Cordless hairstyling tools with rechargeable and interchangeable batteries

A cordless curling iron device comprising:

• an elongated curling mandrel;
• a heating element operably connected to the curling mandrel;
• a handle extending from said curling mandrel;
• a removable battery housing containing one or more rechargeable batteries;
• said battery housing further comprising an outer face and a set of electric contact points operably connected to the one or more rechargeable batteries;
• said handle further comprising an indentation of substantially the same size as the battery housing, said indentation further comprising electrical contacts operably connected to the heating element;
• wherein the battery housing may be inserted into the indentation and secured in place, such that when the battery housing is secured in place, the outer face of the battery housing generally aligns with the edges and curvature of the indentation to form a curved outer face of the handle, and
• wherein, when the battery housing is secured in place, the electric contact points of the battery housing are electrically connected to the electrical contacts of the indentation, thereby allowing current to flow from the one or more rechargeable batteries to provide power to the heating element.

A cordless flat iron device comprising:

• a first elongated arm;
• a second elongated arm comprising a heating element;
• wherein said first elongated arm and said second elongated arm are attached at a pivot point;
• a removable battery housing containing one or more rechargeable batteries;
• said battery housing further comprising an outer face and a set of electric contact points operably connected to the one or more rechargeable batteries;
• said second elongated arm further comprising an indentation of substantially the same size as the battery housing, said indentation further comprising electrical contacts operably connected to the heating element;
• wherein the battery housing may be inserted into the indentation and secured in place, such that when the battery housing is secured in place, the outer face of the battery housing generally aligns with the edges and curvature of the indentation to form a curved outer face on the second elongated arm, and
• wherein when the battery housing is secured in place, the electric contact points of the battery housing are electrically connected to the electrical contacts of the indentation, thereby allowing current to flow from the one or more rechargeable batteries to provide power to the heating element.

A suite of cordless hair styling implements powered by one or more interchangeable and rechargeable battery packs comprising:

• (a) a removable battery pack comprising:
• a battery housing containing one or more rechargeable batteries;
• said battery housing further comprising an outer face and a set of electric contact points operably connected to the one or more rechargeable batteries;
• (b) a cordless hair dryer device comprising:
• a hair dryer housing;
• an electric fan supported in said hair dryer housing;
• an electric heater element supported in said hair dryer housing;
• said hair dryer housing further comprising a handle;
• said handle further comprising an indentation of substantially the same size as the battery housing, said indentation further comprising electrical contacts operably connected to the electric fan and the electric heater element;
• wherein the battery housing may be inserted into the indentation and secured in place, such that when the battery housing is secured in place, outer face of the battery housing generally aligns with the edges and curvature of the indentation to form a curved outer face of the handle, and
• wherein when the battery housing is secured in place, the electric contact points of the battery housing are electrically connected to the electrical contacts of the indentation, thereby allowing current to flow from the one or more rechargeable batteries to provide power to the electric fan and electric heater element;
• (c) a cordless curling iron device comprising:
• an elongated curling mandrel;
• a heating element operably connected to the curling mandrel;
• a handle extending from said curling mandrel;
• said handle further comprising an indentation of substantially the same size as the battery housing, said indentation further comprising electrical contacts operably connected to the heating element;
• wherein the battery housing may be inserted into the indentation and secured in place, such that when the battery housing is secured in place, the outer face of the battery housing generally aligns with the edges and curvature of the indentation to form a curved outer face of the handle, and
• wherein when the battery housing is secured in place, the electric contact points of the battery housing are electrically connected to the electrical contacts of the indentation, thereby allowing current to flow from the one or more rechargeable batteries to provide power to the heating element;
• (d) a cordless flat iron device comprising:
• a first elongated arm;
• a second elongated arm comprising a heating element and an indentation of substantially the same size as the battery housing, said indentation further comprising electrical contacts operably connected to the heating element;
• wherein said first elongated arm and said second elongated arm are attached at a pivot point;
• wherein the battery housing may be inserted into the indentation and secured in place, such that when the battery housing is secured in place, the outer face of the battery housing generally aligns with the edges and curvature of the indentation to form a curved outer face on the second elongated arm, and
• wherein when the battery housing is secured in place, the electric contact points of the battery housing are electrically connected to the electrical contacts of the indentation, thereby allowing current to flow from the one or more rechargeable batteries to provide power to the heating element;
• wherein when the battery housing is secured in place, the electric contact points of the battery housing are electrically connected to the electrical contacts of the indentation, thereby allowing current to flow from the one or more rechargeable batteries to provide power to the first and second heating elements.
