Klauenhaken für rundstahlketten

The Ertindung refers to a claw hook for round steel chains, with two in distance parallel to each other arranged, from shank part, sheet section and tine existing, back section connected hook extending over one itself only over a part of the Hakenhöhe, which forms depending upon its training a reciprocally open or closed bag for the admission of a track link of a chain strand lying transverse to the s hooks, whereby between tines and sheet section of the hooks a slot to would bring in and/or is intended parallel to the mounting plate, to the hooks of a running track link following to the transverselying track link downward, with escape-ends for through-holes in the upper ends of the shank parts to the admission of a pin as well as perpendicularly with one around one essentially to the hooks running axle (A) between Freigabeund of a RST locking position tiltable safety device piece for the hung up chain strand. Kurzgliedrige round steel chains cannot be hung up because of the small interior of the members at a sufficiently strong hook point. For this reason so-called claw hooks were built, which a track link to enclose partially from the outside and it at its outer circumference above all from downside to support. Such a claw hook is for example at-PS 288,793 the Anmelderin is too infers. Since with claw hooks with a discharge of the chain and Schüttelbewegungen of the chain arising at the same time is possible for notices of the chain from the hook, for possibilities was looked for to create a protection for the hung up chain. Such a claw hook with a safety device piece is to be taken for example at-PS 391,007 the Anmelderin, which corresponds to the kind initially specified in the sense of the generic term of the requirement 1. With this claw hook is intended as safety device piece at the two shank parts of linked swiveling handles. With other claw hooks safety device pieces for downward the track link following to the transverselying track link are intended, such a doppe armiger, tiltable lever with check nose (AT2s HP of 359,785) and/or the slot between the hooks of bridging transverse pins (AT-PS 352,486 the Anmelderin). A number of well-known solutions was not up to in practice occasionally arising large forces, like a countermove at the usually unloaded chain section, or the operation of the safety device piece is pedantic and/or it exists the danger to lose the safety device piece. 9o a task of the invention lies in the creation of a claw hook with safety device piece, which is characterised by a robust design also regarding the safety device piece. This task is solved on the basis of a claw hook of the kind initially specified according to invention thereby that the safety device piece is designed as read-basic, tiltable piece of hanging up of the claw hook, which is blockable between the shank parts around the pin tiltable stored and at least as in its locking position the lower parts of the piece of hanging up as nose-like check extension is trained, which is so convenient in the locking position above the bag that the hung up, transverselying track link is upward prevented from escaping from the bag, against what in its swivelled release position the transverselying track link can be taken out of the bag and/or used into these, and that the upper section of the piece of hanging up is furnished for the connection to a chain strand od.dgl. The conception completely new with a claw hook, the safety device piece as read-basic to train tiltable piece of hanging up leads to a particularly robust and safe bolting device of the hung up chain. The invention is equally with claw hooks with reciprocally closed bag (e.g. AT-PS 391,007) and with beidsettig open bag (e.g. AT-PS 288,793) applicably. 4s a particularly favourable execution of the invention is characterised by it that for the blocking of the piece of hanging up in its locking position a BIockierstück tiltable stored between the shank parts is arranged, the one a rest surface of the piece of hanging up assigned retaining surface as well as, approximately above the back section a lain protruding to the rear handles exhibits and against Kraft of a reset spring is to the rear tiltable, in order to bring the R8stffäche Hurler interference with in such a way the retaining surface. This training particularly makes one possible eirr [- actle operation with a hand and offers besides the advantage, since the hook during load automatically into the blocked and blocked position changes, so that Bed mungstt is impossible. Hiebei can be üig it zwackrn, if the Blockierstü.ck at its front one to the HaJtefläche following, downward aJofallende G [eitfläche possesses, which is assigned to 3ä.che in the release position one to the RA ss the piece of hanging up following, upward rising accumulating surface. In the sense of the security of a user it is recommendable, if the blocking piece lies in the outermost release position of the Aufhä.ngest cks between the accumulating surface and the upper edge of the Schlater, so that getting jammed of a finger between Auflauffl che and shoulder is impossible. If the upper section of the piece of hanging up a photograph fork with fiuchtenden cross holes, whose axle runs perpendicularly to the axle of the pin, arises a stable execution of the piece of hanging up possesses 2 RKs 397,988 B in the case of small expenditure for material and supplies. The invention including other advantages is more near described in the following on the basis a remark example, which is illustrated in the design. In this Fig show. 1 a claw hook after the invention in front view, Fig. 2 this claw hooks in partly cut side view, with the piece of hanging up in locking position and Fig. 3 an identical opinion, however with the piece of hanging up in release position. In accordance with the Fig. 1 to 3 exists a claw hook 1 after the invention of two parallel, in distance to each other arranged hook 2, which is connected by a back section 3. Each hook 2 possesses a shank part of 4, a sheet section 5 and a tine 6. The inner surfaces of the hooks 2 form a bag 7 for the admission of a track link 8 of a lower chain strand g lying transverse to the hooks 2, which is to be connected by means of the claw hook 1 with an upper chain strand 10. To in the bag 7 of the claw hook 1 lying Kettengtied 8 of the lower chain strand 10 attaches downward a track link 11, which lies parallel to the hooks 2 and is held partially in a slot 12 remaining between the hook 2. The lower chain strand 9 can end above with the member 8, or still further members can upward attach, like the member 13 in accordance with Fig. 2. It is pointed out that the bag 7 is closed in the available case laterally, however laterally partly also openly to be again can, if the two hooks 2 do not possess lateral cheeks or partly broke through such cheeks. The shank parts of 4 are at their upper end with escape-end through-holes 14 for the admission of a pin 15 provided, on which a piece of hanging up of 16 between the shank parts 4 around the axle A of the pin 15 is tiltable stored. The piece of hanging up of 16 serves as read-basic safety device piece and possesses as nose-like check extension 17 trained lower part as well as on its upper section a photograph fork 18 with escape-ends cross holes 19, into which a load pin 20 can be inserted, in order to be able to connect the claw hook 1 with the lowest member of the upper chain strand 10. The axle b of the load pin runs to the axle A of the pin so the piece of hanging up of 16 is perpendicular around the axle A between a locking position (Fig. 1, 2) and a release position (Fig. 3) tiltable. In the locking position (Fig. the check extension 17 is in such a way been appropriate for 1, 2) above the bag 7 that the hung up, transverselying track link 8 is prevented from escaping from the bag. The Kettenglie0 8 pushes, if a course were e.g. made upward by the track link 13, above at the lower edge of the check extension 17 on. Of course the distance is so small between the upper a5 ends of the tines 6 and the lower edge of the check extension 17 in the locking position that the track link 8, even if it tilted forward as in Fig. 2 shown, still at the lower edge of the check extension 17 knocks against and thus one holds back. The piece of hanging up of 16 must be blockable - anyhow in its locking position -. A preferential execution of such a blocking is here shown. Between the shank parts of 4 one is parallel to the pin 15 running, reciprocally into the shank parts of 4 assigned pin 21 or a case a blocking piece of 22 tiltable stored and by means of an only suggested feather/spring 23 in the sense of a movement forward, i.e. in Fig by means of. 2 and 3 in the clockwise direction, preloads. The blocking piece of 22 possesses a retaining surface 24, which is assigned in the locking position to a rest surface 25 of the piece of hanging up of 16. At the blocking piece 22 is further approximately above the back section 3 one handles 26, similarly the piece of thumb of the departure hook of a handgun, trained, so that an operator by means of a thumb the blocking piece of 22 to the rear, in Fig. 3 position shown swivel can. In this position the piece of hanging up of 16 can be swivelled also to the rear, whereby against the retaining surface 24 following, downward sloping sliding surface 27 of the blocking piece of 22 an accumulating surface 28 downward sloping at the piece of hanging up of 16 rests. In this film order (Fig. 3) can be taken the transverselying track link 8 of the bag 7 and urtt from the RH chain course 9 from the claw hook 1 solved - or ° in these be used in reverse. A special advantage of the blocking of the piece of hanging up of 16 implemented here is then that with the occurrence of a 7_ugbelastung between the two chaining watering gene is moved automatically g and 10 the piece of hanging up of t6 into its locking position, whereby the retaining surface 24 slides. the blocking piece of 22 along the sliding surface 27 of the Aufhänge8tückes 16 to it into the position. opposite its Rastfiäche engages, so that the protection of the track link 8 takes place automatically, without effort of the operator. RK 397,988 B when opening the piece of hanging up of 16 supports the blocking piece of 22, which comes on the upper edge of the back 3 to the plant, the piece of hanging up 16 off, so that getting jammed the thumb between back 3 and piece of hanging up of 16 is e.g. prevented. It is marked in the long run that the terms used here refer “above” and “down” to the use of the claw hook in a vertical chain strand, but is clear it that the claw hook is usable just as e.g. in a horizontal chain strand. Also it is pointed out that the training of the upper end of the piece of hanging up is 16 as photograph fork 18 only one example of a connection type. The upper end of the piece of hanging up of 16 could be provided with a load eye for example also.
