Definitions

  • the invention relates to a rod guide of a rod lock of the type specified in the preamble of claim 1.
  • a rod guide is known from German utility model 7 621 270.
  • a screw is arranged in a hole in the door leaf so that its head rests on the visible side of the door leaf, and is preferably welded to it on the inside by spot welding.
  • the screw head visible from the outside affects the visual appearance of the door leaf.
  • the relatively thin door panel can warp and the welding heat can also lead to visual changes in the door painting, so that either the welding is carried out before painting the door leaf, which is difficult in the area of the screw head, or a door that has already been painted must be reworked .
  • the drive rod is guided in a radial breakthrough near the shaft end of the screw, inaccuracies in the axial alignment of the rod and breakthrough axes can be moved back and forth as a result of lever forces of the screw shaft occurring due to increased one-sided friction between the rod and the breakthrough are, at least the breakthrough fades, but also the door panel in the area of the screw head can be deformed.
  • the invention is therefore based on the object to design the rod guide so that the visual appearance of the door leaf is improved, damage to the door leaf that occurs as a result of welding the bolt no longer occur and damage to the door leaf and the rod guide itself largely caused during operation of the closure due to inaccuracies are avoided.
  • the invention makes use of the stud welding known in welding technology, in which no markings occur on the back of the sheet metal.
  • the melt residues that still occur in the area of the stud welding (welding edges) can be covered by the plastic block.
  • the widened foot part of the plastic block largely compensates for lever forces that occur during operation of the closure, so that the sheet cannot be deformed. Due to the certain flexibility of the material, the block's contact with the door panel is ensured on all sides even if the bolt is not welded absolutely perpendicular to the plane of the door's inner surface or the inner surface in the area of the weld is not exactly in the plane of the door leaf. If, according to a development of the invention, the foot part has an undercut to form a resilient foot edge, damage in the area of the fastening between the bolt and the plastic block is also avoided.
  • the plastic block could have a cavity for receiving the bolt, in which several, preferably two, embedded in the plastic opposite, spring-like metal strips protrude so obliquely inwards that they engage in the teeth when the rod guide is attached.
  • This training enables a further tolerance compensation between the breakthrough and rod axes. It could also be axial Guide the breakthrough serving the rod have a goblet-like enlargement towards its mouths. In addition to a further tolerance compensation between the axes mentioned, this is also advantageous if the drive rods of the drive rod lock are pivoted somewhat during the actuation of the lock, which is the case with many rod locks.
  • the opening in the plastic block has a rectangular extension, the cross section of which corresponds to that of the rod end, optionally with an impeller.
  • This feature makes assembly easier because the plastic block on the bolt can be rotated and then the rod, including the impeller if necessary, is inserted laterally into the opening from the right or left, and then the rod with the plastic block back up or down into the Installation position can be pivoted.
  • the rod guide can twist around its bolts without the connection loosening in an undesired manner.
  • a conventional rod lock fastened to a door leaf 16 is shown, consisting of a locking mechanism 10 which can be actuated via an actuating square 20 projecting from the locking mechanism and from which two drive rods 28, 30 extend downwards or upwards .
  • the drive rods 28, 30 preferably have a round cross section and extend approximately to the upper or lower end 32 of the door leaf 16, see FIG. 2, in order to engage there with a nose or web 34 of the door housing 36 when the door is closed.
  • the lower end of the drive rod 28 also has an idler roller 38 which is intended to facilitate the closing of the door.
  • the drive rod 28 is guided near the end of the door leaf 16 by a rod guide 40, which will be explained in more detail below in various embodiments.
  • the actuating square 20 is rotated, as a result of which not only a locking bolt moves out and in of the locking mechanism 10, but also the drive rods 28 and 30 are displaced in the axial direction.
  • the rod 28 according to FIG. 2 is moved downward and the idler roller 38 is pushed over the web 34, as a result of which an inwardly jumping edge of the door leaf 16 presses against the frame.
  • the rod guide 40 shown in detail in FIG. 2 consists of a block 46 made of plastic, which has an opening 48 for the drive rod 28, which here has a round cross section and is intended to guide round rods.
  • an opening 48 for the drive rod 28 which here has a round cross section and is intended to guide round rods.
  • This goblet-like extension which bears the reference number 50, allows the drive rod 28 to have a limited pivoting movement within the guide formed by the opening 48, as a result of which great friction or jamming is reliably prevented without having to accept a greater play, even when the drive rod 28 is skewed.
  • the block 46 is rectangular or square in the area of the opening 48, in particular its head part 52, with rounded edges.
  • the foot part 54 with which the block 46 rests on the inner surface 56 of the door leaf 16, on the other hand is round in cross section, which enables better tilting moment support, see FIG. 3a.
  • the foot part 54 has a cylindrical cavity 58, into which an internal thread is cast, cut or pressed, or into which a threaded bushing can also be molded during its manufacture.
  • a nut-like part 60 (see FIG. 5) is provided, which can be inserted into a corresponding radial opening in the block 46. This embodiment is particularly efficient to produce and stable.
  • the Screw block 46 onto a bolt 64 with an external thread, which in turn is welded onto the inner surface 56 of the door leaf 60 by means of bolt welding technology, the area liquefied during the welding (see the surface marked black marked 66) not penetrating the wall thickness of the door leaf 16, so that a deformation and discoloration of the outer surface of the door leaf does not occur.
  • the welding bolt 64 can thus also be fastened, for example, after painting the door leaf 16 by means of the bolt welding method, and then the block 46 can be screwed or plugged on to form the rod guide 40.
  • the foot part 54 has an undercut 68, as a result of which the foot edge 70 receives a certain spring effect.
  • This facilitates the alignment of the block 46, which acts like a nut, in such a way that the opening 48 can be set exactly axially to the rod 28, without the block 46 lying too loosely or too tightly on the inner surface of the door.
  • the undercut 68 also allows all-round contact with the inner surface 56 if welding material residues hinder a flat contact during welding around the base of the welding stud.
  • a rectangular extension 72 is used for this purpose, the dimensions of which correspond to those of the cross section of the flattened end of the rod 28 (not shown).
  • the cross-section of this rectangular extension 72 can also be chosen so large that even the impeller 38 can be pushed through it, so that the impeller does not have to be installed subsequently.
  • the spring action for the lugs 74 can be produced in that these lugs 74 are formed on a web 82 which is produced by a U-shaped incision 84 in the rear region of the cavity 158 in the wall of the block 46 delimiting this region.
  • FIG. 7 shows an embodiment in which the bolt 264 has teeth 86, for example a thread, as is also present in the welding bolt shown in FIG. 2.
  • teeth 86 for example a thread
  • the teeth formed by this thread 86 now engage when plugging the block 46 spring-like in the plastic of the block 46 opposite embedded metal sheet strips 88, which are injected into the plastic so that they protrude into the cavity 258 so that they protrude Place the block 46 on the bolt 264 in a barb-like manner in the teeth 86 and thereby prevent the block 46 from sliding off the bolt 264 again.
