BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a baby shoe and more particularly, it
relates to a baby-friendly baby shoe.
Description of the Background Art
Baby shoes are used from an early stage of walking of a baby, which is
for the purpose of protecting feet of the baby.
It is said that a foot of a child starts to grow from about one year old
when a baby starts to walk until six or seven years old. Especially, it is
important to develop the foot in a healthy manner in a relatively early stage
of growth.
Fig. 1 shows a baby shoe for a toddling baby disclosed in Japanese
Unexamined Patent Publication No. 47-8680. An illustrated baby shoe 1
comprises a sole part 2 positioned under the baby foot, a tongue part 3
covering the baby instep, a first side coat part 4 covering one side face of the
baby foot and partially overlapping with the tongue part 3, and a second
side coat part 5 covering the other side face of the baby foot and partially
overlapping with the tongue part 3.
The first side coat part 4 and the second side coat part 5 each have
edges opposed to each other over the tongue part 3, and holes through which
a shoelace passes are provided at the edges. The shoelace (not shown)
passing through the holes connects the first side coat part 4 and the second
side coat part 5 over the tongue part 3 to hold the foot of the baby.
In the case of the baby shoe shown in Fig. 1, the following problems
have been pointed out, for example.
(1) The side coat part 4 and the tongue part 3 are sewed together in a
region away from the toe of the shoe 1, which is shown by A in Fig. 1.
When the foot of the baby is put into the shoe, the tongue part 3 is turned up
forward. However, it cannot be turned up at a part positioned ahead of the
region A. Therefore, an opening through which the foot is inserted cannot
be largely opened. Since the baby foot is flexible and soft, when the foot is
inserted into the shoe through the opening which is not large enough, the
baby could feel pain at that time. (2) An uneven part appears because of overlapping of the side coat
part 4 and the tongue part 3 and also a seam of them appears. The uneven
part and the seam part are positioned at a place corresponding to the top of
the metatarsal bone of the baby. Since the baby foot is soft and fat, a width
of the foot widens when the weight is put thereon in walking. Especially,
the top of the metatarsal bone is a part which widens most of all when the
baby puts the weight on the foot in walking. In the case of the baby shoe
shown in Fig. 1, since the uneven part and the seam part abut on the
widening part of the foot, the soft baby foot could be damaged. (3) The soft instep of the baby widens when the weight is put thereon
and heightens when the foot is in the air. In walking, the state the weight
is put on the foot on the ground and the state the foot is in the air are
repeated. Therefore, when the part of the instep is strongly pressed at the
tongue part 3 from above by strongly fastening the first side coat part 4 and
the second side coat part 5 with the shoelace, the instep is pressed hard in
walking. (4) In the case of the shoe shown in Fig. 1, the first side coat part 4 and
the second side coat part 5 have a height extending close to the ankle of the
baby putting on the shoe 1. Since the ankle of the toddling baby is shaky
especially, it is necessary to hold the ankle stably by fastening the shoelace
tight. However, when the ankle is held stably, since the first side coat part
4 and the second side coat part 5 press the anklebone of the baby strongly,
the baby feels pain at the anklebone. In addition, when the anklebone is
fastened strongly, the smooth movement of the ankle is hindered.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a baby shoe devised
so as not to damage a soft baby foot.
The present invention provides a baby shoe comprising a sole part
positioned under the baby foot, a tongue part covering the baby instep, a
first side coat part covering one side face of the baby foot and partially
overlapping with the tongue part, and a second side coat part covering the
other side face of the baby foot and partially overlapping with the tongue
part 22, and it is characterized by the following points.
That is, a front end of the tongue part is connected to a front end of the
sole part. The first and the second side coat parts each have edges which
are opposed to each other over the tongue part. Each of the edge parts of
the first and the second side coat parts is positioned over the tongue part
and extends to the front end of the sole part. In each of the edge parts of
the first and the second side coat parts, its front part close to the front end
of the sole part is sewed on the tongue part.
Preferably, seams of the edges of the first and the second side coat
parts, and the tongue part are positioned over the toes of the baby putting
on the shoe.
According to one embodiment, there is provided a connection band
connecting the edge of the first side coat part and the edge of the second side
coat part. The connection band has one end connected to an inner face of
the first side coat part and the other end detachably connected to an outer
face of the second side coat part.
There may be a plurality of connection bands. More specifically, the
baby shoe comprises a first, a second and a third connection bands
connecting the edge of the first side coat part and the edge of the second side
coat part. The first connection band is positioned apart from the ankle, the
third connection band is positioned closest to the ankle and the second
connection band is positioned in the middle. Each of the first, second and
third connection bands has one end connected to an inner face of the first
side coat part and the other end detachably connected to an outer face of the
second side coat part.
According to another embodiment, a baby shoe comprises a first and a
second connection bands connecting the edge of the first side coat part and
the edge of the second side coat part. The first connection band is
positioned apart from the ankle and has one end connected to an inner face
of the first side coat part and the other end detachably connected to an outer
face of the second side coat part. The second connection band is positioned
close to the ankle and has one end connected to the inner face of the first
side coat part and the other end detachably connected to the outer face of
the second side coat part.
Preferably, means for detachably connecting the other end of the
connection band and the outer face of the second side coat part is a surface
fastener.
Preferably, a grip band picked with fingers is attached to a back face
part of the baby shoe. The grip band has a lower end fixed to the shoe and
an unfixed grip part length is 2cm or more. According to one embodiment,
a height of an upper end of the grip band is the same as a height of an upper
end of the baby shoe or less.
A meritorious effect of above each component is described in a section
of the description of the embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 2 is an anatomical drawing of the bone of the foot. The bone of
the foot mainly consists of three regions such as a phalanx (toe bone) region
B, a metatarsal region C and a tarsal region D. A metatarsal arch 10 at
the front of the foot is a so called instep arch which is not a real arch and
changes when stress is applied. In a case of an adult, the metatarsal arch
10 disappears in walking by weight. A lateral arch 11 at the tarsal does
not change by weight in the case of the adult.
Since the foot of a baby is soft and fat, the shape of the foot changes
when the weight is put on the foot on the ground and when the foot leaves
the ground. When the weight is put on the foot, a width of the foot is
increased and a height of the instep is decreased. In the meantime, when
the foot leaves the ground and it is in the air, the width of the foot is
decreased and the height of the instep is increased.
The baby bends the toes to catch the ground while standing. To
promote this motion leads to shaping of the arc of the foot. In order to
smoothly perform this motion by the toes, it is necessary to stably hold the
metatarsal arch 10. Since the metatarsal arch 10 does not limit the
movement of the toes, the movement of the toes is not hindered even if it is
stably fixed.
The region of the lateral tarsal arch 11 decides the height of the instep
and in the case of the baby, it heightens when the weight is not put on.
Therefore, this part should not be held tight.
Since the skin of the baby is soft, it is likely to be damaged by
roughness or rubbing. In addition, in the case of the baby who just begins
walking, since the ankle is shaky, it is necessary to stably hold the ankle in
order to promote the smooth walking.
The present invention was made in view of the above-described foot
structure peculiar to the baby and provides a baby shoe devised so as not to
damage the soft baby foot.
Figs. 3 through 6 show an embodiment of the present invention. Fig.
3 is a perspective view, Fig. 4 is a front view, Fig. 5 is a side view and Fig.6
is a perspective view showing a state in which an opening for inserting the
foot is widely open.
An illustrated baby shoe 20 comprises a sole part 21 positioned under
the baby foot, a tongue part 22 covering the baby instep, a first side coat
part 23 covering one side face of the baby foot and partially overlapping
with the tongue part 22, and a second side coat part 24 covering the other
side face of the baby foot and partially overlapping with the tongue part 22.
The first and the second side coat parts 23 and 24 are continuously formed
through a back face of the shoe 20.
A front end of the tongue part 22 is connected to a front end 21a of the
sole part 21. The first and the second side coat parts 23 and 24 have edge
parts 23a and 24a, respectively which are opposed to each other over the
tongue part 22. As shown in the drawings, the edge parts 23a and 24a of
the first and the second side coat parts 23 and 24 extend to the front end
21a of the sole part 21 while positioned over the tongue part 22.
In each of the edge parts 23a and 24a of the first and the second side
coat parts 23 and 24, its front part close to the front end 21a of the sole part
21 is sewed on the tongue part 22. In Figs. 3 through 6, a part shown by E
is a part in which each of the side coat parts 23 and 24 is sewed on the
tongue part 22.
There are an uneven part because of the overlapping of each of the
side coat parts 23 and 24 and the tongue part 22, and a seam part between
them, inside the baby shoe 20. Although the uneven part and the seam
part are positioned at the top of the metatarsal bone of the baby in the
conventional baby shoe shown in Fig. 1, according to the baby shoe in this
embodiment of the present invention, the uneven part and the seam part E
are positioned over the toes of the baby. According to this embodiment of
the present invention, even when the weight is put on the foot of the baby,
since the uneven or the seam part E does not rub on the toes, the baby foot
is not damaged.
Furthermore, as shown in Fig. 6, according to this embodiment of the
present invention, since the edge parts 23a and 24a of the first and the
second side coat parts 23 and 24 extend to the front end of the sole part 21
and sewed on the tongue part 22 at a region close to this front end, the
tongue part 22 can be largely turned up to near the front end of the sole part
21. Therefore, since the opening for inserting the foot can be largely
opened, the soft baby foot can be easily put into the shoe.
Still further, when the tongue part 22 is turned up to near the front
end 21a of the sole part 21, since the position of the toe bone of the baby in
the shoe 20 can be confirmed, it is easy to determine whether a foot size of
the growing baby fits a size of the shoe. Thus, according to this
embodiment of the present invention, it is easy to find out time to renew
shoes.
As can be clear from Figs. 3 through 6, the edge parts 23a and 24a of
the first and the second side coat parts 23 and 24 positioned over the tongue
part 22 are connected to each other through connection bands. In this case,
one end of the connection band is fixed to an inner face of the first side coat
part 23 and the other end thereof is detachably connected to an outer face of
the second side coat part 24.
More specifically, the baby shoe 20 comprises a first connection band
25, a second connection band 26 and a third connection band 27 which
connect the edge part 23a of the first side coat part 23 to the edge part 24a
of the second side coat part 24. The first connection band 25 is positioned
apart from the ankle, the third connection band 27 is positioned closest to
the ankle and. the second connection band 26 is positioned in the middle.
As shown in the drawings, each of the first, the second and the third
connection bands 25, 26 and 27 has one end fixed to the inner face of the
first side coat part 23 and the other end detachably connected to the outer
face of the second side coat part 24.
Preferably, means for detachably connecting the other end of the
connection band is a surface fastener 31. In the case of the surface
fastener 31, the connection band can be easily connected and disconnected
for a short time. Since its operation is very simple, even the baby can
easily connect and disconnect the connection band.
According to this embodiment of the present invention, since one end
of each of the connection bands 25, 26 and 27 is positioned in the inner face
of the first side coat part 23 and the other end thereof is positioned in the
outer surface of the second side coat part 24, it is easy to distinguish a right
shoe from a left shoe. This distinction between the right and left shoes
becomes an important element in a stage the baby grows up and puts on the
shoes alone.
In addition, Figs. 3 through 6 show the shoe for the left foot and in
each of the connection bands 25, 26 and 27, one end thereof positioned at
the inner side of the foot is fixed to the inner face of the first side coat part
23 and the other end thereof positioned at the outer side of the foot is
detachably connected to the outer face of the second side coat part 24. This
relation is the same in the case of the shoe for the right foot although it is
not shown.
Although the three connection bands 25, 26 and 27 have the same
connecting forms in the illustrated embodiment, they may be differentiated.
For example, in the case of the baby who just begins walking, since the
ankle is shaky, it is necessary to stably hold the ankle. Therefore, with
regard to the connection band 27 which is closest to the ankle, its one end is
fixed to the outer face of the first side coat part 23 and the other end thereof
is detachably connected to the outer face of the second side coat part 24.
According to such connection band 27, since an upper end of the first side
coat part 23 can be pulled tight, the ankle can be held stably. With regard
to the rest of the two connection bands 25 and 26, one ends thereof are fixed
to the inner face of the first side coat part 23, so that distinction between the
right and left shoes can be easily made.
As clearly shown in Fig. 5, a grip band 30 to be picked with fingers is
attached to the back face of the baby shoe 20. When a parent has the baby
put on the shoe, a back part of the shoe 20 can be pulled up by picking this
grip band 30. Although the baby shoe provided with this kind of grip band
has been provided in the market conventionally, a length (width) of the grip
part which is not fixed is small in general and it is sometimes difficult to
pinch it. Thus, according to the embodiment of the present invention, in
order to easily pinch it with fingers, the width of the grip band 30 (the
length of the grip part which is not fixed) is set at 2cm or more. In addition,
in order not to spoil the designed beauty, an upper end of the grip band 30 is
preferably the same as a height of an upper end of the baby shoe 20 or less.
In the case of the baby who is immature in walking, since the ankle is
weak, it is desirable that the shoe can stably hold the ankle. According to
the baby shoe 20 shown in Figs. 3 through 6, in order to hold the ankle of
the baby, the first side coat part 23 and the second side coat part 24 have a
height so that the ankle of the baby can be covered.
Meanwhile, the term "ankle" used in this specification means the
thinnest part in the leg from the knee to the foot and the anklebone is
positioned just under the ankle.
According to this embodiment of the present invention, the first
connection band 25 is positioned over the metatarsal arch 10 (referring to
Fig. 2) of the baby putting on the shoe 20 so as to hold the metatarsal arch
10 tight. The second connection band 26 is positioned over the lateral
tarsal arch 11 (referring to Fig. 2) of the baby so as to fasten the lateral
tarsal arch 11 gently.
When the first connection band 25 is fasten tight to hold the
metatarsal arch 10 stably, since the baby can smoothly move the toes to
catch the ground, the formation of the arch of the foot can be promoted.
As described above, the region of the lateral tarsal arch 11 is a part in
which the height of the instep is determined. Since the baby foot is flexible
and fat, it laterally widens when the weight is put on the foot while the
height of the instep is increased when the weight is not put on the foot.
Since the configuration of the foot repeatedly changes as described above
while walking, the lateral tarsal arch 11 should not be fastened tight.
Meanwhile, when the lateral tarsal arch 11 is not held at all, the foot shifts
in the shoe and the walking is hindered. Thus, it is necessary to hold the
lateral tarsal arch 11 by the connection band 26 to some extent.
Preferably, the
connection band 26 positioned over the lateral
tarsal
arch 11 is constituted such that the lateral
tarsal arch 11 is to be fastened
only gently. For example, the following structures can be considered.
(1) By appropriately selecting the position of the surface fastener 31,
the lateral tarsal arch 11 can be fastened only gently when connected. (2) In the case the position of the surface fastener is set at the same
position as the other connection bands 25 and 27, the lateral tarsal arch 11
is to be fastened only gently by increasing the length of the second
connection band 26. (3) The second connection band 26 is widened and an opening is
provided at a part just above the lateral tarsal arch 11 so that the lateral
tarsal arch 11 may not be pressed hard. (4) The second connection band 26 is formed of a relatively hard
material so as to be convexly curved so that the lateral tarsal arch 11 may
not be pressed hard.
In the case of the baby shoe 20 shown in Figs. 3 through 6, the third
connection band 27 connects the edge part 23a of the first side coat part 23
to the edge part 24a of the second side coat part 24 at the part of the ankle
of the baby. In the case of the baby who is immature in walking, since the
ankle is shaky, it is necessary to stably hold the ankle. Thus, the third
connection band 27 is provided so as to be able to hold the ankle of the baby
stably. In order to increase fastening force of the third connection band 27
around the ankle, unlike the illustrated embodiment, one end of the third
connection band 27 may be fixed to the outer face of the first side coat part
23.
The first side coat part 23 and the second side coat part 34 have a
height so that the ankle of the baby may be covered. Therefore, when the
third connection band 27 is fastened tight to hold the ankle stably, the first
and the second side coat parts 23 and 24 abut on the anklebone of the baby.
Since the walking movement of the baby sways more than that of the adult,
if the side coat part of the shoe presses hard the anklebone of the baby who
just begins walking, the anklebone could be damaged and the walking is
hindered.
Thus, according to this embodiment of the present invention, the first
and the second side coat parts 23 and 24 have soft cushion materials 28 and
29, respectively which cover the anklebone of the baby putting on the shoe
20. Each of the cushion materials 28 and 29 has a width dimension in
which a lower end 29a (referring to Fig. 5) thereof is positioned under the
anklebone of the baby and an upper end thereof is positioned at the height
of the anklebone of the baby.
When each of the cushion materials 28 and 29 has the above width
dimension, since the anklebone of the baby can be completely covered with
the soft cushion materials, the anklebone is not damaged and the walking is
not hindered.
According to the illustrated embodiment, the cushion materials 28 and
29 are continuously formed in a whole upper end region of the first and the
second side coat parts 23 and 24. In addition, the above-described third
connection band 27 connects the cushion material 28 of the first side coat
part 23 to the cushion material 29 of the second side coat part 29 over the
tongue part 22.
In addition, in order to completely cover the anklebone, as shown in
Fig. 5, it is preferable that a part positioned under the anklebone in the
lower edge 29a of the cushion material is convexly curved downward.
Some of the conventional baby shoe have a cushion material
positioned over the anklebone. However, since a width dimension of the
cushion material is small, it seems that the anklebone is not completely
covered. According to this embodiment of the present invention, in order
to completely cover the anklebone, when it assumed that a height of the
first and the second side coat parts in the region corresponding to the
anklebone of the baby is H, the width dimension of the cushion material 29
in this region is preferably set at H/3 or more.
Figs. 7 through 9 show another embodiment of the present invention.
An illustrated baby shoe 40 comprises a sole part 41, a tongue part 42, a
first side coat part 43, and a second side coat part 44, a seam region E, a
first connection band 45, a second connection band 46, cushion materials 47
and 48, and a grip band 49. Unlike the embodiment shown in Figs. 3
through 6, the illustrated baby shoe 40 has only two connection bands 45
and 46. With Regard to other components, there is no substantially
difference.
The first connection band 45 is positioned over the metatarsal arch 10
(referring to Fig. 2) of the baby and provided so as to be able to stably hold
the metatarsal arch 10. The second band 46 is positioned over the lateral
tarsal arch 11 of the baby and provided so as to fasten the lateral tarsal arch
gently.
Since the ankle is weak until the toddling baby masters how to walk,
the baby shoe 20 shown in Figs. 3 through 6 is preferable. In the
meantime, at a stage where the baby has got used to walking, since the
ankle is stable, it is not necessary'to hold the ankle. At this stage, the baby
shoe 40 shown in Figs. 7 through 9 can be used:
Although the present invention was described with reference to the
drawings above, the present invention is not limited to the illustrated
embodiments only. Various modifications and variations can be added in
the same or an equivalent range of the present invention.
