Description

A LOCKING DEVICE FOR WINDOWS AND DOORS

Technical field:

This invention relates to a device intended to prevent the unwarranted open ing of windows, doors or other openable building elements. The device is designed to be able to be fitted or be fitted into a first element, for example a door-frame,or window-frame, and is thereby intended to be able to be in operation as a preventative device against opening, removal or the like of a second element, for example a door, a window, a casement, a frame, frames or similar which is arranged in the first element. The device is thu arranged to be able to be provided with or be provided with at least one lock, preferably a cylinder lock with a locking cylinder, by means of which the device can be locked.

Background:

There is a need of a device, preferably a lockable device, that can prevent an unwarranted opening or removal of an openable window or door regardless of access to, or unwarranted procurement of access to the window or door's existing opening catch and eventual lock, and likewise unwarranted unhookin of window casements or doors from their window-frames and door-frames respectively, especially for windows and doors with externally accessible hinges. There is also a need to be able to lock espagnolettes at such windows and doors provided with espagnolettes. These above mentioned needs exist for both the production of new windows and doors and for existing windows and doors.

Technical problems:

For doors there are, as is known, a number of well known locks whose principle construction could also be adapted to suit many types of windows. Common for all these locks is, among other things, that they easily can be broken open depending on the choice of material and that the locks are arranged in a handle, which provides a notch and a grip on the lock for breaking them open, in addition they are expensive but above all they canno prevent unwarranted unlatching of the window or door from their window- frames and door-frames respecitvely by removal of the hinge pins. Further, a known door can be opened if there is access to the key, whereby windows can then be opened from the inside. However suggestions have been made for special devices for locking windows or at least for making it difficult for unwarranted window opening. These devices are however accessible from the

inside of the window or if for example the window pane is broken from the outside.

There are previously known bolts for holding a sash in a certain position in windows and doors or when a storm sash is arranged. These bolts have in common the fact that they are completely accessible for manoeuvring or damage and can be manceuvered, removed or destroyed with a simple tool.

The solution: By means of a device according to this invention the requirements specified can however be met whilst the disadvantages of know devices can be elimin¬ ated. Thus, among other things, the window casement or.door can be arranged so that the window casement or door cannot be opened or removed from the window-frame or door-frame respectively regardless of whether or not the window or door's existing lock or opening catch can be unlocked or manoeuv¬ red. For windows and doors with espagnolettes the espagnolettes are locked via the device, whereby such windows and doors should not require any addit¬ ional locks to fulfill the requirement of being lockable. The device, which is hidden and protected and built-into for example a window-frame or door- frame, can be lockable both from the outside or inside of a building or from both sides of windows and doors._,Further, the device can be adequately dimensioned, is simple to manufacture and can be manufactured at low cost or at a cost so low that the device hardly effects the price of the window or door. It is possible to fit the device to all types of windows and doors regardless of if they are existing, in use or to be manufactured. The device is characterized hereby, in that the device, which can, include or shall include a lock, in itself is a lock and comprises a housing and at least one bolt and a driving device, which in the housing is arranged in engage¬ ment with the bolt and is in connection with said lock, that the device can comprise, comprises or shall comprise for locking the device. This lock forms a manoeuvring device for the device and is manoeuvred by means of a key belonging to the lock. Further, this lock is intended to manoeuvre the device in such a manner that the device, from an unactivated position shall be able to take an activated position or vice versa. Hereby said bolt is brought into engagement with the second element respectively is withdrawn from engagement with said second element.

The aforementioned lock of the device, as for other parts of the device, such as the driving device, bolt or bolts, as the device can include two bolts for engagement with two second elements, are arranged in intended positions in a housing in the form of a body.

According to an another characteristic for the device in accordance with the invention, the first element is in the form of a door-frame or a window- frame and the second element is in the form of a casement, frame or frames or similar or an espagnolette in a frame, whereby the casement, frame or frames or similar or the espagnolette shows or is provided with a recess, hole or similar, in which the bolt or bolts of the device can engage.

When the device is activated and the bolt of the device engages in for example the espagnolette, the window or door's opening or turning catch cannot be used to open the window or door as the espagnolette is locked.

Best odde for carrying out the invention:

Reference designation 1 shows a device in accordance .with the invention, that is intended for fitting into a first element 2, preferably a window- frame or door-frame, in order to be activated and thereby with a bolt 8 or when fitted into for example a mullion, with two bolts engaged in a second element 3 or two second elements 3, preferably a window, a door, a casement, a frame, frames or the like or an espagnolette arranged in a window or door casement or frame. The device 1 is arranged in a door-frame or window-frame 2 in that side of the frame facing the opening in the wall of the building and thereby in a recess 11 in the frame, see Fig. 3. Into the recess 11 is made an opening 7 or a hole through the frame to allow entry of a key to a lock of the device. In the recess 11 a hole 6 is made or in the case of two bolts 8, two holes 6, which shall lead to or preferably be opposite the second element 3 or that element which will be locked, obstructed or like¬ wise, for example a door or a window casement, whereby the bolt 8 can be entered into engagement with the second element 3 or into a recess, hole, opening or similar in the element. For the example according to the diagrams is arranged at least one device 1 in a window-frame 2 to a window or case¬ ment thus suspended at one side with hinges 5. For a horizontally suspended window or a so called pivot window two devices 1 are arranged between the axle 5 of the window and the lower part, that is provided with an opening or turning catch 4. Hereby can a device 1 when activated engage with its bolt 8 in the frame 3.

The device 1 includes a housing 12 in the form of a body of suitable mate¬ rial, such as plastic, nylon, neoprene, etc. The housing has one or two through holes 16 or channels for receiving bolts 8 and an aperture 17, space or hole to receive the other mechanisms 9, 14, 24, 30 of the device 1. In the recess 11 a hole 6 and an opening 7 are arranged to correspond with the hole 16 and the aperture 17 in the housing 12. Further, the hous¬ ing shows a number of through holes 19 for eventual securing of the hous¬ ing in the element 2 and a securing arrangement 21 in the form of holes for /0022

a securing element. The housing 12 is thus recessed in the element 2 but when the device 1 is utilized for engagement in an espagnolette 25 the device or housing cannot be situated too deeply into the element 2. There¬ fore the housing can show protruding parts or ears 20, by means of which is ensured that the housing cannot be removed from the element 2 if element 2 should be subjected to damage to gain access to the device. When utilized for engagement with an espagnolette the holes 16 are situated as near as possible to the front of the housing 12. Should the device be utilized for engagement with another second element 3, for example- an external frame, the device can either be arranged further in in the element 2, whereby a simpler design of housing 12 can be utilized and without ears 20, thus per¬ mitting a simpler and quicker working operation when producing the recess 11, Fig. 22 shows such a recess 11 in the frame 2, or that the holes 16 in the housing 12 are situated further in in the body, see the alternative embodiments shown, whereby this is perhaps best seen by the example in Fig. 23. The holes 19 and the opening to the aperture 17 can be countersunk, see reference designation 13 in Figs. 19 and 5 respectively.

An alternative design of housing 12 is shown in Figs. 6 - 7, where the hole 16 or the holes are provided with a bush 18, sleeve or the like, which is arranged to receive a bolt 8. The diagrams show a housing arranged to re¬ ceive one bolt. Further, it can here be clearly seen that the aperture 17 shall be open or allow entry into the holes 16 or channels. According to the embodiment shown, the bush 18 thus show a recess or an aperture 37 for communication between the hole 16 and the aperture 17 in the housing, see Fig. 8.

An embodiment for a bolt 8 is shown in Fig. 9 where the bolt shows an engag¬ ing device 22, for example in the form of a number of equi-spaced parallel grooves, a screw thread or a cylindrical gear, plus an engaging portion 38 for engagement with the second element 3. The engaging portion 38 can be of cylindrical shape or for espagnolette engagement preferably square shaped to obtain a stronger engagement.

In the aperture 17 in the housing 12 a driving device 9 shall be arranged that shall engage with the bolt 8 or bolts. In Fig. 10 is shown an example of a driving device in the form of a sleeve or a tube with engaging device 23 for engagement with the bolt's 8 engaging device 22. According to the example the engaging device 23 has teeth. The example shows a design for

the bolt and the driving device .rather like a worm gear with bolts like a worm screw and with the driving device like a worm wheel. The reciprocal function is like that of a worm gear or a gearing. When utilizing two bolts these are made to protrude in their respective directions from within the housin .

The device 1 can or shall be lockable, whereby a lock 14 shall be or is fitted in the housing 12. The lock 14 can here be in the form of a cylinder lock with a locking cylinder 24 with a locking arrangement 27 in the form of for example locking pins or tru blers, see Fig. 11.. The lock is acti¬ vated with a key 26. The lock 14 shows a securing device 29, for example in the form of a threaded hole or a recess for securing of a connector 28 or a carrier. The fact is that the lock 14 shall be arranged in a reciproc¬ ally rigid connection with the driving device 9, which in the same manner shows a securing device 34 in the form of for example a threaded hole or a recess for securing the connector 28 or the carrier.

For engagement of the lock 14 or its locking element 27 there is an engag¬ ing element 30 in the device with the function in reality of acting as a control or stopping device for a manoeuvring device and limits the rotation of the manoeuvring device between an activated and an unactivated position of the device 1, i.e. when bolt 8 is engaged with a second element 3 or withdrawn from such an engagement respectively. An example of an engaging element is shown in Figs. 12 - 13, where it can be seen that recesses 31 or the like for locking elements 27 of the lock 14, which when the device 1 is locked, thus protrude into the recess and obstructs against the walls 35 of the engaging element. Further, the engaging element shows an opening 32, groove, slit, recess or the like, through which the connector 28 or carrier can reach. The walls 35 of the opening 32 or the like provide here a stop for movement of the manoeuvring device or lock 14, or according to the example the rotary motion or the the activated and unactivated positions of the device 1. The engaging element 30 receives the lock 14 and is in the form of a sleeve or similar and shows an anchoring device 33, for example in the form of a hole through the walls of the sleeve, whereby the engaging element 30 can be anchored in a fixed position in the housing 12. The driv¬ ing device 9, which in the device 1 shall be arranged at an axial distance from the lock 14, is arranged co-axially around the engaging element 30, see Figs. 17 - 18, which show lock 14, driving device 9 and engaging ele¬ ment 30 arranged as a single unit and in Fig. 14 arranged in a housing 12 with a bolt 8. It is important that said unit is built-in and positioned by a body or a housing 12 according to the invention, so that the parts 9, 14, 24, 30 are arranged in the correct relative positions and that the unit is secured in the correct position in relation to the bolt 8 in order to achieve a satisfactory function and durability for the device. Another of the engaging element's functions is to hold the lock in the device, which is achieved through the connector's engagement with the engaging element. When the device is unactivated the lock's locking elements are pressed against the inner wall of the engaging element at the side of the recess.

The lock 14, which is intended for the fact that the device 1 shall be able to be locked, is a manoeuvring device or is said manoeuvring device for the device 1 and is manoeuvred with the key 26, whereby the device is manoeuvred via the lock and manoeuvred between the activated and unactivated positions of the device.

In Fig. 19 is shown an embodiment for a device 1 in an unactivated position, whereby when turning the manoeuvring device or lock 14 with the key 26, the rotary motion and the manoeuvring is transmitted to the driving device 9, which, by means of the engagement of the engaging devices 23 with the engag¬ ing devices 22 of the bolt 8, displaces the bolt into engagement with the second element 3, for example by passing through a hole 10, opening, recess or the like. Said second element can be provided with a bush to receive the engagement portion 38 of the bolt 8. The device 1 can be placed on any side whatsoever of for example a door-frame or window-frame as the bolt 8 can be arranged to project from either side of the housing 12, whereby the bolt can be arranged in either of the holes 16 or channels according to the other shown embodiments of the housing and devices, or as mentioned allow bolts 8 to project on both sides of the housing for engagement with two second elements 3.

The device 1 can also be arranged for two locks 14, whereby one of these locks is utilized from the outside of a building or from one side of a door or window while the other lock is utilized from the inside of the building or from the other side of the door or window. Hereby the locks 14 can be of the same type or arranged for two different keys.

As has been seen from the embodiments the engaging element 30 shows a length that exceeds the length of the manoeuvering device or lock 14 or its locking cylinder 24 and driving device 9. This even applies when lock 14 or locking cylinder 24 is provided with an extension 40 to the locking cylinder, which by means of an anchoring device 39 is anchored in the lock or locking cylinder. Such an extended engaging element 30 can be utilized when the driving device 9 or the housing 12 are to be positioned deep in the element 2, in applicable cases be provided with two driving devices for the engagement of the device with two second elements 3 placed after each other, for example with both frames of a window in paired frames, and event ually when using double locks 14, etc. Fig. 24 shows^"such an extended engag ing element for an extended manoeuvring device or lock.

In Fig. 20 is shown a device 1 in accordance with the -invention for engage¬ ment with an espagnolette 25. The espagnolette is here shown with a recess 36, hole, opening or similar for the engagement and obstruction of the espagnolette by the bolt 8. Hereby, the second element 3 has in the usual manner a recess 10, hole, opening or similar for the engagement of the bolt 8, but in this case for the passage of the bolt to the espagnolette. The bolt also passes through the space 41 between the first element 2, or the door-frame or window-frame, and the second element 3, or the frame.

Without exceeding the scope of the concept of the invention, modifications to the device in accordance with the invention should be possible. Thus, the housing can be of another design, as also the bolt and driving device and theirs engaging devices. The lock can be of another type even if a cylinder lock can be considered as being the only suitable type for simple construction and manoeuvring of the device. The areas of application for the device, which is in itself a lock, are extensive and the use in build¬ ing elements is only one example of areas of application and of uses. The device is thus not restricted to that shown and described in connection with the embodiments but soley by the following claims.
