Abstract: A convention box is folded from a single flat sheet of cardboard, corrugated board or other similar rigid material, to form a disposable yet durable attache case that can be handed out to attendees at a convention or meeting. Side panel members attached to a back panel fold over tabs that are associated with top and bottom panels to lock the box into a rigid, rectangular shape, and also provide rigidity to the side panels. The handles for the convention box are formed as handle halves each formed in a respective front and rear top panel. A slot can be provided in the rear panel for insertion of literature without having to open the box.

Abstract: A training device for competitive swimmers in the form of a drag producing belt adapted to be worn over the swimmer's regular suit or trunks. The drag producing belt adds weight and increases the resistance (drag) to the swimmer's movement through the water and thus helps in the development of the swimming muscles. The increased drag is caused by normally open ended pockets that are secured to the belt in such a manner that they act as scoops as the swimmer moves through the water. Water entering the pockets is impeded in flowing through them whereby the drag is created. The pockets are located on the belt so that the drag is distributed evenly on the swimmer with no imbalance tending to cause the swimmer to roll or dip.

Abstract: A training device for competitive swimmers in the form of a drag suit adapted to be worn over the swimmer's regular suit. The drag suit adds weight and increases the resistance (drag) to the swimmer's movement through the water and thus helps in the development of the swimming muscles. The increased drag is caused by a plurality of pockets on the front and back of the suit which pockets open in the direction of the swimmer's movement through the water. Water entering the pockets is impeded in flowing through them whereby the drag is created. The pockets are located on the suit in such a manner that the drag is distributed evenly on the swimmer with no imbalance tending to cause the swimmer to roll or dip.
