MAGNETIC CASSETTE FOR POWER TOOL MOUNTS

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority from U.S. Provisional Patent Application No. 63/030,600 filed May 27, 2020, such application is expressly incorporated by reference herein for all purposes.

FIELD OF THE INVENTION

The present invention pertains to the field of mounts for reversible securing of power tools to ferromagnetic materials such as metals containing iron.

BACKGROUND OF THE INVENTION All of the publications, patents and patent applications cited within this application are herein incorporated by reference in their entirety to the same extent as if the disclosure of each individual publication, patent application or patent was specifically and individually indicated to be incorporated by reference in its entirety.

The use of mounting brackets attached to power tools to assist in their storage by removable fixation to a bracket or ferromagnetic material is known in the art. For example, U.S. Pat No. 10,654,163 issued to Flurst as of May 19, 2020, describes a magnetic mount, which may be attached to a power hand tool, so as to allow it to temporarily attach to a magnetic surface when in a non-operating state. Further, U.S. Pat. No. 4,639,170, issued to Palm, describes the use of magnets, to reversibly attach the lower assembly of a power tool, providing additional stability during use of the power tool, rather than reversible attachment of the power tool in a non-operating state. U.S. Pat. No. 10,625,411 issued to Tesoroni; describes a mount for a tool which comprises a clip, for friction attachment to a tool, which also provides a magnet for attachment of the mount, and tool when using the friction based attachment, to a ferrous, or ferromagnetic, surface. Of note, is that Tesoroni teaches a mount capable of removal from the tool, when non-operational. The prior art has provided for power tool mounts where the tool may be attached by way of a magnet to ferromagnetic surfaces, for reversible attachment and storage when the tool is in the non-operational state. Yet the art has suffered from the magnet, present on the mounting bracket on the tool, being present during the operation of the power tool. When operating the power tool in open spaces, this is of limited consequence; but when in tight or crowded environments where the presence of the magnet can cause interactions with electrical, electronic or ferromagnetic surfaces; where the utility of the reversible magnetic mount is overcome by the negative interactions of the magnet during its operations. Further, the powerful magnets providing the force necessary to reversibly adhere the mount and power tool assembly to a ferromagnetic surface, such as a ferrous metal, are often brittle and susceptible to shattering when subject to impact; with the replacement of the magnet can require replacement of the entire mounting element. Finally, the prior art has failed to provide for a magnetic mount for the easy removal or replacement of the magnet within the mounting bracket; whether to provide for a magnet with differential magnetic power, replacement of the magnet following its shattering or breakage, or temporary removal of the magnet when the power tool is in operation in close quarters or where the presence of the magnet would otherwise be unwanted.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

The present invention contemplates the use of a magnetic cassette capable of being reversibly fixed within a mounting element, the mounting element further fixed to power hand tool. The present invention is intended to be used with and incorporate a mount attached to a power tool, wherein the magnetic element incorporated into the mount may secure the power tool to a ferromagnetic material, such as a ferrous metal, while the power tool is not in use. The mount contemplated by the present invention includes: a) a substantially u-shaped bracket including a spaced apart pair of mounting arms each having a base end and an opposite distal end, a rigid cross memberjoining the pair of mounting arms at the base ends; b) a mounting head on each distal end of the pair of mounting arms; c) at least one magnetic cassette capable of being reversibly attached to the cross-member; d) wherein the pair of mounting arms are disposed in a first direction from the cross member and the at least one magnet is disposed in a second direction substantially opposite to the first direction, from the cross-member; and e) wherein the mounting heads are adapted for mounting to at least one side of the power tool. As used herein, the term “magnetic material” means a material having ferromagnetic or strong paramagnetic properties. Suitable magnetic materials include magnetite, ferrites, hematite, maghemite, neodymium, pyrrhotite and metals, alloys and compounds containing iron, nickel, or cobalt.

The present invention contemplates use of a magnetic cassette with a power tool mount, comprised of a material that does not interfere with the magnetic field generated by the magnet contained within. Optionally, the present invention contemplates utilization of a housing material designed to focus or orient the magnetic field generated by the internal ferromagnetic material; for example focusing of the magnetic field to increase the magnetic force experienced by a ferromagnetic material to the housing such as a ferrous surface to which the mount, with the magnetic cassette fixed within it, would reversibly attach to.

FIG. 1 shows one embodiment of the present invention, comprising a mounting element 101, with a magnetic cassette 102; wherein the magnetic cassette is designed to be reversibly fixed within the mounting bracket which comprises mounting arms 106 and a rigid cross member defining an inner cavity 105. In this embodiment, the magnetic cassette is reversibly fixed to the mounting element 101 via lateral clips, 103, with a biased offset from the lateral planar surface of the magnetic cassette 102, and located on both sides of magnetic cassette 102 (only one set of lateral clips is shown). Lateral clips 103 are designed to pass through lateral apertures 104, with the biased offset of lateral clips 103 established such that lateral clips 103 pass through lateral apertures 104 and prevent complete dislocation of cassette 102 when seated in the inner cavity 105 of mounting element 101, with lateral clips 103 seated within lateral apertures 104. It is contemplated that there will be some movement of the magnetic cassette 102 within the mounting element, even with seating of lateral clips 103 within lateral apertures 104, the extent of which determined by the choice of thickness of lateral clips 103, the extent of the offset bias on lateral clips 103, the size of lateral apertures 104; all of which are within the knowledge of one skilled in the art, to modify to provide the desired movement, or limitation of movement, of the magnetic cassette 102 once seated within mount 101.

Removal of the magnetic cassette 102 from the seated position in mount 101 (not shown) occurs through application of pressure on the offset biased ends of lateral clips 103 towards the lateral plane of magnetic cassette 102, allowing the passage of the lateral clip through the lateral aperture. The total width of magnetic cassette 102, with the offset biased ends of lateral clips 103 compressed onto the surface of the lateral plane, must be less than width of the inner cavity, 105 of the mount 101. FIG. 2 shows magnetic cassette 102, comprised of a housing 201 surrounding a ferromagnetic material (not shown), with lateral clips 103 attached to the outside of the housing 201, the figure more fully demonstrating the offset bias of the lateral clips, the bias increasing from the attachment point of the lateral clip onto the magnetic housing 201. It is contemplated that housing 201 surrounds at least a magnet, providing the desired magnetic force when in close proximity of a ferromagnetic material. For applications where a varied attractive force between the magnet and a ferromagnetic material is desired, it is contemplated that either a magnet providing a lower magnetic force may be included in the housing, or alternatively a magnetic material with set magnetic strength per unit volume is utilized, but the volume of magnet incorporated within the housing either increased or decreased so as to vary the magnetic force experienced by an adjacent ferromagnet; with the housing either remaining empty, or in a preferred embodiment a non magnetic filler chosen such that it has a similar density to the magnetic material but without substantially interfering with the magnetic field experienced by the adjacent ferromagnetic material, so as to maintain the expected balance of the mount while modifying the magnetic force experienced when the mount, with the cassette in a seated position, is brought near to the ferromagnetic material.

FIG. 3 shows a side profile of mount 101 with the magnetic cassette (not shown) within the mount, with the lateral clips 103 seated within the lateral aperture 104.

FIG. 4 shows an alternative embodiment of the present invention, with magnetic cassette 401 designed to insert in the mount 402 by use of dowel, 403, which passes through circular aperture 404; and which is held in place, once passed through circular aperture 404, by use of a “circlip” or “c-clip” style retainer 405, made of a semi-flexible material, which may be inserted into annular grooves (not shown) machined in dowel 403 to receive retainer 405. The elements are designed such that when cassette 401 is seated within the mount 402, with dowel 403 passing through circular aperture 404, and retainer 405 itself seated into the annular grooves in dowel 403; that lateral movement of the dowel, and therefore the cassette within the mount, is not permitted. In one embodiment, cassette 401 does not fully enclose magnet 406; which may slide laterally into cassette 401 , and is constrained within the cassette by sidewalls 407 forming part of mount 402, which form a partial or complete (not shown) cup, with the sidewalls preventing movement of magnet 406 within cassette 401, when the cassette is seated within mount 402.

FIG. 5 provides further details of the alternative embodiment presented in FIG. 4, including a top-down and side view of circlip style retainer 405, dowel 403 containing annular grooves 501 to receive circlip style retainer 405. Dowel 403 can be of a length sufficient to pass through the aperture and bottom plate of the mount, such that the circlip can be inserted into annular grooves 501. FIG. 6 shows one embodiment of the present invention, with magnetic cassette (not shown) seated within mount 401; with dowel 403 and annular grooves (not shown) to receive circlip 405, designed to allow circlip 405 to provide a substantially flush mount against bottom plate, 601, of the mount 401.

While particular embodiments of the present invention have been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention and are intended to be included herein. It will be clear to any person skilled in the art that modifications of and adjustments to this invention, not shown, are possible without departing from the spirit of the invention as demonstrated through the exemplary embodiments. The invention is therefore to be considered limited solely by the scope of the appended claims.
