Description




BACKGROUND OF THE INVENTION




This invention relates to multi-purpose tools that can be configured to have surfaces ranging from flat to wedge shaped and are used, for example, as fly swatters and as retrievers of objects in difficult-to-reach locations.




It is particularly useful to those who can't bend easily, e.g., a wheelchair-bound individual.




Well-known insect swatters of the past include a variety of designs based on the use of screen wire, e.g., U.S. Pat. No. 537,660 to F. W. Wood and U.S. Pat. No. 1,237,081 to J. L. Mott, Jr. Other perforated swatters use holes, e.g., U.S. Des. Pat. No. 401,304 to Kate L. Hawkins and slots, e.g., U.S. Pat. No. 2,736,129 to N. W. Roop. Since users break the handles or wear out the swatter head, a variety of mechanisms have been created to make repairs. The creativity utilized is depicted in exemplary U.S. Pat. No. 884,216 to F. M. Schmidt, U.S. Pat. No. 2,736,129 cited above; U.S. Pat. No. 2,963,816 to M. E. DeMiller and U.S. Pat. No. 4,905,408 to C. R. Wu et al and U.S. Pat. No. 5,630,290 to B. R. Wadeet al.




Another approach to the disposition of small insects and animals includes the use of adhesives, especially where the kill or capture is to be on a ceiling or on the floor adjacent a wall. Typical swatters are shown in a variety of U.S. Patents: U.S. Pat. No. 4,653,222 to T. N. Viscosi teaches a typical swatter configuration except that a pad and adhesive papers is seated within swatter head having a rim around the edges at a height which allows the top adhesive sheet to hit the insect, but not the surface on which the insect is resting.




U.S. Pat. No. 5,634,293 to A. V. Mike et al teach a swatter with a slit. A folded member having adhesive on the external folded surface is inserted through the slot with the center of the fold extending to the rear and then opened across the front of the swatter to expose the adhesive-clad inner surfaces. When a pest is adhered, the inner surfaces are again dosed for disposal of the entombed pest




U.S. Pat. No. 6,055,767 to T. D. Carter teaches a one-piece handle/swatter combination with a pad of sheets having the form of the swatter where the pads are made up of sheets with an adhesive on each side for quick adhesion to the swatter.




SUMMARY OF THE INVENTION




The tools of this invention have a handle and/or a fixture which can be attached to a handle extension or another tool and which enlarges into a tool head. The tool head includes at least one mechanism for attaching a pad of adhesive coated sheets, a pad supporting extension and elastic and hook elements for bending the pad to predetermined shapes.

FIG. 1

shows a tool


10


which has a telescoping handle with sections


11


and a hand grip


12


. The handle


11


enlarges into a tool head which includes a fixed retainer


13


on the upper side, as viewed, and a series of positioning hooks


14


and a short extension


15


on the lower side. A pad


16


is positioned by a seat


17


which is made up of a folded-over section of the backing


18


adhered to the adjacent portion of the backing


18


.




The diagrammatic cutaway pad


16


of

FIG. 2

shows a detailed section of the “right” end of backing


18


, with a lateral anchor hook


19


and centered elastic element anchor hook


20


(

FIG. 3

) at the opposite end. Two exemplary sheets


22


are affixed to backing


18


and each other by a releasable adhesive layers


23


. Backing


18


is stiff enough to allow the tool to be used as a swatter, flexible enough to curl around the end of extension


15


and resilient enough to return substantially to its original shape (see FIGS.


5


and


6


). Sheets


22


also have, on their lower side as shown, a sheet-to-sheet adhesive


23


and on their upper side, a layer


24


of an adhesive selected to adhere to the items to be retrieved.





FIG. 3

depicts a pad


16


with a seat


17


and a backing


18


. At the upper end of backing


18


are lateral anchor hooks


19


and a central anchor hook


20


. Slots


21


provide an airflow to enhance the movement of tool


10


through the air. The pad also has two single sheets


22


covered by an adhesive layer


24


. A rubber band


25


is shown positioned within anchor hooks


19


and


20


.




The upper end of cutaway handle


10


of

FIG. 4

includes a retainer


13


and extension


15


. The inner lateral edges


26


of retainer and the corresponding portion


27


of extension


15


are tapered inwardly so that the seat


17


of pad


16


(

FIG. 3

) can be inserted into and retained within a cavity


28


. The use of a grid


29


, which aligns efficiently with slots


21


(

FIG. 3

) provides desired air flow. The retainer


13


can extend upwardly to project over the lower edge of the sheets when pulled up by pad


16


during the bending process.





FIGS. 5 and 6

each outline the upper portion of a tool


10


having a pad


16


with one thick sheet


22


attached to pad backing


18


, and bent, respectively, into a right angle over short extension


15


at substantially a 90° and 180° positions.




The views of

FIGS. 7 and 8

depict a second illustrative model tool head


32


designed for the primary use as an insect and small animal swatter. Tool head


32


has a replaceable handle


33


with a tongue (not shown) which seats in a socket (not shown) in the tool head base


30


. Any practical locking mechanism can be utilized, e.g., that of U.S. Pat. No. 2,736,129 to N. W. Roop. The tool head frame


36


has front facing ridges


37


and a rear facing illustrative series of grooves


38


which permit frame


36


to be bent at various angles up to a wedge shape. At the top of frame


36


is a number of positioning hooks


39


for attachment by an elastic element


40


. At the lower rear of frame


36


is a “T” shaped anchoring hook


41


or a circle of hooks around which elastic element


40


rests when not in use. The elastic element


40


is kept in place by a camming member


42


. Camming member


42


is held in place by a screw


43


. Gaps


44


provide spaces for the placement of the elastic bands


46


of the pad


45


of FIG.


9


.




To obtain a bend in frame


36


of increasing degrees of angle, elastic element


40


is placed within spaced apart positioning hooks


39


. Where it is desirable to have a rounded pad face, the elastic element


40


is placed around one or more positioning hooks


39


on opposite ends of the pad. Similarly, the pad face can be curved by attaching the elastic element


40


on only one side of the pad.




In

FIG. 9

, the rear view of pad


45


shows two elastic bands


46


attached to the pad backing


47


to which a thick adhesive coated sheet


48


is attached. Two well attached spring metal or plastic spring strips


49


are attached to pad backing


47


to ensure a full return (verticalizaton) of the pad


45


after bends.




The model of

FIGS. 10-12

has a handle


50


with an enlarged end


51


which pivots around a rivet, screw or bolt


52


(FIG.


12


). The rivet, screw or bolt


52


allows rotation of tool head


53


. A Phillips-head screw or other locking mechanism


54


is shown placed in the center of five holes


55


to fix the angle of the tool head


53


with respect to the handle


50


. An outlined pad


56


, including adhesive-coated sheets


57


(FIG.


11


), is removably affixed to a backing


58


which is attached to the tool head


53


through the use of one or more elastic bands


59


. The elastic band


59


slips over tool head


53


when the pad


56


is put into place and is positioned by clips


60


which clip onto the pad backing


58


at a point below (See Figured


11


) the ends of the adhesive-coated sheets


57


. A pair of opposed grooves


61


in backing


58


facilitate the bending of the tool head


53


through the use of an elastic element


62


(FIG.


12


). The elastic element


62


is attached via anchor hooks


63


and used to bend tool head


53


by affixing the elastic element


62


within one of the lower positioning hooks


64


(See

FIGS. 11 and 12

) rather than the upper positioning hook


64


which is used when the tool is intended for use as a swatter.




A scraper edge


65


is shown at the upper edge of tool head


53


. Dots


66


(

FIG. 10

) are of a highly elastic, highly resilient rubber or resin and link the rear of one sheet


57


to the front of an adjacent sheet


57


and stretch to prevent the sheets from fanning out when the tool head


63


is bent.





FIG. 13

depicts verticalization springs


67


extending from the “upper” edge of an extension


15


of the unit of FIG.


4


. This configuration eliminates any need for the springs


49


used in the model pad


45


of FIG.


9


.




GENERAL TEACHING OF THE INVENTION




The variety of models depicted suggest still further models. Thus, the extendable handles of

FIG. 1

are not limited to the types used in small households and low-ceilinged offices. For example, the handles can be adapted to be screwed onto or otherwise connected to any of the extension “poles” used today, for example, by house painters and others.




As indicated by the Figures, a variety of pad shapes and degrees of open spaces can be utilized within the pad. The pad backing extensions can be of any practical length. Similarly, the mechanisms for attaching the pads are shown ranging from releasable adhesives, to retainers forming enclosures for a seat on the bottom of the pad, to rubber bands and clamps. While only a single retainer unit is shown, retainers and/or clips can be positioned at both the top and bottom of a full extension to position pads with double seats. The “tool head”-to-handle angle can also be varied. Thus, the pad can be bent or curved vertically or laterally through the use of one or more elastic element and hook configurations of ways. A variety of mechanisms are known for rotating elements such as the tool head vis a vis the handle in addition to the examples provided in the Figures.




Generally, the pad backing will be constructed of a resilient, paper product, plastic or metal. It may be that, however, the backing is no more than a curved adhesive layer used in binding books on pads or a uniform adhesive layer similar to the partial adhesive layer


23


of FIG.


2


. The pad backing can also be a composite structure with stiff upper and lower portions connected to flexible materials inserted at desired points, usually at the center line. Further, where the backing is not resilient, metallic or plastic, springs can be used to provide the desired resiliency, either by attachment to the pad backing, the pad holder backing or to an extension.




The “adhesive” coatings can be selected for particular uses, e.g., polar adhesives can be made of polar molecules in adhesive layer


24


, for example, utilized for most insects, small animals and industrial waste particulates. The “adhesives” can also be minimally or non-adhesive but have sufficient depth to enable enough pressure to be applied to “stick” glass shards, metal filings and other sharp objects into the coating as well as to adhere to it. In a proper setting, adhesives can be omitted, e.g., hooks from “hook and loop” fasteners can be the adhesive of choice, e.g., for picking up some types of materials.




The elastic element can normally be in the form of a “rubber band” but can also be a coiled spring circlet of predetermined elasticity, strength and size. The elastic elements can be continuous or an elastic piece joined at the ends by a crimped metal fastener or the like. Alternately, the elastic element can have hooks, holes or enlargements which can be fitted into complementary hooks, projections, etc.
