Description

The invention relates to the field of fittings for doors, more precisely to a lever handle for actuating a lock.

Here and in the following, door handle means a device for actuating a lock, in particular a door lock. The actuation of the door handle can allow the door to be opened in a direction in which the door is moving (pressure), or can be opened in a direction in which the door is approaching (train). For the sake of simplicity, the term "pusher" is used in both cases.

Lever handles are combined with standard locks, typically mortise locks. The movement or power transmission from the door handle to the standard lock takes place via a lock shaft, which has a square and rotates around a transmission axis. The lock shaft can be designed as a separate element or can be included in the standard lock or can be included in the door handle. The lock shaft is inserted in a follower. The trigger nut is a central, round insert in the lock (the term "lock nut" is used for this below). The inserted lock sits in a lock pocket worked out in a door leaf and is screwed to the door leaf on a so-called cuff. After actuating the door handle, a nut spring also ensures Called a spring, hereinafter referred to as a lock spring, to indicate that the lock nut, square (also the lock shaft) and lever handle move back to the starting position.

Usual door handles which act on the lock shaft to actuate a door lock are often designed as pawls. Such door handles or door handles are usually compact and fixed at a certain position on the door. Accordingly, it is not possible for everyone to operate the known compact door handles in an ergonomic manner or even to reach them at all. For example, people of different sizes cannot all operate the same door handle well or operate it at all. A known compact door handle cannot be optimally positioned for all needs and / or be easy to use for all persons from every position, position and / or position. Due to the lever law, known door handles are not equally easy, equally easy and / or equally easy to operate at every point of attack on this door handle.

Or other known door handles such as panic bars extend over a relatively wide area of a door. Such panic bars can only be triggered by pressure and can therefore only be used on a pressure side of a door, but not on a pull side of a door or on both sides of a door. In addition, panic bars are designed to be very robust and correspondingly large and heavy, so they require a lot of space on the door and place demands on the robustness of the door and its anchoring. In addition, panic beams are architecturally mostly difficult to integrate into an overall concept. Panic bars are also perceived as aesthetically unappealing.

It is therefore an object of the invention to provide a lever handle of the type mentioned at the beginning which at least partially eliminates at least one of the disadvantages mentioned above.

This task is solved by a door handle with the features of the corresponding independent claim. Advantageous embodiments can be found in the dependent claims, the description and / or the figures.

• ein längliches Betätigungselement,
• zwei quer zu einer Längsachse des Betätigungselements abstehende Distanzelemente, um das Betätigungselement beabstandet an der Türe zu befestigen und um mindestens eine Öffnung für mindestens einen Teil einer Hand zwischen Betätigungselement und Distanzelementen sowie der Türe auszubilden,
• einen Bewegungsmechanismus, welcher eine relative translatorische Bewegung zwischen Betätigungselement und jedem der beiden Distanzelementen erlaubt,
• einen Öffnungsmechanismus, welcher die relative translatorische Bewegung des Betätigungselements in eine Drehung des Übertragungselements um die Übertragungsachse umsetzt.

The door handle according to the invention is suitable for opening a door by actuating a lock shaft which is formed separately from the door handle and rotates about a transmission axis or a lock nut which is formed separately from the door handle and rotates about a transmission axis. In this case, a transmission element of the lever handle is arranged to be rotatable about the transmission axis. The door handle also features:

• an elongated actuator,
• two spacer elements projecting transversely to a longitudinal axis of the actuating element, in order to fasten the actuating element at a distance to the door and to form at least one opening for at least part of a hand between the actuating element and spacer elements and the door,
• a movement mechanism which allows a relative translational movement between the actuating element and each of the two spacer elements,
• an opening mechanism which converts the relative translational movement of the actuating element into a rotation of the transmission element about the transmission axis.

This lever handle is designed to open a door. The door handle includes an elongated actuator, two spacers, one Movement mechanism, a transmission element and an opening mechanism.

The door handle can include a lock shaft. The door handle can be designed free of a lock shaft.

The elongated actuating element extends in a ready-to-operate (ie assembled) state over a predetermined wide area of a door, which also enables a predetermined group of different users to reach and use the door handle. The actuating element can be designed in such a way that it is precisely adapted to a wide range of different ergonomic requirements of a predetermined group of users. For example, people of certain different sizes can operate all of these door handles well, if at all, due to the elongated actuating element and the resulting coverage of a wide operating range.

The elongated actuating element can cover a large operating area due to its elongated spatial extension. This allows the lever handle to be operated well from many positions, positions and / or positions.

The elongated actuating element extends along its longitudinal axis over at least 50 centimeters. In particular, the actuating element extends along its longitudinal axis over at least 100 centimeters. The actuating element can extend along its longitudinal axis over at least 150 centimeters.

In particular, the longitudinal axis of the actuating element is arranged transversely to the transmission axis in an initial position of the door handle. In the initial position of the door handle, the longitudinal axis of the actuating element can be arranged orthogonally to the transmission axis.

With the starting position, a position of the door handle is to be opened before the door handle is actuated, that is to say before the actuating element moves around the door.

The two spacer elements are arranged so as to protrude transversely to a longitudinal axis of the actuating element. The two spacer elements are spaced apart from one another along the longitudinal axis of the actuating element. The spacer elements serve the purpose of fastening the actuating element to the door at a distance. As a result, at least one opening is formed for at least part of a hand between the actuating element and spacer elements and the door.

Such an opening makes it possible to reach behind the actuating element for operation at least partially with at least parts of one hand and / or even to enclose at least partially (or in other words at least partially enclose). This has the advantage of being ergonomic. The actuating element can be gripped well. In this way, the actuating element can be actuated safely, firmly and / or comfortably. The actuating element can be actuated under pressure. By at least partially reaching behind and / or enclosing the actuating element during operation, actuating the actuating element (and thereby the door) is possible in a pull.

Thanks to this opening, the lever handle can be used on the pull side of a door. The door handle can be designed to open a door on a train.

The door handle can also be used on the pressure side of a door. The door handle can be designed to open a door under pressure.

Such a lever handle can therefore be used both on the pull side of a door and on the pressure side of a door. This enables a symmetrical appearance.

Such a lever handle can be architecturally integrated into an overall concept. Such a lever handle is perceived as more aesthetically pleasing than a panic bar.

The movement mechanism allows a relative translational movement between the actuator and each of the two spacers. The relative movement between the spacer element and the actuating element means a spacing or approach between the actuating element and the spacer element.

The relative translational movement when actuating the door handle can be an approximation of the actuating element and the spacer element. Such a lever handle is suitable, for example, for opening a door under pressure.

In particular, the relative translational movement when actuating the door handle is a spacing between the actuating element and the spacer element. Such a lever handle is suitable, for example, for opening a door on a train.

The lever handle optionally includes a rail guide. The rail guide comprises a slide and a rail and allows a controlled translational movement. The rail guide can ensure stable and reliable guidance of the movement of the actuating element. For example, a slide is attached to the actuator and a rail to the spacer.

The moving mechanism allows the actuator to move relative to both spacers. In this way the door handle can be used in this way be designed so that the actuating element can be operated in a manner customary for door handles, despite its elongated spatial extension, without the actuating element colliding with the door. When operating the door handle, it can be prevented that parts of the actuating element come too close to the door and / or create potentially dangerous situations for a user (for example, a danger of being pinched). On the other hand, this also prevents parts of the actuating element from being distantly distant from the door. This could be problematic for reasons of space and / or negatively affect the ergonomic operation of the lever handle.

The movement mechanism makes it possible to use an actuating element which is spatially widely extended. With this actuating element, a spatial operating area can be covered, which meets a wide range of different ergonomic requirements of a predetermined group of users.

The opening mechanism converts the relative translational movement of the actuating element into a rotation of the transmission element about the transmission axis. In this way, movement of the actuating element relative to spacer elements triggers rotation of the transmission element. This in turn actuates the lock of the door and the door can be opened.

The opening mechanism thus uses a movement of the actuating element to make the transmission element rotate. The opening mechanism can directly tap the relative translational movement of the actuating element and convert it into the rotation of the transmission element, or indirectly (for example by using a converted translational movement of the actuating element that has already been converted, that is, by picking up another movement coupled with it).

In particular, both the point in time and the extent of the deflection of the rotation of the transmission element and the energy required for this are directly coupled to the movement of the actuating element.

An electrical switching process is optionally carried out by rotating the transmission element.

By electrical switching operation it is meant that an electrical contact is made or interrupted.

The electrical switching process can trigger an electrical signal when the door handle is operated. The operation of the door handle can be monitored. The actuation of the door handle can trigger processes such as the actuation of an electrically operated locking device by the electrical switching process.

In particular, the opening mechanism comprises a helical backdrop guide. This helical backdrop guide converts the translational movement into a rotational movement.

In particular, the actuating element is designed such that it can be encompassed by an average-sized hand of an adult person at least halfway across the longitudinal axis of the actuating element.

For example, the actuating element is dimensioned such that it can be encompassed by an average-sized hand of an adult human being at least three quarters of its circumference transversely to the longitudinal axis of the actuating element. The actuating element can be dimensioned in this way be that it can be completely encompassed by an average-sized adult's hand transverse to the longitudinal axis of the actuating element.

For example, the circumference across the longitudinal axis of the actuating element is more than ten and less than twenty centimeters.

An at least partial embracing of the actuating element allows a secure and firm grip. This enables safe and reliable operation of the lever handle.

According to the invention, the movement mechanism comprises a coupling mechanism. This coupling mechanism couples a relative movement between the actuating element and a first of the two spacer elements with a relative movement between the actuating element and the second of the two spacer elements.

In particular, the coupling mechanism also works the other way round, which means that it acts in both directions (from the first to the second spacer element, but also at the same time vice versa from the second to the first spacer element).

A coupling of the relative movements between the actuating element and spacer elements allows a controlled and uniform movement of the actuating element when operating the door handle. In this way, a movement path of the actuating element can be deliberately kept within predetermined limits. Mechanical problems such as canting can be prevented by controlling the movement of the actuator through the coupling mechanism.

The coupling mechanism can also be used to specifically and controlledly prevent collisions of the actuating element with the door. It is the same through the Coupling mechanism possible to prevent parts of the actuating element from coming too close to the door and / or creating potentially dangerous situations for a user (for example a danger of being pinched). The coupling mechanism can prevent parts of the actuating element from being distantly distant from the door, which can be problematic for reasons of space and / or can negatively influence the ergonomic operation of the door handle.

The coupling mechanism allows the door handle to be designed to be precisely adapted to a wide range of different ergonomic requirements of a predetermined group of users. For example, people of different sizes can operate this lever handle at different points (or in other words at different points of attack) in a specifically predetermined manner. The actuating element can therefore cover a large operating area in which the lever handle can be operated well. It is therefore possible to operate the lever handle well from many positions, positions and / or positions.

Alternatively, the door handle can be designed free of a coupling mechanism. The relative translational movement between the actuating element and each of the two spacer elements can be independent of one another.

Optionally, the coupling mechanism is designed as a positive guide to ensure an analog relative movement between one of the two spacer elements and the actuating element.

The extent and the direction of the relative movement of the actuating element to each of the two spacer elements are the same size because of the positive guidance. In other words, the positive guidance ensures that a movement of the actuating element relative to the one spacer element is the same size and is the same direction as a corresponding movement of the actuating element relative to the other spacer. In other words, the positive guidance means that any movement of the actuating element relative to the first spacer element results in an analogous movement of the actuating element relative to the second spacer element and vice versa. A movement of the actuating element therefore takes place parallel to a straight line spanned by analog points of the two spacer elements.

In this way, the positive guidance prevents the actuating element from tilting in the lever handle.

The path of movement of the actuating element is specifically predetermined by the positive guidance, so that the actuating element is always arranged parallel to the spacer elements and thereby usually also to the door during its movement. This ensures ergonomic operation. In this way, the functioning of the door handle fulfills a frequent expectation of a user who does not know the door handle. In other words, a lever handle functions in the usual and expected manner because of the forced guidance if the actuating element runs through a movement path parallel to the spacer elements and in particular to the door. The lever handle can be operated in an easy to understand and intuitive way.

Due to the positive guidance, the lever handle is equally simple, equally easy and / or equally easy to operate at every point of application of the actuating element. The lever handle can be operated equally well along the entire spatial extent of the actuating element due to the positive guidance.

Because of the forced guidance, the actuating element can be designed to be precisely adapted to a wide range of different ergonomic requirements of a predetermined user group. For example, people of different sizes can use all these door handles in different places (or in other words, at different points of attack) in the same way. The actuating element can thus cover a large operating area in which the lever handle can be operated just as well. It is therefore possible to operate the lever handle well from many positions, positions and / or positions.

Alternatively, the relative translational movement between the actuating element and the first spacer element can differ from the relative translational movement between the actuating element and the second spacer element and can nevertheless be coupled to one another. Such an asymmetrical and coupled movement of the actuating element relative to both spacer elements and thus in a ready-to-operate condition also to a door can be used to specifically set up operating areas with different operating parameters (for example the extent of the deflection and / or the necessary force).

Optionally, the coupling mechanism is at least partially encompassed by the actuating element, and a force transmitted by the coupling mechanism is transmitted from one spacer element to the other within the actuating element.

In this context, being included means being spatially encompassed.

In particular, the coupling mechanism for transmitting the force has an element which is different from the actuating element and which is at least partially spatially encompassed by the actuating element.

Transferring the force within the actuating element has the advantage that the lever handle can be made compact. The coupling mechanism at least partially encompassed by the actuating element allows ergonomic trained door handles with advantageously arranged openings close to the door for reaching behind the actuating element.

Such a compact door handle can be architecturally integrated into and / or adapted to an overall concept. Such a lever handle is perceived as more aesthetically pleasing than a panic bar.

Alternatively, the coupling mechanism can have elements that exert its entire force transmission exclusively outside the actuating element.

Optionally, the coupling mechanism comprises a coupling element which is configured differently from the actuating element, which is spatially completely encompassed by the actuating element, and which transmits the force transmitted by the coupling mechanism within the actuating element.

In particular, the coupling element extends essentially from a first spacer element to a second spacer element within the actuating element.

Extending essentially from the first to the second spacer element here means that the coupling element extends at least over 70% of a distance between the first and the second spacer element along the longitudinal axis of the actuating element. The coupling element can also extend over at least 80% of this distance. In particular, the coupling element extends over 90% of this distance. The coupling element can also extend over at least the entire distance between the first and second distance elements.

A coupling element, which transmits the force of the coupling mechanism within the actuating element, allows a space-saving, safe and secure way of transmitting force. The arrangement of the coupling element within the actuating element protects the coupling element from external influences. The arrangement of the coupling element within the actuating element enables actuation of the actuating element without running the risk of being damaged by the force transmitted by the coupling mechanism.

Optionally, the coupling mechanism comprises a coupling element which partially or completely transmits the force transmitted by the coupling mechanism by a rotational movement of the coupling element.

In particular, the coupling element rotates about an axis of rotation which is arranged essentially parallel to the longitudinal axis of the actuating element.

Essentially parallel here means that a maximum angle of 5 degrees is included. In particular, a maximum angle of 10 degrees is included. The maximum included angle can be 15 degrees. The axis of rotation of the coupling element can be arranged parallel to the longitudinal axis of the actuating element.

The essentially parallel or parallel arrangement allows a space-saving arrangement of the coupling element.

A rotating coupling element for power transmission of the coupling mechanism allows the coupling element to be compact. A rotating coupling element is a space-saving, robust and reliable way of transmitting power. Simple construction and low manufacturing costs are advantages of a rotating coupling element. The whole door handle can be on this Formed in a compact basic form. The basic shape can be easily varied if it is compact.

In particular, the rotating coupling element is arranged within the actuating element. This enables a compact design of an actuating element which comprises the coupling element. The advantages of power transmission in the actuating element are described above and add to the advantages of the rotating coupling element.

For example, the coupling element extends over a distance which essentially corresponds to a distance between the distance elements. In other words, the coupling element can be approximately the same length as a distance between the spacer elements. This enables a compact design of the actuating element.

Alternatively, the power transmission of the coupling mechanism can take place free of a rotational movement. For example, through a translational movement.

The movement mechanism optionally includes an eccentric mechanism which converts the relative translational movement between the spacer element and the actuating element into the rotational movement of the coupling element and vice versa.

An eccentric mechanism is a compact and robust way of converting the relative translational movement into the rotational movement. Simple design, few components and high reliability are advantages of the eccentric mechanism. The eccentric mechanism allows large forces to be transmitted and can be manufactured inexpensively.

Alternatively, the conversion of the relative translational movement into the rotational movement can take place without an eccentric mechanism. For example, a mechanism including gears and rack can be used to convert the relative translational motion to the rotational motion.

The spacer elements are optionally arranged along the longitudinal axis of the actuating element in its end regions.

In other words, the spacer elements are located in the end regions of the actuating element. In this way, the actuating element can be attached to the door in a stable and well supported manner. If a coupling mechanism is present, the coupling of the relative translational movements can attack the ends of the actuating element, which is mechanically advantageous and makes tilting difficult.

Alternatively, a spacer element or both spacer elements are arranged in the region of the center of the actuating element.

The opening mechanism is optionally arranged between the spacer elements in a projection onto a longitudinal axis of the actuating element.

In particular, the door handle thus forms at least two openings for at least part of a hand, in each case between the actuating element, the opening mechanism and the spacer element and the door.

An arrangement of the opening mechanism between the spacer elements (when viewed in projection on the longitudinal axis of the actuating element) allows the actuating element to extend in opposite directions from the lock of the door. This means that a large operating area can be covered.

In particular, the door handle forms exactly two through openings for at least part of a hand, in each case between the actuating element, opening mechanism and spacer element and the door.

Alternatively, when viewed in a projection onto the longitudinal axis of the actuating element, the opening mechanism is formed outside a region between the spacer elements. For example, the opening mechanism can be formed in and / or on the spacer element.

The lever handle optionally includes a reset mechanism. This reset mechanism is designed such that the actuating element can be moved into an initial position relative to the spacer elements before and / or after actuation of the door handle.

The reset mechanism ensures that the lever handle returns to its original position after the lever handle has been operated. So after the lever handle has been actuated, the door handle is automatically brought back to the starting position by moving the actuating element. This offers a high level of operating convenience and serves for safety (since the opening mechanism is brought back into a state that keeps the door closed). A manual closing of the door handle is not necessary and cannot be forgotten. The reset mechanism enables an ergonomic overall sequence when opening the door, since the lever handle or the actuating element does not have to be moved back in the opposite direction after opening.

Alternatively, the door handle can be designed without a reset mechanism.

Another aspect of the invention is a door comprising a door lock and a door handle according to the invention as described above. The door lock includes a split lock nut.

The properties and advantages of the lever handle are described above and continue to apply.

A split lock nut in the door lock enables the lever handles to move independently on the pull and push side. A first lever handle fastened to the lock can be actuated by pull and a second lever handle fastened to the lock can be actuated by pressure, the second lever lever remaining in its starting position during operation of the first door lever and vice versa.

The lever handle on the inactive side of the door remains in its starting position due to the split lock nut and does not move unexpectedly or surprisingly. In this way, potentially dangerous and surprising situations can be avoided, for example if the door handle is attempted to operate simultaneously from both sides at the same time or in quick succession.

Alternatively, the lock nut in the door can also be made in one piece.

In this door, the door lock optionally includes a lock cylinder which, viewed in a vertical projection on a flat side of the door, is arranged offset to the actuating element.

In other words, the lock cylinder is arranged laterally offset from the actuating element. This enables simple, safe and quick access to the lock cylinder. The actuating element does not hinder access to the lock cylinder. The danger of that when operating the door body parts and / or objects are pinched is reduced. In this way, the risk of injury can be minimized.

Alternatively, the lock cylinder, viewed in a vertical projection on the flat side of the door, can be arranged partially or entirely within the actuating element. In this way, the lock cylinder lies between the door and the actuating element. This is a space-saving arrangement. This can also be preferred for design reasons.

Optionally, in the ready-to-operate state, the actuating element has a longitudinal axis arranged parallel to the direction of gravity.

In other words, the actuating element is arranged vertically on the door in its initial position. A vertical arrangement of the longitudinal axis of the actuating element allows the lever handle to cover a wide area of the door with respect to an ergonomic operating height. A lever handle arranged parallel to the vertical door edge also has the advantage of being easy to insert into overall architectural concepts and, at the same time, having a high level of functionality (good usability in a wide operating range).

Alternatively, the longitudinal axis of the actuating element can also deviate from an orientation parallel to the direction of gravity.

In principle, the same parts are provided with the same reference symbols in the figures. Unless stated otherwise, the designations on the left, right, below and above refer to the drawing level of the figures.

In Figure 1 is a perspective view of a first embodiment of a door handle 1 is shown. Parts and elements of this lever handle 1 are from Figure 1 has been removed to allow a better overview and a clearer view of an internal structure of the lever handle 1.

This first embodiment of the door handle 1 is designed to open a door under pressure. The door handle 1 comprises an elongated actuating element 2. Two spacer elements 3 are attached transversely to a longitudinal axis L of the actuating element 2, each along the longitudinal axis L in the end regions of the actuating element 2. An opening mechanism 6 is arranged between the two spacer elements 3. The opening mechanism 6 is connected to a transmission element 5 and can set this in rotation. The transmission element 5 in turn transmits its rotation to a lock shaft 7, which is arranged rotatably about a transmission axis U.

The movement mechanism 4 allows the actuating element 2 to move relatively translationally to the two spacer elements 3 from an initial position when the door handle 1 is operated, namely moving away from the spacer elements 3. The movement mechanism 4 has a coupling mechanism and couples the movements of the upper and the lower spacer element 3 to one another. The coupling mechanism of the movement mechanism 4 is even designed as a positive guide. This means that every movement of the actuating element 2 relative to the upper spacer element 3 is also carried out by the lower spacer element 3 and vice versa. The coupling mechanism comprises a coupling element 10, which is spatially encompassed by the actuating element 2 and, parallel to the longitudinal axis L, transmits power to the coupling mechanism.

The movement mechanism 4 also has an eccentric mechanism, which comprises an eccentric disk 11 and an eccentric lever 12 for each spacer element 3. The eccentric lever 12 is attached to the spacer element 3 at one end and to the eccentric disk 11 at an opposite end thereof. The eccentric disk 11 is radially centered on the coupling element 10 perpendicular to an axis of rotation of the coupling element 10 and is rotationally fixed attached. In this way, the eccentric disc 11 and the eccentric lever 12 allow the eccentric mechanism to convert the relatively translational movement of the actuating element 2 away from the spacer elements 3 into a rotational movement of the coupling element 10. Since the eccentric disks 11 and the eccentric levers 12 are each dimensioned and arranged analogously in the case of the two spacer elements 3, a positive guidance is thereby formed.

The opening mechanism 6 in turn converts the relative translational movement of the actuating element 2 into a rotation of the transmission element 5 about the transmission axis U. For this purpose, the opening mechanism 6 is formed in two parts and is fastened to the actuating element 2 with a first part. The opening mechanism 6 is fastened to the door with a second part, this part also comprising the transmission element 5. The first part of the opening mechanism 6 is connected to the second part of the opening mechanism 6 by elements with a helical backdrop guide 13. This helical backdrop guide 13 converts the movement of the actuating element 2, which moves together with the first part of the opening mechanism 6, into a rotation of the transmission element 5 in the second part of the opening mechanism 6, which does not move relative to the spacer elements 3.

Figure 2 shows a side sectional view of the door handle Figure 1 . The elements described above and their interaction are clearly visible. Particularly recognizable in Figure 2 is the reset mechanism, which is formed by coil springs 14. The coil springs 14 are positioned between the actuating element 2 and the spacer element 3. The coil springs 14 are compressed when the door handle 1 is operated, that is to say when the actuating element 2 is removed from the spacer elements 3, and exert a restoring force thereon when the actuating element 2 is released. In this way, the actuating element 2 and thus the entire door handle 1 returns to its starting position before the door handle 1 is operated the orthogonal arrangement of the longitudinal axis L of the elongate actuating element 2 with respect to the transmission axis U can be seen.

The coupling element 10 is designed, for example, as a straight, rigid rod. It is rotatable in a coupling element guide 20 but is fixed in place on the actuating element 2. And so that the actuating element 2 maintains a controlled trajectory during its relative translational movement with respect to the spacer elements 3, a rail guide is formed in each spacer element 3. The rail guide comprises a slide 21, which is fastened to the actuating element 2, and a rail 22, which is fastened to the spacer element 3. The rail guide ensures safe, stable and reliable guidance of the movement of the actuating element 2 relative to the spacer elements 3 along a precisely predetermined movement path.

In the Figures 3, 4 and 5 detailed views of parts of the movement mechanism 4 of the first embodiment of the door handle 1 are shown. Figure 3 shows a perspective view of a section of the lever handle 1 Figure 1 , with the upper spacer 3 and without slide guide. Figure 4 shows the same (but with slide guide) in a side sectional view, as well Figure 5 in a sectional view from above.

Figures 6 and 7 each show detailed views of the opening mechanism 6 of the first embodiment of the door handle 1. In Figure 6 is a perspective view of the opening mechanism, and Figure 7 shows a side sectional view of it.

A second embodiment of the lever handle 1 is shown in Figure 8 shown in a perspective view. This second exemplary embodiment shows a lever handle which is designed to open a door on a train. The main difference from the first embodiment is that of an analog Starting position from the actuating element 2 in the first exemplary embodiment approaches the spacer elements 3 and thus shortens the distance to a door. The spatial dimensions of the entire lever handle 1 are thus reduced by pressing it. In the second exemplary embodiment, the situation is exactly the opposite: when the door handle 1 is operated by pull, the actuating element 2 moves away from the spacer elements 3 and thus also from the door. In this way, when operating this exemplary embodiment of the door handle 1, the total spatial dimensions of the entire door handle 1 increase relative to its starting position. The functions of the movement mechanism and the opening mechanism are analogous in both exemplary embodiments.

Such as Figure 8 of the Figure 1 corresponds analogously, corresponding to the Figures 9 to 14 analogous to those from 2 to 7.

In Figure 15 is a perspective view of a door 30 each with a door handle 1 of the first and the second embodiment. The door handles 1 each extend over the entire height of the door 30 and are arranged vertically (that is, with the longitudinal axis of the actuating elements 2 parallel to the direction of gravity). The lock cylinder 31 is arranged on the door 30 laterally offset from the actuating element 2. In other words, the lock cylinder 31, viewed in a vertical projection on a flat side of the door, is arranged offset to the actuating element 2. This offset is clearly visible in Figure 16 , which is a sectional view too Figure 15 from above shows. The lever handle 1 is arranged on the left, while the lever lever 1 is on the right. The lock cylinder 31 is arranged on the side of the door handle 1 on the door 30.

The embodiments shown show elongated actuating elements in the form of straight rods. In other embodiments, the elongate actuators may be curved, and a curved longitudinal axis, the shape of the Following actuator, have. The coupling element 10, if present, can be designed as an elastic shaft.
