Definitions

  • Desk comprising a desk top that is vertically adjustable within a great range
  • the present invention relates to a table having a vertically adjustable table top or an equal working plane.
  • the table is of the kind where the top is to be vertically adjustable within a great range.
  • the table comprises a motor which is engageable and disengageable for adjusting the top to a desired level within the range and a screw or the like which is operable by the motor via transmission members executing the adjustment of the top in dependence of the operation (actuation) of the motor.
  • Tables of this kind comprise a stand with telescopic legs on which the top is placed.
  • Different types of driving members such as hydraulic cylinders, electric motors, cranks, etc. are being used in connection with elevating and lowering the table top above a reference level, normally consisting of a floor or an equal ground on which the table is placed.
  • the known tables also present various transmission members, through which the table top is actuated to a desired level by means of a present driving member.
  • ⁇ ___SS_ 2 standing.
  • the requirements on the elevation adjustment function are high where there are desired big travels on elevating and lowering the table top.
  • the stability of the table top in the various side directions must be possible to maintain.
  • the need of tables with vertically adjustable tops within a wide control range appears among other things from ergonomic aspects. It is important for people who are tightly bound to their working places to be able to work in a standing as well as a sitting working position. In this connection it may be mentioned that in a standing working position the load on the back is reduced by a half relative to the case when you have a sitting working position. There is therefore a need of having a choice between a sitting and a standing working position so as to reduce the possibilities of back, shoulder and neck pains coming up.
  • the object of the present invention is among other things to solve the problems mentioned above and suggests a table construction where the travel range for elevating and Lowering the table top is outstandingly great, e.g. approx. 500 mm or more.
  • the great adjustment range can be maintained despite good stability existing in the table top in its various elevation adjusted positions.
  • the respective telescopic leg of the table consists of inner and outer profiles mutually guided by linear ball guides or so called expansion fittings.
  • the outer profile is shaped with an essentially rectangular cross section, having a ball guide with two parallel ball cages disposed at one Long side.
  • the inner and outer profiles can be guided by means of two or more parallelLy co-ordinated ball guides, whereby at Least two of the paralLelly disposed ball guides can be arranged at angles relative to each other in order to give a further increased stability in the main directions of the table top in its own plane.
  • a screw is to be arranged in or at the respective telescopic leg, the associated nut of which is fixed to the outer profile.
  • the screw follows the movements of the table top and the screw tip interacting with the transmission members is journalled in the table top.
  • Further embodiments of the inventive idea relate to specific embodiments of the inner and outer profiles. These are to be shaped in a specific way so as to journal one or more ball guides, in a suggested embodiment the ball guides being arranged at angles relative to each other.
  • the screws in or at the respective telescopic leg are driven by a common motor which preferably consists of an electric motor.
  • the driving is carried out via transmission members in the form of drive chains, the screw in a first telescopic leg being arranged to a chain wheel which is operable via a first chain from the motor.
  • Said chain wheel via a second chain, drives the screw in a second telescopic leg having a further chain wheel for said second chain.
  • the respective screw can be provided with a trapezoidal thread.
  • the travel is to be 500 mm or more, and the adjustment range is to be located within the range of 600-1200 mm relative to the floor or an equal ground.
  • the transmission members are arranged in an elongated unit and chain wheels disposed in the unit are placed at the end of the unit.
  • the unit is attachable to the under side of the table top in a way known per se, e.g. by means of screws.
  • the screws of the telescopic legs are connectable to the unit such that after attaching the unit tko the tabLe top the screws can be connected to their respective chain wheels in the unit. In this way the unit works as an easily connectable unit which during transport can accompany the table.
  • Fig. 1 in perspective obliquely from below to the right shows the table;
  • Fig. 2 in cross section shows a telescopic leg belonging to the table according to Fig. 1;
  • FIG. 3 in perspective shows driving and transmission members being parts of the table according to Fig. 1;
  • Fig 4 shows a vertical section of the table taken at one of its telescopic Legs.
  • the table according to the figures relates to a vertically adjustable table in which the table top can be adjusted within the elevation range of 650-1150 mm. In this way there is achieved a working place where the table user can optionally choose an ergonomically appropriate working position sitting as well as standing.
  • the adjustment range is chosen as great as 500 mm in order to provide for the desire to choose if the person in question wants to sit or stand working irrespective of whether the person in question is tall or short.
  • the table consists of a table top 1 being built of a framework of tightly glued Laminas generally of pine or another appropriate wood material.
  • the table top is supported by a stand consisting of two or more telescopic Legs 2.
  • the respective Leg comprises two telescopically disposed parts and by each Leg is an interposed stretcher 3.
  • a unit 4 comprising the driving means of the table.
