Abstract: A hip loading board for exercise includes linear-motion elements. The linear-motion elements include linear-motion bearing motion elements to provide free motion in one direction. The hip loading board can include one or more interchangeable resistance elements that provide a force to return a moving plate to a start position.

Abstract: A swing motion trainer used to simulate one or more sport swing movements includes a rod portion comprising a shaft with a grip. The swing motion trainer includes a resistance portion comprising an interchangeable mechanism at a distal end of the rod portion, the resistance portion includes an interchangeable mechanism at the distal end of the rod portion, wherein the interchangeable mechanism is configured to attach a removable resistance element to the distal end of the rod portion. The removable resistance element that is attachable to the distal end of the rod portion via the interchangeable mechanism. The removable resistance element provides a resistance to a swinging motion of the swing motion trainer.

Abstract: A hip loading board for exercise includes linear-motion elements. The linear-motion elements include linear-motion bearing motion elements (e.g. a linear slide). One or more linear-motion elements of the hip loading board can be designed to provide free motion in one direction. Example linear slides (compound slides, dovetail slides, rack slides, ball bearing-based slides, magnetic slides, etc.) can be non-motorized dovetail slides, ball bearing slides, roller slides, etc. that provide a low-friction linear movement. The hip loading board can include one or more interchangeable resistance elements that provide a force to return a moving plate to a start position. The interchangeable resistance elements may also provide a linear resistance (e.g. any material which creates a constant resistance or tension, variable resistance or tension, etc.).

Abstract: A tag attacher for inserting tag fasteners into articles such as clothing or the like has a very simplified fastener advancing and positioning mechanism consisting entirely of a gear, a stopper adapted to permit unidirectional gear rotation and a one-piece gear advancer. The gear advancer which is operably connected to a main actuating lever of the tag attacher is V-shaped and includes a pin at the base of the V for making a hinged connection to the main lever, a pawl extending from the pin to the gear and a resilient arm which biases the pawl against the gear. The main lever also operates a sliding lever supporting a driving rod adapted for back and forth reciprocating movement. The driving rod pushes a lateral bar of the tag fasteners through a needle of the tag attacher into the article to be tagged.
