Abstract
A work scaffold having a platform and leg assemblies rotatably attached to each end of the platform. The platform may have a handle connected to free end that extends out the sides of the platform, which engage with links attached to the leg assemblies and the platform to lock the scaffold in an open or closed position. The platform may have hooks that extend out beyond the ends of the platform from under the platform so a second work scaffold can be situated on the hooks. The platform may be formed of boards with holes that receive cross members. A method for using a work scaffold. A method for forming a work scaffold.
Claims4
A work scaffold comprising:
- a platform;
- a first kg assembly moat lye attached in proximity to a first end of the platform;
- a second leg assembly rotatably attached proximity to a second end of the platform;
- and
- a latch assembly which locks the first leg assembly in an open position where the first leg assembly forms an angle between 30° and 125° with the platform so a user can be supported on the scaffold when standing on the scaffold, and unlocks the first leg assembly from the locked position so the first leg assembly can rotatably move into a closed position where the first leg assembly is folded up to the platform and is essentially in parallel with the platform, the latch assembly having a latch handle and a first latch bracket attached adjacent a first side of the platform and a second latch bracket attached adjacent a second side of the platform, the latch handle having a generally U shape formed by a center portion and a first arm and a second arm which extend from either side of the center portion, the first arm held to the platform by the first latch bracket and the second arm held to the platform by the second latch bracket, the first arm having a free end which extends through a first platform slot in the first side of the platform, the latch assembly having a first spring which biases the free end towards a top of the first platform slot in the open position, the platform having a first latch bolt extending outwards from the first side, a first link with a link slot, the first link, attached to the front kg assembly with a first latch bolt disposed in the first link slot to hold the first link to the first side of the platform, as the first leg assembly moves relative to the platform, the first link slot moves along the first latch bolt until the first, latch bolt is disposed at a far end of the first link slot when the scaffold is in the open position, and the first latch bolt is disposed at a rear end of the link slot when the scaffold is in the closed position, the free end of the first arm extends out of the first platform slot and blocks the first link from moving and thus locks the first leg assembly in the open position, when the handle is moved up, the first arm moves down in the first platform slot allowing the first link slot to move along the first latch bolt and thus the first link to move to the folded position, when in the folded position, the first link holds down the free end with the first latch bolt disposed in the rear end of the link slot, which holds the handle up towards the platform so the handle will not catch on an object when the scaffold is being moved.
