Abstract

PURPOSE:To obtain a rocking chair and a rocking bed for a baby with least noise and impact by making use of repulsive force generated between identical magnetic poles faced with each other, thereby letting the front section or the rear section of a rocking link be moved up and down, which comes in contact with the floor. CONSTITUTION:A rocking chair is composed of a pair of links 7 and 7', and of a solenoid section S formed by a pair of upper and lower solenoids 11 and 12, the former is provided vertically for chair frames 1 and 1' and underneath the chair frames in the direction of arm rest 2 and 2' symmetrically and in parallel, and the later is provided vertically for the center section of a connecting plate 9 linked between both of the links. When a switch 17 is turned on with a timer 15 set for a time required, magnetism of each solenoid 11 and 12 becomes repulsive so as to push the forward section of the rooking chair down at the fulcrum of a shock absorbing rubber 13 coming in contact with the floor for starting rocking. And when inertia motion is over, rocking motion in fore and aft starts repeating, which returns to a suspension position. A bed can be constituted in the similar manner. Thus, the arrangement being such that magnetic repu lsion is utilized by the solenoid S, there is neither noise nor vibration.

Description

DETAILED DESCRIPTION OF THE INVENTION A [Object of the Invention] (Field of Industrial Application) The present invention relates to a rocking chair and a rocking bed for infants, which are equipped with an automatic rocking device of the same mechanism.

(Prior Art) Conventionally used rocking chairs and beds for infants have generally not been proposed to be equipped with a rocking device that operates automatically.

For example, Utility Model Application No. 58-123739, Utility Model Application No. 59-10
No. 1755, Utility Model No. 59-143462, Utility Model Application No. 1987
The vertical rocking chairs disclosed in publications such as No. 11648 and Japanese Utility Model Application No. 62-87556, etc., all have ingenuity added to the shape and structure of the swinging part itself. 6
The chairs disclosed in Japanese Utility Model Publication No. 0-109451 and Japanese Utility Model Application Publication No. 62-48255 are designed so that the former can simply be turned over horizontally, while the latter can simply be swung both vertically and horizontally.

Other rocking chairs and rocking beds for infants offered on the market today, including the above-mentioned proposals, are those that are rocked by the user's own motion or by another person, and are equipped with an automatic rocking device. has not been proposed yet.

(Problem to be Solved by the Invention) The purpose of a rocking chair is to indulge in meditation, comfort, and induce sleep while rocking, and therefore it is desirable to induce sleep without any effort on the part of the user. A device equipped with a rocking device is desired.

In addition, since the mother has to constantly rock the rocking bed for infants in order to put the child to sleep, she is unable to take her hands off the bed until the child falls asleep, causing her to neglect housework.

In order to solve these issues, it is necessary to automate the rocking operation,
Moreover, by providing the notch mechanism, the purpose can be fully achieved.

Therefore, it is conceivable to use a motor as a power source as an automated device, but in this case, the rotating noise of the motor is annoying and a speed reduction device must be added, making the device complicated.

That is, it is necessary to provide a hydraulic or pneumatic pump, a compressor, an electromagnetic valve, an actuator, etc., but these are inappropriate because they cause noise and oscillation, causing discomfort to the user, and rather diminishing the oscillation effect.

l [Structure of the Invention] (Means for Solving the Problems) A rocking chair and a rocking bed for infants equipped with an automatic rocking device of the present invention have a mechanism that causes extremely little contact between the devices, and the drive The source utilizes the repulsive force caused by opposing magnetic poles of the same polarity and moves the front or rear part of the swinging link in contact with the floor up and down, providing an extremely effective means with virtually no noise or impact. be.

It is desirable to use non-magnetic materials such as aluminum laminate, stainless steel, synthetic resin, etc. for all the materials constituting the solenoid parts, except for the solenoid.

Next, the connecting plate (9) is connected to both swing links (7) as described above.
(7') between the screws (10) (10') (10") (1
0'''), and a limit switch (19) is attached to an appropriate position on the connecting plate, and wired as shown in FIG.

In addition, on the lower surfaces of both swing links (7) (7'), as shown in Fig. 2, elastic bells (8) (8') are provided with protrusions on the surface.
) For example, by adhering a rubber belt, it is possible to provide a cushioning effect to prevent the rocking chair of the present invention from slipping and to allow it to swing silently and stably.

Note that the swing link may be made of an appropriate material such as wood, metal, or synthetic resin.

Next, the stop position of the rocking chair is set approximately equal to the center of gravity, and a limit switch (19) is installed on the connecting plate (9) with the circuit closed.

As mentioned above, the solenoids (11) and (12) are installed perpendicularly to the floor surface, and the cushioning rubber (3) is in contact with the floor surface, and the opposing solenoids (11 and 12) are installed to the extent that they do not touch each other. Since there is a gap, no impact sound is emitted. The installation position of the solenoid section (S) is preferably about 25 mm away from the center of gravity toward the tip of the foot, and the swing starting torque at this point is about 4 kg.

Furthermore, the swing links (7) (7') are preferably substantially straight in a direction forward from the center of gravity to prevent the body from leaning forward too much.

In addition, depending on the swinging operation, the contact point of the swing links (7) (7') with the floor moves rearward via the elastic belts (8) (8'), but the center of gravity remains constant. , when the swing inertia ends, it returns to the stop position.

Figure 7 shows the solenoid part (S) with the swing link (7) (7).
') is shown below.

In this case, it is designed to keep the sitting position tilted backwards, so the chair frame (1) and the swing link (

Starting from the cushioning rubber (13) that emits and touches the floor,
Push up the front of the rocking chair to start rocking, and once the inertia is over, it will return to the rest position.

By repeating the limit switch input, the swinging motion is constantly repeated in the back and forth direction.

The swinging speed is at intervals of 2 to 3 seconds, assuming that the front and back length of the swing link is approximately 1 meter.

Maximum torque is required to start rocking, but since the rocking chair operates slowly, the magnetic repulsion force is maintained at maximum until it starts, and once rocking begins, it gradually repulses within the magnetic field. The force becomes weaker, and it exhibits an effect for original motion that is ideal for rocking motion.

(Second Embodiment) FIG. 6 shows an embodiment of a rocking bed for infants equipped with an automatic rocking device according to claim 2 of the present invention.

That is, the infant bed of the present invention has a bed body (20

Hereinafter, with a structure similar to that shown in FIGS. 3 and 5, an infant bed similar to that shown in the first embodiment, which can be automatically rocked by magnetic repulsion, can be obtained.

・1 [Effects of the Invention] As mentioned above, the present invention is applied to a rocking chair and a rocking bed for infants equipped with an automatic rocking device, but the present invention is not limited to the conventional rocking chair and rocking bed for infants.
The person must either move his or her upper body back and forth to shift the center of gravity and cause the object to swing, or kick the object with his or her toes to cause the object to swing.

Infant beds also have to be moved manually.

Therefore, if it stops working, it is just a chair or a bed,
There's no benefit.

Due to the action of the automatic rocking device, the original purpose of rocking is to change your mood, provide a sense of comfort, and give you a sense of mental satisfaction.
It is relaxing and helps recover from fatigue, allowing infants to sleep peacefully.

There are many reasons why infants and young children have difficulty, but it is especially difficult to understand the cause in infants.

If illness is excluded, they can be broadly classified into (A) hunger, (B)
(C) If the diaper is dirty, (C) If you want to be held, etc.

(A) and (B) are the most important and require the mother's help, but (C) means spoiling, which increases the number of times the child is picked up, and the child develops the habit of being spoiled.
As a result, I was forced to constantly carry my baby on my back.

By providing an automatic rocking bed for infants, the rocking motion helps to stabilize the infant's mental state, discipline brings good results, and also leads to a reduction in the mother's labor.

In conventional rocking chairs and beds for infants, the rocking links that come into contact with the floor during rocking slide and move to one side each time the chairs and infant beds are rocked, so they must be returned to their original positions each time.

A swing link (7) equipped with an automatic swing device provided by the present invention
) (7') uses magnetic repulsion from a solenoid instead of a motor as its power source, so there is no noise or vibration, and there is no slippage between the swing link and the floor. (8) (8") prevents the chair and bed from moving during rocking, and by setting a timer, stable and quiet rocking can be continued during that time.

In addition, it has great effects, such as being able to provide power at a much lower cost than a motor.
