Description

Technical Field [0001] The present invention relates to a manufacturing method of flippers including carbon fibers,

The present invention relates to a method for manufacturing a flippers including carbon fibers, and more particularly to a method for manufacturing flippers including carbon fibers produced by vacuum-forming carbon fibers and epoxy-impregnating the flak and the foot.

In general, according to the Registered Utility Model Registration No. 20-0342248 of the Registered Utility Model No. 20-0342248, the flippers are equipments to be worn in the marine leisure activities such as skin scuba diving or swimming, and in the state where the body is in the water , Which is a device for pushing the knee at a constant angle and simultaneously pushing the tip of the toe while pushing it up and down in order to propel it using the flippers.

Currently used skin scuba diving and swimming flippers are constructed so that they can be used uniformly without distinction between right foot and left foot.

According to the invention, there is provided a flippers for underwater leisure in accordance with Registration No. 20-0342248, the flippers being worn on the feet so as to generate a propelling force in the water, the flippers comprising a foot portion for covering the foot, And a foot accommodating portion composed of both side wall portions and a bottom portion integrally formed with the bottom wall portion and a foot claw portion.

As another conventional art, according to the swim shoe disclosed in Japanese Patent Application Laid-Open Publication No. 2003-0009647, an ankle protecting part formed in a foot shape with a stretchable material and capable of protecting an ankle is integrally formed And a sole portion fixed to the lower surface of the shoe portion by an adhesive so as to form the sole of the shoe portion and formed of a material having a predetermined strength and projecting a webbing portion for generating propulsion force in the forward direction of the shoe portion, Which is referred to as a swimming assistant shoe.

However, the conventional flippers are made of rubber and have a disadvantage that the flippers are heavy and the ankle joints are large and fatigue is high.

Accordingly, it is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a carbon fiber composite material which is free from ankle joints and has excellent carbon elasticity of a flippy plate, Neoprene foam rubber is added to the foot area of the foot to make the wearer feel comfortable to wear. Also, it is easy to combine with Velcro by forming a hole in each of the flippers and toes. The present invention provides a method for manufacturing a flippers.

The present invention relates to a method for manufacturing a flippers comprising carbon fibers, comprising the steps of: applying wax and a releasing agent to a mold for a flap 10 and a foot 20, respectively, followed by curing;

Two steps of laminating the carbon fibers on the mold surface of the flap 10 and the foot 20, respectively, and covering the vinyl;

(3) a step of heating and curing epoxy on top of the vinyl cover on the surface of the mold of the dorsal plate 10 and the instep 20 through the above two steps;

A fourth step of separating the flap 10 and the foot 20 manufactured through the three steps from the mold, respectively;

.

Accordingly, the present invention is characterized in that since carbon fiber is included throughout the product, the strength is large and light, so that the ankle joint is not burdened and the carbon elasticity is excellent, so that the speed is faster than the conventional flippers at the time of finishing, And a coupling hole is formed in each of the upper and lower legs, thereby achieving a remarkable effect that the coupling can be conveniently performed with the velcro.

The present invention relates to a method for manufacturing a flippy comprising carbon fibers, comprising the steps of: applying a wax and a releasing agent to a mold of a flippers (10) and an instep (20), respectively, followed by curing;

And a control unit.

In addition, the second step may further include a step of covering with vinyl and vacuum-pressing.

The hooks 11 and 21 formed on each of the flap 10 and the foot 20 manufactured through the fourth step are coupled to each other using the Velcro 30. [

The present invention will be described in detail with reference to the accompanying drawings. Fig. 3 is a perspective view of the flippers of the present invention, Fig. 4 is a photograph of the flippers of the present invention, Fig. 5 is a photograph of the flippers of the inventive gypsum, Fig. Picture of the instep.

The present invention first prepares the flippers and the foot mold.

The mold is made of metal such as aluminum.

Then, a mold release agent such as wax and silicone oil is uniformly applied to the flippers and the foot mold.

Then, it is cured at room temperature for 20 to 30 minutes.

The carbon fibers are then laminated on the flippers and the top mold surface, respectively, so that the carbon fibers are brought into close contact with the surface with care not to turn the blades.

And then vacuum-bonding the inner surface of the carbon fiber to the surface of the carbon fiber by putting the vinyl on the carbon fiber, putting the vacuum hose inside the vinyl, and sucking the inner air to be vacuumed by the vacuum pump .

Thereafter, the mixed liquid of the epoxy and the hardening material (epoxy hardening material) is passed through the above two steps, and then the upper and lower portions of the flipper plate 10 and the instep 20 covered with vinyl are impregnated with epoxy, Heat to 120-130 ° C in an oven.

At this time, the ratio of the epoxy to the hardener is proper to the ratio of 5 to 1 by weight.

Since the flap plate and the foot mold manufactured through the above steps can be separated from the mold and then abraded by friction on the foot area of the instep, respectively, the neoprene foam rubber, which is an elastic synthetic resin, So that they can be sensed and bonded to each other with an instant adhesive, cut the rim, and finish with sandpaper.

Thereafter, the engaging holes are pierced using a rotary saw blade on each of the flipper plate and the foot, and then the engaging holes are coupled to each other using the Velcro (30). Normally, each of the two holes is punched, and then the end of the velcro passes through one hole from top to bottom through another hole and then passes from bottom to top. The engagement hole conveniently forms a slot in the ankle direction from the tip of the foot. On the other hand, grooves are formed on both sides of the plate, so that the velcro is stably fixed even after it is joined, so that it does not slip back and forth.

At this time, combine to the top of the foot.

The plaid is formed in such a way that the webbing is formed at the end and the width becomes narrower from the tip of the foot to the ankle. The overall shape is a flippy shape, and the foot is formed by splitting the cylinder in half, especially on both sides. The lower surface of the adhesive plate is adhesively bonded to the upper surface of the plate by an epoxy bond adhesive.

As another example, a long hole for an adhesive plate may be punched in a front-rear direction at a play position corresponding to the foot-on adhesive plate, the end of the adhesive plate may be inserted, and then the outer surface may be bent to bond the top surface to the bottom surface of the plate with an instant adhesive. The length of the elongated hole for the adhesive plate is sufficiently larger than the length of the adhesive plate so that the adhesive plate can be adjusted in the longitudinal direction in the longitudinal direction of the adhesive plate so that the position of the legs above the label can be adjusted. If the foot length is a little longer or shorter, the part where the foot is located is appropriately adjusted.

The plaid can be glued neoprene foam rubber to the middle of the heel and soles with a glue for the purpose of non-slip.

Therefore, the present invention is characterized in that carbon fiber is contained throughout the product, so that the elasticity of the carbon is excellent because of its high strength and lightness, so that there is no problem in the ankle joint and the bonding hole is formed in each of the flippers and the foot during manufacture, It can be convenient.
