Skate Having A Size Adjustable Function

Abstract

A skate includes a lower base, an upper base adjustably mounted on the lower base, and a control knob mounted on the lower base and detachably locked onto the upper base. The upper base has a slide provided with a plurality of locking teeth. The control knob is movably mounted in the lower base and has a first end provided with a support and a second end provided with a press button protruding from the lower base. The support of the control knob has a locking groove detachably locked on one of the locking teeth of the upper base.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a skate and, more particularly, to a skate, such as an in-line skate, a roller skate and the like.[0003]2. Description of the Related Art[0004]A conventional skate in accordance with the prior art shown in FIGS. 6-10 comprises a lower base 50, an upper base 60 adjustably mounted on the lower base 50, and a control knob 70 mounted on the lower base 50 and detachably locked onto the upper base 60 to releasably lock the upper base 60 onto the lower base 50. The lower base 50 has a top provided with a slideway 52 and a receiving channel 53 connected to the slideway 52. The receiving channel 53 of the lower base 50 is perpendicular to the slideway 52 of the lower base 50. The top of the lower base 50 has a periphery provided with a protruding limit block 51. The upper base 60 has a bottom provided with a slide 62 slidably mounted in the slideway 52 of the lower base 50. The slide 62 of the up...

Benefits of technology

[0009]Another objective of the present invention is to provide a skate, wherein the respective one of the locking teeth of the upper base is supported between the two opposite sidewalls of the locking groove to increase the contact area between the respective one of the locking teeth of the upper base and the support of the control knob so as to increase the combination strength of the control knob and the slide of the upper base so that the support of the control knob is combined with the locking teeth of the upper base solidly and exactly.

[0010]A further objective of the present invention is to provide a skate, wherein the slide of the upper base is integrally formed with the locking teeth, and the support of the control knob is integrally formed with the locking groove, so that each of the locking teeth of the upper base has a greater strength to withstand a larger shear stress and is not worn out or broken easily during a long-term utilization, thereby greatly enhancing the lifetime of the skate.

Problems solved by technology

However, the control knob 70 is not integrally formed with the positioning rod 71 so that the positioning rod 71 has a smaller strength and cannot withstand a larger shear stress.

Thus, the positioning rod 71 is worn out or broken easily during a long-term utilization, thereby greatly decreasing the lifetime of the skate.
