CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority from U.S. Provisional Application No. 62/246,630, filed Oct. 27, 2015, the disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

The invention relates to the field of track cleaners. More particularly, the invention relates to a nozzle therefor.

BACKGROUND

Vacuum cleaners are inefficient regarding cleaning of tracks, since tracks require sweeping for cleaning them.

SUMMARY

In one aspect, the invention is directed to a track cleaner, comprising a suction nozzle for a vacuum cleaner, the suction nozzle including:

• • a body, including an inlet and an outlet;
  • a hinge disposed inside the body between the inlet and the outlet; and

DETAILED DESCRIPTION

The invention will be understood from the following detailed description of embodiments of the invention, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features are not described in detail.

The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting.

FIG. 1 is a side perspective view of a suction nozzle for a vacuum cleaner, according to one embodiment of the invention.

A suction nozzle 10 according to one embodiment of the invention, for being connected to a vacuum cleaner hose 20, includes, like any suction nozzle, an inlet 18A; an outlet 18B; a body 50 including inlet 18A and outlet 18B; and a wheeled brush 66, being rotatable about body 50.

FIG. 2 is a sectional perspective view of the suction nozzle of FIG. 1.

Rotatable brush 66 includes a hinge 12 disposed on body 50 between inlet 18A and outlet 18B; and a plurality of tangential blades 16 extend from hinge 12.

Thus, air 62 flowing from inlet 18A to outlet 18B applies pressure vertically to each blade 16, as depicted by right angle 60 between the air 62 and blades 16, and thus air 62 rotates blades 16 about hinge 12.

Referring again to FIG. 1, each of blades 16 constitutes a brush for sweeping dust 24 into body 50.

FIG. 3 is a side perspective view of a suction nozzle according to another embodiment.

According to one embodiment, many bristles 52 extend from each blade 16.

Body 50 further includes a rear wall 54.

FIG. 4 depicts the suction nozzle of FIG. 1 disposed within a track.

Suction nozzle 10 is intended for sweeping a track 22 by long blades 16 of rotatable brush 66, being inserted thereinto.

Rotatable brush 66 may further include short bristles 14, disposed at the side for sweeping the accessible regions of track 22.

FIG. 5 depicts the suction nozzle of FIG. 1 without the blades, and disposed within the track of FIG. 4.

Two side walls 76 of track 22 together with rear wall 54 form a vacuumed channel 58 from track 22 into hose 22.

Thus, referring again to the true state of FIG. 4, air 62 blown through channel 58 efficiently rotates blades 16, in addition to the efficient suction it provides for pulling dust 24.

Short bristles 14 further contribute to the forming of vacuumed channel 58, by contributing to the sealing between track 22 and body 50.

FIG. 6 is a side perspective view of a suction nozzle according to another embodiment.

FIG. 7 is a magnification of a portion of FIG. 6.

A sponge having protrusions 36 is disclosed instead of blades 16. Short wheel 38 is disclosed instead of short bristles 14.

FIG. 8 depicts the suction nozzle of FIG. 1, as an integral element of a track cleaner.

Track cleaner 80 includes a vacuum cleaner, including a suction assembly 98, hose 20, and suction nozzle 10 of FIG. 1.

FIG. 9 depicts the track cleaner of FIG. 8 disassembled.

Suction assembly 98 includes a motor 40. The water splashing assembly 42 is attached to hose 20.

FIG. 10 enlarges the suction nozzle of FIG. 9.

Suction nozzle 10 is similar to that of FIG. 1, except for being adapted to hose 20 of FIG. 9.

FIG. 11 enlarges a portion of the wheeled brush or wiper of FIG. 10.

Each blade 16 includes bristles 52 for sweeping, and a fin 92 between adjacent bristles.

FIG. 12 depicts the other side of the suction nozzle of FIG. 10.

The water is splashed from water pipe 90 of FIG. 8 to water nozzle 32.

Thus, in one aspect, the invention is directed to a track cleaner (80) including a suction nozzle (10), for a vacuum cleaner, the suction nozzle (10) including:

• • a body (50), including an inlet (18A) and an outlet (18B);
  • a hinge (12) disposed inside the body (50) between the inlet (18A) and the outlet (18B); and
  • a plurality of cleaning elements (16) extending from the hinge (12), for being tangentially rotatable in relation to the body (50),
    thereby the plurality of cleaning elements (16) receive air (62) flowing vertically (60) thereto from the inlet (18) to the outlet (18B), and function as tangential blades, thereby rotate about the hinge (12), thereby sweep.

The body (50) may further include a rear wall (54), for forming an air channel (58), for enhancing the rotation of the cleaning elements (16).

The body (50) and the cleaning elements (16) may be shaped for inserting the cleaning elements (16) into a track (22) for sweeping thereof, thereby the track (22) forms an air channel (58), for enhancing the rotation of the cleaning elements (16).

The plurality of cleaning elements (16) may include:

• • central cleaning elements (14) for sweeping within a track (22); and
  • side cleaning elements (14), being shorter than the central cleaning elements (16), for sweeping exposed regions of the track (22),
    thereby the track (22) forms an air channel (58), for enhancing the rotation of the cleaning elements (16), and the short cleaning elements (14) contribute to the forming of the vacuumed channel (58).

Each of the cleaning elements (16) may constitute: a bristle (14), a wiping brush end (36), a sponge protrusion.
