Abstract

452,324. Retractable undercarriages for aircraft. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S. 1. A. M., 1, Route des Alpes, Fribourg, Switzerland. April 16, 1935, No. 11736. Convention date, Jan. 12. [Class 4] In a retractable landing gear for aeroplanes of the kind in which a wheel or the like is carried by a leg constituted by two hinged members, one of which acts as a pneumatic or oleo-pneumatic shock-absorber, the movement of the leg is guided during retraction and extension by a directing bar of constant length hinged at one end on a fixed point on the aeroplane and at the other on the non-mobile (cylinder) member of the shock absorber. In one form, Figs. 1 and 2, a wheel 1 is carried by a leg 2, pivotally mounted on the aircraft structure at 3 and constituted by two elements hinged together at 6, the lower element consisting of a shock absorbing strut comprising a cylinder c and piston p. A directing bar 9 is pivoted at 8 to the aircraft structure and at 7 to the cylinder c of the shock absorber. Retraction and extension are effected by means of a jack 10 pivoted to the aircraft structure at 11 and to cylinder c at 12. In another form, Fig. 2, retraction and extension ace effected by a jack 13 pivoted at one end on a fixed point 14 and acting at the other on a hinge 15 provided in an auxiliary leg 16-16. According to the Specification as open to inspection under Sect. 91, the wheel carrying member 2 might be constituted by any device of elastic character or otherwise. This subject-matter does not appear in the Specification as accepted.
