bottom seat 30 and theswingable frame 31, further includes a second swing arm unit 43 (two second swing arms) mounted pivotally on thebottom seat 30 via apivot shaft 431 in such a manner that the secondswing arm unit 43 is connected pivotally to one end of the firstswing arm unit 42 and theswingable frame 31 so that the first and secondswing arm units pivot shaft 431, thereby reciprocally moving theswingable frame 31 relative to thebottom seat 30 in forward and rearward directions. In this embodiment, the end of the firstswing arm unit 42 is provided with amovable rod 421 for pivotally connected with the secondswing arm unit 43 such that thefirst swing arm 42 is movably simultaneously and reciprocally with the secondswing arm unit 43. In addition, the secondswing arm unit 43 has an upper end provided with apivot shaft 433. Theswingable frame 31 further includes aconnection element 311 which is connected pivotally to thepivot shaft 433 such that the secondswing arm unit 43 can reciprocally move theswing frame 31 in forward and rearward directions. - The swing adjustment mechanism includes a
displacement member 50 mounted on the secondswing arm unit 43 in such a manner to simultaneously cause movement of themovable rod 431 of the firstswing arm unit 42 along a longitudinal length of the secondswing arm unit 43, thereby altering a distance between themovable rod 421 of the firstswing arm unit 42 and thepivot shaft 431 of the secondswing arm unit 43. In other word, the firstswing arm unit 42 and the secondswing arm unit 43 are movable simultaneously and reciprocally in different swinging angles, and hence driving theswingable frame 31 in different swinging angles relative to thebottom seat 30. In this embodiment, a guidingslot 432 is formed through the secondswing arm unit 43 such that themovable rod 421 of the firstswing arm unit 42 extends through the guidingslot 432. Thedisplacement member 50 further includes adisplacement element 53 disposed adjacent to the secondswing arm unit 43 and has a pivot end connected pivotally to themovable rod 421 such that sliding action of themovable rod 421 within the guidingslot 432 simultaneously results in movement of thedisplacement element 53 along the longitudinal length of the secondswing arm unit 43. The swing adjustment mechanism further includes a second driving source having asecond motor 51, ascrew shaft 52 driven by thesecond motor 51. Thedisplacement element 53 has ascrew coupler 531 sleeved rotatably around thescrew shaft 52 such that activation of thesecond motor 51 results in rotation of thescrew shaft 52, thereby driving thedisplacement element 53 and moving themovable rod 421 within the guidingslot 432 in the secondswing arm unit 43. In other words, the distance between themovable rod 421 of the firstswing arm unit 42 and thepivot shaft 431 of the secondswing arm unit 43 is adjusted so is the swinging angle (in wavy manner) of theswingable frame 31 relative to thebottom seat 30. - In one embodiment of the present invention, a
carrier plate 60 is disposed above theswingable frame 31 so as to permit sleeping of person thereon such that due to regular swinging movement of thecarrier plate 60 together with the swingable frame 31 (in adjusted swinging angle) relative to thebottom seat 30, the sleeping quality and effects to a sleeper is enhanced. - Referring to
FIG. 6 , when the reciprocally movable carrier of the present invention in application, activation of thecrankshaft 41 by thefirst motor 401 of thefirst driving source 40 causes theeccentric portion 411 to move the firstswing arm unit 42 reciprocally in forward and rearward directions relative to thebottom seat 30, wherein, themovable rod 421 and the secondswing arm unit 43 simultaneously and reciprocally rotate about thepivot shaft 431. At this time, theeccentric portion 411 of thecrankshaft 41 causes the greatest movement “L” of thefirst swing arm 42 while a distance “R1” is defined between themovable rod 421 of thefirst swing arm 42 and thepivot shaft 431 of thesecond swing arm 43 such that the first and secondswing arm unit pivot shaft 431 within “θ1” so that thecarrier plate 60 together with the swingable frame 31 (in adjusted swinging angle) move in regular swinging angle relative to thebottom seat 30, the sleeping quality and effects to a sleeper is enhanced. -
FIG. 7 shows a state after the swinging angle of theswingable frame 31 relative to thebottom seat 30 is adjusted according to an individual requirement. When adjusting, thesecond motor 51 is activated to drive thescrew shaft 52 so as to move thedisplacement element 53 in a downward direction of the secondswing arm unit 43, which action causes rotation of theeccentric portion 411 of thecrankshaft 41 and moving themovable rod 421 downward along the guidingslot 432 in the secondswing arm unit 43, thereby narrowing the distance between themovable rod 421 of the firstswing arm unit 42 and thepivot shaft 431 of the secondswing arm unit 43 to “R2”. - As illustrated in
FIG. 8 , when thefirst motor 401 of thefirst driving source 40 is activated, thecrankshaft 41 is driven such that theeccentric portion 411 drives the firstswing arm unit 42 reciprocally in forward and rearward directions relative to thebottom seat 30, which action causes rotation of the secondswing arm unit 43 about thepivot shaft 431 due to downward movement of themovable rod 421 in the guidingslot 432. At this time, theeccentric portion 411 of thecrankshaft 41 causes the greatest movement “L” of thefirst swing arm 42 while the smallest distance “R2” is defined between themovable rod 421 of thefirst swing arm 42 and thepivot shaft 431 of thesecond swing arm 43 such that the first and secondswing arm unit pivot shaft 431 within “θ2” so that thecarrier plate 60 together with theswingable frame 31 move in regular swinging angle (greater than that ofFIG. 6 ) relative to thebottom seat 30, the sleeping quality and effects to a sleeper is enhanced. - Referring to
FIG. 9 , in case the user of the reciprocal movable carrier of the present invention wishes to narrow the swinging angle of theswingable frame 31, he can activate thesecond motor 51 so as to drive thescrew shaft 52, thereby causing upward movement of thedisplacement element 53 relative to the secondswing arm unit 43, which action causes rotation of theeccentric portion 411 of thecrankshaft 41, where themovable rod 421 moves upward along the guidingslot 432 in the secondswing arm unit 43 so that a distance of “R3” is defined between themovable rod 421 of thefirst swing arm 42 and thepivot shaft 431 of thesecond swing arm 43. - As best shown in
FIG. 10 , when thefirst motor 401 of thefirst driving source 40 is activated, thecrankshaft 41 is driven such that theeccentric portion 411 drives the firstswing arm unit 42 reciprocally in forward and rearward directions relative to thebottom seat 30, which action causes rotation of the secondswing arm unit 43 about thepivot shaft 431 due to upward movement of themovable rod 421 in the guidingslot 432. At this time, theeccentric portion 411 of thecrankshaft 41 causes the greatest movement “L” of thefirst swing arm 42 while the greatest distance “R3” is defined between themovable rod 421 of thefirst swing arm 42 and thepivot shaft 431 of thesecond swing arm 43 such that the first and secondswing arm unit pivot shaft 431 within a small swinging angle “θ3” where thecarrier plate 60 together with theswingable frame 31 move in the small swinging angle relative to thebottom seat 30, thereby meeting the desired angle of an individual requirement using the reciprocal movable carrier of the present invention and hence the sleeping quality and effects to a sleeper is enhanced. -
FIG. 11 is a lateral view of the reciprocally movable carrier according to the present invention, illustrating theframe rods 32 connected pivotally theswingable frame 31 and thebottom seat 31 to form a non-parallel rectangular connection rod structure in order to move the swingable frame in a wavy manner. In this embodiment, the non-parallel rectangular connection rod structure has an upper part and a lower part having a width smaller than the upper part. -
FIG. 12 is a lateral view of the reciprocally movable carrier according to the present invention, illustrating theframe rods 32 connected pivotally theswingable frame 31 and thebottom seat 31 to form a non-parallel rectangular connection rod structure different from that shown inFIG. 11 . In this embodiment, the non-parallel rectangular connection rod structure has an upper part and a lower part having a width greater than the upper part. - Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
