Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a U-shaped architectural nail generally called a staple.

[0002]

[Prior Art]

 As shown in FIG. 9, the conventional staple has a U-shape as a whole, and has leg portions extending at right angles from both ends of the U-shaped horizontal rod-shaped portion 5 so as to be easily driven into a member to be fastened. A certain U-shaped vertical rod-shaped portion 6 has a pointed structure. Then, as shown in FIG. 10, a stapler is driven in the direction of the arrow by using a nailing machine, so that the members to be fastened 1 and 2 are fastened.

FIG. 11 shows a staple of another conventional structure, in which the tip portions 6a and 6b of the tip portion of the leg portion 6 are cut in a shape inclined in opposite directions. Reference numerals 7a and 7b indicate the extending directions of the cut edge portions 6a and 6b, which are inclined by θ in the opposite directions with respect to the reference position 8. When a staple is driven into the fastened member, the legs 6 and 6 spread out in mutually opposite directions, as shown in FIG. 12, and the effect of preventing slipping out is high.

[0004]

[Problems to be solved by the invention]

 However, as shown in FIG. 9, the above-described first staple is used when the second member (interior material) 2 is attached to the surface of the first member (ceiling material) 1. There is a problem that the staples are easily removed due to the weight of the member (interior material) 2. Further, in the conventional second staple (FIGS. 11 and 12), a torsion moment acts on the lateral rod-shaped portion 5 when it is driven in, and there is a problem in durability.

Further, the first and second staples may be used as a means for connecting the two members in a state where the two members are abutted to each other as shown in FIG. 13, but it may not always be 2 depending on the driving direction of the leg portion of the staple. The two members to be welded were not always in a pressure contact state, and there was also the problem that the welding strength was affected. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a construction staple having excellent joint strength between fastened members.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a building staple according to the present invention is a U-shaped building staple in which a pair of leg portions have sharp tips, and the pair of leg portions are provided inside or outside the tip portions. The taper cut surface is formed symmetrically. According to a second aspect of the present invention, in the architectural staple according to the first aspect, a taper cut surface is formed on the outer side of the leg portion, and the staple body is hardened or made of high-tensile strength steel to enhance rigidity, The structure is such that the U-shaped vertical rod-shaped portion, which is the leg portion when driven into the fastening member, is less likely to be deformed than the U-shaped horizontal rod-shaped portion.

[0007]

[Action]

 When the staples are driven in, when the U-shaped vertical bar-shaped portion penetrates into the member to be fastened, it penetrates along the taper cut surface in the direction opposite to the taper cut surface forming side. That is, when the taper cut surface is provided inside the facing leg portion, the U-shaped vertical bar portion is opened as shown in FIG. 3, and conversely, the taper cut surface is located outside the facing leg portion. When provided, the legs are closed as shown in FIG. 7. The extending direction of the leg portion of the staple in the member to be fastened is oblique with respect to the direction in which the members to be fastened are separated from each other, thereby suppressing separation between the members to be fastened.

[0008]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of the present invention. FIG. 1 is a perspective view of a staple according to the present invention, FIG. 2 is a view for explaining a state in which the staple is driven, and FIG. It is sectional drawing which shows the mode fixed by the same staple.

In these drawings, a staple 10 has a rectangular horizontal cross section and is generally U-shaped, and U-shaped vertical rod-shaped portions 12 as legs extend at right angles from both ends of the U-shaped horizontal rod-shaped portion 11. On the inside of the tip of the U-shaped vertical bar-shaped portion 12, opposed taper cut surfaces 14 are formed. Then, when the staple 10 is driven into the fastened members 1 and 2 by the nail driving machine, as shown in FIG. 2, the component of the driving force P is applied to the tips of the legs along the taper cut surface 14. As a result, as shown in FIG. 3, the leg portion 12 enters in an oblique direction with respect to the driving direction (arrow direction), and the leg portion 12 is in an open state in which it is convexly curved inward, so that the member to be fastened is pulled out. The stopping effect is enhanced.

That is, FIG. 3 shows a state in which the interior panel 18 is fixed to the surface of the ceiling constituting member 16 by the staple 10. The self-weight of the interior panel 18 in this state acts in the direction of lowering the staple 10 downward, but the staple 10 falls off in the area shown by the shadow line of the ceiling constituting member 16 that comes into contact with the leg 12 in the open state. Prevent

4 and 5 show another embodiment of the present invention. FIG. 4 is a front view of a staple, and FIG. 5 is a view for explaining a usage state of the staple. The staple 10A shown in this embodiment has a structure in which the staple 10 of the first embodiment is quenched and processed to increase the rigidity strength. Therefore, as shown in FIG. 5, when the staple 10A is used to fasten the two members 21 and 22 together, the staple 10A is driven over the abutting portion between the members to be fastened. Then, since the rigidity of the staple 10 is high, the legs do not become so open when they are driven in like the staple 10 shown in the first embodiment, and the legs are not opened as shown in FIG. The members 21, 22 are held in pressure contact with the abutting surface 23 side, so that the joint strength between the members 21, 22 is enhanced. That is, the tightness of the abutting portion is high, and the two members 21 and 22 can be connected without a gap.

FIGS. 6 and 7 show a third embodiment of the present invention. FIG. 6 is a perspective view of a staple, and FIG. 7 is a diagram for explaining a usage state of the staple. In the above-described first and second embodiments, the taper cut surfaces 14 that face the inside of the tip ends of the leg portions, which are a pair of U-shaped vertical rod-shaped portions, are formed, but in the staple 10B of this embodiment, A taper cut surface 14 is formed outside the leg portion 12.

Therefore, when the staple is driven into the fastened member, the leg portion 12 enters along the taper cut surface 14, and as shown in FIG. 7, the leg portion 12 is in a closed leg state in which the leg portion 12 is curved outwardly convexly. The area shown by the shadow line of the fastened member 1 that contacts the leg portion 12 in the closed leg state prevents the staple 10B from falling off. FIG. 8 is a cross-sectional view of a state in which the staple shown in FIG. 6 is used while straddling the abutting portion of two members. When the staples are driven into the two members 21 and 22, the tip ends of the legs of the staple enter along the taper cut surface 14 (in the direction of the arrow), and the two members 21 and 22 are pressed against the abutting portion side. Therefore, in the state shown in FIG. 8, the two members 21, 22 are held in pressure contact with the abutting portion, and the two members 21, 22 can be connected without a gap.

In the second embodiment (see FIGS. 4 and 5), the staple 10A having a high rigidity is formed by quenching the staple 10, but the staple body is made of a high material. It may be made of tensile steel to increase the rigidity of the staples.

[0015]

[Effect of the device]

 As is clear from the above description, according to the building stapler of the present invention, the leg portion penetrates along the taper cut surface of the tip as it is driven, and the leg portion opens or extends in the member to be fastened. As the legs are closed and the fastening members are prevented from separating, it is possible to secure a fastening part with excellent fastening strength.
