Definitions

  • This invention relates to a door system suitable for use in protecting doorways and entrances in temporarily unoccupied premises.
  • CH-A-47 370 discloses a window system comprising a window surround structure formed and arranged to define a window opening and a window panel hingedly mounted in said window opening so as to be pivotally movable between a closed position and an open position said window panel and window surround structure being provided with an interengaging retaining means formed and arranged for retaining the window panel against pivotal movement from its closed position in a first position of the window said window being hingedly mounted so as to be vertically movable through at least a limited distance and having a height relative to the door opening such as to permit vertical movement through a limited distance in its closed position, and in said retaining means being formed and arranged for retaining door panel against pivotal movement from its closed position in a first position of the window, and for permitting pivotal movement of the window in a second position of the window vertically displaced from said first position.
  • the retaining means is provided on the outside.
  • the window panel is readily breakable.
  • the system provides little resistance to an attack from the outside for gaining unauthorized entry to the interior side of the window.
  • the window cannot be opened from the outside without damage. It is an object of the present invention to avoid or minimize one or more of the above disadvantages.
  • the present invention provides a security door system suitable for use in providing a high level of security against which door system comprises a door surround structure formed and arranged to define a door opening and a door panel hingedly mounted in said door opening so as to be pivotally movable between a closed position and an open position said door panel and door surround structure being provided with an interengaging security lock means for substantially securing said door at least against vertical movement and interengaging retaining means formed and arranged for retaining the door panel against pivotal movement from its closed position in a first position of the door characterized in that said door is hingedly mounted so as to be vertically movable through at least a limited distance and has a height relative to the door opening such as to permit vertical movement through a limited distance in its closed position, and in that said retaining means is disposed substantially, at the restricted access side of the door and is formed and arranged for retaining the door panel against pivotal movement from its closed first position of the door, and for permitting pivotal movement of the door in a second position of the door vertically displaced from said
  • the door is hingedly mounted so that in its closed pivotal position and its first vertical position its lower edge in the plane of the door surround structure is supported immediately above, for example not more than about 6 mm, preferably not more than about 3 mm, the inner bottom edge of the door opening.
  • the door surround is provided at the upper edge of said door opening on its outer face with a shield means extending downwardly therefrom by a distance greater than the separation between the upper edge of the door in the plane of the door surround structure and the inner top edge of the door opening in the closed pivotal position and first, vertical, position of the door so as to cover the gap therebetween.
  • the door opening and door panel are dimensioned so that their respective edges are disposed in overlapping relating in a closed position of the door with said door on the rear face of the door surround structure, said door surround structure being provided on its rear face with securing means for securing of said door surround structure, in use of the system, to at least the jambs of said opening in said building, with the outer edges of said door surround structure disposed in overlapping relation with said lintel, jambs and threshold on the outside faces thereof in use of the door system.
  • the door panel In use of the door system of the invention, the door panel is held securely in its closed position against pivotal opening movement by the retaining means and must first be lifted vertically to disengage the retaining means. This however will only be possible when the security lock means are unlocked. Since the security lock means are required to function only to prevent lifting of the door panel then can be of relatively lightweight and simple construction as the main resistance to an opening force will be borne by the retaining means. Since the respective parts of these can be fixedly secured and need not be movable in any respect they can readily be made to be of a strong construction which can contribute to the strength of the door structure itself, in a relatively simple and economic manner.
  • the door system of the present invention is of relatively economic construction and can be easily secured in an opening in a building by securing the door surround structure to the existing jambs with a high degree of security and resistance to attack due inter alia to the overlapping between the door and door surround and between the door surround and jambs, lintel and threshold, while at the same time screening the securing means used to fix the door surround in place.
  • the precise extent of overlap between the door surround and jambs, lintel and threshpld is not critical so that by varying the extent of overlap it is possible to use a single size of door system with a range of different opening sizes.
  • Fig. 1 shows a door system 1 comprising door surround structure 2 defining a door opening 3 at which is hingedly mounted 4 a door panel 5.
  • the door surround structure 2 is of a generally rectangular C-shaped section with the main upright 6 of the C-shape forming the front outside face 7 of the door surround structure 2.
  • the door surround structure 2 is provided with a plurality of securing means 8 for securing of the structure 2 to the jambs 9, threshold 10 and lintel 11 at an opening 12 in a building 13 normally closed by an existing door 14.
  • the securing means 8 comprise a clamping plate 20: a clamping bolt 21 for clamping the clamping plates 20 towards anchor plates 15 secured to the door surround 2 at the inside and outside faces of the jambs 9 etc.; and a spacer bolt 22 fixed to the clamping plate 20 with a spacer nut 23 spaced from the anchor plate at distance such that a substantially even clamping force is exerted across the anchor plate and clamping plate and the respective opposed faces of the jambs etc.
  • the door panel 15 is of generally Z-shaped section at its outer edges 24 with an outwardly extending circumferential flange 25 set back from the principal plane of the door panel 5 at the rear of a shoulder 26.
  • the flange 25 In the closed position of the door panel 5 the flange 25 abuts the radially inward hooked end 17 part of the door frame structure section 2 to overlap the latter on its rear face whilst the principal plane of the door panel is substantially flush with the front outside face 7 of the door surround structure 2, the door panel 5 in effect nesting radially inwardly inside the door surround structure 2 so as to be substantially supported against horizontal lateral displacement in the plane of the door system.
  • the door panel is hung in the door surround structure on hinge means 4 comprising respective hinge parts 27, 28 secured to respective ones of the door surround structure and the door panel, so as to permit at least a limited degree of vertical movement of the door on said hinges.
  • the structural strength and rigidity of the door panel 5 and surround 2 are reinforced at their rear with the aid of horizontal reinforcing or bracing members 30 which have at the free side 31 of the door panel 5, retaining plates 32 which project laterally behind the door surround 2. At their lower edges the retaining plates 32 have notches 33 which engage retaining pins 34 behind their heads 35 to prevent pivotal movement of the door on its hinges in an opening direction, said retaining pin and plate constituting a strong and secure retaining means for the door.
  • the door panel 5 has a height in the plane of the door slightly less (e.g. about 20 mm less) than that of the opening 3 in the surround 2 so that it can be vertically displaced on its hinges in its pulled-to closed pivotal position. More specifically the structure is formed and arranged so that in a first position of the door wherein the retaining means interengage there is only a narrow clearance 36 of some 3 mm or so between the bottom edge 37 of the door 5 and the inner bottom edge 38 of the door opening 3. Between the upper edge 39 of the door 5 and the inner top edge 40 of the door opening 3 there is a larger gap 41 of up to 20 mm. This gap 41 is however concealed from view and protected against insertion of tools by a shield means in the form of a cover plate 42.
  • a shield means in the form of a cover plate 42.
  • a security lock means 43 which may be of any conventional form e.g. key operated, combination-type or card- operated, is provided on the door panel 5 for engagement with a suitable keeper means 44 on the door surround 2 in its locks condition.
  • a suitable keeper means 44 on the door surround 2 in its locks condition.
  • a suitable form of tool which can as shown be very simple is shown in Fig. 5 and comprises a thin blade 45 extending at right angles from a lever arm 46 towards one end 47 remote from a hand grip portion 48 thereof.
  • the blade is inserted into the clearance and then pressure applied on the lever to tend to rotate the lever parallel to the plane of the door thereby raising one side 49 of the blade up as the other side 50 bears down on the surround 2 at the bottom of the opening 3.
  • the door system in its locked condition provides strong and secure protection to an opening with the fixings used to install the system well protected against outside interference. Whilst at the same time permitting installation and removal of the system in a quick and simple manner.
  • the door hinge mounting can be arranged .to permit sufficient vertical displacement to lift the door panel entirely off the hinge in the open position of the door to permit easier handling of the door panel and surround separately from each other.
  • Fig. 6 is a detail view of the bottom corner 51 on the hinged side of the door opening 3.
  • the corner 51 is provided with a generally lazy-'Z' shaped section elongate door support member 52 having a lower web 53 connected along its outer edge 54 to the door opening bottom edge 38, and an upper web portion 55 extending rearwardly behind the door surround structure 2 above the door opening bottom edge 38.
  • the height of the upper web portion 55 above the door opening bottom edge 38 is selected to be such that when the door is lifted to its second; raised, vertical position from its fully closed position and then swung open, it will swing out over and onto the door support member 52 and be supported at or above the level of its second position.
  • the door when open, may be closed by simply swinging it to without the need for first lifting it into a raised position in order to allow the respective parts of the retaining means 32-35 to clear each other prior to engagement when the door drops down on its hinges as it clears the support member upper web portion 55.
  • Fig. 7 shows a modified form of retaining means 56 comprising a substantial plate-form nose 57 projecting outwardly of the free side edge 58 of the door panel 5 to which it is secured, and a keeper 59 secured to the opposed edge 60 of the door surround structure 2.
  • the keeper 59 comprises a horizontal rearwardly extending plate 61 and a vertical plate 62 extending rearwardly alongside it.
  • the vertical plate 62 is notched 63 at its upper corner 64 immediately adjacent the door surround structure 2 to provide a recess in which the nose 57 is received and captively held against horizontal movement corresponding to pivoting open of the door (without first raising it).
