Description

  The present invention relates to a slip-resistant sheet that is difficult to slip on a floor surface that is in a slippery state due to adhesion of water, oil, solvent, liquid soap, or the like, and a slip-resistant shoe using the slip-resistant sheet. .

  The floor surface to which liquids such as water, oil, solvent, soap, etc. are slippery is slippery between the sheet laid on the floor surface and the shoe sole on which the person steps, or when the sheet is not laid This is because a liquid is interposed between the floor and the floor, and slipping can be prevented by quickly discharging the liquid from the lower part of the seat or the shoe sole. Therefore, in general, a slip resistant sheet or a slip resistant shoe is provided with a groove and a protrusion for discharging liquid between the seat and the floor surface or between the shoe sole and the floor surface.

However, when a person steps on a sheet or the like, the convex portion provided on the seat or the shoe sole falls, and there is a problem that liquid easily enters between the ground surface and the floor surface of the collapsed convex portion so that it is easy to slip. Arise.
Further, if a slip resistant sheet or a slip resistant shoe is made of a hard material including the convex portion so as to prevent the convex portion from collapsing, the grip force on the convex portion surface is lowered and the slip portion becomes slippery.

Therefore, various proposals have been made on sheets and shoes in order to increase slip resistance.
As such, a slip-resistant shoe is known which has a plurality of convex portions having a V-shaped cross section and is arranged with a predetermined interval between the convex portions (for example, see Patent Document 1).
Japanese Patent No. 3959648

However, in the slip resistant shoe described in Patent Document 1, there are a direction in which the liquid in the sole can be easily drained and a direction in which the liquid is not so (there is direction dependency).
For example, the invention described in Patent Document 1 is a configuration in which convex portions having a V-shaped cross section are arranged at predetermined intervals in the foot length direction and arranged in a plurality of rows in the foot width direction. The liquid accumulates at a location surrounded by the two walls to be formed. That is, the liquid easily flows in the forward direction as the V-shaped opening, but the flow of the liquid is blocked by the wall in the remaining three directions (backward, rightward, and leftward).

  Accordingly, an object of the present invention is to provide a slip-resistant sheet having no direction dependency with respect to drainage and a slip-resistant shoe using the same for a shoe sole.

  In order to achieve the above object, the shoe according to claim 1 of the present invention uses a slip resistant sheet (8) in which a plurality of convex portions (2) are formed on the shoe sole (1). The slip resistant sheet (8) used for the shoe sole (1) has two or more linear grooves (3) formed at equal intervals in the foot width direction and parallel to the foot length direction. The plurality of protrusions (2) are formed with a substantially isosceles triangle cross section, and are in a row between two adjacent grooves (3) of the grooves (3), and the bases of the substantially isosceles triangles. Are arranged so that the protrusions (2) that are parallel to the foot length direction and adjacent to each other in the foot length direction are staggered at a predetermined interval, and that the apex is from the center of the base of the substantially isosceles triangle of the protrusion (2). A slit (4) is formed toward the corner side.

  The shoe according to claim 2 is a straight line in which the apex angle of a substantially isosceles triangle in two convex portions (2) adjacent in the foot width direction is perpendicular to the groove (3). It is arranged so that it may be located on the top.

  The shoe according to claim 3 is a straight line in which the apex angle of a substantially isosceles triangle in two convex portions (2) adjacent in the foot width direction is perpendicular to the groove (3). It is arranged so that it is not located on the top.

  The shoe according to claim 4 is a slip-resistant shoe using a slip-resistant sheet (8) in which a plurality of convex portions (2) are formed on the shoe sole (1), and the shoe sole (1). The slip resistant sheet (8) used in the present invention has two or more linear grooves (3) formed in parallel to the foot width direction at equal intervals in the foot length direction, and a plurality of convex portions ( 2) The cross section is a substantially isosceles triangle, and is in a line between two adjacent grooves (3) of the grooves (3), and the base of the substantially isosceles triangle is parallel to the foot width direction and the foot width direction. The protrusions (2) adjacent to each other are arranged so as to be staggered at a predetermined interval, and the slit (4) is formed from the center of the base in the approximately isosceles triangle of the protrusion (2) toward the apex side. It is formed.

  The shoe according to claim 5 is a straight line in which the apex angle of a substantially isosceles triangle in two convex portions (2) adjacent in the foot length direction is perpendicular to the groove (3). It is arranged so that it may be located on the top.

  The shoe according to claim 6 is a straight line in which the apex angle of a substantially isosceles triangle in two convex portions (2) adjacent in the foot length direction is orthogonal to the groove (3). It is arranged so that it is not located on the top.

  Further, in the shoe according to claim 7, the plurality of convex portions (2) are not provided between the toe side and the heel side of the slip resistant sheet (8) used for the shoe sole (1). The part (5) is formed.

  Further, in the shoe according to claim 8, the groove (3) on the toe side extends from the non-pressing part (5) with respect to the extending direction of the groove (3) on the heel side from the non-pressing part (5). The direction is inclined toward the thumb side.

  In the shoe according to claim 9, the toe side boundary line of the non-pressing part (5) is inclined so as to narrow the distance from the outside to the inside with respect to the heel side boundary line of the non-pressing part (5). It is characterized by that.

  In the shoe according to claim 10, the length of the slit (4) is set to approximately 1/3 to 2/3 of the distance connecting the center of the base of the approximately isosceles triangle of the convex portion (2) and the apex angle. It is characterized by that.

The slip-resistant sheet (8) according to claim 11 is a slip-resistant sheet (8) in which a plurality of convex portions (2) are formed on at least one side, and on one side, the longitudinal direction is equally spaced. And two or more linear grooves (3) formed in parallel in the horizontal direction are formed,
The plurality of convex portions (2) have a substantially isosceles triangle cross section, and are arranged in a row between two adjacent grooves (3) of the grooves (3), and the bases of the approximately isosceles triangles are parallel to the horizontal direction. Are arranged so as to be staggered with a predetermined interval between them, and a slit (4) is formed from the center of the base in the approximately isosceles triangle of the convex part (2) toward the apex side. It is characterized by becoming.

  Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

According to the slip resistant shoe described in claim 1, the slip resistant sheet used for the shoe sole has two or more linear grooves formed at equal intervals in the foot width direction and parallel to the foot length direction. Since the liquid is quickly discharged from the rear heel side end to the outside of the shoe sole through the groove when the user moves forward while wearing the shoes, the discharged liquid is again discharged from the shoe sole and the floor surface. I don't get in between.
As described above, since the liquid causing the slip does not remain between the shoe sole and the floor surface, an excellent slip resistant shoe can be obtained.
Further, since the convex portions are arranged in a row between two adjacent grooves, and the convex portions are arranged so as to be staggered at a predetermined interval, as shown in Patent Document 1, the liquid can be used as a shoe. There is no part that stays at the bottom. That is, the liquid smoothly flows out of the shoe sole via the gap between the groove and the convex portion, and since there is nothing that obstructs the flow of the liquid in any direction, the slip resistance is excellent.

In addition, since the convex portion is provided with a slit, even if one side of the convex portion falls down with the slit as a boundary, the other side does not fall down, so that the grip force with the floor surface can be maintained.
In addition, the liquid adhering to the ground contact surface of the convex part may flow not only directly into the groove but also into the slit, but the liquid that has entered the slit is outside the shoe sole from the groove communicating with the slit. Excellent slip resistance.

According to the slip-resistant shoe according to claim 2, in addition to the function and effect of the invention according to claim 1, the plurality of protrusions are formed at the tops of substantially isosceles triangles in two protrusions adjacent in the foot width direction. Since the corners are arranged so as to be positioned on a straight line orthogonal to the grooves, convex portions in the same direction are arranged in the foot width direction.
Thus, since the direction of a convex part is equal, compared with the thing where direction is not uniform, resistance force becomes strong with respect to the force which depresses a convex part. That is, a higher grip force can be obtained during walking, and it becomes difficult to slip.

  According to the slip-resistant shoe according to claim 3, in addition to the function and effect of the invention according to claim 1, the plurality of protrusions are formed at the tops of substantially isosceles triangles in two protrusions adjacent in the foot width direction. The corners are arranged so that they do not lie on a straight line perpendicular to the grooves. This is because the apex angles of the approximately isosceles triangles of the plurality of protrusions are different from the apex angles of the plurality of protrusions between adjacent grooves. Therefore, the entire shoe sole is not inferior in resistance to the force of depressing the convex portion. That is, as the entire shoe sole, slip resistance equivalent to that of the shoe according to claim 1 and claim 2 can be obtained.

According to the slip-resistant shoe according to claim 4, the slip-resistant sheet used for the sole is formed with two or more linear grooves formed in parallel in the foot width direction at equal intervals in the foot length direction. Therefore, when the shoe advances while wearing the shoes, the liquid is quickly discharged out of the sole from the end in the sole width direction without staying on the sole. That is, compared with the slip-resistant shoes according to claims 1 to 3, which must be discharged from the heel side end portion through a groove extending in parallel with the foot length direction, in the shoe according to this claim, at any position in the foot length direction. Even the existing liquid can be drained more quickly because it is discharged out of the sole from the width direction of the foot, which has a shorter moving distance than the length direction of the foot.
Further, similarly to the first aspect of the invention, since the convex portions are arranged in a row between two adjacent grooves, the liquid flow is obstructed in any direction. There is nothing. That is, since the liquid smoothly flows between the grooves and the convex portions arranged alternately, there is no wall portion etc. that obstructs the front, rear, left, and right directions, so that it has slip resistance.

  According to the slip resistant shoe of the fifth aspect, in addition to the function and effect of the invention of the fourth aspect, the plurality of convex portions are arranged at the tops of substantially isosceles triangles in the two convex portions adjacent in the foot length direction. Since the corners are arranged so as to be located on a straight line orthogonal to the groove, convex portions in the same direction are arranged in the foot length direction. Thus, if the direction of a convex part is equal, resistance will become strong with respect to the force which tilts a convex part rather than the direction when it is not uniform. That is, a higher grip force can be obtained during walking, and it becomes difficult to slip.

  According to the slip-resistant shoe according to claim 6, in addition to the function and effect of the invention according to claim 4, the plurality of convex portions are arranged at the tops of substantially isosceles triangles in two convex portions adjacent in the foot length direction. The corners are arranged so that they do not lie on a straight line perpendicular to the grooves. This is because the apex angles of the approximately isosceles triangles of the plurality of protrusions are different from the apex angles of the plurality of protrusions between adjacent grooves. Therefore, the entire shoe sole is not inferior in resistance to the force of depressing the convex portion. That is, as the entire shoe sole, the slip resistance equivalent to that of the shoes according to claims 4 and 5 is obtained.

  According to the slip-resistant shoe according to claim 7, in addition to the function and effect of the invention according to claims 1 to 6, a plurality of convex portions are not provided between the toe side and the heel side of the shoe sole. Since the depression is formed, half of the time is required until the liquid in the groove on the toe side is drained as compared with the case where the depression is not formed. That is, since it is not necessary to flow the liquid to the heel side end, the time for draining is shortened.

  According to the slip-resistant shoe of the eighth aspect, in addition to the function and effect of the invention of the seventh aspect, the toe side from the non-stepped portion with respect to the extending direction of the groove on the heel side from the non-stepped portion. Since the extending direction of a certain groove is inclined toward the thumb side, the gripping force is improved. That is, since the direction of the substantially isosceles triangle of the convex part on the toe side is inclined with respect to the heel side, for example, even if the convex part on the heel side falls down, the convex part on the toe side does not fall down. Overall, more slippery.

  According to the slip-resistant shoe according to claim 9, in addition to the function and effect of the invention according to claim 7 or 8, the toe side boundary line of the non-stepping part is set to the heel side boundary line of the non-stepping part. Since the gap is inclined so as to be narrowed from the outside to the inside, in the inventions according to claims 1 to 3, a boundary line perpendicular to the groove is formed, and in the inventions according to claims 4 to 6, the bottom of the groove or the convex portion is formed. Since it becomes a parallel boundary line, the impression is arranged in an orderly manner.

  According to the slip-resistant shoe according to claim 10, in addition to the function and effect of the invention according to claims 1 to 9, approximately 1 / of the distance connecting the center of the base of the approximately isosceles triangle of the convex portion and the apex angle. Since 3 to 2/3, the slit works effectively. That is, if the slit is too short, there is no effect of the slit, and if the slit is too long, the ground contact portion of the convex portion is reduced, so that it becomes slippery.

According to the slip-resistant sheet according to claim 11, since two or more linear grooves formed at equal intervals in the vertical direction and in parallel in the lateral direction are formed on at least one surface, the slip-resistant sheet is placed on the floor. When laid on the surface, the liquid is quickly discharged from the lateral end through the groove and out of the slip resistant sheet.
Further, since the convex portions are arranged in a row between two adjacent grooves so as to be staggered with a predetermined interval, there is nothing that obstructs the liquid flow in any direction. That is, the liquid smoothly flows between the grooves and the convex portions facing each other, and there is no wall portion or the like that obstructs the front, rear, left, and right directions, so that it has slip resistance.

In addition, since the slit is provided in the convex part, even if one side of the convex part falls over the slit, the other side does not fall down, so that the grip force with the floor surface can be maintained.
In addition, the liquid adhering to the ground contact surface of the convex portion may not only flow directly into the groove but also flow into the slit, but the liquid in the slit moves out of the slip resistant sheet from the groove communicating with the slit. Since it is discharged, it has excellent slip resistance.

  Note that, as in the present invention, there is no description at all in the above-mentioned Patent Document 1 regarding a configuration that has no direction dependency and can be smoothly drained in any direction.

(First embodiment)
With reference to FIG. 1 thru | or FIG. 5, the slip resistant shoes which concern on 1st embodiment of this invention are demonstrated. FIG. 1 is a plan view showing a sole 1 of a slip resistant shoe according to a first embodiment of the present invention. FIG. 2 is an enlarged perspective view of the convex portion 2 of the shoe sole 1 shown in FIG. 3A is a cross-sectional view taken along line AA in FIG. 2, and FIG. 3B is a cross-sectional view taken along line BB in FIG.

  In this shoe, a plurality of convex portions 2 are formed on the shoe sole 1 so as to be difficult to slide against the floor surface 6 which is in a slippery state due to liquid 7 such as water, oil, solvent, liquid soap, etc. The present invention relates to a slip-resistant shoe using a slip-resistant sheet 8 (shown in FIG. 8 to be described later), and the shoe sole 1 mainly includes a convex portion 2, a groove 3, a slit 4, and a tread portion 5.

The tread portion 5 is formed in a so-called arch portion between the toe side and the heel side of the shoe sole 1 from the left end to the right end in the foot width direction. That is, the plurality of convex portions 2 are not provided here.
The heel side boundary line of the tread portion 5 is parallel to the foot width direction, and the toe side boundary line of the tread portion 5 extends from the outer side of the shoe sole 1 to the inner side with respect to the heel side boundary line of the tread portion 5. It is inclined to narrow the interval.

The groove 3 is formed in the shoe sole 1 in two or more straight lines formed at equal intervals in the foot width direction and parallel to the foot length direction. Each groove 3 is connected from the toe side end of the shoe sole 1 to the boundary line with the treadle part 5 and from the heel side end part to the boundary line with the treadle part 5. There is no barrier to block the flow of liquid 7.
However, the groove 3 on the heel side from the non-stepping portion 5 is parallel to the foot length direction, but the extending direction of the groove 3 on the toe side from the non-stepping portion 5 is the groove 3 on the heel side from the non-stepping portion 5. It is inclined to the thumb side with respect to the extending direction.

Further, the width of the groove 3 itself is the same regardless of the heel side from the non-stepping portion 5 and the toe side from the non-stepping portion 5. In addition, the adjacent grooves 3 are all equal in the same manner.
In addition, the inner surface of the groove 3 on the shoe sole 1 side is the same height as the tread portion 5 with respect to the thickness direction of the shoe sole 1.

The plurality of convex portions 2 are substantially isosceles triangles in cross section, and the substantially isosceles triangles are congruent, and the foot width direction height of the approximately isosceles triangle is equal to the interval between adjacent grooves 3. Among the two adjacent grooves 3, the bases of the isosceles triangles are arranged in parallel so that the convex portions 2 that are parallel to the foot length direction and adjacent to each other in the foot length direction are staggered at a predetermined interval. Yes. That is, when the foot width direction is the left-right direction, the convex part 2 adjacent to the toe side of the convex part 2 has a vertical angle with respect to the base, with respect to the convex part 2 whose apex angle is on the right side with respect to the base. It is the convex part 2 on the left side. Next, the convex part 2 adjacent to the toe side is the convex part 2 with the apex angle on the right side with respect to the base.
Here, the predetermined interval is substantially equal to the width of the groove 3.

The arrangement pattern of this convex part 2 is repeated from the toe side end of the shoe sole 1 to the boundary line with the treadle part 5 and from the heel side end part to the boundary line with the treadle part 5, and all A similar arrangement pattern is repeated between adjacent grooves 3.
However, at the outer peripheral end portion of the shoe sole 1, the arrangement pattern of the convex portions 2 is divided by the outline of the shoe sole 1, and the convex portions 2 are not substantially isosceles triangles at the divided portions.
In addition, the apex angles of the approximately isosceles triangles in the two convex portions 2 adjacent to each other with the groove 3 in the foot width direction are arranged on a straight line orthogonal to the groove 3. That is, the opposite side of the apex-angle groove 3 of the approximately isosceles triangle that is vertically separated is arranged to be the center of the base of the approximately isosceles triangle that is adjacent in the foot width direction.

  The side wall surface of the convex portion 2 is perpendicular to the shoe sole 1 except for the root portion. On the other hand, the base portion of the convex portion 2 has a side wall surface of the convex portion 2 that extends toward the shoe sole 1, which is a convex portion when the shoe sole 1 is taken out from the mold in the production process of the shoe sole 1. In order to prevent 2 from being broken and remaining in the mold, the edge of the mold is chamfered, which is well known among the parties (see FIG. 3).

Moreover, the convex part 2 forms the slit 4 toward the vertex side from the base of the substantially isosceles triangle.
The length of the slit 4 is approximately ½ of the distance connecting the center of the base of the isosceles triangle of the convex portion 2 and the apex angle, and the width of the slit 4 is approximately ½ of the width of the groove 3. The depth of 4 is equal to the height of the convex portion 2. The slit 4 communicates with the groove 3 at the center of the base.

  This slip resistant shoe has a slip resistant function as follows. This will be described with reference to FIG. 4, (a) shows how the liquid 7 flows toward the heel side of the sole 1 of the slip resistant shoe shown in FIG. 1, and (b) shows the toe of the sole 1 of the slip resistant shoe shown in FIG. (C) shows the flow of the liquid 7 flowing toward the side, and (c) shows the flow of the liquid 7 flowing toward the right end (right side in FIG. 4) of the sole 1 of the slip resistant shoe shown in FIG. ) Shows how the liquid 7 flows toward the left end (left side in FIG. 4) of the sole 1 of the slip resistant shoe shown in FIG.

When the liquid 7 interposed between the shoe sole 1 and the floor surface 6 flows toward the heel side, the liquid 7 flows from the toe side in the groove 3 toward the heel side. The liquid 7 in the space between the convex portions 2 that are alternately arranged in a row between the adjacent grooves 3 flows toward the heel side oblique direction and merges with the flow of the grooves 3 (see FIG. 4A). . At this time, since there is no barrier that obstructs the flow of the liquid 7, it flows smoothly.
When it flows toward the toe side, it is 180 ° opposite to when it flows toward the heel side, and therefore flows smoothly in the same manner (see FIG. 4B).

On the other hand, when the liquid 7 interposed between the shoe sole 1 and the floor surface 6 flows toward the right end portion, the liquid 7 in the groove 3 is discharged out of the shoe sole 1 from the toe side end portion and the heel side end portion. The The liquid 7 within the interval between the convex portions 2 that are alternately arranged in a row between the adjacent grooves 3 flows to the groove 3 that communicates with the right side of the space (see FIG. 4C). Similarly, at this time, since there is no barrier that hinders the flow of the liquid 7, it flows smoothly.
When flowing toward the left end, it is 180 ° opposite to when flowing toward the right end, and thus flows smoothly in the same manner (see FIG. 4D).
Thus, since the convex part 2 of a substantially isosceles triangle is arrange | positioned alternately at predetermined intervals, there is no direction dependence in drainage. That is, the slip resistance has no direction dependency.

  Further, since the tread portion 5 is provided, it is not necessary to discharge the liquid 7 interposed in the toe portion to the heel side end surface. That is, since the moving distance of the liquid 7 until discharge becomes short, it can discharge quickly.

Further, when the user walks while wearing the shoes, the convex portion 2 to which the load is applied is deformed so as to fall down. This will be described with reference to FIG. In FIG. 5, (a) is an enlarged sectional view showing a state at the time of deformation when the convex portion 2 of the slip resistant shoe does not have the slit 4, and (b) is a slit 4 in the convex portion 2 of the slip resistant shoe. It is an expanded sectional view which shows the mode at the time of a deformation | transformation of the convex part 2 of the slip resistant shoes shown in FIG.
As described above, the liquid 7 enters between the ground surface 6 and the floor surface 6 of the convex part 2 that has fallen, causing a slip (see FIG. 5A). When 4 is provided, even if one side of the convex portion 2 falls down with the slit 4 as a boundary, the other side does not fall down, so that the grip force with the floor surface 6 can be maintained (see FIG. 5B). .

In addition, the presence of the slit 4 causes the liquid 7 attached to the ground contact surface of the convex portion 2 to flow not only directly into the groove 3 but also into the slit 4, but the liquid 7 in the slit 4 Since the liquid is discharged out of the shoe sole 1 through the groove 3 communicating with the slit 4, the liquid causing the slip does not remain in the slit 4. .
In addition, since the direction of the substantially isosceles triangle of the convex portion 2 is different between the toe side and the heel side from the non-stepped portion 5, it is assumed that a force that tends to fall, for example, is applied to the convex portion 2 on the heel side. The convex part 2 on the side is difficult to fall down and slip easily.

(Second embodiment)
Next, with reference to FIG.2, FIG6 and FIG.7, the slip resistant shoes which concern on 2nd embodiment of this invention are demonstrated. FIG. 2 is an enlarged perspective view of the convex portion 2 of the shoe sole 1 shown in FIG. FIG. 6 is a plan view showing the sole 1 of the slip-resistant shoe according to the second embodiment of the present invention. FIG. 7 shows the flow direction of the liquid. (A) shows the flow of the liquid 7 flowing toward the heel side of the sole 1 of the slip resistant shoe shown in FIG. 6, and (b) shows the slip resistant shown in FIG. (C) shows the flow of the liquid 7 flowing toward the right end of the sole 1 of the slip resistant shoe shown in FIG. (D) shows how the liquid 7 flows toward the left end of the sole 1 of the slip resistant shoe shown in FIG.

  The angle of the boundary line between the first embodiment, the position of the tread portion 5 and the convex portion 2 is the same. The positional relationship between the groove 3 and the convex portion 2 is the same as that in the first embodiment. However, the positional relationship between the shoe sole 1 and the groove 3 or the convex portion 2 is different from that of the first embodiment, and the arrangement of the first embodiment on the toe side from the non-stepping portion 5 and on the heel side from the non-stepping portion 5. The pattern is rotated 90 °.

The difference in effect from the first embodiment is as follows.
When the liquid 7 is discharged, in the shoe according to the present embodiment, the liquid 7 is quickly discharged from the end in the foot width direction of the shoe sole 1 to the outside of the shoe sole 1. That is, in the shoe according to the present embodiment, the shoe according to the present embodiment is present at any position in the foot length direction as compared with the slip resistant shoe of the first embodiment that must be discharged from the heel side end portion through the groove 3 extending parallel to the foot length direction. The liquid 7 can also be drained more quickly than the slip resistant shoes of the first embodiment because the liquid 7 is discharged out of the shoe sole 1 from the width direction of the foot, which is shorter than the length direction of the foot. That is, the slip resistance is more excellent.

  Moreover, since the arrangement | sequence pattern of the convex part 2 only rotated the arrangement pattern of 1st embodiment 90 degrees, there is no direction dependence in drainage property similarly to 1st embodiment. That is, the slip resistance has no direction dependency (see FIG. 7).

  Note that the effect of the slit 4 and the effect that the direction of the substantially isosceles triangle of the convex portion 2 is inclined on the toe side and the heel side from the tread portion 5 are equal to those of the first embodiment.

(Third embodiment)
Next, with reference to FIG.2 and FIG.8, the slip resistant sheet 8 which concerns on 3rd embodiment of this invention is demonstrated. FIG. 2 is an enlarged perspective view of the convex portion 2 of the slip resistant sheet 8 shown in FIG. FIG. 8 is a plan view showing the slip resistant sheet 8 according to the third embodiment of the present invention.
This slip-resistant sheet 8 relates to the slip-resistant sheet 8 that is difficult to slide with respect to the floor surface 6 that is in a slippery state with a liquid 7 such as water, oil, solvent, liquid soap, etc. attached thereto. The arrangement pattern of the groove | channel 3 and the convex part 2 in the shoe sole 1 of the shoe which concerns on 2nd embodiment is the same. However, unlike the shoe sole 1, the tread portion 5 is not provided.

  Since this arrangement pattern is applied to both the front and back surfaces of the slip resistant sheet 8, the slip resistance between the floor surface 6 and the slip resistant sheet 8 and between the slip resistant sheet 8 and the shoes is maintained. That is, if the slip-resistant sheet 8 is laid on the floor surface 6, slip resistance can be obtained even if existing shoes are used. Moreover, since the isosceles triangular convex portions 2 are alternately arranged at a predetermined interval as in the shoes according to other embodiments, the drainage property, that is, the slip resistance has no direction dependency. Note that the slip resistance effect can be obtained only by applying this arrangement pattern to either the front or back of the slip resistant sheet 8.

In addition, as for the arrangement | sequence of the convex part 2 of the slip resistant shoes which concerns on 1st thru | or 3rd embodiment, or the slip resistant sheet 8, the vertex angle of the substantially isosceles triangle of the convex part 2 is all the same on the straight line orthogonal to the groove | channel 3. However, the present invention is not limited to this, and the apex angles aligned on this straight line may face each other across the groove 3.
Alternatively, the apex angles of the substantially isosceles triangles of the plurality of convex portions 2 can be arranged so as not to be positioned on a straight line orthogonal to the groove 3.

It is a top view showing the sole of the slip resistant shoes concerning a first embodiment of the present invention. It is an expansion perspective view which shows a some convex part. (A) is the sectional view on the AA line of FIG. 2, (b) is the sectional view on the BB line of FIG. (A) shows the flow of the liquid flowing toward the heel side of the sole of the slip resistant shoe shown in FIG. 1, and (b) shows the liquid flowing toward the toe side of the sole of the slip resistant shoe shown in FIG. (C) shows the flow of liquid flowing toward the right end of the sole of the slip resistant shoe shown in FIG. 1, and (d) shows the left end of the sole of the slip resistant shoe shown in FIG. It is a top view which shows the way of the flow of the liquid which flows toward each. (A) is an expanded sectional view at the time of a deformation | transformation when the convex part of slip resistant shoes does not have a slit, (b) is an expanded sectional view at the time of a deformation | transformation when the convex part of slip resistant shoes has a slit.
