Roller skate with a micro adjustment device
Abstract
A roller skate with a micro adjustment device includes a wheel
frame, a quarter and a vamp. Two side boards of the wheel frame
have a first chain and a slot. Two side boards of the vamp has a
third chain and a guiding hole. The top end of the wheel frame is
formed with a second chain. A quick release device is inserted with
its shaft through the guiding hole of the vamp and the slot of the
wheel frame, the first chain corresponding to the third chain. The
shaft has a gear corresponding to the second chain. By tightening
and loosening of the quick release device, the gear is adjustable
with respect to the second chain, thus the third chain of the vamp
is adjustable along the first chain of the wheel frame.

Description
FIELD OF THE INVENTION
[0001] This invention relates to a roller skate with a micro
adjustment device adapted to the traditional four-wheels roller
skate, inline skate, tri-wheels roller skate, and ice skate.
BACKGROUND OF THE INVENTION
[0002] There are various models of roller skates on the market.
Each skate has a size to fit a user with the size of feet. However,
when the user grows up, the size will not fit anymore, and the
skate has to be replaced, which is not cost effectiveness. An
adjustable skater is disclosed later on, which comprises a front
and a rear sections, by adjusting one of the sections, the skater's
size may be changed to fit users with different sizes of feet.
These skaters may have a heavy weight, which will hurt the user's
ankles. Further the adjustment is a large scale, therefore, in many
times the adjusting size is either slightly large or small.
[0003] In view of these and many other shortcomings, the inventor
has invented the present invention to do a micro adjustment.
SUMMARY OF THE INVENTION
[0004] It is the primary object of the present invention to provide
a roller skate with a micro adjustment device, which uses a micro
adjustment to reach the most desirable size for a user, so as to
minimize the burden from wearing the skate and to prevent any
possible damages.
[0005] It is another object of the present invention to provide a
roller skate with a micro adjustment device, which uses few
components, therefore has less weight and burden to a user.
[0006] It is a further object of the present invention to provide a
roller skate with a micro adjustment, which is inexpensive in
manufacture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] A roller skate with a micro adjustment device of the present
invention is generally composed of a wheel frame 1, a quarter 2,
and a vamp 3.
[0014] The wheel frame 1 is identical to a conventional skate,
which comprises a block 17 on the front top end with two rails 171
along two sides thereof, a pair of side boards extending from two
sides from the top end downwardly and secured with wheels 16,
respectively. The outer sides of the side boards are formed with a
first chain 12 which comprises a slot 11 thereat. The top end of
the wheel frame 1 comprises a second chain 13. Two front locating
holes 14 and a rear locating hole 15 are formed on the top end of
the wheel frame 1, respectively.
[0015] The quarter 2 is secured to the top rear section of the
wheel frame 1, having a pair of front holes 21 and a rear hole 22
at the bottom thereof.
[0016] The vamp 3 is secured on the top front section of the wheel
frame 1, with two sides extending downward to form a pair of side
boards 31, respectively, and a third chain 33 on the inner wall of
the side boards 33 corresponding to the first chain 12 and having a
guiding hole 32 thereat corresponding to the slot 11. The vamp 3
has a sliding slot 38 at the front bottom end. The sliding slot 38
comprises a pair of ridges 381 at two sides corresponding to the
rails 171 of the block 17. A quick release device 34 is adapted to
connect the vamp 3 and the quarter 2. The quick release device 34,
as shown in FIG. 2, is secured to a disc 361 of a shaft 36 by a pin
35. The shaft 36 comprises a gear 37 at the center portion adapted
to mesh with the second chain 13. The shaft 36 has a pair of lugs
362 at the center so as to clamp into a trough 371 within the gear
37 and extending through the gear 37. The exposed end of the shaft
36 is secured by a pin C2 and a sleeve C thereat.
[0017] A second embodiment of the quick release device 34A, as
shown in FIG. 2A, is secured to a disc 361A of a shaft 36A by a pin
35A. The shaft 36A comprises a gear 37A at the center portion
adapted to mesh with the second chain 13. The shaft 36A is a round
stick with a cut-off section 363 at the center so as to clamp into
a trough 371A within the gear 37A and extending through the gear
37A. The exposed end of the shaft 36A is secured by the pin C2 and
a sleeve D thereat.
[0018] To assemble the present invention, as shown in FIGS. 3 and
4, a bolt A sleeved with a washer A1 is inserted through the rear
hole 22 of the quarter 2 and the rear locating hole 15 of the wheel
frame 1 and secured by a nut A2 from the other side thereof. Two
rivets B are inserted through the front holes 21 of the quarter 2,
the sliding slot 38 of the vamp 3, and the front locating holes 14
of the wheel frame 1 and riveted with washers B1 from the other end
thereof. The sliding slot 38 has the ridges 381 at respective sides
corresponding to the rails 171 of the block 17. This brings the
first chain 12 of the wheel frame 1 and the third chain 33 of the
vamp 3 to mesh together, as shown in FIG. 5. The gear 37 is located
between the two side boards of the wheel frame 1. The shaft 36 of
the quick release device 34 is inserted through a washer C1, the
guiding hole 32 of the vamp 3 and the slot 11 of the wheel frame 1,
with the lugs 362 inserted in the trough 371 of the gear 37 in a
secure manner, and is then coupled with the sleeve C and the pin
C2, preventing from loosening or dismantling from the guiding hole
32 of the vamp 3 and the slot 11 of the wheel frame 1, and urging
the gear 37 of the shaft 36 to mesh with the second chain 13 of the
wheel frame 1. Thus the wheel frame 1, the quarter 2, and the vamp
3 are secured together.
[0019] When in use, as shown in FIG. 5, the quick release device 34
is loosened to release the meshing status of the first chain 12 of
the wheel frame 1 from the third chain 33 of the vamp 3. Thus the
vamp 3 is able to move with respect to the wheel frame 1. By
spinning the shaft 36 of the quick release device 34, the shaft 36
links the gear 37 on the lugs 362 to spin. Because the gear 37
meshes with the second chain 13, the gear 37 is also linked to
slide along the second chain 13 simultaneously. This allows the
shaft 36 is linked to slide within the slot 11 of the wheel frame 1
while the ridges 381 of the sliding slot 38 of the vamp 3 slides
along the rails 171 of the block 17. The vamp 3 is allowed to slide
freely. When the vamp 3 reaches to a prompt distance, as shown in
FIG. 5, the quick release device 34 is fastened to force the third
chain 33 of the vamp 3 and the first chain 12 of the wheel framer 1
in a tight status to prevent from relative movement. Due to the
sizes of the teeth distance of the first chain 12, the third chain
33 and the gear 37 are relative close. The spinning requires little
adjustment and a micro adjustment can reach to different size,
precisely.
