Description:

FIELD OF THE INVENTION

The present invention relates to an exerciser and more particularly, to an exerciser which swings in multiple directions.

BACKGROUND OF THE INVENTION

A conventional swinging exerciser such as the surfing simulation exerciser generally includes a base with a wheel to which an eccentric shaft is connected. A link has one end connected with the shaft and the other end of the link is connected with a frame which is connected with a board on which the user stands and tries to keep balance to simulate the surfing poses. Two arms are connected to the frame and when the wheel rotates, the link is activated and the frame is restricted by the arms so that the board moves up and down. The wheel can be driven by a servo motor. However, the conventional swinging exerciser cannot provide sufficient exercising functions to the users who feel boring after using the swinging exerciser for a period of time.

The present invention intends to provide an exerciser which swings in multiple directions so that the users feel interesting and exercise during keeping balance when using the exerciser of the present invention.

SUMMARY OF THE INVENTION

The present invention relates to an exerciser and comprises a main frame with a swinging unit and a transmission unit connected to two ends thereof respectively. The transmission unit has an eccentric member connected thereto so as to be connected with two cranks and a connection unit. The connection unit has an upper portion so as to be connected with a seat unit. A base portion is connected to an underside of the connection unit and has one end pivotably connected with the swinging unit and the other end of the base portion is pivotably connected with the eccentric member. The transmission unit drives the eccentric member, the connection unit and the swinging unit to move the seat unit in multiple directions.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 5, the exerciser of the present invention comprises a main frame 10 having two support legs on two ends thereof so as to be put on the floor. A swinging unit 20 and a transmission unit 30 are respectively connected to the two ends of the main frame 10. Two pivots 11 extend from two sides of the main frame 10 and swinging unit 20 has two passages 21 on one end thereof and a transverse bar 22 on the other end of the swinging unit 20. The two pivots 11 are engaged with the two passages 21.

The transmission unit 30 includes a belt wheel 33 which has an axle 32, two cranks 31 are connected to the axle 32. A belt wheel 33 and an eccentric member 40 are mounted to the axle 32 respectively. An elongate board which has one end connected tot eh axle 32 and the other end of the elongate board is connected with an initial wheel 34. A central shaft 341 extends from a side of the initial wheel 34 and a belt 35 is connected between the central shaft 341 and the belt wheel 33. A tension wheel 36 is connected to the main frame 10 so as to adjust the tension of the belt 35.

The eccentric member 40 includes two plates 41 with a link 42 connected therebetween. Two ends of the link 42 are connected between two respective opposite ends of the two plates 41, and the other two respective opposite ends of the two plates 41 are respectively connected to the axle 32 and one of the two cranks 31.

A connection unit 50 has an upper portion 51 extending from a top thereof and a seat unit 60 is connected to the upper portion 51. A base portion 52 is connected to an underside of the connection unit 50 and has one end pivotably connected with the swinging unit 20, the other end of the base portion 52 is pivotably connected with the eccentric member 40. The base portion 52 of the connection unit 50 includes two separated rods and two pivot holes 521 are defined through the two separated rods respectively. The transverse bar 22 of the swinging unit 20 is pivotably engaged with the two pivot holes 521. One of the two separated rods of the connection unit 50 has an extension link 53 connected thereto which has a connection hole 531 through which the link 42 of the eccentric member 40 extends.

The seat unit 60 includes a seat post 61 which is inserted into the upper portion 51 which is a connection tube of the connection unit 50. A pin 511 extends through a wall of the upper portion 51 and is inserted into one of positioning holes 62 defined in the seat post 61 so as to adjust the height of the seat 60 of the seat unit 60. The seat unit 60 further includes two handles 64 and a control panel 65 is connected between the two handles 64. The control panel 65 is electrically connected to the tension wheel 36 so as to control the tension of the belt 35.

When the user sits in the seat 63 and treads the pedals on the two cranks 31, the transmission unit 30 is activated so as to drive the eccentric member 40, the connection unit 50 and the swinging unit 20 to move the seat unit 60 in multiple directions. The travel path of the seat unit 60 is decided by the swinging unit 20 and the length of the extension link 53.

FIGS. 6 to 8 show another embodiment of the exerciser of the present invention, wherein a main frame 10 has a swinging unit 20 connected to an end thereof and two inclined and parallel rods 38 are connected on a top of the main frame 10. A transmission unit 30 is connected to the other end of the main frame 10 and an eccentric member 40 is connected to the transmission unit 30.

A connection unit 50 has an upper portion 51 which includes two parallel links 512 so as to be connected with a seat unit 60. A base portion 52 connected to an underside of the connection unit 50 and has one end pivotably connected with the swinging unit 20, the other end of the base portion 52 is pivotably connected with the eccentric member 40. The seat unit 60 has a seat post 66 and a roller unit 67 is located on two ends of the seat post 66 so as to be engaged with the two parallel links 512. A roller 661 is connected to an underside of the seat post 66 and engaged between the two inclined and parallel rods 38. The roller unit 67 includes two upper rollers 671 and two lower rollers 672, the two upper rollers 671 and the two lower rollers 672 roll on the two parallel links 512 of the connection unit 50.

The eccentric member 40 includes a board 43 and a hole 431 is defined through an end of the board 43. The transmission unit 30 has an output shaft 37 which is engaged with the hole 431 in the board 43. A pivot tube 432 extends from the other end of the board 43 and is pivotably connected to the base portion 52 of the connection unit 50.

When the transmission unit 30 is activated, the seat unit 60 moves in the same way as the first embodiment, by the guide of the inclined and parallel rods 38 and the roller 661, the seat unit 60 further moves inclinedly back and forth.

FIG. 9 shows yet another embodiment of the exerciser in FIG. 6 of the present invention, wherein the transmission unit 30 includes a gear set which includes a plurality of gears.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
