Description

[Detailed description of the invention] [Field of industrial application] The invention relates to sandals with fixed underwater fins, and more specifically, when performing skiuba diving, conventional marine boots are integrated with underwater fins. This invention relates to a device that can be used in combination with

[Prior Art] As is well known, many people enjoy skiuba diving, which involves diving under water such as the sea and swimming underwater.

When performing scuba diving, a diver must wear underwater fins on his or her feet.

The above-mentioned underwater fins have a foot insert that is attached to the foot, and there are boot types that have a rear wall not only at the toes but also at the heel, and those that do not have a rear wall at the heel and are fixed with a band. There are free types (for example, Utility Model No. 35-21255).

Divers wear the underwater fins on their feet when diving at appropriate depths, and they generally wear them on their bare feet. However, when the diver is barefoot like this,
When wearing underwater fins, they fit well, but before you put them on, there are rocks, shells, etc. while walking from the beach to the diving site, so they may cause pain or injury when walking. It was hot.
Therefore, until the destination is reached, marine boots that are worn barefoot are conventionally used.

The above-mentioned marine boots are made of a lightweight, flexible material that is water-resistant, such as neoprene sponge rubber. Since the feet are protected by wearing them, the feet will not be hurt or injured by rocks or the like when walking. However, the marine boots themselves fit comfortably on the feet and allow for easy walking on the beach.

The above-mentioned marine boots and underwater fins are used according to their respective purposes, and divers usually wear one of the above-mentioned marine boots.
At the diving destination, one changes to the other underwater fins.

[The problem that the idea attempts to solve]

According to the above, there is an advantage that the marine boots can protect the feet until the diving destination where the underwater fins are worn. However, it had some problems in the following points.

In other words, marine boots and underwater fins are completely different objects depending on the individual purpose, so when you are diving at a certain depth, you take off your marine boots, insert your feet into the foot holder of the underwater fin, and The problem is that the shoes must be fixed with a band, which makes changing the shoes cumbersome. However, since marine boots are tightly fitted to the feet, it is difficult to take them off, and depending on the location, beginners may not be able to change them.

Therefore, it has been considered to attach the underwater fins while wearing the marine boots, but in reality, the marine boots are not completely fixed to the underwater fins due to their purpose and material. Then, there is no feeling of fitting, and the underwater fins tend to come off during use, which is dangerous. Furthermore, since the marine boots and underwater fins are not completely fixed, there is a possibility that the heel portion of the marine boots may be worn out by the tightening band of the underwater fins. Therefore, it has been desired to develop a means that can combine both of these elements in an integral manner to allow underwater fins to be used safely as before. However, it has been proposed that the underwater fin be composed of a flexible fin part and a rigid mounting part, so that diver boots (marine shoes) or tennis shoes can be fixed to the top of the mounting part ( Japanese Patent Publication No. 59-88168
In this case, the bottom part should be thicker than other parts to enable connection with the above-mentioned mounting part, and should have enough rigidity to be able to be hooked to the connecting means provided on the mounting part side of the underwater fin. This negates the advantages of marine boots.

The present invention was made in view of the problems of the conventional technology, and its purpose is to take advantage of the advantages of conventional marine boots and their purpose, such as protecting the feet, and to develop the new technology. Above,
The objective is to provide a means for integrally connecting the marine boots to underwater fins while wearing the marine boots at a diving destination.

[Means to solve the problem]

In order to achieve the above object, the present invention has the following technical means.

That is, to explain this using the reference numerals in the attached drawings corresponding to the embodiments, the present invention has an underwater fin 9.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As is well known, many people enjoy skiuba diving, which involves diving under water such as the ocean and swimming underwater. As is well known, in skiuba diving,
An underwater fin 9 is used for diving and swimming underwater.

Underwater fins are used by attaching the foot pocket 10 to one's own foot. There is a free type that does not have a rear wall and is fixed with a band. Divers need to wear the underwater fins 9 when scuba diving, but they also need to wear the underwater fins 9 when walking to a diving destination at a certain depth.
He is wearing Marine Boots 8.

The present applicant provides the underwater fin fixed sandal 1 of the present invention described below as a means for integrally connecting the above-mentioned conventional free type underwater fins 9 and marine boots 8.
FIGS. 1 and 2 show specific embodiments of the present invention.

That is, as shown in FIG. 1, the underwater fin fixed sandal 1 of the present invention has a foot insert 4 having a toe portion 4A and a heel portion 4B integrally formed on a deck 2. . The deck 2 above is
It is composed of a lower deck 2B made of a rubber member and an upper deck 2A made of a flexible sheet such as closed-cell urethane foam or vinyl chloride.
Further, a strength member 3 made of glass fiber or the like is disposed between the upper and lower decks 2A and 2B over the entire surface of the deck 2, thereby imparting rigidity to the deck 2. In the above structure of the deck 2, the underwater fin fixed sandals 1 can be inserted into the free type foot pockets 10 of the underwater fins 9 in just the right amount.

Further, the above-mentioned marine boots 8 can be attached to the foot insertion part 4, and a cushion part 7 made of neoprene sponge rubber is disposed in a band shape from the toe part 4A, and a hook-and-loop fastener 6 is arranged approximately in the center of the cushion part 7.
Stop bands 5A and 5B having A and 6B are formed. The retaining bands 5A, 5B are arranged by adjusting the hook-and-loop fasteners 6A, 6B on the cushion pads 7 which are inevitably located at the instep of the diver's feet when the marine boots 8 are attached to the foot inserts 4. It is something that can be stopped.

Further, a locking means 11 is provided on the heel portion 4B of the foot insert 4 and the underwater fin 9 for removably fixing them to each other. That is, a lock recess 12 and a lock piece 13 are formed on the heel 4B side of the foot insert 4, and a lock lever 14 is attached to the underwater fin 9 side. The lock lever 14 has a lock tip 15 that fits into the lock recess 12 and a lock bar 16 that engages the lock piece 13, and is connected to a lock lever arm 17 extending from the underwater fin 9.

As shown in FIG. 3, the lock lever arm 17 has its end inserted into a spring case 18 attached to the side wall 9A of the underwater fin 9.
A coiled spring 19 provided between a stopper 20 fixed to the end and the spring case 18 always biases the spring case in the closing direction. The urging force of the lock lever arm 17 allows these lock means 11 to be easily opened and closed.

However, conventionally, when walking to a diving destination at a certain depth while wearing underwater fins, a diver
As mentioned above, he is wearing marine boots.

The above-mentioned marine boots are effectively used as a means for divers to wear underwater fins on their bare feet. In other words, by wearing marine boots made of light and flexible material such as neoprene sponge rubber on bare feet, you can protect your feet while walking to your diving destination and prevent your feet from getting damaged by rocks, shells, etc. on the seashore. This is because you won't get any pain or injury, and you can wear them on your bare feet and walk easily on the beach or in the water.

However, as mentioned above, the marine boots themselves are excellent in practical use, but as mentioned above, it is difficult to take off the marine boots at the diving destination, insert your feet into the foot openings of the underwater fins, and secure them with a band. The task of changing shoes was troublesome.
However, since marine boots are meant to fit bare feet, it is even more difficult to take them off. Also, depending on the conditions of the diving destination, beginners may
Sometimes it is not possible to change marine boots. Therefore, it is considered to attach the underwater fins while wearing the marine boots, but realistically, due to their purpose and material, the marine boots cannot be completely fixed to the underwater fins even if they are secured with a fixing band. At the same time, there is a risk that the fixing band may damage the marine boots. Alternatively, it is conceivable to attach a locking means for fixation, but since marine boots are made of a flexible material for that purpose, it is impossible to attach them to the marine boots themselves. In addition, if marine boots are made of a material that can be attached to underwater fins, the original purpose of marine boots will not be utilized. Therefore, there has been a demand for the development of a means that takes advantage of the advantages of conventional marine boots and integrally combines both of them, allowing underwater fins to be used safely as before.

Therefore, the present applicant has solved all of the above conventional problems by providing the underwater fin fixed sandal 1 having the above structure. That is, to explain its specific usage, first, when skiuba diving, a diver wears marine boots 8 that are fitted to his feet as in the past, and goes to a diving destination at a certain depth.

Then, at the destination, first wear the marine boots 8 above.
While wearing the sandals, insert the feet into the foot openings 4 of the underwater fin fixed sandals 1. Then, the cushion part 7 connected to the toe part 4A is located on the instep of the foot, so the hook and loop fastener 6A,
6B and fix the stop bands 5A and 5B. Cushion pad 7 is made of a thick, elastic and flexible material (made of neoprene sponge rubber), so its elasticity allows it to be fixed more reliably. On the other hand, since the upper deck 2A of the deck 2 is made of a flexible sheet such as urethane foam or vinyl chloride, the upper deck 2A fits perfectly on the back of the foot. As a result, the underwater fin fixed sandal 1 is completely integrated with the foot wearing the marine boots 8.

Next, as shown in FIG. 2, the user puts his or her feet into the foot pockets 10 of the free-type underwater fins 9, and suitably inserts the deck 2 of the underwater fin fixed sandals 1. Finally, locking means 11 arranged on both sides
to securely fix it to the underwater fin 9. in this case,
First, by simply raising the lock lever 14, the lock tip 15 is fitted into the lock recess 12, and the lock bar 16 is engaged with the lock piece 13, so that it is securely fixed to the underwater fin 9. This lock lever 14 always has a spring 19 as shown in FIG.
The underwater fin fixing sandal 1 is biased in the closing direction, but the deck 2 that constitutes the underwater fin fixing sandal 1 is equipped with a strength member 3 for imparting rigidity.
Since it is provided over the entire surface, it will not bend due to biasing force, and therefore will not come off while swimming underwater.

In addition, the underwater fin fixing sandal 1 is securely fixed to the underwater fin 9 by the locking means 11, and the marine boots 8 attached to the foot insert 4 are integrally connected to the underwater fin, so that a comfortable fit is achieved. Yes, it is safe during use. Further, since the locking means 11 is provided between the heel portion 4B of the foot insert 4 and the underwater fin 9, there is no risk of wearing or damaging the marine boots.

In addition, when the lock lever 14 is lowered, the lock bar 16 comes off immediately, the lock is easily released, and the underwater fin fixed sandal 1 can be taken off. A diver can easily fix the heel portion 4B of the foot insert 4 of the underwater fin fixing sandal 1 and the underwater fin 9 to each other by simply moving the lock lever 14 of the locking means 11 up and down.

As described above, by using the underwater fin fixed sandals 1, the diver can effectively use the marine boots as before and easily put on the underwater fins 9 while wearing the marine boots at the diving destination. It is possible to carry out scuba diving.

Note that this underwater fin fixed sandal can also be worn while walking while being attached to marine boots.

In addition, the materials used for the deck, cushion parts, strength members, etc. of the underwater fin fixed sandals of the above-mentioned example of the present invention may be other materials as long as they have the same effect, and the locking means can also be easily and securely fixed. Make it safe.

[Effect of idea]

Since the present invention is configured as described above, it produces the following effects.

That is, divers can easily attach the underwater fin fixing sandals to their marine boots, and can easily attach the underwater fins and secure them with the locking means while wearing the marine boots, saving them the trouble of taking off conventional marine boots. Even beginners can easily install it.
However, as mentioned above, through underwater fin fixed sandals, marine boots and underwater fin fixed sandals,
Since both the underwater fin fixing sandals and the underwater fins are securely fixed, they will not come off during use, and the sandal has a secure fit, so it is safe during use. In addition, since marine boots are used in the conventional manner, they have various practical advantages, such as their original purpose of protecting divers' feet and making full use of the lightness of walking on the beach. has. In particular, the deck that makes up the underwater fin fixing sandals includes a strength member to provide rigidity, so it will not bend when fixed to the underwater fins, ensuring the integration of the underwater fins and the underwater fin fixing sandals. This ensures that the boots do not fall off during use, and since the top of the deck is made of a flexible sheet, it ensures a secure fit between the feet wearing marine boots and the foot inserts. These effects can significantly improve the integrity of the foot and underwater fin.

In the underwater fin fixed sandal of claim 2,
The advantage is that you can easily lock and secure the underwater fin fixing sandals and underwater fins by simply moving the lock lever up and down.
