DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be specifically described using the following embodiments as examples, but the present invention is not limited thereto. Unless otherwise specified, a configuration known to those skilled in the art can be used.

[0013] FIG. 1 shows a cross-sectional view of one embodiment of a nail driving aid 100 of the present invention when a nail 200 is being driven.

[0014] This nail driving aid 100 comprises a first part 10 having a cylindrical part 11 into which a nail 200 can be inserted and a self-supporting bottom part 12, a rod-shaped part 21 that can be inserted into the cylindrical part 11 and into which the nail 200 can be driven, and a second part 20 having a head part 22 that transmits the force of driving the nail to the rod-shaped part 21.

[0015] The cylindrical portion 11 of the first section 10 has a through-hole into which the nail 200 can be inserted. The through-hole of the cylindrical portion 11 communicates from its top surface 13 to a nailing surface 300 into which the nail 200 is driven. The rod-shaped portion 21 of the second section 20 can be inserted from the opening of the through-hole in the top surface 13 of the cylindrical portion 11. The opening of the through-hole of the cylindrical portion 11 that contacts the nailing surface 300 allows the nail 200 driven by the rod-shaped portion 21 of the second section 20 to be driven into the nailing surface 300. The nail 200 can be inserted from either the upper or lower opening of the through-hole of the cylindrical portion 11.

[0016] The length of the tubular portion 11 of the first part 10 can be substantially the same as the rod-shaped portion 21 of the second part 20, thereby allowing the entire length of the nail 200 to be driven completely into the nailing surface 300. For example, the length of the tubular portion 11 may be 5 cm or more, 10 cm or more, 15 cm or more, or 20 cm or more, or may be 50 cm or less, 40 cm or less, 30 cm or less, 25 cm or less, or 20 cm or less.

[0017] The cross-sectional shape of the through hole of the tubular portion 11 of the first part 10 is preferably, but not limited to, a circle so as to accommodate many types of nails 200. The size of the inner diameter of the tubular portion can be substantially the same as the outer diameter of the head 210 of the nail 200 to be used. For example, the inner diameter of the tubular portion may be 5 mm or more, 8 mm or more, 10 mm or more, or 15 mm or more, or may be 50 mm or less, 40 mm or less, 30 mm or less, 20 mm or less, or 15 mm or less. Note that, when referring to inner and outer diameters herein, if the shape is not circular, the diameter of a circle having the same circumference as the outer periphery of the shape can be considered to be the inner or outer diameter of the shape.

[0018] The tubular portion 11 of the first part 10 may be cylindrical, but is not limited thereto, and may be a polygonal prism such as a triangular prism or a quadrangular prism. The size of the outer diameter of the tubular portion 11 is not particularly limited as long as it has sufficient strength for use as the nail driving aid 100, but for example, the outer diameter of the tubular portion may be 10 mm or more, 15 mm or more, 20 mm or more, 25 mm or more, or 30 mm or more, or may be 80 mm or less, 60 mm or less, 50 mm or less, 40 mm or less, or 30 mm or less.

[0019] The free-standing bottom 12 of the first section 10 is connected to the tubular section 11. The shape of the free-standing bottom 12 is not limited as long as it can stably support the nailing aid 100 during nailing work, but for example, as shown in FIG. 1 , the free-standing bottom 12 can have a horizontal section 12a that is perpendicular to the tubular section 11 and in contact with the nailing surface 300.

[0020] For example, the freestanding bottom 12 of the first section 10 preferably has a horizontal portion 12a that is wide enough to be stepped on and fixed with a foot so that the user of the nailing aid 100 can stabilize the device when driving the nail 200. This allows the user to apply strong force when driving the nail. For example, the width of the horizontal portion 12a of the freestanding bottom 12 that can be stepped on with a foot may be 50 mm or more, 80 mm or more, 100 mm or more, or 150 mm or more, or may be 500 mm or less, 400 mm or less, 300 mm or less, 200 mm or less, or 150 mm or less.

[0021] The second part 20 has a rod-shaped part 21 that can be inserted into the cylindrical part 11 of the first part 10, and a head part 22 that transmits the force for driving the nail 200 to the rod-shaped part 21. The rod-shaped part 21 can move up and down within the through-hole of the cylindrical part 11 of the first part 10, and by striking the head part 22 in the direction of the nailing surface 300 with a hammer, hand breaker, or the like, the rod-shaped part 21 can drive the nail 200 into the nailing surface 300.

[0022] The rod-shaped portion 21 is not particularly limited as long as it has a configuration suitable for driving the nail 200 as described above, but it is preferable that at least the lower part of the rod-shaped portion 21 that contacts the head 210 of the nail 200 has an outer diameter that is substantially the same as or slightly smaller than the inner diameter of the tubular portion 11. The length of the rod-shaped portion 21 can be substantially the same as the length of the tubular portion 11 of the first part 10, as described above.

[0023] The head 22 of the second portion 20 can be driven in with a hammer, hand breaker, or the like, and is not particularly limited as long as it can apply an appropriate force to the rod-shaped portion 21. For example, the head 22 can have a larger outer diameter than the rod-shaped portion 21, thereby allowing the second portion 20 to have a flange 23. The flange 23 of the second portion 20 can come into contact with the upper surface 13 of the tubular portion 11 of the first portion 10 when the nail 200 is driven into the nailing surface 300.

[0024] The nailing surface 300 is not particularly limited, but the nailing aid 100 having such a configuration can drive the nail 200 into even a very hard surface. The nailing surface 300 can be, for example, a soft upper nailing surface 300, and the nail 200 can also be driven into a hard lower nailing surface 400.

[0025] For example, when constructing an asphalt pavement, there is a process in which an asphalt mixture is spread evenly on a base layer of asphalt mixture and then a surface layer is constructed, and in this process, a wooden formwork may be nailed onto the base layer of asphalt mixture. In such a case, as shown in Figure 1, the wooden formwork can serve as the upper nailing surface 300, and the base layer of asphalt mixture can serve as the lower nailing surface 400.

[0026] The nail driving aid 100 of the present invention can also be used as a method for fixing an upper nailing surface 300 made of a soft material to a lower nailing surface 400 made of a hard material with a plurality of nails. For example, this method includes the steps of (a) temporarily fixing a nail 200 to the upper nailing surface 300 made of a soft material, (b) inserting the temporarily fixed nail 200 from the lower part of the tubular portion 11 of the nail driving aid 100, (c) applying force to the head 22 of the second part 20 of the nail driving aid 100 to drive the nail 200 temporarily fixed by the rod portion 21 into the lower nailing surface 400 made of a hard material, and (d) if a plurality of nails 200 were temporarily fixed in step (a), performing steps (b) and (c) on another one of the nails 200, or if only one nail 200 was temporarily fixed in step (a), the method can include steps (a) to (c).

[0027] In the case of the asphalt pavement example described above, in step (a) of this method, a plurality of nails 200 can be simply hammered into a wooden formwork 300 at regular intervals with a hammer or the like, so that the nails 200 are able to stand upright in a substantially vertical position.

[0028] Thereafter, the nail driving aid 100 is placed over the temporarily set nail 200, and the nail 200 is inserted into the tubular portion 11 of the nail driving aid 100. Next, while stepping on the horizontal portion 12a of the self-supporting bottom portion 12 of the nail driving aid 100 with a foot to fix it, the head portion 22 is struck with a hammer, hand breaker, or the like, until the nail 200 is driven into the base layer 400 made of asphalt mixture. This process can be repeated for other temporarily set nails 200.

[0029] 2 shows a perspective view of another embodiment of the nail driving aid 100 of the present invention. In this embodiment, the nail driving aid 100 further includes, in addition to the first portion 10 and the second portion 20, a connecting portion 30 that connects the first portion 10 and the second portion 20 together in a state in which the rod-shaped portion 21 can move up and down at the tubular portion 11.

[0030] The presence of such a connecting portion 30 is extremely advantageous when using the nailing aid 100 to fasten multiple nails. That is, when driving multiple temporarily set nails one by one using the nailing aid 100 in the fastening method described above, the entire nailing aid 100 can be carried by simply holding the second portion 20. Then, with the rod-shaped portion 21 held in a raised position by holding the second portion 20, the temporarily set nail 200 can be inserted from the lower side of the tubular portion 11 of the first portion 10, and the nail 200 can be driven immediately by releasing the second portion 20. By repeating this process, multiple nails 200 can be driven into the nailing surface 300 very efficiently.

[0031] The first part 10 can have a first connecting portion 14 for connecting the connecting portion 30. The second part 20 can also have a second connecting portion 24 for connecting the connecting portion 30. The first connecting portion 14 and the second connecting portion 24 are not particularly limited in shape as long as they can connect the connecting portion 30, but as shown in Figures 3A and 3B, the first connecting portion 14 and the second connecting portion 24 may be grooves into which the connecting portion 30 can be fitted.

[0032] 3C, the connecting portion 30 may have a first annular body 31 and a second annular body 32. The connecting portion 30 may have four fixing portions 33 that connect the first annular body 31 and the second annular body 32. The four fixing portions 33 may be configured to be slidable when the first annular body 31 and the second annular body 32 are connected. The connecting portion 30 includes the first annular body 31, the second annular body 32, and the four fixing portions 33, which form a first tightening portion 30a and a second tightening portion 30b.

[0033] With this configuration, the connecting portion 30 can fasten the first fastening portion 30a to the groove of the first connecting portion 14 of the first portion 10, and the second fastening portion 30b to the groove of the second connecting portion 24 of the second portion 20. The sizes of the first fastening portion 30a and the second fastening portion 30b can be changed by sliding the fixing portion 33, thereby changing the strength with which the first fastening portion 30a and the second fastening portion 30b fasten the grooves of the first portion 10 and the second portion 20. Furthermore, when it is desired to detach the connecting portion 30 from the first portion 10 and / or the second portion 20, it can be easily detached by sliding the fixing portion 33.

[0034] Furthermore, by constructing the first annular body 31 and the second annular body 32 from an elastic material with appropriate strength, a restoring force can be imparted to the connecting portion 30. That is, if the first annular body 31 and the second annular body 32 are designed to return to a circular shape even after being deformed to an elliptical shape, the connecting portion 30 can have spring elasticity, and the first portion 10 and the second portion 20 can be connected by the spring. For example, the first annular body 31 and the second annular body 32 may be made of a metal wire with a diameter selected to have such spring elasticity.

[0035] 4A shows the nail driving aid 100 in a state where the second part 20 is grasped and the connecting part 30 is extended. In this state, the rod part 21 does not reach the bottom of the tubular part 11, so the temporarily set nail 200 can be easily inserted from the bottom of the tubular part 11.

[0036] 4B shows the nail driving aid 100 in a state where the temporarily set nail 200 has been driven from above and the connecting portion 30 has been compressed. This connecting portion 30 has a spring-like restoring force that allows it to return to a substantially circular shape. Therefore, after the nail 200 has been driven into the head 22 of the second portion 20, the connecting portion 30 returns to its substantially circular shape, allowing the rod-shaped portion 21 to rise up. [Industrial Applicability]

[0037] According to the present invention, a novel nailing aid that can easily transmit force to nails and easily drive multiple nails in succession, and a fastening method using the same, can be provided, and therefore the invention has high industrial applicability. [Explanation of symbols]
