Abstract

A scaffold system adapted for securing to a structure and for vertical movement relative to the structure, including first and second wall mounts, each of the wall mounts having a bar and a spring biasing the bar in a first direction, a slide post having a slide hook, a slide arm and a hanging pad secured to the slide arm, the slide post arranged for vertical axial movement within at least one of the first and second wall mounts, a main post having at least one post hook, a first deck fixedly secured to the main post, and a ball screw jack having a mounting plate and a lifting screw, the mounting plate secured to the first deck and the lifting screw secured to the hanging pad. The main post is arranged to complementarily fit within slide post.

What I claim is: 
     
         1 . A scaffold system adapted for securing to a structure and for vertical movement relative to the structure, the scaffold system comprising:
 first and second wall mounts, each of the wall mounts comprising a bar and at least one spring biasing the bar in a first direction;   a slide post comprising a slide hook, a slide arm and a hanging pad secured to the slide arm, the slide post arranged for vertical axial movement within at least one of the first and second wall mounts;   a main post comprising at least one post hook;   a first deck fixedly secured to the main post; and,   a ball screw jack comprising a mounting plate and a lifting screw, the mounting plate secured to the first deck and the lifting screw secured to the hanging pad, wherein the main post is arranged to complementarily fit within the slide post, the slide hook is adapted for releasable engagement with the first wall mount bar or the second wall mount bar and the at least one post hook is adapted for releasable engagement with the first wall mount bar or the second wall mount bar.   
     
     
         2 . The scaffold system of  claim 1 , wherein the first wall mount is secured to the structure at a first height, the second wall mount is secured to the structure at a second height elevationally lower than the first height and the slide hook is releasably engaged with the first wall mount bar. 
     
     
         3 . The scaffold system of  claim 1 , wherein the first wall mount is secured to the structure at a first height, the second wall mount is secured to the structure at a second height elevationally lower than the first height and the at least one post hook is releasably engaged with the second wall mount bar. 
     
     
         4 . The scaffold system of  claim 1 , wherein the first wall mount is secured to the structure at a first height, the second wall mount is secured to the structure at a second height elevationally lower than the first height, the slide hook is releasably engaged with the first wall mount bar and the at least one post hook is releasably engaged with the second wall mount bar. 
     
     
         5 . The scaffold system of  claim 1 , further comprising a third wall mount comprising a bar and at least one spring biasing the bar in a first direction, wherein the first wall mount is secured to the structure at a first height, the second wall mount is secured to the structure at a second height elevationally lower than the first height, the third wall mount is secured to the structure at a third height elevationally lower than the second height and the slide hook is releasably engaged with the first wall mount bar and the at least one post hook is releasably engaged with the third wall mount bar. 
     
     
         6 . The scaffold system of  claim 1 , further comprising a third wall mount comprising a bar and at least one spring biasing the bar in a first direction, wherein the first wall mount is secured to the structure at a first height, the second wall mount is secured to the structure at a second height elevationally lower than the first height, the third wall mount is secured to the structure at a third height elevationally higher than the first height and the slide hook is releasably engaged with the third wall mount bar and the at least one post hook is releasably engaged with the first wall mount bar or the second wall mount bar. 
     
     
         7 . The scaffold system of  claim 1 , further comprising at least one limit switch arranged to engage the hanging pad or the slide arm. 
     
     
         8 . The scaffold system of  claim 1 , further comprising a second deck positioned elevationally higher than the first deck. 
     
     
         9 . The scaffold system of  claim 1 , further comprising at least one safety lug secured to the structure and the first deck.
