FIGS. 1-4 show a base seat I for providing rocking and swing motion in various directions for a bed (not shown) or a chair (not shown) fixedly positioned thereon. Thebase seat 1 comprises afixation base 10, arocking mount 20, adrive device 30, aswivel mount 40, and anactuator 50. - The
fixation base 10 includes abottom portion 11 and a plurality ofrollers 14. Thebottom portion 11 is formed by a rectangular frame for being placed on a ground. Four supportingarms 12 extend upwardly from thebottom portion 11 and are arranged pair by pair. Therollers 14 are rotatably disposed above thebottom portion 11 and arranged in two parallel rows each including twolower rollers 15 and oneupper roller 16. Eachupper roller 16 is rotatably disposed between paired two supportingarms 12 in a way that theupper roller 16 is located higher than thelower rollers 15 and theupper roller 16 is located between the twolower rollers 15 in a same row. In another embodiment, the shape of thebottom portion 11 and the number, arrangement and installation of therollers 14 may be modified. - The
rocking mount 20 is disposed above thefixation base 10 and reciprocatingly and inclinedly moveable relative to thefixation base 10. Therocking mount 20 includes abearing portion 22, apivot portion 23 and twoarc rails 24. Thebearing portion 22 is formed by a square frame, thepivot portion 23 is disposed at about a center of thebearing portion 22, and thearc rails 24 are disposed under two lateral sides of thebearing portion 22 and in contact with therollers 14. Thearc rail 24 has a shape of a sector of a circle and protrudes downwardly. Thearc rail 24 is formed by a round tube such that the transverse cross-section of thearc rail 24 shows a circular profile and thearc rail 24 is linearly in contact with therollers 14. Eacharc rail 24 extends through a space between one pared supportingarms 12, such that therocking mount 20 can be stably installed with thefixation base 10 without escaping from thefixation base 10. With aforesaid design, therocking mount 20 is reciprocatingly and inclinedly moveable relative to thefixation base 10, as shown inFIGS. 6 and7 , i.e. swingable back and forth relative to thefixation base 10 like a pendulum having a pivot point suspended above therocking mount 20 that serves as a bob and a rod connected between the pivot point and therocking mount 20, thereby having stable structure and being operated with low noise. Further, four slidingcontact members 26 are mounted on thebearing portion 22 of therocking mount 20 for contacting theswivel mount 40. In this embodiment, the slidingcontact member 26 is realized as a universal ball member. In another embodiment, the structure of therocking mount 20 may be modified as long as therocking mount 20 is capable of reciprocatingly and inclinedly moving relative to thefixation base 10. - The
drive device 30 is disposed between thefixation base 10 and therocking mount 20 and capable of driving therocking mount 20 to reciprocatingly and inclinedly move relative to thefixation base 10. For thedrive device 30, various designs may be used. In this embodiment, thedrive device 30 comprises apower source 32, acrank 36 and alink 38. Thepower source 32 is disposed on thefixation base 10 and provided with apower output shaft 33. Specifically, thepower source 32 is composed of amotor 34 and areduction gearbox 35. Thecrank 36 has an end connected with thepower output shaft 33. Two ends of thelink 38 are pivotally connected with thecrank 36 and therocking mount 20. As such, when themotor 34 is operated to drive theoutput shaft 33 to rotate, therocking mount 20 is driven by thelink 38 through thecrank 36 to reciprocatingly and inclinedly move relative to thefixation base 10, as shown inFIGS. 5-7 . Thedrive device 30 provided in this embodiment is structurally reliable and can be operated with low noise. - The
swivel mount 40 is rotatably disposed above therocking mount 20. In this embodiment, theswivel mount 40 is formed by a square frame and provided at a center thereof with acoupling portion 42 coupled with thepivot portion 23 of the rockingmount 20 in a way that theswivel mount 40 is rotatable about thecoupling portion 42, which serves as a pivotal axis of theswivel mount 40, relative to the rockingmount 20. Anextension portion 43 extends laterally from thecoupling portion 42 and has a distal end pivotally connected with an end of theactuator 50. Theactuator 50 has the other end pivotally connected with the bearingportion 22 of the rockingmount 20. In this embodiment, theactuator 50 is an electric actuator cylinder having acylinder body 52 and aslidable rod 54 capable of extending out of and retracting into thecylinder body 52, such that the total length of theactuator 50 is changeable dynamically and adjustably. Thecylinder body 52 is pivotally connected with the bearingportion 22 of the rockingmount 20, and theslidable rod 54 is pivotally connected with theextension portion 43. By means of continual retracting and extending motion of theslidable rod 54 relative to thecylinder body 52, the total length of theactuator 50 is continuously changed. Further, theswivel mount 40 is provided with a circular ring-shapedabutment portion 44 in contact with the slidingcontact members 26, such that theswivel mount 40 can be smoothly rotated relative to the rockingmount 20. In this way, when theactuator 50 extends its length, theswivel mount 40 can be driven to rotate relative to the rockingmount 20 at an angle of 90 degrees, as shown inFIGS. 8 and9 . In another embodiment, the coupling structures of theswivel mount 40 and the rockingmount 20 may be modified as long as theswivel mount 40 can be rotated relive to the rockingmount 20. Furthermore, theswivel mount 40 may be configured by a circular disc, such that the bottom surface of the circular disc can serve as theabutment portion 44 directly. Moreover, it is only required that the two ends of theactuator 50 are pivotally connected with the rockingmount 20 and theswivel mount 40, respectively. In other words, the pivotally connecting locations between the actuator 50 and the rockingmount 20 and between the actuator 50 and theswivel mount 40 are not limited to the locations disclosed in this embodiment. - With the above-mentioned structural design, when a bed or a chair is installed on the base seat I of the present invention, and more specifically when the bed or the chair is fixedly mounted on the
swivel mount 40, thedrive device 30 can drive the bed or the chair to perform a swing motion in a given direction, such as a back-and-forth direction or a left-and-right direction. Such wing motion is like a hammock or pendulum motion, which is an ergonomic, relaxing and comfortable motion. Besides, because there are only relative rotational or rolling movements among the elements of thebase seat 1 without the relative displacements thereamong, the base seat I can be operated in a very lower noise. Further, by means of rotating theswivel mount 40 relative to the rockingmount 20 through the operation of theactuator 50, the swinging direction of the bed or the chair can be adjusted from an existing direction to another desired direction, i.e. from a left-and-right direction to a back-and-forth direction or any arbitrary direction for example. With this direction adjustable function, the mental fatigue or physical fatigue of a user caused by the swing motion in a single, monotone direction can be avoided, and the user can adjust the swing mode according to personal preference. That is, the base seat I of the present invention can provide more diverse and flexible user experience, having great market potential. - Based on the technical features of the present invention, various modifications to the structure of the base seat lof the present invention may be made. For example, the installation locations of the sliding
contact members 26 and theabutment portion 44 can be exchanged, i.e. the slidingcontact members 26 are provided at the bottom of the swivel mount and the abutment portion is provided at the top of the rocking mount. Further, the slidingcontact member 26 can be realized by a bearing, such as a ring bearing, and one or more sliding contact members can be used in thebase seat 1, i.e. at least one sliding contact member is sufficient. The number of the arc rails 24 of the rockingmount 20 is also not limited to the number of the previous embodiment. That is, the rockingmount 20 may be equipped with one or more arc rails 24. For example,FIG. 10 shows a base seat 1a according to a second embodiment of the present invention, which has a structure basically same as thebase seat 1 of the first embodiment, except that the rockingmount 20a has only onearc rail 24a, and a single row ofrollers 14a is provided above the bottom portion 11a of thefixation base 10a in a way that therollers 14a are in contact with thearc rail 24a. In this embodiment, therollers 14a in a single row include twolower rollers 15a and oneupper roller 16a, and thearc rail 24a is formed by a rectangular tube having a rectangular transverse cross-section, such that thearc rail 24a is in contact with therollers 14a in a linear contact manner. In this way, the rockingmount 20a can also be stably and firmly installed with thefixation base 10a. - In another aspect, various modifications to the structures of the fixation base and the rocking mount may be made.
FIG. 11 shows abase seat 1b according to a third embodiment of the present invention, which has a structure basically same as thebase seat 1 of the first embodiment, except that there is no roller disposed to thefixation base 10b and two arc rails 60 is disposed above thebottom portion 11b, and there is no arc rail disposed to the rockingmount 20b and two rows ofrollers 62 are disposed under the bearingportion 22b and in contact with the two arc rails 60. Therollers 62 arranged on each row include twoupper rollers 64 located above onearc rail 60, and alower roller 66 located under thearc rail 60 and between the twoupper rollers 64. As such, thedrive device 30b can drive the rockingmount 20b to reciprocatingly and inclinedly move relative to thefixation base 10b, as show inFIG. 12 . - In another embodiment, the
actuator 50 may be omitted. In this case, user may manually adjust the rotational angle of theswivel mount 40 relative to the rockingmount 20. In still another embodiment, for simplifying the structure of the base seat of the present invention, the swivel mount may be even omitted. In this situation, when installing the bed or chair to the rockingmount 20, the user may set them at a specific installation angle according to the user's preference angle of swing. - To sum up, the base seat of the present invention, which is adapted for supporting a bed or a chair thereon, provides swing motion in various directions and in fulfillment with ergonomics so as to avoid user's metal or physical fatigue and to provide diverse and flexible user experience, making the user feel more relaxing and comfortable.
