Description

[Detailed Description of the Invention] Technical Field This invention relates to a curtain rail joint for connecting a plurality of curtain rails so that their mutually opposing end surfaces match.

Prior Art Generally, as shown in FIGS. 1 and 2, a curtain rail 1 is attached to a ceiling 2 or the like at its upper part, and the curtain rail 1 is attached to a hollow part 3 of the curtain rail 1.
A plurality of runners 6 fixed to the curtain body 5 at predetermined intervals can be rotatably accommodated through slits 4 at the lower part of the curtain body. Also,
A pair of grooves 7 are formed on both sides of the slit 4 and extend in parallel in the longitudinal direction.

When connecting a plurality of curtain rails 1a, 1b such that their mutually opposing end surfaces 8a, 8b match, one curtain rail 1a,
After inserting the entire small diameter wire joint 9 into the pair of grooves 7, the end surface 8b of the other curtain rail 1b is inserted into the end surface 8 of the one curtain rail 1a.
a, and then move the joint 9 to both curtain rails 1a, 1b until the center of the joint 9 almost matches the connecting part of both curtain rails 1a, 1b.
Slide the joint 9 along the groove 7 of 1b.
The two curtain rails 1a and 1b are connected by the frictional force between the circumferential surface of the curtain rail and the inner wall of the groove portion 7.

However, in this conventional joint 9, a part of the circumferential surface of the joint 9 is exposed from the groove 7 at the bottom of the curtain rail 1, which not only makes the appearance of the curtain rail 1 and the curtain as a whole unsightly, but also makes the installation position difficult. is set below the rolling surface 3a of the runner 6, the vibration caused by the rolling of the runner 6 moves the joint 9 toward one of the curtain rails 1, and both curtain rails 1a, 1b The problem was that the connecting surfaces of the connectors tend to shift in both the vertical and horizontal directions, and furthermore, it takes time and effort to assemble them.

Purpose This invention was made to eliminate the above-mentioned defects, and its purpose is to easily and reliably connect multiple curtain rails so that the mutually opposing end surfaces of the multiple curtain rails match. To provide a novel joint for a curtain rail which is simple in structure, can be completely housed in the curtain rail during use, does not spoil the appearance of the curtain rail, and has a simple structure.

Example Next, the first example that embodies this idea will be described in the third example.
4 and 6, as shown in FIGS. 3 and 4, a hollow part 12 is formed in the curtain rail 10, and a hollow part 12 is formed in the lower center of the curtain rail 10, and the curtain rail 10 is continuous with the hollow part 12. A slit 13 is formed extending in the longitudinal direction. Curtain body 1 placed below this slit 13
A plurality of runners 15 are fixed to the upper edge of 4 at predetermined intervals. And this runner 1
The rolling wheels 15a of No. 5 are housed in the hollow part 12 of the curtain rail 10 through the slit 13, and can roll on the rolling surfaces 16 on both sides of the slit 13. Accordingly, the curtain body 14 can be opened and closed.

A protruding portion 17 is formed in the upper center of the curtain rail 10 in the longitudinal direction, and a plurality of attachment holes 17a communicating with the hollow portion 12 are formed on the upper surface at predetermined intervals. A pair of grooves 18 are formed in the upper part of the curtain rail 10, sandwiching the mounting hole 17a, and extending in parallel in the longitudinal direction. Further, a pair of hook-shaped groove forming portions 19 are provided on both upper side edges of the curtain rail 10 and protrude inwardly, forming a groove portion 18 with both side walls of the protrusion portion 17. Note that the tip of the groove forming part 19 is connected to each groove part 18.
It extends toward the center of the curtain rail 10 so as to cover approximately 1/3 of the curtain rail 10. Further, the upper surface of the groove forming portion 19 and the upper surface of the protruding portion 17 are on the same plane.

Then, a plurality of screws 2 are inserted through the mounting hole 17.
0, when the curtain rail 10 is attached to a ceiling 21 or the like, the upper surface of the protruding portion 17 and the upper surface of the groove forming portion 19 come into close contact with the ceiling 21, and the groove portion 18 is closed.

Next, the structure and mounting structure of the joint 22 for connecting a plurality of curtain rails 10 will be explained in detail. As shown in FIGS. 3, 4, and 6, the joint 22 is formed by bending a wire rod with a small diameter. The wave portions 23a of the wavy base end portion 23 are located on the same plane, and the wave height H is slightly larger than the width of the groove portion 18 of the curtain rail 11.

The distal end portion 24 integrally formed with the wavy proximal end portion 23 is in its natural state.
It is designed to protrude beyond the straight line S1 that is in contact with the apex of each wave portion 23a.

Therefore, as shown in FIG. 3, the joint 2 is
A part of the tip 24 of 2 is the protrusion 17 of both grooves 18.
When the wavy base ends 23 of the pair of joints 22 are inserted so that they are located on the extension line of the side inner walls, the wavy base ends 23 resist their own elasticity and narrow the wave height H. It is clamped and pressed and fixed to the inner walls of both grooves 18 by the reaction force. In addition, in this state, the tips 24 of the pair of joints 22 are connected to the cross section 1 of one curtain rail 10a.
The tips 24 of both joints 22 protrude from 1a.
The distance M between the protrusions 17 is set to be slightly smaller than the distance L between the side walls of the protrusion 17.

Next, as shown in FIG. 3, the end surface 11b of the other curtain rail 10b and the one curtain rail 1
When the tips 24 of each joint 22 are accommodated in both grooves 18 of the other curtain rail 10b so that the end surfaces 11a of the joints 22 face each other and match, the distance M between the tips 24 of both joints 22 is determined by its own elasticity. The reaction force applies a pressing force to the inner wall of both grooves 18 on the side of protrusion 17, and both curtain rails 10a, 10b are opened in a state where mutually opposing end surfaces 11a, 11b are aligned. Curtain rails 10a and 10b can be easily and reliably connected.

In addition, with both curtain rails 10a and 10b connected, screws 20 inserted into the mounting holes 17 are used to attach both curtain rails 10a and 10b to the ceiling 21.
When installed in the groove 18, the pair of joints 22 accommodated in the groove 18 are not only completely covered by the ceiling 21, but also prevent the joints 22 from moving within the groove 18 even if the runner 6 is frequently rolled. There is no. Therefore, both curtain rails 10a, 1
The runner 6 can be rolled smoothly without spoiling the aesthetic appearance of the curtain rail 0b and without causing any vertical or horizontal displacement in the connecting surface of the curtain rails 10a, 10b.

Another Embodiment Next, a second embodiment of this invention will be described with reference to FIGS. Direct S1 in contact with the vertex of part 23a
It differs from the first embodiment in that it is formed on a straight line S2 that forms a predetermined angle θ with the straight line S2, and the tip 24 intersects the straight line S1. Therefore, during use, a portion of the tip 24 applies a pressing force to the inner wall of the pair of grooves 18 of the curtain rail 10 on the protrusion 17 side.

Next, a third embodiment of this invention will be explained according to FIGS. 8a to 8e. In this embodiment, the joint 22
One arcuate portion 24a is formed on the outer end portion 24 on the same plane as the wavy base end portion 23 of the wavy base portion 23, and the approximate center of this arcuate portion 24a protrudes from the straight line S1 in the natural state. Each embodiment is different. Therefore, when using it, the arcuate portion 2
Approximately the center of 4a applies a pressing force to the inner wall of the pair of grooves 18 of the curtain rail 10 on the protrusion 17 side.

Next, a fourth embodiment of this invention will be explained with reference to FIGS. 9a to 9e. In this embodiment, the joint 22
A plurality of arcuate portions 24a are formed on the distal end portion 24 on the same plane as the wavy base portion 23 of the wavy base portion 23, and a portion of the arcuate portions 24a protrudes from the straight line S1 in the natural state. It is different from the example. Therefore, when in use, the arcuate portion 24a
applies a pressing force to the inner wall of the pair of grooves 18 of the curtain rail 10 on the protrusion 17 side.

Note that this invention is not limited to the above embodiments, and for example, the tip 2 of the joint 22
4 to the protrusion 17 of the groove 18 of the curtain rail 10
Instead of inserting so as to apply a pressing force to the side inner wall, it is also possible to insert and fit the tip 24 of the joint 22 so as to apply a pressing force to the inner wall of the groove 18 on the outside of the curtain rail, Furthermore, in that case, as shown in FIG. 5, a protrusion 31 extending in the longitudinal direction is formed on the upper part, and a pair of grooves 32 extending in parallel in the same direction are formed on both sides of the protrusion 31. It is also possible to connect a plurality of curtain rails 30 configured such that the upper surface of the protruding portion 31 and the upper edge of the outer wall 33 of each groove portion 32 are located on the same plane.

Effects As detailed above, in this invention, a joint made of wire is bent so that the wave height is wider than the width of the groove in its natural state, and the joint is inserted into a pair of grooves on one curtain rail. The wavy base end portion protrudes from the end face of one curtain rail when the wavy base end portion is inserted, and is inserted into a pair of grooves of the other curtain rail, and when the wavy base end portion is inserted into the other curtain rail, the wavy base end portion protrudes from the end face of one curtain rail. Since the distal end section is provided to apply a pressing force to the inner wall of the pair of grooves, by inserting the wavy base end section into the groove section of one curtain rail against its own elasticity, the distal end section can be inserted into the groove section of one curtain rail. With the joint firmly protruding from the curtain rail, the joint can be firmly attached to one curtain rail at its wavy base end, and when connected to the other curtain rail in this attached state, the joint can The rail does not collide with the tip of the curtain rail and the tip of the curtain rail does not sink into one of the curtain rails, and with the opposing end surfaces of both curtain rails aligned, the pressing force of the tip The other curtain rail can be reliably connected to one curtain rail.

Moreover, when this joint is used, it is entirely accommodated within the curtain rail, so that the appearance of the curtain rail is not spoiled, and there is no risk of the joint moving due to rolling of the runner, which is an excellent effect.
