Description

FIELD

The disclosure relates to personal fan devices that are configured to generate noises, as may occur during use by a spectator at a sporting event or performance. A hand-held novelty fan device transitions between an open configuration and a closed configuration and includes a rattle and/or a clapper with the handle of the fan device. As the device is moved, the handle generates noise as a result of the rattle and/or the clapper. A plurality of fan devices may be used to generate high-decibel noises at an event.

BACKGROUND

Many individuals attend events, such as sporting events and performances, wherein the ability to generate noise in support of or in opposition to a team, a player, or an aspect of the performance enhances the experience of the event or performance. These individuals may vocalize or whistle, clap their hands together, or stomp their feet. Vocalizing and whistling may be exhausting and may be difficult to sustain for extended periods of time, clapping hands may be similarly exhausting and may lead to sore hands, and stomping feet may produce limited noise on certain structures such as concrete stands and may be exhausting and lead to sore feet. All of these approaches for noise production may be difficult to sustain and may be unsatisfactory due to their not producing loud and persistent noises without exhausting or causing discomfort to the noise producer.

In addition, many events are held outdoors or in spaces where a handheld fan may be useful to have. For example, attendance of a baseball game may lend itself to use of personal fan devices for cooling attendants. In these and other situations, the use of a compact, portable, personal fan device would be beneficial for a variety of reasons, but at least some existing fan devices may not generate a desired type or amount of noise.

Accordingly, there is a need for noisemaking devices with fan form factors that are compact, portable, and personal, and which can reliably produce large amounts of desired noises for enhanced event attendance and other experiences. The present invention addresses this unmet need.

SUMMARY

In one aspect, the disclosure provides a fan device configured to transition from an open configuration to a closed configuration for storage or transport and from the closed configuration to the open configuration for use. The fan device comprises a cover that includes a first member hingedly attached to a handle and a second member hingedly attached to the handle, such that the first and second members move about one or more hinges relative to the handle. In the closed configuration, the fan device may resemble a bat, such as a baseball bat.

The cover encloses a fan in the closed configuration and exposes the fan in the open configuration. In various embodiments, the handle includes a hollow space therein that comprises a plurality of beads therein configured to produce noise during movement of the handle, and/or the handle includes a clapper attached thereto configured to produce noise during movement of the handle. The combination of the beads and the clapper may produce more noise compared to the beads alone or the clapper alone, and/or may produce a wider variety of noises compared to the beads alone or the clapper alone.

In embodiments, the fan comprises a plurality of blades configured to transition between the closed configuration and the open configuration by slide movements of blades over blades and pivot movements of blades about a pivot point. However, in alternate embodiments, the fan may comprise a single sheet that is foldable along a plurality of fold lines. Accordingly, any suitable fan configuration may be implemented according to a particular embodiment of the fan device.

In embodiments, the handle is rigid and effectively conducts mechanical and sound vibrations, such that movement of the handle shifts beads to contact internal surfaces that define the hollow space of the handle to produce noise. The resultant rattle may produce noises when the fan device is moved in any of a plurality of directions or movements.

In embodiments, the clapper comprises a first clap member and a second clap member, and movement of the handle claps the first clap member against the second clap member to produce noise. The resultant clapper may produce noises when the fan device is moved in a direction perpendicular to a plane of the clapper.

In embodiments, the fan device further comprises a spring that biases the first member and the second member of the cover. The spring may bias the first member and the second member toward the open configuration. In this manner, the user may be assisted with opening the device.

In embodiments, the fan device further comprises a hook and a clasp disposed on the cover, such that the hook and the clasp are configured to maintain the fan device in the closed configuration. In embodiments, the spring may bias the first member and the second member toward the open configuration and the hook and clasp hold the cover in the closed configuration against the bias of the spring.

The invention generally relates to novelty fan devices which may be manufactured with appropriate materials and processes, and which may be scaled as needed in response to demand.

Other objects, features, and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.
