Abstract
The present invention relates to a size-adjusting fastening mechanism for stakes comprising fixed locking grooves and a movable locking convex block, whereby when one of the grooves engages with the convex block, tooth position is loosened and toecap is telescopic upon pulling. When the groove and the convex block are rotated to deflect so as not to engage with each other, tooth position is pressed to lock so as to be irremovable. Such a structure requires that the pull handle be pulled horizontally forwards and backwards. Being secured with rivet punching, the claimed device possesses good stability, is simple in structure, low in cost and easy for operation.
Claims4
A size-adjusting fastening mechanism applicable for single-roller and double-roller skates and ice stakes, comprising fastening bolts or rivets going through a shoe body and a toecap, fixed fastening blocks fixedly connected to the shoe body, and movable fastening blocks fixedly connected to the fastening bolts or rivets,
- wherein the fixed fastening blocks have grooves, and wherein the grooves include locking grooves and unlocking grooves perpendicularly arranged with regard to each other, and that there is a difference in height between the bottom surface of the locking grooves and the bottom surface of the unlocking grooves, which difference in height is greater than a summation of tooth heights of positioning buckle teeth of the shoe body and the toecap.
