DESCRIPTION OF THE PREFERRED EMBODIMENTS [061] Before explaining at least one embodiment in detail, it is to be understood that the subject matter is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The subject matter is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. In discussion of the various figures described herein below, like numbers refer to like parts. The drawings are generally not to scale. [062] For clarity, non-essential elements were omitted from some of the drawings. [063] The present subject matter provides a portable cloth holding device, comprising: a pouch configured to hold a cloth attached to a string; a cloth pulley inside the pouch for holding the cloth; and a string pulley inside the pouch for holding the string, wherein the cloth pulley and the string pulley allow pulling of the cloth and the string out of the pouch, and a self-returning of the cloth and the string back into the pouch. [064] Referring now to Fig. 1, schematically illustrating, according to an exemplary embodiment, a perspective view of a portable cloth holding device attached to a garment, or wearable accessory. For the sake of simplicity only, the portable cloth holding device 1 is occasionally termed hereinafter "device 1". As can be seen in Fig. 1, the device 1 comprises a pouch 12. According to one embodiment, the pouch 12 is configured to attach to a garment of a user. According to another embodiment, the pouch 12 is configured to attach to a wearable accessory of a user. In the embodiment shown in Fig. 1, the device 1 is attached to a belt 600. Thus, according to yet another embodiment, the pouch 12 is configured to attach to a belt 6of a user. It should be noted that the present subject matter is not limited to a belt 600 as an object to which the pouch 12 can be attached. Any type of garment, or wearable accessory, is under the scope of the present subject matter, for example, a shirt, trousers, pants, a backpack, as belt 600, as shown in Fig. 1, and the like. According to another embodiment, the pouch can also be used without attaching the pouch 12 to a a garment, or a wearable accessory. The pouch 12 can be held, for example, by a user’s hand, even though this embodiment is somewhat not comfortable. [065] According to one embodiment, the pouch 12 is configured to contain within the pouch a cloth 500, and a string 550 attached to the cloth 500. Fig. 1 shows the cloth 500 after the cloth 500 has been pulled out of the pouch 12, and a part of the string 550 that is attached to the cloth 500. The rest of the string 550 is within the pouch 12. [066] Any type of cloth 500 is under the scope of the present subject matter, for example, a towel, a cloth as used for wiping surfaces, a rag, a duster, a handkerchief, a napkin and the like. According to one embodiment, the cloth 500 is a towel. [067] According to one embodiment, shown in Fig. 1, the pouch 12 is closed and comprises an opening 124 configured to allow pulling the cloth 500 out of the pouch 12 and returning of the cloth 500 back into the pouch 12. This embodiment ensures protection of the cloth 5inside the pouch 12, for example against dirt, moisture and the like. Another advantage of this embodiment is related to the esthetic appearance of the device 1, in the sense that the cloth 500 11 is stored inside the pouch 12 and is not exposed and seen. According to this embodiment, the opening 124 is small and allows only passage of the cloth 500 and the string 550 therethrough. [068] Referring now to Figs. 2A-D schematically illustrating, according to an exemplary embodiment, a side see-through view of a portable cloth holding device, and four exemplary positions of a cloth and a string attached to the cloth, inside and out of a pouch of the portable cloth holding device. According to one embodiment, shown in Figs. 2A-D, the device comprises two pulleys inside the pouch 12 – a cloth pulley 132 configured to allow wrapping of the cloth 500 around the cloth pulley 132, and a string pulley 134 configured to allow wrapping of the string 550 around the string pulley 134. A detailed description of the cloth pulley 132 and the string pulley 134 is given in the following drawings. [069] Another embodiment, shown in Figs. 2A-D, is that the device 1 further comprises an axis 136 common to both the cloth pulley 132 and the string pulley 134, and both the cloth pulley 132 and the string pulley 134 are configured to rotate about the axis 136. [070] As mentioned above, the cloth 500 and the string 550 can be pulled out of the pouch and self-return back into the pouch 12. Thus, Figs. 2A-D show four exemplary positions of the cloth 12 and the string 550 attached to the cloth 500, inside and out of the pouch 12. [071] Fig. 2A shows the cloth 550 entirely inside the pouch 12. In this position, most of a length of the string 550 is wrapped around the string pulley 134 and most of the length of the cloth 550 is wrapped around the cloth pulley 132. As can be seen in Fi. 2A, a part of the string 550 that is not wrapped around the string pulley 134 lies between the string pulley 134 and an end of the cloth 500. In addition, a part of the cloth 500 that is not wrapped around the cloth pulley 132 lies between the cloth pulley 132 and the opening 124 of the pouch 12. This embodiment is important in order to allow pulling the cloth 500 out of the pouch 12 by a user. If the cloth 500 is entirely wrapped around the cloth pulley 132, inside the pouch 12, the user cannot reach the cloth 500 in order to pull the cloth 500 out of the pouch 12 through the opening 124. [072] According to one embodiment, in order to keep an edge of the cloth 500 accessible by the user, the cloth 500 comprises a stopper 510 at an edge of the cloth residing outside of the pouch 12 and configured to stop further movement of the cloth 500 into the pouch 12 through the opening 124, and allow access of a user to the cloth 500 in order to grasp the cloth 500, or 12 the stopper 510, and pull the cloth 500 out of the pouch 12. According to another embodiment, the stopper 510 is larger than the opening 124 of the pouch 12 and is positioned externally to the pouch 12. Thus, the stopper 510 prevents full entrance of the cloth 500 into the pouch 12. Any type of stopper 510 is under the scope of the present subject matter. According to one embodiment, the stopper 510 is a knot made at an edge of the cloth 500. As mentioned above, the size of the stopper 510 in a form of a knot in the towel is larger than the size of the opening 124 of the pouch 12. According to another embodiment, the stopper 510 is an object attached to an edge of the cloth 500. Any type of object used as a stopper 510 is under the scope of the present subject matter, for example a ring or an object having any other shape and size, given that the size of the object used as a stopper 510 is larger than the size of the opening 124 of the pouch 12. [073] The position shown in Fig. 2A is of a cloth 500 not in use. In this position the cloth 5resides entirely inside the pouch 12. In this position the cloth 500 is not seen, thus illustrating the asethetic apperance contributed by the device 1 of the presnt subject matter. In addition, when the cloth 500 resides inside the pouch 12 it is protected from dirt, moisture and the like. Furthermore, the embodiments described above contribute to the easiness of using the device 1. For example, the stopper 510 attached to the cloth 500 allows easy grasping and pulling of the cloth 500 out of the pouch 12. [074] Fig. 2B shows a cloth 550 partially out of the pouch 12. This position occures, for example, when a user grasps the stopper 510, or an edge of the cloth 500 that protrudes out of the opening 124 of the pouch 12, and pulls the cloth 500 out of the pouch 12, through the opening. [075] As a result of pulling the cloth 500 out of the pouch 12, the cloth pulley 132 rotates in a direction towards the opening 124, designated with arrow 902, and a part of the cloth 5leaves the cloth pulley 132 as the cloth 500 is pulled out of the pouch 12. Thus, according to one embodiment, the cloth pulley 132 is configured to rotate toward the opening 124 when the cloth 500 is pulled out of the pouch 12 and leaves the cloth pulley 132. [076] Fig. 2C shows a cloth 500 further pulled out of the pouch 12. At this position, the entire cloth 500 is released from the cloth pulley 132, and now as the cloth 500 is further pulled out of the pouch 12, the string 550 is released from the string pulley 134 and is dragged by the 13 pulled cloth 500. At this position, connection point 555 between the string 550 and the cloth 500 is seen. As the string 550 is pulled out from the string pulley 134, the string pulley 1rotates in a direction 902. Thus, according to this embodiment, when the cloth 500 is pulled out of the pouch 12 and entirely leaves the cloth pulley 132, the string 550 is configured to be dragged by the pulled cloth 500, and as the string 500 is dragged out and leaves the string pulley 134, the string pulley 134 is configured to rotate toward the opening 124. [077] Fig. 2D shows the cloth 500 entirely pulled out of the pouch 12, as well as part of the string 550. At this position, the connection point 555 between the cloth 500 and the string 5is seen out of the pouch. At this position, the string 550 is further released from the string pulley 134, and as earlier described, as the string 550 is pulled out of the pouch 12, the string pulley 134 rotates toward the opening 124 of the pouch 12, in direction 902. [078] According to one embodiment, when there is a need to return the cloth 500 back into the pouch 12, for example after the cloth 500 is used for any purpose it is made for, all a user has to do is to release the pulling force that is exerted by him on the cloth 500. As a result, the string pulley 134 now self rotates away from the opening 124 of the poucg 12, in a direction designated by arrow 904, which is opposite to direction 902. Now the series of positions, illustrated in Figs. 2A-D, goes backwards, from the position shown in Fig. 2D back to the position shown in Fig. 2A. [079] At this series of positions, Fig. 2D shows the starting point of the return of the cloth 500 back into the pouch 12, when the pulling force that is exerted on the cloth 500 is released, and the string pulley 134 starts to move in direction 904. As a result, the string 550 starts to wrap around the string pulley 134. Thus, according to this embodiment, when a pulling force on the cloth 500 is released, the string pulley 134 is configured to self rotate away from the opening 124, and as a result the string 550 wraps around the string pulley 134. [080] Fig. 2C shows a position in which most of the string 550 has returned into the pouch 12, and wrapped around the string pulley 134, while a part of the cloth 500 has also returned into the pouch. This is achieved due to the self-rotation of the string pulley 134 in direction 904. [081] When the string 550 is fully wrapped around the string pulley 134, and the connection point 555 between the cloth 500 and the string 550 is close to the string pulley 134, the cloth 14 500 starts to wrap around the cloth pulley 134, as the cloth pulley 132 self-rotates in direction 904, as shown in Fig. 2B. Thus, according to this embodiment, when the string 500 fully wraps around the string pulley 134, the cloth pulley 132 self-rotates away from the opening 124, in direction 904, and the cloth 500 wraps around the cloth pulley 132. [082] The return of the cloth 500 into the pouch 12, and the wrapping of the cloth 500 around the cloth pulley 132, continue until the stopper 510 reaches the opening 124 of the pouch 12, as shown in Fig. 2A. At this position, the wrapping of the cloth 500 around the cloth pulley 132 stops because the stopper 510 cannot pass through the opening 124 and enter into the pouch 12. At this position, also the rotation of the cloth pulley 132 stops. [083] Referring now to Figs. 3A-D, schematically illustrating, according to an exemplary embodiment, a top view (Figs. 3A and 3B), a side view (Fig. 3C) and a perspective view (Fig. 3D) of a cloth pulley and a string pulley. As can be seen in Figs. 3C and 3D, the cloth pulley 132 and the string pulley 134 have a common axis 136. In other words, the cloth pulley 1and the string pulley 134 are configured to rotate about the same axis 136. [084] Fig. 3A-D show a cloth pulley 132 that is larger than the string pulley 134. It should be noted that this is only an exemplary embodiment that is shown in Figs. 3A-D. According to another embodiment, the string pulley 134 is larger than the cloth pulley 132. According to yet another embodiment, the cloth pulley 132 and the string pulley 134 are similar in size. [085] According to one embodiment, only the cloth pulley 132, or only the string pulley 134, or both the cloth pulley 132 and the string pulley 134, comprise a slot on the circumference of the pulley. The cloth pulley 132 can comprises a cloth slot 1325 and the string pulley 134 can comprise a string slot 1345. It should be noted that the embodiment shown in Figs. 3A, 3B and 3D, of the cloth pulley 132 comprising a cloth slot 1325 and the string pulley 134 comprising a string slot 1345 is only exemplary, and should not be considered as limiting the scope of the present subject matter. Only the cloth pulley 132 can comprise a cloth slot 1325, or only the string pulley 134 can comprise a string slot 1345, or none of the cloth pulley 132 and the string pulley 134 comprises a slot. [086] An aim of the cloth slot 1325 is to accommodate the cloth 500 that is wrapped around the cloth pulley 132. Another aim of the cloth slot 1325 is to prevent falling of the cloth 500 off the cloth pulley 132 – an event that can cause entangling of the cloth 500 inside the pouch and impairment of a smooth operation of the cloth pulley 132 and the string pulley 134. [087] An aim of the string slot 1345 is to accommodate the string 550 that is wrapped around the string pulley 134. Another aim of the string slot 1345 is to prevent falling of the string 5off the string pulley 134 – an event that can cause entangling of the string 550 inside the pouch and impairment of a smooth operation of the cloth pulley 132 and the string pulley 134. [088] Referring now to Figs. 4A-B, schematically illustrating, according to an exemplary embodiment, a transparent side view of a string pulley and a cloth pulley, respectively. According to one embodiment, shown in Fig. 4A, a string elastic element 135 is attached to the string pulley 134. According to another embodiment, the string elastic element 135 has a relaxed state when the string 550 is wrapped around the string pulley 134, and a stretched state when the string 550 is pulled out of the string pulley 134. Thus, the string elastic element 1is configured to stretch when the string pulley 134 rotates toward the opening 124 in direction 902, when the string 550 is pulled out and is released from the string pulley 134 (see also Fig. 2D). When the pulling power on the string 550 is released, the string elastic element 135 is configured to return to the relaxed state. When the string elastic element 135 returns to the relaxed state it causes the string pulley 134 to rotate away from the opening 124 in direction 904 (see also Fig. 2D). As a result, the string 550 wraps around the string pulley 134. This is the mechanism by which the string 550 can return to be wrapped around the string pulley 134, thereby returning the string 550 back into the pouch 12, while dragging the cloth 500 also toward and into the pouch 12. [089] According to another embodiment, shown in Fig. 4B, a cloth elastic element 133 is attached to the cloth pulley 132. According to another embodiment, the cloth elastic element 133 has a relaxed state when the cloth 500 is wrapped around the cloth pulley 132, and a stretched state when the cloth 500 is pulled out of the cloth pulley 132. Thus, the cloth elastic element 133 is configured to stretch when the cloth pulley 132 rotates toward the opening 1in direction 902, when the cloth 500 is pulled out and is released from the cloth pulley 132 (see also Figs. 2B-C). When the pulling power on the cloth 500 is released, the cloth elastic element 133 is configured to return to the relaxed state. When the cloth elastic element 133 returns to the relaxed state it causes the cloth pulley 132 to rotate away from the opening 124 in direction 904 (see also Figs. 2B-C). As a result, the cloth 500 wraps around the cloth pulley 132. This is 16 the mechanism by which the cloth 500 can return to be wrapped around the cloth pulley 132, when the cloth 500 returns back into the pouch 12. [090] The string elastic element 135 can have any shape and size. For example, the string elastic element 135 can have a shape of a liner spring. In another example, shown in Fig. 4A, the string elastic element 135 has a shape of a spiral torsion spring. It should be emphasized that the embodiment of the string elastic element 135 having a shape of a spiral torsion spring, as shown in Fig. 4A, is only exemplary, and should not be considered as limiting the scope of the present subject matter. The string elastic element 135 can have any shape and size. [091] Similarly, the cloth elastic element 133 can have any shape and size. For example, the cloth elastic element 133 can have a shape of a liner spring. In another example, shown in Fig. 4B, the cloth elastic element 133 has a shape of a spiral torsion spring. It should be emphasized that the embodiment of the cloth elastic element 133 having a shape of a spiral torsion spring, as shown in Fig. 4B, is only exemplary, and should not be considered as limiting the scope of the present subject matter. The cloth elastic element 133 can have any shape and size. [092] The string elastic element 135 can be positioned in relation to the string pulley 134 at any position. For example, the string elastic element 135 is positioned aside the string pulley 134. According to the exemplary embodiment, shown in Fig. 4A, the string elastic element 1is positioned inside the string pulley 134. Thus, according to this embodiment, the string pulley 134 is hollow, and the string elastic element 135 resides inside the string pulley 134. [093] The cloth elastic element 133 can be positioned in relation to the cloth pulley 132 at any position. For example, the cloth elastic element 133 is positioned aside the cloth pulley 132. According to the exemplary embodiment, shown in Fig. 4B, the cloth elastic element 1is positioned inside the cloth pulley 132. Thus, according to this embodiment, the cloth pulley 132 is hollow, and the cloth elastic element 133 resides inside the cloth pulley 132. [094] Returning now to Fig. 3A. According to one embodiment, the cloth pulley 132 and the string pulley 134 are permanently connected one to each other, as can be seen in Fig. 3A, where it is shown that the cloth pulley 132 and the string pulley 134 are connected side to side. Thus, when the cloth pulley 132 rotates, for example as a result of pulling the cloth 500 out of the cloth pulley 132, as described above, the string pulley 134 rotates together with the cloth pulley 132; or vice versa, when the string pulley 134 rotates, for example as a result of pulling the 17 string 550 out of the sting pulley 134, as described above, the cloth pulley 132 rotates together with the string pulley 134. [095] Returning now to Fig. 3B. According to another embodiment, the cloth pulley 132 and the string pulley 134 are permanently separated one from the other, as can be seen in Fig. 3B, where it is shown that there is a gap 137 between the cloth pulley 132 and the string pulley 134. Fig. 3B shows a gap 137 between the cloth pulley 132 and the string pulley 134 in order to illustrate the lack of connection between the cloth pulley 132 and the string pulley 134. For example, the cloth pulley 132 and the string pulley 134 can reside side by side, as shown in Fig. 3A, but the cloth pulley 132 is not connected to the string pulley. Thus, when the cloth pulley 132 rotates, for example as a result of pulling the cloth 500 out of the cloth pulley 132, as described above, the string pulley 134 does not necessarily rotate together with the cloth pulley 132; or vice versa, when the string pulley 134 rotates, for example as a result of pulling the string 550 out of the sting pulley 134, as described above, the cloth pulley 132 does not necessarily rotate together with the string pulley 134. [096] Referring now to Figs. 5A-B, schematically illustrating, according to an exemplary embodiment, a top view of a cloth pulley and a string and a connector in a form of a bolt. According to one embodiment, the cloth pulley 132 and the string pulley 134 are separated and are configured to transiently connect one to each other. As can be seen in Figs. 5A-B, the cloth pulley 132 and the string pulley 134 are not connected, as was shown previously in Fig. 3B and described in the previous paragraph. Howver, according to one embodiment, the cloth pulley 132 and the string pulley 134 further comprise a connector 140 configured to transiently connect the cloth pulley 132 and the string pulley 134. Accordiong to another embodiment, the connector 140 has two positions, a connected position, shown in Fig. 5A, and a disconnected position, shown in Fig. 5B. [097] Any type of connector 140 is under the scope of the present subject matter. The exemplary connector 140 shown in Fig. 5A-B is a bolt 142. According to one embodiment, the bolt 142 resides in the cloth pulley 132 and is configured to transiently and partially move into the string pulley 134. When the bolt 142 is only inside the cloth pulley 132, as shown in Fig. 5B, the cloth pulley 132 is disconnected from the string pulley 134, and the cloth pulley 1and the string pulley 134 can rotate independently. When the bolt 142 partially moves into the string pulley 134, as shown in Fig. 5A, the cloth pulley 132 is connected with the string pulley 134, and both the cloth pulley 132 and the string pulley 134 can rotate together. 18 id="p-98" id="p-98"

[098] It should be noted that the positioning of the bolt 142 can be opposite compared to the positioning shown in Figs. 5A-B. In any case, the functioning of the bolt 142 and its outcome in terms of connection and disconnection of the cloth pulley 132 and the string pulley 134 are similar in both positionings of the bolt 142. [099] Thus, according to an additional embodiment, the bolt 142 resides in the string pulley 134 and is configured to transiently and patially move into the cloth pulley 132. When the bolt 142 is only inside the string pulley 134, the string pulley 134 is disconnected from the cloth pulley 132, and the string pulley 134 and the cloth pulley 132 can rotate independently. When the bolt 142 partially moves into the cloth pulley 132 the string pulley 134 is connected with the cloth pulley 132, and both the string pulley 134 and the cloth pulley 132 can rotate together. [100] According to one embodiment, the connector 140 is configured to be in the connected position as long as the cloth 500 is wrapped around the cloth pulley 132, and be in the disconnected position as long as the cloth 500 is released from the cloth pulley 132. Following Figs. 6A-B illustrate a connector 140 that is configured to function according to this embodiment. [101] Referring now to Figs. 6A-B, schematically illustrating, according to an exemplary embodiment, a top view of a cloth pulley and a string and a connector functioning magnetically. Figs. 6A-B illustrate a connector 140 configured to connect the cloth pulley 132 with the string pulley 134 as long as the cloth 500 is wrapped around the cloth pulley 132, and disconnect the cloth pulley 132 from the string pulley 134 when the cloth 500 is removed from the cloth pulley 132. [102] According to an additional embodiment, the connector 140 is a bolt 142 that resides in the string pulley 143, as described above. and is configured to transiently and partially move into the cloth pulley 132. In addition, the connector 140 further comprises a bolt elastic element 144 attached with one side to the bolt 142 and fixed to the string pulley 134 with another side. The bolt elastic element 144 is configured to pull the bolt 142 away from the cloth pulley 1in a first force. The direction of the force exerted by the bolt elastic element 144 on the bolt 142 is designated with arrow 802 in Figs. 6A-B, and the level of the force exerted by the bolt elastic element 144 is designated by the length of arrow 802. 19 id="p-103" id="p-103"

[103] In addition, the connector 140 further comprises a magnet 146 positioned at the connection point 555 between the cloth 500 and the string 550. According to this embodiment, the bolt 142 is made of a material that is attractable by a magnet. Any material attractable by a magnet is under the scope of the present subject matter, for example, but not limited to, iron, cobalt, steel, nickel, manganese, gadolinium, lodestone and the like. [104] As can be seen in Fig. 6A, when the cloth 500 is wrapped around the cloth pulley 132, the magnet 146 is positioned in a vicinity of the bolt 142. Since the bolt 142 is attractable to a magnet, a second pulling force is exerted by the magnet 146 on the bolt 142 toward the cloth pulley 132. The direction of the second pulling force exerted by the magnet 146 on the bolt 1is designated by the arrow 804, and the level of the second force exerted by the magnet 146 on the bolt 142 is designated by the length of arrow 804. As can be seen in Fig. 6A, the magnet second pulling force 804 of the magnet 146 is larger than the bolt first pulling force 802 of the bolt elastic element 144. As a result, the magnet pulling force 804 overcomes the bolt pulling force 802, and thus the bolt 142 is pulled toward the cloth pulley 132, partially inserted into the cloth pulley 132 and connects the string pulley 134 with the cloth pulley 132. [105] As can be seen in Fig. 6B, when the cloth 500 starts to be released from the cloth pulley 132, the magnet 146 moves away from the bolt 142. As a result, the only force that is exereted on the bolt 142 is the bolt pulling force 802, which causes the bolt 142 to be pushed away from the cloth pulley 132, thus disconnecting the string pulley 134 from the cloth pulley 132. [106] A result of the embodiment shown in Figs. 6A-B, when the cloth 500 is pulled out but is still wrapped around the cloth pulley 132, the cloth pulley 132 and the string pulley 1rotate together, because they are connected. However, when the cloth 500 is released from the cloth pulley 132, but the string 550 is still wrapped around the string pulley 134, when the cloth 500 continue to be pulled out, only the string pulley 134 rotates as the string 550 is removed from the string pullet 134. [107] A similar situation occurs when the string 550 and the cloth 500 return back into the pouch 12. When the string 550 returns to be wrapped on the string pulley 134, the string pulley 134 and the cloth pulley 132 are disconnected and only the string pulley 134 rotates. However, when the cloth 500 starts to return to be wrapped around the cloth pulley 132, the cloth pulley 132 and the string pulley 134 become connected, and as the cloth 500 is being wrapped around the cloth pulley 132, the cloth pulley 132 and the string pulley 134 rotate together. An advantage of the mechanism is that it prevents interwinding of the cloth 500 and the string 5when the cloth 500 is pulled out of the pouch 12, or returns back into the pouch 12. [108] Based on the embodiments shown in Figs. 6A-B, and their description given above, the present subject matter provides a method for controlling a function of a cloth pulley 132 and a string pulley 134 of a portable cloth holding device, the method comprising: providing the device 1 shown in Figs. 6A-B, including the embodiments described above; as shown in Fig. 6A, when the cloth 500 is wrapped around the cloth pulley 132, positioning the magnet 146 in a vicinity of the bolt 142, thus attracting the bolt 142 towards the cloth pulley 132 in a force (arrow 804) that is greater than the force of pulling the bolt 1toward the string pulley 134 by the bolt elastic element 144 (arrow 802), thereby partially inserting the bolt 142 into the cloth pulley 132 and connecting the string pulley 134 with the cloth pulley 134; pulling the cloth 500 out of the pouch 12, thereby causing the cloth 500 to be released from the cloth pulley 132 as the cloth pulley 132 rotates toward the opening 124 of the pouch 12 (arrow 902), as shown in Fig. 2B; when the entire cloth 500 is released from the cloth pulley 132, as shown in Fig. 2C, further pulling of the cloth 500 out of the pouch 12 causes the magnet 146 to move away from the bolt 142, thereby releasing the pulling force of the magnet 146 from the bolt 142 and causing the bolt 142 to be pulled into the string pulley 134 by the pulling force of the bolt elastic element 144 (arrow 802), thereby disconnecting the string pulley 134 from the cloth pulley 132, as shown in Fig. 6B further pulling of the cloth 500 out of the pouch 12, causes the string 550 to be released from the string pulley 134 as only the string pulley rotates toward the opening 124 of the pouch 12 (arrow 902), as shown in Fig. 2D; when desired, releasing a pulling power exerted on the cloth 500 after pulling the cloth 500 out of the pouch 12; self-rotating of only the string pulley 134 in a direction away from the opening 124 (arrow 904), thereby wrapping the string 550 around the string pulley 134, wherein the string pulley 134 and the cloth pulley 132 are disconnected; as shown in Fig. 6A, when the magnet 146 reaches a vicinity of the bolt 142, a pulling power of the magnet 146 on the bolt 142 toward the cloth pulley 132 (arrow 804) overcomes a pulling power of the bolt elastic element 144 on the bolt 142 toward the string 21 pulley 134 (arrow 802), thereby partially inserting the bolt 142 into the cloth pulley 132 and connecting the string pulley 134 with the cloth pulley 132; and self-rotating of the cloth pulley 132 with the string pulley 134, thereby wrapping the cloth 500 around the cloth pulley 132. [109] Referring now to Fig. 7, schematically illustrating, according to an exemplary embodiment, a transparent top view of a string pulley positioned inside a cloth pulley. In Fig. 7, the cloth pulley 132 is shown transparent, thus allowing to see components that are inside the cloth pulley 132. According to one embodiment, shown in Fig. 7, the string pulley 134 is positioned inside the cloth pulley 132. According to another embodiment, the cloth elastic element 133 is positioned also inside the cloth pulley 132, aside the string pulley 134. According to yet another embodiment, the string elastic element 135 is positioned inside the cloth pulley 132, aside the string pulley 134, as can be seen in Fig. 7. According to still another embodiment, the string elastic element 135 is positioned inside the string pulley 134, as shown for example in Fig. 4A. According to a further embodiment, the cloth pulley 132 comprises a hole 137 on a circumference of the cloth pulley 132, the hole 137 is configured to allow passage of the string 550 therethrough. [110] Thus, according to the embodiment shown in Fig. 7, and in line with the previous descriptions, the string 550 is wrapped around the string pulley 134 and protrudes outside the cloth pulley 132 through the hole 137. In addition, the cloth 500, that is connected to the string 550, is wrapped around the cloth pulley 132. [111] According to the exemplary embodiments shown in Figs. 5A-B and 6A-B and in line with Figs. 2A-D, when the cloth 500 is pulled out of the pouch 12, the string pulley 134 is connected to the cloth pulley 132. Therefore, as the cloth 500 is pulled out the cloth string 1rotates in direction 902, as shown, for example, in Fig. 2B. As a result, only the cloth elastic element 133 is stretched as long as the cloth 500 is still wrapped around the cloth pulley 1and pulled outside. At this stage, when the cloth 500 is pulled outside but still wrapped around the cloth pulley 132, the cloth pulley 132 rotates in direction 902, but the string elastic element 135 is not stretched. However, when the cloth 500 is removed from the cloth pulley 132, the cloth pulley 132 is disconnected from the string pulley 143, and locked. As a result, the cloth pulley 132 cannot rotate at either direction. Since the string pulley 134 is now disconnected from the cloth pulley 132, the string pulley now rotates in direction 902 as long as the string 22 550 is pulled out with the cloth 500. At this stage, the string elastic element 135 is stretched, as the string 550 leaves the string pulley 134 and the string pulley 134 rotates in direction 902. [112] As described above, in relation to Figs. 2A-D, when the pulling force that is exerted on the cloth 500 is released, the string elastic element 135 returns to the relaxed state. As a result, the string pulley 134 rotates in direction 904 and the string is wrapped around the string pulley 134. At the stage, only the string pulley 134 rotates, while the cloth pulley 132 is disconnected from the string pulley134 and locked. Namely, the cloth pulley 132 does not rotate when the string pulley 134 rotates, even though the cloth elastic element 133 tends to return to the relaxed state. When the cloth 500 reaches the cloth pulley 132, the lock of the cloth pulley 132 is released, and the cloth pulley 132 is connected to the string pulley 134. After the lock of the cloth pulley 132 is released, the cloth pulley rotates in direction 904 because the cloth elastic element 133 returns to the relaxed state. As a result, the cloth 500 wraps around the cloth pulley 132. [113] In other words, according to one embodiment that is related to the embodiment shown in Fig. 7, when the cloth 500 is pulled out of the pouch 12, the pulling force causes the cloth pulley 132 to rotate toward the opening 124 of the pouch12, and as long as the cloth 500 is still wrapped around the cloth pulley 132, the cloth elastic element 133 stretches, the string pulley 134 does not rotate and the string elastic element 135 remains at a relaxed state and does not stretch. [114] According to another embodiment that is related to the embodiment shown in Fig. 7, when the cloth 500 is pulled out of the pouch 12 and is released from the cloth pulley 132, the string 550 is pulled out following the cloth 500, and the pulling force causes the string pulley 134 to rotate toward the opening 124 of the pouch 12, and the string elastic element 1stretches, while the cloth pulley 132 does not rotate and the cloth elastic element 133 remains stretched. [115] According to yet another embodiment that is related to the embodiment shown in Fig. 7, when the pulling force on the cloth 500 is released, the string elastic element 135 returns to the relaxed state, thereby causing the string pulley 134 to self-rotate away from the opening 124 of the pouch 12, and causing the string 550 to wrap the string pulley 134, while the cloth pulley 132 does not rotate and the cloth elastic element 133 remains stretched. 23 id="p-116" id="p-116"

[116] According to still another embodiment that is related to the embodiment shown in Fig. 7, when the string 550 fully wraps the string pulley 134, the cloth elastic element 133 returns to the relaxed state, thereby causing the cloth pulley 132 to self-rotate away from the opening 124 of the pouch 12, and causing to cloth 500 to wrap the cloth pulley 134, while the string pulley 134 does not rotate and the string elastic element 134 remains in the relaxed state. [117] Referring now to Figs. 8A-B, schematically illustrating, according to an exemplary embodiment, a side view of a cloth holder at an edge of a string in a closed state and an open state, respectively. According to the embodiment shown in Figs. 8A-B, the device 1 further comprises a cloth holder 570 at the edge of the string 550 that is configured to attach to the cloth 500. In other words, the cloth holder 570 is positioned at the connection point 5between the string 550 and the cloth 500. According to another embodiment, the cloth holder 570 is configured to hold the cloth 500, thereby attaching the cloth 500 to the string 550. [118] As seen in Fig. 8A, the cloth holder 570 has a closed state, in which the cloth holder 570 is configured to hold the cloth 500, thereby attaching the cloth 500 to the string 550 at the connection point 555. At the closed state, the cloth holder 570 is smaller than the opening 1of the pouch 12, or is similar in size to the opening 124 of the pouch 12. Therefore, when the cloth holder 570 at the closed state holds the cloth 500, the cloth holder 570 can pass through the opening 124 of the pouch 12 when the cloth 500 and the string 550 are pulled out of the pouch 12, and when the cloth 500 and the string 550 self-return back into the pouch 12. [119] As can be seen in Fig 8B, the cloth holder 570 has an open state, in which the cloth holder 570 does not hold the cloth 500, and the cloth 500 is released, or de-attached from the string 550. At the open state, the cloth holder 570 is cannot pass through the opening 124 of the pouch 12 because it is larger than the opening 124 of the pouch. Therefore, when the cloth holder 570 at the open state does not hold the cloth 500, the cloth holder 570 cannot pass through the opening 124 of the pouch 12, for example when the string 550 self-returns back into the pouch 12. [120] In other words, according to one embodiment, the cloth holder 570 has an open state that is configured to release and not hold the cloth 500, and a closed state configured to hold the cloth 500. According to another embodiment, the cloth holder 570 at the open state is configured not to pass through the opening 124, and the cloth holder 570 at the closed state is configured to pass through the opening 124. 24 id="p-121" id="p-121"

[121] An advantage of the cloth holder 570 is to allow a user to disconnect the cloth 500 from the string 550, for example in order to replace a cloth 500, for example a used, or dirty cloth 500, with another cloth 500, for example a new, or clean, or fresh cloth 500. Thus, when a user wishes to replace a cloth 500 with another cloth 500, the user brings the cloth holder 570 to the open state and releases the cloth 500 (Fig. 8B), and then connects the other cloth 500 to the string 550 by bringing the cloth holder 570 back to the closed state over the cloth 500 (Fig. 8A). [122] Another advantage of the cloth holder 570 relates to the difference in size of the cloth holder 570 between the closed state and the open state. At the closed state, shown in Fig. 8A, the cloth holder 570 is smaller than the opening 124 of the pouch 12. Therefore, when the cloth 500 is attached to the string 550 by the cloth holder 570, the cloth holder 570 can pass through the opening 124 when the cloth 500 and the string 550 are pulled out of the pouch 12, and when the cloth 500 and the string 550 self-return back into the pouch 12. However, when the cloth 500 is released from the cloth holder 570, the cloth holder 570 is at the open state, shown in Fig. 8B, in which the cloth holder 570 is larger than the opening 124 of the pouch 12. Therefore, when a user pulls the cloth 500 and the string 550 out of the pouch 12, and the user releases the cloth 500, the string 550 tends to self-return back into the pouch 12 through the opening 124, according to embodiments described above. If there was no cloth holder 570, or if the open state of the cloth holder 570 was smaller than the opening 124, then the string 550 would fully self-return back into the pouch 12, and there might be a trouble to reach the edge of the string 550 for attaching to it the cloth 500. However, the open state of the cloth holder 570 does not allow full self-return of the string 550 back into the pouch 12, because the cloth holder 5at the open state is larger than the opening 124 of the pouch 12, and when after releasing the cloth 500 the string 550 self-returns back into the pouch 12, the cloth holder 570 at the open state is stuck at the opening 124. This allows easy access to the cloth holder 570 and easy grasping of another cloth 500 by the cloth holder 570. [123] It is appreciated that certain features of the subject matter, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the subject matter, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub combination. id="p-124" id="p-124"

[124] Although the subject matter has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
