DETAILED DESCRIPTION

(13) An embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, thicknesses of lines and sizes of constituent elements may be exaggerated for clarity and convenience in explanation.

(14) In addition, the embodiment disclosed hereinafter does not limit the scope of the present invention, but corresponds to merely exemplary terms of constituent elements presented in claims of the present invention, and the embodiments that include replaceable constituent elements as equivalents of the constituent elements defined in the overall specification and claims may be included in the scope of the present invention.

(15) FIGS. 1 to 7 illustrate a stopper 100 according to an embodiment of the present invention from many angles, in section.

(16) The stopper 100 includes a fixing hole 110 and a guide hole 120 into which a string is inserted.

(17) Preferably, the guide hole 120 is longer than the fixing hole 110, and the guide hole 120 and the fixing hole 110 are formed side by side to be adjacent to each other so as to reduce the entire volume.

(18) Based on the direction that a string 200 is inserted, an entrance and an exit of the fixing hole 110 are respectively arranged in the same direction as those of the guide hole 120. Because exits of the fixing hole 110 and the guide hole 120 are formed on the same side and the fixing hole 110 is shorter than the guide hole 120, a slope part 130 is formed from the entrance of the guide hole 120 to the entrance of the fixing hole 110.

(19) The slope part 130 has an inner space, and the inner space has a seating recess 111 on which a fixed end of the string 200 is positioned. The seating recess 111 is larger than a diameter of the fixing hole 110 so that a knot formed at the fixed end of the string 200 is seated on the seating recess 111.

(20) The slope part 130 has edge portions 131 formed at both outer lateral sides to protrude along borders of the outer lateral sides, so that a user can easily manipulate the string with the fingers.

(21) The fixing hole 110 has a support groove 112 formed at the outer face of the exit thereof to stably support the string 200.

(22) The diameter of the entrance of the guide hole 120 is larger than the inner diameter of the guide hole 120 so that the string 200 can be inserted into the guide hole 120 smoothly. The guide hole 120 has a first narrow groove 121 and a second narrow groove 122 which are respectively formed at the inside of the entrance and at the outside of the exit of the guide hole 120 and are formed in a V-shape.

(23) The stopper according to the embodiment of the present invention has three points on which pressure of the string is focused when the string is inserted into the stopper and is pulled. That is, as illustrated in FIG. 7, the stopper has a first point (a) at which the support groove 112 of the fixing hole 110 is located, a second point (b) formed at the inside of the entrance where the first narrow groove 121 of the guide hole 120 is located, and a third point (c) formed at the outside of the exit where the second narrow groove 122 of the guide hole 120 is located. The first to third points form a triangle to form a stable equilibrium.

(24) As illustrated in FIG. 8, the stopper 100 according to the embodiment of the present invention is used to fix and adjust the string 200 used for installing a tent 300.

(25) One end of the string 200 is connected to the tent 200 and the other end of the string 200 is caught to a fixing pack 310 which is fixed on the ground, so that tension of the string 200 can be adjusted using the stopper 100 mounted in the middle of the string 200.

(26) FIG. 9 illustrates a state where the string 200 is inserted into the stopper 100. Referring to FIG. 9, a knot 201 is formed at one end, namely, the fixed end of the string 200, and is inserted into the entrance of the fixing hole 110 of the stopper 100. Then, the knot 201 is seated and fixed on the seating recess 111. When a free end of the string 200 is inserted into the entrance of the guide hole 120 and is drawn out through the exit of the guide hole 120, so, the string 200 is combined with the stopper 100. The string 200 passing through the fixing hole 110 turns around the support groove 112 and enters the guide hole 120 so as to form a ring part 202 between the support groove 112 and the guide hole 120.

(27) Therefore, as illustrated in FIG. 8, the free end of the string 200 is connected and fixed to a ring of the tent, the ring part 202 is caught to the fixing pack 310, and then, the string 200 moves through the guide hole 120 of the stopper 100 to adjust the length of the string 200.

(28) As described above, when both ends of the string 200 are connected and pulled tightly, as illustrated in FIG. 10, the stopper 100 is reclined.

(29) That is, the string 200 is curved and pressed at the first point (a), the second point (b) and the third point (c) of the stopper 100 by power that pulls both end portions of the string 200, so that the string 200 can maintain the balance of power.

(30) The curved portions of the fixed end of the string 200 press the first point (a) by being guided to the support groove 112, press the second point (b) located inside the first narrow groove 121 while passing through the first narrow groove 121 when entering the guide hole 120 after turning around the ring part 202, and then, press the third point (c) located outside the second narrow groove 122 while getting out the exit of the guide hole 120 and passing through the second narrow groove 122.

(31) The curved portions of the string 200 press the three points forming a triangle in balance so that the string 200 can maintain the tightly pulled state as it is.

(32) Moreover, the first narrow groove 121 and the second narrow groove 122 are formed in a V-shape. The string 200 is inserted into the first narrow groove 121 and the second narrow groove 122 of the guide hole 120 while being curved and pressed, so that tension of the string 200 does not get loose easily even by external contact since the narrow grooves 121 and 122 hold the string 200 firmly.

(33) In the above state, in order to adjust tension or loosen the string, as illustrated in FIG. 11, when the user bends the stopper 100 back to adjust the directions of the guide hole 120 and the string 200, the pressed state of the string 200 and the stopper 100 is released so that the string 200 can freely move along the guide hole 120. When the user bends the stopper 100 in the opposite direction, the string 200 is curved and pressed at the three points again to be fixed.

(34) In the state where the stopper 100 and the string 200 are fixed, in order to release the string 200 by bending the stopper 100 back, when the user downwardly pushes the slope part 130 located at the lower portion of the stopper 100, because the fixed end of the string 200 is fixed on the seating recess 111 by the knot 201, the second point (b) and the third point (c) rotate around the knot 201, so that the string 200 is released.

(35) As described above, the fixed state of the string 200 can be released by the simple manipulation. Additionally, pushing the slope part 130 of the stopper 100, the user can accurately push and manipulate the stopper 100 without slip of the fingers since the edge portions 131 of the slope part 130 have stepped jaws.

(36) While the exemplary embodiment of the present invention has been described in more detail with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that the present invention is not limited to the exemplary embodiment and may be implemented in various forms without deviating from the spirit or scope of the invention. For instance, the entire shape of the stopper, or sizes or arrangements of the fixing hole and the guide hole may be changed according to the user's selection or as occasion demands.

(37) Furthermore, the stopper according to the embodiment of the present invention is applicable not only to strings used for a tent or a tarp but also to any object fit for the purposes of the present invention.
