I kapselens 2 etter tegningen i dens høyre In capsule 2 following the drawing to its right

vegg, som er motsatt den ved hvilken låsestemplet 1 er beliggende, er lagret den ene ende av en-trykkskruefjær 8, hvori er inn-passet det ene endeparti av det ledd 9 som stikker ut fra fjærens motsatte ende og som nær ved sin ytterende er forsynt med tapper 10 lagret i spor 11 og glidbare langs disse. Disse spor 11 er anordnet slik at tappenes 10 avstand fra låsestemplets dreieaksel 3 ved låsestemplets 1 dreining til sperrestilling økes. Fjærens dreiemo-ment vil således ikke forandre seg med dens spenning. Videre blir overgangen fra fristilling til låsestilling eller omvendt myk, da tappen ved dette moment er lengst nede i sporet 11 og således nær ved akse-len 3. Leddets 9 forbindelsestapper 10 på låsestemplet 1 er i forhold til dettes svingeaksel 3 således anordnet at de ved dørens stenge- og åpningsbevegelse passerer en kraftlinje fra fjæren 8 mot svingeakselen, hvorved fjærtrykket foruten å bidra ved dørens stengebevegelse til å svinge låsestemplet til sperrestilling også svinger låsestemplet 1 til sin endelige fristilling når tappene 10 under dørens åpningsbevegelse passerer den nevnte kraftlinje. Låsestemplet 1 stoppes i full åpningsstilling dels ved hjelp av låsestemplets indre anslag mot innsiden av kapselen 2 og dels ved hjelp av leddets 9 anslag mot den samme innside av kapselens 2 øvre vegg. Den mot døren åpne kapsel 2 kan forøvrig ha en, i sin fra låsestemplets 1 svingeaksel 3 vendende del som ligger nær ved døren og i retning mot svingeakselen, ombøyd flik for støtte av trykkfjærens 8 ene ende. wall, which is opposite to the one at which the locking piston 1 is located, is stored one end of a compression screw spring 8, in which is fitted one end part of the joint 9 which protrudes from the opposite end of the spring and which is close to its outer end provided with studs 10 stored in grooves 11 and slidable along these. These grooves 11 are arranged so that the distance of the pins 10 from the pivot axis 3 of the locking piston is increased when the locking piston 1 turns to the locked position. The torque of the spring will thus not change with its tension. Furthermore, the transition from the free position to the locked position or vice versa is soft, as at this point the pin is furthest down in the groove 11 and thus close to the shaft 3. The link 9's connecting pins 10 on the locking piston 1 are arranged in relation to its pivot shaft 3 in such a way that they the door's closing and opening movement passes a line of force from the spring 8 towards the swing axis, whereby the spring pressure, in addition to contributing during the door's closing movement to swing the locking piston to the locking position, also swings the locking piston 1 to its final release position when the pins 10 during the door's opening movement pass the said line of force. The locking piston 1 is stopped in the fully open position partly by means of the internal abutment of the locking piston against the inside of the capsule 2 and partly by means of the joint 9 abutment against the same inside of the upper wall of the capsule 2. Incidentally, the door-opening capsule 2 may have a bent flap for supporting one end of the pressure spring 8 in its part facing away from the pivot shaft 3 of the locking piston 1, which is close to the door and in the direction of the pivot shaft.

Claims

1. Bib lock for doors, flaps etc. with a bolt rotatably stored in a capsule, which is provided with an arm which protrudes from the capsule and cooperates with a fitting attached to the door frame, the capsule having a bearing surface for its attachment to the door and the bolt being under the influence of a bearing surface essentially parallel compression spring clamped between the capsule and the crossbar, characterized in that the compression spring (8) is helical and clamped between the capsule (2) and one or more pins (10) which are slidably stored in at least one crossbar being a guide slot (11), which starts close to the pivot axis (3) of the crossbar and first runs substantially perpendicular to a radius through the pivot axis and then extends outwards along a convex curve in relation to the pivot axis, so that the pin or pins (10) below the crossbar (1) turning to the locking position is gradually shifted outwards towards the open end of the slot (11), as the inside of the capsule (2) prevents the extension from the guide slot and the line of force of the pressure springs during this movement of the pins the pivot axis of the rail passes in the guide slot.

2. Bib lock according to claim 1, characterized in that the bolt (1) has two side walls perpendicular to the capsule's (2) contact surface against the door which are provided with the guide slots (11), and that the bolt is stored on one of these side walls fixed and through the capsule walking axis (3).

3. Bib lock according to claims 1 and 2, characterized in that the capsule (2) which opens towards the door on its part facing away from the pivot axis (3) of the bolt (1) has, close to the door, a flange bent inwards in the direction of the pivot axis to support the spring's (8 ) one end.

4. Bib lock according to one of the claims 1-3, where the fitting has a larger and a smaller flange protruding into the arm's path of movement, characterized in that the outer part of it in the open position with the edge surface of the door substantially parallel to the arm (4) is bent outwards, so that when the door closes, this arm (4) hits the larger flange (7), whereby the arm 4 engages in the opening (6) between the flanges and the bolt (1) is turned to the locking position, in which the arm is pressed by the spring (8 ) against the smaller flange (12).
