Description
TECHNICAL FIELD
[0001] The present invention relates to a roller stake which is
detachably engaged at shoes, and in particular to a roller skate
which consists of two wheels, and width can be freely adjusted, and
shoes can be detached when needed irrespective of the sizes of
feet, and the wheels are fixed at a lower side when used, and the
wheels are fixed at an upper side when not used by allowing the
wheels to move up and down.
BACKGROUND ART
[0002] A conventional roller skate consists four rollers which
slide on a floor and are fixed at a lower surface of a roller skate
shoe. In another example of the conventional art, a plurality of
rollers is installed in an inline type at a lower surface of a
roller shake shoe for enhancing a speed and balance.
[0003] According to the above conventional roller skate, a user
wears roller skate shoes with straps being tied and runs at high
speed with a balanced posture for thereby enjoying the
exercise.
[0004] In the conventional roller skate, since a plurality of
rollers are fixed at a roller skate, when the feet sizes are not
correctly fit at the roller skate shoes, it is impossible to wear
the shoes. So, a roller skate which well fits with the foot size is
needed.
[0005] When the foot size is not well fit with the roller skate
shoe, it is impossible to wear. When the user wears larger roller
sake shoes, the user may have blister in his foot or may feel pain
for thereby causing a safety accident. In the case of children
whose feet grow every second, it is impossible to use the roller
skate for a desired long time period since their growing feet do
not fit with the fixed sizes.
[0006] In the conventional roller skate have many rollers and a
structure for fixing the rollers, so that the volume is too big for
thereby causing many inconveniences. When the rollers are worn and
need repairs, the maintenance cost increases.
[0007] In addition, when the use of the roller skate is finished,
the user is needed to change and wear the shoes. The unworn roller
skates should be stored. In this case, the volume of the stored
roller skates is too big to easily move or store the roller
skates.
DISCLOSURE OF THE INVENTION
[0008] Accordingly, it is an object of the present invention to
overcome the above-described conventional problems.
[0009] It is another object of the present invention to provide a
roller skate in which two wheels are provided, and width can be
freely adjusted, and the wheels can be detachably attached to a
rear side of a shoe with a band, and the wheels are moved down when
used, and the wheels are moved up when not used by allowing the
wheels to rotate up and down. So, when not used, the user can walk
like the shoes are worn in real. The movement and wearing are easy,
and the size can be freely adjusted, and it is very easy to start,
run and stop.
[0010] To achieve the above objects, there is provided a roller
skate characterized in that a first side plate 10a having a female
engaging part 11a and a second side plate 10b having a male
engaging part 11b engaged with the female engaging part 11a are

side plate 10b are engaged, and a footrest 20 is inserted into the
female and male engaging parts 11a and 11b. When a user uses the
roller skate, it is needed to rotate down the rear side of the
roller skate, the footrest 20 contacts with the ground for thereby
obtaining a braking function.
[0023] A guide hole 16 is formed at both sides of the female
engaging part 11a, and an adjusting nut 17 is provided between the
guide holes 16.
[0024] A guide rod 18 inserted into the guide holes 16,
respectively, is formed at both sides of the male engaging part
11b, and an adjusting bolt 19 is rotatably provided between the
guide rods 18 and is engaged with the adjusting nut 17.
[0025] The guide rod 18 of the male engaging part 11b is movably
engaged in the guide hole 16 of the female engaging part 11a. The
adjusting bolt 19 of the male engaging part 11b is thread-engaged
with the adjusting nut 17 of the female engaging part 11a, so that
it is possible to adjust the intervals between the first and second
side plates 10a and 10b based on the rotation of the adjusting bolt
19.
[0026] Circular guide pieces 12a and 12b are formed at each side of
the first and second side plates 10a and 10b, and first fixing
holes 13a and 13b and second fixing holes 14a and 14b are formed at
the upper sides of the guide pieces 12a and 12b.
[0027] Here, the guide pieces 12a and 12b are formed in circular
shapes so that the guide parts 42 of the first and second wheels
40a and 40b are prevented from being escaped to the outside.
[0028] Band engaging holes 15a and 15b are formed on the upper
sides of the first and second side plates 10a and 10b foe engaging
with the band 30, so that the band 30 is engaged to the band
engaging holes 15a and 15b for thereby tightening the user's
feet.
[0029] According to the present invention, the first and second
wheels frames 40a and 40b are formed and engaged with the wheels
41a and 41b. Guide part 42 corresponding to the guide pieces 12a
and 12b are formed at each side of the first and second wheels
frames 40a and 40b.
[0030] A receipt groove 43 is formed at an upper side of the guide
part 42, so that the fixing pins 44a and 44b are elastically
inserted along with the spring 45.
[0031] The guide parts 42 are inserted into the guide pieces 12a
and 12b, and the first and second wheel frames 40a and 40b are
rotatably engaged at the first and second side plates 10a and 10b
with the rivet 50a and washer 50b. The fixing pins 44a and 44b are
selectively inserted into the first and second fixing holes 13a,
13b, 14a and 14b depending on the positions of the first and second
wheel frames 40a and 40b.
[0032] The operation and effects of the roller skate according to
the present invention will be described.
[0033] When a user wears and uses the roller skate according to the
present invention, it is needed to adjust the width of the shoe
with the width of the roller skate. As the adjusting bolt 19 of the
male engaging part 11b is rotated, the adjusting nut 17 of the
female engaging part 11a thread-engaged with the adjusting bolt 19
is pulled or pushed, so that the female engaging part 11a fixed
with the adjusting nut 17 is pulled or pushed. So, the first side
plate 10a is pulled or pushed, so that the interval between the
first and second side plates 10a and 10b is adjusted for the width
of the shoe.
[0034] After the interval between the first and second side plates
10a and 10b is adjusted for the width of the shoe, when it is
needed to use the roller skate according to the present invention,
the fixing pins 44a and 44b are pushed toward the receipt groove 43
of the first and second wheel frames 40a and 40b, and the first and
second wheel frames 40a and 40b are rotated downward, and the guide
parts 42a of the first and second wheel frames 40a and 40b are
rotated along the guide plates 12a and 12b of the first and second
side plates 10a and 10b. When they come to the second fixing holes
14a and 14b of the guide pieces 12a and 12b, the fixing pins 44a
and 44b lose the recovery force of the spring 45, and are fixedly
inserted into the second fixing holes 14a and 14b, and the wheels
41a and 41b of the first and second wheel frames 40a and 40b are
protruded to the lower side of the footrest 20 for thereby enjoying
the roller skate.
[0035] When the user wishes to stop the roller skate in the course
of operation, the fixing pins 44a and 44b inserted into the second
fixing holes 14a and 14b are pushed toward the receipt groove 43 of
the first and second wheel frames 40a and 40b, and the first and
second wheel frames 40a and 40b are rotated up, and the guide parts
42 of the first and second wheel frames 40a and 40b are rotated
along the guide pieces 12a and 12b of the first and second side
plates 10a and 10b. When they come to the positions of the first
fixing holes 13a and 13b of the guide pieces 12a and 12b, the
fixing pins 44a and 44b are fixedly inserted into the first fixing
holes 13a and 13b with the help of the recovery force of the spring
45, and the wheels 41a and 41b of the first and second wheel frames
40a and 40b rise to the upper side of the footrest 20. So, the user
can walk like wearing the actual shoes.
[0036] The user can enjoy the roller skate based on the up and down
movements of the first and second wheel frames 40a and 40b and can
walk like wearing the actual shoes. When the rear side of the
roller skate is rotated down in the course of the roller skate, the
foot rest 20 contacts with the ground for thereby obtaining a
braking operation for quick stop. So, it is possible to prevent a
safety accident.
[0037] As described above, since it is possible to freely adjust
the width, and it is detachably attached to the rear side of the
shoe, and the wheels are designed to rotate. When the roller skate
is used, the wheels are moved down, and when it is not used, the
wheels are moved up, so that it is possible to obtain a walking
procedure like wearing the actual shoes while enjoying the roller
skate. The storing and wearing are easy, and it is possible to
adjust the sizes depending on the shoes. It is easy to practice
start, running and stop. Since the wheels are provided at only the
rear side of the shoe, anyone can enjoy the present invention
irrespective of sex and age. It is possible to prevent safety
accident in the present invention.
[0038] As the present invention may be embodied in several forms
without departing from the spirit or essential characteristics
thereof, it should also be understood that the above-described
examples are not limited by any of the details of the foregoing
description, unless otherwise specified, but rather should be
construed broadly within its spirit and scope as defined in the
appended claims, and therefore all changes and modifications that
fall within the meets and bounds of the claims, or equivalences of
such meets and bounds are therefore intended to be embraced by the
appended claims.
