embodiment, the second lower lock pin (135) and second coupling clamp (137) provided
on bed part (130) of a dependently movable leg assembly (109) project in opposite
directions.
[0068] As illustrated in Figure 06, the second rib member ( 131) is fixed on the bed part
(130) along the length of the bed part (130). The second rib member (131) welded to the
bed part (130) along one of its side edge. The second rib member (131) has width (ww).
The width (ww) of the second rib member (131) is variable and continuously decreasing
along the length of bed part (130). In an embodiment, the width (ww) of second rib
member (131) is greatest at upper end of bed part (130). In an embodiment, the width
(ww) of second rib member (131) is uniform from its upper end to lower end. In an
embodiment, the second rib member (131) is an integrated part of dependently movable
leg assembly (109).
[0069] The second rib member (131) at its upper end is provided with a tubular member
(138). In an embodiment, tubular member-(138) is integral with the second rib member
(131). The tubular member (138) is a hollow cylindrical body having length as L1 and
diameter as Dl. The longitudinal axis B-B of tubular member (138) extends in the width
direction of vehicle. At the intermediate portion along the length of tubular member
(138), there is provided a collar (139). The collar (139) is extending radially outwards
from the tubular member (138). In an embodiment, the collar (139) is circular. In an
embodiment, the collar (139) is of any other suitable shape. The collar (139) is preferably
welded onto the circumferential surface of tubular member (138).
(0070] The internal diameter D of the linking member (! 28) is greater than the diameter
D1 of tubular member (138) of dependently movable leg assembly (109) i.e. D>Dl. The
length L of linking member (128) is approximately equal to the length L1 of tubular
member (138).
(0071] Figure 08 ·illustrates an exploded view of stand device (02) according to an
embodiment of the present invention. The cross member (117) is a tubular bar. The cross
15
~IPO DELHI 28-@1-2015 16:37
member (11 7) has outer diameter as 02 and length as L2. The cross member (117) at its
one end is provided with a head portion greater in dimensions than that of diameter 02.
The cross member (117) at its other end is provided with a drive pin engaging hole
(117a). The diameter D2 of cross member (117) is lesser than the diameter D1 of tubular
member (138) i.e. 01>02. The length L2 of the cross member (117) is greater than the
length Ll oftubular member (138) and the length L of linking member (128).
[0072] As illustrated in Figure 08, the linking member (128) is disposed within the
receiving provision (126) of the independently movable leg assembly (1 08) aligning the
insertion hole (141a) of linking member (128) with the first opening (127a) and the
second opening (127b) of walls (126a) and (126b). The axle pin (129) is then inserted
through the first opening (127a) which then passes through the insertion hole (141a) and
then the second opening (127b). In an embodiment, the axle pin (129) is press fitted into
the engaging openings (127a) and (127b). Such disposition of linking member (128)
allows the independently movable leg assembly (108) to pivot about the axle pin (129).
[0073] The independently movable leg assembly (108) is assembled to the dependently
movable leg assembly (109) through rotatably inserting the tubular member (138) into the
cylindrical portion (140) of the linking member (128). The linking member (128) can
rotate about the tubular member (138).
· [0074] The length of tubular member (138) inserted through the cylindrical portion
(140) of linking member (128) is L3 which is equal or lesser than the length L of
cylindrical portion (140) of linking member (128). In the preferred embodiment, the
length L3 of linking member (138) is approximately equal to the length L of linking
member (128). The length L3 is measured from the left end portion of tubular member
(138) which enters the linking member (128) to the collar (139).
[0075) The assembly ofthe independently movable leg assembly (108) and dependently
movable leg assembly (109) is mounted to the body frame (100) using a cross member
(117) such that the independently movabk leg assembly (108) and dependently movable
leg assembly (109), independently or dependently, can rotate about the axis of the cross
member (117).
[0076] The assembly ofthe independently movable leg assembly (108) and dependently
movable leg assembly (109) is brought in the space confined between the left support
plate member (110) and right support plate member (111). The longitudinal axis B-B of
16
_·TPO DELHI 28-GI-2015 15:37
tubular member (138) is aligned with the first circular aperture (112) of the left support
plate member (110) and second circular aperture (114) of the right support plate member
(111 ).
(0077] The cross member (117) is inserted through the circular aperture (114) of the
right support plate member (111). The cross member (117) then inserted through the
tubular member (138) ofthe dependently movable leg assembly (109). The cross member
(117) then inserted through the circular aperture (112) of left support plate member (110).
[0078] The upper end of the first spring member (124) is hooked with first lock pin
(113) of the independently movable leg assembly (108) and lower end of first spring
member (124) is hooked with first lower lock pin (123) of the independently movable leg
· assembly (1 08). Similarly, the upper end of second spring member (136) is hooked with
second lock pin (115) of the dependently movable leg assembly (109).and lower end of
second spring member (136) with second lower lock pin (135) of the dependently
movable leg assembly (109).
:.~'- [0079] The cross member (117) is inserted entirely till the head portion of cross
;o;:.1. ., member (117) hits the right support plate member (111) from the right side. Once the
:c~'· cross member (117) extends out from the first circular aperture (112), a drive pin (144) is
·.:,,;;.. then inserted in the drive pin engaging aperture (143) which restricts the movement of the
·.· cross member (117) along axis ofthe cross member (117) .
.·, f:. (0080] Since, the axes of cross member (117), tubular member (138) and linking
member (128) are co-axial with the first circular aperture (112) of left support plate
member (110) and second circular aperture (114) of right support plate member (111), the
stand device (02) has a common axis (C-C).
(0081] In an embodiment, maximum pivotal movement of the independently movable
leg assembly ( 1 08) allowed by the linking member ( 128) is equal to the angle formed by
the conventional side stand bracket with the vertical plane of a vehicle.
(0082] Figure 08 illustrates a schematic view of the stand device (02) in a retracted
position. The stand device (02) when in the retracted position, the independently movable
leg assembly (108) and dependently movable leg assembly (109) lie, preferably,
unengaged. The cross bar (116) of the independently movable leg assembly (108) lies
protruding outwardly with respect to the frame body (100). In the retracted unengaged
position of stand device (02), the independently movable leg assembly (108) is capable of
17
IPD DELHI 28-8-l-2G15 1&;37
independent movement when actuated by the rider. The independent movement of
independently movable leg assembly (1 08) involves movement from the retracted
(rearward) position to an extended (parked) position. Actuation of independently movable
leg assembly (108) to its extended (parked) position causes the independently movable
leg assembly (1 08) to function as side stand supporting the two wheeled vehicle in parked
conditions.
(0083] Referring to Figure 08 and Figure 09 illustrate the change in the position of the
independently movable leg assembly (1 08) from a retracted (rearward) position to an
extended (parked) position whilst acting as a side stand .. In the retracted position, the rider
for parking the vehicle in a side stand position, places his foot on the cross bar (116) of
the independently movable leg assembly (108). The rider applies force in the downward
direction on the cross bar (116) and forces the independently movable leg assembly (108)
to rotate from its retracted (rearward) position towards the extended (parked) position.
The trajectory covered by independently movable leg assembly (1 08) is arcuate from its
retracted position to extended position.
[0084] In the retracted unengaged position of independently movable leg assembly
(108) (of stand device (02)), the independently movable leg assembly (108) lie in an
inclined manner with the extended side surface (141c) of linking member (128) abutting
the dimension of receiving provision (126). When in retracted unengaged position, the
independently movable leg assembly (108) can move towards the dependently movable
leg assembly (1 09) upon application of force in the width direction of vehicle and also
can move from its retracted to extended (parked position).
(0085] The application of force on cross bar (116) in the downward direction causes
the independently movable leg assembly (1 08) to rotate about the. axis (C-C) of the stand
device (02) at the same time the linking member (128) also rotate about the axis (B-B) of
the tubular member (138) without causing any movement of tubular member (138). The
independently movable leg assembly (108) when pushed downwards due to application of
force covers an arcuate path rotating about the axis (C-C) of stand device (02). The
arcuate movement of the independently movable leg assembly ( 1 08) is further facilitated
by the first spring member (124). Once the independently movable leg assembly (108)
moves downwards, the vehicle is leaned towards its left so that the vehicle can be parked
18
- :IPO DELHI. 28- Cll- 2015: 16 3-7
in a side stand position. When the vehicle is in parked condition the foot pad part (122)
comes into contact with the ground surface.
[0086] At anytime during parked position of vehicle in the side stand position, the rider
wishes to bring the vehicle back to its normal position, the independently movable leg
assembly (108) is moved from its parked position (extended position) to the retracted
position. The movement of vehicle back to its normal position moves the linking member
(128) about the axis (B-B) of tubular member (138).
[0087] The independently movable leg assembly ( 1 08) is moved to its retracted position
by application of force on the cross bar ( 116) or the base part (118). The application of
force causes the independently movable leg assembly (108) to rotate in counterclockwise
direction, when viewed from left side, along the axis (C-C) of stand device (02). The
transition of independently movable leg assembly (108) back to its retracted position is
facilitated by the first spring member (124). During the transition of independently
movable leg assembly (108) back to its retracted position, the cylindrical portion (140) of
linking member (128) rotate about the axis (B-B) of the tubular member (138) without
causing any movement of tubular member (138).
[0088] Figure 08 and Figure 10 illustrate the change in the position of stand device
from its retracted position to extended position when acting as a centre stand. To deploy
the stand device (02) in the centre stand configuration, the independently movable leg
assembly (1 08) and dependently movable leg assembly (1 09) are to be coupled together
through their first coupling clamp (125) and second coupling clamp (137). Here, the first
coupling clamp (125) and second coupling clamp (137) are removable only in the
retracted position of the independently movable leg assembly (1 08). And the first
coupling clamp (125) and second coupling clamp (137} do not separate.from each other
under any forces when the independently movable leg assembly (108) and dependently
movable leg assembly (109) are in extended position. This ensures that when vehicle is
. parked on the centre stand the independently movable leg assembly (108) do not tilt and
maintains the vertical position of the vehicle. The independently movable leg assembly
(108) is then pushed downwards moving in clockwise direction, when viewed from left
side, covering an arcuate path about the axis (C-C) of stand device (02).
[0089] Coupling of independently movable leg assembly (108) with dependently
movable leg assembly (109) is facilitated by the rider placing his foot on the cross bar
19
LPO rrELHI 28-01-201S 1s:37
(116) or base part (118) of independently movable leg assembly ( 1 08) and pushing it in
the width direction of vehicle, in the instant embodiment, since the independently
movable leg assembly ( 1 08) is on the left side, hence the independently movable leg
assembly ( 1 08) is pushed towards right direction of the vehicle. The application of force
on the independently movable leg assembly (108) causes the independently movable leg
assembly (1 08) to move inwards in the width direction of vehicle, thereby leading the first
coupling clamp (125) to come into proximity of second coupling clamp ( 13 7) of
dependently movable leg assembly (109). In an embodiment, the independently movable
leg assembly (108) and the dependently movable leg assembly (109) are mounted in such
way that, when the independently movable leg assembly (1 08) is moved inwards in the
width direction of vehicle the independently movable leg assembly ( 1 08) lie rearwards of
the dependently movable leg assembly (1 09), more particularly, in the instant
embodiment, the first coupling clamp ( 125) stay rearwards of the second coupling clamp
(137) of dependently movable leg assembly (109). In an embodiment, the inward
movement of independently movable leg assembly (108) in the width direction ofvehicle
is limited by extended side surface (141d) of linking member (128). The first coupling
··· clamp (125) and second coupling clamp (137) are having clamping ridge (125a) and
'· (137a), when rider releases the force from the independently movable leg assembly (108)
in the width direction of vehicle, the independently movable leg assembly (1 08) tends to
· · · move towards left direction of vehicle, this motion if the independently movable leg
assembly (108) is restricted by the engaged clamping ridge (125a) and (137a) of the first
coupling clamp (125) and second coupling clamp (137). This ensures that when the
vehicle is parked on centre stand configuration, the independently movable leg assembly
(1 08) does not tilt under any force. Also, the efforts I force required by user while
removing the first coupling clamp (125) and second coupling clamp (137) from each
other is very less that any average person can remove the first coupling clamp (125) and
second coupling clamp (137). While removing the first coupling clamp (125) and second
coupling clamp (137) from each other, the user has to slightly press the independently
movable leg assembly (108) inward in the width direction of the vehicle and backward
and release the force, the independently movable leg assembly (108) under the force of
first spring member (124) will move in its default position i.e. side stand configuration:

. ·.-~
[0090] As the first coupling clamp ( 125) and second coupling clamp (13 7) are engaged
now, further application of force by the rider, in downward direction, causes the
independently movable leg assembly (1 08) and dependently movable leg assembly ( 1 09)
to rotate from the retracted (rearward) position towards the extended (parked) position.
The trajectory covered by the engaged assembly of independently movable leg assembly
(1 08) and dependently movable leg assembly (1 09) is arcuate from the retracted position
to extended position.
[0091] To support the vehicle in centre stand position, rider applies force acting in the
downward direction on the cross bar (116) or base part (118) of the independently
movable leg assembly (108). On application of force on cross bar (116) in the downward
direction the independently movable leg assembly (108) tends to rotate about the axis (C-
. C) of stand device (02) in the clockwise direction when viewed from the left side. Now,.
since the independently ~ova?le leg assembly (108) and the dependently movable leg
assembly ( 1 09) are engaged, the clockwise rotating movement of independently movable
leg :assembly (108) also cause dependently movable leg assembly (109), the linking
member (128) and the tubular member (138) to rotate about the axis (C-C) of stand device
(02).
[0092] The independently movable· leg assembly and dependently movable leg
assembly (1 09) when pushed downwards due to application of force covers an arcuate
path in the clockwise direction, when viewed from left side, around the axis (C-C) of
stand device (02). The arcuate movement of the independently movable leg assembly and
dependently movable leg assembly (109) is aided by first spring member (124) and
second spring member (136). In the parked position of vehicle supported by centre stand,
the crown part (133) of dependently movable leg assembly (109) and head.part (118a) of
independently movable leg assembly (108) abuts the frame body (100) of vehicle. During
parked condition of vehicle in centre stand position, the crown part (133) and head part
( 118a) becomes the point of contact.
(0093] To set the stand device (02) back to its retracted position, the vehicle needs to be
pushed forwardly rotating the stand device (02) in counterclockwise direction about the
ax~s (C-C) of the stand device (02). Once the stand device (02) is rotated back to its
retracted (rearward) position, the independently movable leg assembly (1 08) gets
decoupled from the dependently movable leg assembly (1 09). In an embodiment, the
C} decoupling of independently movable leg assembly ( 1 08) from dependently movable leg
assembly (109) happens due to tension in the first spring member (124). Back to the
retracted position, the independently movable leg assembly (1 08) becomes free again to
be engaged again either as side stand or for centre stand assembly.
[0094] As stated in the foregoing, the present invention is capable of providing a stand
device which functions both as side stand and centre stand.
[0095] The present invention provides a stand device which is cost effective.
