Title (EN) INTERLOCKING PAVING STONE FOR COVERING THE GROUND AND THE LIKE
(FR) PIERRE DE PAVAGE A EMBOITER UTILISEE POUR RECOUVRIR LE SOL ET ANALOGUE
Abstract:
(EN) An interlocking paving stone (10) which has a twelve-sided main section (12) and an eight-sided tail section (14) which are integral with each other, coplanar, and symmetrical about a longitudinal plane (60) perpendicular to the paving stone which bisects it into two equal longitudinally extending sections. The relationship of the lengths of the sides to each other and angles they define are such that a large number of different interlocking patterns are possible which exhibit a high degree of interlock along both opposite edges and both opposite ends of the stones.
(FR) Pierre de pavage à emboîter (10) présentant une partie principale à douze faces (12) et une partie arrière à huit faces (14) solidaires l'une de l'autre, coplanaires et symétriques autour d'un plan longitudinal (60) perpendiculaire à la pierre de pavage qui le coupe en deux parties égales s'étendant longitudinalement. Les relations entre les longueurs des faces les unes par rapport aux autres et les angles qu'elles définissent sont tels qu'un grand nombre de différentes configurations d'emboîtement sont possibles, lesquelles présentent un degré élevé d'emboîtement le long des deux bords opposés et des deux extrémités opposées des pierres.
