Patent no: 10,434,633
Issued: October 08, 2019
Inventor: Gravina
Attorney: Michael Feigin

Abstract

A disc for holding small parts to a drill, screwdriver, or other tool is disclosed. The tool has a rotating shaft, which it uses to function and the disc sits on this shaft stationary, while the shaft rotates, or, at least, rotates at a much lesser rate. The disc is also magnetic, so small parts, such as screws and other fasteners, as well as bits (e.g. drill bits and screwdriver heads) made of metal attach to the circular disc by way of magnetic force. In this manner, one can use the tool causing the shaft to rotate while holding the small parts to the circular disc situated on the shaft.

Description

FIELD OF THE DISCLOSED TECHNOLOGY

The disclosed technology relates generally to drilling accessories and, more specifically, to a disc for magnetically attaching fasteners while drilling.

BACKGROUND OF THE DISCLOSED TECHNOLOGY

"Where did I leave my screws?" and "Oh no, the nail rolled off the table!" are frequent thoughts running through the heads of people who are using electric tools. Fastening mechanisms such as screws and nails and other small metallic elements, including drill bits and screw driver heads, are easy to misplace. One has to operate the electric tool, or even a mechanical tool (such as a manual screwdriver) with typically one working end attachment at a time. This working end attachment (defined herein as "a removable or non-removable end which rotates in order to cause another device to also rotate or for a hole to be formed therein"). One then acts upon another object, such as a fastener, screwdriver head, or another material to fasten, cut, rotate, create a hole, or the like. Meanwhile, the other fasteners, bits, screwdriver heads, socket wrench heads, and those devices which are capable of being magnetized and having a longest length less than 10 centimeters (cm), 8 cm, or 5 cm (herein collectively referred to as, and defined as, "small parts") must be kept somewhere where they are not liable to be lost.

This is a known problem in the art. Some, such as Otho D. May, III, in his U.S. Pat. No. 6,496,094, have tried to solve this problem. In this patent Mr. May discloses a clamp which attaches around the body of a drill having a magnet on top to hold screws while drilling. Daniel Wallace Baird, in U.S. Pat. No. 5,842,584 acts similarly with a clamp around the outside having portals for larger items, such as pencils.

What is needed is a way to hold the smaller items to a drill which is easy to use and places small parts which one plans to use in connection with use of the tool in easy reach, so that one does not need to look away from his work or move the tool away. This would increase efficiency and decrease aggravation.

SUMMARY OF THE DISCLOSED TECHNOLOGY

A disc for holding small parts to a drill, screwdriver, or other tool is disclosed. The tool has a rotating shaft which it uses to function and, the disc sits on this shaft stationary while the shaft rotates, or at least, rotates at a much lesser rate. The disc is also magnetic, so small parts, such as screws and other fasteners as well as bits (e.g., drill bits and screwdriver heads) made of metal attach to the circular disc by way of magnetic force. In this manner, one can use the tool causing the shaft to rotate, while holding the small parts to the circular disc situated on the shaft.

A magnetic small part holding system of embodiments of the disclosed technology has a tool with an elongated shaft which rotates during a primary use of the tool. "Primary use" is defined as one of the intended uses by a manufacturer of the tool. Thus, a primary use of a drill or screwdriver is typically to make a hole or spin a fastener into a hole. Typically, an elongated shaft (or an "attachment mechanism" or "working end attachment," (as described in the detailed description) rotates as a result of the tool being used for it's primary purpose. A circular disc with magnet is also used with at least some equally sized sectors of the circular disc being of equal size and weight. The elongated shaft passes through a portal of the circular disc.

The portal has a smooth interior, in embodiments of the disclosed technology. In some embodiments, the elongated shaft has a first section with a circumference larger than a circumference of the portal, and a second section with a circumference smaller than the circumference of the portal. In such an embodiment, the circular disc can be situated between a) a frictional attachment mechanism of the tool (which frictionally holds the elongated shaft) and b) the first section of the elongated shaft having the larger circumference.

All sectors of a first and second circular side (top and bottom sides) of the circular disc are of equal size and weight, in some embodiments. A plurality of small parts is magnetically held to the circular disc at the top or bottom side. In use, the elongated shaft can be rotating, while the circular disc is stationary relative to the ground.

A method of using the magnetic small part holding system, in embodiments of the disclosed technology, includes grasping the tool, placing the circular disc around the elongated shaft, connecting the elongated shaft into a frictional attachment mechanism of the tool, and rotating at least the elongated shaft of the tool while using a business end of the tool. A step of magnetically attaching small parts to the circular disc before the step of rotating can also be carried out.

Another way of describing embodiments of the small part holding kit is as a circular disc with central portal, at least one magnet within the circular disc which is evenly weighted around the disc, and an elongated shaft extending through the central portal which is adapted to be, or is, held by a tool. The tool functions by way of rotation of the elongated shaft. At least one fastener can be magnetically held to the circular disc. The elongated shaft can have a first end with circumference greater than that of the central portal, and a second end with circumference less than that of the central portal. The shaft, in embodiments, rotates when the tool functions by way of rotation, while the circular disc remains stationary. An interior side of the portal which abuts the elongated shaft is smooth, in embodiments of the disclosed technology.

Any device or step to a method described in this disclosure can comprise, or consist of, that which it is a part of, or the parts which make up the device or step. The term "and/or" is inclusive of the items which it joins linguistically, and each item by itself.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSED TECHNOLOGY

A disc for holding small parts to a drill, screwdriver, or other tool is disclosed. The tool has a rotating shaft which it uses to function and the disc sits on this shaft stationary while the shaft rotates, or at least, rotating at a much lesser rate. The disc is also magnetic so small parts, such as screws and other fasteners as well as bits (e.g., drill bits and screwdriver heads) made of metal attach to the circular disc by way of magnetic force. In this manner, one can use the tool causing the shaft to rotate, while holding the small parts to the circular disc situated on the shaft.

Embodiments of the disclosed technology are described below, with reference to the figures provided.

FIG. 1 shows a cutaway view of a magnetic disc used in embodiments of the disclosed technology. The magnetic disc 10 has an outer shell 14 formed of a resilient solid, through which magnetic force can pass, such as a plastic or polymer. A magnet 12 is held within the shell 14, though in other embodiments the magnet can be partially or fully exposed to the outside. A portal 16 passes through the center region of the disc, sized to fit around a working end attachment, such as the working end attachment 30 shown in FIG. 2. The portal 16, in some embodiments, has a smooth interior surface, allowing the disc to remain in place or move at a substantially slower rotation on the order of 100 or more, while a working end attachment spins there-in.

FIG. 2 shows a tool and parts used with the magnetic disc, in embodiments of the disclosed technology. Here, a tool 20 is an electric tool (e.g., electric drill) or manual tool (e.g., manual screwdriver). In the embodiment shown in FIG. 2, the tool 20 is an electric tool, which has a rotating business end 22 and attachment mechanism 24, used to frictionally hold a working end attachment, such as working end attachment 30. In this case, the working end attachment 30 is an elongated shaft, with male and female ends oppositely disposed. A small part 32 (see definition in the `background`) attaches to the working end attachment 30.

FIG. 3 shows small parts attached to the magnetic disc situated on a working end attachment, in an embodiment of the disclosed technology. Here, a first small part 32 (screwdriver head) is inserted and frictionally and/or magnetically held with the attachment mechanism 30. A second set of small parts 40 (screws) are magnetically held to the magnetic disc 10. The attachment mechanism 30 passes through the portal 16 of the magnetic disc 10. The attachment mechanism can have a portion thereof with a larger circumference and a portion thereof with a smaller circumference. The portion with the larger circumference 33 has a circumference larger than the portal 16 of magnetic disc 10 such that the magnetic disc cannot slide there-over and fly off while being used. The smaller circumference 35 is of equal or smaller circumference than the portal 16 of the magnetic disc 10. It should be understood that the term "circumference" is a mathematical term known in the art and refers to the circumference of a circle--that is, the distance around the perimeter of a circle. Other terminology such as diameter, radius, and so forth, can similarly be determined for the circles shown, using well known mathematical principles.

Thus, one uses the device by placing the magnetic disc 10 around an attachment mechanism 30 such as by placing the attachment mechanism 30 through the portal 16 of the disc 10. Then one attaches the attachment mechanism to a business end 22 of a tool 20 and fastens it there-to, such with a friction to a frictional attachment mechanism 24. One then attaches a small tool, such as a fastener 40, the disc where it is held by magnetic force. When using the tool to rotate a shaft, such as the shaft of an attachment mechanism 30, such a shaft rotated within a stationary or more slowly moving magnetic disc 10.

FIGS. 4, 5, and 6 show further views of the magnetic disc 10. FIG. 4 shows a top perspective view of a magnetic disc used in embodiments of the disclosed technology. FIG. 5 shows a top plan view of the magnetic disc of FIG. 4. FIG. 6 shows a side view of the magnetic disc of FIGS. 4 and 5. The magnetic disc 10 has an outer shell 14 and inner rim 18 rising about the plane of the outer shell, in some embodiments of the disclosed technology. A portal 16 passes there-through. The magnetic disc 10 is weighted and sized equally in all radial directions. Thus, any two equally-sized sectors (using the mathematical definition of a sector of a circle) are of equal size and weight (defined as "within an acceptable tolerance level known in the industry, such as within 1%, 0.1%, or 0.01%").

While the disclosed technology has been taught with specific reference to the above embodiments, a person having ordinary skill in the art will recognize that changes can be made in form and detail without departing from the spirit and the scope of the disclosed technology. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope. Combinations of any of the methods, systems, and devices described hereinabove are also contemplated and within the scope of the disclosed technology.
