• the outer channel 370 abuts one end 378 against a stop 380. Accordingly, when the button 328 is pressed, it is not the outer channel that moves downward but the upper part 320; however, since the device is generally not supported, but held freely in the hand, the jolt generated by the quite powerful leaf spring 372 is partly damped by the main spring 362 and partly by the hand itself. A separate damper can optionally be provided.

• the hooks automatically snap back into place.
• the key 330 is biased by the spring 335 into its rest and latching position.
• the described inactivation of the stapling mechanism serves primarily to avoid that a clamp is lost with every other actuation of the upper and lower shells, for example when punching or operating the scissors.
• the chosen construction, in which the outer channel is sunk in the upper part, is advantageous in that it also inactivates the hard stapler spring 372, which would otherwise counteract the operation of the punch or the scissors.
• the device becomes compact when closed.
• the sheet (or sheets) to be punched is inserted with the marking downward into the slot 410, the light guide 344 making it possible to see the marking from the outside; the light guide is provided with an arrow or the like and is aligned with the punch axis. It goes without saying that the light guide is not necessarily guided from below to the stamp stage, because in one variant it could also protrude from above onto the paper (the terms “above” and “below”, as already explained, only refer to the drawing) relate, but not to the position of use of the device).
• the light guide 344 there could simply be a hole through which one could see the inserted paper.

• the cross section of the light guide is preferably rectangular.
• the punch 412 is guided in a perforated bracket 414 and a bore or a punching hole 416 of a lug 418 to be described in detail later.
• the force transmission to the punch 412 takes place through an embossed tongue 420 of the upper part, while it is taken back upwards from the outer channel; for this purpose it is provided with a snap ring 422, inserted into a groove in the stamp.
• This construction saves space compared to the conventional design, in which the stamp is provided with a return spring.
• Upper cap 324 and lower cap 332 are plastic parts, preferably molded from impact-resistant plastic, while the other parts of the skeleton are preferably made of metal or chrome steel, each as stamped and bent parts are made.
• the upper part 320 is triple bent at right angles on both sides, so that a central section and laterally adjacent pairs of parallel flanks 424/425, 427/429 result, which form the guide channels of the displaceable tools (scissors and staple remover).
• the middle, flat section is provided with recesses and deformations, the purpose of which will be explained later.
• the inner bent flanks 424 and 427 are extended to the rear ("rear" is the hole-side end) and provided with aligned bearing bores.
• the outer channel 370 has an inverted U-shaped cross-section and is provided with an angled tongue 426, to which the slide rod 402 is fastened; at the front end there are inwardly projecting tabs 401 for supporting the clip carrier.
• a breakthrough 428 enables the punch to pass through with its snap ring 422 pushed on above the breakthrough after the punch has been inserted, so that it can be operatively connected to the tongue 420 formed on the upper part in order to actuate the punch.

• the Böckchen 418 is another stamped and bent part. It supports the bearing journal 436 about which the outer channel and the upper part can be pivoted.
• the bearing pin 436 is arranged in projecting cheeks 440, below which there is a space for the insertion of papers to be punched. The vertical edges at the end of this free space form the stop 458 for placing the papers.
• the cheeks are connected by a transverse plate 442, provided with the lower punch guide and arranged above the paper slot.
• the bracket 414 is attached to the cross plate, e.g. spotted.
• the lug has a foot part 444 by means of which it is centered in the lower part, to which it is also attached by means of spot welding or clinching. The design of the upper edges of the lugs are described below in connection with the locking mechanism.
• the lower part 322 consists of two reversely U-shaped angled sheets, of which the upper sheet metal angle 446 is the die hole 448 for punching, a recess 450 for the passage of the light guide 344 and the insertion of the lug foot 444 and as a passage opening for the spring 362 and an opening 452 into which the stage 390 can be moved.
• the design of the angled legs 453, 455 will be explained later in connection with the relocatable utensils.
• the lower sheet metal angle 454 is e.g. connected by spot welding. It has an opening 456 for the passage of the punching waste of the punch and the reception of the light guide, a recess 438 for supporting the main spring 362, mounting holes 460 for the lug base, and an opening 462 corresponding to the opening 452
• the indentation 438 (FIG. 22) supports the main spring 362, the other end of which is supported on the outer channel between the punch and the tongue 426; the spring is so short in relation to its diameter that no special measures need to be taken to prevent the spring from buckling.
• the two openings 464 in the upper sheet metal angle and 466 in the lower sheet metal angle enable the vertically bent part 400 of the locking angle 396 to pass through.
• the anvil 388 which is made of hardened steel, is pressed into an insert 468, which in turn presses with the lower sheet metal angle 454 or in some other way
• the lower sheet metal angle is narrower than the upper one, so that between the angled legs 457, 459 of the inner and 453, 455 of the outer sheet metal angle a guide channel for receiving further displaceable tools (knife, cutter) is delimited.
• the lower sheet metal ⁇ angle has an incision 470 in the angled leg 459, which frees up the required lateral space for the tape measure.
• the upper part has a channel delimited by the angled flanks on both sides of the space required for the stapling mechanism, and that the lower part also has channels delimited by the pairs of legs on both sides.
• the tongue 472 is formed on a leaf spring 474 which is arranged on the upper side of the upper part 320 and is held and guided there by overlapping tabs 475.
• projections 476 on the upper edges of the lug 418 grip over lateral tabs 465 of the leaf spring 474, which come free of the projections when the button is displaced in the opening direction.
• tabs 478 molded onto it and provided with a downward-facing nose at its ends overflow onto the upper part 463 (marked in FIG. 25), so that the leaf spring can only assume two stable positions: Ver - or unlocking end position.
• a tongue 480 is cut out, which is angled downward and engages in a recess 479 of the upper part 320 in the unlocking end position.
• the leaf spring 474 cannot be moved back into the locking end position as soon as the device is opened. Only when the two shells have been brought into the closed position shown in FIG. 27, do the cams 482 formed on the lug raise the tongue 480 to such an extent that they come free from the recess 479 and the device is locked by moving the button back can; the second recess for the second cam 482 makes the lifting of the tongue 480 more even.
• the solution presented here is preferred because of its simplicity.
• buttons 328 and 330 can be pressed, but that when the device is released, the clip magazine or the clip holder snap back into place, that is, the configuration shown in FIG. 26 is retained when the device is opened.
• the trigger button 328 for the stapling mechanism is articulated at the top in accordance with FIG. 24.
• the alternative construction shown in FIGS. 31 to 33 is preferred.
• the key 328 here has a stop surface 484 with which it rests on a counter surface of the handlebar 486, which is pretensioned in the closed position by a U-shaped leaf spring 488.
• the handlebar 486 is articulated at 490 and engages under the pins 430 of the outer channel with hooks 492. As before, the handlebar locks automatically with every stitching process.
• the utensils are knives, cutters, staplers and scissors by means of appropriate attachments to them Utensils molded or overmolded guide shafts 493, 494, 495 and 496 made of metal or plastic or plastic-encapsulated metal guided longitudinally. Since the guides are very shortened in the corner areas due to the strongly rounded outer contours of the device, but in particular the highest possible stability of the tool guides is required in the worn-out positions of use, the utensils are additionally provided with sliding blocks 497, which are in guide slots 498 slide, led.
• Recesses 503 are provided in the guide shafts 493 to 496 of the utensils, in which recesses a sliding bolt mechanism for displacing and locking the utensils is arranged.
• the slide latches 318 can be connected to the slide bolt mechanism via direct connecting webs 500, which necessitates corresponding longitudinal slots 505 in the outer channel boundaries 425, 429, 453 and 455, on which the latching latches 507 for the utensils can also be arranged.
• such slots can also be provided in the base areas 511 of the upper and lower shells and - as shown in Fig. 38/39 - the connecting webs to the slide bolts in the area of the joint between the upper part and lower part U-shaped around the outer channel limitations, e.g. 453, be led around.
• Each utensil should be blocked both in the inner and in the outer end position; for deblocking, the user shifts the respective slide bolt in a direction perpendicular to the slot extension, either upwards or downwards (corresponding bolt latches can be seen in FIG. 25) or “inwards”.
• the device can be built somewhat thinner, but the operation of the slide latches is less handy.
• a construction is therefore preferred in which the unlocking is carried out by pushing the slide latch inwards. So that the push locks are not pressed in unintentionally, they lie approximately flush with the outer contour of the shell in the area concerned.
• FIGS. 34 to 37 An example of the last-mentioned construction is shown in FIGS. 34 to 37:
• the key 318 sits on a pivotable lever 500, to which a leaf spring 502 is molded, which carries a locking block 504. By pressing the button on one side, the block 504 is released from the latch 506.
• the leaf spring ensures that the block engages automatically in the end positions.
• the plastic key 318 is molded onto the metallic lever, for example molded, and the assembly is designed so that it can be fitted from outside through the slot 505.
• the button 318 is seated on a pawl 508 which is pre-tensioned a leaf spring 510 engages (FIG. 38) and is lifted out of this detent position into the release position (FIG.
• an additional safety lock could be provided, particularly for those with the risk of injury if they were pushed out unintentionally, which blocks such utensils individually or in groups.
• Such an additional safety lock is schematically shown in FIGS. 18 and 40 in the form of a rocker 512 mounted in the lower part, which is fork-shaped and engages with the arms 513 in the guide channels for the knife and the cutter, so that these are blocked in their inner end positions.
• FIGS. 44 and 45 sections along the lines AA and BB of FIG. 42 are.
• the scissors have a guided blade 520 and a blade 522 which is articulated to this at 521.
• the blade 520 is guided not only via a simple guide stone, like the other utensils, but also via a handle with an underhand grip, because blade 520 is not on the outer Can support the wall of the guide channel.
• This rear-moving stone 524 can be seen in FIG. 44. Since there must be a connection to the relevant slide bolt from the side of the sheet 520 facing away from the rear grip, the sheet 522 is correspondingly short.
• a spring-loaded hook 526 which detaches from the lower shell when the scissors are inserted and places it in a corresponding recess 528 in the sheet 520.
• An opening 527 in the lower shell allows the hook 526 to pass through; the opening 529 also serves this purpose.
• a wire spring 523 biases the sheet 522 into the open position.
• the scissors are operated by squeezing and releasing the two shells. In order to achieve the best possible rejection of the clippings, the scissors can be extended so far that the scissors joint is not congruent with the pin 436, so that a relative displacement between the blade 522 and the lower shell 302 must be provided when cutting.
• the scissor blade 522 that is taken along is approximately as long as the guided blade, but is so slim that the connection to the slide bar of the scissors can still be guided past it.
• the wire spring 530 biases the two blades in the opening direction and holds blade 522 in contact with the lower part.
• the sheet 522 that is carried along moves along the lower shell when cutting.
• FIGS. 49 to 53 A further variant of scissors is shown in FIGS. 49 to 53.
• the shearing movement is not generated by displacing the shells, but the scissor blade 522 which is carried along is actuated with the thumb, preferably when the device is closed, while the fingers hold the body.
• the sheet 522 is provided with a rotatable thumb catch 532, which at the same time keeps both sheets locked together in the insertion and removal position.
• a wire spring 534 clamps both blades in the open
• the thumb catch 532 can be brought manually into and out of the operating position or automatically fold out when the outer end position is reached, while it is manually reset for the insertion.
• a spring-loaded locking lever 536 attached to the guided blade 520, secures the scissors in the extended position after the thumb rest has been folded up and thereby pivoted out of the extension 538.
• the thumb catch When the thumb catch is folded down, it engages in the extension 538, which raises the locking lever 536 and thereby releases the locked shaving blades for insertion.
• the blade holder 552 which is preferably made of plastic, runs in a support 550, preferably made of metal, with a C-shaped cross-section, which extends a predetermined distance when the blade holder is pushed out under the action of a compression spring.
• the support serves to support the blade holder and to hold the double blade 556 in place, which can be plugged with its centering hole 558 onto the pin 554 if the blade holder 552 for replacing or rotating the double blade extends beyond the latching position of the support 550 is pushed out that the double blade is free and can be removed or inserted laterally.
• three locking positions of the slide bolt are provided: retracted, cutting, blade change.
• the blades are changed from the front.
• the double blade 556 automatically engages in the chamfered pin 560.
• the pin 560 can be pushed out of the centering hole 558 by means of the button 562 and the blade can be removed to the front.
• the staple remover 312 comprises an insertion nose 570 which is pushed on the closed side of a staple 571 to be removed between the staple and the stapled paper bundle. Laterally formed, progressively higher bars 572 press the clamp legs out of the paper. A notched tab 574 lies over the back of the clip and prevents the clip from being pulled on one side and then having to be laboriously removed manually. In the opening Rich in the guide channel that receives the staple remover, two small pins 576 are fastened on both sides of the tab 574, which strip the staple off the staple remover when it is pushed back into the upper shell.
• the staple remover is preferably bevelled on its outer side directed towards the outer channel boundary in such a way that it lies flat on the paper to be stapled when the device is slightly inclined, as can be seen in FIG. 70.
• a pointer rod 580 which consists of sleeves that can be telescopically extended.
• a release button 592 which is held in its rest position by means of compression spring 590, engages behind the sleeves 594 and pushes them outward when actuated so that the button 596 on the innermost sleeve can be gripped and pulled out.
• the pointer could also be arranged on a carriage which can be pushed out by means of a button, preferably against the force of a return spring, to such an extent that its button 596 can be gripped.
• Figures 63 to 65 show the structure in the magnifying glass area in greater detail. From the legs 457 and 459, two tabs 600 are angled inward, which serve to guide the rear extension of the magnifying frame 602. This extension is asymmetrically fork-shaped with a wider leg 604, which has a recess with a part-circular cross-section on the underside - there is space for the laser pointer 360 - and with a narrower leg 606. Between the two legs there are batteries 356; the spring that biases the magnifying glass into the open position acts on the wider leg, but is not shown for the sake of clarity, the locking button 334 is arranged above the magnifying glass, by means of which the magnifying glass is held in the lower shell. Under the magnifying glass there is a transparent insert 608 which enables the laser or lamp light to pass through.
• Figures 66 through 69 show details of the chamber 348 for the punch waste and the access door 346 for emptying the chamber. Unlike office holes, this chamber has a relatively small volume, so that the user may forget to empty the chamber in time. In order to avoid overfilling, it is provided that the user is signaled when the chamber should be emptied.
• Fig. 66 shows the closed chamber in cross section.
• a chamber housing 620 to which the flap 346 is articulated, is formed on the lower cap 332.
• the flap is in turn provided with upstanding walls which, together with the chamber housing, prevent punching waste from entering the interior of the lower shell in an uncontrolled manner.
• the flap 346 has a double snap lock. In its closed position, it engages with small cams 622 on the protruding edges 624 of the chamber housing. If the pressure load within the chamber 348 becomes too great, this first locking will give way and the flap 346 opens into the position according to FIG. 67, in which position the flap is locked again, however, namely with larger cams 626. The holding force thereof must be overcome manually. The slightly open position of the flap, in which no punching waste is released yet, signals to the user that the chamber should be emptied at the next opportunity. 68 and 69 show this emptying position of the flap 346 in cross-section and longitudinal section.
• FIG. 70 shows another embodiment variant in which the upper shell is designed as a lever which engages between flanks of the lower shell and is flush with its contours in the closed state. Front and back slits allow you to insert papers to be stapled or punched.
