Description

  The present invention relates to a corner cushion for security, and more particularly to a corner cushion for security used by being attached to a fence or the like surrounding the outer periphery of a construction site.

  For the safety of pedestrians walking around the construction site, a fence is provided around the construction site on the outer periphery. Safety fences are installed at corners and entrances of such fences to prevent injury if pedestrians accidentally collide with them. Such a corner cushion is also used for the purpose of giving a warning display to inform the pedestrian of the presence of a corner portion of the fence in advance.

  For example, Patent Document 1 discloses a corner cushion in which a cushion material is sandwiched between a top sheet member provided with a diagonal vertical stripe warning display pattern and a back sheet member coated with an adhesive. The corner cushion is used by being attached to an attachment object with an adhesive of a back sheet member. Once attached to the object, even if it is peeled off and reused, the adhesive cannot be applied neatly unless the adhesive is applied again to the back sheet member. Therefore, in consideration of labor and cost, such a corner cushion is generally discarded after use.

On the other hand, for example, Patent Document 2 discloses a corner cushion that can be repeatedly mounted using a magnet. A long magnet is attached along both sides of the bag-like cover member, and the cover member is attached to the attachment object by the magnetic force of the magnet. Thereafter, when a foaming agent is injected into the cover member, a corner cushion is formed along the shape of the object to be attached. After use, the cushion material made of the foaming agent is removed from the inside of the cover member, and only the cover member is reused.

  Incidentally, in the corner cushion disclosed in Patent Document 2, the cushion material inside the cover member is discarded after use. Also, the work of taking out the cushion material from the inside of the cover member that has been used for a certain period of time is troublesome.

  The present invention has been made in view of the above situation, and an object thereof is to provide a corner cushion more suitable for repeated use.

  A corner cushion according to the present invention is a corner cushion for security in which a cushion material is sandwiched between a long first cover member and a second cover member, and both side portions of the first cover member and the second cover member. The magnet is intermittently sandwiched between the two along the longitudinal direction.

  According to the corner cushion of the present invention, it is possible to repeatedly attach to the object to be attached, and the attachment and detachment thereof is very easy. In addition, it can be folded and rolled, and is light in weight, so it is very easy to store and transport. Furthermore, since the surface on either side of the first cover member and the second cover member can be used face up, the service life is long.

  A corner cushion for security according to one aspect of the present invention is a corner cushion in which a cushion material is sandwiched between a long first cover member and a second cover member. Such a corner cushion is characterized in that a magnet is intermittently sandwiched between the first cover member and the second cover member along the longitudinal direction on both sides thereof.

  According to this aspect, since the corner cushion is attached to the attachment object by the magnetic force of the magnet, it can be repeatedly attached to the attachment object. Moreover, the attachment / detachment is also easy. Furthermore, since the magnet is intermittently disposed along the long direction of the corner cushion, the corner cushion can be bent at an intermittent portion between the magnets. In other words, the corner cushion can be folded or rolled. Furthermore, the total weight of the magnet can be reduced, and the corner cushion can be easily stored and transported. Further, since the corner cushion can be shipped by being folded or rolled, it can be manufactured and shipped in a long length, and can be cut to a size suitable for an object to be attached at the site. Further, since the magnet is sandwiched between the cover members, it can be used with the front side facing on either side of the first cover member and the second cover member. For example, when the first cover member is used face up and the surface is dirty or damaged, the second cover member can be used face up. In other words, double the service life.

  Moreover, in the said aspect, a magnet is accommodated one each in the bag part which stitched together the 1st cover member and the 2nd cover member. According to this aspect, since the position of each magnet does not shift, it can be firmly fixed to the attachment object. Further, as described above, the corner cushion can be cut and used, so that rainwater or the like easily enters from the cut end. However, even in such a case, water is discharged from the seam hole, so that the inside of the cover member can always be kept dry. In other words, it is possible to prevent a pedestrian who has contacted the corner cushion from getting wet with water accumulated inside the cover member, and to deteriorate the appearance due to dripping water. Moreover, since the air permeability inside the cover member is high due to the stitch holes, the cushion material can always be kept dry. Therefore, it can prevent that the elasticity of a cushion material deteriorates by sucking water. Further, due to the high air permeability inside the cover member, the cover member does not expand or rupture even when the outside air temperature changes. Further, even if the corner cushion is folded or rolled, the air inside the cover member can be easily removed, so that it is easy to make it compact.

  Furthermore, in the said aspect, a warning display pattern can be given to the cover part of a 1st cover member and a 2nd cover member, and a warning display can be performed by making each surface face up. Further, when different types of warning display patterns are given to the front and back cover portions of the first and second cover members, warning indications can be made according to the place of use simply by changing the orientation of the front and back sides. That is, it is not necessary to stock many types of corner cushions.

  Moreover, in the said aspect, the warning display pattern of a cover part is given by gravure printing. According to this aspect, it is possible to provide a warning display pattern with good color development, that is, a warning display pattern having a high effect of calling attention to a pedestrian, and a long corner cushion can be provided at low cost.

  Further, in the above aspect, the cushion material is made of a non-water-absorbing elastic material. According to this, even if water enters the inside of the cover member, the cushion member soaks and does not stay so that the inside of the cover member can be quickly dried. In such an embodiment, the non-water-absorbing elastic material is preferably made of a bubble cushioning material in which bubbles are confined between non-water-absorbing sheet materials. Since the foam cushioning material is easy to bend and does not lose its elasticity even if it is repeatedly folded, it does not deteriorate even if the corner cushion is repeatedly used and folded.

  Next, one embodiment according to the present invention will be described in detail with reference to FIGS.

  As shown in FIG. 1, the corner cushion 10 is formed by a magnet 3 at a corner of a steel fence 5 that surrounds the outer periphery of a construction site with either the first cover member 1 or the second cover member 2 facing up. Used detachably.

  As shown in FIGS. 2 and 3, the corner cushion 10 has a magnet 3, a series of long or predetermined lengths between the first cover member 1 and the second cover member 2 provided with a warning display pattern 6 on the surface. The cushion material 4 is sandwiched and sewn. In the following, the longitudinal direction of the corner cushion 10 is simply referred to as “long direction”, and the direction perpendicular to the long direction is simply referred to as “width direction”.

  Specifically, the first cover member 1 and the second cover member 2 are made of a non-water-absorbing sheet material having a high tear strength. For example, a tarpaulin having a composite structure in which fibers are sandwiched between synthetic resins such as soft vinyl chloride resin. It consists of the following sheet materials. The materials of the first cover member 1 and the second cover member 2 are selected so as not to be turned up or fluttered by the wind. The 1st cover member 1 and the 2nd cover member 2 are strip | belt-shaped sheets, The warning display pattern 6 which alerts a pedestrian is given to the surface 1a and 2a. For example, the warning display pattern 6 is an oblique vertical stripe pattern in which two arbitrary colors such as yellow and black and green and white are combined. Such a color warning display pattern 6 is preferable because high color development can be obtained by gravure printing.

  Here, if different warning display patterns 6 are given to the front cover surfaces 1a and 2a of the first cover member 1 and the second cover member 2, the user can select which surface to use in the front direction. That is, even if the two corner cushions 10 having the respective warning display patterns 6 are not held, the two types of warning display patterns 6 can be displayed only by holding such one corner cushion 10. Thereby, the number of stocks of the corner cushion 10 can be reduced.

  Moreover, you may give the same warning display pattern 6 to each of the surface mounting surfaces 1a and 2a of the 1st cover member 1 and the 2nd cover member 2. FIG. For example, while using one of the front surfaces 1a (or 2a) facing the front, dirt, scratches, or damage may occur, which may affect alerting to pedestrians. In some cases, it may cause problems in appearance. Even in such a case, it can be turned over and used with the other surface 2a (or 1a) facing up. That is, the life of the corner cushion 10 is extended more than doubled.

  The magnet 3 is intermittently arranged at intervals along both sides of the cover members (1, 2). In other words, the cover members (1, 2) are arranged in the longitudinal direction so as to be separated from each other in the width direction. The magnet 3 is a ferrite magnet, but a samarium cobalt magnet, a neodymium magnet, or the like may be used so as to increase the attractive force to the attachment target.

  The cushion material 4 is arrange | positioned along the elongate direction in the center part of the width direction. The cushion material 4 is a non-water-absorbing elastic material, and is a bubble cushioning material in which bubbles are confined between non-water-absorbing sheet materials such as polyethylene. The foam cushioning material is easy to bend and can retain the cushioning performance for a long time even when it is repeatedly folded.

  As shown in FIGS. 4 and 5, the cover members (1, 2) sandwiching the magnet 3 and the cushion material 4 are not water-absorbing along the seam 7a along the width direction and the seam 7b along the length direction. Is sewn with a strong thread. The seams (7a, 7b) are provided so as to surround the magnet 3 and the cushion material 4 one by one. That is, the magnet 3 and the cushion material 4 are accommodated in the bag portion 8 formed by sewing the cover members (1, 2), and these do not move greatly. Further, a series of long cushion materials 4 may be sewn together with the cover members (1, 2) at the seams (7a, 7b), and in this case, the cushion material 4 does not move.

  Next, a method for providing the corner cushion 10 will be described in detail with reference to FIGS. 4 and 6 to 8.

  As shown in FIG. 6, the corner cushion 10 is manufactured in a long shape and is provided in a folded state.

  As shown in FIG. 4, the corner cushion 10 can be folded in the longitudinal direction at the intermittent portion 9 between the magnets 3 arranged in a row. That is, in the fold including the intermittent portions 9 on both sides in the width direction as shown in FIG. 7B or 7C from the state of being elongated in the longitudinal direction as shown in FIG. It can be bent in the direction of the scale.

  Here, as shown in FIG. 7B, if the length X of the intermittent portion 9 of the first cover member 1 arranged on the outer peripheral side of the fold is longer than (2T + 2t), the corner cushion 10 can be completely folded. Is possible. Here, T is the thickness of the magnet 3, and t is the thickness of the cover member 2. The same applies even when the second cover member 2 is disposed on the outer peripheral side of the fold.

  On the other hand, as shown in FIG. 7C, if the length X is shorter than (2T + 2t), the corner cushion 10 cannot be completely folded. In that case, it can be provided in a rolled state as shown in FIG.

  7B and 7C, the corner cushion 10 has air permeability between the inside and the outside through the holes of the seams (7a, 7b). Since the air in the part 8 is easily removed, it is easy to be compact.

  In addition, since the cushion material 4 is made of a bubble cushioning material, even if the corner cushion 10 is folded or wound small, or repeated for reuse, the elastic force does not deteriorate.

  As described above, the corner cushion 10 provided by being folded can be used by being adjusted to a length suitable for the attachment object by cutting in the width direction at the intermittent portion 9 of the magnet 3. For example, as shown in FIG. 4, it is preferable to cut at the intermittent portion 9 because it can be easily cut. That is, in the intermittent part 9 between the magnets 3 adjacent to each other in the longitudinal direction, two seams 7a are arranged in parallel at intervals, and when this is cut at the cutting allowance 11a therebetween, the seam 7a Therefore, the bag portion 8 containing the magnet 3 is not opened, and the magnet 3 does not fall off. Similarly, when this is cut at the cutting margin 11b between the two seams 7a between the adjacent cushion materials 4, the cushion material 4 does not fall off.

  In the cut corner cushion 10, any one of the front surfaces 1a and 2a provided with the warning display pattern 6 is selected as the display surface. As shown in FIG. 1, the corner cushion 10 is applied so as to cover the corner portion with the other surface of the display surface facing the corner portion of the fence 5 to be attached, and is closely attached to the corner portion. The corner cushion 10 is attached by adsorbing both side parts to a flat part beside the corner part of the object to be attached by the magnetic force of the magnets 3 arranged on both side parts.

  Here, if the corner cushion 10 is lifted from the fence 5 to be attached, it is not preferable in terms of appearance and detachment, but if the cushion material 4 is a bubble cushioning material, the corner cushion 10 can be closely adhered along the shape of the attachment object. This can be prevented.

  Further, the corner cushion 10 is covered with the cover member (1, 2) and the cushion material 4 and the magnet 3 so that the intermittent portion 9 is not turned up or fluttered by the wind or can be folded or wound. The dimensions and arrangement are adjusted as appropriate.

  The corner cushion 10 attached to the fence 5 to be attached may be exposed to rain. However, even if water enters the bag portion 8 of the cover member (1, 2), the water is quickly discharged from the holes of the seams (7a, 7b), so the inside of the bag portion 8 is easily dried. Further, since the cushion material 4 is a non-water-absorbing elastic material, it does not stay even if water enters. Furthermore, since the air permeability inside and outside of the corner cushion 10 is enhanced through the holes of the seams (7a, 7b), the inside thereof is quickly dried. The air in the bag portion 8 does not expand or rupture due to the difference in temperature between the outside air temperatures.

  The used corner cushion 10 is removed from the fence 5 or the like to be attached. Since the corner cushion 10 is detachably attached by magnetic force, the removal is easy. The removed corner cushion 10 is folded or rolled up so as to be easily transported and stored, transported and stored in a storage location, and transported to the next use location. In addition, the corner cushion 10 can be transported or stored while being stretched as appropriate.

  The corner cushion 10 transported to the next use place is attached to the fence 5 to be attached again by the magnetic force of the magnet 3. Since the cushion material 4 is made of a foam cushioning material, the cushioning performance change is small even if it is repeatedly folded, and it hardly deteriorates even if it is repeatedly used.

  Although exemplary embodiments according to the present invention have been described above, the present invention is not necessarily limited thereto, and those skilled in the art will recognize various alternative embodiments and various embodiments without departing from the scope of the appended claims. Modifications could be found.
