Safety barricade for a roof

Claim 2

A safety construction for a roof, comprising a series of base members secured to the roof adjacent the roof edge, a support member extending upwardly from the outer end of each base member, pivotal means for connecting each support member to the respective base member whereby the support member can be pivoted with respect to the base member, locking means connected to said pivotal means for locking the support member with respect to the base member, said base member having an edge disposed generally normal to the axis of pivotal connection of the base member and the support member, said base member having at least one slot communicating with said edge and disposed diagonally with respect to said edge, said slot adapted to receive a fastener to secure the base member of the roof, said fastener being automatically removable from the base member by driving the base member inwardly in the direction of said edge, and connecting means interconnecting the lower portions of said adjacent support members, said connecting means having a substantially vertical surface to provide a substantially continuous low level parapet.

Claim 3

The structure of claim 1, and including a series of rails extending between adjacent support members and located above said connecting means, and mounting means for mounting the rails for movement in a generally horizontal direction to thereby permit the rails to be moved relative to the support members and provide an access opening for said safety railing.

Claim 4

The structure of claim 1, and including a bracket connected to the lower end of each support member, said connecting means comprising a plate supported by the brackets and extending between adjacent support members.

Claim 5

The construction of claim 3, wherein said slot includes a recess located at the inward extremity of said diagonal edge, said recess being generally parallel to said side edge.

Claim 6

The construction oF claim 4, wherein said bevelled section is located on both sides of the slot and terminates adjacent said recess.

Claim 7

A safety barricade for a roof of a building, comprising a base member to be secured to the building adjacent the edge of the roof and having an inner surface disposed contiguous to the building and having an outer surface facing away from the building, a support member extending upwardly from the outer end of the base member, pivotal means for pivotally connecting the support member to the base member whereby the support member can be pivoted with respect to the base member, and locking means for locking the support member with respect to the base member, said base member having a longitudinal side edge disposed generally normal to the axis of pivotal connection of the base member and the support member, said base member having at least one slot communicating with side edge and a diagonal edge bordering the slot and disposed diagonally with respect to said side edge, said slot adapted to receive a nail to secure the base member to the roof, said nail being automatically removable from the base member by driving the base member inwardly in the direction of said side edge, the outer surface of said base member having a bevelled section bordering said diagonal edge, whereby the head of the nail will move into the bevelled section on initial inward driving of the base member to thereby reduce the frictional contact between the head of the nail and the base member.

Claim 8

A safety barricade for a roof of a building, comprising a base member to be secured to the building adjacent the edge of the roof and having an inner surface disposed contiguous to the building and having an outer surface facing away from the building, a support member extending upwardly from the outer end of the base member, pivotal means for pivotally connecting the support member to the base member whereby the support member can be pivoted with respect to the base member, and locking means for locking the support member with respect to the base member, said base member having a longitudinal side edge disposed generally normal to the axis of pivotal connection of the base member and the support member, said base member having at least one slot communicating with side edge and a diagonal edge bordering the slot and disposed diagonally with respect to said side edge, said slot adapted to receive a nail to secure the base member to the roof, said nail being automatically removable from the base member by driving the base member inwardly in the direction of said side edge, the outer surface of said base member having a bevelled section bordering said diagonal edge, whereby the head of the nail will move into the bevelled section on initial inward driving of the base member to thereby reduce the frictional contact between the head of the nail and the base member.

Claim 9

A safety barricade construction to be used for a roof of a building having a vertical wall formed of courses of concrete blocks each block having a vertically extending recess in its end surface, comprising a series of base members secured to the vertical wall adjacent the edge of the roof, a support member secured to each base member and extending upwardly above the level of the roof, a horizontal barricade member extending between said adjacent support members to provide a substantially continuous safety barricade along the edge of the roof, bracket means to secure each base member to the concrete block wall, said bracket means having a generally vertical section and a generally horizontal section, said horizontal section disposed within a horizontal joint between adjacent courses of block and said vertical section disposed within mating recesses of adjacent horizontal blocks, said bracket means including a connecting element secured to the vertical section and extending outwardly within a vertical joint between adjacent horizontal blocks in a course, and connecting means for removably attaching said base member to said connecting element.

Claim 10

A safety barricade construction to be used for a roof of a building having a vertical wall formed of courses of concrete blocks each block having a vertically extending recess in its end surface, comprising a series of base members secured to the vertical wall adjacent the edge of the roof, a support member secured to each base member and extending upwardly above the level of the roof, a horizontal barricade member extending between said adjacent support members to provide a substantially continuous safety barricade along the edge of the roof, bracket means to secure each base member to the concrete block wall, said bracket means having a generally vertical section and a generally horizontal section, said horizontal section disposed within a horizontal joint between adjacent courses of block and said vertical section disposed within mating recesses of adjacent horizontal blocks, said bracket means including a connecting element secured to the vertical section and extending outwardly within a vertical joint between adjacent horizontal blocks in a course, and connecting means for removably attaching said base member to said connecting element.

Claim 11

The construction of claim 7, wherein said connecting element constitutes a threaded boss, and said connecting means comprises a stud extending through openings in the base member and threaded within said boss.

Claim 12

The construction of claim 7, wherein said horizontal section is on the upper edge of said bracket means and rests on the upper edges of the blocks of a course.

Claim 13

The construction of claim 7, wherein said vertical section bridges said vertical joint between adjacent blocks in a course.

Claim 14

The construction of claim 7, wherein said base member has a side edge and has at least one slot communicating with said side edge and a diagonal edge bordering the slot and disposed diagonally with respect to said side edge, said slot adapted to receive a nail to secure the base member to the roof, said nail being automatically removable from the base member by driving the base member inwardly in the direction of said side edge.
