Definitions

  • the present invention relates to a pull-out for drawers with a first and at least one second rail, wherein between these two rails at least one carriage with load-transmitting rolling elements is arranged, wherein the carriage - especially in a deviation from the differential run between the rails - to the second rail is detachable.
  • carriage errors Due to the slippage between the rollers of the carriage and the guide profiles of the rails is not always ensured that when removing and inserting the drawer, the carriage exactly halfway the pull-back rail. This creates so-called carriage errors, i. The position of the carriages is incorrect with respect to the support and extension rails. Such carriage errors can sometimes result in the drawer being left open in normal use.
  • damping devices In pull-out with a locking device additional damping devices are often provided which dampen the drawer over the last movement path to the respective end position, so that the drawer is not drawn with too much momentum in the furniture body.
  • dampers reduce the closing dynamics of the drawer so much that a occurred during the movement of the drawer carriage error can not be compensated for lack of kinetic energy.
  • the carriage with locking means are provided which lock the carriage at a deviation from the differential running between the rails at predetermined locations between the two end positions on one of the rails, said lock being releasable to each other by the method of rails.
  • the carriages are movable in the direction of the end positions beyond the predetermined points after releasing the lock. It is thus ensured that the correction of the position of the carriage takes place before it has reached the end of the insertion path.
  • the carriage When a carriage error occurs, which usually moves in the size range of only a few millimeters, the carriage can be coupled over a relatively short distance on the loosely guided rolling or sliding body with the movement of the drawer whose speed - as usual in a differential extract - about twice the speed of the carriage. In the course of this coupling, the carriage error is corrected.
  • the rolling or sliding body is movable into an escape in which the clutch is released, so that the drawer is substantially free to move in the direction of the open position, wherein the uncoupled rolling or sliding body at a predetermined exit point the escape emerges and is movable as part of the carriage in the direction of the outer end position.
  • the rolling or sliding body preferably gravity loaded, is mounted vertically movable substantially perpendicular to the withdrawal direction of the rails.
  • the diverter comprises a recess arranged or formed in the first rail, preferably an oblong hole, into which the rolling or sliding body can be immersed so that the coupling between the carriage and the second rail can be released ,
  • the rolling or sliding remains uncoupled with the coupling part. It is advantageous if, when closing the rails, the coupling part can be brought into contact with the rolling or sliding body and, at the same time, can be guided laterally past the escape. The rolling or sliding body is to be moved back into the starting position for the next opening movement of the drawer in the course of the closing process, which is why the rolling or sliding body is guided around a bypass around the turnout and should not enter the turnout. For this purpose, a certain lateral displacement possibility (in a plan view of the rail and offset to the withdrawal direction of the same) is allowed.
  • the rolling or sliding body in the rail plane is mounted transversely, preferably substantially perpendicular, to the pull-out of the drawer movable.
  • the carriage has a guide in which the rolling or sliding body is mounted limited movable within predetermined limits.
  • the rolling or sliding body can be acted upon within the guide by a spring device by which the rolling or sliding body when closing the drawer is movable again in a provided for the opening movement of the drawer starting position. The coupling member pushes the rolling or sliding during the closing process laterally past the escape, whereupon the proposed spring device compensates for this lateral offset.
  • the drawer according to the invention is characterized by a pull-out of the type described, the furniture of the invention has a drawer of the aforementioned type.
  • Fig. 1 shows a cabinet-shaped furniture 1 with a furniture body 2, on the lateral inner walls in each case a pull-out guide 3 according to the invention is attached.
  • the pull-out guide 3 comprises a rail 4 to be mounted on the furniture body 2 and at least one rail 5 displaceably mounted thereon and to be fastened to the drawer 6.
  • the pull-out guide 3 expediently comprises a three-part rail system, so that the drawer 6 can be completely pulled out of the furniture carcass 2.
  • a carcass rail, a Store rail and provided between these two rails slidably guided center rail.
  • Fig. 2 shows a perspective view of the pull-3 with the furniture body 2 to be fastened rail 4 and the extendable rail 5, which is to be attached to the drawer 6.
  • a rail 7, which is provided as a between the two rails 4, 5 arranged center rail.
  • the middle rail is referred to as the first rail 7, the drawer rail as the second rail 5 and the carcass rail as the third rail 4.
  • a schematically indicated coupling part 8 which projects downwards on the underside of the catwalk of the displaceable second rail 5 and is arranged as an inclined surface transversely to the withdrawal direction of the rail 5, wherein the function of the coupling part 8 is described below.
  • Fig. 3 shows a portion of the pull-3 in an exploded view with the first rail 7 (middle rail) and the second rail 5 (drawer rail) with a movable between these two rails 5, 7 carriage 9.
  • the carriage 9 comprises in a known manner load-transmitting rolling elements 10 with horizontal Rotary axes and at least one 19.
  • the carriage 9 on a rolling or sliding body 12 which is formed as a ball and is denoted below by the reference numeral 12a.
  • the ball 12a is guided loosely within a slot-like guide 13.
  • the ball 12a acts in the assembly position temporarily with the at the bottom of the catwalk of the second rail 5 downwardly projecting coupling part 8 together.
  • the first rail 7 has an escape 14 in the form of an axially to the withdrawal direction of the drawer 6 arranged long hole.
  • the rails 5, 7 have end stops 15a, 15b, wherein the carriage 9 should be in the closed position of the two rails 5, 7 to each other ideally spaced from the two end stops 15a, 15b should be.
  • Fig. 4a, 4b show this ideal case of the position of the carriage 9, which is slidably mounted between the rails 5, 7.
  • Fig. 4b shows a plan view of the pull-3 in the closed position of the rails 5, 7. Since the carriage 9 would not be apparent here, a dashed line of the arranged between the rails 5, 7 components is shown.
  • Fig. 4a now shows the ideal Position of the carriage 9, since this is in the closed position of the rails 5, 7 shown spaced from the end stops 15a and 15b. A correction of the carriage position is therefore not necessary.
  • Fig. 4b shows the detail area according to Fig. 4a in an enlarged view. Here, in the guide 13 loosely guided ball 12a can be seen.
  • a spring device 16 in the form of a molded, resiliently formed plastic part can be seen, through which the ball 12a during the closing operation of the drawer 6 is again moved to the position shown to produce a ready position for the next extraction process.
  • Clearly recognizable is also formed as an inclined surface coupling part 8 on the underside of the extendable second rail 5 and formed as an elongated hole turnout 14 for the ball 12a.
  • Fig. 5a, 5b show an analogous representation to the Fig. 4a and 4b , - Due to the slippage between the rolling elements 10 and rails 5, 7 - a misalignment of the carriage 9 is present. This case occurs when the carriage 9 is already present at the end stop 15a of the first rail 7, before even the full closed position of the rails 5, 7 is reached each other. This leads to the consequence that the extendable second rail 5 would have to be pressed under pressure to produce the full closed position, the rail 5 is pushed over the rolling elements 10, which makes higher forces required and would bring corresponding wear of the carriage 9 with it. Moreover, this position of the carriage 9 would mean that in a proposed collection device with a damper, the drawer 6 could not be completely retracted into the furniture body 2.
  • the oblique coupling part 8 is now provided, which detects the ball 12a during the opening process of the drawer 6 due to its double speed relative to the carriage 9, thereby engaging the carriage 9 and forcibly leads this briefly at twice the speed.
  • the ball 12a reaches the diverter 14 when the drawer 6 is being pulled out, the ball 12a can dip therein, whereby the coupling is released and the coupling part 8 can overtake the carriage 9 unhindered.
  • the diverter 14 is designed so that the ball 12a may dip slightly, but can not completely fall through.
  • the meandering Spring buffer are formed, which is attenuated by these damper 20, the impact of the carriage 9 in its end positions.
  • Fig. 6a shows a schematic side view of the carriage 9 associated ball 12a corresponding to the temporally successive positions A to F during the opening movement in the direction of arrow S of the drawer 6.
  • the reference numeral 8 of the second rail 5 (pull-out) associated coupling part 8 is marked.
  • Fig. 6b shows a plan view of the first rail 7 (middle rail) with the respective positions of the ball 12 a, each of the upper position according to Fig. 6a correspond.
  • Fig. 6a and 6b So show temporal courses of the relative movement of the coupling part 8 and the ball 12a to the first rail 7 during the opening movement of the drawer 6, wherein a carriage error is corrected.
  • the coupling part 8 is still behind the ball 12a. It should be mentioned that - as in a differential extract usual - the pull-out 5 moves at about twice the speed of the carriage 9 (and thus the ball 12a).
  • the coupling part 8 has already overtaken the ball 12a, with the ball 12a (and thus the carriage 9) being coupled to the faster moving pull-out rail 5.
  • the ball 12a is thus clamped between the first rail 7 and the coupling part 8, so that thus the carriage 9 is moved together with the pull-5, namely at twice the speed.
  • the ball 12a can emerge as part of the moving carriage 9 again from the escape 14.
  • the position F shows the ball 12a of the carriage 9 on the way toward the end position of the carriage 9, the pull-out rail 5 with the coupling part 8 arranged thereon can be moved into the fully open position.
  • Fig. 7a and Fig. 7b show one to the Fig. 6a, 6b corresponding representation, by means of which the operation of the closing operation of the drawer to be explained.
  • the sequence of the sequence runs from right to left, ie starting from position A '(an open position of the drawer 6) up to the position F' (a position of the drawer 6 immediately preceding the closed position).
  • the drawer 6 thus moves in the closing direction in the direction of arrow S '.
  • the coupling part 8 of the pull-out rail 5 approaches the ball 12a coming from the right.
  • the coupling part 8 has overtaken the ball 12a of the carriage 9 and can be brought to this plant. It should be noted in this context that in the entire closing movement - in contrast to the opening movement - no frictional connection between the coupling part 8 and ball 12a is made.
  • the coupling part 8 can be brought into abutment only on the ball 12a, to the extent that the ball 12a is pressed by the coupling part 8 to bypass the escape 14 on the side, but otherwise the coupling part 8, the ball 12a pass unhindered.
  • the ball 12a is thus displaceable by the inclined surface of the coupling part 8 by the difference width .DELTA.B, as it is shown at position D '.
  • the ball 12a of the in Fig. 4b shown spring device 16 is again pressed into a provided for the next extension movement of the drawer 6 starting position, as shown in position F '.
  • the pull-out rail 5 can be moved with its coupling part 8 in the direction of the fully closed position.
  • Fig. 8a shows a perspective view of the underside of the pull-5, wherein the arranged coupling part 8 can be seen.
  • Fig. 8b shows an enlarged view of the in Fig. 8a circled area.
  • the coupling part 8 is arranged on a catwalk of the rail 5 transversely to the withdrawal direction (for example, within an angle between 10 ° and 90 °, preferably between 30 ° and 60 °). From the enlarged detail A of the coupling part 8 can be seen, which has a control edge 8a in the form of an inclined surface. If an occurring carriage error is corrected during the opening operation of the drawer, the ball 12a is in the parking position P during the correction (see position B, C according to FIG Fig.
  • the ball 12a follows from the opposite direction to the marked movement path R, in which the lateral displaceability by the difference width .DELTA.B (see position D 'according to FIG Fig. 7b ), the ball 12a being passed around the diverter 14.
  • the control edge 8a is arranged on the catwalk of the rail 5, that the ball 12a is laterally moved past it. After this passing, the ball 12a is pushed back by the spring device 16 back into its original trajectory.
  • Fig. 9 shows an exploded view of the pull-out according to the invention 3.
  • a first rail 7 (middle rail), a second rail mounted thereon 5 (drawer rail) and a third rail 4 (cabinet rail) are provided, which are designed to be movable relative to each other.
  • a third rail 4 (cabinet rail)
  • the pull-out guide 3 comprises a spring-loaded draw-in device 17, with which the extendable rails 5, 7 can be transported to their full closed position.
  • a damping device 18, preferably a piston-cylinder unit that can be filled with a fluid is provided.
  • the present invention is not limited to the embodiment shown, but includes all variants and technical equivalents, which may fall within the scope of the following claims. Also, the location selected in the description, such as top, bottom, side, etc., on the directly described and illustrated figure and are to be transferred in a change in position mutatis mutandis to the new situation. Since the carriage 9 tends to tend to assume a trailing position between the rails 5, 7, the description has provided a correction during the opening movement of the drawer 6. Of course, with appropriate means, a correction during the closing movement of the drawer 6 can be made.
