Abstract
A jumping board which is particularly well-suited to provide a surface on which a person may jump rope. The board comprises a resiliently deformable member of foam material having a pair of oppositely disposed substantially planar surfaces and a peripheral edge surface joining the planar surfaces about the periphery of the deformable member. First and second planar sheet members are disposed in surface contact and adhered with the planar surfaces of the deformable member. The jumping board additionally includes a resiliently deformable peripheral edge member for the periphery of the deformable member. The edge member has first and second spaced end edge portions and an intermediate body portion. The first and second end edge portions are joined to the peripheral edges of the first and second planar sheet members, respectively, about the entire periphery of the deformable member, and the intermediate body portion is spaced from the peripheral edge surface of the deformable member to define a hollow area therebetween. The intermediate body portion is sufficiently rigid to prevent curling of the deformable member at the peripheral edge surface so as to maintain a substantially planar …
