Definitions

  • the invention relates to a striking plate assembly in accordance with the preamble of claim 1.
  • Striking plates for door locks to be mounted on door frames of profiled structure differ from striking plates to be mounted on wooden door frames in both construction and securing. Durability and rigidity against attempted burglaries of various kinds are, however, always expected of the striking plate. Therefore safety striking plates for door frames made of profiled metal need to be manufactured of special steel, which raises the manufacturing costs thereof.
  • An aim of the present invention is to provide a novel striking plate assembly for door frames of profiled metal or alike, by which a more advantageous distribution of the forces generated in a case of attempted burglary is achieved in the door frame.
  • an aim of the invention is to provide a striking plate assembly where conventional materials, less expensive than special steels, can be used, but where the requirements for the durability and rigidity of the construction are not, however, compromised.
  • the invention provides a striking plate assembly in accordance with claim 1.
  • Optional features of the invention are defined in the other claims.
  • the striking plate assembly comprises a striking plate provided with an opening for a bolt, in which striking plate a bolt casing is arranged, the bolt casing being adapted for location in the cut-out of a door frame.
  • the bolt casing comprises a section arranged to extend beyond the region of the cut-out in the longitudinal direction of the frame, when the striking plate assembly is already mounted in the frame. Additionally, a bolt casing end opposite to the section extending beyond the cut-out in the frame, is shaped so as to allow the inserting of the bolt casing through the cut-out in the frame.
  • the bolt casing comprises a section that, after being mounted in the frame, is arranged to extend only in one direction beyond the region of the cut-out in the longitudinal direction of the striking plate, and in such a manner that a space is left between this section and the striking plate.
  • the bolt casing extends also beyond the region of the opening in such a way that a space for the frame is left between the bolt casing and the striking plate.
  • Said section extending beyond the cut-out may be arranged to be supported at least partly by the frame between said section and the striking plate at least in a case of attempted burglary.
  • the assembly may comprise a support member on the opposite side from the aforementioned section in respect of the opening, which support member is arranged to be mounted inside the door frame and secured to the striking plate so that the wall of the frame is located between the support member and the striking plate.
  • the support member is preferably a support plate.
  • the rigidity of the construction can be further improved by locating the support plate partly inside the bolt casing, whereby the support plate supports the bolt casing in the cross-direction of the striking plate.
  • the support plate may be provided with a protrusion at its end facing the opening and being supported by the striking plate.
  • the support plate is preferably provided with a slot in the longitudinal direction of the striking plate, through which a securing member, e.g. a combination of a screw and a threaded sleeve, is adapted to be inserted in order to secure the bolt casing to the striking plate. Due to the slot the same striking plate can be used in conjunction with door lock bodies with various locking bar dimensions.
  • a securing member e.g. a combination of a screw and a threaded sleeve
  • the surface of the bolt casing end opposite to the end extending beyond the cut-out in the frame is shaped so as to allow the extracting as well as the inserting of the bolt casing through the cut-out in the frame when being or detached from as well as mounted in the door frame.
  • the perpendicular projection of the bolt casing onto the surface of the striking plate may extend in the longitudinal direction of the striking plate over a distance greater than the length of the cut-out in the frame in the direction of the frame.
  • the bolt casing can, after being mounted in the frame, be arranged to extend beyond the cut-out.
  • the reference number 1 refers to a striking plate, which is provided with an opening 1a for receiving a bolt 8 for a door lock 7.
  • a bolt casing 2 which is, when applying the present assembly, inserted via a cut-out 3c in a door frame 3, inside the profiled structure of the frame.
  • the assembly comprises a support member, which is a support plate 4 in the embodiment shown in the Figures.
  • the support plate 4 is secured to the striking plate 1 and to a profiled frame section 3b by means of a screw 5 and a combination 6 of a screw and a threaded sleeve.
  • the assembly is mounted in a door frame 3, 3a, 3b made of profiled metal or the like so that the profiled frame section 3b of the door frame (shown in the Figure above the cut-out 3c), remains partly between the striking plate 1 and the support plate 4.
  • the bolt casing 2 is U-shaped and it extends both below and above the opening 1a.
  • the bolt casing 2 is also adapted to extend beyond the region of the cut-out 3c in the longitudinal direction of the frame, after the assembly has been mounted in the profiled frame.
  • the bolt casing 2 extending below the bolt opening is shaped so that some space is left for the frame section 3a between the bolt casing 2 and the striking plate 1 and thus the bolt casing extends beyond (below, as shown in the Figures) the region of the cut-out 3c so that the frame section 3a can extend between the bolt casing and the striking plate.
  • a section 2a of the bolt casing 2 is thus supported by the profiled door frame section 3a, in the Figures below the cut-out 3c in the profiled frame, whereby the forces exerted on the lower part of the striking plate are partly transmitted to the door frame. This is the case especially at burglary attempts, which are described below with reference to Figures 5 and 6.
  • the support plate 4 above the opening 1a and the cut-out 3c in the profiled frame is located partly inside the bolt casing 2 thus supporting it in the cross-direction of the striking plate 1.
  • the support plate 4 is provided with a protrusion 4a, which is in the upper part of the bolt opening 1a and is supported directly by the striking plate 1.
  • the support plate 4 is provided with a slot 4b in the longitudinal direction of the striking plate 1, through which the combination 6 of a screw and a threaded sleeve is arranged to be inserted in order to secure the bolt casing 2 to the striking plate 1.
  • the threaded sleeve 6a is shaped so as to transmit force over to the support plate 4 as well as to the bolt casing 2 to further enforce the structure.
  • the slot 4b makes it possible to use the same striking plate in conjunction with door lock bodies with various spindle distances.
  • Figure 2 shows an assembly designed for a shorter spindle distance whereas Figures 5 and 6 show a case where the bar distance is longer.
  • the screw 5 can be fixed in the lower screw hole in the support plate, as shown in Figures 2, 5 and 6.
  • the spindle distance refers to the distance between the front plate, i.e. the plate in conjunction with the lock housing with one or more openings for the bolt, and the spindle or spindle opening of the lock.
  • the spindle distance can be increased e.g. by arranging a special additional spacer under, or in conjunction with, the front plate.
  • FIG. 5 depicts the striking plate assembly according to the invention applied in conjunction with a hook bolt lock 7, to which the invention is particularly applicable.
  • a sliding door is an appropriate application.
  • the bolt 8 of the lock 7 extends through the bolt opening 1a inside of the striking plate assembly and the bolt casing 2.
  • the support plate 4 is now secured by a screw 5 to the lower screw hole in the support plate, whereby the support plate 4 is located farther away from the bolt opening 1a than in the case shown in Figure 2.
  • a lock 7 provided with a longer spindle distance can also be used.
  • FIG 6 is somewhat exaggerated in order to clarify the situation.
  • the force transmitted by the hook bolt 8 to the striking plate 1 makes it bend and move with respect to the profiled frame 3.
  • the loading of the screw fastening 5, in the Figure located above the cut-out 3c can be reduced so that some of the force is transmitted to the profiled door frame 3b, in the Figure above the cut-out 3c, which frame is pressed between the support plate 4 and the striking plate 1.
  • the section 2a of the bolt casing extending in the Figure below the cut-out 3c in the profiled frame is supported by the profiled door frame section 3a, whereby the forces exerted on the lower part of the striking plate are partly transmitted directly to the door frame.
  • the loading of the screwed joint 5a, in the Figure below the cut-out 3c is reduced.
