Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the conventional shutter device as described above, a direct dustproof and rainproof function can be exerted on the shutter curtain wound around the winding body covered by providing the shutter case and a drive control unit configured to include electric and electronic devices such as an opening / closing machine and a control unit, and it is adopted as a suitable one. While providing a shutter case in this manner helps prevent direct exposure of the drive control unit to rainwater, the recent trend of worsening weather due to global warming, and the arrival of large typhoons and other severe weather conditions, it is anticipated that rainwater, carried by strong winds through the lintel at the rear of the lower end of the shutter case, may penetrate (be blown into) the shutter case, pass through the winding mechanism, and reach the drive control unit located at the front. Furthermore, it is conceivable that when the shutter curtain is wound in a spiral shape onto the winding mechanism, rainwater adhering to the shutter curtain may be scattered and land on the drive control unit located in front of it. However, since the drive control unit is composed of components equipped with electrical and electronic parts, it is undesirable for water to come into contact with it, even if waterproofing treatment has been applied. Therefore, the problem to be solved by the present invention is to prevent (avoid) rainwater from coming into contact with the drive control unit, which is located at the front of the shutter case, in the event of such an abnormal situation. [Means for solving the problem]

[0005] The present invention was created in view of the above circumstances and with the aim of solving these problems, and the invention of claim 1 is a building shutter device comprising: guide rails provided on the left and right sides of a building opening; a shutter curtain that is guided up and down by the guide rails to open and close the opening; a winding body disposed above the opening and on which the shutter curtain is wound; a drive control unit disposed in front of the winding body and controlling the rotational drive of the winding body; and a shutter case that covers the winding body and the drive control unit, wherein a partition body is provided inside the shutter case to separate the winding body and the drive control unit. In this regard, the shutter case comprises a drive-side case portion that covers one end portion in the left-right direction where the drive control unit is located, and a main body-side case portion that covers the portion excluding the portion covered by the drive-side case portion. The drive-side case portion is provided so as to protrude forward from the main body-side case portion, and the partition is arranged inside the drive-side case portion. This is a shutter device for buildings characterized by the following features.

The invention of claim 5 is characterized in that the partition is provided to be movable in the left-right direction so as to be able to open part or all of the portion covered by the partition. 1 This is a shutter device for the building described. The invention of claim 6 is characterized in that the partition is positioned behind the front case plate of the main body side case portion, and the opened partition moves so as to overlap with the front case plate of the main body side case portion on the inside of the case. 5 This is a shutter device for the building described. The invention of claim 7 is characterized in that the partition is provided to be movable in the vertical direction so as to be able to open part or all of the portion covered by the partition. 1 This is a shutter device for the building described. The invention of claim 8 is, In a building shutter device comprising guide rails provided on the left and right sides of a building opening, a shutter curtain that is guided up and down by the guide rails to open and close the opening, a winding body positioned above the opening on which the shutter curtain is wound, a drive control unit positioned in front of the winding body to control the rotational drive of the winding body, and a shutter case covering the winding body and the drive control unit, when providing a partition body within the shutter case to separate the winding body and the drive control unit, The partition is characterized by being divided into left and right sections and consisting of multiple removable partition plates. do This is a shutter device for buildings. [Effects of the Invention]

[0006] By adopting the invention of claim 1, a winding body on which the shutter curtain is wound and a drive control unit located in front of the winding body are arranged inside the shutter case, and the winding body and the drive control unit are separated by a partition body. As a result, rainwater that enters the shutter case due to strong winds, or rainwater scattered during the winding process of the shutter curtain, is prevented from falling on the drive control unit in front by the partition body, thereby effectively protecting the drive control unit from rainwater. Moreover In a shutter case structure where the drive-side case portion covering the drive control unit protrudes forward more than the main body-side case portion, the partition is positioned in the drive-side case portion, thereby simplifying the shutter case structure. Claim 2 By making this invention, the partition body becomes removable, which in turn makes it easier to maintain components such as the winding body located behind the partition body. Claim 3 This invention allows the partition body to be removed from both the upper and lower edges at a point forward of the winding body's axis, making it easier to remove the partition body for maintenance work. Claim 4 By adopting this invention, the partition body's upper edge can be removed from the rear side, and its lower edge can be removed in front of the winding body's axis, making it easy to remove the partition body for maintenance work. Claim 5 This invention allows for easy maintenance of the inner area by moving the partition body from side to side, thereby opening up the area previously partitioned by the partition body and improving work efficiency. Claim 6 As a result of this invention, the partition body in the open position, which has moved in the left-right direction, overlaps with the front panel of the case on the main body side, and the partition body in the open position is stored in the case on the main body side, eliminating the need to secure a separate storage compartment. Claim 7By making the invention as described above, the partition body can move vertically and be opened, and as a result, it can perform opening and closing movement by effectively utilizing the outer peripheral space of the shutter curtain wound around the winding body. Claim 8 By making the invention as described above, In a system where a winding body on which the shutter curtain is wound and a drive control unit located in front of the winding body are arranged inside a shutter case, the winding body and the drive control unit are separated by a partition. As a result, rainwater that enters the shutter case due to strong winds, or rainwater scattered during the winding process of the shutter curtain, is prevented from hitting the drive control unit in front by the partition, thus providing effective protection for the drive control unit from rainwater. Moreover As a result of the partition body being divided into left and right parts, when performing maintenance on the winding body or the like, it is sufficient to remove the partition body of the part to be maintained, and the workability is improved.

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawing, 1 is a shutter device installed in an opening E such as an entrance to a building, and the shutter device 1 is configured as conventional, with various components and devices such as: guide rails 2 provided on the left and right sides of the opening E; a shutter curtain 3 that is guided up and down by the guide rails 2 to open and close the opening E; a winding body (winding drum, winding wheel) 4 positioned above the opening E to wind up the shutter curtain; an electric opening and closing mechanism 5a positioned at the front part of one end of the winding body 4 in the left and right directions and linked to the winding body 4 via a power transmission part 5c such as a chain transmission mechanism to rotate the winding body 4; and a control unit 5b positioned above (near) the opening and closing mechanism 5a to control the drive of the opening and closing mechanism 5a; and a shutter case 6 positioned so as to protrude (extend) forward from the wall (structure side member) W above the opening E and covering the winding body 4 and the drive control unit 5.

[0009] The shutter case 6 comprises a main body side case portion 7 that covers a wide area on both sides except for the left-right end portion where the drive control unit 5 is located, and a drive side case portion 8 that covers the left-right end portion where the drive control unit 5 is located. Brackets 9 and 10 are provided on both the left and right edges of the shutter case 6, supporting the left and right ends of the winding body 4. A lintel portion 6a is formed on the lower edge of the wall portion W of the shutter case 6, with an opening corresponding to the area between the upper edges of the left and right guide rails 2 to allow the shutter curtain 3 to move in and out of the shutter case 6. Incidentally, the shutter case 6 may also have a case rear plate (case back plate) on the wall portion W side.

[0010] The main body case section 7 is equipped with a case top plate (case top plate) 7a, a case front plate (case front plate) 7b, and a case bottom plate (case bottom plate) 7c that cover the top, front, and bottom of the winding body 4, and has a general-purpose U-shaped structure in side view with an opening on the wall section W on the rear frame side. The drive-side case section 8, like the main body-side case section 7, is U-shaped in side view with an open wall W side, and is equipped with a case top plate 8a, a case front plate 8b, and a case bottom plate 8c. However, the case front plate 8b is positioned to protrude forward in a stepped manner relative to the case front plate 7b of the main body-side case section 7, as it is also necessary to cover the drive control unit 5 located in front of the winding body 4. In contrast, the upper case plate 8a and lower case plate 8c of the drive-side case section 8 are provided flush with the left-right surface relative to the upper case plate 7a and lower case plate 7c of the main body-side case section 7. However, since the front drive control unit 5 also needs to be covered, the upper case plate 7a and lower case plate 7c of the main body-side case section 7 extend further forward than the upper case plate 7a and lower case plate 7c of the main body-side case section 7.

[0011] As mentioned above, in the drive-side case section 8, the case upper plate 8a and case lower plate 8c extend forward relative to the case upper plate 7a and case lower plate 7c of the main body-side case section 7. Therefore, if left as is, the inner edges of the drive-side case section 8 adjacent to the main body-side case section 7 would be open. To cover this open inner portion, an inner case plate 8e is provided. Incidentally, the front case plates 7b and 8b of both case sections 7 and 8 are removable inspection plates, allowing for maintenance of various parts inside the shutter case 6 when necessary. Furthermore, the lower case plates 7c and 8c of both case sections 7 and 8 are provided with removable inspection plates 7d and 8d, allowing for maintenance of various parts inside the shutter case 6 when necessary. Furthermore, the shutter case 6 can also be made by extending the front plate 7b of the main body case section 7 to the same front position as the front plate 8b of the drive side case section 8. In this case, the shutter case 6 does not have an extension (protrusion) in the drive side case section 8, and the width in the front-to-back direction is the same, making the aforementioned inner case plate 8e unnecessary and thus simplifying the case structure. However, the main body case section 7 becomes larger due to the forward extension.

[0012] On the other hand, of the brackets 9 and 10, the driven bracket 9 is positioned at the left and right outer end portion of the main body case portion 7, and is provided such that its rear end edge is fixed to the wall portion W, and as described above, it supports the driven end of the winding body 4. The drive-side bracket 10 is also positioned at the left and right outer ends of the drive-side case portion 8, and is provided such that its rear edge is fixed to the wall portion W, thereby supporting the drive-side end of the winding body 4. The drive-side bracket 10 is provided with an extension portion 10a that extends forward, and the drive control unit 5 is attached to this extension portion 10a. Incidentally, the extension portion 10a can be either an integral part of the drive-side bracket 10, made longer in the front-rear direction, or a separate component connected to it.

[0013] Within the drive-side case section 8, a partition body 11 is provided that separates the space between the winding body 4 and the drive control unit 5, specifically between the outermost trajectory of the shutter curtain 3 wound around the winding body 4 and the drive control unit 5. This partition body 11 is configured to capture rainwater that enters the shutter case from the lintel section 6a due to strong winds, and rainwater that is scattered forward from the shutter curtain 3 when it is wound around the winding body 4, thereby efficiently preventing the rainwater from getting on (adhering to) the drive control unit 5 in front. While various embodiments of the partition body 11, as described later, can be proposed, the present invention is of course not limited to these embodiments.

[0014] To explain in more detail, the partition body 11 of the first embodiment is composed of partition plates 11x, 11y, and 11z that are divided into multiple (three in this embodiment) partition plates in the left-right direction, as shown in Figures 4 to 6. These partition plates 11x, 11y, and 11z are arranged so that adjacent left and right edges are stacked (overlapping) with each other. The stacking structure in this case will be described later. These partition plates 11x, 11y, and 11z can also be arranged so that adjacent edges do not stack with each other and are butting against each other. Of course, the partition body 11 does not have to be of the divided type as in this embodiment, and may be a single plate.

[0015] In the following explanation, the partition plate 11 will be described as a single, integrated partition body 11, unless it is necessary to specifically describe it as divided partition plates 11x, 11y, and 11z. The partition body 11 has upper and lower edge portions 11a and 11b that are detachably attached to mounting brackets 8f and 8g on both the upper and lower sides of the case upper plate 8a and case lower plate 8c of the drive side case portion 8. This detachable structure may be one using screws (fasteners) 11c as described later, or a configuration in which the leading edge of the partition body 11 is detachably locked to a locking receiver provided on the shutter case 6 side, and these can be appropriately selected as needed.

[0016] In contrast, the left and right outer edges 11d of the partition body 11 do not extend to the power transmission section 5c that interlocks the front opening / closing mechanism 5a and the winding body 4, and are configured to avoid interference with the power transmission section 5c. Furthermore, the partition body 11 only needs to be large enough to cover the drive control unit 5 and prevent rainwater splashed from the shutter curtain 3 wound around the winding body 4 from hitting the drive control unit 5. Therefore, it is not necessary to provide it across the entire width of the shutter case 6. In this embodiment, where a drive-side case section 8 is provided, it is sufficient to make it small enough to fit within the drive-side case section 8. Of course, if the drive control unit 5 is close to the main body case 7 and exposure to rainwater is expected, the partition 11 can be made to extend into the main body case 7.

[0017] Next, the mounting structure of the partition body 11 in this embodiment will be described in detail. In this design, the partition body 11 has upper and lower edge portions 11a and 11b that can be detachably attached to upper and lower mounting brackets 8f and 8g provided on the drive-side case portion 8. In this case, the upper mounting bracket 8f is attached to the case top plate 8a above the space Sb between the winding body 4 and the drive control unit 5, and the leading edge (lower edge) of the upper mounting bracket 8f is bent into an L shape to form a locking receiving portion 8fa, and the upper edge 11a of the partition body 11 is configured to be detachably locked to the locking receiving portion 8fa.

[0018] On the other hand, the lower mounting bracket 8g is in the shape of an inverted L, and the upper piece 8ga of the lower mounting bracket 8g has an upright piece 8gb that protrudes upward from its front edge, and the lower edge 11b of the partition plate 11 is detachably attached to the upright piece 8gb via screws 11c. The attachment and detachment points of the upper and lower edges 11a and 11b of the partition plate 11, which are attached using the upper and lower mounting brackets 8f and 8g in this configuration, are located in front of the axis position 4a of the winding body 4. This configuration allows the attachment and detachment of the partition body 11 to be performed in front of the winding body 4.

[0019] In this embodiment, a receiver 15 for obstacle detection is provided on the front of the main body 8gc of the lower mounting bracket 8g. With the receiver 15 positioned in this way, the receiver 15 is configured such that the lower mounting bracket 8g acts as an extension member of the partition plate 11, preventing rainwater from splashing from the back of the partition plate 11. Incidentally, the receiver 15 is an electrical / electronic device and plays a role in the drive control of the drive control unit 5. Furthermore, the obstacle detection transmitter 15a is installed on the base plate 3a of the shutter curtain 3. When the shutter curtain 3 is closing, the transmitter 15a receives an obstacle detection signal from an obstacle detection means (not shown) installed on the base plate 3a and transmits a detection signal to the receiver 15. Upon receiving this detection signal, the receiver 15 is configured to perform a pre-set obstacle avoidance operation, such as emergency stopping the closing drive of the opener 5a, opening the curtain, or issuing an alarm.

[0020] Furthermore, in this design, the partition body 11 can be attached and detached via screws 11c. As a result, when performing maintenance on the winding body 4 side (rear side) of the power transmission unit 5c, or on the shutter curtain 3 and winding body 4 in the area covered by the partition body 11, the partition body 11 can be removed, allowing maintenance work to be performed without the partition body 11 getting in the way. This avoids the inconvenience of maintenance work being compromised by the partition body 11 being provided to prevent rainwater splashing inside the shutter case 6 from getting on the work.

[0021] Incidentally, as mentioned above, the partition body 11 in this embodiment is divided into partition plates 11x, 11y, and 11z. In this case, the part that requires frequent maintenance is the drive-side bracket 10 of the winding body 4 to which the power transmission unit 5c is connected. It is preferable to stack the partition plates 11x, 11y, and 11z such that the partition plate 11z closest to the power transmission unit 5c is placed at the front, and the partition plate 11x furthest from the power transmission unit 5c is placed at the rear. With this configuration, only the partition plate 11x closest to the power transmission unit 5c can be removed. As a result, inspection and maintenance work such as maintenance of the power transmission unit 5c and maintenance of the winding state of the shutter curtain 3 can be performed by removing only the partition plate 11x without removing the other partition plates 11y and 11z, thus improving work efficiency. Of course, maintenance work may be performed by removing either the partition plate 11y or 11z if necessary.

[0022] Thus, the partition body 11, which is provided to prevent rainwater that enters the shutter case 6 due to strong winds or rainwater scattered from the rolled-up shutter curtain 3 from falling onto the drive control unit 5 at the front, is not limited to a flat plate shape as in the first embodiment, but can be curved (arc-shaped) as in the second embodiment shown in Figure 7. When the partition body 11 is curved in this way, the area for capturing rainwater scattered inside the shutter case 6 can be made larger than that of the flat plate shape, which has the advantage of enabling more efficient capture of rainwater. Incidentally, even in this case, the partition body 11 can be of the segmented type as in the first embodiment.

[0023] In the second embodiment described above, a locking portion 11aa is formed at the tip of the upper edge portion 11a of the partition body 11, while an upper locking receiving portion 8h is provided on the wall portion W side of the case upper plate 8a, to which the locking portion 11aa is detachably locked and attached. Incidentally, the lower edge portion 11b of the partition body 11 may be attached and detached with screws 11c as in the first embodiment, but if the partition body 11 is curved, the partition body 11 should be curved or flat, which is larger (larger diameter) than the curved mounting shape in its natural state. Furthermore, with the locking portion 11aa, which is the upper edge, locked to the locking receiving portion 8h, the lower edge portion 11b of the partition body 11 is curved and forcibly deformed into the mounting shape (fitting shape), and the lower edge portion 11b is locked to the lower locking receiving portion 8gd provided on the upper surface of the upper piece portion 8ga of the lower mounting bracket. In this configuration, the springback (elastic restoration) function of the partition body 11 allows for attachment and detachment without the need for screws 11c, while the springback function helps maintain the mounting state (locked state, fitted state) of the partition body 11.

[0024] In each of the above embodiments, the partition body 11 is configured to be installed between the winding body 4 and the drive control unit 5 within the drive-side case section 8 (shutter case 6). In this case, the partition body 11 is configured to be detachable in order to perform maintenance on the part covered by the partition body 11. However, the partition body 11 may also be configured to be movable, as in the third and fourth embodiments described later, in order to enable the aforementioned maintenance. These embodiments will now be described in detail.

[0025] Furthermore, in the third embodiment shown in Figures 8 and 9, the partition body 11 is configured to be movable in the left-right direction so that it can move toward the main body side case portion 7. In this configuration, upper guide rails 12 are provided on the upper case plates 7a and 8a, extending from the drive side case portion 8 to the driven side case portion 7, while lower guide rails 13 are provided on the lower mounting brackets 7g and 8g provided on the lower case plates 7b and 8b. The upper and lower edges 11a and 11b of the partition body 11 can slide freely in the left-right direction on these upper and lower guide rails 12 and 13. Incidentally, the mounting brackets 7g and 8g can be configured as a single continuous unit. In other words, in this design, in order to allow the partition body 11 located in the drive-side case section 8 to move to the main body-side case section 7, the partition body 11 is positioned behind the case front plate 7b of the main body-side case section 7, that is, between the case front plate 7b and the winding body 4 in the front-to-back direction. Similarly, the upper and lower guide rails 12 and 13 are also configured to be positioned behind the case front plate 7b of the main body-side case section 7, that is, between the case front plate 7b and the winding body 4. The upper and lower edges 11a and 11b of the partition body 11 are assembled to the upper and lower rails 12 and 13 so as to be slidable in the left and right directions. With this configuration, the partition body 11 is positioned on the drive-side case 8 side and is configured to move from a closed position (partition position) that separates the winding body 4 and the drive control unit 5 to an open position that moves towards the main body-side case 8 side, either opening the entire section partitioned by the partition body 11 or opening it while leaving a portion open.

[0026] With this configuration, the partition body 11, positioned in a closed position, prevents rainwater that enters the shutter case 6 due to strong winds, or rainwater scattered from the shutter curtain 3 wound around the winding body 4, from hitting the drive control unit 5 at the front. However, during maintenance, the partition body 11 can be moved to the main body case 7 side to open it, allowing the area covered by the partition body 11 to be visible from the front with the case front plate 8b removed. This enables maintenance of components such as the drive control unit 5 located in the affected area without being obstructed by the partition body 11, thus ensuring that work efficiency is not compromised. In this case, the portion of the partition 11 that has moved to the main body side case portion 7 will be positioned to overlap (overlap, stack) with the front plate 7b of the main body side case portion 7 on the rear side (back of the case), and will not hinder the movement of the partition 11. Incidentally, in this design, the lower edge portion 11b is pressed against the lower guide rail 13 by a screw 13a screwed into the lower guide rail 13 to prevent the partition body 11 in the closed position from moving unintentionally.

[0027] On the other hand, as shown in the fourth embodiment in Figures 10-12, the partition body 11 may be configured to move up and down. In this configuration, arc-shaped left and right guide rails 14 are provided on the drive-side bracket 10 and the inner case plate 8e, and the left and right end edges 11e of the partition body 11 are guided to move up and down on these left and right guide rails 14. When providing the left and right guide rails 14, in this embodiment the guide rails 14 are directly attached to the drive-side bracket 10 and the inner case plate 8e, but they may also be attached to the drive-side bracket 10 via mounting brackets, or they may be attached to the drive-side case portion 8 via mounting brackets instead of the drive-side bracket 10.

[0028] In this embodiment, configured as described above, the shutter device 1 has a winding body 4 on which the shutter curtain 3 is wound, and a drive control unit 5 located in front of the winding body 4, with the winding body 4 and the drive control unit 5 separated by a partition 11. As a result, rainwater that enters the shutter case 6 due to strong winds, or rainwater scattered during the winding process of the shutter curtain 3, is prevented from falling onto the drive control unit 5 in front by the partition 11, thus providing effective protection for the drive control unit 5 from rainwater.

[0029] In this case, the shutter case 6 comprises a drive-side case portion 8 that covers the left-right end portion where the drive control unit 5 is located, and a main body-side case portion 7 that covers the portion excluding the portion covered by the drive-side case portion 8. The drive-side case portion 8 is provided in a state that it protrudes forward from the main body-side case portion 7. The partition body 11 arranged in the shutter case 6, which can be made compact in this way, is also configured to be narrow and located in the drive-side case portion 8, thus contributing to the compactness. Furthermore, since the partition body 11 is provided in a removable manner in this case, maintenance of components such as the winding body 4 and power transmission unit 5c, which are located behind (rear of) the partition body 11, can be easily performed. And when the partition body 11 is configured to be removable in this way, the removal position of the partition body 11 is set so that the upper and lower edges 11a and 11b are located in front of the axis position 4a of the winding body 4, so that the partition body 11 can be removed from the front part of the winding body 4, making maintenance work easier.

[0030] On the other hand, even if the partition body 11 is configured such that its upper edge 11a is detachably attached to the rear portion above the lintel portion 6a of the shutter case 6, as in the second embodiment, and its lower edge 11b is detachably attached to the front of the axis position 4a of the winding body 4, the attachment and detachment of the partition body 11 becomes easier, simplifying maintenance work. In this configuration where the partition body 11 is detachable, the partition body 11 can be composed of left and right divided partition plates 11x, 11y, and 11z, and each of these can be individually removed. In this case, when performing maintenance on components behind the partition body 11, such as the winding body 4, it is possible to remove the partition plates 11x, 11y, and 11z of the part to be maintained, thereby improving work efficiency.

[0031] Furthermore, the partition 11 does not have to be detachable as in the first and second embodiments described above, but can be made of a sliding type. For example, as in the third embodiment, the partition 11 can be configured to move freely in the left-right direction so that part or all of the area covered by the partition 11 can be opened. When it is necessary to perform maintenance on the member behind the partition 11, the partition 11 can be moved inward in the left-right direction towards the main body case 7, opening all or part of the area that was partitioned by the partition 11, thereby improving work efficiency. In this case, the partition 11, which moves in the left-right direction and becomes open, overlaps with the front plate 7b of the main body case section 7. As a result, the partition 11 in its open position is stored within the main body case section 7, eliminating the need to secure a separate storage space.

[0032] When the partition body 11 is made movable in this way, it can be configured to be movable in the front-to-back direction, as in the fourth embodiment, rather than being configured to be movable in the left-to-right direction as in the third embodiment. This allows the partition body 11 to be opened and closed by effectively utilizing the space on the outer periphery of the shutter curtain 3 wound around the winding body 4. [Industrial applicability]

[0033] This invention can be used as a building shutter device installed to open and close openings such as entrances to buildings. [Explanation of symbols]
