Abstract

The protective device for sprinklers (1) against damage by external influences has preferably commercially available pipe fittings for connecting to pipes (4) and to the sprinkler, especially so-called bends and T-pieces (2), which are combined with additional specifically formed shielding components (1.0), or are equipped with barrier contours (1.2) at a specific position with specific dimensioning to the extent that as a functioning unit they are suitable and available for the compensation of external kinetic energy.

Description

Technical area

The The invention relates to a protection device for sprinklers of fire extinguishing systems against damage due to accidental (accidental) trigger contacts in the normal course of action in commercial buildings / facilities and facilities equipped with "sprinkler protection".

task the device according to the invention is damage prevention due to water damage, which are indispensable if a sprinkler is extremely sensitive to impact contacts in the passive state by "human Negligence "or malfunction of devices (especially forklift) is damaged.

such Damage risks are relatively high and may be due to the protective device according to the invention in a simple, rational form significantly reduced-if necessary be eliminated.

Especially high relevant There are risks of damage in sprinkler-protected storage racks in the commercial sector Range, the manual or with forklifts often in short temporal Intervals "be.- or unloaded ".

Presentation of the invention

task The invention is the shield of the intended positioned Sprinklers against kinetic energy, which in case of improper handling, z. Of goods, furniture, Tools etc. on the sprinkler - especially that, the fire water restrained, Glass barrel, acts.

Of the The basic idea is a statically stable protective device, on the one hand compliant with the relevant Criteria of fire protection corresponds, as far as the amounts of water and their distribution (spraying behavior) not impaired - on the other hand makes effective resistance to "foreign body contact" available.

Of the technical structure of the protective device is as simple as it is rational, because with simple extra Components or additional Contours on conventional components is produced an effective problem solution and available.

Supplementary explanations result from the following description of an embodiment.

embodiment

in the Practical use are the proposals according to the invention in particular for sprinkler protection suitable for storage shelves.

In In this area of application, the sprinklers comply with the relevant regulations the property insurer between individual shelves or in each case in the Center of individual shelves positioned.

Out This situation implies that the risk area for damages the sprinkler by abutting contacts clearly "from front ", ie from the shelf front (insertion opening shelf) to the Position of the sprinkler is defined.

According to these facts, the preventive measures according to the invention are in the form of a protective device ( I / Ia ) and explained in the following example:
A sprinkler to be placed in the middle of a shelf ( 1 ) is passed through a pipe molding ("T-piece") ( 2 ) to the pipe network ( 4 ) that the sprinkler ( 1 ) is positioned offset by 90 ° to the axis of the connecting pipe. In the pipe connection ( 4 ) opposite sleeve of the tee is the shielding component ( 1.0 ), but releasably positioned.

The shielding component ( 1.0 ) consists of a molded part with threaded connection ( 1.1 ) and a blocking contour ( 1.2 ), which are fixed or detachable with the molded part ( 1.1 ) connected is.

The blocking contour ( 1.2 ) runs vertically parallel to the axis of the sprinkler ( 1 ) but at least until Lower edge of the sprinkler ( 1 ). In rack insertion direction is the sprinkler ( 1 ) basically in the "shadow" of the protective device ( I / Ia ) or their blocking contour ( 1.2 ).

In an optional version, three blocking contours ( 1.5 ) provided fixedly with the thread forming part ( 1.1 ) - insofar as the functional unit shielding component ( 1.0 ) produce ( II / IIa ). This design extends the protection area to the right or left of the center of the sprinkler ( 1 ).

The Basic principle of this problem solution is in alternative versions functionally equivalent extremely rational applicable.

To the Example:

The pipe molding "T-piece" ( 2 ) is on the outside of the housing in the center of the vertical middle sleeve of the pipe connection ( 4 ) - in which the sprinkler ( 1 ) is positioned - with a locking contour ( 2.0 ), which forms the housing of the T-piece ( 2 ) completely or partially covers and the free overhanging end of this locking contour ( 2.0 ) of the length of the specifically used sprinkler ( 1 ) corresponds ( III / IIIa ).

In principle, similar to the aforementioned embodiment option, the pipe molding "bow" ( 3 ) with a blocking contour ( 2.1 ) be formed ( IV / IVa ). Here, the locking contour firmly connected to the housing ( 2.1 ) over the pipe bend outer housing (large radius) and extends with the free end to at least lower edge of the specific sprinkler used ( 1 ).

The vertical on the housings of the pipe fittings ( 1 () 2 ) provided blocking contours ( 2.0 () 2.1 ) can with additional contours ( 2.2 ) be formed. The latter are horizontal in the lower free area of the blocking contours - about the middle of sprinklers ( 1 ), Regionally or advantageously circular the sprinkler ( 1 ), arranged.

The blocking contours ( 2.0 () 2.1 ) are preferably part of the manufacturing process of the pipe parts ( 2 () 3 ) - In this respect in relation to the efficiency an inexpensive problem solution.
