Abstract
A flat lifting device includes an outer and an inner hollow section rail with closed cross section and with a substantially greater width than a thickness. One of the section rails is acted upon by a drive unit having a linearly moveable drive member for shifting the one section rail relative to the other section rail. Opposing surfaces of the outer and inner section rails are preferably provided with meshing profiles which extend in moving direction of the slideable section rail.
Claims30
A flat lifting device, in particular for pieces of furniture or the like;
- comprising:
- an outer hollow section rail;
- an inner hollow section rail accommodated within the outer section rail, said outer and inner section rails having a closed cross section and being defined by a thickness and a width, with the width being substantially greater than the thickness;
- and
- a drive unit having an linearly moving output member which is operatively connected to one of said section rails;
- guide means in form of guide rods insertable in one of said section rails for effecting a spacing between said section rails and reducing friction during relative movement of said section rails, wherein said outer section rail has an inner surface area provided with axial grooves for securely receiving said guide rods which project beyond the inner surface area to bear upon said inner section rail.
