second pair pin

74,76 each all be housed inside be formed on inverted U-shaped demarcation strip the 62A of limb portion, 62B one of them the

corresponding joint

78,80 of lower end and the outward flange of second flap 60 in the corresponding joint 82,83.Be formed with opening in the demarcation strip between two 62A of limb portion, 6B and central joint 68.

Because closure member 14 may be heavier and be difficult to handle, so first and

second flaps

58,60 are provided with the guiding

elements

84,86 that mutually combines, to guide closure member 14 with respect to the motion of underframe 12 between open position and closing position.First of guiding elements 84 is outstanding from first flap 58, and has first cam face 88.Second guiding elements 86 is outstanding from second flap 60, and has second cam face, 90, the second cam faces 90 with first cam face, 88 contacts on first guiding elements.Can be clear that from Fig. 7 A to 7C, first and second guiding surfaces are curves, and at the raised

ends

92,94 and the narrower neck between

end

92,94 and

respective hinge plate

96,98 that define on these guiding elements towards the guiding elements end.

The operation of this hinge is described to 7C now with reference to Fig. 4 and Fig. 7 A.

Fig. 7 A shows when closure member 14 is in closing position, the relative position of first and

second flaps

58,60, and at this moment, the wheel rim 48 of closure member is aimed at the flange portion 30 of underframe.When hinge is in this situation following time, the end 94 of second guiding elements 86 is placed in the neck area 96 of first guiding elements 84.As shown in FIG., first guiding elements 84 is outstanding by the opening in the separating plate 62, and this opening is limited by the 62A of limb portion, 62B and the central joint 68 of separating plate 62.

Hinge when Fig. 7 B shows closure member 14 and moves to the position that partially opens.In this position, the end 94 on second guiding elements 86 has advanced on the end 96 on first guiding elements 84.As shown, the lower end of demarcation strip 60 has been moved to the left an a small amount of with respect to it in the position shown in Fig. 7 A.Thereby second flap 60 and closure member 14 pivot with respect to demarcation strip 62 down around
