FIELD OF THE INVENTION
The present invention relates to a device for carrying an object. The device comprises first and second shoulder straps and a back portion. Devices of this type are generally used for carrying an object on the back of a person. One type of object to be carried by the device is, for example, a container for a liquid, such as water or another liquid for drinking. For example, one type of object to be carried by the device is a hydration system, comprising a container for a liquid and a tubing for conducting the liquid inside the container to the mouth of a person. Such hydration systems are, for example, used within sports and outdoor life. Devices of this type are generally arranged as a harness or similar connected to a carrying structure to form a backpack.
PRIOR ART
A plurality of different types of devices for carrying objects are known in the prior art. Numerous types of backpacks have been known for a long time. One such type of backpack comprises shoulder straps, a back portion and waist straps to be fitted around the waist of a person. The waist straps are provided with a buckle for connecting the ends of the waist straps. The back portion can be provided with an element forming a container for carrying objects. Alternatively, the back portion comprises fastening straps or a structure for fastening one or more objects to it. The shoulder straps and the waist straps can be adjustable in length, for example, by running through a fastening buckle, wherein the strap running through the fastening buckle can be pulled further through the fastening buckle for tightening, and wherein the fastening buckle can be tilted to allow loosening of the straps.
One problem with such prior art devices for carrying objects is that they are uncomfortable to use and give rise to a plurality of adverse effects due to their structure, particularly during physically demanding activities. Hence, there is a need for improving such prior art devices for carrying objects.
SUMMARY OF THE INVENTION
One object of the present invention is to avoid the above identified problems and provide a device for carrying objects which is comfortable to use, particularly during physically demanding activities, such as in sports.
The present invention relates to a device for carrying an object, comprising first and second shoulder straps, first and second chest straps to be fitted around the lower chest of a person, and a back portion connecting a first end of the shoulder straps with a first end of the chest straps, wherein second ends of the shoulder straps are connected to the chest straps, wherein second ends of the chest straps are detachably connectable to each other by means of a buckle, and wherein lengths of the chest straps are adjustable, characterised in that each of the chest straps comprises at least an elastic section, said elastic section being elastically extendable in a longitudinal direction of the chest straps. The structure of the device with shoulder straps, chest straps and the elastic section of the chest straps results in a device that is comfortable for a user to wear, holds the object to be carried in the desired position and minimises obstruction of chest expansion also during heavy breathing. Hence, the device according to the invention allows expansion of the chest, while simultaneously keeping the device, possibly with the object or objects to be carried, snuggly fitted on the user.
First strap parts of the chest straps can form the elastic section. Said first strap parts can comprise an elastically extendable outer portion and an elastically extendable inner portion, wherein the inner portion can be attached to the back portion. One end of the inner portion can be attached to the back portion and the inner portion can entirely overlap the back portion. Hence, the inner portion extends over the back portion or into a sleeve of the back portion, which results in the possibility of a substantially longer elastic section than if the end of the elastic portion was attached to the periphery of the back portion. A longer elastic portion of the chest straps makes it easier to reduce problems with breathing obstruction while maintaining the comfort of the device. The total length of the elastic section can be at least 100 mm. The length of the inner portion can be at least 50 mm. The elastic section can be elastically extendable at least 50% of its length in the longitudinal direction.
The chest straps can be provided with a stopping element, such as a non-elastic cord or similar, to prevent the elastic section from being elastically extended beyond a predetermined length. This prevents the elastic sections from being damaged due to exaggerated extension. Any elastic section of the device can be provided with such a stopping element.
The device can comprise first and second loops arranged with a space between them for length adjustment of the chest straps. A part of the chest straps can extend through either of said loops and can be detachably connectable to itself and length adjustable. Said structure results in substantial possibilities of size adjustment, first by selecting one of the first and second loops and then by connecting the chest strap in the desired position once it has been inserted through said loop. The chest straps can comprise a hook and loop fastener, such as VelcroTM. Such length adjustment possibilities in combination with the elastic section further improves the possibilities of achieving a snuggly fit without obstructing breathing.
The shoulder straps can comprise an elastic part forming a bounce absorber. As a result the device is further prevented from bouncing on the user, also during physically demanding activities, such as in sports. Further, the comfort can be increased. It is also believed that a combination of elastic sections of the chest straps and elastic parts of the shoulder straps result in a particularly favourable device for carrying objects with great comfort.
The back portion can be provided with a structure for receiving the object to be carried, such as a backpack compartment. Hence, the device can be formed as a backpack.
Further characteristics and advantages of the present invention will become apparent from the description of the embodiments below, the appended drawings and the dependent claims.
