Description

Technical Field

[0001] This utility model relates to the field of shoulder straps, specifically a weight-reducing shoulder strap. Background Technology

[0002] Baby carriers have become an indispensable tool in modern life for students, musicians, and travelers. Whether navigating campus, performing at a concert, or exploring new landscapes on a journey, baby carriers play a vital role. Most baby carriers on the market are adjustable in length to meet the needs of different users and make them more convenient to use. However, the primary function of these baby carriers is to distribute the weight of the load onto the user's shoulders.

[0003] Although the shoulder straps are adjustable, in actual use, carrying certain items for extended periods (such as cameras, cellos, drawing boards, etc.) can still put significant pressure and strain on the shoulders. Over time, the shoulder muscles gradually become fatigued and sore, and may even lead to discomfort and pain for the user.

[0004] For example, prior art JP2014008172A discloses a shoulder strap with adjustable length. The strap is directly connected to the shoulder bag through connectors at both ends. Although it has the function of adjusting the length of the strap, it cannot solve the problem of shoulder pain when carrying the shoulder bag for too long.

[0005] Therefore, optimizing the shoulder strap design to improve the user experience and reduce burden is imperative. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention proposes a weight-reducing shoulder strap.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-2 As shown, this utility model discloses a weight-reducing shoulder strap, including: a first connecting member 1, a first elastic member 2, an adjustable shoulder strap 3, a shoulder pad 4, a sliding buckle 5, a second elastic member 6, and a second connecting member 7; wherein, the first connecting member 1, the first elastic member 2, the adjustable shoulder strap 3, the sliding buckle 5, the second elastic member 6, and the second connecting member 7 are connected in sequence.

[0025] The adjustable shoulder strap 3 is a common type of adjustable shoulder strap found in existing crossbody bags. Its main structural form is consistent with that of existing technology JP2014008172A, featuring a common pull-button adjustable shoulder strap structure. The main difference between the technical solution used in this embodiment and existing technologies lies in the fact that, in existing technologies, the fixed end of the adjustable shoulder strap is directly fixed with a first connecting member, meaning the fixed end of the adjustable shoulder strap refers to the end where the relative position of the strap body does not change during length adjustment; the adjustable movable end of the adjustable shoulder strap is connected to a second connecting member via a sliding buckle, thereby ensuring that when the length of the adjustable shoulder strap changes, the sliding connection between the sliding buckle and the adjustable shoulder strap ensures that the second connecting member is always at the other end of the adjustable shoulder strap. Here, the adjustable movable end of the adjustable shoulder strap refers to the end where the relative position of the strap body changes during length adjustment.

[0026] In this embodiment, to address the problem that traditional adjustable shoulder straps cause shoulder pain over time when carrying specific items (e.g., cameras, cellos, drawing boards) because the weight of the load directly presses on the shoulders, a first elastic member 2 is provided between the fixed end of the adjustable shoulder strap 3 and the first connecting member 1, based on the traditional adjustable shoulder strap structure. The two ends of the first elastic member 2 are fixed to the fixed end of the adjustable shoulder strap 3 and the first connecting member 1, respectively. Similarly, a second elastic member 6 is provided between the sliding buckle 5 and the second connecting member 7 located at the adjustable movable end of the adjustable shoulder strap 3, with both ends fixed to the sliding buckle 5 and the second connecting member 7, respectively. The connecting member can take the form of a quick-release buckle, D-ring, snap fastener, connecting ring, safety lock, etc., and is not limited in this embodiment.

[0027] The weight-reducing shoulder straps provided in the above embodiments are used by the user by hanging the elastic shoulder straps on their shoulders. During walking, the up-and-down vibration of the straps caused by the load is effectively cushioned by the elastic components, thereby significantly reducing the pressure exerted on the user's shoulders. At the same time, the rebound force of the elastic components also reduces the effort required by the user, thereby reducing the burden on the shoulders and improving overall comfort. In addition, since both ends of the adjustable shoulder straps are connected to the carried items via elastic stretch bands, the elastic components can provide a certain degree of cushioning when subjected to external forces, allowing the user to walk easily and freely while wearing the shoulder straps, saving effort and making it convenient.

[0028] In addition, to further reduce the burden on the shoulders, shoulder pads 4 are also provided on the adjustable shoulder straps 3. The shoulder pads 4 are fitted onto the adjustable shoulder straps 3, such as... Figure 1 The shoulder pad 4 shown can be spindle-shaped, oval, or rectangular to increase the contact area between the shoulder and the shoulder strap, reduce the unit weight on the shoulder, improve the carrying experience, and relieve shoulder pain.

[0029] Those skilled in the art will know that the materials of the aforementioned adjustable shoulder strap 3 include, but are not limited to, nylon, polyester fiber, cotton, polyurethane, leather, mesh, canvas, etc.

[0030] Preferably, the structure of the first elastic element 2 includes, but is not limited to, elastic compression belts, elastic ropes, springs, and other structures that can be used in the shoulder strap to provide elastic cushioning.

[0031] As can be seen from the accompanying drawings, in the embodiments of this utility model, the fixed connection and relative sliding of each component can be achieved by conventional methods of the prior art. The specific implementation method will not be further described in this utility model specification.

[0032] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
