ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a backpack with crosswise shoulder.
BACKGROUND OF THE INVENTION
Some backpacks are in particular for use in sports and leisure activities involving more or less pronounced motions of the arms obliquely to the direction of locomotion, in particular in the form of pendulum motion, for example in-line skating or skiing.
One such backpack is known, DE 296 15 828 U/U.S. Pat. No. 5,873,506. This backpack has an obliquely extending main shoulder strap with a lengthwise displaceable slide provided with two buckles to which the upper and lower portions of the other shoulder strap are alternatively fastenable.
The known backpack permits one- and double-sided wearing without faulty posture. Along with maximum freedom of movement it achieves a uniform weight distribution without cramping of cervical spine and back muscles and with relief of the spinal column.
However, the known backpack is not put on in the accustomed fashion by extending the arms through the two shoulder straps. One instead first draws the main shoulders strap over one's head and then fastens one or the other portion of the other shoulder strap alternatively to the slide. Use of the known backpack therefore requires instruction by expert personnel.
SUMMARY OF THE INVENTION
The object of the invention is to make it considerably easier to put on a backpack.
In the backpack of this invention, a snap buckle comprising a snap-in part and a receiving part is provided in the chest area. The upper portion of the first shoulder strap and the lower portion of the second shoulder strap are fastened to the snap-in part of the snap buckle. The upper portion of the second shoulder strap and the lower portion of the first shoulder strap to the receiving part.
When the snap buckle is open, a strap consisting of upper and lower strap portions connected by snap-in or receiving part is thus formed on each side. To put on the backpack one can therefore slip one arm through the strap on one side and the other arm through the strap on the other side in accustomed fashion when the buckle is open. Subsequently one need only snap the buckle together. It is thus extremely easy to put on the known backpack.
While the snap-in part is preferably frame-shaped, the receiving part is preferably formed by a plate. Each part preferably has two slot-shaped openings disposed at an angle. The upper portion of the first shoulder strap and lower portion of the second shoulder strap are guided through the two slot-shaped openings in the snap-in part. The upper portion of the second shoulder strap and lower portion of the first shoulder strap through the two slot-shaped openings in the receiving part. The force is guided by the straps uniformly through the slot-shaped openings in the snap-in part and receiving part into the two parts which form a massive assembly when the snap-in part is inserted. Therefore, heavy backpacks can also be formed according to the invention.
Since in the nested parts, the snap-in part and the receiving part, the force extends crosswise in accordance with the course of the straps, one can save material by providing recesses in the two parts in the areas outside the crosswise course of the force. Thus, both the snap-in part can have a recess between its two slot-shaped openings and the receiving part between its two slot-shaped openings.
For fastening and for shortening or lengthening the four strap portions, the upper and lower portions of the first shoulder strap and the upper and lower portions of the second shoulder strap, the slot-shaped openings preferably each have a center longitudinal bar which the particular strap portion twines around. That is, the free ends of the strap portions are inserted with their free end around the longitudinal bar through the particular slot on the side facing the snap-in part or receiving part and then through the slot in the reverse direction on the side facing away from the receiving part or snap-in part. Each slot is thus formed as a clasp for fastening and for changing the length of the strap portion between buckle and backpack.
So that the free end of the particular strap portion is additionally fixed after insertion through the slot, a loop is preferably provided around the particular strap portion between the snap-in or receiving part and the fastening of the particular strap portion to the backpack. This loop advantageously consists of a rubber-elastic band.
