Thus, the terms used in the specification should be understood not as simple names but based on the meaning of the terms and the overall description of the disclosure.
[0049] Throughout the specification, when a portion includes an element, another element may be further included, rather than excluding the existence of the other element, unless otherwise described.
[0050] Hereinafter, the present disclosure will be described more fully with reference to the accompanying drawings, in which embodiments of the disclosure are shown.
[0051] FIGS. 2 to 19 illustrate various embodiments of a hanger 100 for preventing the reverse flow of cloth. Referring to FIGS. 2 to 19, the hanger 100 may include: a body 10; a pair of supports 20 and 20a extending from the body 10, being apart from each other, and forming a gripping portion 50 that houses cloth 80 secured between the supports 20 and 20a in a forward direction A; a hanging pressure adjusting piece 30; hanging pressure adjusting piece projections 70; and a reverse flow preventing piece 40. The hanging pressure adjusting piece 30 extends from at least one of the body 10 and the supports 20 and 20a. The reverse flow preventing piece 40 obliquely extends toward the body 10 from one of the supports 20 and 20a and the hanging pressure adjusting piece 30. An extending end of the reverse flow preventing piece 40 elastically faces the other one of the supports 20 and 20a and the hanging pressure adjusting piece 30 and secures the cloth 80 therebetween. A surface of the cloth 80 housed in the gripping portion 50 is folded and hung on the extending end of the reverse flow preventing piece 40 to prevent the cloth 80 from moving in a reverse direction B that is opposite to the forward direction A. The hanging pressure adjusting piece projections 70 are formed on at least one of the body and the supports 20 and 20a so that the hanging pressure adjusting piece 30 may be hung on any one of the hanging pressure adjusting piece projections 70. As the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70, elasticity of the reverse flow preventing piece 40 may be adjusted.
[0052] The hanging pressure adjusting piece 30 may extend from one of the supports 20 and 20a, and the reverse flow preventing piece 40 may extend from the hanging pressure adjusting piece 30 and elastically face the other one of the supports 20 and 20a. The hanging pressure adjusting piece projections 70 may be formed on at least one of the body 10 and the support to which the hanging pressure adjusting piece 30 is connected.
[0053] FIG. 2 is a perspective view of the hanger according to the first embodiment, and FIG. 3 is a front view of FIG. 2. Referring to FIG. 2, the hanger 100 may include the body 10, two supports 20 and 20a connected to the body 10 and forming the gripping portion 50 in which cloth is secured, the hanging pressure adjusting piece 30 extending from one of the supports 20 and 20a, one or more hanging pressure adjusting piece projections 70 formed on the body 10 to have the hanging pressure adjusting piece 30 hung thereon, and the reverse flow preventing piece 40.
[0054] Ends of the supports 20 and 20a are apart from each other and respectively connected to the body 10, and the other ends of the supports 20 and 20a elongate. The gripping portion 50 securing the cloth is formed between the supports 20 and 20a. An entry portion 60 through which the cloth is inserted is formed between the other ends of the supports 20 and 20a. The end of the hanging pressure adjusting piece 30 may be connected to one of the supports 20 and 20a which form the gripping portion 50, for example, a distal end of the support 20a, and the other end of the hanging pressure adjusting piece 30 may extend towards the body 10. One or more, for example, three hanging pressure adjusting piece projections 70 may be formed on the body 10. FIG. 2 illustrates that the other end of the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70.
[0055] The end of the reverse flow preventing piece 40 is connected to one side of the hanging pressure adjusting piece 30 which is connected to the support 20a, and the other end of the reverse flow preventing piece 40 obliquely extends towards the body 10. The reverse flow preventing piece 40 does not prevent the cloth from flowing from the entry portion 60 to the body 10, that is, allows the flow of the cloth, and has a function of preventing the cloth from flowing from the body 10 to the entry portion 60. The hanging pressure adjusting piece 30 adjusts a location or a gradient of the reverse flow preventing piece 40 depending on a thickness of the cloth and makes the reverse flow preventing piece 40 easily perform the function.
[0056] Hereinafter, for convenience of explanation, a direction in which the cloth moves from the entry portion 60 of the gripping portion 50 to the body 10 located opposite the entry portion 60 of the gripping portion 50 is defined as a forward direction, and a direction in which the cloth moves to the entry portion 60 of the gripping portion 50 from the body 10 located opposite the entry portion 60 is defined as a reverse direction.
[0057] Referring to FIGS. 2 and 3, the other end of the reverse flow preventing piece 40 does not contact the support 20 and has a gap therebetween, the support 20 facing the support 20a to which the hanging pressure adjusting piece 30 is connected. When the hanger for preventing the reverse flow of the cloth with adjustable hanging pressure is formed of synthetic resin, the hanger 100 is manufactured by injecting raw materials into a mold. When the mold is manufactured and the other end of the reverse flow preventing piece 40 contacts the support 20 facing the support 20a connected to the hanging pressure adjusting piece 30, the other end of the reverse flow preventing piece 40 is connected and attached to the support 20 during the injection. Therefore, the other end of the reverse flow preventing piece 40 is formed not to contact the support 20 and has the gap therebetween.
[0058] That is, as shown in FIGS. 2 and 3, when the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70, the other end of the reverse flow preventing piece 40 does not contact the support 20 and has the gap therebetwen.
[0059] FIG. 4 is a partially enlarged view of a state in which the cloth 80 slips, according to the first embodiment. Referring to FIG. 4, thin cloth 80 is secured between the support 20 and the other end of the reverse flow preventing piece 40. Since the other end of the reverse flow preventing piece 40 is not in contact with the cloth 80, the cloth 80 slips downwards.
[0060] In other words, in a state in which the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70, since the other end of the reverse flow preventing piece 40 is not in contact with the support 20, the cloth 80, which is thinner than the gap between the other end of the reverse flow preventing piece 40 and the support 20, may not be secured to the reverse flow preventing piece 40 and thus may move in the reverse direction and fall.
[0061] FIG. 5 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to the first embodiment. FIG. 5 illustrates that the other end of the hanging pressure adjusting piece 30 is hung on a middle one among three hanging pressure adjusting piece projections 70 formed on the body 10. Since the other end of the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70, the hanging pressure adjusting piece 30 is slanted. Accordingly, the reverse flow preventing piece 40, which has the end connected to the hanging pressure adjusting piece 30 and the other end obliquely extending towards the body 10, is more slanted, and the other end of the reverse flow preventing piece 40 contacts the support 20 and is slightly bent.
[0062] FIG. 6 is a partially enlarged view illustrating a state in which the cloth 80 is being secured to the gripping portion 50 while the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to the first embodiment. As shown in FIG. 5, the other end of the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70, and although the reverse flow preventing piece 40 is more slanted and the other end of the reverse flow preventing piece 40 is in contact with the support 20, since the reverse flow preventing piece 40 has elasticity and the other end thereof is slanted upwards, when the cloth 80 is secured in the forward direction A upwards, the cloth 80 pushes the reverse flow preventing piece 40 upwards and produces a gap between the reverse flow preventing piece 40 and the support 20 and thus is secured in the forward direction A.
[0063] Here, at least one of the support 20 and the reverse flow preventing piece 40 has elasticity, and an action of securing the cloth 80 is smoothly performed.
[0064] FIG. 7 is a partially enlarged view illustrating a state in which the cloth 80 is secured to the reverse flow preventing piece 40 of the gripping portion 50 while the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to the first embodiment. As shown in FIG. 7, in a state in which the other end of the reverse flow preventing piece 40 contacts the support 20, when a user removes their hand from the cloth 80 after the cloth 80 is secured to the gripping portion 50 while contacting the other end of the reverse flow preventing piece 40 through the entry portion 60, the cloth 80 moves in the reverse direction B due to gravity and tends to slip through the entry portion 60. In this case, the reverse flow preventing piece 40 is unfolded due to elasticity, and the other end of the reverse flow preventing piece 40 touches and is secured to the cloth 80 in such a manner that the surface of the cloth 80 is bent.
[0065] Since the cloth 80 has a soft surface, a shape of the surface is changed by a shape of an object that contacts and presses the surface of the cloth 80. When a portion of the cloth 80 is sharply pressed, the portion is deeply pressed and folded. Since the end of the reverse flow preventing piece 40, to which the cloth 80 is secured, is more slanted towards the body 10 than a portion of the reverse flow preventing piece 40 that is connected to the support 20a, the cloth 80 is not able to move in the reverse direction B even though pressure is applied to the cloth 80 to make the cloth 80 move in the reverse direction B. The cloth 80 is not able to move in a downward direction, that is, the reverse direction B that is opposite to a direction in which the cloth 80 enters.
[0066] Therefore, while the other end of the reverse flow preventing piece 40 is in contact with the support 20, the cloth 80 secured between the reverse flow preventing piece 40 and the support 20 does not fall to the ground.
[0067] FIG. 8 is a partially enlarged view illustrating a state in which the cloth 80, which is secured to the reverse flow preventing piece 40 of the gripping portion 50, is obliquely removed upwards while the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to the first embodiment, which is viewed from the side. As shown in FIG. 8, in a state in which the other end of the reverse flow preventing piece 40 is in contact with the support 20, the cloth 80, which is secured between the reverse flow preventing piece 40 and the support 20, is obliquely lifted upwards by rotating a bottom portion of the cloth 80 in a direction C and obliquely drawn in a direction D. The reverse flow preventing piece 40 prevents the cloth 80 from moving in the reverse direction B, but does not prevent the movement of the cloth 80 in the forward direction A. Therefore, because the cloth 80 may smoothly move in the direction D that is almost the same as the forward direction A, the cloth 80 may be easily removed from the hanger for preventing the reverse flow of the cloth with the adjustable hanging pressure.
[0068] In the first embodiment of the hanger shown in FIGS. 2, 3, and 5, three hanging pressure adjusting piece projections 70 are formed on the body 10, and depending on where the hanging pressure adjusting piece 30 is hung, the intensity of pressure applied to the cloth 80 by the reverse flow preventing piece 40 due to elasticity of the reverse flow preventing piece 40 may differ. FIG. 5 shows that the hanging pressure adjusting piece 30 is hung on the middle one among three hanging pressure adjusting piece projections 70, but when the hanging pressure adjusting piece 30 is hung on the pressure adjusting piece projection 70 that is close to the support 20a connected to the end of the hanging pressure adjusting piece 30, a gradient of the hanging pressure adjusting piece 30 decreases and the intensity of the pressure that the reverse flow preventing piece 40 applies to the cloth 80 due to elasticity may relatively decrease. On the other hand, when the hanging pressure adjusting piece 30 is hung on the pressure adjusting piece projection 70 that is farthest from the support 20a connected to the end of the hanging pressure adjusting piece 30, the gradient of the hanging pressure adjusting piece 30 increases, and the intensity of the pressure that the reverse flow preventing piece 40 applies to the cloth 80 due to elasticity may relatively increase.
[0069] When the intensity of the pressure that the reverse flow preventing piece 40 applies to the cloth 80 due to elasticity decreases, it is easy and convenient to place the cloth 80 between the support 20 and the reverse flow preventing piece 40 through the entry portion 60 of the hanger, or remove the cloth 80 from between the support 20 and the reverse flow preventing piece 40. On the other hand, when wind blows or the hanger is shaken, the cloth may easily fall. When the intensity of the pressure that the reverse flow preventing piece 40 applies to the cloth 80 due to elasticity increases, it is difficult to place the cloth 80 between the support 20 and the reverse flow preventing piece 40 through the entry portion 60 of the hanger, or remove the cloth 80 from between the support 20 and the reverse flow preventing piece 40. However, when wind blows or the hanger is shaken, the cloth 80 may be firmly secured not to fall.
[0070] The user may hang the hanging pressure adjusting piece 30 on an appropriate one of the hanging pressure adjusting piece projections 70 depending on a thickness or weight of the cloth 80 and adjust the intensity of pressure that the reverse flow preventing piece 40 applies to the cloth 80 due to elasticity, and thus, the user may easily hang or remove the cloth 80 and allow the cloth 80 to be firmly secured.
[0071] The basic actions of securing/hanging/removing the cloth to/on/from the hanger which are described with reference to FIGS. 4, 6, 7, and 8 are applied to other embodiments below on the same principle.
[0072] FIG. 9 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to a second embodiment. As shown in FIG. 9, the hanging pressure adjusting piece projections 70 may be formed on the support 20a, not on the body 10. When the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 formed on the support 20a, the hanging pressure adjusting piece 30 having elasticity is bent and becomes convex in a middle portion thereof, and thus, the hanging pressure adjusting piece 30 comes close to the support 20 facing the support 20a connected to the hanging pressure adjusting piece 30. The reverse flow preventing piece 40 having one end connected to the hanging pressure adjusting piece 30 and the other end obliquely extending towards the body 10 is relatively and increasingly slanted, and the other end of the reverse flow preventing piece 40 contacts the support 20, thus being bent. As in the first embodiment, the cloth 80 may smoothly flow in the gripping portion 50 in the forward direction A and may be prevented from flowing in the reverse direction B, and thus, the functions of securing, hanging, and removing the cloth 80 may be easily performed.
[0073] FIG. 10 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to a third embodiment. As shown in FIG. 10, the hanging pressure adjusting piece projections 70 may be formed on both the body 10 and the support 20a. The other end of the reverse flow preventing piece 40, which has one end connected to the hanging pressure adjusting piece 30 and the other end obliquely extending towards the body 10, contacts the support 20 by hanging the hanging pressure adjusting piece 30 on the hanging pressure adjusting piece projection 70 formed on the body 10 or on the hanging pressure adjusting piece projection 70 formed on the support 20a, and thus, as in the first embodiment, the flow of the cloth 80 in the gripping portion 50 is smooth in the forward direction A and is prevented in the reverse direction B, and the functions of securing, hanging, and removing the cloth 80 may be easily performed.
[0074] The hanging pressure adjusting piece 30 may extend from one of the supports 20 and 20a, the reverse flow preventing piece 40 may extend from the other one of the supports 20 and 20a, and the reverse flow preventing piece 40 may elastically face the hanging pressure adjusting piece 30. The hanging pressure adjusting piece projections 70 may be formed on at least one of the body 10 and the support connected to the hanging pressure adjusting piece 30.
[0075] FIG. 11 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70 of the hanger, according to a fourth embodiment. Referring to FIG. 11, the ends of the supports 20 and 20a are respectively connected to both ends of the body 10, and the other ends of the supports 20 and 20a elongate such that the gripping portion 50 in which the cloth 80 is secured is formed. The end of the hanging pressure adjusting piece 30 is connected to the end of the support 20, which is one of the supports 20 and 20a forming the gripping portion 50, and the other end of the hanging pressure adjusting piece 30 extends towards the body 10. On the body 10, three hanging pressure adjusting piece projections 70 are formed, and the hanging pressure adjusting piece 30 is not hung on any of the hanging pressure adjusting piece projections 70.
[0076] The end of the reverse flow preventing piece 40 is connected to the end of the support 20a facing the support 20 connected to the hanging pressure adjusting piece 30, and the other end of the reverse flow preventing piece 40 obliquely extends towards the body 10.
[0077] In the first to third embodiments, the reverse flow preventing piece 40 is connected to the hanging pressure adjusting piece 30 connected to the support 20a, but in the fourth embodiment, the reverse flow preventing piece 40 is not connected to the hanging pressure adjusting piece 30, and the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40 are respectively connected to the supports 20 and 20a.
[0078] Since the hanging pressure adjusting piece 30 is not hung on any of the hanging pressure adjusting piece projections 70, the other end of the reverse flow preventing piece 40 does not contact the hanging pressure adjusting piece 30 with a gap therebetween. As in the first embodiment, when the thin cloth 80 is secured between the hanging pressure adjusting piece 30 and the other end of the reverse flow preventing piece 40, the other end of the reverse flow preventing piece 40 is not in contact with the cloth 80, and thus, the cloth 80 may slip downwards. That is, when the hanging pressure adjusting piece 30 is not hung on any of the hanging pressure adjusting piece projections 70, the other end of the reverse flow preventing piece 40 does not contact the hanging pressure adjusting piece 30, and the cloth 80, which is thinner than the gap between the other end of the reverse flow preventing piece 40 and the hanging pressure adjusting piece 30, may not be secured to the reverse flow preventing piece 40 and thus may move in the reverse direction, thereby falling.
[0079] FIG. 12 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projections 70 of the hanger of FIG. 11, according to the fourth embodiment. Referring to FIG. 12, the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40 are connected to the supports 20 and 20a, respectively. The other end of the hanging pressure adjusting piece 30 connected to the support 20, which is one of the supports 20 and 20a, is hung on a middle one among three hanging pressure adjusting piece projections 70 formed on the body 10.
[0080] The end of the hanging pressure adjusting piece 30 is connected to the support 20 that is not connected to the reverse flow preventing piece 40, and the other end of the hanging pressure adjusting piece 30 is slanted towards the support 20a connected to the reverse flow preventing piece 40 and faces the body 10.
[0081] Since the other end of the reverse flow preventing piece 40 connected to the support 20a is placed in a middle portion of the gripping portion 50, the other end of the reverse flow preventing piece 40 contacts the hanging pressure adjusting piece 30, which is slanted, and applies pressure to the hanging pressure adjusting piece 30, thereby being bent.
[0082] Here, the cloth 80 is secured between the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40. As in the first or second embodiment, since the reverse flow preventing piece 40 has elasticity and the other end thereof is slanted upwards, when the cloth 80 is secured in an upward direction, the cloth 80 may push the reverse flow preventing piece 40 upwards and produce a gap with the hanging pressure adjusting piece 30 such that the cloth 80 moves in the forward direction A and is secured.
[0083] When the cloth 80 secured in the upward direction stops moving, the reverse flow preventing piece 40 presses the cloth 80 due to elasticity and is secured to the cloth 80, and thus, the cloth 80 may not move in a downward direction, that is, the reverse direction that is opposite to the direction in which the cloth 80 enters. Therefore, the cloth 80 secured between the other end of the reverse flow preventing piece 40 and the hanging pressure adjusting piece 30 does not fall.
[0084] Also, since the reverse flow preventing piece 40 prevents the cloth 80 from moving in the reverse direction B but does not prevent the movement in the forward direction A, the cloth 80 is easily removed when the cloth 80 secured between the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40 is removed in the upward direction.
[0085] FIG. 13 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger, according to a fifth embodiment. Referring to FIG. 13, the hanging pressure adjusting piece projections 70 are formed on both the body 10 and the support 20. When the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 formed on the support 20, the hanging pressure adjusting piece 30 having elasticity is bent, becomes convex in a middle portion thereof, and comes close to the support 20a connected to the reverse flow preventing piece 40. Accordingly, the hanging pressure adjusting piece 30 contacts the reverse flow preventing piece 40, and the reverse flow preventing piece 40 is slightly bent because of the pressure applied to the other end thereof. The user hangs the hanging pressure adjusting piece 30 to the hanging pressure adjusting piece projection 70 formed on the body 10 or the hanging pressure adjusting piece projection 70 formed on the support 20 to apply pressure between the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40, and the cloth 80 smoothly flows in the gripping portion 50 in the forward direction A and is not allowed to flow in the reverse direction B. Thus, the functions of securing, hanging, and removing the cloth 80 may be easily performed.
[0086] The hanging pressure adjusting piece 30 may include a pair of hanging pressure adjusting pieces respectively extending from the supports 20 and 20a, the reverse flow preventing piece 40 may extend from one of the pair of hanging pressure adjusting pieces and face the other one thereof, and the hanging pressure adjusting piece projections 70 may be formed on the body 10.
[0087] FIG. 14 is a front view illustrating a state in which the hanging pressure adjusting pieces 30 are hung on the hanging pressure adjusting piece projection 70 of the hanger, according to a sixth embodiment. Referring to FIG. 14, the hanging pressure adjusting pieces 30 are connected to the support 20a and the support 20, and the reverse flow preventing piece 40 is connected to the hanging pressure adjusting piece 30 connected to the support 20a. Since the hanging pressure adjusting pieces 30 are hung on the hanging pressure adjusting piece projections 70 formed on the body 10, pressure is applied between the other end of the reverse flow preventing piece 40, which is connected to the hanging pressure adjusting piece 30 connected to the support 20a, and the hanging pressure adjusting piece 30 connected to the support 20.
[0088] Even in this case, depending on where the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 formed on the body 10, the intensity of the pressure that the reverse flow preventing piece 40 applies to the cloth 80 due to the intensity may differ. The reverse flow preventing piece 40 prevents the cloth 80 from moving in the reverse direction B, but does not prevent the cloth 80 from moving in the forward direction A, and thus, the user may easily perform the functions of securing/hanging/removing the cloth 80 to/on/from the reverse flow preventing piece 40, which is connected to the hanging pressure adjusting piece 30 connected to the support 20a, and the hanging pressure adjusting piece 30 connected to the support 20.
[0089] The hanging pressure adjusting piece 30 may include a pair of hanging pressure adjusting pieces respectively extending from the supports 20 and 20a, the reverse flow preventing piece 40 may include a pair of reverse flow preventing pieces respectively extending from the pair of hanging pressure adjusting pieces and elastically facing each other, and the hanging pressure adjusting piece projections 70 may be formed on the body 10.
[0090] FIG. 15 is a front view illustrating a state in which the hanging pressure adjusting pieces 30 are not hung on the hanging pressure adjusting piece projections 70 of the hanger, according to a seventh embodiment. Referring to FIG. 15, the hanging pressure adjusting pieces 30 are connected to the support 20a and the support 20, and the reverse flow preventing pieces 40 are respectively connected to the hanging pressure adjusting pieces 30. The cloth 80 is secured to the other ends of the reverse flow preventing pieces 40, but since the hanging pressure adjusting pieces 30 are not hung on the hanging pressure adjusting piece projections 70 formed on the body 10, the other ends of the reverse flow preventing pieces 40 do not contact each other, and thus, the thin cloth 80 may not be secured and may fall in the reverse direction.
[0091] When the user hangs the hanging pressure adjusting pieces 30 respectively on the hanging pressure adjusting piece projections 70 formed on the body 10 or one of the hanging pressure adjusting pieces 30 on one of the hanging pressure adjusting piece projections 70 formed on the body 10, the other ends of the reverse flow preventing pieces 40 contact each other, and thus the user may easily perform the functions of securing/hanging/removing the cloth 80 to/on/from the reverse flow preventing pieces 40.
[0092] The hanging pressure adjusting pieces 30 may extend from the body 10, and the hanging pressure adjusting piece projections 70 may be formed on one of the supports 20 and 20a which is close to the hanging pressure adjusting pieces 30. The reverse flow preventing pieces 40 may extend from the hanging pressure adjusting pieces 30 and may elastically face one of the supports 20 and 20a. The reverse flow preventing piece 40 may extend from one of the supports 20 and 20a and may elastically face the hanging pressure adjusting pieces 30.
[0093] FIG. 16 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70 of the hanger, according to an eighth embodiment. FIG. 17 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger of FIG. 16, according to the eighth embodiment. Referring to FIGS. 16 and 17, the hanging pressure adjusting piece 30 is not formed on the supports 20 and 20a but on the body 10.
[0094] The end of the hanging pressure adjusting piece 30 is connected to the body 10, and the other end of the hanging pressure adjusting piece 30 elongates downwards, and thus, the end of the reverse flow preventing piece 40 is connected to the other end of the hanging pressure adjusting piece 30. On the other end of the support 20a that is close to the hanging pressure adjusting piece 30, the hanging pressure adjusting piece projection 70 is formed. Referring to FIG. 16, in the state in which the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70, the other end of the reverse flow preventing piece 40 does not contact the support 20 and thus, the thin cloth 80 may not be secured to the other end of the reverse flow preventing piece 40 and may fall in the reverse direction B. Referring to FIG. 17, when the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 formed on the support 20a, the hanging pressure adjusting piece 30 is bent and convex in the middle portion thereof, and thus, the reverse flow preventing piece 40 connected to the end of the hanging pressure adjusting piece 30 is slanted more. Therefore, the other end of the reverse flow preventing piece 40 contacts the support 20 and is slightly bent due to the pressure applied thereto. When the user hangs the hanging pressure adjusting piece 30 formed on the body 10 on the hanging pressure adjusting piece projection 70 formed on the support 20a so as to apply pressure between the support 20 and the reverse flow preventing piece 40, the cloth 80 may easily flow in the gripping portion 50 in the forward direction A and is not allowed to move in the reverse direction B such that the user may easily perform the function of securing, hanging, and removing the cloth 80.
[0095] FIG. 18 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70 of the hanger, according to a ninth embodiment. FIG. 19 is a front view illustrating a state in which the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 of the hanger of FIG. 18, according to a ninth embodiment. The illustrations of FIGS. 18 and 19 are the same as those of FIGS. 16 and 17 in that the hanging pressure adjusting piece 30 is not connected to the supports 20 and 20a, but is connected to the body 10. However, the illustrations of FIGS. 18 and 19 are different from those of FIGS. 16 and 17 in that the end of the reverse flow preventing piece 40 is connected to the other end of the support 20a that is far from the hanging pressure adjusting piece 30, and the hanging pressure adjusting piece projection 70 is formed on the other end of the support 20 that is close to the hanging pressure adjusting piece 30. Referring to FIG. 18, in the state in which the hanging pressure adjusting piece 30 is not hung on the hanging pressure adjusting piece projection 70, the other end of the reverse flow preventing piece 40 does not contact the hanging pressure adjusting piece 30, and thus, when the thin cloth 80 is secured between the reverse flow preventing piece 40 and the hanging pressure adjusting piece 30, the cloth 80 may not be hung and may fall in the reverse direction. Referring to FIG. 19, when the hanging pressure adjusting piece 30 is hung on the hanging pressure adjusting piece projection 70 formed on the support 20, the hanging pressure adjusting piece 30 is bent and convex in the middle portion thereof, and the other end of the reverse flow preventing piece 40, which has one end connected to the other end of the support 20a, contacts the hanging pressure adjusting piece 30 and is slightly bent due to the pressure applied thereto. When the user hangs the hanging pressure adjusting piece 30 formed on the body 10 on the hanging pressure adjusting piece projection 70 formed on the support 20 so as to apply pressure between the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40, the cloth 80 is secured between the hanging pressure adjusting piece 30 and the reverse flow preventing piece 40 in the gripping portion 50, and the flow of the cloth 80 in the forward direction A is smooth and in the reverse direction B is prevented. Therefore, the user may easily perform the functions of securing, hanging, and removing the cloth 80.
[0096] FIG. 20 is a perspective view of a hanging device for preventing the reverse flow that is formed by horizontally connecting the hangers 100 for preventing the reverse flow of cloth with adjustable hanging pressure. As shown in FIG. 20, the hangers 100 are arranged in a lateral direction. The hangers 100 may be arranged in an extension direction of the body 10. Here, supports of the hangers 100 may be used as supports of adjacent hangers. The hanging device 200 may be used to easily and quickly secure and remove pieces of cloth and may be manufactured without a separate assembly by performing injection once with one mold. Therefore, the hanging device 200 may be easily manufactured, and manufacturing costs thereof may be reduced.
