Detailed description of the embodiments:
[0011] Fig. 1 illustrates a load carrier for a vehicle, according to an embodiment of the present invention. The load carrier 110 comprises a platform 124 to hold a load, characterized by, the load carrier 110 capable of being mounted on a chassis frame 104 of the vehicle 100 in a removable manner. The vehicle 100 is preferably a transport vehicle 100 such as Light Commercial Vehicle (LCV), lorry, however not restricted to the same. Further, the vehicle 100 is either a hybrid, combustion engine based or pure electric.
[0012] In an embodiment, the platform 124 of the load carrier 110 is a base of a container 114. The container 114 is any one of open type and closed type. Further, the load carrier 110 comprises at least two wheels fixed to the platform 124. In the present invention, two sets of wheels are provided, a first wheel set 106 and a second wheel set 108, each having two wheels. The wheels are capable of being held in working position and a retracted position. In a first view 120, the load carrier 110 is shown dismounted/detached or disassembled from the vehicle 100 or in a ready to be assembled position. A bidirectional arrow shows a direction of assembling and disassembling the load carrier 110 with the vehicle 100. The load carrier 110 is aligned with the longitudinal direction of the vehicle 100. In the second view 130, the load carrier 110 is assembled on to the chassis frame 104 of the vehicle 100. A third view 140 illustrates the bottom of the load carrier 110, where the structure of the platform 124 is visible.
[0013] In the present invention, a track width represents the distance between the two wheels on the same axis. Therefore, the track width of the first wheel set 106 is wider than the vehicle width, and the track width of the second wheel set 108 is less than or within the vehicle width. The wider track width of the first wheel set 106 enables to move the entire load carrier 110 over the chassis frame 104, until a cabin (driver seating area) of the vehicle 100 reached or till the end position.
[0014] According to an embodiment of the present invention, the load carrier 110 is mounted on the chassis frame 104 through engagement between respective set of first guide member and set of second guide member. The set of first guide member and the set of second guide member are selected from a group comprising a combination of sliding rails 102, and a combination of sliding rail 102 and rollers 112. For example, in a first combination, the first guide member comprises a single rail 102 and the second guide member comprises rollers 112. The rollers 112 roll on the rail 102 and allow mounting of the load carrier 110. Alternatively, in the second combination, the first guide member comprises the rollers 112 and the second guide member comprises the single rail 102. In the second combination, the rail 102 slides over the rollers 112 during mounting and dismounting of the load carrier 110. In another combination, two parallel sliding rails 102 are provided in the first guide member and rollers 112 are provided in the second guide member or vice-versa. In yet another combination, the first guide member is at least one hollow sliding rail 102 and the second guide member is a complimentary sliding rail 102, thus no rollers 112 are used.
[0015] A method of assembling the load carrier 110 on to the chassis frame 104 is provided. At first, the load carrier 110 is assumed to be resting on the first wheel set 106 and the second wheel set 108. The load carrier 110 is either filled with the goods or is empty. An operator manually pushes the load carrier 110 and aligns in longitudinal direction of the chassis frame 104 of the vehicle 100, which is provided at the rear of the vehicle 100. The operator pushes and brings the load carrier 110 over the chassis frame 104, resulting in the engagement of the first guide member and the second guide member. The operator pushes until the end of the cabin is reached. Once the load carrier 110 is completely above the chassis frame 104, the operator locks the load carrier 110, thereby arresting any movement during travel of the vehicle 100. The first wheel set 106 and the second wheel set 108 are still in contact with the ground, which now needs to be retracted. The operator then manually or electronically retracts the same.
[0016] A method of disassembling the load carrier 110 from the chassis frame 104 is provided. The method comprises setting the first wheel set 106 and the second wheel set 108 to working position, i.e. open condition and making contact with ground. Next, the load carrier 110 is unlocked, and then the operator pulls the load carrier 110 and out of the chassis frame 104 in a sliding manner. The setting of the first wheel set 106 and the second wheel set 108 to working position is either manual or electronic or combined.
[0017] Fig. 2 illustrates an assembled load carrier on the vehicle, according to an embodiment of the present invention. In continuation of the Fig. 1, in a fourth view 210, a side of the vehicle 100 is shown with the load carrier 110 mounted on the chassis frame 104. The side view clearly illustrates the first wheel set 106 and the second wheel set 108 are in contact with the ground after the assembly or before the disassembly.
[0018] As mentioned before, the load carrier 110 is a base of the container 114 or just a platform 124. The container 114 is any one of the open type and the closed type. The load carrier 110 comprises at least two wheels. The wheels are capable of being held in working position and a retracted position. In the fourth view 210, the wheels are shown in working position. [0019] In the fifth view 220, the first wheel set 106 and the second wheel set 108 are retracted to closed position. Both of the first wheel set 106 and the second wheel set 108 are moved inside the body of the vehicle 100. The mechanism of retraction is explained in Fig. 5 and Fig. 6.
[0020] According to an embodiment of the present invention, the vehicle 100 is provided with the load carrier 110 and the chassis frame 104. The load carrier 110 is mounted on the chassis frame 104 of the vehicle 100 to carry load. The vehicle 100 is characterized by, the load carrier 110 being mounted in a removable manner. To enable the removable feature, the load carrier 110 comprises the set of first guide member and the chassis frame 104 comprises a set of second guide member. As described above, the set of first guide member and the set of second guide member are selected from a group comprising a combination of sliding rails 102, and a combination of sliding rail 102 and roller 112. The vehicle 100 is also provided with a space 122 for storing the retracted first wheel set 106. In the fourth view 210 the space 122 is open, whereas in the fifth view 220, the space 122 is closed. The space 122 is closed by a door of a sliding type or hinged type.
[0021] Fig. 3 illustrates different views of the load carrier, according to an embodiment of the present invention. A first side view 310 shows the load carrier 110 with working position of the first wheel set 106 and the second wheel set 108. A second side view 320 shows the load carrier 110 with retracted/closed position of the first wheel set 106 and the second wheel set 108. A first rear view 330 shows the load carrier 110 with working position of the first wheel set 106 and the second wheel set 108. The first wheel set 106 which are towards front of the chassis frame 104 is clearly visible to have wider track width than that of the second wheel set 108. A second rear view 340 shows load carrier 110 with closed position of the first wheel set 106 and the second wheel set 108.
[0022] A first perspective view 350 shows the load carrier 110 in working position of the first wheel set 106 and the second wheel set 108. A second perspective view 360 shows the load carrier 110 in retracted position of the first wheel set 106 and the second wheel set 108.

The chassis frame 104 is provided with two sliding rails 102, however the chassis frame 104 is possible to be provided with at least one sliding rail 102. Thus, not only one, but two or more parallel sliding rails 102 are possible. The wheels in the chassis frame 104 are shown for simplicity of understanding, and do not form the part of the chassis frame 104.
[0025] Below the chassis frame 104, the vehicle 100 fit with the same chassis frame 104 is illustrated.
[0026] Fig. 5 illustrates a drive mechanism of a first wheel set, according to an embodiment of the present invention. The drive mechanism is referred to as first drive 116. The first drive 116 comprises a first pinion 502 in meshing engagement with two toothed racks 504, each connected to respective vertical bars 506. The racks 504 are parallel to the chassis frame 104, whereas the vertical bars 506 are perpendicular to the chassis frame 104. Also, the first wheel set 106 are connected to the vertical bars 506 in pivoting and rotatable manner. [0027] Considering the first pinion 502 at the center, the racks 504 are movable sideways. The racks 504 engage with the first pinion 502 together but in opposite sides. In a sixth view 510, the racks 504 are shown in the extreme side position, along with the first wheel set 106 in the working or lowermost position, i.e. making contact with ground. This is the position when either the load carrier 110 has moved to the extreme end of the chassis frame 104 while mounting or the load carrier 110 is being removed from the chassis frame 104. The movement of the vertical bars 506 in up and down direction is performed as known in the art, i.e. either manually or motor assisted. Once the vertical bars 506 are moved to the uppermost position, the first wheel set 106 is moved inside within the body of the vehicle 100 by the rotation of the first pinion 502 in one direction. The rotation is done through manually or through a motor.
[0028] If the first wheel set 106 is required to be moved out for removal of the load carrier 110, then the first pinion 502 is rotated in opposite direction. The rotation of the first pinion 502 is either manual or motorized. The seventh view 520 illustrates the retracted position of the first wheel set 106.
[0029] Fig. 6 illustrates a drive mechanism for a second wheel set of the load carrier, according to an embodiment of the present invention. The drive mechanism is referred to as second drive 118. The second drive 118 comprises a second pinion 602 provided on a horizontal shaft 604. The shaft 604 in connected to the second wheel set 108 through foldable/kinematic linkages 606. The foldable linkages 606 are optionally supported by hydraulic cylinders (not shown). In other words, the retraction is performed by the hydraulic cylinders such as a gas-spring/balancer. The end of the foldable linkages 606 is where the second wheel set 108 are mounted.
[0030] In the eighth view 610, the second wheel set 108 is shown in the working position, whereas in the ninth view 620, the second drive 118 is shown in the retracted position. The retracted position is achieved by the rotation of the second pinion 602. Again, the rotation of the second pinion 602 is possible either manually or electronically by the use of a motor 608.
[0031] According to another embodiment, a mounting assembly of the load carrier 110 on the chassis frame 104 of the vehicle 100 is provided. The assembly comprises, the set of first guide member provided on the chassis frame 104 of the vehicle 100, and the set of second guide member provided on the load carrier 110. The load carrier 110 positioned on the chassis frame 104 through the engagement between the set of second guide member and the set of first guide member. The load carrier 110 being positioned in a removable manner.
[0032] According to the present invention, the vehicle 100 with the chassis frame 104 integrated with rail 102 and modular load carrier 110 is provided. The load carrier 110 is fit with four wheels of chassis frame 104. The load carrier 110 is positioned on the rail 102 through a handle. When need to move the load carrier 110, the first wheel set 106 and the second wheel set 108 are set to working position, supported by the kinematic links. The load carrier 110 is then pulled out through rails 102 on chassis frame 104. The first drive 116 and the second drive 118 are welded/fastened to the platform 124 of the load carrier 110. The first wheel set 106 and the second wheel set 108 are mounted with the strut assembly to absorb the vibrations from ground.
[0033] According to an embodiment of the present invention, a modular mobile load carrier 110 with kinematic wheel arrangement and guide rail 102 in the vehicle 100 is provided. The present invention is applicable for an electric vehicle 100, a hybrid vehicle 100 and the combustion engine vehicle 100. The modular load carrier 110 has feasibility to detach and transport to a bay area without the vehicle 100 itself. The modular load carrier 110 acts as medium to transport goods of wide variety is sizes. Also the load carrier 110 of different volumes and sizes are possible. The load carrier 110 is usable on its own without the need for attaching to the vehicle 100.
