Den foreliggende opfindelse angår en tyverisikring til radiatorventil termostater, som angivet i krav l's indledning.The present invention relates to an anti-theft device for radiator valve thermostats, as set forth in the preamble of claim 1.
Sådanne tyveri sikringer er især nødvendige i sådanne tilfælde, hvor 5 termostaterne monteres i bygninger, der er offentligt tilgængelige. Derfor tilbyder praktisk taget alle fabrikanter af termostater sådanne termostater, som er forsynede med en sådan tyveri sikring til brug i offentlige bygninger.Such theft fuses are especially needed in such cases where the 5 thermostats are mounted in buildings that are publicly accessible. Therefore, virtually all thermostat manufacturers offer such thermostats, which are provided with such theft protection for use in public buildings.
10 Der kendes et stort antal udførelser af tyveri sikringer. Således kendes f.eks. fra det tyske offentliggørelsesskrift nr. 3.102.335 en tyveri sikring, ved hvilken den til fastgørelse af radiatorventil-termostaten til radiatorventilen tjenende omløbermøtrik omgives af to ringskål parter, der ved hjælp af en påskudt, lukket metalsik-15 ringsring fastholdes i deres stilling. Denne kendte tyverisikring er konstruktivt forholdsvis kompliceret og dyr og forringer desuden radiatortermostatens udseende.10 A large number of designs of theft fuses are known. Thus, e.g. from German Patent Specification No. 3,102,335, a theft fuse in which the inlet nut serving to secure the radiator valve thermostat to the radiator valve is surrounded by two ring bowl parts which are held in their position by means of a bolted closed metal fuse ring. This known anti-theft device is constructively relatively complicated and expensive and furthermore deteriorates the appearance of the radiator thermostat.
Formålet med opfindelsen er derfor at tilvejebringe en tyveri sik-20 ring, der er af særlig enkel og billig konstruktion og desuden ikke forringer termostatens udseende.The object of the invention is therefore to provide a theft fuse which is of particularly simple and inexpensive construction and furthermore does not impair the appearance of the thermostat.
Denne opgave løses ifølge opfindelsen ved hjælp af en tyverisikring med de i krav l's kendetegnende del angivne ejendommeligheder. Under 25 påskruning af omløbermøtrikken glider det fjedrende elements ombøjede ende på lignende måde som palen i en skraldemekanisme hen over tremmerne og snapper, efter at en tremme har passeret, ind i mellemrummet mellem denne og den følgende tremme, og låser derved omløbermøtrikken mod afskruning i den modsatte retning. Herved er 30 der opnået en enkel og billig tyveri sikring, der kun kræver ringe plads og derfor kan anbringes på en sådan måde, at den ikke er synlig og således ikke forringer radiatortermostatens udseende.This task is solved according to the invention by means of an anti-theft device with the characteristics specified in claim 1. Under 25 the screw nut, the bent end of the resilient member slides in a similar manner to the pile of a ratchet mechanism over the bar and snaps, after a bar has passed, into the gap between it and the following bar, thereby locking the bar nut against the screw in the bar. opposite direction. Hereby, a simple and inexpensive theft fuse is obtained which requires little space and therefore can be arranged in such a way that it is not visible and thus does not impair the appearance of the radiator thermostat.
Skraldeprincippet som tyveri sikring er ganske vist kendt fra tysk 35 offentliggørelsesskrift nr. 2.750.956. Ved denne udførelse forbindes radiatortermostaten imidlertid ikke med radiatorventilen ved hjælp af en omløbermøtrik. Tværtimod anvendes der her en særlig konstruktion, ved hvilken en ringformet skive med i det mindste en fra skiven udragende klo er drejefast forbundet med en rørstuds, og ved 2The rubbish principle as a theft protection is admittedly known from German 35 Publication No. 2,750,956. However, in this embodiment, the radiator thermostat is not connected to the radiator valve by means of a bypass nut. On the contrary, a special structure is used here in which an annular disc with at least one claw protruding from the disc is pivotally connected to a pipe nozzle, and at 2

hvilken termostathuset har~en med en fortanding forsynet ring. Ved påskruning af det med et indvendigt gevind forsynede termostathus på rørstudsen kommer kloen i indgreb med fortandingen og forhindrer dermed en fjernelse af termostathuset fra rørstudsen. Sammenlignet 5 med denne kendte konstruktion har konstruktionen ifølge den foreliggende opfindelse den fordel, at enhver i handelen sædvanlig radiatortermostat uden væsentlige modifikationer kan forsynes med en tyverisikring. Ifølge opfindelsen kræves kun en modifikation af omløbermøtri kken.which thermostat housing has a toothed ring. By tightening the internally threaded thermostatic housing on the pipe connector, the claw engages with the tooth and thus prevents removal of the thermostat housing from the pipe connector. Compared to this known construction, the construction of the present invention has the advantage that any commercially available radiator thermostat can be provided with a theft protection without significant modifications. According to the invention, only a modification of the bypass nut is required.

Endvidere kendes fra US-A-1.722.541 og FR-A-961.591 en fjederring, der er indlagt i en møtrik og med en ombukket ende indgriber i en længdenot i en gevindbolt og med sin anden ende fjedrende snapper ind i en skraldefortånding i møtrikken og dermed låser møtrikken mod 15 afskruning. En lignende løsning kendes fra FR-A-591.256. Fremstillingen af en sådan indvendig skraldefortanding er imidlertid kompliceret og dyr.Further, from US-A-1,722,541 and FR-A-961,591, a spring ring is inserted which is inserted into a nut and with a bent end engages a longitudinal groove in a threaded bolt and with its other end resiliently snaps into a ratchet tooth in the nut. thus locking the nut against 15 screw-offs. A similar solution is known from FR-A-591,256. However, the preparation of such internal ratchet teeth is complicated and expensive.
Opfindelsen forklares nærmere i det følgende under henvisning til 20 udførelseseksempler, der er anskuel iggjort på tegningen. På tegningen viser:The invention will be explained in more detail below with reference to 20 exemplary embodiments illustrated in the drawings. In the drawing:

Ib et snit gennem radiatortermostaten i fig. 1 til anskueliggørelse af et første udførelseseksempel for opfindelsen, fig. 1c et andet snit gennem fig. 1 til anskueliggørelse af et andet udførelseseksempel for opfindelsen, og 30 fig. Id et tredje snit gennem fig. 1 til anskueliggørelse af et tredje udføre!seseksempel for opfindelsen.FIG. leave a radiator thermostat with rotating nut, FIG. 1b is a section through the radiator thermostat of FIG. 1 to illustrate a first embodiment of the invention; FIG. 1c shows another section through FIG. 1 to illustrate another embodiment of the invention, and FIG. In a third section through FIG. 1 to illustrate a third embodiment of the invention.
Ifølge fig. 1 har et radiatortermostathus 5 en med akseparallelle 35 slidser 7 og en udadvendende ringkrave 8 forsynet bøsningformet husdel 9..Husdel en 9 består ligesom termostathuset 5 sædvanligvis af formstof, således at tremmer 4, der er dannet mellem slidserne 7, er eftergivelige og tillader påskydning af en omløbermøtrik 1, der er forsynet med en indadvendende, ringformet modkrave 10.According to FIG. 1, a radiator thermostat housing 5 has a sleeve 7 with axial parallel 35 and an outward annular collar 8 housing-shaped housing part 9. Housing part 9, like the thermostat housing 5, is usually made of plastic, so that bars 4 formed between the slots 7 are resilient and allow sliding. of a screw nut 1 provided with an inward-facing annular counter-collar 10.

Omløbermøtrikken 1 griber med sit indvendige gevind 11 ind over en med radiatorventilen forsynet rørstuds med udvendigt gevind, hvilket ikke er nærmere vist.The bypass nut 1 engages its internal thread 11 over an outer threaded pipe nozzle provided with the radiator valve, which is not shown further.
5 I omløbermøtrikken 1 er et fjedrende element 2 anbragt aksi alt uforskydeligt mellem ringkraven 8 og modringkraven 10. Det fjedrende element 2 består, som vist i fig. Ib, af en tråd, der over en væsentlig del af den indvendige omkreds ligger an mod omløbermøtrikken 1 og ved den ene ende er ombøjet til dannelse af en fjeder-10 tunge 3 og ved den anden ende 12 er vinkelret ombukket og ført ind i en radialt rettet not 13 i omløbermøtrikken, således at den er sikret mod drejning. Som det ses i fig. 1, glider fjedertungerne 3 ved påskruning af omløbermøtrikken 1 hen over tremmerne 4. En afskruning af omløbermøtrikken 1 forhindres ved, at fjedertungerne 3 15 griber ind bag den set i omløbermøtrikkens påskruningsretning bageste side af tremmerne 4.5 In the rotary nut 1, a resilient member 2 is disposed axially all slidably between the ring collar 8 and the collar collar 10. The resilient element 2 consists, as shown in FIG. 1b, of a thread which, over a substantial portion of the inner circumference, abuts the nut of nut 1 and at one end is bent to form a spring tongue 3 and at the other end 12 is perpendicularly folded into a radially aligned groove 13 in the nut so that it is secured against rotation. As seen in FIG. 1, the spring tongs 3 slip by the screw nut 1 over the barbs 4. A screw-off of the nut 1 is prevented by the spring tongues 3 15 engaging behind it seen in the rear direction of the nut nut 4 of the bar 4.
I fig. lc er det af fjedertråd bestående fjedrende element 2 lagt ind i en indre omkredsnot 14 i omløbermøtrikken 1, og sikring mod 20 drejning er opnået ved en vinkelret ombukning og indlægning af den ene ende 12 i en akseparallel not 15.In FIG. 1c, the resilient spring element 2 is inserted into an inner circumferential groove 14 in the circumferential nut 1, and protection against 20 turns is obtained by a perpendicular folding and insertion of one end 12 into an axis parallel groove 15.
I fig. Id består det fjedrende element 2 af en fjederplade, fra hvilken flere fjedertunger 6,6',6" og 6"' er udbøjede og har en 25 afstand fra hinanden svarende til tremmerne 4's afstand fra hinanden. Fjederpladen 2's fastgørelsesende 12 er vinkelret ombukket og indført i en akseparallel slids 16 i omløbermøtrikken 1.In FIG. Id, the resilient member 2 consists of a spring plate from which several spring tongues 6,6 ', 6 "and 6"' are bent and have a distance of 25 from each other corresponding to the distance of the bars 4 from one another. The fixing end 12 of the spring plate 2 is perpendicularly folded and inserted into an axis parallel slot 16 in the nut 1.
