Abstract: A wheelchair exercise device comprising two assemblies, each assembly comprises: a seat plate; a longish pipe element; and a wide belt. The seat plate is L-shaped and made of hard material, the longish pipe element is flexible and has padding on its top side, the longish pipe element mounted onto ferrule or hole integrated approximately in the middle of the vertical edge of the L-shaped seat plate, the first end of the wide belt is attached to the longish pipe element and adjustable upwards, downwards and around the pipe of the longish pipe element, and the second end of the wide belt has hook and loop fastener. The two assemblies are adapted to be fastened onto each other by the hook and loop fasteners, and the assemblies are designed so that the combined measurement of both the width and length of the seat plates is smaller than the measurement of a wheelchair seat, thereby allowing the width and vertical adjustment of the location of the seat plates on the wheelchair seat.

Abstract: The invention comprises an exercise device for back and abdominal muscles to be fastened onto a wheelchair.

Abstract: The object of the invention is a mooring compensator not needing any rope threading; instead, even after the boat is moored, it can effortlessly be fastened onto any rope (6) with a simple loop (7, 8). The special characteristic of the mooring compensator is that, when pulled, the openings (9, 9A) at the end elements (2, 2A) of the mooring compensator close, thereby efficiently preventing the loop (7, 8) in the boat rope (6) from sliding out of the opening (9, 9A) and from opening.

Abstract: The invention consist of a tarp or cover (1) which edge area is equipped with loops (2,3) intended for a rope or plank (7) to hold the tarp (1) tight over the covered object.

Abstract: The invention consists of a chair back support, which consists of at least two flexible elongated supports (2,2a) on both sides of the seat (1), which supports (2, 2a) are connected with support belts (3, 3a and 4, 4a), all supporting a person's back and making gymnastic movements possible both for the back and stomach while sitting on the chair.

Abstract: The invention is an apparatus for exercising deep abdominal and back muscles, consisting of a minimum of at least two flexible vertical frames at a distance from each other for a person to fit in, whose other ends are anchored onto a base. The frames are connected to one another with an up/down adjustable abdominal/back support.

Abstract: The invention is an apparatus for exercising deep abdominal and back muscles, consisting of a minimum of at least two flexible vertical frames (2) at a distance from each other for a person to fit in, whose other ends are anchored (7) onto a base (5). The frames (2) are connected to one another with an up/down adjustable (9) abdominal/back support (4).

Abstract: The object of the invention is a rake, which can be said to be a combination of the rigid garden rake and the flexible leaf rake. This result can be achieved by giving the garden rake a flexible frame (A), which, down to its prong part (B;D), can be divided in two or more parts (G;H;I).

Abstract: An apparatus for exercising the back and abdominal muscles, including an elongated beam and at least two spaced devices for transferring forces between the beam and its user. The preferred embodiment includes a lower crossbar for transmitting force from the beam to the user's shins or calves and a pad for transmitting force from the beam to the user's back or stomach. It also includes an upper crossbar and shoulder straps for transmitting force from the user's shoulders to the beam. An alternate embodiment includes an arcuate, laminated beam member in which the flexibility in bending is adjustable. It also includes a lower crossbar attachable to the user's ankles by means of a pair of ankle straps and an upper crossbar attachable to the shoulders with a pair of shoulder straps. When the alternate embodiment is in use, the central portion of the beam, which is preferably padded, contacts the user's back or stomach, transmitting force thereto.
