[0019] Referring Figures 1-3, illustrates an adjustable device (100) for a vehicle according to an exemplary embodiment. Referring Figure 1 illustrates an isometric view of the adjustable device (100) according to an aspect of the present invention. The adjustable device (100) comprises a hydraulic jack (110) for enabling lifting/lowering of a component, preferably a transmission system while decking / un decking /assembling / dis assembling the transmission system on to the vehicle. The hydraulic jack (110) comprises an integral vertically extending member (112); a first supporting member / resting member (115) circumscribing an outer surface of the hydraulic jack (110) at a top end at a desired height and a base support member (116) at a bottom end of the hydraulic jack (110). Thus, the hydraulic jack (110) is mounted on the base support member (116). According to an embodiment, the base support member (116) is welded to the hydraulic jack (110). The base support member (116) according to an embodiment has plurality of outwardly extending fingers to which a plurality of adjustable rolling wheels (118) are coupled for enabling easy movement of the adjustable device (100) to any desired location. The plurality of adjustable rolling wheels (118) are removably coupled to the plurality of outwardly extending fingers of the base support member (116) using known mechanisms not limited to a bolt and nut, screw arrangements, and snap fit arrangements. The base support member (116) accordingly may include any number of fingers as per requirement and not limited to thereof four fingers. The plurality of adjustable rolling wheels (118) also have provision for locking thereby providing stability and firmness while in rest position. During operation, said movement of the plurality of adjustable rolling wheels (118) and movement of base support member (116) is restricted/locked by a rotational translation of a lever. According to the embodiment, an adjustable first lever (120) is configured to the hydraulic jack (110) at bottom end. The rotation of the adjustable first lever (120) translates into vertical extending / retracting of said vertically extending member (112) along a central axis (Y-Y), thereby enabling lifting/lowering of the hydraulic jack (100) and adjusting a desired height of said hydraulic jack (110).
[0020] Referring Figure 2 illustrates an exploded view of the adjustable device (100). According to the embodiment, the integral vertically extending member (112) has a top end and a bottom end. A bottom end of the integral vertically extending member (112) is located within the hydraulic jack (110) and a top end of the integral vertically extending member (112) has a cut-out for enabling coupling of the integral vertically extending member (112) with a horizontal member (130), when a locking member (125) is inserted through the cut-out of the integral vertically extending member (112) and passes through a plurality of colinear holes provided within a plurality of bottom connecting plates (122) at a bottom surface of the horizontal member (130), thus mounting of the horizontal member (130) onto the hydraulic jack (110) via the integral vertically extending member (112) is made possible for locating a component of the vehicle safely for example a transmission system. According to an embodiment, the locking member (125) is a bolt and nut arrangement, however the integral vertical extending member and the horizontal member (130) may be interconnected by other type of locking mechanisms. According to the embodiment, the horizontal member (130) includes a plurality of support members (135) on a top surface. In the embodiment, each support member (135) has a “U” shaped configuration recessing from a top surface complimentary to a bottom surface of the transmission system intended for decking / un decking /assembling / dis assembling to be directly mounted on the plurality of support members (135). However, each support member (135) may be of other configurations as per requirement.
[0021] Referring Figure 3, illustrates a detailed view of the adjustable device (100). Referring figures 1-3, a first support member (135a) is located at a greater distance “A” from the central axis (Y-Y) and a second support member (135b) is located at a shorter distance A’ from the central axis (Y-Y), said distance of the first support member (135a) is greater than the distance of the second support member (135b) from the central axis (Y-Y). According to an embodiment, the plurality of bottom connecting plates (122) of the horizontal member (130) are located equidistantly left-right from the central axis (Y-Y). In an embodiment, the support members (135) and the plurality of bottom connecting plates (122) are welded to the horizontal member (130). According to an embodiment, the adjusting device (100) and the horizontal member (130) has at least one degree of freedom in at least one axis. The adjusting device (100) is adjustable vertically along the axis Y-Y and the horizontal member (130) is titled about a point co-axial to the locking member (125). According to the embodiment, a coupling arrangement (140) is configured to said integral vertically extending member (112) for enabling tiling of the horizontal member (130) in at least a degree of freedom about a central axis (co-axial) of the locking member (125), thereby enabling ease alignment of transmission with engine. The horizontal member (130) is tilted by the coupling arrangement (140) with a maximum angle of titling of the horizontal member (130) about 20~25 degree in a clockwise and anticlockwise direction. According to the embodiment, the horizontal member (130) may be tilted using an adjustable second lever (150). The rotation of the adjustable second lever (150) translates into angular movement of the horizontal member (130). Thus, the adjustable first and second levers (120, 150) enables the horizontal member (130) to achieve any desirable height and angle thereby providing alignment of the components with the vehicle. The horizontal member (130) ensures no falling of transmission during any of the moment of operation. Further proper alignment of the transmission with engine is also achieved with the titling of the horizontal member (130) as per requirement. The tilting of the horizontal member (130) is made possible with the coupling arrangement (140). According to the embodiment, the coupling arrangement (140) comprises a first coupling member (142), an intermediate member (145), and a second coupling member (146) integrally, welded to each other. The intermediate member (145) is of a triangular shape that is configured to provide good support and interconnects the first coupling member (142) and the second coupling member (146). The second coupling member (146) engages the integral vertically extending member (112) and the adjustable second lever (150) is located within the first coupling member (142). The first coupling member (142) is provided with a second supporting member / resting member (155), which also aids as a safety member and supports the tilting operation of the horizontal member (130). The first coupling member (142) is located at a greater height than the height of the second coupling member (146) so that the second support supporting member / resting member (155), is constantly in contact with the horizontal member (130) for supporting tilting operation of the horizontal member (130).
[0022] According to the embodiment, the coupling arrangement (140) may be integrally welded or may be removably coupled to the integral vertically extending member (112). According to the embodiment, the adjustable second lever (150) is a screw type lever. The adjustable device (100) is easy to operate with less human skill. With the adjustable device (100) any transmission may be fixed with engine with less effort and safety. The adjustable device (100) is portable to use at any premises, on/off a production location to carry out operations.
[0023] Conventionally, (un) decking of transmission carried out by manually, requires high effort and human intervene, and is not at all safe due to manual lifting /taking down transmission (heavy component weight). There is a high chance of injury if transmission falls during lifting or taking down at vehicle level. With the teachings of the present adjustable device (100) the effort of lifting/lowering and alignment of the transmission system with the engine is reduced drastically and assembly/disassembly operation may be carried out on short period of time. The adjustable device (100) may be operated by less skilled operator and widely adaptable at an off-production location/after-market/dealer end/proto build shop. Further, accurate and efficient alignment of the transmission system with the engine is made possible.
[0024] According to an embodiment, the operation of adjusting the height of the hydraulic jack (110), tilting of the horizontal member may controlled using a controller with necessary electrical connections and known devices like processors, circuits, relay connections etc. Thus, providing the provision alignment of the transmission system automatically with required sensors and other suitable devices known in the art.
