Definitions

  • the present invention relates to a door opener that enables a hinged door to be opened from both sides without using hands.
  • door handles that they have to be touched by hand for optimal operation.
  • a door handle is not usually provided for opening the door with your forearm. Even if there may be designs that have ergonomically shaped components for actuation with the forearm, the door handle must always be moved downwards and a pushing or pulling movement to open the door.
  • the WO 2012/152277 A1 shows a door opener with a lever arm for pushing or pulling in a direction perpendicular to the door. With a single movement, the lock latch can be drawn in and the door opened at the same time. However, the coupling of the lever arm and the lock follower is translated via a gear, which because of the Gears have a low wear resistance and do not offer good ergonomics because of the direct movement translation.
  • the invention relates to a door opener which has the following: a housing for attachment to a swing door, a piston which is mounted in the housing so that it can be displaced along a lock axis and rotated about this lock axis, a lever element which, at a first point in the housing, can be rotated about a first axis and at a second location relative to the piston rotatable about a second axis, the first and second axes being parallel and non-parallel to the lock axis, a mandrel having at least a portion with to cooperate with a square opening of a lock follower of the swing door Has a square profile, the piston being mounted on one end of the mandrel in a non-rotatable manner relative to the mandrel and displaceable along the lock axis, a link guide which is formed by a first element on the housing and a second element on the piston, the first or second element serving as a link track and the respective other element is designed as a sliding block, u
  • the mandrel comprises two mandrel components each having a shoulder and connectable to form the mandrel such that the square profile section is located in the square opening of the lock follower, the lock follower on either side of the mandrel components clamped and the mandrel is thus locked relative to the lock nut in a rotationally fixed manner on the lock nut.
  • a sliding element is provided at the end of the mandrel for such interaction with a recess that fits the sliding element precisely and is arranged parallel or helically to the lock axis on the piston such that a rotary movement of the piston about the lock axis is transmitted to the mandrel and that the recess slides on the sliding element.
  • the recess has at least one groove in the piston, with the sliding element having a rounded body made of metal, plastic or ceramic.
  • the lever element has a shaft at the first point, which is rotatably mounted on roller bearings or plain bearings in the housing, with the first axis being at a distance from the second axis and the lock axis of between 0.5 cm and 5 cm.
  • the lever member has a connector at the second location connecting the piston to the lever member, the housing having an aperture through which the connector extends and dimensioned such that the connector in the aperture is perpendicular to the second axis is movable.
  • the piston has a groove transverse to the lock axis and the connecting piece is slide-mounted in the groove in such a way that the piston can rotate relative to the connecting piece and about the lock axis, but relative translation between the piston and connecting piece parallel to the lock axis is blocked .
  • the second axis is at a maximum distance of 2 cm from the lock axis, in particular less than 1 cm, in every possible position of the lever element.
  • the lever element has an actuating area which is a distance from the section of the mandrel with the Square profile, which interacts with the square opening of the lock follower, has at least 5 cm, in particular at least 7 cm.
  • the lever element is designed and mounted in such a way that by pressing or pulling the actuating area at least partially parallel to the lock axis, the lever element rotates about the first point, the piston is displaced by the lever element at the second point along the lock axis and the mandrel is moved by means of the Link guide between housing and piston is rotated around the lock axis.
  • the link track has an area dimensioned in such a way that the sliding block can be moved in a starting position in both directions along the link track.
  • the mandrel is designed as a continuous square bolt, which is designed in such a way that it can be locked in the square opening of the lock follower, and the piston has a square hole, by means of which the piston is rotatably mounted on the square bolt and can be displaced along the lock axis.
  • the door opener has a locking mechanism that blocks the movement of at least one part from the following group: the lever element, the piston, the sliding block, the mandrel.
  • the door opener has a mechanical switch or an electronic unit with energy storage for activating and releasing the locking mechanism.
  • figure 1 shows an embodiment of the door opener 1 according to the invention attached to a stop door 3.
  • some components are duplicated, for example the lever elements 5, so that the stop door 3 can be opened from both sides.
  • the hinged door 3 has a latch 20 which is slidably mounted in the mortise lock 21 .
  • the door 3 opens forwards because it has a shoulder to rest on the door frame.
  • the door opener according to the invention can also be used on doors that can open in both directions.
  • caps 22 may be decorative and have "PUSH” and "PULL” printed or engraved.
  • the lever element can accordingly also only be pressed or pulled on the other side.
  • the lever elements 5 can be moved in both directions in order to retract the latch bolt. For example, it can be useful to pull on the lever element, although the door has to be pushed open. For example, to counter this, you place your elbow on the door and reach behind the lever element with your forearm or wrist to pull it towards you. The arm is now crossed between the lever element and the door leaf, the latch bolt is held back and the door can be opened in a controlled manner to the desired position.
  • figure 2 shows door opener 1 off figure 1 from the side when not actuated.
  • the lock latch 20 of the mortise lock 21, the lever elements 5 of the door opener 1, and the decorative caps 22 can also be seen here.
  • figure 3 shows the same parts, the door opener 1 being actuated here via the actuating area 18 of the lever 5, as can be seen from the levers 5 deflected about the first axis A 1 .
  • the storage of the lever elements 5 at a second point is covered here and is in the figures 6 and 8th apparent.
  • To open door 3, here in figure 3 either the right lever was pushed towards door 3, or the left lever was pulled away from door 3. Both levers 5 always move synchronously, no matter which side was pressed.
  • the latch bolt 20 is drawn into the mortise lock 21 first.
  • the lock latch 20 clears the way, the door leaf 3 is opened with the same push or pull movement by the user.
  • a lever element 5 can be U-shaped, with at least one, in particular both legs of the lever 5 being mounted at the first point S 1 , so that the lever 5 can be pivoted about the first axis A 1 .
  • the lever may have only one rod, so that it is mounted in the housing on only one side.
  • FIG 6 shows a sectional view of the door opener figure 2 .
  • the housing 2 is here firmly connected to the door 3, such as by a screw connection. This attachment takes place in such a way that a piston 4 pushed into the housing 2 can be displaced parallel to the lock axis As.
  • the lock axis As can be defined by the lock follower 7 of the door, which in turn can be rotated about the lock axis As.
  • the piston 4 can also be rotated within the housing 2 about this lock axis As.
  • the piston is cylindrical and slides in a cylindrical bore of the housing.
  • the second axis A 2 is defined in the piston 4 at a groove 17 incorporated therein, in which a connecting piece 16 connected to the lever element 5 is slide- and/or roller-mounted.
  • the connecting piece 16 (and thus the second axis A 2 ) can be displaced vertically relative to the groove 17 of the piston 4 and, on the other hand, can rotate about the second axis A 2 .
  • the actuation of the lever element 5 thus displaces the piston along the lock axis As.
  • the side opening 19 in the housing gives the connector 16 access to the piston.
  • the cap 22 shown this also has a recess in which the connecting piece 16 can move freely.
  • a telescopic curtain can be provided to close the gaps that form.
  • the lever 5 can also be pivoted at the first point S 1 via such a connecting piece or a pin, for example by means of a slide bearing or a roller bearing.
  • This camp can be seen here on a separate plate.
  • the plate can be regarded as belonging to the housing and in other embodiments the housing can of course also be in one piece, or the bearing of the first point S 1 of the lever 5 is provided on the housing.
  • a slotted guide which is implemented by the piston 4 and the housing 2, ensures that the piston 4 also rotates about the lock axis As when it is displaced as a result of the actuation of the lever 5.
  • a mandrel 6 is non-rotatably connected to the piston and is therefore rotated when the lever 5 is actuated.
  • the mandrel 6 is in operative connection with the lock follower 7 and its rotation therefore causes the latch bolt to be retracted.
  • the mandrel 6 is constructed in several parts.
  • the mandrel components 12 and 13 each have a shoulder and are to be connected from both sides of the end nut 7 .
  • the component 12 has a square section 8 by means of which it is pushed into the lock follower 7 .
  • the second component 13 is now pushed onto the first component, in particular firmly connected to it, e.g. by clamping or a thread.
  • a one-piece mandrel in particular a mandrel designed as a simple square, can also be used according to the invention.
  • the piston 4 is mounted on one end 9 of the mandrel 6 so that it can be displaced along the lock axis As.
  • the piston 6 has on the one hand a bore into which the relevant part of the mandrel 6 fits exactly, and on the other hand a recess 15 or groove (in particular on both sides) in which a sliding element 14 can move with a precise fit.
  • the sliding element 14 is rigidly connected to the mandrel 6 and protrudes laterally from it, so that the lever with which the mandrel is "taken along" by the piston is increased.
  • the bore in the piston is a square opening, in which a mandrel designed as a square can be inserted. The square profile can then ensure the form fit.
  • such a sliding element designed as a sliding block 11 can also comprise a rounded body made of metal (especially hardened), plastic or ceramic in order to further improve wear resistance.
  • these can be rings, tori or ellipsoids. The rounding can achieve the smallest possible friction surface.
  • the link path 10 runs partly in the circumferential direction (with reference to the cylindrical housing or piston), partly in the axial direction (with reference to the lock axis As). It can therefore in particular be a helical or helicoidal course. However, the link track can also take on individual curves, for example to improve ergonomics even further.
  • the link track can be moved from its starting position (as shown in figure 7 is shown) starting out more in the axial direction and not or only slightly progressing in the circumferential direction, which then increases. This can also apply to the area of the link track, in which the lock latch is almost completely drawn in and gives free rein to the door opening.
  • the link track can also be shaped in such a way that the rotation of the mandrel 6 is reduced in order to improve the "feel" when the door is opened.
  • each of the door opener 1 in the position of figure 3 represent, ie in a sectional view and a view from below (with the plate removed). It is important to mention that the exemplary embodiments shown in the figures are only ever provided for one direction of movement of the lever 5 (on the plane of the paper from right to left). This means that logically the lever 5 can only be pushed where the door has to be pushed open to open it, and can only be pulled there where the door also has to be pulled.
  • FIG. 1 Another embodiment, not shown, is arranged so that one can pull and push the lever on either side of the door to retract the latch.
  • This embodiment relates to the application mentioned above, in which you want to pull the lever and push the door open with your elbow, for example.
  • the mandrel should be long enough on both sides and it may, as in figure 6 eg is the case, have no paragraph 23, which blocks the piston.
  • all components of the door opener are identical for the front and the back of a door, so that one and the same door opener can be used for both sides.
  • a locking mechanism can be provided in or on the door opener, which (a) the lever element 5, (b) the piston, (c) the sliding block 11 and/or the mandrel 6 in its movement blocked.
  • the door 3 can be locked without a lock bolt of the mortise lock 21 having to be used.
  • the lock latch 20 is locked in its position in the end.
  • a switch for tilting or sliding that is accessible to the user and attached to the side of the housing (and protruding through a possibly present shell 22 by means of a corresponding hole in it) could be provided.
  • the switch is designed in such a way that it blocks the freedom of movement of the piston on the inside. So
  • a blocking element can engage in a corresponding groove in the piston, for example the opening 19, by means of the switch.
  • an electronic unit with an energy store e.g. rechargeable battery, in particular with a solar cell
  • the electronic unit can contain an adjustment motor which is controlled, for example, via a reading device for electronic keys ("badge").
  • the reading device can be integrated in particular in the lever element 5 or attached to the housing 2 or cover 22 .
