Description

本発明は段差や隙間のある場所などに掛け渡して車椅子等による走行を可能にする可搬式スロープに関する。    The present invention relates to a portable slope that can be traveled by a wheelchair or the like over a place with a step or a gap.

可搬式スロープは用途別に様々な仕様のものがあり、用途別に求められる顧客要望も異なるため、その都度、必要強度などに応じて形状や使用材料を決定し、且つ設計する必要があり部材を共通化できないという一面を有している。
そのため、スロープ毎に様々な仕様の専用部材を準備しなければならず生産性が悪いという問題点がある。
例えば、下記の特許文献１には、建物や、電車等の物体間に生じる段差に掛け渡して使用する携帯用スロープに関し、軽量、且つ耐荷重性、耐久性に優れ、またスロ−プの両側面に脱輪防止壁を設置することで車いす利用者がスロープ上を安全に搬送でき、またスロープ自体が軽量のため、その運搬性にも優れているとされる携帯用スロープが開示されている。 There are various types of portable slopes depending on the application, and customer requirements required for each application are different, so it is necessary to determine the shape and materials used according to the required strength and design each time, and common parts are common. It has one aspect that cannot be made.
Therefore, there is a problem in that productivity is poor because special members having various specifications must be prepared for each slope.
For example, Patent Document 1 below relates to a portable slope that is used across a step formed between objects such as buildings and trains, and is lightweight, excellent in load resistance and durability, and on both sides of the slope. A wheelchair user can safely transport on the slope by installing an anti-derailing wall on the surface, and since the slope itself is lightweight, a portable slope that is said to be excellent in its transportability is disclosed .

この特許文献１に示された携帯用スロープは、少なくとも板材及び第１の補強部とからなり、前記第１の補強部はスロープの長手方向に延設され、前記板材と前記第１の補強部の間に中空部が形成された構造となっており、また、板材の側端面及び第１の補強部の側端面の少なくとも一部と合致接合するように脱輪防止壁が配置された携帯用スロープとなっている。    The portable slope shown in Patent Document 1 includes at least a plate material and a first reinforcing portion, and the first reinforcing portion extends in the longitudinal direction of the slope, and the plate material and the first reinforcing portion are provided. The portable device has a structure in which a hollow portion is formed between them, and a derailment prevention wall is disposed so as to coincide with and join at least part of the side end surface of the plate member and the side end surface of the first reinforcing portion. It is a slope.

特開２０１６−６７５１７号公報Japanese Patent Laid-Open No. 2006-67517

特許文献１に示された携帯用スロープにおいては、脱輪防止壁と合致する第１の補強部の底角θの一つは略９０度であり、底角θの一つが略９０度となる側面は板材側端面と同一面方向に位置することで、脱輪防止壁は板材側端面と補強部の垂直な面と同一面上に合致することができ、そのため、脱輪防止壁が板材側端面と第１の補強部側面部と合致接合させることにより、脱輪防止壁が板材及び第１の補強部の両方と接合することにより、脱輪防止壁の変形や破断に対して耐衝撃性が強固になるとされている。    In the portable slope shown in Patent Document 1, one of the base angles θ of the first reinforcing portion that coincides with the anti-roll-off wall is approximately 90 degrees, and one of the base angles θ is approximately 90 degrees. Since the side surface is positioned in the same plane direction as the plate-side end surface, the anti-derailing wall can be flush with the plate-side end surface and the vertical surface of the reinforcing part. By joining the end face and the first reinforcing part side-to-face, the anti-derailing wall joins both the plate material and the first reinforcing part, and thus is resistant to deformation and breakage of the anti-derailing wall. Is supposed to be strong.

また、特許文献１に示された携帯用スロープにおいては、さらに第２の補強部が配置されることが好ましいものとされ、当該第２の補強部が板材と第１の補強部の間に形成された中空部に挿入可能に構成されることが好ましいとされている。    Moreover, in the portable slope shown in Patent Document 1, it is preferable that a second reinforcing portion is further disposed, and the second reinforcing portion is formed between the plate material and the first reinforcing portion. It is preferable to be configured so that it can be inserted into the hollow portion.

このように、特許文献１に示された携帯用スロープにあっては、顧客から求められる耐荷重強度などに応じて、第１の補強部の底角θの角度を変更したり、第１の補強部の他に第２の補強部を配置したりしなければならず、使用部材を共通化することができないため、生産性が悪く経済的に不利になるという問題点がある。    Thus, in the portable slope shown in Patent Document 1, the angle of the bottom angle θ of the first reinforcing portion is changed according to the load-bearing strength required by the customer, In addition to the reinforcing portion, the second reinforcing portion must be arranged, and the members to be used cannot be made common, so that there is a problem in that productivity is poor and economically disadvantageous.

本発明は、前記した従来の可搬式スロープにおける諸問題点を解消し、側縁部に予めエッジプロテクターとしての枠部材が取付けられているスロープ板を基本部材とし、当該スロープ板の長手方向左右両側縁部に沿って、当該左右両側縁部形状に対応した凹部を形成してなる複数種類の補強チャンネルを作製し、これら複数種類の補強チャンネルを使用環境に応じて選択的に取付けてスロープ全体の強度等を向上するようにした選択可能な補強部材を具備してなる可搬式スロープを提供することを目的とするものである。    The present invention eliminates various problems in the above-described conventional portable slope, and uses a slope plate in which a frame member as an edge protector is attached in advance to a side edge as a basic member, and both left and right sides in the longitudinal direction of the slope plate. A plurality of types of reinforcement channels formed by forming recesses corresponding to the left and right side edge shape along the edge, and selectively mounting these plurality of types of reinforcement channels according to the use environment It is an object of the present invention to provide a portable slope including a selectable reinforcing member that improves strength and the like.

芯材２を構成する発泡性合成樹脂としては、ポリスチレン、ポリプロピレン、硬質ポリウレタン、ＰＶＣ、アクリル樹脂等が好適に用いられる。
なお、基本部材としては、前記した芯材２の表裏両面に板材３，３を接着して一体化を図ると共に、左右両側縁部に枠部材９，９を嵌着して構成したものが好適に用いられるが、これ以外にも、繊維強化プラスチック（ＦＲＰ）あるいは炭素繊維強化プラスチック（ＣＦＲＰ）を用いて一体成形したものを基本部材として用いることができるのは勿論である。 In the figure, reference numerals 1, 1A, 1B, and 1C denote slope plates serving as basic members constituting the portable slope according to the present invention. The slope plates 1, 1A, 1B, and 1C are bonded to light and strong plate materials 3 and 3 on both front and back surfaces of a core material 2 having a required thickness made of synthetic resin foam, for example. In addition, the frame member 9 made of an aluminum alloy or the like is fitted to the left and right side edges along the direction of travel.
As the foamable synthetic resin constituting the core material 2, polystyrene, polypropylene, hard polyurethane, PVC, acrylic resin, or the like is preferably used.
In addition, as a basic member, what comprised the board | plate materials 3 and 3 on both front and back both surfaces of the above-mentioned core material 2 and aiming at integration, and the frame members 9 and 9 were fitted to the both right and left edge parts, and was comprised suitably In addition to this, it is of course possible to use, as a basic member, a material integrally molded using fiber reinforced plastic (FRP) or carbon fiber reinforced plastic (CFRP).

図１は矩形状をなす３枚のスロープ板１Ａ，１Ｂ，１Ｃを、車椅子等の走行方向に合わせて並列させ、連結部材４を介して互いに折りたたみができるように連結した構成となっているが、１枚のスロープ板の幅方向寸法を大きくして、２枚のスロープ板１Ａ，１Ｂを連結する構成としてもよく、さらにはきわめて広幅状とした１枚のみからなるスロープ板１であっても、本発明が対象とする可搬式スロープとすることができる。    FIG. 1 shows a configuration in which three slope plates 1A, 1B, 1C having a rectangular shape are arranged in parallel according to the traveling direction of a wheelchair or the like and are connected to each other via a connecting member 4 so that they can be folded together. The width dimension of one slope plate may be increased to connect the two slope plates 1A and 1B, and even the slope plate 1 consisting of only one sheet having a very wide shape. It can be set as the portable slope which this invention makes object.

前記連結部材４は、図示の実施形態においては、繰り返し使用に耐えることができる強度を有する織布、不織布、ゴムシート、エラストマー製シ−ト等からなる帯状片を用いており、当該連結用帯状片をスロープ板同士の突き合わせ部を跨ぐようにして接着等の手段でスロープ板に取付けるようにしてある。
連結部材４としての連結用帯状片は、図１においてスロープ単体１Ａとスロープ単体１Ｂの突き合わせ部のみに示してあるが、スロープ単体１Ｂとスロープ単体１Ｃの突き合わせ部には裏側において連結用帯状片を付設してある。このように交互に連結用帯状片を適用することによって各スロープ単体１Ａ，１Ｂ，１Ｃの折りたたんだ状態が嵩高となるのを防ぐことができる。
なお、連結部材４は前記した帯状片以外にも、蝶番等に置き換えることができるのは勿論であり、当該連結部材の変更が本発明の範囲に影響を与えるものではない。 In the illustrated embodiment, the connecting member 4 uses a strip-shaped piece made of a woven fabric, a nonwoven fabric, a rubber sheet, an elastomer sheet, or the like having a strength that can withstand repeated use. The piece is attached to the slope plate by means such as adhesion so as to straddle the butted portion of the slope plates.
The connecting strip 4 as the connecting member 4 is shown only in the abutting portion of the slope unit 1A and the slope unit 1B in FIG. It is attached. By alternately applying the connecting strips in this way, it is possible to prevent the folded state of each of the slope single bodies 1A, 1B, 1C from becoming bulky.
Of course, the connecting member 4 can be replaced with a hinge or the like other than the above-described belt-like piece, and the change of the connecting member does not affect the scope of the present invention.

また、図１に示すスロープ板１Ａ，１Ｂ，１Ｃの長手方向一端面には車椅子等による走行を円滑に行なうための先端部材５，５が取付けられていると共に、スロープ単体１Ａ，１Ｂ，１Ｃの長手方向他端面には下端部材６が取付けられている。なお、前記先端部材５，５の裏側には、図示しないが係止片が設けられていて、当該係止片を例えば電車のドアレールの内側に係合させて、スロープ全体が車椅子等の走行中にずれるのを防ぐことができるようになっている。    Further, tip members 5 and 5 for smoothly running with a wheelchair or the like are attached to one longitudinal end surface of the slope plates 1A, 1B and 1C shown in FIG. A lower end member 6 is attached to the other end surface in the longitudinal direction. Although not shown, a locking piece is provided on the back side of the tip members 5 and 5, and the locking piece is engaged with, for example, the inner side of a door rail of a train so that the entire slope is running such as a wheelchair. It can be prevented from shifting.

本発明は、前記した可搬式スロープにおいて、基本部材となるスロープ板１，１Ａ，１Ｂ，１Ｃの左右両側縁部に沿って、当該左右両側縁部形状に対応した凹部７を形成してなる複数種類の補強チャンネル８を作製準備しておき、これら複数の補強チャンネル８の中から使用条件に適ったものを選択して、枠部材９が嵌着されているスロープ板の側縁部に沿って取付けて当該スロープ全体の強度を高めるように構成したものである。    The present invention includes a plurality of concave portions 7 corresponding to the shape of the left and right side edges along the left and right side edges of the slope plates 1, 1 </ b> A, 1 </ b> B, and 1 </ b> C serving as a basic member. A type of reinforcing channel 8 is prepared and prepared, and one of the plurality of reinforcing channels 8 is selected according to the use conditions, and along the side edge of the slope plate on which the frame member 9 is fitted. It attaches and is comprised so that the intensity | strength of the said whole slope may be raised.

なお、図１に示すように、複数枚のスロープ板１Ａ，１Ｂ，１Ｃを並列させ、連結部材４を介して互いに折りたたみ可能なように連結して構成したスロープの場合は、当該スロープ全体の外側となる左右両側縁部、すなわちスロープ板１Ａの左側縁部と、スロープ板１Ｃの右側縁部に沿って、当該左右両側縁部形状に対応した凹部７を形成してなる補強チャンネル８を選択的に取付けてスロープ全体の強度を高めるようにすることができる。    As shown in FIG. 1, in the case of a slope constructed by connecting a plurality of slope plates 1A, 1B, 1C in parallel so as to be foldable with each other via a connecting member 4, the outside of the entire slope. The reinforcement channel 8 formed by forming the recesses 7 corresponding to the left and right side edge portions along the right and left side edges, that is, the left side edge of the slope plate 1A and the right side edge of the slope plate 1C is selectively selected. To increase the strength of the entire slope.

すなわち、この実施形態の場合は、スロープ板１Ａとスロープ板１Ｂ、スロープ板１Ｂとスロープ板１Ｃがそれぞれ互いに向き合う側縁部には補強チャンネル８を取付けず、スロープ板１Ａとスロープ板１Ｃのそれぞれの自由端となる側縁部のみに補強チャンネル８，８を取付けるようにしたものである。    That is, in the case of this embodiment, the reinforcing channel 8 is not attached to the side edges where the slope plate 1A and the slope plate 1B, and the slope plate 1B and the slope plate 1C face each other, and each of the slope plate 1A and the slope plate 1C. Reinforcing channels 8 and 8 are attached only to the side edges that are free ends.

なお、スロープ本体の上面で車椅子走行による荷重を受けた際に生じるスロープ本体の撓みをより良く抑制するためには、特に図示しないが、スロープ板１Ａとスロープ板１Ｂ、スロープ板１Ｂとスロープ板１Ｃがそれぞれ互いに向き合う側縁部にも通常のコ字型をなす補強チャンネル８を取付けるようにしてもよいのは勿論であり、当該箇所にも補強チャンネル８を取付けることによりスロープ全体の耐荷重性が飛躍的に向上する。    Although not particularly shown, the slope plate 1A and the slope plate 1B, and the slope plate 1B and the slope plate 1C are not particularly shown in order to better suppress the bending of the slope body that occurs when a load due to wheelchair travel is received on the upper surface of the slope body. Of course, reinforcing channels 8 having a normal U-shape may be attached to the side edges facing each other, and the load resistance of the entire slope can be improved by attaching the reinforcing channels 8 to the corresponding portions. Improve dramatically.

補強チャンネル８はスロープ板１，１Ａ，１Ｂ，１Ｃの長手方向長さと同程度かまたは若干短めの長手方向寸法を有し、スロープ板の左右両側縁部に密嵌できる凹部７を形成してある。なお、図８に示すように、基本部材となるスロープ板１の側縁部にはエッジプロテクターとしてのアルミ合金等からなる枠部材９が取付けられており、当該枠部材９を含むスロープ板１の左右両側縁部形状に対応した凹部７、すなわちスロープ板１の当該左右両側縁部形状全体を抱持し得る凹部７を補強チャンネル８に形成しておく必要があるのは勿論である。    The reinforcing channel 8 has a longitudinal dimension that is approximately the same as or slightly shorter than the longitudinal length of the slope plates 1, 1 </ b> A, 1 </ b> B, 1 </ b> C, and is formed with recesses 7 that can be tightly fitted to the left and right edges of the slope plate. . As shown in FIG. 8, a frame member 9 made of an aluminum alloy or the like as an edge protector is attached to the side edge of the slope plate 1 as a basic member, and the slope plate 1 including the frame member 9 is attached. Of course, it is necessary to form the recess 7 corresponding to the left and right side edge shape, that is, the recess 7 capable of holding the entire left and right side edge shape of the slope plate 1 in the reinforcing channel 8.

補強チャンネル８はスロープ板１，１Ａ，１Ｂ，１Ｃを構成する合板等の走行方向に対する外側面に密嵌されることにより、当該合板側端面に諸種の物体が接触し、合板側端面が損傷するのを防ぎ、且つ各スロープ板１，１Ａ，１Ｂ，１Ｃを構成する芯材２及び当該芯材２の表裏両面に位置しているＦＲＰ等の板材３，３の板厚方向への接合を枠部材９と協働的に補助することで、これらの剥離を防ぐと共に、スロープ本体の上面で車椅子走行等による荷重を受けた際に生じるスロープ板の撓みを抑制することができ、スロープ全体の耐久性向上に寄与する。    The reinforcing channel 8 is closely fitted to the outer surface of the slope plates 1, 1A, 1B, and 1C in the running direction of the plywood, etc., so that various objects come into contact with the plywood side end surface and the plywood side end surface is damaged. And the joining of the core material 2 constituting each slope plate 1, 1 </ b> A, 1 </ b> B, 1 </ b> C and the plate materials 3, 3 such as FRP located on both front and back surfaces of the core material 2 in the thickness direction. By assisting in cooperation with the member 9, these peelings can be prevented, and bending of the slope plate that occurs when a load due to wheelchair running or the like is received on the upper surface of the slope body can be suppressed. Contributes to improved performance.

なお、補強チャンネル８の材質としては、アルミ合金、鋼板、ステンレス、チタン合金等の金属系が好適に用いられるが、ポリプロピレン、ポリカーボネート、ポリアミド、ＦＲＰ、ＣＦＲＰ等の樹脂系、またはこれらを組み合わせたものが適用可能であり、耐荷重強度や顧客要望等に応じ使用素材を適宜決定する。

その他、例えば通常のコ字型チャンネル８の外周部に緩衝用の弾性部材からなる被覆体を嵌め付けて、スロープに側面から衝撃が加わったときに当該衝撃を和らげ車椅子利用者に対する安全性を高めるようにすることも可能である。その際、コ字型チャンネル８の外周部形状に前記被覆体を係止することができる図示しない係合部を形成しておく。 In addition, the U-shaped channel (reinforcing channel 8) with guide pieces in which the guide piece 10 for preventing the wheel removal is formed, in addition to the standard reinforcing channel 8 manufactured using a normal plate thickness material as shown in FIG. As shown in FIG. 6, it is possible to immediately cope with the required strength by preparing the reinforcing channel 8 having an improved load bearing strength using a thick material.
In addition, for example, a cover made of an elastic member for buffering is fitted on the outer periphery of a normal U-shaped channel 8, and when the impact is applied to the slope from the side, the impact is reduced and the safety for the wheelchair user is improved. It is also possible to do so. At this time, an engagement portion (not shown) that can lock the covering body on the outer peripheral shape of the U-shaped channel 8 is formed.

さらに、極微小なガラスビーズを合成樹脂層に均一に定着させて構成した再帰反射シートを交換可能な補強チャンネル８の外周面に貼着することによってスロープ使用現場の視認性ないし機能性を高めるようにしたり、あるいは蓄光塗料を補強チャンネル８の外周面に塗布して前記と同様の効果を奏するようにすることもでき、これらの部材を付設した補強チャンネル８も選択肢の一つとなり得るものである。    Further, by attaching a retroreflective sheet composed of extremely fine glass beads uniformly fixed on the synthetic resin layer to the outer peripheral surface of the replaceable reinforcing channel 8, the visibility or functionality at the site of use of the slope is enhanced. Alternatively, a phosphorescent paint can be applied to the outer peripheral surface of the reinforcing channel 8 to achieve the same effect as described above, and the reinforcing channel 8 provided with these members can be one of the options. .

補強チャンネル８をスロープ板１，１Ａ，１Ｂ，１Ｃの側縁部に取付けるにあたっては、例えば補強チャンネル８に形成してある凹部７内に接着剤を均一に塗布してから、スロープ板１，１Ａ，１Ｂ，１Ｃの側縁部を凹部７内に圧入し固定するようにしてもよいし、ビス止めによって固定するようにしてもよい。あるいは接着剤とビス止めを併用することもできる。なお、前記した先端部材５や下端部材６は、スロープ板１，１Ａ，１Ｂ，１Ｃの側縁部に補強チャンネル８を取付けてから順次スロープ単体の長手方向両端面部に取付ける。    In attaching the reinforcing channel 8 to the side edges of the slope plates 1, 1 </ b> A, 1 </ b> B, 1 </ b> C, for example, an adhesive is uniformly applied in the recess 7 formed in the reinforcing channel 8 and then the slope plates 1, 1 </ b> A. , 1B, 1C may be press-fitted into the recess 7 and fixed, or may be fixed by screwing. Alternatively, an adhesive and a screw stopper can be used in combination.
