main board 3, a fixing plate 4, a brake plate 5, and a support
plate 6. The main board 3 is movable on the snow ground "S" and a
tail end of the main board 3 facing to the snow ground "S" is
raised with an angle. The fixing plate 4 is fixed on the tail end
of the main board 3 facing the snow ground "S" and the brake plate
5 is attached to the main board 3 by the fixing plate 4. The fixing
plate 4 has a surface facing the snow ground "S" and formed with a
first fixing recess 40 and a second fixing recess 41. The brake
plate 5 is partially fixed in the first fixing recess 40 of the
fixing plate 4 and partially extended outward from the main board 3
to face the snow ground "S". The brake plate 5 has a first surface
facing the snow ground "S" and formed with a shovel portion 50 that
is inserted into the snow ground "S" so as to provide a braking

and the brake plate 5, so that an included angle is defined between
the fixing plate 4 and the brake plate 5. In the preferred
embodiment of the present invention, the support plate 6 has one
end pivotally mounted on a second surface of the brake plate 5
facing the fixing plate 4 and the other end inserted into the
second fixing recess 41 of the fixing plate 4.
[0044] As shown in FIGS. 9-11, the fixing plate 4 has a top
provided with a plurality of fixing receptors 42, such as bolts or
snap rivets for fixing the fixing plate 4 to the main board 3. The
shovel portion 50 of the brake plate 5 is extended toward the snow
ground "S". In the preferred embodiment of the present invention,
the shovel portion 50 of the brake plate 5 is a protruding plate
having a face directed toward the travel direction of the main
board 1. The brake plate 5 has a portion formed with at least one
drain hole 51 located adjacent to the shovel portion 50 to drain
the snow shoveled by the shovel portion 50. The first surface of
the brake plate 5 is formed with a first guide face 510 enclosed
around and smoothly connected to the drain hole 51 to guide the
snow shoveled by the shovel portion 50 to pass through the drain
hole 51. The second surface of the brake plate 5 is formed with a
peripheral wall 53 enclosed around the drain hole 51. The
peripheral wall 53 of the brake plate 5 has an inside formed with a
second guide face 511 smoothly connected to the first guide face
510 to guide the snow shoveled by the shovel portion 50 to drain
outward from the peripheral wall 53.
[0045] As shown in FIG. 11, the first guide face 510 of the brake
plate 5 has two opposite sides each formed with a lug 54 that is
gradually reduced in the travel direction of the main board 3 to
form a conic face to guide the snow shoveled by the shovel portion
50 into the drain hole 51.
[0046] As shown in FIGS. 9-12, the second surface of the brake
plate 5 is formed with two opposite shaft holes 52 facing the
second fixing recess 41 of the fixing plate 4 for mounting the
support plate 6. The support plate 6 is pivotally mounted between
the two opposite shaft holes 52 of the brake plate 5 and has two
ends each provided with a shaft 60 pivotally mounted in one of the
two opposite shaft holes 52 of the brake plate 5. The second fixing
recess 41 of the fixing plate 4 has a side formed with a locking
groove 410, and the support plate 6 has a side provided with a
locking flange 61 detachably locked in the locking groove 410 of
the second fixing recess 41 of the fixing plate 4.
[0047] As shown in FIG. 12, the support plate 6 is pivotally
mounted between the two opposite shaft holes 52 of the brake plate
5 by the shafts 60, and the locking flange 61 of the support plate
6 is detachably locked in the locking groove 410 of the second
fixing recess 41 of the fixing plate 4, so that the support plate 6
is pivotally mounted on the brake plate 5 and is detachably locked
by the fixing plate 4.
[0048] As shown in FIG. 13, the brake plate 5 is made of resilient
and flexible material, such as PE having a lower density. Thus, the
locking flange 61 of the support plate 6 is pushed to detach from
the locking groove 410 of the second fixing recess 41 of the fixing
plate 4 to release the support plate 6 from the fixing plate 4, so
that the support plate 6 is pivoted relative to and rested on the
brake plate 5, thereby folding the brake plate 5 on the main board
3. Thus, the slider is portable and has a smaller folded volume,
thereby saving space of storage and transportation.
[0049] As shown in FIG. 14, when in use, the brake plate 5 is
pressed toward the snow ground "S", so that the shovel portion 50
of the brake plate 5 is inserted into the snow ground "S", thereby
forming a resistance so as to brake movement of the main board 3.
In practice, when the user is seated on the main board 3, the user
only needs to shift the center of gravity backward to press the
brake plate 5 so as to produce the braking effect, thereby
facilitating the user operating the brake plate 5 to brake the main
board 3. Alternatively, the user could also lean back his/her body
to have the brake plate 5 pressed so as to provide the braking
effect. Thus, the user can operate the brake plate 5 to brake the
main board 3 easily and conveniently. In addition, the snow
shoveled by the shovel portion 50 of the brake plate 5 is drained
outward from the drain hole 51 by provision of the first guide face
510, the second guide face 511, the peripheral wall 53 and the lug
54.
[0050] FIGS. 15-16 show a third preferred embodiment of the present
invention that comprises a main board 3a, a fixing plate 4a, a
brake plate 5a, and a support plate 6a.
[0051] Similarly to the second preferred embodiment, the main board
3a of the third preferred embodiment has a tail end facing to the
snow ground "S" and the tail end of the main board 3a is raised
with an angle. The fixing plate 4a is fixed on the tail end of the
main board 3a facing the snow ground "S" and the brake plate 5a is
attached to the main board 3a by the fixing plate 4a. Furthermore,
the fixing plate 4a is fixed to the main board 3a by a plurality of
fixing receptors 42a, such as bolts or snap rivets. The brake plate
5a has a shovel portion 50a and drain holes 51a. Because the
structures of the shovel portion 50a and the drain holes 51a are
the same as the second preferred embodiment, the detail
descriptions of the shovel portion 50a and the drain holes 51a are
omitted.
[0052] Differently from the second preferred embodiment, the fixing
plate 4a of the third preferred embodiment has a surface facing the
snow ground "S" and formed with a first fixing recess 40a. In
addition, the brake plate 5a of the third preferred embodiment is
partially fixed in the first fixing recess 40a of the fixing plate
4a and the brake plate 5a has a surface facing the fixing plate 4a
formed with a second fixing recess 500. The support plate 6a has
one end 61a integrated with the surface of the fixing plate 4a and
the other end 60a fixed in the second fixing recess 500 of the
brake plate 5a.
[0053] According to the descriptions of the second and the third
preferred embodiments, the connections between the fixing plate 4a,
the brake plate 5a and the support plate 6a could be optional by
other techniques.
[0054] Accordingly, the user only needs to press the brake plate
toward the snow ground to insert the shove portion into the snow
ground to produce a resistance, thereby providing a braking effect.
In addition, the user can operate the brake plate to brake the main
board easily and conveniently, thereby facilitating the user in
braking the main board. Further, the slider is portable and has a
smaller folded volume, thereby saving space of storage and
transportation. Further, the snow shoveled by the shovel portion of
the brake plate is drained outward from the drain hole. By applying
the brake plate to decelerate the sliding speed of the slider, the
snow drained outward from the drain hole provides special visual
effects to viewers.
[0055] Although the invention has been explained in relation to its
preferred embodiment(s) 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.
