International Publication No. 07/094649 Pamphlet

  In the roller skate described in Patent Document 1, as described above, the frictional contact member is formed so as to protrude downward from the base material portion along the length direction of the shoe at the position of the outer portion of the shoe sole. Yes. Thus, the friction contact member functions to prevent the shoe sole from bending along its length.

However, when the shoe wearer walks, he / she moves forward by kicking up the “heel” from the walking surface.
Therefore, the roller skate described in Patent Document 1 can easily switch between the walking mode and the skating mode simply by tilting or returning the base material portion, and comfortable running is possible in the skating mode. However, there is room for improvement in terms of ease of walking in the walking mode.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve such a problem and to obtain a roller skate that can switch between a walking mode and a skating mode, and that can walk comfortably in the walking mode. To do.

In order to achieve this object, the roller skate of the present invention is
A base material provided in a part corresponding to the shoe sole;
A friction contact member formed so as to protrude downward from the base portion along the length direction of the shoe at an outer position on the shoe sole;
A plurality of inclined rollers provided along the length of the shoe at an inner position in the shoe sole;
A space portion formed upward between the friction contact member and the inclined roller;
In the walking mode, the friction contact member and the inner edge of the inclined roller are configured to contact the walking surface,
In the skating mode, it is configured such that the tread surface of the inclined roller comes into contact with the running surface and the frictional contact member does not come into contact with the running surface by the base member being tilted outward.
A boundary portion between a toe portion of the shoe and a portion on the rear side of the toe portion is configured to be more easily elastically deformed than portions other than the boundary portion.

  Therefore, according to the present invention, the boundary between the toe portion of the shoe and the rear portion of the toe portion is configured to be more elastically deformed than the portion other than the boundary portion, so that the wearer can walk. When the “heel portion” is kicked up from the ground, the shoe sole is easily bent in response to the forward movement, and thus comfortable walking in the walking mode can be realized.

FIG. 6 is a bottom view of the roller skate shown in FIG. 5. It is a figure which shows the state at the time of the walk of the roller skate of FIG. 5 and FIG. It is a side view of the roller skate of other embodiment of this invention. FIG. 9 is a side view of the opposite side of the roller skate shown in FIG. 8. FIG. 10 is a bottom view of the roller skate shown in FIG. 9. It is a side view of the roller skate of other embodiment of this invention. It is a side view of the opposite side of the roller skate shown in FIG.

  In the roller skates shown in FIGS. 1 to 4, reference numeral 11 denotes a shoe body, and 12 denotes a base material portion as a shoe sole. The base material portion 12 is formed with a thick wall integrally with the shoe main body 11 by synthetic rubber, for example.

  The roller skate shown in FIGS. 1 to 4 is attached to the right foot, but is illustrated so as to protrude downward from the base material portion 12 at an outer position in the base material portion 12 constituting the shoe sole. Thus, the friction contact member 13 formed integrally with the base material part 12 or separately from the base material part 12 is omitted, but is formed along the length direction of the shoe. At the lower end of the friction contact member 13, a contact surface 15 that is in contact with the walking surface 14 such as the ground is formed. As shown in FIG. 2, in order to form the contact surface 15, the member 10 having a larger coefficient of friction with respect to the walking surface 14 than the base material portion 12 can be attached to the lower end of the friction contact member 13 by pasting or the like. .

  An inclined roller 16 is provided at an inner position in the base material portion 12 constituting the shoe sole. More specifically, the “toe portion 23” and the “heel portion 28” at the inner positions of the thick-walled base material portion 12 are each formed with a concave portion 17 that opens downwardly and is inclined outward. Yes. A bracket 18 made of light metal or hard resin is attached to the recess 17 as a housing. A wide roller 19 is rotatably supported on the bracket 18. That is, the roller 19 is attached to the base member 12 with the rotation axis 20 inclined upward from the center of the shoe toward the outer side. Reference numeral 21 denotes an inner edge of the roller 19, which is configured such that the contact surface 15 of the frictional contact member 13 and the edge 21 come into contact with the walking surface 14 during walking. As shown in FIG. 2, an upward space portion 22 is formed between the friction contact member 13 and the inclined roller 16.

  Reference numeral 23 denotes a toe portion of the roller skate. A notch portion 24 that opens downward is formed in a portion of the friction contact member 13 at a boundary portion between the toe portion 23 and a portion on the rear side of the toe portion 23. The notch 24 is formed so that the inner part thereof is arcuate when viewed from the side of the shoe body 11. Reference numeral 25 denotes the arcuate portion. Further, the notch 24 is formed so that the opening 26 has a widened shape, that is, a groove shape when viewed from the side of the shoe body 11.

  5 to 6 show a roller skate according to another embodiment of the present invention. That is, the roller skate shown in FIGS. 1 to 4 is provided with the inclined rollers 16 at two positions on the front and rear along the length direction of the shoe body. The roller skate is provided with inclined rollers 16 at three positions on the front and rear sides. Specifically, a pair of inclined rollers 16 and 16 are provided in the toe portion 23 and the portion immediately after the toe portion 23 with the notch 24 interposed therebetween. The remaining one inclined roller is provided on the heel portion 28.

  In the roller skate shown in FIGS. 1 to 4 and the roller skate shown in FIGS. 5 to 6, the friction contact member 13 and the edge 21 of the roller 19 are both on the walking surface 14 in the state shown in FIG. 2. By making contact, the frictional contact member 13 does not move relative to the walking surface 14 due to frictional force, and thus the rotation of the roller 19 is also prevented. Thereby, it can be set as the "walking mode" which can walk similarly to the case where it walks with normal shoes. By tilting the shoe body 11 from this state, the frictional contact member 13 can be lifted from the walking surface 14 and the tread surface 27 of the roller 19 can be grounded to the running surface. Thus, the “skating mode”, that is, the “traveling mode” by the roller 19 similar to the ordinary roller skate can be set.

  The behavior of the roller skates of FIGS. 5 to 6 in the walking mode is as shown in FIG. That is, first, as shown at the right end of FIG. 7, the friction contact member 13 and the inclined roller 16 in the “heel portion 28” contact the walking surface 14, and then the entire surface of the friction contact member 13 and the entire surface are omitted although illustration is omitted. Of the inclined rollers 16, 16, 16 contact the walking surface 14. Next, by kicking up the heel, as shown in the center of FIG. As a result, the friction contact member 13 and the inclined roller 16 in the toe portion 23 remain in contact with the walking surface 14, but the rear friction contact member 13 and the inclined roller 16 are separated from the walking surface 14. Leave. At this time, as shown in the figure, the base material portion 12 constituting the shoe sole is elastically deformed into a “<” shape around the boundary between the toe portion 23 and the rear portion of the toe portion 23. To do. At this time, the frictional contact member 13 is similarly elastically deformed into a "<" shape. At this time, since the notch 24 is formed in the bent portion when the frictional contact member 13 is elastically deformed into a "<" shape, the elastic deformation aligned with the base material portion 12 can be easily performed. Can do. Accordingly, when the wearer walks, the shoe sole tends to bend in response to an operation of moving forward by kicking up the “heel portion 28” from the running surface 14, and therefore, comfortable walking in the walking mode can be realized. it can.

  Next to the operation shown in the center of FIG. 7, as shown at the left end of FIG. 7, the “toe portion 23” is moved forward by kicking up. Also at this time, the base material portion 12 is elastically deformed into a “<” shape as shown in the figure, but similarly, the friction contact member 13 is elastically deformed into a “<” shape with the notch 24 as a bending center. Therefore, the sole can be easily curved.

  The notch 24 can be formed to an appropriate depth. Alternatively, the notch portion 24 can reach the base material portion 12 so that the constituent material of the friction contact member 13 does not exist in the back portion of the notch portion 24. Alternatively, in the friction contact member 13, the inner portion of the notch 24 can be made of another material that is more easily elastically deformed than the other portions.

  8 to 10 show a roller skate according to still another embodiment of the present invention. This roller skate does not have an equivalent to the shoe main body 11 and has a configuration in which the upper surface of the base material portion 12 corresponding to the shoe sole is exposed. And the base material part 12 is provided with the belt 30, It is comprised so that the normal shoes 31 can be detachably fixed to the base material part 12 using this belt 30. FIG. According to such a configuration, it is possible to perform roller skating by fixing the shoes to the base material portion 12 in a state where any shoes are worn.

  The base material portion 12 can be adjusted in length in the shoe length direction. That is, it can be set as the structure which can be adjusted to the appropriate length according to the size of the shoes 31. FIG. According to this, it is possible to adjust the length according to the shoes 31 of all sizes by preparing about three types of “large”, “medium”, and “small” as the base material portion 12, for example. is there.

The other configuration can be the same as that of the embodiment of FIGS.
On the other hand, the embodiment shown in FIGS. 8 to 10 adopts a configuration different from that of the embodiment of FIGS. That is, a plate-like body 32 as a rigid member is fixed to the base material portion 12, and the friction contact member 13 and the inclined roller 16 are attached to the plate-like body 32. The inclined roller 16 is not inserted into the thick base material portion 12 as in the embodiment of FIGS. 1 to 7, but the bracket 18 is attached to the plate-like body 32, and the whole Is configured to protrude from the plate-like body 32. The friction contact member 13 similarly has a notch 24. Or the friction contact member 13 can also be set as the structure in which the part of the toe side rather than the notch part 24 does not exist, as shown with a virtual line in FIGS. In other words, the friction contact member 13 can be configured to be formed only in a portion on the rear side of the toe portion 23 excluding the toe portion 23.

  The plate-like body 32 can be formed of light metal, hard resin, or the like. The plate-like body 32 is configured not to exist at a boundary portion between the toe portion 23 and a portion on the rear side of the toe portion 23. That is, the plate-like body 32 is configured to have a cut 33 having an appropriate width at the boundary between the toe portion 23 and a portion on the rear side of the toe portion 23.

  According to such a configuration, the friction contact member 13 and the inclined roller 16 can sufficiently exhibit their functions by being reliably supported by the plate-like body 32. And since the plate-like body 32 has the cut line 33, the base material part 12 which comprises a shoe sole at the time of a walk uses the boundary part of the toe part 23 and the part of the back side from this toe part 23 as a bending center. It does not hinder elastic deformation in the shape of "". For this reason, the base material part 12 is easy to curve at the time of a walk, and comfortable walk in walk mode is realizable. The cut line 33 can be formed as a gap as shown in the drawing, and can be filled with a material that is easily elastically deformed, similar to the base material portion 12. Alternatively, when the plate-like body 32 is formed of resin, the boundary portion between the toe portion 23 and the rear portion of the toe portion 23, that is, the portion that bends during walking is made of a material that is easily elastically deformed. The other portions may be formed of a hard material in order to reliably support the friction contact member 13 and the inclined roller 16, and the two may be integrated.

  11 and 12 show a roller skate according to still another embodiment of the present invention. In the above-described embodiments of FIGS. 8 to 10, the configuration including the base portion 12 and the belt 30 exemplifies what can be attached to an arbitrary shoe to form a roller skate. The roller skate according to the twelfth embodiment is constructed by integrally forming the shoe main body 11 and the base material portion 12 in the same manner as shown in FIGS. Other configurations and functions thereof are the same as those in the embodiment shown in FIGS.

  1 to 12 show a roller skate in which the friction contact member 13 exists in a relatively long range other than the notch 24. However, it is sufficient that the friction contact member 13 is formed corresponding to the inclined roller 16. For example, as shown in the drawing, the friction contact member 13 is longer on the rear side than the notch 24, that is, on the “heel portion 28” side than the notch 24. It is not necessary to form continuously in the direction. In other words, if the edge 21 of the roller 19 and the frictional contact member 13 are in contact with the walking surface in the portion where the inclined roller 16 exists, it is necessary and sufficient to achieve the walking function, There is no problem even if the friction contact member 13 is not formed. Rather, it is possible to prevent the frictional contact member 13 from being formed in an unnecessary portion, which is advantageous in reducing the weight and cost of the roller skate. Moreover, the possibility that the frictional contact member 13 contacts an obstacle on the walking surface 14 can be reduced.
