BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to a curtain assembly for a workbench, more particularly to a curtain assembly that limits scattering of sawdust around the tabletop so as to facilitate collection of sawdust.

[0003] 2. Description of the Related Art

[0004] In a woodworking factory, the huge amount of sawdust created during woodworking operations is not only detrimental to health, it can also damage the woodworking equipment and pollutes the working environment. Therefore, it has been the concern of manufacturers to develop workbenches with an air filtration capability. FIG. 1 shows such a workbench. As shown, the conventional workbench includes a base 1, a tabletop 2 on top of the base 1 and having multiple perforations 201, a filtering device 3, and a suction device (not shown). When the suction device is actuated, sawdust created during operation of the workbench is drawn into the interior of the base 1 via the perforations 201 in the tabletop 2, and the sawdust-laden air is filtered through the filtering device 3 to be discharged as sawdust-free air while the sawdust is collected in the filtering device 3. However, although some of the sawdust will be drawn into the base 1 of the workbench, some will fly around, which is a problem left unsolved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] Referring to FIGS. 2, 3 and 4, the preferred embodiment of a curtain assembly according to the present invention is adapted for use with a workbench 100. The workbench 100 includes a base member 101 and a rectangular tabletop 102 mounted on top of the base member 101. The tabletop 102 has opposite front and rear edges 110, 120 that are spaced apart in a first direction, opposite left and right edges 130, 140 that are spaced apart in a second direction transverse to the first direction, and rear left and right corner portions. Rear left and right corner brackets 150 are respectively mounted to the rear left and right corner portions of the tabletop 102. Each of the rear left and right corner brackets 150 is provided with a threaded hole 160. Furthermore, the tabletop 102 is provided with a multiplicity of perforations 170 that cooperate with a known air filtration device (not shown) and a known suction device (not shown) to collect sawdust. As the collection of sawdust is known in the art, a detailed description thereof is dispensed with herein. The curtain assembly includes left and right mounting brackets 11, rear, left and right curtain rods 12, 13, 14, and rear, left and right draperies 20A, 20B, 20C. The mounting brackets 11 are adapted to be mounted respectively on the rear left and right corner brackets 150 of the tabletop 102 so as to extend uprightly from the tabletop 102, and are spaced apart from each other in the second direction. Each of the mounting brackets 11 has a generally L-shaped cross-section, and includes an upright rear plate portion 113 that is adapted to abut against the rear edge 120 of the tabletop 102, and an upright side plate portion 115 that extends in the first direction from the upright rear plate portion 113 and that is adapted to abut against a respective one of the left and right edges 130, 140 of the tabletop 102. The rear plate portion 113 of each of the mounting brackets 11 is formed with a vertically extending slot 114. The mounting brackets 11 are adapted to be mounted adjustably on the rear left and right corner brackets 150 of the tabletop 102 so as to permit height adjustment of the rear, left and right curtain rods 12, 13, 14 relative to the tabletop 102. This will be explained in greater detail in the succeeding paragraphs.

[0015] The rear curtain rod 12 extends in the second direction, and has opposite ends mounted respectively on upper ends of the mounting brackets 11. The left and right curtain rods 13, 14 extend in the first direction. Each of the left and right curtain rods 13, 14 has a rear end mounted to the upper end of the side plate portion 115 of the respective one of the left and right mounting brackets 11 by the use of screws 131, 141. The opposite ends of the rear curtain rod 12 are mounted on the rear plate portions 113 of the mounting brackets 11 by the use of screws 121. As such, the rear, left and right curtain rods 12, 13, 14 constitute a generally U-shaped curtain mounting frame.

[0016] The rear drapery 20A has a heading portion 21A connected to the rear curtain rod 12 such that the rear drapery 20A hangs downwardly to cover a rear side of the tabletop 102. The left drapery 20B has a heading portion 21B connected to the left curtain rod 13 such that the left drapery 20B hangs downwardly to cover a left side of the tabletop 102. The right drapery 20C has a heading portion 21C connected to the right curtain rod 14 such that the right drapery 20C hangs downwardly to cover a right side of the tabletop 102. In this embodiment, each of the rear, left and right draperies 20A, 20B, 20C is made from a single piece of fabric that is folded at the upper end to form the heading portion 21A, 21B, 21C by sewing. In addition, the portion of each of the rear, left and right draperies 20A, 20B, 20C below the respective heading portion 21A, 21B, 21C is formed with a plurality of vertically extending slits 23, thereby configuring each of the rear, left and right draperies 20A, 20B, 20C with a plurality of vertically extending shade portions 22 that extend downwardly from the respective heading portion 21A, 21B, 21C. During installation, the heading portions 21A, 21B, 21C can be sleeved on the rear, left and right curtain rods 12, 13, 14, respectively, prior to mounting of the rear, left and right curtain rods 12, 13, 14 on the left and right mounting brackets 11, and screws may be used to pass through the ends of the heading portions 21A, 21B, 21C to position the latter on the rear, left and right curtain rods 12, 13, 14, respectively (see FIG. 5). As such, the rear, left and right draperies 20A, 20B, 20C cooperatively form a curtain that covers the rear, left and right sides of the tabletop 102, except the front side where the woodworker is supposed to be. The curtain assembly further includes a bridging rod 10 that extends in the second direction and that interconnects lower ends of the rear plate portions 113 of the mounting brackets 11.

[0017] In addition, the curtain assembly includes a pair of screw fasteners 16 and a pair of handles 15. Each of the screw fasteners 16 extends through the slot 114 in the rear plate portion 113 of a respective one of the mounting brackets 11, and engages the threaded hole 160 in the respective one of the brackets 150 so as to be adapted to secure the respective one of the mounting brackets 11 to the respective one of the rear left and right corner brackets 150 of the tabletop 102. The handles 15 are screwably mounted on the screw fasteners 16 to facilitate rotary driving of the screw fasteners 16. Referring to FIG. 6, when it is necessary to adjust the height of the rear, left and right curtain rods 12, 13, 14, hence the rear, left and right draperies 20A, 20B, 20C, relative to the tabletop 102, the woodworker can turn the handles 15 with both hands to thereby loosen the screw fasteners 16 slightly such that the mounting brackets 11 can slidably displace within the range of the slot 114 relative to the rear left and right corner brackets 150 of the tabletop 102 to a desirable height. After height adjustment, the handles 15 are turned to tighten the screw fasteners 16 once again. It can be seen that the height adjustment according to this invention is very easy and convenient to perform.

[0018] During woodworking operation, the sawdust created from the tabletop 102 is blocked by the rear, left and right draperies 20A, 20B, 20C, and is forced to drop onto the tabletop 102 where it is collected via a known method.

[0019] In addition, due to the arrangement of the slits 23, when a long workpiece is placed upon the tabletop 102, the workpiece can extend through the shade portions 22 without undue interference from the draperies 20A, 20B, 20C. While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
