Devices, apparatus, systems, and methods for the quick installation of ceiling fan blades for ceiling fans. The invention uses a blade with three slots running in a linear direction from the mounting end of the blade, and three pre-attached fasteners upwardly projecting from the outer end of a blade arm. One of the fasteners is springably bendable with inwardly extending clip edge, another fastener that forms an upright post, and a third fastener having a top end with an outwardly extending lip edge. Another embodiment can include four slots per blade and four pre-attached upwardly protruding fasteners per blade arm. A novel method of installing each blade can include angling the blade to the mounting ends of the blade arm so that the outwardly extending lip edge catches on the third slot in from the mounting end of the blade. Next, the blade is laid down so that the other two slot openings pass over the other pre-attached fasteners while moving the mounting end of the blade toward the motor mounting end of the blade arm. This causes the springably bendable fastener to bend back and snapably spring back catching onto the first slot locking the blade to the blade arm.

The quick installation ceiling fan of claim 1, wherein one of the first fastener and the second fastener includes: an enlarged head with a sloped surface on top of a shaft wherein pushing down on the sloped top allows the fastener to bend downward until the enlarged head passes through one of the first slot and the second slot and snaps back in place locking the moveable bendable head portion to the one of the first slot and the second slot. 4. The quick installation ceiling fan of claim 1, wherein one of the first fastener and the second fastener includes: an inwardly directed overhanging clip edge directed toward the ceiling fan motor. 5. The quick installation ceiling fan of claim 1, wherein one of the first fastener and the second fastener includes an enlarged head with a gripable surface. 6. The quick installation ceiling fan of claim 1, wherein each blade arm includes: at least one grommet adjacent to the slots for reducing vibration and undesirable noise from the blades being attached to the blade arms. 7. The quick installation ceiling fan of claim 1, further comprising: a second middle slot between the first slot and the second slot. 8. The quick installation ceiling fan of claim 7, wherein the at least one upwardly extending post includes: two posts for the two middle slots, wherein the two middle slots are not in a straight line between the first slot and the second slot. 9. The quick installation ceiling fan of claim 8, wherein one of the first fastener and the second fastener includes: an inwardly directed overhanging clip edge directed toward the ceiling fan motor. 10. The quick installation ceiling fan of claim 7, wherein one of the fasteners includes: an enlarged head with a sloped upper surface on a shaft wherein pushing down on the sloped top allows the fastener to bend downward until the enlarged head passes through one of the first slot and the second slot and snaps back in place locking the enlarged head to the one of the first slot and the second slot. 11. A method of installing ceiling fan blades on a ceiling fan comprising the steps of: providing a plurality of blades each having mounting ends with a first slot located adjacent to a root end of the blade, a second slot adjacent to a tip end of the blade, and a middle slot between the first slot and the second slot;providing a plurality of ceiling fan blade arms each having motor mounting ends attached to a motor and blade mounting ends with a first upwardly protruding fastener adjacent to the motor mounting ends having a hook edge facing in a first direction, and a second upwardly protruding fastener spaced away from the first fastener having a hook edge facing in a second direction which is different from the first direction, and at least one middle post, with one of the first and second fasteners being bendable;angling the blades to the blade mounting ends of the blade arms so that the hook edge on one of the first and the second fasteners passes through one of the first and the second slots;laying down the blades over the at least one middle post while bending the bendable fastener; andlocking the blades to the blade arms when the bendable fastener is bent back in place into one of the first and the second slots. 12. The method of claim 11, wherein the first fastener, the middle post and the second fastener are positioned in a straight line on each blade arm. 13. The method of claim 11, further comprising: a second middle post on each blade arm, wherein the middle post is not in a straight line with the first fastener and the second fastener. 14. The method of claim 11, wherein the first hook edge and the second hook edge are in opposite facing directions. 15. A quick installation ceiling fan comprising in combination: a plurality of blades each of the blades having a first slot adjacent to a motor end of each blade, a second slot spaced toward a tip end of each blade and a middle slot adjacent between the first slot and the second slot; anda plurality of blade arms, each of the blade arms having a proximate end attached to a ceiling fan motor and a distal end, each blade arm having first fastener and a second fastener, and a middle post therebetween, with the first fastener located closer to the ceiling fan motor than the second fastener, the first fastener and the second fastener having hook edges, with one of the hook edges having a springably moveable head portion, the head portion being moveable up and down, wherein the blades are mounted to the blade arms by overlaying the slots over the fasteners, so that one of the hook edges clips onto one of the first slot and the second slot, and the moveable head portion of one of the first fastener and the second fastener snaps into another one of the first slot and the second slot. 16. The quick installation ceiling fan of claim 15, further comprising: a second middle slot adjacent to the first middle slot, and the middle post includes two upwardly protruding middle posts adjacent to one another. 17.
