Definitions

  • the invention relates to a device for protecting against burglary, of the type, with which a bolt catching case mounted on or in a frame and cooperating with a rock in or on a hinged panel, is connected with an active element by means of a core line protected by an outer sheath, said core line extending through a guide opening in said lock catching case towards a fixed anchoring location, in such a way, that in case of a displacement of the bolt catching case as a result of an attempt at burglary the active element will be moved to close an alarm circuit.
  • Such a device is disclosed in NL-8301465. With this device the core line and the sheath together form a bowden cable. In case of an attempt at burglary the core line will follow the displacement of the bolt catching case, while the sheath will remain stationary. Thus there will be a displacement of the core line within the stationary sheath, due to which the active element will be actuated.
  • the advantage of this type of device is to be seen in that the active element and consequently the alarm will already enter into operation in the initial stage of the attempt at burglary, i.e. when the damage is still limited in extent.
  • the invention aims at further improving this device.
  • this aim is achieved in that the core line is arranged to hold the active element against spring action in an inoperative position, an auxiliary element being mounted on the frame adjacent the guide opening for the core line, said auxiliary element cooperating - in case of a forced displacement of the bolt catching case, with the portion of the bolt catching case delimiting said guide opening so as to perform a scissor action onto said core line.
  • a door frame post is indicated at 1 and has a bolt catching case 2 mounted on it.
  • the bolt catching case 2 cooperates with a lock 3 indicated by dash-dotted lines in the drawing and mounted on the inner side of a door 4 which is also and partially indicated by dash-dotted lines.
  • the bolt catching case 2 is connected to a tight flexible line 6, which extends through a sheath 6a fastened onto the frame wood and passes through a guide opening 7 in the upper wall 2a of the case 2 towards a fixed anchoring location 8 within the bolt catching case 2.
  • the device according to the invention further comprises a plate-like element 9 bearing on the upper wall 2a of the case 2 and having a bent flange portion 9a screwed on the frame post 1.
  • the element 9 has a slot-like passage way for the line 6 extending parallel to the plane of the closed door.
  • the longitudinal slot edge 11 turned away from the frame post 1 extends towards the edge portion indicated at 7a at a distance corresponding to the thickness of the line 6.
  • the longitudinal edge 11 is sharpened and constitutes the stationary part of a scissor, the other part of which is constituted by the marginal portion 7a delimiting the guide opening 7.
  • the flexible line 6 is connected, at its end turned away from the case 2, to the "active" element 13, which is making part of an alarm device not further shown in the drawing.
  • said element is constituted by a contact lever 13 cooperating with a fixed contact 14.
  • the contact lever 13 and the fixed contact 14 are making part of an electric alarm circuit.
  • the line 6 is kept tight by a spring 15 which pulls the lever 13. Under normal conditions, i.e. with tight line 6, the latter keeps the contact lever 13 against the action of the spring 15 in its opened position relative to the fixed contact 14.
  • the bolt catching case 2 1 has been embedded into the frame post 1.
  • the guide opening for guiding the flexible line 6 is constituted by an edge portion of the bolt catching plate embedded in the respective plate of the frame post 1, said edge portion being bent to form an eyelet 16.
  • the eyelet 16 cooperates in a hinge-like manner with an upper and a lower eyelet 17, which are similarly formed at an edge of an element 9 1 which is fastened by screws on the frame.
  • the upper and lower edges of the eyelet 16, as well as the opposite edges of the eyelets 16, are sharpened.
  • the eyelets 16 and 17 are positioned in vertical alignment one to another and the flexible line is guided through the passage formed by said eyelets towards the fixed anchoring location 8 which in this case may be simply formed by a knot at the lower end of the flexible line 6.
