  The present invention has been made in view of the present situation, and provides a portable slope in which light emitted from a slope in use is visually recognized from a wide range, and wheelchairs and the like can be effectively prevented from being removed. It is aimed.

The portable slope according to the present invention is:
A plurality of aligned plate-like members;
A derailment prevention wall projecting from the outside of the plate-like member disposed at both ends;
And a light emitting device provided on the anti-derailing wall,
Adjacent plate-like members are connected to each other so as to be foldable.

  According to such a portable slope, wheel removal of a wheelchair or the like that moves on the upper surface is prevented, and light from the light emitting device can be visually recognized from a wide range.

  The light emitting device preferably includes a light emitting element and a storage battery as a power source for the light emitting device.

  Preferably, the derailment prevention wall is formed along the outer edge of the plate-like member, and the light emitting element of the light emitting device is attached along the longitudinal direction of the derailment prevention wall.

  It is preferable that at least one end side of the outer edge of the plate-like member is provided with an oblique passage portion in which the above-described wheel removal preventing wall is not formed.

  The portable slope according to the present invention makes it possible to prevent wheelchairs from being removed, to reduce the weight of the slope itself, and to expand the visible range during use.

FIG. 1 is a plan view showing an embodiment of a portable slope according to the present invention. FIG. 2 is a side view of the portable slope of FIG. FIG. 3 is a front view of the portable slope of FIG. FIG. 4 is a perspective view showing a part of the anti-derailing wall and the light emitting device in the portable slope of FIG.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  A portable slope (hereinafter also simply referred to as a slope) 1 shown in FIGS. 1 to 4 includes three plate-like members 2. Each plate-like member 2 has a rectangular shape. The plate-like members 2 are connected in a state of being aligned in a row. Adjacent plate-like members 2 are connected by a sheet member 3 or the like so as to be foldable. The number of plate-like members 2 is not limited to three. As a connection means, it is not limited to the sheet | seat member 3, Various hinges can be employ | adopted. Handles 16 for carrying are attached to the outer surfaces of the plate-like members 2L and 2R arranged at the left and right ends.

  The plate-like member 2 is formed, for example, by press-molding a core material made of foamed polyurethane around a prepreg in which carbon fiber and glass fiber are impregnated with a resin. The material of the plate-like member 2 is not limited to such a material, and for example, an aluminum alloy or the like may be used. It is preferable that a rubber sheet or the like is stuck on the surface of the plate-like member 2 to prevent slippage. As the sheet member 3, a nylon cloth or the like is used. Nylon is adopted as the material of the handle 16. The above materials are examples and are not limited to these.

  On the outer edges of the upper surfaces of the plate-like members 2L and 2R arranged at the left and right ends, a derailment prevention wall 4 projects. The derailment prevention wall 4 is formed along the outer edges of the plate-like members 2L and 2R. The derailment prevention wall 4 may be formed integrally with the plate-like members 2L and 2R. Alternatively, as a member different from the plate-like members 2L and 2R, the plate-like members 2L and 2R may be attached by rivets or the like. In the present embodiment, the height of the anti-wheel removal wall 4 from the upper surface of the plate-like member 2 is about 13 mm, but is not limited to such a dimension. The wheel of the wheelchair in which the upper surface of the slope 1 is skewed in the direction of the outer end abuts against the anti-derailing wall 4 to prevent derailment from the slope 1.

  The derailment prevention wall 4 may be formed over the entire length of the outer edges of the plate-like members 2L and 2R. However, in this embodiment, as shown in FIGS. 1 and 2, the anti-roll-off wall 4 is not formed near at least one end in the longitudinal direction of the outer edge. This is because when the wheelchair gets into the slope 1 or gets off the slope 1, the traveling direction may be slightly inclined to the side. At the end of the slope 1, there is no major problem even if the wheelchair wheel comes off the side of the slope 1. On the other hand, it is often convenient that the wheelchair is slightly inclined and can get on and off the slope 1. The portion where the wheel removal preventing wall 4 is not formed is referred to as an oblique passage portion 5. In the present embodiment, the oblique passage portion 5 is provided on the rear end side (lower step side referred to as a step) of the plate-like members 2L and 2R. It may be provided only on the front end side, or may be provided on both front and rear end sides.

  In the present embodiment, the length of the plate-like members 2L and 2R is about 822 mm. It is 862 mm if the below-mentioned engagement plate 8 is included. The total width of the slope 1 when the three plate-like members 2 are opened is 862 mm. And the ratio range with respect to the full length of the plate-shaped members 2L and 2R of the length of the said skew passage part 5 is 20% or more and 30% or less. In the present embodiment, the length of the oblique passage portion 5 is 200 mm. The above dimensions are examples and are not limited to these.

  The plate-like members 2L and 2R at the left and right ends need to have a considerable strength because wheels such as wheelchairs are placed thereon. Since the plate-like members 2L and 2R are formed with the anti-wheel removal wall 4, the bending rigidity is greatly improved. As a result, the average thickness of the plate-like members 2L and 2R can be made thinner than that of the plate-like member on which the wheel removal preventing wall 4 is not formed. The average thickness of the plate-like members 2L and 2R in this embodiment is about 12 mm. The thickness of the conventional slope is about 20 mm. Thus, the slope 1 of the present embodiment can be made considerably thinner than the conventional slope. The slope 1 of this embodiment can be significantly reduced in weight. The slope 1 of this embodiment is finished to about 5.2 kg. However, it is not limited to the above-mentioned dimension of 12 mm and a weight of about 5.2 kg.

  As shown in FIGS. 1 and 2, an engagement plate 8 made of an aluminum alloy or the like is attached to one end in the longitudinal direction of the plate-like members 2 </ b> L and 2 </ b> R at both left and right ends along the edge. On the lower surface of the engagement plate 8, an engagement protrusion 9 is provided. A non-slip sheet 10 (not shown in FIG. 3) made of rubber or the like is attached to the other end portion of each plate-like member 2 in the longitudinal direction along the edge. When the slope 1 is stretched over a step, the engaging protrusion 9 is engaged with an upper stage such as a door rail of a railway vehicle, for example, and the anti-slip sheet 10 is pressed against a lower stage such as a platform of a station. In this way, the slope 1 can be installed on the step in a stable state.

  The engagement plate 8 is not attached to the central plate-like member 2C. As a result, a recess 6 is formed at the central portion of one end of the slope 1. The recess 6 is useful when the slope 1 is used for getting on and off a railway vehicle. This is because the recess 6 can avoid interference with the door stopper on the floor surface of the entrance / exit of the railway vehicle. Therefore, in the case of an application where there is no possibility of interference with the door stopper, the recess 6 does not need to be formed.

  As is apparent from FIG. 4 as well, a light-emitting device 7 is provided on each of the above-described wheel removal preventing walls 4. The light emitting device 7 includes a large number of light emitting diodes (LEDs) 11, a storage battery 12 as a power source for the LEDs 11, and an on / off switch 13 for the LEDs 11. In the present embodiment, 45 LEDs 11 are attached to one light emitting device 7. However, the number is not limited. The rated voltage of the 45 LEDs 11 is 7.2 V, the current consumption is about 238 mA, and the power consumption is about 2.16 W. Thus, the power-saving light-emitting device. However, it is not limited to the above specifications. The LED 11 is electrically connected to the storage battery 12 via the switch 13. The storage battery 12 has a connection terminal 14 for charging. As a light source of the light-emitting device 7, it is not limited to LED11, A small incandescent lamp, a fluorescent lamp, etc. may be used. Further, a reflector coated with a fluorescent paint may be used as necessary.

  In this embodiment, the LED 11 is housed in a rectangular parallelepiped case 15 that is partially or entirely formed of a transparent acrylic plate. The case 15 has a length slightly shorter than the derailment prevention wall 4 along the longitudinal direction of the derailment prevention wall 4. The case 15 is fixed to the outer surface of the derailment prevention wall 4 by rivets or the like. In the case 15, a large number of LEDs 11 are aligned along the longitudinal direction of the case 15. The case 15 has a rectangular cross section. The height of the case 15 is in the range of about 25 to 36 mm. The upper end of the case 15 is located slightly above the upper end of the anti-wheel removal wall 4. Since at least the outer surface and the upper surface of the case 15 are transparent, the light of the LED 11 is easily visually recognized from the side, upper, front, and rear directions. Of course, the front and rear ends and / or the inner surface of the case may also be made transparent.

  The case 15 is not limited to a box shape. For example, a plurality of LEDs 11 may be aligned along the longitudinal direction on a long plate-like member, and a transparent cover may be attached thereto. Further, a plurality of LEDs 11 may be aligned along the longitudinal direction on the outer surface and / or the upper end surface of the anti-derailing wall 4 and a transparent cover may be attached thereto.

  By operating the switch 13, the LED 11 can be turned on when the slope 1 is used and can be turned off when the slope 1 is not used. Charging the storage battery 12 is performed by connecting one plug of a charging adapter (not shown) to the connection terminal 14 of the storage battery 12 and the other plug to a power outlet (not shown). As a charging adapter, for example, DC7020 manufactured by Makita Corporation is inexpensive and easily available. The LED 11 can be lit for about 2.5 hours to about 3 hours by charging for about 3 hours. This charging adapter may be mounted in the case 15.

  The completed slope 1 is inspected for load resistance, deflection, durability, fixing performance, running surface anti-slip performance, and the like in accordance with JIS standard T9207 that defines "portable wheelchair slope", and satisfies the standards.

  By providing the derailment prevention wall 4, the bending rigidity of the plate-like members 2 </ b> L and 2 </ b> R at both the left and right ends is greatly improved. Thereby, the weight of the slope 1 can also be reduced. As a result, when the slope 1 is used at a railway station, it can be easily carried by female station staff.

  In the present embodiment, the light emitting device 7 is formed as a separate body from the anti-wheel removal wall 4, but is not limited to this configuration. For example, the derailment prevention wall may be formed separately from the plate-like members 2L and 2R, and the derailment prevention wall may have a light emitting function. In other words, the light-emitting device may have a function of preventing wheel loss. Specifically, one side plate (side plate on the plate-like member side) of the case 15 of the light emitting device 7 is formed from a strong material equivalent to the plate-like member 2, and this one side plate is formed by a rivet or the like into the plate-like member 2L, Fixed to 2R. According to this configuration, the one side plate can function as a derailment prevention wall.

  The portable slope according to the present invention can also be applied to a wheelchair communication passage between a railway vehicle entrance / exit and a station platform, a wheelchair passage on stairs, and the like.
