Definitions
- the invention relates to a height adjustable in steps Hydrants as above or below floor hydrants with one connected to an underground water pipe Inlet arch or a vertical inlet and a attached, two-part leading up to about the earth's surface Riser pipe according to the generic term of the independent Claim 1.
- the invention further relates to a predetermined breaking point on the above-ground hydrant using predetermined breaking screws according to the preamble of the independent Claim 7.
- the invention relates to a when running as a hydrant on the Riser-mounted, above-ground attachment pipe with Hose connections according to the generic term of the independent Claim 9.
- Hydrants are directly connected to the local water supply network connected and serve as water withdrawal point, especially for fire fighting, but also for the Street cleaning, for water supply to short construction sites and for irrigation purposes.
- hydrants When operating the pipe network hydrants are used as a ventilation point and as a valve for periodic Power conditioners.
- the main purpose of hydrants is to extract water for firefighting applications, requires the fastest possible and reliable availability of large quantities of water. Hydrants must therefore be found immediately at any time be quickly and easily accessible and also after Decades of downtime and longer periods of non-use guaranteed to function safely.
- hydrants which are necessary by the tens of thousands, production costs as low as possible and cause maintenance expenses.
- the underground hydrant On the one hand the underground hydrant; this is a closed with a lid Connection below the street level, the Water withdrawal via a temporary standpipe or directly via a hose connection provided on the riser pipe he follows.
- the above-ground hydrant in which one Column - the so-called top tube - protrudes from the ground; water is drawn from hose connections here, which are provided at the top of the top tube.
- DE-GM 71 06 456 proposes that Predetermined breaking point by means of the attachment pipe and the riser pipe correspondingly weakly dimensioned brass screws to accomplish. When starting, these screws should break and thus kink the above-ground hydrant without other major damages arise. With this solution was one is also not satisfied in practice. Also weather and pollution-related influences led to an indefinite one Response range of the screws. Part of it was the necessary minimum stability over time is questionable fell below, on the other hand the screws broke a collision is not as desired.
- DE-OS 33 18 438 is a different type of predetermined breaking connection reveals where to go under that in a hole a flange seated screw head a shear bush provides.
- the shearer's shoulder pointing inwards reaches under the screw head; the center bar of the shear box surrounds the screw head on the side, and one on the outside pointing shoulder of the shear bush rests on the edge the flange bore.
- the Shear box at its weakest point - in the center bar and thus the screw head through the then too large Flange bore slips through.
- the disadvantage here is that one is special and made from a special alloy molded component needed.
- the known hydrants can be summarized none of them can be rated as optimal.
- the invention has therefore taken on the task of making a multiple improvement
- the requirements should be met over different dimensions of the hose connections and their right / left distribution can be implemented in a simplified manner his.

Place on the hose connectors the users of the above ground hydrant on the fire hose arranged complementary coupling pieces. With the various hose connectors, fitting caps the hose connectors when not in use closed and thus protected. Depending on the posed An above-ground hydrant can therefore meet requirements the required hose connectors.
- the hydrant according to the invention provides compared to the State of the art has the following advantages.
- the first and also subsequent height adjustment can be done on uncomplicated and be done safely. Even after decades Changing the height is not difficult.
- the holder of the in the standpipe jacket partially and telescopically seated riser is absolutely safe against accidental Adjust in height, automatic pressing out by the water pressure and any twisting. A permanent tightness and inevitably correct Assembly is guaranteed.
- the designed breaking point responds when a maximum permissible force on the top tube is exceeded in the event of a collision, so that larger Damage to the underground hydrant or to the underground Water pipe can be avoided.
- a correspondingly massive one Impact the hammer screws tear off as intended, the top tube bends and the spindle extension falls from the spindle nut. In many cases, this will be a more extensive one Prevents destruction and water loss and the Repair costs kept low. On the other hand, they meet hammer screws used their clamping function for decades.
