Lever Arm Stress AnalysisCalculations are based on the static stress analysis done last semester.
Chair ReclineWhen the user is being removed from the wheelchair by the Hoyler lift, it is much easier for the care professional if the seat back can recline. A double point Remote Release Cable latch will be used to do so. The latch will be attached to the support bar behind the seat back by a cable tie or strap. This will allow the care professional to both release the latch and guide the chair tilt at the same time in order to ensure the patient's safety. Due to the limited strike size, the pin will most likely have to be mounted to the outside of the brackets at the bottom of the seat back. However, if mounted internal to the seat back, the frame will have to be cut so that the pin will penetrate both the bracket and the seat back. The final design can not be determined at this point of the build process. After the parallel link system is assembled and the weld points are determined, the final design of the latch mechanism can be determined.
Shin guard uprightA steel tube will be attached to the floor plate in order to securely press the shin guard to the passengers legs. This tube will be cut to size when more accurate measurements of the passengers legs are taken in order to ensure the best fit. An elastic band will also be fixed to the upright and will apply pressure against the passenger to keep her legs secure and allow her to stand.
Parts Order SummaryBelow is an image showing the current status of the parts that need to be purchased. 'On hold' in the Notes section means that this part relies on expert opinion and/or relies on the assembly of other sub-assemblies. These parts will be purchased at a later time. Each company has/will be contacted regarding its willingness to donate the parts to the project. In exchange we will advertise the company and generosity on our project display at the Imagine RIT festival and on this website.
The total estimated cost, not including potential donations, is ~$600. To view the current version of this file click on the following link Order Summary
