DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to Figs. 1 and 2, a replaceable skate assembly 1 in accordance with a preferred embodiment of the present invention comprises a boot 10, a base 20 mounted on the bottom ofthe boot 10, and a locking device 30 mounted in the base 20.
The bottom of the boot 10 is integrally formed with the boot 10. The bottom of the boot 10 has a first end formed with a locking recess 11 and a second end formed with a connecting recess 12. The connecting recess 12 of the boot 10 has a side formed with a locking cavity 121.
The base 20 is available for a skate, such as an ice skate, a roller skate, an in-line roller skate or the like. The base 20 may be directly mounted on the bottom of the boot 10. The base 20 has a first end provided with a first to mounting seat 21 and a second end provided with a second mounting seat 22.
The first mounting seat 21 of the base 20 has a top provided with a locking block 211 that may be locked in the locking recess 11 of the boot 10.
The second mounting seat 22 of the base 20 has a top provided with a mounting block 221 that may be received in the connecting recess 12 of the boot 10. The mounting block 221 of the second mounting seat 22 of the base 20 has an inside formed with a closed receiving space 222 which has a side formed with a square hole 223 and a bottom formed with a through hole 224.
The second mounting seat 22 of the base 20 has a bottom provided with a first positioning plate 23 formed with a through hole 231 and a second positioning 2o plate 24 formed with a through hole 241. The through hole 224 of the receiving space 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.
s The second end of the base 20 is formed with a circular hole 25 aligning with the through hole 241 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 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 l0 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 tum 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 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 t o 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 21 I 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 2o 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 and 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.
s 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.
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 s chamber 522 and the catch plate 523.
In operation, the user may operate the bent bar S26 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.
