Figure 1 shows a top perspective view of the assembled bail assembly 10 in a locked position, and figure 2 shows an exploded view of the components in the bail assembly of figure 1. Referring to fig. 1 and 2, the bail assembly 10 includes a bail 12 and a base portion 40. The eye 12 includes an annular portion 14, a stem portion 16, and a pair of opposed wing extensions 18a,18 b. The base portion 40 includes a collar 42, a platform 44, and a spring 46.

With particular reference to fig. 2 and 3A-3C, the loop portion 14 is attached to the stem portion 16 at a first end 16 a. The annular portion 14 is shown as being generally circular in shape. It is contemplated that the annular portion may be other shapes or sizes, such as elliptical or polygonal shapes. In one approach, the loop portion 14 is sized to receive a hook (hook) or loop. In one approach, hooks or loops are typically attached to the wire or string to assist in moving and positioning the structure.

In one embodiment, the stem portion 16 includes a shoulder 20. The shoulder 20 is attached to the annular portion 14 at the first end 16a of the stem portion 16. By properly maintaining the positioning of the ring portion, the shoulder helps handle heavier structures. The shoulder 20 of fig. 2, 3A, and 3B includes a top surface 22 and a bottom surface 24, as best shown in fig. 2. The shoulder 20 slopes outwardly from the top surface 22 to the bottom surface 24. The shoulder helps to improve movement or handling of the selected structure by virtue of the slope. It is contemplated that the shape of the shoulder may be different than that depicted in fig. 1 and 2. In another embodiment, it is contemplated that the bail assembly may not include a shoulder.

In some embodiments, the bail assembly may include at least one wing extension. For example, the eye assembly may include a continuous wing extension that encircles the pole portion at the second end of the pole portion.

The eye assembly can include a plurality of wing extensions, such as a pair of wing extensions 18a,18b shown in fig. 2 and 3A-3C. The pair of wing extensions 18a,18b are attached to the second end 16b of the rod portion 16. The pair of wing extensions 18a,18b extend outwardly from the rod portion 16. The wing extensions 18a,18b help secure the bail assembly 10 in the locked position, as will be discussed below. The shape of the pair of wing structures may be different than that depicted in fig. 2 and 3A-3C.

In one embodiment, the components of the bail assembly may be an integrally formed assembly. In another embodiment, the bail assembly may be made of two or more members that are fixedly attached to each other.

Referring back to fig. 2, the base portion 40 is configured to receive the bail 12 therein. The collar 42 of the base portion 40 defines a first opening 50 therein. The first opening 50 is configured to receive the bail 12. Referring to fig. 4A, the base portion 40 is shown in its top view. Fig. 4B and 4C show respective cross-sectional views of the base portion 40 taken along lines 4B-4B and 4C-4C in fig. 4A.

Referring back to fig. 2, collar 42 is secured to platform 44. The platform 44 forms an opening therein, which will be discussed in detail below. The spring 46 is at least partially positioned within a second opening 74 (see fig. 5 in detail) of the platform 44. The first opening 50 and the second opening 74 of the platform 44 are in spaced communication with one another. In other words, at least a portion of the first opening 50 of the collar 42 and the second opening 74 of the platform 44 are positioned such that the bail 12 and the spring 46 act in conjunction with one another, as will be discussed in detail below. In one embodiment, the first opening 50 of the collar 42 and the second opening 74 formed in the platform 44 are substantially aligned with one another.

A first end 46a of spring 46 is attached to first end 44a of platform 44. The first end 44a of the platform 44 is on the opposite side of the collar 42. Specifically, in fig. 2, in one embodiment, a first end 46a of the spring 46 is attached to the lid bottom 60. In such an embodiment, the lid bottom 60 is a separate element and is attached to a second opening 74 formed in the platform 44. In another embodiment, the spring may be attached to a bottom surface formed within the platform. In such embodiments, the bottom surface may form an opening in a portion of the platform. In another embodiment, the bottom surface of the lid bottom or platform is in a substantially secure position.

The base portion 40 of fig. 2 includes a cover top 64. A cap top 64 is attached at the second end 46b of the spring 46. In this embodiment, the cap top 64 helps to distribute weight from the hoist ring assembly 10 more evenly over its surface. It is contemplated that in another embodiment, the spring may directly contact the bail assembly. More specifically, the spring may directly contact the second end of the rod portion of the bail.

The eye assembly may comprise one or more materials. For example, in one embodiment, the bail assembly comprises a polymeric material. Non-limiting examples of polymeric materials that may be used include polycarbonates (polycarbonates) and polyethylene terephthalate (PETs). It is contemplated that other polymeric materials may be used. In another example, the bail assembly includes a metallic material. One non-limiting metallic material that can be used to form the slings is stainless steel. It is contemplated that other metallic materials that may be used include aluminum, zinc, titanium, and alloys thereof. It is contemplated that other metallic materials may be used.

Referring to fig. 5-8, various positions of the bail assembly 10 in the process of being fixedly locked are shown. In particular, fig. 5 to 8 show the eye 12 inserted and finally locked fixedly in the base part.

Referring initially to fig. 5, the bail 12 is moved or slid in a generally downward direction (in the direction of arrow a) into the first opening 50 formed in the collar 42 of the base portion 40. The first opening 50 is configured to receive the second end 16b of the rod portion 16 of the hoist ring 12. More specifically, the first opening 50 is configured to receive the second end 16b of the rod portion 16, the second end 16b of the rod portion 16 including a pair of wing extensions 18a,18 b. In fig. 5, the spring 46 is shown in an extended position. FIG. 5 also shows that the first opening 50 is substantially aligned with the second opening 74 formed in the platform 44. The lid bottom 60 of fig. 5 is shown forming part of the second opening 74 in the platform 44. Portions of the spring 46 are shown in the second opening 74.

Referring next to fig. 6, as the bail is moved in a generally downward direction (arrow a shown in fig. 5), the spring 46 is compressed. The hoist ring 12 in this position has completed its movement in the downward direction and is now ready to be rotated in the clockwise direction (arrow B) of fig. 6. In this embodiment, the eye 12 is rotated approximately 90 degrees. It is contemplated that the bail may be designed to rotate from about 30 degrees to about 150 degrees.

The location of the suspension loop is depicted in fig. 7 after the suspension loop 12 has rotated clockwise relative to the base portion 40. At this point, downward pressure is still being applied to the eye 12, causing the spring 46 to be in the fully compressed position. After the downward pressure is released from the bail 12, the spring 46 is released and extends generally upwardly as shown in FIG. 8. The spring 46 causes the bail 12 to move generally upward. The movement of the spring 46 and hence the sling 12 in relation to arrow C is shown in figure 8.

The spring 46 in fig. 8 is in a partially extended position. Because the inner side wall of the collar 42 extends inwardly, the bail 12 is prevented or restrained from continuing in the direction of arrow C, so that the spring 46 cannot move the bail 12 further upwardly (in the direction of arrow C). More specifically, each interior sidewall of the collar 42 is configured and designed to catch and securely lock a pair of wing extensions 18a,18 b. One of the interior sidewalls 80 is best shown in fig. 6 and 7, while the other interior sidewall is on the opposite side and is not visible in fig. 6 and 7. The other interior sidewall is the same size and shape as interior sidewall 80. In one embodiment, the shape of the interior sidewalls corresponds to the respective exterior surfaces of the wing extensions 18a,18b that contact the respective interior sidewalls.

It is contemplated that the shape, size, or location of the interior side walls may be different than depicted. In another embodiment, the at least one interior sidewall may be a continuous property (continuous nature) that helps secure the at least one hinge extension.

The spring 46 maintains pressure on the wing extensions 18a,18b in the upward direction (arrow C) so that the wing extensions 18a,18b will not travel back downward (direction of arrow a). During the process of moving the structure, the weight or load of the structure pulls the bail 12 in the direction of arrow C, which further helps maintain the bail assembly 10 in the locked position.

In one approach, the process of unlocking the bail 12 from the base portion 40 may occur by performing the reverse steps described in fig. 5 through 8. Specifically, the position of the bail 12 in fig. 8 will be moved generally downward (in the direction of arrow a) and rotated in the counterclockwise direction (arrow D). After rotation in the counterclockwise direction, downward pressure will be released and spring 46 will return to the fully extended position of spring 46 of FIG. 5.

Referring to fig. 9A, bail assembly 10, including bail 12 and base portion 40, is shown secured to structure 100. In one embodiment, the eye assembly 10 may be welded to the structure 100. More specifically, in this embodiment, the platform 44 of the base portion 40 is fused to the structure 100.

Referring to fig. 9B, the eye assembly 110 is shown secured to the structure 100 via fasteners. Bail assembly 110 includes bail 12 and base portion 140. The bail assembly 110 is identical to the bail assembly 10 described above, except that the base portion 140 includes a platform 144 that defines a plurality of fastener receiving openings 160, 162. Each of the plurality of fastener receiving openings 160,162 receives a fastener 164, 166. Fasteners 164,166 help secure bail assembly 110 to structure 100. The fasteners may be, for example, fasteners or bolts. It is contemplated that the bail assembly may be secured to the structure in other ways than as depicted in fig. 9A, 9B.
