Definitions
- the invention relates to a pull cord shortening for fire extinguishing devices according to the preamble of claim 1.
- a such is known from DE-A-1 559 693.
- Such shortening of the pulling rope is known, for example, to hold and secure the pull cables for kitchen hoods.
- the traction cables end in a switching device with one Shut-off valve for the extinguishing medium.
- the shut-off valve is opened and the extinguishing medium to the The source of the fire can occur.
- the invention is based on the object, a pull rope shortening to create according to the preamble of claim 1, which is simple and therefore inexpensive to manufacture can be.
- the shortening element consists of spring steel wire, preferably a single spring steel wire, the corresponding is wrapped.
- the eyelets are wound and dimensioned that the pull rope without difficulty and interruptions can be inserted. Because it is spring wire acts, this spring force can be used to to preload the shortening element itself.
- the shortening element is kept in the shortening element or tensioned position due to the thermal release Separating element, as it is for example in DE-OS 196 35 177 is described.
- This separation device proposed there consists of two interconnected parts that through the thermal release element, for example a Glass vials are held together in the securing position. If the thermal trip element is destroyed, disconnect the two parts to be joined and give the shortening element free, so that this is due to the tension in the pull rope and the residual stress "extended", namely if necessary up to a straight line of the pull rope. This ensures that the shut-off valve is opened so that the extinguishing medium by appropriate Lines reach the designated deletion points.
- the shortening element 1 shown in FIGS. 1 to 4 consists of a spring wire that is wound so that two End loops 2 and two deflection loops 3 arise.
- the traction cable 4 becomes the deflection eyelets 3 through the end eyelets 2 guided. It goes on without a break. It is straightforward recognizable that the deflection of the pull rope 4 to a Shortening leads. Form the ends of the shortening element 1 Hook into the thermal release device 5 is suspended from two parts to be joined. The parts to be joined are in the position shown in Fig. 1 by a thermal release element 6, in this case a glass barrel, held together. The shortening element 1 itself forms a spring, which holds the individual parts in position and in the final securing direction is biased. The tension in the pull rope 4 works as well.
- Fig. 4 shows a rotated by 90 ° thermal release device 5.
- the hooks on the Ends of the shortening element 1 are correspondingly different bent.
- FIGS. 5 and 6 shows a simpler one Geometry.
- the shortening element 11 is no longer a trapezoid, as in the embodiment of FIGS. 1 to 4, but an isosceles triangle. It is therefore only a deflection eyelet 11 is present.
- the end loops are designated by 12. Otherwise, this thermal release element acts just like that according to FIGS. 1 and 2.
- the deflection eyelet 11 can also be wound twice, if this to achieve certain geometric relationships or a certain spring characteristic is desired.
- the pull rope 4 is by means of connecting sleeves 13 connected to the pull rope of a kitchen hood device.
- the guide bracket 15 has a U-shaped cross section so that the shortening element 1 is held in position in which it is shown. A rotation around the axis of the pull rope is not possible.
