Hereinafter, various embodiments of the present invention will be described with reference to the drawings. The various embodiments shown below can be combined with each other.

1. First embodiment

1 and 2 are a front view and a left side view showing the overall configuration of the solar radiation shielding apparatus 1 according to the first embodiment of the present invention.

One end of the insolation shielding material 5 is attached to the upper beam 3, and the other end of the insolation shielding material 5 is attached to the lower beam 7, wherein the lower beam 7 is provided with an opening on one surface thereof. The method of attaching the insolation shielding material 5 to the upper beam 3 and the lower beam 7 is not particularly limited. In the present embodiment, the fabric pressing plate 9 is attached to both ends of the insolation shielding material 5, and the upper beam 3 and the lower beam are attached. Set on 7 The fabric pressing plate 9 is elastically mounted on the upper beam 3 and the lower beam 7 in such a manner that the opening portion is closed, thereby attaching the insolation shielding material 5 to the upper beam 3 and the lower beam 7.

The type of the solar radiation shielding material 5 is not limited. In the present embodiment, the solar radiation shielding material 5 is a pleated blind that can be bent in the vertical direction. The solar shading material 5 may also be a pull-up curtain or a louver or the like.

The lifting cord 11 is suspended from the upper beam 3 and inserted into the through hole 13 provided in the insolation shielding material 5, and suspended to support the lower beam 7. The lifting device changes the length of the lifting cord between the upper beam 3 and the lower beam 7 from the side of the upper beam 3, thereby causing the lower beam 7 to ascend or descend. The structure of the lifting device is not particularly limited. In the present embodiment, the lifting device includes an operating cord 15 that is connected to the lifting cord 11 via the balancer 14. By pulling the operating cord 15, the lifting cord 11 is pulled out from the upper beam 3, so that the length of the lifting cord between the upper beam 3 and the lower beam 7 is shortened, whereby the lower beam 7 is raised. When the force applied to the operating rope 15 is reduced, the lifting rope 11 is pulled into the upper beam 3 to lower the lower beam 7, but is blocked by the locking action of the stopper 17 provided in the upper beam 3. The lower beam 7 is lowered. The locking of the stopper 17 is released by pulling the operating cord 15 again, and then, when the force applied to the operating cord 15 is reduced, the lifting cord 11 is pulled into the upper beam 3, thereby lowering the lower beam 7.

As the lower beam 7 descends and the balancer 14 gradually approaches the upper beam 3, since the balancer 14 cannot pass through the rope exit 19 provided on the upper beam 3, at the position where the balancer 14 abuts the upper beam 3 The lower beam 7 stops descending, which is the lower limit position of the lower beam 7.

In addition, in the lifting device of the present embodiment, the transmission is balanced The device 14 abuts against the upper beam 3 to determine the lower limit position of the lower beam 7, but depending on the structure of the lifting device, various methods can be used to determine the lower limit position of the lower beam 7. For example, in the ninth embodiment of the Japanese Patent Laid-Open No. 2011-236555, the pulley is rotated by the bead chain, and the lifting rope is wound around the reel in the upper beam by the rotation of the pulley, thereby changing the upper beam. The length of the lifting cord between the lower beam, thereby raising or lowering the lower beam, and, in this embodiment, the connector of the ball having a larger diameter than the bead chain is used to join the ends of the non-circular bead chain, and The lower limit position of the lower beam 7 is determined by the fact that the connector cannot pass between the pulley and the pulley box. Further, the lower limit position of the lower beam 7 may be determined by another mechanism that stops the rotation of the spool when the lower beam 7 is lowered to the predetermined position.

In the scope of the patent application, the various devices for determining the lower limit position of the lower beam 7 are referred to as "restricting devices".

On the side of the lower beam 7, the lifting cord 11 is passed through the through hole formed in the fabric pressing plate 9, and is held by the adjusting device 21 disposed in the lower beam 7.

Hereinafter, the adjustment device 21 will be described in detail with reference to FIGS. 3 to 6 .

As shown in FIGS. 3 to 4, the adjustment device 21 includes a holding member 23 that holds the lifting/lowering cord 11, a rotating member 25 that is rotatably attached to the holding member 23, and a rotating member that rotates the rotating member 25. The operation portion 27 is rotated, and the adjustment device 21 has a function of changing the introduction amount of the lift cord 11 into the lower beam 7 as the rotation of the rotary member 25, thereby adjusting the lower limit position of the lower beam 7.

As shown in Figures 5(a) to (f), the entire holding member 23 The first cord receiving groove 33 is provided in the long range, and the lifting cord 11 is housed in the first string receiving groove 33. The front end of the lifting cord 11 is provided with a locking portion 31 (deduction of the lifting cord 11), and the transmission locking portion 31 abuts against the peripheral wall of the first cord housing groove 33 to prevent the lifting cord 11 from being directed in the direction of the arrow A in FIG. Was extracted. Further, since the first string accommodation groove 33 faces the bottom side of the lower beam 7, the lift cord 11 is held between the holding member 23 and the lower beam 7 in the first string accommodation groove 33.

Further, in the present embodiment, the guide rail 29 is provided at the center in the width direction of the bottom portion of the lower beam 7, and the guide member is provided at a position closer to the lower beam 7 side than the first rope receiving groove 33 of the holding member 23. Slot 35. The rail holding groove 35 communicates with the first string receiving groove 33 and extends in parallel with the first string receiving groove 33. The holding member 23 is attached to the guide rail 29 by inserting the guide rail 29 into the rail holding groove 35. With this configuration, in the present embodiment, the lift cord 11 is held in a space surrounded by the peripheral wall of the first cord storage groove 33 and the guide rail 29 (see FIG. 4(b)).

The holding member 23 is provided with a fitting hole 37 fitted to the rotating member 25 at a position where the first string receiving groove 33 is blocked (for example, a central position in the longitudinal direction of the first string receiving groove 33), and the rotating member 25 is Inserted in the fitting hole 37, the rotating member 25 is attached to the holding member 23 in a relatively rotatable manner.

As shown in FIGS. 6(a) to 6(d), the rotating member 25 includes a base portion 39, a distal end portion 41 extending from the base portion 39, and a radially outward projection from the base portion 39 (in other words, the radius is larger than The flange portion 42 of the base portion 39). The tip end portion 41 is provided with a claw portion 43 that protrudes outward in the radial direction, and when the rotating member 25 is inserted into the fitting hole 37, the claw portion 43 and the holding member The upper surface of the 23 is engaged to prevent the rotating member 25 from coming off the holding member 23.

The top end portion 41 is provided with a second rope receiving groove 45 through which the lifting cord 11 passes. In a state in which the rotating member 25 is fitted into the holding member 23, the second string receiving groove 45 is disposed on a straight line connecting the pair of first string receiving grooves 33 blocked by the fitting hole 37, and the lifting rope 11 is lifted from the lifting rope Pass through position 47 (refer to Fig. 6(b)). In addition, when the rotation member 25 is inserted into the fitting hole 37 of the holding member 23, the fitting piece can be easily oriented radially inward by the second string receiving groove 45, and the distal end portion 41 is formed into a bifurcated fitting piece. Elastic deformation. Therefore, the rotating member 25 can be easily fitted to the holding member 23.

As shown in FIG. 3, when the rotating member 25 is fitted in the holding member 23 and the rotating cord 11 is housed in the first and second string receiving grooves 33, 45, the rotating member 25 is rotated. It is wound around the lifting cord winding position 49 of the distal end portion 41 of the rotating member 25 (see FIG. 6(b)). Then, the lifting cord 11 is introduced into the lower beam 7 by winding, so that the lower limit position of the lower beam 7 is raised. Therefore, the lower limit position of the lower beam 7 can be adjusted by the rotation of the rotating member 25.

A rotation operation portion 27 is provided on the outer surface side of the base portion 39 of the rotating member 25, and the rotation member 25 is rotated by the rotation operation portion 27. In the present embodiment, the rotation operation portion 27 is a linear groove (that is, a "-" (subtracted) shape) engagement groove. However, the configuration of the rotation operation portion 27 is not particularly limited, and may be "+" ( The engagement groove of another shape such as a shape or a hexagonal shape may be an engagement protrusion of a shape, a + shape, or a hexagonal shape.

When the rotary operation portion 27 is an engagement groove, the transmission is made to be a snail The tip end of the rotating jig such as a wire cutter or a hard metal piece, a cross-shaped screwdriver, or a hexagonal wrench is engaged in the engagement groove, and the rotation jig is rotated in this state, whereby the rotating member 25 can be rotated. When the rotation operation portion 27 is the engagement convex portion, the rotation jig that engages with the engagement convex portion is prepared, and the rotation member 25 can be rotated by the same operation. Further, it is also possible to simply increase the amount of protrusion of the base portion 39 from the lower beam 7, and grasp the side surface of the protruding portion to rotate the rotating member 25. In this case, the side surface of the protruding portion serves as the rotation operation portion 27.

A through hole 51 (see FIG. 7(a)) is provided at a position (ie, a bottom portion) of the lower beam 7 where the holding member 23 is provided. The rotating member 25 passes through the through hole 51 and is inserted into the lower beam 7. Since the through hole 51 has a size slightly smaller than the flange portion 42 and the base portion 39 of the rotating member 25 can be inserted therein, when the rotating member 25 is pushed into the through hole 51, the flange portion 42 and the bottom surface of the lower beam 7 are provided. In addition, the upper surface 56 and the shoulder portion 59 of the base portion 39 are also in contact with the two abutting portions 61 provided in the fitting hole 37, so that the rotating member 25 can be prevented from being excessively pushed into the through hole 51. At this time, since the claw portion 43 is engaged with the upper surface of the holding member 23 (see FIG. 4( c )), it is possible to prevent the rotating member 25 from coming off the through hole 51 . Further, the holding member 23 is slidable along the guide rail 29 before being inserted into the rotating member 25, but its position is fixed after being fitted to the rotating member 25.

Further, in the present embodiment, the through hole 51 is completely blocked by the flange portion 42, and an accident such as a hand that cuts the edge of the through hole 51 can be prevented, thereby improving safety. However, the flange portion 42 is not The necessary member may be formed such that the entire rotating member 25 is housed in the lower beam 7, and the rotating jig is inserted into the through hole 51 and the rotating operation portion 27 is provided. Engage, thereby rotating the rotating member 25.

Further, in the present embodiment, the rotation operation portion 27 is provided on the bottom surface side of the lower beam 7. However, for example, a through hole may be formed in the fabric pressing plate 9, and the rotation jig may be inserted into the through hole and rotated. The distal end portion 41 of the member 25 is engaged with each other, and the rotating member 25 is rotated or the distal end portion 41 is protruded outward through the through hole, and the distal end portion 41 is grasped to rotate the rotating member 25. Further, the rotating member 25 and the holding member 23 may be configured to be inserted into the rotating member 25 from the side of the fabric pressing plate 9.

Since the tension is always applied to the lift cord 11 by the weight of the lower beam 7, and the rotating member 25 winds the lift cord 11 against the tension, the lift cord is not provided if the mechanism is maintained after the winding. 11 will immediately unwind. Therefore, in the present embodiment, the rotating member 25 and the holding member 23 are engaged at a plurality of positions in the circumferential direction, whereby the lifting and lowering of the lifting cord 11 is prevented by the engagement.

Specifically, as shown in FIG. 5( c ), three holding recesses 53 are provided on the holding member 23 at intervals of 45 degrees on both sides of the first cord housing groove 33 . Further, four engagement convex portions 55 are provided at intervals of 90 degrees on the outer circumference of the base portion 39 of the rotary member 25. In the first state in which the engaging recess 53 and the engaging convex portion 55 are engaged, the two engaging convex portions 55 are located at the position of the first string receiving groove 33, and the remaining two engaging convex portions 55 are disposed at the first position. The center engagement recesses 53 of the three engagement recesses 53 on both sides of the string accommodation groove 33 are engaged.

When the rotating member 25 is rotated in this state, the engagement is released, and when the rotating member 25 is further rotated, the four engaging convex portions 55 are engaged with the four engaging recesses that are not engaged in the first state. 53 snaps. When you go one more When the step rotates the rotating member 25, it is again in the same state as the first state. Thereby, when the rotary member 25 is rotated by 45 degrees, the engaging recessed portion 53 and the engaging convex portion 55 are engaged at a plurality of positions, thereby preventing the lift cord 11 from being unwound. Further, the positions and the number of the engagement concave portions 53 and the engagement convex portions 55 may be appropriately changed, or the concave portions and the convex portions may be exchanged with each other.

If the holding member 23 is freely rotatable, when the rotating member 25 is rotated, since the engaging recessed portion 53 is engaged with the engaging convex portion 55, the rotation of the rotating member 25 is also transmitted to the holding member 23, thereby causing the holding member 23 Also rotate. In order to prevent the holding member 23 from rotating, the holding member 23 is preferably provided on the lower beam 7 so as to be rotatable about the rotation axis of the rotating member 25 or rotatable around the rotation axis of the rotating member 25 at 90 degrees or less.

Although the holding member 23 is preferably not rotatable, even if the holding member 23 is rotated together when the rotating member 25 is rotated, there is no problem as long as the rotatable angle thereof is 90 degrees or less. Since the lifting cord 11 can be wound as long as the rotating member 25 is further rotated. Further, the rotatable angle refers to an angle at which the rotating member 25 is rotated in one direction until the holding member 23 is not rotatable, and then the holding member 23 is not rotatable when the rotating member 25 is rotated in the reverse direction from this state.

Next, a method of assembling the adjustment device 21 of the present embodiment will be described with reference to FIGS. 7(a) to 7(f).

The width of the space between the guide rails 54 on the both side faces of the inner side of the lower beam 7 is preferably a width in which the holding member 23 can slide but cannot rotate, but as long as the holding member 23 can rotate about the rotation axis of the rotating member 25 The angle may be 90 degrees or less, and therefore, it may be a width that allows the holding member 23 to rotate within an angle of 90 degrees or less.

The second embodiment differs from the first embodiment only in the structure for sliding the holding member 23, and the adjusting device 21 can be assembled by the same method as the first embodiment.

Further, in the second embodiment, it is not necessary to provide the rail holding groove 35 in the holding member 23, but in order to make the member versatile, the holding member 23 provided with the rail holding groove 35 may be used.

3. Third embodiment

Next, a third embodiment of the present invention will be described with reference to Figs. 10 to 13 .

The structure of this embodiment is similar to that of the first embodiment, and mainly differs in the structure of the holding member 23 shown in Figs. 12(a) to (f). In the first embodiment, the first string receiving groove 33 of the holding member 23 is opened toward the bottom side of the lower beam 7, but in the present embodiment, the first string receiving groove 33 faces the opening side of the lower beam 7 (the fabric pressing plate 9) The mounting side) is opened, and the lifting cord 11 is housed in the first cord receiving groove 33 from the opening side. Locking protrusions 57 are provided on the inner side walls of both sides of the first cord receiving groove 33 to prevent being received in the first The lifting cord 11 in the rope receiving groove 33 is detached.

In this embodiment, the structure of the rotating member 25 shown in Figs. 13(a) to (d) is similar to that of the first embodiment, but there are several differences.

The hole 37 coincides with the position of the through hole 51 in the lower beam 7.

Next, as shown in FIG. 14(c), the rotating member 25 is inserted into the fitting hole 37 through the through hole 51, and the holding member 23 is fitted into the rotating member 25.

Next, as shown in FIG. 14(d), the lift cord 11 is press-fitted into the first cord storage groove 33 of the holding member 23 from the opening side of the lower beam 7. Before or after this step, the locking portion 31 is formed at the end of the lifting cord 11 in advance.

After the above steps, the adjustment device 21 is assembled. Therefore, according to the method of the present embodiment, the assembly can be completed only by fitting the holding member 23 to the rotating member 25 and pressing the lifting/lowering cord 11 into the first cord housing groove 33, which makes assembly very easy.

Further, the configuration of the present embodiment can also be applied to a configuration in which a guide rail 54 is provided on a side surface inside the lower beam 7 as in the second embodiment, and a structure in which the lower beam 7 and the holding member 23 are fitted by an elastic fitting structure is used. .

4. Fourth embodiment

Next, a fourth embodiment of the present invention will be described with reference to Figs. 15 and 16 .

The structure of the present embodiment is similar to that of the third embodiment, and mainly differs in the structure of the holding member 23. In the third embodiment, the first string accommodation groove 33 is opened toward the opening side of the lower beam 7 and extends from the fitting hole 37 toward both sides in the longitudinal direction. However, in the present embodiment, the first rope accommodation Similarly to the first embodiment, the groove 33 is opened toward the bottom side of the lower beam 7 and extends only toward one side of the fitting hole 37.

The assembling method of the adjusting device 21 of the present embodiment is similar to that of the first embodiment. In the first embodiment, as shown in FIGS. 7(a) and (b), after the lifting cord 11 is inserted into the through hole 51, The holding member 23 is slid to be in the state of FIG. 7(c). However, in the present embodiment, as shown in FIG. 14(b), the through hole of the holding member 37 and the lower beam 7 is formed. In a state where the positions of 51 are the same, the lift cord 11 is inserted into the fitting hole 37 and the through hole 51, and then the holding member 23 is further slid to be in the state shown in Fig. 7(c). The subsequent steps are the same as those of the first embodiment, and finally the structure shown in Fig. 15 is obtained.

In the present embodiment, the lift cord 11 extends through the fitting hole 37 toward the outside of the lower beam 7. Even in such a configuration, when the rotary member 25 is rotated, the claw portion 43 is engaged with the lift cord 11, and the lift cord 11 can be wound around the distal end portion 41 of the rotary member 25, whereby the lower beam can be adjusted. The lower limit position of 7.

5. Fifth embodiment

Next, a fifth embodiment of the present invention will be described with reference to Figs. 17 to 18 .

In the first to fourth embodiments, the lifting/lowering cord 11 is wound around the lifting cord winding position 49 (see 6(b)) of the distal end portion 41 of the rotating member 25 by the rotation of the rotating member 25, However, in the present embodiment, the lift cord 11 is wound around the tubular portion 36 of the holding member 23 by the rotation of the first rotating member 25a and the second rotating member 25b.

Figure 17 shows the lower beam 7 and the disassembled adjustment device 21. Figure 18 shows the assembled adjustment device 21. The adjusting device 21 is composed of three members of the holding member 23, the first rotating member 25a, and the second rotating member 25b. Similarly to the second embodiment, the holding member 23 is engaged with the guide rails 54 provided on the both side surfaces of the inner side of the lower beam 7.

The assembling method of the adjusting device 21 is as follows: First, the lifting cord 11 is inserted into the first cord housing groove 33 and the upper opening portion 34 that communicates therewith. In this state, the fitting hole 37 of the holding member 23 is aligned with the position of the through hole 51 in the lower beam 7.

Next, the second rotating member 25b is pressed against the tubular portion 36 which is raised from the base portion 26 of the holding member 23 in a state where the lifting cord 11 is engaged in the engaging groove 46 provided in the second rotating member 25b. On the upper surface, in this state, the first rotating member 25a is inserted into the fitting hole 37 of the holding member 23 and the fitting hole 63 of the second rotating member 25b through the through hole 51, and the claw portion 43 and the second portion are provided. The upper surface of the rotating member 25b is engaged, thereby completing the assembly of the adjusting device 21.

The cross-sectional shape of the fitting hole 63 of the second rotating member 25b and the cross-sectional shape of the tip end of the first rotating member 25a each have a shape in which the outer edge of the circle is cut, whereby the tip end of the first rotating member 25a is embedded. When the fitting hole 63 is engaged, the first rotating member 25a rotates together with the second rotating member 25b. Further, when the rotation angle of the first rotating member 25a is adjusted so that the distal end of the first rotating member 25a is engaged with the fitting hole 63, the direction of the engaging groove 46 and the direction of the second string receiving groove 45 naturally become the same. Thereby, the lifting cord 11 is housed in the second cord housing groove 45.

A flange portion 42 is provided on the proximal end side of the first rotating member 25a. The flange portion 42 is sized so as not to enter the through hole 51, whereby the flange portion 42 abuts against the bottom surface of the lower beam 7, thereby preventing the first rotating member 25a from being excessively pushed into the lower beam 7. The rotation operation portion 27 is provided on the bottom surface of the first rotating member 25a, and the first rotating member 25a can be rotated by operating the rotation operation portion 27.

When the first rotating member 25a rotates, the second rotating member 25b also rotates together, and the lifting/lowering cord 11 in the engaging groove 46 of the second rotating member 25b is wound around the tubular portion 36. Thereby, the length of the lifting cord 11 introduced into the lower beam 7 is changed, so that the lower limit position of the lower beam 7 can be adjusted.

6. Sixth embodiment

In the first to fifth embodiments, the lifting cord 11 is inserted through the through hole of the fabric pressing plate 9 attached to the opening of the lower beam 7, and then inserted into the lower beam 7 as an example, but as shown in Fig. 19 As shown, the lifting cord 11 can also be inserted into the lower beam 7 through a through hole provided in the surface 7a, wherein the surface 7a corresponds to the short side of the lower beam 7 having a substantially rectangular cross section (this structure is applicable) In the pleated curtain of the type disclosed in Japanese Patent Laid-Open No. 2008-266979, for example. In this case, a through hole is provided in the surface 7b corresponding to the long side of the lower beam 7 having a substantially rectangular cross section, and the rotating member 25 is inserted through the through hole and fitted into the holding member 23, and is rotated in the direction of the arrow X. The operation unit 27 rotates the rotating member 25 to wind the lift cord 11, whereby the lower limit position of the lower beam 7 can be adjusted.

7. Other implementations

In the first to fifth embodiments, the holding member 23 is caused along The guide rail 29 or the guide rail 54 provided on the lower beam 7 slides, but the holding member 23 does not necessarily have to be slid. For example, the holding member 23 may be elastically engaged with the lower beam 7. Further, an engagement structure may not be provided between the holding member 23 and the lower beam 7. For example, in the first embodiment, since the holding member 23 and the lower beam 7 are fixed to be relatively rotatable by the claw portion 43 and the flange portion 42 of the rotating member 25, therefore, only the rotation of the holding member 23 is provided. The mechanism with an angle below 90 degrees can be used. In this case, the strength of the claw portion 43 and the flange portion 42 is such a degree that the force applied between the holding member 23 and the lower beam 7 can be maintained.

However, the lower beam 7 may be inclined toward the front-rear direction due to the shape of the lower beam 7 or the installation position of the adjustment device 21, etc., in order to suppress this, in FIG. 20, in the front-rear direction of the adjustment device 21 The center of the center is more biased toward the outdoor side, and a rope balancer 65 is attached to the fabric platen 9, so that the center of gravity position is moved to a higher position in the lower beam 7, thereby making the lower beam 7 less inclined.
