- an air injection device 100 is a device that injects or discharges air into or from an air tube 300 located on at least a given area of a clothing body 200.
- the air injection device 100 communicates with the air tube 300 located on the clothing body 200 through a hose H, and the air tube 300 is expanded or contracted according to the air injected or discharged by means of the air injection device 100.
- the air injection device 100 includes a body 110, an opening and closing part 120, and a connecting part 130.
- the body 110 is open on both ends thereof and has an air passage 112 formed therein. Both ends of the body 110 are connected to the opening and closing part 120 and the connecting part 130, and the air passage 112 is open and closed according to a user's control for the opening and closing part 120.
- the body 110 has a guide groove 114 concavedly formed on an outer peripheral surface of one end thereof so as to allow the opening and closing part 120 to be coupled thereto and to guide the user's control for the opening and closing part 120, and also, the opening and closing part 120 has a guide protrusion 124 protruding from the inner peripheral surface thereof in such a manner as to be inserted into the guide groove 114.
- the guide groove 114 includes a first guide groove 114a and a second guide groove 114b and a third guide groove 114c that are extended from the first guide groove 114a.
- the first guide groove 114a is formed on the outer peripheral surface of one end of the body 110 in a longitudinal direction of the body 110
- the second guide groove 114b and the third guide groove 114c are extended from one end and the other end of the first guide groove 114a in a circumferential direction of the body 110.
- the first guide groove 114a serves to guide the longitudinal movement of the opening and closing part 120
- the second guide groove 114b and the third guide groove 114c serve to guide the rotation of the opening and closing part 120, so that they can guide the user's control for the opening and closing part 120.
- the guide protrusion 124 is moved along the first guide groove 114a by means of the user's first control, so that the opening and closing part 120 can be moved in a longitudinal direction (in a first direction toward the body 110 or in a second direction opposite to the first direction).
- the air passage 112 can be closed or open according to the movement of the opening and closing part 120 in the first direction or the second direction.
- the guide protrusion 124 is moved along the second guide groove 114b or the third guide groove 114c by means of the user's second control, so that the opening and closing part 120 can be rotated.
- the movement of the opening and closing part 120 in the longitudinal direction is limited or allowed according to the rotation (that is, rotating directions) of the opening and closing part 120.
- the air passage 112 can be kept in a closed or open state.
- the first control means the control for the movement of the opening and closing part 120 in the longitudinal direction
- the second control means the control for the rotation of the opening and closing part 120.
- At least one locking protrusion (whose reference numeral is not shown) is formed on at least one region of the second guide groove 114b and the third guide groove 114c to limit the rotation of the opening and closing part 120. While the opening and closing part 120 is being rotated, for example, the guide protrusion 124 moving along the second guide groove 114b or the third guide groove 114c is locked onto the locking protrusion formed on the given region of the second guide groove 114b or the third guide groove 114c, and accordingly, the rotation of the opening and closing part 120 is limited. If a given rotating force is applied to the opening and closing part 120, however, the guide protrusion 124 is moved over the locking protrusion.
- the opening and closing part 120 While the opening and closing part 120 is being rotated, accordingly, if the guide protrusion 124 reaches a given position, a given level of resistance is transferred to the user, and through the resistance, the user can recognize the positions and rotating degrees of the opening and closing part 120 and/or the guide protrusion 124.
- a fourth guide groove (whose reference numeral is not shown) is extended from one side of the third guide groove 114c so as to separate the body 110 from the opening and closing part 120.
- the fourth guide groove is extended from one end portion of the third guide groove 114c in the longitudinal direction (the second direction) of the body 110, so that the guide protrusion 124 can be moved along the fourth guide groove through the user's control to allow the opening and closing part 120 to be separated from the body 110.
- a limitation projection (whose reference numeral is not shown) is formed on one side of the fourth guide groove to limit the escape of the opening and closing part 120, thereby preventing the body 110 from being arbitrarily separated from the opening and closing part 120.
- the fourth guide groove is extended from the third guide groove 114c, but it is greater in height than the third guide groove 114c in the circumferential direction of the body 110, so that the limitation projection is formed on a portion where the fourth guide groove is connected to the third guide groove 114c.
- the guide protrusion 124 is located on one end portion of the third guide groove 114c, accordingly, the guide protrusion 124 comes into contact with the limitation projection, so that it is not immediately moved to the fourth guide groove, thereby limiting the separation of the opening and closing part 120 from the body 110. If a given external force is applied to the opening and closing part 120, however, the guide protrusion 124 escapes from the limitation projection and moves along the fourth guide groove, thereby allowing the opening and closing part 120 to be separated from the body 110.
- the body 110 So as to allow the body 110 to be coupled to the connecting part 130, further, the body 110 has a first screw thread 116 formed along the inner peripheral surface of the other end thereof.
- the opening and closing part 120 is coupled to one end portion of the body 110 and is moved in a longitudinal direction of the air injection device 100 by means of the use's control, thereby opening and closing the air passage 112 of the body 110.
- the opening and closing part 120 has an opening and closing protrusion 122 protruding from the inner surface of one end thereof toward the body 110.
- the opening and closing part 120 and the opening and closing protrusion 122 are moved in the first direction toward the body 110 or in the second direction opposite to the first direction by means of the user's control, in detail, the opening and closing protrusion 122 is inserted into the air passage 112 or drawn from the air passage 112, thereby closing or opening the air passage 112 of the body 110.
- the opening and closing protrusion 122 has a size corresponding to an inner diameter of the air passage 112 so as to tightly close the air passage 112.
- the opening and closing part 120 has at least one air injection hole 126 penetratingly formed therein around the opening and closing protrusion 122. If the opening and closing protrusion 122 is drawn from the air passage 112, the air passage 112 can communicate with the outside through the air injection hole 126, so that through the air injection hole 126, air is injected into the air tube 300 or air remaining in the air tube 300 is discharged to the outside.
- the connecting part 130 is coupled to the other end of the body 110 in such a manner as to communicate with the body 110 and the opening and closing part 120. Further, the connecting part 130 is connected to one end periphery of the hose H to allow the air injection device 100 to communicate with the air tube 300. To do this, the connecting part 130 includes a coupling member 132 and a fixing member 134.
- the coupling member 132 is formed to penetrate an interior thereof, and at least a portion of the coupling member 132 is inserted into the hose H, so that an interior of the connecting part 130 can communicate with the hose H.
- the fixing member 134 is spaced apart from an outer peripheral surface of the coupling member 132 by a given distance in such a manner as to surround the outer peripheral surface of the coupling member 132, while pressurizing an outer peripheral surface of the hose H coupled to the coupling member 132 to prevent the hose H from escaping from the coupling member 132.
- the fixing member 134 has a second screw thread 136 formed on an outer peripheral surface thereof in such a manner as to correspond to the first screw thread 116, thereby allowing the connecting part 130 to be screw-coupled to the body 110.
- one end periphery of the hose H is located at a gap between the coupling member 132 and the fixing member 134, and as the body 110 is screw-coupled to the outer peripheral surface of the fixing member 134, the outer peripheral surface of one end portion of the hose H is pressurized in a direction vertical with respect to a center axis of the air injection device 100, thereby preventing the hose H from being arbitrarily separated from the coupling member 132.
- the air injection device 100 as shown in FIGS.1 to 3 is just exemplary, and accordingly, it can be configured freely according to embodiments of the present invention.
- the connecting part 120 and the body 110 are formed integrally with each other, and otherwise, at least one of the body 110, the opening and closing part 120, and the connecting part 130 is changed in position.
- FIGS.4a and 4b are sectional views showing operating states of the air injection device according to the first embodiment of the present invention.
- FIG.4a shows a state where the air passage 112 of the air injection device 100 is closed
- FIG.4b shows a state where the air passage 112 of the air injection device 100 is open.
- the opening and closing part 120 is moved in the first direction toward the body 110 by means of the user's control to allow the opening and closing protrusion 122 to be inserted into the air passage 112, and as the opening and closing part 120 is rotated in one direction, in this case, the guide protrusion 124 is located on the second guide groove 114b to allow the opening and closing protrusion 122 to be kept in a state of being inserted into the air passage 112. If the air injection device 100 is not used, accordingly, the air passage 112 is closed to prevent air from being discharged from the air tube 300.
- the opening and closing part 120 is rotated in the other direction opposite to one direction, and accordingly, the guide protrusion 124 is located on the first guide groove 114a, thereby allowing the opening and closing part 120 to be moved in the longitudinal direction.
- the opening and closing part 120 is controlled by the user to open the air passage 112 of the air injection device 100, and accordingly, the opening and closing part 120 is moved in the second direction opposite to the first direction to allow the opening and closing protrusion 122 from being drawn from the air passage 112.
- the guide protrusion 124 is located on the third guide groove 114c to allow the opening and closing protrusion 122 to be kept in a state of being drawn from the air passage 112. Accordingly, the hose H communicates with the air injection hole 126 to allow external air to injected or discharged into or from the air tube 300.
- FIGS.5a to 5c are perspective views showing operating methods of the air injection device according to the first embodiment of the present invention.
- the guide protrusion 124 is located on the second guide groove 114b to prevent the opening and closing part 120 from being moved in the longitudinal direction thereof, so that the opening and closing protrusion 122 is kept in the state of being inserted into the air passage 112.
- the opening and closing part 120 is rotated in one direction (for example, clockwise direction), and accordingly, the guide protrusion 124 is moved along the second guide groove 114b, then escapes from the second guide groove 114b, and is finally located on one end of the first guide groove 114a.
- the opening and closing part 120 can be moved in the longitudinal direction thereof by means of the user's control. As shown in FIG.5b , if the opening and closing part 120 is moved in the second direction (that is, the direction opposite to the first direction), the guide protrusion 124 is moved along the first guide groove 114a, and accordingly, the guide protrusion 124 is drawn from the air passage 124, thereby opening the air passage 112.
- the guide protrusion 124 is moved along the first guide groove 114a and is then located at the other end portion of the first guide groove 114a. If the guide protrusion 124 is located on the other end portion of the first guide groove 114a, the movement of the opening and closing part 120 in the second direction is limited, and in this case, if the opening and closing part 120 is rotated in the other direction (for example, counterclockwise direction) opposite to one direction by means of the user's control, the guide protrusion 124 is moved along the third guide groove 114c. Accordingly, the guide protrusion 124 is located on the third guide groove 114c to prevent the opening and closing part 120 from being moved in the longitudinal direction thereof, thereby allowing the air passage 112 to be kept in an open state.
- the operations of the air injection device 100 are just exemplary, and of course, they can be changed freely according to embodiments of the present invention through one having ordinary skills in the art.

body 110 has aguide groove 114 concavedly formed on an outer peripheral surface of one end thereof so as to allow the opening and closingpart 120 to be coupled thereto and to guide the user's control for the opening and closingpart 120, and also, the opening and closingpart 120 has aguide protrusion 124 protruding from the inner peripheral surface thereof in such a manner as to be inserted into theguide groove 114. - The
guide groove 114 includes afirst guide groove 114a and asecond guide groove 114b and athird guide groove 114c that are extended from thefirst guide groove 114a. For example, thefirst guide groove 114a is formed on the outer peripheral surface of one end of thebody 110 in a longitudinal direction of thebody 110, and thesecond guide groove 114b and thethird guide groove 114c are extended from one end and the other end of thefirst guide groove 114a in a circumferential direction of thebody 110. - Accordingly, the
first guide groove 114a serves to guide the longitudinal movement of the opening and closingpart 120, and thesecond guide groove 114b and thethird guide groove 114c serve to guide the rotation of the opening and closingpart 120, so that they can guide the user's control for the opening and closingpart 120. - In a state where the opening and closing
part 120 is coupled to thebody 110, in detail, theguide protrusion 124 is moved along thefirst guide groove 114a by means of the user's first control, so that the opening and closingpart 120 can be moved in a longitudinal direction (in a first direction toward thebody 110 or in a second direction opposite to the first direction). As a result, theair passage 112 can be closed or open according to the movement of the opening and closingpart 120 in the first direction or the second direction. - Further, the
guide protrusion 124 is moved along thesecond guide groove 114b or thethird guide groove 114c by means of the user's second control, so that the opening and closingpart 120 can be rotated. The movement of the opening and closingpart 120 in the longitudinal direction is limited or allowed according to the rotation (that is, rotating directions) of the opening and closingpart 120. As the movement of the opening and closingpart 120 in the longitudinal direction is limited, particularly, theair passage 112 can be kept in a closed or open state. - In this case, the first control means the control for the movement of the opening and closing
part 120 in the longitudinal direction, and the second control means the control for the rotation of the opening and closingpart 120. An explanation on a method for controlling the opening and closingpart 120 with respect to thebody 110 will be in detail given later with reference toFIGS.5a to 5c . - According to the present invention, at least one locking protrusion (whose reference numeral is not shown) is formed on at least one region of the
second guide groove 114b and thethird guide groove 114c to limit the rotation of the opening and closingpart 120. While the opening and closingpart 120 is being rotated, for example, theguide protrusion 124 moving along thesecond guide groove 114b or thethird guide groove 114c is locked onto the locking protrusion formed on the given region of thesecond guide groove 114b or thethird guide groove 114c, and accordingly, the rotation of the opening and closingpart 120 is limited. If a given rotating force is applied to the opening and closingpart 120, however, theguide protrusion 124 is moved over the locking protrusion. - While the opening and closing
part 120 is being rotated, accordingly, if theguide protrusion 124 reaches a given position, a given level of resistance is transferred to the user, and through the resistance, the user can recognize the positions and rotating degrees of the opening and closingpart 120 and/or theguide protrusion 124. - According to the present invention, further, a fourth guide groove (whose reference numeral is not shown) is extended from one side of the
third guide groove 114c so as to separate thebody 110 from the opening and closingpart 120. For example, the fourth guide groove is extended from one end portion of thethird guide groove 114c in the longitudinal direction (the second direction) of thebody 110, so that theguide protrusion 124 can be moved along the fourth guide groove through the user's control to allow the opening and closingpart 120 to be separated from thebody 110. - In this case, a limitation projection (whose reference numeral is not shown) is formed on one side of the fourth guide groove to limit the escape of the opening and closing
part 120, thereby preventing thebody 110 from being arbitrarily separated from the opening and closingpart 120. For example, the fourth guide groove is extended from thethird guide groove 114c, but it is greater in height than thethird guide groove 114c in the circumferential direction of thebody 110, so that the limitation projection is formed on a portion where the fourth guide groove is connected to thethird guide groove 114c. - If the
guide protrusion 124 is located on one end portion of thethird guide groove 114c, accordingly, theguide protrusion 124 comes into contact with the limitation projection, so that it is not immediately moved to the fourth guide groove, thereby limiting the separation of the opening and closingpart 120 from thebody 110. If a given external force is applied to the opening and closingpart 120, however, theguide protrusion 124 escapes from the limitation projection and moves along the fourth guide groove, thereby allowing the opening and closingpart 120 to be separated from thebody 110. - So as to allow the
body 110 to be coupled to the connectingpart 130, further, thebody 110 has afirst screw thread 116 formed along the inner peripheral surface of the other end thereof. - The opening and closing
part 120 is coupled to one end portion of thebody 110 and is moved in a longitudinal direction of theair injection device 100 by means of the use's control, thereby opening and closing theair passage 112 of thebody 110. To do this, the opening and closingpart 120 has an opening and closingprotrusion 122 protruding from the inner surface of one end thereof toward thebody 110. - As the opening and closing
part 120 and the opening and closingprotrusion 122 are moved in the first direction toward thebody 110 or in the second direction opposite to the first direction by means of the user's control, in detail, the opening and closingprotrusion 122 is inserted into theair passage 112 or drawn from theair passage 112, thereby closing or opening theair passage 112 of thebody 110. The opening and closingprotrusion 122 has a size corresponding to an inner diameter of theair passage 112 so as to tightly close theair passage 112. - According to the present invention, the opening and closing
part 120 has at least oneair injection hole 126 penetratingly formed therein around the opening and closingprotrusion 122. If the opening and closingprotrusion 122 is drawn from theair passage 112, theair passage 112 can communicate with the outside through theair injection hole 126, so that through theair injection hole 126, air is injected into theair tube 300 or air remaining in theair tube 300 is discharged to the outside. - The connecting
part 130 is coupled to the other end of thebody 110 in such a manner as to communicate with thebody 110 and the opening and closingpart 120. Further, the connectingpart 130 is connected to one end periphery of the hose H to allow theair injection device 100 to communicate with theair tube 300. To do this, the connectingpart 130 includes acoupling member 132 and a fixingmember 134. - The
coupling member 132 is formed to penetrate an interior thereof, and at least a portion of thecoupling member 132 is inserted into the hose H, so that an interior of the connectingpart 130 can communicate with the hose H. - The fixing
member 134 is spaced apart from an outer peripheral surface of thecoupling member 132 by a given distance in such a manner as to surround the outer peripheral surface of thecoupling member 132, while pressurizing an outer peripheral surface of the hose H coupled to thecoupling member 132 to prevent the hose H from escaping from thecoupling member 132. The fixingmember 134 has asecond screw thread 136 formed on an outer peripheral surface thereof in such a manner as to correspond to thefirst screw thread 116, thereby allowing the connectingpart 130 to be screw-coupled to thebody 110. - If the
coupling member 132 is inserted into the hose H, accordingly, one end periphery of the hose H is located at a gap between thecoupling member 132 and the fixingmember 134, and as thebody 110 is screw-coupled to the outer peripheral surface of the fixingmember 134, the outer peripheral surface of one end portion of the hose H is pressurized in a direction vertical with respect to a center axis of theair injection device 100, thereby preventing the hose H from being arbitrarily separated from thecoupling member 132. - The
air injection device 100 as shown inFIGS.1 to 3 is just exemplary, and accordingly, it can be configured freely according to embodiments of the present invention. For example, the connectingpart 120 and thebody 110 are formed integrally with each other, and otherwise, at least one of thebody 110, the opening and closingpart 120, and the connectingpart 130 is changed in position. -
FIGS.4a and 4b are sectional views showing operating states of the air injection device according to the first embodiment of the present invention. -
FIG.4a shows a state where theair passage 112 of theair injection device 100 is closed, andFIG.4b shows a state where theair passage 112 of theair injection device 100 is open. - As shown in
FIG.4a , first, the opening and closingpart 120 is moved in the first direction toward thebody 110 by means of the user's control to allow the opening and closingprotrusion 122 to be inserted into theair passage 112, and as the opening and closingpart 120 is rotated in one direction, in this case, theguide protrusion 124 is located on thesecond guide groove 114b to allow the opening and closingprotrusion 122 to be kept in a state of being inserted into theair passage 112. If theair injection device 100 is not used, accordingly, theair passage 112 is closed to prevent air from being discharged from theair tube 300. - As shown in
FIG.4b , in the state where theair passage 112 is closed, the opening and closingpart 120 is rotated in the other direction opposite to one direction, and accordingly, theguide protrusion 124 is located on thefirst guide groove 114a, thereby allowing the opening and closingpart 120 to be moved in the longitudinal direction. Next, the opening and closingpart 120 is controlled by the user to open theair passage 112 of theair injection device 100, and accordingly, the opening and closingpart 120 is moved in the second direction opposite to the first direction to allow the opening and closingprotrusion 122 from being drawn from theair passage 112. As the opening and closingpart 120 is rotated in one direction, in this case, theguide protrusion 124 is located on thethird guide groove 114c to allow the opening and closingprotrusion 122 to be kept in a state of being drawn from theair passage 112. Accordingly, the hose H communicates with theair injection hole 126 to allow external air to injected or discharged into or from theair tube 300. -
FIGS.5a to 5c are perspective views showing operating methods of the air injection device according to the first embodiment of the present invention. - Referring first to
FIG.5a , in the state where the opening and closingpart 120 is moved in the first direction (that is, toward the body 110) to allow theair passage 112 to be closed, theguide protrusion 124 is located on thesecond guide groove 114b to prevent the opening and closingpart 120 from being moved in the longitudinal direction thereof, so that the opening and closingprotrusion 122 is kept in the state of being inserted into theair passage 112. After that, if it is desired to open theair passage 112, the opening and closingpart 120 is rotated in one direction (for example, clockwise direction), and accordingly, theguide protrusion 124 is moved along thesecond guide groove 114b, then escapes from thesecond guide groove 114b, and is finally located on one end of thefirst guide groove 114a. - Referring next to
FIG.5b , if theguide protrusion 124 is located on thefirst guide groove 114a, the opening and closingpart 120 can be moved in the longitudinal direction thereof by means of the user's control. As shown inFIG.5b , if the opening and closingpart 120 is moved in the second direction (that is, the direction opposite to the first direction), theguide protrusion 124 is moved along thefirst guide groove 114a, and accordingly, theguide protrusion 124 is drawn from theair passage 124, thereby opening theair passage 112. - Referring to
FIG.5c , if the opening and closingpart 120 is continuously moved in the second direction by means of the user's control, theguide protrusion 124 is moved along thefirst guide groove 114a and is then located at the other end portion of thefirst guide groove 114a. If theguide protrusion 124 is located on the other end portion of thefirst guide groove 114a, the movement of the opening and closingpart 120 in the second direction is limited, and in this case, if the opening and closingpart 120 is rotated in the other direction (for example, counterclockwise direction) opposite to one direction by means of the user's control, theguide protrusion 124 is moved along thethird guide groove 114c. Accordingly, theguide protrusion 124 is located on thethird guide groove 114c to prevent the opening and closingpart 120 from being moved in the longitudinal direction thereof, thereby allowing theair passage 112 to be kept in an open state. - The operations of the
air injection device 100 are just exemplary, and of course, they can be changed freely according to embodiments of the present invention through one having ordinary skills in the art. -
FIGS.6a and6b show functional clothing according to the present invention. - In detail,
FIG.6a showsfunctional clothing 500 in which air is discharged from theair tube 300, andFIG.6b shows thefunctional clothing 500 in which air is introduced into theair tube 300. - Referring to
FIGS.6a and6b , thefunctional clothing 500 includes theair injection device 100, theclothing body 200, theair tube 300, and the hose H. - The
clothing body 200 has a shape of upper or lower clothing capable of being worn on the user, and of course, it may include all types of clothing or accessories capable of worn on the user, without being limited thereto. - The
air tube 300 is located on one side of theclothing body 200. Theair injection device 100 is detachably coupled to theair tube 300 to introduce or discharge air into or from theair tube 300. Accordingly, theair tube 300 introduces or discharges the air through theair injection device 100 and provides a feeling like a cushion to one area of theclothing body 200. - According to the present invention, as shown in
FIGS.6a and6b , theair tube 300 is located on an area corresponding to the user's neck, but it may be located on joint portions such as wrists, knees, and so on or various areas required to absorb external impacts or to support the user's posture. As theair tube 300 is expanded with the air introduced through theair injection device 100, accordingly, theair tube 300 applies an expansion force to one area of thefunctional clothing 500, like a cushion, to protect the user from fatigues or injuries caused by his or her activities. Further, the air is discharged from theair tube 300 if necessary, thereby improving the user's wearing comfort or activities. - So as to perform the air communication with the
air tube 300, theair injection device 100 and theair tube 300 are connected to each other by means of the hose H. In detail, one end periphery of the hose H is connected to the connectingpart 130 of theair injection device 100, and the other end periphery of the hose H is connected to theair tube 300, so that theair injection device 100 can communicate with theair tube 300. Through the control of the opening and closingpart 120, theair passage 112 of theair injection device 100 is open or closed. If theair passage 112 is open, air blows by the user from theair injection hole 126 of the opening and closingpart 120 into theair tube 300 through theair passage 112, and otherwise, air is discharged from theair tube 300 to the opening and closingpart 120. If theair passage 112 is closed, contrarily, theair tube 300 can be kept in the state where the air is introduced or discharged thereinto or therefrom. - According to the present invention, further, the hose H is connected to a
connector 400 coupled to theair tube 300. This will be in detail explained later with reference toFIG.7 . - According to the present invention, as at least a portion of the
clothing body 200 is coated, theair tube 300 is formed integrally with theclothing body 200. For example, polyurethane coating (PU coating) is performed by applying a polyurethane material to at least a portion of an inner surface of theclothing body 200, by performing thermal fusion on edges of the coated area, and by sealing the portion of the inner surface of theclothing body 200. However, the coating is not limited to the polyurethane coating, and it may be performed with a variety of materials. For example, the coating may be performed with a polyethylene material or a combination of polyurethane and polyethylene. - In detail, the
functional clothing 500 according to the present invention is configured to allow theair tube 300 to be formed integrally with theclothing body 200 in such a manner as to be coated on the given area of theclothing body 200 to seal the portion surrounding the coated area and to thus form a space inside theclothing body 200, into which air is introduced. Especially, coating is performed onto theclothing body 200 itself so as to prevent air from permeating through a fabric constituting theclothing body 200, and accordingly, the air in theair tube 300 is prevented from being discharged to the outside. As a result, thefunctional clothing 500, which is formed integrally with theair tube 300, can be manufactured more efficiently, irrespective of a material of theclothing body 200. - According to the present invention, further, the
air tube 300 is detachably mounted inside or outside theclothing body 200. - A physical property measurement test was carried out for two same fabrics, that is, one fabric onto which polyurethane is coated according to the present invention and the other fabric onto which no coating is performed according to a comparison example. The physical property measurement test was largely divided into mechanical tests and functionality tests.
- For the mechanical tests, first, a tensile strength test (KS K 0642,8.14.1, grab method) was carried out to check a resistance to a force of pulling a fabric, a tearing strength test (KS K 0642,8,17.4, pendulum method) to check a force necessary to tear a fabric, a bursting strength test (KS K ISO 13938-1, oil pressure method) to check a strength until a fabric bursts with a pressure applied vertically thereto, a peel strength test (KS K 0533) to check a resistance to peel of a fabric, an elastic recovery test (KS K 0541) to check a degree of recovery for a fabric extended by an external force, and an air permeability test (KS K ISO 9237) to check a degree of air permeability into spaces (pores) of a fabric.
- For the functionality tests, next, a hydrostatic resistance test (KS K ISO 811, hydraulic method) was carried out to check a resistance of a fabric to water leakage or wetting, a thermal resistance test (KS K 0466) to check an amount of power necessary to maintain a temperature of a fabric when a temperature difference occurs between two surfaces of the fabric, and a water vapor permeability test (KS K 0594, calcium chloride method) to check a degree of water vapor permeability of a fabric. Results of the mechanical tests and the functionality tests are as follows.
[Table] Test Items The present invention Comparison Example Tensile strength (N) Wale 235.1 237.4 Course 197.8 157.4 Tearing strength (N) Wale 31.6 18.9 Course 28.7 21.6 Bursting strength (kPs) 418 629 Peel strength (N/5.1 cm) 35 - Elastic recovery (%) Wale 90 90 Course 90 90 Air permeability (mm/s) 0.0 763.6 Hydrostatic resistance (cmH2 0) 730 12.3 Thermal resistance (clo) 0.092 0.165 water vapor permeability (g/m4 • 24 h) 888 9793 - As appreciated from the test results, it can be checked that the fabric according to the present invention and the fabric according to the comparison example have similar physical properties in the tensile strength, tearing strength, bursting strength, peel strength, and elastic recovery, but it can be also checked that the fabric according to the present invention has more excellent water and/or vapor permeability than the fabric according to the comparison example.
- Especially, the fabric according to the present invention has air permeability of 0.0 mm/s, which is remarkably excellent when compared with the fabric according to the comparison example. In detail, it can be appreciated that no air is permeated at all into the fabric according to the present invention. As described above, accordingly, the polyurethane is coated onto the given portion of the
clothing body 200 to allow theair tube 300 to be formed integrally with theclothing body 200, and the air introduced into theair tube 300 can be prevented from being discharged to the outside. -
FIG.7 is a perspective view showing a state where the air injection device is connected to the air tube in the functional clothing according to the present invention. - As shown in
FIG.7 , thefunctional clothing 500 further includes theconnector 400 adapted to connect theair tube 300 to the hose H. For example, theconnector 400 is coupled to one side of theair tube 300, and one end of the hose H is connected to theconnector 400, so that theair tube 300 can communicate with the hose H. In this case, the other end of the hose H connected to theconnector 400 is connected to the connectingpart 130 of theair injection device 100, so that theair injection device 100 can communicate with theair tube 300. - According to the present invention, the
connector 400 is thermally fused with theclothing body 200 as an integral body in a process of forming theair tube 300 and is thus coupled to theair tube 300. For example, theconnector 400 is located at a given area of theclothing body 200, onto which the polyurethane is coated, and in a process where the edges of the coated given area are thermally fused, theconnector 400 is thermally fused with one edge, so that theconnector 400 is coupled integrally with theair tube 300 in a state where at least a portion thereof is inserted into theair tube 300. - According to the present invention, further, the
connector 400 is configured to have a structure corresponding to the connectingpart 130 of theair injection device 100. Like the connectingpart 130 of theair injection device 100, for example, theconnector 400 includes a coupling member (whose reference numeral is not shown) and a fixing member (whose reference numeral is not shown) spaced apart from the outer peripheral surface of the coupling member, and if at least a portion of the coupling member of theconnector 400 is inserted into the hose H, one end periphery of the hose H is located between a gap between the coupling member and the fixing member of theconnector 400, so that theconnector 400 can communicate with the hose H. However, the structure of theconnector 400 is just one exemplary, and it may be freely changed according to embodiments of the present invention. -
FIG.8 is a perspective view showing an air injection device according to a second embodiment of the present invention,FIG.9 is an exploded perspective view showing the air injection device according to the second embodiment of the present invention,FIG.10 is a sectional view showing the air injection device according to the second embodiment of the present invention, andFIGS.11a and 11b are perspective views showing a body of the air injection device according to the second embodiment of the present invention. - In the same manner as the
air injection device 100 according to the first embodiment of the present invention as mentioned above with reference toFIGS.1 to 7 , anair injection device 1100 according to a second embodiment of the present invention is configured to communicate with theair tube 300 formed on theclothing body 200 and to thus allow air to be injected into or discharged from theair tube 300. In this case, an explanation on the same parts as theair injection device 100 will be avoided, and different parts will be described below. - Referring to
FIGS.8 to 11b , theair injection device 1100 includes abody 1110, an opening andclosing part 1120, a connectingpart 1130, and aninjecting part 1140. - The
body 1110 has anair passage 1112 formed therein, and both ends of thebody 1110 are connected to the opening andclosing part 1120 and the connectingpart 1130. Theair passage 1112 is open and closed according to a user's control for the opening andclosing part 1120. - The
body 1110 has aguide groove 1114 concavedly formed on an outer peripheral surface of one end thereof so as to guide the user's control for the opening andclosing part 1120. Also, the opening andclosing part 1120 has aguide protrusion 1124 protruding from the inner peripheral surface thereof in such a manner as to be inserted into theguide groove 1114. - The
guide groove 1114 includes afirst guide groove 1114a and asecond guide groove 1114b and athird guide groove 1114c that are extended from thefirst guide groove 1114a. For example, thefirst guide groove 1114a is formed on the outer peripheral surface of one end of thebody 1110 in an oblique direction from one end of thebody 1110 toward the other end of thebody 1110, and thesecond guide groove 1114b and thethird guide groove 1114c are extended from one end and the other end of thefirst guide groove 1114a in a circumferential direction of thebody 1110. - In this case, the
second guide groove 1114b and thethird guide groove 1114c are extended from both ends of thefirst guide groove 1114a toward the opposite sides to each other. For example, if thefirst guide groove 1114a is formed in an oblique line wherein one end (toward the opening and closing part 1120) is inclined toward a first rotating direction of the opening andclosing part 1120, thethird guide groove 1114c is formed in the first rotating direction from one end of thefirst guide groove 1114a, and thesecond guide groove 1114b is formed in a second rotating direction opposite to the first rotating direction from the other end (toward the connecting part 1130) of thefirst guide groove 1114a. - Accordingly, the
air injection device 1100 moves an opening and closing protrusion 1122 just through the rotations of the opening andclosing part 1120, thereby opening and closing theair passage 1112, as will be discussed later. - According to the present invention, further, at least one
locking protrusion 1115 is formed on at least one region of thesecond guide groove 1114b and thethird guide groove 1114c, respectively, to limit arbitrary rotations of the opening andclosing part 1120. - According to the present invention, further, the
guide groove 1114 further includes afourth guide groove 1114d so as to separate the opening andclosing part 1120 from thebody 1110. For example, thefourth guide groove 1114d is extended from a given area of thethird guide groove 1114c or from one end of thefirst guide groove 114a, from which thethird guide groove 1114c is extended, toward the opening andclosing part 1120. In this case, a limitation projection (whose reference numeral is not shown) is formed on at least a given area of thefourth guide groove 1114d to limit the arbitrary escape of the opening andclosing part 1120. - The
body 1110 has ascrew coupling portion 1116 and aninsertion portion 1118 formed on one end periphery thereof. Thescrew coupling portion 1116 is adapted to couple thebody 1110 to the connectingpart 1130, and theinsertion portion 1118 is inserted into the hose H. - The opening and
closing part 1120 is adapted to open and close theair passage 1112 of thebody 1110 by means of the user's rotating control. To do this, the opening andclosing part 1120 has the opening and closing protrusion 1122 protruding from the inner surface of one end thereof toward thebody 1110. The opening and closing protrusion 1122 is moved in a longitudinal direction of thebody 1110 by means of the user's rotating control and is thus inserted into theair passage 1112 or drawn from theair passage 1112, thereby closing or opening theair passage 1112 of thebody 1110. Further, the opening andclosing part 1120 has at least oneair injection hole 1126 penetratingly formed therein around the opening and closing protrusion 1122. - The connecting
part 1130 is coupled to the other end of thebody 1110 in such a manner as to allow theair injection device 1100 to communicate with theair tube 300. For example, one end periphery of the hose H connected to theair tube 300 is passed through a throughhole 1132 of the connectingpart 1130 to allow theinsertion portion 1118 of thebody 1110 to be fitted to the inside of one end periphery of the hose H, and in this state, if thebody 1110 and the connectingpart 1130 are screw-coupled to each other by means of ascrew coupling portion 1134 formed on the inner peripheral surface of the connectingpart 1130 and thescrew coupling portion 1116 formed on thebody 1110, the inner peripheral surface of the connectingpart 1130 pressurizes the outer peripheral surface of the hose H, thereby allowing the hose H to be fixed to theair injection device 1100. - The injecting
part 1140 is connected to one end periphery of the opening andclosing part 1120 to allow the user's air injection to be more easily carried out. So as to allow theinjecting part 1140 to be coupled to the opening andclosing part 1120, acoupling protrusion 1142 is formed on one end inner peripheral surface of the injectingpart 1140, and acoupling groove 1128 is formed on the outer peripheral surface of the opening andclosing part 1120. - If the
air passage 1112 is open, the interior of the injectingpart 1140 communicates with theair passage 1112, so that air is injected into theair injection device 1100 and theair tube 300 connected to theair injection device 1100 through the injectingpart 1140. - According to the present invention, further, the injecting
part 1140 includes amouth portion 1144 formed on the other end thereof. In this case, themouth portion 1144 has a smaller outer diameter than the opening andclosing part 1120. Accordingly, air blows into theair injection device 1100 more easily, in a state where themouth portion 1144 is fitted to the user's mouth. - The
air injection device 1100 as shown inFIGS.8 to 11b is just exemplary, and accordingly, it can be configured freely according to embodiments of the present invention. For example, the connectingpart 1120 and thebody 1110 are formed integrally with each other, the opening andclosing part 1120 and the injectingpart 1140 are formed integrally with each other, or at least one of thebody 1110, the opening andclosing part 1120, the connectingpart 1130, and the injectingpart 1140 is changed in position. -
FIGS.12a to 12c are perspective views showing operating methods of the air injection device according to the second embodiment of the present invention. - Referring to
FIGS.12a to 12c , theguide protrusion 1124 is moved along thesecond guide groove 1114b, thefirst guide groove 1114a, and thethird guide groove 1114c, sequentially through the user's simple control wherein the opening andclosing part 1120 rotates in the first rotating direction or in the second rotating direction opposite to the first rotating direction, so that theair passage 1112 can be open or closed. - For example, as shown in
FIG.12a , theair injection device 1100 is in a state where theair passage 1112 is closed by means of the opening and closing protrusion 1122. In this case, theguide protrusion 1124 is located on one end of thesecond guide groove 1114b that is formed toward the connectingpart 1130. - After that, if a given force from the user is applied to the opening and
closing part 1120 in the first rotating direction, theguide protrusion 1124 is moved over the lockingprotrusion 1115 and is then moved horizontally to the other end of thesecond guide groove 1114b connected to thefirst guide groove 1114a. - If the opening and
closing part 1120 is continuously rotated in the first rotating direction, as shown inFIG.12b , theguide protrusion 1124 is moved along the obliquefirst guide groove 1114a, and the opening and closing protrusion 1122 is moved in a direction distant from thebody 1110 and is thus drawn from theair passage 1112. - If the opening and
closing part 1120 is rotated further in the first rotating direction, as shown inFIG.12c , theguide protrusion 1124 reaches one end of thethird guide groove 1114c. Next, theguide protrusion 1124 is moved horizontally along thethird guide groove 1114c, is continuously moved over the lockingprotrusion 1115, and is fixed to the other end of thethird guide groove 1114c. - Through the rotating control, the
air passage 1112 is open to allow theinjecting part 1140 and the opening andclosing part 1120 to communicate therewith, and accordingly, air can be injected into theair tube 300 connected to theair injection device 1100. - If the opening and
closing part 1120 is rotated in the second rotating direction in the state where theair passage 1112 is open, theguide protrusion 1124 is moved along thethird guide groove 1114c, thefirst guide groove 1114a, and thesecond guide groove 1114b, sequentially, and accordingly, the opening and closing protrusion 1122 is inserted into theair passage 1112, thereby closing theair passage 1112. - As described above, the present invention has been disclosed with reference to the attached drawings. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims.
