Description

  The present invention relates to an attachment that can be easily attached to a pipe or a wire (cable).

In an everyday environment, there are many members that are installed independently, such as a part of a building or a structure composed of pipes and wires, such as a handrail, a pillar, a pole, a fence, and a guard cable, or some kind of pillar. These are equipped with various signs for hazard prevention, guidance or identification. In addition, labels such as labels and tags are used so that individual pipes can be identified even in places where many pipes are complicated.
There are many types of road-related things, such as pillars that support traffic sign boards, safety fences that separate sidewalks and roadways, guard cables and guard pipes that are placed in dangerous locations, and poles that indicate roadsides in heavy snow areas. There are also many.
The signs can be attached in the form of labels, stickers such as nameplates, hooked with wires, etc., or wrapped and screwed at both ends.

  When it is necessary to attach a large number of signs to a large area, it is desirable to be easy to install from the viewpoint of labor. It is important from the viewpoint of worker safety to be able to work quickly, especially on cliffs with poor working environments and highways with frequent traffic. In addition, it is preferable to have a structure that is uniform even when an unfamiliar operator attaches it, has durability, and cannot be easily removed to prevent tampering.

Provided is an attachment for a sign (referred to as a cylindrical sign attachment) that can be quickly attached to a pipe or wire.
In this case, the sign is generally used to guide the driver's or pedestrian's line of sight for risk prevention, guidance, or identification, as well as letters, symbols, and figures, as well as simple colors and light (phosphorescence, Fluorescence, reflected light, etc.) are also included.

The cylindrical sign attachment is opened in the axial direction so that the operator can hold it with one hand, fit it into the pipe or wire from the side, and then complete the attachment to the object with just one hand. That is, in the case of a pipe, it is a cylindrical body having a substantially C-shaped cross section taken along a plane orthogonal to the axial direction, and has a fixing means for an object.
The cylindrical body is formed by forming a flexible, flexible sheet body such as rubber, synthetic resin, metal, plastic magnet, or cardboard into a cylindrical shape. When the material is hard, the cylindrical body is divided into two parts and connected by a hinge part to form a cylindrical body whose side part is cut open.

The fixing means includes a structure in which both side incision edges of a cylindrical marker attachment fitted to an object are engaged by male / female fitting, a means using an adhesive, a means using magnetic force, and the like. Both are designed to function when the cylindrical sign attachment is clamped with one hand.
The sign part (the part that guides the driver's or pedestrian's line of sight) is formed on the outer surface or inner surface of the cylindrical body by means such as painting, printing, sticking of an adhesive sheet, stamping, embossing, or the like. In addition, a product made in the form of a sheet that does not have an adhesive surface is attached to the outer surface or inner surface of the cylindrical body, or a material with a different color is embedded when molding the cylindrical body, for example, a phosphorescent material is kneaded. It can also be formed by indentation.
In order to protect the sign portion from the external environment, a protective member may be further added to the cylindrical sign attachment.

It can be attached by attaching it to an object (such as a pipe) and holding it with one hand, so that it is possible to complete the work of attaching the sign in a short time even in a poor working environment.
No tools are required for the work, and no skill is required for the work.

  A cylindrical body whose side surface is cut open with a semi-rigid resin such as AES resin or recycled resin is formed. The cylindrical body has a diameter of about 60 mm and a length of about 100 mm, and can be handled with one hand and gripped in the circumferential direction. The cross section of the cylindrical body is substantially C-shaped, and a male engagement portion is formed on one of the opposed incision edges, and a female engagement portion is formed on the other. The incision edge is structured to be engaged by male / female fitting. A sign sheet having a phosphorescent part and a retroreflective part in parallel is attached to the surface of the cylindrical body to form a sign part. A phosphorescent part may be directly formed on the surface of the cylindrical body by printing, and a commercially available retroreflective sheet in the form of an adhesive sheet may be attached thereon to form a sign part.

In this state of attaching the cylindrical mark attachment to the object, since the side surface is cut open to be an opening, if the opening is directly applied to the object and pressed, Easily get into the object. Next, when the cylindrical body is squeezed, the incision edges on both sides abut and engage. With this alone, the cylindrical sign attachment is attached to the object, and no tools, tedious procedures or techniques are required for the attachment.
There are various objects to which this cylindrical sign attachment is attached. For example, if it is attached to a handrail, the position of the handrail is clearly indicated by the phosphorescent portion at night and becomes a warning sign that prompts the pedestrian to pay attention. In addition, it is dark and uneasy to pass through mountainous roads at night, but if this cylindrical sign attachment is attached to a pillar that supports the guardrail, the retroreflective part will be reflected and the road A feeling of security comes out because the bending condition is clearly shown. Furthermore, even when a person who does not have a light source such as a pedestrian passes along such a road, the phosphorescent portion serves as a road guide, and a sense of security is generated.

FIG. 1 shows a cylindrical sign attachment 1 as Example 1, and as shown in FIGS. 2 to 4, a pipe safety fence 2, a stair handrail pipe 3, a roadside instruction pole 4, or a traffic sign post pipe, as shown in FIGS. Used for 5.
The cylindrical marker attachment 1 is composed of a cylindrical body 6 and a marker portion 7. In the drawing, detailed dimensions such as thickness are exaggerated.
The cylindrical body 6 is made of a recycled resin mainly made of AES resin or recycled PET (* Eco-PET), and the side surface is cut open, and an opening 9 is formed between the incision edges 8a and 8b on both sides. Has been. Further, one incision edge 8a is slightly thicker (FIG. 5), the male engagement protrusions 10a are formed in series in the longitudinal direction, and the other incision edge 8b is also slightly thicker. The female-side engaging groove 10b is formed in a series in the longitudinal direction. The male side engaging protrusion 10a has a flange 11 at the tip, and the female side engaging groove 10b has a detent hook 12 at the bottom.

  The labeling part 7 is a commercially available adhesive sheet (marking sheet 15) in which the phosphorescent part 13 and the retroreflective part 14 are formed in parallel on the sheet surface, and is attached to the surface of the cylindrical body 6. The phosphorescent portion 13 is obtained by printing a phosphorescent material that radiates absorbed energy as light, and the retroreflective portion 14 fixes microbeads that reflect and shine light, such as nighttime automobile lights, to the surface with a transparent adhesive. It is a thing. You may adhere | attach the sheet | seat for independent phosphorescent parts, and the commercially available adhesive sheet for retroreflection parts alternately.

  As shown in FIGS. 6 (A) and 6 (B), for example, when the cylindrical mark attachment 1 is pushed into the pipe portion 16 of the safety fence 2 with the side opening 9 inserted, the cylindrical sign attachment 1 can be easily fitted as shown in FIG. 6 (C). Can be included. Next, when the tubular body 6 is clamped with one hand (FIG. 7), the incision edges 8a and 8b on both sides are engaged as shown in FIG. 6 (d), and the tubular marker attachment 1 is easily attached to the safety fence 2. It is attached. This means that the cylindrical body 6 only needs to have this degree of flexibility. If the material of the cylindrical body 6 is durable to the external environment, in addition to synthetic resin, rubber , Metal, plastic magnets, cardboard, etc.

In this embodiment, the diameter of the cylindrical body 6 is approximately 60 mm, the thickness is 2 mm (partially 3 mm), and the axial length is 50 mm. This dimension is suitable for handling and clamping with one hand. In addition, when the pipe is thin, the diameter can be 43 mm, and when it is attached to the wire, it can be made with various dimensions such as 18 mm. The length in the axial direction is about 50 to 120 mm as a guide for gripping with one hand and for the size required as a marker.
The attached attachment 1 cannot be released once engaged because of the hook 11 of the male engagement protrusion 10a and the hook 12 of the female engagement groove 10b, and is removed by mischief. There is nothing. The length in the axial direction may be 50 mm.

  As shown in FIGS. 2 to 4, it is necessary to attach a plurality of cylindrical sign attachments 1 at the same place and the same kind at many places over a wide area. According to the structure of the present invention, Since it can be fitted with only one hand, the work can be completed in a short time. Also, no special techniques or tools are required for the installation work.

In the cylindrical marker attachment 1 of FIG. 8, the cylindrical body 6 has a rectangular cross section and is adapted to a pipe portion 16 having a rectangular cross section. An opening 9 is provided, and incision edges 8a and 8b are formed.
The material of the cylindrical body 6 is the same as that of the first embodiment, and is flexible enough to expand the opening 9 of the incision end edges 8a and 8b when fitted into the pipe portion 16 and durable against the external environment. It only has to be prepared. The fixing means is an adhesive 17 formed on the inner surface of the cylindrical body 6. Although the adhesive material 17 is a double-sided pressure-sensitive adhesive tape in the embodiment, it is located on the inner surface of the cylindrical body 6 and is less likely to come into contact with other materials, so that the adhesive surface remains exposed. Although it is possible to attach the release paper to the surface of the adhesive 17 and peel it off when using it, it is preferable that the adhesive surface remains exposed in order to simplify and speed up the operation.

As in the first embodiment, after fitting into the pipe portion 16, the mounting can be completed by grasping with one hand. In this embodiment, the marker portion 7 is directly formed on the surface of the cylindrical body 6 by printing.
Thus, the cross-sectional shape of the cylindrical body 6 in the cylindrical marker attachment 1 can be variously selected according to the cross-sectional shape of the object to which the cylindrical body 6 is to be attached. Further, as described above, the sign 7 is not limited to sticking or direct printing of the sign sheet 15, but embedding, stamping or embedding or fitting at the time of molding such as partially changing the color of the material constituting the cylindrical body 6. Furthermore, it can be formed by means of, for example, kneading the phosphorescent material into the material.
In the second embodiment, as in the first embodiment, the male engaging protrusions 10a and the female concave grooves 10b may be formed on the incision end edges 8a and 8b to serve as fixing means by engagement.

  In the cylindrical marker attachment 1 of FIG. 9, a cushion portion 18 made of synthetic rubber or the like is formed on the inner surface of the cylindrical body 6. The incision edges 8a and 8b are configured as fixing means by male / female fitting. Due to the presence of the cushion portion 18, even when the surface of the mounting object has irregularities, it can be stably attached. In addition, the cushion portion 18 is elastically frictionally engaged with the surface of the object, and elastically eliminates play in the male / female fitting of the incision end edges 8a and 8b. The shape marker attachment 1 can be stably attached.

  In the cylindrical marker attachment 1 of FIGS. 10 to 12, the cylindrical body 6 is composed of divided cylindrical bodies 19 a and 19 b and a hinge part 20. The divided cylinders 19a and 19b are obtained by cutting a transparent MMA (acrylic resin) cylinder (diameter 60 mm, thickness 2 mm (partially 3 mm), axial length 50 mm) along the axial direction. Can be easily handled and clamped with one hand. MMA is a material excellent in weather resistance, transparency, and impact resistance.

The connecting side edges 21a and 21b and the connecting side edges 22a and 22b are set in the divided cylinders 19a and 19b, respectively (FIG. 11). Reference numerals 23a and 23b are front ends of the divided cylinders 19a and 19b, and 24a and 24b are rear ends.
The divided cylinders 19a and 19b are arranged with their inner sides facing each other, and the connecting side edges 21a and 21b are joined by a semi-rigid soft MMA. Soft MMA is flexible (flexible) and has elasticity to restore the bent state, and the connecting part is a hinge part that joins the split cylinders 19a and 19b on both sides so that they can be opened and closed. 20 (FIGS. 10 and 12).

  The connecting side 22a of the split cylinder 19a is slightly thickened and formed into a male engaging protrusion 10a, and the connecting side 22b of the split cylindrical body 19b is formed in the female engaging groove 10b. Molded. This male / female fitting structure is the same as that described in the first embodiment.

  Accordingly, as in the case of FIG. 7, when the cylindrical sign attachment 1 is held with one hand and is placed on the necessary part of the safety fence 2 and is squeezed, the divided cylinders 19 a and 19 b approach the hinge part 20 as the center. The male-side engagement protrusion 10a faces the female-side engagement groove 10b and is eventually fitted. Thereby, the divided cylinders 19a and 19b on both sides are integrally coupled. That is, the cylindrical sign attachment 1 can be easily attached to a target location of the safety fence 2 formed of a pipe.

  In the structure of the fourth embodiment, when the thickness is increased, the divided cylindrical bodies 19a and 19b can be made by using an acrylic resin that lacks flexibility, and a sturdy cylindrical marker attachment 1 can be obtained. The acrylic resin has high weather resistance and good colorability. The divided cylinders 19a and 19b may be polycarbonate resin or ABS resin in addition to acrylic resin, and semi-rigid or rigid resin can also be used. In this embodiment, the sign section 7 is printing, sticking the sign sheet 15, and the like.

The hinge part 20 can also be integrally formed simultaneously with the divided cylinders 19a and 19b. In addition to soft MMA, other synthetic resins having adhesiveness with MMA can also be used.
As described above, if the hinge part 20 is flexible and has some elasticity, the split cylinders 19a and 19b on both sides joined by the hinge part 20 are connected to the coupling side parts 22a and 22b before mounting. Can be opened by a certain angle (40 ° to 50 °, about the diameter of the target pipe). Thereby, when attaching the cylindrical marker attachment 1 to a pipe or the like, it is possible to work without opening it one by one. Moreover, since it is always urged | biased by the hinge part 20 in the opening direction, after attaching to pipes etc., the engagement state of the male side engaging protrusion 10a and the female side engaging groove 10b is stabilized.

FIGS. 13 to 15 show a cylindrical marker attachment 1 as a fifth embodiment, which includes a cylindrical body 6, caps 25 a and 25 b, and a marker sheet 15. As in the case of the fourth embodiment, the cylindrical body 6 is formed by connecting the divided cylindrical bodies 19a and 19b with the hinge part 20 and connecting the connecting sides 8a and 8b by male / female fitting. The caps 25a and 25b are mounted over the front ends 23a and 23b and the rear ends 24a and 24b of the divided cylinders 19a and 19b, respectively.
The caps 25a and 25b have the same configuration, are annular grooves cut at one place, and are formed of an elastomer such as a soft silicone resin. The above-mentioned cutting part corresponds to a joint part of the tubular body 6 by male / female fitting.
The caps 25a and 25b are attached to the cylindrical body 6 in advance, and then the entire cylindrical marker attachment 1 is attached to the object. Since the caps 25a and 25b are groove-shaped in cross section, when the cylindrical marker attachment 1 is attached, the inner edge is attached in contact with the object.

The caps 25a and 25b can have various functions.
When the cylindrical marker attachment 1 is attached to the object, the inner edges of the caps 25a and 25b are attached in contact with the object. For this reason, it can prevent that the attached cylindrical label | marker attachment 1 rotates along the surface of a target object, or moves to the longitudinal direction of a target object (cap | cap as a slipper). In order to strengthen this function, the inner edges of the caps 25a and 25b are formed long inward in the axial direction of the cylindrical marker attachment 1 or the like. The caps 25a and 25b serving as slip stoppers may be partial in the circumferential direction to the extent that they function as slip stoppers, rather than all of the front and rear edges of the cylindrical body 6.

In order to fit the male side engaging protrusion 10a and the female side engaging groove 10b after fitting the cylindrical mark attachment 1 to the object, the coupling side edges 22a and 22b of the cylindrical mark attachment 1 are used. Clearance is necessary between the object and the cylindrical marker attachment 1 so that the caps 25a and 25b can secure this clearance (to ensure clearance). Cap). In order to strengthen this function, the inner edges of the caps 25a and 25b are made thick and soft.
When the inner edges of the caps 25a and 25b come into contact with the object, the space between the outer surface of the object and the inner surface of the cylindrical marker attachment 1 is shielded from the outside, and rainwater and dust enter the space and become dirty. Can be prevented. For this purpose, protrusions and pleats protruding further inward may be provided in an annular shape on the inner peripheral surfaces of caps 25a and 25b (the side in contact with the outer surface of the object) (caps for dust prevention).

When the separate label sheet 15 is disposed on the inner surface of the cylindrical body 6, the edges of the label sheet 15 and the cylindrical body 6 are sandwiched between the inner and outer walls of the groove structure by the caps 25a and 25b. The space between the bodies 6 can be maintained substantially airtight (cap for airtightness). Thereby, it is easy to prevent the performance deterioration due to the sign sheet 15 coming into contact with the outside air. For this purpose, in the cross section of the caps 25a and 25b, in addition to the inner edge in contact with the outer surface of the object, a second inner edge in contact with the back surface of the marker sheet 15 is often formed. However, when the marker sheet 15 is thick, the second inner edge may not be required.
Since the caps 25a and 25b cover the edge of the cylindrical body 6, it is possible to prevent an operator from being injured by the sharp edge of the acrylic resin material (cap for protection).

FIGS. 14 and 15 show a cylindrical sign attachment 1 as a sixth embodiment, which schematically shows the fifth embodiment but specializes in traffic signs that stand out at night.
The cylindrical marker attachment 1 includes a cylindrical body 6, caps 25a and 25b for airtightness, and a sheet 26 (marker sheet 15) having a function of storing and retroreflecting light. Since the cylindrical body 6 and the caps 25a and 25b for airtightness are the same as those in the fifth embodiment, description thereof is omitted. However, the cylindrical body 6 is made of transparent MMA (acrylic resin).

The sheet | seat 26 provided with the light storage and retroreflection function has accumulated the light storage sheet | seat 27, the retroreflection sheet | seat 28, and the protective sheet 29 from the outer surface side. The phosphorescent sheet 27 is a phosphorescent material that radiates absorbed energy as light, printed on a PET or OPP (biaxially oriented polypropylene) sheet in a grid-like or uniformly dispersed state, and reflected from the back side. While allowing light to pass, it emits light for a long time. A commercially available product having a high afterglow brightness is used.
The retroreflective sheet 28 is a sheet in which micro beads are fixed to a sheet of PET or the like, and reflects and shines at night automobile light. A commercially available one is also used.
The protective sheet 29 is a sheet such as OPP or PET, and protects the inner surfaces of the phosphorescent sheet 27 and the retroreflective sheet 28.

  The phosphorescent sheet 27, the retroreflective sheet 28, and the protective sheet 29 are formed as a single sheet 26 having a phosphorescent and retroreflective function, and this is disposed on the inner surface of the cylindrical body 6. Airtight caps 25a and 25b attached to the front end and the rear end are sandwiched and fixed. Further, a dust-proof and scratch-proof protective film 30 made of silicon resin or the like is formed in advance on the outer surface of the cylindrical body 6. If a photocatalytic film made of titanium dioxide (TiO2) or the like is further formed on the surface of the protective film, natural pollution due to the environment can be reduced.

When this cylindrical sign attachment 1 is attached to a safety fence, a handrail, a roadside pole, a traffic sign post, etc., the retroreflective sheet 28 stands out by reflecting the light of the car at night, and the pedestrian can pass the car. Even when there is no light, light can be emitted from the phosphorescent sheet to recognize the presence of the sign. It is effective in dangerous places with little light at night, such as in mountainous areas.
Further, since the phosphorescent sheet 27 and the retroreflective sheet 28 are hermetically held inside the cylindrical marker attachment 1, deterioration is suppressed and the lifetime as a marker is long.

In the above, several examples have been described.
Although the embodiment has been described mainly with respect to road relations, it is as described above that the present invention is not limited to this.
Although the fixing means has been described by engagement and adhesion, since the pillars and poles are often made of iron, the cylindrical body 6 itself may be formed of a rubber sheet having a magnetic force and attached using magnetic force adsorption. it can. However, in the present invention, the rubber sheet needs to have a shape retaining property to maintain a cylindrical shape. In addition, when the force is insufficient with a single fixing unit, a plurality of types of fixing units are used in combination.
