Abstract

A restraint apparatus configured to selectively attach a flexible hose at an outlet structure of a manifold of an air conveyance system is provided. The restraint apparatus includes a restraint member having a flat, planar shape. The restraint member includes a first opening located at a first end and a second opening located at a second end opposite the first end. The first and second ends of the restraint member are configured to be biased toward each other such that the first opening is operable to receive the outlet port therethrough and the second opening is operable to receive the hose therethrough. Upon release of the first and second ends of the restraint member, the first and second ends are operable to exert a bias force against the outlet structure and the hose, respectively, in a manner that resists removal of the hose from the outlet structure.

Claims

1. A forced air conveyance system for a granular material, comprising:

a distribution head having an inlet in communication with a plurality of outlet ports each extending through an outlet structure;

a plurality of hoses each configured to be inserted into one of the plurality of outlet ports of the distribution head; and

a restraint member having a first opening located at a first end and a second opening located at second end,

wherein the first and second ends of the restraint member are configured to be biased toward each other such that the first opening is operable to receive the outlet structure therethrough and the second opening is operable to receive the hose therethrough, and

wherein upon release of the first and second ends of the restraint member, the first end of restraint member is configured to bias against the outlet structure and second end of the restraint member is configured to bias against the hose in a manner operable to resist a longitudinal force directed to remove the hose from the outlet structure.

2. The system as recited in claim 1, wherein one or more of the plurality of outlet structures includes a first extension and a second extension positioned in a radial outward direction from an exterior surface of the outlet structure.

3. The system as recited in claim 2, wherein the first opening of the restraint member further includes a first cutout portion and a second cutout portion configured to receive the first and second extensions of the one or more outlet structures therethrough only when the first and second cutout portions are generally aligned at a ninety degree angle with respect to the first and second extensions.

4. The system as recited in claim 1, wherein the restraint member element is comprised of stainless steel.

5. The system as recited in claim 1, wherein the restraint member is comprised of a material composition such that upon release from biasing the first and second ends of the restraint member towards one another, the restraint member is configured to substantially return to an original shape.

6. The system as recited in claim 1, wherein a hose clamp is positioned to squeeze a top and a bottom section of the distribution head together.

7. The system as recited in claim 1, wherein a width at a center axis of symmetry of the restraint member is less than a width at one of the first and second ends of the restraint member.

8. The system as recited in claim 1, wherein the restraint member defines an edge between a central axis of symmetry and one of the first and second openings, and wherein the edge is curvilinear-shaped.

9. The system as recited in claim 1, wherein the restraint member defines an edge between a central axis of symmetry and one of the first and second openings, and wherein the edge tapers at a linear slope toward the central axis of symmetry.

10. The system as recited in claim 1, further comprising:

a delivery tool operable to distribute the granular material to a field, the deliver tool including an inlet structure configured to receive one of the plurality of flexible hoses connected to the distribution head; and

a second restraint member having a first opening located at a first end and a second opening located at second end,

wherein the first and second ends of the second restraint member are configured to be biased toward each other such that the first opening is operable to receive an inlet structure of the delivery tool therethrough, and the second opening is operable to receive one of the plurality of hoses therethrough, and

wherein upon release of the first and second ends of the second restraint member, the first end of second restraint member is configured to bias against the inlet structure and second end of the restraint member is configured to bias against the hose in a manner operable to resist removal of the flexible hose from the inlet structure of the delivery tool.
