Description

Track for sliding door guard

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a track for a sliding door guard, in particular to a furniture or household appliance or partition, the track having at least two guide rails for the pulleys that are offset from one another in the vertical direction.

DE 255 31 75 discloses a sliding door guard in which a track is fixed on an upper base, in which a plurality of guide rails are arranged one above the other. Thus, a particularly compact construction is formed in which the profile is formed in a single piece as an extrusion profile. This extruded profile is highly stable, and of course the material consumption will also increase due to the deep wall thickness. This would make the extruded track profile more expensive.

It is an object of the invention to provide a track for a sliding door guard which can be produced easily and cost-effectively.

In order to achieve the above object, the present invention provides a rail for a sliding door guard having at least two guide rails for pulleys which are mutually offset in a vertical direction, the rail being single-piece Made of bent sheet metal.

According to the invention, the track is made in one piece from a curved sheet metal, so that the material is used less when compared to the extruded extrusion profile. Thus, the track can be made practically and cost-effectively, in which case it is also possible to manufacture a smaller number of pieces.

According to a preferred embodiment of the invention, the curved metal sheet has a thickness of between 0.4 mm and 3 mm, in particular between 0.5 mm and 1.5 mm. Thus, the track can be made according to the weight load, where the smaller and lighter track for the sliding wing can be formed to be thinner than the track for the heavier sliding door.

Preferably, the first and/or second rails are formed in a curved or V-shape in a cross-sectional view. Thus, the guide rails provide good lateral stability when guided, in which case the pulleys are run on the track in an automated centering manner by weight loading.

According to a preferred configuration, when the metal sheet does not completely prevent the metal sheet from bounce off after the bending process, the track has a turning section that is at least in regional contact or a nearly touching turning section. Such (almost) contact segments increase the stability of the track. Alternatively, the (almost) contacted segments can be additionally connected by means of a fixing medium, for example by welding or bonding in a material-bonding manner. Or other fixed media to connect, for example, by rivets, bolts or deformation techniques, for example, by continuous caulking or casting. By means of (almost) contact, they are optionally additionally fixed to each other, in particular to form a stable track. Thus, the guide rails are configured to be offset from each other in the vertical direction to achieve an advantageous lever ratio so that a large force can be absorbed when the thickness of the steel sheet is small. The manufacture of such a track can also be achieved industrially and efficiently at a higher quality when the adjacent sections are additionally fixed.

In a preferred construction of the invention, the track has a horizontal side waist that can be attached to the bottom or upper bottom of a cabinet piece of furniture. Here, the track can be latched on the upper side or the positive side of the upper bottom. The track may then have an upper vertical side waist that is coupled to the upper horizontal side waist with a horizontally projecting section on the lower side to form the first rail. In order to achieve a particularly tight construction, the track is provided with a lower second vertical side waist, at least a portion of which is disposed below the upper vertical side waist and has a horizontally protruding section on the lower side. A second guide rail is formed. In this configuration, the upper vertical side waist and the lower vertical side waist may be disposed in a plane such that at least a portion of the two side waists are located on an upper bottom or a positive side of the bottom, thereby improving stability. Sex. Alternatively, the upper vertical waist and the lower vertical waist may be offset from each other in different planes so that the rail is formed in a stepwise manner so that the construction space above the lower vertical waist can be used.

In the track of the present invention, it is preferred to provide an vacant area which is gripped by a stabilizer or an automatic accessor. Thus, the automatic accessor or the stabilizer can be disposed in a shielded manner behind the track, which can improve the appearance.

The sliding door guard may have a track made in accordance with the present invention in which a plurality of such tracks may be secured to one another over the impact connector. Here, the track may have one or more hollow chambers in which suitable connecting elements are inserted.

The invention will be described in detail below with reference to the accompanying drawings in accordance with the embodiments.

The cabinet furniture 1 comprises a concrete 2 having an upper bottom 3 to which a track 4 is fixed. Another rail may be additionally attached to the cabinet furniture 1 on a bottom such that both the front sliding door 5 and the rear sliding door 6 are guided on the upper and lower rails 4 on the upper bottom. In the following, only the track 4 on the upper bottom 3 will be described in detail, and the same track can also be fixed here on the bottom of the cabinet furniture 1. Alternatively, only one sliding guide function can be provided on the bottom.

The suspension of the front sliding door 5 is shown in Fig. 2, which grips the rear sliding door 6 via a U-shaped support 7 in at least one open position. At least one pulley is guided on the support 7, which can be run in a guide track above the track 4. Also shown in FIG. 2 is an automatic accessor or a housing 11 of a stabilizer, preferably a stationary automatic accessor having a lever 10 that engages an activator 9 The activator 9 is connected to the support 7. The sliding doors 5 and 6 can be stopped or held in the opening and closing directions by a stable automatic access device. The lever 10 thus travels through the vacant area in the wall of the track 4.

The suspension of the rear sliding door 6 is shown in FIG. The support member 8 is fixed to the rear sliding door 6 on the rear side, and the support member 8 is engaged with an automatic accessor or a shifting lever 10 of a stabilizer via the activator 9. The lever 10 is thus operatively held on the automatic accessor or housing 11 of the stabilizer, at which time the lever 10 also grips the vacant area in the track 4. The rear sliding door 6 is thus operatively held on the lower rail 21 of one of the rails 4 via at least one pulley.

A side view of the track 4 is shown in Figure 4, and it can be recognized that the front sliding door 5 is operatively held on the upper rail 20 via a pulley 12, and the rear sliding door 6 is operatively held below via a pulley 12. On the guide rail 21. Each of the pulleys 12 has a V-shaped bearing surface and the cross-sections of the guide rails 20 and 21 are also formed in a V shape. However, other geometric forms are of course possible, for example, a curved bearing surface in the form of a concave or convex shape and an inverted V-shaped bearing surface.

A cross-sectional view of the track 4 is shown in FIG. The rail 4 consists of a curved steel sheet having a thickness of between 0.4 mm and 3 mm, in particular between 0.5 mm and 1.5 mm. Here, the track 4 comprises an upper side waist 22 which can be supported on the upper bottom 3 or on the bottom. A horizontal side waist 22 is connected to the first vertical side waist 23, and a horizontal section projecting on the lower side thereof forms the upper rail 20. Here, two V-shaped aligned bars 24 and 25 are provided, wherein an outer vertical edge 26 is formed on the outer bar 25 which prevents the pulley 12 from jumping forward. Before the two V-shaped bars 28 and 29 are provided, a turning section 27 is connected downwardly on the edge 26, and the bars 28 and 29 extend parallel to the bars 24 and 25 on the lower side. In the region of the upper rail 20, the steel sheet of the rail 4 is doubled, giving the upper rail 20 a high degree of stability. The (almost) contact sections of the track 4 can still be additionally secured to one another, for example by welding, bonding, profiling or other means to enhance the stability of the track 4.

Attached to the bar 29 is a second vertical side waist 30 having a horizontally projecting section on the underside to form the lower rail 21. The vertical side waists 23 and 30 are thus arranged in a plane and at least a portion can abut on the positive side of the upper bottom 3 . The lower rail 21 is also formed by two V-shaped bars 31 and 32, wherein an outwardly projecting edge 33 is formed on the outer bar 32 to guide the pulley 12 for preventing the pulley 12 from jumping out.

Embodiments of the track change of the present invention are shown in Figures 6 through 12 below, where the same sections of track 4 of Figure 5 are denoted by the same reference numerals and only such changes are described.

A track 4' is shown in Figure 6, wherein the upper horizontal side waist 22' has a slightly raised intermediate section and two lower edge sections. Thus, the horizontal side waist 22' is positioned only on the upper bottom 3 with the edge sections.

In addition, the area under the bar 25 in the track 4' of FIG. 6 has been changed because the track 4' is not formed in a double wall manner in this area, but is configured with the bar 28' and the bar 25 Separated. Conversely, the bar 24 is supported by the bar 29 below the track 4' so that at least in this region there is a degree of stability by the construction of the double wall. The guide rail 20 as a whole achieves mechanical stability by a vertical turning section 27' formed on the horizontal bar 28', at which time the vertical turning section 27' is supported on the bar 25. The rest corresponds to the embodiment of Figure 5.

Figure 7 shows an altered track 4" with a longer horizontal side waist 22" abutting the upper bottom 3. The side waist 22" is thus formed linearly and, after bending, is converted into a vertical side waist 23. In this embodiment, the bar 25 on the guide rail 20 is also formed only in a single wall manner, and is not otherwise provided by the track 4" A section is supported because the bar 28" is configured to be spaced from the bar 25. A vertical section 27" is provided between the bar 28" and the vertical edge 26, which makes the bending of the rail 20 difficult In contrast, the bar 24 is supported by the bar 29 below.

In addition, the area of the lower rail 21 is slightly modified in FIG. 7 because the edge 33 does not end in a vertical section but is turned via a flange 34 to provide a vertical section 35 and an obliquely upward zone. Paragraph 36. Thus, one of the edges of the segment 36 is disposed in a shaded manner. At particularly high gravitational forces, the guide rails 21 can be supported by a section 36 that is slightly inclined upward. The rod 32 can also be joined to the segment 36 by means of a material combination, for example by bonding or welding.

In the track shown in Fig. 8, the area under the upper rail 20 has changed. Attached to the edge 26 is a vertical side waist 50 which is converted into a horizontal bar 51 before a vertical side waist 30 is formed on the track and a lower rail 21 disposed on the lower side of the vertical side waist 30. The upper rail 20 is thus completely formed in a single wall and is positioned apart from the horizontal bar 51.

The track 4 in Fig. 9 has been substantially changed in the region of the lower rail 21 because, in addition to the vertical edge 33, a flange 34 and a downward vertical section 35 are provided.

The track 4 in Figure 10 has also been changed in the region of the lower rail 21, since there are still two V-shaped bars 37 and 38 connected to support the bars 31 and 32 with respect to Figure 9 . Both the upper rail 20 and the lower rail 21 are formed in a double wall manner, making the rails 20 and 21 particularly stable.

A slight change with respect to Fig. 10 is shown in Fig. 11, wherein the lower rail 21 is formed in a double wall manner by the bar 37 only on one side.

Another embodiment of a track is shown in Fig. 12, in which the upper vertical side waist 23' is disposed laterally offset from the lower vertical side waist 30'. An upper rail 20' is formed on the upper vertical side waist 23', which is no longer V-shaped but is curved upward. Here, the upper rail 20' is supported on the two vertical bars 60 and 61. Attached to the bar 61 is a horizontal bar 62 which abuts against the vertical bar 60 at a curved section where the bar 60 and the bar 62 are secured to each other in the contact area for improved stability. A lower vertical waist 30' is disposed in the plane of the vertical bar 60, and a lower rail 21' is attached to the lower side thereof, which is formed by a substantially square contour like the upper rail 20'. The upper side is curved.

There is a configuration in which the respective side waists 23' and 30' are vertically disposed in a plane, and such a configuration is also possible.

The rail shown in Fig. 12 is shown in Fig. 13 as being provided with a sliding door guard, wherein a pulley 12' is provided on the support member 7, and a lower pulley 12' is provided on the support member 8. Each pulley 12' is guided on the upper rail 20' and on the lower rail 21', wherein the pulley 12' forms an arcuate or V-shaped bearing surface in a cross-sectional view and is automatically centered on the rail 20' and Guided on 21'. Each pulley 12' here has a side edge 70 which is larger in diameter than the guide rail 71.

The connection of the two tracks 4" on the impact side (i.e., the positive side) is shown in Figures 14 and 15. Each track 4" is similar to the track of Figure 7 in a cross-sectional view, wherein in order to connect the two tracks 4" A plurality of connecting elements 40 are inserted into the hollow chamber 41, which is made by the curved contour of the rail 4". The cross-section of each connecting element 40 is in the form of a triangle, and each connecting element 40 can be embedded in a hollow chamber below the outer bar 25 of the upper rail 20 and embedded in a hollow chamber below the bar 32 below the lower rail 21. . In contrast to Figure 7, the end section 36 can more easily extend over the lower rail 21 to form a closed hollow zone.

A cross-sectional contour is shown in Fig. 16 corresponding to the embodiment of Fig. 5, in which a track 4 is fixed to the upper bottom 3. In order to achieve a more stable fastening, an angular stiffening element 80 is fastened to the underside of the upper bottom 3, in particular by bolts, and the stiffening element 80 can likewise be fastened to the rail 4 on a vertical bearing surface, for example , fixed by bonding, bolts or other fixed media.

Figure 17 shows a track provided with two rails 20 and 21 arranged one above the other, each of the rails 20 and 21 being formed by a curved edge section of the metal sheet, and the intermediate section being guided upwardly in an angular manner. Above the bottom. Thus, the section immediately adjacent to the upper bottom is constructed in a double wall manner.

In Fig. 18, a cross section of a track is shown in which two rails 20 and 21 are disposed one above the other, and a vertical section 23 above the rail 20 and a vertical section 30 of the rail 21 are disposed on opposite sides of the rails 20 and 21.
