发明名称 Torsion device
摘要 A torsion device for facilitating opening and closing a gate attached to a support. The device broadly includes a first section, a second section, and a coupling section. The second section includes an angled portion and a contact portion. The angled portion is operable to be substantially inserted into the gate such that the contact portion generally abuts an interior surface of the gate when the gate is substantially opened. The coupling section couples the first section and the second section such that opening of the gate causes a torsional force to be applied by the device to facilitate opening and closing of the gate. The abutting of the contact portion improves functionality and reduces damage to the gate caused by the torsional force.
