Abstract

PROBLEM TO BE SOLVED: To lock a thick code without elongating the length of an arm by providing a recessed groove part in the inner end face of a flange, or preferably in the adjacent to the both sides of a hole approximately in parallel to the outer circumference of the flange. SOLUTION: A recessed groove 4 provided inside a flange has such a size as arranging a code therein and, when a rising part, 221 is pressed against it to the maximum, the shapes of the recessed groove 4, an arm part, 223 , and a holding part 23 are so decided as to arrange the code in a space formed by the holding part 23 and the groove part 4. When the rising part 221 is pressed against the hole 3 to the maximum, the shapes of holding part 23 the arm part 232 , and the hole 3 are so decided as to pass the code in a space formed by the holding part 23 and the hole 3 and arrange it in the holding part 23 or the recessed groove 4. That is to say, the height h1 of the recessed groove 4 is set to the height h0 of the flange outer circumference bent part 5, the width w1 is set to mach with the code diameter, and the length of the recessed groove 4 is so set that, when the code is guided from the inner end face of the flange to the recessed groove 4, it is prevented from loading a large bending on the code.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel having a locking member for easily locking the end of a metal filament wound on a reel to a reel, and particularly to a metal filament having a large wire diameter. The present invention relates to a reel for a metal striatum having a locking device suitable for locking.

[0002]

2. Description of the Related Art A metal filament having a locking member which can easily lock a winding end of a metal filament such as steel cord and can easily release the locked end terminal. As a reel for use, the inventors have proposed a reel which can be easily locked inside the flange of the reel (Japanese Patent Application No. 04-28).
No. 2388).

[0003] That is, the proposed reel has a fixing member comprising a fixing portion, a bridging portion formed of an elastic body continuous with the fixing portion, and a grip portion connected to the bridging portion, and the bridging portion moves on the flange. The cross-linking portion extends from the fixing portion away from the outer end surface of the flange, and then bends toward the hole above the passage hole, and then continues to the grip portion.

The fixing portion of the locking device is fixed to the outer end surface of the flange, and a stress is applied to the bridging portion in the direction from the outer end surface of the flange to the inner end surface to move through the hole through the gripping portion and move in the direction of the flange winding drum. Then, a gap is provided between the grip portion and the inner end face of the flange. After the cord is disposed in the gap, the applied stress is released, and the elastic force of the bridging portion causes the grip portion and the inner end face of the flange to form a gap. This is an inside stop reel that locks the end of the cord wound around the reel holding the cord inside the reel flange.

[0005] Li already invention - in Figure 5 the part of Le 10 shows schematically, the fixing portion 12 ₁ and the bridge portion 12 of the fastener 12
₂ and consists of the grip portion 12 _3, further bridging portion 12 ₂ extending from the rising portion 12 ₂₁ and the bending portion 12 ₂₂ up to which bent from the fixing portion 12 ₁ to the grip portion 12 ₃ A - arm part 1
2 ₂₃ , but there are certain restrictions on the shape of each part of the locking tool 12.

Namely, FIG. 5 is in the form of a state of not holding the metal striatum fastener 12, the outer peripheral height of the bent portion 22 ₁ of the locations 12 ₂₂ bending of the bridge portion 12 ₂ is flange 22 it is necessary to not exceed h _2, or flange outer peripheral bent portion 22 ₁ of the height Li is higher than h ₂ - because become an obstacle when storing and staked Le 10 horizontally. Also that the grip portion 12 ₃ is not inwardly projecting inner end face flange 22, i.e. the grip portion 12 ₃ is because an obstacle when winding the metal striatum when projecting to the inside of the inner end face flange 22.

[0007] Figure 6 is in the form of when pressing the bridge portion 12 ₂₁ in the flange inner, co - Upon gripping the winding end of de by the gripping portion 12 _3, the grip portion 12 ₃ and the inner flange 22 end surface since it is necessary that the de diameter than the crosslinked part 12 ₂ of the a - - gap s child to form arm portions 12 ₂₃ require a predetermined length. Here in FIG. 6 and the rising portion 12 ₂₁ of the bridge portion 12 ₂ A - arm portions 12 ₂₃ are required to be substantially perpendicular. That is, the rising portion 12 ₂₁
When pressed maximize, rising portions 12 ₂₁ A when its ready to stuck to the flange 22 side is - arm part 12 ₂₃ and point bend in order to increase the gap s is formed in the end face flange 22 12 ₂₂ This is because it is necessary that substantially the diameter.

[0008] Due to the above restrictions, a large diameter core
When trying to lock the de, bridge portion 12 ₂ of the A - but must increase the length of the arm portion 12 _23, in which case,
Bending point 12 _{22 when the} cord is not locked
There in order not to exceed the outer peripheral bent portion 22 ₁ of the height h ₂ of the flange 22, the bridge portion 12 ₂ of the A - rising portion 12 ₂₁ to arm portion 12 ₂₃ is shown in FIG. 7 and the flange surface 1 in angle a to be formed must be as close to 90 °, i.e. a - angle a larger the length of the arm portion 12 ₂₃ is close to 90 °,
As a result, the rising portions 12 ₂₁ of the bridge portion 12 ₂ is shortened. Such bridge 12 ₂ of the rising portion 12 ₂₃ is difficult to press, also because there is a problem that the mechanical fatigue of the material of the rising portion 12 ₂₃ is promoted, to lock the inner stopper locking device There was a limit to the diameter of the metal striatum that could be used.

[0009]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object to be solved by the present invention is an internal stop reel,
An object of the present invention is to provide a reel which can easily lock a metal wire having a large diameter.

[0010]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is intended to be continuous with a fixing surface fixed to an outer end surface of a flange and a fixing portion so as to be separated from the outer end surface of the flange. It has a bridging portion made of an elastic body which bends toward the hole over the hole after extending, and a locking tool consisting of a grip portion connected to the bridging portion. The arm portion of the bridging portion moves to the flange. An inner stop reel provided with a hole which can be formed in the inside of the flange, wherein a concave groove portion is provided on the inner end face of the flange, preferably on both sides of the hole and substantially parallel to the outer periphery of the flange. It depends on the reel.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The concave groove provided on the inner end face of the flange has a size in which a code can be arranged in the groove, and is formed by a grip portion and a groove portion when the rising portion is pressed to the maximum. The shape of the groove, the length of the arm portion, and the shape of the grip portion are determined so that the code can be arranged in the space to be formed.

Further, the size of the hole is limited by the space formed by the grip portion and the hole when the rising portion is pressed to the maximum.
The shape of the grip portion, the shape of the arm portion, or the shape of the hole is determined so that the wire can be passed through and placed in the grip portion or groove.
