According to a fourteenth aspect of the present invention, there is provided the greenhouse driving device according to the thirteenth aspect, wherein the operation target member is a house window of a greenhouse.

  According to the present invention, in a state where the first engaged portion is engaged with the engaging portion of the actuator, the temperature in the greenhouse rises so that the driving material expands and the piston moves relative to the cylinder. When the movement member is relatively extended, the traveling member moves in one direction along the support frame, and the operation target member connected via the arm is automatically released as the temperature changes. In a state where the temperature is lowered and the driving material is contracted, the traveling member operates in the opposite direction to the above and closes the operation target. On the other hand, in a state where the engagement between the first engaged portion and the engaging portion of the actuator is released, the traveling member can be manually moved along the support frame by the manual operation means. By engaging the engaging portion with the engaging portion provided on the support frame, the position of the traveling member on the support frame can be fixed. That is, according to the present invention, it is possible to easily switch between the automatic operation mode and the manual operation mode only by selecting whether or not the first engaged portion is engaged with the engaging portion of the actuator. And can be manufactured at a lower cost than conventional ones.

  Further, since the lock plate is urged by the elastic member in the direction in which the lock plate is pressed toward the support frame, the first engaged portion is engaged with the engagement portion of the actuator or the engagement portion of the support frame. The elastic force of the elastic member functions in the direction in which the engaged state is maintained. As a result, when the first engaged portion is engaged, no large flapping occurs regardless of whether the operation target member is swung in the closing direction or the opening direction due to wind or the like. Further, the piston or cylinder constituting the actuator is always urged in the direction to return to the initial state by the return elastic member, and the first engaged portion of the lock plate is engaged with the engaging portion of the actuator. It has a possible configuration. For this reason, in a state where the first engaged portion of the lock plate is engaged with the engaging portion of the actuator, the operation target member includes the first engaged portion of the lock plate and the engaging portion of the actuator. Therefore, the elastic member for return is always urged in the closing direction. In the automatic operation mode by the actuator, in order to prevent fluttering due to wind or the like, in Patent Document 1, in addition to the return elastic member for returning the piston or cylinder to the initial state, it is directly connected to the operation target member to prevent flapping. However, according to the present invention, in addition to the function of the return elastic member to return the piston or cylinder to the initial state as described above, the function of preventing the fluttering of the operation target member is also provided. Therefore, there is an advantage that the structure is simplified. Further, during manual operation, the engagement between the first engaged portion of the lock plate and the engaging portion of the actuator is released, so that the elastic force of the return elastic member does not function and is lighter than before. The operation target member can be operated with force.

  Moreover, in the aspect which forms the 1st to-be-engaged part with the 1st and 2nd lock plate which consists of another member, there exist the following effects other than an above-described effect. That is, the second lock plate is pivotally supported independently of the first lock plate so that the tip protrudes downward from the upper protruding piece of the first lock plate. It is urged by an elastic member, and the manual operation means is connected to the second lock plate. Accordingly, when the manual operation means is operated while the first engaged portion is engaged with the engaging portion provided in the actuator, the tip of the second lock plate is tilted backward, and the engaging portion and The engagement state is automatically released. For this reason, switching from the automatic operation mode in which the first engaged portion is engaged with the engaging portion of the actuator to the manual operation mode is further facilitated.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings. FIGS. 1-6 is a figure which shows the drive device 1 for greenhouses concerning the 1st Embodiment of this invention. As shown in this figure, the greenhouse driving device 1 of the present embodiment has an actuator 10, a support frame 20, a traveling member 30, an arm 40, a lock plate 50, a manual operation means 60, and a return elastic member 70. Configured.

  The actuator 10 includes a cylinder 11 and a piston 12 that is slidably disposed in the cylinder 11, and a driving material (not shown) that changes in volume in response to temperature is O-ring in the cylinder 11. It is sealed and filled via a sealing member such as. As the driving material, for example, a liquid such as alcohol or glycerin or a gas such as air can be used. When the volume of the driving material expands due to a temperature rise, the piston 12 is pressed in the cylinder 11 and extends. . The outer surface of the cylinder 11 is preferably colored black. The solar heat absorbability is improved, and the heat radiation action during cloudy weather is fast, so that the responsiveness to temperature changes can be enhanced. As shown in FIGS. 1 and 2, only one actuator 10 may be used. For example, a female thread portion is formed at the rear end portion of the cylinder 11, and a male thread portion is formed at the piston tip portion of another actuator. For example, a plurality of actuators may be connected in series. As a result, a larger amount of movement of the movement target member can be secured, and the movement target member can be used with an appropriate number of connections depending on the type of movement target member.

  Further, as described above, the actuator 10 expands the driving material filled in the cylinder 11 when the temperature rises, and the position of the piston 12 changes. Even if is contracted, the piston 12 does not return promptly. Therefore, a return elastic member 70 for quickly returning the piston 12 when the drive material contracts is provided. The return elastic member 70 only needs to be able to be pressed against the piston 12 in the direction of being accommodated in the cylinder 11, and the attachment position and structure thereof are not limited. For example, a coil spring can be disposed on the outer periphery of the cylinder 11 so that one end is connected to the piston 12 and the other end is connected to the cylinder 11. However, as in the present embodiment, the return elastic member 70 made of a compression coil spring is arranged in series with the actuator 10 in the support frame 20 described later, and one end of the elastic member 70 comes into contact with one end of the support frame 20, The other end is preferably provided so as to abut on the movable side of the cylinder or piston (in this embodiment, the head portion of the piston 12). Since it only needs to be accommodated in the support frame 20 in series with the actuator 10, the component configuration necessary for the arrangement is simplified, and a member having a strong elastic force can be arranged as the return elastic member 70. It is possible to prevent the piston 12 from extending by resisting the elastic force of the return elastic member 70 when it is beaten by wind or the like.

  The support frame 20 is formed in a long substantially cylindrical shape (substantially rectangular tube shape) capable of accommodating the actuator 10 and the return elastic member 70 described above. The support frame 20 is provided by being fixed to an appropriate stationary part of a greenhouse suitable for moving a target operation target member, for example, a frame material supporting a plastic film or a glass plate. In the present embodiment, in order to open and close the greenhouse window 100 as an operation target member, one end of the support frame 20 is fixed near the upper portion 111 of the window frame 110 located on the base end 101 side of the window 100, The other end is fixed by an attachment member 113 provided near the lower portion 112 of the window frame 110. The attachment member 113 has a predetermined length, one end is fixed in the vicinity of the lower portion 112 of the window frame 110, and the other end protrudes on the opposite side to the separation / operation direction of the window 100, that is, inside the greenhouse. The other end of the support frame 20 is fixed to the other end of the mounting member 113. As a result, the support frame 20 is inclined so as to extend from one end portion toward the other end portion in a direction away from the window frame 110 and in a direction opposite to the separation direction on the other end 102 side of the end window 100. Arranged. The support frame 20 does not necessarily need to be disposed at an inclination, but in the present embodiment, the support frame 20 is configured to be opened while pressing the wife window 100 by an arm 40 described later, and therefore the support frame 20 is disposed at an inclination. Thus, while having a simple configuration, there is an advantage that the opening angle of the wife window 100 by the arm 40 can be increased. Of course, depending on the shape of the arm 40 and the like, the support frame 20 can be arranged substantially vertically.

  On two opposing side surfaces of the support frame 20, slit-like hole portions 21 having a predetermined length are formed along the longitudinal direction of the support frame 20. The actuator 10 accommodated in the support frame 20 is provided with a cylinder 11 fixed to the support frame 20, and constitutes an engaging portion in a direction perpendicular to the piston 12 at the head portion of the piston 12. An engagement pin 12a is provided. The engagement pin 12a is disposed so as to protrude outward from the hole 21 formed in the support frame 20, and the engagement pin 12a moves in the hole 21 as the piston 12 expands and contracts. To do.

  Further, of the two side surfaces of the support frame 20, an engagement pin for full opening, which is two engagement portions that protrude outward from the side surface nearer the upper edge (one end portion) than the upper edge of the hole portion 21. 23 is provided.

  The traveling member 30 is provided so as to be movable along the longitudinal direction of the support frame 20 as shown in FIGS. 1 to 3, and has two side plate members 31, 31 facing each other. A plurality of wheels 32 to 35 are disposed between 31 with the support frame 20 interposed therebetween. Specifically, the first and second wheels 32 and 33 are disposed near the window frame 110 with the support frame 20 interposed therebetween, and the third and fourth wheels 34 and 35 are disposed on the opposite side, and are supported. The vehicle can travel along the frame 20. It should be noted that in order to prevent derailment when traveling along the support frame 20 and to ensure stable travel so as not to be swayed from side to side, support is provided on the side where the third and fourth wheels 34 and 35 are in contact. The side surface of the frame 20 is preferably protruded toward the third and fourth wheels 34 and 35 so that the third and fourth wheels 34 and 35 travel between the protruding walls 22 (FIG. 4). And FIG. 6). A rotation shaft 38 for supporting one end of the arm 40 is provided between the third wheel 34 and the fourth wheel 35. The arm 40 is made of a long plate-like member, and the other end is pivotally supported near the proximal end portion 101 of the end window 100 as an operation target member. Therefore, when the traveling member 30 moves upward along the support frame 20, the arm 40 protrudes outward from the greenhouse. Therefore, the wife window 100 connected thereto is opened, and the traveling member 30 is supported. When moving downward along the frame 20, the wife window 100 is closed.

  A lock plate 50 is supported on the traveling member 30. The lock plate 50 is disposed such that the base end portion is pivotally supported by the side plate members 31, 31 between the first and second wheels 32, 33 of the traveling member 30. As shown in FIGS. 3 and 4, the lock plate 50 connects the side plates 51, 51 to the two side plates 51, 51 that face each other with a gap slightly wider than the width of the support frame 20. The rear plate 52 is integrally formed, and the lower portions 51 a and 51 a of the side plates 51 and 51 are base end portions that are pivotally supported by the side plate members 31 and 31 of the traveling member 30. Near the other end (near the upper part) of the side plates 51, 51 is provided with an upper projecting piece 51e and a lower projecting piece 51f projecting to the front end edge located on the support frame 20 side, and the groove between them is the first groove. This is the engaged portion 51b. The first engaged portion 51b can be engaged with the engagement pin 12a of the actuator 10 or the full-open engagement pin 23 provided on the support frame 20. In addition, a second notch formed in a concave shape is formed on the rear edge of the side plates 51, 51 on the side of the window frame 110, that is, on the edge opposite to the formation position of the first engaged portion 51b. An engaged portion 51c is formed. The second engaged portion 51c engages with a full-close engagement pin 103 that is an engagement portion for forced locking provided near the lower end of the wife window 100 in the fully-closed state of the window 100, It fulfills the function of maintaining the fully closed state (see FIG. 2).

  The lock plate 50 is urged by an elastic member in a direction approaching the support frame 20. By being biased in the direction approaching the support frame 20, the first engaged portion 51 b is engaged with the engagement pin 12 a of the actuator 10 or the fully open engagement pin 23 provided on the support frame 20. Combined. Thereby, even if the both ends are engaged, even if the wife window 100 is beaten by wind or the like, it is possible to prevent the engagement state from being released. When a force is applied in the direction of closing the window 100 due to wind or the like, the upper protruding piece 51e forming the first engaged portion 51b comes into contact with the engaging pin 12a or the fully opening engaging pin 23, When a force is applied in the opening direction, the lower protruding piece 51f forming the first engaged portion 51b abuts on the engaging pin 12a or the fully opening engaging pin 23 to maintain the engaged state. . The elastic member is not particularly limited as long as it has such a function, but in the present embodiment, the first spring is provided penetrating above the lower portions 51a and 51a serving as the base end portions of the side plates 51 and 51 of the lock plate 50. And the second spring pin member 36 disposed between the side plate members 31 and 31 of the traveling member 30 and below the lower portions 51a and 51a of the lock plate 50. The tension coil spring 55 arranged in the above is used as the elastic member. As shown in FIG. 4, when the first engaged portion 51 b is engaged with the engagement pin 12 a of the actuator 10, the first spring pin member 53 is second when viewed from the side. The spring pin member 36 is located closer to the support frame 20 than the spring pin member 36.

  As a result, as shown in FIG. 6, when the rotation angle of the lock plate 50 is located closer to the support frame 20 than the switching point as a boundary, the lock plate 50 is supported by the tension coil spring 55. When it is positioned closer to the window frame 110 than the switching point as a boundary, the tension coil spring 55 engages with the direction of the window frame 110, that is, the engagement pin 103 for full closure. Will be biased in the direction. Therefore, according to the tension coil spring 55 of the present embodiment, the elastic force for engaging the engaging pin 12a of the actuator 10 and the engaging pin 23 for full opening of the support frame 20 and the wife provided in the opposite direction. Both the elastic force for engaging with the full-close engagement pin 103 of the window 100 can be made to function as a single member with the switching point as a boundary.

  The manual operation means 60 operates the traveling member 30 along the support frame 20 in a state where the engagement of the lock plate 50 with the engagement pin 12a of the actuator 10 is released. In the present embodiment, a substantially U-shaped plate member 61 and a traction string member 62 are provided. The plate member 61 includes two side plate portions 61a and 61a provided opposite to each other, and a connecting plate portion 61b that connects the side plate portions 61a and 61a, and the open ends of the side plate portions 61a and 61a are The travel member 30 is pivotally supported independently of the lock plate 50 so as to be rotatable. The tow string member 62 is connected to the connecting plate portion 61 b of the plate member 61. More specifically, the plate member 61 is pivotally supported by the same shaft member 37 as the lower portion 51a of the lock plate 50 with respect to the traveling member 30 as shown in FIG. The spring pin member 53 is disposed closer to the window frame 110 than the spring pin member 53, and can contact the first spring pin member 53.

  The other end side of the pulling string member 62 having one end connected to the connecting plate portion 61b extends upward along the support frame 20 as shown in FIG. 1 and FIG. It is hung down below the pulley member 120 provided on the upper part of the window frame 110 to which the portion is fixed. Accordingly, when the operation portion 62a provided at the other end is pulled downward, the plate member 61 is pulled upward. At this time, when the first engaged portion 51b of the lock plate 50 is disengaged from the engagement pin 12a of the actuator 10, the plate member 61 presses the first spring pin member 53 toward the support frame 20 side. Thus, the traveling member 30 rises along the support frame 20. Since the upper edge of the upper protruding piece 51e that forms the first engaged portion 51b of the lock plate 50 is a mountain-shaped inclined edge 51d, for example, as shown in FIGS. As described above, from the state where the lock plate 50 is positioned below the engaging pin 12a of the actuator 10, the operating portion 62a of the traction string member 62 is pulled and the first spring pin member 53 is pressed and lifted. After that, after the inclined end edge 51d comes into contact with the engaging pin 12a, and then the lock plate 50 is slightly rotated backward so that the relative position between the inclined end edge 51d and the engaging pin 12a is shifted, The first engaged portion 51b engages with the engagement pin 12a.

  The engagement state between the first engaged portion 51b and the engagement pin 12a of the actuator 10 or the full-open engagement pin 23 provided on the support frame 20 is as described above. Simply pulling the operating portion 62a downward does not release the plate member 61 because it pushes the lock plate 50 in the engaging direction via the first spring pin member 53. Therefore, the unlocking string member 56 is connected to the back plate 52 of the lock plate 50. When the lock release string member 56 is pulled and the lock plate 50 is slightly rotated to the window frame 110 side, the engaged state is released. Thereafter, the tow string member 62 is operated to support the traveling member 30. It can be operated along the frame 20.

  The greenhouse driving device 1 of the present embodiment operates as follows. When the indoor temperature of the greenhouse is equal to or lower than a predetermined temperature (for example, at night), the driving material filled in the cylinder 11 of the actuator 10 is not expanded, so the wife window 100 is in the position shown in FIG. Closed. In the closed state, when the unlocking string member 56 is pulled forward and the lock plate 50 is rotated by a predetermined angle toward the window frame 110, as shown in FIG. 2A, the second engaged portion 51c. Engages with the fully closing engagement pin 103 of the window 100 and is forcibly locked. At this time, since the second engaged portion 51c is pressed against the full-close engagement pin 103 by the elastic force of the tension coil spring 55, the closed state is maintained even when the window 100 is beaten by wind or the like. . The plate member 61 is pressed by the first spring pin member 53 when the lock plate 50 is engaged with the full-close engagement pin 103 and rotates together with the lock plate 50 toward the window frame 110. It has become a state.

  On the other hand, when the operation portion 62a of the pulling string member 62 is pulled downward, the plate member 61 tries to rotate toward the support frame 20, so that the first spring pin member 53 is pressed by the plate member 61, The lock plate 50 also rotates in the same direction, and then, as shown in FIGS. 5A to 5E, the inclined end edge 51d abuts on the engaging pin 12a, and the inclined end edge 51d and the engaging pin 12a And the lock plate 50 is slightly rotated backward, and then the first engaged portion 51b engages with the engagement pin 12a of the actuator 10 (FIGS. 5E and 1). (State of (a)). Then, it is pressed in the direction of the engagement pin 12 a by the elastic force of the tension coil spring 55.

  In this state, when the sun shines and the temperature in the greenhouse rises, the drive material in the cylinder 11 expands, and as shown in FIG. Let Since the first engaged portion 51 b of the lock plate 50 is engaged with the engagement pin 12 a of the actuator 10, when the piston 12 is extended, the traveling member 30 that supports the lock plate 50 is guided to the support frame 20. And move upwards. As the traveling member 30 moves upward, the position of one end of the arm 40 is displaced upward together with the traveling member 30, so that the other end of the arm 40 pushes the wife window 100 outward. It will be displaced. As a result, the wife window 100 is opened around the base end portion 101. In this state, when the temperature decreases and the driving material contracts, the piston 12 is pressed against the return elastic member 70, and the piston 12 is moved into the cylinder 11 by the weight of the window 100, contrary to the above. The wife window 100 is closed. Therefore, it is possible to automatically adjust the opening angle of the end window 100 without using a power source as the temperature changes. In addition, the elastic force of the return elastic member 70 causes the end window 100 to pass through the first engaged portion 51 of the lock plate 50 and the engagement pin 12a of the actuator 10 when they are engaged with each other. It also functions as a force for energizing in the closing direction. Accordingly, the return elastic member 70 suppresses the flare window 100 from fluttering due to wind or the like when the first engaged portion 51 and the engagement pin 12a are engaged in addition to the return operation of the piston 12. Also fulfills the function to do. As described above, the tension coil spring 55 also functions to prevent fluttering due to wind or the like. However, since the return elastic member 70 can have a larger elastic force than the tension coil spring 55, fluttering due to wind or the like can be used. The return elastic member 70 plays a larger role in prevention.

  When the manual operation is performed, first, the unlocking lace member 56 is pulled forward to release the engaged state between the first engaged portion 51 b and the engaging pin 12 a of the actuator 10. In this state, when the operating portion 62a of the tow string member 62 is pulled downward, as shown in FIG. 2 (b), regardless of the expansion / contraction state of the piston 12 of the actuator 10, that is, regardless of the temperature, The traveling member 30 can be moved above the support frame 20 to manually open the wife window 100. If the traction string member 62 is loosened, the traveling member 30 is attached to the support frame 20 by the weight of the wife window 100. It is possible to move downward along the window and close the wife window 100.

  When the operation part 62a of the tow string member 62 is pulled downward by manual operation and the end window 100 is opened, the inclined edge 51d of the lock plate 50 is provided on the support frame 20 when a predetermined position is reached. Further, the fully abutting engagement pin 23 comes into contact. In this state, when the pull-up is further lifted, the relative position of the fully open engagement pin 23 at the inclined end edge 51d is changed, the lock plate 50 is rotated slightly rearward, and the first engaged portion 51b is fully opened. (The state of FIG. 2B). In this manual operation, since the first engaged portion 51 of the lock plate 50 is not engaged with the engagement pin 12a of the actuator 10, the return elastic member that presses the piston 12 of the actuator 10 is used. It can be operated without receiving 70 elastic force. In the technique disclosed in Patent Document 1, the elastic member for applying the force for closing the window is attached separately from the elastic member for returning the piston, so that it is attached separately during manual operation. It had to be operated with a force sufficient to resist the elastic force of the elastic member. However, in the present embodiment, during manual operation, since the elastic force of the return elastic member 70 that applies the force for closing the window 100 is not received, the operation can be performed with a lighter force. However, since the elastic force of the tension coil spring 55 functions when engaged with the fully open engagement pin 23, the first engaged portion 51b is pressed against the fully open engagement pin 23 and fully opened. The state is more reliably maintained.

  As described above, according to the present embodiment, the first engaged portion 51b of the lock plate 50 is engaged with the engagement pin 12a of the actuator 10 or is released only from the engagement state. It is possible to easily switch between the automatic opening / closing mode and the manual operation mode. For this reason, it can be set as a simple structure conventionally, and manufacturing cost can also be reduced.

  7-12 is a figure which shows the drive device 1 for greenhouses concerning the 2nd Embodiment of this invention. In the greenhouse driving device 1 of the present embodiment, the configuration of the actuator 10, the support frame 20, the traveling member 30, the arm 40, and the return elastic member 70 is the same as that of the above embodiment, but in this embodiment, the actuator 10 Instead of the lock plate 50 of the first embodiment, the first lock plate 80 and the second lock plate 90 are used as members that engage with the engagement pins 12a and the front opening engagement pins 23 of the support frame 20. The difference is that the substantially U-shaped plate member 61 used as one of the manual operation means 60 of the first embodiment is not used. In these drawings, the same members as those in the first embodiment are denoted by the same reference numerals.

  Similar to the lock plate 50 of the first embodiment, the first lock plate 80 is urged by an elastic member in a direction approaching the support frame 20. Specifically, as shown in FIGS. 9 and 10, two opposing side plates (hereinafter referred to as “first side plates”) 81 and 81 and a back plate (hereinafter referred to as “first back surface”) connecting them. A first spring pin member 83 that is disposed above the lower portions 81 a and 81 a that are the base ends of the first side plates 81 and 81, and the first lock plate 80. Tension coil springs (hereinafter referred to as elastic members) between the second spring pin members 36 disposed below the lower plate portions 81a and 81a and between the side plate members 31 and 31 of the traveling member 30. , "First tension coil spring") 85.

  Due to such a configuration, the first lock plate 80 has the same rotation angle as that of the lock plate 50 of the first embodiment as shown in FIG. When it is positioned closer to the support frame 20 than that, it is urged by the tension coil spring 85 in the direction closer to the support frame 20, and when it is positioned closer to the window frame 110 than the switching point, the first The tension coil spring 85 biases in the direction of the window frame 110, that is, the direction of engaging with the full-close engagement pin 103.

  On the other hand, the first lock plate 80 has an upper protruding piece 81e protruding forward at the front edge near the upper portion of each first side plate 81, 81. The lower part of the piece 81e does not have a part corresponding to the lower protruding piece 51f provided on the lock plate 50 of the first embodiment. That is, each of the first side plates 81, 81 is formed such that the portion where the upper protruding piece 81e is located is wide, and the portion located on the base end side is narrower. For this reason, the 1st to-be-engaged part engaged with each engaging part 12a, 23 cannot be formed only with the 1st lock plate 80. FIG. Therefore, in the present embodiment, the second lock plate 90 is provided, and the first engaged portion is formed by the first lock plate 80 and the second lock plate 90. The second engaged portion 81c that engages with the full-close engagement pin 103 is the window of each first side plate 81, 81 of the first lock plate 80, as in the first embodiment. The rear edge located on the frame 110 side is formed to be cut out in a concave shape.

  Similar to the first lock plate 80, the second lock plate 90 connects two opposing side plates (hereinafter referred to as “second side plate”) 91, 91 and the second side plates 91, 91. Although it has a back plate (hereinafter referred to as “second back plate”) 92, the facing distance between the second side plates 91, 91 is larger than the facing distance between the first side plates 81, 81 of the first lock plate 80. The second side plates 91 and 91 are formed so as to be slightly narrower, and are provided on the inner side of the first side plates 81 and 81, respectively.

  The second lock plate 90 is provided on the shaft member 37 that pivotally supports the lower portions 81a and 81a of the first lock plate 80 so that the first lock plate 80 is independent of the first lock plate 80 and the first lock plate 80. Is pivotally supported so as to be rotatable in the same direction. The tip end portions 91a of the second side plates 91, 91 of the second lock plate 90 are formed in such a shape that the upper end edge 91b becomes substantially horizontal when protruding forward. The second lock plate 90 is urged by an elastic member so that the tip end portion 91 a protrudes forward and can be positioned below the upper protruding piece 81 e of the first lock plate 80. The elastic member is not limited as long as it fulfills such a function, but in the present embodiment, one end is engaged near the lower portion of the front end edge of the second lock plate 90, and between the side plate portions 31, 31 of the traveling member 30. A tension coil spring (hereinafter referred to as “second tension coil spring”) 93 whose other end is engaged with the third spring pin member 39 that has been stretched is urged so that the tip end portion 91a protrudes relatively forward. In the vicinity of the lower end edge of the second side plates 91, 91, front end stoppers 94, 94 projecting downward near the front end edge, and rear end stoppers 95, 95 projecting downward near the rear end edge, respectively. The front end stoppers 94, 94 abut against the second spring pin member 36, thereby restricting the forward rotation range of the second lock plate 90. By Pas 95, 95 comes into contact with the third spring pin member 39 has a configuration in which the range of rotation of the rearward of the second lock plate 90 is regulated.

  In the present embodiment, the first tension coil spring 85 that elastically biases the first lock plate 80 has one end penetrating above the lower portions 81a and 81a of the first side plates 81 and 81. When the first lock plate 80 rotates in a direction to engage with the fully-closed engagement pin 103, the first spring pin member 83 is engaged. Both rotate. For this reason, each second side plate 91, 91 of the second lock plate 90 is allowed to rotate the first spring pin member 83 in order to allow the first spring pin member 83 to rotate. Arc-shaped hole portions 91d and 91d are formed along the moving direction. Of course, when the means for elastically urging the first lock plate 80 does not need to provide the first spring pin member 83 by using another spring member or the like, such a circular arc shape is used. The hole 91d may not be provided.

  Manual operation means is coupled to the second lock plate 90. In this embodiment, as the manual operation means, the substantially U-shaped plate member 61 used in the first embodiment is not used, and the traction string member 62 is configured as the second lock plate 90 on the second back surface. It is connected to the plate 92 and used. As with the first embodiment, the traction string member 62 is provided on the upper portion of the window frame 110 with the other end extending upward along the support frame 20 and one end of the support frame 20 being fixed. It is hung downwardly hung around the pulley member 120. When the operation portion 62a provided at the other end is pulled downward, it is pulled via the second lock plate 90. At this time, since the second back plate 92 is first pulled upward, the second lock plate 90 that has been rotated forward about the base end portion is rotated in the backward direction. For this reason, even if the first engaged portion is engaged with the engagement pin 12a of the actuator 10, that is, the upper protruding piece 81e of the first lock plate 80 and the distal end portion 91a of the second lock plate 90. Even when the engagement pin 12a is positioned between the front end portion 91a and the front end portion 91a of the second lock plate 90, the front end portion 91a of the second lock plate 90 is retracted rearward. Therefore, if the operation portion 62a is pulled further down as it is, the traveling member 30 is moved to the support frame 20 without the tip portion 91a forming the lower edge of the first engaged portion being caught by the engagement pin 12a. Can be raised along. In the state where the second engaged portion 81 c of the first lock plate 80 is engaged with the full-close engagement pin 103, the first lock plate 80 can be simply pulled by pulling the tow string member 62. Is rotated in the direction of the support frame 20, and one end is connected to the second back plate 92 so that the engagement state between the second engaged portion 81 c and the full-close engagement pin 103 is released. It is preferable to dispose the pulled traction member 62 through the rear side of the pin member 88 spanned near the upper portion between the first side plates 81, 81 of the first lock plate 80.

  Here, on the first back plate 82 of the first lock plate 80, a second engaged portion 81c provided in the vicinity of the front end of the first side plate 81, 81 is provided with a full-close engaging member for forced locking. A compulsory locking string member 86 for engaging with the mating pin 103 is connected. The forcibly locking string member 86 is a lock provided on the lock plate 50 in the first embodiment in that it is used for engaging the second engaged portion 81c with the fully closed engaging pin 103. Although it performs the same function as the release strap member 56, it does not need to be used when switching from the automatic operation mode to the manual operation mode, unlike the lock release strap member 56 of the first embodiment. That is, in the above embodiment, when the first engaged portion 51b is engaged with the engagement pin 12a of the actuator 10, in order to release this engagement state, the unlocking lace member 56 is brought forward. Therefore, it is necessary to remove the first engaged portion 51b from the engagement pin 12a of the actuator 10. However, in the present embodiment, as described above, the tip end portion 91a of the second lock plate 90 is retracted rearward simply by pulling and pulling the tow string member 62, and therefore the lower edge of the first engaged portion. The portion corresponding to is no longer present at the start of manual operation, and even if the forcible lock string member 86 is not operated, the manual operation can be performed without being caught by the engagement pin 12a. However, when the traveling member 30 is moved downward by releasing the state of engagement with the fully open engagement pin 23 of the support frame 20, the upper protruding pieces 81e, 81e of the first lock plate 80 are engaged. In order to interfere with the joint pin 23, it is necessary to operate the forcible lock string member 86 and to turn the first lock plate 80 backward once. This point is the same as in the first embodiment. It is the same as the form.

  According to the present embodiment, in the closed state of the wife window 100, as shown in FIG. 8 (a), the forcible lock string member 86 is pulled forward, and the first lock plate 80 is rotated toward the window frame 110 side. Then, the second engaged portion 81c is engaged with the full-close engagement pin 103 of the end window 100 to forcibly lock.

  On the other hand, when the operating portion of the tow string member 62 is pulled downward, the pin member 88 is moved from the rear side by the tension of the tow string member 62 as shown in FIG. The first lock plate 80 is rotated in the direction of the support frame 20, the engagement between the second engaged portion 81 c and the full-close engagement pin 103 is released, and the first lock plate 80 is Is caused. When the first lock plate 80 is raised as described above and the position of the first lock plate 80 is positioned below the engagement pin 12a of the actuator 10, the tow string member 62 is pulled. By doing so, as shown in FIG. 11 (b), when the distal end portion 91a of the second lock plate 90 is retracted and further pulled, as shown in FIG. 11 (c), the first lock plate The inclined end edges 81d and 81d of the first side plates 81 and 81 of the 80 abut against the engaging pin 12a, and the relative positions of the inclined end edge 81d and the engaging pin 12a are shifted, thereby FIG. 11 (d). As shown in FIG. 11, when the first lock plate 80 is slightly rotated backward to get over the engagement pin 12 a, the upper protrusion of the first lock plate 80 is projected as shown in FIG. 81e protrudes forward by the elastic force of the first tension coil spring 85. Further, when the tension of the pulling string member 62 is loosened, as shown in FIG. 11 (f), the second lock plate 90 is rotated forward by the elastic force of the second tension coil spring 93, and the leading end 91a. Protrudes so as to be positioned below the engaging pin 12a. Thereby, the engaging pin 12a is positioned and engaged with the first engaged portion formed by the upper protruding piece 81e and the tip 91a. As a result, against the force in the closing direction of the window 100, the upper protruding piece 81e of the first lock plate 80 that forms the first engaged portion comes into contact with the upper portion of the engaging pin 12a. It is possible to cope with the force in the direction of opening the end window 100 by the tip end portion 91a of the second lock plate 90 forming the first engaged portion being in contact with the lower portion of the engaging pin 12a. Therefore, the same function as the upper protruding piece 51e and the lower protruding piece 51f forming the first engaged portion 51b provided on the lock plate 50 of the first embodiment is achieved.

  In this state, the sun shines and the greenhouse temperature rises, so that the driving material in the cylinder 11 expands and pushes the piston 12 out of the cylinder 11 as shown in FIGS. 7 (a) and 7 (b). The traveling member 30 is guided by the support frame 20 and moved upward, and the wife window 100 is opened around the base end portion 101 via the arm 40. Further, when the temperature decreases and the driving material contracts, the piston 12 is accommodated in the cylinder 11 and the end window 100 is closed, contrary to the above. As described above, the opening angle of the window 100 can be automatically adjusted in accordance with the temperature change without using a power source, as in the above embodiment.

  On the other hand, when the automatic operation mode is canceled and the traveling member 30 is manually operated in the direction in which the traveling member 30 is lifted along the support frame 20 in the direction in which the end window 100 is opened, The operation part 62a is pulled downward. As a result, the tow string member 62 rotates the second lock plate 90 rearward and retracts the tip 91a rearward as in the case of FIG. It can be raised without interfering with 12a. With respect to the fully open engagement pin 23 provided on the support frame 20, the inclined end edge 81d of the first lock plate 80 abuts against the fully open engagement pin 23, as shown in FIGS. 11 (c) to 11 (d). Similarly to the case, when the first lock plate 80 rotates slightly rearward and gets over the fully-opening engagement pin 23, the upper protruding piece 81e protrudes forward, and the traction string member 62 is loosened, thereby The front end portion 91a of the second lock plate 90 protrudes forward and engages (see FIGS. 11E to 11F).

  Therefore, according to the present embodiment, the operation of canceling the automatic operation mode and manually operating in the opening direction can be performed by operating only the tow string member 62, which is more work than in the first embodiment. Is facilitated.

  It should be noted that the first lock plate 80 and the second lock plate 90 are manually operated in a direction to close the end window 100 from a state where the first lock plate 80 and the second lock plate 90 are engaged with the engagement pin 23 for full opening or the engagement pin 12a of the actuator 10. In this case, since the upper protruding piece 81e of the first lock plate 80 is located at the upper part of the fully open engagement pin 23 or the engagement pin 12a of the actuator 10, the force is forced as in the first embodiment. The lock string member 86 is pulled forward, and the first lock plate 80 is once rotated backward.

  In the above embodiment, the wife window is described as an example of the operation target member. However, the other end side pivots around the base end portion to open and close, and other ventilation members and light shielding members provided in the greenhouse. Further, a heat retaining member or the like can be used as the operation target member.
