Description

The invention relates to a foot door opener and a door according to the preamble of claims 1 and 17 having a foot door opener according to the invention.

Such a foot strike and a door equipped with it is from the US 2011/0225890 A1 known. The foot-operated door opener has a foot-surface element that is translationally movable in the door plane as a slide. A lateral projection serves as a driver for vertical actuation and transmits a force to the door opening mechanism, while the return movement is effected by a spring element.

DE 101 13 865 A1 discloses a device for opening a door, in particular in the wet cell area, an actuating member serving for actuation with the foot being provided in the door, the actuating member being designed as a rod projecting from the door.

EP 1 048 811 A1 discloses in particular a door opening system equipped with a foot switch, which is arranged next to the door, wherein an actuator rod acts directly on a door opening mechanism.

WO 02/31297 A1 discloses a door opening mechanism which translates a footstep translation into a rotational movement of an organ directly engaging a door opening mechanism.

US 5,193,863 A and US 4,569,546 A disclose a foot door opener, which is arranged in a flap on the door, so that by actuating by stepping on a foot on a plate-shaped and rotatable foot pedal element, an actuator rod carries out a translational movement, so that it can then be opened by engaging an opening mechanism of the door.

US 4,621,848 A discloses a foot door opener in which a user can actuate a pedal-shaped foot element which projects from the door, so that it can be opened by engaging in a translational movement from top to bottom directly via an actuator rod on an opening mechanism of the door.

DE 10 2010 035 554 B4 discloses a foot door opener, with a foot actuator element arranged in the lower region on a door, for opening the door, the foot actuator element having an upper and a lower foot surface element, these being connected to one another in an articulated manner and pivoting at least partially into the interior of the door when the foot is actuated.

Except for the last-mentioned foot door opener, these foot door opening devices known from the prior art have in common that on the one hand they allow a relatively coarse and not finely metered opening of the door by means of a foot and, moreover, they are associated with a certain potential for injury during operation due to the fact bulky geometries. In the case of the last-mentioned foot door opening device, this is for the most part turned off, but not completely, so that the problem of the invention is therefore to provide a foot door opening device of the same type, which in particular can be adjusted and finely metered opening and closing possibilities of a door in a certain range to the respective applications provides.

This problem underlying the invention is solved by a foot door opener according to the invention according to claim 1 and by a door according to claim 17.

The foot door opener according to the invention is arranged in use in the lower region of a door, a rotary actuation element rotatingly interacting with an interaction element of the door opening mechanism when the foot panel element is actuated, such that when the foot panel element is released and at least partially retracted, the rotary actuation element is interaction-free with respect to the interaction element and that when actuated of the footprint element, the rotary actuating element rotates onto a stop element of the door opening mechanism, the stop element being thereby displaced in translation and thus interacting with a door lock mechanism.

The door lock mechanism itself is not part of the foot-operated door opener according to the invention, but rather part of a door, but when the foot-operated door opener is installed, a corresponding interaction then takes place in functional terms.

The interaction between the foot door opener and the door lock mechanism occurs, for example, and in particular in that a downward force is exerted on the door lock mechanism via an actuation transmission element in the form of a steel cable, so that this is possible when the foot panel element is completely moved down and thus also completely within the door opening mechanism Moving a fastening part downwards by turning a door handle support bar opens and thus releases the corresponding door. Here, for example, and in particular a lever firmly connected to the door handle rotating rod is important, on which the steel cable engages at the upper end of the steel cable, in order to translate upward or downward translatory movements into a rotary movement of the doorbell rotating rod, so that instead of pressing a door handle down, the Door handle pivot bar rotates accordingly to actuate the door lock mechanism to release the door to open it.

Due to the fact that when the base element is pulled back, which is pulled back into its starting position, for example, and in particular by means of a pull-back element in the form of a spring, this mechanically separates from the door opening mechanism and thus no longer interacts with the door opening mechanism, then only the door lock mechanism interacts and the door opening mechanism with each other, so that this already enables a very delicate mechanical closing of the door or the door lock mechanism in a corresponding frame of a corresponding door frame, since the retracting force of the retraction element of the footplate element as part of the foot actuator mechanism then no longer additionally acts on the door lock mechanism ,

In this context, it is particularly advantageous if the door opening mechanism has damping, for example and in particular if the door opening mechanism is damped by at least two damping elements which are moved or moved in a mutually damping manner, it being particularly advantageous because of the particularly good implementation in practice , if the traversing or movability is of a translatory nature, so that, for example and in particular the damping elements are rod-shaped damping elements which move into and away from one another by means of friction.

A particularly proven embodiment consists in and is therefore advantageous if the overrun element is firmly connected to a first slide part, the first slide part being forcibly synchronized with a second slide part which is in use with respect to the direction of displacement of the first Sled part of the opposite translational direction is shifted.

In this context, it has proven useful that the forced synchronization is implemented by means of a gearwheel, in that teeth of the gearwheel act as actuators in the opposite translational direction, both on teeth arranged linearly in the first slide part and on teeth linearly arranged in the second slide part.

In this context, it is particularly advantageous if both slide parts are used during the translatory displacement of the slide parts over at least one guide rail element, for example and in particular as part of the base element, in order to ensure particularly reliable translational displacement of the damping elements.

With regard to the damping, it is furthermore advantageous if the damping of the door opening mechanism and / or the foot actuator mechanism is realized in that both slide parts are moved or can be moved translationally damping with respect to one another by means of at least two damping elements that are displaced in one another, damping or movable.

It is also advantageous if the door opening mechanism is designed in such a way that when the foot panel element is moved in the direction of the end position - i.e. the position that corresponds to the complete passage of the foot panel element - the force required to release the door lock mechanism for opening the door becomes lower compared to force to be applied when moving the foot panel element from the initial position in order to provide a particularly convenient opening functionality in this way.

In this context, it is advantageous because it has been proven that the reduction in the force to be applied is realized by a first magnetic element of the door opening mechanism being moved of the base element in the direction of the end position is magnetically interacting with a ferromagnetic element of the door opening mechanism or a second magnetic element of the door opening mechanism, it having proven particularly useful in practice if the first magnetic element is attached directly or indirectly to the second slide part and the second magnetic element or The ferromagnetic element is fastened to a base element that is not fastened to the first slide part or to the first slide part, or vice versa, so that when the footplate element is moved, the magnetic interaction leads to the two slide parts moving apart with a time delay and / or being magnetically damped when the footplate element is released from the end position ,

It is also advantageous if the door opening mechanism has a force element which is such that when the footplate element is released, the door opening mechanism is actuated into a door opening mechanism starting position and thus brings the door lock mechanism into a load-free position, for example and in particular the force element being a spring element acts, which presses the two slide parts apart into their respective slide end positions, for example and in particular the spring element engages both on a fastening part fastened with the second slide part and also on a base element fastened with the first slide part, so that when the footplate element is released, both the fastening part and the second slide part are pressed into their respective end positions. Pressing into the respective end positions serves to ensure that the door lock mechanism advantageously engages securely in the corresponding frame of a door frame and thus securely closes the door.

In this context, it is advantageous if a Magnetic interaction element is adjustable in the direction of translation of the slide parts, for example and in particular by turning this engagement element, the translational position is adjustable and thus also the applied force, which acts on the fastening part and on the second slide part in the end positions.

Furthermore, it is advantageous if the door opening mechanism is designed such that when the door lock mechanism is locked in the closed position when the flow surface element is actuated, the non-positive connection between the door lock mechanism and the door opening mechanism is released from a certain applied force, this being achieved, for example, and in particular by the fact that the lifting of the Non-positive connection is realized in that a non-positive magnetic element and a ferromagnetic non-positive element are non-positively connected and can be pulled apart from a certain applied force.

In this context, it is advantageous if both non-positive connection elements are arranged in fastening parts in order to provide a space-saving solution for this.

Furthermore, it is advantageous if in this context the friction magnetic element is the first magnetic element, since such an embodiment has proven to be extremely safe and ergonomic in practice.

1. a) das Türarretierungsmagnetelement direkt anliegt an einem Türrahmenmagnetelement oder einem magnetischen Türrahmenelement oder
2. b) das magnetische Türarretierelement direkt anliegt an dem Türrahmenmagnetelement, sodass die Schließposition der zu schließenden Tür hierdurch zusätzlich gesichert wird.

It is also advantageous, since it has been tried and tested in practice, if the foot door opener has a door locking mechanism that locks it in an open door position by means of magnetic interaction, for example, and in particular it is advantageous if a door locking magnet element or a magnetic door locking element is translationally displaceable, in the non- locked state

1. a) the door locking magnet element bears directly on one Door frame magnetic element or a magnetic door frame element or
2. b) the magnetic door locking element rests directly on the door frame magnetic element, so that the closed position of the door to be closed is thereby additionally secured.

Finally, it is advantageous if, in the locked state, the door locking magnet element or the magnetic door locking element is drawn into the door by means of a locking magnet element, or in the locked state, the door locking magnet element is drawn into the door by means of a magnetic door release element.

In the locked state, a rod-shaped element, which is in particular magnetically connected to the door locking magnet element or the magnetic door locking element, locks the gear wheel due to the abovementioned magnetic interaction by striking a run-up surface of the gear wheel on the rod-shaped element. In this way, the door lock mechanism remains open, which corresponds to a depressed door handle.

In Figure 1 A perspective top view of an embodiment of the foot door opener according to the invention can be seen. The foot door opener essentially has a foot actuator mechanism 1, which also includes a foot surface element 3, which is designed as a lower foot surface element and is articulated with a further, upper foot surface element 50 in a (not shown) Backdrop is movable and sometimes also moves outwards when stepping down - also outside the frame. With regard to the foot actuator mechanism, the full content of the DE 10 2010 035 554 directed. The foot strike according to the invention essentially differs from that in FIG DE 10 2010 035 554 disclosed by the completely different door opening mechanism 2, which consists of different individual elements.

The door opening mechanism 2 essentially consists of a rotary actuation element 5, an interaction element 6, which is also designed and numbered here as a ramp element 7, a first slide part 8, a second slide part 9, a gearwheel 10 (in Figure 3 ), two damping elements 11, 12 that can be moved in a mutually translatory manner, a first magnetic element 13, which functions as a force-locking magnetic element 22 and is located in a fastening part 19 and interacts magnetically with a ferromagnetic force-locking element 23, the ferromagnetic element 14 also acting as a second magnetic element 15 can be configured and both embodiments function as an engagement element 21 with regard to the magnetic interaction. The engagement element 21 is firmly connected with a small translational play with a base element 16 which is fixedly attached to the frame of the foot door opener.

When the foot surface element 3 is stepped down, it is pivoted downward within the link 70, the translationally pivoting movement of the foot surface element 3 being converted into a rotational movement (here: inverted direction of rotation relative to the pivoting movement direction of the foot surface element 3) of the rotary actuating element 5, which is mounted on the frame inner part in a rotationally mounted manner, wherein due to the elongated design of the rotary actuation element 5, this acts as a lever, on the interaction element 6, which acts as an overrun element 7 designed and part of the first carriage part 8.

Due to the translational displacement of the first slide part 8 upwards (when the foot panel element 3 swivels downwards and thus when a corresponding door is opened), forced synchronization via the gearwheel 10 with the second slide part 9 ensures that the second slide part 9 is in position first slide part 8 in the opposite translatory direction, namely downwards, because gearwheels 43 of the gearwheel 10 engage in teeth 41 of the first slide part 8 arranged in translation and teeth 42 of the second slide part 9 arranged in translation.

The gear 10 is rotatably supported in the base element 16.

As a result of the forced synchronization, the two slide parts 8 and 9 thus move in opposite directions along a guide rail element 71 when the footplate element 3 is moved downwards or when the footplate element 3 is released and the force acting on the door lock mechanism 4 is released.

When the second slide part 9 is moved down, the fastening part 19 also moves downward to a corresponding extent, an actuation transmission element in the form of a steel cable 53 exerting a downward force on the door lock mechanism 4, so that when the base element 3 is fully moved down and thus also the complete movement of the fastening part 19 downward within the door opening mechanism 2 opens the door lock mechanism and thus releases the corresponding door. The steel cable 53 engages with a rotary lever element 102 which is connected in a rotationally fixed manner to a door handle rotating rod 101, so that in this way, instead of the door handle 100 being pressed down, the door 103 is now released by rotating the rotary lever element 102.

In order to prevent overloading or even destruction of the door opening mechanism 2 when the door lock mechanism 4 is locked, for example by holding a door handle (not shown) in the closed position of the door lock mechanism 4 when the foot panel element 3 comes down, the ferromagnetic force-locking element 23 is located inside the fastening part 19 , which is connected directly to the actuation transmission element in the form of a steel cable 53 and, within a relatively narrow limit, translationally separates from the force-locking magnetic element 22 within a relatively narrow limit and is thus translationally displaceable within a narrow limit (the magnetic element 22 is fixed to the underbody of the fastening part 19 connected). After a corresponding separation of the friction magnetic element 22 from the ferromagnetic Force-locking element 23 can then be non-positively connected to one another again by approaching by depressing a (not shown) door handle of the door lock mechanism.

The damping of the translational movements of the two slide parts 8 and 9 is realized by the two damping elements 11 and 12, which can be moved in a mutually translational manner, whereby a second pair 11 'and 12' is additionally provided for damping the foot actuator mechanism 1 and thus the foot surface element 3. The damping element 11 is connected to the slide part 9 via a rod-shaped force transmission element 55 on one side, the corresponding damping element 12 being fastened to a frame 58 on the other side. The damping element 11 'is connected to the slide part 8 via a rod-shaped force transmission element 54 on one side, the corresponding damping element 12' being attached to the frame 58.

Appropriate damping is provided by connecting the rod-shaped force transmission elements 54 and 55 with a slide part on one side and a damping element on the other side, both in the opening translatory process of the two slide parts and in the closing translational process of the two slide parts. which leads to a dampening opening and closing of the respective door.

During the translatory movement of the fastening part 19 into its lower end position, the latter moves to Fastening part overrun element 56 or onto the engaging element 21 in the form of the ferromagnetic element 14 or the second magnetic element 15, in order to bring about a magnetic frictional connection at least for a short time after the base element 3 has been withdrawn, so that after a very short time the fastening part 19 moves away from the fastening part overrun element 56 or detaches again from the engaging element 21 and / or the spreading movement is additionally magnetically damped at least over a very short translational travel path, this damping, of course, rapidly having no effect with progressive moving apart and the actual damping effect being exerted via the damping elements 11 and 12.

In order to ensure that the door lock mechanism 4 closes securely in the frame of the door frame after the fastening element 19 has been moved apart correspondingly from the engagement element 21 and thus is already in an end position, a force element 17 in the form of a spring element 18 exerts both on the engagement element 21 and a certain force is exerted on the fastening part 19 in order to ensure that in fact no dead spots of any kind within the door lock mechanism lead to the fact that no safe closing may have taken place, so that the door lock mechanism 4 via its corresponding force elements (not shown) therefor Ensure that the door in the door frame frame actually closes securely.

The foot surface spring element 51 acts on the foot surface element 3 or on the foot actuator mechanism 1 such that Releasing the foot panel element 3 - that is to say releasing it - moves it back to its starting position relatively quickly, so that after at least partial retraction of the foot panel element 3 in the direction of its starting position, the door opening mechanism 2 interacts mechanically with the door lock mechanism 4 independently of the foot panel element 3 (as described above) ,

Depending on the application and thus in particular on the forceful design of the door lock mechanism 4, a translational position of the engaging element 21 is to be set via a rotating movement on a thread of a rod (not shown) whether and when and thus how quickly the fastening part 19 should be released magnetically - after pulling back the base element 3.

In addition, a certain translational playability of the engaging element 21 is realized in that a rod (not shown) which is fastened to the base element 16 has a certain translational play. This can be achieved, for example, by a corresponding groove guide on the rod. This translational play of play thus allows a rod 33 of the door locking mechanism 24 to be released, so to speak, when a footwheel element 75 does not touch the rod 33 and is therefore not jammed and thus the rod 33 is translationally movable between a locking position Pos. 1 and a non-locking position item 2 by means of magnetic interaction. In position 2 there is a door locking magnet element 25 directly on a door frame magnetic element 27 or a magnetic door frame element 28 or a magnetic door locking element 26 lies directly on the door frame magnetic element 27. In position 1, the door locking magnetic element 25 or a magnetic door locking element 26 is drawn into the door by means of a locking magnet element 31 or 32, so that the rod 33 moves translationally in front of the gear wheel run-up element 75, so that the door lock mechanism 4 remains open due to the interactions described above within the door opening mechanism 2.

When the door falls into a door frame (not shown) of a door frame, the magnetic interaction forces between the elements 25, 26 and 27, 28 are greater than between 25, 26 and 31, 32. For this purpose, a certain spacing between 31.32 and 25.26 is often required by means of spacer element 72. The greater forces pull 25, 26 in position 2 and thus remove the rod 33 from the overlying gear wheel element 75, as a result of which the door lock mechanism 4 closes.
