Roller skate with a micro adjustment device
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.
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 INVENTIONThere 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.
In view of these and many other shortcomings, the inventor has invented the present invention to do a micro adjustment.
SUMMARY OF THE INVENTIONIt 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.
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.
It is a further object of the present invention to provide a roller skate with a micro adjustment, which is inexpensive in manufacture.
BRIEF DESCRIPTION OF THE DRAWINGS
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.
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.
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.
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
