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

1. 1st Embodiment FIG.1 and FIG.2 is the front view and left view which show the whole structure of the solar radiation shielding apparatus 1 of 1st Embodiment of this invention.
One end of the solar shading material 5 is attached to the head box 3, and the other end of the solar shading material 5 is attached to the bottom rail 7 having an opening on one surface. A method for attaching the solar shading material 5 to the head box 3 and the bottom rail 7 is not particularly limited. In this embodiment, the fabric presser 9 is attached to both ends of the solar shading material 5, and the fabric presser 9 is attached to the headbox 3. The solar shading material 5 is attached to the head box 3 and the bottom rail 7 by elastically attaching the head box 3 and the bottom rail 7 so as to block the opening provided in the bottom rail 7.

The type of the solar shading material 5 is not limited, but in the present embodiment, it is a pleated screen that can be bent in a zigzag shape in the vertical direction. The solar shading material 5 may be a raised curtain or a blind.

The lifting / lowering cord 11 is suspended from the head box 3 and inserted into a through hole 13 provided in the solar shading material 5 to suspend and support the bottom rail 7. The elevating means elevates the bottom rail 7 by changing the length of the elevating cord between the head box 3 and the bottom rail 7 from the head box 3 side. Although the structure of the raising / lowering means is not specifically limited, In this embodiment, the operation code 15 connected with the raising / lowering cord 11 via the equalizer 14 is provided. By pulling the operation cord 15, the lifting / lowering cord 11 is pulled out from the head box 3. As a result, the lifting / lowering cord length between the head box 3 and the bottom rail 7 is shortened, and the bottom rail 7 is raised. When the force applied to the operation cord 15 is loosened, the lifting / lowering cord 11 is pulled into the head box 3 and the bottom rail 7 tries to descend, but it is lowered by the locking action of the stopper device 17 provided in the head box 3. Is blocked. By pulling the operation cord 15 again, the lock of the stopper device 17 is released. Thereafter, when the force applied to the operation cord 15 is loosened, the lifting / lowering cord 11 is drawn into the head box 3 and the bottom rail 7 is lowered. As the bottom rail 7 descends, the equalizer 14 approaches the head box 3, and the equalizer 14 cannot pass through the cord outlet 19 provided in the head box 3, so that the equalizer 14 comes into contact with the head box 3. Lowering of the bottom rail 7 stops, and this position becomes the lower limit position of the bottom rail 7.

In the lifting / lowering means of this embodiment, the lower limit position of the bottom rail 7 is determined by the position where the equalizer 14 and the head box 3 abut. The lower limit position of the bottom rail 7 varies depending on the configuration of the lifting / lowering means. Determined by the method. For example, in the ninth embodiment of Japanese Patent Application Laid-Open No. 2011-236555, a pulley is rotated by a ball chain, and the lifting / lowering cord is wound around a winding shaft in the head box by rotating the pulley, thereby causing a gap between the head box and the bottom rail. The bottom rail is raised and lowered by changing the lifting / lowering cord length. In this embodiment, both ends of the non-looped ball chain are connected by a connector having a diameter larger than the ball of the ball chain. The lower limit position of the bottom rail 7 is determined using the fact that it cannot pass between the pulley and the pulley case. Further, the lower limit position of the bottom rail 7 may be determined by another mechanism that stops the rotation of the winding shaft when the bottom rail 7 is lowered to a predetermined position. Thus, various means for determining the lower limit position of the bottom rail 7 are referred to as “regulating means” in the claims.

The lifting / lowering cord 11 is held on the bottom rail 7 side by an adjusting device 21 disposed in the bottom rail 7 through a through hole formed in the fabric retainer 9.

Hereinafter, the details of the adjusting device 21 will be described with reference to FIGS.

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 attached to the holding member 23 so as to be relatively rotatable, and a rotation that rotates the rotating member 25. And an operation portion 27, and has a function of adjusting the lower limit position of the bottom rail 7 by changing the amount of pulling the lifting / lowering cord 11 into the bottom rail 7 as the rotating member 25 rotates. .

As shown in FIGS. 5A to 5F, the holding member 23 has a first cord housing groove 33 over its entire length, and the lifting / lowering cord 11 is placed in the first cord housing groove 33. Be contained. A locking portion 31 (knot of the lifting cord 11) is provided at the tip of the lifting / lowering cord 11, and the lifting / lowering cord 11 is in FIG. Is pulled out in the direction of arrow A. Further, since the first cord housing groove 33 faces the bottom rail 7 side, the lifting cord 11 is held between the holding member 23 and the bottom rail 7 in the first cord housing groove 33. In this embodiment, a rail 29 is provided at the center of the bottom rail 7 in the width direction, and the holding member 23 has a rail holding groove 35 on the bottom rail 7 side of the first cord receiving groove 33. is doing. The rail holding groove 35 communicates with the first cord housing groove 33 and extends parallel to the first cord housing groove 33. The holding member 23 is attached to the rail 29 by inserting the rail 29 into the rail holding groove 35. With this configuration, in this embodiment, the lifting / lowering cord 11 is held in a space surrounded by the peripheral wall of the first cord housing groove 33 and the rail 29 (see FIG. 4B).

The holding member 23 includes a fitting hole 37 that fits the rotating member 25 at a position where the first cord housing groove 33 is divided (for example, at the center of the first cord housing groove 33 in the longitudinal direction). The rotating member 25 is inserted into the fitting hole 37 and attached to the holding member 23 so as to be relatively rotatable.

As shown in FIGS. 6A to 6D, the rotary member 25 has a base 39, a tip 41 extending from the base 39, and a radial projection from the base 39 (in other words, a radius greater than the base 39). The flange portion 42 is provided. The distal end portion 41 is provided with a claw portion 43 that protrudes in the radial direction. When the rotation member 25 is inserted into the fitting hole 37, the claw portion 43 engages with the upper surface of the holding member 23, and the rotation member 25. Is prevented from being separated from the holding member 23. The distal end portion 41 is provided with a second cord housing groove 45 through which the lifting / lowering cord 11 passes. In a state where the rotating member 25 is fitted to the holding member 23, the second cord housing groove 45 is arranged on a straight line connecting the pair of first cord housing grooves 33 divided by the fitting hole 37, and is moved up and down. The lifting / lowering cord 11 passes through the cord threading position 47 (see FIG. 6B). Further, the distal end portion 41 is a bifurcated fitting piece by the second cord housing groove 45, and each fitting piece is inserted when the rotating member 25 is inserted into the fitting hole 37 of the holding member 23. It can be easily elastically deformed radially inward. For this reason, the rotation member 25 and the holding member 23 can be easily fitted.

As shown in FIG. 3, when the rotating member 25 is engaged with the holding member 23 and the rotating cord 25 is rotated in a state where the lifting / lowering cord 11 is housed in the first and second

cord housing grooves

33 and 45, The cord 11 is wound around the lifting / lowering cord winding position 49 of the distal end portion 41 of the rotating member 25 (see FIG. 6B). Then, the lifting / lowering cord 11 is pulled into the bottom rail 7 and the lower limit position of the bottom rail 7 is raised by the amount wound up. Therefore, the lower limit position of the bottom rail 7 can be adjusted by the rotation of the rotating member 25.

A rotation operation unit 27 is provided on the outer surface side of the base 39 of the rotation member 25, and the rotation member 25 is rotated by the rotation operation unit 27. In the present embodiment, the rotation operation unit 27 is a linear (that is, − (minus) shape) engagement groove, but the configuration of the rotation operation unit 27 is not particularly limited, and is a + (plus) shape, a hexagonal shape. The engaging groove may have another shape such as a negative shape, a negative shape, a positive shape, or a hexagonal shape. The rotating member 25 can be rotated by engaging the engaging groove with the tip of a rotating jig such as a minus driver, coin, plus driver, or hexagon wrench and rotating the rotating jig in this state. In the case of the engaging convex portion, a rotating jig that engages with the engaging convex portion is prepared, and the rotating member 25 can be rotated by the same operation. Alternatively, the amount of protrusion of the base portion 39 from the bottom rail 7 may be increased, and the rotating member 25 may be rotated by grasping the side surface of the protruding portion. In this case, the side surface of the protruding portion becomes the rotation operation unit 27.

The bottom rail 7 has a through hole 51 (see FIG. 7A) on the installation surface (that is, the bottom surface) of the holding member 23, and the rotating member 25 passes into the bottom rail 7 through the through hole 51. Inserted. Since the through hole 51 has a size that allows the base 39 of the rotating member 25 to be inserted and is slightly smaller than the flange portion 42, when the rotating member 25 is pushed into the through hole 51, the flange portion 42. Comes into contact with the bottom surface of the bottom rail 7, and the upper surface 56 and the shoulder 59 of the base portion 39 also come into contact with the two contact portions 61 provided in the fitting hole 37, thereby preventing further pressing. . At this time, since the claw portion 43 is engaged with the upper surface of the holding member 23 (see FIG. 4C), the rotation member 25 is prevented from coming out of the through hole 51. Before the rotating member 25 is inserted, the holding member 23 can freely slide along the rail 29, but its position is fixed by fitting with the rotating member 25. In the present embodiment, the through hole 51 is completely blocked by the flange portion 42 to prevent an accident such as a hand being cut at the edge of the through hole 51, and safety is improved. However, the flange portion 42 is essential. Instead, the entire holding member 23 is accommodated in the bottom rail 7, and a rotating jig 25 is inserted into the through hole 51 and engaged with the rotation operation unit 27 to rotate the rotating member 25. Also good. Furthermore, in the present embodiment, the rotation operation unit 27 is provided on the bottom surface side of the bottom rail 7. For example, a through hole is provided in the fabric retainer 9 and a rotating jig is inserted into the through hole to rotate the rotating member. The front end portion 41 may be engaged and rotated, or the front end portion 41 may be protruded to the outside through a through hole, and the front end portion 41 may be grasped and rotated. Moreover, you may comprise the rotation member 25 and the holding member 23 so that the rotation member 25 may be inserted from the dough presser 9 side.

Tension is always applied to the lifting / lowering cord 11 by the weight of the bottom rail 7, and the rotary member 25 winds the lifting / lowering cord 11 against this tension. Therefore, if there is no mechanism for holding the state after winding, the lifting / lowering cord 11 11 will be rewound immediately. Therefore, in the present embodiment, the rotating member 25 and the holding member 23 are engaged at a plurality of locations in the circumferential direction, and the rewinding of the lifting / lowering cord 11 is prevented by this engagement. Specifically, as shown in FIG. 5C, the holding member 23 is provided with three engagement recesses 53 on both sides of the first cord housing groove 33 at intervals of 45 degrees. The rotating member 25 is provided with four engaging convex portions 55 around the base portion 39 at intervals of 90 degrees. In the first state where the engagement recess 53 and the engagement protrusion 55 are engaged, the two engagement protrusions 55 are at the position of the first cord housing groove 33, and the remaining two engagement protrusions 55 are The three engaging recesses 53 provided on both sides of the first cord receiving groove 33 are engaged with the central one. When the rotating member 25 is rotated from this state, the engagement is released. When the rotating member 25 is further rotated, the four engaging convex portions 55 engage with the four engaging concave portions 53 that are not involved in the engagement in the first state. To do. When the rotating member 25 is further rotated, the same state as the first state is obtained again. As described above, the engagement concave portion 53 and the engagement convex portion 55 are engaged at a plurality of positions for every 45 degrees of rotation to prevent the lifting / lowering cord 11 from being unwound. In addition, the position and number of the engagement recessed part 53 and the engagement convex part 55 can be changed suitably, and you may replace a recessed part and a convex part.

When the holding member 23 is rotatable, when the rotating member 25 is rotated, the rotation of the rotating member 25 is also transmitted to the holding member 23 by the engagement of the engaging concave portion 53 and the engaging convex portion 55, thereby holding the holding member 23. The member 23 also rotates. In order to prevent this, the holding member 23 is preferably installed on the bottom rail 7 so as not to rotate around the rotation axis of the rotation member 25 or to have a rotatable angle within 90 degrees. Although it is preferable not to be able to rotate, even if the holding member 23 is rotated together when the rotating member 25 is rotated, it is not a big problem as long as it is within 90 degrees. This is because if the rotating member 25 is further rotated, the lifting / lowering cord 11 can be wound up. Note that the rotatable angle is determined by rotating the rotating member 25 in one direction to a position where the holding member 23 stops rotating, and then rotating the rotating member 25 in the opposite direction from that state until the holding member 23 stops rotating. Means angle.

Next, a method for assembling the adjustment device 21 of the present embodiment will be described with reference to FIGS.
First, as shown in FIG. 7A, the lifting / lowering cord 11 is inserted into the through hole 51 provided in the bottom rail 7. A locking portion (knot) 31 is formed at the end of the lifting / lowering cord 11.
Next, as shown in FIG. 7B, the holding member 23 is engaged with a rail 29 provided inside the bottom rail 7 (more specifically, from the end in the longitudinal direction of the bottom rail 7 to the rail 29. Is inserted into the rail holding groove 35 of the holding member 23), and the holding member 23 is slid on the rail 29 and moved to a position exceeding the through hole 51 as shown in FIG. By this operation, the lifting / lowering cord 11 is naturally accommodated in the first cord accommodating groove 33.
Next, as shown in FIG. 7 (d), the lifting / lowering cord 11 is pulled out from the through hole 51 from the inner surface side of the bottom rail 7.
Next, as shown in FIG. 7E, the holding member 23 is slid so that the position of the fitting hole 37 provided in the holding member 23 and the position of the through hole 51 of the bottom rail 7 coincide.
Next, as shown in FIG. 7 (f), the rotating member 25 is inserted from the outer surface side of the bottom rail 7 through the through hole 51 and fitted into the fitting hole 37 of the holding member 23, and the adjustment device 21 is assembled. Complete.
Thus, according to the configuration of the present embodiment, the adjustment device 21 is configured with only two parts, and the assembly thereof is very easy.

2. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. 8 and 9A to 9C. The configuration of the second embodiment of the present invention is similar to that of the first embodiment, but there is a difference in the structure of the bottom rail 7. In the first embodiment, the rail 29 is in the center in the width direction of the bottom rail 7 and the rail holding groove 35 of the holding member 23 is engaged with the rail 29. However, in this embodiment, the bottom rail 7 Rails 54 (see FIG. 8) are provided on both side surfaces, and the shoulder 24 (see FIG. 5 (a)) of the holding member 23 is engaged with the rails 54 (see FIG. 9 (b)). . As a result, the holding member 23 can be slid along the bottom rail 7 as in the first embodiment.

The width of the space between the rails 54 on both inner sides of the bottom rail 7 is preferably such that the holding member 23 is slidable and non-rotatable, but the holding member 23 is around the rotation axis of the rotating member 25. As long as the rotatable angle is within 90 degrees, it may be a width that allows such rotation.

The second embodiment is different from the first embodiment only in the configuration for enabling the holding member 23 to slide, and the adjusting device 21 can be assembled in the same manner as in the first embodiment.

In the second embodiment, the holding member 23 does not need the rail holding groove 35, but the holding member 23 having the rail holding groove 35 may be used for common parts.

3. Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIGS.
