Description

[Technical field]

[0001] An embodiment of the present invention relates to a signboard. [Background technology]

[0002] In civil engineering and construction projects, etc., it is often required by law, ordinance, safety regulations, etc. to install construction signboards so that the outline of the project can be recognized. These construction signboards contain a lot of information, such as the name of the project, the purpose of the project, information about the contractor (such as the contractor's name and contact information), safety precautions, and the expected construction period, so they tend to be large signboards.

[0003] Conventionally, in order to store such large signboards compactly, it has been common to disassemble the frame and the display panel for transport. The support legs of the frame are foldable, so when transporting the signboard, the support legs are folded together with the frame, and when setting up the signboard, the support legs are spread apart from the frame to form four legs with the frame and support legs.

[0004] However, when folded, it becomes long vertically, making it difficult to carry and requiring a certain amount of vertical space to store. In addition, screws are required to attach the display board to the frame, and removing the board also requires the time and effort of removing the screws.

[0005] Patent Document 1 describes an advertising display (standing signboard) that has a first part and a second part with legs on the left and right, which are rotatably joined at their upper sides and whose lower sides are spaced a specified distance apart so that the advertising display can stand on its own with four legs, and the legs have a leg main body and a male screw body that can increase or decrease the amount they protrude from within the leg main body, allowing the advertising display to be stably placed in a manner that will not cause it to fall over regardless of the characteristics of the placement location.

[0006] Patent Document 2 describes a foldable signboard in which the display section is divided into upper and lower parts and folded with the display surface facing inward, making it easy for workers to carry. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2019-120795 A [Patent Document 2] JP 2002-339324 A Summary of the Invention [Problem to be solved by the invention]

[0008] As mentioned above, when folded, the conventional technology is difficult to carry and store because it is long vertically. In addition, screws are required to attach the display board to the frame, and the screws must be removed when removing it, which is time-consuming. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, the standing signboard of the embodiment is a standing signboard that can stand on its own using the support legs by rotatably joining the upper sides of a first signboard frame and a second signboard frame, which have support legs on the lower side, and rotating the first signboard frame and the second signboard frame so that the support legs are separated by a predetermined distance, and is equipped with a folding joint that allows the first signboard frame and the second signboard frame to be folded at their vertical middle parts, an expansion and contraction connecting part that allows the first signboard frame and the second signboard frame to be contracted horizontally, a storage connecting part that allows the support legs to be expanded and contracted in the first signboard frame and the second signboard frame for storage, and upper and lower display parts that are divided by the vertical folding part of the first signboard frame and are each expandable and contractible in the horizontal direction.

[0011] Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. The signboard according to the embodiment will be described with reference to Figs. 1, 2, and 3, which show an elevational front view, an elevational side view, and an elevational back view, respectively. The terms "upper and lower" used in the description refer to the side where 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. Furthermore, the terms "left and right" refer to the left and right of 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 upward and the display panel portion of the signboard 10 is viewed from outside.

[0012] As shown in Figures 1 to 3, the signboard 10 of the embodiment is a signboard that can stand on its own by the support legs 16a, 16b when the first sign frame 11 and the second sign frame 12 are rotated so that the support legs 16a, 16b are spaced a predetermined distance apart, with the upper sides of the first sign frame 11 and the second sign frame 12 being rotatably joined to each other via a pivot joint 19.

[0013] In this type of standing sign 10, folding joints 13a, 13b are provided that enable the first sign frame 11 and the second sign frame 12 to be folded at their vertical intermediate portions (folding portions), respectively. The standing sign 10 also has telescopic connectors 14a, 14b that enable the first sign frame 11 and the second sign frame 12 to be contracted in the left-right direction, i.e., the horizontal direction, respectively. Furthermore, the standing sign 10 has storage connectors 15a, 15b that enable the support legs 16a, 16b to be telescopically stored in the first sign frame 11 and the second sign frame 12, respectively. Details will be described below.

[0014] The first signboard frame 11 is a frame for fixing the upper display section 17a and the lower display section 17b, on which the content to be displayed on the signboard is written. Furthermore, the first signboard frame 11 is provided with a support leg 16a, which is provided to make the standing signboard 10 stand on its own.

[0015] The second sign frame 12 is rotatably joined to the first sign frame 11 via a pivot joint 19. Like the first sign frame 11, it is provided with support legs 16b to allow the standing sign 10 to stand on its own. When the first sign frame 11 and the second sign frame 12 are rotated so that the support legs 16a and 16b are spaced a predetermined distance apart, the standing sign 10 becomes able to stand on its own, supported by the support legs 16a and 16b.

[0016] In the embodiment, the second sign frame does not have 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 manner 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 up and down, i.e., at the middle in the vertical direction. The folding joints 13a and 13b need to be attached to the outside of the front 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 outward, respectively. In the embodiment, the folding joints 13a and 13b are hinges, but are not limited thereto and may be any joint having the above-mentioned function.

[0018] Furthermore, fasteners 27a, 27b are provided on the back side of the folding joints 13a, 13b. The fastener 27a in the first sign frame 11 will be described with reference to Fig. 6. Note that the fastener 27b in the second sign frame has the same configuration as the fastener 27a in the first sign frame 11, and therefore will not be described.

[0019] The fastener 27a is provided on the first sign frame 11 and is located behind the folding joint 13a, which is a hinge. Since the folding joint 13a rotates freely, it is difficult to hold the first sign frame 11 in a usable state (unfolded state) without the fastener 27a. In the embodiment, the fastener 27a is a fastener, which is a so-called snap lock. The fastener 27a is not limited to a fastener, and may be any fastener that can hold the first sign frame 11 in an unfolded state.

[0020] The telescopic connectors 14a and 14b are connectors that enable the first sign frame 11 and the second sign frame 12 to be contracted in the left-right direction, i.e., the horizontal direction. The telescopic connector 14a in the first sign frame 11 will be described with reference to Fig. 4. Note that the telescopic connector 14b in the second sign frame has the same configuration as the telescopic connector 14a in the first sign frame 11, and therefore will not be described here.

[0021] As shown in FIG. 4, the telescopic connecting portion 14a is divided into an inserting portion 21 and a storage portion 22, and the inserting portion 21 is made smaller than the storage portion 22 so that it can be slid and inserted into the storage portion 22. The inserting portion 21 is inserted into the storage portion 22, and is integrated with the storage portion 22 by a fitting structure, and the stopper 23 is fitted into the stopper hole 24a and fixed. The stopper 23 has an elastic force that is embedded in the first sign frame when pressed with a finger, and when the stopper 23 is pressed with a finger from the fixed state, the inserting portion 21 becomes slidable in the storage portion 22, and the stopper 23 slides until it fits into the stopper hole 24b, and the first sign frame 11 can be contracted in the left-right direction. In addition, the telescopic connecting portions 14a and 14b are not limited to the configuration of the embodiment, and other configurations may be used as long as they have the above-mentioned functions.

[0022] The storage connectors 15a and 15b are operating levers for enabling the support legs 16a and 16b to be stored in the first sign frame 11 and the second sign frame 12, respectively. The storage connector 15a in the first sign frame 11 will be described with reference to Fig. 5. Note that the storage connector 15b has the same configuration as the storage connector 15a, and therefore its description will be omitted.

[0023] For example, in the embodiment, as shown in Fig. 5, a plurality of fixing grooves 26a are provided on the inner side of the side surface of the support leg 16a, and the tip of the operation lever 25a engages with the fixing grooves 26a to fix the support leg 16a. When storing the support leg 16a in the first sign frame 11, the lever portion of the operation lever 25a is pulled up, the tip of the operation lever 25a is released from the groove, and the support leg 16a slides inside the first sign frame 11 and can be stored. In addition, the storage connectors 15a and 15b are not limited to the configuration in the embodiment, and may have other configurations as long as they have the above-mentioned functions.

[0024] The upper display section 17a and the lower display section 17b will be described with reference to Figs. 1 and 6. The upper display section 17a and the lower display section 17b are display sections that display information related to the construction such as the construction content, period, and contractor. The upper display section 17a is provided at the upper level of the first sign frame 11, and the lower display section 17b is provided at the lower level of the first sign frame 11 so as to divide the first sign frame 11. Since the first sign frame 11 and the second sign frame 12 can be contracted in the left-right direction by the expansion and contraction connecting sections 14a and 14b, the upper display section 17a and the lower display section 17b are expandable in a roll shape in the embodiment. Other expandable configurations such as bellows type may also be used.

[0025] The upper display unit 17a and the lower display unit 17b have a winding mechanism using a spring like a roll screen, and are provided with gripping parts 29a and 29b, respectively, and by gripping the gripping parts 29a and 29b, it is possible to stretch the rolled upper display unit 17a and the lower display unit 17b against the winding force described above. Furthermore, the tips of the gripping parts 29a and 29b are ring-shaped, and by hooking and locking the ring parts on the locking parts 28a and 28b, it is possible to hold the upper display unit 17a and the lower display unit 17b in a stretched state. The material of the upper display unit 17a and the lower display unit 17b is preferably a vinyl-based material that is excellent in durability and weather resistance, such as tarpaulin.

[0026] Additionally, the upper display section 17a and the lower display section 17b are provided with a storage pocket 31. The contents of the construction can be recognized by storing paper, pouches, etc., which are display materials indicating the construction details to be displayed on the signboard 10, in the storage pocket 31. By switching the stored contents, the signboard 10 can be reused for different construction works, eliminating the need to make a new signboard for each construction work. The storage pocket 31 is transparent and preferably made of a water-resistant material such as vinyl or silicone.

[0027] Next, a method for folding the signboard 10 will be described in the following <Step 1> to <Step 5> with reference to Figs. 4 and 7 to 12.

[0028] <Step 1> First, as shown in FIG. 7, the loop portions of the gripping portions 29a, 29b are removed from the locking portions 28a, 28b, and the upper display portion 17a and the lower display portion 17b are stored in a roll shape.

[0029] <Step 2> Next, as shown in FIG. 8, the pivot joint 19 is pivoted so that the first sign frame 11 and the second sign frame 12 approach each other, and the standing sign 10 is folded.

[0030] <Step 3> 5 and 9, the operating lever 25a is operated to store the support leg 16a in the first sign frame 11. Similarly, for the second sign frame 12 (not shown), the operating lever 25b is operated to store the support leg 16b in the second sign frame 12.

[0031] <Step 4> After the support legs 16a, 16b have been retracted, the state is as shown in the left diagram of Fig. 10. Next, as shown in the right diagram of Fig. 10, the folding joints 13a, 13b are rotated to fold the first sign frame 11 and the second sign frame 12.

[0032] <Step 5> 4 and 11, the stopper 23 is pressed with a finger, and the insertion part 21 is slid into the storage part 22 until the stopper 23 fits into the stopper hole 24b, thereby contracting the first sign frame 11 in the left-right direction. Although not shown, the same is true for the second sign frame 12, and the second sign frame 12 can be contracted in the left-right direction.

[0033] As described above, by folding the signboard 10 according to the above-mentioned steps <Step 1> to <Step 5>, the signboard 10 can be transformed into a compact, easily portable state.

[0034] Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This novel embodiment can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and spirit of the invention, and are included in the invention and its equivalents described in the claims. [Explanation of symbols]
