Description

本発明は、乳児を寝かせるベッドを、モーターで上下動させる乳児用ベッドに関する。   The present invention relates to an infant bed in which a bed for laying an infant is moved up and down by a motor.

乳児を寝かせるベッドを手動で上下動させるものが存在する。これは、揺り籠状のベッドをベッドフレーム内に収容すると共に、ベッドをスプリングでベッドフレームから吊り下げたものである。そして、ベッドを上から押さえて手を離すと、スプリングの弾力と、ベッド及び乳児の重みによってベッドが上下動を繰り返し、その上下動によって乳児に眠気をもたらす。
特願２００３−０７５３４１ There are those that manually move the bed that lays an infant up and down. In this method, a rocking bed is accommodated in the bed frame, and the bed is suspended from the bed frame by a spring. Then, when the bed is pressed from the top and released, the bed repeats vertical movement by the elasticity of the spring and the weight of the bed and the baby, and the vertical movement brings sleepiness to the baby.
Japanese Patent Application No. 2003-075341

ところが、これはスプリングでベッドを吊り下げたものなので、例えば乳児の上の子供等が非常に強い力でベッドを上から押さえて手を離すと、深く沈んだ分だけストロークの長い上下動が予想外の激しい勢いで繰り返されることになり、安全上好ましくない。また、上下動は徐々に弱まっていくので、乳児が寝付くまで、ベッドを押さえて手を離す作業を続けなければならず、煩雑である。   However, since this is a spring-suspended bed, for example, if a child on an infant presses the bed from the top with a very strong force and releases his hand, it is expected to move up and down with a long stroke by the amount of deep sinking It will be repeated with a strong external force, which is not preferable for safety. Moreover, since the vertical movement gradually weakens, it is necessary to continue the work of pressing the bed and releasing the hand until the baby falls to sleep, which is complicated.

本発明は上記実情を考慮してなされたもので、その目的は、乳児を寝かすベッドを自動的に上下動でき、しかも、想定外の力を加えても上下動の速度を殆ど一定に保持することである。   The present invention has been made in consideration of the above circumstances, and its purpose is to automatically move the bed that lays an infant up and down, and to keep the speed of vertical movement almost constant even when an unexpected force is applied. That is.

本発明の乳児用ベッドは、土台の上にベッド載置台を載せ、昇降用のガイドとガイドに通す鉛直なポストのうち一方を土台に、他方をベッド載置台に設け、土台に止めたモーターの水平な出力軸にアームを介してローラーを偏心位置に固定し、ローラーが押し上げる支持バーをベッド載置台に設け、出力軸を中心にして公転するローラーの上下動によってベッド載置台を昇降させることを特徴とする。   The baby bed according to the present invention is a motor that is mounted on a base, on which a bed mounting table is placed, and one of a lifting post and a vertical post passing through the guide is provided on the base, and the other is provided on the bed mounting table. A roller is fixed to an eccentric position via an arm on a horizontal output shaft, a support bar that the roller pushes up is provided on the bed mounting table, and the bed mounting table is moved up and down by the vertical movement of the roller revolving around the output shaft. Features.

下降から上昇に転ずる際にベッド載置台及びその上のベッドに寝かせた乳児に衝撃が加わるが、公転するローラーの下降時にはベッド載置台等の重みによってモーターが早く回転してその衝撃力が強まる。これを防ぎつつベッド載置台を昇降させるには、請求項２の発明のように、ベッド載置台を押し上げる衝撃吸収手段を、土台とベッド載置台の間に連結すると共に、衝撃吸収手段の押し上げ力に反してベッド載置台を下方に引き寄せるために、公転時のローラーを平面視した軌跡を囲む案内枠を支持バーに設け、案内枠内にローラーを収容することが望ましい。このようにすれば、衝撃吸収手段によってベッド載置台に押し上げ力が加わっていても、案内枠によってベッド載置台を下方に引き寄せることができる。   When falling from rising to rising, an impact is applied to the bed table and the infant laid on the bed, but when the revolving roller descends, the motor rotates faster due to the weight of the bed table and the impact force is strengthened. In order to raise and lower the bed mounting table while preventing this, the shock absorbing means for pushing up the bed mounting table is connected between the base and the bed mounting table as in the invention of claim 2 and the pushing force of the shock absorbing means is increased. On the other hand, in order to pull the bed mounting table downward, it is desirable to provide a guide frame surrounding the trajectory of the roller during revolution in plan view on the support bar and accommodate the roller in the guide frame. If it does in this way, even if the pushing-up force is added to the bed mounting base by the impact absorbing means, the bed mounting base can be pulled downward by the guide frame.

請求項１の発明は、公転するローラーの上下動によってベッド載置台を昇降するものなので、ベッド載置台の昇降速度は一定に保たれ安全である。また、モーターで昇降させるものなので、乳児が寝付くまで人手を介さずとも昇降を繰り返すことができ、都合がよい。   Since the bed mounting table is moved up and down by the vertical movement of the revolving roller, the lifting speed of the bed mounting table is kept constant and safe. Moreover, since it is moved up and down by a motor, it can be raised and lowered repeatedly without human intervention until the baby falls to sleep.

請求項２の発明は、案内枠にローラーを収容してあるので、衝撃吸収手段の押し上げ力に反してベッド載置台等を下降させることができる。そして、ローラー下降時にベッド載置台等の重みによってモーターが勢いよく回転して下降速度が早まるのを、衝撃吸収手段で遅くするので、下降から上昇に転ずる際に乳児にかかる衝撃を弱めることができる。   In the invention of claim 2, since the roller is accommodated in the guide frame, the bed mounting table and the like can be lowered against the push-up force of the impact absorbing means. And, when the roller descends, the weight of the bed mounting table etc. makes the motor rotate vigorously and the descending speed is accelerated by the impact absorbing means, so that the impact on the baby can be weakened when turning from descending to rising .

本発明の乳児用ベッドは図１から図３に示すように、床上に設置する土台１に対してベッド載置台２を自動的に昇降可能に設けると共に、土台１とベッド載置台２の間に昇降時の衝撃吸収手段３を介在したものである。   As shown in FIGS. 1 to 3, the baby bed of the present invention is provided with a bed mounting table 2 that can be automatically raised and lowered with respect to a base 1 installed on the floor, and between the base 1 and the bed mounting table 2. The shock absorbing means 3 at the time of raising and lowering is interposed.

土台１は、縦横の桟４を矩形状に枠組し、枠の四隅の底側にキャスター５を付け、枠の上側にはスライドポスト６を前後左右に間隔をあけて起立してある。枠内のほぼ中央部には受け桟７を架設し、受け桟７の上にモーター８を止めてある。モーター８の水平な出力軸９に鉛直なアーム１０を介してローラー１１を水平に止め、出力軸９に対してローラー１１を偏心位置とし、モーター８の駆動によって出力軸９を中心にしてローラー１１が公転する。受け桟７の側方であって枠の内側ほぼ中央部には下桟１２を架設し、下桟１２の前後幅中央部にブラケット１３を介して衝撃吸収手段３の下端部を止めてある。衝撃吸収手段３を設けたのは、公転に伴うローラー１１の下降時にはベッド載置台２等の重みによってモーター８が早く回転するので、これを防ぐためである。   The base 1 is a frame in which vertical and horizontal bars 4 are formed in a rectangular shape, casters 5 are attached to the bottom sides of the four corners of the frame, and slide posts 6 are erected on the upper side of the frame at intervals in the front, rear, left, and right directions. A receiving bar 7 is installed at a substantially central portion in the frame, and a motor 8 is stopped on the receiving bar 7. The roller 11 is stopped horizontally via the vertical arm 10 on the horizontal output shaft 9 of the motor 8, the roller 11 is set in an eccentric position with respect to the output shaft 9, and the roller 11 is centered on the output shaft 9 by driving the motor 8. Revolves around. A lower beam 12 is installed on the side of the receiving beam 7 and substantially at the center inside the frame, and a lower end portion of the shock absorbing means 3 is stopped via a bracket 13 at a central portion in the front and rear width of the lower beam 12. The reason for providing the shock absorbing means 3 is to prevent the motor 8 from rotating faster due to the weight of the bed table 2 or the like when the roller 11 descends due to revolution.

衝撃吸収手段３は、シリンダに対してピストンロッドが往復動可能なダンパ（高圧ガス封入ダンパ）であって、図面上はシリンダ側を土台１に止め、ピストンロッド側をベッド載置台２に止め、その弾性力によってベッド載置台２を押し上げる力が加わっている。   The shock absorbing means 3 is a damper (high-pressure gas-filled damper) in which the piston rod can reciprocate with respect to the cylinder. In the drawing, the cylinder side is fixed to the base 1, and the piston rod side is fixed to the bed mounting table 2. A force for pushing up the bed mounting table 2 is applied by the elastic force.

ベッド載置台２は、縦横の桟１４を矩形の箱形に骨組してフレーム１５を形成し、フレーム１５内の上側には上桟１６を、下桟１２の真上に架設し、上桟１６にブラケット１７を介して衝撃吸収手段３のピストンロッド側を止めてある。また、スライドポスト６を通して上下に案内する筒状のガイド（ベアリング）１８をフレーム１５の下側に前後左右に間隔をあけて固定してある。前述したローラー１１の公転時の軌跡を平面視すると直線往復運動となり、その直線往復軌跡に沿って、ローラー１１が支える支持バー１９をフレーム１５の下側中央部に架設してある。   In the bed mounting table 2, a frame 15 is formed by framing vertical and horizontal bars 14 into a rectangular box shape, an upper bar 16 is installed on the upper side of the frame 15, and the upper bar 16 is installed directly above the lower bar 12. The piston rod side of the impact absorbing means 3 is stopped via a bracket 17. Further, a cylindrical guide (bearing) 18 that is guided up and down through the slide post 6 is fixed to the lower side of the frame 15 with a space in the front, rear, left and right directions. When the trajectory at the time of revolution of the roller 11 is viewed in plan, it becomes a linear reciprocating motion, and a support bar 19 supported by the roller 11 is installed in the lower center portion of the frame 15 along the linear reciprocating trajectory.

ローラー１１が公転して下方に向かう際に前述した衝撃吸収手段３の上向きの力によってローラー１１から支持バー１９が離れてベッド載置台２が常時上に位置するのを防ぐには、衝撃吸収手段３の押し上げ力に反してベッド載置台２を下方に引き寄せる必要がある。そのために、公転時のローラー１１の直線往復軌跡を上下前後から囲む案内枠２０を、支持バー１９の下に形成する。支持バー１９自体が案内枠２０の一部となっており、案内枠２０内にローラー１１を上下に回転用の遊びのある状態で収容してある。従って、公転に伴うローラー１１の下降時に案内枠２０が押し込まれて、ベッド載置台２が追従して下降する。案内枠２０を組んだ後ではローラー１１を収容できないので、支持バー１９の底面にローラー１１を当てた状態で残りのコ字部分を組んで案内枠２０を形成することによって、案内枠２０内にローラー１１を収容する。   In order to prevent the support bar 19 from being separated from the roller 11 by the upward force of the impact absorbing means 3 described above when the roller 11 revolves and moves downward, the shock absorbing means is prevented from being always positioned on the bed 11. It is necessary to pull the bed mounting table 2 downward against the pushing force of 3. For this purpose, a guide frame 20 that surrounds the linear reciprocating locus of the roller 11 during revolution from above and below is formed under the support bar 19. The support bar 19 itself is a part of the guide frame 20, and the roller 11 is accommodated in the guide frame 20 with a play for rotation up and down. Accordingly, the guide frame 20 is pushed when the roller 11 is lowered due to the revolution, and the bed mounting table 2 is lowered following. Since the roller 11 cannot be accommodated after the guide frame 20 is assembled, the guide frame 20 is formed by assembling the remaining U-shaped portions in a state where the roller 11 is applied to the bottom surface of the support bar 19. The roller 11 is accommodated.

図２，図３に示すようにフレーム１５の上側には持ち手２１を側方に突出しており、持ち運びを容易にしてある。土台１及びベッド載置台２は、組む材料の桟４，１４に中空形材を用いることによって軽量化を図ってある。なお、図示しないが、ベッド載置台２の周囲（前後左右）に防音板を張り巡らせれば、モーター８の駆動音が外部に漏れ難くなり、静かな製品になる。   As shown in FIGS. 2 and 3, a handle 21 protrudes laterally on the upper side of the frame 15 to facilitate carrying. The base 1 and the bed mounting table 2 are reduced in weight by using a hollow material for the crosspieces 4 and 14 of the material to be assembled. Although not shown, if a soundproof plate is stretched around the bed mounting table 2 (front / rear / left / right), the drive sound of the motor 8 is less likely to leak to the outside, resulting in a quiet product.

モーター８は、ｏｎ／ｏｆｆ用のスイッチと、タイマー機能を備えた制御部を有している（図示省略）。スイッチをｏｎすると、制御部がタイマー機能によって数分間モーター８を連続運転し、その後、強制的にモーター８の運転を停止する。従って、スイッチをｏｆｆし忘れても、数分後には上下動が停止するので、乳児に悪影響はない。   The motor 8 has an on / off switch and a control unit having a timer function (not shown). When the switch is turned on, the control unit continuously operates the motor 8 for several minutes by the timer function, and then forcibly stops the operation of the motor 8. Therefore, even if the switch is forgotten to be turned off, since the vertical movement stops after a few minutes, the infant is not adversely affected.

上述した乳児用ベッドは、ベッド載置台２の上に容器状のベッド２２を載せる。その後、ベッド２２の上に乳児を載せて、モーター駆動用のスイッチをｏｎすると、モーター８の出力軸９が回転し、それによってローラー１１が公転する。ガイド１８内にスライドポスト６を通してあるので、ローラー１１の公転に伴ってベッド載置台２が安定して昇降する。また、衝撃吸収手段３によってベッド載置台２を押し上げているので、ベッド載置台２がゆっくり下降する。一方、衝撃吸収手段３の押し上げ力とベッド載置台２等の重みによる下降力がほぼ釣り合って、ベッド載置台２がゆっくり上昇する。従って、公転時のローラー１１の上下動に伴って、乳児を寝かせたベッド２２がベッド載置台２と一緒にゆっくり上下動し、そのうちに乳児が寝付き、その後、タイマーによってベッド載置台２の上下動が自動的に停止する。符号２３は敷き布団である。   The baby bed described above places a container-like bed 22 on the bed mounting table 2. Thereafter, when an infant is placed on the bed 22 and the motor driving switch is turned on, the output shaft 9 of the motor 8 rotates, whereby the roller 11 revolves. Since the slide post 6 passes through the guide 18, the bed mounting table 2 moves up and down stably as the roller 11 revolves. Moreover, since the bed mounting table 2 is pushed up by the impact absorbing means 3, the bed mounting table 2 is slowly lowered. On the other hand, the push-up force of the impact absorbing means 3 and the descending force due to the weight of the bed table 2 and the like are substantially balanced, and the bed table 2 slowly rises. Accordingly, as the roller 11 moves up and down during revolution, the bed 22 on which the baby is laid slowly moves up and down together with the bed mounting table 2, and the baby falls to sleep, and then the bed mounting table 2 is moved up and down by a timer. Will automatically stop. Reference numeral 23 denotes a mattress.
