[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sidewalk / roadway boundary partitioning device and a sidewalk / roadway boundary partitioning device that are installed along a boundary region between a sidewalk and a roadway such as a pedestrian crossing, and that allow a pedestrian or the like to distinguish between the sidewalk and the roadway. The present invention relates to a curb guide block body to be used.
[0002]
[Prior art]
The sidewalk / roadway boundary sorting device (hereinafter, abbreviated as the sorting device) 100 is generally formed in a substantially horizontally long rectangle by precast concrete along the boundary region between the sidewalk 101 and the roadway 102 as shown in FIGS. Further, the sidewalk 101 and the roadway 102 are divided by arranging a plurality of curb block bodies 103a to 103n side by side in the length direction. The sorting apparatus 100 is sufficiently high between the sidewalk 101 and the roadway 102 so as to clearly discriminate the sidewalk 101 and the roadway 102 in a place that is not a pedestrian crossing and prevent the vehicle from getting on the sidewalk 101. The level | step difference which has thickness is comprised. Further, the sorting apparatus 100 is formed to have a low height in accordance with the sidewalk 101 with a downward slope in order to allow an elderly person, an infant, a handicapped person, or the like to walk safely at a pedestrian crossing site.
[0003]
As shown in FIG. 10, the sorting apparatus 100 can be used to safely walk while distinguishing the sidewalk 101 and the roadway 102 with a walking stick, for example, at a pedestrian crossing site. Curb block bodies 104a to 104m are embedded with a step 105 between the surface and the road surface. In the sorting apparatus 100, the step 105 provided on the pedestrian crossing is set to a height that does not hinder the walking of the elderly and the like, and the visually handicapped etc. can be discriminated at the tip of the cane. A guide reference in which 105 is about 20 mm is set.
[0004]
By the way, for the user M of the wheelchair 120, there is an obstacle that is not a healthy person anywhere in the outdoors, such as a pedestrian crossing where no signal is installed or a crossing with a short signal time. The mental burden of traveling on the sidewalk is extremely large. For the user M of the wheelchair 120, the step 105 constituted by the sorting device 100 provided in the above-described pedestrian crossing or the like is also a big burden to get over the step after crossing the pedestrian crossing.
[0005]
That is, as shown in FIG. 10, the wheelchair 120 generally includes a pair of left and right large-diameter main wheels 122a and 122b provided with hand-rotating rings 121a and 121b, and a pair of left and right small-diameter front wheels 123a and 123b (only one 123a). Is shown).) Is provided. The user M of the wheelchair 120 moves the hand ring 121a, in order to get over the step 105 of only about 20 mm constituted by the sorting device 100 by the small-diameter front wheels 123a, 123b hitting the curb block body 104. 121b must be rotated with great force.
[0006]
In addition, when the wheelchair 120 rides on the step 105, the wheelchair 120 may present a dangerous situation by running excessively on the sidewalk 101 at a steep speed. The wheelchair 120 is also provided with, for example, an electric wheelchair that mounts a battery and a motor to drive the main wheels 122a and 122b. However, the problem of the event that occurs when the front wheels 123a and 123b hit the step 105 is a manual wheelchair. It occurs in the same way as 120.
[0007]
The conventional sorting apparatus 100 can travel relatively smoothly because a descending slope is added to the user M of the wheelchair 120 crossing the pedestrian crossing when entering the roadway 102 from the sidewalk 101. However, the problem described above is caused when the vehicle crosses the intersection and rides on the sidewalk 101 from the roadway 102. Further, the conventional sorting apparatus 100 is impatient for the user M of the wheelchair 120 when the front wheels 103a and 103b hit the step 105 and stop once when crossing the intersection and riding on the sidewalk 101. There is also a risk that the operation may be mistaken.
[0008]
In order to enable the wheelchair 120 to cross safely, a so-called barrier-free pedestrian crossing is proposed in which the step 105 by the sorting device 100 is eliminated between the sidewalk 101 and the roadway 102 (for example, a patent). Reference 1). This prior application structure is constructed by continuously forming the sidewalk surface and the road surface with the slope of the required slope, so that the elderly and infants can walk safely without any steps and rainwater that falls on the road The structure is such that the water collecting function is not impaired by guiding the water to the apron.

To. The sorting apparatus 100 does not form a step 105 between the sidewalk surface and the road surface so that an elderly person, an infant, or a user M of the wheelchair 120 can smoothly cross the roadway 102 at a location such as a crosswalk. Is preferred. On the other hand, the sorting apparatus 100 needs to identify the crossing by making the step 105 perceived when the visually impaired person has crossed the pedestrian crossing, and gives a sense of security.
[0011]
The structure of the barrier-free pedestrian crossing of the prior application described above makes it possible to identify the sidewalk 101 for visually impaired persons by providing the Braille block 106 over the entire area. On the other hand, it becomes an obstacle to walking and also an obstacle to running of the wheelchair 120. Therefore, it is considered that the barrier-free pedestrian crossing is provided with a portion where the Braille block 106 is not installed in a part 107 as shown in FIG. 9, but when the visually handicapped person happens to cross this area, the sidewalk 101 There is a problem that it is not perceived that it has reached the point, and this causes trouble.

[0038]
In the sorting apparatus 1, as described above, the first curb guide block body 7 to the third curb guide block body 9 form arcuate corner portions on the side surfaces 7 d to 9 d on the side of the roadway 3. Therefore, in the sorting apparatus 1, it is not necessary for the wheelchair 120 that has crossed the roadway 3 to get over the step 4, and the front wheels 123a and 123b can be smoothly guided into the wheelchair travel guide passages 10. . In the sorting apparatus 1, the user M of the wheelchair 120 can enter the sidewalk 2 from the road 3 without being impatient, thereby preventing an accident such as a fall.
[0039]
The sorting apparatus 1 includes, for example, the first curb guide block body 7 or the upper surfaces 7e to 9e of the second curb guide block body 8 and the third curb guide block body 9 together with the first curb guide block body 7. Each may be colored, for example, light blue or an appropriate color. The sorting apparatus 1 enables the pedestrian or the user M of the wheelchair 120 to visually recognize the formation position of the wheelchair travel guide passage 10 more quickly by the colored portion. Moreover, you may make it the sorting apparatus 1 make each upper surface 7e-9e of the 1st curb guide block body 7 thru | or the 3rd curb guide block body 9 into the rough surface of a non-slip | skid.
[0040]
In the sorting apparatus 1, as described above, the first curb guide block body 7 to the third curb guide block body 9 are aligned along the boundary region between the sidewalk 2 and the roadway 3, and are installed independently. . In the sorting apparatus 1, concrete or asphalt is placed for paving the sidewalk 2, and the first curb guide block body 7 to the third curb guide block body 9 formed relatively light at that time are placed. Misalignment may occur.
[0041]
Therefore, in the sorting apparatus 1, a connection structure for connecting the first curb guide block body 7 to the third curb guide block body 9 to each other is provided so as to prevent the occurrence of the above-described misalignment. May be. For example, as shown in FIG. 5, the connecting structure includes cylindrical insert nuts 13 a to 13 d provided in the first curb guide block body 7 to the third curb guide block body 9 and the insert nuts 13 a to 13 d. It is comprised from the space | interval holding rod 14a, 14b to connect.
[0042]
In the first curb guide block body 7, insert nuts 13a and 13b are insert-molded so that the openings are exposed on both side surfaces 7b and 7c, respectively, at the time of molding. Further, the second curb guide block body 8 and the third curb guide block body 9 are also opened in the respective side surfaces 8b and 9b facing the side surfaces 7b and 7c of the first curb guide block body 7 during molding. Insert nuts 13c and 13d are insert-molded so as to expose the portion. The insert nuts 13a to 13d are positioned coaxially with each other and are insert-molded in the first curb guide block body 7 to the third curb guide block body 9, respectively.
