The invention relates to a pull-out device for a tall cabinet pull-out

• a fixed body rail, which can be fixed on the furniture body of the tall cabinet and has an upward open U-shaped cross-section with a horizontal base web and vertical side walls, on which inwardly projecting horizontal flanges are provided, with the body rail on the inside of the front face Support rollers arranged on the side cheeks are rotatably mounted, in the area of which the horizontal flanges have cutouts and which project above the side cheeks,
• an intermediate rail, which also has an upwardly open U-shaped cross section with a horizontal base web and vertical side cheeks, on which inwardly and outwardly projecting T-shaped horizontal flanges are provided, in the region of the rear end face of the intermediate rail on the outer sides of the side cheeks Arranged castors are rotatably supported, which protrude downward from the base web and
• a part which is displaceable with respect to the intermediate rail and has a bottom surface and side surfaces, rear rollers being rotatably mounted on the outer sides of the side surfaces in a rear region of the displaceable part and projecting downwards from the bottom surface of the part.

Such a pull-out device is known from AT-PS 406 006. It is there the slidable part is designed as a profile rail, and the intermediate rail has rotatable in its front area on its vertical side cheeks supported support rollers, which protrude above the T-shaped horizontal flanges. The profile rail, which can be pulled out from the intermediate rail, faces outwards cantilevered horizontal flanges on their vertical side cheeks, which roll on the support rollers of the intermediate rail.

Tall cabinets are known which are rotatable about a vertical axis on a pull-out device stored pull-out cabinets. Such a pull-out cupboard is usually in the retracted state of the puller with his Longitudinal side arranged parallel to the pull-out direction. On one or both long sides For example, exhibits can be attached. To the pull-out the cupboard pull-out is pivoted by 90 ° so that the Exhibits are visible from the front of the tall cabinet or are accessible.

Storage of such a rotatable tall cabinet pull-out on a pull-out device, as known from AT-PS 406 006 would have the disadvantage that after pulling out and swiveling the tall unit pull-out by 90 ° a front part of the pull-out profile rail follows the tall unit pull-out would protrude at the front and form a kind of trip rail. It was therefore already proposed a pull-out device for a pivotable To design the tall unit pull-out as a hanging guide. However, this is with one considerable manufacturing effort not only of the extractor, but also of the tall cabinet itself, since this is the weight of the loaded Must pull out tall cupboard pull-out.

In a further known pull-out device for a tall cabinet pull-out, which is pivotally mounted about a vertical axis, is one in the bottom of the Building recessed rail provided on which the pull-out cupboard load-bearing pivot bearing is slidably mounted. This pull-out device requires thus on-site measures and further contaminates the over time Groove of the rail embedded in the building floor, especially in its area outside the cupboard, and requires extensive cleaning.

Another tall cabinet with a swivel-mounted tall cabinet pull-out (= extendable part) is known from DE 93 16 213 U1. The puller is not described in detail here, it is only stated that it may be consists of three superimposed pull-out parts. The length of the extendable cabinet part is not much larger than its width, so that the problem of the formation of trip rails when pivoting the There is no 90 ° pull-out in the tall cupboard.

In the tall cabinet described in CH 460 709 A, the tall cabinet pull-out is in the area of the front end of an extendable rail rotatably mounted. The pull-out device is again not described in detail, but it can be seen from the pictures that it is a single extract is formed, the extendable rail is somewhat shorter than the fixed one Rail. The depth of the tall cabinet is not with this facility exploited and the cabinet pull-out is backwards from the vertical tilted.

The object of the invention is a pull-out device for a tall cabinet pull-out to provide which is pivotable about a vertical axis, the Cabinet depth is used as far as possible and in the extended and pivoted Condition of the tall unit pull-out if possible none before the tall unit pull-out protruding parts are present in the room. According to the invention With a pull-out device of the type mentioned at the beginning, this is achieved by that the length of the slidable part is less than 2/3 of the length of the Intermediate rail, preferably approximately half the length of the intermediate rail, is, with the tall cabinet pull-out on the sliding part or on a pivot bearing attached to the displaceable part, preferably in the area the front end of the movable part, is rotatably supported, and that in the area of the front end face of the displaceable part on the outer sides the side surfaces of the front castors are rotatably mounted, the opposite protrude downward from the bottom surface of the part.

In a preferred embodiment, this is slidable on the intermediate rail Part designed as a profile rail, which has an upwardly open U-shaped Cross section with a horizontal base bridge and vertical side walls and which within the U-shaped cross section of the intermediate rail is arranged. On this profile rail, the pull-out cupboard can do this load-bearing pivot bearings are attached.

The individual figures have different scales.

The body rail 2 which can be fixed on a furniture body 1 has a U-shaped one Cross section with two vertical side walls 3 and one of these side walls 3 connecting lower horizontal base web 4. The upper edges the side cheeks 3 are bent to form horizontal flanges 5 and directed inwards against the vertical center plane of this body rail 2. At the These horizontal flanges 5 are cut out at the front end of the body rail 2 (Recesses 21) and in this area are on the inside of the Sidewalls support rollers 6 freely rotatable, the horizontal flanges 5th protrude slightly above. If here and in the following of support rollers or Rollers are spoken in the majority, among them are each in one To understand cross-sectional plane of a profile rail pairs arranged roles. In the present case, two support rollers 6 are therefore at right angles to the plane of the drawing seen in Fig. 1 in a row (see. Fig. 2).

The intermediate rail 12, which also has a U-shaped cross section in turn has a horizontal base web 17 and laterally arranged on this vertical sidewalls 16. On the upper edges of the sidecars 16 are both outward and inward-facing, T-shaped horizontal flanges 13 provided. In the rear area of the intermediate rail 12 are rollers 15 freely rotatably mounted on the outer sides of the side wall 16, the opposite the base web 17 connecting the side walls 16 protrude somewhat downward (see Fig. 6). On the outward sections of the T-shaped horizontal flanges 13 are dent-like bends 18 projecting downwards arranged, which serve as a stop for the extension limit. On the front End of the intermediate rail 12 are the T-shaped horizontal flanges 13 in their cut out inwardly projecting section and form recesses 22 (cf. Fig. 8).

A part 7 which is displaceable with respect to the intermediate rail 12 is also shown as Profile rail formed and has a U-shaped cross section. The outside lying surfaces of the vertical side walls 23 of this rail Side surfaces of the slidable part 7 and the side cheeks 23 below connecting horizontal base web 24 forms the bottom surface with its underside 19 of the displaceable part 7. In the area of the rear end face of the slidable part are rotatably mounted on the outer sides of the side surfaces rear rollers 9 arranged opposite the bottom surface 24th protrude slightly downwards. In the area of the front end of part 7 are on the outer sides of the side surfaces 10 rotatably mounted front rollers 11 arranged, which is also somewhat opposite the bottom surface 24 of part 7 protrude downward.

In the area of the front end of the intermediate rail 12 there is a on the base web 17 Stop 14 provided.

All of these rails 2, 12 and 7 have approximately the same height H. The Diameter of the rollers and support rollers 6, 9, 11, 15 can be the same. Differently on the other hand, the widths B of these rails 2, 12, 7 are so dimensioned are that these rails 2, 12, 7 arranged in a chess-like manner 7 to 9, i.e., the open sides of all U-shaped ones Profile rails 2, 12, 7 are directed upwards, with the base webs 4, 17, 24 of all profile rails 2, 12, 7 lie directly one above the other, and only with a small distance. The vertical distances between two adjacent base webs 4, 17, 24 are essentially the same size and - based on the height H of the individual rails 2, 12, 7 - relatively small. This The distance is about 2/10 of the height H. The recesses 21, 22 are used to thread the profile rails 2, 12, 7 into one another.

The length I of the displaceable part 7 is approximately half the length L of the Intermediate rail 12. For the rotatable mounting of a tall unit pull-out 20 (= extendable part of the tall cabinet), of which only one frame in FIGS. 8 and 9 is shown, is in the region of the front end of the slidable Part of a pivot bearing in the open profile of the slidable formed as a profile rail Part 7 attachable. The pivot bearing 25 includes one with the displaceable Part 7 connected base part 26 and a displaceable relative to the base part Rotating part 27 on which the frame of the tall unit pull-out 20 is fixed is. For the rotatable connection of the rotating part 27 to the base part 26 can an axial bearing or plain bearing may be provided. The 180 ° against each other pivoted positions in which the frame of the tall unit pull-out 20 parallel to the profile rails 2, 12, 7, can be designed lockable.

In the retracted state of the tall unit pull-out 20, the rear end of the profile rail forming the displaceable part 7 terminates approximately with the rear ends of the intermediate rail 12 and the carcass rail 2. Corresponding, in the figures
stops, not shown, can be provided in a conventional manner. The long side of the tall unit pull-out 20 is parallel to the profile rails 2, 12, 7, wherein the length of the tall unit pull-out can essentially correspond to the length of the pull-out device (and thus the depth of the tall unit, not shown). When pulling out, the displaceable part 7 is moved relative to the intermediate rail 12 until it abuts the stop 14 of the intermediate rail 12. Furthermore, the intermediate rail 12 is pulled out of the body rail 2 until the stop formed by the bend 18. In this position, the rear end of the tall cabinet pull-out 20 lies in front of the front end of the cabinet rail 2 and thus in front of the furniture body 1 of the tall cabinet. The tall unit pull-out 20 can now be pivoted through 90 ° into the position shown in FIG. 9.

Instead of the displaceable part 7 designed as a profiled rail, this could be done also in the manner shown schematically in FIGS. 10 and 11 be trained. Here, the base part 26 'of the pivot bearing 25' is itself in the form of a carriage formed and has rear and front rollers 9, 11, which are free are rotatably arranged next to the side surfaces 10 of the base part 26 'and the Extend the bottom surface 19 of the base part 26 'somewhat downwards. On the base part 26 ', a plate-shaped rotating part 27' is rotatably mounted. The base part 26 'has about the height H of the intermediate rail 12, so that the rotating part 27 'above the T-shaped horizontal flange 13 of the intermediate rail 12 is located. On this Rotating part 27 ', the tall unit pull-out 20 can be rotatably fixed. Because the length of the displaceable part 7 'is significantly shorter than half the length of the intermediate rail 12, the displaceable part 7 'is in the retracted state of the pull-out not to move to the rear end of the intermediate rail 12 when the Tall unit pull-out 20 is essentially the length of the intermediate rail has the appropriate length. A corresponding, on the intermediate rail 12 the displacement of part 7 'to the rear end of the intermediate rail 12 limiting stop.

In principle, it would also be conceivable and possible to place additional intermediate rails between to use the body rail 2 and the intermediate rail 12, which castors at the rear end (corresponding to the intermediate rail 12) and at the front end the T-shaped horizontal flanges projecting upwards Have support rollers (corresponding to the support rollers 6 of the cabinet rail 2). The length of the movable part is in any case shorter than 2/3 of the length of the Intermediate rail 12, the cabinet extension in the depth of the tall cabinet can take advantage of, without being pulled out and swiveled Condition of the cabinet pull-out tripping rails protruding into the room be formed.
