This invention relates to devices for eliminating pests and picking up small objects. More particularly, it relates to a flyswatter-type tool with a swatter, a portion of which can be bent to desired angles for reaching under or around the edges of cabinets or other out-of-the-way spots. A pad of adhesive sheets can be attached to the swatter for picking up a variety of articles or the swatter can be used, as is, for killing insects.
The prior art in the field of swatters and devices for retrieving dropped items is voluminous.
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. 884,213 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. Wade et 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 closed 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. U.S. Ser. No. 10/083,742 by R. W. Anderson also teaches a variety of devices which describe a number of tools for many of the same uses.
Tongs, at one end of a long handle, are also used for the same purpose. H. E. Baughman, U.S. Pat. No. 3,937,512, A. V. Yancy, 2,759,758, C. O. Crow, 2,469,865, and J. F. Apfel, U.S. Pat. No. 2,279,809 all teach a combination of a handle, trigger, pull rods which combine with the bar positioning handle and pincer elements to open and close pincers. J. T. McFadden, U.S. Pat. No. 3,463,244 teaches the use of a pull bar and slide fitted over the positioning bar.
Types of additional approaches are typified by j. A. McWilliams et al in U.S. Pat. No. 4,653,789. This patent teaches a device with a replaceable sticky cover on one end and a handle on the other end. The unit could be made in a telescoping model and a portion of the handle is designed to enable the user to pick up small items in hard-to-reach sites.
Finally, R. M. Jarosch, U.S. Pat. No. 6,065,787 teaches a sophisticated telescoping handle for picking up objects while standing, utilizing a pad of adhesive sheets attached to the telescoping handle.
The prior art tools are obviously robust and useful but are extremely clunky and are subject to catching on drapes, tablecloths and other objects. They would obviously look out of place in the modern home. They are too heavy, and almost useless for the wheelchair-bound, the elderly and those who operate in cramped spaces.
The tools of this invention are multi-utilitarian, are lightweight, can be used to reach under the edges of cabinets, can be elegant and do not require repetitive trigger or pulling motions. Further, they can be very lightweight which can be of great benefit in cost and convenience to those of the severely handicapped who have trouble picking up objects.
The tools of this invention have a handle, a tool head and a control rod. The tool head is made up of a tool extension base and a tool extension with a hinge line between them. The control rod is connected to the tool extension and used to position the tool extension at predetermined angles with respect to the tool extension base by interaction of the control rod with at least one of several stops positioned along the handle.
The preferred model of the invention is described in
Handle part 10 has a slot 17 through which the control rod 11 extends. Control rod 11 has, at its front end, a “T” extension 18 from which rods 19 extend laterally. The rod 19 slips under hooks 20 and is used to move tool extension 14 to a desired position. When rod 11 is moved toward the opposite end of the upper handle, part 10, e.g., to form a right angle or to form an 180° wedge.
Rod 11 is passed through slot 17 and attached to signet ring shaped positioner 13 via right angle retainers 42 (See
Flexible positioner 13 of
In
The tool head can be quite rigid but flexible across the hinge line. This rigidity can be inherent in the materials of construction and/or the design or can be obtained through the addition of springs to the tool head, for example, see the springs of
The combination of rigidity and flexibility needed to meet the differing requirements of various tool usage requires differing approaches to the design of the tools. For example, the strength requirements for the combination making up the tool head and control rod will vary with the materials used. Thus, where hinges are used at the bend line, they can be used in combination with hinge springs. Where hinges are not used and the tool extension base and tool extension are joined across the bend line, the flexibility necessary for the expected tool operation can be supplied by decreasing the thickness of the material of construction at the bend line to effect the necessary flexibility.
Where a pad with adhesive-faced sheets is to be used with the tool head, the tool head handle, rod, stop and other configuration requirements, strength, resilience and other changes, must be taken into account to ensure minimum problems over the designed life expectancy of the tool. Co-pending application Ser. No. 10/083,742 provides additional insights into the design of the handle, tool head, control rods and stops, e.g., hooks on the handle, or hook and loop fasteners.
Springs can be added to the tool head to ensure desired rigidity between the base and the extension. Where added, more flexible “rods” can be utilized, i.e., wires or chains, because the strength of the “rods” may not be needed to establish desired tool head rigidity.
This is a divisional of U.S. Ser. No. 10/248,365, filed Jan. 14, 2003 by R. J. Anderson.
