BRAKING SYSTEM FOR SADDLE RIDING TYPE VEHICLE
FIELD OF THE TECHNOLOGY
[OOOI] The present invention relates to saddle riding type vehicles, and, more
particularly, to braking system of the saddle riding type vehicles.
BACKGROUND
[0002] Saddle riding type vehicles such as motorcycles, scooters, and the like
are provided with a side stand member to park 1 rest the vehicle when it is not in
use. In a conventional assembly, the side stand member is pivotally mounted with
the help of a stand mounting bolt onto a bracket which in turn is secured to a
lower portion of the vehicle main frame body such that the side stand member is
adapted to swing. The swing can be from a backward horizontal retreat position to
a forwardly inclined service position and vice versa.
[0003] If a saddle riding type vehicle is started with the side stand member
remaining in the forwardly inclined service position, the side stand member tends
to impinge on the road surface or the ground, thereby posing a threat to the safety
of a rider. This possibility becomes further acute when the saddle rising type
vehicle is leaned towards the side of the side stand member while negotiating a
turn.
[0004] In addition, when the saddle riding type vehicle is parked with the side
stand member in the forwardly inclined service position, on a surface having a
slope or otherwise, the saddle riding type vehicle tends to roll down. Hence, it is
preferable to apply a brake 1 parking brake. Commonly the saddle riding type
vehicles are not equipped with such parking brake device, even if so provided,
many a times, the rider forgets to actuate it.
[0005] European Patent Application 10251 626.7 titled "Parking Brake Device
For Motorcycle" discloses a parking brake device for a motorcycle that includes
an operation unit and a stand unit. The stand unit includes a kickstand operable
for pivoting between rest and parking positions, and a transmission cable having
opposite first and second ends fastened to the piston rod and the kickstand. The
piston rod moves from the free position to the brake position when the kickstand
pivots from the rest position to the parking position, and moves from the brake
position to the free position when the kickstand pivots from the parking position to
the rest position.
[0006] Japanese Patent Application Number 2008248678 titled "Braking
Device For Saddle-Riding Type Vehicle" discloses a braking device for a saddleriding
type vehicle that can restrict the turning of a rea'r wheel by a simple
structure. The braking device for the saddle-riding type vehicle includes a rear
disc brake, a wheel restriction means for restricting turning of the rear wheel, a
side stand member for standing the saddle-riding type vehicle and a turning
position detection means for detecting a turning position of the side stand
member. The wheel restriction means restricts the rear wheel or does not restrict
the rear wheel based on the turning position of the side stand member detected
by the turning position detection means.
[0007] However above stated systems I assembly / devices are complicated,
costly and difficult to assemble and involve more number of components or parts.
[0008] Japanese Patent Application number 200831 7654 titled "Stand Linkage
Brake" discloses a bicycle which can be parked safely even in inclined surface,
when stand is erected. A distal end above a fulcrum of the stand is swung to a
right side (rear side), and a wire connected to the distal end is pulled and a front
wheel brake is operated, when the stand is flipped rearward in riding, the brake is
released by a spring of the front wheel brake.
[0009] Japanese Patent Application number 10-082389 titled "Bicycle Parking
Stabilizing Unit" discloses an invention to stabilize the parked bicycles and
prevent rolling over, by putting brakes on the front wheel and by pulling a parking
brake wire through a spring, utilizing a motion of setting a stand at bicycle
parking.
[OOIO] Japanese Patent JP02220991A titled "Parking Brake Device With Side
Stand For Motorcycle" discloses a device where when a side stand member bar is
erected, the upper part of a side stand member pivot screw moves a brake lever,
and this brake lever moves with a side stand member pivot screw, a brake wire is
pulled to brake. When the side stand bar is returned, the brake lever is returned to
release the brakes.
[001 I] Chinese Patent Application number CN200920267992 titled
"Locomotive Parking Mechanism" provides an arrangement wherein a groove is
arranged at one end of the side foot stand for containing the internal line of the
braking lead. The internal line of the braking lead is connected to a parking device
via a rocker. A buckling element is fixed on a vehicle frame and the side foot
stand is pivoted on the buckling element. The buckling element is welded on the
vehicle frame. Such arrangement ensures stable parking of locomotive (such as
the saddle riding type vehicle) in slope road surface without toppling over.
[0012] However, in the above stated systems/devices/assemblies, a cable (or
a wire or a rope) is used for interlinking the brake with the side stand member.
Due to space constraint, it is difficult to fix such cables on to the side stand
member. Also, the harnessing and routing of the cable causes a lot of
complications.

DETAILED DESCRIPTION OF ACCOMPANYING DRAWINGS AND THE
PREFFERED EMBODIMENT
[0034] While the invention is susceptible to various modifications and
alternative forms, specific embodiment thereof has been shown by way of
example in the drawings and will be described in details below. It should be
understood, however that it is not intended to limit the invention to the particular
forms disclosed, but on the contrary, the invention is to cover all modifications,
equivalents, and alternative falling within the spirit and the scope of the invention.
[0035] The terms "comprises", "comprising", or any other variations thereof,
are intended to cover a non-exclusive inclusion, such that a setup, device or
method that comprises a list of components or steps does not include only those
components or steps but may include other components or steps not expressly

[0036] In accordance with the present invention the drawbacks as stated
hereinabove have been overcome by providing a side stand member actuated
braking system for a saddle riding type vehicle which is simple in construction and
operation and easy to mount and assemble such that when the side stand
member is in a forwardly inclined service position it actuates, partially or fully,
braking system of the saddle riding type vehicle.
[0037] For the better understanding of this invention, reference would now be
made to the embodiment illustrated in greater depth in the accompanying figures
and description here below, further, in the following figures, the same reference
numerals are used to identify the same components in various views.
[0038] The terms "front 1 forward", "rear", "up 1 upper'', "down I lower", "left",
"right" used therein represents the directions as seen from a vehicle driver sitting
astride and these directions are referred by arrows Fr, Rr, U, Lr, L, R in the
drawing figures. It may be noted that the terms "saddle riding type vehicle" or
"vehicle" are interchangeably used in the description and refers to the saddle
riding type vehicle such as a two-wheeled vehicle.
[0039] Figures 01 to 04 illustrate only components of the vehicle which are
pertinent to the scope of the present invention, however, those skilled in the art
would appreciate that the vehicle can obviously include various other parts.
Figures 01 to 04 depict, inter-alia, a main frame body (OI), a side stand member
(02), a main stand member (2a), a brake pedal (II), a brake assembly (04).
These Figures also show an engine (05), a stand bracket member (06), and a
brake link (15). The present invention provides a braking system (100) (shown in
Figure 07) including the brake pedal (1 I), a cam member (16) (shown in Figure
06), the side stand member (02) and a stand link (18). In an embodiment, the
vehicle is a saddle riding type vehicle such as a two-wheeled vehicle. Examples
of the vehicle include, but may not be limited to, motorcycles and scooters.
[0040] The side stand member (02) is pivotally attached to a left side of the
main frame body (01) of the vehicle. The side stand member (02) includes an
upper end and a lower end. The upper end of the side stand member (02) is
pivotally attached to a stand bracket member (06) using a stand mounting bolt
(07) (shown in Figure 05). In addition, the lower end of the side stand member
(02) is adapted to rest on the ground. Further, the stand bracket member (06) is
fixedly secured in an inclined manner with the lower portion of the main frame
body (01). The stand bracket member (06) is adapted to extend leftward and
downwardly from a welded surface of the stand bracket member (06) and the
main frame body (01).
[0041] The side stand member (02) is adapted to swing about an axis of the
stand mounting bolt (07), from / to a forwardly inclined service position (shown in
Figure 07 by dark continuous lines and indicated by the reference numeral (70))
to 1 from a backward horizontally retreat position (shown in Figure 07 by dark
phantom lines and indicated by the reference numeral (80)).
[0042] The side stand member (02), when in the backward horizontally retreat
position (80), is disposed substantially parallel to adjacent frame body portion. In
addition, the side stand member (02) includes a biasing spring (08). The biasing
spring (08) aids movement of the side stand member (02) from the forwardly
inclined service position (70) to the backward horizontally retreat position (80) and
vice versa. It may be noted that the biasing spring (08) is mounted on the side
stand member (02) according to the arrangements presently known in the art.
[0043] Referring to Figure 05, the side stand member (02) includes an upper
end and a lower end. The upper end of the side stand member (02) is bifurcated
thereof and defines an English letter "U" like structure formed by spaced apart two
leaves, for example, an inner leaf member (25) and an outer leaf member (26).
Each of the inner leaf member (25) and the outer leaf member (26) includes a
journaling hole entirely therethough.
[0044] The stand bracket member (06) having a bracket journaling hole (not
visible) is joined with the two leaves (25) and (26). The stand bracket member
(06) is joined with the two leaves by bringing the bracket journaling hole and each
of the journaling hole of the two leaves (25) and (26) in consonance.
[0045] The inner leaf member (25) of the side stand member (02) includes an
extended pin (09) having a loop (10) at its distal end. In an embodiment, the
extended pin (09) is fixedly mounted, preferably by welding or screwing or by
. another suitable mechanism presently known in the art, on the side stand
member (02). In another embodiment, an eye bolt can be used in place of the
extended pin (09). In an embodiment, the extended pin (09) / eye bolt is provided
on the body of the inner leaf member (25) of the side stand member (02). In an
embodiment, the extended pin (09) / eye bolt is provided on the body of the side
stand member (02).
[0046] As the stand bracket member (06) is mounted in an inclined manner,
the side stand member (02) moves away from the main frame body (01) with
respect to a vertical plane of the vehicle when it swings from the backward
horizontally retreat position (80) to the forwardly inclined service position (70).
The distance of any point on the side stand member (02) with respect to the
vertical plane of the vehicle increases with the degree of rotation of the side stand
member (02) from the backward horizontally retreat position (80) to the forwardly
inclined service position (70). Similarly, for any degree of rotation, the distance of
point on the side stand member (02) from the vertical plane of the vehicle
increases as one moves away from the stand mounting bolt (07).
[0047] Figures 03 and 04, illustrate, among other components, the brake pedal
(II), the brake link (15) and the brake assembly (04). The brake pedal (11) is
pivotally mounted on the right side to the lower portion of the main frame body
(01) using a mounting bolt (12). In one form, axis of the mounting bolt (12) is
substantially perpendicular to the longitudinal direction of the vehicle. This fulcrum
type brake pedal (1 1) includes a pedal arm (13) which acts as a load arm. The
pedal arm (13) includes a pedal plate (13a) at a free end. Operator can operate
the brake pedal (1 1) by placing foot on the pedal plate (13a) of the pedal arm
(13). The pedal arm (13) in the rear region extends upwardly to define an effort
arm (14) of the brake pedal (11) such that the brake pedal (11) exhibit fulcrum
effect about the mounting bolt (12). The brake link (15) is connected to an upper
free end of the effort arm (14) which actuates the brake assembly (04), for
example, the rear brake assembly of the vehicle.
[0048] As best seen in the Figure 03, the brake pedal (1 1) is pivotally coupled
to the main frame body (01) at such location that in an un-braked condition, a
central portion of the pedal arm (13) is below a lower rear portion of a down tube
(Id) of the main frame body (01) of the vehicle.
[0049] In an embodiment, when a rider presses the pedal arm (13) intending to
slow down or stop the vehicle by pressing hislher foot onto the pedal plate (13a),
the brake pedal (1 1) rotates clockwise about the mounting bolt (12) (when looked
from the right side). The pedal arm (13) moves downwards and the effort arm (14)
moves forward about the mounting bolt (12). The effort arm (14) pulls the brake
link (15) towards front side of the vehicle thereby actuating the brake assembly
(04) to slow down or stop the motion of rear wheel of the vehicle. Similarly, when
the rider lifts hisker foot from the pedal plate (13a) to release the pressure on the
brake pedal (II), the brake pedal (11) rotates in anticlockwise direction (when
looked from the right side), under the force of a brake retracting spring (not shown
in the figures), the pedal arm (13) moves upward and the effort arm (14) moves
rearward about the mounting bolt (12). The effort arm (14) pushes the brake link
(15) towards rear side of the vehicle to release the brake on the rear wheel and
allows the vehicle to move freely.
[0050] Referring to Figure 06, a bracket member (03) is fixed to the down tube
(Id) of the main frame body (01). It may be noted that the bracket member (03) is
fixed to the down tube (Id) by performing welding operations or any other process
presently known in the art. In addition, the cam member (16) is pivotally mounted
to the bracket member (03) using a cam pin (17) such that the side surface (16a)
of the cam member (16) slidably abuts against the pedal arm (13). In an
embodiment, the cam member (16) is free to rotate about an axis of the cam pin
(17) in a plane substantially in the transverse direction of the vehicle. In another
embodiment, the cam pin (17) is an integral member of the cam member (16) and
the cam pin (17) is pivotally hinged and rotatable about the bracket member (03).
In yet another embodiment, the cam member (16) can be pivotally connected
13
directly to the main frame body (01) of the vehicle. In an embodiment, the side
surface (16a) of the cam member (16) which slides on the pedal arm (13) is
coated with a metallic material or some other suitable material to aid its smooth
motion against the pedal arm (13).
[0051] Referring to Figure 07, the stand link (18) extends in cross direction of
the vehicle under the main frame body (01). A first end of the stand link (18) is
pivotally connected to the cam member (16). A second end of the stand link (18)
is hooked in the loop (10) formed at the distal end of the extended pin (09) such
that if the stand link (18) is pulled towards left side of the vehicle, the cam
member (16) rotates in the clockwise direction about axis of the cam pin (17)
when looked from the rear side of the vehicle. In an embodiment, the extended
pin (09) and the stand link (18) can be made as a single member.
[0052] Referring again to Figure 07, the extended pin (09) is nearest or in its
rightmost position (as indicated by the reference numeral 90 and depicted by
phantom lines) to the vehicle body when the side stand member (02) is in the
backward horizontal retreat position (80), since no force is exerted by the stand
link (18) on the cam member (16), the cam member (16) and the pedal arm (13)
lie in their topmost position (as indicated by the reference numeral 90a). The
brake pedal (1 1) rests in the normal position under force of brake retracting spring
where brake is not applied on the rear wheel.
[0053] When the rider intends to park the vehicle on the side stand member
(02) on a slope (or otherwise), and swings the side stand member (02) to the
forwardly inclined service position (70) (depicted by dark continuous lines in the
Figure 07), the extended pin (09) moves toward left direction along with the side
stand member (02). Since the side stand member (02) is swingable about an axis
which is inclined to the transverse axis of the vehicle, the extended pin (09)
moves toward left direction along with the side stand member (OZ), i.e. it moves
away from the vehicle. When the side stand member (02) fully swings to the
forwardly inclined service position (70), the extended pin (09) moves to the
farthest distance (as indicated by reference numeral (89)) from the vehicle, by a
distance as indicated by " X in the Figure 07. When the side stand member (02)
swings to the forwardly inclined service position (70), the extended pin (09) pulls
the stand link (18) towards left direction which in turn rotates the cam member
(16) about the cam pin (17) in clockwise direction (when looked from rear side of
the vehicle). The cam member (16) (which is in abutting relation with the pedal
arm (13)) starts sliding against the pedal arm (13) under the force exerted by the
left moving stand link (1 8).
[0054] When the cam member (16) rotates in a clockwise direction, it presses
the pedal arm (13) in downward direction. Accordingly, the brake pedal (11)
rotates clockwise about the mounting bolt (12) (when looked from the right side of
the vehicle). Accordingly, the pedal arm (13) moves downwards and the effort
arm (14) moves forward about the mounting bolt (12). When the side stand
member (02) fully swings to the forwardly inclined service position (70), the pedal
arm (13) reaches at its intended lowermost position (indicated by the reference
numeral 90b). The forwardly moving effort arm (14) pulls the brake link (15)
towards the front side of the vehicle thereby actuating the brake assembly (04) to
slow down or stop the motion of the rear wheel of the vehicle.
[0055] Thus, if the vehicle is parked on the side stand member (02) on the
slope surface or otherwise, with the side stand member (02) being in the
forwardly inclined service position (70), it automatically actuates the brake
assembly (04), partially or fully, to restrict the motion of the rear wheel of the
vehicle. Accordingly, the vehicle can be parked on the surface having a slope, or
otherwise, in a safe manner.
[0056] If the brake assembly (04) is already actuated (partially or fully) and the
rider intends to ride the vehicle (with the side stand member (02) still being in the
forwardly inclined service position (70)), the motion of the rear wheel of the
vehicle is restricted. The vehicle does not move at all or freely which provides an
indication to the rider that the side stand member (02) is in the forwardly inclined
service position (70) and should be swung into the backward horizontally retreat
position (80), thereby ensuring the safety to the rider and the vehicle.
[0057] Since the extended pin (09) on the side stand member (02) exhibits
revolving motion (about the stand mounting bolt (07)) as well as linear motion
(away and towards left side of the vehicle), the connection between the stand link
(18) and the cam member (16) is provided with sufficient play so as to make it
flexible. The degree of play is decided based on the distance at which the
extended pin (09) is disposed on the side stand member (02) from the stand
mounting bolt (07). In another embodiment, such play can also be provided
between the bracket member (03) and the cam pin (17) or the cam pin (17) and
the cam member (1 6).
[0058] The braking force on the rear wheel is a function of downward
movement of the pedal arm (13) or degree of clockwise rotation of the brake
pedal (11) (when looked froin the right side of the vehicle). In the present
invention, in the parking position, the braking force is a function of downward
movement of the pedal arm (13) which depends on profile of the cam member
(16), distance of connection point of the stand link (18) with the cam member (16)
from axis of the cam pin (17) and the distance at which the extended pin (09) is
disposed on the side stand member (02) from the stand mounting bolt (07). By
changing any of the above stated parameters or any combination, the braking
force on the rear wheel can be changed. Accordingly, the brake can be applied
either partially or fully as per the requirement.
[0059] In an embodiment, referring to the Figure 08, the cam member (16) is
provided with multiple mounting points (50) at different distances from the cam pin
(17) so that the braking force can be varied.
[0060] In yet another embodiment, referring to Figure 09, the stand link (18) is
divided into two parts as (18a) and (18b) which are interconnected by an elastic
member (1 8e). The elastic member (1 8e) can be a spring. The stand link (1 8) can
be divided into a plurality of parts which are connected using elastic members
such as the elastic member (18e).
[0061] Sometimes, due to space constraints it is required to dispose the
extended pin (09) at a greater distance from the stand mounting bolt (07) and
corresponding location on the cam member (16) is also not possible due to space
consideration, accordingly, in an embodiment, the elastic members (18e) is
designed with such an elastic constant that when the side stand member (02)
swings to the forwardly inclined service position (70), the total travel of the
extended pin (09) in the direction away from the vertical plane of the vehicle is
equal to the sum of the spring elongation and the cam member (16) travel
towards the left side.
[0062] In yet another embodiment, as illustrated in the Figure 10, the stand link
(18), which extends in cross direction of the vehicle under the main frame body
(OI), can be supported by at least one supporting member (79).
[0063] In yet another embodiment, as illustrated in the Figure 11, the stand
link (1 8) is realized in various forms. For example, ends of the stand link (18) may
be configured in variety of ways and shapes as per the requirement.
[0064] While considerable emphasis has been placed herein on the particular
features of this invention, it will be appreciated that various modifications can be
made, and that many changes can be made in the preferred embodiments
without departing from the principles of the invention. These and other
modifications in the nature of the invention or the preferred embodiments will be
apparent to those skilled in the art from the disclosure herein, whereby it is to be
distinctly understood that the foregoing descriptive matter is to be interpreted
merely as illustrative of the invention and not as a limitation.
[0065] Without in any way limiting the scope, interpretation, or application of
the claims appearing below, advantages of one or more of the exemplary
embodiments disclosed include provision of the braking system (100) that is the
side stand member actuated braking system. The braking system (100) retards or
restricts (partially or fully) the mobilization of the vehicle when the side stand
member (02) is in the forwardly inclined service position. In addition, the braking
system (100) stably parks the vehicle on the side stand member (02), on a slope
surface or otherwise, in a stable manner. Further, the present invention provides
the braking system (100) such that when the side stand member (02) is in the
forwardly inclined service position, it actuates, partially or fully, the braking
assembly (04) of the vehicle. Furthermore, the braking system (100) is simple in
construction and is easy to operate.
