Figures 1, 2, and 3 are, Elevation front view, elevation side view, elevation rear view of the signboard according to the embodiment That is the case. In the explanation, "up and down" refers to the side on which the support legs 16a and 16b are provided as the lower side of the first sign frame 11 and the second sign frame 12, and the opposite side as the upper side. "Left and right" refers to the left and right relative to the first sign frame 11 and the second sign frame 12 when the signboard 10 is installed with the upper sides of the first sign frame 11 and the second sign frame 12 facing upwards, and the display panel of the signboard 10 is viewed from the outside.

[0012] As shown in Figures 1 to 3, The standing signboard 10 according to the embodiment is under above the first signboard frame 11 and the second signboard frame 12 provided with support legs 16a and 16b on the sides 、 joined to each other rotatably via a rotation joint portion 19 Oki , and rotates the first signboard frame 11 and the second signboard frame 12 so that the support legs 16a and 16b are separated by a predetermined distance child and in , and is a standing signboard that can stand on its own by the support legs 16a and 16b.

[0013] In such a standing signboard 10, folding joint portions 13a and 13b are provided that enable the first signboard frame 11 and the second signboard frame 12 to be folded at intermediate portions (folding portions) in the vertical direction. Further, the standing signboard 10 includes telescopic connecting portions 14a and 14b that enable the first signboard frame 11 and the second signboard frame 12 to be respectively contracted in the left-right direction, that is, in the horizontal direction. Furthermore, the standing signboard 10 includes storage connecting portions 15a and 15b that enable the support legs 16a and 16b to be telescopically stored in the first signboard frame 11 and the second signboard frame 12 respectively. Details will be described below.

[0014] The first signboard frame 11 is provided with an upper display portion 17a and a lower display portion 17b on which the content displayed on the signboard is described, and is a frame for fixing these. Further, the first signboard frame 11 includes a support leg 16a, and the support leg 16a is provided for making the standing signboard 10 stand on its own.

[0015] The second signboard frame 12 is rotatably joined to the first signboard frame 11 via a rotation joint portion 19. Similar to the first signboard frame 11 、 it includes a support leg 16b for making the standing signboard 10 stand on its own. and,When the first sign frame 11 and the second sign frame 12 are rotated so that the support legs 16a and 16b are separated by a predetermined distance, the signboard 10 becomes self-supporting, supported by the support legs 16a and 16b.

[0016] In this embodiment, the second sign frame is not provided with an upper display section 17a and a lower display section 17b, but it is also possible to provide an upper display section 17a and a lower display section 17b in the same way as the first sign frame 11.

[0017] The folding joints 13a and 13b are so-called hinges that enable the first sign frame 11 and the second sign frame 12 to be folded in the vertical direction, that is, in the middle of the vertical direction. The folding joints 13a and 13b need to be attached to the front outer surfaces of the first sign frame 11 and the second sign frame 12 so that the first sign frame 11 and the second sign frame 12 can be folded outwards, respectively. Furthermore, although the folding joints 13a and 13b in this embodiment are hinges, they are not limited to hinges and any type of connector having the above-described function is acceptable.

[0018] Furthermore, fasteners 27a and 27b are provided on the back side of the folding joints 13a and 13b. Figure 6 is a rear view of the sign frame 11 in a signboard according to the embodiment. Using Figure 6, Regarding fastener 27a in the first sign frame 11 Theory To clarify, fastener 27b in the second sign frame. teeth, Since it has the same configuration as the fastener 27a in the first sign frame 11, the explanation is omitted.

[0019] Fastener 27a is 、 It is provided on the first sign frame 11 and is located on the back of the folding joint 13a, which is a hinge. 、Because it rotates freely, without the fastener 27a, it is difficult to hold the first sign frame 11 in a usable state (unfolded state). In this embodiment, the fastener 27a is a fastening device, which is what is commonly called a snap lock. In addition, The fastener 27a is not limited to a fastening metal fitting; any fastener that can hold the first sign frame 11 in an unfolded state is acceptable.

[0020] The expandable connecting parts 14a and 14b are 、 This is a connecting part that allows the first sign frame 11 and the second sign frame 12 to be retracted in the left-right direction, i.e., horizontally. Figure 4 is a detailed view of the retractable connecting section in the signboard according to the embodiment. Using Figure 4, Regarding the expandable connecting section 14a in the first sign frame 11 Theory To clarify, the telescopic connecting section 14b in the second sign frame has the same configuration as the telescopic connecting section 14a in the first sign frame 11, so its explanation will be omitted.

[0021] As shown in Figure 4, the telescopic connecting section 14a is divided into an insertion section 21 and a storage section 22. ru. soshi The insertion part 21 is made smaller than the storage part 22 so that it can slide into the storage part 22. The insertion part 21 is inserted into the storage part 22 and integrated with a fitting structure, and then the stopper 23 is fitted into the stopper hole 24a and fixed in place. The stopper 23 has enough elasticity to be embedded in the first sign frame when pressed with a finger, and when the stopper 23 is pressed with a finger from its fixed position, the insertion part 21 becomes slidable within the storage part 22. Yes, they are. The stopper 23 slides until it fits into the stopper hole 24b, allowing the first sign frame 11 to be shortened in the left-right direction. Furthermore, the expandable and retractable connecting parts 14a and 14b are not limited to the configuration of the embodiment, and other configurations are acceptable as long as they have the functions described above.

[0022] The storage connection sections 15a and 15b are operating levers that allow the support legs 16a and 16b to be stored in the first sign frame 11 and the second sign frame 12, respectively. Figure 5 is a detailed view of the storage connection section in the signboard according to the embodiment. Using Figure 5, Regarding the storage connection section 15a in the first sign frame 11 Theory To clarify, the storage connection section 15b teeth, Since it has the same configuration as the storage connection section 15a, the explanation will be omitted.

[0023] As shown in Figure 5, For example, in this embodiment, support Multiple fixing grooves 26a are provided on the inner side of the support leg 16a. ru. soshi The support leg 16a is fixed in place by the tip of the operating lever 25a engaging with the fixing groove 26a. When storing the support leg 16a in the first sign frame 11, the lever portion of the operating lever 25a is pulled upward, the tip of the operating lever 25a disengages from the groove, and the support leg 16a slides inward into the first sign frame 11 for storage. Furthermore, the storage connection sections 15a and 15b are not limited to the configuration of this embodiment, and other configurations are acceptable as long as they have the functions described above.

[0024] Using Figures 1 and 6, Regarding the upper display section 17a and the lower display section 17b Theory I will reveal it. The upper display section 17a and the lower display section 17b are display sections that display information related to the construction work, such as the details of the work, the period, and the contractor. The upper display section 17a is provided on the upper part of the first sign frame 11, and the lower display section 17b is provided on the lower part of the first sign frame 11, so as to divide the first sign frame 11. Because the first sign frame 11 and the second sign frame 12 can be shortened in the left-right direction by the telescopic connecting parts 14a and 14b, the upper display section 17a and the lower display section 17b are retractable in a roll-like manner in this embodiment. Other retractable configurations, such as a bellows type, may also be used.

[0025] The upper display section 17a and the lower display section 17b have a retractable mechanism using a spring, similar to a roller screen. .this Therefore, The upper display section 17a and the lower display section 17b are Each is provided with gripping parts 29a and 29b, and by gripping the gripping parts 29a and 29b, it becomes possible to extend the roll-shaped upper display section 17a and lower display section 17b in opposition to the winding force described above. Furthermore, the tips of the gripping parts 29a and 29b are ring-shaped, and by hooking the ring portion onto the locking parts 28a and 28b and locking them in place, it becomes possible to hold the upper display part 17a and the lower display part 17b in an extended state. The materials for the upper display section 17a and the lower display section 17b are preferably vinyl-based materials with excellent durability and weather resistance, such as tarpaulin.

[0026] Furthermore, the upper display section 17a and the lower display section 17b are 、 It is equipped with a storage pocket 31. By storing the paper, pouch, or other display material containing the details of the construction work to be displayed on the signboard 10 in the storage pocket 31, the details of the construction work can be easily identified. By changing the contents stored inside, the signboard 10 can be reused for different construction projects, eliminating the need to produce a new signboard for each project. In addition, The storage pocket 31 should be transparent and preferably made of a water-resistant material such as vinyl or silicone.

[0027] next, Using Figures 4, 7 to 12, Regarding the folding method of signboard 10, under This is explained in steps 1 through 5.
