  • a lateral guide roller 13f is rotatably mounted about a vertical axis on the base body 13e of the actuating part 13 .
  • This lateral guide roller 13f acts on one side of the control part 13 with the vertical bar 3d of the carcass rail 3 and on the opposite side of the control part 13 with the vertical bar 1d of the pull-out rail 1 (cf. in particular FIGS. 19 and 20).
  • good lateral stability of the pull-out guide is achieved despite the shorter design of the middle rail 2, even in the closed position of the pull-out guide and over a first section of the pull-out of the pull-out guide.
  • Differential pull-out guide opposed to high resistance.
  • the running properties of the pull-out guide are improved by reducing friction.
  • the lateral guide roller that interacts with both the vertical web 3d of the carcass rail 3 and the vertical web 1d of the extension rail 1 is preferably 10% to 30% of the total extension distance.
  • the insertion of the center rail 2 removed from the cabinet rail 3 into the cabinet rail 3 is explained below with reference to FIGS. 21-23 (the securing part 17 on the center rail is not shown in these figures).
  • the control part 13 is first moved into the release position. As a result, the center rail 2 is pivoted into the tilted position and its rear end is inserted into the space between the horizontal webs 3b, 3c of the cabinet rail, with the control part 13 being pivoted about the pivot axis 14.
  • FIG. 21 shows the state when the stop surface 12 of the center rail 2 has just been guided through under the stop element 11 of the cabinet rail 3 .
  • FIG. 22 shows the state in which the base body 13e runs against the contact surface 3e of the carcass rail 3. This is the case shortly before the middle rail 2 reaches the pushed-in position. If the center rail is now fully retracted into the pushed-in position, the control part 13 is moved from the contact surface 3e into the locked position, see Fig. 23. This adjustment of the control part 13 from the release position to the locked position thus takes place automatically when the center rail is pushed in the stowed position.
  • the stop surface 12 of the middle rail 2 runs against the stop element 11 of the body rail 3 in the pulled-out position of the middle rail, as a result of which further extension of the middle rail 2 is blocked, cf. Fig. 24.
  • the center rail 2 is later to be completely removed from the cabinet rail 3 again, the center rail 2 is pulled out into the extended position according to FIG. 24 and the control part 13 is moved into the release position.
  • the stop surface 12 of the center rail 2 can be passed under the stop element 11 of the body rail 3, whereupon the center rail 2 can be pulled completely out of the body rail 3.
  • a second embodiment of the invention with a modified actuator is explained below with reference to FIGS. 25-31. Apart from the differences described below, the design corresponds to that of the first exemplary embodiment and the description of the first exemplary embodiment and the modifications described therein can be used in an analogous manner.
  • the roller 13d of the actuating part 13 is designed to be smaller here and interacts only with the upwardly directed track 3a of the lower horizontal web 3b of the carcass rail 3.
  • an additional roller 13g is also mounted on the base body 13e of the actuating part 13 so as to be rotatable about a horizontal axis perpendicular to the pull-out direction 6 . This acts only with the downward running track 1a of the horizontal bar 1b of the pull-out rail 1.
  • the possible load transfer from the pull-out rail 1 to the cabinet rail 3 via the control part 13 takes place in this exemplary embodiment via the additional roller 13g, the base body 13e and the roller 13d.
  • the lateral guide roller 13f is smaller in this exemplary embodiment and only interacts with the vertical bar 3d of the carcass rail 3, cf. in particular FIGS . This can be seen in particular from FIGS. 30 and 31. If, in the closed position of the pull-out guide and in a first section of the pull-out of the pull-out guide, a force directed towards the carcass rail 3 acts on the rear end of the pull-out rail 1, this force is transmitted via the lateral guide roller 13f, the base body 13e and the additional lateral guide roller 13h transferred to the vertical bar 3d of the cabinet rail 3.
  • Pull-out rail 1 cooperates is preferably 10% to
  • the adjusting part 13 could have a roller 13d, which interacts with the opposite running tracks of the extension rail and carcass rail and a lateral guide roller and additional lateral guide roller, one of which is connected to the vertical web of the Body rail and the other interacts with the vertical web of the extension rail, or the control part could have a roller and an additional roller, one of which interacts with the career of the body rail and the other with the career of the extension rail, and have a lateral guide roller, which both with the vertical bar of the cabinet rail as well interacts with the vertical bar of the pull-out rail.

Abstract

L'invention concerne une glissière de tiroir télescopique pour des parties de meubles amovibles, comprenant un rail de corps (3), un rail d'extraction (1) et un rail central (2), une pièce de réglage (13) du un rail central (2) étant montée de manière à pouvoir être réglée entre une position de libération, le rail central (2) pouvant être basculé par rapport au rail de corps (3) et une surface d'arrêt (12) du rail central (2) pouvant être déplacé au-delà du rail de corps (3), sous un élément d'arrêt (11) du rail de corps, et une position de blocage. Un rouleau de guidage latéral (13f) est monté en rotation sur la partie de réglage (13) et interagit avec une traverse verticale (3d) du rail de corps (3). Le rail central (2) est plus court que le rail de corps (3) et le rail d'extraction (1). Le galet de guidage latéral (13f) de la partie de réglage (13) interagit, sur le côté de la partie de réglage (13) opposé à la traverse verticale (3d) du rail de corps (3), avec une traverse verticale (1d) du rail d'extraction (1), ou un galet de guidage latéral supplémentaire (13h) est monté de manière rotative sur la partie de réglage (13) et interagit, sur le côté de la partie de réglage (13) opposé à la traverse verticale (3d) du rail de corps (3), avec la traverse verticale (1d) du rail d'extraction (1).
