Abstract

PROBLEM TO BE SOLVED: To provide a simple and light-weight device without requiring a parallel moving mechanism in order to keep the bed surface horizontal, in a vertically moving type bed. SOLUTION: A double acting type hydraulic cylinder is used as the legs of a bed, and a piping connection is performed in such a manner that the piston moving amounts of the double acting type hydraulic cylinders may become equal. Thus, the vertical moving of the bed under a horizontal state is made possible.

Description

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【発明の属する技術分野】家庭用寝台あるいは医療用寝台に関するものである。 BACKGROUND OF THE INVENTION relates to a household bed or a medical bed.

【0002】 [0002]

【従来の技術】従来の昇降寝台においては、寝具面を水平に保ったまま平行に昇降させるための複雑なリンク機構を必要とした。 In conventional lifting bed required a complicated link mechanism for parallel lift while maintaining the bedding plane horizontally.

【0003】 [0003]

【発明が解決しようとする課題】従来の平行移動機構は寝具面下部に設置された大掛かりなものとなり重量も大きく、また寝台下部を収納部として利用することをさまたげるものであった。 Conventional parallel movement mechanism [0005] The weight becomes as large-scale installed in the bedding plane bottom is large, also were those which preclude the use of the bed bottom as a storage unit. 本発明はこれらの不具合を排除するために考案されたものである。 The present invention has been devised in order to eliminate these problems.

【0004】 [0004]

【課題を解決するための手段】本発明では、複動式油圧シリンダによって寝台の全ての脚を直接伸縮することによって寝台の構造を簡素化し、かつ等しい距離だけ伸縮するように油圧で連結したものである。 In the present invention, there is provided a means for solving], the concatenation hydraulically to simplify the structure of the bed by stretching directly all of the legs of the bed by the double acting hydraulic cylinder, and to a distance equal stretch it is. ひとつの油圧シリンダの下側油室を隣の油圧シリンダの上側油室へ接続し、同様に全てのシリンダを順次同様に接続することによって、全てのシリンダが等しい距離だけ伸縮するようにして、寝具面を水平に保つようにしたものである。 Connect the lower oil chamber of one of the hydraulic cylinder to the upper oil chamber next to the hydraulic cylinder, as well as by connecting all the cylinders sequentially Similarly, so as to stretch a distance all the cylinders are equal, bedding it is obtained to keep the surface horizontal. このように連結された複動式油圧シリンダによって、寝具面の水平移動が確保されるので、寝具面を上下させる動力は人力あるいは機械力であるかを問わない。 Such linked double acting hydraulic cylinder, since the horizontal movement of the bedding plane is secured, the power to lower the bedding plane does not matter whether it is manual or mechanical force.

【0005】 [0005]

【発明の実施の形態】実施例を図に基づいて説明する。 Will be described with reference to FIG embodiments PREFERRED EMBODIMENTS.
図1は寝台全体を示すものであり、4個の複動式油圧シリンダ11を寝台の脚として四隅に配置した状態を示す。 Figure 1 shows the entire bed, showing a state where the four double-acting hydraulic cylinder 11 arranged at the four corners as legs of the bed. ピストンロッド3が出入りして寝台の高さを調節する。 Piston rod 3 and out to adjust the height of the bed. なお図1においては油圧パイプ10の図示は省略されている。 Incidentally illustrated hydraulic pipe 10 in FIG. 1 are omitted. 図3にひとつの複動式油圧シリンダ11の断面図を示す。 It shows a cross-sectional view of one double-acting hydraulic cylinder 11 in FIG. 3. 上側油室5と下側油室6はそれぞれ等しい有効断面積を持ち、ピストン2がどの位置にあっても上側油室5と下側油室6の体積の和は一定である。 The upper oil chamber 5 and the lower oil chamber 6 has an effective area equal to each other, the sum of the volume of even the piston 2 is in which position the upper oil chamber 5 the lower oil chamber 6 is constant.

【0006】図2にこれら全ての複動式油圧シリンダ1 [0006] Figure 2 all of these double-acting hydraulic cylinders 1
1の接続状態を示す。 It shows one of the connection state. ひとつの複動式油圧シリンダ11 One of the double-acting hydraulic cylinder 11
の下側油室6と隣の複動式油圧シリンダ11の上側油室5とを油圧パイプ10によって接続し、順次同様に接続する。 An upper oil chamber 5 of the lower oil chamber 6 and the adjacent double-acting hydraulic cylinder 11 of the connecting by the hydraulic pipe 10, connected sequentially similarly. 油圧パイプ10によって連結された2つの油室内の体積の和は常に一定であるので、ひとつのピストンロッド3が移動すると全ての複動式油圧シリンダ11においてピストンロッド3はこれと同じ距離だけ移動する。 The sum of the two oil chambers of a volume which is connected by hydraulic lines 10 is always constant, the piston rod 3 in all double-acting hydraulic cylinder 11 when the one of the piston rod 3 moves to move the same distance as this .
このことによって、寝具面は常に水平を保持して昇降することが可能となる。 This allows the bedding plane is always possible to lift and hold the horizontal.

【0007】図4に油圧ポンプによって、昇降させる例を示す。 [0007] by the hydraulic pump in FIG. 4, showing an example in which the lift is.

【0008】 [0008]

【発明の効果】平行移動機構を必要としないため構造が簡単となり、軽量化できる。 Effects of the Invention translation mechanism structure is simple because it does not require, be lightweight. ベッドの下の空間が利用できる。 The space under the bed can be utilized.
