Description

The invention relates to a door lock provided with a hook bolt in accordance with the preamble of claim 1.
The Finnish patent 104199 discloses a door lock of the kind meant above, in which a separate hook part of a hook bolt is turnably journalled to a guide part movable in the lock case. An aim of the invention is to further develop lock arrangements for a door or other turnable wings provided with a hook bolt so that the possibilities for installation of this kind of locks would be more extensive and their burglary preventing properties would further be improved. A further aim of the invention is that the lock would be secure as to the operation and advantageous as to its costs.
The aims of the invention can be met as is more closely disclosed in claim 1 and in the other claims. According to the invention the hook bolt comprises a pivot arrangement by means of which the hook part is movable with regard to the guiding part in the longitudinal direction of the front plate. In addition the lock case includes a guiding groove for guiding the pivoting point of the hook part both in the longitudinal direction of the front plate and in the direction of movement of the guiding part. This makes it possible to move the hook part inside the striking plate so that the hook part can turn into its locking position in a smaller space than before. Hereby it is possible to essentially reduce the requirement for space in the direction of the movement of the guiding part and the protruding length of the bolt, whereby possibilities for installation of the lock in different locations can correspondingly be increased.
In practice the pivot arrangement of the hook part is accomplished by means of a pivot pin, which is movably supported to a guiding groove arranged in the guiding part and extending mainly in the longitudinal direction of the front plate.
The shape of the guiding groove in the lock case is with advantage selected so that in the first phase of the movement of the hook bolt out into the protruding position the pivoting point of the hook part is moved at the same time downwards with regard to the front plate. When the hook part is moved out from the opening for the bolt in the front plate, the guiding groove extends substantially only in the direction of the movement of the guiding part.
In order to secure the turning movement of the hook part into the locking position the lock case includes a guiding surface which, after the hook part is moved through the opening for the bolt in the striking plate, is arranged to guide the hook part so that it is turned with regard to its pivoting point inside the striking plate into its locking position.
In order to improve burglar-proof properties of the lock and especially to prepare for a situation where one tries to lift the entire door provided with the lock away from its hinges by making use of the hook bolt, at the front plate side end of the guiding groove in the lock case at the position corresponding to the locking position of the hook part there is an extension part in the guiding groove extending upwards in the longitudinal direction of the front plate and separated from the guiding groove by means of a connection piece. This connection piece is with advantage fixed to the lock case through shallow parts, which can be broken with said pivot pin. Correspondingly the upper surface of the hook part includes a recess which is arranged in cooperation with the upper edge of the opening for the bolt in the front plate to prevent moving of the hook bolt inside the lock case after said connection piece is broken by means of said pivot pin. As a consequence of these measures the hook bolt remains fully jammed as a result of an attempted burglary and thus the attempted burglary utilizing said technique is effectively stopped.
In order to secure the preventing measures mentioned above the hook part is additionally so dimensioned that in its fully protruding locking position it fills the major part of the opening of the striking plate in the longitudinal direction of the front plate. For its part this prevents already as such moving of the door out from its hinges.
The construction of the bolt can be kept simple and secure as to its operation when the guiding part of the hook bolt is continuously located inside the lock case.
In the following the invention is described as a way of example with reference to the attached drawing, in which
  • Fig. 1 shows a side view of a known door lock arrangement installed in a door and the lock case opened,
  • Figs. 2-9 show an embodiment of a door lock according to the invention in different operating positions of the hook bolt.
The known door lock shown in figure 1 comprises a lock case 1, which is provided with a front plate 3, by means of which it is fixed to a door 2 or the like. The lock includes a hook bolt 4, which comprises a guiding part 5, which is linearly movable inside the lock case and to which a hook part 6 of the hook bolt is turnably journalled by means of a pivot pin 7. The lock case comprises also a guiding groove 8, which guides the pin 7 and thus the movements of the hook bolt. The hook bolt 4 is moved directly by means of a key 9 of the lock. In addition the lock includes a set of spring-loaded locking discs 10 movable with the key 9 of the lock and including a locking channel 11 for a lock pin 12 fixed to the guiding part 5 of the hook bolt. The operation of the lock as such is quite conventional and is described for instance in said Finnish patent 104199, so it is not here described in more detail. Figure 1 shows also a striking plate 14 for the lock fixed to a door frame 13 or the like and including a housing 15 for the bolt. In figure 1 the hook bolt 4 is in its protruding locking position, in which the hook part 6 has entered through an opening 3a for the bolt in the front plate and through an opening 14a for the bolt in the striking plate into the housing 15 so that the hook part 6 extends some length parallel with an inner surface 14b in the striking plate.
The arrangement according to the invention illustrated in figures 2-9 differs from the known arrangement of figure 1 in the first place so that in accordance with the invention when the hook bolt is moved from the withdrawn position into its protruding locking position the hook part 6 of the hook bolt is arranged to move in successive order in opposite turning directions relative to the guiding part 5 at the same time as the pivoting point of the hook part is moved in the direction of the front plate. Hereby the space required for the turning of the hook part of the hook bolt can be reduced and the protruding length of the bolt can be essentially shortened without compromising the security of locking and operation of the arrangement.
In practice this is accomplished so that also in this case the hook part 6 of the hook bolt is turnably journalled to the guiding part 5 by means of the pivot pin 7, but the pivot pin 7 can move in a guiding groove 5a arranged in the guiding part and extending in the longitudinal direction of the front plate 3. In addition the guiding groove 8 in the lock case includes two branches 8a and 8b extending in different directions. The first branch 8a is transverse with both the direction of movement of the guiding part 5 of the hook bolt and the front plate 3. As a consequence of this when the hook bolt is moved outwards from the lock case the hook part 6 is at the same time turned somewhat in clockwise direction relative to the guiding part 5 (figure 3). The second branch 8b extends in the direction of the movement of the guiding part 5, so when the hook bolt is moved further the hook part 6 moves at the same time through both the opening 3a for the bolt in the front plate and the opening 14a for the bolt in the striking plate (the latter is not shown; figure 4). Now the hook part 6 can turn by means of the pivot pin 7 in counterclockwise direction with regard to the guiding part 5 into its locking position, which occurs partly due to gravity and partly due to guiding surfaces 6b in the hook part and 17 in the lock case respectively (figures 5 and 6).
In accordance with the invention the guiding groove 8 in the lock case includes further an extension part 8c, which extends upwards in the direction of the front plate 3 and which is normally separated from the branch 8b by means of a connection piece 16, which is fixed to the lock case through shallow parts 16a. The shallow parts 16a are so dimensioned that if a lifting force acts on the lower edge of the hook part 6 for instance in the pursuit to lift the door out from its hinges, the pivot pin 7 of the hook part 6 breaks the shallow parts 16a at the same time as the pin 7 is moved on one hand along the guiding groove 5a in the guiding part and on the other hand along the extension part 8c of the guiding groove in the lock case upwards in the figures. This is illustrated in figures 7 and 8.
Moving of the door out from its hinges as such will fail since the hook part 6 is dimensioned with regard to the opening 14a for the bolt in the striking plate so that the construction does not allow an upward movement long enough. As a consequence of this movement, however, the entire hook bolt is jammed due to a recess 6a made in the hook part 6 and being in cooperation with the upper edge of the opening 3a for the bolt in the front plate. A bevel surface in the recess 6a together with the pivot pin 7, the broken connection piece 16 and the guiding grooves 5a and 8c act in a wedge-like manner on the hook part 6 preventing hereby effectively any further measures for this part (figure 9). Hereby damaging of other inner members of the lock by means of the bolt can also be prevented, whereby the requirements for strength for their part can correspondingly be kept lower and thus the manufacturing costs for the lock case itself can be kept lower as well.
It is to be noted that the hook bolt arrangement according to the invention can be applied in different lock cases independent on whether the movements of the bolt are carried out directly through a key, a key operated locking mechanism or for instance through an electric or electromagnetic arrangement. In addition to doors the lock can naturally be installed also to corresponding lockable locations such as hatches, turnable wings etc. Thus, the invention is not limited to the embodiment shown but several modifications are feasible within the scope of the attached claims.
