Description

  The present invention relates to an awning device that is attached to a window of a building or the like and opens and closes for sunshade.

  Conventionally, an awning device for sunshade is connected to a winding portion attached to a window frame, a pair of support posts attached to both ends in the width direction of the window frame, and the support members to be rotatable with respect to the support posts. Patent Document 1 discloses an awning device including an arm that is attached to the arm, a protruding bar that is attached to the tip of the arm and connects the arms, and a canvas that is disposed between the winding unit and the protruding bar. It is disclosed. The awning device disclosed in Patent Document 1 is configured such that the canvas is opened when the overhanging bar moves in accordance with the movement of the arm and pulls the canvas.

Japanese Patent Laying-Open No. 2006-37512 (first page, FIG. 1)

  In the awning device disclosed in the above-mentioned Patent Document 1, it is difficult to freely adjust the position of the canvas because one of the structures for opening the canvas is only winding and the other is only pulling. In addition, there is no rewinding mechanism for rewinding the canvas in the winding part, and when opening the canvas, it is necessary to adjust the angle of the arm with respect to the window frame, so that it can be installed in places such as high places. It is difficult to install smoothly and safely. Furthermore, since there is only one winding part, the force applied to the canvas needs to be fixed by rotating the overhanging bar to a predetermined opening with the canvas fully stretched. . Further, since the position of the use surface of the canvas fabric is fixed when the canvas is opened, the canvas is liable to cause local wear.

  Therefore, the present invention is to provide an awning device that can freely adjust the position of the use surface of the canvas while maintaining a stretched state, and to provide an awning device that can perform a smooth opening and closing operation. .

  Means taken in order to solve the above-described problems include a first winding portion attached to the upper portion of the window portion, a drive mechanism for rotating the first winding portion so as to be able to wind and unwind, and one end of the frame. Between the first winding unit and the second winding unit, the second winding unit that is attached to the other end of the arm and that has a biasing force acting in a certain rotational direction. A biasing mechanism provided between the arm and the window, and an urging force acting in a direction in which the arm expands an angle with respect to the window on the first winding unit side, and the arm as a urging force And a stopper mechanism that locks at a predetermined angle. The canvas opening operation rewinds the first winding portion by the drive mechanism, and the second winding portion attached to the other end of the arm The arm rotates with the arm by the biasing force, and the stopper mechanism The canvas is opened by being locked in place, and the fabric of the canvas is adjusted by rewinding the first winding portion and winding the second winding portion, and the closing operation is performed by the urging force of the arm and the second winding portion. The canvas is closed by winding the first winding portion with a driving mechanism with a force larger than the winding force of the first winding portion.

  Further, the rotation operation of the first winding unit may be performed by winding and rewinding by a rotating means using a motor or a gear.

  The canvas may have a plurality of patterns or a plurality of different fabrics.

  Furthermore, the stopper mechanism is disposed between the window portion and one end of the arm, provided with a plurality of locking holes, and locks the direction of the urging force of the arm by inserting a pin into the locking hole. And good.

Moreover, the means taken in order to solve the above-mentioned problems are a first winding part attached to the upper part of the window part, a drive mechanism for rotating the first winding part so as to be able to wind and rewind, and a window. An arm whose one end is pivotally attached to the part, a second winding part which is attached to the other end of the arm and exerts a biasing force in a certain rotational direction, and a first winding part and a second winding part A biasing mechanism provided between the arm and the window, a biasing force acting in a direction in which the arm expands an angle with respect to the window on the first winding unit side, Has a bent portion that abuts the window portion when fully opened and locks the arm in the urging direction, and the canvas opening operation is performed by rewinding the first winding portion by a drive mechanism and being attached to the other end of the arm. The second winding part is rotated with respect to the window part together with the arm by the urging force of the arm, and is bent by the bent part. The canvas is opened by being locked at an arbitrary position, and the fabric of the canvas is adjusted by unwinding the first winding portion and winding the second winding portion. The canvas is closed by winding the first winding unit with a driving mechanism with a force greater than the winding force of the winding unit.

  According to the present invention, the awning device has a rewinding and winding function in the first winding unit, and a winding function in the second winding unit. Furthermore, the urging force is acting on the arm in a direction that widens the angle with respect to the window. Therefore, the awning device smoothly opens the canvas because the direction of the force to send the canvas is constant by the rewinding of the first winding unit, the winding of the second winding unit, and the urging force of the arm. Further, the awning device smoothly winds the canvas in the closing operation because the rewinding of the first winding unit is larger than the winding force of the second winding unit and the urging force of the arm, which are the two forces described above. be able to. In addition, the position of the canvas when the arm reaches an arbitrary position by the stopper structure during the opening operation can be adjusted based on the relationship between the rewinding of the first winding unit and the winding of the second winding unit. It is. As a result, the canvas can suppress local wear by adjusting the surface to be used, and the durability of the canvas can be increased. In addition, since the durability of the canvas is increased, the user can reduce the work of replacing the canvas. However, the urging force of the arm must be larger than the winding force of the second winding unit.

  In this awning device, even when the drive mechanism of the first winding unit is an electric mechanism using a motor or a mechanical mechanism such as a gear, the winding force during the closing operation is larger than the winding force of the second winding unit and the urging force of the arm. If it is established, the user can use the awning device by selecting a driving method suitable for the environment. The rotation operation by the motor and the gear can adjust the force in both the winding and rewinding directions.

  This campus may be composed of a combination of a plurality of patterns and different shades of color on one fabric. Further, the canvas may be configured by connecting a plurality of different fabrics. Thereby, it becomes possible for the user to select a combination suitable for the living environment depending on the nature of the fabric or pattern of the canvas.

  Furthermore, the stopper mechanism of the awning device allows the user to lock the arm at an arbitrary angle by inserting locking pins into a plurality of locking holes provided in the circumferential direction of the arm. The stopper structure described above is attached to the window portion, and the operation of setting the arm at an arbitrary position can be performed in the vicinity of the window portion. Therefore, the awning device can be used safely even in places such as high places.

  Further, the arm having the stopper mechanism is bent at an arbitrary angle near the center of rotation with the window portion, and the bent portion abuts on the window frame to serve as a stopper. The user determines the angle of the canvas for performing necessary light shielding by selecting a predetermined arm, but the operation of selecting the stopper position can be simplified.

  Embodiments of the present invention will be described below.

Example 1
Hereinafter, the configuration of the awning apparatus 1 according to the first embodiment of the present invention will be described. FIG. 1 is a perspective view of an awning device 1 according to the first embodiment.

  As shown in FIG. 1, the awning device 1 has an upper portion of a window portion 20 for taking in sunlight such as a building, and both ends of the first winding portion 30 in the state parallel to the window portion 20 are around the window periphery 21 of the window portion 20. It arrange | positions via the support body 40 fixed to the right-and-left end. Further, a pair of left and right arms 50 are attached to the window periphery 21 below the left and right window portions 20. One of the arms 50 is attached in a rotatable state, and the other is attached with a second winding part 60 that is substantially the same length as the first winding part 30 so as to face the first winding part 30. ing. A stopper mechanism 70 that locks the vertical rotation of the arm 50 at a predetermined angle is attached to the joint portion between the arm 50 and the window portion 20 with respect to the window portion 20.

  In the first winding unit 30 and the second winding unit 60, a state in which a fabric canvas 80 in which a plurality of fabrics are connected in series is always stretched by a winding mechanism provided in the second winding unit 60 described later. It has a configuration that can be maintained. The first winding unit 30 can be rewound and wound using a drive mechanism described later. The second winding unit 60 is always urged in the winding direction of the canvas 80 (counterclockwise direction shown in FIG. 1) by a spring mechanism provided therein, and the winding of the canvas 80 is performed by the urging force of the spring. It is possible. The arm 50 is made of a pipe-shaped metal, and a biasing force is applied in a direction of pulling the canvas 80 downward so that the second winding unit 60 is separated from the first winding unit 30. As shown in FIG. 1, when the canvas 80 is opened in the opening direction, the first winding unit 30 is rewound (counterclockwise turning operation shown in FIG. 1) and the second winding unit 60 is wound (see FIG. 1). The counterclockwise turning operation shown in FIG. 1 is performed by the urging force of the arm 50 by the spring. In this case, the urging force for rotating the arm 50 downward is set larger than the force for winding the canvas 80 of the second winding unit 60. For this reason, while maintaining the state where the canvas 80 is sufficiently stretched, the arm 50 is rotated downward about one point, and is rotated to a position where the side surface of the arm 50 is locked to the stopper mechanism 70. Can do. On the other hand, when the canvas 80 is stored as shown in FIG. 7A, the first winding portion is more than the force of winding the canvas 80 of the second winding portion 60 and the urging force of rotating the arm 50 downward. By setting the winding force of 30, that is, the output of the driving mechanism provided inside, to be larger, the canvas 80 can be closed.

  As shown in FIG. 1, in the case of using a plurality of fabrics for the canvas 80, for example, in the case of a light shielding fabric and a mesh fabric, the light shielding fabric does not allow direct sunlight to enter the room, thereby preventing fading of furniture, floors, etc. The mesh fabric can be seen outdoors from the room, and the pressure on the room can be reduced. Further, by combining the two fabrics in this way, for example, when a light-shielding fabric and a mesh fabric are used at the same time, it is possible to reduce the direct indoor solar radiation while ensuring the indoor illuminance. At this time, since the fabrics are combined in a column, the properties of each fabric can be used effectively. In addition, as a modification of the canvas 80, it is possible to use a single cloth or a resin sheet. In this case, in order to suppress solar radiation, only a predetermined area above is colored darker than the lower part. It goes without saying that the same effect as described above can be obtained by adding a pattern, a predetermined pattern, or a pattern. In addition, the canvas 80 may have at least two patterns of colors (light color and dark color, transparent color and darker color than transparent color, etc.) in order to suppress the sunshine caused by solar radiation.

  Next, the 1st winding part 30 of the awning apparatus 1 concerning this invention is demonstrated with reference to FIG.

  FIG. 2 is an explanatory diagram illustrating a cross-sectional state of the first winding unit 30 in the awning device 1 illustrated in FIG. 1. As shown in FIG. 2, the first winding unit 30 is supported by both ends, one is fixed to the support 40a, and the other is rotatably supported by the support 40b. The first winding unit 30 includes a motor 31 having one end fixed as a driving source of the driving mechanism, a rotating unit 32 that rotates as an output of the motor 31, and a rotating unit 32 for winding and rewinding the canvas 80. A cylindrical first roll 33 attached to the first roll 33, a shaft 34 that rotates integrally with the first roll 33, and a detection member 34 that is located close to the shaft 34 and detects the end of the canvas 80. Yes. The motor 31 is fixed to one support body 40 a of the support body 40 that supports the first winding unit 30, and a first roll 33 is attached to a rotating portion of the motor 31. Further, the shaft 34 is rotatably supported by the other support body 40b. The first winding unit 30 rotates and rotates the rotating unit 32 simultaneously with the rotation of the motor 31 (forward rotation or reverse rotation), and the first roll 33 rotates accordingly. It has a configuration that can be performed. Further, since the shaft 34 is rotated by the first roll 33 rotating in one direction, the detection member 35 provided on the fixed side of the support 40 b is rewound or wound up from the rotation state of the shaft 34. Can be detected in contact or non-contact. The detection member 35 is a known member and will not be described in detail.

  Next, the 2nd winding part 60 in the awning apparatus 1 is demonstrated with reference to FIG. 3 and FIG. FIG. 3 is a perspective view of the second winding unit 60 of the awning device 1, and FIG. 4 is an explanatory view showing a cross-sectional state of the second winding unit 60 shown in FIG. 3.

  As shown in FIG. 3, the second winding unit 60 has a hollow shape in which a canvas 80 is wound around an elongated support frame 64 that has a U-shaped cross section and is fixed to the distal ends of a pair of arms 50, with both ends protruding vertically. The second roll 61 is rotatably supported. A shaft portion 62 is provided inside the second roll 61 serving as a rotation shaft of the second roll 61, and both ends are locked to the second roll 61 and the shaft portion 62 between the second roll 61 and the shaft portion 62. A spring 63 is provided for applying a biasing force to wind up the canvas 80. As shown in FIG. 4, the spring 63 disposed in the second roll 62 has one end attached to the second roll 61 and the other attached to the middle wall of the shaft portion 62 using attachment means 65 such as a rivet, The shaft portion 62 is fixed at both ends of the support frame 64 by screws 66. For this reason, if the 2nd roll 61 rotates, the urging | biasing force will increase to the spring 63 by the part which rotated. Further, the urging force in the winding direction of the second winding unit 60 is large when the canvas 80 is pulled, is maximum when the canvas 80 is open, and gradually decreases as the canvas 80 is wound. It becomes the minimum when the canvas 80 is closed.

  Next, a stopper mechanism 70 that rotatably supports the arm 50 and locks the rotation of the arm 50 at a predetermined angle will be described with reference to FIGS. 5 and 6. FIG. 5 shows the state of the stopper mechanism 70 in the awning device 1 shown in FIG. 1 at a locking angle of 90 degrees, and FIG. 6 is an enlarged fragmentary view showing the state of the stopper mechanism 70 in a locking angle of 135 degrees. It is. The angle of the locking angle is an angle formed by the window portion 20 and the arm 50 among the inner angles of the triangle formed by the arm 50 and the window portion 20 to which the arm 50 is attached (or a window frame) 20 and the canvas 80. It is defined as The angles shown below shall mean this definition.

  As shown in FIG. 5, the stopper mechanism 70 is provided with two metal plate members 71 so as to sandwich one arm 50 from both the left and right sides, and the plate member 71 is moved in the circumferential direction in which the arm 50 rotates. A plurality of locking holes 72 are provided in the circumferential direction (for example, the number is not limited, but two here). By inserting a locking pin 73 having a head at one end from the outside into the locking hole 72, the side surface of the arm 50 comes into contact with the side surface of the locking pin 73, thereby rotating the arm 50 to a predetermined angle. It is possible to regulate so that 5 and 6 show cases where the rotation angle of the arm 50 is 90 degrees and 135 degrees due to the locking hole 72. FIG. In FIG. 5, a locking hole 72 is provided in the plate member 71 at a position where the arm 50 is horizontal 90 degrees, and the arm 50 is inserted by inserting a locking pin 73 into the position of the locking hole 72. The rotation angle is locked. 6, similarly to FIG. 5, the locking pin 73 is inserted into the locking hole 72 at 135 degrees so that the rotation angle of the arm 50 is at a position of 135 degrees and the rotation of the arm 50 can be locked. Thus, the state of FIG. 6 can be obtained. Since the plurality of locking holes 72 are provided in this way, the arm at various angles can be locked, and the user can freely set the locking pin 73 at an angle according to his / her preference or application. It is possible to select by changing the position of.

  Next, the urging mechanism 90 of the arm 50 will be described with reference to FIG. FIG. 7 is an explanatory diagram for explaining the biasing mechanism 90 of the arm 50. (A) shows the case where the arm angle of the arm 50 is 10 degrees, (b) shows the case where the arm 50 angle is vertical (90 degrees), and (c) shows the case where the arm 50 angle is 135 degrees.

  As shown in FIG. 7, a biasing mechanism 90 provided mainly inside the arm 50 is provided with a coiled tension spring 91, one on the second winding part 60 side of the arm 50 and the other a wire. It is locked and attached to the rotating shaft 93 through 92. Further, the wire 92 is attached to the installation portion 74 that installs the stopper mechanism 70 on the window portion 20 via a rotating shaft 93 with the stopper mechanism 70 in a state where the wire 92 is locked by a fixing means 94 such as a screw, and the tip has a square shape. The bent portion is in contact with the installation portion 74 having a flat shape. In this case, the wire 92 is locked via the rotating shaft 93 and pulled by the tension spring 91, whereby the tension of the wire 92 changes at the rotating shaft 93 depending on the rotation angle of the arm 50, and the tension of the tension spring 91 is also increased. It changes with this. As shown in FIGS. 7A to 7C, the installation area of the rotary shaft 93 and the wire 92 gradually decreases as the rotation angle of the arm 50 increases. For this reason, since the tension of the urging mechanism 90 inside the arm 50 is weakened when the rotation angle of the arm 50 is increased, the urging force of the arm 50 is also reduced. As a result, the initial operation of the awning device 1 from the closed state to the open state can be performed smoothly because the urging force of the urging mechanism 90 starts from the maximum.

  Next, operation | movement of the awning apparatus 1 is demonstrated with reference to FIGS. FIG. 8 shows a perspective view when the canvas 80 of the awning device 1 is in a closed state. FIG. 9 shows a perspective view when the canvas 80 of the awning device 1 is fully opened. FIG. 10 is a perspective view in the case where the fabrics in which the half in the vertical direction of the canvas 80 is different when the canvas 80 is fully open are used. Further, FIG. 11 shows a perspective view when the fabric of the canvas 80 is completely replaced when the canvas 80 is fully opened. The angle of the arm 50 in FIGS. 8 to 11 can be opened up to 135 degrees.

  As shown in FIG. 8, when the canvas 80 of the awning device is in the closed state, the canvas 80 is wound most on the first winding unit 30 side. On the other hand, the second winding unit 60 can be configured such that the joint surface with the lower end of the canvas 80 is exposed from the outside. In this state, since the second winding unit 60 winds the canvas 80 by the first winding unit 30, the urging force in the winding direction of the second winding unit 60 (counterclockwise in FIG. 8). ) Is maximized, and the urging force acting on the arm 50 by the urging mechanism 90 is also maximized. At this time, the motor 31 provided inside the first winding unit 30 causes the force in the winding direction of the first winding unit 30 to be applied to the urging force of the second winding unit 60 in the winding direction and the arm 50. Therefore, even when the above two forces are maximized, the operation to the open state is not restricted. When the canvas 80 is moved from the closed state to the open state, the arm 50 is rotated by the motor 31 of the first winding unit 30 (the counterclockwise rotation shown in FIG. 8). Since the movement is caused by the urging force, the opening operation is performed with the canvas 80 sufficiently stretched without slack as shown in FIG. In this opening operation, winding by the second winding unit 60 is not performed until the side surface of the arm 50 is locked by the position of the locking pin 73 inserted into the stopper mechanism 70. This is because the urging force of the arm 50 is larger than the urging force of the second winding unit 60 in the winding direction, so that the canvas 50 is not wound around the second winding unit 60 and the arm 50 is engaged. It is possible to continue the state of being stretched to the position where it is stopped. After the arm 50 is locked by the locking pin 73, when the first winding unit 30 performs the rewinding operation again, the canvas 80 is wound by the urging force of the second winding unit 60. When the second winding unit 60 winds up the canvas 80, if the canvas 80 is connected in a column with different fabrics, different fabrics can be used for the canvas 80 as shown in FIG. The person can use it according to his / her preference or purpose. Furthermore, the boundary of the fabric of the canvas 80 can be set at any position of the user by changing the winding amount by the motor 31. Further, as shown in FIG. 11, when the second winding unit 60 continues the winding operation, the canvas 80 can be made of only a cloth different from the first cloth. 9 to 11, unless the motor 31 performs the winding operation, the urging force always acts on the arm 50 in the counterclockwise direction, that is, in the direction in which the rotation angle of the arm 50 increases. Since it does not move from the locking position of the stopper mechanism 70 by the locking pin 73, a smooth opening operation is performed. The operation from the open state to the closed state is based on the force relationship between the winding force of the first winding unit 30 and the biasing force of the second winding unit 60 in the winding direction and the biasing force of the arm 50. 80 is wound from the second winding unit 60 to the first winding unit 30, and then the arm 50 is moved.

(Example 2)
Hereinafter, the configuration of the awning device 1 according to the second embodiment of the present invention will be described with reference to FIGS. 12 shows a perspective view of the closed state of the awning device 1 including the stopper mechanism 70 in the arm 50, and FIG. 13 shows a perspective view of the opened state of the awning device 1 shown in FIG. 14 is a perspective view in which the cover unit 100 is attached above the awning device 1 shown in FIG. 12, and FIG. 15 is a perspective view in which the cover unit 100 is attached to the awning device 1 shown in FIG.

  As shown in FIGS. 12 and 13, the configuration of the second embodiment is the same as the configuration of the first embodiment, and the description of the same configuration is omitted. The difference from the first embodiment is mainly that the arm 50 is provided with a bent portion 51 in which a joint portion with the window portion 20 is bent at an arbitrary angle. With such a configuration, when the canvas 80 is changed from the closed state to the open state, the bent portion 51 comes into contact with the window portion 20, so that the arm 50 is locked at a set angle. Therefore, since the awning device 1 locks the arm 50 at a preset angle, the stopper mechanism 70 can be simplified. Further, the second winding part 60 joins both ends of the shaft part 62 to the arm 50 without using the support frame 64. The arm 50 is rotatably attached to the window portion 20 by a rotating shaft 93 attached to the plate member 71.

  14 and 15, the cover 100 is attached to the window 20 in the awning device 1. The cover unit 100 includes a first cover unit 101 in which the first winding unit 30 and the support body 40 are stored, and a second cover unit 102 in which the second winding unit 60 is stored. . The first cover unit 101 includes a base cover 103 whose upper surface covers the entire first winding unit, and a side wall cover 104 that covers the side surface of the base cover 103. The base cover 103 can be attached to the window portion 20 by fitting the side wall cover 104 to both bent ends. Further, the base cover 103 is provided with an opening 105 on the side facing the window 20, and the second cover 102 is accommodated in the opening 105. Further, the side wall cover 104 is shaped to cover the support body 40 attached to the window portion 20. Further, the second cover portion 102 is fixed to the second winding portion 60 and moves simultaneously with the rotation of the arm 50 in the open state, and is interposed in the opening portion 105 of the base cover 103 in the closed state. . Accordingly, the first winding unit 30, the second winding unit 60, and the canvas 80 are stored in the cover unit 100. As a result, the appearance of the awning device 1 can be enhanced and the design can be enhanced, and the failure of the motor 31 caused by water and dust due to wind and rain can be reduced.

  As mentioned above, although the structure of Example 1 and Example 2 was demonstrated, this invention is not limited to this, You may change into the aspect shown below.

-The motor 31 which is a drive mechanism of the 1st winding part 30 is good also as a structure which winds and unwinds by a gear mechanism. At this time, the winding force of the gear mechanism is set to be larger than the winding force of the second winding unit 60 and the urging force of the arm 50.

-The 2nd winding part 60 is good also as an electrically-driven winding structure. Even in such a configuration, the awning device 1 controls the winding operation of the second winding unit 60 simultaneously with the opening / closing operation of the first winding unit 30, so that the fabric 80 can be held while being stretched. Adjustments can be made.

A seal structure may be formed between the first cover part 101 and the second cover part 102. Thereby, the awning device 1 can increase the reduction effect of the failure of the motor 31 caused by water and dust caused by wind and rain.

-The cover part 100 described in Example 2 may be attached to the awning apparatus 1 of Example 1. FIG. In this case, since the structure to be attached is the same as that of the second embodiment, the effect obtained after the attachment can be similarly enhanced in the appearance and the failure of the motor 31 can be reduced.

A cover for preventing pinching may be attached to the stopper mechanism 70 or the plate member 71 having the rotation shaft 93 of the arm 50 of the first and second embodiments. Since the rotation shaft 93 of the arm 50 is close to the window portion 20 and the user may get a finger or the like between the arm 50 and the stopper mechanism 70 or the plate member 71, it can be prevented by attaching a cover. Become.

In the first and second embodiments, the arm 50 is rotated with respect to the window portion 20 in the vertical direction. As the shape to be folded, the respective arms are attached in the left-right direction of the window portion 20, and the folded arms on both the left and right sides are projected outward from the window portion 20 by a predetermined amount by using the urging force of the springs. The provided canvas 80 may be sufficiently stretched by the first winding unit 30 or the second winding unit 60 shown in the first embodiment.
