Definitions

  • the present invention relates to an automatic coupling assembly according to the preamble of claim 1. Many possible mechanisms exist for coupling a pin in a socket.
  • These cams are generally positioned in the edge of the other part by means of a(n) (auxiliary) mechanism.
  • a number of these mechanisms make it possible to couple the two parts (fully) automatically.
  • a more specific embodiment of this is a rotationally symmetrical coupling pin which is moved into a counter coupling part (socket), and wherein one or more cams engage in the recessed edge of the coupling part. Owing to the rotationally symmetrical shape, a correct mutual rotation position is no longer important. It is also possible to rotate the two parts relative to each other after the connection has been made.
  • a further specific embodiment involves making the run-in end of the pin and/or the run-in end of the cams a conical shape, which simplifies the positioning of the two parts relative to each other.
  • the conical shape of the pin or cams can also be used to push the cams aside.
  • the cams subsequently move back (close), and at the locking side the cams engage in the recessed edge of the coupling pin.
  • the cams form only part of the 360-degree support around the edge of the rotationally symmetrical coupling pin.
  • This embodiment can vary between one cam and many cams, with slight support to almost full support all the way round.
  • a rotationally symmetrical conical shape of the run-in part of pin and/or cams in the case of two cams cannot push the latter aside, unless said cams are supporting only a limited part of the edge.
  • a commonly used embodiment involves only a support of roughly 90 degrees per cam. These 90 degrees are selected in such a way that if the semicircular arc of each cam is defined from 0 to 180 degrees, the 90- degree contact face runs from 45 to 135 degrees.
  • the object of the present invention is to provide an improved coupling assembly which does not have the disadvantages described above; in other words, a coupling assembly provided with only two cams, a full 360-degree support by the cams around the edge of the coupling pin, and an automatic outward movement of said two cams during the run-in of the pin.
  • the rotationally symmetrical pin or coupling part can comprise all constructions of a recessed edge or locking part known in the prior art for making a connection with the locking cams. It should also be understood that this recessed edge can comprise many shape variations. The conical shape can likewise comprise many shape variations.
  • the counter coupling part or socket part can comprise all constructions and shapes known in the prior art for positioning the conical shape of the coupling part or pin.
  • the counter coupling part can also comprise all constructions known in the prior art for supporting two locking cams at the position of the corresponding edge in the coupling part.
  • the counter coupling part guides both locking cams, so that, through the conical shape of the coupling part, the locking cams are guided aside and are guided back again into the recessed edge of the coupling part.
  • This guide can comprise all constructions known in the prior art.
  • the two locking cams can comprise all constructions known in the prior art for locking at the one locking side and for pushmg apart at the other side.
  • each cam forms a 180-degree semicircular support
  • the other guiding side forms a support that is such that if the semicircular arc of each cam is defined from 0 to 180 degrees, an approximately 90-degree circular arc runs from 45 to 135 degrees.
  • the guiding side forms an increasing radius, measured from the axis of rotational symmetry of the coupling part, from 45 to 0 degrees and from 135 to 180 degrees.
  • the conical part continuously supplies a force for pushing the cams aside with increasing cross sections of the conical part.
  • this increasing radius is formed by a linear curve (straight line), which simplifies production machining operations.
  • the angle of inclination of the conical shape of the coupling part is selected in such a way that said angle of inclination is greater than the angle between the guiding side and the locking side of the cams, such that the conical shape makes contact only with the contact face on the guiding side of the cams, and not on the locking side.
  • the resulting contact force that occurs on the guiding side has a component in the direction of movement of the cams and pushes the latter aside.
  • the conical shape is in the form of a linear curve (straight line), which simplifies production machining operations.
  • the conical shape of the counter coupling piece is matched to the conical shape of the coupling piece in such a way that the two parts are guided towards each other, and simple positioning between the two coupling parts is achieved.
  • a cable is connected smoothly to the conical shape of the rotationally symmetrical coupling part, and the counter coupling part is in the form of a hollow construction through which said cable can be drawn.
  • the rotationally symmetrical coupling part is automatically guided into the counter coupling part, in order to produce the coupling connection.
  • Figs. 1, 2 and 3 relate to illustrations of the prior art.
  • Fig. 4 and the further figures relate to the present invention.
  • Figs, la, lb and lc are illustrations of an automatic coupling mechanism with two cams and only partial support around it;
  • Figs. 2a - 2c show the coupling of the coupling mechanism in cross section at the position of the axis of symmetry parallel to the direction of sliding of the locking cams;
  • Figs. 3a - 3c show the coupling of the coupling mechanism in cross section at the position of the locking cams perpendicular to the axis of rotational symmetry
  • Figs. 4a - 4c show the different views and cross section of the locking cams of the present invention
  • Figs. 5a - 5c show the coupling of the coupling mechanism of the invention for the same position as that in Figs. 3a - 3c;
  • Figs. 6a - 6b are illustrations of an application of the coupling mechanism in a(n) (emergency) towing system for ships; and Fig. 7 shows in perspective a cam according to the invention.
  • Figs, la, lb and lc show diagrammatically the coupling mechanism according to the prior art, in the coupled position, in side view, top view and cross section respectively at the position of the locking cams.
  • the figures show the coupling part or coupling pin 1 with the locking part with the recessed edge 5 and run-in part with conical tip 6, and the line of rotational symmetry 9 and socket part or counter coupling part 2, the two locking cams 3 with only a partial support of the recessed edge, the. guide 4 of the locking cams, the conical guide of the counter coupling part 7 and the resilient auxiliary means 8 for pushing back the locking cams.
  • the cross section of Fig. lc clearly shows the shape of the locking cams 3 and the partial support (roughly 2 x 90 degrees) of edge 5 of the pin 1 in the position where the parts are brought together.
  • Figs. 3a - 3c show the same coupling as that in Figs. 2a — 2c, but in cross section at the position of the locking cams.
  • the contact surface between the conical tip and the locking cam is shown in Figs. 3a and 3b, resulting in two forces each below 45 degrees, indicated by arrows.
  • the partial support between the locking cams and the recessed edge can be seen clearly in Fig. 3c.
  • Fig. 4a shows the locking cam of the present invention viewed from the run-in side on the guiding side of the cam, between cross section A and B a 45-degree circular arc 16 with a radius rl being followed, and between cross section B and D a linear curve 17.
  • Fig. 4b shows the locking side of the same cam.
  • the various cross sections A-D are shown in Fig. 4c.
  • At C and D the conical tip is also shown, the angle of inclination of the conical tip being greater than the angle between the guiding side (on the right) and the locking side (on the left) of the cams.
  • Figs. 5 a and 5b show the contact surface between the conical tip and the locking cam on the guiding side, resulting in two forces, each below 45 degrees, indicated by arrows.
  • the locking side of the cams is shown by a dotted line. It can be seen in Fig. 5c that the cams offer a full 360 degrees of all-round support to the recessed edge.
  • Figs. 6a, 6b and 6c show the coupling mechanism according to the present invention in a towing system for ships in the coupled state, in side view and top view respectively.
  • the figures further show a cable 10, which is connected smoothly to the conical tip 6 and is guided through the hollow counter coupling piece 2.
  • the figures further show a round guide 11, which ensures good guidance of position and rotation of the coupling piece in the counter coupling piece.
  • Fig. 7 shows cam part 3 in perspective.
  • the curve from the locking side to the run-in side can be seen from this figure.
  • cam part 3 is purely a circular shape, while at the run-in side this same shape is present over a limited arc of approximately 90°.
  • the other part extends along a straight line.
  • the system can be used in many embodiments, varying from very small to very large structures. It must also be understood that this invention can be used in many heavily loaded metal coupling mechanisms. Examples are many coupling mechanisms in shipping, both between individual maritime objects and between maritime objects and the shore. In addition, there are applications for towing systems both for regular use and for use in emergency situations.

Abstract

L'invention concerne un agencement comprenant un élément de couplage symétrique sur le plan de la rotation, doté d'un embout conique et d'un bord évidé, ainsi qu'un élément de contre-couplage doté de deux cames de blocage (3). Etant donné la forme spécifique de ces deux éléments de couplage, lorsqu'on les déplace l'un vers l'autre, les cames de blocage sont repoussées de côté par l'embout conique de l'élément de couplage symétrique, puis sont remises en place ensemble à l'aide de moyens auxiliaires, pénétrant ainsi dans le bord évidé de l'élément de couplage. Ainsi, cet agencement permet d'obtenir 360 degrés de support de couplage, entre les deux éléments.
