Detailed Description of the Embodiments

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0015] Fig. 1 shows a schematic diagram of a relaxation apparatus in accordance with an embodiment of the present invention. As depicted in Fig. 1, the relaxation apparatus 10 includes a base 11 having a bottom portion 11a placed on the floor (not shown), a rocking machinism 12 as a rocking unit provided to the base 11 and a body-supporting member 13 as a body-supporting unit and a rocking member driven by the rocking mechanism 12.

[0016] The rocking mechanism 12 has a motor 20, a reduction gear 21, a crank mechanism 22 and link members 23. The motor 20 is provided on the bottom portion 11a of the base 11 and the operation thereof is controlled by a controller 24 provided on the bottom portion 11a. The reduction gear 21 is also provided on the bottom portion 11a of the base 11. The reduction gear 21 is operationally coupled with the motor 20 and serves to reduce the power of the motor 20. Further, the motor 20 has a position sensor (not shown) such as an encoder that detects the number of revolutions and revolutionary position.

[0017] The crank mechanism 22 has two connecting rods 22a and 22b, and converts the rotating motion of the reduction gear 21 into a large circular motion. The base end of the connecting rod 22a is connected to and rotates with the axis of the reduction gear 21, while its leading end is rotatably connected to the base end of the other connecting rod 22b. The leading end of the connecting rod 22b is connected to the lower portion of a rectangular frame 25 to which the body-supporting member 13 is fixed.

[0018] The aforementioned base 11 also has a support frame 11b protruded upward from the bottom part 11a. The base ends of the linkages 23 are rotatably connected to the upper portion of the support frame 11b at an interval, while their leading ends 22b are rotatably connected to the lower portion of the rectangular frame 25. The two linkages 23 rotate around their base ends and, therefore, the body-supporting member 13, fixed to the base part 25, can be rocked back and forth by the power delivered from the crank mechanism 22, like a rocking chair.

[0019] The body-supporting member 13 of a chair shape includes a seat portion 30 which is fixed to an upper portion of the rectangular frame 25 so that they can move together, a back portion 31 attached to the rear side of the seat portion 30, and an ottoman 32 fixed at the front side of the seat portion 30, which are integrally formed. As viewed from above, the back portion 31 has a width gradually increased from a head support portion 31a on the rear side thereof, which supports the head of the user M, to a waist support portion 31b that supports the waist portion including the arms of the user M, so that the width Y at the waist support 31b is larger than the width X at the head support 31a. On the other hand, the width of the body-supporting member 13 is gradually decreased from the front side of the waist support portion 31b, i.e., the rear side of the seat portion 30 to the front edge of the ottoman 32, forming a curved shape as a whole.

[0020] As shown in Figs. 1 and 2, a manipulator 41 is installed on the side of the body-supporting member 13 (the back portion 31), which can be attached and detached by a manipulator holder 40 and a main power switch 42 is installed on the side surface 30a of the seat portion 30, which can turn on and off the power supply.

[0021] As shown in Fig. 3, the manipulator 41 includes various switches 43 to 49, such as course selection switches 43, a swing regulator switch 44, a reclining-angle regulator switch 45, a volume regulator switch 46, a vibration regulator switch 47, an air-bag regulator switch 48 and a start-up switch 49, each of which having an electrostatic sensor 50 (see Fig. 4); and indicators 51 that can respectively show on and off positions of the various switches 43 to 49.

[0022] The course selection switches 43 include multiple switches 43a, 43b, 43c and 43d to select multiple courses (four courses A to D in the present embodiment) and, as shown in Fig. 4, according to the selections of the respective switches 43a to 43d, corresponding control signals are output to the controller 24 from the control selector 41a where multiple rocking patterns are set up.

[0023] The swing regulator switch 44 is electrically connected to a speed regulator 41b and an amplitude regulator 41c for regulating respectively the speed and amplitude of a rocking motion, as shown in Fig. 4. By the user operating the swing regulator switch 44, the speed and amplitude of the rocking motion of the body-supporting member 13 can be changed in three steps.

[0024] By the user operating the reclining-angle regulator switch 45, a reclining control signal is outputted to the controller 24 through the reclining regulator 41d, as shown in Fig. 4, and the controller 24 that receives the signal controls the reclining driver 13a properly to regulate the reclining angle of the body-supporting member 13.

[0025] The volume regulator switch 46 is to regulate the volume of a speaker (not shown) and in the present embodiment the volume can be regulated in five levels. The vibration regulator switch 47 is to regulate the degree of vibration of vibrating parts (not shown) and in the present embodiment the vibration can be regulated in five levels. The air-bag regulator switch 48 is to change the amount of expansion of air bags (not shown) and in the present embodiment the expansion can be regulated in five levels. The start-up switch 49 is to turn the relaxation apparatus 10 on and off and the controller 24 can control the respective parts by operating the start-up switch 49 to turn it on.

[0026] The indicators 51 include light-emitting diodes within a transparent cell of a casing of the manipulator 41 and are installed in the interior of the respective switches 43 to 49, and level displays 44a, 46a, 47a and 48a provided to show the current status of the motion by the respective switches 44, 46, 47 and 48.

[0027] In the relaxation apparatus 10 configured as described above, the controller 24 controls the motor 20 to rock the body-supporting member 13 back and forth in a relaxation motion that provides a user with an effective relaxation effect.

[0028] During a relaxation rocking, the indicators 51 for the respective switches 43 to 49 are turned off so that they are restrained from being recognized by the user. During the relaxation rocking, the sensors 50 output signals to the controller 24 if the respective switches 43 to 49 are operated by the user. The controller 24 that receives signals from the sensors 50 controls the corresponding indicators 51 to be turned on. At the same time, that is, if the respective switches 43 to 49 including the sensors 50 are operated by the user, the controller 24 controls the rocking mechanism 12 to reduce the speed of the rocking motion of the body-supporting member 13 to a predetermined level α as shown in Fig. 5.

[0029] If a user operates the minute switches 43 to 49 of the manipulator 41 while gazing at them during the rocking motion, he/she could have felt nausea. In the present embodiment of the relaxation apparatus 10, however, the speed of the rocking motion of the body-supporting member 13 gets reduced to the predetermined value α so that unpleasant stimulations to the semicircular canal of the user may be restrained and, therefore, it becomes possible to restrain him/her from feeling nausea.

[0030] Next, the characteristic effects of the present embodiments will be described.

(1) The relaxation apparatus 10 includes the manipulator 41 that gives instructions to a controller 24 based on an operation performed by a user. In addition, when it is determined that the user operates the manipulator 41 during a rocking motion, the controller 24 controls the rocking mechanism 12 to reduce the speed of the rocking motion of the body-supporting member 13. That is, when the manipulator 41 is operated during a rocking motion, because the speed of the rocking motion of the body-supporting member 13 gets reduced, unpleasant stimulations to the semicircular canal of the user may be restrained and, therefore, it becomes possible to restrain him/her from feeling nausea.

(2) The manipulator 41 includes the indicators 51 that can indicate operation states of respective switches 43 to 49. In addition, if it is determined that the manipulator 41 is not operated during a rocking motion, the indicators are turned off. In other words, by turning off the indicators 51 while the user does not operate the manipulator 41, it is possible to make the user hard to perceive the indicators 51 even though he/she recognizes the presence of the manipulator. Hence, the user being restrained from gazing at the indicators, unpleasant stimulations to the semicircular canal of the user may be restrained and, therefore, it becomes possible to restrain him/her from feeling nausea.

(3) The manipulator 41 includes the indicators 51 with the light-emitting diodes and the operation switches 43 to 49 which give instructions to the controller 24. Hence, even though the user recognizes the manipulator 41 during a rocking motion, because the manipulator 41 has a plain and simple configuration, the user can be restrained from gazing at the indicators, and, therefore, it becomes possible to restrain him/her from feeling nausea.

(4) Because the manipulator 41 is installed on the side of the body-supporting member 13, the manipulator 41 moves together with the body-supporting member 13 during a rocking motion. Accordingly, the relative position of the head of a user with the manipulator can be kept unchanged during the rocking motion. As a result, even though the user recognized the manipulator 41, unpleasant stimulations to the semicircular canal of the user may be restrained and, therefore, it becomes possible to restrain him/her from feeling nausea.

[0031] The embodiments of the present invention may be modified as described below.

[0032] Although, in the embodiment described above, the switches having an electrostatic sensor are employed to determine whether a user would operate the manipulator 41 or not, other types of switches such as tactile switches, rubber switches or membrane switches may be employed instead. In addition, whether a user would operate the manipulator 41 or not may be determined by installing a switch mechanism on a manipulator holder 40 and using it to detect the attachment or detachment of the manipulator 41. Besides, whether a user would operate the manipulator 41 or not may be determined by, e.g., a proximity sensor detecting the user's body (e.g., a hand) at a distance from the manipulator 41 when the user's hand approaches the manipulator 41.

[0033] Although, in the embodiment described above, the speed of a rocking motion is set to be the predetermined value α while the user operates manipulator 41 (see Fig. 5), it may be reduced at a constant rate in proportion to the initial speed before the operation.

[0034] Although, in the embodiment described above, the indicators 51 are turned off when the manipulator 41 is not in operation during a relaxation rocking, they may be turned on at all times.

[0035] Although, in the embodiment described above, the manipulator 41 includes the indicators 51 with the light-emitting diodes and the various switches 43 to 49, the present invention is not limited thereto. For example, the manipulator may include a liquid crystal display.

[0036] Although, in the embodiment described above, the indicators 51 have the light-emitting diodes, other lighting parts may be employed.

[0037] Although, in the embodiment described above, the body-supporting member 13 is rocked back and forth, the present invention is not limited thereto and, for example, it may be rocked from side to side.

[0038] Even though it is not mentioned explicitly in the embodiment described above, air bags may be installed on the various parts of the body-supporting member 13 in order to provide with a relaxation effect such as massaging by carrying out suitable expansion and contraction thereof.

[0039] Even though it is not mentioned explicitly in the embodiment described above, the controller 24 may control the motor 20 to carry out a refresh rocking that awakes a user in a relaxation (sleeping) state, for example, by having the amplitude or frequency of a rocking motion higher after the relaxation motion than during the relaxation motion.

[0040] Even though it is not mentioned explicitly in the embodiment described above, there may be provided a mechanism for generating music or vibration corresponding to the relaxation rocking or refresh rocking.

[0041] While the invention has been shown and described with respect to the embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
