Claims

1. A downdraft table with a workpiece holder for a workpiece to be held, wherein the workpiece holder is designed stationary, wherein below and/or next to the workpiece holder, a suction device is arranged by means of which particles and/or gases can be removed downward in an exhaust flow, wherein the suction device is arranged around the workpiece holder with respect thereto and is configured to be rotatable about the workpiece holder.

2. The downdraft table according to claim 1, wherein the suction device is configured in the form of a hood and has at least one recess for a person on at least one side working at the downdraft table.

3. The downdraft table according to claim 2, wherein the suction device has at least one sidewall articulated to the top edge of the hood.

4. The downdraft table according to claim 3, wherein a plurality of sidewalls are articulated to the edge of the hood with the exception of the region of the recess.

5. The downdraft table according to claim 1, wherein a fastening device to be connected to a person by a connecting element is arranged on the hood by means of which the suction device can be rotated around the workpiece holder by the movement of the person.

6. The downdraft table according to claim 1, the suction device and/or the workpiece holder is/are designed to be adjustable in height.

7. The downdraft table according to claim 1, wherein a platform is arranged under the suction device and/or the workpiece holder on which a person can stand and can move around the workpiece holder.

8. The downdraft table according to claim 7, wherein an exhaust air line and/or a suction device is arranged in the platform that conveys the air around the workpiece holder through the suction device.

9. The downdraft table according to claim 1, wherein the suction device has a suction arm which is adjustable relative to its position with respect to the workpiece holder with an exhaust air flow guided in the interior thereof.

10. The downdraft table according to claim 1, wherein the suction device is covered at the top by means of a perforated plate, a grate or a grid.

(14) FIG. 13 shows a schematic oblique view of a downdraft table according to the invention with a worker with a first position of the suction device,

(15) FIG. 14 shows a schematic oblique view of a downdraft table according to the invention with a worker with a second position of the suction device, and

(16) FIG. 15 shows a schematic oblique view of a downdraft table according to the invention with a platform.

(17) The same reference numbers in the figures identify the same or equivalently acting elements.

(18) FIG. 1 shows an example of a downdraft table 1 with a workpiece holder 2 for a workpiece to be held.

(19) The workpiece holder 2 is designed stationary; below and next to the workpiece holder 2, a suction device 3 is arranged by means of which particles and/or gases can be removed downward in an exhaust flow.

(20) In this case, the suction device 3 is arranged around the workpiece holder 2 with respect thereto and is configured to be rotatable about the workpiece holder 2.

(21) The suction device 3 is configured in the form of a hood 4 (see FIG. 2) and has a recess 41 for a person P on one side working at the downdraft table 1.

(22) The suction device 3 has a plurality of sidewalls 5, 51 to 57 articulated to the top edge 42 of the hood 4.
