DE20317251U1 - Personnel safety device has runner unit movable on steel cable and with preformed sheet metal pieces which in lower section have elongated hole extending at right angles to axis - Google Patents

Abstract

The personnel safety device has a horizontally extending stainless steel cable (6) along which moves a runner upon which the personnel are secured by a carabine hook (5). The runner unit has at least two pieces of preformed sheet metal (2) which in their lower section have an elongated hole extending at right angles to the axis and dimensioned so that in the unlocked state they open the slide piece halves (1) wide enough for the runner unit to be pulled down or pushed up from the cable at an angle of 90 deg to the cable axis. In the locked state the two slide piece halves are opened only wide enough so that the runner unit can move over the cable and cable holder (7).

Description

TECHNICAL TERRITORY

The invention relates to fall protection for everyone Civil engineering applications according to DIN 4426, in which after its creation, personnel, for maintenance, care purposes and maintenance, in areas where there is a risk of falling have to and where a horizontal rope, transverse to the direction of fall running, can be excited.

STATE OF TECHNOLOGY

There are various fall protection devices, of the type mentioned above, which deals with personal protection deal with those already in a previous application, under the file number Az .: 298 11 100.8.

PRESENTATION THE INVENTION

Based on the known state The invention is based on the object of the invention, a improved, more filigree, more beautiful and less expensive To create fall protection.

This invention is through the features of claims Given 1 to 6.

The fall protection according to the invention exists from 3 main components,

• - the runner unit ( 1 / 2 / 6 / 7 )
• - the 6mm thick stainless steel rope (pos. 6 ) ( 1 / 8.2 )
• - the rope holders (pos. 7 ) ( 1 / 8.1 / 8.2 )

The rope holder (pos. 7 ) can be connected to the building either directly or via posts (not shown).

The use of the only 6mm thick rope (pos. 6 ), allows a more delicate construction and thus, an architectural, unobtrusive appearance, which in turn contributes to the better overall appearance of the building.

Due to the use of the 6mm thick rope (Pos. 6 ) and the resulting lower weight, further advantages are achieved:

• - less Material costs (rope costs)
• - less Transport costs due to lower weight
• - less Assembly costs, due to better handling options (transport, on site, on the ground and up, to the place of attachment)

The runner unit ( 1 / 2 / 6 / 7 ) has the following advantages over the prior art:

• - cheaper manufacturing
• - no lost parts
• - Fast hanging in and out of the rope (pos. 6 )
• - Runner is able to follow any cable direction

DESCRIPTION THE DRAWINGS

1 Runner unit, attached to the stationary safety rope (item 6 ), in operational locking, by carabiner hook (pos. 5 ) shows how the runner unit according to the invention, like it, over the carabiner hook (item 5 ), with the mobile rope, the personnel, and like the runner unit, on which, on the structure, via the rope holder (item 7 ), fixed 6mm safety rope (pos. 6 ), slidable, mounted. The shaped sheets (pos. 2 ) are, as a rule, about 45 ° -90 ° from the rope axis (pos. 6 ), swung away and locked. Swinging open, the shaped sheets (Pos. 2 ), is by the carabiner hook (Pos. 5 ), prevented. The shaped sheets (pos. 2 ), without stops, around the taper axis of the two halves of the slide (item 1 ), and any swivel angle to the rope (pos. 6 ), take in. At the same time, the runner, with the exception of the rope holders (item 7 ) to rotate around the rope axis. The runner is thus able to adjust to the position of any direction, a force caused by the, on the carabiner hook (Pos. 5 ), attached, mobile personal safety rope.
