EXERCISING DEVICE Filed D60. 1l, 1941 l NVENTO R ATTO R N EYS Patented Nov. "7, 1944 "UNITED STATE s PATENT 1 Claim.

This invention relates to an exercising devicev and has for an object to provide a device of this character including a frame, a seat, and a front cross bar underneath which the user may hook his feet while seated upon the seat to permit of the body being bent backwardly and forwardly at the hips to simulate rowing a boat to the end that the muscles will be strengthened, as well as improved digestion and circulation greatly promoted.

A further object is to provide a device of this character having a seat adjustable longitudinally of the frame and accommodating the device to persons having long or short legs.

A further object is to provide a device of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and'which will not easily get out of order.

With the above and other objects in view, the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim Without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a perspective view of an exerciser constructed in accordance with the invention and showing the same in use.

Figure 2 is a perspective view of the exerciser.

Figure 8 is a fragmentary bottom planA view showing the adjustable seat.

Figure 4 is a detail cross sectional view taken on the line 4-4 of Figure 3.

Referring now to the drawing in which like characters of reference designate similar parts in the various Views, the exercising device comprises a frame I0 having side members each .formed of a horizontal bottom bar Il, an upwardly and rearwardly inclined top bar I2, a `U-shaped bar I3 connecting the front -ends of the top and bottom bars, and a vertical bar III connecting the top and bottom bars near the rear ends. The rear ends of the bottom bars project beyond the rear ends of the top bars to prevent the device from pivoting upward on the rear end when in use.

An X-shaped brace member I5 connects together `the rear ends of the side members. A iront cross bar I6 connects together the front ends of the top bars I2. The frame constructed as above described may be formed of tubing, rods or similar material, and preferably all Vjoints are Welded to provide a frame in a single integral piece throughout.

A seat I1, formed of plywood or othermaterial, is provided on the bottom face with spaced longitudinal guide ribs I8 adapted to extend along the inner sides of the top bars I2 and form guides for holding the seat against lateral movement but permitting of the seat being slid longitudinally on the top bars of the frame to various adjusted positions. A pair of bolts I9 are engaged through the rear end of the seat and through the ribs I8 near the rear ends of Vthe latter. A pair of longer bolts 20 are engaged "through the seat and through the ribs near the bolts 20. The clamp bar 22 projects beyond the ribs I8 and when the wing nuts 2l are tightened, the clamp bar clamps the seat I'l rmly in adjusted position on the top bars I2 of the frame.

In use, the operator hooks his toes underneath the front cross bar4 I6, which consequently forms a foot rest orfgrip, and sits himself upon the seat, preferably with his arms folded so that his entire weight is supported without the use of the arms. Tlien the operator sways forwardly and backwardly, as shown by full lines and by dotted lines respectively, in Figure i, to exercise the muscles oi the legs, stomach and back, as in rowing a boat.

The seat Il is adjusted longitudinally of the frame I0 by loosening the wing nuts 2l and moving the seat to the selected adjusted position, then tightening the wing nuts in order that operators of various heights, and consequently having long or short legs, may conveniently exercise With the device.

From the above description it is thought that the construction and operation of the invention will be fully understood Vwithout further eX- planation.

What is claimed is:

An exercising device comprising a pair of transversely spaced approximately U-sha-ped side sections, each of said sections including a 1ongitudinal bottom bar having its front end curved arcuately upward and joining a top longitudinal bar, said top bar being disposed to assume an upwardly diverging relationl from the front-to the rear of the bottom bar and terminating short of the latter, a vertical bar secured to and ex- With and in close proximity to the top bars to prevent transverse displacement of the seat, a clamp bar extended transversely of the underside of the seat and top bars, a pair of bolts depending from said ribs and extending through open-r ings in the clamp bar, and a wing nut tted on the outer end of each of said bolts for releasably forcing the clamp bar into gripping engagement with the top bars.
