Abstract

A load binder with an enclosed ratchet mechanism and a removable handle consists of an elongated tubular portion, a handle, a ratcheting mechanism, a first threaded shaft, and a second threaded shaft. The first threaded shaft and the second threaded shaft are rotatably engaged to a tubular body of the elongated tubular portion. However, the first threaded shaft and the second threaded shaft do not detach from the tubular body. The tension on a chain that is attached at the first threaded shaft and the second threaded shaft can be adjusted by rotating the tubular body. The ratcheting mechanism is used to control the tubular body about the first threaded shaft and the second threaded shaft. To be protected from dirt and the like, the ratcheting mechanism is enclosed. The handle, which is removable, is used to control the ratcheting mechanism.

Claims (55)

1. A load binder with an enclosed ratchet mechanism and a removable handle comprises:

an elongated tubular portion;

a handle;

a ratcheting mechanism;

a first threaded shaft;

a second threaded shaft;

the elongated tubular portion comprises a first end, a tubular body, and a second end;

the tubular body extending from the first end to the second end;

the first threaded shaft being concentrically and terminally engaged to the tubular body at the first end;

the second threaded shaft being concentrically and terminally engaged to the tubular body at the second end;

the ratcheting mechanism being rotatably mounted onto the tubular body, wherein the ratchet mechanism encircles the tubular body;

the handle being removably attached to the ratcheting mechanism, wherein the handle is used to rotate the elongated body by the ratcheting mechanism;

the ratcheting mechanism comprises an enclosed housing, a ratchet gear, a pawl, a pawl lever, and an attachment protrusion;

the ratchet gear and the pawl being positioned within the enclosed housing;

the pawl being mechanically engaged with the ratchet gear;

the pawl lever being axially connected to the pawl, wherein the pawl lever is used to engage and disengage the pawl with the ratchet gear;

the pawl lever extending outwards from the enclosed housing through a rubber ring; and

the attachment protrusion being externally mounted onto the enclosed housing.

2. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 1 further comprises:

the elongated tubular portion further comprises a first opening, a second opening, a first set of internal threads, and a second set of internal threads;

the first opening concentrically traversing into the tubular body at the first end;

the second opening concentrically traversing into the tubular body at the second end;

the first set of internal threads traversing into the tubular body from the first opening adjacent to the first end; and

the second set of internal threads traversing into the tubular body from the second opening adjacent to the second end.

3. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 2 further comprises:

the first set of internal threads spiraling in a first helical direction; and

the second set of internal threads spiraling in a second helical direction, wherein the second helical direction is opposite of the first helical direction.

4. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 2 further comprises:

the first threaded shaft and the second threaded shaft each comprise an externally threaded portion, a shaft body, and an attaching end;

the shaft body extending from the externally threaded portion to the attaching end;

the externally threaded portion of the first threaded shaft being rotatably engaged with the first set of internal threads; and

the externally threaded portion of the second threaded shaft being rotatably engaged with the second set of internal threads.

5. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 2 further comprises:

the elongated tubular portion further comprises a first stop and a second stop;

the first stop being integrated into the first set of internal threads at the first end; and

the second stop being integrated into the second set of internal threads at the second end.

6. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 1 further comprises:

the handle comprises an engagement block and a handle body;

the engagement block being terminally connected to the handle body; and

the engagement block being removably attached to an attachment protrusion of the ratcheting mechanism.

7. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 6 , wherein the engagement block is removably attached to the attachment protrusion with an interlocking mechanism.

8. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 1 further comprises:

a first attachment member;

a second attachment member;

the first attachment member being connected to the first threaded shaft at an attaching end of the first threaded shaft; and

the second attachment member being connected to the second threaded shaft at an attaching end of the second threaded shaft.

9. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 8 further comprises:

a first intermediary chain link;

a second intermediary chain link;

the first attachment member being connected to the attaching end via the first intermediary chain link; and

the second attachment member being connected to the attaching end via the second intermediary chain link.

10. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 8 , wherein the first attachment member and the second attachment member are attachment hooks.

11. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 8 , wherein the first attachment member and the second attachment member are U-shaped handles.

12. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 8 , wherein the first attachment member and the second attachment member are attachment rings.

13. The load binder with an enclosed ratchet mechanism and a removable handle as claimed in claim 1 , wherein the ratcheting mechanism is centrally mounted onto the body.
