Description

[Detailed description of the invention] * Industrial application field The present invention relates to footwear for infants and the like that makes a whistle sound when walking.

* Conventional technology Footwear that makes a whistle sound when walking has been used for a long time. These devices form an air passage within the heel of the footwear, the inner end of the air passage facing the synthetic resin foam material surrounded by the air to prevent air from leaking to the outside, and the outer end of the air passage facing the heel of the footwear. It opens on the outside, and a flute is fitted into the open end from the outside.

* Problems that the invention aims to solve However, in conventional footwear such as the one mentioned above, one end of the whistle is exposed to the outside, so there is a risk that the whistle may pop out due to pressure during use or be pulled out at the store. There was also a problem where water got into the whistle and the whistle stopped playing.

The present invention attempts to solve the above problems by installing the whistle inside the heel part.

*Means for solving the problem Code 1 is the core plate. On the core plate 1 is a flexible open-cell synthetic resin foam material 2 with a large expansion ratio.
(e.g., polyurethane foam), and on the synthetic resin foam material 2, a flexible open-cell or single-cell synthetic resin foam material 3 (e.g., sponge) with a smaller expansion ratio than the synthetic resin foam material 2 is placed. A sheet 4 made of vinyl or the like is pasted on the outer surface of the synthetic resin foam material 3. That is, the synthetic resin foam material 2 is completely surrounded by the core material 1 and the sheet 4, so that air does not leak to the outside. Further, a ventilation passage 5 is formed in the heel part, the inner end of the ventilation passage 5 faces the synthetic resin foam material through a through hole 6 bored in the core plate 1, and the outer end of the ventilation passage 5 is formed in the heel part. open to the outside.

Therefore, in the present invention, a blocking plate 8 having a flute support hole 7 is provided upright in the middle of the ventilation path 5 in the heel part, and a pair of fins 9,
A whistle 10 equipped with a whistle 9 is fitted. These fins 9, 9 serve to prevent air leakage and to fix the whistle 10. Further, the ventilation passage 5 is opened to the outside of the heel portion by a plurality of small holes 11, 11, . . . . In the illustrated embodiment, the ventilation channels 5 are connected to the core plate 1.
and a hard heel member 12, and the heel member 12 is made of a flexible bottom 1 made of sponge or the like.
3, but the heel member and the bottom portion may be formed integrally. Further, the whistle support hole 7 of the blocking plate 8 may be formed by cutting out the upper edge of the blocking plate 8 as shown in FIG. may be set. 14 is a reinforcing portion.

* Effect: When the user presses the heel part while walking, the synthetic resin foam material 2 is compressed, and the air contained in the foam material 2 is pushed out from the foam material 2 and vented through the through holes 6 of the core material 1. After entering the channel 5 and passing through the whistle 10 and sounding the whistle 10, it exits through each small hole 11. Further, when the user releases the pressure on the heel part, the synthetic resin foam material 2 expands, and air passes through the flute 10 from the ventilation path 5 to the synthetic resin foam material 2.
sucked inside.

*Effects of the invention As explained above, in this invention, the whistle is installed inside the heel, so there is no risk of the whistle popping out due to pressure during use or being pulled out at the store, and there is no risk of the whistle being exposed to water. This also solves the problem of the whistle not sounding when the whistle is turned on. Furthermore, since the air passage is open to the outside through a plurality of small holes, water does not enter the air passage.

Claims (1)

[Claims for Utility Model Registration] A ventilation passage 5 is formed in the heel part, and the inner end of the ventilation passage faces the synthetic resin foam material 2 surrounded to prevent air from leaking to the outside. In footwear in which the end is opened to the outside of the heel part and a whistle 10 is attached to the ventilation passage, a blocking plate 8 equipped with a whistle support hole 7 is erected in the middle of the ventilation passage 5 in the heel part, and the whistle is A footwear characterized in that a whistle 10 having a pair of fins 9 is fitted into the support hole, and the ventilation passage 5 is opened to the outside of the heel part by a plurality of small holes 11.
