Description

Handle with associated locking mechanism

The invention relates to a handle with an associated locking mechanism, in particular for doors, windows, drawers or jugs.

The area of application includes room doors, toilet doors, cupboard doors and, in the area of jugs, thermos flasks, coffee pots and teapots. The other area of application includes bags. In general, the handle of the type mentioned above can be used wherever an object needs to be opened or unlocked, closed or locked.

Until now, the state of the art has been to use special locking mechanisms for each application, with the locking and unlocking mechanism also being completely developed for the respective application. The locking mechanism was not universally applicable and was usually technically complicated.

The object of the present invention is to create a simple, reliable locking mechanism that can be used in a variety of ways with minor modifications.

This object is achieved according to the invention for a handle with an associated locking mechanism in that a pressure mechanism of a push-button ballpoint pen is arranged within the handle, which is shaped as a hollow body, which can be triggered by actuating a push-button and is connected to a latch in such a way that it can be locked and unlocked with the pressure mechanism.

According to the invention, a simple handle with an integrated locking mechanism is created, which not only enables

It is possible not only to grasp and move the object to be opened and closed, for example a door, but also to carry out the unlocking or locking process, which would otherwise be carried out by swiveling the handle or a separate mechanism. The handling of opening and closing an object is thus simplified. Depending on the design of the door handle with pusher, variants of which are shown below in a further development of the invention, it may not even be necessary to use your hands to open the door; this can also be done using your elbow, for example. This is advantageous in public toilets for hygienic reasons.

It is also possible to use a conventional, pivoting door handle to implement the invention, provided that it is hollow and can accommodate the pressure mechanism of a ballpoint pen inside. The pressure mechanism and the elements connected to it can then be used for additional locking and unlocking.

Furthermore, the fixed installation of the handle according to the invention, which allows locking or unlocking only with the push button, is particularly useful in old people's homes, nursing homes and homes for the disabled because of its particularly easy handling, since it is very easy to operate and does not require a great deal of force or great skill.

In an advantageous embodiment of the handle with associated locking mechanism, the handle protrudes from one end of the handle and is mounted in the handle so that it can be moved in its longitudinal direction. The handle is connected to elements of the pressure mechanism that can be moved in the handle in the longitudinal direction, which is also connected to the latch. With this simple and space-saving arrangement, the handle remains smooth and easy to handle. Nevertheless, the protruding from the end of the handle remains

Handles are easily accessible during handling to lock or unlock.

To guide the longitudinally movable elements of the pressure mechanism, guide rails running in the handle’s longitudinal direction are provided. They are formed on the inside of a cylindrical wall of the handle, which is shaped as a hollow body.

in detail, the displaceable elements of the pressure mechanism are designed according to the characterizing part of claim 4, with the first toothed cylindrical part and the second toothed cylindrical part, both of which are displaceable in the longitudinal direction in the hollow body of the handle, being the essential elements. However, the first cylindrical part can have a different even number of η teeth instead of eight teeth, where η is an even number greater than or equal to 4. This includes an equal number of guide rails in the handle according to claim 3. The number of rungs on the second toothed cylindrical part is generally n/2.

These two toothed cylindrical parts together form the pressure mechanism, which is completed by a compression spring with which the first toothed cylindrical part and the second toothed cylindrical part are pressed together. The first toothed cylindrical part and the second toothed cylindrical part can then be moved from their initial position for locking against the force of this compression spring by operating the pusher. When the pusher is released, the first toothed cylindrical part and the second toothed cylindrical part remain in their pressed-down position. This position is only left when the pusher is operated again, whereby the interlocking parts, namely the first toothed cylindrical part and the second toothed cylindrical part, slide upwards in grooves or guide rails in the hollow body of the handle and the pusher moves out of the handle by the length of the groove.

especially the front side pushes out.

The movement of this toothed construction can be transmitted, for example according to claim 5, by a deflection wheel on the side of the pressure mechanism opposite the pusher and a cable which is guided essentially transversely to the longitudinal direction of the handle, from a rod attached to the second cylindrical part and a second rod which is hinged on the one hand to the first rod and on the other hand to the deflection roller.

The deflection wheel and the cable redirect the force from the pressure mechanism via an intermediate part of the handle, which serves to hold the actual handle at a distance from the door leaf or the like. Inside the door leaf, the force that is emitted by the locking mechanism in the handle is again redirected so that it pushes the horizontally arranged sliding bolt out of the door leaf.

The compression spring, which presses the first toothed cylindrical part and the second toothed cylindrical part of the pressure mechanism together, can, in an embodiment according to claim 6, be supported on the one hand on a cap-shaped receptacle, which forms the pressure transmission element on the second toothed cylindrical part, and on the other hand on a fixed stop in the handle in order to push the first toothed cylindrical part and the second toothed cylindrical part onto one another.

In a second embodiment, however, the spring is not inside the handle, but visibly outside the handle, where it is supported between a head end of the handle and a pusher protruding from it. A section of the pusher passes through the spring, which holds the spring securely.

Depending on the requirements, the head of the pusher can be curved outwards or inwards, i.e. concavely curved. The variants are specified in claims 8 and 9.

The pusher can also be split in two and have a neck with a head end attached to it, as stated in claim 10. The neck has the same function as the original pusher. This enables a variety of shapes of the head end to be created in a rational manner, independent of the function of the neck of the pusher.

For this two-part design, the neck of the handle conveniently contains a screw or plug-in mechanism to which a separate head end can be attached. The head end is therefore replaceable.

The head end of the pusher can be curved in a teaspoon-shaped manner, in particular according to claim 12, in order to form a large actuating surface.
20

The handle, into which the pressure mechanism of a push-button ballpoint pen is integrated, can be cylindrical on the outside according to claim 13.

In a further development, however, the handle can also be designed as a double cone according to claim 14, with each conical handle section tapering from a common central plane. In a special embodiment according to claim 15, the handle has a cushion-shaped hollow head with a pusher inserted into it transversely to the main longitudinal direction of the handle. The pusher is connected to the first toothed cylindrical part of the pressure mechanism via gears and a cable in the head.

In an application for closing a jug, according to claim 16, the pusher in a jug handle is provided with a pressure mechanism that is in a force-locking connection with it.

mus of a push-button ballpoint pen, which is connected to a plug/latch that can be swivelled into the can opening.

In a variant of the above application, the pusher and the pressure mechanism of a pressure ballpoint pen that is in a force-locking connection with it can also be accommodated in the can wall according to claim 22.

The jug lid, which can be pivoted about a joint, has a recess that accommodates the push button so that the jug lid does not hinder the function of the handle with the locking mechanism and the push button.

In order to ensure that the push button can be operated safely even by inattentive persons, the push button is suitably arranged in the handle in accordance with claim 19 in such a way that the handle can only be grasped together with the push button.

The handle mentioned at the beginning, in which the locking mechanism is integrated, can be a hollow door handle according to claim 20. If this can be pivoted in the usual way and is connected to a spring-loaded latch, the normal function of the door handle is retained. The locking mechanism integrated in the handle with associated elements can then additionally unlock or lock the door when the handle is operated. Operation is possible in two places, namely left- or right-handed. 30

In a modified application according to claim 21 for a swing door, the bolt is designed as a roller that can be moved relative to an essentially star-shaped wheel by the pressure mechanism. The star-shaped wheel has recesses adapted to the shape of the roller and thus practically forms a negative form with several contact points for the roller. The star-shaped wheel is mounted in a door frame.

1, in which the spring is located that presses the star-shaped wheel towards the roller. When the roller is moved by the pressure mechanism to its outermost position facing the star-shaped wheel, the door is locked. When the pressure mechanism is actuated again, it unlocks the roller, which can then move back when it is swung over the star-shaped wheel until the star-shaped wheel releasably engages in the roller.

In Fig. 1-3, 1' generally designates a handle, more precisely its main part, which is shaped as a hollow cylinder, from which eight guide rails or track grooves 1 are formed at an even circumferential distance - see Fig. 2 -, the guide rails running in the main axial direction of the handle 1'. A pusher 2' is slidably mounted in one end face of the handle 1', which merges into a first toothed cylindrical part 2, which has eight teeth running longitudinally on its casing, see Fig. 4. The teeth taper to a point on their end faces and protrude below the casing. The lower section of the first toothed cylindrical part 2 is

9..

toothed cylindrical part 2 is formed as a hollow cylinder, into which a second toothed cylindrical part 3 fits slidably and rotatably.

The second toothed cylindrical part 3 has 4 longitudinal rungs on its circumference, which are placed on the outside of the part. The rungs are shaped as spikes at their upper end. At the bottom, the rungs are connected to a cap-shaped holder 3' with a compression spring 6, which is supported on an unmarked fixed stop inside the handle 1'.

The second toothed cylindrical part 3 is connected to a deflection wheel 7 in a force-transmitting manner via a first rod 4 attached to it at the bottom, which is articulated to a second rod 5, one end of the second rod 5 being articulated to the deflection wheel 7. From the deflection wheel 7, a cable 8 leads transversely to the longitudinal direction of the handle 1' via an intermediate section 9 of the handle to a door leaf 12, in which it is connected to a latch 11, see Fig. 1 and 3.

The power transmission with the deflection wheel 7 and the cable pull 8 has the advantage that the handle can be adjusted in height and, if necessary, arranged in conjunction with a guide rail on the door leaf.

The track grooves or guide rails 1 are designed as a mirror image of the rungs of the second toothed cylindrical part 3 and are in engagement with it. When the first toothed cylindrical part 2 of the second toothed cylindrical part 3 is pressed down against the force of the compression spring 6 by actuating the pusher 2', the rod 4 is also pressed down, which actuates the latch 11 via the intermediate elements. As a result of the design of the pressure mechanism with the first toothed cylindrical part 2 and the second toothed cylindrical part 3 in conjunction with

■ »· «

The guide grooves in the handle ensure that when the pusher 2' is pressed down for the first time, the latch remains locked in the position pressed out of the door leaf 12. By operating the pusher 2' again, the interlocking elements of the pressure mechanism slide upwards along the track grooves 1, the pusher 2' moves by the length of the groove and the latch is retracted into the unlocked position, see Fig. 1.

Together with the latch, a color signal field (not shown), e.g. with a red and green field, can also advantageously be moved behind a window in the door leaf in order to indicate the locking state of a toilet door in particular. Alternatively, a movable color signal field can also be arranged in the handle 1' and connected there to the rod 4.

Further variants of the pusher are evident from Fig. 1 and 3: In Fig. 1, the head of the pusher 2' is curved outwards. According to Fig. 3, however, the head of the pusher 2'' is curved inwards, ie concavely curved.

In the embodiment of the handle according to Fig. 6, the compression spring 6' is located outside the handle between its head end 1'' and an unmarked collar of a pusher 2'' protruding from the head end ^1r ' , whereby the latter extends through the spring 6'. The spring 6' is thus supported between the head end 1'' and the collar of the pusher 2'' .

From the embodiment according to Figs. 7 and 8 it can be seen that the pusher, which is designed with a neck 13 and a head end 12, protrudes from the handle (not shown). The neck 13 has the same function as described above in connection with the actual pusher. The head end formed onto the neck is large and ergonomically curved in the shape of a teaspoon. - To clarify the installation position of the handle, an intermediate element of the handle is shown in Figs. 7 and 9, which

which connects the actual handle with the door leaf, marked 9'.

In Fig. 9, the variant of the handle according to Fig. 7 and 8 is shown in a side view rotated by 90° compared to Fig. 8, from which further shape features of the head end 12 emerge. In particular, it can be seen that the head end 12 is inclined relative to the neck 13. The actual handle is cylindrical on the outside, like the handles described above.

In contrast, in the embodiments of the handle according to Figs. 10, 11 and 12, this is essentially designed as a double cone, with each conical handle section 14, 15 tapering outwards from a common central plane, which is indicated in Figs. 10 and 11 with the dash-dotted line 15'. In the double cone shape, the door handle is ergonomic and particularly attractive.

In Fig. 12, such a handle is shown in a horizontal installation position on an unmarked door leaf. In this figure it is also indicated how a latch 11' is connected to the inside of the handle, for example via a cable pull, see dotted line 8'. The handle can be grasped with the right hand, while the handle 2' is operated with the right thumb.

In the embodiment shown in Fig. 13, the handle has a cushion-shaped hollow head 16, in which a pusher 17 is slidably inserted across the longitudinal direction. The interior of the hollow pusher and the hollow head accommodate the undesignated pressure mechanism with the compression spring 6''. The compression spring 6'' presses the pusher 17 outwards. When the pusher 17 is pressed down, it acts via a rod 5' on a gear 19, which meshes with a gear 19' in order to move a first toothed cylindrical part 18 via a cable 8 or another movable connecting piece.

of a pressure mechanism. The first toothed cylindrical part 18' with eight teeth in this example interacts in turn with the second toothed cylindrical part 3, which has four rungs on the outside. The movement of the second toothed cylindrical part is transmitted to a latch 11" via a further movable connecting element 8', which is attached to the second toothed cylindrical part 3.

In Fig. 14, a vertical handle 20' of a teapot is shown, which tightly closes an unmarked mouth of a pot spout with a stopper/latch 22. For this purpose, a push button or push-button 20 is arranged in the hollow handle 20' at its upper end so that it can be moved vertically, which projects into a recess in a pot lid 20'' that can be pivoted about a joint 21. The push button 20 is followed at the bottom by an unmarked first toothed cylindrical part and a second toothed cylindrical part, also unmarked, which are pressed against one another by a compression spring 6. A rod element 5'' connected to the second toothed cylindrical part represents a connection to gears 19, 19' of a gear system which redirects the force from the rod element 5" to the closure 22. By successively operating the pusher 20, the mouth in the jug outlet can thus be sealed or opened.

The addition to the bolt shown in Fig. 15, which is designed here as a roller 23 and can be actuated by a pressure mechanism (not shown) in a door handle, as basically described in connection with Figs. 1-5, works together with a star-shaped wheel 24, which is arranged in a door frame. The star-shaped wheel 24 has recesses adapted to the outer shape of the roller. It is pressed towards the roller 23 by a spring 25. This arrangement is particularly suitable for a swing door, since the roller 23, which can snap into one of the recesses mentioned in the star-shaped wheel, keeps the door in its desired position.

positioned. By operating the handle (not shown), the roller 23 is pressed so firmly onto the star-shaped wheel 24 that the door is locked. By operating the handle (not shown) again, it is unlocked again.

In Fig. 15a, the door handle 32 belonging to Fig. 15 is shown with a spherical pusher 31 on its front side.

In the embodiments shown in Fig. 16, 17 and 18, the handle (not shown) has a push button 26, 27; 28, 29; 30, 31 at two points spaced apart from each other. The direction in which the push button is operated is indicated by an arrow. This double arrangement of the push button makes operation significantly easier.

In Fig. 19, in a modification to the teapot in Fig. 14, it is shown how a pressure mechanism 32 of a pressure ballpoint pen can be accommodated in a pot wall formed with a receptacle 33. The pressure mechanism 32 is connected to a stopper 38 in the pot spout 39 via a rod 34, gears 35, 36 and a cable 37. The pressure mechanism 32 and thus the stopper 38 are again conveniently operated via a push button 40, which is arranged so close to a pot handle 41 that it can be operated with the same hand at the same time as the pot is gripped by the handle 41.
