Definitions

  • the present invention relates to a hinge, and in particular to a hinge designed to offer increased security when fitted, e.g. to a door or window.
  • Hinges commonly comprise a pair of plates provided with hollow cylindrical extensions on their abutting longitudinal edges.
  • the hollow cylindrical extensions in combination form the eye of the hinge.
  • a pivot pin is inserted through the eye.
  • one of the plates is fixed, for example, to a door frame and the other of the plates to an inner edge of the door.
  • hinges of this sort with a free pin.
  • the two parts of the hinge can be fixed separately to the structural members which are to be hinged together and the pin dropped in place once those two members have been assembled.
  • this facilitates the process of construction since the hinges can be pre-fitted off-site. It also makes it a simple matter to remove the door from the doorframe, for example when redecorating.
  • the pivot pin represents a significant weakness from the point of view of security. If a door is mounted using, e.g., a butt hinge having a free pin, then someone wishing to force entry can do so simply by removing the pin and lifting the door out of the frame. Even where the hinge is constructed so that the pin is captive to the hinge, it is still in general possible to force the pin out to allow separation of the two parts of the hinge.
  • hinges which has a stud on one of the fixing plates which, when the hinge is closed, engages an aperture in the opposing plate.
  • Examples of such hinges are disclosed in GB-A-1402487. Although this provides some resistance to movement as long as the plates are in close contact, as soon as the plates are separated by more than the depth of the plate it again becomes possible to separate the two parts by moving one away from the other in the plane generally parallel to the plates.
  • this construction has not found commercial acceptance.
  • GB-A-2164089 discloses a hinge construction in which a projecting surface formed in one plate abuts a recessed surface in the other plate. Again this suffers the disadvantage of requiring a specially machined slot to accept the recessed surface.
  • a hinge comprising a pair of hinge plates and formations extending from opposing inner surfaces of the hinge plates, the formations inter-engaging to hold the hinge plates against separation ip. the closed position of the hinge by relative movement in the plane generally parallel to the plates, is characterised in that the formations comprise at least one pair of upstanding members, the upstanding member on each hinge plate extending towards the other hinge plate in the closed position and overlapping the other upstanding member.
  • the present invention provides a hinge offering greatly increased security without adding significantly to the cost of manufacture.
  • the hinge remains simple to fit.
  • the construction of the hinge is such that the two hinge plates need to be separated by a distance as great as the combined heights of the two upstanding members before it becomes possible to separate the plates by moving one past the other.
  • a further important advantage of the present invention is that it allows the use of a free-pin construction without compromising security.
  • the upstanding members are tags formed integrally with the respective plates.
  • each tag is formed by cutting a region of the plate and pressing it so that it extends generally at right angles to the plate.
  • the aperture in at least one plate for receiving the tag on the other plate is provided by the region cut away to form the tag on the at least one plate.
  • the apertures are both so formed, with the aperture on a first plate being formed on the side of the tag on the first plate away from the eye of the hinge and the aperture on the second plate being formed on the side of the tag on the second plate nearer the eye of the hinge, when the hinge is closed the tag on the first plate lying nearer the eye of the hinge than the tag on the second plate, in use the said first plate being fixed to a fixed structural member, such as a doorframe, and the second plate being fixed to a movable member, such as a door.
  • the upstanding inter-engaging tags can be used independently of the hinge to provide a security fitting or "dog bolt" suitable for a variety of applications.
  • a security fitting suitable for a door or window comprising a pair of plates arranged to be fixed to respective surfaces, and formations extending from opposing inner surfaces of the plates, the formations inter-engaging to hold the plates against separation by relative movement in the plane generally parallel to the plates in the closed position of the door or window and is characterised in that the formations comprise a pair of upstanding members, the upstanding member on each plate extending towards the other plate in the closed position of the door or window and overlapping the other upstanding member.
  • the present invention also encompasses methods of manufacture for the hinge and fitting of the first and second aspects.
  • Figure 1 is an exploded view
  • Figure 2 is an end view
  • Figure 3 shows the hinge fitted to a door
  • Figure 4 is a view of the hinge plates of a second embodiment
  • Figure 5 is an end view of the hinge of Figure 4.
  • Figures 6a and 6b are a dog bolt embodying the invention fitted to a door and a perspective view of one of the two plates making up the dog bolt respectively;
  • Figures 7a to 7d are a plan view, end view, side view, and sectional view in a closed position of a third embodiment of,a security hinge.
  • a butt hinge comprises a first hinge plate 1 and a second hinge plate 2 each having extensions 3, 4 on their respective inner longitudinal edges.
  • the extensions 3, 4 are bent over to form bearing surfaces of a generally hollow cylindrical shape.
  • the two hinge plates 1, 2 are brought together with their inner longitudinal edges abutting and the respective extensions interleaved to form the eye of the hinge.
  • a pivot pin 5 is then inserted through the eye of the hinge.
  • the hinge is formed of mild steel 2mm thick. The process of manufacture takes as its raw material steel coil strip of a width corresponding to the desired width for the hinge.
  • the strip is fed from a loading cradle into a blanking press which in a single operation presses from the blank the two hinge plates complete with the extensions 3,4, a number of countersunk screw holes and the apertures and tags 6,7,8,9. After each blanking operation the strip is indexed by a distance corresponding to the desired length for the hinge.
  • the extensions are rolled to form the eye of the hinge.
  • the two plates are then assembled and, in the case of a captive pin hinge, the pin inserted and the head of the pin spun.
  • the tags are then bent upwards to lie at right angles to the plates.
  • the first plate is screwed to the inside edge of the door and the second plate is screwed to an opposing surface of the doorframe, as seen in Figure 3.
  • the presently described hinge includes on each plate an upstanding tag 6, 7 and an aperture 9, 10 for receiving the corresponding tag on the other plate.
  • a recess having a depth less than that of the plate might be used.
  • the tags are located so that they overlap in the longitudinal direction and are positioned close to each other, but not necessarily touching, with the smaller tag on the second plate nearer the inner edge of the hinge.
  • This smaller tag on the second plate is received within a specially cut aperture 10 in the first plate.
  • the tag 6 on the first plate is received within the aperture 9 on the second plate formed in the process of cutting that plate's tag.
  • each of the hinge plates has a tag and an aperture 8' , 9' formed by the process of cutting and pressing the tag.
  • the present invention may also be used with other hinge constructions, such as the "invisible" hinges described in GB-A-1402487.
  • FIGS 7a to 7c show a third example of a hinge embodying the present invention.
  • the hinge pin is omitted from these views.
  • a pair of upstanding tags 6a, 6b, 7a, 7b are provided on each hinge plate. The use of two pairs of inter-engaging tags further increases the strength of the hinge and its ability to resist attempts to force the hinge apart.
  • FIGS 6a and 6b One example of a dog bolt embodying the second aspect of the present invention is shown in Figures 6a and 6b below.
  • the two identical plates making up the dog bolt are attached respectively to inner surfaces of a door frame and a door. They are configured so that with the door closed the tag on each of the bolt members extends into the aperture on the opposing bolt member. The inter- engagement of the upstanding tags on the bolt members holds the door against being lifted out of the frame, even after an external hinge has been removed.

Abstract

Dans une charnière simple, chacune des surfaces internes opposées des deux lames (1, 2) est dotée d'un élément droit (6, 7). Ces éléments droits sont placés de manière à se chevaucher lorsque la charnière est fermée, chacun saillant dans une encoche ou ouverture pratiquée dans la lame opposée. Lors de l'utilisation, si on enlève la fiche (5) et sépare partiellement les lames, un élément vient s'engager dans l'autre afin d'empêcher la séparation de celles-ci par un déplacement relatif dans le plan généralement parallèle à celui des lames.
