Opfindelsen angår et anhængertræktøj, især til personautomobiler, og bestående af en på køretøjets bagende fast anbragt optagelsesdel med en skråt bagud og nedad rettet rørstuds, der. har på hver sin side af denne anbragte holdelasker, og af en ved sin ene 5 ende med en koblingskugle forsynet kuglehals, der med et kugleformet område ved sin anden ende er stukket ind i rørstudsen og i afstand fra denne er løsbart fastgjort til holdelaskerne.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a towing tool, in particular for passenger cars, and comprising a mounting portion fixed to the rear of the vehicle with a sloping rearward and downwardly directed pipe butt which. has on each side of this holding lugs, and of a ball neck provided at one end with a coupling ball, which with a spherical region at its other end is inserted into the pipe nozzle and at a distance from it is detachably attached to the holding lugs.

Fra beskrivelsen til tysk patentansøgning P 34 23 730 kendes et anhængertræktøj af denne art, ved hvilket kuglehalsen ved 10 hjælp af en skrue er fastgjort løsbart til holdelaskerne i afstand fra kuglehalsens indstiksende. Skønt denne fastgørelse opfylder alle krav, ønsker mange brugere af anhængertræktøj et anhængertræktøj, ved hvilket kuglehalsen med koblingskuglen med få håndgreb kan henholdsvis indsættes i og udtages af optagelsesdelen, uden at der 15 hertil skal anvendes værktøj, og uden at der efter at kuglehalsen med koblingskuglen er løsnet skal opbevares separate dele foruden kuglehalsen.From the specification of German patent application P 34 23 730 there is known a towing tool of this kind, in which the ball neck is fixed releasably by means of a screw to the holding lugs at a distance from the ball neck insertion. Although this attachment meets all requirements, many users of towing tools want to use a towing tool by which the ball handle with the coupling ball with few handles can respectively be inserted into and removed by the attachment part without the use of tools and without the ball neck with the coupling ball are detached must be kept separate parts besides the ball neck.

Formålet med opfindelsen er derfor at tilvejebringe et anhængertræktøj, ved hvilket alle låse- henholdsvis frigørelsesdele 20 forbliver siddende på kuglehalsen, efter at kuglehalsen med koblingskuglen er udtaget af optagelsesdelen.The object of the invention is therefore to provide a towing tool in which all locking and release parts 20 remain seated on the ball neck after the ball neck with the coupling ball is removed from the receiving part.

Denne opgave løses ifølge opfindelsen ved, at holdelaskerne er forbundne med hinanden ved hjælp af en vandret bærebolt, at kuglehalsen har et optagelsesorgan med to på hver sin side af kugle-25 halsen beliggende opad åbne kroge til indgreb med bærebolten, og at der på optagelsesorganet er anbragt låsebolte, der lukker krogene, og under fjederbelastning ligger, an med en kileflade mod bærebolten og kan betjenes samtidigt med hinanden.This task is solved according to the invention in that the holding lugs are connected to one another by means of a horizontal support bolt, that the ball neck has a receiving means with two upwardly open hooks for engaging the support bolt and that on the receiving means is provided with locking bolts that close the hooks and under spring load, with a wedge surface against the support bolt and can be operated simultaneously with each other.

De med kuglehalsen fast forbundne kroge griber ved ind-30 sætningen af kuglehalsen i optagelsesdelen hurtigt og sikkert nedefra rundt om bærebolten, når låseboltene er trukket tilbage, og efter frigivelsen af låseboltene sammenlåses kuglehalsen automatisk med holdelaskerne. Det er endvidere særligt fordelagtigt, at der opnås en slørfri sammenspænding og i tilfælde af slid en permanent justering af 35 sammenspændingen.The hooks attached to the ball neck, when inserting the ball neck into the pick-up section, quickly and securely engage from below the support bolt when the locking bolts are retracted, and after the release of the locking bolts, the ball neck is automatically locked with the holding lugs. Furthermore, it is particularly advantageous to achieve a veil-free tension and in the event of wear a permanent adjustment of the tension.

De to låsebolte kan fordelagtigt være forbundne med hinanden ved hjælp af et bøjlehåndtag, således at en samtidig betjening af begge låseboltene er mulig.Advantageously, the two locking bolts may be connected to each other by means of a hanger handle, so that simultaneous operation of both locking bolts is possible.

armfjeder, der er lejret pi optagelsesorganet, og indgriber i en boring i låsebolten. Til det samme formål kan der også i stedet for armfjedre anvendes skruefjedre.arm springs mounted in the retaining means and engaging in a bore in the locking bolt. For the same purpose, screw springs can also be used instead of arm springs.

Til fastholdelse af kuglehalsen i en centreret stilling kan 5 bærebolten have et centreringsorgan til anlæg mod kuglehalsen henholdsvis optagelsesorganet.For holding the ball neck in a centered position, the carrier bolt may have a centering means for abutting the ball neck and the receiving means, respectively.

Yderligere fordelagtige udformninger fremgår af den følgende beskrivelse og tegningen, hvor fig. 1 viser et sidebillede af anhængertræktøjet ifølge 10 opfindelsen og fig. 2 viser et billede af denne set i pilretningen li i fig. 1.Further advantageous embodiments will be apparent from the following description and the drawing, in which fig. 1 shows a side view of the trailer tool according to the invention and FIG. 2 shows a view of this seen in the arrow direction 1i in FIG. First

Ved den bageste ende af et personautomobil er der under karrosseriets bageste skørtdel er der som optagelsesdel for et anhæn-15 gertræktøj fastgjort en tværdrager, der ved midten har en skråt nedadrettet rørstuds 2, og på hver sin side af denne anbragte holdelasker 3. De frie ender af holdelaskerne 3 er fast forbundne med hinanden ved hjælp af en vandret bærebolt 4. Kuglehalsen 5 med koblingskuglen 6 er i det område, hvormed den indføres i rørstudsen 20 2, forsynet med en del kugleformet ansats 7. Kuglehalsen 5 har endvi dere et optagelsesorgan 8, der er forsynet med to på hver sin side af kuglehalsen anbragte kroge 9, der er åbne i retningen opad. Krogene 9 lukkes ved hjælp af låsebolte 11, der føres i boringer 10, og er forsynede med kileflader og fjederbelastes af de frie ender 13 af 25 armfjedre 14, der er lejrede på optagelsesorganet 8. Hertil griber den frie ende 13 af fjederarmen ind i en boring i den pågældende låsebolt.At the rear end of a passenger car, underneath the rear skirt portion of the body, a transverse carrier is attached, which has at its center a sloping downward-facing pipe support 2, and on each side of this holding brackets 3. ends of the holding lugs 3 are firmly connected to each other by means of a horizontal support bolt 4. The ball neck 5 with the coupling ball 6 is provided in the area with which it is inserted into the pipe nozzle 20 2, with some spherical shoulder 7. The ball neck 5 also has a receiving means. 8, provided with two hooks 9 on each side of the ball neck, open in the upward direction. The hooks 9 are closed by means of locking bolts 11 inserted in bores 10 and provided with wedge faces and spring loaded by the free ends 13 of 25 arm springs 14 mounted on the receiving member 8. To this, the free end 13 of the spring arm engages in a drilling into that locking bolt.

De to låsebolte 11 er forbundne-med hinanden ved hjælp af et bøjlehåndtag 15.The two locking bolts 11 are connected to each other by means of a hanger handle 15.

Når kuglehalsen 5 med koblingskuglen 6 er indsat i den fast 30 med køretøjet forbundne optagelsesdel indtager alle anhængertræktøjets dele den på tegningen viste stilling. Den del kugleformede ansats 7 på kuglehalsen er optaget i rørstudsen 2. Krogene 9 griber nedefra om bærebolten 4. Låseboltene 11's kileflader 12 ligger an mod bærebolten 4. På grund af den konstante fjederbelastning, som arm-35 fjedrene 14 udøver på låseboltene 11, kan der ikke optræde et spille rum mellem bærebolten 4 og krogene 9. Derved udlignes også eventuelt slid af delene. En fastholdelse af kuglehalsen i en midterstilling opnås ved hjælp af et med bærebolten 4 fast forbundet centreringsorgan 16.When the ball neck 5 with the coupling ball 6 is inserted into the fixed part 30 connected to the vehicle, all the parts of the trailer tool occupy the position shown in the drawing. The portion of spherical shoulder 7 on the ball neck is accommodated in the tube 2. The hooks 9 engage from below the support bolt 4. The wedge faces 12 of the locking bolts 11 abut the support bolt 4. Due to the constant spring load exerted by the arm-springs 14 on the locking bolts 11, there is no play space between the support bolt 4 and the hooks 9. This also compensates for possible wear of the parts. A retaining of the ball neck in a center position is achieved by means of a centering means 16 fixed to the support bolt 4.

Ved aftagning af kuglehalsen 5 trækkes bøjlehåndtaget 15 i pilretningen 17 mod armfjedrene 14‘s virkning. Derved trækkes liseboltene 11 si langt tilbage, at kuglehalsen 5 kan frigøres fra bærebolten 4 og trækkes ud af rørstudsen 2. Alle Ilse- henholdsvis sam-5 menspændingsdele forbliver herunder siddende pi kuglehalsen.When the ball neck 5 is removed, the handle 15 is pulled in the direction of arrow 17 against the action of the arm springs 14. Thereby, the ratchet bolts 11 are pulled back far enough that the ball neck 5 can be released from the carrier bolt 4 and pulled out of the pipe nozzle 2. All Ilse and compression-clamping parts, respectively, remain seated in the ball neck.

Ved fastgørelse af kuglehalsen 5 trækkes bøjlehåndtaget 15 tilbage, og kuglehalsen stikkes ind i rørstudsen 2, hvorved krogene 9 nedefra føres op til anlæg mod bærebolten 4. Ved frigivelsen af bøjlehåndtaget 15 sker der automatisk en sikker fastlåsning af kugle-10 halsen.When fastening the ball neck 5, the shackle handle 15 is retracted and the ball neck is inserted into the pipe nozzle 2, whereby the hooks 9 from below are brought up to abutment against the support bolt 4. When the shackle handle 15 is released, a secure locking of the ball-10 neck is automatically made.

Bøjlehandtaget 15 er hængslet på låseboltene 11 på en sådan måde, at låseboltene hver for sig kan overtage lisefunktionen.The hanger handle 15 is hinged on the locking bolts 11 in such a way that the locking bolts can take over the latching function separately.

Eventuelt kan optagelsesorganet 8 være udformet på en sådan måde, at krogene 9 ovenfra griber om bærebolten 4. Krogene 9 15 kan også i stedet for at være anbragt neden under kuglehalsen være anbragt oven på denne.Optionally, the receiving member 8 may be formed in such a way that the hooks 9 from above engage the support bolt 4. The hooks 9 15 may also be placed on top of this instead of being located below the ball neck.

Som en ekstra sikring for låseboltene kan der anvendes fjedersplitter eller fjederpåvirkede sikringsstifter.As an additional fuse for the locking bolts, spring splits or spring-influenced fuse pins can be used.
