Description

  The present invention relates to a floor panel panel laid on the floor of a luggage compartment in a vehicle such as a light van or a truck.

  With the diversification of consumer life in recent years, as seen in the spread of courier services and the supply of goods to convenience stores, in terms of logistics, demand for small packages or immediate delivery that delivers immediately according to orders, etc. Is growing. In addition, the packages themselves are diversified, and perishable foods such as vegetables, fruits, and seafood, or fresh flowers are often handled. In order to transport such luggage or frozen foods, a cold car equipped with a refrigeration apparatus and keeping the temperature of the luggage compartment at a low temperature is often used.

  In order to deliver small items by courier, so-called one-box type small light vans are often used. Unlike a truck with a frame, a light van is a monocoque body vehicle in which the driver's cab and the back luggage compartment are one continuous room, and usually serves as a doorway for luggage at the rear of the vehicle. There is a door. A wagon-type vehicle that is not a one-box has a luggage compartment at the rear.

  As shown in FIG. 5, a steel plate having grooves and peaks extending in the longitudinal direction of the vehicle is generally used for the floor surface 6 of the luggage compartment of the light van in order to improve rigidity. Such steel plates are also used for truck beds. For this reason, since the floor surface 6 of the luggage compartment is uneven, the stability is particularly poor when a small luggage is placed, and there is a risk of falling or the like due to the shaking of the vehicle body during the operation of the vehicle.

  Further, exhaust system parts such as an exhaust pipe and a muffler through which high-temperature exhaust gas from the engine passes are arranged at the lower part of the vehicle floor. Recent vehicle engines are equipped with an exhaust gas treatment device such as a catalyst device, and the temperature of the exhaust gas tends to rise further. However, the radiant heat from high-temperature exhaust system parts and the like is generated on the floor of the vehicle. It is transmitted and its temperature rises considerably. Heat may also be transmitted from the power transmission system parts. In light vans, the exhaust system parts are usually arranged closer to the floor than the truck, so that the temperature rise on the floor due to exhaust heat is more severe than the truck.

  Placing a plate-like floor covering on the floor of the luggage room, and improving the stability and convenience of loading the load by making the floor flat without unevenness, and preventing the transfer of heat from the floor Conventionally known. For example, it is customary to construct a floor covering by placing a wooden slat on a hot floor, stacking foamed polystyrene for heat insulation on the top of the slat, and then stacking cardboard to protect the top. ing. Japanese Utility Model Registration No. 2574668 discloses a technique in which a plurality of plastic laminates having a cardboard-like cross section are stacked to form a floor panel panel for a luggage compartment. As shown in FIG. 6, the floor panel panel is formed by sandwiching a plastic plate 9 having a recess formed between two plastic flat plates 8 and 8, and stacking a plurality of these.

On the other hand, the inventor of the present invention conducted research and development on panel materials used in vehicle luggage compartments, etc., and as a result, disclosed in Japanese Patent Application Laid-Open No. 2004-28434 has a heat insulating panel suitable for a side wall or a door of a cold car. developed. This thermal insulation panel uses two composite plates in which a plastic such as polyethylene resin is interposed between two aluminum plates or stainless steel plates, and a thermal insulation material such as polystyrene foam is sandwiched between the composite plates. Yes. This heat insulating panel is excellent in heat insulating properties and at the same time uses a metal plate having high rust prevention properties, so that it has high strength and high durability.
Utility Model Registration No. 2574668 JP 2004-28434 A

  When transporting fresh food or the like, it is necessary to prevent the temperature from rising, and a panel board with excellent heat insulation is required as a floor panel panel in the luggage compartment of a light van. In particular, light vans are easy to carry and are often used for frequent short-distance transportation. Normally, light vans are not equipped with a dedicated cooling device for luggage compartments. I want to be able to prevent the temperature rise of the luggage compartment by using the cold air of the car air conditioner.

  In consideration of the loadability of the luggage, the thickness of the floor panel must be reduced as much as possible so as not to reduce the volume and height of the luggage compartment. When styrofoam and corrugated cardboard are stacked on wooden slats to prevent heat transfer from the floor surface, the overall thickness reaches about 100 mm, the loadability of the load deteriorates, and the styrofoam and corrugated cardboard are strong and durable. It will be damaged in a short time by the work of loading and unloading luggage. The plastic floor panel disclosed in Patent Document 1 has good performance in terms of heat insulation and durability. However, plastic is relatively soft, and its surface is easily damaged when carrying and unloading luggage. When the surface is scratched, dust, microorganisms such as bacteria or fungi invade into the back, and hygiene problems may occur when transporting fresh food products.

  The heat insulating panel described in Patent Document 2 is a metal having an excellent corrosion resistance on the surface, and generally has a higher hardness than plastic. Therefore, the surface is hard to be scratched and can be easily cleaned even if dust or mold adheres. Moreover, it is excellent in strength and durability and hardly deforms even when a heavy object is loaded. Of course, since the heat insulating property is good, this heat insulating panel is also suitable as a floor panel panel for a luggage room, and this heat insulating panel is molded according to the shape of the floor surface of the luggage room. It can be considered as a plate.

  By the way, the floor panel panel needs to be fixed to the floor so as not to move due to shaking or vibration while the vehicle is running. Therefore, the floor panel plate prevents lateral movement by bringing the left and right sides of the floor panel into contact with the side walls on both sides of the luggage compartment, and also prevents vertical movement due to the frictional force between the side parts and the side wall. It is preferable to do so. One of the left and right sides of the floor panel panel may be brought into contact with one side wall of the vehicle, and padding or the like may be placed between the other side portion and the other side wall.

  However, since the surface of the heat insulating panel described in Patent Document 2 is a metal having a high thermal conductivity, when the floor panel using this is brought into contact with the side wall of the luggage compartment, the heat of the side wall is reduced. It was found that it was transmitted to the loaded luggage through the metal plate on the surface. The side walls of the luggage compartment of the vehicle are connected to the steel plate on the floor surface to transfer the heat, and the outside is also exposed to sunlight. This results in an increase in the temperature of the load loaded on the panel board. The present invention uses a heat insulating panel having a metal plate on the surface as a floor panel panel in order to increase strength and durability and prevent the occurrence of scratches on the surface. It is an object to prevent heat transfer from the side wall of the chamber.

In view of the above problems, the present invention provides a laminated board, which is a heat insulating panel having a metal plate disposed on the surface, for the purpose of enhancing the strength and durability of the floor panel and preventing the occurrence of scratches on the surface. In order to prevent the heat transfer from the side wall of the luggage compartment, a plastic cover member is provided on the side of the laminated plate. That is, the present invention
“A cover member made of a substantially rectangular laminated plate in which an upper surface and a lower surface are metal plates and a foamed plastic heat insulating material is interposed between them, and at least two opposing side portions of the laminated plate are made of plastic. Is provided. "
This is a floor panel panel for a luggage compartment of a vehicle.

  As described in claim 2, at least one of the upper and lower metal plates can be an aluminum plate, and as in claim 3, at least one of them can be a stainless steel plate. .

  According to a fourth aspect of the present invention, it is preferable that the cover member is formed in a U-shaped cross section and is provided so as to cover an end portion of the laminated plate and upper and lower surface edge portions.

  A composite plate in which a plastic layer is interposed between two metal plates can be disposed on at least one of the upper and lower portions of the laminated plate as described in claim 5.

  According to a sixth aspect of the present invention, the laminate plate has a lateral length that is substantially the same as a lateral length of the floor surface of the luggage compartment, and is provided with two cover members. It is preferable that the side portion is placed in contact with the side wall of the luggage compartment.

  The laminated board in the floor panel panel of the present invention is a metal whose surface is excellent in corrosion resistance. Since metal is generally harder than plastic, the surface is less likely to be scratched, and even if dust or mold adheres, it can be easily washed and removed. Therefore, it is excellent in appearance and easy to keep clean, and is suitable for transporting fresh food and flowers. Heat from the floor surface of the luggage compartment is blocked by a heat insulating material made of foamed plastic interposed between them and is not transmitted to the surface metal plate.

  A cover member made of plastic is provided on at least two opposing side portions of the laminate. Therefore, even if a metal having a high thermal conductivity is employed on the surface, the cover member can shield the heat, and the floor panel panel can be laid in contact with the side wall of the luggage room having a high temperature. As a result, the floor panel does not move due to shaking or vibration while the vehicle is running, and the stability of the luggage loaded on the top is improved. Furthermore, although the heat insulating material interposed in the laminated board of the present invention is a brittle one made of foamed plastic, it is protected by a cover member, so that the heat insulating material may be damaged even if the floor panel panel is brought into contact with the side wall. Is prevented.

  A technique for improving the appearance and ensuring safety during handling by providing a U-shaped “edge” on the side surface of the floor panel panel is disclosed in Patent Document 1 described above. However, since the floor panel panel of Patent Document 1 is made of plastic and does not have a metal plate disposed on the surface, the surface is easily damaged, and the problem of heat transfer from the side wall does not occur. The cover member of the floor panel panel of the present invention has a specific effect of blocking heat transfer when a metal plate is arranged on the surface and further preventing damage to the heat insulating material.

  In the inventions of claims 2 and 3, it is apparent that the effects accompanying the material of the aluminum plate or the stainless steel plate occur. When the cover member is formed in a U-shaped cross section as in claim 4, there is an effect that the cover member is difficult to drop off, and in the invention of claim 5, there is an effect that the heat insulation is further enhanced. In the invention of claim 6, since the cover members on both sides of the floor panel panel are in close contact with the side walls of the luggage compartment of the vehicle, the convenience of loading the luggage is improved, and the stability of the luggage during transportation is improved. Can be made.

  Hereinafter, the floor panel panel of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a floor panel panel according to a first embodiment of the present invention, FIG. 2 is a perspective view of the floor panel panel, and FIG. 3 is laid on the floor surface of a light van luggage compartment. Shows the state.

  In the floor panel panel of the first embodiment, a composite plate in which a plastic layer 2 such as polyethylene resin is interposed between two metal plates 1 and 1 is arranged on the upper surface and the lower surface, and a foamed plastic heat insulating material is interposed between them. 3 is used. As the metal plate 1, an aluminum plate or a stainless steel plate having high corrosion resistance is used. The thickness of the metal plate 1 is about 0.1 to 0.4 mm and is a relatively thin plate, and the thickness of the composite plate including the intermediate plastic layer 2 is about 1 to 4 mm. For example, styrene foam and urethane foam are used as the heat insulating material 3 of foamed plastic, and the thickness thereof is appropriately adjusted according to the required heat insulating performance or the use situation of the floor panel panel.

  As is clear from the perspective view of FIG. 2, the floor covering panel of the present invention has a substantially rectangular plane in accordance with the floor surface 6 of the luggage compartment of the vehicle, and is located on both lateral sides, that is, in the longitudinal direction of the vehicle. A cover member 4 is provided on two extending side portions. The cover member 4 is made of plastic such as polyethylene resin, and is attached to the laminated plate by means such as adhesion. In the first embodiment shown in FIG. 1, the cross section is formed in a U-shape and covers the upper and lower surface edges as well as the side portions of the laminate. In some cases, only a side portion of the laminated plate can be covered with a cover member 4 having a plate-like cross section, as in a cover member in a second embodiment of FIG. 4 described later. Further, the cover member 4 may be attached not only to the side portions on the side of the floor panel plate but also to the side portions on the front and rear sides of the vehicle so as to cover the entire side portion of the laminated plate.

  The surface of the floor panel of the present invention is a metal plate 1 having corrosion resistance such as an aluminum plate or a stainless steel plate. Its hardness is higher than that of plastic, so it is hard to get scratches when loading luggage on top. If there is no scratch on the surface of the floor panel panel, even if dirt, mold, bacteria, etc. adhere, it does not enter the back part and can be easily removed by washing. For this reason, the floor panel panel of the present invention is improved in appearance and can be kept clean, and is particularly suitable for transporting fresh food products.

  Further, the floor panel panel of the present invention is manufactured according to the floor surface of the luggage compartment of the vehicle, and as shown in FIG. 3, the cover member 4 is in contact with both side walls 7 and 7 of the luggage compartment of the vehicle. Laying on the floor. Therefore, it is possible to prevent the floor panel plate from rattling and moving due to the shaking or vibration of the vehicle during transportation, and stable transportation of the luggage becomes possible. However, even in a luggage compartment of a vehicle having a wider width than the floor panel, one cover member 4 is brought into contact with the side wall and a padding is placed between the other cover member 4 and the side wall. Floor covering panels can be used.

  Even if both sides of the floor panel panel are brought into contact with both side walls 7 and 7 of the luggage compartment, the cover panel 4 is provided on the floor panel panel of the present invention. 1 does not contact the side wall directly. Thereby, it can avoid that the heat of the side walls 7 and 7 is transmitted to the load loaded via the metal plate 1 on the surface. The heat insulating material 3 laminated in the middle of the floor panel panel is a fragile material made of foamed plastic such as foamed polystyrene. However, the cover member 4 of the present invention protects the heat insulating material 3 and comes into contact with the side wall 7. Effective in preventing damage. Furthermore, there is also an effect of preventing a human body from being damaged by the sharp edge portion of the metal plate 1 when installing and removing the floor panel.

  In the floor panel panel of the present invention, heat from the floor surface 6 of the vehicle is blocked by the heat insulating material 3 such as polystyrene foam or the plastic layer 2. Since the heat from the side wall of the luggage compartment is shielded by the cover member 4, the floor panel panel of the present invention has high heat insulation even if it is relatively thin. As a result of the experiment, the floor panel board of the present invention has a performance equivalent to that of a heat insulation means having a thickness of about 100 mm, in which an insulating material of foamed polystyrene is placed on a wooden slat and further corrugated cardboard is laminated. It was confirmed to be obtained with

  FIG. 4 shows a second embodiment of the floor panel panel of the present invention. In this floor panel panel, a composite plate comprising metal plates 1 and 1 and an intermediate plastic layer 2 is placed on the lower surface as in the first embodiment, but one metal of aluminum or stainless steel is placed on the upper surface. A plate 5 is arranged. Moreover, the cover member 4 attached to both side parts is formed in plate shape, and is fixed by means, such as adhesion | attachment, so that only a side part may be covered. The thickness of the metal plate 5 is about 0.5 to 3 mm.

  The floor panel panel of the second embodiment has a slightly lower thermal insulation performance than that of the first embodiment because the upper surface is a single metal plate. However, effects such as the point that the heat transfer from the side surface can be prevented by the cover member 4 are the same as the floor panel panel of the first embodiment. Since a single metal plate is cheaper than a composite plate, the floor panel panel of the second embodiment is more advantageous in terms of cost. Since the thickness of the metal plate is large, it is superior to that of the first embodiment in that the scratches generated when loading the luggage do not reach the inner surface. It is obvious that the cover member 4 can have the same shape as the cover member of the first embodiment having a U-shaped cross section.

  As described above in detail, the floor panel panel of the present invention uses a laminated plate having a metal plate on the surface, and increases the strength and durability and prevents the occurrence of scratches on the surface. A plastic cover member is provided. Therefore, the present invention can be applied not only to a light van luggage room but also to a luggage room such as a truck. Moreover, it is natural that the thickness of each material to be laminated can be appropriately set according to the application, and the above-described dimensions and the like are merely examples.
