Abstract

Claims (20)

1 . A switchable grill grate assembly for a cooking grill, comprising:

a main frame configured to rest on top of a cooking grill, the main frame providing a support framework having a front side, a back side, a first end, and a second end, the support framework having a horizontal slide track extending between the first end and second end of the support framework,

a first grill grate section slidably engaged on the slide track of the main frame support framework so that the first grill grate section can slide back and forth between the first end and second end of the main frame, and

a second grill grate section adapted to rest on the slide track of the main frame next to the first grill grate section and further adapted to be lifted upwardly off of the slide track of the main frame support framework,

the second grill grate section being connected to the first grill grate section such that, when the second grill grate section is lifted upwardly off of the slide track of the main frame support framework and over the first grill grate section from one of the first or second ends of the main frame support framework toward the other of the first or second ends of the main frame support framework, the first grill grate section slides on the slide track of the main frame support framework under the second grill grate section toward the opposite first or second end of the main frame support framework previously occupied by the second grill grate section.

2 . The switchable grill grate assembly of claim 1 wherein each of the grill grate sections have substantially the same footprint.

3 . The switchable grill grate assembly of claim 1 wherein the main frame includes at least one pivot tract extending upwardly from the back side of the horizontal slide track of the main frame support framework, the first and second grill grate sections being pivotally connected to the pivot track such that rotation of the second grill grate section up and over the first grill grate section forces the first grill grate section to slide under the second grill grate section toward the position on the slide track of the main frame support framework previously occupied by the second grill grate section.

4 . The switchable grill grate assembly of claim 3 comprising two spatially separated pivot tracks extending upwardly from the back side of the horizontal slide track of the main frame support framework, the first and second grill grate sections being pivotally connected to both the spatially separated pivot tracks such that rotation of the second grill grate section up and over the first grill grate section forces the first grill grate section to slide under the second grill grate section toward the position on the slide track of the main frame support framework previously occupied by the second grill grate section.

5 . The switchable grill grate assembly of claim 4 further comprising front and back rocker arms pivotably connecting the front and back sides of the first and second grill grate sections and wherein the back rocker arms are additionally pivotably connected to the spatially separated pivot tracks extending upwardly from the back side of the horizontal slide track of the main frame support framework.

6 . The switchable grill grate assembly of claim 1 further comprising front and back front and back rocker arms pivotably connecting the front and back sides of the first and second grill grate sections.

7 . The switchable grill grate assembly of claim 1 further comprising a hand grip extending from the second grill grate section, the hand grip extending from the front side of the support framework of the main frame such that it can be gripped for rotating the second grill grate section up and over the first grill grate section.

8 . A switchable grill grate assembly for a cooking grill, comprising:

a support framework configured to rest on top of a cooking grill, the support framework having a first end and a second end, and each end of the support framework having defined corners, the support framework further having a horizontal slide track extending between the first end and second end of the support framework,

a first grill grate section slidably engaged on the slide track of the support framework so that the first grill grate section can slide back and forth between the first end and second end of the support framework, and

a second grill grate section adapted to rest on the slide track of the support framework next to the first grill grate section and further adapted to be lifted upwardly off of the slide track of the support framework,

two sets of rocker arms pivotably connecting the first grill grate section to the second grill grate section, the rocker arms maintaining a distance between the first and second grill grate sections,

guide rods pivotally connecting one set of rocker arms to the corners of the support framework opposite the set of rockers arm to which the guide rods are connected,

wherein, when the second grill grate section is lifted upwardly off of the slide track of the support framework from a position next to the first grill grate section at one end of the support framework, the following actions take place:

a) the first grill grate section slides horizontally on the slide track of the support framework toward the end of the slide track previously occupied by the second grill grate section, and

b) the second grill grate section rotates up and over the first grill grate section toward the end of the slide track previously occupied by the first grill grate section.
