Definitions
- the invention relates to a differential pull-out guide for pull-out furniture parts, with a carcass rail that can be attached to a furniture carcass, a pull-out rail that can be attached to a pull-out furniture part, and a pull-out rail that is arranged between the carcass rail and the pull-out rail
- Center rail wherein the pull-out rail and the center rail can be pulled out in a pull-out direction, starting from a closed position of the differential pull-out guide up to an open position of the differential pull-out guide, and the pulling out of the center rail from the carcass rail in the open position of the differential pull-out guide by a stop element of the carcass rail, on the one contact surface of the center rail, is limited, with an actuating part on the center rail in the region of the rear end of the center rail between a release position in which the center rail can be tilted relative to the carcass rail about a horizontal axis lying at right angles to the extension direction of the center rail from a normal position into a tilted position is, in which its rear end is lowered compared to the normal position and the
- Stop surface of the center rail for removing the center rail from the carcass rail under the stop element of the carcass rail can be guided past the latter, and a locking position in which the center rail is blocked against tilting from the normal position into the tilted position, is adjustably mounted and is mounted on a base body of the control part a lateral guide roller is rotatably mounted, the interacts with a vertical web of the cabinet rail.
- a differential pull-out guide of the type mentioned can be seen from EP 1795 088 B1.
- the center rail moves synchronously with the pull-out rail, covering in each case half the distance of the pull-out rail.
- the center rail has a load-transmitting differential roller for this purpose, which rolls between the tracks of the pull-out rail and the carcass rail.
- all the rollers of the pull-out guide are usually rotatably mounted on the middle rail.
- the carcass rail has a stop element, against which a stop surface of the center rail abuts when the center rail is in the extended state.
- an actuating part which is arranged in the region of the rear end of the center rail and is adjustably mounted between a release position and a blocking position is used.
- the center rail In the release position of the actuating part, the center rail can be tilted from a normal position into a tilted position relative to the carcass rail about a horizontal axis that is at right angles to the pull-out direction of the center rail.
- the rear end of the middle rail is lowered compared to the normal position. This allows the stop surface of the center rail under the Stop element of the body rail are guided past this and the center rail can be completely pulled out of the body rail.
- the middle rail In the locking position of the actuating part, the middle rail is blocked against tilting from the normal position into the tilted position, so that the middle rail cannot be removed from the cabinet rail.
- a roller is rotatably mounted on the control part about a horizontal axis which is at right angles to the pull-out direction and which interacts with an upwardly directed track of the carcass rail. If an attempt is made to tilt the center rail from the normal position to the tilted position when the control part is in the locked position, this roller of the control part is pressed against the track of the cabinet rail, thereby blocking the tilting.
- the actuating part In the release position, on the other hand, the actuating part can pivot about a horizontal axis that is at right angles to the pull-out direction.
- a lateral guide roller is also rotatably mounted on the control part and interacts with a vertical web of the carcass rail.
- the lateral stability of the pull-out guide against a load on the middle rail towards the side facing away from the vertical web of the carcass rail is thereby improved, in particular when the pull-out guide is in the open state.
- pull-out guides with self-retracting devices in which the pull-out rail is automatically retracted over a final section of the insertion path. It is advantageous if such self-retracting devices are integrated into the pull-out guide.
- a pull-out guide with an integrated self-retracting device can be found, for example, in WO 2008/119091 A1.
- the center rail in the area of its rear end a section over a part of its height.
- a roller is located above this cutout at the rear end of the center rail, which cooperates with a downward-pointing track of the body rail.
- An auxiliary roller is located in front of this cut-out, which interacts with the same tracks as the differential roller and which, when the pull-out guide is pushed in, can prevent the rear end of the center rail and the rear end of the pull-out rail from tipping down, as is also common with differential pull-outs. Due to the section of the center rail located behind the auxiliary roller, it is not possible to attach an actuating part at this point, which can be adjusted between a release position and a blocked position and in the release position allows the center rail to be tilted from a normal position to a tilted position in order to move the center rail out of the Take out the body rail, and blocked such tilting in the locking slope.
- a stop element arranged on the center rail can thus itself be adjusted between an active position, in which it interacts with a stop element of the carcass rail in order to limit the pulling out of the center rail from the carcass rail, and a passive position, in which it disengages from the stop element of the carcass rail is brought to allow the center rail to be fully extracted from the body rail.
- an adjustable stop element is disadvantageous in terms of operation, construction and durability.
- the possible overall height of a self-retracting device is limited by the cutout located only in a lower part of the center rail at the rear end of the center rail, so that limitations in terms of the formation of the Self-retracting device exist.
- the center rail were to be shortened overall, the lateral stability of the pull-out guide would be reduced.
- the object of the invention is to provide an advantageous differential pull-out guide of the type mentioned at the outset, which in the region of the rear end of the body rail has the largest possible installation space for equipping the pull-out guide with a
- the middle rail is shorter than the body rail and shorter than the pull-out rail and the rear end of the middle rail is offset forwards in the inserted state of the differential pull-out guide relative to the rear end of the body rail and compared to the rear end of the pull-out rail.
- the lateral guide roller of the control element arranged in the area of the rear end of the central rail not only interacts with the vertical web of the cabinet rail, but also works together with a vertical web of the pull-out rail on the side of the control part opposite the vertical web of the cabinet rail, or it is an addition to the base body of the control part - Lateral guide roller rotatably mounted, which cooperates with the vertical web of the pull-out rail on the opposite side of the control part to the vertical web of the carcass rail.
- the design according to the invention creates an installation space in the area of the rear end of the carcass rail provided which extends substantially over the entire height of the cabinet rail.
- Differential pull-out guided pull-out furniture part is stable in relation to a force acting in the sense of a rotation about a vertical axis.

- the body rail and the pull-out rail are preferably of the same length and, in the closed position of the differential pull-out guide, are flush with one another both at their front and at their rear ends.
- a roller is rotatably mounted on the base body of the actuating part, which, starting from the closed state of the differential pull-out guide, rolls over a first section of the pull-out of the differential pull-out guide between an upward-pointing track of the body rail and a downward-pointing track of the pull-out rail and a load can be transferred from the pull-out rail to the body rail via this section of the pull-out of the differential pull-out guide.
- another auxiliary roller arranged between the differential roller and the actuating part can also be dispensed with, which over a first section of the extension of the differential pull-out guide between the upward running track of the body rail and the downward running track of the pull-out rail.
- the roller of the control part could also only interact with the upwardly directed track of the body rail and an additional roller could also be rotatably mounted on the base body of the control part, which at least over a first section of the extension of the differential pull-out guide starting from the closed position of the differential pull-out guide with the downward running track of the pull-out rail interacts, with a load being transferrable from the pull-out rail to the body rail via the additional roller, the base body of the actuating part and the roller.
- the control part in the release position for lowering the rear end of the center rail relative to the center rail, can be pivoted about a horizontal pivot axis that is at right angles to the pull-out direction, and in the locking position it is locked against pivoting about the pivot axis, with the pivot axis of the control part being further forward than the lateral guide roller of the Control part (13) is arranged.
- the pivot axis of the actuating part can be displaced relative to the middle rail.
- the pivoting of the control part about the pivot axis for lowering the rear end of the center rail is blocked by a retaining surface of the center rail and in the release position, the control part except Engaged brought by the restraining surface.

- FIG. The lower section of the vertical web 2a, the lower horizontal web 2c and the vertical section 2b together form a U-shaped section of the center rail 2 when viewed from the front or seen in the cross section of the center rail.
- a stop element 11 of the body rail, with which a stop surface 12 of the center rail 2 interacts, serves to limit the extension of the center rail 2 from the body rail 1 in the extended position of the center rail 2 .
- the stop element 11 of the carcass rail 3 is formed by a tongue which is punched out of the upper horizontal web 3c and bent downwards.
- the stop surface 12 of the center rail 2 is formed by the front surface of a section of the vertical web 2a of the center rail 2 that protrudes upwards in the region of the rear end of the center rail 2 . In the extended position of the center rail 2, the stop surface 12 runs against the Stop element 11, as can be seen from FIG.
- an adjusting part 13 which is explained in more detail below and which, in a locking position, prevents the center rail 2 from being tilted from a normal position into a tilted position (cf. FIG. 21) by lowering its rear end , in which the stop surface 12 can be passed under the stop element 11.
- the insertion of the center rail 2 into the pull-out rail 1 is limited by a contact surface 3e of the body rail 3, against which the control part 13 runs in the pushed-in position of the center rail 2, as will be explained in more detail below.
- a securing part 17 is mounted at the front end of the center rail 2 so as to be rotatable about a horizontal axis.
- the control part 13 In a rear end section of the center rail 2, in a lower area of the center rail, the control part 13 is positioned between a blocking position (cf. Figs. 1-3, 6-8, 23 and 24) and a release position (cf. Figs. 9, 10, 21 and 22) adjustable.
- a blocking position cf. Figs. 1-3, 6-8, 23 and 24
- a release position cf. Figs. 9, 10, 21 and 22
- the actuating part 13 In the release position, the actuating part 13 can be pivoted about a pivot axis 14 that is horizontal and perpendicular to the pull-out direction 6 .
- the blocking position the pivoting of the actuating part 13 about the pivot axis 14 is blocked.
- the pivot axis 14 is formed by axle journals 13a of the actuating part 13 , which are arranged on the outer sides of two arms 13b of a base body 13e of the actuating part 13 that project forward.
- the axle journals 13a engage in elongated holes 15 in the middle rail 2 .
- the elongated holes 15 are arranged in opposite vertical sections of the center rail 2 .
- One of these vertical sections, in which one of the elongated holes 15 is arranged, is formed by the lower section of the vertical web 2a of the center rail 2.
- the opposite long hole 15 is arranged in the vertical section 2b of the center rail.
- the elongated holes 15 extend at least essentially in a horizontal direction parallel to the pull-out direction ("substantially” in this context means a deviation of less than +/- 10°). the pivot axis 14 can be displaced.
- the actuating part 13 is in the locked position.
- the actuating part 13 is in the release position.
- the elongated holes 15 preferably have constrictions in a central region.
- the arms 13b In order to insert the axle journals 13a into the elongated holes 15 when assembling the actuating part 13, the arms 13b can be inserted in be bent towards each other. In order to keep the axle journals 13a even more securely in the elongated holes 15, the arms 13b could be connected at their front ends by a spring element counteracting compression.
- This contact point 13c is formed in the exemplary embodiment from the respective lowest point of a roller 13d of the actuating part 13 rotatably mounted on the base body 13e of the actuating part 13, as is preferred.
- the roller 13d is arranged in the space between the arms 13b.
- the lower horizontal bar 2c of the center rail 2 has a cutout in the area of the roller 13d.
- the illustrated embodiment could also be modified in such a way that an additional auxiliary roller is rotatably mounted on the center rail 2 in the area between the differential roller and the adjusting part 13, which cooperates with the same raceways as the differential roller 7.
- Such auxiliary roles are in conventional
- the roller 13d rotatably mounted on the setting part could also be omitted.
- the lower end of a contact section 13i of the base body 13e would then form such a contact point.
- the base body 13e shown in the exemplary embodiment can thus be used both, as shown, with a roller 13d and in applications without a roller 13d.
- the actuating part In the locking position of the actuating part 13, the actuating part is blocked by a retaining surface 2d of the center rail 2 against pivoting about the pivot axis 14, so that the contact point 13c moves upwards.
- this retaining surface 2d is formed by a rearward-projecting extension of the vertical section 2b of the central rail 2, which is located above the base body 13e of the actuating part 13.
- the contact section 13i could also have a forward-projecting projection, which interacts with a projection of the center rail that protrudes in the area next to the roller 13d from the lower end of the vertical section 2b in the direction of the roller 13d, which forms the restraining surface trains.
- the base body 13e disengages from the retaining surface 2d (ie lies behind it). It is thus a pivoting of the actuator about the pivot axis 14 released while raising the contact point 13c.
- the center rail 2 can be tilted from its normal position, which it occupies when the control part 13 is in the locked position, into a tilted position in which the rear end of the center rail 2 is lowered in relation to the normal position.
- FIG. 23 shows the normal position of the center rail 2 when the control part 13 is in the blocking position.
- the control part is in the release position adjusted, but the middle rail is still in the normal position.
- tongue-shaped spring elements 13j of the base body 13e come into contact with the section of the lower horizontal web 2c of the middle rail 2 lying in front of the cutout for the roller 13d and are elastically deflected. These spring elements 13j therefore bring about a restoring force on the actuating part 13 in the sense of pivoting it back into the position in which it can be moved into the locked position.
- At least one spring element for resetting the pivoted control part could also be designed in a different way
- contact surface 3e is formed by a tab punched out of vertical web 3d and bent over.
- the roller 13d of the actuating part 13 rolls over a first section of the extension of the differential pull-out guide, starting from the closed position
- the roller 13d also assumes the function of an auxiliary roller arranged in conventional differential pull-out guides between the differential roller and the rear end of the body rail, which is omitted here.
- the middle rail 2 is shorter than the body rail 3 and shorter than the pull-out rail 1 and the rear end of the middle rail is offset forwards in the closed state of the differential pull-out guide relative to the rear end of the body rail 3 and compared to the rear end of the pull-out rail 1. This can be seen particularly well from FIG.
- an installation space is formed in the region of the rear end of the carcass rail, in which space a self-retracting device can be arranged.
- a self-retracting device 16 integrated into the differential pull-out guide is indicated only in FIG. 18 in a highly schematic manner by dashed lines.
- Self-retracting devices for pull-out guides including those that are integrated into the pull-out guide, are known and common. Such self-retracting devices usually have a spring-loaded tilting slide.
- the pull-out rail 1 and the body rail 3 are of the same length in the exemplary embodiment, as is preferred, and close in the closed position
- the distance a of the rear end of the center rail 2 from the rear end of the body rail 3 is in the closed Position of the differential pull-out guide is preferably more than 5% of the length of the body rail 3, particularly preferably more than 10%. In the exemplary embodiment, the distance a is approximately 15% of the length of the cabinet rail 3.
- 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.
