Claims
What is claimed is:
1. A wheel mount for a skateboard comprising: a base plate adapted
to be mounted on a bottom of a platform of a skateboard; a
suspension body mounted on the base plate and a shock absorbing
device mounted between the base plate and the suspension body, the
suspension body including: a through hole laterally defined in and
extending through the suspension body, the through hole of the
suspension body including two opposite ends each having a series of
teeth extending from an inner periphery of the through hole in the
suspension body; and at least one bore defined in the suspension
body and communicating with the through hole in the suspension
body; a hollow axle extending through the suspension body and
partially received in the suspension body, the hollow axle
including: two series of teeth extending from an outer periphery of
the hollow axle and corresponding to the two series of teeth
extending from the periphery of the through hole in the suspension
body to prevent the hollow axle from rotating in the suspension
body; and a through hole defined in the hollow axle and aligning
with each at least one bore in the suspension body; and a pin
securely inserted into each at least one bore in the suspension
body and the aligning through hole in the hollow axle to prevent
the hollow axle from moving laterally.
2. The wheel mount for a skateboard as claimed in claim 1, wherein
the shock absorbing device is a resilient pad.
3. The wheel mount for a skateboard as claimed in claim 1, wherein
the pin is a spring pin.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a wheel mount, and more
particularly to a wheel mount for a skateboard.
[0003] 2. Description of Related Art
[0004] With reference to FIG. 4, a conventional wheel mount for a
skateboard in accordance with the prior art comprises a suspension
body (40) adapted to be mounted on a bottom of a platform (not
numbered) of the skateboard and an axle (41) extending through the
suspension body (40). The axle (41) is solid and includes two
opposite ends (not numbered). A wheel (42) is rotatably connected
to each end of the axle (41). At least one pin (44) extends into
the suspension body (40) and radially penetrates the axle (41) to
promote the stability between the axle (41) and the suspension body
(40).
[0005] However, the axle (41) bears any and all forces applied to
the skateboard. When the user performs a jump or other action that
results in the wheels (42) impacting an object, the axle (41) is
often deformed and out of order. Consequently, the strength of the
axle needs to be improved.
[0006] The present invention has arisen to mitigate and/or obviate
the disadvantages of the conventional wheel mount for a
skateboard.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide an
improved wheel mount for a skateboard.
[0008] To achieve the objective, the wheel mount includes a base
plate, a suspension body, a shock absorbing device and an axle. The
skateboard has a platform (not shown) with a top and bottom, and
the base plate is adapted to be mounted on the bottom of the
platform. The suspension body is mounted on the base plate, and the
shock absorbing device is mounted between the base plate and the
suspension body. A through hole is laterally defined in and extends
through the suspension body. The axle extends through the through
hole and is partially mounted in the suspension body. The axle
includes two opposite ends. A wheel is rotatably mounted on each
end of the axle.
[0009] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 is a perspective view of a wheel mount for a
skateboard in accordance with the present invention;
[0011] FIG. 2 is an exploded perspective view of the wheel mount
for a skateboard in FIG. 1;
[0012] FIG. 3 is a front cross sectional view of the wheel mount
for a skateboard; and
[0013] FIG. 4. is a side plan view in partial section of a wheel
mount for a skateboard in accordance with the prior art.
DETAILED DESCRIPTION OF THE INVENTION
[0014] With reference to the drawings and initially to FIGS. 1 and
2, a wheel mount (10) for a skateboard in accordance with the
present invention comprises a base plate (11), a suspension body
(12), a shock absorbing device (13) and a hollow axle (20). The
skateboard has a platform (not shown) with a top and bottom, and
the base plate (11) is adapted to be mounted on the bottom of the
platform. The suspension body (12) is mounted on the base plate
(11), and the shock absorbing device (13) is mounted between the
base plate (11) and the suspension body (12). In the preferred
embodiment of the wheel mount (10), the shock absorbing device (13)
is a resilient pad. A through hole (14) is laterally defined in and
extends through the suspension body (12) and has two opposite ends
(not numbered) with a series of longitudinal teeth (141) formed on
the inside of each end. The hollow axle (20) extends through the
through hole (14) and is partially mounted in the suspension body
(12). The axle (20) includes two opposite ends. A wheel (30) is
rotatably mounted on each end of the axle (20).
[0015] To securely mount the axle (20) in the through hole (14) and
keep the axle (20) from rotating, two series of longitudinal teeth
(21) are formed on the periphery of the axle (20) to correspond to
the teeth (141) inside the through hole (14). With additional
reference to FIG. 3, the suspension body (12) has at least one bore
(15) defined to diametrically communicate with the through hole
(14). The axle (20) has at least one through hole (22) defined to
correspond to the bore (15) in the suspension body (12). A pin (23)
securely extends through the bore (15) in the suspension body (12)
and the through hole (22) in the axle (20) to prevent the axle (20)
from moving laterally in the suspension body (12). In the preferred
embodiment of the present invention, the pin (23) is a spring
pin.
[0016] Since the axle (20) of the wheel mount (10) as previously
described is hollow, the strength of the axle (20) is promoted to
lengthen the useful life of the skateboard.
[0017] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
