Description

オットマン装置Ottoman equipment
 本発明は、車両などの座席下部に格納可能な状態で取り付けられるオットマン装置に関する。 The present invention relates to an ottoman device that can be stored in a lower part of a seat of a vehicle or the like.
 従来より、座席下部に取り付けられ、フットレストプレートを座席前方へ展開する展開動作と、フットレストプレートを座席下部に格納する格納動作とが可能な格納式のオットマン装置が高級車などで採用されている。フットレストプレートを格納するための機構は、様々であるが、四点リンク機構を利用したものが一般的となっている(例えば特許文献1~4を参照)。しかし、この種のオットマン装置においては、フットレストプレートを座席の前方へ大きく迫り出させることが困難であった。というのも、この種のオットマン装置において、迫出量を大きく確保しようとすると、四点リンク機構を構成するリンク節を長くする必要があるものの、車両の座席下部のスペースは限られており、リンク節を長くすることができなかったからである。 Conventionally, a retractable ottoman device attached to the lower part of the seat and capable of deploying the footrest plate in front of the seat and retracting the footrest plate in the lower part of the seat has been adopted in high-class vehicles. There are various mechanisms for storing the footrest plate, but a mechanism using a four-point link mechanism is generally used (see, for example, Patent Documents 1 to 4). However, in this type of ottoman device, it has been difficult to cause the footrest plate to largely protrude toward the front of the seat. This is because, in this type of ottoman device, when trying to secure a large amount of protrusion, it is necessary to lengthen the link node constituting the four-point link mechanism, but the space under the seat of the vehicle is limited, This is because the link clause could not be lengthened.
 このような実状に鑑みてか、これまでには、フットレストプレートを前方へ迫り出ことができるようにしたオットマン装置も提案されている(例えば特許文献5,6を参照)。しかし、これらのオットマン装置はいずれも、フットレストプレートを座席下部から座席前方へ展開した後に、フットレストプレートを前方へ迫り出させる動作を別途行わなければならず、操作が非常に煩わしかった。一連の操作でフットレストプレートの展開動作と迫出動作とを行うことができるオットマン装置が望まれている。 In view of such a situation, so far, an ottoman device has been proposed in which the footrest plate can be pushed forward (see, for example, Patent Documents 5 and 6). However, all of these ottoman devices have to perform a separate operation of pushing the footrest plate forward after the footrest plate is deployed from the lower part of the seat to the front of the seat, and the operation is very troublesome. There is a demand for an ottoman device that can perform a footrest plate unfolding operation and an ejection operation by a series of operations.

 本発明は、上記課題を解決するものであり、一連の簡単な操作でフットレストプレートの展開動作と迫出動作とを行うことができ、座席下部のスペースを広く確保できない場合であっても、フットレストプレートを座席前方へ大きく迫り出させることが可能なオットマン装置を提供するものである。 The present invention solves the above-described problem, and can perform the unfolding operation and the pushing-out operation of the footrest plate by a series of simple operations, and even when the space below the seat cannot be secured widely, It is an object of the present invention to provide an ottoman device capable of causing a plate to largely protrude toward the front of a seat.

The above issues
An ottoman device attached to the lower part of the seat and capable of deploying the footrest plate in front of the seat and retracting the footrest plate in the lower part of the seat by a four-point link mechanism,
The problem is solved by providing an ottoman device that includes an interlocking ejection mechanism that causes the footrest plate to squeeze forward in conjunction with the unfolding operation and retreats the footrest plate in conjunction with the retracting operation.
 本発明のオットマン装置において、連動迫出機構の具体的な構成は、例えば、連動迫出機構を、前記四点リンク機構の回動動作を直線運動に変換することによりフットレストプレートを迫り出し又は後退させるスライド機構を利用することで具現化した。また、連動迫出機構を、フットレストプレートの前端部に回動可能に設けられた可動部を上方に回動させることによりフットレストプレートを実質的に迫り出させ、前記可動部を下方に回動させることによりフットレストプレートを実質的に後退させる跳上げ機構を利用したものとする。これらのスライド機構や跳上げ機構の具体的な構成については、後で詳しく説明する。 In the ottoman device of the present invention, the specific structure of the interlocking ejection mechanism is, for example, that the interlocking ejection mechanism projects or retracts the footrest plate by converting the rotational movement of the four-point link mechanism into a linear motion. Realized by using a sliding mechanism. Further, the interlocking ejection mechanism causes the footrest plate to be substantially ejected by pivoting the movable portion provided rotatably at the front end portion of the footrest plate, and pivots the movable portion downward. Thus, it is assumed that a jumping mechanism that substantially retracts the footrest plate is used. Specific configurations of the slide mechanism and the jumping mechanism will be described in detail later.
 ところで、スライド機構を利用したタイプのオットマン装置においては、前記四点リンク機構に滑車機構を組み合わせることにより、フットレストプレートの迫出量が増大されるようにすると好ましい。これにより、フットレストプレートの迫出量を、滑車機構を設けない場合の約2倍まで増大させることが可能になる。この滑車機構の具体的な構成については、後で詳しく説明する。 By the way, in an ottoman device of a type using a slide mechanism, it is preferable that the amount of protrusion of the footrest plate is increased by combining a pulley mechanism with the four-point link mechanism. Thereby, it is possible to increase the protruding amount of the footrest plate to about twice that in the case where the pulley mechanism is not provided. The specific configuration of this pulley mechanism will be described in detail later.
 また、本発明のオットマン装置においては、迫り出し状態にあるフットレストプレートの前方から異常負荷が掛かった際にフットレストプレートを後退させる安全機構を備えることも好ましい。オットマン装置は、車両の後部座席などに採用すると、不意に前の座席が後方へ大きくスライドされたような場合には、足が挟まれるおそれがある。しかし、上記の安全機構を設けることにより、足が挟まれた状態となっても、その力を後方へ逃がすことができるので、ケガをしないようにすることができる。 Also, the ottoman device of the present invention preferably includes a safety mechanism that retracts the footrest plate when an abnormal load is applied from the front of the footrest plate that is in the protruding state. When the ottoman device is adopted as a rear seat of a vehicle, the foot may be caught when the front seat is unexpectedly slid rearward. However, by providing the above-described safety mechanism, even if the foot is in a state of being pinched, the force can be released to the rear, so that injury can be prevented.
 さらに、本発明のオットマン装置においては、迫り出し状態にあるフットレストプレートの角度を調節するための角度調節機構を備えることも好ましい。これにより、座席に着席した人の足の長さやふくらはぎの形状に応じて、フットレストプレートの上面がふくらはぎの裏側にやさしく接触するようにフットレストプレートの角度を調節することが可能になり、座席の座り心地を向上することができる。 Furthermore, the ottoman device of the present invention preferably includes an angle adjusting mechanism for adjusting the angle of the footrest plate in the protruding state. This makes it possible to adjust the angle of the footrest plate so that the upper surface of the footrest plate gently touches the back of the calf according to the length of the person's feet and the shape of the calf. Comfort can be improved.
 さらにまた、本発明のオットマン装置を、フットレストプレートに荷重が掛かった際に前記四点リンク機構をロックするロック機構と、該ロック機構を解除するためのロック解除機構とで構成されたフットレストプレート高さ調節機構を備えたものとすることも好ましい。ロック機構の具体的な構成は、例えば、ロック機構を、前記荷重が掛かった際にロックバネが巻増し方向に引っ張られて前記四点リンク機構におけるいずれかの軸の外周部を締め付け、ロック解除機構が作動した際に前記ロックバネの軸に対する締め付けが解除される締付型ロックバネ機構を利用して具現化した。また、ロック機構を、前記荷重が掛かった際にロックバネが拡径方向に押し込まれて前記四点リンク機構におけるドラムの内部で張り出して該可動軸の内周面に密着した状態となり、ロック解除機構が作動した際に前記ロックバネの張り出した状態が解除される張出型ロックバネ機構を利用したものとすることも好ましい。これら締付型ロックバネ機構と張出型ロックバネ機構は、いずれも簡素でありながら、フットレストプレートの高さ調節を無段階で可能とする。加えて、フットレストプレートに足を載せた際には、ロックバネが前記の軸又はドラムを締め付けるか張り出すかによって、フットレストプレートが下方へ沈み込まないように確実にロックすることを可能とする。 Furthermore, the ottoman device according to the present invention has a footrest plate height composed of a lock mechanism that locks the four-point link mechanism when a load is applied to the footrest plate, and a lock release mechanism that releases the lock mechanism. It is also preferable to provide a thickness adjusting mechanism. A specific configuration of the lock mechanism is, for example, a lock release mechanism in which the lock spring is pulled in the winding direction when the load is applied, and the outer peripheral portion of one of the shafts in the four-point link mechanism is tightened. This is realized by using a tightening type lock spring mechanism that releases the tightening of the lock spring with respect to the shaft when the is operated. Further, when the load is applied to the lock mechanism, the lock spring is pushed in the diameter-expanding direction so as to protrude inside the drum in the four-point link mechanism and come into close contact with the inner peripheral surface of the movable shaft. It is also preferable to use an overhanging lock spring mechanism that releases the overhanging state of the lock spring when the is operated. The tightening type lock spring mechanism and the overhang type lock spring mechanism are both simple, but can adjust the height of the footrest plate steplessly. In addition, when the foot is placed on the footrest plate, the lockrest can be surely locked so that the footrest plate does not sink downward depending on whether the shaft or the drum is tightened or extended.

 本発明のオットマン装置の好適な実施態様について、図面を用いてより具体的に説明する。以下においては、第一実施態様から第五実施態様までの5つの実施態様を例に挙げて本発明のオットマン装置を説明するが、本発明のオットマン装置の技術的範囲はこれらの構成に限定されることなく、その趣旨を損なわない範囲で適宜変更を施すことができる。 A preferred embodiment of the ottoman device of the present invention will be described more specifically with reference to the drawings. In the following, the ottoman device of the present invention will be described by taking five embodiments from the first embodiment to the fifth embodiment as examples, but the technical scope of the ottoman device of the present invention is limited to these configurations. Without departing from the spirit of the present invention.
1.第一実施態様のオットマン装置
 まず、第一実施態様のオットマン装置について説明する。図1は、第一実施態様のオットマン装置10の展開状態(実線部)と格納状態(二点鎖線部)を示した側面図である。第一実施態様のオットマン装置10は、図1に示すように、座席50の下部に取り付けられ、フットレストプレート11を座席50の前方へ展開する展開動作と、フットレストプレート11を座席50の下部に格納する格納動作とが四点リンク機構12によって可能とされたものとなっており、展開動作に連動してフットレストプレート11を前方へ迫り出させる(前方へ突き出る距離を図1における距離ΔL分増大させる)とともに、格納動作に連動してフットレストプレート11を後退させる連動迫出機構13を備えたものとなっている。四点リンク機構12は、フットレストプレート取付部12aと、第一リンク12bと、第二リンク12cと、第三リンク12dと、第四リンク12eと、座席取付部12fとを点P~Pで相対的に回動可能に連結した構造としている。
1. First, the ottoman device of the first embodiment will be described. FIG. 1 is a side view showing an unfolded state (solid line portion) and a retracted state (two-dot chain line portion) of the ottoman device 10 of the first embodiment. As shown in FIG. 1, the ottoman device 10 according to the first embodiment is attached to the lower portion of the seat 50, and unfolds the footrest plate 11 in front of the seat 50 and stores the footrest plate 11 in the lower portion of the seat 50. The four-point link mechanism 12 enables the storing operation to be performed, and the footrest plate 11 is pushed forward in conjunction with the unfolding operation (the distance protruding forward is increased by the distance ΔL in FIG. 1). ) And an interlocking ejection mechanism 13 that retracts the footrest plate 11 in conjunction with the retracting operation. The four-point link mechanism 12 connects the footrest plate mounting portion 12a, the first link 12b, the second link 12c, the third link 12d, the fourth link 12e, and the seat mounting portion 12f to the points P 1 to P 7. It is set as the structure connected so that relative rotation was possible.
 連動迫出機構13は、各種のものを採用できるが、第一実施態様のオットマン装置においては、四点リンク機構12の回動動作を直線運動に変換することによりフットレストプレート11を迫り出し又は後退させるスライド機構を利用したものとしている。具体的には、フットレストプレート11を、フットレストプレート取付部12aに対して前後方向へ相対的にスライド可能な状態で固定するとともに、第一リンク12bをその先端部側(点P側の端部)が延長された構造とし、その延長された先端部に支点(点Q)を設けてコイルバネ14aを介してフットレストプレート11と連結した構造としている。これにより、展開動作に連動して、フットレストプレート11が第一リンク12bの先端部によって前方に迫り出され、格納動作に連動して、フットレストプレート11が第一リンク12bの先端部によって後退させられるようになる。連動迫出機構13による迫出量Lの増加分ΔLは、特に限定されないが、通常、30~100mm程度とされる。迫出量Lの増加分ΔLは、点Pと点Qの距離を変えることで変更することができる。 Various interlocking ejecting mechanisms 13 can be employed, but in the ottoman device of the first embodiment, the footrest plate 11 is ejected or retracted by converting the rotational movement of the four-point link mechanism 12 into a linear motion. The slide mechanism is used. Specifically, the footrest plates 11, is fixed in a relatively slidable state in the front-rear direction with respect to the footrest plate mounting portion 12a, an end portion of the first link 12b and the tip end (point P 1 side ) Is extended, and a fulcrum (point Q 1 ) is provided at the extended tip, and is connected to the footrest plate 11 via a coil spring 14a. Accordingly, the footrest plate 11 is pushed forward by the distal end portion of the first link 12b in conjunction with the unfolding operation, and the footrest plate 11 is retracted by the distal end portion of the first link 12b in conjunction with the retracting operation. It becomes like this. The increase ΔL of the amount of ejection L by the interlocking ejection mechanism 13 is not particularly limited, but is usually about 30 to 100 mm. The increase ΔL of the amount of protrusion L can be changed by changing the distance between the point P 1 and the point Q 1 .
 ところで、第一実施態様のオットマン装置10は、迫り出し状態にあるフットレストプレート11の前方から異常負荷が掛かった際にフットレストプレート11を後退させる安全機構14を備えたものとなっている。具体的には、フットレストプレート11を前方に付勢するためのコイルバネ14aを安全機構14としてフットレストプレート11の裏側に設けている。コイルバネ14aの基端部は、フットレストプレート取付部12aに連結されており、コイルバネ14aの先端部は、フットレストプレート11の裏面に設けられたバネ受け部11aに押し当てられた状態となっている。このため、通常時のフットレストプレート11は、前方に迫り出した状態となっているものの、前方から負荷が掛かった際には、フットレストプレート11がコイルバネ14aに抗って後退するようになっている。 By the way, the ottoman device 10 of the first embodiment includes a safety mechanism 14 that retracts the footrest plate 11 when an abnormal load is applied from the front of the footrest plate 11 in the protruding state. Specifically, a coil spring 14 a for biasing the footrest plate 11 forward is provided as a safety mechanism 14 on the back side of the footrest plate 11. The base end portion of the coil spring 14 a is connected to the footrest plate mounting portion 12 a, and the distal end portion of the coil spring 14 a is pressed against the spring receiving portion 11 a provided on the back surface of the footrest plate 11. For this reason, the footrest plate 11 in a normal state is in a state of protruding forward, but when a load is applied from the front, the footrest plate 11 is retracted against the coil spring 14a. .
 また、第一実施態様のオットマン装置10には、フットレストプレート11の高さを調節するためのフットレストプレート高さ調節機構を設けている。このフットレストプレート高さ調節機構は、フットレストプレート11に荷重が掛かった際に四点リンク機構12をロックするロック機構20と、ロック機構20を解除するためのロック解除機構30(図2~4を参照)とで構成されている。ロック機構20は、上述した通り、締付型ロックバネ機構と張出型ロックバネ機構を好適に採用することができるが、ここでは、図2~4に示すように、張出型ロックバネ機構を採用している。図2は、第一実施態様のオットマン装置10において、ロック状態にある張出型ロックバネ機構(ロック機構20)の周辺を拡大して示した側面図である。図3は、第一実施態様のオットマン装置10において、ロック解除状態にある張出型ロックバネ機構(ロック機構20)の周辺を拡大して示した側面図である。図4は、第一実施態様のオットマン装置10において、張出型ロックバネ機構(ロック機構20)の周辺をロック軸40の中心を通る平面で切断した状態を示した断面図である。図2と図3においては、図示の便宜上、一部の部材を透過して描いている。ロック解除機構30は、自転車のブレーキなどに採用される、操作ワイヤー31と操作ワイヤー31を内挿する外筒体32とで構成されるものを採用している。 Further, the ottoman device 10 of the first embodiment is provided with a footrest plate height adjusting mechanism for adjusting the height of the footrest plate 11. The footrest plate height adjusting mechanism includes a lock mechanism 20 that locks the four-point link mechanism 12 when a load is applied to the footrest plate 11, and an unlock mechanism 30 (see FIGS. 2 to 4) for releasing the lock mechanism 20. Reference). As described above, the lock mechanism 20 can preferably employ a tightening type lock spring mechanism and an overhang type lock spring mechanism. Here, as shown in FIGS. 2 to 4, an overhang type lock spring mechanism is employed. ing. FIG. 2 is an enlarged side view of the periphery of the overhanging lock spring mechanism (lock mechanism 20) in the locked state in the ottoman device 10 of the first embodiment. FIG. 3 is an enlarged side view of the periphery of the overhanging lock spring mechanism (lock mechanism 20) in the unlocked state in the ottoman device 10 of the first embodiment. FIG. 4 is a cross-sectional view showing a state in which the periphery of the overhang type lock spring mechanism (lock mechanism 20) is cut by a plane passing through the center of the lock shaft 40 in the ottoman device 10 of the first embodiment. In FIG. 2 and FIG. 3, for convenience of illustration, some members are drawn through. The lock release mechanism 30 employs a mechanism constituted by an operation wire 31 and an outer cylindrical body 32 into which the operation wire 31 is inserted, which is employed for a bicycle brake or the like.
 この張出型ロック機構20は、図2~4に示すように、ドラム21と、ロックバネ22と、先端受けパイプ23と、第一ロックバネ緩め片24と、第一ロックバネ緩め部材25と、第二ロックバネ緩め片26と、第二ロックバネ緩め部材27と、ロックバネ固定部材28と、リターンバネ29とを備えたものとなっており、ロックバネ22は、そのコイル部の外周がドラム21の内周に密着した状態で組み込まれ、その端部が段状に折り曲げられて先端受けパイプ23の外周で受けられた構造となっている。図2に示すロック状態においては、ロックバネ固定部材28がロックバネ22の端部と接触してコイルバネ22が拡径され、第四リンク12eが座席取付部12fに対して回動することができない状態になる。第一実施態様のオットマン装置10では、2本のロックバネ22を組み込んでおり、上下両方向への回転をロックすることができるようにしている。一方、図2に示すロック状態から、座席脇などに設けた図示省略のフットレストプレート高さ調節用操作レバーを操作すると、操作ワイヤー31が引き込まれて、第一ロックバネ緩め部材25と第二ロックバネ緩め部材27とが点Pを中心として互いに近づく向きに回動する(図3)。このとき、第一ロックバネ緩め部材25及び第二ロックバネ緩め部材27にそれぞれ一体的に設けられた第一ロックバネ緩め片24及び第二ロックバネ緩め片26がロックバネ自由端22aを緩め側(ロックバネ22の外径が小さくなる側)に押圧してロックバネ22の張り出した状態が解除され、ロック状態が解除されるようになっている。このとき、フットレストプレート11の高さを調節することができるようになる。また、段状に折り曲げられたロックバネ22の端部を先端受けパイプ23で受けたことにより、フットレストプレート11に過大な負荷が掛かった場合であってもロックバネ端部の変形を防ぎ、ロック状態が確実に維持されるようにして安全性を高めている。 As shown in FIGS. 2 to 4, the overhang type lock mechanism 20 includes a drum 21, a lock spring 22, a tip receiving pipe 23, a first lock spring loosening piece 24, a first lock spring loosening member 25, and a second lock spring. The lock spring loosening piece 26, the second lock spring loosening member 27, the lock spring fixing member 28, and the return spring 29 are provided. The outer circumference of the coil portion of the lock spring 22 is in close contact with the inner circumference of the drum 21. The end portion is bent in a step shape and is received by the outer periphery of the tip receiving pipe 23. In the locked state shown in FIG. 2, the lock spring fixing member 28 comes into contact with the end of the lock spring 22, the diameter of the coil spring 22 is expanded, and the fourth link 12e cannot rotate with respect to the seat mounting portion 12f. Become. In the ottoman device 10 of the first embodiment, two lock springs 22 are incorporated so that the rotation in both the upper and lower directions can be locked. On the other hand, when a not-illustrated footrest plate height adjustment lever provided on the side of the seat is operated from the locked state shown in FIG. 2, the operation wire 31 is pulled, and the first lock spring loosening member 25 and the second lock spring loosened. rotated in a direction to approach each other around the member 27 cusp P 7 (Fig. 3). At this time, the first lock spring loosening piece 24 and the second lock spring loosening piece 26 provided integrally with the first lock spring loosening member 25 and the second lock spring loosening member 27 respectively loosen the lock spring free end 22a (outside the lock spring 22). The protruding state of the lock spring 22 is released by pressing toward the diameter decreasing side, and the locked state is released. At this time, the height of the footrest plate 11 can be adjusted. Further, by receiving the end portion of the lock spring 22 bent in a step shape with the tip receiving pipe 23, even when an excessive load is applied to the footrest plate 11, deformation of the lock spring end portion is prevented, and the lock state is maintained. Safety is enhanced by ensuring that it is maintained.
2.第二実施態様のオットマン装置
 続いて、第二実施態様のオットマン装置について説明する。図5は、第二実施態様のオットマン装置10におけるフットレストプレート11の周辺を拡大して示した側面図である。第二実施態様のオットマン装置10は、図5に示すように、四点リンク機構12に滑車機構15を組み合わせることにより、フットレストプレート11の迫出量ΔLが倍増されたものとなっている。滑車機構15は、第一リンク12bの先端部に軸支された動滑車15aと、動滑車15aに掛け回されたワイヤー15とで構成している。ワイヤー15の一端部は、フットレストプレート11の裏面に設けられたワイヤー連結部11bに連結され(図5の点Q)、ワイヤー15の他端部は、フットレスト取付部12aに設けられたワイヤー連結部12gに連結されている(図5の点Q)。
2. Next, the ottoman device of the second embodiment will be described. FIG. 5 is an enlarged side view of the periphery of the footrest plate 11 in the ottoman device 10 of the second embodiment. As shown in FIG. 5, the ottoman device 10 according to the second embodiment is configured such that the amount of protrusion ΔL of the footrest plate 11 is doubled by combining the pulley mechanism 15 with the four-point link mechanism 12. The pulley mechanism 15 includes a moving pulley 15a that is pivotally supported at the tip of the first link 12b, and a wire 15 that is wound around the moving pulley 15a. One end portion of the wire 15 is connected to a wire connecting portion 11b provided on the back surface of the footrest plate 11 (point Q 3 in FIG. 5), and the other end portion of the wire 15 is connected to a wire provided to the footrest attaching portion 12a. It is connected to the part 12g (point Q 2 in FIG. 5).
 このように、第一リンク12bの先端部を、動滑車15aとワイヤー15bを介してフットレストプレート11に連結することにより、展開動作に伴って第一リンク12bの先端部が前方へ移動すると、動滑車15aも前方へ移動し、それに掛け回されたワイヤー15bもその中途部分を動滑車15aにより前方へ引っ張られるようになる。このため、フットレストプレート11は、その第一ワイヤー連結部11bをワイヤー15bによって前方に引っ張られることにより、フットレストプレート取付部12aに対して相対的に前方へとスライドする。フットレストプレート11の迫出量ΔLは、動滑車15aのスライド量X(第一リンク12bの先端部のスライド量)の2倍になる。したがって、第二実施態様のオットマン装置10は、第一実施態様のオットマン装置10と比較して、迫出量ΔLを約2倍とすることが可能となっている。第二実施態様のオットマン装置10におけるその他の構成については、第一実施態様のオットマン装置10と同様であるために、説明を割愛する。 In this way, by connecting the distal end portion of the first link 12b to the footrest plate 11 via the movable pulley 15a and the wire 15b, when the distal end portion of the first link 12b moves forward along with the deployment operation, The pulley 15a also moves forward, and the wire 15b wound around the pulley 15a is pulled forward by the moving pulley 15a. For this reason, the footrest plate 11 is slid forward relative to the footrest plate mounting portion 12a by pulling the first wire connecting portion 11b forward by the wire 15b. The amount of protrusion ΔL of the footrest plate 11 is twice the slide amount X of the movable pulley 15a (the slide amount of the tip portion of the first link 12b). Therefore, the ottoman device 10 of the second embodiment can make the amount of squeezing ΔL about twice that of the ottoman device 10 of the first embodiment. About the other structure in the ottoman apparatus 10 of a 2nd embodiment, since it is the same as that of the ottoman apparatus 10 of a 1st embodiment, description is omitted.
3.第三実施態様のオットマン装置
 続いて、第三実施態様のオットマン装置について説明する。図6は、第三実施態様のオットマン装置10におけるフットレストプレート11の周辺を拡大して示した側面図である。第三実施態様のオットマン装置10は、図6に示すように、その連動迫出機構13として、フットレストプレート11の前端部に回動可能に設けられた可動部11cを上方に回動させることによりフットレストプレート11を実質的に迫り出させ、可動部11cを下方に回動させることによりフットレストプレート11を実質的に後退させる跳上げ機構を利用したものとなっている。
3. Next, the ottoman device of the third embodiment will be described. FIG. 6 is an enlarged side view showing the periphery of the footrest plate 11 in the ottoman device 10 of the third embodiment. As shown in FIG. 6, the ottoman device 10 according to the third embodiment, as the interlocking ejection mechanism 13, rotates a movable portion 11 c provided rotatably at the front end portion of the footrest plate 11 upward. The footrest plate 11 is substantially pushed out and a movable mechanism 11c is rotated downward to utilize a jumping mechanism that substantially retracts the footrest plate 11.
 第三実施態様のオットマン装置10においては、可動部11cと四点リンク機構12を連結部材16を介して連結することにより実現している。連結部材16の基端部は、第一リンク12bの先端部に連結され(図6の点Q)、連結部材16の先端部は、可動部11cの基端側に下向きに設けたアーム部11dの先端部に連結されている(図6の点R)。可動部11cは、その基端部をフットレストプレート11の本体部に対して回動可能な状態で連結されている(図6の点R)。このため、展開動作に伴って第一リンク12bの先端部が前方へ移動すると、連結部材16がアーム部11dを下向きに押すことにより、可動部11cが前方へ迫り出した状態となるようになっている。第三実施態様のオットマン装置10におけるその他の構成については、第一実施態様又は第二実施態様のオットマン装置10と同様であるために、説明を割愛する。 In the ottoman device 10 of the third embodiment, this is realized by connecting the movable portion 11 c and the four-point link mechanism 12 via the connecting member 16. The proximal end portion of the connecting member 16 is connected to the distal end portion of the first link 12b (point Q 1 in FIG. 6), and the distal end portion of the connecting member 16 is an arm portion provided downward on the proximal end side of the movable portion 11c. It is connected to the tip of 11d (point R 2 in FIG. 6). The movable part 11c is connected so that the base end part can be rotated with respect to the main body part of the footrest plate 11 (point R 1 in FIG. 6). For this reason, when the front-end | tip part of the 1st link 12b moves ahead with expansion | deployment operation | movement, when the connection member 16 pushes the arm part 11d downward, the movable part 11c will be in the state which protruded ahead. ing. Since the other configurations of the ottoman device 10 of the third embodiment are the same as those of the ottoman device 10 of the first embodiment or the second embodiment, description thereof is omitted.
4.第四実施態様のオットマン装置
 続いて、第四実施態様のオットマン装置について説明する。図7は、第四実施態様のオットマン装置10におけるフットレストプレート11の周辺を拡大して示した側面図である。第四実施態様のオットマン装置10は、図7に示すように、迫り出し状態にあるフットレストプレート11の角度を調節するための角度調節機構17を備えたものとなっている。この角度調節機構17は、図示省略の角度調節操作手段(操作レバーやハンドルなど)によって操作することができるようになっている。角度調節手段は、通常、フットレストプレート11の側方か、操作ワイヤーなどを介して座席脇などに設けられる。
4). Next, the ottoman device of the fourth embodiment will be described. FIG. 7 is an enlarged side view showing the periphery of the footrest plate 11 in the ottoman device 10 of the fourth embodiment. As shown in FIG. 7, the ottoman device 10 according to the fourth embodiment includes an angle adjustment mechanism 17 for adjusting the angle of the footrest plate 11 in the protruding state. The angle adjustment mechanism 17 can be operated by angle adjustment operation means (operation lever, handle, etc.) (not shown). The angle adjusting means is usually provided on the side of the footrest plate 11 or on the side of the seat via an operation wire or the like.
 角度調節機構17の具体的な構造は特に限定されないが、第四実施態様のオットマン装置10においては、角度調節機構17を、フットレストプレート11の裏面側に配された支持基体17aと、基体17aの前端部(図7における点S)に回動可能な状態で取り付けられたカム17bとで構成している。フットレストプレート11は、その基端部を支持基体17aにおける基端部(図7における点S)に対して回動可能な状態で取り付けられている。フットレストプレート取付部12aは、支持基体17aに固定されている。このため、先端部が後方を向いて倒伏状態にあるカム17bを、角度調節操作手段によって操作して点S回りに起立させると、フットレストプレート11の前端部がカム17bによって押し上げられ、フットレストプレート11の角度が変化するようになっている。第四実施態様のオットマン装置10におけるその他の構成については、第一実施態様から第三実施態様のオットマン装置10と同様であるために、説明を割愛する。 Although the specific structure of the angle adjusting mechanism 17 is not particularly limited, in the ottoman device 10 of the fourth embodiment, the angle adjusting mechanism 17 is provided with a support base 17a disposed on the back side of the footrest plate 11, and a base 17a. the front end portion is constituted by a cam 17b mounted and in rotatable state (point S 1 in FIG. 7). The footrest plate 11 is attached so that its base end portion can be rotated with respect to the base end portion (point S 2 in FIG. 7) in the support base 17a. The footrest plate mounting portion 12a is fixed to the support base 17a. Therefore, the cam 17b of the tip portion is in the inclined state facing backward, when erecting the point S 1 around by operating the angle adjusting operation means, the front end of the footrest plate 11 is pushed up by the cam 17b, the footrest plates The angle of 11 changes. About the other structure in the ottoman apparatus 10 of a 4th embodiment, since it is the same as that of the ottoman apparatus 10 of a 1st embodiment to a 3rd embodiment, description is omitted.
5.第五実施態様のオットマン装置
 最後に、第五実施態様のオットマン装置について説明する。図8は、第五実施態様のオットマン装置10におけるフットレストプレート11の周辺を拡大して示した底面図である。第五実施態様のオットマン装置10では、図8に示すように、安全機構14aを、コイルバネ14aと、揺動部材14bとで構成している。コイルバネ14aの一端部は、フットレストプレート11の裏面側に設けられたバネ受け部11aに連結され、コイルバネ14aの他端部は、揺動部材14bの一端部に連結されている。揺動部材14bの他端部は、連結部材12hを介してフットレストプレート取付部12aに一体的に設けられた軸支部12iに軸支されており、揺動部材14bは、図8における点Tを中心として揺動することができるようになっている。フットレストプレート11は、その裏面側に固定された一対のスライドレール11eを介してフットレストプレート取付部12aに支持された状態となっており、フットレストプレート取付部12aに対して相対的に前後方向へスライドすることができるようになっている。
5. Finally, the ottoman device of the fifth embodiment will be described. FIG. 8 is an enlarged bottom view showing the periphery of the footrest plate 11 in the ottoman device 10 of the fifth embodiment. In the ottoman device 10 of the fifth embodiment, as shown in FIG. 8, the safety mechanism 14a includes a coil spring 14a and a swing member 14b. One end of the coil spring 14a is connected to a spring receiving portion 11a provided on the back side of the footrest plate 11, and the other end of the coil spring 14a is connected to one end of the swing member 14b. The other end of the swing member 14b is pivotally supported by a shaft support portion 12i provided integrally with the footrest plate mounting portion 12a via a connecting member 12h. The swing member 14b is a point T 1 in FIG. Can be swung around the center. The footrest plate 11 is supported by the footrest plate mounting portion 12a via a pair of slide rails 11e fixed to the back side thereof, and slides in the front-rear direction relative to the footrest plate mounting portion 12a. Can be done.
 この第五実施態様のオットマン装置10においては、第一実施態様のオットマン装置10と同様、通常時には、コイルスプリング14aによってフットレストプレート11が前方に迫り出した状態となっているものの、前方から異常負荷が掛かった際には、フットレストプレート11がコイルバネ14aの付勢力に抗って後退するようになっている。第五実施態様のオットマン装置10におけるその他の構成については、第一実施態様から第四実施態様のオットマン装置10と同様であるために、説明を割愛する。 In the ottoman device 10 of the fifth embodiment, as in the ottoman device 10 of the first embodiment, although the footrest plate 11 is normally pushed forward by the coil spring 14a, an abnormal load is applied from the front. When is applied, the footrest plate 11 is retracted against the urging force of the coil spring 14a. Other configurations of the ottoman device 10 of the fifth embodiment are the same as those of the ottoman device 10 of the first embodiment to the fourth embodiment, and thus description thereof is omitted.
