Document Type and Number:
WIPO Patent Application WO/1998/020786
Kind Code:
A1
Abstract:
An apparatus for removing ice, frost or bugs from a glass surface includes a bottle having an outer surface and an end. The apparatus also includes a base attached to the end of the bottle and washer interposed between the bottle and the base. The apparatus further includes a guard extending from the washer so as to define a space interposed between the bottle and the guard. In addition, the apparatus includes a plurality of gripping members extending outwardly from the outer surface of the bottle. The gripping members increase the ergonomic efficiency of the apparatus. The base of the apparatus has flutes extending therefrom for the removal of ice or frost from a glass surface. Alternatively, the base can have a fabric attached thereto for the removal of bugs from a glass surface.

Description:
ERGONOMICAL HAND-HELD SCRAPER AND ICE REMOVAL DEVICE FOR WINDOW-GLASS CLEANING SYSTEM BRIEF DESCRIPTION OF THE INVENTION: This invention involves ergonomically efficient, hand- held frost cutter and ice breaker assemblies. The frost cutter assembly incorporates a comfort (filler) washer between its upper bottle portion and its lower frost cutter portion. The ice scraper assembly has a finger protector guard between its bottle and ice breaker portion. Both the comfort washer and finger protector are interchangeable and have open space for assembling their respective structures.

The bottle top has structures/protrusions or recessed, curved, concave surfaces with adjacent beveled surfaces, which are raised compared to said adjacent, curved concave surfaces, to aid in gripping same and lessening the force required to be exerted by the user, thus increasing the ergonomic efficiency of the devices. These devices can be fitted with bug remover fabric mesh associated with a foam backer and fitted onto"0"ring recesses using rubber"0" rings. The bottles can have a top, flat surface containing a logo or advertising placed thereon. Preferably the bottle portion can be clear plastic, viz., substantially transparent.

These devices are small and can be easily stored.

DETAILED DESCRIPTION OF THE INVENTION: As can be seen from the isometric views of Figures 5 and 6, Figure 5 shows the bottle, comfort (filler) washer, and frost scraper assembly (10). Figure 6 illustrates the bottle, finger protector guard and ice breaker assembly (10'). The comfort (filler) washer (11) is shown in Figure 1. Figure 2 shows finger protector guard (11').

The cross-sectional view of the comfort (filler) washer (12) is shown in Figure 3 having its beveled inner surface (13) and curved outer surface (14).

Figure 4 of the drawings shows finger protector guard (12') having its beveled inner surface (13) and curved outer surface (14). Both the comfort (filler) washer and finger protector guard have open space (15) for assembling their respective structures Figures 1, 2,5 & 6. Frost cutter solution containment base (35) has its lower solid portion (16) as shown in Figure 5. Correspondingly, ice breaker solution containment base (36) has its lower solid portion (16)'as shown, for example, in Figure 6. Figures 5 & 6 each show a bottle (17) with a bottle top flat surface (19) having

placed thereon a logo (18). This arrangement is shown in Figures 5 through 8. Figure 9 shows the bottom surface (20) of the frost cutter base and Figure 10 shows the bottom surface (20') of the ice breaker base.

The scraper base flutes can be seen in cross-section from lines 11-11 of Figure 9 whereas the ice breaker flutes can be seen from section lines 12-12 of Figure 10.

Figure 11 shows the frost cutting scraper flutes (22) as composed of scraper flutes base (23) and scraper flutes triangular extended portions (24) as shown from Figure 11.

This semi-flexible frost cutter accommodates glass surfaces, whether concave or convex. For example, the semi-flexible frost cutter can be used on the concave windshields on the outside and also on the convex surface windshields on the inside. These flutes can be made of semi-flexible polyethylene or equivalent plastic material.

The ice breaker round, semi-circular, convex, extended portions (24') can be made of hard polyethylene or equivalent plastic material. They are shown in Figure 12 as having their lower base portions (23') and convex, semi-circular extended portions (24').

Frost cutting flutes (22) (sectioned) can be seen in Figure 11 whereas ice breaker flutes (24') can be shown sectioned in Figure 12. The scraper flute base (23) and the ice breaker flutes base (23') are shown, respectively, in Figures 11 and 12.

As will be noted from Figure 11 the semi-flexible frost cutter has scraper flutes which are triangular extended portions to accommodate glass surfaces, whether concave or convex. Thus they can be used on the concave windshields on the outside as well as on the convex surface windshields on the inside. The round, semi-circular, ice breaker flutes have extended portions (24') extending from their respective bases (23').

The bottles of both the frost cutter and the ice breaker assemblies can, and usually do, contain a solution to aid in dissolving road film on the inside and/or outside of the window. These bottle assemblies have a lower bottle portion (25) having a flared rim (27) and downwardly beveled sections (28) located beneath the respective flared rims (27) of each lower bottle portion. As will be noted from Figures 15 and 16, the downward bevel of each bottle lower portion is below its flared rim (27). Beneath each respective beveled portion (28) there are male threads (26) which are substantially parallel, yet slanted. This structure is apparent from Figures 13 through 16.

The outer surfaces of the bottle portions above flared rim (27) have exterior portions which aid in gripping said bottle portions. Thus Figure 15 illustrates convex, semi- circular protrusions (29) for this purpose and the structure of Figure 16 illustrates the use of recessed, curved, concave surfaces and adjacent, beveled surfaces, which are raised compared to said adjacent, curved, concave surfaces, as shown at (30) to likewise aid gripping same and lessening the force required to be exerted by the user, thus increasing the ergonomic efficiency of the devices.

The devices of this invention can be fitted with bug remover fabric mesh, as is shown in Figure 17. Such bug remover fabric mesh can have an inner portion (31) and an outer portion (32) as shown in Figure 17. This bug remover fabric mesh can be fitted on to"O"ring recesses (33) such as are shown in Figures 5,6,7,8,13 & 14. The"O"rings, themselves, (34) can be made of rubber, or equivalent material.

Figure 17 shows the bug remover fabric covering composed of inner fabric mesh portion (31) and outer fabric mesh portion (32) which are wrapped around rubber"0"ring (34) and foam backer (37) to be fitted onto the lower portion of the frost cutter and/or the ice breaker by placement of the

rubber"O"ring (34) within its appropriate"0"ring recess (33).

Shade lines 38 are shown in Figures 15,16 & 17.

In accordance with a preferred embodiment of this invention, the bottle portion of the assembly can be clear plastic, viz., substantially transparent. Thus this invention provides ergonomically efficient, hand-held frost cutter and ice breaker assemblies. The frost cutter assembly incorporates a comfort (filler) washer between its upper bottle portion and its lower frost cutter portion. The ice scraper assembly has a finger protector guard between its bottle and ice breaker portion. Both the comfort washer and finger protector are interchangeable and have open space for assembling their respective structures. The bottle top has structures (protrusions or recessed, curved, concave surfaces with adjacent beveled surfaces) which are raised compared to said adjacent, curved concave surfaces, to aid in gripping same and lessening the force required to be exerted by the user, thus increasing the ergonomic efficiency of the devices. These devices can be fitted with bug remover fabric mesh associated with a foam backer and fitted onto"0"ring recesses using rubber"0"rings. The bottles can have a top, flat surface containing a logo or advertising placed thereon.

Preferably the bottle portion can be clear plastic, viz., substantially transparent.

These devices are small and can be easily stored.
