Abstract
Abstract A ball-game device comprising a baffle wall arranged on a transportable stand is characterized by the fact that the baffle wall has a front surface designed in the shape of a spherical indentation, and there is provided a frame. The frame surrounds the baffle wall and is supported on the stand. The baffle wall is, in turn, supported on the frame by means of at least one flexible fastening element.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
81 words
A ball-game device, comprising: a stand; a frame supported on said stand; and a baffle wall made of non-yielding material for reflecting a ball surrounded by said frame and supported thereon by at least one flexible fastening element, said baffle wall having a concave front surface in the form of a spherical indentation, said fastening element permitting yielding of said baffle wall with respect to said frame upon impact by said ball and then returning said baffle to its resting position.
Claim 2
Dependent Claim
81 words
A ball-game device, comprising: a stand; a frame supported on said stand; and a baffle wall made of non-yielding material for reflecting a ball surrounded by said frame and supported thereon by at least one flexible fastening element, said baffle wall having a concave front surface in the form of a spherical indentation, said fastening element permitting yielding of said baffle wall with respect to said frame upon impact by said ball and then returning said baffle to its resting position.
Claim 3
Dependent Claim
35 words
The device of claim 1, wherein a plurality of said fastening elements are provided along said frame in an evenly spaced-apart manner, by means of which elements said baffle wall is suspended in said frame.
Claim 4
Dependent Claim
12 words
The device of claim 2, wherein said fastening elements are elastically resilient.
Claim 5
Dependent Claim
16 words
