating element that is to say the actuating rocker 115, which carries the wedge-shaped body 112 required for unlocking, can be seen in FIG. 5 and the functional interaction with the other components of the mechanism can be seen in FIG. 3.
  • the operating element 115 is designed in the form of a rocker which can be pivoted about an axis 116 with respect to the lever 108.
  • the axis 116 in turn is pressed into a bore 117 (FIG. 4) which extends through both legs of the lever 108.
  • the downwardly projecting part 118 of the rocker 115 is received in the space 108c between the legs 108a, 108b of the lever 108.
  • the top 119 of the rocker 115 has a greater width than the downwardly projecting part 118, so that a peripheral edge 120 trains.
  • This edge 120 defines the positions between which the rocker 115 can be pivoted with respect to the lever 108, at most by resting on the top of the lever 108. The edge thus prevents the rocker 115 from being pivoted into a position which is lower than the upper edge of the lever 118.
  • the rocker 115 In the part adjacent to the locking pin 140, the rocker 115, more precisely the part 118 of the rocker 115 projecting downward, is wedge-shaped formed and accordingly represents the wedge-shaped body 112 required for spreading the legs of the lever 108 (Fig. 6a, 6b, 7a). To open the closed mechanism (solid line in Fig.
  • a solid reference level is additionally indicated with a dash-dotted line in order to make the movement of the lever 108 together with the rocker mounted thereon visible relative to the base plate.
  • the wedge-shaped body 112 present on the front part of the rocker 115 (FIG. 6b) is pressed in, the two legs of the lever 108 are pressed apart, so that the upper edges 143, 144 of the legs 108a, 108b of the lever 108 are the locking projections 141, formed by the pin 140. 142 of the longitudinal rail 106 can pass.
  • the mechanism springs under the pressure of the springs 11 into the open position (FIGS. 7, 7a).
  • the front part of the rocker 115 facing the longitudinal rail 106 of the mechanics is provided with a projection 130 (FIG. 5), which is intended to be inserted into an end face of the longitudinal rail 106 To protrude recess 131 (Fig.3).
  • the upper edge of the projection 130 of the rocker 115 is in contact with the edge 132 of the recess 131 of the longitudinal rail 106. Since the peripheral edge 120 of the rocker 115 prevents the rocker from pivoting further than the position shown in dash-dotted lines in FIG. 3, the opening position of the lever 108 is limited to the position also shown in dash-dotted lines in FIG. 3.
  • the stop formed by the projection 130 and the edge 132 has an additional effect when closing the mechanism.
  • the closing of the mechanism is namely effected by finger pressure on the rear part of the rocker 115, designated by the reference number 122 in FIG. 3.
  • This position for the finger pressure also corresponds to the spontaneous logical sensation of the user, since this rear part of this rocker 115 rises upwards when the mechanism is open.
  • the actuating rocker 115 acts as a lever for strengthening the mechanism when the mechanism is closed.
  • the path that the rear part of the rocker travels with respect to the lever 108 between the open and the closed position is used as an additional active path for causing the pivoting movement of the lever 108 about its axis 109.
  • the movement of the rocker thus represents a translation for the movement of the lever 108 under the finger pressure on the point 122 during the closing process.
  • the lever 108 can spring back into its original position, since the legs 108a, 108b of the lever 108 have been spread under an elastic deformation of the bow-like lever 108 . This springing back of the legs 108a, 108b into the original position is associated with an engagement which is clearly audible to the user.
  • closure according to the invention is described in cooperation with a file mechanism of the type shown in FIGS. 1 and 2.
  • the closure according to the invention can, however, also be used for file and ring binder mechanisms of another type.
