Description

A handle that can be locked on one side is disclosed, the locking being effected by means of axial displacement of an axially displaceable locking part.

Handles are known in the prior art, in which the entire handle (handle set) is moved axially, for example from the DE 20 2021 106 925 U1 . There it is disclosed that both handles of the handle set form a connected, axially displaceable unit together with a polygon and grub screws. The design is complex in terms of construction and must be installed individually in each case.

The object of the invention is to simplify the construction and installation of handle sets and to produce a more stable blocking effect.

This object is solved by the features of the independent claim. Advantageous configurations are the subject matter of the dependent claims.

A door handle set is proposed, having a first handle formed as an external handle, a base plate connected thereto with at least one locking element, and a polygon with at least one locking pin that can be brought into engagement with the base plate and external handle. By moving the polygon in the axial direction, the latching pin interacts with the at least one locking element in such a way that the outer pusher blocks movement in a predetermined radial direction of movement in a first position of the polygon and blocks movement in a predetermined radial direction of movement in a second position of the polygon is released.

Furthermore, it is provided that the polygon has two locking pins located opposite one another, and that two locking elements are provided.

Furthermore, it is provided that in an area of the outer handle in which the polygon engages, an elongated hole is provided in the outer handle and a threaded hole is provided in the polygon in the area of the elongated hole, with a screw also being provided which passes through the elongated hole in the hole is screwed with thread.

Furthermore, it is provided that at least one hole is provided in an area of the outer handle into which the polygon engages, and in the area of the polygon where the at least one hole is provided, at least one latching groove is provided for each position of the polygon, and wherein a ball detent is provided for each hole, which is arranged in such a way that it engages in the at least one detent groove depending on the position of the polygon.

Furthermore, it is provided that the door handle set also has an inside handle, which can be brought into engagement with an area of the polygon opposite the outside handle in such a way that it is in operative connection with it and can actuate the polygon in the radial direction in order to move the polygon into the first position and bring to the second position.

Furthermore, it is provided that a blocking element protruding from the base plate is provided, which is arranged in such a way that the movement of the at least one locking pin is thereby limited in the radial direction and counter to the predetermined radial direction of movement.

Furthermore, it is provided that the door handle set also has two opposing domes protruding from the base plate, as well as two opposing supporting domes that are offset from the domes and are introduced into threaded holes in the base plate and protrude therefrom.

Furthermore, it is provided that the door handle set also has at least one locking indicator arranged on a handle, which is visible or not visible depending on the position of the polygon, and which is located either between the area of the handle that faces a door leaf and a rosette is provided and formed as a colored layer, or is provided on a visible side of the handle, wherein the handle has a hole in an area above the polygon, and wherein a display element is attached to the polygon in the area of the hole, which by moving the polygon in axial direction pushes a display in the area of the opening of the hole or out of the area of the opening of the hole.

Furthermore, it is provided that the base plate, outer handle and polygon are positively connected to one another.

In the following descriptions of the figures, the same elements or functions are provided with the same reference symbols.

Handle sets 1 for operating e.g. doors are well known. They consist of two handles 10, 11 arranged on one side of a door, more precisely of the door leaf, which are operatively connected to one another via a polygon 4. The polygon 4 is advantageously formed as a square. By actuating one of the handles, a latch in the lock provided in the door leaf is actuated and the door leaf is released (opening the door). Conventionally, a bolt is also provided below the latch to lock the door. This can be operated in different ways, e.g. by using a cylinder that can be operated with a key or electronically or with a rotary knob, which is installed below the handle in the door leaf. In any case, the bolt prevents the door from being opened when it is locked.

However, in some applications it is not necessary to provide a latchable door. For example, in the interior of an apartment, e.g. in the bedroom or children's room, or in work rooms such as offices or home office rooms, or in toilets, etc., a simpler locking system can be sufficient, in particular to allow privacy. In these cases it is not necessary to be able to lock and unlock the door from both sides at any time. In order to provide a suitable solution for this application, the handle 11 described below and a door handle set 1 with the handle 11 and the corresponding counterpart (handle 10) are proposed.

In all of the embodiments described below, the handle 11 is provided on the outside of the door and is referred to below as the outside handle 11 . The outside handle 11 cannot be moved and is pre-assembled on the door leaf. The base plate 2 and the outer handle 11 are already firmly (but detachably) engaged with one another, so that from the other side of the door only the polygon 4, which is advantageously connected to a handle 10 designed as an inner handle 10, has to be brought in floating in order to Door handle set 1 to complete.

In all versions, locking takes place by means of at least one latching pin 40 of the polygon 4 on the base plate 2 (attached to the door leaf) of the outside handle 11 if the polygon 4 is operated on the opposite side, i.e. the inside of the door, i.e. is moved axially . This can be done, for example, with an inside handle 10 attached to the polygon 4. An axial displacement of the inside handle 10 on the inside of the door thus results in a radial blocking of the outside handle 11 on the outside of the door.

The fixed unit consisting of the base plate 2, the outer handle 11 fixed to it and the polygon 4 (locking pin 40) enables positive locking/blocking by all three components. When not locked/blocked, the components outer handle 11 and polygon 4 (locking pin 40) move together as a unit in the radial direction.

The polygon 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 polygon 4 can also be operated manually by being moved in the axial direction X. In order to complete the door handle set 1, however, an inside handle 10 is usually provided.

The two handles (inside handle 10 and outside handle 11) can be formed in the same way or differently, e.g. as a pawl, knob or in some other way.

The individual components of the door handle set and how it works are described in detail below.

As already mentioned, in all versions, the outer handle 11 and the base plate 2 are firmly connected to one another (axially fixed, radially movable) in order to form a preassembled unit. This is done, for example, by the external handle 11 having a ball joint provided in a collar 110 (for receiving/connecting to the base plate 2) and a bayonet catch, via which the base plate 2 is applied in a form-fitting manner to a corresponding collar 24 (formed from the base plate 2) and is attached. In the middle of the collars 110, 24 there is a passage for receiving the polygon 4 in order to bring it into engagement with the outer handle 11 and establish the operative connection. The attachment of the polygon 4 to the outside handle 11 takes place, as is known from the prior art, e.g. via a screw connection, which can also serve as an emergency release 3.

The polygon 4, which is introduced into the components, external handle 11 and associated base plate 2, which are firmly (but detachably) connected to one another and is connected thereto, has at least one locking pin 40 protruding orthogonally (to X). Advantageously, two locking pins 40 lying opposite one another by 180 degrees across the body of the polygon 4 are provided. The locking pins 40 are advantageously formed in one piece with the polygon 4 . Two locking pins 40 are always described below. A square is advantageously provided as a polygon 4 .

The latching pins 40 are provided on the side of the outer handle 11 and are operatively connected both to the outer handle 11 and to the base plate 2 . For this purpose, the collars of the base plate 2 and the outer handle 11 have grooves lying one above the other in the neutral position of the outer handle 11 for receiving the locking pins 40 . Zero position means that none of the handles 10, 11 is operated.

In the unlocked state (first position of the polygon 4), the locking pins 40 are moved freely when operating one of the handles 10, 11 and are not blocked/locked. In the locked state (second position of the polygon 4), a partial area of the base plate 2, in particular part of its collar 24, serves as a lock on which the locking pin 40 is blocked with as little play as possible (locking element 20 and the blocking element 23 described below block the locking pin 40 in the radial direction Direction).

The basic principle is that the latching pins 40 of the polygon 4 are released by moving in the axial direction X, i.e. pushing or pulling, or radial movement in the specified direction of movement (to open the door) by hitting a locking element 20 of the base plate 2 is prevented is, so a locked state is established. The locking element 20 and the latching pin 40 are advantageously formed as a vertical surface which rests against one another in the locked state. This provides a large area and secure locking.

In all versions, a blocking element 23 of the base plate 2 arranged counter to the direction of movement also prevents the handles 10, 11 from being able to be moved in the opposite direction to the direction of actuation, both in the locked and in the unlocked state. The blocking element 23 is advantageously part of the collar 24 of the base plate 2.

Two implementations are described below to provide the locking.

A first version is in 1 until 10 shown. In this version, the locking takes place by pressing the polygon 4 in the axial direction (towards the outer handle 11).

In 1 , 2 , 3 and 6 is a state of the handle set in the unlocked, not actuated state shown. In 4 , 5 and 7 a state of the handle set in the unlocked, actuated state is shown, ie the outside handle 11 is moved in the (radial) direction of movement. Before a blockage, ie in the freely movable state, the locking pin(s) 40 slide within the operating radius during actuation.

In the freely movable (unlocked) state, the locking pins 40 can move radially freely in a predetermined direction and distance (as is usual with handles 10, 11). 1 shows an oblique view of a complete handle set, ie with both handles 10, 11, in the assembled state, but without an intermediate door leaf, in the non-actuated state. The outside handle 11 is shown in section. 2 and 4 each show an oblique view of a complete set of handles. 3 and 5 each show an oblique sectional view of a complete handle set. 6 and 7 show an enlarged view 2 or. 4 in the area of the base plate 2. It can be clearly seen here that the latching pins 40 are located above the locking element 20 and are therefore free to move in an actuating direction. The blocking element 23 is provided in the direction opposite to the direction of actuation.

The blocking/locking takes place in the zero state by means of axial pressure from the inside on the handle 10 on the inside of the door, i.e. the inside handle 10. This causes the locking pin 40 to engage between the blocking element 23 and the locking element 20 of the base plate 2, as in 8th , 9 and 10 shown. The locking element 20 serves as a stop for the locking pin or pins 40 in the radial direction of movement. A radial movement of the door handle (the handles 10 and 11) is then no longer possible. The blockage is then released again by pulling on the handle 10 on the inside of the door leaf.

A second preferred embodiment is in 11 and 12 shown. In this version, the locking takes place by pulling the polygon 4 towards the inside of the door, ie away from the door leaf. In this embodiment, the locking is done by pulling (in the axial direction X) the polygon 4 on the inside of the door, in particular by means of the inside handle 10, if present. In this embodiment, the collar 24 of the base plate 2 has an undercut in the direction of movement of the operator and directly adjacent to the groove. This leaves an opening (groove) between the base plate 2 and the upper edge of the collar 24, in which the locking pin 40 is guided in the unlocked state. The opening has a height that corresponds to the height of the locking pin 40, which is advantageously slightly higher in order to ensure ease of movement. In addition, their length (in the direction of movement) is limited in order to enable the radial movement of the handles 10, 11 to be limited.

In the locked state, the latching pin 40 is held in the groove of the collar 24 of the base plate 2. The side of the groove that acts in the direction of movement serves as a locking element 20 and thus as a stop for the locking pin 40. The other side of the groove serves as a blocking element 23.

This design has the advantage that when the door is closed from the inside, no accidental locking can take place, since the direction of movement of the lock is opposite to the direction in which the door is closed.

In all versions, as is customary in the prior art, two opposing domes 21 are provided on the base plate 2, which are introduced into passages in the door and can be screwed into the screws of the fastening plate 101 of the handle 10 on the inside of the door. These domes 21 are at least as high as the collar 110 of the outer handle 11 and the collar 24 of the base plate 2, but are advantageously slightly higher. In addition to the two domes 21, additional supporting domes that are preferably offset by 90 degrees to the domes 21 (lying on the same circumference) and also lying opposite one another can optionally be provided. These can, for example, be inserted into prepared threaded openings 22 in the base plate 2, as shown in 11 and 12 indicated, are screwed so that they serve as an additional component. Their height advantageously corresponds to the height of the dome 21. As for the dome 21, corresponding holes must be provided in the door leaf, which, however, do not have to be leadthroughs through the door leaf, since the support domes only have to provide support for forces acting on the outside handle 11 . These support domes are therefore both an additional anti-twist device. However, they also serve to distribute the forces acting on the outside handle 11 more evenly, in particular if an attempt is made to operate the outside handle 11 in the locked state with greater force.

In addition, a combination of screw 31 and slot 32 that also serves as an emergency release 3 is provided in all versions in the area of the outside handle 11, in which the polygon 4 engages. The combination is advantageously arranged on an underside of the outside handle 11, which is not a visible side. In this case, an elongated hole 32 is provided in the axial direction X in the outer handle 11, in which a screw 31 is inserted, which is in engagement with the polygon 4, so is screwed there. The oblong hole 32 is used so that the screw 31 can also move when the polygon 4 moves axially and thus does not form a lock. At the same time, the elongated hole 32 serves as a movement limiter in the axial direction X for the polygon 4. The elongated hole 32 and screw 31 are matched to one another in such a way that guidance is provided with as little play as possible, but the movement in the axial direction X is still smooth-running. For this purpose, the diameter of the elongated hole 32 is to be chosen slightly larger than that of the screw 31 . In one embodiment, the screw 31 projects minimally out of the elongated hole 32 . If an emergency release 3 is required, this screw 31 can be used by axial displacement to move the polygon 4 from the locked position to the freely movable position. No special tools or screwdrivers are required. The screw 31 can be used with anyone Object to be moved, such as a key, a teaspoon, a fingernail, etc., as long as the necessary force can be applied.

In addition, at least one hole for receiving a ball catch 5 can be introduced in all versions in the area of the outer handle 11 in which the polygon 4 engages. This is introduced into a hole in the outer handle 11 and its spherical end snaps into a corresponding locking groove 42 audibly for a user when the polygon 4 is operated, ie is displaced in the axial direction X. The at least one ball catch 5 is advantageously arranged on an underside of the outside handle 11, which is not a visible side.

One or more lock indicators may be provided in all embodiments. Here, a lock indicator can be provided both on the inside of the door to indicate to the user that the door is locked or not locked. A lock indicator can also be provided on the outside to indicate to a user looking at the door from outside whether the door is locked or not.

The locking indicator, i.e. the indicator of the open or closed state, can, for example, not be attached to or on the handle 10, 11, but on or as a layer 80 behind the rosette or oriented in the direction of a door leaf, as in 1 shown as representative of all other designs in the area of the inside handle 10 . In the area between the door leaf, more precisely the rosette, and the handle 10, 11, a colored marking is provided, for example.

The locking indicator, i.e. the indicator of the open or closed state, can be attached, for example, to or on the handle 10, 11, as in 1 shown as representative of all versions in the area of the outside handle 11 . Here, a viewing window 811 is provided as a hole in an area above the polygon 4 on the upper side of the outer handle 11, ie on the visible side. A display element 81 is provided in this area, which is colored, for example. As soon as the polygon 4 is moved, this display element 81 is moved and the "open" or "locked" display (e.g. color) appears in the field of view of the viewing window 811. Different versions are conceivable in which a colored display is displayed both in the locked and in the appears in the unlocked state or only in one of the states.

In order to obtain a complete door handle set 1 and to be able to operate the polygon 4 easily, two handles 10, 11 are usually provided, one of which is on the inside of the door (internal handle 10) and the other on the outside of the door ( Outside handle 11) is provided. The two handles 10, 11 are operatively connected via the polygon 4, as already described. Essentially any inside handle 10 can be used as the inside handle 10 for operating the proposed locking device, since it is only used for the axial displacement of the polygon 4 . The locking mechanism is arranged in the area of the outer handle 11, so that no changes to the inner handle 10 are necessary. The grub screw known from the prior art, which is screwed into a recess 60 in the inside handle 10, as exemplified in 3 , 5 and 9 drawn in to connect it to the polygon 4 and to move it in one direction (away from the door), is also used according to the invention to establish the operative connection between the inside handle 10 and polygon 4 . Provision can be made for the polygon 4 to have a bore 41 in its interior in an outer region, as also shown in FIG 3 , 5 and 9 drawn in, which is formed in such a way that the resulting inner wall of the polygon 4 is thinner in the area in which the grub screw is screwed in. This means that the grub screw can even pierce through the inner wall and form a better connection with the polygon 4. In addition, a self-locking lock 70 can be provided, which blocks the handle 10 in one direction (before it is pulled out of the polygon 4). This self-locking lock 70 is already known and will not be described further.

It is therefore proposed to lock a door on the outside handle 11 by actuating the inside handle 10. A separate bolt is therefore no longer necessary, so that the door handle set consists of only one unit. The door handle set is used in areas where a certain degree of privacy is desired, as already described in the introduction.

It is therefore claimed that the door handle can be moved axially on the inside as a connected unit with the square in order to then lock on the outside - and that without an additional lever, button or anything else. The door handle itself is used as an actuating element. Blocking/locking up the outside makes sense because the pressure in the locked state is predominantly on the outside - the prior art locks on the inside; where no one wants to go. Thus, the leverage that comes on the lock becomes far higher. Furthermore, the blocking, which is part of the square, has a double effect, in contrast to the prior art, i.e. both above and below: by at least two locking elements mente so, with more locking elements are conceivable. The area of the blocking elements (locking pins 40) that block is doubled, balanced and ensures a permanent, reliable blocking and secure function.

The known systems all have square pins that are severely weakened by holes and grooves. This is highly complicated to manufacture - correspondingly vulnerable and hardly reliable to produce in series, and then highly complicated to mount on the door and also to adjust the door thickness. The proposed square remains full and solid throughout, precisely where statics are required. In contrast to DE 20 2021 106 925 U1 the handle on the outside is no longer moved, but is a firmly connected unit with all other external components. At DE 20 2021 106 925 U1 the displacement would have had to move the overall pusher unit through many different elements and at the same time one would have had to deal with many assembly errors affecting the function. Inaccurate assembly, errors, etc. are eliminated because the outside is delivered completely pre-assembled and there are no longer any "unknowns". As with normal sets, door thicknesses are easily covered. Due to this pre-assembly, assembly can be carried out very quickly and without any problems, even by laypersons. A wide variety of door thicknesses can also be covered and there is no dependency on the lock seat or other on-site requirements. The sets are optically unchanged - apart from the "occupied" display on the outside and "open" display on the inside - and they fit perfectly into the overall picture. An emergency lock (3) can be installed on the outside as an option.

   • There must be enough space for a 5 mm thick rose including clip. Every known rosette diameter and every known rosette thickness over 5 mm must be feasible. Optics like the current sets. The red/white indicator must be clearly visible on the handle. Not forehead!
4. 4. The blockage can be released by blocking the radial movement or by disengaging the square on the outside. The check from the inside after closing must provide reliable feedback on the closed state.
5. 5. No small or very small parts!
6. 6. The construction must be easy and intuitive to use and provide maximum stability and safety. The closing and opening process must give clear feedback. A click or snap sensation.
7. 7. When locked, the latch may move in no more than 0.5mm when attempted. Ideally, you can think about blocking and disengaging at the same time.
8. 8. Operator forces must be determined. Possible occasional use of force included.
9. 9. Unintentional locking or unlocking must be ruled out. As is manipulation from the outside.
10. 10. The emergency release must be as barrier-free as possible to use with an everyday object. However, it must not be freely and visibly accessible. There has to be a certain “game inhibition” here.
11. 11. EN 1906 user category Class 3 minimum, Class 4 without Class 1 is to be aimed for.
12. 12. The blockage must be on the outside, where the greatest pressure is exerted. Not like with Griffwerk inside, where the operator only tries to check whether it is locked.
13. 13. All complaints about the state of the art that are known to our customers and determined by us must be completely cured.
14. 14. Screw M4 max. M5.
15. 15. Button solutions must be feasible. Fixed as well as rotatable.
16. 16. No weakening of the square through milling or drilling
17. 17. Backlash-free actuation when unlocked (class of use 3 min. 200,000 cycles).
