Abstract

PURPOSE: A skating shoe is provided to apply a camber for directly mounting a roller without a camber for mounting the roller to be inclined. CONSTITUTION: A skating shoe includes a frictional part(10) and a roller(20). The frictional part is placed along the outside of the lower side of a shoe. The roller is placed along the inside of the lower side of the shoe. In walking, the shoe is erected so that the frictional part and the roller can be in contact with the ground. In skating, the shoe is inclined so that only the roller can be in contact with the ground. Therefore, the shoe is capable of preparing for uneven wear in walking and additionally preventing a slip.

Description

Skater Shoes {A}

The present invention relates to skates and, more particularly, to skating shoes that can alternately walk and skate without using a mechanical configuration or special functional switching means.

Existing background art is Patent Registration No. 10-0940036 (2010.02.26) provided by the applicant of the present application and summarizing the registered patent,

A friction part disposed along the outer side of the bottom of the shoe; And rollers disposed along an inner side of a bottom of the shoe.

When walking, the inner edges of the rollers are not grounded, and the friction part and the outer edges of the rollers are respectively grounded,

In the skating so that the friction portion is not grounded, only the rollers are grounded,

The bottom of the roller is a skating shoe constructed by giving a positive camber facing towards the user side.

here,

The configuration in which the friction part is grounded to support the load on the outside while walking and at the same time the outer edge of the roller is grounded to support the load on the inside is a unique feature unique to the above patent.

In the registered patent, the phenomenon that only the outer edge of the roller is worn out due to the unique characteristics of the roller, is called 'walking single wear'.

The walking wear wear is not only a problem of endurance of the roller, but also a weakening of the bearing force due to the support point shift at the outer edge, so that the user who needs to maintain the center only on the roller during skating is difficult to maintain balance.

In general, considering that roller wear of the skate occurs during the running of the skating, the walking wear wear is a unique phenomenon only in the registered patent.

In addition, in the pushing operation for extending the foot to the side to apply a driving force during skating, a slip phenomenon in which the roller slides sideways may occur.

According to the present invention,

It is intended to provide a countermeasure against the walking wear wear. In addition, it is intended to prevent the slip phenomenon.

And another object of the present invention,

It is to have the effect of providing a camber while directly mounting the roller without providing a camber for tilting the roller.

In order to solve the above problems, the skating shoe of the present invention,

Shoes 4;

A friction part 10 disposed along an outer surface 4o of the shoe; And

And rollers 20 disposed along an inner bottom 4i of the shoe.

When walking, the shoe is immediately placed so that the inner edges 20e2 of the rollers are not grounded, and the friction portion and the outer edges of the rollers 20e1 are respectively grounded;

Tilting the shoe sideways when skating so that the friction portion is not grounded, and both the inner and outer edges of the rollers are grounded; In the above-described configuration, reference is made to FIGS. 1 and 3 or the bar described in the registered patent.

Here, it is important that at least one of the rollers is configured such that the outer diameter of the roller is larger than the central diameter.

As long as the outer edge keeps in contact with the ground during walking, the wear phenomenon itself that progresses to the outside of the roller cannot disappear. Therefore, it is necessary to adopt a structure that recognizes the walking wear and extends the countermeasure and the support function of the outer edge thereof. To do so, it is necessary to protrude the outer edges to delay the time that the outer edges disappear due to walking wear. As a result of the above-described structure, the endurance life of the whole roller is increased and the outside of the roller can extend its supporting function.

It is preferable to take a structure in which the outside of the roller protrudes as described above for all the rollers, but otherwise, at least one roller can take the above structure to maintain the supporting function.

In addition, at least one of the rollers may be configured by making the outer diameter of the roller larger than the inner diameter, as well as contrast with the walking wear and tear, even if the bearing is horizontally mounted without a positive camber, The diameter of the inner edges 20e1 and 20e2 has the effect of giving the positive camber.

According to the present invention,

As it can delay walking wear, it extends the durability of the entire roller, and the support function of the outer edge continues even after long-term use.

In addition, it is possible to reduce the slip phenomenon of the roller which may occur in the pushing operation.

The scope of the present invention includes other implementations of the technical idea of the present invention.

Various matters necessary to achieve the present invention, in other words, shoes (4); Friction part 10; Roller 20; For example, the matters related to each component, the arrangement between the components, and mutual organic relations overlap with those described in Patent No. 940036, which will be referred to.

Hereinafter, the specific implementation of the present invention will be described based on the roller 20 (roller, wheel, wheel) in particular with the accompanying drawings based on the above-mentioned bar solution.

As shown in FIG. 2A, the outer edge 20e1 of the roller 20 is larger in diameter than the center side 20m (do> dc). The shape can be achieved by forming the protrusion 21 along the circumference of the outer edge 20e1 or vice versa by forming the depression 22 recessed along the circumference of the center side 20m of the roller 20. . The protruding portion 21 and the recessed portion 22 is a relative concept, and if one is formed, the other is naturally formed. The formation includes joining and removing, for example, attaching a separate protrusion 21 to the roller 20 or removing the outer periphery of the center side 20m of the roller 20 to form the depression 22. can do. The center side 20m refers between the outer edge 20e1 and the inner edge 20e2.

The action of the roller 20 taking the form of FIG. 2A is shown in FIG. 2B, when the user applies a walking load to the outer edge 20e1 that is grounded when walking, the outer side may be caused by collision with the ground and friction. Only the edge 20e1 walks 5 'of the walking wear, and eventually the original support point e shifts. The support point (e`) shift of the registered roller shown in FIGS. 8A and 8B is larger than the support point (e``) shift of the roller of the present invention and is relatively close to the inner edge 20e2. As a result, the width of the roller 20 is narrowed, and accordingly, the skeletal function of the outer edge 20e1 decreases and is lost during skating.

In addition, the protrusion 21 may take the form of a rim formed along the circumference of the outer edge 20e1 as shown in FIG. 2C. And it can be formed by permanently attaching or detachable separate rim (21r) as shown in Figure 6C. The protrusion 21 formed in the shape of the rim continues to provide a support point approximate to the point shape as shown in FIGS. 8C and 8D, so that the shift phenomenon can be minimized even when severe walking wear wear 5 `` proceeds. However, if the shape of the rim is too narrow, as shown in the lower portion of FIG. 4A, the rim-shaped protrusion 21 may be damaged (b) by impact from the ground when walking. Of course, if you want to sacrifice the fit can provide the rim-shaped protrusion 21 as a strong member.

Thus, as shown in FIG. 4B, a protrusion 21 having a shape that forms a gentle inclination from the outer edge 20e1 toward the inner edge 20e2 may be formed, and in this case, resistance to the impact and friction may occur. . However, if the slope is too gentle, the effect of reducing the shift is reduced. That is, the width of the original support point e and the shifted support point e `` at the bottom of FIG. 4B is increased.

As shown in Fig. 2B, first, a large inclination is given from the outer edge 20e1 and proceeds to the center portion 20m at a portion, and then no inclination is given; Such that the inclination naturally decreases as the curvature r is given, as in the example of FIG. 4C; A compromise form is also possible.

Returning to the example of FIG. 4B again, the inclination is extended to the inner edge 20e2 so that the diameter of the outer edge 20e1 is larger than the diameter of the inner edge 20e2 (do> di). Even if the camber angle is reduced, the inner edge 20e2 is not grounded when walking.

Furthermore, if the inclination is sufficient, the positive camber pc may be omitted at all. That is, as shown in FIG. 5A, the bearing 20a of the roller 20 may be kept horizontal (h) while a positive camber may be obtained. In this case, as shown in FIG. 6F, the depression 22 may be deepened, and conversely, the role of the protrusion 21 may be strengthened.

However, in the above-described configuration method, the circumference of each other is different due to the difference between the diameter do of the outer edge 20e1 and the diameter di of the inner edge 20e2, so that the outer and inner edges 20e1 and 20e2 have one time. There is a difference in the distance between the halls and the clouds are not smooth. In contrast, as shown in FIG. 5B, the rollers 20 may be bisected so that each rotates independently. At this time, the whole is regarded as one roller 20.

6A to 6E illustrate a case in which the protrusion 21 is formed at the inner edge 20e2 of the roller 20, in which case the outer edge 20e1 can be matched with the size of the circumference. Cloud rotation is smooth.

In addition, when the outer and inner sides of the roller 20 are used by switching, the outer edge 20e1 and the inner edge 20e2 share the walking single wear 5 ′ as shown in the example of FIG. 6D. 5 ') can be prevented from proceeding and thus the durability of the roller 20 can be further extended.

On the other hand, as shown in Figure 7, the roller 20 can reinforce the grip force, especially when the ground state is soft like mud or contains foreign matter such as sand, the user 1 left foot when skating (2) or pushing the ground (5) sideways with the right foot (3) to push (f1) the projection (21) to dig into the ground (5) to provide a bearing force (f2) against the pushing (f1) Because. On the severely slippery surface, as illustrated in FIG. 6E, an additional protrusion 21 ′ may be formed on the center side 20m outside the outer edge 20e1 or the inner edge 20e2. In this case, it can be mounted to be detachable, such as a separate rim (21r) illustrated in Figure 6C. And even when passing through the puddle can be drained well to the depression 22 to maintain the ground and effective ground.

In the present invention, a single shoe 4 may be used by mixing the rollers 20 illustrated in various forms. Some may be mounted by giving a positive camber pc as in FIG. 3 and some may be mounted without giving as in FIG. 5. In the example of FIG. 1, the front wheel is equipped with a roller 20 having a diameter of the outer edge 20e1 larger than the diameter of the center side 20m (in this case, the positive camber angle can be reduced), and the rear wheel Is equipped with a roller 20 having the same diameter of the outer edge 20e1 and the diameter of the center side 20m (at this time, the positive camber (pc) camber angle cannot be reduced).

In the roller 20 of the present invention, when skating, even when the center side 20m is not actually grounded due to the protruding portion 21, the virtual center side is grounded between the inner and inner edges 20e1 and 20e2. Since 20m is formed to maintain surface contact with the ground, the effect of facilitating the center holding using a wide roller remains unchanged.

The above is summarized with reference to the example of FIG.

8A and 8B is a case where the diameter of the outer edge 20e1 of the roller 20 and the diameter of the center side 20m are the same. At this time, the support point e` shifted away from the original support point e due to the walking wear wear 5 '. In other words, the width w ′ between the outer edge 20e1 and the inner edge 20e2 of the roller 20 becomes narrower than the original width w. 8B, the roller 20 is divided into two parts, or a plurality of the rollers are combined to support the bearing 20a in one axis, and the whole is viewed as one roller 20.

As shown in FIG. 8C, when the diameter of the outer edge 20e1 of the roller 20 and the diameter of the center side 20m are different, the rollers 20 having a supporting point to be grounded at a very small point exist in parallel. Combined to form a wide roller 20. Since the support point is provided as a very small point, the width w of the roller 20 remains unchanged no matter how the walking wear wear 5 ′ proceeds at the outer edge 20e1.

In addition, since the walking single wear 5 'is advanced only to the outer edges 20e1, when it is a problem in the balance of the rollers, by walking by switching the outer and inner sides of the rollers as shown in FIG. 8D. Only one side can prevent the walking gait (5``) from progressing severely.

Meanwhile, FIG. 9 illustrates that at least one of the rollers 20, 20 ′ is formed to have an extension p extending further outward from an outer edge or an outer surface thereof. Since the impact can be dissipated from, the outer edge of the roller or the protrusion can be prevented.

The extension portion p is preferably such that the ground width of the roller is defined so as to ensure a sufficient support width and then extended. However, if the extension portion is excessively expanded, the roller may lead to a narrowing of the width that substantially grounds the entire width occupied by the bottom of the shoe.

More specifically, the extension may be formed in the original body and the roller, and may be formed by coupling a separate extension (p) to the outer surface / outer edge of the roller as shown in Figure 9A.

In the roller with positive camber as shown in Figs. 9 A to D, Fig. 9B extends the outside of the roller in the form of Fig. 4C or Fig. 6F; 9C extends the outside of the roller of the form of FIG. 3 or 4 A; FIG. 9D illustrates an example of extending the outer side of the roller of FIG. 8C. The extension part may spread the ground and the ground area with a taper angle at least as the diameter thereof progresses to disperse the impact and friction.

In the case of a roller configured without a positive camber as shown in the example of FIG. 5, an extension portion extending in parallel from the outside of the roller of FIG. 4A or FIG. 5 may be formed as shown in FIG. 9 (E, F). .

On the other hand, as shown in Fig. 9G, in the roller 20` which does not constitute the protrusion 21, an extension portion is formed to contact the ground by giving the taper angle, thereby widening the support surface of the outer edge to reduce wear. to be. In the above, it can also be said that the said extension part plays the role of the outer side (edge) of a roller.

In summary,

A friction part disposed along the outer side of the bottom of the shoe; In the skating shoe (or skate structure attached to the shoe) comprising; and rollers disposed along the inner side of the bottom of the shoe,

At least one of the rollers has a side (at least one of an outer side, an inner side, or a middle side) having a different size of its outer circumference. For example, the roller may have a diameter (outside) of the outer side (edge) different from the diameter of the middle side or the inside (large or small); The diameter of the intermediate side is different from the diameter of the inner side.

According to another embodiment shown in Figure 10 to 12,

A plurality of rollers are provided, and the height (height) of the bearing 20a of each roller serving as the outer edge 20e1 and the inner edge 20e2 is differently provided (h1 <h2 or h1> h2).

The structure of the bracket or frame fr for bearing the roller 20 may be such that the rollers receive the rollers 20a by placing a frame between the plurality of rollers as shown in FIG. 10C; Conversely above and around both rollers as shown in FIG. 10A and bearings from outside the rollers; Using the above two methods can bear bearings on both the outer rollers between the lower rollers, as shown in Figure 10B, in this case can take the most robust bearing structure.

The placement and configuration of the rollers as viewed from the bottom of the shoe may be all bearing in one boxed frame as in the example of FIG. 11A or 11B; As illustrated in FIG. 11C, individual frames may be separately configured and each of the plurality of rollers may be supported by bearing.

Through the illustrated configuration as described above, it is possible to give the difference between the height and height while taking the normal roller diameter equally, so that it is easy to supply and manage the rollers and to maintain the rolling friction due to the diameter difference uniformly. Also, the rollers can be mounted directly upright without being tilted.

Of course, even in the case of the above example, if necessary, it is possible to mix the rollers of different diameters or tilt the rollers.
