Description

車両のスロープ装置Slope device for vehicle
　本発明は、車椅子を押しながら車両に載せる際に使用されるスロープ装置に関する。 The present invention relates to a slope device used when placing on a vehicle while pushing a wheelchair.
　特開平１１－１１３９６１号公報に記載されているスロープ装置は、自動車の車体後部の開口部に設置される装置であり、スロープ板を後方に展開させて開口部と地面に架け渡すことで、車椅子を押しながら車室内に入れることができるように構成されている。車椅子を車室内に載せた後、このスロープ板を上方に回動させて車室内に格納する。具体的には、スロープ板は上方に回動する過程で中央部分が山形に折れ曲がり、さらに回動して２つに折り畳まれた状態で車室のフロア上に格納される。このようにスロープ板が車室のフロア上に格納されるため、車椅子はスロープ板の格納位置より前側で車室のフロアに固定する必要がある。 The slope device described in Japanese Patent Laid-Open No. 11-113961 is a device that is installed in an opening at the rear of the body of an automobile, and a wheelchair is developed by extending the slope plate rearward and spanning the opening and the ground. It is configured to be able to enter the passenger compartment while pressing. After the wheelchair is placed in the vehicle interior, the slope plate is rotated upward and stored in the vehicle interior. Specifically, the slope plate is stored on the floor of the passenger compartment in a state where the central portion is bent into a mountain shape in the process of rotating upward, and further rotated and folded into two. Thus, since the slope board is stored on the floor of the passenger compartment, the wheelchair needs to be fixed to the floor of the passenger compartment in front of the storage position of the slope board.
　上記スロープ装置のようにスロープ板を車室のフロア上に格納すると、車室の最後部には車椅子を固定することができない。このため、例えば２台の車椅子を車室の後部に前後に並べて載せるようなことが不可能である。したがって、車室内空間の有効利用が図れないという問題がある。 If the slope plate is stored on the floor of the passenger compartment as in the case of the above-mentioned slope device, the wheelchair cannot be fixed to the rearmost part of the passenger compartment. For this reason, for example, it is impossible to place two wheelchairs side by side in the rear part of the passenger compartment. Therefore, there is a problem that the vehicle interior space cannot be effectively used.
　この点を改善するには、スロープ板を開口部の近傍に起立状態で格納するように構成することもできる。これにより、車室の最後部にも車椅子を載せることが可能になる。しかし、車椅子の代わりに、開口部を通して車室に荷物を積みたい場合、スロープ板が開口部の近傍に起立していると邪魔になる。このため、荷物の積み降ろしをするには、ドアを開けた後、スロープ板を一旦外方に展開する必要があり、作業が面倒になるという問題がある。 In order to improve this point, the slope plate can be stored in an upright position near the opening. Thereby, it becomes possible to place a wheelchair on the rearmost part of the passenger compartment. However, instead of a wheelchair, when it is desired to load a luggage in the passenger compartment through the opening, it becomes an obstacle if the slope plate stands in the vicinity of the opening. For this reason, in order to load and unload a load, it is necessary to once unfold the slope plate after opening the door, and there is a problem that the work becomes troublesome.
　本発明の一つの観点によると、車両のスロープ装置は、車室に通じる車体の開口部の下辺に回動可能に連結され前記開口部の下辺と地面との間に掛け渡すことのできるスロープ板と、上方に回動した前記スロープ板を起立位置に保持し前記車室内に格納するための主ロック機構と、を備えている。また、前記スロープ板は、前記起立位置から前記車室の内方に倒伏させることができるように構成されている。 According to one aspect of the present invention, a slope device for a vehicle is connected to a lower side of an opening of a vehicle body that leads to a passenger compartment so as to be rotatable and can be spanned between the lower side of the opening and the ground. And a main lock mechanism for holding the slope plate rotated upward in an upright position and storing it in the vehicle interior. Further, the slope plate is configured to be able to fall from the standing position to the inside of the passenger compartment.
　この構成によれば、スロープ板は起立位置から車室内方に倒伏可能に構成されている。このため、例えば、車両に車椅子を載せない場合には、スロープ板を起立位置から車室内方に倒伏させることで、開口部から荷物を積むことが可能になる。したがって、スロープ板が荷物の積み降ろしの邪魔になることがない。即ち、荷物の積み降ろしを行う毎にスロープ板を展開させる必要がなくなり、荷物の積み降ろし作業が容易になる。 According to this configuration, the slope plate is configured to be able to fall from the standing position toward the vehicle interior. For this reason, for example, when the wheelchair is not placed on the vehicle, it is possible to load the luggage from the opening by causing the slope plate to fall from the standing position toward the vehicle interior. Therefore, the slope plate does not obstruct the loading / unloading of luggage. In other words, it is not necessary to unfold the slope plate every time the load is loaded / unloaded, and the load / unload operation is facilitated.

　支持架台３０の左右のアーム状側板部３２には、ロック解除ボックス６０ｂが取付けられている。ロック解除ボックス６０ｂは、部分ロック機構５０のストライカ係合部５５の上側に配置されている。図１１Ａに示すように、主ロック解除レバー４７と部分ロック解除レバー５７は、アーム状側板部３２の表面に沿って回動可能に、このロック解除ボックス６０ｂに取付けられている。主ロック解除レバー４７と部分ロック解除レバー５７は、原位置では図１１Ａに示すようにロック解除ボックス６０ｂから外へ上方に延びている。 The lock release box 60b is attached to the left and right arm-shaped side plates 32 of the support frame 30. The unlocking box 60 b is disposed on the upper side of the striker engaging portion 55 of the partial lock mechanism 50. As shown in FIG. 11A, the main lock release lever 47 and the partial lock release lever 57 are attached to the lock release box 60b so as to be rotatable along the surface of the arm-shaped side plate portion 32. The main lock release lever 47 and the partial lock release lever 57 extend upward from the lock release box 60b in the original position as shown in FIG. 11A.
　主ロック解除レバー４７は、原位置から後方（図９では右）に回動できるが、前方（左）には回動できないように構成されている。主ロック解除レバー４７は、後方に回動させる操作をすることで、主ロック機構４０のロック状態を解除することができるように構成されている。 The main lock release lever 47 can be rotated backward (right in FIG. 9) from the original position, but cannot be rotated forward (left). The main lock release lever 47 is configured to be able to release the locked state of the main lock mechanism 40 by performing an operation of rotating backward.
　部分ロック解除レバー５７は、原位置から前方（図９では左）に回動できるが、後方（右）には回動できないように構成されている。部分ロック解除レバー５７は、前方に回動させる操作をすることで、部分ロック機構５０のロック状態を解除することができるように構成されている。 The partial lock release lever 57 can be rotated forward (left in FIG. 9) from the original position, but cannot be rotated backward (right). The partial lock release lever 57 is configured to be able to release the locked state of the partial lock mechanism 50 by performing an operation of rotating forward.
＜インターロック装置＞
　ロック解除機構６０は、主ロック機構４０のロック状態と部分ロック機構５０のロック状態とが同時に解除されることを防止するインターロック装置を備えている。インターロック装置は、主ロック解除レバー４７および部分ロック解除レバー５７の回動を規制するためのアクチュエータである第１ソレノイド６４と第２ソレノイド６５を有している。第１ソレノイド６４と第２ソレノイド６５は、図１１Ａに示すようにロック解除ボックス６０ｂに設けられている。 <Interlock device>
The lock release mechanism 60 includes an interlock device that prevents the lock state of the main lock mechanism 40 and the lock state of the partial lock mechanism 50 from being released simultaneously. The interlock device includes a first solenoid 64 and a second solenoid 65 that are actuators for restricting the rotation of the main lock release lever 47 and the partial lock release lever 57. The first solenoid 64 and the second solenoid 65 are provided in the unlocking box 60b as shown in FIG. 11A.
　第１ソレノイド６４は、作動時には図１１Ｂに鎖線で示すようにプランジャを押し出して原位置にある主ロック解除レバー４７の後方への回動を禁止し、非作動時には実線で示すようにプランジャを引き込んで主ロック解除レバー４７の後方への回動を許容する。第２ソレノイド６５は、作動時には図１１Ｂに鎖線で示すようにプランジャを押し出して原位置にある部分ロック解除レバー５７の前方への回動を禁止し、非作動時には実線で示すようにプランジャを引き込んで部分ロック解除レバー５７の前方への回動を許容する。 When actuated, the first solenoid 64 pushes out the plunger as shown by a chain line in FIG. 11B to inhibit the main lock release lever 47 in the original position from rotating backward, and when not actuated, pulls the plunger as shown by a solid line. Thus, the main lock release lever 47 is allowed to rotate backward. When actuated, the second solenoid 65 pushes out the plunger as shown by a chain line in FIG. 11B to prohibit the partial lock release lever 57 in the original position from rotating forward, and retracts the plunger as shown by a solid line when not actuated. Thus, the partial lock release lever 57 is allowed to rotate forward.
　インターロック装置はまた、第１ソレノイド６４と第２ソレノイド６５を作動させるための第１スイッチ６１及び第２スイッチ６２を備えている。 The interlock device also includes a first switch 61 and a second switch 62 for operating the first solenoid 64 and the second solenoid 65.
　第１スイッチ６１は、図１０に示すように主ロック機構４０のストライカ係合部４５に設けられている。第１スイッチ６１は、ストライカ係合部４５のフックが車体側のストライカ４３に係合する動作によってオフとなり、係合が解ける動作によってオンとなるように構成されている。第１スイッチは配線にて第２ソレノイドと電気的に接続されており、第１スイッチがオンとなると第２ソレノイドが作動する。 The first switch 61 is provided in the striker engaging portion 45 of the main lock mechanism 40 as shown in FIG. The first switch 61 is configured to be turned off when the hook of the striker engaging portion 45 is engaged with the striker 43 on the vehicle body side and turned on when the engagement is released. The first switch is electrically connected to the second solenoid through wiring, and the second solenoid is activated when the first switch is turned on.
　また、第２スイッチ６２は、部分ロック機構５０のストライカ係合部５５に設けられている。第２スイッチ６２は、ストライカ係合部５５のフックがスロープ板本体のストライカ５３に掛けられる動作によってオフとなり、係合が解ける動作によってオンとなるように構成されている。第２スイッチは配線にて第１ソレノイドと電気的に接続されており、第２スイッチがオンとなると第１ソレノイドが作動する。 Further, the second switch 62 is provided in the striker engaging portion 55 of the partial lock mechanism 50. The second switch 62 is configured to be turned off when the hook of the striker engaging portion 55 is hooked on the striker 53 of the slope plate body, and turned on when the engagement is released. The second switch is electrically connected to the first solenoid by wiring, and the first solenoid is activated when the second switch is turned on.
　スロープ板本体と支持架台とが共に起立位置に保持されている時には、ボディ側のストライカ４３とスロープ板本体側のストライカ５３の両方がそれぞれ係合している。したがって、第１スイッチ６１と第２スイッチ６２が共にオフであり、図１１Ｂに示すように第１ソレノイド６４と第２ソレノイド６５は共に非作動状態である。これにより、原位置にある主ロック解除レバー４７の後方への回動、原位置にある部分ロック解除レバー５７の前方への回動が、共に許容されている。したがって、主ロック解除レバー４７を操作して主ロック機構４０のロック状態を解除したり、あるいは部分ロック解除レバー５７を操作して部分ロック機構５０のロック状態を解除することができる。 When the slope plate body and the support frame are both held in the standing position, both the striker 43 on the body side and the striker 53 on the slope plate body side are engaged with each other. Therefore, both the first switch 61 and the second switch 62 are off, and both the first solenoid 64 and the second solenoid 65 are inactive as shown in FIG. 11B. Thereby, both the rearward rotation of the main lock release lever 47 in the original position and the forward rotation of the partial lock release lever 57 in the original position are permitted. Therefore, the main lock release lever 47 can be operated to release the lock state of the main lock mechanism 40, or the partial lock release lever 57 can be operated to release the lock state of the partial lock mechanism 50.
　主ロック解除レバー４７を操作して主ロック機構４０のロック状態を解除し、スロープ板本体を支持架台とともに後方に倒すと、ボディ側のストライカ４３の係合が解ける。これにより、第１スイッチ６１がオンとなり、ロック解除ボックス６０ｂにおいて第２ソレノイド６５のみが図１１Ｂにおいて鎖線で示すように作動して、部分ロック解除レバー５７の前方への回動が禁止される。 When the main lock release lever 47 is operated to release the lock state of the main lock mechanism 40 and the slope plate body is tilted backward together with the support frame, the striker 43 on the body side is disengaged. As a result, the first switch 61 is turned on, and only the second solenoid 65 operates in the lock release box 60b as shown by the chain line in FIG. 11B, and the partial lock release lever 57 is prohibited from rotating forward.
　また、部分ロック解除レバー５７を操作して部分ロック機構５０のロック状態を解除し、スロープ板本体を前方に倒すと、スロープ板本体側のストライカ５３の係合が解ける。これにより、第２スイッチ６２がオンとなり、ロック解除ボックス６０ｂにおいて第１ソレノイド６４のみが図１１Ｂにおいて鎖線で示すように作動して、主ロック解除レバー４７の後方への回動が禁止される。 Further, when the partial lock release lever 57 is operated to release the lock state of the partial lock mechanism 50 and the slope plate body is tilted forward, the striker 53 on the slope plate body side is disengaged. As a result, the second switch 62 is turned on, and only the first solenoid 64 operates in the unlock box 60b as shown by the chain line in FIG. 11B, and the main lock release lever 47 is prohibited from rotating backward.
＜スロープ装置の動作＞
　スロープ装置１０が車両に格納されている状態では、スロープ板本体２０と支持架台３０は図３、図４に示すように共に起立位置にあって、主ロック機構４０と部分ロック機構５０とがロック状態に保持されている。このとき、主ロック機構４０の第１スイッチ６１と部分ロック機構５０の第２スイッチ６２が共にオフであり、第１ソレノイド６４と第２ソレノイド６５とが図１１Ｂに実線で示すように共に非作動状態である。これにより、原位置にある主ロック解除レバー４７、あるいは原位置にある部分ロック解除レバー５７の回動操作が可能になる。 <Operation of the slope device>
In the state in which the slope device 10 is stored in the vehicle, the slope plate body 20 and the support frame 30 are both in the upright position as shown in FIGS. 3 and 4, and the main lock mechanism 40 and the partial lock mechanism 50 are locked. Held in a state. At this time, both the first switch 61 of the main lock mechanism 40 and the second switch 62 of the partial lock mechanism 50 are off, and the first solenoid 64 and the second solenoid 65 are not operated as shown by a solid line in FIG. 11B. State. As a result, the main lock release lever 47 at the original position or the partial lock release lever 57 at the original position can be rotated.
　車椅子を車室に乗せるには、ドアＤを開き、必要に応じて車両の後部を所定位置まで下降させた後、まず左右の主ロック解除レバー４７を操作して主ロック機構４０のロック状態を解除する。次に、支持架台３０と一体に保持されているスロープ板本体２０を後方に（右回りに）回動させて、図９に示すように車体Ｃの開口部Ｈと地面との間に掛け渡す。このとき、必要に応じてスロープ板本体２０の第２板部２２から第１板部２１を引き出す。この架け渡されたスロープ板本体２０の上を、車椅子を押しながら開口部Ｈを通して車室に乗せることが可能になる。 To place the wheelchair in the passenger compartment, after opening the door D and lowering the rear part of the vehicle to a predetermined position as necessary, first, the left and right main lock release levers 47 are operated to change the lock state of the main lock mechanism 40. To release. Next, the slope plate main body 20 held integrally with the support frame 30 is rotated backward (clockwise) and passed between the opening H of the vehicle body C and the ground as shown in FIG. . At this time, the 1st board part 21 is pulled out from the 2nd board part 22 of the slope board main body 20 as needed. It is possible to place the bridge on the slope plate main body 20 through the opening H while pushing the wheelchair.
　ここで、スロープ板本体２０が後方に倒れた状態では主ロック機構４０の第１スイッチ６１がオンになっているため、第２ソレノイド６５が作動して部分ロック解除レバー５７による解除操作が禁止されている。これにより、例えば誤って部分ロック解除レバー５７に触れても、部分ロック機構５０のロック状態が解除されることがない。したがって、スロープ板本体２０を後方に倒す際または使用する際に、スロープ板本体２０と支持架台３０との連結部分が（スロープ板本体２０の回動中心Ｃ２で）折れ曲がる危険が生じない。 Here, since the first switch 61 of the main lock mechanism 40 is turned on when the slope plate body 20 is tilted rearward, the second solenoid 65 is activated and the release operation by the partial lock release lever 57 is prohibited. ing. Thereby, even if the partial lock release lever 57 is accidentally touched, the locked state of the partial lock mechanism 50 is not released. Therefore, when the slope plate body 20 is tilted backward or used, there is no risk that the connecting portion between the slope plate body 20 and the support base 30 is bent (at the rotation center C2 of the slope plate body 20).
　車椅子を車室内に乗せた後は、スロープ板本体２０の第１板部２１を第２板部２２に重ねて収納し、支持架台３０と一体に保持されているスロープ板本体２０を上方に（左回りに）回動させる。そして、スロープ板本体２０と支持架台３０とが図４に示す起立位置まで到達した時点で、左右の各側でボディパネル４のストライカ４３が支持架台３０のストライカ係合部４５と係合し、主ロック機構４０がロック状態となる。これにより、スロープ板本体２０と支持架台３０とが起立位置に保持される。 After the wheelchair is placed in the passenger compartment, the first plate portion 21 of the slope plate main body 20 is stored on the second plate portion 22 so that the slope plate main body 20 held integrally with the support frame 30 is moved upward ( Rotate counterclockwise. Then, when the slope plate body 20 and the support frame 30 reach the standing position shown in FIG. 4, the striker 43 of the body panel 4 is engaged with the striker engagement portion 45 of the support frame 30 on each of the left and right sides, The main lock mechanism 40 is locked. Thereby, the slope board main body 20 and the support stand 30 are hold | maintained in an upright position.
　また、車体Ｃ後部の開口部Ｈを通して車室に荷物を積むには、スロープ板本体２０が図１に示すように起立位置にあると邪魔になる。そこで、ドアＤを開いた後、まず左右の部分ロック解除レバー５７を操作して部分ロック機構５０のロック状態を解除する。そして、図８に示すように、スロープ板本体２０を支持架台３０に対して前方に（左回りに）回動させ、前方へ車室のフロアＦ上に倒伏させる。この状態で、倒伏したスロープ板本体２０の上に荷物を積むことが可能になる。これにより、スロープ板本体２０が荷物の積み降ろしの邪魔にならなくなる。 Further, in order to load a luggage in the passenger compartment through the opening H at the rear of the vehicle body C, it becomes an obstacle when the slope plate body 20 is in the standing position as shown in FIG. Therefore, after the door D is opened, the left and right partial lock release levers 57 are first operated to release the locked state of the partial lock mechanism 50. And as shown in FIG. 8, the slope board main body 20 is rotated ahead (counterclockwise) with respect to the support stand 30, and is laid down on the floor F of a compartment forward. In this state, it becomes possible to load the luggage on the slope board body 20 that has fallen down. As a result, the slope plate body 20 does not interfere with the loading / unloading of luggage.
　ここで、スロープ板本体２０が前方に倒れた状態では部分ロック機構５０の第２スイッチ６２がオンになるため、第１ソレノイド６４が作動して主ロック解除レバー４７による解除操作が禁止される。これにより、例えば誤って主ロック解除レバー４７に触れても、主ロック機構４０のロック状態が解除されることがない。したがって、スロープ板本体２０が車室のフロアＦ上に倒伏している状態で、支持架台３０のアーム状側板部３２が後側に倒れる虞がない。 Here, since the second switch 62 of the partial lock mechanism 50 is turned on when the slope plate body 20 is tilted forward, the first solenoid 64 is activated and the release operation by the main lock release lever 47 is prohibited. Thereby, for example, even if the main lock release lever 47 is accidentally touched, the lock state of the main lock mechanism 40 is not released. Therefore, there is no possibility that the arm-shaped side plate portion 32 of the support gantry 30 falls to the rear side while the slope plate main body 20 is lying on the floor F of the passenger compartment.
　スロープ板本体２０の上から荷物を全て降ろせば、スロープ板本体２０を再び起立させておくことができる。まず、スロープ板本体２０を支持架台３０に対して上方に（右回りに）回動させる。そして、スロープ板本体２０が図４に示す起立位置まで到達した時点で、左右の各側でスロープ板本体のストライカ５３が支持架台３０のストライカ係合部５５と係合し、部分ロック機構５０がロック状態となる。これにより、スロープ板本体２０が起立位置に保持される。 ¡If all the luggage is unloaded from the top of the slope plate body 20, the slope plate body 20 can be raised again. First, the slope plate body 20 is rotated upward (clockwise) with respect to the support frame 30. When the slope plate main body 20 reaches the standing position shown in FIG. 4, the striker 53 of the slope plate main body is engaged with the striker engaging portion 55 of the support base 30 on each of the left and right sides, and the partial lock mechanism 50 is It becomes locked. Thereby, the slope board main body 20 is hold | maintained in an upright position.
＜本実施形態の長所＞
　本実施形態によると、主ロック機構４０によってスロープ板本体２０を車室内の開口部Ｈ近傍に起立させた状態で保持できる。このため、例えばスロープ装置１０を用いて２台の車椅子を車室の後部に前後に並べて載せても、スロープ板本体２０を車室内の最後部に格納することができる。したがって、車室空間を有効利用できる。 <Advantages of this embodiment>
According to the present embodiment, the slope plate main body 20 can be held in a state where the main lock mechanism 40 stands in the vicinity of the opening H in the vehicle interior. For this reason, for example, even if two wheelchairs are placed side by side on the rear part of the passenger compartment by using the slope device 10, the slope plate body 20 can be stored in the rearmost part of the passenger compartment. Therefore, the vehicle interior space can be used effectively.
　また本実施形態によると、スロープ板本体２０は部分ロック機構５０を解除することによって上記の起立位置から車室内方に倒伏させることができる。このため、例えば、車両に車椅子を乗せない場合には、スロープ板本体２０を起立位置から車室内方に倒伏させることで、このスロープ板本体２０の上に荷物を積むことが可能になる。したがって、スロープ板本体２０が荷物の積み降ろしの邪魔になることがない。即ち、荷物の積み降ろしを行う毎にスロープ板本体２０を外方に展開させる必要がなくなり、荷物の積み降ろし作業が容易になる。 Further, according to the present embodiment, the slope plate main body 20 can be laid down from the above-mentioned standing position toward the vehicle interior by releasing the partial lock mechanism 50. For this reason, for example, when a wheelchair is not put on a vehicle, it is possible to load a load on the slope plate main body 20 by causing the slope plate main body 20 to fall from the standing position toward the vehicle interior. Therefore, the slope plate main body 20 does not interfere with loading / unloading of luggage. In other words, it is not necessary to unfold the slope plate main body 20 every time the load is loaded / unloaded, and the load / unload operation is facilitated.
　また本実施形態によると、図６、図７に示すように支持架台３０の回動中心Ｃ１とスロープ板本体２０の回動中心Ｃ２とがずれているため、主ロック機構４０と部分ロック機構５０とを設置し易くなる。 Further, according to the present embodiment, as shown in FIGS. 6 and 7, the rotation center C1 of the support base 30 and the rotation center C2 of the slope plate main body 20 are shifted, so that the main lock mechanism 40 and the partial lock mechanism 50 are shifted. It becomes easy to install.
　また本実施形態によると、部分ロック機構５０は、スロープ板本体２０の幅の両側に設けられている。このため、誤操作で一方の部分ロック機構５０のロック状態を解除した場合でも、他方の部分ロック機構５０はロック状態に保持されているため、スロープ板本体２０が起立位置から車室側に回動して倒れることがない。 Further, according to the present embodiment, the partial lock mechanisms 50 are provided on both sides of the width of the slope plate body 20. For this reason, even when the locked state of one partial lock mechanism 50 is released by an erroneous operation, the other partial lock mechanism 50 is held in the locked state, so that the slope plate body 20 rotates from the standing position to the vehicle compartment side. And will not fall down.
　また本実施形態によると、主ロック機構４０と部分ロック機構５０のロック状態が同時に解除されることがない。このため、例えば、主ロック機構のロック状態を解除してスロープ板本体２０を車体Ｃの開口部Ｈと地面との間に掛け渡された状態で誤操作により部分ロック機構５０のロック状態を解除しようとしても、部分ロック機構５０のロック状態が解除されることがない。したがって、スロープ装置を用いて車椅子を乗せる途中で、スロープ板本体２０と支持架台３０との連結部位（スロープ板本体２０の回動中心Ｃ２）が折れ曲がるような不具合を防止できる。 Further, according to the present embodiment, the lock state of the main lock mechanism 40 and the partial lock mechanism 50 is not released at the same time. For this reason, for example, the lock state of the main lock mechanism is released, and the lock state of the partial lock mechanism 50 is released by an erroneous operation in a state where the slope plate body 20 is stretched between the opening H of the vehicle body C and the ground. However, the lock state of the partial lock mechanism 50 is not released. Therefore, it is possible to prevent a problem that the connecting portion (the rotation center C2 of the slope plate main body 20) between the slope plate main body 20 and the support base 30 is bent while the wheelchair is put on the slope device.
［第２の実施形態］
　上述の第１の実施形態では、第１、第２スイッチ６１，６２と第１、第２ソレノイド６４，６５を有する電気的なインターロック装置により、主ロック機構４０と部分ロック機構５０のロック状態を同時に解除できない構成とした。以下に説明する第２の実施形態では、電気的なインターロック装置が、機械的なインターロック装置に置き換えられている。 [Second Embodiment]
In the above-described first embodiment, the main lock mechanism 40 and the partial lock mechanism 50 are locked by the electrical interlock device having the first and second switches 61 and 62 and the first and second solenoids 64 and 65. It was set as the structure which cannot cancel | release simultaneously. In the second embodiment described below, the electrical interlock device is replaced with a mechanical interlock device.
　具体的には図１２Ａ～Ｃに示すように、機械的なインターロック装置７０は、ストライカ４３，５３が前方から当接する動作や前方へ離れる動作を検出するための検出板７１を備えている。検出板７１は、主ロック機構４０と部分ロック機構５０のストライカ係合部４５，５５（図４参照）に収容されている。検出板７１は、前後に延びる中央板７１ｍを有している。検出板７１はまた、中央板７１ｍから上方の前方に延びる上検出板７１ｕと、下方の前方に延びる下検出板７１ｄを有している。上検出板７１ｕと下検出板７１ｄは、中央板７１ｍに一体的に結合されている。 Specifically, as shown in FIGS. 12A to 12C, the mechanical interlock device 70 includes a detection plate 71 for detecting an operation in which the strikers 43 and 53 abut from the front and an operation in which the strikers 43 and 53 are separated from the front. The detection plate 71 is accommodated in the striker engaging portions 45 and 55 (see FIG. 4) of the main lock mechanism 40 and the partial lock mechanism 50. The detection plate 71 has a central plate 71m extending in the front-rear direction. The detection plate 71 also has an upper detection plate 71u extending forward from the center plate 71m and a lower detection plate 71d extending forward and downward. The upper detection plate 71u and the lower detection plate 71d are integrally coupled to the center plate 71m.
　検出板７１は、中央板７１ｍの後端部に設けられた支軸７１ａを支点として回動でき、且つこの支軸７１ａが前後方向にのみ移動できるように、支持架台３０のアーム状側板部３２に連結されている。また、検出板７１はこの支軸７１ａに取り付けられたバネ７１ｓによって前方に付勢されている。上検出板７１ｕは、その前端でスロープ板側のストライカ５３を受けることができる位置に配置されている。同様に下検出板７１ｄは、その前端で車体側のストライカ４３を受けることができる位置に配置されている。 The detection plate 71 can rotate with a support shaft 71a provided at the rear end portion of the center plate 71m as a fulcrum, and the support shaft 71a can move only in the front-rear direction. It is connected to. The detection plate 71 is urged forward by a spring 71s attached to the support shaft 71a. The upper detection plate 71u is disposed at a position where it can receive the striker 53 on the slope plate side at its front end. Similarly, the lower detection plate 71d is arranged at a position where the front end thereof can receive the striker 43 on the vehicle body side.
　インターロック装置７０はまた、検出板７１の動作に応じて主ロック解除レバー４７または部分ロック解除レバー５７の回動を規制する横板部材７４を備えている。横板部材７４は、ほぼ水平に前後に延びる板部材であり、その中央部を支点として回動可能にロック解除ボックス６０ｂに連結されている。横板部材７４は、後端部に取付けられたバネ７７によって下方に付勢されている。横板部材７４は前後両端部に、主ロック解除レバー４７と部分ロック解除レバー５７の回動を妨げるための突起を有している。横板部材７４は回動により後端部が上昇すると、後端部の突起が主ロック解除レバー４７の後方への回動を妨げ、主ロック解除レバー４７による解除操作が禁止される。同様に横板部材７４は回動により前端部が上昇すると、部分ロック解除レバー５７の前方への回動を妨げ、部分ロック解除レバー５７による解除操作が禁止される。 The interlock device 70 also includes a horizontal plate member 74 that restricts the rotation of the main lock release lever 47 or the partial lock release lever 57 according to the operation of the detection plate 71. The horizontal plate member 74 is a plate member that extends substantially horizontally back and forth, and is connected to the unlocking box 60b so as to be rotatable about the central portion thereof. The horizontal plate member 74 is urged downward by a spring 77 attached to the rear end. The horizontal plate member 74 has protrusions for preventing the main lock release lever 47 and the partial lock release lever 57 from rotating at both front and rear ends. When the rear end of the horizontal plate member 74 is raised by the rotation, the protrusion at the rear end prevents the main lock release lever 47 from rotating backward, and the release operation by the main lock release lever 47 is prohibited. Similarly, when the front end of the horizontal plate member 74 is raised by rotation, the partial lock release lever 57 is prevented from rotating forward, and the release operation by the partial lock release lever 57 is prohibited.
　横板部材７４の前端部は、動作を伝達するワイヤー７５により、前記の検出板７１の中央板７１ｍの前端部と連結されている。中央板７１ｍの前端部が下方に動くと、その動作によりワイヤー７５が引かれて横板部材７４の前端部が下方に動く。そして横板部材７４は、ワイヤー７５の張力とバネ７７の付勢力のバランスする位置で止まる。ここで、ワイヤー７５の長さは適切に調整されて、検出板７１が原位置にあるときに横板部材７４がほぼ水平となる。 The front end portion of the horizontal plate member 74 is connected to the front end portion of the center plate 71m of the detection plate 71 by a wire 75 that transmits the operation. When the front end portion of the central plate 71m moves downward, the wire 75 is pulled by the operation, and the front end portion of the horizontal plate member 74 moves downward. The horizontal plate member 74 stops at a position where the tension of the wire 75 and the biasing force of the spring 77 are balanced. Here, the length of the wire 75 is adjusted appropriately, and the horizontal plate member 74 becomes substantially horizontal when the detection plate 71 is in the original position.
　スロープ板本体２０が支持架台３０と共に起立位置に保持されている時は、図１２Ａに示すように下検出板７１ｄと上検出板７１ｕがそれぞれ車体側のストライカ４３とスロープ板側のストライカ５３によって同時に後方に押されている。したがって、検出板７１はバネ７１ｓの付勢力に抗って後方へ移動する一方で、検出板７１は支軸７１ａの上下それぞれで後方に押されているためバランスがとれて支軸７１ａの周りに回動することはない（以下、原位置という）。 When the slope plate main body 20 is held in the standing position together with the support base 30, as shown in FIG. 12A, the lower detection plate 71d and the upper detection plate 71u are simultaneously formed by the striker 43 on the vehicle body side and the striker 53 on the slope plate side, respectively. It is pushed backwards. Therefore, the detection plate 71 moves backward against the urging force of the spring 71s, while the detection plate 71 is pushed rearward on the upper and lower sides of the support shaft 71a so that the balance is achieved and the support shaft 71a is moved around. It does not rotate (hereinafter referred to as the original position).
　部分ロック機構５０のロック状態を解除してスロープ板本体２０を前方に倒すと、図１２Ｂに示すように上検出板７１ｕからスロープ板側のストライカ５３が離れるが、下検出板７１ｄは車体側のストライカ４３によって後方に押されたままである。したがって、検出板７１はバネ７１ｓの付勢力により支軸７１ａの周りに原位置から一定角度だけ左回りに回動する。この回動により中央板７１ｍの前端部が下方に動いて、ワイヤー７５を介して横板部材７４の前端部が下方に引かれ、横板部材７４はバネ７７の付勢力に抗して図１２Ｂに示すように左回りに回動する。これにより、横板部材７４の後端部が上昇して主ロック解除レバー４７の回動を妨げ、主ロック解除レバー４７による解除操作が禁止される。 When the lock state of the partial lock mechanism 50 is released and the slope plate body 20 is tilted forward, the striker 53 on the slope plate side is separated from the upper detection plate 71u as shown in FIG. 12B, but the lower detection plate 71d is on the vehicle body side. It remains pushed backward by the striker 43. Therefore, the detection plate 71 is rotated counterclockwise by a predetermined angle from the original position around the support shaft 71a by the biasing force of the spring 71s. By this rotation, the front end of the central plate 71m moves downward, the front end of the horizontal plate member 74 is pulled downward via the wire 75, and the horizontal plate member 74 resists the biasing force of the spring 77 as shown in FIG. As shown in FIG. As a result, the rear end of the horizontal plate member 74 rises to prevent the main lock release lever 47 from rotating, and the release operation by the main lock release lever 47 is prohibited.
　また、主ロック機構４０のロック状態を解除してスロープ板本体２０を支持架台３０と共に後方に倒すと、図１２Ｃに示すように下検出板７１ｄから車体側のストライカ４３が離れるが、上検出板７１ｕはスロープ板側のストライカ５３によって後方に押されたままである。したがって、検出板７１はバネ７１ｓの付勢力により支軸７１ａの周りに原位置から一定角度だけ右回りに回動する。この回動により中央板７１ｍの前端部が上方に動いて、横板部材７４の前端部を引いているワイヤー７５の張力が緩み、横板部材７４はバネ７７の付勢力で図１２Ｃに示すように右回りに回動する。これにより、横板部材７４の前端部が上昇して部分ロック解除レバー５７の回動を妨げ、部分ロック解除レバー５７による解除操作が禁止される。 When the main locking mechanism 40 is unlocked and the slope plate main body 20 is tilted backward together with the support frame 30, the striker 43 on the vehicle body side is separated from the lower detection plate 71d as shown in FIG. 71u remains pushed backward by the striker 53 on the slope plate side. Therefore, the detection plate 71 is rotated clockwise by a predetermined angle from the original position around the support shaft 71a by the biasing force of the spring 71s. By this rotation, the front end portion of the central plate 71m moves upward, and the tension of the wire 75 pulling the front end portion of the horizontal plate member 74 is loosened. The horizontal plate member 74 is biased by the spring 77 as shown in FIG. Rotate clockwise. As a result, the front end of the horizontal plate member 74 rises to prevent the partial lock release lever 57 from rotating, and the release operation by the partial lock release lever 57 is prohibited.
［第３の実施形態］
　部分ロック機構５０とロック解除機構は、図１３に示すように、スロープ板本体２０の端縁に横スライド可能に取付けられたスライドバー８１と、支持架台３０のアーム状側板部３２に取付けられた環状の受け具８３とを有する、周知のかんぬきロックとして構成することも可能である。スライドバー８１をスライドさせて受け具８３に通すことで、支持架台２０に対するスロープ板本体２０の回動が禁止される。 [Third Embodiment]
As shown in FIG. 13, the partial lock mechanism 50 and the lock release mechanism are attached to the slide bar 81 that is slidably mounted on the edge of the slope plate body 20 and the arm-shaped side plate portion 32 of the support frame 30. It is also possible to configure as a well-known hammer lock having an annular receiver 83. By sliding the slide bar 81 and passing it through the receiver 83, the rotation of the slope plate body 20 with respect to the support base 20 is prohibited.
［第４の実施形態］
　また、部分ロック機構５０とそのロック解除機構を、図１４に示すように、スロープ板本体２０の端縁に設けられた角型のループ８５ｗと、支持架台２０のアーム状側板部３２に取付けられたフック８７とを有する、周知のラッチロックとして構成することも可能である。ループ８５ｗをフック８７に掛け、操作部８５を操作してループ８５ｗを引き締めることによって、支持架台２０に対するスロープ板本体２０の回動が禁止される。 [Fourth Embodiment]
Further, as shown in FIG. 14, the partial lock mechanism 50 and the lock release mechanism are attached to a square loop 85 w provided on the edge of the slope plate body 20 and the arm-shaped side plate portion 32 of the support frame 20. It is also possible to configure as a well-known latch lock having a hook 87. By turning the loop 85w on the hook 87 and operating the operation portion 85 to tighten the loop 85w, the rotation of the slope plate body 20 with respect to the support base 20 is prohibited.
　本発明の各種実施形態は、上述の態様を例に説明したが、本発明の目的を逸脱せずに多くの交代、改良、変更が可能であることは当業者であれば明らかである。したがって本発明の実施形態は、添付した請求項の精神と目的と逸脱しない全ての交代、改良、変更を含み得る。例えば、本発明の実施形態は、上述の特定の態様に限定されず、下記のように変更が可能である。 Various embodiments of the present invention have been described by taking the above-described embodiment as an example, but it will be apparent to those skilled in the art that many alternations, improvements, and changes can be made without departing from the object of the present invention. Accordingly, embodiments of the invention may include all alterations, modifications, and variations that do not depart from the spirit and scope of the appended claims. For example, the embodiment of the present invention is not limited to the specific aspect described above, and can be modified as follows.
　第１の実施形態において、第１、第２スイッチ６１，６２は、ストライカ係合部４５，５５とストライカ４３，５３が係合する動作や係合が解ける動作とは関係なく、単に支持架台３０とスロープ板本体２０が回動する動作によってオンとなるように構成を変更することもできる。具体的には、第１スイッチは支持架台３０のうち車体Ｃに対面し得る箇所に設けられる。そして、主ロック機構４０によって支持架台３０が車体Ｃに対して固定されているときには、対面する車体Ｃによって押圧されて第１スイッチがオフとなっている。主ロック機構４０によるロックを解除し、支持架台３０を後方に回動させると、車体Ｃが第１スイッチから離れ、押圧力が除去されて第１スイッチがオンとなる。第２スイッチも同様に、支持架台３０のうちスロープ板本体２０に対面し得る箇所に設けて、スロープ板本体２０の回動動作によりオンとなるように構成することができる。 In the first embodiment, the first and second switches 61 and 62 are simply the support frame 30 regardless of the operation in which the striker engaging portions 45 and 55 and the strikers 43 and 53 are engaged or the operation in which the engagement is released. It is also possible to change the configuration so that the slope plate body 20 is turned on by the rotating operation. Specifically, the first switch is provided on the support frame 30 at a location where it can face the vehicle body C. And when the support stand 30 is being fixed with respect to the vehicle body C by the main lock mechanism 40, it is pressed by the vehicle body C which faces, and the 1st switch is turned off. When the lock by the main lock mechanism 40 is released and the support frame 30 is rotated backward, the vehicle body C is separated from the first switch, the pressing force is removed, and the first switch is turned on. Similarly, the second switch can be provided at a location where the support plate 30 can face the slope plate main body 20 and can be turned on by the rotation of the slope plate main body 20.
　上記各実施形態において、スロープ装置１０は、車体Ｃ後側の開口部Ｈに設置するのみならず、車体側面の開口部に設けることも可能である。
                                                                                 In each of the above embodiments, the slope device 10 can be provided not only in the opening H on the rear side of the vehicle body C but also in the opening on the side surface of the vehicle body.
