Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This utility patent application filed under 35 USC §111 claims priority to U.S. provisional patent application 61/759,900 filed on Feb. 1, 2013, which is incorporated herein by reference.

TECHNICAL FIELD

The device relates to exercise and fitness products and more particularly to upper body fitness.

BACKGROUND

Exercise equipment is frequently used to develop strength in the upper body, including the wrists and forearms. This equipment includes weights suspended from ropes, compression exercisers such as springs or other resilient materials that can be squeezed in a user's hand, and small bar bells. Much of this equipment is not easily portable.
There are hand and wrist exercisers of the general type which include a pair of hand grips which are mounted generally coaxially to each other and which can be rotated relative to each other against a resistance force. These devices are more lightweight and portable. An exercise routine can be performed to develop forearm muscles by counter-rotating the hand grips against the resistance force. These devices also loosen and stretch the muscles and tendons of the wrists.
Many of these devices do not provide a way to vary the degree of resistance offered the rotation of the hand grips. Consequently, a device that may be suitable for use by one individual may provide resistance forces too large for others. But after a while, the exercise may become too easy.
These devices also typically do not allow exercises in more than one plane and do not allow exercises based on rotational movement.

DETAILED DESCRIPTION

Referring to FIG. 1, the exercise device 10 has a central case 15 and two handle assemblies 20. The handle assemblies 20 can be rotated and moved relative to the central case 15 so a user can develop strength, endurance and dexterity for the upper body, including strength in the hands, wrists and arms.
A friction case clutch 25 can be adjusted to vary the amount force needed to move the handle assemblies 20. For example, clockwise rotation of the friction case clutches 25 increases the amount of force necessary to move the handle assemblies 20 and counterclockwise rotation reduces the amount of force necessary to move the handle assemblies.
A display panel 30 can be used to track various exercise and fitness parameters and to prompt a user to perform a certain exercise routine.
Referring to FIGS. 2 and 3 the central case 15 has a cylindrical shape with interior and exterior threaded portions 35, 40.
A friction element case 45 with a threaded end 50 is secured to the central case 15 by fixing the threaded end 50 to the interior threaded portion 35. The friction element case has a cylindrical shape with a tapered end 50. The friction element case may be made of metal or another type of conductive material.
A friction ball 55 and a friction element 60 are positioned inside the friction element case. The friction element 60 may be a rubber pad that is compressed against the friction ball 55 thereby causing some resistance to the rotation of the friction ball 55. As mentioned above, the friction case clutch 25 can be rotated in one direction to increase the compressive force between the friction element 60 and the friction ball 55 and in the opposite direction to decrease the compressive force between the friction element 60 and the friction ball 55.
An apron 63 is attached to the central case and covers the wide end of the friction case clutch 25. The apron 63 prevents damage to end of the friction case clutch 25 and protects the exterior threaded portion 40 of the central case 15.
A pressure sensor 65 is positioned between a wall 70 of the central case 15 and the friction element 60. Circular discs or spacers 75 are positioned on each side of the pressure sensor 65.
Referring to FIG. 4, a wire 80 connects the pressure sensor 65 to an electronics panel 85. Another wire 90 connects a sensor 95 in the handle assembly to the electronics panel 85. The sensor 95 can be used for measuring parameters such as user pulse rate. The electronics panel controls the functions of the display panel 30 and operation buttons (not shown). A battery 100 is positioned behind or underneath the electronics panel 85.
Referring to FIGS. 5A-5D, the handle assemblies 20 can be removed from the central case 15 with a tool 105 that loosens and tightens a clamp 110. The handle assemblies 20 are interchangeable to provide handles with various configurations for different training needs.
Referring to FIGS. 5B and 5C, a wire 115 attaches a sensor band 120 in the handle assembly 20 to a handle rod 125 that attaches to the friction ball 55.
Referring to FIG. 5D, the handle assembly 20 includes a handle base 130 that attaches to the handle rod 125. An interchangeable outer handle 135 is held in place by a handle lock 140.
FIG. 6 shows another embodiment of the exercise device. In the embodiment shown, there is no friction element case inside the friction case clutch 25. Instead, components such as the friction element 60 and the friction ball 55 are held in place by the friction case clutch 25. The embodiment shown in Fig. may or may not have an electronics panels and/or sensors to measure force needed to move the handles.
FIG. 7 shows a partial cut-away view of the exercise device. As shown, the friction ball 55 contacts the friction element 60 which has a circular cut-out to accommodate the shape of the friction ball 55.
FIGS. 8 and 9 are exploded views of the embodiments with shading to illustrate the components. FIG. 8 shows the first embodiment with the friction element case 45 enclosed by the friction case clutch 25. FIG. 9 shows the second embodiment without a friction element case 45. The second embodiment may or may not include items such as pressure sensors.
The variety of exercise routines that can be employed are very flexible based on the needs of the user. The basic initial positions for the exercise device are in front of the body, behind the back, over the head and to the side. Planes of motion of the exercise device can be horizontal, vertical-transversal, vertical-longitudinal and it can also be used in intermediate planes.
Main modes of gripping the handles are with the thumbs turned to the body of the exerciser, with the thumbs turned from the body of the exerciser, and with one thumb turned toward and the other one turned away from the body of the exerciser.
In one of the exercises, the handles are rotated in a vertical plane up-down. The exercise can be performed with the initial position behind the back, overhead, and on the side. The device can be held at the waist, at the breast, at the head level and over the head. Movements can be performed in different planes including horizontal, vertical-transversal and intermediate planes. The exercises may differ in the way the handles are gripped, such as, for example, with thumbs turned to or from the body of the exerciser, with one thumb to and the other away from the body of the exerciser.
The following is a list of exemplary exercises:

- 1. Move the exerciser upwards simultaneously rotating the handles downwards. Get back to the initial position in reverse order.
- 2. Rotate the handles of the exerciser onwards in a horizontal plane; simultaneously bring the elbows to the front and then backwards.
- 3. Rotate the handles of the exerciser onwards in a horizontal plane; simultaneously bring the elbows to the utmost in front of yourself and then backwards to the farthest point behind the back.
- 4. Rotate the handles of the exerciser in a vertical plane upwards with elbows up and down to the farthest points.
- 5. With one hand gripping the exerciser's body and the other grasping the handle, rotate the handle in all possible directions.
- 6. Rotate the handles along their longitudinal axes, perform movements simulating twisting a wet cloth. Get back to the initial position in a reverse order.
- 7. With one of the handles firmly fixed to the user's body, rotate the other handle around and backwards behind the back together with the exerciser's body, while simultaneously moving the elbows in the same directions.
- 8. Move the upper handle downwards and the lower handle upwards in parallel directions.
- 9. With one of the handles firmly fixed to the body, move the other handle to the right and left in parallel direction.
- 10. With one of the handles firmly fixed to the body move the other handle up and down, keeping them parallel.
- 11. With arms straightened, move the upper handle downwards and the lower handle upwards, keeping the handles parallel.
- 12. Move the handles in parallel planes simulating bicycle pedaling.
- 13. With one of the handles firmly fixed to the user's body, rotate the other handle simulating brace movement. The handles should remain parallel.
- 14. Perform a cone-shaped rotation of the handles simultaneously moving the exerciser's body onwards-backwards.
- 15. With thumbs against the exerciser's body, grip the handles with the four fingers of both hands and rotate them upwards; get back to the initial position rotating the exerciser along its longitudinal axis.
- 16. One hand holds the exerciser's body; the other hand with the thumb against the body grips the handle with one, two or three fingers. Rotate the handle upwards; get back to the initial position, rotating the exerciser along its longitudinal axis.
- 17. One hand holds the exerciser's body and the handle is located between the fingers of the other hand. While gripping the handle by the fingers rotate the handle in different directions.

To accumulate maximum muscle strength from the exerciser, the load offered should be high enough for the athlete to perform 6-12 repetitions of the exercise at a minimum possible rate. To develop power endurance, the number of repetitions should be 20 at a minimum. The load used throughout the exercise should leave the individual with muscle fatigue at the end of the exercise. This regimen can be applied to train the cardiovascular system along with strength training.
To increase speed and strength parameters, exercises should be repeated 6-15 times before upgrading to a higher resistance level. Before upping the resistance level, an individual must be able to rotate the handles at a fast pace at the current resistance setting. Athletes can perform 5-6 sets of every exercise, with 1-3 minute intervals of active rest in between sets.
Rapid progress in strength and endurance can be maximized with systematic use of the exercise device according to the program explained above. Since keeping tracking of training routines and progress results can be complex and time consuming, the on-board electronics panel can store the information so that the user does not have to manually log exercise routines and progress.
The information that is can be displayed and stored includes the amount of force needed to move the handles, the number of repetitions, the user workload, pulse, calories burned, etc. In one embodiment, the display on the exercise device generates a moving image of a person showing how to use the exercise device. In another embodiment, the electronics panel communicates by Bluetooth or other wireless technology to download workout information and to upload exercise routines.
