The invention claimed is: 1. A safety assembly for an edge of a roof of a building comprising: an upright having a free bottom end, the upright extending essentially vertically in its operative position and located beyond the edge of said roof, thereby defining the boundary of said roof, and wherein said upright is equipped for joining a railing thereto; a first bearing surface located at said free bottom end of said upright, an arm joined to said upright and having a free end extending downwards therefrom; a second bearing surface located at said free end of said arm; said second bearing surface for bearing against a wall of said building; securing means designed to engage on an edge of a roof or gutter from below while said first bearing surface of said upright engages from above, said securing means being adjustable in a horizontal direction with respect to said first bearing surface, wherein said securing means comprises an auxiliary arm having an engagement surface, and wherein said auxiliary arm is hingedly joined at a point to said arm, and said engagement surface of said auxiliary arm is above the point which the auxiliary arm hinges; and a beam extending between said upright and said arm. 2. The safety assembly according to claim 1, wherein said securing means can be moved between a securing and a non-securing position. 3. The safety assembly according to claim 2, wherein said securing means comprise locking means that can be operated for fixing in the non-securing position. 4. The safety assembly according to claim 1, wherein there are driving means that drive the securing means into a securing position. 5. The safety assembly according to claim 1, wherein a distance in the horizontal direction between the first and second bearing surface is adjustable. 6. The safety assembly according to claim 1, wherein a distance in the vertical direction between the first and second bearing surface is adjustable. 7. The safety assembly according claim 1, wherein said first bearing surface comprises a wheel. 8. The safety assembly according to claim 1, which is constructed such that it can be nested with other correspondingly constructed safety assemblies for the edge of a roof. 9. A system comprising a number of safety assemblies for the edge of a roof with railing fitted between each of the safety assemblies, each safety assembly comprising: an upright having a free bottom end, the upright extending essentially vertically in its operative position and located beyond the edge of said roof, thereby defining the boundary of said roof, and wherein said upright is equipped for joining a railing thereto; a first bearing surface located at said free bottom end of said upright, an arm joined to said upright and having a free end extending downwards therefrom; a second bearing surface located at said free end of said arm; said second bearing surface for bearing against a wall of said building; securing means designed to engage on an edge of a roof or gutter from below while said first bearing surface of said upright engages from above, said securing means being adjustable in a horizontal direction with respect to said first bearing surface, wherein said securing means comprises an auxiliary arm having an engagement surface designed to engage from below on an edge of said roof or gutter, and wherein said auxiliary arm is hingedly joined at a point to said arm, and said engagement surface of said auxiliary arm is above the point at which the auxiliary arm hinges; and a beam extending between said upright and said arm. 10. System according to claim 9, wherein said railing comprises a fencing-like V-shaped kinked barrier.
