Definitions

  • the invention relates to a self-inking stamp having a preferably housing-shaped lower part that can be placed on the surface to be stamped, a linearly guided stamping insert that can be displaced against the force of the spring against the contact surface and carries a pressure plate or the like.
  • stamp insert and one of two swivel arms mounted in the lower part held, even the ink supply receiving ink roller, which rests in the rest position of the stamp insert under the action of a return spring assigned to the swivel arms on the edge of the stamp insert opposite the swivel bearing of the swivel arms, during its movement toward the contact surface by the swiveling of the swivel arms thereby forced, with ink being transferred the pressure plate or the like rolls and finally evades the stamp insert sideways.
  • Such a self-inking stamp is already known (DE-AS 1 020 648).
  • the inking roller is not only held at the free ends of the swivel arms, but with its elongated axis is guided on both sides in slits of the two opposite walls of the lower part that are oblique to the direction of movement of the stamp insert, the swivel levers also having no holes for the inking roller, but with a fork two tines are formed.
  • the inking roller therefore executes a longitudinal movement in the oblique slots of the lower part side walls on the one hand, and on the other hand between the fork-shaped prongs of the pivot levers.
  • the swivel levers have a common swivel axis, but they are not rigidly connected to it, but merely screwed onto the axis, the swivel lever also lie outside the lower part. Finally, the pivot bearing of the pivot lever is arranged in the projection onto the mounting surface within the stamp insert or even the pressure plate attached to it.
  • the two swivel arms Since the two swivel arms have no rigid connection with one another, they can to a certain extent carry out swivel movements independently of one another, which can give rise to jamming or tilting of the inking roller in their guides. Due to the arrangement of the swivel axis of the swivel arm above the stamp insert or the pressure plate, the swivel arms inevitably come into a position in the stamp movement in which they are aligned with the contact surface, i.e. are in a certain dead center position, which allows the swivel arms to move smoothly with the Ink roller inhibits.
  • the invention is therefore based on the object to eliminate these deficiencies and to provide a self-inking stamp of the type described, in which full functional reliability is guaranteed with regard to the pivoting lever movement, a simplified construction is achieved and the ink roller can be replaced easily and without risk of contamination for the operator is.
  • the invention solves this problem first in that the two pivot arms lying in a known manner within the side walls of the lower part are connected by a transverse part forming their pivot shaft to a rigid bracket, the pivot bearing, as is also known per se, in the projection the contact area is arranged next to the edge of the stamp insert parallel to the inking roller.
  • the simultaneous and uniform swiveling movement of both swivel arms is ensured, so that there can be no jamming or jamming, especially since the inking roller is only supported on the swivel arms and no additional slot guide or the like in the lower part needs, which also entails a corresponding design simplification.
  • the pivot bearing of the bracket is arranged in the projection onto the contact surface next to the edge of the stamp insert parallel to the ink roller, a dead center position is avoided during the entire pivoting movement of the bracket or the pivot arms, so that no malfunctions can occur.
  • the swivel arms or brackets are or is arranged within the housing-shaped lower part, so that when the stamp is used, these otherwise disruptive moving parts are covered and invisible.
  • the swivel bearing of the bracket is formed by at least one approximately half-shell-shaped extension of the housing wall of the lower part; the cross part of the bracket forming the swivel shaft therefore only needs to be inserted into this half-shell. Since the housing-shaped lower part will usually be made in two parts, it is then expedient to use the other Provide housing part noses or the like. In order to prevent the inserted swivel shaft from escaping from the half-shell-shaped attachment.
  • one of the two pivot levers at its free end has a bore for receiving a journal of the inking roller, which has a widened head which can be elastically compressed by slitting, whereas the other pivoting lever is provided with a bearing hole corresponding to the ink roller size diameter.
  • the housing-shaped lower part has insertion or ejection holes in its side walls in the region of the pivoting movement path of the inking roller.
  • the inking roller could be stored directly in the bearing hole with the width corresponding to the inking roller size. However, due to the comparatively large diameter, this would also result in high frictional forces between the bearing hole wall and the roller part stored therein.
  • the invention is further developed the ink roller with a rotatable on a pin with a slotted head disc in the bearing hole of the pivot lever in question.
  • every new ink roller at the end with the rotatable disc has a handle attachment with a predetermined breaking point.
  • the inking roller is thus gripped at this handle attachment and inserted into the stamp or into the bracket, after which the handle attachment is then broken off.
  • Several inking rollers with a handle attachment can be packed together as a supply. There is no need to worry about getting dirty when ejecting the used ink rollers, since they only need to be pushed out of the stamp with a suitable tool.
  • the self-inking stamp has a housing-shaped lower part 1 which can be placed on the surface to be stamped, and a stamp insert 3 which is guided in a straight line and can be displaced towards the contact surface against the force of a spring 2 and which carries a pressure plate 4 or the like.
  • a stamp insert 3 which is guided in a straight line and can be displaced towards the contact surface against the force of a spring 2 and which carries a pressure plate 4 or the like.
  • two swivel arms 5 are arranged, which are connected to a rigid bracket by a transverse part 6 forming their swivel shaft.
  • the pivot bearings of this bracket 5, 6 are formed by approximately half-shell-shaped lugs 7 of the housing wall of the lower part 1.
  • the swivel bearings or the half-shells 7 are arranged next to the stamp insert 3, as can be clearly seen in FIG. 1.
  • the pivot arms 5 hold an inking roller 8 which, in the rest position of the stamp insert 3 drawn in solid lines in FIGS. 1 and 2, bears against the edge of the stamp insert 3 opposite the pivot bearing 7.
  • the swivel arms 5 and the bracket 6 are or is under the action of a return spring 9, which tends to move the bracket upwards, i. H. to press the ink roller 8 against the pressure plate 4.
  • the inking roller 8 rolls over the pressure plate 4 and finally evades the stamp insert 3 (dashed position according to FIGS. 1 and 2).
  • the lower part 1 For mounting or for ejecting the inking roller 8, the lower part 1 is provided in its side walls in the region of the pivoting movement path of the inking roller 8 with insertion or ejection holes 10.
  • One of the two pivot levers 5 (the right one in FIGS. 2 and 3) has at its free end a bore 11 for receiving a bearing journal 12 of the inking roller 8, which has a widened head 13 which can be elastically compressed by slitting.
  • the other (left) pivot lever 5 is provided with a bearing hole 14 corresponding to the ink roller size diameter, the ink roller 8 being mounted in the bearing hole 14 of the respective pivot lever 5 with a disk 16 which can also be rotated on a pin 15 with a slotted head.
  • the inking roller 8 or the rotatable disk 16 is equipped with a handle attachment 18 connected to it via a predetermined breaking point 17.
