Description

[Detailed explanation of the invention] A. Purpose of the invention a. Field of industrial application This invention is a runner for adding a curtain rail, in particular, a vertical runner with grooves for engaging rolling wheels on both sides, and a rail portion on each side. This invention relates to an additional runner used for a curtain rail with an I-shaped side surface.

b. Prior Art Conventionally, runners used for curtain rails having an I-shaped vertical side surface as described above generally have a U-shape when viewed from the side.
It had a one-piece molded body with rolling wheels pivotally supported on both insides. In order to attach the runner to the curtain rail, both inner rolling wheels were engaged from the side ends of the curtain rail.

Note that, unlike a curtain rail with an I-shaped vertical side surface using the additional runner of the present invention, a runner for a so-called square rail with an inverted U-shaped vertical side surface with a runner engagement groove opened at the center of the bottom can be used, for example. There was one described in Utility Model Application Publication No. 59-194891.

This is placed approximately in the center of the vertically long board, with a width of 2
A notch with a length of 1/2 is formed, and a protrusion with the same vertical length as the notch is formed on one side of the remaining 1/2, and an additional protrusion is formed on the protrusion. A wheel is pivoted on the upper part of the back side of the protrusion forming surface of the vertically long plate, and a hole is provided in the lower part of the vertically long plate, and one notch This curtain runner is characterized in that one protrusion fits into the curtain runner and is used as an integral part.

c. Problems to be Solved by the Invention As described above, runners used for curtain rails having an I-shaped longitudinal side are generally engaged from the side ends of the rails. Therefore, it is not easy to add the runner after installing the rail.
That is, if you find that there are not enough runners after installing an end cap on the side end of the rail or after attaching the rail to the wall using a wall bracket, remove the cap from the side end of the rail, or There was a problem in that the runner had to be engaged after the rail had been removed from the bracket.

Note that the runner described in the above-mentioned publication is completely different from the runner for the I-shaped vertical side curtain rail of the present invention, and is for a so-called square-shaped curtain rail, and has a different structure from the additional runner of the present invention. They are different.

The present invention is a runner for a curtain rail with an I-shaped longitudinal side, and although it has a simple configuration, it is possible to easily and quickly add runners by combining them from the front and back sides of the rail whenever necessary, even after the rail is installed. The purpose is to ensure that once they are combined and added to the rail, they will be combined reliably and will not fall off.

B. Structure of the invention a. Means for solving the problem The additional runner A of the curtain rail according to the invention has grooves for engaging rolling wheels on both sides, and
In a runner that is U-shaped when viewed from the side and is used for a curtain rail 1 having an I-shaped vertical side surface and having rail portions 2 and 2' on each side, the U-shaped runner is divided into an L-shaped member 6 and an inverted L-shaped member 7. The rolling wheels 3 and 4 are mounted on the shafts 10 and 1 inside the vertical plate portions 8 and 9 of both members 6 and 7, respectively.
A horizontal hole 13 parallel to the longitudinal direction of the rail 1 is provided in the horizontal plate portion 12 of one of the members 6 and 7.
A connecting piece 16 is formed on the horizontal plate portion 15 of the other member 7 and has a bifurcated shape that can be engaged with the horizontal hole 13 and has locking edges 17, 17 at the tip thereof for engagement with the inner end of the horizontal hole 13. It is made up of the following.

In the above configuration, the L-shaped member 6 and the inverted L-shaped member 7 have a U-shape when viewed from the side when combined, but the shape is made to be the same as that of the other normal runners 18. The reason why the connecting piece 16 is bifurcated is that when it is inserted into the horizontal hole 13, the interval between the two is narrowed, and after it is completely inserted, it expands elastically and the locking edges 17, 17 are inserted into the horizontal hole 13. This is to prevent it from being locked at the end and easily pulled out.

In addition, it is preferable that the materials other than the shafts 10, 11 of the rolling wheels 3, 4 and the hanging ring 5 are made of semi-hard synthetic resin. In the figure, 14, 14 is a locking enlarged part formed at the back end of the horizontal hole 13, 19 is a bracket, 20 is an end cap, 21 is a wall surface, and 22
is a wall bracket.

b. Effect The additional runner A of the present invention is used as follows.

After installing the end caps on the side ends of the curtain rail 1 or after attaching the rail 1 to the wall 21, for example with the wall brackets 22, it may be noticed that the number of conventional runners 18 engaged with the rail 1 is insufficient.

In that case, first one member, for example, the L-shaped member 6
on the front side of the rail 1, and the other member, for example, the inverted L-shaped member 7, on the rear side of the rail 1, and the rolling wheels 4,
3 at the rail portions 2, 2' on each side. Then, by aligning both members 6 and 7 with the rail 1 in between, it is sufficient to insert the connecting piece 16 of the other member 7 into the horizontal hole 13 of one member 6.

In this case, since the connecting piece 16 is bifurcated, it enters the horizontal hole 13 with a narrow interval, but once inserted, it expands elastically, and the locking edges 17 at the tip end in the horizontal hole 13.
3 or if enlarged locking portions 14, 14 are formed, it will be locked there and will not come out.

The additional runner A of the present invention integrated and attached to the rail 1 as described above performs the same function as the normal runner 18 already attached, and its shape remains the same. be.

C. Effects The additional runner according to the present invention has the following effects.

a Runners can be added easily and quickly even after installing the curtain rail. That is, in the past, when it became necessary to engage or add a runner after the rail was installed, troublesome work was required, such as removing the end cap or removing the rail from the bracket.

However, in the present invention, it is only necessary to insert the connecting piece of one of the L-shaped member and the inverted L-shaped member into the horizontal hole of the other from the front and back sides of the rail. As a result, both members come together and become similar to a normal U-shaped runner when viewed from the side. Therefore, with the additional runner of the present invention, anyone can easily and quickly add a runner to the rail even after the rail is installed.

b Once the runner is engaged with the rail, it will not accidentally separate or fall off. In other words, even if the runner is once connected and engaged with the rail, if the runner separates and falls off when a large external force is applied, such as when a curtain is pulled, the runner must be reattached to the rail. .

In contrast, the additional runner of the present invention has two
Since the fork-shaped elastic connecting piece expands after being inserted into the horizontal hole and the locking edge is locked, there is no risk of it separating or falling off even if an external force is applied inadvertently, so it can be used with confidence.
