Definitions
- the invention relates to a lock for a flap or a door having the features of the preamble of claim 1.
- the door or flap may be a door or flap of a motor vehicle or a building.
- the aforementioned lock comprises a locking mechanism with a rotary latch and at least one pawl, with which the catch can be locked in a closed position by locking surfaces of pawl and rotary latch.
- Detent surfaces means the surfaces of the rotary latch and pawl which abut each other for a locking of the locking mechanism and then have a Liberdeckung result.
- the rotary latch In a closed position, the rotary latch is able to hold a locking bolt of a door or a flap, so that the door or flap can not be opened. If the catch is in an open position, the locking bolt can leave the locking mechanism and the door or flap can be opened.
- flaps include tailgates for motor vehicles.
- an insert in, for example, a backrest of a motor vehicle seat is adjustable.
- a rotary latch has a load arm and a tentacle.
- the load arm prevents in the case of a locked locking mechanism immediately that a locking bolt a door or a flap can leave the locking mechanism. If a door or a flap is closed, the locking pin is moved against the catching arm and pivots it and thus also the catch in the direction of the closed position.
- the document DE 102010003483 AI discloses a locking mechanism in which the catch introduces an opening moment into the pawl when the pawl locks the catch in the main catch position.
- the catch may, for example due to a door seal pressure and / or due to a biased spring capable of rotating the catch to its open position, and / or introducing such torque into the pawl by opening an associated door or flap.
- the pawl By an opening moment, the pawl can be moved out of its rest position.
- a blocking or locking lever which is capable of blocking the removal of the locking pawl from its locking position.
- the blocking lever To open such a locking mechanism, the blocking lever is pivoted out of its blocking position with the help of a release lever.
- the opening moment is sufficient, which is introduced by the catch in the pawl to rust the locking mechanism, so to open it.
- the blocking lever arm of the blocking lever extend horizontally and the release lever arm of the blocking lever vertically down.
- a vertical with respect to a motor vehicle is defined.
- locks in a motor vehicle are vertically installed with respect to a longitudinal direction. If the spring of the blocking lever breaks, the blocking lever would be aligned solely by gravity when the motor vehicle door is closed, so that the blocking lever blocks the pawl in the main latching position.
- shocks for example, due to driving over an uneven surface could lead to the release and swinging out of the blockage lever from the blockage position and thus to the autonomous opening of the vehicle door or flap. The occurrence of a sham closing would therefore be possible in principle with the disclosed lock.
- the aforementioned features of a locking mechanism can be part of the invention individually or in combination.
- a lock for a door or flap, in particular for a vehicle, with a catch of rotary latch and at least one pawl for rusting the catch.
- the ratchet comprises a blocking lever for blocking the pawl in the main ratchet position.
- the blocking lever axis and / or pawl axis is arranged above (ie against the direction of gravity) of the rotary latch axis.
- the claimed lock in contrast to the prior art, is such that the blockage lever and / or the pawl would align themselves only by gravity so that, for example, when closing a door, the blockage lever would not enter the blockage position or pawl into the main latch position ,
- Gravity alone means that only gravity acts on the component under consideration, which is suspended without friction on its intended axis. Additional components for force introduction (for example, a spring, a lever or a linkage) or surrounding components with possible points of contact (for example, blocking lever, pawl or rotary latch) are hidden in this consideration. If, for example, a blockage lever is considered that aligns itself solely with gravity, the consideration includes only the blocking lever, which is suspended without friction on the blockage lever axis and otherwise experiences no further force application except for gravity.
- the lock according to the invention is configured such that a vertical runs laterally (preferably always at the same lock on the same side) through the blocking lever axis in the latched state of the locking mechanism next to the blocking surface of the pawl and / or the pawl and / or the catch ,
- the inventive arrangement of Blockade lever axis usually makes it possible to avoid apparent closure in a technically particularly easy to implement way.
- the blocking lever is shaped such that, solely by gravity and relative to the blocking lever axis, a triggering lever arm of the blocking lever produces less torque than a blocking lever arm of the blocking lever.
- the release lever arm of the blocking lever serves to release the blocking lever from the blocking position, in which the blocking lever blocks the pawl in the main detent position with the aid of the blocking lever arm.
- the Blockadehebelarm can block a pawl immediately.
- An embodiment in which the entire blockage lever is configured as a solid body (without cavities) and made of only one material provides a blocking lever arm of the blocking lever which is thicker (ie of greater cross-sectional area), wider and / or longer compared to the trigger lever arm of the blocking lever shaped is.
- a further development of the lock according to the invention provides for a rectilinear shaping and / or an eccentric arrangement of the blocking lever arm for the blocking lever axis.
- Blockadehebelarms Due to the rectilinear shape and eccentric arrangement of the Blockadehebelarms alone a minimum distance of the blocking surface of the blocking lever can be achieved to the blocking surface of the pawl in the main detent position by gravity in a particularly space-saving manner.
- the release lever arm is formed in a straight line and / or has an eccentric to the blocking lever axis arrangement in order to minimize the space.
- the blocking lever arm is arranged in blocking position to the side eccentrically to the blocking lever axis, which faces away from the blocking surface on the pawl in the main locking position.
- the release lever arm is arranged at an angle to the blocking lever arm.
- the two arms thus include an angle less than 180 degrees.
- the orientation of the blocking lever arm in the blocking position is adapted to the direction of the blocking force for holding the pawl in the main rest position. Due to the thus reduced lateral forces in the transmission of the blocking force by the Blockadehebelarm a slender Blockadehebelarm is made possible with very low weight.
- a further development provides the blockage lever with a ring shape around the blockage lever axis area, wherein optionally the outer contour of the blockage lever arm can be tangentially connected to the outer contour of the ring shape.
- the orientation of the blocking lever can be determined by gravity alone particularly easy by the difference of the torques of the trigger arm and Blockadehebelarm. Due to the favorable mechanical properties of a ring shape during power transmission, the blocking lever can be made smaller around the blockage lever axis area and thus particularly space-saving and light.
- the tangential transition from the outer contour of the Blockadehebelarms in the outer contour of the ring shape around the Blockhebelhebelachsen Scheme generally also shows favorable mechanical properties in the power transmission and therefore allows a particularly space-saving and easy dimensioning of the blockage lever.
- locking surface of the pawl and the blocking surface of the pawl are both located at the same end of the pawl of the pawl and / or at both corners of the end of the pawl each a preferably rectangular recess is provided wherein (based on the position of the pawl in the main latching position) in the upper recess, the blockage surface and in the lower recess, the latching surface are arranged for latching with the rotary latch in the main latching position.
- the arrangement of the blocking surface and locking surface at the same end of the pawl arm and by the formation of recesses for the blocking surface and locking surface a pawl is made possible, which is particularly lightweight and compact.
- the blocking surface of the pawl is aligned so that in the latched and locked state of the locking mechanism in the main detent position the blocking force is oriented to the side of the recess with the locking surface at the end of the pawl.
- the blocking force can thus be transmitted through the material between the two recesses at the corners of the end of the pawl arm.
- the blocking surface of the blocking lever and the blocking surface of the pawl are aligned so that in blocking position a counteracting the release of the blocking lever torque is introduced or the blocking lever only under elastic deformation in the Blockade position brought and can be solved again. Due to the blocking and locking surface alignment according to the invention, a lock which operates particularly reliably is provided. If, for example, a defect in one component occurs in the latched and locked state of the locking mechanism in the main locking position and if this defect could cause the blocking lever to be released from the blocking position, the blockage and locking surface alignment counteracts the opening of the lock. For example, in a vehicle, the risk of self-opening a door while driving can be reduced.
- the lock according to the invention there is an opening moment in the latched and locked state of the locking mechanism in the main latching position for moving the pawl out of the main latching position.
- the opening moment causes that in the presence of faulty or defective components, which could cause an opening of the lock, the lock can not rust in the main detent position and thus shamings can be further improved improved.
- the lock of a vehicle door with broken blocking lever spring is cited. In this case, the opening moment causes the door to rebound immediately upon closing by the user after movement into the closed position, thus indicating to the user the defect in the lock.
- the blocking surfaces and / or the latching surfaces for rusting the pawl with the catch in the main latching position are arranged between a vertical through the pawl axis and a vertical through the blocking lever axis.
- the inventive arrangement of the blockade and locking surfaces is a particularly space-saving realization of Lock according to claim 1 with a short pawl arm and Blockadehebelarm allows.
- the blocking lever axis region and the pawl axis region overlap with respect to the vertical position and extent so that a horizontal line can intersect both the blocking lever axis region and the pawl axis region.
- the rotary latch axis portion and the pawl axis portion overlap with each other with respect to the horizontal position and extension, so that a vertical is capable of simultaneously cutting the rotary latch axis portion and the pawl axis portion.
- the load arm of the rotary latch is located above the rotary latch axis and / or overlaps with respect to the horizontal extent with the rotary latch axle area.
- Figure 2 locking mechanism in the locked state in the main rest position and a self-aligned by gravity blocking lever
- Figure 1 shows the locking of a door lock of a motor vehicle in the latched and locked state in the main latching position with a catch 1 and a pawl 2 for locking the catch 1 and with a blocking lever 3 for blocking the pawl 2 in the main latching position, with above (ie against Gravity direction 7) of the rotary latch axis 4 arranged Blockadehebelachse 5 and pawl axis. 6
- the invention is explained on a consisting of several pawls, so-called Mehrklinkengesperre existing lock.
- the invention expressly refers not only to Mehrklinkengesperre, but is transferable to all other locks with a locking mechanism.
- the pawl 2 locked with its locking surface 8, the rotary latch 1, which rests with its locking surface 9 on the locking surface 8 of the pawl 2.
- the position of the locking surfaces 8, 9 to each other in this embodiment is chosen such that the rotary latch 1 initiates an opening moment in the pawl 2.
- the pawl 2 can be pivoted out of its locking position shown in the case of Figure 1 and Figure 2 by rotating about the axis 6 in the counterclockwise direction, when the blocking lever 3 by pressing the release lever 10 from its blocking position or his blockade position is moved out.
- FIG. 1 the spring torque 11 of a preloaded leg spring acting on the blocking lever 3 is shown, which is able to move the blocking lever 3 in the direction of the blocking position.
- the blocking lever 3 must be pivoted counterclockwise about its axis 5 in order to open the locking mechanism.
- the blocking lever 3 has at the end of the Blockadehebelarms 12 its Blockade Chemistry 13, which in Blocked state with the blocking surface 14 of the pawl is engaged.
- Figure 2 shows the locking mechanism of Figure 1 with the difference that the blocking lever 3 no leg spring attacks and the blocking lever 3 aligns solely by gravity.
- the state of the locking mechanism shown schematically in FIG. 2 therefore simply reflects the case of a broken pivot spring of the blocking lever 3.
- All axle suspensions for blocking lever 3, pawl 2 and rotary latch 1 are not shown in Figure 2 as well as in Figure 1.
- Due to the inventive design of the blocking lever 3, the Blockadehebelarm 12 is directed in the direction of gravity 7, so that the blocking lever 3 can not pivot by gravity alone in the blocking position. In the embodiment shown, the occurrence of an apparent closure is thus avoided.
- the blocking lever axis 5 is arranged so that a vertical ⁇ 5 runs through the blocking lever axis 5 in the latched state of the locking mechanism in the main locking position laterally next to the locking pawl 2 together with its blocking surface 14 and beside the rotary latch 1.
- a torque-neutral ring shape 16 around the blocking lever axis 5 surrounds the blocking lever axis region 17 and is connected to the trigger lever arm 10 and the blocking lever arm 12.
- the Blockadehebelarm 12 is rectilinear and also thicker and longer than the Auslasshebelarm 10 so that the Blockadehebelarm 12 together with Blockade patterns 13 aligns only by gravity down.
- FIG. 2 shows an additionally enlarged distance between the blocking surfaces 13, 14, which is caused by the blocking lever arm 12 arranged eccentrically to the side facing away from the pawl 2.
- Figure 1 have the straight shape and the pawl 2 side facing away eccentric arrangement of Blockadehebelarms 12 at the same time the advantage of a mechanically favorable orientation to the similarly oriented Blockadekraftraum 20 of the blocking force for holding the pawl in the main detent position.
- a rectangular recess 22 on the lower side for the latching surface 8 and a rectangular recess 23 on the upper side for the blockage surface 14 are introduced at the corners (FIGS. 1, 2).
- the blocking load direction 20 is oriented starting from the blocking surface 8 in the recess 23 to the side of the recess 22 (Fig.1).
- a very compact and at the same time robust construction of the pawl and the locking mechanism is made possible.
- the components of the locking mechanism in the embodiment of Figures 1 and 2 are arranged according to the invention.
