    • The present invention relates to a toy comprising at least two parallel wheels each comprising a hub (14), a rim (16) provided with a tread (18), and a plurality of spokes (20) made of an elastically deformable material. The unit formed by the hub and the spokes is mounted into the rim under compressive stress on the spokes, so as to produce, by buckling effect, a bending of the spokes curving these latter and offsetting axially the plane of the hub with respect to that of the rim. The unit can hence take two stable positions in the direction of bending of the spokes, i.e. an extended position with an enlarged track and a retracted position with a reduced track. It is just needed to apply an external mechanical effort on the rim, in one direction or the other, to reverse the direction of bending of the spokes, and thus to switch from the extended position to the retracted position, or vice versa.
    • 本发明涉及一种玩具,其包括至少两个平行轮,每个轮包括轮毂(14),设置有胎面(18)的轮辋(16)和由弹性变形材料制成的多个轮辐(20)。 由轮毂和轮辐形成的单元在轮辐上的压缩应力下安装在轮辋内,以便通过弯曲效应产生弯曲这些后者的轮辐的弯曲,并相对于该轮毂轴向偏移轮毂的平面。 的边缘。 因此,该单元可以沿着辐条的弯曲方向,即具有放大轨道的延伸位置和具有减小的轨道的缩回位置的两个稳定位置。 只需要在轮辋上沿一个方向或另一个方向施加外部机械力,以反转轮辐的弯曲方向,并且因此从延伸位置转换到缩回位置,反之亦然。

    • An axle extension device for broadening the wheel base of a vehicle includes a circular extender plate having a plurality of bores adapted to receive the mounting studs of a vehicle hub therethrough. Nuts may be threadably attached to ends of respective mounting studs to secure the plate to the vehicle hub. A number of stud bolts equal to the number of mounting studs extend outwardly from the extender plate and may selectably extend through corresponding holes of a hub of a vehicle tire/wheel combination. The wheel may be secured thereto with lug nuts. The stud bolts are configured such that a tire/wheel combination configured for attachment to the vehicle mounting studs is configured for attachment to the extender plate. The extender plate has a thickness such that a tire/wheel combination attached thereto is displaced from the vehicle's wheel hub so the vehicle's wheel base is broadened.
    • 用于拓宽车辆车轮底座的车轴延伸装置包括具有多个孔的圆形延伸板,该多个孔适于容纳通过其中的车辆轮毂的安装柱。 螺母可以螺纹连接到相应的安装螺柱的端部,以将板固定到车辆轮毂。 等于安装螺柱数量的多个双头螺栓从扩展板向外延伸,并且可选择地延伸穿过车辆轮胎/车轮组合的轮毂的相应孔。 轮可以用凸耳螺母固定到其上。 双头螺栓构造成使得构造成用于附接到车辆安装螺柱的轮胎/车轮组合被配置为附接到扩展板。 扩展板具有使得附接到其上的轮胎/轮组合从车辆轮毂移位的厚度,使得车辆的车轮基座变宽。
