- the coating material cannot be too brittle, or it will tear during the staple forming process. It is preferred that the coating material be different from the wire material.
- Nylon , or plastics containing nylon material including without limitation polyacetal, polymide, polycarbonate, polyethylene, polypropylene, polyurethane, polyvinylchloride, polyvinylidene fluoride, and blends and combinations thereof, are particular preferred for the coating. Coating with nylon provides insulation.
- the coating is of a uniform thickness of from a minimum of about 1000 mils to a maximum that will vary based on the staple leg length, the dimension of the article to be attached to the substrate, and the substrate into which the article is to be attached.
- this maximum thickness has been found to be 0.050 inches.
- a thickness of from about 0.001 inches to about 0.010 inches is preferred.
- all of the staple, or at least the portion contacting the wire or other item to be attached is coated, although the faces 57 of angled edges of each leg 51 , 52 may be devoid of coating since they are formed by cutting the wire after it is coated.

- the staple wire and coating perform different functions (e.g., the wire staple provides strength while the coating provides holding power in the substrate and has electrical insulating properties while also providing a protective barrier to prevent the wire staple material from damaging the electrical wire being stapled), the adhesion of the coating on the wire is such that the coating does not engage in substantial independent movement relative to the wire once the coating is adhered, even upon application of the fastener in the substrate. Such independent movement would adversely affect the functioning of the fastener.
- the coating can be extruded onto the wire prior to the staple-forming process.
- the coating can also be applied by spraying, dipping or other processes well known to those versed in the art of wire coating.

First, cohered cores of articles such as fasteners (e.g., insulated or coated staples) are loaded into the magazine. Staples in these cores are preferably cohered in a side-by-side relation. The tool is then aligned over the object to be fastened. Upon actuation of the driver, fasteners are expelled from the magazine, one at a time, around the object to be fastened on three sides and into the substrate. The staple pusher in the magazine assembly automatically urges the next article (e.g., coated staple) into axial alignment with the drive path to be expelled by the next complete drive stroke.

Abstract
Insulated or coated staple and a fastening tool for driving the same into a substrate. The tool includes a housing and a driver reciprocally mounted in the housing and moveable with respect to the housing, the driver having a driving surface for engaging a fastener such as a coated staple. A magazine assembly is associated with the housing for positioning and aligning the coated fastener in the path of the driver so that when actuated, the driver strikes the fastener and forcibly ejects it from the magazine into the substrate on which the object to be fastened is to be secured. Suitable fasteners include coated staples (of various sizes and configurations), nails, brads, rivets, etc.
Description
- This application is a continuation of U.S. Ser. No. 10/017,746 filed on Dec. 7, 2001, the disclosure of which is hereby incorporated by reference.
- The present invention is directed towards a coated staple and a staple gun or fastener driving or applying tool for driving such staples into surfaces.
- Staple, nail, brad, screw and other fastener-driving applying tools for industrial, commercial and do-it-yourself (DIY) use are well known. Often such tools are used to secure cables, wires, tubing and the like to a substrate such as wood by driving the fastener into the substrate, the fastener thereby surrounding the cable, wire or tubing on three sides. However, the fastener being applied may at the time of application (due to the impact of the fastener) or subsequently (due to wire and/or substrate expansion or contraction over time) penetrate, damage or deform the item being fastened, resulting in an electrical short circuit, leak or other deleterious effect.
- It is often desirable to secure wire or cable, including without limitation high speed transmission multimedia cable and wire (such as CAT-5 and RG6) and NM Building Wire (also known as “Romex” wire), to substrates using staples and so-called insulators. The use of these so-called insulators, which may also provide a cushioning function, minimizes the possibility that the staple will penetrate, damage or deform the sheathing on the wire and cause an electrical short or change in current. The use of pro-assembled individual staples and insulators, installed by means of a hammer or similar implement, is conventional. However, this method is slow, tedious, and not very precise.
- Attempts to improve the efficiency and standardization of the current process have largely focused on use of hand powered cable tacker staplers to install collated and cohered pre-assemblies of staples and so-called insulators. Each individual assembly of a staple and insulator has tended to be similar in essential form to the hammer-applied assemblies now widely employed. These attempts have proved to be inadequate and unsuccessful because they either do not install the staple/insulator assemblies in a manner which meets industry requirements for staple holding power (such as those described in UL specifications) for a wide range of wire types and diameters used in typical residential and commercial construction, or the cable tacker staplers used require too much hand pressure or too broad a range of hand motion for the average user to comfortably operate them so that they install the assemblies in accordance with such industry requirements. In addition, the quantity of staples/insulators that fit in a typically sized magazine is small, resulting in frequent reloading. This type of staple/insulator assembly is also relatively expensive.
- It is therefore an object of the present invention to provide an improved insulated or coated fastener which helps minimize or eliminate the possibility that the fastener penetrates, damages or deforms the sheathing of the wire being fastened.
- It is a further object of the present invention to provide an improved fastener driving tool or gun that ensures consistent, uniform and reproducible driving depth of the fastener into the substrate.
- It is a still further object of the present invention to provide a fastening device that automatically and repeatably drives insulated or coated fasteners to a predetermined depth into a substrate to secure an object therein.
- It is a still further object of the present invention to provide a fastener gun driven insulated or coated fastener which is relatively less expensive than those currently in use.
- It is a still further object of the present invention to provide a system of a fastening device and a more compact insulated or coated staple or fastener which requires less frequent reloading.
- The problems of the prior art have been overcome by the present invention, which provides an insulated or coated staple and a fastening tool for driving the same into a substrate. The tool includes a housing and a driver reciprocally mounted in the housing and moveable with respect to the housing, the driver having a driving surface for engaging a fastener such as a coated staple. A magazine assembly is associated with the housing for holding one or more coated fasteners, and for positioning and aligning a coated fastener in the path of the driver so that when actuated, the driver strikes the fastener and forcibly ejects it from the magazine into the substrate onto which the object to be fastened is to be secured. Suitable fasteners include coated staples (of various sizes and configurations), nails, brads, rivets, etc.

FIG. 5 is a side view of the staple ofFIG. 4 in accordance with the present invention. - Turning first to
FIG. 1 , there is shown one embodiment of the present invention, which is a spring actuated staple gun adapted to drive U-shaped staples housed in a magazine into a surface or substrate. The gun includes a tool body 1 comprised of two stamped nickel-plated sheet metal sides 1A and 1B that form a housing there between. Alternatively, the housing could be a molded body. Pivotally fixed to the underside of ahandle 2 is a spring-loaded lever assembly C, substantially located in said housing, which includes extendedlink 2A andlifter 2C and allows the handle of the gun to be cocked and uncocked in order to actuate the gun. Ahandle return spring 9 is fixed to thehandle 2.Spring retainer 8 hasopposite flanges opposite slots 5A′ 5B′ in sides 1A and 1B of the tool body 1 to fixspring retainer 8 therein. Adriver spring pad 5 aligns with the bottom of thedriver spring 6 and sits in the body ofdrive blade assembly 4.Impact pad 13 has animpact ledge 14 that aligns withopposite slots 14A and 14B in sides 1A and 1B of the tool body 1 to fix the same in the housing, and thereby limit the downward movement of driver blade assembly 4 a predetermined amount by preventing theseat 4A ofdrive blade assembly 4 from extending past the surface of theimpact pad 13. Theimpact pad 13 thus affects the location of the bottom H of the drive blade in the “rest” (down) position as it relates to the top of the tunnel in thenose piece 3, and thereby prevents the drive blade from driving the staple too tightly over the wire regardless of the wire diameter.Nose piece 3 secures over thedrive blade assembly 4 as is conventional in the art.Magazine assembly 15 combines withpusher assembly 16 to selectively provide the supply of fasteners into the path of the driver blade. - Pressing downward on the
handle 2 first causes a pair of opposite lips L, L′ oflifter 2C, which lips engage thedrive blade assembly 4, to lift thedrive blade assembly 4 upward against the bias ofdriver spring 6. Further downward pressure of thehandle 2 causes the lips L, L′ to release from thedrive blade assembly 4, thereby causing thedriver spring 6 to force thedrive blade assembly 4 downward. The downward force imparted to thedrive blade assembly 4 by thespring 6 causes the head H of the drive blade assembly to strike a staple located at the forwardmost end of themagazine assembly 15 and in the path of the drive blade, and drive the staple into the work surface below. Those skilled in the art will recognize that other ways to actuate the drive blade, including any stored energy source (such as leaf springs, torsion springs,. electricity, hydraulics and compressed gas (e.g. air)) can be used. - Turning now to
FIGS. 2 and 3 , the details of the modified drive blade are shown. The head H of thedrive blade 4 is configured to correspond in shape to the top (or crown) portion of thestaple 53, and the radiused transitional areas (shoulders) 56 which join the crown to thestaple legs drive blade 4 squarely engages the staple crown and shoulder portions and forces the staple straight out of the tool and into the substrate. Thus, the center portion of the head H is recessed slightly, with spacedopposite tips blade 4 is predetermined and depends in part on the length of the staple and the characteristics of the substrate into which the staple is being driven, so that the staple does not penetrate into the substrate too deeply. Typical substrates include standard wood building materials used in studs, joists, rafters, etc.Nose piece 3 secures over thedrive blade 4. At its sides, thenose piece 3 extends below the drive blade as shown inFIG. 3 . A U-shapednotch 30 is carved out of the bottom of thenose piece 3. Thisnotch 30 provides a receptacle and guide for the wire or other object to be fastened to be positioned relative to the staple gun. The bottom of thedrive blade 4 at rest is level with the top of thenotch 30 of thenose piece 3. This level orientation of thedrive blade 4 andnotch 30 is critical to insuring that the staple gun does not drive the fastener too deeply, thereby possibly crushing, damaging or deforming the object to be fastened. This relationship also prevents damage to the object if the staple gun is fired on a cable without staples in the magazine. This distance may vary, based on varying the thickness of the crown portion of the fastener. - Turning now to
FIGS. 4 and 5 , the insulated or coated staple of the present invention is shown. Thestaple 50 is generally U-shaped, and includes two parallel or substantially parallel vertically extendinglegs crown 53 andradiused shoulder portion 56. Thecrown portion 53 is substantially flat, withradiused shoulder areas 56 leading to theparallel legs staple leg angled cut 57, in a sharp edge (point) 55 to facilitate penetration into the substrate. Also, preferably, the angle cuts 57 to thepoints 55 are mirror images of one another (as shown). These mirror image angle cuts 57 cause the staple legs to move in opposite directions upon penetration into the substrate, making the staple more difficult to extract from the substrate, resulting in additional holding power of the staple. The degree of angle cut will vary based on the application, and will be easily determinable by one well versed in the art of staple manufacture. An angle cut of 45° has been found to be suitable for this application. - The coating for the staple 50 is made of a material that is insulating and/or cushioning and forms a strong bond with the base metal of the fastener or staple. Suitable base metals include, without limitation, bright steel and galvanized steel. The coating material cannot be too brittle, or it will tear during the staple forming process. It is preferred that the coating material be different from the wire material. Nylon , or plastics containing nylon material, including without limitation polyacetal, polymide, polycarbonate, polyethylene, polypropylene, polyurethane, polyvinylchloride, polyvinylidene fluoride, and blends and combinations thereof, are particular preferred for the coating. Coating with nylon provides insulation. It also provides, depending upon the thickness of the coating, cushioning so that upon impact of the staple with the wire or cable being fastened, the wire is even less likely to be crushed, damaged or deformed, which could cause short circuits or other deleterious effects on the electrical current being transmitted. In addition, penetration of the
staple leg staple leg faces 57 of angled edges of eachleg - The coating can be extruded onto the wire prior to the staple-forming process. The coating can also be applied by spraying, dipping or other processes well known to those versed in the art of wire coating. The base wire (e.g., galvanized steel) is made first using conventional wire drawing processes, and then the coating (e.g., nylon) is applied around the wire in a subsequent process.
- Other suitable coatings include, without limitation, dielectric materials such as thermoplastic elastomers, including polyethylene, polypropylene, polybutylene, PVC, CPVC, nylon, ABS and PVDF, with nylon being preferred.
- In view of the dimension of the coating, the staples can be accommodated by conventional staple tacker gun magazines with little or no modification thereof. Any modifications deemed necessary to accommodate the increased outer width and decreased inner width of the staple resulting from the coating are generally well within the skill of those versed in the art of staple tacker gun manufacture.
- The staple gun of the preferred embodiment of the present invention is adapted to drive U-shaped staples (releasably interconnected in the staple magazine) into a substrate in order to secure an object such as wire, cable or tubing to the substrate.
- Those skilled in the art will recognize that any stored energy source can be used to actuate the driver of the fastening tool, including, without limitation, mechanical means, compressed air, electric means, hydraulics, etc.
- In operation, the fastening tool of the preferred embodiment of the present invention is used as follows. First, cohered cores of articles such as fasteners (e.g., insulated or coated staples) are loaded into the magazine. Staples in these cores are preferably cohered in a side-by-side relation. The tool is then aligned over the object to be fastened. Upon actuation of the driver, fasteners are expelled from the magazine, one at a time, around the object to be fastened on three sides and into the substrate. The staple pusher in the magazine assembly automatically urges the next article (e.g., coated staple) into axial alignment with the drive path to be expelled by the next complete drive stroke.
