Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a traction wire used in traction therapy.

[0002]

[Prior art]

 Traction therapy is widely applied as a conservative therapy for lumbar and cervical spine diseases. Figure 3 shows the lumbar traction. Before the treatment, the patient 35 is fitted with the waist brace 34 and the side brace 36, the waist brace 34 is connected to the hanger 33, further connected to the tow wire 32, and the tow wire 32 is wound by the tow device 31. And perform traction treatment.

The towing wire 32 and the hanger 33 are frequently connected and disconnected, so that they can be easily attached and detached, and must be kept from being detached when connected.

FIG. 4 shows an example of a conventional towing wire. (A) of the figure is a side view, and (B) is a front view. This is disclosed in Utility Model Registration Publication No. 2578726, in which a hook 44 is connected to the tip of a wire 46 coated with a resin 45, and a stopper 47 is attached. The hook 44 includes a main portion 41, a traction hook portion 42 in which the front end of the main portion 41 is formed in a U-shape, and a stopper for pivotally supporting a stopper 47 and extending toward the front end of the hook portion 42. The device for preventing disengagement comprises a guard plate 43, a pin 48 for attaching the guard plate 43 to the main portion 41, and a spring 49 for pressing the guard plate 43 against the hook portion 42. The stopper 47 prevents the hook 44 from dropping into the traction device.

In the utility model of the prior application, a hole is formed in the stopper 47, the guard plate 43 is rotatably attached to the hole by a pin 48, and the guard plate 43 is pressed against the tip of the hook 42 by a spring 49. . When the guard plate 43 is pushed in the direction of the arrow, the towing wire can be attached to and detached from the hanger 33. When the hanger 33 is connected and the hand is released from the guard plate 48, the guard plate 43 is attached to the hook portion 42 by the spring 49. The hanger 33 does not come off the hook because it is pressed against the tip.

[0006]

[Problems to be Solved by the Invention] Conventionally, towing wires such as the utility model in the prior application have been used, and all of them have been used without any practical problems. However, the conventional tow wire had to make a hole in the stopper 47 and fix the guard plate 43 with a pin 48 together with a spring 49 there. This increased the number of parts, and the processing and assembly was cumbersome, time-consuming and costly. The present invention relates to an improvement of the utility model of the prior application, and aims to provide a simple, reliable, and inexpensive towing wire with a reduced number of parts and reduced processing and assembly man-hours.

[0007]

[Means for Solving the Problems]

 In order to solve this problem, according to the present invention, a main part 1, a hook part 2 having a tip of the main part 1 formed in a U-shape, and a tip end of the hook part 2 which is pivotally supported by the main part 1. A hook 4 is constituted by the passed stopper device 3 and a towing wire in which a wire 6 coated with a resin 5 is connected to the hook member 4, a spring in which the stopper device 3 is formed as one body. It was composed of wood. The retaining device 3 is usually attached so as to be in contact with the tip of the hook portion 2, and when the retaining device 3 is pushed inside the hook 4 as shown in FIG. When the hanger 33 can be attached and detached and this force is eliminated, the device 3 comes back to its original position by its own spring force, comes into contact with the tip of the hook 2, and the towing hanger 33 cannot be attached or detached. .

[0008]

[Action]

 The hook 4 of the present invention has a main part 1, a hook part 2, and a detachment prevention device 3, and the detachment prevention device 3 is composed of a single spring material having a spring property. You. This hook 4 usually forms a ring closed spatially by the main part 1, the hook part 2, and the detachment prevention device 3 as shown in FIG. 1 (A). As described above, when the device 3 for preventing disengagement is pushed into the hook 4 in the direction of the arrow, the hanger 33 can be detached from the opening. When the hand is released, the detachment prevention device 3 returns to its original state by its own spring force, forms a closed ring with the hook portion 2 and the detachment prevention device 3, and the hanger 33 cannot be detached. As described above, the tow wire of the present invention has a simple structure as compared with the conventional product, and has the same function as the conventional product.

[0009]

【Example】

 FIG. 1 is an embodiment of the present invention. The towing wire is connected to a hook 4 attached to a wire 6 coated with a resin 5, and the hook 4 is attached to the main part 1, a hook part 2 having a U-shaped tip, and a main part 1. The hook preventive device 3 is provided with a slip-off preventing device 3 extending over the tip of the hook portion 2. The slip-off preventing device 3 is made of an integrally molded material, and is provided with a stopper 7. That is, the present invention is an improvement of Utility Model Registration Publication No. 2578726.

As shown in FIG. 1D, the detachment preventing device 3 forms a wire rod, inserts it into a hole provided in the main part 1, and contacts the distal end of the hook 2 with the distal end of the wire. Has been installed. FIG. 1E is a side view of FIG. As shown in the figure, the holes provided in the main portion 1 are provided at shifted positions, so that the wire acts as a spring material. Normally, the hook 4 of the towing wire is formed in an annular shape with the main part 1, the hook part 2, and the detachment prevention device 3. As shown in FIG. 1C, when the detachment prevention device 3 is pushed inward (in the direction of the arrow) of the hook 4, the detachment prevention device 3 and the hook portion 2 are separated, and the hanger 33 can be detached from the opening. . When the hand is released, the detachment prevention device 3 returns to its original position by its own spring force and comes into contact with the tip of the hook portion 2, so that the connected towing hanger 32 cannot be detached.

In the present invention, a hook 4 for a towing wire is constituted by a main part 1, a hook part 2, and a detachment prevention device 3, and the detachment prevention device 3 uses a spring material integrally formed. The tip comes into contact with the tip of the hook part 2 and the towing hanger 32 can be attached and detached by pushing the detachment prevention tool inward. For this reason, the detachment prevention device 3 may be any device as long as it is a spring material integrally formed. An integrally molded spring material is a material that has been integrally molded in advance and can be easily inserted or screwed into a spring material installation site (hole in the above description), as shown in FIG. 1 (C). It has the function of a spring that returns to the original position when the hand is released after bending the member. FIG. 1 shows an example in which a wire is formed, but the wire diameter and material are not limited, and the shape and size to be formed are not limited. Further, the position and shape of the hole for attaching the spring material or the shape of the attachment portion of the spring material to the main part 1 are variously conceivable, but may be any.

FIG. 2 shows another embodiment of the present invention. FIG. 2A is an example of a spring material obtained by processing a plate material, and FIG. 2C is a diagram in which the spring material is mounted on a hook for a towing wire. The shape, size, material, method of attaching to the main part, and the like of the plate are not limited. FIG. 2 (B) is an example of a spring material in which a wire rod is attached to a bar material, and FIG. 2 (D) is a diagram in which this is mounted on a tow wire. Again, the shape, dimensions, material, and method of attachment to the main part of the plate are not limited. In the above description, the example in which the detachment preventing device 3 is attached so as to be inscribed in the hook portion 2 has been described, but it may be circumscribed.

[0013]

[Effect of the invention]

 It has a simple structure, is easy to assemble, has the same functions as the conventional one, and is easy to handle. Therefore, it is possible to reduce material costs, parts processing costs, and assembly man-hours, and to provide an inexpensive towing wire.
