Abstract
Devices for changing a light bulb (e.g., a compact fluorescent lamp or CFL), especially for those installed in high places, are disclosed. The device has a cylindrical tubular structure with one end opening to accommodate a light bulb. In one embodiment, at least one flexible thin arm with one end shaped to form a hook is pivotably affixed to the tubular structure. In another embodiment, a shaped insert is disposed in the tubular structure to provide necessary friction force to hold the light bulb in place during the changing process. The present invention is suitable for changing various types of CFLs.
Claims17
A device for changing a light bulb, the device comprising:
- a cylindrical tubular structure having a top opening to form an enclosed cup to accommodate the light bulb therein;
- and
- at least one flexible arm being pivotally attached to the cylindrical tubular structure and rotatable sideways, the arm having a hooked end, extended from an exterior of the cylindrical tubular structure, beyond the top opening of the cylindrical tubular structure and inwards to reach a recess portion of the light bulb, wherein the hooked end of the at least one flexible arm snaps onto the recess portion of the light bulb when the light bulb is accommodated to a certain depth of the cup, the at least one flexible arm is pivotally rotated sideways to release the hooked end off the recess portion of the light bulb so that the light bulb can be taken out of the enclosed cup.
A device for changing a light bulb with multiple tubes, the device comprising:
- a cylindrical tubular structure having a top opening to form a cup;
- a shaped insert removably disposed in the cup in the cylindrical tubular structure to accommodate the light bulb and cause the light bulb to rotate when the cylindrical tubular structure is caused to rotate, wherein the shaped insert is made from a flexible material and has an internal space formed to roughly match surface contours of the multiple tubes of the light bulb, inherent interference between some flexibility of the shaped insert and the multiple tubes of the light bulb provides a static friction for holding the light bulb;
- and
- at least one flexible arm being pivotally attached to the cylindrical tubular structure, the arm having a hooked end, extended from an exterior of the cylindrical tubular structure, beyond the top opening of the cylindrical tubular structure and inwards to reach a recess portion of the light bulb to hold up the light bulb.
