Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a replaceable skate assembly, and more particularly to a replaceable skate assembly, wherein the base may be assembled on and detached from the bottom of the boot quickly, easily and conveniently, thereby facilitating the user using the replaceable skate assembly.




2. Description of the Related Art




A conventional replaceable skate assembly


5


in accordance with the prior art shown in

FIG. 6

comprises a boot


51


, and a base


52


mounted on the bottom of the boot


51


. The bottom of the boot


51


is provided with an aluminum alloy structure which is formed with two recesses


511


each protruded with an insertion tenon


512


which has a side face formed with an insertion hole


513


. The base


52


is provided with two mounting seats


521


each mounted in one of the two recesses


511


of the boot


51


. Each of the two mounting seats


521


is provided with a receiving chamber


522


for receiving the insertion tenon


512


. The receiving chamber


522


has a side face formed with a through hole


5220


aligning with the insertion hole


513


of the insertion tenon


512


. Each of the two mounting seats


521


is also provided with a catch plate


523


formed with a through hole


5230


. Each of the two mounting seats


521


is also provided with a safety pin


524


, a spring


525


and a bent bar


526


mounted between the receiving chamber


522


and the catch plate


523


.




In operation, the user may operate the bent bar


526


to move the safety pin


524


, so that the safety pin


524


may be inserted into and detached from the insertion hole


513


of the insertion tenon


512


of the boot


51


by the elastic action of the spring


525


. Thus, the base


52


may be mounted on or detached from the bottom of the boot


51


according to the user's requirements.




However, when the base


52


is mounted on the bottom of the boot


51


, the safety pin


524


cannot align with the insertion hole


513


of the insertion tenon


512


of the boot


51


easily, so that the base


52


cannot be mounted on the bottom of the boot


51


easily and conveniently. In addition, it is necessary to additionally provide an aluminum alloy structure on the bottom of the boot


51


, thereby complicating the procedure of fabrication, and thereby increasing the cost of fabrication.

222


of the mounting block


221


of the second mounting seat


22


of the base


20


is located between the first positioning plate


23


and the second positioning plate


24


of the second mounting seat


22


of the base


20


.




The second end of the base


20


is formed with a circular hole


25


aligning with the through hole

of the second positioning plate


24


of the second mounting seat


22


of the base


20


. The second mounting seat


22


of the base


20


has a first side formed with a through hole


26


for passage of a bolt


28


and a screw


281


, and a second side formed with a through hole


27


for passage of a bolt


29


and a screw


291


.




The locking device


30


is mounted between the first positioning plate


23


and the second positioning plate


24


of the second mounting seat


22


of the base


20


, and includes a positioning rod


31


, a C-shaped snap ring


32


, an inverted L-shaped locking pawl


33


, a spring


34


, and a screw


35


. The positioning rod


31


has a first end formed with an annular groove


311


and a second end formed with a screw bore


312


. The locking pawl


33


has a top end provided with a wedge-shaped catch block


331


extended outward, and has a lower portion formed with a through hole


332


. The spring


34


is mounted on the positioning rod


31


, and is urged between the first positioning plate


23


and the second positioning plate


24


of the second mounting seat


22


of the base


20


.




In assembly, the locking pawl


33


is extended through the through hole


224


into the receiving space


222


of the mounting block


221


of the second mounting seat


22


of the base


20


, with the wedge-shaped catch block


331


of the locking pawl


33


being received in and protruded outward from the square hole


223


of the receiving space


222


of the mounting block


221


of the second mounting seat


22


of the base


20


. Then, the positioning rod


31


is in turn extended through the through hole


231


of the first positioning plate


23


of the second mounting seat


22


of the base


20


, the through hole


332


of the locking pawl


33


, the spring


34


, the through hole


241


of the second positioning plate


24


of the second mounting seat


22


of the base


20


and the circular hole


25


of the base


20


, and is protruded outward from the circular hole


25


of the base


20


. Then, the screw


35


is screwed into the screw bore


312


of the positioning rod


31


. Then, the C-shaped snap ring


32


is secured in the annular groove


311


of the positioning rod


31


, and is located between the locking pawl


33


and the first positioning plate


23


of the second mounting seat


22


of the base


20


, thereby accomplishing assembly of the locking device


30


.




By such a design, the locking device


30


may co-operate with the mounting block


221


of the second mounting seat


22


of the base


20


to form a locking fit with the locking cavity


121


of the connecting recess


12


of the boot


10


.




In operation, referring to

FIGS. 2-4

with reference to

FIG. 1

, the locking block


211


of the first mounting seat


21


of the base


20


may be locked in the locking recess


11


of the boot


10


, while the mounting block


221


of the second mounting seat


22


of the base


20


may be received in the connecting recess


12


of the boot


10


. At this time, by the design of the inclined surface of the wedge-shaped catch block


331


of the locking pawl


33


and by the elasticity of the spring


34


, the wedge-shaped catch block


331


of the locking pawl


33


may be forced into the locking cavity


121


of the connecting recess


12


of the boot


10


, thereby locking the mounting block


221


of the second mounting seat


22


of the base


20


in the connecting recess


12


of the boot


10


, so that the base


20


may be mounted and fixed on the bottom of the boot


10


as shown in FIG.


4


.




On the contrary, the user may push the positioning rod


31


or pull the screw


35


to move the locking pawl


33


which may be moved from the position as shown in

FIG. 2

to the position as shown in

FIG. 3

, thereby detaching the wedge-shaped catch block


331


of the locking pawl


33


from the locking cavity


121


of the connecting recess


12


of the boot


10


, so that the base


20


may be detached from the bottom of the boot


10


. Then, the locking pawl


33


may be returned to the original position by the restoring force of the spring


34


.




Referring to

FIG. 5

with reference to

FIG. 1

, the replaceable skate assembly


1


in accordance with another embodiment of the present invention further comprises an ankle guard


4


that may be mounted on the second mounting seat


22


of the base


20


by the through hole


26


for passage of the bolt


28


and the screw


281


, and the through hole


27


for passage of the bolt


29


and the screw


291


, so that the ankle guard


4


may be locked on the second mounting seat


22


of the base


20


.




Accordingly, the replaceable skate assembly


1


in accordance with the present invention has the following advantages.




1. The base


20


may be assembled on and detached from the bottom of the boot


10


quickly, easily and conveniently, thereby facilitating the user using the replaceable skate assembly


1


.




2. The bottom of the boot


10


is integrally formed with the boot


10


, without having to additionally provide an aluminum alloy structure on the bottom of the boot


10


, thereby simplifying the procedure of fabrication, and thereby decreasing the cost of fabrication.




Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
