Definitions

  • the invention relates to a door lock arrangement according to the preamble of claim 1 comprising a lock body fitted with a front plate and a cover plate; the lock body has at least one bolt protruding from an opening in the front plate and can be attached by screws or the like fitted in screw holes of the front plate and can be furnished with said cover plate installed on the front plate, in which case the door or the like also has a recess for the front plate.
  • a door lock is usually installed at the door factory, and it would be simplest for the door factory to use a standard recess made at the position of the front plate. If the lock is then fitted with a cover plate, the cover plate will unpleasantly protrude from the end surface of the lock unless the recess for the lock's front plate is simultaneously deepened. However, such deepening made after initial installation is quite a demanding task so it will be quite difficult to achieve a tidy installation without damaging the surface coating of the door. On the other hand, the door factory is practically unable to fit all of its doors with a front plate recess that would depthwise correspond to the use of a cover plate because if there was no cover plate, the door lock would be installed too deep, which would also result in a quite unpleasant appearance.
  • US 611,979 discloses a door lock arrangement according the preamble of claim 1, that can be mounted with or without a cover plate.
  • the objective of the invention is to create a door lock arrangement with as simple structure as possible that allows easy installation of a door lock in a door or the like pivoting blade either with or without a cover plate and that minimises the required installation actions in different situations and ensures a tidy result.
  • the back side of the front plate that is arranged against the door or the like has protrusions at the positions of the screw holes, and in case the lock body is installed without a cover plate, the front plate is supported by said protrusions in the front plate recess.
  • the lock body can further be fitted with said cover plate that has screw holes corresponding to the screw holes in the front plate for attaching the cover plate using the same screws or the like, in which case the lock body is arranged to be installed so that the front plate is attached to the door or the like supported by its back surface that is at least substantially independent of said protrusions.
  • the combined thickness of the front plate and cover plate shall be chosen so that when installed together, the combined thickness substantially corresponds to the depth of said front plate recess.
  • the invention allows easy and simple installation of the front plate of a door lock and an optional cover plate installed on it so that their thickness in different cases will always roughly correspond to the front plate recess made in the door.
  • the door factory does not need to consider whether the locks used in the doors are fitted with a cover plate or not but the doors can be manufactured using a standard recess for the front plate, which will bring cost savings.
  • the door lock When it is desired to equip the door lock with a cover plate, the door lock is detached and cavities are made for said protrusions on the back side of the front plate only. This can be simply achieved by removing a small amount of material from their positions. This allows the door lock to be installed slightly deeper, supported by the back surface of the front plate, which makes it possible to neatly install the cover plate on it. Said removal of material from the positions of said protrusions only can be easily achieved without damaging other parts of the door surface particularly as the functionality of the solution does not require too much precision with regard to the dimensions of this local cavity.
  • the depthwise dimension required for the standard recess for the front plate can be easily taken into account by manufacturing the front plate from a slightly thinner sheet material than usual, so that the combined thickness of the front plate and the cover plate suitably corresponds to the depth of the front plate recess in the door.
  • the screw holes in the front plate and cover plate are preferably furnished with mutually corresponding oblique guide surfaces that are most preferably arranged to correspond to the oblique surfaces in the head of the fixing screws. This allows simple and firm installation of the cover plate.
  • reference number 1 refers to a door or the like pivoting wing with a recess 1a in which a door lock 2 is installed, said door lock comprising a lock body 3 equipped with a front plate 4 and a bolt 5.
  • the door has a separate recess 1b for the front plate 4.
  • the lock body 3 is attached to the door through the front plate 4 with screws 6.
  • the front plate has protrusions 4a in connection with the holes for screws 6, which means that the front plate 4 is attached in the recess 1b supported by the very protrusions 4a.
  • the height of the protrusions 4a is in the order of 0.5 mm.
  • the recess 1b here is a so-called standard recess with a depth of approximately 2.5 mm.
  • the front plate 4 is manufactured of a material that is slightly thinner than conventional, approximately 1.5 mm thick. Even though it therefore does not completely fill the recess 1b, the protrusions 4a make the difference quite small and unnoticeable.
  • Figure 3 illustrates a situation in which a cover plate 7 has been installed on the front plate 4 within the same front plate recess 1b.
  • this has been done by first detaching the door lock 2 and making cavities 1c for the protrusions 4a at the positions of the screws 6 in the recess 1b.
  • the location of the cavities in connection with the holes for the screws 6 is such that making them does not impose the risk of damaging visible surfaces of the door.
  • the exact size and shape of the cavity do not play any essential role but the main issue is that the cavities 1c must be able to receive the protrusions 4a and thus allow the front plate 4 to be pressed slightly deeper into the front plate recess 1b.
  • the cover plate 7 When the cover plate 7 is attached on the front plate 4 using the same screws 6, the combined thickness of the plates 4 and 7 approximately corresponds to the depth of the recess 1b and provides a tidy result.
  • the thickness of the cover plate 7 can typically be chosen as 1 mm.
  • the front plate 4 is supported by its back surface 4c outside the protrusions 4a against the bottom of the recess 1b.
  • guide surfaces 4b in the screw holes of the front plate 4 and the corresponding guide surfaces 7a in the cover plate are shaped as mutually corresponding oblique surfaces that correspond to the shape of the screw head 6a.
