Description
Background of the Invention
(a) Field of the Invention
This invention relates to a dog nail mainly used to join wood or similar building materials. It is used to fasten L or T joints of post and cross bars, or similar window pieces, of wood building.
(b) Description of the Prior Art
In conventional buildings, L or T joints of posts and cross bars or similar window pieces are fastened with a long straight nail of which the pointed end is driven into the side surface of one piece of wood, and into the top surface of another piece. The firmness of the joint depends on the area and depth of the shank of the nail in the other piece of wood and the surface of the shank gripped by the fibers of the said piece of wood. Oftentimes, the head of the nail is so small that the nail is often driven out of the wood after having been driven in. It must be pulled out of the surface and driven in again. Furthermore, a nail which appears to be driven securely within both pieces of wood may not be and the joint will loosen after being used for a certain period of time.
Another type of fastening means used is a U-shaped fastener that looks like a staple and has sharp pointed ends that are driven into the side surfaces of an L joint as a reinforcement. This type of fastener can only serve as a reinforcement and can only be used after the joint is completed.
In short, a conventional L or T joint of two pieces of wood is secured by means of long nails and some are reinforced with U-shaped fasteners. The disadvantage of which construction is that with such nails and fasteners, the L or T joint is difficult to make and that the joint is not firm and durable.
Summary of the Invention
The dog nail of this invention for joining wood or similar building material can be made of iron or alloy plate. It is made by punching material out into a planar or right-angled I, T, L or other shape. Commonly, dog nails comprise a body and a plurality of spikes. The said spikes are V-shaped in cross section and perpendicular to the body. The punched spike may be situated near the end rib of the body so as to mate in holding wood with the edge spike extending from the end edge and bent there. In addition, the said body may have several nail holes so that reinforcement can be made with conventional nails in special conditions.

Description of the Preferred Embodiment
As shown in FIG. 1, the first embodiment is plane and I shaped. It comprises a plate (body) 10 and four spikes 20, 21, 22, 23. The body 10 has two reinforcing ribs 11, 12. Its section is shown in the detail by A--A line in FIG. 19. The body 10 also has two punched holes 13, 14 left after the spikes 21, 22, 23 are perpendicular to the body 10. The detail by B--B line in FIG. 20 is an enlarged cross-section of the spikes 20, 21, 22, 23. The cross-section of spikes is V-shaped which results in increased contact area with the wood and greater gripping force of the wood fibers. The punched holes 13, 14 are ready for reinforcing with conventional nails when the spikes 20, 21, 22, 23 go away or when reinforcement is needed.
FIG. 2 shows the application of the first embodiment. The spikes 20, 21, 22, 23 will be driven alternately with a hammer on the body 10 for holding two pieces of wood together. Additional nails may be driven through the holes 13, 14 into the wood as reinforcement if necessary.
FIGS. 3 and 4 show the second embodiment of this invention. It comprises a plane, T shaped body 10 and four spikes 20, 21, 22, 23. The body 10 also has reinforcing ribs 11, 12, 12' on the edge and three punched holes 13, 14, 15. The ribs 11, 12, 12' and the spikes 20, 21, 22, 23 are formed in the same way as those of the first embodiment. The application of the second embodiment is also same as the first embodiment. FIG. 21 is an enlarged view of spike 23 as shown in FIG. 3.
The third embodiment is shown in FIG. 5. It's body 10 is plane and L shaped and has also two reinforcing ribs 11, 12, two punched holes 13, 14 and four spikes 20, 21, 22, 23. Its construction is similar to the first embodiment and its application is shown in FIG. 6. FIG. 22 is an enlarged view of spike 23 as shown in FIG. 5.
The fourth and fifth embodiments are shown respectively in FIGS. 7 and 9. They comprise a body 10 and two spikes 20, 21. Each of the bodies 20 has two reinforcing ribs 11, 12, a punched hole 13 left when the spike 20 is formed, and two nail holes 16, 17. They are all formed in right angle. The only difference between the fourth and fifth embodiments is that the fourth embodiment has spikes 20, 21 on the outside and the fifth embodiment on the inside. They are suitable for holding two pieces of wood respectively on the inside and outside of the joint. The application of these two embodiments is shown in FIGS. 8 and 10. The spikes 20, 21 are driven first into one piece of wood and nails are then driven through the nail holes 16, 17 into another piece of wood so as to hold them together.
The sixth and seventh embodiments are shown in FIGS. 11 through 14. The T-shaped body 10 has reinforcing ribs 11, 12, 12' on the edge but is bent into a right angle. The body 10 also has a punched hole 13 and three nail holes 16, 17, 18. The difference between the sixth and seventh embodiments is that one is for inside application and the other for outside application. Their construction is the same as that of the fourth and fifth embodiments.
The eighth and ninth embodiments are shown in FIGS. 15 and 17. The body 10 is in double T-shape and bent at the bottom into a right angle. The body 10 has four reinforcing ribs 11, 11', 12, 12', three punched holes 13, 14, 15, three nail holes 16, 17, 18 and three spikes 20, 21. 22. Their construction is the same as the fourth, fifth, sixth and seventh embodiments and their application is shown in FIGS. 16 and 18.
From the above, it is clear that the dog nail of this invention which has spikes and nails to be driven into two pieces of wood can provide a firm joining means.
