Description

[Technical Field]

[0001] The present invention relates to a covering plate with a step-adjusting slope to be installed on a station platform. [Background technology]

[0002] In recent years, when construction work is carried out on station platforms, covering plates are laid to temporarily allow passage through the construction area. In this case, if the height of the station platform is lower than the planned height, a step will be created between the covering plate and the station platform when the covering plate is laid at the planned height. This step can cause an accident if a passerby trips over it, so it is necessary to eliminate this step. For this reason, ramps such as those shown in Reference 1 have attracted attention.

[0003] Document 1 discloses a step-leveling slope characterized by a long, plate-shaped slope body with a right-angled triangular cross section, which has a slit extending along the longitudinal direction of the slope body on its contact surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3242798 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the step-eliminating ramp described in Reference 1 does not take into consideration the risk of the ramp bouncing back when pedestrians walk on it. As a result, the step-eliminating ramp described in Reference 1 has the problem that the ramp will bounce back when pedestrians walk on it, and there is a possibility that the pedestrians may get their feet caught on the edge of the bouncing ramp.

[0006] Therefore, the present invention was devised in consideration of the above-mentioned problems, and its object is to provide a covering plate with a step-adjusting slope that does not cause rebound. [Means for solving the problem]

[0007] The lining plate with a step-adjusting slope according to the first invention is a lining plate with a step-adjusting slope that is installed on a station platform, and includes a slope having a plate material that slopes downward in a direction away from the lining plate, a rotating part that extends from the side of the lining plate and is capable of changing the angle of the slope, and a slope that is located above the rotating part and between the side of the lining plate and the opposing surface of the slope that faces the side. A rod-shaped object with a circular cross section that penetrates Equipped with cam The angle between the upper surface of the plate and the opposing surface is an acute angle, and the cam is in contact with the opposing surface. It is characterized by:

[0008] The covering plate with a step-adjusting slope of the second invention is characterized in that, in the first invention, the opposing surface is formed in a convex L-shape in the direction away from the covering plate in a cross section perpendicular to the rotational axis direction of the rotating part. [Effects of the Invention]

[0009] According to the first and second inventions, the cam is provided above the rotating part and between the side surface of the covering plate and the opposing surface of the slope facing the side surface. Therefore, when a force is applied in a direction that causes the slope to rebound, the opposing surface is engaged with the cam, making it possible to prevent the rebound.

[0010] In particular, according to the second aspect of the present invention, the opposing surface is formed in a U-shape convex in the direction away from the covering plate in a cross section perpendicular to the rotation axis direction of the rotating part. This allows the opposing surface to be locked by the cam at a constant angle of inclination even when a force is applied in a direction that increases the inclination of the slope, making it possible to adjust the angle.

[0012] Hereinafter, the covering plate with a step-adjusting slope according to the present invention will be described in detail with reference to the drawings.

[0013] First, the lining plate 10 with a step-adjusting slope according to this embodiment will be described with reference to Figures 1 to 4. Figure 1 is a perspective view schematically showing the lining plate 10 with a step-adjusting slope according to this embodiment. Figure 2 is a vertical arrow view schematically showing the lining plate 10 with a step-adjusting slope according to this embodiment. Figure 3(a) is a perspective view schematically showing the back side of the slope 2 according to this embodiment. Figure 3(b) is a perspective view schematically showing the front side of the slope 2 according to this embodiment. Figure 4 is a cross-sectional view perpendicular to the y direction schematically showing the lining plate with a step-adjusting slope according to this embodiment. In the figures, the x direction indicates the horizontal direction away from the lining plate 1, the y direction indicates the direction of the rotation axis of the rotating part 24, and the z direction indicates the vertical direction.

[0014] The lining plate 10 with a step-adjusting slope according to this embodiment is a lining plate 1 for temporarily allowing passage through a construction site during construction of a station platform, as shown in Figures 1 to 4. The lining plate 10 with a step-adjusting slope also includes a slope 2 for eliminating the step between the lining plate 10 with a step-adjusting slope and the station platform 3 when the height of the station platform 3 is low.

[0015] The covering plate 10 with a step-adjusting slope comprises a covering plate 1 to be installed on a station platform, a plate material 21 that slopes downward in the x direction away from the covering plate 1, a slope 2 that extends from the side surface 1a of the covering plate 1 and has a rotating part 24 that can change the angle of inclination θ, and a cam 4 that is located above the rotating part 24 and between the side surface 1a of the covering plate 1 and the opposing surface 23a of the slope 2 that faces the side surface 1a.

[0016] The slope 2 includes, for example, a bolt 22 protruding from the side surface 1a of the lining plate 1, a rotating portion 24 provided on the head of the bolt 22, frame portions 23 provided on both sides of the rotating portion 24 in the y direction and having an upper surface 23b formed as an inclined slope, and a plate material 21 provided on the upper surface 23b of the frame portion 23. The slope 2 may also be provided with an abutment portion 25 that abuts against the side surface 1a of the lining plate 1. The slope 2 is made of steel, but is not limited to this and may be made of any material such as resin. The slope 2 and the lining plate 1 may also be provided with an anti-slip function.

[0017] The bolt 22 is, for example, a den-den bolt, part of which is embedded in the side surface 1a of the covering plate 1 and has a ring-shaped head extending from the side surface 1a of the covering plate 1, but is not limited to this and any bolt may be used.

[0018] The rotating portion 24 is a connection portion between the bolt 22 and the frame portion 23. The rotating portion 24 is composed of a bolt or the like that penetrates the head of the bolt 22 and the frame portions 23 provided on both sides of the head so that the bolt 22 can rotate around the y direction as the rotation axis, for example. The rotating portion 24 is provided so that when the bolt 22 is fixed to the covering plate 1, the frame portion 23 can rotate as the bolt 22 rotates around the y direction as the rotation axis.

[0019] The frame portions 23 are formed in a plate shape and are provided on both sides of the rotating portion 24 in the y direction so as to face each other. The frame portions 23 are provided, for example, so that the angle of inclination θ of the upper surface 23b varies as the rotating portion 24 rotates. The frame portions 23 are formed in a tapered shape such that the width B between the upper surface 23b and the lower surface 23c decreases, for example, in the x direction. The lower surface 23c of the frame portion 23 may be provided so as to be parallel to the upper surface of the station platform 3, but is not limited to this and may have any shape.

[0020] The frame portion 23 also has an opposing surface 23a that faces the side surface 1a of the covering plate 1. For example, the opposing surface 23a is formed in a dogleg shape with a protrusion A that is protruding in the x direction in a cross section in the y direction, but is not limited to this, and the opposing surface 23a may be provided so that the angle Φ between the upper surface 23b and the opposing surface 23a is an acute angle. Furthermore, the opposing surface 23a is provided so that the protrusion A of the dogleg is above the rotating portion 24, for example.

[0021] The abutment portion 25 has an abutment surface 25a that abuts against the side surface 1a of the covering plate 1 and is penetrated by the bolt 22, and a lower end surface 25b that is bent in the x direction from the lower end of the abutment surface 25a and comes into contact with the frame portion 23. The abutment surface 25a of the abutment portion 25 is provided spaced apart from the frame portion 23, but this is not limited to this.

[0022] The cam 4 is provided above the rotating portion 24 and between the side surface 1a and the opposing surface 23a. The cam 4 may also be provided on the protruding portion A. The cam 4 is formed, for example, in a rod shape so as to penetrate between the side surface 1a and the opposing surface 23a in the y direction. The cam 4 is welded, for example, to the x-direction side of the abutment surface 25a, but is not limited to this and may be provided by any method. The cam 4 is formed so that its cross section in the y direction is circular, but is not limited to this and may be formed in any shape.

[0023] Next, a method for installing the step-adjusting slope-equipped lining plate 10 according to this embodiment will be described with reference to FIGS.

[0024] The lining plate 10 with a step-adjusting slope is installed on the station platform 3 as shown in Figure 4. After the lining plate 10 with a step-adjusting slope is installed, the inclination angle θ of the slope 2 is adjusted so as to eliminate the step between the lining plate 1 and the station platform 3.

[0025] In this case, by rotating the rotating part 24 in the r direction, the angle θ of inclination can be adjusted so that the angle θ of inclination increases. Furthermore, when the angle θ of inclination increases to a certain value as shown in Fig. 5, the convex part A of the opposing surface 23a is engaged with the cam 4, so that the angle θ of inclination cannot be increased beyond the certain value. The angle θ of inclination is, for example, 5.0° to 12.0°, but is not limited thereto and may be set to any angle within the range.

[0026] Furthermore, when a force is applied to the rotating portion 24 so as to rotate it in the direction opposite to the r direction, the opposing surface 23a is locked by the cam 4, so that it is possible to prevent the slope 2 from bouncing back.

[0027] According to the covering plate 10 with a step-adjusting slope according to the present embodiment described above, the cam 4 is provided above the rotating portion 24 and between the side surface 1a and the opposing surface 23a of the covering plate 1. Therefore, when a force is applied in a direction that causes the slope 2 to bounce back, the opposing surface 23a is engaged with the cam 4, making it possible to prevent the rebound.

[0028] Furthermore, according to the covering plate 10 with a step-adjusting slope according to this embodiment, the opposing surface 23a is formed in a V-shape that is convex in the x direction away from the covering plate 1 in a cross section perpendicular to the y direction of the rotation axis of the rotating part 24. As a result, even when a force is applied to rotate the rotating part 24 in the r direction in which the angle of inclination θ of the slope 2 increases, the opposing surface 23a is engaged with the cam 4 at a constant angle of inclination θ, making it possible to adjust the angle of inclination θ.

[0029] 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 embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the inventions described in the claims and their equivalents.
