Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rope, a cord,
The present invention relates to a hook for hooking a linear material such as a string or a band.

[0002]

2. Description of the Related Art For example, a flagpole displaying a flag usually includes a flagpole.
A rope is installed to lift and lower the flag while the flag is attached.Furthermore, in order to maintain the tension of the rope, a hook for winding and hanging an excess portion of the rope is mounted on the ground. It is provided in the part near. FIG. 3 shows a conventional example of such a hook. This hook has a torii shape in which a pair of stays 41 are fixed to a rod-shaped hook body 40, and the longitudinal direction of the hook body 40 is set in the direction in which the flag pole (fixed member) P extends. At the same time, the stay 41 is fixed to the outer surface of the flag pole P. Rope R
Is used so as to be wound around and connected to both stays 21, and the hook body 40 projects from the stays so that the ropes R do not come off.

[0003]

According to the above-mentioned conventional latch, a plurality of ropes R are sandwiched between the flag pole P and the latch main body 40 as shown in the figure. However, it was difficult to wind the rope orderly and tightly so that the winding state would not loosen. That is, the rope R
Of the winding portion of the flag pole P is likely to be loosened, so that the tightly wrapped rope R is also loosened, which causes dissatisfaction such as a hitting sound on the flagpole P or impaired appearance. Further, it takes time and effort to tie and untie the rope R, and the knot of the rope R may also impair the appearance.

[0004] Therefore, the present invention can reliably hook a linear material such as a rope without loosening, can perform the work of hooking and releasing very easily, and further impair the appearance. It is an object of the present invention to provide a hook for a linear material without any.

[0005]

Means for Solving the Problems A first invention of the present invention is:
A fixed portion fixed to the fixed member and a wedge portion connected to the fixed portion are provided, and in a state where the fixed portion is fixed to the fixed member, the wedge portion is formed at an acute angle with respect to the fixed member. It is characterized in that it forms a wedge-shaped narrow corner portion which can extend and be tightly sandwiched between the linear member and the fixed member.

[0006] The latch of the first invention is used by fixing a fixing portion to a member to be fixed. The fixed member is an article or a structure to which the hook is fixed, such as the flagpole described above. In this fixed state, a wedge-shaped space is formed between the fixed member and the wedge portion as the narrow corner portion. In order to hook the wire, the wire is pressed into the narrow corner while being pulled. As a result, the linear material is tightly sandwiched and locked between the fixed member and the wedge portion. If a plurality of linear members are sandwiched in a state of being adjacent to each other, loosening is likely to occur as in the conventional case, but in the present invention, only one line is sandwiched between the fixed member and the wedge portion, so that loosening is unlikely to occur. Therefore, the linear material is securely hooked on the hook. In addition, in order for the linear material to be tightly sandwiched between the narrow corners,
It is desirable that the single linear member is pressed against the fixed member and the wedge portion, and further, a space serving as a pull allowance remains inside the linear member at the narrow corner portion.

In order to release the wire from the hook, the wire may be pulled in the direction opposite to the press-fitting direction to release the hook at the narrow corner. Therefore, the work of hooking and releasing the linear material can be performed extremely easily. Furthermore, since the hooking is reliably performed, it is not necessary to tie the wire material daringly. For this reason, it is possible to prevent the appearance from being impaired by, for example, winding all the surplus portion of the wire material around the hook. Can be avoided.

Next, a second invention of the present invention comprises a fixing portion fixed to a member to be fixed, and a wedge portion connected to the fixing portion, and the fixing portion and the wedge portion are formed at an acute angle with each other. It is characterized in that a wedge-shaped narrow corner portion is formed which intersects and between which the one linear material can be tightly sandwiched.

[0009] Even in the second aspect of the present invention, there is a narrow corner portion in which the linear material can be tightly sandwiched. Although the first narrow corner portion is formed between the fixed member and the wedge portion,
The second invention is different from the first invention in that a narrow corner portion is formed between the fixing portion and the wedge portion. However, the operation and effect obtained by hooking the linear material on the narrow corner portion are the same as those of the first invention. In addition, according to the second aspect, the linear member can be separated from the fixed member and can be hung. For example, when the linear member is installed outdoors, rainwater is transmitted to the linear member and the fixed member becomes dirty. Such an effect can be prevented.

In the first and second aspects of the present invention, the angle of the narrow corner portion (that is, the intersection angle between the fixed member and the wedge portion in the first invention, and the intersection angle between the fixed portion and the wedge portion in the second invention) Is) because the wire can be tightly pinched
It is preferably 0 ° or less, more preferably 50 ° or less. The angle, which can be tightly sandwiched by the characteristics of the linear material such as elasticity and coefficient of friction, and the material, may vary, but an angle exceeding 70 ° is not preferable because the linear material easily comes off.

The wedge portion in the present invention can take various forms. For example, the wedge portion may be formed in a rod shape. The present invention can be realized if at least one wedge portion is provided, but from the viewpoint of securing the linear material more securely, the plurality of wedge portions are linear or radial around the fixing portion. The preferred form is that it extends to In this case, a linear material is wound around a narrow corner formed by each wedge to be hooked. In addition to this, the wedge portion may have a disk shape. In this case, the length of the portion where the linear material is engaged, that is, the length sandwiched between the fixed member and the wedge portion, or the fixed portion and the wedge portion can be increased, and as a result, the engaging force increases, which is preferable.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings. (1) First Embodiment FIG. 1A is a side view showing a state in which a hook 1 according to a first embodiment is fixed to a tubular flagpole P, and FIG. 1B is a front view thereof. The hook 1 is an elongated plate-like member, and has a vertically symmetric shape in which a wedge 3 is bent and extended in the thickness direction from both ends of a fixed portion 2 extending straight in the center. The wedge portion 3 is formed in a substantially 1/8 arc that is curved at a constant curvature. The hook 1 has a flagpole P
The fixing portion 2 is fixed to the outer surface of the flagpole P in accordance with the longitudinal direction (vertical direction) of the flagpole P. The means for fixing the fixing portion 2 to the flagpole P is arbitrary, but in this case, the fixing portion 2 is fixed by the screw 4.

As shown in FIG. 1A, a narrow corner portion 5 is formed between a wedge portion 3 which is vertically arranged in a state where the hook 1 is fixed to the flag pole P and the outer surface of the flag pole P. Each is formed. Here, the angle θ formed by the tangent S of the wedge 3 and the outer surface of the flagpole P is the angle of the narrow corner 5, and the angle θ is about 45 °. The angle of the narrow corner portion 5 is set to an angle at which one rope of the flag pole P can be tightly sandwiched. FIG. 1A shows this state. When one rope (linear material) R is pressed into the space between the wedge portion 3 and the flag pole P while being pulled toward the fixing portion 2, the rope R is deformed. We crimp to wedge part 3 and flagpole P,
Further, a space serving as a pull allowance remains inside the rope R in the narrow corner portion 5.

A description will be given of a case where a rope R hanging from above is hung on the hanger 1 having the above structure. First, the rope R is tensioned, and then a single rope R is attached to the lower narrow corner portion 5. It is inserted between the wedge portion 3 and the flagpole P while being inserted from the side and pulled toward the fixing portion 2. Next, the rope R is turned up and put in the upper narrow corner portion 5 and press-fitted in the same manner. As a result, the rope R is tightly sandwiched between the wedge portion 3 and the flag pole P at the upper and lower narrow corners 5 and is hooked. The surplus portion of the rope R may be continuously wound around the upper and lower narrow corners 5, or may be hung as shown in FIG.

According to the above-mentioned hook 1, the rope R can be hooked by press-fitting one rope R between the wedge portion 3 and the flag pole P and tightly sandwiching it. If a plurality of linear members are sandwiched in a state of being adjacent to each other, loosening is likely to occur as in the related art. However, in the hook 1 of the present embodiment, only one line is sandwiched between the wedge portion 3 and the flag pole P. , Less loosening. Therefore, the rope R is securely hooked on the hook 1. In order to remove the rope R from the hook 1, the rope R is pulled in the direction opposite to the press-fitting direction so that the narrow corner portion 5 is removed.
You only have to remove the hook to the. Therefore, the work of hanging and releasing the rope R can be performed extremely easily. Further, since the hook is securely held, there is no need to tie the rope R daringly. Therefore, it is possible to prevent the appearance from being impaired by, for example, winding the entire surplus portion of the rope R around the hook 1. it can.

The hook 20 of the second embodiment has a shape in which a pair of stays (fixed portions) 22 extend from the back surface of an elongated plate-shaped wedge portion 21 that extends straight. This hook 2
In the case of 0, each stay 22 is fixed to the outer surface of the flagpole P with its longitudinal direction aligned with the longitudinal direction (vertical direction) of the flagpole P. Each stay 22 extends obliquely along the direction in which the wedge portion 21 extends while being separated from each other, and an angle (for example, about 45 °) at which the rope R can be tightly sandwiched between the wedge portion 21 and the upper and lower stays 22. Are formed respectively.

According to the hook 20 of the second embodiment,
The rope R can be hooked by press-fitting one rope R into each narrow corner portion 23 formed between the wedge portion 21 and each stay 22, and the operation effect is the first effect. This is the same as the embodiment. Further, according to the hook 20 of the second embodiment, the rope R can be separated from the flag pole P and can be hooked, so that it is possible to prevent a problem that rainwater is transmitted to the rope R and the flag pole P becomes dirty. It works.

(3) Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIG. The hook 30 according to the third embodiment has a fixed portion 32 formed on the back surface (convex side) of a central portion of an elongated plate-shaped wedge portion 31 formed in an arc shape. Fixing part 3 according to the longitudinal direction (vertical direction) of P
