Definitions

  • the invention relates to a lever lock for locking hinged side walls of commercial vehicles with a hand lever which is pivotally mounted on a base plate attached to the side wall and has a locking hook which engages in an eyelet provided on an adjacent side wall, and with locking means which in their Lock position prevent opening of the hand lever and allow opening of the hand lever in its unlocked position.
  • Lever locks of this type have been known in the trade and have been known for a long time. They have the purpose of locking the side walls delimiting a loading area of commercial vehicles against one another or against stanchions fixed to the chassis.
  • closures are designed and arranged such that the hand lever is oriented vertically downwards in its closed position and the angled end of the locking hook engages in an eyelet attached to the adjacent side wall.
  • the closure hook which passes through an eyelet has a hole at its free end in which a split pin connected with a chain is inserted.
  • the other end of the chain is attached to the side wall.
  • latching devices or locking devices are also used, which are arranged between the locking lever and the base plate on which the lever is pivotably mounted.
  • Such a device is described in German utility model DE-U-8105158. Locking or locking devices of this type, however, on the one hand impair the simple construction of the closures, and on the other hand question the operational reliability of the closures in rough driving conditions.
  • the invention has for its object to develop a lever lock of the generic type so that it has the simple, uncomplicated structure required for a mass product and ensures a reliably secured closed position and a pleasant opening.
  • a resilient locking member serving as locking means is arranged on the hand lever, which in its Locking position rests under resilient bias on the locking hook and is held in its unlocking position in its unlocking position by means of a catch device provided on the hand lever or on the base plate and that control means are provided on the base plate which, when the hand lever is pivoted into its open position, automatically lock the locking member to return to release its locking position from the safety gear.
  • the locking member consists of a bar spring or a leaf spring, which is attached to the hand lever and rests in the locking position with its free end on the locking hook under resilient bias and is held in the unlocking position in the catch device formed on the hand lever, and that Control means is designed as a control cam provided on the base plate in the path of movement of the locking member.
  • the catching device can be designed as a latching recess worked into the hand lever.
  • the locking member consists of a rod-shaped spring element which is fastened to the hand lever and rests in the locking position with the free end on the locking hook under resilient pretension and is held and displaceably guided in the unlocking position in the catch device provided on the base plate and in that the control means is designed as a recess or platform lying in the path of movement of the locking member.
  • this embodiment is designed such that the catching device is designed as a groove which is machined into the base plate and runs in the direction of movement of the free end of the locking member and which has the cutout for the passage of the free end of the locking member in the region of the horizontal center line of the base plate.
  • the lever lock according to the invention allows the hand lever to be opened easily by holding the locking member out of the locking area on the locking hook when it is opened and automatically returning to its locking position before the lock is closed. This ensures a reliable function of the lock and thus a secure locking of the side walls of a commercial vehicle.
  • the object is achieved in that a resilient locking member serving as a locking means is arranged on the hand lever, which rests in its locking position under spring tension on the locking hook and in its unlocking position under spring tension on a control means formed on the base plate, and that when the hand lever is pivoted into its open position, the locking member automatically returns to its locking position.
  • the locking member is designed as a spring which is fixed in the locking position and in the unlocking position
  • the control means consisting of an elevation extending into the movement path of the locking member, against which the free end of the locking member rests and when the hand lever is pivoted over it middle dead center position is controllable in such a way that it suddenly reaches its locking position
  • the locking element designed as a spring can essentially consist of one -shaped spring clip, the open ends of which each have a bend, which engage in staggered bores provided on the hand lever and are mounted.
  • the locking member By designing the locking member as a spring held stable in two end positions, a very simple construction of the closure is achieved, which has a high degree of operational reliability and service life.
  • a manufacturing advantage for the base plate produced as a forged component can be achieved by making the elevation to the horizontal center line of the base plate a mirror image. This enables both a left-hand and a right-hand stop of the closure using a single component.
  • the lever lock shown in the drawing consists of a base plate 11 with a bearing eye 12 for receiving a bearing axis 13.
  • the base plate 11 is fastened to a side wall of a commercial vehicle by means of screws.
  • the bearing pin 13 is riveted into the bearing eye 12 and provided with a rivet head 14 at its free end.
  • a hand lever 15 is pivotably mounted on the bearing journal 13, a disc spring being arranged between the hand lever and the rivet head 14 to compensate for play.
  • the closure is shown in its closed position, in which a locking hook 17 passes through an eyelet 18 attached to an adjacent side wall 16.
  • the eyelet 18 is formed on an eyelet plate 19 which is fastened to the side wall 16 by means of screws.
  • the eye plate 19 can be made as a forged part.
  • the bottom side of the eyelet plate 19 is provided in its Nile facing away from the eyelet with a flat elevation 20 which extends outside the side wall surround 21 and which corresponds in height to the side wall surround 21.
  • the eyelet plate 19 can rest snugly on the side wall and be reliably attached without touching the side wall edging and being forced into an inclined position.
  • the hand lever 15 is provided with a handle 22 which projects vertically downwards in the closed position of the closure.
  • a spring-elastic locking member 23 is provided as locking means, which is fastened in a pocket 24 provided on the hand lever 15.
  • the free end of the locking member 23 has a bend 25 which is supported in the closed position of the locking lever on the locking hook 17 and possibly also on the eyelet 18.
  • the locking member 23 is pivoted in the direction of the arrow B by means of thumb pressure until its turn 25 engages and is held in a locking recess 26 formed on the hand lever 15. Now the locking hook 17 and the eyelet 18 are freely movable against each other and the hand lever 15 can be pivoted into its open position.
  • the locking member 23 held in the locking recess 26 runs against a control cam 27 provided on the base plate and is moved out of the locking recess 26. Due to its resilient bias, the locking member 23 automatically rests on the locking hook 17.
  • the bend 25 of the locking member 23 runs over the eyelet 18 and arrives in the closed position of the hand lever 15 again under the eyelet 18 and locks the hand lever 15 in this way against unintentional opening during driving.
  • the lever lock shown in Figures 2 and 3 is constructed essentially the same as that described in Figure 1.
  • the latching device consists of a groove 28 which is worked into a bead 29 provided on the base plate 11.
  • the bead 29 is generally used to support the hand lever 15 and to relieve the lever bearing against the locking forces that occur.
  • the end face of the base plate 11 is designed in the direction of the groove as a run-on slope 32.
  • the groove opens approximately in the central region of the base plate 11 in a recess 30.
  • the locking member is pivoted in the direction of arrow B by means of thumb pressure until its end having the bend 25 engages and is held in the groove 28 via the run-up slope 32.
  • the locking member 23 with its bend 25 reaches the area of the recess 30 and leaves the groove 28 due to its resilient pretension and rests on the locking hook 17.
  • the locking member 23 with its bend 25 overflows the eyelet 18 and is supported in the locking position of the closure on the locking hook 17 and possibly on the underside of the eyelet 18.
  • the control cam 27 or the groove 28 are formed in mirror image on the base plate 11.
  • FIG. 1 A further embodiment of the groove 28 is shown in FIG.
  • the bottom of the groove 28 is designed to rise towards the center of the base plate 11, and it ends in a platform 31, from which the locking member 23 with its bend 25 is finally derived during the opening process of the hand lever 15 and comes to rest against the locking hook 17.
  • the locking member 23 ' is designed differently from the locking member described above and mounted on the hand lever 15'.
  • the remaining structure of the lever lock corresponds essentially to the embodiment shown in Figure 1.
  • the locking member 23 ' consists of a -shaped spring clip 35 with spring legs 33 of different lengths, the free ends of which have pins 34 that are bent toward one another.
  • the spring clip 35 is attached to the hand lever 15 'by engaging with its pin 34 in the hand lever 15' one above the other bores 36.
  • the spring clip 35 forms a spring which is stable on two sides, so that it rests on the one hand under spring tension on the locking hook 17 'or on the underside of the eyelet 18' and on the other hand by means of thumb pressure while overcoming a middle dead center position on the base plate 11 'provided bead 29' is brought to bear.
  • the bead 29 ' has a locking hook 17' facing concave surface 37 on which the spring clip 35 rests in the open position of the closure under resilient bias.
  • the spring clip 35 is thus applied to the surface 37 of the bead 29 'by means of thumb pressure, and the locking hook 17' is moved out of the eyelet 18 '.
  • the spring clip 35 slides along the surface 37 until the middle dead center position of the spring clip 35 is overcome and the same snaps back into its locking position, in which it rests on the locking hook 17'.
  • the spring clip 35 overflows the eyelet 18' and then arrives again at the locking hook 17 'or on the underside of the eyelet 18 in a locking manner.
