DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to the annexed drawings the preferred embodiments of the present invention will be herein described for indicative purposes and by no means as of limitation.
FIG. 1 illustrates an embodiment of a portable device for windshield cleaning (10) which includes a housing (20) having a receptacle (22) and a lid (25) pivotally connected to the housing (20). The housing (20) has a handle (15) usually integral with an upper part of the housing (20). In the transport configuration (FIG. 3) the lid (25) is kept closed by a locking member (27) to hermetically seal the receptacle (22). Accordingly, as seen in FIG. 1, in use, either the lid (25) or the housing (20) has a sealing member (29) surrounding its perimeter or the opening (23) of the receptacle (22). When the locking member (27) is unlocked, the lid (25) is opened for the user to either pour some cleaning liquid (L) therein, insert a squeegee (30) therefrom, or clean the receptacle (22).
The housing (20) has a plugged discharging hole (21) for discharging used and dirty cleaning liquid (L) out from the receptacle (22). The discharging hole (21) is preferably located at the upper part (see FIG. 1) or alternatively at a lower part (see FIG. 3) of the housing (20). The lid has a handgrip (26) or the like for a user to open or close the same by pivoting it about a hinge (25′). The housing (20) is made out of any material that can provide a watertight receptacle and that is preferably transparent or translucent.
Referring to FIG. 2, the squeegee (30) has a shaft (35) which is preferably telescopic and has a conventional cleaning head (32) secured to one end (31) thereof for windshield cleaning. The other end (33) of the shaft (35) is provided with a coated handgrip (34) or the like. To protect the user holding the squeegee (30) from being sprinkled with drippings while cleaning the windshield, a disc-shaped protector (38) is radially secured to the shaft (35) by friction. The axial position of the disc-shaped protector (38) along the shaft (35) can be adjusted by simply sliding it anywhere between the handgrip (34) and the cleaning head (32), preferably in proximity to the handgrip (34) when stored in the housing (20). The disc-shaped protector (38) can easily be removed from the handgrip side of the shaft (35).
As shown in FIG. 3, a resilient circular clip (24) allows for the shaft (35) to be easily releasably secured into the housing (20) to keep the squeegee (30) in a stable position therein which is also easily reachable by the user. The secured position of the squeegee (30) inside the housing (20) also ensures that the handgrip (34) remains dry and away from the cleaning liquid (L), and the cleaning head (32) remains in immersion into the cleaning liquid (L) when in storage. It can also reduce the possible splashing around of the cleaning liquid (L) inside the housing (20) that occurs during movements of the vehicle. Preferably, the housing (20) has a generally flat bottom wall (28) to keep the device stable on any resting surface.
As is illustrated in FIG. 1, the device (10) is combined with a base (40) that is preferably and permanently secured inside the cabin of a vehicle (not shown) using any of a variety of securing means. For illustrative purpose, mounting screws (44) are shown here and adapted for releasably receiving the bottom wall (28) of the housing (20) therein and holding the same (20) in a stable upright position, especially during travelling. For the same purpose the base (40) has at least one securing element (42) to lock the housing (20) thereto. To be more versatile, the housing (20) could include at least one external holder (52) mounted on the side of the housing (20), as illustrated in FIG. 4, to releasably secure the same onto different vertical surfaces (S), such as the door of the vehicle or inside the trunk. Optionally, there could be at least one side pouch (54) connected to a wall of the housing (20) for receiving gloves (G), tools (T), and like accessories therein.
To use this portable device for windshield cleaning (10, 10a), the user opens the lid (25) (see FIG. 1), fills in the housing (20) with cleaning liquid (L) to dip the head (32) of the squeegee (30) therein, inserts the squeegee (30) via the opening (23) into the receptacle (22) of the housing (20), secures the shaft (35) using the circular clip (24), closes and hermetically locks the lid (25) with the locking member (27). The housing (20) is ready for installation either into the base (40) or the holder (52), preferably at any user accessible location for further use whenever required.
Referring to FIGS. 5 to 18, embodiments of a portable device of the present invention for window/windshield cleaning (10b, 10c, 10d, 10e) in which the housing (20b, 20c, 20d, 20e) has a handle releasably secured thereto when in transport configuration that also serves as the shaft (35b, 35c, 35d, 35e) of the squeegee (30b, 30c, 30d, 30e) when in use.
Referring more specifically to the second and third embodiments (10b, 10c) of FIGS. 5 through 8, in transport mode (FIG. 8), the lid (25b, 25c) is kept closed by the handle (35b, 35c) acting as the locking member (27) by axially slidably engaging the corresponding first and second supporting holes 27′, 27′′ of the receptacle (22b, 22c) and of the lid (25b, 25c) to preferably hermetically seal them together. The second supporting holes 27′′ are preferably screwably engaged by the threaded end (31b, 31c) of the shaft (35b, 35c) releasably secured thereto. The first supporting holes 27′ are preferably slightly larger in diameter than the second supporting holes 27′′ in order to be fitted by a tapered section of the shaft (35b, 35c) at the beginning of the handgrip (34).
Also shown in FIGS. 5 and 6, the lid (25b) includes fixed hooks (41b) protruding internally therefrom to form an in-use transporting clip (40) which serves the purpose of permitting the cleaning head (32b) of the squeegee unit (30b) to releasably engage the hooks (41b) to facilitate portability when in use (see FIG. 5).
In FIG. 6, the shaft portion of the squeegee head (32b) is shown in its storage position freely resting against a complementary recess 24′ as opposed to a resilient clip (24). Similarly, lid (25c) of the device (20c) includes fixed hooks (41c), as shown in FIG. 7. Preferably, the hooks (41b, 41c) are shaped so as to assume the contour of the cleaning head (32b, 32c) and ensure a firm engagement therebetween.
Referring to FIGS. 9 through 13, there is shown a fifth embodiment of a portable window/windshield cleaning device (10d) with a different shaped housing (20d) in transport configuration. This embodiment (10d) includes a spring-loaded, or spring-biased, in-use transporting clip (40d) internally pivotally mounted on the receptacle (22d). The transporting clip (40d) is biased by a spring (not shown) in a released position lowered against an internal side wall of the housing (20d) to permit the cleaning head (32d) easy access to the cleaning liquid (L) when required, as shown in FIG. 10. As shown in FIG. 11, the transporting clip (40d) is in squeegee engaging position with the squeegee (30d) used to carry the device (10d). Furthermore, the design of the housing (20d) is such that it allows for stacking of several units (10d) of the cleaning device in a staggered manner for convenience and economy in storage and shipping as well as efficiency and attractiveness at point-of-purchase locations in retail outlets, as illustrated in FIGS. 12 and 13.
Referring more specifically to FIGS. 14 through 18, there is shown a sixth embodiment of a portable window/windshield cleaning device (10e) similar to the embodiment (10c) of FIGS. 7 and 8 with a different lock-pin mechanism (50) for securing the first end (31e) of the shaft (35e) to the housing (20e) which allows for safe and convenient portability of the window/windshield cleaning device (10e).
FIGS. 14 and 15 more specifically show the lid-to-receptacle abutment member (42) used to maintain the lid (25e) in opened position in abutment engagement with the receptacle (22e), especially when carrying the device (10e) using the fixed hooks of the in-use transporting clip (40) secured to the lid (25e). The lid-to-receptacle abutment member (42) preferably includes a pair of lid abutting brackets (43) for abuttingly engaging a corresponding pair of receptacle abutting brackets (44) when in lid opened position.
Referring more specifically to FIGS. 16 and 17, the lock-pin mechanism (50) includes a pin (51) protruding substantially radially from the first end (31e) of the shaft (35e) adapted to lockingly engage a pin-locking recess (52) of the receptacle (22e) adjacent the second supporting hole 27′′ thereof. Accordingly, the shaft (35e) remains secured to the housing (20e) due to the resiliency of its lateral walls (46) protruding upwardly therefrom, the lateral walls (46) being engaged by the locking pin (51) and the tapered section of the shaft (35e) adjacent the handgrip (34e) itself, respectively. The pin (51) is first slidably inserted through the second supporting holes 27′′ via slots (53) thereof, as shown in FIG. 16. Then the shaft (35) is rotated either side about its axis before the pin (51) slidably engages a circumferentially oriented slope (54) extending substantially axially away from said second supporting hole 27′′ to force the shaft (35e) to squeeze in between the resilient lateral walls (46), until a partial turn is made wherein the pin (51) releasably engages the pin-locking recess (52) by snapping therein, as shown in FIG. 17.
As shown in FIG. 18, the shaft portion of the squeegee head (32e) includes a preferably partial turn slot (58) adapted to be slidably and releasably engaged by the locking pin (51). The closed end of the slot (58) includes a snapping recess (59) for resiliently and releasably securing the pin (51) therein. Obviously, the housing (20 to 20e) is made of any material that can provide a watertight receptacle.
The cleaning device (10 to 10e) of the present invention is particularly useful for use in goods transportation vehicles that usually travel over long distances in different environmental conditions.
