DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention is directed to a magnetic tray. More particularly, the invention is directed to a magnetic tray which is collapsible and expandable. The magnetic tray in the collapsed position, as shown in FIG. 9, makes the tray easy to carry and transport when not in use. The magnetic tray when in the expanded position as shown, for example, in FIGS. 1 and 1A provides a substantial area for retaining articles in the tray and the tray may be closed and carried in the expanded position to another work area. The magnetic tray includes a first tray and a second tray connected to each other by the hinges of the magnetic tray and which may be closed or which first tray and second tray may be separated to provide two separate magnetic trays without a cover for closure. The first and second trays are the same or substantially the same making the expense of tooling, manufacture and assembling the magnetic tray simple and less expensive. Each of the first and second trays of the magnetic tray include a base on the inside of the magnetic tray with a magnet on the top side of the base for holding articles inside the tray and one or more magnets on the bottom side of the base for attaching the magnetic tray to a ferrous surface such as the underside of an automobile hood. FIGS. 1-9A show various aspects of the magnetic tray of the invention as discussed below.
Referring to FIGS. 1-1C, the invention is directed to a magnetic tray 10. The magnetic tray 10 comprises a first tray 10A connected to a second tray 10B. Trays 10A and 10B are the same or substantially the same. Referring, for example, to FIGS. 1-1C and 3-3B, tray 10A includes a body 12, a base 14, and a collar 16. Referring, for example, to FIGS. 1A-1C, tray 10B includes a body 12B, a base 14B and a collar 16B. It is understood that the first and second trays 10A and 10B are the same or substantially the same. In a preferred embodiment, tray 10A and tray 10B are the same. Accordingly, the description of the first tray 10A is the same for tray 10B. The parts of the tray 10A will be described in further detail below and the parts are the same for tray 10B followed by the letter “B.”.
Body 12 is made of a soft flexible material such polypropylene. Body 12 includes a front wall 20, side walls 22 and 24, back wall 26 and bottom wall 28. Each of these walls include a recess 30 and opening 32 for connecting the base 14 to the bottom of body 12 as discussed below. Bottom 28 incudes on the inside thereof four annular rings 34 for receiving magnets 58 as discussed below. Body 12 includes panels 36, 38, 40 and 42 and fold lines 44 and 46. Each panel 36, 38, 40 and 42 has a smaller width from the bottom panel 36 to the top panel 42, thereby allowing for the collapsing and expanding of body 12 along fold lines 44 and 46. Body 12 further includes openings 48 in each of the front, side and back walls for attaching collar 16 to body 12 as discussed below.
Base 14 is made of a hard plastic such as ABS (acrylonitrile butadiene styrene). Base 14 includes a first side 50 and second side 52. First side 50 is adapted to receive a magnet 54 preferably attached to the top side by an adhesive. Magnet 54 is preferably a soft magnet. Second side 52 includes annular rings 56 adapted to receive magnets 58 in the recess created by annular rings 56. Magnets 58 are preferably neodymium magnets. Annular rings 56 with magnets 58 seat in annular rings 34. Base 14 further includes clips 60 for attaching base 14 at the bottom of body 12 whereby the clips 60 extend through openings 32 of body 12 and are seated in recesses 30 of body 12 such that the clips are flush with the walls of body 12.
Collar 16 is made of a hard plastic such as ABS. Collar 16 comprises an outer collar 70 and an inner collar 90. Inner collar 90 seats inside body 12 adjacent to rim 29 of body 12 and includes spring clips 92 which extend through openings 48 in body 12 for connection to grooves 72 of outer collar 70. Referring, for example, to FIGS. 4 and 4A, outer collar 70B of tray 10B includes a snap lock 74B which includes a finger grip 76B and a locking lip 78B. Outer collar 70 further includes a recess or groove 80 for receiving the corresponding locking lip 78B of tray 10B.
Outer collars 70 and 70B include a hinge 100 comprising a hinge 100A on tray 10A and hinge 100B on tray 10B. Hinge 100A will be described herein with the understanding that hinge 100B is the same or substantially the same. Hinge member 100A includes a first hinge member 102 and a second hinge member 104. First hinge member 102 comprises a male member 110 and a female member 112. Male member 110 includes a crescent shaped pin 114 for ease of removal and attachment of the first and second hinge members 100A and 100B of tray 10A and tray 10B. Female member 112 has a wide entry point 116, approximately one half the circumference of female member 112, to allow male member 124B with pin 114B to be able to come apart and re-engage. First hinge member 102 further includes a hook 118 extending outwardly from the outer collar 70 and detents 120 and 122. The second hinge member 104 comprises male member 124 and female member 126 which corresponds in structure to male member 110 and female member 112, respectively, and a barrel 128 therebetween. Barrel 128 includes teeth 130 and 132 and a detent 134. When hinges 100A and 100B are connected as shown, for example, in FIG. 2B, the magnetic tray 10 may be opened and closed and maintained closed by snap locks 74 and 74B. Trays 10A and 10B will rotate from an open position to a position for separating the trays to 70°, 180° and 190° in a generally ratcheting movement.
As seen above, each hinge 100A,100B of tray 10A and tray 10B includes a hook 118,118B and a barrel 128,128B. The hook 118 of tray 10A meets up with the barrel 128B on tray 10B and the hook 118B meets up with the barrel 128 of tray 10A. This provides the snap/detent mechanism that allows the trays 10A and 10B to be positioned at multiple angles. The design further allows for the trays 10A and 10B to be separated if opened far enough, e.g. 190°, as shown in FIGS. 2E and 2F. Trays 10A and 10B when separated may be reattached to form magnetic tray 10 by reversing the process. Proper alignment of the hinges 100A,100B is required for the two parts to engage. Once engaged the hinge can be articulated. The male members 110,110B,124,124B and female members 112,112B,126,126B when aligned provide rotational stability to the hinge, keeping the entire hinge mechanism aligned as the hinge is articulated. Without these features, the hinge would not be able to keep on one common axis as the user tries to articulate the hinge. As noted, the pins 114,114B on the male members 110,110B,124,124B have a crescent shape to ease removal and attachment of the hinge. If the pins 114,114B were a complete cylinder the hinge would not be able to come apart and re-engage. Similarly, the female members 112,112B,126,126B have a wide entry point 116,116B to allow the male feature to engage and disengage easily. The combination of multiple male members 110,110B,124,124B and female members 112,112B,126,126B working together at different orientations throughout the rotation of the hinge provides the stability needed—as if the male and female members were built as uninterrupted cylinders, as one would have in a permanent hinge assembly—not a hinge designed to detach.
Tray 10 may be broken into two trays 10A and 10B as shown in FIG. 2F. The process is shown in FIGS. 5-8A and 2-2G. FIGS. 5 and 5A show the tray 10 in a closed position and the relationship between the female member 112 and male member 114B and corresponding to FIG. 2. FIGS. 6 and 6A show the tray 10 in a partially open position and shows the rotational movement of the male member 114B of the hinge in further relation to the female member 112 and corresponding to FIG. 2C. FIGS. 7 and 7A show the tray 10 in a fully open position and the further rotational movement of the male member 114B in relation to the female member 112, and corresponding to FIG. 2D. Referring to FIGS. 8 and 8A, tray 10B is moved downward to remove tray 10B from tray 10A, and corresponding to FIG. 2E. The male member 114 is now able to disengage from the female members 112. This cross-section is applicable to each of the male and female members of the hinges.
Referring to the Figures, there is shown various positions of tray 10. Specifically, FIG. 9 shows a front/side perspective view of both the first and second trays in a collapsed position. FIG. 9A is the tray of FIG. 9 in an open position. FIG. 1 is a front/side perspective view of the tray 10 in a closed position with both the first tray and the second tray in an expanded position. FIG. 1A is the tray of FIG. 1 in an open position. FIG. 2 is a front/side perspective view of tray 10 in the closed position with 10A expanded and tray 10B collapsed. FIG. 2D shows the tray 10 of FIG. 2 in a fully open position.
In use, tray 10 may be used in a number of configurations. For example, tray 10 as shown in FIG. 2, may be placed on the underside of an automobile hood with bottom 28 of tray 10A being magnetically attached to the hood. A worker may take parts from the automobile engine and place them in tray 10A to be held by magnet 54. Tray 10B in this instance may not be used and be open at a 70° angle. Similarly, the tray 10 of FIG. 1 may be placed on a horizontal metal surface adjacent a work area and parts or fasteners may be placed in the tray for use at the work area. In another use, trays 10A and 10B may be separated to provide for two separate trays wherein the trays are placed on a work area and magnetically adhered by the magnets 58 at the bottoms 28 and 28B of trays 10A and 10B and parts or fasteners maintained in trays 10A and 10B by magnets 54 and 54A. The uses are almost limitless.
Since trays 10A and 10B are the same, they may be made in the same mold. This saves on expense. Additionally, a purchaser may replace one of the trays with a new tray since hinges 100A and 100B are made to engage and disengage.
The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. As will be apparent to one skilled in the art, various modifications can be made within the scope of the aforesaid description. Such modifications being within the ability of one skilled in the art form a part of the present invention and are embraced by the appended claims.
