Abstract

Hinge device with locking function for drain and septic tank cover and designed to lock the cover 16a to a drain ring 17 or the like, comprising a T-pipe 2, fixed to the cover 16a and rotatable on an upright column 3, the T- pipe 2 being locked to prevent turning by way of an eccentric 1, which can be brought out of the locking position by means of a key 8, with a shaft length L, which is considerably larger than the radius R of the eccentric, in order to provide sufficient leverage to shift the T-pipe 2 on the column 3, using considerably reduced force.

Description

15 20 25 30 35 504 370 2 anordnat den däröver passande ena skänkeln av ett T-rör 2, som vid undre delen av samma skänkel har ett spärrspár ll, vilket genom samverkan med ett däri ingripande spärrstift 4 anordnat på stolpen 3 kan förhindra att T-röret 2 vrides kring stolpen. 504 370 2 arranged the overlying one leg of a T-tube 2, which at the lower part of the same leg has a locking groove 11, which by cooperation with an engaging locking pin 4 arranged on the post 3 can prevent T -tube 2 is rotated around the post.

Som framgår av Fig. 2 och 3 finns i de till stolpen 3 tvärgående delarna av T-röret 2 en roterbar excenter 1, i ena änden försedd med ett nyckelgrepp 5, medan excentern 1 genom ett vid den andra änden anordnat stift 9 är begränsat roterbar i T-röret. Diametralt motsatt en excenterurtagning i excentern 1 finns anordnat en mindre urtagning 16, vars funktion kommer att förklaras senare. Med hjälp av ett periferiellet spår 6 inne i T-rörets kring stolpen anordnade del och en i en kanal i stolpen anordnad kula 7, som förspännes i riktning utåt av en fjäder 12, är T-röret 2 spärrat mot axiell rörelse utefter stolpen.As can be seen from Figs. 2 and 3, in the parts of the T-tube 2 transverse to the post 3 there is a rotatable eccentric 1, provided at one end with a key grip 5, while the eccentric 1 is limited by a pin 9 arranged at the other end. in the T-tube. Diametrically opposite an eccentric recess in the eccentric 1, a smaller recess 16 is arranged, the function of which will be explained later. By means of a peripheral groove 6 inside the part of the T-tube arranged around the post and a ball 7 arranged in a channel in the post, which is biased in the outward direction by a spring 12, the T-tube 2 is locked against axial movement along the post.

Med en nyckel 8, som passar i nyckelgreppet 5 kan excentern 1 vridas i T-rörets horisontella del, varvid excenter- urtagningen medför att T-rörets kring stolpen anordnade del lyftes efter att motståndet från den fjäderbelastade kulan 7 övervunnits. Samtidigt kommer härvid spärrstiftet 4 att föras ur ingrepp med spärrspáret ll, varefter det är möjligt att vrida T-röret 2 och det därtill fästa locket 16a kring stolpen 3.With a key 8, which fits in the key grip 5, the eccentric 1 can be rotated in the horizontal part of the T-tube, the eccentric recess causing the part of the T-tube arranged around the post to be lifted after the resistance from the spring-loaded ball 7 has been overcome. At the same time, the locking pin 4 will be disengaged from the locking groove 11, after which it is possible to turn the T-tube 2 and the cover 16a attached thereto around the post 3.

Utföringsexemplet enligt Fig. 4 skiljer sig från det tidigare redovisade genom att i överdelen av stolpen finns ett cylindriskt urtag i vilket är axiellt rörlig en av en fjäder 19 mot làsläge förspänd plunge 18.The exemplary embodiment according to Fig. 4 differs from that previously reported in that in the upper part of the post there is a cylindrical recess in which a plunger 18 of a spring 19 biased towards the locking position is axially movable.

Läsning i utgångsläge enligt Fig. 2 och Fig. 4.Reading in initial position according to Fig. 2 and Fig. 4.

Excenterns 1 uppläge medför att stolpen 3 i inskjutet läge med spärrstiftet 4 spärrar mot sidovridning av T-rör 2 i urtag 11, samtidigt som vertikalrörelse hindras av att 10 15 2504 370 3 kulan/kulorna 7 är inpressade i spår 6, resp. genom fjäder- tryck 12 eller genom den fjäderbelastade plungen 18.The position of the eccentric 1 means that the post 3 in the retracted position with the locking pin 4 blocks against lateral rotation of T-tube 2 in recess 11, at the same time as vertical movement is prevented by the ball (s) 7 being pressed into groove 6, resp. by spring pressure 12 or by the spring-loaded plunger 18.

Frigörande enligt Fig. 3.Release according to Fig. 3.

Spärrorganen 4, 11 lösgjorda genom att T-röret 2 förskjutits uppåt då man med nyckeln 8 vridit excentern ett halvt varv så som tillåtes av stiftet 9. I detta läge kan locket l6a svängas åt sidan då T-röret 2 frigjort från spärrstiftet 4 fungerar som gångjärn runt stolpen 3.The locking means 4, 11 are loosened by displacing the T-tube 2 upwards when the eccentric is turned half a turn with the key 8 as permitted by the pin 9. In this position the lid 16a can be swung to the side when the T-tube 2 released from the locking pin 4 functions as hinges around the post 3.

Excenterns högsta punkt planas något 16 för att ge självlåsning mot stolpens 3 överända. Infästning av stolpen 3 består av fästplatta utformad med två öron 13 och en genom stolpen 3 tvärgående axel 14, samt justerskruvar 15 i 90° förhållande till och på ömse sidor om nämnda axel 14.The highest point of the eccentric is leveled somewhat 16 to provide self-locking against the upper end of the post 3. Fastening of the post 3 consists of a mounting plate formed with two ears 13 and a shaft 14 transverse through the post 3, and adjusting screws 15 in 90 ° relation to and on either side of said shaft 14.
