Abstract

Abstract A connector arrangement for the detachable fastening of airplane wings to the fuselages of model airplanes. The arrangement utilizes generally tongue and groove-like T-shaped connector elements, which are connected to each other within the fuselage, or to a constructional element located therein, by a rubber band under pretensioning. These tongue and groove-like connector elements are adapted to be swivelled or rotated in their extended positions, and may then come into contact with an intermediate member or the outer surface of the fuselage, and are maintained in their rotated positions. In this position, the tongue and groove-like connector element, upon attachment of the airplane wing, may be positioned in a cutout formed in the end surface of the wing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 124 words
In a connector arrangement for the detachable fastening of airplane wings to the fuselages of model airplanes, including sleeves in said fuselages, and pins in said airplane wings adapted to be located in said sleeves for attaching said wings to said fuselages, the improvement comprising tongue and groove connector elements for pressing said wings against said fuselage; a rubber band imparting a tensile force to said connector elements, each said connector element being adapted to be pulled out and rotated into a second position in which said connector element is insertable into a complementary-shaped cut-out formed in the end surface of the airplane wing proximate thereto, and rotatable into a first position in which said airplane wing is maintained in engagement with said fuselage.
Claim 2
Dependent Claim 124 words
In a connector arrangement for the detachable fastening of airplane wings to the fuselages of model airplanes, including sleeves in said fuselages, and pins in said airplane wings adapted to be located in said sleeves for attaching said wings to said fuselages, the improvement comprising tongue and groove connector elements for pressing said wings against said fuselage; a rubber band imparting a tensile force to said connector elements, each said connector element being adapted to be pulled out and rotated into a second position in which said connector element is insertable into a complementary-shaped cut-out formed in the end surface of the airplane wing proximate thereto, and rotatable into a first position in which said airplane wing is maintained in engagement with said fuselage.
Claim 3
Dependent Claim 63 words
A connector arrangement as claimed in claim 1, said connector element being located interiorly of said fuselage in the first position thereof, and being supported against said fuselage in a withdrawn condition from said fuselage in the second position thereof at rotation through an angle of 90°, said connector element, in the first position thereof, being locked against rotation interiorly of said fuselage.
