Description

  The present invention relates to a swinging device that swingably supports a holding device such as a chair, a bed, or a toy.

As a conventional swinging device, an arc-shaped plate-like leg member is arranged on the lower surface of the holding device, and the holding device can be swung in one direction by rolling and rolling the leg member and the floor. In addition, a bowl-shaped (substantially spherical) leg member is arranged on the lower surface of the holding device, and the holding device can be swung in multiple directions by rolling and rolling the leg member and the floor. And a holding device that is swingably supported by a fulcrum, and a cushion spring is disposed at the swinging end of the holding member.
Some game machines are provided with a complicated drive mechanism so that an operator seated on a seat can swing in the front-rear and left-right directions.

  In the case where the arc-shaped leg member is provided, the swinging direction is limited to one direction, and for example, the relaxation effect due to the swinging cannot be exhibited sufficiently. In the case where the bowl-shaped leg member is provided, the rocking in multiple directions is possible, but the bowl-like leg member is not stable because it is bowl-shaped. Since these leg plates have a structure in which the leg members are brought into contact with the floor or the like with the arc plate or the bowl-like leg members, there is a risk of injury by pinching a finger or the like in the gap between the leg members and the floor when making contact. In addition, there was also a risk of damaging the floor to which it was transferred. In the case where a cushion spring is provided at the swing end, the swing operation may not be performed smoothly, for example, when the swing end swings in a certain direction, the return operation is performed with a time lag. In addition, in a game machine having a complicated drive mechanism, the equipment configuration becomes complicated, and an increase in the manufacturing cost of the apparatus cannot be avoided.

  The present invention has been made in view of the above circumstances, and can swing stably and smoothly in any direction (at least in the front-rear direction and the left-right direction), and can be injured even if a finger or the like is sandwiched between the floor surface. Another object of the present invention is to provide a rocking device that is less likely to damage the floor surface and that is simple in structure and can be manufactured at a relatively low cost.

The swing device according to claim 1 of the present invention includes a bag body in which a gas such as air is sealed, and a holding device that is placed on the bag body and receives and holds a human body, and at least the bag body. A bag body height changing mechanism that changes the height of the peripheral edge portion of the bag body at the peripheral edge portion and changes the center of gravity balance of the entire apparatus to generate a swinging force in the human body received by the holding device on the bag body. The bag body height changing mechanism is provided with a pair of sandwiching plates that sandwich at least the peripheral edge of the bag body from above and below, and a drive unit that directly and intentionally changes the interval between the sandwiching plates, The drive means is actuated to directly and intentionally narrow the gap between the clamping plates to directly and intentionally change the height of the peripheral edge of the bag body, thereby changing the balance of the center of gravity of the entire apparatus. And
Thus, the driving means constituting the bag body height changing mechanism is operated to directly and intentionally narrow the gap between the sandwiching plates so that at least the peripheral portion of the bag body is sandwiched from the vertical direction by the sandwiching plates, By changing the height of the front and back directly and intentionally, the center of gravity balance of the entire device is changed, so that the holding device tilts in the direction in which the height is reduced, and the human body held by the holding device swings Be made.
A game machine machine according to a second aspect of the present invention includes the swing device according to the first aspect, and a person sits on a seat as the holding device and operates an operation means such as a handle or an operating rod. In the game machine, the driving means of the bag body height changing mechanism is actuated in response to the operation of the operation means to directly and intentionally reduce the interval between the sandwiching plates to reduce the height of the peripheral edge of the bag body. The structure is characterized in that a desired swinging force can be applied to a person sitting on the seat by changing the balance of the center of gravity of the entire apparatus directly and intentionally.
As a result, when the operator operates the operating means such as the handle or the operating rod while sitting on the seat, the driving means of the bag body height changing mechanism is operated according to the operation of the operating means to directly and intentionally hold the gap between the holding plates. Thus, the height of the peripheral portion of the bag body is directly and intentionally changed to change the balance of the center of gravity of the entire apparatus, and a desired swinging force is applied to the person sitting on the seat.
In the swing device of the present invention, the holding device may be a chair. In this case, for example, the swing device can be used as a swing mechanism such as a rocking chair.
In the swing device of the present invention, the holding device may be a bed. In this case, for example, the swing device can be used for sleep or nap, can also be used for a baby's or infant's cradle, etc. Further, if a drive mechanism is used, a swing suitable for sleep is automatically set. Can also be given to humans.
In the swing device of the present invention, the holding device may be a toy. In this case, the toy can be swung by exercising on the toy on which the person rides, and if the drive mechanism is used, a swing set according to the preset or the scene is given to the person on the toy. You can also.

As described above, according to the rocking device of the present invention, the following effects can be obtained.
(1) Since it has a relatively simple structure in which the interval between the sandwiching plates is made variable so that the swing is generated, it can be manufactured at low cost.
(2) The driving means constituting the bag body height changing mechanism is actuated to narrow the gap between the clamping plates directly and intentionally so that at least the peripheral edge of the bag body is sandwiched from the vertical direction by the clamping plates, By changing the height of the front and back directly and intentionally, the center of gravity balance of the entire device is changed, so that the holding device tilts in the direction in which the height is reduced, and the human body held by the holding device swings Be made.
(3) When sitting on the seat and operating the operating means such as the handle or the operating rod, the driving means constituting the bag body height changing mechanism is operated in accordance with the operation of the operating means to directly set the interval between the holding plates. In addition, it is possible to intentionally reduce the height of the vicinity of the peripheral edge of the bag body directly and intentionally, thereby changing the balance of the center of gravity of the entire apparatus, and thereby imparting a desired swinging force to a person sitting on the seat. .

  A swing device according to an embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a rocking device 1 according to an embodiment of the present invention. In this device, a seat chair (which constitutes a part of the holding device of the present invention) 3 for holding a human body is placed and supported on a bag body 2 in which a gas such as air is enclosed. As the bag body 2, a sheet made of a flexible material such as rubber and bonded at four peripheral edges and formed into a bag shape is used. As the bag body 2, a cushion-like shape having a planar shape corresponding to the seat surface portion of the seat chair 3 and a thickness of about 10 cm can be adopted. The bag body 2 is preferably provided with an air intake / exhaust valve so that a gas such as air can be enclosed or exhausted from the intake / exhaust valve. Thus, by adjusting the pressure inside the bag body 2 and the height of the bag body 2, it is possible to provide appropriate elasticity (oscillation) according to the weight of the seated person and the like.

  Note that the bag body 2 may have only one air chamber as described above, or may be partitioned into a plurality of chambers. The plurality of chambers are preferably formed along the peripheral edge of the bag. What is called a donut shape without an air chamber in the center may be used. Further, the bag body may be constituted by a plurality of bag bodies separated from each other, and each bag body may be arranged at at least four corners of a pedestal 4 to be described later. Appropriate shapes such as an outer spherical shape and a dice shape can be adopted as the shapes of the bags separated from each other. When arrange | positioning along with the peripheral part of the base 4, you may arrange | position mutually spaced apart so that adjacent bag bodies may not contact, and may arrange | position in contact with each other. In addition, it is possible to adjust the pressure in each air chamber or the plurality of bags by providing an intake / exhaust valve in each or a part of each of the plurality of air chambers or the plurality of bags. It is suitable for making it correspond.

  On the upper surface of the bag body 2, a substantially rectangular base 4 substantially corresponding to the outer dimensions is fixed to the bag body by means such as adhesion. Guide portions 5 having a substantially U-shaped cross section are formed integrally with the pedestal 4 on both sides of the front portion of the pedestal 4. The pedestal 4 constitutes a part of the holding device.

  The seat chair 3 is attached to the seat surface portion 6 so that the back portion 7 can be reclined by the support shaft 8, and the front end portion of the guide portion 5 is slidably fitted on the side surface of the seat surface portion 6 in the depth direction of the seat surface. An extending concave groove 6a is formed. A screw hole into which the thumbscrew 11 is screwed is formed in the side edge portion of the back portion 7, a connecting portion 9 is formed in the rear end portion of the base 4, and a connecting lever 12 is provided between the screw hole and the connecting portion 9. Are pivotably mounted around a wing screw 11 screwed into the screw hole and a pin 10 inserted into the connecting portion 9. When the thumbscrew 11 is tightened, the swing is fixed, and when the thumbscrew 11 is loosened, the swing is possible. Here, the connection lever 12, the connection part 9, and the screw hole constitute the interlocking mechanism of the present invention.

  A piston rod of an air cylinder 14 is connected to the support shaft 8, and an operating arm 15 is connected to an operating lever attached to the air cylinder 14. When the operating arm 15 is rotated, the operating lever is released, and the restraint by the air cylinder 14 that restrains the reclining operation of the back portion 7 until then is released, so that the reclining operation of the back portion 7 can be performed.

  When the thumbscrew 11 is loosened, the operating arm 15 is rotated to release the operating lever, and the back portion 7 is reclined, the seat surface portion 6 is moved back and forth in conjunction with the reclining operation of the back portion 7. That is, when the back portion 7 is tilted in the direction approaching the horizontal, the connecting lever 12 swings around the pin 10 of the connecting portion 9 and the seat surface portion 6 is moved forward. At this time, the concave groove 6a formed on the side surface of the seat surface portion 6 is guided by the guide portion 5 formed on the pedestal 4 and smoothly moved forward without detachment. This interlocking operation corrects the center of gravity of the weight, including the weight of a person sitting on the seat 3, so that it does not deviate significantly from the center of the bag body 2 even when the reclining operation is performed in a normal sitting posture. The

  According to the present swinging device 1, the seated person sitting on the seat chair 3 is swung back and forth and right and left by elastically deforming the bag body 2 back and forth and right and left. Such swinging has a function of relaxing the mind and body and also has an exercise effect on the body. In addition, since it can swing not only in the front-rear direction but also in any direction such as the left-right direction or the oblique direction, the relaxation effect and the physical exercise effect can be further enhanced. Further, in the seat chair 3 on the bag body 2, the back portion 7 can be reclined at an arbitrary angle with respect to the seat surface portion 6 by an air cylinder 14 or the like, according to the preference of the seated person from the sitting position to the sleeping position. The posture can be taken, the swinging can be caused in the desired posture, and the above effects can be optimally exhibited.

  In addition, the seat 3 can be removed from the guide part 5 of the base 4, and it can isolate | separate from the bag body 2, and the seat 3 can be used alone. Thus, when it is desired not to cause oscillation, it can be used alone, which is preferable. There is an advantage in that it is not necessary to prepare both a seat chair that causes swing and a seat chair that does not swing. In addition, when sitting or standing on the pedestal 3 with the seat 3 removed, the bag 2 under the pedestal 3 tilts back and forth and left and right due to a slight change in balance. By doing so, it can also be used as a so-called equilibrium maintenance game.

  2 to 6 show a rocking device 21 according to another embodiment of the present invention. 2 is a side view, FIG. 3 is a front view, FIG. 4 is a rear view, FIG. 5 is a plan view, and FIG. 6 is a side view showing a reclining state. Like the swinging device 1, the swinging device 21 has a seat chair (which constitutes a part of the holding device of the present invention) 23 for holding a human body on a bag 2 in which a gas such as air is enclosed. It was placed on and supported by. Constituent elements similar to those of the oscillating device 1 are denoted by the same reference numerals and description thereof is omitted.

  A spherical ball (returning urging mechanism) 24 made of an elastic material such as rubber or synthetic resin is disposed in a corner portion of the bag body 2 that is rectangular in plan view. The spherical ball 24 is disposed so as to be located in an inner region of the base 4, and is disposed such that a gap is formed between the lowermost portion of the spherical ball 24 and the bottom portion of the bag body 2.

  When the bag body 2 bends back and forth or tilts left and right, the spherical ball 24 on the side whose height has been reduced comes into contact with the bottom of the bag body 2 and the weight of a person sitting on the seat chair 3 is also reduced. The included weight is applied to the spherical ball 24 and the spherical ball 24 is elastically deformed. This elastic repulsive force acts on the seat 3 via the pedestal 4 and a load acts in a direction to return the seat 3 to its original state. In addition, when using on a pedestal from which the seat is removed as described above and using it as a balance sense maintenance and breeding game machine, the return function of the spherical ball 24 is effective and preferable.

  As shown in FIGS. 2 and 4, a connecting portion 25 is provided on the back surface of the back portion 7 so as to protrude side by side. The connecting portion 25 is formed with a screw hole into which the thumbscrew 11 is screwed. Since the connecting portion 25 is provided on the back surface of the back portion 7, the connecting lever 12 is positioned on the back surface side of the back portion 7, and does not interfere with the operation when performing an operation such as reclining.

  As shown in FIG. 2 and the like, a link bar 26 to which an armrest 27 is attached is connected to the seat surface portion 6 and the back portion 7. Even when the back portion 7 is reclined by these link bars 26, the armrest 27 moves while maintaining a substantially horizontal state.

  FIG. 7 shows an oscillating device 31 according to still another embodiment of the present invention. This is provided with a restraining mechanism 30 for restraining the seat chair so as not to be affected by the elastic deformation of the bag body 2 when sitting on the seat chair 3 or the like.

  The restraining mechanism 30 has connecting portions 35 and 36 projecting from a pedestal 34 fixed on the bag body 32 toward the bag body side, and leg members 37 serving as holding legs are connected to the connecting portions 35 and 36. Yes. The leg member 37 includes a flat belt-shaped landing member 38 extending in the front-rear direction of the bag body 32, a connecting portion 38a provided on the landing member 38, and connecting members 39, 40 attached to the connecting portion 38a in a swingable manner. The upper end of the connecting member 39 is swingably connected to the connecting portions 35 and 36. An operation lever 43 for operating the restraining mechanism 30 is provided so as to protrude outward, and this operation lever 43 is integrally fixed to the connecting member 40. A cross beam 44 is integrally fixed between connecting members 40 provided in the left-right direction of the bag body 32. A projecting member 45 is fixed to the intermediate portion of the cross beam 44 in a position substantially parallel to the connecting member 40, and the leading end of the projecting member 45 is connected to a connecting portion 47 formed to project from the back surface of the base 34. 48 are connected.

  The operation state of the restraining mechanism 30 will be described. Normally, the state is as shown in FIG. Here, as shown in FIG. 7A, when the operating lever 43 is raised, the connecting member 40 is rotated by the shaft support portion, and the horizontal beam 44 is also rotated integrally. The protruding member 45 protruding from the horizontal beam 44 also rotates integrally and comes into contact with the bottom surface of the bag body 32. At the same time, since the connecting member 40 is swingably connected to the landing member 38 via the connecting portion 38 a, the landing member 38 is supported by the connecting portions 35 and 36 and swings to contact the bottom surface of the bag body 32. In this state, the load applied to the pedestal 34 is supported by the connecting members 38, 40, the landing member 38, and the protruding member 45, and does not act on the bag body 32. Even if a load is applied to the chair, the bag 32 is in a stable state without being bent. Therefore, the sitting operation is not hindered by the elastic deformation of the bag body 32.

  When the sitting on the seating chair is finished and the seating posture is stabilized, the operation lever 43 is returned to the state shown in FIG. 7B, so that the connecting member 40 and the landing member 38 are retracted upward as in the original state. As a result, the elastic deformation of the bag body 32 is not prevented, and the bag body 32 inherently elastically deforms according to changes in the load applied to the seat chair or the pedestal 34 or the position of the center of gravity, thereby exerting the swing function. be able to.

  FIG. 8 shows a rocking device 51 according to still another embodiment of the present invention. Like the swinging device 1, the swinging device 51 has a seat chair (which constitutes a part of the holding device of the present invention) 3 for holding a human body on a bag 2 in which a gas such as air is enclosed. It was placed on and supported by. Constituent elements similar to those of the oscillating device 1 are denoted by the same reference numerals and description thereof is omitted.

  A coil spring (returning urging mechanism) 54 made of an elastic material such as metal is disposed in the bag body 2 in the vicinity of the corner portion of the rectangular shape in plan view. The coil spring 54 is disposed so as to be located in a region inside the base 4. It may be provided inside or outside the bag body 2. Further, not only those having a single spring constant but also those in which the spring constant changes stepwise or gradually in accordance with the amount of deformation of the spring.

  FIG. 9 shows a rocking device 61 according to still another embodiment of the present invention. This device is provided with a drive mechanism for swinging the holding device in a pedestal 60, and this drive mechanism is composed of a center-of-gravity moving mechanism 62 for moving the center of gravity of the entire device in a substantially horizontal plane. The center-of-gravity moving mechanism 62 includes a left-right direction center-of-gravity moving mechanism 63 that moves the center of gravity in the left-right direction of the seat surface portion and a front-rear direction center-of-gravity moving mechanism 73 that moves the center of gravity in the front-back direction of the seat surface portion.

  The left-right direction center-of-gravity moving mechanism 63 is provided with a weight 65 movably along a guide rail 66 provided along the left-right direction of the seat surface, and a screw rod 68 coupled to the drive shaft of the drive motor 67 is attached to the weight 65. It is screwed into a threaded hole formed through. The front-rear direction center-of-gravity moving mechanism 73 is provided with a weight 75 movably along a guide rail 76 provided along the front-rear direction of the seat surface, and a screw rod 78 connected to the drive shaft of the drive motor 77 on the weight 65. It is screwed into a threaded hole formed through. According to the left-right direction center-of-gravity moving mechanism 63 and the front-rear direction center-of-gravity moving mechanism 73, the weights 65, 75 can be moved by a desired amount by rotationally driving the drive motors 67, 77. The position can be changed almost in the horizontal plane. A person sitting on a holding device such as a seat chair placed on the pedestal 60 is subjected to a swinging action in accordance with the movement of the center of gravity by the center of gravity moving mechanism.

  FIG. 10 shows a rocking device 81 according to still another embodiment of the present invention. This is a game machine in which a swing device 81 having a drive mechanism similar to that shown in the swing device 61 is applied to a car drive device which is a kind of game machine, that is, a swing provided with the pedestal 60 and the like. The apparatus is provided with a handle 82, an accelerator pedal 83, a brake pedal 84, and the like.

  When the handle 82, the accelerator pedal 83, and the brake pedal 84 are operated according to the screen displayed in front of the swinging device 81, the drive motors 67 and 77 are driven according to the operation, and the weights 65 and 75 are moved back and forth and left and right. As a result, the swing acceleration of the front, rear, left and right acts on the player who is seated on the chair. A realistic game operation can be performed by the swing acceleration that is experienced. In this way, the weights 65 and 75 are relatively simple to move, the manufacturing cost is low, and they are suitable for applications such as installation at home and playing games.

  The action of the swing device 81 will be specifically described. For example, when the handle 82 is turned to the right, the weight 65 is moved to the left side. As a result, a swinging action of tilting to the left works for the player sitting on the seat. This means that the player feels as if centrifugal force was working on the side opposite to the direction in which the handle was cut, and that the game operation with a sense of reality is performed by changing the position and struggling to counter this swing Can do. Further, when the accelerator pedal 83 is depressed, the weight 75 is moved rearward. As a result, a swinging action of tilting backward works on the player sitting on the seat. The player feels as if the acceleration is working backwards. When the brake pedal 84 is depressed, the weight 75 is moved to the front side. As a result, a swinging action that tilts forward acts on the player sitting on the seat. The player feels as if the acceleration worked positively. A game operation with a sense of realism can be performed in the same manner by changing the posture or struggling so as to resist the swinging in the front-rear direction.

  In order to maximize the sense of realism, it is preferable to optimally control the movement of the weights 65 and 75 by detecting various factors such as the rotational angular speed of the handle 82, the depression speed and the loosening speed of the brake pedal 84 and the accelerator pedal 83. . This control is suitable to be performed by a computer.

  The driving mechanism is not limited to one that changes the position of the center of gravity by the movement of the weight as described above, and various modes can be adopted. For example, a plurality of pairs of sandwiching plates that sandwich a part of the bag body from the vertical direction are provided on the front, rear, left, and right sides of the bag body, the spacing between the pair of sandwiching plates is narrowed, and the bag body is sandwiched, so that at least the peripheral portion of the bag body You may comprise from the bag body height change mechanism which changes height. In this case, for example, when the handle 82 is turned to the right, the gap between the holding plates provided on the left side is narrowed to cause the left side to swing, and when the accelerator pedal 83 is depressed, the holding pin provided on the rear side is provided. When the brake pedal 84 is depressed, the distance between the holding plates provided on the front side is reduced to cause the front side to swing. It is possible to perform a game operation with a sense of presence similar to that of the swing device according to the embodiment.

  Here, in the case of generating a swinging action by narrowing the interval between the sandwiching plates, the rotation of the handle 82 is mechanically transmitted to the sandwiching plates arranged on the left and right to narrow the interval between the sandwiching plates, and similarly the accelerator. The amount of depression of the pedal 83 or the brake pedal 84 may be transmitted to a sandwiching plate that is mechanically arranged at the front and back to narrow or widen the spacing between the sandwiching plates. If such a mechanism is used, the function as the drive mechanism can be exhibited by a simpler mechanism than when the drive motors 67 and 77 and the screw rods 68 and 78 are used.

  FIG. 11 shows a rocking device 91 according to still another embodiment of the present invention. In this device, a swing device similar to that shown in FIG. 10 is applied to an air flight device which is a kind of game machine. A control stick 92 is provided in place of the handle 82, and when the control stick is operated to turn left and right, and to move up and down, the player can similarly swing the seat chair back and forth and right and left to feel the acceleration. To give to.

  In the above example, the drive mechanism is actively driven in accordance with the intention or operation of the game player or the like sitting on the seat chair, so that the seated person swings. Regardless of this, a predetermined or prescribed swing may be generated to passively cause the seated person to swing.

  For example, a holding device such as a cradle that accommodates an infant or an infant may be adopted, and a swinging motion that the infant or infant is likely to fall asleep by programming may be generated by a drive mechanism. In addition, adopting a toy such as a wooden horse or an automobile or a motorcycle on which an infant rides as a holding device, a swinging movement in which the infant is interested (for example, experiencing when running on a running horse, car or motorcycle) It may be one that is programmed and generated by a drive mechanism.

  In the swing device according to each of the above embodiments, a seat mounted on a pedestal so that it can be slid in the front-rear direction is shown. It is also possible to form a rectangular recess or projection of the size, and attach the seat to the pedestal by fitting into a projection or recess formed on the pedestal corresponding to the recess or projection. . It is particularly suitable for those that are not reclined.

  In the swing device according to the above embodiment, the restraining mechanism 30 including the leg member 37 is provided, but the restraining mechanism is not limited thereto. For example, an extension leg that can be driven back and forth in the vertical direction by an electric motor or the like is provided at the bottom of the pedestal, and the pedestal is supported by the extension leg so that the load does not reach the bag body when the extension leg protrudes. In the state where the extended leg is retracted, the bag may be loaded as usual.

  In the oscillating device according to each of the embodiments described above, the seat surface portion automatically slides back and forth in conjunction with the reclining of the back portion, but is not limited thereto. For example, a concavo-convex portion formed by repeating a plurality of convex portions and concave portions along the front-rear direction is formed on the pedestal, and the concave and convex portions provided with concave portions and convex portions that are fitted into the respective convex portions and concave portions. It may be formed along the front-rear direction on the back surface of the seat surface portion, and the fitting position between the uneven portion of the base and the uneven portion of the back surface of the seat surface portion may be adjusted back and forth. This has the advantage that a complicated interlocking mechanism is unnecessary, and the position of the chair can be finely adjusted in accordance with the movement of the center of gravity according to the reclining operation.

  In the swaying device according to each of the above embodiments, the case where a chair is mainly used as the holding device has been described as an example. However, as the holding device, for example, a wooden horse, a car, a motorcycle, etc. Such a toy may be used. In the case of a bedding, even if the bedding is fixedly formed on the pedestal, a bedding attachment frame may be formed on the pedestal, and the bedding may be detachably attached to the bedding attachment frame. The removable one can also be used as one that does not rock the bed. In the case of the toy described above, it is preferable to attach a toy mounting part to the pedestal and fit the mounting part formed on the toy side corresponding to the mounting part so as to be slidable, swingable or pivotable. . For example, a mounting member on the pedestal side is a cylindrical member that protrudes from substantially the center of the pedestal, and the mounting component of the toy can be a cylindrical member or a cylindrical member that fits into the cylindrical member. In addition, you may comprise only a pedestal as a holding | maintenance apparatus, and it can utilize as an above-mentioned balance feeling maintenance breeding game machine.
