Definitions

  • the present invention relates to a security device for limiting the opening of a door.
  • it relates to a security device for securing a door partly open.
  • a security device which allows a door to be securely partially opened, in order to safely view and identify a caller outside of the door.
  • the door is limited to opening only a small amount, and cannot be opened fully, so that a caller cannot enter through the doorway.
  • One such conventional device is a chain, extending between a door frame and an area adjacent to the door handle. This has the disadvantage that the chain is relatively weak, and so may be broken if a caller exerts a force on the door.
  • the fastenings connecting the chain to the door and the door frame are also relatively weak. Thus, an unwanted caller may be able to break through a partially open door secured with a chain.
  • the present invention provides a security device for securing a door pivotally mounted in a door frame, the security device comprising: a first bar moveable relative to the door; and a first bracket which supports a first end stop spaced apart from the plane of the door frame; wherein the first bar is moveable between: a first position in which the first bar engages the first end stop when the door is pivoted open and limits the , opening of the door; and a second position in which the first bar does not engage the first end stop when the door is pivoted open and thereby allows the door to be fully opened.
  • the door can be securely held in a partially open position. This allows verification of the identity of a caller, without allowing entry of the caller through the doorway.

  • a doorframe 52 surrounds the door 50, and supports the hinges 51.
  • the security device 1 may be fitted onto a conventional external or internal door.
  • the door 50 may already have a conventional lock 60 for locking the door in its closed position.
  • the lock 60 is typically located on a side of the door opposite to the hinges 51.
  • the bars 2, 3 are offset from the hinges 51 in the plane of the door 50.
  • the upper bar 2 and lower bar 3 are also offset from each other in the plane of the door.

When the bar 2 contacts the bracket 8 at the end of the slot 9 further movement of the bar 2 is not possible, and so the bar 2 will prevent the door 50 from being opened further.
  • the security device 1 thus prevents the door 50 from opening by more than approximately 100mm at the side opposite the hinge 51, when the security device 1 is engaged.
  • the lock 4 is provided with a handle 10 on the inside of the door.
  • the handle 10 is connected to the lock 4 such that turning of the handle 10 will cause the upper bar 2 to move downwardly and the lower bar 3 to move upwardly.
  • the handle 10 thus may actuate retraction of the bar 2 out of the slot 9 of the bracket 8, allowing the door to be fully opened.
  • the security device 1 of the present invention is shown fitted to a conventional door 50 in a cutaway side elevation view.

Abstract

La présente invention concerne un dispositif de sécurité (1) permettant de fixer une porte (50) installée en pivotement dans un encadrement de porte qui comprend : une première barre (2; 3) mobile par rapport à la porte ; et un premier support (8; 12) qui supporte une première butée espacée du plan de l’encadrement de porte. La première barre (2; 3) est mobile entre une première position dans laquelle la première barre engage la première butée lorsque la porte est pivotée pour s'ouvrir et limite l’ouverture de la porte ; et une seconde position dans laquelle la première barre n’engage pas la première butée lorsque la porte (50) est pivotée pour s'ouvrir et permet ainsi l’ouverture totale de la porte.
