This Application is a division of copending U.S. patent application Ser. No. 14/530,277 filed Oct. 31, 2014, owned by the Applicant hereof. The entire disclosure and drawings of the foregoing application are fully incorporated by reference herein.
BACKGROUND OF THE INVENTIONIt is a commonplace that articles being transported by vehicles often are much smaller in size than the cargo area in which they are placed. Without restraint, such articles may have a tendency to shift as the vehicle is accelerated, decelerated or turned, sometimes causing damage to the articles in question, the cargo area, or both. Cargo organizers and restraining systems have therefore been developed to stop the shifting or rolling of articles as they are being transported. Several such cargo organizers have been developed for relatively small articles or collections of same, as might be employed within the trunk of an automobile or the cargo area of a minivan. Representative of these are ones shown in Arico U.S. Pat. No. 7,306,416; Stanesic et al. U.S. Pat. No. 6,244,802 and Taylor et al. U.S. Pat. No. 6,012,885.
The problems associated with cargo shifting get worse as the size and mass of the article being transported grow. For larger and heavier items, such as might be transported in pickup trucks, the cargo restraining systems get more elaborate and require a good deal of buckling, tying down and/or other preparation before travel. Ideally, a cargo restraining system should be flexible enough to cage or restrain articles of different sizes, including possibly large articles or collections of same, and should be easy for the user to deploy.
SUMMARY OF THE INVENTIONAccording to one aspect of the invention, a cargo organizer has a base, including a base plate that is adapted to be placed underneath an article to be contained. At each of the left and right rear margins of the base, first and second upstanding, spaced-apart towers are formed. An upstanding, substantially planar first wall is positioned forwardly from the first tower and rearwardly from the base plate. An upstanding, substantially planar second wall is positioned forwardly from the second tower and rearwardly from the base plate. A right end of the first wall is joined to a left end of the second wall at an angle. A front surface of the first tower and a back surface of the first wall form a first board channel adapted to receive a first board of predetermined dimensions, which may be a milled piece of lumber of a standard size. A front surface of the second tower and a back surface of the second wall form a second board channel adapted to receive a second board of predetermined dimensions, which may be a milled piece of lumber of a standard size. The cargo organizer may be used with other, like cargo organizers to contain cargo, with or without the use of connecting boards.
In one embodiment there are a plurality of first towers and a plurality of second towers, respectively disposed, in spaced-apart relation, at the left and right rear margins of the base. Front surfaces of the first towers help to define the first board channel while front surfaces of the second towers help to define the second board channel.
Plural cargo organizers as above described may be used, with interconnecting boards, to create a cargo containment system. Each cargo organizer is positioned at a vertex of a polygon and each board is a side of the polygon. In one embodiment the polygon is a square or rectangle. The user may easy change the size or shape of the polygon by using interconnecting boards of different lengths.
According to another aspect of the invention, a base of a cargo organizer has a base plate that is adapted to be placed underneath an article of cargo. At least one upstanding wall is assembled to the base to bound the base plate. A lower surface of the wall has plural, spaced-apart, downwardly facing recesses, each of which have left and right margins. Located in between the left and right margins is a downwardly depending barb. The base has plural, laterally spaced-apart barb receivers that receive respective ones of the barbs. Each barb receiver has a central opening for receiving a barb, an upstanding left margin spaced to the left of the central opening, and an upstanding right margin spaced to the right of the central opening. When the wall is assembled to the base, the barbs are received by the receivers, the left margins of the wall recesses mate with the left margins of the receivers, and the right margins of the wall recesses mate with the right margins of the receivers. In this fashion, lateral movement of the wall relative to the base, and within the plane of the wall, is prevented.
In one embodiment, first and second walls are assembled to the base using barbs and receivers as above described.
According to another aspect of the invention, a base of a cargo organizer includes a base plate adapted to be placed underneath an article of cargo. At least one upstanding wall is assembled to the base at a channel disposed rearwardly of the base plate. A rear wall of the channel is sloped upwardly and rearwardly from a channel floor. The wall has a front web disposed adjacent to the base plate and spaced-apart reinforcing ribs that extend rearwardly from the front web. In a foot of the wall that is adapted for insertion into the base wall channel, rear ends of the ribs conform to the sloped surface of the rear wall of the wall channel of the base, such that the wall will be wedged into the channel of the base.
In one embodiment, the wall channel of the base is further defined by a plurality of upstanding plates that are disposed in alignment with a front edge of the channel. The front plates are disposed forwardly of the wall when the wall is assembled to the channel of the base. In one embodiment, the wall has a front surface that is disposed adjacent to the base plate. A plurality of relieved areas are formed adjacent to a bottom margin of the wall. Each relieved area has a surface that is rearwardly spaced from the front surface of the wall by a predetermined relief depth. The upstanding plates each have a thickness that is substantially equivalent to the relief depth. Each upstanding plate in the base is received into a respective relieved area of the wall when the wall is assembled to the base. The wall-receiving channel, as so defined, prevents motion of the wall relative to the base in a direction orthogonal to the plane of the wall. This rigidity enhances the strength of the connection of the wall to the base.
Further aspects of the invention and their advantages can be discerned in the following detailed description, in which like characters denote like parts and in which:
Referring to
One embodiment of this invention is sized to contain larger packages or collections of same. Hence, a radius of a front curved portion of the base plate margin 110, measured to the interior corner of walls 104 and 106, can be 6 inches, an assembled height of the organizer 100 can be 9.1 inches, a length from a left rear margin 112 to right front margin 114 can be 14 inches, and likewise a width from a right rear margin 116 of the base 102 to a left front margin 118 can be 14 inches. A length of base plate 108, from a forward surface 120 of wall 104 to opposed right front margin 114, can be 10 inches. A width of base plate 108, from a forward surface 122 of wall 106 to opposed left front margin 118, can be 10 inches.
The first organizer wall 104 may have several counterbored holes 124 sized to receive the heads of screws, and possibly washers threaded onto the screw shafts to be disposed immediately to the rear of the screw heads, so that the front end of each screw does not protrude beyond forward-facing surface 120. Second wall 106 may likewise have several such counterbored holes 124, so that the heads of screws inserted into them do not protrude inwardly beyond forward-facing surface 122. In the illustrated embodiment, each wall 104, 106 has a 2×3 array of screw holes 124, which are provided in vertically and/or horizontally spaced relation to each other. Advantageously, each wall 104, 106 can have one or more recessed holes 126 for tie-downs or bungee cords (not shown). The recesses 128 around holes 126 are sized and shaped to avoid having any part of a terminating fastener (such as a hook or knot) extend inwardly beyond forward wall surfaces 120, 122.
Walls 104, 106 further may have, near their top margins 130, 132, horizontally elongate handle holes 134, 136 that are sized for a user's hand to grasp. This permits the user to better manipulate and position the assembled cargo organizer 100 so as to be located underneath and adjacent the cargo load (not shown). Handles 134, 136 are so positioned that even after assembly of the organizer 100 to wooden or other crosspieces, as described below, they will be freely accessible by a hand of a user, who may then move an assembled cargo containment system as a unit (see
The body 202 of base 102, and the entirety of organizer walls 104, 106, may be injection-molded of a tough plastic such as high-impact polypropylene.

One inventive aspect of the cargo organizer 100 is that it can be used with other cargo organizers 100 to create a rigid box-like or other polygonal cargo containment system, a representative example of which is shown at 300 in
In a related embodiment, a cargo containment system 350, shown in
Walls 104 and 106 are shown in more detail in
Each of the walls 104, 106 has a plurality of spaced-apart barbs or prongs 404 on its respective lower edge or margin 406, 504. Each barb 404 projects downwardly within a respective downwardly facing recess 408 made in the lower edge 406 or 504 of the wall 104 or 106. Wall 104 has a vertical joining side or end 410 (here, the right end) opposite end 402. A plurality of inwardly facing openings or slots 412 are spaced apart in a channel near right margin 410. In the illustrated embodiment, the wall 106 is mostly a mirror image of the wall 104, with the exception that in the place of openings or slots 412, the joining side or margin 506 of wall 106 has a plurality of leftwardly and then downwardly extending hooks or fingers 508, each of which is adapted to be received into a respective opening 412 in wall 104. The position of hooks 508 and openings 412 alternatively could be reversed from the positions shown, or the joining side margins 410, 506 could have both hooks and openings.
As seen in
As injection-molded, many of the features of walls 104, 106 have sidewalls whose thickness, in a direction orthogonal to the respective planes of webs 414 or 510, exceeds the nominal wall thickness. As seen in
At the bottom of wall 104, a wall 432 defines part of the bottom of a board channel, as will be described in more detail below. Wall 432 extends in a backward direction orthogonally from the web 414. Each prong or barb 404, and each associated recess 408, is defined by a wall thickness substantially similar to the thickness of the board channel bottom wall portion 432, as are a series of reinforcing ribs 434 which extend downwardly from channel bottom wall 432 to the lower edge 406 of the wall 104. The portion of the organizer wall 104 at or below the bottom board channel floor portion 432 constitutes a foot 440 which is wedged into a wall channel of organizer base 102, as will be described below.

With reference to
As seen in
One form of a barb 404 is shown in
The barb 404 extends downwardly from recess upper surface 710 to a point at or near the bottom margin 706 of the wall 106, and can be centered within the recess 408. Margins 714 and 712 of the recess 408 are horizontally spaced from the barb 404. Barb 404 has a shank 715 with a predetermined horizontal width 716 taken in parallel to inner surface 122. The barb 404 terminates in a head 718 with horizontally extending portions or teeth 720, which may have backwardly and convexly curved surfaces. Back (upper) surfaces 740 of teeth 720 may be disposed at an acute angle, so as to force the engaged receiver tabs towards shank 715 upon any vertical tensile force applied between wall 106 and base 102, such as might be applied in an attempt to pull organizer wall 106 out from base 102. A lower end 722 of the barb 404 may be convexly curved in a direction orthogonal to the wall front surface 122, as shown. The curved surfaces on portions 720 and end 722 aid in registering each barb 404 in a respective barb receiver 212. Further, the curved surfaces on portions 720 reduce stress on rolled side walls or fingers of the receiving member 212 at their junctions with the rear channel walls and the front plates, in a manner which will be described below.
Referring now to
Each of the towers 210 has a vertical inner face 822 that may be sloped from the vertical. Particularly for tall towers, such sloping or draft may help in the injection molding of the base 102. Each tower inner face 822 is equipped with a plurality of forwardly extending fins or ridges 824. As best seen in
As seen in
Left finger 902 terminates in a right margin 914 that includes a central, downwardly and rightwardly protruding tab 916. The tab 916 may intentionally not be connected at its front or back ends (to plate 830 or sloped side 812) so that it will flex more freely when a tooth 720 of barb 404 cams over it. Right finger 904 terminates in a left margin 918 that includes a central, downwardly and leftwardly protruding tab 920 in opposition to the tab 916. The right tab 920 likewise may be intentionally disconnected at its front and/or back ends to plate 830 and sloped side 812 so that it will flex more freely when the opposed tooth 720 of barb 404 cams over it. A small amount of clearance between the barb teeth 1000, 1002 and the ends of tabs 916, 920 permit the barb 404 to overdrive past the tabs 916, 920, assuring that the tabs 916, 920 will snap in behind the barb teeth 1000, 1002. The back-inclined tooth surfaces 740 will, upon tensile force being placed on barb 404 relative to receiver 212, force tabs 916, 920 toward shank 715, preventing their disconnection.
To assemble the cargo organizer 100, the hooks 508 of the wall 106 are horizontally inserted into openings 412 of the wall 104, and the wall 106 is then vertically slid down into alignment with wall 104, as seen in
In summary, a cargo organizer and cargo containment system has been shown and described. The cargo organizer has upstanding walls which snap into a base in such a way that there will be no relative movement of the components after assembly. Each organizer further defines board channels for standard-sized lumber in order to construct a cargo containment system which can receive relative large and/or massive articles.
While illustrated embodiments of the present invention have been described and illustrated in the appended drawings, the present invention is not limited thereto but only by the scope and spirit of the appended claims.
