Description

The invention relates to a backpack with two shoulder straps and two connected to its rear wall fins of a hip belt, according to the preamble of claim 1 and according to the preamble of claim 2.

From the DE 20 2010 012 046 U1 a backpack, in particular a bicycle backpack is known which comprises a container and a carrying strap. The strap is connected in particular in an upper region and in a middle or a lower region with the container of the backpack. To connect the carrying strap to the container, a pivoting element is provided, in particular in the upper region of the container.

The DE 20 2010 012 047 U1 also discloses a backpack having a container. There are two straps provided, which are connected at their upper ends to the upper portion of the container.

Known from the prior art backpacks, however, often have the disadvantage that they rest with their back on the back of the wearer and beyond the backpack during walking continuously from one side of the body to the other side oscillates back and forth.

The invention therefore has as its object to provide a backpack, the carrier is not exposed to the disadvantages of the prior art known backpack models.

The object is solved by the features of claims 1 and 2.

The backpack according to the invention comprises two shoulder straps and two fins of a hip belt connected to its rear wall. Each fin is connected via a closing belt with the closure of the hip belt. In addition, each closing belt has a separate belt tensioner. Each fin is further connected via a Lageverstellgurt with the backpack, the direction of the Lageverstellgurtes is deflected in the fin area. In addition, each Lageverstellgurt is connected via the one guide eye, each with a closing strap.

The backpack according to the invention is further distinguished by the fact that in each case at least one pad is attached to the fins and / or on the rear wall and / or on the shoulder straps. The pads of the fins, the rear wall and the shoulder straps form a continuous support surface. In addition, the upholstery attached to the rear wall has a channel which constitutes a ventilation channel and / or forms a channel for receiving the backrest of the carrier.

Using the shoulder straps of the backpack, the wearer fixes his backpack in the shoulder area. In addition, the shoulder straps allow the wearer of the backpack to move his arms freely while the backpack is on his back.

Under the waist belt is an additional attachment means of the backpack to understand, which is located in the region of the hip of the wearer. The hip belt comprises in the subject matter of the patent application two fins which are pivotally mounted against each other on the backpack. The hip belt allows the wearer to fix his backpack around his hips.

The fins are fastened with their, facing away from the closure of the waist belt front side of the backpack and are mutually pivotable. The fins can be attached to each other at a distance to the backpack, so that between the opposite end faces on the back of the backpack creates a ventilation duct.

Each fin of the hip belt is connected with a respective closing strap. Each closing belt is fastened with its fixed end to a respective part of the common closure of the hip belt. To close the closure of the waist belt, the two parts of the closure are locked together.

The straps are also adjustable in length and fix the fins of the waist belt on the body of the wearer. For mutual locking of the closure of the hip belt snaps are used. For releasable positive or non-positive connection of the fins of the hip belt with each other, however, other technical closure devices can be used.

For the production of the backpack according to the invention washable materials are used which absorb sweat and are additionally breathable. Furthermore, the structures of the backpack must be sufficiently tear-resistant and weather-resistant.

The invention provides a continuous support surface formed by the pads which are disposed on the fins of the waist belt, in the region of the back of the backpack and on the insides of the shoulder straps. To form the continuous support surface, the padding of the different areas (hip belt, back, shoulder straps) of the backpack are the same in width and material thickness.

The advantage is that the backpack is not flat on the back of the wearer comes to rest, but indirectly and indirectly via the various pads with the back of the wearer is in communication. Different thicknesses of juxtaposed pads would otherwise lead to bruises on the body of the wearer and significantly affect the comfort of the backpack. Differences in the width, material thickness and strength of the cushioning material can lead to painful hardening of the musculature during prolonged wearing of the backpack.

The backpack rests only with the padded surfaces on the body of the wearer. The non-padded areas of the backpack are therefore objected to by the body of the wearer and serve as ventilation channels. The surfaces between the wearer's body and the backpack are better ventilated. The wearer does not sweat to the extent that it does, even in long wearing times, as in the case when the backpack flies flat on the body.

Overall, the backpack according to the invention helps to reduce the fatigue of the wearer, even with long wearing times. Additional, previously affected body parts remain unaffected due to the higher comfort of the backpack.

Depending on the size and load of the backpack, upholstery modules can be replaced and replaced with replacement pads. However, it is important that the support surfaces of the pads in the different areas of the backpack match in width, height and material thickness to maintain the continuous pad support surface.

The pads may be located in the region of the back of the backpack about axially in relation to the backpack length. In addition to a parallel arrangement of at least two pads in the region of the back, which serves to relieve the back of the wearer, the back pad can also be arranged laterally outwardly disposed on the rear wall of the backpack. As a result, the ribs of the carrier can be additionally relieved.

The free end of the closing belt is passed through an eyelet of a Gurtstrammers and locked in this. Locking takes place by turning the loose end of the closing strap in the eyelet by 180 °. The belt tensioner is released by tilting the eyelet by approx. 40 ° in the direction of the closing belt, which releases the loose end clamp in the eyelet. By tilting the Gurtstrammers the loose end of the closing strap can be pulled through the eyelet again.

The invention understands the term Lageverstellgurt a connection between a fin of the waist belt and the backpack. The Lageverstellgurt serves to pull the backpack closer to the hip of the wearer and fix in this position. The position adjustment strap stabilizes the backpack in the area of the wearer's hips and protects against unwanted back and forth wobbling while running.

The advantage of the invention is that the seat of the fins of the hip belt can be fixed to the hips of the wearer by pulling on the loose ends of the straps. At the same time the Lageverstellgurte be pulled towards the closure of the hip belt, whereby the backpack is pulled closer to the hips or the buttocks of the wearer is used. Contrary to previous backpacks, the wearer of the backpack can therefore by train to the loose ends of the straps on the one hand improve the fit of the waist belt on his hips. On the other hand, the train at the loose ends of the straps causes a closer connection of the two rear sides of the backpack to the hip of the wearer.

The Lageverstellgurt is attached at one end to the backpack and attached with its other end to the fin of the waist belt. Contrary to its direction of Lageverstellgurt is deflected. For connection with the closing belt a connection eye is provided. To connect the closing belt with the Lageverstellgurt an eyelet is provided. In the area of their attachment to the waist belt Lageverstellgurt is performed by the eyelet in. Opposite the Lageverstellgurt the locking strap is also passed through the eyelet. The eyelet thus represents a connecting link between the Lageverstellgurt and the closing belt. If the closing belt is pulled further through the eyelet by pulling with its loose end, the eyelet simultaneously pulls the position adjustment belt in the direction of the closure of the hip belt. The eyelet can be a three-leg eyelet. It is also any other technical device conceivable through which the closing belt can be pushed through and folded against its direction and can be fixed. A middle bridge can be firmly connected on both sides with the eyelet. on the other hand the web can also be pivoted on its own side to the eyelet and bridge the guide eye through which the closing belt and the Lageverstellgurt be passed.

Depending on the size and weight of the backpack, the width and thickness of the closing belt or the Lageverstellgurtes vary. Using the belt tensioner, the two opposing fins of the hip belt can be adapted and fixed to the respective hip circumference of the wearer. At the same time the pull on the loose ends of the closing strap causes a better fixation of the outer sides of the backpack on the body of the wearer.

The better fit of the waist belt and the backpack on the body of the wearer painful rubbing of the backpack or the straps on the body is avoided. The shoulder straps can be additionally lengthened or shortened and thus adapted to the circumference of the upper arms of the wearer.

According to an alternative embodiment of the invention, a stiffening element is attached to the rear wall. A further embodiment provides that the stiffening element comprises a carrier plate and a frame applied to the carrier plate.

The stiffening element comprises a support plate, which consists of PE plastic. On the support plate, a frame made of spring steel is applied. The frame may be in the shape of a cloverleaf and may be convex or concave. The inclination of the frame may be directed towards or against the direction of the wearer's back. The stiffening element can be attached via Velcro straps on the back of the backpack. In addition, an insertion pocket can be provided for receiving the stiffening element.

The invention also provides that the Lageverstellgurte are adjustable in length. The wearer can additionally optimize the wearing comfort by being able to regulate the distance between the backpack and the hip, depending on the degree of difficulty of the covered distance, by changing the length of the adjustment straps. The wearer first adjusts the fit of the hipbelt by pulling on the loose ends of the strap. At the same time he pulls the sides of the backpack closer to the hip belt via the Lageverstellgurte. The closing belt of each side holds the eyelet of the belt tensioner, which is simultaneously connected to the Lageverstellgurt that page.

In addition, the wearer now also has the option of individually adjusting the position adjusting straps one after the other, depending on requirements and convenience.

Preferably, the connection region of the position adjustment strap on the backpack is wider relative to the length of the backpack than the connection region of the position adjustment strap on the hip belt. This creates a three-point connection whereby two points of the connection to the backpack attack one another, while the third point of the connection lies in the region of the fin of the hip belt. As a result, an additional stabilization of the backpack is achieved with respect to the waist belt.

It is also conceivable that the two attachment points on the backpack can be moved over the length of the backpack.

According to another preferred alternative of the invention, the Lageverstellgurt is divided into a top and bottom chord, the top chord and the bottom chord are spaced from each other for attachment to the backpack and approach each other for connection to the Lageverstellgurt. In order to allow an optimal connection of the Lageverstellgurtes on the backpack and at the same time to reduce the carrying weight of the backpack Lagelestellgurt is designed as Obergurt and Untergurt. Depending on the size of the backpack and other intermediate straps can be used.

Furthermore, it can be provided that the belt tensioner has a three webs comprehensive eyelet through which a loose end of the closing belt is passed.

The belt tensioner comprises an eyelet, which may have three webs. The loose end of the closing belt is passed through the eyelet and deflected counter to the running direction of the closing belt. The deflected loose end of the closing belt is then locked by the third web of the eyelet. To solve the locking by the belt tensioner and to release the loose end of the closing belt, the eyelet is tilted approximately 40 ° relative to the closing belt. In the present case, a three-eyelet eyelet is assumed as an example. However, the three-leg eyelet is only exemplary and in no way exclusively meant. It can also find other technical devices use that make a releasable locking by clamping the closing strap possible.

Moreover, it is preferred that the belt tensioner is arranged in the region of the loose end of the closing belt. In another embodiment of the invention, the belt tensioner preferably arranged in the region of the closure of the hip belt on the closing belt.

Preferably, the invention further provides that the respectively arranged on the fins, the rear wall and the shoulder straps each have at least one pad a same width and / or height.

The invention ensures increased wearing comfort. It is created according to the height and the width of even bearing surface. Pressure points on the body of the wearer are avoided as well as regional overloading of the body. The support of the backpack on the body of the wearer is purposefully limited to particularly padded surfaces, whereby the wearing comfort is significantly increased.

A further embodiment of the invention provides that the channel formed on the rear wall of the backpack is formed by mutually parallel pads.

The invention provides that in the region of the back of the backpack, a channel is created in which the backbone of the wearer is protected from contact with contents of the backpack. In addition, one serves the protection of the backbone in falls in the field. In addition, the groove formed on the rear wall of the backpack can be formed by a depression which is introduced into the at least one pad.

According to the invention, the pad ventilation grooves, which extend at an angle to the longitudinal direction of the cushion body.

Ventilation grooves are provided obliquely to the upholstery bodies. These ventilation grooves can be introduced between individual upholstery bodies or else in the upholstery body itself. They are used to remove sweat or rainwater to the outside and away from the body. This allows a faster drying of the wet body and thus prevents a cold the wearer.

Between the cushions of the hip belt and / or the padding attached to the rear wall and / or the padding of the shoulder straps, ventilation channels preferably run. Furthermore, it is provided that the pads of the hip belt and / or the pads of the rear wall and / or the pads of the shoulder straps abut each other in the transition region.

The weight of the backpack should be distributed as evenly as possible on the body of the wearer. For this purpose, the continuous support surfaces of the pad of the hip belt, the rear wall and the shoulder straps are provided. The ventilation channels should run vertically and transversely to the pad surfaces to allow for improved air circulation. Between the individual areas (hip belt, back, shoulder straps), the upholstery bumps against each other. Therefore, the upholstery is flattened at the end faces, so that damage to the upholstery in the case of tilting facing one another is precluded.
