Abstract

A baking oven has a flame tube defining a baking chamber and a charging opening oriented in a vertical plane; a door for opening and closing the charging opening; a rail structure secured to the door and extending into the oven externally of the flame tube for providing a sliding support for the door for sliding movement in a horizontal direction towards and away from the charging opening. The door is horizontally divided into a lower door portion and an upper door portion. The upper portion is pivotally attached to the lower door portion to provide for a swinging motion of the upper door portion from an upright orientation in an arcuate vertical direction away from the charging opening.

Claims

1. In a baking oven having a flame tube defining a baking chamber and a charging opening oriented in a vertical plane;

a door for opening and closing the charging opening;

rail means secured to the door and extending into the oven externally of the flame tube for providing a sliding support for the door for sliding movement in a horizontal direction towards and away from the charging opening;

the improvement wherein said door being horizontally divided into a lower door portion and an upper door portion;

the improvement further comprising pivot means connecting said upper door portion to said lower door portion for providing for a 180°

swinging motion of said upper door portion about an axis extending along the horizontal division between a first position in which it constitutes a vertically upward continuation of said lower door portion, and a second position in which it is in a face-to-face relationship with an outer vertical surface of said lower door portion.

2. A baking oven as defined in claim 1, wherein said pivot means comprises a hinge arrangement providing for said 180°

swinging motion of said upper door portion.

3. A baking oven as defined in claim 1, further comprising locking means having a locked state for preventing pivotal movement of said upper door portion from said first position and an unlocked state permitting said pivotal movement, and release means connected to said locking means for placing said locking means from a locked state to an unlocked state.

4. A baking oven as defined in claim 3, wherein said release means is secured to said door and is manually actuatable.

5. A baking oven as defined in claim 4, wherein said upper door portion comprises a recess serving as a door handle;

the manually actuatable release means has a manually engageable operating element disposed in said recess.
