ROWING -TYPE EXERC I S ING EQUIPMENT Original Filed July 31, 1964 I nvenlors PETkOS E4 M1 A410 5444 A tlorneys United States Patent 3,380,737 ROWING-TYPE EXERCISING EQUIPMENT Petros Elia and Kiki Elia, both of 7 Lowther Hill, London, SE. 23, England Original application July 31, 1964, Ser. No. 386,706, now Patent No. 3,261,606, dated July 19, 1966. Divided and this application Mar. 2, 1966, Ser. No. 531,222 Claims priority, application Great Britain, Aug. 14, 1963, 32,169/ 63 6 Claims. (Cl. 272-72) This invention relates to equipment for physical training, and aims at the provision of simple and effective means for rowing exercises.

The invention consists in physical training equipment comprising a base member, supporting means upstanding from said base member, a beam pivoted to said supporting means at a point intermediate of its ends, a seat on said beam on one side of said beam pivot, and means for connecting a flexible line to a point of the beam on the side of said beam pivot opposite to said seat, a lever also pivoted to said supporting means at a point intermediate of its ends, a handle adjacent to one end of said lever, means for connecting a flexible line to a point of said lever on the side of the lever pivot opposite to said handle, pulley means on said base member, and a flexible line running in said pulleys connected at its ends respectively to the said means on said beam and said lever for connection of a flexible line thereto.

The lever is manually operable and connected to the beam by a cable. When the manually operable lever handle is pulled, it tends to rock the beam or the like supporting the seat and thus to lift the seat with the operator sitting therein.

The invention will be clearly understood from the following description of forms (given, however, merely by way of example) which it may assume, and this descrip tion will be more readily followed by reference to the accompanying drawings wherein FIGURES 1 and 2 represent, respectively in side elevation and front end elevation, a rowing machine for physical training in accordance with the invention.

In carrying the invention into effect in one convenient manner, as shown in FIGURES 1 and 2 of the aforesaid drawings, a rowing machine for physical training comprises a base formed with a fore-and-aft strip 1 having a crosspiece 2 at each end. On opposite sides of the strip 1 are secured upstanding brackets 3 between the upper ends of which is pivoted a rocking beam formed of a rear arm 4, e.g., of wood, to the sides of which are secured two parallel metal strips 5 extending forward in alignment with the arm 4. A lever 6 is inserted between the strips 5, and a pivot pin 7 extends through the brackets 3, the strips 5 and lever 6. The lever 6 and the beam 4, 5 are thus independently pivoted on the common pin 7.

A cable 8 is connected at one end to a cross-piece between the free ends of the strips 5 of the beam, and at its other end to a cross-piece in a slot in the lower end of the lever 6. The cable 8 runs over pulleys 9, 10 mounted on the base 1, respectively substantially beneath the ends of the beam 4, 5 and the lever 6. The length of the cable 8 between the ends of the beam and lever may be adjustable. To the rear, free, end of the beam 4 is mounted an adjustable seat 11, and at the upper, free, end of the ice lever 6 is fitted a cross-bar 12 with handgrips 13 at the ends. It will be apparent that if an operator sitting on the seat 11 grips the hand bar 12, 13 and pulls it towards him, the lever 6 is rocked and causes the beam 4, 5 to rock, against the load provided by the operators weight on the seat 11.

A cross-bar 14 with a footrest 15 at each end extends transversely through slots 16 in the metal strips 5, and is slidable fore-and-aft there-in. Tension springs 17, one on each side of the beam 4, 5 extend between the crossbar 14 and fixed anchors 18 on the beam, tending to draw the cross-bar 14 to the rear ends of the slots 16.

In using the equipment described above an operator seats himself on the seat 11 with his feet on the rests 15, and grips the handles 13 to draw them towards him, in the manner of a rowing operation. At the same time straightening of his legs displaces the cross-bar 4 and extends the springs 17. In an alternative construction the cross-bar 14 may be fixed in the beam 4, 5, and the seat 11 be slidable along the arm 4 with spring means to locate it in a normal position. When the operator rows with the grips 13 and lever 6 the beam 4, 5, is rocked, as previously described, and the load against which the lever 6 is pulled is determined mainly by the operators weight on the seat 11. It will be noted that since this load depends on the users weight, the device is automatically suitable for use by persons of any size and age, since, for example, children will have less load to row against than adults.

From the above description it will be seen that the invention provides a simple and eliective rowing machine for physical training, but it should be understood that the invention is not limited solely to the details of the forms described above, which may be modified, in order to meet various conditions and requirements encountered, without departing from the scope of the invention.

What We claim is:

1. Physical training equipment comprising a base member, supporting means upstanding from said base member, a beam pivoted to said supporting means at a point intermediate of its ends, a seat on said beam on one side of said beam pivot, and means for connecting a flexible line to a point of the beam on the side of said beam pivot opposite to said seat, a lever also pivoted to said supporting means at a point intermediate of its ends, a handle adjacent to one end of said lever, means for connecting a flexible line to a point of said lever on the side of the lever pivot opposite to said handle, pulley means on said base member, and a flexible line running in said pulleys connected at its ends respectively to the said means on said beam and said lever for connection of a flexible line there- 2. Physical training equipment according to claim 1 wherein said supporting means comprises spaced supports, and wherein the beam and the lever are mounted on a common pivot pinextending between the supports.

3. Physical training equipment according to claim 1 wherein the beam and lever are mounted for rocking about a common pivot, and one passes through a slot in the other at the pivot point.

4. Physical training equipment according to claim 1, comprising a foot rest on one of the pivoted members, to receive the feet of an operator mounted on the beam seat.

5. Physical training equipment according to claim 1 wherein the lever handle is formed by a transverse hand grip secured to the lever near to one end thereof.

6. Physical training equipment according to claim 1 comprising a foot-rest slidably mounted on one of the pivoted members, and spring means attached to the footrest adapted to be extended under footpressure of an operator carrying out a rowing exercise on the equipment.
