DETAILED DESCRIPTION OF THE INVENTION:

[0017] Reference will now be made in detail to the description of the present subject matter, one or more examples of which are shown in figures. Each example is provided to explain the subject matter and not a limitation. Various changes and modifications obvious to one skilled in the art to which the invention pertains are deemed to be within the spirit, scope and contemplation of the invention.

[0018] The present invention provides an assembly for securing a gear-box using a spring-loaded lock pin wherein the gear-box is secured with a ferrule by means of a spring-loaded lock pin which enables lock and unlock of the ferrule through a ‘press and release’ mechanism. The spring-loaded lock pin comprises an internal keyway for facilitating anti-rotational movement of the spring-loaded lock pin and a slot recess for enabling hassle-free lock and unlock between the ferrule and the gear-box. Further, an external keyway provided in the gear-box mates with the internal keyway etched in the spring-loaded lock pin for facilitating anti-rotational movement of the spring-loaded lock pin under locked and unlocked condition of the ferrule.

[0019] FIG. 1 illustrates an assembly for securing a gear-box using a spring-loaded lock pin. The assembly (100) comprises a gear-box (101) for enabling variable vehicle speed and torque, wherein the gear-box (101) comprises an external keyway (102) for facilitating anti-rotational movement under locked and unlocked condition of the gear-box (101). A ferrule (103) is inserted into the gear box (101), wherein the ferrule (103) comprises a circular recess (104) for securing the position of ferrule (103) within the gear-box (101). The gear-box (101) and the ferrule (103) are removably secured using a spring-loaded lock pin (105). The spring-loaded lock pin (105) enables lock and unlock of the ferrule (103) by means of a ‘press and release’ mechanism.

[0020] The spring-loaded lock pin (105) comprises an internal keyway (106), a slot recess (107) and a projection (108). The internal keyway (106) is etched in the spring-loaded lock pin (105) for facilitating anti-rotational movement of the spring-loaded lock pin (105) under locked and unlocked condition of the gear-box (101). The spring-loaded lock pin (105) is removably slided into the gear-box (101) such that the external keyway (102) of the gear-box (101) mates with the internal keyway (106) etched in the spring-loaded lock pin (105) for facilitating anti-rotational movement of the spring-loaded lock pin (105) under locked and unlocked condition of the ferrule (103) and the gear-box (101). The slot recess (107) is etched on one side of the spring-loaded lock pin (105) for enabling hassle-free lock and unlock between the ferrule (103) and the gear-box (101). Upon being pressed, the spring-loaded lock pin (105) releases the ferrule (103) from the gear-box (101) into the slot (107) to enable free movement of the ferrule (103) under unlocked condition.

[0021] Further, the assembly (100) comprises a bellow (109) and an o-ring (110) which are disposed on opposite sides of the spring-loaded lock pin (105). The bellow (109) protects the spring-loaded lock pin (105) from external dust on the side in which it is disposed and the o-ring (110) disposed on the side opposite to the bellow (109), protects the spring-loaded lock pin (105) from external dust on the side in which it is disposed. Further, the assembly (100) comprises a washer (111) to enable proportional load distribution of the spring-loaded lock pin (105).

[0022] The washer (111) prevents the occurrence of damages to the o-ring (110) caused due to the constant force exerted by the spring-loaded lock pin (105). The washer (111) and a circlip (112) are employed for maintaining the position of the spring-loaded lock pin (105) under locked condition of the gear-box (101) and ferrule (103).

[0023] FIG. 2 illustrates a gear-box with spring-loaded lock pin under locked condition of the gear box. The slot recess (107) provided on the spring-loaded lock pin (105) enables hassle-free lock and unlock between the ferrule (103) and the gear-box (101). The projection (108) of the spring-loaded lock pin (105) indicates locked condition between the ferrule (103) and gear-box (101).

[0024] FIG. 3 illustrates an exploded view of the spring-loaded lock pin with an internal keyway and slot recess to facilitate anti-rotational movement of the spring-loaded lock pin. The internal keyway (106) facilitates anti-rotational movement of the spring-loaded lock pin (105) under locked and unlocked condition of the gear-box (101). The slot recess (107) provided on the spring-loaded lock pin (105) enables hassle-free lock and unlock between the ferrule (103) and the gear-box (101).

[0025] FIG. 4 illustrates a side-view of the gear box with an external keyway to facilitate anti-rotational movement of the spring-loaded lock pin. The gear-box (101) comprises an external keyway (102) for facilitating anti-rotational movement under locked and unlocked condition of the gear-box (101). The external keyway (102) of the gear-box (101) mates with the internal keyway (106) etched in the spring-loaded lock pin (105) for facilitating anti-rotational movement of the spring-loaded lock pin (105) under locked and unlocked condition of the ferrule (103) and the gear-box (101).

[0026] FIG. 5 illustrates a perspective view of the ferrule with a circular recess for securing the position of the ferrule within the gear-box. The circular recess (104) secures the position of ferrule (103) within the gear-box (101). Further, the assembly (100) enables a simple ‘press and release’ mechanism, wherein upon being pressed, the spring-loaded lock pin (105) releases the ferrule (103) from the gear-box (101) into the slot recess (107) to enable free movement of the ferrule (103) under unlocked condition. Therefore, the present invention provides a hassle-free mechanism for locking or unlocking a gear box by employing a minimum number of components.

[0027] The present invention provides an assembly for securing a gear-box (101) using a spring-loaded lock pin (105). The internal keyway (106) etched in the spring-loaded lock pin (105) facilitates anti-rotational movement of the spring-loaded lock pin (105) under locked and unlocked condition of the gear-box (101). Further, the ‘press and release’ mechanism adapted by the present invention ensures a simple and secure engagement between the ferrule (103) and gear box (101).

[0028] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist.
