Description

Single Edged Roller Sled

(Technology)

The present invention relates to a roller edge sled (Single Edged Roller Sled), and more particularly to a roller edge sled that allows you to enjoy the traditional outer blade sled on the flat.

(Background)

Before skating became popular as ice skating, traditional sleds were widely used, and these traditional sleds were classified into two-blade sleds with two blades in parallel, and single sleds with only one blade.

5 is a schematic perspective view of a traditional single blade sleigh. As shown, the traditional outer blade sled 100 has a flat footrest 110 on which both feet are raised, a single vertical support 120 attached to a predetermined height at the center of the bottom of the footrest 110, and a vertical support 120. It consists of a single blade 130 mounted on.

When riding the sleigh 100, with the two feet on both sides of the scaffold 110 around the vertical support 120, raise the sled 100 so that the vertical support 120 is upright, one vertical support 120 ) After grabbing the center of gravity with only a pole pole with a sharp tip at the bottom to wear the sled 100, the outer blade sled 100 is the same principle as the bicycle does not fall in the upright with only the outer blade (130) Will be run. Reference numeral 140 is a support for holding the user's posture safely.

Unlike the two-day sleds, the traditional one-day sleds, unlike the two-day sleds, in order to ride the sled 100, because it requires a considerable amount of skills to balance and balance in the state of standing up sleds, It required a lot of practice and learned the balance in the course of learning and riding the sleigh (100) had the advantage of exhibiting a variety of exercise effects, such as to increase the strength.

However, although the traditional single-day sled 100 has many advantages as a playground equipment, it is a pity that the ice that can ride the sled is practically lacking and is rarely used due to the supply of alternative rides such as roller skates. .

On the other hand, while roller skating and roller blades, such as rides and sports equipment that can ride on the flat rather than ice, are widely used, these are rollers of traditional skates and basically the way of riding is different from the traditional one-day sled 100 The feeling is also different.

An object of the present invention is to provide a roller-type outer blade sled that can be used on a flat surface, so that the traditional outer blade sled that is practically rarely used due to lack of ice, etc. can be freely enjoyed without regard to a place.

According to the present invention, there is provided a roller type uni sleigh in which a blade is replaced by a roller in a traditional ice uni sleigh.

According to the present invention, the foot of the user's feet are raised, a single vertical roller support vertically installed along the front and rear centerline of the bottom of the footrest, and a plurality of rollers rotatably mounted in a row on the vertical roller support Roller-rolled outer blade sleds are provided.

The plurality of rollers are composed of a front roller, a center roller, and a rear roller, wherein the distance between the front roller and the center roller is larger than the distance between the center roller and the rear roller, while the center roller is disposed at a lower position than the front roller. It is preferable in that it is possible to freely run and change directions.

Both sides of the scaffold by detachably mounted secondary rollers smaller in diameter than the rollers, it is preferable that beginners who are not familiar with balancing the sledges can be selectively mounted to easily ride the sledges.

In addition, the sled of the present invention is preferably equipped with an appropriate braking mechanism to be able to brake and decelerate the running sled.

Hereinafter, with reference to the accompanying drawings will be described in detail the roller-type blade sleigh according to the present invention. The following embodiments are merely illustrative of the roller-type outer blade sled according to the present invention, it is not intended to limit the scope of the present invention.

1 is a perspective view of an exemplary roller type outer blade sled according to the present invention, FIG. 2 is a plan view of FIG. 1 sled, FIG. 3 is a side view of FIG. 1 sled, and FIG. 4 is a bottom view of FIG. 1 sled.

As shown, the roller type sleigh 1 according to the present invention basically includes a footrest 10, a vertical roller support 20, and a plurality of rollers 30.

The footrest 10 is a plate-like member on which the user's feet are lifted, and is not particularly limited as long as the user can sit in a comfortable posture while holding the center of gravity. The same shape, the shape of the plane, the shape of the car, etc. can be made into a variety of children's favorite shape, the material may be plastic synthetic resin, wood and the like.

As shown in Fig. 2, the surface of the footrest 10 is formed with a concave groove 11 corresponding to the outline contour of the user's foot and / or by forming a concave-convex 12 having a high friction rate, whereby the foot can be naturally seated. It is desirable to prevent the slip of the foot while allowing the.

The vertical roller support 20 is assembled to the bottom of the footrest 10 along its longitudinal center line so that the footrest 10 and the vertical roller support 20 form a T-shape as a whole, and the height of the vertical roller support 20 is It is desirable to raise the sled 1 to some degree so that the sled 1 of the design can have the characteristics of the traditional unidirectional sledding.

The vertical roller support 20 is made of plastic synthetic resin, metal, or the like, and is appropriately assembled by various fastening mechanisms such as screws on the scaffold 10. When both the scaffold 10 and the vertical roller support 20 are made of plastic resin, the two members 10 and 20 may be integrally formed.

Vertical roller support 20 is rotatably mounted a plurality of rollers 30 to allow the sled 1 of the present invention to run on a flat. The rollers 30 are not particularly limited in number and mounting position, but the number and mounting position as shown in FIG. It is preferable to construct.

Specifically, the roller 30 is composed of three of the front roller 31, the center roller 32 and the rear roller 33, the distance between the front roller 31 and the center roller 32 is the center roller The center roller 32 is disposed slightly lower than the front roller 31 while being disposed to be larger than the distance between the 32 and the rear roller 33. Thus, depending on the user's center of gravity, the front roller 31 and the center roller 32 is in contact with the ground or the center roller 32 and the rear roller 33 is in contact with the ground so that the rear roller 33 and the front roller ( One of them is separated from the ground.

According to the arrangement of the rollers 30 as described above, when the user pushes the center of gravity slightly forward while driving, the front roller 31 and the center roller 32 touch the ground, and the rear roller 33 falls off the ground. Thus, safe driving is possible by the front roller 31 and the center roller 32 arranged at relatively wide intervals.

On the other hand, if the user slightly shifts the center of gravity toward the rear during the change of direction, the center roller 32 and the rear roller 33 touch the ground, and the front roller 31 falls off the ground, thereby placing them at relatively narrow intervals. By the centered roller 32 and the rear roller 33, the direction can be changed more easily in the direction intended by the user (direction to tilt the body).

Roller-type outer blade sled 1 according to the present invention, after raising two feet on the scaffold 10, after raising the sled (1) to the outer blade to balance, ride in a manner of moving forward while pushing the ground to the pole. At this time, when driving, the user should move the center of gravity slightly forward, so that the front roller 31 and the center roller 32 are in contact with the ground. With the center slightly biased to the rear, the center roller 32 and the rear roller 33 are inclined slightly in the desired direction in the state to be in contact with the ground.

The sled (1) of the present invention, like the traditional one-day sled, requires a considerable amount of skill to build and balance the sled on the outer edge, so that the beginners need to take the sled (1) of the present invention until they have a sense of balance. Can't handle it well. In other words, as soon as one of the two side ends of the footrest 10 will be in contact with the ground (sled fell down state), so it is necessary to repeatedly start up the sled again.

In order to alleviate the difficulties in dealing with the outer blade sleds 1 of the present invention, a pair of auxiliary rollers 40 that can be detachably attached and removed may be added to the sled 1 of the present invention. Can be.

For example, the auxiliary roller mounting holes 13 are formed on the bottom surfaces of both ends of the scaffold 10, and the auxiliary roller 40 having a smaller diameter than the rollers 30 is slightly higher than the rollers 30. By being configured to be detachably mounted on, it is possible for beginners who are not familiar with balancing unilateral sleds to selectively mount these auxiliary rollers 40 so that they can easily ride the sled 1.

The auxiliary roller 40 mounted on the footrest 10 floats without touching the ground during normal driving, but when the user loses balance and the footrest 10 is inclined to one side, the auxiliary roller 40 of the inclined side is moved. The sled (1) is first to catch the falling while touching the ground, the sled (1) is again balanced, so even beginners can easily ride the sled (1) of the present invention. The user who can ride the sleigh 1 skillfully removes the auxiliary roller 40 and rides the sleigh 1.

As a structure for mounting and separating the auxiliary roller 40 on the scaffold 10, conventional detachable structures may be applied as it is. For example, the auxiliary roller mounting hole 13 of the scaffold 10 forms a structure such as an insert or a slit, and forms a structure such as an insertion protrusion or an insertion plate corresponding to the support 41 of the auxiliary roller 40. By inserting the insertion protrusion or the insertion plate into the insertion slot or the slit, the auxiliary roller 40 can be detachably assembled to the footrest 10. In order to maintain the assembly state of the auxiliary roller 40, a locking composition such as a fixing pin or a locking jaw may be applied.

The sled 1 of the present invention is preferably equipped with a braking mechanism 50 that applies a braking force as necessary. As an example of the braking mechanism 50, the braking piece 51 made of rubber or plastic resin having a considerable strength and a high friction rate as shown in the figure is projected and attached to the right side of the rear roller 33 to friction with the ground. Can be used to provide a braking force.

In the case of using the braking piece 51 as the braking mechanism 50, the mounting height of the braking piece 51, when the user shifts the center of gravity slightly to the rear for the above-mentioned direction change, the braking piece 51 is placed on the ground. When not in contact with the center of gravity more rearwards, the braking piece (51) is to the height to reach the ground. According to the configuration of the braking piece 51 as described above, if the user properly moves the center of gravity, the sled 1 can be braked when necessary.

The pole for providing driving force to the sled 1 of the present invention can be used as a pole with a high friction rubber nib suitable for use on asphalt or road.

According to the roller-type single blade sled according to the present invention described above, it provides an effect such that the traditional single blade sled that is practically rarely used due to lack of ice, etc. can be freely enjoyed on the plain without being bound to a place. By distributing healthy play equipment to children who are less likely to exercise, they can increase their strength and balance.
