Application of Article 30, Paragraph 2 of the Patent Act Published on October 21, 2020 at Ruby no Sato, the exhibition hall of Takano Co., Ltd.

The present invention relates to a sunshade. More specifically, the present invention relates to a sunshade particularly suitable for outdoor use.

Conventionally, as a sunshade that is permanently installed outdoors, for example, a paragola has a sunshade sheet that is slidably supported on a rectangular roof frame that is the ceiling of a framework made up of four pillars and four girders. There are several types of awnings (Patent Document 1).

Japanese Patent Application Publication No. 2014-169563

Since this pergola type awning is always installed outdoors, it usually has a strong frame structure and is required to be firmly fixed to the ground as a countermeasure against strong winds. Moreover, sunshades are easily affected by wind, and when used outdoors, sufficient measures must be taken against gusts and strong winds. For this reason, on days when strong winds are expected to blow, you can take precautions such as moving the sunshade sheet to one corner of the roof frame to make it less affected by the wind, but if a strong wind suddenly blows, In such cases, there is no time to clean up the sunshade sheet, and there is a risk that the fabric and frame may be damaged. In addition, the sunshade sheet is constructed by connecting multiple small sheet materials with a sunshade frame that moves along the rails of the framework girders, so it is strong even if the sunshade sheet is placed close to one corner of the roof frame. There is also the risk that wind will cause the frames to collide with each other, causing noise.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sunshade that satisfactorily functions as a sunshade while also having a wind ventilation function to deflect the wind when it is exposed to the wind.

In order to achieve this object, the sunshade according to the invention according to claim 1 includes a support frame having a roof frame, a pivot shaft rotatably or fixedly installed across the roof frame, and a support frame fixed to the pivot shaft. A plurality of panels that are rotatably supported and rotatable about a pivot axis, and a restoring means that returns the panels to a horizontal position when the panels are not exposed to wind, and the panels rotate about the pivot axis without interfering with each other. A sunshade surface is made up of a collection of multiple panels placed with as much space as possible, and when the panels are not exposed to the wind, they are kept in a horizontal position, and when they are exposed to the wind, they rotate and change direction to deflect the wind. That's what I do.

Here, it is preferred that the panel is fixed to a pivot, that the pivot is rotatably supported on the roof frame, and that the panel rotates together with the pivot.

In addition, the restoring means is a spring, which is provided with oppositely wound springs at both ends of the pivot shaft, and applies a spring force that holds the panel horizontally, and allows the pivot shaft to rotate when it is exposed to wind. When it is seated, it is preferable that the spring force restores the panel to a horizontal position.

Further, it is preferable that the restoring means is a weight that sets the center of gravity below the center of rotation of the pivot, and 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 on which the wind blows rotates around its axis to deflect the wind, which reduces the blow-up load or the blow-down load and prevents the support from being blown away. It becomes difficult to be defeated or defeated. Moreover, since it is possible to pass the wind without being directly affected by it, it is possible to reduce the burden on the panels and axis and avoid damage. In addition, since the panels deflect the wind by rotating, the panels do not flap in the wind and come off the axis and scatter, making it highly safe. Furthermore, since the panel rotates around a pivot mounted on the roof frame, the panel does not collide with or come into contact with the user under the awning.

What's more, when the wind subsides, the restoring means will restore the panels to their original positions, allowing them to fully regain their original function as sunshades. In other words, according to the sunshade of the present invention, when there is no wind or there is a light breeze, the gaps between the panels are closed to form a sunshade surface, so that it can function as a sunshade that blocks strong direct sunlight, and The panels are swayed by the wind, allowing the sunlight to shine through the trees like sunlight filtering through the trees, allowing the space to receive soft sunlight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail below based on embodiments shown in the drawings.

FIGS. 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 sunshade according to this embodiment includes a support frame 1 having a roof frame 4 and a movable sunshade 6 that is constructed on the roof frame 4 and forms a sunshade surface 7.

The movable sunshade 6 includes a pivot shaft 10 installed across the roof frame 4, a plurality of sunshade panels 11 supported by the pivot shaft 10 and rotatable around the pivot shaft 10, and when the sunshade panel 11 is not exposed to wind. A restoring means 12 for returning the sunshade panel 11 to a horizontal position, and the sunshade panel 11 is arranged with a gap such that the sunshade panel 11 can rotate around the pivot 10 without interfering with each other, and the sunshade panel 11 is an aggregate of a plurality of sunshade panels 11. 7, the sunshade panel 11 is kept in a horizontal position when it is not exposed to wind, and when it is exposed to wind, it rotates and changes direction to deflect the wind.

In the case of this embodiment, the support frame 1 is, for example, a corner where four pillars 2, four beams 3 supported at both ends by the pillars 2, and beams 3 in two directions perpendicular to the pillars 1 intersect. It is assembled by connecting the pillar 1, the beam 3, and the corner joint 5, respectively. Here, a roof frame 4 is constructed by assembling four beams 3 into a rectangular parallelepiped shape, and the roof frame 4 is supported at a desired height by four pillars 2. Note that in this specification, the roof frame refers to any structure that can support the pivot shaft 10, and is not necessarily limited to a closed structure by connecting four beams as in this embodiment. do not have.

Here, the strut 1 may be a single extruded aluminum alloy or square pipe as shown in FIGS. 2 and 3, but in some cases, multiple struts (not shown) can be expanded and contracted. It may be combined with a telescopic structure (telescopic structure) that can be fixed at any position using a connector. For example, by combining rectangular tubes of different sizes to form a telescopic structure (telescopic structure) in which one prism is slidably connected to the other prism, the support column 1 can be expanded and contracted. It's okay to be beaten. From the perspective of expansion and contraction, the nested pillars may have either rectangular cylinder made large, but preferably have a nested structure in which the lower prism can fit into the upper prism, that is, the inside of the upper prism. The outer dimensions of the lower prisms are made narrower than the actual size of the prisms, so that rainwater does not enter through the gap between the upper prisms and the lower prisms and accumulate.

The corner joint 5 surrounds the corner where the column 1 and the beam 3 are perpendicular to each other, and is connected to the column 1 and the beam 3 by connecting the three orthogonal surfaces to the column 1 and the beam 3 with bolts or the like. 3 are interconnected. Although not shown, angles are welded to the inside of each of the three faces of the corner joint 5 at intervals of approximately the same width as the struts 1 or beams 3, and the rising edges of the angles (fixed) The position can be regulated by inserting a support 1 or a beam 3 into the space between the side perpendicular to the surface where the support is located and the inner surface of the corner joint 5 facing thereto.

The method of fixing the pillar 1 may be to construct a foundation and fix it, but it is not particularly limited to this, and it is preferable to fix it with a weight or with an anchor. For example, the lower end of the column 1 is provided with a load receiving portion 8 that protrudes laterally from the column 1 and receives a weight 9. The support 1 may be fixed by placing a weight 9 on the load receiving portion 8. Here, the load receiving part 8 not only carries the weight 9 but also has the function of widening the installation area of the support column 1 and making it difficult to fall down.

The weight 9 is, for example, a split ring made of semi-cast iron, which is combined to surround the support 1 to form one ring (weight assembly), and further stacked on top of it to form a cylindrical shape. . The weight of the weight 9 is adjusted by increasing or decreasing the number of stacked weight assemblies. Of course, the weight 9 is not limited to the above-mentioned cast iron, but may also be made of concrete or a plastic container that can be used as a weight by injecting water, etc., and its shape is not limited to the half-ring shape, but may also be rectangular. It may also be a U-shaped or U-shaped block. Since the support only needs to be fixed by placing a weight 9 on it, there is no need for large-scale construction work such as foundation work. Therefore, it is possible to assemble and disassemble easily and quickly, making it 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 it rotates around the axis 10. Specifically, the size of the awning panel 11 in this embodiment depends on the height of the support column 2. In this case, for example, they are small approximately square panels with a side of about 30 to 40 cm and the 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 this embodiment, five approximately square sunshade panels 11 of, for example, approximately 35 cm x 35 cm are connected and fixed at regular intervals relative to one pivot 10, forming a row. It is arranged and spanned between the beams 3 of the roof frame 4 to be rotatably supported. As a result, the 25 sunshade panels 11 are arranged within the 3m x 3m roof frame 4 so as not to interfere with each other and with the beam 3 when rotating, forming one sunshade surface 7. There is.

In the case of this embodiment, by fixing the sunshade panel 11 to the shaft 10 with screws or the like so that the shaft 10 is arranged on the diagonal of the approximately square sunshade panel 11, The shape is such that triangular wings protruding in the lateral direction) are formed intermittently, but the configuration is not particularly limited to this, and the orientation of the arrangement and the method of fixing are not particularly limited to this. For example, as shown in FIG. 8, a rectangular strip-shaped sunshade panel 11 that is slightly shorter than the pivot 10 and has a width that leaves a small gap between the pivots 10 on both sides is fixed to the pivot 10. You may also do this. Further, as shown in FIG. 9, for example, square or rectangular sunshade panels 11 having a length slightly shorter than twice the interval between adjacent pivots 10 are arranged in a staggered manner between a plurality of pivots 10. It's okay. Of course, the number of sunshade panels 11, the arrangement interval, etc. are determined as appropriate, but the gap is set so that when the sunshade panel 11 rotates around the axis 10, there will be no interference with the surrounding sunshade panels 11. . Here, it is preferable that the gap does not become too large and the amount of sunlight leaking between the sunshade panels 11 becomes too large.

Although the sunshade panel 11 is not limited to a particular material, it is preferable to use a polycarbonate panel, which has excellent weather resistance and strength, for example. In this embodiment, all the sunshade panels 11 have the same size and the same shape, but depending on the case, some or all of the sunshade panels 11 may have different sizes or may have different designs. When coloring or designing the sunshade panel 11, it is possible to enjoy the effect of changing the design or color scheme by rotating the sunshade panel 11.

Furthermore, it is not necessary that all the sunshade panels 11 be rotatably supported at all times, and some of the sunshade panels 11 may be fixed arbitrarily or always fixed. For example, the rotation of the sunshade panel 11 may be restricted by fixing the pivots 10 in every other row, or a portion of the pivots may be made fixable as necessary. In this case as well, by rotating some of the remaining sunshade panels 11, it is possible to achieve the effect of venting the wind and creating a space similar to sunlight filtering through the trees.

Further, in addition to the rotating sunshade panel 11, a non-rotating sunshade panel 13 may be provided. For example, a fixed sunshade panel 13 may be provided that fills the space near the roof frame 4 (ie, the space between the rotating sunshade panel 11 and the roof frame 4). In the case of the embodiment shown in FIG. 1, a saw-blade-shaped fixed sunshade panel 13 as shown by the imaginary line is arranged so as to protrude inward from the roof frame 4, and is fixed around the rotating assembly of sunshade panels 11. The rectangular roof frame may be completely filled with the sunshade panels 11 and the fixed sunshade panels 13 so as to be surrounded by the sunshade panels 13. In this case, it is possible to shade approximately the same area as a paragola-type awning made of canvas, and provide shade similar to sunlight filtering through foliage.

In this embodiment, a square pipe made of extruded aluminum is used as the pivot 10, for example. By arranging and fixing a plurality of sunshade panels 11 on the same plane by using square pipes, it becomes easy to align the orientation and horizontal posture of the sunshade panels 11. In the case of this square pipe/pivot 10, for example, as shown in FIGS. 4 to 6, by providing rotating shaft portions 14 at both ends, it is possible to rotatably attach it to the bracket 18 on the beam 3 of the roof frame 4. It is said that Of course, the pivot 10 is not limited to a specific support structure as long as it can be rotatably attached to the roof frame 4.

In the case of this embodiment, the rotating shaft portion 14 is attached to the open end of the pivot shaft 10 via a U-shaped fixing plate 15 that is fixed non-rotatably to the pivot shaft 10 of the square pipe, as shown in FIGS. 4 and 5. It is being The fixing plate 15 is inserted into the square pipe (pivot 10) by inserting the leg parts (two parallel surfaces) at both ends bent inward, and then fixed to the two sides of the square pipe with screws 29, so that the pivot 10 is fixed. is attached to the open end of the The fixed plate 15 and the rotating shaft part 14 are fixed in a non-rotatable manner by fixing them with two screws 17 with the end surface of the rotating shaft part 14 in contact with the bottom between the legs of the fixed plate 15. has been done. Therefore, the pivot 10 is rotatably supported by a bracket 18 fixed to the beam 3 via the rotating shaft portions 14 at both ends. Incidentally, a slit 16 is provided at the tip of the rotating shaft portion 14, into which one end of the spiral spring 24 is hooked.

The bracket 18 is, for example, an L-shaped plate material (angle material), and a vertically rising shaft bearing part 19 has a circular hole 21 through which the rotating shaft part 14 passes, and a bottom part 20 has screws (for fixing it to the beam 3). A long hole 30 (not shown) is provided. The rotating shaft part 14 passes through the circular hole 21 of the bracket 18 with an oil-less (oil-free, self-lubricating) bushing, for example, a cylindrical resin sliding bearing 22 fitted therein, and is then fitted with a C-shaped retaining ring 23. 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 this embodiment, it is constituted by, for example, a simple rectangular cylinder. Therefore, consideration is given to fixing the bracket 18 by applying, for example, a back metal 31 and fastening it with screws.

In the case of this embodiment, the restoring means 12 is incorporated in the rotating shaft portion 14 . In this embodiment, the restoring means 12 uses a spring, for example, a spiral spring 24. One end of the spiral spring 24 is passed through the slit 16 at the tip of the rotating shaft portion 14 and hooked thereon, while the other end, which is folded back into a rectangular shape, is attached to two parallel screws 25 screwed to the bracket 18. It is hooked onto the screw 25 so as to pass through the gap. The spiral springs 24 are used in combination so that spiral springs with the same winding direction wind in opposite directions when attached to the rotating shaft portions 14 at both ends of the pivot shaft 10. That is, a left-handed spiral spring is attached to one end of the pivot 10, and a right-handed spiral spring is attached to the other end, so that they are biased in opposite directions. Therefore, the pivot shaft 10 is always biased by spring forces in opposite directions, so that no matter which direction the pivot shaft 10 rotates, the sunshade panel 11 screwed to the bottom is balanced in a horizontal position. 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 to cover the rotating shaft portion 14, the spiral spring 24, the C-shaped retaining ring 23, the bearing oilless bushing 22, etc., and protect them from dust.

Of course, the pivot 10 is not limited to a square pipe, but may be a round pipe or a round bar. In this case, the trouble of attaching the rotating shaft part can be saved and the structure can be simplified, but when attaching the sunshade panel 11, it is necessary to take into consideration misalignment and the like. On the other hand, when using a round pipe or a round bar as the pivot 10, it is possible to fix the sunshade panel 11 to the round pipe (not shown) and then attach it to the pivot 10 with a collar spacer interposed in the axial direction ( (double pipe structure), each sunshade panel 11 can be freely rotatably supported. In this case, since the wind parry is the unit of the sunshade panel 11, more detailed adjustment is possible, and the movement of the sunshade panel 11 is also rich in variation. It becomes possible to reproduce it.

Furthermore, as the restoring means 12 of the movable sunshade 6, a weight 27 may be used, for example. For example, as shown in FIG. 7, the weight 27 may be attached to the bottom side of the shaft 10 with the sunshade panel 11 interposed using the screws 28 that attach the sunshade panel 11 to the pivot 10 (FIG. 7(A)), or Insert the weight 27 into the inner bottom of the shaft 10 of the square pipe and then screw it onto the sunshade panel 11 (Fig. 7(B)), or place the weight 27 on top of the sunshade panel 11 and screw it from below. It is also possible to fix it by, for example, (FIG. 7(C)). In any case, by locating the center of gravity below the rotation center of the pivot shaft 10 and on the vertical axis passing through the rotation center, the sunshade panel 11 that rotates due to the wind generates a force to restore its original shape. can do.

According to the awning of this embodiment configured as described above, when there is no or almost no wind, the movable awning 6 returns to its original position by the force of the restoring means (spring 24 or weight 27) 12. Therefore, the gap between the sunshade panels 11 is closed to the minimum width, sunlight is blocked, and the sunlight that enters through the gap becomes like sunlight filtering through the leaves, where the light and shadow intersect. Create a comfortable space.

Then, when the wind arises, a gap between the sunshade panels 11 opens, allowing the wind to escape. That is, when the wind acts, the sunshade panel 11 deflects the wind. As a result, the area exposed to the wind is reduced, and the blow-up load is reduced, or the blow-down load is reduced, making it difficult for the awning to be blown away or knocked down. Furthermore, since the rotation of the sunshade panel 11 fluctuates in response to changes in the strength of the wind, the sunshade panel 11 does not remain open or remain closed, allowing the wind to escape as appropriate. In addition, the brightness of the space under the sunshade panel 11 and the position of the sunshade panel 11 change due to changes in the gap between the sunshade panels 11 and sunlight hitting and reflecting on the sunshade panel 11. In other words, since it provides fluctuation, it can provide a comfortable feeling similar to natural sunlight filtering through the trees. Here, since the wind is deflected by rotating the sunshade panel 11, it is possible to reduce the burden on the pivot shaft 10 and the beams 3 and struts 2 that support the pivot shaft 10.

Further, in this embodiment, since both ends of the pivot shaft 10 of the movable sunshade 6 are rotatably supported by the bracket 18 fixed to the beam 3, even if the sunshade panel 11 rotates, the frame outline as a sunshade does not change. No change appears in the roof frame 4. Therefore, there are fewer surprises for the user. In other words, users are less likely to be surprised that the sunshade is broken. Rather, since the movable sunshade 6 swings partially or entirely in response to the wind flow, the wind flow can be visualized and an attractive effect can be created.

Furthermore, when the wind weakens, the sunshade panel 11, which has been rotated to allow the wind to pass through, automatically returns to its original position due to its restoring force, allowing it to fully regain its original function as a sunshade. That is, by arranging a large number of sunshade panels 11 to form one large sunshade surface 7, sunlight can be largely blocked. What's more, it can function as a sunshade, allowing sunlight to filter in softly like sunlight filtering through the trees.

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

Furthermore, although it is effective to apply the awning according to the above-described embodiments to a temporarily installed awning, this does not mean that it cannot be applied to a permanently installed awning. For example, even if a stationary foundation construction method in which the pillars 1 are embedded in the ground or fixed with anchor bolts is adopted and applied to a permanently installed awning, there are advantages such as the rotation of the awning panel 11 to allow wind to pass through, and the advantage of sunlight filtering through the trees. This does not mean that you lose the advantage of being able to produce such sunlight.

Further, the sunshade of the present invention is not limited to the paragola type of a flat roof (a flat roof with no slope) in which the sunshade panels 11 are arranged in a flat manner as in the above-mentioned embodiments, but for example, the sunshade of the present invention is not limited to the paragola type of a flat roof (a flat roof with no slope), but is It is also possible to realize a dome-shaped sunshade in which the sunshade panel 11 is arranged on the roof, hipped roof, single-sided roof, square roof, etc.).

Furthermore, in the above-described embodiment, the explanation was mainly given as an example in which the pillars 1 and beams 3 are applied to a rectangular paragola type awning with four each, but the number and shape of the pillars and beams etc. is not particularly limited; the number of pillars can be three, five, or more, and if the roof frame 4 has a structure that can support the pivot shaft 10, the four beams 3 can be arranged in a rectangular parallelepiped shape. It is not limited to assembled items. For example, in the case of an annular sunshade, the pivots 10 are arranged radially, for example, and span between an inner annular frame and an outer annular frame (i.e. the inner annular frame and the outer annular frame form the roof frame). ), and the sunshade panels 11 fixed to each pivot 10 become larger as they move toward the outside in the radial direction, and become smaller as they move toward the inside in the radial direction. The shape and arrangement are determined so that adjacent sunshade panels 11 do not interfere with each other during rotation. In addition, the sunshade panel 11, which is stretched between the inner arc-shaped frame and the outer arc-shaped frame and is fixed to each pivot 10, becomes larger as it goes radially outward, and increases in size as it goes radially inward. The size is relatively small. The shape and arrangement are determined so that adjacent sunshade panels 11 do not interfere with each other during rotation.

In the above-mentioned embodiment, the description was mainly given of an example configured as a pergola-type awning, but the invention is not limited to this. For example, the awning is attached to the wall of a building frame in the form of an eave, that is, it does not have supports. It may also be configured as a sunshade. In this case as well, for example, one side (beam) of a rectangular roof frame is fixed to the wall of the building frame to form an eave, or a roof is constructed of two beams projecting like an eave from the wall of the building frame. The awning may be configured such 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 projecting like an eaves.
