(13) The invention will be described hereinbelow with reference to a hinge 1 for a swing door, in particular a glass swing door. FIG. 1 shows a schematic illustration of the hinge 1. The hinge 1 has a first hinge part 2 and a second hinge part 3. The first hinge part 2 is designed for receiving the swing door. In order for it to be possible to retain a door leaf of the swing door, the first hinge part 2 has a clamping device. The clamping device comprises a first clamping unit 4 and a second clamping unit 5. A first elastic plastics-material protector 6 is arranged on an inner surface of the first clamping unit 4. Furthermore, a second elastic plastics-material protector 7 is arranged on an inner surface of the second clamping unit 5. The door leaf is retained with clamping action between the first clamping unit 4 and the second clamping unit 5. For this purpose, use is made, in addition, of clamping screws (not illustrated).

(14) The second hinge part 3 is designed in the form of a hinge part which can be installed on a wall of a house or building or on a door frame. It has an installation unit 13, which can be fastened on the wall or the door frame by means of screws (not illustrated).

(15) Furthermore, the second hinge part 3 has a first pin holder 8 and a second pin holder 9, between which an accommodating sleeve 10 of the first hinge part 2 is arranged. The accommodating sleeve 10 encloses a pin body 11, which has a hinge-pin element 12 (cf. FIG. 2). A first end of the hinge-pin element 12 is arranged on the first pin holder 8. More precisely, the first end of the hinge-pin element 12 is arranged in the first pin holder 8. A second end of the hinge-pin element 12 is arranged on the second pin holder 9. Once again more precisely, the second end of the hinge-pin element 12 is arranged in the second pin holder 9. Crosspieces 14 of the first hinge part 2 project beyond the first pin holder 8 and the second pin holder 9 (cf. FIG. 1).

(16) The first hinge part 2 has a carrying body 15, which is illustrated schematically in FIG. 2. The carrying body 15 has formed in it a piston-unit holder 16 (cf. FIG. 3), in which a piston unit 17 is arranged in a displaceable manner. The piston unit 17 has a first piston-unit end 18 and a second piston-unit end 19. A latching body 20 is arranged at the first piston-unit end 18 (cf., in particular, FIGS. 4, 8 and 9), said latching body, in a latching position of the hinge 1, being arranged in a latching recess 26. The latching recess 26 is arranged on the pin body 11. A piston opening 21 is arranged at the second piston-unit end 19. A piston-spring element 22 in the form of a helical spring is arranged in the piston opening 21. The piston-spring element 22 has a first spring-element end 23 supported on the piston unit 17 at the end of the piston opening 21. A second spring-element end 24 is supported on a piston-adjusting unit 25. The piston-adjusting unit 25 is designed in the form of a screw which has an external thread and is arranged in a mating thread of the carrying body 15. Movement of the piston-adjusting unit 25 in the direction of the latching body 20 and movement of the piston-adjusting unit 25 in the direction counter to the latching body 20 makes it possible to adjust the force by which the latching body 20 is pushed into the latching recess 26. The force can be suitably adjusted, in particular, in dependence on the weight of the swing door such that the swing door is reliably retained in the latching position. Undesired release of the swing door from the latching position (for example by a gust of wind) is thus largely prevented, or at least made very difficult.

(17) The piston unit 17 has a longitudinal axis. First of all the latching body 20, then a first arresting unit 27, then a second arresting unit 28, then a third arresting unit 29 and then grooves are arranged along the longitudinal axis of the piston unit 17, as seen from the first piston-unit end 18 in the direction of the second piston-unit end 19 (cf. in particular, FIGS. 2 through 9). The grooves comprise a first groove 30A and a second groove 30B.

(18) As can be seen, in particular, from FIG. 9, the first arresting unit 27, the second arresting unit 28 and the third arresting unit 29 are arranged on an outer surface of the piston unit 17. The first arresting unit 27, the second arresting unit 28 and the third arresting unit 29 are designed in the form of a ring and are split.

(19) A first separating element 31 is arranged between the first arresting unit 27 and the second arresting unit 28. Furthermore, a second separating element 32 is arranged between the second arresting unit 28 and the third arresting unit 29. Both the first separating element 31 and the second separating element 32 are designed in the form of rings.

(20) The first separating element 31 has a first side, which is directed toward the first arresting unit 27. Furthermore, the first separating element 31 has a second side, which is directed toward the second arresting unit 28. A first abutment surface 33A is arranged on the first side of the first separating element 31. The first abutment surface 33A is arranged on a second abutment surface 34A of the first arresting unit 27. A third abutment surface 35A of a second side of the first separating element 31 butts against a fourth abutment surface 36A of the second arresting unit 28.

(21) The same applies to the second separating element 32. The second separating element 32 has a first side, which is directed toward the second arresting unit 28. A first abutment surface 33B on the first side of the second separating element 32 butts against a second abutment surface 34B of the second arresting unit 28. Moreover, the second separating element 32 has a second side, which is directed toward the third arresting unit 29. A third abutment surface 35B on the second side of the second separating element 32 butts against a fourth abutment surface 36B of the third arresting unit 29.

(22) The abutting abutment surfaces are designed to complement one another in each case. In particular, provision is made for the aforementioned abutment surfaces to be designed with a radius. In addition, or as an alternative, provision is made for the aforementioned abutment surfaces to be designed in the form of cones.

(23) At the first piston-unit end 18, a sleeve 37 is arranged in a displaceable manner on the piston unit 17, in the region of the latching body 20. The sleeve 37 has a first sleeve end 38 and a second sleeve end 39. The first sleeve end 38 is operatively connected to the first arresting unit 27. The second sleeve end 39 is operatively connected to the pin body 11. The first sleeve end 38 has an abutment surface 54, which is oriented in the direction of the first arresting unit 27. This abutment surface 54 butts against an abutment surface 55 of the first arresting unit 27. The abutment surfaces 54 and 55 are designed to complement one another. They may be designed with a radius and/or in the form of cones.

(24) As already mentioned above, the first groove 30A and the second groove 30B are arranged on the outer surface of the piston unit 17. As can be seen, in particular, from FIGS. 2 and 9, the first groove 30A and the second groove 30B are arranged diametrically opposite one another on the outer surface of the piston unit 17. The first groove 30A is followed by an essentially planar first pre-switching surface 46A, which extends from the first groove 30A to the third arresting unit 29. The second groove 30B is followed by an essentially planar second pre-switching surface 46B, which extends from the second groove 30B to the third arresting unit 29.

(25) The first groove 30A has arranged in it a first pressure-exerting unit 40, on which is arranged, in turn, a first elastic intermediate element 41. Moreover, a first adjusting unit 42 is arranged on the first elastic intermediate element 41 (cf., in particular, FIGS. 2, 3 and 6). The first adjusting unit 42 is designed in the form of a screw and is arranged in a thread in the carrying body 15. The first pressure-exerting unit 40 is of cylindrical design and, in addition, is formed from stainless steel. The first elastic intermediate element 41 is formed from an elastic plastics material. The elasticity of the first elastic intermediate element 41 is selected such that, on the one hand, it is possible to achieve a slight movement of the first pressure-exerting unit 40 relative to the piston unit 17. On the other hand, the elasticity is selected such that the piston unit 17 is reliably retained in the piston-unit holder 16. The first adjusting unit 42 makes it possible to adjust a force by which the first pressure-exerting unit 40 is arranged in the first groove 30A. This makes it possible to adjust the intensity of the braking action and thus the braking force during movement of the swing door.

(26) The second groove 30B has arranged in it a second pressure-exerting unit 43, on which is arranged, in turn, a second elastic intermediate element 44. Moreover, a second adjusting unit 45 is arranged on the second elastic intermediate element 44 (cf., in particular, FIGS. 2, 3 and 6). The second adjusting unit 45 is designed in the form of a screw and is arranged in a thread in the carrying body 15. The second pressure-exerting unit 43 is likewise of cylindrical design and, in addition, is likewise formed from stainless steel. The second elastic intermediate element 44 is formed from an elastic plastics material. The elasticity of the second elastic intermediate element 44 is selected such that, on the one hand, it is possible to achieve a slight movement of the second pressure-exerting unit 43 relative to the piston unit 17. On the other hand, the elasticity is selected such that the piston unit 17 is reliably retained in the piston-unit holder 16. The second adjusting unit 45 makes it possible to adjust a force by which the second pressure-exerting unit 44 is arranged in the second groove 30B. This makes it possible to adjust the intensity of the braking action and thus the braking force during movement of the swing door.

(27) As can be seen, in particular, from FIG. 9, the latching body 20 has a first end and a second end. Furthermore, the latching body 20 is provided with an opening 48, which extends from the first end to the second end. A pin element 47 is arranged in the opening 48. The pin element 47 projects both out of the first end and out of the second end. The latching body 20 is arranged on the piston unit 17 by means of the pin element 47.

(28) FIG. 10 shows a schematic illustration of the pin body 11. Furthermore, FIG. 11 shows a schematic side view of the pin body 11. As already explained above, the pin body 11 has the hinge-pin element 12, which extends from the pin body 11. A central crosspiece 51, on which the latching recess 26 is formed, is arranged between a first ring element 49 and a second ring element 50. The pin body 11 has, on its central crosspiece 51, a first control surface 52, which is adjacent to the latching recess 26. Also arranged on the central crosspiece 51 is a second control surface 53, which is likewise adjacent to the latching recess 26. The first control surface 52 and the second control surface 53 are arranged opposite one another on the central crosspiece 51 of the pin body 11 such that the latching recess 26 is arranged between the first control surface 52 and the second control surface 53. Both the first control surface 52 and the second control surface 53 are spaced apart further in the radial direction from the longitudinal axis of the pin body 11 than a minimum distance between the latching recess 26 and the longitudinal axis of the pin body 11.

(29) The hinge 1 has two active units. In the case of the embodiment illustrated in the figures, the first active unit comprises both the arresting units 27 to 29 and the sleeve 37. During movement of the swing door, for example, from an open position into a closed position, the sleeve 37, in the region adjacent to the latching position, and/or when the latching position is reached, is displaced along the longitudinal axis of the piston unit 17 in a direction away from the latching recess 26. In other words, the sleeve 37 is displaced in the direction of the first arresting unit 27. On account of the interaction of the sleeve 37, of the arresting units 27 to 29 and of the separating elements 31 and 32, the arresting units 27 to 29 are moved in the radial direction away from the longitudinal axis of the piston unit 17, to be precise in the direction of the surface of the piston-unit holder 16. The arresting units 27 to 29 thus position themselves against the surface of the piston-unit holder 16. This achieves, in particular, two effects. On the one hand, the abutment and the interaction of the arresting units 27 to 29 with the surface of the piston-unit holder 16 achieves the situation where movement of the swing door, for example movement in the direction of a closed position, is braked. On the other hand, the closed position of the swing door is reliably retained.

(30) The second active unit is formed by the aforementioned pressure-exerting units 40 and 43, by the elastic intermediate elements 41 and 44 and by the adjusting units 42 and 45. Said second active unit likewise serves for braking movement of the swing door and basically enhances the braking action of the first active unit.

(31) The features of the invention which are disclosed in the present description, in the drawings and in the claims may be essential both individually and in any desired combinations for the purpose of realizing the various embodiments of the invention.
