Abstract
A concrete hose safety device has two stiff elongated hemi-cylindrical sections which may be half tubes or less than half, the sections having internal diameters roughly equal to the external diameter of a concrete hose. A plurality of hinge straps secure the sections in parallel and allowing them to open to allow a concrete hose to be laid therein and closed with the concrete hose secured therein. A plurality of closure straps then hold the device closed. In use, an operator may simply rely on-the device to prevent the concrete hose from whipping due to air in the hose, surge and so on.
Claims9
A concrete hose safety device for use with a concrete hose having an external diameter, the concrete hose safety device comprising:
- first and second hemi-cylindrical sections, each having a concave internal diameter substantially equal to such external diameter of such concrete hose;
- a plurality of hinge members securing the first and second hemi-cylindrical sections in parallel and allowing the first and second hemi-cylindrical sections to assume a first open position in which the first and second hemi-cylindrical sections are parallel with the internal diameters facing a first direction and also able to assume a second closed position in which the first and second hemi-cylindrical sections are parallel with the concave internal diameters facing one another;
- and
- a plurality of closure members operative to maintain the first and second hemi-cylindrical sections in the second closed position.
