Description
- The invention relates to an auxiliary frame for a wheelchair comprising coupling means for coupling the auxiliary frame to the wheelchair, at least one steerable wheel and drive means, wherein the coupling means are formed by a central elongate body provided with a bearing for co-action with the frame of the wheelchair and a clamping bracket pivotally connected to the elongate body and co-acting with the bearing.
- Known from the British patent publication GB-2124985 is a steerable drive unit for coupling to a wheelchair. The drive unit comprises drive and steering means whereby a person sitting in the wheelchair can drive and steer the wheelchair using a coupled drive unit. A drawback to the drive unit as described in the said patent publication is the complex coupling construction of the drive unit. It requires a great deal of effort to disconnect the drive unit or to connect it to the wheelchair.
- The present invention has for its object to provide a simplified auxiliary frame for a wheelchair which can be coupled to a wheelchair by a wheelchair user in very simple yet stable manner and which is also very simple to disconnect. Despite the simple coupling operation the coupling connection must be operationally reliable and stable.
- The invention provides for this purpose an auxiliary frame with the characteristic that the coupling means also comprise a stationary hook-like member connected to the elongate body. When the wheelchair and the auxiliary frame have to be coupled, the wheelchair user moves the wheelchair partly over the elongate body. The elongate body herein preferably urges the front part of the wheelchair upward such that the front wheels are lifted free of the ground. The coupling position is reached in that the hook-like member engages round a tube of the frame of the wheelchair. For the coupling the clamping bracket now only has to be displaced from a non-clamping position to a clamping position. The wheelchair user can thus mutually connect the wheelchair and the auxiliary frame in very simple manner with one hand. When disconnecting the auxiliary frame and the wheelchair the clamping bracket must be placed in a non-clamping position whereafter the wheelchair can be moved away from the auxiliary frame.
- A preferred embodiment is characterized in that the coupling means also comprise locking means, which locking means are formed by a member pivotally connected to the clamping bracket and a stop connected to the elongate body. These easy to operate locking means prevent undesired detachment of the coupling means.
- The drive means are preferably formed by a manual drive, by a combustion engine, by an electric motor or by a combination of these drives. These drives are relatively voluminous and/or heavy and usually particularly suitable for outdoor use. Particularly in the case of such drives it is attractive to be able to disconnect them from the wheelchair in small spaces.
- In a preferred embodiment the hook-like member is connected at an adjustable position to the elongate body. The distance of the wheel to the elongate body is preferably adjustable. With the above mentioned adjustment options an auxiliary frame can be adapted to wheelchairs of different dimensions.
- The wheelchair for use with an auxiliary frame as described in the foregoing is preferably characterized in that the wheelchair is provided with at least one connecting member connected to the wheelchair and consisting of an annular element placed round a tube for co-action with the coupling means. It is thus possible to guarantee a precise fit of the wheelchair to the coupling means. In addition the wheelchair frame can be protected against damage caused by the coupling means of the auxiliary frame.
- The wheelchair is further preferably characterized in that the connecting member is provided with at least one locating edge for positioning the auxiliary frame in relation to the wheelchair. It thus becomes possible to connect the auxiliary frame to the wheelchair at a desired position.
