Description

[Detailed Description of the Invention] The present invention relates to flip-flops that have slanted through holes in the sandal body to facilitate walking in water and ensure safety while walking.

When walking underwater while wearing flip-flops, water pressure is applied to the sandals, making it difficult to walk underwater. In order to reduce water resistance at this time, a sandal base plate having a large number of perpendicular through holes is known as, for example, Japanese Utility Model Application Publication No. 13744/1983. However, if you step on a foreign object such as a shell or piece of wood while wearing flip-flops with this configuration and walking on the shore or in the sea, the foreign object will easily pass through the hole in the body and touch the sole of your foot. There was a risk of injury.

In addition, the sandals described above have a sheet material with slits on the upper surface of each through hole, but when a person steps on a thin shell or tree branch, it passes through the inside of the through hole and passes through the sheet material upwards, causing injury to the sole of the foot. Moreover, since the upper surface of each through hole is covered with the sheet material, water does not easily pass through, and walking in water is subject to water pressure just like in the past, making it extremely difficult to walk.
Sandals can come off your feet and be washed away.

This invention was created in view of the above circumstances, and it makes walking easier by making it less susceptible to water resistance when walking underwater, and also makes it safer to avoid injuring your feet even if you step on foreign objects such as shells or pieces of wood while walking. The purpose is to provide flip-flops with guaranteed sex. An embodiment of the present invention will be described below with reference to the drawings.

Drawings 1 to 3 show one embodiment of the flip-flop sandals of the present invention, in which Fig. 1 is a plan view, Fig. 2 is a bottom view, and Fig. 3 is a longitudinal section along Fig. 1 A-A. It is a front view.

In the figure, 1 is a sandal body on which the user's feet are placed. The main body 1 is made of a material having appropriate elasticity and strength, such as synthetic resin or rubber.

The sandal main body 1 is provided with through holes 4, 4, . . . that penetrate from the upper surface 2 to the lower surface 3. Each through hole 4 is formed non-perpendicularly to the upper surface 2 to the lower surface 3, and is formed in a linearly inclined shape here. Although the inclination angle of the through-hole 4 is not particularly limited, it is formed so that the opening position of the through-hole in the upper surface 2 and the opening position of the through-hole in the lower surface 3 do not overlap with respect to the vertical direction of the sandal body 1, and at least The opening position is set so that the other opening position cannot be seen through from one opening position when viewed from the above-mentioned vertical direction.

In the illustrated embodiment, an annular protrusion 5 is formed on the opening edge of the upper surface 2 of the sandal body 1 through holes 4, 4...
is formed.

6 is a thong for attaching the foot to the sandal body 1.

The operation of the flip-flop with the above structure will be explained below.

Place your feet on the top surface 2 of the flip-flop body 1,
When walking in water with the toe attached to the thong 6, the sandal main body 1 experiences water resistance as the foot moves up and down, but the plurality of through holes 4, 4... provided in the main body 1... allows water to pass through, so water resistance is drastically reduced.

In addition, even if you step on a foreign object such as a shell or a piece of wood while wearing the above-mentioned condition, the through hole 4 provided in the sandal body 1 does not penetrate at least vertically, so during normal walking, the foreign object will be caught on the inner wall of the through hole and fall onto the foot. never reach it.

The protrusion 5 provided on the opening edge of the upper surface 2 of the through hole 4 of the sandal body 1 prevents the foot from slipping when walking underwater, and also ensures breathability of the sole of the foot on land or on a sandy beach, improving walkability. enhance

In this embodiment, the inclination angle of the through hole 4 formed in the sandal body 1 is approximately 45 degrees, but this inclination angle may be determined by taking into account the thickness of the sandal body and the diameter of the through hole. If it is thick, it can easily be left upright.

As described above, according to the present invention, a through hole is formed that slopes from the top surface to the bottom surface of the sandal body,
Since the opening positions of the upper and lower surfaces are shifted, it is possible to reduce the water resistance experienced when walking underwater, and there is no danger of foreign objects such as shells or pieces of wood reaching your feet even if you step on them, so you can walk underwater. This can be done easily and safely, and the sandals will not come off the feet and be washed away when walking underwater. Therefore, it can be used not only when walking in the water, but also when walking on land such as on a rocky shore, as it will not injure the soles of the feet.
It has high practical value.

In addition, the through holes do not have to be cylindrical, but can have various diaphragm-like cross-sectional shapes, making it possible to create visually interesting products.
