Abstract
The invention relates to a light vehicle such as a golf caddie which includes a body and at least two wheels that are respectively connected to the body by first and second axles. The axles can be pivoted in a first position in which they are tilted against the body and in a second position in which they extend away from the body, where the second position is defined as the driving position of the vehicle. At least one spring acts on the body and on the axles, maintaining the driving position of the axles only by the elastic force thereof, without additional transversal supports and bracing.
Claims13
A small vehicle with a body and at least two wheels each connected to the body via first and second stub axles attached to the body via a hinge, wherein the stub axles are pivotable in a first position in which they are folded up against the body and a second position in which the stub axles extend out from the body in a traveling position wherein at least one spring is provided which engages on one side at the body and on the other at the stub axles via said hinge and by its spring force alone holds the traveling position of the stub axles without additional radial reinforcements and stays;
- and wherein at least either the body or one or both stub axles have, at their sections adjoining the hinge, a hollow section in which the spring is housed.
A small vehicle with a body and at least two wheels each connected to the body via first and second stub axles attached to the body via a hinge, wherein the stub axles are pivotable in a first position in which they are folded up against the body and a second position in which the stub axles extend out from the body in a traveling position, wherein at least one spring is provided which engages on one side at the body and on the other at the stub axles via said hinge and by its spring force alone holds the traveling position of the stub axles without additional radial reinforcements and stays, wherein the spring is a gas-pressure spring which can be locked at least in the traveling position of the stub axles.
A small vehicle with a body and at least two wheels each connected to the body via first and second stub axles attached to the body via a hinge, wherein the stub axles are pivotable in a first position in which they are folded up against the body and a second position in which the stub axles extend out from the body in a traveling position wherein at least one spring is provided which engages on one side at the body and on the other at the stub axles via said hinge and by its spring force alone holds the traveling position of the stub axles without additional radial reinforcements and stays;
- wherein the body consists of two substantially parallel outer pipes rigidly connected to each other, each of which is connected in their lower area via said hinge to one of the stub axles;
- and wherein there is arranged between the two outer pipes of the body a third pipe which serves as a guide pipe for a steering rod housed therein.
A small vehicle with a body and at least two wheels each connected to the body via first and second stub axles attached to the body via a hinge, wherein the stub axles are pivotable in a first position in which they are folded up against the body and a second position in which the stub axles extend out from the body in a traveling position wherein at least one spring is provided which engages on one side at the body and on the other at the stub axles via said hinge and by its spring force alone holds the traveling position of the stub axles without additional radial reinforcements and stays;
- wherein each of the stub axles is pretensioned by an additional spring in the direction of the folded-in position;
- wherein the additional spring acts on the hinge via a Bowden wire and a guide roll.
