Definitions

  • the invention relates to a lock for a hood of motor vehicles, in particular of trucks, with a fixed to the chassis of the motor vehicle and a locking device for a fixed to the hood latch bolt lock box, wherein the lock case has a slot for the passage of the locking bolt and the locking bolt on a mounted on the hood locking pin holder is held.
  • a hood lock with the aforementioned features is from the US 2,830,836 A known.
  • the lock case fastened to the vehicle chassis has an opening for the passage of the locking bolt attached to the hood, this results in the problem that due to the tolerances unavoidable especially on the large body parts of trucks precise alignment of locking bolts and associated opening in the lock box must be made to each other to ensure the smoothest possible repeatability of Closing and opening operations is ensured with an entry or a sliding out of the locking bolt in or out of the opening of the lock case.
  • the extent necessary alignment of lock case and locking pin to each other is not only difficult to accomplish in the assembly of the lock on the motor vehicle, but also in the implementation of time consuming.
  • a tilt plate lock is known as a boot lock in motor vehicles, in which a locking pin can be advanced through an opening in a lock plate and the plate can be tilted so that it clamps with the locking pin and receives grip on this to hold the lock in a closed state.
  • both the lock case and the locking pin with respect to the body parts carrying them are movable, ie slidably disposed.
  • the invention is therefore the object of a hood lock with the features mentioned in such a way that its initial assembly is made easier on the motor vehicle.
  • the invention provides in its basic idea that the locking bolt for its initial locking with the lock case is slidably fixed against the action of a locking bolt against the latch bolt holder spring element in an orthogonal to the slot of the lock housing fixed to the chassis lock bolt holder aligned in the slot Connection to the first-time locking with the lock case in its by the engagement of the locking bolt in the slot of the lock case automatically aligned to immovably fastened lock case and fixed by the action of the spring element position by means of a displaceably arranged on the locking bolt lock nut is permanently fixed to the locking pin holder.
  • the locking bolt automatically aligns in its subsequent smooth locking and unlocking effecting position when it is first locked to the lock case by snapping into the aligned on the lock box slot.
  • the locking pin when first collapsing in the lock case in the other axis in the latch pin holder formed slot so move that he specified in the formed by the slot in the lock box Escape is positioned.
  • the locking pin is fixed by the action of him biasing against the locking pin holder spring element and is determined after unlocking and free coming from the lock case overcoming its resilient bias against the locking pin holder on the locking pin holder permanently.
  • a repeatability of the locking and unlocking movements is ensured.
  • the locking pin holder facing the end of the locking bolt engages through the slot formed in the locking pin holder and is mounted in a sliding on the locking pin side of the locking pin holder sliding nut.
  • the spring element is formed as between a displaceably arranged on the locking bolt lock nut and the locking pin holder supporting spring washer.
  • the spring washer must apply such a bias that the locking pin can align on the one hand when first collapsing in the slot of the lock case by a movement of the sliding block in Rastbolzenhalter, but on the other hand, the spring element the locking pin in the aligned position when unlocking the lock and free coming Locking bolt must keep fixed from the slot in the lock case until the locking pin is fixed to the locking pin holder by tightening the lock nut, whereby the effect of the Fedetiatas is overridden by tightening the lock nut.
  • pot supporting pressure spring is arranged, wherein the pot when pressing the locking bolt in the slot of the lock box by its support on the surface of the lock box is moved while tensioning the compression spring.
  • the tensioned compression spring ensures that the locking pin is released automatically when unlocking the lock by the force of the relaxing compression spring from the slot in the lock case.
  • the lock according to the invention also comprises a locking device for the locking bolt
  • a locking device for the locking pin can be provided according to an embodiment of the invention, that on the locking pin holder facing away from the inside of the lock case arranged locking device for the locking pin consists of two against each other under spring action rotatably arranged bars, which the locking pin between enclose and engage in their spring-loaded locking position in a groove formed at the front end of the locking bolt and thereby set this on the lock case.
  • the lock 10 consists of a lock case 11 which is to be fastened with attachment wings 12 to a vehicle chassis, and from an associated locking pin holder 14 with a detent pin 16 disposed thereon, wherein the detent pin holder 14 to fasten by means provided in fastening lugs 15 holes on a hood is.
  • the lock case 11 For locking the locking bolt 16 in the lock case 11, the lock case 11 a aligned in a first direction slot 13, in which the locking pin 16 with a formed at its front end, conically narrowing tip 17 can occur.
  • the locking pin 16 has a circumferential groove 18, which comes to lie behind the associated wall of the lock case 11 with latch bolt 16 locked with the lock case 11 and there by a later ( FIG. 5 ) is defined to be described locking device.
  • a lock nut 20 is disposed on the locking pin 16, which is displaceable due to a correspondingly provided thread by rotation on the locking pin 16.
  • the locking pin 16 passes through with its other, the conical tip 17 facing away from the locking pin holder 14 in a slot 23 which is aligned orthogonal to the arranged in the lock box 11 slot 13.
  • a sliding block 24 is slidably disposed on the surface of the locking pin holder 14, with which the associated and the slot 23 by cross-end of the locking bolt 16 is firmly connected.
  • a spring washer associated washer spring element 19 is arranged, which is clamped between the lock nut 20 and the locking pin holder 14 and due to this bias the locking pin 16 in the slot 23 of the locking pin holder 14 sluggish keeps sliding.
  • a pot 22 is disposed on the locking pin 16, which serves as an abutment for a between the lock nut 20 and the pot 22 supporting the compression spring 21.
  • the pot 22 is in the off Figures 1 and 2 apparent starting position defined on the locking pin 16, but in the direction of the locking pin holder 14 to be displaced.
  • the locking of the locking bolt 16 with the lock box 11 ( FIGS. 3 and 4 ) provided locking device is as shown in FIG. 5 from two on the back of the lock case 11 by means of a rotary bearing 32 rotatably mounted bars 25, 26, wherein the bars 25, 26 are biased by a tension spring 27 in its locking position for the locking pin 16, in which the mutually facing locking edges 28 of the two bars 25th , 26 come to rest on passage of the locking bolt 16 through the slot 13 of the lock box 11 in the locking groove 18 of the locking bolt 16.
  • a stop hole 29 is formed on the latch 25 for engagement of an actuator for the locking device, which may be formed, for example, as a cable. Will be attached to the stop hole 29 cable in the illustration FIG. 5 pulled to the right, this leads to a pivoting of the bolt 25 in the counterclockwise direction about the pivot bearing 32.
  • the Ferderelement 19 holds the locking pin 16 in its fixed position in the slot 23 of the locking pin holder 14, so that subsequently by tightening the lock nut 20, the effect of the spring element 19th canceled and the locking pin 16 is permanently fixed in the pre-fixed position on the locking pin holder 14. This ensures a smooth locking and unlocking later.
  • the unlocking of the lock is supported by the tensioned by the pot 22 during compression spring 21, which seeks to relax and therefore after release of the locking bolt by the latch 25 and 26 causes an automatic sliding out of the locking bolt 16 from the slot 13 of the lock box 11 ,
