  • Patent number: 9939046
    Abstract: A chain catch that is capable of being attached to various bases so as to allow the quick and simple affixation of the chain catch to any vertical chain. The chain catch has an upper body and a lower body. The upper body is designed to trap a vertical chain within its internal design while it remains within its vertical orientation, and the lower body is designed to attach to a load and to the upper body. When the tension is taken off of the chain within the chain catch and the upper body is tilted, the chain may be vertically raised, free from the chain catch or the chain catch and its attached barbell can be vertically raised.

  • Patent number: 9757604
    Abstract: An exercise device having many advantageous features is described, including the ability to provide users with multiple modes of training by transforming the device into different configurations. Users can exercise their cardiovascular endurance by using the device in its jump rope configuration. Users can also engage in muscular resistance training using the same device configured to one of multiple possible resistance training configurations. Resistance training configurations provide a method of suspending users' bodyweight such that they can train their muscular strength capacity by exerting themselves against the force of gravity. Resistance can be selected from nearly zero resistance to a user's full body weight, with the ability to easily adjust between exercises and between users, and the ability to easily transform the device between configurations to provide for versatility and ease-of-use.

  • Patent number: 9282789
    Abstract: A cufflink with a decorative head, an elongate post attached at one end to the head and an elongate toggle member pivotally attached to the opposite end of the elongate post, and a compressible spacer member. The cufflink solves the problem of inadvertent opening (the toggle member being pivoted into colinear alignment with the elongate post) by having the deformable spacer member which prevents the toggle pivotally attached on the elongate post from opening prematurely. The compressible spacer produces resistance to prevent the toggle, when rotated 90 degrees to the elongate post, from opening and it is sized and shaped to eliminate any space between the toggle, in the closed position at 90 degrees and the shirt making it almost impossible to have the toggle open without manually forcing the toggle to open.

A slide has a body and first and second holes passing entirely through. The first hole encompasses the support hoop at a first distinct location and the second hole encompasses the support hoop at a second distinct location. The slide operatively traverses the support hoop and thereby alters a bias of the support hoop from an open orientation suitable to receive or remove animal excrement bags to a more nearly closed orientation suitable to retain animal excrement bags. A coupling engages the support hoop with the carabineer.

  • Patent number: 4809496
    Abstract: A mechanism for joining a chain end to a chain link utilizes a sliding link connected to a first link of the chain. The sliding link can be disengaged only by displacing it onto the straight portion of the first link and moving it forwardly to a second position. For connection, the sliding link is moved about the straight portion to a third position and is then moved upon engagement of a second chain link by an opposite displacement back to the locking position. Thus locking and unlocking is achieved only by two specific movements of the sliding link. Inadvertent unlocking is prevented by the shape and position of the sliding link.

    Abstract: There is disclosed in the specification an improved tire chain including at least one pair of tire gripper portions adapted at one of their ends to exert pressure on the tire at the tread of the tire, and at the other end on their respective sidewall near the rim of the tire. Such tire gripper portions are adapted to grip the tire independently, but by themselves do not have strength to resist the rotational forces of the tire.To add to the traction of the tire, and hold the individual tire gripper portions on the tire during rotation, a pair of connecting chains is employed between the two tire gripper portions. To resist disengagement from the tire during rotation by centrifugal force, a pin portion is provided on the inner end of each gripper portion which is adapted to press into the tire to a predetermined stop so that such pin portion is actually embedded in the sidewall of the tire. It is disclosed that such pin portion could also engage a preformed recess in the sidewall of the tire.

  • Patent number: 4271888
    Abstract: A snow chain assembly having a pair of cross-chains is connected with a wheel assembly by a pair of connecting devices. One connecting device includes a lug mounted to the inside of the wheel and a cooperating socket plate that receives the lug and is secured thereby. The second connecting device includes a T-shaped radial slot and a T-shaped pin connected to the chain. When the pin is inserted in the slot and moved radially outward, the slot prevents disengagement of the pin. Spring biased retaining members may be attached to the wheel as locks to further prevent chain disengagement.
