Description

Backpack to be carried on the back with a corresponding backpack system.

Backpacks are known in many variations, designs and qualities for a wide variety of applications. In addition to the classic hiking backpacks, individual backpacks adapted to the needs of the respective carrier group are now available for almost every sport.

US 2008/245096 discloses a backpack which, in the closed state, consists essentially of the bottom, top, side surfaces, a surface to be supported on the back and a front surface, with an opening area on or along a surface, the surface to be worn on the back being configured with at least one flap , wherein the opening area is designed as a zipper that preferably runs along the center line of the back surface, which zips the circumferential opening of the backpack to a surface with preferably two, essentially triangular overhangs, which protrude upwards and downwards over the closed backpack body and are designed as flaps, forms, whereby a complete opening of the essentially tub-shaped backpack body, on the elongated surface to be worn on the back and the flaps, takes place by means of at least one zipper.

There are also numerous different approaches with regard to the openings of rucksacks and their closure options, such as roll-top closures, straps with cords or straps or zippers.

Like the classic rucksack, almost all known rucksacks are filled via an upper opening of a sack-shaped base body and / or the contents of the rucksack are accessed. In another variant, the main body of the rucksack is designed to be divided and, for example, with a zip fastener, it is accessible in two separately accessible areas by opening or folding over. This enables improved access to the respective areas of the backpack body. Known backpacks are preferably with backpack straps or a backpack system consisting of shoulder straps, a hip belt or waist belt as well Equipped with upholstery elements. When the rucksack is carried on the wearer's back, the orientation of the opening area is mostly directed upwards or can be closed laterally through an opening which is accessible, for example, with a zipper.

On the one hand, the more or less accessible opening area of a backpack while it is being carried on the back is disadvantageous because third parties may have easy access to the contents by opening fasteners or zippers unnoticed by the wearer and allowing contents to be removed from the backpack. The relatively limited opening area, such as the upper opening onto a sack-shaped base body when filling or emptying the rucksack, as is well known, is also cumbersome and it is not uncommon for you to clear out the entire contents in order to get to certain pieces of luggage. It is desirable and therefore the object of the invention to create a rucksack which is easy and comfortable to handle and in particular when accessing the contents and which prevents unnoticed access to the contents by third parties while being carried on the back will.

In particular, the object of the invention is to create the greatest possible access to the inner area of the rucksack, with which the filling and / or removal of individual objects or the entire contents can be handled simply, quickly and conveniently.

This object is achieved with the features of the characterizing part of claim 1. Developments and advantageous embodiments of the invention are included in the further claims.

According to the invention, a backpack is formed or shaped in the closed state from essentially the bottom, top, side surfaces, a surface to be worn on the back and a front surface with an opening area on or along the back surface, the surface to be worn on the back having at least one Fold-over flap is designed, the opening area being designed as a zipper that preferably runs along the center line of the back surface, which zips the circumferential opening of the rucksack into an area with preferably two, essentially triangular overhangs, which protrude upwards and downwards over the closed rucksack body and as flap flaps are formed, forms, whereby a complete opening of the essentially tub-shaped backpack body, on the elongated surface to be worn on the back and the flaps, takes place by means of at least one zipper, and thereby marked t that the at the back too carrying surface is provided with rucksack straps, which are designed as a backpack system which is divided along the zipper line.

In the preferred embodiment, the circumference of the essentially tub-shaped rucksack body is equipped with a centrally divided zipper, whereby when the zipper is closed, a surface is created on which an upward and downward protruding approximately triangular shape protrudes over the base body Tab is formed. These are folded over as flaps and fixed to the main body of the rucksack, thus forming an approximately rectangular area of the rucksack to be worn on the back. In an alternative embodiment, the rucksack body is cut in such a way that after pulling the zipper, only one of the flaps is created, which is fixed to the base body and thus a surface to be worn on the back is formed.

The at least one flap is folded over in the direction of the rucksack base body and braced on it, for which purpose a ratchet and / or snap lock is preferably used. There are clamping or latching elements that correspond to one another and a clamping band with latching or clamping means at a correspondingly different, corresponding point.

The latching or clamping means of the ratchet and / or clamp fastener on the clamping element side are preferably designed to be spring loaded, so that the clamping or locking between the corresponding elements can be carried out simply and with one hand to release the connection.

In another variant according to the invention, the at least one flap is provided with a holding, guiding or connecting element for a strap-like tensioning means and on the front surface of the backpack body opposite the surface to be worn on the back, a lashing, clamping or Arranged anchoring means, by means of which all the folding flaps can be tensioned or lashed.

A backpack system is preferably arranged or attachable to the areas of the circumference of the backpack body which, after the backpack is closed, form the surface to be worn on the back. This backpack system is preferably arranged symmetrically to the course of the zipper and divided on the backpack body. In alternative designs, this can be detachable as individual parts or as a complete backpack system with different straps and / or upholstery, divided or attached as a whole. In the preferred embodiment, the rucksack straps or shoulder straps and / or the hip belt are screwed from the inside of the rucksack, with thread-cutting screws and external, little bulky plastic nuts preferably being used from the inside of the rucksack.

In a preferred variant, straps are arranged on the shoulder straps for pulling the rucksack to the wearer's back and the position of the rucksack straps on the rucksack body can be attached in variable positions, which enables adjustments to be made to suit different anatomies of the wearer.

At the zipper ends of the at least one fold-over flap, a fixing means is preferably arranged by means of which the folded-over fold-over flap, which is placed on the base body and protruding over the base body, can be fixed. An adjustable ratchet lock is preferably arranged for this purpose. Alternatively, the flap is fixed on the base body with at least one magnetic element or a Velcro fastener or a surface covered with Velcro elements.

In the unfolded state, an essentially complete opening and access to the interior of the tub-shaped backpack body is thus possible.

This is a decisive advantage in handling compared to top loaders, in which a relatively large amount of the content has to be put out and put back in in order to get to certain content. Such a perfectly accessible rucksack can also always be loaded with optimal or desired weight distribution thanks to the practically complete opening area.

The rucksack is preferably equipped with two flaps which, when the rucksack is closed, protrude as a triangular protrusion downwards and upwards beyond the surface to be worn on the back. The half-zip straps of the opened zip, which can be equipped with a slider, but is preferably equipped with two sliders, form the circumferential edge of the essentially tub-shaped backpack body when the backpack is open. This can be ideally filled in this open state or individual objects can be located and removed very comfortably through the practically complete opening.

The interior of the backpack is preferably equipped with various stiffeners and / or stiffeners, which are designed as a rod or strut running lengthwise, approximately parallel to the zipper and / or as interlocking stiffening elements running across the closed zipper. Said stiffening rods, struts and interlocking stiffening elements are preferably arranged with and / or on flat, at least partially rigid plates which are arranged, preferably welded, inside the rucksack in the area of the upper tub-shaped rucksack body. The carrier elements such as shoulder straps and hip straps, which are preferably designed to be adjustable, are preferably also attached to these inner stiffening plates.

The length of the rod or strut running approximately parallel to the zipper gives the backpack longitudinal reinforcement of the back part in the closed state and stabilization of the opening of the tub-shaped backpack body in the open state. This does not collapse or bend inadvertently due to the stiffening rod or strut, which provides very convenient access to the inside of the backpack. The backpack can be comfortable on its surface opposite the back support surface and then opened, the opening is kept open thanks to the stabilizing bar or strut. As a result, the area to be worn on the back is protected from soiling when accessing the contents and thus the back of the wearer is protected from soiling. The detachable, interlocking stiffening elements that run across the closed zipper and that are positively connected when the zipper is closed give the backpack, and in particular the surface worn on the back, stabilization in the transverse direction. This is particularly advantageous for carrying the rucksack on the back by means of the rucksack system or the straps, since an even load distribution is guaranteed and the rucksack body is not severely deformed.

The backpack system itself is preferably designed symmetrically divided along the zip line and thus the opening. A back cushion or back cushion elements made up of several parts are also arranged to be divided or designed to be able to be arranged to the right and left of the zipper.

In the closed state of the zipper, which preferably runs through the center line of the surface to be worn on the back, the backpack is stabilized by means of the split back carrying system and perfectly adaptable and portable thanks to the detachable, interlocking stiffening elements that run across the closed zipper. When the zipper is closed, the flaps protruding upwards and downwards over the main body are folded up to the main body and releasably fixed to corresponding holding elements on the main body by means of fastening means attached to the ends of the zipper. This connection is preferably designed as an adjustable ratchet lock, by means of which the flaps can be attached very quickly, safely and appropriately to the base body. Alternatively, the fastening between the fastening means attached to the zipper ends and the corresponding holding elements on the base body can also be designed as a Velcro fastener, magnetic fastener or lacing connection or the like.

The back part of the rucksack is preferably concave in order to allow rear ventilation when worn on the back. In a further preferred embodiment, the back part and / or the upholstery elements to the left and right of the zip fastener are each equipped with nets stretched out on the outside or an air-permeable substrate.

The interior of the rucksack is preferably equipped with at least one transversely and / or longitudinally running, permanently attached or removable partition and / or tensioning device. A clamping device arranged in this way in the interior serves for simple compression and / or fixation of the contents inside the backpack. The at least one partition creates a separate area inside the backpack and can be designed as a pure partition wall or as an additional partition pocket and equipped with a closure element such as a zipper or a Velcro fastener and can also be completely removed from the interior. The dividing wall and / or inner pocket can be permanently incorporated into the interior of the rucksack or can be made removable, for example by means of a zip or Velcro fastener. The partition or inner pocket that can be attached to the interior of the rucksack and creates an area can, in a further variant, be designed as an organization system with different compartments. At least one avalanche buoyancy system can also be arranged inside the rucksack or it can be attached as an additional inner element. In a preferred embodiment, such inner pockets are arranged next to the zipper tape and / or in the area of the zipper ends, so these inner pockets can also be reached very quickly and easily by only slightly or partially opening the zipper on the back surface. For this purpose, it has been shown that it is advantageous to implement a zip fastener on the back surface with two sliders, which allow a partial opening to the center of the back surface; for this purpose, access to inner pockets in the area of the ends of the zip fastener is particularly convenient.

In its preferred embodiment, the backpack is a waterproof backpack and is equipped with a waterproof and / or pressure-tight zipper.

The fastening seams of the inner pockets and / or inner partitions are preferably sealed by the welded-on zipper strips.

In the following, the invention is described in more detail by way of example with reference to drawings, which show:

• Fig.1 a fully open backpack
• Fig. 2 a fully opened backpack with a partial area
• Fig. 3 a closed backpack with protruding zipper ends
• Fig. 4 a closed backpack with zipper ends attached to the main body
• Fig. 5 a trough-shaped base body or welding body
• Fig. 6 an overview of the various states of the backpack according to the invention.
• Fig. 7 a closed rucksack with folding flaps tensioned on the rucksack body which can be handled from one side.

In Fig. 1 and in Fig. 2 a backpack 1 according to the invention can be seen in the open state, the embodiment shown here on the surface 3 to be worn on the back, as in FIG Fig. 3 is easy to see, with a backpack system 4, consisting of rucksack straps 4.1, hip belt 4.4 and pads 4.2, 4.3. The surface 3 to be worn on the back is formed by folding in the protrusion 7 on the base body 6 while the backpack is being closed. In this embodiment, the zipper 5 runs in the closed state of the rucksack, as in FIG Fig. 3 and Fig. 4 shown, in the middle of the elongated surface 3 to be worn on the back.

The back carrying system 4, which consists of back straps 4.1, back cushions 4.2 and further upholstery 4.3 and hip belt elements 4.4, is designed in two parts in this form and the corresponding halves are arranged to the right and left of the zip fastener 5.

Since the surface 3 to be worn on the back is formed from the protrusion 7 that extends the tub-shaped base body 6 by corresponding folding in or folding down of the protrusion or the at least one flap 13, the surface 3 to be worn on the back is created with upward and downward directions The essentially triangular flaps 13 with the zipper ends 8 projecting beyond the main body. The zipper ends 8 are equipped with holding means by means of which they can be releasably attached to corresponding fixing elements 9 on the main body 6.

In a preferred embodiment, this connecting device is adjustable, for example by means of a ratchet strap, with which the protruding triangular element can be easily tensioned at the respective end of the zipper. The fastening of the zipper ends can also be solved with appropriately placed Velcro strips, Velcro surfaces, magnetic elements or magnetic areas or press studs or simple cords.

In Fig. 7 a preferred embodiment of a rucksack is shown in which the handling or releasing and tensioning of the flaps 13 can be carried out from one side of the rucksack. The at least one flap is provided with a holding, guiding or connecting element 21 for a band-like tensioning means 23, 24. As shown here, a central lashing, clamping or tensioning means 22 is arranged approximately in the middle of the front surface 25 of the rucksack, which corresponds to the flaps via, for example, straps, straps, cords 23, 24 and via which the flaps can be tensioned and applied to the front surface of the rucksack. The lashing, clamping or anchoring means 22 is blocked on a web 26 and the holding guide or connecting element 21 on the upper flap 13 is designed as a clamping and anchoring means.

As a result, the load on the upper flap can be relieved separately and the rucksack in the upper area can be opened quickly without having to lay the rucksack flat like a suitcase, as the lower flap remains taut. This allows the backpack to be packed and unloaded quickly in the upper area.

The central lashing, clamping or tensioning means 22, which is arranged approximately in the middle of the front surface 25 of the rucksack, can vary in its position, but is positioned in such a way that it is centered or closer to the top of the rucksack, i.e. closer to the in Fig. 7 flap 13 shown is arranged.

The backpack can be opened either completely or only at the top, standing or hanging from its upper side, without having to reach around on the lower side, if the backpack is to be opened completely, you only have to turn the backpack after releasing both straps or let it fall over

At this central lashing, clamping or tensioning means 22, the two flaps are tensioned by means of tensioning elements such as the belt straps 23, 24 shown and placed on the rucksack body. Due to the possibility of releasing the two folding flaps at the same time on the central lashing, clamping or tensioning means 22, both folding flaps can be released on its underside when the rucksack is standing and the rucksack can then be placed on the front surface 25, thus opening up the large opening area is accessible on the surface to be worn on the back. This design prevents the backpack to operate the opening elements and to open the backpack not on the The surface to be worn on the back must be placed and thus also that this surface is soiled when it is placed on the floor or other objects. This also effectively prevents soiling of the wearer's clothes who are carrying the backpack on their back.

The lashing device 22 made up of lashing, clamping or anchoring means is, as described, arranged in the upper area of the front surface of the rucksack removed from the back and set up and connected to the ends of the flaps 13 by means of belt straps 23, 24 and at least two clamping buckles 21 shown as examples . The clamping buckles can be equipped with a click fastener for quick release and the belt straps are guided around the front surface of the backpack. In a variant not shown, guides or guide pockets for the belt straps are arranged on the front surface, which on the one hand improves the appearance and supports positioning of the straps. The lashing device also has a stop for at least one belt strap for at least one flap so that it is not accidentally unthreaded.

In a further preferred embodiment, the zipper ends or the protruding triangular elements as well as an area on the base body are equipped with magnetic elements, with which the resulting triangular protrusion can simply be slipped over the base body after the rucksack is closed when it is closed and where the protrusion with the corresponding magnetic area is held on it .

The zip fastener 5 is preferably equipped with two sliders, which makes it possible to open only a smaller area of the backpack at a time. The interior is here, as in Fig. 2 to see, equipped with one or more partitions 10, which can be accessed very easily and quickly by opening the zipper with the upper slide. The partitions 10 are preferably designed to be adjustable and / or removable and can be used at various points and attached by means of Velcro connections, press studs or a correspondingly provided zipper.

In another variant, one or more partitions can also be arranged lengthways in the interior, thus creating a longer or larger detached pocket inside.

For easier and better compression and securing of the contents inside the rucksack, at least one tensioning device 11 as in Fig. 1 shown, provided inside, by means of which the content is fixed and compressed. As a result, the contents are secured against falling out too easily and they are compressed, which makes it much easier to close the rucksack and the zipper.

As in Fig. 1 and Fig. 2 shown, the backpack is equipped in a preferred embodiment with at least one, inner stiffening means, designed as a stiffening plate 12, which in the combination shown of the longitudinally arranged, essentially parallel to the zipper tape extending rod-shaped element 15 and the stiffening plates 12 to one Contribute to the open position of the backpack.

Further stiffening elements 16, 17, which run across the closed zipper 5 and interlock positively when closed, stabilize the backpack and in particular the position around the waist. The hip belt 4.4 is attached to the stiffening plates 12 on which the interlocking stiffening elements 16, 17 are arranged, so that the rucksack can deform less and is comfortable to carry.

In Fig. 5 and in Fig. 6 At the top left, a base body 20 of the rucksack or rucksack body is shown which, through its closed surfaces, forms a trough-shaped body. The tub-shaped body opened in this state is equipped with a zipper 5 on its periphery, as in FIG Fig. 6 Shown above right, with the ends 8 of the zipper in the middle of the shorter side. By buckling the upper area 7 of the base body 6 and closing the zipper 5, the closed backpack is obtained according to FIG Fig. 3 and Fig. 6 bottom left with a surface 3 to be worn on the back and folding flaps 13. The folding flaps 13 protruding above and below the base body 6 are turned against the The base body is folded in, which creates a flat, slightly concave flat design to be worn on the back.

The flaps are releasably fixed in this position with the fastening elements, such as preferably with an adjustable ratchet or clip fastener.

After preferred embodiments of the invention have been described with reference to the accompanying drawings, it should be noted that the invention is not limited to these precise embodiments and that various changes and modifications can be made therein by a person skilled in the art without departing from the scope of the invention as he is defined in the accompanying claims.
