Definitions

  • the present invention relates to an improved backpack or bag comprising a system for carrying the backpack orabag.
  • the level of comfort depends not only on the static load due to the weight of the object but also on the dynamic load.
  • the dynamic load For example, when a person is walking or running vertical movements and accelerations of the object can greatly increase the dynamic load compared with the static load. The faster a person is moving, generally, the greater the dynamic load will be for a given static load. Therefore, this problem is particularly important in athletic applications.

  • the object will generally not only move vertically but also horizontally.
  • the further the object moves away horizontally from the centre of mass of the body of the wearer the heavier the object will feel to the wearer.
  • generally the torque exerted by the centre of mass of the object about a pivot, which may be a contacting point of the object on the back of the wearer will increase, the further the centre of mass of the object is away from the centre of mass of the body of the wearer.
  • a problem underlying the present invention is thus to provide a carrying system for an object that provides greater wearing comfort than existing carrying systems, especially under dynamic conditions.
  • a backpack or bag comprising carrying system for carrying the backpack or bag, wherein the carrying system comprises: (a) an essentially elastic portion, (b) wherein the essentially elastic portion is attached to the backpack or bag at a first position located on the backpack or bag; and (c) a limitation arrangement, wherein a length of the limitation arrangement limits a maximum extension of the essentially elastic portion, and (d) wherein the limitation arrangement is attached at least at one second position on the backpack or bag that is different from the first position, and wherein the limitation arrangement comprises a limitation strap and a guiding portion, wherein the guiding portion is attached to the backpack or bag at the second position, and wherein the limitation strap is slidably attached to the guiding portion.
  • an "essentially elastic portion” may return to its unloaded length, apart from small deviations, after application of a force of up to at least 200 N, preferably 500 N.
  • a length of an "essentially elastic portion” increases by at least 1%, preferably 5% under application of a force of 100 N. The increase in length under a load, or a force, is referred to as "extension".
  • an advantage of the present invention is that the essentially elastic portion pulls the object towards the body of the wearer.
  • the wearer is the person carrying the backpack or bag by means of the carrying system.
  • the wearer may carry the backpack or bag on his back.
  • the essentially elastic portion will pull the object towards the back of the wearer.
  • a key insight of the inventors is that the essentially elastic portion is attached to the backpack or bag at a first position located on the backpack or bag, whereas the limitation arrangement is attached at least at one second position on the backpack or bag that is different from the first position.
  • the limitation arrangement may be arranged below the essentially elastic portion on the backpack or bag, i.e. the at least one second position is located below the first position on the backpack or bag.
  • “Below” means in this context “arranged under” in the common orientation of the carrying system and the backpack or bag, when the carrying system is worn by the user to carry the backpack or bag.
  • the limitation arrangement may be arranged above the essentially elastic portion on the object.
  • “Above” means in this context “arranged higher” in the common orientation of the carrying system and the backpack or bag, when the carrying system is worn by the user to carry the backpack or bag.
  • Either arrangement allows the backpack or bag to be pulled into a more upright arrangement, thus reducing the torque exerted by the backpack or bag about a pivot, which may be a contacting point between the backpack or bag and the wearer.
  • the limitation arrangement and / or the elastic portion may each be attached to the backpack or bag at more than one position.
  • the limitation arrangement in addition to the at least one second position, may be attached on the backpack or bag on a further position that may be different from the first position or may coincide with the first position.
  • the limitation arrangement is attached on the backpack or bag at least at one position (the "at least one second position" ) that is different from the first position.
  • the carrying system therefore advantageously dampens forces due to the vertical and horizontal movement of the backpack or bag during the movement of the wearer.
  • the limitation arrangement serves to stabilise the carrying system by limiting the maximum extension of the essentially elastic portion.
  • the limitation arrangement comprises a limitation strap and a guiding portion, wherein the guiding portion is attached to the backpack or bag at the second position, and wherein the limitation strap is slidably attached to the guiding portion.
  • the limitation strap may move to adapt to the anatomic requirements of the wearer and also during the dynamic movement in order to further dampen the forces due to the vertical and horizontal movement of the backpack or bag.
  • the guiding portion ensures sufficient stability by restricting the motion of the limitation strap to be along the guiding portion.
  • the guiding portion may comprise a guiding tape.
  • a tape may comprise any type of textile such as woven, non-woven, or knitted.
  • the guiding tape may comprise an elastomer, for example polyethylene, polypropylene, chlorosulfonated polyethylene, or polyester. This allows the guiding portion to be comfortable, low friction, and low-weight, especially compared with, for example, a metallic structure.
  • the limitation strap may be slidably attached to the guiding portion by means of a first essentially loop-shaped tape and/or a first ring.
  • a first "essentially loop-shaped tape" may or may not be a closed-loop.
  • the first ring may have a number of shapes including a circular shape, a rectangular shape, an oval shape, or variations thereof.
  • the first ring may or may not be closed.
  • a ring may be made from a hard material such as a metal or a hard plastic or it may be made from a soft material such as a soft plastic.
  • the first essentially loop-shaped tape or the first ring may comprise any type of textile such as woven, non-woven, or knitted. It is only important that the motion of the limitation strap is restricted to be along the guiding portion.
  • the essentially loop-shaped tape or the ring may comprise an elastomer, for example polyethylene, polypropylene, chlorosulfonated polyethylene, or polyester. This allows the first loop-shaped tape or the first ring to be comfortable, low-friction and low-weight.
  • an elastomer for example polyethylene, polypropylene, chlorosulfonated polyethylene, or polyester.
  • the limitation arrangement comprises a guiding portion and a first essentially loop-shaped tape and/or a first ring but no limitation strap. This allows a particularly lightweight construction.
  • the limitation arrangement may be less elastic than the essentially elastic portion.
  • less elastic means that a greater force is required to extend the limitation arrangement by a given amount, for example by 5% in length, than would be required to extend the essentially elastic portion by the same amount, for example 5% in length.
  • This difference may be effected by a different elastic modulus, also known as Young's modulus, and/or by a different thickness. Therefore, the limitation arrangement may effectively limit the maximum extension of the essentially elastic portion.
  • the elasticity of the limitation arrangement may be determined at least by the elasticity of the limitation strap, the elasticity of the guiding portion, and / or the elasticity of the first essentially loop-shaped tape or the first ring.
  • the at least one second position may be vertically separated from the first position by a first vertical distance.
  • the separation by a first vertical distance allows the tilt of the object in a static situation as well as the range of possible tilts during dynamic movement to be engineered to allow a more ergonomic fit and better shock absorption.
  • the first vertical distance may be at least 2 cm, preferably at least 5 cm, more preferably at least 8 cm. The greater the first vertical distance, the more stable is the orientation of the backpack or bag and the smaller is the range of possible tilts during dynamic movement.
  • the first position located on the backpack or bag may be located at a second vertical distance of at least 2 cm below the top of the backpack or bag, preferably at least 5 cm, more preferably at least 10 cm.
  • the inventors have found, that it is easier for the wearer to carry the weight of the object if the centre of mass of the backpack or bag is arranged as high as possible with respect to the centre of mass of the body of the wearer. This is especially true for backpacks or bags.
  • the limitation arrangement may comprise a cushioning element.
  • the cushioning element serves two purposes. First, it provides comfort to the wearer through its cushioning effect. Second, because of its thickness, the cushioning element may act as a pivot. In combination with the essentially elastic portion, this creates a lever for pulling the backpack or bag into a more upright position during use, thus leading to more ergonomic wearing properties.
  • the cushioning element may act as a shoulder pad. If the limitation strap is slidably attached to the guiding portion, this arrangement also allows the cushioning element to better adapt to the shape of a shoulder, therefore distributing the load more evenly than a conventional shoulder pad.
  • the essentially elastic portion may comprise at least a first layer and a second layer. This way, the properties of the essentially elastic portion may be engineered with a greater variety.
  • the first layer may comprise an elastic mesh.
  • An elastic mesh is breathable and lightweight and may be used to provide a highly elastic first layer.
  • the first layer may have a first elastic modulus
  • the second layer may have a second elastic modulus
  • the first elastic modulus may not be identical to the second elastic modulus. This advantageously increases the range of elastic properties that can be engineered for the essentially elastic portion.
  • the first elastic modulus may be greater than the second elastic modulus or alternatively the second elastic modulus may be greater than the first elastic modulus.
  • a low elastic modulus means that the material is more elastic, i.e. extends more under a given force.
  • the first layer may have a different length than the second layer. This further advantageously increases the range of elastic properties that can be engineered for the essentially elastic portion.
  • the first layer may be longer than the second layer.
  • the length is determined along a longitudinal direction of the first layer.
  • the essentially elastic portion will then first extend rather easily under application of force and then, when the second layer is extended to the same length as the first layer, a greater force is required to further extend the essentially elastic portion. This way, it is possible to engineer strength into the carrying system for heavy usage situations.
  • the limitation arrangement may have a third elastic modulus and the third elastic modulus may be lower than the first elastic modulus and the second elastic modulus. For example, if the limitation arrangement has the same thickness as the first layer and the second layer, the limitation arrangement may be less elastic than the first layer and the second layer. This way the limitation arrangement may effectively limit the maximum extension of the essentially elastic portion but allowing for a relatively low thickness and thus weight of the limitation arrangement.
  • the limitation strap and/or the guiding portion may comprise a woven textile. Woven textiles advantageously provide good strength and high breathability. Alternatively, the limitation strap and/or the guiding portion may comprise any other type of textile, such as non-woven or knitted textiles.
  • the essentially elastic portion may be attached to the limitation arrangement at a third position located on the limitation arrangement. This way, the stability of the carrying system is improved advantageously. Attached in this context may mean attached directly.
  • the carrying system may further comprise a retaining element attached to the limitation arrangement at a fourth position located on the limitation arrangement and a fifth position located on the limitation arrangement, wherein the essentially elastic portion is arranged between the retaining element and the limitation arrangement at the fourth position and the fifth position, and wherein the essentially elastic portion is not attached to the limitation arrangement at the fourth position and/or the fifth position. If the essentially elastic portion is not attached to the limitation arrangement at the fourth position and/or the fifth position, the adaptability of the carrying system is advantageously improved. However, if the essentially elastic portion is arranged between the retaining element and the limitation arrangement at the fourth position and the fifth position, there is also an excellent stability.
  • a lateral movement of the essentially elastic portion with respect to the limitation arrangement may be prevented or restricted at the fourth position and/or the fifth position. This improves the lateral stability of the carrying system.
  • the retaining element may comprise a second essentially loop-shaped tape or a second ring.
  • the second essentially loop-shaped tape or the second ring may have the same properties as the first essentially loop-shaped tape or the first ring, respectively, as described herein. Therefore, the second loop-shaped tape or the second ring is comfortable and low-weight.
  • the retaining element may comprise an elastomer, for example polyethylene, polypropylene, chlorosulfonated polyethylene, or polyester. Therefore, the retaining element is especially durable and low-weight.
  • the essentially elastic portion and the limitation arrangement may be part of a carrying strap.
  • the advantageous properties of the essentially elastic portion and the limitation arrangement are put to excellent use in a carrying strap.
  • the invention concerns a backpack or bag comprising at least one carrying system according to the present invention as described herein.
  • a backpack or a bag is typically worn over the shoulders and may be worn on the back. Therefore, the advantageous properties of the carrying system according to the present invention are beneficial for a backpack or a bag.
