  • the lock is configured such that when the upper and lower slides are undisplaced, i.e. the engaging members are retracted, the plunger protrudes from the interior casing while the shoulder 68 is beneath shoulder recess 69 restraining the upper slide and therefore restraining the directly coupled further mechanism from being displaced from the undisplaced configuration. Depression of the plunger, through engagement with the catch plate as the wing is closed causes displacement of the shoulder 68 from the shoulder 69 enabling the slides to be displaced.
  • the engaging members are configured so that they move simultaneously in opposite directions and in the direction of the hooks. In a preferred embodiment they move towards each other and the hooked portions move towards each other to be engageable behind shoulders of the catch plate.

  • the cylinder recess connects to a barrel aperture 97 in the wall of the lid through which the head of the interior barrel 8 protrudes to be accessible.
  • Each slide in some forms is biased by a compressed compression spring 1S0, as shown in Fig 4, held compressed by being retained between the end 152 of the slide and a shoulder 151 of the case 3.
  • the spring 100 is supported about a follower 153 having at one end a return 154 that is within an aperture 155 in the side of the slide while the other end extends through a slotted aperture 157 of the shoulder 101.
  • Adjacent to return 104 follower 103 has a shoulder 158 and the spring is supported between this shoulder 108 and the shoulder 101
  • the mechanism is configured such that when the slide is half way between its undisplaced and fully displaced configurations, the follower 103 is substantially orthogonal to the locus of movement of the slide, this mechanism acting to urge the slide towards its extreme outwardly disposed or inwardly disposed limits of displacement; in so doing, acting as an over-centre device.
  • Each slide is preferably so biased.
  • the catch plate 9 has a forward wall 101 disposed towards the front edge of the interior assembly with openings 102, as shown in Fig 3, to provide passage for the engaging members to recesses 103 into which the hooked portion of the engaging arm extends.
  • the catch plate preferably comprises a vertically elongated catch casing 104 which supports a forward wall comprising a separate channel 105, restrained relative to the casing by two spaced springs 173 located between the catch casing and channel.
  • Screws 107 are adjustable in and out to selectively set the distance between the channel and catch casing as is required and to accommodate small deviations in the wing 2 and element 10.
  • the catch casing can be attached to the element defining the wing opening in two different ways: screws 109, including the head can be passed through apertures 110 in the channel to be inserted in vertically elongated first fixing apertures 111 in the catch casing to be fastened to the element 10 - the catch plate being vertically adjustable because of the elongation of the fixing recesses.
  • screws 112 may be passed from the outer face of the catch casing through vertically elongated second fixing apertures 113 in the catch casing to be fastened into element 10 — the catch plate again being vertically adjusted because of the elongation of the fixing recesses.
  • plugs 114 are inserted within the second fixing apertures.
  • Each second fixing aperture is intersected by transverse apertures 115 commencing at the front edge of the catch casing and support a grub screw 116 which threadedly engage the walls of the recesses. After the insertion of each plug the grub screw is tightened to bite into the plug to retain the plug in the second fixing recesses to render the screw 112 inaccessible.
  • each end of the channel is an end shoulder 117 overhanging the recesses 103 to provide in-part a forward wall of the recess 103 and by so doing providing a counter-levered engageable shoulder behind which the hooked portions 23 of the engaging member can locate so that the hooked portion cannot be withdrawn horizontally from behind the shoulder 117 - this action corresponding to attempted forced entry.
  • the channel comprises an elongated steel channel or a single zinc diecast member.
  • the casing comprises a single casting to provide increased strength.
  • the casting comprises a substantially elongated first plate-like portion 118 integrally attached at right angles to another substantially second elongated plate-like portion 119 (corresponding in this embodiment to the base of the casing), each providing for the other a web-like portion to resist bending of the catch casing.
  • a single, exterior cylinder and operating member each being operable to displace the lock to and from the operative configuration, the cylinder also being key operable to lock and unlock from the first locked configuration.
  • An operating member and no cylinders the member being operable to displace the lock to and from the operative configuration.
  • a single, interior cylinder the cylinder being key operable to displace the lock to and from the operative configuration and to lock and unlock the lock from the first locked configuration.

Abstract

L'invention porte sur une serrure pour une aile mobile définie par un côté intérieur et un côté extérieur, la serrure incluant un moyen pouvant être enclenché, un boîtier pouvant être monté par rapport au côté intérieur, des moyens d'enclenchement incluant au moins un bras d'enclenchement supporté par rapport au boîtier, chaque bras d'enclenchement précité pouvant être déplacé dans une configuration fonctionnelle pour pouvoir être enclenché avec le moyen pouvant être enclenché dans le but de limiter un déplacement de l'aile dans une direction d'ouverture, des moyens d'actionnement pour amener chaque élément d'enclenchement à se déplacer vers la configuration fonctionnelle et à partir de celle-ci, incluant un élément d'actionnement pouvant être actionné à la main en prise fonctionnelle, par des moyens de pêne, avec chaque élément d'enclenchement, lesdits moyens de pêne comprenant au moins un pêne pouvant être déplacé et étant caractérisé par une configuration fonctionnelle correspondant à chaque élément d'enclenchement se trouvant dans la configuration fonctionnelle, les moyens d'actionnement incluant en outre un cylindre comportant un barillet pouvant être actionné par clé, en prise fonctionnelle avec les moyens de pêne par un premier élément pouvant être angulairement déplacé, les moyens de pêne et chaque élément d'enclenchement pouvant être déplacés vers leur configuration fonctionnelle respective, et à partir de celle-ci, par actionnement de l'élément d'actionnement et par actionnement du cylindre, le barillet étant caractérisé par un axe pivotant qui coupe l'axe de pivotement du premier élément.
