Description

  The present invention relates to a staircase covering a tread surface and a kick-up surface of a staircase and a staircase covered with the staircase floor material.

  When rainwater or cleaning water flows down the surface of stairs, especially outdoor stairs, dirt and dirt that accumulates on the surface of the stairs flow down with the water. There is a problem of lowering.

  In order to cope with such a problem, in a staircase in which the kicking surface is covered with a synthetic resin or synthetic rubber coating material from the tread surface, it extends in the lateral direction on the surface of the front hanging portion of the coating material covering the kicking surface. It has been proposed to integrally form draining protrusions (see, for example, Patent Document 1).

JP 2007-56549 A

  However, in the floor material for stairs of the above-mentioned patent document 1, since the draining protrusions are only provided uniformly across the lateral direction of the stairs, the water becomes sparse and flows down the entire kick-up surface. Since the amount of water per drained part will be reduced, the water will not cut out sufficiently, especially when the bottom surface of the draining protrusion is horizontal or when the amount of water flowing down the kicking surface is small. There was a problem that the wind ran around to the lower side of the draining protrusion, and the water contaminated the stairs along the kicking surface.

  The present invention has been made in view of the above problems, and the problem to be solved is that even when the amount of water flowing down is small, water can be drained appropriately, and streaks are formed on the raised surface of the stairs or the front drooping portion. An object of the present invention is to provide a staircase that does not cause dirt and a staircase covered with the staircase.

In order to achieve the above object, a floor material for stairs according to the present invention is a floor material for stairs that covers a tread surface and a kick-up surface of a staircase, and a tread surface portion that covers all or a part of the tread surface of the stairs. , Consisting of a front hanging part that covers part or all of the raised surface of the stairs,
In the vicinity of the corner portion where the tread surface portion and the front drooping portion intersect, a plurality of build-up portions extending from the tread surface portion to the front drooping portion are provided at intervals, and in the vertical groove formed between the plurality of build-up portions, At least a part thereof is in the groove, and a draining projection is provided across the groove.

  In the floor material for a staircase of the present invention, the vertical cross-sectional shape of the draining protrusion is a substantially triangular shape of a front descending front end protruding forward, and the draining protrusion is provided at the lower end of the groove. preferable. In particular, a floor material for stairs in which the tip of the draining protrusion is located below the lower end of the built-up portion is preferable.

  Next, a staircase coated with a staircase material according to the present invention is characterized in that any one of the above staircase materials covers the tread surface and the kick-up surface of the staircase.

  The floor material for stairs of the present invention is provided with a plurality of built-up portions extending from the tread surface portion to the front sag portion in the vicinity of the corner portion where the tread surface portion and the front sag portion intersect, A longitudinal groove on the side of the front hanging portion that communicates is formed. For this reason, rainwater and cleaning water that has fallen on the tread surface of the staircase floor material, or water that has flowed down from the upper tread surface is temporarily blocked by the built-up portion on the tread surface side and formed between the built-up portions. Water is collected and flows into the horizontal grooves. In this way, since the water on the tread surface is collected in the horizontal groove, the amount of water flowing down the vertical groove is much larger than when there is no overlay, and the flowing water is interrupted. Less. Therefore, the draining protrusions provided in the vertical grooves between the built-up parts make it easy to drain water, and it is difficult for water droplets to adhere to the draining protrusions. There is no streak of dirt on the front drooping part or the kicking surface of the stairs. In addition, since the draining projection is provided in the groove, even if the tip of the draining projection protrudes slightly from the overlay, the majority of the draining projection is in the groove, and a pedestrian may hit his foot or hit a load. However, since most of them are protected by the overlay and are not easily damaged, there is little fear of losing the draining function.

Further, the vertical cross-sectional shape of the draining protrusion is a substantially triangular shape before and after the tip protrudes forward, and the flooring material for the staircase provided with the draining protrusion at the lower end portion of the groove has a draining protrusion, By providing it at the lower end of the vertical groove formed by the built-up part, turbulent flow is settled and water with a stable flow reaches the draining protrusion, and the vertical sectional shape of the draining protrusion is By making the front and descending approximately triangular shape, when the water flowing down flows through the inclined front surface of the draining protrusion, it flows in a state where a forward moment is given, so that the draining protrusion does not wrap around the lower surface of the draining protrusion. Since it tends to fall slightly forward from the front end (lower end of the front surface), there is an advantage that the draining performance is further improved.
Note that the lower end portion of the vertical groove means a portion below the boundary line when the vertical groove is bisected in the height direction.

  Further, the staircase floor material in which the tip of the draining protrusion is located below the lower end of the built-up portion is such that the amount of water is particularly small and water does not fall easily from the draining protrusion. Even if the water drops temporarily and become water droplets, the water droplets will not spread across the tip of the draining protrusion due to the influence of surface tension or wind. It is possible to reliably prevent streaks from adhering to the surface.

  Next, the staircase covered with the staircase floor material of the present invention covers the staircase with the staircase floor material that exhibits the above-described excellent effects, thereby raising the front hanging portion of the staircase floor material or the stairs. There is no loss of aesthetics due to streaks on the surface.

It is a perspective view which shows the floor material for stairs which concerns on one Embodiment of this invention. It is principal part explanatory drawing of the floor material for stairs. It is an enlarged view of the draining protrusion which comprises the floor material for stairs. It is a schematic perspective view which shows the stairs covered with the floor material for stairs which concerns on one Embodiment of this invention. It is a partial front view which shows the floor material for stairs concerning other embodiment of this invention. It is principal part explanatory drawing of the floor material for stairs which concerns on further another embodiment of this invention.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

The staircase flooring 1 of the present invention shown in FIG. 1 is made of a synthetic resin such as soft vinyl chloride resin or polyolefin resin, synthetic rubber, or the like. As shown in FIG. Used to cover the surface of the kick-up surface S3. The floor material 1 for stairs includes a tread surface portion 2 that covers the tread surface S2 of the staircase S and a front hanging portion 3 that covers an upper portion of the raised surface S3 of the staircase S. The tread surface portion 2 and the front drooping portion 3 intersect. In the vicinity of the corner portion 4, a plurality of substantially L-shaped built-up portions 5 extending from the tread surface portion 2 to the front drooping portion 3 are provided in the lateral direction with a certain interval. Thus, by providing the built-up portions 5 with an interval, a groove 6 is formed between the built-up portions 5 and 5, and the draining protrusion 7 is formed at the lower end of the vertical structure 6 b of the groove 6. Is provided.
In this embodiment, the entire tread surface S2 is covered with the tread surface portion 2, but only a part of the tread surface S2, that is, the front side in the vicinity of the corner portion 4 may be covered. You may make it coat | cover only a part of. Similarly, the kick-up surface S3 may be covered not only on the upper portion in the vicinity of the corner portion 4, but also on the entire surface.

  As shown in FIG. 1, a number of anti-slip protrusions 8 and a plurality of anti-slip ridges 9 are provided on the surface of the tread surface 2 of the staircase floor material 1 to prevent slipping. The anti-slip protrusions 8 are provided so that the number on the near side that is often stepped on when ascending and descending the stairs is large and the number on the back side is small. Further, the anti-slip ridges 9 are provided in the lateral direction in the vicinity of the built-up portion 5 (the ridges 9 are not provided continuously in the horizontal direction but are intermittent in consideration of drainage of the tread portion 2. Is provided). Thus, by providing a large number of anti-slip protrusions 8 and a plurality of anti-slip ridges 9 on the surface of the tread portion 2, rainwater is retained by the action of the built-up portion 5, and water is accumulated in the tread portion 2. Even if it becomes, the foot of the pedestrian is supported by the anti-slip protrusion 8 and the anti-slip ridge 9, and the foot is not directly immersed in the water pool, which may cause unpleasant phenomena such as water wetting and water splashing. In addition, the physical anti-slip effect can prevent stairs accidents even on rainy days.

  In the case where a forward water gradient is applied to the tread surface S2 of the staircase S, the tread surface portion 2 is simply bonded and fixed to the tread surface S2 of the staircase S so that the forward water gradient is provided. Can be secured. Further, when a forward water gradient is not applied to the tread surface S2 of the stairs S, the water gradient may be applied by forming the thickness so that the tread surface portion 2 is directed forward. The tread surface portion 2 of the staircase flooring 1 having such a configuration most preferably covers the entire tread surface S2 of the staircase S, but excludes a mode of covering only a portion of the tread surface S2 close to the kicked surface S3. It is not a thing.

Next, as shown in FIG. 4, the front hanging portion 3 of the staircase floor material 1 covers an upper portion of the kicking surface S3 of the staircase S. Specifically, from the upper end of the kicking surface S3 of the staircase S. It covers up to about 20 to 100 mm (40 mm in this embodiment) downward.
In the present embodiment, only the upper part of the kicking surface S3 of the staircase S is covered. As described above, the front hanging portion 3 is extended downward to cover the entire kicking surface S3 of the staircase S. It may be. Further, the stepped surface portion 2 of the lower staircase flooring 1 is extended rearward and raised along the kicked surface S3, so that the raised surface S3 (lower portion) of the staircase S not covered by the front hanging portion 3 is formed. You may make it coat | cover. In this case, the front end portion 3 of the upper staircase flooring 1 is overlapped and covered on the front end of the extended lower tread surface portion 2 from above, so that the front end of the tread surface portion 2 is separated from the kicked surface S3 of the staircase S. It is good to prevent this.

  In the corner portion 4 where the tread surface portion 2 and the front drooping portion 3 intersect, as shown in FIG. 1, a plurality of built-up portions 5 are regularly spaced in the lateral direction of the staircase flooring 1. Is provided. In this way, by providing a plurality of built-up portions 5 with a certain interval, a single groove 6 (a horizontal groove 6a and a vertical groove 6b) is provided between the two built-up portions 5 and 5. ) Is formed. This build-up portion 5 is provided so that water flowing from the tread surface portion 2 to the front drooping portion 3 is temporarily blocked and can be reliably guided into the groove 6 formed between the build-up portions 5 and 5. is there. Therefore, if the height (wall thickness) of the built-up portion 5 is lower than 1 mm, water will not be properly blocked by the built-up portion 5 and may pass through the surface of the built-up portion 5 or once into the groove 6. Since the collected water may flow out of the groove 6, it is not preferable. In addition, if the height (wall thickness) of the built-up portion 5 is about 5 mm, it is sufficient for the damming effect, and conversely, if it is 5 mm or more, there is a risk that a person may crawl when the staircase S is raised or lowered. It is preferable that the built-up part 5 is built up about 1-5 mm from the surface of the tread part 2 and the front drooping part 3, and the thickness of embodiment is 2 mm. When the built-up portion 5 is within the above range, the water that flows from the tread surface portion 2 to the front drooping portion 3 can be reliably guided into the groove 6 without interfering with walking. There is no worry of spilling out of the groove 6.

  Further, the build-up portion 5 must be provided continuously from the tread surface portion 2 to the front drooping portion 3, and even if provided only on the tread surface portion 2 or only the front drooping portion 3, the draining projection 7 described later properly drains water. Since this is not possible, the problem to be solved by the present invention cannot be achieved. That is, even if the build-up portion 5 is provided only on the tread surface portion 2, once collected water spreads and flows down the front drooping portion 3, it does not make sense to provide the build-up portion 5. Moreover, when the build-up part 5 is provided only in the front drooping part 3 (including provision in the middle of the front drooping part 3), the water flowing according to the water gradient of the tread part 2 flows into the groove 6 and the build-up part 5 As a result, the streaks of water that have flowed down the surface of the built-up portion 5 adhere to the raised surface S3 of the staircase S. Therefore, it is necessary to provide the built-up portion 5 continuously from the tread surface portion 2 to the front hanging portion 3.

The build-up part 5 and the groove 6 are preferably provided uniformly over the width of the staircase flooring 1, and the width of the groove 6 with respect to the width of the staircase flooring 1 (interval between the build-up parts 5 and 5). When the total ratio is about 10 to 30% (17.5% in the embodiment), water is guided into the groove 6 even when the amount of water is small, and water overflows from the groove 6 even when the amount of water is large. There is nothing. Considering these, it is preferable that the interval between the built-up portions 5 and 5, that is, the lateral width of the groove 6 is about 1 to 10 mm, and the lateral width of the built-up portion 5 is about 10 to 100 mm. Then, water can be appropriately guided into the groove 6 to smoothly flow through the groove 6.
In the embodiment, the lateral width of the groove 6 is 5 mm, and the lateral width of the built-up portion 5 is 47 mm.

  Moreover, the depth dimension (depth dimension of the horizontal groove 6a) on the tread surface 2 side and the vertical dimension (vertical dimension of the longitudinal groove 6b) on the front hanging part 3 side are short. If too much water flows into the groove 6 at one time, the water may overflow from the groove 6, so that the depth of the build-up part 5 on the tread surface part 2 side is 10 to 50 mm, the front drooping part 3 side In this embodiment, the depth of the built-up part 5 on the tread surface 2 side is 25 mm, and the vertical dimension of the built-up part 5 on the front drooping part 3 side ( (Including draining protrusions) is formed to be 20 mm. By setting the build-up portion 5 to such a size, when the collected water flows in the groove 6 (particularly in the longitudinal groove 6b), the turbulent flow is settled and the water flow can be stabilized. .

In addition to the effects described above, the built-up portion 5 having the above-described configuration is provided at the corner portion 4 where the durability of the staircase flooring 1 is most required, so that the durability of the staircase flooring 1 is improved. Also contributes.
As described above, instead of providing the build-up portion 5 by building up the surfaces of the tread surface portion 2 and the front drooping portion 3, the surface of the tread surface portion 2 and the front drooping portion 3 is provided with a recessed groove so that the surrounding thickness is increased. You may form the build-up part 5 by making it thin. Further, as described above, the built-up portion 5 may be built up and a recessed groove may be provided between the built-up portions 5 and 5.
Further, the build-up portion 5 does not need to be formed integrally with the tread surface portion 2 and the front drooping portion 3, and is formed as a separate, substantially L-shaped build-up portion 5 with an adhesive or the like. The part 3 may be adhered and fixed.

As shown in FIGS. 1 and 2, a draining protrusion 7 crosses the vertical groove 6b at the lower end of the vertical groove 6b on the front drooping part 3 side formed between the build-up parts 5 and 5. It is provided as follows. The draining protrusion 7 does not have to be entirely in the vertical groove 6b, but at least its starting point P is the vertical groove 6b so that the water flowing down the vertical groove 6b can be drained reliably. It is necessary to provide so that it may be located inside.
Note that the lower end portion of the longitudinal groove 6b is a broad concept indicating a lower portion than a boundary line when the longitudinal groove 6b is equally divided in the height direction. Thus, it is preferable that the draining protrusion 7 is provided as much as possible below the longitudinal groove 6b.

As shown in FIG. 3, the water draining protrusion 7 has a front surface 7a of the water draining protrusion 7 as a concavely inclined surface inclined forward and downward, and the lower surface 7b of the water draining protrusion 7 has an inclination angle β with respect to the horizontal surface 7a. The vertical cross-sectional shape, which is a gently inclined surface inclined forward and downward at an inclination angle smaller than the inclination angle α, is a substantially triangular shape of forward and downward where the tip 7c protrudes forward. Therefore, the water flowing down in the vertical groove 6b from the tread portion 2 of the staircase flooring 1 smoothly flows to the front diagonally lower side along the concave front surface 7a without the water being attenuated, Since a forward moment is applied, it falls from the tip 7c (lower front end) of the draining projection 7 and completely drains without going around to the lower surface 7b which is a gently inclined surface. It is possible to prevent streaks from adhering to the front drooping portion 3 of the staircase flooring 1.
Although the vertical cross-sectional shape of the draining protrusion 7 is not limited to the above-described triangular shape, the triangular shape is most preferable as in this embodiment in consideration of draining performance and the like.
Further, as shown in FIG. 2, the step-up surface S3 of the staircase is provided so as to be inclined rearward with respect to the vertical from the corner portion 4 (the corner angle between the step surface portion S2 and the kick-up surface S3 is an acute angle). In such a case, the lower surface 7b of the draining protrusion 7 may be formed at a right angle from the groove 6 (a state in which the cross section of the draining protrusion 7 has a substantially right triangle shape).

The inclination angle α of the front surface 7a with respect to the horizontal surface of the draining projection 7 is preferably about 10 to 60 °. When the inclination angle α is within this range, the moving direction of the water flowing down in the groove 6b is oblique from the vertical direction. Since it smoothly moves downward and forward, it is possible to drain water appropriately without going around the lower surface 7b of the draining projection 7.
Note that the inclination angle α is particularly preferably 45 ° in order to drain the water without stagnation without excessively reducing the downward momentum and to give an appropriate forward moment. Further, it is extremely preferable to make the front surface 7a slightly concave because it can be smoothly guided forward without attenuating the water force. Furthermore, the inclination angle β of the lower surface 7b with respect to the horizontal plane is set to a range of about 0 to 45 ° smaller than the inclination angle α, and the lower surface 7b of the draining projection 7 can be set to the horizontal plane by setting the inclination angle β to 0 °. Good.

  The larger the protruding width of the draining protrusion 7 is, the higher the draining performance is. Further, the water temporarily accumulated in the tip 7c due to the very small amount of water flowing through the groove 6 is the surface tension or wind. The protruding width of the draining protrusion 7 is equal to or larger than the thickness of the built-up portion 5 so that the tip 7c does not move laterally and is transmitted to the built-up portion 5 due to the influence of About 10 mm. If it is in this range, the water flowing down in the groove 6b can be completely drained, and the water stagnated at the tip 7c is not transmitted to the built-up portion 5 and disturbs the pedestrian. Nor. Furthermore, the staircase flooring 1 of the present invention prevents the water temporarily accumulated at the tip 7c of the draining projection 7 from reaching the built-up portion 5 more reliably. Is provided so as to be positioned about 1 to 5 mm below the lower end of the built-up portion 5. In this way, the water draining protrusion 7 is formed with a large protruding width, and the tip 7c is positioned below the lower end of the built-up portion 5, so that water flowing down to the tip 7c of the draining protrusion 7 temporarily Even if the water stays, the water does not reach the built-up portion 5.

  In addition, in order to further improve the draining performance of the draining projection 7, as shown in FIG. 5, a mode in which the tip 7 c of the draining projection 7 is pointed downward as viewed from the front is also preferable. If the tip 7c of the draining projection 7 is sharpened in this way, water is less likely to stay on the tip 7c, and the water droplets are liable to fall, and the water drops do not move laterally on the tip 7c. Water is not transmitted to the built-up portions 5 and 5.

  The draining protrusion 7 can be provided within a range of about 5 to 49 mm downward from the upper end of the vertical groove 6b. However, the draining protrusion 7 is provided on the upper side of the vertical groove 6b. Then, the water reaching the draining projection 7 has no momentum, and the flow of water is not stable, so that it may be impossible to drain completely. Therefore, it is preferable that the draining protrusion 7 is provided at the lower end portion of the vertical groove 6b, that is, at a lower portion than the boundary line when the vertical groove 6b is divided into two in the height direction.

  When it is desired to improve the appearance of the flooring material 1 for staircases by making the draining protrusion 7 as inconspicuous as possible, the lower surface 7b of the draining protrusion 7 is set at the same position as the lower end of the built-up portion 5 as shown in FIG. At the same time, the protruding width of the draining protrusion 7 may be formed in the same dimension as the thickness of the built-up portion 5 (the tip 7c of the draining projection 7 and the surface of the built-up portion 5 are flush).

  The staircase flooring 1 of the present invention composed of the members as described above is approximately 90 after extruding a synthetic resin such as a vinyl chloride resin into a substantially L shape by extrusion molding or the like, or extruding it into a flat plate shape. ° Can be easily molded by bending. At this time, the roll may be thermocompression bonded to transfer a desired shape, and the build-up portion 5 and the draining protrusion 7 may be formed. Further, the build-up portion 5 and the draining protrusion 7 are not necessarily provided integrally with the staircase flooring 1 and may be provided by being molded separately and then fixed to the tread surface portion 2 or the front drooping portion 3 by adhesion or the like. .

  Next, in order to cover the staircase S with the staircase flooring 1 having the above-described configuration, first, an adhesive (not shown) is applied to the tread surface S2 and the raised surface S3 of the staircase S, and then the staircase flooring material. The construction is completed by arranging and sticking the 1 tread surface portion 2 and the front hanging portion 3 to the tread surface S2 and the kick surface S3 of the stairs S, respectively. At this time, if a gap is generated between the corner portion 4 of the staircase flooring 1 and the corner portion S4 of the staircase S, the gap may be filled with a sealing agent (not shown).

  As described above, the staircase 1 according to the present invention and the staircase S covered with the staircase floor 1 are subjected to water when the tread surface portion 2 gets wet with water due to rain or cleaning. Flows to the front drooping part 3 according to the water gradient of the tread part 2. At this time, if the drainage protrusion 7 is only provided on the front drooping portion 3, substantially uniform water flows down on the entire lateral surface of the front drooping portion 3, and thus flows down particularly when the amount of water flowing down is small or the head wind is blowing. Water wraps around the lower surface 7b of the draining protrusion 7 and flows in a streak manner on the front drooping portion 3 and the raised surface S3 of the staircase S. As a result, streaks flowing blackish water adhere and impair the beauty, but the staircase S covered with the floor material for staircases of the present invention is provided with a plurality of overlaying parts 5 in the corner part 4, Since the water is once blocked by the built-up portion 5 on the tread surface portion 2 side and collected in the horizontal groove 6a formed between the built-up portions 5 and 5, the water flows down the vertical groove 6b. The amount of water to be generated is much greater than when there is no built-up portion 5, and the water that flows down is stably continuous and less interrupted. As a result, the water draining projection 7 provided in the vertical groove 6b makes it easy to drain the water, so that the water does not travel on the lower surface 7b of the draining projection 7, and the stepping on the floor material 1 for the staircase located below is performed. Since it falls to the surface part 2, there exists a remarkable effect that a streak-like dirt does not adhere to the front drooping part 3 of the floor material 1 for stairs and the kicking surface S3 of the stairs S.
