Description

Background of Invention

[0001] This invention relates to an exercise machine and more particularly an exercise machine that uses the principals of the Tug-of-war game.

1.Background

[0002] Tug-of-war is a game that can exercise all of the major muscles and muscle groups as well as provide a good cardiovascular workout.

[0003] The conventional tug-of-war game requires only a length of rope, a relatively even number of players and a large playing area. The rope is laid out such that its midpoint is centered over an identifiable finish line or object, leaving equal lengths or portions of rope on either side of the finish line. Contestants line up along the rope on each side of the finish line grasping the rope with its midpoint still centered. When the signal to begin the game is sounded, each side attempts to pull the other side over the finish side; when that is accomplished, the game is won, and over.

[0004] The problem with using Tug-of-war as an exercise is that you need a number of people to be an each team as well as a large playing field. A tug-of-war game can last from as short as 10 seconds to hours depending on the teams competing. This makes it hard to judge the length of exercise.

Detailed Description

[0014] The following description of an exercise machine is demonstrative in nature and is not intended to limit the scope of the invention or its application of uses.

[0015] There are a number of significant design features and improvements incorporated within the invention.

[0016] The current invention is an exercise machine that is based on the principles of the game of Tug of-war. It has a base with a sitting means with a fibre rope spliced into a single continuous length or loop attached to a resistance means. The resistance means is adjustable to increase or decrease the amount of resistance on the rope. The base will have foot rests allowing the user of the device good footing while pulling on the rope.
As shown in Figures 1. through 9, the exercise machine 1 has a base 10, a pulling means, a plurality of resistance means 20 and a seat 30. Figure 1 shows a front view of the exercise machine. Figure 2 shows the back view of the exercise machine. Figure 3 shows the back left side of the Exercise machine. Figure 4 shows the back right side of the exercise machine. Figure 5 shows the right side of the exercise machine. Figure 6 shows the left side of the exercise machine. Figure 7 shows the top view of the exercise machine. Figure 8 shows the front left side of the exercise machine. Figure 9 shows the front right side of the exercise machine.

[0017] The base 10 consists of the resistance platform 15, the seat bar 25 and the seat bar support beam 17.

[0018] The seat bar 25 connects the seat bar support beam 17 with the resistance platform 15. The scat bar 25 is perpendicular to the seat bar support beam 17 and is connected to it by seat bar connectors 18. These seat bar connectors 18 give the seat bar 25 height so that it is an optimal height for a work out and so that the seat bar 25 is level with the resistance platform 15.

[0019] The seat bar 25 is connected to the top of the resistance platform 15 and runs through the center of the resistance platform 15.

[0020] The resistance platform 15 is rectangular in shape in the preferred embodiment. The resistance frame 35 is attached to the top of and is perpendicular to the resistance platform 15. The resistance platform 15 holds the resistance means and the pulling means and consists of box frames.
The exercise machine 1 has a plurality of adjustable legs 40. These legs are attached to the bottom of the resistance platform 15 and the seat bar support beam 17. The adjustable legs 40 are screw type legs such as bolts which screw into the body 10 with each leg 40 being screwed in so it is the appropriate height so that the exercise machine 1 is level with the ground. This allows the leveling of the exercise machine 1 on an uneven surface. The legs 40 can have a soft felt or plastic cap on the bottom so not to damage the floor that the exercise machine 1 rests on.

[0021] The seat 30 rests on the top of the seat bar 25. The seat's 30 top is in a shape that a user of the exercise machine 1 can sit confirmable in and at the proper angle for pulling on the pulling means. On the bottom of the seat 30 there are two parallel extensions 31 which are at a distance apart that is slightly wider than the width of the seat bar 25 and connected at the bottom surrounding the seat bar 25 securing the seat 30 to the seat bar 25.

[0022] On one of the parallel extensions is the seat attachment means 32 which in the preferred embodiment is a handle with a cylinder bolt. The seat bar 25 has a plurality of seat position holes 26 which run through the seat bar 25. The seat attachment means run through one extension 31 through one of the seat position holes 26 and through the other extension 31. The user can adjust the seat 30 by moving it up and down the seat bar 25 so it is the proper distance from the pulling means to maximize their work out. While pulling on the rope 100, the user may fix the seat to the seat bar using this mechanism, or alternatively can allow the seat 30 to move forward and rearward along the seat bar 25 in the horizontal plane.

[0023] In the front of the resistance platform are two foot paddles 50. The foot paddles 50 are angled slightly away from the user with adjustable foot straps to hold the user's feet on the foot paddles during the pulling motion.

[0024] The pulling means in the preferred embodiment is a rope 100 of at least two inches diameter spliced into a single continuous length or loop. The rope 100 is of sufficient length to allow that part of the rope 100 returning to the resistance axle 70 to hang free of tension. The user pulls on the rope while sitting in the seat 30 with their feet firmly planted in the foot paddles using a pulling motion like that in tug-of-war. The user will pull on the rope 100 against the resistance means. As he does so, the free end of the rope loop then falls to the floor, and is coiled back onto the resistance axle 70 by the turning motion imparted to it by the user. The user can therefore pull on a rope that is, in effect, indefinitely long.

[0025] The rope ends are guided by two circular rope guides 65 through which the rope ends pass through. The rope guides 65 are made of a flexible material such as rubber or cloth. The rope guides 65 hold and guide the rope 100 as it is being pulled by the user. The rope guides 65 are held in place by the rope guide pole 66 which is connected to and runs perpendicular to the resistance platform.

[0026] The rope is wrapped around the resistance axle 70. The resistance axle 70 provides the resistance 70 to the rope 100. The resistance axle 70 is held up and runs through the platform frame 35 through an axis within each frame of the resistance platform frame 35. The axis is a standard axis which holds the resistance axle 70 to the frame while allowing it to turn with reduced friction. Figure 10 shows the rope connection.

[0027] In the preferred embodiment, there is a back rope guide 90 connected to the back rope guide pole 95. The back rope guide 90 guides the rope end that comes from the back of the resistance axle 70 to the front of the resistance platform 15. The rope end goes through the back rope guide 90 and up to the rope guide 65. The back rope guide pole 95 is connected to and runs perpendicular to the resistance platform 15.

[0028] On one side of the resistance axle 70 is the resistance flywheel 80. The resistance flywheel 80 provides the resistance through the resistance axle 70 to the rope 100 being pulled by the user.

[0029] A resistance applying means is used to apply resistance to the flywheel 80. In the preferred embodiment, the resistance applying means is a set of rods 85, one on each side of the top of flywheel 80. These rods 85 have fraction pads 86 that touch and apply friction to the flywheel 80 which produces the resistance. The rods 85 are attached to a tension adjustment means. The tension adjustment means can be a turn knob 105 which when turned tighter would wind two wires 97 that are each attached to one of the rods 85 bringing them closer together thereby increasing the friction on the flywheel 80 which will increase the resistance. When the knob is turned looser the rods 80 would spread apart reducing the friction and reducing the resistance. The turn knob 105 would run through the top of the frame.

[0030] In the preferred embodiment, the resistance platform 15, frame 35 and the seat bar 25 would be made of a strong durable material such as aluminum or steel.

[0031] To use the exercise machine, the user would adjust the resistance to what they wanted for a good workout. The user would adjust the seat for their body (or allow the seat to move along the seat bar, if preferred), sit in the seat 30, and put their feet in the feet paddles. They would then grip the rope 100 and pull on it using a tug-of-war pulling motion while planting their feet firmly in the foot paddles 50. They would do this until they get the proper muscle and cardiovascular workout that they were looking to get.

[0032] The exercise machine 1 could also be used as a training device for a tug-of-war sportsman.

[0033] In the preferred embodiment, a single rope 100 is used but a plurality of ropes could be used in an alternative embodiment.

[0034] Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the point and scope of the appended claims should not be limited to the description of the preferred versions contained herein.

[0035] As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

[0036] With respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one 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.

[0037] Therefore, 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.
