(57) [Summary] [Purpose] The purpose is to protect the mounting part of the armrest pipe on the back of the back of the folding swing. [Structure] An introduction groove 8 having a diameter smaller than that of the armrest pipe 2 is provided at a diametrical direction or at an edge portion of a facing side of a cover main body 7 having a cup-shaped cross section which covers the mounting portion 6 of the armrest pipe 2 of the backrest 5, A shaft hole 9 into which the armrest pipe 2 is rotatably fitted is formed in communication with the introduction groove 8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cover for protecting a mounting portion of a U-shaped bent armrest pipe in a folding swing for an infant to a backrest of a seat.

[0002]

[Prior art]

 In general, swings for infants are usually foldable so that they can be transported and stored conveniently, and both ends are foldable in a U shape with the swinging body of the swing attached to the swingable body. The middle part of the armrest pipe is rotatably attached to the back of the seat back so that the seat can be folded.

For this reason, in the conventional swing for infants, the pivotable attachment of the armrest pipe to the back of the backrest prevents the risk of accidental disengagement and secures the safety. It was usual to use a metal fastener or the like as an auxiliary for the part.

However, although the auxiliary use of metal fasteners and the like is advantageous for securely attaching the armrest pipe to the back of the backrest, infants who actually use the swing and the handling of the swing. For a person, there is a risk that the fingers or the like may be damaged, and the assisting device has a drawback that it is directly visible.

[0005]

[Problems to be solved by the device]

 The conventional attachment of the swing for infants to the back of the back of the armrest pipe not only hinders safety, but also has a problem in design.

[0006]

[Means for Solving the Problems]

 The present invention has a cover main body having a cup-shaped cross section for covering the mounting portion of an armrest pipe of a backrest, and an introduction groove smaller than the diameter of the armrest pipe provided in the diametrical direction of the cover main body or at the edge of the opposite side. , And an axial hole which is formed so as to communicate with the introduction groove and into which the armrest pipe is rotatably fitted.

Further, it is preferable that the cover body is made of a synthetic resin material.

[0008]

[Action]

 Then, the U-shaped middle portion of the armrest pipe is rotatably attached to the back of the backrest, and the cover body is firmly attached to the armrest pipes on both sides of this attachment portion through the introduction groove to the shaft hole. Mounting, the entire back of the backrest to the armrest pipe is covered with a cup-shaped cover body.

At this time, the state of attachment of the cover body to the armrest pipe is maintained by the introduction groove smaller than the diameter of the armrest pipe, and the cover is rotatable with respect to the armrest pipe by the shaft hole.

Further, since the cover main body is made of the synthetic resin material, even if the introduction groove is smaller than the diameter of the armrest pipe, the cover body can be easily fitted by simply pushing. .

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 is a pair of swinging main bodies whose upper end portions are swingably mounted and suspended in parallel, and an armrest bent in a U shape. Both ends of the pipe 2 are rotatably mounted on the swinging main body 1 respectively.

Reference numeral 4 denotes a seat plate which is rotatably attached to the swing main body 1 below the shaft attachment portion 3 of the armrest pipe 2 so as to be rotatable on both sides of the swing main body 1. The backrest 5 is rotatable on the rear edge thereof. The mounting portion 6 is formed on the rear surface of the armrest pipe 2 so as to rotatably support the U-shaped intermediate portion of the armrest pipe 2.

Reference numeral 7 denotes a cover main body having a cup-shaped cross section which covers the mounting portion 6 of the armrest pipe 2 on the back surface of the backrest 5, and is formed in a hemispherical shape with a synthetic resin material, and the armrest has a diametrical edge. An introduction groove 8 having a diameter smaller than that of the pipe 2 is provided, and a shaft hole 9 into which the armrest pipe 2 is rotatably fitted is formed in the introduction groove 8 so as to communicate therewith.

In the embodiment shown in the drawings, the cover main body 7 is formed in a hemispherical shape, but it has a cup-shaped cross section in which the mounting portion 6 of the armrest pipe 2 is covered, and the armrest pipe is provided at the edge of the opposite side. Needless to say, it may have a shape other than the hemispherical shape, for example, a box shape, as long as it has an introduction groove smaller than the diameter and a shaft hole communicating with the introduction groove.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it is possible to completely cover the mounting portion of the armrest pipe on the back of the backrest, such as the infants who actually use the swing and the fingers of the handle of the Blanco. There is no danger of damaging the.

Moreover, since the mounting portion of the armrest pipe on the back of the backrest is completely covered, the design is also good.

Further, since the cover body is made of a synthetic resin material, it can be manufactured inexpensively and easily, and the cover body can be attached to the armrest pipe very easily.
