[0008] This embodiment discloses the following features. The first feature is an opening / closing device comprising an opening / closing body that performs a closing operation by dividing a space, a guide rail that guides the widthwise end of the opening / closing body in the closing direction, and an opening / closing body storage section that stores the opening / closing body on its opening direction side, wherein an opening / closing auxiliary device for operating the opening / closing body is provided within the opening / closing body storage section, and a storage member is provided on the outer surface of the guide rail, extending the internal space in the opening / closing body opening direction and communicating with the opening / closing body storage section, and a signal transmission member is provided inside the storage member that guides a mechanical or electrical wired signal in the opening direction and transmits it to the opening / closing auxiliary device, and a signal generating device is connected to the signal source side of the signal transmission member and generates the wired signal, and an opening that can pass the signal generating device is provided in the side wall of the storage member so as to be able to open and close (see Figures 1 to 4). With this configuration, the simple structure can prevent the opening and closing body from interfering with the signal transmission member and the signal generating device, and the opening of the accommodating member can be opened to easily perform maintenance on the signal transmission member and the signal generating device.

[0009] The second feature is that, in order to further improve maintainability, the housing member is attached along the outer surface of one side of the guide rail in the thickness direction of the opening / closing body (see FIG. 3).

[0010] The third feature is that, in order to further improve maintainability, the opening is provided continuously from at least a position including the signal generating device to the opening / closing body housing portion (see FIG. 4).

[0011] The fourth feature is a specific embodiment with good maintainability, in which a cover member that closes the opening in an openable and closable manner is provided on the storage member, and the cover member has, at one end side in the width direction of the opening / closing body, an engaging piece portion that fits into the storage member in a concave and convex manner, and at the other end side in the width direction of the opening / closing body, a fastening piece portion that is fastened to the storage member by a detachable fastener (see Figures 3, 5 and 7).

[0012] A fifth feature is that the opening / closing auxiliary device includes an opening / closing machine that transmits power from an electric drive source to the opening / closing body to drive it to open or close, the opening / closing machine is provided with a manual switching device that cuts off the power transmission path of the electric drive source by pulling an operating unit, making it possible to manually open or close the opening / closing body, the signal transmission member is a linear member that has one end attached to the operating unit and the other end connected to the signal generating device, and the signal generating device constitutes a manual switching operating unit that pulls the other end of the linear member by mechanically operating an operating lever (see FIGS. 1 to 4). Here, the "linear member" does not refer to a member (such as an electric wire) whose sole purpose is to transmit electrical wired signals, but rather to a member that is mechanically pulled (including, for example, a metal wire, a resin wire, a string-like member, a chain-like member, etc.). Furthermore, the "linear member" may be a hard linear member such as a rod-shaped member in addition to the flexible linear member described above. Specific examples of this include a configuration using a single rod-shaped member, a configuration in which multiple rod-shaped members are linked together, and a configuration in which a rod-shaped member is connected to a flexible linear member. Furthermore, the "mechanical operation" includes, for example, a rotation operation, a slide operation, a push operation, a pull operation, and the like.

[0013] The sixth feature is that the opening / closing auxiliary device comprises an opening / closing machine that transmits power from an electric drive source to the opening / closing body to drive it to open and close, and a control unit that controls the opening / closing machine, the signal transmission member being an electric wire having one end electrically connected to the control unit and the other end electrically connected to the signal generating device, and the signal generating device constituting an obstacle detection sensor that detects obstacles in a non-contact manner using an obstacle detection medium that is emitted in the width direction of the opening / closing body (see Figures 1 to 4). Here, the "electric wire" does not refer to a component (such as a wire) intended solely for the transmission of mechanical signals, but rather to a component (such as a signal cable wire) that transmits signals by transmitting electrical wired signals.

[0014] The seventh feature is an installation structure of an opening and closing device that is easy to maintain and has good security, in which the guide rail is fixed to the indoor wall surface of the structure body, and the housing member is fixed to the indoor surface of the guide rail with the opening facing the indoor side (see Figure 3).

[0015] <First embodiment> Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings. In the following description, "thickness direction of the opening / closing body" refers to the thickness direction of the opening / closing body in the closed state. Also, "width direction of the opening / closing body" refers to a direction that is approximately perpendicular to the opening / closing direction of the opening / closing body, but is not the thickness direction of the opening / closing body. Also, "opening / closing direction of the opening / closing body" refers to the direction in which the opening / closing body slides to separate or open a space.

[0016] The opening and closing device 1 comprises an opening and closing body 10 that performs closing operation to separate a space, an opening and closing body storage section 20 that stores the opening and closing body 10 on the opening side, and left and right guide rails 30, 30 that guide both ends of the opening and closing body 10 in the closing direction, and is fixed to the indoor wall surface of a structural body A of a building or the like, as shown in Figure 3.

[0017] The opening / closing body 10 comprises an opening / closing body main body 11 formed by connecting a plurality of slats 11a, each formed by bending a horizontally elongated, approximately rectangular metal plate, so that the slats 11a can rotate between adjacent slats 11a, 11a, one above the other. A fixed seat plate 12 is connected to the lower end of the opening / closing body main body 11, and a movable seat plate 13 is connected to the lower end of the fixed seat plate 12 so that it can move in the vertical direction relative to the fixed seat plate (see Figure 1). Other examples of this opening / closing body 10 include a single or multiple panels, sheet-like materials, or net-like materials arranged in the opening / closing direction, or an appropriate combination of slats, panels, pipes, sheet-like materials, net-like materials, etc.

[0018] As shown in Figure 1, the opening / closing body storage section 20 is provided with an opening / closing auxiliary device 22 for causing the opening / closing body 10 to function (for example, opening / closing operation, stopping, etc.) inside a storage case 21 having an opening at the bottom for allowing the opening / closing body 10 to appear and disappear.

[0019] According to one example of this embodiment, the opening / closing auxiliary device 22 includes a winding shaft 22a that is rotatably supported within the storage case 21 and winds and unwinds the opening / closing body 10, an opening / closing mechanism 22b that drives and rotates the winding shaft 22a to open and close the opening / closing body, and a control unit 22c that controls the operation of the opening / closing mechanism 22b in accordance with input signals, etc.

[0020] The opening / closing device 22b is a mechanism that adjusts the rotation of an electric drive source (for example, an electric motor) to an appropriate rotational force and rotational speed using a gear mechanism and outputs the rotation from the output shaft 22b1. The rotation of the output shaft 22b1 is transmitted to the winding shaft 22a via a power transmission mechanism such as a chain and a sprocket. The opening / closing device 22b is provided with a manual switching device (not shown) that cuts off the power transmission path of the electric drive source when the operating part 22d is pulled, thereby enabling manual opening and closing of the opening / closing body 10. This manual switching device is configured with a well-known clutch mechanism or the like, and when the operating part 22d is pulled, the pulling force disconnects the output shaft 22b1 from the electric drive source to set it in a free state, and when the signal transmission member w1 (linear member) is loosened, the biasing force of a biasing member (not shown) connects the output shaft 22b1 to the electric drive source to enable power transmission.

[0021] The control unit 22c is an electronic circuit equipped with, for example, a microcomputer, and functions according to a pre-stored program to process signals from a signal generating device s2 (obstacle detection sensor) described later and an operation switch (not shown), and controls the opening / closing device 22b according to the processing results.

[0022] The opening / closing device 22b and the control unit 22c configured as described above are disposed closer to the signal generating devices s1 and s2 in the width direction of the opening / closing body. This arrangement allows the signal transmission members w1 and w2 to be relatively short, and also makes it easier to maintain the opening / closing device 22b, the control unit 22c, the signal transmission members w1 and w2, and the signal generating devices s1 and s2, etc., because they are concentrated on one side in the width direction of the opening / closing body.

[0023] The guide rail 30 is a long member that surrounds the end of the opening / closing body 10 in the width direction in a concave shape and extends in the up-down direction (see FIGS. 2 and 3). On the outer surface of this guide rail 30, there are provided a support member 40 that immovably supports the guide rail 30, and a long, hollow accommodating member 50 whose internal space extends in the opening direction of the opening / closing body and communicates with the inside of the accommodating case 21 of the opening / closing body accommodating section 20. A cover member 60 is attached to the accommodating member 50. The guide rail 30, the support member 40, the housing member 50 and the cover member 60 are provided symmetrically with the opening / closing body 10 interposed therebetween (see FIG. 3).

[0024] As shown in Figure 5, the guide rail 30 is formed with a generally concave cross section and is made up of an opening wall portion 31 having an opening for inserting the end portion of the opening / closing body 10, a generally flat wall portion 32 provided on one side in the thickness direction of the opening / closing body, an engaging wall portion 33 provided on the other side in the thickness direction of the opening / closing body, and a connecting wall portion 34 connecting these wall portion 32 and engaging wall portion 33 on the opposite side of the opening wall portion 31 in the width direction of the opening / closing body.

[0025] The engaging wall portion 33 has a fastening piece portion 33a and an engaging piece portion 33b protruding from its outer surface.

[0026] The fastening piece 33a is a part that protrudes outward in the thickness direction of the opening / closing body in a flat plate shape on the opening wall portion 31 side in the width direction of the opening / closing body (see Figure 5), and is used to insert a removable fastening device M (e.g., a screw, bolt, etc.).

[0027] The engaging piece 33b projects outward in the thickness direction of the opening / closing body on the connecting wall 34 side in the width direction of the opening / closing body, and has an L-shaped cross section (see FIG. 5).

[0028] In FIG. 5, reference numeral 31a denotes a fitting recess for fitting and attaching a cushioning material, an airtight material, or the like.

[0029] The support member 40 is a long member that continues along the outdoor side of the guide rail 30 in the opening and closing direction of the opening and closing body, and is attached to the inner wall surface of the structure body A by bolts, anchors, brackets, etc., as shown in Figure 3.

[0030] The housing member 50 is a long member that continues in the opening and closing direction of the opening and closing body along the indoor side of the guide rail 30, and is fastened to the indoor side of the guide rail 30 with fasteners such as rivets.

[0031] According to a preferred example of this embodiment, the support member 40 and the accommodating member 50 are formed from members X of different lengths and the same cross-sectional shape. That is, the support member 40 and the accommodating member 50 can be formed by cutting a single elongated member X to a predetermined length. As an example other than the illustrated example, the support member 40 and the accommodating member 50 can also be made to have the same length and be made into a common part.

[0032] As shown in Figure 6, the member X is formed into a generally concave cross section with an opening x4 in the side wall, consisting of two generally parallel wall portions x1 and x2 spaced apart and a connecting wall portion x3 that connects these wall portions x1 and x2 at one end side in the thickness direction of the opening / closing body. One wall portion x1 has a thick-walled fastening piece portion x11 on the opening x4 side in the thickness direction of the opening / closing body for fastening by screwing a fastener M such as a screw or a bolt. The other wall portion x2 has a protruding engagement piece x21 facing the inside of the opening x4.

[0033] The opening x4 is formed to a size that allows passage of two types of signal generating devices s1 and s2 and signal transmission members w1 and w2, which will be described later. More specifically, the dimension of this opening x4 in the width direction of the opening / closing body is set to be larger than that of the signal generating devices s1 and s2, and it is provided in an elongated shape that continues from a position including the signal generating devices s1 and s2 to the storage case 21 (see FIG. 4).

[0034] 4, the reference symbol P denotes a plate-shaped partition provided as needed. This partition P separates the space on the signal transmission member w1 side from the space on the signal transmission member w2 side within the housing member 50, and prevents the signal transmission member w1 (linear member) from interfering with the signal transmission member w2 (signal wire).

[0035] The engaging piece portion x21 is a portion that fits in a concave and convex manner with the engaging piece portion 33b of the guide rail 30 or the engaging piece portion 63 of the cover member 60, and protrudes flatly toward the inside of the opening x4 in the width direction of the opening / closing body (see Figure 6).

[0036] The support member 40 is arranged along the outer surface of one side of the guide rail 30 in the thickness direction of the opening / closing body (the outdoor side in the illustrated example) (see Figure 3), and has a length that covers approximately the entire length of the guide rail 30 in the vertical direction (see Figure 2). The support member 40 has a connecting wall portion x3 (see FIG. 6) fixed to the inner wall surface of the structure body A by means of bolts, anchors, brackets, etc. (see FIG. 3).

[0037] The lower end of the storage member 50 is disposed midway along the guide rail 30 (see FIG. 2), and the upper end is disposed so as to contact the storage case 21. The internal space of the storage member 50 extends continuously in the opening direction and communicates with the space within the storage case 21. The housing member 50 is attached along the outer surface of one side of the guide rail 30 in the thickness direction of the opening / closing body, with the opening x4 facing indoors. More specifically, the housing member 50 has a connecting wall x3 (see FIG. 6) fixed to the wall 32 (see FIG. 5) of the guide rail 30 by fasteners (e.g., screws, bolts, rivets, etc.) (see FIG. 3).

[0038] Inside this accommodating member 50, there are provided two types of signal transmission members w1 and w2 that guide mechanical or electrical wired signals in the opening direction and transmit them to the opening / closing auxiliary device 22, and two types of signal generating devices s1 and s2 that are connected to the signal source sides of these signal transmission members w1 and w2 and emit mechanical wired signals and electrical wired signals. The opening x4 of the housing member 50 is closed by a cover member 60 so as to be openable and closable.

[0039] The cover member 60 is a member having a generally concave cross section as shown in Fig. 7, and has an engaging piece 63 at one end in the width direction of the opening / closing body of a flat cover main body 61, and a fastening piece 62 at the other end. The engaging piece 63 of this cover member 60 is fitted in a concave and convex manner with the engaged piece x21 (see Fig. 6) of the accommodating member 50, and the fastening piece 62 is overlapped with the fastened piece x11 (see Fig. 6) of the accommodating member 50, and this overlapping portion is fastened by a detachable fastener M (such as a bolt or a screw).

[0040] The fastening piece 62 is formed in a flat plate shape that protrudes from the cover main body 61 in the thickness direction of the opening / closing body (see FIG. 7). In addition, the engaging piece portion 63 is formed in a concave cross section with an opening facing the opposite side of the fastening piece portion 62 in the width direction of the opening / closing body, and the engaging piece portion x21 (see Figure 6) of the storage member 50 is fitted inside the concave portion.

[0041] One of the signal generating devices s1 constitutes a manual switching operation unit that enables manual opening and closing of the opening-closing body 10 by transmitting a mechanical signal. More specifically, the signal generating device s1 pulls the lower end side of the signal transmission member w1 (linear member) by mechanically operating the operation lever s11 to rotate, and this pulling operation cuts off the power transmission path of the opening-closing device 22b (in other words, releases the manual switching device described above), thereby enabling the opening-closing body 10 to be opened and closed manually.

[0042] One end of the operating lever s11 in the vertical direction is pivotally supported on the housing member 50 via a bracket or the like.

[0043] The signal transmission member w1 is a flexible, long, linear member (including metallic and non-metallic wires), one end of which is attached to the operating part 22d of the opening / closing mechanism 22b, and the other end of which is attached to the rotating part of the operating lever s11.

[0044] The other signal generating device s2 is an obstacle detection sensor (e.g., a photocell sensor) that detects obstacles in a non-contact manner by emitting an obstacle detection medium in the width direction of the opening / closing body. More specifically, this signal generating device s2 has a transmitter s21 that emits an obstacle detection medium such as infrared light, and a capture unit s22 that captures the obstacle detection medium.

[0045] The signal transmission member w2 is a signal wire whose one end is electrically connected to the capture portion s22, and whose other end is extended upward and further extended laterally within the storage case 21 and electrically connected to the control portion 22c.

[0046] The signal generating device s1, the capturing portion s22, and the signal transmitting members w1 and w2 are provided only in one of the left and right housing members 50 (the right housing member in FIG. 3). The transmitter s21 and its power supply wiring w2' are housed in the other (left side in FIG. 1) housing member 50. The power supply wiring w2' extends upward and is electrically connected to a power supply circuit (not shown) in the opening / closing body housing portion 20.

[0047] Next, the characteristic functions and effects of the opening and closing device 1 having the above configuration will be described in detail. According to the opening and closing device 1, the signal generating devices s1, s2 and the signal transmitting members w1, w2, etc. are provided in a housing member 50 that is separate from the guide rail 30. This prevents the width direction ends of the opening and closing body 10 from interfering with the signal generating devices s1, s2 and the signal transmitting members w1, w2, etc.

[0048] Furthermore, when repairing or replacing the signal generating devices s1 and s2, removing the cover member 60 opens the opening x4 in a long, upward direction (see Figure 4), so that the signal generating devices s1 and s2 and the signal transmission members w1 and w2, etc., inside the accommodating member 50 can be easily removed by passing them through the opening x4.

[0049] In particular, according to a preferred example of this embodiment, as shown in Figure 3, a guide rail 30 is fixed to the inner wall surface of the structure body A via a support member 40, and a storage member 50 and a cover member 60, etc. are arranged on the indoor side of the opening / closing body 10 fitted into this guide rail 30, so that in addition to good ease of attachment and detachment of the signal generating devices s1, s2 and the signal transmission members w1, w2, etc., it also has excellent protection against criminal acts from the outdoors.

[0050] <Second embodiment> Next, the opening and closing device 2, the cross section of which is shown in FIG. 8, will be described. The opening and closing device 2 does not include the housing member 50 and the cover member 60 from the opening and closing device 1, and uses the support member 40 as a housing member for housing signal generating devices s1, s2 and signal transmission members w1, w2, etc., and is installed on the outdoor side of the structure body A.

[0051] The support member 40 accommodates signal generating devices s1, s2 and signal transmission members w1, w2, etc., in the same manner as the accommodation member 50, and its opening x4 faces the outdoors, and its connecting wall portion x3 is fixed to the outer wall surface of the structure body A by bolts, anchors, brackets, etc.

[0052] In this opening and closing device 2, the guide rail 30 is fastened by a removable fastener M, with the engaging piece portion 33b fitted into the engaged piece portion x21 of the support member 40 so as to cover the opening x4 of the support member 40, and the fastening piece portion 33a overlapping the fastening piece portion x11 of the same support member 40. Therefore, by removing the guide rail 30, the opening x4 of the support member 40 can be opened, and maintenance work on the signal generating devices s1, s2 and the signal transmitting members w1, w2 inside the support member 40 can be easily performed. Moreover, under normal circumstances, the support member 40 as a storage member is positioned closer to the interior than the guide rail 30 and the opening / closing body 10, providing good security against crime.

[0053] <Third embodiment> Next, the opening and closing device 3, the cross section of which is shown in FIG. 9, will be described. The opening and closing device 3 is provided on the indoor side of the structure body A by omitting the support member 40 from the opening and closing device 1 (see FIG. 3) and replacing the guide rail 30 with a guide rail 30'.

[0054] The guide rail 30' is obtained by removing the fastening piece 33a and the engaging piece 33b (see FIG. 5) from the above-mentioned guide rail 30'. This guide rail 30' is fastened and fixed directly to the indoor side surface of the structure body A without using the above-mentioned support member 40.

[0055] Therefore, according to the opening and closing device 3 shown in Figure 9, almost all of the components that make up the opening and closing device 3 are located on the indoor side of the wall surface of the structure body A, and further, the storage member 50, cover member 60, fastening device M, etc. are arranged on the indoor side of the opening and closing body 10 that is fitted into the guide rail 30', so that it has better defensive properties against criminal acts, etc. from the outdoors.

[0056] <Other variations> According to the above embodiment, the opening / closing auxiliary device 22 is constituted by the winding shaft 22a, the opening / closing device 22b, the control unit 22c, etc., but the opening / closing auxiliary device 22 can be constituted by devices other than those shown in the drawings. For example, the opening / closing auxiliary device 22 may be a brake mechanism that restrains the opening / closing device 22b, and a signal generating device and a signal transmitting member that transmit a mechanical or electrical wired signal to this brake mechanism may be provided.

[0057] Other examples of the signal generating device and the signal transmitting member include a multi-optical axis sensor that detects obstacles using multiple light paths and its electrical wiring, or an open / close stop switch that transmits an open / close signal or a stop signal to the opening / closing auxiliary device 22 and its electrical wiring.

[0058] Furthermore, particularly from the viewpoint of security, it is preferable to provide the storage member 50 on the indoor side of the guide rail 30, as in the illustrated example, but other examples include a configuration in which the storage member 50 is provided on the outside of the guide rail 30 in the width direction of the opening / closing body, or a configuration in which the storage member 50 is provided on the outdoor side of the guide rail 30.

[0059] In addition, in the above embodiment, a storage member 50 is provided on each of the guide rails 30, 30 on both sides of the opening / closing body in the width direction, but as another example, it is also possible to provide a storage member 50 on only one of the guide rails 30. In this other example, a mechanical signal transmission member w1 and a signal generating device s1 may be provided in the housing member 50 provided on only one side. When an electrical signal transmission member w2 and a signal generating device s2 are provided, for example, the capturing portion s22 may be provided inside only one of the housing members 50, and the transmitting portion s21 may be provided on the guide rail 30 on the other side. Furthermore, as another example, the signal generating device s2 may be configured as a reflective photoelectric sensor having a light emitting and receiving portion on only one side, and this signal generating device s2 may be provided in only one of the housing members 50.

[0060] Furthermore, the present invention is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the present invention. [Explanation of symbols]
