Description

The present invention relates to a curtain runner used in a curtain rail having a gate-shaped cross section.

In a curtain runner used in a curtain rail having a gate-shaped cross section, the first conventional technique disclosed in Patent Document 1 is to make the front T-shape and insert the legs into the grooves of the tube-shaped curtain rail, so that the curtain runners are connected to both the left and right sides of the head. In a synthetic resin curtain runner in which a part of the runner straddles the rails on both sides of the groove, the front and back width of the head is equal to or smaller than the width of the groove, and the legs At least one of the front and rear sides of the leg is provided with a retractable protrusion biased in the protruding direction by a spring to prevent the leg from rotating within the groove under normal fitting conditions. (Scope of claims for utility model registration) This curtain runner also has stoppers on both the left and right sides of the legs to prevent it from lifting up.

In addition, as a second conventional technique for curtain runners, in curtain runners that hang heavy curtains, the main body portion of the liner consisting of the head and legs is required to be strong, so there is a curtain runner made of metal.

Publication No. 58-22629

In the first conventional technology, the entire liner is made of synthetic resin, so even if the legs come into contact with a curtain rail made of metal (including light metals such as aluminum alloy), there will be no sliding noise or collision noise. However, if the legs of the liner are made of metal (including light metals such as aluminum alloy) as in the second prior art, the legs may be made of metal. When the curtain rail comes in contact with the curtain rail, a sliding noise may be produced, and it becomes difficult to form protrusions, stoppers, etc.

An object of the present invention is to provide a curtain runner that can solve the problems of the prior art.
SUMMARY OF THE INVENTION An object of the present invention is to provide a curtain runner in which the center portion and leg portions of the runner shaft can be covered with a cover body made of synthetic resin separately from the runner body.

Embodiments of the present invention will be described below based on the drawings.
1 to 12 show embodiments of a curtain runner 1 used in a curtain rail L having a gate-shaped cross section. The curtain runner 1 has a runner body H made of metal and a cover body K made of synthetic resin. It is constructed by covering.
The runner main body H includes an upper runner shaft 3 arranged horizontally, a moving section 4 provided at both ends of the runner shaft 3 for moving the rail portion La of the curtain rail L, and a runner body H that hangs down from the center of the runner shaft 3. It is composed of a leg part 5 that passes through the rail groove Lb of the curtain rail L, and a hanging fitting 6 provided at the lower part of this leg part 5.

The runner shaft 3 has a large-diameter portion 3a with a large diameter at the center in the axial direction, and its upper and lower portions are removed horizontally to form an oval shape when viewed from the front, as shown in FIG. A vertical through hole 3d perpendicular to the runner axis S is formed in the center of the large diameter portion 3a. Both ends of the runner shaft 3 have small diameter portions 3b having a smaller diameter than the large diameter portion 3a.
The leg portion 5 is formed of a bar separate from the runner shaft 3, and is vertically penetrated through a through hole 3d at the center of the large diameter portion 3a, and is expanded to a large diameter by caulking the top portion 5a to form the through hole 3d. held to prevent it from falling. The runner shaft 3 and the leg portion 5 form a substantially T-shape in side view, and the leg portion 5 is rotatable about the vertical axis with respect to the runner shaft 3.

The moving portion 4 is formed by fitting bearings into small diameter portions 3b at both ends of the runner shaft 3. The moving part 4 becomes a rotating wheel by using a bearing, but the wheel may be fitted into the small diameter part 3b so as to be freely rotatable, or it may be a non-rotating slider.
The hanging fitting 6 is formed by fixing (welding) a ring 15 to the lower end of the leg portion 5.
In addition to the curtain runner 1 that uses the rings 15 as the hanging fittings 6, there are also curtain runners that use snaps. The curtain runner 21 of the first modification shown in FIGS. 13 to 15 uses snaps 18, and a hanging member 17 having a shaft pin 16 is fixed to the lower end of the leg portion 5 made of bar material. It is constructed by engaging a snap 18 with a shaft pin 16.

In FIGS. 1 to 15, the cover body K that covers the runner body H includes a head fitting part 8 that covers the large diameter part 3a at the center of the runner shaft 3, and a head fitting part 8 that hangs down from the lower part of this head fitting part 8 and extends to the legs. A leg fitting part 9 covering the part 5 is integrally molded with synthetic resin, and a slit 10 is formed from the lower part of the head fitting part 8 to the leg fitting part 9 to separate it back and forth in the longitudinal direction of the curtain rail L. ing.
The head fitting part 8 has a shape that avoids the top part 5a of the leg part 5 and tightly fits on the outer periphery of the oval-shaped large diameter part 3a. At the same time, the top portion 5a of the leg portion 5 is prevented from rising from the large diameter portion 3a. That is, the head fitting portion 8 can restrict upward movement of the leg portion 5 made of bar material with respect to the runner shaft 3.

At the front and rear portions of the outer periphery of the head-fitting portion 8, buffer portions 12 are provided with front and rear projecting shapes. The buffer section 12 has a bifurcated shape with two levels, upper and lower, and protrudes forward and backward from the outer periphery of the moving section 4, so that adjacent curtain runners 1 within the curtain rail L are likely to come into contact with each other, as shown by the imaginary line in FIG. Even if the movable parts 4 contact each other or collide with each other, contact and collision between the movable parts 4 can be avoided, and contact impact between the buffer parts 12 can be buffered.

Note that if the insertion direction of the curtain runner 1 into the curtain rail L is always constant, the buffer portion 12 may be provided only on one of the front and rear sides of the outer peripheral surface of the head fitting portion 8.
The leg fitting part 9 is narrower than the width of the head fitting part 8, but wider than the diameter of the leg part 5, and by covering the leg part 5, when passing through the rail groove Lb of the curtain rail L, the rail Metal contact between part La and leg part 5 is avoided.

Since a slit 10 is formed from the lower part of the head fitting part 8 to the leg fitting part 9 to separate it back and forth in the longitudinal direction of the curtain rail L, the cross-sectional shape of the leg fitting part 9 has two circular arcs facing each other. shape, and can be elastically deformed from the lower part of the head fitting part 8 to the leg fitting part 9 so as to move away from each other back and forth.
A projecting portion 11 is formed at the lower part of the leg fitting portion 9. The projecting portion 11 projects outward from the leg fitting portion 9 to the left and right and overlaps the rail portion La of the curtain rail L. The projecting portion 11 has a slit 10 formed in the center, and as shown in FIGS. 7 and 12, it is formed into a rectangular shape (square, rectangle, etc.) in plan view with flat surfaces on the left and right sides.

Since the projecting portion 11 has a projecting shape that overlaps the rail portion La, the curtain runner 1 floats within the curtain rail L, and the ring 15 rotates so as to enter into the rail groove Lb. In addition, since the left and right sides are flat surfaces and the directionality of the curtain runner 1 can be recognized by pinching them with fingers, it is possible to check the directionality of the curtain runner 1 when inserting the curtain runner 1 into the curtain rail L. It can be used to make it appropriate.

The cover body K is made of synthetic resin, and has a slit 10 that separates the curtain rail L from the lower part of the head fitting part 8 to the leg fitting part 9 in the longitudinal direction of the curtain rail L. It can be enlarged and fitted from the top of the runner body H to cover it. Further, before the moving part 4 is attached to the runner shaft 3, the cover body K can be fitted to the runner shaft 3 and the leg part 5 from the axial direction of the runner shaft 3.

As the synthetic resin forming the cover body K, in addition to thermoplastic resins such as polyacetal, nylon, ABC, polypropylene, etc., thermosetting resins such as silicone resin can also be used.
16 to 18 show a second modification of the curtain runner 31, in which a shackle is applied as the hanging fitting 6, and a U-shaped fitting 32 is welded to the lower end of the leg portion 5 made of bar material. A threaded rod 33 is screwed onto both ends of the letter-shaped metal fitting 32 so as to close the opening between both ends.

Similarly to the embodiment described above, the curtain runner 31 of this second modification also has a runner main body H made of metal covered with a cover body K made of synthetic resin.
In the embodiment described above, the curtain runner 1 includes a runner shaft 3, a moving section 4 provided at both ends of the runner shaft 3 that moves the rail section La of the curtain rail L, and a moving section 4 that moves from the center of the runner shaft 3.
