For this reason, a connecting member such as a magnet is attached to the leading runner to attract both leading runners to each other. However, the mounting structure for this connecting member has been complicated in order to prevent the connecting member from easily falling off the runner during use. As a result, the work of attaching the connecting member to the runner has become extremely troublesome.

Purpose of the invention This invention was made in order to solve the above-mentioned problems.The purpose of this invention is to make it possible to assemble the connecting member very easily, and to prevent the connecting member from falling off the leading runner during use. To provide lead runners for rails.

Structure of the invention In this invention, in a leading runner for a curtain rail, the runner main body is opened on the traveling direction side to provide a storage chamber, and a flexible locking part is formed inside the storage chamber, while the attraction part is attached to a magnet. A metal frame bent toward the front end side and having an engaging portion formed on the side surface is inserted into the storage chamber through the opening thereof with a magnet sandwiched therebetween, and the engaging portion is connected to the flexible locking portion. It is designed to be irremovably engaged.

Embodiment An embodiment embodying this invention will be described below with reference to the drawings.

FIG. 1 shows a pair of leading runners 2 made of synthetic resin on the left and right that are fitted in a curtain rail 1 so that they can run, and a number of intermediate runners (not shown) are fitted behind each of them. There is. Reference numeral 4 denotes a pair of left and right arms extending upward from the upper side of the runner main body 3, to which a pair of front and rear pulleys 5 are rotatably attached, as shown in FIGS. 3 to 7, respectively. As shown in FIGS. 1 and 2, this pulley 5 rolls on the rail portion 1a of the curtain rail 1, so that the runner body 3 runs along the curtain rail 1 in a suspended state. do. 6 is a transparent structure 3 provided on the lower side of the runner body 3.
A hook attached to a curtain (not shown) is hung in a desired hanging hole 6.

Reference numeral 7 denotes a storage chamber formed by bulging both the front and rear sides of the runner main body 3 at the upper position of the hanging hole 6 as shown in FIG. A shaped opening 7a is formed, and a window hole 7b is formed through the rear side wall of the storage chamber 7. Reference numeral 8 denotes a flexible locking arm extending from the central position of the front edge of the window hole 7b to the rear of the storage chamber 7,
As shown in FIG. 9, a locking protrusion 9 whose inner surface is tapered is provided on the inside of its tip, and its rear end surface serves as an engagement surface 9a.

Next, a description will be given of a connecting member that is installed in the storage chamber 7 formed in the runner body 3 and connects the pair of left and right leading runners 2 to each other. In this embodiment, the leading runner 2 on the right side in FIG.
Since the leading runner 2 on the left side and the leading runner 2 have different connecting members, the connecting member attached to the right runner 2 will be explained first.

In FIG. 11, reference numeral 11 is a magnet, and a plate-shaped metal frame 12 is attracted to both sides of the magnet by the magnetic force of the magnet 11. The tip of the metal frame 12 is bent to form a suction portion 12a over its entire surface. 1
Reference numeral 3 denotes an engagement hole transparently provided in the rear side of the metal frame 12, into which a locking projection 9 provided in the storage chamber 7 is fitted.

Then, the magnet 11 and metal frame 1 shown in FIG.
When the metal frame 12 is inserted into the housing chamber 7 of the leading runner 2 from the opening 7a with the metal frame 12 facing backward, the rear end of the metal frame 12 slides against the tapered surface of the locking protrusion 9 while pushing the locking protrusion 9 and the locking arm 8 outward. push it out. Therefore, the magnet 11 and the metal frame 12 are smoothly inserted into the storage chamber 7. The magnet 11 and the metal frame 12 are inserted further back, and the engagement hole 13 of the metal frame 12 is inserted into the storage chamber 7.
When the locking arm 8 reaches the window hole 7b, the locking arm 8 which has been pushed outward returns to its original position by its own elastic force, so that the locking protrusion 9 fits into the engagement hole 13 of the metal frame 12. Then, the engagement surface 9a of the engagement projection 9 engages with the rear end edge of the engagement hole 13, and the magnet 11 and metal frame 12 are installed in the storage chamber 7 in a manner that cannot be removed.

Next, the connecting member attached to the left leading runner 2 in FIG. 1 will be explained.

In FIG. 15, reference numeral 14 denotes a connecting fitting having both side portions 14a bent upward;
An engagement hole 15 is transparently provided on the rear side of 4a. Reference numeral 16 denotes a suction plate formed by bending the front end of the connecting fitting 14 upward in an L-shape, and the entire surface thereof is attached to the suction surface 1.
It is set as 6a.

When this connecting fitting 14 is inserted backward into the accommodation chamber 7 of the leading runner 2 through the opening 7a, the rear end of the side portion 14a of the connecting fitting 14 slides against the tapered surface of the locking protrusion 9 and locks the same. Push out the protrusion 9 and locking arm 8 to the outside. Therefore, the connecting fitting 14 is smoothly inserted into the storage chamber 7. When the connecting fitting 14 is inserted further into the back and the engagement hole 15 provided in the side part 14a reaches the window hole 7b of the storage chamber 7, the locking arm 8 that has been pushed outward is removed.
Since the locking projection 9 returns to its original position by its own elastic force, the locking projection 9 fits into the engagement hole 15. Then, the engagement surface 9a of the engagement protrusion 9 engages with the rear edge of the engagement hole 15, and the connecting fitting 14 is installed in the storage chamber 7 in a manner that cannot be removed.

In this way, both leading runners are curtain rail 1
When they face each other in close proximity to each other, the magnetic force of the magnet 11 attached to the right-hand leading runner 2 causes the attraction portion 12a of the metal frame 12 and the attraction plate 16 of the connecting fitting 14 attached to the other leading runner 2 to move together. each other first
As shown by the dashed line in the figure, the leading runners 2 are attracted to each other and are connected to each other.

In this way, in this embodiment, the magnet 11 and the metal frame 1
2 into the accommodation chamber 7, the locking protrusions 9 are pushed outward and when these connecting parts are completely accommodated, they return by their own elastic force and lock into the respective engagement holes 1.
3 and 15, it is very easy to assemble and can be attached reliably. Furthermore, even if both runners 2 are separated against the magnetic force of the magnet 11, the magnet 11 and the metal frame 12 will not fall off because they are each locked by the locking projections 9.

Note that this invention is not limited to the embodiment described above; for example, in the embodiment described above, two locking protrusions 9 were provided in the storage chamber 7, but it may be implemented with one locking protrusion 9, or as shown in FIG. As shown in the figure, the connecting fitting 14 attached to the accommodation chamber 7 of the leading runner 2 may be attached to the accommodation chamber upside down, or other modifications may be made as appropriate without departing from the spirit of this invention.

Effects As detailed above, this invention is a leading runner that is fitted to a curtain rail and runs inside the rail.The runner main body is opened on the traveling direction side to provide a storage chamber, and the inside of the storage chamber is opened. A flexible locking part is formed in the metal frame, and the adsorption part is bent toward the front end surface of the magnet, and a metal frame with an engaging part formed on the side surface is inserted into the storage chamber with the magnet sandwiched in its opening. Assembling can be performed very easily by inserting the engaging part from the top and causing the engaging part to be irremovably engaged with the flexible locking part. At this time, the magnet can be made unreleasable from the lead runner by simply sandwiching the magnet between the metal frames, and there is no need to drill a locking hole or groove in the magnet body to make the magnet unreleasable. Not only does the mechanical strength of the magnet not deteriorate, but the processing cost of the magnet can be reduced. Furthermore, the connecting member does not fall off from the leading runner during use, making it a practical idea as a leading runner for curtain rails.
