Abstract
A securing device for securing objects with respect to spaced apart beams or the like. A rigid extensible member is provided for bridging the span between the beams and securely pressing its ends against the beams. A non-rigid support such as a chain is connected to the ends of the rigid extensible member and secures the object such that a binding force is not exerted on the midportion of the rigid extensible device. If desired, a hydraulic jack can be utilized as the rigid extensible member.
Claims5
A device for securing objects with respect to spaced apart first and second pierceable and opposed stationary surfaces comprising:
- a first piercing engagement member for engaging and piercing said first stationary surface to provide a first base secured against movement along said first stationary surface;
- a second piercing engagement member for engaging and piercing said second stationary surface to provide a second base secured against movement along said second stationary surface, said first and second engagement members being disposed along a common axis;
- spreading bar means connected to said first and second engagement members for relatively spreading said first and second engagement members to securely pierce and press each of said engagement members against a respective one of said first and second stationary surfaces wherein said spreading bar means includes a jack for spreading said first and second engagement members into said first and second stationary surfaces and providing a compression load bearing support between said first and second engagement members;
- and
- flexible suspension means extending in a single flexible span from said first to said second engagement member and attached thereto for suspending and securing an object with respect to said first and second engagement members adjacent to said first and second stationary surfaces, said flexible suspension means flexibly bearing the load of an object such that the load of an object suspended and secured to said suspension means is received as a compression load on said spreading bar means and as a load urging said first and second engagement members to move along said first and second stationary surfaces.
