Abstract

Ice-skates changeable to common sneakers includes a sneaker body (1) and a lower functional unit (2) (such as an ice-skate unit, a roller skate unit, etc.), assembled with or disassembled from each other. The sneaker body (1) has a sole (10) and a large sole (11) under the sole, and the sole (10) has plural recesses (100) and a tenon (101) formed in each recess, and one of the tenons has an insert sole (102) in its sidewall. The lower functional unit (2) has plural connect members (20) with mortises (200) engaging the tenons (101). Each connect member (20) has a stop plate (203) in front of the mortise, with an aperture (202) formed between them for a safety pin (22) and a spring (21) fitted around the pin to fit therein. The safety pin passes through the hole (204) of the stop plate (203) and a lateral hole (201) of the inner wall of the mortise (200), with its outer end inserting in the insert hole of the tenon (101). A curved rod (23) is combined with the safety rod, forcing the safety pin (22) move back and forth to permit the sneaker body assembled with or disassembled from the lower function unit to become ice-skates, roller-skates etc..

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a pair of ice-skates changeable to a pair of common sneakers, particularly to one having a sneaker body and an ice skating unit combinable with or separable from the sneaker body to be used for two objects.

2. Description of the Prior Art

Sneakers have a wide variety for different designs and uses, such as for basketball, jogging, mountaineering, and special sports (such as ice-skating, roller-skating in-line skating, etc.). Special sports shoes have special and different functions for special sports, impossible to be widely used as common sneakers, limited in usable time and places.

SUMMARY OF THE INVENTION

The objective of the invention is to offer ice-skates changeable to common sneakers for walking or jogging having an ice skating unit combinable with or separable from the sneaker body.
The feature of the invention is the sneaker body having plural recesses formed in a sole and a large sole under the sole, a tenon formed in each recess, an insert hole formed in one side of one tenon, and an ice skating unit combined with the sole of the sneaker body and having plural connect members respectively having a mortise and fitting in the recesses of the sole, with the each mortise engaging with the tenon in each recess of the sole, and a safety pin and a coil spring fitting around the safety pin fitted in an aperture defined between a stop plate and an inner wall of each mortise and passing a center hole of the stop plate and a lateral hole in the inner wall of the mortise and in the insert hole of a side wall of the tenon. A curved rod is combined with an inner end of the safety pin, pressed or released to move the safety pin back and forth to assemble or disassemble the sneaker body with or from the lower functional unit to form an ice skate or a roller skate or an in-line skate.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of ice-skates changeable to common sneakers in the present invention, as shown in Fig. 1 and 2, includes a sneaker body 1, and a lower functional unit 2 (an in-line skate unit illustrated in Figures, but, an ice skate unit or a roller-skate unit also possible to be used) combined together separably.
The sneaker body 1 includes a sole 10 and a large separate sole 11 under the sole 10, and the sole 10 has plural recesses 100 spaced apart properly. Each recess 100 has a tenon 101, and one of the tenons 101 has a sidewise insert hole 102 in a sidewall. Further, a circumferential projecting edge 103 is formed around each recess 100. The large separate sole 11 surrounds and adheres with the sole 10, having through holes 110 aligned to the recesses 100 and the circumferential projecting edges 103 just fit tightly in an inner wall of each through hole 110, as shown in Fig. 2.
The lower functional unit 2 may be assembled with or disassembled from the sneaker body 1, having an exclusive function for in-line skating but for other units such as an ice skate unit, or a roller skate unit also may be used. The lower functional unit 2 has plural connect members 20 formed on a rear portion and on a front portion of an upper surface and provided with mortises 200 to engage with the tenon 101 of each recess 100.
Further the mortise 200 of each connect member 20 has a lateral hole 201 in an inner wall defining each mortise 200, and a stop plate 203 vertically provided in front of each mortise 200 on each connect member 20 and having a center hole 204 in line to the lateral hole 201. An aperture 202 is formed between the inner wall of each mortise 200 and each stop plate 203 for receiving a safety pin 22 and a coil spring 21 fitting around the safety pin 22 therein. Further, the safety pin 22 passes through the center hole 204 of the stop plate 203, the coil spring 21 and the lateral hole 201 of the mortise 200, having its front end inserting in the sidewise insert hole 102 of the tenon 102 of the sole 10, and an intermediate portion fitted around with a stop ring 220 to rest against the outer wall of the lateral hole 201 of the mortise 200. Further, a curved-down rod 220 is provided to have its rear end connected firmly to the inner end of the safety pin 22, an intermediate point resting against an inner end side of the connect member 20, and a free end 230 a little curved outward. Thus each curved rod 23 can pull back and forth each safety pin 22 by means of the intermediate point as a fulcrum, and the coil spring 21 can force the safety pin 22 to move automatically back to its original position with its resilience, as shown in Figs. 2 and 3.
In assembling and using, referring to Figs. 1, 2, 3 and 4, the large sole 11 is positioned to surround the sole 10 and adhered together, with the through holes 111 respectively aligned to the relative recesses 100 and the circumferential edges 103, finishing assembly of the sneaker body 1. Next, the assembled sneaker body 1 is to be assembled with the lower functional unit 2, align and insert the tenons 101 in the mortises 200 of the connect members 20 of the lower functional unit 2, and press the end 230 of the curved rod 23 to force the stop ring 220 of the safety pin 22 compress the coil spring 21 to force the front end of the safety pin 22 insert in the insert hole 102 of the tenon 101 and stabilized therein, as shown in Fig. 2. Then the sneaker body 1 is assembled with the lower roller-skating unit 2 stably, usable as the in-line skates as shown in Fig. 4
The invention has the following advantages, as understood from the aforesaid description.
1. It has a few components, quick and convenient to assemble and disassemble.
2. It can be used as common leisure sneakers.
3. It has two kinds of uses, saving expenditure and storing space.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
