Description

In-line skates {In-line skate}

The present invention relates to inline skates, and more particularly, to an inline skate that is not affected by the impact from the outside by increasing the rigidity of the frame.

In-line skates are skates with wheels mounted in-line unlike traditional roller skates. Previously known as roller blades, roller blades are representative of in-line skates. The company's official sports name is inline skating.

The advantage of inline skating is that even beginners who practice shorter periods than other sports can enjoy it easily, feel the thrill of cutting wind, and aerobic exercise.

Conventional inline skates basically include a boot into which a user's foot is inserted, a cuff and a chassis surrounding the boot, a wheel having a driving force, and a frame mounted on the chassis to support the wheel.

In the conventional frame mounted on an inline skate, a pair of frames having the same shape are interconnected at one end, a connection portion formed at one end is mounted to the chassis, and a plurality of wheels are mounted at the other end via a bearing.

The frame should be strong enough to walk the user in striking state while wearing inline skates, and should be able to perform smooth movements by absorbing the impact so as not to apply excessive force to the user's body.

These frames are usually made of synthetic resin, which is made of aluminum in order to increase hardness and deliver more power to skates, but it is difficult to be used by general users because it has a disadvantage that it is expensive compared to synthetic resin. There is a problem.

In addition, in-line skating is a movement in which a lot of sweat is discharged from the whole body, but sweat evaporation can be easily performed in other areas, but a foot that is further surrounded by boots is more difficult to evaporate sweat, and the user feels stuffy, and smells bad. There is a problem that can cause diseases such as athlete's foot.

In order to solve such a problem, there is also provided a skate formed with a vent (vent) in the front of the boot, there is a problem that it is difficult to expect efficient ventilation because the air introduced through the vent is difficult to spread in the boot.

Therefore, the present invention is to solve such a conventional problem, the object of the present invention is to provide an inline skate that is less affected by external impact by increasing the rigidity by forming a frame in a double layer.

Another object of the present invention is to provide an in-line skate in which efficient ventilation is formed by forming an air vent in the bottom of the boot.

Still other objects and features of the present invention will be more clearly understood through the preferred embodiments described below.

1 is an exploded perspective view showing an inline skate according to the present invention.

According to the present invention, a boot, a chassis fixed to the outside of the bottom of the boot, a pair of frames having the same shape are integrally formed so as to face each other via a connecting portion, the wheel frame is connected to the chassis, a pair of frames Including a drive wheel rotatably mounted between, a pair of frames are each provided in inline skates, characterized in that the double fold has a large rigidity.

Preferably, the chassis may have a stepped portion in the middle of the longitudinal direction, the first vent may be formed in the step toward the front, and the second vent may be formed in communication with the first vent on the bottom of the boot.

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

1 is an exploded perspective view showing an inline skate according to the present invention.

It looks at the basic configuration of the inline skate according to the present invention.

The boot 10 is a shoe part into which the user's foot is inserted, and therefore, breathability, support, and comfort should be provided. Therefore, various materials such as mesh and leather are applied, and design aspects should be considered to appeal to the young generation.

In addition, the upper part of the ankle wrap around the neck, the neck is designed to have a long boots 10 is excellent stability and excellent stability, the neck is designed for short boots 10 is relatively stable, but excellent in activity.

In addition, the boot 10 further includes a tongue surrounding the foot, and a buckle and a shoelace and a strap that tighten the ankle, but a detailed description thereof will be omitted.

The cuff (not shown) surrounds a part of the front, side and rear of the boot 10, can be connected to the chassis 20 on one side, and boots that provide elasticity with the role of holding the ankle to provide comfort and stability It can be called the outer shell of (10).

The chassis 20 is fixed to the outside of the bottom of the boot 10 to connect the boot 10 and the wheel frame 30, in the case of soft boots, the chassis 20 and the cuff are separated, the movement of the ankle is However, in the case of hard boots, the chassis 20 and the cuff are integrally formed, which is relatively inconvenient compared to the soft boots.

The wheel frame 30 is one end is mounted to the chassis 20, the other end can be referred to as the pillar of the inline skate to which the drive wheel 40 is mounted, usually made of synthetic resin, but also made of aluminum to increase the hardness .

The driving wheel 40 is interposed between the pair of frames 32, rotatably mounted in the wheel mounting groove 38 via a bearing (not shown), and usually four driving wheels 40 are mounted. Depending on the application, three or five may be installed.

The diameter of the drive wheel 40 is usually expressed in mm units, the larger the diameter, the faster the speed, the smaller the diameter, the better the stability and controllability, but the slower the disadvantage. In addition, it is common to manufacture a synthetic resin of urethane or polyurethane which can control the hardness through chemical combination.

Looking in more detail with respect to the wheel frame 30 according to the present invention, since the wheel frame 30 serves to support the weight of the user, and to support the driving wheel 40 to the bearing, when selecting inline skates The choice must be made first.

The wheel frame 30 applied to the inline skate according to the present invention is integrally formed such that a pair of frames 32 having the same shape are opposed to each other via the connection part 34, and the connection part 34 has a chassis mounting groove. 36 is formed and firmly mounted to the chassis 20 by using a bolted connection or the like. In addition, a wheel mounting groove 38 for mounting a plurality of driving wheels 40 is formed at the other end not mounted to the chassis 20.

As shown, the portion in which the driving wheel 40 of the wheel frame 30 according to the preferred embodiment of the present invention is mounted is formed in a wave shape in consideration of a design side, and a pair of frames to improve rigidity 32 each consists of a double ply.

Looking at the wheel frame 30 in more detail, the wheel frame 30 is classified into polyurethane, nylon, carbon, composite, aluminum according to the material used in manufacturing.

Wheel frame 30 made of polyurethane and nylon synthetic resin is used because it is low cost, the durability against heat is weak, but the strength by impact is high.

The carbon wheel frame 30 is similar in price to the wheel frame 30 made of polyurethane and nylon synthetic resin, and has high strength against bending, but weakness due to impact.

The composite wheel frame 30 has a higher strength for supporting force and bending than aluminum, but the strength of the composite wheel frame 30 is inferior.

Aluminum wheel frame 30 is relatively expensive, the strength and bearing capacity of the impact is large, but the strength against bending is somewhat inferior to carbon or composite, there is a casting method and forging method.

As described above, there is provided a wheel frame 30 made by applying a variety of materials, there are advantages and disadvantages for each material, it is difficult to always use only a material with a high strength, conventionally formed of a single layer is a high strength material Even if using a lot of inadequate point, in the present invention can be solved by applying the wheel frame 30 is a pair of frames 32 are each formed in a double layer.

Inline skates according to the present invention are formed in the chassis 20 and the boot 10, respectively, in order to keep the foot in a comfortable state to form the first and second vents 24, 12 communicating with each other.

In the chassis 20 applied to the inline skate according to the present invention, it is preferable that a step 22 is formed at a middle portion in a longitudinal direction, and a first vent 34 facing forward is formed at the step 22.

In addition, it is preferable that the boots 10 applied to the inline skates according to the present invention have a second vent 12 formed in the middle portion of the bottom so as to communicate with the first vent 24.

As described above, the first vent hole 24 is not formed horizontally with the chassis 20, but is formed in the front direction in the step 22 formed in the chassis 20, so that the user wears inline skates and proceeds. As the wind generated can be easily sucked through the first vent 24, the sucked air can be evenly delivered to the inside of the shoe through the second vent (12).

In the above described with reference to a preferred embodiment of the present invention, various modifications or changes are possible without departing from the scope of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims of utility model registration.

As described above, the in-line skate according to the present invention has a large stiffness of the wheel frame is formed of a double fold, less affected by the impact from the outside, it can efficiently absorb the impact on the user's body It is possible to extend the service life and reduce the cost.

In addition, the air vent is formed in the center portion of the bottom of the boot and the chassis to easily inhale the air, so that the air flow into the boot and the distribution is efficient, so that it can maintain comfort even when worn for a long time. There is an effect that can be solved.
