Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a curtain runner for hanging a curtain suitable for frequently removing and washing a curtain in a hospital or a kindergarten.

[Prior art] As a conventional curtain runner of this kind, for example,
There is one described in Japanese Utility Model Publication No. 1-30144.

This thing, a car is attached to the upper side of the upright frame-shaped body, a vertical hole is made in the lower side, and a flange and a cut are provided in the upper and lower ends respectively, and a bush cylinder in which the inner diameter of the top is reduced is fitted,
The bush cylinder is characterized in that a hanging rod having a bulge part having a diameter larger than the inner diameter of the top part and having a curtain mounting part provided below is inserted therethrough.

Such a curtain runner can be assembled by first inserting the bush cylinder into the frame of the main body from the side, and then pushing the bush cylinder downward to fit the bush cylinder into the vertical hole. In this case, the upper and lower ends of the bush cylinder are provided with flanges. However, since the corresponding portions are also provided with slits, the collars can be reduced in diameter by these splits and inserted into the vertical hole. And

On the other hand, when removing the hanging rod from the bush cylinder, it can be performed by pushing the bush cylinder upward and pulling the hanging rod downward in this state. In this case, when the bush cylinder is pushed upward, the bending deformation to the outside of the upper collar portion becomes possible, and in this state, by pulling the hanging rod downward, the bulging portion bends the small diameter portion outward to deform the small diameter portion. The lifting rod is disengaged from the bushing cylinder.

[Problem to be Solved by the Invention] However, in such a conventional curtain runner, since the work of removing the hanging rod must be performed by moving the bush cylinder upward, the removal operation is performed by an unskilled person. This has been a troublesome operation, and there has been a problem that the curtain cannot be easily washed.

In other words, the push-up of the bush cylinder is performed by pinching the lower flange portion. Not only is the collar portion itself small, but also when the bush tube is pushed upward, it comes into contact with the lower side of the upright frame-shaped body to maintain the push-up state. Therefore, it is difficult to pull the hanging rod downward with the bush cylinder pushed up.

The present invention has been made in view of such a conventional problem, and eliminates a moving member such as a conventional bush cylinder, and adopts a structure in which a hanging rod can be removed simply by pinching a runner body. It aims to solve the problem.

[Means for Solving the Problems] In order to achieve the above object, a curtain runner according to the present invention is configured such that a tree rod for suspending and supporting a curtain is detachably attached to a runner body movable by being guided by a curtain rail. The runner main body has a first main body piece and a second main body piece having upper portions fixed to each other and having flexibility at opposing lower portions. Are provided with overlapping parts vertically overlapping each other,
Each overlapping portion has a long hole that cooperates with a through hole whose inner diameter can be changed and an edge protrusion that is inserted into the long hole on the other side so as to border a part of the periphery of the through hole. Provided,
The nail bar has a head portion having a diameter larger than a minimum diameter of the through hole at an upper portion.

[Operation] In the case where the stick rod is incorporated in the runner body, the stick rod is formed in a through hole formed by the long hole provided in the overlapping portion of the first body piece and the long hole provided in the overlapping portion of the second body piece. It can be done easily by inserting the head of In this case, the first main body piece and the second main body piece are fixed to each other at their upper parts and each lower part is provided with flexibility, so that the head of the tree rod is pressed into the through hole. As a result, the through-hole is expanded, whereby the inner diameter of the through-hole becomes wider than the outer diameter of the head. Therefore, the strip bar can be easily attached to the runner body only by pressing the head into the through hole.

Also, when removing the filer rod from the runner main body, grip each lower part of the first main body piece and the second main body piece and bend them in a direction to bring both main body pieces closer to each other to change the diameter of the through hole to the outer diameter of the head. By making the head wider than that, and pulling out the head from the through hole in that state, the strip bar can be easily removed from the runner body.

[Example] Next, an example of the present invention will be described with reference to the drawings.

It is the figure applied to the runner main body of the type provided with the roller which rolls inside the curtain rail.

First, the structure will be described. As shown in FIGS. 1 and 2, 1 is a runner main body, 2 is a tree rod, and 3 is a curtain rail. The runner main body 1 includes a first main body piece 4 and a second main body piece 5,
It is composed of rollers 6 and a support shaft 20 for rotatably supporting both rollers 6.

The first main body piece 4 is shown in FIGS. 3 and 4 (a) to (c).
As shown in detail in FIG. 1, the side surface shape is a crank shape, and a groove 7 extending vertically is provided inside the upper part. A bearing hole 8 penetrating in the lateral direction is provided in the center of the groove 7, and a positioning stopper 9 for positioning is provided below the groove 7. Further, a laterally extending overlapping portion 10 is provided inside the lower portion of the first main body piece 4, and the overlapping portion 10 is provided with a horizontally extending elongated hole 11, and the upper surface of the overlapping portion 10 In addition, a crescent-shaped rim 12 is provided at the tip of the elongated hole 11.

The second main body piece 5 is shown in FIGS. 5 and 6 (a) to (d).
As shown in detail in the drawing, the longitudinal cross-section is in the shape of a crank, and a dovetail 13 extending vertically is provided inside the upper part, and a bearing hole penetrating in the lateral direction is provided in the central part of the dovetail 13.
14 are provided. The dovetail 13 can be fitted with the dovetail 7 of the first body piece 4, and the fitting fixes the upper parts of the first body piece 4 and the second body piece 5.

Further, on the inner side of the lower part of the second main body piece 5, there is provided an overlapping portion 15 extending in the lateral direction. The overlapping portion 15 has a U-shaped vertical cross-section opening downward, and the overlapping portion 10 of the first main body piece 4 is slidably fitted in the concave portion. The overlapping portion 15 is provided with a long hole 16 extending in the lateral direction,
An arc-shaped edge projection 17 is provided on the lower surface of the overlapping portion 15 and at the tip of the long hole 16.

Thus, when the first main body piece 4 and the second main body piece 5 are combined, the tip portions of both the overlapping portions 10 and 15 are vertically overlapped and the elongated holes 11 and 16 provided in the respective portions are overlapped. The tips also overlap, and the long holes 11, 16 cooperate to form a through hole 18 whose inner diameter can be changed.

As a material of the first main body piece 4 and the second main body piece 5, a flexible material such as, for example, an acetal resin is preferable in order to make each opposing lower part flexible. However, as well as other synthetic resins, a metal material or the like can be used as long as the lower portion has flexibility. Reference numeral 19 denotes a concave portion provided on the outer surface of the main body pieces 4 and 5 so as to be convenient for pinching the main body pieces 4 and 5.

In a state where the first main body piece 4 and the second main body piece 5 are combined, the two bearing holes 8 and 14 are set coaxially, and the support shaft 20 penetrates both the bearing holes 8 and 14. doing. The rollers 6 are attached to the protruding ends on both sides of the support shaft 20, so that the rollers 6 are rotatably supported on the upper portion of the runner body 1.

As shown in FIGS. 1 and 2, the tree bar 2 is substantially U-shaped, and has a head 22 at the upper end of one support piece 21. As shown in FIG. The head 22 has a conical shape with a rounded upper end, and a step between the head 22 and the shaft is set by making the diameter of the base larger than the diameter of the shaft. The diameter of the head 22 is smaller than the width of the long holes 11, 16, and
The through hole 18 formed by the elongated holes 11 and 16 is set to be larger than the minimum diameter in the natural state.

Further, the other hooking piece 23 of the strip bar 2 has a step portion 24 set inside by reducing the diameter of the upper end. A retaining piece 25 provided in the middle of the shaft portion of the support piece 21 faces the step portion 24, and the retaining piece 25 and the step portion 24 prevent the curtain B from coming off.

 Next, the operation will be described.

The runner body 1 of the curtain runner A having the above configuration can be assembled, for example, as follows.

First, the overlapping portion 10 of the first main body piece 4 and the second main body piece 5
And the dovetail 13 of the second main body piece 5 is fitted into the groove 7 of the first main body piece 4 from above, and is inserted until the dovetail 13 is in contact with the stopper 9.
As a result, the overlapping portion 15 of the second main body piece 5 is superimposed on the overlapping portion 10 of the first main body piece 4, and the through holes 18 are formed by the overlap of the elongated holes 11 and 16 provided in the respective overlapping portions 10 and 15. Is formed.

Next, the first fixed by the dovetail as described above
And a support shaft 20 previously rotatably supporting one roller 6 is inserted into bearing holes 8 and 14 in the upper portions of the second main body pieces 4 and 5, and another one end is inserted into the tip of the support shaft 20. The roller 6 is rotatably supported. Thereafter, the runner body 1 is completely assembled by preventing it from coming off by means of caulking or the like.

Such a runner body 1 has a required number of curtain rails 3.

This can be easily performed by inserting the head 22 of the file rod 2 from below into the through hole 18 formed by the long hole 16 provided in the above.

In this case, since the first main body piece 4 and the second main body piece 5 are formed of a flexible member such as a synthetic resin in order to make each lower part flexible, the head of the tree rod 2 is formed. Department
By pressing the 22 into the through-hole 18, the through-hole 18 is expanded, and the inner diameter becomes larger than the outer diameter of the head 22. Therefore, the nail bar 2 can be easily attached to the runner body 1 simply by pushing the head 22 into the through hole 18.

At this time, the through holes 18 are overlapped with the overlapping portions 10, 1
Because it is formed by a combination of five long holes 11, 16,
The head 22 is obliquely guided by the step between the two overlapping portions 10 and 15 as it is, but in the present embodiment, the length of the overlapping portion 10 located below is provided on the lower surface of the overlapping portion 15 located above. Since the edge projection 17 that enters the hole 11 is provided, and the edge projection 17 borders a part of the lower edge of the through hole 18 to eliminate the step, the head 22 can be guided vertically. it can. Therefore, the pressing force applied from the head 22 to both the overlapping portions 10 and 15 can be applied uniformly, and therefore, the first and second main body pieces 4 and 5 are elastically deformed with a small pressing force, and 2 can be easily inserted.

Similarly, in the present embodiment, the overlapping portion
On the upper surface of 10, there is provided an edge projection 12 which enters the long hole 16 of the overlapping portion 15 located above, eliminates a step between the edge projecting portion 12 and the overlapping portion 15, and supports the entire lower surface of the head 22. As a result, the tree rod 2 can be supported vertically and can be reliably supported by a large area.

On the other hand, when removing the filer rod 2 from the runner main body 1, the lower portions of the first main body piece 4 and the second main body piece 5 are pinched to bend in a direction in which both main body pieces 4, 5 are brought closer to each other. The inner diameter is made wider than the outer diameter of the head 22. In this state, the head 22 is pulled out of the through hole 18 by pulling the tree bar 2 downward,
The strip bar 2 can be easily removed from the runner body 1.

FIGS. 8 to 10 show another embodiment of the runner body according to the present invention. The runner body has a sliding projection having a sliding surface for sliding inside the curtain rail.
