The guide rail is accordingly a fixed rail or carcass rail, which is fixed in the use state fixed in position on the mating section as a body by means of the fastening element.
    In particular, the invention relates to a furniture element guide rail or a guide rail of a furniture element guide system or a guide rail of a furniture part drawer or a furniture full extension.
    In the manufacture of the guide rail, the rail body and the
    Fastener each provided from a separate pre-produced element, which are firmly connected to each other for the completion of the guide rail.
    Preferably, the fastener is made of an originally flat flat or
    Strip material such as e.g. a sheet metal or steel sheet by a forming process such. B. made a bending process. The rail body can be made according to a sheet or z. B. be a rolled, drawn or pressed metal profile.
    Preferably, the fastener, which is also referred to as adapter angle or mounting angle, brought from a shape in the form of at least approximately rectangular flat sheet material, inter alia by a stamping process and a cold forming process in its final angular basic shape. In the basic form, the fastening element is preferably L-shaped or has two legs which are at an angle, in particular at right angles to one another.
    The rail body is the part of the guide rail, which cooperates with another guide rail such as a center rail or a push element rail or acting between the rails bearing means of the relevant guide system.
    The essence of the invention is that, in the connected state of the fastening element with the rail body, the edge portion of the fastening element is connected butt-abutting with the rail side upright on the rail body in the use state of the guide rail. The fastening element is attached to the rail body preferably cohesively connected. The fastening element preferably comprises two legs, which are connected together along a bending line and aligned with each other at an angle. The fastening element is preferably formed in one piece from a sheet metal material.
    The guide rail or the rail body preferably has an upright or vertically oriented in the use state surface side, which in the use state of the
    Counter section as an inside of a body side wall facing. The
    Surface side is in particular a longitudinal side or preferably over the entire or substantial length of the rail body strip-shaped extending side such. Legs
    Side wall of the guide rail or the rail body. The upright
    Surface side on the rail body or the rail body side wall is preferably an outer side of a rail body, for example, in cross-section L-shaped or U-shaped or a wall of a cross-sectionally four- or polygonal rail body.
    It is advantageous that the fastening element is configured symmetrically. Preferably, the fastening element is in particular mirror-symmetrical. The fastening element is advantageously symmetrical to a plane of symmetry which is perpendicular to the two legs of the fastener and passes through the central axis of the fastener, said central axis is in the connected state with the rail body in the direction of the longitudinal axis of the rail body, ie the center of the fastener defined in the longitudinal direction of the rail body or the guide rail. This direction coincides with the direction of the bending line over which the two legs of the
    Fixing element at an angle to each other.
    It is advantageous that the fastener identically both as a front or rear fastener on a guide rail as well as a right guide system assembly or a right partial or full extension unit or for a left guide system assembly or a left partial or full extension Construction unit is usable. This is economically advantageous, in particular with regard to the production, provision, storage and processing of the fastener. Only one embodiment of the fastener is needed, which is universally applicable.
    It is advantageous that the connection of the fastening element with the rail body is set up exclusively by the blunt connection of the edge section of the fastening element with the surface side on the rail body. This is manufacturing technology advantageous.
    It is also advantageous that the fastening element is formed in the basic form as an angle element with two mutually angled legs, wherein a leg of the flat material portion with the opposite main sides and the narrow
    Having edge portion. The production of the fastener of a sheet material is thereby easily possible.
    So far, a comparatively large surface portion on the rail body on the one hand and a comparatively large surface area on the fastener are required for the connection of the fastener and the rail body. For the known connection of the fastener with the rail body, the relevant z. B. sheet metal sections, in particular, overlapping each other in a planar manner brought together in a surface installation and connected to each other. In this case, the surface portions in mutual contact and the two opposite sheet metal sections, for example by connecting elements such
    Rivets or connected by a clinching process.
    The invention proposes a completely different approach, according to which only comparatively much smaller surfaces of the sheet metal sections on the rail body and on
    Fastener be brought into abutting contact with each other and welded together or, for example glued together or soldered together, preferably are laser-welded together. The weld formed in this case can be on both sides along the upper boundary of the edge portion and / or along the lower
    Be formed boundary of the edge portion. The weld seam at the top and bottom can preferably be continuous for maximum connection stability or can be formed with an interruption over the length of the boundary profile of the edge section.
    The interconnected according to the invention surface sections are only one
    Fraction of the area that in known connections of guide rail and
    Fastener come into contact with each other or are connected to each other.
    For example, in the guide rail according to the invention, the size of the for
    Connection required area on a single fastener in the range of about 15 mm2, and thus the required area for connection to the rail body corresponding to about 15 mm2. In this case, two identical fastening elements are provided on the guide rail.
    In contrast, in known comparable guide rails with two fastening elements on the guide rail, a surface required for the connection is located at one
    Fastening element or the rail body in the order of about 120 mm2.
    This area is z. B. through the top of a horizontal leg of
    Attachment provided.
    This means that the guide rail according to the invention comes with a connecting surface, which amounts to only about 12% of the connecting surface of known guide rails. Among other things, the area saved means that the fastening element or a horizontal limb of the fastening element can be made smaller around this area. This is advantageous with the invention, a material savings and a corresponding reduction in weight possible, based on the fastener. Accordingly, the extension of the horizontal leg of the fastener of the z. B. right-angled bend to the free end, on which the edge portion is present with its front side, comparatively much shorter than is the case with known fasteners or adapter angles.
    In cross-section, the fastening element preferably has an at least approximately L-shape with a leg oriented horizontally in the use state and a leg oriented vertically. At least one leg has to the plane formed by the leg a raised portion to the plane, which is formed from the strip material by deformation. With the raised portion is advantageously a mechanical stiffening of the
    Fastener achieved with respect to a flat or planar shape. The raised portion is preferably formed substantially in the rail body side or horizontally oriented leg. The raised portion preferably extends into the angular region and beyond it to slightly into the region of the other or vertical leg.
    With a corresponding degree of the rail body-side leg, which concerns its extension from the bend to the free end, in particular a distance of the rail body is given to the counter portion, so for example from an inner side of a side wall of a furniture body. Depending on the length of the rail body-side leg, the possibility of connecting the fastening element with the rail body is predetermined. With the size or area of the other or body-side leg of the fastener, the portion or the surface of the fastener is determined, which for attachment to the mating portion such. B. the MöbelkorpusSeitenwand serves.
    Preferably, the thickness of the edge portion of the rail body-side leg, so the height of the front-side strip-shaped surface over which the blunt connection is realized with the upright surface side of the rail body, the
    Material thickness of the flat material of the fastener. The flat material or the formed sheet metal material preferably has a thickness of between 0.4 and 1.5 millimeters. Preferably, the material thickness of the fastener over its in
    Substantial total training 0.8 millimeters. The edge section points to the blunt
    Connection an end face or end face, which is flat or is aligned at right angles to the two opposite main or surface sides of the mounting bracket. The surface of the edge portion, the z. B. a punching or a laser
    Cutting processing of the strip material has arisen, is accordingly flat or lies in a plane. Thus, the edge portion or its flat end face is advantageously suitable, over the surface of the front side blunt or flat fitting with the also flat
    Surface side of the rail body to be connected. The abutting surfaces of the end face of the edge portion of the fastener on the one hand and the surface side of the rail body on the other hand are therefore over the entire surface in the contact, which is advantageous, in particular for a cohesive connection.
    The vertically oriented leg of the fastener has advantageous
    Connecting means or connecting sections on, for. B. through holes as
    Screw holes for screwing the fastener with attached thereto guide rail on a counter portion, such as a side wall of a furniture body.
    Another advantage is to be seen in that the edge portion of the fastener, which is butt-joined to the upright-facing surface side connected to the rail body, is designed strip-shaped. About the strip-shaped design of the interconnected sections depending on the course of the edge portion, the compound is advantageously set up. In particular, the connection with the edge section can be established on the surface side over a comparatively small area. This also results in a variety of different ways to attach the edge portion according to its linienartigem course on the surface side. In other words, that can
    Mounting element optionally be mounted in particular at different heights or in different vertical positions on the rail body or its surface side.
    It is also advantageous that the shape of the edge portion of the shape of the at
    Edge portion adjacent flat material portion of the fastener is predetermined. In particular, can be influenced by an impression in the relevant horizontal leg of the fastener, the shape of the edge portion. The shape of the edge section refers to the line over the length of the edge course or with
    View from the front or perpendicular to the plane of the narrow end of the edge. In a simple L-shaped fastener made of a flat sheet that is bent at right angles, the shape of the edge portion is a straight line. If z. B. an impression as a depression or increase in the horizontal leg of the fastener is present, the shape of the edge portion due to the imprint according to a curve z. B. down or pulled up, deviating from the straight line according to the flat leg without imprinting.
    An advantageous modification of the invention is given by the fact that the
    Edge portion adjacent flat material portion one to adjacent areas of the
    Flat material section recessed and / or elevated area comprises. This is advantageous from a mechanical point of view, in particular with regard to static and dynamic loads acting on the guide rail and over the
    Fastening element are introduced into the opposite section. The recessed and / or elevated region, such as a bead or dimple, is preferably offset upwardly relative to the useful state on the leg of the fastening element connected to the rail body. The upwardly deformed or offset region preferably has an oblique material portion, which is sloping from the other leg to the edge portion or is formed in the manner of a ramp, whose top is but just inclined.
    The achieved with the recessed and / or elevated area stabilization or stiffening of the fastener is advantageous in the use state, for example, if a drawer with a comparatively large storage volume is heavily loaded on the associated guide system, which in addition to the weight of the empty drawer an additional
    Mass of, for example, over 50 kilograms can be added. The occurring significant bending loads and / or torsional loads on the guide system is received via the one fastening element or preferably two fastening elements and transmitted to the counter portion or a cabinet side wall.
    Preferably, two or more fasteners are provided on a guide rail so on a structural unit of a partial or full extension. Drawers are usually about two units of a partial or full extension, so on each longitudinal side of the drawer a unit, slidably received on the body.
    It is also of advantage that the flat material section adjoining the edge section has in each case a lateral region, wherein the two lateral regions lie on a common plane, and an increased flat material region is provided between the two lateral regions. This is based on an end view or a frontal view perpendicular to the end face of the edge portion.

Opposite a z. B. straight line shape of the edge portion, so if the leg is a flat horizontal surface in use, can be a particularly stable or higher mechanically resilient guide rail or a higher loadable connection between the fastener and the surface side of the rail body realize the same material use.
    Another advantageous embodiment of the invention results from the fact that the edge profile has staggered straight sections, which are connected to one another via an existing between the straight sections paragraph. The straight sections include, for example, two lower lying and an upwardly offset straight section. The transition between two straight sections may be angular or curved. Such a shape increases the stability of the guide rail or the guide system.
    Moreover, it is advantageous if the rail body is formed as enclosed by wall sections of the rail body hollow profile. The hollow profile is preferably slotted open in the use state or open. Preferably, the hollow profile has an underside or a flat lower horizontal wall section, on which in each case along the two longitudinal edges of a right-angled upwardly projecting in the use state preferably perpendicular wall section connects. On one of the vertical wall sections, the at least one fastening element is fixedly connected to the outside. At each of the two vertical wall sections closes at the respective upper edge over the at least substantial length of the rail body an inwardly with, for example, 45 degrees angled upper web sections. The free ends of the two web sections converge towards each other, but remain separated over a width distance, so that the rail body is open above a longitudinal slot over its length. In the volume enclosed by the rail body, portions of a middle rail are received in a full extension, wherein the middle rail extends upward through the longitudinal slot. In addition, a carriage with bearing bodies of bearing means between walls of the hollow profile rail body and walls of the center rail is housed.
    Relative to the height of the vertical wall portion, which forms the upright surface side of the rail body, two partial areas of the edge portion or its narrow end faces are preferably mounted in the lower region and a portion slightly higher up on the upright surface side. The lower limit of the lower two
    Subareas of the edge portion is preferably slightly offset upwards to the lower edge of the vertical wall portion and thus to the underside of the horizontal wall portion of the rail body. This is advantageous, the bottom of the horizontal leg of the
    Fastening something to the bottom of the rail body or the
    Horizontal wall section offset upwards exists.
    The bottom of the horizontal leg of the fastener and the bottom of the
    Horizontal wall section can also be flush.
