【Example】

 As shown in FIGS. 1 and 2, an accordion curtain used in a glass window, a door, etc. according to a first embodiment of the present invention is a curtain sheet 2, a pair of first fixing means 31, 32 including a suction cup, The upper rail thread 41, the lower rail thread 42, and a pair of second fixing means 51, 52, which are suction cups like the first fixing means 31, 32, are provided.

The curtain sheet 2 has a large number of folds 21 flexibly connected to each other, and can be folded in a bellows shape in the left-right direction (sideways). The folds 211 and 212 located at both ends of the curtain sheet 2 in the left-right direction are made of a relatively hard material such as plastic and have a relatively large wall thickness. The folds 21 other than the folds 211 and 212 at the both ends are formed of a relatively thin material such as paper or plastic, as long as the awning effect can be obtained. An upper side through hole 221 and a lower side through hole 222 are formed in the corresponding positions on the upper end side and the lower end side of each fold piece 21, 211, 212, respectively. Further, friction holes 231 and 232 are provided at positions inside the upper side through hole 211 and the lower side through hole 212, respectively, in the fold piece 211 at the left end portion of the curtain sheet 2 shown in FIG.

The first fixing means 31 and 32 are suction cups, and are attached to the upper end and the lower end of the fold piece 212 at the right end of the curtain sheet 2 shown in FIG. 1, respectively. The first fixing means 31 and 32 are sucked and fixed to the window glass 6 such as the windshield glass of the vehicle, the door of the building, and the window glass of the sunshade by the accordion curtain. The first fixing means 31 and 32 are not limited to suction cups, and may be fixing means such as an adhesive band or a double-sided adhesive band.

The upper rail yarn 41 and the lower rail yarn 42 are made of a material such as nylon yarn having a smooth surface, and are inserted into the upper through hole 221 and the upper through hole 222 of the curtain sheet 2, respectively. . One ends of the upper rail yarn 41 and the lower rail yarn 42 are fixed to a fold piece 212 at the right end.

The other end of the upper rail thread 41 is inserted through the upper through hole 221 of the fold piece 211 at the left end of the curtain sheet 2, and the surface 211a from the front side in the figure to the surface 211b on the far side in the figure. The upper thread rail 41 extending from the upper through hole 221 is inserted into the friction hole 231 and returned to the front surface 211a again. Further, the upper rail thread 41 extending from the friction hole 231 is extended downward and extended from the lower through hole 222 of the fold piece 211 at the left end portion. The other end of the lower rail yarn 42 is inserted into the lower through hole 232 of the fold piece 211 at the left end portion of the curtain sheet 2 so as to move from the front surface 211a in the figure to the surface 211b on the far side in the figure. The lower thread rail 41 extending from the lower through hole 232 is inserted into the friction hole 232 and returned to the front surface 211a again. Further, the lower rail thread 42 extending from the friction hole 232 is extended upward and extended from the upper through hole 221 of the fold piece 211 at the left end portion.

In the present embodiment, the second fixing means 51, 52 are suction cups, and the upper rail thread 41 extending from the upper through hole 221 and the lower through hole 222 of the fold piece 211 at the left end portion. , The ends of the lower thread rails 42 are firmly fixed.

In the accordion curtain of this embodiment, as shown in FIG. 1, the first fixing means 31 and 32 are sucked and fixed to the right end portion of the window glass 6, while the second fixing means are fixed. The upper rail thread 41 and the lower rail thread 42 are attracted and fixed to the left end portion of the window glass 6 so that the upper rail thread 41 and the lower rail thread 42 are held in a linear state. In this embodiment, since the upper rail thread 41 and the lower rail thread 42 are made of a material such as a nylon thread having a smooth surface, each fold piece 21 of the curtain sheet 2 has the upper through hole 221 and the lower through hole 221 as described above. The upper rail thread 41 and the lower rail thread 42, which are inserted into the side through holes 222, can be smoothly moved to the extent that almost no resistance is felt, and the user can very easily hand-operate each of the curtain sheets 2. The folds 21 can be expanded and contracted.

Further, in the present embodiment, as described above, the friction holes 231 and 232 are provided in the fold piece 211 at the left end, and the upper rail yarn 41 and the lower rail yarn 42 are inserted into the friction holes 231 and 232. Therefore, the fold piece 211 at the left end can move the upper rail yarn 41 and the lower rail 42 while having an appropriate movement resistance. Since the resistance generated when the folds 211 move is generated by the same structure in the upper rail yarn 41 and the lower rail yarn 42, only the upper rail yarn 41 side will be described. That is, with the upper rail thread 41 being properly tensioned, the upper rail thread 41 is inserted into the upper through holes 221 of the folds 21 of the curtain sheet 2, and the folds 211 of the left end portion are inserted into the upper through holes 221. Since it is further inserted through the friction hole 231 into the lower through hole 222, the bent portion of the upper rail thread 41 comes into contact with the folds 211, so that it is inserted only through the upper through hole 221. Also has a large resistance to movement. Since the folds 21 on the left side end have movement resistance in this way, the folds 21 can be positioned at a predetermined position on the upper rail yarn 41 and the lower rail yarn 42, and the curtain sheet 2 is unfolded or expanded. The contraction can be maintained in the desired state.

Further, since the nylon yarns constituting the upper rail yarn 41 and the lower rail yarn 42 are elastic and tough themselves, the movement resistance of the folds 211 depends on the upper rail yarn at the time of assembly. 41, depending on the tension applied to the lower rail yarn 42. That is, when the upper rail yarn 41 and the lower rail yarn 42 are in a state in which higher tension is applied by the second fixing means 51, 52, the movement resistance of the fold piece 211 at the left end also becomes large. Therefore, the user can appropriately adjust the movement resistance of the folds 211 according to his / her preference.

The upper rail thread 41 and the lower rail are inserted into the friction holes 231 and 232 formed in the folds 211 (the folds at the left end in FIG. 1) that form the sliding end of the curtain sheet 2. The structure for bypassing the yarn 42 is not limited to the above-mentioned structure, and various different modes can be adopted. For example, even if the order of the bypass insertion of the upper rail yarn 41 and the lower rail yarn 42 is changed, the movement resistance can be similarly generated. Also, the number of friction holes to be drilled is not limited to two, and an appropriate number of friction holes are provided to allow the upper rail thread 41 and the lower rail thread 42 to penetrate therethrough to generate the necessary movement resistance. However, in this case, if the number of holes through which the upper rail yarn 41 and the lower rail yarn 42 are bypassed is too large, the movement resistance of the folds 211 at the left end portion becomes too large.

The accordion curtain of this embodiment having the above-mentioned configuration has a significantly smaller number of assembly members than the conventional accordion curtain of this type. Therefore, the accordion curtain of this embodiment is low in cost and easy to assemble. In addition, the accordion curtain of this embodiment can be used by expanding the entire curtain sheet 2 as shown in FIG. 1, and as shown in FIG. It can be used by unfolding it so as to shield the area of the curtain sheet 2. When the folds 21 of the curtain sheet 2 are completely folded and contracted, the state shown in FIG. You can adjust it to your liking.

In the second embodiment of the present invention shown in FIG. 5, mounting pieces 721 and 721 are integrally provided on the upper end side and the lower end side of the fold piece 72 at the right end of the curtain sheet 71, respectively. The first fixing means 31, 32 are attached to the mounting pieces 721, 721. Other configurations and operational effects of the second embodiment are the same as those of the above-mentioned first embodiment, and therefore description thereof is omitted. In the first and second embodiments, the window glass 6 for shielding the lengths of the upper and lower rail threads 41, 42 is provided in order to secure the shade effect and prevent the curtain sheets 7, 71 from loosening. The length corresponding to the width of the first and second fixing means 31, 32, 51, 52 is fixed to the four corners of the window glass 6 by suction, and tension is applied to the upper and lower rail threads 41, 42. It is held in the state and hung on the window glass 6. In the first and second embodiments, the lengths of the upper and lower rail threads are set in accordance with the width dimension of the window glass at the time of manufacture in order to be used for the window glass having different width dimensions depending on the vehicle type and the like.

In addition, a mating surface 823 that engages with a mating surface 812 provided at the open end of the base 81 is provided on the inner surface of the rotary grip portion 822. A spring 85 formed of a spiral spring is contracted between the rotation knob 82 and the fixed seat 83. With this spring 85, the meshing surface 823 of the rotary grip portion 822 is meshed with the meshing surface 812 of the base 81. Is urged to.

The upper rail yarn 42 and the lower rail yarn 43 have one end (the end on the right side in FIG. 7) on the first fixing means 31, 32, as in the first and second embodiments. It is fixed, and the other end (the end on the left side in FIG. 7) is wound around the recessed groove 821 of the rotation knob 82 of the second fixing means 51, 52.

When the third embodiment is used, the first and second fixing means 31, 32, 51 and 52 are sucked and fixed to the four corners of the window glass 6. When changing the distance between the first fixing means 31 and 32 and the second fixing means 51 and 52, that is, the widthwise dimension of the accordion curtain, the first fixing means is fixed at a desired position on the window glass 6. The means 31 and 32 and the second fixing means 51 and 52 are fixed by suction. When the upper rail thread 41 and the lower rail thread 42 are loosened by narrowing the gap between the first fixing means 31 and 32 and the second fixing means 51 and 52, the rotary grip portion 822 is pinched and rotated. The knob 82 is rotated, and the upper rail thread 41 and the lower rail thread 42 are wound around the recessed groove 821 of the rotary knob 82 to adjust the tension. The meshing surface 812 of the base 81, the meshing surface 823 of the rotation knob 82, and the spring 85 constitute a clutch mechanism, and the upper grip thread 41 and the lower grip thread 42 are provided with appropriate tension, and the rotary grip portion is provided.
