Definitions

  • the present invention relates to the field of wheelchairs and in particular to a wheelchair chassis. More particularly, the present invention relates to a wheelchair chassis that can be stored in a space-saving manner.
  • Wheelchairs, and in particular motorized wheelchairs are relatively encumbering devices. This characteristics stems from the fact that motorized wheelchairs, for example, are composed of a multitude of different parts that are arranged in a relatively narrow space in the chassis of the wheelchair.
  • GB 2448110 discloses a foldable electric wheelchair.
  • the problem of the high space requirements of wheelchairs is also important during transport of wheelchairs, for example to a maintenance workshop or due to travel of a wheelchair user. It is thus also an objective to provide a way to transport wheelchair or wheelchair chassis in a space-saving manner.
  • the present invention also addresses the problem of providing a wheelchair chassis that can be partially dismounted and stored in a space-efficient way.
  • the present invention further addresses the problem of a wheelchair or a wheelchair chassis that is transformable to a position of storage or transport, which covers less surface than when the wheelchair or wheelchair chassis is in a position of use.
  • the present invention provides a wheelchair chassis comprising a pair of anti-tip wheels, wherein said wheelchair chassis has an horizontal position of use and a vertical position of storage, wherein each anti-tip wheel is provided on a curved support arm movably mounted with respect to said wheelchair chassis, and wherein, in said position of storage said curved support arm is in a position that is moved with respect to the position of use, in order to allow the wheelchair to be positioned in said vertical position.
  • said curved support arm In said position of storage said curved support arm may be in a position that is rotated with respect to the position of use by an angle of about 90 to 270°.
  • the wheelchair chassis may lie on motorized drive wheels and on said anti-tip wheels.
  • Said anti-tip wheels may be provided on a rotable support arm, wherein in said position of storage the wheelchair chassis may lie on motorized drive wheels and on said anti-tip wheels.
  • the curved support arm In a position of use, the curved support arm may be blocked against any rotation.
  • Said curved support arm may be associated with a lock mechanism preventing rotation of said support arm in the position of use and/or in the position of storage.
  • Said lock mechanism may be actuated and unlocked by hand.
  • Said lock mechanism may comprise at least one pin, which, in a position of use and/or in a position of storage blocks any relative movement between said support arm and a holding structure provided on the chassis of the wheelchair.
  • Said pin may engage said support arm and said holding structure in a position of use and/or in a position of storage and may be disengaged from one or both of said support arm and/or said holding structure by hand and/or without the need of a special tool.
  • a disengagement of said pin from the support arm and/or said holding structure may allow the rotation of the support arm.
  • One selected from said holding structure and the support arm may comprise a hollow cylindrical section and the respective other of said holding structure and the support arm may comprise a cylindrical or tubular section, wherein tubular section engages in said hollow cylindrical section.
  • a hand-actuatable lock mechanism may prevent rotation of said tubular section in said hollow cylindrical section.
  • Said support arm or said holding structure may comprise a limiting structure limiting transversal movement of the support arm with respect to said holding structure in at least one direction when the said lock mechanism is unlocked.
  • Said support arm and said holding structure may both comprise an opening, wherein, in a position of use and/or in a position of storage, when relative movement between said support arm and said holding structure is blocked, the openings are aligned and said pin crosses said openings and thereby blocks said relative movement.
  • the wheelchair chassis of the present invention may be the wheelchair chassis of a motorized wheelchair, wherein in said position of storage batteries are removed from the wheelchair chassis.
  • the present invention also relates to a wheelchair comprising the chassis of the present invention.
  • Figure 1 shows an embodiment of the wheelchair chassis 1 of the present invention. If compared to a completely assembled wheelchair, the chassis shown in Figures 1 differs in that the seat, arm and legrests of the complete wheelchair are removed.
  • the perspective rear view of Figure 1 shows a pair of right and left motor wheels 6, 6', right and left rear anti-tip wheels 8, 8' and a right front castor wheel 7 (the left front castor wheel 7' 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.
  • a right motor 10 is visible, and together with a left motor (not visible), the motors are provided in order to propel the left and right motorized wheels 6, 6', respectively.
  • the castor wheels 7, 7' and the motorized wheels 6, 6' are fixed to the chassis.
  • the anti-tip wheels 8,8' are provided at the rear end of the left and right curved support arms 9, 9', said support arms being attached to swing arms being part of the chassis.
  • the chassis 1 comprises a main, U-shaped frame element 11, the open end of the U being oriented towards the front.
  • a horizontal frame element 12 is provided in a front area of the chassis.
  • a pair of battery boxes 13, 14 is loaded on the chassis 1 at the rear of the wheelchair.
  • the present invention concerns more specifically the arrangement of wheels other than the main drive or motorized wheels.
  • the present invention is applicable to wheels such as idler wheels or anti-tip wheels of a wheelchair.
  • Anti-tip wheels are typically provided as pairs of smaller wheels if compared to motorized or drive wheels. These pairs of smaller wheels are typically arranged towards the front or the rear end of a wheelchair and have, as a main purpose, the maintenance of the stability and/or maneuverability of a wheelchair. These smaller wheels are thus often provided at the rear-to-front extremities of a wheelchair and therefore determine the overall length and encumbrance of a wheelchair chassis.
  • the present invention provides a possibility of change the orientation and/or position of such smaller wheels in order to allow a less encumbering, space-saving position of storage and transport for the wheelchair.
  • situations and directions of elements of the wheelchair chassis of the present invention are determined by the perspective of a user seated in the completely assembled wheelchair. Accordingly, the left side of the wheelchair chassis 1 corresponds to the left side of Figure 1 .
  • the situations or directions “up” or “top” and “down” or “bottom”, “rear” or “back” and “front”, “behind” and “in front”, “distal” and “proximal”, “lateral” and “central” follow the same rule.
  • the principle of the present invention is illustrated at the example of the anti-tip wheels 8, 8' of the wheelchair chassis 1 shown in Figures 1 and 2 .
  • Anti-tip wheels generally are not in touch with the ground on which a complete wheelchair moves, but may come in contact when a wheelchair is tipping over or runs on an obstacle. In these situations, the anti-tip wheels are provided to prevent falling over of the wheelchair.
  • the left and right anti-tip wheels 8, 8' are mounted at the rear distal end of dedicated, left and right support arms 9, 9', which in turn are mounted at their front end to the chassis.
  • FIG 2 is the same wheelchair chassis as shown in Figure 1 , with the battery boxes 13, 14 being removed, normally loaded on the rear end of the chassis 1 ( Figure 1 ).
  • the embodiment of the wheelchair chassis shown in the figures of this specification is intended for storage or transport with the battery boxes being removed beforehand.
  • the present invention also encompasses the possibility that the battery boxes stay on the wheelchair chassis when the wheelchair chassis is prepared or placed in a position for storage, as detailed further below.
  • each anti-tip wheel support arm 9, 9' comprises a nearly horizontal, front profile section 20, a bent section 22 and a rear, nearly vertical anti-tip wheel carrying section 21.
  • the angle ⁇ that the front profile section 20 deviates from horizontal is actually important for enabling storage of the wheelchair chassis in a space-saving manner.
  • FIG. 3b In particular in Figures 3b and in the perspective, closer view of Figure 4 , of the right anti-tip wheel, it can be seen that the rear portion 20 of the support arm 9 is guided in a tubular element 25, which thus functions as a holding structure having a hollow cylindrical configuration.
  • the holding structure 25 is rigidly connected to the chassis 1, for example by welding or screwing, and more particularly to a lateral frame bar 30, which carries, on its lower side, the motor of the motorized wheel.
  • the right motorized wheel is removed in Figures 3b and 4 for the reason of clarity.
  • the support arm 9 carries, at its lower, rear end, a fork 23, in which the anti-tip wheel 8 is turnably mounted.
  • Figure 5 shows the support arm 9 of the right anti-tip wheel 8 being removed from the tubular element 25 and therefore also from the wheelchair chassis 1.
  • a sleeve 28 provided on the front, substantially horizontal portion 20 of the support arm 9 can well be seen in Figure 5 .
  • This sleeve abuts against the rear end of the tubular element 25 when the support arm 9 is inserted, as can be seen in Figures 3a, 3b and 4.
  • Figure 5 further shows a clasp 32 comprising two pins 31.
  • the clasp 32 is situated inside the front profile section 20 of the support arm 9.
  • the pins 31 pass through holes 33 in the front profile section 20 and also through similar holes 29 in the tubular element 25 ( Figures 3a, 3b , 4 ).
  • said clasp 32 thus achieves a rigid but detachable connection between the support arm 9 and the tubular element 25 and thus links the support arm 9 to the chassis 1.
  • this mechanism functions as a lock mechanism and is capable of blocking any rotational movement of the support arm 9 in said tubular element 25 and also any transversal movement of the front profile section 20 of the support arm 9 in the tubular holding element.
  • the pins 31 ( Figure 5 ) are accessible from the outside in a position of use of the wheelchair chassis, and even of the completely assembled wheelchair, as they pass through the hole 33 in the support arm 9 and also through hole 29 in the holding structure 25.
  • a wheelchair user or any other person can push said pins back when grasping the holding structure 25, thereby disengaging the pins from the hole 29 of the holding structure 25.
  • the support arm 9 becomes unblocked from the holding structure and is free to move transversally within said holding structure 25 towards the rear.
  • the arrow in Figure 6 illustrates how the support arm 9 is transversally drawn in the rear direction while being guided in the tubular holding structure 25.
  • the extent of movement can be recognized at the position of the retainer sleeve 28, which, in the positions of use shown in Figures 3a, 3b and 4 , abuts against the holding structure 25.
  • the retainer sleeve 28 is situated at a distance of several centimeters away from the rear end of the tube of the holding structure 25.
  • the support arm can, however, be blocked in the upward position of the anti-tip wheels by pushing the support arm transversally back into the holding structure 25, as is illustrated by the arrow in Figures 9a and 9b .
  • the support arm 9 is pushed until the sleeve 28 on said support arm abuts again on the rear end of the tube of the holding structure 25. If, in this position, the support arm is rotated until an exact vertical position of the rear section 21 is obtained, the pins 31 ( Figure 5 ) in the support arm 9 will again pass through the holes 29 in the holding structure 25 and thereby block further rotational and transversal movement of the support arm 9.
  • the clasp 32 shown in Figure 5 is such that two pins 31 are diametrically opposed with respect to each other (180°).
  • the rear section 20 of the support arm 9 actually comprises two holes 33, a second hole being provided diametrically opposed (not visible in Figure 5 ).
  • the holding structure 25 comprises two holes 29, of which the second one is diametrically opposed and cannot be seen in the figures. This arrangement is such that when the support arm is rotated by exactly 180°, the pins 31 can again be moved into the holes 33 and 29. Then the pins block the support arm in a position that is rotated by 180° with respect to the previously blocked position.
  • FIGs 10 and 11 show a space-saving position of the wheelchair chassis shown in the previous figures. This position is useful for storage of the wheelchair chassis when not needed, for example in a maintenance workshop, or for transport. This position is obtained by tilting the front of the wheelchair chassis up-wards and rotating the wheelchair chassis around the main motorized wheels, until the longitudinal rear-to-front dimension of the wheelchair chassis is oriented vertically. The wheelchair chassis is then stabilized and supported on the main wheels 6, 6' and on the anti-tip wheels 8, 8'. As was mentioned above, the anti-tip wheels usually do not touch the ground when the assembled wheelchair is in a horizontal position of use. However, in the vertical position of storage of the wheelchair chassis shown in Figures 10 and 11 , the anti-tip wheels touch the ground and support the wheelchair chassis in this position.
  • the front section 20 of the support arm 9 has a close to horizontal position, but is slightly skewed upwards towards the rear, thereby enclosing an angle ⁇ with respect to horizontal.
  • the careful adjustment of this angle is important not only in order to assure the proper functioning of the anti-tip function of the anti-tip wheels in the assembled wheelchair, but also for assuring that the rear section 21 of the anti-tip wheels assumes a substantially vertical or close to vertical configuration following the up-ward pivoting of the support arm as shown in Figures 7 , 8, 9a, 9b .
  • the angle ⁇ is thus related to the angle between the front and rear sections 20 and 21 of the curved support arm 9. More specifically, angle ⁇ corresponds to the angle enclosed between said front and rear sections 20 and 21 of the curved support arm 9 minus 90°.
  • the length of the various elements of the support arm 9 is relevant as well as the position of attachment of the arm on the chassis with respect to the ground. The skilled person will be able to vary these elements when necessary or desirable for other reasons.
  • the axis of pivoting of the support arm 9 in the holding structure 25 lies in a plane that is vertically extending in the longitudinal, rear to front direction of the wheelchair chassis. Deviations of this situation of the axis are possible.
  • the support arms could be oriented slightly outwardly, in which case the axis of pivoting would be provided at an angle ⁇ (not shown) of about 0-70° from a vertical rear-to front longitudinal plane.
  • the anti-tip wheels are provided in a rear position of the wheelchair chassis.
  • the anti-tip wheels are constructed with the anti-tip wheels provided in the front of the wheelchair.
  • the present invention analogously also applies to wheelchairs with front anti-tip wheels.
  • the rear portion 20 of the support arms 9, 9' is not guided in a tubular element 25, but is mounted in articulation onto the chassis (or onto another element fixed to the chassis or to a swing arm being part of the chassis, such as for example the tube 25), for example through a universal or cardan joint, so as to be able to be pivoted to serve as support when the wheelchair chassis is in its vertical position of storage, so that the wheelchair chassis can be stabilised and supported on the main wheels 6, 6' and on the anti-tip wheels 8, 8'.
