Please refer to Figs. 2 to 6 again, and then refer to Figs. 3 to 6, the following describes the characteristics of the elastic support 36 and its connection with the second curtain surface 34:

The elastic support 36 may be a sheet-shaped body woven from but not limited to natural fibers, man-made fibers, synthetic fibers, etc., and may also be a flexible thin plate made of, but not limited to, plastic. In some embodiments, in order to avoid the possibility that the second curtain surface 34 sags or deforms due to the overall weight of the elastic support 36, the elastic support 36 may also have a plurality of through holes (not shown in the figure) penetrating through the front and rear surfaces. In this way, the material removal means can be raised before the effect of the elastic support 36 supporting the second curtain surface 34 is not affected, and the overall weight of the elastic support 36 can be effectively reduced.

In addition, the width of the elastic support 36 may correspond to the width of the second curtain surface 34, that is, the width of the two may be the same or substantially the same, but it is not limited thereto. In some embodiments, the elastic support 36 is connected to the upper portion 342 of the second curtain surface 34, but the actual application is not limited to this. The elastic support 36 can also be connected to the middle portion 344 or the middle portion of the second curtain surface 34. Lower part 346; in addition, for visual aesthetics, the elastic support 36 can be but not limited to the inner side 348 of the second curtain surface 34, that is, the elastic support 36 is arranged on the second curtain surface 34 facing the upper beam 10, so that the elastic supporting member 36 can be blocked by the second curtain surface 34 and is not easy to be directly viewed by the user.

Please refer to FIGS. 4, 6 and 7A. In some embodiments of the present creation, the curtain body 30 further includes four connecting members 38. The elastic support member 36 is connected to the second curtain surface 34 through the connecting members 38. The connecting members 38 are arranged longitudinally in pairs on opposite sides of the second curtain surface 34, but the actual application is not limited to this. For example, it is desired to connect the elastic support 36 and the second curtain surface 34. For this purpose, only one connecting piece 38 is actually needed; preferably, in other possible embodiments, when the number of connecting pieces 38 is two, the two connecting pieces 38 can be respectively arranged on the second curtain surface 34 On two opposite sides, one of the connecting pieces 38 is closer to the first curtain surface 32 on one side than the other connecting piece 38 (as shown in FIG. 7B). As a result, the two connecting pieces 38 not only have connecting elastic support pieces 36 And the effect of the second curtain surface 34 can also avoid the possibility of the elastic support 36 rotating or excessively rotating relative to the second curtain surface 34; or, when the number of the connecting members 38 is also two, the two connecting members 38 They are arranged on the second curtain surface 34 and arranged longitudinally, that is, the horizontal distances from the two connecting members 38 to the first curtain surface 32 on one side are the same (as shown in FIG. 7C). At this time, the two connecting members 38 It can be located at the center of the second curtain surface 34, but is not limited to this. Or, in another possible embodiment, the number of the connecting member 38 is only one, and the distance between the connecting member 38 and the first curtain surface 32 connected to both sides of the second curtain surface 34 is the same, that is to say At this time, the connecting piece 38 is located in the center of the second curtain surface 34 (in the figure Not shown). The number and installation positions of the connecting pieces 38 above are merely illustrative, and the actual application can be adjusted according to requirements.

It is added that the reason why the elastic support 36 and the second curtain surface 34 of the present creation are connected in a relatively movable but inseparable manner is that when the curtain body 30 is unfolded, folded or deflected, the second curtain surface The amount of change in the bending amplitude of 34 and the elastic support 36 is not the same. At this time, if the elastic support 36 is attached to the second curtain surface 34 as a whole, the two cannot move relative to each other. With the increase in the number of operations, the elastic support 36 will inevitably be deformed or detached from the second curtain surface 34 and disintegrated. It may also be caused by excessively supporting the second curtain surface 34, resulting in a light and transparent second curtain. The surface 34 is deformed, and the elastic support 36 of the present invention is relatively movable but inseparably connected to the second curtain surface 34, which can effectively improve the aforementioned disengagement and collapse.

In some embodiments, the connecting member 38 is a loop with a predetermined length, and it passes through the elastic support member 36 and the second curtain surface 34 at the same time to stitch or bolt the elastic support member 36 and the second curtain surface 34; wherein The connecting member 38 is made of a composite material composed of natural fiber, man-made fiber, synthetic fiber, silicone rubber, rubber, plastic or any mixture thereof; the aforementioned predetermined length provides the elastic support 36 and the second curtain surface 34 The degree of freedom of relative movement between the curtain body, so when the curtain body 30 is in the process of unfolding, folding or deflection, the elastic support 36 and the second curtain surface 34 have different bending amplitude changes, the predetermined length can be It is used for the relative movement of the elastic support 36 and the second curtain surface 34.

In other embodiments, the connecting member 38 is a line segment with a predetermined length, and two ends of the connecting member 38 respectively pass through and are fixed to the elastic support member 36 and the second curtain surface 34, wherein the connecting member 38 It is made of composite materials composed of natural fiber, man-made fiber, synthetic fiber, silicone, rubber, plastic or any mixture thereof. The predetermined length is also used for the relative movement of the elastic support 36 and the second curtain surface 34, which will not be repeated here.

In other possible embodiments, the connecting member 38 is an elastic body, the connecting member 38 is located between the elastic supporting member 36 and the second curtain surface 34, and both ends of the connecting member 38 are respectively connected to the elastic supporting member 36 The side opposite to the second curtain surface 34, wherein the connecting member 38 is made of a composite material composed of silicone, rubber, plastic or any mixture thereof; in these embodiments, when the curtain is expanded and folded Or during a yaw movement, the elastic support member 36 and the second curtain surface 34 can move relative to each other through the elasticity of the connecting member 38.

However, it should be emphasized that the aforementioned elastic support 36 and the second curtain surface 34 are connected in a relatively movable but inseparable manner, and it does not only refer to the state where the entire elastic support 36 and the second curtain surface 34 are relatively movable. In this way, it actually includes the aspect that only a part of the elastic support 36 can move relative to the second curtain surface 34. For example, when the number of connecting members 38 is one or the number of connecting members is two but they are arranged at the center of the second curtain surface 34, even if the connecting members 38 directly tightly fix the elastic support 36 on the back of the second curtain surface 34 The place where the elastic support 36 is fixed on both sides of the first curtain surface 32 relative to the connected member 38 can be regarded as a free end, that is, the elastic support 36 can move relative to the second curtain surface 34 but cannot be separated. In the aspect, when the curtain body 30 is manipulated so that the bending amplitude of the second curtain surface 34 changes correspondingly, the elastic support 36 will not move relative to the second curtain surface 34 except for the tightly fixed position by the connecting member 38. , The other areas of the elastic support 36 will move correspondingly to the second curtain surface 34.

In some embodiments, the stiffness of the elastic support 36 is greater than that of the second curtain surface 34, and a material with greater stiffness is used to have better flexural rigidity and not easy to bend, so that the elastic support 34 maintains the second The shape of the curtain surface 34; in other possible embodiments, the elastic support 36 may be made of, but not limited to, a plastic material, which is generally a thin plate. Within its elastic limit, the elastic support 36 can be implemented Given the difference in the magnitude of the external force, the bending changes of different amplitudes are generated, and the original shape is restored after the external force is removed. Therefore, it can also provide sufficient support for the second curtain surface 34 when the first curtain surface 32 is folded During stacking, the second curtain surface 34 is supported by the elastic support member 36 and can maintain a non-V-shaped arc-shaped curve, so that the second curtain surface 34 does not produce permanent creases.

In addition, in other possible embodiments, in order to allow the upper part 342 of the second curtain surface 34 to bear the weight of the middle part 344 and the lower part 346 without sagging or twisting, it is better to provide the elastic support 36 and the connecting part 38 The fixing effect prevents the connecting member 38 from being unable to reliably fix the elastic support member 36 on the second curtain surface 34, and also prevents the light-weight second curtain surface 34 from being pulled and damaged by the connecting member 38 and the elastic support member 36 The upper part 342 of the second curtain surface 34 can further increase its supportability by increasing the thickness. For example, by adhering lining cloth to the upper part 342 of the second curtain surface 34, or using different weaving methods to make the upper part 342 of the second curtain surface 34 thicker, to ensure that the upper part 342 of the second curtain surface 34 is not affected by the load. The elastic support 36 can be deformed, and the elastic support 36 can be more firmly bonded to it. At the same time, the elastic support 36 can be arranged on the side covered by the lining cloth or thick tissue, so that the elastic support 36 can be blocked and not easily used. Those who look directly at it can achieve the purpose of enhancing visual beauty.

In conclusion, the vertical curtain 1 of this creation has at least the following advantages:

(1) The combination of the first curtain surface, the second curtain surface and the elastic support can effectively prevent the curtain body from excessively bending the second curtain surface during folding and stacking, so that the second curtain surface can be prevented from being compressed The possibility of creases due to deformation allows this creation to maintain its existing appearance for a long time.

(2) The form of the connecting piece and its position on the second curtain surface can be selected according to requirements. For example, the user can choose a suitable one according to the convenience of processing or the color and appearance of the second curtain surface. The connecting piece form (rope loop, line segment or elastic body) and the setting position of the connecting piece are hidden on the second curtain surface without being abrupt.

(3) With proper materials, the elastic support can be removed by means of removing materials, so that the elastic support has a plurality of through holes passing through the front and rear sides of the elastic support, which can effectively reduce the overall weight of the elastic support and avoid sagging or twisting of the second curtain surface Case.

Finally, it must be stated again that the constituent elements disclosed in the foregoing embodiments of this creation are only examples, and are not used to limit the scope of the creation of the patent. For example, any simple structural modifications or changes made without going beyond the spirit of this creation, or The replacement with other equivalent components should still fall within the scope of the patent application for this creation.
