Definitions

• the invention relates to a perforator with a lower part that can be set up on a base, at least two perforated units that are adjustable on the lower part with respect to one another, each having a perforated die, an insertion slot and a punch, and a pivotally mounted or displaceably guided on the lower part , preferably designed as a pressure lever for moving the punch, and a scale in the area in front of the insertion slots of the perforating units, which extends over the insertion length of the lower part, for adjusting the spacing between the perforating units.
• the invention is based on the object of improving the multiple hole punch of the type specified at the outset in such a way that the setting of different hole spacings between the hole units is simplified by a clear scaling of different predetermined hole patterns.
• the invention is based on the knowledge that a multiple hole punch of the type mentioned can be used for a large number of different hole spacings and that it is therefore advantageous if the scales required for this purpose are arranged directly and captively on the hole punch.
• the scale carrier with its upward-pointing scale projects beyond the edge opening of the lower part and can be assigned to the various scales. not specified or locked positions on the lower part.
• the scale carrier advantageously has the shape of a round bar, but can also be designed as a polygonal bar or as a flat bar.
• a further advantageous embodiment of the invention provides that axially central bearing journals are arranged, preferably integrally formed, at the ends of the scale carrier, which engage in journal bearings which are non-rotatably connected to the lower part. It is expedient to design at least one of the journal bearings as a bearing sleeve which can be detachably fastened to the lower part and is preferably snap-in. Spring-supported latching means for locking the scale carrier in the predetermined rotational positions are advantageously arranged between at least one of the journal bearings and the scale carrier.
• a flexible resilient tongue can be formed on the bearing sleeve, which is preferably made of plastic, and which has a latching cam which engages radially and is arranged in a manner distributed over the circumference of the scale carrier.
• the snap-in depressions are advantageously elongated in the axial direction of the scale carrier.
• the locking means can be arranged in an eccentric, axially parallel recess in the journal bearing, preferably the bearing sleeve.
• spring-supported detent ball and a number of detent recesses arranged circumferentially distributed over the end face of the scale carrier facing the relevant journal bearing can be formed in the radial spacing of the detent ball.
• one of the bearing journals extends through the associated journal bearing, preferably through the bearing sleeve and, on its part projecting beyond the journal bearing, has a preferably glued-on, glued to the scale carrier Wearing rotary knob.
• the scale carrier expediently consists of longitudinally divided, mutually mirror-complementary rod halves that can be locked and / or glued to one another, the rod halves being expediently designed as identical injection-molded parts made of plastic.
• an additional stop rail is provided on the lower part, which is longitudinally displaceable parallel to the scale carrier and can be snapped into place in different orders, which protrudes vertically above the lower part has the stop for a side edge of the document to be punched.
• Figure 1 is a front view of a multi-hole punch with rotatable scale carrier and stop rail in a diagrammatic representation.
• FIG. 2 shows a rear side view of the multiple punch in a partially broken diagram
• FIG. 3 shows the scale carrier with bearing sleeve and rotary knob according to FIG. 1 in a diagrammatic exploded view
• Fig. 4 two scale carrier halves in a graphical representation.
• the multiple hole punch shown in the drawing essentially consists of a lower part 10 which can be set up on a base, a pressure lever 18 which is pivotably mounted on side walls 12 of the lower part 10 about a horizontal axis 14 and has a handle 16, several at adjustable intervals from one another on the lower part 10, there are perforated units 20, a scale support 24 arranged in an elongated open-edge recess 22 of the lower part 10 about its longitudinal axis and one in a side open recess 26 of the lower part 10 arranged longitudinally displaceably, stop rail 30 having a side stop 28 for the writing material.
• the perforated units 20 can be pushed onto a square rod 34 made of glass fiber reinforced plastic with a square opening 32 and can be clamped at any position along the square rod 34 by means of a set screw 36.
• a clamp holder 38 is eccentrically arranged on the hole bottom part, which has an upwardly open, through opening 40 for receiving the square rods 34 and an adjusting screw 42 which engages in the opening 40 and can be tightened against the square rod.
• the individual perforation units 20 have in their lower area an insertion slot 44 for the documents to be perforated, a perforation die 46 and a return spring with a snap ring 50 held against an upper end stop 52 by the action of a return spring designed as a helical compression spring 48, with its upper end de 54 on the punch unit 20 protruding punch 56.
• the hole punches 56 can be pressed against the surface by pressing down the pressure lever 18 with the aid of the pressure bar 66 arranged on it for the purpose of a hole process through the insertion slot 44 and the hole die 46 Force of the return spring 48 to be moved down.
• a holder 58 is additionally formed on the lower part 10, which has a vertically oriented guide for a plunger 62 which bears against the pressure web 66 of the pressure lever 18 under the action of a support spring 60.
• the spring-supported plunger 62 ensures that the pressure lever 18 is lifted in its upper end position from the rear ends 54 of the punch 56 held against its end stop 52 to form a free space 64 between the punch ends 54 and the pressure web 66.
• the punching units are set free of pressure and can be easily adjusted in their mutual spacing within the lower part.
• the structural unit consisting of square rod 34 and perforated units 20 can be removed with a handle from the lower part or inserted into it after loosening the set screw 42.
• the scale carrier 24 has the shape of a round rod, on the ends of which axially projecting bearing journals 68, 70 are formed.
• the round rod with the integrally formed bearing journals 68, 70 is expediently made of plastic by injection molding in the form of two longitudinally divided rod halves 25 (FIG. 4), which are locked together and / or glued together to complement the solid rod.
• a plastic injection-molded part is placed on the longer journal 70 trained bearing sleeve 72 pushed on and secured at the end with a knob 74, which is attached to the bearing journal in a rotationally fixed manner, preferably glued, to prevent it from falling out.
• the scale carrier 24 preassembled in this way is then inserted into the open-ended recess 22 of the lower part 10 and inserted with its bearing pin 68 into a bearing bore 76. Furthermore, the bearing sleeve 72 is locked with its locking tongue 78 in a locking recess, not shown, of the lower part 10 in a rotationally fixed manner. On the bearing sleeve 72 there is also a spring tongue 80 a ⁇ gefor t, at the free end of which is arranged a radially inwardly facing latching cam 84 which can be latched into latching recesses 82 of the scale carrier 24.
• the scale carrier 24 can thus be locked on the lower part 10 in various predetermined rotational positions, in which certain scales 24 * point upwards.
• the invention relates to a hole punch with a hole lower part 10, at least two hole units 20 which are adjustable in their mutual spacing and a pressure lever 18 pivotably mounted or displaceably guided on the lower part 10 Moving the punch 56 arranged in the perforated units 20.
• a recess 22 which extends over the insertion of the perforator and is elongated upwards and elongated which has a scale carrier 24 rotatable about its longitudinal axis is arranged, which bears several scales 24 pointing upwards in different rotational positions and visible through the edge opening.
• the scale carrier 24 expediently has the shape of a round rod, which can be snapped onto the lower part 10 in predetermined rotational positions.
