Abstract:
1. A cattle grid comprising a set of bars having a first configuration in which the upper portions of the bars are spaced apart to define gaps therebetween, and a second configuration in which the gaps between the upper portions of the bars are substantially reduced to avow passage of animals across the bars, wherein the set of bars comprises: a first group of fixed bars that are spaced apart with gaps therebetween; and a second group of bars that are moveable between a lower position and an upper position to change the set of bars between the first and second configurations, wherein the first configuration of the set of bars comprises the second group of bars being in the lower position such that the upper portions of each of the bars of the second group are lower than the upper portions of the bars of the first group, whereby gaps are defined between the bars of the first group, and wherein the second configuration comprises the second group of bars being in the upper position such that the second group of bars intermeshes with the first group of bars so that the bars of the second group occupy the gaps between the bars of the first group, so that the upper portions of the bars of the first and second group of bars cooperate to provide a substantially stationary surface that allows the passage of animals while in the second configuration.
