Description
BACKGROUND

Technical Field


The present invention relates to portable furniture, especially folding furniture. Aspects of the invention relate to folding tables, such as cook stations.


Discussion of Art


Folding furniture has been known. Folding tables in particular have been known. However, it is continually desirable to provide folding furniture—in particular, folding tables—that are of lighter weight, easier to carry, and with enhanced functional options.


SUMMARY OF INVENTION

In some embodiments of the invention, a cook station is provided as a slimfold table, i.e., one that can be folded substantially flat by comparison to bulkier prior art folding tables. One aspect of the invention is that legs of the slimfold table fold laterally outside the edges of central leaves of the slimfold table, such that in the folded condition, the folded legs surround the edges of the table leaves. Another aspect of the invention is that cross braces of the slimfold table fold laterally outside the legs of the slimfold table. Thus, the leaves, the legs, and the cross braces are laterally nested in their folded positions. This permits collapsing the table to a relatively small volume for transport or storage, by comparison to bulkier conventional folding tables.


In certain embodiments, the central leaves provide a heat-resistant folding counter top. In certain embodiments, the central leaves include latching means for supporting a load at least as heavy as a portable grill. In certain embodiments, the slimfold cook station is provided with side leaves as well as central leaves. In certain embodiments, the side leaves include edge receptacles that can be used in a variety of purposes due to their unique shapes. For example, the edge receptacles can receive any of wine glasses, table glasses, grill tools, a strap for holding rolled paper towels, or handles of a bag.


Certain exemplary embodiments of the invention, as briefly described above, are illustrated by the following figures.

DETAILED DESCRIPTION


FIG. 1 shows in front perspective view a folding furnishing, e.g., a slimfold table 10, which includes first and second pairs of legs 12 that are pivotally connected by an inner cross brace 14 and an outer cross brace 16. The legs 12 support a plurality of table leaves, specifically, inner leaves 18 as well as upper 20 and lower 22 side leaves.


Each of the pairs of legs 12 is connected by foot members 24 at their bottom ends, thereby forming U-shaped pairs of legs. Corner pieces 26 are mounted at the junctures of the upright legs 12 with the foot members 24. The corner pieces provide stability against rocking motions of the legs in their setup positions. The paired legs, however, need not be U-shaped. For example, each leg instead could be a straight piece 12 terminating at a foot member 24, with a pair of legs at each end of the table, the paired legs being connected by a cross brace in an H-shape. Connecting the legs in pairs, generally, enhances ease of use of the folding furnishing.


Each of the cross braces is U-shaped, thus, a cross brace, and has first and second side members that are joined by a cross member. The U-shapes of the cross braces permit of folding the legs and cross braces into a nested condition with the cross braces substantially surrounding the legs, as further discussed below.


The legs and the cross braces are fastened together by pivoting joints, so that they can be mutually moved among a deployed or setup condition as shown in FIG. 1, or a collapsed or nested condition as shown in FIG. 4, or any intermediate positions.


Referring to the inner cross brace 14, its cross member 28 is of a first length that is shorter than the cross member 30 of the outer cross brace 16. The side members 32 of the inner cross brace are generally flat and straight. By contrast, the cross member 30 of the outer cross brace is of a second length that is longer than the cross member 28 of the inner cross brace, and the side members 34 of the outer cross brace have crooked ends 36, so that the side members 32 of the inner cross brace are generally laterally nested within the side members 34 of the outer cross brace while the respective ends of the inner and outer cross brace side members are connected to the respective uprights 12.


The cross braces are pivotally connected to each other by center pins 40 (e.g., rivets or shoulder bolts), which are positioned at about the midpoints of the side members 32, 34. Between the inner and outer cross braces, the center pins 40 carry center bushings, which space apart the side members of the cross braces to permit nested folding. In particular, the center bushings position the inner cross brace 14 with respect to twisted links 44 that connect the outer cross brace 16 with the legs 12. This positioning of the inner cross brace 14 permits it to fold at least partly into the twisted links 44, as further described below and as shown in FIG. 4.


The side members 32 of the inner cross brace 14 are pivotally connected to the first pair of the legs 12 by top pins 46 at their top ends, and are pivotally connected to the second pair of the legs 12 by flat links 48 near the cross member 28. The top pins 46 carry top bushings 50 between the cross brace side members 32 and the first pair of legs 12, thereby spacing the side members of the inner cross brace 14 apart from the first pair of legs 12 so as to admit space for folding the twisted links 44 that are further described below. The flat links 48 are pivotally connected to the side members of the inner cross brace by link pins 52, and are pivotally connected to the second pair of legs by bottom pins 54.


The outer cross brace 16 is pivotally connected to the second pair of legs 12 by top pins 46 at its crooked ends 36, and is pivotally connected to the first pair of legs 12 by the aforementioned twisted links 44. Referring to detail FIG. 7, each of the twisted links 44 includes a flat body 56 with two arms 58 protruding symmetrically upward from sides of the flat body. One arm 58 of each twisted link is pivotally connected to one of the side members 34 of the outer cross brace by a link pin 52, while the other arm of each twisted link is pivotally connected to one of the uprights of the first pair of legs by a bottom pin 54. The twisted links 44 bridge across a lateral gap that exists between the outer cross brace side members 34 and the first pair of legs 12, in order to permit the nesting of the inner 14 and outer cross braces 16 as described above. In order to nest the side members 32 of the inner cross brace 14 into the twisted links 44, the center bushings 42 position the inner cross brace side members in registry with the flat bodies 56 of the twisted links, i.e., between the arms 58 of the twisted links. Thus, when the legs 12 are collapsed toward each other, the side members 32 of the inner cross brace 14 fold into the twisted links and are nested laterally between the side members 34 of the outer cross brace.


In order to provide for nesting of the legs 12 within the inner 14 and outer 16 cross braces, the link pins 52 are positioned between the center pins 40 and the respective cross members 28 or 30 of the cross braces 14 or 16, at a distance from the cross members so that a total folding distance F from the bottom pins 54 to the link pins 52 and back to the cross members 28 or 30 exceeds a linear distance L from the bottom pins 54 to the corner pieces 26. Thus, when the legs are collapsed together as shown in FIGS. 8 and 9, the links 44, 48 shift the cross braces 14, 16 downward relative to the legs 12, so that the legs can nest within the cross braces as shown in FIG. 4.


In order to prevent excess movement of the legs 12 when nested within the cross braces 14, 16, a locator peg 59 is provided at an inward surface of one of the inner cross brace side members 32.


For carriage of the slimfold table 10 in its collapsed condition, a handle 60 is provided on one of the side members of the outer cross brace.


The slimfold table 10, of course, does not consist only of the legs and the cross braces. In order to serve its primary purpose of being a table, the slimfold table includes inner leaves 18, upper side leaves 20, lower side leaves 22, and a wire rack 62.


The leaves of the slimfold table are collapsibly mounted onto the uprights of the legs 12 by conventional overcenter links. The inner leaves 18 preferably are fabricated of one or more heat resistant materials, e.g., enameled metal. At their adjacent mating edges, the inner leaves 18 can include one or more interlocking features, e.g., a tongue or tongues protruding from the underside of one or both of the inner leaves 18 to engage against the underside of the other inner leaf. The side leaves 20, 22 may be heat resistant, or may be lightweight polymers, or may be a heat resistant polymer such as silicone. Each of the side leaves 20, 22 includes hooks 64 and wells 66 for holding drinksware. The hooks also can hold straps, e.g., for a paper towel roll strap 67 as shown in FIG. 5.


The wire rack 62 includes two grates 68, which are pivotally connected with the cross members 28, 30 of the inner 14 and outer 16 cross braces, e.g., by hooking toes 70 of the grates into brackets 72 fastened to the cross members, as shown in FIG. 1. Alternatively, the grates 68 can be hooked into holes formed in the cross members 28, 30, as shown in FIG. 8. In any case, the grates 68 are movable between a deployed condition in which they extend horizontally toward each other between the cross braces, or a folded condition in which they extend generally parallel to and within the cross braces 14, 16. The grates 68 are disposed laterally within the side members 32, 34 so that the grates do not interfere with collapsing movement of the cross braces 14, 16. Each grate has cross bars 74 that are fastened to fingers 76. The fingers 76 of each grate 68 overlap the cross bars 74 of the other grate, so that the grates in their deployed positions interlock to provide rigidity of the wire rack. However, when the legs of the table are collapsed together, the grates can unlock and fold upward toward the legs so that in the nested or collapsed condition of the table the grates lay parallel and adjacent each other. In certain embodiments, the inwardmost cross bars of the two grates can be loosely fastened to each other, e.g., by a ring or the like, so as to maintain the interlocked arrangement of the fingers even when the grates are folded upward toward the legs.


Thus, the slimfold table 10 can be collapsed from its deployed condition, as shown in FIG. 1, to its folded condition, as shown in FIG. 4. In particular, the table leaves 18, 20, 22 first are folded down against the legs 12, as shown in FIG. 3. Then, as shown in FIGS. 8-9, a user unlocks the wire rack 62 while lifting and collapsing together the legs 12. Lifting and collapsing movement of the legs 12 causes the cross braces 14, 16 to pivot and nest as described above and as shown in FIG. 4.


Although exemplary embodiments of the invention have been described with reference to attached drawings, those skilled in the art nevertheless will apprehend variations in form or detail that are consistent with the scope of the invention as defined by the appended claims.
