It is a single component in appearance and one component in terms of functions.

  The strap body 13 is formed by double molding as shown in (c) of FIG. 2 which is a cross-sectional view taken along line A-A of FIG. 2 (b). That is, as shown in FIG. 3, three of the attachment member 12, the base end 31 of the strap body 13 located on the attachment member 12 side, and the grip 32 of the strap body 13 located on the opposite side of the attachment member 12. It consists of two parts.

  The mounting member 12 is composed of a hook body 21 and an annular body 22, and the annular body 22 is integrally coupled rotatably around a shaft portion 23 vertically provided at the lower end of the hook body 21. The shape of the ring 22 is a semicircular outline shape, and has an inserted portion 24 through which the shaft portion 23 of the hook body 21 is inserted at the upper end, and a straight portion 25 held by the strap main body 13 at the lower end. . The annular body 22 is a single member, that is, a single member, and is seamless including the straight portion 25, that is, an integral structure having no joint or abutment portion.

  The attachment member 12 can also be formed of synthetic resin in addition to metal.

  The base end portion 31 constituting the strap body 13 is made of a synthetic resin, in particular made of a hard synthetic resin, and is formed in advance. On the other hand, the grip portion 32 constituting the same strap body 13 is made of a soft synthetic resin having both flexibility and flexibility, and is formed by covering a part of the base end portion 31 and molding.

  The detail of the proximal end 31 is shown in FIG. (A) of FIG. 4 is a front view of the proximal end 31, (b) is a side view, (c) is a B-B cross-sectional view. The base end 31 has a left-right symmetric shape in a front view shape and a side view shape, and the other end (drawing upper end in the drawing, the same applies hereinafter) on the mounting member 12 side and the other end (drawing in the drawing). In addition to the holding portion 33 for holding the mounting member 12 inserted from the lower end (the same applies hereinafter), the projection 34 is formed at the other end. Specifically, the base end portion 31 has a shape in which the other end side is opened in a bifurcated shape, and is formed in a reverse V-shape or a reverse U-shape in a front view.

  The portion on one end side of the base end portion 31 has a semicircular arc-shaped curved portion 35 and a linear extending portion 36 extending from both ends of the curved portion 35 to the other end, and has a thickness with sufficient strength. It is formed. The center of the curved portion 35 is the holding portion 33 described above, and the holding portion 33 holds the straight portion 25 of the ring 22. The size of the holding portion 33 is, as shown in FIG. 5, a circle having a size that allows the linear portion 25 to be loosely fitted.

  An introduction path 37 for inserting the straight portion 25 of the mounting member 12 is formed between the two extending portions 36 at the base end portion 31, that is, at a position on the other end side of the holding portion 33. The portion on the other end side of the introduction path 37 is wider than the diameter of the straight portion 25 held by the holding portion 33.

  At least a part of the introduction path 37, specifically, at a portion close to the holding portion 33, in order to prevent the falling off of the holding attachment member 12 held, a bottleneck portion 37a narrower than the diameter of the linear portion 25 is formed It is done. The bottleneck portion 37 a is formed by forming the protruding portion 36 a on the opposing inner side surfaces of the two extending portions 36. An inclined surface 36 b is formed at the other end of the protruding portion 36 a, that is, the end on the insertion side of the linear portion 25.

  At the other end of the extended portion 36, as shown in FIG. 4, a small diameter portion 36c whose width and thickness are slightly smaller than the portion at one end side therefrom is formed. The aforementioned projection 34 is formed straight from this small diameter portion 36c. That is, the projecting pieces 34 are formed on the two extending portions 36 that constitute the proximal end portion 31.

  The projecting portion 34 is a plate having a smaller width and thickness than the small diameter portion 36c, and the other end is formed in a semicircular shape in a side view. The projecting portion 34 is a portion which is entirely enclosed by the aforementioned gripping portion 32, and is formed with a penetrating notch 38 and a projection 39 projecting from the surface.

  The notches 38 are formed in a long side view oval shape in the longitudinal direction of the projecting piece portion 34, and two notches 38 are formed side by side in the longitudinal direction of the projecting piece portion 34. Two projections 39 are also formed on the inner side surface of the projection 34 in the longitudinal direction of the projection 34. One first protrusion 39 a of the two protrusions 39 is formed in a manner coupled to one notch 38 a of the two notches 38. That is, the first protrusion 39 a is formed across the notch 38 a and extends the entire width of the protrusion 34. The other second projection 39 b is formed between the notches 38 on the inner side surface of the projecting piece 34 and is formed shorter than the first projection 39 a.

  The proximal end 31 of such a configuration is molded using a mold 51 as shown in FIG.

  As shown in FIG. 6 which is an explanatory view of the manufacturing process of the hand strap 11, another mold 52 is assembled after the mounting member 12 is assembled to the formed base end 31 (FIG. 6 (b)). To form the grip 32 (FIG. 6 (c)). That is, the grip portion 32 is integrally formed with the projecting piece portion 34 of the proximal end portion 31. Although a bottleneck 37a is formed in the introduction path 37 of the proximal end 31, if the resin is soft after molding the proximal end 31, the straight portion 25 of the mounting member 12 is used as the bottleneck 37a. , And can be fitted into the holding portion 33.

  As shown in FIGS. 2 and 3, the grip portion 32 has a symmetrical shape in the front view shape and the side view shape, and is a closed flat annular shape. The hole portion 41 at the center of the grip portion 32 is formed in an appropriate size, such as a size that allows a hand to be inserted, for example.

  The thickness of the grip portion 32 is formed to the same thickness as the curved portion 35 and the extending portion 36 of the proximal end portion 31 described above, and the other end side is curved slightly larger than one end on the proximal end portion 31 side. Moreover, it has two branch parts 42 which are parted corresponding to the projection part 34 at one end, and it continues in the branch part 42, the opposing site | part of the holding part 33 holding the attachment member 12, in other words, it grasps A closed portion 43 for closing the introduction path 37 is formed at a portion of the proximal end 31 corresponding to the introduction path 37 when the portion 32 is formed.

  When integrally molding the grip portion 32 having such a shape with respect to the base end portion 31, the resin filled in the cavity to be the grip portion 32 enters the notch 38 of the base end portion 31 and wraps the protrusion 39. And is integrated with the proximal end 31.

  The hand strap 11 configured as described above is used by attaching the attachment member 12 to a portable item to be attached. FIG. 7 is a perspective view of a portable thermos bottle 55 as an example of a portable item.

  The hand strap 11 has a grip 32 integrally formed on a proximal end 31 for holding the mounting member 12, and the appearance of the strap body 13 is the appearance of a single article. That is, there is no seam, and a beautiful and innovative design can be obtained.

  Moreover, since the strap main body 13 is formed by integral molding so as to wrap the projecting piece portion 34 of the proximal end portion 31, tensile strength and durability can be enhanced. As a result, it can also be used for heavy portable items that have not been possible. When the carried item is a portable thermos bottle 55, it can be used, for example, for a metal vacuum double bottle with a large capacity of 1 liter or more.

  The high strength results from the direct coupling of the attachment member 12 to the strap body 13 and the elimination of the need for other members for coupling and the fact that the proximal end 31 is made of hard synthetic resin.

  In particular, since the notches 38 and the projections 39 are provided in the projecting piece portion 34 which is enclosed and integrated with the grip portion 32, a high bonding strength can be obtained. In addition, since the plurality of notches 38 and the plurality of protrusions 39 are provided and one notch 38a and the protrusion 39 (the first protrusion 39a) are coupled and disposed, the coupling strength can be enhanced also from this point.

  Also, since the ring 22 of the mounting member 12 is seamless, the ring body 22 is deformed and the joint or butt portion is not separated, and the strap main body 13 is not separated from the mounting member 12 and the durability is also good. .

  The grip portion 32 is formed of a soft synthetic resin having both flexibility and flexibility while having high strength as described above, and has a closed flat annular shape with a hole portion 41 into which a hand or the like can be inserted. Because there is, you can hold even if you put your hand. Because of this, it is easy to hold and handle.

  Furthermore, since the base end portion 31 has a shape in which the other end side is opened in a bifurcated manner, and the introduction path 37 into which the straight portion 25 of the mounting member 12 is fitted is formed at a position other than the holding portion 33 The operation of fitting the mounting member 12 to the proximal end portion 31 before molding of the grip portion 32 can be easily performed, and the workability is good.

  In addition, on the holding portion 33 side of the introduction path 37, a bottleneck portion 37a is formed which prevents the holding attachment member 12 from falling off, and the state where the straight portion 25 of the attachment member 12 is held by the holding portion 33 can be maintained. As a result, the positional relationship between the attachment member 12 and the strap body 13 can be suppressed to substantially only relative rotation. Also in this respect, the hand strap 11 is easy to handle.

  The above is one form for implementing this invention, and this invention is not limited only to the above-mentioned composition, and other composition is also employable.

  For example, the proximal end 31 may be made of a soft synthetic resin.

  Although the color of the strap main body 13 is not mentioned in the above description, the base end portion 31 and the grip portion 32 can be formed of resins of different colors as well as of the resin of the same color.

  The shape of the strap body 13 may not be flat as described above, may not be annular, and may not be symmetrical in a front view or a side view. It can be set appropriately according to the carried goods and the design.
