Description

  The present invention relates to a transfer plate, and more specifically, for example, a flat slope is formed when passing a step in a wheelchair or the like, or a continuous flat passage is formed when passing a groove or a recess. It is related to a portable transfer board that ensures smooth movement.

  In recent years, elevators and escalators have been installed as barrier-free measures in public facilities, etc. In addition, there are cases where slopes are created as detours along the stairs, making it easy to access with wheelchairs, etc. ing. Furthermore, in places where it is necessary to ascend and descend only by stairs, a wheelchair stair lift that goes up and down along the stairs may be installed near the wall. Because social infrastructure has been gradually developed in this way, for example, when people with disabilities or elderly people on wheelchairs go out, these elevators, escalators, slopes as detours, Or it can pass without danger using a stair lift for wheelchairs.

  However, even though social infrastructure development as described above has progressed, there are many steps that have not been developed yet, such as steps between sidewalks and roadways, steps between bus entrances and exits, and when getting on and off trains and trains. It is also true that the steps and gaps between the vehicle and the platform are hindering wheelchair traffic. Recently, when a wheelchair gets on or off a train or a train, or gets on or off a bus, the wheelchair can be used by using a transfer board (sometimes referred to simply as a slope) that is always provided at the boarding station or bus. To get on and off safely. Patent Document 1 discloses an invention of a “portable slope” used as such a transfer plate. The invention disclosed in Patent Document 1 attaches a non-slip material formed by connecting hard or soft chip materials or both with a binder to the surface of two plate materials made of reinforced plastic. It was set as the structure which connected the board material of the sheet | seat with the sheet | seat material which consists of a woven fabric or a nonwoven fabric.

  However, in the portable slope disclosed in Patent Document 1, the sheet material is attached to the side surface of the plate material to connect the plate materials, but while the folding and unfolding of the plate material are repeated, the sheet The material may deteriorate, the sheet material may be partially damaged, or the sheet material may be peeled off from the side surfaces of the plate material. There was a problem that there was a risk that it could not be secured. In the portable slope disclosed in Patent Document 1, when using a wheelchair to get on and off a train across a step or gap between a vehicle and a platform when getting on and off a train or a train, the position on the platform to get into the vehicle is When it is a place with poor visibility from the conductor, or when the lighting effect at night is somewhat bad, it is difficult for the conductor and other station staff in the distance to recognize getting on and off the wheelchair using the portable slope, There is also a problem that even though the wheelchair is getting on and off, there is a possibility that the driver may notify the conductor of the door closing operation of the vehicle by the conductor or the door closing instruction by the station staff.

  Moreover, in the portable slope disclosed in Patent Document 1, a woven fabric or a non-woven fabric is used for a sheet connecting two plate materials, and the fibers forming the woven fabric or the non-woven fabric include polyamide fibers, polyester fibers, The required strength is ensured by using any one of polyvinyl alcohol fibers, etc., and the sheet connecting two plate materials is of a very special structure, so it is not easy to obtain, Therefore, there is a problem that the price is high, which increases the price of the portable slope. Tools for securing traffic such as wheelchairs need to be safe as much as possible, and at the same time are preferably inexpensive. In that sense, the portable slope of the invention disclosed in Patent Document 1 Was inappropriate.

  An object of the present invention is to solve such a conventional problem, and it is safe to pass a wheelchair or a person with a physical disability through a step, a groove, or a recess. It is to provide a transfer plate that can secure the above. Another object of the present invention is to provide a transfer plate that can easily recognize the state even from a distance when passing a wheelchair or a person with a physical disability.

  The present invention includes a plurality of thick plate members having at least a flat surface and a side surface connected to the surface, and each of the plate members is arranged with the side surfaces facing each other to form a step, a groove, or a recess. It is a passing plate that is spanned to a place and is used as a passage, and the side surfaces facing each other of the plate members are connected to each other by a hinge so as to be foldable. The first tape and the second tape are made of a synthetic resin having flexibility, and the first tape is formed between the side surfaces with the side surfaces of the adjacent plate members facing each other.

  According to the transfer plate according to the present invention, the first tape and the second tape made of flexible synthetic resin for connecting the plate members arranged so that the flat side surfaces face each other with a gap are provided on both plates. Since it is affixed across the gap between the opposing side surfaces of the member, a joint where the two tapes are bonded to each other is formed in the gap as a connecting portion and hinge portion. The connecting and hinge portion is very strong and durable because the first tape and the second tape are bonded together. As a result, the first tape and the second tape connecting the plate members are commercially available. Even if it uses an adhesive tape, it can form a connecting part and hinge part that can withstand use sufficiently, and even if the folding and unfolding of those plate members are repeated, the tape will not peel from those plate members, The connection of these plate members is not inadvertently released, and the safety of passage through the transfer plate can be ensured. In addition, the transfer plate can be made very light and easy to carry.

  Furthermore, according to the transfer plate of the present invention, since the second tape is attached from the side surfaces to the back surface of both plate members, when connecting both plate members with the second tape, greater connection strength is obtained. Can be obtained. In addition, since the first tape and the second tape connecting the adjacent plate members are provided with a large number of reinforcing fibers extending in the direction crossing the gap, the strength of each tape itself is increased. The connection strength of the plate members can be increased. Furthermore, in addition to the above-mentioned reinforcing fibers, the first tape and the second tape that connect adjacent plate members contain a large number of reinforcing fibers extending in the direction along the gap, and are attached to both plate members.

  Hereinafter, the transfer plate of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings. FIG. 1 is a plan view showing a transfer plate 10 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the transfer plate 10 of FIG. FIG. 3 is a partial enlarged cross-sectional view showing an A portion of FIG. 2 in an enlarged manner. The transfer plate 10 includes three plate members 11, 12, and 13 formed of fiber reinforced plastic (FRP). These three plate members 11 to 13 are arranged so that their longitudinal axes are parallel to each other and are bridged over a step, a groove, etc. For example, it is somewhat difficult for a wheelchair or a person walking with a person with a physical disability. A certain elderly person can pass through the three plate members 11 to 13 arranged side by side safely, and at that time, the thickness and the size have a strength that does not cause breakage but also large deflection. ing.

  As apparent from FIGS. 1 and 2, each of the plate members 11 to 13 constituting the transfer plate 10 according to this embodiment includes a front surface 11a, 12a, 13a and a back surface 11b, 12b, 13b, and an opposite side surface 11c. , 11d, 12c, 12d, 13c, 13d, and a rectangular parallelepiped having a predetermined thickness, including six faces of opposing end faces 11e, 11f, 12e, 12f, 13e, 13f. In this embodiment, these plate members 11 to 13 are formed in substantially the same shape and size, and at least the front surfaces 11a, 12a, and 13a and the back surfaces 11b, 12b, and 13b are formed flat (smooth). Moreover, the side surfaces 11d and 12c and the side surfaces 12d and 13c facing each other at least in the adjacent plate members 11 to 13 are also formed flat (smooth).

  These three plate members 11 to 13 face each other so that the side surfaces 11c, 12c, 12d, and 13c face each other, and a slight gap portion 14 is formed between the side surfaces 11c, 12c, 12d, and 13c. The first tape 15 and the second tape 16 are made of a synthetic resin having flexibility in a state of being arranged close to each other. The connection structure between the plate members 11 to 13 using the first tape 15 and the second tape 16 will be described in detail when the two plate members 11 and 12 are connected. The first tape 15 is shown in FIG. As is clear from the enlarged view of FIG. 2, the side surface 11d of the plate member 11 and the side surface 12c of the plate member 12 are bonded to the front surfaces 11a and 12a of the both plate members 11 and 12 across the gap 14 formed when the side surfaces 12c of the plate member 12 face each other. Affixed with an adhesive or adhesive.

  The second tape 16 is attached to the side surfaces 11d and 12c of the two plate members 11 and 12 facing each other at the gap portion 14 with an adhesive or an adhesive, and the second tape 16 is lateral to the width direction. The portions 16a and 16b reach the back surfaces 11b and 12b of the plate members 11 and 12 and are attached with an adhesive or an adhesive. In the gap portion 14, the first tape 15 and the second tape 16 are bonded to each other. 3 and 4, a portion where the first tape 15 and the second tape 16 are joined to each other at the gap portion 14 is denoted by reference numeral 17.

  A method of attaching the tapes 15 and 16 when connecting the two plate members 11 and 12 with the first tape 15 and the second tape 16 made of a synthetic resin having flexibility will be described with reference to FIGS. As shown, the adjacent plate members 11 and 12 face each other so that the respective side surfaces 11d and 12c face each other, and are arranged close to each other so that a slight gap 14 is formed between the respective side surfaces 11d and 12c. . The first tape 15 is bonded to the surfaces 11a and 12a so as to straddle the gap 14 between the side surfaces 11d and 12c and along the gap 14 in the length direction of both plate members 11 and 12. Affixed with an adhesive or adhesive. Next, as shown in FIG. 4, the two plate members 11 and 12 temporarily connected by the first tape 15 are swung as shown by an arrow 18 in FIG. And folded so that the surfaces 11a and 12a of the two plate members 11 and 12 face each other.

  When the two plate members 11 and 12 temporarily connected by the first tape 15 are folded so that the surfaces 11a and 12a face each other, the side surface 11d that faces each other as shown in FIG. , 12c are located on the same plane. Therefore, the second tape 16 is attached to both side surfaces 11d and 12c with an adhesive or a pressure-sensitive adhesive over the length direction of the side surfaces 11d and 12c so as to straddle the gap between the facing surfaces 11a and 12a. It is done. As a result, the second tape 16 is affixed to the both side surfaces 11d and 12c of the two plate members 11 and 12, and is affixed to the surfaces 11a and 12a across the gap 14 at the part crossing the gap 14. As a result, the joint portion 17 between the two tapes 14 and 15 is formed in the gap portion 14.

  The joint 17 not only connects the two plate members 11 and 12, but also spreads so that the surfaces 11a and 12a become substantially continuous planes as shown in FIG. 1 and FIG. As shown in FIG. 4, the plate members 11 and 12 function as pivot centers, that is, hinge portions when the surfaces 11a and 12a are folded to overlap each other. The connecting portion also serving as the hinge portion is very strong as a result of the first tape 15 and the second tape 16 being joined to each other.

  By the way, the second tape 16 has a gap between the surfaces 11a and 12a when the transfer plate 10 is folded so that the surfaces 11a and 12a of the plate members 11 and 12 face each other as shown in FIG. Has a width dimension larger than the total width dimension W of both side surfaces 11d and 12c located on both sides of the surface. Therefore, the side portions in the width direction of the second tape 16 attached to the side surfaces 11d and 12c across the gap between the surfaces 11a and 12a by the adhesive or the adhesive over the length direction are the plate members 11. , 12 protrude from the side surfaces 11d, 12c. The protruding side portions in the width direction, that is, the tape portions 16a and 16b are folded back to the back surfaces of the plate members 11 and 12 and attached to the back surfaces 11b and 12b.

  The first tape 15 and the second tape 16 that connect the two plate members 11 and 12 contain a large number of reinforcing fibers (threads) 19 extending in the direction crossing the gap 14, that is, in the width direction of the tape (see FIG. (See FIG. 1). If a large number of reinforcing fibers 19 extending in the width direction are inserted into the tapes 15 and 16 in this way, the strength against the tensile force in the width direction of the tapes 15 and 16 is increased, so that the two tapes 15 in the gap portion 14 are increased. , 16 can be further strengthened, and the durability of the connecting action and hinge action of the two plate members 11, 12 can be further improved. Further, when a large number of reinforcing fibers (threads) 20 extending in the direction extending along the gap 14, that is, in the length direction of the tapes 15 and 16, are inserted into the first tape 15 and the second tape 16 (see FIG. 1), Since the tensile strength of the tape itself is further increased, the strength of the joint portion 17 formed in the gap portion 14 is further increased.

  By the way, as a tape in which the warp and weft for reinforcement are put in the length direction and the width direction orthogonal thereto, for example, what is called a cloth adhesive tape that has been pre-coated with an adhesive on one side and wound up is used. Various commercially available tapes can be used as a starting point. In the transfer board 10 according to the above-described embodiment, for example, a strong tape (manufactured by Nitto Denko CS System Co., Ltd.) obtained by applying an adhesive to a polyester film using a polyester nonwoven fabric as a reinforcing material is used as the first tape 15 and the second tape 16. Can be used as Of course, other commercially available cloth adhesive tapes can also be used.

  As described above, the transfer plate 10 according to this embodiment can connect the three plate members 11 to 13 with the first tape 15 and the second tape 16 and can be folded using the joint 17 of both the tapes 15 and 16 as a hinge. It is configured. The folding at that time is preferably bellows, in other words, an accordion for ease of carrying or storage when not in use. In order to be able to fold in such a bellows shape, the arrangement structure of the first tape 15 and the second tape 16 connecting the plate members 12 and 13 located respectively in the middle and the right side in FIG. As shown in FIG. 3, the first tape 15 and the second tape 16 that connect the plate members 11 and 12 located on the left side and the middle are differently attached.

  That is, in order for the transfer plate 10 formed by connecting the three plate members 11 to 13 to be folded in a bellows shape with the joint portions 17 of the plate members 11 to 13 as hinges, for example, As in the embodiment, the front surfaces 11a and 12a of the plate members 11 and 12 positioned on the left side and the middle as viewed in FIG. 1 are overlapped, and the back surfaces 12b of the plate members 12 and 13 positioned on the middle and the right side, respectively. 13b needs to be folded so that they overlap each other. For this purpose, when the first tape 15 and the second tape 16 that connect the plate members 12 and 13 positioned at the middle and the right side are connected, the plate members 11 and 12 that are positioned at the left side and the middle are connected, respectively. It must be the opposite of pasting.

  Specifically, as is apparent from FIG. 1, when the plate members 12 and 13 positioned at the middle and the right side are connected by the first tape 15 and the second tape 16, the first tape 15 is the plate member 12. The side surface 12d of the plate member 13 and the side surface 13c of the plate member 13 are bonded to the back surfaces 12b and 13b of the plate members 12 and 13 with an adhesive or an adhesive across the gap 14 formed. The second tape 16 is attached to the side surfaces 12d and 13c of the two plate members 12 and 13 facing each other at the gap portion 14 with an adhesive or an adhesive, and further, the side of the second tape 16 in the width direction. The tape portions 16a and 16b, which are portions, reach the surfaces 12a and 13a of the plate members 12 and 13 and are attached with an adhesive or an adhesive. In the gap portion 14, the first tape 15 and the second tape 16 are bonded to each other. Thus, when the location connected by each tape 15 and 16 becomes multiple, the 1st tape 15 will be affixed alternately on the surface side and back surface side about an adjacent connection location.

  Further, a light emitting device 21 is attached to the transfer plate 10. Specifically, the light emitting device 21 is shown in FIG. 1 among the three plate members 11 to 13 connected to each other by the first tape 15 and the second tape 16 so as to be folded in a bellows shape as described above. It is provided in the outer surface 11c, 13d in the plate member 11 and the plate member 13 which are located in the outermost side. Since the light emitting device 21 attached to the outer side surfaces 11c and 13d of the two outermost plate members 11 and 13 and the mounting structure thereof are completely the same, only the plate member 11 will be described, and the plate member 13 will be described. The light emitting device 21 attached to the outer side surface 13d and the mounting structure thereof are omitted. As is clear from FIG. 5 showing the B portion shown in FIG. 2 in an enlarged manner, the outer surface 11c of the plate member 11 has a substantially U-shaped cross section in the length direction (passage direction) of the plate member 11. A notched recess 22 is formed.

  The light emitting device 21 includes a substrate 24 to which a number of light emitting diodes 23 are attached. The substrate 24 has a long and narrow shape that can be stored in the recess 22. A large number of light emitting diodes (LEDs) are arranged in a line at substantially equal intervals along the entire length of the substrate 24 as shown in FIG. Printed wiring (not shown) for energizing each light emitting diode 23 is formed on the back surface of the substrate 24. Such a board | substrate 24 is being fixed to the bottom face in the inside of the recessed part 22 by a suitable means.

  The substrate 24 described above is disposed in almost the most part of the recess 22 formed on the outer surface 11c of the plate member 11, but the space in the recess 22 remaining at one end in the length direction is shown in FIG. As shown in FIG. 2, a battery 25 for supplying power to each light emitting diode 23 is accommodated and fixed to the bottom surface of the recess 22 in a detachable manner. As the battery 25, since the power consumption of the light emitting diode 23 is very small, a commercially available button battery, a rechargeable small-sized lithium battery, or the like can be used. The substrate 24 with the light emitting diode 23 attached thereto is attached in the recess 22 formed in the outer surface 11c of the plate member 11 and the battery 25 is attached to a predetermined position in the recess 22 before the recess. It is also preferable to close 22 with a transparent cover (not shown) formed of acrylic resin or the like. That is, it is preferable that this cover is detachably attached so as to close the recess 22 so as to be flush with the outer surface 11 c of the plate member 11.

  A switch device 26 is attached to the plate member 11 in the vicinity of the battery 25. The switch device 26 is connected to an electric wire 27 that forms the power supply circuit so as to open and close a power supply circuit that connects the battery 25 and a printed wiring formed on the back surface of the substrate 24. The switch device 26 can use a known push button switch, slide switch, or various similar types of switches. In addition, the electric wire 27 forming the power supply circuit has a thin hole formed on the surface or side surface of the plate member 11 made of fiber reinforced plastic (FRP), and the electric wire 27 is inserted into the hole to thereby insert the electric wire 27 into the plate member 11. Can be wired.

  Next, the usage method of the transfer board 10 of embodiment mentioned above is demonstrated. The transfer plate 10 has three plate members 11 to 13 folded in a bellows shape with the joint portion 17 as a hinge portion and stored in an appropriate storage location. When such a transfer board 10 is used, for example, when a wheelchair is loaded onto a train from the platform, or vice versa, the station staff can remove the folded transfer board 10 from the storage location. It is carried to a predetermined position of the platform, spreads in a state as shown in FIG. 1, and is bridged between the platform and a predetermined entrance where the door of the train stopped at the platform is open. At that time, the station staff turns on the switch device 26 attached to the transfer plate 10 to supply power from the battery 25 to the light emitting diodes 23 of the light emitting device 21, and turns on these diodes 23. Thereafter, as shown in FIG. 6, the station staff pushes the wheelchair 32 and gets on the train from the platform as the passing plate 10 or goes down from the train to the platform.

  When the wheelchair 32 passes the transfer board 10, the load of the wheelchair 32 acts on the plate members 11 and 13 on which the wheel of the wheelchair 32 rides in the direction from the front surface 11a and 13a to the back surface 11b and 13b. The force enough to tear 17 does not act on the joint 17. Therefore, the joint portion 17 is not damaged by the passage of the wheelchair 32. In the transfer plate 10, since the light emitting diodes 23 of the light emitting device 21 are lit on the outer surfaces 11c and 13d of the plate members 11 and 13 located outside of the plurality of plate members 11 to 13 as described above, The train conductor can easily see the light of the light-emitting diode 23 from a distance even during the daytime as well as at night, and as a result, it can be easily confirmed that the transfer board 10 is used.

  In particular, in the light emitting device 21 attached to the outer side surfaces 11c and 13d of the plate members 11 and 13, a large number of the light emitting diodes 23 constituting the light emitting device 21 are formed from the inside of the recess 22 formed on the side surface 11c side of the plate member 11. Is attached so as to irradiate light toward the direction, and when the transfer plate 10 is viewed from a distance, the light radiated from the side surface 11c or the side surface 13d of the plate member 11 surely enters the eyes, and as a result. The presence of the cross board 10 can be confirmed with certainty.

  After the boarding / alighting of the wheelchair 32 is finished using the transfer board 10, the station staff turns off the switch device 26 to cut off the power supply to the light emitting device 21 and turns off the light emitting diode 23. Thereafter, the station staff folds the plate members 11 to 13 so as to overlap each other with the joint portion 17 connecting the plate members 11 to 13 as a hinge portion, and returns to the storage place for storage.

  In the transfer plate 10 of the embodiment shown in FIGS. 1 to 6, a switch device 26 that turns on and off the light emitting diodes 23 of the light emitting device 21 installed on the outer surfaces 11 c and 13 d of the outer plate members 11 and 13 is a transfer plate. 10 is a so-called manual operation that is performed by the operation of the person using the device 10, but if such a manual switch device 26 is used, the operation may be forgotten. In order to prevent this, it is preferable to embed a limit switch 28 in the side surface 11d of the plate member 11 as shown in FIG. 7 instead of the manual switch device 26. That is, the limit switch 28 used here includes a plunger (actuator) 28a. When the plunger 28a is pushed in, the movement of the plunger 28a is transmitted to a built-in micro switch (not shown) to close the power supply circuit. Such a switch itself is a known one.

  The plunger-type limit switch 28 is embedded in the plate member 11 so that the plunger 28 a protrudes from the side surface 11 d of the plate member 11. That is, the limit switch 28 is embedded so that the plunger 28a protrudes from the side surface 11d before the second tape 16 connecting the plate members 11 and 12 is attached to the side surfaces 11d and 12c. A hole is made at a predetermined position, and the plunger 28a is pasted from the hole so as to be exposed to the outside. The micro switch of the limit switch 28 is connected by a wire 27 to a power feeding circuit that feeds power from a battery 25 to a printed wiring formed on the back surface of the substrate 24 in the light emitting device 21. The side surface 12c of the plate member 12 facing the side surface 11d of the plate member 11 is made of a thin metal plate or a resin plate at a position where the plunger 28a abuts when the transfer plate 10 is spread as shown in FIG. A relatively hard contact plate 29 is attached so that when the transfer plate 10 is spread, the opposing side surface 12c of the plate member 12 gives a force to reliably push it into the plunger 28a.

  By using such a limit switch 28, when the transfer plate 10 is used, the light emitting device 21 is automatically switched on just by opening the transfer plate 10, and when the transfer plate 10 is folded after use, the switch is automatically turned off. Therefore, forgetting to turn on or forgetting to turn off does not occur, and the light emitting device 21 can be reliably turned on and off.

  FIG. 8 shows a part of the transfer plate 10 in which a magnet-type limit switch 30 is embedded in the side surface 11 d of the plate member 11 instead of the plunger-type limit switch 28. The magnet-type limit switch 30 includes, for example, an N-pole movable magnet (actuator) 30a on its end face, and transmits the movement of the magnet 30a to a built-in microswitch to turn on and off the contact. When this magnet-type limit switch 30 is used, another magnet 31 having an S pole or an N pole is embedded in the side surface 12 c of the opposing plate member 12. Thus, when the transfer plate 10 is unfolded as shown in FIG. 1 during use, the side surface 12c of the plate member 12 approaches the side surface 11d of the plate member 11, and the magnet 31 embedded in the side surface 12c. Is attracted to or repelled by the magnet 30a of the limit switch 30, and the microswitch is activated by this movement. Since such a magnet-type limit switch 30 is already known, details of its structure are omitted.

  The advantage of using such a magnet-type limit switch 30 is that the actuator for operating the built-in microswitch is a magnet 30a that moves by magnetic force, and the magnet 31 also moves the magnet 30a. Since the side surface 11d of the plate member 11 in which the switch 30 is embedded and the side surface 12c of the plate member 12 in which the magnet 31 is embedded can be completely covered with the second tape 16, the plate member 11 and the plate of the second tape 16 are covered. The adhesive strength, that is, the attachment strength to the member 12 is not lowered.

  In the transfer plate 10 according to each embodiment described above, the planar shape of each plate member 11 to 13 is rectangular as is apparent from FIG. 1, but the present invention is not limited to such a shape, You may form the outer edge part of the board members 11 and 13 located in the outer side in the shape curving slightly. Moreover, it is also preferable to provide anti-slip means (not shown) when the wheelchair 32 passes on the surfaces 11a to 13a of the plate members 11 to 13. Such anti-slip means includes, for example, a thin anti-slip material made of a rubber sheet or the like attached to almost the entire surface 11a to 13a of each plate member 11 to 13, or a rubber band member as a plate member. It can be configured by adhering to the surfaces 11 a to 13 a of 11 to 13 a by arranging them at equal intervals in the longitudinal direction. Further, when the plate members 11 to 13 are made of fiber reinforced plastic, it is possible to form anti-slip means by directly forming innumerable minute protrusions on the surface thereof.

  Further, in the transfer plate 10 according to each of the above-described embodiments, as is apparent from FIG. 1, the three plate members 11 to 13 have the opposite side surfaces 11 d and 12 c and the opposite side surfaces 12 d and 13 c. Although it was connected by the 1 tape 15 and the 2nd tape 16, the transfer board 10 of this invention is not limited to these embodiment, Four or more board members may be sufficient.

  As described above, according to the transfer plate 10 of the present invention, the thickness includes at least the flat surfaces 11a, 12a, 13a and the side surfaces 11c, 11d, 12c, 12d, 13c, 13d connected to the surfaces 11a, 12a, 13a. A plurality of plate members 11 to 13 are connected in a state where their respective side surfaces are opposed to each other, and the light emitting device 21 is attached to the outer surface of at least the outermost plate members 11 and 13 and in use. Since the light emitting device 21 is turned on, it is very safe because it can be easily confirmed that the wheelchair is being passed by using the transfer plate 10 even from a distance.

  Further, according to the transfer plate 10 of the present invention, the plate members 11 to 13 constituting the connecting plate 10 are connected by the first tape 15 and the second tape 16, and are used as hinges when folded in use and not in use. Since the transfer plate can be manufactured very lightly, even if the light emitting device 21 or the like is attached, the conventional transfer plate and its weight do not become particularly heavy, and there is no hindrance to carrying.

  Furthermore, the connection part and hinge part which can fully be used can be formed from the 1st tape 15 which connects the board members 11-13, and the 2nd tape 16, and folding and unfolding of these board members 11-13 are carried out. Even if it repeats, since the tapes 15 and 16 do not peel from the plate members 11 to 13, the connection of the plate members 11 to 13 is not inadvertently released, Safety can be ensured.
