## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The concrete hose safety device of claim 1, wherein the hinge members further comprise:
a plurality of flexible straps, each strap having first and second ends secured to the respective first and second hemi-cylindrical sections.

### Claim 3 (depends on 1)

The concrete hose safety device of claim 1, wherein the closure members further comprise:
a plurality of flexible straps, each strap having first and second ends, the first end secured to the first hemi-cylindrical section and the second end able to operatively engage a fastener secured to the second hemi-cylindrical section.

### Claim 4 (depends on 3)

The concrete hose safety device of claim 3, wherein the fastener further comprises a buckle;.

### Claim 5 (depends on 1)

The concrete hose safety device of claim 1, further comprising a length of the first and second hemi-cylindrical sections, wherein the length is at least 6 feet.

### Claim 6 (depends on 1)

The concrete hose safety device of claim 1, wherein the internal diameter is one member selected from the group consisting of: 3 inches, 4 inches, 5 inches, and combinations thereof.

### Claim 8 (depends on 1)

The concrete hose safety device of claim 1, wherein the material of the hemi-cylindrical sections is polyvinylcarbonate, PVC.

### Claim 9 (depends on 1)

The concrete hose safety device of claim 1, wherein the material of the hemi-cylindrical sections is one member selected from the group consisting of: metal, high strength polymer, composites, and combinations thereof.

### Claim 9 (depends on 3)

The concrete hose safety device of claim 3, further comprising:
a flexible handle secured to one flexible strap.
