The object of the invention is to provide an improved device for guiding a movable furniture part relative to a furniture body, in particular with regard to a compact and simple design.

The object is solved by the features of the independent claims.

Advantageous and expedient embodiments, variants and developments of the invention are set out in the dependent claims.

The invention is based on a device for guiding a movable furniture part, in particular a drawer, which can be slidably accommodated on a furniture body by means of the device, the device comprising a body rail and a drawer rail, the body rail on furniture carcass can be arranged, with the displaceably mounted drawer rail being movable relative to the carcass rail in an opening and closing direction, with the carcass rail and the drawer rail each having at least one flat running surface, with the running surface of the drawer rail being flat throughout, with the relative movement between the drawer rail and body rail load-transmitting rolling elements can be moved along the running surface of the body rail and drawer rail, the running surface extending in a longitudinal extension and width extension, the longitudinal extension being formed perpendicularly to the width extension, the longitudinal extension of the running surface being aligned in the opening and closing direction of the drawer rail.

The device is preferably a drawer pull-out guide, in particular a partial pull-out. The piece of furniture preferably has two identical devices, with one device in each case being arranged between a side wall of the furniture body and a side wall of the movable furniture part. In the assembled state, the carcass rail is preferably fastened to the furniture carcass and the drawer rail is fastened to the movable furniture part. Advantageously, the drawer rail with the movable furniture part arranged thereon or on it is linearly movable relative to the carcass rail arranged, for example, in a fixed position on a side wall of the furniture carcass, with the drawer rail being able to be moved relative to the carcass rail in the opening and closing direction.

The movable furniture part preferably rests on a catwalk of the drawer rail, in particular on a surface of the catwalk of the drawer rail that is aligned horizontally or at least almost horizontally when the device is installed. Preferably, the movable furniture part rests on an upper surface of the catwalk of the drawer rail, with a lower surface of the Catwalk of the drawer rail preferably rolling elements are movable along. The top and bottom surfaces are preferably located opposite each other on the runway and are separated by the material thickness of the runway of the drawer slide. Preferably, the lower surface of the runner of the drawer slide forms a running surface. Advantageously, rolling bodies, such as balls or rollers, are arranged between the lower surface or the running surface of the drawer rail and a running surface of the carcass rail.

The carcass rail advantageously has a catwalk with two running surfaces, the running surfaces preferably being aligned horizontally when the device is in the installed state. Advantageously, the body rail has a running surface on a lower surface and a running surface on an upper surface of the walkway, the running surfaces being spaced apart by the thickness of the walkway. The drawer rail preferably has two catwalks. In this case, preferably in the installed state of the device, the horizontally aligned catwalk of the carcass rail is arranged between the catwalks, in particular horizontally aligned catwalks, of the drawer rail. Rolling bodies are preferably arranged between the catwalk of the carcass rail and the catwalks of the drawer rail, so that rolling bodies can be moved along both running surfaces of the catwalk of the carcass rail.

In the case of the drawer rail, preferably on the upper gangway located above the gangway of the carcass rail, only rolling elements are provided along the lower surface or running surface, which is aligned with the gangway of the carcass rail, and on the lower gangway located below the catwalk of the carcass rail, only rolling elements along the upper surface or Running surface, which is aligned with the catwalk of the body rail, movable along. Preferably, the rolling elements, which between the catwalk of the body rail and the Catwalks of the drawer rail are arranged on a carriage so that all rolling elements are moved simultaneously in the opening or closing direction along the running surfaces of the catwalks of the drawer rail and body rail. It is also conceivable that the rolling bodies are arranged on several carriages, with the movement of two or more carriages being able to be synchronized, for example.

Advantageously, the catwalks or the running surfaces of the cabinet rail and drawer rail are designed to be uninterrupted. This means, for example, that there are no gaps or gaps in the catwalk or tread. This has the advantage that the rolling bodies can be moved along the entire running surfaces of the body rail and drawer rail and that the drawer rail runs smoothly in the opening and closing direction.

The two catwalks or running surfaces of the drawer rail are preferably flat. Advantageously, the running surface or running surfaces of the drawer rail are aligned horizontally when the device is mounted on the piece of furniture. A longitudinal extension of the tread preferably runs along the opening and closing direction and a width extension is aligned perpendicularly to the longitudinal extension, with the longitudinal extension and width extension of the tread preferably lying in one plane.

The core of the invention is that the longitudinal extent of the running surface of the body rail is divided into two running sections, with the running sections of the running surface merging into one another without a step, with a plane of a first running section being aligned obliquely with respect to the longitudinal extent relative to a plane of a second running section and not tilted in terms of latitude.

The running surfaces of the rails lie in one plane, the running surfaces being bounded by four edges, two edges running along a width and two edges running along a length. Where the tread has two tread portions, the first and second tread portions each lie in a plane also bounded by four edges, with a fourth edge running within the tread, preferably along a width.

The second running section of the running surface of the cabinet rail preferably has a single plane, with the longitudinal extension of the plane of the cabinet rail advantageously being aligned parallel to the longitudinal extension of the running surface or running surfaces of the drawer rail. Advantageously, the longitudinal extensions of a plane each have the same length and run parallel to one another, so that the longitudinal extensions of a plane are the same. When the device is mounted on the piece of furniture, the longitudinal extensions of the running surfaces of the drawer rail and the longitudinal extension of the second running section of the running surface of the cabinet rail are preferably aligned horizontally.

It is advantageous if the first running section of the running surface of the carcass rail has a single plane. The plane of the second running section of the running surface of the carcass rail preferably transitions smoothly into the plane of the first running section of the running surface of the carcass rail or the planes adjoin one another. The plane of the first running section of the running surface of the carcass rail is preferably aligned obliquely or transversely with respect to the longitudinal extension relative to the plane of the second running section of the running surface of the carcass rail. The longitudinal extent of the plane of the first running section of the running surface of the carcass rail is preferably aligned transversely to a horizontal and vertical when the device is mounted on the piece of furniture. The longitudinal extent of the plane of the first running section of the running surface of the carcass rail preferably runs obliquely upwards, starting from the Level of the second running section of the running surface of the cabinet rail in the direction of the running surface of the drawer rail located above the cabinet rail. The included angle between a longitudinal extent of the first running section of the running surface of the carcass rail and a longitudinal extent of the second running section of the running surface of the carcass rail is preferably greater than 170° and smaller than 180°.

Furthermore, the width extension of the plane of the first running section of the running surface of the carcass rail and the width extension of the plane of the second running section of the running surface of the carcass rail run the same or parallel to one another. Thus, the carriage or the rolling bodies in the carriage are advantageously not tilted in width when moving along the running surface of the carcass rail or along the running sections of the running surface of the carcass rail.

Furthermore, the first running section of the running surface of the carcass rail can also have several levels, with at least one plane of the first running section of the running surface of the carcass rail being aligned obliquely to the planes of the second running section of the running surface of the carcass rail with regard to the longitudinal extension. The planes of the first running section of the running surface of the carcass rail preferably merge into one another without a step. It is conceivable that the first running section of the running surface of the carcass rail has a curved shape. The first running section is preferably designed in such a way that a cross section along the longitudinal extension of the first running section is designed in a curved shape. The first running section can have an incline in the direction of the upper catwalk of the drawer rail or along the course of the first running section directly after the second running section. With both options, the first running section advantageously ends in the assembled state of the device vertically spaced from the second run portion toward the top runway of the drawer slide.

In this case, the width extensions of the different planes of the first running section of the running surface of the carcass rail are preferably aligned parallel to one another and are not tilted in relation to one another. The longitudinal extensions of the different planes of the first running section of the running surface of the carcass rail are aligned, for example, at an angle to one another.

When the drawer rail is moved in the opening direction, the rolling bodies are preferably moved along the running surface of the cabinet rail, with the rolling bodies moving from the second running section to the first running section. If the rolling elements are located on the second running section of the running surface of the cabinet rail, the running surface of the cabinet rail is advantageously aligned parallel to the running surface of the drawer rail. The running surfaces of the drawer rail are preferably aligned horizontally when the rolling elements are located on the second running section of the running surface of the cabinet rail when the device is mounted on the piece of furniture. If the rolling elements reach the first running section of the running surface of the carcass rail, the running surfaces or the catwalks of the drawer rail are aligned obliquely upwards relative to the longitudinal extent of the plane of the second running section of the carcass rail. Thus, the catwalks of the drawer rail are aligned at an angle or at right angles to the horizontal and vertical. By tilting the catwalks of the drawer rail when the drawer rail or the movable furniture part is open or pulled out, a lowering of the movable furniture part, in particular a fully loaded movable furniture part, can advantageously be compensated. Because with standard devices for guiding a movable furniture part, the movable furniture part or the drawer rail when open is caused by the weight of the movable furniture part or the content of the movable furniture part, deflected downwards in the direction of the body rail or at an angle to a horizontal one. Due to the oblique orientation of the runners of the drawer rail, the runners or running surfaces of the drawer rail are pressed or deflected into an approximately horizontal position by the weight of the movable furniture part. As a result, in contrast to the standard devices, the movable furniture part, in particular a heavy movable furniture part, can advantageously be closed without great effort.

A further advantageous variant is based on a device for guiding a movable furniture part, in particular a drawer, which can be slidably accommodated on a furniture body by means of the device, the device comprising a body rail, a drawer rail and a middle rail, the middle rail between the body rail and drawer rail is arranged, wherein the carcass rail can be arranged on the furniture carcass, the displaceably mounted drawer rail and center rail being movable relative to the carcass rail in the opening and closing direction, the carcass rail, center rail and drawer rail each having at least one flat running surface, the running surface of the drawer rail remaining the same throughout is flat, with the movement of the drawer rail and/or center rail relative to the carcass rail, load-transmitting rolling elements being movable along the running surfaces of the rails, with the running surface extending in a longitudinal extension and width extension, with the longitudinal extension being formed perpendicularly to the width extension, with the longitudinal extension of the The running surface of the rails is aligned in the opening and closing direction of the drawer rail, with the longitudinal extent of the running surface of the cabinet rail and/or center rail being divided into two running sections, with the running sections of the running surface merging into one another without a step, with a plane of a first running section relative to a plane of a second run section obliquely with respect to the longitudinal extension is aligned and is not tilted with respect to the width dimension.

This variant of the device is preferably a full extension for the movement of the movable furniture part relative to the furniture body. The device has a body rail, a middle rail and a drawer rail, with both the middle rail and the drawer rail being moved relative to the body rail when the movable furniture part is moved in the opening and closing direction. Furthermore, the drawer rail can preferably also be moved relative to the middle rail during the opening and closing movement of the movable furniture part. The body rail is preferably mounted on the furniture body of the piece of furniture and the movable furniture part is preferably connected to the drawer rail. The middle rail is preferably arranged between the drawer rail and the cabinet rail.

The carcass rail advantageously has a catwalk with two running surfaces, the running surfaces preferably being aligned horizontally when the device is in the installed state. Advantageously, the body rail has a running surface on a lower surface and a running surface on an upper surface of the walkway, the running surfaces being spaced apart by the thickness of the walkway. The center rail preferably has two catwalks. In this case, preferably in the assembled state of the device, the horizontally aligned catwalk of the body rail is arranged between the catwalks, in particular horizontally aligned catwalks, of the center rail.

Rolling bodies are preferably arranged between the catwalk of the body rail and the catwalks of the center rail, so that rolling bodies can be moved along both running surfaces of the catwalk of the carcass rail. At the center rail are preferably on the one above the catwalk the body rail located upper runway rolling elements along the lower surface or running surface, which is aligned with the runway of the body rail and on the lower runway located below the runway of the body rail rolling elements along the upper surface or running surface, which is aligned with the runway of the body rail movable. The running surfaces of the body rail and center rail are preferably vertically spaced in the assembled state of the device, the vertical spacing advantageously being predetermined by the diameter or thickness of the rolling elements. The rolling elements, which are arranged between the gangway of the body rail and the gangways of the central rail, are preferably arranged on a carriage, so that all the rolling elements on the carriage are moved simultaneously and together in the opening or closing direction along the running surfaces of the gangways.

The upper runway or the runway of the center rail arranged above the runway of the carcass rail preferably has two running surfaces, with the upper running surface being aligned in the direction of a running surface of the drawer rail. Further rolling bodies are preferably arranged between the upper running surface of the middle rail and the running surface of the drawer rail. The rolling elements which are arranged between the running surface of the center rail and the cabinet rail are preferably arranged on a carriage and the rolling elements between the running surface of the center rail and the running surface of the drawer rail are arranged on a further carriage.

Preferably, only the longitudinal extent of the running surface of the body rail, only the longitudinal extent of the running surface of the center rail or the longitudinal extent of the running surface of the body rail and the center rail can have two running sections. In this case, a plane of the first running section is preferably aligned obliquely relative to the plane of the second running section with regard to the longitudinal extension. Advantageously, at least the tread of the upper Catwalk of the middle rail on two running section, wherein a plane of the first running section is aligned relative to the plane of the second running section obliquely with respect to the longitudinal extent. It is also conceivable that the running surface of the upper gangway and the running surface of the lower gangway of the middle rail have two running sections, one plane of the first running section being aligned obliquely relative to the plane of the second running section with respect to the longitudinal extent.

The second running section of the running surface of the cabinet rail and/or center rail preferably has a single plane, with the longitudinal extent of the plane of the cabinet rail and/or center rail advantageously being aligned parallel to the longitudinal extent of the plane of the running surface or running surfaces of the drawer rail. When the device is mounted on the piece of furniture, the longitudinal extension of the running surfaces of the drawer rail and the longitudinal extension of the plane of the second running section of the running surface of the cabinet rail and/or middle rail are preferably aligned horizontally.

It is advantageous if the first running section of the running surface of the body rail and/or center rail has a single plane. The plane of the second running section of the running surface of the carcass rail preferably merges seamlessly into the plane of the first running section of the running surface of the carcass rail. Furthermore, the plane of the second running section of the running surface of the middle rail preferably merges seamlessly into the plane of the first running section of the running surface of the middle rail.

The plane of the first running section of the running surface of the carcass rail is preferably aligned obliquely or transversely with respect to the longitudinal extent relative to the plane of the second running section of the running surface of the carcass rail. Preferably, the plane of the first race of the running surface of the center rail is relative to the plane of the second race of the Running surface of the center rail aligned obliquely or transversely with respect to the longitudinal extent. The longitudinal extent of the plane of the first running section of the running surface of the carcass rail and/or center rail is preferably aligned transversely to a horizontal and vertical line when the device is mounted on the piece of furniture. The longitudinal extent of the plane of the first running section of the running surface of the body rail preferably runs obliquely upwards, starting from the plane of the second running section of the running surface of the body rail in the direction of the running surface of the middle rail located above the body rail. Furthermore, the longitudinal extent of the plane of the first running section of the running surface of the center rail preferably runs obliquely upwards, starting from the plane of the second running section of the running surface of the center rail in the direction of the running surface of the drawer rail located above the center rail. In this case, for example, the included angle between a longitudinal extent of the first running section of the running surface of the center rail and a longitudinal extent of the second running section of the running surface of the center rail is greater than 170° and smaller than 180°.

Furthermore, the width extension of the plane of the first running section of the running surface of the middle rail and the width extension of the plane of the second running section of the running surface of the middle rail run the same or parallel to one another. Thus, advantageously, the carriage or the rolling elements in the carriage are not tilted in width when moving along the running surface of the center rail or along the running sections of the running surface of the center rail.

Furthermore, the first running section of the running surface of the center rail can also have several levels, with at least one plane of the first running section of the running surface of the center rail being inclined to the plane of the second running section of the running surface of the center rail with regard to the longitudinal extension is aligned. The planes of the first running section of the running surface of the middle rail preferably merge into one another without a step.

It is conceivable that the first running section of the running surface of the center rail has a curved shape. The first running section is preferably designed in such a way that a cross section along the longitudinal extension of the first running section is designed in a curved shape. The first running section can have an incline in the direction of the upper catwalk of the drawer rail or along the course of the first running section directly after the second running section. In both options, the first running section advantageously ends in the assembled state of the device at a vertical distance from the second running section in the direction of the upper catwalk of the drawer rail. In this case, the width extensions of the different planes of the first running section of the running surface of the center rail are preferably aligned parallel to one another. The longitudinal extensions of the different planes of the first running section of the running surface of the center rail are aligned, for example, at an angle to one another.

During the movement of the movable furniture part in the opening direction, the middle rail is moved relative to the body rail and the drawer rail is moved relative to the body rail and middle rail.

One variant is that only the running surface of the carcass rail has two running sections, the longitudinal extension of the plane of the first running section of the running surface of the carcass rail being aligned obliquely or transversely to the longitudinal extension of the plane of the second running section of the running surface of the carcass rail. Only in the case of the body rail do the rolling bodies, which are arranged between the running surfaces of the middle rail and the running surface of the body rail, pass from the second running section to the first running section of the body rail. The Longitudinal extent of the catwalk or the running surfaces of the center rail are preferably only aligned obliquely upwards relative to the longitudinal extent of the second running section of the body rail when the rolling elements reach the first running section of the running surface of the body rail. Due to the inclined position of the running surface of the middle rail, the catwalk or the running surface of the drawer rail is preferably also aligned at an angle. This is advantageously done just before the completely open position of the movable furniture part is reached, since only then do the rolling elements, which are arranged between the running surfaces of the center rail and the running surface of the carcass rail, reach the first running section of the running surface of the carcass rail. The inclined position of the drawer rail can advantageously compensate for a lowering of the movable furniture part or of the catwalk of the drawer rail on which the movable furniture part rests.

In the event that only the running surface of the center rail has two running sections, the longitudinal extent of the plane of the first running section of the running surface of the center rail being aligned obliquely or transversely to the longitudinal extent of the plane of the second running section of the running surface of the center rail. During the opening movement of the movable furniture part, the longitudinal extension of the second running section of the middle rail remains parallel to the longitudinal extension of the running surface of the carcass rail. If the rolling elements, which are arranged between the running surface of the drawer rail and the upper running surface of the center rail, move from the second running section to the first running section of the center rail, the longitudinal extent of the running surface of the drawer rail is aligned obliquely upwards relative to the longitudinal extent of the second running section of the center rail. This preferably happens just before the completely open position of the movable furniture part is reached.

A further possibility is that both the running surface of the body rail and the running surface of the middle rail each have two running sections. During the movement of the movable furniture part in the opening direction, the rolling elements, which are arranged between the running surfaces of the center rail and the running surface of the carcass rail, reach the first running section of the running surface of the carcass rail, and on the other hand the rolling elements, which are arranged between the upper running surface of the center rail and the running surface of the drawer rail are arranged on the first running section of the upper running surface of the middle rail. Advantageously, the longitudinal extent of the second running section of the running surfaces of the center rail is aligned obliquely relative to the second running section of the body rail, the longitudinal extent of the first running section of the center rail being aligned obliquely to the longitudinal extent of the second running section of the center rail. Furthermore, the catwalk or the running surface of the drawer rail is preferably aligned at an angle relative to the longitudinal extension of the plane of the second running section of the middle rail, with the longitudinal extension of the plane of the second running section of the middle rail already being aligned at an angle relative to the longitudinal extension of the plane of the second running section of the cabinet rail. As a result, the running surface of the drawer rail is aligned more obliquely than if only one rail had two running sections.

It is advantageous that the entire longitudinal extent of the running surface has exactly two running sections.

The running surface of the body rail and/or center rail preferably comprises exactly two running sections, with the plane of the first and the plane of the second running section preferably each having a longitudinal extent. The longitudinal extent of the planes of the first running section and the longitudinal extent of the plane of the second running section together preferably form the entire longitudinal extent of the running surface. Next, the first running section can have multiple levels have, each having a longitudinal extent, then the sum of the longitudinal extent of the planes of the first running section forms the longitudinal extent of the first running section.

It is also advantageous that a longitudinal extension of the first and second running section each have a starting point and an end point, with the starting point of the longitudinal extension of the second running section and the end point of the longitudinal extension of the first running section being formed on an end edge of the tread.

The entire longitudinal extension of the running surface preferably extends from the starting point of the longitudinal extension of the second running section to the end point of the longitudinal extension of the first running section. In the case of the carcass rail mounted on the furniture body in the assembled state, the starting point of the longitudinal extension of the second running section is preferably in the direction of the rear wall of the furniture carcass and the end point of the first longitudinal extension is at the opening of the furniture carcass or at a front area of the side wall of the furniture carcass. In the closed state of the movable furniture part, the end point of the longitudinal extension of the second running section is preferably arranged in the carcass rail in the vicinity of a front of the movable furniture part. Because the center rail is moveable relative to the body rail, the endpoints and start points of the longitudinal extent of the center rail are shifted. The starting point of the longitudinal extension of the second running section of the middle rail is arranged at one end on the running surface in the closing direction and the end point of the longitudinal extension of the first running section of the middle rail is arranged at one end on the running surface in the opening direction.

When the device is mounted on the furniture and the movable furniture part is in the closed state, the starting point of the longitudinal extension of the second running section of the middle rail is also aligned in the direction of the rear wall of the furniture body.

Advantageously, the end point of the longitudinal extension of the second running section corresponds to the starting point of the longitudinal extension of the first running section.

The end point of the longitudinal extent of the second running section or the starting point of the longitudinal extent of the first running section is advantageously located within the running surface. The end point of the longitudinal extension of the second running section or the starting point of the longitudinal extension of the first running section is preferably more than 60%, preferably more than 70%, more than 80%, more than 90% away from the starting point of the longitudinal extension of the second running section.

It is also advantageous that when the device is installed, the first running section is formed on a front end region of the rail in the opening direction of the drawer rail.

When the device is mounted on the piece of furniture, the front end area of the carcass rail is preferably aligned in the direction of the opening of the furniture carcass. In the closed state of the movable furniture part, the front end area of the carcass rail is arranged close to the front of the movable furniture part.

Furthermore, the front end area of the center rail is preferably aligned in the closed state of the movable furniture part in the direction of the opening of the furniture body. The front end area of the middle rail is also aligned in the direction of the movable furniture part, with the front end area of the middle rail being arranged in the vicinity of the front of the movable furniture part, in particular a drawer front of a drawer, when the movable furniture part is in the closed state. During the opening movement of the movable furniture part in the opening direction, due to the relative movement between the drawer rail and the middle rail, the front end area of the middle rail further and further away from the front of the movable furniture part.

It is advantageous that the longitudinal extent of the second running section of the rail extends over 60% to 90% of the entire longitudinal extent of the running surface of the rail.

The longitudinal extent of the second running section advantageously extends over 60%, over 65%, over 70%, over 75%, over 80%, over 85% of the entire longitudinal extent of the running surface of the body rail and/or center rail.

The longitudinal extent of the second running section preferably extends from the starting point of the second running section to the end point of the second running section, the starting point of the second running section beginning at a rear end-side edge of the tread.

The rear end edge of the running surface, at which the starting point of the second running section is arranged, is preferably arranged on a central to rear region of the side wall of the furniture body when the device is mounted on the furniture rail. The rear end edge of the body rail is preferably aligned in the direction of the rear wall of the furniture body and transverse to the direction of movement of the center rail and/or drawer rail.

In the middle rail, the rear end edge of the running surface, on which the starting point of the second running section is arranged, is arranged in the closed state of the movable furniture part on a rear area of the side wall of the furniture body, with the rear area of the side wall of the furniture body being connected to the rear wall of the furniture body connected is. The rear end edge of the running surface of the center rail is moved along the body rail during the opening movement of the movable furniture part, whereby the rear end edge of the running surface of the center rail in the complete open state of the movable furniture part is preferably positioned in the central region of the running surface of the carcass rail.

A further advantageous possibility results from the fact that the longitudinal extent of the first running section of the rail extends over 10% to 40% of the entire longitudinal extent of the running surface of the rail.

The longitudinal extent of the first running section advantageously extends over 10%, over 15%, over 20%, over 25%, over 30%, over 35% of the entire longitudinal extent of the running surface of the body rail and/or middle rail.

Preferably, the longitudinal extent of the first running section extends from the starting point of the first running section to the end point of the first running section, the end point of the first running section being arranged at a front-end edge of the tread.

The front end edge of the running surface, on which the end point of the first running section is arranged, is preferably arranged on the carcass rail in a front area of the side wall of the furniture carcass when the device is mounted on the furniture, with the front area of the side wall of the furniture carcass opening to the Furniture body is aligned.

In the middle rail, the front end edge of the running surface, which has the end point of the first running section, is arranged above the front end edge of the running surface of the carcass rail in the closed state of the movable furniture part. The front end edge of the running surface of the middle rail is moved along the body rail during the opening movement of the movable furniture part, whereby the front end edge of the running surface of the middle rail when the movable furniture part is completely open is preferably in the middle area of the running surface of the Drawer rail comes to a halt or is spaced from the running surface of the cabinet rail.

It is also advantageous that when the device is assembled, the longitudinal extension of the second running section is aligned horizontally.

In the assembled state, the carcass rail is connected to a side wall of the furniture carcass, with the catwalk or the longitudinal extensions of the running surfaces of the rails being aligned horizontally. In the case of the rails in which the running surfaces have two running sections, only the longitudinal extent of the second running section of the running surface is advantageously aligned horizontally. The longitudinal extent of the first running section of the rails with two running sections is preferably aligned obliquely to the horizontal and vertical in the assembled state.

Advantageously, in the assembled state of the device, the end point of the longitudinal extent of the first running section and the end point of the longitudinal extent of the second running section are vertically spaced from one another.

The vertical distance or the difference in height between the end point of the longitudinal extent of the second running section and the end point of the longitudinal extent of the first running section is preferably 0.2-2 mm. The end point of the longitudinal extent of the first running section is advantageously closer in the direction of the movable furniture part than the end point of the longitudinal extent of the second running section.

The vertical distance or the height difference between the starting point and the end point of the longitudinal extension of the first running section is preferably 0.2 to 2 mm.

Preferably, due to the inclination of the plane of the first running section relative to the second plane Running section reaches the height difference, whereby a lowering of the movable furniture part in the open state of the movable furniture part can be counteracted.

An advantageous embodiment of the invention is a piece of furniture with a movable furniture part, which can be moved relative to the furniture body in the opening and closing direction with a device according to one of the previously described embodiments.

The second carriage 33 preferably also includes lateral support bodies 38, the lateral support bodies 38 being arranged, for example, between the side gangways 39 of the center rail 11 and the side gangways 40 of the drawer rail 12. The carriage 33 is also moved, for example, in a supporting manner along the running surfaces 36, 37 or the side running surfaces 39, 40 of the center rail 11 and the drawer rail 12.

In the figure 4 and 5 the body rail 10 is shown in different views. The body rail 10 is designed in one piece, for example, as a bent sheet metal part. The carcass rail 10 comprises a mounting strip 41, an underbody 42, the side catwalk 29 and the catwalk 18. Using the mounting strip 41, the carcass rail 10 can be attached to the side wall 8, 9 of the furniture carcass 2 using fastening means such as screws. The underbody 42, the side gangway 29 and the gangway 18 preferably form a U-shape, with the underbody 42 connecting the mounting bar 41 and the side gangway 29 together. The U-shape is preferably open towards the mounting bar 41. The side tread 29 preferably connects the tread 18 and the underbody 42.

As in figure 4 and 5 shown, the running surface 25 of the carcass rail 10 advantageously has two running sections 43, 44. The running sections 43, 44 preferably each form a plane, the planes of the running sections 43, 44 having a longitudinal extension L1, L2 and a width extension. The longitudinal extension L1 of a first running section 43 extends from a starting point 45 to an end point 46, with the end point 46 preferably ending at a front end-side edge 47 of the running surface 25 of the body rail 10. The longitudinal extent L2 of a second running section 44 extends from a starting point 48 to an end point 49, the starting point 48 beginning at a rear end-side edge 50 of the running surface 25 of the carcass rail 10. The front end edge 47 of the running surface 25 of the carcass rail 10 is arranged in the mounted state of the carcass rail 10 on the side wall 8, 9 of the furniture body 2 in the vicinity of the opening 52 of the furniture body 2. When the drawer 3 is closed, the front end edge 47 of the running surface 25 of the carcass rail 10 is in the vicinity of the drawer front 16.

Since the first running section 43 merges seamlessly into the second running section 44, for example, the end point 49 of the longitudinal extent L2 of the second running section 44 corresponds to that Starting point 45 of the longitudinal extent L1 of the first running section 43.

Preferably, the longitudinal extent L1 of the plane of the first running section 43 is oriented obliquely relative to the longitudinal extent L2 of the plane of the second running section 44 . The width extensions of the planes of the first and second barrel sections 43, 44 run perpendicular to the longitudinal extension of the planes of the first and second barrel sections 43, 44, with the width extension of the first barrel section 43 running parallel to the width extension of the second barrel section 44. The width extensions of the two running sections 43, 44 are preferably not tilted relative to one another. The angle α, which is enclosed between the longitudinal extension of the first running section and the longitudinal extension of the second running section, is preferably less than 180° and more than 170°.

The longitudinal extent L2 of the plane of the second running section 44 is preferably aligned horizontally when the carcass rail 10 is installed on the side wall 8, 9 of the furniture carcass 2, with the longitudinal extent L1 of the plane of the first running section 43 being aligned transversely to a horizontal or vertical line. The end point 46 of the longitudinal extent L1 of the first running section 43 and the end point 49 of the longitudinal extent L2 of the second running section 44 are advantageously vertically spaced from one another or have a height difference (see Fig. figure 5 ). This height difference advantageously contributes to compensating for the lowering of the drawer 3 in the open state. The entire longitudinal extent of the running surface 25 comprises the longitudinal extent L1 of the first running section 43 and the longitudinal extent L2 of the second running section 44, with the longitudinal extent L1 of the first running section 43 being 10% to 40% of the entire longitudinal extent of the running surface 25 of the carcass rail 10.

In the Figures 6 to 8 is the device 4 in the different states during the movement of the drawer 3 in Opening direction shown. In figure 6 is the closed state, in figure 7 half pulled out condition and in figure 8 the fully extended or fully open state is shown. Both Figures 6 to 8 only the cabinet rail 10 has two running sections 43, 44.

When the drawer 3 is closed, the 3 rails 10, 11, 12 are on top of each other (see Fig. 6 ), A rear end of the running surfaces 22, 26, 36, 37 of the center rail 11 and the drawer rail 12 preferably protruding over the second running section 44 of the running surface 25 of the cabinet rail 10. When the body rail 10 is mounted on the side wall 8, 9 of the furniture body 2, for example, the rear ends of the running surfaces 22, 26, 36, 37 of the center rail 11 and the drawer rail 12 are in the vicinity of the rear wall 7 of the furniture body 2. The first running section 43 of the Running surface 25 of the cabinet rail 10 is preferably arranged in the vicinity of the opening 52 of the furniture body 2 in the assembled state, with the front ends of the running surfaces 22, 26, 36, 37 of the drawer rail 12 and the center rail 11 also being preferably in the vicinity when the drawer 3 is closed the opening 52 of the furniture body 2 are arranged. Since the upper surface of the drawer rail 12 is connected, for example, to the drawer bottom 13 in the assembled state, the front end of the catwalk 35 of the drawer rail 12 and thus also the running surface 37 of the drawer rail 12 is preferably located on the drawer front 16 and the rear end of the catwalk 35 on the Drawer rail 12 on the drawer rear wall 17 during the opening and closing movement of the drawer 3.

When the drawer 3 is closed, the carriages 27, 33 are arranged, for example, centrally on the rails 10, 11, 12 or running surfaces 22, 23, 25, 26, 36, 37 of the rails 10, 11, 12. Thus, the carriage 27, in which the rolling elements 21, 24 are arranged between the catwalk 18 of the body rail 10 and the catwalks 19, 20 of the center rail 11 is preferably on the second running section 44 of the running surface 25 of the cabinet rail 10. The longitudinal extensions of the catwalks 19, 20, 35 or the running surfaces 22, 26, 36, 37 of the center rail 11 and drawer rail 12 are preferably aligned parallel to the longitudinal extension L2 of the second running section 44 of the cabinet rail 10. This means that when the carcass rail 10 is installed on the side wall 8, 9 of the furniture carcass 2, the longitudinal extents of the running surfaces 22, 26, 36, 37 of the center rail 11 and drawer rail 12, as well as the longitudinal extent L2 of the second running section 44 of the carcass rail 10, are preferably horizontal are aligned.

If the drawer 3 is now moved from a closed position in the opening direction P1, for example the middle rail 11 is moved relative to the cabinet rail 10 and the drawer rail 12 is moved relative to the center rail 11 and cabinet rail 10 (see Fig. 7 ). The carriages 27, 33 are moved along the running surfaces 22, 23, 25, 26, 36, 37 of the rails 10, 11, 12, with the carriage 27, in which the rolling elements 21, 24 between the runway 18 of the carcass rail 10 and the catwalks 19, 20 of the center rail 11 hardly moves in the opening direction P1. This means that preferably the carriage 27 can also be used in the half-extended state (see Fig. 7 ) is still on the second running section 44 of the cabinet rail 10 and thus the running surfaces 22, 26, 36, 37 of the drawer rail 12 and middle rail 11 are still aligned horizontally. The carriage 33, in which the rolling elements 34 are arranged between the catwalk 20 of the middle rail 11 and the catwalk 35 of the drawer rail 12, is in the half-extended state approximately halfway along the catwalk 20 of the middle rail 11 and approximately in the front half of the catwalk 18 of the carcass rail 10. The front half of the catwalk 18 of the carcass rail 10 is preferably the half of the catwalk 18 which is aligned in the direction of the opening 52 of the furniture carcass 2.

With the further opening movement of the drawer 3 or the middle rail 11 and drawer rail 12 in the opening direction P1 When the carriage 27 reaches the rear end of the center rail 11 during the relative movement between the center rail 11 and the cabinet rail 10, there is a limit (not shown) for the carriage 27 at the rear end of a side catwalk 39 of the center rail 11, so that the carriage 27 at the rear end of the center rail 11 can be moved in the opening direction P1 by the limitation with the center rail 11 . The carriage 27 preferably reaches a stop 51 (see Fig. 4 ) at the front end of the body rail 10, so that the carriage 27 can no longer be moved in the opening direction P1.

The carriage 33 is also preferably moved to the rear end of the drawer rail 12 during the relative movement between the center rail 11 and the drawer rail 12 . For example, there is a limit (not shown) for the carriage 33 at the rear end of a side walkway 40 of the drawer rail 12, so that the carriage 27 at the rear end of the drawer rail 11 can be moved in the opening direction P1 with the drawer rail 11 through the limit.

The carriage 27 or the rolling elements 24 are located when the drawer 3 is fully open (see Fig. 8 ) preferably between the stop 51 of the body rail 10 and the boundary of the center rail 11, so that the rolling elements 24 are now on the first running section 43 of the body rail 10. As a result, the carriage 27 and thus also the longitudinal extent of the running surface of the center rail 11 are preferably aligned obliquely upwards or obliquely to a horizontal or vertical line. This means that the longitudinal extent of the running surface 22 , 26 , 36 of the center rail 11 is aligned at an angle relative to the longitudinal extent L2 of the second running section 44 of the body rail 10 . Due to the inclined position of the running surfaces 22, 26, 36 of the middle rail 11, the running surface 37 of the drawer rail 12 is also aligned obliquely upwards, with the longitudinal extent of the running surface 22, 26, 36 of the middle rail 11 and the longitudinal extent of the running surface 37 of the drawer rail 12 run approximately parallel.
