A variety of grill lids have been invented with swivel lids.
A grill includes a main body with a main body rear right corner and a main body rear left corner. A lid cover includes a lid cover left sidewall and a lid cover right sidewall. A hinge linkage assembly connects the grill body to the grill lid. The linkage assembly includes a right front hinge link, a right rear hinge link, a left front hinge link, and a left rear hinge link. The right rear hinge link has a right rear hinge link upper joint connected to the lid cover right sidewall, and a right rear hinge link lower joint connected to the main body rear right corner. The left rear hinge link has a left rear hinge link upper joint connected to the lid cover left sidewall, and a left rear hinge link lower joint connected to the main body rear left corner.
A right side bracket is connected to the main body rear right corner, and a left side is bracket connected to the main body rear left corner. The hinge linkage assembly is connected to the right side bracket and the left side bracket. The right rear hinge link lower joint and the right front hinge link lower joint are pivotally mounted to the right side bracket. The left rear hinge link lower joint and the left front hinge link lower joint are pivotally mounted to the left side bracket.
The hinge linkage assembly is mounted to the lid cover left sidewall inside surface and the lid cover right sidewall inside surface. The right rear hinge link of the right front hinge link is mounted to the lid cover right sidewall inside surface. The left rear hinge link and the left front hinge link are mounted to the lid cover right sidewall inside surface.
A right side bracket and a left side bracket are externally mounted. The right side bracket is externally mounted to a main body right sidewall, and the left side bracket is externally mounted to a main body left sidewall. The hinge linkage assembly is externally mounted to the right side bracket and externally mounted to the left side bracket.
The left front hinge link is longer than the left rear hinge link, and the right front hinge link is longer than the right rear hinge link. A distance between the left rear hinge link upper joint and the left front hinge link upper joint is greater than a distance between the left rear hinge link lower joint and the left front hinge link lower joint. A distance between the right rear hinge link upper joint and the right front hinge link upper joint is greater than a distance between the right rear hinge link lower joint and the right front hinge link lower joint.
The following call out numbers can be a useful guide in referencing the element numbers of the drawings.
As seen in
The main body 20 is preferably formed as panels that include a front panel, a left panel, a right panel, and a rear panel. Thus, the main body has a main body right sidewall 23, and a main body left sidewall 24. The main body 20 is preferably formed of steel. Similarly, the lid cover 80 is also formed of steel and has a lid cover front sidewall 82. The front lid handle 88 is mounted to the lid cover front sidewall 82. The lid cover 80 also has a lid cover top surface 81 that is formed between a lid cover left sidewall 83 and a lid cover right sidewall 84. The lid cover 80 has a lid offset gap 87 such that it floats at a height above the main body 21 when in its closed position.
The lid cover 80 is mounted to the main body 20 at a hinge bracket 40. The hinge bracket 40 is externally mounted to the main body 20 by connectors. The hinge bracket 40 supports a hinge linkage assembly 60.
As seen in
The hinge linkage assembly 60 includes a total of four links, namely a right rear hinge link 51, a right front hinge link 53, a left front hinge link 54, and a left rear hinge link 52. A the right side bracket 41 has the right side bracket lower extension 47 that extends downwardly, and a right side bracket forward extension 55 that extends forwardly from a main body rear right corner 21. The right side bracket lower extension 57 can be connected to the main body right sidewall 23 at a right side bracket lower connector 45 and a right side rocket upper connector 43 such as by screws or rivets.
The side bracket forward extension 55 is at a main body right sidewall upper edge trim 55 of the main body right sidewall 23. The right rear hinge link 51 is mounted to the right side bracket 41 at the right rear hinge link lower joint 61 and is mounted to the lid cover right sidewall 84 at the right rear hinge link upper joint 67. The right front hinge link 53 is mounted to the right side bracket forward extension 55 at the right front hinge link lower joint 63. The right front hinge link 53 is also mounted to the lid cover right sidewall 84 at the right rear hinge link upper joint 65. The right front hinge link 53 has a right front hinge link length 92 that is longer than the right rear hinge link length 91 of the right rear hinge link 51.
The lid cover sidewall inside surfaces such as the lid cover left sidewall inside surface 85 and the lid cover right sidewall inside surface 86 receive the joint connections. The right front hinge link upper joint 65 and the right rear hinge link upper joint 67 are both mounted to the lid cover right sidewall inside surface 86 such that the right front hinge link 53 and the right rear hinge link 51 are pivotally mounted to and parallel to the lid cover right sidewall inside surface 86. The right front hinge link 53 and the right rear hinge link 51 are mounted to an external surface of the right side bracket 41. The main body right sidewall upper edge trim 25 is optionally included to be mounted to an upper edge of the main body right sidewall 23. The main body right sidewall 23 can be formed as a thick gauge steel sidewall. A the main body right sidewall upper edge trim 25 extend over an upper edge of the main body right sidewall 23 to provide structural rigidity.
As seen in
The left rear hinge link length 93 is less than the left front hinge link length 94. The left rear hinge link 52 is mounted behind the left front hinge link 54. The left rear hinge link 52 has a left rear hinge link lower joint 63 that is mounted to the left side bracket 42 near the main body rear left corner 22 and may also be connected to the main body 20 at the main body left sidewall 24. The left rear hinge link 52 has a left rear hinge link upper joint 68 that is pivotally connected to the lid cover left sidewall 83. The left front hinge link upper joint 66 is also totally connected to the lid cover left sidewall 83. The distance between the left rear hinge link upper joint 68 and the left front hinge link upper joint 66 is greater than the distance between the left rear hinge link lower joint 62 and the left front hinge link lower joint 64. This is symmetrical to the right side where the distance between the right rear hinge link upper joint 67 and the right front hinge link upper joint 65 is greater than the distance between the right rear hinge link lower joint 61 and the right front hinge link lower joint 63.
The left front hinge link upper joint 66 is mounted with the left rear hinge link upper joint on the lid cover left sidewall inside surface 85 such that the left rear hinge link 52 and the left front hinge link 54 are parallel to the lid cover left sidewall inside surface 85 and pivotally mounted to the lid cover left sidewall inside surface 85.
The lid cover front sidewall 82 can be beveled so that it rests on the cooktop tray 30. The right side bracket and the left side bracket are preferably and flat along the portion that they connect to the main body left sidewall and the main body right sidewall. Similarly, the main body left sidewall and the main body right sidewall are flat in the preferred embodiment where the grill lid is rectangular. Similarly, the hinge links are flat and fitted between the lid cover side walls and the main body sidewalls.
