초록 ▼

A closure panel arrangement is provided in which a closure panel 6 can only be retained when appropriately aligned with engagement between clasp hooks 8 and pins 9 is achieved along with association between latch hooks 10 and pins 11. If there is not appropriate association and alignment then a bias 12, 22, 32, 42 creates an outward bias force upon the closure panel 6 whereby the panel 6 will continue to fall out. In such circumstances, the panel 6 cannot remain in position due to simply key fit interference/friction association of sufficient strength for non-operational conditions but which will fail during operation due to vibration or stresses.

I claim: 1. A closure panel arrangement for fairings or cowlings or airframes, the arrangement comprising a closure panel secured in use across an opening from hinge edges located on opposite sides of said opening, the closure panel initially retained about each hinge edge upon a mounting edge whereby that panel may pivot about each hinge edge until located and then secured by securing means across the opening, the arrangement characterised in that the closure panel is associated with a radial outward bias member, arranged to bias the panel in an opposite direction to its closure, to ensure, if the panel is not secured properly, the panel will fall out of position, said radial outward bias member being located substantially intermediate said hinge edges. 2. An arrangement as claimed in claim 1 wherein, the hinge edge and the mounting edge reciprocally co-operate with respective hook clasp and pin means associated in order to allow pivot about the hinge edge. 3. An arrangement as claimed in claim 1 wherein the closure panel is secured in place by latch means. 4. An arrangement as claimed in claim 1 wherein the bias is centrally located between the hinge edge and mounting edge. 5. An arrangement as claimed in claim 1 wherein the bias projects from a base structure. 6. A closure panel arrangement for fairings or cowlings or airframes, the arrangement comprising a closure panel secured in use across an opening from a pair of spaced apart hinge edges, the closure panel initially retained about said hinge edges upon mounting edges whereby that panel may pivot about said hinge edges until located and then secured by securing means across the opening gap, the arrangement characterised in that the closure panel is associated with a radial outward bias, arranged to bias the panel in an opposite direction to its closure, to ensure if the panel is not secured properly the panel will fall out of position wherein the bias comprises a torsion spring located at an intermediate position between said hinge edges. 7. An arrangement as claimed in claim 6 wherein the torsion spring is in contact with the closure panel through a roller. 8. An arrangement as claimed in claim 6 wherein the torsion spring will be displaced through an angle of 90째 as it presents bias to the closure panel upon pivot about the hinge edge of the opening or gap. 9. An arrangement as claimed in claim 1 wherein the bias may be provided by a foam or rubber insert or an inflated bag or a hydraulic compression spring or a mechanical compression spring. 10. An arrangement as claimed in claim 1 wherein the bias is secured to the closure panel and/or other parts to prevent complete fall away of the closure panel when incorrectly aligned. 11. An arrangement as claimed in claim 1 wherein the bias acts against a reinforced portion of the closure panel. 12. An arrangement as claimed in claim 1 wherein the bias is removable after correct alignment is achieved with that bias present.
