The winding pipes 5a and 5b are displaced in the front-rear direction and are supported by the side bracket 40 and the side plate 4a. The screens 6a and 6b may have different patterns, different materials, and different shielding levels, but may have the same pattern, the same material, and the same shielding degree.

(Configuration of side bracket 40)
Next, the detailed structure of the side bracket 40 is demonstrated using FIG.2 and FIG.3. FIG. 2 is a perspective view of the side bracket according to the present embodiment, and FIG. 3 is a perspective view of the side bracket with the closing cover removed. The side bracket 40 includes a side plate 4b (see FIG. 6A) provided at one end of the set frame 3, a base 41 that accommodates an operation unit 411 that is an adjusting device, and a base cover that covers the base 41. 42, a closing cover 43 as a detachable lid member that closes the elliptical opening 421 formed in the base cover 42, and a base support portion 44 for supporting the base cover 42 on the end of the set frame 3 And an operation chain 45 for rotating the winding pipes 5a and 5b to move the screens 6a and 6b up and down. The base 41 is connected to the side plate 4b, and the base 41 and the base cover 42 are connected via screws 46, and the base 41 and the base cover 42 form a storage device main body. In the present embodiment, the side plate 4b, the base 41, and the base cover 42 are described as separate members. However, they may be formed integrally with the same member.

(Configuration of base 41)
As shown in FIG. 3, the base 41 includes a plane part 41a, an inclined part 41b adjacent to the plane part 41a, an operation part 411 as a mechanism part for adjusting the opening / closing degree of the screen 6a, and an operation part. A stopper mechanism 412 for suppressing the operation of 411 and a pair of hole portions 413 as locking holes are provided. Further, the flat portion 41 a, the inclined portion 41 b, the operation portion 411, the stopper mechanism 412, and the hole portion 413 are exposed from the opening 421 of the base cover 42.

  The flat surface portion 41 a forms the bottom surface of the opening 421, and supports the closing cover 43 so as to be swingable in a direction perpendicular to the opening surface of the opening 421 using a predetermined portion of the closing cover 43 as a fulcrum. Specifically, when the closing cover 43 is fitted in the opening 421, the flat surface portion 41 a abuts a part of the back surface of the closing cover 43 and supports the closing cover 43.

  On the other hand, the inclined portion 41b forms the upper end portion of the periphery in FIG. 3 in the opening 421, and the depth direction (base) of the opening 421 from the boundary 41c with the adjacent flat portion 41a toward the upper end of the periphery of the opening 421. 41 is a so-called tapered surface inclined so as to continuously increase in depth. When the closing cover 43 is supported by the flat surface portion 41a, the inclined portion 41b presses the upper end portion 43a of the closing cover 43, that is, the portion where the closing cover 43 covers the inclined portion 41b, and the upper end portion 43a is deep. It is possible to insert in the direction. Thus, by fitting the upper end portion 43a in the depth direction, the other end can protrude from the surface of the opening 421 in the direction opposite to the depth direction, and the closing cover 43 can be easily removed. . Here, the depth direction is referred to as a pressing direction, and the reverse direction of the depth direction is referred to as a pulling direction.

  The operation unit 411 is an adjusting device such as a screw connected to the winding pipe 5a to adjust the opening / closing degree of the screen 6a and adjust the vertical position (winding upper limit position) of the screen 6a in the winding state. . Specifically, the operation unit 411 is connected to an adjustment mechanism (not shown) that adjusts the vertical position of the screen 6a provided in the winding pipe 5a by rotating the axis of the winding pipe 5a. By this, it is connected to the winding pipe 5a. For example, by performing an operation of rotating the operation unit 411 in the circumferential direction, the adjustment mechanism can be driven and the vertical position of the screen 6a can be adjusted. As the adjusting mechanism, any known mechanism can be used.

  The stopper mechanism 412 is a switching lever, for example, and suppresses the rotation of the operation unit 411 by switching the lever. It is preferable that the operation unit 411 and the stopper mechanism 412 are provided flat with the flat portion 41a or pushed into the flat portion 41a so as not to protrude from the flat portion 41a. In the present embodiment, the stopper mechanism 412 is provided so as to cover the range of the inclined portion 41b. However, the present invention is not limited to this, and the stopper mechanism 412 may be provided only on the flat portion 41a.

  The hole portion 413 includes a groove portion 41a-1 provided on a side surface of the flat surface portion 41a parallel to the vertical direction, an inner wall surface 421a of the opening 421 of the base cover 42, and a concave portion 421b formed on the inner wall surface 421a side (see FIG. 6 (c)) and a rectangular hole parallel to the vertical direction. The hole portion 413 is formed as an engaging portion into which a leg portion 431 of the closing cover 43 described later is fitted, and the closing portion 43 is locked by engaging the leg portion 431 with the hole portion 413. Is possible. The concave portion 421 b is engaged with the convex portion (projection) 432 of the leg portion 431. Note that the concave portion 421b may be provided not on the inner wall surface 421a side of the opening 421 but on the groove portion 41a-1 side according to the position of the convex portion 432. From the viewpoint of enabling the end of the closing cover 43 to be pressed, the hole 413 is provided at a location other than the inclined portion 41b, in other words, at a location other than the location where the closing cover 43 is pressed. preferable.

  From the viewpoint of enabling easy removal of the closing cover 43, the shape of the hole 413 is such that when the closing cover 43 is pressed, one end 43a of the closing cover 43 that is pushed in and the opposite side of the one end 43a. It is preferable to make it the rectangular shape extended in parallel with the straight line which the other end part located in a. Thus, if it is a rectangular shape parallel to the straight line, when the closing cover 43 is pressed, the leg portion 431 of the closing cover 43 can easily slide in the hole 413. Furthermore, in order to enable this sliding, the length of the hole portion 413 in the linear direction is preferably longer than the length of the leg portion 431 in the linear direction. More preferably, each length from the center in the straight line direction to the surface perpendicular to the straight line direction in the hole 413 is set to a length from the center in the straight line direction length in the leg portion 431 to the surface perpendicular to the straight line direction. Make it longer than the length.

(Configuration of closing cover 43)
As shown in FIG. 3, the closing cover 43 is a plate-like member having the same shape as the opening 421 so that the opening 421 can be closed when fitted into the opening 421. The thickness of the closing cover 43 is the length from the surface of the opening 421 to the flat portion 41a so that the surface of the base cover 42 and the surface of the closing cover 43 are flush with each other when the closing cover 43 is fitted in the opening 421. Preferably they are the same.

  The closing cover 43 has a pair of leg portions 431 at one end of the peripheral edge of the back surface facing the opening 421. Here, the following description will be made with the direction in which the leg portions 431 face each other as an inward direction and the opposite direction as an outward direction. The leg portion 431 has a flat plate shape parallel to each other, and a convex portion 432, which is a columnar projection for engaging with the concave portion 421b of the hole portion 413, is provided outwardly at the tip. Note that the convex portion 432 may be provided inward depending on the position of the concave portion 421b. By inserting the leg portion 431 into the hole portion 413, the leg portion 431 and the hole portion 413 are fitted, the convex portion 432 and the concave portion 421b of the hole portion 413 are engaged, and the closing cover 43 is engaged. It is stopped and its fall is prevented.

  When the leg portion 431 is inserted into or removed from the hole portion 413, the convex portion 432 and the inner wall surface of the hole portion 413, that is, the inner wall surface 421a of the opening 421 come into contact with each other, so that the leg portion 431 bends inward. Become. Therefore, the leg portion 431 is preferably formed of a material having a certain degree of hardness and elastic force, and examples of such a material include a hard resin material such as polycarbonate.

  In addition, in order to implement | achieve the bending of the leg part 431 mentioned above, the length (width) of the hole part 413 in the direction where the two hole parts 413 oppose is larger than the length (thickness) of the leg part 431 in the said opposing direction. Longer is preferred. More specifically, in a state where the closing cover 43 is fitted in the opening 421, the outer surface of the leg 431 contacts the inner wall surface of the hole 413, that is, the inner wall surface 421a of the opening 421, and the inner wall surface 421a The length of the facing direction of the hole portion 413, that is, the length of the groove portion 41a-1, is increased so that the inner wall surface of the facing hole portion 413, that is, the groove portion 41a-1 and the inner surface of the leg portion 431 are separated from each other. It is preferable. As a result, when the closing cover 43 is removed, the leg portion 431 bends inward and elastically presses outward, and the leg portion 431 slides while urging the inner wall surface 421a. Move. Therefore, even when the closing cover 43 is removed, the closing cover 43 does not fall due to the urging force of the leg portion 431.

  The operation chain 45 shown in FIG. 3 is a chain member for rotating the winding pipes 5a and 5b to move the screens 6a and 6b up and down. The operation chain 45 is supported by the base 41 so as to be rotatable, and a part of the operation chain 45 is wound around a pulley (not shown) that transmits the rotation to the take-up pipes 5a and 5b. The operation chain 45 can rotate the pulley by being pulled vertically downward by the user. Specifically, when the chain 45a on the front side (screen 6a side) of the operation chain 45 is pulled, the take-up pipe 5a is rotationally driven, and the screen 6a can be moved up and down. On the other hand, when the chain 45b on the rear side (screen 6b side) of the operation chain 45 is pulled, the winding pipe 5b is driven to rotate, and the screen 6b can be moved up and down.

(Function)
Hereinafter, a method of removing the closing cover 43 will be briefly described with reference to FIG. FIG. 4 is a partially enlarged view of the side bracket showing a process of removing the closing cover. FIG. 4A shows a state where the closing cover 43 closes the opening 421, and FIG. 4B shows a closing cover 43. The upper end part is shown pressed in the pressing direction, and (c) shows the state where the closing cover 43 is removed.

  First, in a state where the closing cover 43 as shown in FIG. 4A closes the opening 421, as shown in FIG. 4B, when the upper end portion 43a is pressed, the flat portion 41a and the inclined portion are inclined. The boundary 41c with the portion 41b serves as a fulcrum (similarly, the location on the back surface of the closing cover 43 that contacts the boundary 41c also serves as a fulcrum), and only the upper end 43a of the closing cover 43 is pushed. Thereafter, the back surface of the closing cover 43 and the inclined portion 41b of the opening 421 come into contact with each other, and the pushing of the closing cover 43 is suppressed by the tapered surface of the inclined portion 41b. When the back surface of the closing cover 43 and the inclined portion 41 b come into contact with each other, the lower end portion of the closing cover 43 protrudes from the surface of the base cover 42. Therefore, as shown in FIG. 4C, the closing cover 43 can be easily removed from the opening 421 by grasping the protruding lower end and pulling it up from the surface of the base cover 42.

  Next, a method for removing the closing cover 43 will be described in more detail with reference to FIGS. 5 is a front view of the side bracket according to the present embodiment, FIG. 6 is a cross-sectional view taken along the line AA of FIG. 5, and FIG. -B line sectional drawing, (c) is also a CC line sectional view. 7A is a cross-sectional view taken along the line AA of FIG. 5, FIG. 7B is a cross-sectional view taken along the line BB, and FIG. 7C is a cross-sectional view taken along the line CC. FIG. 8 is a cross-sectional view taken along line AA of FIG. 5, FIG. 8B is a cross-sectional view taken along line BB, and FIG. FIG. 9A is a cross-sectional view taken along the line AA in FIG. 5, FIG. 9B is a cross-sectional view taken along the line BB, and FIG. 9C is a cross-sectional view taken along the line CC. FIG. 10 is a cross-sectional view taken along the line A-A in FIG. 5, (b) is a cross-sectional view taken along the line BB, and (c) is a cross-sectional view taken along the line CC in the state where the closing cover is completely removed. It is line sectional drawing.

  First, as shown in FIGS. 5 and 6A and 6B, when the closing cover 43 is fitted in the opening 421, the back surface of the closing cover 43 and the flat portion 41a of the opening 421 come into contact with each other. A space is formed between the back surface and the inclined portion 41b. Further, as described above, since the thickness of the closing cover 43 and the depth of the opening 421 are the same, the surface of the base cover 42 and the surface of the closing cover 43 are in the same plane. Further, the vertical length of the hole portion 413 is longer than the vertical length of the leg portion 431. In this state, the convex part 432 of the leg part 431 is engaged with the concave part 421b. Further, as shown in FIG. 6C, the outer surface of the leg portion 431 contacts the inner wall surface of the hole portion 413, that is, the inner wall surface 421a of the opening 421, and the inner surface of the hole portion 413 facing the inner wall surface 421a. The wall surface, that is, the groove 41a-1 and the inner surface of the leg 431 are separated from each other to form a space.

  7A, when the upper end portion 43a of the closing cover 43 is pressed, the boundary 41c between the flat portion 41a and the inclined portion 41b of the opening 421 is used as a fulcrum, and only the upper end portion 43a is present. It is pushed into the inclined part 41b. When the upper end portion 43a is pressed, the lower end portion of the closing cover 43 is pulled up by the principle of scissors using the boundary 41c, and the back surface of the lower end portion of the closing cover 43 and the flat portion 41a start to be separated. At this time, as shown in FIGS. 7B and 7C, the leg portion 431 slides in the vertical direction and the pulling direction in the hole portion 413, and the engagement between the convex portion 432 and the concave portion 421b is released. In addition, the leg portion 431 is bent inward.

  From this state, as shown in FIG. 8, when the upper end portion 43a of the closing cover 43 is further pressed, the back surface of the upper end portion 43a of the closing cover 43 and the inclined portion 41b come into contact, and the upper end portion 43a is pushed in. It is suppressed. In this state, the leg portion 431 slides in the vertical direction and the pulling direction in the hole portion 413 from the state shown in FIG. 7, and the engagement between the convex portion 432 and the concave portion 421b is released. In this state, the lower end portion of the closing cover 43 protrudes from the surface of the base cover 42, and a space is formed between the back surface of the lower end portion and the surface of the base cover 42. For example, by inserting a nail or the like into this space and pulling up the closing cover 43, or by gripping and pulling up the protruding lower end portion, the engagement between the convex portion 432 and the concave portion 421b as shown in FIG. Can be released easily. Furthermore, if it continues to pull up as it is, as shown in FIG. 10, the closing cover 43 can be completely removed.

  As described above, according to the present embodiment, the operation unit 411 can be selectively covered by the closing cover 43. Therefore, even when the size of the side bracket is enlarged, the operation portion 411 can be covered regardless of the shape of the side bracket, and it is not necessary to make a change according to the shape of the side bracket. I can plan.

  Further, when the upper end portion 43a of the closing cover 43 is pressed, the engagement between the convex portion 432 and the concave portion 421b can be released with a light pressing force using the principle of scissors by the flat portion 41a, the inclined portion 41b, and the boundary 41c. it can. Further, the closing cover 43 can be easily removed simply by pressing the upper end portion 43 a of the closing cover 43 and pulling up the other part, and can be easily attached only by fitting the closing cover 43 into the opening 421. . Furthermore, since the surface of the base cover 42 and the surface of the closing cover 43 are located on the same plane, a continuous plane can be formed, there is no sense of design discomfort, and the aesthetic appearance of the side bracket 40 is not impaired. . In addition, since the inclined portion 41b has a tapered surface, even if the closing cover 43 is pressed with an excessively high pressing force, the taper surface suppresses the pushing, so that the base cover 42 is damaged or the closing cover 43 is It is possible to prevent accidental disconnection.

  Further, as in Patent Document 1 described above, when the engagement state of the cover is maintained using the elasticity of the resin, it is difficult to release the engagement unless a soft resin is used to some extent. However, according to the present embodiment, even if a hard resin is adopted for each element constituting the side bracket 40, the closing cover 43 can be easily attached and detached.
