Description

The present invention relates to a backpack, and more particularly to a backpack for bicycling.

In recent years, backpacks for sports applications have become more and more popular. Backpacks are useful for many different sports, but especially for outdoor activities such as hiking and biking. To comfortably support the backpack on the wearer's back, it is known to provide cushioning shoulder straps, such as straps with cushioning material that extends over the backpack wearer's shoulders. There is.

For example, US Patent Application Publication No. 2011/0290843 discloses a backpack with a convex back panel, the convex back panel of the backpack being the backpack and the wearer's back. It can be curved outward from the center of the wearer's back to minimize contact between them. The backpack may have a pair of shoulder straps operably connected to a convex back panel to secure the backpack to the wearer's back.

In addition, US Pat. No. 6,164,509 moves the center of gravity of the bookpack to a higher position on the bookpack and closer to the wearer's body, which is borne by the wearer's shoulders. An ergonomic bookpack that includes a series of top straps, side straps, bottom straps, and optional support members that serve to significantly redistribute the load of the book along the longer parts of the body and back. Is disclosed.

However, backpacks known in the art do not allow optimal and reliable adjustment of their position on the wearer's back. However, optimal and reliable adjustment is very important for performance-oriented applications such as downhill viking, where the backpack receives the great force of gravity and sudden impact.

U.S. Patent Application Publication No. 2011/0290843 U.S. Pat. No. 6,164,509

Therefore, the fundamental task of the present invention is to further optimize the backpack to at least partially overcome the above-mentioned problem of reliable positioning of the backpack on the wearer's back.

The above-mentioned problems are at least partially solved by the backpack described in the independent claims. An advantageous embodiment is included in the dependent claim. It should be noted that any backpack set forth in claim 1 and its dependent claims may further include the features of the backpack set forth in independent claim 8 and its dependent claims.

A first aspect of the invention relates to a backpack comprising a body, at least one cushioned shoulder strap, and at least two stabilizing straps each connecting a distal portion of at least one cushioned shoulder strap to the body. In the present invention, at least one cushioned shoulder strap has a proximal portion closer to the body and a distal portion further away from the body. Therefore, the proximal portion of the cushioned shoulder strap may also be considered as the upper portion of the cushioned shoulder strap adjacent to the wearer's shoulder, and the distal portion may be considered as the lower portion of the buffered shoulder strap.

Any unwanted change in backpack position during sports applications such as downhill viking will impair the wearer's performance. We provide two stabilizing straps for the cushioned shoulder straps, which is sufficient to keep the backpack firmly and comfortably in its proper position on the wearer's back. I understood. Therefore, unintentional movement of such a backpack on the wearer's back, such as movement towards the wearer's head, can be reliably avoided.

At least two stabilizers may be connected to the body at the first and second stabilizers, with the first stabilizer closer to the proximal portion of the cushioning shoulder strap than the second stabilizer. Can be placed. For example, when the backpack is used on the wearer's back, the first stabilizing part may be placed closer to the wearer's shoulder than the second stabilizing part. Such an arrangement of the stable anchors of the stable straps can further optimize the secure positioning of the backpack.

In some embodiments, when the backpack is used on the wearer's back, the first stable fixation may be located in the wearer's thoracic region. In addition, the second stable fixation may be located in the lumbar region of the wearer. Therefore, the first stabilizing portion may be located in the middle portion of the backpack and the second stabilizing portion may be located in the lower portion of the backpack. These embodiments are along the wearer's back because the distance between the stabilizer strap in the wearer's thoracic region and the wearer's axilla is much shorter than with traditional backpack straps. It also helps to avoid unwanted exercise in the backpack. Thus, even in sporting applications such as downhill viking with strong external forces, the described backpack can essentially remain in an adjusted position on the wearer's back.

In some embodiments, the distance between the first stable fixation and the second stable fixation is greater than the distance between the first stable fixation and the proximal portion of at least one cushioning shoulder strap. Can also be shortened. For example, when the backpack is used on the wearer's back, the distance between the first stable fixation and the second stable fixation is on the first stable fixation and the wearer's shoulders. It can be shorter than the distance to the top edge of the adjacent body. We have found that such geometry further enhances the reliable adjustment of the desired position of the backpack.

In some embodiments, at least two stabilizing straps may be provided as a single strap that extends from the body to the distal portion of at least one cushioning shoulder strap and returns to the body. Providing the two stabilizing straps as a single strap can provide a simple and cost-effective structure. In addition, it is possible to easily adjust the stabilizing straps, eg, shrinking the entire single strap, to easily tighten the two stabilizing straps at the same time.

Another aspect of the invention relates to a backpack comprising a body, at least one cushioned shoulder strap, and at least two binding straps each connecting a proximal portion of at least one cushioned shoulder strap to the body. At least two binding straps are adapted to adjust the position of the proximal portion of at least one cushioning shoulder strap. In addition, at least two binding straps may be adapted to adjust the position of the proximal portion of at least one cushioning shoulder strap with respect to the lateral direction orthogonal to the longitudinal extension of at least one cushioning shoulder strap.

In the prior art described above, the cushioned shoulder strap is attached to the body without any adjustment potential, but embodiments of the present invention adjust and wear the position of the backpack on the wearer's back. It provides a radically new approach to improving a person's comfort. By having two binding straps, the position of the proximal part of the cushioned shoulder straps can be adjusted not only for a tighter fit, but also in other directions, such as laterally, to accommodate different shoulder widths. It becomes possible to do.

In some embodiments, at least two binding straps may be connected to the body at the first and second binding anchors. It is preferable that at least one of the first and second coupling fixing portions is arranged on the inner surface of the main body.

In some embodiments, the at least two binding straps may be provided as a single strap that extends from the body to the proximal portion of at least one cushioning shoulder strap and returns to the body. Similar to the stabilizing strap, such a structure reduces manufacturing costs and allows for easier tightening.

In some embodiments, the backpack may comprise a first and second pair of binding straps, the first pair being connected to the proximal portion of the first cushioning shoulder strap and the body. The second pair is connected to the proximal portion of the second cushioning shoulder strap and the body. In addition, the first pair of coupling straps can be connected to the second pair of coupling straps. Similarly, such an arrangement facilitates manufacturing and adjustment of the fit, as only a reduced number of binding straps need to be adjusted.

In addition, the connection between the first pair and the second pair of coupling straps can be located on the inner surface of the body. Such an arrangement can be exposed to dangerous situations as the backpack wearer can come into contact with trees and bushes, with the first pair of binding straps during sports applications such as downhill buffet or backcountry snowboarding. It is possible to avoid unintentional separation of the secure connection with the second pair.

In some embodiments, the body may include a back panel. Such a back panel can provide support to the body of the backpack and minimize contact between the backpack and the wearer's back. As a result, durable and breathable backpacks can be provided for sports applications.

In some embodiments, at least one of at least two stabilizing strap lengths may be adjustable. In addition, at least one of the lengths of at least two binding straps may be adjustable. Such embodiments provide a greater degree for various adjustments of the position of the backpack on the wearer's back so that optimized wearer comfort can be obtained.

In some embodiments, the backpack may have two cushioned shoulder straps and at least one support strap connecting the two cushioned shoulder straps. The support straps work with the stabilizing straps and / or the binding straps to keep the two cushioned shoulder straps in a comfortable and secure position on the wearer's back.

Hereinafter, aspects of the present invention will be described in more detail with reference to the accompanying drawings.
