[Figure 8] It is a diagram showing a usage state of the upright member for access restriction and the erection member for access restriction according to the second embodiment. Modes for Carrying Out the Invention

[0011] The present disclosure provides an access restriction upright member X, and an access restriction spanning member Y used together with the access restriction upright member X. The access restriction upright member X and the access restriction spanning member Y are provided by way of example to illustrate the technical idea of the present invention, and do not limit the scope of the technical idea of the present invention. In addition, the constituent elements of the access restriction upright member X and the access restriction spanning member Y, and the material, shape, dimensions, number, arrangement, and the like of the constituent elements may be modified within the scope of the technical idea of the present invention.

[0012] The access restriction upright member X and the access restriction spanning member Y are members that demarcate areas where access should be restricted at construction sites, parking lots, and the like. Examples of the access restriction upright member X include access restriction cones, access restriction poles, and the like. Examples of the access restriction spanning member Y include access restriction cone bars, access restriction chains, access restriction ropes, access restriction belts, and the like.

[0013] The access restriction upright member X includes an upright portion 1 which is a main body to be erected.

[0014] The upright portion 1 is formed in a shape extending at least in the height direction. When the access restriction upright member X is an access restriction cone, the upright portion 1 is formed in a conical shape. When the access restriction upright member X is an access restriction pole, the upright portion 1 is formed in a columnar shape. The presence or absence of chamfering or corner rounding is optional.

[0015] The dimensions and color of the upright portion 1 are designed based on visibility suitable for access restriction. As for the dimensions, a height of about 300 to 1500 mm and a bottom surface of about 150 to 750 mm square are common. As for the color, white and warm colors (red, yellow, orange, etc.) are common.

[0016] The upright portion 1 is preferably configured to have predetermined rigidity and elasticity. In particular, the upright portion 1 is preferably made of plastic, rubber, or the like as a material, and is configured to be solid or hollow with a substantially smooth wall surface.

[0017] The access restriction erection member X includes a support part 2 that supports the erection part 1 from below.

[0018] The support portion 2 is provided so as to be connected to the lower end of the upright portion 1. The support portion 2 may be formed integrally with the upright portion 1, or it may be formed separately from the upright portion 1 and configured to be detachably attached to the upright portion 1.

[0019] The support portion 2 is formed in a shape that extends at least horizontally (e.g., a platform or plate). The shape of the support portion 2 in plan view can be any shape, such as a circle, ellipse, triangle (e.g., equilateral triangle), or quadrilateral (e.g., rectangle or square). The presence or absence of chamfers or rounded edges is also optional.

[0020] The access restriction erection member X is equipped with a mounting portion 3 to which the access restriction erection member Y can be attached. The mounting portion 3 is provided on the erection portion 1.

[0021] The mounting section 3 takes a suitable form based on the combination of the access restriction erection member X and the access restriction erection member Y. When the access restriction erection member X is an access restriction cone and the access restriction erection member Y is an access restriction cone bar, the mounting section 3 is configured as the top of the erection section 1, thereby holding the access restriction erection member Y. When the access restriction erection member X is an access restriction pole and the access restriction erection member Y is an access restriction chain or access restriction rope, the mounting section 3 is configured as a hook (open hook, ring hook, etc.) to which the access restriction erection member Y can be attached.

[0022] The access restriction erection member Y is configured to be able to be erected on multiple (especially two) access restriction erection members X. Preferably, the access restriction erection member Y is configured to be able to be erected linearly from the mounting portion 3 of one access restriction erection member X to the mounting portion 3 of the other access restriction erection member X in a plan view.

[0023] As shown in Figures 1 and 2, the access restriction erection member X and the access restriction erection member Y define a boundary area that demarcates the area where access should be restricted when in use. Here, it is considered that there are two such boundary areas: the erection member boundary area s1 defined by the access restriction erection member Y (or the mounting part 3 of the access restriction erection member X), and the erection member boundary area s2 defined by the support part 2 of the access restriction erection member X.

[0024] The erection member section screen s1 is defined as a vertical plane along the access restriction erection member Y (or the attachment point 3 of each access restriction erection member X).

[0025] The erection member area screen s2 is defined as a vertical plane that is in common contact with the support portion 2 of each entry restriction erection member X. In this case, the erection member area screen s2 is in contact with the convex hull t of the support portion 2 of the entry restriction erection member X in a planar projection view. Here, the convex hull t of the support portion 2 of the entry restriction erection member X is the smallest convex figure that encloses the support portion 2 of the entry restriction erection member X in a planar projection view (the figure formed by a rubber band when it is placed over it). Note that if the shape of the support portion 2 of the entry restriction erection member X in a planar projection view is a convex figure, the convex hull t coincides with that convex figure.

[0026] Normally, a predetermined misalignment occurs between the erection member section screen s1 and the upright member section screen s2, resulting in an area in the gap between the erection member section screen s1 and the upright member section screen s2 where the presence or absence of regulations is unclear.

[0027] Accordingly, in the access control erection member X provided in this disclosure, the erection portion 1 is configured such that, in a planar projection view, the mounting portion 3 is located on or near the edge of the convex hull t of the support portion 2.

[0028] This configuration mitigates or eliminates a predetermined misalignment between the erection member section screen s1 and the upright member section screen s2, thereby mitigating or eliminating the area in the gap between the erection member section screen s1 and the upright member section screen s2 where the presence or absence of restrictions is unclear. As a result, the regulator (e.g., road construction company) can secure the work area, which is the area to be restricted, to the maximum extent possible, and the restricted party (e.g., road users) can reliably prevent entry into the hazardous area, which is the area to be restricted.

[0029] Hereinafter, this disclosure provides two embodiments of the access restriction erection member X and access restriction erection member Y.

[0030] <First Embodiment> In the first embodiment, the entry restriction erection member X is an entry restriction cone X1, and the entry restriction erection member Y is an entry restriction cone bar Y1 that can be attached to the entry restriction cone.

[0031] <<Structure>> As shown in Figure 3, the upright section 1 is formed in the shape of an oblique cone, and more specifically, in the shape of an oblique cone. The upright section 1 is formed such that the angle between the generatrix and the base is not constant, and in particular, it is formed to include a generatrix that forms approximately a right angle with the base. In the plan view of the access restriction upright member X in Figure 3, the contour lines of the upright section 1 are shown as thin solid lines.

[0032] The support portion 2 is formed in the shape of a plate that is large enough to cover the bottom surface of the upright portion 1, and is particularly formed in the shape of a square plate. The support portion 2 is formed integrally with the upright portion 1.

[0033] The mounting portion 3 is configured as the top of the erecting portion 1.

[0034] Based on the above configuration, the erecting portion 1 is configured such that, in a plan view, the mounting portion 3 is located on or near the edge of the convex hull t of the support portion 2 (particularly near the inner edge of the convex hull t of the support portion 2), and in particular, the mounting portion 3 is located on or near the edge of the support portion 2 (particularly near the inner edge of the edge of the support portion 2).

[0035] As shown in Figure 4, in a modified configuration, it is also preferable that the erected portion 1 is configured such that, in a plan view, the mounting portion 3 is located on or near the corner of the support portion 2 (particularly near the inside of the corner of the support portion 2). In the plan view of the access restriction erected member X in Figure 4, the contour lines of the erected portion 1 are shown as thin solid lines.

[0036] As shown in Figure 5, the access control cone bar Y1 comprises a bar body 4 and mounting rings 5 ​​provided at both ends of the bar body 4.

[0037] The bar body 4 is formed in a rod shape, and in particular, in a straight rod shape.

[0038] The mounting ring 5 is formed in an annular shape, and in particular, in a circular shape. The mounting ring 5 may be formed integrally with the bar body 4, or it may be formed separately from the bar body 4 and configured to be detachably attached to the bar body 4.

[0039] The access control erection member Y defines the erection member section screen s1, and it is thought that such section screens include the bar section screen s11 defined by the bar body 4 and the ring section screen s12 defined by the mounting ring 5.

[0040] The bar section screen s11 is defined as a vertical plane along the bar body 4.

[0041] The ring section screen s12 is defined as a vertical surface that is in common contact with each of the mounting rings 5.

[0042] Typically, the bar body 4 is formed with a width smaller than the diameter of the mounting ring 5 and is positioned on a straight line connecting the centers of each mounting ring 5. As a result, a predetermined misalignment occurs between the bar section screen s11 and the ring section screen s12, creating an area in the gap between the bar section screen s11 and the ring section screen s12 where the presence or absence of restrictions is unclear.

[0043] Accordingly, in the entry restriction cone bar Y1 according to the first embodiment, it is preferable that the bar body 4 is formed with a width smaller than the diameter of the mounting ring 5 and is positioned on the common tangent of each mounting ring 5.

[0044] This configuration mitigates or eliminates a predetermined misalignment between the bar area screen s11 and the ring area screen s12, thereby mitigating or eliminating the area in the gap between the bar area screen s11 and the ring area screen s12 where the presence or absence of restrictions is unclear. As a result, regulators (e.g., road construction companies) can maximize the work area, which is the area to be restricted, and those being restricted (e.g., road users) can reliably prevent entry into the hazardous area, which is the area to be restricted.

[0045] <<Effects and Effects>> As shown in Figure 6, the access restriction cone X1 and access restriction cone bar Y1 alleviate or eliminate a predetermined misalignment that occurs between the erection member section screen s1 and the upright member section screen s2, thereby alleviating or eliminating the area in the gap between the erection member section screen s1 and the upright member section screen s2 where the presence or absence of restrictions is unclear. In particular, the access restriction cone X1 and access restriction cone bar Y1 are suitable for defining section screens that are linear or right-angled in a planar projection view.

[0046] <Second Embodiment> In the second embodiment, the entry restriction erection member X is an entry restriction pole X2, and the entry restriction erection member Y is an entry restriction rope Y2 that can be attached to an entry restriction cone.

[0047] As shown in Figure 7, the upright section 1 is formed in a columnar shape, and in particular, in a cylindrical shape.

[0048] The support portion 2 is formed in a plate shape that is large enough to encompass the bottom surface of the upright portion 1, and is particularly formed in a circular plate shape. The support portion 2 is formed integrally with the upright portion 1.

[0049] The erected portion 1 is erected approximately vertically from the vicinity of the inner edge of the convex hull of the support portion 2, and in particular, it is erected approximately vertically from the vicinity of the inner circumference of the support portion 2.

[0050] The mounting portion 3 is configured as an open hook. The mounting portion 3 is formed on the upper side of the upright portion 1, and in particular, on the tangential side of the circumferential portion of the support portion 2 that is close to the upright portion 1.

[0051] Based on the above configuration, the erecting portion 1 is configured such that, in a plan view, the mounting portion 3 is located on or near the edge of the convex hull t of the support portion 2 (particularly near the inner edge of the convex hull t of the support portion 2), and in particular, the mounting portion 3 is located on or near the edge of the support portion 2 (particularly near the inner edge of the edge of the support portion 2).

[0052] The rope used to restrict access, Y2, is a standard rope.

[0053] <<Effects and Effects>> As shown in Figure 8, the access restriction pole X2 and access restriction rope Y2 alleviate or eliminate a predetermined displacement that occurs between the erection member section screen s1 and the upright member section screen s2, thereby alleviating or eliminating the area in the gap between the erection member section screen s1 and the upright member section screen s2 where the presence or absence of restrictions is unclear.
