  In the pleated screen 20 shown in FIGS. 1A to 1C, the screen S is suspended and supported from a head box 21 attached to a window frame or the like. The screen S can be folded in a zigzag shape (mountain folding and valley folding bellows) in the vertical direction, and by operating an operation code 23 assembled to an operation device (not shown) mounted on the head box 21. It can be moved up and down. The amount of light collected from the window can be appropriately adjusted by this elevation.

  As shown in FIG. 1 (b), the screen S has slits (cuts) t across both ends on both surfaces of a plate member P having a hollow structure, and a surface at predetermined intervals in the vertical direction (direction perpendicular to the slit t). They are formed alternately on the back surface. The slit t is inserted from one surface side of the plate material P, but does not penetrate the other surface side, so that the other surface side of the back of the slit t of the plate material P is connected. The shape in which the other surface side of the slit t entering from the one surface side of the plate material P is connected in this way is alternately formed in the vertical direction on the front surface and the back surface, so that the plate material P is folded up and down in a zigzag shape. Or it can be moved up and down while developing {FIG. 1 (c)} in a planar shape. The slit t can also be expressed as a discontinuous portion described in the claims.

  Further, the plate material P is provided with a through hole Pb, and a lifting string 24 suspended from the head box 21 is linearly inserted into the through hole Pb. The through hole Pb is provided between the slits t of the plate material P. In this example, it is provided at the center position between the slits t. The lower end of the lifting / lowering string 24 is fixed to a bottom rail 25 attached to the lower end of the plate material P. As shown in FIG. 1 (a), the lifting / lowering string 24 that hangs down through the through hole Pb is disposed in parallel on both sides of the plate material P.

  As shown in FIG. 1C, the lifting / lowering string 24 can apply a vertical tension that pulls the head box 21 and the bottom rail 25 toward each other when the screen S is flattened. The tension is applied by operating the operation code 23.

  As the plate material P, plastic corrugated cardboard plates (pradans) P having various configurations as shown in FIGS. 2A to 2E and plate materials having a hollow structure are used. FIG. 2A shows a plate material (pradan) having a structure in which the intermediate material Pd of the honeycomb structure shown in FIG. 2B is fixed by being sandwiched between flat plates Pe and Pe. FIG. 2C shows a plate material (pradan) having a structure in which an elongated cylindrical medium material Pd is sandwiched and fixed between two flat plates Pe and Pe. FIG. 2D shows a plate material (pradan) having a structure partitioned by a partition plate Ph so that a rectangular tube-like cavity is formed between the upper and lower flat plates Pi, Pi separated from each other. FIG. 2 (e) shows a plate material (pradan) having a structure in which an intermediate material Pj having a corrugated structure is sandwiched and fixed between flat plates Pk and Pk. In this plate material, slits are inserted in a direction orthogonal to the drawing from the front surface side or the back surface side of the flat plate Pk while the intermediate material Pj and the flat plate Pk are joined. In addition to the platen, the plate material P may be a plate material having various configurations similar to those shown in FIGS. 2A to 2D using other materials.

  The operation cord 23 shown in FIG. 1 is connected to the lifting string 24 through a cord outlet of the head box 21 via a cord equalizer (not shown). By operating the operation cord 23 and changing the amount of the lifting / lowering string 24 pulled out from the cord outlet, the bottom rail 25 is moved up and down, and the screen S is moved up and down.

<Operation of First Embodiment>
When the operation code 23 shown in FIG. 1 is pulled, the pull-out amount of the lifting / lowering string 24 is changed simultaneously, the bottom rail 25 is pulled up, and the screen S is raised while being folded in a zigzag manner. Finally, it is mounted on the lower surface of the head box 21 in a folded state with no gap. When the operation cord 23 is pulled out from this state and then released, a stopper (not shown) in the head box 21 is actuated to hold the lifting / lowering string 24 and the lowering of the bottom rail 25 due to its own weight is prevented. When the operation cord 23 is pulled a little again, the stopper releases the lifting string 24 and lowers the bottom rail 25. As the screen descends, the screen S is developed while descending, and finally, the screen S is developed into a single flat plate as shown in FIG. At this time, the upper and lower surfaces of each slit t abut and the entire screen S is held in a single plate shape.

<Effects of First Embodiment>
The pleated screen 20 of the first embodiment has a screen S that can be folded in a zigzag shape, and has the following characteristic configuration.
(1) The screen S has a slit t crossing between both ends of the platen P on both surfaces of a plate member P (for example, a prada P) having a hollow structure and a surface at a predetermined interval in a direction (vertical direction) perpendicular to the slit t. They are formed alternately on the back surface.

  According to this configuration, since the slits t are formed alternately on both sides in the vertical direction of the prada P, the prada P is folded at the slit t position. In the state in which the platen P is expanded and the screen is extended, the screen S is formed of a plate material P such as a platen having a hollow structure, and thus has an air layer having a heat insulating effect. For this reason, when the screen S is developed in a planar shape, for example, a partition layer is formed by the screen S having an air layer between the window and the room, so that a heat insulating effect that blocks heat exchanged between the window and the outside is obtained. Can do. Moreover, the pleat screen 20 can be easily manufactured by a simple method of cutting the flat platen P alternately on the front and back sides.

  (2) The Pradan P that can be folded in a zigzag shape is configured to be planar when unfolded.

  According to this configuration, in the state in which the pladan P is expanded and the screen S is extended, the respective slit t portions come into contact with each other, and the entire screen S becomes flat. In this state, for example, there is no gap between the window and the heat insulating effect can be maintained.

  (3) The head box 21 disposed at the upper end of the screen S, the bottom rail 25 disposed at the lower end of the screen S, and at least one lifting string 24 having both ends fixed to the head box 21 and the bottom rail 25. With. In the screen S, a through hole 22b is formed in a pladan portion that is folded zigzag, and a lifting string 24 is inserted into the through hole 22b. The lifting / lowering string 24 is configured to be able to apply a tension that pulls the head box 21 and the bottom rail 25 in the opposing direction when the screen S is flattened.

  According to this configuration, the lifting string 24 inserted into the through hole 22b provides a tension for pulling the head box 21 and the bottom rail 25 in the opposite direction when the screen S is flattened. Due to this tension, a pressing force is exerted on the single flat screen S in the opposing direction from above and below, so that the vertical contact surfaces of the slits t of the screen S are pressed in the opposing direction with a stronger force. For this reason, the pressing strength against the pressing force from the one surface side of the screen S can be further increased.

<Application Example 1 of First Embodiment>
FIG. 3 is a side view showing the configuration of the pleated screen according to the application example 1 of the first embodiment.
The pleat screen 20A of the application example 1 shown in FIG. 3 is different from the pleat screen 20 (FIG. 1) of the first embodiment in that the screen S1 is configured as follows. That is, a plurality of Pradans P1 arranged in a rectangular shape with their end faces in the longitudinal direction in contact with each other are bonded to each other with a connecting tape 27 alternately between the front and back surfaces of each pair of adjacent Pradans P. In other words, it can be folded in a zigzag shape.

  Also in this configuration, the same slit-shaped portion t1 as the slit t {see FIG. 1 (b)} is formed at the boundary of the surface opposite to the boundary bonded with the connecting tape 27 of the screen S1. The slit-shaped portions t1 are alternately formed at predetermined intervals in the vertical direction on the front surface and the back surface of the screen S1.

Therefore, the pleated screen 20A of the application example 1 can achieve the same effects as the pleated screen 20 of the first embodiment.
Further, the screen S1 is configured by bonding the boundaries of the plurality of pradans P1 with the connecting tape 27 as described above. For this reason, if the connection tape 27 with high durability is used, when the operation of folding the screen S1 in a zigzag manner is repeated, durability against the consumption of the folding operation can be increased.

<Application Example 2 of First Embodiment>
FIG. 4 is a side view showing the configuration of the pleated screen according to the application example 2 of the first embodiment.
The pleated screen 20B of the application example 2 shown in FIG. 4 is different from the pleated screen 20 (FIG. 1) of the first embodiment in that the screen S2 is formed as follows. That is, slits t crossing between both ends are formed on both surfaces of a plate member (pradan) P having a hollow structure alternately on the front surface and the back surface at predetermined intervals in the vertical direction, and on the ridge line on the backside of the back surface folded by the slit t. The rib (reinforcing part) 28 straddling both lateral ends is provided. The rib 28 is configured separately from the plate material P, and is fixed to the plate material P by engagement or an adhesive. This rib 28 is attached to the ridgeline on the mountain folding side, and the plate P is movably attached from the folded state to the folded state from the folded state to the folded state from the folded state. Further, the screen S2 is configured by forming a through hole 28a penetrating in the vertical direction (rib array direction) in the rib 28 and inserting the lifting / lowering string 24 linearly into the through hole 28a.

  In this configuration, when the screen S2 is developed in a planar shape, a plurality of ribs 28 provided between both ends in the horizontal direction are provided for every other slit t in the vertical direction. At the slit boundary of the provided portion, it is possible to obtain a pressing strength that resists the pressing force from the surface on which the rib 28 is disposed. In addition, since the plurality of ribs 28 are regulated in the vertical direction by the lifting / lowering string 24 inserted through the through hole 28a at the time of flat development, the shake of the entire screen S2 can be reduced. Furthermore, since the through hole Pb (see FIG. 1) for passing the lifting / lowering string 24 through the screen S2 is unnecessary, light leakage is eliminated. Furthermore, since the lifting / lowering string 24 is disposed on the back surface side of the screen S2 and is not visible from the front surface side, the design can be improved.

Alternatingly formed, slits t1 and t1 are formed at the upper and lower positions on the front surface side with the slit t on the back surface side as the center. Next, a section between the slit t on the back surface side and the two slits t1 and t1 on the front surface side is regarded as a valley fold when viewed from the front surface side, and this valley fold side portion is projected to a predetermined length on the back side. . A rib (reinforcing portion) 29 is formed by bonding the protruding sections having a predetermined length in a state where they overlap each other. In other words, the rib 29 has a shape in which the Pradan P2 has a predetermined length and is overlapped on top and bottom. Further, the screen S3 is configured by forming a through hole 29a penetrating in the vertical direction (rib array direction) in the rib 29 and inserting the lifting string 24 linearly into the through hole 29a.

  In this configuration, when the screen S3 is flattened, a plurality of ribs 29 provided between the lateral ends are provided for every other slit boundary in the vertical direction (vertical direction). At the boundary of the portion where the rib 29 is disposed, a pressing strength against the pressing force from the surface where the rib 29 is disposed can be obtained. Furthermore, since the plurality of ribs 29 are regulated in the vertical direction by the lifting / lowering string 24 inserted through the through-hole 29a at the time of flat development, the lateral shake is suppressed and the overall shake of the screen S3 is reduced. be able to. In addition, the screen S3 can be easily manufactured by a simple method in which a single platen is cut alternately on the front and back sides.
