Further, it will be apparent to a person skilled in the art that the shape and size of the handle 146 may be such that the user may conveniently grip the backpack support member 140 via the handles 146.

The backpack support member 140 may include at least one elastic element based pin 148 at an upper portion of the backpack support member 140. Specifically, the elastic element based pin 148 may be provided on the front side 142 of the backpack support member 140. In a preferred embodiment, the backpack support member 140 may include two widely spaced elastic element based pins 148 at the upper portion of the backpack support member 140. Referring now to Fig. 7, a perspective view of the elastic element based pin 148 is illustrated, in accordance with an exemplary embodiment of the present invention. The elastic element based pin 148 may have an attaching end 150, a hook end 152 and a bridge 154. The bridge 154 may connect the attaching end 150 and the hook end 152. The elastic element based pin 148 may be attached to the backpack support member 140 via the attaching end 150. In an embodiment, the tip of the hook end 152 may be offset from the center. Such arrangement of the hook end 152 may make it easier for the elastic element based pin 148 to engage the cut-through hole 110. The elastic element based pin 148 may be movable between a locked position and an unlocked position. To explain clearly, the elastic element based pin 148 may be movable in a linear motion between an upper position and a lower position. When the elastic element based pin 148 is at the upper position, the elastic element based pin 148 is in a locked position, and when the elastic element based pin 148 is at the lower position, the elastic element based pin 148 is in the unlocked position. The elastic element based pin 148 may include an elastic element (not shown in the figures) to move the elastic element based pin 148 from the unlocked position to the locked position. Specifically, the elastic element may reposition the elastic element based pin 148 at the locked position whenever it is moved to the unlocked position.

The elastic element based pin 148 may be arranged on the backpack support member 140 in such a manner that while mounting the backpack support member 140 on the back support member 102, the elastic element based pin 148 may engage the cut-through hole 110 of the back support member 102. Similarly, in embodiment where the backpack support member 140 includes two elastic element based pins 148 and back support member includes two cut-through holes 110, each of the elastic element based pins 148 may engage the respective cut-through hole 110.

When the elastic element based pin 148 is mounted on the cut-through hole 110, the hook end 152 of the elastic element based pin 148 may be engaged in the cut-through hole 110, and the bridge 154 may lie in the cut section 116 of the cut-through hole 110. Such an arrangement may enable the cut-through 110 to restrict the sidewise movement of the elastic element based pin 148, and may allow the linear movement of the elastic element based pin 148 through the cut section 116 while moving between the locked position and the unlocked position.

The backpack support member 140 may further include at least one clamp 156 at a lower portion of the backpack support member 140. Specifically, the clamp 156 may be provided at the front side 142 of the backpack support member 140. In a preferred embodiment, the backpack support member 140 may include two widely spaced clamps 156 at the lower portion of the backpack support member 140. In an embodiment, the clamp 156 may be a projection extending from the lower portion of the back pack support member 140. The arrangement of the clamp 156 may be in such a manner that while mounting the backpack support member 140 on the back support member 102, the clamp 156 may be supported on the clamp support 118. Similarly, in embodiment where the back support member 102 includes two clamp supports 118 and the backpack support member 140 includes two clamps 156, each of the clamps 156 may rest on the respective clamp support 118. It will be apparent to a person skilled in the art that the clamp 156 and the clamp support 118 may prevent the vertical downward movement of the backpack support member 140 when the backpack support member 140 is mounted on the back support member 102.

The backpack support member 140 may further include an elastically loaded switch 158. Referring now to fig. 8, a perspective view of the elastically loaded switch 158 is illustrated, in accordance with an exemplary embodiment of the present invention. The elastically loaded switch 158 may be provided at the front side 142 of the backpack support member 140. Further, the elastically loaded switch 158 may be arranged between the upper portion and the lower portion of the backpack support member 140. The elastically loaded switch 158 may include a slanting surface 160, where the top end of the slanting surface 160 may project outwards. It should be noted that due to an elastic arrangement within the elastically loaded switch 158, the elastically loaded switch 158 could be pressed inward easily by applying force on the slanting surface 160. Similarly, on removing the force, the elastically loaded switch 158 may return back to its default state where the top end of the slanting surface 160 may project outward. The elastically loaded switch 158 may be arranged to slide in a linear slot 162 provided on the backpack support member 140. The elastically loaded switch 158 may be movable between a locked position and an unlocked position within the slot 162. For the purpose of explanation, when the elastically loaded switch 158 is at the upper position of the slot, the elastically loaded switch 158 may be in the locked position. Alternatively, when the elastically loaded switch 158 moves to the lower position of the slot 162, the elastically loaded switch 158 may move to the unlocked position.

The elastically loaded switch 158 may be configured to engage the elastic element based sliding member 122 when the backpack support member 140 is mounted on the back support member 102. Therefore, when the elastic element based sliding member 122 may move between the locked position and the unlocked position, the elastically loaded switch 158 may move along with the elastic element based sliding member 122. In other words, the movement of the elastically loaded switch 158 may be synchronous with the movement of the elastic element based sliding member 122.

The elastically loaded switch 158 may be connected to the elastic element based pin 148 of the back support member 140. In an embodiment having two elastic element based pins 148, the elastically loaded switch 158 may be mutually connected to both the elastic element based pins 148. The elastically loaded switch 158 may be connected to the elastic element based pin 148 via at least one of a wire, cord, fabric strip or any type of push and/or pull means. For the purpose of illustration, it is shown in the fig. 5 that the elastically loaded switch 158 is connected to the elastic element based pin 148 with a cord 164. As the elastically loaded switch 158 may be connected to the elastic element based pin 148, the movement of the elastic element based pin 148 may be synchronous to the movement of the elastically loaded switch 158.

The backpack support member 140 may further include a flange 166. The flange 166 may be provided on the front side 142 of the backpack support member 140. Specifically, the flange 166 may be provided between the upper portion and the lower portion of the backpack support member 140. For the purpose of explanation, the flange 166 may be provided at the position corresponding to the position of the auxiliary elastically loaded switch 136 on the back support member 102. The auxiliary elastically loaded switch 136 may accommodate the flange 166 when the backpack support member 140 is mounted on the back support member 102. The auxiliary elastically loaded switch 136 and the flange 166 may restrict the upper movement of the backpack support member 140.

The system 100 may further include a pull-cord 168 (shown in fig. 2). The pull-cord 168 may be connected to the lower end 126 of the elastic element based sliding member 122. The pull-cord 168 may be at least one of a wire, cord, strip etc. In certain embodiments, the pull-cord 168 may have gripping end to properly hold the pull-cord 168. The pull-cord 168 may be pulled manually by the user when the backpack support member 140 is to be dismounted from the back support member 102. In other words, the user may pull the pull-cord 168 when the backpack is to be unloaded from the back of the user. As the pull-cord 168 is connected to the elastic element based sliding member 122, the pull-cord 168 may cause the elastic element based sliding member 122 to move from the locked position to the unlocked position whenever the pull-cord 168 is pulled by the user. Fig. 9 illustrates a perspective view of the system 100 for loading and unloading the backpack, in accordance with an exemplary embodiment of the present invention.

According to another exemplary embodiment of the present invention, a method 200 for loading and unloading a backpack is disclosed. The method 200 for loading the backpack may include a step 202 of wearing a back support member on the back of a user. According to an embodiment, the back support member may be worn via a wearable jacket attached to the back support member. According to another embodiment, the back support member may be worn via at least one strap attached to the back support member. The back support member may include at least one cut-through hole at an upper portion of the back support member. The back support member may further include at least one clamp support at a lower portion of the back support member. The back support member may further include an elastic element based sliding member guided to slide in a guide path between a locked position and an unlocked position. The back support member may further include an auxiliary elastically loaded switch in-between the upper portion and the lower portion of the back support member.

The method 200 for loading the backpack may further include a step 204 of mounting a backpack support member on the back support member. The backpack support member may carry the backpack on it. In other words, the backpack may be attached to the backpack support member. The backpack support member may include at least one elastic element based pin at an upper portion of the backpack support member. The elastic element based pin may be movable between a locked position and an unlocked position. The elastic element based pin may be configured to engage the cut-through hole. The backpack support member may further include at least one clamp at a lower portion of the backpack support member. The clamp is configured to rest on the clamp support. The backpack support member may further include an elastically loaded switch configured to engage the elastic element based sliding member. The elastically loaded switch is mutually connected to the elastic element based pin, and is movable between a locked position and an unlocked position. The backpack support member may further include a flange that is accommodated in the auxiliary elastically loaded switch.

Initially, the elastic element based sliding member, the elastic element based pin and the elastically loaded switch may be in the default locked position. When the backpack support member is mounted on the back support member, the elastic element based pin of the backpack support member may engage the cut-through hole of the back support member. In an embodiment having two or more elastic element based pins and cut-through holes, each elastic element based pin may engage the respective cut-through hole. Further, in the mounted position, the cut-through hole may restrict the sidewise movement of the elastic element based pin. In a default state, the elastic element based pin may be positioned in a locked position.

Moreover, when the backpack support member is mounted on the back support member, the clamp of the backpack support member is supported on the clamp support of the back support member. In an embodiment having two or more clamps and clamp supports, each clamp may be supported on the respective clamp support. The clamp and the clamp support may restrict the vertical downward movement of the backpack support member.

Furthermore, in the mounted position, the elastically loaded switch of the backpack support member is engaged to the elastic element based sliding member of the back support member. In the default state, both the elastically loaded switch and the elastic element based sliding member may be in the locked position. When the backpack support member is mounted on the back support member, the elastically loaded switch may restrict the upward movement of the backpack support member. The elastically loaded switch may be further connected to the elastic element based pin. Therefore, the movement of the elastically loaded switch may cause the movement of the elastic element based pin between the locked position and the unlocked position.

The method for unloading the backpack may include a step 206 of dismounting the backpack support member from the back support member by pulling a pull-cord. The pull-cord may be connected to the elastic element based sliding member. The pull-cord may be manually pulled by the user to unload the backpack.

For dismounting the backpack support member from the back support member, the user may pull the pull-cord in a single action. As the pull-cord may be connected to the elastic element based sliding member, the elastic element based sliding member may move from the default locked position to the unlocked position. As the elastically loaded switch may be engaged to the elastic element based sliding member, the movement of the elastic element based sliding member may cause the elastically loaded switch to move from the default locked position to the unlocked position. As explained above, the elastic element based pin may be connected to the elastically loaded switch. Therefore, the movement of the elastically loaded switch may cause the movement of the elastic element based pin from the default locked position to the unlocked position. While moving from the locked position to the unlocked position, the elastic element based pin may move through the cut section of the cut-through hole. As soon as the elastic element based pin may move to the unlocked position, the backpack support member may dismount from the back support member. In other words, the backpack may get unloaded from the back of the user.

Once the pull-cord is released, due to the elastic element, the elastic element based sliding member may move to its default locked position. Similarly, the elastically loaded switch and the elastic element based pins may also move to their respective default locked position.
