Workpiece support, useful for processing machine, comprises support pins, selection bars, actuating bars, and protective cover, where support pin is displaceable to actuation bar between operating position and unlocked position

The workpiece support comprises support pins (10), selection bars (12a, 12b, 12c), actuation bars (14a, 14ab, 14c), and a protective cover. Each of the support pins is displaceable: to the actuation bar between an operating position (20) and an unlocked position by a distance change of the selection bar; and between the unlocked position and a storage position (24) by the distance change of different relative movements of the actuation bar to the selection bar. Each selection bar comprises a parallelly aligned guide rail, and U-shaped recesses. The workpiece support comprises support pins (10), selection bars (12a, 12b, 12c), actuation bars (14a, 14ab, 14c), and a protective cover. Each of the support pins is displaceable: to the actuation bar between an operating position (20) and an unlocked position by a distance change of the selection bar; and between the unlocked position and a storage position (24) by the distance change of different relative movements of the actuation bar to the selection bar. Each selection bar comprises a parallelly aligned guide rail, and U-shaped recesses. The actuating bar is disposed in a plane of the guide rails and perpendicular to the guide rails. The support pins are disposed in the storage position in the guide rails. The selection bars are arranged above the actuation bar and the support pins in the operating position. Each support pin comprises a foot with an abutment surface. A receptacle of the selection bar engages on an alignment surface of the foot. The actuation bar engages the support pin in the unlocked position so that the abutment surface of the foot is released against the alignment surface. Each actuation bar comprises: retaining elements, which, in the unlocked position, engage on the support pin for a relative movement of the support pin during the relative movement of the actuation bar; and recesses. A pivot pin of the support pin is arranged in each recess of the selection bar. The recesses of the selection bar and the actuation bar, in the unlocked position, engage with each other such that a bearing for the pivot pin of the support pin is formed. A selection of the selection bars is displaceable by a first distance change from the operating position into the unlocking position and/or by a second distance change from the unlocking position into the operating position irrespective of the position in which the individual actuation bars are located. The selection of the actuation bars is displaceable by a
