Fan assemblies and methods for assembling same

A blade arm comprising:

• a first connection portion structured for connection to a rotational member of a fan motor, where the rotational member is adapted to rotate about a rotational axis, wherein the first connection portion defines at least two openings therein, wherein the openings comprise an open end portion and a closed end portion, and wherein the first connection portion is configured so that, after at least two connection members are at least partially connected to the rotational member, the blade arm can be brought into a state of at least preliminary support from the connection members by sliding the first connection portion in a direction toward the rotational axis of the rotational member, while the rotational axis is vertically oriented, such that portions of the connection members move through respective ones of the openings;
• a second connection portion structured for connection to a fan blade;
• and
• an elongate portion positioned between the first connection portion and the second connection portion.

A fan assembly comprising:

• a motor including a rotational member driven by the motor;
• a connection member structured for connection to the rotational member and adapted to secure a blade arm to the rotational member, wherein the connection member comprises a head portion and a body portion;
• and
• a spacer defining an opening therein, wherein the opening comprises an open end portion and a closed end portion, wherein the opening is structured for receiving the body portion of the connection member therein, wherein said spacer is separate from the blade arm, and
• wherein the body portion of the connection member can be connected to the rotational member and positioned within the opening of the spacer, such that the spacer is positioned at least partially between the head portion of the connection member and the rotational member, and such that the head portion is maintained a predetermined distance away from the rotational member.

A fan assembly comprising:

• a rotational member;
• a connection member structured for connection to the rotational member, wherein the connection member comprises a head portion and a body portion;
• a spacer defining an opening therein, wherein the opening comprises an open end portion and a closed end portion, wherein the opening is structured for receiving the body portion of the connection member therein, and
• wherein the body portion of the connection member can be connected to the rotational member and positioned within the opening of the spacer, such that the spacer is positioned at least partially between the head portion of the connection member and the rotational member, and such that the head portion is maintained a predetermined distance away from the rotational member;
• and
• a blade arm defining a second opening therein, wherein the second opening comprises an open end portion and a closed end portion, and wherein the second opening is structured for receiving the body portion of the connection member therein,
• wherein the blade arm comprises a height dimension less than the predetermined distance, so that the blade arm can be positioned, in place of the spacer, between the head portion of the connection member and the rotational member.

An easy install fan assembly comprising:

• an easy install blade arm to motor connection comprising:
• a rotational member adapted to rotate about a rotational axis;
• at least two connection members structured for connection to the rotational member, wherein each of the connection members comprises a body portion and a head portion;
• and
• a blade arm defining at least two openings therein, wherein each of the openings comprises an open end portion and a closed end portion, wherein, when the blade arm is in a secure state, the head portions of the connection members at least partially bear against the blade arm, and wherein the blade arm and the connection members are configured so that, after the connection members are at least partially connected to the rotational member and while the rotational axis is vertically oriented, the blade arm can be brought into a state of at least preliminary support from the connection members by sliding the blade arm relative to the connection members such that the body portion of at least two of the connection members enters the open end of a respective one of the at least two openings as the blade arm slides in a direction towards the rotational axis of the rotational member;
• and
• an easy install blade arm to fan blade connection.
