Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a rowing exerciser, and more particularly to an angle-adjustable rowing exerciser, which can be conveniently adjusted to the desired angle of inclination.

A variety of exercising apparatus have been disclosed for different exercising purposes, and have appeared on the market. Regular multipurpose exercising apparatus are commonly heavy and expensive, and not suitable for home use. Regular simple climbers, rowers, stationary bicycles are less expensive, and suitable for home use. However, these exercising apparatus are designed for one particular exercising purpose only.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide an angle-adjustable rowing exerciser, which is practical for exercising different parts of the body. It is another object of the present invention to provide an angle-adjustable rowing exerciser, which is inexpensive to manufacture, and suitable for home use. It is still another object of the present invention to provide an angle-adjustable rowing exercising, which can be conveniently adjusted to fit different exercising requirements. According to one aspect of the present invention, the angle-adjustable rowing exerciser comprises a wheeled base frame, a fixed mattress and a pivoted mattress supported on the base frame, a transverse frame bar pivotally mounted on the base frame at the bottom, two handlebars respectively connected to the ends of the transverse frame bar for turning by hand to rotate the transverse frame bar, and two actuating bars perpendicularly and fixedly connected to the transverse frame bar and forced to tilt the base frame or the movable mattress up and down upon turning of the handlebars. According to another aspect of the present invention, the transverse frame bar comprises two adjustable ratchet connectors at its two distal ends respectively connected to the handlebars, enabling the handlebars to be adjusted to one of a series of angular positions relative to the transverse frame bar.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Referring to FIGS. from 1 through 4 , an angle-adjustable rowing machine is sown comprised of an elongated base frame 1 , a first mattress 2 , a pair of handlebars 3 , a transverse frame bar 4 , a second mattress 5 , and a pair of actuating bars 6 .

The base frame 1 is equipped with rollers 10 for easy moving on the floor. The first mattress 2 is fixedly mounted on the base frame 1 at one end. The second mattress 5 has one end pivoted to a middle part of the base frame 1 by a pivot 11 . When lied down, the second mattress 5 is supported on the base frame 1 and aligned with the first mattress 2 in a line. The transverse frame bar 4 is pivotally mounted on the base frame 1 below the second mattress 5 , having two ratchet connectors 40 at two distal ends thereof. The handlebars 3 are respectively connected to the ratchet connectors 40 , and adjusted to the desired angle relative to the transverse frame bar 4 . The actuating bars 6 are perpendicularly and fixedly connected to the transverse frame bar 4 , each having a distal end mounted with a roller 60 . The base frame 1 may set holes 12 at the side of the second mattress 5 (see FIGS. 11 and 12 ). The holes 12 can insert a bar to confine the inclined angle of the actuating bars 6 .

Referring to FIGS. from 5 through 10 and FIG. 4 again, the angle-adjustable rowing exerciser can be operated in any of a variety of operation modes. For example, the user can lie on the mattresses 2 and 5 , sit, kneel or stand on the first mattress 2 , or sit on the heels above the first mattress 2 , and turn the handlebars 3 back and forth when keeping the rollers 60 of the actuating bars 6 stopped at the floor (see FIGS. 4 , 7 , 8 and 10 ) or the bottom of the second mattress 5 (see FIGS. 5 , 6 and 9 ). When turning the handlebars 3 back and forth, the second mattress 5 or the base frame 1 is tilted up and down. By means of adjusting the angular position of the handlebars 3 relative to the transverse frame bar 4 , the exercising amount is relatively adjusted. Referring to FIGS. 11 and 12 , when insert a bar into the holes 12 . Because the actuating bars 6 is confined by the bar. So the second mattress 5 only can incline an angle.

It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed.
