Definitions

  • the present invention relates to a striker plate which comprises a plate intended to abut against or be recessed in a surface on a door frame facing the edge of a door leaf, the plate having at least one aperture for accom ⁇ modating a dead bolt projecting from a lock mounted in a door leaf, and a box which is recessed in the frame and is of one-piece manufacture with the plate.
  • Striker plates of many different types are previously known in this art, in which the striker plate has a plate which is intended to abut against or be recessed in that surface on a door frame which faces the edge surface of a closed door. From the inside of this plate, there then ex ⁇ tends a box recessed in the door frame and either of one- piece manufacture with the plate (see for example Swiss Patent Specification No. 485 936), or which may be pro ⁇ quizzed as a separate part which is, for instance by weld- ing, subsequently secured in the plate.
  • the present invention has for its object to re- alize a striker plate which may be manufactured in a simple and rational manner, while at the same time achiev ⁇ ing superior mechanical strength and thereby providing a major obstacle to attempted break-in.
  • the present invention has for its object to realize a striker plate which is designed in such a manner that it offers maximum difficulty in separating the plate of the striker plate from its box.
  • the invention further has for its ob ⁇ ject to realize a striker plate which may be anchored in the door frame also to that side of the door frame which faces an adjacent wall.
  • the present invention has for its object to realize a striker plate which may read ⁇ ily be modified so that it can be adapted to different in ⁇ stallation dimensions of the lock in the thickness di ⁇ rection of the door.
  • the striker plate disclosed by way of introduction is characterized in that the plate consists, at least along that edge portion which faces away from the abutment surface of the frame, of portions with double folded sheet material, the leading wall of the box being recurved from the interior of these sheet portions.
  • the box also has a rear wall with a recurved foot which abuts against and, for example by welding, is se ⁇ cured to the inside of the plate.
  • a mounting plate which extends approximately parallel to the plate and is intended to be anchored to the inside of the frame.
  • the striker plate may readily be adapted, with retained basic design and construction, to different installation posi ⁇ tions of the lock in the thickness direction of the door.
  • Fig. 1 is a side elevation of a first embodiment of the striker plate
  • Fig. 2 is an end elevation of the striker plate of Fig. 1 mounted in a door frame shown in cross-section; is a section taken along the line A-A in Fig. 1; is a view corresponding to that of Fig. 1 of a modified embodiment of the striker plate; is a top plan view of an adjuster plate employed in the striker plate according to Fig. 4; is a view corresponding to Fig. 2 of the striker plate according to Fig. 4; and is a top plan view of a mounting plate employed in connection with the striker plate according to Figs. 4 and 6.
  • Fig. 2 shows a horizontal section through a door frame 2 with an abutment surface 4 against which a door will come into abutment when the door is closed.
  • the same Figure also shows an end elevation of a striker plate designed according to the present invention, the plate having an outside 10 by which is meant that side which is turned to face the edge surface of a door when the door is closed.
  • the inside 11 of the striker plate is turned to face away from the edge surface of the door and faces towards a wall (not shown) surrounding the door frame 2.
  • reference numeral 9 refers to the forward edge of the striker plate, while reference numeral 8 designates its rear edge.
  • the striker plate is provided, in a per se known manner, with a plate 1 which constitutes the outside 10 of the striker plate. Further, the striker plate is provided, in a conventional manner, with a box 3 on the inside of the plate 1 , the box being recessed in a corresponding aperture in the door frame 2. This aperture may possibly be a through passage so that it extends through the door frame to its inside 17.
  • This wall will hereby be trans ⁇ versely directed, possibly at right angles to the plate 1 and has, at its edge most proximal the plate, a recurve which forms a foot 7 which abuts against the rear side of the plate 1 (its outer material layer) .
  • the foot 7 will be, in the vertical direction of the striker plate, of elongate configuration and connect to the rear edge portion 8 of the striker plate so that this will also have double material thickness.
  • the striker plate has, in this re ⁇ gion, gently arched contours which defy a firm grip for a burglary tool such as a chisel.
  • the above-described design of the striker plate is not only favourable from the point of view of mechanical strength, but also entails that the material thickness of the single material layer may possibly be less than is the case in a conventional striker plate without any conse ⁇ quential reduction of mechanical strength as compared with the conventional striker plate.
  • the box 3 is of quite considerable length, for which reason this will have, seen from the end, the form of an approximately U-shaped recess seen in cross-section, being open at the end walls of the box.
  • the plate consists of double material, first along the forward edge portion 9, secondly along the foot portion 7 of the box at the rear edge portion 8 of the plate, and thirdly along the short ends of the box with the double material portions 5 there displayed, which offer a high degree of rigidification of the plate if this were to be longer than shown in the Figure.
  • the plate is pro ⁇ vided, in direct connection with the short ends of the box 3, with narrow transverse portions 16 of single material. However, these extend in a direction towards the forward edge 9 of the plate no further than flush with the forward wall 14 of the box 3.
  • At least the bottom 15 of the box 3 is provided with threaded holes or bushings 12 for accommodating threaded pins 19 (see Fig. 6) which are in ⁇ tended to extend through the inner wall 13 of the door frame 2 in order to abut against an adjacent surface of a wall or wall stud surrounding the frame.
  • recesses 33 in the plate are illustrated at the transition between the forward edge of the box 3 and the plate 1. These recesses serve to permit access of adjust- ment tongues against which the dead bolts of the lock abut in the closed position of the door, and which, by bending in a "rearward-forward" direction, are intended to be brought into such positions that the door has no clearance when closed.
  • These locking tongues are realized by ap- proximately U-shaped slots in the forward wall 14 of the box 3, the bottom of the U being approximately parallel to the plate 1 and located closely inside the plate.
  • Figs. 4 and 6 show a striker plate which is modified in relation to the above-described striker plate.
  • the striker plate according to Figs. 4 and 6 is provided with a separate adjustment plate 20 which is shown in plan view in Fig. 5.
  • the adjustment plate 20 is provided with an in ⁇ ner edge 21 with projecting studs 22 which extend through corresponding apertures in the bottom 15 of the box.
  • the studs 22 and the apertures in the bot ⁇ tom 15 of the box constitute guide means which localise the adjustment plate 20.
  • this is provided, on its inner edge, with spigots 23 by means of which it is fixedly welded in the bottom 15.
  • the outer edge 24 of the adjustment plate 20 is provided with upper and lower end portions 25 which are accommodated in corresponding reces ⁇ ses in the plate 1 so that, thereby, the outer edge of the adjustment plate 24 will be positionally fixed in the breadth direction (in the forward-rearward direction) of the striker plate.
  • the adjustment plate 20 will be approximately parallel to the forward wall 14 of the box 3.
  • the adjustment plate 20 also serves the purpose of adjusting the striker plate in such a manner that the clearance will be insig ⁇ nificant between a dead bolt engaging in the striker plate and the striker plate proper, this preventing the closed door from rattling in the lock.
  • the adjustment plate is provided, starting from its for- ward edge 24, with transversely directed slots 26 which form flexible adjustment tongues 27.
  • These adjustment ton ⁇ gues 27 are to be bent in a direction towards or away from the forward wall 14 of the box in order to realise the above-mentioned adjustment.
  • the striker plate according to Figs. 4 and 6 will be of superior mechanical strength in relation to the striker plate according to Figs. 1-3, in which the ad- justment tongues are directly punched out in the forward wall 14 of the box 3.
  • the broken lines 2 intimate the outer contour of that door frame in which the striker plate according to the present invention is mounted.
  • the striker plate is provided, on its inner side and in cooperation with the bottom wall 15 of the box 3, with a mounting plate 28 which abuts against the inside 17 of the frame 2 or which is recessed there- in.
  • the mounting plate 28 is ideally located in that space which is formed between the inside of the frame 2 and a wall surface in association with the frame.
  • the mounting plate 28 is provided with apertures 29 by the intermediary of which it may be screwed in place in the frame 2.
  • the mounting plate 28 may be secured in the striker plate in a plurality of al ⁇ ternative ways, but, in order to permit mounting, the mounting plate must be capable of being retrofitted once the striker plate has been placed in its aperture provided in the door frame 2 or, alternatively, pivoted in relation to the striker plate so that it may be slid through the aperture of the box in the frame and placed on the inside thereof when the striker plate is mounted.
  • the bottom wall 15 in the box of the striker plate be provided with slot-shaped apertures 30 extending in the vertical direction, through which ap ⁇ proximately Z-shaped bent anchorage tongues 31 may be hooked onto the mounting plate 28.
  • the an ⁇ chorage tongues 31 will, in the assembled state, be loc ⁇ ated interiorly in the box and abut against the outside of the bottom 15 of the box, while the outside of the major portion of the mounting plate 28 proper will abut partly against the inside of the bottom of the box and partly ag ⁇ ainst the frame 2.
  • the apertures designated 32 in Fig. 4 are located in line with the bushings 12 and serve as a passage for a turning tool for manoeuvring the threaded pins 17.
