Description

GERMAN

The invention relates to a method for coupling and / or locking or uncoupling and / or unlocking of locks of articulated caps connected to one another by such, as well as for implementation devices suitable for this process.

The locking of the lock of hinged caps, which is often associated with circumstances, in the course of the pre-pledging process makes particular difficulties when it comes to comparatively long caps, because the man installing the cap is at the butt end of the cap and during the pivoting process is therefore not able to operate the lock, namely the Tensioning wedge or the like to drive, or in the case of appropriately designed caps in which d.er Hinge pin is only introduced at a later point in time to push this into the lock.

The invention creates a very simple way of doing this in that the coupling and / or locking elements (hinge pins, locking rings or the like) in not yet or not yet finally swiveled up position of the cap to be built in a lock part of this cap inserted, under the effect of pressure or tension on a fixed point, preferably on one of the caps funds used are brought and that. by now swiveling up the to be built Cap a path blocked until then by parts of the same is released in such a way that the coupling and / or locking elements under the action of clamping devices in their approximate or final, the lock parts of both caps penetrating locking position are moved.

In this case, the means exerting pressure or tension are used prior to the introduction of the means to be preconstructed The cap is blocked in its later released position and this pre-blocking is released after insertion loosened the cap to be pre-assembled.

As such means serve according to a preferred embodiment of the invention between a fixed point and one end of the coupling and / or locking element used under Voltage applied initially locked element, that when releasing the locking of the coupling and / or locking element.es of the cap connection drives into the coupling and / or locking position.

Such a locked element under tension can, for example, be a rod spring or the like. Use one end of which is attached to one of the cap to be connected, preferably to the Coupling and / or locking element carrying cap and with the tensioned other end on the Coupling and / or locking element engages.

Instead of this rod spring, a helical spring, a highly elastic rubber body, a compressed air bolt or the like can be used.

According to a preferred embodiment of the method according to the invention, the triggering takes place of the element under tension in that, with a corresponding formation, the one another interacting lock parts, simply in the course of the vertical pivoting of the cap to be preinstalled the entry path of the transversely displaceable locking elements previously blocked by a part of the cap itself is released.

In the context of the invention, it is important that the locking element is also prior to its displacement in the effective position in the proper, the insertion enabling, namely is in alignment with the insertion path. To this end, according to a further feature of the invention, if necessary, devices on the cap, e.g. in the form of an elastically flexible device Loop or bridge attached, which inevitably hold the wedge in this position against gravity.

The use of these funds also proves to be more beneficial when in the case of short caps the live element can be dispensed with and driving in the wedge, as previously usual, done by hand.

The new device is basically in completely the same way, only to be adapted accordingly for the introduction of the hinge pins as well as the locking elements, namely those of any Training, usable, in the case of their

009 627/84

Use of a known device for inserting the hinge pin on the cap is arranged in the form of a push-through transverse pin to which the cap to be preinstalled initially is appended to be pivoted upwards on its axis, below a course of this Movement that inevitably brings the bolt holes into an aligned position at the end will.

In the drawing, exemplary embodiments of the device according to the invention are preferably shown. They are described in more detail below and the handling and operation of the device explained on the basis of the illustrations.

Figs. 1 to 3 show in side view, in plan view and in a partial front view one for carrying out the method according to the invention using a particularly expedient embodiment of the slide-in device according to the invention particularly suitable articulated cap lock of known design, consisting of fork 1, the to be considered as supported cap 2 and the tongue 3 of the vorzupfändenden cap 4 and the Coupling bolt 5 and the locking bolt 6, which with its inclined strip 7 with a surface of the inclined gap 8 of the tongue 3 corresponds. On the handle 9 of the rod 6 adapted to the insertion path of the bolt 10 of the insertion device, which engages with its tip in the head 11 of the bolt 6, attached two coil springs 12, one of which is arranged on the right and one on the left of the linkage 10, are in on. the fork 1 arranged eyelets 13 hooked.

According to Fig. 2, the device is in the state the tension and readiness to work and requires the bolt 6 protruding from the fork 1 to slide it into the lock, only to release it by inserting the solid lines in it in Fig. 1 position shown the latch with its tongue clamping cap 4 by the installation man in the direction swiveled up to its position shown in dash-dotted lines and thereby the bolt the way into the Lock is released.

Fig. 3 shows the relaxed device after the disinhibited latch according to the progression of the swiveling up process of the cap 1 into the lock up to the head. Depending on The operator can of course initiate the insertion process before reaching the circumstances and requirements end the end position of the bolt by simply letting go of the cap.

As shown in Fig. 3 by dash-dotted lines, the insertion direction can also be below of the cap lock, wherein the linkage 10 'of the spring 12' is expediently designed as a hook is.

With the completion of the pushing-in process of the bolt, the entire installation process of the cap is complete completed. The relaxed insertion device can now be removed again in order to then use the The bolt of the next Kapperi lock can be operated. At this is the device according to the first described embodiment for this purpose in the Eyelets 13 hooked after first pulling out the bolt 5 as shown in Fig. 2 and the pre-plucked The cap is brought into the continuous position shown in FIG. 1 and coupled by the hinge pin 5 has been. The device is then tensioned by pulling on the handle of the rod 10 and through Inserting the tip of the rod into the head of the bolt brought into its operative position. Can the device can be restarted in the manner described above.

The same slide-in device can be used in a similar manner also used for the mechanical introduction of the coupling bolt 5 into the cap lock will,. if, as indicated by dash-dotted lines in Fig. 2, an eyelet 13 'or the like is arranged on the fork is. Here, however, is a prerequisite that the cap to be vorzupfändende while the device from Operator is cocked with your tongue on the bar 7 of the bolt 6 and with its other end can rest on the sole at such an angle that the bolt holes of the fork and tongue of the Locks are not aligned with each other, so that the tongue is pressurized by the device Bolt locks. If the cap is then pivoted up around the bar of the bolt as a pivot axis, there is the tongue allows the bolt to enter the lock at the moment when the cap is the one shown in Fig. 1 position shown, in which the pin holes of the fork and tongue overlap each other, has reached. The slide-in device can then be moved to the bolt in order to now close it serve.

Fig. 4 shows a cap lock in which the tongue is used for temporary locking the insertion device is even better adapted by using a plug-in auxiliary axis 14 cooperating hook 15 is equipped, around which the cap can be pivoted up. This design of the lock enables the lock tongue to be used as a locking means for itself the bolt placed under pressure by the device in a larger angular range than the training according to Fig. 1.

Fig. 5 shows the same slide-in device as Figs. 2 and 3, attached to the coupling bolt 5 ' a partially shown cap lock, in which a blocking of the bolt, however, is not takes place through the tongue of the cap to be pledged. Rather, it is the cocked slide-in device locked by means of a spreader 16, the end of which swings up the cap to be pre-pounded Installation man for the purpose of triggering the insertion device at the given time from a distance z. B. triggered by means of a rod or chain can be.

Appropriately, to unlock the spreader 16, a device that can be operated remotely is used, for example one attached to the cap to be pre-pledged, not shown in the figure Angle lever that pulls the spreader 16 out of its drawn in Fig. 5 when the cap to be pre-pounded is lifted Strikes away position and thereby releases the spring 12.

Fig. 6 shows a partial representation of a cap lock, in which a simple wedge 6 'serves as the locking element of the lock, which the locking bolt 6 according to Fig. 1 to 3 given complete guidance and bracket in the fork is missing. A Such a wedge can only be operated by means of the mechanical insertion device according to the invention, if it is brought up into the position aligned with the direction of insertion before the device is attached and is supported in this by a suitable means.

An embodiment of such means is shown in Fig. 6 and in another view in Fig. 7 in the form of resiliently arranged bridge 17 and a similar embodiment in Fig. 8 in the form of the one-sided resiliently attached bridge 17 'shown. These

Wedge support device can, as is not shown, for. B. also a bolt that can be pushed under the wedge or the like. The insertion device attached to the wedge is shown by dash-dotted lines in Fig. 6 indicated.

Fig ¹ . 9 and 10 show in two different embodiments. How the insertion device according to the invention, for. B. can be formed when eyelets 13 or the like. For attaching the device to the cap are not available. As can be seen, in the embodiment according to Fig. 9, the tension spring 12 ″ is hooked into the bolt 6 and can be tensioned by means of the extension chain 18 and attached to a fixed point then outside the cap, e.g. on the neighboring cap.

In the embodiment according to Fig. 10, the compression spring 12 '"arranged in the cylinder 19 acts on the rods 10" which engage in the head of the bolt and are designed as a piston, the trigger 20 if necessary forming the disengageable locking member of the device. By means of the attachment piece 21 of the cylinder 19, the device can be supported on the adjacent cap, if necessary with the interposition of a bolt or the like. With an appropriately adapted design of the device, the piston W can also be actuated by compressed air instead of the spring.

In Fig. 2 there is another one that differs greatly from the examples described by dash-dotted lines Embodiment of the one-thrust device according to the invention shown. This consists of one with its end attached to the cap 2 by a protruding body 22 and with the other End at the head of the bolt to be inserted 6 attacking rod or leaf spring 23. As can be seen, this spring is bent towards the cap when it is not under tension. By bending the spring in the opposite direction Direction it is stretched and can then, if necessary, by means of a spreader analogously to the Fig. 5 can be locked.

Like the method according to the invention and the to its implementation proposed new device on the dismantling side of the strut the installation process of joint caps significantly, so by reversing their direction of action, they can possibly in appropriately adapted or modified training, on the offset side also for To facilitate the robbery of the joint caps in an advantageous manner. This is the embodiment according to FIG. 9 is particularly suitable. You can easily solve the Bolt or the locking element can be used from its operative position in the lock, in which Usually just a blow of the hammer on the tip of the device under the mechanical pulling effect Element is sufficient to loosen it so> far that the actual pulling out of the element through the effect of the mechanical force of the device, which also persists during the loosening process can be done.

The embodiment according to Fig. 10 can be adapted to this purpose even more effectively by adding the Piston-shaped bolts 10 "so reinforced and under the action of compressed air or the like. Is set that he pushes out the hinge pin 5 clamped in the lock without loosening it by striking it with a hammer can.

With a suitable design, the modified in this way from the embodiment according to Fig. 10 Embodiment, in particular by stepping in place of the support against the neighboring cap suitable Anchoring of the cylinder 19 to be enlarged accordingly by a linkage or the like with the the locking element carrying cap, it is also possible to use the locking element by means of the new Device not only with simultaneous ventilation of the same by what was previously done by human power Swing up the vorzupfändenden cap to slide into the lock, but on the bolt or wedge to act with so * strong mechanical force, that this in turn the vorzupfändende cap by pressing down the front part of their Tongue swung up and also pressed against the hanging wall, so that the paver also can be freed from this hitherto difficult work.
