It may be concluded that, by use of the newly developed Swing-Turn-gear system, mobility of the disabled person using wheelchairs outdoors can be improved. The qualities of the drive gear in push and pull action, the free wheel, the full selection of frequency, and the range of moving the hand levers represent important progress in wheelchair engineering research. The handrim drive is an alternative, especially for indoor use. But, for the first time, an indoor wheelchair can be offered as a combination vehicle for both indoor and outdoor use. The acceptance of the new wheelchair integrated Swing-Turn-gear is much better than the conspicuous hand-lever drive in standard outdoor wheelchairs. At present, the German wheelchair manufacturer, MEYRA Vlotho, is preparing the new hand-lever drive system for production. Initially, the drive system will be adapted to a standard indoor wheelchair made by this company. Development of a lever drive system is also in progress in the United States, which employs force transmission characteristics in one direction.
可以得出结论，通过使用新开发的摆动转向齿轮系统，使用轮椅的残疾人在户外的行动能力可以得到提高。驱动齿轮在推拉动作、自由轮、频率的全面选择以及手摇杆移动范围方面的特性代表了轮椅工程研究的重要进展。轮圈驱动是一种替代方案，尤其适用于室内使用。但是，首次可以提供一种既适用于室内又适用于室外的组合式室内轮椅。新型集成摆动转向齿轮轮椅的接受度比标准户外轮椅中引人注目的手摇杆驱动要好得多。目前，德国轮椅制造商迈拉·弗洛托正在准备生产新的手摇杆驱动系统。最初，该驱动系统将适配该公司生产的标准室内轮椅。美国也在进行杠杆驱动系统的研发，该系统采用单向力传递特性。
