Definitions

  • the invention relates to a retraction device with a housing, in which a driver element can be guided between a stable parking position and an end position by means of two bearing elements along at least one first guide slot section and a second guide slot section enclosing an obtuse angle therewith, the driver element having a third bearing element which forms a swivel-and-slide joint with a driver element guide part that can be guided in the direction of the second guide link section and is loaded in the direction of the end position by means of a spring energy store, the third bearing element being seated in a guide hole of the driver element guide part.
  • the EP 2 466 047 A1 discloses a device in which the driver element is mounted with a pin in an elongated hole of a carriage and with two pins in a carrier plate. If an object of great inertia strikes, either the driver, which is designed as a wheel, can jump out of the depression in the driver element or the pins of the driver element jump out of the conductor tracks of the carrier plate.
  • the present invention is based on the object of developing a draw-in device that is operationally reliable with high inertia.
  • the entrainment element guide part has at least one stop for limiting the pivoting of the entrainment element which protrudes beyond the first bearing element on the side facing away from the second guide link section.
  • the swivel and slide joint has a thrust direction which includes an acute angle with the direction of the first guide slot section, the apex of said angle being on the side facing away from the second guide slot section with respect to the bearing pin.
  • Objects of great inertia are, for example, sliding doors of great mass, e.g. 50 kg - 80 kg, which are moved at high speed, e.g. 1 meter per second to 1.5 meters per second, into their closed end position, for example.
  • the load that suddenly occurs on the driver element is absorbed by the arrangement and the design of the swivel and slide joint in combination with the stop in the driver element guide part. Due to the design of the bearing points and their arrangement with respect to one another, the pull-in device is self-locking in the stable parking position.
  • the Figures 1 - 10 show a retraction device (10).
  • retraction devices (10) are used, for example, to pull sliding doors, drawers, etc. into this closed end position in a partial stroke of the closing stroke adjacent to the closed end position, for example.
  • a driver (5) is arranged on the sliding door, which, when the sliding door is closed, couples with a driver element (41) of the pull-in device (10).
  • the entrainment element (41) is here initially in the Figure 2 shown stable parking position (13), where it is inclined, for example, at a pivot angle ( ⁇ ) to the longitudinal direction (15).
  • the driver (5) releases the driver element (41) from this stable parking position (13) so that the retraction device (10) moves the sliding door in the closing direction (16) the end position promotes.
  • the entrainment element (41) is then in the Figure 1 illustrated end position (14).
  • the driver (5) pulls the driver element (41) out of the end position (14), cf. Figure 1 , in the opening direction (17) in the stable parking position (13), cf. Figure 2 .
  • the driver element (41) is locked in a non-positive and / or form-fitting manner.
  • the retraction device (10) can also be used in a partial stroke of the entire opening stroke adjacent to the open position.
  • the draw-in device (10) comprises a housing (21) in which the entrainment element (41), a entrainment element guide part (61) coupled to it and a spring energy store (81) forming a drive element (81) are arranged.
  • the retraction device (10) also has a damping device (100) which counteracts the spring energy store (81).
  • the housing (21) has a shell-shaped housing base (22) and a housing cover (23).
  • the two housing parts (22, 23) are connected to one another, for example, by means of a form-fitting connection. They can also be glued or screwed together.
  • the housing (21) On one of its narrow sides (24) oriented in the longitudinal direction (15), the housing (21) has a housing opening (25) through which the entrainment element (41) protrudes from the housing (21). This housing opening (25) adjoins an end face (26) of the housing (21) or is at a small distance from this end face (26).
  • the mutually facing inner side surfaces (27, 28) of the two housing parts (22, 23) are designed to be mirror images of each other, so that all guide and guide elements (29, 31, 37, 38) on the housing side both in the housing base (22) and in the housing are present in the housing cover (23).
  • a conductor track (29) and a guide track (31) are arranged on each of the inner side surfaces (27, 28).
  • the straight interconnect (29) oriented in the longitudinal direction (15) lies at least approximately in the middle. Their length oriented in the longitudinal direction (15) is, for example, greater than 80% of the length of the pull-in device (10).
  • the interconnect (29) has a constant width.
  • a guide track (31) is arranged on each of the two inner side surfaces (27, 28) between the interconnect (29) and the housing opening (25). This has a first section (32) oriented obliquely to the housing opening (25) and a second section (33) oriented parallel to the longitudinal direction (15). This second section (33) is oriented in the direction of the end face (26) adjacent to the housing opening (25). Its length is, for example, 55% of the length of the interconnect (29). Both sections (32, 33) are connected to one another by means of a curved transition section (34). In the exemplary embodiment, the guide track (31) has a constant width over its length.
  • the respective inner flanks of the guideways (31) oriented in the direction of the interconnect (29) form guide slots.
  • the first guide track section (32) thus has a first guide slot section (35) and the second guide track section (33) has a second guide slot section (36).
  • the two guide link sections (35, 36) enclose an obtuse angle ( ⁇ ), for example 100 degrees. This angle can be between ⁇ / 2 in radians and ⁇ lie, the included angle ( ⁇ ) being oriented in the direction of the interconnect (29) and ⁇ being the number of circles.
  • both cylinder slide tracks (37, 38) are arranged parallel to one another. Both cylinder slideways (37, 38) oriented in the longitudinal direction (15) have the same length in the exemplary embodiment, e.g. 52% of the length of the guide path (29).
  • the cylinder sliding path (38) further away from the conductive path (29) is delimited on the end face (26) by means of a housing support surface (39).
  • the entrainment element (41) is designed symmetrically to a central longitudinal plane of the draw-in device (10) which penetrates the housing opening (25).

  • the catch area (44) faces the first guide track section (32), a holding area (32). On a locking pin (45) it has an opening (49) and an actuating surface (48) oriented against the closing direction (16). The connection of the actuating surface (48) to the closest guide element (42) is thus designed to be elastically deformable.
  • the catch area (44) is delimited by means of a second catch pin (46).
  • the driving area (52) is, for example, U-shaped and is arranged between the catch pin (46) and a thrust pin (47).

In the exemplary embodiment, its diameter is 98% of the height of the guide track (31), which is oriented parallel to the aforementioned central longitudinal plane. They are spaced from one another by the reference distance (L), cf. Figure 12 .
  • the reference distance (L) is the distance between the center lines of the guide pins (42, 43) from one another.
  • the center line of the first bearing pin (42) is the origin (8) of a coordinate system lying parallel to the central longitudinal plane, the abscissa (6) of which points as a half-line in the direction of the center line of the second bearing pin (43).
  • the positive ordinate (7) normal to the abscissa (6) points in the direction of the capture area (44).
  • the abscissa (6) is referred to below as the x-axis and the ordinate (7) as the y-axis.
  • the bearing elements (42, 43) can also have cylindrical section-shaped jacket surfaces in certain areas, which can be contacted with the guide link sections (35, 36).
  • the reference distance (L) is then the distance between the imaginary radius center lines of the bearing elements (42, 43).
  • the two opposing third bearing elements (56) are designed as bearing journals (56). In the direction normal to the aforementioned central longitudinal plane, these are shorter than the first bearing elements (42) and the second bearing elements (43).
  • the geometric center line of the third bearing elements (56) lies in the illustration of Figure 12 below the half-line forming the abscissa (6).
  • the distance (79) of the third bearing element (56) to The abscissa (6) is greater than the difference between the product of the length (L) and the cotangent of the angle ( ⁇ ) and the product of the tangent of half the pivot angle ( ⁇ ) and the distance between the plumb line (57) of the third bearing element (56) ) to the origin (8).

  • the center line of the respective third bearing element (56) is located in the area of the angle ( ⁇ ) enclosed by the guide link sections (35, 36).

  • the thrust direction (58) of the sliding pivot joint (63) is directed normal to the longitudinal direction (15).
  • the angle can, however, also be designed differently, the first guide link section (35) and the thrust direction (58) enclosing an acute angle, the apex of which is on the side of the abscissa (6) facing away from the third bearing element (56).

  • the guide cheeks (64, 65) are connected to one another at least in the area of the base (66) facing away from the entrainment element (41) and in the area pointing in the opening direction (17). It is also conceivable to design the driver element guide part (61) in the region of the guide cheeks (64, 65) as a largely closed profile.
  • An arcuate elongated hole (67) is arranged in each of the guide cheeks (64, 65).
  • the mean radius of the respective arc is 95% of the reference distance (L).
  • the center of the radius lies in the representations of Figures 1 to 3 below the triangle formed by the three bearing elements (42, 43, 56).

  • the upper end of the individual elongated hole (67) in each case forms a cap-like stop (68). These stops (68) overlap the respective first bearing element (42) on both sides of the driver element (41).
  • the distance between the stops (68) and the second guide link section (36), oriented normal to the longitudinal direction (15), can be smaller than the width of the second guide track section (33) oriented in the same direction.
