Definitions

  • the invention relates to a stapling mechanism for loose-leaf files, consisting of an elongated, flat support plate, on which at least two upright, two-part, each consisting of a fixed ironing bar and a stirrup part which can be pivoted about a vertical axis in the position of use, are arranged at a standardized distance from one another , wherein the pivotable bracket parts each have crank arms at the height of the support plate, which are connected to one another by a longitudinally displaceable connecting member and are operable together.
  • both the carrier plate and the three-part stirrups each consist of metal parts.
  • the three-part handle are each formed from a cylindrical, vertically attached to the support, a tubular, also vertically attached to the support, parallel to the hollow bar bracket guide and a movable bracket, which has two parallel, different lengths of legs, of which the shorter one freely and over one Yoke is connected to the longer leg.
  • the longer leg is longitudinally and rotatably guided in the bracket guide, the free lower end of the shorter leg being engageable with the upper end of the hollow rod.
  • the lower ends of the longer legs of the movable stirrups are each provided with a right-angled, outwardly directed lever arm, for which a number of fixed control slots corresponding to the number of stirrups is arranged in the carrier. These consist of a lower, vertical slot part and an upper, horizontal slot part.
  • a slide rod is provided which is displaceable with respect to the carrier and which has control slots which run obliquely to the plane of the carrier and into which the lever arms engage.
  • all of the stirrups can be actuated jointly by actuating the slide rod connecting them.
  • the invention has for its object to provide a simple, inexpensive to manufacture tacking mechanism of the type mentioned, which ensures simple and functionally reliable handling, in particular with regard to opening and closing the tacking bracket, which is constructed in a space-saving manner and which can be easily carried out on any Stapler or folder spine is attachable.
  • the stapling mechanism marked in this way consists of a minimum of individual parts that can be assembled very simply, functionally and can be manufactured very inexpensively using the injection molding process.
  • the movement-transmitting parts in the cross section of the carrier plate are accommodated in a space-saving manner and protected against external influences.
  • the crank arms since they do not have to be directed outwards and the cavity can be wide, can be designed to be relatively long, so that a precise transmission of movement from one movable bracket part to the other is ensured even with customary manufacturing tolerances.
  • the tacking bracket parts are locked so that there is no need to fear an unwanted opening of the bracket.
  • Another advantage is the fact that no additional actuator is required for opening and closing the handle, that it is rather possible to cause the opening or closing movement of the movable bracket parts by touching a bracket part and in the desired Direction twisted.
  • the embodiments of the locking device or the locking device according to claims 2, 3, 4 and 5 have the common advantage that they each require at most one additional functional element, namely the role or the locking member, and that they are both easy to install and simple and are easy to handle.
  • the handling and operation of the stapling mechanism can be significantly facilitated by the fact that it is provided according to claims 6 and 7 with a spring element, which causes the opening pivoting movement of the tacking bracket when manually releasing the locking device.
  • the arrangement and design of the spring element according to claim 7 still has the advantage that no additional costs and no additional space are incurred. Due to the design of the stitching mechanism according to claim 8, the assembly of the movable bracket parts in the base plate is very simple, in that they only need to be pushed from below through the bearing holes provided in the support plate or into them in order to automatically lock in their functional end position .
  • the configuration according to claim 9 makes it possible to have a shorter length of the carrier plate or of the cavity provided in the carrier plate, in which the crank arms and the Crank rod are housed to achieve. This is particularly important if the carrier plate is provided with rivet eyelets that have a prescribed standard distance from one another! must have so that they can be mechanically attached to a folder spine.
  • FIGS. 1 through 6 including one embodiment
  • FIGS. 7 through 13 showing the other embodiment.

  • Fig. 4 From Fig. 4 it can be seen that the contour of the cavity 4 and its depth is shaped such that both the crank arms 26 and the coupling rod 35 can be accommodated in this cavity 4 with the necessary freedom of movement completely sunk, such that the bracket parts 21 can be rotated by an angle .alpha. Of approximately 80 to 90.degree. From the closed position of the shackle indicated in dash-dotted lines in FIG. This twisting for opening and closing the handle 18 and 19 can be done in such a way that one of the two bow 22 is manually rotated from one position to the other, while the other pivotable bracket part through the connection via the coupling rod 35 synchronously is also rotated.
  • a latching device 38 is provided.
  • This locking device 38 consists of a double roller 39 which is rotatably mounted with a cylindrical bearing pin 40 in a U-shaped bearing slot 41 of a cam-like projection 42 of the coupling rod 35 and which engages in a circular arc-shaped recess 43 of the longitudinal boundary surface 44 of the cavity 4.
  • a slot 45 extending approximately three quarters of the length of the coupling rod, the web-like section 46 of the coupling rod 35 made of plastic, on which the double roller 39 is mounted, can be deflected in the transverse direction in a spring-elastic manner, but on the other hand the double roller 39 can also be non-positively locked in the recess 43.
  • the coupling rod 35 does not perform a linear but an arc-shaped movement during the pivoting movements of the crank arms 26, in the opening direction, which is indicated by the arrow 47 (FIG. 4), there is a corresponding depression in the wall surface 44 of the cavity 4 in addition to the latching recess 43 48 is provided, which adjoins the circular arc-shaped locking recess 43 via a cam-like elevation 49.
  • This cam-like elevation 49 must be overcome when the staples 18 and 19 are opened with a corresponding deflection of the web-shaped section 46 while simultaneously overcoming the elastic restoring forces and also during the closing movement.
  • the double roller 39 is in the region of the depression 48, it sets the further movement of the coupling rod 35 no more resistance.
  • a simple locking cam could be provided as the locking element.
  • the same reference numbers are used for the parts which are also present in the embodiment of FIGS. 1 to 6 described above.
  • the two-part tacking brackets 18 and 19 are arranged in a flat carrier plate 3/1 made of plastic in basically the same way as in the above-described embodiment of FIGS. 1 to 6.

  • rivet holes of the base plate 11 are not arranged directly in the carrier plate 3, there these rivet holes have no influence on the length of the cavity 4 of the carrier plate 3.
  • rivet eyes 51 are required in each case for accommodating the rivet holes 50, which rivets also have the length of the 3/1 in the carrier plate shortened cavity 4/1, which is open on the underside and nevertheless extends in the longitudinal direction on both sides beyond the tacking brackets 18 and 19, in comparison to the length of the cavity 4. This means that there is less space available for the pivoting movements of the crank arms 26 and 26/1 of the movable bracket parts 21 which are arranged at a distance a from one another, that is to say for the frontal limitation of the cavity 4/1.
  • a coupling rod 35/1 is provided for connecting the two crank arms 26 and 26/1, the bearing bores 37/1 receiving the pivot pins 36 have a spacing c from one another which is approximately the same amount smaller than the spacing a of the two tacking brackets , which corresponds to the length difference between the cavity 4 and the cavity 4/1. It must be accepted that the angular accuracy in the movements of the two crank arms 26 is no longer guaranteed. However, this is not disadvantageous for the handling of the stitching mechanism 2/1, rather it is achieved that the movable bracket parts 21 can also be pivoted at least approximately in this embodiment by the same opening or closing angle p (.
