There are two hanging points Q1 and Q2 on the pulley 23 of the operating string 24. Both hanging points Q1 and Q2 are disposed on the indoor side from the shielding material arranging plane Z. For this reason, the operation string 24 is disposed on the indoor side of the shielding material disposition plane Z in a state of being suspended from the pulley 23.

  Also, in FIG. 8, the reference numerals other than those described above and the same reference numerals as in FIG. 4 have the same configuration as in FIG.

  10 and 11 show a window shielding device 1D according to a fourth embodiment of the present invention. In FIG. 10, a member indicated by reference numeral 34 attached to the upper part of the window frame 2 is an exterior member of the lifting mechanism 5. The exterior member 34 also functions as the decorative member 3 and is disposed in an exposed state in the room. Therefore, the decorative member is not separately provided on the indoor side surface of the exterior member 34. In addition, a design surface may be formed by applying a decorative pattern to the interior side surface 35a of the exterior member 34 (see FIG. 11). Thus, by integrally configuring the exterior member 34a and the decorative member 3 of the elevating mechanism 5, the number of parts can be reduced, and the manufacturing cost can be reduced and the apparatus can be made compact.

  As shown in FIG. 11, the exterior member 34 has a long main body 35. The long main body 35 is formed by extruding an aluminum material, for example. However, the raw material and the processing method of the elongate main-body part 35 are not limited to this. The long main body portion 35 is formed to have a length corresponding to at least the lateral width of the shielding material 4, and the upper end edge of the shielding material 4 is attached to the lower end edge of the long main body portion 35. Further, the opening portions at both ends of the elongated main body portion 35 are closed by cap members (not shown). Thereby, the winding member 21 etc. accommodated in the elongate main-body part 35 cannot be seen from the outside.

  10 and 11, the same reference numerals as those in FIGS. 8 and 9 indicate the same members or the same parts as those in FIGS.

FIG. 12 shows a window shielding apparatus 1E according to the first reference example of the present invention. In the window shielding device 1E of the first reference example , the elevating mechanism 5 is disposed in the window frame 2 on the outdoor side of the shielding material disposition plane Z. Thereby, the hanging point P of the lifting / lowering string 6 in the lifting / lowering mechanism 5 is disposed on the outdoor side of the shielding material placement plane Z.

  The operation string 28 extending from the elevating mechanism 5 is suspended through an operation string guide 29 disposed in the recess 3 b of the decorative member 3. The operation string guide 29 is disposed on the indoor side of the shielding material disposition plane Z. Thereby, the hanging point Q of the operation string 28 in the operation string guide 29 is also disposed on the indoor side from the shielding material disposition plane Z.

The operation string guide 29 in the first reference example can be composed of one or a plurality of guide rollers, guide bars, guide pieces, or other guide means. In addition, the operation string 28 may be either configured integrally with the lifting string 6 or configured as a member separate from the lifting string 6.

  Also, in FIG. 12, the reference numerals other than those described above and the same reference numerals as in FIG. 4 have the same configuration as in FIG.

FIG. 13 shows a window shielding device 1F according to a second reference example of the present invention. FIG. 13A is a side view of the window shielding device 1F of the second reference example , in which the right side is the outdoor side and the left side is the indoor side. Moreover, (b) of FIG. 13 is the front view which looked at the said window shielding apparatus 1F from the indoor side.

  As shown in FIG. 13A, the window frame 2 is provided so as to protrude from the indoor wall surface 30. The shielding member 4 is suspended from the indoor side surface of the window frame 2 in close contact or close proximity. An elevating mechanism 5 for elevating and lowering the shielding material 4 is disposed on the back side of the shielding material 4 and inside the window frame 2.

The window shielding device 1 </ b > F of the second reference example includes an operation string 31 for raising and lowering the shielding member 4 via the lifting mechanism 5, as in the above embodiment. The operation string 31 penetrates the window frame 2 from the lifting mechanism 5 and is suspended from the side surface of the window frame 2. As described above, the operation string 31 may be disposed on the outdoor side of a shielding material arrangement plane (not shown) including a plane on which the shielding material 4 is arranged. However, in the second reference example , as shown in FIG. 13B, the operating string 31 is not shielded from being arranged on the back side of the shielding material 4, and is viewed from the indoor side. 4 is exposed and disposed at a position that does not overlap 4 (outside the width of the shielding material 4).

FIGS. 14A and 14B show a window shielding device 1G according to the fifth embodiment of the present invention. In this embodiment, the decorative member 3 is attached to the upper part of the window frame 2 protruding from the indoor wall surface 30. An elevating mechanism 5 is disposed in the decorative member 3, and an operation string 32 extends from the elevating mechanism 5. The operation string 32 is guided and suspended from the elevating mechanism 5 to the outside of the window frame 2 through the operation string guide 33. Similarly to the window shielding apparatus 1F of the second reference example , the window shielding apparatus 1G of the fifth embodiment also has the operation string disposed on the outdoor side of the shielding material arrangement plane (not shown). In addition, the window shielding apparatus 1G of 5th Embodiment makes an operation string penetrate the window frame like the window shielding apparatus 1F of a 2nd reference example by guiding the operation string 32 using the guide 33 for operation strings. You do n’t have to.

In each of the window shielding devices 1F and 1G of the second reference example and the fifth embodiment, configurations other than the above-described portions are the same as those of the window shielding device 1A of the first embodiment. In addition, as an operation string provided in the window shielding devices 1F and 1G of the second reference example and the fifth embodiment, an operation string integrated with the lifting string, or an operation string (such as a ball chain) made of a member separate from the lifting string. Both can be applied. Moreover, various guide means are applicable as the operation string guide 33 in the fifth embodiment.

  The window shielding apparatus 1A according to the first embodiment of the present invention described with reference to FIGS. 1 to 5 suspends the operation string 6a by arranging the elevating mechanism 5 on the indoor side of the shielding material arrangement plane Z. The point Q is disposed indoors from the shielding material disposition plane Z. Thereby, since the operation string 6a is arrange | positioned indoors rather than the shielding material arrangement | positioning plane Z, the user can hold | grip the operation string 6a easily. In the conventional window shielding apparatus described with reference to FIGS. 15 and 16, the operation string is disposed on the back surface of the shielding material. Therefore, when lifting the shielding material, turn the hand to the back surface of the shielding material. It had to be gripped and was difficult to operate. On the other hand, according to the window shielding apparatus 1A of the present invention, the user can easily grasp the operation string 6a, and therefore the raising / lowering operation of the shielding material 4 becomes much easier.

  Moreover, as shown in FIG. 2 etc., it is preferable to arrange the operation string 6a at a position where it does not overlap with the shielding material 4 (outside the width of the shielding material 4) when viewed from the indoor side. When the operation string 6a is disposed at a position overlapping the shielding material 4, when the shielding material 4 is lifted, the bent shielding material 4 interferes with the operation string 6a, making it difficult to operate the operation string 6a. Because it becomes. Therefore, by disposing the operation string 6a at a position that does not overlap the shielding material 4, it is possible to completely avoid the bent shielding material 4 from interfering with the operation string 6a when the shielding material 4 is lifted. Can do. As a result, a smoother lifting / lowering operation of the shielding material is possible.

  On the other hand, when the lifting / lowering string 6 is hung from the indoor side surface of the shielding material 4, the appearance of the lifting / lowering string 6 deteriorates, so it is necessary to dispose the lifting string 6 on the back surface of the shielding material 4. Therefore, the lifting / lowering string 6 is guided to the back side of the shielding material 4 via the lifting / lowering string guide 11. Moreover, by arranging the hanging point P of the lifting / lowering string 6 in the lifting / lowering string guide 11 on the outdoor side of the shielding material disposition plane Z, a force in the outdoor direction is applied to the lifting / lowering string 6, The window frame 2 can be securely adhered. Thereby, improvement of light-shielding property, indoor heat retention, etc. can be aimed at.

  The first embodiment is also applied to each of the window shielding devices according to the second embodiment shown in FIGS. 6 and 7, the third embodiment shown in FIGS. 8 and 9, and the fourth embodiment shown in FIGS. 10 and 11. The same operation and effect as the window shielding apparatus 1A according to the embodiment can be obtained.

Further, the window shielding device 1E of the first reference example shown in FIG. 12 is different from the window shielding device 1A of the first embodiment in that the elevating mechanism 5 is placed in the window frame 2 outside the shielding material disposition plane Z. It is arranged. By arranging the lifting mechanism 5 in the window frame 2 in this way, the number of members protruding from the window frame 2 to the indoor side is reduced, and the decoration member 3 can be made compact. As a result, the room becomes wider and the appearance is improved. Further, by arranging the hanging point P of the lifting / lowering string 6 in the lifting / lowering mechanism 5 on the outdoor side from the shielding material-disposing plane Z, a force in the outdoor direction is applied to the lifting / lowering string 6 in the same manner as described above, thereby 4 can be securely adhered to the window frame 2. On the other hand, since the operation cord 28 is guided and suspended indoors from the shielding material placement plane Z by the operation cord guide 29, the user can easily grasp the operation cord 28 in the same manner as described above. It is possible to perform the raising / lowering operation of the shielding material 4.

Also, in each of the window shielding devices according to the second reference example shown in FIG. 13 and the fifth embodiment shown in FIG. 14, the operation string is exposed to the indoor side, so that the user can easily grasp the operation string. This makes it easier to lift and lower the shielding material.

  For example, in the conventional window shielding apparatus shown in FIG. 16, of the three lifting strings 400 disposed on the back surface of the shielding material 300, two lifting strings disposed near the vertical edges on both sides of the shielding material 300. It is desirable to arrange 400 at a position close to each vertical edge of the shielding member 300. This is because if the lifting / lowering string 400 is disposed at a position away from the vertical edge of the shielding material 300, when the shielding material 300 is lifted, wrinkles are formed near the vertical edge of the shielding material 300 and the appearance is deteriorated.

  In the window shielding apparatus shown in FIG. 16, among the three lifting strings 400, the lifting string 400 disposed on the left side is moved to the left in the figure and hung at a position close to the vertical edge of the shielding material 300. In this case, the elevating mechanism (stopper) 600 must be disposed at a position that does not interfere with the guide mechanism 700 that suspends the elevating string 400. For example, interference with the guide mechanism 700 can be avoided by disposing the lifting mechanism 600 at a position on the left side of the extension line of the left vertical edge of the shielding member 300. However, since the conventional window shielding device has a structure in which the operation string 900 is disposed on the back side of the shielding material 300, only the lifting mechanism 600 is disposed on the left side of the extension line of the vertical edge of the shielding material 300. It is difficult.

  On the other hand, the window shielding apparatus of this invention is comprised so that an operation string may be arrange | positioned indoors or outside the width | variety of a shielding material rather than a shielding material. For this reason, the raising / lowering mechanism (stopper) can also be arrange | positioned indoors or outside the width | variety of a shielding material from a shielding material (illustration omitted). Therefore, even if the lifting strap is disposed at a position close to the vertical edge of the shielding material, the lifting mechanism can be disposed at a position where it does not interfere with the guide mechanism or the like of the lifting strap. As a result, the window shielding device of the present invention can employ a structure in which the lifting strap is brought close to the vertical edge of the shielding material without significant design change, and when the shielding material is lifted, the shielding material is wrinkled. It is possible to prevent it from happening and improve its appearance.
