ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a combined writing implement and turning tool, and more particularly, to a pen or pencil which is extendible and retractable on one end of the implement and a reversible rod which carries a Phillips head screwdriver, flat edge screwdriver, torx, Allen wrench, or other turning tool which is extendible and retractable on the other end of the implement. Alternatively, both ends may carry a turning tool, e.g. one flat head screw driver and one Allen wrench. Additionally, the end carrying the pen may be adapted to carry a carbide- or diamond-tipped stylus for keying pocket organizers or other devices which are too small to be keyed with the fingers or etching or marking glass or metal materials.
2. Description of the Related Art
The combination of writing implements and tools on the same holder is known in the art.
Nichols, in U.S. Pat. No. 2,190,910, describes an extendible/retractable writing implement which serves as a holder for a removable screwdriver. This implement has the disadvantage of requiring the removal of the screwdriver whenever its use is desired. This removal involves a plurality of steps. The separate screwdriver contains a short handle which is difficult to hold and turn and may become lost because of its small size.
Wu, in U.S. Pat. No. 5,638,566, describes a writing implement which is combined with a plurality of tools, including a Phillips head screwdriver and a flat head screwdriver. The writing implement and the tools are not extendible and retractable and remain exposed at all times. This presents the possibility of unsightly shirt pockets as the implement is intended to be carried in a shirt pocket. Also, the tool is constantly exposed and presents a danger, especially when the tool is a cutting blade. The screwdriver is attached to the casing by threads which turn when the screwdriver is used, tending to loosen the screwdriver. Any attempt to make the writing point and tools extendible and retractable would necessitate the destruction of the capability of the implement to carry a plurality of tools inside the implement.
The invention described and claimed in my earlier application, now U.S. Pat. No. 5,916,278 works well for its intended purpose. The manufacture of the patented device is more expensive than desired because of a multitude of small parts.
The present invention is designed to inexpensively provide the convenience of an extendible/retractable combination of a writing implement and a turning tool or two turning tools in a single implement while overcoming the disadvantages inherent in the implements of the prior art.
SUMMARY OF THE INVENTION
The present invention provides an implement which is a combination of a writing implement and a turning tool, a combination of a stylus and a turning tool, or a combination of two turning tools. A hollow casing contains a forward tip at one end through which a pen or pencil point, a stylus, or a tool rod may be extended or retracted. At the other end of the hollow casing is a flat surface having a non-circular opening through which a tool rod may be extended or retracted. The tool rod contains a turning tool on at least one end. This rod may be positioned such that either of the ends will be operational.
The casing contains at least one generally longitudinal slot. Each slot contains either a lateral opening or a longitudinal notch for holding an actuator guide pin, notch pin, or control button connected to an extension/retraction pin to enable the tip of the writing implement, stylus, and/or the tool rod to be extended, retracted, and held in place. Thus, with a single slot, only the forward work piece, only the rearward tool rod or neither of these will be exposed. When two slots are present, the forward work piece and the rearward tool rod may be independently moved.
In an additional embodiment, the casing contains a rearward primary longitudinal slot containing forward, medial and rearward latch openings or latch notches and a forward secondary longitudinal slot containing forward, intermediate, and rearward positions. In this embodiment, there is a forward work piece holder having an open forward end and a closed rearward end. The open forward end is used for holding an ink cartridge having a writing point on one end. The closed rearward end is tapered to a rounded point and may be used as a stylus.
With the actuator guide pin, notch pin, or control button in the medial position or forward position in the rearward primary longitudinal slot, the tool rod is retracted. With the actuator guide pin, notch pin, or control button in the rearward position of the rearward primary longitudinal slot in, the tool rod is extended.
When the control button in the forward secondary longitudinal slot is in the forward position, the forward work piece is extended allowing the forward work piece holder to be grasped and removed for easy reversal of position allowing either the stylus or ink cartridge to be operative. If the control button in the forward secondary longitudinal slot is in the rearward position, the forward work piece is retracted. If the control button in the forward secondary longitudinal slot is in the rearward position and the actuator guide pin or notch pin is moved to the forward position in the rearward primary slot, the forward work piece will be pushed forward in the forward secondary longitudinal slot so that it is in the intermediate position. In this position, the forward work piece is extended and the pen or stylus is operative.
