## Abstract

An oven having a cooking chamber which has a pair of opposing sidewalls and a rear wall member having a pair of end portions and a protruding portion between the end portions. First and second stationary heaters are located within lower and upper portions, respectively, of the cooking chamber and a pair of movable heaters located between the first and second stationary heaters. Each movable heater is movably attached to a corresponding one of the end portions of the rear wall member and movable between a resting position and a heating position. Each movable heater is adjacent to a corresponding sidewall when the movable heater is in the resting position. A manually operated mechanical drive system moves both movable heaters simultaneously between the resting position and the heating position. Rack support members are attached to the sidewalls for supporting a lower rack below the movable heaters and an upper rack above the movable heaters.

## Claims

### Claim 1

An oven, comprising:
a cooking chamber having a pair of opposing sidewalls, and rear wall member having a pair of end portions, the cooking chamber having an upper portion and a lower portion;
a first stationary heater located within the lower portion of the cooking chamber;
a second stationary heater located within the upper portion of the cooking chamber;
a pair of movable heaters located between the first and second stationary heaters, each movable heater being movably attached to a corresponding one of end portions of the rear wall member and movable between a resting position and a heating position, each movable heater being adjacent to a corresponding sidewall when the movable heater is in the resting position;
a manually operated mechanical drive system for moving both movable heaters simultaneously between the resting position and the heating position;
a first pair of rack support members, each rack support member being attached to a corresponding one of the opposed sidewalls so as to support a rack within the cooking chamber such that the rack is below the movable heaters; and
a second pair of rack support members, each rack support member of the second pair being attached to a corresponding one of the opposed sidewalls so as to support an additional rack within the cooking chamber such that the additional rack is above the movable heaters.

### Claim 2 (depends on 1)

The oven according to claim 1 wherein each movable heater is rotatably attached to the corresponding one of end portions of the rear wall member.

### Claim 3 (depends on 1)

The oven according to claim 1 wherein each movable heater is substantially planar.

### Claim 4 (depends on 3)

The oven according to claim 3 wherein each movable heater is substantially parallel to a corresponding sidewall when the movable heater is in the resting position.

### Claim 5 (depends on 3)

The oven according to claim 3 wherein the movable heaters are generally coplanar with each other when in the heating position.

### Claim 6 (depends on 2)

The oven according to claim 2 wherein each movable heater rotates about ninety (90) degrees when moving from the resting position to the heating position.

### Claim 7 (depends on 2)

The oven according to claim 2 wherein one movable heater rotates in a clockwise direction when moving from the resting position to the heating position, and the other movable heater rotates in a counter-clockwise direction when moving from the resting position to the heating position.

### Claim 8 (depends on 1)

The oven according to claim 1 wherein the rear wall member has a protruding portion between the end portions, the protruding portion forming part of the cooking chamber.

### Claim 9 (depends on 1)

The oven according to claim 1 wherein when racks are supported by the first and second pairs of rack support members and the movable heaters are in the heating position, the movable heaters are generally parallel to the racks.

### Claim 10

An oven, comprising:
a cooking chamber comprising a pair of opposing sidewalls, and a rear wall member, the rear wall member having a pair of end portions, each end portion being generally perpendicular to the opposing sidewalls, the cooking chamber having an upper portion and a lower portion;
a first stationary heater located within the lower portion of the cooking chamber;
a second stationary heater located within the upper portion of the cooking chamber;
a pair of movable heaters located between the first and second stationary heaters, each movable heater being movably attached to a corresponding one of the end portions of the rear wall member and movable between a resting position and a heating position, each movable heater being adjacent to a corresponding sidewall when the movable heater is in the resting position;
a manually operated mechanical drive system for moving both movable heaters simultaneously between the resting position and the heating position;
a first pair of rack support members, each rack support member being attached to a corresponding one of the opposed sidewalls so as to support a rack within the cooking chamber such that the rack is below the movable heaters; and
a second pair of rack support members, each rack support member of the second pair being attached to a corresponding one of the opposed sidewalls so as to support an additional rack within the cooking chamber such that the additional rack is above the movable heaters.

### Claim 11

An oven, comprising:
a cooking chamber comprising a pair of opposing sidewalls, and a rear wall member, the rear wall member having a pair of end portions and a protruding portion between the end portions, each end portion being generally perpendicular to the opposing sidewalls, the protruding portion forming a portion of the cooking chamber, the cooking chamber having an upper portion and a lower portion;
a first stationary heater located within the lower portion of the cooking chamber;
a second stationary heater located within the upper portion of the cooking chamber;
a pair of movable heaters located between the first and second stationary heaters, each movable heater being movably attached to a corresponding one of the end portions of the rear wall member and movable between a resting position and a heating position, each movable heater being adjacent to a corresponding sidewall when the movable heater is in the resting position;
means for moving both movable heaters simultaneously between the resting position and the heating position;
a first pair of rack support members, each rack support member being attached to a corresponding one of the opposed sidewalls so as to support a rack within the cooking chamber such that the rack is below the movable heaters; and
