Definitions
- Hand-held device for applying marking rings on line wires and marking device therefor
- the invention relates to a hand-held device for applying slotted marking rings from a supporting rod to electrical line wires and to a marking device therefor.
- Slotted marking rings which are preferably made of plastic, are used to mark electrical wires. So far, such marking rings have been applied by hand.
- a known supporting rod (DE-OS 30 31 987) carrying a plurality of marking rings is used, which is widened at one end to form a placement shoe which is placed with a recess over the line wire to be marked.
- One or more marking rings are pushed from the support bar over the mounting shoe onto the cable core. If the plastic rings slide over the mounting shoe, they are expanded so that they grip over the line wire.
- Pushing the slotted marking rings onto the cable cores by hand can be exhausting during long-term work, especially the thumb tip with which the Marking rings are usually pushed forward on the support rod, thereby being exposed to a considerable load.
- the object of the invention is therefore to provide a hand-held device of the type mentioned at the outset, which makes it possible to apply the marking rings to the line wires much more easily and simply.
- a hand-held device for applying slotted marking rings from a supporting rod to electrical lead wires which is characterized in that a receiving channel is arranged in a handle housing, which interchangeably receives a supporting rod equipped with marking rings, which has a front, widened end protrudes from a transfer opening of the handle housing and is anchored at its rear end by means of an anchoring device in the handle housing that an externally accessible, longitudinally displaceable slide in the handle housing is provided with a pushing claw reaching for the transfer opening for the foremost marking ring, and that one behind the last Marking ring adjacent feed body is movable along the support rod towards the front end in steps that each correspond to the width of a marking ring.
- the individual marking rings are pushed over from the supporting rod onto the cable core by the pushing claw, which is connected to the slide which can be moved longitudinally in the handle housing.
- This slide is preferably moved with the thumb of the hand holding the handle housing. Since the slider is one has sufficiently large contact surface for the thumb, the operation of this slider is much easier and more pleasant than the immediate pushing over individual marking rings with the thumb.
- the support rod is by means of
- Anchoring device held in the handle housing so that it is not pushed out of the handle housing under the action of the force exerted by the pawl.
- the feed body has a saw toothing which is in engagement with a saw toothing on a toothed rack which is guided in a longitudinally displaceable manner in the handle housing and is in drive connection with the slide.
- this rack executes a stroke and takes the feed body with it. Due to the saw toothing, the rack slides along the feed body on the return stroke without taking it along.
- a support rail which supports the support rod and is rigidly connected to the handle housing, projects under the support rod outside the transfer opening.
- This support rail takes the at Pushing the marking rings through the shear claw exerted transverse forces and prevents the support rod from sagging without it being necessary to support the support rod on the line wire to be fitted. Such bending of the support rod can occur the easier the thinner the support rod is. It should be taken into account that the thickness of the support rod depends essentially on the thickness of the line wire to be fitted and can therefore not be chosen arbitrarily.
- a marking device for use in the hand-held device according to the invention should be designed such that the support rod has a constriction at its rear end facing away from the mounting shoe.
- the constriction is preferably formed by a notch on one side of the support rod or by two notches on opposite sides of the support rod.
- the invention is based on one

- Fig. 9-11 modified embodiments of the support rod end shown in Fig. 7.
- the hand-held device shown in the drawing is used to apply slotted marking rings 2 received on a supporting rod 1 to an electrical line wire 3.
- the handheld device has a handle housing 4 divided in the longitudinal direction, which is handled in the manner shown in FIG. 6.
- a receiving channel 5 is formed, which extends from a transfer opening 6 into the handle housing 4 and receives the supporting rod 1 equipped with marking rings 2, as shown in FIG. 1.
- the support rod 1 which is widened at its front end to form a placement shoe 1 a that can be placed on the line wire 3, is fixed with its rear end 1 b in the handle housing 4 by means of an anchoring device 7.
- This anchoring device has an anchoring slide 8, which is essentially plate-shaped and can be displaced against the force of a spring 9 when one presses on a slide extension 10 of the anchoring slide 8 which is accessible from the outside.
- the anchoring slide 8 has an opening 11 through which the rear end 1b of the support rod 1 is inserted. The opening 11 tapers upwards.
- the anchoring slide 8 sits as a rider on the support rod 1, the tapered part of the opening 11 positively engaging at a point at which the support rod 1 has two lateral recesses 12 or at least one such lateral recess 12.
- a slide 13 which is accessible from the outside and can be operated with the user's thumb, is guided so as to be longitudinally displaceable.
- the slide 13 is pulled by a tension spring 14 into its rear starting position.
- the slider 13 is connected to a thrust claw 15 which projects obliquely downwards to approximately the area of the transfer opening 6.
- the thrust claw 15 which is preferably provided with a lower notch, engages behind the foremost marking ring 2 and, as will be described in more detail later, can slide this over the thickened mounting shoe 1 a onto the line wire 3 when the slide 13 moves forward.
- the end of this sequence of movements is shown in Fig. 2.
- a feed body 16 which is longitudinally displaceable in the receiving channel 5 and engages over the support rod 1 in the manner of a saddle.
- the feed body 16 has on its upper side a saw toothing 17 with teeth directed backwards, which is in engagement with a corresponding saw toothing 18 of a longitudinally movable rack 19.
- the division of the saw teeth 17 and 18 corresponds to the width of the marking rings 2.
- the rack 19 is pulled by an obliquely arranged tension spring 20 both in its starting position to the rear and against the feed body 16.
- an eccentric 21 which can be pivoted between the two positions shown in FIGS. 1 and 3 by means of an adjusting lever 22 accessible from the outside, the toothed rack 19 can be moved in the transverse direction in order to disengage the saw toothing 18 from the saw toothing 17 of the feed body 16 bring to.
- This shown in Fig. 3 Position is required so that the feed body 16 can be pushed back into its initial position when a new support rod 1 is inserted.
- the rack 19 is in drive connection with the slide 13.
- a pulling wire 23, a pulling strap or a similar pulling element is attached to the handle housing 4 at one end 23a.
- the pull wire 23 is guided around a roller 24 at the rear end of the rack 19 and from there to the slide 13.
- the front end 23b of the puller wire 23 is not firmly connected to the slide 13, but is only taken along by a stop 25 attached to the slide 13 when the slide 13 is at a predetermined distance from its front end position shown in FIG. 2 , which is limited by a stop surface 26.
- the driving stroke of the slide 13 for the puller wire 23 is precisely specified. This stroke length is approximately equal to twice the width of the marking rings 2.
- the rack 19 executes a forward movement with each complete movement stroke of the slide 13 in the handle housing 4, whose stroke is equal to the width of a marking ring 2. In this way, the feed body 16 is moved forward by the width of a marking ring 2 and brings the next marking ring 2 into the access area of the pawl claw 15.
- Fig. 3 shows the position before inserting a new support rod 1.
- the feed body 16 is in its foremost position; However, the rack 19 is raised by the eccentric 21 by actuating the actuating lever 22, so that the saw teeth 17 and 18 are disengaged.
- the anchoring slide 8 is pressed inwards. In this position, a new support rod equipped with marking rings 2 can be inserted through the transfer opening 6, whereby it pushes the feed body 16 into its rear starting position.
- the rear end 1b of the support rod 1 is inserted through the wider part of the opening 11.
- the anchoring slide 8 is released so that it overlaps and anchors the support rod 1 in the region of the lateral recesses 12 in the manner shown in FIG. 5.
- the eccentric 21 is turned over so that the saw teeth 17 and 18 engage. All parts of the hand-held device then assume the starting position shown in FIG. 1.
- the marking device 100 shown in FIG. 7 is intended for use in a hand-held device according to FIGS. 1-6 and has a supporting rod 1 made of plastic, on which a plurality of marking rings 2 slotted on the underside are seated, each bearing marking symbols 101.
- a longitudinal web 102 is arranged on the underside of the support rod 1, which engages in the slots of the plastic rings 2 and holds them in the predetermined orientation on the support rod 1.
- the support rod 1 is expanded to a mounting shoe 1 a, which has a longitudinal recess 103 on its underside, which can be placed on a line wire 3 in the manner indicated in FIGS. 1 and 7.
- a constriction is provided near the rear end 1b of the support rod 1, which serves for the positive anchoring.
- the constriction is formed by two lateral notches 12 (FIG. 8), which are arranged on opposite sides of the support rod 1.
- these two lateral notches 12 In horizontal section (view according to FIG. 8), these two lateral notches 12 have an approximately semicircular rounded profile.
- FIG. 9 shows, in a representation corresponding to FIG. 8, a modified embodiment in which a notch 12 is provided only on one side of the support rod 1.
- the semicircular profile of the notch 12 according to FIG. 9 corresponds to the profile of the notch 12 according to FIG. 8; however, it could extend deeper into the support rod 1 from the side than is the case with the notch on both sides according to FIG. 8.
