DETAILED DESCRIPTION

(10) In the following an embodiment of the present subject matter is explained based on the drawings. It is noticed that the drawings show a specific embodiment as explained below and further alternative modifications as specified in the description are at least in part not illustrated. Further, same reference signs used in the Figures denote same components.

(11) As a preliminary point, the preceding description is in the following shortly summarized. A lid 1 of a backpack 30 is described below, wherein the lid 1 has a compartment 2 in which a standalone daysack 10 is arranged. The compartment 2 is transformable from a first state S1 in which the lid 1 is mountable to a backpack 30 to a second state S2 in which the standalone daysack 10 is usable independently from the backpack 30. In the first state S1 the standalone daysack 10 is stored within the compartment 2, wherein in the second state S2 the compartment 2 is inverted by turning the inside out so that the standalone daysack 10 is usable.

(12) In FIG. 1 a three-dimensional view of a backpack 30 and a lid 1 is shown. The lid 1 is positioned on the top of backpack 30 and connected to the backpack 30 by means and side release buckles 31, respectively. The side release buckles 31 allow an easy, cost efficient and reliable way to connect the lid 1 to the backpack 30. Further, such buckles allow quickly installing and uninstalling the lid 1 from and to the backpack 30.

(13) FIG. 2a shows the lid 1 from the top demounted from the backpack 30 and thus, in a first state S1 in which the lid 1 is mountable to a backpack. The lid 1 has a compartment 2 in which a standalone daysack 10 comprising a shoulder strap 4 is arranged (not shown). The compartment 2 comprises an opening 7 (not clearly visible in FIG. 2a). Further, a part of the side release buckles 31 is also depicted, wherein the shown part is the female counterpart 31a. On the top a male part 31b of further side release buckles 31 can be seen, also allowing a connection between the lid 1 and the backpack 30. Thus, on every corner of the lid 1 a side release buckle 31 is installed guaranteeing a reliable connection to the backpack 30.

(14) In FIG. 2b the same lid 1 as shown in FIG. 2a is depicted. The lid 1 is still in the first state S1. However, in FIG. 2b the opening 7 is identifiable and shown. The opening 7 is released by using a zipper 7a so that the inside of the compartment 2 is visible. The zipper 7a and the opening 7, respectively, extends along the width W of the lid 1, wherein the length of the zipper corresponds to the width W of the lid 1.

(15) Partly anticipating the following explanation, it is noticed that the length of the opening 7 and the zipper 7a, respectively, can also be longer or shorter in comparison to the width W of the lid 1. Thus, e.g. the more the zipper's length corresponds to the lid's width, the transformation from the first state S1 to the second state S2 of the lid is easier. In this context, it is preferred that the length of the opening is mainly equal to the width of the lid. In other words, the opening 7 extends such on the lid 1 that the compartment 2 is transformable from the first state S1 to the second state S2 and vice versa.

(16) The compartment 2—as shown in FIG. 2b—comprises in the first state S1 two sections 3, 16. The section 3 and the first section 3, respectively, stores in its inside the standalone daysack 10. The further section 16 of the compartment 2 and the second section, respectively, is empty so that it is possible to store e.g. food, first aid material and so on in its inside. Between the section 3 and the further section 16 the opening 7 is positioned. Thus an easy access to both sections is realized.

(17) As also can be seen within the compartment 2 a divider 8 is arranged. The divider 8 separates the section 3 and the further section 16. Moreover, the divider 8 holds the standalone daysack 10 in section 3 and thus prevents the daysack 10 from unattended falling out of the compartment 2 when releasing the opening 7.

(18) The divider 8 and the compartment 2 of the lid 1, respectively, comprises mounting means and snap buttons 9, respectively, for securing the position of the divider 8 within the compartment 2. Each snap button 9 comprises a male and a female part, wherein the female part is located at the compartment 2 and the male part at the divider 8. Snap buttons 9 allow an easy, quick and reliable connection between the divider 8 and the compartment 2.

(19) As can be further seen by FIG. 2b the divider 8 comprises a first upper and a second lower area, wherein the terms “upper” and “lower” refer to the orientation of the lid shown in FIG. 2b. The second lower area is sewed with and part of, respectively, the compartment 2. The first upper area located next to zipper 7a and the opening 7 comprises the snap buttons 9 as discussed above. It is also possible that the second lower area also comprises mounting means such as snap buttons or a zipper. By this, the divider 8 can be completely demounted from the lid 1.

(20) The releasing of the opening 7 and the zipper 7a, respectively, is the first step for transforming the lid 1 to a daysack 10. As a next step, the daysack 10 is pulled out of the compartment 2.

(21) FIG. 2c shows that a part of the daysack 10 is still in the section 3 and another part of the daysack is located outside the compartment 2 and the section 3, respectively. As can be seen in this figure the daysack 10 also comprises two shoulder straps 4 which are partly arranged within the compartment 2 and partly located outside as an intermediate state between the first and the second state S1, S2.

(22) The shoulder straps 4 comprise each a free end 4c, 4d and a fixed end 4a, 4b. The free ends 4c, 4d are for connecting to the daysack 10 so that the straps become usable for carrying the rucksack and daypack, respectively. The free ends 4c, 4d comprise each a buckle for quickly mounting the ends to the daysack 10. A corresponding counterpart interacting with the buckles is fixed to the daysack 10 and serves for detachably mounting the buckles at the ends 4c, 4d of the shoulder straps 4. Further, the fixed ends 4a, 4b are—not shown in FIG. 3a—sewed to the daysack 10, so that their position relative to the daysack 10 is fixed.

(23) In an embodiment the shoulders straps 4 are completely detachable from the daysack 10. This allows e.g. a separate cleaning and washing, respectively, of the straps. Further, specially configured shoulder straps can be provided adapted to individually user's need. This for example could be shoulder straps specially adapted with regard to the width in the area of contact with the user or with regard to specially padded straps.

(24) FIG. 3a shows the daysack 10 completely outside the compartment 2 of the lid 1 in the second state S2. Thus, the transformation by turning the inside out of the lid 1 is completed, wherein now it is noticed that the lid 1 and its compartment 2, respectively, comprise a totally different form and shape, respectively, as well as a totally different size comparing the first and the second state S1, S2 of the lid 1 and the standalone daysack 10, respectively.

(25) Further, the daysack comprises a main part 5 and a lid part 6. The main part 5 was stored in the lid's compartment 2, more precisely, in section 3 in a folded condition (see e.g. FIG. 2b or 2c). In FIG. 3a the main part 5 is in an unfolded condition in which the daysack 10 and its main part, respectively, has a baggy-like shape. In this unfolded condition the standalone daysack 10 is independently usable from the backpack as a standalone rucksack and daypack, respectively.

(26) Further, the lid part 6 is the compartment 2 in the second state S2. This means that in the second state S2 the compartment 2 was transformed to the lid part 6 by turning the inside of the compartment 2 out. By this, in the second state S2 an inverted compartment 2 is obtained which forms part, namely the lid part 6, of the daysack 10 in the second state S2.

(27) Thus, the daysack 10 comprises a main part 5 and a lid part 6 or in other words a main compartment 5 which forms the main part 5 of the standalone daysack 10 and an inverted compartment 2 which forms the lid part 6.

(28) Now referring to FIG. 3b in which the daysack 10 of FIG. 3b in the second state S2 is shown. FIG. 3b is mainly similar to FIG. 3a, wherein the inside of the daysack 10 can be seen in part. All explanations made for FIG. 3a also apply for FIG. 3b. Further, besides the side release buckles 31 and the female counterpart 31a, respectively, a connecting means 14 is depicted.

(29) The two compartments, namely main compartment 5 and inverted compartment 2 can be separated and connected by the connecting means such which is realized in this embodiment as a zipper 14. This separation and connection, respectively, is no demounting or mounting of one part from or to another, but it is an enlarging or diminishing with regard to the size within the daysack 10.

(30) Then, e.g. if the zipper 14 is closed the daysack 10 comprises in its interior two separate compartments (main and inverted compartment). Thus, equipment filled in the main compartment 5 cannot arrive in the inverted compartment 2 and lid part 6, respectively. Also the other way round, equipment filled in the inverted compartment 2 cannot arrive in the main compartment and the main part 5, respectively.

(31) However, if both compartments (main 5 and inverted compartment 2) are connected by the connecting means 14 the volume of one compartment is increased by the volume of the other compartment, and thus, the internal volume of the standalone daysack 10 is in the condition in which the largest objects can be carried.

(32) In other words, the main compartment 5 of the standalone daysack 10 comprises a portion which is shared with the inverted compartment 2 of the lid 1 in the second state S2. This shared portion and shared bottom, respectively, ideally comprises the connecting means 14 and the zipper, respectively. By opening the zipper 14 the volume of the main compartment 5 of the standalone daysack 10 and the volume of the inverted compartment 2 of the lid 1 are connected such that the standalone daysack 10 has one large compartment. Thus, by opening the zipper 14 the two volumes of the compartments 2, 5 are connected to one volume. Using the zipper 14 depends on the user's preference to have one big volume or two smaller volumes and compartments, respectively.

(33) In the second state S2 also the opening 7 or more precisely the also inverted opening 7 is shown in FIGS. 3a and 3b. This inverted opening 7 is also closable and openable as the non-inverted opening 7 as shown in FIGS. 2a to 2c. Thus, the compartment 2 as well as the inverted compartment 2 and the lid part 6, respectively, are accessible through the opening 7.

(34) The zipper 7a installed for opening and closing the compartment 2 functions in the same way in both states S1, S2. Hence, the zipper 7a is usable in the first and second state to open and lock the opening 7. In this context, it is noticed that instead of the zipper also snap buttons can be used for which it also doesn't matter whether they are used in an inverted or non-inverted state of the compartment 2.

(35) While the opening 7 having the zipper 7a is located at the bottom of FIGS. 3a, 3b a further opening of the standalone daysack 10 is located mainly opposite at the top of FIGS. 3a, 3b in an open condition. Thus, the standalone daysack 10 has the further opening 11 which gives access to the interior. This further opening 11 comprises a pull cord 12 and a cord lock 13 by which the further opening 11 is openable and closable. Such a construction is lightweight, easy and reliable.

(36) The pull cord 12 is guided in a channel 12a formed by the main part 5 of the standalone daysack 10 at the opening 11. The channel circulates around the opening 11, wherein the channel 12a comprises a gap 12b interrupting the channel. At the gap the cord lock 13 is installed. The pull cord is guided through the channel 12a as well as through the cord lock 13. Thus, the pull cord forms a closed loop, wherein the length and circumference, respectively, of the pull cord is variable by opening and closing the cord lock 13.

(37) By pulling the pull cord 12 in a direction away from the daysack 10, the further opening 11 of the standalone daysack 10 and its main part 5, respectively, is closed. Hence, the cord lock 13 arrests the loop's circumference of the cord lock 13. For releasing the further opening 11 of the standalone daysack 10 the cord lock has to be unlocked. By unlocking the circumference of the loop the further opening 11 of the standalone daysack 10 can be opened as now the loop's circumference can be increased by pulling the loop.

(38) Whereas in FIGS. 3a, 3b the opening 7 and the further opening 11 are in an open condition, wherein the standalone daysack 10 is in the second state S2, in FIG. 3c the daysack 10 comprises the opening 7 and the further opening 11 in a closed condition, wherein the standalone daysack 10 is still in the second state S2.

(39) Thus, in FIG. 3c in which the further opening 11 is closed the circumference of the pull cord 12 and the loop, respectively, is shorter than in comparison to the circumference shown in FIGS. 3a, 3b in which the further opening 11 is open.

(40) FIGS. 4a and 4b show the back of the standalone daysack 10. Here, the shoulder straps 4 are mounted to the standalone daysack 10. In FIG. 4a a pad 15 and its contour 15a, respectively, is shown.

(41) Such a pad 15 provides a convenient wearing comfort of the standalone daysack and it's outside, respectively, in particular at a contact surface with a user. The pad 15 which in the first state S1 is located within the compartment 2 of the lid 1 is in the second state S2 positioned on the outside of the inverted compartment 2. However, for providing an optimal wearing comfort, in particular at the back of the user contacting the standalone daysack 10 the pad 15 should be located at a predetermined position.

(42) This is realized by a hook and loop fastener 17 having a male 17b and a female part 17a. The male part 17b of the hook and loop fastener in the first state S1 is positioned at the inside of the compartment 2 and in the second state S2 it gets outside due to turning inside out of the compartment 2. The female part 17a of the hook and loop fastener 17 is located at the outside of the main part 5 of the standalone daysack 10 and thus is only accessible in the second state S2 in which the main part 5 of the daysack 10 is outside the compartment 2 due to inverting. Thus, after inverting the compartment 2 and the lid 1, respectively, the male 17b and female part 17a of the hook and loop fastener 17 can be connected so as to adjust the position of the pad 15.

(43) By connecting the male with the female part the pad 15 which is connected to the compartment 2 and the inverted compartment 2, respectively, arrives at a predetermined position at the back of the standalone daysack 10 so that a user's back can be optimally protected. Thus, protection as well as an optimal wearing comfort can be provided to the daysack's user.

(44) Summarizing the above, the pad 15 is held in position in the second state S2 of the lid 1 at the same side as the shoulder straps 4 by use of a the hook and loop fastener 17. By this, a predetermined position of the pad 15 in the second state S2 of the lid 1 is realized so that the pad 15 can protect e.g. the back of a user while wearing the daysack 10.
