  This was realized by configuring as illustrated in the drawings and described in the examples.

  Next, a preferred embodiment of the present invention will be described with reference to the drawings. In the figure, reference numerals 1, 1a, 1b, and 1c denote pillars standing at four corners of a quadrangle (square), and each of the pillars 1, 1a, 1b, and 1c has an anchor. Top joints J3, J5, J7, J1 are attached to the tops of the columns 1, 1a, 1b, 1c. The support joints J4 are spaced apart from the top joints J3, J5, J7, J1. , J6, J8, J2 are attached. A crossbar 6 is provided between the top joints of adjacent struts, for example between J3 and J5, via a pivot joint 2 and between the support joints J4 and J6 via a pivot joint b. A cross bar 7 for projecting the pivot joint b upward is provided, and at the time of assembly, the pivot joint b becomes a straight line connecting the top joints J3 and J5. This positional relationship is the same even in the pivot joints c, d, a in the respective cross bars 7a, 7b, 7c.

  Further, in the figure, reference numeral 10 denotes a central support member of the awning, and this central support member 10 is supported in a hollow manner by support rods 11, 11a, 11b, and 11c having respective base joints J3, J5, J7, and J1 as base ends. Yes.

  In this embodiment, reinforcing girder rails 12, 12a, 12b, 12c are installed between adjacent top joints J3, J5, J5, J7, J7, J1, J1, and J3. 12, 12a, 12b, and 12c are configured to be integrally fixed with the pivot joints b, c, d, and a at their intermediate positions. Here, the structure of the girder rails 12... 12 c can use either a half-size two-piece or one-piece long material.

  Further, in FIG. 2, reference numeral 13 denotes a central pillar for supporting the center of the awning. This central pillar is provided with a receiving member at the lower end, and a movable joint is provided slightly above the receiving member. Support rods 14, 14a, 14b, 14c from the pivot joints b, c, d, a are connected to the receiving member, and support rods 15, 15a from the pivot joints 2, 3, 4, 5 to the movable joint. , 15b, 15c are connected in a hollow manner. Also in this example, the girder rails 12, 12a, 12b, and 12c are installed between the adjacent top joints in the same manner as in FIG.

  The example shown in FIG. 3 has a structure in which the frame structure shown in FIG. 2 is continuous, and the number of support posts and the number of central pillars of the awning increase. However, the support pillars 14, 15. In addition, the support rod 11 shown in FIG. 1 is also used at the same time, and the girder rail between the top joints J5 and J7 is used between the top joints of the increased struts. In the installed direction, the number of pivot joints, which will be continued as the girder rails are increased, will also increase as the crossbar increases.

  Here, assuming that the girder rail 12c is provided between the top joints J1 and J3, since the members constituting the crossbar 7c are connected by the pivot joint a (pin), the members are slightly separated from each other. To be polymerized. Accordingly, as shown in FIG. 4, the constituent members of the cross bar 7c are provided at the end joints J1 and J3, and are sandwiched between brackets B1 and B3 that are formed to face each other with their overlapping dimensions shifted from each other. The end portions of the girder rails 12c disposed outside the brackets B1 and B3 are passed through the brackets B1 and B3, and are fixed integrally with components of the crossbar 7c with components such as bolts and screws. The part of the pivot joint a is also integrated by bolts, screws, etc. through the connecting member a1 of the beam rail 7c.

  Moreover, the girder rails 12, 12a, etc. can be used as curtain rails as needed, and can cover the side surfaces of the assembled frame. The girder rails 7 can be of various shapes such as a square pipe with a bottom open, a cylinder (cylinder), a prism (square cylinder), and the like.

  In addition to the configuration shown in FIG. 5, the connection between the girder rail 12c and the top joints J3 and J1 is as shown in FIG. 6, with a protrusion 12T provided below the end of the girder rail 7c below the side of the bracket B1. It can also be configured to fit into the socket S1 provided in the direction or to insert the protrusion T provided in the axial direction at the end of the girder rail 12c into the socket S2 provided in parallel with the bracket B1.

  Further, the girder rails 12c... Can be mounted as shown in FIGS. This configuration is the simplest and practical in terms of time for installation. That is, the length of the girder rail 12c is made equal to the length of the crossbar 7c, and is divided into two parts, one end of which is pivotally supported by the pivot joint a and the other end is temporarily fixed to the support joint J2. is there. When the frame structure is folded, the pivot joint a is raised by the movement of the cross bar 7c, while the support joint J2 is lowered along the column 1c.

  When the cross bar 7c is expanded from this folded state, the pivot joint a is lowered and the support joint J2 is raised and set as a framework. Here, as shown in FIG. 9, an insertion rod 12c1 for adjusting the length is inserted into the end of the girder rail 12c, and this insertion rod 12c1 protrudes when parallel to the constituent members of the crossbar 7c. Then, it is temporarily fixed to the support joint J2, but when assembling the frame, the insertion rod 12c1 is retracted and connected to the top joint J1 with the length shortened. In this configuration, as described above, the bracket B1 is not penetrated and stopped by a bolt or the like, and the fixing is made differently from the cross bar 7c.

  The top joint J1 in this case is configured as shown in FIG. A bracket B1 corresponding to the cross bar 7c and a bracket B2 corresponding to the cross bar 7b are formed at right angles, and the projection connecting portions B which receive the insertion rods 12c1, 12b1 of the girder rails 12c, 12b outside the brackets B1, B2 , I have formed. The relationship between the projection connecting portions b, i and the insertion rods 12c1, 12b1 is a structure in which either side is inserted and the inserted state is fixed by a pin or the like. The bracket B4 in the figure is for supporting the end of the support rod 11c.

  Further, the framework structure according to the present invention can be configured as shown in FIGS. In this case, the columns 1 to 1c are arranged in a rectangle, and the ratio of the long side to the short side is set to 3: 2, which is different from the case of 2: 1 shown in FIG. That is, in this example, the relationship between the crossbars on the short side, for example, 6c, 7c and the girder rail 12c, is the same as that in the case where the above-mentioned support pillars are squarely arranged. In addition to 7, 6d and 7d having substantially half dimensions are added, and pivot joints 2a and e are added.

  In this embodiment, another central pillar 13 is added for stability. The crossbar 6 is connected to the end of the crossbar 7d at the pivot joint e, and the crossbar 7 is connected to the end of the crossbar 6d at the pivot joint 2a. In the four pivot joints b, 2, e, and 2a, the coding type is expanded and contracted.

  Here, the girder rails 12 and 12b are installed between the top joints J3, J5, J7, and J1, but the girder rails 12 and 12b are not formed as a single body, but approximately one third. As a preferable means, the method shown and described in FIGS. 8 to 10 is used between the top joints J3 and b and between J5 and e. Also, between b and e, applying this method, one end of the girder rail is fixed to the pivot joint b or e, and when fixed to b, the other end is temporarily fixed to 2a and fixed to e. In this case, it is temporarily fixed to 2, and when the framework is expanded, the temporary fixing is removed and fixed to e or b manually.

  By adopting such a configuration, even when the girder rails 12 and 12b are used as curtain rails, the runners can run smoothly, and there is no possibility of catching or stopping on the way.

  The framework structure of the tent according to the present embodiment is configured as described above. Several connections between the top joints J1 and the girder rails 12c have been shown, but it is also possible to use U-bolts in addition to these, and various configurations are effective as long as they meet the purpose.
