Abstract

<P>PROBLEM TO BE SOLVED: To cope with a serious social problem of bicycles parked on a sidewalk around a station, since they hinder safe traffic of pedestrians and cause a fear of hindering evacuation in a disaster. <P>SOLUTION: Sidewalk peripheral design secures safety on the sidewalk by restraining bicycle parking by making a vehicle body balance hard to keep when parking the bicycles by arranging a grating of a lattice shape in a construction material around a place for restraining the bicycle parking on a sidewalk surface. A projecting part is also installed on a grating surface, to cope even with restraint of the bicycle parking on a braille block by using for the braille block periphery for guiding a visually disabled person. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to sidewalk construction finishing materials and the surrounding environment design.

  The conventional sidewalk places the highest importance on the stability during walking for all people who are supposed to go through the place, and the shape of the finished surface and its construction material is uniformly flat. Yes, it is constructed in a shape that eliminates infinitely uniform irregularities.

According to the barrier-free concept in the conventional interpretation, a walkway with a flat surface can be said to be a very barrier-free design that is suitable for all pedestrians at first glance.
On the other hand, at the same time, it must be said that the shape is suitable for parking and parking bicycles and motorcycles.
As a result, bicycle bicycles overflow in inappropriate places on the sidewalk around the station, and can no longer play the original role of the sidewalk as a place for pedestrians to pass.

And bicycles parked on their sidewalks in a disorderly manner significantly damage the city's aesthetic landscape.
Bicycles that are parked also hinder safe pedestrian traffic during daily life. Bicycles parked in disorder and with their metal parts exposed are no longer a weapon in the city.
Furthermore, the path of visually impaired persons is blocked by bicycles parked on Braille blocks that are installed for the purpose of guiding visually impaired persons, and when welfare equipment such as wheelchairs pass through For this reason, there is not enough room, and the course is blocked.
In addition, for all people, it prevents smooth evacuation in an emergency or disaster and threatens even the safety of their lives, which is inconsistent with the idea of barrier-free.

  Therefore, an object of the present invention is to provide a safer road environment for all people by suppressing bicycle parking outside the designated place and realizing symbiosis between pedestrians and bicycles. .

In order to solve the above-mentioned problems, the first invention is to use, as a surface finishing material, a grating obtained by processing metal, stone, resin, concrete, wood and composite materials thereof into a lattice shape on a surface finishing member of a sidewalk. It is a sidewalk design characterized by restraining bicycle parking.
Grating is a grid-like groove cover that is usually used on drainage grooves.
The second invention is the arrangement and pattern of the grating designed to effectively prevent parking.
The third invention is a grating design in which the angle of the lattice is adjusted to suppress parking of a center stand type bicycle.
The fourth invention is a grating projection that is designed to suppress parking near the Braille block for guiding the visually impaired and a grating including the projection.

By encouraging bicycle parking at an appropriate bicycle parking facility by the effect of the present invention, it is possible to suppress parked parking outside the designated place on the sidewalk, and it is an obstacle when pedestrians pass on the sidewalk. You can remove the bicycle from the sidewalk.
At the same time, by providing the bicycle parking facility separately from the sidewalk, it is possible to separate the traffic lines of bicycles and pedestrians that would otherwise be classified as vehicles under the Road Code, improving safety on the sidewalk. To do.

  Also, by attaching a braille block-shaped projection directly on the surface of the grating and installing it instead of the braille block, parking can be suppressed even around and directly above the braille block, allowing safe passage for visually impaired persons. become.

  In addition, by making the surface of the sidewalk relatively easy to remove, it is possible to maintain, repair, and repair lifeline piping such as electricity, water, gas, and communications, and cables that are normally buried underground. In some cases, each time the ground surface was dug up, which was always a relatively large construction, the grating part was operated as a maintenance hatch, and various pipes were installed together in the lower space. Piping maintenance and renovation work do not require road excavation, which can shorten the construction period and reduce waste materials.

First of all, it is essential to provide a designated bicycle parking facility at a location where it is possible to prevent parking and to secure safety in close proximity. This is because if there is no bicycle parking facility that serves as a receiving tray when the bicycle parking is unilaterally suppressed, it will not solve the problem just by moving to another place and overflowing on another sidewalk.
At the same time, it is of course preferable that the parking facility be close to the place where parking should be suppressed for smooth parking guidance, but from the safety standpoint of separating the flow lines of bicycles and pedestrians. Rather, it is more desirable that the structure is connected to the roadway and separated from the sidewalk.

FIG. 1 shows an embodiment of the present invention.
The surface material for construction is a grid-like grating in FIG. 1 around a place where it is possible to judge that parking should be particularly suppressed on a sidewalk or the like, or around a Braille block for guiding a visually impaired person.
There are innumerable grooves as gaps in the lattice-shaped grating on the surface of the grating-like grating, and when this groove catches the bicycle stand and tries to park, the car body falls down, It becomes an obstacle.

FIG. 2 is a diagram showing the pattern arrangement of claim 2.
In general, assuming a form where the bicycle is parked on a sidewalk, the arrangement of the grooves that are considered to be effective for this is patterned into three patterns. However, this does not apply to operations where there are unusual circumstances.
Between reference numbers 2 and 3, the approximately 30-cm wide part has a long groove in the direction that intersects the sidewalk direction and 90 degrees perpendicular to the center stand type bicycle that is parked in parallel with the sidewalk. Deploy.
Between 3 and 4, the part with a width of approximately 60 centimeters is effective for a bicycle parked in an oblique direction with respect to the sidewalk. A longitudinal groove is arranged. Depending on the situation, the area between the code 3 and the code 4 may be divided into a plurality of patterns of about 30 to 60 degrees.
FIG. 3 is a schematic view of the rear wheel and stand of a bicycle that is about to be parked obliquely on the grating of the pattern 3 to 4 in FIG. Half of the stand falls into a groove that is alternately inverted at a certain distance and tilts.
Beyond between 4 and 5, the sidewalk is effective for center stand type bicycles that park around 30 centimeters or more and the Braille block for visually impaired guidance at right angles to the sidewalk. A longitudinal groove is arranged in parallel with the direction.

The standard size of each groove is about 3 centimeters on the short side and about 15 centimeters on the long side.
The short 3cm is wider than the tip of a standard bicycle stand and narrower than the width of a standard wheelchair wheel, and it is set so as to prevent the normal traffic as much as possible. This is the basis for this.
The length of the long side is more than about half of the width of the general center stand type bicycle stand, about 20 centimeters. If you try to park the bicycle, one side half of the bicycle stand will fall into the groove, I can't park because my bicycle falls down.

4 to 7 are views of the embodiment of the Braille block-like projection according to the fourth aspect.
As shown in FIG. 4 and FIG. 6, the projection 7 and the projection 13 are attached to the surface of the grating and operated in the same manner as the braille block. There are two types, one used for a straight line portion and the other used for a portion that calls attention, like a normal Braille block.

FIG. 4 and FIG. 5 are embodiments of protrusions when used in places that require attention such as corners.
There are a system in which an arm 8 connecting the projection 7 extends left and right from the tip, sandwiches the grid 9, and a bolt 10 threaded on the tip of the arm 8 is fastened with a nut 11 and fixed directly. .

6 and 7 are used for the straight portion of the Braille block type projection.
The protrusion 13 and the washer 14 are fixed by sandwiching the grating 18 with the bolt 15 or the bolt 16 and the nut 17.

"Effect of the embodiment"
According to this embodiment, only the bicycle stand can be effectively dropped into the groove of the grating of the grating, and the bicycle falls down because the inclination between the tire and the stand is not suitable for parking. Therefore, it is difficult to park at the place.
In this way, parking is suppressed.
Further, by appropriately setting the width and shape of the groove of the grating, the surface on the lattice is flat, so that there is almost no influence when passing by wearing ordinary shoes. However, if it is assumed that high heel wearers will pass, it is not appropriate to construct a part of the width with the same surface material as before and to construct the entire width with grating.

"Other embodiments"
In the embodiment of FIG. 1, the grating-like grating is used. However, in other embodiments, a tile having a shape in which a plurality of grooves having a certain depth or more are provided so as to have the same effect as the grating described above. good.

It is a perspective view which shows one Embodiment of this invention. FIG. 3 is a plan view of an embodiment of the present invention according to claim 2. It is the pattern design of the grating by Claim 3. FIG. 6 is a perspective view of an embodiment of a Braille block-like protrusion at a location to call attention of the present invention according to claim 4. FIG. 6 is a plan view of an embodiment of a Braille block-like protrusion at a location to call attention of the present invention according to claim 4. It is a perspective view which shows one Embodiment of the braille block-shaped protrusion for linear parts of this invention by Claim 4.
