Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an accordion type curtain.

Conventionally, the length of the curtain body of commercially available accordion-style curtains is fixed, and the length of the curtain body is fixed depending on the location.If the hem part touches the floor, the hem part of the curtain body may be cut off, or if there are many gaps, the length of the curtain body is fixed. This method has the disadvantage that the sewing thread at the hem of the curtain body must be removed, the folded portion must be extended, and the folded portion must be re-sewn or fixed with adhesive or the like.

This invention was devised in view of the above points, and the curtain runner of an accordion-style curtain is pivoted to the upper and lower horizontal protrusions of the metal frame body, which has a shape in which the upper horizontal protruding piece and the lower horizontal protruding piece protrude in the same direction. A hole is bored, and a headed shaft is inserted from above into the shaft hole of the lower horizontal protrusion, and is rotatably pivoted to the central connecting part of the parallel link forming the telescopic framework of the accordion curtain. A shaft rotatably held by a hanging rod, which rotatably supports a wheel for fitting the curtain rail at the upper end, is inserted from above into the shaft hole of the piece, and a locking protrusion is fitted and connected to the lower end of the shaft. At the same time, a plurality of pieces are stacked vertically at a position between the lower surface of the horizontal protrusion and the upper surface of the locking protrusion of the shaft, and are removably fitted and fixed to form a shape, thereby increasing or decreasing the number of pieces. To provide an accordion-type curtain in which the distance between the hem of the curtain body and the floor surface can be adjusted by changing the length of the curtain runner.

Hereinafter, embodiments of the present invention shown in the drawings will be described in detail.

Reference numeral 1 denotes a metal frame body of a curtain runner, which is formed by bending a metal plate having a cross section in which an upper horizontal protruding piece and a lower horizontal protruding piece protrude in the same direction, and an upper horizontal protruding piece 2a has side grooves at both ends. A circular shaft hole 4a in which holes 3a and 3b are continuously drilled.
is bored in the center, and a shaft hole 4b is bored in the lower horizontal protrusion.

Further, the metal frame body 1 has a cover 5 molded from an elastic hard synthetic resin such as polyethylene, which is inserted into grooves 6a and 6b provided on the inside of the cover 5 at the outer edge of the metal frame body 1. av7b is fitted and installed, and shaft holes 9a and 9b having the same shape as the horizontal projections 2a and 2b of the metal frame main body 1 are formed in communication with the upper surface 8a and lower surface 8b of the cover 5, respectively.

Reference numeral 10 denotes a shaft for fitting and suspending the metal frame main body 1 on the curtain rail 11, and is a headed shaft that presses both sides of the lower part from the center to form flat parts 12a and 12b. A hanging rod 14 rotatably supporting a wheel 13 for fitting the curtain rail 11 is rotatably held, and the hanging rod 14 is inserted into the shaft holes 4a, 9a by inserting the flat portions 12a, 12b into the side grooves 3 of the shaft hole.
A and 3b are inserted from above, and then a washer 15 is inserted from the lower end, and an E-ring 17 is fitted into the groove 16 formed in several stages at the end of the shaft for coupling.

Reference numeral 18 denotes a curtain body 19a on the front and rear sides of the metal frame main body 1.

19b is a headed shaft for engaging the central connecting portion 21 of the extendable parallel link 20, and the shaft hole 4b
, 9b from above, and further into the central connecting portion 21 of the parallel link 20 from above, the E IJ song 3 is fitted into the groove 22 carved in the lower end of the shaft 18 and hung freely for rotation. It is meant to be held at the bottom.

Reference numeral 24 denotes a piece molded from an elastic hard synthetic resin such as polypropylene or polyethylene, and has a convex portion 26 projecting from one side with a small hole 25 vertically bored in the center, and a piece main body 27 having A through hole 2 having the same shape as the central cross section of the shaft 10
8, and cut and widen the opposite side of the protrusion 26 to continuously drill a vertical groove 29, and connect the piece 24 to the lower surface of the upper horizontal protrusion 2a of the metal frame main body 1. The two pieces are vertically stacked and fitted to the upper surface of the washer 15 which is conventionally inserted into the shaft 10.

Furthermore, 30a and 30b are L-shaped protrusions molded in series with the cover 5, which fit into the convex portion 26 of the piece 24 to prevent the piece 24 from falling off.

Since the present invention is constructed as described above, by increasing or decreasing the number of pieces, the length of the curtain runner can be changed, and the distance between the hem of the curtain and the floor surface of the accordion-style curtain suspended from the curtain runner can be changed. can be easily and accurately adjusted to an appropriate distance, and the piece can be attached and detached extremely easily by fitting it into a position between the plate surface of the upper horizontal protrusion and the upper surface of the locking plate. Furthermore, by fitting the removed piece to the shaft exposed on the soil covering surface as shown in the figure, the accordion-style curtain can be stored without fear of loss until it is hung somewhere else. It has the following effects.
