Claims8
A foldable stand for supporting an article comprising platform means including longitudinally extending, laterally spaced side members, a scissor mechanism having first and second diagonally intersecting leg means each having upper and lower ends, the upper end of said first leg means being pivotally connected to said platform means, a pair of slidable brackets each mounted on one of said side members and connecting the upper end of said second leg means to said side members for sliding movement therealong, said platform means being movable by said scissor mechanism between a lower folded position and a raised unfolded position, a pair of gas springs each connected between one of said side members and one of said slidable brackets and positioned laterally between said side members substantially within the planar confines of said side members, said gas springs providing a lifting force which assists movement of said platform means from said lower folded position to said raised unfolded position.
A foldable stand for supporting an article comprising platform means including a generally U-shaped frame having longitudinal side members connected at one end by a lateral base member, a scissor mechanism having first and second diagonally intersecting leg means each having upper and lower ends, the upper end of said first leg means being pivotally connected to said platform means, a pair of slidable brackets each having tubular means telescopically slidably mounted on one of said side members and connecting the upper end of said second leg means to said side members for sliding movement therealong, said platform means being movable by said scissor mechanism between a lower folded position and a raised unfolded position, gas spring means connected between said frame and said slidable brackets, said gas spring means providing a lifting force which assists movement of said platform means from said lower folded position to said raised unfolded position.
