DETAILED DESCRIPTION OF THE DRAWINGS

(8) With reference now to the drawings, and in particular FIGS. 1 through 7 thereof, an example of the instant securing apparatus for a prosthetic leg employing the principles and concepts of the present securing apparatus for a prosthetic leg and generally designated by the reference number 10 will be described.

(9) Referring to FIGS. 1 through 7 the present securing apparatus for a prosthetic leg 10 is illustrated. The securing apparatus for a prosthetic leg 10 includes a belt strap 20 having a right end 22, a left end 24, an interior surface 26, and an exterior surface 28. A pair of hook and loop fasteners 30 includes a hook fastener 32 and a loop fastener 34, with each of the hook fastener 32 and the loop fastener 34 disposed on the interior surface 26 of the belt strap 20 proximal the right end 22 and the exterior surface 28 of the belt strap 20 proximal the left end 24, respectively. The pair of hook and loop fasteners 30 is configured to selectively secure the right end 22 to the left end 24 around a waist of a user. A pair of top attachment loops 36 includes a right top attachment loop 38 and a left top attachment loop 40, with each of the right top attachment loop 38 and the left top attachment loop 40 having a pair of top ends 42 attached to the exterior surface 28 of the belt strap 20 proximal the right end 22 and the left end 24, respectively.

(10) The securing apparatus for a prosthetic leg 10 further includes a sled-shaped support attachment 44. The support attachment 44 includes a substantially rectangular flattened base portion 46, a pair of substantially trapezoidal support extensions 48, and a pair of bottom attachment loops 50. The base portion 46 has a linear back edge 52, a right edge 54, a left edge 56, an upper surface 58, a lower surface 60, and an upwardly disposed convexly curved front area 62. A gripping member 64 is optionally disposed on the upper surface 58 of the base portion 46 of the support attachment 44. The pair of substantially trapezoidal support extensions 48 includes a right support extension 66 and a left support extension 68, with each of the right support extension 66 and the left support extension 68 having a top surface 70, an exterior side surface 72, and a bottom surface 74 medially disposed on the upper surface 58 of the base portion 46 adjacent to the right edge 54 and the left edge 56, respectively. Each of the pair of support extensions 48 is perpendicularly disposed to the base portion 46. The pair of bottom attachment loops 50 includes a right bottom attachment loop 76 and a left bottom attachment loop 78, with each of the right bottom attachment loop 76 and the left bottom attachment loop 78 having a pair of bottom ends 80 attached to the exterior side surface 72 of each of the right support extension 66 and the left support extension 68, respectively, proximal the top surface 70.

(11) Each of a right ratchet strap 81 and a left ratchet strap 82 of a pair of ratchet straps 84 has an upper end 86, a lower end 88, a rearward facing upper spring-loaded clip 90 attached to the upper end 86, and a frontward facing lower spring-loaded clip 92 attached to the lower end 88. The upper spring-loaded clip 90 of each of the right ratchet strap 81 and the left ratchet strap 82 is removably attachable to the right top attachment loop 38 and the left top attachment loop 40, respectively. The lower spring-loaded clip 92 of each of the right ratchet strap 81 and the left ratchet strap 82 is removably attachable to the right bottom attachment loop 76 and the left bottom attachment loop 78, respectively, of the support attachment 44. Lastly, an expandable strap 94 has a right loop 96 and a left loop 98, with each of the right loop 96 and the left loop 98 slidably disposed around the right ratchet strap 81 and the left ratchet strap 82, respectively, proximal the lower end 88. The support attachment 44 selectively supports a foot portion 100 of a prosthetic leg 102 between the pair of support extensions 48 when the pair of ratchet straps 84 attaches the support attachment 44 to the belt strap 20.

(12) The securing apparatus for a prosthetic leg 10 optionally includes a second top attachment loop 104 having a pair of second ends 106 attached to the exterior surface 28 of the belt strap 20 proximal the right top attachment loop 38.
