[0017] 2. Details of the embodiment 2.1 [First embodiment of the present invention] A specific example of the first embodiment of the present invention will be described below with reference to the drawings. In the following description, components common to each embodiment will be given the same reference numerals, and repeated description will be omitted. It should be noted that the drawings are schematic, and the dimensional relationships and ratios of each element may differ from reality. The drawings may also include portions with different dimensional relationships and ratios.

[0018] FIG. 1 is a front view (A) and a side view (B) showing the overall configuration of a solar shading device including an operating tool support member and an operating tool support device according to a first embodiment of the present invention.

[0019] The sun shading device for which the operating tool support member of the present invention is used is a known sun shading device, and is not limited to a specific sun shading device, and can be applied to shading materials such as roman shades, pleated screens, shutters, etc. For example, the operating tool support member 10 of the present invention is applied to a sun shading device 100 that uses a screen 4, as shown in Fig. 1 .

[0020] As shown in FIG. 1, the solar shading device 100 is a cover that is fixed to, for example, a window frame or a wall around a window, and that allows the outside to be seen from inside the room, prevents the inside of the room from being seen from outside, and allows light and wind to enter the room, while preventing light and wind from entering the room.

[0021] In this embodiment, for ease of explanation, the left-right direction in which the set bar 1 of the solar shading device 100 extends is referred to as the longitudinal direction (arrow LR). The longitudinal direction (arrow LR) is also referred to as the left side (arrow L) and the right side (arrow R) in FIG. 1 as viewed from the indoor side. Furthermore, the direction in which the screen 4 hangs down or moves up and down relative to the set bar 1 is referred to as the up-down direction (arrow UD).

[0022] In addition, in the up-down direction (arrow UD), the side of the set bar 1 is the upper side (arrow U), and the side moving downward away from the set bar 1 is the lower side (arrow D). Furthermore, the direction intersecting the longitudinal direction (arrow LR) and the up-down direction (arrow UD) is the short side direction (front-to-back direction) indicated by arrow FB. In addition, in the short side direction (arrow FB), for example, the indoor side is the front side (arrow F), and the outdoor side is the rear side (arrow B). In addition, when the weight bar 30 is viewed from the short side direction (arrow FB) (side view), the direction going around the periphery of the weight bar 30 is the circumferential direction.

[0023] The solar shading device 100 according to this embodiment includes a screen 4 that blocks solar radiation, a roller pipe 3 that holds the screen 4, a weight bar 30 that applies tension to the screen 4, a side holder 2 that rotatably holds the roller pipe 3, a set bar 1 that fixes the position of the side holder 2, and an operating tool support device 50. The configuration of the solar shading device 100 will be described below.

[0024] The set bar 1 is attached to an attachment target such as a ceiling or wall of a building via a bracket (not shown). Side holders 2 are attached to both ends of the set bar 1 in the longitudinal direction (arrows LR). Hereinafter, the set bar 1 and side holders 2 will be collectively referred to as the "roller pipe holding portion."

[0025] In this embodiment, the set bar 1 is attached to the ceiling in the upward direction (arrow U) via a bracket. However, this is not limited to this, and the set bar 1 may also be attached to the wall in the backward direction (arrow B) via a bracket, as will be described later.

[0026] A cylindrical or approximately cylindrical roller pipe 3 is rotatably held between side holders 2 attached to both ends of the set bar 1 in the longitudinal direction (arrow LR). A screen 4 for blocking solar radiation is wrapped around the circumferential surface of the roller pipe 3 in the circumferential direction.

[0027] A weight bar 30 for applying tension to the screen 4 is attached to the downward end (arrow D) of the screen 4, and the lower end of the screen 4 is wrapped around the circumferential surface of the weight bar 30. The configuration of the weight bar 30 will be described later.

[0028] The operating tool support device 50 is attached to the lower end of the screen 4 so as to cover at least a part of the circumferential surface of the weight bar 30. The configuration of the operating tool support device 50 will be described later.

[0029] Next, the configurations of the operation tool support device 50 and the operation tool support member 10 will be described.

[0030] FIG. 2 is a side view showing the configuration of the operating tool support device according to the first embodiment of the present invention. FIG. 3 is a perspective view showing the configuration of the operating tool support device according to the first embodiment of the present invention. FIG. 4 is a perspective view showing the configuration of the operating tool support device according to the first embodiment of the present invention, and is a perspective view showing the configuration from an angle different from that of FIG. FIG. 5 is a side view showing the configuration of the operating tool support member according to the first embodiment of the present invention.

[0031] The operating tool support device 50 according to this embodiment includes an operating tool 20 used for winding and unwinding the screen 4, and an operating tool support member 10.

[0032] The operating tool support member 10 according to this embodiment includes a housing portion 11 for housing the weight bar 30, and a pressing tool 12 for fixing the weight bar 30 inside the housing portion 11. The housing portion 11 has a shape when the area for housing the weight bar 30 is viewed from the side (as viewed from the short side (arrow FB)), that is, a first tip portion 111 which is one end of the circumferential ends of the shape of the side surface of the housing portion 11, and a second tip portion 112 which is the other end of the first tip portion 111 of the circumferential ends of the area for housing the weight bar 30 and has an area for attaching the pressing tool 12. The configurations of the weight bar 30, the operating tool support device 50, and the operating tool support member 10 will be described below.

[0033] The operating tool support device 50 is used for winding and unwinding the screen 4 of the solar shading device 100. Specifically, when a user holds the operating tool 20 and pulls it downward (arrow D), the roller pipe 3 rotates clockwise in Fig. 1(B) and the screen 4 wound around the roller pipe 3 is unwound downward (arrow D), thereby performing a lowering operation.

[0034] On the other hand, a winding device (not shown) is built into the roller pipe 3, and by accumulating a certain amount of biasing force in a spring mechanism built into the winding device and then releasing the biasing force, the screen 4 wound around the roller pipe 3 is wound up upward (arrow U), and a lifting operation is performed. For example, when a user pulls the screen 4 slightly using the operating tool 20 and then releases the operating tool 20, the winding device releases the biasing force, and the screen 4 wound around the roller pipe 3 is wound up upward (arrow U), and a lifting operation is performed.

[0035] The operating tool support member 10 has a housing portion 11, a pressing tool 12, a protruding portion 13, a first hole portion 14, and a second hole portion 15.

[0036] The storage section 11 has a capacity large enough to accommodate the weight bar 30 with the lower end of the screen 4 wrapped around its periphery. The storage section 11 accommodates the weight bar 30 with the lower end of the screen 4 wrapped around it. The opening of the storage section 11 for accommodating the weight bar 30 is located on the front side (arrow F) in the short side direction (arrow FB).

[0037] 4 and 5, the accommodation section 11 has a first tip portion 111 which is one end of the circumferential ends of the side shape of the area that accommodates the weight bar 30, a second tip portion 112 which is the other end of the first tip portion 111 of the circumferential ends of the area that accommodates the weight bar 30 and is an area for attaching the pressing tool 12 having the rotation shaft 121, i.e., has a recess that receives the rotation shaft 121, a back portion 113, and a back arch portion 114. Specifically, with regard to the first tip portion 111 and the second tip portion 112, of the circumferential ends of the side shape of the area that accommodates the weight bar 30, the first tip portion 111 is on the front side (arrow F) and the second tip portion 112 is on the rear side (arrow B).

[0038] The rear portion 113 is located on the rear side (arrow B) of the storage portion 11, and has a shape such that when the weight bar 30 is fixed to the storage portion 11 by the pressing tool 12 in the short direction (arrow FB), the rear region 122 and the operating portion 125 of the pressing tool 12 are positioned more inward than the rear portion 113 of the storage portion 11.

[0039] The rear arch portion 114 is located forward (arrow F) of the rear portion 113 in the short direction (arrow FB), and is located below (arrow D) the rear portion 113 in the up-down direction (arrow UD). The rear arch portion 114 has a shape corresponding to the shape of a dimple portion 126 of the pressing tool 12, which will be described later.

[0040] The pressing tool 12 is connected to the second tip portion 112 via a rotation shaft 121, and can rotate around the rotation shaft 121 as a fulcrum. The weight bar 30 is sandwiched between the housing portion 11 and the pressing tool 12, thereby fixing the operating tool support member 10. A detailed method for fixing the weight bar 30 housed in the housing portion 11 will be described later.

[0041] The pressing tool 12 has a rotation axis 121 , a back surface area 122 , a first contact area 123 , a second contact area 124 , an operating portion 125 , and a dimple portion 126 .

[0042] The rotating shaft 121 has a diameter corresponding to the shape of the second tip portion 112, and is fitted onto the second tip portion 112. The pressing tool 12 can rotate around the rotating shaft 121 as a fulcrum.

[0043] When the weight bar 30 is fixed to the storage section 11 by the pressing device 12, the back region 122 is located on the rear side (arrow B) in the short direction (arrow FB) and has a shape that is located more inward than the back portion 113 of the storage section 11.

[0044] The first contact area 123 is an area that first comes into contact with the weight bar 30 housed in the housing portion 11 when the pressing tool 12 connected to the second tip portion 112 is rotated clockwise. The details will be described later.

[0045] The second contact area 124 is located between the first contact area 123 and the dimple portion 126, and is the area that will next come into contact with the weight bar 30 when the pressing tool 12 connected to the second tip portion 112 is rotated clockwise, after the first contact area 123 comes into contact with the weight bar 30 housed in the housing portion 11, and the pressing tool 12 is then rotated further. Details will be described later.

[0046] The operating portion 125 is a region formed continuously from the rear surface region 122, and is a region that the user grips when rotating the pressing tool 12. The dimple portion 126 is a region located between the second contact region 124 and the operating portion 125, and is located on the surface opposite to the rear surface region 122. The dimple portion 126 has a shape that corresponds to the shape of the rear arch portion 114.

[0047] The protrusion 13 is a region that protrudes toward the center of the storage section 11 in at least a portion of the storage section 11. Specifically, it has a shape that engages with an opening 31 of the weight bar 30, which will be described later. Therefore, the first tip 111 and the second tip 112 are not provided with claws for engaging with the weight bar 30.

[0048] As shown in FIG. 3, the storage section 11 has a first hole 14 and a second hole 15 as holes for connecting an operating tool 20 used for winding and unwinding the screen 4.

[0049] Specifically, the first hole 14 is provided so that a string-like support 21 connected to an operating tool 20 having a generally conical shape can be fitted into the operating tool support member 10. The support 21 inserted into the first hole 14 can be connected to the operating tool support member 10 and the operating tool 20 in the housing section 11, for example, by fastening it with a pin or tying it in a ball.

[0050] The second hole 15 is groove-shaped. Details of the second hole 15 will be described later.

[0051] The operating tool 20 has a generally conical shape, is held by a user, and is used to wind up and unwind the screen 4 in response to the user's operation. The shape and size of the operating tool 20 can be determined as desired.

[0052] The support 21 is attached to the upper side (arrow U) of the operating tool 20, and has a diameter that allows it to be inserted into the first hole 14. The length of the support 21 in the up-down direction (arrow UD) can be determined arbitrarily.

[0053] As shown in Fig. 2, the weight bar 30 is attached to the downward end (arrow D) of the screen 4, and applies tension to the screen 4. The cross section of the weight bar 30 is substantially H-shaped and substantially circular. As will be described later, the weight bar 30 is clamped between the housing portion 11 and the pressing tool 12, thereby fixing the operating tool support member 10.

[0054] The weight bar 30 has openings in both the up and down directions (arrows UD). The opening 31 on the downward side (arrow D) of the weight bar 30 is formed by folding back the end of the base material of the weight bar 30 on the downward side (arrow D) in the upward direction (arrow U). The size of the protrusion 13 in the short-side direction (arrow FB) is larger than the distance between the ends of the base material of the weight bar 30 on the downward side (arrow D) when folded back in the upward direction (arrow U). This is to ensure that the opening 31 is large enough for the weight bar 30 to engage with the protrusion 13. However, to prevent rattling when the weight bar 30 is housed in the housing 11, it is preferable that the size of the protrusion 13 in the short-side direction (arrow FB) be close to the distance between the ends of the base material of the weight bar 30 on the downward side (arrow D) when folded back in the upward direction (arrow U).

[0055] The weight bar 30 has a pressing area 32 that is pressed by a first contact area 123 and a second contact area 124 as the pressing tool 12 rotates around the rotation axis 121. The details will be described later.

[0056] Next, a method for fixing the weight bar 30 to the operating tool support member 10 will be described.

[0057] FIG. 6 is a side view (1 / 4) illustrating a method for fixing a weight bar to an operating tool support member according to the first embodiment of the present invention. FIG. 7 is a side view (2 / 4) illustrating a method for fixing a weight bar to an operating tool support member according to the first embodiment of the present invention. FIG. 8 is a side view (3 / 4) illustrating a method for fixing a weight bar to an operating tool support member according to the first embodiment of the present invention. FIG. 9 is a side view (4 / 4) illustrating a method for fixing a weight bar to an operating tool support member according to the first embodiment of the present invention.

[0058] It should be noted that the screen 4 is omitted from Figures 6 to 9 for the sake of explanation. In reality, the lower end of the screen 4 is wrapped around the circumferential surface of the weight bar 30, as shown in Figures 2 and 10.

[0059] 6, the operating part 125 is located at the rearmost side (arrow B) in the short-side direction (arrow FB), and the first contact area 123 is located at the bottommost side (arrow D) in the up-down direction (arrow UD). In this state, in the area of ​​the housing part 11 that houses the weight bar 30, there is no area of ​​the pressing tool 12 that protrudes further toward the center of the housing part 11 than the area that houses the weight bar 30 of the housing part 11.

[0060] Therefore, in the state shown in FIG. 6, it is possible to insert the weight bar 30 into the storage section 11 and to remove the weight bar 30 from the storage section 11.

[0061] 7, the protrusion 13 is engaged with the opening 31 of the weight bar 30, and the pressing tool 12 is then rotated clockwise. As a result, in the area of ​​the housing 11 that houses the weight bar 30, the first contact area 123 and a part of the second contact area 124 protrude further toward the center of the housing 11 than the area that houses the weight bar 30 of the housing 11.

[0062] Next, as shown in Fig. 8, the pressing tool 12 is rotated further clockwise than in Fig. 7. Then, the pressing area 32 of the weight bar 30 is pressed by the first contact area 123 of the pressing tool 12. The pressing area 32 is elastically deformed by being pressed by the first contact area 123. Specifically, the pressing area 32 is bent counterclockwise by being pressed by the first contact area 123.

[0063] Next, as shown in Figure 9, when the pressing tool 12 is rotated further clockwise than in Figure 8, the pressing area 32 and the first contact area 123 move away from each other, but instead the second contact area 124 comes into contact with the pressing area 32, and the pressing area 32 is pressed by the second contact area 124 of the pressing tool 12.

[0064] In this state, the weight bar 30 is held between the housing portion 11 and the pressing tool 12. Specifically, the weight bar 30 is held between the first tip portion 111 and the second contact area 124. Furthermore, the opening 31 of the weight bar 30 engages with the protrusion 13. These actions fix the operating tool support member 10.

[0065] At this time, when the weight bar 30 is fixed to the housing part 11 by the pressing tool 12, the rear region 122 of the pressing tool 12 is located inside the rear part 113 of the housing part 11. Specifically, the rear region 122 and the region of the operating part 125 located on the rear side (arrow B) of the outer periphery of the rear part 113 of the housing part 11 are located on the front side (arrow F).

[0066] In this embodiment, the protrusion 13 is engaged with the opening 31 of the weight bar 30, but the protrusion 13 may be omitted and the weight bar 30 may be inserted into the storage section 11.

[0067] In this case as well, the weight bar 30 is clamped between the housing portion 11 (particularly the first tip portion 111) and the pressing tool 12, thereby fixing the operating tool support member 10.

[0068] 9, at least a portion of the outer periphery of the weight bar 30 is located radially outward of a straight line 115 connecting the first tip 111 and the second tip 112 when the weight bar 30 is housed in the housing 11. Specifically, of the base materials of the weight bar 30 in the upward direction (arrow U), the outer periphery of the base material located on the first tip 111 side is at least partially located radially outward of the straight line 115 connecting the first tip 111 and the second tip 112.

[0069] 9, the first tip portion 111 contacts the lower region in the circumferential direction of the weight bar 30 via the screen 4. Specifically, the first tip portion 111 contacts the base material of the weight bar 30 in the downward direction (arrow D) via the screen 4, which is omitted for convenience of explanation.

[0070] 6 to 9, the pressing tool 12 comes into contact with the upper region in the circumferential direction of the weight bar 30 via the screen 4. Specifically, the pressing tool 12 comes into contact with the base material located on the second tip portion 112 side having the pressing region 32, among the base materials in the upper direction (arrow U) of the weight bar 30, via the screen 4, which is omitted for convenience of explanation.

[0071] More specifically, when the pressing tool 12 rotates clockwise, it first contacts in the first contact area 123 the base material located on the upper side (arrow U) of the weight bar 30, the base material located on the second tip end 112 side having the pressing area 32, via the screen 4, which is omitted for convenience of explanation.

[0072] When the pressing tool 12 is further rotated clockwise, the first contact area 123 separates from the part of the base material located on the second tip 112 side having the pressing area 32 among the parts of the base material located on the upper side (arrow U) of the weight bar 30. However, the pressing tool 12 comes into contact with the part of the base material located on the second tip 112 side having the pressing area 32 among the parts of the base material located on the upper side (arrow U) of the weight bar 30, in the second contact area 124, via the screen 4, which is omitted for convenience of explanation.

[0073] Next, the positional relationship between the set bar 1, the side holder 2, the roller pipe 3, and the screen 4 when the operating tool support device 50 is raised to the top will be described.

[0074] FIG. 10 is a side view showing the positional relationship when the operating tool support device according to the first embodiment of the present invention is raised to the uppermost position.

[0075] 10 shows a state in which the screen 4 is wound up by the roller pipe 3 that holds the screen 4, and the second tip 112 of the storage section 11 comes into contact with the roller pipe holding section that rotatably holds the roller pipe 3. At this time, the opening of the storage section 11 for storing the weight bar 30 is located on the front side (arrow F) in the short side direction (arrow FB), that is, in a position facing the roller pipe 3, so that the weight bar 30 stored in the storage section 11 comes into contact with the screen 4 wound up on the roller pipe 3 at a contact area 41.

[0076] In this state, the set bar 1 and the second tip 112 are in contact, and the screen 4 wrapped around the periphery of the weight bar 30 and the screen 4 wound around the roller pipe 3 are in contact at the contact area 41, so the roller pipe 3 cannot be rotated counterclockwise any further.

[0077] At this time, there is a certain gap between the screen 4 wound around the roller pipe 3 and the first tip portion 111. In other words, the screen 4 wound around the roller pipe 3 and the first tip portion 111 are in a non-contact state.

[0078] 2.2. Second embodiment of the present invention The second embodiment of the present invention will be specifically described below with reference to the drawings. In the following description, differences from the solar shading device 100 according to the above embodiment will be mainly described, and the same parts will be designated by the same names or reference numerals and will not be described again.

[0079] FIG. 11 is a front view (A) and a side view (B) showing the overall configuration of a solar shading device according to a second embodiment of the present invention. FIG. 12 is a side view showing the positional relationship when the operating tool support device according to the second embodiment of the present invention is raised to the uppermost position.

[0080] The solar shading device 100B according to this embodiment differs from the solar shading device 100 according to the first embodiment in that the set bar 1B is attached via brackets to a wall surface in the rear direction (arrow B) rather than to a ceiling in the upward direction (arrow U). Accordingly, side holders 2B are attached to both ends of the set bar 1B so as to extend in the short direction (arrow FB).

[0081] Other than the above, the configuration is the same as that of the solar shading device 100 according to the first embodiment.

[0082] 12 shows a state in which the screen 4 is wound up by the roller pipe 3 that holds the screen 4, and the second tip 112 of the storage section 11 comes into contact with the roller pipe holding section that rotatably holds the roller pipe 3. At this time, the weight bar 30 stored in the storage section 11 comes into contact with the screen 4 wound up on the roller pipe 3 at a contact area 41B.

[0083] In this state, the set bar 1B and the second tip 112 are in contact, and the screen 4 wrapped around the periphery of the weight bar 30 and the screen 4 wound around the roller pipe 3 are in contact at the contact area 41B, so the roller pipe 3 cannot be rotated counterclockwise any further.

[0084] At this time, similar to the solar shading device 100 according to the first embodiment, there is a certain gap between the screen 4 wound around the roller pipe 3 and the first tip portion 111. In other words, similar to the solar shading device 100 according to the first embodiment, the screen 4 wound around the roller pipe 3 and the first tip portion 111 are in a non-contact state.

[0085] 2.3. [Third embodiment of the present invention] The third embodiment of the present invention will be specifically described below with reference to the drawings. In the following description, differences from the operating tool support device 50 according to the above embodiment will be mainly described, and the same parts will be designated by the same names or reference numerals and will not be described again.

[0086] FIG. 13 is a perspective view showing the configuration of an operating tool support device according to the third embodiment of the present invention.

[0087] The operating tool support device 50C of this embodiment differs from the operating tool support device 50 of the first and second embodiments in that it has an operating tool 20C having an approximately C-shape instead of the operating tool 20 having an approximately conical shape and the string-like support 21 connected to the operating tool 20.

[0088] Other than the above, the configuration is the same as that of the operating tool support device 50 according to the first and second embodiments.

[0089] The operating tool 20C has a substantially C-shape, is held by a user, and is used to wind and unwind the screen 4 in response to the user's operation. The shape and size of the operating tool 20C can be determined as desired.

[0090] The groove-like second hole 15 provided in the accommodating section 11 has a shape that allows the substantially C-shaped operating tool 20C to engage with the operating tool support member 10. Specifically, the second hole 15 has a groove depth that matches the diameter of the support tool 21C of the operating tool 20C, and the support tool 21C can be placed on the upper side of the second hole 15.

[0091] As described above, the operating tool support member 10 according to the embodiment of the present invention is the operating tool support member 10 of the operating tool support device 50, 50C that is attached to the weight bar 30 arranged at the lower end of the screen 4 of the solar shading device 100 and is used for winding and unwinding the screen 4, and is provided with a storage section 11 for storing the weight bar 30 and a pressing tool 12 for fixing the weight bar 30 inside the storage section 11, and the storage section 11 has a shape of a side surface of the area that stores the weight bar 30. The weight bar 30 has a first tip portion 111 which is one of the circumferential ends, and a second tip portion 112 which is the other end of the first tip portion 111 among the circumferential ends in the area that accommodates the weight bar 30 and has an area for attaching the pressing device 12, and at least a part of the outer circumferential line of the weight bar 30 is positioned radially outward of the weight bar 30 than a straight line 115 connecting the first tip portion 111 and the second tip portion 112 when the weight bar 30 is accommodated in the accommodation section 11.

[0092] According to this, the screen 4 is wound up by the roller pipe 3 that holds the screen 4, the operating tool support member 10 rises, and the second tip 112 of the storage section 11 comes into contact with the roller pipe holding section that holds the roller pipe 3 rotatably, that is, when the roller pipe 3 cannot be rotated any further counterclockwise and the operating tool support member 10 has risen to the top, the weight bar 30 stored in the storage section 11 comes into contact with the screen 4 wound up on the roller pipe 3 at the contact area 41. Even when the operating tool support member 10 is raised to the top, the biasing force of the spring mechanism built into the winding device acts, and a force pressing the screen 4 acts on the weight bar 30. However, there is a certain gap between the screen 4 wound around the roller pipe 3 and the first tip portion 111, and the screen 4 wound around the roller pipe 3 and the first tip portion 111 are not in contact with each other. In other words, it is possible to prevent the screen 4 from being left with contact marks due to contact with the storage section 11. Therefore, according to the operation tool support member 10, it is possible to realize an operation tool support member 10 that does not leave a mark on the screen 4.

[0093] Furthermore, the first tip 111 and the second tip 112 are not provided with claws for engaging with the weight bar 30. This eliminates the need to visually check the engaging portions of the first tip 111 and the second tip 112 while aligning them with the opening 31 of the weight bar 30, thereby improving workability.

[0094] Furthermore, since the first tip 111 and the second tip 112 do not have claw portions for engaging with the weight bar 30, when the weight bar 30 with the screen 4 wrapped around it is stored in the storage section 11, it is possible to prevent the screen 4 from wrinkling due to contact with the claw portions. Furthermore, since the storage section 11 can be attached to the weight bar 30 even when the lower end of the screen 4 is wrapped around the periphery of the weight bar 30, the volume of the storage section 11 is sufficient even when taking into account the thickness of the screen 4, and it is possible to prevent wrinkles from occurring in the screen 4 when the storage section 11 is attached to the weight bar 30 around which the screen 4 is wrapped. That is, it is possible to provide the operating tool support devices 50, 50C with excellent design.

[0095] In addition, the operating tool support member 10 has a shape in which the storage section 11 comes into contact with the screen 4 wound up on the roller pipe 3 when the screen 4 is wound up by the roller pipe 3 that holds the screen 4 and the storage section 11 comes into contact with the roller pipe holding section that holds the roller pipe 3 rotatably.

[0096] According to this, when the screen 4 is wound up by the roller pipe 3 that holds it and the second tip 112 of the storage section 11 comes into contact with the roller pipe holding section that rotatably holds the roller pipe 3, the weight bar 30 stored in the storage section 11 comes into contact with the screen 4 wound around the roller pipe 3 at the contact area 41, so there is a certain gap between the screen 4 wound around the roller pipe 3 and the first tip 111, and the screen 4 wound around the roller pipe 3 and the first tip 111 are in a non-contact state. Therefore, it is possible to prevent contact marks from being left on the screen 4 due to contact with the storage section 11.

[0097] In addition, the operating tool support member 10 has the pressing tool 12 connected to the second tip portion 112 via a rotating shaft 121, and the weight bar 30 is clamped between the storage portion 11 and the pressing tool 12, thereby fixing the operating tool support member 10.

[0098] According to this, by rotating the pressing tool 12, the weight bar 30 can be sandwiched between the accommodation portion 11 and the pressing tool 12, and the operating tool support member 10 can be fixed. In addition, by rotating the pressing tool 12, the fixed position of the operating tool support member 10 can be released, and the operating tool support member 10 can be easily removed from the weight bar 30.

[0099] In addition, the operating tool support member 10 has an opening 31 for the weight bar 30, and the storage section 11 further has a protrusion 13, which is an area that protrudes toward the center of the storage section 11, in at least a portion of the area that stores the weight bar 30, and the protrusion 13 engages with the opening 31 of the weight bar 30.

[0100] This allows the user to easily secure the weight bar 30 in a fixed position by engaging the protrusion 13 provided on the storage section 11 with the opening 31 of the weight bar 30. Furthermore, the protrusion 13 can restrict the rotation of the weight bar 30, making it possible to further stabilize the position of the weight bar 30 in the storage section 11.

[0101] In addition, the operating tool support member 10 has the storage section 11 provided with holes 14, 15 for connecting operating tools 20, 20C used for winding and unwinding operations of the screen 4, and the operating tools 20, 20C have an approximately conical or C-shaped configuration, and the holes 14, 15 further include a first hole 14 for fitting a string-like support tool 21 connected to the approximately conical operating tool 20 into the operating tool support member 10, and a second hole 15 for engaging the approximately C-shaped operating tool 20C with the operating tool support member 10.

[0102] This allows the user to easily connect the operating tools 20, 20C used for winding and unwinding the screen 4 to the storage section 11. Furthermore, the user can connect operating tools 20, 20C having different shapes, such as an operating tool 20 having a generally conical shape and an operating tool 20C having a generally C-shape, to a single operating tool support member 10. In other words, the user can connect any of the operating tools 20, 20C having different shapes to the operating tool support member 10, and can easily use either of the operating tool support devices 50, 50C.

[0103] Furthermore, in the operating tool support member 10, the back region 122 of the pressing tool 12 is positioned more inward than the back portion 113 of the storage section 11 when the weight bar 30 is fixed to the storage section 11 by the pressing tool 12.

[0104] According to this, when the weight bar 30 is fixed to the housing portion 11 by the pressing tool 12, the back region 122 of the pressing tool 12 is located inside the back part 113 of the housing portion 11, so that even if a person or object passes near the operating tool support member 10 or the operating tool support member 10 comes into contact with a wall surface, it is possible to prevent the pressing tool 12 from rotating unintentionally. In other words, it is possible to reduce the risk of the weight bar 30 being unintentionally detached from the housing portion 11.

[0105] Moreover, the operating tool support devices 50, 50C according to the embodiments of the present invention include operating tools 20, 20C used for winding and unwinding the screen, and the operating tool support member 10 described above.

[0106] The above-mentioned operating tool support devices 50, 50C can prevent contact between the storage section 11 of the operating tool support member 10 and the screen 4, thereby realizing operating tool support devices 50, 50C that do not leave marks on the screen 4 from the operating tool support member 10.

[0107] 3. Extension of the embodiment of the present invention The invention made by the inventor has been specifically described above based on an embodiment, but it goes without saying that the invention is not limited thereto and can be modified in various ways without departing from the spirit of the invention.

[0108] The operating tool support member 10 in the above-described embodiment is provided with the first hole 14 and the second hole 15 for connecting the operating tools 20, 20C used for winding and unwinding the screen 4. However, the present invention is not limited to this, and in order to simplify the manufacturing process, only one of the first hole 14 and the second hole 15 may be provided so that only one of the operating tool 20 and the operating tool 20C can be connected.
