Bag or rucksack

Abstract

A bag or a rucksack has a base part having an enlargeable packing volume and first and second connection elements, between which a flexible wall element is arranged. A first packing volume is formed when the first and second connection elements are connected and the wall element is arranged in the first packing volume at least in part, and an expanded packing volume is formed when the first and second connection elements are separated. An additional part is provided which has an additional packing volume, and a first additional connection element is provided on the wall element and a second additional connection element is provided on the additional part. The additional part can be fastened to the base part by means of the additional connection elements.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Other objects and features of the invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.

(2) In the drawings,

(3) FIG. 1 shows a rucksack having a first packing volume;

(4) FIG. 2 shows a rucksack having a second packing volume;

(5) FIG. 3 shows an additional part of the rucksack; and

(6) FIG. 4 shows the rucksack comprising the additional part.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(7) FIG. 1 shows a rucksack 1 comprising a base part 2 which defines a first packing volume. The interior, and thus the packing volume, of the base part 2 is accessible via a closable access opening 3. In the embodiment shown, the access opening 3 is closable by means of a zip fastener.

(8) Compression straps 4, 5 are provided on the base part 2, on which straps a closure element 6, 7 is arranged in each case which cooperates with corresponding closure elements 8, 9 on the base part 2. A fine adjustment of the packing volume of the rucksack 1 can be carried out by means of the compression straps 4, 5. The rucksack 1 further comprises a shoulder strap 10 and a waist strap 11. In order to be able to more easily store utensils, a pocket 12 which can be closed by a zip fastener, or a compartment, is provided on the base part 2.

(9) In order to enlarge the packing volume, closure elements 13, 14, which in this case form a zip fastener, are provided. If the closure elements 13, 14 are released from one another, as can be seen in FIG. 2, a wall element 15, arranged between the closure elements 13, 14 and made of a flexible material, can unfold. The packing volume of the base part 2 is enlarged as a result. Since, in the embodiment shown, the connection elements 13, 14 do not extend in a completely annular manner, i.e. the ends do not touch or are not arranged close together, the wall part 15 does not have a uniform width, but rather is designed so as to be wedge-shaped in the end regions thereof or tapers to a point in the end regions thereof. It would also be conceivable, however, to design the connection elements 13, 14 so as to be longer, such that the ends thereof almost touch. In this case, the wall element 15 could be designed having a constant width, and the packing volume could be enlarged yet further.

(10) A first additional connection element 16 is arranged on the wall element 15. Said first additional connection element 16 is used for connection to an additional part (FIG. 3). It is furthermore visible, in FIG. 2, that the closure elements 6, 8, 7, 9 have been released from one another. It can in addition be seen that a further closable pocket 17 is arranged in the upper region of the base part 2.

(11) FIG. 3 shows an additional part 20 which defines an additional packing volume. The additional part 20 comprises a second additional connection element 21 to which the first additional connection element 16 can be connected. In this way, the additional part 20 can be fastened to the base part 2, and the packing volume of the rucksack 1 can be enlarged.

(12) The additional part 20 also comprises an access opening 22, which is in particular closable by means of a zip fastener. Furthermore, the additional part 20 comprises a pocket 23 or compartment, which is in particular closable by means of a zip fastener. Closure elements 24, 25 are provided for cooperating with the closure elements 6, 7 at the ends of the compression straps 4, 5.

(13) A further closure element 26, which can cooperate with a further closure element on the base part 2, is located at the lower end of the additional part 20. The closure elements can be designed as clasps for example.

(14) A further closable pocket 27 is provided in the region of the closure element 26.

(15) It can be seen, in this case, that the second additional connection element 21 is not peripheral, but rather is arranged just in one portion. Thus, a region remains in which the additional part 20 is not connected to the base part 2. In this region, which in this case is located at the lower end of the additional part 20, objects can be pushed between the base part 2 and the additional part 20. Said objects can for example be secured by a compression strap, the closure element of which cooperates with the closure element 26.

(16) FIG. 4 now shows the rucksack 1, in which the additional part 20 is connected to the base part 2. The compression straps 4, 5 were connected to the connection elements 24, 25, such that fine adjustment of the packing volume can be carried out. In this case, it can also be seen that the closure element 26 is connected to a closure element arranged on a further compression strap 28.

(17) Although only a few embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
