A conductor system includes a music stand and at least one support rack. The music stand and the support rack can be used independently, but can provide additional stability when coupled to each other. The podium and the rack can be positioned to accommodate the preferences of a user, including by height, radial, lateral, and pitch/tilt adjustments. The support rack is adapted to receive any number of user instruments, such as, for example, a laptop or an electronic keyboard. The podium and the rack can be transported without being lifted completely off the support surface.

An acoustic door assembly generally comprises a door, a frame and a hinge. The door of the assembly is an insulated, acoustic door having a predetermined length. The frame of the assembly is positioned proximate the door and is joined thereto by the hinge. The hinge is a continuous, cam hinge having a length that is substantially equivalent to the predetermined length of the door and is secured along the length of the door.

A mobile teaching station includes a mobile teaching surface designed to support a plurality of teaching props during instruction of students. A mobile storage facility for storing the teaching props is disposed proximate the mobile teaching surface and operably coupled thereto. The mobile teaching station further includes devices for readily transporting the mobile teaching surface to a desired teaching site. A method of facilitating mobile teaching of students includes the steps of (a) providing a mobile teaching surface designed to support a plurality of teaching props during instruction of students, (b) providing a mobile storage facility for storing the teaching props proximate the mobile teaching surface and operably coupled thereto, and (c) providing devices for readily transporting the mobile teaching surface to a desired teaching site.

The choral riser of the present invention is adapted to be supported on a stage surface. The choral riser has a base that presents two spaced apart base supports, each of the base support having a first and a second spaced apart pivot point. A first step member has a step pivot point and a base pivot point that is operably pivotally coupled at the base pivot point to the base at the base first pivot point and has at least one step presented thereon. A second step member has a step pivot point and a link pivot point that is operably pivotally coupled at the step pivot point to the first step member at the first step member step pivot point and has a plurality of steps presented thereon. A bar link member is operably pivotally coupled at a first end pivot point to the second step member bar link pivot point. The bar link member is operably pivotally coupled at a second end pivot point to the base second pivot point. The first and second step members are pivotable between a stowed configuration, with at least one of the steps of the first step member facing at least one of the steps of the second step member, and an operational configuration in which the steps of the first and second step members present an ascending succession of steps. The steps are readily reversible to change the stage presentation form.

A rod end has a split clamp housing which supports a bearing for transferring motion or loading forces from an actuator to another part to be loaded. An adjustable stop for the clamp is used to adjust the backlash of the bearing used with the rod end to a desired level without causing distortion. A spherical washer set is used for transferring loads between the two clamp portions. The housing for the bearing is clamped against the spherical washer set at a preselected loading so that the bearing is able to rotate and swivel as needed, but backlash is removed.
