- the hand-actuated device 30 is provided in the form of a tension boom or tension flange 30 that basically comprises a flexible strap or band 31, which can be grasped by a person from behind the wheelchair, when the wheelchair is in a position of use.
- the lock mechanisms 32, 32' are unlocked and the battery box 16 can be removed at the rear end of the wheelchair by sliding on the rails 15, 15' and finally sliding off the rails.
- right and left stand-off plates 33, 33' are attached, for example welded, at the rear end of the rails 15, 15'.
- 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 .
- 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'.
- FIG 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 110a and 110b 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).
- the open areas 110a, 110b are bordered by a doubled wall 48a and 48b on the container and the lid, respectively.
- a sleeve 111 provided on the connector fits within the double walls 48a and 48b so that when the lid 42 is mounted the connector is stabilized in the open areas 110a, 110b of the container and the lid.
- the male connector 50 in the rear box 16 is adapted to fit a female connector 120 of the front battery box 17, which can be seen in Figure 2 and also in Figure 17 below.
- open areas 112a and 112b are also provided on the rear side of the rear battery box.
- the open area 112 formed by open areas 112a and 112b on the rear side of the container 41 and the lid 42, respectively, is closed by a place-holder 100, which can also be seen in Figures 1, 2 and 7 .
- the place-holder 100 actually comprises a small lumen (not shown) in which small spare parts 101 can be placed.
- there as two spare fuses 101 placed in the place-holder disk 100 there as two spare fuses 101 placed in the place-holder disk 100.
- Figures 16 and 17 show an assembled and an exploded view, respectively, of the front box 17.
- the front box 17 is largely identical in shape and size as the rear box 16, and in particular the container 41 as such and the lid 42 of the front box 17 is substantially identical to the corresponding structure, which is why identical reference numerals are used.
- This also applies to the open areas 112a, 112b, 110a, 110b in the front box 17, whereas the suspension carriers 27, 27' provided on the right and left side, respectively, of the container 41, were given separate reference numerals already previously.
- the front battery box 17 does not comprise a lock mechanism.
- the tension boom 130 of the front box 17 thus comprises a band 131, which is directly attached to the container 41 and does not comprise a resilient locking pin as described with reference to Figures 7-14 above.
- a further difference between the front and the rear battery box is that the front battery box 17 harbors a female connector 120, which is designed to engage with the male connector 50 of the rear battery box 16. In this way, the batteries 45 of the front and rear battery boxes 16, 17 are connected with each other.
- a front connector 60 of the front battery box 17 is designed to engage with a female socket 70 visible in Figures 3-6 .

Figure 1 shows an embodiment of thewheelchair 1 of the present invention with the seat, arm and legrests of the wheelchair being removed for the reasons of clarity. Any one selected from the seat, the armrests and or the legrests may be demountable and remountable. The perspective rear view ofFigure 1 shows a pair of right andleft motor wheels 6, 6', right and left rearanti-tip wheels 8, 8' and a right front castor wheel 7 (the left front castor wheel not being visible in this view). The anti-tip wheels are connected at the end of right and left curved support arms 9, 9', respectively. Aright motor 10 is visible, and together with a left motor 10' (not visible), the motors are provided in order to propel the right and left motorizedwheels 6, 6', respectively. Thecastor wheels 7, 7' and themotorized wheels 6, 6' are fixed to a chassis or frame 5. Theanti-tip wheels 8, 8' are provided at the rear end of the right and left curved support arms 9, 9', said support arms being attached to swing arms being part of the chassis 5. The chassis 5 comprises a main,U-shaped frame element 11, the open end of the U being oriented towards the front. Ahorizontal frame element 12 is provided in a front area of the chassis 5. - The
wheelchair 1 shown inFigure 1 comprises two demountable boxes, arear box 16 and afront box 17, in which batteries are accommodated. On therear box 16, a hand-actuateddevice 30 can be seen. For the purpose of clarity it is noted that the term "box" and "container are generally regarded as equivalent, which applies in particular to the appended claims. For the purpose of the present disclosure, however, the term box is generally used for referring to the entire element encasing the battery, the box thus comprising a lid and a container as such, which can be closed by the lid. The term "container" then generally refers to the lower, open element of the battery box. The term "hand-accessible" refers to the fact that this structure can be reached and gripped by the hand of a person, for example a wheelchair user, a service person or any assisting person. The hand-actuateddevice 30 is provided in the form of a strap or band, and when a person draws on the strap, a locking mechanism opens and thebattery box 16 can be removed from the chassis. - The batteries provided in the
containers -
Figure 2 shows the same wheelchair asFigure 1 , but with thebattery boxes wheelchair 1. With the batteries being removed, the left motor 10' can be seen, and rails 15, 15' can be seen better. As will be described in more detail below, thebattery boxes Figure 1 , and also in the position of use of the wheelchair. InFigure 2 , a strap orgripper 130 provided on thefront battery box 17 can be seen. While thestrap 130 on the front battery box also provides a grip for removing thebattery box 17 from the rails, there is no lock mechanism provided associated with thefront battery box 17. Of course, it would be possible to provide such a lock mechanism also on thefront box 17. The position of thebattery boxes rear battery box 16 is removed first, followed by the removal of thefront battery box 17. The latter can be accessed only after removal of the former, and is otherwise sandwiched and thus blocked within the chassis and therear battery box 16. Therear battery box 16, in turn, is stabilized or blocked against any uncontrolled movement by thefront battery box 17 and a lock mechanism provided between therear box 16 and the chassis, as will be detailed further below. Therails 15, 15' connected to the chassis 5 prevent lateral displacement of thebattery boxes Figure 1 ). -
Figure 3 shows an enlarged view of the wheelchair with the batteries being removed as inFigure 2 . The battery boxes are no longer shown inFigure 3 . -
Figure 4 shows thebattery boxes rail construction 20 comprising right and leftrails 15, 15' being removed from the chassis of the wheelchair, the battery boxes and the rail construction being aligned for the purpose of illustration. Therail construction 20 comprises right and leftconnection plates 21, 21' attached to said right and leftrails 15, 15' at about halfway of the longitudinal extension of said rails. Theconnection plates 21, 21' comprise openings for attaching the rail construction on the chassis, for example by way of screws or bolts. Both rails 15, 15' are connected to each other by way of a fronttransversal connecting structure 22, which, together with saidrails 15, 15', forms an U-shaped structure, with the open end of the U oriented towards the rear end of the wheelchair. In a central position, said connecting structure comprises anelectric socket 70, which is designed to engage with anelectric connector 60 provided on thefront battery box 17. A similarelectric connector 50 is provided on therear battery box 16, which engages with a corresponding female part on the front battery box, not visible inFigure 4 . From thesocket 70, cables are provided, not shown, which supply electric energy from thesocket 70 tomotors 10 and 10' (Figures 1 and 2 ) and to a central data processing unit or a computer (not shown). As can also be seen inFigure 4 , eachbattery box lateral carriers rails 15, 15' and thus provide the guiding of thebattery boxes rails 15, 15'. The carryingstructures -
Figure 5 shows the same elements asFigure 4 , with thefront battery box 17 being situated on therails 15, 15', and the rear battery box closely behind the rails. -
Figure 6 , finally, shows thebattery boxes rails 15, 15'.Figures 4 through 6 together thus illustrate the way of movement that thebattery boxes rails 15, 15' in the wheelchair of the present invention. Inversely, when regarded in the orderFigure 6 ,5 and 4 , these figures illustrate the removal of thebattery boxes -
Figure 7 is a closer view to the rear end of therear battery box 16 when placed on therails 15, 15' of the wheelchair of the invention. The hand-actuateddevice 30 and the associatedlock mechanisms 32, 32' are provided on right and left sides of thebattery box 16. The hand-actuateddevice 30 is provided in the form of a tension boom ortension flange 30 that basically comprises a flexible strap orband 31, which can be grasped by a person from behind the wheelchair, when the wheelchair is in a position of use. When drawing thetension boom 30 towards the rear, thelock mechanisms 32, 32' are unlocked and thebattery box 16 can be removed at the rear end of the wheelchair by sliding on therails 15, 15' and finally sliding off the rails. As can already be recognized inFigure 7 , right and left stand-offplates 33, 33' are attached, for example welded, at the rear end of therails 15, 15'. Each stand-off plate comprises a hole, in which apin 34, 34' is engaged. Thepins 34, 34' are part on the lock mechanism provided on thebattery box 16, and the engagement of said pins with the holes provided in the stand-offplates 33, 33' on therails 15, 15' thus locks the battery box against movement on or away from the rails and prevents removal of thebox 16. -
Figure 8 is a closer view showing in more detail the right lock mechanism shown inFigure 7 . An identical mirrored structure can be recognized on the left side ofFigure 7 . It can be seen that a lateral end of thestrap 31 of thetension boom 30 is connected to aring 35, which is preferably made from a non flexible, rigid material, such as metal or hard plastic. Thering 35 engages in a hole at a central end of a pin, the pin being retained in a support comprising a holdingelement 36 and twoscrew nuts pin 34 is guided. The holding element is rigidly attached to and stands off from the wall of thebattery box 16. Thepin 34 is resiliently harboured within a space provided by saidnuts element 36. When a person draws thestrap 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 therail 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 thestrap 31. Thepin 34 thus contributes together with the support elements 36-38 to a secure connection between thestrap 31 and thebattery box 16. However, 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 thepin 34 is engaged in the hole of the stand-offplates 33. This resilient construction prevents the lock mechanism from being unlocked unintentionally, in that thepin 34 does not spontaneously disengage from the hole in the stand-offplates 33. -
Figure 8 shows the lock mechanism in the wheelchair of the invention in a locked position. When a traction is exerted on thetension boom 30, said traction being passed via thering 35 on thepin 34 as shown inFigure 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 therail 15 and thus results in an unlocking of the lock mechanism. Although this cannot been seen inFigure 9 , the skilled person will understand that the traction onstrap 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. Further traction on thestrap 31 results in a movement of thebattery box 16 on and along therails 15, 15' towards the rear, as is illustrated inFigure 10 . InFigure 10 , thebattery box 16 can be seen to be still hung up on therail 15 by way of thecarrier 26 of thebattery box 16. Further traction in the rearward direction as indicated by the arrow inFigure 13 will result in removal of thebattery box 16 from the rails and thereby also from the chassis of the wheelchair. -
Figures 11 through 13 show the same situation asFigures 8 through 10 , respectively, but from a different, lateral perspective view. InFigure 13 , part of thecarrier 26 has already been passed over the rear end of the rails. As in described with respect toFigure 10 above, further traction exerted on the strap in the direction indicated by the arrow will lead to a removal of thebattery box 16 from therails 15, 15'. -
Figure 14 shows thebattery box 16 in a perspective view of its left, rear and top side. Thebox 16 comprises abasic container 41 on which alid 42 is placed and detachably fixed by way of fourclip mechanisms -
Figure 14 shows the hand-actuated device (the tension flange 30) comprising thestrap 31 that can be grasped by a person when thebox 16 is hung up on the rails on the chassis of the wheelchair, as has been described above. The right andleft lock mechanisms 32 and 32' as well as therespective pins 34, 34' can also be seen to be part of the box. Similarly, the right and leftcarriers 26, 26' of the box, which lie on the rails and thus carry thebox 16 in a position of use can be seen to be relatively large and comprising a plurality of reinforcingstructures 49 for assuring that the battery is safely harboured in the box when the latter is suspended on the rails. Each right and leftcarriers 26, 26' also comprise anopening 58, 58' forming a grip, respectively, which allows to a person to conveniently lift thebattery box 16 by gripping thecontainer 41 at thecarriers 26, 26'. -
Figure 15 is an exploded view of thebattery box 16 with thelid 42 being lifted and showing more details of some inner elements of the box such as thebattery 45 itself as well as themale connector 50. Thebattery 45 can be conveniently removed from the container when the lid is lifted following opening the fourclips Figure 15 , it can be seen that aconnector 50 is provided, which, when thelid 42 is on the container, is retained in an open area 110a and 110b provided in thelid 42 and thecontainer 41. This open area is situated in a central position at the interface of thecontainer 41 and the lid 42 (the open area 110b in thelid 42 is not visible inFigure 15 but its position is indicated by reference numeral 110b). The open areas 110a, 110b are bordered by a doubledwall 48a and 48b on the container and the lid, respectively. Asleeve 111 provided on the connector fits within thedouble walls 48a and 48b so that when thelid 42 is mounted the connector is stabilized in the open areas 110a, 110b of the container and the lid. Themale connector 50 in therear box 16 is adapted to fit afemale connector 120 of thefront battery box 17, which can be seen inFigure 2 and also inFigure 17 below. It is worthwhile noting thatopen areas Figures 14 and15 , when therear battery box 16 is mounted and thelid 42 closed, the open area 112 formed byopen areas container 41 and thelid 42, respectively, is closed by a place-holder 100, which can also be seen inFigures 1, 2 and7 . The place-holder 100 actually comprises a small lumen (not shown) in which smallspare parts 101 can be placed. In the embodiment shown inFigure 15 , there as twospare fuses 101 placed in the place-holder disk 100. -
Figures 16 and 17 show an assembled and an exploded view, respectively, of thefront box 17. Thefront box 17 is largely identical in shape and size as therear box 16, and in particular thecontainer 41 as such and thelid 42 of thefront box 17 is substantially identical to the corresponding structure, which is why identical reference numerals are used. This also applies to theopen areas front box 17, whereas thesuspension carriers 27, 27' provided on the right and left side, respectively, of thecontainer 41, were given separate reference numerals already previously. - It is noted though that the
front battery box 17 does not comprise a lock mechanism. Thetension boom 130 of thefront box 17 thus comprises aband 131, which is directly attached to thecontainer 41 and does not comprise a resilient locking pin as described with reference toFigures 7-14 above. Once therear battery box 16 being unlocked and removed from therails 15, 15', thefront battery box 17 can be grasped attension boom 130 and the front battery can be drawn along therails 15, 15' towards the read end of the wheelchair and removed from the chassis as the rear battery box. Since, in a position of use, the front battery box is sufficiently blocked between therails 15, 15', further elements of the chassis and, towards the rear, by the rear battery box, a separate lock mechanism for the front battery box is advantageously not necessary any more. - A further difference between the front and the rear battery box is that the
front battery box 17 harbors afemale connector 120, which is designed to engage with themale connector 50 of therear battery box 16. In this way, thebatteries 45 of the front andrear battery boxes front connector 60 of thefront battery box 17 is designed to engage with afemale socket 70 visible inFigures 3-6 . - The
batteries 45 visible in the exploded views ofFigures 15 and17 , provided in the rear andfront battery boxes negative poles 46, 46', which are connected by electric connections such as isolated cables (not shown) to theconnectors socket 70 provided on the chassis (Figs. 3-7 ).
