Definitions

  • the invention relates to a locking device, in particular for motor vehicle door hinges, with two parts which are connected to one another in an articulated manner and which form a kinematic pair, the first part having a cam track with at least one catch, in which a spring guide is preloaded in the direction of the cam track, in a positive guide track Guide element is slidably guided locking element for the purpose of releasable locking of the second part.
  • Locking devices are known, in particular for motor vehicle door hinges, which represent a type of coupling which is installed together or independently of the door hinges.
  • the first part is equipped with a roller on an axis that rolls along a runway with notches in the second part. If the roller is in a rest position, the two articulated parts are locked.
  • the roller has a large diameter, which cannot be made small due to the existing axis. This requires a long spring travel and a large spring force. In most cases, the spring is a large torsion and bending element. It plays an active role and transmits the entire braking load and must therefore have a corresponding strength.
  • a door stay which has a large dimension bar spring.
  • the large-sized rod spring deforms under a forced movement over a runway, the catches of which form two rollers on the axles and a braking effect of the two articulated parts can occur.
  • the known door arrester has many individual parts, is comparatively incompatible and requires a large amount of spring pressure. The lock is subject to comparatively great wear.
  • the object of the invention is to provide a locking device of the type mentioned, which essentially eliminates the aforementioned disadvantages and, in particular, creates a locking device which, with reliable operation and with little wear and tear, is constructed very compactly from a few parts.
  • the essence of the invention is that the locking element in the form of a bolt or a roller is rotatably mounted in a concave slide bearing of the guide element.
  • a locking device of the type mentioned is known from EP-A-0 255 879.
  • this device has locking elements which are firmly attached to the guide elements or locking strips, in particular vulcanized.
  • the locking element according to the invention is rotatably mounted in the guide element, which the tangential locking forces on a larger area of the positive guide track transmits the second part, which is particularly low wear.
  • Rotatable locking elements are known in principle, for example from FR-A-2 645 900. However, these locking elements are not mounted in a concave slide bearing of a guide element.
  • a Locking element in particular a roller or a bolt, can be provided in a sliding manner in the slide bearing of the first part and roll over a roller or cam track with at least one catch in the guide element of the second part or rest in the catch, ie be locked.
  • roller or cam track of the first part has at least one rest with two additional adjacent rollers in the manner of the first-mentioned rollers, which slide in corresponding recesses in the roller or cam track.
  • the guide element can be firmly attached to the spring and can be directly or indirectly engaged with the roller or cam track.
  • it can be a spring eye of the spring, which is circular, oval or can have a rectangular cross section.
  • a good locking fit of the locking element is given if this element is designed as a roller or bolt with a diameter which corresponds to the diameter of a concave, in cross section essentially semicircular catch in the roller or cam track.
  • the bolt or the roller have a comparatively long axial extent and are in particular provided with a small diameter.
  • the diameter of the roller or the bolt is approximately 5 mm and the length of the roller or the bolt shaft is approximately 40 mm.
  • the spring is preferably used as a tension or compression spring, not as a torsion or spiral spring as in the prior art, and only has the function of applying a compressive force essentially perpendicularly, ie normally in the direction of the roller or cam track.
  • the perpendicular braking or locking force is taken up by the guide element, which is guided in a positive guideway.
  • the spring is therefore only used as a pressure generator and is released from the effect of the braking load.
  • the spring is preferably made of a highly elastic material, in particular rubber. However, it can also consist of an elastomeric plastic material.
  • the invention thus creates a hold-open device which can be built much smaller and more compact than a door hold-open device according to the prior art. It has few individual parts and shows a stable locking hold during operation, whereby only a slight spring pressure is sufficient to set up this stable locking hold.
  • the bolt At its end facing away from the bolt head, the bolt can have a conical section, the base diameter of which is larger than the diameter of the bolt shank.
  • the securing element is the larger base diameter of the tapered section, which serves as a bolt against pulling out the bolt.
  • Two parts which are connected to one another in an articulated manner can be pivotally connected or connected by means of a sliding joint or a link guide or another joint linkage. It is sufficient if they form a kinematic pair.
  • the roller or cam track can be circular, arbitrarily curved or also straight. It has one or more notches which are concavely arc-shaped and / or wedge-shaped in cross section.
  • the additional rollers according to claim 3 can right and left of the actual rest in the Roller or cam track may be provided.
  • a locking device in the form of a door lock in particular for a motor vehicle door hinge, is illustrated, which comprises two parts which are pivotally connected to one another and form a kinematic rotating pair.
  • the first part 1 has a roller or cam track 7 with two concave bulges, which are two notches 6.
  • the roller or cam track 7 is convexly curved around the center of the axis of rotation of the first part 1.
  • the second part 2 of the kinematic rotating pair which has the same center of rotation as the first part 1, has a positive guide track 8 in a recess open at the top of the second part, the recess running axially parallel to the axis of rotation of the kinematic pair 1, 2.
  • the positive guide track 8 has two lateral guide surfaces spaced apart from one another, which can be brought into an essentially play-free sliding engagement with lateral guide surfaces of an essentially cuboidal guide element 4.
  • the guide element 4 comprises along its entire longitudinal extent a concave slide bearing 9 and on the side facing away from the slide bearing 9 spaced apart transverse projections which can be brought into engagement with a substantially square mounting plate of a compression spring 3 in the assembled state of the arrangement.
  • the highly elastic member of the compression spring 3 has a circular cross-section, as can be seen in particular in the exploded drawing according to FIG.
  • the slide bearing 9 is in the assembled state of the arrangement in a circumferential engagement with a locking element in the form of a bolt 5, the length of the bolt shaft corresponding to the length of the slide bearing 9 or the guide element 4.
  • the bolt 5 has on its side facing away from the bolt head a conical section, the base diameter of which is slightly larger than the diameter of the bolt shank.
  • the two concave notches 6 are also shaped in accordance with the diameter of the bolt shank, as can best be seen in FIG. 4.
  • the guide element 4 is inserted from above into the recess of the second part 2 and the compression spring 3 from the side according to the direction of the arrow in FIG. 3 and brought into positive engagement with one another in the recess, the retaining plate of the compression spring 3 being spaced apart from one another transverse projections of the Interactively guide elements interact.
  • the pin 5 is inserted with its conical tip from above into the slide bearing 9 against the force of the compression spring 3. If the cone tip of the pin 5 reaches the other free end of the slide bearing, the slide bearing 9 snaps in along the entire pin shaft.
  • Both swivel parts, first part 1 and second part 2 can thus be swiveled so that, when swiveled, the assembled bolt 5 rolls along the roller or cam track 7 of the first part 1 and slides along the slide bearing 9. In the course of its rolling movement of the bolt 5, it also reaches the two locking positions along the rolling or cam track 7, which are predetermined by the two concave catches 6 in the rolling or cam track 7 of the first part 1.
  • roller or bolt 5 can also be brought into engagement and locked with the actual roller or cam track 7 via an intermediate member.
  • the first part 1 and second part 2 of the locking device remain mutually locked as long as the intended external braking load in the form of the torque M according to FIG. 4 is not exceeded. If the braking torque M is exceeded, the two parts 1 and 2 begin to move relative to one another. Guide element 4 moves in the positive guide track 8 against the force of the compression spring 3, and the roller or the pin 5 slides in the slide bearing 9 and rolls along the roller or cam track 7 to the next rest 6.
  • the positive guidance path 8 takes over the entire braking load P n , while that which is only claimed under pressure Spring 3 is released from the braking load.
  • both parts 1 and 2 can be firmly held, ie locked, with the aid of simple means. Few individual parts are required for this.
  • the overall arrangement is comparatively small. Together with a small diameter of the roller or bolt 5, the sliding and rolling surface of which is the same, the use of a relatively small spring 3 is possible.
  • the decisive factor is the pressure angle ⁇ . The larger ⁇ (up to a maximum of approx. 80 °), the more favorable the transmission ratio P n / P r , ie the smaller the spring force P r in order to generate a necessary braking force P n .
  • the exemplary embodiment of another door arrester illustrated in FIG. 5 basically corresponds to that according to FIGS. 1 to 4.
  • the kinematic pair consisting of the first part 1 and the second part 2 is not designed as a swivel joint, but as a sliding joint.
  • the first part 1 has an elongated hole guide in which two spaced-apart transverse pins of the second part 2 are received. The distance between the two cross pins corresponds to half the length of the slot guide.
  • the first part 1 is displaceably guided relative to part 2.
  • a roller or cam track 7 is also provided which, in contrast to the exemplary embodiment according to FIGS. 1-4, runs essentially in a straight line outside the two catches 6.
  • the braking torque M according to the door arrester according to FIGS. 1 to 4 is to be equated here with the braking force F, which is in the direction of the roller or cam track or the displacement movement works. If the braking force F is exceeded, both parts 1 and 2 move relative to each other. In a corresponding manner, the guide element 4 also moves here in the positive guide track 8 against the force of the compression spring 3, and the bolt 5 slides in the slide bearing 9 and rolls over the roller or cam track 7 to the next rest 6. Here too, the positive guide track takes over 8 the total braking load.
