Definitions

  • the present invention relates to a telescopic rail an extending table.
  • the telescopic rail is part of one Fitting with which the divided tabletops of the Extending table in their respective more or less separate position can be locked.
  • Extending tables have split one or more times Table tops. When pulling the table tops apart prepared insert plates are placed between them and the overall table top surface accordingly be enlarged.
  • EP 0 901 760 A1 describes a pull-out rail for one Extending table known.
  • the pull-out rail has a double-T profile as an internal management profile that is most stationary Table part of the extending table is attached.
  • the jetty of this Double T profile is designed as a hollow profile.
  • Lateral, arched cantilever arms at the top and bottom of this Ridges form curved bearing surfaces for ball bearings.
  • the inner contact surfaces of these ball bearings are on the Flanges formed a C-profile.
  • These C profiles can be moved along the guide profile.
  • the C-profiles are on the extendable table tops attached.
  • the freely accessible ball bearings can absorb radial and axial forces. However, it is Stress on the bearing surfaces in the cantilever arms of the double-T profile and the flanges of the C-profile the higher, ever Roll the balls in the bearing surfaces less flat.
  • the invention has for its object an improved Specify telescopic rail of an extending table.
  • the roller bearings in the installed state protected from the outside, because the Rolling bearings from the web and the flanges of the respective C-profile completely covered from the side and from the outside become.
  • the risk that the rolling bearings by external Intervention could be damaged is therefore practical not given.
  • the design of the roller bearings as cylindrical roller bearings has the advantage that occurring forces over a larger area can be transferred without being expensive arched storage areas would have to be provided.
  • the one in the C-profile or double-T profile trained Storage areas can thus be easy to manufacture flat U-groove can be provided. Due to the smaller surface pressure with comparable forces can a material that is specifically softer than steel for the Double-T profile and for the C-profiles can be used. So has become the use of aluminum materials Material for the double T profile and the C profile as highlighted economically.
  • the Hollow section has the advantage that support rollers from the inside can be easily screwed to the outside of the web can.
  • the support rollers are preferably in the end region of the Double T profile available. These support rollers roll on the Inner surfaces of the C-profiles and fully stabilize it extended C-profile on the double-T profile. At maximum When the table top is pulled out, the upper support roller becomes extreme strains when resting on the table top, while the lower support roller is extremely loaded when the table is lifted on the extended table tops.
  • the Support rollers can be assigned so that they too in the bearing surfaces of the C-profiles used for the cylindrical rollers are trained, can roll.
  • Double T-profile Inside the web designed as a hollow profile from Double T-profile can accommodate furnishing parts be used to lock the tabletops in their differently extended position back and forth can be moved.
  • An extension table not shown, has a fixed table part 12 and an extendable table top 14.
  • a telescopic rail 15th By means of a fitting that a telescopic rail 15th has, can in each case on the telescopic rail 15th attached table top 14 in the longitudinal direction Move telescopic rail 15. The table becomes too an extending table.
  • the telescopic rail 15 has a double T profile 100.
  • the web 102 formed as a hollow profile of this double-T profile 100 is stiffened by transverse walls 104, 106, 108.
  • At the top and the lower cross-sectional area of the web 102 are cantilever arms 110, 112 and 114, 116 cantilevered.
  • the tops or have the undersides of the cantilever arms 110 a U-groove 122, which serves as a bearing surface for a respective Cylindrical roller bearings 123 and 124 are used.
  • the two lateral shoulders 121, 125 of each U-groove 122, 124 prevent the cylindrical roller bearings from migrating sideways.
  • the C-profiles 130, 132 are like the double-T profile 100 manufactured as continuous castings. they consist of an aluminum material.
  • Flanges 136, 138 have their respective inner surfaces a U-groove 142, the size of the U-groove 122 of the Cantilever arms correspond to 110 to 116.
  • the cylindrical roller bearings 123, 124 thus roll in the U-grooves 122, 142, which in the cantilever arms 110 to 116 and the flanges 136, 138 available.
  • the upper flange 136 of both C profiles has one outward-pointing cantilever 146 to widen it To provide support for the table tops.
  • the upper and lower cylindrical roller bearings 123, 124 are connected to each other via a cage 150, which on the Inside of the web 152 from the respective C-profile 130 is positioned.
  • the cage 150 has a U-shaped middle turn 154 so as not to use a rope or a Collide roller chain.
  • Both roles 160, 162 are each in the pull-out direction in the end area of the hollow profile web 102 present on the side on the side on which C-profile 130 can be pulled out.
  • the two rolls 160, 162 are also through the web 102 through a Screw 164 attached to the web 102.
  • rollers 160, 162 run in the same U-grooves 142 that also as a tread for the cylindrical roller bearings 123, 124 To be available. Stabilize the two rollers 160, 162 the respective, maximum extended C-profile 130 or 132 on the double-T profile 100 and fix also the fitting 13 in the retracted position facilitate assembly.
  • a U-shaped one Groove 170 formed into which the hammer head one Hammer head screw 172 can be inserted.
  • the present example is about the hammer head screw 172 screwed a U-rail 174.
  • the U-rail is 174 in turn attached to the fixed table part 12.
  • the double-T profile is 100 and thus Telescopic rail 15 attached to the fixed table part 12.
  • a holding device with which a locking device to determine the respective position of the table top 14 are releasably fixed in position relative to the fixed table part 12 can.
  • These holding parts include a rotary rod 70 and one surrounding guide sleeve 80, which in the upper chamber 180th of the hollow profile web 102 find space.
  • a locking rod 22 which is also Is part of the holding device.
  • a lower chamber 184 which is delimited at the top by the transverse wall 108 is one Connection plate 25 attached to the hollow profile web 102, the so over the double-T profile on the fixed table part 12 is attached.
  • the connecting plate 25 thus set fixed abutment for the holding device.
  • the longitudinally displaceable parts of the holding device such as the Rotating rod 70 and the locking rod 22 can be inside of the hollow profile web 102 are longitudinally displaceable.
  • the rotary rod 70 and the locking rod 22 are in turn in a manner not shown in FIG. 3 on the extendable table top 15 attached.
