Abstract: A load bearing apparatus is configured to simulate a payload. The load bearing apparatus includes a load member configured to simulate the mass of a payload, a frame having frame members, a plurality of retainers configured to support the load member, and first and second outer guides coupled to the load member. The plurality of retainers includes a first retainer positioned at a first height and configured to support the load member at the first height, and a second retainer positioned at a second height different from the first height and configured to support the load member at the second height. The first and second outer guides are coupled to the load member and are configured to receive therebetween at least one lifting member of a lifting device. By using load members of different weights and positioning them at varying heights, different centers of gravity can be achieved.

Abstract: A tie retaining device according to the present invention includes a fastener part having a front side and a back side, the front side supporting a pair of opposed, laterally projecting barbs, and the back side including an eyelet. The retaining device also includes a retainer clip for connecting to either a button on a shirt or the centerline of the shirt to secure the retainer clip to the shirt, and a prong for removably coupling with the eyelet of the fastener part. The fastener part barbs are inserted into the rear, folded back flaps of a tie body to attach the fastener part to the tie. The narrow tie tail is then inserted through an elongated opening in the fastener part. The eyelet on the back side of the fastener part is then threaded onto the prong of the retainer clip. In an alternate embodiment, the retainer clip is replaced by a retainer chain which is attached at one end to the center of a rod, and at the other end to a clasp.
