Abstract
Description
- Fig.1
- The safety lock with lever-type handle and emergency handle, shown locked and with the emergency handle idle, an internal perspective view.
- Fig.2
- The same as Fig.1, unlocked.
- Fig.3
- The unlocked position in Fig.2 with the door released by the lever handle.
- Fig.4
- The lock in the locked position with the door released by means of the emergency handle.
Claims (7)
- Safety lock (10) for doors (60) with an emergency handle (15) in the form of a horizontal translating bar, a bolt plate (12) supported by a base plate (11), a normal lock (14) and a normal lever-type handle (13)
characterized in that, due to the effect produced by its translation against the door (60) the emergency handle (15) determines movement of the bolt plate (12) against the base plate (11) with a consequent break in the mechanical connection between said bolt plate (12) and the bolt (39) of the normal lock (14) permitting, due to movement of said handle (15), longitudinal translation of said bolt plate (12), consequent release of the door (60) even when its normal lock (14) is locked, and opening of said door (60). - Safety lock for doors with an emergency handle as in claim 1,
characterized in that mechanical connection between the bolt plate (12) and the bolt (39) in the normal lock is made by means of an intermediate device comprising a pin (44) fixed to the base plate (11) on which pin a cylinder (40) governed by a spring (46) can freely rotate, said cylinder having an orthogonal extension (41) subject to action by a tie rod (48,49) fixed to the bolt (39) of the normal lock (14), there being fixed on the bolt plate (12) a locking tooth (70) whose movement, affected by translation of the bolt plate (12), is aligned with the plane of said extension (41) and interferes with the axis of the pin (44) of the cylinder (40), there being made in said extension (41) a radial slit (58) whose width is greater than the size of said locking tooth (70) so that when the normal lock (14) is locked, the door (60) is blocked by the bolt plate (12) itself being blocked by interference on the part of its locking tooth (70) against the extension (41), while when the normal lock (14) is unlocked, its lock (39) having determined by means of said rod (47, 48) rotation of the extension (41) until its slit (58) is aligned with the tooth (70), it becomes possible by means of the normal lever-type handle (13) for the bolt plate (12) to translate freely, the door (60) to be released and then to open. - Safety lock for doors with an emergency handle as in claim 2
characterized in that, following rotation of end arms (72) with which the emergency handle (15) is articulated onto the base plate (11), the emergency handle (15) determines rotation of a vertical shaft (16) substantially parallel to the bolt plate (12), provided with an arm (86) at whose end thereis a hook (88) that penetrates inside a longitudinal slot (62) in the bolt plate (12) and an intermediate vertical rod (87), pressure by said rod (87) on the bolt plate (12) determining, due to rotation of the shaft (16), movement of said bolt plate (12) against the base plate (11) overcoming resistance set up by springs (18) and so removing the locking tooth (70) away from the extension (41), action by the end hook (88) to the arm (86) on the end (63) of the slot (62) determining translation of the bolt plate (12) and therefore release of the means blocking the door (60) against its frame, it being thus possible to open the door by simply pressing on the emergency handle (15). - Safety lock for doors with an emergency handle as in claim 3
characterized in that the vertical shaft (16) supports an arm (90) whose position corresponds to that of a glass pane (27), replaceable, supported by the base plate (11) so that rotation of said shaft (16), caused by movement of the emergency handle (15), determines breakage of said glass pane (27). - Safety lock for doors with an emergency handle as in claim 4,
characterized in that the glass pane (27) is associated to an electric sensor (91) that signals breakage of the glass to a control centre. - Safety lock for doors with an emergency handle as in claim 1,
characterized in that there is a pin (50) on the bolt plate (12), said pin acting on a sensor (54) that signals translation of the bolt plate to a control centre. - Safety lock for doors with an emergency handle as in claim 1,
characterized in that all moving parts are made of stainless steel.
