Adjustable length strap tie down apparatus
First Claim
1. Apparatus for fixedly securing one object relative to another object and comprising:
- an elongated continuous length strap means for being attached to the one object and for enagaging and holding the other objects by tension;
attachment means fixedly non-adjustably connected to opposite ends of said strap means for fixedly securing the opposite ends of said strap means relative to the other object;
rotatable shaft means for winding and unwinding said strap means to adjustably tension said strap means; and
winch-type tensioning means operably associated with an intermediate loop portion of said strap for enabling adjustment of the effective length of said strap means and for enabling said effective length of said strap means and said intermediate loop portion of said strap means to be wound and tensioned and unwound and untensioned;
said winch-type tensioning means comprising;
slot means in said shaft means having a sufficient width for adjustably receiving and retaining said intermediate loop portion of said strap means;
ratchet means operably engageable with said shaft means for releasably holding said shaft means against unwinding rotation during and after tensioning of said strap means; and
said rotatable shaft means comprising;
a pair of split shaft members having mating abuttable support surfaces;
a groove formed in each of said mating abuttable surfaces; and
fastening means for holding said abuttable support surfaces of said split shaft members in abutting engagement with the grooves in oppositely spaced axial alignment to form said slot means.

Abstract
Apparatus for holding a first object or objects in a fixed position relative to a second object comprising an elongated continuous length strap means for engaging and holding the first object, strap attachment means connected to opposite ends of the strap means for attaching the strap means to the second object, and winch-type strap tightening means operatively associated with an intermediate loop portion of the strap means for adjustably tensioning the strap means, the winch-type strap tightening means comprising a rotatable shaft means for winding and unwinding the strap means to adjstably tension the strap means, slot means in the shaft means for receiving an intermediate, variable length loop portion of the strap means to enable adjustment of the effective length of strap means, and ratchet means associated with the shaft means for releaseably holding the shaft means against unwinding rotation during and after tensioning of the strap means.

5. Apparatus for fixedly securing one object relative to another object and comprising:
-
an elongated continuous length strap means for being attached to the one object and for engaging and holding the other objects by tension; attachment means fixedly non-adjustably connected to opposite ends of said strap means for fixedly securing the opposite ends of said strap means relative to the other object; rotatable shaft means for winding and unwinding said strap means to adjustably tension said strap means; slot means in said shaft means having a sufficient width for slidably adjustably receiving and retaining an intermediate loop portion of said strap means for enabling adjustment of the effective length of said strap means by varying the length of said intermediate loop portion and for enabling portions of said effective length of said strap means next adjacent said rotatable shaft means and portions of said intermediate loop portion next adjacent said rotatable shaft means to be simultaneously wound and tensioned and unwound and untensioned by rotation of said rotatable shaft means; ratchet means operably engageable with said shaft means for releasably holding said shaft means against unwinding rotation during and after tensioning of said strap means; elongated operating handle means operably connected with said rotatable shaft means for causing rotation thereof. elongated frame means having a pair of elongated spaced parallel side plate members for mounting said rotatable shaft means; said rotatable shaft means comprising a pair of split shaft members rotatably mounted in said side plate members and being spaced from one another to define said slot means and having opposite end portions extending through and rotatably supported in said elongated parallel side plate members; said ratchet means having a ratchet wheel member mounted on one juxtapositioned pair of said opposite end portions of said split shaft members and a pawl member mounted on the adjacent one of said side plate members; and said elongated operating handle means comprising an elongated operating handle member slidably mounted on the other juxtapositioned pair of said opposite end portions of said split shaft members adjacent the other of said side plate members. - View Dependent Claims (6, 7)
