  • Patent number: 7806071
    Abstract: A bicycle bell includes a housing mounted on a handlebar and comprising a channel and an upward extending flange partially surrounding a top of the channel; a guide member secured to the housing; a drum secured to and covered the guide member; and a spring biased striking device mounted on the channel and comprising a bell lever and an opposite clapper extending through the flange to contact the guide member. Pivoting the bell lever about the channel will pivotably move the clapper to strike a first position on the drum after passing the guide member. Releasing the bell lever will return the clapper to its inoperative position after passing the guide member and striking an opposite second position on the drum. The bell is easy to manipulate with the same hand squeezing the brake lever.

An actuator rod may rotate the seat relative to the securing device, to actuate the clapper to strike against the bell member and to make sounds, without moving the bell member. A spring member may bias the seat to disengage the clapper from the bell member. The clapper may be caused to strike against the bell member when shaking or moving the bell member.
