Description

  The present invention relates to a floor material used for a railway vehicle.

  The railcars are made of polyvinyl chloride or rubber long floor coverings that have the appearance of a passenger car and anti-slip properties when walking. In addition, floor coverings with a convex-shaped deep draw on the surface are used for water circulation (toilet and washroom) in railway vehicles to ensure anti-slip properties when wet.

  In recent years, with the progress of plastic bottle making such as soft drinks, passengers often bring drinking water into the rail car carriages, and the carried drinking water etc. is increasingly diffused to the floor. In particular, when drinking in a passenger seat such as a side seat (cross seat), the liquid in the contents may be dumped on the floor due to the fall of the container etc. Spreads to the front and back of the passenger's seat, and it becomes a problem that the front and back passengers contaminate loads and bags placed on the floor.

  As a method of preventing the spread of the spilled liquid on the floor surface, there is a method of installing one having a height with respect to the floor surface like a weir. In order to prevent the liquid leaked to the floor surface from diffusing into the adjacent area, Patent Document 1 discloses a water-resistant weir of a predetermined height along with the base material standing on a strip-like base material and the upper part of the base material. And a water blocking plate to form a diffusion preventing structure. Moreover, in order to prevent the water from flowing out to the dedicated use portion for the next house on the balcony of the collective housing in Patent Document 2, the cross-section has a trapezoidal shape in the width direction of the balcony floor near the border with the next house. The drainage partition structure which installed the member and laid the floor sheet from the top is disclosed.

  The method of providing a bowl like this is effective for performing a specific relatively wide range of water stop. However, there is an unspecified number of places where the liquid spills on the floor of the railway vehicle passenger car, and if the range to be divided by the fence is set narrow to reduce the diffusion range of the liquid, the number of members increases and the construction work becomes complicated and the weight becomes too Unfavorably because it increases. Also, if a large convex portion to be wrinkled is provided in advance on the surface of the floor material, for example, in the case of a long floor covering, it becomes difficult to make a roll and store after manufacture, and transportation to the construction site Will be affected.

  Hereinafter, embodiments of the present invention will be described.

The floor material for rail vehicles of the present invention will be described with reference to FIGS. 1 and 2.
The floor material 1 for railway vehicles of the present invention is provided with a plurality of band-like dents 2 provided in a concave shape whose periphery is closed at a part of the surface as shown in FIG. Since the band-like recess 2 is provided on the surface of the floor material 1 for a railway vehicle in a concave shape, the end edge of the band-like recess 2 is formed in a wall shape from the surface of the floor toward the back surface. A wall 22 which is an edge surrounds the band-like recess 2. That is, the band-like recess 2 is formed as a closed space by being surrounded by the wall 22. The plurality of band-like dents 2 are continuously arranged to form a band-like dent group 3.

  FIG. 2 shows a cross-sectional view taken along the line AA ′ of FIG. The band-like recess 2 is composed of a bottom 21 and a wall 22. And the band-like dent part 2 which adjoins the top part 23 adjacently is provided continuously. By continuously forming the band-like indents 2 in this manner, the distance of movement of the liquid from A to A ′ is increased, which has the effect of stalling the flow of the liquid. Furthermore, when the liquid passes through the band-like recess 2, a lateral flow is generated that flows in the band-like recess 2, so the amount of liquid flowing from A to A ′ decreases.

  The depth d of the band-like recess 2 is about 1/20 to 1/2 of the thickness t of the floor material 1 for a railway vehicle. 0.1 mm-1.0 mm are preferable and, as for the depth d of the strip | belt-shaped dent part 2, 0.2 mm-0.8 mm are more preferable. If the depth d of the band-like depressions 2 is smaller than 0.1 mm, the effect of reducing the flow and diffusion of the liquid is difficult to obtain, and if it exceeds 1.0 mm, dirt tends to be accumulated and the cleaning performance tends to decrease. .

  The plurality of band-like dents 2 are arranged in parallel so that the longitudinal sides thereof face each other as shown in FIG. Moreover, when the floor material 1 for rail vehicles of this invention consists of a long sheet-like thing, the strip | belt-shaped dent part 2 is arrange | positioned so that it may be across the width direction of the floor material 1 for rail vehicles, It is preferable that the belt-like recess 2 be disposed so as to extend in the longitudinal direction of the floor material 1 for a railway vehicle. It is preferable that the band-like dents 2 be arranged such that the length of the band-like dents 2 is perpendicular to the direction in which it is desired to prevent the diffusion of the liquid.

  The plurality of band-like dents 2 arranged in parallel are arranged at a constant interval p as shown in FIG. 1 mm-about 50 mm are preferable, and, as for the width w of the narrow width direction of the strip | belt-shaped dent part 2, 3 mm-30 mm are more preferable. Further, it is preferable that the distance p between the band-like dents 2 be equal to the width w of the band-like dents 2 in the narrow direction or smaller than the width w of the band-like dents 2 in the narrow direction. About 0.5 mm-about 50 mm are preferable, and, as for the space | interval p of the strip | belt-shaped dent part 2, 1 mm-30 mm are more preferable.

  When the liquid flows from A to A ′ in FIG. 1, the liquid flows into the band-like recess 2 and is further diffused in the lateral direction to reduce the force of the liquid. Then, the velocity of the liquid flowing out beyond the band-like dent 2 is also reduced and flows through the top 23. At this time, even if the liquid is accelerated even by the inclination of the floor surface or the movement of the vehicle, if the top 23 which is a section accelerated without an obstacle is short, the liquid moving the top 23 does not have a large speed. Since the liquid flows into the next band-like recess 2, the velocity of the liquid can be effectively reduced, and the diffusion of the liquid can be easily prevented.

  A plurality of band-like dents 2 are continuously arranged to form a band-like dent group 3. The number of band-like dents 2 forming one band-like dent group 3 is preferably two to ten, and more preferably four to eight. The band-like dent group 3 has the effect of reducing the diffusion of the liquid as the number of band-like dents 2 constituting increases, but there is a possibility that the designability and the cleaning property may be reduced. Is preferred.

  A band-like dent group 3 in which a plurality of band-like dents 2 are continuously arranged is provided on the surface of the floor material 1 for a railway vehicle, and the arrangement of the band-like dent group 3 is determined according to the place to be constructed.

  The example of arrangement | positioning of the band-like dent group 3 in case the floor material 1 for railway vehicles is constructed by the passenger-car floor in which a seat is installed in FIG. 3 was shown. For example, if the distance Ls between the seats Se is 1000 mm pitch, it is preferable to provide the band-like dent group 3 at 1000 mm pitch so that the band-like dent group 3 is disposed under the seat Se. Thus, by providing the band-like dent group 3 under the seat Se, when liquid such as a beverage is spilled, it is possible to stop at the band-like dent group 3 without flowing to the front and back seats.

  Although there is no restriction | limiting in particular as the floor material 1 for rail vehicles of this invention, Since it is easy to provide an unevenness | corrugation freely on the surface, the floor material made from a synthetic resin is used suitably. Examples of synthetic resins include polyvinyl chloride, ethylene-vinyl chloride copolymer, propylene-vinyl chloride copolymer, vinyl chloride-acrylic resin copolymer, vinyl chloride-urethane copolymer, vinyl chloride-vinylidene chloride co-polymer Examples thereof include polymers, vinyl chloride resins such as vinyl chloride-vinyl acetate copolymers, and olefin resins such as polyethylene and polypropylene. These may be used alone or in combination of two or more. Among these synthetic resins, polyvinyl chloride is preferred in view of processability, workability and cost.

  Moreover, the floor material 1 for rail vehicles of this invention is a long sheet-like thing, and it is preferable to match and provide the band-like dent group 3 with a construction vehicle previously. It is difficult to install a long sheet-like floor material at an arbitrary position at the time of construction, and it is more effective by providing a band-like dent group 3 in advance according to the place where the diffusion of liquid is desired to be reduced. It is possible to reduce the diffusion of the liquid. More specifically, the shape of the site where the installation position in the longitudinal direction and the width direction (lateral direction) in a long floor material and the space (pitch) of a plurality of band-like dent groups 3 are applied, the direction of liquid flow, and diffusion are prevented It is preferable to provide the band-like dent group 3 in advance in consideration of the desired direction and the position where it is assumed that the liquid will spill. The band-like recess 2 can be provided by embossing, pressing, or the like. In addition to this, a grated pattern may be provided on the entire surface of the floor material 1 for a railway vehicle in order to improve design and slip resistance. A diaphragm provided on the entire surface is preferably a shallow diaphragm in consideration of the cleaning property.

  Here, the floor material 1 for railway vehicles is suitable not when the large amount of liquid flows or when the liquid flows for a long time, but when the relatively small amount of liquid flows. The band-like dent group 3 consisting of a plurality of band-like dents 2 reduces the diffusion speed of the liquid and has an effect of temporarily retaining the liquid, and such an effect works more effectively when the liquid is relatively small.

  Corresponds to the amount of liquid assumed by changing the depth and width of the band-like dents 2, the number and interval of the band-like dents 2 constituting the band-like dent group 3, the arrangement, and the spacing and arrangement of the plurality of band-like dent groups 3 can do. In general, the floor material 1 for rail vehicles is more suitable for cases of 500 ml or less, furthermore 100 ml or less, in particular 50 ml or less.

Hereinafter, examples of the present invention will be described.
A band-like dent group consisting of a plurality of rectangular band-like dents as shown in Table 1 on the surface of a floor sheet having a thickness of 2.0 mm and a polyvinyl chloride-based floor sheet having a shallow draw on the entire surface. Were formed by an electric heat press. As a comparative example, a floor sheet provided with the same shallow drawing as that of the embodiment on the entire surface without using a band-like dent portion was used.
These floor sheets were fixed to a construction table with an adhesive to prepare a test body as shown in FIG. Here, the width W1 of the test body is 500 mm, and the length L1 between B-C (development section) and the length L2 between C-D (measurement section) are both 500 mm. The band-like dent group 3 was placed at the center of C-D (measurement section). A liquid reservoir consisting of a plate-like piece of a plastic shock absorbing material was installed at the start point S of this test body to make a testing machine.

  The above-mentioned tester was set at an inclination angle of 2 °, and 5 ml of water was stored in a liquid reservoir to be stationary and then drained at once. After passing between B and C (developing section), the time from when the liquid first passes point C to between C and D (measuring section) until the liquid reaches to D point is 1/100 sec by stopwatch It measured. This measurement was measured 10 times for each of the floor sheets of Examples and Comparative Examples, and the average value was rounded to one decimal place to calculate the liquid diffusion time. Based on this, the liquid diffusion reduction effect was evaluated according to the following criteria.

<Liquid diffusion reduction effect>
:: very effective (liquid diffusion time 5.0 seconds or more)
○: Effective (liquid diffusion time 4.0 seconds or more and less than 5.0 seconds)
:: Some effect (liquid diffusion time 3.0 seconds or more and less than 4.0 seconds)
X: no effect (liquid diffusion time less than 3.0 seconds)

  From the evaluation results of Table 2, in the floor sheets of Examples 1 to 5 in which the band-like dent group consisting of a plurality of band-like dents is provided on the floor surface, the liquid diffusion time is compared to the comparative example in which the band-like dents are not provided. It can be seen that the liquid diffusion reducing effect is obtained. From the comparison between Example 1 and Example 2, the larger the width of the band-like dent portion, the larger the liquid diffusion reduction effect. Further, it can be understood from the comparison between Example 3 and Example 4 that the effect becomes larger as the interval at which the band-like dents are provided is narrower. In addition, Example 5 in which the width and interval of the band-like dents are both narrow and the number of band-like dents is large is the most excellent in the liquid diffusion reducing effect, and the one with the narrow number of band-like dents and the large number is more effective. .

  The floor material for a railway vehicle according to the present invention can suppress the spread of the spilled liquid on the floor surface without using a special member or providing a convex portion serving as a ridge on the surface of the floor material, and further, the storage As it is easy to transport and has excellent construction, it can be suitably used as a floor for a railway vehicle passenger compartment.
