Description




BACKGROUND




1. Field of Invention




The present invention generally relates to a nail holder strip. More particularly, the present invention relates to a strip of fasteners, such as nails, pins, or other fastening devices.




2. State of the Art




There are many fastener-driving tools available on the market at present. Many of these tools are designed to utilize strips of collated fasteners, such as nails, pins and staples. Various forms of driving tools exist, such as manually, electrically, pneumatically, and combustion actuated. Typically, fasteners are designed to be driven into a workpiece or through a workpiece into a substrate.




In order to be effective, each strip includes a plurality of fasteners releasably attached to one another. Some fastener strips include molded plastic carriers, with each carrier independently attached to each individual fastener, while releasably engaged to one another. Generally each carrier is attached to another such carrier via a frangible bridge, which is broken as the fastener is driven into the workpiece. In many instances, the carrier remains attached to the fastener to act as a bushing. One of the drawbacks of this type of system is the possibility of buckling of the strip during use. To overcome this defect, the prior art has generally utilized an excessive amount of material to ensure rigidity. Increase in materials generally leads to increase in the expense of manufacture, and thereby the cost of the product. Accordingly, there is a recognized need for a more effective nail holder strip that is easy to manufacture, use, store, and at the same time economical.




OBJECTS AND SUMMARY OF THE INVENTION




Accordingly, it is an object of the present invention to provide a nail holder strip.




Another object of the present invention is to provide a nail holder strip that utilizes less material than those found on the market at present.




It is a further object of the present invention to provide a nail holder strip that is economical and easy to manufacture.




These and other objects of the present invention will be apparent in the following description.




The present invention provides a nail holder strip, having a plurality of nail holders including a support base for holding and supporting a nail, and a passage in the support base for receiving the nail. Additionally, the nail holder strip may include a stiffening stem positioned adjacent to the passage and to the support base, so as to provide additional rigidity of the strip.




In another embodiment, the present invention provides a nail holder strip, having a plurality of nail holders including a support base for holding and supporting a nail, and a passage in the support base for receiving the nail. The nail holder strip may also include a stiffening stem positioned adjacent to the passage and to the support base, so as to provide additional rigidity to the strip. A protrusion may be included within the passage so as to provide a releasable frictional hold on the nail. Additionally, the protrusion may be positioned in an opposite position in relation to the protrusion within the passage in an adjacent nail holder of the plurality of nail holders forming the nail holder strip.




In another embodiment, the present invention provides a nail holder strip, having a plurality of nail holders including a support base for holding and supporting a nail, and a passage in the support base for receiving the nail. The nail holder strip may also include a plurality of stiffening stems positioned adjacent to the passage and to the support base, so as to provide additional rigidity to the strip. In order to reinforce or stabilize the plurality of stiffening stems a single brace or a plurality of braces may be provided adjacent to the support base and at least one of the plurality of stiffening stems.

DETAILED DESCRIPTION




With reference now to the figures and, in particular, with reference to

FIGS. 1



a


-


3


, there is depicted a representation of a nail holder strip


10


of the present invention. The nail holder strip includes a plurality of nail holders


12


(FIGS.


4


and


5


), which are releasably attached to one another, as shown in

FIGS. 1



a


and


2


. The nail holders are releasably attached to one another by two bridges


50


, one between adjacent base supports


20


and another between adjacent stiffening stems


30


(described below). However, it would be readily apparent to one of ordinary skill in the art, that the releasable attachment may be accomplished by other means, such as, but not limited to, a single bridge, more than two bridges, or by any other releasable attachment mechanism.




A passage


40


is provided in each nail holder for receiving a nail. However, it would be readily apparent to one of ordinary skill in the art, that the nail may be substituted by other fasteners, such as, but not limited to, pins, tacks, or staples. The passage is further provided with a protrusion


46


that extends into the passage and abuts the nail. The nail stem is held in frictional engagement within the passage, but with enough of the circumferential area of the stem remaining free from contact with the nail holder to allow for the nail to effectively slide within the passage during application. As the present invention utilized approximately 40% less material than the prior art, there is a greater risk of the strip bowing or buckling during use. In order to overcome this drawback the prior art utilizes more material to make the strip stiff, while the present invention, on the other hand, utilizes the protrusions in the passage. As shown in

FIG. 1



a,


the protrusion may be positioned in an alternating arrangement, which helps to balance the strip as it is fed through the fastener-driving tool, and thereby avoid jamming.




In addition to the protrusion, the passage may further include two portions with different relative diameters, as shown in

FIGS. 2 and 5

. A first portion


42


including the protrusion


46


extends for most of the length of the passage and is provided for frictionally engaging the nail, as described above. A second portion


44


is provided at a position nearest to the head of the nail.




Stiffening stems


30


are provided and positioned along the length of the nail for additional rigidity of the strip. The stiffening stems help to stabilize and align the strip, keeping it rigid and balanced as it is fed through the tool, and thereby aids in avoiding jamming of the tool. In order to provide for further rigidity and support, braces


60


are positioned (

FIGS. 1



a,




2


,


3


,


4


) along the base of the stiffening stems and the top of the support base. The braces help to rigidly hold the stiffening stems in position to better stabilize and align the strip.




In operation the nail holder strip


10


is fed through a fastener-driving tool. As each individual nail is driven into the workpiece, the respective nail holder


12


is separated from the rest of the strip, as the force of the impact breaks the bridges


50


that connect the nail holder to the rest of the strip. Additionally, the impact of the nail as it is driven into the workpiece forces the head into the support base


20


, which acts as a bushing.




While the foregoing has described and exemplified aspects of various embodiments of the present invention, those skilled in the art will recognize that alternative elements and techniques, and/or combinations and sub-combinations of the described elements and techniques, can be substituted for, or added to, the embodiments and methods described herein. The present invention, therefore, should not be limited to, or defined by, the specific apparatus, methods, and articles-of-manufacture described herein, but rather by the appended claims, which are intended to be construed in accordance with well-settled principles of claim construction, including, but not limited to, the following:




Limitations should not be read from the specification or drawings into the claims (e.g., if the claim calls for a “chair,” and the specification and drawings show a rocking chair, the claim term “chair” should not be limited to a rocking chair, but rather should be construed to cover any type of “chair”).




The words “comprising,” “including,” and “having” are always open-ended, irrespective of whether they appear as the primary transitional phrase of a claim, or as a transitional phrase within an element or sub-element of the claim (e.g., the claim “a widget comprising: A; B; and C” would be infringed by a device containing 2A's, B, and 3C's; also, the claim “a gizmo comprising: A; B, including X, Y, and Z; and C, having P and Q” would be infringed by a device containing 3A's, 2X's, 3Y's, Z, 6P's, and Q).




The indefinite articles “a” or “an” mean “one or more”; where, instead, a purely singular meaning is intended, a phrase such as “one,” “only one,” or “a single,” will appear.




Where the phrase “means for” precedes a function, it is intended that the resulting means-plus-function element be construed to cover any, and all, implementations of the recited function using any standard techniques known by, or available to, persons skilled in the relevant art. A claim that contains more than one means-plus-function element should not be construed to require that each means-plus-function element must be a structurally distinct entity; rather, such claim should be construed merely to require that the overall combination which implements the invention must, as a whole, implement at least the functions called for by the claims
