Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to roof technology, and more specifically, to a tension-type roof capable of easily applying tension to an awning.

To enjoy camping, a tent is one of the essential tools that protects you from the elements and provides a safe bed. In addition, tarps that expand the living space from the tent are also favored by campers. Tents and tarps are different in that while tents have an overwhelming waterproof function to withstand wind and rain, tarps are not required to be so waterproof, and tents have a floor structure. The two are different in that the tarp does not have this, but they are common in that they both have a sheet-like "tent" that covers the sky above the living space.

In recent years, tents and tarps have also been attracting attention as measures against heatstroke. Frequent hydration and salt replenishment are essential to prevent heatstroke, but avoiding the sun is also effective, so set up a temporary shelter with a tent or tarp to avoid the sun. This is a countermeasure against heatstroke. In particular, infants are less skilled at regulating their body temperature than adults, so it is expected that installing a tarp in advance will be an effective measure against heat stroke when they are active in the open space (playground or playground) of a kindergarten, nursery school, elementary school, etc. in the summer. can.

On the other hand, if tents and tarps are permanently set up, it is not preferable because it limits the area that can be used in open spaces such as nursery schools. is. Therefore, it is desirable to have a tarp that can be easily moved, installed and removed easily, and that can be stored without being bulky. In this respect, a tarp is more suitable than a tent.

In this way, it is expected that the demand for tents and tarps will increase in the future, and it is conceivable that the technology will be improved in order to pursue further convenience. Various techniques for improving tents and tarps have been proposed so far. For example, Patent Literature 1 proposes a tarp that can be combined with a tent without deteriorating aesthetic appearance and safety.

JP-A-2001-107604 Japanese Patent No. 5711419

The tarp disclosed in Patent Document 1 can be said to be a suitable technique in that its shape and dimensions can be changed relatively easily. However, it can be pointed out that the tarp of Patent Literature 1 cannot apply tension to its awning. The awning that makes up a tarp or tent is desirably under tension when in use. If the awning is used in a state where no tension is applied to the awning, as in the case of the tarp of Patent Document 1, the awning is easily fluttered by the wind, resulting in significant deterioration in the usage environment, such as noise. In addition, as a result of no tension being applied to the awning, the structure of the entire tarp becomes unstable, and there is even a risk of it easily collapsing even with some load (wind, rain, unexpected collision, etc.). Furthermore, it is known that the roof structure is particularly stable if the roof is made into a single-leaf hyperboloid shape (so to speak, a shape like potato chips) as shown in Patent Document 2. As shown in FIG. 12, this one-leaf hyperboloid exhibits a downwardly convex catenary curve in the cross section along the short axis direction (XX) of the roof, and an upwardly convex catenary curve in the cross section along the long axis direction (YY). Although it is a shape that shows a curve, if you try to realize this with a tarp or tent awning, it is necessary to introduce tension into the awning.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the problems of the prior art, namely to provide a tensioned roof that allows the awning to be easily tensioned during use.

The invention of the present application was developed by paying attention to the fact that the awning is stretched while applying tension to it by pulling the branch shafts on which the awning is installed. It is an invented invention.

The tension-type roof of the present invention includes a main shaft member arranged in the center, branch shaft members composed of a left branch shaft member and a right branch shaft member, tension rope members fixed to the branch shaft members, and attached to the upper part of the branch shaft members. It has a tent. Two or more branch shaft members are attached to the main shaft member, and each branch member is arranged in a V shape that opens forward by the left branch shaft member and the right branch shaft member. In addition, the tension rope connects the left and right branch shafts that are adjacent to each other in the front and rear, and is fixed so as to extend further rearward from the rearmost left and right branch shafts. When the tension rope is pulled rearward, the tip of the branch shaft expands rearward and away from the main shaft, thereby expanding the awning.

The tension-type roof of the present invention may further comprise a left telescopic means and a right telescopic means capable of being stretched in the axial direction. This left expansion and contraction means is arranged in a direction (however, the direction projected on the horizontal plane) different from the direction of arrangement of the left branch shaft (however, the direction projected on the horizontal plane), ), and the other end is pinned to the left branch shaft so as to be rotatable about a substantially vertical plane (including the vertical plane). Similarly, the right expansion and contraction means is arranged in a direction (however, the direction projected on the horizontal plane) different from the arrangement direction of the right branch shaft (however, the direction projected on the horizontal plane), and one end is substantially vertical plane (vertical plane ), and the other end is pinned to the right branch shaft so as to be rotatable about a substantially vertical plane (including the vertical plane). The left branch shaft member and the right branch shaft member are pin-coupled to the main shaft member so as to be rotatable around a substantially vertical plane (including a vertical plane). When the left expansion/contraction means expands, the left branch shaft rotates upward, when the left expansion/contraction means contracts, the left branch shaft rotates downward, and when the right expansion/contraction means expands, the right branch shaft rotates upward. When the right expansion means contracts, the right branch shaft member rotates downward.

In the tension type roof of the present invention, the left branch shaft member has a first left branch shaft member and a second left branch shaft member, and the right branch shaft member has a first right branch shaft member and a second right branch shaft member. can also One end of the first left branch shaft member is pin-coupled to the main shaft member, and the other end of the first left branch shaft member is provided with a second left branch shaft member so as to be rotatable around a substantially vertical plane (including a vertical plane). One end of the first right-hand branch shaft is pin-connected to the main shaft, and the other end of the first right-hand branch shaft is rotatable about a substantially vertical plane (including a vertical plane). The right branch shaft is pinned. The left telescopic means is pin-connected to the second left branch shaft, and the right telescopic means is pin-connected to the second right branch shaft. When the left expansion/contraction means contracts, the first left branch shaft member and the second left branch shaft member are folded into a V-shape. The shaft member is folded into a V shape.

The tensioned roof of the present invention may further include a left sub-shaft and a right sub-shaft. This left sub-shaft member connects a plurality of left-branch shaft members at the joint position between the first left-branch shaft member and the second left-branch shaft member. A plurality of right branch shaft members are connected at a joint position with 2 right branch shaft members.

The tension roof of the present invention may further comprise a left auxiliary arm and a right auxiliary arm. One end of the left auxiliary arm is pin-coupled to the left telescopic means so as to be rotatable around a substantially vertical plane (including a vertical plane), and the other end is rotatable around a substantially vertical plane (including a vertical plane). One right auxiliary arm is pin-coupled to the right telescopic means so that one end can rotate around a substantially vertical plane (including a vertical plane), The other end is pin-coupled to the first right branch shaft so as to be rotatable around a substantially vertical plane (including a vertical plane).

The tension-type roof of the present invention is sandwiched between the left access control member installed so as to be sandwiched between the left expansion means and the second left branch shaft member, and the right expansion means and the second right branch shaft member. A right access control member installed as described above may be further provided. This left access control member controls the approach of the left expansion means and the left branch shaft member when the left expansion means is extended, while the right access control member controls the right expansion means when the right expansion means is expanded. and the right branch shaft.

The tension-type roof of the present invention may further include a rotation control member installed between the left branch shaft member and the right branch shaft member. This rotation control member controls the downward rotation of the first left branch shaft when the left telescopic means contracts, and controls the downward rotation of the first right branch shaft when the right telescopic means contracts. .

The tensioned roof of the present invention may further comprise connecting ropes and opening control members. This connecting rope member connects the first left branch shaft member and the first right branch shaft member, and one of the opening control members is between the first left branch shaft member and the first right branch shaft member. It is installed above the connecting rope. Then, when the first left branch shaft and the first right branch shaft rotate upward, the opening control member restricts the upward movement of the connecting rope member, so that the first left branch shaft and the first right branch shaft rotation is restricted.

The tension-type roof of the present invention can also be one in which the opening control member is installed so as to be movable up and down. In this case, the upper limit of rotation of the first left branch shaft member and the first right branch shaft member can be adjusted by changing the installation position of the opening control member.

The tension-type roof of the present invention has the following effects.
(1) Tension can be easily applied to the awning during use by pulling the branch shafts.
(2) By providing the left stretchable means and the right stretchable means, the whole can be folded in half, that is, it can be easily stored without being bulky when not in use.
(3) The upper limit of the rotation angle of the awning (the angle in the vertical plane) during use can be arbitrarily adjusted by providing the connecting rope member and the opening control member that can move up and down.

1. General Overview FIG. 1 is a diagram schematically showing a tensioned roof 100 of the present invention, (a) is a plan view seen from above, (b) is a side view seen from the side, and (c) is a vertical plane. 1 is a cross-sectional view taken from the front and cut at . As shown in this figure, the mobile roof structure 100 of the present invention comprises a frame structure 200 , a tension rope 300 , an awning 400 , and may further comprise a support 500 . For the sake of convenience, as shown in FIG. 1(a), the longitudinal direction (horizontal direction in the drawing) of the tension type roof 100 is referred to as the "main axis direction", and the direction perpendicular to the main axis direction (vertical direction in the drawing). ) is referred to as the "perpendicular direction to the main axis". However, the direction of the main axis and the direction perpendicular to the main axis are directions set on the horizontal plane. One side (the left side in the figure) of the direction perpendicular to the main axis is called "forward", and the other side (the right side in the figure) is called "rear".

The frame structure 200 supports the awning 400, and is a structure configured like a frame by main shaft members and branch shaft members (or sub shaft members), which will be described later. These main shafts, branch shafts, and sub shafts are so-called shaft members whose axial dimension (length) is outstanding compared to their cross-sectional dimensions. parallel). The awning 400 is a sheet-like (membrane-like) member that can cover the lower side in a stretched state, thereby protecting the space under the awning 400 (so-called staying space) from strong sunlight and rainfall. Also, the tension rope member 300 is a rod-like member such as a wire rope or string, and is tied to each branch shaft member (especially near the tip thereof). As will be described later, when the pulling cable 300 is pulled rearward, the tip of the branch shaft expands and moves rearward.

The support body 500 supports the frame structure 200 and the awning 400 so that a predetermined staying space is secured under the awning 400 (that is, at a considerable height), and is a supporting body that transmits a vertical load to the ground. 510 and support jacks 520 that support the frame structure 200 in an auxiliary manner. In FIG. 1B, the support 500 is arranged on the rear side to support the frame structure 200 and the awning 400 in a so-called cantilever manner. can be arranged to support the frame structure 200 and the awning 400 in a simple beam format (two-point support format), or the frame structure 200 and the awning 400 can be supported by a plurality of struts (tubular or columnar members) arranged around them. can also support In addition, in FIG. 1(c), the awning 400 is extended in a curved shape that protrudes downward, but is not limited to this, and as shown in FIG. It can also be expanded. In this case, as shown in FIG. 2(b), the support 500 is further provided with a cable tower 530 and a suspension rope 540, and the suspension rope 540 supported by the cable tower 530 on the support body 510 is positioned at the center of the awning 400 (main axis). It is preferable to have a structure in which the center in the perpendicular direction is lifted. Alternatively, instead of the structure in which the central part of the awning 400 is lifted over the entire length by the suspension ropes 540, a structure in which the front end and the rear end of the awning 400 are lifted by the suspension ropes 540 may be employed.

Below, the tension type roof 100 of the present invention will be described in more detail.

2. Tensioned Roof FIG. 3 is a diagram schematically showing a tensioned roof 100 having a frame structure 200 composed of main shaft members 210 and branch shaft members 220, and is a plan view from above. The frame structure 200 that constitutes the mobile roof structure 100 is a structure configured like a frame by the main shaft members 210 and the branch shaft members 220 as described above, of which the branch shaft members 220 are shown in FIG. It is a member consisting of a combination of a pair of left branch shaft member 220L and right branch shaft member 220R.

A plurality (four pairs in the figure) of branch shaft members 220 are arranged side by side in the main shaft direction and attached to the main shaft member 210 . More specifically, one end of the left branch shaft member 220L (the right end in the drawing, hereinafter referred to as the “inner end”) is attached to the main shaft member 210, and one end of the right branch shaft member 220R (the left end in the drawing, hereinafter referred to as the “inner end”) is attached to the main shaft member 210. ) is attached to the main shaft member 210 , the branch shaft member 220 is attached to the main shaft member 210 . At this time, the other end of the right branch shaft member 220R (the right end in the drawing) is similarly positioned so that the other end of the left branch shaft member 220L (the left end in the figure, hereinafter referred to as the “outer end”) is positioned forward of the inner end. , hereinafter referred to as the "outer end") is located forward of the inner end, that is, the left branch shaft member 220L and the right branch shaft member 220R form a "forward-opening V". , and attached to the main shaft member 210 respectively.

The tension rope 300 is tied to the branch shaft 220 at a position near the outer end, and is mainly composed of a left channel connecting the left branch shafts 220L and a right channel connecting the right branch shafts 220R. be. The tension rope 300 of the left path connects the left branch shafts 220L that are adjacent in the main axis direction, and is installed so as to extend further rearward after being tied to the left branch shaft 220L that is the rearmost (the lowest end in FIG. 3). be done. Similarly, the tension rope member 300 of the right path connects the right branch shaft members 220R adjacent in the main axis direction, and is installed so as to extend further rearward after being tied to the rearmost right branch shaft member 220R. . The tension cable 300 is configured to extend in each section (left branch shaft 220L to left branch shaft 220L and right branch shaft 220R to right branch shaft 220R), and the amount of elongation of the tension cable 300 ( In other words, the moving distance of the tip of the branch shaft 220 gradually increases from the front section and becomes maximum at the rearmost section. As shown in FIG. 3, the tip side of the tension cable 300 may connect the front side of the main shaft 210 and the most forward (uppermost in the figure) left branch shaft 220L or right branch shaft 220R. . In addition, the tension rope 300 of the left path can be a series of members (that is, one rope), or can be independent for each section (left branch shaft 220L to left branch shaft 220L) (that is, A plurality of ropes can be prepared and connected, and of course the pulling ropes 300 of the right path can be similarly configured.

The awning 400 is a sheet-like (membrane-like) member having a size (area) and shape that generally covers the frame structure 200 , and is attached to the upper part of each branch shaft member 220 . For the awning 400, various conventionally used materials such as cloth curtains and vinyl sheets, blindfold sheets used to hide scaffolding, and cheesecloth can be used.

FIG. 4 is a diagram schematically showing the behavior of the branch shaft member 220, and is a plan view seen from above. For the sake of convenience, the awning 400 is omitted in this figure. As shown in this figure (particularly by arrows), when the pulling cable 300 is pulled (pulled) rearward, the branch shaft 220 expands. More specifically, the outer end of the left branch shaft member 220L moves away from the main shaft member 210 (to the left in the figure) and also moves rearward (downward in the figure). The end is in the direction away from the main shaft member 210 (right side in the drawing) and moves backward. When the branch shaft member 220 is expanded, the awning 400 attached to the upper part of the branch shaft member 220 is also expanded. That is, by pulling the tow ropes 300 rearward, considerable tension is introduced into the awning 400 . A winding device such as a winch or a hoist can be used to pull the pulling cable 300 to the rear side, and of course, it can also be pulled by human power.

As described above, when the tension rope 300 is pulled rearward, the outer ends of the branch shafts 220 move rearward away from the main shaft 210 . On the other hand, the inner end of the branch shaft 220 is connected to the main shaft 210 . In other words, the branch shaft member 220 moves so as to rotate around the inner end as the pulling cable member 300 is pulled. For example, the left branch shaft member 220L shown in FIG. 4 rotates counterclockwise about the inner end, and the right branch shaft member 220R rotates clockwise about the inner end. Therefore, the branch shaft members 220 (the left branch shaft member 220L and the right branch shaft member 220R) are attached to the main shaft member 210 so as to be rotatable. However, the type of connection between the inner end of the branch shaft member 220 and the main shaft member 210 is not necessarily limited to a pin connection (hinge connection) (of course, a pin connection may also be used), and may be a connection type in which a rotating spring is generated. . In this case, the branch shaft 220 cannot rotate freely with respect to the main shaft 210, but can rotate according to the magnitude of the force (rotational moment) when a certain amount of force (rotational moment) acts.

The tension type roof 100 of the present invention can also be provided with a left elastic means 600L and a right elastic means 600R as shown in FIG. FIG. 5 is a diagram schematically showing the tension type roof 100 provided with the left elastic means 600L and the right elastic means 600R, and is a plan view seen from above. The left telescopic means 600L and the right telescopic means 600R are devices capable of extending and retracting in the axial direction, and for example, jacks or the like can be used. In addition, as shown in this figure, the main shaft member 210 can also be partially configured by two (three or more) shaft members (partially on the lower side in the figure).

The left expansion/contraction means 600L is pin-coupled to a part of the main shaft member 210 so that its inner end (right end in the figure) can rotate around a substantially vertical plane (including a vertical plane), and its outer end (right end in the figure) The left end) is pin-coupled to a portion of the left branch shaft member 220L so as to be rotatable around a substantially vertical plane (including the vertical plane). Similarly, the right expansion/contraction means 600R is pin-coupled to a portion of the main shaft member 210 so that its inner end (left end in the figure) can rotate around a substantially vertical plane (including a vertical plane), and its outer end It is pin-connected to a part of the right branch shaft member 220R so as to be rotatable around a substantially vertical plane (including the vertical plane) at (the right end in the figure). However, the left expansion/contraction means 600L and the left branch shaft 220L, and the right expansion/contraction means 600R and the right branch shaft 220R are arranged in different directions (directions projected onto the horizontal plane). For example, in FIG. 5, the left branch shaft member 220L is arranged obliquely to the main shaft member 210 (toward the front left side), whereas the left expansion/contraction means 600L is arranged substantially perpendicular to the main shaft member 210. The right branch shaft member 220R is arranged obliquely to the main shaft member 210 (toward the front right side), whereas the right expansion/contraction means 600R is arranged substantially perpendicular to the main shaft member 210. As shown in FIG.

If the tensioned roof 100 includes a left telescoping means 600L and a right telescoping means 600R, the branch shaft 220 may be pinned to the main shaft 210 so as to be rotatable about a substantially vertical plane (including vertical planes). More specifically, the inner end of the left branch shaft member 220L and part of the main shaft member 210 are pin-connected, and the inner end of the right branch shaft member 220R and part of the main shaft member 210 are pin-connected. As a result, the left branch shaft member 220L and the right branch shaft member 220R can be expanded and folded according to the expansion and contraction of the left expansion and contraction means 600L and the right expansion and contraction means 600R.

6A and 6B are vertical cross-sectional views schematically showing the movement of the branch shaft member 220 accompanying expansion and contraction of the left expansion mechanism 600L and the right expansion mechanism 600R. A state in which the member 220R is folded is shown, and (b) shows a state in which the left branch shaft member 220L and the right branch shaft member 220R are unfolded. In FIG. 6(a), the left elastic means 600L and the right elastic means 600R are contracted, so that the left branch shaft member 220L and the right branch shaft member 220R are in a slightly downward state, that is, the left branch shaft member 220L and the right branch shaft member 220R. The right branch shaft member 220R is in a folded state. When the left elastic means 600L and the right elastic means 600R are extended from this state, as shown in FIG. The shaft member 220R rotates counterclockwise upward around the inner end, that is, the left branch shaft member 220L and the right branch shaft member 220R are expanded.

On the other hand, when the left elastic means 600L and the right elastic means 600R are contracted from the state shown in FIG. The member 220R rotates downward clockwise around the inner end, that is, the left branch member 220L and the right branch member 220R are folded as shown in FIG. 6(a).

The tension-type roof 100 of the present invention, as shown in FIG. It can also be configured to include the shaft member 221R and the second right branch shaft member 222R. FIG. 7 is a diagram schematically showing a tensioned roof 100 provided with a branch shaft member 220 consisting of two members (a first left branch shaft member and a second branch shaft member), and (a) is cut along a vertical plane. A cross-sectional view, and (b) is a partially enlarged plan view of a joint portion of two members (a first left branch shaft member and a second branch shaft member) viewed from above.

The left branch shaft member 220L shown in FIG. 7A includes a first left branch shaft member 221L arranged on the side of the main shaft member 210 (right side in the drawing) and a left branch shaft member 221L arranged on the side away from the main shaft member 210 (left side in the drawing). It is constituted by the second left branch shaft member 222L, and one end of the first left branch shaft member 221L (the left end in the figure) and one end of the second left branch shaft member 222L (the right end in the figure) rotate around a substantially vertical plane (including a vertical plane). Pinned as possible. Similarly, the right branch shaft member 220R includes a first right branch shaft member 221R arranged on the side of the main shaft member 210 (left side in the drawing) and a second right branch shaft member 221R arranged on the side away from the main shaft member 210 (right side in the drawing). One end of the first right branch shaft member 221R (the right end in the drawing) and one end of the second right branch shaft member 222R (the left end in the drawing) are arranged around a substantially vertical plane (including a vertical plane). It is pinned so that it can rotate. Although the second left branch shaft member 222L can be pin-connected to the first left branch shaft member 221L so as to be rotatable by 360°, the second left branch shaft member 222L and the first left branch shaft member 221L are straight. It is also possible to connect with a pin so as not to rotate afterwards (that is, to prevent only the second left branch shaft member 222L from rotating clockwise from the state of FIG. 7(a)). Of course, the second right branch shaft member 222R can also be pin-connected to the first right branch shaft member 221R with a similar structure.

When the branch shaft 220 (left branch shaft 220L and right branch shaft 220R) is composed of two members (first left branch shaft and second branch shaft), as shown in FIG. A connecting rope member 710, an opening control member 720, and a rotation control member 730 may be arranged between 220L and the right branch shaft member 220R. The connecting rope member 710 is a rod-like member (for example, a wire rope) that connects the left branch shaft member 220L and the right branch shaft member 220R. The functions of the connecting cable member 710, the opening control member 720, and the rotation control member 730 will be described later.

Further, in this case, the left elastic means 600L and the right elastic means 600R are pin-coupled to the second branch shaft member so as to be rotatable around a substantially vertical plane (including a vertical plane). More specifically, the outer end of the left elastic means 600L (the left end in the figure) and part of the second left branch shaft member 222L are pin-connected, and the outer end of the right elastic means 600R (the right end in the figure) 2 A part of the right branch shaft member 222R is pin-connected. In the example of FIG. 7, after attaching the left locking tool 601L to the outer end of the left elastic means 600L, the left locking tool 601L and the second left branch shaft member 222L are pin-connected, and the outer end of the right elastic means 600L is attached. After attaching the right locking device 601R, the right locking device 601R and the second right branch shaft member 222R are pin-connected. Further, in the example of FIG. 7, a left auxiliary arm 602L and a right auxiliary arm 602R are provided. The other end (upper end in the figure) of the left auxiliary arm 602L and the first left branch shaft member 221L are connected to a substantially vertical plane (including the vertical plane) while being pinned so as to be rotatable around a plane (including the vertical plane). One end (lower end in the figure) of the right auxiliary arm 602R and the second right branch shaft member 222R (or the right locking member 601R) are connected around a substantially vertical plane (including a vertical plane). and the other end (upper end in the drawing) of the right auxiliary arm 602R and the first right branch shaft member 221R are rotatable around a substantially vertical plane (including a vertical plane). is pinned to

Here, with reference to FIG. 7(b), an example of the joint structure between the first right branch shaft member 221R and the second right branch shaft member 222R will be described in more detail. Since the first left branch shaft member 221L and the second left branch shaft member 222L also have the same joint structure, the first right branch shaft member 221R and the second right branch shaft member 222R will be explained here as an example. In the example of this figure, a first right joint plate 223R and a second right joint plate 224R are provided, and these first right joint plate 223R and second right joint plate 224R are rotatably joined by a right hinge 225R. The outer end of the first right branch shaft member 221R is fixed to the first right joint plate 223R, and the inner end of the second right branch shaft member 222R is fixed to the second right joint plate 224R. The first right branch shaft member 221R and the second right branch shaft member 222R are rotatably coupled. In addition, the right locking tool 601R is pin-connected to the second right joint plate 224R, the right auxiliary arm 602R is pin-connected to the first right branch shaft member 221R, and the right locking tool 601R and the right auxiliary arm 602R are pin-connected. The right locking device 601R and the second right branch shaft member 222R, the right auxiliary arm 602R and the first right branch shaft member 221R, and the right locking device 601R and the right auxiliary arm 602R are each rotatable. is coupled to

If the branch shaft 220 (the left branch shaft 220L and the right branch shaft 220R) is composed of two members (the first left branch shaft and the second branch shaft), the awning 400 and the like are bent at the joints of the two members. Become. Therefore, in this case, as shown in FIG. 8, it is preferable to install linear left sub-shaft member 230L and right sub-shaft member 230R as guides for neat folding. Of course, the left sub-shaft member 230L and the right sub-shaft member 230R can also be expected as structural reinforcing members. FIG. 8 is a diagram schematically showing the tensioned roof 100 provided with the left secondary shaft 230L and the right secondary shaft 230R, and is a plan view seen from above. As described above, the left sub-shaft member 230L and the right sub-shaft member 230R are members that form the frame structure 200 together with the main shaft member 210 and the branch shaft member 220, and are shafts whose axial dimensions are superior to their cross-sectional dimensions. It is a member. As shown in this figure, the left sub-shaft member 230L is arranged generally in the direction of the main axis, and connects the plurality of left-hand branch shaft members 220L at the joining position between the first left-hand branch shaft member 221L and the second left-hand branch shaft member 222L. The secondary shaft member 230R is arranged generally in the direction of the main shaft, and connects the plurality of right branch shaft members 220R at the joining position between the first right branch shaft member 221R and the second right branch shaft member 222R.

When the branch shaft member 220 (the left branch shaft member 220L and the right branch shaft member 220R) is composed of two members (the first left branch shaft member and the second branch shaft member), the state shown in FIG. The left branch shaft member 220 can be folded.

FIG. 9 is a step diagram showing changes until the tension-type roof 100 in which the branch shaft member 220 is composed of two members is folded. The procedure for folding the tension roof 100 will be described below with reference to this figure.

First, in the state shown in FIG. 9(a), the left expansion/contraction means 600L and the right expansion/contraction means 600R are expanded. The members 220R (the first right branch shaft member 221R and the second right branch shaft member 222R) are each raised to a position close to horizontal, that is, the left branch shaft member 220L and the right branch shaft member 220R are in an unfolded state. . When the left elastic means 600L and the right elastic means 600R contract from this state, the left branch shaft member 220L rotates downward counterclockwise around the inner end, as shown in FIG. 9(b). The branch shaft member 220R rotates downward clockwise around the inner end, and the left branch shaft member 220L and the right branch shaft member 220R hang slightly downward. In the state shown in FIG. 9B, the first left branch shaft member 221L and the first right branch shaft member 221R are in contact with the rotation control member 730, respectively.

Then, when the left elastic means 600L and the right elastic means 600R are further contracted from the state shown in FIG. The second right branch shaft member 222R rotates clockwise around the inner end (joint end with the first right branch shaft member 221R). downwards. As a result, the second left branch shaft member 222L is folded so that the first left branch shaft member 221L and the second left branch shaft member 222L form a "sideways (rotated clockwise in the drawing) V-shape". The second right branch shaft member 222R is folded so that the first right branch shaft member 221R and the second right branch shaft member 222R form a "sideways (counterclockwise in the figure) V-shape". At this time, due to the effect of installing the rotation control member 730, the first left branch shaft member 221L and the first right branch shaft member 221R are maintained in the state shown in FIG. The downward rotation of the right branch shaft 221R is controlled, so that only the second left branch shaft 222L and only the second right branch shaft 222R rotate downward.

On the other hand, when the left elastic means 600L and the right elastic means 600R are extended from the state shown in FIG. Only the branch shaft member 222R rotates upward counterclockwise around the inner end, and as shown in FIG. The branch shaft member 221R and the second right branch shaft member 222R are generally linearly arranged.

When the left elastic means 600L and the right elastic means 600R are further extended from the state shown in FIG. , and the right branch shaft member 220R (the first right branch shaft member 221R and the second right branch shaft member 222R) rotates upward counterclockwise around the inner end. As a result, as shown in FIG. 9(a), the left branch shaft 220L and the right branch shaft 220R rise to a position close to the horizontal, that is, the left branch shaft 220L and the right branch shaft 220R are in an unfolded state. . At this time, if the connecting rope member 710 and the opening control member 720 are installed, the first left branch shaft member 221L and the first right branch shaft member 221R will move from the state in which the connecting rope member 710 is in contact with the opening control member 720. As described above, upward rotation is impossible, that is, upward rotation of the first left branch shaft member 221L and the first right branch shaft member 221R is controlled. As a result, only the second left branch shaft member 222L rotates upward, and only the second right branch shaft member 222R rotates upward. The member 221R and the second right branch shaft member 222R are arranged in an extremely straight line.

As described above, the upward rotation of the first left branch shaft member 221L and the first right branch shaft member 221R is controlled by the contact of the connecting rope member 710 with the opening control member 720 . In other words, the limit of upward rotation of the first left branch shaft member 221L and the first right branch shaft member 221R depends on the installation position (installation height) of the opening control member 720 . Therefore, as shown in FIG. 10, if the opening control member 720 has a structure in which the installation height can be changed, the upward rotation of the first left branch shaft member 221L and the first right branch shaft member 221R can be restricted at a desired position. It is suitable for For the sake of convenience, FIG. 10 shows only the right branch shaft member 220R (the first right branch shaft member 221R and the second right branch shaft member 222R), and the left branch shaft member 220L (the first left branch shaft member 221L and the second left branch shaft member 220L). 222L) are omitted. For example, in FIG. 10(a), since the opening control member 720 is arranged at a low position, the left branch shaft member 220L and the right branch shaft member 220R stop in a state inclined below the horizontal. On the other hand, in FIG. 10(b), since the opening control member 720 is arranged at a high position, the left branch shaft member 220L and the right branch shaft member 220R are deployed in a state inclined upward from the horizontal.

By the way, FIG. 7 shows an example in which the left auxiliary arm 602L and the right auxiliary arm 602R are provided. 11A and 11B are diagrams schematically showing the tensioned roof 100 provided with the left access control member 800L and the right access control member 800R, where (a) is a cross-sectional view taken along a vertical plane, and (b) is a left access control. FIG. 10 is a partially enlarged plan view of a joint portion of two members (a first left branch shaft member and a second branch shaft member) when a member 800L and a right approach control member 800R are provided; For the sake of convenience, FIG. 11A shows only the right branch shaft member 220R (the first right branch shaft member 221R and the second right branch shaft member 222R), and the left branch shaft member 220L (the first left branch shaft member 221L and the second right branch shaft member 222R). The left branch shaft member 222L) is omitted.

The functions of the left access control member 800L and the right access control member 800R will be described below with reference to FIG. Since the left access control member 800L also has the same function, the right access control member 800R will be described here as an example. As shown in FIG. 11(a), the right access control member 800R is arranged so as to be sandwiched between the right elastic means 600R and the second right branch shaft member 222R. 222R. As can be seen from this figure, by interposing the right access control member 800R between the right elastic means 600R and the second right branch shaft member 222R, when the right elastic means 600R is expanded, the right elastic means 600R and the second right branch shaft member 222R The approach to the right branch shaft member 222R is controlled, that is, the upward rotation of the right telescopic means 600R is restricted, and as a result, the upward rotation of the second right branch shaft member 222R is also restricted. Therefore, by appropriately designing the dimensions of the right access control member 800R, it is possible to arbitrarily set the upper limit of the upward rotation of the second right branch shaft member 222R.

Here, with reference to FIG. 11(b), an example of a joint structure between the first right branch shaft member 221R and the second right branch shaft member 222R will be described in detail. Since the first left branch shaft member 221L and the second left branch shaft member 222L also have the same joint structure, the first right branch shaft member 221R and the second right branch shaft member 222R will be explained here as an example. In the example of this figure, a first right joint plate 223R and a second right joint plate 224R are provided, and these first right joint plate 223R and second right joint plate 224R are rotatably joined by a right hinge 225R. The outer end of the first right branch shaft member 221R is fixed to the first right joint plate 223R, and the inner end of the second right branch shaft member 222R is fixed to the second right joint plate 224R. The first right branch shaft member 221R and the second right branch shaft member 222R are rotatably coupled. Also, the right locking tool 601R is pin-connected to the second right joint plate 224R, whereby the right locking tool 601R and the second right branch shaft member 222R are rotatably connected. The right access control member 800R is arranged so as to be sandwiched between the right locking member 601R and the second right joint plate 224R, and then attached to the right elastic means 600R (or the second right joint plate 224R). ing.
