DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 (a) to 1 (d) are a side view and a front view showing a basic form of a protective fence. Hereinafter, an embodiment to which the present invention is applied for each basic form will be described in detail.

The basic form of the protective fence is shown in FIGS.
FIG. 1D shows a “center beam type” in which a fence is erected via a joint 1 on a line of a pillar cross-section center line between pillars 3 erected at appropriate intervals as shown in FIG. It is roughly classified into a "front beam type" in which a fence is erected via a joint 1 on the front surface of a column 3 which is erected at appropriate intervals.
Here, the fence means a beam 5 formed by a tube or the like as shown in FIGS. 1 (b) and 1 (d), and between the upper and lower horizontal beams (also called beams) as shown in FIGS. 1 (a) and 1 (c). The term "fence panel 4" in which a large number of vertical rails are attached at their ends, such as a fence panel 4, etc. It is. In addition, the joint is provided between the support and the fence when the fence is erected, is attached to the support, and supports the fence to connect the support and the fence. When used at the seam of a beam to be connected in the case of a beam, it also functions as a fence component for connecting the beams.

FIGS. 2A and 2B are exploded views showing a connecting portion between a column and a beam in the configuration of the "center beam type" protective fence shown in FIG. 1A, and FIG. is there. This “retaining pin type” guard fence has a pin hole 5 at the end.
A joint having a ring body 12 formed with a through hole 11 through which an end portion of the beam 5 provided with 1 is inserted, and a locking portion 13 locked with a beam hole 31 formed in a side surface of the support 3. 1
Is fixed to the beam hole 31 of the column, and the through hole 1
The end of the beam 5 is inserted from the beam hole 31 of the column by inserting the end of the beam 5 into 1 and the retaining pin 52 penetrating all the pin holes 51 at the ends of the plurality of beams 5 inserted into the column 3. The joint 1 serves to support the end of the beam 5 and to fix the end of the beam 5 so that the beam 5 does not rattle with respect to the column 3. Also plays.

FIGS. 3A and 3B show an example of an embodiment in which the joint with a reflector according to the present invention is applied to this "retaining pin type" protective fence. FIG. 3A is a perspective view of the joint with a reflector, and FIG. In the sectional view, a part of the ring body 12 of the joint 1 which is interposed between the column 3 and the beam 5 and serves to connect the beam 5 to the column 3 and to prevent rattling at the connection portion. Body 2 is attached. In this embodiment, the joint 1 is manufactured by injection molding using a resin material. However, the joint 1 may be manufactured using a metal plate material such as a spring steel material. Any joint that serves to connect the beam to the strut and to prevent rattling at the connection portion can be used as a joint with a reflector as in the case of the injection molded product.

Here, the reflector is a "reflection sheet" in which a reflection film is provided on a sheet-like base material and a number of spherical lenses such as transparent glass are disposed thereon, or an air layer is provided on the front surface of the substrate. Manufactured by a "prism reflector" manufactured by disposing a lens body made of transparent plastic such as polycarbonate or acrylic through a "prism reflector", or a "prism reflector sheet" in which the substrate of this "prism reflector" is a sheet-like thin plate The mirror is attached to the reflector base 24 made of resin as shown in FIG. 4, and a mirror surface is formed on the bottom surface of the sphere 26 to provide a retroreflective transparent member. "Bead buried reflector" in which a reflector 25 made of a transparent glass bead is buried in a semi-buried state
When 21 is used, the material of the reflector is glass, so there is no need to worry about deterioration in weather resistance, and it is preferable because it has good durability and can maintain a high reflection effect.

FIG. 4A is a perspective view of a joint representing another example similar to the embodiment of FIG. 3, and FIG.

The bottom surface of the sphere 26 constituting the reflector 25 is mirror-finished so as to be reflected in the opposite direction to the incident direction of light as shown by the light trace indicated by the arrow in the drawing to reflect light. In this example, a mirror surface is formed on the reflective surface 27 of the transparent glass beads by plating evaporation. Further, the sphere 26 constituting the reflector 25 is made of a transparent glass or a transparent resin glass that transmits light, and depending on its use, for example, "yellow" is used for a warning sign for danger prevention, and from the image of security, safety, and landscape protection. It is used after being colored such as "green", other "blue", and "red". In the case of no coloring, the illuminance of the reflected light is higher than in the case of coloring, and in addition, it will be described later. Is opposed to light arriving from the vehicle or the like to which the center line 8 of the retroreflection of the reflector 2 is irradiated, and since the reflector base 24 is attached to the joint 1, an efficient reflection effect can be obtained. If, for example, the joint with the reflector is applied to all the joints interposed between the pillars and the pillars of the protective fence along the roadway on which the vehicle travels at a high speed, an extremely high gaze guidance effect can be obtained.

The reflector base 24 is preferably made of a resin material, such as polyethylene resin or ABS resin, which is in close contact with and holds the embedded glass bead reflector 25, and is generally colored black. It is excellent in weather resistance and is preferable from the viewpoint of durability. Here, the reflector base 24
On the other hand, a large number of reflectors 25 made of glass beads are manufactured by insert injection molding using these reflectors 25 as insert parts, or previously formed depressions approximate to the outer shape of the reflector 25 made of glass beads. In addition, the reflector 25 is fitted in a later step to manufacture.

The reflector 2 in the embodiment shown in FIG. 4 has a mirror surface treatment for reflecting light on the bottom surface of the reflector 25. The sphere made of glass beads to be buried is replaced with a transparent sphere 26.
Alternatively, the sphere holding surface of the reflector base body 24 which is in close contact with the mirror body may be subjected to a mirror surface treatment so that a similar retroreflection effect can be obtained.

Further, in the case of the embodiment shown in FIG. 4A, a resin reflector base 24 in which a reflector 25 made of glass beads having a retroreflective property with respect to the joint 1 is embedded in a semi-embedded state. Although the description has been made with reference to the attached embodiment, the present invention is applied to a case where the main body of the joint 1 molded of resin is integrally molded as a reflector base, and the reflector 25 made of glass beads is directly embedded in a semi-embedded state.

The joint with reflector need not necessarily be attached to all joints of beams such as a fence attached to a support. If the target light is a headlight of a vehicle, its focused irradiation height 150-3 on the ground based on
It is suitable to be attached only to beam joints such as fences that are installed at a relatively low height of about 00 mm. In the case of fall prevention fences and crossing prevention fences, consideration should be given to the height of the line of sight of people. It is appropriate to be installed at a relatively high position.

[0036]

As described above, in the fence with a reflector according to the present invention, a fence body is erected between supports erected at appropriate intervals via a joint, and the joint is a joint component of the fence. The reflector is attached, and the joint is incorporated into the basic structural members of the fence, so it is difficult for the mounting state to be distorted by external force such as a contact accident and it does not fall off. Since the construction of this fence with reflectors is performed without losing the effect and during the usual fence installation process, there is no extra work such as sticking the reflection sheet to the fence post, and the reflection sheet The appearance of the fence, such as sticking, is not impaired and the scenery is not hindered.

Further, in the center beam type fence of the fence with a reflector according to the present invention, the joint is engaged with the beam hole formed in the side surface of the support by a ring body having a through hole formed through the beam end. When the reflector is attached to this ring, the reflector does not fall off because the beam end is inserted through the ring of the joint, and the joint does not fall out. Since the locking portion formed on the ring body is locked in the beam hole on the side surface of the support, the ring body on which the reflector is mounted is not distorted in the mounted state such as rotation, and therefore, the predetermined fence as set. The night visibility effect is not lost. In addition, since the joint with the reflector does not protrude from the width of the column, it does not cause a contact accident, and there is no fear of contact with the joint with the reflector. There is no fear of doing.

Further, in the center beam type fence of the fence with a reflector according to the present invention, the joint comprises a cylindrical supporting portion for inserting a beam end and a fixing portion for fixing the supporting portion to a side surface of the column. When the reflector is attached to the support or the fixing part, or both, the beam end is inserted into the cylindrical support of the joint, and the support is fixed to the side surface of the support by the fixing part. Since the reflector does not fall off and is fixed to the side of the column, the joint is not distorted due to rotation or the like, so that the night visibility effect of the predetermined fence as set is lost. Nothing. In addition, since the joint with the reflector does not protrude from the width of the column, it does not cause a contact accident. There is no fear of loss.

In the center beam type fence of the fence with a reflector according to the present invention, the joints are projected from the end of the fence body and the side surface of the support so as to face each other, and the two joints are combined with each other. When a reflector is attached to a joint used for a fence in which the fence is erected between the columns, these joints are protruded from the end of the fence and the side of the column and are combined and connected. Since the reflectors attached to these joints do not fall off and the joints do not distort the mounting state such as rotation, the reflectors attached to them have the effect of night visibility of the specified fence. Never lose. In addition, the joint with a reflector does not protrude from the width of the column, so it does not cause a contact accident, and there is no risk of contact with the joint with a reflector, so the reflectivity is lost due to damage. There is no fear of doing.

Alternatively, in the front beam type fence of the fence with a reflector according to the present invention, the joint is fixed to the front surface of the column, and further comprises a support fitting for supporting the beam and a fixing fitting for fixing the beam to the support fitting. The supporting member and / or the fixing member, or a member in which a reflector is attached to both, or the supporting member, the fixing member, or a cover material in which the reflecting member is attached to both or both of the supporting member and the cover member When the reflectors are attached to the joints via the joints, in each case the reflectors are in front of the strut (i.e. on the side where the vehicle runs when this fence faces the road). ) Since it is attached, night visibility is enhanced, and the night visibility effect of the fence, which is the fundamental function of the reflector, is sufficiently exhibited. Also,
If a reflector is attached to the joint via a cover material, the cover material with the reflector can be attached as necessary, so that this fence attached only to dangerous parts such as curves can Focused installation is performed only at locations where gaze guidance is required, enabling an economical construction form.

In the fence with a reflector according to the present invention, a reflector is attached to a lateral beam end of a fence in which a fence is erected through a joint between columns erected at appropriate intervals. If a cap is installed, the visibility of the beam end, which is the end of the fence, is improved to avoid the danger of vehicles etc. coming into contact with the fence, or the fence panel is constructed as a fence body. By a cap with reflector at the end of the transverse beam which constitutes the fence panel placed between each strut,
The gaze guidance effect of the fence at night is enhanced.

In the fence with a reflector according to the present invention, when the reflector to be mounted has a retroreflective property when a reflector made of glass beads is buried in the base in a semi-buried state. Since the reflector is made of glass, there is no need to provide a protective film coating layer on the front of the reflector, and the reflection efficiency is extremely high and the durability is good. Can be maintained.

In the fence with a reflector according to the present invention, the reflector faces a light source such as a headlight of a vehicle.
If the reflecting surface of the reflector is formed at an acute angle with respect to the center line of the core as the bridge of the fence body, it is faced straight toward the center line of the incident light such as a headlight reaching the reflector. Since the reflector is installed, the reflector is installed in a state where the reflection efficiency is highest for the target light source such as a vehicle or a bicycle approaching the fence to which the reflector is attached. The night visibility effect of the fence is obtained.

The joint with reflector attached to the fence with reflector of the present invention is an assembly component of the fence used for erection of the fence between the columns erected at appropriate intervals. Since the reflector is attached to the joint and incorporated as a part of the basic construction of the fence, the mounting state is not easily distorted by external force such as a contact accident and it does not fall off. Since the effect of night visibility is not lost, and the fence with the reflector is constructed during the normal fence installation process, extra work such as sticking a reflection sheet to the fence post is required. In addition, the appearance of the fence is not impaired as in the case of sticking the reflection sheet, and the scene is not harmed.
