Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention is, for example, attached to an end of an outer curtain rail (hereinafter referred to as a rail) in a double curtain, and the rail is made small together with a guide groove in which the runner travels. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain rail corner joint that can be easily formed into a curved shape.

(B) Conventional Technique The above-mentioned double curtain is conventionally one in which two linear rails are simply arranged in parallel, and there are mainly the following three disadvantages.

First, the end of the rail is visible, which impairs its design value. The end of the rail may conventionally have various accessories attached to it, but it does not match the room or curtain. In some cases, it did not solve the problem.

Second, the rails are mounted so that they are passed by multiple brackets with the wall as the base end, but in the case of a double curtain, the load on the base end of the bracket is larger than that of a typical single curtain, which damages the wall. There were many things.

Thirdly, especially when the outer rail curtain is opened, the laterally contracted curtain is located at both ends of the outer rail, that is, on the indoor side, and not only occupies a place, but also when it is stopped with a belt, it is a design. No value is added to the above, and moreover, the burden on the bracket is increased due to the above-mentioned facts.

Therefore, in order to solve the above-mentioned problems, a corner joint which is slightly curved as described above is desired. In other words, if you use a corner joint at the end of the rail,
The first problem was solved by hiding the end of the rail, and the second problem was solved by attaching the curved ends of the outer rail to the wall like brackets.
Furthermore, the third problem can be solved by pushing the curtain of the outer rail toward the inner rail.

Therefore, when manufacturing a corner joint having a small curvature as described above, it is conceivable to bend the rail by applying a force from the outside during or after the formation of the linear rail. This manufacturing method is performed in the case of a large curved rail, and in fact, the curved rail manufactured in this way is used as a rail used for a curtain surrounding the bed of a hospital, so that it can be attached above the bed. It is used for many things.

(C) Problems to be solved by the invention However, in the case of the above-described manufacturing, although it is possible to bend to a certain extent, if the bend is made smaller than a certain amount, the groove shape of the inner guide groove is crushed. However, the runner had to be processed in a separate process again so that the runner could smoothly run, and thus the degree of curvature was naturally limited.

Further, even if an attempt is made to collectively mold the small curved corner joint as described above with a mold, the core portion of the mold for forming the guide groove cannot be removed after the formation, so that the mold cannot be formed.

The present invention has been made in view of the above problems, and an object thereof is to provide a curtain rail corner joint that has a guide groove that is slightly curved and can be formed easily and at low cost.

(D) Means for Solving the Problems The present invention has a corner joint for a curtain rail which has connecting portions for connecting the curtain rails at both ends and has a curved guide groove on the lower surface for the runner to travel. While the guide groove is formed to be slightly curved, the corner joint is divided and formed so that the outer curved outer member and the inner curved inner member can be connected to each other with the guide groove as a boundary. A guide strip that locks the other of the above-mentioned members is formed on one side of the L-shaped one of the curved inner members, and at least one end of each of the above-mentioned members is formed. It is a corner joint of a curtain rail provided with holding means for holding the ends of the connected curtain rails.

(E) Action The corner joint of the curtain rail of the present invention is an integrated curved guide groove in which the curved outer member and the curved inner member that form the curved guide groove are locked and coupled to each other through the guide strip. To form. At the time of use, the curtain rails are connected to the connecting portions at both ends so as to sandwich the curved inner member, and this connecting state is firmly held by the holding means.

(F) Advantageous effect of the invention As described above, according to the invention, the curved guide groove, which cannot be formed by the mold in the related art, is divided and formed so that the corner joint having the small curved guide groove can be formed by the mold. It became easier to manufacture. As a result, by using this corner joint, it is possible to improve the design feeling in the case of a double curtain, firmly fix the wall without damaging it, and treat the opened curtain material with a good appearance.

Further, since the outer curved member and the inner curved member are engaged with each other through the guide strip, the connection can be easily performed while maintaining a predetermined relationship.

Further, since holding means for holding the connected curtain rails is provided at both ends of at least one of the curved outer member and the curved inner member, the coupling by the above-described guide strip is performed. The condition can be surely achieved by being sandwiched between the curtain rails.

Moreover, since the curtain rail is firmly held, it does not come off unexpectedly, and it looks as if it were a single curtain rail. Therefore, even if the guide groove has a small curvature, the runner can be expected to travel smoothly.

(G) Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.
