Abstract

An indicator measuring the relative thermal output of heating bodies by evaporation of a fluid has an elongated housing holding a glass tube contg. the measurement fluid. A fixing screw (10) projecting from the lower housing holds a blocking yoke (12) and a lead sealed lower cover protects the screw head. Access to the screw shaft is prevented by using a specially shaped yoke enclosing the end of the shaft. The blocking yoke (12) has hollow projections (41, 42) coaxial with its inner thread which cover the end (10A) of the shaft of the fixing screw either side of the yoke. The hollow projections are tubes welded to the yoke. The blocking yoke is intended to prevent unauthorised dismantling of the equipment by turning the screw shaft.

Description

Anzeigegerät zur Bestimmung der Wärmeabgabe Display device for determining the heat output

von Heizkörpern, sog. Heizkostenverteiler Zusatz zu Patent ....(P 28 51 122.0) Gegenstand des Hauptpatents (P 28 51 122.0) ist ein Anzeigegerät zur Bestimmung der relativen Wärmeabgabe von Heizkörpern durch Verdunstung einer Meßflüssigkeit, sogenannter Heizkostenverteiler, mit einem länglichen, ein die Meßflüssigkeit enthaltendes Glasröhrchen aufnehmenden Gehäuse, mindestens einer aus der Rückwand des Gehäuse-Unterteils herausragenden Befestigungsschraube für einen Sperrbügel, und mit einem mit dem Gehäuse-Unterteil verbindbaren Deckel, der zur Sicherung des innerhalb des geschlossenen Gehäuses liegenden Kopfes der Schraube mit dem Gehäuse-Unterteil verplombt werden kann, wobei als zusätzliche Sicherung gegen unbefugtes Abmontieren des Gerätes eine am Schraubenkopf angreifende Schraubensicherung innerhalb des verplombten Gehäuses vorgesehen ist. of radiators, so-called heat cost allocators, addendum to patent ... (P 28 51 122.0) The subject of the main patent (P 28 51 122.0) is a display device for Determination of the relative heat emission from radiators through evaporation of a measuring liquid, So-called heat cost allocator, with an elongated one, one containing the measuring fluid Glass tube receiving housing, at least one from the rear wall of the housing lower part protruding fastening screw for a locking bracket, and with one with the Housing lower part connectable cover, which is used to secure the inside of the closed The head of the screw lying on the housing must be sealed with the lower part of the housing can, with an additional security against unauthorized dismantling of the device Screw locking acting on the screw head within the sealed housing is provided.

Als weitere Lösung des dem Hauptpatent ......... zugrundeliegenden Problems wird vorgeschlagen, daß der Sperrbügel koaxial zu seinem Innengewinde mit mindestens einem hohlkörperartigen Fortsatz zur Abdeckung des Endes des Schraubenschaftes der Befestigungsschraube versehen ist. Um auch einen zum Heizkörper hinweisenden Bereich des Schraubenschaftes abzudecken, empfehlen sich solche Fortsätze zu beiden Seiten des Innengewindes. Die Fortsätze bestehen zweckmässig aus angeschweißten Hülsen, jedoch kann auch der Sperrbügel als Ganzes höhlkörperartig gestaltet sein.As a further solution to the ......... on which the main patent is based Problem is proposed that the locking bracket coaxial with its internal thread at least one hollow body-like extension to cover the end of the screw shaft the fastening screw is provided. To include a radiator that points to the radiator To cover the area of the screw shaft, such extensions are recommended for both Sides of the internal thread. The extensions expediently consist of welded-on Sleeves, but the locking bracket as a whole can also be designed like a hollow body.

Durch die Erfindung wird die Möglichkeit des Zugriffes am Schraubenschaft durch eine spezielle Ausbildung des Sperrbügels selbst verhindert, indem dieser das Ende des Schraubenschaftes umhüllt, an dem bisher durch Ansetzen einer Drehvorrichtung oder dergl. die Befestigungsschraube gelöst und das GErät unbefugt abmontiert werden konnte.The invention makes it possible to access the screw shaft prevented by a special design of the locking bracket itself by this enveloped the end of the screw shaft, on which previously by attaching a rotating device or the like. The fastening screw is loosened and the device can be removed without authorization could.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung ein auf einem Schraubenschaft 10 aufgeschraubter Sperrbügel 12 aus Stahlblech dargestellt, an dem zu beiden Seiten seines Innengewindes Hülsen 41 und 42 koaxial aufgeschweißt sind Diese Hülsen umhüllen das Ende 10a des Schraubenschaftes, wobei es hauptsächlich auf das freie, von der Hülse 41 abgedeckte Ende ankommt, das meist über den Sperrbügel 12 hinausragt. LeerseiteIn the drawing is an embodiment of the invention A locking bracket 12 made of sheet steel screwed onto a screw shaft 10 is shown, on which sleeves 41 and 42 are welded coaxially on both sides of its internal thread These sleeves envelop the end 10a of the screw shank, whereby it is mainly on the free, covered by the sleeve 41 end, which usually over the locking bracket 12 protrudes.
