Description

Application of Article 30, Paragraph 2 of the Patent Act On June 9, 2017, the applicant Takano Co., Ltd. was released at the Takano Co., Ltd. exhibition hall held at the exhibition hall Ruby Village (14-353 Akaho, Komagane City, Nagano Prefecture).

The present invention relates to a self-supporting awning. More specifically, the present invention relates to a self-supporting awning that forms a ceiling that can be opened and closed by moving the awning sheet in a horizontal plane.

As a so-called self-supporting awning that is used independently in a situation where it is separated from the building frame, it has a rectangular shape composed of columns arranged at four corners and four girder frames supported on it. A pergola-type awning that opens and closes by sliding a awning sheet stretched on a roof frame unit in the longitudinal direction thereof is known (Patent Document 1).

This pergola-type awning roof frame unit is equipped with girder frames on the front, back, left and right, and the four corners are supported by columns. A plurality of hanging pipes are hung between the left and right girder frames, and a canvas is stretched between the hanging pipes. That is, a plurality of small canvases are connected by a hanging pipe to form one large awning sheet. Of each suspension pipe, the suspension pipe on the rear girder frame side (hereinafter referred to as fixed suspension pipe) is fixed to the left and right girder frames, and suspension pipes other than the fixed suspension pipe are left and right via sliders (not shown). It is possible to move to the digit frame of. Then, by moving the hanging pipe at the head (on the front girder frame side) back and forth by the rope driving means, the other hanging pipes connected can also be moved, and the awning sheet can be opened and closed as a whole.

Japanese Unexamined Patent Publication No. 2014-169563

However, since the opening and closing mechanism is such that the rectangular awning sheet moves linearly in parallel while being folded from the end inside the rectangular roof frame unit, the movement of the awning sheet lacks novelty and fun, and the left and right sides of the hanging pipe are not. If the movements of the sliders at both ends cannot be synchronized, it will be difficult to open and close easily with a light operation force.

An object of the present invention is to provide a self-supporting awning that can easily open and close the awning sheet with a light operating force.

In order to achieve such an object, the self-supporting awning according to claim 1 is between a frame unit having a girder frame having an arc-shaped or annular guide rail portion, and a plurality of awning frames as a frame and the awning frame. It is composed of a triangular sheet-like member stretched on the awning frame, and by bundling the ends on the base end side of the awning frame and rotatably connecting them with one essential rotating shaft, a fan shape is formed around the rotating shaft. The awning sheet that opens and closes and the tow rope that runs along the girder frame across multiple guide pulleys mounted on the upper surface of the girder frame are connected to the awning frame and linked with the movement of the tow rope to connect the awning sheet. Equipped with an opening / closing operation means for opening and closing, the tow rope is stretched within the width of the girder frame, and the traction force is applied to the awning frame in the tangential direction regardless of the position of the awning frame. Therefore, the outer peripheral end of the awning sheet is slidably suspended in the circumferential direction along the guide rail portion of the girder frame via the sliding means, and the inner peripheral end is suspended via the connecting plate. The rotation axes placed at the center of curvature of the girder frame are sequentially distributed to different height positions and rotatably connected so that they can be stacked. It is arranged in the vertical direction so that it does not interfere with each other .

Further, in the self-supporting awning according to the invention of claim 2, the girder frame is divided into a plurality of sections, the rotation axis of the awning sheet is arranged at the center of curvature of the girder frame in each section, and the awning sheet is provided for each section. In addition, the tow rope to which the awning frame of each awning sheet is connected is composed of one endless annular rope, and the awning sheet of each section is opened and closed at the same time.

Further, the self-supporting awning according to the third aspect of the present invention is characterized in that the tow rope of the opening / closing operation means is laid around in a part thereof so as to hang down along any of the columns of the frame unit. And.

Further, the self-supporting awning according to the fourth aspect of the present invention is provided with a pre-tensioning device for removing the slack of the tow rope, and is characterized in that tension is constantly applied so as not to cause the slack in the tow rope.

According to the self-supporting awning according to claim 1 , adjacent awning frames are distributed in the vertical direction near the rotation axis, which is the key to the fan-shaped awning sheet, so that they do not interfere with each other. It can be stored compactly without leaving a space between the frames, and does not take up space when stored. Moreover, since the tow rope is stretched within the range within the width of the annular girder frame, the traction force can be applied to the awning frame in the tangential direction regardless of the position of the awning frame. Therefore, the degree of application of the traction force is constant and the operability is good, and all of the traction force can be applied without waste in the opening / closing operation of the awning frame. Therefore, the awning sheet can be easily opened and closed with a light operating force.

Moreover, since the tow rope is routed within the width of the girder frame, it can be routed so that it cannot be seen from below. In addition, it is possible to provide an awning with a novel movement that has never been seen before, in which the awning sheet opens and closes in a fan shape in a horizontal plane along an annular frame centered on the axis of rotation.

Further, according to the self-supporting awning according to claim 2, it is possible to realize an interesting movement in which a plurality of awning sheets are opened and closed at the same time in a plurality of sections, and the awning sheets are opened and closed at the same time in each section. It does not take time to (fully open) or store (fully closed). Moreover, at the time of deployment, a plurality of awnings arranged in a ring shape can form one large circular awning as a whole.

Further, according to the self-supporting awning according to claim 3, since a part of the tow rope of the opening / closing operation means is drawn so as to hang down along the support column, the opening / closing operation can be easily performed.

Further, according to the self-supporting awning according to claim 4, since tension is constantly applied to the tow rope by the pre-tensioning device, the tow rope is prevented from loosening and falling off from the guide pulley, and is shaded. It is possible to prevent the sheet from rattling in the circumferential direction.

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

1 to 15 show an example of an embodiment of the self-supporting awning of the present invention. In the present embodiment, the direction in which the awning sheet 4 is expanded (expanded) is the front direction, the direction in which the awning sheet 4 is retracted (closed) is the rear direction, the radial outer side is the outer peripheral side, and the radial inner side is the inner peripheral side or the base end side. Call.

As shown in FIGS. 1 and 2, the self-supporting awning according to the present embodiment forms a ceiling that can be opened and closed by swirling the awning sheet 4 along the annular frame 1 so as to spread a fan in a horizontal plane. A fan-shaped awning sheet 4 is provided for each fan-shaped section between the columns 2, and a tow rope 12 of an opening / closing operation means connected to a awning frame 18 at the head of the awning sheet 4 for each section is operated. As a result, the three compartments of the awning sheet 4 are configured to be opened and closed at the same time. That is, in the awning of the present embodiment, three fan-shaped awning sheets 4 are arranged in a ring shape to form an awning (awning) as a whole, and the fan-shaped awning sheet 4 for each section is provided by one opening / closing operation means. Is a structure that opens and closes at the same time.

As shown in FIG. 7, for example, the annular frame 1 includes an arcuate girder frame 3, a strut 2 that supports both ends of the girder frame 3, and a strut arranged in the center (hereinafter, referred to as a central suspension strut 7). A horizontal structural material (hereinafter referred to as a beam frame 5) and an oblique structural material (hereinafter referred to as a beam frame 5) arranged radially around the central suspension column 7 and connecting the central suspension column 7 and the peripheral columns 2 in the radial direction. , Called a rafter frame 6). In the case of the present embodiment, an annular frame 1 is formed by connecting three fan-shaped sections partitioned by three girder frames 3 and three columns 2 supporting both ends thereof in the circumferential direction, and each fan-shaped section is formed. A foldable awning sheet 4 can be opened and closed. The girder frame 3 of each sector has an arc shape, but the girder frame 3 of each sector has an arc shape with the rotation axis 20 provided for each fan section as the center of curvature, and is the center of the entire annular frame 1. The radius of curvature is different from that of a circle whose center of curvature is the center of the central suspension column 7. That is, instead of forming a perfect circular ring having one center of curvature, a non-round circular ring having three centers of curvature connected by connecting three arcs is formed.

For example, the support column 2 is composed of a square pipe having a substantially square cross-sectional shape, and the girder frame 3 is connected to two opposite surfaces in the circumferential direction, that is, side surfaces, while the inner surface (diameter inner side) orthogonal to them. The beam frame 5 is connected to the beam frame 5. For example, as shown in FIG. 7, a U-shaped or square tubular bracket 8 fitted to the girder frame 3, the beam frame 5, and the rafter frame 6 is previously fixed to the support column 2 and the central suspension support column 7, and the bracket 8 is used. Is fixed by bolting in a state where it is fitted to the end opening of each frame. Further, the support column 2 and the girder frame 3 are connected to each other and reinforced by, for example, a triangular reinforcing plate (triangular bracket 9) addressed to the joint surface portion. Further, between the support column 2 and the beam frame 5, for example, a triangular reinforcing plate (triangular bracket 10) is addressed to the joint surface portion to be connected to each other and reinforced. As a result, the column 2, the girder frame 3, the beam frame 5, and the rafter frame 6 are fixed (rigidly joined) to each other, and the central suspension column 7 is supported to form a rigid frame structure.

At the position where the awning sheet 4 of each section is folded and gathered together, a storage cover 11 is provided to prevent the awning sheet 4 in the stored state from getting wet with rain, getting sunburned, or getting dirty with dust (FIG. 1). And see Figure 2). The storage cover 11 is fixed to the beam frame 5 and the girder frame 3 in a state of being raised via a spacer (not shown) so as to straddle the girder frame 3 and the beam frame 5. It is provided so as to form a gap through which the tow rope 12 passes between the five and the tow rope 12. The storage cover 11 forms, for example, a substantially triangular shape, covers the awning frame 18 at the head of the awning sheet 4 in the adjacent section where the awning sheet 4 in the stored state is accommodated, and the inner peripheral edge thereof is the rainwater receiver 13. It is said to be large enough to reach the inside of. As a result, the sunshade sheet 4 to be stored is covered and protected, and when the sunshade sheet 4 is unfolded, a gap is not generated between the sunshade sheet 4 and the beam frame 5, so that the annular frame 1 has an annular frame 1. Care is taken to prevent raindrops from leaking inside.

As shown in (C) of FIG. 7, for example, the central suspension column 7 has an irregular hexagonal cross-sectional shape in which wide surfaces and narrow surfaces are alternately formed, and has three locations. The rafter frame 6 and the beam frame 5 are rigidly joined to each of the relatively large planes via the brackets 8, and the three relatively small planes between them are the key points of the awning sheet 4 that opens and closes in a fan shape. A bracket 17 for bearing the rotating shaft 20 is attached. The bracket 17 has, for example, a U shape having an upper side and a lower side, and a rotation shaft 20 of the awning sheet 4 is supported between the upper side and the lower side.

A shallow funnel-shaped rainwater receiver 13 is suspended from the central suspension column 7 (see, for example, FIGS. 6 and 9). At the center of the rainwater receiver 13, a water collector 40 through which the horizontal trough 14 is penetrated is provided so as to collect rainwater collected in the rainwater receiver 13 and pour it into the horizontal trough 14. A horizontal gutter 14 is connected to the water collector 40 with a predetermined inclination, and is further connected to a vertical gutter 15 attached to the inside of an arbitrary support column 2, and rainwater that has fallen on the awning sheet 4 and the roof 16. Is provided so as to collect water in a rainwater receiver 13 and then guide water to the ground via a horizontal gutter 14 and a vertical gutter 15. This prevents rainwater from flowing down from the periphery of the awning like a waterfall when it rains heavily, enabling continuous awning installation. In the case of the present embodiment, the rainwater receiver 13 is suspended by being connected to a bracket 17 bearing the rotating shaft 20 with a hanger 40a, but the support structure is not particularly limited to this, for example, central suspension. It may be provided so as to be directly suspended via the hanger 40a on any surface of the hexagonal planes of the columns 7, for example, three surfaces arranged at equal intervals.

Further, a conical roof 16 is placed on the top of the central suspension column 7. The roof 16 has a size slightly protruding outward in the radial direction from the inner peripheral edge of the sheet-shaped member 19 of the awning sheet 4, and is arranged so as to cover the inner peripheral edge side of the awning sheet 4 and the storage cover 11. .. As a result, the rainwater received by the roof 16 is dropped to a position closer to the inner peripheral edge side of the sunshade sheet 4 or the storage cover 11, and is further discharged to the rainwater receiver 13.

In the case of the present embodiment, the girder frame 3 has at least a guide rail portion 3b that holds and supports the slide means 21 on the outer peripheral end side of the awning frame 18 so as to be movable in the circumferential direction, for example, as a structure. A square pipe 3a having a rectangular length that guarantees the strength of the rail and a channel material constituting the guide rail portion 3b are joined back to back. FIG. 11 shows an example of the cross section of the girder frame 3. The channel material / guide rail portion 3b is arranged and welded inward in the radial direction of the square pipe portion 3a so that the opening faces the central suspension column 7. In the case of the present embodiment, a recess 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 recess so as to be integrated in the vertical direction. Has been done. In the present embodiment, the girder frame 3 is configured by combining the channel material 3b and the square pipe 3a, but the present invention is not particularly limited to this, and the guide rail portion 3b is an extruded material integrally molded in advance. It may be configured.

As shown in FIG. 1, a hanging wire 29 is stretched between the central portion of the arc-shaped girder frame 3 and the central suspension column 7 so that the central portion of the girder frame 3 does not bend. .. One end of the suspension wire 29, for example, the radial outer end, is fixed to the bracket 30 screwed to the outer peripheral surface side of the girder frame 3, while the other end, that is, the radial inner end is the central suspension column 7. It is hooked on the hook 31. Then, an appropriate tension is applied with a turnbuckle (not shown).

In the case of the present embodiment, the support column 2 is provided so as to be directly buried and fixed in the ground, but the present invention is not particularly limited to this, and for example, a substrate (not shown) is attached to the bottom of the support column 2. It is fixed by welding or bolting, and the board is bolted to a structure or foundation, or a cylindrical block that becomes a weight, such as a block that can be split in half, is placed on the board. It may be used by fixing it by weight.

The awning sheet 4 is composed of, for example, a plurality of awning frames 18 as a framework and a triangular sheet-shaped member 19 stretched between the awning frames 18, and is an end portion of the awning frame 18 on the base end side. Is provided in a fan shape that opens and closes around the rotating shaft 20 by bundling them and rotatably connecting them with one main rotating shaft 20. The awning sheet 4 of the present embodiment is provided so as to have substantially the same size as the fan-shaped section formed between one annular girder frame 3 and the beam frame 5 in the unfolded state, and is provided on the central suspension column 7. On the other hand, the rotation shaft 20 is arranged in parallel (that is, in the vertical direction) so as to be openable and closable in a horizontal plane.

As shown in FIGS. 8 and 10, the awning frame 18 has a head portion 18a for hanging and a main body portion 18b for connecting the sheet-shaped member 19, and is a boundary between the head portion 18a and the main body portion 18b. A groove (referred to as a neck 18c) into which the clamp member 22 and the claw portion of the clamp member 26 are inserted is formed in the portion in the longitudinal direction. In the case of the present embodiment, two long grooves 18c for fitting the sheet-shaped member 19 are provided in parallel on the bottom surface of the main body portion 18b. The cross-sectional shape of each elongated groove 18c is circular, and the opening portion on the bottom surface is narrowly formed. The awning frame 18 having such a cross-sectional shape is formed by, for example, extrusion molding of aluminum. Therefore, in the awning frame 18 and the sheet-shaped member 19, the tubular end portion 19a of the sheet-shaped member 19 is charged into the long groove 18c together with the core material 19b from the end opening, and the sheet-shaped member 19 is inserted from the opening portion on the bottom surface. It is fixed by pulling it out. Further, by charging and fixing one end of each of the front and rear awning sheets 4 into the two long grooves 18b, the front and rear awning frames 18 are connected by the sheet-like member 19 stretched between them. As the sheet-shaped member 19, for example, a canvas or the like can be used, but the sheet-like member 19 is not limited to this. Further, although not shown, the openings at both ends of the awning frame 18 are closed by, for example, a cap (not shown).

In the awning sheet 4 configured as described above, the end portion on the outer peripheral side is hooked on the guide rail portion 3b of the girder frame 3 via the sliding means 21 and is slidably suspended in the circumferential direction, and the inner circumference thereof. Different height positions of the rotating shaft 20 whose side ends are arranged at the center of curvature of the girder frame 3 via the connecting plate 25 For example, an upper region (referred to as an upper side 20b) and a lower region (lower side 20a). It is rotatably connected so as to be alternately distributed and stacked, and has a structure that opens and closes in a fan shape along the girder frame 3 with the rotation shaft 20 as a key (see FIGS. 9 and 15).

As shown in FIG. 10, for example, the slide means 21 includes a clamp member 22 for attaching to the awning frame 18, a slider 23 suspended from a guide rail portion 3b of the girder frame 3 and movable in the circumferential direction, and a clamp member. It is composed of a fastening bolt 24 as a fastener for connecting the 22 and the slider 23. The clamp member 22 connects, for example, a pair of left and right holding pieces 22a that hold the head (square pipe portion) 18a of the awning frame 18 and a pair of holding pieces 22a that sandwich the head 18a to hold the head 18a. The lower claw portion 22c, which is composed of the tightening bolt 22b and is bent inside the lower end of the holding piece 22a, is hooked on the neck portion 18c of the awning frame 18, and the upper claw portion 22d folded back to the outside of the upper end is the slider 23. It is fastened to and fixed to the slider 23 by the fastening bolt 24 in a state of being engaged with the base portion 23c of the above. The holding piece 22a is provided so that the upper claw portion 22d is passed through the slit 23d formed in the base portion 23c of the slider 23 and hooked on the base portion 23c so as to be adjustable and movable within the width of the slit 23d. This is provided so that the clearance can be adjusted when the pair of holding pieces 22a is inserted from the end portion of the head 18c.

The slider 23 is composed of a roller 23a that can roll along the guide rail portion 3b of the girder frame 3 and a roller support 23b that supports the roller 23a. Here, if at least one roller is present, the tip of the awning frame 18 can be rolled while being hooked on the guide rail portion 3b of the annular girder frame 3, but preferably a plurality, more preferably only in the moving direction. Instead, the structure is such that a plurality of rollers are arranged in the vertical direction as well. For example, in the case of the present embodiment, there are four rollers, two rollers that roll when they come into contact with the ceiling surface of the guide rail portion 3b, and two rollers that roll when they come into contact with the bottom surface of the guide rail portion 3b at all times. A number of rollers are adopted, and they are arranged so as to be separated from each other in the moving direction, and are provided so as to stabilize the posture of the awning frame 18.

On the other hand, regarding the inclination of the awning frame 18, in the present embodiment, for each connecting plate 25 corresponding to a different connecting position with respect to the rotating shaft 20 in each region of the plurality of connecting plates 25 sequentially distributed to different regions of the rotating shaft 20. The offset amount is set so that the height positions of the base ends of the awning frames 18 for each region are arranged at the same height to create the inclination of the awning frames 18 as many as the number of regions. For example, in the present embodiment, the connecting plate 25 that supports the base end portion on the inner peripheral side of each awning frame 18 is alternately distributed to the upper or lower region of the rotating shaft 20 and at different height positions. It is rotatably supported. Specifically, the connecting plate 25 connected to the odd-numbered awning frame 18 of the eight awning frames 18 is sequentially fitted to the lower side 20a of the rotating shaft 20, while the even-numbered awning frame is fitted in sequence. The connecting plate 25 connected to 18 is sequentially fitted to the upper side 20b of the rotating shaft 20. As a result, when the awning frame 18 is stored, as shown in FIG. 8, on the base end side of the awning frame 18, for example, the awning frame 18 is alternately arranged and distributed in two rows, an upper row and a lower row. At this time, the positions of the base ends of the awning frame 18 are arranged in two upper and lower rows as shown in FIG. 9, but the positions connected to the rotating shaft 20 are different by one, so that the offset of the connecting plate 25 is offset. The amount needs to be adjusted. For example, when the reference height connecting plate 25 is straight (offset amount 0), the remaining three connecting plates 25 are bent in a crank shape, for example, one connecting plate 25 faces upward. It is bent to offset, and the other two connecting plates 25 are bent to offset downward. As a result, the four connecting plates 25 are fitted to the rotating shaft 20 at regular intervals, while the base ends of the awning frame 18 are arranged at the same height position. That is, in the case of the present embodiment, the awning frames 18 are alternately suspended with two types of inclinations.

The connecting plate 25 is fixed to, for example, the inner peripheral end side of the awning frame 18 via a clamp member 26. As shown in FIG. 9, for example, the clamp member 26 is composed of a pair of left and right holding pieces 27 and a bolt 28 that connects them to adjust the distance, and the claw portion 27a at the lower end of the holding piece 27 is a shade frame 18. The neck portion 18c is hooked and the head portion 18a is sandwiched and fixed by the bolt 28. The upper ends of the pair of holding pieces 27 are bent inward to form the upper claw portion 27b, and a connecting plate is formed between the upper surface of the head 18a of the awning frame 18 and the upper claw portion 27b of each holding piece 27. The sunshade frame 18 and the connecting plate 25 are integrated by tightening bolts in a state where the recesses on both side surfaces of the connecting plate 25 and the upper claw portion 27b are engaged with the 25 installed.

Here, a through hole 35 for penetrating the rotating shaft 20 and the bearing bush 32 with a flange is drilled at the tip of the connecting plate 25, and the bearing bush 32 with a flange that also serves as a spacer is formed between the eight connecting plates 25. One rotation shaft 20 is inserted and smoothly rotatably connected to each other while interposing the collar 33 and the collar 33. Retaining blocks 34, which are screwed to and fixed to the rotating shaft 20, are arranged at both ends and the middle portion of the rotating shaft 20, respectively, and are attached to the central suspension column 7 in a state where the height position of each connecting plate 25 is maintained. The rotary shaft 20 is passed through the shaft hole (not shown) of the groove-shaped bracket 17 to be fixed and fixed.

In the present embodiment, the outer peripheral end side of each awning frame 18 is suspended from the guide rail portion 3b of the annular girder frame 3 by the sliding means 21 and supported so as to be movable in the circumferential direction along the guide rail portion 3b. .. Further, a connecting plate 25 having a different bending depth (offset amount) is fixed to the base end side of each awning frame 18 via a clamp member 26, and each connecting plate 25 is fixed to the upper side 20b and the lower stage of the rotating shaft 20. It is distributed to the side 20a and is fitted so as to be offset in the axial direction in each stage. Therefore, the awning frames 18 are arranged at the same height on the outer peripheral side, and are alternately arranged in the upper row and the lower row on the inner peripheral side in the vertical direction (see FIG. 8). ). That is, the awning frames 18 have different inclination angles between the adjacent awning frames 18, and are distributed vertically so as not to interfere with each other on the inner peripheral side. Therefore, the awning sheet can be stored compactly. Moreover, the inclination of each awning frame 18 differs between the one distributed to the upper side and the one distributed to the lower side on the base end side, but in any case, the sheet stretched between the awning frames 18. The shape member 19 is provided so that the inclination of the shape member 19 is at least on the inner side in the radial direction as compared with the outer side. As a result, the rainwater that has fallen on the awning sheet 4 can be collected in the central rainwater receiver 13 and then guided to the ground through the downspout 15 instead of being dropped from the outer peripheral side of the awning sheet 4.

Further, a tow rope 12 for opening / closing operation means is connected to the awning frame 18 at the head of each awning sheet 4 via a connecting member 36. As shown in FIGS. 10 and 11, for example, the connecting 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. It is made of a substantially L-shaped plate material in which a rope fixing portion 37 for fixing the tow rope 12 is arranged outside them, and is provided so as to pass through a position that does not interfere with the rope traveling guide pulley 41 during movement. .. In the case of this embodiment, the rope fixing portion consists of three screws arranged so as to maintain an equidistant and equiangular relationship (the vertices of a triangle) with each other, and a fixing plate screwed to at least one of them. The tow rope 12 is passed through between the three screws so as to be sewn, and is pressed by a fixing plate. As a result, the tow rope 12 is fixed in the pulling direction of the tow rope 12.

On the other hand, the awning frame 18 other than the leading awning frame 18 is not connected to the tow rope 12, and is provided so as to be sequentially pulled out one by one by the sheet-shaped member 19 developed with the movement of the leading awning frame 18. There is. Further, the pulling direction by the tow rope 12 is pulled not only in the direction in which the awning frame 18 is pulled out from under the storage cover 11, but also in the direction in which the awning frame 18 is pulled under the storage cover 11. Therefore, the awning frame 18 is sequentially pulled out while expanding the sheet-shaped member 19 as the leading awning frame 18 moves, and sequentially while loosening the sheet-shaped member 19 as the leading awning frame 18 retracts during storage. The awning frames 18 that have come into contact with each other are collected and stored under the storage cover 11.

The rearmost awning frame 18 in each section is fixed to the support column 2 or the girder frame 3 by, for example, a locking means (not shown). As a result, when the leading awning frame 18 is pulled out in the circumferential direction by the tow rope 12, the awning frame 18 is pulled out and deployed one after another by the sheet-like member 19 being tense, and the fixed last awning frame 18 is pulled out. The sheet-like member 19 is stretched substantially horizontally with the frame 18.

1 and 10 to 14 show an embodiment of the opening / closing operation means. The opening / closing operation means of the present embodiment is such that, for example, one tow rope 12 is used to open / close the awning sheets 4 in three sections at the same time. The tow rope 12 forms an endless ring shape, is hung on a large number of rope traveling guide pulleys 41 mounted on the girder frame 3, and is laid around once, while being operated by the awning user. A part is hung along an arbitrary support column 2.

A large number of rope traveling guide pulleys 41 are arranged on the upper surface of the girder frame 3 so that the tow rope 12 is routed along the arcuate girder frame 3. For example, in the case of the present embodiment, the girder frame 3 is divided into three in the circumferential direction, and eight rope traveling guide pulleys 41 are provided at intervals of 15 ° for each girder frame 3 to be stretched. The ropes 12 are arranged so as to form a heptagon and a 24-sided polygon in each section, and are configured to form a polygon similar to a circle.

Here, since the annular frame 1 has three arcuate girder frames 3 connected by sandwiching the three columns 2 to form an annular shape, the category in which the awning sheet 4 opens and closes is divided by the columns 2. Confined to each area of the two compartments. Therefore, the tow rope 12 is provided so as to be detoured behind the support column 2 (inside in the radial direction) and routed on the adjacent girder frame 3 at the intersection of the girder frame 3 and the support column 2. For example, by arranging the direction change guide pulley 42 on the side surface of the beam frame 5, the tow rope 12 is passed from the rope traveling guide pulley 41 of the girder frame 3 to the direction change guide pulley 42 on the side surface of the beam frame 5. It is passed through between the rafter frame 6 and the beam frame 5 so as to be routed to the rope traveling guide pulley 41 on the adjacent girder frame 3.

Thus, the tow rope 12 is routed within a range within the width of the annular girder frame 3 and stretched so as to make one round. That is, the tow rope 12 does not protrude from the girder frame 3 when viewed from below. Moreover, since the tow rope 12 is stretched around within the width of the annular girder frame 3 and stretched in a polygonal shape close to a circle, the awning frame 18 is stretched regardless of the position of the awning frame 18. It is possible to apply a traction force almost in the tangential direction. Therefore, the awning frame 18 can be routed without applying unnecessary force. Of course, the number and arrangement positions 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 arranged at appropriate positions as needed. ..

Further, a part of the tow rope 12 is hung along the support column 2 so that it can be operated by the awning user. For example, a direction changing guide pulley 42 that guides the tow rope 12 in the horizontal direction from above the girder frame 3 to the beam frame 5 side and a vertical guide pulley 43 that guides the tow rope 12 in the vertical direction are on both left and right sides of the beam frame 5. A part of the tow rope 12 is routed so as to hang down along the support column 2. The support column 2 where the tow rope 12 is hung is provided with a rope fixing device 44 and a pre-tensioning device 45 for loosening the rope, and the tow rope 12 is fixed at an arbitrary position. Tension is constantly applied so that slack does not occur.

As the rope fixing device 44, for example, a rope stopper called a clam cleat is used. In this crumb cleat, for example, a V-shaped (wedge-shaped) groove is formed between two facing faces, and one or two or more return ridges (in other words, in other words) for increasing friction are formed on both wedge-shaped slopes. The groove) is formed so as to intersect the moving direction of the rope, and the tow rope 12 is fitted into the wedge-shaped groove to fix the movement of the tow rope 12 by friction. Since the width of the wedge-shaped groove becomes narrower toward the bottom of the groove, if the clam cleat is installed so that the position where the hanging tow rope 12 is pulled straight is near the bottom of the groove, the tow rope 12 The more tension is applied to the rope, the deeper it goes into the groove and the easier it is to stop. That is, the tow rope 12 is firmly held by simply hanging the tow rope 12 lightly on the groove, and the tow rope 12 can be easily fixed.

This crumb cleat applies a binding force only in one direction. For example, as shown in FIG. 14, when the tow rope 12 that moves upward is installed so as to be fixed, the crumb cleat is in the upward direction (direction of the arrow B). Only the rope that moves to can be fixed, and when the rope is pulled down (in the direction of the arrow A), the fixing is released. Therefore, when opening and closing the awning, the tow rope 12 is simply pulled downward, or the rope is pulled out from the groove of the clam cleat and moved in an arbitrary direction. Then, when it is desired to fix the awning at an arbitrary position, the tow rope 12 is fixed by simply pushing it lightly into the groove of the clam cleat. Therefore, the awning sheet 4 can be fixed in the stored state and the unfolded state, and at any position and angle between them.

On the other hand, the pre-tensioning device 45 eliminates the looseness of the tow rope 12 by constantly applying tension to the tow rope 12, and prevents the tow rope 12 drawn around by the rope traveling guide pulley 41 or the like from falling off. The purpose is to prevent the awning sheet 4 from rattling in the circumferential direction. For example, a pulley around which the tow rope 12 is wound and a tension spring 47 interposed between the pulley and the support column 2. The pulley 46 is provided so as to be constantly pulled by the pulling spring 47. Reference numeral 48 in the drawing is a hook fixed to the support column 2.

According to the opening / closing operation means configured as described above, when the sunshade sheet 4 in the stored state shown in FIGS. 15A and 2 is unfolded, the index rope 12 is operated in the A direction shown in FIG. As a result, the tow rope 12 can be rotated in the forward direction (counterclockwise rotation direction in FIG. 1) as a whole. Moreover, since the tow rope 12 is routed along the contour of the girder frame 3, a traction force can be applied to the awning frame 18 in the tangential direction. That is, the traction force can be applied in the direction orthogonal to the awning frame 18 (tangential direction). Therefore, the degree of application of the traction force is constant and the operability is good, and all of the traction force can be applied without waste with respect to the opening / closing operation of the awning frame 18.

Moreover, since the end portion on the inner peripheral side of the awning frame 18 is supported by the rotating shaft 20 and the outer peripheral side is supported by the slide means 21, the operating force for opening and closing can be reduced. Therefore, by operating only one tow rope 12, it is possible to easily open and close the three awning sheets 4 at the same time with a light operating force. Moreover, since the tow rope 12 is routed along the contour of the girder frame 3 by the rope traveling guide pulley 41 arranged on the upper surface of the girder frame 3, the tow rope 12 can be routed so as not to be seen from below.

Further, when the tow rope 12 moves forward and the leading awning frame 18 is pulled forward, the subsequent awning frames 18 are also connected to each other by the sheet-shaped member 19, so that the leading awning frame 18 is continued. The other awning frames 18 are also pulled out in sequence, and the awning sheet 4 is deployed. Since the rearmost awning frame 18 is fixed to the support column 2 or the girder frame 3, when the first awning frame 18 reaches the front support column 2, each sheet shape between all the awning frames 18 is formed. The member 19 is in a stretched state and is kept in a substantially horizontal state without slack. Here, "stretching the sheet-shaped member 19 in a substantially horizontal state" includes, of course, including the case where the sheet-shaped member 19 is stretched so as to be horizontal without slack, and is stretched gently to the extent that there is no sagging. It is also included if it is.

Further, when the awning sheet 4 in the unfolded state shown in FIGS. 15 (B) and 1 is stored, the tow rope 12 is operated in the B direction shown in FIG. 14 to move the tow rope 12 backward (FIG. 1). In the clockwise direction). As a result, the leading awning frame 18 connected to the tow rope 12 moves backward, hits the subsequent awning frames 18 one after another, pushes back, and moves until it comes into contact with the fixed awning frame 18 at the rear end. .. At this time, the sheet-shaped member 19 between the awning frames 18 hangs down and is folded. As a result, the awning sheet 4 is brought close to the bottom of the storage cover 11 and stored.

Normally, in the case of an awning for outdoor use, the awning frame 18 for suspending the sheet-shaped member 19 needs to have a high cross-sectional shape to increase the moment of inertia of area in order to increase the bending strength. For this reason, when the base end portions of the awning frame 18 are connected by one rotating shaft 20 to open and close in a fan shape, interference between the awning frames 18 occurs when the fan is close to the main part, which causes interference. There is a problem that the angle of the fan cannot be narrowed more than that. That is, when the awning sheets 4 are stored, if the awning frames 18 interfere with each other on the inner peripheral end side, a space is opened between the adjacent awning frames 18 on the outer peripheral end side, so that the awning sheets cannot be stored compactly and a storage space is taken. There is. However, in the awning sheet 4 of the present embodiment, the tilt angles of the awning frames 18 are alternately different, and the awning sheets 4 are distributed up and down so as not to interfere with each other in the vicinity of the essential rotation shaft 20, so that the awning sheet 4 has a narrow angle. Can be folded and stored compactly.

The awning sheet 4 can freely change the opening degree from the retracted state to the deployed state or vice versa by operating the tow rope 12, and the tow rope 12 is fixed to the support column 2. Can be fixed at any position and at any opening.

According to the above-described embodiment, it is possible to provide an awning of an unprecedented novel movement in which the awning sheet 4 is opened and closed in a fan shape in a horizontal plane along the annular frame 1. Moreover, it is possible to realize an interesting movement of opening and closing at the same time in a plurality of sections, and since the awning sheet 4 is opened and closed at the same time in each section, it is possible to provide an awning that does not take time to deploy and store (fully open and fully closed).

The above-mentioned 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 made without departing from the gist of the present invention.

For example, in the above-described embodiment, the awning frame 18 has a structure in which the awning frame 18 is alternately distributed in two upper and lower rows on the base end (root) side, but the structure is not particularly limited to this, and in some cases, the upper, middle, and lower 3 are distributed. It may be divided into rows or three or more rows. That is, by dividing the positions of the plates fitted to the rotating shaft 20 into three or more locations and sequentially distributing them, it is possible to further suppress interference on the base end side of the awning frame 18. That is, the end portion on the inner peripheral side is rotatably connected so as to be sequentially distributed and stacked at different height positions of the rotating shaft 20 arranged at the center of curvature of the girder frame 3 via the connecting plate 25, and the awning frame. The inclination angles of 18 are different from each other, and it is sufficient that they are distributed in the vertical direction so as not to interfere with each other in the vicinity of the essential rotation shaft 20.

Further, in the above-described embodiment, the awning sheet 4 is provided so that the sheet-shaped member 19 is stretched and stretched horizontally when unfolded, but the present invention is not particularly limited to the sheet-shaped member 19. The member 19 may be unfolded with a slack. For example, as shown in FIG. 16, by directly connecting adjacent awning frames 18 with a tape-shaped connecting member 49 shorter than the width of the sheet-shaped member 19, the next awning frame is placed before the sheet-shaped member 19 is tense. As a structure in which the 18 is pulled out, the awning frames 18 adjacent to each other may be pulled and expanded by the tape-shaped connecting member 49. In this case, the space between the adjacent awning frames 18 and the awning frame 18 is maintained at a constant distance by the tape-shaped connecting member 49 being stretched before the sheet-shaped member 19 is stretched, so that the adjacent awning frames 18 are stretched. The sheet-like member 19 can form a graceful fold with sagging between them.

Further, in the above-described embodiment, the support structure is such that the awning frame 18 is suspended under the annular girder frame 3 by the slide means 21, but the structure is not particularly limited to this, and the guide rail of the girder frame 3 may be used in some cases. The tip of the awning frame 18 may be housed inside the portion 3b and slidably supported, or the tip of the awning frame 18 may be placed on the girder frame 3 to support it.

Further, in the above-described embodiment, the three arc-shaped girder frames 3 are connected with the support column 2 sandwiched between them to form a non-perfect circular ring having three centers of curvature, but the present invention is not particularly limited to this. For example, by supporting the annular girder frame 3 made of one perfect circle so as to be supported by the support column 2, the moving range of the awning frame 18 may be substantially one round. That is, a circular awning may be formed by one awning sheet 4 that opens and closes so that the leading awning frame 18 makes substantially one revolution around one rotating shaft 20. Further, when the plurality of girder frames 3 and the fan-shaped awning sheet 4 are combined, the combination is not limited to the combination of the three awning sheets 4 and the like, and two sections may be formed by connecting two arcs, and further four. One circular awning may be formed as a whole as four or more sections in which the above arcs are connected. Further, in the above-described embodiment, a case where a plurality of girder frames 3 and a fan-shaped awning sheet 4 are combined to form a circular awning as a whole has been mainly described, but the present invention is not particularly limited to this. A fan shape composed of a set of frame units and a sunshade sheet For example, it can be configured as an awning of one section (angle 120 °) of the above-described embodiment, or a combination of multiple sets of units can be combined into a semicircle or 360 in a semicircle or more. It may be configured as a fan-shaped awning of less than °. The angle of one fan-shaped section composed of a set of frame units and a sunshade sheet is not particularly limited to about 120 ° in the figure, and may be a larger angle, or a small angle such as 90 °. Further, it may be formed at any angle smaller than 60 °.

Further, in the above-described embodiment, the operation mechanism is used to open and close the awning sheet 4 in three sections at the same time with one tow rope 12, but the present invention is not particularly limited to this, and in some cases, each awning sheet 4 in each section is used. By providing an operation mechanism in each section, the awning sheet 4 may be opened and closed independently for each section.

Further, in the above-described embodiment, the connecting plate 25 at the base end portion of the awning frame 18 is alternately distributed to the upper side 20b and the lower side 20a of the rotating shaft 20 and fitted to different height positions to be connected. By making the bending depth of the connecting plate 25 of the awning frame 18 different for each sheet, the base end side of the awning frame 18 is arranged in two horizontal rows of the upper row and the lower row. It is not limited, for example, by making each connecting plate 25 a straight plate without bending, the arrangement of a plurality of awning frames 18 distributed in two upper and lower rows depends on the height position connected to the rotation shaft 20. The diagonal arrangement may be such that the height is increased by one step. Even in this case, since the awning frames 18 can be closed until they come into contact with each other on the outer peripheral end side by eliminating the interference of the awning frames 18 near the rotating shaft 20 of the awning sheet 4, the awning sheet 4 can be closed when it is stored. The width can be closed in a triangular or fan shape to the minimum. Therefore, the difference in opening between when the awning sheet 4 is deployed and when it is stored can be further widened as compared with the conventional case.

Further, in the above-described embodiment, the dimensions of the sheet-shaped members 19, particularly the width (length in the circumferential direction) are made the same, and the distance between the awning frames 18 when the awning sheet 4 is opened is the same. , The length is not particularly limited to this, and may be different depending on the case. Of course, regarding the radial length, it is preferable to make the length of the sheet-like member 19 uniform with the length that closes between the girder frame 3 and the rainwater receiver 13 in order not to impair the function as a sunshade. Needless to say.
