Description

  The present invention relates to a non-slip means for a floor surface of a vehicle transport ship that carries and transports automobiles or other vehicles, and more particularly to a non-slip sheet for a floor surface of a vehicle transport ship.

  In the case of an automobile transport ship or an automobile dedicated ship that carries automobiles, the cars to be loaded are driven one by one, are self-propelled, passed deeply into the ship of the transport ship through the slopes in the hold, and are parked in the hold. The vehicle is stopped at a predetermined position in a state of being aligned with a place like a car park, and is fixed to the floor of the cabin by fixing means for lashing. A large number of cars are lined up at the port car park at the port before the cars are loaded. If it rains during this time, the rainwater adhering to the car will fall, and the passage (traveling path) to the car loading cargo hold of the car transport ship and the floor in the hold will become slippery and should be loaded by self-running An automobile is likely to slip, and the automobile or other automobiles may be damaged due to a contact accident or the like.

  In addition, the passage (traveling path) and the floor of the hold in an automobile transport ship are substantially made of a steel plate such as iron, and usually the surface of the steel plate is coated with paint or paint for preventing rust. Therefore, the floor surface of the vehicle transport ship is slippery, and the floor surface is provided with anti-slip means.

  As the anti-slip means, for example, a plastic sheet provided with an anti-slip layer having ceramic particles attached on the surface side is used. When laying the plastic sheet, a strong adhesive is applied to the back side of the plastic sheet so as to prohibit the displacement of the plastic sheet relative to the floor of the transport ship, and the back side of the plastic sheet is applied to the floor of the transport ship. It is adhered to.

However, since the anti-slip layer is worn by use for several years (for example, about 2 to 3 years), it is necessary to replace the anti-slip means. In addition, used ships are often sold, and even in that case, it is necessary to peel off the anti-slip means in order to repaint the floor surface in order to clean the floor surface once. However, in these cases, since the anti-slip means is firmly adhered to the floor of the transport ship with a strong adhesive, it takes a lot of time and labor to remove the anti-slip means (for example, and even it takes nearly 30 minutes to peel off a piece of what a few minutes 1m ² about a small, also the cost is the time and effort it takes to peel off all the plastic sheet that tens of thousands of sheets per one ship is enormous Hard to ignore).

  In addition, a paint (anti-slip paint) containing hard particles mixed in a dispersed state is applied to the road surface to form a non-slip area on the road, or a binder made of a resin-based binder is applied to the surface of the pavement. It is known to perform paving having a non-slip function by spraying hard aggregate and fixing it to the road surface (Non-patent Document 1 and Non-Patent Document 2). This type of anti-slip paint is composed of, for example, an adhesive mainly composed of an epoxy resin or the like, and is strongly adhered to the road surface after being cured. It is necessary to dig up from the road. In addition, it has also been proposed to apply an epoxy resin coating in which hard particles are mixed in a dispersed state to a staircase made of steel or the like to prevent the stairway from slipping (Non-Patent Document 1). However, it is the same that it is not easy to remove an adhesive (paint) made of epoxy resin that is strongly bonded by curing.

  On the other hand, when the sheet body is made of hard plastic or the like, a high friction material made of silicon resin or synthetic rubber having a large friction coefficient is pasted on the back surface of the sheet, and grooves are cut into the high friction material, such as alumina. It has been proposed to increase the friction coefficient of the back surface of the sheet by mixing particles (Patent Document 1). However, in this case, depending on the force that the non-slip sheet receives from the vehicle, it is difficult to avoid the possibility that the non-slip sheet itself is displaced from the floor surface. In fact, the applicant of Patent Document 1 has proposed a completely different fixing means for fixing a seat with fastening means comprising anchor bolts and nuts in another application of the same date (Patent Document 2).

  Although it is different from the technology related to the floor of the ship, it has been proposed to use a sheet-like magnet as means for detachably covering a certain area under the floor of the building (Patent Document 3 and Patent Document). 4).

  However, in these proposals, the sheet-like magnet is used under the floor where there is no risk of receiving external force along the surface such as deviation stress, and under the condition of receiving the deviation stress directly. It does not suggest the possibility of using a sheet magnet.

Tanimura Corporation “Non-slip non-slip paint” [as of July 2010] Internet (URL: http://www.tanimura.biz/catalog/nonslip_coat.html) Japanese road "Pave with non-slip function" [as of July 2010] Internet (URL: http://www.nipponroad.co.jp/lineup/function/050.htm)

  Under the circumstances as described above, the present inventor has paid attention to the fact that the floor of the vehicle transport ship is made of a steel that is a ferromagnetic material. Whether or not the sheet magnet can be held in a state of being fixed to the steel floor surface (magnetically adsorbed or adhered) without being displaced along the floor surface even if it receives a force in the direction along As a result of the test, it was surprisingly found that the deviation can be held without actually occurring, as compared with the ease of peeling of the sheet-like magnet. That is, surprisingly compared with the ease of peeling of the sheet-like magnet, it is surprisingly received from the tire when a braking force is applied to the tire of the vehicle so that the braking can be surely performed when braking the vehicle such as an automobile. It was confirmed that the sheet-like magnet can be held in a fixed state (magnetically attracted) to the steel floor without any deviation even under the reaction.

  The present invention has been made on the basis of such new knowledge. The object of the present invention is to ensure that the floor surface of the vehicle transport ship can be prevented from slipping and can be easily peeled off from the floor surface. An object of the present invention is to provide an anti-slip sheet for a floor of a vehicle transport ship.

  The floor anti-slip sheet of the vehicle transport ship of the present invention has a sheet-like magnet and an anti-slip layer formed on one surface of the sheet-like magnet in order to achieve the above object.

  In the anti-slip sheet on the floor surface of the vehicle transport ship of the present invention, since the anti-slip layer is formed on one surface of the sheet-like magnet, the sheet-like magnet is installed so that the anti-slip layer is located on the surface side. If it arrange | positions, it can suppress that the tire of vehicles, such as a motor vehicle which runs on the floor of a vehicle transport ship, slips.

  Further, since the floor of the vehicle transport ship is substantially made of steel and is substantially made of a ferromagnetic material, the anti-slip layer of the sheet-like magnet is formed in the floor slip prevention sheet of the vehicle transport ship of the present invention. When the sheet-like magnet is arranged on the floor surface so that the surface opposite to the surface (the above-mentioned “one surface”) actually contacts the floor surface of the vehicle transport ship, Since the surface is strongly attracted by the static magnetic force, the floor surface non-slip sheet disposed on the floor surface is strongly fixed to the floor surface. This fixing is performed even when a slip stress in a direction along the floor surface is applied to the floor anti-slip sheet, and the floor surface anti-slip sheet is displaced along the floor surface with respect to the steel floor. It is strong enough to actually ban it. Therefore, when a braking force is applied to the tire of the vehicle, a large slip stress is applied in the direction along the floor surface as a reaction to the floor surface anti-slip sheet, but in the floor surface anti-slip sheet of the vehicle transport ship of the present invention, The sheet magnet is strongly magnetically attached (adsorbed with a strong magnetic attraction) to the ferromagnetic floor of the vehicle transport ship (hereinafter also referred to as “ferromagnetic floor”). Since it is firmly fixed to the floor surface, the floor surface anti-slip sheet is firmly held on the floor surface against the displacement stress. As a result, a large braking force is applied to the vehicle tire, and the tire Can be effectively prevented. Therefore, the anti-slip sheet for the floor of a vehicle transport ship according to the present invention can reliably exhibit an anti-slip effect by utilizing the characteristics of the floor of the vehicle transport ship in a vehicle transport ship having a floor made of steel.

  That is, for example, in the case of rainy weather, it is difficult to avoid vehicles such as cars parked at the vehicle stop accumulation place near the port getting wet in the rain, and the vehicles enter the stop area in the ship like a multi-level parking lot by self-propelled When the rainwater falls into the ship and the floor surface easily slips, the floor surface of the vehicle transport ship according to the present invention is only laid on the floor surface, and the floor surface is less likely to slip. The anti-slip effect can be exerted reliably.

  Furthermore, in the floor anti-slip sheet of the vehicle transport ship of the present invention, the anti-slip sheet is fixed to the floor surface by the magnetic attraction between the sheet-like magnet and the steel floor surface. Therefore, the anti-slip sheet can be easily peeled off from the steel floor simply by pulling the flexible anti-slip sheet so as to bend and peel off the desired edge. That is, unlike the conventional case where the non-slip sheet is adhered to the floor surface with a strong adhesive, the peeling can be easily performed in a very short time. In addition, unlike the conventional non-slip sheet using a strong adhesive, the floor anti-slip sheet of the vehicle transport ship of the present invention has no possibility of remaining after peeling. The desired processing (cleaning, repainting, etc.) can be immediately performed, and the labor required for the peeling-related work can be minimized.

  In the floor anti-slip sheet of the vehicle transport ship of the present invention, typically, the sheet-like magnet is composed of a large number of magnetic particles and a resin layer or a rubber layer that fixes the magnetic particles in a dispersed state.

  In that case, a relatively thin and relatively large sheet-shaped magnet is obtained, and once laid on the floor surface, a strong magnetic attractive force can work between the steel floor and the anti-slip sheet. Can be securely fixed to the floor without fear of displacement. Further, for example, in the case of a rubber layer or a relatively soft resin (plastic) similar to rubber, the floor surface non-slip sheet itself is provided with a buffer in the thickness direction between the anti-slip layer and the floor surface. Since it can be a layer, it can be avoided that the road surface on which the tires of the vehicle are placed becomes too hard.

  However, if desired, the layer for fixing and holding the magnetic particles of the sheet-like magnet may be a layer of relatively hard resin (plastic) or the like.

  In any case, in the sheet-like magnet, the magnetic particles are dispersed and held in a binder made of a resin or the like so that the sheet form can be taken as a whole. Since a large number of small magnets exert a magnetostatic attractive force on the adjacent ferromagnetic floor, the sheet-like magnet is attracted to the steel floor with a large force as a whole. That is, for example, when a thin plate made of a soft magnetic material (magnetically soft ferromagnetic material) is magnetized along the extending surface of the thin plate or a permanent magnet made of a magnetically hard continuous and uniform material. Unlike the case, the magnetic poles of small magnets in the form of particles distributed in a non-magnetic binder in the non-magnetic binder at each part of the sheet can be exposed at or near the surface, so that the magnetic field lines passing through the magnetic poles A large percentage of lines of magnetic force pass through the ferromagnetic floor not only to the opposite magnetic poles of the adjacent small magnets but also to the adjacent ferromagnetic floor, so there is a large magnetostatic effect between the sheet magnet and the floor. It is understood that a strong attractive force can work (that is, in the vicinity of the side surface of the middle portion of the long magnet away from the magnetic pole portions at both ends, the situation is different from the case where the leakage of the magnetic field lines is small).

  The sheet-like magnet is typically magnetized in a direction along the extending surface of the sheet, but may be magnetized in a direction substantially perpendicular to the sheet surface if desired. The floor anti-slip sheet of the vehicle transport ship of the present invention is typically rectangular, and when the direction of magnetization is a direction along the extending surface of the sheet, it is in a direction parallel to the long side of the rectangle. Alternatively, the direction may be parallel to the short side or may be oblique to these.

In order to keep the cost to a minimum, the magnetic particles are made of ferrite such as Fe ₃ O ₄ , for example, but are actually in a ferromagnetic state (in a broad sense including ferrimagnetism etc.) at room temperature or in a temperature range of about several tens of degrees Celsius. Any magnet may be used as long as it is a magnetically hard magnetic material that is maintained in the meaning) and has a certain degree of magnetization in the normal operating temperature range. In addition, in the case where a larger magnetic force is desired even at a higher cost, for example, a rare earth alloy or an Nd—Fe—B magnet may be used.

  In the anti-slip floor surface of the vehicle transport ship of the present invention, the anti-slip layer may be basically any material as long as it is suitable for anti-slip of a traveling vehicle. In ship floor anti-slip sheets, the anti-slip layer typically has a roughened layer with an exposed surface roughened.

  Roughening of the exposed surface is achieved by applying shape or morphological unevenness to the surface of a substantially uniform material (the convex material and the supporting material that supports the convex material are made of the same material). Alternatively, the convex portion forming material and the support material that supports the convex portion forming material may be realized by a composite material made of different materials. In the latter case, the convex portion is easily formed of a hard material, and roughening is easily performed to increase friction.

  In the anti-slip sheet for a floor of a vehicle transport ship according to the present invention, typically, the roughening layer comprises a large number of rough surface forming particles and a particle fixing resin layer that holds or fixes the rough surface forming particles in a dispersed state. Including.

  In that case, the particle-fixing resin layer typically exposes a part of the rough surface-forming particles (for example, at least a fraction, typically about 1/2 or more). The rough surface-forming particles are fixed in a state where the lower portion of the rough surface-forming particles is embedded. As a result, it is easy to use the hard rough surface-forming particles while having flexibility as the sheet, and the sheet can be easily and reliably roughened in the state having flexibility. However, as long as the rough surface by the rough surface-forming particles can have sufficient roughness and the particle-fixing resin layer has sufficient flexibility in the form of a sheet, the particle-fixing resin layer is composed of most of the rough surface-forming particles. It may cover the part.

  The rough surface-forming particles typically consist of ceramic particles. Because of its relatively low cost and high hardness, it is suitable for anti-slip, so typically, ceramic particles are used for the anti-slip layer, but as long as they have the same degree of hardness so as to provide the same degree of anti-slip effect. It may be a resin or other material. Alumina (aluminum oxide) is typically used as the ceramic material, but other oxides, such as nitrides and borides, can be tolerated costly if desired. Ceramic materials other than oxides may be used. In addition, when the particles are relatively large as so-called aggregates, the particles typically have a plurality of types of metal oxides in various forms such as so-called “stones” that form aggregates. It can be a mixture. In such a case, the composition may differ or vary depending on the particles.

  The size of the particles is the same as that conventionally used for anti-slip of a traveling vehicle, and is typically about 0.1 mm, for example. However, as long as it can be applied to anti-slip of a traveling vehicle, for example, it may be about several mm as used for anti-slip coating or anti-slip pavement on a road surface, and it may be an intermediate size. Even if it is a desired size within a range of about 0.1 mm to several mm, it may be slightly larger than about several mm and smaller than about 0.1 mm if desired.

  In the floor surface anti-slip sheet of the vehicle transport ship of the present invention, typically, the rough surface forming particles of the rough surface layer are covered with a coating layer.

  In that case, the possibility that the rough surface-forming particles are separated from the particle-fixing resin layer due to exposure from the particle-fixing resin layer can be minimized. Here, the coating layer may be the same material as the particle-fixing resin layer or a different material. In the case of the same material, in reality, the flowability of the resin material is relatively high, the rough surface forming particles are dispersed in the resin material, and the conventional anti-slip pavement and slick coating are used. Similarly, a resin material holding the rough surface forming particles in a dispersed state may be applied on one surface of a sheet serving as a substrate and solidified or cured.

  However, such a coating layer may be omitted if desired, for example, when the fixation is relatively strong or there is a reason that the anti-slip force needs to be maximized.

In the anti-slip sheet on the floor of the vehicle transport ship of the present invention,
(1) Even if the anti-slip layer is fixed to the one surface of the sheet-like magnet by an adhesive, or (2) the particle-fixing resin layer constituting the anti-slip layer is directly on the one surface of the sheet-like magnet. It may be fixed.

  In the former case (ie, (1)), the sheet-like magnet and the anti-slip layer may be manufactured separately under suitable conditions, and the two may be integrated. Therefore, the manufacture is easily performed.

  In the latter case (ie, (2)), the structure is simplified and the cost is easily minimized.

  In the floor anti-slip sheet of the vehicle transport ship of the present invention, if desired, a slightly adhesive paste layer may be formed on the other surface of the sheet magnet. Here, the slightly adhesive paste layer is a layer that can be easily peeled off at the time of peeling, unlike the conventional adhesive layer. In that case, since the slightly adhesive paste layer holds the other surface of the sheet magnet and the floor surface in a close contact state, for example, water or oil falls on the floor and the floor surface becomes water or oil. Even when wet, the water or oil spreads between the other surface of the sheet-like magnet and the floor surface, and the risk of reducing the friction between the other surface of the sheet-like magnet and the floor surface is minimized. It can be limited to the limit.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a method of peeling a floor surface anti-slip sheet of a vehicle transport ship according to a preferred embodiment of the present invention, where (a) is an explanatory plan view showing how to peel and (b) shows the state of peeling. Cross-sectional explanatory drawing.

  Several preferred embodiments of the present invention will be described based on preferred examples shown in the accompanying drawings.

  FIG. 1 shows a floor anti-slip sheet 1 of a vehicle transport ship according to a preferred embodiment of the present invention. In FIG. 1, the thickness direction Z of the sheet 1 is exaggerated and enlarged so that the laminated structure of the floor surface anti-slip sheet 1 can be easily seen.

  The floor slip prevention sheet 1 of the vehicle transport ship has a sheet-like slip prevention part 2 and a sheet-like magnet part 3. In the sheet 1, the sheet-like anti-slip part 2 and the sheet-like magnet part 3 are fixed by an adhesive layer 5. The thickness of the floor surface anti-slip sheet 1 of the vehicle transport ship is typically about 1 to 5 mm. However, it may be thicker (for example, about 1 cm thick) as long as there is no risk of hindering the progress of the vehicle as it travels. As long as the force is ensured and the anti-slip function of the sheet-like anti-slip portion 2 is ensured, the thickness may be thinner.

  In this example, the sheet-like anti-slip portion 2 includes a plastic base layer or plastic base layer 10 and an anti-slip particle layer 20. In the case of this example, even if the sheet-like non-slip portion 2 is regarded as a roughened layer, the anti-slip particle layer 20 may be regarded as a roughened layer. In the following, for the sake of simplicity of explanation, it is assumed that the sheet-like non-slip portion 2 is a roughened layer, and more specifically, the anti-slip particle layer 20 of the sheet-like non-slip portion 2 is a roughened layer. To do.

  The plastic base material layer 10 is a layer for supporting the anti-slip particle layer 20, and is made of, for example, a film made of PVC (vinyl chloride resin). The thickness of the base material layer 10 is, for example, about 0.1 mm. However, for example, it may be as thick as about 1 mm or more, or as thin as about 0.01 mm or less. The material of the plastic base material layer 10 is flexible and has points such as resistance to load and load, and normal changes in temperature (for example, in the range of about several tens of degrees Celsius to +100 degrees Celsius), water and oil. Any other resin may be used as long as it can be adapted to the usage environment.

  The non-slip particle layer 20 includes, for example, a large number of ceramic particles 22 dispersed in a dispersed state on the surface 11 side of the plastic substrate layer 10 as shown in detail in the cross-sectional explanatory view of FIG. A particle fixing resin layer (which may be referred to as a ceramic particle fixing binder or a ceramic particle fixing adhesive layer) 24 that fixes the particles 22 to the surface 11 side of the plastic base layer 10. The anti-slip particle layer 20 may be one that has been conventionally used for anti-slip on roads and the like.

  The ceramic particles 22 are typically dispersed along the extending surface S of the sheet 1 to such an extent that the particles 22 do not actually overlap each other. However, if desired, the ceramic particles 22 may overlap each other as long as the ceramic particles 22 can be held without actually leaving the base layer 10 and the flexibility of the sheet 1 can be maintained. In the following, for the sake of simplification of description, it is assumed that the ceramic particles 22 are arranged in a dispersed state without actually overlapping unless otherwise specified. In the figure, for ease of illustration, the adjacent ceramic particles 22 are shown as being practically intimate, but typically there are often at least some gaps between adjacent particles.

  Here, the size (average particle size) of the ceramic particles 22 is typically a desired size between about 0.1 mm and several mm. However, it may be smaller as long as a sufficient anti-slip effect is obtained, and may be larger as long as there is no fear of damaging the tire or the like beyond the normal anti-slip action. In addition, although the size of the ceramic particles 22 is shown in the drawing as being similar to each other for ease of illustration, typically, the size of the ceramic particles 22 includes several numbers. There can be more than double (a fraction of) variation. However, the same degree may be sufficient.

  Typically, when the size of the ceramic particles 22 is relatively large, the thickness of the plastic substrate layer 10 is also relatively thick so that the particles 22 can be supported. However, the thickness of the plastic substrate layer 10 may be relatively thin as long as the layer 20 including the ceramic particles 22 can be supported.

  The material of the ceramic particles is typically made of alumina (aluminum oxide), but can be other metal oxides if desired, so long as they are hard and not easily broken (not too brittle), so-called bone. Like a material, what was called a stone or a plurality of kinds of metal oxides may be mixed. The material of the ceramic particles may also be other ceramics such as nitrides and borides, unless excessive costs are involved. Furthermore, the particles may be made of plastic or other material instead of ceramic as long as sufficient hardness is obtained as the particles and heat resistance, water resistance, oil resistance, etc. according to the use environment can be secured. Good.

  The particle fixing resin layer 24 fixes the ceramic particles 22 to the base material layer 10 and may be made of an adhesive or the same material as the base material layer 10 or the same material. In the latter case, the particle fixing resin layer 24 may be a part of the base material layer 10, typically a part of the base material layer 10 itself. In that case, there is no interface between the base material layer 10 and the particle fixed resin layer 24, and the two are continuously connected.

  In any case, the portion that becomes the particle fixed resin layer 24 is such that a part of the ceramic particles 22 enters the particle fixed resin layer 24, in other words, the resin material that constitutes the particle fixed resin layer 24. Is smaller than the average particle size of the ceramic particles 22 (typically less than about 1/2 of the average particle size of the ceramic particles 22, so as to cover a partial region 22 a below the ceramic particles 22. The remaining portion 22 b of the ceramic particle 22 is exposed above the particle fixing resin layer 24.

  Here, the coating layer 26 is applied so as to cover the upper exposed portion 22b of the ceramic particles 22 as in the anti-slip sheet 1A of the floor surface of the vehicle transport ship shown in the cross-sectional explanatory view of FIG. May be. In that case, the ceramic particles 22 can be minimized. The coating layer 26 may be made of an adhesive layer different from the resin constituting the particle fixing resin layer 24, or may be made of the same or similar resin as the resin constituting the particle fixing resin layer 24. Good. In the latter case, the ceramic particles 22 are dispersed in the fluid resin material forming the particle fixing resin layer 24 and the coating layer 26, and the fluid resin material in which the particles 22 are dispersed is, for example, a substrate. The anti-slip particle layer 20 (in FIG. 2B, the anti-slip particle layer 20A) may be formed by applying to the surface 11 of the layer 10.

  In the floor surface anti-slip sheet 1A of the vehicle transport ship having the sheet-like anti-slip part 2A having the anti-slip particle layer 20A provided with the coating layer 26, there is little possibility that the ceramic particles 22 are peeled off. 2 (b), the same elements as those of the seat 1 shown in FIG. 2 (a) are designated by the same reference numerals. The elements of the sheet 1 shown in (a) of FIG. 2 are substantially the same as the elements of the sheet 1 but are different from each other.

  In FIGS. 1 and 2 (a) to (d), as described above, the ceramic particles 22 of the anti-slip particle layer 20 are shown as if they are arranged without gaps when viewed along the extending direction of the plane S. In practice, however, there may be some clearance between adjacent particles 22. In addition, as long as the particles 22 are actually securely fixed, there is no overlap between the particles 22 and 22 and they may overlap somewhat.

  The sheet-like magnet section or the sheet magnet 3 includes a large number of magnetic particles 51 and a magnetic particle holding layer 52 in the form of a binder that fixes the magnetic particles 51 in a dispersed state. In FIGS. 1 and 2 (a) to (d), although the sheet-like magnet unit 3 includes a large number of magnetic particles 51, many points are drawn, but the sheet-like magnet unit 3 is configured. The large number of magnetic particles 51 are typically about several tens of μm or less in size (particle size), and are difficult to see in practice, and may be displayed depending on a visually observable area or size. Although it is difficult, it is exaggerated here. The magnetic particle holding layer 52 is made of a rubber layer or a relatively soft resin layer like rubber. However, as long as the sheet 1 can have flexibility as a whole, the resin layer 52 may be a relatively hard resin layer or the like.

  The sheet-shaped magnet portion 3 is typically magnetized in a direction along the extending surface (surface parallel to the XY plane) S of the sheet 1, but if desired, the sheet surface (surface parallel to the XY plane). ) It may be magnetized in a direction Z that is actually perpendicular to S.

  The floor anti-slip sheet 1 of this vehicle transport ship is typically rectangular, and in the direction X parallel to the long side of the rectangle when the direction of magnetization is a direction along the extending surface S of the sheet. Even in this case, the direction Y may be parallel to the short side or may be oblique to these.

  Here, in the sheet-like magnet unit 3, the magnetic particles 51 are dispersed and held in a binder 52 made of a resin or the like so that the form of the sheet can be taken as a whole. Since a large number of small magnets 51 exert a magnetostatic attractive force on the adjacent ferromagnetic steel floor F, the sheet magnet 3 is attracted to the steel floor F with a large force as a whole. . That is, in the sheet-like magnet 3, for example, when a thin plate made of a soft magnetic material (magnetically soft ferromagnetic material) is magnetized along the extending surface of the thin plate, or magnetically hard continuous and uniform. Unlike the case of a permanent magnet made of a material, the magnetic poles of small magnets 51 in the form of particles distributed in a non-magnetic binder 52 in each part of the sheet 1 at some distance from each other are exposed at or near the surface. Therefore, the magnetic field lines passing through the magnetic poles are directed not only to the opposite polarity magnetic poles of the adjacent small magnets 51 but also to the surface F1 of the adjacent ferromagnetic steel floor F, and a considerable percentage of the magnetic field lines pass through the ferromagnetic steel floor F. Therefore, it is understood that a large magnetostatic attractive force can act between the sheet-shaped magnet 3 and the floor F (that is, the side surface of the intermediate portion away from the magnetic pole portions at both ends of the long magnet). Magnetic field leakage in the vicinity It becomes a different situation than the one is small).

The magnetic particle 51 is typically made of a ferrite such as iron ferrite Fe ₃ O ₄ , but is actually kept in a ferromagnetic state (in a broad sense including ferrimagnetism) at a normal temperature or a temperature range of about several tens of degrees Celsius. Any magnet may be used as long as it is made of a magnetically hard magnetic material that has a certain degree of magnetization in the normal operating temperature range. If a larger magnetic force is desired even if the cost is high, for example, an anisotropic ferrite magnet, an Alnico (Al-Ni-Co) magnet, a rare earth alloy or the like (for example, samarium) Cobalt (Sm-Co) -based magnets) and Nd-Fe-B-based magnets may be used. The coercive force is preferably high, but may not be so high as long as it is not practically demagnetized under the conditions of the normal use range. When it is necessary to avoid oxidation or the like of the material of the magnetic particles 51, the magnetic particles may be coated and then dispersed in the binder 52.

  The sheet-like magnet part 3 typically has a thickness of about 0.5 mm to about 3 mm. However, as long as the sheet-shaped magnet portion 3 can have a sufficient magnetostatic strength and the sheet 1 as a whole can sufficiently withstand the load in the thickness direction and does not become excessively flexible, it can be thinner, Moreover, as long as there is no possibility that the seat 1 is too thick and hinders the running of the vehicle as a whole, it may be thicker. In addition, the sheet-like magnet portion 3 is formed so as to be thicker as the width is narrower (in other words, thinner as the width is wider), and as a whole, the strength of the magnet is maintained at a desired level or more.

The binder 52 is any resin-based material (including rubber-based material) as long as it can hold the magnetic particles 51 in a dispersed state in a chemically stable and mechanically strong manner and can have flexibility. If the magnetic particles are made of iron ferrite Fe ₃ O ₄ , for example, chlorinated polyethylene is used. However, the binder 52 is made of any plastic material (including a rubber-based material) as long as the magnetic particles 51 can be held in a dispersed state in a chemically stable and mechanically strong manner and have flexibility. There may be.

  Typically, as shown in FIGS. 2A and 2B, the sheet-shaped magnet portion 3 is directly fixed or attracted to the surface F1 of the floor F of the vehicle transport ship by a magnetic attraction force. Is done.

  However, if desired, a slightly adhesive paste layer 60 may be further formed on the bottom surface 53 of the sheet-shaped magnet portion 3 as shown in the cross-sectional explanatory view of FIG. In this case, the sheet-like magnet portion 3 is not only fixed or adsorbed to the surface F1 of the floor F of the vehicle transport ship directly by the magnetic attractive force, but also the slightly adhesive paste layer 60 on the bottom surface 53. Is attached to the surface F1 of the floor F to such an extent that it can be easily peeled off. Here, the slightly sticky glue layer 60 is a layer that can be easily peeled off at the time of peeling, unlike the adhesive layer of strong adhesion, and is made of, for example, an acrylic adhesive. However, other materials may be used. In the case where the slightly adhesive paste layer 60 is formed, a so-called release paper is typically placed on the surface of the slightly adhesive paste layer 60, and the release paper is used in use. Is peeled off.

  In this case, not only the resistance against the momentary displacement stress is somewhat higher, but the slightly adhesive paste layer 60 is formed on the bottom surface 53 of the sheet-like magnet 3 and the surface of the floor F made of ferromagnetic steel, that is, the floor surface F1. For example, even when water or oil falls on the floor F and the floor surface F1 gets wet with water or oil, the water or oil remains on the bottom surface 53 of the sheet-like magnet 3 and the floor surface. The possibility that the friction between the bottom surface 53 of the sheet-like magnet and the floor surface F may be reduced to a minimum by spreading between F1 and F1. In addition, it is preferable that this glue layer 60 is thin so that the space | interval of the bottom face 53 of the sheet-like magnet 3 and the floor surface F1 made from a ferromagnetic steel may become small, for example, 0.01mm-0. It is preferable that it is about 1 mm or less. However, depending on the case, it may be thicker than about 0.1 mm.

  Note that the slightly adhesive paste layer 60 may be formed on the entire surface of the bottom surface 53 or may be formed in a band shape on a part of the bottom surface 53. When it is formed on a part of the bottom surface 53, it is preferably formed on most of the region of the bottom surface 53. When it is formed in a strip shape, for example, it may be formed in two rows as a whole in the vicinity of each end in the width direction, in a single row in the center, in three or more rows at a desired location, Good.

  In addition, in the floor slip prevention sheet and its elements of the vehicle transport ship of FIG. 2 (c), the same elements as those of the seat 1 or 1A shown in FIGS. 2 (a) and (b) are the same. 2 are generally the same as the elements of the sheet 1 or 1A shown in FIGS. 2A and 2B but are different from those of the sheet 1 or 1A. Subscript B is added later.

  Further, instead of the plastic base layer 10 and the sheet-shaped magnet portion 3 being fixed to each other via the adhesive layer 5, as shown in FIG. The floor slip prevention sheet 1C of the vehicle transport ship to which the magnet portion 3C is directly fixed may be used. In that case, for example, a thin intermediate layer that is highly compatible with both the resin of the plastic base material layer 10C and the resin that forms the magnetic particle holding layer 52C of the sheet-shaped magnet portion 3C and actually works in the same manner as the adhesive layer. Although the resin for forming the plastic particle layer 10C and the resin for forming the magnetic particle holding layer 52C for the sheet-like magnet portion 3C may be formed of a similar resin or a highly compatible resin, Alternatively, one may be formed on the other surface.

  In the floor surface anti-slip sheet 1C of the vehicle transport ship, the coating layer 26 may or may not be provided, and the slightly adhesive paste layer 60 may or may not be provided.

  In addition, in the above, when there exists the slightly adhesive paste layer 60 ((c) and (d) of FIG. 2), the release paper which covers this paste layer 60 until it uses before the surface of this paste layer 60 (Not shown) is provided. The release paper may be a release sheet, and may be a desired resin or a paper processed to have a smooth surface so that peeling is easy.

  In the above description, an example in which the particle-fixing resin layer 24 forming the anti-slip particle layer 20 is different from the plastic base material layer 10 has been described, but as shown in FIGS. In addition, the particle fixing resin layer and the plastic base material layer may be composed of an integral layer 30. This layer 30 is a particle-fixing resin layer that can also function as a plastic substrate layer, and is hereinafter referred to as an anti-slip particle-fixing resin layer 30 or the like.

  The floor anti-slip sheet 1D of the vehicle transport ship shown in FIG. 3A has a particle-fixing resin layer 30 that can also function as a plastic base layer, and lacks the plastic base layer 10. It is comprised similarly to the floor surface non-slip sheet | seat 1 of the vehicle transport ship shown to (a) of FIG.

  The floor anti-slip sheet 1E of the vehicle transport ship shown in FIG. 3B further lacks the adhesive layer 5, and the particle-fixing resin layer 30 and the magnetic particle holding layer 52E of the sheet-like magnet portion 3E are directly connected. Except for the fact that it is joined to each other, it is configured in the same manner as the floor surface anti-slip sheet 1D of the vehicle transport ship of (a).

  The floor anti-slip sheet 1F of the vehicle transport ship shown in FIG. 3 (c) has the particle fixed resin layer 30F and the magnetic particle holding layer 52F of the sheet-like magnet portion 3F made of the same resin material, and the ceramic particles 52 are Except for being dispersed and held directly in a region on the surface 54 side of the magnetic particle holding layer 52F, the magnetic particle holding layer 52F is configured in the same manner as the anti-slip sheet 1E on the floor of a vehicle transport ship.

  In the anti-slip sheet 1G of the vehicle transport ship shown in FIG. 3 (d), the magnetic particles 51 are actually present in the portion 30G of the magnetic particle holding layer 52F on the surface 54 side where the ceramic particles 52 are dispersed. Except for the fact that it is not dispersed and is actually made only of the resin material of the magnetic particle holding layer 52G, it is configured in the same manner as the anti-slip sheet 1F of the floor surface of a vehicle transport ship of (c).

  Also in the above case, the coating layer 26 of the ceramic particles 22, the slightly adhesive paste layer 60 on the bottom surface 53 side of the sheet-like magnet unit 3, and the like may be further provided.

  The vehicle surface anti-slip sheet 1H shown in FIG. 3 (e) is similar to FIG. 2 (b) except that a coating layer 26 is further formed on the surface of the ceramic particles 22. (B) It is comprised similarly to the floor surface non-slip sheet | seat 1E of the vehicle transport ship. 3 (f), the floor anti-slip sheet 1J of the vehicle transport ship has a slightly adhesive layer 60 on the bottom surface 53 of the sheet-like magnet portion 3E, as in FIG. 2 (c). (E) It is comprised similarly to the floor surface non-slip sheet | seat 1H of the vehicle transport ship of (e) except the point formed.

  With respect to the floor slip prevention sheet of the vehicle transport ship configured as described above, the sheet 1 will be mainly described below by taking the floor slip prevention sheet 1 of FIG. The case of applying to the surface of the floor F of the vehicle transport ship 70 (see FIGS. 5A and 5B), that is, the anti-slip of the floor surface F1, will be described in more detail.

  In the vehicle loading parking area 71 of the vehicle transport ship 70, the anti-slip sheet 1 of the vehicle transport ship is shown on the surface F1 of the steel floor F of the vehicle transport ship 70, for example, as shown in FIG. As described above, they are arranged side by side with a desired interval in the range from about 2 to 3 cm to about 20 to 30 cm. If desired, the sheets 1 may be arranged in a close state (for example, at intervals of about 2 to 3 mm or less) so that there is practically no gap. Here, the lashing fastener 72 is a fastener for securing the vehicle to the floor F in order to prevent the vehicle from being largely moved relative to the floor F. The lashing fasteners 72 can be of different shapes and structures.

  In the example of FIG. 4A showing that there are a large number of rows arranged in the Y direction with the rectangular sheet 1 extending in the X direction, for example, the car is oriented in the Y direction. In the state, they are arranged so as to be arranged at intervals in the X direction. In that case, even if the parking position of the vehicle is slightly deviated in the X direction, the tire of the vehicle is unlikely to come off from the anti-slip sheet 1, and anti-slip is easily performed.

  However, in the example of FIG. 4A, if desired, for example, the vehicle may be arranged so as to be arranged at intervals in the Y direction with the vehicle facing in the X direction. In that case, the anti-slip sheet 1 that reliably applies a braking force to the tires of the vehicle when the vehicle is braked has a static magnetic force between the sheet magnet 3 and the steel floor F and the static magnetic force. Since the frictional force generated under the action holds the sheet over a long length range, the anti-slip sheet 1 is easily held securely in a fixed state of the steel floor F. Therefore, braking is reliably performed, and slip prevention is easily performed.

  From the viewpoint of using both the intermediate state or the advantages of both, in the example of FIG. 4A, the vehicle is parked in an oblique direction with respect to both the X direction and the Y direction. It may be.

  In addition, as shown in FIG. 4A, instead of arranging a large number of floor surface anti-slip sheets 1 in parallel at equal intervals, for example, as shown in FIG. The sheets 1 may be arranged in parallel with each other and in a different direction from the other group of sheets 1. In these cases, the direction of the seat 1 can be arranged at a desired interval in a desired direction on the floor surface F1 so as to reliably and efficiently suppress the occurrence of slip when the vehicle is running or stopped. .

  The above description is based on the assumption that the planar shape of the sheet 1 is a rectangle. However, the planar shape of the sheet 1 may be any shape other than a rectangle, and a desired shape may be determined depending on the shape. The sheets 1 are arranged at desired intervals and intervals. In addition, the sheet | seat 1 may have various different planar shapes, and in that case, you may make it arrange | position the sheet | seat of a different shape according to a space | interval and direction in a clearance gap.

  As shown in (b) of FIG. 5, not only the parking area 71 of the vehicle transport ship 70 but also at least a part of the traveling path 73 leading to the parking area 71 (typically practically the entire area) In particular, the floor surface non-slip sheet 1 is also laid on the slope (slope) portion 74 of the travel path 73.

  When laying the floor surface non-slip sheet 1 as described above, the sheet-shaped magnet is arranged so that the sheet-shaped magnet portion 3 of the floor surface non-slip sheet 1 contacts the surface F1 of the floor F in a desired direction at a desired position. What is necessary is just to arrange | position this sheet | seat 1 on the floor surface F1 under the effect | action of the attractive force of the part 3 and the steel floor F. FIG.

  When the position of the sheet 1 is not appropriate at the time of arrangement, the sheet 1 is simply peeled off from the floor surface F1 with its one end 7 as will be described later with reference to FIG. Thus, the flexible sheet 1 can be easily peeled from the floor F1 at any time (with respect to bending in the thickness direction). As shown in FIG. 7A, the end 7 may be the corner 7a or the side edge 7b (when the corner and the side edge are not distinguished from each other or generically referred to as the end). Is represented by reference numeral 7). That is, for example, the end 7 of the sheet 1 (four or four corners 7a, 7a, 7a, 7a, or a short side or side edge 7b, 7b at the end of the long side of the sheet 1). Is pinched with a finger or the like, and pulled in the direction of the arrow Ma or Mb (when not distinguished from each other or generically referred to as the peeling direction of the end portion 7, it is represented by the symbol M), and the sheet 1 is pulled to the corner portion 7 a or side edge After peeling off from 7b, the sheet 1 may be laid again at an appropriate place under the action of the static magnetic force of the sheet-like magnet portion 3. When the laying is performed again, the sheet 1 may be moved in the reverse direction of the peeling in the M direction.

  As described above, a large number of the surfaces of the steel floor F or the floor surface F1 are provided on the traveling path 73 of the vehicle V (FIG. 5A) or the parking area 71 of the vehicle V such as an automobile to be loaded. When a vehicle V such as an automobile is loaded on the vehicle transport ship 70 on which the floor surface non-slip sheet 1 is laid, as shown in FIG. 5 (a), the vehicle V temporarily enters the parking space 80 of the port. Arranged side by side. For example, when the vehicle V is placed outdoors in this way and it rains, the vehicle V and the road surface 81 get wet. When the loading of the vehicle V onto the ship 70 is started in such a wet state, the vehicle V is self-propelled and enters the vehicle transport ship 70 and travels in the ship 70 having a structure such as a multilevel parking lot. Along the road 73 ((b) in FIG. 5) and the like, the vehicle travels to each predetermined stop space or parking area 71 ((b) in FIG. 5 or (a) in FIG. 4) and stops. During this time, if the travel path 73 is prevented from slipping by the large number of floor surface anti-slip sheets 1, the vehicle V can travel to a predetermined stop space (parking area) 71 without actually slipping.

  If the road surface is wet when the vehicle V is braked or the vehicle V is going to turn a curve in the running road 73 or the parking area 71 on the way including the slope 74 ((b) of FIG. 5), the vehicle V In the case where slip is likely to occur between the road surface F1 and the road surface F1, but the floor surface anti-slip sheet 1 is laid and the anti-slip portion 2 of the anti-slip sheet 1 can perform a sufficient anti-slip function, for example, FIG. As shown in (a), the braking force J is applied to the tire 91 of the wheel 90 of the vehicle V from the floor surface non-slip sheet 1. At this time, as a reaction, a force −J is applied to the anti-slip particle layer 20 of the anti-slip part 2 of the sheet 1. On the other hand, the surface (bottom surface) 53 of the sheet-shaped magnet portion 3 of the floor surface anti-slip sheet 1 and the steel floor under the action of magnetic attraction acting between the sheet-shaped magnet portion 3 and the steel floor F. A large frictional force K acts between the surface F1 of F. Here, the maximum value of the frictional force K (maximum frictional force) can actually exceed the braking force J (that is, K> J), so that the seat 1 does not actually deviate along the floor surface F1, A braking force J can be applied to the tire 91. Therefore, the vehicle V can be stopped or bend a curve without actually causing an unexpected slip.

  Here, although the magnetic force of the magnetic material 51 forming the sheet-shaped magnet portion 3 seems to be relatively small at first glance, the magnetic material 51 of the sheet-shaped magnet portion 3 is actually in close contact with the steel floor F and Since the sum of the area regions can reach a considerable size, it is understood that the force becomes so large that it is difficult to ignore. When the vehicle V is placed on the seat 1 (assuming that the load dependency of the friction coefficient is relatively small), the weight of the vehicle V is also applied as a mutual pressing force between the magnet portion 3 and the steel floor F. become. In other words, if the area of the extended surface S (XY plane) of one sheet 1 is too small, the force acting between the sheet 1 and the steel floor F may be insufficient. Therefore, the area of the sheet 1 is preferably large to some extent, and it is not preferable to make the sheet 1 excessively small.

  Further, in a state where the sheet 1 is laid in close contact with the surface F1 of the steel floor F, for example, a force P in the Y1 direction is applied to a part of the region Q centering on the portion X1 in the X direction of the sheet 1. 6B, when a large local deformation occurs in the XY plane in the region Q around the part X1 of the sheet 1, as shown in FIG. The whole part 3 does not work effectively for slip prevention. Such a situation may occur, for example, when the length of the sheet 1 in the Y direction is short or the sheet 1 itself is soft and local deformation occurs in the region Q. Therefore, it is preferable that the length of the sheet 1 in the short side Y direction is not so short, and it is preferable that the sheet 1 has a certain degree of rigidity so that the deformation in the extending surface S hardly occurs in practice. When the roughened layer includes the anti-slip particle layer 20, the anti-slip particle layer 20 itself can impart a certain degree of rigidity to the sheet 1.

  Further, for example, as shown in FIG. 6C, the sheet 1 is deformed in the thickness direction, and a partial region Q of the sheet 1 is lifted from the floor surface F1 and is magnetically attracted in the region Q. When the force actually does not work, the sheet-like magnet portion 3 of the sheet 1 does not work effectively to prevent slipping. Such a situation may occur, for example, when the sheet 1 is soft and thin. Therefore, it is preferable that the sheet 1 has some rigidity against deformation in the thickness direction. As described above, when the roughened layer includes the anti-slip particle layer 20, the anti-slip particle layer 20 itself can impart a certain degree of rigidity to the sheet 1.

  When the sheet 1 is replaced due to wear of the anti-slip particle layer 20 of the sheet 1 or the ship 70 is renewed due to the sale of the ship 70 or other reasons, the sheet 1 shown in FIG. As shown in (b), the end 7 of each sheet 1, that is, the corner 7a or the side edge 7b is pinched with a finger or the like and pulled in the M direction. As a result, as indicated by a solid line in FIG. 7B, the sheet-like magnet portion 3 of the flexible sheet 1 can be easily removed from the floor F made of steel (with respect to bending in the thickness direction). Can be peeled off in such a short time and with a small amount of labor). In addition, after this peeling, on the surface F1 of the steel floor F, the trace in which the sheet-like magnet portion 3 is magnetically attracted does not actually remain as dirt (actually, the region is covered). The point that is less contaminated than the surrounding area becomes a trace). After peeling, after cleaning or repainting of the surface F1 of the floor F as desired, a new sheet 1 may be laid again on the floor surface F1. At this time, the new sheet 1 may be the same as the sheet 1 laid before that, or may have a different size or shape, and may be the same or different in arrangement.

  [Test example]

Finally, one test example will be described. The anti-slip particle layer 20 is made of alumina particles, and the magnetic particles 51 of the sheet-shaped magnet portion 3 are made of Fe ₃ O ₄ ferrite particles. (Width direction) about 15 cm, thickness about 1 to 2 mm) are laid on the surface of the steel sheet with an interval of about 5 to 10 cm, and the weight of 1800 kg operated at a speed of 20 km / h When the vehicle (forklift truck) was running on the seat 1 with the 15 cm width effective surface of the seat 1 being the front direction, the vehicle was braked and stopped suddenly. The braking force at the time of sudden stop is sufficiently larger than the braking force experienced by a normal vehicle V such as an automobile ((a) of FIG. 5) in a normal ship 70. The seat 1 stopped without actually being displaced. As a result, in the vehicle anti-slip sheet 1, it is possible to reliably prevent the vehicle from slipping by the anti-slip particle layer 20 while maintaining the state in which the sheet-like magnet portion 3 is magnetically attracted to the steel floor. ,found.
