›DETAILED DESCRIPTION OF THE EMBODIMENT OR EMBODIMENTS · 1 of 2
FIG. 1 illustrates a modular trivet member 102 in the form of a cross with a main support 104 having a cross-section in the form of a substantially rectangular bar, and a cross support 106 with a similar cross-section. At the ends of the main support there are feet 108 , 110 , and the cross support has similar feet 112 , 114 . These feet make the modular trivet member self-supporting. The feet provide good stability for the trivet member as the feet are located at the ends of their associated bars, so loads are applied inboard of the feet. The intersection 126 between the main bar 104 and the cross bar 106 forms the center of a utensil support. Thus, a pot can be stood on the junction which, in use, is centrally located on a gas burner.
The main support 104 carries upwardly facing auxiliary cross member recesses or slots 116 , 120 each adapted to receive a further cross member. The auxiliary cross member recess includes reinforcing blocks 118 , 122 .
FIG. 2 is a side view of the trivet member of FIG. 1 . The main bar 104 has feet 108 , 110 at either end. The foot 114 of cross bar 106 is also shown. Each foot terminates in a pad such as 260 which can be rubber. FIG. 2 also shows the upwardly facing auxiliary cross member slot 116 and the reinforcing block 118 .
FIG. 3 is an end view of the trivet member of FIG. 1 . The main bar 104 is seen end on, and the cross bar 106 has feet 112 , 114 . The edges of the main bar 104 and cross bar 106 are rounded as shown at 303 , and the junction between the main bar and the cross bar are also curved as shown at 305 . FIG. 3 also shows foot 110 and pads 260 .
FIG. 4 shows a trivet member 440 according to a second embodiment of the invention having a main bar 444 and a cross bar 446 intersecting at 466 . The main bar terminates in footings 448 , 450 , and the cross bar terminates in footings 452 , 454 . The four feet make this trivet member self-supporting. The main bar includes a downwardly facing slot 456 adapted to engage an upwardly facing slot of another trivet member having an upwardly facing slot according to another embodiment of the invention, such as slots 116 , 120 of the trivet member shown in FIG. 1 . Thus the trivet element 440 can be connected to trivet element 102 by interlocking the slots 456 and slot 116 .
FIG. 5 is a section view of a footing according to an embodiment of the invention. The end of the bar 544 has a threaded projection 555 and a projecting rim 558 . The bar can be made of cast iron. The footing includes a tubular shell 550 which is preferably of stainless steel, but other suitable materials, including for example, aluminum or glass, can be used. A foot pad 260 of rubber or nylon or other suitable material is attached to the threaded projection 555 by screw 564 . A cap 566 of aluminum encloses the upper side of the foot pad 260 . Silicone sealant can be applied to the cap before insertion during assembly. FIG. 5 also shows a portion 562 of foot pad 260 which circumscribes a head of screw 564 .
FIG. 6 shows a trivet member 668 according to a further embodiment of the invention. A main member 604 terminates in footings at either end and carries three cross members 669 , 670 , 671 . This trivet member has eight feet and is self-supporting. FIG. 6 also shows an upwardly facing auxiliary cross member slot 616 and reinforcing block 618 . Each of the slot 616 and the block 618 can be similar or identical to the slot 116 and the block 118 as shown in FIG. 1 .
FIG. 7 illustrates an exploded partial view showing detail of a connection between a pair of modular trivet elements according to an embodiment of the invention. A first bar 604 has a transverse cylindrically expanded portion 618 through which a slot 616 passes. The slot 616 is mutually transverse to the axis of the cylinder and to the bar 604 . The bar also has an upper transition ending in plateau 707 . Preferably the transition is curved.
An intersecting second bar 444 has a transverse slot 456 adapted to engage with the bar 604 at the cylindrical expansion 618 . The walls 727 , 728 of the slot 456 can be curved to conform to the walls of the cylinder 618 . In the engaged state, the walls of the slot 456 overlap the walls of the cylinder 618 , and the walls of slot 616 overlap the sides of the bar 444 to stabilize the joint. The walls of the cylinder at 715 which are sectioned by the slot also provide stability against angular movement of the two modular members. The side walls of the slot 616 can provide additional stability when the bars 604 and 444 are engaged. The tolerance between the slots 616 and 456 and their mating walls are such as to enable ready assembly and stable connection while avoiding problems due to possible different thermal expansions.
In practice, the edges of the bars and slots can be rounded.
FIG. 8 illustrates schematically an assembly of two trivet members according to an embodiment of the invention. A first trivet member 668 corresponds with the trivet member 668 illustrated in FIG. 6 , and trivet member 440 corresponds to the trivet member 440 illustrated in FIG. 4 . The first trivet member 668 includes an upward facing slot at 616 , and trivet member 440 includes a downward facing slot 456 . The slots 616 and 456 are engaged by placing the trivet member 440 over the trivet member 668 so that the slots engage. This arrangement can support utensils at at least one intersection such as 456 , 466 , 874 . FIG. 8 also shows the main bar 444 and cross bar 446 of trivet member 440 . Trivet member 668 includes main bar 604 and three cross members 669 , 670 , 671 .
FIG. 9 illustrates schematically an assembly of three trivet members according to another embodiment of the invention. A first trivet member 102 , corresponding to the trivet member 102 of FIG. 1 is connected with second and third trivet members 440 A, 440 B, each corresponding to the trivet member 440 of FIG. 4 .
