Apparatus for holding a first object or objects in a fixed position relative to a second object comprising an elongated continuous length strap for engaging and holding the first object; strap attachment apparatus connected to opposite ends of the strap for attaching the strap to the second object; winch-type strap tightening apparatus operatively associated with an intermediate loop portion of the strap for adjustably tensioning the strap; the winch-type strap tightening apparatus comprising a rotatable split shaft assembly for winding and unwinding the strap to adjustably tension the strap defining a slot for receiving an intermediate, variable length loop portion of the strap to enable adjustment of the effective length of strap; ratchet apparatus associated with the shaft assembly for releasably holding the shaft against unwinding rotation during and after tensioning of the strap; a one piece frame member for supporting the shaft assembly and the ratchet apparatus; and the split shaft assembly comprising a pair of elongated members having an arcuate cross-sectional configuration held in radially spaced relationship by a spacer device at one end and arcuate slots in the ratchet apparatus at the other end.

In 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; an elongated frame means having a pair of elongated spaced parallel side plate members having coaxial aligned bores for rotatably mounting said rotatable shaft means; said rotatable shaft means comprising a pair of elongated split shaft members extending between 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 coaxial aligned bores in 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; 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, the invention of assembly and mounting means for said shaft means and said ratchet means comprising: each of said shaft members having a segmental circular cross-sectional configuration of less than 180°with inner and outer arcuate peripheral surfaces extending between said side wall portions and through said coaxial aligned bores, the outer arcuate surfaces having a radius approximately equal to the radius of said coaxial aligned bores; a pair of circumferentially spaced arcuate slots in said ratchet wheel member having radii approximately equal to the radii of the arcuate inner and outer surfaces of said split shaft members and being coaxial therewith; a first end portion of each split shaft member being received in and confined and held in spaced relationship by one of said arcuate slots; radially extending flange means on said first end portion of each split shaft member axially adjacent said ratchet wheel member for limiting axial displacement of said split shaft members relative to said ratchet wheel member and for holding said ratchet wheel member on said split shaft members between said flange means and the adjacent side surface of one of the side plate members; a spacer means having a radially extending opening therein and being mounted between the opposite second end portions of said split shaft members for holding the opposite second end portions in uniformly spaced coaxial relationship with said arcuate slots and having a radial extending abutment surface for abutting engagement with the adjacent side surface of the other one of the side plate members to limit axial displacement of the split shaft assembly; said elongated handle member being slidably mounted in and extending through the aligned radially extending bores in the opposite end portions of said split shaft members and through said radially extending opening in said spacer means and limiting axial relative axial displacement between said spacer means and said split shaft members; and retaining means on opposite end portions of said handle member for preventing removal of said handle member from said aligned bores in said split shaft members.
