SANDER DEVICE HAVING VACUUMING STRUCTURE

The present invention relates to an abrading or polishing or sander machine or sander device having a vacuuming structure for vacuuming or drawing or collecting the sand dust that may be generated by the sander device.

Typical abrading or polishing or sander machines or sander devices comprise one or more motors, one or more sander barrels or wheels or belts or members rotatably attached to a table and coupled to the motors, for being rotated or driven to sand or polish objects.

lo For example, U.S. Patent No. 6,095,906 to Wang, and U.S. Patent No. 6, 533,649 to Wang disclose two of the typical abrading machines or polishing machines or sander machines each comprising one or more sander barrels or wheels or belts or members rotatably attached to and coupled to one or more motors, for being rotated or driven by the motors.

Normally, the typical abrading machines or polishing machines or sander machines each comprises one or more working tables or platforms disposed beneath or close to the sander barrels or wheels or belts or members, for supporting the objects to be sanded or polished. While working or when grinding or sanding or polishing the objects, the generated sand dusts may be generated and may fly everywhere.

However, the typical sander machines fail to provide any vacuuming devices to vacuum or to collect the sand dusts, such that the sand dusts may fly everywhere within the working environment and may seriously pollute the lungs of the users or workers.

It is accordingly an object of the present invention to provide a sander device including a vacuuming structure for vacuuming or drawing or collecting the sand dust that may be generated by the sander device.

SUMMARY OF THE INVENTION

According to the invention there is provided a sander device comprising: a platform including an orifice formed therein, and including a chamber formed therein, and including at least one aperture formed in an outer surface thereof and communicating with the chamber o thereof, and a rotatable sander member extend through the orifice of the platform, for being driven to abrade or polish or sand objects, and to generate sand dusts. The aperture of the platform is arranged to allow the sand dusts to be drawn or vacuumed into the chamber via the aperture of the platform.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-3, an abrading or polishing or sander machine or sander device comprises a base 10 including a working table 11 for rotatably supporting one or more sander wheels or belts or members 12 which may be coupled to one or more motors, for being rotated or driven by the motors to sand or to polish various objects. A casing 13 may be attached to the working table 11, for partially shielding or covering the sander members 12.

A platform 20 includes a bracket 2l, such as attached to the 0 sides or to the bottom thereof, for attaching or securing to the working table 11 or to the base 10 with such as fasteners, latches (not shown), or the like. For example, the platform 20 may include a rod 22 extended downwardly for adjustably attaching or securing to the bracket 21 with such as a fastener 23 or the like, and for allowing the platform 20 to be adjusted up and down relative to the bracket 21 or relative to the working table 11 or to the base 10.

As shown in FIG. 4, the platform 20 includes a chamber 24 formed therein, and includes one or more apertures 25 formed in the upper or outer surface 26 and communicating with the chamber 24, for allowing air or sand dust to flow into the chamber 24 via the apertures 25 of the platform 20. The platform 20 further includes a bottom or inner surface or board 27 having an outlet port 28 (FIG. 3) for coupling to a vacuum device (not shown) via a hose 80 or the like.

A motor or a motor-driven axle 30 is disposed or attached onto the bracket 21, for indirectly or directly attached onto the working table 11 or the base 10, and may include a sander wheel or sander barrel or sander member 31 disposed thereon, and rotated in concert with the axle 30 that may be rotated or driven by a motor (not shown) via a coupling member (not shown) or the like. The device indicated by the reference number "30" may also be a motor 30 to rotate or to drive the sander member 31.

The platform 20 includes an orifice 29 (FIGS. 2-4), for receiving the axle 30 and/or the sander member 31, and for allowing the sander member 31 to extend upwardly or outwardly beyond the platform 20. The motor- driven sander member 31 may be used to lo abrade or to polish or to sand the objects, and will generate sand dusts. The sand dusts may be drawn or vacuumed into the chamber 24 via the apertures 25 of the platform 20, and then collected in a container (not shown) or the like, to prevent the sand dusts from flying everywhere within the working environment and from l 5 polluting the lungs of the users or workers.

The platform 20 may further include a peripheral recess or peripheral shoulder 32, such as located around the orifice 29 thereof, for seating or anchoring or supporting a throat plate or supporting plate 40. The plate 40 may be secured to the platform 20 with such as fasteners 33 or the like, and may include one or more holes 41 arranged for communicating with the chamber 24 of the platform 20, for allowing the air or the sand dust to also flow into the chamber 24 via the holes 41 of the plate 40, best shown in FIG. 4.

The plate 40 may further include an opening 42 aligned with the orifice 29 of the platform 20, and arranged for receiving the axle and/or the sander member 31. It is preferable that the opening 42 of the plate 40 includes a size or area or inner diameter equals to or smaller than that of the orifice 29 of the platform 20, for suitably covering or shielding the orifice 29 of the platform 20. However, the size or area or inner diameter of the opening 42 of the plate 40 may also be selectively greater than that of the orifice 29 of the platform s 20, when required.

As shown in the drawing figures, particularly in FIGS. 4-8, the sander device may include two or more plates 40 that may include different numbers of the holes 41 and that may include an opening 42 of different sizes or areas or inner diameters for adjustably lo supporting sander barrels or sander members 31 of different sizes or outer diameters. The platform 20 may further include one or more spacers or inserts or blocks 34 selectively engaged into the orifice 29, to partially fill the orifice 29 thereof, and to suitably receive the sander members 31 of different sizes or outer diameters in the orifice 29 of the platform 20. For example, the blocks 34 may include an extension 35 (FIG. 4) for selectively attaching or securing to the platform 20.

In operation, as shown in FIG. 4, when the sander member 31 is rotated or driven to abrade or to polish or to sand the objects, and thus to generate sand dusts, the sand dusts may be drawn or vacuumed into the chamber 24 via the apertures 25 of the platform and/or via the holes 41 of the plate 40, and may be collected in a container (not shown) or the like, to prevent the sand dusts from flying everywhere within the working environment and from polluting the lungs of the users or workers.
