Thebottom attachment plate 34 is attached to the floor of thestorage volume 182.Fig. 2 further denotes a secondhorizontal direction 62, perpendicular to the firsthorizontal direction 60. -
Fig. 3 schematically represents anactuator 78 and a block linkage mechanism 36 (covered by thecover 186 inFig. 2 ). Theactuator 78 comprises anactuator pin 74. Theactuator pin 74 is linearly movable in amovement direction 76. - The
block linkage mechanism 36 of this example comprises afirst link member 46, asecond link member 48, athird link member 50 and afourth link member 52. Theblock linkage mechanism 36 further comprises aplate member 42 having aslot 44. - The
first link member 46 is pivotally connected to theactuator pin 74 at apivot 54. Thefirst link member 46 is pivotally connected to thesecond link member 48 at apivot 56. Thesecond link member 48 is pivotally connected to a fixedpivot 84, i.e. fixed relative to thedoor 12. Thethird link member 50 is pivotally connected to thesecond link member 48 at apivot 64. - The
third link member 50 is pivotally connected to thesecond link member 48 at apivot 64. Thethird link member 50 comprises aslot 188. Thefourth link member 52 comprises apivot pin 68 guided in theslot 188 of thethird link member 50. - The locking

The lockingplate rod 40 is pivotally mounted to arotatable member 86. Therotatable member 86 is rotatable about apivot 88. The movement of the lockingplate rod 40 causes therotatable member 86 to rotate inrotational direction 92. The rotation of therotatable member 86 pushes alink member 94 viapivot 90. The movement of thelink member 94 pushes a lockingplate 38 via apivot 102 to move indirection 96. The locking plate is arranged under the bottom attachment plate. - The locking
rod 10 comprises awaist 100 and alocking pin 98. At thewaist 100, the lockingrod 10 may for example have a diameter of 12 mm. Thewaist 100 resists breaking of the lockingrod 10 by shear forces. - In the illustrated position in
Fig. 4 , the lockingplate 38 engages thewaist 100 such that the lockingrod 10 is blocked. When theactuator pin 74 moves from the starting position to a first position, the lockingrod 10 is locked by the lockingplate 38. -
Fig. 5 schematically illustrates a top view of the lockingplate 38. The lockingplate 38 comprises an aperture structure having a larger throughhole 106 joined to a smaller throughhole 104. InFig. 4 , the smaller throughhole 104 is engaged. When theactuator pin 74 has moved to the first position, the larger throughhole 106 is aligned with the lockingrod 10. -
Figs. 6 and 7 schematically represent side views of a lockingstructure 108. The lockingstructure 108 is attached to theplate member 30. InFig. 6 , anupper locking pin 112 of the lockingrod 10 is blocked by a lip of the lockingstructure 108. When theactuator pin 74 moves from the first position to the second position, the lockingrod 10 moves from the position inFig. 6 to the position inFig. 7 . If the lockingrod 10 is forcibly moved by a thief, there is a chance that the lockingrod 10 is moved too far up such that thelocking pin 112 is blocked by arecess 110 of the lockingstructure 108. However, when theactuator pin 74 is in the second position, the lockingpin 112 is aligned with the opening of the lockingstructure 108 as shown inFig. 7 . -
Fig. 8 schematically represents a side view of thelock opening linkage 82 of thedoor assembly 184. Theactuator pin 74 is in the second position inFig. 8 . Thelock opening linkage 82 comprises afifth link member 114, arocker arm 120, asixth link member 132 and aseventh link member 138. Thefifth link member 114 is pivotally coupled to therocker arm 120 at apivot 124. Therocker arm 120 is pivotally coupled to thesixth link member 132 at apivot 126. Therocker arm 120 pivots about apivot 122. Thesixth link member 132 is coupled to theseventh arm 138 at apivot 128. Theseventh link member 138 is pivotally coupled to thedoor 12 atpivot 130. Theseventh link member 138 is pivotally coupled to alatch 144 of thelock 16. Thelatch 144 is pivotally coupled to thelock case 16. - A
slot 148 is provided in theactuator pin 74. Apin 116 of thefifth link member 114 is engaged in theslot 148. As can be seen inFig. 8 , when theactuator pin 74 has moved to the second position, thepin 116 has reached the end of theslot 148. - When the
actuator pin 74 moves from the illustrated second position to a third position, thefifth link member 114 moves in themovement direction 74, therocker arm 120 rotates inrotational direction 118, thesixth link member 132 moves in themovement direction 134, theseventh link member 138 rotates inrotational direction 136 aboutpivot 130 and thelatch 144 is rotated in therotational direction 140 from the illustrated closed position to an open position. In this manner, thelock 16 is unlocked. -
Fig. 9 schematically represents a top view of thedoor opening linkage 80. Thedoor opening linkage 80 comprises aneighth link member 154, aninth link member 156 and atenth link member 166. As can be seen inFig. 9 , thehinge 22 comprises aneleventh link member 168 and atwelfth link member 174. Theeleventh link member 168 is pivotally coupled to thechassi 178 of thevehicle 18 at apivot 180. - By moving the
actuator pin 74 from the third position illustrated inFig. 9 to a fourth position, theeighth link member 154 is moved inmovement direction 74. Theeighth link member 154 is pivotally coupled to theninth link member 156 atpivot 162 and pushes theninth link member 156 to pivot about apivot 158 fixed relative to thedoor 12 inrotational direction 160. Theninth link member 156 is pivotally coupled to thetenth link member 166 atpivot 164. When theninth link member 156 is rotated inrotational direction 160, thetenth link member 166 moves and pushes theeleventh link member 168 viapivot 170. Theeleventh link member 168 is thereby rotated (counterclockwise) inFig. 9 to push thetwelfth link member 174. Thetwelfth link member 174 is connected to theeleventh link member 168 at pivot y2. Thetwelfth link member 174 is also connected to apivot 176 fixedly attached to thedoor 12. Thus, when thetwelfth link member 174 is pushed by theeleventh link member 168, thedoor 12 opens. - An emergency opening device may be provided on the inside of the
door 12 to prevent a person to get stuck in thestorage volume 182. A biometric validation may be made before the operator can command the opening sequence of theactuator 78. - While the present disclosure has been described with reference to exemplary embodiments, it will be appreciated that the present invention is not limited to what has been described above. For example, it will be appreciated that the dimensions of the parts may be varied as needed. Accordingly, it is intended that the present invention may be limited only by the scope of the claims appended hereto.
