There is a type of awning (Patent Document 1).

Japanese Unexamined Patent Publication No. 2014-169563

Since this pergola type awning is always installed outdoors, it is usually required to adopt a strong frame structure and to be firmly fixed to the ground as a countermeasure against strong winds. Moreover, the awning is easily affected by the wind, and sufficient measures against gusts and strong winds are required for outdoor use. For this reason, on days when strong winds are expected to blow, consideration can be given to moving the sunshade sheet to one corner of the roof frame to make it less susceptible to wind, but when a sudden strong wind blows, For example, there is no time to clean up the awning sheet, and there is a risk that the fabric and skeleton will be damaged. In addition, the awning sheet is constructed by connecting multiple small sheet materials with a awning frame that moves along the rails of the girder of the frame, so it is strong even if the awning sheet is placed in one corner of the roof frame. There is also a risk that the skeletons will collide with each other due to the wind and generate noise.

Therefore, an object of the present invention is to provide a awning having a wind vent function for catching the wind when it receives the wind, while sufficiently fulfilling the function as the awning.

The awning according to the invention according to claim 1 for achieving such an object includes a support frame having a roof frame, a pivot shaft erected across the roof frame, and a plurality of awnings supported by the pivot shaft and rotatable around the pivot shaft. Panels and a restoration means to return the panels to the horizontal position when the panels are not exposed to the wind, and the panels are arranged with a rotatable gap around the pivot axis without interfering with each other. It constitutes a awning surface, and the panel is kept in a horizontal position when it does not receive the wind, and when it receives the wind, it rotates and turns to pass the wind.

Here, it is preferable that the panel is fixed to the pivot, the pivot is rotatably supported by the roof frame, and the panel rotates with the pivot.

In addition, the restoring means is a spring, which is provided with springs that wind in reverse to each other at both ends of the pivot, urges the spring force that holds the panel horizontally, and allows the pivot to rotate when it receives wind. When it is settled, it is preferable that the position of the panel is restored horizontally by the force of the spring.

Further, the restoration means is a weight that sets the position of the center of gravity below the center of rotation of the pivot, and it is preferable that the panel is automatically restored to the horizontal state by gravity.

According to the awning according to the present invention, when the wind blows, the panel where the wind hits rotates around the pivot axis to pass the wind, so that the blow-up load or the blow-down load is reduced and the columns are blown off. It becomes difficult to be knocked down. Moreover, since it can be parried without being directly affected by the wind, the burden on the panel and the pivot can be reduced and damage can be avoided. Further, since the panel rotates to catch the wind, the panel does not flutter in the wind and scatter off the pivot, which is highly safe. Further, since the panel rotates around the pivot mounted on the roof frame, the panel does not collide with or come into contact with the user under the awning.

Moreover, when the wind weakens, the panel is restored to its original position by the action of the restoration means, so that the original function as a awning can be fully restored. That is, according to the awning of the present invention, when there is no wind or there is a breeze, the gap between the panels is closed to form a awning surface, so that it can serve as a awning to block strong direct sunlight. The panel fluctuates due to the wind, and the sunlight shines in like sunlight through the trees, allowing you to receive soft sunlight.

Here is an example of how to do it. It is a top view which shows the other embodiment of a panel. FIG. 5 is a plan view showing still another embodiment of the panel.

Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings.

1 to 3 show an example of an embodiment in which the awning of the present invention is applied to a four-post paragola type awning. The paragola type awning according to this embodiment includes a support frame 1 having a roof frame 4 and a movable awning 6 erected on the roof frame 4 to form a awning surface 7.

The movable awning 6 includes a pivot 10 erected across the roof frame 4, a plurality of awning panels 11 supported by the pivot 10 and rotatable around the pivot 10, and when the awning panel 11 does not receive wind. A restoring means 12 for returning the awning panel 11 to the horizontal posture is provided, and the awning panels 11 are arranged with a rotatable gap around the pivot 10 without interfering with each other, and the awning surface is formed by an aggregate of the plurality of awning panels 11. 7 is configured, and the awning panel 11 is kept in a horizontal posture when it does not receive the wind, and when it receives the wind, it rotates and changes its direction to pass the wind.

In the case of the present embodiment, the support frame 1 is a corner where, for example, four columns 2, four beams 3 whose ends are supported by the columns 2, and beams 3 in two directions orthogonal to the columns 1 intersect. It is provided with a corner joint 5 that surrounds the portion, and is assembled by connecting the support column 1, the beam 3, and the corner joint 5, respectively. Here, four beams 3 are assembled in a rectangular parallelepiped shape to form a roof frame 4, and the roof frame 4 is supported by four columns 2 at a desired height. In the present specification, the roof frame means all the structures that can support the pivot 10, and is not necessarily limited to the closed structure by connecting four beams as in the present embodiment. No.

Here, the support column 1 may be one as shown in FIGS. 2 and 3, for example, an extruded aluminum alloy product or a square pipe, but in some cases, a plurality of columns (not shown) can be expanded and contracted. It may be a nesting type telescopic structure (telescopic structure) that can be fixed by a connecting tool at an arbitrary position. For example, by combining square cylinders of different sizes to form a nested telescopic structure (telescopic structure) in which the other prism is slidably connected to one prism, the prism 1 is provided so as to be expandable. May be done. From the viewpoint of expansion and contraction, any of the prisms may be large in the nested prism, but preferably, a nested structure in which the lower prism can be fitted with respect to the upper prism, that is, the inside of the upper prism. The outer dimension of the lower prism is made smaller than the dimension so that rainwater or the like does not enter through the gap between the upper prism and the lower prism and collect.

The corner joint 5 surrounds a corner where the support column 1 and the beam 3 are orthogonal to each other, and the support column 1 and the beam are connected to the support column 1 and the beam 3 by bolting or the like, respectively. 3 is connected to each other. Although not shown, angles are welded to the inside of each of the three surfaces of the corner joint 5 at intervals of substantially the same width as the columns 1 or the beam 3, and the rising sides of the angles (fixed). The position can be regulated by inserting the support column 1 or the beam 3 into the space between the side perpendicular to the surface) and the inner surface of the corner joint 5 facing the side).

The support column 1 may be fixed by constructing a foundation, but the method is not particularly limited to this, and weight fixing or anchor fixing is preferable. For example, the lower end of the support column 1 is provided with a load receiving portion 8 that protrudes laterally from the support column 1 and receives the weight 9. The support column 1 may be fixed by placing the weight 9 on the load receiving portion 8. Here, the load receiving portion 8 not only has a function of mounting the weight 9 but also has a function of widening the installation area of the support column 1 to prevent it from falling over.

The weight 9 is, for example, a split ring made of semi-cast iron, and one ring (weight assembly) is formed by combining the weights 9 so as to surround the support columns 1, and the weights 9 are further stacked on the weights to form a cylindrical shape. .. The weight of the weight 9 is adjusted by increasing or decreasing the number of stages of the weight assembly to be stacked. Of course, the weight 9 is not limited to the above-mentioned cast iron, but may be made of concrete or a plastic container that is made into a weight by injecting water or the like, and the shape is not limited to the half ring shape and is rectangular. It may be a block with a shape or a U shape. Since the support is simply fixed by placing the weight 9, there is no need for large-scale work such as foundation work. Therefore, it enables simple and quick assembly and disassembly, and is ideal for simple installation for a limited time.

The awning panel 11 has a size that does not come into contact with people standing under the awning when rotating about the pivot 10, specifically, although it depends on the height of the support column 2, according to the present embodiment. In the case, for example, it is a small panel having a side of about 30 to 40 cm and having four corners cut off in an arc shape, and a large number of panels are assembled to form one large awning surface 7. Specifically, in the present embodiment, for example, five rows of substantially square awning panels 11 having a size of about 35 cm × 35 cm are arranged and fixed to one pivot 10 at regular intervals in a row, and five rows at equal intervals. They are arranged and rotatably supported between the beams 3 of the roof frame 4. As a result, 25 awning panels 11 are arranged in a 3 m × 3 m roof frame 4 so as not to interfere with each other and interfere with the beam 3 when rotating, and one awning surface 7 is formed. There is.

In the case of the present embodiment, the awning panel 11 is fixed to the awning panel 10 by screwing or the like so that the Axis 10 is arranged diagonally on the substantially square awning panel 11, so that the awning panel 11 is fixed to the Axis 10 in the left-right direction (Axis 10). It takes a form in which triangular wings protruding in the lateral direction of the wing are formed intermittently, but the wing is not particularly limited to this, and the orientation and fixing method of the arrangement are not particularly limited to this. For example, as shown in FIG. 8, one rectangular strip-shaped awning panel 11 which is slightly shorter than the Axis 10 and has a width sufficient to leave a slight gap between the Axis 10 on both sides is fixed to the Axis 10. You may try to do it. Further, as shown in FIG. 9, for example, square or rectangular awning panels 11 having a length slightly shorter than twice the distance between adjacent pivots 10 are arranged in a staggered pattern among the plurality of pivots 10. You may. Of course, the number of awning panels 11 and the arrangement interval are appropriately determined, but a gap is set so as not to interfere with the surrounding awning panels 11 when the awning panels 11 rotate around the pivot 10. .. Here, it is preferable that the gap does not become too large and the sunlight leaking from between the awning panels 11 does not become too large.

The awning panel 11 is not limited to a specific material, but for example, it is preferable to use a polycarbonate panel having excellent weather resistance and strength. In the present embodiment, all the awning panels 11 have the same size and the same shape, but in some cases, the sizes of some or all of the awning panels 11 may be different, or different designs may be used. When coloring or designing the awning panel 11, it is possible to enjoy the taste of changing the pattern or color scheme by rotating the awning panel 11.

Further, it is not necessary that all the awning panels 11 are supported so as to be rotatable at all times, and some awning panels 11 may be arbitrarily fixed or may be fixed at all times. For example, the pivots 10 may be fixed every other row to regulate the rotation of the awning panel 11, or a part of the pivots may be fixed as needed. Also in this case, by rotating a part of the remaining awning panel 11, it is possible to achieve the effect of venting the wind and creating a space such as sunlight through the trees.

Further, in addition to the rotating awning panel 11, a non-rotating awning panel 13 may be provided. For example, a fixed awning panel 13 may be provided to fill a space near the roof frame 4 (that is, a space between the rotating awning panel 11 and the roof frame 4). In the case of the embodiment of FIG. 1, a saw blade-shaped fixed awning panel 13 as shown by a virtual line is arranged so as to project inward from the roof frame 4 and fixed around an aggregate of rotating awning panels 11. The rectangular roof frame may be surrounded by the awning panel 13 so as to be filled with the awning panel 11 and the fixed awning panel 13. In this case, it is possible to shield the area almost the same as the paragola type awning on which the canvas is developed, and to shade it like sunlight through the trees.

In this embodiment, for example, a square pipe made of an extruded aluminum material is used as the pivot 10. By using the square pipe, a plurality of awning panels 11 are arranged and fixed on the same plane, so that the orientation and horizontal posture of the awning panels 11 can be easily aligned. In the case of the square pipe / pivot 10, for example, as shown in FIGS. 4 to 6, by providing rotating shafts 14 at both ends, it is possible to rotatably attach the square pipe / pivot 10 to the bracket 18 on the beam 3 of the roof frame 4. It is said. Of course, the pivot 10 is not limited to a specific support structure as long as it is rotatably attached to the roof frame 4.

In the case of the present embodiment, the rotary shaft portion 14 is attached to the open end of the pivot shaft 10 via a U-shaped fixing plate 15 which is non-rotatably fixed to the pivot shaft 10 of the square pipe as shown in FIGS. 4 and 5. Has been done. The fixing plate 15 is formed by inserting the leg portions (parallel two sides) at both ends bent inward into the square pipe (axis 10) and then fixing the two sides of the square pipe with screws 29. It is attached to the open end of. The fixing plate 15 and the rotating shaft portion 14 are non-rotatably integrated by fixing with two screws 17 in a state where the end surface of the rotating shaft portion 14 is in contact with the bottom portion between both legs of the fixing plate 15. Has been done. Therefore, the pivot 10 is rotatably supported by the bracket 18 fixed to the beam 3 via the rotation shaft portions 14 at both ends. A slit 16 for hooking one end of the spiral spring 24 is provided at the tip of the rotating shaft portion 14.

The bracket 18 is, for example, an L-shaped plate material (angle material), and a circular hole 21 through which the rotating shaft portion 14 penetrates is formed in a vertically rising bearing portion 19, and a screw (for fixing to the beam 3) is provided in the bottom portion 20. An elongated hole 30 is provided for passing through (not shown). The rotating shaft portion 14 penetrates the circular hole 21 of the bracket 18 with a bearing oilless (oil-free, self-lubricating) bushing, for example, a cylindrical resin sliding bearing 22 fitted therein, and then a C-shaped retaining ring 23 is used. The rotating shaft portion 14 is prevented from coming off and is rotatably supported by the bracket 18. Here, since it is sufficient for the beam 3 to function as a simple structure, in the case of the present embodiment, it is composed of, for example, a simple square cylinder. Therefore, in order to fix the bracket 18, for example, a back metal 31 is applied and screwed.

In the case of the present embodiment, the restoration means 12 is incorporated in the rotating shaft portion 14. In the case of this embodiment, the restoration means 12 uses a spring, for example, a spiral spring 24. The spiral spring 24 has two parallel screws 25, one end of which is passed through a slit 16 at the tip of the rotating shaft portion 14 and hooked, while the other end of the spiral spring 24 is screwed to the bracket 18. It is hooked on the screw 25 so as to pass through. The spiral springs 24 are used in combination so that the spiral springs in the same winding direction have opposite winding directions when they are attached to the rotating shaft portions 14 at both ends of the pivot 10. That is, a left-handed spiral spring is mounted on one end side of the pivot 10 and a right-handed spiral spring is mounted on the other end side so as to urge each other in opposite directions. Therefore, the Axis 10 is constantly urged by spring forces in opposite directions so that the awning panel 11 screwed to the bottom surface is balanced at a position where the awning panel 11 is screwed to the bottom surface regardless of which direction the Axis 10 rotates. Be adjusted. Of course, a left-handed spiral spring and a right-handed spiral spring may be used in combination. A cover 26 is attached to the bracket 18, and the rotating shaft portion 14, the spiral spring 24, the C-shaped retaining ring 23, the bearing oilless bush 22, and the like are covered so as to be protected from dust and the like.

Of course, the pivot 10 is not limited to the square pipe, and may be a round pipe or a round bar. In this case, the trouble of attaching the rotating shaft portion can be saved and the structure is simplified, but it is necessary to consider misalignment when attaching the awning panel 11. On the other hand, when a round pipe or a round bar is used as the pivot 10, the awning panel 11 is fixed to the round pipe and then attached to the pivot 10 with a collar spacer interposed in the axial direction (although not shown). (Double pipe structure), each awning panel 11 can be freely rotatably supported. In this case, since the wind parry is the unit of the awning panel 11, finer adjustment is possible and the movement of the awning panel 11 is also rich in variation, which makes the situation closer to the state of natural sunlight through the trees. It will be possible to reproduce.

Further, as the restoring means 12 of the movable awning 6, for example, a weight 27 may be used. For example, as shown in FIG. 7, the weight 27 may be attached to the bottom surface side of the pivot 10 with the awn panel 11 interposed therebetween by using the screw 28 for attaching the awning panel 11 to the pivot 10 (FIG. 7 (A)). After inserting the weight 27 into the inner bottom surface of the pivot 10 of the square pipe, the weight 27 is screwed together with the awning panel 11 (FIG. 7 (B)), or the weight 27 is placed on the awning panel 11 and screwed from below. It is also possible to fix it by such means (Fig. 7 (C)). In any case, by arranging the center of gravity below the center of rotation of the pivot 10 and on the vertical axis passing through the center of rotation, the awning panel 11 rotated by the wind generates a restoring force. can do.

According to the awning of the present embodiment configured as described above, when there is no or almost no wind, the movable awning 6 returns to the original position by the force of the restoring means (spring 24 or weight 27) 12. Therefore, the gap between the awning panel 11 and the awning panel 11 is closed to the minimum width, the sunlight is blocked, and the sunlight slightly intersects the light and the shadow entering through the gap becomes sunlight like sunlight through the sun, and under the awning panel 11. Create a comfortable space.

Then, when a wind occurs, a gap between the awning panel 11 and the awning panel 11 is opened so that the wind can escape. That is, when the wind acts, the awning panel 11 flutters to parry the wind. For this reason, the area that receives the wind is reduced, the blow-up load is reduced, or the blow-down load is reduced, and the awning is less likely to be blown or knocked down. Moreover, since the rotation of the awning panel 11 fluctuates according to the fluctuation of the wind strength, the wind can be released as appropriate without being left open or closed. In addition, the gap between the awning panel 11 and the awning panel 11 changes, and the sun shines on the awning panel 11 and reflects it, so that the space under the awning panel 11 changes to the brightness and the position where the sun shines. That is, since it gives fluctuations, it is possible to give the comfort of natural sunlight through the trees. Here, since the wind is passed by the rotation of the awning panel 11, it is possible to reduce the burden on the pivot 10 and the beam 3 and the support column 2 that support the pivot 10.

Further, in the present embodiment, since both ends of the pivot 10 of the movable awning 6 are rotatably supported by the bracket 18 fixed to the beam 3, even if the awning panel 11 rotates, the frame contour as the awning No change appears in the roof frame 4. Therefore, the surprise given to the user is small. In other words, it is unlikely to surprise users that the awning may have broken. Rather, since the movable awning 6 sways partially or entirely according to the flow of the wind, the flow of the wind can be visualized and a quaint effect can be produced.

Further, when the wind weakens, the awning panel 11 that has been rotated to allow the wind to pass through is automatically returned to the original position by the restoring force, so that the original function as the awning can be fully restored. That is, by forming one large awning surface 7 by arranging a large number of awning panels 11 side by side, it is possible to significantly block the sunlight. Moreover, it can function as a awning that is soft like sunlight through the trees and allows sunlight to enter.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be performed without departing from the gist of the present invention. For example, in the above-described embodiment, all the awning panels 11 fixed to one pivot 10 are rotated at the same time, but the present invention is not particularly limited to this, and the fixed pivot 10 is not shown. Each awning panel 11 may be independently rotated or not rotated around the awning panel 11.

Further, the awning according to the above-described embodiment is effective to be applied to a temporarily installed awning, but this does not mean that it cannot be applied to a permanently installed awning. For example, even when the support column 1 is embedded in the ground or a stationary foundation method of fixing with anchor bolts is adopted and applied to a permanently installed awning, the awning panel 11 has the advantage of rotating and the wind can pass through, and sunlight through the trees. It does not lose the advantage of being able to produce such sunlight.

Further, the awning of the present invention is not limited to the flat roof (roof on a flat surface without slope) type paragola type in which the awning panel 11 is arranged in a plane as in the above-described embodiment, and is not limited to, for example, a slope (gable). It is also possible to realize a dome-shaped awning in which the awning panel 11 is arranged on a roof, a hipped roof, a one-sided roof, a square roof, etc.).

Further, in the above-described embodiment, the description has been mainly given with an example in which the columns 1 and the beams 3 are applied to a rectangular paragola type awning having four columns each, but the number and shape of the columns, beams, etc. Is not particularly limited, and the number of columns can be three, five, or more, and if the roof frame 4 has a structure capable of supporting the pivot 10, the four beams 3 are formed into a rectangular parallelepiped shape. It is not limited to the assembled one. For example, in the case of an annular awning, the pivots 10 are arranged, for example, radially and hung between the inner annular frame and the outer annular frame (ie, the roof frame is composed of the inner annular frame and the outer annular frame). The awning panel 11 fixed to each pivot 10 becomes larger toward the outside in the radial direction and becomes smaller toward the inside in the radial direction. Then, the shape and arrangement are determined so that the adjacent awning panels 11 do not interfere with each other during rotation. Further, the awning panel 11 is hung between the inner arc-shaped frame and the outer arc-shaped frame, and the awning panel 11 fixed to each pivot 10 becomes larger as it goes outward in the radial direction, and goes inward in the radial direction. It will be small enough. Then, the shape and arrangement are determined so that the adjacent awning panels 11 do not interfere with each other during rotation.

In the above-described embodiment, the description has been mainly given with an example configured as a pergola type awning, but the present invention is not particularly limited to this, and for example, there is no awning, that is, a support column, which is attached to the wall surface of the building frame in the shape of an eaves. It may be configured as a awning. Also in this case, for example, one side (beam) of a rectangular roof frame is fixed to the wall surface of the building frame to form an eave, or a roof composed of two beams protruding from the wall surface of the building frame in an eaves shape. The awning may be configured so that the pivot is supported by a frame or a roof frame composed of three beams including a beam connecting the tips of two beams protruding in an eaves shape.
