Elbow/Forearm-operated door opening device

thingiverse

This device was designed to let you use your forearm or elbow to open doors with standard, lever-shaped handles that are operated vertically and moved downward just like in this image: Using your elbow or forearm to open doors can significantly reduce exposure to pathogens, especially in areas at high risk of contamination during epidemics, such as hospitals or public places like shops or restaurants. The device is attached directly to the door handle without causing any damage. To help prevent the spread of COVID-19, Laitek Medical Software will make the design of these devices public and invite the community to take and share it with a suggestion to primarily target hospitals. Laitek Medical Software grants companies that want to take over the project for commercial purposes the right to do so in accordance with the Terms and Conditions document related to the package available for download. Usability This device can be mounted on door handles with the features specified in this drawing: Geometry Door insert element Shapes: conical, cylindrical, parallelepipedal Maximum angle of door insert element: 12 degrees Maximum thickness of insert element: 27 mm Minimum edge spacing: 12 mm from the door frame to the edge of the insert element 31 mm from the door to the inner edge of the lever Lever Shapes: conical, cylindrical, parallelepipedal, curved, wavy Height: 35 mm Thickness: 20 mm General model features The device is a single piece that consists of three plastic fasteners (zip ties, plastic clips) mounted onto the door handle. There are two versions of the model to cover both door opening directions - left / right. Mounting To mount this device, you only need three 3.5 mm thick and 30 cm long plastic fasteners (zip ties, plastic clips). Securing the zip ties once installed makes the process easier. Notice the wide loop created by the second zip tie. Note: We recommend securing the zip ties after insertion at a length of one centimeter from the top. Otherwise, especially when attaching the device onto the door insert element, it will be difficult to insert them once the device is in place. Insertion of the device onto the door handle Note: Notice the manner of insertion of the first loop. Securing the zip ties Note: Gradually secure each fastening element to ensure that the device is as secure as possible and makes maximum contact with the surface of various types of door handles it is mounted on. This handle will not fit all doors, so please check before purchasing.
