Abstract
The invention relates to a novel safety device for a locking device that is actuated manually using an actuating element and is used for doors and/or windows. The invention is characterised in that the safety device only permi ts the actuation of the locking device, if a force equal to or greater than a p re- defined actuation force is exerted on the actuation element (2, 2a, 29, 52). Said actuation force can be set in such a way that it cannot be exerted by a child. The safety device is designed to be activated and deactivated.</SDOAB >
Description
Safety device, for example a child safety lock and a locking device comprising a safety device of this type The invention relates to a safety device, especially child safety for a closing device for windows and/or doors in accordance with patent claim 1, specifically to a safety device for bulling windows and/or doors as well as vehicle doors, especially car doors, to be used as child safety.
It is the task of the invention to present a safety device which combines a simple design with the ability to reliably secure closing devices, for instance of window and/or door fittings or locks, against unauthorized operation.
In order to solve this task, the safety device has been designed in accordance with patent claim 1. A closing device has been designed in accordance with patent claim 26.
The safety device as per the invention can be part of the window or door fittings, e.g. at a window or door handle, and/or part of a window or door lock and/or part of a latching device or a lock for vehicle doors.
All types have one thing in common. After the safety device has been activated, operation of a door and/or window latch or a window or door lock is only possible with or after overcoming a pre-set force or a pre-set momentum (operating force). This operating force is adjustable or adjusted in such a manner that it cannot be easily opened by children or under manipulation from the outside, i.e. the safety device as per the invention on the one hand is a simply constructed but very effective child safety, on the other hand the protection against break-ins at windows, doors, etc. is significantly improved through the safety device as per the invention.
The safety device of the invention is designed in such a manner that it can be deactivated and activated, for instance by changing the operating force or characteristic force curve which is required for the operation of the applicable fitting, lock, etc.
While maintaining existing construction principles, the invention can be integrated into existing industrial fittings, handles, locks, etc. in a simple and therefore cost-effective manner. This fact as well as the simple design and operation of the safety device as per the invention thus provide the prerequisites for equipping standard fittings with a reliable safety device, especially also with a perfect child safety, without requiring extensive changes in construction and without negatively impacting upon the proven functions of standard fittings.
The invention specifically offers the opportunity to perfectly adjust the existing safety device at each door and/or each window individually in accordance with the applicable requirements and situations, for instance in regards to the age of the children. The applicable adjustment of the operating force may occur via the setting of the spring strength, via an adjustable pneumatic or hydraulic or other media, even via flexible elastic materials such as rubber or synthetic materials, polymeres, etc. The access and operating points for the adjustment of the operating force are intended to be located at easily accessible positions.
The safety device as per the invention is designed in such a manner as to require a certain operating force in accordance with an adjustable force curve for operating the applicable latching devices or the applicable lock. The adjustable force curve may be omitted and replaced by a special pre-set force or pressure point, which must be overcome in order to operate the secured latching device or the secured lock andlor to deactivate the safety device. This pressure or force point may be realized in different ways, for instance via arrester elements, springs, etc.
A further advantage lies in the fact that after activation, the child safety remains in a constantly active state, which makes manipulation by children impossible, as opposed to commonly used child safeties in car doors, which are activated or deactivated by engaging a lever, which can be accidently engaged by a child as well, at least in cases where the car is immobile and the door is open.
A further essential advantage lies in the fact that due to its simple design, the child safety can be integrated into car locks of a variety of vehicle types without requiring extensive _2_ changes in construction.
The invention also has the advantage of being of simple, constructive and thus reliable construction. The invention avoids failure-susceptible components as well as components which are easily damaged, especially in case of accidents, specifically electrical and electronic components, which makes it fully function in just about any situation.
Further developments of the invention are subject to sub-claims. In the following, the invention is illustrated using images of design examples:
Image 1 A window handle of the invention in simplified and side view Image 2 An illustration similar to image 1, however after removal of the cover element from the handle Images 3-5 The window handle of image 1 in a view of the reverse of the cover, with different positions of the handle regarding the cover element Images 6-8 A further design variation of the window handle as per the invention with integrated child safety, shown in a simplified transverse section Images 9-11 Different uses of the window handle of images 1-8 as door handle, shown in a simplified transverse section Image 12 A front view of a door lock as per the invention Images 13-16 The door lock of image 12 with the lock case open in different states: in an unsecured state with the lock latch in both the locked and the open position (images 13 and 14), in a secured state with the lock latch in both the locked and the open position (images 15 and 16) Images 17-20 Illustrations equivalent to images 13-16, using a modified design Images 21-25 A simplified illustration of a car door lock in closed and open state with deactivated child safety (images 21 and 22) as well as in closed and open state with activated child safety (images 23 and 24) Images 26-28 Another possible design variation of the car door lock as per the invention Images 29-32 Different illustrations of additional possible design variations of the door and window handle as per the invention Image 33 A front view of a door lock as per the invention Images 34-39 The door lock of image 33 in side view and in different states Image 40 Different illustrations of a lock latch to be used with the lock of images 33-39 Images 41-45 Various additional possible design variations of the window handle as per the invention, shown in a simplified view Images 46-49 Different illustrations of a turning handle for a lock with latch and child safety Images 50-53 Different designs of a door knob of a door lock with child safety Image 54 An illustration similar to image 34, showing another possible design variation of a door lock with child safety In these images, 1 is a window handle which consists of the commonly known handle element or handle body, made for instance of plastic, which, for the design variation illustrated, is represented in image 1 as a flat U-shape and which is placed in a swiveling position with circular cylinder-shaped section 3 into a groove of a cover or covering collar 4.
The covering collar 4 is fastened in the usual fashion to the interior surface of a window wing, which is not represented here. In addition, the handle body 3 possesses at its end at section 3 a square S-shape, which extends beyond that end. This is used to connect the installed window handle 1 in the usual fashion to the closing mechanism mounted in the window wing for the purpose of operation. At its circumference, the section 3 is equipped with several groove-shaped gaps 6, specifically in the design variation illustrated, with four gaps 6, equally distributed around the axis of tha square 5. In addition, the covering collar4 contains a flexible arrester element, which in the design variation shown, is formed by a sphere 7.
This sphere 7 supports the end of a pressure spring 8, whose other end touches an adjusting element 9. The latter is formed by a nut sitting on a threaded bolt, which is positioned in a gap of the covering collar 4 to allow it to turn but not to move axially. The axis of the threaded bolt 10 is radially positioned to the axis of the square 5. The nut 9 can be moved axially, but not turned. The gaps 6, the sphere 7 and the pressure spring 8 form the child safety 11.
The pressure spring 8 flexibly presses the sphere 7 against the circumference of section 3 and arrests in pre-determined positions of the window handle 1 into one of the gaps 6, which may be equivalent to the closed or tilted positions of a window. Using four gaps 6 allows the window handle 1 to be used both on the right-hand and the left-hand side of a window or window wing. The spring 8 is, at least partially, supported by the threaded bolt 10. Through the use of suitable tools, for instance a screwdriver, it is possible to turn the threaded bolt and thus adjust the pressure generated by the spring 8 in such a manner that after the arresting of the sphere 7 into a gap 6, a turning of the window handle 1 and thus operation of the window fitting, for instance to open the window, is only possible after overcoming an operating force which cannot be accomplished by a child. Thus the settings of the tilting position of the handle element 2 as defined by the gaps 6 are secured against unauthorized operation by a child with the help of the child safety.
It is understood that the window handle 1 can also be used as a handle at a door lock, for instance at a door lock of a bulding door, for instance an interior building door. In this case, the square 5 is guided through the door in the known fashion, and a matching handle element is fastened to the end of the square 5 at the side of the door wing which is facing away from the handle element 2.
The design variation illustrated in figures 1-5 thus achieves a characteristic force line with a rising ramp through the use of the child safety, that is through the sphere 7 arresting in the gaps 6. When the sphere 7 is arrested, this force must be overcome to operate the handle element 2.
As illustrated, the force of the spring 8 and thus the characteristic force line is adjustable.
If this is not desired or required, the covering collar 4 can be of the closed variety at its circumference. In this case, the spring 8 rests on the end facing away from the sphere 7, onto a closed side of a gap intended for admitting the spring 8 and the sphere 7. In the window handle 1, the integrated child safety is thus formed by the gaps 6 and the adjustable arrest working with those gaps, and includes the sphere 7, the spring 8, the threaded part of the nut and the threaded bolt 10.
The images 6-8 illustrate a further design variation; a window handle 1 a which is different from the window handle 1 in regards to the integrated child safety 23. In the window handle 1 a, the child safety is designed in such a manner that for an access-enabling connection with the window fitting, against the effect of a spring force from an initial position, in which an access-enabling connection is not present and the child safety is activated (image 6), the handle element 2 must be pushed into a position where the child safety is then deactivated (images 7 or 8).
The window handle 1 a has a covering collar 4a, in which the handle element 2 is flexibly positioned around the axis of the square 5 in a certain angle range. For a turning/tilting window, the wing 12 and the pane 13 of which are illustrated in images 6-8, this angle range is approximately 180° between handle positions, which corresponds to the closed position, the tilted position and the position for opening the window. The square 5 working with the turning, tilting and closing fitting has a carrier 15 near the covering collar 4, which is connected to the drive of the square 5 and which reaches into a gap 16 of the handle element 2a. One end of the carrier 15 has arresters 17, for instance in the shape of a circular outside togging around the axis of the square 5, which can work together with matching arresters 18 at the bottom of the gap 16. The arresters may have an inside togging.
Between the handle element 2a and the covering collar 4a, there is a reset spring, for instance a torsion spring 19, which pre-sets the handle element 2 in a pre-determined initial position, for instance in one of the two extreme positions of the turning movement of that handle element, in which (extreme position) the handle element stops against a reverse stop of the covering collar 4a. In addition to the reverse spring 19, a pressure spring 20 operates between between the handle element and the coupling piece 15 and partially enclosing the coupling piece 15, which places the handle element 2a in a position, in which the drive connection between the handle element 2a and the coupling element 15 is interrupted and which thus matches the state "child safety activated", as illustrated in image 6. In this position, the handle element 2a can be turned against the effect of the reverse spring 19 without engaging the window fitting 14.
In order to engage the window fitting 14, the handle element 2a must be pushed against the effect of the pressure spring 20 in the direction of the window wing, as illustrated by arrow K in image 7. The operating force required for this push, through the selection of the pressure spring 20, is selected in such a manner that this force can only be applied by an adult and not a child. Image 7 illustrates the state in which the handle element 2a has been pressed against the window wing in such a manner that the carriers or arresters 17 and 18 reach into each other, thus enabling the operation of fitting 14 by tilting of the handle element, while maintaining the push onto the handle element 2a. This provides the state "child safety deactivated".
The window handle 1a also provides for the option of fixing the state "window handle deactivated", as illustrated in image 8. The handle element 2a, i.e. in the case of the design variation illustrated, at the edge of the opening of gap 16, has a circular arrester 21, which reaches into a circular reverse arrester 22 on the coupling element 15, if the handle element 2a is pushed beyond the state illustrated in image 7 in the direction of the arrow K into the opening of the covering collar 4a, i.e. in the direction of the wing frame.
By pulling in the direction of the arrow K, using a pre-set force which can be adjusted by selecting spring arrester 21 or 22, the handle element can be re-positioned from the state of image 8 to the state of image 6.
The integrated child safety 23 for the window handle 1a is therefore mainly formed by the coupling element 15 with the coupling section 17 and the handle element 2a with the coupling section 18, which can be moved relatively to the coupling element 15 in the direction of the axis of the square 5 and against the effect of the pressure spring 20.
Image 9 illustrates the use of the handle 1 a as a door handle at a door 12'.
For this use, the square 5 is guided through the door 12' and the door lock in the known fashion, so that a further handle element 2a can be fastened to the square 5 on the side of the door 12' which faces away from the handle element 2a'.
The variation illustrated in image 9 provides for a child safety 23 at one side of the building door 12' only. The functionality of the child safety 23 is identical to the function as described above in connection with images 6-8.
The variations illustrated in image 10 provides for a handle 1 a with matching child safety for each side of the building door 12'.
_g_ Similar to image 6, image 11 illustrates a handle 1 b which is different from handle 1 a in that it has a pressure spring 20b instead of the pressure spring 20, whose spring force is adjustable. This is done via a threaded rod 20b which is guided in a threaded nut piece, for instance in a nut 20b" in the handle element 20 b. The threaded rod 20b' provides the support to one of end of the spring 20b, whose other end is supported by the coupling piece 15. The threaded bolt 20b' is accessible for adjusting the force of spring 20b at the side of the handle element 2b facing away from the square 5, and should be covered by a suitable cover.
Images 12-16 illustrate a door lock 24, whose lock case 25 containing the functional elements of the door lock 24 can be fastened in a lock case opening at the groove side of the door in the usual fashion, so that the plate 26 is located in the groove of the door wing and that the lock is secured in the lock case opening of the door via this plate and through the use of screws. In the design variation illustrated, the lock 24 has a key-bolt 27 operated by a key as well as a flexible lock latch 28, which can be moved from the closed position, in which the lock latch 28 extends out of the lock case and beyond the plate 26, to an opening position via an eyelet 29 flexibly positioned in the lock case 25 and a lever 30 radially positioned at this eyelet. The eyelet is equipped with a square opening 31 in the known fashion, into which the square not illustrated of the door handles also not illustrated reaches.
The lock 24 is equipped with an adjustable child safety. This is generally identified as 32 and consists of a double-armed turning lever 33, which can be moved around an axis parallel to the axis of the eyelet 29. One end of the turning lever 33 has a pressure lever 34, whose other end is freely supported by a support point formed at the transition between the eyelet 29 and the lever 30. The other end of the lever 33 has a support element 35, which mainly consists of a plate and a peg positioned at the free side of this plate. This support element 35 supports one end of a pressure spring 36, whose length extension is basically radial to the length extension of the lever 33, in a mutual plane with the length extension of this lever, said plane being vertical to the plane of the axis of the eyelet 29. The other end of the pressure spring 36~is supported in the area of the lock plate 26 by an adjustable support, specifically a threaded nut piece 38 of this support. The threaded nut piece 38, which in the design variation illustrated is formed by a hexagon nut, rests on a threaded bolt 39, whose positioning at the lock plate 26 allows turning but no axial movement, and which is accessible at the outside of the lock plate through the use of a suitable tool such as a screwdriver, so that by turning the threaded bolt 39 and the resulting movement of the threaded nut piece 38 along the threaded bolt 39, the pre-set force of the pressure spring 36 can be set. Since the threaded nut piece 38 is supported by the end of the pressure spring 36, the threaded nut piece 38 is held into place by this pressure spring without any danger of turning. In addition, the design ensures that when turning the eyelet 29 into the open position as part of the movement of the lock latch 28, the lever 33 is turned via the pressure lever 34 in such a manner as to allow an additional setting of the pressure spring 36.
In images 13 and 14, the pre-set force of the pressure spring 36 is set in such a manner that a relatively easy turning of the eyelet 29 and thus a relatively easy moving of the lock latch 28 from the closed position (image 13) to the open position (image 14) is possible. The threaded nut piece 38 is located near the lock plate 26.
Images 15 and 16 illustrate the state in which the pressure spring 36 is pre-set to the extent that moving the eyelet 29 via the applicable door handle and thus moving the lock latch 28 from the closed position (image 15) to the open position (image 16) is only possible after overcoming a relatively large operating force or a relatively large momentum, which ensures that the door cannot be opened by a child. This means that images 13 and 14 illustrate the state "child safety deactivated", while images 15 and 16 illustrate the state "child safety activated". The threaded nut piece as shown in images 15 and 16 displays a considerable circumstance from the lock plate 26.
In the lock 24 the child safety 32 installed in the lock case 25 is mainly formed by the levers 33, 34 and the adjustable pressure spring 36, the latter being located in the lock case above the latch 28. 14 refers to a leaf spring, which among other things is used to pre-set the lock latch 28 into the closed position in lock 24.
Images 17-20 illustrate another possible design variation, a lock 24a whose only differences to lock 24 are the fact that the pressure spring 36 is located in the lock case 25 between the eyelet 29 and the key-bolt 27 and that the lever-33-equivalent lever 33a works on one end with a stop 42 via a spring 41 in the area of operation 33a', which is provided for on the lock latch 28 or its latch slider 28' and onto which the lever 30 of the eyelet 29 also impacts. The other end of the lever 33 touches the end of the pressure spring 36, whose other end is supported by the adjustable support 37. The pressure spring 41 serves as reset spring for the latch 28. When tilting the eye 29 over the door handle not illustrated, the latch 28 is moved back from the closed position to the open position via the lever 36 touching the stop 42 by tighening the pressure spring 41 or 36.
The pressure spring 36 is significantly harder than the pressure spring 41.
The pressure spring 36 can be pre-set in different ways due to the adjustable support 37.
Images 17 and 18 illustrate the state "child safety deactivated". The pressure spring 36 is not or only slightly pre-set. The threaded nut piece 38 is this in the vicinity of the lock plate 26. When engaging the eyelet 29, the lock latch 28 is moved from the closed position (image 17) to the open position (image 18), simply by reshaping the pressure spring 41.
Images 19 and 20 illustrate the state °child safety activated", in which the pressure spring 36 is suitably pre-set and the threaded nut piece is thus located at a distance from the inside surface of the Jock plate 26. Since the pressure spring 36 is significantly harder than the pressure spring 41, the latter is pushed together so far that the lever 33a with its hook-shaped angular end 33a' directly touches against the stop 42, even when the latch 28 is in the closed position. The tilting of the eyelet 29 and thus the moving of the latch 28 from the closed position (image 19) to the open position (image 20) is therefore only possible upon overcoming a relatively high turning momentum generated by the force of the pressure spring 36. The selection of the pressure spring 36 and/or the setting of the pressure spring are such that this cannot normally be done by a child. In the door lock 24a, the adjustable support 37 or its threaded bolt, which is used for the pre-setting of the pressure spring 36, can be accessed from the outside of the lock plate 26.
Images 21-24 illustrate a very simplified view of a car door lock 44 with a tiltable key-bolt 46 provided for at the lock case 45 of the door , which works with an applicable counterpart at a fitting of the vehicle so that the tilting positon of the key-bolt 46 illustrated in images 21 and 23 reflects the closed car door and the tilting position of the key-bolt 46 illustrated in images 22 and 24 allows the car door to be opened. The tilting of the key-bolt 46 occurs via a hinged axis 47 which is located in the lock case 45.
Via a pressure spring 48, which works between one end of a key-bolt lever 46' radially positioned from lever 46 and a plate 49 of the lock case 45, the key-bolt 45 is pre-set in the closing position. The pressure spring 48 is supported by the plate 49 via an adjustable support 50, which is equivalent to the design of the adjustable support 37 and on which the pre-setting of the pressure spring 48 can be performed from the accessible side, for instance from the outside when the vehicle door is open.
On the inside of the vehicle door, a lever 52 is flexibly positioned in a casing 51, which is connected to a key-bolt 46 via a rod structure 53. Thus when the lever 52 is tilted from its initial position, in which the lever 52 is located in the casing 51 (images 21 and 23), and into a position where the lever 52 extends beyond the casing 51 (images 22 and 24), the key-bolt 46 is moved from the closed to the open position.
Images 21 and 22 illustrate the state "child safety deactivated" in which the pressure spring 48 is only slightly pre-set and thus a tilting of the key-bolt 46 from the closed position (image 21 ) into the open position (image 22) is possible with only a small amount of force.
Images 23 and 24 illustrate the state "child safety activated" in which the pressure spring 48 is suitably pre-set so that only when a force is applied which cannot normally be applied by a child, the key-bolt 46 is moved from the locking position (image 23) to the open position (image 24) by tilting the lever 52.
Images 25-28 illustrate a further possible design variation, a door lock 44a, which is different from the door lock 44 in that the pressure spring 48a, whose function is equivalent to that of the pressure spring 48, works between the casing 51 and the lever 52 and is provided for at the reverse of the casing 51. The pressure spring 48a is supported between a projection 52a of the lever 52 connected to the rod structure 53 and an adjustable support 50a, which is provided for in the area of the trough-shaped depression of the casing 51 and which is accessible via this depression.
Images 26 and 26 illustrate the state "child safety deactivated", in which the pressure spring 48a displays only a slight pre-setting. Images 27 and 28 illustrate the state "child safety activated where the pressure spring 48a is more strongly pre-set.
The car door locks 44 and 44a with child safety as illustrated in images 21-28, compared to commonly used child safety devices, have the advantage of allowing the applicable car door to be opened by an adult at any time, especially in case of an accident, thus enabling speedy rescue.
The previous paragraphs were based upon the assumption that the force of the springs 48 and 48a is manually adjustable with the help of the setting elements 50 or the setting screw.
However, there is another general option to perform the setting of the spring force mechanically via actuators, which may be operated via an operating element which is accessible in the area of the driver's seat, for instance an operating element included in the dashboard. Like the other variations, the following also applies to this variation: even when the child safety has been set to the strongest setting, i.e. the applicable spring element is set to the strongest spring force, this force cannot be applied by a child, but can be easily overcome by an adult in case of emergency so that in case of an accident, the door can be opened by an adult. This also means that the possibility of opening the car door by an adult with the child safety activated does not depend on the faultless functioning of any electronics.
Actuators for the mechanical setting of the spring force are for instance electrical or electromagnetic actuators such as actuators or motors based upon magnetic force. Other actuators such as hydraulic actuators are also possible. The applicable actuator is integrated for instance in the lock area or in the area of the door handle.
Unlike the special design variations illustrated in the images, the spring-type elements can naturally be provided for at another suitable location as well, for instance in the area of the rod structure between the door handle and lock. Instead of the springs 48 and 48a, other elements acting as springs may also be used, for instance those made of plastic and/or metal.
Images 29 and 30 illustrate another possible design variation, a window handle 1c, which is similar to the window handle 1 and whose covering collar 4c has two spring elements 60, whose spring force is adjustable and who work with groove-type gaps 6 at the section 3 of the handle element 2c. The spring elements 60, which are positioned radially to the axis of the section 3c or the square 5 of the handle element 2c and facing each other diametrally, consist of sliding piece 61, which can be moved in a guiding rail of the covering collar 4c in the axis direction A and which has a sphere 62 on the side facing the section 3c which works with the gaps 6. Supported by this sliding piece 61 is a pressure spring 63, whose radial outside end touches a reverse stop 64, which can be adjusted with a screwdriver via a screw-bolt 65. Through the use of the four gaps 6, the window handle 1 c has a total of four arrester positions, three of which are used by a window with a turning/tilting fitting when installed (either left or right installation). If the force of the springs 63 is set accordingly, the child safety at every arrester position is achieved in such a manner that the window handle 1 c or its handle element 2c cannot be operated by a child, since only an adult is able to apply the force required for overcoming the arrester generated by the springs 60.
Images 31 and 23 illustrate in a view like image 29 and 30 a door handle 1d, which is different from the window handle 1 c in that the handle element 2c does not have the groove-type gaps 6 in its section 3d which reaches into the opening of the covering collar 4d.
Instead it has two wing-type projections 66 forming two lifts or ramps, which work with the spheres or the flexible sliding pieces in such a manner that the door handle can only be opened if the flexible sliding pieces are simultaneously moved radially to the outside against the force of the pressure springs through the ramps or projections 66. In this case the two pressure springs can also be adjusted so that the force for opening of the door can only be applied by an adult but never by a child. The ramps formed by the projections 66 can be shaped in such a manner that a continuous force increase, depending on the tilting angle of the handle element 2d is achieved, which results in an especially comfortable operation.
Unlike the design variations described, the child safety can also be achieved by providing for a push button on the handle element, which when engaged will release a child-safety blocking and enable the applicable handle element to be tilted. In this case the push button is also pre-set via ad adjustable spring force so that this spring force cannot be overcome by a child but only by an adult.
Images 33-39 illustrate another possible design variation of the door handle 24b, which differs from door handles 24 and 24a in that a pull spring 70 is provided for in the lock case 25 for the child safety. One of its ends is held by an adjustable support 71, accessible via the lock case plate 26, and its other end impacts upon the extension 30b' of the eyelet lever 30b, whose function is equivalent to that of the eyelet lever 30, i.e. which serves for engaging the lock latch 28b or the lock latch slider 28b against the effect of the leaf spring 40.
In the extension 30b' there is a lengthwise slit 72, which is at a tangent or an approximate tangent to the supposed circle around the axis of the square 31 and into which the other end of the pull spring 70 is hooked. Depending on the setting of the adjustable support 71, which can simply be formed by a screw, on whose threading one end of the pull spring 70 or a threaded nut piece connected to the pull spring is held, the effect of the child safety formed by this pull spring is adjustable, i.e. the force required for opening the lock latch is adjustable between the value Zero and a maximum value.
Images 34-36 illustrate the state in which the pull spring 70 is without effect or the child safety is turned off. Images 34 and 35 show this with the lock latch 28b extending beyond the lock case plate 26, and image 36 with the door handle pushed and the latch 28b moved back into the lock case 25. Images 37 and 38 illustrate the setting of the pull spring 70, for which (setting) the pull spring is guaranteed to be effective if the door handle is completely pressed down or if the lock latch 28b is completely pulled in. Image 38 illustrates a setting in which the pull spring 70 is already effective during the quiescent state of the lock, i.e. when the latch 28b is extending beyond the lock case plate 26.
Image 40 shows different views or positions a - h of the lock latch 28b and the matching latch slider 28b'. As illustrated, the actual latch 28b is removably fastened to the latch slider 28b' by a screw 73, which is accessible via the free end of the lock latch 28b and thus from the outside of the lock case plate 26. In addition, the latch slider 28b' and the lock latch 28b are designed in such a manner that the latch 28b can be fastened to the front side of the latch slider 28b in two positions which are turned at an 180° angle from the length of the slider 28b. Thus the door lock 24b can be used for left- or right-controlled doors. Both fastening options of the lock latch 28b to the latch slider 28b', in addition to the connection via the screw 73, achieve a form-locking connection between those elements.
The door lock 24b, when compared to the door lock 24, has the advantage that the spring force required for the child safety is not effected by an additional lever, but that the eyelet lever 30b is used for this in the manner described above. No basic changes are necessary for the integration of the child safety into the door lock 24b, compared to the commonly used design, which means that the child safety can be integrated easily into existing, proven constructions. In addition, the positioning of the pull spring 70 is extremely favourable from a mechanical point of view so that the pull spring 70 is easy to operate.
The connection of the pull spring 70 with the adjustable support 71 or with screw forming this support is realized for instance by the pull spring 70 reaching into the screw thread or by providing for a threaded sleeve or a threaded nut piece at the applicable end of the pull spring, which works with the screws.
The length of the lengthwise slit 72 is equivalent to the path or angle length, by which the eyelet lever 30b is moved when the door handle is completely pressed down or when the door handle is completely tilted.
A further, especially favourable characteristic of the door lock 4b is the fact that the leaf spring 40 is fully effective even when the child safety is turned off. Thus the standard function of the door lock remains unchanged, while the applicable setting of the adjustable support 71 results in the gradually adjustable effect of the pull spring 70.
By using the pull spring 70, the adjustable support 71 can also be easily formed by a screw, whose screw head (flat head) is held in a matching drill hole of the lock case plate 26.
As illustrated by images 37 and 38, the setting of the pull spring 70 may be executed in such a manner that at the beginning of the opening movement via the eyelet lever 30b, only the leaf spring 40 is effective, and only when the lock latch 28b is moved further back, the effect of the pull spring 70 is added.
A special advantage of the door lock 24b is the fact that the spring force of the lock latch 28b does not depend on the setting of the pull spring 70 and is determined by the leaf spring only.
When installing the applicable door into a building, major tolerance may occur so that when the door is closed, the lock latch 28b no longer reaches into the applicable opening of the lock plate with its entire length, but only with a portion of its length. In this case, a reliable child safety can still be achieved by the applicable setting of the pull spring 70.
Since th pull spring 70 directly impacts upon the eyelet lever 30b and no additional lever structures are required, the result is not a simplified construction but also a design with very little wear and tear.
The opening for the lock latch 28b in the lock latch plate is designed in such a manner that by turning the lock latch 28b a usage in either a left or right door wing is possible, while a reliable guidance of the lock latch 28b at the lock case plate 26 is still guaranteed. The positioning of the lock latch 28b, but also of the key-bolt 27 in the design variation shown are in the middle of the lock case plate 26.
Images 41 and 42 illustrate a simplified and reverse view of a window handle with a handle element 2a, which can be tilted on a casing 74 and has again the square 5. The casing 74 has two sides and consists of an outer casing part 75 and an inner casing part 76. The latter can be made of plastic or metal and has two drill holes 77 for the fastening of the window handle 1 a to a window wing. The outer casing part 75 which covers the inner casing part 76 like a dome, is also made of a suitable material, for instance metal or plastic. Both casing parts have a drill hole, in which the section 78 of the handle element 2e, which takes in the square 5, is positioned so that it can be turned. The circumference of the section 78 has arrester lifts 79, in the case of the design variation illustrated four such lifts, which work with an arrester 81 formed at a tilting lever 80. The arrester 81 is located on one side between the two ends of the tilting or arrester lever 80, whose one end can be tilted via a joint 82 at the inner casing part 76 within the building around an axis parallel to the tilting axis of the handle element 2e. Its other end works with one end of the spring 83, which is held by a screw 84 on the inner casing 76 so that the screw is accessible from the outside for setting of the spring force of the pull spring 83. Via the setting of the pull spring 83, the force required for the renewed tilting of the handle element 2a after the engaging of the arrester 91 in a groove 79 can be adjusted.
The handle element 2e can be connected to the casing 74 in different ways. The pre-setting of the spring 83 not only achieves an effective child safety, but especially in case of an extreme pre-setting of the pull spring 83, an anti-theft protection is also achieved, i.e. the handle element can no longer be easily engaged from the outside of the window, for instance by drilling through the wing frame or in another way intended for unauthorized opening of the window.
Instead of the arrester 81, the tilting lever 80 may also have a sphere. In this case, a running and guiding groove for the sphere is provided for at the circumference of the section 78, in order to achieve both a low rate of wear and tear and also a large overlay with the smallest load possible on the sphere.
Image 43 illustrates an option of positioning the tilting lever 80 by placing peg-type projections formed by permanent re-shaping of the material in the casing parts 76' around this tilting lever, which serve as support pegs for the tilting lever 81.
Images 44 and 45 illustrate a further possible design variation, a window handle 1f, which differs from the window handle 1 a in that it has a pressure spring 85, whose one end impacts upon the arrester or tilting lever 80 and whose other end is supported by an adjustable reverse support. This reverse support can be used to adjust the spring force of the pressure spring 85 from the outside. The adjustment can be done in another way, as the pressure spring 85, in its completely compressed state without another possible spring path, forms a form-locking connection between the reverse support 86 and the elverl 80 and thus completely blocks the handle element 21 in the applicable arrester position, for instance to achieve an effective anti-theft protection. In addition to the arrester lever 80, a leaf spring 87 is provided for in the building 74, whose arrester-shaped midsection also works with the lifts 79 and thus enables an arrester-controlled adjustment of the handle element 21, even when the pressure spring is completely relieved.
Further variations of the window handles 1 a and 1 f are possible. Instead of the arrester lever 80 which can be tilted on one side, a lever- or beam-type arrester piece with arrester can be provided for, whose both ends are connected to the reverse support in the casing via a spring element. In addition, a leaf spring whose spring force can be adjusted and which works with the lifts is also possible.
Images 46-49 illustrate a lock 89 with a lock latch 90 designed for a door wing 88, which can be engaged via a rotary button or knob 91 via a latch slider 92 which is activated by the knob 91. Between this latch slider 92 and a lock case plate 93, there is a pull spring 94, whose one end impacts upon the latch slider 92 and whose other end is held by an adjusting screw 95, which is positioned in the lock case plate to allow turning and which is accessible in the area of the wing groove.
Images 50 and 51 illustrate a door lock 96 which is commonly used on building doors for instance in Italy and which uses a knob 97 for opening. It has a push button 98, via which a lock latch is pressed which releases and opens the door. The push button 98 impacts upon a lever 99, which is pre-set by a pull spring from the outside of the knob 97. This forms the child safety. Image 50 shows the knob 97 with the push button 98 not pressed, and image 51 with the button 98 pressed.
In illustrations similar to images 50 and 51, images 52 and 53 show another variation, a lock 101 which differs from the lock 96 in that an additional pressure spring 102 is included as the child safety. It impacts between the push button 98 and a reverse support of the knob 97 and is adjustable from the outside in the area of the push button 98.
Image 54 illustrates a further possible variation, a door lock 24c which differs from the door lock 24b in that it has two pull springs 70' and 70" instead of the single pull spring 70. The are positioned parallel to each other and works with the eyelet lever 30c or ist extension 30c', which is equivalent to the eylet lever 30b. The two pull springs 70' and 70"
are held on one end at an adjustable reverse support or an adjusting screw 71, while their other ends reach into a separate lengthwise slit 72 in the extension 30c'.
Using two parallel springs 70' and 70" not only doubles the spring force, but each spring 70' and 70" can be individually adjusted. One of the springs, for instance the spring 70', can thus become effective immediately upon tilting of the eyelet lever 30c, while the other spring 70" only becomes effective when a certain tilting angle of this lever is reached.
The above paragraphs have described the invention in a multitude of variation examples.
It is understood that numerous further alterations and modifications are possible without abandoning the principle on which the invention is based.

It is the task of the invention to present a safety device which combines a simple design with the ability to reliably secure closing devices, for instance of window and/or door fittings or locks, against unauthorized operation.
In order to solve this task, the safety device has been designed in accordance with patent claim 1. A closing device has been designed in accordance with patent claim 26.
The safety device as per the invention can be part of the window or door fittings, e.g. at a window or door handle, and/or part of a window or door lock and/or part of a latching device or a lock for vehicle doors.
All types have one thing in common. After the safety device has been activated, operation of a door and/or window latch or a window or door lock is only possible with or after overcoming a pre-set force or a pre-set momentum (operating force). This operating force is adjustable or adjusted in such a manner that it cannot be easily opened by children or under manipulation from the outside, i.e. the safety device as per the invention on the one hand is a simply constructed but very effective child safety, on the other hand the protection against break-ins at windows, doors, etc. is significantly improved through the safety device as per the invention.
The safety device of the invention is designed in such a manner that it can be deactivated and activated, for instance by changing the operating force or characteristic force curve which is required for the operation of the applicable fitting, lock, etc.
While maintaining existing construction principles, the invention can be integrated into existing industrial fittings, handles, locks, etc. in a simple and therefore cost-effective manner. This fact as well as the simple design and operation of the safety device as per the invention thus provide the prerequisites for equipping standard fittings with a reliable safety device, especially also with a perfect child safety, without requiring extensive changes in construction and without negatively impacting upon the proven functions of standard fittings.
The invention specifically offers the opportunity to perfectly adjust the existing safety device at each door and/or each window individually in accordance with the applicable requirements and situations, for instance in regards to the age of the children. The applicable adjustment of the operating force may occur via the setting of the spring strength, via an adjustable pneumatic or hydraulic or other media, even via flexible elastic materials such as rubber or synthetic materials, polymeres, etc. The access and operating points for the adjustment of the operating force are intended to be located at easily accessible positions.
The safety device as per the invention is designed in such a manner as to require a certain operating force in accordance with an adjustable force curve for operating the applicable latching devices or the applicable lock. The adjustable force curve may be omitted and replaced by a special pre-set force or pressure point, which must be overcome in order to operate the secured latching device or the secured lock andlor to deactivate the safety device. This pressure or force point may be realized in different ways, for instance via arrester elements, springs, etc.
A further advantage lies in the fact that after activation, the child safety remains in a constantly active state, which makes manipulation by children impossible, as opposed to commonly used child safeties in car doors, which are activated or deactivated by engaging a lever, which can be accidently engaged by a child as well, at least in cases where the car is immobile and the door is open.
A further essential advantage lies in the fact that due to its simple design, the child safety can be integrated into car locks of a variety of vehicle types without requiring extensive _2_ changes in construction.
The invention also has the advantage of being of simple, constructive and thus reliable construction. The invention avoids failure-susceptible components as well as components which are easily damaged, especially in case of accidents, specifically electrical and electronic components, which makes it fully function in just about any situation.
Further developments of the invention are subject to sub-claims. In the following, the invention is illustrated using images of design examples:

The covering collar 4 is fastened in the usual fashion to the interior surface of a window wing, which is not represented here. In addition, the handle body 3 possesses at its end at section 3 a square S-shape, which extends beyond that end. This is used to connect the installed window handle 1 in the usual fashion to the closing mechanism mounted in the window wing for the purpose of operation. At its circumference, the section 3 is equipped with several groove-shaped gaps 6, specifically in the design variation illustrated, with four gaps 6, equally distributed around the axis of tha square 5. In addition, the covering collar4 contains a flexible arrester element, which in the design variation shown, is formed by a sphere 7.
This sphere 7 supports the end of a pressure spring 8, whose other end touches an adjusting element 9. The latter is formed by a nut sitting on a threaded bolt, which is positioned in a gap of the covering collar 4 to allow it to turn but not to move axially. The axis of the threaded bolt 10 is radially positioned to the axis of the square 5. The nut 9 can be moved axially, but not turned. The gaps 6, the sphere 7 and the pressure spring 8 form the child safety 11.
The pressure spring 8 flexibly presses the sphere 7 against the circumference of section 3 and arrests in pre-determined positions of the window handle 1 into one of the gaps 6, which may be equivalent to the closed or tilted positions of a window. Using four gaps 6 allows the window handle 1 to be used both on the right-hand and the left-hand side of a window or window wing. The spring 8 is, at least partially, supported by the threaded bolt 10. Through the use of suitable tools, for instance a screwdriver, it is possible to turn the threaded bolt and thus adjust the pressure generated by the spring 8 in such a manner that after the arresting of the sphere 7 into a gap 6, a turning of the window handle 1 and thus operation of the window fitting, for instance to open the window, is only possible after overcoming an operating force which cannot be accomplished by a child. Thus the settings of the tilting position of the handle element 2 as defined by the gaps 6 are secured against unauthorized operation by a child with the help of the child safety.
It is understood that the window handle 1 can also be used as a handle at a door lock, for instance at a door lock of a bulding door, for instance an interior building door. In this case, the square 5 is guided through the door in the known fashion, and a matching handle element is fastened to the end of the square 5 at the side of the door wing which is facing away from the handle element 2.
The design variation illustrated in figures 1-5 thus achieves a characteristic force line with a rising ramp through the use of the child safety, that is through the sphere 7 arresting in the gaps 6. When the sphere 7 is arrested, this force must be overcome to operate the handle element 2.
As illustrated, the force of the spring 8 and thus the characteristic force line is adjustable.
If this is not desired or required, the covering collar 4 can be of the closed variety at its circumference. In this case, the spring 8 rests on the end facing away from the sphere 7, onto a closed side of a gap intended for admitting the spring 8 and the sphere 7. In the window handle 1, the integrated child safety is thus formed by the gaps 6 and the adjustable arrest working with those gaps, and includes the sphere 7, the spring 8, the threaded part of the nut and the threaded bolt 10.
The images 6-8 illustrate a further design variation; a window handle 1 a which is different from the window handle 1 in regards to the integrated child safety 23. In the window handle 1 a, the child safety is designed in such a manner that for an access-enabling connection with the window fitting, against the effect of a spring force from an initial position, in which an access-enabling connection is not present and the child safety is activated (image 6), the handle element 2 must be pushed into a position where the child safety is then deactivated (images 7 or 8).
The window handle 1 a has a covering collar 4a, in which the handle element 2 is flexibly positioned around the axis of the square 5 in a certain angle range. For a turning/tilting window, the wing 12 and the pane 13 of which are illustrated in images 6-8, this angle range is approximately 180° between handle positions, which corresponds to the closed position, the tilted position and the position for opening the window. The square 5 working with the turning, tilting and closing fitting has a carrier 15 near the covering collar 4, which is connected to the drive of the square 5 and which reaches into a gap 16 of the handle element 2a. One end of the carrier 15 has arresters 17, for instance in the shape of a circular outside togging around the axis of the square 5, which can work together with matching arresters 18 at the bottom of the gap 16. The arresters may have an inside togging.
Between the handle element 2a and the covering collar 4a, there is a reset spring, for instance a torsion spring 19, which pre-sets the handle element 2 in a pre-determined initial position, for instance in one of the two extreme positions of the turning movement of that handle element, in which (extreme position) the handle element stops against a reverse stop of the covering collar 4a. In addition to the reverse spring 19, a pressure spring 20 operates between between the handle element and the coupling piece 15 and partially enclosing the coupling piece 15, which places the handle element 2a in a position, in which the drive connection between the handle element 2a and the coupling element 15 is interrupted and which thus matches the state "child safety activated", as illustrated in image 6. In this position, the handle element 2a can be turned against the effect of the reverse spring 19 without engaging the window fitting 14.
In order to engage the window fitting 14, the handle element 2a must be pushed against the effect of the pressure spring 20 in the direction of the window wing, as illustrated by arrow K in image 7. The operating force required for this push, through the selection of the pressure spring 20, is selected in such a manner that this force can only be applied by an adult and not a child. Image 7 illustrates the state in which the handle element 2a has been pressed against the window wing in such a manner that the carriers or arresters 17 and 18 reach into each other, thus enabling the operation of fitting 14 by tilting of the handle element, while maintaining the push onto the handle element 2a. This provides the state "child safety deactivated".
The window handle 1a also provides for the option of fixing the state "window handle deactivated", as illustrated in image 8. The handle element 2a, i.e. in the case of the design variation illustrated, at the edge of the opening of gap 16, has a circular arrester 21, which reaches into a circular reverse arrester 22 on the coupling element 15, if the handle element 2a is pushed beyond the state illustrated in image 7 in the direction of the arrow K into the opening of the covering collar 4a, i.e. in the direction of the wing frame.
By pulling in the direction of the arrow K, using a pre-set force which can be adjusted by selecting spring arrester 21 or 22, the handle element can be re-positioned from the state of image 8 to the state of image 6.
The integrated child safety 23 for the window handle 1a is therefore mainly formed by the coupling element 15 with the coupling section 17 and the handle element 2a with the coupling section 18, which can be moved relatively to the coupling element 15 in the direction of the axis of the square 5 and against the effect of the pressure spring 20.
Image 9 illustrates the use of the handle 1 a as a door handle at a door 12'.
For this use, the square 5 is guided through the door 12' and the door lock in the known fashion, so that a further handle element 2a can be fastened to the square 5 on the side of the door 12' which faces away from the handle element 2a'.
The variation illustrated in image 9 provides for a child safety 23 at one side of the building door 12' only. The functionality of the child safety 23 is identical to the function as described above in connection with images 6-8.
The variations illustrated in image 10 provides for a handle 1 a with matching child safety for each side of the building door 12'.
_g_ Similar to image 6, image 11 illustrates a handle 1 b which is different from handle 1 a in that it has a pressure spring 20b instead of the pressure spring 20, whose spring force is adjustable. This is done via a threaded rod 20b which is guided in a threaded nut piece, for instance in a nut 20b" in the handle element 20 b. The threaded rod 20b' provides the support to one of end of the spring 20b, whose other end is supported by the coupling piece 15. The threaded bolt 20b' is accessible for adjusting the force of spring 20b at the side of the handle element 2b facing away from the square 5, and should be covered by a suitable cover.
Images 12-16 illustrate a door lock 24, whose lock case 25 containing the functional elements of the door lock 24 can be fastened in a lock case opening at the groove side of the door in the usual fashion, so that the plate 26 is located in the groove of the door wing and that the lock is secured in the lock case opening of the door via this plate and through the use of screws. In the design variation illustrated, the lock 24 has a key-bolt 27 operated by a key as well as a flexible lock latch 28, which can be moved from the closed position, in which the lock latch 28 extends out of the lock case and beyond the plate 26, to an opening position via an eyelet 29 flexibly positioned in the lock case 25 and a lever 30 radially positioned at this eyelet. The eyelet is equipped with a square opening 31 in the known fashion, into which the square not illustrated of the door handles also not illustrated reaches.
The lock 24 is equipped with an adjustable child safety. This is generally identified as 32 and consists of a double-armed turning lever 33, which can be moved around an axis parallel to the axis of the eyelet 29. One end of the turning lever 33 has a pressure lever 34, whose other end is freely supported by a support point formed at the transition between the eyelet 29 and the lever 30. The other end of the lever 33 has a support element 35, which mainly consists of a plate and a peg positioned at the free side of this plate. This support element 35 supports one end of a pressure spring 36, whose length extension is basically radial to the length extension of the lever 33, in a mutual plane with the length extension of this lever, said plane being vertical to the plane of the axis of the eyelet 29. The other end of the pressure spring 36~is supported in the area of the lock plate 26 by an adjustable support, specifically a threaded nut piece 38 of this support. The threaded nut piece 38, which in the design variation illustrated is formed by a hexagon nut, rests on a threaded bolt 39, whose positioning at the lock plate 26 allows turning but no axial movement, and which is accessible at the outside of the lock plate through the use of a suitable tool such as a screwdriver, so that by turning the threaded bolt 39 and the resulting movement of the threaded nut piece 38 along the threaded bolt 39, the pre-set force of the pressure spring 36 can be set. Since the threaded nut piece 38 is supported by the end of the pressure spring 36, the threaded nut piece 38 is held into place by this pressure spring without any danger of turning. In addition, the design ensures that when turning the eyelet 29 into the open position as part of the movement of the lock latch 28, the lever 33 is turned via the pressure lever 34 in such a manner as to allow an additional setting of the pressure spring 36.
In images 13 and 14, the pre-set force of the pressure spring 36 is set in such a manner that a relatively easy turning of the eyelet 29 and thus a relatively easy moving of the lock latch 28 from the closed position (image 13) to the open position (image 14) is possible. The threaded nut piece 38 is located near the lock plate 26.
Images 15 and 16 illustrate the state in which the pressure spring 36 is pre-set to the extent that moving the eyelet 29 via the applicable door handle and thus moving the lock latch 28 from the closed position (image 15) to the open position (image 16) is only possible after overcoming a relatively large operating force or a relatively large momentum, which ensures that the door cannot be opened by a child. This means that images 13 and 14 illustrate the state "child safety deactivated", while images 15 and 16 illustrate the state "child safety activated". The threaded nut piece as shown in images 15 and 16 displays a considerable circumstance from the lock plate 26.
In the lock 24 the child safety 32 installed in the lock case 25 is mainly formed by the levers 33, 34 and the adjustable pressure spring 36, the latter being located in the lock case above the latch 28. 14 refers to a leaf spring, which among other things is used to pre-set the lock latch 28 into the closed position in lock 24.
Images 17-20 illustrate another possible design variation, a lock 24a whose only differences to lock 24 are the fact that the pressure spring 36 is located in the lock case 25 between the eyelet 29 and the key-bolt 27 and that the lever-33-equivalent lever 33a works on one end with a stop 42 via a spring 41 in the area of operation 33a', which is provided for on the lock latch 28 or its latch slider 28' and onto which the lever 30 of the eyelet 29 also impacts. The other end of the lever 33 touches the end of the pressure spring 36, whose other end is supported by the adjustable support 37. The pressure spring 41 serves as reset spring for the latch 28. When tilting the eye 29 over the door handle not illustrated, the latch 28 is moved back from the closed position to the open position via the lever 36 touching the stop 42 by tighening the pressure spring 41 or 36.
The pressure spring 36 is significantly harder than the pressure spring 41.
The pressure spring 36 can be pre-set in different ways due to the adjustable support 37.
Images 17 and 18 illustrate the state "child safety deactivated". The pressure spring 36 is not or only slightly pre-set. The threaded nut piece 38 is this in the vicinity of the lock plate 26. When engaging the eyelet 29, the lock latch 28 is moved from the closed position (image 17) to the open position (image 18), simply by reshaping the pressure spring 41.
Images 19 and 20 illustrate the state °child safety activated", in which the pressure spring 36 is suitably pre-set and the threaded nut piece is thus located at a distance from the inside surface of the Jock plate 26. Since the pressure spring 36 is significantly harder than the pressure spring 41, the latter is pushed together so far that the lever 33a with its hook-shaped angular end 33a' directly touches against the stop 42, even when the latch 28 is in the closed position. The tilting of the eyelet 29 and thus the moving of the latch 28 from the closed position (image 19) to the open position (image 20) is therefore only possible upon overcoming a relatively high turning momentum generated by the force of the pressure spring 36. The selection of the pressure spring 36 and/or the setting of the pressure spring are such that this cannot normally be done by a child. In the door lock 24a, the adjustable support 37 or its threaded bolt, which is used for the pre-setting of the pressure spring 36, can be accessed from the outside of the lock plate 26.
Images 21-24 illustrate a very simplified view of a car door lock 44 with a tiltable key-bolt 46 provided for at the lock case 45 of the door , which works with an applicable counterpart at a fitting of the vehicle so that the tilting positon of the key-bolt 46 illustrated in images 21 and 23 reflects the closed car door and the tilting position of the key-bolt 46 illustrated in images 22 and 24 allows the car door to be opened. The tilting of the key-bolt 46 occurs via a hinged axis 47 which is located in the lock case 45.
Via a pressure spring 48, which works between one end of a key-bolt lever 46' radially positioned from lever 46 and a plate 49 of the lock case 45, the key-bolt 45 is pre-set in the closing position. The pressure spring 48 is supported by the plate 49 via an adjustable support 50, which is equivalent to the design of the adjustable support 37 and on which the pre-setting of the pressure spring 48 can be performed from the accessible side, for instance from the outside when the vehicle door is open.
On the inside of the vehicle door, a lever 52 is flexibly positioned in a casing 51, which is connected to a key-bolt 46 via a rod structure 53. Thus when the lever 52 is tilted from its initial position, in which the lever 52 is located in the casing 51 (images 21 and 23), and into a position where the lever 52 extends beyond the casing 51 (images 22 and 24), the key-bolt 46 is moved from the closed to the open position.
Images 21 and 22 illustrate the state "child safety deactivated" in which the pressure spring 48 is only slightly pre-set and thus a tilting of the key-bolt 46 from the closed position (image 21 ) into the open position (image 22) is possible with only a small amount of force.
Images 23 and 24 illustrate the state "child safety activated" in which the pressure spring 48 is suitably pre-set so that only when a force is applied which cannot normally be applied by a child, the key-bolt 46 is moved from the locking position (image 23) to the open position (image 24) by tilting the lever 52.
Images 25-28 illustrate a further possible design variation, a door lock 44a, which is different from the door lock 44 in that the pressure spring 48a, whose function is equivalent to that of the pressure spring 48, works between the casing 51 and the lever 52 and is provided for at the reverse of the casing 51. The pressure spring 48a is supported between a projection 52a of the lever 52 connected to the rod structure 53 and an adjustable support 50a, which is provided for in the area of the trough-shaped depression of the casing 51 and which is accessible via this depression.
Images 26 and 26 illustrate the state "child safety deactivated", in which the pressure spring 48a displays only a slight pre-setting. Images 27 and 28 illustrate the state "child safety activated where the pressure spring 48a is more strongly pre-set.
The car door locks 44 and 44a with child safety as illustrated in images 21-28, compared to commonly used child safety devices, have the advantage of allowing the applicable car door to be opened by an adult at any time, especially in case of an accident, thus enabling speedy rescue.
The previous paragraphs were based upon the assumption that the force of the springs 48 and 48a is manually adjustable with the help of the setting elements 50 or the setting screw.
However, there is another general option to perform the setting of the spring force mechanically via actuators, which may be operated via an operating element which is accessible in the area of the driver's seat, for instance an operating element included in the dashboard. Like the other variations, the following also applies to this variation: even when the child safety has been set to the strongest setting, i.e. the applicable spring element is set to the strongest spring force, this force cannot be applied by a child, but can be easily overcome by an adult in case of emergency so that in case of an accident, the door can be opened by an adult. This also means that the possibility of opening the car door by an adult with the child safety activated does not depend on the faultless functioning of any electronics.
Actuators for the mechanical setting of the spring force are for instance electrical or electromagnetic actuators such as actuators or motors based upon magnetic force. Other actuators such as hydraulic actuators are also possible. The applicable actuator is integrated for instance in the lock area or in the area of the door handle.
Unlike the special design variations illustrated in the images, the spring-type elements can naturally be provided for at another suitable location as well, for instance in the area of the rod structure between the door handle and lock. Instead of the springs 48 and 48a, other elements acting as springs may also be used, for instance those made of plastic and/or metal.
Images 29 and 30 illustrate another possible design variation, a window handle 1c, which is similar to the window handle 1 and whose covering collar 4c has two spring elements 60, whose spring force is adjustable and who work with groove-type gaps 6 at the section 3 of the handle element 2c. The spring elements 60, which are positioned radially to the axis of the section 3c or the square 5 of the handle element 2c and facing each other diametrally, consist of sliding piece 61, which can be moved in a guiding rail of the covering collar 4c in the axis direction A and which has a sphere 62 on the side facing the section 3c which works with the gaps 6. Supported by this sliding piece 61 is a pressure spring 63, whose radial outside end touches a reverse stop 64, which can be adjusted with a screwdriver via a screw-bolt 65. Through the use of the four gaps 6, the window handle 1 c has a total of four arrester positions, three of which are used by a window with a turning/tilting fitting when installed (either left or right installation). If the force of the springs 63 is set accordingly, the child safety at every arrester position is achieved in such a manner that the window handle 1 c or its handle element 2c cannot be operated by a child, since only an adult is able to apply the force required for overcoming the arrester generated by the springs 60.
Images 31 and 23 illustrate in a view like image 29 and 30 a door handle 1d, which is different from the window handle 1 c in that the handle element 2c does not have the groove-type gaps 6 in its section 3d which reaches into the opening of the covering collar 4d.
Instead it has two wing-type projections 66 forming two lifts or ramps, which work with the spheres or the flexible sliding pieces in such a manner that the door handle can only be opened if the flexible sliding pieces are simultaneously moved radially to the outside against the force of the pressure springs through the ramps or projections 66. In this case the two pressure springs can also be adjusted so that the force for opening of the door can only be applied by an adult but never by a child. The ramps formed by the projections 66 can be shaped in such a manner that a continuous force increase, depending on the tilting angle of the handle element 2d is achieved, which results in an especially comfortable operation.
Unlike the design variations described, the child safety can also be achieved by providing for a push button on the handle element, which when engaged will release a child-safety blocking and enable the applicable handle element to be tilted. In this case the push button is also pre-set via ad adjustable spring force so that this spring force cannot be overcome by a child but only by an adult.
Images 33-39 illustrate another possible design variation of the door handle 24b, which differs from door handles 24 and 24a in that a pull spring 70 is provided for in the lock case 25 for the child safety. One of its ends is held by an adjustable support 71, accessible via the lock case plate 26, and its other end impacts upon the extension 30b' of the eyelet lever 30b, whose function is equivalent to that of the eyelet lever 30, i.e. which serves for engaging the lock latch 28b or the lock latch slider 28b against the effect of the leaf spring 40.
In the extension 30b' there is a lengthwise slit 72, which is at a tangent or an approximate tangent to the supposed circle around the axis of the square 31 and into which the other end of the pull spring 70 is hooked. Depending on the setting of the adjustable support 71, which can simply be formed by a screw, on whose threading one end of the pull spring 70 or a threaded nut piece connected to the pull spring is held, the effect of the child safety formed by this pull spring is adjustable, i.e. the force required for opening the lock latch is adjustable between the value Zero and a maximum value.
Images 34-36 illustrate the state in which the pull spring 70 is without effect or the child safety is turned off. Images 34 and 35 show this with the lock latch 28b extending beyond the lock case plate 26, and image 36 with the door handle pushed and the latch 28b moved back into the lock case 25. Images 37 and 38 illustrate the setting of the pull spring 70, for which (setting) the pull spring is guaranteed to be effective if the door handle is completely pressed down or if the lock latch 28b is completely pulled in. Image 38 illustrates a setting in which the pull spring 70 is already effective during the quiescent state of the lock, i.e. when the latch 28b is extending beyond the lock case plate 26.
Image 40 shows different views or positions a - h of the lock latch 28b and the matching latch slider 28b'. As illustrated, the actual latch 28b is removably fastened to the latch slider 28b' by a screw 73, which is accessible via the free end of the lock latch 28b and thus from the outside of the lock case plate 26. In addition, the latch slider 28b' and the lock latch 28b are designed in such a manner that the latch 28b can be fastened to the front side of the latch slider 28b in two positions which are turned at an 180° angle from the length of the slider 28b. Thus the door lock 24b can be used for left- or right-controlled doors. Both fastening options of the lock latch 28b to the latch slider 28b', in addition to the connection via the screw 73, achieve a form-locking connection between those elements.
The door lock 24b, when compared to the door lock 24, has the advantage that the spring force required for the child safety is not effected by an additional lever, but that the eyelet lever 30b is used for this in the manner described above. No basic changes are necessary for the integration of the child safety into the door lock 24b, compared to the commonly used design, which means that the child safety can be integrated easily into existing, proven constructions. In addition, the positioning of the pull spring 70 is extremely favourable from a mechanical point of view so that the pull spring 70 is easy to operate.
The connection of the pull spring 70 with the adjustable support 71 or with screw forming this support is realized for instance by the pull spring 70 reaching into the screw thread or by providing for a threaded sleeve or a threaded nut piece at the applicable end of the pull spring, which works with the screws.
The length of the lengthwise slit 72 is equivalent to the path or angle length, by which the eyelet lever 30b is moved when the door handle is completely pressed down or when the door handle is completely tilted.
A further, especially favourable characteristic of the door lock 4b is the fact that the leaf spring 40 is fully effective even when the child safety is turned off. Thus the standard function of the door lock remains unchanged, while the applicable setting of the adjustable support 71 results in the gradually adjustable effect of the pull spring 70.
By using the pull spring 70, the adjustable support 71 can also be easily formed by a screw, whose screw head (flat head) is held in a matching drill hole of the lock case plate 26.
As illustrated by images 37 and 38, the setting of the pull spring 70 may be executed in such a manner that at the beginning of the opening movement via the eyelet lever 30b, only the leaf spring 40 is effective, and only when the lock latch 28b is moved further back, the effect of the pull spring 70 is added.
A special advantage of the door lock 24b is the fact that the spring force of the lock latch 28b does not depend on the setting of the pull spring 70 and is determined by the leaf spring only.
When installing the applicable door into a building, major tolerance may occur so that when the door is closed, the lock latch 28b no longer reaches into the applicable opening of the lock plate with its entire length, but only with a portion of its length. In this case, a reliable child safety can still be achieved by the applicable setting of the pull spring 70.
Since th pull spring 70 directly impacts upon the eyelet lever 30b and no additional lever structures are required, the result is not a simplified construction but also a design with very little wear and tear.
The opening for the lock latch 28b in the lock latch plate is designed in such a manner that by turning the lock latch 28b a usage in either a left or right door wing is possible, while a reliable guidance of the lock latch 28b at the lock case plate 26 is still guaranteed. The positioning of the lock latch 28b, but also of the key-bolt 27 in the design variation shown are in the middle of the lock case plate 26.
Images 41 and 42 illustrate a simplified and reverse view of a window handle with a handle element 2a, which can be tilted on a casing 74 and has again the square 5. The casing 74 has two sides and consists of an outer casing part 75 and an inner casing part 76. The latter can be made of plastic or metal and has two drill holes 77 for the fastening of the window handle 1 a to a window wing. The outer casing part 75 which covers the inner casing part 76 like a dome, is also made of a suitable material, for instance metal or plastic. Both casing parts have a drill hole, in which the section 78 of the handle element 2e, which takes in the square 5, is positioned so that it can be turned. The circumference of the section 78 has arrester lifts 79, in the case of the design variation illustrated four such lifts, which work with an arrester 81 formed at a tilting lever 80. The arrester 81 is located on one side between the two ends of the tilting or arrester lever 80, whose one end can be tilted via a joint 82 at the inner casing part 76 within the building around an axis parallel to the tilting axis of the handle element 2e. Its other end works with one end of the spring 83, which is held by a screw 84 on the inner casing 76 so that the screw is accessible from the outside for setting of the spring force of the pull spring 83. Via the setting of the pull spring 83, the force required for the renewed tilting of the handle element 2a after the engaging of the arrester 91 in a groove 79 can be adjusted.
The handle element 2e can be connected to the casing 74 in different ways. The pre-setting of the spring 83 not only achieves an effective child safety, but especially in case of an extreme pre-setting of the pull spring 83, an anti-theft protection is also achieved, i.e. the handle element can no longer be easily engaged from the outside of the window, for instance by drilling through the wing frame or in another way intended for unauthorized opening of the window.
Instead of the arrester 81, the tilting lever 80 may also have a sphere. In this case, a running and guiding groove for the sphere is provided for at the circumference of the section 78, in order to achieve both a low rate of wear and tear and also a large overlay with the smallest load possible on the sphere.
Image 43 illustrates an option of positioning the tilting lever 80 by placing peg-type projections formed by permanent re-shaping of the material in the casing parts 76' around this tilting lever, which serve as support pegs for the tilting lever 81.
Images 44 and 45 illustrate a further possible design variation, a window handle 1f, which differs from the window handle 1 a in that it has a pressure spring 85, whose one end impacts upon the arrester or tilting lever 80 and whose other end is supported by an adjustable reverse support. This reverse support can be used to adjust the spring force of the pressure spring 85 from the outside. The adjustment can be done in another way, as the pressure spring 85, in its completely compressed state without another possible spring path, forms a form-locking connection between the reverse support 86 and the elverl 80 and thus completely blocks the handle element 21 in the applicable arrester position, for instance to achieve an effective anti-theft protection. In addition to the arrester lever 80, a leaf spring 87 is provided for in the building 74, whose arrester-shaped midsection also works with the lifts 79 and thus enables an arrester-controlled adjustment of the handle element 21, even when the pressure spring is completely relieved.
Further variations of the window handles 1 a and 1 f are possible. Instead of the arrester lever 80 which can be tilted on one side, a lever- or beam-type arrester piece with arrester can be provided for, whose both ends are connected to the reverse support in the casing via a spring element. In addition, a leaf spring whose spring force can be adjusted and which works with the lifts is also possible.
Images 46-49 illustrate a lock 89 with a lock latch 90 designed for a door wing 88, which can be engaged via a rotary button or knob 91 via a latch slider 92 which is activated by the knob 91. Between this latch slider 92 and a lock case plate 93, there is a pull spring 94, whose one end impacts upon the latch slider 92 and whose other end is held by an adjusting screw 95, which is positioned in the lock case plate to allow turning and which is accessible in the area of the wing groove.
Images 50 and 51 illustrate a door lock 96 which is commonly used on building doors for instance in Italy and which uses a knob 97 for opening. It has a push button 98, via which a lock latch is pressed which releases and opens the door. The push button 98 impacts upon a lever 99, which is pre-set by a pull spring from the outside of the knob 97. This forms the child safety. Image 50 shows the knob 97 with the push button 98 not pressed, and image 51 with the button 98 pressed.
In illustrations similar to images 50 and 51, images 52 and 53 show another variation, a lock 101 which differs from the lock 96 in that an additional pressure spring 102 is included as the child safety. It impacts between the push button 98 and a reverse support of the knob 97 and is adjustable from the outside in the area of the push button 98.
Image 54 illustrates a further possible variation, a door lock 24c which differs from the door lock 24b in that it has two pull springs 70' and 70" instead of the single pull spring 70. The are positioned parallel to each other and works with the eyelet lever 30c or ist extension 30c', which is equivalent to the eylet lever 30b. The two pull springs 70' and 70"
are held on one end at an adjustable reverse support or an adjusting screw 71, while their other ends reach into a separate lengthwise slit 72 in the extension 30c'.
Using two parallel springs 70' and 70" not only doubles the spring force, but each spring 70' and 70" can be individually adjusted. One of the springs, for instance the spring 70', can thus become effective immediately upon tilting of the eyelet lever 30c, while the other spring 70" only becomes effective when a certain tilting angle of this lever is reached.
The above paragraphs have described the invention in a multitude of variation examples.
It is understood that numerous further alterations and modifications are possible without abandoning the principle on which the invention is based.
