FIELD OF INVENTION
The present invention relates to the field of mounting of tires on a vehicle. Preferably, the present invention related to an orientation checking device for a tire (101) of a vehicle.

BACKGROUND OF INVENTION
Tires have lugs or ribs for providing the traction of the vehicle. Lugs are raised portion in tractor tire (101), a gap or rib is a depressed portion between two adjacent lugs. Lugs or ribs also help to channel water from under the tire (101). Lugs give very good traction for off-road vehicles such as farm vehicles and for the drive wheels of trucks and buses. Generally, tires (101) have the lugs with a predefined orientation and therefore, mounting or orientation of the tire (101) becomes important, more specifically tires (101) of off-road vehicles including farm vehicles as the lugs present in the tire (101) provide necessary traction to the vehicle. If the orientation of the tire (101) is not correct, then the ability of the vehicle to pull will be affected. For example, the traction in a tractor tire (101) is provided by lugs. It is observed that when the pair of lugs form a “V” shape when viewed from the back, the orientation is incorrect and when the orientation of tire (101) is such that the pair of lugs form “A” shape when viewed from the back then then orientation of the tire (101) is correct. During assembly due to volume of farm vehicles being assembled it is difficult to manually check the orientation of tire (101) due to limitations of the assembly operator. Hence, there is need to ensure correct orientation of tire (101) before the farm vehicles moves out of the assembly line.

Figure 1 illustrates an orientation checking device for a tire (101) of a vehicle. The device comprises a first elongate member (110) having a profile confirming with a first groove (214) between two adjacent lugs (215A, 215B) of the first set of plurality of lugs (215), and a second elongate member (120) extending at a predefined angle from the first elongate member (110). The second elongate member (120) having a profile confirming to a second groove (224) between two adjacent lugs (225A, 225B) of second set of plurality lugs (225) as illustrated in FIG. 3. An extended portion member (140) extends from an interface (130) between the first elongate member (110) and the second elongate member (120), the extended portion has a profile confirming a gap between an upper lug (215A) of the first set of plurality lugs and an upper lug (225A) of the second set of plurality lugs (225) , and an electronic means (106) in communication with a controller for detecting ingress of checking device in the grooves (214 and 224) of the tire (101) thereby checking the orientation of lugs of the tire (101) on insertion of the device (100) in the grooves (214 and 224).as illustrated in Fig. 1 and Fig. 3 respectively.

In an embodiment the first side of the device has a handle (108) located at the interface (130). The function of the handle is to enable gripping of the device by an operator while check for the orientation of lugs in the tire (101). The predefined angle from the first elongate member (110), the second elongate member (120) depends on the predetermined orientation between the first and second set of the plurality of lugs (215 and 225). The device is suitable for checking the lug orientation of tires (101) of various sizes, for example, particularly between 13.6 to 18.4 centimeter diameter tire (101) can be checked with this device.

Figure 2 illustrates the orientation checking device on a tire (101) of a vehicle representing an incorrect orientation of the tire (101). As shown in Figure 2, the tire (101) has a first set of plurality lugs (215) and a second set of plurality lugs (225) adapted at predefined orientations. The orientation checking device comprises a first elongate member (110) having a profile confirming with a first groove (214) between two adjacent lugs (215A, 215B) of the first set of plurality of lugs. A second elongate member (120) extending at a predefined angle from the first elongate member (110), the second elongate member (120) having a profile confirming to a second groove (224) between two adjacent lugs (225A, 225B) of second set of plurality lugs (225). An extended portion member (140) extending from an interface (130) between the first elongate member (110) and the second elongate member (120), the extended portion having a profile confirming a gap between an upper lug (215A) of the first set of plurality lugs and an upper lug (225A) of the second set of plurality lugs thereby checking orientation of the tire (101) on insertion of the device in the grooves.

The orientation checking device has an electronic means (106) on first surface (107) for detecting ingress of checking device in the grooves of the tire (101). The electronic means may be a sensor. The electronic means (106) comprises a radio frequency identification tag in electronic communication with a controller (115) for receiving information from the electronic means in the form of signal. The device may comprise a display means (112) to display the status of the signal.

The method of checking of orientation with the help of the orientation checking device is explained considering two scenarios. In the tractor manufacturing industry orientation is checked from the back side for rear tires (101). Firstly, when the orientation of rear tire (101) is incorrect. Incorrect orientation of tire (101) happens when the first set of plurality of lugs (215) and second set of plurality of lugs (225) form a “V” shape as shown in Fig. 2 from the rear side of the vehicle. An operator when uses the orientation checking device and aligns the device in a manner such that the first elongate member (110) having a profile confirming with a first groove (214) between two adjacent lugs (115A, 115B) of the first set of plurality of lugs. However, since the profile of the first elongate member (110) does not confirm with the groove (115), the first elongate member (110) is unable to occupy the space created between two adjacent lugs (115A, 115B), hence ingress of the first elongate member (110) does not happen. As the ingress of the first elongate member with respect to the groove (214) created between two adjacent lugs (215A, 215B) does not happen, the electronic means which may comprise a sensor detects this condition and send a signal. The signal may be, for example, a binary signal. Alternately, the electronic means may comprise a radio frequency identification (RFID) tag in electronic communication with a controller (115) for receiving information from said electronic means in the form of signal. This signal is then compared by the controller (115) to check for the status of the orientation checking device (100) with respect to non-ingress of first elongate member (110) with the first groove (214) between two adjacent lugs (115A, 115B) of the first set of plurality of lugs. The status of the signal is then indicated on a display means located on the orientation checking device.

Referring to FIG. 3 shows the orientation checking device on a tire (101) having correct orientation. Correct orientation of tire (101) happens when the first set of plurality of lugs and second set of plurality of lugs of the rear tire (101) form an “A” shape from rear side of the vehicle. To check for the correctness of orientation, an operator places the orientation checking device in a manner such that the first elongate member (110) having a profile confirming with a first groove (214) between two adjacent lugs (215A, 215B) of the first set of plurality of lugs. The profile of the first elongate member (110) confirms with the groove (214), and the first elongate member (110) can occupy the groove (214) created between two adjacent lugs (215A, 215B), hence ingress of the first elongate member (110) takes place. As the ingress of the first elongate member (110) with respect to the space created between two adjacent lugs (215A, 215B) takes place, the electronic means which may comprise a sensor (106) detects this condition in the form of a signal. The signal may be, for example, a binary signal. Similarly, the ingress of the second elongate member (120) with respect to the groove (224) created between two adjacent lugs (225A, 225B) is completed, as the profile of the second elongate member (120) matches with the groove (224). The electronic means may comprise a radio frequency identification (RFID) tag in electronic communication with a controller (115) for receiving information from said electronic means in the form of signal. This signal is then compared by a controller (115) to check for the status of the orientation checking device (100) with respect to ingress of first elongate member (110) with a first groove (214) between two adjacent lugs (115A, 115B) of the first set of plurality of lugs. The status of the signal is then indicated on a display means located on the orientation checking device. The operator thus gets an indication that the profile of the lugs (215 and 225) is correct and can proceed for further assembly operations.
Figure 4 illustrates a method for checking the orientation of lugs in a tire (101) of a vehicle by an orientation checking device. The method comprises the following steps, placing at step 400 a first elongate member (110) of the orientation checking device (100) between a first groove (214) of two adjacent lugs (215A, 215B) of first set of plurality of lugs (215), and a second elongate member (120) between second groove (224) of two adjacent lugs (225A, 225B) of second set of plurality lugs. Detecting, at step 402, by an electronic means, ingress of the first elongate member (110) and the second elongate member (120) with respect to the grooves (214 and 224). Receiving, at step (404), by a controller, status of the detection from the electronic means in the form of a signal. Comparing, at step (406), by the controller, the received signal with respect to a predefined value for checking the orientation of lugs in the tire (101) of the vehicle and communicating at step (408) by the controller, magnitude of the signal to a display means located on the orientation checking device (100). The predefined value is function of orientation between the first set of plurality lugs (215) and the second set of plurality lugs (225).
During working to check the orientation of the lugs (215 and 225) of the tire (101) a user places (400) the orientation checking device (100) on the tire (101) from the rear side of the vehicle in a manner such that the first elongate member (110) of the orientation checking device (100) is confirms with the first groove (214) of two adjacent lugs (215A, 215B) of first set of plurality of lugs (215), and a second elongate member (120) between second groove (224) of the two adjacent lugs (225A, 225B) of second set of plurality lugs. The user may use a handle (108) located on the orientation checking device (100). The electronic means then detects (402), the ingress of the first elongate member (110) and said second elongate member (120) with respect to the grooves (214 and 224). The status of detection is then received (404) by the controller in the from of a signal. The controller then compares (406) the signal with respect to a predefined value for checking the orientation of lugs in the tire (101) of the vehicle. For example, the predefined value can be 1 for detecting correct orientation of lugs as illustrated in the detailed description of FIG. 3 or the predefined value can be 0 for detecting incorrect orientation of lugs as illustrated in the detailed description of FIG. 2. The controller then communicates (408) this predefined value to a display means located on said orientation checking device (100). In case of incorrect orientation, the user can take appropriate action of changing the position of the tire (101) so the orientation of lugs is correct. By this method and use of the device it is now possible to avoid incorrect orientation of lugs (215 and 225) in the vehicle.

Advantages:
1. The proposed orientation checking device helps in detecting the correct orientation of tire (101) in a farm vehicle.
2. The proposed orientation checking device gives an alert to a user about the correct orientation of tire (101) in a farm vehicle.
