Description

Technical Field

[0001] The present disclosure relates to a personal fan device configured to generate sounds that may occur when used by spectators at sports events or performances. The novel portable fan device transitions between an open configuration and a closed configuration and includes a rattle and / or a clapper on the handle of the fan device. When the device is moved, the handle generates sounds by the rattle (rattling) and / or the clapper (clapping). A plurality of fan devices may be used to generate high-decibel sounds at an event.

Background Art

[0002] When many people participate in events such as sports events and performances, the ability to generate sounds to support or oppose aspects of a team, athlete, or performance enhances the event or performance experience. These people may shout, blow whistles, clap, or stomp their feet. Shouting or blowing whistles is tiring and difficult to sustain for a long time. Similarly, clapping can be tiring and may cause hand pain, and stomping the feet can cause fatigue and foot pain because it produces limited sound on certain structures such as concrete stands. All of these ways of generating sounds are difficult to maintain and may not be satisfactory because they cannot generate a large continuous sound without causing fatigue or discomfort to the sound generator.

[0003] Furthermore, many events are held outdoors or in locations where a portable fan would be useful. For example, at a baseball game, spectators may use a personal fan device to cool off. In these and other situations, the use of a compact and portable personal fan device is beneficial for various reasons, but at least some existing fan devices cannot generate the desired type or amount of sound.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, to enhance the experience of attending events and other experiences, there is a need for a sound generator with a fan form factor that is compact, portable, and personal, and can reliably generate a large amount of desired sound. This invention addresses this unmet need. [Means for solving the problem]

[0005] In one embodiment, the disclosure provides a fan device configured to transition from an open configuration to a closed configuration for storage or transport, and from a closed configuration to an open configuration for use. The fan device comprises a cover including a first member hinged to a handle and a second member hinged to a handle, the first and second members moving about one or more hinges relative to the handle. In the closed configuration, the fan device resembles a bat, such as a baseball bat.

[0006] The cover encloses the fan in a closed configuration and exposes the fan in an open configuration. In various embodiments, the handle includes a hollow space, the hollow space is provided with a number of beads configured to produce sound while the handle is moving, and / or the handle includes a clapper attached thereto, configured to produce sound while the handle is moving. The combination of beads and clapper can produce more sound than the beads alone or the clapper alone, and / or can produce a wider variety of sounds than the beads alone or the clapper alone.

[0007] In one embodiment, the fan comprises multiple blades, which are configured to transition between a closed configuration and an open configuration by sliding of the blades on each other and by rotating the blades about a pivot point. However, in an alternative embodiment, the fan may comprise a single sheet that is foldable along multiple folds. Thus, any suitable fan configuration may be implemented in a particular embodiment of the fan device.

[0008] In this embodiment, the handle is rigid and effectively transmits mechanical and sound vibrations, and the movement of the handle causes the beads to move and contact the inner surface of the handle defining a hollow space, thereby generating sound. As a result, the rattle can generate sound when the fan device is moved in any of the multiple directions or movements.

[0009] In this embodiment, the clapper comprises a first clapping member and a second clapping member, and the movement of the handle causes the first clapping member to strike the second clapping member, thereby generating sound. As a result, when the fan device is moved in a direction perpendicular to the plane of the clapper, the clapper can generate sound.

[0010] In this embodiment, the fan device further includes springs that bias the first and second members of the cover. The springs can bias the first and second members into an open configuration. In this way, the user can be assisted in opening the device.

[0011] In one embodiment, the fan device further comprises a hook and fastener positioned on the cover, the hook and fastener configured to maintain the fan device in a closed configuration. In another embodiment, a spring can bias the first and second members into an open configuration, and the hook and fastener hold the cover in a closed configuration against the biasing force of the spring.

[0012] The present invention relates to a novel fan device that can generally be manufactured using appropriate materials and processes and can be scaled up or down as required.

[0013] Other objects, features, and advantages of the present invention will become apparent from the following detailed description in conjunction with the accompanying drawings. [Brief explanation of the drawing]

[0029] Fan device This disclosure provides a novel portable personal fan device configured to generate sound when in use, for example, when used by spectators at sporting events or performances such as baseball games. The novel portable fan device transitions between an open configuration and a closed configuration and includes a rattle and / or clapper on the handle of the fan device. When the device is moved, the handle generates sound by the rattle and / or clapper. The fan device helps a person to easily generate sound at an event without needing to use additional or separate items to generate sound. In this way, the fan device is more convenient and effective for sound generation and can also be used as a fan to cool a person.

[0030] The following Figures 1A to 1I show some illustrations of the exemplary fan device of the present invention in a closed configuration with and without a clapper. Generally, the present disclosure provides a fan device 10 configured to transition from an open configuration (see Figure 1J) to a closed configuration (see Figures 1A to 1I) for storage or transport, and from a closed configuration to an open configuration for use. The fan device 10 comprises a cover 13 including a first member 13A and a second member 13B hinged to a handle 11, wherein the first member 13A and the second member 13B move around a hinge 21 relative to the handle 11. In the closed configuration, the fan device 10 resembles a bat, such as a baseball bat, as shown in the figure, and the cover may include an identification marking such as "Fan Club" as shown in the figure, or it may include the name of a sports team, the name of a performer, the name of a vendor, the name of a fan or person, the name of a company or product or service, etc.

[0031] In various embodiments, the cover 13 encloses the fan in a closed configuration and exposes the fan in an open configuration. In an embodiment, the handle 11 includes a hollow space in which a number of beads 20 configured to generate sound while the handle 11 is moving are provided (see Figure 4). The handle 11 may also have a clapper 19 attached to its bottom 15, configured to generate sound while the handle 11 is moving (see Figures 1F to 1I). The combination of beads 20 and clapper 19 can generate more sound and / or a wider variety of sound than the beads 20 alone or the clapper 19 alone.

[0032] The clapper 19 comprises a first clapping member (see 19A in Figures 3A to 3F) and a second clapping member (see 19B in Figures 3A to 3F). The movement of the handle 11, particularly the movement of the clapper 19 perpendicular to the plane, causes the first clapping member 19A to strike the second clapping member 19B, generating a clapping sound. In this way, the user can generate a clapping sound without necessarily clapping.

[0033] Hereinafter, Figure 1J shows a front view of an exemplary fan device in an open configuration. In an embodiment, the fan comprises a plurality of blades 12, which are configured to transition between a closed configuration and an open configuration by sliding the blades 12 on the blades 12 and rotating the blades 12 about a pivot point 14. In an embodiment, the fan and / or fan blades are made of textile material, plastic, paper, or any combination thereof.

[0034] Figures 2A and 2B below illustrate an alternative exemplary fan device in a closed configuration. In the embodiment, the cover may be optional or not present in a particular fan device or configuration. In such cases, the fan blades 12 may be visible or not covered by a cover, regardless of whether the fan device is in an open configuration (e.g., with the fan blades extended for use) or a closed configuration (e.g., with the fan blades retracted as shown in the figure). As shown in Figures 2C and 2D, the clapper 19 may be attached to the bottom 15 of the handle 11 and used to generate a clapping sound.

[0035] Figures 3A to 3F below show some illustrations of exemplary clappers according to the present invention. The clapper 19 includes a first clapping member flexibly attached to a mounting base 18B and a second clapping member flexibly attached to the mounting base 18B. The mounting base 18B can be attached to a corresponding mounting portion 18A on the bottom 15 of the handle 11 of the fan device 10, as shown in Figure 1E. In the illustrated embodiment, the mounting portion 18A is a female receiving portion (see 18A in Figure 4), and the mounting base 18B is a male member that is insertable into the female receiving portion and can be fixed to the female receiving portion by ribs of the male member that are flexibly fixed within the cavity of the female receiving portion. However, alternative connection means can be envisioned without departing from the scope of the present invention.

[0036] Figure 4 below shows a cross-sectional view of an exemplary handle with embedded beads according to the present invention. In this embodiment, the handle 11 is rigid and effectively conducts mechanical and sound vibrations, and the movement of the handle 11 causes the beads 20 to move and contact the internal surface 21 of the handle that defines a hollow space, thereby generating sound. The handle may be made of any suitable material, including but not limited to metal, plastic, carbon fiber, wood, or any combination thereof.

[0037] The following Figures 5A to 5C show some illustrations of exemplary fan blades according to the present invention. The fan blade 12 includes a narrow proximal portion 22 and a wide distal portion 23. The narrow proximal portion 22 includes an opening 12A, which allows the fan blade 12 to be rotatably mounted on a pivot point (see pivot point 14 of the fan blade in Figures 1J, 2A, and 2C). The movement of the fan blade 12 around the pivot point 14 allows the fan to be opened and closed when the fan transitions between an open configuration and a closed configuration.

[0038] Hereinafter, Figure 6 shows a top view of an exemplary fan device of the present invention in an open configuration. In the embodiment, the fan device 10 further includes a spring 14C that biases the first member 13A and the second member 13B of the cover from a closed configuration to an open configuration. In the embodiment, the fan device further includes a hook 16A and a fastener 16B disposed on the cover (13A, 13B) and configured to maintain the fan device in a closed configuration. The fan blades 12 overlap to some extent when in the open configuration, as shown in the figure.

[0039] Hereinafter, Figures 7A and 7B show illustrations of an alternative exemplary fan device in a closed configuration. In this embodiment, the fan device 10 includes pivot points (14A, 14B) for two fan blades and may further include a spring 14C that biases the first member 13A and the second member 13B of the cover 13 from a closed configuration to an open configuration. However, since the expandable fan includes hinges 14A and 14B that are not held in place by springs, the user may need to grasp both the left side 13A and the right side 13B of the handle 11 around the hinges in order to hold the fan in an open position. In the illustrated embodiment, the fan device 10 further includes a connecting structure 16 (e.g., a hook 16A and a fastener 16B (see Figure 6)) located on the cover 13 and configured to maintain the fan device 10 in a closed configuration. In this way, when the user grasps the handle 11 of the device 10, the device can be moved and sound can be generated without accidentally opening the cover 13 of the fan device.

[0040] Figure 8 below shows a cross-sectional view of an exemplary fan device 10 in which the fan blades 12 and / or cover members (13A, 13B) can be removed from the handle 11 by removing the screw-in pins 17B and screws 17A that secure the fan blades 12 and / or cover members (13A, 13B) to the handle 11. The fan device 10 may further include a spring 14C that biases the first member 13A and the second member 13B of the cover from a closed configuration to an open configuration. In this way, the use of the fan device 10 can be assisted by the biasing of the spring 14C.
