Abstract
Abstract A magnetic drill holder is comprised of a nonmagnetic housing and a magnetic back plate. The housing is fabricated as a series of adjoining longitudinal channels, each having one closed end. A common magnetic back plate encloses the channels longitudinally, thus forming longitudinal receptacles. The channels may be of varying lengths and areas, making them suitable for holding a series of tools, such as drill bits. Magnetic tools placed in the receptacles are retained in them by magnetic attraction. The tool holder further includes a pocket that utilizes the magnetic back plate and a housing rib to hold a selected tool, such as a drill chuck key, in the tool holder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A magnetic tool holder for holding and storing a plurality of magnetic tools comprising: (a) a housing having a plurality of adjoining generally U-shaped longitudinal channels, each channel being defined by a pair of spaced side walls, a top wall, and a transverse end wall; and (b) a magnetic back plate attached to the housing to longitudinally enclose the channels to create a plurality of open ended elongated receptacles, so that magnetic tools inserted into the receptacles are retained in place by the common magnetic back plate.
Claim 2
Dependent Claim
87 words
A magnetic tool holder for holding and storing a plurality of magnetic tools comprising: (a) a housing having a plurality of adjoining generally U-shaped longitudinal channels, each channel being defined by a pair of spaced side walls, a top wall, and a transverse end wall; and (b) a magnetic back plate attached to the housing to longitudinally enclose the channels to create a plurality of open ended elongated receptacles, so that magnetic tools inserted into the receptacles are retained in place by the common magnetic back plate.
Claim 3
Dependent Claim
29 words
The magnetic tool holder of claim 1 wherein the longitudinal tool holding receptacles are of different areas and lengths to accommodate a variety of tool cross sections and lengths.
Claim 4
Dependent Claim
24 words
The magnetic tool holder of claim 2 wherein the tool holding receptacles are arranged sequentially by size to accommodate a range of drill bits.
Claim 5
Dependent Claim
32 words
The magnetic tool holder of claim 3 or claim 2 wherein the tool holding receptacle open ends are coplanar, so that the channel end walls and side walls create a stepped surface.
Claim 6
Dependent Claim
127 words
The magnetic tool holder of claim 4 wherein: (a) the housing further comprises: i. a pair of intersecting border strips formed integrally with and extending from the U-shaped channels to enclose the stepped surface and to create an opening in the plane of the channels; and ii. a rib formed integrally with and extending between a border strip and a U-shaped channel and defining a slot therein; and (b) the magnetic back plate covers the housing opening in the plane of the channels to create a pocket and to enclose the rib slot thereby forming an aperture through the rib, so that a selected magnetic tool may be inserted through the rib slot and placed within the pocket and against the magnetic back plate for secure retention.
Claim 7
Dependent Claim
111 words
The magnetic tool holder of claim 5 wherein: (a) the channel side walls end in a common plane; (b) the housing is formed with a pair of outside walls having a back surface; (c) the border strips have a back surface coplanar with the outside walls back surface; (d) the outside wall and the border strips are formed with stepped surfaces coplanar with the ends of the channel side walls; and (e) the magnetic back plate is received in the steps in the outside walls and border strips, the magnetic back plate being thicker than the depth of the steps, so that the magnetic back plate protrudes beyond the back surfaces.
Claim 8
Dependent Claim
29 words
The magnetic tool holder of claim 1 or claim 6 wherein the housing further comprises at least one hook adapted to engage the user's belt or pants belt loop.
