Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain for lifting curtains and its rails, cord guides and attachment means, and more particularly to a bay window having an arcuate shape, a trapezoidal shape or a V shape projected on an outer wall. The present invention relates to a hanging curtain type curtain to be erected, its rail, a string guide, and a mounting means.

[0002]

2. Description of the Related Art A conventional curtain of this type is provided with a rail having a tubular cross section, which is formed in accordance with the shape of a bay window. A plurality of holes or slits along the rail axis are formed on the lower surface of the rail, and a curtain cloth is hung on the lifting string hanging from the holes or slits.
A pulley around the rail axis is arranged inside the rail, and the upper part of the lifting string is wound around the pulley.

On the other hand, a ring-shaped operation cord is hung on the left and right ends of the rail, and by pulling down either the left or right part of the operation cord, the pulley rotates to wind up or down the lifting cord. The curtain cloth is extended and the curtain cloth is opened and closed in accordance with this. As described above, since the rail needs mechanical strength capable of supporting the internal pulley, it is made of metal such as steel having an appropriate thickness.

[0004]

The bay window has an arc shape in plan view,
Since it is formed in a curved shape such as a trapezoidal shape or a V shape, it is necessary to bend the rail when laying a lifting curtain type curtain on such a bay window, and usually a linear shape cut on several sides Rails are joined to fit the contour of the bay window.

However, since the rail itself is made of a metal having a considerable wall thickness, it is not easy to cut and join, and furthermore, one or a plurality of pulleys are incorporated in each side, and the entire pulleys are incorporated. Must be configured to work with the operating string. Furthermore, since the curtain cloth is suspended along the lower surface of the rail, and the rail is exposed above the curtain cloth, it is necessary to give due consideration to the appearance of the cut surface and the joint portion of the rail. Furthermore, since there is no unified standard in the specifications of the bay windows, and various shapes and sizes exist for each building, it is necessary to measure the dimensions of each bay window and manufacture it in a customized manner.

Therefore, conventionally, the production and construction of this type of lifting curtain has been extremely complicated, the construction period has been lengthened, and the price has become expensive. Therefore, in order to make the lifting curtain type easy to manufacture and construct, it is possible to freely adapt to a wide variety of bay windows, and without lowering the appearance, and to further reduce costs. A technical problem to be solved arises, and an object of the present invention is to solve the problem.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIG.
This will be described in detail with reference to FIG. Figure 1 shows a curtain with a curtain
FIG. 3 is a perspective view showing a state of being installed on an exit window (not shown) having an arc shape in plan view, as viewed from the outside of the exit window (the rear side of a rail described later). As shown in the figure, the rails 2 of the curtain 1 have a rail 2a on the left side of the paper surface and a rail 2b on the right side of the paper surface in series at the center via two connecting members 3 (3a, 3b). It is configured by being connected. Also,
On the back surface of the rail 2, five fixtures 4, 4, ... And four string guides 5, 5, ... Are respectively arranged at predetermined positions.

A cord insertion opening 7 for inserting the cord 6 is formed in the connecting tools 3, 3 and the cord guides 5, 5 ... And the outside of the cord insertion port 7 of the leftmost cord guide 5. Three strings 6, 6 and 6 are inserted from (the left side of the paper), one of the strings 6 is hung from the right outer edge of the string guide 5 at the leftmost end, and the other two strings 6, 6. 6 are both pulled along the back surface of the rail 2 and are sequentially inserted into the right string guide 5 and the string insertion port 7 of the connecting tool 3a. Then, one of the strings 6 hangs down from the right outer edge of the connecting tool 3a, and the remaining one string 6 further traces to the right along the back surface of the rail 2 to sequentially connect the connecting tool 3b and its right side. Of the cord guide 5 and the cord insertion port 7 of the leftmost cord guide 5, and is hung from the right outer edge of the cord guide 5 of the rightmost end. These 3
Reference numeral 6a is attached to the hanging portions of the strings 6, 6, and 6 of the book.

Here, as shown in FIG. 2, the rail 2 has an ultrathin steel plate 8 as a core member provided therein, and a synthetic resin film 9 is provided around the steel plate 8 and The upper end of the coating film 9 and the vicinity of the upper end thereof and the lower end thereof project to the left and right to form the thin grooves 10 and 10 and the concave portions 11 and 11 and are formed in a thin plate shape having a substantially I-shaped cross section. Therefore,
The rail 2 is flexible and can be freely curved according to the contour of the bay window.

The attachment 4 is a curtain curtain 1
A bracket for directly arranging (directly the rail 2) on a bay window, which is formed of steel in a U-shaped cross section and an L shape in a side view, and a hook 12 is provided at a base end portion of the bracket. The hook 12 is engaged with the narrow groove 10 on the front side of the rail 2 (on the left side of the drawing). Further, a pressing block 14 made of synthetic resin is provided with screws 15 near the base end of the upper wall 13 of the fixture 4.
And a claw 16 is projected from the end side of the holding block 14 on the base end side.
Is engaged with the narrow groove 10 on the back side (right side of the drawing). Then, when the screw 15 is tightened, the claw 16 is pressed against the rear upper end raised portion of the rail 2, so that the fixture 4 is fixed to the rail 2. Further, if the screw 15 is loosened slightly, the fixture 4 can be slid along the upper surface of the rail 2. Further, by loosening the screws 15 and removing the pressing block 14, the fixture 4 and the rail 2 can be separated. In this way, the mounting tool 4 is formed so as to be attachable to and detachable from the rail 2 at an arbitrary position and slidable.

Further, round holes 18, 18 are formed in the upper side wall 13 and the rear side wall 17 of the fixture 4, respectively. Therefore, when the hoisting curtain 1 is installed on the horizontal plane of the upper edge of the bay window, the upper side wall 13 of the fixture 4 is brought into contact with the horizontal plane, and the round hole 18 formed in the upper side wall 13 is screwed. If the rails are tightened, the rail 2 can be mounted in a standing state in the width direction. On the other hand, when the hoisting curtain 1 is to be installed on the vertical plane of the upper edge of the bay window, the rear side wall 17 of the fixture 4 is brought into contact with the vertical plane to form the round hole 18 formed in the rear side wall 17. If the screws are tightened, the rail 2 can be mounted in a state of standing in the width direction in the same manner.

Next, the specific structure of the cord guide 5 will be described with reference to FIG. The string guide 5 is formed of a synthetic resin in a box shape, and two front and rear openings are provided in the horizontal direction. Of the openings, the front one (in the direction toward the back of the paper) is the rail insertion opening 19, and the rear one is the cord insertion opening 7. Further, a screw hole 20 is opened at the center of the lower surface of the rail insertion opening 19. The inner shape of the rail fitting opening 19 is formed in accordance with the cross-sectional dimension of the rail 2, and by inserting the rail 2 through the rail fitting opening 19, the cord guide 5 is slidable along the rail 2. Is formed in. Then, from the bottom of the screw hole 20, the screw 2
When 1 is screwed, the tip of the screw 21 is pressed against the lower end surface of the rail 2, so that the cord guide 5 is fixed at an arbitrary position on the rail 2.

On the other hand, as will be described later, when the curtain is opened and closed, the cord 6 reciprocates between the left and right outlets of the cord insertion opening 7 and rubs against the inner bottom surface of the cord insertion opening 7. Thus, the inner bottom surface has a curved center portion 22 which is bulged at the center in a circular arc shape when viewed from the front. As a result, the frictional force acting on the string 6 is reduced, so that not only the force required for the curtain opening / closing operation can be reduced, but also the deterioration of the string 6 can be prevented.

Next, a specific structure of the connecting tool 3 will be described with reference to FIG. The connecting tool 3 has a function of connecting the rail 2a and the rail 2b, and also has a role of a string guide.
Like the string guide 5, it is molded in a box shape from a synthetic resin, and has a rail insertion opening 19 and a string insertion opening 7 in the horizontal direction. However, unlike the string guide 5, the connecting tool 3 has two rail fitting openings 19 arranged side by side. Then, two such connecting tools 3 are prepared, and as shown in FIG. 1, each of the rail fitting insertion ports 19 in the front row (the deepest direction in the drawing).
The left end portion of the rail 2b is inserted through the rail 2a, and the right end portion of the rail 2a is inserted through the central rail insertion opening 19 to connect both rails 2a and 2b.

Initially, with respect to the left-hand connecting member 3a,
A screw 21 is placed in the screw hole 20 on the lower surface of the rail insertion opening 26 in the front row.
Screwing and tightening to fix the connecting tool 3a and the rail 2b,
On the other hand, the connecting tool 3a and the rail 2a are made slidable. On the contrary, for the right-hand side coupling tool 3b,
A screw 21 is screwed and tightened in a screw hole 20 on the lower surface of the center rail insertion opening 19 to fix the connecting tool 3b and the rail 2a, and the connecting tool 3b and the rail 2b can slide. . As a result, when the rail 2 is installed on the bay window,
By adjusting the left and right positions of the rails 2a and 2b according to the upper edge size of the bay window, the rail 2 can be freely expanded and contracted. Then, when the upper edge dimension of the bay window and the length of the rail 2 match, the connecting tool 3a is inserted into the screw hole 20 of the central rail fitting insertion opening 19 and the connecting tool 3b is inserted into the front row rail fitting insertion opening 19. Screw 2 in each screw hole 30
1 is screwed and tightened to fix the length of the rail 2.

When the length of the rail matches the length of the bay window from the beginning, or when the rail is long and has a means for cutting the rail in accordance with the length of the bay window. In this case, naturally, it is not necessary to form the rails so as to be extendable and contractable as in the present embodiment, and a single curtain can constitute the curtain for lifting curtains. On the other hand, as described above with reference to FIG. 2, since the steel plate 8 is provided inside the rail 2, a special tool such as an iron cutter is required to cut the steel plate 8. Therefore, the present embodiment is extremely effective in the case where a general user who does not have such a tool constructs a do-it-yourself carpenter.

FIG. 5 shows another embodiment of the connector. As shown in FIG.
Is formed into a substantially U-shape when viewed from the side according to the cross-sectional dimension of the rail 2, and its upper and lower tips are folded back inward,
It engages with the rear side narrow groove 10 of the rail 2 and the protruding portion on the rear surface of the lower end portion. Then, as shown in FIG. 3B, the rails 2a and 2b are fitted and inserted on the left and right sides of the connecting tool 23 to adjust the mutual positions. As a result, the rail 2 is connected to the connecting member 23.
It can be expanded or contracted by the length of. By the way, the upper edge dimensions of commercially available bay windows are not uniform depending on manufacturers, but most bay windows are within a range of tens of centimeters in size difference. Therefore, it is sufficient if the connecting tool 23 is formed to have a length corresponding to this dimensional difference.

As shown in FIG. 2, a planar fastener hook 24 is provided in the recess 11 on the front side of the rail 2, and as shown in FIGS. 3 and 4 (or FIG. 5 (a)). As shown in the drawing, the surface fastener hooks 24 are also arranged on the front surfaces of the cord guide 5 and the connecting tool 3 (or 23), respectively. Therefore, in FIG. 1, the planar fastener hooks 24 are provided over the entire left and right sides of the front surface of the skeleton of the curtain-type curtain 1, which is composed of the rails 2, the connecting members 3, the mounting members 4 and the string guides 5. Has been done. Then, after the skeleton is installed on the upper edge of the bay window, the curtain cloth 25 is hung on the skeleton.

On the other hand, the upper edge of the curtain cloth 25 is sewn to form a gather 26. A planar fastener eye 27 is sewn on the back surface of the gather 26 over the entire length. Therefore, if the planar fastener eye 27 and the planar fastener hook 24 are bonded together,
The curtain cloth 25 can be suspended very easily.
Moreover, since the gathers 26 cover the front surface of the rail 2 and the skeleton of the curtain-type curtain 1 cannot be seen from the room, the function of the curtain-type curtain 1 as an interior decoration is further enhanced. To be
