[0028] In the following description of the figures, identical elements or functions are provided with identical reference signs.

[0029] A handle assembly 1 for operating a door, for example, is well known. The handle assembly 1 consists of two handles 10, 11 arranged on each side of a door, more precisely a door leaf, which are technically connected to each other via a polygonal body 4. Advantageously, the polygonal body 4 is formed as a quadrilateral body. By operating one of the handles, a bolt in a lock provided in the door leaf is operated and the door leaf is released (opening the door). Conventionally, a bolt is also provided below the bolt in order to lock the door. The bolt can be operated in different ways, for example by using a cylinder operable by means of a key or electronically or by means of a knob, which is mounted in the door leaf below the handle. In any case, the bolt prevents the door from being opened in the locked state.

[0030] However, in certain applications, it is not necessary to provide a door that can be locked by a latch. For example, in the interior of an apartment, for example in a bedroom or a child's room, or in a working area such as an office or a home office, or in a bathroom, etc., a simpler locking device may be sufficient, in particular in order to achieve privacy. In these cases, it is not necessary to be able to lock and unlock the door from both sides at all times. In order to provide a suitable solution for this application, the following handle 11 and a door handle assembly 1 having a handle 11 and a corresponding counterpart (Gegenstück) (handle 10) are proposed.

[0031] In all the embodiments described below, the handle 11 is arranged on the outside of the door and is referred to below as the outer handle 11. The outer handle 11 is not removable and is pre-mounted on the door leaf. Here, the base plate 2 and the outer handle 11 are already fixedly (but detachably) joined to each other, so that from the other side of the door, only the polygonal body 4 has to be introduced floatingly, which is advantageously connected to the handle 10 formed as an inner handle 10, in order to complete the door handle assembly 1.

[0032] When the polygonal body 4 on the opposite side, i.e. the inside of the door, is operated, i.e. moved axially, in all embodiments, the blocking is achieved by at least one latching pin 40 of the polygonal body 4 on the base plate 2 (fixed to the door leaf) of the outside handle 11. This can be done, for example, by the inside handle 10 fixed to the polygonal body 4. Thus, by the axial movement of the inside handle 10 on the inside of the door, the radial blocking of the outside handle 11 on the outside of the door is achieved.

[0033] The fixedly mounted unit consisting of the base plate 2, the outer handle 11 fixed thereto and the polygonal body 4 (latching pin 40) enables a positive locking / blocking through all three components. In the non-latching / blocking state, the components outer handle 11 and polygonal body 4 (latching pin 40) move together in the radial direction as a unit.

[0034] The polygonal body 4 forms a form-fitting unit together with the outer handle 11 and the base plate 2. The inner handle 10 is not an essential part of the invention, since the polygonal body 4 can also be operated manually by movement in the axial direction X. However, in order to complete the door handle assembly 1, the inner handle 10 is usually provided.

[0035] The two handles (inner handle 10 and outer handle 11 ) can be formed identically or differently, for example as cranks, knobs or in another type and manner.

[0036] The following will describe in detail the various components and working principles of the door handle assembly.

[0037] As mentioned above, in all embodiments, the outer handle 11 and the base plate 2 are fixedly connected to each other (fixed in the axial direction and movable in the radial direction) to form a preassembled unit. This is achieved, for example, by providing the outer handle 11 with a ball joint and a bayonet connection (Bajonettverschluss) arranged in the flange 110 (for accommodating / connecting to the base plate 2), by which the base plate 2 is mounted and fastened in a form-fitting manner with the corresponding flange 24 (formed from the base plate 2). In the middle of the flanges 110, 24, a through hole is provided for accommodating the polygonal body 4 so that the polygonal body 4 engages with the outer handle 11 and establishes an operative connection. The fixing of the polygonal body 4 on the outer handle 11 is achieved, for example, by a threaded connection as known in the prior art, which can also be used as an emergency release 3.

[0038] The polygonal body 4 is inserted into the components that are fixedly (but detachably) connected to each other, namely the outer handle 11 and the associated base plate 2, and is connected thereto, and has at least one latching pin 40 that protrudes orthogonally (relative to X). Advantageously, two latching pins 40 are provided on the body of the polygonal body 4, which are arranged 180° opposite to each other. The latching pins 40 are advantageously formed in one piece with the polygonal body 4. Two latching pins 40 are always described below. Advantageously, a quadrilateral body is provided as the polygonal body 4.

[0039] The latching pin 40 is arranged on one side of the outer handle 11 and is operatively connected to both the outer handle 11 and the base plate 2. To this end, the flanges of the base plate 2 and the outer handle 11 have grooves that overlap each other in the zero position of the outer handle 11, and the grooves are used to accommodate the latching pin 40. The zero position means that neither handle 10, 11 is operated.

[0040] In the non-blocking state (the first position of the polygonal body 4), when one of the handles 10, 11 is operated, the latching pin 40 moves freely and is not blocked / blocked. In the blocking state (the second position of the polygonal body 4), a partial area of ​​the base plate 2, in particular a part of its flange 24, serves as a blocking portion, and the latching pin 40 is blocked thereon as far as possible without any clearance (the blocking element 20 and the blocking element 23 described below block the latching pin 40 in the radial direction).

[0041] The basic principle is to release the locking pin 40 of the polygonal body 4 by movement in the axial direction X, i.e. pressing and pulling, or to prevent radial movement in a predetermined movement direction (for opening the door) by stopping on the locking element 20 of the base plate 2, i.e. to establish a locked state. Here, the locking element 20 and the locking pin 40 are advantageously formed as vertical surfaces, which abut against each other in the locked state. Thus, a large-area and reliable locking is provided.

[0042] In all embodiments, the handles 10 , 11 are prevented from being able to move in a direction opposite to the operating direction in both the locked and unlocked states by a blocking element 23 of the base plate 2 arranged opposite the direction of movement. The blocking element 23 is advantageously part of a flange 24 of the base plate 2 .

[0043] Two embodiments are described below to provide latching.

[0044] exist Figures 1 to 10 A first embodiment is shown in . In this embodiment, locking is achieved by pressing the polygonal body 4 in the axial direction (in the direction of the outer handle 11 ).

[0045] Figure 1 , Figure 2 , Figure 3 and Figure 6 The handle assembly is shown in an unlocked, non-operating state. Figure 4 , Figure 5 and Figure 7 The handle assembly is shown in the unlocked, operated state, ie the outer handle 11 is moved in the (radial) direction of movement. Before locking, ie in the freely movable state, one or more latch pins 40 slide within the operating radius during operation.

[0046] In the freely movable (non-blocked) state, the latching pin 40 can freely move radially in a predetermined direction and distance (as is customary for handles 10 , 11 ). Figure 1 The complete handle assembly is shown in an oblique view, ie with the two handles 10, 11 in the assembled state, but without the intermediate door leaf in the inoperative state. The outer handle 11 is shown in a sectional view. Figure 2 and Figure 4 The oblique views of the complete handle assembly are shown respectively. Figure 3 and Figure 5 The oblique cross-sectional views of the complete handle assembly are shown respectively. Figure 6 and Figure 7 Shown from Figure 2 and Figure 4 2 is an enlarged view of the area of ​​the base plate 2. It can be clearly seen here that the latching pin 40 is located above the locking element 20 and can therefore move freely in the operating direction. In the direction opposite to the operating direction, a blocking element 23 is provided.

[0047] The locking / latching is achieved in the zero state by applying axial pressure from the inside to the handle 10 on the inside of the door (i.e. the inner handle 10). This causes the latching pin 40 to snap into place between the blocking element 23 of the base plate 2 and the latching element 20, as shown in FIG. Figure 8 , Fig. 9 and Fig.10As shown. Here, the locking element 20 serves as a stop for one or more latching pins 40 in the radial movement direction. As a result, radial movement of the door handle (handles 10 and 11) is no longer possible. The lock is then released again by pulling the handle 10 on the inside of the door leaf.

[0048] The second preferred embodiment is Fig.11 and 12 . In this embodiment, locking is performed by pulling the polygonal body 4 towards the inside of the door, i.e. away from the door leaf. Therefore, in this embodiment, locking is achieved by pulling the polygonal body 4 (in the axial direction X) on the inside of the door, in particular by the inner handle 10 (if present). In this embodiment, the flange 24 of the base plate 2 has an undercut (Hinterschnitt) in the direction of movement of operation and directly adjacent to the groove. This leaves an opening (groove) between the base plate 2 and the upper edge of the flange 24, in which the latching pin 40 is guided in the non-latched state. The height of the opening corresponds to the height of the latching pin 40, and is advantageously slightly higher to ensure smooth passage. In addition, the length of the opening (in the direction of movement) is limited to achieve a restriction of the radial movement of the handles 10, 11.

[0049] In the locked state, the latch pin 40 is held in the groove of the flange 24 of the base plate 2. At this time, the side of the groove that acts in the movement direction serves as the locking element 20 and thus as a stop for the latch pin 40. The other side of the groove serves as a blocking element 23.

[0050] This embodiment has the advantage that accidental locking cannot occur when the door is closed from the inside, since the direction of movement of the lock is opposite to the direction of closing the door.

[0051] In all embodiments, as is common in the prior art, two top posts 21 are provided on the base plate 2, which are arranged opposite one another, and which are inserted into through holes in the door and can be screwed into bolts of the fastening plate 101 of the handle 10 on the inside of the door. The height of these top posts 21 is at least the same as the height of the flange 110 of the outside handle 11 and the flange 24 of the base plate 2, and is advantageously slightly higher. In addition to the two top posts 21, optional additional supporting top posts can also be provided, which are preferably offset by 90 degrees to the top posts 21 (located on the same circumference) and are also arranged opposite one another. These supporting top posts can, for example, be screwed into prepared threaded openings 22 of the base plate 2, as shown in FIG. Fig.11 and 12As shown, it is used as an additional component. The height of the support posts advantageously corresponds to the height of the posts 21. As with the posts 21, corresponding holes must also be provided in the door leaf, but these holes do not have to be through-holes through the door leaf, because the support posts only have to provide support for the forces acting on the outer handle 11. These support posts are therefore additional rotation stops. However, they also serve to distribute the forces acting on the outer handle 11 more evenly, in particular when an attempt is made to operate the outer handle 11 with greater force in the locked state.

[0052] Furthermore, in all embodiments, a combination of a bolt 31 and a long hole 32 is provided in the region where the polygonal body 4 of the outer handle 11 engages, which also serves as an emergency unlocking portion 3. The combination is advantageously arranged on the lower side of the outer handle 11, which is not a visible side. At this time, a long hole 32 is provided in the outer handle 11 along the axial direction X, into which a bolt 31 is inserted, and the bolt 31 engages with the polygonal body 4, that is, is screwed therein. The long hole 32 is used to ensure that the bolt 31 can also move when the polygonal body 4 moves axially, so that no locking is formed. At the same time, the long hole 32 serves as a movement restriction of the polygonal body 4 in the axial direction X. Here, the long hole 32 and the bolt 31 are coordinated with each other in such a way that a guide that is as free of play as possible is formed, but the movement in the axial direction X is smooth. For this purpose, the diameter of the long hole 32 is selected to be slightly larger than the diameter of the bolt 31. In one embodiment, the bolt 31 protrudes slightly from the long hole 32. When the emergency release 3 is required, the bolt 31 can be used to move the polygonal body 4 from the locked position to the freely movable position by axial displacement. No special tools or screwdrivers are required. The bolt 31 can be moved by any object, such as a key, a coffee spoon, a fingernail, etc., as long as the necessary force can be applied by the object.

[0053] Furthermore, in all embodiments, at least one hole for receiving a ball-shaped catch 5 can be introduced in the region of the outer handle 11 into which the polygonal body 4 engages. When the polygonal body 4 is actuated, i.e. moved in the axial direction X, the ball-shaped catch is inserted into the hole in the outer handle 11 and snaps into the corresponding snap groove 42 audibly for the user with its ball end. The at least one ball-shaped catch 5 is advantageously arranged on the underside of the outer handle 11, which is not the visible side.

[0054] In all embodiments, one or more lock indicators may be provided. In this case, a lock indicator may be provided on the inner side of the door to indicate to the user whether the door is locked. In addition, a lock indicator may be provided on the outer side to indicate to the user viewing the door from the outside whether the door is locked.

[0055] The locking indicator, i.e., the indicator of the open state or the closed state, may not be installed on or at the handles 10, 11, but may be installed on or as a layer 80 behind the flower-shaped seat or in the direction of the door leaf, such as in Figure 1 In the figure, for all other embodiments, it is shown representatively in the area of ​​the inner handle 10. Here, in the area between the door leaf (more precisely the flower-shaped seat) and the handle 10, 11, for example, a colored marking is provided.

[0056] The locking indicator, i.e., the indicator of the open state or the closed state, can be installed on or at the handle 10, 11, such as at Figure 1 1 is shown in the region of the outer handle 11 representatively for all embodiments. Here, on the upper side of the outer handle 11, i.e. on the visible side, in the region above the polygon 4, an observation window 811 as a hole is provided. In this region, a display element 81 is provided, which is, for example, colored. As soon as the polygon 4 moves, the display element 81 is moved, and the display (e.g., color) of "open" or "locked" appears in the observation region of the observation window 811. Different embodiments are conceivable, in which the colored display can appear in both the locked state and the non-locked state, or only in one of the states.

[0057] In order to obtain a complete door handle assembly 1 and to be able to easily operate the polygonal body 4, two handles 10, 11 are usually provided, one of which is arranged on the inside of the door (inner handle 10) and the other is arranged on the outside of the door (outer handle 11). As mentioned above, the two handles 10, 11 are in operative connection via the polygonal body 4. Basically, any inner handle 10 can be used as the inner handle 10 for operating the proposed locking device, because the inner handle is only used to axially move the polygonal body 4. The locking mechanism is arranged in the area of ​​the outer handle 11, so that no changes to the inner handle 10 are required. According to the invention, a groove 60 known from the prior art (such as the outer handle 11) which is screwed into the inner handle 10 is also used. Figure 3 , Figure 5 and Fig. 9 As an example, a screw is provided to connect the inner handle 10 to the polygonal body 4 and to move it in one direction (away from the door) so as to establish an active connection between the inner handle 10 and the polygonal body 4. It can be provided that the polygonal body 4 has a bore 41 in its interior in its outer region, such as Figure 3 , Figure 5 and Fig. 9As also shown by way of example, the bore 41 is formed in such a way that the resulting inner wall of the polygonal body 4 is thinner in the region into which the screw is screwed. This allows the screw to penetrate the inner wall and establish a better connection with the polygonal body 4. In addition, a self-locking latching device 70 can be provided, which blocks the handle 10 in one direction (before it is pulled out of the polygonal body 4). This self-locking latching device 70 is already known and will not be described further.

[0058] Thus, it is proposed that the locking of the door on the outer handle 11 is caused by operating the inner handle 10. Thus, a separate door bolt is no longer required, so that the door handle assembly consists of only one unit. The door handle assembly is used in areas where a certain degree of privacy is required, as mentioned at the beginning.

[0059] This requires that the door handle on the inside can be axially moved as a unit connected to the quadrilateral body in order to then lock on the outside without the need for additional levers, buttons or anything else. The door handle itself serves as an operating element. Blocking / locking on the outside makes sense because the pressure in the locked state is mainly applied to the outside, while in the prior art the locking is done on the inside; no one wants to come in from the inside. As a result, the lever effect leading to the locking becomes higher. In addition, compared to the prior art, the locking as part of the quadrilateral body acts doubly, i.e. top and bottom: i.e. by at least two locking elements, wherein more locking elements are conceivable. The area of ​​the blocking locking element (latching pin 40) is doubled, balanced, and provides a durable, reliable locking and safety function.

[0060] The known systems all have a quadrilateral body pin that is greatly weakened by holes and grooves. This is very complicated to produce, is accordingly vulnerable to interference and can hardly be reliably manufactured in mass production, and the subsequent installation on the door and the adjustment of the door thickness are also very complicated. Where static (Statik) is required, the proposed quadrilateral body always remains intact and solid. Compared with DE 20 2021 106 925 U1, the external handle no longer moves with the movement, but is a unit that is fixedly connected to all other external components. In DE 202021 106 925 U1, the movement should move the entire handle unit through many different elements, and at the same time many assembly errors that affect the function should be expected. The outside is delivered completely preassembled and there are no more "unknowns", thus eliminating inaccurate assembly, errors, etc. Door thicknesses can be easily covered like in normal components. This preassembly makes assembly very fast and can also be carried out by laymen (Laien) without any problems and easily. A wide variety of door thicknesses can also be covered, and it is not dependent on the lock seat or other requirements given by the customer. Visually, these components remain unchanged, except for the "occupied" display on the outside and the "open" display on the inside, which fits perfectly into the overall picture. Optionally, an emergency unlocking part 3 can be introduced on the outside.

[0061] In addition, the embodiments and advantages of the present invention are described as follows:

[0062] - The units to be moved are clamped and screwed into units only after assembly

[0063] - The unit meets all the stipulated requirements (emergency release, lock / unlock indication, locking, unlocking, adjustment of operating force, etc.)

[0064] - In addition to providing a safe lock, the top and bottom latches also have the task of concentrating the force when trying to open the locked state

[0065] - The operating force can be adjusted steplessly via an external pressure piece

[0066] - Existing door handle is used as the locking operator, no additional buttons or sliders are required to lock

[0067] - Emergency release prevents accidental locking or unlocking from the outside using everyday objects (coins, pens, keys, knives, forks, etc.)

[0068] -Requires minimal installation space inside the door and flower-shaped seat

[0069] - Extremely simple and cost-effective to produce (few parts, easy to manufacture)

[0070] The following characteristics are also required:

[0071] -Door handle assembly operable from the inside and lockable from the outside

[0072] - Axial movement of components / units

[0073] - No through holes in the quadrilateral body (drilled holes or grooves from the inside to the outside) / stationary / stability (important for higher use category certification)

[0074] - Locking / engaging centrally rather than eccentrically (distribution of forces)

[0075] - No adjustments required for different door thicknesses or lock positions

[0076] The invention is further based on the following performance requirements, which also describe their advantages:

[0077] 1. Installation status:

[0078] Traditional internal door with lock with 8 / 8.5mm sleeve head. Door thickness 38-45, folded, blunt. Door thickness must be covered with only one pin. Maximum installation space in the door is 22x 7mm diameter, better 5mm.

[0079] 2. Assembly:

[0080] Assembly is by no means a challenge for the layman, as assembly errors must be excluded in the design.

[0081] (Preferably delivered pre-assembled at the factory)

[0082] 3. Installation space and appearance:

[0083] The installation space (including clamping) for a 5 mm thick rosette must be sufficient. Any known rosette diameter and any known rosette thickness over 5 mm must be feasible. Looks like an existing component. The red / white indicator on the handle must be clearly visible. Not head-to-head (Vorkopf)!

[0084] 4. The lock can be unlocked from the outside by blocking radial movement and by disengaging the quadrilateral body. Control from the inside after closing must provide reliable feedback about the closing status.

[0085] 5. No small parts!

[0086] 6. The design must be simple and intuitive to operate, providing maximum stability and safety. The closing and opening process must give clear feedback. A click or snap feeling.

[0087] 7. In the locked state, when attempting to operate, the lock tongue can move inwards up to 0.5mm. Ideally, blocking and disengagement at the same time can be considered.

[0088] 8. The intensity of the operation must be determined, including the possible occasional use of violence.

[0089] 9. Unintentional locking or unlocking must be excluded. This also applies to actuation from the outside.

[0090] 10. The emergency release must be operable as hassle-free as possible using everyday objects. However, it must not be freely and obviously accessible. There must be some kind of "game inhibition" here.

[0091] 11. EN 1906 user category strives to be at least level 3 and level 4, excluding level 1.

[0092] 12. Blocking must occur on the outside where the greatest pressure is applied, rather than on the inside of a handle assembly where the operator only makes a control attempt to determine if it is locked.

[0093] 13. All defects of the prior art known to the customer and identified by us must be completely resolved.

[0094] 14. The screws are M4 to M5 at most.

[0095] 15. The button solution must be feasible. Fixed or rotatable is also acceptable.

[0096] 16. Quadrilateral bodies shall not be weakened by milling or drilling

[0097] 17. Can be operated without gap in the non-locking state (minimum user level is 3, 200,000 cycles).
