Abstract
Multi-purpose tools are constructed of a tool head (9)(32)(53) and an extension (15)(36). A pad (16)(45)(52) can be attached to the tool head with one or more of a retainer (13), rubber bands (46)(59) and clips (60). The pad includes adhesive (24) coated sheets (22) and one or more of a seat (17), rubber bands, elastic dots (66) and a backing (18)(47)(58). Elastic elements (25)(40)(62) are attached to anchor hooks (19)(20)(41)(63) and where it is desired to bend the pad, the elastic element is stretched and connected to a desired positioning hook (14)(39)(64).
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.

DETAILED DESCRIPTION OF THE INVENTION
The numbers of the figures are not all consecutive. Alternative configurations are identified by alphabetic designators.
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.
