BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] 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
[0002] 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
[0003] 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.
[0004] 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
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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
[0011] 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.
[0012] 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.
