DETAILED DESCRIPTION OF THE INVENTION

[0026] Referring to FIG. 1 and FIG. 2, the safety stirrup according to the present invention includes a frame 1, an arm 2 and a supporting assembly 3. The frame 1 extends parallel to a first vertical plane P1 (which is shown in FIG. 5) and forms a C shape. The frame has an upper end 11 and a lower end 12, and an opening 13 is defined between the upper end 11 and the lower end 12. A pivot portion 111 is disposed at the upper end 11 while a first connecting portion 14 is disposed at the lower end 12. A strap can tie with the frame 1 to hang the stirrup at a side of a horse via a hanging hole 151 disposed on a top portion 15 of the frame 1. A bottom portion 16 of the frame 1 includes a raised portion 162 with a lightening hole 161.

[0027] As shown in FIG. 3, the first connecting portion 14 forms a hook shape and includes a first cavity 41 and a first hook 42 which extends toward an outside of the opening. Furthermore, a notch 43 is disposed in the middle of the first hook 42, and thus there are two restricting portions 44 defined on both sides of the notch 43.

[0028] The arm 2 has a length equivalent to the opening 13. One end of the arm 2 is pivotally connected with the pivot portion 111 so as to swing on the first vertical plane. The other end of the arm 2 is provided with a second connecting portion 21. As shown in FIG. 4, the second connecting portion 21 forms a hook shape and includes a second cavity 22 and a second hook 23 which extends toward an inside of the opening. Furthermore, a block 24 is disposed in the middle of the second cavity 22. The arm 2 pivots on the pivot portion 111 so that the opening 13 is opened or closed. In this embodiment, a spring 25 is disposed between the pivot portion 111 and the arm 2 to make the arm 2 be normally kept in a position which closes the opening 13. The first connecting portion 14 and the second connecting portion 21 are fitted together when the opening 13 is closed by the arm 2. In detail, the first cavity 41 of the frame 1 is inserted by the second hook 23 of the arm 2, and the second cavity 22 of the arm 2 is inserted by the first hook 42 of the frame 1. In the meanwhile, the block 24 inserts into the notch 43 and is restricted by the restricting portions 44 from laterally moving, which ensures the arm 2 only moves on the first vertical plane.

[0029] The hanging hole 151 includes an upper beam portion 152 with a thickness less than that of the top portion 15 of the frame 1. A thickness direction T of the top portion 15 of the frame 1 is defined. The upper beam portion 152 has a first end 1521 far away from the opening 13 and a second end 1522 close to the opening 13. As shown in FIG. 5, the first end 1521 is connected to a front edge 153 of the top portion 15 of the frame 1 while the second end 1522 is connected to a rear edge 154 of the top portion 15 of the frame 1. The front edge 153 is in front of the rear edge 154 in the thickness direction T. Therefore, the upper beam portion 152 extends parallel to a second vertical plane P2 which is not parallel to the first vertical plane P1. In other word, the upper beam portion 152 is skewed with respect to the frame 1 so that the stirrup, referring to FIG. 6, will rotate slightly after hanging the stirrup by a strap 10 as a result of modification of the extension of the upper beam portion 152 to facilitate putting the foot into the stirrup.

[0030] Referring to FIGS. 7, 8 and 9, the supporting assembly 3 consists of a first plate 5, a second plate 6 and a third plate 7. A groove portion 71 with an inserted portion 73 complementary to the raised portion 162 and two screw holes 72 provided on two sides of the inserted portion 73 is disposed on a bottom surface of the third plate 7. Accordingly, the groove portion 71 is fitted with the bottom portion 16 of the frame 1, and then the third plate 7 is fixed by screws which penetrate through the screw holes 72. The third plate 7 is positioned more firmly because the inserted portion 73 is inserted by the raised portion 162.

[0031] A top surface of the third plate 7 is provided with several third ribs 74. These third ribs 74 are symmetrically distributed on both sides of an imaginary midline C3 defined on the top surface of the third plate 7. There are several lower buffer spaces 75 formed between adjacent third ribs 74.

[0032] The second plate 6 is stacked on the third plate 7. The second plate 6 is soft and elastic. A bottom surface of the second plate 6 is provided with several second ribs 61. These second ribs 61 are symmetrically distributed on both sides of an imaginary midline C2 defined on the bottom surface of the second plate 6. There are several upper buffer spaces 62 formed between adjacent second ribs 61. Since shapes and positions of the second ribs 61 are corresponding to that of the third ribs 74, the second ribs 61 engage with the third ribs 74, and the upper buffer spaces 62 communicate with the lower buffer spaces 75. Air is accommodated in the upper buffer spaces 62 and the lower buffer spaces 75. The second plate 6 deforms when pressed, and the upper buffer spaces 62 deform as well, thereby cushioning the impact force.

[0033] A height of the front end 67 of the second plate 6 is greater than that of a rear end 68 of the second plate 6, so that a top surface of the second plate is angled at 5-15 degrees to a bottom surface of the second plate 6.

[0034] One side of the second plate 6 which is close to the opening 13 is provided with a shield piece 63. The shield piece 63 is adjacent to the first connecting portion 14 and is tall enough to laterally block the first connecting portion 14 and the second connecting portion 21 from being directly kicked by rider's foot, avoiding rider's foot from accidentally getting out of the stirrup. On the other hand, the second plate 6 is further provided with a supporting piece 64 opposite to the shield piece 63. The supporting piece 64 supports against the frame 1 to position the second plate 6.

[0035] A top surface of the second plate 6 is surrounded by a wall 65. The first plate 5 is stacked on the second plate 6 and abuts against the wall 65. Two inner flange portions 66 are disposed at a top end of the wall 65. Two recess portions 51 complementary to the inner flange portions 66 are provided on a top surface of the first plate 5 so that the first plate 5 is secured when the recess portions 51 and the inner flange portions 66 are fitted together.

[0036] The first plate 5 has an uniform height, but a front end 54 of the first plate 5 is higher than a rear end 55 of the first plate 5 due to the inclined top surface of the second plate 6. Referring to FIG. 10, based on a sole 8 of the rider tilting with a higher position of toes than that of a heel when tightening the muscle, the structure design of the first plate 5 in which the front end 54 is higher than the rear end 55 allows the sole 8 to be completely attached without affecting the posture.

[0037] The top surface of the first plate 5 is provided with an anti-slip portion which includes a plurality of first ribs 52. These first ribs 52 are symmetrically distributed on both sides of an imaginary midline C1 defined on the top surface of the first plate 5. Furthermore, several spikes 53 penetrate out of the first ribs 52 to facilitate slip-proofing.

[0038] One feature of this invention is that the upper beam portion 152 of the hanging hole 151 is skewed with respect to the frame 1 so that the stirrup will rotate slightly after hanging the stirrup by a strap 10 as a result of modification of the extension of the upper beam portion 152 to facilitate putting the foot into the stirrup.

[0039] Another one feature of this invention is that the supporting assembly 3 is composed of three plates and several deformable spaces so as to cushion the impact force by deformation of the second plate 6 and the upper buffer space 62 when a jumping horse lands.

[0040] Another one feature of this invention is that the supporting assembly 3 has an inclined top surface for a rider to put his foot and make the sole completely attach to the first plate 5.
