Accordingly, the shoes are detachable from the skating devices so that it's convenient to assemble, stable and safe to use.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a detachable skate, and more particularly to a skate whose shoe can be detached from the skating device for walking.




2. Description of the Prior Art




The shoe and the skating device of conventional roller skates, ice skates and in-line skates are all integrated in a body so that they have a large volume and are not easy to carry. Moreover, they are useless except the skating exercise. When either the shoe or the skating device is defective or malfunctioning, the whole body becomes a discard. Furthermore, their defective or malfunctioning parts is not repairable. This is another drawback of the conventional skates. In order to improve the conventional skates in an integrated form, Taiwan Pat. No. 447319 “detachable in-line skate” discloses a detachable structure of the shoe and the skating device (see FIGS.


11


through


13


). In this disclosure, the shoe


11


is connected only with the front end of the skating device


12


by a safety pin


10


while the rear end of thereof has no safety arrangement. Thus, the fixing force between the shoe


11


and the skating device


12


only by means of a safety pin


10


is insufficient and it only focuses at the front side. Consequently, both parts of this in-line skate are easily taken apart.




In addition, another Taiwan Pat. Nos. 338338, 182154 and 205169 also teach a detachable design of the shoe and the skating device, having their own features. However, they still have drawbacks for improvement. Their technologies are much different from the present invention so that no further descriptions are given hereinafter.




SUMMARY OF THE INVENTION




It is a primary object of the present invention to provide a detachable skate having two sets of engagement members containing two female members and two male members which are correspondingly fitted to a sole at the bottom of the shoe and a mounting plate at the top of the skating device. In addition, the shoes are detachable from the skating devices so that it's convenient to assemble, stable and safe to use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




First of all, referring to

FIGS. 1 through 5

, the present invention primarily includes a shoe


20


and a skating device


30


.




Two sets of engagement members consist of two female members


22




a,




22




b


and two male members


32




a,




32




b


correspondingly fitted to a sole


21


at the bottom of the shoe


20


and a mounting plate


31


at the top of the skating device


30


.




The female members


22




a,




22




b


are constructed as a socket with an opening downward. At least one projecting pin


221


is radially mounted on the internal wall of each of the female members


22




a,




22




b.


Besides, a vertical guide post


222


is disposed in the middle of the female members


22




a,




22




b.






The male members


32




a,




32




b


can be fitted into the female members


22




a,




22




b.


An L-shaped guide slot


321


corresponding to the projecting pin


221


is formed at the outer side of the male members


32




a,




32




b.


In addition, the male member


32




b


is provided with a lever


33


through which the male member


32




b


can be turned on the guide post


222


at a certain angle. Moreover, the male members


32




a,




32




b


have a guide hole


322


in the middle thereof corresponding to the guide post


222


of the female members


22




a,




22




b.






Therefore, the female members


22




a,




22




b


and the male members


32




a,




32




b


can be connected with each other by means of the engagement of the projecting pin


221


into the bottom end of the vertical part of the L-shaped guide slot


321


, whereupon the projecting pin


221


is turned to the front end of the horizontal part thereof. Accordingly, the female members


22




a,




22




b


and the male members


32




a,




32




b


are secured to each other while the shoe


20


and the skating device


30


are stably fixed together.




The guide post


222


of the female members


22




a,




22




b


and the guide hole


322


of the male members


32




a,




32




b


are used for alignment in place during in the engagement operation.




An applicable embodiment of the mounting way of the male members


32




b


is illustrated in FIG.


3


. The mounting plate


31


is provided with a round through hole


311


from which the male members


32




b


is able to project upwards. The lever


33


is fitted to a groove


312


at the bottom of the mounting plate


31


so that the lever


33


is rotatable to certain extent. Besides, a fixing plate


34


is fitted to the bottom of the mounting plate


31


for sealing the bottom of the groove


312


. Accordingly, the male member


32




b


is pivotably connected to the mounting plate


31


.




In order to fix the lever


33


in place, the lever


33


is provided with a resilient element


331


to keep the male members


32




b


in a locked state. The resilient element


331


can be a compression spring or a leaf spring. It's aimed that the male member


32




b


doesn't move during exercise. It's found from the experiments that the male member


32




b


won't be loosened when the female member


22




b


and the male member


32




b


are secured together only if the projecting pin


221


and the L-shaped guide slot


321


are correctly engaged. So, the safety can be certainly enhanced with the resilient element


331


.




Base upon the above, the assembly of the present invention, as shown in FIGS.


4


and


7


, is performed in the way that the sole


21


of the shoe


20


is located at an angle of about 30° to the mounting plate


31


of the skating device


30


. Thereafter, the female member


22




a


is correspondingly connected the male member


32




a


and is turned inwards at an angle in order that the projecting pin


221


is engaged into the horizontal part of the L-shaped guide slot


321


. At this time, the sole


21


is pivoted on the female member


22




a


and the male member


32




a.


As illustrated by the arrow P


1


, the sole


21


is moved toward the top of the mounting plate


31


while the lever


33


is moved outwards in the direction shown by the arrow P


2


so that the projecting pin


221


of the female member


22




b


can be aligned with the vertical opening of the L-shaped guide slot


321


of the male member


32




b


for inserting thereinto. Soon after that, the lever


33


is turned inwards to bring the male member


32




b


back to the position shown in FIG.


8


. Now, both projecting pins


221


of the female members


22




a,




22




b


are engaged into the horizontal part of the L-shaped guide slots


321


of the male members


32




a,




32




b.


Thus, the present invention utilizes a turning angle and L-shaped engagement to ensure a stable connection between the shoe


20


and the skating device


30


during the exercise session so that it can be safely used.




Accordingly, the female members


22




a,




22




b


and the male members


32




a,




32




b


can be connected by means of the engagement of the projecting pins


221


into the L-shaped guide slots


321


so that the shoe


20


and the skating device


30


are secured together through a simple engagement operation. In addition to the roller skates, the present invention can also be applicable to the ice skates


30




a


and the in-line skates


30




b


whose shoes


20


are detachable from the skating devices so that it's convenient to assemble, stable and safe to use.




Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
