DETAILED DESCRIPTION OF THE DRAWINGS
(12) Throughout the different Figures, same parts of the device 100 and of the system 110 are always identified with the same reference numerals, and therefore, normally they will be only described once.
(13) The FIGS. 1 and 3 show a device 100 in the sense of the disclosure, which is embodied for moving a door leaf 101 between an open position O and a close position S. For this purpose, the device 100 includes lever kinematics 10, which can be brought into operative connection with a guiding rail 20. Together the lever kinematics 10, a sliding member 21 and the guiding rail 20 form an inventive system 110.
(14) Within the scope of the inventive device 100 as well as the inventive system 110, the lever kinematics 10 includes a lever 11, which at a first section 12 is rotatably connected to the sliding member 21, which can be linearly movably accommodated in the guiding rail 20. In this exemplary embodiment, the lever kinematics 10 corresponds to the lever 11. Thus, the first section 12 of the lever 11 establishes a mechanical operative connection between the rest of the lever kinematics 10 and the guiding rail 20.
(15) Furthermore, the lever 11 includes a second section 13 for establishing a mechanical operative connection of the rest of the lever kinematics 10 to a drive 30. The drive 30 includes at least one energy recipient 32, such as e.g. a switch valve and/or an electric motor. The drive 30 can be embodied for assisting and/or for performing the movement of the door leaf 101 between the open position O and the close position S, for example as a mechanical or electrical door closer.
(16) Most of the time, the connector to an energy source 22, e.g. in the shape of a power supply unit, is provided stationarily on a casing 102. In order to allow for a connection for transmitting electric energy and/or data between a casing-sided energy source 22 and at least one drive-sided energy recipient 32, a transmission means 31 is provided. The transmission means 31 represents a part of the inventive device 100 and of the inventive system 110.
(17) In this case, the transmission means 31 needs to be laid between the casing-sided energy source 22 and the drive-sided energy recipient 32 over the guiding rail 20 and the lever kinematics 10.
(18) The transmission means 31 can include a loop-shaped section 33, which can be disposed in the guiding rail 20 in order to allow the transmission means 31 to follow, when moving the sliding member 21 along the guiding rail 20.
(19) At the transition between the lever kinematics 10 and the guiding rail 20, the transmission means 31 passes through the sliding member 21 and a connecting element 40 at the lever 11. In addition to the lever kinematics 10 and the transmission means 31, the connecting element 40 is a part of the inventive device 100.
(20) When the lever 11 moves in relation to the sliding member 21, the relative position of the connecting element 40 to the sliding member 21 changes. In order to allow for said movement, a functional reception 23, in particular circle segment shaped, is formed in the sliding member 21.
(21) FIG. 2 top row and FIG. 9 illustrate how an inventive system 110 with an inventive device 100 functions when mounting the device 100 to a DIN left-handed door leaf 101 on a pull side. Hereby, the door is closed in the left depiction of FIG. 2 top row and of FIG. 9. The lever 11 is parallel to the guiding rail 20. The connecting element 40 is in a first start position 1 with regard to the lever 11 and in a first end location within the functional reception 23. In the first start position 1, the connecting element 40 rests at a first abutment 60 of the lever 11 (see FIG. 8). As an alternative, in the first start position 1, the connecting element 40 can be located near the first abutment 60 of the lever 11. In the first end location, the connecting element 40 is near a first sidewall 25 of the functional reception 23.
(22) In the middle depiction of the top row of FIG. 2 and of FIG. 9, the door is opened by about 90°. The lever 11 is disposed angled to the guiding rail 20. The connecting element 40 remained in the first start position 1 with regard to the lever 11. However, the connecting element 40 is located in a second end location within the functional reception 23. Hereby, the connecting element 40 is located near a second sidewall 26 of the functional reception.
(23) In the right depiction of the top row of FIG. 2 and of FIG. 9, the door is completely opened. Again, the lever 11 is disposed parallel to the guiding rail 20. On account of friction contact, the connecting element 40 has remained in the first start position 1 with regard to the lever 11. The connecting element 40 moved back to the first end location within the functional reception 23 and is located near the first sidewall 25.
(24) The lower row of FIG. 2 illustrates a conceptual experiment. Now, the device 100 is mounted to a DIN right-handed R door leaf, on the push side OUT. Unlike in the inventive device, the connecting element 40 is still located in the start position 1. With the door being closed, like illustrated in the left depiction of the lower row of FIG. 2, said arrangement is still possible. However, in case now the door is opened and the lever 11 is pivoted, as illustrated in the middle and right depiction of the lower row of FIG. 2, the lever 11 presses the immobile connecting element 40 of the conceptual experiment against the first sidewall 25 and breaks.
(25) The system 110 would have a different behaviour, if, in the left depiction of the lower row of FIG. 2, the connecting element 40 would be in a second start position 2 with regard to the lever 11, as inventively intended. This is illustrated in FIG. 12, as described in the following.
(26) In FIG. 12, the inventive device 100 and the inventive system 110 are mounted on a pull side of a DIN R door leaf 101. In the left depiction of FIG. 12, analogously to FIG. 9, the door is closed, in the middle depiction of FIG. 12 the door is opened by about 90° and in the right depiction of FIG. 12 by about 180°.
(27) In all depictions of FIG. 12, the connecting element 40 is located in the second start position 2. In the second start position 2, the connecting element 40 rests at a second abutment 61 of the lever 11 (see FIG. 8). As an alternative, the connecting element 40 is located in the second start position 2 near the second abutment 61. In the left depiction of FIG. 12, the lever 11 is located parallel to the guiding rail 20 and the connecting element 40 is located near the second sidewall 26. The connecting element 40 is located in the second end location. When the door is opened by about 90°, the lever 11 moves. Hereby, the connecting element 40 remains in the second start position. Moving the lever 11 causes the connecting element 40 to move as well until the connecting element 40 is located near the first sidewall 25.
(28) Now, the connecting element 40 is located in the first end location. As the connecting element 40 is located in the second start position and not in the first start position, moving the connecting element 40 is possible without breaking off. With a further opening movement, the angle decreases between the lever 11 and the guiding rail 20. In the right depiction of FIG. 12, the lever 11 is again located parallel to the guiding rail 20. The connecting element 40 moved back to the second end location within the functional reception 23 and is located near the second sidewall 26.
(29) Changing the start positions 1, 2 according to the desired mounting type DIN R or DIN L corresponds to the inventive method.
(30) FIG. 10 shows the movement of the lever 11 when opening the door analogously to FIG. 9 for DIN L doors. In contrast to FIG. 9, the lever is disposed on the push side.
(31) FIG. 11 shows the movement of the lever 11 when opening the door analogously to FIG. 12 for DIN R doors. In contrast to FIG. 12, the lever is disposed on the pull side.
(32) Both the comparison of FIGS. 9 and 10 and the comparison of FIGS. 11 and 12 result in that the first end location with push side mounting is located closer to the first sidewall 25 than with pull side mounting. With push side mounting, the second end location is located closer to the second sidewall 26 than with pull side mounting. The abutments 60, 61 and the size of the functional reception 23 as well are dimensioned such as to prevent the connecting element 40 from breaking off with push side mounting.
(33) In the event the connecting element 40 can not only be disposed in the two start positions 1, 2, but moreover rotatably mobile supported at the lever 11, the following advantage results:
(34) When using the device 100 for the first time and the connecting element 40 is located at the incorrect start position 1, 2, which without rotary mobility of the connecting element 40 results in the connecting element 40 breaking off (see left lower depiction of the FIG. 2), the connecting element 40 moves to the correct start position 1, 2 without an installer intervening. For example, in the left lower depiction of FIG. 2, the connecting element 40 is located in the incorrect start position 1, which without rotary mobility of the connecting element 40 would result in the connecting element 40 breaking off (see middle lower depiction of FIG. 2). On account of the rotary mobility of the connecting element 40, the connecting element 40 is pressed against the first sidewall 25, while the lever 11 moves from the location of the left lower depiction in FIG. 2 to the location of the middle lower depiction of FIG. 2. However, on account of the rotary mobility of the connecting element 40, the connecting element 40 does not break off, unlike illustrated in FIG. 2, but moves to the second start position 2. When closing the door, the device reaches the position according to FIG. 12 without the installer intervening, left hand depiction. During subsequent operation, the connecting element 40 remains in the start position 2. Now as illustrated in FIG. 12, the connecting element 40 can move. Said procedure corresponds to a particularly preferred inventive method.
(35) Furthermore, based on the rotatable support of the connecting element 40 at the lever 11, when opening the door, it is possible for the connecting element 40 not to remain in the respective start position 1, 2, but in particular to slightly turn. Hereby allowing for compensating fault tolerances.
(36) In other words: As obvious in FIG. 2, problems can arise when mounting the device 100 to a DIN left-handed L or to a DIN right-handed R door leaf 101. Depending on the mounting type of the lever kinematics 10, the relative rotation between the sliding member 21 and the lever 11 amounts to about 30° on the pull side IN and to about 60° on the push side OUT. In case the lever kinematics 10 is disposed to a DIN left-handed L or to a DIN right-handed R door leaf 101, additionally, the relative direction of rotation reverses between the sliding member 21 and the lever 11. Consequently, the relative movement between the sliding member 21 and the lever 11 can amount to up to about 120° or more to up to 140°. Often a corresponding movement of the connecting element 40 within the sliding member 21 is not possible, based on the lacking construction space within the guiding rail 20 and thus of the sliding member 21. As shown at the bottom in the middle view in FIG. 2, within the existing functional reception 23 in the sliding member 21, the connecting element 40 can collide with the guiding rail 20 and even break off.
(37) Therefore, conventional devices require at least two lever kinematics 10 variants with the stationary connecting element 40, one for a DIN left-handed L door leaf 101 and one fora DIN right-handed R door leaf 101.
(38) The disclosure overcomes the above-mentioned disadvantages and provides a device 100, which can be embodied as shown in FIGS. 4 to 12. According to the disclosure, for this purpose it is provided for the connecting element 40 to be disposed in the first and in the second start positions 1, 2. The connecting element 40 is rotatably supported, in particular at least between two different start positions 1, 2, at a first section 12 of the lever 11, which for example can be in a range of maximum +/−50°, in particular maximum +/−40° with regard to the longitudinal extension axis of the lever 11, wherein said ranges can be marked by abutments 60, 61 in a guide 12a at the first section 12 of the lever 11.
(39) The rotatable support of the connecting element 40 at the lever 11 creates an additional degree of freedom for flexibly mounting the connecting element 40 to the lever 11. In this way, the connecting element 40 can be positioned at the lever 11 in different start positions 1, 2 in a simple and optional manner, depending on the desired mounting type. Moreover, when operating the device 100, the connecting element 40 does not necessarily have to remain in one of the start positions 1, 2. Rather, a slight rotation allows for compensating a fault.
(40) The respective mounting type can comprise mounting to a DIN left-handed L or a DIN right-handed R door leaf 101, on a pull side IN or on a push side OUT of the door leaf 101. Thus, the necessary turning of the sliding member 21 in relation to the lever 11 by at least 120° (respectively at least in a range of +/−60°) is possible. The connecting element 40 can be manually brought into the respective appropriate start position 1, 2 and/or the sliding member 21 can automatically turn it. Advantageously, the disclosure does not require any modifications at the sliding member 21 and/or in the guiding rail 20.
(41) The connecting element 40 can comprise a guiding element 42 and an adapter element 14. The guiding element 42 is reversibly releasably connected to the adapter element 14. According to an embodiment of the disclosure of FIG. 4, the adapter element 14 can be rotatably supported along a guide 12a at the first section 12 of the lever 11. According to another embodiment of the disclosure and the idea of FIG. 4, the adapter element 14 can include at least one sliding element 14a, which is rotatably accommodated at a guide 12a at the first section 12 of the lever 11.
(42) As illustrated in FIG. 2 and in FIG. 8, the connecting element 40 can be embodied with a plug-in guide 41 for the transmission means 31. For example, the plug-in guide 41 can serve for deflecting the transmission means 31 at least once, preferably twice, in particular by 90° and/or for deflecting at least once, preferably twice, in particular by 45°. Deflecting and/or folding back the transmission means 31 at least once, preferably twice (compare FIG. 7) can allow for laying the transmission means 31 along a branch-type arrangement between the lever 11 and the guiding rail 20, which moreover can have different construction heights. Moreover, the plug-in guide 41 can effect strain relief at the transmission means 31.
(43) As indicated in FIG. 7, at least section-wise the inventive transmission means 31 can be configured as a flat cable, flat ribbon cable or a flexible printed circuit board. Basically however, a round cable is conceivable as well as the transmission means 31.
(44) As shown in the middle of FIG. 7, uniquely featuring the transmission means 31, the transmission means 31 can have at least one, preferably two deflection points U1, U2, in particular by 90°, and/or at least one, preferably two fold back points T1, T2, in particular by 45°, which can be based on the reception in the plug-in guide 41 at the connecting element 40. On account of the plug-in guide 41, the transmission means 31 can be affixed to the connecting element 40 without additional attachment means as well as under strain relief.
(45) As furthermore shown in the FIGS. 5 to 7, according to an advantage of the disclosure, a storage unit 15 can be provided in or at the lever 11 for accommodating a length of the transmission means 31, in order to allow for adjusting n the transmission means 31 when turning the connecting element 40 in relation to the lever 11 (compare enlarged view at the bottom right in FIG. 7).
(46) As indicated in the different views of FIG. 5, the length of the transmission means 31, which the storage unit 15 can accommodate for adjusting n the transmission means 31, can be folded in a loop shape, respectively U shape, meander shape or accordion shape.
(47) Likewise, the storage unit 15 can be realized differently, as diagrammatically shown in FIG. 6. As shown above in FIG. 6, the storage unit 15 can be formed in the shape of a circle segment shaped groove N1 in the first section 12 of the lever 11, which in particular extends around an axis of rotation D of the lever 11 with regard to the guiding rail 20.
(48) As shown in the middle of FIG. 6, the storage unit 15 can be formed in the shape of a linear groove N2, for example, which extends along an extension axis of the lever 11. As shown at the bottom in FIG. 6, the storage unit 15 can be formed in the shape of a reception N3 at a separate add-on piece N, in particular rotationally mobile supported at the lever 11, in particular for the first section 12 of the lever 11.
(49) Furthermore, as shown in FIG. 5, the lever 11 can include a guiding groove 16, potentially with a groove cover 17 for the transmission means 31, in order to accommodate the transmission means 31 in a protected manner in the lever 11. Furthermore, it is conceivable for the lever 11 to include a metal core 11a and a plastic material housing 18, wherein in particular the guiding groove 16 can be formed between the metal core 11a and the plastic material housing 18. In this case, the groove cover 17 can correspond to the plastic material housing 18.
(50) As already mentioned above in conjunction with the FIGS. 1 and 3, a system 110 for moving a door leaf 101 between an open position O and a close position S with regard to the door opening 104 in a wall 103 is a further aspect of the disclosure. In this case, the system 110 includes a device 100, which can be embodied as described above, and a guiding rail 20, in which a sliding member 21 is movably accommodated, wherein the sliding member 21 is rotatably connected to the first section 12 of the lever 11.
(51) As shown in FIG. 3, within the scope of the inventive system 110, the sliding member 21 can include a functional reception 23 for the connecting element 40, in order to allow for a displacement of the connecting element 40 during a rotary movement d of the lever 11 in relation to the sliding member 21 (the rotary movement d of the lever 11 is indicated in the FIG. 7). Furthermore, the sliding member 21 can include a rotary reception 24 for a rotary head A of the lever 11, in order to allow for a rotary movement d of the lever 11 in relation to the sliding member 21. In this case, it is conceivable for the rotary reception 24 to be formed continuously with the functional reception 23. Moreover, it is conceivable for the transmission means 31 to pass centrally through a rotary reception 24 located at the sliding member 21 for a rotary head A of the lever 11.
(52) Furthermore, as shown in FIG. 3, a guiding unit 50 can be provided for the transmission means 31 at the sliding member 21. For example, the guiding unit 50 can be provided following the functional reception 23 for the connecting element 40 and following the rotary reception 24 for a rotary head A of the lever 11, prior to introducing the transmission means 31 into the guiding rail 20. The guiding unit 50 can be formed to prevent the transmission means 31 from moving to the top or to the bottom out of the sliding member 21, in the view of FIG. 3. For this purpose, at the top and at the bottom, limitation hooks, which are just diagrammatically indicated in the FIGS. 2 and 3, can be provided in the guiding unit 50.
(53) FIG. 8 individually illustrates a part of the lever 11, in particular of the plastic material housing 18, the adapter element 14 and the guiding element 42. The combined view of the lever 11 and of the adapter element 14 result in showing the projections 64 of the sliding elements 14a engage behind the guide 12a of the lever 11. Hereby, the connecting element 40 is captively supported at the lever 11. Only one projection 64 is depicted of all the projections 64 in FIG. 8. Additionally, a further projection 66 engages behind a further guide 12b of the lever 11.
(54) The adapter element 14 comprises abutment surfaces 62, from which only one abutment surface 62 is depicted in FIG. 8. The adapter element 14 with respectively one of the abutment surfaces 62 can contact one of the abutments 60, 61 of the lever 11.
(55) The adapter element 14 comprises a mandrel 63. In the mounted condition, the hood-shaped guiding element 42 is fitted over the mandrel. With an attachment section 65, the guiding element 42 is attached to the adapter element 14. In particular, the guiding element 42 with the attachment section 65 is inserted or clipsed into the adapter element 14.
(56) The guiding element 42 comprises a plug-in guide 41. The guiding element 42 comprises a guiding surface 67. The transmission means 31 is fitted through the plug-in guide 41. The transmission means 31 is guided between the guiding surface 67 and the mandrel 63.
(57) The preceding description of the Figures describes the present disclosure exclusively on the basis of examples. Obviously, individual features of the embodiments, as long as they are technically reasonable, can be freely combined with each other without departing from the scope of the present disclosure.
