Description

Slidable and non-slidable shoes

Technical Field

The present invention relates to a slidable and non-slidable shoe, and more particularly, to a slidable and non-slidable shoe that can slide and prevent slipping on ice or snow, and that can minimize the number of spikes and stably perform various games, movements, sports, fitness, and the like on ice or snow by securing a frictional force at an optimal position on a sole surface by arranging a plurality of spikes along proximal phalanges and metatarsals.

Background

Conventionally, many people enjoy games or sports using properties such as skates, snowboards, skis, and the like on ice or snow, and recently, a ski resort, a skating rink, a ski rink, and the like are artificially constructed, and such games or sports have become entertainment cultures of many people.

However, in order to play such a game, expensive skates are required for skating, and expensive equipment is also required for skiing, snowboarding, skiing, and the like, and therefore, there is a problem that the proximity of the game is low.

In addition, since the skates can be used only on ice, and the snowboard, the ski, and the like can be used only on snow, there is a problem that usable places are limited compared to expensive equipment.

Further, since a game on ice or snow mainly uses equipment such as skates, snowboards, single-board snowboards, and skis using sliding characteristics, there are difficulties in that: that is, in order to brake, it is necessary to perform an operation using various equipment (a blade is necessary in the case of skates, and a hill slide (hill slide) is necessary in the case of snowboarding), or to perform additional equipment and operation (a ski pole and a blade are necessary in the case of skiing).

Namely, the following difficulties are encountered: even with expensive equipment, it is necessary to be skilled in mastering the extra motion for braking in order to be skilled in playing the corresponding game or related sports activities.

Further, since equipment such as conventional skates, snowboards, single-board snowboards, and the like is very expensive, and the access threshold of ordinary people is high, and the popularization thereof is limited, there is a problem that good excavation cannot be obtained by a new sport item on a slidable ice surface or snow.

Detailed Description

The detailed description and drawings include specific details of embodiments.

The advantages and features of the present invention, and the methods for attaining them, will become apparent from the following detailed description of the embodiments and the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be implemented in various forms. The present embodiments have been disclosed only for a complete disclosure of the present invention and are provided for informing those skilled in the art of the scope of the present invention as a complete description of the present invention, which should be defined by the scope of the appended claims. Like reference numerals refer to like elements throughout the specification.

The invention will now be described by way of example with reference to the accompanying drawings which illustrate slidable and non-slidable shoes.

A slidable and non-slidable shoe according to an embodiment of the present invention may be configured to include outsole 110, stud 120, and slider 130.

Outsole 110 is an outsole disposed on the bottom surface of the shoe, and may be made of at least one material selected from among PVC, EVA, natural Rubber, synthetic Rubber, polyurethane, carbon Rubber (carbon Rubber), solid Rubber (solid Rubber), and raw Rubber (Gum Rubber), but is not limited thereto.

In fig. 1, although the outsole 110 is formed in a form separated by a heel portion 110a and a forefoot portion 110b, the outsole 110 may be formed on the entire sole surface according to the shape of the shoe. A plurality of spikes 120 are formed on the outsole 110 to protrude toward a sliding surface (hereinafter, referred to as a "floor surface") of an iceboard, snow or the like. In the case of wearing the shoe, the studs 120 may perform a non-slip action by rubbing against the floor surface. That is, the user can perform a braking action by pressing the sole surface on which the spikes 120 are formed, against the floor surface during sliding.

The spikes 120 are preferably constructed of stainless steel (stainless steel) which has sufficient durability on ice or snow and is not susceptible to corrosion.

As shown in fig. 2 and 3, the spikes 120 are divided into a first spike 120a disposed in the proximal phalanx B1 region of the sole and a second spike 120B disposed in the metatarsal B2 region of the sole.

The first shoe nail 120a may perform various amusement, motions, exercises or fitness on ice or snow by securing a frictional force on the floor surface of a proximal phalanx (B1) portion, and the second shoe nail 120B may secure a frictional force by securing a starting position of a metatarsal (B2) portion, i.e., a plantar arch (foot arch), such that a user does not easily slip on the floor surface and can stably maintain the body center of gravity.

The first shoe nail 120a is disposed in the middle of the proximal phalanx B1 corresponding to the first, third, and fifth toes, respectively, and the second shoe nail 120B is disposed in the middle of the metatarsal bone B2 corresponding to the second and fourth toes, respectively.

Generally, in order to move as shown in fig. 4, the proximal phalanx B1 portion of the heel section 110a is in contact with the floor surface and the metatarsal B2 portion is in a state of being away from the floor surface in a state where the heel section 110B is lifted, and in order to stop as shown in fig. 3, both the proximal phalanx B1 and the metatarsal B2 portion of the heel section 110a are in a state of being in contact with the floor surface.

In this case, by setting the number of the first spikes 120a arranged in the proximal phalanx B1 portion to be greater than the number of the second spikes 120B arranged in the metatarsal bone B2 portion, even in a moving operation requiring a high frictional force in a narrow area, the sliding phenomenon of the contact surface can be effectively prevented by the frictional force of the first spikes 120 a.

Furthermore, since the weight of the user can be effectively supported in a distributed manner by disposing the plurality of spikes 120 in the proximal phalanx B1 and metatarsal bone B2 portions, the body center of gravity can be maintained while the slippage on the floor surface is not likely to occur, and the non-slip operation can be smoothly performed while minimizing the total number of spikes 120.

In the present embodiment, as the spikes 120 are not disposed on the distal phalanges (B3) of the sole, i.e., the toe portions, the toe bending motion can be smoothly performed in a state where the shoe is worn.

As shown in the enlarged view of fig. 1, the stud 120 is conical in shape, formed with a radius gradually decreasing in the protruding direction, and preferably does not have a tip formed sharply like an awl but is formed to have a prescribed flat or curved surface. This is because when the tip of the spike 120 is formed sharply like an awl, the spike 120 may cause damage to the floor surface and the wearing feeling of the user may be reduced. Furthermore, by the shape of the shoe spike 120, surrounding persons or users can be prevented from being injured by the sharp tip of the shoe spike 120. However, if the tip surface is a flat surface, if the cross-sectional area is too large, the shoe spike 120 cannot be sufficiently inserted into ice, and the braking force and the feeling of stability may be reduced, and therefore, it is preferable that the diameter of the tip surface be set to 0.5mm or more and 2.0mm or less, and the diameter may be changed depending on the number, position, shape, or the like of the shoe spike 120.

Meanwhile, when the protruding length is long, it is difficult to perform various motions such as light jumping or continuous stepping because the stud 120 is inserted too deeply into the floor surface; when the protrusion length is too short, the user may lose the center of gravity and fall down because the user cannot sufficiently provide friction because of insufficient insertion into the floor surface. Therefore, the stud 120 is preferably set to a protruding length of about 2.5 to 5mm so as not to be inserted too deeply into the floor surface while providing an appropriate frictional force during various motions. However, the protruding length of such studs 120 may be adjusted as appropriate depending on the number, location, shape or floor surface characteristics of the studs 120.

In addition, the studs 120 may be configured to be replaceable.

As shown in fig. 5 and 6, the lower fixing portion 125 is fixed to the outsole 110, and a screw is formed on an inner surface of the central hole 126. As shown in the drawings, the outsole 110 may be formed in multiple layers according to the shape of the lower fixing portion 125, so that the lower fixing portion 125 is easily fixed on the outsole 110. Alternatively, the outsole 110 may be formed in a single layer, and an insertion hole having a step is formed according to the shape of the lower fixing portion 125 so that the lower fixing portion 125 can be inserted.

Meanwhile, it is preferable that the outer peripheral edge shape of the lower fixing portion 125 is constructed in a concavo-convex structure so that the lower fixing portion 125 can be firmly fixed in the outsole 110.

The upper spike 121 is replaceably fixed to the lower fixing portion 125. A protruding portion 122 is formed at the lower end of the upper spike 121, and a thread is formed on the outer circumferential surface of the protruding portion 122. Therefore, the projection 122 can be inserted into the hole 126 of the lower fixing portion 125, and the upper spike portion 121 can be screwed to the lower fixing portion 125 through the screw thread of the inner side surface of the hole 126 and the screw thread of the outer side surface of the projection 122.

A spike 120 is formed to protrude from the upper surface of the upper spike part 121. Accordingly, since the upper spike part 121 may be detachably coupled to the lower fixing part 125 in the present invention, when the spike 120 is damaged or worn, it is possible to easily replace the spike 120 with a new one.

As shown in fig. 7 to 9, the sliding cover 130 is detachably coupled to the bottom surface of the outsole 110 so as to cover at least a portion of the shoe studs 120, and the bottom surface facing the floor surface is formed of a smooth sliding member, thereby forming a sliding area.

Thus, the user can perform the sliding motion by using the heel portion 110a where the sliding cover 130 is located.

The sliding member formed on the bottom surface of the sliding cover 130 is preferably formed of one of teflon, PA11 (nylon), thermoplastic Elastomer TPE (Thermoplastic Elastomer), thermoplastic Polyurethane TPU (Thermoplastic Polyurethane), and acetal, which is easily slid on the floor surface, but is not necessarily limited thereto. An additional sliding member, teflon, may be formed on the bottom surface of the slide cover 130, but the entire slide cover 130 may also be formed of teflon.

Grooves 132 corresponding to the shape and arrangement of the spikes 120 may be formed on the upper surface of the sliding cover 130 so as to insert the spikes 120 protruding from the bottom surface of the outsole 110. The sliding cover 130 may be coupled to be removable from the outsole 110 by interference fitting the studs 120 in the slots 132.

Alternatively, the sliding cover 130 may be detachably coupled under the outsole 110 by a magnetic force.

For example, a groove 132 for inserting the stud 120 may be formed on the upper surface of the slide cover 130, and the inner sidewall of the groove 132 may be formed of a magnet or a metal. In addition, the studs 120 inserted into the slots 132 may be formed from magnets or metal. Accordingly, the sliding cover 130 may be detachably coupled under the outsole 110 by the force of the magnetic force generated between the inner sidewalls of the groove 132 and the spikes 120.

At this time, in order to intensify the magnetic force, a coupling by the magnetic force may be configured between the upper surface of the slide cover 130 and the outsole 110.

Further, in this embodiment, the sliding cover 130 may be detachably coupled to the heel portion 110a configured with the first and

second spikes

120a and 120b, and the non-sliding region may be changed to the sliding region.

In addition, although the slide cover 130 is detachably coupled to the lower surface of the outsole 110 by magnetic force in the present embodiment, the slide cover 130 may be detachably coupled by various coupling structures other than the coupling structure using the magnet.

The sliding cover 130 shown in fig. 7 and 8 may be formed to cover the entire forefoot portion 110a of the bottom surface of the outsole 110. Thus, the user can perform a sliding motion by the forefoot portion 110a in combination with the slide cover 130.

When a sliding cover 130 is incorporated on the stud 120, it is preferred that the height step between the bottom surface of the sliding cover 130 and the end of the stud 120 exposed from the outsole 110 is not excessive. This is because when the step difference is excessively large due to an excessively large thickness of the slide cover 130, it is difficult to control the motion due to an excessively large range of motion of the sole for the sliding motion and for the non-sliding motion, and it may be inconvenient in moving by the step.

Further, when the thickness of the slide cover 130 is set to be thicker than necessary, a user may feel that the slide cover floats on the floor surface, and thus the thickness of the slide cover 130 is preferably set to be as thin as possible within a range that can cover the stud 120. In this embodiment, the thickness of the slide cover 130 may be set to about 5 to 6 mm. When such a slide cover 130 is fixed only to the heel portion 110a of the outsole 110, as the support height of the heel portion 110a of the shoe user rises by the thickness of the slide cover 130, the body weight of the user moves toward the heel portion 110b, and thus there is a problem in that it is difficult to smoothly perform the sliding motion using the slide cover 130 disposed at the heel portion 110a.

Therefore, in the present embodiment, as shown in fig. 9, the body weight and mind can be prevented from moving toward the heel portion 110b when the slide cover 130 performs the sliding motion by setting the thickness of the heel portion 110b of the outsole 110 to be about 5 to 6mm thicker than the heel portion 110a.

In addition, in the present embodiment, when the thickness of the forefoot portion 110a of the outsole 110 is excessively thick, the user feels floating on the floor surface, and thus it is difficult to perform a stable motion while maintaining the center of gravity of the body. On the contrary, when the thickness of the outsole 110 is too thin, the protruding feeling of the studs 120 is directly transmitted to the user's foot, and thus it is difficult to perform a continuous motion, although there may be a feeling that the sole surface is stably attached to the floor surface. Therefore, in the present embodiment, the thickness of the outsole 110 is set to about 5mm, which is a thickness capable of providing a proper contact feeling with the floor surface and properly alleviating the protruding feeling of the studs 120, but the thickness is not limited thereto and may be appropriately adjusted according to the physical properties of the outsole 110.

Fig. 10 is a perspective view of a slide cover according to another embodiment of the present invention, fig. 11 to 14 are views showing a shape of the slide cover of fig. 10 coupled to a sole surface, and fig. 15 is a view showing a state where the slide cover is coupled to one of both shoes.

Fig. 10 shows a slide cover 130 having various shapes. The sliding cover 130 shown in fig. 10 (a) is formed with three grooves 132 so that all of the first spikes 120a can be inserted, the sliding cover 130 shown in fig. 10 (b) is formed with two grooves 132 so that all of the second spikes 120b can be inserted, and the sliding cover 130 shown in fig. 10 (c) is formed with three grooves 132 so that the first spikes 120a corresponding to the positions of the first and third proximal phalanges and the second spikes 120b corresponding to the positions of the second metatarsus can be inserted.

That is, the user can slide the entire region of the heel section 110a by coupling the slide cover 130 to the first shoe stud 120a and the second shoe stud 120b as shown in fig. 11.

Meanwhile, when the slide cover 130 is coupled to the first shoe nail 120a portion as shown in fig. 12, the proximal phalanx (B1, refer to fig. 2) region is set as the slidable region, and the metatarsal (B2, refer to fig. 2) region is set as the non-slidable region.

In contrast, when the slide cover 130 is coupled to the second stud 120B as shown in fig. 13, the metatarsal (B2, see fig. 2) region is set as the slidable region, and the proximal phalanx (B1, see fig. 2) region is set as the non-slidable region.

In addition, when the slide cover 130 is coupled to the positions corresponding to the first and third proximal phalanges and the second metatarsal bone as shown in fig. 14, a sesamoid bone (sesamoid bone) region of the hallux toe may be set as a slidable region.

Thus, the user can perform a sliding motion using the sole area where the slider 130 is located, and can perform a non-sliding (scram) motion using the sole area where the studs 120 are exposed.

In this embodiment, the non-sliding action of heel portion 110a is achieved by providing first cleat 120a and second cleat 120b on the bottom surface of heel portion 110a of the shoe, where the sliding action of heel portion 110a is achieved by incorporating sliding cover 130. That is, the sliding area and the non-sliding area are changed according to whether the slide cover 130 is coupled or not.

Further, as shown in FIG. 15, the first stud 120a and the second stud 120b of the heel portion 110a are exposed by incorporating the slide cover 130 in the heel portion 110b of the right shoe (the shoe on the left in the figure), and the studs 120 are hidden by incorporating the slide cover 130 in the heel portion 110a and the heel portion 110b of the left shoe (the shoe on the right in the figure). Thus, the user can use the right forefoot heel portion 110a to achieve the non-sliding motion, and can use the right heel portion 110b, the left forefoot heel portion 110a, and the heel portion 110b to achieve the sliding motion.

In addition, the ankle should be freely moved for smooth sliding motion and non-sliding motion. When the ankle is completely covered due to the high height of the upper (uppers), the left and right movement of the ankle is not free as in the lateral bow step, and on the contrary, when the height of the upper (uppers) is low as in the handy shoes, the shoes are liable to fall off or fail to sufficiently hold the ankle, increasing the risk of ankle injury.

Therefore, the upper (uppers) is preferably constructed such that the height thereof reaches just below the ankle as in the case of the short-cut and the roller skates, so that the movement of the ankle in the left-right direction can be smooth, and the ankle can be tightened with the string in order to hold the ankle to the maximum.

Meanwhile, it is preferable that the inner space of the front end (vamp) covering the toes and the instep is made wide so that the toes can be exercised, thereby securing free movement of the toe portion such as yoga and pilates.

The scope of protection of the invention is not limited to the embodiments described above, but can be implemented in many forms of embodiments within the scope of the appended claims. Various modifications to the present invention can be made by those skilled in the art without departing from the spirit of the present invention claimed in the claims.
