Definitions

  • the invention relates to a deceleration device with a housing, with a cylinder-piston unit mounted in the housing, having a cylinder and a piston, and with a driving element mounted in the housing so as to be displaceable between a non-positively and/or positively secured parking position and an end position and back, wherein the driving element loads the piston relative to the cylinder at least when moving in the direction of the end position, and wherein the driving element comprises a carriage with a first sliding and pivot pin and a pull pin pivotably mounted thereon in a pivot joint with a second sliding and pivot pin, wherein the sliding and pivot pins are inserted in a first guide track oriented in a longitudinal direction of the deceleration device and wherein the pull pin is rigidly connected to at least one guide pin guided in the housing and movable parallel to the carriage at least in a stroke section adjacent to the end position, as well as a combined acceleration and deceleration device with such a deceleration device and with a spring energy store that can be loaded and un
  • the present invention is based on the problem of developing a low-noise deceleration device with a long service life.
  • a stop pin is pivotally mounted in the slide.
  • the guide pin is inserted in a second guide track with a horizontal section and with an expansion arranged at an end facing away from a cylinder mount for the cylinder-piston unit and directed in the direction away from the first guide track.
  • the housing or the slide has a wedge-shaped mount that limits the swivel angle range of the pull pin in the parking position.
  • the opening of the wedge mount is oriented in the direction away from the cylinder mount so that the guide pin can be clamped in the wedge-shaped mount.
  • the swivel angle of the pull pin is greater than 90 degrees and less than 110 degrees.
  • the pull pin can be displaced from the parking position by means of a swivel movement of the stop pin relative to the slide.
  • the acceleration and deceleration device is designed in such a way that the spring energy storage is held on the slide and the housing.
  • the guide pin rests on a guide slot in the housing.
  • the The force component of the spring force is oriented parallel to the guide slot in the direction of the end position, so that the housing blocks a longitudinal displacement of the driving element.

  • a pull pin is pivoted relative to a carriage in the parking position.
  • the pull pin is clamped and secured to the carriage or the housing using a wedge holder.
  • the pull pin is loaded relative to the housing in the parking position, so that movement of the driving element in the closing direction is blocked.
  • the release from the parking position is achieved by a pivoting movement of the stop pin, which acts on the pull pin. This results in a slight gradient of the increase in forces on the pull pin and on the driving element, so that no impact noises are generated.

  • the spring energy storage device (15) is then connected to the traction cable (13).
  • This unit is then placed around the deflection rollers (53) and suspended in the carriage (62) and in the housing (31).
  • the tension spring (15) then acts on the carriage (62) via the deflection rollers (53).
  • the spring energy storage device (15) is thus held on the carriage (62) and the housing (31).
  • the guide pins (107) rest against the guide slots (55).
  • the force component of the spring force applied to the guide pin (107) and oriented parallel to the guide slot (55) points in the direction of the end position (22).
  • the guide pins (107) thus block the position of the driving element (61) relative to the housing (31).
  • these guide pins (107) simultaneously secure the position of the pull pin part (102) relative to the slide (62) by clamping in the wedge holder (48).
  • the position of the pull pin part (102) relative to the slide (62) in the parking position (23) can be secured by means of a force-fitting and/or form-fitting connection between the pull pin part (102) and the slide (62).
  • the driver element (61) is released from the parking position (23) as described in connection with the first embodiment. No impact noises are generated here. In this case too, the force on the push surface (65) is introduced into the cylinder-piston unit (111) without redirection. This avoids damage to the driver element (61) and/or the housing (31).
  • both the deceleration force of the deceleration device (21) and an acceleration force caused by the relaxing spring energy store (15) act on the driver element (61). Due to the long tension spring (15), there is a very flat spring characteristic curve. The resultant of the superimposed acceleration and deceleration forces moves the driver element (61) in a controlled manner into the end position (22). It remains here without striking anything.
  • the drawer is now closed, for example.
  • the driver element (61) When the drawer is opened, the driver element (61) is also pulled in the opening direction (3) in this embodiment.
  • the piston (115) is extended in the cylinder-piston unit (111).
  • the spring energy store (15) is charged.
  • the driver element (61) has reached the parking position (23)
  • the driver (2) is decoupled.
  • the drawer can now be opened further.
  • a two-part carrier element (61) is shown. This can be used both in a deceleration device (21) and in a combined acceleration and deceleration device (10), as described in connection with the previous embodiments.
  • the driving element (61) shown has a slide (62) and a double lever (81) pivotably mounted in it.
  • the pivot and sliding pins (74, 76) are in this Figure 13 not shown.
  • the representation of the Figure 13 shows the driving element (61) in the end position (22).
  • the carriage (62) is largely constructed in the same way as the Figure 3 shown slide (62).
  • the first sliding and pivot pin holder (67) is arranged below the thrust pin (64).
  • the thrust surface (65) is a continuous flat surface. It is arranged normal to the plane of the transverse openings (67, 68). In addition, a normal to the thrust surface (65) penetrates the piston rod head holder (63) or a stop surface of the piston rod (114) on the slide side.
  • the double lever (81) is pivotably mounted in the second sliding and pivot pin holder (68) of the slide (62).
  • the position of the second sliding and pivot pin holder (68) relative to the thrust surface (65) corresponds, for example, to the conditions of the Figure 3 shown carriage (62).
  • oval guide pin (107) lies in a plane parallel to the plane of the sliding and pivot pins (74, 76).
  • the guide pin (107) can also be Figure 5 The guide pin (107) shown in FIG.
  • the Figure 14 shows the double lever (81) in a side view. It has a pull pin (104) and a stop pin (84).
  • the pull pin (104) is designed like the one in the Figure 5 Its arrangement relative to the guide pins (107) also corresponds to the conditions of the Figure 5 shown drawbar part (102).
  • the stop pin (84) is formed onto the pull pin (104).
  • the stop pin (84) is connected to the pull pin (104) in the area of the guide pin (107).
  • the stop pin (84) is curved.
  • the imaginary center line of the curve (91) is oriented in the transverse direction (27) and lies above the stop pin (84) when the pull pin (104) is in the operating position (108). In this position of the double lever (81), see. Figure 13 , the stop pin (84) is located below the slide (62). The stop pin (84) is thus at least approximately perpendicular to the pull pin (104).
  • the stop pin (84) can be designed to be elastically deformable.
  • the arch (91) can be bent open. It is also conceivable to design the connection of the stop pin (84) to the tension pin (104) to be bendable.
  • the Figure 15 shows that in the Figures 13 and 14 illustrated driving element (61) in the parking position (23) in a housing bottom shell (32).
  • the housing bottom shell (32) is, for example, constructed as described in connection with the previous embodiments.
  • the carriage (62) is shown cut along a vertical central longitudinal plane.
  • the double lever (81) is pivoted relative to the end position (22), e.g. by an angle of 95 degrees.
  • the pivoting direction of the pull pin is oriented in the opening direction (3) when pivoting into the parking position (23).
  • the pull pin (104) In the parking position (23) the pull pin (104) has the same position relative to the slide (62) as in the pull pin (104) described in connection with the previous embodiments.
  • the guide pins (107) are secured in the wedge-shaped receptacles (48) of the second guide tracks (44). This both fixes the parking position (23) and blocks the driving element (61) from being moved in the closing direction (4).
  • the stop pin (84) protrudes from the slide (62) by a third of its length. It protrudes into the drive recess (75). The part of the stop pin (84) protruding from the slide (62) is offset in the direction of the thrust surface (65) from the second pivoting and sliding pin (76).
  • the driver (2) When the driver (2) moves relative to the driver element (61) in the closing direction (4), the driver (2) first contacts the stop pin (84).
  • the double lever (81) experiences a torque about the swivel joint (78) with the second sliding and swivel pin (76).
  • the double lever (81) is swiveled clockwise. This releases the locking of the double lever (81), e.g. in the housing (31).
  • the double lever (81) leaves the parking position (23).
  • the pull pin (104) swiveled with the double lever (81) limits the play of the driver (2) relative to the driver element (61) in the opening direction (3).
  • the stop pin (84) is displaced into the carriage (62).
  • the guide pins (107) roll on the guide slots (55).
  • the double lever (81) is pivoted further.
  • the driver element (61) moves in the direction of the end position (22).
  • the deceleration device (21) and, if applicable, the acceleration device (11) act on the driver element (61), as described above.
