Abstract
Description
- This application claims benefits under 35 U.S.C. § 120 based on provisional patent application Ser. No. 60/471,050, filed May 16, 2003.
- This invention relates to fasteners for composite materials, and more particularly, to fasteners that reduce mushrooming and splitting in composite materials without predrilling, while adequately fastening the composite material to a substrate.
- Modern composite building material is predominantly made of a combination of wood and plastic. Composite material can be used for various purposes, such as outside decks for houses.
- When normal screws are used with such composite materials, the material tends to “mushroom” when the screw is countersunk, leaving a bump above the surface of the board. Conventional screws also tend to split the ends of the boards unless holes are pre-drilled, which is labor intensive. Thus, there is a need for screws for composite materials that reduce both mushrooming and splitting.
- In many applications, composite material is fastened to an underlying substrate, such as wood. The fasteners must pass through the composite material and be firmly secured to the substrate.
- Accordingly, one object of this invention is to provide new and improved fasteners for composite material.
- Another object is to provide new and improved fasteners for composite materials that reduce mushrooming when the fastener is countersunk.
- Still another object is to provide new and improved fasteners for composite materials that reduce splitting without pre-drilling.
- Yet another object is to provide new and improved fasteners that adequately secure composite material to a substrate.
- In keeping with one aspect of this invention, a fastener has a shaft, a head at a first end of the shaft, and a point at the other end of the shaft. A first portion of the shaft adjacent the point is threaded. The first portion typically extends about one-half the total length of the shaft. A second portion of the shaft (adjacent the head) is not threaded, but has a plurality of spaced rings. A knurled portion can be provided between the first and second portions, if desired. Conventional symmetrical or asymmetrical thread can be used in the threaded portion, or a full three lobe thread can be used.
- The above mentioned and other features of this invention and the manner of obtaining them will become more apparent, and the invention itself will be best understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawings, in which:
- FIG. 1 is a partially cut-away view of one embodiment of a fastener made in accordance with the present invention;
- FIG. 2 is a an end view of the head of the fastener of FIG. 1;
- FIG. 3 is an expanded view of the inside of the head of the fastener of FIG. 1;
- FIG. 4 is a detailed view of the threads of the fastener of FIG. 1;
- FIG. 5 is a partially cut-away view of a second embodiment of the present invention;
- FIG. 6 is an end view of the head of the fastener of FIG. 5;
- FIG. 7 is an end view of the threaded portion of the fastener of FIG. 5; and
- FIG. 8 is a detailed view of a thread in the fastener of FIG. 5.
- As seen in FIG. 1, a
fastener 10 has ashaft 12 and ahead 14 on one end of theshaft 12. The other end of theshaft 12 has apoint 16, such as an approximately 30° point. - A
first portion 18 adjacent thepoint 16 has a plurality of threads, while asecond portion 20 adjacent thehead 14 is not threaded. Threerings second portion 20. It is contemplated that up to five rings would be suitable, depending on the nature of the material being fastened. - A
knurl section 24 can be provided between thefirst portion 18 and thesecond portion 20, if desired. The knurl typically has a plurality of teeth oriented parallel to the axis of the shaft. - The head14 (FIG. 2) can accept any suitable drive, such as the drive shown in FIG. 2, which has six
lobes 27. Aninside edge 26 of thehead 14 can include an undercut 28, in which the edge is inverted towards thehead 14, as seen in FIG. 3. - The rings are generally perpendicular to the axis of the shaft, can have a 50° beveled edge toward the head, and can be about 0.03-0.02 inches thick. In FIG. 1, the spaces between the three rings are unequal. In a No. 8 size screw having 12 threads per inch and a nominal length of about 2.5 inches, the
ring 22 can be about 0.560 to 0.540 inches from abearing surface 33 of thehead 14. Thering 23 can be about 0.395 to 0.375 inches from thesurface 33, and thering 25 can be about 0.17 to 0.15 inches from thesurface 33. Other screw sizes and lengths can have rings spaced in a similar manner, depending on the material being fastened. Thus, if the total length of the shaft from theinside surface 33 of the head to thepoint 16 is TL, then thering 22 can be located about 0.23 TL from thesurface 33, thering 23 can be located about 0.16 TL from thesurface 33, and thering 25 can be located about 0.07 TL from thesurface 33. -
Threads 29 in theportion 18 can be any suitable thread design, such as the design shown in FIG. 4, in which the surface facing thepoint 16 is at about a 30° angle to a line (the apex of the thread) perpendicular to the shaft axis, and the surface facing thehead 16 is at about a 15° angle to the same line. - A type17
shank slot 30 or the like is typically provided adjacent thepoint 16. Theslot 30 preferably would remove a full quadrant of theshaft 12 andthread 29. - A second embodiment of the present invention is shown in FIGS. 5-8. A
fastener 50 includes ashaft 52, ahead 54 at one end of the shaft, and apoint 56 at the other end of the shaft. A first portion 58 (adjacent the point 56) is threaded, and a second portion 60 (adjacent the head 54) is not threaded, but has three equally spacedrings portion 58 is about half the length of theshaft 52. - The
head 54 can include any suitable drive, such at the square drive shown in FIG. 6. In this embodiment, there is no undercut on aninside edge 73 of the head, although one could be provided, if desired. - A type17
shank slot 70 or the like is typically provided adjacent thetip 56, shown in FIGS. 5 and 7. FIG. 7 also shows that thethreads 69 are formed in threeradial lobes 64, each lobe spanning about 120° around thepoint 56. - As seen in FIG. 8, the
threads 69 have one surface which forms about a 15 °angle with aline 71 generally perpendicular to the axis of the shaft. That surface faces the point of the fastener. The opposite surface of the threads faces the head, and forms about a 5 °angle with theline 71. - The
rings shaft 52. In a No. 8 12 thread per inch screw, nominally 2.5 inches long, thering 62 is located about 0.31-0.30 inches from abearing surface 73 of the head, thering 63 is located about 0.21-0.20 inches from thesurface 73, and thering 65 is located about 0.1-0.10 inches from thebearing surface 73. As with the first embodiment, different screw sizes and lengths would have rings spaced in similar proportions. For example, if the total length of the shaft from the bearingsurface 73 to thepoint 56 is TL, then thering 62 is located about 0.13 TL from the bearingsurface 73, thering 63 is located about 0.08 TL from thesurface 73, and thering 65 is located about 0.04 TL from the bearingsurface 73. - In use, the fasteners of the present invention can be screwed into composite materials of varying densities without pre-drilling, and securely fasten the composite material to various substrates, without mushrooming or splitting the composite material.
- While the principles of the invention have been described above in connection with specific apparatus and applications, it is to be understood that this description is made only by way of example and not as a limitation on the scope of the invention.
