BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin ring used for travel and for ordinary shoulder bags, bags and the like.

[0002]

2. Description of the Related Art A ring made of synthetic resin is, for example, Shoukaisho 5
As shown in FIG. 8 of the microfilm in which the specification and drawings attached to the application No. 9-17314 (Japanese Utility Model Application No. 57-112285) are photographed, the main body portion extending in the horizontal direction and its both ends are on the same side. Consisting of legs extending in parallel,
A connecting body structure is known in which a U-shaped belt having an opening at the bottom is connected.

On the other hand, Japanese Utility Model Publication No. 46-28823 discloses a ring main body having a forked annular connecting leg formed in the upper portion by sheet metal working, and a spherical bulge integrally formed in the lower end through a neck portion. A ring made of metal, which is formed of an annular belt attachment body having a portion, and in which the neck portion is projected from the forked portion of the leg portion and the bulging portion is loosely fitted in the annular connecting leg portion is disclosed. ing.

[0004]

Of the above-mentioned conventional techniques,
The belt connecting body made of synthetic resin, which is disclosed in Japanese Patent Application No. 57-112285, is formed in a U-shape with a main body extending horizontally and legs extending downward from both ends of the main body. Then, the shaft portions at both ends of the locking body integrally formed with the ring body are rotatably fitted into the locking holes formed facing the leg portions of the coupling body, and the ring body is belt-connected. Since it is formed so as to be rotatable around the shaft portion with respect to the body, when a ring is used, when a large load is applied to the belt connecting body and the ring body in the pulling direction,
In particular, since it is made of synthetic resin, it is apt to be elastically deformed, and the two legs open to the outside, and the ring main body falls off from the belt connecting body, which is a problem of dropout.

Further, since there is no member between the belt attaching body and the leg portion, the belt attached to the belt attaching body causes rotation and swing of the bulging portion of the ring main body. There was a problem such as blocking the.

Further, since the belt main body and the ring main body are separately molded, and when the both are reassembled, a forcing force is applied to the assembled part to temporarily elastically deform the part. There is also a manufacturing problem that the parts are easily deteriorated and the manufacturing cost increases due to the assembling work.

On the other hand, in the ring made of metal disclosed in Japanese Utility Model Publication No. 46-28823, the bifurcated leg portion for connecting the belt attachment body formed on the upper part of the sheet metal ring body is made of sheet metal. Therefore, it is inevitably inevitably arranged side by side in a direction orthogonal to the hook surface of the main body, and the belt attachment body integral with the bulging portion loosely fitted between the leg portions also swings. Inevitably, it becomes one direction in the front and back toward the hook surface. Therefore, for example, when the ring body formed by pressing the bags and the like attached to the eggplant ring is in an immovable state, if for some reason an unreasonable horizontal force is applied to the belt attachment body, Even if it can swing, it does not swing in the direction orthogonal to it,
The neck, which is a rigid body, breaks without elastically deforming.

Furthermore, when a large force acts on the bulging portion formed on the belt attachment and the bifurcated leg portion engaging with the bulging portion in a direction to pull them apart from each other, the metal plate is rolled up. There is also a problem that the formed leg part easily returns to the original flat plate shape, and the ring body comes off from the belt attachment part.

The present invention has been made for the purpose of simultaneously solving the above-mentioned problems.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object and solve the problems, the present invention provides a belt with a bulging portion integrally formed on the upper portion of a ring main body through a neck. In a ring made of synthetic resin, which is connected to a synthetic resin belt attaching body including an attaching portion and a connecting portion via the connecting portion, the connecting portion has a through hole for accommodating the bulging portion in an intermediate portion. Together with a pair of connecting leg portions extending below the belt attaching portion in parallel with each other with a space narrower than the width of the belt attaching portion and a space portion in which the neck portion is loosely fitted, The bulging portion is a rod-shaped member that is loosely fitted in the through hole of the leg portion, and the belt attachment body and the ring body are the same in a coupled state. It is configured to be integrally molded.

[0011]

According to the present invention, with the above construction, the length of the connecting reinforcing rod can be made short so that the pair of legs can be as close as possible to the width of the belt attaching portion. Since the rod-shaped bulging portion of the eggplant ring body is loosely fitted in the through hole of the leg portion in an inserted state, even if the load in the pulling direction on the belt attachment body with the eggplant body concentrates on the base portion of the leg portion. The opening of the legs is completely prevented by the connecting reinforcing rod and the bar-shaped bulging portion. That is, the connecting reinforcing rod and the bar-shaped bulge are
It acts to prevent the pair of legs from opening outward when a large load is applied in the opposite direction to the belt attachment body and the ring body.

Further, the rod-shaped bulging portion is loosely fitted in the through hole of the leg portion, and the ring body can be swung between the leg portions of the belt attachment body, and the distance between both leg portions is minimized. Since it can be made as narrow as possible, the direction of the ring body that is made in response to the twist of the belt against the load from the outside tends to change, and it is easy to do without applying local load to each part connecting the belt attachment part and the ring body. Orient the eggplant body in the swing direction.

Further, since the ring of the present invention is integrally molded at the same time with the ring main body and the belt attachment portion being connected, it is not necessary to assemble both as in the conventional case, and therefore, the conventional case is not required. There is no forced elastic deformation during proper assembly, and naturally no local deterioration occurs.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2 as an example, (1)
Is an elliptical belt attachment body that is attached to a belt or the like, is made of synthetic resin, and has a pair of leg portions (10, 10) extending in parallel downwards. It is integrally formed at the lower end of 1). In the illustrated example, the leg portions (10, 10) are plate-shaped and face each other in parallel with each other through the space portion (11), and each leg portion (10, 10) has a circular cross section. Through holes (12, 12)
Are formed at locations facing each other through the space (11).

The base portions of the pair of leg portions (10, 10) are connected by a connecting reinforcing rod (1a) which is also integrally formed, and the upper portion of the belt attachment body (1) forms a belt attachment portion. , The leg portions (10, 10) and the connecting reinforcing rod (1
It constitutes a connecting portion for connecting the ring body (2) formed with a).

The eggplant ring body (2) is made by molding a synthetic resin and has a base portion (3), a hook portion (4) extending below the base portion (3), and an opening portion of the hook portion (4). It has a retaining piece (5) for closing and has a neck (13) of small diameter integrally on the upper side of the base (3), and further has a rod-shaped expansion perpendicular to the upper part of the neck (13). It has an exit (14). The neck portion (13) is made to have a diameter slightly smaller than the width of the space portion (11) between the leg portions (10, 10), and the length dimension of the rod-shaped bulging portion (14) is the leg portions (10, 10). It is longer than the width (D) of the space (11) between the legs (1).
(0, 10) through holes (12, 12) are formed to have substantially the same size as the end-to-end dimension.

A ring main body (2) that forms a belt attachment body (1)
The neck portion (13) extends through the space portion (11) and the rod-shaped bulging portion (14) forms the through holes (12, 1) of the leg portions (10, 10).
They are connected to each other in a loosely fitted state after being inserted into 2). Therefore, although not shown, this ring can rotate around the center line (6) of the ring formed by twisting the belt in cooperation with the belt attachment body (1), and as shown in FIG. , A plane parallel to the legs (10, 10), ie FIG.
The belt attachment body (1) and the ring main body (2) can be relatively swung within the plane in the normal direction including the center line (6).

Therefore, in this embodiment, the ring main body (2), which is an example, is in an immovable state, for example, the belt attachment body (1).
Even if a force is applied in a direction orthogonal to the normal line of the ring body (2), the belt attachment body (1) and the ring body (2) rotate together, and the neck portion (13) has the leg portion (10). , 10), the ring main body (2) can swing with respect to the belt attachment body (1) without being interfered with.

Moreover, the space (11) gap between the pair of legs (10, 10) is defined by the neck (13) of the ring body (2).
Since it suffices to set the thickness slightly larger than the thickness, the connecting reinforcing rod (1a) can be shortened, and further, the through holes (12, 1) of the leg portions (10, 10) of the belt attachment body (1) can be shortened.
Even when a large load in the pulling direction is applied to the belt body (1) and the ring body (2), the rod-shaped bulging portion (14) of the ring body (2) formed in 2) is inserted. The pair of legs does not expand and the ring body (2) does not come off the belt attachment body (1).

The synthetic resin ring thus constructed has the neck portion (13) extending into the space portion (11) and the rod-shaped bulging portion (14) penetrating the leg portions (10, 10). Hole (12,
It is possible to perform simultaneous molding in a single process while loosely fitting into 12). Belt main body (2) to form belt attachment (1)
In order to mold and in one step, as shown in one example in FIGS. 3 and 4, the main mold member (20,
20) and a pair of auxiliary mold members (21, 21) can be used. The main mold member (20, 20) includes the belt attachment body (1) and the leg portion (10, 10) described above, the base portion (3) of the ring body (2), the hook portion (4), and the retaining piece. The concave portions (1a, 10a, 3a,
4a, 5a) as well as the recess (1) corresponding to the neck (13).
3a) and a concave portion (13a) corresponding to a central portion of the bulging portion (14), that is, a portion located in the space portion (11),
It has recesses (16a, 16a) each having a semicircular cross section into which the auxiliary mold members (21, 21) are inserted. Recess (16
a, 16a) extends laterally from the recess (10a, 10a). The auxiliary mold members (21, 21) have concave portions (16
a, 16a) is formed in a bar shape having a radius substantially the same as the radius of curvature of the bulging portion (14) on the tip side, that is, a flat surface portion corresponding to the end surface of the bulging portion in the through hole (12) ( 14b, 1
4b) is formed.

In the mold thus manufactured, the main mold members (20, 20) are superposed on each other, and each auxiliary mold member (21, 20) is
21) may be molded in a state of being fitted into the space formed by the recesses (16a, 16a). By doing so, the other recesses (1a, 3a) excluding the recesses (16a, 16a).
a, 4a, 5a, 10a, 13a, 14a, 14b), the belt attachment body (1) integrally having the leg portions (10, 10), the neck portion (13) and the bulging portion (14) are integrally formed. And the neck portion (13) has a space portion (1).
1), and the bulging part (14) can be molded at the same time with the bulging part (14) inserted and loosely fitted in the through holes (12, 12) to form the belt attachment body (1) and the ring body (2). The assembly process is unnecessary. Through hole (12, 1) of leg (10, 10)
2) is formed by the auxiliary mold members (21, 21).

Incidentally, (22) in FIG. 4 is a gate for injecting a molten metal of the synthetic resin when the mold is used for injection molding of the synthetic resin.

(Effects of the Invention) As described above, according to the present invention, the rod-shaped bulging portion projecting through the upper neck portion of the ring body is made of synthetic resin and is composed of the belt attaching portion and the connecting portion. In a ring made of synthetic resin, which is connected to the belt attachment body via the connection portion, the connection portions are parallel to each other below the belt attachment portion via a space portion in which the neck portion is loosely fitted. Since a pair of connecting leg portions that are provided and extend in a portion narrower than the width of the belt attachment portion and a connecting reinforcing rod that connects between the base portions of the leg portions are integrally formed, the connecting reinforcing rod is formed. Even if a large load is applied to the belt attachment body and the ring body in the opposite direction, the two legs may open outward and the ring body may fall off the belt attachment body. The belt attachment body and the legs are sufficiently reinforced by the connecting reinforcement rod, and In combination with the structure capable of relative rotation of the ring attachment body and the ring main body, an excellent effect is obtained in that it is not damaged by external force.

Further, since the belt attaching body and the leg portion are blocked by the connecting and reinforcing rod, the belt attached to the belt attaching body rotates and rocks the bulging portion of the ring main body. Since it does not cause any trouble, the ring body has an effect of rotating and rocking very smoothly with respect to the belt attachment body.

Further, since the ring of the present invention is integrally molded at the same time with the ring main body and the belt attachment portion being connected together, it is not necessary to assemble the both as in the conventional case, and therefore the conventional case is not required. There is no forced elastic deformation during proper assembly, and naturally no local deterioration occurs.
