Definitions

  • the present invention relates to a telescopic rail of an extension table.
  • the telescopic rail is part of a fitting with which the divided table tops of the extension table can be locked in their respective more or less separated position.
  • Extension tables have one or more split table tops. When pulling apart the table tops prepared insert plates can be placed between them and thereby the total desktop surface can be increased accordingly.
  • the drawer rail has a double T-profile as an inner guide profile, which is attached to the stationary table part of the extension table.
  • the web of this double T-profile is designed as a hollow profile.
  • Lateral, arcuate cantilevers at the top and bottom of this bridge each form arched bearing surfaces for ball bearings.
  • the inner bearing surfaces of these ball bearings are formed on the flanges of a C-profile.
  • These C-profiles can thereby be moved along the guide profile.
  • the C-profiles are each attached to the extendable table tops.
  • the freely accessible ball bearings from the outside can absorb radial and axial forces.
  • the stress on the bearing surfaces in the cantilevers of the double-T profile and the flanges of the C-profile the higher the less area the balls roll in the bearing surfaces.
  • a generic telescopic rail of an extending table is known from the US-A-4,470,642 a kinematic device for drawers.
  • the telescopic rail has a kind of double-T-profile, the upper, flange-like structure is centrally surrounded by a C-profile, the C-profile is mounted and guided longitudinally adjustable cylindrical roller bearings on this structure.
  • the present invention seeks to provide an improved telescopic rail of an extension table.
  • the C-profile is arranged laterally on the double-T-profile and aligned with its upper and lower flange to the web of the double-T-profile.
  • rollers acting as support rollers preferably in the end region of the double-T-profile is provided. These rollers roll on the inner surfaces of the C-profiles and stabilize the fully extended C-profile on the double T-profile.
  • the upper roller is subjected to extreme stress when being supported on the table top, while the lower roller is then subjected to extreme load when the table is lifted by the extended table tops.
  • the Casters can be assigned so that they can also roll in the bearing surfaces of the C-profiles, which are designed for the cylindrical rollers.
  • the double-T-profile can be attached to the fixed table part of the extension table with the help of a hammer head screw.
  • Transverse walls in the web formed as a hollow profile of the double T-profile increase the rigidity of the web.
  • the hollow profile has the advantage that from the inside the rollers can be easily screwed to the outer sides of the web.
  • the table plate 14 fastened in each case to the telescopic rail 15 can be displaced in the longitudinal direction of the telescopic rail 15.
  • the table top 14 is not shown in detail in FIG.
  • the table becomes an extension table.
  • the telescopic rail 15 has a double-T-profile 100.
  • the designed as a hollow profile web 102 of this double-T-profile 100 is stiffened by transverse walls 104, 106, 108.
  • cantilevers 110, 112 and 114, 116 are cantilevered.
  • the upper sides or the lower sides of the cantilever arms 110 have a U-groove 122, which serves as a bearing surface for a respective cylindrical roller bearing 123 and 124, respectively.
  • the two lateral shoulders 121, 125 of each U-groove 122 prevent lateral migration of the cylindrical roller bearings.
  • roller bearings performing cylindrical roller bearings are protected when installed from the outside, since the bearings are completely surrounded by the web and the flanges of the respective C-profile from the side and from the outside. The risk that the bearings could be damaged by external interference, therefore, is practically not given.
  • the design of the rolling bearing as a cylindrical roller bearing has the advantage that occurring forces can be transmitted over a larger area, without elaborately curved bearing surfaces should be provided.
  • the trained in the C-profile or double-T profile bearing surfaces can be provided as a simple to produce planar surface U-groove. Due to the smaller surface pressure with comparable forces, a material which is specifically softer than steel can be used for the double-T profile and for the C profiles. Thus, the use of aluminum materials as a material for the double-T profile and the C-profile has been found to be economically favorable.
  • Each side of the double T-profile 100 - in the drawing left and right - each have a C-profile 130 arranged. Its height corresponds approximately to the height of the double-T profile 100.
  • the C-profiles 130, 132 are made like the double-T profile 100 as continuous castings. They consist of an aluminum material.
  • the laterally to the hollow profile web 102 directed from flanges 136, 138 have in their respective inner surface a U-groove 142, which corresponds in size to the U-groove 122 of the cantilevers 110 to 116.
  • the cylindrical roller bearings 123, 124 thus roll in the U-grooves 122, 142 which are present in the cantilever arms 110 to 116 and the flanges 136, 138.
  • the upper flange 136 of both C-profiles has an outwardly facing cantilever 146 to provide a widened bearing surface for the tabletops.
  • the upper and lower cylindrical roller bearings 123, 124 are connected to each other via a cage 150, which is positioned on the inside of the web 152 of the respective C-profile 130.
  • the cage 150 has a U-shaped central bend 154 so as not to collide with a rope or a roller chain.
  • Both rollers 160, 162 are each present in the extension direction in the end region of the hollow profile web 102 laterally on that side on which a C-profile 130 can be pulled out.
  • the two rollers 160, 162 are also secured by the web 102 through a screw 164 on the web 102.
  • the rollers 160, 162 run in the same U-grooves 142, which are also available as a running surface for the cylindrical roller bearings 123, 124.
  • the two rollers 160, 162 stabilize the respective maximum extended C-profile 130 or 132 on the double-T-profile 100 and also fix the fitting 13 in the retracted state in the correct position and facilitate the assembly.
  • a U-shaped groove 170 is formed into which the hammer head of a hammer head screw 172 can be inserted.
  • a U-rail 174 is screwed on the hammer head screw 172.
  • the U-rail 174 is in turn attached to the fixed table part 12. In this way, the double-T-profile 100 and thus the telescopic rail 15 is fixed to the fixed table part 12.
  • the upper chamber 180 of the hollow-profile web 102 is room for parts of a holding device with which a locking device for fixing the respective position of the table top 14 relative to the fixed table part 12 can be releasably fixed in position.
  • These holding parts include a rotary rod 70 and a surrounding guide sleeve 80, which find in the upper chamber 180 of the hollow-profile web 102 space.
  • a locking bar 22 which is also part of the holding device.
  • a connecting plate 25 is fixed to the hollow profile web 102, which is thus secured via the double-T-profile on the fixed table part 12.
  • the connecting plate 25 thus provided a solid abutment for the holding device.
  • the longitudinally displaceable parts of the holding device such as the rotary rod 70 and the locking bar 22, can be guided longitudinally displaceable within the hollow profile web 102.
  • the rotary rod 70 and the locking rod 22 are in turn fastened in a manner not shown on the extendable table top 15.
