The invention relates to a device for temporarily securing an articulated connection between two caps supported by stamps against buckling downwards, which is required is when one of the punches that previously prevented the joint from buckling is temporarily removed should be, z. B. to create the opportunity to back a funding.

The device according to the invention is particularly suitable for consisting of a fork on one side and one in this engaging tongue on the other cap, which penetrates through a fork leg and tongue Bolts are connected, determined existing articulation. It insists on its basic idea after one in two-sided projections of the cap profile carrying the fork for the time of use of the device, d. i.e. until the supported Stamp can be set again, attachable bracket from the gutter profile, on the bottom of which a wedge body is displaceable, which one in turn by stops on the bracket against lateral displacement secured rider who is raised by the longitudinal movement of the wedge in the vertical direction or is lowered. The rider comes with his upper face to the supporting system on the lower surface of the front part of the preferably elongated tongue of the articulation and prevents this causes the tongue to pivot downwards and consequently a downward buckling the connection point around the hinge pin.

By moving the wedge under the tab, it is brought to the required height, which varies depending on the angle that the cap connection to be secured against buckling forms is brought. To compensate for heights that may not be fully accessible by means of the wedge can be an attachment piece to be placed on the rider, suitably loosely chained to the device be provided.

In order to destroy parts of the cap connection or to prevent the locking device, according to a further feature of the invention Rider body given a certain, preferably only gradually extending resilience, z. B. by it is formed by a hollow body, which is gradually under constant stress under load or slightly increasing resistance can flatten, which among other things by a towards one end of its longitudinal extension gradually reinforcing formation of this hollow body can be reached.

The details and further features of the invention will become apparent from the following description an embodiment of the new device on the basis of the figures. Of these shows

F i g. 1 is a side view of the joint two caps with the attached, anti-buckling device according to the invention;

FIG. 2 is a section along line AA of FIG. 1;

F i g. 3 and 4 show, on an enlarged scale, a side and front view of a preferred embodiment of the interchangeable rider.

In the figures with A, the η with the relatively long coupling tongue provided end of the one and labeled B, designed as a coupling fork end of the other cap, each supported by a punch and η by means of the tongue and the fork of the cap B penetrating hinge pin ο are articulated to one another.

The device according to the invention, which is used to secure this joint against buckling downward, consists, according to the preferred embodiment shown, of a trough-like bracket i, which is stiffened by welded metal sheets k and which is known per se in cap shoes, and which engages over the side ribs of the cap with hook-like attachments ρ and p ' and is suspended from it. The cap itself shown in the figures is of a new type of box profile, the special features of which are clearly evident from the drawing.

The bracket is attached to the cap profile by first hanging its one leg hook ρ on one of the side strips of the cap profile and then passing the other bracket leg hook p ' through a

recess q provided for this purpose on the other side strip of the cap profile and subsequent displacement in the longitudinal direction of the cap, in a manner similar to that when adjusting a bayonet catch.

On the bottom of the bracket i , appropriately designed recesses, are guided displaceably in the welded metal sheets k , the wedge body 1 is mounted, on the inclined upper surface of which is secured against lateral movement by stops formed on the bracket, against it by the movement of the wedge 1. and downwardly moving replaceable rider body m is placed. This rider body engages in the forked gap of the cap B, in which the tongue η of the cap A extends and, when the wedge is driven in, its upper surface rests against this tongue, which is thereby blocked against pivoting downwards.

According to the preferred Ausfüh- ao iungsbeispiel shown, the rider body m is pressure-resilient, so that the rider body first yields while avoiding sudden yielding in the event of an overload of one of the lock parts of the cap connection and thus also prevents destruction of the stirrup body. According to a special feature of the invention, this flexibility is achieved by a corresponding design of the rider body, a preferred embodiment of which is shown in FIGS. 3 and 4.

As can be seen from this exemplary embodiment, the rider body, which is provided with a downwardly opening slot r , has a channel-like profile and may carry the top section s indicated by dash-dotted lines, gradually increasing in one direction, so that its pressure resistance increases in the course of its use continuously increased by a small amount by the lock tongue, but at least cannot stop suddenly.

The blocking device according to the invention is usually used in each case before the stamp, which secures the connection point of two caps against kinking until then, is removed. As soon the stamp has been set again later, the device has fulfilled its task and can now be used again at a different location.

Of course, the invention is not limited to those described in detail above and in the Illustrations shown embodiment limited, but there are numerous Changes are possible without deviating from your basic idea. So in particular, in order to gain height To save, instead of the wedge described for operating the rider's body, one from below is also closed operating, acting in the vertical direction on the rider's body, preferably from two telescopic Spindle existing in one another moving parts can be used. Furthermore, it is in the case of one Wedge as an operating means for the rider not necessary that this in the longitudinal direction of the caps is arranged. Rather, with a corresponding design of the overall device, a transverse wedge can also be used be used.

Claims (3)

Patent claims: 1. Device for temporarily securing a fork and tongue with it penetrating Bolt formed joint connection of two caps supported by stamps against Buckling, characterized by one that can be attached to the lateral profile projections of the caps Channel-like bracket, on the bottom of which a wedge body is displaceable, which one rider body secured against displacement in the tightening direction of the wedge, which in such a way is raised or lowered by the longitudinal movement of the wedge in the vertical direction and with its upper end face on the lower face of the front part of the tongue of the joint presses. 2. Device according to claim 1, characterized by a switched on between tab and tongue, The attachment piece that transfers the pressure of the rider's body onto the lower surface of the tongue. 3. Apparatus according to claim 1 and 2, characterized in that the rider body according to is gradually reinforced towards one end of its longitudinal extension.
