Closure door arrangement for a roasting, baking or cooking machine y ·.

'■ The innovation relates to a closure

Door arrangement for a roasting, baking or cooking machine, whereby the ·· ; the door can be raised and lowered via chain or rope drives arranged on both sides.

DAS 2 100 318 shows a door of this type, with two approaches attached on both sides of the side edges of the door, z. B. are welded * with which the two ends of a chain drive or the cable drive are releasably connected by means of screws and the like. The disadvantage is that in the event of a malfunction or in the case of cleaning the door, the screws must first be loosened with the result that the chains of this

Roll back the chain drive over the guide rollers and the like and thus detach themselves from the guide. When reinserting the door the chains must first be hooked in again and screwed to the shoulders of the door. This is extremely cumbersome and also time consuming.

The object of the innovation is therefore to improve this prior art lock door so that a simple one and also easy removal is ensured and that about it In addition, there is also no risk of the chains loosening from the guide rollers and the like.

This object is achieved according to the invention in that the two rope or chain ends of each drive on a common Bar are hinged, and that on each parallel to the direction of movement of the door side of the door at least e i η e tab is attached, which is releasably connected to the associated bar.

According to a preferred embodiment, each tab has a mouth-like recess, which in the locking position engages over a pin connected to the bar. There is a locking pin on each tab attached, which is in the locked position in a key

Due to the design according to the innovation, hanging and loosening the locking door is extremely easy. For this it is sufficient lifting the door a little and moving it forwards if the door is to be released. When making the connection the door is done in reverse order.

A securing device is advantageous for preventing unintentional loosening of the locking pin and the Bar provided. This ensures that the door cannot be accidentally released.

According to a preferred embodiment, the securing device has a bar with each locking pin associated keyhole-shaped slot, and in the locking position the thickening of the associated locking pin engages behind the narrower part of the keyhole-shaped Slot.

The bar of the securing device can expediently be releasably connected to the bar by means of screws.

The door is advantageously provided with retractable bow handles.

Two embodiments of the innovation according to the lock door are illustrated in more detail below with reference to the drawing. In this show in a purely schematic way:

Fig. 1 is a front view of the locking door according to FIG Innovation,

Fig. 2 is a partial view on an enlarged scale

first embodiment of the lock door according to the innovation,

FIG. 3 is a partial side view of the arrangement according to FIG. 2

Fig. 4 is a partial side view of a second embodiment form of the lock door according to the invention,

FIG. 5 shows a horizontal section along the line V-V in FIG. 2.

With 1 (Fig. 1) the lock door is referred to, which can be raised and lowered via chain drives arranged on both sides. In the open position, the door 1 is shown with a dashed line train shown.

• The two chain drives essentially consist of the! Chains 2 with the two chain ends 2a, 2b and the pulleys \ 3, 4. The drive of the two chain drives is only indicated, since it is of subordinate importance for the innovation. Instead of the chain drive, a cable drive and the like can of course also be provided.

In the embodiment shown, on each door side lying parallel to the direction of movement of the door 1 each a tab 5 or 5a attached, which with a bar is releasably connectable. The two ends 2a, 2b of the chains 2 are hinged to this bar 6

In the embodiment according to FIG. 5, each tab 5a has a mouth-like recess 7 which, in the locking position, engages over a pin connected to the bar 6. By simply lifting and moving forward de shutter door 1 can be released from the strip 6 and be connected to it again.

In the embodiment according to FIGS. 1 to 3, however, there is a locking pin in each bar 6 9 attached, which engages in a keyhole-shaped slot 10 in the locking position. The free end of the locking pin 9 has a thickening 9a.

gelungs zap fens 9 from the bar 6 referred to. This safety device In the embodiment shown, 11 consists of a bar with each locking pin 9 associated keyhole-shaped slot 11a, the thickening 9a of the associated locking pin in the locking position 9 overlaps the narrow part of the keyhole-shaped slot 11a. By lifting the safety device 11 and releasing the thickening 9a from the keyhole-shaped recesses 11a, the securing device 11 is shown in FIG the release position transferred.

The securing device 11 can expediently be releasably connected to the strip 6 by means of screws 12 and the like.

For better handling, the locking door 1 is with retractable bow handles 13 are provided.

A device 14 is advantageously provided with which the seal 15 of the locking door 1 in the closed position against the corresponding wall 16 of the roasting, baking or cooking machine can be pressed (Fig. 4). In the embodiment shown, the device 14 consists of a tension bracket, which by means of a pulling device is automatically operated and the locking door 1 - as soon as it is closed - in the direction of the arrow pulls against the wall 16, the seal 15 ensuring a complete door closure.
