An assembly for use with a weight rack includes a mounting rail for mounting to the weight rack, including a plurality of rail sections extending laterally and spaced along the length of the mounting rail to define slots therebetween. The accessory includes a mounting portion for removably mounting to the mounting rail and a functional portion connected to the mounting portion for use in a weightlifting exercise. The mounting portion includes a fixed portion and a moveable portion that is moveable with respect to the fixed portion between a locked position, where the fixed portion and the moveable portion engage the mounting rail, and a release position, where the accessory can be removed from the rail. The mounting portion also includes a peg received in one of the slots of the mounting rail and a locking mechanism that moves the moveable portion between the locked position and the release position.

A connector for connecting a first part to a second part, the connector including a tongue element with substantially parallel first and second surfaces, with a perimeter of the tongue element increasing from the first surface to the wider second surface. The connector includes at least one cylindrical element extending out from the first surface in a substantially perpendicular direction. The first part includes a groove and the second part includes at least one hole. Each cylindrical element of the connector is pressed into a respective hole of the second part to form a friction fit connection and the tongue element of the connector is inserted into the groove of the first part at a wider opening of the groove and then slid along the groove towards a more narrow opening so that the tongue element becomes wedged into an end of the groove at the more narrow opening.

A delivery vehicle has separate compartments with a common sidewall. Doors that are interchangeable between the compartments close the compartments. A latching assembly between the doors and sidewall limits movement of the sidewall when only one of the doors is closed. The compartments are combined into a single compartment by moving the sidewall when the doors are open. A hinge assembly connects the doors. A contact and wiper assembly between the doors carries power and commands for the hinge assembly.

A method of making a cabinet carcass using a pair of connectable box carcass framework members for the fabrication of non-panel constructed furniture carcasses. It simplifies the construction of a furniture carcass and uses but a minimum of tools and skill to produce a dimensionally square, precisely sized, box that accepts an abundance of aesthetic and functional options. The assembly is based on a pair of mechanical fastener connectable vertical and horizontal members that have connectable zipper channels, linear rabbets for the retention of side panels, screw busses, and open channels with series of spaced orifices therein for the passage of mechanical connectors.
