DETAILED DESCRIPTION

(9) FIG. 1 illustrates a schematic partial illustration of an arrangement 10 to which a sliding element 11, a stationary element 12 as well as a stop position damping device 13 belongs. According to the embodiment the stop position damping device 13 has a structural unit 14 that is attached to the sliding element 11. An activating part 15 is non-moveably attached to the stationary element 12. In modification of the illustrated embodiment, the structural unit 14 could also be attached to the stationary element 12 and the activating part 15 to the sliding element 11.

(10) At the sliding element 11 regularly a groove-like receiving space 16 is present that is open in a height direction H to the stationary element 12. This receiving space 16 is sufficiently large in standard doors or standard windows for accommodating the structural unit 14. The activating part 15 can be attached in a fixing groove 17 that is open in height direction toward the sliding element 11. At least a portion of the activating part 15 may extend out of the fixing groove 17 toward the sliding element 11 in the installation position.

(11) The sliding element 11 is slidably supported relative to the stationary element 11 in a sliding direction R. The sliding element 11 can be a wing of a door or a window, for example. In FIGS. 1 and 2 a closing position I of the sliding element 11 in relation to the stationary element 12 is illustrated respectively.

(12) A Cartesian coordinate system that is stationary relative to the stationary element 12 is defined by the sliding direction R, a transverse direction Q and a height direction H. The height direction H may be oriented substantially vertically. In the embodiment the sliding direction R extends in a horizontal direction. Depending on the installation position of the stationary element 12, a different orientation of the Cartesian coordinate system H, Q, R relative to the vertical or horizontal can occur.

(13) FIGS. 2 to 7 and 9 schematically illustrate an embodiment of the stop position damping device 13. A basic carrier 21 belongs to the structural unit 14 at which a damping cylinder supporting arrangement 23 is pivotably mounted around a first pivot axis S1 by means of a first pivot bearing 22. The first pivot axis S1 extends perpendicular to the sliding direction R and perpendicular to the height direction H in transverse direction Q. The first pivot bearing 22 is present at one end of the damping cylinder supporting arrangement 23. Starting from this first pivot bearing 22, the damping cylinder supporting arrangement 23 extends in a length direction L toward an opposite free end 24. In the embodiment the damping cylinder supporting arrangement 23 can be moved only in one single degree of freedom relative to the base carrier 21, that is executing a pivot movement around the first pivot axis S1. Preferably, additional guides between the base carrier 21 and the damping cylinder supporting arrangement 23 are not present. The base carrier 21 is non-moveably attached at the sliding element 11 according to the embodiment. The length direction L is stationary relative to the damping cylinder supporting arrangement 23 and can be oriented parallel or inclined with regard to the sliding direction R depending on the pivot position around the first pivot axis S1.

(14) At the free end 24 a biasing element 25 is present that creates a biasing force between the base carrier 21 and the damping cylinder supporting arrangement 23 and thus a torque M around the first pivot axis S1. The biasing element 25 can be formed by one or more elastically deformable bodies, for example. In the embodiment, the biasing element 25 is formed by a helical spring. According to the example, the damping cylinder supporting arrangement 23 has an end part 26 at its free end 24 that contains a receiving hole that is open toward the base carrier 21 and for example toward a base clearance 27 of the base carrier 21, into which the biasing element 25 extends partly. The biasing element 25 is supported with its respective other end at the base carrier 21 and according to the example at the base plate 27.

(15) In the present embodiment the base plate 27 extends from the free end 24 at least to the first pivot bearing 22. At the end of the base plate 27 that is arranged adjacent to the first pivot bearing 22 a fixing part 32 can be provided that extends transverse from the base plate 27 in a direction away from the first pivot bearing 22 and is configured for fixing, for example screwing, of the base carrier 21 at the sliding element 11.

(16) For defining the first pivot bearing 22, the base carrier 22 comprises a bearing body 28 that is attached at the base plate 27 in the present embodiment. The bearing body 28 supports the first pivot bearing 22 or defines a portion of the first pivot bearing 22. The bearing body 28 defines a height distance z between the base plate 27 and the first pivot axis S1 in height direction. This height distance z is unchangeably and constantly predefined in the preferred embodiment according to the FIGS. 1-7 and 9. In an alternative embodiment according to FIG. 8, the height distance z can be adapted to the constructive conditions at the assembly. In doing so, a respective adjustment device 29 can be present. An adjustment screw may belong to the adjustment device 29, for example, by means of which the position of a pivot bearing part 31 that defines the first pivot axis S1 may be adjusted in height direction H relative to the bearing body 28 or the base plate respectively. During operation the height distance z is unchangeable also in this alternative embodiment according to FIG. 8.

(17) A damping cylinder 35 belongs to the stop position damping device 13. The damping cylinder 35 extends in length direction L from a first end 36 to a second end 37. The distance between the first end 36 and the second end 37 is changeable. The first end is defined by a free end of the piston rod 38, the opposite end of which is connected with a piston 39. The piston 39, together with the piston rod 38, is slidably arranged in a cylinder housing 40 of the damping cylinder 35 in length direction L. In the embodiment the piston 39 limits a working area inside the cylinder housing 40 that may be implemented as gas pressure space 41, in which a compressible gas is present. The damping cylinder 35 thus forms a gas spring or gas damping device respectively, so to speak. Other force generating means may be provided alternatively or additionally in the working area, such as a mechanical spring device.

(18) The cylinder housing 40 is non-moveably fixed at and relative to the damping cylinder supporting arrangement 23. During a pivot movement of the damping cylinder supporting arrangement 23 around the first pivot axis S1, the damping cylinder 35 also pivots around the first pivot axis S1.

(19) At the first end 36, that is formed at the free end of the piston rod 38, a catch part 45 is arranged. The catch part 45 is pivotably mounted at the piston rod 48 around a second pivot axis S2 by means of a second pivot bearing 46. The second pivot axis S2 extends parallel to the first pivot axis S1 in transverse direction Q. The catch part 45 has a first catch part projection 47 and a second catch part projection 48. The two catch part projections 47, 48 are arranged with distance to each other in length direction L and limit a catch part gap 49 in between. Thus, the catch part 45 has with view in transverse direction Q mainly a U-shaped section in the region of the two catch part projections 47, 48. The second catch part projection 48, that is arranged between the first catch part projection 47 and the cylinder housing 40, extends less far in direction toward the activating part 15 compared with the first catch part projection 47. A reference plane that is spanned by the transverse direction Q and the length direction L and that touches the outermost end of the first catch part projection 47 is neither touched nor intersected by the second catch part projection 48.

(20) According to the example a plane that contains the second pivot axis S2 and that is oriented perpendicular to the length direction L intersects the first catch part projection 47 or has a smaller distance to the first catch part projection 47 as to the second catch part projection 48. The second catch part projection 48 is arranged closer to the cylinder housing 40 compared with the first catch part projection 47.

(21) At the catch part 45 a guide element 50 is provided and according to the example a guide projection 51. The guide projection 51 extends in transverse direction Q away from the catch part 45 and engages into a guide groove 52 at the damping cylinder supporting arrangement 23.

(22) The guide groove 52 extends along a first groove section 52a in length direction L. A second groove section 52b that adjoins the first groove section 52a, extends obliquely or perpendicularly to the first groove section 52a and extends according to the example in parallel or under an acute angle relative to the height direction H. The second groove section 52b forms a portion of the guide groove 52 that is arranged adjacent to the cylinder housing 40. From this second groove section 52b the first groove section 52a extends in direction towards the free end 24 of the damping cylinder supporting arrangement 23.

(23) The guide groove 52 is limited by a lower groove flank 53 and on the opposite side by an upper groove flank 54. The upper groove flank 54 is arranged at a larger distance from the base carrier 21 and particularly the base plate 27 or closer at the activating part 15 in the first groove section 52a compared with the lower groove flank 53. In the second groove section 52b the upper groove flank 52 is arranged closer to the first pivot axis S1 or farther away from the second pivot axis S2 as the lower nut flank 53. The lower groove flank 53 extends under an acute angle relative to a plane that is oriented perpendicular to the length direction L and curves in a transition section from the first groove section 52a to the second groove section 52b about an angle that is larger than 90 degrees. In doing so, a kind of undercut extension of the first groove flank 53 is formed in the second groove section 52b that is produced from by an extension component perpendicular to the length direction L and an extension component in length direction L away from the free end 24 with view from the end of the groove in direction toward the first groove section 52a.

(24) In the embodiment the guide projection 51 has a cross-section deviant from a circu-lar form and is for example elliptic. The guide projection 51 thus has a first cross-section dimension that is smaller than a second cross-section dimension measured perpendicular to the first cross-section dimension. The groove width of the first groove section 52a is at least as large as the smaller first cross-section dimension of the guide projection 51 and smaller than the second cross-section dimension of the guide projection 51. The second groove section 52b is at least as large as the second cross-section dimension of the guide projection 51. The groove is measured transverse to the extension direction of the guide groove 52 respectively, that is in length direction in the second groove section 52b and in a plane perpendicular to the length direction L in the first groove section 52a.

(25) With reference to the FIGS. 2-7 the function of the stop position damping device 13 is explained below.

(26) Provided a correct assembly, the damping cylinder 35 is brought into a tensioned position II, as illustrated by way of example in FIG. 7. In doing so, the piston rod 38 is inserted and the guide projection 51 is present in the second groove section 52b. In the tensioned position II the catch part 45 has a position, in which the activating part 15 can be moved without collision between the two catch part projections 47, 48 in the catch part gap 49. The catch part 45 is kept in the tensioned position II, because in the gas pressure space 41 a force is applied onto the piston 39 that urges the piston rod 38 in direction towards the extended position. Because of the force that acts on the piston rod 38 in the tensioned po-sition II, the guide projection 51 is urged against the lower groove flank 53. The lower groove flank 53 forms a kind of undercut. In doing so, the catch part 45 remains in its ten-sioned position as long as it is not moved out of the tensioned position by means of the activating part 45.

(27) FIG. 3 shows a situation after assembly in which the activating part 15 was erroneously not brought into the tensioned position II. The second catch part projection 48 is in a pivot position around the second pivot axis S2, in which the activating part 15 cannot move past the second catch part projection 48 into the catch part gap 49 without collision. A pivot movement of the catch part 45 around the second pivot axis S2 is impossible, be-cause the first guide projection 51 is outside the tensioned position II in the first groove section 52a and blocks pivoting of the catch part 45 around the second pivot axis S2. Start-ing from this erroneous assembly, if the sliding element is moved in sliding direction R in direction toward the closing position I (according to the first arrow P1 in FIG. 3) a colli-sion between the activating part 15 and the catch part 45 and, according to the example, the second catch part projection 48 occurs. This situation is illustrated in FIG. 4. Because of the pivot mobility of the damping cylinder supporting arrangement 23 around the first pivot axis S1, the damping cylinder supporting arrangement 23 is pivoted against the force of the biasing element 25 away from the activating part 15 towards the base carrier 21 or the base plate 27 respectively upon contact between the activating part 15 and the catch part 45, such that the activating part 15 can pass into the catch part gap 49. A damage of the catch part 45 is avoided.

(28) Out off the tensioned position II of the catch part 45 the activating part 15 engages between the two catch part projections 47, 48 into the catch part gap after error-free assembly or after error remedy as described above, which is illustrated exemplarily in FIG. 5. During a movement of the sliding element 12 together with the structural unit 14 from the closing position of the sliding element 11 away (in direction of an error P2 parallel to the sliding direction R in FIG. 5) the activating part 15 is in contact with the second catch part projection 48 and pushes the piston rod 48 into the cylinder housing 40. In doing so, a force builds up inside the damping cylinder 35 or in the gas pressure space 41 respectively that urges the piston rod 48 in its extended position.

(29) During this retracting movement of the piston rod 38 the guiding projection 51 moves initially in length direction L in the first groove section 52a and transverse to the length direction L as soon as it reaches the second groove section 52b and the catch part 45 executes a pivot movement around the second pivot axis S2 (FIG. 6). The second catch part projection 48 opens the catch part gap 49, such that the activating part 15 is released from the catch part gap 49 as soon as the catch part 45 was pivoted around the second pivot axis S2 in its tensioned position II. In this tensioned position the sliding element 11 can be moved in the direction of the second arrow P2 arbitrarily far away from the closing position in an open position (FIG. 7).

(30) As soon as the activating part 15 was moved out of the catch part gap 49 it moves relative to the structural unit 14 without contact. It has to be noted here, that during a movement of the sliding element 11 in sliding direction R only a contact between the activating part 15 and the catch part 45 may occur. Other contact locations, particularly frictional bearing locations or roller bearing locations, between the structural unit 14 and the activating part 15 or the element 11, 12 at which the activating part 15 is mounted, are not present.

(31) If the sliding element 11 is moved back in direction of the first arrow P1 in the closing position I, the conditions illustrated in FIGS. 5-7 are assumed in reverse sequence. At first, as illustrated in FIG. 6, the activating part 15 slides past the second catch part projection 48 until it abuts at the first catch part projection 47. As a consequence, a pivot movement of the catch part 45 around the second pivot axis S2 is initiated that causes the guide projection 51 to move out of the second groove section 52b in the first groove section 52a. Subsequently, the piston rod 38 is extended due to the pressure force present in the gas pressure space 41. During this extension movement, the second catch part projection 48 is supported at the activating part 15 and moves the sliding element 11 in a con-trolled manner in the closing position, as it is shown in FIG. 2. In this position, the sliding element 11 is additionally lowered in height direction H, which causes the oblique position of the length direction L with regard to the sliding direction R.

(32) The invention refers to a stop position damping device 13 for a sliding element 11 that is slidably ranged in a sliding direction R relative to a stationary element 12. The stop position damping device 13 comprises a structural unit 14 and an activating part 15 that are connected to one of the two elements 11, 12 respectively. The structural unit 14 has a base carrier 21 at which a damping cylinder supporting arrangement 23 is pivotably mounted with one and around a first pivot axis S1. At the opposite free end 24, the damping cylinder supporting arrangement 23 is supported without guidance at the base carrier 21 by means of a biasing element 25, wherein the biasing element 25 creates a torque around the first pivot axis S1. In an area that is closer to the free end 24 as to the first pivot axis S1, a catch part 45 can move in a length direction L relative to the damping cylinder supporting arrangement 23. If an unintended collision occurs between the activating part 15 and the catch part 45 due to an erroneous assembly, the damping cylinder supporting arrangement 23 with the catch part 45 can pivot away from the activating part 15.
