## Title
Drill driver multiple drive bit holder, screw cap container type

## Abstract

A detachable multiple drive bit holder for cordless and powered drill drivers, impact drivers, and drills, all referred from here on as drill drivers. This bit holder will hold multiple accessories and connect to drill drivers. Most drill drivers, particularly cordless drill drivers, have a slot in the body of the driver to hold spare drive bits. Drill drivers typically have only one of these slots, allowing only one spare driver bit. The driver multiple drive bit holder utilizes this single slot manufactured into the body of a drill driver to hold a container that stores multiple drive bits of various sizes.

PRIORITY DATE CLAIMED
Not Applicable.
FIELD OF THE INVENTION
The present invention relates generally to power and cordless tools of the drill driver type and more particularly to a drive bit holder adapted to be received in the standard spare drive bit holder of the drill driver.
BACKGROUND OF THE INVENTION
A variety of devices are available on the market for holding and storing drill driver drive bits. These devices come in a number of sizes and types that organize such drive bits in containers that attach to a drill driver. The major problem with the existing devices is that they are not necessarily compatible with all drill drivers because of the way they attach to the device, either through Velcro®, a self-adhesive pad or the type that screw into the frame of the drill driver. This method of attaching the drive bit storage could inherently pose the following issues:

    
    
        1. the tool may not have enough surface area to accommodate the method of attachment,
        2. the method of attachment needs additional space in the body of the drill driver to accommodate storage, and thus increases the size of the drill driver,
        3. the method of attachment is in such a way that it hinders the user to properly handle the drill driver,
        4. the method of attachment may cover cooling ducts on the drill driver, potentially causing the drill driver to overheat,
        5. the method of attachment could encroach on moving or electrical parts, potentially causing the drill driver to fail,
        6. the method of attachment could alter the manufacture's specifications, causing permanent damage to the drill driver,
        7. the method of attachment could come loose and pose a potential safety hazard during use,
        8. the method of attachment may not be approved by the manufacturer and could void the manufacturer's warranty.
    
    


Therefore, it is desirable to have a multiple drive bit holder that utilizes the manufacturer's drive bit slot already contained on the body of the drill driver. Such a device makes drive bits readily available in close proximity of the drill driver.

BRIEF SUMMARY OF THE INVENTION
In general the invention is implemented to improve the usability and convenience of a cordless/powered drill driver. The drill driver multiple drive bit holder, or apparatus, in particular improves the drive bit storage capability of a drill driver by allowing the user to store multiple driver bits instead of the standard single driver bit as provided by the manufacturer of the drill driver. The drill driver multiple drive bit holder utilizes this single slot to hold a container that stores multiple driver bits of various sizes. At one end of the apparatus is a machined rod shaped with a hexagonal cross-section exactly sized to the cross-section dimensions of the base of a typical drive bit. This rod can be inserted and retained in the drill driver's spare bit slot. Attached to this hexagonal cross-section will be a variety of drive bit holders.
The particular drill driver multiple drive bit holder described here is a screw cap container type. The screw cap container type will have a hollow cylindrical container with a screw cap connected to the hexagonal rod. The cylindrical container comes in different sizes and accommodates the storage of a variety of drill driver drive bits, for example slotted bits, Phillips bits, star drive bits, socket bits, and drill bits of different sizes. The entire apparatus can easily be attached and removed from the drill driver without the use of tools, simply remove or attach the apparatus to the drill driver's spare driver bit slot with a small force by hand.

DETAILED DESCRIPTION OF THE INVENTION
The detailed description of drill driver multiple drive bit holder, screw cap container type (referred to as the invention) refers to FIG. 5 which contains a side plan view with annotations of the invention.
The invention is made of a rigid material.
The invention is comprised of a screw cap (A) that has internal threading (B) near a bottom and a container (C) which has external threading (B) near an opposite top to allow the user to attach the cap (A) to the container (C) simply by rotating it on or off.
The container (C) is hollow on the inside with an open top and solid or closed bottom (F) which is where the user would store their drill driver accessories (e.g. drive bits and drill bits of a variety of types and sizes).
A hexagonal base (E) is attached to the container (C) by a spacer (D) and this hexagonal base (E) is that part which is inserted into the spare drive bit socket on the body of a drill driver as indicated in FIG. 6 by an arrow. The invention can be attached to and removed from the spare drive bit socket on the body of a drill driver by the user as often as needed.
CONCLUSION
It is apparent that variations of the invention can be constructed without departing from the main scope thereof. For example instead of a hollow container, referenced as the container type, the base of the invention could be comprised of a magnetic block upon which multiple spare drive bits for a drill driver could reside on because of their metallic/magnetic properties. Or instead of a hollow container the base of the invention could be comprised of multiple spare drive bit sockets as seen in FIG. 6 indicated by an arrow, arranged in a cylindrical pattern to hold multiple spare drive bits for a drill driver. The invention is not limited to a single type of power tool, but may be used with corded and cordless drill drivers, corded and cordless impact drivers, and with corded and cordless drills.
