In the rotary small case, holes are formed in the lid and the main body. Then, the rotary holder integrally includes a thin plate-shaped base portion and projection portions that vertically project from one of the planes of the base portion and are fitted into the hole portions at two locations separated by the predetermined distance. It is a resin molded product, and the predetermined range on the tip side of the protruding part is made a large diameter part with an outer diameter larger than the inner diameter of the hole part, and the length of the hole part is closer to the base side than the large diameter part. It is characterized in that a range of substantially equal length is made a small diameter portion having an outer diameter substantially equal to the inner diameter of the hole portion, and a slit extending from the tip to the small diameter portion is formed.

[0009]

[Action]

 In this invention, the rotation holder is integrally resin-molded with the base and the two protrusions protruding from the base. This protruding part consists of a large diameter part on the tip side and a small diameter part on the base side.The outer diameter of the large diameter part is larger than the inner diameter of the hole of the lid and the main body, and the outer diameter of the small diameter part is the inner diameter of the hole. Is approximately equal to. In addition, a slit is formed from the tip to the small diameter part. That is, there are slits over the entire range of the large diameter portion.

Therefore, when the two protrusions of the rotary holder are pushed into the holes of the lid and the main body so as to face each other, the large-diameter portion having an outer diameter larger than the inner diameter of the hole has an inner peripheral surface of the hole. Is pressed from both sides of the slit, elastically deforms to reduce the diameter, and fits into the hole. When the base is pushed further toward the lid and the main body, the large-diameter portion is exposed inside the lid and the main body, and the small-diameter portion is located inside the hole. The large-diameter portion exposed inside the lid and the main body is no longer pressed by the hole and is restored by the elastic force. The outer diameter of the large-diameter portion becomes larger than the inner diameter of the hole, and the protruding portion cannot come out of the hole.

【Example】

 FIG. 1 is an assembly view of a rotary accessory case which is an embodiment of the present invention. The rotary accessory case 1 is divided into a lid 2 and a main body 3, and holes 4 and 5 are formed on two side surfaces of the lid 2 and the main body 3 which face each other. In the lid body 2, the hole portion 4 is formed in the substantially central portion of the side surface, and in the main body 3, the hole portion 5 is formed near the rear end of the side surface. The two protrusions 12 of the rotary holder 6 are fitted into the holes 4 and 5, respectively. As a result, the lid body 2 and the main body 3 are connected by the rotary holder 6, and the lid body 2 and the main body 3 are relatively rotatable with respect to the rotary holder 6, and the lid body 2 is It is possible to rotate and move from the position where the upper surface is covered to the position where it contacts the lower surface of the main body 3, which is indicated by the two-dot chain line in the figure.

FIGS. 2A to 2C are a front view, a bottom view and a rear view of the rotary holder used in the rotary accessory case. The rotation holder 6 is integrally molded by a known resin molding technique using a nylon resin or the like selected on the condition that it has sufficient strength and elasticity. The rotary holder 6 is composed of a base portion 11 and a protruding portion 12 that vertically protrudes from two locations on the back surface of the base portion 11 that are separated by a predetermined distance. This predetermined distance is equal to the distance between the hole 5 of the main body 3 and the hole 4 of the lid 2 at the position covering the upper surface of the main body 3 in the rotary accessory case 1. The base portion 11 is formed in a thin plate shape in order to minimize the amount of protrusion from the side surface of the rotary accessory case 1, and the front surface thereof is provided with a decorative pattern in consideration of aesthetics. This pattern is formed at the same time as the outer shapes of the base portion 11 and the protruding portion 12 during resin molding.

The protruding portion 12 is composed of a large diameter portion 12a having a hemispherical shape on the tip side and a small diameter portion 12b on the base portion 11 side, and a slit 13 is formed between the tip and the middle of the small diameter portion 12b. There is. The length L of the small diameter portion 12b is equal to or slightly longer than the wall thickness of the lid body 2 and the main body 3. The small-diameter portion 12b is formed in a taper shape that is thin on the tip side and thick on the base 11 side. As will be described later, the holes 4 and 5 of the lid 2 and the main body 3 are also wide on the outside and narrow on the inside. The small diameter portion 12b has an outer diameter slightly smaller than the inner diameters of the holes 4 and 5. On the other hand, the maximum diameter of the large diameter portion 12a is smaller than the inner diameter of the outside of the holes 4 and 5 and larger than the inner diameter of the inside thereof. Therefore, the stepped portion 12c is formed at the joining portion between the large diameter portion 12a and the small diameter portion 12b. The width of the slit 13 is such that, when the large diameter portions 12 a located on both sides of the slit 13 are deformed to the slit 13 side, the maximum diameter of the large diameter portion 12 a becomes smaller than the inner diameters of the insides of the holes 4 and 5. Has been to a degree.

FIG. 3 is a cross-sectional view of a main part showing a state in which the rotary holder is attached to the lid body and the main body in the rotary accessory case. When the rotary holder 6 is attached to the lid 2 and the main body 3, first, the protrusion 12 of the rotary holder 6 is attached to the holes 4 and 5 of the lid 2 and the main body 3 as shown in FIG. Then, the base portion 11 of the rotary holder 6 is pressed against the lid body 2 and the main body 3 side so that the protrusion 12 fits into the holes 4 and 5. As a result, the semispherical tip of the protrusion 12 is fitted into the holes 4 and 5 as shown in FIG. Further, when the base portion 11 is continuously pressed toward the lid body 2 and the main body 3, the large diameter portion 12a of the protrusion 12 comes into contact with the inner peripheral surfaces of the holes 4 and 5, as shown in FIG. The inner peripheral surfaces of the holes 4 and 5 are pressed to elastically deform toward the slit 13.

Due to this deformation, the outer diameter of the large diameter portion 12a matches the inner diameter of the inside of the holes 4 and 5, and by continuing to press the base portion 11, the large diameter portion 12a is shown in FIG. Thus, it is exposed inside the lid body 2 and the main body 3. The large diameter portion 12a exposed to the inside of the lid 2 and the main body 3 is released from the pressure by the inner peripheral surfaces of the holes 4 and 5, and is restored to the original size and shape by the elastic force. As a result, the maximum diameter of the large diameter portion 12a becomes larger than the inner diameter of the inside of the holes 4 and 5, and the inner edge of the holes 4 and 5 has a step portion between the large diameter portion 12a and the small diameter portion 12b. Contact 12c. Due to this abutment, the protruding portion 12 does not fall out of the holes 4 and 5.

As described above, according to this embodiment, when the rotation holder 6 is attached to the lid body 2 and the main body 3, the protrusion 12 of the rotation holder 6 is attached to the holes 4 of the lid body 2 and the body 3. It can be performed very easily only by pressing the base 11 against the lid 2 and the main body 3 side after facing to 5, and it does not require the use of a dedicated working machine or props or technical skill, The working time can be shortened, and the cost of the rotary small case can be significantly reduced in combination with the reduction in the number of parts. In addition, since the attachment state of the rotation holding tool 6 can be homogenized, there will be no trouble in rotation and will not fall off after attachment. Further, the metal part is not exposed inside the small case 1, and the stored items are not damaged.
