Description

The present invention relates to a curtain support structure , and more particularly to a curtain support structure that can hold beautiful pleats on a curtain when the curtain support structure is attached to a curtain and suspended from a curtain rail.

  In order to attach the curtain to an opening such as a window, a vertical insertion rod for attaching to the curtain and a lower portion of the runner are connected to the insertion rod in the lower portion and extend in the vertical direction in parallel with the insertion rod. A curtain hanger has been used that includes a main rod provided with a hook body for hanging on a hook.

  In this curtain hanging tool, one wire is bent and the insertion rod, the main rod, and the hook portion are integrally formed, and it is the simplest and cheapest. A curtain hanger of shape and size is required.

  There is also a case in which the insertion rod, the main rod, and the hook body are integrally formed of a polymer resin. Since this curtain hanger can be manufactured by casting a molten resin in the mold, it is more suitable for mass production than a wire bending mold, but, similar to a wire curtain hanger, there are various types depending on the installation position of the curtain. A curtain hanger of the shape and size is required.

  On the other hand, the insertion rod and the main rod are integrally formed of a polymer resin, and a rack portion is formed on the main rod, and a polymer having an engagement piece that elastically engages with the rack portion of the main rod. By attaching a hook made of resin and engaging the hook's engagement piece with the main rack, the hook can move in a ratchet manner from the top to the bottom. There is what I did.

By the way, in the above-mentioned curtain suspender in which the hook body is movably attached to the integral type or main body of the polymer resin, there are the following problems due to the elastic deformation of the polymer resin.
(1) Since the leading end of the insertion rod bends to the left and right with respect to the main rod, if the leading end of the insertion rod inserted into the fold tack portion formed on the curtain is bent to the left and right, the tack portion tilts and the curtain Beautiful folds can be damaged.
(2) Since the entire insertion rod is bent to the left and right with respect to the main rod, if the entire insertion rod inserted into the fold tack portion formed on the curtain is bent to the left and right, the tack portion will be biased to either the left or right. The left and right may become uneven and the folds of beautiful curtains may be damaged.

  Therefore, as in the curtain hanger 20 shown in FIG. 7, the main rod 21 and the insertion rod 22 are integrally formed of a polymer resin, and the hook body 23 is movably attached to the main rod 21. 22 is provided with a penetrating pin 22a extending toward the main rod 21, and the penetrating pin 22a is passed through the curtain to prevent the distal end portion of the insertion rod 22 from bending to the left or right, or to the left and right of the entire insertion rod. There are some which prevent bending (for example, refer to patent documents 1 and 2).

Japanese Patent No. 2588160 ([0013], FIG. 3) JP-A-8-256901 ([0009], FIG. 3)

  However, according to the curtain hanger 20 provided with the penetrating pin 22a, by inserting the penetrating pin 22a into the seam of the curtain, the distal end portion of the insertion rod 22 is bent to the left and right to some extent, Although bending to the left and right can be prevented, there has been a problem that bending of the insertion rod 22 cannot be completely prevented.

  Accordingly, an object of the present invention is to provide a curtain hanger that can more reliably prevent the distal end of the insertion rod from bending to the left and right and the entire insertion rod from bending to the left and right to hold the beautiful folds of the curtain. To do.

The curtain support structure of the present invention supports a curtain by folding the upper end of the curtain and sewing the seams at both ends of the tuck part formed in a single or a plurality of longitudinal directions for fold formation. In the curtain support structure, a vertical insertion rod for attaching to the curtain, and a hook body that is continuous with the insertion rod in the lower portion, extends in the vertical direction in parallel with the insertion rod, and is hooked on the hanging ring of the runner A bending portion provided at a tip end portion of the insertion rod, and the bending portion is formed on the inner side with respect to a hole between stitches of the stitched seam of the curtain. The sewing part of the tacking part of the curtain is brought into contact with the connecting part of the main rod and the insertion rod .

  Here, the term “hole provided in the curtain” is obtained by folding the upper end of the curtain and stitching the joints at both ends of the tuck portion formed in a single or a plurality of longitudinal directions for pleat formation. In the gap between the seams, the bent portion of the insertion rod penetrates the gap between the seams from the inside to the outside.

  The longitudinal cross-sectional shape of the connecting portion between the main rod and the insertion rod may be formed into an irregular cross-sectional shape in which the upper side gradually becomes thin (Claim 2).

Further, the longitudinal cross-sectional shape of the connecting portion between the main rod and the insertion rod may be formed in a teardrop shape in which the upper side gradually becomes thin (Claim 3).

  Moreover, it is good to form the cross-sectional shape of the said insertion rod in the shape of a rugby ball | bowl from which the main rod side and the non-main rod side become thin-walled gradually. (Claim 4).

  Moreover, it is good to project and form the blade | wing part parallel to a curtain surface on the both right and left sides of the said main fence (Claim 5).

Also, a rack portion is formed on the main rod, and the hook body is formed separately from the main rod and has an engagement piece that elastically engages with the rack portion of the main rod and moves to the main rod. It is preferable that an anti-sway portion that clamps the main rod from both sides is provided at a position that is freely mounted and is separated from the engaging piece of the hook body.
Moreover, it is preferable to form the tip of the bent portion of the insertion rod into a hemispherical shape.

The curtain hanging tool used in the present invention has a vertical insertion rod for attaching to the curtain, a lower portion that is continuous with the insertion rod, extends in the vertical direction in parallel with the insertion rod, and is hung on the hanging ring of the runner. And a main board provided with a hook body . Since the bent portion that penetrates the hole provided in the curtain from the inside to the outside is provided at the tip of the insertion rod, the insertion rod is simply inserted into the tack portion of the curtain, or the penetration pin is penetrated through the curtain. In comparison, the tip of the insertion rod or the entire insertion rod can be bent left and right by penetrating a hole provided in the curtain from the inside to the outside and further extending the bending portion along the curtain. It is prevented, and the tack part for pleats is prevented from swinging left and right, and the curtain can hold beautiful pleats.

  Further, by forming the longitudinal cross-sectional shape of the connecting portion between the main rod and the insertion rod into an irregular cross-sectional shape in which the upper side gradually becomes thin, the thin-walled portion comes into contact with the lower end of the fold tack portion of the curtain. However, the deformation of the tack portion is smaller than that of the curtain suspending tool having a longitudinal cross-sectional shape of the conventional connecting portion, and beautiful folds are held on the curtain.

Further, when the cross-sectional shape of the connecting portion between the main rod and the insertion rod is formed in a teardrop shape in which the upper side is gradually thinned, the teardrop- shaped upper portion comes into contact with the lower end of the curtain fold tack portion. However, the deformation of the curtain is kept small and the beautiful folds of the curtain are retained.

  Further, when the cross-sectional shape of the insertion rod is formed in a rugby ball shape in which the main rod side and the non-main rod side are gradually thinned, the insertion rod is compared with the rectangular insertion rod. It is easy to insert into the fold tack, and the curtain hanger can be quickly and reliably attached to the curtain, and the bulge of the fold tack of the curtain after the curtain hanger is mounted is kept small. The beautiful folds of curtains are retained.

  In addition, when a blade part parallel to the curtain surface is formed on both the left and right sides of the main fence, the curtain hanging tool is supported by pressing the curtain with the blade part even if the curtain hanging tool swings to the left and right with respect to the curtain. The left and right sides of the curtain are prevented from shaking, and beautiful folds are held on the curtain.

  Also, a rack portion is formed on the main rod, and the hook body is formed separately from the main rod and has an engagement piece that elastically engages with the rack portion of the main rod and moves to the main rod. If the anti-rest part which clamps the said main shaft from both sides is provided in the position spaced apart from the engagement piece of the said hook body freely, this hook part will support a hook body by four points up and down. As a result, the hook body is prevented from swinging left and right with respect to the main rod as compared with the conventional support at the lower two points, and the beautiful folds of the curtain can be held.

Hereinafter, an embodiment of a curtain hanger used in the present invention will be described with reference to the drawings.

FIG. 1 shows a curtain hanger 10 used in the first embodiment of the present invention, where (a) is a front view, (b) is a left surface view, (c) is a rear view, and (d) is a plan view. (E) is a bottom view. 2 shows the main rod 11 of the curtain hanger 10 of FIG. 1, (a) is a front view, (b) is a left surface view, (c) is a rear view, (d) is a plan view, (e) Is a bottom view. 3 shows a hook body 13 of the curtain hanger 10 of FIG. 1, wherein (a) is a front view, (b) is a left surface view, (c) is a rear view, (d) is a plan view, and (e). Is a bottom view, and (f) is a partial front view of the main fence 11 on the curtain side.

  1 to 3, a curtain hanging tool 10 includes a main rod 11 cast-molded by a polymer resin, an insertion rod 12 connected integrally with the main rod 11 at the lower portion, a main rod 11 and The insertion rod 12 has a hook body 13 that is cast and formed separately from the insertion rod 12 and is slidable with respect to the main rod 11.

The main rod 11 rises vertically, and a plurality of rack portions 11a and 11b that are gradually thickened downward are formed on both left and right sides. Further, the blade portions 11c and 11d are formed so as to protrude in both the left and right directions. As the blade portions 11c and 11d are formed larger in the vertical direction and the horizontal direction, the effect of preventing the swing of the curtain hanger 10 described later becomes more prominent. On the other hand, the weight of the curtain hanger 10 increases and the use of resin is increased. Since the amount increases and the price increases, it is preferable to set the blade portions 11c and 11d to an appropriate size in terms of both the swing prevention effect of the curtain suspension 10 and the price of the curtain suspension 10. Further, as is clear from FIGS. 1A and 2A, the longitudinal cross-sectional shape of the connecting portion 14 between the main rod 11 and the insertion rod 12 is an irregular cross-sectional shape in which the upper side is gradually thinned, for example, a tear It is formed in a drop shape. Note that the connecting portion 14 in FIG. 1A is hatched (cross section) for convenience (FIGS. 2A, 4A, 5A, 6A, and 7). The same applies to (a).

  The insertion rod 12 is connected to the main rod 11 at the lower portion by a connecting portion 14 and is provided with a bent portion 12a that penetrates a hole provided in the curtain from the inside to the outside. The tip of the bent portion 12a is formed in a hemispherical shape so that it can be easily inserted into the hole of the curtain. Further, as is apparent from FIG. 1 (e), the cross-sectional shape of the insertion rod 12 is the main rod 11 side (right side in FIGS. 1 (e) and 2 (e)) and the non-main rod 11 side (FIG. 1). (E) and the left side in FIG. 2 (e) are formed into a rugby ball shape gradually becoming thinner.

The hook body 13 has an inverted U-shape as a whole having a side 13a inserted into the runner ring of the curtain rail and a side 13b attached to the main rod 11, and is inserted into the runner ring of the curtain rail. The distal end portion 13c of the side 13a is bent slightly outward and has a smaller diameter toward the distal end. Engagement pieces 13d and 13e that are elastically engaged with the rack portions 11a and 11b of the main rod 11 are provided on the left and right sides of the lower portion of the side 13b attached to the main rod 11. In addition, at the upper positions of the engagement pieces 13d and 13e, steadying portions 13f and 13g for holding the main rod 11 from both sides are provided. Furthermore, the front side of the side 13b attached to the main rod 11 is formed with a protruding portion 13h that protrudes toward the side 13a inserted into the runner ring of the curtain rail.

  Next, operation | movement of said curtain hanging tool 10 is demonstrated.

  First, the hook body 13 is mounted at an appropriate position on the main rod 11. The engaging pieces 13d and 13e of the hook body 13 are elastically engaged with the rack portions 11a and 11b of the main rack 11, and the hook body 13 is dropped from the main rack 11 by the step portions of the rack sections 11a and 11b. There is nothing. In this state, the curtain hanging tool 10 is attached to the tack portion for the folds of the curtain. At this time, since the cross-sectional shape of the insertion rod 12 is a rugby ball-like ellipsoidal shape, the insertion rod 12 can be smoothly placed on the tack portion of the curtain as compared with a curtain hanger having a rectangular cross-sectional shape. In addition to being able to be inserted, since the tack portion is rarely spread by the presence of the insertion rod 12 after being inserted into the tack portion, the tack portion is prevented from being deformed and disturbing the folds of the curtain. Beautiful folds are retained.

Further, the insertion rod 12 is inserted into the fold tack portion of the curtain by passing the hole provided in the curtain 12a of the insertion rod 12 from the inside to the outside and extending along the curtain. Compared to the one having only the protrusion or the protrusion inserted into the hole of the curtain, the left and right deflection of the insertion rod 12 with respect to the bent portion 12a of the insertion rod 12 and the main rod 11 of the entire insertion rod 12 is eliminated. The folds are retained. Furthermore, since the cross-sectional shape of the connecting portion 14 between the main rod 11 and the insertion rod 12 is formed in a teardrop shape in which the upper portion gradually becomes thin, the connecting portion 14 contacts the sewn portion of the tack portion of the curtain. Even so, compared to a conventional rectangular cross-sectional shape, the stress acting to deform the curtain seam is small, and the curtain is less deformed, so that the beautiful folds of the curtain can be maintained.

  In addition, since the blade 11c, 11d parallel to the curtain surface is formed on the main rod 11, by pressing the curtain surface with the blade 11c, 11d, there is no left-right swing of the curtain suspension 10 with respect to the curtain, Can hold beautiful folds of curtains.

  Further, since the anti-rest portions 13f and 13g for clamping the main rod 11 from both sides are provided above the engaging pieces 13d and 13e of the hook body 13, the engaging pieces 13d and 13e are simply provided at the lower portion of the conventional art. Compared to the hook body provided with only the hook body 13, the hook body 13 has a four-point support structure with respect to the main rod 11. Can be held. In the same manner as in the prior art, the hook body 13 is pushed downward so that the engagement pieces 13d and 13e can move on the rack portions 11a and 11b of the main rod 11 by a ratchet operation, and the hook body 13 can be moved to an arbitrary position. Can be located. When the hook body 13 is detached from the lower end of the main rod 11, it can be mounted from the upper end of the main rod 11 again.

  The above embodiment shows a typical one of the present invention, and the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention. Is possible.

For example, the curtain hanger used in the present invention is suitable for a hook body 13 as shown in the figure formed separately from the main rod 11 and movably attached to the main rod 11. It can also be applied to the body 13 formed integrally with the main rod 11.

In addition, the present invention has a configuration in which the bent portion 12a penetrating from the inside to the outside is provided in the hole of the curtain, that is, the longitudinal sectional shape of the connecting portion 14 between the main rod 11 and the insertion rod 12 is gradually thinner at the top. An irregular shape, for example, a teardrop shape, a cross-sectional shape of the insertion rod 12 is formed in a rugby ball shape in which the main rod 11 side and the non-main rod 11 side are gradually thinned, Forming the blade portions 11c and 11d on the left and right sides, forming the steady rest portions 13f and 13g on the hook body 13, and forming the protruding portion 13f on the front surface of the main rod 11 include one or more of them. It can be selectively employed.

4 and 5 show curtain suspenders 10a and 10b used in the second and third embodiments (the hook body is omitted) of the present invention, respectively. The same parts as those in FIG. 1 is different from the curtain hanger 10 of FIG. 1 in that the intermediate portions 18a and 18b of the insertion rod 12 are bent in a dogleg shape so as to abut against the main rod 11, and inserted into the distal end portion of the main rod 11. The recesses 19a and 19b for partially receiving the straight portion (bent portion 12a) at the tip of the flange 12 in the thickness direction are formed. In FIG. 4, the main rod 11 and the insertion rod 12 are connected. As is clear from FIG. 4A, the vertical cross-sectional shape of the portion 14a is formed in a rugby ball shape in which both upper and lower ends are sharp like the cross section of the rising portion shown in FIG. In this case, the vertical cross-sectional shape of the connecting portion 14b between the main rod 11 and the insertion rod 12 is formed in a flat hexagonal shape with its upper and lower ends sharpened in a triangular shape as is apparent from FIG. .

  Since the intermediate portions 18a and 18b of the insertion rod 12 are bent in a U shape so as to contact the main rod 11, the cloth of the tack portion of the curtain is sandwiched between the main rod 11 and the insertion rod 12. The inclination of the insertion rod 12 is suppressed. In addition, by receiving the bent portion 12a in the recesses 19a and 19b of the main rod 11, a sufficient force to sandwich the cloth of the tack portion of the curtain between the main rod 11 and the insertion rod 12 is obtained. Suppresses the tilt more reliably.

  Moreover, in 2nd Embodiment of FIG. 5, the rib 17 is formed along the edge part by the center of the both sides | surfaces of the insertion rod 12 being thinned. As a result, the rigidity of the insertion rod 12 is increased, and the inclination of the insertion rod 12 can be suppressed, and a sufficient force can be maintained to pinch the fabric of the tack portion of the curtain.

FIG. 6 shows a curtain hanger 10c used in the fourth embodiment (the hook body is omitted) of the present invention. The same parts as those in FIG. 1 differs from the curtain hanger 10 of FIG. 1 in that the intermediate portion 18c of the insertion rod 12 is inclined and close to the main rod 11, and the arcuate portion 18d in which the tip of the insertion rod 12 is concave on the main rod 11 side. FIG. 6 shows that the narrow portion 18e is narrowed in the width direction and the spherical portion 18f is located immediately above the front end 11e of the main rod 11, and the longitudinal sectional shape of the connecting portion 14c between the main rod 11 and the insertion rod 12 is shown in FIG. As apparent from (a), the upper and lower ends are formed in a rugby ball shape, and the hole 11f penetrating in the width direction is formed in the lower end of the main rod 11.

  Since the arc-shaped portion 18d and the spherical portion 18f are formed at the tip of the insertion rod 12, the tip of the insertion rod 12 inserted into the fold tack portion formed on the curtain is projected outward from the hole of the tack portion. Cheap. At this time, the cloth around the hole in the tack portion is less likely to be wrinkled because the arc-shaped portion 18d avoids the cloth, and the spherical portion 18f is prevented from being separated from the main rod 11. Therefore, the appearance of the curtain or curtain hanging tool 10c is preferable. The holes 11f are used to equalize the spacing between the curtain suspenders 10c when the curtains are closed with a plurality of curtain suspenders 10c mounted on the curtain. The holes 11f are thin ropes or wires. A cord-like body such as the above is inserted, and a stopper is attached to the cord-like body at equal intervals to regulate the interval between the curtain hanger 10c.
