Abstract:
A ball rebound device for ball games comprising: a frame structure, a sheet being detachably attached to the front of the frame structure and adjusting means connected to the frame structure, the adjusting means being able to move part of the frame structure, whereby the tension of the sheet can increase or decrease. By stretching the sheet, it is possible to increase the rebound force of the sheet by ball impact. Similarly, the rebound force can be decreased when the sheet is slackened.
