Abstract
A device for preventing cart oscillation, wherein the rotation in a horizontal plane of the rear wheel side is controlled by an oscillation controlling member. The rotation in the horizontal place of the rear wheel side is also controlled by a detachable oscillation controlling member having a coupler section for permitting the cart to follow a predetermined course, when a train of a plurality of coupled carts is drawn. As shown in FIG. 5, a device for preventing oscillation for controlling the rotation in a horizontal plane of rear wheels of a cart is detachably fixed to a cart 2 having wheels connected to a wheel support which is rotative in a horizontal plane, in a way to fix the rear wheels by an engagement groove of a slant section 14.
Claims6
A device for preventing oscillation of a cart having a bottom including front and rear wheels operatively connected to wheel supports rotative in a horizontal plane, said device comprising:
- a control means for controlling direction change of the rear wheels which is engageable with the rear wheel supports;
- a pair of side plates connected to said control means which are rotative in a horizontal plane;
- an oscillation control member having a member body for detachably fixing to the cart, said member body having engagement grooves for controlling the direction change of the cart rear wheels by engaging said side plates with said engagement grooves;
- and
- a coupler section for coupling said oscillation control member with another cart.
