Abstract
A combined skateboard and ski which includes a body board having two bottom riser pads, a ski, and cushions. Lock nuts and two mounting frames are provided on a top side of the ski for securing the ski to the riser pads of the body board. Each of the mounting frames has a support arm and a pivot hole formed in the support arm. Two wheel assemblies are fastened to the riser pads of the body board by cushions and lock nuts to form a skateboard after removal of the mounting frames from the riser pads.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a skateboard and ski arrangement, which enables a skateboard to be detachably fastened to a ski for sliding over snow.
2. Description of the Related Art
A regular ski, as shown in

, and two mounting structures
5
that connect the footplate
4
to the skiing board
3
. Each mounting structure
5
comprises a first mounting frame
51
fixedly provided at the bottom side of the footplate
4
, a second mounting frame
52
fixedly provided at the top side of the skiing board

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. from
1
through
5
, a ski
1
is showing having two mounting frames
11
(only one pivot holder is shown in the drawings). Each mounting frame
11
comprises an angled support arm
111
vertically extended upwards and then turned sideways in horizontal direction, a pivot hole
112
in the horizontal upper part of the support arm
111
, and a locating rod
114
extended from the horizontal upper part of the support arm
111
. The skateboard, referenced by
2
, comprises a board body
23
, two riser pads
21
fixedly provided at the bottom side of the board body
23
(only one riser pad is shown in the drawings). Each riser pad
21
comprises a locating hole
211
and a threaded pivot
213
for the mounting of one mounting frame
11
of the ski
1
or a wheel assembly
22
selectively. The wheel assembly
22
comprises a wheel holder
221
holding two wheels
224
at two sides, a pivot hole
222
in the wheel holder
221
between the wheels
224
, and a locating rod
223
extended from a middle part of the wheel holder
221
.
The mounting frame
11
can be fastened to the corresponding riser pad
21
of the board body
23
by: inserting the threaded pivot
213
of the riser pad
21
through the pivot hole
112
and the locating rod
114
into the locating hole
211
, and then threading a lock nut
215
onto the threaded pivot
213
to fix the threaded pivot
213
to the mounting frame
11
. Further, cushions
214
are respectively mounted on the threaded pivot
213
and secured between the riser
21
and the lock nut
215
at two sides of the support arm
111
of the mounting frame
11
. Because the horizontal upper part of the support arm
111
is suspended above the base of the mounting frame
11
by a gap
113
, the user can conveniently insert a wrench into the gap
113
to fasten up or loose the lock nut
215
. The connection of the wheel assembly
22
to the riser pad
21
is also easy. By inserting the threaded pivot
213
through the cushions
214
and the pivot hole
222
and the locating rod
223
into the locating hole
211
and then fastening the lock nut
215
to the threaded pivot
213
, the wheel assembly
22
is fastened to the riser pad
21
.
The user can selectively fasten two wheel assemblies
22
or the mounting frames
11
of the ski
1
to the riser pads
21
of the board body
23
. When two wheel assemblies
22
fastened to the riser pads
21
of the board body
23
, the board body
23
and the wheel assemblies
22
form a skateboard for skating. When the mounting frames
11
of the ski
1
fastened to the riser pads
21
of the board body
23
, the user can stand on the board body
23
to slide over snow.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
