Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to the roller skate that is easy to
attach and detach. In more detail, this invention shall pertain to
the roller skate that can be attached and detached from the shoes
regardless of feet size by enabling width to be adjusted in
discretion if and when necessary, and this invention shall be
comprised of two wheels.
[0003] 2. Description of the Prior Art
[0004] Regular roller skate shall be comprised of structure that is
comprised of four rollers that rotate while slipping to the floor
and which is fixed and attached onto the bottom of the roller skate
in two parts in a stable manner or structure that is fixed and
attached with numerous rollers in a row in order to enhance speed
or sense of balance.
[0005] Likewise, hitherto roller skate enables user to enjoy riding
it when the user rides fast by rolling the feet powerfully while
balancing the body after tying the roller skate tight while
worn.
[0006] Hitherto regular roller skate requires roller skate that
fits feet size since user cannot enjoy riding it when the feet size
does not fit the roller skate since numerous rollers are fixed and
attached onto the roller skate that is produced in different
sizes.
[0007] It is not possible to wear roller skate if and when the feet
size does not fit the size of the feet. Moreover, if and when the
roller skate with large size is worn, there is risk of getting
blisters or pain on the feet and safety related accidents. Thus, in
the case of children who grow fast every day, they cannot use the
roller skate that they purchased for a prolonged period of time
since it does not fit the feet size.
[0008] In addition, hitherto roller skate is difficult to carry due
to its large bulk since it is structured by the fixation and
attachment of numerous rollers and roller skate. Meanwhile, roller
is worn or torn, financial problems such as the need to find repair
shop or to purchase new roller skate incur.
[0009] Moreover, user needs to change into user's shoes when the
user finishes using roller skate. Roller skate that is taken off
shall be stored or carried. In the above mentioned case, shoes are
not easy to store or carry due to the bulk of the shoes that is
formed as single unit.
SUMMARY OF THE INVENTION
[0010] This invention relates to the roller skate that is easy to
attach and detach that can attach and detach from the shoes
regardless of feet size by enabling width to be adjusted in
discretion if and when necessary, and this invention shall be
comprised of two wheels.
[0011] This invention shall comprise projection sill towards the
direction of width when it pertains to the foothold of the other
side where the side wall is formed. Center shall be comprised of
conjoining part that is formed with numerous conjoining holes.
Foothold of other surface shall form -shaped groove towards the
direction of width so that the above mentioned projection sill can
be fit in. Conjoining hole shall be formed at the center, and
conjoining part shall be comprised so that the above mentioned
conjoining part can be fit into the lower part. Wheel protection
support shall be formed on the above mentioned side wall in single
unit. Wheel shall be formed between the side wall and wheel
protection support so that it can rotate. At the upper part of the
side wall, band and clip shall be comprised so that it shall be
detached and attached at the rear part of the shoes. However,
conjoining sill and -shaped groove, and conjoining part and
conjoining part of the above mentioned foothold shall be mutually
