[0004] To solve the above problems, the fence according to claim 1 includes a horizontal bar, a fitting, and a vertical bar. The horizontal bar is a profile having a groove that opens along the longitudinal direction, and the all circumference to hollow part Established is present. The fitting is Swallowed in the groove, and the vertical bar is inserted into the fitting and Rotatable axially supported by the fitting. [[ID=4This is a front view of the fence with the angles of the upper and lower horizontal bars adjusted. [Modes for carrying out the invention]
[0007] Hereinafter, an embodiment of fence A according to the present invention will be described with reference to the drawings. In the following explanation, the same symbols in different figures indicate parts with the same function, and redundant explanations in each figure will be omitted as appropriate.
[0008] [Basic Fence Configuration] As shown in Figure 1, Fence A consists of upper horizontal bars (horizontal bars) 2 and lower horizontal bars (horizontal bars) 3 installed between multiple support posts 1, with multiple vertical bars 4 attached between the upper horizontal bars 2 and the lower horizontal bars 3. As shown in Figure 3, support column 1 is a hollow tube. The upper crossbar 2 and the lower crossbar 3 are attached to the support column 1 via brackets 5 that are attached to the outer surface of the support column 1. The vertical crossbar 4 is attached across the upper bracket 6, which is inserted inside the upper horizontal crossbar 2, and the lower bracket 7, which is inserted inside the lower horizontal crossbar 3.
[0009] [Structure of the upper horizontal bar] As shown in Figure 2, the upper crossbar 2 is a rectangular profile with a roughly U-shaped cross section, having a downward-opening groove 20 along its longitudinal direction, and multiple hollow sections (three in the figure) 21, 22, and 23 are formed around the groove 20. The hollow section 21 is located at the top of the groove 20, the hollow section 22 is located to the left of the groove 20 in the figure, and the hollow section 23 is located to the right of the groove 20 in the figure, and is provided along the entire length of the upper crossbar 2. The hollow section 21 and the hollow sections 22 and 23 are separated vertically by ribs 24 that are provided along the entire lengthwise side of the upper crossbar 2. Rib 24 is located approximately in the center of the upper crossbar 2 in the vertical direction. This upper crossbar 2 is pivotally supported on the bracket 5 at the positions of the hollow sections 22 and 23.
[0010] [Structure of the lower horizontal bar] As shown in Figure 2, the lower crossbar 3 has the same configuration as the upper crossbar 2 but is inverted vertically. It is a rectangular cross-section with a roughly U-shaped profile and has a groove 30 that opens upward along the longitudinal direction. Multiple hollow sections (three in the figure) 31, 32, and 33 are formed around the groove 30. The hollow section 31 is located below the groove 30, the hollow section 32 is located to the left of the groove 30 in the illustration, and the hollow section 33 is located to the right of the groove 30 in the illustration, and is provided over the entire length of the lower crossbar 3. The hollow section 31 and the hollow sections 32 and 33 are separated vertically by a rib 34 that is provided along the entire lengthwise side of the lower crossbar 3. Rib 34 is located approximately in the center of the lower crossbar 3 in the vertical direction. This lower crossbar 3 is pivotally supported on the bracket 5 at the positions of the hollow sections 32 and 33.
[0011] [Structure of the upper attachment] As shown in Figure 2, the upper bracket 6 is a rectangular profile with a roughly U-shaped cross-section, having a groove 60 with a downward opening along its longitudinal direction, and is inserted into the groove 20 of the upper crossbar 2 and held within the groove 20. The depth of the groove 60 of the upper bracket 6 is approximately the same as the vertical height of the hollow sections 22 and 23, and when the vertical bar 4 is inserted into the groove 60, it can be pivotally supported in a position facing the hollow sections 22 and 23. Such an upper attachment 6 is incorporated into the upper crossbar 2 by inserting it into the groove 20 from the end of the upper crossbar 2.
[0012] [Composition of the lower attachment] As shown in Figure 2, the lower bracket 7 has the same configuration as the upper bracket 6 but is inverted vertically. It is a rectangular, roughly U-shaped profile with an upward-facing groove 70 along its longitudinal direction, and is inserted into the groove 30 of the lower crossbar 3 and held within the groove 30. The depth of the groove 70 of the lower bracket 7 is approximately the same as the vertical height of the hollow sections 32 and 33, and when the vertical bar 4 is inserted into the groove 70, it can be pivotally supported at a position facing the hollow sections 32 and 33. Such a lower attachment 7 is incorporated into the lower crossbar 3 by being inserted into the groove 30 from the end of the lower crossbar 3.
[0013] The upper horizontal beam 2 and the lower horizontal beam 3 with such a structure are reinforced by ribs 24 and 34. By this reinforcement, the pitch between the columns 1 can be increased. Furthermore, due to the plurality of hollow portions 31, 32, and 33 around the groove 30 provided by the ribs 24 and 34, the strength of the upper horizontal beam 2 and the lower horizontal beam 3 is increased, so that the pitch between the columns 1 can be increased. In this embodiment, as an example, a structure in which three hollow portions 21 to 23 and 31 to 33 are provided by partitioning with ribs 24 and 34 is illustrated, but the number of hollow portions may be two or four or more (not shown). Also, a structure may be adopted in which there are no ribs 24 and 34 and one hollow portion (not shown) is provided around the grooves 20 and 30 (not shown).
[0014] [Structure of the vertical beam] As shown in FIGS. 1 and 2, the vertical beam 4 is attached across the upper fitting 6 and the lower fitting 7. The upper end portion 40 is inserted into the upper fitting 6 built in the upper horizontal beam 2 and pivotally supported, and the lower end portion 41 is inserted into the lower fitting 7 built in the lower horizontal beam 3 and pivotally supported. The pivotal support position of the vertical beam 4 is set at the same height as the pivotal support positions of the upper horizontal beam 2 and the lower horizontal beam 3 at the bracket 5. The vertical beam 4 is pivotally supported so as to be rotatable with respect to the upper fitting 6 and the lower fitting 7, and constitutes a link mechanism with the upper horizontal beam 2 and the lower horizontal beam. That is, as shown in FIG. 4, when finely adjusting the angle between the upper horizontal beam 2 and the lower horizontal beam 3 from the horizontal state to the inclined state, the vertical beam 4 rotates corresponding to the longitudinal displacement of the upper horizontal beam 2 and the lower horizontal beam 3, so that the vertical beam 4 can be made vertical.
[0015] [Structure of the bracket] As shown in FIG. 3, the bracket 5 is formed in a substantially U-shape in plan view. The upper horizontal beam 2 and the lower horizontal beam 3 are inserted from the opening 50 side and pivotally supported inside, and the closed portion 51 side formed in an arc shape corresponding to the arc around the column 1 is fixed to the column 1. Bracket 5 has an elongated hole 52 along the circumferential direction of the arc of the closing portion 51, and even when the bolt 53 that passes through the elongated hole 52 and is screwed into the support column 1 is in a fixed position, bracket 5 can be slid along the circumference of the support column 1 by the distance of the elongated hole 52. In other words, it is not necessary to provide bolt holes in the support column 1 to match the slid bracket 5. Furthermore, a sloping portion 54 is provided at the corner of the closing portion 51 side of the bracket 5. When two brackets 5 are attached to a single support post 1 to form a fence A with a corner, the sloping portions 54 of the two brackets 5 face each other, allowing adjacent brackets 5 to be brought closer together.
[0016] In this case, it is preferable that the aforementioned upper crossbar 2, lower crossbar 3, vertical bar 4, upper bracket 6, and lower bracket 7 be assembled in advance at the factory to form a single unit. By using this type of unit, the construction of Fence A on site can be carried out efficiently.
[0017] As mentioned above, Fence A, with the above configuration, offers high construction efficiency, and furthermore, it can be constructed in a way that ensures strength even with long spacing between posts.
[0018] Although the fence A according to the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes, etc., that do not depart from the spirit of the present invention are also included.
[0019] Furthermore, the aforementioned embodiments can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose, configuration, etc. [Explanation of symbols]
