Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step eliminating material. For more details, steps in the room such as sills and floors,
Alternatively, steps outside the building, such as between the road and the site of the building,
The present invention relates to a step-eliminating material that is continuous on a smoothly inclined surface.

[0002]

2. Description of the Related Art Conventionally, a step-eliminating material having a triangular prism shape having a bottom surface, an inclined surface formed at an acute angle to the bottom surface, and a vertical surface perpendicular to the bottom surface has been used. This is used, for example, by arranging it on a step between the sill and the floor so that the vertical surface is in contact with the side of the sill protruding from the floor. Thereby, a smooth continuous surface is formed from the floor surface to the upper surface of the sill, and a pedestrian is prevented from tripping on the side surface of the sill protruding from the floor surface, thereby facilitating the passage of a wheelchair.

[0003]

The size of steps such as floors and sills are different from each other. For this reason, conventionally, it is necessary for producers and distributors to produce step-eliminating materials of various sizes having different heights and manage the stock. Further, for the user, it is necessary to check the size of the step in advance and select and purchase a step-eliminating material having a required height in accordance with the size.

[0004] The present invention provides a step-eliminating material that can easily cope with two or more height steps with one step-eliminating material, and minimizes the above-mentioned inconveniences of producers, distributors and consumers. It is a technical task to do so.

[0005]

The step-eliminating material of the present invention comprises:
It has a triangular prism shape having a bottom surface, an inclined surface formed at an acute angle with respect to the bottom surface, and a vertical surface substantially perpendicular to the bottom surface, and parallel to any one of the bottom surface, the inclined surface, and the vertical surface. It is characterized in that a separating surface which is easy to separate or cut is provided. It is preferable that such a step eliminating material is integrally formed as a long material by extrusion molding of a thermoplastic resin and cut into a predetermined length.
In that case, a part of the separation surface can be a release surface that is joined by pressure immediately after extrusion and before cooling.

When the separation surface is parallel to the vertical surface, at least a part of the separation surface can be constituted by a slit provided with some thickness left from the bottom surface and the inclined surface. . Further, it is preferable that the surface layer portion and the other portion of the inclined surface are made of thermoplastic resin of different materials, and both are integrally formed by co-extrusion. In that case, it is preferable to form a slit that forms a part of the separation surface parallel to the vertical surface, leaving the vicinity of the bottom surface in another part, and join the remaining separation surface near the bottom with a peeling surface. Further, it is more preferable to form a concave groove or a ridge on an extension of the separation surface (especially a slit) on the surface of the inclined surface or the bottom surface.

[0007]

The step-eliminating material of the present invention can be used as it is, in which case the bottom surface is placed on a floor or the like and the vertical surface is brought into contact with the step portion. . When the height of the step portion is low, the step eliminating material is separated at the separation surface. As a result, the step-eliminating material is separated into a triangular prism-like portion having a similar cross-sectional shape to the original step-eliminating material, and the remaining trapezoidal column. Therefore, a similar triangular prism-shaped portion or trapezoidal portion can be used as a step-eliminating material corresponding to a low step. When a large number of separation surfaces are formed, it is possible to correspond to steps having various heights according to the number.

When the step eliminating material is integrally formed as a long material by extrusion molding of a thermoplastic resin and cut into a predetermined length, mass production of the step eliminating material is easy. In the case where a part of the separation surface is formed as a peeled surface joined by pressure immediately after extrusion molding and before cooling, the peeled surface can be easily separated. When the separation surface is parallel to the vertical surface, when at least a part of the separation surface is constituted by a slit provided with some thickness left relative to the bottom surface and the inclined surface, a portion of the slit is provided. Are separated in advance, so that separation on the separation surface is further facilitated. In addition, since the slit is perpendicular to the bottom surface, it can sufficiently support the force applied from above.

Further, when the surface portion of the inclined surface and the other portion are made of thermoplastic resin of different materials and both are integrally formed by co-extrusion molding, the color of the inclined surface exposed to the outside,
It can be easily manufactured in various external forms depending on the condition of the place of use with respect to the pattern, the texture, the difficulty of sliding, and the like.
In addition, when forming a slit that constitutes a part of the separation surface parallel to the vertical surface leaving the vicinity of the bottom surface in the other part, when the remaining separation surface near the bottom is joined by a peeling surface, the separation surface is used. Separation is easier. In the case where a concave groove (especially a V-groove) or a ridge is provided on the inclined surface or an extension of the separation surface at the bottom, the groove serves as a guide for cutting with a cutter or the like, so that separation on the separation surface is easier. . In addition, since these grooves and ridges act to prevent slipping, when they are installed on a floor or the like, they are difficult to slip even when stepped on with a foot or the like, and the step-eliminating material is hard to move.

FIG. 6 is an end view showing another embodiment.
b and 6c are end views showing a method of using the step eliminating material, and FIG. 7 is an end view showing still another embodiment of the step eliminating material of the present invention.

The step-eliminating material A shown in FIGS. 1 and 2 has a triangular prism shape having a bottom surface 1, an inclined surface 2 having an acute angle to the bottom surface, and a vertical surface 3 substantially perpendicular to the bottom surface 1. Is presented. The vertical surface 3 is provided inside the step eliminating material A.
Are formed substantially parallel to the bottom surface 1 (perpendicular to the bottom surface 1), leaving some thick portions 5, 6 with respect to the bottom surface 1 and the inclined surface 2, respectively. .
The step-eliminating material A can be manufactured from, for example, a soft or hard thermoplastic resin, and can be easily manufactured by being integrally formed as a long material by extrusion molding, and cutting into a predetermined length. Further, in the present embodiment, the surface layer 7 and the other portion 8 constituting the thick portion 6 of the inclined surface 2 are made of thermoplastic resin of different materials, and both are integrally formed by co-extrusion.

The size of the step eliminating material A varies depending on the size of the step portion to be used, the place where the step is used, and the like. For example, the height of the vertical surface 3 is usually 10 to 80 mm in accordance with the height at which a stumble easily occurs. About 20 to 40 mm is preferable. The angle of the inclined surface 2 is about 10 to 35 degrees, especially 1
About 5 to 25 degrees is preferable. The number of slits 4 is not particularly limited, but is preferably 1 to 8, particularly preferably 3 to 6. The width of the slit 4 is preferably about 0.5 to 3 mm, particularly preferably about 1 to 2 mm. The thickness of the portion 9 between the slits 4 is preferably about 3 to 15 mm, particularly preferably about 5 to 10 mm. It is preferable that the thickness of the surface layer 7 is about 0.5 to 1 mm, and the thick part 5 on the bottom side is about 2 to 3 mm, because it is easy to cut and has sufficient strength.

The material of the step-eliminating material A is not particularly limited as long as the thick portions 5 and 6 can be cut easily, and it is used at a place of use, for example, indoor or outdoor. What is necessary is just to select according to riding weight etc. As the material, for example, polyethylene, polypropylene,
Solids and foams of various thermoplastics, such as polyvinyl chloride, are used. It is also possible to use thermoplastic elastomers or solid or foamed natural or synthetic rubbers. The hardness of the step difference canceling material A is, for example, HA50
About HA100, particularly preferably about HA75 to HA90.

When the surface layer 7 of the inclined surface 2 is formed of a material different from that of the other parts 8 as shown in FIG. 2, a good-looking material having colors and patterns is used for the surface layer 7 appearing outside. The use of a material reclaimed from waste plastic or the like for the other portions 8 helps both the appearance and the environmental protection. In that case, the pigment is mixed into the material of the surface layer portion 7 and extruded to form a wood grain pattern P as shown in FIG.
May be formed. Further, if wood powder is mixed into the material of the surface layer portion 7, a woody texture can be obtained, and therefore, it is preferable to use it for a step portion on the floor of a flooring or the like. Further, in the case of using for a step portion of a tile or a stone of an entrance or an external structure, a coloring / pattern of the system may be provided. Further, the surface layer portion 7 may be made a conspicuous color such as red or yellow so that the position of the step difference canceling material A can be easily understood.

In the step difference eliminating material A shown in FIG. 2, one end 7a of the surface layer portion 7 is folded back to the bottom surface 1 side. Therefore, the sharp tip is protected. Furthermore, a slit 4 is formed on the surface of the surface layer 7.
Is formed in the longitudinal direction. V groove 1
The depth of 0 may be about 0.3 to 0.8 mm. Those V
Since the groove 10 serves as a guide when the surface layer 7 is cut by a cutter or the like, the cutting operation is facilitated. It also has the effect of preventing the feet from slipping. Further, in the step difference eliminating material A,
A large number of V-grooves 11 extending in the longitudinal direction are formed on substantially the entire bottom surface 1. The V-grooves 11 on the bottom surface 1 serve as non-slip when the step eliminating material A is placed on the floor surface.

In the step-eliminating material A shown in FIG.
A so-called peeling surface 4b is formed below the inner surface 4a on the distal end side of the substrate. The release surface 4b is obtained by molding in a state of being separated at the time of extrusion molding, and pressing and joining immediately after being released from the mold and before cooling. Such a peeled surface 4b can be relatively easily separated. In the present embodiment, the inner surface 4a on the distal end side of the slit 4 and the extension surfaces above and below are the separation surfaces in the first aspect.

On the other hand, in the step-eliminating material A shown in FIG. 3, the ridges 12 corresponding to the slits 4 are formed on the bottom surface 1 in the longitudinal direction. The protruding ridge 12 matches the rising surface 12 a on the vertical surface side with the inner surface 4 a on the distal end side of the slit 4. Therefore, it can be easily cut from the bottom surface 1 side by a cutter or the like while using the rising surface 12a as a guide.

The step eliminating material A configured as described above is
As shown in FIG. 4A, the step between the two floors can be eliminated by arranging them between the floor surfaces 14 and 15 having the same shape and the height difference. At this time, the vertical surface 3 is brought into contact with the side surface 16 of the higher floor surface (or sill, etc.) 15, and the bottom surface 1 is placed on the lower floor surface 14. In that case, the bottom surface 1
Is preferably fixed with double-sided tape because it does not move.
In the case of the above arrangement, a vertical force is applied to the portion 9 between the slits 4, 4, so that the weight can be sufficiently supported. Further, since the vertical surface 3 is in contact with the side surface 16, there is almost no bending in the horizontal direction. The space between the vertical surface 3 and the side surface 16 may be fixed with double-sided tape.

If the step is smaller than the above case, as shown in FIG. 4B, for example, when the upper and lower thick portions 5 and 6 of the second slit 4 are cut off with a cutter or the like, a surface corresponding to a vertical surface is formed. A newly formed step-eliminating material A1 having a similar shape and a low height is obtained. In addition, by installing between the low floor surface 14 and the high floor surface 15 in the same manner as described above, the step between them can be eliminated. The upper thick portion 6 can be easily cut using the V-groove 10 in FIG. The lower thick portion 5 is preferably cut by using the inner surface (lower side) 4a of the slit 4 as a guide, because it is easy to cut and the newly obtained vertical surface 3a becomes flat. In the case of the separation surface 4b as shown in FIG. 2, the separation surface 4b can be easily separated by peeling.

For a lower step, the thick portions 5 and 6 are cut along the slit 4 corresponding to the lower portion as shown in FIG. 4C. As a result, a similar step removing material A2 having a lower vertical surface 3a is obtained. As described above, in the above-described step difference eliminating material A, by selecting an appropriate slit 4 and cutting it, it is possible to adapt to various steps. Moreover, since the thick portions 5 and 6 can be separated only by cutting, the cutting operation is simple.

FIGS. 5a and 5b show another use of the above-described step relief material A. FIG. In this case, the cutting position of the thick portion 5 below the slit 4 is the same as that described above, but as shown in FIG. 5a, the upper portion is cut with some surface layer 7 left. Then, as shown in FIG. 5B, the remaining surface layer portion 7 is put on the higher floor surface 15 and joined with a double-sided tape or the like. This is more preferable because the inclined surface 2 and the floor surface 15 smoothly continue.

When the step-eliminating material A is cut at the slits 4 as described above, the height of the vertical surface 3 can be changed step by step, but if there is some difference depending on the size of the step, There is. Since such a difference hardly causes a stumbling, it may be ignored. However, as shown in FIG. 5B, when the surface layer 7 is connected to the higher floor surface 15, the difference is further reduced, and the appearance is improved. Good.

The step-eliminating member B shown in FIG. 6A has a plurality of separation surfaces 20 parallel to the bottom surface 1. The separation surface 20 may be any surface that can be easily cut or peeled.
It is preferable to use the same release surface as the release surface 4b in the embodiment. This can be used as it is, and depending on the height of the step, for example, as shown in FIG. 6b, the upper triangular prism portion 21 is removed, and only the lower trapezoidal portion 22 is removed. It can be used as a step eliminating material. Conversely, as shown in FIG. 6C, the trapezoidal portion 23 on the lower surface side can be removed, and the upper triangular prism-shaped portion 24 can be used as a step difference canceling material.

6A, the thickness of the upper layer (for example, two or three layers) and the thickness of the lower layer may be changed. In that case, fine height adjustment for the height of the step is possible. For example, when the upper layer has a thickness of 5 mm and the lower layer has a thickness of 7.5 mm, the height can be adjusted at a pitch of approximately 2.5 mm.

Further, the surface eliminating portion B similar to that shown in FIG. 2 may be provided also for the step difference eliminating material B shown in FIG. 6A. In that case, the color of the portion other than the surface layer portion 7 may be made a conspicuous color such as red or yellow. In the case of such a step removing material B, in the case of the usage shown in FIG. 6B, since the conspicuous color appears outside, it has a function of displaying the position of the step to a person passing over the step removing material B. . On the other hand, in the case of the use method shown in FIG. 6C, it can be used while leaving the surface layer 7 such as a grain pattern.

The step eliminating material C shown in FIG. 7 has a plurality of separation surfaces 20 parallel to the inclined surface 2. This separation surface 20 can be a peeling surface, similarly to the step difference canceling material B in FIG. 6A. This can also correspond to various steps.

In the above embodiment, the step-eliminating material manufactured by co-extrusion was shown. However, the step-eliminating material of the present invention is not limited to these. For example, the surface layer 7 and other comb-like parts may be combined. It may be manufactured separately and then joined by an adhesive or welding. Furthermore, it can also be manufactured by injection molding or other manufacturing methods. A surface layer made of a different material may be provided not only on the inclined surface but also on the bottom surface. Further, in the above-described embodiment, the case where the step-eliminating material A is bonded to the floor surface with the double-sided tape has been described.
A double-sided tape or an adhesive layer may be provided on the bottom surface or the like, and a release paper may be placed thereon. The step-eliminating material may be firmly fixed to the floor using fixing means such as nails, screws, bolts, or the like.

The direction of the separation surface in the step-eliminating material of the present invention may be parallel to any one of the bottom surface, the inclined surface and the vertical surface as described above. However, since the angle of the inclined surface is usually 45 degrees or less as in the case of the material A for eliminating the step difference in FIGS. 1 and 2, providing the separation surfaces perpendicularly to the bottom surface increases the distance between the separation surfaces, and the extrusion molding is not performed. It will be easier.
