Description

Crankset closure.

The invention concerns a connecting rod closure drive with a main lock on the leaf side of a door, key operated and equipped with a main latch, as well as with a drive rod that, by actuating the lock main, it can be moved along a locksmith to actuate a lock latch of an additional lock that cooperates with a swinging footboard on the side of the fence of the door.

A closure of the connecting rod of the commented class is known from document DE 35 03 466 C2, where the run of the additional lock lock latch is effected by middle of a handle located on the inner side of the door. The locking latch is brought to the release position at unhook the latch from the main lock. This it means that unlocking the door opens not only the lock Main, but also the additional lock.

It is also known by the document DE-GM 29 50 950/3 the resource to also move the additional lock lock latch by means of a handle on the inner side of the door. In this embodiment the additional latch still does not move towards the uncrowned position when unlocking the main latch of the main lock, of so that the locking latch remains still coupled with the locking stirrup Just by running the latch again main moves the additional lock lock latch towards the position unlocked by driving the connecting rod. The main latch is then coupled. Whether unclog this latch again, the door can be opened. Is common to both executions cited above the fact that the run The locking latch must always be carried out by hand by separated.

The object of the invention is based on the problem of configuring a crankset closure of the aforementioned class of so that, apart from a simplified operation, the value is increased of security.

This technical problem is solved first place and substantially in a drive rod closure with the characteristics of claim 1, wherein it is stated that after a first drive the main lock has the additional lock lock latch towards the closing position together with the main latch under the drive the drive rod and after a first drive off the main lock has been unhooked the main latch while after a second de-energized drive the latch has been unlocked blocking.

As a result of this execution, it has created a crankshaft closure of the aforementioned class that, apart from a simplified drive, it is characterized by a increased security value The simplified drive it turns out that by running the main lock latch main by means of the key the lock latch of the Additional lock arrives at the same time to its run position. By therefore, there is no need to perform a separate closing drive for run the additional lock lock latch. It results from this also increased security value. In fact, it can't occur that when running the main latch is omitted by forgetting the run of the locking latch. Therefore, after a drive operation of the main latch always occurs the closing coupling of the main latch and the latch of blocking. Likewise, the advantage that only unhook the main latch after a first drive off the main lock. The uncorked latch lockout is performed only after a second drive off the main latch, specifically also by key operated

An advantageous improvement is that the main latch between the drives is run again of first and second offspring. Therefore, if you run again the main latch after the first drive of off, both the locking latch and the main latch They are in the running position. Then both arrive together to the unraveled position when the second occurs dehorred drive.

So, after the latch of lock and main latch, lock latch remain in its advanced position when the first drive of off, a specially arranged coupling is provided in the additional lock, which disengages the lock latch of the lock drive during the first drive of run.

In a simple way, the coupling presents for this, a means of insertion that keep the latch of lock in the run position and whose insert position is canceled at the second de-run drive.

In a constructively simple way, it has proceeded to provide a first locking finger that maintains a slide arranged on the locking latch in a first insertion position, whose locking finger is retracted in the first off-position and releases the slide so that it move to a second locking position in which the slide is held by a second locking finger that is retracted in the newly run position of the main latch and releases the slide to cancel the locking of the locking latch. By therefore, the blocking fingers are successively transferred to their release position. When the first drive of off, the first locking finger thus reaches a position of Sliding release, after which it can be moved to the second insert finger. The travel path of the slide is so large that the locking latch remains still in Your advanced position. Only in the run again position the second locking finger is retracted from the main latch and it allows the slide, requested by spring, to continue moving on the locking latch and then release the insert of said lock latch. Then, when the second occurs drive off the lock latch reaches its retracted position.

The solution of the problem of the invention can achieved in a closure of the connecting rod of the aforementioned class of such that the locking latch is provided to be run under the control of the drive rod to an integrated position from which, when the insert is canceled under the control of the drive rod, the locking latch is moved back by the force of a spring pressed back tensioned during the run of the latch.

We proceeded here so that the latch of lock is run to the locked position when a first displacement of the drive rod, be brought to a position trigger when a second crank movement occurs motor and gets off when a third displacement of the drive rod.

Another advantageous feature of the invention is that, during the first running drive, the slide is also displaced by means of a drag lever arranged in the locking latch, which is removed in the phase end of the run drive to a release position of the slide. However, the slide is already retained then in position by means of the first blocking finger.

The control of the locking fingers is carried out by simple way by means of a first projection arranged in a connecting rod of the connecting rod, which displaces the first back finger lock, especially through a rocker, and for a second projection arranged in the connecting slide of the drive rod, which moves the second locking finger towards back when the second drive of the drive rod occurs.

To be able to run and uncork the lock latch regardless of the drive main lock, the lock latch is coupled through of a zipper with the teeth of a lock nut additional to manually activate the locking latch.

We have proceeded here simply so that, in its de-driven drive, the nut operates a trigger to move back the second locking finger. This can be properly coupled with the first locking finger, with which the first blocking finger passes simultaneously to its backward travel position.

Finally, an advantageous feature it still consists in dragging the locking latch towards the running position is effected through the oblique wall of a wedge-shaped slit that widens wedge-shaped. At second drive off this groove allows the recoil shift of the low locking latch spring request.

With the number 1 it is designated in figure 1 a door that is articulated in a door fence 3 by means of hinges 2.

On the opposite side of the hinges 2 the door gives housing at a 4-wheel drive closure. The latter has a door lock 5 on the side of the door with a lock main 6 fixed in it. Above it is in the lock 5 an additional lock 7 configured as a lock Stirrup lock. This means that your stirrup lock 8 cooperates with a locking bracket 9 articulated by the side of the encircled and longitudinally cleft. Above the lock additional 7 is also a latch lock ten pin. This corresponds in its structure to the lock of herringbone latch 11 arranged below the lock main 4.

The main lock 4 is equipped with a slip 12 and a main latch 13. It can be run and preferably loosen with two turns by means of the key operation. Simultaneously with a scroll from the main latch 13 a driving connecting rod 14 is moved by the lock 5, which transmits its movement to the lock additional 7 and to bolt locks 10, 11.

In particular, the additional lock 7 has a lock bottom 15 attached to the lock 5, parallel to the which extends a lock cover 16. In space intermediate between the lock bottom and the lock cover 16 are the guts of the lock. These are constituted by the locking latch 8 guided in the middle plane transverse of the lock. Its 8 'latch head goes through a port 17 of the lock 5 built with cross section adapted, while the 8 '' tail of the latch is guided by of spikes 18 protruding on both sides in indentations cross-sections 19, 20 of bottom 15 and cover 16 of the lock. Directed down, the 8 '' tail of the locking latch continue on a gable 21. This forms a zipper 22 that runs parallel to the direction of travel of the latch of block 8 and cooperating with the teeth 23 of a nut 24. This one is mounted in a known manner at the bottom 15 and on the cover 16 of the lock. Radially directed, part of the nut a stop 25 that penetrates an arched groove 26 of the cover 16 of the lock. The arched groove 26 has been chosen so long that the Walnut 24 is able to perform a 90º turn. Figure 1 illustrates a inner drive handle 27 that is attached so suitable with nut 24.

On the opposite side of boom 21 the tail 8 '' of the latch carries a small support block 28 for a lever drag 29 with two arms. A torsion spring 31 arranged on the support shaft 30 of the drag lever 29 loads the lever drag 29 in the opposite direction to the direction of rotation of the clockwise such that the lever arm 29 'turned towards the locking latch 8 it rests on the longitudinal edge upper locking latch 8; see figure 3. On the other lever arm 29 '', which encloses an obtuse angle with the arm lever 29 ', attacks the torsion spring 31 mentioned above.

On a quadrangular spike 32 of the bottom 15 of the lock is connected to a spring 33 pressed backwards spiral-shaped winding that loads the locking latch 8 in Direction in the lock. Between the latch of lock 8 and the cover 16 of the lock is guided by a slide 34 connecting rod of the connecting rod. This is coupled with the end sections 14 'of the connecting rod 14 divided at the height of the additional lock 7. In the rear area away from the lock 5 the connecting rod 34 of the drive rod has a groove cuneiform 35 that widens wedge-shaped and penetrates the pin 18. The locking latch 8 is run here through the oblique wall 35 ', which runs obliquely to the locking direction of the locking latch 8 and that continue on the upper end in a niche 35 ''.

On the side turned towards strike 5 the connecting rod 34 of the connecting rod has a recess 36 which is separated from the cuneiform cleft 35 by a bridge narrow longitudinal 37. The longitudinal bridge 37 supports a slide 38 that hugs the locking latch 8. A spiral spring 39 requests the slide 38 towards the longitudinal bridge 37. The arm 29 'of the drag lever 29 it ends a short distance from the rear edge of the slide 38; see the starting position of figure 3. The other arm 29 '' of the drag lever 29 cooperates with a stop 40 on the bottom side of the lock.

The wide side walls 38 'of the slide 38, turned towards the bottom 15 and the cover 16 of the lock, each of them has a longitudinal groove 41 which is open back and running in the longitudinal direction of the latch. The inner ends of the longitudinal grooves 41 are formed here in the form of control chamfers 42. Each control chamfer 42 cooperates with the angled end 43 'of a respective laminar spring 43. Its width is somewhat smaller than the width of the longitudinal grooves 41. The leaf springs 43 are fixed on both sides of the tail 8 'of the latch, specifically on opposite sides of it; see figure 10. Each laminar spring 43 carries an insert 44 in the form of a plug pin. These insertion means 44 penetrate the longitudinal grooves 41 of the slide 38. Due to the spring pre-tensioned, the coupling means 44 are pressed against the bottom 15 and the cover 16 of the lock. The means of inlet 44 cooperate with inlet openings 45 in bottom 15 and the 16 lock cover.

The insertion means mentioned above - spikes insert 44 and insert openings 45 - form a coupling which keeps lock latch 8 in the run position, which which is explained in more detail below.

On its lower side the slide 38 carries a chamfered locking extension 46. The latch being lock 8 shifted backward, this extension extends between a first blocking finger 47 and a second blocking finger 48 that are guided transversely to the direction of movement of the locking latch 8 in a housing 49 fixed to the bottom 15 of the lock. A compression spring 50 loads the first finger of lock 47, secured against rotation, in the direction of the latch lock 8. The lock finger 47 forms at the upper end a cap 47 'chamfered as a slip and intended to cooperate with the extension of blockade 46. Radially directed, part of the first locking finger 47 a drag pin 51 that crosses a longitudinal groove of the housing 49 and cooperating with a rocker 52 mounted on the bottom of the lock. An arm 52 'of rocker cooperates here with the drag pin 51, while the another arm 52 '' of the rocker arm rests, according to figure 3, on a first projection 53 of the connecting rod slide 34 motor The lower end of the locking finger 47 protruding from the housing 49 carries a transverse pin 54 that crosses a longitudinal groove 55 of a shoe 56 plugged into the lower end of locking finger 47. This shoe has a coupling pin 57 running at right angles to the second locking finger 48. Said pin passes through a slit 58 of the lower end of the locking finger 48. The end of the coupling pin 57 projecting in radial direction plus beyond the second blocking finger 48 and which is enlarged in section transverse is requested by an arm 59 'of a trigger 59 of two arms mounted on the bottom 15 of the lock. A pier traction 60 loads trigger 59 counterclockwise clockwise direction such that the arm 59 'is rests on the coupling pin 57; see figure 4. The other arm 59 '' opposite arm 59 'cooperates with a radial cam 61 of the nut 24. The second locking finger 48 secured against turning in the housing 49 is loaded by a compression spring 62 in direction to the slider 38 such that the upper end of the second locking finger 48 rests on the lower side of the slide 38; see especially figure 4. At the end lower the second locking finger 48 has a cam 63 which protrudes flown in the direction of the connecting slide of the connecting rod and cooperating with a second projection 64 arranged in the connecting rod 34 of the connecting rod.

The following operation is established:

When running the main latch 13 of the main lock 6 the connecting rod 14 experiences a scroll down. Simultaneously, slide 34 of the additional lock 7 provided for connecting the drive rod It is also dragged down. Through the wall oblique 35 'of the cuneiform cleft 35 and in cooperation with the pin 18 of the tail 8 '' of the latch, the locking latch 8 experience a forward displacement in the direction of entanglement Lock latch 8, when moving towards forward, drag the slider 38 through the lever drag 29. In the final phase of the run offset of the lock latch 8 the locking pins 44 found at the leaf springs 43 they enter the grooves 45 of the bottom 15 and the cover 16 of the lock, whereby the lock latch 8 is disengaged from the drive of the lock during the first drive. Then the arm 29 '' of the drag lever 29 requests the stop 40 of the side of the lock case and tilts to a position of release according to figure 5. During the advance travel of the slide 38 together with the locking latch 8 the blocking extension 46 has exceeded the first blocking finger 47, so that the blocking extension 46 is then located in front of the stop 47 'of the first locking finger 47. The second finger lock 48 extends behind the slide 38 after the first closing drive of the main lock and is supported on the lower side of the locking latch 8; see also the Figure 5. During this nut run drive 24 the radial cam 61 turned in turn has also exceeded the arm 59 '' of trigger 59. The rotation drive of nut 24 has been transmitted here to the inner drive handle 27.

Also, Figure 5 illustrates that the head of latch 8 'provided with an annular groove 8' '' has been coupled with the locking bracket 9 on the fence side of the door of such so that the locking bracket 9 and its cleft extend to the ring groove height 8 '' '.

During the first drive off the main lock 6 will release the main latch 13. Also, the connecting rod 34 of the connecting rod moves in direction up, stumbling the first ledge 53 of the connecting rod 34 of the connecting rod against the arm 52 '' of the rocker 52 and making it swing in the direction of the needles of the clock; see figure 6. The arm 52 'of the rocker retracts the first locking finger 47 through drag pin 51 with release of the slide 38, which, under the action of the spring coiled 39, passes from the first insertion position above  occupied to the second insertion position. This is limited by the second locking finger 48, which is requested by the side rear of the slide 38. The position of the slide moved backward in this measure is illustrated with dashed line in the Figure 11. The control chamfers 42 do not move then yet the ends 43 'of the leaf springs 43, so that the plug pins 44 remain embedded in the openings of insert 45. Therefore, lock latch 8 continues to occupy its advanced position, while the latch has been unlocked main 13.

The recoil shift of the latch lock 8 requires a new lock run drive main 6, and the main latch 13 then moves towards ahead. Also, the connecting rod 34 of the connecting rod moves starting from figure 6 in the downward direction, achieving the position according to figure 7. Using the second projection 64 of the connecting rod 34 of the connecting rod is then request cam 63 of lock finger 48 and this is thus brought to the release position of the slide 38. This one can be displaced by the force of the spiral spring 39 with in relation to the locking latch 8 and, after the displacement, rests on the small support block 28 of the lock latch 8. However, the travel travel corresponding is enough to request the leaf springs 43 at its ends 43 'by means of the control chamfers 42, with what the insertion pins 44 leave the openings of insert 45; see the representation of points and strokes in the figure 11. Lock latch 8 is then still retained only by the cuneiform cleft 35. Yes, starting from this position, the second drive is removed from the main lock 6, connecting rod slide 34 motor then moves in the upward direction, so that retracts lock latch 8 due to spring 33 backward, then sliding pin 18 of tail 8 'of the locking latch along the oblique wall 35 'of the cuneiform cleft 35. Simultaneously with the retraction of the locking latch the nut 24 is turned 90º backwards due to the teeth. Cam 63 of nut 24 then goes through above trigger 59, which necessarily deviates elastic and then returns again to its starting position according to figures 3 and 4.

However, it is also possible to carry the lock latch 8 to run position exclusively by means of a handle drive. Under the turn of the nut 24 linked to this the locking latch 8 moves in the direction of run through the teeth. The drag lever 29 displaces the slide 38 and is secured by the first locking finger 47; see Figure 8. The locking latch 8 is embedded in this position run because the spikes 44 fit into the locking openings 45. The second locking finger 48 extends in front of the rear side of the slide 38. Also, the cam radial 61 has passed over trigger 59. The movement of Turn of the nut 24 is limited by the arched groove 26. Yes the nut 24 now experiences its de-driven drive, the cam radial 64 then requests trigger 59, which makes through of the coupling pin 57 which both the first locking finger 47 as the second blocking finger 48 are retracted to a release position. Therefore, the slide 38 has been released for its displacement, canceling the interlocking between insertion pins 44 and insertion holes 45, whereby the Lock latch 8 can retract under spring load. This it is possible because the spike 18 is in the most area large of the cuneiform cleft 35.

However, it is also possible that, after first drive off the main lock, it retract the locking latch 8 by sliding the handle. He blocking finger 48 is then also removed from its position of retention of the slide 38 by means of the radial cam 61 of the nut 24, after which this slide moves in the direction of the 8 '' tail of the locking latch and cancels the insertion of this latest.
