Definitions

  • the present invention relates to a guide device, in particular for sliding doors, with a running part with at least one roller and a guide rail made of a formed sheet steel, which has at least one track on which the at least one roller of the running part rolls, the guide rail in the area of the at least a track is formed in two layers, and the at least one track is convexly curved in cross section upwards.
  • the EP 1 498 382 B1 discloses a door header for an elevator, which is designed as a guide rail and on which rollers are guided on running surfaces.
  • the door transom is made from a bent sheet steel, this being designed as a single layer in the area of the running surfaces, so that only limited forces can be absorbed or the thickness of the sheet steel has to be selected to be correspondingly large.
  • the DE 10 2014 109 427 discloses a rail for a sliding door fitting made from a bent sheet steel. In the area of the raceways, two layers of sheet steel are at least partially in contact with one another, so that increased forces can be absorbed.
  • the rollers that roll on the rail are adapted to the contour of the track, with mostly no linear contact surface, but only one contact point having to carry the weight loads on the roller. This leads to a high pressure load, which can lead to deformation.
  • the guidance of the roller is not exact in the axial direction.
  • the DE 91 05 385 apparently a guide for a sliding door in which a roller rolls on two running flanks of a guide rail.
  • the DE 44 33 635 A1 discloses a guide device for a sliding door with all the features of the preamble of the independent claim.
  • the at least one raceway on the guide rail is convexly curved upwards in cross section, the roller contacting the curved raceway at two spaced-apart points which are arranged on opposite sides of a central plane of the raceway.
  • the central plane of the track can be a plane with a horizontal alignment of the guide rail on a convex upwardly curved track, which passes through the highest point, so that a section of the track is arranged on both sides of the central plane.
  • the center plane can be a mirror plane in relation to the raceway if the raceway is designed to be mirror-symmetrical on both sides of the center plane. The contact pressure at the individual points is reduced by the two spaced-apart contact points.
  • the two contact points enable the roller to be centered and thus improve the guidance of the roller in the axial direction.
  • comparatively high loads can be transferred to the running surface via the roller, since the running track is designed with two layers and the convex curvature gives it a high degree of rigidity.
  • the invention is a concave roller which rolls on a convex track.
  • the roller has a surface which is curved concavely in a radial section at least in regions.
  • the radius of curvature of the surface of the roller can be selected differently than the radius of curvature of the curved track.
  • the ratio of the radius of curvature of the surface of the roller to the radius of curvature of the curved running surface should be greater than 1, in particular between 1.1 and 1.5, for example between 1.1 and 1.3.
  • the surface of the roller can cling particularly well to the curvature of the track, which leads to good guiding properties.
  • good centering of the roller on the track is achieved.
  • the distance between the two points is at least 2 mm, in particular between 3 mm and 7 mm. A high level of lateral stability of the roller can thereby be obtained.
  • profiling can also be provided in the area of the track, which extends through both layers of the track. As a result, a relative movement of the two layers perpendicular to the longitudinal direction is made difficult or prevented.
  • the profiling can for example be designed as a bead or groove-shaped embossing which extends in the longitudinal direction of the guide rail. This bead or groove-shaped embossing also creates an area in which abrasion of the roller material, preferably plastic, can accumulate. This ensures that the roller runs smoothly on the respective track.
  • Such a profiling can for example be arranged in the area of a middle plane of the track or the roller in the longitudinal direction.
  • the ratio of the width of the roller to the width of the track is preferably greater than 1, in particular between 1.1 and 1.8. Only that area of the roller is taken into account, which is arranged adjacent to the track on the guide rail. Two radially protruding rings can also be formed on the roller, which laterally enclose the track on the guide rail.
  • the track is particularly strong if it is curved upwards in a central area.
  • the at least one roller can be produced from a roller bearing overmolded with plastic. Beading of a rolling bearing or pressing in or connecting several plastic parts by means of ultrasound for fixing to the rolling bearing can also be used. In particular, hard plastics such as POM can be used for the plastic material.
  • the guide device can be used with sliding doors that are guided overhead, the surface of the upper track being arranged at the same or a higher level than the underside of a top floor in order to achieve better load transfer.
  • the surface of the lower runway is arranged at the same or a higher level than the underside of a floor, with a sliding door running below being understood as a sliding door in which the engagement of the rollers in the runways is arranged in a lower furniture body area is.
  • a piece of furniture 1 in particular a piece of cabinet furniture, comprises a furniture body 2, on which a guide rail 3 of a guide device according to the invention is fixed on a top shelf 9.
  • the guide device can be used, for example, to move sliding doors, but other uses, such as movable room dividers or folding sliding doors, are also possible.
  • the guide rail 3 is made of a formed sheet steel, which has a thickness of less than 1 mm, for example, and an upper track 4 and a track 5 arranged below, which are arranged in a common vertical plane.
  • the guide rail 3 is supported with an upper horizontal leg 6 on an upper side of the upper floor 9 and has an upper vertical web 7 which extends to the upper track 4.
  • the upper raceway 4 is formed in two layers, and a lower vertical web 8 is formed integrally below the upper raceway 4 and extends to the lower raceway 5.
  • the surface of the upper track 4 is arranged at the same or a higher level than the underside of the upper floor 9 in order to achieve better load transfer through short lever ratios.
  • the vertical web 7 can be supported on an end edge of the top panel 9. As a result, the bending load is reduced when the track 4 is loaded with a weight load, since the load is transferred to the top panel 9 both via the horizontal leg 6 and the vertical web 7.
  • rollers 10 which can be moved on the tracks 4 or 5.
  • the rollers 10 are part of a running part, for example to guide a sliding door in a suspended manner.
  • Each roller 10 has a surface 11 which is curved in a radial section. Adjacent to the surface 11 are two radially protruding rings 12 and 13 which enclose the raceway 4 or 5.
  • the roller 10 In the area of a middle plane, the roller 10 has a groove-shaped recess 14 which prevents the roller 10 from making contact with the track 4 or 5 in this area.
  • the contact of the roller 10 takes place through two points 15 and 16, which contact the raceways 4 and 5 at a distance from a central plane, the distance in the axial direction of the roller 10 being between 2 mm and 8 mm, for example.
  • roller 10 is shown spaced from the upper track 4.
  • the surface 11 of the roller 10 is concave, that is to say curved inward, with a radius R 1 being provided which is, for example, in a range between 5 mm and 9 mm.
  • This radius R 1 is formed on both sides of the central recess 14, the curvature in the central area having a jump and converging in a V-shape.
  • the raceway 4 has an upper convex, i.e. outwardly curved, surface whose curvature with the radius R 2 is configured differently than the radius R 1 on the surface 11 of the roller 10.
  • the radius R 2 can, for example, be made smaller than the radius R 1 , for example in a range between 4 mm and 7 mm.
  • the ratio of the radius of curvature of the surface 11 of the roller and the radius of curvature of the curved track 4 can be in a range between 1.1 and 1.5.
  • the profile of the guide rail 3 is shown in detail.
  • two layers 40 and 41 are arranged one above the other, which contact one another at least in some areas, so that the lower layer 41 supports the upper layer 40 when a load is applied.
  • an upper layer 50 which is supported by a lower layer 51, is provided on the lower track 5.
  • a profile 42 or 52 is provided in a central area of each track, which is formed as an embossing and extends through both layers 40 and 41 or 50 and 51.
  • an upper surface 44 of an upper layer 40 of the raceway 4 has the radius of curvature R 2 , which extends continuously up to the area with the profile 42.
  • the profile 42 is designed as a groove-shaped recess, and a corresponding profile 43 is also shown in FIG the lower layer 41 is formed.
  • the profiling 42 enables the accumulation of abrasion of the roller 10, which could otherwise accumulate on the curved surface 44 of the raceway.
  • the profile 42 has a height H between 0.5 mm and 1.5 mm, so that impurities can accumulate over a long service life in order to maintain good rolling behavior of the rollers on the raceways for as long as possible.
  • the formed steel sheet ends at an edge 53 in a central area of the track 5.
  • FIG 3C a transition between the horizontal leg 6 and the upper vertical web 7 is shown.
  • the leg 6 extends upwards with an inclined section 60 and merges with a curvature 61 into the upper vertical web 7, the upper curvature 61 having an angle of curvature of less than 90 °.
  • the upper vertical web 7 can rest against an end edge of the top panel, which ensures improved support.
  • the roller 10 comprises a central axle opening 17 which is surrounded by a roller bearing, for example a ball bearing.
  • a plastic body made of hard plastic, for example POM, is provided around the roller bearing and forms the surface 11.
  • the surface 11 is formed between two radially protruding rings 12 and 13.
  • At least one track 4, 5 of the guide rail can also be coated for particularly good rolling behavior.
  • a coating of the surface 11 of the roller 10 is also possible.
