Definitions
- Locking device in particular for motor vehicle door hinges
- the invention relates to a locking device, in particular for motor vehicle door hinges, with two articulated parts which form a kinematic pair.
- 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 runs along one axis
- the roller has a large diameter, which cannot be made small due to the existing axis.
- the object of the invention is to provide a locking device of the type mentioned at the outset, which substantially eliminates the aforementioned disadvantages and, in particular, creates a locking device which operates reliably. is constructed very compact with little wear from a few parts.
- the first part has a roller or cam track with at least one catch and the second part has at least one positive guide track, along which a guide element moves during operation and under the pressure of a spring as a bolt itself or by means of a slide bearing locking element of the guide element, in particular a roller or a bolt, can be brought directly or indirectly into engagement with the roller or cam track and can be locked in the detent.
- a Locking element in particular a roller or a bolt, can be provided in a sliding bearing in 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 of the type 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 engaged directly or indirectly 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 provided if this element is designed as a roller or bolt with a diameter which corresponds to the diameter of a concave, essentially semicircular cross section 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 bolt is approximately 5 mm and the length of the roller or 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 pressure craft essentially vertically, ie normally in the direction of the roller or cam track.
- the perpendicular braking or locking force is received by the guide element, which is guided in a forced guide track.
- 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 therefore creates a hold-open device which can be constructed 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, only a slight spring pressure being 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 whose base diameter is larger than the diameter of the bolt shank.
- the securing element here is the larger base diameter of the cone section, which serves as a bolt to prevent the bolt from being pulled out.
- 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.
- 1 is a locking device of a motor vehicle door in a perspective view
- FIG. 2 is a partially cut door lock according to FIG. 1 in a different pivot position
- FIG. 3 shows the door arrester according to FIGS. 1 and 2 in an exploded perspective view
- Fig. 4 shows the door arrester according to Fig. 2 in a schematic plan view, neglecting the frictional forces
- Fig. 5 is a plan view of an alternative configuration door lock.
- FIG. 1 to 4 illustrate a locking device in the form of a door lock, in particular for a motor vehicle door hinge, which comprises two parts which are pivotally connected to one another and which 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 guideway 8 has two lateral guide surfaces spaced apart from one another, which can be brought into a substantially play-free displacement 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 projections which in the assembled state of the arrangement can be brought into engagement with an essentially square fastening plate of a compression spring 3.
- 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 engagement with one another in the recess, the holding plate of the compression spring 3 being spaced apart from one another transverse projections of the Interactively guide elements interact.
- the bolt 5 is pushed 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 bolt 5 reaches the other free end of the slide bearing, the slide bearing 9 engages along the entire bolt shaft.
- Both swivel parts, first part 1 and second part 2 can thus be swiveled such 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 the 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 forced guide path 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 path 7 to the next rest 6.
- the positive guideway 8 takes over the entire braking load P, while the only applied under pressure said 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. Along with a small diameter the
- 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 rather 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 transverse 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 force M which is equal to the braking torque M according to the door arrester according to FIGS. 1 to 4, which is in the direction of the roller or cam track or the displacement movement works. If the braking force F is exceeded, the two parts 1 and 2 move relative to one another. 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 until the next rest 6. Also takes over here the positive guideway 8 the total braking load.
