Grill device having a space adjusting unit to adjust a space between an upper grill unit and a lower grill unit

A grill device comprising:

• a horizontal lower grill unit having a rear side and provided with a lower cooking member;
• a U-shaped frame pivoted to said rear side of said lower grill unit about a pivot axis such that said frame is turnable about the pivot axis toward and away from said lower grill unit, said frame having two parallel lateral arms defining therebetween a receiving space;
• a pair of first pivots;
• a horizontal upper grill unit disposed in said receiving space and pivoted to said lateral arms of said frame via said first pivots, which extend in a direction parallel to the pivot axis, so as to be turnable relative to said frame, said upper grill unit having an upper cooking member that cooperates with said lower cooking member to define a cooking space therebetween;
• and
• a space adjusting unit including
• second, third and fourth pivots,
• pivotally connected first and second links, said first link being pivoted to said upper grill unit via said second pivot, which is disposed frontwardly of and which extends in a direction parallel to said first pivots, said second link being pivoted to said first link and one of said lateral arms via said third and fourth pivots, respectively, which extend in directions parallel to said first pivots, and
• a positioning member for positioning said lateral arms of said frame relative to said lower grill unit at an acute angle, thereby spacing said upper cooking member apart from said lower cooking member.
