Abstract
A holding arrangement intended to hold a plate-like element to a post. The holding arrangement is provided with a peg having different cross-sections formed at two perpendicular coordinates. In a first position of rotation of the arrangement relative to the first element, the peg can be inserted into the element, and upon further rotation of the arrangement to a second position of rotation, a larger cross-section of the peg clamps the holding arrangement firmly against surfaces formed in the first element.
Claims1
A holding arrangement intended to hold a first element to a second element, comprising a first member for co-action with said first element, a second member for co-action with said second element, said first member including a peg having different cross sections formed in two perpendicular planes such that when said holding arrangement is rotated about an axis to a first position of rotation relative to said first element the peg is able to enter a slot of a recess in said first element and when said holding arrangement is rotated to a second position of rotation said peg clamps said holding arrangement to said first element, two mutually perpendicular surfaces producing a clamping force required to hold said first element and said holding arrangement together and extending perpendicular to the axis of rotation such that the clamping force is directed substantially parallel to said axis of rotation, a rear portion of said recess remote from said slot having wall surfaces which are parallel to said axis of rotation, a large cross-section of said peg clamping against said wall surfaces with a force acting perpendicular to the axis of rotation.
