Definitions

  • the invention relates to a rod lock with a releasable rod connection between the locking device, such as locking pin or idler rollers, carrying the locking rod of the locking rod and the connecting rod of the locking rod lock, the locking rod being guided through at least one rod guide and the connecting rod forming a bearing pin near its free end on which the Locking rod can be pushed open with an opening in its end.
  • the locking device such as locking pin or idler rollers
  • Such a rod lock is already known, for example from EP 0054225 A1 as well as from catalog sheets B145.2 and B145.4 of a catalog from EMKA Betschmaschine GmbH from December 1988.
  • Such rod closures with a releasable connection between the connecting rod, which is led out of the lock, and the locking rod, which the locking devices, such as in particular locking pin or Caster wheels, carries, have the advantage that they can be adapted to different cabinet heights by simply removing the locking bar with the inappropriate length by loosening the bar connection and replacing it with a locking bar having a suitable length.
  • the known rod connections work with a bolt, preferably riveted into the connecting rod, onto which the locking rod provided with a bore at its end is plugged and then a snap ring is pushed onto the end of the bolt with an annular groove in order to prevent the locking rod from moving from the bolt again.
  • the object of the invention is to improve the rod lock of the type mentioned in such a way that the rod connection is easier to manufacture and in particular easier to assemble and possibly also to disassemble.
  • the present invention enables embodiments which enable simple conversion of certain components in order to change the rod lock from, for example, right-hand operation to left-hand operation.
  • the rod connection described above is preferably provided in order to releasably connect the locking rod to the connecting rod of a rod lock.
  • the rod connection is also suitable for dividing, for example in half, a relatively long locking rod, which could cause problems during packaging, and the two sections, e.g. B. after transport during the assembly of the rod lock by means of a rod connection according to the invention again.
  • rod guides can serve anyway. If their guidance is not sufficient, further developments are possible which cause the two rod ends connected to one another to be locked against pivoting about the bearing pin.
  • the stop surface is formed by a bolt head which has a non-circular, such as polygonal, in particular square head, the central part of the bolt being circular in cross-section and this circle affecting the polygonal cross-sectional sides on the inside, the ones which can be plugged onto the bolt Rod has a breakthrough that fits over the head when the rod is aligned in at least one direction deviating from the orientation of the rods (working position). If the one rod is then pivoted to the other so that there is an alignment of the two rod axes, the bolt head holds the rod attached to the bolt.
  • a non-circular such as polygonal, in particular square head
  • connection rod of the rod lock lock is guided in the lock, which is usually such that only movement in the axial direction is possible.
  • a rod guide guiding this locking rod is then sufficient, since the rod, due to its attachment to the connecting rod, which cannot be pivoted but only axially displaceable, is also guided at a total of two points such that it only carries out an axial movement.
  • the connecting rod has a relatively strong play perpendicular to the axial direction, it may be expedient either to guide this connecting rod or to store the locking rod connected to the connecting rod by means of at least two spaced-apart rod guides.
  • a third possibility is to provide the detachable rod connection with an additional locking device which, after the two rods have been connected together, prevents mutual rotation about the bolt head by means of the rod connection.
  • This can be done, for example, that - if the rods or at least their ends are made of flat material and the connecting rod and / or the locking rod forms at least one bearing pin, onto which the locking rod (and / or the connecting rod) can be plugged by means of corresponding bores, the superimposed ones Bars are enclosed by a U-shaped bracket in cross section. If this clamp has a relatively large axial extent and also surrounds the two side edges of the rods, the stability is particularly great. It will be similarly large Stability if two bolts are arranged that are offset axially with respect to the rod axis.
  • the bolts in question here can be formed by a riveted bolt, a welded-on bolt or simply by pressing the material out of, for example, flat material.
  • a conventional bolt with a snap ring can also be used if, despite the disadvantages described at the outset, such an application is desired for certain reasons. This applies in particular to those connections which are to be protected from buckling by clasping, that is to say in those cases where two relatively long locking rod parts which are mounted with only a few, for example only one, rod guide are used.
  • Such a bracket would have a U-shape. However, if you make the bracket C-shaped, the ends of the C take over the function z. B. the snap ring and this could be omitted.
  • FIG. 11A and 11B which show a rod lock to which the invention can be applied.
  • It is a rod lock 10, which comprises a box-like rod lock 12, which is fastened by means of two fastening screws 14 to a door leaf 16 made of sheet steel, for example, and is constructed such that when a lock nut 18 is rotated counterclockwise (as seen in FIG. 11A), one Pushes the connecting rod 20 in the direction of the connecting rod axis 22 from the lock 12 to the outside (in the case of the connecting rod designated by 20 according to FIG. 11A downwards), but in the opposite direction of rotation pulls the connecting rod 12 into the lock case 12.
  • the connecting rod 20 is mounted in the lock case 12 in such a way that it can only carry out this axial movement, but not a movement perpendicular thereto, and pivoting movements are prevented.
  • the connecting rod 20 has a crank 24 at its free end, such that a locking rod 28 articulated on the cranked end 26 is substantially flush with its (preferably central) axis 29 to the central axis 30 of the lock case.
  • This has the advantage that the illustrated locking rod 28, which is driven by the connecting rod 20, is aligned with a corresponding, not shown here, arranged above the lock case 12 further locking rod which is driven by the connecting rod 21, which is only partially shown.
  • the advantage is that by turning the connecting rod 20 from the position shown to a position shown in dashed lines and designated 20 ', one Changing the direction of rotation of the nut for the closing process is made possible without the distance of the locking rod 28 from the door leaf bend 32 therefore changing.
  • the locking rod 28 is held at a certain distance from the bend 32, specifically from the rod guide 34, which is fixed here by means of a weld bolt 36 welded to the door leaf 16 and a corresponding nut 38, which rod guide 34 has an axial movement the rod 28 as well as a limited pivoting movement around the axis of the welding stud 36.
  • the end of the rod 28 which has a bore for plugging onto the bolt end, from this bolt with a slight pivoting of the locking rod fixed connecting rod
  • the bolt 40 is riveted into the cranked end 26 of the connecting rod 20 as shown.
  • a locking element here in the form of an idler roller 42 which, when the locking rod is pushed out or moved down, lies behind a bend 44 of a door frame 46 and thereby a door leaf 16 while compressing a sealing strip 48 against the door frame 46 presses and thereby closes the door leaf in the door frame.
  • the connecting rod 20 can be implemented in the lock case 12 (in a manner not of interest here) in such a way that it arrives in the position 20 'according to FIG. 11A.
  • the locking rod 28 is cranked at its lower end, as can be seen in FIG. 11B, it cannot be rotated at the same time , but it must be solved the rod connection 50, which here consists of the riveted to the cranked end 26 of the connecting rod 20 bearing bolt 40, onto which the end of the locking rod 28 provided with a corresponding round bore is plugged and then by means of an annular groove in the bolt end attached snap ring 38 is secured against falling.
  • the snap ring 38 must therefore first be removed with a special tool, whereupon the locking rod 28 is pulled off the bolt 40 and then the connecting rod 20 can be moved from the position 20 to the position 20 ', whereupon the locking rod then again pushed onto the bolt 40 and finally the retaining ring can be inserted with great effort into the annular groove of the bolt 40 using special pliers.
  • This is obviously cumbersome and also carries the risk that the circlip jumps off the special tool during manipulation and must be searched for or replaced.
  • manipulation with pliers due to the fold 32 can be difficult because the fold hinders access to the snap ring in its position shown in FIG. 11A.
  • the connecting rod 20 in turn has a bolt 140 riveted to the cranked end 26, which, similar to the illustration according to FIGS. 11A and 11B, has, in addition to the foot 52 to be riveted, a central part 54 with a circular cross section and an enlarged diameter relative to the foot on which middle part 54 the locking rod 128 with its end opening 141 (see FIG. 2A) is rotatably supported, in spite of its square cross section in this embodiment, essentially because the circular cross section of the bolt middle part 54 and the opening 141 are designed so that the circular cross section just touches the inside edges of the square.
  • the bolt 140 in contrast to the construction according to FIGS. 11A and 11B, in which the rod 28 is held by the fact that a snap ring 38 is held in an annular groove formed by the end of the bolt 40, the bolt 140 according to the embodiment from FIGS. 1A to 1C and FIGS. 2A to 2D show a head 56 with corners 58 projecting over the circular circumference of the cross section of the central part 54, the head circumference here forming a square which just fits through the opening 141 of the locking rod 128, but the square sides of which differ with respect to the axis of the connecting rod 20 Alignment than the square sides of the opening 141 with respect to the axis of the locking rod 128.
  • the offset of the two squares 56 and 58 to one another is preferably approximately 45 °, as is indicated by the angle 58 in FIG. 2C.
  • FIG. 1A which shows a plan view of the rod connection, to slide the rod 128 onto the bolt head 58 when the axis directions of the rods 20 and 128 are offset by 45 ° to one another until the opening 141 in the region of the Middle part 54 of the bolt 140 arrives, as can be seen in the side view of FIG. 1C.
  • the rod 128 can now be turned out of the position shown in FIG. 1A and, for example, brought into the position according to FIG. 1B, in which the two rod axes of the rods 20 and 128 are aligned with one another. In this position, the corners 58 of the head 56 hold the surface areas of the rod 128 running under these corners, so that the rod 128 can no longer slide off the bolt 140.
  • connection 150 is used in the case of a rod lock according to FIG. 11A, the direction of actuation of the lock can be changed without special tools in that (for example after removing the screws 14) the lock case 12 is lifted off the inner surface 17 of the door leaf 16 and thereby the possibility is given to pivot the connecting rod 20 in the direction of arrow 60 (FIG.
  • the implementation can also take place in that after loosening the screws 14, the lock case arrangement 12, which consists of two halves (see the dividing line 8), is disassembled, whereupon the connecting rod 20 can be pivoted out of the lock case 12 in the direction of arrow 60.
  • the connecting rod 20 can then be separated from the locking rod 128 in the manner already described and, after the connecting rod 20 has been moved into the new position (20 ′), can be connected again to the locking rod 128.
  • the locking rod 128 remains in place so that other fastening devices, such as the rod guide 34, do not have to be loosened or even removed.
  • FIGS. 3A and 3B each show a top view and FIG. 3C shows a side view of another embodiment of a rod connection which can be used according to FIGS. 11A and 11B, the bolt 240 here being formed by a material squeeze or slug, which is formed by corresponding punching processes in FIG the end of the bent flat material of the connecting rod 220 is attached.
  • the bolt 240 here being formed by a material squeeze or slug, which is formed by corresponding punching processes in FIG the end of the bent flat material of the connecting rod 220 is attached.
  • punching out such a slug which is a much simpler and cheaper method than riveting a bolt, it is technically difficult to simultaneously produce a polygonal head, as is used in the embodiments according to FIGS. 1A, 1B and 1C.
  • a protruding protrusion 66 extending from the (cranked) end of the connecting rod 220 in the vicinity of the bolt 240 is provided here for holding the locking rod 228 on the slug-like bolt 240, which protrudes in the working position of the rod lock shown in FIG. 3B an edge part 68 of the rod 228 comes to rest and thereby holds the rods 220 and 228 in the axially aligned position, as shown in FIG. 3B.
  • this edge part 68 can be formed from a protrusion extending from the end of the locking rod 228, or according to FIG. 5 by the regular annular surface 168 running around the bolt 140.
  • the projection 68 or the edge region 168 can be pivoted away from the region of the projection 66, in accordance with FIG. 5 this up to an incision 70 happens in the edge area, which in turn now makes it possible to separate the two rods 220 and 228 from one another, similarly to what has already been described with regard to the previous embodiments.
  • the locking rod 228 can be seen individually in a plan view and in a side view according to the embodiment of FIGS. 3A to 3C, in FIGS. 4C and 4D the associated shape of the connecting rod 220 in a plan view and in a side view.
  • the shape of the projection 66 is selected such that it can be formed in one punching step together with the slug 24 forming the pin 240 with the offset 24, so that the entire production is extremely inexpensive.
  • FIGS. 6A and 6B an embodiment has proven itself, which can be seen in FIGS. 6A and 6B and which also works by means of slug-like bolts which can be produced in the simple manner described, in this case with two slugs 70, 72 arranged axially one behind the other
  • the rods 320 and 328 are not pivoted relative to one another for the purpose of blocking or releasing them in the region of the articulation of the two rods.
  • a manually slidable, U-shaped clamping spring 84 is provided, which can be applied without special tools and also no special head shape with an annular groove for requires the bolt, as described at the beginning with regard to the snap ring.
  • this spring 84 is laterally pushed onto the connection area of the two rods, see reference number 350 in FIG. 6A that a projection 74 projecting inwards from the spring lies down in the recess 76, which automatically arises when the slugs 72, 70 are produced on the back of the flat material on the front of which the slug is produced.
  • This approach 74 starting from the spring can exist in two ways 7A), in order to penetrate into both depressions 76, 78 formed, or it is also sufficient for one such projection 74.
  • end regions 80 and 82 which can be grasped by hand, it is possible without problems to grasp the U-shaped spring 84 with the fingers, to bend them open, so that the projections 74 come out of the depressions 76, 78, and to push the spring away from the region 350, if the two rods 328, 320 are to be separated.
  • the spring 84 can also simply be pushed back on by hand, the projections 74 automatically snapping inwards into the depressions 76, 78 when the end position is reached, and thus locking the spring 84 in the position shown.
  • the projection 74 of the spring 84 can consist of a semicircular indentation, as can be seen in FIG. 7A.
  • Such a securing spring can of course also be used if there is only one slug, as shown for example in FIG. 4D, in which case the components or features 66 and 68 and 70 can be omitted.
  • a spring 184 would also be conceivable. which would be constructed similarly to the spring 84, but instead of the projection 74, which extends inwards, has an opening for receiving the end of the bolt 40 protruding beyond the rod 328, so that the spring 184 is held thereby.
  • a spring 84 or 184 in the form described is expediently made of spring steel or stainless steel.
  • a plastic clip 284 can be seen which encompasses the two rods 320, 328 in such a way that the rod 328 is held on the rod 320, under the action of inwardly projecting lugs 86.
  • FIGS. 8A, 8B and 8C can also be omitted, as can be seen in FIGS. 8A (in a top view), 8B (in a partially sectioned side view) and 8C (in a cross-sectional view), in which case however a different fuse must be provided, for example by means of a snap ring 38.
  • the embodiment shown in FIGS. 8A, 8B and 8C does not need to be made of plastic, it can also be made of metal, since here the legs of the U-shaped part do not have to spring away. There is then a relatively very high stability, so that it is possible to connect two rods 420, 428 which are to be connected to one another so as to be secured against pivoting about the bolt 40, without having to use two bolts, as is the case in FIGS. 6A , 6B and 7A, 7B, 7C.
  • FIG. 8A and 8B show an interesting detail, namely a stop lug 88 which is pressed out of the material of the connecting rod 420 and which lies with its end face 90 on the end face 92 of the locking rod 428.
  • This direct transmission of course only takes place in one direction of movement, and that is the direction in which, for example, according to FIG. 11B, the locking rod 28 is pressed down and the impeller 42 hits the bevel 44 and is pushed onto it. This creates the greatest pressure forces. In the opposite direction (when the rod 28 is pulled back and the idler roller 42 rolls down from the fold 44), however, considerably lower forces occur, so that this additional direct power transmission is not so necessary here.
  • This nose 88 which extends from the connecting rod 420, is effective in both "right” and “left” operation of the closure, i. H. the nose 88 remains effective even when the connecting rod 20 comes to rest on the other side of the locking rod 428 than is shown in FIG. 8B. This case has already been described with reference to FIG. 11A.
  • corresponding projections could also be provided on the locking rod 428 in order to strike the front edge of the connecting rod 420 and to transmit force directly.
  • a lug would have to protrude on both side surfaces of the locking rod 428, so that two lugs would have to be punched out in the same area, which weakens the rod 428 relatively strongly would, which is sometimes undesirable.
