Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a skate blade assembly having a plurality of blades arranged side by side,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skate used on ice and a blade assembly therefor, and more particularly, to a skate boots having a blade assembly on the lower surface thereof, the blade assembly having a plurality of blades And the imaginary line connecting the lowermost ends of the plurality of blades in the transverse direction is disposed so as to be curved downwardly convex at the center while going in the width direction (lateral direction) of the boots, so that even when the wearer's ankle is inclined, To a blade assembly and a skate having the blade assembly.

The skates used on the ice generally have a structure in which one blade perpendicular to the lower side is coupled. Korean Patent No. 10-1105314 discloses an example of a skate according to the prior art.

However, in the case of a conventional skate having only one vertical blade, it is very difficult for a wearer to center the skate, so that a young or newbie wears a skate and becomes very difficult even when standing on ice. In particular, even if you simply stand on ice without sliding over ice, the muscles around your ankle, including the muscles around your body, must be strained to balance, and the wearer will feel fatigued easily. Particularly, in a conventional skate, when the wearer's foot is inclined, the center of gravity of the inclined foot is shifted from the position where the blade is present. That is, there is no blade at the vertically downward position from the center of gravity of the tilted foot. Therefore, when the wearer's foot tilts, the wearer may lose balance or damage to the ankle. In order to maintain the balance of the body, the muscles around the ankle, as well as the muscles around the body, .

Also, in this conventional skate, since one vertical blade has a considerable vertical height, the position of the boots is located at a high place on the ice, so that even if the boots are slightly inclined, a large rotational force is applied to the wearer's ankle It is very likely that the ankle will be overloaded or injured, and the risk of injuring the other person by the blade is very high.

See Korean Patent Registration No. 10-1105314 (2012. 01. 18. Announcement).

The present invention has been developed in order to solve the problems of the conventional skate as described above. Specifically, it is possible to allow a beginner to easily learn a skate, and to allow a wearer to easily balance the skate even when the wearer's foot is inclined The present invention aims to provide a skate capable of reducing fatigue when worn as well as improving the feeling of stability and a blade assembly provided in such a skate.

In the blade assembly of the present invention, a plurality of blades are provided on the bottom surface of the bottom plate in a state where the bottom plate itself is manufactured in a shape having a transverse section whose center is curved downwardly convexly, The imaginary line connecting the blade edges to each other in the lateral direction may be curved downward from the center, or alternatively, the bottom plate may be made of a flat member; Each of the plurality of blades integrally attached to the lower surface of the bottom plate has a protruding height at the center thereof being the largest and a protruding height being gradually smaller toward the lateral edge, The imaginary lines connected to each other in the transverse direction may be formed into a curve shape in which the center line is convex downward.

Further, in the blade assembly of the present invention, the blade may be formed in a downward convex curve shape in which the blade edge is located in the front and rear portions in the shape of the longitudinal direction, and further, in the plurality of blades, The blades located on both sides may have a configuration in which the blade edge is formed by inclining the lowermost end of the blade so that the inner surface of the blade has a protruding height shorter than the outer surface thereof.

Further, in the present invention as described above, the bottom plate forms the bottom of the boot for skating; The plurality of blades may be coupled to the bottom plate in such a manner that an upper end of the plurality of blades is stuck to the bottom plate. The blade, which is laterally inward or outward relative to the center- Shape.

Further, in order to achieve the above object, the present invention provides a skate having the above-described blade assembly provided on the lower surface of the boot.

The blade assembly and the skate having the blade assembly according to the present invention are provided with a plurality of blades. Since the plurality of blades have a curved edge line connecting lateral edges, even if the wearer's foot tilts, the blade edge touches the ice surface So that the wearer of the skate according to the present invention is able to easily balance while feeling a greater sense of stability, and thus the muscles of the body are excessively So that the wearer feels less fatigue, and the risk of ankle injury is lowered.

Further, since the skate according to the present invention can naturally tilt the ankle and move it agile, the activity is greatly improved, so that the wearer has the advantage of being able to slide easily and quickly even in a curved section.

On the other hand, the higher the blade, the higher the risk that another person will be injured by the blade. The skate according to the present invention has a high stability, so that the height of the blade may be low, Effect is exerted.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby. For reference, the width direction of the wearer's foot is referred to as "lateral direction " and the longitudinal direction of the foot is referred to as" longitudinal direction " throughout the specification including claims and summary. The expression "transverse section" means a section cut in the transverse direction and viewed in the longitudinal direction, and the expression "longitudinal section" means that the cross section cut in the longitudinal direction is a cross- it means.

1 and 2 show a schematic perspective view showing a skate 100 according to a first embodiment of the present invention, respectively, in different directions, and FIGS. 3 and 4 show a first perspective view of the skate 100 according to the first embodiment of the present invention, There is shown a perspective view schematically showing the blade assembly 10 coupled to the lower portion of the boots 20 separately in the embodiment, but showing a different view direction. 5 is a schematic cross-sectional view taken along line A-A of FIG. 3, that is, a cross-sectional view of the blade assembly 10 in a transverse direction.

A skate 100 according to the present invention includes a boot 20 directly surrounding the wearer's foot and a blade assembly 10 coupled to a lower surface of the boot 20. [ The blade assembly 10 includes a bottom plate 11 and a plurality of blades 12 vertically provided on the bottom surface of the bottom plate 11. [ In the present invention, the blades 12 are elongated in the longitudinal direction, and a plurality of the blades 12 are arranged side by side with a space therebetween. The blade 12 has a height at which the lowermost end of the blade 12 protrudes, The height is the highest in the center, and has a shape that decreases as it goes to both side edges of the lateral direction. That is, imaginary lines (indicated by dotted lines KK in Fig. 5, hereinafter referred to as "edge transverse virtual lines") in which blade edges (the lowermost portions of the blades) are connected to each other in the transverse direction with respect to the plurality of blades 12 ) Is curved downward from the center.

In the case of the first embodiment shown in Figs. 1 to 5, the bottom plate 11 itself is manufactured in a shape having a transverse section whose center is curved downwardly convexly, and a plurality of A blade 12 is provided. In the case where the lower surface of the bottom plate 11 is configured to be bent as described above, when the bent curves, that is, the downwardly convex curves in the cross section, exactly match the desired curvature, By making the same, it is possible to make the edge transverse connected imaginary line convex downward with a desired curvature. However, by adjusting the height of each of the plurality of blades 12 irrespective of the bent curvature of the lower surface of the bottom plate 11, the edge transverse connection virtual line may have a desired curvature. Furthermore, by making the bottom plate 11 a flat plate member and adjusting the height of the blade 12, the edge transverse connecting imaginary line can have a desired curvature. Such an embodiment will be described later.

Meanwhile, in manufacturing the blade assembly 10 according to the present invention by connecting a plurality of blades 12 to the bottom plate 11 so that the edge transverse connection line is curved downwardly convexly, In the case of the blade 12 positioned on both lateral sides from the center of the imaginary line, it is preferable to form the blade edge by oblique processing. Since the blade 12 is made of a plate member, it has a certain thickness. On the other hand, the region where the blade 12 contacts the ice surface is preferably a line. Therefore, in the case of the blades 12 located on both sides in the lateral direction from the center as shown in Fig. 5, the inner surface of the blade 12 is made shorter in height than the outer surface, It is preferable that the lowermost end of the blade edge be inclined to form the blade edge.

On the other hand, in the present invention, it is also preferable that the blade edge is made of a gentle downward convex curve so that the front portion and the rear portion are included in the shape in the longitudinal direction. 6 is a schematic cross-sectional view taken along the line B-B of FIG. 3, that is, a schematic longitudinal cross-sectional view at the center of the blade assembly 10. As shown in FIG. 6, it is preferable that the blade edge has a downwardly convex curve which is gentle as a whole because the blade edge has a longer length in a downward direction than a starting portion and an end portion in the longitudinal direction.

In the present invention, the curved bottom plate 11 may be used to form a curved line in which the edge transverse connection lines are convex downward from the center with respect to the plurality of blades 12. However, as mentioned above, Instead of using the plate 11, the height of the blade 12 itself may be adjusted. FIG. 7 shows a schematic perspective view of a blade assembly 10 provided in a second embodiment of the present invention, and FIG. 8 shows a schematic cross-sectional view taken along line C-C of FIG. 7 and 8, the bottom plate 11 is made of a flat member and a plurality of blades 12 are attached integrally to the lower surface of the bottom plate 11, By placing the blade 12 having the highest height at the center of the blade 12 and having a height gradually lowering toward the lateral edge, the edge transverse virtual line is convex downward from the center with respect to the plurality of blades 12 To form a curved shape.

The blade assembly 10 is joined to the lower surface of the boot 20 to form a skate. In the first and second embodiments described above, the blade assembly 10 is attached to the boots 20 And an engaging member (30) provided for attaching to a lower surface of the bottom plate (11). The upper flat plate of the engaging member 30 is engaged with the bottom of the boot 20 so that the upper flat plate of the engaging member 30 is engaged with the lower flat plate of the boot 20, And the like. However, the configuration and shape of the coupling member for coupling the blade assembly 10 to the boot 20 are not limited to the embodiments shown in Figs. 1 to 8 above.

9 and 10 are schematic perspective views showing the blade assembly 10 according to the third embodiment of the present invention, respectively, and FIG. 11 is a schematic perspective view taken along the line DD of FIG. 10 A cross sectional view is shown in FIG. 11. In FIG. 11, only the blade assembly 10 is shown in cross-section for convenience, and the boot 20 is not shown in cross-sectional form.

9 to 11, in attaching the blade assembly 10 to the boot 20, a coupling member 40 having a thickness of synthetic resin or the like is provided on the upper surface of the bottom plate 11 . That is, an engaging plate 40, which is made of synthetic resin or other various materials and has a flat upper surface, is integrally attached to the upper portion of the bottom plate 11, and the flat plate- The upper surface may be integrally attached to the bottom of the boots 20 by fastening means such as bolts or an adhesive. That is, the coupling plate 40 corresponds to the coupling member 30 described above.

Although not shown in the drawings, even in the case of the blade assembly 10 having the bottom plate 11 made of a flat member as shown in Figs. 7 and 8, And can be coupled to the boot 20 using a coupling plate 40. The coupling of the blade assembly 10 to the boot 20 in the same manner as described above is merely exemplary and in a skate with one blade, It can be used for the combination of the assembly 10 and the boot 20.

Although the bottom plate 11 of the blade assembly 10 is described as being a separate member from the bottom surface of the boots 20 in the above embodiment, the bottom plate 11 of the blade assembly 10 11 may form the bottom of the boot 20. Fig. 12 shows a schematic cross-sectional view corresponding to Fig. 11 showing another embodiment of the present invention in which the bottom plate 11 of the blade assembly 10 corresponds to the bottom of the boot 20. Fig. Unlike FIG. 11, the boots 20 are also shown in cross section in FIG. In Fig. 12, a line K-K represents a hypothetical line connecting the blade edges (the lowermost portion of the blade) in the transverse direction, that is, an "edge transverse connecting imaginary line ".

12, the bottom plate 11 of the blade assembly 10 constitutes the bottom of the boots 20, and the plurality of blades 12 are engaged with the bottom plate 11 . 12, since the depths at which the blades 12 of the same vertical height are embedded in the bottom plate 11 are different from each other, the curved line in which the edge transverse connection lines for the plurality of blades 12 are convex downward from the center The blade 12 may be constructed so as to have the same depth at which the blades 12 are embedded in the bottom plate 11 but have a curved edge-to-edge connection imaginary line in which the vertical heights of the plurality of blades 12 are different It is possible.

FIG. 13 is a schematic lateral cross-sectional view showing the state when the skate is inclined according to the embodiment shown in FIG. 1, and FIG. 14 is a view showing a state when the skate is inclined according to the embodiment shown in FIG. Is shown in a schematic cross-sectional view. 13, only the blade assembly 10 is shown in a cross-sectional view, and the boot 20 is not shown in a cross-sectional view. 14, both the boots 20 and the blade assembly 10 are shown in cross-sectional form.

In the skate according to the present invention, when the boots 20 are tilted, the blade assembly 10 is also tilted so that the boots 20 are supported before the boots 20 are tilted, as shown in Figs. 13 and 14 Another blade 12 different from the blade 12 touches the ice surface, so that the bottom of the boot 20 in an inclined state continues to be supported vertically. That is, since the skates according to the present invention are provided with the plurality of blades 12 and the imaginary lines connecting the edges of the blades 12 are curved, even if the boots 20 are inclined, 20, there is always a blade touching the ice surface 300 below the vertical of the boot floor. Therefore, the skate wearer can easily balance while feeling a sense of security, and accordingly the muscles of the body are prevented from being excessively tensed so as to balance, thereby reducing the fatigue felt by the wearer and reducing the risk of ankle injury .

Also, since the skate according to the present invention greatly improves the activity, the skate has an advantage that it can be easily and quickly slid even in a curved section.

The higher the blade, the higher the risk of injury to others due to the blade. The skate according to the present invention has a high stability, so that the height of the blade may be low, and thus an additional effect of lowering the risk of injury of the other person due to the blade .

On the other hand, in the present invention, the blades on both sides of the plurality of blades, except for the blade located at the center, may have a curved shape curved in the transverse direction. Fig. 15 is a schematic perspective view of a skate having a blade assembly according to the embodiment shown in Fig. 12, in which the blade is curved in a laterally curved shape, and Fig. 16 is a schematic view of the blade assembly shown in Fig. A schematic bottom view is shown.

In the present invention, all of the plurality of blades 12 constituting the blade assembly 10 may be extended in a straight line in the longitudinal direction as in the embodiment shown in Figs. 1 to 14, but in Figs. 15 and 16 As shown, a portion of the blade 12 may have a curved shape that is laterally curved. In this case, it is very advantageous when running the curve.

The phenomenon in which the boot is inclined also occurs when the skate is applied to the curve main body. As described above, in the present invention, when the boot 20 is tilted, another blade 12, which is different from the blade 12 that supported the boot 20 before the boot 20 is tilted, If the blade that touches the ice surface 300 when the boot 20 is tilted is curved in the same direction as the curved direction of the curved line, the blade is curved in a direction of the ice surface 300 So that the wearer can easily travel on the curved main body.
