Donkey Calf Razor
by GrabCAD
Last crawled date: 1 year, 11 months ago
This is my first submission to the "Donkey Calf Raise Attachment Challenge" for 3D Technology in association with GrabCAD.
My design has taken the utilitarian purpose of the workout device and given it a boosted aesthetic presence, while improving the overall design.
The most noticeable difference is the shape. The pads have been contoured in a way that would support and spread the weight across the lower back. The firm rubber or foam padding would be wrapped in leather vinyl to prevent sweat from soaking into them, but they would be soft enough as to not make the user uncomfortable. The contoured shape would reduce the risk of injury and ease the users mind.
The plate that the pads are mounted to follows the same contour, making the design feel whole and complete. Not only does it improve the appearance, but the "bowl" like shape adds much needed strength to the device. This plate would be made from 1/4" stamped steel and powder coated to suit the customers desires.
The clamping unit emerges gracefully out of the plate's surface and makes clamping easy and foolproof for the user. Since the hinge only needs to support the weight of the device itself, it does not have to be overly robust. Two simple hand screws allow the user to secure the weightlifting bar onto the Donkey Calf Razor. The clamping unit would be made of either high density plastic or forged steel and it is secured to the metal plate by hidden screws underneath the pads.
The clamping unit also integrates poly-urethane bushings, which allow the unit to swivel when it is being used, giving the customer added comfort.
This device is compact and lightweight in comparison to the original, but all of the materials and manufacturing methods used would keep the costs low making it a good fit for the customer and 3D Technology.
Thank you for viewing my project!
Special thanks to Armin Yousefi Kanani for uploading a reference model of the Smith Machine.
UPDATE: I added some thickness to the padding to increase the users comfort as well as making the base plate thinner to reduce weight.
