Definitions

the invention relates to a punch with one on one Base erectable base, at least two am Lower part adjustable in their mutual distance arranged, each a perforated die, an insertion slot and punch units having a punch, a pivotally mounted or slidable on the lower part guided, preferably designed as a pressure lever Pressure element for moving the punch, and one in the area in front of the insertion slots of the hole units the insertion length of the lower part extending scale for setting the hole spacing between the punch units.
the invention is based on the object the multiple hole punch of the type specified at the beginning to improve that hiring different Hole spacing between the punch units through a clear scaling of different predetermined hole pattern is simplified.
the invention is based on the knowledge that a Multiple holes of the type mentioned for a variety of different Hole spacing can be used and that it is therefore advantageous if the necessary for this Scales clear and immediately captive are arranged on the punch.
upward open recess is arranged, and that in the recess a rotatable around its longitudinal axis Scale carrier is arranged, the several, in different Rotational positions facing upwards in the recess visible scales.
the scale carrier with its upwards pointing scale over the recess of the lower part about and can be assigned in the various scales predetermined rotational positions locked on the lower part or snapped into place.
the scale carrier has advantageously the shape of a round rod, can however also designed as a polygonal rod or as a flat rod be.
Another advantageous embodiment of the invention provides that axially central at the ends of the scale carrier protruding journal arranged, preferably are integrally formed, which are non-rotatably connected to the lower part Intervene pin bearing. It is advisable at least one of the journal bearings as releasable on Lower part attachable, preferably snap-in bearing sleeve to train. Between at least one of the journal bearings and the scale carrier are advantageous spring-supported locking means for locking the scale carrier arranged in the predetermined rotational positions.
a flexible spring tongue be molded into one over the scope of the scale carrier arranged arranged recesses has radially engaging locking cams. To despite the to ensure existing dimensional tolerances are securely engaged, the recesses are advantageously elongated in the axial direction of the scale carrier educated.
the locking means can be replaced by a in an eccentric axis-parallel recess of the Journal bearing, preferably the bearing sleeve, spring-supported detent ball and a number over the the end face of the journal in question Scale carrier circumferentially distributed in the radial distance of the locking ball arranged recesses can be formed.
the scale carrier exists for manufacturing reasons expediently of longitudinally divided, mirror images of each other complementary and locked together and / or stickable rod halves, the rod halves being useful as identical injection molded plastic parts are trained.
the multiple hole punch shown in the drawing exists essentially from one that can be set up on a base Lower part 10, one on side cheeks 12 of the lower part 10 pivotally mounted about a horizontal axis 14, a pressure lever 18 having a handle 16, several at adjustable intervals from each other on the lower part 10 arranged hole units 20, one in one elongated, upwardly open recess 22 of the lower part 10 arranged rotatably about its longitudinal axis Scale carrier 24 and one in a side open recess 26 of the lower part 10 is longitudinally displaceable arranged, a side stop 28 for the Stop rail 30 with documents.
the perforated units 20 have a square opening 32 on a square rod 34 made of glass fiber reinforced Plastic can be pushed on and by means of a set screw 36 at any position along the square bar 34 can be clamped.
the square rod 34 forms with the punched units clamped in this way 20 is a structural unit, which in its entirety in the punch lower part can be used and removed from it is. For this purpose it is off-center on the lower part of the punch a clamp holder 38 is formed, which has an open top through opening 40 for receiving the square rod 34 and one engaging in the opening 40, adjustable screw 42 against the square bar having.
the individual hole units 20 have in their lower Area an insertion slot 44 for the hole to be punched Documents, a punch matrix 46 and one under the Action of a helical compression spring 48 Return spring with a snap ring 50 against one upper end stop 52 held with its upper end 54 punch punch protruding over the punch unit 20 56 on.
the punch 56 can be depressed of the pressure lever 18 with the help of the arranged on it Web 66 for the purpose of punching through the Insertion slot 44 and the die 46 against the Force of the return spring 48 to be moved down.
a bracket 58 In the area of the clamp holder 38 is 10 on the lower part also formed a bracket 58, one vertically aligned guidance for one under the influence a support spring 60 against the pressure web 66 of the pressure lever Has 18 adjacent plunger 62.
the spring-assisted Tappet 62 ensures that the pressure lever 18 in its upper end position from the rear ends 54 the punch held against its end stop 52 56 to form a free space 64 between the punch ends 54 and the web 66 lifted becomes. This means that the punching units are depressurized and can be easily in within the lower part their mutual distance can be adjusted. Continue can thereby the square rod 34 and perforated units 20 existing unit after loosening the set screw 42 removed from the lower part with one hand or used in this.
the Scale carrier 24 on the shape of a round rod the ends of which protrude axially centrally 68.70 are molded.
the round bar with the molded bearing pins 68,70 is expediently made of plastic by injection molding in the form of two longitudinally divided rod halves 25 produced (Fig. 4), which in addition to Full rod can be locked together and / or glued.
Fig. 4 two longitudinally divided rod halves 25 produced
a rotary knob 74 which is attached to the bearing journal in a rotationally fixed manner, is preferably glued against falling out secured.
the scale carrier pre-assembled in this way 24 is then in the recess 22 of the lower part 10 introduced and with its journal 68 in a bearing bore 76 is inserted.
the bearing sleeve 72 with its locking tongue 78 in a not shown Locking recess of the lower part 10 rotatably snapped into place.
the invention refers to a punch with a punch base 10, at least two in their mutual distance adjustable hole units 20 and one on the lower part 10 pivotally mounted or displaceable guided pressure lever 18 for moving the punch 56 arranged in the punching units 20 a variety with simple and captive means set the usual hole spacing in practice can, is located in the lower part 10 the insertion length of the punch extending upwards open recess 22 in the one arranged around its longitudinal axis rotatable scale carrier 24 is the several in different rotational positions pointing upwards, visible through the recess Scales 24 carries.
the scale carrier 24 has useful the shape of a round bar, given in Rotational positions on the lower part 10 can be locked.
