Patlico Rights II. V., established in Willemstad, Curasao Door lock construction.

The invention relates to a door lock construction with a latch bolt and underneath a dead bolt, with a front plate, which has pass-through openings for the two shooters and, behind that front plate, a lock box, which is adapted for accommodating movement and operating mechanisms. for the shooters, and the insertion holes which are substantially directly below each other for the actual actuators for the shooters to be deployed from the outside, such as latch (es), crank (s), key, etc.

So-called day and night locks of the above-mentioned type are provided with a latch for the latch bolt, while the latch bolt can be closed and opened by means of a key.

In the case of so-called locks, which are used in doors that do not need to be closed, the latch bolt is generally sufficient. When the same lock case is used for this purpose, it is therefore not necessary to provide the provisions for moving and operating the dead bolt here. The front plate can then only contain an opening for the latch bolt.

In the case of so-called closet locks, the reverse is the case, i.e. only the so-called "night" bolt is required. Usually the actual actuator is then a key.

Finally, there are so-called WC or bathroom locks, which differ from the aforementioned day and night locks, in that the dead bolt is not operated by means of a key, but generally by means of a latch or handle or the like.

As will become clear from the foregoing, in principle, for the first three types of lock construction mentioned above, a single cabinet design will suffice. The parts that may not be needed - the shooter with the associated movement and operating mechanism - need not be fitted, or at least the associated 7810278 i4 ~ 2. It is not necessary to use a running key or crank. However, for the fourth lock construction, namely the WC and bathroom lock version, the same box construction cannot be used: the insertion hole for the actuator for the "night" shooter must herein be an insertion hole for a latch, handle or the like and not for a key, as for the other species.

In practice, four further versions will be added to the four mentioned versions, instead of left-hinged, right-hinged doors. However, an ordinarily known latch bolt known per se can reduce the number from eight to four.

The object of the invention is now for all four resp. eight applications mentioned may suffice with one and the same lock case design, so that a considerable simplification is achieved in the manufacture and in particular when keeping in stock, while it is furthermore possible to adapt to each of the three with the same lock case construction, and seven, respectively - when using a reversible latch bolt - other uses than those for which the lock was initially used.

For this purpose, a lock construction of the above-mentioned type according to the invention is further characterized in that the lock case is subdivided into, on the one hand, a top box part containing the two shooters, which of the insertion holes only contains and is designed for the actual actuator for the latch bolt for incorporating - subject to the actual controls - the complete movement and actuation mechanisms for the latch bolt and at least a substantial part of those mechanisms for the latch bolt, and on the other hand detachable from said upper lock case part, but fixedly connected thereto, bottom lock case part.

This lower lock case part could be omitted when used as a padlock with only one latch for the latch bolt. If instead of Applicable as day lock and deadbolt, use as WC or bathroom lock, a second version for the lower cabinet part instead of the lower cabinet part for the day and night lock version could be attached to the upper cabinet part .

35 However, in further elaboration of the inventive idea, it is 7810278 B.C.

3 advantageous when the lower lock case part is designed to be attachable to the upper lock case part in two operating positions rotated about a vertical axis 180 ° and has two mutually different insertion holes for actual actuators for the 5 dead bolt, each of which for one of the two uses - positions are intended and the positions of use concerned are approximately the same height and the same distance behind the front plate, one of which is a keyhole. With this embodiment it is thus possible with one lower case part to suffice to nevertheless be able to realize adaptation to all four above-mentioned uses. The object of simplified production, and in particular also storage, which is the object of the invention is thus achieved to an even greater extent. In particular, it is thus possible to always use the same lock construction according to the invention for all the stated uses in this more refined embodiment. This makes mass production possible on a much larger scale. The drawback that for some of the applications more provisions are made to the lock construction than is strictly necessary for that application case, in particular for use as a padlock and as a lock, is more than compensated for by the considerable advantages of a much greater mass production.

The transition from application as day and night lock to application as WC or bathroom lock can be realized in a simple manner by simply changing the position of use, as mentioned above, by turning about a vertical axis through 180 ° after releasing the lower case part of the top and, after that turning, fixing the bottom case part to the top case part again in the fixed position.

According to a simple embodiment in a lock case part which can be converted into two positions of use in the above-described manner, mutually interlocking profiles can be formed on the two lock case parts and securing means can further be provided, which fasten the lock case parts brought into engagement with those profiles. keep each other attached.

According to a special embodiment according to the invention 7810278 τ **, these profilings, in the direction transverse to the front plate, can be collapsible grooves and ribs at the bottom and top edges of the side walls of the top and bottom lock case parts, respectively. , while at the rear edges of the side walls 5 of the top lock case part on the one hand and on the side edges of a sliding plate mutually interlocking rib and groove profiles are formed such that the sliding plate can be slid downwards along the rear edge of that case part when the lower box part is retracted to keep that bottom lock case part in place.

It is clear that the manner in which the lower and upper cabinet part can be detachably attached to each other, wherein the lower cabinet part can moreover be set up in the two above-mentioned different positions of use, also within the scope of the invention in various ways. other ways can be realized. In particular, as in the above-mentioned embodiment with the ribs and grooves, the subdivision surface need not be an exclusively substantially horizontal surface. For example, the top cabinet part can also extend sideways next to the bottom cabinet part. Likewise, within the scope of the invention, the means for securing the state of use or the states of use of the lower case part can also consist of means other than the above-mentioned sliding plate.

What is important according to the invention is that with one universal lock construction the needs can be met in all the aforementioned four use cases and in the case of the version with the lower case part which can be converted into two uses in the same embodiment thereof. both a day and night lock and a toilet or bathroom lock can be realized.

The invention will now be further elucidated with reference to the drawing.

In Fig. 1, I-IV respectively indicate a day and night lock, a loop lock, a closet lock and a toilet or bathroom lot. The entire lock construction is indicated by the reference number 1, the front plate with 2, the latch bolt with 3, the dead bolt with k, the actual lock case with 5j, the insert hole for the actual operating device - a handle or handle - for the latch bolt with 6, the keyhole t for inserting the key, as the actual actuator for the dead bolt with T and the insert hole for the handle or handle, as the actual actuator for the dead bolt - at the WC or bathroom lock - with 8.

The above-mentioned reference numerals are indexed, for various embodiments, with the relevant Roman numeral I-IV. In fig. 1, the dashed line DE shows the dividing line, according to which for the invented lock construction, as shown in more detail in fig. 2, and dèSr indicated by the reference numeral 1 - without index - the lock case 30 is divided into an upper lock case part 5A and a bottom lock case part 5B. Also in Fig. 2 the division line DE, here indicated as a dash-dot line, is indicated.

The reference numbers 1-8 here are without index,

According to the invention, the lock case is, according to the invention, subdivided into on the one hand one of the two 7810278 6 not further shown in fig.

T

a dual shooter-containing upper case section, which contains only the insertion hole 6 for the actual actuator - crank or latch - for the latch bolt and which is adapted to receive - with the exception of that actual actuator - the complete movement and 5 actuating mechanisms for the latch bolt and at least a substantial part of said mechanisms for the dead bolt, and on the other hand one of said upper lock case part 5A detachable, but fixed to it, lower lock case part 5B. In the illustrated embodiment, this lower lock case part 5B comprises on the one hand an insertion hole 7 for a key as the actual actuator for the dead bolt and, on the other hand, an insert hole ö for inserting the actual actuator - handle or knob and the like - also for the dead bolt. From the part of Fig. 2, in which the lock case 1 is shown in side view, it appears that the two insertion holes 7 and ö are at substantially equal height. The keyhole with its vertical center line lies approximately the same distance behind the front plate 2 as the insertion hole 6. The part of fig. 2 in which the front plate 2 is shown in front view, shows the height and shape of the opening 13 for passing through it. of the latch bolt and of the opening lA for the latch bolt. The screw holes in the front plate 2 are indicated by 9 and 20.

Fig. 2 shows the completed lock case from the top box part 5A and 5B in which a day and night lock is formed. that is to say, with the insertion key as the effective insertion opening 7, substantially directly below the insertion hole 6 for the actual actuator - handle, handle, etc. - for the latch bolt. "

In Fig. 3, only the part 5B in position about 180 ° mounted on a vertical axis is indicated with 5B ', thus the key opening 7 and the insertion opening ö have changed position. It is to be remembered here that in Fig. 3 the rear wall of the lower lock case part 5B in Fig. 2 can be seen, that a key hole arranged in a symmetrical manner relative to the keyhole 7 for the same key as the keyhole 7 contains.

According to Fig. 3, in which only the bottom lock case part 5B 'and the adjacent part of the top lock case part 5 5A is shown, with a part of the lock plate 2, the insertion 7810278 7 is located.

> hole 8 for handle or handle for the dead bolt also substantially straight under the insertion hole 6 for the actual operating device - handle or handle etc. - for the latch bolt. Here, therefore, the design was realized as a toilet or bathroom lot.

5 The operating and movement mechanism for the dead bolt, which mechanisms are largely fitted in the upper lock case part 5A, are designed in such a way that the dead bolt is inserted by inserting a key into the keyhole 7 as well as by inserting a lever or handle etc. the plug hole 8 and the subsequent turning of the key 10 or latch can be effectively operated. The manner in which this can be solved mechanically is not a problem for the skilled person in the field. According to the invention it is only important that when the key is turned in the keyhole 7 or in the latch of the actuating and moving mechanism for the dead bolt inserted in the insertion hole 8, an active part from the lock case part 5B acts up to intervention occurs in an active part of those mechanisms in the lock case part 'pA. In its simplest form, this operative engaging portion from the lower lock case portion 5B may be, for example, the key's beard. However, it can also be a lever or pawl actuated by turning a key, i.e., by the beard.

In Hg. You can see molded and mutually interlocking profiling and securing means on both lock case parts, which consist of 25 grooves - and ribs - 15 and 16 formed in the direction transverse to the front plate 2 (see fig. 2). - and top edges of the side walls of the top and bottom lock case parts. It is clear that through this connection the two above-mentioned positions of use for the lower lock case part 5B and 5B 'according to Figs. 2 and 3 can be realized.

FIG. 5 finally shows a sliding plate 17, which is provided with rib profiling along the two longitudinal edges, which engage in groove profiling along the rear edge of both side walls of the top lock case part 5A. The slider inlet 17 can thus be slid down from the position shown to behind the rear edges of the side walls 35 of the lower lock case part 5B and 5B 'respectively, so as can be seen from FIG.

7810278 Secure the retracted position of the bottom lock case section with respect to the top lock case section 5A.

The cover plate 17 may of course also be provided with a stop, which co-acts with a counter-stop on, for instance, the top-5 lock case part 5A to ensure that the cover plate 17 does not come out with the rib profiles 18 engaging in the groove profiles 19 position may slide too far down or even fall out, which would make the locking of the lower lock case parts 5B and 5B 'illusory.

It will be clear that with respect to the embodiment described above and shown in the drawing, and in particular also the manner of subdivision and the cooperation to detachably fasten the two lock case parts within the scope of the invention. to be possible.
