Description

  The present invention relates to a crib. Specifically, the present invention relates to a rocking baby bed.

  In recent years, the “declining birthrate” that disrupts economic activities and social security systems has become a serious problem in Japan. In order to solve such a declining birthrate, it is necessary to build a society where children can be born and raised with peace of mind, but raising parents, especially infants who cry at night, is a major burden for parents. Yes.

  Infants' sleep is particularly unstable until 3 months of age, and this time is said to be a time when it is easy to cry at night. In addition, as soon as I thought that the baby had fallen asleep after a long time, and started to cry like a fire, the fatigued days that parents could not sleep all night continued. And stress makes it difficult to concentrate on the care of the infant, creating a vicious circle that leads to further crying at night.

Therefore, in order to reduce the burden on the parent, various inventions have been proposed that shake the infant instead of the parent. For example, in Patent Document 1 relating to the baby bed shown in FIG. 6, the bed mounting table 102 is placed on the base 101, and one of the lifting guide 118 and the vertical slide post 106 passing through the guide is attached to the base 101. The other is provided on the bed mounting table 102, the roller 111 is fixed to an eccentric position via the arm 110 on the horizontal output shaft 109 of the motor 108 fixed to the base 101, and the support bar 119 pushed up by the roller 111 is attached to the bed mounting table 102. An infant bed is described in which the bed platform 102 is moved up and down by a vertical movement of a roller 111 that revolves around an output shaft 109. Further, a container-like bed 122 on which a mattress is laid is placed on the bed mounting table 102.
Further, in Patent Document 1, the motor 108 has an on / off switch and a control unit having a timer function. When the switch is turned on, the control unit continuously operates the motor 108 for several minutes by the timer function. After that, it is described that the operation of the motor 108 is forcibly stopped.

JP 2006-325666 A

  However, in the conventional baby bed, the motor was forcibly stopped and the swing was decelerated at a constant acceleration and stopped naturally. For example, if the acceleration is small so that the swing of the swing stops naturally, However, in the case of a mechanical product having a complicated mechanism using a motor or the like, the acceleration generally increases and stops immediately. Infants feel the rocking comfortably, and if this comfortable rocking suddenly stops, they will feel uncomfortable and cry immediately.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a crib that is less likely to cause discomfort to the user.

  In order to achieve the above object, the crib of the present invention is a crib provided with a floor board and a rocking means for rocking the floor board, and the rocking means is controlled to a predetermined pattern and then The swing of the floor board is stopped.

  Here, the swinging means can prevent sudden stoppage of the swinging by stopping the swinging of the floor board after controlling to a predetermined pattern.

  Further, in the crib of the present invention, when the predetermined pattern has a plurality of stages in which the rocking speed decreases with time, it is possible to make it difficult for the user to feel the rocking change.

Further, the crib of the present invention includes a sensor that senses the user's human body information and starts swinging by the swinging means, and the swinging period of the swinging means until a predetermined time elapses from the detection by the sensor. When the swinging period of the swinging means is shorter than the predetermined time, the change in the user's condition, for example, crying at night is detected and the swinging speed is increased immediately to stop crying and swinging. You can get a comfortable shaking by slowing down the speed.
The “user” here includes, for example, an infant who is a child who is less than one year old. The “human body information” here includes, for example, body temperature, body movement, and voice.

  Further, in the crib of the present invention, when the sensor is a sound sensor that senses a sound and starts swinging by the swinging means, for example, it can detect and swing an infant's cry and feel uncomfortable feelings. It is effective for infants expressing crying.

In the crib of the present invention, an enclosure member attached to the floor board to form a space above the floor board, an upper member slidably attached to the upper part of the enclosure member, and an opening formed in the enclosure member A flexible member that is attached and covers the opening and that can be seen through the inside, wherein at least one of the enclosure members is slidable in a substantially vertical direction, and at least one height of the enclosure member is equal to that of the other enclosure members. If it is lower than the height, it is attached to the opening formed in the enclosure member and covers the opening. Because it is possible, the mother can feel at ease from the outside to see the baby.
Moreover, since the height of at least one of the enclosure members is lower than the height of the other enclosure members, the infant can be easily placed on the bed or lowered from the bed from the lower enclosure member side.
In addition, since at least one of the enclosing members can slide in a substantially vertical direction, the encircling member can be slid in a substantially vertical downward direction so that the baby can be placed on the bed more easily or lowered from the bed.

  The crib according to the present invention is less likely to cause discomfort to the user.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to facilitate understanding of the present invention.
FIG. 1 is a schematic view for explaining a crib to which the present invention is applied. The crib 1 of the present invention is mounted on four sides of a floor board (not shown) that supports the body of a user, for example, an infant who is a child under one year of age, and above the floor board. An enclosure member 4 that forms a space, an upper member 5 that is slidably attached to the upper part of the enclosure member, and a front side that constitutes a front enclosure member among the enclosure members attached to the four sides and that can slide in a substantially vertical direction An enclosure member 6, a net (an example of a flexible member) 7 that is attached to and covers the opening formed in the enclosure member, and a mattress 8 laid on the floor board; The four wheels 9 and two of the four wheels are casters and send signals to a stopper 10 attached to the casters and a motor (not shown) that swings a floor board (not shown). Drive the motor (not shown) A touch panel controller 11, a storage body 12 that is located below a floor board (not shown) and stores a motor (not shown), and the like, and an emergency stop button 12A that urgently stops swinging in an emergency. . Further, the height of the front enclosure member 6 is lower than the height of the enclosure member 4 facing the front enclosure member 6.

  Here, the net is attached to the opening formed in the enclosure member, but the opening may not necessarily be formed and the net may be attached. For example, if the space on the floor plate is not sealed, the enclosure member itself May be made of a soft material.

  FIG. 2 is a schematic sectional view of a crib to which the present invention is applied. On the floor board 2, a snowboard 14 is placed, and a quilt 8 is laid thereon. Further, below the floor plate 2, a motor (an example of a swinging unit) that swings and stops swinging the floor plate 2 via the motor plate 3C, the rotation link 15, the swing roller 15A, and the swing plate 15B. 3), the inverter 3B, the cry sensor 16 for detecting the infant's cry, and the programmable controller 3A for appropriately processing signals from the cry sensor and the controller and issuing commands to the inverter to drive the motor. It is stored inside. In addition, a condenser microphone 13 is attached to the upper part of the enclosure member 4 and collects sounds such as a baby's cry.

  Here, the programmable controller 3A appropriately processes signals from the cry sensor 16 and the touch panel controller 11, and issues a command to the inverter 3B to drive the motor 3, but if the motor shaft rotates, The rotation link 15 directly connected rotates, and the swing roller 15A attached to the rotation link 15 pushes the swing plate 15B, whereby the force applied to the swing plate 15B swings the floor plate 2. . As the floor plate 2 swings, the enclosure member 4 also swings.

Next, a description will be given from the swing start to the swing stop.
First, when the condenser microphone 13 collects a sound larger than a predetermined value such as an infant's cry for 3 seconds, the cry sensor 16 judges the sound as a cry and senses it. Next, a signal is transmitted from the cry sensor 16 to the programmable controller 3A. Then, a command is issued from the programmable controller 3A to the inverter 3B, the motor 3 is driven, and the floor board 2 is swung.

For a predetermined time, for example, 30 seconds from the detection by the cry sensor 16, the rocking is performed at a speed that is two steps faster (a rocking cycle is shorter) than a preset speed. Then, when 30 seconds have passed since the detection by the cry sensor 16, the rocking is performed at a preset speed.
Here, when the cry sensor 16 detects a cry during swinging, the predetermined time is counted from the beginning. In other words, it swings again for 30 seconds with a two-stage speed increased. At this time, the preset swing time is also reset and timed from the beginning. That is, for example, if a cry is detected while swinging in advance with a swing time set for 15 minutes, the remaining swing time returns to 15 minutes, and then at a speed that is two steps faster for 30 seconds. Performs rocking motion.

Then, after a predetermined time (swing time), for example, 1 to 15 minutes elapses from the detection by the cry sensor 16, the swing stop operation of a predetermined pattern is started. This swing time can be arbitrarily set.
The swing speed can be set, for example, in 9 steps. The motor is controlled at the rotational speed (rpm), but converted into a cycle, for example, 3.53 seconds, 2.86 seconds, 2.40 seconds, 2.07 seconds, 1.82 seconds, 1.62 There are nine stages: seconds, 1.46 seconds, 1.33 seconds, and 1.22 seconds. When entering a rocking stop operation of a predetermined pattern from the state of rocking at such a rocking speed, first, the one-step speed is decelerated. For example, after 20 seconds have elapsed, the speed is further reduced by one step. Further, for example, after 20 seconds have elapsed, the speed is reduced by one step, and further, for example, after 10 seconds has elapsed, the speed is reduced by one step.
Here, the period of each stage is not a constant value but a variable value that varies depending on an arbitrarily set rocking speed.

  When a cry is detected during deceleration according to such a rocking stop pattern, the preset rocking time (for example, 15 minutes) is reset and timed from the beginning, that is, the remaining rocking time is preliminarily determined. After returning to the set time (for example, 15 minutes), the predetermined time (for example, 30 seconds) from the detection is also reset and timed from the beginning. Swing is performed at a speed two steps faster than the set speed.

  The cry sensor can be disabled / enabled, and a case where the cry sensor is disabled will be described. Pressing the “RUN” button on the controller causes the crib floor to swing at a preset swing speed. During swinging, the time and speed can be arbitrarily changed by the controller. Further, when the “strong shaking” button is pressed during the swinging, the swinging is performed in a state where the speed is two steps faster than a preset swinging speed for 30 seconds, for example, and after 30 seconds, the original speed is restored. Then, after the preset swing time has elapsed (the remaining swing time is 0), the bed floor stops shaking according to a predetermined swing stop pattern.

  Here, a cry sensor has been described as an example of a sensor that detects human body information and starts swinging by the swinging means. However, any sensor that detects human body information and starts swinging by the swinging means may be used. For example, the sensor may not necessarily be a cry sensor, for example, a temperature sensor that detects the baby's body temperature and starts swinging by the swinging means, or an operation sensor that detects the baby's movement and starts swinging by the swinging means. May be used.

FIG. 3 is a schematic diagram illustrating a state in which the upper member of the crib to which the present invention is applied is moved. FIG. 3 (a) shows a state in which the upper member is slid and the upper member is positioned on the front side where the height of the enclosure member is low. Even if the child stands up, the baby bed 1 can be prevented from falling.
FIG. 3B shows a state in which the upper member is slid and the upper member is positioned on the rear side where the height of the surrounding member is higher than the front side. By positioning, the infant can be easily put on and taken down from the front side without sliding the front enclosure member 6 that can slide substantially vertically downward substantially vertically downward.

  FIG. 4 is a schematic view for explaining a state in which the front enclosing member of the crib to which the present invention is applied is slid substantially vertically downward. Since the upper edge of the front enclosure member 6 slid substantially vertically downward is located at substantially the same height as the mattress 8 placed on the floor board, the infant can be easily put on and taken down from the front side.

  FIG. 5 is a schematic view showing an example of a use state of a baby bed to which the present invention is applied. The height from the indoor floor to the mattress 8 laid on the floor board of the crib 1 is about 30 cm. As shown in FIG. 5, the parent 17 slides the front enclosure member 6 substantially vertically downward, While sitting on the floor of the room, the baby laid on the mattress 8 of the crib 1 can be relieved.

  As described above, in the crib of the present invention, the swinging means such as a motor stops the swinging of the floor board after controlling to a predetermined pattern. Sudden stoppage of swinging feeling can be prevented, so that it is difficult for infants to feel uncomfortable. As a result, the number of times an infant cries can be reduced, and the parenting burden on the parent can be reduced.

  In addition, since the baby bed of the present invention has a plurality of stages in which the predetermined pattern has the swing speed decreasing with time, it is possible to make it difficult for the baby to feel the swing change, and the baby feels a comfortable swing. You can fall asleep.

  In the crib of the present invention, the cry sensor detects the cry and starts swinging by the swinging means. The swinging period of the swinging means until the predetermined time elapses from the detection by the sensor is the predetermined time. Since it is shorter than the rocking cycle of the rocking means after the lapse, by detecting the crying at night and immediately increasing the rocking speed, it stops the crying, and by slowing the rocking speed, it makes a comfortable rocking state. , You can put it to sleep as it is.

In addition, the baby bed of the present invention is attached to the opening formed in the enclosure member and covers the opening, and the flexible member that can be seen through the inside is soft even if the baby collides, so there is a low possibility of injury. Because the inside can be seen through, the mother can feel at ease with the baby's appearance from the outside.
Moreover, since the height of the front enclosure member is lower than the height of other enclosure members, the baby bed of this invention can carry an infant on a bed easily from a front enclosure member side, or can take down from a bed.
Further, since the front enclosure member can slide in a substantially vertical direction, the infant can be placed on the bed more easily or can be lowered from the bed by sliding the front enclosure member substantially vertically downward.
In addition, the upper member can be slid toward the front enclosure member, so that the baby can be prevented from falling from the baby bed even if the baby stands up.
