  • Each stand-off plate comprises a hole, in which a pin 34, 34' is engaged.
  • the pins 34, 34' are part on the lock mechanism provided on the battery box 16, and the engagement of said pins with the holes provided in the stand-off plates 33, 33' on the rails 15, 15' thus locks the battery box against movement on or away from the rails and prevents removal of the box 16.
  • Figure 8 is a closer view showing in more detail the right lock mechanism shown in Figure 7.
  • An identical mirrored structure can be recognized on the left side of Figure 7. It can be seen that a lateral end of the strap 31 of the tension boom 30 is connected to a ring 35, which is preferably made from a non flexible, rigid material, such as metal or hard plastic.
  • the ring 35 engages in a hole at a central end of a pin, the pin being retained in a support comprising a holding element 36 and two screw nuts 37, 38, through which the pin 34 is guided.
  • the holding element is rigidly attached to and stands off from the wall of the battery box 16.
  • the pin 34 is resiliently harboured within a space provided by said nuts 37, 38 and said holding element 36.
  • the pin When a person draws the strap 31, the pin is drawn in a transversal movement towards a slightly more central position with respect to the wheelchair. The lateral end of the pin, which engages the hole in the stand-off plate 33 of the rail 15 is removed from said hole. However, at some point, the pin is blocked within the elements 36-38 in which it is harboured, so that the pin cannot be completely removed by exerting a drawing force on the strap 31. The pin 34 thus contributes together with the support elements 36-38 to a secure connection between the strap 31 and the battery box 16.
  • a resilient element for example a spring, which is not visible in the figures, is also harboured within the support elements 36-38 and is placed so as to provide a resilient pressure on the pin in an axially outward direction, that is towards the locked position, in which the pin 34 is engaged in the hole of the stand-off plates 33.
  • This resilient construction prevents the lock mechanism from being unlocked unintentionally, in that the pin 34 does not spontaneously disengage from the hole in the stand-off plates 33.
  • Figure 8 shows the lock mechanism in the wheelchair of the invention in a locked position.
  • a traction is exerted on the tension boom 30, said traction being passed via the ring 35 on the pin 34 as shown in Figure 9.
  • the traction is exerted against the force of the resilient means (not shown) keeping the pin in the engagement with the corresponding hole in the stand-off plate 33 of the rail 15 and thus results in an unlocking of the lock mechanism.
  • the traction on strap 31 by drawing in a rearward direction also results in the corresponding pin 34' on the left side of the wheelchair (not shown) being disengaged and thereby the left lock mechanism being unlocked.
  • Figures 11 through 13 show the same situation as Figures 8 through 10, respectively, but from a different, lateral perspective view.
  • part of the carrier 26 has already been passed over the rear end of the rails.
  • further traction exerted on the strap in the direction indicated by the arrow will lead to a removal of the battery box 16 from the rails 15, 15'.
  • Figure 14 shows the battery box 16 in a perspective view of its left, rear and top side.
  • the box 16 comprises a basic container 41 on which a lid 42 is placed and detachably fixed by way of four clip mechanisms 43, 43', 44, 44', two on each side, with the clips on the right side not being visible in this view.
  • the four clips on the lid can be actuated by hand for lifting the lid and removing the battery inside the battery box, as will be described further below.
  • Figure 14 shows the hand-actuated device (the tension flange 30) comprising the strap 31 that can be grasped by a person when the box 16 is hung up on the rails on the chassis of the wheelchair, as has been described above.
  • the right and left lock mechanisms 32 and 32' as well as the respective pins 34, 34' can also be seen to be part of the box.
  • the right and left carriers 26, 26' of the box which lie on the rails and thus carry the box 16 in a position of use can be seen to be relatively large and comprising a plurality of reinforcing structures 49 for assuring that the battery is safely harboured in the box when the latter is suspended on the rails.
  • Each right and left carriers 26, 26' also comprise an opening 58, 58' forming a grip, respectively, which allows to a person to conveniently lift the battery box 16 by gripping the container 41 at the carriers 26, 26'.
  • Figure 15 is an exploded view of the battery box 16 with the lid 42 being lifted and showing more details of some inner elements of the box such as the battery 45 itself as well as the male connector 50.
  • the battery 45 can be conveniently removed from the container when the lid is lifted following opening the four clips 43, 43', 44, 44', preferably by hand.
  • An advantage of the present invention is that the wheelchair can at least partly be demounted by hand, without the need of any special or ordinary tool. From the exploded view of Figure 15, it can be seen that a connector 50 is provided, which, when the lid 42 is on the container, is retained in an open area HOa and HOb provided in the lid 42 and the container 41.
  • This open area is situated in a central position at the interface of the container 41 and the lid 42 (the open area 110b in the lid 42 is not visible in Figure 15 but its position is indicated by reference numeral 110b).
