Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to marine boots for marine sports such as surfing, board sailing, diving, and sailing. The marine boots of this invention are also suitable for other water sports such as canoeing, mountain stream fishing, and shower climbing.

[Conventional technology]

Conventional marine boots have a sock-like structure in which an upper made of a water-resistant soft material such as neoprene rubber is bonded to a rubber sole. Neoprene rubber is a material that is highly insulating, water resistant, and easy to wear, and has recently become a preferred material for water sports shoes. Furthermore, for footwear with rubber pieces attached to the toe and heel parts, Utility Application No. 59-93580 and Utility Model No. 57-
No. 50882 and Utility Model Publication No. 51-153998 have been published.

[Problem that the invention attempts to solve]

However, conventional marine boots have the following problems. When water collected inside the marine boots, the feet slipped inside the boots, causing problems with mobility. In particular, there were cases in which the heel slipped inside the boot, making it difficult to keep it firmly in place, and the boot sometimes rotated. Neoprene rubber boots have elasticity in the material itself, allowing the feet to move freely from side to side. However, there were problems with lateral movement and lack of braking. Marine boots have a sock-like shape with long and thin ankles to prevent water from getting in. As a result, they were inconvenient to put on and take off, making them difficult to put on and take off. In addition, the structure of the above-mentioned Utility Application No. 59-93580 covers the toe and heel with a non-hard rubber sheet in order to prevent foot lacerations and to not hinder movement. The toe and heel cannot be fixed to the shoe, and in the configuration of Utility Model Publication No. 57-50882, the triangular attachment piece provided on the heel has a concave and convex wave shape. In addition, the triangular shape obstructs the expansion, contraction, and flexion movements of the ankle. Because it is not hard, the toe and heel cannot be fixed to the shoe, and the weight of the thick fins tends to create gaps in the sole of the shoe, making it easy for the toe and heel to slip. be.

[Means to solve the problem]

The present invention is a marine boot made of neoprene rubber, in which a hard part is provided at the counter part, and a tightening band is provided at the front of the instep, with a distance between the bent toes, and the front end is at the base of the toes. This fixes the heel and tip of the foot to the shoe and prevents the foot from slipping or shifting inside the shoe. The hard part is made of thick leather sewn to the heel part, or leather with a curved synthetic resin plate sandwiched between the heel parts, and has a grooved line at the upper part of the rear part with a height equal to or less than the bending point of the ankle. It is formed in such a way that it does not interfere with the expansion, contraction, and flexion of the Achilles tendon and ankle. In addition, in order to make it easier to put on and take off, to prevent water from entering, and to prevent the ankle part of the boot from bending when not worn, a zipper is provided on the side, and unevenness is formed on the inside of the zipper so that both pieces can be separated. A mating piece that is closed together and a presser piece that presses and closes this mating piece from inside are provided. These structural means provide a marine boot that is easy to put on and take off, has a fixed heel and toe, prevents the foot from slipping inside the shoe, has excellent mobility, and has improved waterproofness.

【Example】

Next, an embodiment of marine boots according to the present invention will be described based on the drawings. FIG. 1 is a side view of the marine boot, FIG. 2 is a perspective view, FIG. 6 is a partial sectional view of the hard part, and FIG. 7 is a rear view. Marine boots 1 consist of a rubber sole 2 and an upper 3 made of neoprene rubber (wet suit fabric), a hard part 4 is provided at the counter part, a tightening band 10 is provided on the upper 3, and a zipper 21 is provided on the side. It is something that The hard part 4 is formed by sewing relatively thick leather to the heel, or by sewing a leather 6 sandwiching a curved synthetic resin plate 5 to the heel. The hard part 4 is designed to have a size that allows at least the heel of the foot to be inserted and held therein, and small protrusion-like marks 40 are preferably provided at three locations as references for sewing positions. The hard part 4 is formed into a concave shape 8 at the upper part of the rear part with a height below the flexion point 7 of the ankle so as not to hinder the expansion and contraction of the Achilles tendon and the flexion of the ankle. When the heel is inserted into the hard part 4, the heel does not slip backwards within the boot and becomes well stabilized. The instep 3 is provided with a belt-shaped tightening band 10 in the front with a bending interval 9 between the toes, and its front end is located at the base of the toe, so that the instep of the foot can be attached to the left and right inside the boot. I try not to shift. As shown in FIGS. 1 and 2, one embodiment of the tightening band 10 is such that winding pieces 12 to which synthetic resin string loops 11 are attached are provided on both sides, and tongue pieces 13 protect the vape 3. It is configured to be tightened with a string 14. The tightening band 10 fixes the instep of the foot, and the hard part 4 fixes the heel, so the foot inside the boot is fixed at two places in the front, back, left and right. Other embodiments of the tightening band include one in which a rubber band 15 is attached to the instep as shown in FIG. 3, and one in which a space 16 is provided in the instep as shown in FIG.
with Velcro band 1 as shown in Figure 5.
8 and a mounting bracket 19 are provided. A zipper 21 is provided on the side surface, and matching pieces 22, 23 and a presser piece 24 are provided on the inside thereof. The mating pieces 22 and 23 form irregularities on each other and are closed by fitting them together, and the presser piece 24 further presses and closes the mating pieces 22 and 23 from the inside to prevent water from entering. . The zipper 21 makes it easier to put on and take off by opening it, and also prevents the ankle part 30 from bending in the middle even when the foot is not inserted (the material is soft, so without the zipper, it will bend in the middle and is not suitable for display). It also has a reinforcing effect. In addition, in FIG. 3, a rubber elastic part 25 is formed in the ankle part 30 to make it easier to put on and take off. The marine boots 1 according to the present invention are formed into a boot-like shape so that the neoprene rubber joint seams 20 are lined up on the front surface where there is less exercise load to prevent water from entering and to ensure durability. Since there are few sewn parts, manufacturing efficiency is good and durability is high.
