Description

.7v1o1as-s 2 jar en fjärrvärmeoperatör fjärrvärmecentralnyckeln och nyckeln i skåpet. Skâpen uppvisar emellertid en hög inbrottsfrekvens. I fall av inbrott mäste ingângslåset för fastigheten bytas ut. Kostnads- konsekvenserna är uppenbara. .7v1o1as-s 2 a district heating operator the district heating central key and the key in the cabinet. However, the cabinets have a high burglary frequency. In case due to burglary, the entrance lock for the property must be replaced. Cost the consequences are obvious.

Användningen av skåp med ingângsnyckeln till fastigheterna kan elimineras genom att i ingângsdörren montera ett låsaggregat med tvâ låscylindrar, som var för sig kan manövrera en regelkolv via en kugghjulsenhet. _ Nackdelen med sådana kända lâsaggregat är att de inte kan ut- nyttja ett redan befintligt lâs i en dörr. , Ändamålet med föreliggande uppfinning är att åstadkomma en lås- 'anordning av sistnämnda typ, vilken utnyttjar en befintlig låsanord- ning i en dörr, varvid en avsevärd kostnadsbesparing göres i för- hållande till tidigare känd teknik.The use of cabinets with the entrance key to the properties can be eliminated by mounting a locking unit in the entrance door with two locking cylinders, each of which can operate a control piston via a gear unit. _ The disadvantage of such known locking assemblies is that they cannot be use an existing lock in a door. , The object of the present invention is to provide a locking device of the latter type, which utilizes an existing locking device. in a door, whereby a considerable cost saving is made in adhering to prior art.

Detta ändamål uppnås med en låsanordning, vars särdrag fram- går av efterföljande patentkravs kännetecknande del.This object is achieved with a locking device, the features of which is of the characterizing part of the appended claims.

Uppfinningen kommer att beskrivas närmare nedan med ett ut- föringsexempel under hänvisning till medföljande ritningar.The invention will be described in more detail below with a examples with reference to the accompanying drawings.

Fig l visar från sidan och schematiskt en i en dörr monterad lâsanordning enligt uppfinningen. Fig 2 visar i planvy delar av lâsanordningen i fig l.Fig. 1 shows from the side and schematically one mounted in a door locking device according to the invention. Fig. 2 shows in plan view parts of the locking device in fig.

Den i fig l visade läsanordningen har en första lâscylinder 1, en andra láscylinder 2, en regelkolv 3, ett vred 4 och ett skyltbe- slag 5. Till låscylindrarna l och 2 hör nycklar 6 resp 7. Låsanord- ningen är monterad i en dörr 8. Nyckeln 6 passar ej till lâscylin- dern 2 och nyckeln 7 ej till lâscylindern l. Regelkolven 3 är en- ligt uppfinningen manövrerbar medelst nyckeln 6, nyckeln 7 och vre- det 4 var för sig. _ En icke visad axel är med en frigång förbunden med den första lâscylinderns 1 innercylinder. Till axeln är vidare reglerkolven 3 kopplad. Dessutom är vredet 4 stelt fäst pâ denna axel.The reading device shown in Fig. 1 has a first locking cylinder 1, a second lock cylinder 2, a control piston 3, a knob 4 and a plate type 5. The lock cylinders 1 and 2 include keys 6 and 7 respectively. is mounted in a door 8. The key 6 does not fit the lock cylinder 2 and the key 7 not to the locking cylinder 1. The control piston 3 is according to the invention can be operated by means of the key 6, the key 7 and the the 4 separately. _ A shaft (not shown) is connected with a clearance to the first locking cylinder 1 inner cylinder. To the shaft is further the control piston 3 connected. In addition, the knob 4 is rigidly attached to this shaft.

I den i fig 2 visade vyn av skyltbeslaget 5 är detta sett i nycklarnas instíckningsriktning.In the view of the sign fitting 5 shown in Fig. 2, this is seen in insertion direction of the keys.

Skyltbeslaget 5 har rörliga organ i form av ett första kugg- hjul 34, ett andra kugghjul 35-och ett tredje kugghjul 36. Detta se- nare är anordnat i kuggingrepp med det första kugghjulet 34. Det andra kugghjulet 35 är medelst ett medbringärhâl 37 utan någon fri- gång förbundet med den andra låscylinderns 2 rörliga innercylinder.The plate fitting 5 has movable means in the form of a first tooth wheel 34, a second gear 35 and a third gear 36. This nare is arranged in gear engagement with the first gear 34. It the second gear 35 is by means of a carrier bore 37 without any release connected to the movable inner cylinder of the second locking cylinder 2.

Det andra kugghjulet har en ofullständig kuggkrans, som bildar enThe second gear has an incomplete gear ring, which forms one

Claims

Such a recess 38 in the second gear 35 that the third gear 36 is not in gear engagement with the second gear 35, when the movable inner cylinder of the second locking cylinder 2 is in its locked normal position and that the incomplete gear ring brought into gear engagement with the third gear 36, when the movable inner cylinder 2 of the second locking cylinder 2 is rotated from its normal position. A clearance is thus arranged between the second gear 35 and the third gear 36. The first gear 34 is connected by means of a carrier hole 39 without any clearance to the above-mentioned shaft, not shown. The two clearances are such that by means of only one of the keys 6, 7 the inner cylinder of the associated locking cylinder can be detached from its locked normal position and maneuver the bolt, while the inner cylinder of the locking cylinder which cannot be maneuvered by this key remains in its locked normal position. The clearances are further such that the bolt can be operated by means of the knob 4, while the inner cylinders of the two locking cylinders remain in their locked normal positions. Each of the carrier holes 37 and 39 in the embodiment of Fig. 2 has a cross-sectional shape composed of a square and a rectangle, the center point of which corresponds to the center point of the square and the longitudinal centerline of which extends along one of the diagonals of the square. The long side of the rectangle is about twice as long as the side of the square. CLAIMS Claiming device with a first locking cylinder (1), which is freely connected to a shaft, which is coupled to a control piston (3), a first gear (34) mounted on the shaft and a second locking cylinder (2), which is connected to a second gear (35), characterized in that an intermediate gear (36) is connected between the first (34) and the second (35) gear; that the gear ring of the second gear (35) has a recess (38) to form a clearance between the second gear and the intermediate gear, when the second locking cylinder (2) is in the locked position, whereby the control piston (3) is operable by actuating either of the lock cylinders (1, 2); and that the gears (34, 35, 36) are mounted on a plate fitting (5), which can be connected to an existing locking unit 1 a door (8).
