PORTABLE MOTORCYCLE SUPPOR'T STAND
FIELD OF THE INVENTION
The present invention relates generally to motorcycle support stands, more
particularly to
portable motorcycle support stands.
BACKGROUND OF THE INVENTION
Description of the Prior Art
Most motorcycles have at least a kickstand attached to the motorcycle at one
side. The
kickstand swings out from a storage position, generally parallel to the
longitudinal axis of
the motorcycle, to an operating position, generally perpendicular to the
longitudinal axis
of the motorcycle. When the kickstand is to be used, it is moved from the
storage position
to the operating position and the motorcycle is tilted sideways so that a
distal end of the
kickstand touches the ground and keeps the motorcycle generally upright. An
apparent
drawback with these stands is that both wheels of the motorcycle still touch
the ground
and carry the bulk of the motorcycle weight. A further apparent disadvantage
is that the
motorcycle has to lean somewhat to one side in order for the motorcycle to be
in a stable
position, when it leans on the kickstand. The motorcycle is thus possibly
easier tipped
over, than if the stand had more than one support point to the ground. The
ground
furthermore has to be fairly solid, to prevent the kickstand from sinking into
it.
Certain motorcycles have a two support point stand fastened to the motorcycle.
These
stands are inherently more stable than the earlier described type of stands,
but usually
detract from the lowest height of the motorcycle and/or detract from the
aesthetics of the
motorcycle because of their often bulky appearance.
A jack for elevating a motorcycle so that either wheel is off the ground is
shown in US
5,639,067. The jack is relatively compact, for portability, but its
construction is complex,
with higher manufacturing costs and possible easier failure due to breakage as
results. The
jack has a main axle supported at each end by ground supports. A roller
mechanism is
pivotably attached parallel to the axis and is pivoted by the use of a ratchet
wrench (or

r F s
similar) applied to one end of the axle. This means the user :has to crouch
down adjacent
the axle to lift the motorcycle up onto the roller.
A motorcycle stand that is separate from the motorcycle is disclosed in US D
276,988.
This stand works according to the lever principle, having a portion that fits
under the
motorcycle and a lever to lift the motorcycle once the stand is tilted by the
lever. The
described stand has the apparent drawbacks of a weak construction and an
apparently
time-consuming way of disassembling the stand for storage, using a wing nut or
similar.
It is, therefore, desirable to provide a motorcycle stand, which is portable
and which can
be easily stored on the motorcycle when the stand is not in use, thus a stand
which does
not require a large space when stored.
SUMMARY OF THE INVENTION
It is an object of the invention to mitigate and/or obviate the above
mentioned
disadvantages to provide a portable motorcycle stand, which is small in
dimensions but
sturdy enough for heavy motorcycles, and is easy to operate and
assemble/disassemble.

DETAILED DESCRIPTION
Referring to Figs. 1 to 17, a first embodiment of a portable motorcycle
support stand 1 is
shown, having a main member 2 with a first protruding member 3 arranged at one
end of
the main member and a second protruding member 4, arranged at an opposite end
of the
main member. The first protruding member and the second protruding member are
protruding in the same general direction. Further, a movable cross-member 5 is
movably
arranged on the first protruding member 3 at one end 6 of the movable cross-
member 2
and on the second protruding member 4 at an opposite end 7 of the movable
cross-
member. Retaining means 8 are arranged on the first protruding member and on
the
second protruding member, to secure the movable cross-member 5 at a desired
position
along the first protruding member and the second protrudin;g member,
respectively. The
first protruding member and the second protruding member, are, for example,
threaded
bars onto which the movable cross-member is slidably mounted via through holes
9. The
retaining means 8 is then preferably nuts arranged one on each side of the
movable cross-
member as it is mounted onto the protruding members.
An an:ri 10 is movably arranged on the first protruding meinber 3. The arm is
movable
between a storage position, in which the arm is generally parallel to a
longitudinal
direction of the main member 2 (as shown in Figs. 3 and 7), and an operating
position, in
which a longitudinal direction of the arm is pivoted out at an angle from the
longitudinal
direction of the main member (as shown in Figs. 1, 2, 5, 6, 9 and 12 to 17).
The arm
further has a first end 15, which is arranged to slide over the first
protruding member, and
a second end 16, which is arranged to contact the ground or floor, when the
stand is in use
to support a motorcycle 100 (see Figs. 12 to 17).

CA 02368926 2002-01-22
In a first embodiment, the main member 2 has a first tower 11 and a second
tower 12
rigidly connected to each other by a stationary cross-member 113, the first
tower having the
first protruding member 3 arranged at one end of the first tower and the
second tower
having the second protruding member 4 arranged at one end of the second tower.
Advantageously, the stationary cross-member has weight-saving holes 17.
An arm hold-down means 14 is preferably movably arranged on the first
protruding
member 3, for preventing the arm from sliding on the first protruding member
3, when the
hold-down means is in. a locking position, and enabling the arm to slide on
the first
protruding member, when the hold-down means is in an un-locked position.
Advantageously, the arm hold-down means 14 is a threaded disc having a grooved
circumference for enhanced grip, the disc being easy to manipulate by screwing
it up or
down to either release or clamp down the arm to the first tower 11 on the
first protruding
member. Preferably, a first guide means 19 (see Fig. 4) is arranged on the arm
10
cooperating with a second guide means 18 (see Fig. 3) arranged on the first
tower, to fix
the arm when it is in the operating position. The first guide means is
preferably a
protrusion on the arm cooperating with a second guide means in the shape of a
notch on
the first tower.
Advantageously, the movable cross-member 5 has a soft cover 20, for preventing
damage
to the motorcycle when the stand is in use. Similarly, the first protruding
member
advantageously has a first end stop 21 and the second protruding member has a
second end
stop 22, for preventing damage to the motorcycle when the stand is in use or
being stored.
Figs. 18 to 27 show a second embodiment of a motorcycle stand according to the
invention. The difference compared to the earlier shown first embodiment is
that the
movable cross-member 5' does not have through holes but: has mounting studs 8'
into
which the threaded first protruding member 3 and the second protruding member
4 are
fixedly attachable. Nuts 8 are preferably used to secure the first and second
protruding
members in the respective stud. The first and second protruding members are
slidably and
removably held in holes 23 in the main member 2, so that the assembled movable
cross-
member with the first and second protruding members, 3 and 4 respectively, can
be moved
8

y. ' e
as a unit with respect to the main member. The height of the movable cross-
member is set
by adjusting the arm hold-down means 14, which is attached to both the first
protruding
member 3 and the second protruding member 4. To fold the arm 10 in its storage
position,
the hold-down means 14 of the first protruding member 3 is moved away from the
arm
and the arm swung to its storage position (see Fig. 20). All other technical
features are the
same as for the earlier described first embodiment, and use the same reference
numbers.
The second embodiment of the invention has the added advantage that the part
of the
movable cross-member 5', which contacts the motorcycle, is smooth without any
protruding parts to damage the motorcycle.
For all embodiments of the invention, the main member 2 is preferably made of
a light
metal alloy, for example an aluminum alloy and preferably casst. The arm is
preferably also
made of a light metal alloy, for example an aluminum alloy, and also
preferably cast.
Alternatively, the main member and the arm may be forged or machined, but
these metal
forming operations tend to be more expensive than casting.
It will be appreciated that the above description relates to the preferred
embodiment by
way of example only. Many variations on the invention will be obvious to those
knowledgeable in the field, and such obvious variations are within the scope
of the
invention as described and claimed, whether or not expressly described.
