Definitions

  • the invention relates to a roller guide device for an elevator sliding door according to the generic term of Claim 1.
  • Roller guides for sliding doors without barrel damping are for example from US 3,460,189 and US 4,642,844 known.
  • US 3,460,189 discloses a simple one Roller assembly to be manufactured for a garage door.
  • the Roller assembly is designed as a sheet metal structure and includes a thru axle and one piece Metal sheet-shaped roller with a roller bearing the thru axle is mounted. Notes, the roller in the To be designed with a view to smooth running are not contain.
  • a roller guide is one Elevator sliding door known, in which the roller Vibration-insulated from the elevator door assemblies is.
  • a vibration absorbing insert ring is firmly in the hub bore of the roller is pressed in and is together with the massive metal roller on the outer ring of a rolling bearing.
  • a longer stay in the This castor type leads to standstill positions unwanted flattening of the vibration damping Insert rings. These flattenings in turn generate a non-circular rolling behavior, which increases wear and tear great uneven running when moving the elevator sliding door conditionally.
  • EP-PS 478 938 is a roller guide for one Elevator sliding door became known for improving For smooth running, the castors have elastic inserts.
  • the inserts consist of non-metallic, hard elastic Material. To flatten the elastic inserts too avoid the treads in the Standstill positions relieved. This happens through attached to the side of the guide rail Roll lifting devices. These are as ramp pieces, with a ramp and a horizontal part. The Edge disks of the rollers enable opening the ramp sections and relieving the tread.
  • the invention has for its object a Roller guide for an elevator sliding door at the entrance to propose the type mentioned, whose disadvantages do not and which is easy to run guaranteed.
  • rollers 1 shows a schematic view of a Elevator sliding door.
  • Rollers 1 consisting of roller bodies 2 with running surfaces 3 roll over a rail running surface 4 from.
  • the tread 3 has a curved, in particular convex shape.
  • the rail tread 4 has a domed, in particular concave shape and is a component a support profile 5.
  • Door leaf 30 with suspensions 11 About axes 10 and attached roller bearings 9 with the Castors 1 connected.
  • 1 is a roller and 2 is a load-bearing part of the roller 1 and as a roller body serving bowl-shaped ring jacket, which preferably consists of thin sheet steel and its Tread 3 over a provided with a layer of fat Rail running surface 4 rolls.
  • the rail tread 4 and a support profile 5 form a guide rail 6.
  • the Roller body 2 of the roller 1 is dimensioned so that the spring action only in the elastic area of the sheet is claimed.
  • the thickness of the steel sheet of the Roller body 2 is approximately, depending on the weight of the door panel (from 20 kg to approx. 100 kg), between 0.2 mm and 1 mm.
  • Around To achieve an optimal spring effect is the radius of the Rail running surface 4 slightly larger than the radius of the Tread 3 of the roller body 2.
  • the roller body 2 has like the shape of one cut perpendicular to the axis Torus.
  • the open side 7 additionally simplifies the Production.
  • a hub 8 of the roller 1 is also from the Ring casing formed so that roller body 2, tread 3 and Hub 8 represent a one-piece sheet metal part. With the hub 8 the roller 1 is pressed onto a roller bearing 9. in the Area of this hub 8, the steel sheet is dimensioned such that ensures a good press connection to the rolling bearing 9 is. This is pressed onto an axis 10.
  • a suspension 11 has a bore 12 at its upper end to carry out the axis 10.
  • the axis 10 is pressed on or welded to the suspension 11. It is also possible, the roller body 2 at one end and the rolling bearing 9 at the other end of the axis 10. In this case is the roller bearing 9 pressed onto the axis 10 in the Drill hole 12 of the suspension 11.
  • FIG. 3 shows a second variant, in which one Guide rail 15 a cavity 16 with a slit-shaped opening 17 forms downwards.
  • the Guide rail 15 consists of two bowl-shaped Support profiles 18.
  • the support profiles 18 are on their, the Ends 17 forming ends bent so that a trough-shaped rail running surface 19 is formed.
  • About the Rail running surface 19 rolls one out of two roller bodies 20 existing roller 21 with a centrally inflated Tread 22.
  • the two roller bodies 20 serve as load-bearing parts of the rollers 21 and each have an open Page 23 to increase the spring effect and the Simplify manufacturing.
  • An opening 24 in the door leaf 30 offers space for a roller bearing 25. This roller bearing 25 will pressed onto an axis 26 on which the roller body 20 are attached.
  • the roller body 20 each have a hub 27 on. After attaching the axis 26 to the door leaf 30 the hub 27 of the roller body 20 on the axis 26 pressed on.
  • the roller body 20 are arranged so that their open sides 23 face each other and such the centrally raised tread 22 is formed.
