If a hand-shaped object looks inviting to touch with your hands, does an elbow-shaped object look inviting to touch with your elbow?

Elbows don’t just give downward force.
You have to keep in mind that the levering force applied to the “prosthetic” is not linear, especially not with a clumsy elbow. Zip ties on two parallel contact points are not enough to resist the sideways forces.

Secure your prosthetic from multiple directions.
Three secure points around the lever, and one around the axis were enough to stop the sideways movement. This piece of wood fits most doorhandles due to the ability of the zip ties to adjust to the circumference of the handle. I used this base to attach my prosthetics.

Prosthetic needs to able to withstand downwards force.
The rain gutter was too weak to withhold the downwards force.

Do we take transport of materials into consideration for the accessibility?
I wasn’t able to transport this 2 meter rain gutter without the help of a car (and my mother who has a drivers license)

Doorhandle 2.1
Cornerpiece rain gutter door handle. A stronger alternative for doorhandle 2.0 that uses your elbow instead of your forearm.

Using Doorhandle 2.1 on a day-to-day basis.
I installed the doorhandle on my bedroom door, forcing me to use it.

If you CAN use it with your hand, you WILL.
No matter how well the doorhandle fit my elbow or forearm, i instinctively reached for it with my hands EVERY TIME.

“You have to sneeze in your elbow too now� ~ Thijs Uffen
This comment from Thijs during a meeting made me realize that elbow-operated doorhandles do not avoid the spread of the virus. An elbow-operated doorhandle will be just another surface to be contaminated.

How can we avoid with doorhandles ENTIRELY?
I stopped working on solutions that use your forearm or elbow From this point on I continued to work on the “Personal devices�, tools to use to avoid direct contact with objects.

“I want to hang up my clothes with that thing” ~Yuri Westplat There is no need to show the origin of the clothespin spring in the design. Although the “Grabber” device shares a part with a clothespin, it’s an independent product.

Wood is a material that is easy to process, and water resistant when coated.
used yachtlaquer that I obviously use for my yacht (I wish). This creates a waterresistant layer which makes this device washable.
