Definitions

  • the invention relates to an adjustable support, in particular a height-adjustable floor supports for system floors, such. Double, exhibition or assembly floors according to the preamble of claim 1.
  • a height-adjustable support member which consists of two about a common axis relative to each other rotatable parts, wherein the facing sides have helically coiled concentric and the same slope having complementary surface areas which extend substantially around the entire circumference of the parts.
  • the surface areas of the first part in this case have a groove, while the surface areas of the second part have a spring which cooperate to guide the two parts against each other.
  • a floor support consisting of two base elements having a plurality of pairs of complementary helical pitch passages extending along the outer edge of the floor support. Between the pitch passages, a recess is provided in the one base element and a guide pin in the case of the other base element, so that the base elements can be inserted into one another via guide pins and recess in order to guide the elements against one another.
  • Such supports are preferably used to support subsequently or temporarily constructed system floors, such as elevated exhibition floors for events, shop fittings, office equipment, in showrooms and as raised floors on exhibition stands. They have the advantage that they can be set up quickly and have a high load capacity.
  • the known supports have the disadvantage that the production is relatively expensive, since several molds for the preparation of the individual parts of the supports are necessary.
  • the structure of the supports is relatively time-consuming, as always a matching element must be at hand for an element.
  • An adjustable support in particular a height-adjustable floor support for system floors, such as double, exhibition or mounting floors consists at least of a first and a second base member which are at least partially plugged into each other and rotatable about a common axis.
  • the first and the second base element in the nested state with each other facing sides are based on each other and by the rotation of the base elements against each other, the length of the support for height adjustment of a system base is changeable.
  • the first and the second base element each have at least two outer wall parts, each with a helically wound surface region having an incline, wherein the surface regions of the outer wall parts each extend on the mutually facing sides of the base elements and are complementary to the surface regions of the respective other base element, in such a way that, in the assembled state of the base elements, the surface areas of a base element for supporting the base elements can be brought into abutment against the surface areas of the respective other base element.
  • the outer wall parts of the first and the second base element each enclose at least one recess and have, on the surface areas adjacent, inner guide surfaces for guiding the base elements in the nesting and twisting.
  • the first and the second base element each have at least one guide element which cooperates with the inner guide surfaces of the respective other base element for guiding the base elements and the first and the second base element have an identical structure.
  • first and second base elements are identically constructed or, in other words, congruent, it is possible to produce both basic elements of a support with the same casting tool. As a result, the manufacturing cost is significantly reduced, since only one type of casting tool must be provided. Since each base element can interact with each other, a quick set-up is possible since it is not necessary to search for a corresponding counterpart for a base element.
  • both base elements have an inner and an outer-part.
  • the first and the second base member each have in the recess at least one helical pitch gear with an outer guide surface, wherein the at least one pitch gear forming at least one guide element of a base member, such that the outer guide surfaces of the pitch gear a base element with the inner guide surfaces of the outer wall parts of the respective other base element cooperate.
  • each pitch passage of a base member has a pitch surface portion having a pitch complementary to a pitch surface area of a pitch gear of the other base member such that in the mated condition of the base members, a pitch surface area of a base member for supporting the base members can be brought together in abutment to a pitch surface area of a pitch gear of the respective other base element.
  • the base elements are supported not only on the surface areas of the outer wall parts, but also a support on the slope surface areas of the pitch transitions of the base elements takes place.
  • the pressure load of the individual surface areas is substantially reduced, so that a very high load capacity of the support is made possible.
  • the outer wall parts and / or the pitch threads have abutment surfaces which cooperate with the abutment surfaces of the respective other base element, such that two cooperating abutment surfaces of the base elements abut each other in a starting position of the support in which the length of the support is minimal ,
  • the stop surfaces By providing the stop surfaces, it is possible to move the support by rotation of the base elements in the starting position, without paying attention to the angle of rotation of the base elements to each other.
  • the support when using the support as a floor support of a system floor, in which all floor supports are used in the minimum position, a particularly simple and quick construction is possible because the supports are quickly displaceable to the starting position in which they have the minimum length.
  • each base element may comprise at least one stop means, which cooperates with a stop means of the respective other base element, wherein in an end position of the support in which the length of the support is maximum, two stop means of the base elements abut each other.
  • the supports can be brought into the end position in which the maximum length of the support is reached, without the base elements are rotated during rotation against each other and separate from each other. In the rotation of the base elements against each other thus falling apart of the support is prevented, so that a secure construction is ensured.
  • the support can thus be adjusted even in the loaded state, without the risk that the support falls apart during the turning process.
  • the end position of the supports can be adjusted without paying attention to the angle of rotation of the base elements relative to one another, so that, for example, floors which exclusively use supports of the maximum length as floor supports can be constructed in a particularly simple and rapid manner.
  • the invention can provide in an advantageous manner that the stop means is arranged on the inner guide surface of an outer wall part, wherein preferably the stop element simultaneously forms a guide element of the base element. Due to the dual function of a stop means as an end stop and at the same time guide element, a particularly simple construction of a base element is ensured.
  • a stop means may be arranged on one of the pitch gears or all pitch gears.
  • the pitch gears each have an inner second guide surface, and another guide element is arranged on the pitch gears, wherein the further guide element cooperates with the other guide surfaces of the respective other base member.

  • the toothing has the advantage that there is a discrete division, so that two adjacent supports always have the same length by rotation of the base elements against each other at the same angle.
  • the toothing helps to set the same length for adjacent supports, since the number of tooth jumps when turning the base elements from the starting position can be determined by the tooth jumps are optically counted or that with a jump of a tooth on the next tooth the corresponding typical " Rattling noise "is counted.
