Introduction: FloorKnob - Hands Free Doorknob
A home-made FloorKnob will allow you to open most doors hands-free. This simple design is made of common household materials and can be non-destructively mounted to almost any doorknob or door handle.
To make one, you will need:
14" x 11" sheet of cardboard.
6' thin, strong cord (5/32" diameter paracord used in instructions)
3M poster hanging command strip
Box cutter or crafting blade
Lighter (for cord if applicable)
Step 1: Cardboard
Cut out a 14”x11” piece of cardboard.
If necessary, align pre-existing folds in the cardboard with the folds to be made.
Step 2: Cardboard
Cut along dash-dot lines, discarding corners.
Step 3: Cardboard
Fold Flap B underneath, creasing along the dashed line. Use a sharp tool to score the cardboard without cutting through to guide the fold if necessary.
Step 4: Cardboard
Fold Flaps D and E inward along dotted lines and unfold.
Step 5: Cardboard
Reinforce the indicated regions of Flap A with tape, folding the tape around the edges to cover both sides.
Step 6: Cardboard
Fold Flaps C and D downward along dotted line, scoring the cardboard as necessary.
Step 7: Cardboard
Lift cardboard and refold Flaps D and E to meet Flap B. Punch two holes approximately 1” inward in each direction from the corners of Flap C.
Step 8: Cord
Thread cord through the back of one hole, then under Flap A and through the front of the other hole. Tie a knot to secure. Tape joints and loose flaps securely.
Step 9: Cord Guide
Assemble and tape a cord guide if desired. This will keep the foot piece from swinging or getting between the door and the door frame. Attach it to the door with a command strip at roughly a foot above the ground. It may be advisable to mount this after the final height above the floor is chosen.
Step 10: Doorknob Attachment
Use scissors to cut a 3M poster command strip in half lengthwise. Attach the "wall side" adhesive to the top of the doorknob shaft. Expose the "poster side" adhesive and lay a section of cord on top. Wrap the cord tightly around the shaft at least five times such that the cord hangs off of the side not facing the door frame. Leave about six inches between the foot attachment and the floor.
Step 11: Complete!
