Definitions
- the present invention relates generally to a striking plate and more specifically to a striking plate that includes an adjustable tongue for adjustment of the engagement of a latch bolt or lock bolt with the striking plate.
- the striking plate includes a generally flat face plate that includes one or more openings in which a lock bolt or latch bolt can engage when the door is closed.
- security-type-striking plates also include a generally U-shaped or V-shaped so-called box that prevents access to said bolts from "behind" the striking plate.
- Known striking plates may also include an adjustable so-called tongue, which adjusts engagement between, e.g., a latch bolt and the striking plate. This engagement is set so that the door will not be spaced from the door frame when the bolt engages the striking plate.
- Fig. 1 is a cross-sectional view of the plate at a level with a latch-bolt- receiving opening.
- the illustrated arrangement includes a striking plate element 10', a box 20' and a tongue 30' integral with said box.
- the tongue can be bent away with the aid of an appropriate tool, for instance, so as to obtain the correct tongue measurement, referenced "d" in the figure.
- the tongue 30' does not extend up to the level ofthe upper side ofthe plate element, i.e. the side facing to the right in the figure. This results in a problem whereby a latch bolt is in danger of becoming jammed or stuck in an intermediate position, indicated in broken lines in the figure.
- a further example of known lock technology is described in Swedish Patent Publication SE 346 582.
- the striking plate described in this publication comprises a lip that includes two forwardly projecting and adjustable tongues whose outer end edges lie in the plane of the striking plate and are bent along a short distance.
- the primary object of the invention according to SE 346 582 is to simplify fitting of the striking plate, and does not solve the aforesaid problem associated with the danger of a latch bolt fastening in an intermediate position in the opening defined between the ends ofthe tongues and the striking plate.
- An object of the present invention is to provide a striking plate of the aforesaid kind with which the problem mentioned above associated with a striking plate that includes an adjustable tongue measurement is avoided.
- the invention is based on the realisation that an adjustable tongue can extend up to the level ofthe upper surface ofthe striking plate post.
- the adjustable tongue and the plate element overlap mutually in the direction of movement ofthe latch bolt.
- Fig. 1 is a cross-sectional view of a known striking plate
- Fig. 2 is a cross-sectional view corresponding to that of Fig. 1 but showing a striking plate constructed in accordance with the invention
- Figs. 3-5 are perspective views ofthe inventive striking plate shown in Fig. 2;
- Figs. 6 and 7 are respectively a side view and a plan view of the inventive striking plate shown in Figs. 2-5;
- Figs. 8a and 8b are respectively a plan view and a cross-sectional view of the inventive striking plate, showing an adjustable tongue in a first position;
- Figs. 9a and 9b are respective views corresponding to those of Figs. 8 and 8b, showing the adjustable tongue in a second position.
- the plate 1 includes a plate element 10, a box 20 and a box-integral tongue 30.
- the plate element includes an opening 11 adapted to receive a latch bolt 40 of a lock (not shown) fitted to a door 42.
- the plate element has a generally flat upper surface 12, 16 which faces outwards when the striking plate is fitted to a door frame, i.e. faces towards the door and the latch bolt 40 included in a door lock.
- the tongue 30 includes a sliding part 32, which has a surface that lies essentially on a level with the upper side 12 of the plate element. As the latch bolt 40 engages the striking surface, designated 13 in Fig. 2, of the plate element when closing the door, the latch bolt is caused to slide over said upper surface 12 and then to glide over the tongue portion 32 prior to reaching the position shown in the figure when the door is fully closed.
- the slide portion of the tongue 30 includes three teeth 32a-c (see Fig. 3), the shape of which is adapted to corresponding notches in the aperture 11.
- the mutual spacing b between the teeth is smaller than the width of the latch bolt 40. This results in an overlap between the slide portion 32 and the plate element 10 in a direction r of the movement of said latch bolt 40, therewith preventing the bolt from sinking down into or fastening in a gap between tongue and plate element.
- the latch bolt has a smooth sliding surface all the way from the striking surface 13 to the opening 1 1.
- the plate element 10 has two mirror-imaged latch bolt openings 11. Located centrally between these openings is a lock bolt opening 14.
- the plate element 10 also includes two symmetrically disposed screw holes 15. Because the entire striking plate is symmetrical, the same striking plate can be used for fitting both left-hand and right-hand locks.
- the box 20 has a generally U-shaped cross-section (see Fig. 2) and includes a generally flat first side 20a, a generally flat second side 20b and a third side which includes two flat parts 20c, 20d, where the part 20c is generally parallel with the first side 20a and the second part 20d is angled to said first part.
- the second part 20d has two holes 21 for screws 22. These screws will extend obliquely into the doorframe, as clearly shown in the figures. The significance of this will become apparent from the following description, particularly from the description made with reference to Figs. 2, 8 and 9.
- the screw 22 can be screwed-in by virtue of a recess 11a provided in the edge of the opening 11, said recess enabling the mounting holes to be placed close to the bolt post.
- the central positioning of the lock bolt opening 14 results in uniform loading of the two oblique mounting screws 22, which is advantageous from a strength aspect. The closer the screws to the plate element, the better the fastening ofthe screws 22.
- Figs. 8a and 8b illustrate a position in which the tongue measurement "d" is a minimum.
- the teeth 32a-c are essentially adjacent the plate element 10 in the absence of any clearance.
- Figs. 9a and 9b show the tongue at maximum tongue measurement. In this case, the teeth 32a-c are in a border position in which they do not overlap the plate element in the direction of movement of the latch bolt, shown by the arrow "r" in the figures.
- a practical setting range is as large as 3 millimetres, or still greater in certain cases.
- the tongue 30 is adjusted preferably with the aid of an appropriate tool, such as a screwdriver or the like, with which the tongue can be inclined at a desired angle relative to the first side 20a ofthe box.
- the tongues 32b are bent or curved slightly upwards, i.e. to the right in the figures.
- the upper side of respective tongues will thereby lie essentially level with the upper side of the plate element, regardless of the tongue setting.
- attitude ofthe tongue 30 in the illustrated embodiment has been said to be set by means of a screwdriver or some other appropriate tool, it will be obvious that the attitude ofthe tongue can be adjusted and set with the aid of a setting screw that extends into the tongue.
- the tongue 30 has been shown to include three teeth 30a-c, it is, of course, conceivable to use any number of teeth, provided that the mutual spacing of the teeth is smaller than the width of a co-acting latch bolt.
- box 20 has been shown to have a U-shaped cross-section, the box may be given shapes that deviate from the illustrated shape, such as a generally V-shape, etc.
- the plate element has been shown as being generally flat, although it will be understood that the plate element may include a part which is angled to said upper side 12, as in the case of rebated doors, for instance.
