Abstract
A multisided guard for guarding a space containing, for example, a hazardous operation from which personnel are to be protected. The guard comprises a plurality of vertically extending walls, each comprising a pair of upper and lower panels which are adapted to be swung from a lower position covering the space to an upper position uncovering the space.
Claims3
A safety guard for protecting a pair of adjoining intersecting vertically extending sides of a space comprising:
- a pair of vertically extending walls covering said sides,
- each of said walls including an upper trapezoidal panel having upper and lower horizontally disposed edges,
- a fixed mount,
- means hingedly supporting the upper panels of said walls to said mount for swinging movement in vertical planes about horizontally extending axes in intersecting relation,
- each of said walls including a lower trapezoidal panel hingedly secured along its upper edge to the lower edge of its corresponding upper panel, and
- a pivot pivotally securing said lower panels together adjacent their lower edges with the adjacent side edges of said upper panels and the adjacent edges of said lower panels being unsecured except at said pivot to permit each pair of upper and lower panels to be swung upwardly to substantially face to face relationship,
- the lower edge of each upper panel being longer than its upper edge, and the upper edge of each lower panel being longer than its lower edge to prevent corresponding upper and lower panels from being swung to coplanar relationship thereby facilitating swinging each of said walls from a lower to an upper position.
