【０００１】
【発明の属する技術分野】
本発明は、ベッドのボトム上方に跨ぐようにもたらして使う、脚部折り畳み機能を有するテーブル装置に関し、特に、部品点数も減らして組み立て工程も容易とした、脚部折り畳み機能を有するテーブル装置に関するものである。
【０００２】
【従来の技術】
従来より、病院においても家庭内においても、ベッドのボトム上方に跨ぐようにもたらして使う、オーバーベッドテーブルがある。
かかるオーバーベッドテーブルとしては、特開平７−２６５１３４号公報で開示されるような折り畳み機能を備えたものが提案されている。
すなわちこのオーバーベッドテーブルでは、左右一対の伸縮脚の折り畳み中心軸と、前記一対の伸縮脚を同期的に伸縮させる機構である、線条体を掛け渡してなる上側滑車の回転中心軸とを別々に構成して、伸縮脚の折り畳みに伴って、前記線条体が緩むように、折り畳み中心軸を前記上側滑車の回転中心軸より水平方向内側に配置するようにしている。
【０００３】
【発明が解決しようとする課題】
このように、上記オーバーベッドテーブルの伸縮脚の折り畳み構造では、双方の伸縮脚を同期的に伸縮させる機構を構成する線条体が緩むように上側滑車の回転軸より内側に折り畳み軸を別個に設けたことで部品点数が多く、加工工程数も増加する結果となっている。
本発明は、このような不都合を改善するために提案されたものであって、脚部をより簡敏な折り畳み機構とし、部品点数も減らして組み立て工程も容易とした、脚部折り畳み機能を有するテーブル装置を提供することを目的とする。
【０００４】
【課題を解決するための手段】
前記した課題を解決するために、本発明では、請求項１において、一対の脚部により、テーブル板受具を介してテーブル板を支持してなり、前記テーブル板受具の両側箇所に、テーブル板受具中央に指向して下降傾斜させるように傾斜長穴を設けて、この傾斜長穴に移動可能に挿通した支軸を中心として前記脚部を折り畳み可能に構成し、前記脚部は、それぞれ第１の脚杆に対して第２の脚杆を進退可能に構成して、前記第２脚杆を同期的に昇降させる昇降同期手段を具備し、この昇降同期手段は、前記脚部における折り畳み中心軸である支軸を回転軸とする上部プーリと前記第２脚杆下端側内面に軸着した下部プーリとこれら上部プーリ下部プーリ間に線状部材を掛け渡して、この線状部材を前記第１脚杆側に固定する構成とした脚部折り畳み機能を有するテーブル装置を提案する。
また本発明では、請求項２において、前記脚部における第１脚杆内に昇降動作を拘束したり拘束解除する昇降補助手段を設け、この昇降補助手段の拘束作用を解除する解除操作手段を、前記昇降補助手段を配置した脚部側と、前記昇降補助手段を配置しない脚部側に配置し、これら双方の解除操作手段を、前記支軸を回転軸とするガイドプーリを介して掛け渡した線状部材により互いに連結する構成とした脚部折り畳み機能を有するテーブル装置を提案する。
さらに本発明では、請求項３において、前記脚部における第１脚杆内に昇降動作を拘束したり拘束解除する昇降補助手段を設け、この昇降補助手段の拘束作用を解除する解除操作手段を、前記昇降補助手段を配置した脚部側と、前記昇降補助手段を配置しない脚部側に配置し、前記昇降補助手段を配置した脚部側の解除操作手段に、直接前記昇降補助手段に作用する拘束解除作動部材を同軸的に配置して、前記昇降補助手段を設けた脚部側の解除操作手段を操作することで、この拘束解除作動部材を連動させて昇降補助手段の拘束解除を行なう構成とする一方、前記拘束解除作動部材を、前記昇降補助手段を配置しない脚部側の解除操作手段によって操作可能とするべく、この解除操作手段と、前記脚部の折り畳み中心軸としての支軸に配置したガイドプーリを介し、線状部材により連結する脚部折り畳み機能を有するテーブル装置を提案する。
【０００５】
請求項１によれば、一対の脚部を互いに折り畳んでいくと、脚部は、テーブル板受具の両側箇所に、テーブル板受具中央に指向して傾斜させるように設けた傾斜長穴に沿って支軸が移動しながらこの支軸を中心として倒伏し、前記脚部を折り畳むことができる。
前記支軸は、昇降同期手段を構成する上部プーリの上部プーリの回転軸を兼ねておりそれだけ部品点数を減らすことができる。
また、脚部を折り畳んでいくことにより、前記支軸は傾斜長穴に沿ってテーブル板受具中央に指向して移動するので、上部プーリ、下部プーリ間に掛け渡された線状部材は緩むが、その分、前記上部プーリに線状部材が巻き取られることで線状部材の緩みを解消することができる。
【０００６】
請求項２によれば、脚部における折り畳み中心軸である支軸は、脚部の昇降補助手段を、双方の昇降補助手段により連動操作可能とするための、伝達手段である線状部材のガイドプーリの回転中心軸を兼ねたことにより、それだけ部品点数を減らすことができる。
【０００７】
請求項３によれば、脚部における折り畳み中心軸である支軸は、脚部の昇降補助手段を、昇降補助手段を配置しない脚部側に配置した解除操作手段により操作可能とするための、伝達手段である線状部材のガイドプーリの回転中心軸を兼ねたことにより、それだけ部品点数を減らすことができる。
【０００８】
【発明の実施の形態】
次に、本発明にかかる脚部折り畳み機能を有するテーブル装置について、一つの実施の形態を示し、添付の図面に基づいて以下説明する。
図１に脚部折り畳み機能を有するテーブル装置１を示し、この脚部折り畳み機能を有するテーブル装置１は、一対の脚部２，２によってテーブル板受具３を介してテーブル板４を支持すると共に、前記テーブル板受具３に設けた傾斜長穴５，５に移動可能に挿通した支軸６，６を中心としてそれぞれ折り畳み可能に構成している。
【０００９】
前記一対の脚部２，２は、基端側にキャスタＣを介して床面に接地する基部フレーム７を取り付けた第１の脚杆８に対して第２の脚杆９を、昇降ガイドユニット（図示省略）を介して進退自在に構成している。
また、前記一対の脚部２，２は、昇降同期手段１０によって、それぞれ第１脚杆８に対して第２脚杆９を同期的に昇降させる構成としている（図２参照）。
さらにかかる一対の脚部２，２の片方、すなわち第１脚杆８内には第１脚杆８に対して第２脚杆９を所望の位置において拘束したり、拘束解除して自由に昇降させるようにした昇降補助手段１１を内蔵し、前記テーブル板４の両側テーブル板受具３に、前記昇降補助手段１１を拘束解除操作するための解除操作手段１２をそれぞれ配置している。
【００１０】
前記昇降同期手段１０は、前記第２脚杆９下端側内面に軸着した下部プーリ１３，１３と、脚部２，２の折り畳み中心軸としての支軸６，６に設けた上部プーリ１４，１４と、これら上部プーリ１４，１４および下部プーリ１３，１３間に掛け渡した線状部材１５とを備え、この線状部材１５を前記第１脚杆８側に固定した構成としている。
【００１１】
また前記昇降補助手段１１としては、ここではガススプリングを用いている。すなわち昇降補助手段１１は、前記第１脚杆８内に固設したガス封入シリンダ１６を有し、このシリンダ１６にガス圧によって支持されると共に、シリンダ１６から緩衝的に進退可能に突出するピストンロッド１７を有する。このピストンロッド１７先端部には、ピストンロッド１７を拘束／拘束解除するためのロック手段を構成する操作軸１８を突出させている（図３参照）。
【００１２】
また前記テーブル板４の両側テーブル板受具３に設けた双方の解除操作手段１２のうち、昇降補助手段１１を設けた脚部２側の解除操作手段１２には、直接前記昇降補助手段１１における操作軸１８を押し込む拘束解除作動部材１９を同軸的に配置して、前記昇降補助手段１１を設けた脚部２側の解除操作手段１２を操作することで、この拘束解除作動部材１９を連動させて昇降補助手段１１における操作軸１８を押し込んでロック解除を行なうようにしている。かかる拘束解除作動部材１９は、前記昇降補助手段１１を設けていない脚部２側の解除操作手段１２によって操作できるようにするために、この解除操作手段１２と、前記脚部２，２の折り畳み中心軸としての支軸６，６に配置したガイドプーリ２０，２０を介し、線状部材１５により連結している。
【００１３】
そして、前記テーブル板受具３に設けた傾斜長穴５，５は、前記テーブル板受具３の両側箇所に、テーブル板受具３中央に指向して下降傾斜させるように形成している。
【００１４】
以上のように脚部折り畳み機能を有するテーブル装置１は構成されるので、テーブル装置１の使用に際し、使用者はベッドにおけるボトムの高さにテーブル板４の高さを、昇降補助手段１１を双方の解除操作手段１２のうち、いずれかの解除操作手段１２により解除操作して、第２脚杆９を上げ下げして合わせることができる。
すなわち前記解除操作手段１２を操作すると、ピストンロッド１７の操作軸１８を押し込むので、ピストンロッド１７の拘束状態が解除され、第１脚杆８に対し第２脚杆９を自由に昇降させる状態とすることができる。このとき、一対の脚部２，２は、昇降同期手段１０によって、第２脚杆９を同期的に昇降させることができ、テーブル板受具３を介してテーブル板４を上下降させていくことができる。
このようにしてテーブル板４が所望の高さに至ったら、解除操作手段１２から手を離せば、解除操作手段１２がピストンロッド１７の操作軸１８から離脱するので、ピストンロッド１７は再び拘束状態となり、テーブル板４をその調節した位置で保持することができる。
【００１５】
そして、前記テーブル装置１を使用しないときは、そのままベッド傍らへ寄せて置いておくことができる。また、長期にわたり使用しないときは、一対の脚部２，２を折り畳んで倉庫等に保管することができる。
先ず、解除操作手段１２を操作して、前記一対の脚部２，２を下降させ、前記テーブル板４の高さを最低高さとする（図３参照）。
次いでテーブル装置１をひっくり返し、前記テーブル板４の上面を床面に着け、脚部２，２を上方へ向ける。
そして、一対の脚部２，２をそれぞれテーブル板受具３中央に指向して互いに折り畳むようにする。
すると、前記脚部２，２は、第１脚杆８頂部を取り付けた支軸６，６を中心として回転していき、前記支軸６，６は、テーブル板受具３中央に指向するように形成した傾斜長穴５，５に沿って移動し、折り畳んでいくことができる（図５参照）。
【００１６】
前記支軸６，６が、傾斜長穴５，５に沿って移動するに連れ、支軸６，６に取り付けられた昇降同期手段１０を構成する上部プーリ１４，１４も移動する。
すなわち、上部プーリ１４，１４は、テーブル板受具３中央に向かって傾斜長穴５，５に沿って移動した分、上部プーリ１４，１４に掛け渡された線状部材１５が緩むこととなるが、脚部２，２が折り畳まれていくことにより、前記線状部材１５は、上部プーリ１４，１４に巻き込まれていき、結果的に前記緩みが相殺される（図６参照）。
同様に、双方の解除操作手段１２間のガイドプーリ２０，２０も、前記支軸６，６と共に移動し、これらガイドプーリ２０，２０間に掛け渡された線状部材１５も緩むが、双方の解除操作手段１２と、拘束解除作動部材１９とは、テーブル板受具３側に折り畳まれる脚部２，２と共に、移動するので、緩みが吸収される。従って、脚部２，２を折り畳むことによって昇降同期手段１０の線状部材１５上部プーリ１４，１４から、また双方の解除操作手段１２間の線状部材１５がガイドプーリ２０，２０から外れるなどのトラブルは起こることはない。
【００１７】
以上のように、脚部２，２の折り畳み軸と昇降同期手段１０を構成する上部プーリ１４，１４、並びに双方の解除操作手段１２間のガイドプーリ２０，２０の回転軸心とを兼ねたことで、部品点数を減らすことができ、その分、製造加工工程も軽減することができる。
【００１８】
【発明の効果】
本発明によれば、
脚部を折り畳み可能な昇降調節脚自体の機構、より簡敏な折り畳み機構とし、部品点数も減らして組み立て工程も容易とすることができる。

Further, the pair of leg portions 2 and 2 are configured to raise and lower the second leg rod 9 synchronously with respect to the first leg rod 8 by the raising and lowering synchronization means 10 (see FIG. 2).
Further, one of the pair of leg portions 2 and 2, that is, in the first leg rod 8, the second leg rod 9 is restrained at a desired position with respect to the first leg rod 8, and is freely lifted by releasing the restraint. The raising / lowering assisting means 11 is built-in, and the release operation means 12 for releasing the restraint of the raising / lowering assisting means 11 is disposed on the both side table plate holders 3 of the table plate 4.
[ 0010 ]
The elevating / lowering synchronizing means 10 includes lower pulleys 13 and 13 pivotally attached to the inner surface of the lower end of the second leg rod 9 and upper pulleys 14 and 6 provided on support shafts 6 and 6 as folding central axes of the leg portions 2 and 2. 14 and a linear member 15 spanned between the upper pulleys 14 and 14 and the lower pulleys 13 and 13, and the linear member 15 is fixed to the first leg rod 8 side.
[ 0011 ]
As the raising / lowering assisting means 11, a gas spring is used here. That is, the lifting / lowering assisting means 11 has a gas-filled cylinder 16 fixed in the first leg rod 8 and is supported by the gas pressure by the cylinder 16 and protrudes from the cylinder 16 so as to be able to move forward and backward. It has a rod 17. An operation shaft 18 that constitutes a locking means for restraining / releasing the piston rod 17 is projected from the tip of the piston rod 17 (see FIG. 3).
[ 0012 ]
Of the two release operation means 12 provided on the table plate holders 3 on both sides of the table plate 4, the release operation means 12 on the leg 2 side provided with the lift support means 11 is directly connected to the lift support means 11. A restraint releasing operation member 19 for pushing the operating shaft 18 is arranged coaxially, and the release operating means 12 on the leg 2 side provided with the lifting / lowering assisting means 11 is operated to interlock the restraint releasing operating member 19. Thus, the operation shaft 18 in the lifting assist means 11 is pushed in to release the lock. The restraint release actuating member 19 can be operated by the release operation means 12 on the leg 2 side not provided with the lifting assist means 11 and the release operation means 12 and the legs 2 and 2 are folded. They are connected by a linear member 15 via guide pulleys 20 and 20 arranged on support shafts 6 and 6 as central axes.

At this time, the pair of leg portions 2 and 2 can raise and lower the second leg rod 9 synchronously by the raising and lowering synchronization means 10 and raise and lower the table plate 4 via the table plate holder 3. be able to.
When the table plate 4 reaches the desired height in this way, when the release operation means 12 is released, the release operation means 12 is detached from the operating shaft 18 of the piston rod 17, so that the piston rod 17 is again restrained. Thus, the table plate 4 can be held at the adjusted position.
[ 0015 ]
And when the said table apparatus 1 is not used, it can be put near the bed as it is. When not used for a long period of time, the pair of legs 2 and 2 can be folded and stored in a warehouse or the like.
First, the release operation means 12 is operated to lower the pair of legs 2 and 2 so that the height of the table plate 4 is set to the minimum height (see FIG. 3).
Next, the table device 1 is turned over, the upper surface of the table plate 4 is put on the floor surface, and the legs 2 and 2 are directed upward.
Then, the pair of leg portions 2 and 2 are respectively folded toward each other toward the center of the table plate holder 3.
Then, the leg portions 2 and 2 rotate around the support shafts 6 and 6 to which the tops of the first leg rods 8 are attached, and the support shafts 6 and 6 are directed toward the center of the table plate holder 3. It can move along the slanted long holes 5 and 5 formed in, and can be folded (refer FIG. 5).
[ 0016 ]
As the support shafts 6, 6 move along the inclined elongated holes 5, 5, the upper pulleys 14, 14 constituting the lift synchronization means 10 attached to the support shafts 6, 6 also move.
That is, as the upper pulleys 14 and 14 move along the inclined elongated holes 5 and 5 toward the center of the table plate holder 3, the linear member 15 spanned over the upper pulleys 14 and 14 is loosened. However, when the leg portions 2 and 2 are folded, the linear member 15 is wound around the upper pulleys 14 and 14, and as a result, the loosening is offset (see FIG. 6).
Similarly, the guide pulleys 20 and 20 between the two release operation means 12 also move together with the support shafts 6 and 6, and the linear member 15 stretched between the guide pulleys 20 and 20 also loosens. Since the release operation means 12 and the restraint release operation member 19 move together with the leg portions 2 and 2 folded to the table plate holder 3 side, the looseness is absorbed. Therefore, by folding the legs 2 and 2, the linear member 15 of the lifting / lowering synchronizing means 10 is disengaged from the upper pulleys 14 and 14, and the linear member 15 between the two release operating means 12 is disengaged from the guide pulleys 20 and 20. Trouble never happens.
[ 0017 ]
As described above, both the folding shafts of the legs 2 and 2 and the upper pulleys 14 and 14 constituting the elevating and synchronizing means 10 and the rotational axis of the guide pulleys 20 and 20 between the release operation means 12 are used. Thus, the number of parts can be reduced, and the manufacturing process can be reduced accordingly.
