Description

BACKGROUND OF THE INVENTION

A. Technical Field

The present invention generally relates to a carrier device. More specifically, the present invention relates to a device for holding or carrying the backpack, while user wearing the backpack.

B. Description of Related Art

Backpacks use has increased in recent years. The backpacks are used for day hiking and performing other outdoor recreational activities. The backpacks rely on shoulder straps, and, optionally, hip straps, to carry the load. A backpack with standard shoulder straps primarily carries the load on the shoulders. When the backpack worn by a user, the entire weight or load of the backpack is resting on the shoulders of the user. In operation, the entire load from the backpack is directed vertically through the shoulder straps onto the shoulders of the user creating discomfort to the user. To compensate for the excessive load on the shoulders the user could unnaturally hunch forward subjecting themselves to ill posture and potentially bad back problems. Moreover, repeatedly tugging at the shoulder straps of the backpack, while walking is distracting, resulting in a repeated shifting back and forth of the center of gravity of the backpack, and thus making the walking uncomfortable.

The use of backpacks is not limited to aforementioned fields. Students for carrying books and supplies between school and home use backpacks. In the present days, the students need to carry more books and supplies than in the past. The school institution, distracted by the full course of the lessons, despite the laws that set the maximum limit of the weight of the backpack equal to 10-15% of the weight of the user, does not care about the amount of books, notebooks and accessories carried by the students between the school and the home. In addition to the incorrect position of the backpack, other incorrect postural attitudes such as sitting in front of the personal computer (on average 2-3 hours a day) and sitting on the sofa in front of the TV (as many hours) are additional actions carried by the students, which deteriorate the health of the students.

Various disadvantages are associated on carrying the heavy load on the backpack The heavy load on the backpack causes fatigue, discomfort, poor posture, and even musculoskeletal disorder, injury, head and neck aches, muscle spasms, and poor blood circulation to the arms and hands of the user resulting from blood constriction of the straps and the loaded backpack.

From the above, there exists a long-felt need for a device that helps in maintaining the correct posture of the user. Further, there is need of the device that distributes the load from the shoulder of the user, preventing the user to bend forward while walking or performing any activity.
