Abstract

PURPOSE:To make a cleat mounting part difficult to break by walking by forming a plurality of slip preventing projections on the bottom surface of a bottom plate formed of an elastic member, and providing the cleat mounting part on the bottom surface side. CONSTITUTION:A plurality of slip preventing projections 13 are formed on the bottom surface of a bottom plate 4, and a reinforcement part 14 to a cleat mounting part 8 is provided on both lateral sides of the cleat mounting part 8. As the shoe bottom is gradually deformed against the reinforcement part 14 circumferential part, the load to the circumferential part is never collected to one point. The bottom plate 4 is partly removed to form the cleat mounting part 8 into a recessed form, and long holes 9, 9 are formed in a middle plate 6, whereby a reduction in strength of the cleat mounting part 8 itself can be suppressed. A cleat 5 never curved at the time of walking is spirally fitted with bolts 11, 11 and a nut 12, whereby a large load added to the spirally fitted part can also be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to bicycle shoes. More specifically, the present invention relates to a bicycle shoe having a plurality of anti-slip protrusions formed on the bottom surface of a sole plate formed of an elastic member, and a cleat attachment portion on the bottom surface side.

[Prior Art] Conventionally, in the above-mentioned bicycle shoes, the sole plate portion near the cleat attachment portion was not particularly reinforced and had only the same strength as the other sole plate portions.

[Problems to be Solved by the Invention] By the way, when walking with a cleat attached to the bottom of a shoe, the shoe is bent in the front and back direction, while the cleat itself is generally made of a rigid body, so Since the cleat does not bend in the front-rear direction, the load is concentrated on the attachment portion of the cleat. Therefore, when walking, the attachment part of the cleat is easily damaged, which shortens the life of the shoe, and the cleat is not attached to the pedals incompletely, causing trouble when riding the bicycle.

SUMMARY OF THE INVENTION An object of the present invention is to provide bicycle shoes whose cleat attachment portions are less likely to be damaged even when walking.

[Means for Solving the Problems] In order to achieve the above object, a first feature of the bicycle shoe according to the present invention is that anti-slip protrusions are formed at a plurality of locations on the bottom surface of the sole plate formed of an elastic member. In addition, the cleat mounting portion is provided with a cleat mounting portion on the bottom surface side, and a reinforcing portion for the cleat mounting portion is provided on at least one of the bottom plate portions of the left and right sides of the cleat mounting portion.

Also, desirably, a second characteristic configuration of the bicycle shoe according to the present invention includes, in addition to the first characteristic configuration, the reinforcing portion:
The reason is that the protrusion is formed in a thick portion that protrudes less than the protrusion.

[Function] According to the first characteristic configuration of the present invention, a reinforcing portion for the cleat mounting portion is provided on at least one of the left and right sides of the cleat mounting portion, so that the reinforcement portion for the cleat mounting portion is provided. The bottom plate portion around the cleat attachment portion becomes difficult to bend.

Therefore, even when walking, the bottom plate portion around the cleat mounting portion does not bend sharply, and the load on the cleat mounting portion is distributed around the cleat mounting portion.

Further, according to the second feature of the present invention, the reinforcing portion is formed from a thick portion, so that the reinforcing portion can be manufactured integrally with the entire bottom plate by a method such as injection molding. Manufacturing costs can be reduced. In addition, since the bottom plate is integrally formed with the reinforcing portion, the reinforcing portion rarely peels off from the boundary with the surrounding portion, resulting in insufficient functionality. Moreover, since the thick portion is formed to protrude less than the protrusion, the protrusion also protrudes from the surface of the reinforcing portion, reducing the grip force of the sole. Nor.

[Effects] As described above, according to the first characteristic configuration of the present invention, it has become possible to provide a bicycle shoe in which the cleat attachment portion is not easily damaged even when walking. Furthermore, according to the second feature of the present invention, it is possible to maintain the grip force of the sole of the shoe on the road surface and the manufacturing cost of the shoe at the same level as in the past.

It consists of

As shown in FIGS. 3 and 5, the bottom part (3) has a hard resin middle plate (6) glued to the upper side of a bottom plate (4) made of elastic resin to which the cleat (5) is attached. Furthermore, an insole (7) is placed on the upper side of the middle plate (6).

Of the sole plate (4), the portion corresponding to the area from the vicinity of the ball of the foot to the vicinity of the center of the arch is the part of the sole plate (4).
The structure is such that a concave cleat attachment part (8) can be formed by removing the lid part (4a) which is a part of the cleat attachment part (8). That is, immediately after the shoe (1) is manufactured, the concave cleat attachment portion (8) shown in FIG. 4 is integrally formed with the sole plate (4) as shown in FIGS. 1 to 3. The lid part (4
a), and these lid parts (4a)
and the bottom plate (4) are border recesses (4b) formed slightly thin.
). When using the cleat (5), after cutting with a knife or the like along the boundary recess (4b), the recessed cleat attachment portion (8) is removed by peeling off the lid (4a). can be exposed. In other words, the shoes (1) include bicycles with fixed pedals (cleats (5), which are pedaled by locking the cleats (5) attached to the bottom (3) to the pedals (P), and other bicycles.
For example, it can be used for both bicycles that do not require cleats (5), such as bicycles with toe clip attachment pedals.

The cleat (5) is attached to the middle plate (6) in the cleat mounting portion (8) with bolts (11) and (11).
, ) for attachment by two parallel slots (9)
.

(9) is formed substantially parallel to the front-rear direction of the shoe (1) from the heel to the toe. This long hole (9),
(9) is formed to be slightly wider in the lateral direction than the diameter of the bolts (11) and (11). In addition, the upper surface of the middle plate (6) of the cleat attachment part (8) is provided with the nand (12) to prevent the later-described nand (12) from coming into contact with the sole of the foot in a protruding state. ) is formed with a recess for insertion.

The cleat (

The elongated hole (5a) is inserted into the metal cylindrical piece with the hole (5a) formed therein.
Locking protrusions (5b), (5c) on both sides in the minor diameter direction of the
It is configured by providing. This cleat (5) is constructed by fitting an oval washer (10) having a longer axis shorter than the long axis of the elongated hole (5a), and attaching two bolts (10) to the washer (10). 11), (11) Two holes are inserted from the back surface of the bottom part (3) into the insertion holes (10a), (10a) and the long holes (9), (9) formed in the middle plate (6). ) (11) (11) Insert (11) into the middle plate (6) so that the locking protrusions (5b) and (5c) are aligned in the front-rear direction of the shoe (1). It is sandwiched with a gourd-shaped nut (12) and screwed together.

That is, the entire cleat (5) is inserted into the elongated hole (9).
, (9) in the front-back direction of the shoe (1), the vertical mounting position can be further adjusted to the washer (10).
), the lateral attachment position of the shoe (1) can be adjusted by sliding it in the left-right direction of the shoe (1). In this way, since the cleat (5) is directly attached to the middle plate (6), its attachment strength is much stronger than when it is attached to the bottom plate (4). In the figure, (5d) and (12a) are unevenness for preventing the cleat (5) from shifting with respect to the middle plate (6).

As shown in FIGS. 1 and 2, a plurality of anti-slip protrusions (13) are formed on the bottom surface of the bottom plate (4), and the cleat is provided on both left and right sides of the cleat mounting portion (8). A reinforcing portion (14) is provided for the mounting portion (8). This reinforcing portion (14) is integrally made of the same material as the entire sole plate (4) by a method such as injection molding, and is designed to be bent in the thumb direction most easily in the front-rear direction of the shoe (1) when walking. It is formed at a position corresponding to the vicinity, and its periphery is reinforced against bending. Since the sole gradually deforms around the reinforcing portion (14), the load on the surrounding area is not concentrated in one place.

That is, according to the above configuration, a portion of the bottom plate (4) is removed to form the cleat attachment portion (8) in a concave shape, and the middle plate (6) is provided with a long hole (9).

(9) The cleat attachment part (
8) It is possible to suppress a decrease in its own strength. In addition, cleats (5) that do not bend when walking are available) (11
), (11) and the nut (12), the heavy load placed on the screwed part can be reduced by making the bottom part (3) in the vicinity difficult to bend.

Further, the reinforcing portion (14) also has the protrusion (1) on its surface.
3) in order to protrude and suppress the decrease in grip strength of the sole.
The protrusion (13) is formed to be thick enough to protrude less than the protrusion (13). In addition, when walking with the cleat (5) attached to the cleat attachment part (8), the cleat (5)
The protrusion (13) around the cleat attachment part (8) is made to protrude downward longer than the lower surface of the cleat (5) so that it does not directly hit the ground.

Here, (E) shown in FIG. 4 is an engaging body that engages with the cleat (5) and prevents the shoe (1) from separating from the tread surface when the pedal (P) is depressed. It is. The engaging body (E) provided on this pedal (P) has locking claws (eI) and (e-) that engage with the locking protrusions (5b) and (5c) of the cleat (5), respectively, at the tip. This substantially prevents the shoe (1) from coming off. The reinforcing portions are located at the front and rear portions around the cleat attachment portion (8) so as to smoothly guide the locking body (E) to the cleat attachment portion (8) when stepping on the pedal. A guide surface (15) is provided on a part of (14) and the protrusion (13). As shown in FIG. 2, the guide surfaces (15) are arranged so that their respective surfaces relative to the cleat mounting portion (8) are inclined toward the sideways of the shoe (1) as they become further apart from the sole of the shoe. It is formed. Furthermore, when cutting the lid part (4a) with the aforementioned knife, the formation of the guide surface (15) provides a place for the knife to escape, so the knife is cut vertically and the cut surface is It can be finished beautifully.

As shown in FIG. 1, the anti-slip protrusion (13) has a first region (A) on the tip side of the shoe (1) and a second region (B) corresponding to the arch of the foot and its vicinity. and a third region (C) corresponding to the heel, each of which has a different shape, and this point will be explained below.

The first region (A) has a first protrusion (13a) formed in the shape of a key when viewed from the front, with one side parallel to the front-back direction of the shoe (1) and the other side in the front-rear direction. By arranging the shoe (1) in a staggered manner in the front-rear direction and the width direction so as to be perpendicular to the toe clip, a continuous line is formed in the side view of the shoe (1). For pedal-type bicycles, when inserting your foot into the toe clip, the pedal side plate (P
The structure is such that the first protrusion (13a) does not get caught on the edge of 2). Furthermore, the first protrusion (
The protruding length of 13a) from the surface of the sole plate (4) is determined by the length on the tip side of the shoe (1).

In the second region (B), a second protrusion (13b) that engages with an edge of the pedal side plate (P2) is arranged in a direction substantially perpendicular to the front-rear direction of the shaft (1). , as the pedal (P) is depressed, the second protrusion (
13b) engages with the edge of the pedal side plate (P), so that the shoe (1) does not slip off the pedal (P).

The third region (C), that is, the heel, includes the first protrusion (
13a) and the second protrusion (13b).
) A plurality of third protrusions (
13c) is provided. The front end of the third protrusion (13c) on the arch side is connected to a line (
12) When the front end of the third protrusion (13c) on the arch side engages with the pedal side plate (P2) when the pedal (P) is depressed. In addition, since the straight line (11) is located on a plane that is almost parallel to the rotational surface of the crank, unnatural driving in which the toe is turned outward to avoid the toe from entering inside the rotational surface of the crank is avoided. It is constructed so that there is no need to take any posture. In other words, the protrusion (13) is used to prevent slipping on the ground when it is necessary to walk on a mountain road during cycling, and is also used as a pedal (P) when riding a bicycle other than the cleat (5) fixed pedal type. and shoes (1
) is used for positioning, etc.
