DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(11) Referring to FIGS. 1, 2 and 3, the main elements of the horizontal exercise rowing machine 10 are as follows:

(12) A base 100 to engage with the floor. The base is sufficiently large to provide stability to the machine. In the preferred embodiment, the base 100 comprises of two longitudinally extending base supports 101, one on the right and one on the left side of the base. The base supports 101 have a plurality of cross support beams, horizontally extending between the right and the left base supports 101. The first cross support beam 102 is attached close to the front end of the base support beams 101 to support a seat 110 and a chest pad 112 of the machine. A second cross beam 202 is provided at the rear end of the base support beams 101 to provide more stability to the machine.

(13) An adjustable seat 110 attached to a vertical seat support beam 103. The seat 110 can be adjusted upwards and downwards, according to the user's height, using pinholes 105 mounted on the vertical seat support beam 103. The vertical seat support beam 103 connects to a vertical chest support beam 104 through a cross beam 106 having pinholes mounted thereon to provide forwards and backwards adjustability to the seat. In addition, the seat 110 can be removed to operate the machine in a standing position.

(14) An adjustable chest pad 112 to help prevent the upper body from moving forward and taking tension off of the upper back muscles. The chest pad 112 helps to create an ergonomically friendly lever, which allows an effective rowing motion. Said chest pad 112 is mounted from one end to the L shape vertical chest support beam 104 and to the horizontal support beam 102 of the main frame 100 from its other end. The L shape chest support beam 104 further has pinholes 107, 109 to adjust the chest pad 112 according to the user's height. The vertical chest support beam 104 connects to the middle support beam 127 through a cross beam 128. The chest pad further has 112 swivel means 108 to change its angle during the exercise and can be removed to operate the machine without a chest pad 112.

(15) In a conventional rowing exercise, the reaction force during the pulling action is taken by the user's legs, which are fixed on a pair of foot pads. This is possible because the conventional rowing exercise is performed in a horizontal direction. In the present machine, the legs can be in any desired plane and not necessarily in the same horizontal plane as the hands. Therefore, during the pulling action, the reaction force may not be as effectively transferred to the legs. A chest pad 112 allows said force to be transferred to the user's chest. This provides a comfortable rowing exercise and supports user's upper body when it presses against it.

(16) A moving portion comprising of a pair of handles (113a-113h) is attached to a pair of moving arms 120 extended to a pair of weight plate holders 121 on each side and a pair of support arms 124. Said support arms 124 are rotatable and moveable about an axis point 129 and connected to the middle support beam 127 of the frame. Generally, the two moving arms 120 move independent of each other. This allows the user to easily operate the machine 10 to exercise a muscle group on either the left or the right side of the body. Furthermore, this independent motion will insure that each arm of the user is performing the exercise, to improve the overall results and prevent a stronger arm from overly compensating for the other. In addition, the total weight being lifted is split evenly between the arms. The handles (113a-113h) are arranged in a manner to be grasped by the user and moved along a guided path resisted by the machine 10.

(17) In order to effectively manipulate the moving arms 120, each moving arm 120 is provided with at least a handle (113a-113h) with a unique shape that provides 8 grip position and at least 6 points to connect a swivel handle 114 that the user will grip when performing the exercise. Therefore, the range of motion of various handle positions will define various upper body muscle workout when performing the exercise.

(18) According to FIG. 3, each handle (113a-113h) is extended to a weight plate holder 121 by a support arm 120. Each weight plate holder 121 allows adding resistance to the machine. The machine 10 can be loaded with multiplicity of plates 122. In one embodiment, the device 10 can be loaded with up to eight 45 pound plates per side or per handle. Therefore, it can be used for training purposes for athletics or body building.

(19) As shown in FIG. 4, the handles (113a-113h) are provided in a specific shape that can be held in at least 8 different fixed positions 113a, 113b, 113c, 113d, 113e, 113f, 113g and 113h. In one embodiment, each of the two handles (113a-113h) have a plurality of apertures at 6 different positions 115a, 115b, 115c, 115d, 115e and 115f. Swivel handles 114 can be mounted and fixed to the handle apertures (115a-115f) to maintain a comfortable grip during the exercise. The user's grip can easily change during the exercise when the swivel handles are moved forwards, backwards, or slightly leftwards and rightwards to create the rowing action.

(20) The moving arms of the machine 120 are connected to the weight plate holders 121 in a manner allowing them to move upwardly by user's pulling action. The position of applied force can be changed by changing the position of the grip on the handles (113a-113h). This allows the user to work out the desired muscles.

(21) The user can make this exercise more challenging by using resistant bands. According to FIGS. 1 and 2, again at least a pair of band hooks 123 is provided on each of the support arms of the handle 124 for adding more weight to the exercise. This enables the user to workout with resistance bands alone when pulling on the handles (113a-113h), which will provide dynamic resistance that is exponential in nature. Further, this elastic resistance may be used in combination with weight plates 122. Adding the elastic bands allows for maximal muscular contraction throughout the entire range of each repetition.

(22) The present invention includes foot plates 116, 117 to provide a foot receiving surface. The foot plates are arranged so that the user can also operate the machine while standing and with the right foot or the left foot thereon. One pair of foot plates 116 are mounted with an angle on the outer support beams of the frame 126 to enable the user to perform the machine with either the right or the left foot. The second pair of foot plates 117 is mounted with an angle on the middle support beam of the frame 127 to enable the user to perform the machine with both feet. The user can operate the rowing exercise only with the right or the left hand, or with the right or the left foot, or with both hands and feet. The user can also operate the machine in a seated position or standing position by removing the seat.

(23) In order to perform a rowing exercise using the present invention, the user can be seated on the seat, with both feet resting on the foot plates while holding the handles securely. As the handles are pulled back, simultaneously or one at a time, the moving arms rotate around the axis point facilitating the weight plates (resistance) to move by the force created by the user. The resistance 122 moves from a rest position upwardly against the gravity to an upper position. When the user has completed the lifting stroke, the resistance returns to its rest position.

(24) Different methods of operation of the machine are shown in FIGS. 5A, 5B and 6A, 6B. In one method, the user sits on the seat 110 facing forward and grabs the handles (113a-113h) or the swivel handles 114. Then, the user places his/her feet on the foot plate 117, and pulls the handles toward his/her body, while leaning on the chest pad 112. The user can change the grip position to train different muscles. During the pulling action, the upper back and arm muscles are primarily used to pull the handles 114 toward the user's chest. The angles of elbows are naturally changed to pull up the weight plates 122. This state is maintained for several seconds after the pulling operation to allow the muscles to be sufficiently contracted. Then, the force is lowered and the weights plates are moved back to their original resting position. The user's grip can easily change dynamically when the swivel handles are moved forward, backward, or slightly leftward and rightward to create the rowing action.

(25) The rowing operations are repeatedly carried out creating the stimulus to obtain the desired muscular adaptation from this rowing exercise. Through the above-mentioned exercise, the user can build his/her upper body muscles, especially, the muscles of the upper back and front of the arms. The handles (113a-113h) are arranged in a manner to be grasped by the user and moved along a guided path resisted by the machine 10. Since the chest pad has a swivel mechanism, the upper body of the user can rotate in various angles while performing the exercise.

(26) In another embodiment, the seat can be removed to perform the rowing exercise while standing. The user can perform the exercise while standing with the right foot on the foot plate 116 and pull the right handle (113a-113h) or swivel handle. The user can also perform the exercise while standing with the left foot on the foot plate on the left side of the rowing machine while holding the left side handle.

(27) The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

(28) With respect to the above description, it is to be realized that the optimum relationships for the parts of the invention in regards to size, shape, form, materials, function and manner of operation, assembly and use are deemed readily apparent and obvious to those skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
