Le bras 26 comporte un crochet 30 pour accrocher la partie inférieure du filet avant montage. The arm 26 has a hook 30 for hanging the lower part of the net before mounting.
Le sabot 27 ne traverse pas le mur 3a mais se trouve simplement appliqué sur ce mur par l'effet de la gravité. Le filet de protection 24 est fixé aux extrémités par des moyens de fixation appropriés non représentés. The shoe 27 does not cross the wall 3a but is simply applied to this wall by the effect of gravity. The protective net 24 is fixed at the ends by suitable fixing means, not shown.
On voit à la figure 9 un montant analogue au montant 4, muni d'un dispositif de raidissement par triangulation grace aux triangles 29 et 29d. We see in Figure 9 an amount similar to amount 4, provided with a stiffening device by triangulation through triangles 29 and 29d.
Le dispositif peut être utilisé de la façon suivante
On met en place les consoles supérieure et inférieure 1 et 2 dans les joints verticaux de la maçonnerie du mur 3. La console est maintenue en position grace à une plaquette d'appui la et à une clavette non représentee insérée dans la fente 13.The device can be used as follows
The upper and lower consoles 1 and 2 are put in place in the vertical joints of the masonry of the wall 3. The console is held in position by means of a support plate 1a and a key (not shown) inserted in the slot 13.
On accroche ensuite les montants tels que 4 à la console inférieure à l'aide d'une broche traversant à la fois les trous tels que 10 et la fente axiale 15. The uprights such as 4 are then hooked to the lower console using a pin passing through both the holes such as 10 and the axial slot 15.
On met en place les supports bloqueurs 5, 6, puis les éléments de protection tels que 19. On relève ensuite l'ensemble et fixe les montants tels que 4 aux consoles supérieures telles que 1, grace à la broche déjà décrite. En raison du fait que le montant est fixé à sa partie inférieure dans la fente axiale 15, il est possible de faire coulisser le montant pour qu'un des trous dont il est muni, vienne en regard du trou 10. The blocking supports 5, 6 are put in place, then the protective elements such as 19. The assembly is then raised and the uprights such as 4 are fixed to the upper consoles such as 1, using the spindle already described. Due to the fact that the upright is fixed at its lower part in the axial slot 15, it is possible to slide the upright so that one of the holes with which it is provided, comes opposite the hole 10.
Pour mettre en place le filet de protection 24, on accroche le montant 25 à la console 28 avec la broche déjà décrite. Le bras 26 reposant au sol, le filet 24 étant accroché à l'extrémité du bras 26 d'une part et au crochet 30 d'autre part. To set up the protective net 24, the upright 25 is hooked to the console 28 with the pin already described. The arm 26 resting on the ground, the net 24 being hooked to the end of the arm 26 on the one hand and to the hook 30 on the other hand.
On relève ensuite les bras tels que 26 avec le filet. On accroche les bras aux montants à l'aide de charrettes non représentées puis on fixe la lisse inférieure du filet sur les consoles et enfin on décroche les bras 26 qui prennent, sous l'effet de la gravité, leur position définitive en tendant le filet. Then raise the arms such as 26 with the net. The arms are hooked to the uprights using carts which are not shown, then the bottom rail of the net is fixed on the consoles and finally the arms 26 are unhooked which, under the effect of gravity, take their final position by stretching the net .
