Ramp construction and elements therefor
First Claim
1. Equipment comprising a number of modular elements for easing the passage of wheelchair users through abrupt differences in level by use of the driving ramp principle, wherein the equipment comprises plural first and second types of elements for modular construction of ramp formations, the first type of elements being a relatively low, wedge-shaped ramp elements with inclined upper surfaces, wherein the inclined surfaces are about 10-20°
- to horizontal and wherein greatest heights of the first type of elements is about 10-50 mm, and the second types of elements being a flat tile elements having same heights as the greatest heights of the first type of elements, and further wherein the first and second types of elements are configured as shell elements with top plates having patterns of holes having side walls extending downwards from edges of the top plates and having numbers of support studs provided on and extending downward from undersides of the top plates, and further comprising connectors having head parts and lock parts for connecting vertically aligned holes of two or more elements of either the first type and/or the second type superimposed on top of each other by inserting the connectors through the aligned holes of the superimposed elements.

Abstract
For facilitating the passage of wheelchair users over door thresholds it is known to lay out ramp elements across the threshold, this however being an expensive solution even implying that the door cannot be closed. The invention provides for a ramp set suited to be laid out at both sides of the threshold so as to leave the top side thereof uncovered, whereby the door can still be opened and closed. The ramp construction is modular based on the use of light, joinable plastic tile elements of ordinary shape and wedge shape, respectively, and this makes it possible to build up non-costly, tailored ramp constructions in more general, with an associated possibility of reusing the tile elements.

10. Equipment for easing the passage of wheelchair users through abrupt differences in level, e.g. over door thresholds, by use of the driving ramp principle, wherein the equipment comprises element parts for the module construction of ramp formations, primarily relatively low, wedge-shaped ramp elements with suitable slightly inclined upper side, such as with a wedge-angle of 10-20°
- and preferably with a greatest height of 10-50 mm, and secondary flat tile elements of the same height as the greatest height of the associated ramp elements, wherein both the ramp elements and the flat tile elements are structurally of the type which are built up as shell elements with a top shell from which edge wall parts extend downwards, and support shell parts with edge wall parts which are configured with recesses for the accommodation of assembly coupling pieces, wherein the top shells are configured with a pattern of through-going holes, wherein equipment comprises coupling pieces for the vertical fixing of elements to underlying elements by the pressing of snap-lock coupling pieces down through respectively associated holes, and wherein the vertically coupling connectors have at least two different lengths, the connectors further comprising “
long”
pieces for connecting the flat tile elements with thicker ends of the ramp elements, and “
short”
pieces for connecting thinner ends of the ramp elements with the flat tile elements.
- and preferably with a greatest height of 10-50 mm, and secondary flat tile elements of the same height as the greatest height of the associated ramp elements, wherein both the ramp elements and the flat tile elements are structurally of the type which are built up as shell elements with a top shell from which edge wall parts extend downwards, and support shell parts with edge wall parts which are configured with recesses for the accommodation of assembly coupling pieces, wherein the top shells are configured with a pattern of through-going holes, wherein equipment comprises coupling pieces for the vertical fixing of elements to underlying elements by the pressing of snap-lock coupling pieces down through respectively associated holes, and wherein the vertically coupling connectors have at least two different lengths, the connectors further comprising “
