Abstract
A fence that bounds the outfield of a game played with bat and ball comprises a plurality of mesh panels suspended from a plurality of support posts, with foul posts at either end. The fence can be readily assembled and disassembled. The support posts' anchors can be covered when the fence is disassembled, so that the field is usable for other sports. The function of the fence is twofold: (1) to minimize injury to a player who runs into the fence and (2) to confine such a player within the field of play should the player impact the fence.
Claims20
A fence that confines a softball or baseball outfield, said fence comprising:
- a continuous plurality of flexible, resilient mesh panels joined together in an arc, said plurality of mesh panels being bounded by a pair of foul poles marking the horizontal playing portion of said softball or baseball outfield;
- a plurality of fixed support posts supported from beneath a ground surface in an arc that is offset from the arc defined by the mesh panels and is outside the confines of said outfield, said outfield being defined by the mesh panels, and each fixed support post being angled inwards toward the confines of the outfield;
- said mesh panels having reinforced tensioned upper and lower edges, the reinforced tensioned upper edge being suspended and maintained in position from above by tensioned cables extending diagonally upward and outward from the mesh panels at the confines of the outfield toward respective support posts outside the confines of the outfield, forming an elastically supported arced mesh and cable system, and said mesh panels being attached at the reinforced tensioned lower edge to the plurality of support posts sufficiently close to the ground surface to prevent a baseball or softball from rolling between the lower edge and the ground surface, each mesh panel defining a respective plane which is angularly displaced from a respective defined plane of an adjacent mesh panel by an outward component of the tension supplied by the tensioned cables from the plurality of fixed support posts, and said mesh panels being effective for confining within said outfield a player of said game who runs into said fence, causing a nondestructive deflection of the mesh and cable system, substantially without movement of the fixed support posts, thereby minimizing any injury to said player from impacting said fence.
A sports field fence for confining a softball or baseball sports field having an outfield, comprising:
- a plurality of support posts fixed in position, disposed in an arc outside of the outfield, supported from beneath a ground surface and being inwardly angled at an upper portion;
- a continuous series of flexible, resilient mesh panels defining an arced outer edge of the outfield within and offset from the arc formed by the plurality of support posts, the resilient mesh panels being elastically suspended inside of the arc formed by the plurality of support posts by tensioning cables, a cable tensioned lower edge of the resilient mesh panels being held in fixed position with respect to the ground surface by a downward tension to thereby prevent a ball from rolling between the lower edge and the ground surface, and a cable tensioned upper reinforced edge being elastically suspended above the ground surface at spaced positions from the plurality of support posts by cables which extend diagonally outward and upward from the resilient mesh panels to the inwardly angled upper portion of respective ones of the plurality of support posts, each resilient mesh panel defining a respective plane, wherein a respective defined plane formed by a respective resilient mesh panel is angularly displaced from a respective defined plane of an adjacent mesh panel by a divergent outward component of the tension supplied by the tensioned cables from the plurality of support posts, forming a compliant mesh and cable tensioned system effective for constraining a sports player who runs into a respective mesh panel within the sports field, to prevent injury from impact against the support posts, via a nondestructive deflection of the mesh and cable system.
A sports field fence for confining a sports field, comprising:
- a plurality of support posts each having a fixed position in a ground surface and having an upward and inward extending portion with respect to the sports field, the plurality of support posts being respectively disposed in an arc;
- a series of flexible, resilient mesh panels having upper and lower cables at each of respective upper and lower edges, wherein adjacent mesh panels transmit forces through the respective upper and lower cables, the upper cables being periodically elastically supported by diagonal cables extending upward and divergently outward toward the upward and inward extending portions of the plurality of support posts disposed in the arc, such that the mesh panels are maintained in a deflectable position spaced inside of and offset from the arc defined by the plurality of support posts so as to assume a configuration corresponding to the arc;
- wherein the series of flexible, resilient mesh panels are provided substantially without interruption along the length of the fence;
- wherein the lower cables are held sufficiently close to the ground surface by respective ground links to prevent a sports ball from rolling under the lower edge;
- and
- wherein the series of mesh panels supported by the upper cables, lower cables, diagonal cables and ground links are configured to constrain a sports player within the sports field and are elastically deflectable in response to an impact of the sports player to prevent injury from impact against the support posts.
