Definitions
- the invention is based on a wheelchair according to the type of the main claim, which is not only about improving comfort for physically handicapped people, but also about expanding the range of use or application of such wheelchairs.
- the wheelchair according to the invention with the features of the main claim also has the advantage that it can be used as a commercial work chair, for example in the office.
- a wheelchair with storage space arranged under the seat on the chassis is known per se (EP PS 0 127 511).
- the disadvantage of this wheelchair is that there is access to the storage space from the front or the back of the wheelchair, wheelchair sides to which the physically disabled person normally has no access.
- Wheelchairs the two wheels of which are hub-free and are connected to the chassis via support bearings, are also known (DE OS 38 19 925, EP OS O 430 794).
- the use of hub-free wheels is primarily intended to reduce the risk of injury to the physically disabled person and there is more empty space under the seat to accommodate simple transport aids such as trays.
- the crossbars form a "cage" with the support elements.
- this type of frame formation achieves high internal stability.
- at least two crossbars of this type are present, with steering support rollers, seat and backrest or the support device being attachable to these crossbars.
- the steering support rollers or the footrests can also be attached directly to other parts of the chassis.
- the power transmission from these crossbars to the support elements is particularly easy to intercept.
- a support ring can preferably serve as the support element, which is supported on the respective impeller via radial bearings.
- the crossbars can also be connected to one another, for example when arranging the seat or the backrest, two such crossbars being usable for this purpose.
- the storage device has a pull-out device which can be pulled out through the open wheel segment and which has an ironing device for receiving objects, such as commercially available hanging files or the like. has or a basket or a drawer for the transport of other goods.
- a pull-out device which can be pulled out through the open wheel segment and which has an ironing device for receiving objects, such as commercially available hanging files or the like. has or a basket or a drawer for the transport of other goods.
- the seat is arranged with its center approximately above the imaginary connecting axis of rotation of the barrel axis, whereby the center of gravity of a seated person is just behind this axis in the direction of travel and being on the back of the At least one steering and support roller is articulated on the chassis of the wheelchair.
- the access to the pulled-out support device is considerably simplified and the position of the person in relation to the wheels for driving them is also improved, since access to the gripping rings is cheaper.
- the castors can turn more easily when turning. Apart from the fact that the overall length of the wheelchair can be shortened considerably by the arrangement according to the invention, its maneuverability is also increased.
- This advantage exists both in terms of the effort required by the person to steer the wheelchair and the short, maintainable turning radii due to the short center distance. These advantages are particularly important when used in the office, for example when starting up at a desk.
- the main advantage of using it in the office is that the disabled person can cope with almost the same space requirement as a non-disabled person. The person does not need a separate job.
- At least one steering and support roller is articulated on the front of the wheelchair.
- two steering and support rollers are arranged on the rear of the wheelchair, while such a role on the front is sufficient so that the wheels create a five-point support on the floor, similar to what is required for office chairs that are provided with roles.
- a wheelchair is known in which the center of gravity is shifted to the rear and in which a steering and support roller is provided at the front and rear (DE OS 27 51 079).
- this known wheelchair does not have hub-free wheels, so that this crucial feature is not present.
- a rotating roller bearing serves as the support bearing, the non-rotating inner ring of which forms part of the chassis.
- the roles can be kept relatively far apart, for example, by cages in order to get by with a minimum of roles.
- the inclination of the seat and / or backrest is adjustable. This is especially true if the wheelchair is to be suitable for use in an office, whereby the seat shells that are customary for office chairs can be used, in particular with an anti-slip device for negative seating angles.
- the seat surface can be equipped with a multi-chamber air cushion, which on the one hand makes long-term sitting more bearable.
- a controllable connection through which an air cushion wedge lying between the thighs of the person can be automatically inflated to prevent slipping when the patient is tilted forward (negative sitting position).
- a valve arranged in the adjusting device for the seat inclined position can serve for the control. With a negative seat inclination, an air cushion part blows between the Thighs that stop slipping forward. The wedge is not present at the positive seat angle. It is therefore possible to adopt different sitting postures. The footrest is then sprung to follow the movement of the seat.
- the wheelchair can be folded up, which is particularly useful when using crossbars and, in particular, is easy to implement due to the fact that there is a relatively large free space between the wheels.
- Fig. 2 is a plan view of the wheelchair with partial cross section as the first variant with a bracket and
- Fig. 3 shows the wheelchair in a perspective view, with the second variant with a drawer. Description of the embodiment
- the wheelchair according to the invention is equipped with a chassis which has a frame which has two support rings 1 arranged largely parallel to one another, which are rigidly connected to one another via four cross bars 2.
- a chassis which has a frame which has two support rings 1 arranged largely parallel to one another, which are rigidly connected to one another via four cross bars 2.
- hub-free impellers 3 are mounted on the support rings 1 via radial bearings (not shown).
- Grip rings 4 are attached to each of the running wheels 3, by means of which the person 5, only indicated by dashed lines, can operate the running wheels.
- the person 5 sits on a seat 6 which is adjustable in its inclined position and which is arranged via an adjusting device 7 which in turn rests on brackets 8 which are each fastened to two crossbars 2.
- a slip part 17 is provided on the front part of the seat 6.
- an arm 9 is also adjustably attached, on which a likewise adjustable backrest 11 is arranged.
- two steering and support rollers 13 are articulated via cantilever arms 12, while in the same way only one steering and support roller 13 is articulated on the front cross bar 2.
- the respective roller can yield upwards or backwards or forwards, for which it is connected to the respective rod by spring means (not shown).
- a footrest 14 is also attached to the front lower crossbar 2.
- a storage device 16 is provided which can be pulled out laterally through the hubless impellers via a telescopic system in such a way that it is easily accessible from above.
