  However, since it is an open / close mechanism that only translates rectilinearly while the rectangular shade frame is folded from the end in a rectangular roof frame unit, the novelty of the shade sheet and lack of fun, and the left and right of the hanging pipe If the movement of the sliders at both ends can not be synchronized, it will be difficult to easily open and close with light operating force.

  In addition, when the sunshade is stored to take in sunlight, the folded sunshade sheet is gathered to one end of the awning by the parallel movement of the hanging pipe, so that a large area where sunlight is shielded by the rectangular fold sunshade sheet is generated. There is.

  An object of the present invention is to provide a free standing awning that can store a sun protection sheet compactly and does not take up a space at the time of storage.

  In order to achieve the above object, a freestanding awning according to the invention of claim 1 comprises a frame unit provided with a girder frame having a circular or annular guide rail portion, a plurality of awning frames as a framework, and the frame. The rotation is achieved by bundling a proximal end of the sunshade frame and rotatably connecting the end portions of the sunshade frame with a single rotary shaft. And a sunshade sheet which is opened and closed in a fan-like manner about an axis, and the sunshade sheet is slidably suspended in the circumferential direction along a guide rail portion of the girder frame via slide means at an outer peripheral end thereof. And the end portions on the inner circumferential side are sequentially distributed to different height positions of the rotation axis disposed at the center of curvature of the girder frame via the connection plate and stacked one on top of the other. Is rotatably coupled, the tilt angle of the awning frame is different in next to each other, characterized in that in the vicinity of the rotating shaft as a main are distributed in the vertical direction so as not to interfere with each other.

  In the self supporting awning according to claim 2, an offset amount for each connection plate corresponding to a different connection position with respect to the rotation axis in each area of a plurality of connection plates sequentially distributed to different areas of the rotation axis is set, The height position of the base end of the sunshade frame for each area is arranged at the same height, and the sunshade frame has the same number of sunshade frame slopes as the number of areas.

  In the self supporting awning according to the third aspect of the invention, the connection plate supporting the base end portion on the inner peripheral side of the awning frame is alternately distributed to the upper side or lower side region of the rotary shaft and different height positions And is rotatably supported.

  Further, in the self-supporting awning according to claim 4, the girder frame is divided into a plurality of sections, each section is provided with a sun protection sheet, and the sun protection frames of the sun protection sheets are connected by one endless annular rope It is characterized in that it is opened and closed.

  In the self-supporting awning according to a fifth aspect of the present invention, the plurality of sunshade frames have different inclination angles next to each other, and the entire inner peripheral side is inclined so as to be lower than the outer peripheral side.

  In the free standing awning according to claim 6, the rainwater receptacle is disposed inside the awning frame, and the rainwater receptacle and the vertical weir disposed along the column are connected by a weir to drain around the column It is a thing.

  A self-standing awning according to claim 7 is characterized in that the opening / closing operation means comprises a rope connected to the sun protection sheet and a drawing means for drawing the rope and causing it to hang in the vicinity of the support.

  According to the self-supporting awning according to claim 1, the base end sides of a plurality of sunshade frames connected by a single rotation shaft in a fan-shape are rotatably connected to be distributed sequentially and stacked at different height positions. Since the adjacent sunshade frames are arranged in the vertical direction so that they do not interfere with each other in the vicinity of the rotation axis, the sunshade frames adjacent to each other on the outer peripheral end are made close without opening. We can store compactly and do not take up space at the time of storing. Therefore, the area for blocking the sunshine when the sunshade sheet is folded and stored can be made smaller than that when folded into a rectangle by the parallel movement of the hanging pipe as in the awning described in Patent Document 1.

  In addition, it is possible to provide the awning of the novel novel movement in which the sunshade sheet opens and closes in a fan shape in the horizontal plane along the annular frame around the rotation axis. In addition, since the fan-shaped opening and closing is performed around the rotation axis, the opening and closing is smooth and the opening and closing can be easily performed with a light operating force.

  Further, according to the self supporting awning according to claim 2, the height positions of the base end portions of the plurality of connection plates sequentially distributed to the different regions of the rotation axis are the same as the number of regions and the inclination of the sunshade frame Since they are arranged in the same number of stages as the above, it is possible to eliminate the problem of interference between the sunshade frames without requiring the storage height near the rotation axis, which is a key axis.

  Moreover, according to the self supporting type awning of Claim 3, since the base end part by the side of the inner periphery of a sun protection frame is alternately distributed to two area | regions of the upper stage side and the lower stage side and the problem of interference is eliminated, We can store compactly and do not take up space at the time of storing.

  Further, according to the self-supporting awning described in claim 4, it is possible to realize an interesting movement in which a plurality of sunshade sheets are simultaneously opened and closed in a plurality of sections, and the sunshade sheets are simultaneously opened and closed in each section. (Full opening) or storing (full closing) does not take time. In addition, at the time of deployment, a plurality of awnings arranged in an annular shape can constitute one large circular awning as a whole.

  Further, according to the self-supporting awning according to claim 5, since the inclination angles are different from each other and the entire inner peripheral side is inclined so as to be lower than the outer peripheral side as a whole, rainwater from the outer peripheral edge of the sunshade sheet Can be prevented from falling. This prevents rainwater from falling like a waterfall from the periphery of the awning, for example, when it rains heavily and enables awnings to be connected continuously.

  According to the self-supporting awning according to claim 6, the rainwater receptacle is disposed inside the awning frame, and the rainwater receptacle and the vertical weir disposed along the pillar are connected by a horizontal weir so as to drain around the pillar Therefore, it is possible to prevent rain water from falling from the outer peripheral edge of the awning sheet. In this way, awnings can be connected continuously by preventing rainwater from falling like a waterfall from the periphery of the awning and draining it near the ground in the vicinity of the support when it rains heavily or the like.

  According to the self-supporting awning of claim 7, the opening / closing operation means can be easily operated since it comprises the rope connected to the sun protection sheet and the drawing means for drawing the rope and making it hang down in the vicinity of the support.

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

  An example of embodiment of the free-standing awning of this invention is shown in FIGS. In this embodiment, the direction in which the sunshade sheet 4 is expanded (expanded) is forward, the direction in which it is stored (closed) is backward, and the outside in the radial direction is the outer periphery, and the inside in the radial direction is the inner periphery or the base end. Call.

  As shown in FIGS. 1 and 2, the free standing awning according to the present embodiment forms a ceiling that can be opened and closed by pivoting the sunshade sheet 4 along a toroidal frame 1 so as to spread a fan in a horizontal plane. Operating the tow rope 12 of the opening / closing operation means provided with a fan-shaped sunshade sheet 4 for each fan-shaped section between the columns 2 and connected to the top sunshade frame 18 of the sunshade sheet 4 for each section Thus, the three-zone shading sheet 4 is configured to be opened and closed at the same time. That is, the awning of the present embodiment arranges three fan-shaped sunshade sheets 4 in an annular shape to constitute a circular awning (sunshade) as a whole, and one opening / closing operation means sectoric sunshade for each section The seat 4 is configured to open and close at the same time.

  The annular frame 1 is, for example, as shown in FIG. 7, an arc-shaped girder frame 3, a support 2 for supporting both ends of the girder frame 3, and a support arranged at the center (hereinafter referred to as a central suspension support 7). And horizontal structural members (hereinafter referred to as beam frame 5) and diagonal structural members (hereinafter referred to as beam frame 5) radially arranged around the central support columns 7 and radially connecting the central support columns 7 and the peripheral support columns 2. , Called rafter frame 6). In the case of this embodiment, the annular frame 1 is configured by circumferentially connecting three fan-shaped sections partitioned by the three girder frames 3 and the three columns 2 supporting the respective ends, and in each fan-shaped section A foldable sunshade sheet 4 is provided so as to be openable and closable. The girder frame 3 of each sector section has an arc shape, but has an arc shape with the rotation axis 20 provided for each sector section as the center of curvature, and is the center of the entire annular frame 1 The radius of curvature is different from a circle whose center of curvature is the center of the central support post 7. That is, instead of forming a perfect circular ring having one curvature center, a non-perfect circular ring having three curvature centers obtained by connecting three arcs is formed.

  The support 2 is formed of, for example, a square pipe having a substantially square cross-sectional shape, and the girder frame 3 is connected to two opposing surfaces in the circumferential direction, that is, side surfaces, and an inner (radial inside) surface orthogonal thereto. The beam frame 5 is connected to. For example, as shown in FIG. 7, a bracket 8 having a grate frame 3, a beam frame 5, and a square or square tubular bracket fitted with the rafter frame 6 is fixed in advance to the support 2 and the central suspension support 7 side. Are fixed by bolting in a state of being fitted to the end opening of each frame. Furthermore, for example, a triangular reinforcing plate (triangular bracket 9) is applied to the joint surface portion of the support 2 and the girder frame 3 to be connected to each other and reinforced. Further, also between the column 2 and the beam frame 5, for example, a triangular reinforcing plate (triangular bracket 10) is applied to the joint surface and connected and mutually reinforced. As a result, the support 2 and the girder frame 3, the beam frame 5 and the rafter frame 6 are fixed (rigidly connected) to each other, and a central suspension support 7 is supported to form a rigid frame structure.

  A storage cover 11 is provided at a position where the shading sheet 4 in each section is folded and gathered, which prevents the shading sheet 4 in the stored state from getting wet, sunburned or soiled with dust (FIG. 1 And Figure 2). The storage cover 11 is fixed to the beam frame 5 and the girder frame 3 across the girder frame 3 and the girder frame 5 in a floating state via a spacer (not shown). The tow rope 12 is provided to form a gap through which the tow rope 12 passes. The storage cover 11 has, for example, a substantially triangular shape, covers and hides the sunshade frame 18 at the top of the sunshade sheet 4 of the section next to the sunshade sheet 4 in the stowed state. It is sized to reach the inside of the As a result, the sunshade sheet 4 to be stored is covered and protected, and a gap is not generated between the sunshade sheet 4 and the beam frame 5 when the sunshade sheet 4 is expanded. It is considered that raindrops do not leak inside.

  For example, as shown in FIG. 7C, the central suspension column 7 has an irregular hexagonal cross-sectional shape in which a wide surface and a narrow surface are alternately formed, and three central The rafter frame 6 and the beam frame 5 are rigidly connected to each other on a relatively large plane via the bracket 8, and the three relatively small planes between them are the main points of the sunshade sheet 4 which opens and closes in a fan shape. A bracket 17 for supporting the rotary shaft 20 is attached. The bracket 17 has, for example, a U-shape having an upper side and a lower side, and the rotation shaft 20 of the sun protection sheet 4 is supported between the upper side and the lower side.

  A shallow funnel-shaped rainwater receptacle 13 is suspended from the central suspension post 7 (see, for example, FIGS. 6 and 9). At the center of the rainwater receptacle 13, a water collector 40 in which a horizontal weir 14 is penetrated is provided, and it is provided so as to collect the rainwater collected on the rainwater receptacle 13 and pour it into the horizontal weir 14. A horizontal weir 14 is connected to the water collector 40 with a predetermined inclination, and is further connected to the vertical weir 15 attached to the inner side of the optional column 2, and rainwater that falls on the sun protection sheet 4 and the roof 16 Are collected in the rainwater receptacle 13 and then conducted to the ground via the weir 14 and the weir 15. This prevents rainwater from falling like a waterfall from the edge of the awning when it rains heavily, and enables a succession of awnings. In the case of the present embodiment, the rainwater receiver 13 is suspended by being connected to the bracket 17 that supports the rotary shaft 20 by the hanger 40a, but the support structure is not particularly limited to this, for example, the central suspension It may be provided so as to be directly suspended via the hanger 40 a on any of the planes of the support 7 arranged in a hexagonal shape, for example, three planes arranged at equal intervals.

  In addition, a conical roof 16 is placed on the top of the central support post 7. The roof 16 has a size slightly projecting radially outward from the inner peripheral edge of the sheet-like member 19 of the sun protection sheet 4, for example, and is arranged to cover the inner peripheral side of the sun protection sheet 4 and the storage cover 11 . As a result, the rainwater received by the roof 16 is dropped to a position near the inner peripheral edge of the awning 4 or the storage cover 11 and is further flowed to the rainwater receiver 13.

  In the case of the present embodiment, the girder frame 3 has a guide rail portion 3b which holds the slide means 21 at least on the outer peripheral end side of the sunshade frame 18 and is movably supported in the circumferential direction. The back-to-back joining of a square pipe 3a made of a rectangular shape of a cocoon and a channel material constituting the guide rail portion 3b is used. An example of the cross section of the girder frame 3 is shown in FIG. The channel material / guide rail portion 3b is disposed and welded in such a manner that the opening is directed inwardly in the radial direction of the corner pipe portion 3a, that is, toward the central support post 7. In the case of the present embodiment, a recessed portion is formed on the inner surface of the square pipe portion 3a facing the channel material 3b, and the guide rail portion 3b is fitted into the recessed portion so as to provide a hook in the vertical direction. It is done. In the present embodiment, although the girder frame 3 is configured by combining the channel material 3b and the square pipe 3a, the present invention is not particularly limited to this, and the guide rail portion 3b is an extrusion molded material integrally formed in advance. It may be configured.

  Between the central portion of the arc-shaped girder frame 3 and the central suspension support 7, as shown in FIG. 1, a suspension wire 29 is stretched so that the central portion of the girder frame 3 is not bent. . One end, for example, the radially outer end of the suspension wire 29 is fixed to a bracket 30 screwed to the outer circumferential surface of the girder frame 3, while the other end, ie, the radially inner end, is fixed to the central suspension support 7. Hook 31 is hooked. Then, an appropriate tension is applied by a turnbuckle not shown.

  In the case of the present embodiment, the support 2 is provided so as to be buried directly in the ground and fixed, but the present invention is not particularly limited thereto. For example, a substrate (not shown) is provided on the bottom of the support 2. Fix it by welding or bolting and fix it by bolting the substrate to a structure or foundation or place a cylindrical block such as a half block that can be a weight on the substrate It may be used by fixing it by weight.

  The sun protection sheet 4 is composed of, for example, a plurality of sun protection frames 18 serving as a framework and a triangular sheet-like member 19 stretched between the sun protection frames 18, and the proximal end of the sun protection frame 18 Are connected in a rotatable manner by one rotation shaft 20, which is a main component, and are provided in a fan shape that opens and closes around the rotation shaft 20. The sunshade sheet 4 of the present embodiment is provided so as to have substantially the same size as a fan-shaped section formed between one annular girder frame 3 and the beam frame 5 in the unfolded state. The rotary shaft 20 is disposed in parallel (that is, in the vertical direction) to be openable and closable in the horizontal plane.

  For example, as shown in FIGS. 8 and 10, the sunshade frame 18 has a head portion 18a for suspension and a main body portion 18b for connecting the sheet-like members 19, and the boundary between the head portion 18a and the main body portion 18b Grooves (referred to as necks 18c) into which the clamp members 22 and the claws of the clamp members 26 are inserted are formed in the longitudinal direction in the portion. In the case of the present embodiment, two long grooves 18c in which the sheet-like member 19 is fitted are provided in parallel on the bottom surface of the main body 18b. The cross-sectional shape of each long groove 18c is circular, and the opening of the bottom is narrow. The sunshade frame 18 of such a cross-sectional shape is formed, for example, by extrusion of aluminum. Therefore, the sunshade frame 18 and the sheet-like member 19 insert the cylindrical end 19a of the sheet-like member 19 into the long groove 18c together with the core 19b from the end opening, and the sheet-like member 19 from the opening at the bottom. It is fixed by pulling out. Further, by inserting and fixing one end of the front and rear sunshade sheets 4 to the two long grooves 18b, the front and rear sunshade frames 18 are connected by the sheet-like member 19 stretched between them. In addition, as the sheet-like member 19, although use of a canvas etc. is possible, for example, it is not restricted to this. Further, although not shown, both end openings of the sunshade frame 18 are closed by, for example, a cap not shown.

  The edge of the sunshade sheet 4 configured as described above is hooked on the guide rail portion 3b of the girder frame 3 via the slide means 21 so as to be slidably slidable in the circumferential direction, The different height positions of the rotary shaft 20 arranged at the center of curvature of the girder frame 3 via the connection plate 25 at the side end parts, for example, the upper area (referred to as the upper side 20b) and the lower area (lower side 20a) And rotatably connected so as to be stacked alternately, and the rotary shaft 20 is required, and it is configured to be opened and closed in a fan shape along the girder frame 3 (see FIGS. 9 and 15).

  The slide means 21 is, for example, as shown in FIG. 10, a clamp member 22 for mounting on the sunshade frame 18, a slider 23 suspended in the guide rail portion 3b of the girder frame 3 and movable in the circumferential direction It is comprised with the bolt 24 for fastening as a fastener which connects 22 and the slider 23. As shown in FIG. The clamp member 22 couples the pair of sandwiching pieces 22a sandwiching the head 18a with the pair of left and right sandwiching pieces 22a sandwiching the head (square pipe portion) 18a of the sunshade frame 18, for example, and sandwiches the head 18a. A lower claw 22c which is constituted by a tightening bolt 22b and which is bent inward at the lower end of the holding piece 22a is hooked on a neck 18c of the awning frame 18 and an upper claw 22d which is folded outward on the upper end is a slider 23 In a state of being engaged with the base portion 23c of the second embodiment, it is fastened and fixed to the slider 23 by the fastening bolt 24. The clamping piece 22a is hooked on the base portion 23c by passing the upper claw portion 22d through the slit 23d formed in the base portion 23c of the slider 23, and is provided so as to be adjustable within the width of the slit 23d. By this, when inserting a pair of clamping pieces 22a from the end of head 18c, it is provided so that adjustment of a clearance is enabled.

  The slider 23 is configured of a roller 23 a that can roll along the guide rail portion 3 b of the girder frame 3 and a roller support 23 b that supports the roller 23 a. Here, if there is at least one roller, it can be rolled while the tip of the sunshade frame 18 is hooked on the guide rail portion 3b of the annular girder frame 3, but preferably a plurality, more preferably only the moving direction Also, a plurality of rollers are arranged in the vertical direction. For example, in the case of the present embodiment, four of the two rollers that roll when contacting the ceiling surface of the guide rail portion 3b and the two rollers that constantly contact and roll the bottom surface of the guide rail portion 3b A number of rollers are employed, each spaced apart in the direction of travel, and provided to stabilize the attitude of the sunshade frame 18.

  On the other hand, with regard to the inclination of the sunshade frame 18, in the present embodiment, each connecting plate 25 corresponding to a different connecting position to the rotating shaft 20 in each area of the plurality of connecting plates 25 distributed sequentially to different areas of the rotating shaft 20. The offset amount is set, and the height position of the base end of the sunshade frame 18 for each area is aligned at the same height to create the same number of sunshade frame 18 inclinations as the number of areas. For example, in the present embodiment, the connection plate 25 supporting the base end portion on the inner peripheral side of each sunshade frame 18 is alternately distributed to the upper side or lower side region of the rotary shaft 20 and at different height positions. It is rotatably supported. Specifically, the connecting plate 25 connected to the odd numbered sunshade frame 18 of the eight sunshade frames 18 is sequentially fitted to the lower side 20 a of the rotary shaft 20 while the even numbered sunshade frame A connection plate 25 connected to the shaft 18 is sequentially fitted to the upper side 20 b of the rotary shaft 20. By this, when the sun protection frame 18 is stored, as shown in FIG. 8, on the base end side of the sun protection frame 18, for example, it is alternately arranged and distributed in two rows of the upper row and the lower row. At this time, the positions of the base end portions of the sunshade frame 18 are arranged in two upper and lower rows as shown in FIG. 9, but the positions connected to the rotary shaft 20 are different by one each. Adjustment of quantity is necessary. For example, when the connection plate 25 at the reference height is straight (offset amount 0), the remaining three connection plates 25 are bent in a crank shape, for example, one connection plate 25 faces upward. The other two connecting plates 25 are bent downward to be offset. Thereby, while the four connection plates 25 are spaced apart and fitted with the rotating shaft 20 by a fixed space | interval, the base end part of the sunshade frame 18 is arranged in the same height position. That is, in the case of this embodiment, each sunshade frame 18 is suspended by two types of inclination alternately.

  The connection plate 25 is fixed to, for example, the inner peripheral end side of the sunshade frame 18 via a clamp member 26. For example, as shown in FIG. 9, the clamp member 26 is composed of a pair of left and right sandwiching pieces 27 and a bolt 28 which connects them to adjust the interval, and the claws 27a at the lower end of the sandwiching piece 27 It is fixed by a bolt 28 in a state in which the neck 18 c is hooked and the head 18 a is held. The upper ends of the pair of sandwiching pieces 27 are bent inward toward each other to form upper claws 27 b, and a connection plate is formed between the upper surface of the head 18 a of the sunshade frame 18 and the upper claws 27 b of each sandwiching piece 27. It is provided so that the sunshade frame 18 and the connection plate 25 may be integrated by bolting in a state in which the concave portions on both sides of the connection plate 25 and the upper claws 27b are engaged with each other.

  Here, a through hole 35 for penetrating the rotary shaft 20 and the flanged bearing bush 32 is bored at the tip of the connecting plate 25, and the flanged bearing bush 32 also serving as a spacer between eight connecting plates 25. And the collar 33, the one rotation shaft 20 is inserted to be smoothly and rotatably connected. At both ends and an intermediate portion of the rotating shaft 20, retaining blocks 34 screwed and fixed to the rotating shaft 20 are disposed, respectively, and the central suspension columns 7 are maintained in a state where the height position of each connecting plate 25 is maintained. The rotary shaft 20 is fixed by penetrating the shaft hole (not shown) of the grooved bracket 17 fixed thereto.

  In the present embodiment, the outer peripheral end side of each sunshade frame 18 is suspended by the slide means 21 from the guide rail portion 3b of the annular girder frame 3 and supported so as to be movable circumferentially along the guide rail portion 3b. . Further, connection plates 25 having different bending depths (offset amounts) are fixed to the base end sides of the sunshade frames 18 via the clamp members 26, and the connection plates 25 are disposed on the upper side 20b and the lower side of the rotary shaft 20. As well as being distributed to the side 20a, each stage is also fitted in an axially shifted manner. Therefore, the sunshade frames 18 are arranged at the same height on the outer circumferential side, and alternately distributed in the vertical direction to the upper row and the lower row on the inner circumferential side (see FIG. 8). ). That is, the sunshade frames 18 have different inclination angles between the sunshade frames 18 adjacent to each other, and are distributed up and down so that they do not interfere with each other on the inner circumference side. Therefore, the sunshade sheet can be stored compactly. Moreover, the inclination angle of each sunshade frame 18 differs between the one distributed to the upper side and the one distributed to the lower side at the base end side, but in any case the sheet stretched between the sunshade frames 18 The inclination of the rod-like member 19 is set so that at least the radially inner side is lower than the outer side. As a result, instead of dropping rainwater dropped on the sun protection sheet 4 from the outer peripheral side of the sun protection sheet 4, it can be collected in the central rain water receiver 13 and then led to the ground through the vertical weir 15.

  Further, the tow rope 12 of the opening / closing operation means is connected to the leading sunshade frame 18 of each sunshade sheet 4 via the linking member 36. For example, as shown in FIGS. 10 and 11, the linking member 36 straddles the rope traveling guide pulley 41 above the girder frame 3 and the tow rope 12 routed between them, which is screwed to the roller support 23b. Thus, it consists of a substantially L-shaped plate material for arranging the rope fixing portion 37 for fixing the tow ropes 12 outside them, and provided so as to pass a position not interfering with the rope traveling guide pulley 41 during movement. . In the case of the present embodiment, the rope fixing portion is a fixing plate screwed to at least one of three screws arranged to maintain an equidistant-equal angle relationship (apex of a triangle) with each other. The tow rope 12 is passed between the three screws so as to be sewn, and is held down by a fixed plate. Thereby, the tow rope 12 is fixed in the pulling direction of the tow rope 12.

  On the other hand, the sunshade frames 18 other than the leading one are provided so as to be sequentially pulled out one by one by the sheet-like member 19 which is not connected with the tow rope 12 and is developed with the movement of the leading sunshade frame 18 There is. Further, the pulling direction by the tow rope 12 is pulled not only in the direction in which the sunshade frame 18 is pulled out from under the storage cover 11 but also in the direction in which it is pulled under the storage cover 11. Therefore, the awning frame 18 is sequentially pulled out while expanding the sheet-like member 19 with the movement of the leading sunshade frame 18, and sequentially stored while slacking the sheet-like member 19 with the retreat of the leading sunshade frame 18 when stored. While collecting the awning frame 18 that abuts, it is stored under the storage cover 11.

  The rearmost shading frame 18 in each section is fixed to the column 2 or the girder frame 3 by, for example, a locking unit (not shown). As a result, when the leading sunshade frame 18 is pulled out circumferentially by the tow rope 12, the sunshade frame 18 is pulled out and developed one after another by the sheet-like members 19 being tensioned, and the last tail sunk fixed The sheet-like member 19 is tensioned substantially horizontally with the frame 18.

  FIGS. 1 and 10 to 14 show an embodiment of the opening / closing operation means. The opening and closing operation means of the present embodiment is configured to simultaneously open and close the three sections of the sunshade sheet 4 using, for example, one tow rope 12. The tow rope 12 has an endless annular shape and is hung around a number of rope traveling guide pulleys 41 mounted on the girder frame 3 so as to be able to be operated by the awning user while being wound around one round A part is dropped along the optional post 2.

  A large number of rope traveling guide pulleys 41 are disposed on the upper surface of the girder frame 3 such that the tow rope 12 is drawn along the arc-shaped girder frame 3. For example, in the case of the present embodiment, eight rope traveling guide pulleys 41 are provided at intervals of 15 ° for each one of the girder frames 3 into which the girder frames 3 are divided into three, and thus traction is carried out. The ropes 12 are arranged so as to form a heptagon in each section, generally a 24-gon, and are configured to form a polygon approximate to a circle.

  Here, since the annular frame 1 is formed by joining three arc-shaped girder frames 3 with the three columns 2 interposed therebetween and forming an annular shape, the category in which the sunshade sheet 4 is opened and closed is divided by the columns 2 3 Limited to the area of each of the two compartments. Therefore, the tow rope 12 is provided so as to be detoured behind (inward in the radial direction) the column 2 and to be drawn around on the adjacent frame 3 at the intersection of the column frame 3 and the column 2. For example, by arranging the direction changing guide pulley 42 on the side surface of the beam frame 5, the tow rope 12 is routed from the rope traveling guide pulley 41 of the girder frame 3 through the direction changing guide pulley 42 of the side surface of the beam frame 5. Then, it passes between the rafter frame 6 and the beam frame 5 so as to go between the rafter frame 6 and the beam frame 5 and is drawn around the rope traveling guide pulley 41 on the adjacent girder frame 3.

  In this way, the tow rope 12 is drawn so as to go around in a range that fits within the width of the annular girder frame 3. That is, the tow rope 12 does not go out of the girder frame 3 when viewed from below. Moreover, since the tow rope 12 is stretched within a range that fits within the width of the annular girder frame 3 and is stretched by a polygon that approximates a circle, the sunshade frame 18 is placed against the sunshade frame 18 regardless of the position of the sunshade frame 18 Thus, traction can be applied substantially tangentially. For this reason, it is possible to draw around the sunshade frame 18 without applying unnecessary force. Of course, the number and arrangement position of the above-mentioned rope traveling guide pulleys 41 are not particularly limited, and an appropriate number of rope traveling guide pulleys 41 and the like are appropriately arranged as needed. .

  Furthermore, a portion of the tow rope 12 is suspended along the post 2 so that it can be manipulated at the awning user's hand. For example, a direction changing guide pulley 42 for guiding the tow rope 12 in the horizontal direction from the top of the girder frame 3 to the beam frame 5 and a vertical guide pulley 43 for guiding the tow rope 12 in the vertical direction , And a portion of the tow rope 12 is drawn down along the support 2. And, at the part of the column 2 where the tow rope 12 is hanging down, the rope fixing device 44 and the pretensioner 45 for taking the slack of the rope are provided, and the tow rope 12 is fixed at any position. Tension is always applied to prevent slack.

  As the rope fixing device 44, for example, a rope stop called a crumb cleat is used. The crumb cleat has, for example, a V-shaped (楔 -shaped) groove formed between two opposing walls and one or more return ridges (in other words, return ridges) for increasing friction on both slopes The groove is formed to intersect with the moving direction of the rope, and the tow rope 12 is fitted in the hook-like groove to fix the movement of the tow rope 12 by friction. Since the gutter-like groove narrows toward the groove bottom, if the crumb cleat is installed so that the position where the tow rope 12 to be suspended is pulled straight is near the bottom of the groove, the tow rope 12 The more tension you get into the grooves, the easier it is to stop. That is, simply pulling the tow rope 12 lightly in the groove holds the tow rope 12 firmly, and the tow rope 12 can be easily fixed.

  This crumb cleat applies a restraining force only in one direction, and for example, in a state of being installed so as to fix the tow rope 12 moving upward as shown in FIG. Only the rope moving to can be fixed, and the rope is released downward (in the direction of the arrow A) to release the fixation. Therefore, when opening and closing the sunshade, it is performed by simply pulling the tow rope 12 downward or by pulling the rope out of the groove of the crumb cleat and moving it in any direction. And when it is desired to fix the shade at an arbitrary position, it is fixed simply by pushing the tow rope 12 lightly into the groove of the crumb cleat. Thus, the sun protection sheet 4 can be fixed at the stored state and the expanded state as well as at any position and angle therebetween.

  On the other hand, the pretensioning device 45 eliminates the slack of the tow rope 12 by constantly applying tension to the tow rope 12 so that the tow rope 12 being pulled around by the rope traveling guide pulley 41 or the like falls off. For preventing the sun protection sheet 4 from rattling in the circumferential direction, for example, a pulley on which the traction rope 12 is wound and a tension spring 47 interposed between the pulley and the column 2 , And is provided so that the pulley 46 is always pulled by the tension spring 47. Reference numeral 48 in the figure is a hook fixed to the support 2.

  According to the opening and closing operation means configured as described above, when expanding the sunshade sheet 4 in the stored state shown in FIG. 15A and FIG. 2, the index rope 12 is operated in the direction A shown in FIG. Thus, the tow rope 12 can be generally rotated forward (counterclockwise in FIG. 1). Moreover, since the tow rope 12 is drawn along the outline of the girder frame 3, a pulling force can be exerted on the sunshade frame 18 in a substantially tangential direction. That is, a pulling force can be applied in a direction (tangent direction) orthogonal to the sunshade frame 18. Therefore, the degree of application of the tractive force becomes constant and the operability is good, and all the tractive force can be applied without loss with respect to the opening and closing operation of the sunshade frame 18.

  Moreover, since the inner circumferential end of the sunshade frame 18 is supported on the rotary shaft 20 and the outer circumferential side is supported by the slide means 21, the operating force for opening and closing can be reduced. Therefore, only by operating one tow rope 12, the three sunshade sheets 4 can be easily opened and closed simultaneously with a light operating force. Moreover, since the tow rope 12 is drawn along the contour of the girder frame 3 by the rope traveling guide pulley 41 disposed on the upper surface of the girder frame 3, it can be drawn so as not to be seen from below.

  In addition, when the tow rope 12 moves forward and the leading sunshade frame 18 is pulled forward, the respective subsequent sunshade frames 18 are also connected to each other by the sheet-like members 19, so that they follow the leading sunshade frame 18. The other sunshade frames 18 are also sequentially pulled out, and the sunshade sheet 4 is developed. And since the last sunshade frame 18 is fixed to the pillar 2 or the digit frame 3, when the leading sunshade frame 18 reaches the front pillar 2, each sheet shape between all sunshade frames 18 The member 19 is in a tensioned state and is maintained in a substantially horizontal state without slack. Here, "stretching the sheet-like member 19 in a substantially horizontal state" includes, of course, the case where the sheet-like member 19 is stretched with a pin so that the sheet-like member 19 is horizontal without slack. Also included.

  Further, when the sunshade sheet 4 in the unfolded state shown in FIG. 15 (B) and FIG. 1 is stored, the tow rope 12 is moved backward by operating the tow rope 12 in the B direction shown in FIG. In the clockwise direction). As a result, the leading sunshade frame 18 connected to the tow rope 12 moves in the backward direction and moves until it abuts on the trailing sunshade frame 18 while abutting and pushing back the trailing sunshade frames 18 one after another until it abuts on the trailing sunshade frame 18 fixed. . At this time, the sheet-like members 19 between the sunshade frames 18 are dropped and folded. As a result, the sun protection sheet 4 is put under the storage cover 11 and stored.

  In general, in the case of awning for outdoor use, the sunshade frame 18 for suspending the sheet-like member 19 needs to have a cross-sectional shape with a height to increase bending strength and to increase the second moment of area. For this reason, when the base end of the sunshade frame 18 is connected by one rotation shaft 20 and it is attempted to open and close in a fan shape, interference between sunshade frames 18 occurs at a portion approaching the key portion of the fan. There is a problem that the angle of the fan can not be narrowed as described above. That is, when the sun protection sheet 4 is stored, if the sun protection frames 18 interfere with each other on the inner peripheral end side, the space between the adjacent sun protection frames 18 opens on the outer peripheral end side. There is. However, since the sunshade sheets 4 of the present embodiment are alternately arranged at the inclination angle of the sunshade frame 18 so that they do not interfere with each other in the vicinity of the rotation shaft 20 which is important, It can be folded and stored compactly.

  Incidentally, the sunshade sheet 4 can freely change the opening degree from the stored state to the deployed state or vice versa by the operation of the tow rope 12 and fixes the tow rope 12 to the support 2 Can be fixed at any position and at any opening degree.

  According to the above-described embodiment, it is possible to provide the awning of the novel novel movement of opening and closing the sun protection sheet 4 in the horizontal plane along the annular frame 1. In addition, it is possible to realize an interesting movement of simultaneously opening and closing in a plurality of sections and simultaneously opening and closing the sun protection sheet 4 in each section, so that awning which does not take time for expansion and storage (fully open fully closed) can be provided.

  The above-described embodiment is an example of the preferred embodiment of the present invention, but is not limited to this, and various modifications can be made without departing from the scope of the present invention.

  For example, in the above-described embodiment, the sunshade frame 18 is configured to be alternately distributed to the upper and lower two rows on the base end (root) side, but this is not a limitation. It may be distributed to columns or three or more columns. That is, by dividing the position of the plate fitted to the rotary shaft 20 into three or more places and sequentially distributing them, it is possible to further suppress the interference on the base end side of the sunshade frame 18. That is, the end portion on the inner circumferential side is rotatably connected so as to be sequentially distributed and stacked at different height positions of the rotary shaft 20 disposed at the center of curvature of the girder frame 3 via the connection plate 25, a sunshade frame The inclination angles of 18 are different from each other, and it may be distributed in the vertical direction so that they do not interfere with each other in the vicinity of the rotation shaft 20 which is the key.

  Moreover, in the above-mentioned embodiment, when it expands, the sheet | seat-like member 19 is provided so that the sheet-like member 19 may be tensioned and it may be horizontally tensioned, but it is not specifically limited to this. The member 19 may be deployed with slack. For example, as shown in FIG. 16, by directly connecting adjacent sun protection frames 18 with a tape-like connection member 49 shorter than the width of the sheet-like member 19, the next sun protection frame before the sheet-like members 19 stretch. As a structure from which 18 is pulled out, you may make it the sun protection frame 18 comrades which adjoin with the tape-shaped connection member 49 be pulled and expand | deployed. In this case, the distance between the adjacent sunshade frame 18 and the sunshade frame 18 is maintained at a constant interval by stretching the tape-like connecting members 49 before the sheet-like members 19 are stretched. The sheet-like member 19 can form a graceful drop with drooping between them.

  Moreover, in the above-mentioned embodiment, although it is set as the support structure which suspends the sunshade frame 18 under the cyclic | annular girder frame 3 by the slide means 21, it is not specifically limited to this, Guide rail of the girder frame 3 depending on the case The front end of the sunshade frame 18 may be housed and slidably supported inside the portion 3 b, or the front end portion of the sunshade frame 18 may be mounted on and supported by the girder frame 3.

  Moreover, in the above-mentioned embodiment, although three circular-arc-shaped girder frames 3 are joined on both sides of the support 2 to form a non-perfect circular annular shape having three curvature centers, it is not particularly limited thereto. For example, by supporting the annular girder frame 3 consisting of one perfect circle so as to be supported by the support 2, the movement range of the sunshade frame 18 may be approximately one revolution. That is, the circular awning may be configured by one awning sheet 4 that opens and closes so that the leading sunshade frame 18 rotates approximately one turn around one rotation axis 20. Also, even when combining a plurality of digit frames 3 and a fan-shaped sunshade sheet 4, it is not limited to the combination of three sunshade sheets 4 etc., but two arcs may be joined together or two sections may be connected. One circular awning may be configured as a whole as four or more sections obtained by connecting the above-described arcs. Furthermore, although the above-mentioned embodiment mainly demonstrated the case where the circular awning was comprised as a whole, combining several digit flame | frame 3 and the fan-shaped sunshade sheet 4, it is not specifically limited to this, 1 A fan-shaped unit consisting of a set of frame units and a sun protection sheet, for example, it can be configured as an awning of one section (angle 120 °) of the above-mentioned embodiment, or a plurality of units combined to form a semicircle or It may be configured as a fan-shaped awning of less than °°. In addition, the angle of one section of the sector formed by one set of frame unit and the sunshade sheet is not particularly limited to about 120 ° as illustrated, but may be a larger angle or a small angle such as 90 °, Furthermore, it may be formed at an arbitrary angle of 60 ° or smaller.

  Furthermore, in the above-mentioned embodiment, although it is set as the operation mechanism which opens and closes three sections of sunshade sheets 4 simultaneously with one tow rope 12, it is not restricted in particular in particular, and in some cases, every sunshade sheet 4 of each section Alternatively, the sun protection sheet 4 may be opened and closed independently for each section by providing an operation mechanism.

  In the above-described embodiment, the connection plate 25 at the base end of the sunshade frame 18 is alternately distributed to the upper side 20b and the lower side 20a of the rotary shaft 20 while being fitted at different heights and connected. By making the bending depth of the connection plate 25 of the sunshade frame 18 different for each sheet, the base end side of the sunshade frame 18 is arranged in two horizontal rows of the upper stage and the lower stage. It is not limited, for example, by making each connection plate 25 into a straight plate without bending, the arrangement of the plurality of sunshade frames 18 distributed in the upper and lower two rows is linked to the height position connected to the rotation shaft 20 It may be arranged in an oblique line that increases by one step. Even in this case, since interference of the sunshade frame 18 near the rotation axis 20 of the sunshade sheet 4 can be eliminated and the sunshade frames 18 adjacent on the outer peripheral end can be closed until they contact each other. The width can be closed in triangles and sectors to a minimum. Therefore, the difference in the opening degree between the unfolded and unfolded state of the sun protection sheet 4 can be further widened than before.

  Further, in the above-described embodiment, the dimensions of the sheet-like members 19, in particular, the horizontal width (length in the circumferential direction) are the same, and the intervals of the sunshade frames 18 when the sunshade sheet 4 is opened are the same. However, the present invention is not particularly limited to this, and in some cases, they may have different lengths. Of course, with regard to the length in the radial direction, it is preferable to make the length of the sheet-like member 19 equal to the length closing the gap between the girder frame 3 and the rainwater receiver 13 so as not to impair the function as a sunshade. Needless to say.
