Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a draw runner for hanging a curtain draw string of a curtain.

[0002]

[Prior art]

 A drawstring runner for hooking a drawstring of a curtain in loop form is known from Japanese Utility Model Publication No. 62-7188. This publicly known runner consists of left and right wheels and a main body that supports the wheels. A loop drawn from a draw string that passes through the curtain rail is drawn into a string passing hole that is integrally provided in the center of the runner body, and then the loop. It was a method to hang it on the string fixing part in the lower center of the runner body.

[0003]

[Problems to be solved by the device]

 The runner body of the string runner extends in the longitudinal direction of the curtain rail, and wheels running inside the curtain rail are attached to both ends of the runner body. The relative position of the provided string passage hole is always constant, but in the curved area of the curtain rail, the relative position between the string passage hole of the runner body and the drawstring in the curtain rail changes. For this reason, there was a problem that the runner body was pulled by the drawstring and the wheels came off the running surface of the curtain rail, which made it difficult to open and close the curtain.

The present invention has been made in order to solve this problem, and an object of the present invention is to make the wheels of the curtain pulling runner deviate from the wheel running surface of the carten rail even in the curved area of the curtain rail. The purpose is to provide a fearless string runner.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the means adopted by the present invention is to open a string through hole in the string receiver, and attach the string receiver to the center of the runner body slidably in the direction orthogonal to the longitudinal direction of the curtain rail. The receiver was loosely fitted into the slit in the cord room through which the drawstring of the curtain rail passed.

[0006]

[Action]

 Since the wheels of the string runner are located on both sides of the main body that extends in the longitudinal direction of the curtain rail, the center of the main body draws a curve different from that of the curtain rail when traveling in the curved area of the curtain rail, so the curtain rail runs from the main body of the runner. The distance to the string fixing part in the lower center changes, but the string receiver with the string guide loosely fitted in the slit of the string chamber slides in the direction orthogonal to the longitudinal direction of the curtain rail with respect to the runner body and always draws. Even if the runner's relative position with respect to the drawstring fluctuates, the length of the drawstring loop from the string receiving hole of the cord receiver to the cord fixing part of the runner body hardly changes because it runs along the cord chamber. Therefore, there is no risk that the wheels of the runner body will come off the running surface of the curtain rail due to the drawstring.

[0007]

【Example】

 The device of the present invention will be described based on an embodiment shown in the drawings. As shown in FIGS. 1 to 3, the curtain rail 10 has a string chamber 13 on both sides of the lower opening 11 through which a draw string 12 is passed. A slit 14 is opened on the lower surface of the cord chamber 13, and the front and rear width of the slit 14 is smaller than the outer diameter of the drawstring 12, but the drawstring 12 is easily slit by elastically deforming its cross section. It can be put into the cord room 13 from 14. The synthetic resin main body 20 of the stringing runner is provided with wheels 21 on its top, and the wheels run on rails 15 inside the curtain rail.

The lower part of the main body 20 is suspended from the opening 11 of the curtain rail 10 by sandwiching the lower part of the main body 20 from the front and rear with metal plates 22 and 23, and is fixed by two right and left bolts 24 and 25. One plate 22 is provided with hook holes 26 for hooking curtain hooks on its left and right ends. A front and rear guide roll 27 is rotatably attached to one of the bolts 24, and the guide roll is placed along the slit 14 on the lower surface of the cord room 13 of the carten rail.

The other plate 23 is integrally formed with two string receiving portions 28 protruding in the front-rear direction. A synthetic resin string receiver 30 is arranged between the two string receivers 28 so as to be slidable in the front-rear direction. The string receiver 30 has slide grooves 29 on both left and right sides, and the slide grooves are slidably fitted in the two string receivers 28. Rod-shaped cord guides 31 are integrally erected on the right and left sides of the upper surface of the cord receiver 30, and left and right cord passage holes 32 are formed between the left and right cord guides 31. The left and right string guides 31 are loosely fitted in the slits 14 of the string chamber 13. Since the main body 20 is kept in a stable posture by the wheels 21 and the guide rolls 27 along the curtain rail 10, there is no possibility that the string guide 31 will come off the slit 14 of the string chamber 13.

A string fixing portion 35 is integrally provided at the lower center of the main body 20, and a string hooking groove 36 and a string fixing hole 37 are provided in the string fixing portion 35. The loop 12a of the drawstring 12 that hangs from the one cord chamber 13 of the curtain rail 10 along the cord guide 31 passes through the cord passing hole 32 of the cord receiver 30 and is hooked in the cord hooking groove 36 of the cord fixing portion 35 to be fixed. To do. In the linear area of the curtain rail, the relative position of the string fixing portion 35 of the main body 20 with respect to the curtain rail 10 is constant, but in the curtain rail curved area, the relative position of the main body 20 with the string fixing portion 35 with respect to the curtain rail 10. It fluctuates in a direction orthogonal to the longitudinal direction of the curtain rail. However, since the cord guide 31 of the cord receiver 30 is fitted in the slit 14 of the cord chamber 13 of the curtain rail 10, it cannot be displaced together with the main body 20, so that the cord guide 31 is moved along the slide groove 29 of the cord receiver 28. It slides in the direction perpendicular to the longitudinal direction of the curtain rail. As a result, even if the relative position of the cord fixing portion 35 of the main body 20 with respect to the cord chamber 13 changes, the length of the loop 12a from the cord chamber 13 to the cord fixing portion 35 through the cord passing hole 32 hardly changes. Therefore, there is no possibility that the loop 12a will be strained and the main body 20 will be pulled in the direction orthogonal to the longitudinal direction of the curtain rail to disengage the wheel 21 of the runner from the wheel running surface of the curtain rail 10.

[0011]

[Effect of device]

 As described above, the string runner of the present invention is different from the conventional one in which the string through hole for pulling in the loop of the drawstring is provided integrally with the main body of the runner. The main body is slidable in the direction perpendicular to the longitudinal direction of the curtain rail, and its cord receiver is always along the slit of the cord room through which the draw cord passes. Even if the relative position of the runner body on the curtain rail changes in the direction orthogonal to the longitudinal direction of the curtain rail, the loop length of the drawstring hanging on the runner body hardly changes. It has an excellent effect of preventing the wheels from being removed from the running surface of the curtain rail.
