Description

  The present invention relates generally to fasteners, and more particularly to screws having molded portions between helical ribs.

  FIG. 1 is a front view of a screw 10 in accordance with a prior art screw design. It may be difficult to engage the conventional screw 10 with the most conventional building materials such as plywood, panel material, cement board, one-by-material, two-by-material, particle board, composite wood and the like. Carpenters and do-it-yourself enthusiasts know how to turn the finished wood screw by hand, attach the flooring board with a screw gun, or just keep turning the screw 10 and nothing will happen. Everyone knows. The screw 10 does not engage, and when it is pushed down, the unstable screw 10 faces sideways, and the driver damages the processing surface and the presser. The problem lies in the screw tip, and as most carpenters know, many screws 10 are engaged by the helical ribs 12 of the screw 10 engaging the surface of the material, but this is a significant initial Stress may be required.

  Accordingly, there is a need in the industry to address the aforementioned deficiencies and shortcomings that have not been addressed previously.

  Embodiments of the present invention provide systems and methods for providing fasteners. Briefly described, in particular, one embodiment of the system can be implemented as follows. The system includes a rod body having a first end and a second end. The conical portion is integrally formed with the rod body at the first end of the rod body. The conical portion is tapered at the triangular tip. The triangular tip portion has at least one flat surface, a proximal end integral with the conical portion, and a generally tapered distal end. The notch is formed in the angle plane of the triangular tip portion. Large helical ribs are formed in the rod body and conical portion. The small spiral rib is integrally formed with the large spiral rib at the end of the first rib. A small helical rib extends over the conical portion and tapers towards the distal end of the notch. The grip portion is integral with the rod body and is in contact with the second end of the rod body.

  Another embodiment of the system can be described as follows. The system includes a rod body having a first end and a second end. The conical portion is integral with the rod body at the first end of the rod body. The conical portion is tapered at the triangular tip. The triangular tip portion has a proximal end integral with the conical portion and a generally tapered distal end. Large helical ribs are formed in the rod body and conical portion. The small spiral rib is integrated with the large spiral rib at the end of the first rib. A small helical rib extends over the conical portion and tapers towards a generally tapered distal end. A partial groove is formed in the conical portion along the proximal side of the small helical rib. The groove does not extend between all adjacent small helical rib elements. The grip portion is in contact with the second end of the rod body.

  Other systems, methods, features and advantages of the present invention will become apparent to those skilled in the art upon review of the following drawings and detailed description. All such additional systems, methods, features and advantages are included in this description, are intended to be included within the scope of the present invention and protected by the accompanying claims.

  Many aspects of the invention can be better understood with reference to the following drawings. The components of the drawings are not necessarily drawn to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

  FIG. 2 is a perspective view of a fastener 110 according to a first exemplary embodiment of the present invention. FIG. 3 is a front view of a portion of the fastener 110 shown in FIG. 2 in accordance with a first exemplary embodiment of the present invention. FIG. 4 is a side view of a portion of the fastener 110 shown in FIG. 3 in accordance with the first exemplary embodiment of the present invention. Fastener 110 includes a rod body 112 having a first end 114 and a second end 116. The conical portion 118 is integrally formed with the rod body 112 at the first end 114 of the rod body 112. The conical portion 118 tapers at the triangular tip portion 120. The triangular tip portion 120 has at least one flat surface 122, a proximal end 124 integral with the conical portion 118, and a generally tapered distal end 126. The notch 128 is formed in the angle plane 130 of the triangular tip portion 120. Large helical ribs 132 are formed in the rod body 112 and the conical portion 118. The small spiral rib 134 is integrally formed with the large spiral rib 132 at the first rib end 136. A small helical rib 134 extends over the conical portion 118 and tapers toward the distal end 138 of the notch 128. The grip portion 140 is integral with the rod body 112 and is in contact with the second end 116 of the rod body 112.

As can be seen from FIG. 2, the gripping portion 140 can be a handle 142. The handle 142 can be twisted to allow the fastener 110 to penetrate the surface. In an alternative design, the grip portion 140, for example, negative (flat head) slots that can be engaged with the driver, plus plus groove can be engaged with (Phillips ^TM) driver recess hexagon formed for example for Allen wrench, Alternatively, similar mechanisms known from other screw designs may be used. The gripping portion 140 can be a hook and can be used to twist the fastener 110 to penetrate the surface or to hang the article as a conventional hook function when the fastener 110 is secured. Other designs of gripping portion 140 are also contemplated and known to those skilled in the art and are considered to be within the scope of the present invention.

  As can be seen from FIG. 4, the triangular tip portion 120 has a narrow cross section. This cross section is partially narrowed due to the flat surface 122. The narrow cross section allows the fastener 110 to more easily achieve initial penetration of the surface when using the fastener 110. The flat surface 122 may continue from the tapered distal end 126 downwardly beyond the notch 128. Depending on the length of the flat surface 122, a small helical rib 134 toward the distal end 138 of the notch 128 can be included in the initial penetration of the surface. When the small helical rib 134 penetrates the surface, the fastener 110 is required to partially engage so as to continue to penetrate the surface.

  It is expected that the flat surface 122 typically provides some resistance to the act of twisting the fastener 110 and can cause surface splitting. As can be seen from FIG. 3, the notch 128 reduces the area of the left portion of the flat surface 122. It is this left portion that provides resistance when the fastener 110 is twisted clockwise. By forming the notch 128, a large portion of this resistance is removed.

  The flat surface 122 extends from the generally tapered distal end 126 over the upper end portion 144 of the small helical rib 134. At this time, the small spiral rib 134 extends one turn along the conical portion 118, so that the flat surface 122 does not interfere with this. Although the flat surface 122 appears to be formed in FIG. 4 by removing approximately half of the triangular tip portion 120, various portions of the triangular tip portion 120 may be removed and the flat surface without departing from the scope of the present invention. 122 can be formed.
