"Locking pins for scaffolding"

The innovation relates to a socket pin for scaffolding with a wire loop securing the socket pin against unintentional pulling out. The socket pin is used to prevent other parts of the scaffolding, which are attached to a scaffolding tube, in particular a support, from being axially Move to secure on the pipe. The socket pin is for this purpose with the wire loop in the longitudinal direction over the Scaffold tube pushed over and then under tension of the wire loop into a transverse bore provided for this purpose in the scaffold tube inserted.

It is known to weld such a wire loop to the outside of a pull ring welded to the socket pin. A however, such welding on the outside of the ring is relatively cumbersome and also inexpedient.

The main purpose of the innovation is to make it simpler and more functional Connection of the wire loop to the socket pin and consists essentially in that the socket pin with a provided as a handle serving open bracket and the wire loop is connected to one end of the bracket.

Such a design of the handle and wire loop provided

Socket pin enables a quality clean and essential advantage adhesive fastening of the wire loop. Another / benefit of the Another innovation is that the arrangement of the open handle offers the possibility of using the socket pin directly hammer a hammer into the cross hole of the scaffold tube, without the bow being stressed in this case.

The wire loop can be attached to the lateral ends of the U-shaped Bracket or to be connected to middle approaches of the bracket, which are preferably adjacent to the socket pin and can be firmly connected to both the bracket and the socket pin, e.g. by welding.

In a further embodiment of the innovation, instead of a single bracket, two brackets are on opposite sides Arranged on the sides of the socket pin and firmly connected to it - e.g. by welding - with the wire loop attached to the Socket pin is connected to adjacent ends of the bracket.

It is particularly advantageous here if the bracket ends or the lugs are provided with longitudinal bores and the ends of the Wire loop are inserted into the longitudinal holes. The wire loop is not welded to the temple ends necessary. Rather, the connection of wire loop and bracket is advantageously carried out by gluing. Such a connection offers the essential advantage that annealing takes place as in welding or soldering, and the connection as a result No heat treatment remains elastic.

According to a further advantageous feature of the innovation, the wire loop is provided with a plastic sheath. Such Cover enables the sling to be pushed over the scaffolding tube more smoothly and offers greater security against injury to a person person working on or passing by the scaffolding. The plastic cover can be used to connect the Wire loop serving temple ends or approaches extend. Furthermore, the socket pin can be welded to the side of this Be provided with stop elements to limit the insertion stroke.

Three exemplary embodiments of the innovation are shown in the drawing in FIGS. 1 to 3.

In each of the figures is the cross section 10 of a scaffold tube with a cross hole 11 and one to be secured on the scaffold tube Part, e.g. of a connecting sleeve 12, indicated by dash-dotted lines. The socket pin 13 is inserted into the transverse bore 11.

In the embodiment according to FIG. 1, the upper free end of the socket pin 13 is welded to a bracket 14 serving as a handle, its free rearward ends at 15 sleeve-shaped are reinforced. The reinforced ends have blind bores 16 into which the ends 17 of the wire loop 18 are inserted and are glued in the same. The wire loop 18 is with a Plastic sleeve 19 is provided, the ends 20 of which expediently extend over the ends 15 of the bracket 14 or are slipped over them are.

To limit the insertion stroke of the socket pin 13 into the transverse bore 11 of the scaffolding tube 10, there are steep stops 21 welded to the socket pin 13 or otherwise connected to it.

As a result of the direct connection of the bracket 14 to the free end of the socket pin 13 can easily hammer blows in the direction of the arrow χ on the bracket 14 and thus on the socket pin 13 without the bracket is stressed on bending and the hammer blows a bracket member serving as a handle stands in the way.

To remove the socket pin can the same gripping Hand comfortably with the fingers on both sides of the socket pin 13 grasp the bracket 14 and even with greater resistance from the Pull out the cross hole 11 of the scaffold tube.

The embodiment of FIG. 2 differs from that 1 in that a bracket 114 is also connected directly to the free end of the socket pin 13 by welding is, but the wire loop 18 is connected to sleeve-shaped lugs 115 instead of the free ends of the bracket 114. Similar to the reinforced ends of the bracket, these are provided with blind bores 116 into which the ends 117 of the wire loop 18 are inserted and glued into it, and both with the bracket 114 and with the socket pin 13, e.g. by welding, firmly connected.

In the embodiment of FIG. 3 instead of a single bracket on opposite sides of the socket pin two brackets 214 shortened approximately to half the width transversely to the socket pin, the free ends 215 of which in the same way as in the exemplary embodiment according to FIG. 1, are provided by means of bores 216 into which the wire loop is inserted by means of its ends 17 protrudes and is glued in it. As in the first exemplary embodiment, the sleeve can also extend with its ends 20 over the Ends 215 of the two brackets 214 extend.

The inner ends 221 of the two brackets 214 are along the locking pin; ι 13 bent against the scaffold tube 10 and with the Socket pin 13 welded over its length. Their free ends can also act as a stop to limit the insertion stroke of the socket pin 13 are used.

This design has the advantage that the bracket-side end of the socket pin 13 is completely exposed to the outside, so that hammer blows Immediately hit the socket pin 13 in the direction of the arrow χ.

If necessary, the ends bent inwards can also be used 221 of the bracket 214 similar to the case of the embodiment according to FIG. To connect the wire loop 18. The ends 221 would in this case - be dimensioned - approximately corresponding to the length of the sleeve-shaped projections 115 in FIG. 2 - while for the purpose of limitation of the insertion stroke, special stops can be provided on the socket pin 13, as is also the case for the exemplary embodiment according to Fig. 2 applies.

The socket pins themselves can be protected against rusting, e.g. by galvanizing or painting, be protected. Furthermore, it can be useful to make the temples conspicuously colored, e.g. to be provided with red paint so that people passing by, having been made aware of the hangers, are less likely to look at them hurt.

Socket pins according to the innovation can be used for both extendable and non-extendable loop lengths with the same loop length Scaffolding tubes, in particular supports, are used.
