ABSTRACT:
TECHNICAL FIELD
The present invention relates to sun protection devices and more particularly to an umbrella with a fan assembly that includes an umbrella assembly having a fan assembly located beneath a fabric canopy of the umbrella assembly; the umbrella assembly including a tubular vertical support tube having a handle at one end provided with a battery compartment and a fan motor activation switch, connecting wires running along the length thereof into connection with a fan motor of the fan assembly, and a collapsible rain canopy assembly including the fabric canopy attached to a collapsible canopy support frame in connection with the other end of the tubular vertical support tube; the fan assembly including a fan motor in controlled electrical connection with the motor activation switch through the connecting wires, a drive gear attached to an end of a motor shaft of the fan motor, a ring shaped fan blade assembly including a ring shaped fan gear rotatably mounted on a section of the tubular vertical support tube that is integrally formed with a fan blade attachment section having a number of pivot mounts each having a pivoting fan blade attached thereto such that rotation of the ring shaped fan gear about the tubular vertical support tube causes the pivoting fan blades to extend out radially from the fan blade attachment section, and a fan gear thrust bearing rigidly mounted to the tubular vertical support tube and limiting movement of the ring shaped fan gear along the tubular vertical support tube in a direction toward the handle; the fan motor being rigidly attached to the tubular vertical support tube such that the drive gear attached to the motor shaft engages the ring shaped fan gear in a manner to cause rotation of the ring shaped fan gear about the section of the tubular vertical support tube by rotation of the drive gear.
BACKGROUND ART
Although umbrellas are typically used as a shield against rain and the like, they are often used to shield a user from the sun during hot weather. Although the cover of the umbrella provides a sun shield to shade to a user, shade alone is often not sufficient to keep the user cool in hot weather. It would be a benefit, therefore, to have an umbrella that included an air moving device, such as a fan, to generate a cooling breeze directed at the user to provide cooling in addition to providing relief from sun rays.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide an umbrella with fan assembly that includes an umbrella assembly having a fan assembly located beneath a fabric canopy of the umbrella assembly; the umbrella assembly including a tubular vertical support tube having a handle at one end provided with a battery compartment and a fan motor activation switch, connecting wires running along the length thereof into connection with a fan motor of the fan assembly, and a collapsible rain canopy assembly including the fabric canopy attached to a collapsible canopy support frame in connection with the other end of the tubular vertical support tube; the fan assembly including a fan motor in controlled electrical connection with the motor activation switch through the connecting wires, a drive gear attached to an end of a motor shaft of the fan motor, a ring shaped fan blade assembly including a ring shaped fan gear rotatably mounted on a section of the tubular vertical support tube that is integrally formed with a fan blade attachment section having a number of pivot mounts each having a pivoting fan blade attached thereto such that rotation of the ring shaped fan gear about the tubular vertical support tube causes the pivoting fan blades to extend out radially from the fan blade attachment section, and a fan gear thrust bearing rigidly mounted to the tubular vertical support tube and limiting movement of the ring shaped fan gear along the tubular vertical support tube in a direction toward the handle; the fan motor being rigidly attached to the tubular vertical support tube such that the drive gear attached to the motor shaft engages the ring shaped fan gear in a manner to cause rotation of the ring shaped fan gear about the section of the tubular vertical support tube by rotation of the drive gear.
Accordingly, an umbrella with fan assembly is provided. The umbrella with fan assembly includes an umbrella assembly having a fan assembly located beneath a fabric canopy of the umbrella assembly; the umbrella assembly including a tubular vertical support tube having a handle at one end provided with a battery compartment and a fan motor activation switch, connecting wires running along the length thereof into connection with a fan motor of the fan assembly, and a collapsible rain canopy assembly including the fabric canopy attached to a collapsible canopy support frame in connection with the other end of the tubular vertical support tube; the fan assembly including a fan motor in controlled electrical connection with the motor activation switch through the connecting wires, a drive gear attached to an end of a motor shaft of the fan motor, a ring shaped fan blade assembly including a ring shaped fan gear rotatably mounted on a section of the tubular vertical support tube that is integrally formed with a fan blade attachment section having a number of pivot mounts each having a pivoting fan blade attached thereto such that rotation of the ring shaped fan gear about the tubular vertical support tube causes the pivoting fan blades to extend out radially from the fan blade attachment section, and a fan gear thrust bearing rigidly mounted to the tubular vertical support tube and limiting movement of the ring shaped fan gear along the tubular vertical support tube in a direction toward the handle; the fan motor being rigidly attached to the tubular vertical support tube such that the drive gear attached to the motor shaft engages the ring shaped fan gear in a manner to cause rotation of the ring shaped fan gear about the section of the tubular vertical support tube by rotation of the drive gear.
