Abstract
A lift for raising a motorcycle positioned on a surface of the lift includes a frame defining a wheel-way and a surface along a longitudinal path on the lift. A front end lift assembly includes a drive and is mounted to the frame for lifting the front portion of the motorcycle from the surface. A rear end lift assembly is mounted to the frame and includes a drive, independent of the front end drive, for lifting the rear portion of the motorcycle from the surface. The front and rear end lift assemblies are operable independently of one another so that the front portion of the motorcycle can be raised from the surface while the rear portion is on the surface, the rear portion of the motorcycle can be raised from the surface while the front portion is on the surface, and either the front or rear portion can be raised from the surface, independently of the other, and when the other portion of the motorcycle is raised from the surface.
Description
BACKGROUND OF THE INVENTION
The present invention pertains to a portable motorcycle lift. More particularly, the present invention pertains to a portable motorcycle lift that permits securely lifting the front and rear ends of the motorcycle independently of one another, and further permits stabilized securing of the of the motorcycle in an upright position.
Motorcycle jacks or lifts are known in the art. These devices are used to elevate a motorcycle in order to, for example, perform maintenance on the motorcycle, such as, engine repair, tire changing and the like.
Typically, it is desired to lift the motorcycle to an elevation at which it is comfortable for an individual to carry out such maintenance. This elevation can be from just a few inches off of the ground to a few feet off of the ground.
A wide variety of lifting devices are known in the art. Many such lifting devices use the motorcycle kickstand or rest to support the motorcycle during lifting and maintenance. This may not be desirable in that maintenance may be required to the stand, or the stand may not provide sufficient stability for carrying out the required maintenance. For example, if it is necessary to remove major components on the motorcycle, such as parts of the engine, stability over and above that provided by the stand is desirable, if not required. Additionally, these lifts do not permit positioning the motorcycle fully upright to, for example, drain all of the motor oil from the engine.
Other motorcycle lifts are known that simply elevate the entirety of the motorcycle from the wheels. While this may provide the desired elevation of the motorcycle, it may not provide the necessary stability vis-à-vis preventing the motorcycle from rolling. As such, these lifts can provide a hazard in that the elevated motorcycle can roll from the lift. In addition, such lifts do not provide the required access to the wheels to, for example, remove a wheel.
Still other lifts are known that use straps or the like to hold the motorcycle onto the lift. Again, these lifts suffer from the same stability drawbacks as those that utilize the motorcycle stands. Moreover, using tie-down straps generally requires that one or both the front and rear of the motorcycle is held to the ground or to the lift. Thus, these strap can preclude lifting either or both the front and rear of the motorcycle.
Still other lifts are known that provide the ability to lift either the front wheel or the rear wheel of the motorcycle; however, these lifts do not provide the ability to lift either or both the front and rear wheels, independently of one another, while the other wheel is either on the lift surface, or elevated from the surface.
Accordingly, there exists a need for a motorcycle lift that permits lifting either or both the front and rear wheels of a motorcycle, and further provides the ability to lift these wheels independently of one another. Desirably, such a motorcycle lift includes an arrangement by which the front wheel of the motorcycle is secured from rolling while the front wheel is lifted. Most desirably, such a motorcycle lift is portable and can be mounted for raising the entirety of the lift to elevate the lift with the motorcycle thereon to a desired height.
BRIEF SUMMARY OF THE INVENTION
A motorcycle lift raises an associated motorcycle positioned on the lift from a surface of the lift. The lift includes front and rear end lift assemblies that are operable independently of one another so that the front portion of the motorcycle can be raised from the surface while the rear portion is on the surface and so that the rear portion of the motorcycle can be raised from the surface while the front portion is on the surface.
Advantageously, either the front or rear portions of the motorcycle can be raised from the surface independently of the other and can be raised when the other portion of the motorcycle is also raised from the surface.
The lift includes a frame that defines a wheel-way along a generally longitudinal path on the lift. The wheel-way defines a surface for receiving the motorcycle.
A front end lift assembly is mounted to a front end of the frame. The front end lift assembly is operably connected to the motorcycle at a front end structural member (e.g., the lower triple clamp) and is configured for lifting the front portion of the motorcycle from the surface. The front end lift assembly is disposed at about a front end of the wheel-way and includes a front end lift drive. Preferably, the drive is an electric motor.
In a current embodiment, the front end lift assembly includes a front end drive bar that is operably connected to the frame. The frame provides a track and bearing surface for the drive bar.
In the current embodiment, the front end lift assembly includes a support carriage having symmetrical legs defining free ends and a transverse portion between the legs. The legs are pivotally connected to the drive bar.
A lift arm is mounted to the support carriage for connecting to the motorcycle. Preferably, the lift arm includes a pin for inserting into a lower triple clamp of the motorcycle front end. For stability and for maintaining the carriage upright, first and second opposed pivot arms each extend from the frame to one of the support carriage legs. The pivot arms provide a linkage between the support carriage and the frame.
The rear end lift assembly is mounted to the frame and is operably connected to the motorcycle at rear end structural members (e.g., at the motorcycle swing arms) for lifting the rear portion of the motorcycle from the surface. The rear end lift assembly is disposed at about a rear end of the wheel-way and includes a rear end lift drive.
In a current embodiment, the rear end lift assembly includes a rear end drive bar operably connected to the frame. The frame provides a track and bearing surface for the drive bar.
Support links are pivotally connected to the rear end drive bar. The support links are configured for connecting to the motorcycle rear end structural members for lifting the rear portion of the motorcycle from the surface. Preferably, mounting clips are mounted to the support links. The mounting clips can be V- or U-shaped member or clamp members for engaging the rear end structural member.
In a preferred embodiment, the lift includes a front wheel locking assembly. The locking assembly includes a pivoting saddle mounted to the frame along the wheel-way. The saddle has a concave shape and includes an entrance portion along the wheel-way. The entrance portion lies along the wheel-way for receiving the front wheel of the motorcycle. The saddle pivots between an entry position wherein the entrance portion lies on the surface and a locking position wherein the entrance portion is raised from the surface when the front wheel passes over and beyond the pivot.
The saddle can include a pair of angled arms extending outwardly from a top portion thereof. The arms center the front wheel and prevent the wheel (i.e., handle bars and steering mechanism) from pivoting out of a straight orientation. The front wheel locking assembly can include a wheel stop for engaging the front wheel when the motorcycle is moved onto the lift. The wheel stop can be configured as an upwardly extending, bent channel-shaped member for engaging the front wheel. An angled V-flange can be mounted to an upper end of the wheel stop, for capturing the wheel as it is moved into the stop.
In a current embodiment, the front and rear end lift drives are electric motors. The drives are independently operable and are operably connected to their respective drive bars by screw drives.
In a preferred lift, the front and rear end lift assemblies are pivotally connected to the frame and are pivotal downwardly onto the frame to fold flat. In this manner, the lift is readily prepared for storage and/or transport. The lift can be mounted to a scissor lift to raise the entirety of the lift upward from the ground. For local transport, casters can be mounted to the frame.
These and other features and advantages of the present invention will be apparent from the following detailed description, in conjunction with the appended claims.

DETAILED DESCRIPTION OF THE INVENTION
While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated. It should be further understood that the title of this section of this specification, namely, “Detailed Description Of The Invention”, relates to a requirement of the United States Patent Office, and does not imply, nor should be inferred to limit the subject matter disclosed herein.
Referring now to the figures and in particular to
FIG. 1
there is shown generally a motorcycle lift
10
embodying the principles of the present invention. The motorcycle lift
10
includes, generally, a frame
12
and an entrance ramp
14
. Mounted to the frame
12
, the lift
10
includes a front wheel locking assembly
16
, a front end lift assembly
18
, and a rear end lock and lift assembly
20
. The frame
12
defines a wheel-way W onto which the motorcycle is wheeled onto the lift
10
and along which the motorcycle is secured to the lift
10
when in use. The wheel-way defines a longitudinal path or axis A of the lift
10
.
As best seen in
FIG. 2
, the frame
12
includes a plurality of longitudinal and transverse members
22
a,b
and
24
a-d
that provide the necessary support, stability and rigidity to the lift
10
. Some of these structural components further provide functional operability to the lift
10
as will be described herein.
Referring now to
FIGS. 1
,
3
and
4
A-
4
C, the front wheel locking assembly
16
includes a pivoting saddle
26
that has a concave or arcuate shape that is configured for receiving the front wheel. A front portion
28
of the saddle
26
extends upwardly to prevent forward movement of the front wheel. A pair of angled arms
30
extend rearwardly and outwardly from about the front portion
28
to prevent the front wheel from pivoting (about its steering axis) when it is positioned in the saddle
26
. This lends further stability to the motorcycle when it is secured in the lift
10
.
The saddle
26
is mounted to the frame
12
along the wheel-way W. The saddle
26
includes a pivot pin
32
, and is configured to pivot between an entry position, as seen in
FIG. 4A
, and a locking position, as seen in FIG.
4
C. In the entry position, a rear portion
34
of the saddle
26
is flush with the surface S to permit rolling the front wheel onto the saddle
26
. In the locking position, the saddle
26
is pivoted forwardly. In this position, the rear surface
34
is elevated from the lift surface S and the front portion
28
of the saddle
26
pivots downwardly. In this manner, when the motorcycle is rolled onto the lift
10
and the front wheel moves on the saddle
26
beyond the pivot pin
32
, the saddle
26
pivots from the entry position to the locking position.
The front wheel locking assembly
16
further includes a wheel stop
36
positioned along the wheel-way W, forward of the saddle
26
. In a present embodiment, the wheel stop
36
is configured as a bent channel-like member in which the front wheel is held between the sides
38
a,b
of the channel
36
. An angled flange
40
, configured as a generally V-shaped member is mounted to an upper portion
42
of the wheel stop
36
. The angled flange
40
centers the wheel within the wheel stop
36
as the front wheel is rolled across the saddle
26
and into the wheel stop
36
. The bend
44
in the wheel stop
36
is rearwardly, i.e., toward the saddle
26
, so that as the front wheel is rolled across the saddle
26
it is secured between the wheel stop channel sides
38
a,b
and the pivoted (
FIG. 4C
) saddle
26
.
The lift
10
front end lift assembly, indicated generally at
18
, includes a drive bar
46
that is mounted transverse to the lift
10
and is configured to move longitudinally along the lift
10
. The drive bar
46
extends between outer structural frame members
22
a,b
. The frame members
22
a,b
provide a track as well as a bearing surface along which the drive bar
46
traverses.
The drive bar
46
is operably connected to a drive, such as the exemplary electric motor
48
. The drive
48
includes a linkage having a screw-type drive connection
50
between the drive bar
46
and the motor
48
. In this arrangement, the motor
48
rotates the screw
50
which is positioned in a threaded receptacle
52
in the drive bar
46
. As the screw
50
rotates, the drive bar
46
is driven longitudinally along the frame
12
between members
22
a,b
. Other drive arrangements, such as chains, belts, worm gear assemblies, gears, linkages, hydraulic and pneumatic drives, as well as manual (e.g., crank-type) drives and the like will be recognized by those skilled in the art and are within the scope and spirit of the present invention.
An inverted U-shaped support carriage
54
is mounted, at its legs or free ends
56
a,b
to the drive bar
46
. A transverse portion
58
of the carriage
54
extends parallel to the drive bar
46
above the lift surface S. The support carriage legs
56
a,b
are spaced apart and reside on either side of the motorcycle during lifting operation. In this arrangement, the support carriage
54
provides additional stability by distributing the weight of the motorcycle, during lifting, equally, transversely across the lift
10
, and away from the longitudinal centerline A of the lift
10
.
The support carriage legs
56
a,b
are pivotally mounted to the drive bar
46
, as indicated at
60
. A pair of brace arms
62
a,b
are pivotally mounted to the frame
12
, with one brace arm extending to each of the support carriage legs
56
a,b
. The brace arms
62
a,b
are pivotally mounted to the support carriage
54
and link the carriage
54
to the frame
12
to maintain the carriage
54
upright during the motorcycle front end lifting operation.
A lifting arm
64
is pivotally mounted to the transverse portion
58
of the support carriage
54
. The lifting arm
64
is mounted centrally on the carriage transverse portion
58
, generally parallel to and above the wheel-way W. The lifting arm
64
raises and lowers along with movement of the carriage transverse portion
58
. The lifting arm
64
is configured for securing to a structural member of the motorcycle (as will be described below) to elevate or lift the front end of the motorcycle. In a present embodiment, a lifting pin
66
extends upwardly from an end of the lift arm
64
. The pin
66
inserts into the motorcycle structural member for lifting.
The rear end lock and lift arrangement
20
includes a drive bar
70
, similar to the front end lift arrangement drive bar
46
. The rear end lift arrangement drive bar
70
extends transverse to the frame
12
and moves longitudinally therealong. The longitudinal frame members
22
a,b
provide a track as well as a bearing surface for movement of the drive bar
70
.
A drive arrangement
72
that includes, for example, an electric motor
74
and a linkage
76
having a screw-type drive connection
78
is operably connected to the rear end drive bar
70
. Other drive arrangements, such as chains, belts, worm gear assemblies, gears, linkages, hydraulic and pneumatic drives, as well as manual (e.g., crank-type) drives and the like, can be used for connecting the rear drive to the rear drive bar will be recognized by those skilled in the art and are within the scope and spirit of the present invention.
A pair of upstanding, pivotal support arms
80
a,b
are mounted to the rear end drive bar
70
. The rear support arms
80
a,b
are configured for attaching to a rear end portion of the motorcycle, preferably the rear wheel assembly at the swing arm. The mounting arrangement for the arms
80
a,b
can include, for example, a U or V-shaped clip, as shown at
82
that engages a peg P on the swing arm, a clamping assembly
83
, to support and clamp to the swing arm G (
FIGS. 5-7
) or the like for securing to the swing arm G. The clip arrangement
82
is preferable if a peg P is available in that it can be universally used with most motorcycles M.
The present lift
10
is quite versatile. It can be used as a stand to secure the motorcycle M in an upright position with both wheels on the lift surface (
FIG. 7
) to, for example, drain the motor oil. It can also be used to raise the front wheel off of the surface S, with the rear wheel on the surface S to, for example, remove the front wheel. It can also be used to raise the rear wheel off of the surface S with the front wheel on the surface S to, for example, remove the rear wheel. Lastly, it can be used to raise both the front and rear wheel off of the lift surface S.
In use, the motorcycle M is wheeled up to the entrance ramp
14
and is moved onto the lift
10
along the wheel-way W. The motorcycle M is wheeled forward until the front wheel enters the saddle
26
. Further urging the front wheel forward moves the front wheel along the saddle
26
so that the saddle
26
pivots forwardly (as seen in
FIG. 4C
) and so that the front wheel rests within the front wheel stop assembly
36
. In this position, the motorcycle M is secured to the lift
10
and is fully stable. As such, maintenance that does not require lifting the motorcycle M (but merely stability) can be performed when the motorcycle M is secured in this manner.
When using the lift
10
to elevate the front and/or rear of the motorcycle M, and prior to mounting the motorcycle to the lift
10
, the front drive bar
46
is in a retracted condition, i.e., toward a center of the lift
10
. The rear drive bar
70
can be in either a retracted condition (toward the center of the lift, FIG.
5
A), or in an extended condition (toward the rear of the lift, FIG.
6
A). In either condition, the point of attachment of the arm
80
to the motorcycle swing arm G, such as at peg P, cannot be immediately above the position of the drive bar
70
and arm base
82
a,b
. That is, the arms
80
a,b
cannot be vertical; rather they must be at an angle between the vertical and horizontal.
Referring now to the front portion of the lift
10
, when ready for lifting the front of the motorcycle M, the angle of the support carriage
54
to the horizontal is smallest, as seen in FIG.
7
. The lift bar
64
is then positioned so as to mount to a structural portion of the front end of the motorcycle M. Preferably, the lift bar lifting pin
66
is inserted into a lower triple clamp of the motorcycle at the pivot axis center. Those skilled in the art will recognize the triple clamp as that portion of the motorcycle at which the front fork bifurcates and that includes a tubular portion about which the front fork pivots.
With the lift arm pin
66
inserted into the triple clamp, and with the front wheel residing in the saddle
26
and in the front wheel stop assembly
36
, the rear support arms
80
a,b
are mounted to a structural portion of the motorcycle. Again, as set forth above, the rear arms
80
a,b
are preferably mounted to the swing arms G of the motorcycle. Those skilled in the art will recognize that the swing arms are those arms that extend generally along the motorcycle frame for attaching the rear wheel to the motorcycle frame.
The rear support arms
80
a,b
can be mounted to the motorcycle M in one of two ways. In either manner, the arms
80
a,b
are positioned at an angle to the lift
10
, with the bases
82
a,b
(that is, those portions of the arms
80
a,b
that are attached to the drive bar
70
), below and to the side (either front or rear of) the point of attachment P to the motorcycle, as seen in
FIGS. 5A and 6A
. In this manner, the arms
80
a,b
are at an angle to the vertical. With the rear support arms
80
a,b
mounted to the swing arms G, the motorcycle M is mounted to the lift
10
in a fully stable condition, and is ready for lifting.
In one front end lifting configuration (a tension lifting mode, as seen in FIGS.
5
A and
5
B), the rear support arms
80
a,b
are mounted to the motorcycle M with the bases
82
a,b
of the arms forward or inwardly of the point of connection P. That is, the bases
82
a,b
are closest to the forward end of the lift
10
. When lifting the front end of the motorcycle M from this position, the front drive
48
is actuated. The drive bar
46
moves forwardly along the frame
12
. As the drive bar
46
moves forwardly, the base of the support carriage
54
(which is mounted to the drive bar
46
, as indicated at
60
), is moved toward the front end of the lift
10
. In moving the drive bar
46
, the angle of the carriage
54
passes from an inclined position toward a vertical position.
As the carriage
54
moves toward the vertical, the carriage transverse portion
58
moves upwardly, that is away from lift surface S. Those skilled in the art will recognize that because the connections between the support carriage
54
, the drive bar
46
and the brace arms
62
a,b
are all pivoting connections, the entire front end lift assembly
16
moves to raise the carriage transverse member
58
. In that the transverse member
58
moves upwardly, the lift arm
64
moves upwardly as well. As the lift arm
64
moves upwardly, so too does the front end of the motorcycle.
During upward movement of the transverse portion
58
(and the motorcycle front end), the motorcycle M is “pulled” forward. To this end, because the rear end of the motorcycle is mounted to the rear support arms
80
a,b
(which pivot about the rear drive bar
70
), the rear end of the motorcycle will likewise lift from the surface S. As the lifting of the front of the motorcycle continues, the front wheel moves out of the saddle
26
and out of the wheel stop assembly
36
. As seen in
FIG. 7
, the wheel stop
36
can then be pivoted downwardly or moved out of the way (by disengagement from the frame,
FIG. 8
) to provide unobstructed access to the front wheel. It has been observed that even though the front wheel of the motorcycle is raised out of the saddle
26
and wheel stop assembly
36
, the present lift
10
maintains the motorcycle acceptably stable for carrying out maintenance or the like on the motorcycle.
In the other front end lifting configuration (a compression lifting mode, as seen in FIGS.
6
A and
6
B), the support arms
80
a,b
are mounted to the motorcycle M with the arm bases
82
a,b
rearwardly or outwardly of the point of connection P. That is, the bases are farthest from the forward end of the lift
10
. When lifting the front end of the motorcycle from this position, the front drive
48
is actuated. The drive bar
46
moves forwardly along the frame
12
. As the drive bar
46
moves forwardly, the base of the support carriage
54
(which is mounted to the drive bar
46
, as indicated at
60
), is moved toward the front end of the lift
10
. In moving the drive bar
46
, the angle of the carriage
54
passes from an inclined position toward a vertical position.
As the carriage
54
moves toward the vertical, the carriage transverse portion
58
moves upwardly, that is away from lift surface S. Those skilled in the art will recognize that because the connections between the support carriage
54
, the drive bar
46
and the brace arms
62
a,b
are all pivoting connections, the entire front end lift assembly
16
moves to raise the carriage transverse member
58
. In that the transverse member
58
moves upwardly, the lift arm
64
moves upwardly as well. As the lift arm
64
moves upwardly, so too does the front end of the motorcycle.
During upward movement of the transverse portion
58
, as the front end of the motorcycle M is raised off of the surface S, the rear of the motorcycle is maintained stable by the rear support arms
80
a,b
. More specifically, the angle of the rear support arms
80
a,b
(see FIG.
6
A), when they are linked or mounted to the motorcycle M is such that they provide stability to the motorcycle frame. Again, once the front end of the motorcycle M is raised from the surface, the front wheel moves out of the saddle
26
and out of the wheel stop assembly
36
, and the wheel stop
36
can be moved for unobstructed access to the front wheel.
As set forth above, the rear wheel can be lifted independently of the front wheel. Also analogous to the front lifting configuration and function, the rear wheel can be lifted in one of two different configurations; however, in both of these configurations, the front wheel is maintained in the front wheel locking assembly
16
.
In a first rear end lifting configuration, the rear support arms
80
a,b
are mounted to the motorcycle with the arm bases
82
a,b
forward or inwardly of the point of connection P. That is, the bases
82
a,b
are closest to the forward end of the lift
10
. Actuating the rear end drive assembly
72
to move the rear drive bar
70
rearwardly moves the rear support arms
80
a,b
, which are at an angle relative to the vertical (see
FIG. 5A
) rearwardly, and at the same time pivots the arms
80
a,b
toward an upright or vertical orientation (see FIG.
5
B).
This movement of the rear support arms
80
a,b
raises the rear end of the motorcycle M. When this lifting mode is used, the front wheel can be secured to the front wheel stop
36
by, for example, a strap or the like (not shown). As will be recognize by those skilled in the art, because this mode of lifting “pulls” the motorcycle rearwardly, the front wheel tends to pull out of the cradle
26
and wheel stop
36
. Strapping the front wheel to the wheel stop
36
prevents disengagement of the wheel from the stop
36
.
In a second rear end lifting configuration, the rear support arms
80
a,b
are mounted to the motorcycle with the arm bases
82
a,b
rearwardly or outwardly of the point of connection P. That is, the bases
82
a,b
are closest to the rear end of the lift
10
. Actuating the rear end drive assembly
72
to move the rear drive bar
70
forwardly moves the rear support arms
80
a,b
, which are at an angle relative to the vertical (see
FIG. 6A
) forwardly, and at the same time pivots the arms
80
a,b
toward an upright or vertical orientation (see FIG.
6
B). This movement of the rear support arms
80
a,b
raises the rear end of the motorcycle. When this lifting mode is used, the front wheel need not be secured to the front wheel stop
36
. As will be recognize by those skilled in the art, because this mode of lifting “pushes” the motorcycle M forwardly, the front wheel is further urged into the wheel stop

Advantageously, it has been found that the present lift
10
can be used to raise the rear end of the motorcycle whether the front end is raised or on the surface S. Because the front end of the motorcycle is support from about the triple clamp (which is generally above the center of gravity of the motorcycle), it is stable when both the front and rear wheels are raised from the wheel-way.
As will be appreciated by those skilled in the art, because of the pivoting connections at the front end lift assembly
16
and the rear end lift assembly
20
, all of the members of these assemblies can be folded downwardly to rest on the frame
12
. In addition, the front wheel stop assembly
36
can be removed from the frame
12
and/or folded downwardly onto the frame
12
. In this manner, the entire lift
10
can essentially be folded down for storage or transport. A present lift
10
can be folded down to less than about 12 inches for storage when it is not in use or for transport to a desired location.
As will also be understood by those skilled in the art, the connections between the support carriage
54
and the front drive bar
46
, the support carriage
54
and the brace arms
62
a,b
, the lifting arm
64
and the support carriage
54
, the rear support arms
80
a,b
(vertically, as indicated at
84
,as well as transversely, as indicated at
86
, along the rear drive bar
70
, and at the clamps
82
), the front wheel stop
36
to the frame
12
and the saddle pivot
32
within the frame
12
are all adjustable by a variety of openings in the various members and pins insertable and lockable therein. This myriad adjustability permits use of a single lift
10
that can accommodate essentially any type of motorcycle.
As set forth above, the present lift
10
is fully portable. To this end, casters
88
(rear only shown) can be mounted to the bottom of the lift
10
so that the lift
10
can be wheeled from one location to another. In addition, a scissor jack or other known elevating device (not shown) can be mounted to the bottom of the lift
10
to elevate the entire lift
10
above the ground to provide additional working height to the lift
10
. Also, as will be appreciated by those skilled in the art, the present lift
10
can be mounted to a flat bed or the like so that it can be readily transported from one location to another and set up for use. For example, the lift
10
can be loaded onto a truck and can be moved from a shop to a desired destination, such as a motorcycle racing venue.
As will also be appreciated by those skilled in the art, as discussed above, the lift
10
can be used as a stand for performing maintenance on the motorcycle, without lifting the motorcycle. For example, to change the motor oil, the motorcycle need not be lifted; rather, the motorcycle merely needs to be secured in an upright position. To this end, the front wheel locking assembly
16
(saddle
26
and wheel stop
36
) can be used (without the front end lift arm
64
engaged and without the rear end lift arms
80
a,b
engaged) to secure the motorcycle in place. This is, it has been found that with the front wheel resting in the saddle
26
and within the front wheel stop
36
, the motorcycle is sufficiently stable to conduct many non-lift-required maintenance procedures.
In the present disclosure, the words “a” or “an” are to be taken to include both the singular and the plural. Conversely, any reference to plural items shall, where appropriate, include the singular.
From the foregoing it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present invention. It is to be understood that no limitation with respect to the specific embodiments illustrated is intended or should be inferred. The disclosure is intended to cover by the appended claims all such modifications as fall within the scope of the claims.
