DESC:FIELD OF THE INVENTION
[0001] The present invention relates generally to two-wheeled vehicles and particularly, but not exclusively, to a rear turn signal lamp assembly.

BACKGROUND
[0002] A two-wheeled vehicle has rear turn signal lamps, at least one on each side of the two-wheeled vehicle, to indicate the intention of a rider when taking a turn, either to the left or to the right. The indication allows drivers of automobiles behind the two-wheeled vehicle to know to take note of the rider’s intended direction.
[0003] Conventionally, the rear turn signal lamps are mounted on the two-wheeled vehicle in a manner such that the rear turn signal lamps project outward and are positioned beyond the two-wheeled vehicles main body. Such a position for the rear turn signal lamps renders the same vulnerable to damage due to an increased risk of impact, especially when the two-wheeled vehicle is ridden in areas of traffic congestion and when the vehicle capsizes and also, the presence of tungsten filament in the rear turn signal lamp decreases the response of the drivers and also, the chances of being struck increases.

DETAILED DESCRIPTION OF THE INVENTION
[0011] Generally, a two-wheeled vehicle is provided with rear turn signal lamps, mounted to protrude outside a main body of the two-wheeled vehicle. The arrangement prevalent in the state of the art is designed to ensure visibility of the rear turn signal lamps to automobile drivers trailing the two-wheeled vehicle.
[0012] However, the arrangement customarily adopted tends to leave the rear turn lamps exposed to be hit and thereby, damaged. The probability of incidence of impact on the rear turn lamps is greater on account of the extent to which the rear turn lamps are located away from the main body of the two-wheeled vehicle.
[0013] Moreover, the rear turn signal lamps are conventionally mounted directly on a rear fender or on the frame or the rear fender through flexible extensions adapted to secure a rear turn signal lamp on one end and the frame or the rear fender on another end. The prevalent rear turn signal lamp mounting assembly is disadvantageous due to the need to use the flexible extensions which add to the total component count. The flexible extensions are necessary to prevent the rear turn lamps from breaking or damaging on first impact or an impact force of low magnitude.
[0014] Therefore, a rear turn signal lamp assembly which allows a plurality of rear turn signal lamps to be mounted on a two-wheeled vehicle without exposing the plurality of rear turn signal lamps outside the contours of a main body of the two-wheeled vehicle, while ensuring visibility of the plurality of rear turn signal lamps, is desirable in the art.
[0015] The present invention provides a rear turn signal lamp assembly of a two wheeled vehicle comprising a plurality of rear turn signal lamps, and the plurality of rear turn signal lamps being mounted to a pair of side covers.
[0016] In an embodiment, the pair of side covers includes a left panel member and a right panel member. The plurality of rear turn signal lamps includes at least one left turn signal lamp and at least one right turn signal lamp. The at least one left turn lamp is disposed on the left panel member of the two wheeled vehicle and at least one right turn signal lamp is disposed on the right panel member of the two wheeled vehicle.
[0017] In an embodiment, the left panel member and right panel member of the two-wheeled vehicle include an inner recess portion each. The inner recess portion is configured to be covered from the sides and visible when viewed from a rear side of the vehicle.
[0018] In an embodiment, at least one left turn signal lamp is mounted in the inner recess portion of the left panel member and at least one right turn lamp is mounted in the inner recess portion of the right panel member. The arrangement, as disclosed in the present embodiment, ensures visibility of the plurality of rear turn signal lamps to drivers of automobiles trailing the two-wheeled vehicle.
[0019] In an embodiment, the plurality of rear turn signal lamps is fastened to the left panel member and the right panel member through one or more fasteners. The one or more fasteners, in the present embodiment, are disposed behind each of the inner recess portion of the left panel member and the right panel member. The rear turn signal lamp assembly, as disclosed, has the advantage of dispensing with additional components to facilitate mounting of the plurality of rear turn signal lamps to the two-wheeled vehicle.
[0020] In an embodiment, the left panel member and the right panel member each are configured to have a quadrilateral or rhomboidal shape so as to protect the plurality of rear turn signal lamps disposed in each of the inner recess portion of the left panel member and the right panel member and also allow visibility of the plurality of rear turn signal lamps when viewed from either side of the rear of the two-wheeled vehicle. The quadrilateral or rhomboidal shape of the side covers enlarges the range of visibility of the plurality of rear turn signal lamps from a left rear side to a right rear side.
[0021] In an embodiment, a corner each of the quadrilateral or rhomboidal shaped plurality of side covers, including the left panel member and the right panel member, is adapted to form a cantilever end at each of the plurality of side covers. The cantilever end being a corner, as disclosed in the present embodiment, ensures that a side of the quadrilateral or rhomboid shaped left panel member and right panel member have an upper side sloping down towards the corner. The arrangement where an upper side slopes down, ensures that at least one left rear turn signal lamp, which is housed in the inner recess of the left panel member is visible from a left rear side and at least one right rear turn signal lamp, which is housed in the inner recess of the right panel member is visible from a right rear side.
[0022] Therefore, the range of visibility of the plurality of rear turn signal lamps is not restricted to a narrow range of perpendicular rear view of the two-wheeled vehicle.
[0023] Thus, the present subject matter provides a rear turn signal lamp assembly for a two-wheeled vehicle comprising a plurality of rear turn lamps, including at least one left turn lamp and at least one right turn lamp, the plurality of rear turn lamps being disposed, with ensured wide range of visibility to vehicles trailing the two-wheeled vehicle, in each of an inner recess of a left panel member and a right panel member.
[0024] An advantage of the present invention is the dispensing with the need to provide additional mounting components such as flexible extensions, as prevalent in the state of the art, to reduce impact of external force incident on the rear turn lamps conventionally positioned away from the main body of the two-wheeled vehicle. The number of components are reduced in the present invention, thereby reduces cost of manufacture and increasing ease of assembly.
[0025] The present invention discloses a real turn signal lamp assembly that ensures protection of the plurality of rear turn lamps by locating them within the contours of the main body of the two wheeled vehicle, thereby projecting plurality of turn lamps from being mounted at an exposed location.
[0026] The present invention simultaneously ensures visibility of the plurality of the rear turn signal lamps from a wide range when viewed from the rear of the two wheeled vehicle, thereby not obstructing the view of the plurality of rear turn lamps for drivers of automobiles trailing the two wheeled vehicle.
[0027] The present invention advantageously discloses a rear turn signal lamp assembly of a two wheeled vehicle which does not require a plurality of rear turn lamps to be mounted on a rear fender of the two wheeled vehicle, thereby, decreasing load required to be borne by the rear fender due to weight of the plurality of rear turn lamps mounted on the rear fender.
[0028] Apart from the advantages already mentioned, the described invention has several advantages over conventional arrangements prevalent in state of the art. The protected location of the plurality of rear turn lamps shields the plurality of rear turn lamps from direct external impact or crash. This greatly improves the lifetime and reliability of the plurality of rear turn lamps and also raises the impact force value at which the plurality of rear turn lamps tends to fail. At the same time, the left panel member and the right panel member of the two-wheeled vehicle are shaped in such a way as to ensure a wide range of visibility of the plurality of rear turn lamps regardless of their protected and shielded location.
[0029] An embodiment of the present invention is described in further detail in conjunction with the figures in the following description.
[0030] Figure 1 illustrates a left side view of the two wheeled vehicle (100), in accordance with an embodiment of the present subject matter. Typically, a frame assembly (not shown) comprises of a head tube (not shown), a main tube (not shown), and a pair of side tubes (not shown). The head tube (not shown) is disposed towards a front portion. The main tube (not shown) extends downwardly and rearwardly from the head tube (not shown) forming a flat horizontal portion (not shown). The other end of the main tube (not shown) is connected with the pair of side-tubes (not shown) through a bracket member (not shown). The head tube (not shown) is configured to rotatably support a steering tube (not shown) and further connected to the front suspension system (104) at the lower end. A handlebar support member (105) is connected to an upper end of the steering tube (not shown) and supports a handlebar assembly (106).
[0031] Two telescopic suspensions of the front suspension system (104) are attached to a holding member (not shown) on the lower part of the steering tube (not shown) on which is supported the front wheel (109). The upper portion of the front wheel (109) is covered by a front fender (108) mounted to the lower portion of the steering shaft (not shown). The front end of the two wheeled vehicle (100) is protected by a front panel assembly (120). A head lamp assembly (140) is disposed in the front portion with the head lamp (not shown) adapted to be surrounded by the front panel assembly (120).
[0032] A seat assembly (150), on which a rider may sit, is supported on the frame assembly (not shown). Generally, the utility box (not shown) is disposed below the seat (not shown). A coolant tank assembly (not shown) is also disposed below the seat (not shown). A pair of side panel members (130) is mounted on a left side of the two-wheeled vehicle (100) and a right side of the two-wheeled vehicle (100).
[0033] There is front brake (111) and rear brake (not shown) arranged on the front wheel (109) and a rear wheel (110) respectively. The rear wheel (110) is covered by a rear hugger (113) and a rear fender (114) with a turn light (not shown) disposed near it, at the end of the seat assembly (150), on a rear portion (190). The rear wheel (110) is supported towards the rear side of the frame by a horizontally coupled swing arm (180). The swing arm (180) is secured to the rear of the frame assembly (not shown) of the two wheeled vehicle (100) through a rear suspension system (181).
[0034] Figure 2 illustrates a rear view of the two wheeled vehicle (100), in accordance with an embodiment of the present subject matter, particularly showing the pair of side panel members (130) including a left panel member (201) and a right panel member (202). A plurality of turn signal lamps (210) including a left turn signal lamp (221) and a right turn signal lamp (222) are disposed respectively on the left panel member (201) and the right panel member (202).
[0035] As may be seen in the figure, a rear turn signal lamp assembly (250) is disclosed which includes the plurality of turn signal lamps (210) mounted to the pair of side panel members (130). The pair of side panel members (130) is mounted on both sides of the two wheeled vehicle (100). The plurality of turn signal lamps (210) is positioned in such a manner as to be visible to a driver of any automobile trailing the two wheeled vehicle (100).
[0036] The rear wheel (110), the rear wheel hugger (113) and the rear fender (114) are disposed on the rear portion (190) of the two wheeled vehicle (100) as may be seen in the figure.
[0037] Figure 3 illustrates rear view of the two wheeled vehicle (100), in accordance with an embodiment of the present subject matter, particularly showing the sequential LEDs (301). Further, in accordance with the present subject matter (fig. 3a), the power supply (302) is the battery source for the electrical system in the two wheeled vehicle. The switch (303) is the turn indicator switch which sends a signal to the controller (304) that actuates the consecutive LED driver (1 to n) (305) circuitry in a sequential manner with a fixed time delay in a predetermined direction (either 1 to ‘n’ or ‘n’ to 1) which is in turn makes the corresponding LEDs (301) glow or light up in the same predetermined sequence, thereby increasing the accessibility, conspicuity to the viewer as well as unambiguously convey the intent of turn in a more effective manner by attracting attention of the viewer thereby improving safety.
[0038] Figure 4 illustrates a left side perspective view of the rear portion (190) of the two wheeled vehicle (100), in accordance with an embodiment of the present subject matter, particularly showing the left turn signal lamp (221) mounted to the left panel member (201).
[0039] As may be seen in the figure, the plurality of turn signal lamps (210) is disposed on an inner recess (401) each formed by each of the pair of side panel members (130). The inner recess (401) of the pair of side panel members (130) is not exposed to wind, dirt or dust incident on the two-wheeled vehicle (100), when the two wheeled vehicle (100) is in motion.
[0040] In this embodiment, the left panel member (201) and the right panel member (202) are each identically shaped to form a quadrilateral. The left panel member (201) and the right panel member (202) are diagonally mounted to the two-wheeled vehicle (100) in such a manner that one corner (201c, 202c) of the quadrilateral is adapted to form a cantilever end. The disclosed mounting position of the pair of side panel members (130), where the cantilever ends are formed by corners (201c, 202c) of quadrilateral-shaped pair of side panel members (130), allows visibility of the plurality of turn signal lamps (210) housed in the inner recess (401) of the pair of side panel members (130).
[0041] Having the corners (201c, 202c) for the cantilever ends of each of the pair of side panel members (130) ensures that one edge (201e, 202e) each of the quadrilateral-shaped pair of side panel members (130) slopes down towards the respective corners (201c, 202c) forming cantilever ends of the pair of side panel members (130). The sloping down of the edge (201e, 202e) each of the quadrilateral-shaped pair of side panel members (130) ensures a broken line of sight to a driver of an automobile trailing the two-wheeled vehicle (100) from a left side of the rear up to a right side of the rear.
[0042] Therefore, the mounting arrangement of the rear turn signal lamp assembly (250) and shape of the pair of side panel members (130) enables the plurality of turn signal lamps (210) to be seen from all angles from the left side of the rear up to the right side of the rear of the two-wheeled vehicle (100), covering all the angles in between. Thus, the range of angle of visibility of the plurality of turn signal lamps (210) is facilitated, while providing a protected mounting arrangement for the plurality of turn signal lamps (210).
[0043] The rear wheel (110), the rear wheel hugger (113) and the rear fender (114) are disposed on the rear portion (190) of the two-wheeled vehicle (100) as may be seen in the figure.
[0044] Figure 5 illustrates a perspective view of the rear turn signal lamp assembly (250) of the two wheeled vehicle (100), in accordance with an embodiment of the present subject matter. The plurality of turn signal lamps (210) is disposed in an inner recess (401) each on the pair of side panel members (130). The left turn signal lamp (221) is disposed in an inner recess (401a) of the left panel member (201) and the right turn signal lamp (222) is disposed in an inner recess (401b) of the right panel member (202). In this embodiment, 401 includes 401a and 401b.
[0045] As may be seen in the figure, the quadrilateral shape of the pair of side panel members (130) and the manner of mounting in which the cantilever ends of the pair of side panel members (130) are the corners (201c, 202c), the plurality of turn signal lamps (210) are visible from the rear of the two-wheeled vehicle from the left rear side to the right rear side and all the angles between the left rear side and the right rear side. The one edge (201e, 202e) each of the quadrilateral-shaped pair of side panel members (130) which slopes down towards the respective corners (201c, 202c) ensures visibility of the plurality of turn signal lamps (210), including the left turn signal lamp (221) from the left rear side, without the view being obstructed by the left panel member (201) and the right turn signal lamp (222) from the right rear side, without the view being obstructed by the right panel member (202).
[0046] In the present figure, it may be seen that the right turn signal lamp (222) is clearly visible, from the right rear side, without the view being obstructed by the right panel member (202). In the present embodiment, the pair of side panel members (130) are positioned to incline upwards, so as to facilitate better visibility of the plurality of turn signal lamps (210).
[0047] Thus, the present subject matter provides a rear turn signal lamp assembly (250) in which a plurality of turn signal lamps (210) are mounted in an inner recess (401) each of a pair of side panel members (130), the pair of side panel members (130) having a quadrilateral shape each with corners (201c, 202c) forming each cantilever end of the pair of side panel members (130), thereby ensuring a wide range of visibility of the plurality of turn signal lamps (210) while providing greater protection to the plurality of turn signal lamps (210) from exposure to external impact.
[0048] It is to be understood that the aspects of the embodiments are not necessarily limited to the features described herein. Many modifications and variations of the present subject matter are possible in the light of above disclosure. Therefore, within the scope of claims of the present subject matter, the present disclosure may be practiced other than as specifically described.
