[0002] There are known devices with guide rails for guiding movable furniture parts, in which, in the open state of the movable furniture part, the lowering of the movable furniture part relative to the furniture body is compensated.

[0003] In the known devices, the diameter or material of the rolling elements moving along the running surface of the device guide rail in the carriage is changed. Summary of the Invention

[0004] Object and Advantages of the Invention

[0005] The object of the present invention is to provide an improved device for guiding a movable furniture part relative to a furniture body, which is improved especially in terms of the compactness and simplicity of its structure.

[0006] This object is achieved by the features of the independent claims.

[0007] Advantageous, convenient embodiments, variants and expansion schemes of the present invention are presented in the dependent claims.

[0008] The present invention starts from a device for guiding a movable furniture part, especially a drawer, which can be movably received on a furniture body by means of the device, wherein the device includes a body guide rail and a drawer guide rail, wherein the body guide rail can be arranged on the furniture body, wherein the movably mounted drawer guide rail can move relative to the body guide rail in the opening and closing directions, wherein each of the body guide rail and the drawer guide rail has at least one flat running surface, wherein the running surface of the drawer guide rail is continuously and uniformly flat, wherein, during the relative movement between the drawer guide rail and the body guide rail, load-transferring rolling elements can move along the running surfaces of the body guide rail and the drawer guide rail, wherein the running surface extends in a longitudinal range and a transverse range, wherein the longitudinal range is designed to be perpendicular to the transverse range, and wherein the longitudinal range of the running surface is oriented in the opening and closing directions of the drawer guide rail.

[0009] The device is preferably a drawer pull-out guide, in particular a partially extended slide rail. The furniture preferably has two identical devices, and in any case, one device is provided between the side wall of the furniture body and the side wall of the movable furniture part. In the installed state, the body guide rail is preferably fixed to the furniture body and the drawer guide rail is preferably fixed to the movable furniture part. Advantageously, the drawer guide rail on which the movable furniture part is arranged can move linearly relative to the body guide rail at a fixed position, for example, arranged on the side wall of the furniture body, and the drawer guide rail can move relative to the body guide rail in the opening and closing directions.

[0010] The movable furniture part preferably rests on the running web of the drawer guide rail, in particular on the surface of the running web of the drawer guide rail, which is horizontally or at least almost horizontally oriented in the installed state of the device. The movable furniture part preferably rests on the upper surface of the running web of the drawer guide rail, and the rolling elements can preferably move along the lower surface of the running web of the drawer guide rail. The upper surface and the lower surface are preferably arranged opposite each other on the running web and are separated from each other by the material thickness of the running web of the drawer guide rail. The lower surface of the running web of the drawer guide rail preferably forms the running surface.

[0011] Advantageously, rolling elements such as balls or rollers are arranged between the lower surface or the running surface of the drawer guide rail and the running surface of the body guide rail.

[0012] The body guide rail advantageously has a running web including two running surfaces, and the running surfaces are preferably horizontally oriented in the installed state of the device. Advantageously, one running surface of the body guide rail is located on the lower surface of the running web, and one running surface is located on the upper surface of the running web, and the running surfaces are spaced apart by the thickness of the running web. The drawer guide rail preferably has two running webs. In this case, preferably in the installed state of the device, the horizontally oriented running web of the body guide rail is arranged between the running webs of the drawer guide rail, especially the horizontally oriented running webs. Each rolling element is preferably arranged between the running web of the body guide rail and the running web of the drawer guide rail, so that the rolling element can move along the two running surfaces of the running web of the body guide rail.

[0013] In the case of drawer guides, preferably on the upper running surface located above the running web of the body guide, the rolling elements can only move along the lower surface or running surface oriented towards the running web of the body conductor, while on the lower running surface located below the running web of the body guide, the rolling elements can only move along the upper surface or running surface oriented towards the running web of the body guide. The rolling elements arranged between the running web of the body guide and the running web of the drawer guide are preferably arranged on a carriage such that all the rolling elements can move simultaneously along the running surfaces of the running webs of the drawer guide and the body guide in the opening and closing directions. Additionally, it is conceivable to arrange the rolling elements on multiple carriages, where the movement of, for example, two or more carriages can be synchronized.

[0014] The running webs or running surfaces of the body guide and the drawer guide are advantageously designed to be uninterrupted. For example, this means that there are no spaces or gaps in the running webs or running surfaces. The advantage of this is that the rolling elements can move along the entire running surface of the body guide and the drawer guide, ensuring smooth operation of the drawer guide in the opening and closing directions.

[0015] The two running webs or running surfaces of the drawer guide are preferably designed to be flat. Advantageously, one or more running surfaces of the drawer guide are horizontally oriented in the state where the device is installed on furniture. Preferably, the longitudinal extent of the running surface extends along the opening and closing directions, and the transverse extent is oriented perpendicular to the longitudinal extent, where the longitudinal extent and the transverse extent of the running surface are preferably located in a plane.

[0016] The key to the present invention is that the longitudinal extent of the running surface of the body guide is divided into two running sections, where the running sections of the running surface meet each other without offset, and where, relative to the plane of the second running section, the plane of the first running section is aligned obliquely with respect to the longitudinal extent and not obliquely with respect to the transverse extent.

[0017] The running surface of the guide is located in a plane, where the running surface is bounded by four edges, where two edges extend along the width and two edges extend along the length. If the running surface has two running sections, then the first and second running sections are each located in a plane also bounded by four edges, where the fourth edge preferably extends along the width within the running surface.

[0018] The second running section of the running surface of the body guide preferably has a single plane, wherein the longitudinal extent of the plane of the body guide is advantageously oriented parallel to the longitudinal extent of one or more running surfaces of the drawer guide. Advantageously, the longitudinal extents of the planes each have the same length and extend parallel to each other, thus ensuring that the longitudinal extents of the planes are the same. In the state where the device is installed on the furniture, the longitudinal extent of the running surface of the drawer guide and the longitudinal extent of the second running section of the running surface of the body guide are preferably oriented horizontally.

[0019] Advantageously, the first running section of the running surface of the body guide has a single plane. The plane of the second running section of the running surface of the body guide preferably merges into the plane of the first running section of the running surface of the body guide without offset, or these planes are adjacent to each other. In this case, the plane of the first running section of the running surface of the body guide is preferably oriented obliquely or transversely with respect to the plane of the second running section of the running surface of the body guide with respect to the longitudinal extent. In the state where the device is installed on the furniture, the longitudinal extent of the plane of the first running section of the running surface of the body guide is preferably oriented transversely with respect to the horizontal direction and the vertical direction. The longitudinal extent of the plane of the first running section of the running surface of the body guide preferably extends obliquely upward in the direction of the running surface of the drawer guide located above the body guide starting from the plane of the second running section of the running surface of the body guide. In this case, the angle between the longitudinal extent of the first running section of the running surface of the body guide and the longitudinal extent of the second running section of the running surface of the body guide is preferably greater than 170° and less than 180°.

[0020] Furthermore, the lateral extent of the plane of the first running section of the running surface of the body guide and the lateral extent of the plane of the second running section of the running surface of the body guide extend in the same direction or parallel to each other. When moving along the running surface of the body guide or along the running section of the running surface of the body guide, the rollers in the carriage or the carriage are thus advantageously not tilted in the lateral extent.

[0021] In addition, the first running section of the running surface of the body guide rail may also have a plurality of planes, wherein at least one plane of the first running section of the running surface of the body guide rail is inclined relative to the longitudinal extent with respect to the second running section of the running surface of the body guide rail. The planes of the first running section of the running surface of the body guide rail preferably meet each other without offset. It is conceivable that the first running section of the running surface of the body guide rail has a curved shape. The first running section is preferably configured such that the cross-section along the longitudinal extent of the first running section is configured in a curved shape. In this case, the first running section may have an inclination in the direction of the upper running web of the drawer guide rail or along the course of the first running section immediately after the second running section. For both possibilities, in the installed state of the device, the first running section advantageously terminates at a certain vertical distance from the second running section in the direction of the upper running web of the drawer guide rail.

[0022] In this case, the lateral extents of the different planes of the first running section of the running surface of the body guide rail are preferably oriented parallel to each other or not inclined relative to each other. The longitudinal extents of the different planes of the first running section of the running surface of the body guide rail are, for example, oriented inclined relative to each other.

[0023] As the drawer guide rail moves in the opening direction, the rolling elements preferably move along the running surface of the body guide rail, and the rolling elements move from the second running section to the first running section. When the rolling elements are located on the second running section of the running surface of the body guide rail, the running surface of the body guide rail is advantageously oriented parallel to the running surface of the drawer guide rail. When the rolling elements are located on the second running section of the running surface of the body guide rail, the running surface of the drawer guide rail is preferably oriented horizontally in the state where the device is installed on the furniture. When the rolling elements reach the first running section of the running surface of the body guide rail, the running surface or running web of the drawer guide rail is inclined upward relative to the longitudinal extent of the plane of the second running section of the body guide rail. The running web of the drawer guide rail is thus inclined or transversely oriented with respect to the horizontal direction and the vertical direction. Due to the inclined position of the running web of the drawer guide rail in the open state or extended state of the drawer guide rail or the movable furniture part, it is advantageously possible to compensate for the lowering of the movable furniture part, especially the fully loaded movable furniture part. This is because, in a standard device for guiding a movable furniture part, the movable furniture part or the drawer guide rail in the open state is deflected downward inclined in the direction of the body guide rail or relative to the horizontal direction due to the weight of the movable furniture part or the contents of the movable furniture part. Due to the inclined orientation of the running web of the drawer guide rail, the running web or running surface of the drawer guide rail is pushed or deflected to a substantially horizontal position by the weight of the movable furniture part. As a result, compared to a conventional device, the movable furniture part, especially a heavy movable furniture part, can be closed advantageously with less effort.

[0024] Another advantageous variant starts from a device for guiding a movable furniture part, in particular a drawer, which furniture part can be movably received on a furniture body by means of the device, wherein the device comprises a body guide rail, a drawer guide rail and an intermediate guide rail, wherein the intermediate guide rail is arranged between the body guide rail and the drawer guide rail, wherein the body guide rail can be arranged on the furniture body, wherein the movably mounted drawer guide rail and the intermediate guide rail can move relative to the body guide rail in the opening and closing directions, wherein the body guide rail, the intermediate guide rail and the drawer guide rail each have at least one flat running surface, wherein the running surface of the drawer guide rail is continuously and uniformly flat, wherein, during the movement of the drawer guide rail and / or the intermediate guide rail relative to the body guide rail, load-transmitting rolling elements can move along the running surface of the guide rail, wherein the running surface extends in a longitudinal extent and a transverse extent, wherein the longitudinal extent is designed to be perpendicular to the transverse extent, wherein the longitudinal extent of the running surface of the guide rail is oriented in the opening and closing directions of the drawer guide rail, wherein the longitudinal extent of the running surface of the body guide rail and / or the intermediate guide rail is divided into two running sections, wherein the running sections of the running surface meet each other without offset, wherein, relative to the plane of the second running section, the plane of the first running section is inclined relative to the longitudinal extent and not inclined relative to the transverse extent.

[0025] This variant of the device is preferably a full-extension slide rail for the movement of a movable furniture part relative to a furniture body. Here, the device has a body guide rail, an intermediate guide rail and a drawer guide rail, wherein both the intermediate guide rail and the drawer guide rail move relative to the body guide rail when the movable furniture part moves in the opening and closing directions. In addition, during the opening and closing movement of the movable furniture part, the drawer guide rail can preferably also move relative to the intermediate guide rail. The body guide rail is preferably mounted on the furniture body of the furniture, and the movable furniture part is preferably connected to the drawer guide rail. The intermediate guide rail is preferably arranged between the drawer guide rail and the body guide rail.

[0026] Advantageously, the body guide rail has a running web comprising two running surfaces, wherein the running surfaces are preferably oriented horizontally in the installed state of the device. Advantageously, one running surface of the body guide rail is located on the lower surface of the running web and one running surface is located on the upper surface of the running web, wherein the running surfaces are spaced apart by the thickness of the running web. The intermediate guide rail preferably has two running webs. In this case, preferably in the installed state of the device, the horizontally oriented running web of the body guide rail is arranged between the running webs of the intermediate guide rail, in particular the horizontally oriented running webs.

[0027] Each rolling element is preferably arranged between the running webs of the body guide rail and the intermediate guide rail, so that the rolling element can move along the two running surfaces of the running web of the body guide rail. In the case of the intermediate guide rail, preferably on the upper running surface located above the running web of the body guide rail, the rolling element can move along the lower surface or running surface oriented towards the running web of the body guide rail, and on the lower running web located below the running web of the body guide rail, the rolling element can move along the upper surface or running surface oriented towards the running web of the body guide rail. In this case, the running surfaces of the body guide rail and the central guide rail are preferably vertically spaced apart in the installed state of the device, and the vertical spacing is advantageously predetermined by the diameter or thickness of the rolling element. The rolling elements arranged between the running webs of the body guide rail and the intermediate guide rail are preferably arranged on brackets, so that all the rolling elements can move simultaneously and jointly along the running surfaces of the running webs in the opening or closing direction.

[0028] The upper running web or the running web of the intermediate guide rail arranged above the running web of the body guide rail preferably has two running surfaces, where the upper running surface is oriented towards the running surface of the drawer guide rail. Additional rolling elements are preferably arranged between the upper running surface of the intermediate guide rail and the running surface of the drawer guide rail. As a preferred option, the rolling elements arranged between the running surface of the intermediate guide rail and the body guide rail are arranged on a bracket, and the rolling elements between the running surface of the intermediate guide rail and the running surface of the drawer guide rail are arranged on another bracket.

[0029] As a preferred option, only the longitudinal extent of the running surface of the body guide rail, only the longitudinal extent of the running surface of the intermediate guide rail, or the longitudinal extents of the running surfaces of the body guide rail and the intermediate guide rail can have two running sections. In this case, the plane of the first running section is preferably oriented obliquely with respect to the plane of the second running section in terms of the longitudinal extent. Advantageously, at least the running surface of the upper running web of the intermediate guide rail has two running sections, where the plane of the first running section is oriented obliquely with respect to the plane of the second running section in terms of the longitudinal extent. It is also conceivable that the running surfaces of the upper running web and the lower running web of the intermediate guide rail have two running sections, where in any case one plane of the first running section is oriented obliquely with respect to the plane of the second running section in terms of the longitudinal extent.

[0030] The second running section of the running surface of the body guide rail and / or the intermediate guide rail preferably has a single plane, wherein the longitudinal extent of the plane of the body guide rail and / or the intermediate guide rail is advantageously oriented parallel to the longitudinal extent of the plane of one or more running surfaces of the drawer guide rail. In the state where the device is installed on the furniture, the longitudinal extent of the running surface of the drawer guide rail and the longitudinal extent of the plane of the second running section of the running surface of the body guide rail and / or the intermediate guide rail are preferably oriented horizontally.

[0031] Advantageously, the first running section of the running surface of the body guide rail and / or the intermediate guide rail has a single plane. The plane of the second running section of the running surface of the body guide rail preferably merges into the plane of the first running section of the running surface of the body guide rail without offset. In addition, the plane of the second running section of the running surface of the intermediate guide rail preferably merges into the plane of the first running section of the running surface of the intermediate guide rail without offset.

[0032] In this case, the plane of the first running section of the running surface of the body guide rail is preferably oriented obliquely or transversely with respect to the plane of the second running section of the running surface of the body guide rail with respect to the longitudinal extent. The plane of the first running section of the running surface of the intermediate guide rail is preferably oriented obliquely or transversely with respect to the plane of the second running section of the running surface of the intermediate guide rail with respect to the longitudinal extent. In the state where the device is installed on the furniture, the longitudinal extent of the plane of the first running section of the running surface of the body guide rail and / or the intermediate guide rail is preferably oriented transversely with respect to the horizontal direction and the vertical direction. The longitudinal extent of the plane of the first running section of the running surface of the body guide rail preferably extends obliquely upward in the direction of the running surface of the intermediate guide rail located above the body guide rail starting from the plane of the second running section of the running surface of the body guide rail. In addition, the longitudinal extent of the plane of the first running section of the running surface of the intermediate guide rail preferably extends obliquely upward in the direction of the running surface of the drawer guide rail located above the intermediate guide rail starting from the plane of the second running section of the running surface of the intermediate guide rail. In this case, for example, the angle between the longitudinal extent of the first running section of the running surface of the intermediate guide rail and the longitudinal extent of the second running section of the running surface of the intermediate guide rail is greater than 170° and less than 180°.

[0033] In addition, the lateral extent of the plane of the first running section of the running surface of the intermediate guide rail and the lateral extent of the plane of the second running section of the running surface of the intermediate guide rail extend in the same direction or parallel to each other. The rolling elements in the carriage or the carriage thus advantageously do not tilt in the lateral extent when moving along the running surface of the intermediate guide rail or along the running section of the running surface of the intermediate guide rail.

[0034] Furthermore, the first running section of the running surface of the intermediate guide rail may also have a plurality of planes, wherein at least one plane of the first running section of the running surface of the intermediate guide rail is inclinedly oriented with respect to the plane of the second running section of the running surface of the intermediate guide rail in the longitudinal extent. The planes of the first running section of the running surface of the intermediate guide rail preferably meet each other without offset.

[0035] It is conceivable that the first running section of the running surface of the intermediate guide rail has a curved shape. The first running section is preferably configured such that the cross-section along the longitudinal extent of the first running section is configured in a curved shape. In this case, the first running section may have an inclination in the direction of the upper running web of the drawer guide rail or along the course of the first running section immediately after the second running section. For both possibilities, in the installed state of the device, the first running section advantageously terminates at a certain vertical distance from the second running section in the direction of the upper running web of the drawer guide rail. In this case, the lateral extents of the different planes of the first running section of the running surface of the intermediate guide rail are preferably oriented parallel to each other. The longitudinal extents of the different planes of the first running section of the running surface of the intermediate guide rail are, for example, inclinedly oriented relative to each other.

[0036] During the movement of the movable furniture part in the opening direction, the intermediate guide rail moves relative to the body guide rail, while the drawer guide rail moves relative to the body guide rail and the intermediate guide rail.

[0037] One variant is that only the running surface of the body guide rail has two running sections, wherein the longitudinal extent of the plane of the first running section of the running surface of the body guide rail is inclined or transversely oriented with respect to the longitudinal extent of the plane of the second running section of the running surface of the body guide rail. In this case, only in the case of the body guide rail, the rolling elements arranged between the running surface of the intermediate guide rail and the running surface of the body guide rail move from the second running section of the body guide rail to the first running section of the body guide rail. The longitudinal extent of the running web or the running surface of the intermediate guide rail preferably does not incline upward with respect to the longitudinal extent of the second running section of the body guide rail until the rolling elements reach the first running section of the running surface of the body guide rail. Due to the inclined position of the running surface of the intermediate guide rail, the running web or the running surface of the drawer guide rail is also preferably inclinedly oriented. This advantageously occurs only shortly before the movable furniture part reaches the fully open position, because only then do the rolling elements arranged between the running surface of the intermediate guide rail and the running surface of the body guide rail reach the first running section of the running surface of the body guide rail. Due to the inclined position of the drawer guide rail, the lowering of the movable furniture part of the drawer guide rail or the running web on which the movable furniture part rests can be advantageously compensated for.

[0038] In the case where only the running surface of the intermediate guide rail has two running sections, the longitudinal extent of the plane of the first running section of the running surface of the intermediate guide rail is oriented obliquely or transversely with respect to the longitudinal extent of the plane of the second running section of the running surface of the intermediate guide rail. During the opening movement of the movable furniture part, the longitudinal extent of the second running section of the intermediate guide rail remains parallel to the longitudinal extent of the running surface of the body guide rail. When the rolling elements arranged between the running surface of the drawer guide rail and the upper running surface of the intermediate guide rail move from the second running section of the intermediate guide rail to the first running section of the intermediate guide rail, the longitudinal extent of the running surface of the drawer guide rail is oriented obliquely upward with respect to the longitudinal extent of the second running section of the intermediate guide rail. This preferably occurs only shortly before the movable furniture part reaches the fully open position.

[0039] Another possibility is that both the running surface of the body guide rail and the running surface of the intermediate guide rail have two running sections. During the movement of the movable furniture part in the opening direction, on the one hand, the rolling elements arranged between the running surface of the intermediate guide rail and the running surface of the body guide rail move onto the first running section of the running surface of the body guide rail, and on the other hand, the rolling elements arranged between the upper running surface of the intermediate guide rail and the running surface of the drawer guide rail move onto the first running section of the upper running surface of the intermediate guide rail. In this case, the longitudinal extent of the second running section of the running surface of the intermediate guide rail is advantageously oriented obliquely with respect to the second running section of the body guide rail, wherein the longitudinal extent of the first running section of the intermediate guide rail is oriented obliquely with respect to the longitudinal extent of the second running section of the intermediate guide rail. In addition, the running web or running surface of the drawer guide rail is preferably oriented obliquely with respect to the longitudinal extent of the plane of the second running section of the intermediate guide rail, wherein the longitudinal extent of the plane of the second running section of the intermediate guide rail is already oriented obliquely with respect to the longitudinal extent of the plane of the second running section of the body guide rail. As a result, the running surface of the drawer guide rail is oriented more obliquely than when only one guide rail has two running sections.

[0040] Advantageously, the entire longitudinal extent of the running surface exactly has two running sections.

[0041] The running surface of the body guide rail and / or the intermediate guide rail preferably exactly includes two running sections, wherein the plane of the first running section and the plane of the second running section each preferably have a longitudinal extent. The longitudinal extent of the plane of the first running section and the longitudinal extent of the plane of the second running section preferably together form the total longitudinal extent of the running surface. In addition, the first running section may have a plurality of planes, each plane having a longitudinal extent, and thus the sum of the longitudinal extents of the planes of the first running section forms the longitudinal extent of the first running section.

[0042] Equally advantageously, the longitudinal extents of the first and second running sections each have a starting point and an end point, wherein the starting point of the longitudinal extent of the second running section and the end point of the longitudinal extent of the first running section are each formed at the end-side edge of the running surface.

[0043] Preferably, the total longitudinal extent of the running surface extends from the starting point of the longitudinal extent of the second running section to the end point of the longitudinal extent of the first running section. In the installed state where the body guide is mounted on the furniture body, preferably, the starting point of the longitudinal extent of the second running section is located in the direction of the rear wall of the furniture body, while the end point of the first longitudinal extent is located at the opening of the furniture body or in the front region of the side wall of the furniture body. In the closed state of the movable furniture part, in the case of the body guide, the end point of the longitudinal extent of the second running section is preferably arranged near the front part of the movable furniture part. Since the intermediate guide is movable relative to the body guide, the end point and the starting point of the longitudinal extent of the intermediate guide are displaced. In this case, the starting point of the longitudinal extent of the second running section of the intermediate guide is arranged at the side end portion on the closing direction of the running surface, while the end point of the longitudinal extent of the first running section of the intermediate guide is arranged at the side end portion on the opening direction of the running surface.

[0044] In the case where the device is installed on the furniture and in the closed state of the movable furniture part, the starting point of the longitudinal extent of the second running section of the intermediate guide is also directed in the direction of the rear wall of the furniture body.

[0045] Advantageously, the end point of the longitudinal extent of the second running section corresponds to the starting point of the longitudinal extent of the first running section.

[0046] Advantageously, the end point of the longitudinal extent of the second running section and the starting point of the longitudinal extent of the first running section are located within the running surface. Preferably, 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 more than 60%, preferably more than 70%, more than 80%, more than 90% away from the starting point of the longitudinal extent of the second running section.

[0047] Equally advantageously, in the installed state of the device, the first running section is formed in the front-end region of the guide in the opening direction of the drawer guide.

[0048] In the state where the device is installed on the furniture, the front-end region of the body guide is preferably directed in the opening direction of the furniture body. In the closed state of the movable furniture part, the front-end region of the body guide is arranged near the front part of the movable furniture part.

[0049] Furthermore, in the closed state of the movable furniture part, the front-end region of the intermediate guide rail is preferably oriented in the opening direction of the furniture body. The front-end region of the intermediate guide rail is also oriented in the direction of the movable furniture part, wherein in the closed state of the movable furniture part, the front-end region of the intermediate guide rail is arranged near the front part of the movable furniture part, in particular near the drawer front of the drawer. During the opening movement of the movable furniture part in the opening direction, the relative movement between the drawer guide rail and the intermediate guide rail causes the front-end region of the intermediate guide rail to move further and further away from the front part of the movable furniture part.

[0050] Advantageously, the longitudinal extent of the second running section of the guide rail extends over 60% to 90% of the total longitudinal extent of the running surface of the guide rail.

[0051] The longitudinal extent of the second running section advantageously extends over 60%, 65%, 70%, 75%, 80%, 85% of the total longitudinal extent of the running surface of the body guide rail and / or the intermediate guide rail.

[0052] Preferably, the longitudinal extent of the second running section extends from the starting point to the end point of the second running section, wherein the starting point of the second running section starts at the rear-side edge of the running surface.

[0053] In the case of the body guide rail, the rear-side edge of the running surface where the starting point of the second running section is located is preferably arranged in the central region to the rear region of the side wall of the furniture body in the state where the device is installed on the furniture. The rear-side edge of the body guide rail is preferably oriented in the direction of the rear wall of the furniture body and is transverse to the moving direction of the intermediate guide rail and / or the drawer guide rail.

[0054] In the case of the intermediate guide rail, the rear-side edge of the running surface where the starting point of the second running section is located is arranged in the rear region of the side wall of the furniture body in the closed state of the movable furniture part, wherein the rear region of the side wall of the furniture body is connected to the rear wall of the furniture body. During the opening movement of the movable furniture part, the rear-side edge of the running surface of the intermediate guide rail moves along the body guide rail, and as a result, the rear-side edge of the running surface of the intermediate guide rail is preferably positioned within the central region of the running surface of the body guide rail in the fully open state of the movable furniture part.

[0055] Another advantageous possibility is obtained if the longitudinal extent of the first running section of the guide rail extends over 10% to 40% of the total longitudinal extent of the running surface of the guide rail.

[0056] The longitudinal extent of the first running section advantageously extends over 10%, 15%, 20%, 25%, 30%, 35% of the total longitudinal extent of the running surface of the body guide rail and / or the intermediate guide rail.

[0057] Preferably, the longitudinal extent of the first running section extends from the start of the first running section to the end point of the first running section, wherein the end point of the first running section is arranged at the front side edge of the running surface.

[0058] In the case of the body guide rail, the front side edge of the running surface where the end point of the first running section is located is preferably arranged on the front area of the side wall of the furniture body in the state where the device is installed on the furniture, wherein the front area of the side wall of the furniture body is oriented towards the opening of the furniture body.

[0059] In the case of the intermediate guide rail, the front side edge of the running surface having the end point of the first running section is arranged on the front side edge of the running surface of the body guide rail in the closed state of the movable furniture part. During the opening movement of the movable furniture part, the front side edge of the running surface of the intermediate guide rail moves along the body guide rail, and as a result, the front side edge of the running surface of the intermediate guide rail preferably pauses in the central area of the running surface of the drawer guide rail and is at a certain distance from the running surface of the body guide rail in the fully open state of the movable furniture part.

[0060] Equally preferably, in the installed state of the device, the longitudinal extent of the second running section is horizontally oriented.

[0061] In the installed state, the body guide rail is connected to the side wall of the furniture body, wherein the longitudinal extent of the running web or the running surface of the guide rail is horizontally oriented. In the case of a guide rail having two running sections on its running surface, it is advantageous that only the longitudinal extent of the second running section of the running surface is horizontally oriented. The longitudinal extent of the first running section of the guide rail having two running sections is preferably inclined with respect to the horizontal direction and the vertical direction in the installed state.

[0062] In the installed 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 advantageously vertically spaced apart from each other.

[0063] The vertical spacing or height difference 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. In the direction of the movable furniture part, the end point of the longitudinal extent of the first running section is advantageously closer than the end point of the longitudinal extent of the second running section.

[0064] Equally preferably, the vertical spacing or height difference between the start point and the end point of the longitudinal extent of the first running section is 0.2 to 2 mm.

[0065] By means of the inclined arrangement of the plane of the first running section with respect to the plane of the second running section, a height difference is preferably achieved, whereby the downward movement of the movable furniture part in the open state can be offset.

[0066] One advantageous embodiment of the present invention is a piece of furniture having a movable furniture part, which can be moved relative to the furniture body in the opening and closing directions by means of a device according to one of the foregoing embodiments.

[0077] In Figure 1The furniture 1 shown in the figure has a furniture body 2 and a drawer 3 that can move relative to the furniture body 2. The drawer 3 can be moved relative to the furniture body 2 in the opening direction P1 and the closing direction P2 by means of a device 4 according to the invention - for example, a drawer pull-out guide. The furniture body 2 has a base 5, an upper panel 6, a rear wall 7, and two side walls 8, 9. The device 4 is preferably fixed to the side walls 8, 9 of the furniture body 2. The device 4 designed as a full-extension slide preferably has a body guide rail 10, an intermediate guide rail 11, and a drawer guide rail 12 (see Figure 2), where the body guide rail 10 is mounted on the side walls 8, 9 of the furniture body 2. Advantageously, the body guide rail 10 is attached to each of the side walls 8, 9 of the furniture body 2, and the body guide rail 10 is preferably attached to the side walls 8, 9 of the furniture body 2 in a mirror-symmetrical manner. In addition, the drawer 3 is preferably detachably connected to the drawer guide rail 12. The drawer 3 preferably has a drawer bottom 13, drawer side walls 14, 15, a drawer front 16, and a drawer rear wall 17, where the drawer bottom 13 preferably rests on the drawer guide rail 12.

[0078] The device according to the invention is shown in Figure 2, where the body guide rail 10 has a running web 18. The running webs 19, 20 of the intermediate guide rail 11 are preferably arranged above and below the running web 18 of the body guide rail 10 (see Figure 3). In this case, rolling elements 21 are arranged between the lower running web 19 of the intermediate guide rail 11 and the running web 18 of the body guide rail 10. During the movement of the intermediate guide rail 11 relative to the body guide rail 10 or during the opening or closing movement of the drawer 3, the rolling elements 21 can move along the running surface 22 of the lower running web 19 of the intermediate guide rail 11 and the lower running surface 23 of the running web 18 of the body guide rail 10. Preferably, additional rolling elements 24 are arranged between the running web 18 of the body guide rail 10 and the upper running web 20 of the intermediate guide rail 11, and the rolling elements 24 can move along the upper running surface 25 of the running web 18 of the body guide rail 10 and the running surface 26 of the upper running web 20 of the intermediate guide rail 11.

[0079] Rolling elements 21, 24 are arranged, for example, in a carrier 27, wherein the carrier 27 preferably has an upper row including the rolling element 24 and a lower row including the rolling element 21. The running web 18 of the body guide rail 10 is preferably arranged between the two rows of rolling elements. In addition, on the side surface of the carrier 27, the carrier 27 also has rolling elements 28, wherein the rolling elements 28 move along the lateral running web 29 of the body guide rail 10 and / or the lateral running web 39 of the intermediate guide rail 11, so that the carrier 27 can move along the running webs 18, 19, 20 and the lateral running webs 29, 39 of the intermediate guide rail 11 and the body guide rail 10. An engaging element 30 is additionally formed on the carrier 27 and interacts with a synchronizing wheel 31 on the intermediate guide rail 11. The synchronizing wheel 31 is rotatably arranged on the intermediate guide rail 11, and the synchronizing wheel 31 also interacts with an engaging profile 32 on the second carrier 33. By the engagement of the synchronizing wheel 31 in the engaging element 30 of the carrier 27 and the engagement in the engaging profile 32 on the second carrier 33, the movement of the intermediate guide rail 11 and the drawer guide rail 12 in the opening and closing directions P1, P2 can be synchronized, for example.

[0080] The second carrier 33 has a row of rolling elements 34, wherein the rolling elements 34 are arranged between the upper running web 20 of the intermediate guide rail 11 and the running web 35 of the drawer guide rail 12. The rolling elements 34 can move along the upper running surface 36 of the upper running web 20 of the intermediate guide rail 12 and the running surface 37 of the running web 35 of the drawer guide rail 12. The drawer 3 is preferably rested on the upper surface of the running web 35 of the drawer guide rail 12 via the drawer bottom 13. The second carrier 33 preferably further includes a lateral supporting element 38, wherein the lateral supporting element 38 is arranged, for example, between the lateral running web 39 of the intermediate guide rail 11 and the lateral running web 40 of the drawer guide rail 12. The carrier 33 also moves along the running surfaces 36, 37 and the lateral running surfaces 39, 40 of the intermediate guide rail 11 and the drawer guide rail 12 in a supported manner, for example.

[0081] Figure 4 and 5 The body guide rail 10 is shown in different views. The body guide rail 10 is integrally formed as a bent metal plate member, for example. The body guide rail 10 includes a mounting strip 41, a bottom plate 42, a lateral running web 29 and a running web 18. By means of the mounting strip 41, the body guide rail 10 can be fixed to the side walls 8, 9 of the furniture body 2 by fastening means such as screws. The bottom plate 42, the lateral running web 29 and the running web 18 preferably form a U shape, wherein the bottom plate 42 connects the mounting strip 41 and the lateral running surface 29 to each other. The U shape preferably opens in the direction of the mounting strip 41. The lateral running surface 29 preferably connects the running surface 18 and the bottom plate 42.

[0082] As Figure 4 and 5As shown, the running surface 25 of the body guide rail 10 advantageously has two running sections 43, 44. The running sections 43, 44 each preferably form a plane, where the planes of the running sections 43, 44 have a longitudinal extent L1, L2 and a lateral extent. The longitudinal extent L1 of the first running section 43 extends from a starting point 45 to an end point 46, where the end point 46 preferably terminates at the front-side edge 47 of the running surface 25 of the body guide rail 10. The longitudinal extent L2 of the second running section 44 extends from a starting point 48 to an end point 49, where the starting point 48 begins at the rear-side edge 50 of the running surface 25 of the body guide rail 10. In the installed state of the body guide rail 10, the front-side edge 47 of the running surface 25 of the body guide rail 10 is arranged on the side walls 8, 9 of the furniture body 2, near the opening 52 of the furniture body 2. In the case where the drawer 3 is closed, the front-side edge 47 of the running surface 25 of the body guide rail 10 is located in the downstream area of the drawer front 16.

[0083] Since the first running section 43 smoothly merges into the second running section 44, the end point 49 of the longitudinal extent L2 of the second running section 44, for example, corresponds to the starting point 45 of the longitudinal extent L1 of the first running section 43.

[0084] The longitudinal extent L1 of the plane of the first running section 43 is preferably oriented obliquely with respect to the longitudinal extent L2 of the plane of the second running section 44. The lateral extents of the planes of the first and second running sections 43, 44 are perpendicular to the longitudinal extents of the planes of the first and second running sections 43, 44, where the lateral extent of the first running section 43 is parallel to the lateral extent of the second running section 44. The lateral extents of the two running sections 43, 44 are preferably not inclined with respect to each other. The angle α between the longitudinal extent of the first running section and the longitudinal extent of the second running section is preferably less than 180° and greater than 170°.

[0085] In the state where the body guide rail 10 is installed on the side walls 8, 9 of the furniture body 2, the longitudinal extent L2 of the plane of the second running section 44 is preferably oriented horizontally, where the longitudinal extent L1 of the plane of the first running section 43 is oriented transversely with respect to the horizontal direction or the vertical direction. 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 apart from each other or have a height difference (see Figure 5 ). This height difference advantageously helps to compensate for the lowering of the drawer 3 in the open state. The total longitudinal extent of the running surface 25 includes the longitudinal extent L1 of the first running section 43 and the longitudinal extent L2 of the second running section 44, where the longitudinal extent L1 of the first running section 43 is 10% to 40% of the total longitudinal extent of the running surface 25 of the body guide rail 10.

[0086] In Figures 6 to 8In [the figure], a device 4 in different states during the movement of the drawer 3 in the opening direction is shown. Figure 6 The closed state is shown, Figure 7 The semi-extended state is shown, Figure 8 The fully extended or fully open state is shown. In Figures 6 to 8 [the figure], only the body guide rail 10 has two running sections 43, 44.

[0087] In the closed state of the drawer 3, the three guide rails 10, 11, 12 are stacked on top of each other vertically (see Figure 6 ), where the rear ends of the running surfaces 22, 26, 36, 37 of the intermediate guide rail 11 and the drawer guide rail 12 preferably protrude beyond the second running section 44 of the running surface 25 of the body guide rail 10. For example, in the state where the body guide rail 10 is installed on the side walls 8, 9 of the furniture body 2, the rear ends of the running surfaces 22, 26, 36, 37 of the intermediate guide rail 11 and the drawer guide rail 12 are located near the rear wall 7 of the furniture body 2. In the installed state, the first running section 43 of the running surface 25 of the body guide rail 10 is preferably arranged near the opening 52 of the furniture body 2, where in the closed state of the drawer 3, the front ends of the running surfaces 22, 26, 36, 37 of the drawer guide rail 12 and the intermediate guide rail 11 are preferably also arranged near the opening 52 of the furniture body 2. Since the upper surface of the drawer guide rail 12 is connected to the drawer bottom 13 in the installed state, for example, during the opening and closing movement of the drawer 3, the front end of the running web 35 of the drawer guide rail 12 and thus the front end of the running surface 37 of the drawer guide rail 12 preferably rest on the drawer front 16, and the rear end of the running web 35 of the drawer guide rail 12 rests on the drawer rear wall 17.

[0088] In the closed state of the drawer 3, the brackets 27, 33 are arranged, for example, centrally on the guide rails 10, 11, 12 or on the running surfaces 22, 23, 25, 26, 36, 37 of the guide rails 10, 11, 12. Therefore, the bracket 27 - where the rolling elements 21, 24 are arranged between the running web 18 of the body guide rail 10 and the running webs 19, 20 of the intermediate guide rail 11 - is preferably located on the second running section 44 of the running surface 25 of the body guide rail 10. In this way, the longitudinal extent of the running webs 19, 20, 35 or the running surfaces 22, 26, 36, 37 of the intermediate guide rail 11 and the drawer guide rail 12 is preferably oriented parallel to the longitudinal extent L2 of the second running section 44 of the body guide rail 10. In other words, in the state where the body guide rail 10 is installed on the side walls 8, 9 of the furniture body 2, the longitudinal extent of the running surfaces 22, 26, 36, 37 of the intermediate guide rail 11 and the drawer guide rail 12 and the longitudinal extent L2 of the second running section 44 of the body guide rail 10 are preferably oriented horizontally.

[0089] For example, if the drawer 3 is now moved from the closed position in the opening direction P1, the intermediate guide rail 11 moves relative to the body guide rail 10, and the drawer guide rail 12 moves relative to the intermediate guide rail 11 and the body guide rail 10 (see Figure 7 ). During this process, the brackets 27, 33 move along the running surfaces 22, 23, 25, 26, 36, 37 of the guide rails 10, 11, 12. The bracket 27 - in which the rolling elements 21, 24 are arranged between the running webs 18 of the body guide rail 10 and the running webs 19, 20 of the intermediate guide rail 11 - hardly moves in the opening direction P1. This means that the bracket 27 preferably remains on the second running section 44 of the body guide rail 10 even in the semi-extended state (see Figure 7 ), so that the running surfaces 22, 26, 36, 37 of the drawer guide rail 12 and the intermediate guide rail 11 continue to be oriented horizontally. In the semi-extended state, the bracket 33 - in which the rolling elements 34 are arranged between the running web 20 of the intermediate guide rail 11 and the running web 35 of the drawer guide rail 12 - is located approximately halfway along the running web 20 of the intermediate guide rail 11 and approximately in the front half of the running web 18 of the body guide rail 10. In this case, the front half of the running web 18 of the body guide rail 10 is preferably the half of the running web 18 facing the opening 52 of the furniture body 2.

[0090] During a further opening movement of the drawer 3 or the intermediate guide rail 11 and the drawer guide rail 12 in the opening direction P1, the bracket 27 reaches the rear end of the intermediate guide rail 11 during the relative movement between the intermediate guide rail 11 and the body guide rail 10, where there is a boundary feature structure (not shown) for the bracket 27 at the rear end of the lateral running web 39 of the intermediate guide rail 11, so that the bracket 27 can move along the opening direction P1 together with the intermediate guide rail 11 at the rear end of the intermediate guide rail 11 through this boundary feature structure. In this case, the bracket 27 preferably reaches the stop 51 located at the front end of the body guide rail 10 (see Figure 4 ), so that the bracket 27 can no longer move further in the opening direction P1.

[0091] During the relative movement between the intermediate guide rail 11 and the drawer guide rail 12, the bracket 33 preferably also moves to the rear end of the drawer guide rail 12. In this case, for example, at the rear end of the lateral running web 40 of the drawer guide rail 12, there is a boundary feature structure (not shown) for the bracket 33, so that the bracket 33 can move along the opening direction P1 together with the drawer guide rail 12 at the rear end of the drawer guide rail 12 through this boundary feature structure.

[0092] When the drawer 3 is fully opened (see Figure 8), the carrier 27 or the rolling element 24 is preferably located between the stop 51 of the body guide 10 and the boundary feature of the intermediate guide 11, so that the rolling element 24 is now located on the first running section 43 of the body guide 10. As a result, the longitudinal extent of the running surface of the carrier 27 and thus of the intermediate guide 11 is preferably directed obliquely upwards or obliquely with respect to the horizontal or vertical direction. That is to say, the longitudinal extent of the running surfaces 22, 26, 36 of the intermediate guide 11 is directed obliquely with respect to the longitudinal extent L2 of the second running section 44 of the body guide 10. Due to the inclined position of the running surfaces 22, 26, 36 of the intermediate guide 11, the running surface 37 of the drawer guide 12 is also directed obliquely upwards, wherein the longitudinal extent of the running surfaces 22, 26, 36 of the intermediate guide 11 and the longitudinal extent of the running surface 37 of the drawer guide 12 are substantially parallel.
