Abstract: A swivel wheel device (Fig. 1) is disclosed, designed to be mounted underneath a load bearing surface (21). The swivel wheel device (Fig. 1) comprises a substantially horizontal bar (2) adapted to pivotally turn about a vertical axle (20); at least one of a plurality of main wheels (3), provided at the bottom of the horizontal bar (2), so that the vertical axle (20) lies in the plane of rotation of the main wheel (3); and at least one of a plurality of support wheels (5), provided at the top of the horizontal bar (2), the axis of rotation of the at least one of a plurality of support wheels (5) is aligned radially with respect to the axis of rotation of the bar (2). When the swivel wheel device (Fig. 1) is positioned on a surface and moved in a predetermined direction, the load bearing surface (21) is supported by the at least one support wheel (5), and the bar (2) is caused to swivel about the vertical axle (20) and align the at least one of a plurality of main wheels' plane (see 3) of rotation in the predetermined direction, thus facilitating motion of the device (Fig. 1) in any desired horizontal direction.
