Abstract
A scrapper for hair is based on three or more, preferably four parallel scrapper blades of rubber. The blades tend to roll hair up on a surface for ready removal and disposal.
Description
21g8404 Title: FT-~YTRT~ NULTI-BLADE SCRAPPFR FOR HAIR
AND LINT RENOVAL
Field of the Invention This invention relates to a kind of brush or scrapper for gathering lint, hair and the like from upholstery surfaces. More particularly it relates to a multi-blade scrapper having flexible scrapping blades that gather hair and lint for ready disposal.
Background to the Invention Scrappers with multiple blades are known as in United States Patent 5,212,848 which shows dual parallel "squeegee" blades for gathering water. The problem of gathering animal hair from rugs, upholstery and the like has also been addressed in United States Patent No. 4,042,995.
There is a need, however, for a brush-like scrapper that will efficiently gather hair and lint from fabrics. This is particularly so for residences having pets such as cats and dogs that tend to shed hair. The present invention addresses that need.
The invention in its general form will first be described, and then its implementation in terms of specific embodiments will be detailed with reference to the drawings following hereafter. These embodiments are intended to demonstrate the principle of the invention, and the manner of 2198~04 its implementation. The invention in its broadest and more specific forms will then be further described, and defined, in each of the individual claims which conclude this Specification.
Summary of the Invention According to one aspect of the invention a scrapper is provided with:
a) a body;
b) at least three scrapping blades mounted on said body, such blades having co-planar scrapping edges wherein said blades are made of a flexible, resilient material that will conform to a surface being scrapped to consolidate loose material on such surface for easy removal by hand.
Preferably the blades are made of rubber or a rubber-like material that will provide friction when scrapped over a fabric surface. Further, such blades are preferably aligned in parallel to each other and curved in cross-section to provide a concave face being tapered from root end to their outer edge and may be mounted so that the scrapping edge of each blade trails the location where the root is attached to the body.
As an optional feature, an opening to couple to a suction source may be provided through the handle, with 2198~04 suction passageways communicating between the opening being formed by the inter-blade regions of the scrapper.
The foregoing summarizes the principal features of the invention and some of its optional aspects. The invention may be further understood by the description of the preferred embodiments, in conjunction with the drawings, which now follow.
SummarY of the Figures Figure 1 is a perspective view of a four-bladed scrapper with a vacuum opening formed in the body of the handle;
Figure 2 is a bottom view of the scrapper of Figure l;
Figures 3, 4, 5 and 6 are perspective views of the scrapper of the invention as it is used to gather a mass of animal hair from a surface.
Description of the Preferred Embodiment In Figure 1 a body 1 provides a handle or means to grasp the scrapper 2. Extending from the body 1 are multiple scrapper blades 3 connected at their root portions 4 to the body 1. The scrapping edges of the blades 5 are co-planar and are oriented in a generally parallel alignment.
While four blades are depicted more may be employed.
The invention will also work with three blades, but not as 219~4~4 efficiently as with four or more blades. The use of four blades 3 is a convenient compromise.
Each blade 3 has a concave forward face 6, a convex rearward face 7 and has a narrowing taper from root 4 to scrapping edge 5. The narrow scrapping edge 5 contacts the hair 10 with the blade 3 being substantially vertical to the surface being scrapped (not shown) at the point of contact.
The scrapping edge 5 of each blade is preferably, though optionally positioned rearwardly of alignment with the root 4 of the blade 3. This allows a flexing action to occur that helps in gathering animal hair 10. The blades 3 are also slightly angled away from the direction of pull to counteract the tendency of the device to chatter or bounce when pulled towards the operator. In use, the narrowness of the edge 5 allows the blade 3 to flex away from the direction of pull.
The inherent tendency of the blade 3 to unflex causes it to exert greater downward and forward pressure on the hair 10 than would be likely if the blade 3 were not tapered. This downward and forward pressure causes the hair lo to remain in contact with the blade 3 as the "Hair Harvester" is pulled towards the operator.
As the device is pulled in the direction 14 towards the operator with the concave face 6 facing the operator, the inherent curvature of the blade 3 tends to straighten. This tendency to straighten is offset by the tendency to resume 2198~04 inherent curvature. The effect of this action adds an additional downward and forward pressure on the hair 10.
In Figures 1 and 2 the body 1 is shown as having a circular opening 8 passing therethrough to be fitted with the nozzle of a vacuum cleaner hose (not shown). On the lower side of the body 1, as shown in Figure 2, the opening 8 intersects the line of spaces 9 between the blades 3, that serve as inter-blade regions providing pathways for lint and hair to be sucked-up.
In Figure 3, the action of the scrapper 2 in use is shown just before it encounters hair 10. As the hair 10 is contacted by the first blade 11 it begins to roll into an elongated tangle 10A as shown in Figure 4.
Further advancement of the scrapper 2 leads to Figure 5 wherein the hair 10B is rolled past the second blade 12 into the space between the second blade 12 and third blade 13. The passage of hair 10 progressively beneath each blade 11, 12, 13 leads to it being rolled into a more dense bundle 10C as shown in Figure 6. The hair 10, by entangling within itself, becomes gathered and easily removed by hand from the surface being scrapped for disposal.
It is believed that this action arises from the flexible, hair-engaging character of, particularly, an edge of rubber material. It is unclear whether electro-static effects are involved.

2~984o ~
The body 1 of the scrapper 2 is depicted as being rectangular. Any convenient shape that supports the blades 5 and fits in a human hand will suffice.
The blades may be separately formed and attached to the body 1 as be slotting rubber strips into grooves formed in a wooden body. Or the blades 5 and body 1 may be integrally formed, as by molding the entire unit from rubber.
The "feel" of the scrapper 2 as it passes over a surface being cleaned is quite satisfying: there is a moderate drag and a sense that an effective scrapping action is being effected.
Conclusion The foregoing has constituted a description of specific embodiments showing how the invention may be applied and put into use. These embodiments are only exemplary. The invention in its broadest, and more specific aspects, is further described and defined in the claims which now follow.
These claims, and the language used therein, are to be understood in terms of the variants of the invention which have been described. They are not to be restricted to such variants, but are to be read as covering the full scope of the invention as is implicit within the invention and the disclosure that has been provided herein.
