The present invention is directed toward electric flyswatters.
What was invented is a flexible electric flyswatter with shape memory capabilities. This invention relates generally to electric fly swatters. It is generally well known that flies within a building often land on flat surfaces, such as a wall or table, where they cannot be swatted by a traditional electric fly swatter due to their ridged outer frame and ridged grid assembly. To date, traditional electric flyswatters still follow the 1932 Renwick invention described in issued U.S. Pat. No. 1,879,495 along with the 1959 Laine invention described in issued U.S. Pat. No. 2,881,554. Both the Renwick and Laine electric flyswatters contain a ridged outer frame an exoskeleton to containing wire grids. These traditional electric flyswatters are ridged and the outer frame housing the wire grids will crack upon being struck on a hard, non-brittle surface. Furthermore, the wire grids or alternately the meshes which are a component of these flyswatters will permanently bend out of shape upon being struck on a hard, non-brittle surface. Normally, a person using an electric fly swatter either strikes the fly while in midnight while the fly is in the air or by gently placing the face of the electric fly swatter directly over the fly while it rests on a surface and then waiting until the fly travels into the grids where the fly is subsequently electrocuted. This limitation can be best illustrated by the Dynazap™ brand electric flyswatter which incorporates the Laine invention along with the Little invention; where the Little invention is described in issued U.S. Pat. No. 4,120,114. The Dynazap™ invention incorporates a preset extendable handle along with a preset swivel in its invention. It must be noted that the Renwick, Laine and Dynazap™ inventions cannot be used to strike a fly on a hard surface without causing significant damage to the electric flyswatter due to its ridged frame. It should be further noted that the Dynazap™ handle swivel arrangement must be preset and that the handle swivel on the Dynazap™ does not spring back, but rather it must be preset in a fixed place by the user before each use. Each of these inventions has limitations which have prevented them from becoming widely used.
Accordingly, it is a principal object of this invention to provide an electric fly swatter that is flexible enough in nature to strike a fly on a bard non-brittle surface.
The disclosure herein is an electric flyswatter for electrocuting a fly resting on a surface or while the fly is in flight. The term “fly” is taken to mean any flying or crawling insect, including: flies, mosquitoes, wasps, bees, ants, and spiders that are common pests. The electric flyswatter of this invention is formed of non-electrically conducting shape memory material for the frame and electrically conducting shape memory material for the rods contained within the frame.
A unique feature of this electric flyswatter is that the frame is flexible and will allow for striking on a surface without cracking or breaking. The flexibility of the frame is accomplished by utilizing shape memory polymers where there is a grooved track within the frame to encase the rods. The oppositely charged rods within the frame are comprised of electrically conducting shape memory metals which allows the rods to return back to their original shape after being deformed when striking a surface. This synergism of utilizing electrically conducting shape memory materials and non-electrically conducting shape memory materials in a flyswatter allows for the flexibility found in a traditional flyswatter combined with the benefits of electricity for killing a fly on a surface or while in the air.
Another unique feature of an alternate embodiment of this electric flyswatter is that the flexible frame is connected to the handle by a spring swivel. The spring swivel is employed to allow the frame to bend relative to the handle and to automatically return back straight relative to the handle.
An alternate embodiment of this flexible electric flyswatter invention is that two or more electrically conducting meshes of shape memory alloy are held in parallel and fastened together with non-electrically conducting connecting-spacers to allow a gap between the top mesh and the bottom meshes such that when a fly touches the top and bottom meshes the circuit will complete and the fly is subsequently electrocuted. Also included in the second embodiment is a spring-pivot-hinge fastened between the dorsal part of the handle to the proximal end of the plurality of parallel meshes. The spring swivel is employed to allow the meshes to bend relative to the handle and return back straight relative to the handle.
The electric flyswatter is constructed so that after striking a fly on a surface the rods, frame and handle will return back to their original position; or alternately, the electric flyswatter is constructed so that after striking a fly on a surface the meshes and handle will return back to their original position. The flexible electric fly swatter is constructed so that a fly is killed by electrocution and not by squashing or compressing.
Further objects and features of the present invention will be apparent, to those skilled in the art upon reference to the accompanying drawings and upon reading the following description of the preferred embodiments.

Referring to the drawings, and first to
The electric flyswatter's frame 14 with attached handle 15, are made from flexible non-electrically conducting rubber or plastic having shape memory properties. Single layer grid 12 comprising oppositely charged rods 13 are made of electrically conducting shape memory materials. Also the mesh utilized in the alternate embodiment are also made of electrically conducting shape memory materials. The shape memory materials used in the grid, rods, and/or mesh are not limited to electrically conducting shape memory alloys, but they can also be made from electrically conducting shape memory plastics as well. In an alternate embodiment a handle is connected to the frame by a spring-pivot-hinge 21 to allow the frame to bend relative to the handle and return back straight relative to the handle after deflection. Also in an alternate embodiment, a handle is connected to the meshes by a spring-pivot-hinge 21 to allow the meshes to bend relative to the handle and return back straight relative to the handle after deflection. Spring-pivot-hinge 21 is taken to mean any spring-pivot-hinge not just a double spring-pivot-hinge as shown in
It should be noted that grid 12 or alternately rods 13 will rise in temperature due to current flowing in the form of Joule heating (also known as Ohmic heating and resistive heating) when a load is placed in-between the electrically charged grids. The resulting heat caused by the load reforms the shape of the frame and the grid. In the second embodiment of this invention, the meshes also rise in temperature due to current flowing in the form of Joule heating thereby causing a deformed mesh to return back to its original shape after striking a hard surface. Also, shown in
It should be noted that the invention can be made of more than one grid. It should be further noted that the invention can be made of more than two meshes It should be also noted, that any invention comprising grids, or alternately rods, or alternately meshes, of electrically conducting shape memory materials would be within the scope of this invention.
While various changes may be made in the detail construction, it is understood that such changes will be within the spirit and scope of the present invention, as is defined by the appended claims.
This application claims the benefits of provisional patent application Ser. No. 61/797,103 filed 2012 Nov. 29 by the present inventor.
