MODE FOR INVENTION

[0026] Hereinafter, a drawing-in/out device for a rescue wire for a waist belt according to embodiments of the present invention is described in detail with reference to the accompanying drawings.

[0027] FIG. 1 is a perspective view showing a partial and exploded part of a drawing-in/out device for a rescue wire for a waist belt according to an embodiment of the present invention. FIGS. 2a and 2b are a plan view showing the state in which the drawing-in/out device for a rescue wire for a waist belt has been coupled and a front view thereof. In the present invention, when a fixture 20 including a clamp 21 is connected to a support 11 provided in a buckle 10 and a strap S formed of a strip of leather or fabrics so that the fixture and the strap are inserted and fixed to the fixture, the support, the fixture and the strap are coupled through the medium of a connection tool 30 on which a wire W capable of lifesaving is mounted to be drawn out or rewound.

[0028] A hook 22 having a cut groove 23 is formed in the middle of the fixture 20 to which the strap S is inserted and fixed so that the hook is caught in the latching part 34 of the connection tool 30 neighboring the fixture. A safety plate 24 for maintaining a closed state by the tension of a spring is provided at the entrance of the hook 22 so that the latching part 34 received within the hook is not randomly detached from the hook.

[0029] A depressed space 39 is formed within the connection tool 30. After a reel R on which the wire W having a length and tension capable of lifesaving has been wound is disposed in the depressed space 39, the reel and the depressed space are coupled and shielded by a cover 31. In this case, a shaft 33 supporting the reel R so that the reel is rotatable is formed through the reel. A handle part 32 having a handle 32 in such a way as to be folded or unfolded based on a hinge 33 is coupled to a portion of the shaft 33 externally protruded from the shaft.

[0030] The handle 32 formed at the end of the handle part 32 is folded to the other side based on the hinge 33 when the drawing or winding operation of the wire W is completed. Accordingly, as shown in FIG. 2b, the handle 32 is inserted into any one groove formed at the edge of the cover 31, thereby functioning as a stopper for stopping the rotation of the shaft 33 while preventing the exposure of the handle.

[0031] The end of the wire W drawn out from the reel R is fixed to the middle of the latching part 34 disposed adjacent to a through hole 37 formed on the side of the connection tool 30 via the through hole 37. The latching part 34 includes latching protrusions 34 to at least one side of which an elastic force of the spring is applied. When the latching part 34 presses the latching protrusions 34 in the state in which they have been inserted and fixed to the upper and lower latching holes 38 of the connection tool 30, the latching part 34 is detached from the latching holes 38, so the wire W wound on the reel R is drawn out.

[0032] In this case, each of the outsides of the latching holes 38 formed at the top and bottom of the connection tool 30 may be processed in the form of a wedge groove so that they can easily press the latching protrusions 34 inserted thereto, as in the partial enlarged view of FIG. 2b.

[0033] A hook 35 having a cut groove 35 formed in a middle thereof so that the support 11 provided in the buckle 10 is caught in the hook is formed on the other side of the connection tool 30. A safety plate 36 for maintaining the closed state by the tension of a spring so that the support 11 received in the hook is not randomly detached is provided at the entrance of the hook 35.

[0034] When the latching part 34 is caught in the cut grooves 23 and 35 formed in the hook 22 provided in the fixture 20 and the hook 35 provided in the connection tool 30, respectively, the cut grooves 23 and 35 are used as the passages of the wire W fixed to the central part of the latching part, thereby facilitating a connection task. The safety plates 24 and 36 provided at the entrances of the respective hooks 22 and 35 are open when the latching part 34 and the support 11 to be caught enter the safety plates 24 and 36 or apply a force so that the elastic force of the spring is artificially offset, and then maintain the closed state when the elastic force of the spring acts on them. Accordingly, the latching part 34 and the support 11 confined in the hooks 23 and 35 are not randomly separated.

[0035] A guide member 40 is disposed on one side of the depressed space 39 and closely attached to the wire with applying an elastic force of a sheet spring form to the wire from the outside of the wire W wound on the reel R on the upper and lower sides to the inside, and controls the drawing and winding operation of the wire. When the cover 31 is fixed using bolts, the guide member 40 may be supported by a plurality of protruded jaws 39 formed in the depressed space 39 so that the bolts are screwed onto the cover in order to prevent the guide member from hindering the drawing or winding operation.

[0036] That is, the guide member 40 is closely attached to the outside of the wire W wound on the reel R on the upper and lower sides by the elasticity of the sheet spring. Accordingly, a so-called backlash phenomenon in which the wire is tangled when the rotation of the reel R becomes faster than the drawing-out speed of the wire W while the wire W is drawn out can be prevented, and a twisting phenomenon generated when the wire is rewound can be prevented.

[0037] FIG. 3 is a front view showing the state in which the wire has been drawn out. When an emergency situation is generated in the state in which a user has worn a belt equipped with the drawing-in/out device for a rescue wire according to the present invention, the user releases the constrained state of the handle 32 of the handle part 32 closely attached to the cover 31 on the back side of the connection tool 30 by releasing the belt so the shaft 33 of the reel R on which the wire W has been wound is rotatable. Next, the user presses the latching protrusions 34 of the latching part 34 coupled to the latching holes 38 at the top and bottom of the connection tool 30, so the latching part 34 is detached from the latching holes 38. Accordingly, the wire W wound on the reel R, together with the fixture 20 to which the strap S has been fixed, is drawn out to a required length and used for rescue.

[0038] When the rescue is terminated in the state in which the wire W has been drawn out from the reel R disposed in the connection tool 30, the shaft 33 is rotated in the winding direction using the handle 32 of the handle part 32 so that the drawn wire W is rewound on the reel R. When the handle part 32 is folded in the opposite direction based on the hinge 33 in the state in which the winding operation has been completed, the handle 32 provided at the end of the handle part 32 is inserted into any one of the holes formed in the cover 31 and constrained thereby. Accordingly, the drawing of the wire W is stopped and the wire is used for a next opportunity.

[0039] FIGS. 4a and 4b are a plan view of a modified example of the drawing-in/out device for a rescue wire for a waist belt and a front view thereof. FIG. 5 is a front view showing the state in which the wire has been drawn out from the modified example of FIG. 4b. In the previous embodiment, the belt in which the support 11 provided in the buckle 10 and the fixture having the strap S inserted and fixed thereto have been connected through the medium of the one connection tool 30 has been described. In contrast, the present embodiment illustrates a belt in which another connection tool is continuously connected between the support 11 of the buckle 10 and the connection tool 30 connected in the previous embodiment or between the fixture 20 to which the strap S has been inserted and fixed and the connection tool 30 connected in the previous embodiment in the state in which two or more connection tools 30 have been prepared. Accordingly, a case where rescue is insufficient using the wire W provided in one connection tool 30 can be handled because the wire W of a sufficient length is secured.

[0040] That is, the belt is configured by continuously connecting the plurality of connection tools 30 in the process of interconnecting the support 11 provided in the buckle 10, the hook 35 and the latching part 34 respectively provided on both sides of the connection tool 30, and the hook 22 of the fixture 20 to which the strap S has been fixed. Accordingly, when the configured belt is worn, the end part of the strap S settled through the inside of the buckle 10 and fixed to the buckle 10 maintains the state in which the front of the one or more connection tools 30 and the fixture 20 are covered. As a result, an external appearance and marketability according to the wearing of the belt can be improved because elements, such as the connection tool 30 and the fixture 20 of the strap, other than the buckle 10 are concealed.

[0041] FIG. 6 is an exploded perspective view of a drawing-in/out device for a rescue wire for a waist belt according to another embodiment of the present invention. FIGS. 7a and 7b are a front view showing that part of FIG. 6 has been enlarged and a front view showing the state in which a wire for lifesaving has been drawn out. The present embodiment relates to an embodiment in which the decoration of a buckle 10 has a hanger loop form, a reel R having a wire W wound thereon is disposed within a connection tool 30, and a strap S has been settled.

[0042] A hook 35 has been formed on one side of the connection tool 30, and a support 11 provided the buckle 10 has been inserted into the hook. In this state, the support 11 is constrained by a fixing plate 35a coupled by bolts. Latching holes 38 are formed over and under the buckle 10 on the other side of the buckle 10. A latching part 34 having an elastic protrusion 34 is coupled to the latching holes 38 in such a way as to be inserted or detached. The strap S is settled in the latching part 34 in the state in which the front end of the wire W has been fixed to the strap.

[0043] In order to mount the reel R having the wire W wound thereon on a depressed space 39 formed by a cover 31 coupled to the back side of the connection tool 30, a shaft hole 39a is formed to penetrate the front and back of the depressed space 39, a short shaft R1 provided on both sides of the reel R is rotatably coupled to the shaft hole, and the wire W wound on the reel R is drawn out to the outside of the depressed space 39 through a through hole 37 formed in the middle of the connection tool 30 on one side thereof. Accordingly, when rotary power is applied to the reel R by a force applied when the wire W is drawn, the short shaft R1 provided on both sides of the reel is supported by the shaft hole 39a penetrating the depressed space 39 and rotated.

[0044] A hole R2 through which the reel R is rotated by a dedicated tool and a long groove R3 rotated using a simple tool, such as a coin or driver, are formed in parallel on the center line of the short shaft R1. A guide member 40 is disposed on one side of the depressed space 39. The guide member is closely attached in the state in which it has applied an elastic force of a sheet spring form from the outside of the wire W wound on the reel R on the upper and lower sides thereof to the inside, thus controlling the drawing and winding operation of the wire.

[0045] Accordingly, in the reel R rotatably supported by the shaft hole 39a within the depressed space 39 provided in the connection tool 30, means for rewinding the drawn wire can be rewound by an externally coupled tool using the hole R2 or long groove R3 of the short shaft R1 exposed to the outside of the buckle. Accordingly, the buckle can be fabricated simply and compactly compared to a conventional technology.

[0046] Accordingly, after the elastic protrusion 34 is detached from the latching holes 38 at the top and bottom of the connection tool 30 on one side thereof, when the strap S settled in the latching part 34 is separated from the elastic protrusion, the wire W having the front end fixed to the latching part 34 is drawn out from the reel R disposed in the depressed space 39 of the connection tool 30. Accordingly, the wire can be used for lifesaving or in an emergency situation.

[0047] In the above embodiments, the front end of the wire W has been illustrated as being fixed to the latching part 34. For example, the front end of the wire W drawn out to the outside of the depressed space 39 through the through hole 37 may form a knot in such a way as to be not returned to the through hole 37, and may be drawn separately from the latching part 34.
