The exercise apparatus is designed to more effectively work out the large muscle groups of the back and arms.

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Provisional Application No. 61/411,344, filed Nov. 8, 2010, which is hereby incorporated by reference.

BACKGROUND

The present disclosure generally relates to exercise devices, and more particularly, to upper body exercise apparatus. Some examples of upper body exercise apparatuses according to the present disclosure may be pull-up bars, push-up bars, shoulder presses.

SUMMARY

Pull-up bars with adjustable grips and/or mounts are generally disclosed. Some example embodiments may include methods, apparatus, and/or systems associated with such pull-up bars.
In some embodiments, the exercise device is a longitudinal bar, each half of the bar having a slot cut along a portion of its length. The slots are generally situated along one longitudinal side of the bar. One handle protrudes from each slot, and the handle is able to travel along the length of the slot. Rollers engage the handles onto the bar, and enable the handles to slide within the slot.
Each slot section may include one or more pin-receiving holes extending laterally through the bar for blocking some movement of the handle within the slot, When a selector pin is inserted through the hole, it prevents the handle from moving to a section beyond the selector pin. By blocking the movement of the handle within the slot, the handle is restricted to a portion of the slot to travel within. The selector pins may be retained to the apparatus by elastic cords attached to each of the distal ends of the track bar.
The exercise device may include one or more laterally extending connection bars attached laterally to one or more points along the bar for mounting to a stationary object, such as a wall, or modified to be placed over a door frame for pull-ups, or mounted on a floor, for push-ups. The connection bar(s) may also be coupled to a pulley system on an exercise apparatus to exercise alternate muscle groups, such as the deltoids in a shoulder press routine.
In some embodiments, the handles stay fixed within the same plane. In another embodiment, the first and second handle can rotate, or swivel, so the two handles may also lie in different planes. In a swiveling embodiment, a user may change his grip on the bar from overhand grip to hammer grip without taking his hands off the handles.
In some embodiments, the bar is generally rectangular. The bar may also be cylindrical, triangular, or another cross-sectional shape. In some embodiments, the bar is hollow. The bar may also be a solid bar with a track for the wheeled handle grips on the outside of the bar.
In some embodiments, the track bar contains slots. The track bar may be devoid of slots, and the handles may slide run on a track for example, in which case, a stopper such as a pin may be inserted laterally through the bar at the midpoint so each handle stays on its designated side of the track bar.

DETAILED DESCRIPTION

The present disclosure contemplates that some conventional pull-up bars do not allow the hands to move apart from or toward each other, or turn in any direction when performing a pull-up. When the hands grab a static bar during a pull-up exercise, a strictly vertical exercise must be performed, restricting motion and preventing the arm and back muscles from undergoing a full range of motion. The main focus of the latissimus dorsi, the largest muscle of the back, is to pull arms over the head and to the sides, or in front of the body. By performing pull-ups on a static bar, the latissimus dorsi cannot be fully exercised. By using the apparatus of the present disclosure, a wide range of motion is performed, and large muscle groups, including the latissimus dorsi, can be effectively exercised.
FIG. 1 shows the front view of exercise apparatus 10 in an exemplary embodiment, as it is attached to a wall. A longitudinal bar 12 has a first elongated slot 14 and a second elongated slot 18 on the one underside side 16 of the bar 12. Two handles 20 and 22 are engaged on the bar protruding from each slot 14 and 18, respectively, and are able to travel along a respective portion of the length of the bar 12 within slot 14 and 18. Bar 12 is bolted to laterally extending connection bars 24 with bolts 26 and mounted to a wall with vertical bracket arm 28 and horizontal bracket arm 30, the bracket arm 28 flush to the wall. One or more pin-receiving holes 40 extend laterally through the bar 12. Selector pins 45 are inserted into the desired pin-receiving holes to limit travel of handles 20 and 22. Optionally, hooks 47 may be installed in bar 12, or in an alternate embodiment, prevent the movement of the handle past the midpoint of the bar.
FIG. 2 shows a second embodiment of exercise apparatus 10 which is adapted to attach over a door frame. Longitudinal bar 12 contains elongated slots 14 and 18 along the underside 16. Handles 20 and 22 protrude from slot 14 and 18 and are slidably engaged to the bar 12. Two laterally extending connection bars 24 attached to bar 12 connect to abutment bar 15 which is parallel to bar 12, and which abuts across a door frame to stabilize apparatus 10. Connection bars 24 are bent at an angle to attach to the door frame, and further connect to a mount piece 25 to secure bar 12 above the door frame. In this embodiment, handles 20 and 22 slide in the slots 14 and 16, but do not swing or swivel.
FIG. 3 shows a detailed view of an exemplary handle assembly 20 and 22. Handles 20 and 22 include a pair of rollers 50 to enable sliding of handles 20 and 22 along bar 12. The handles 20 and 22 attach to a clevis rod end 53 with a swiveled bolt 23 which allows the handle to swing. The clevis rod end 53 is then attached to a bearing 51 which allows the handle to swivel in a 360 direction on the wheel carriage 54. The bearing attaches the handles 20 and 22 to the wheel carriage 54 which holds the rollers 50. Handles 20 and 22 may have a padded grip 27.
FIG. 4 shows the longitudinal bar 12 of the pull-up apparatus 10. Slots 14 and 16 are shown cut in their respective segments on bar 12, located on the underside 16 of bar 12. Bolts 26 are located toward each distal end where the bar is attached to the connection bar. Two pins 47 divide the bar into segments, or in an alternate embodiment, contain each handle 20 and 22 in its respective side of the bar 12.
FIG. 5 shows an embodiment of the pull-up apparatus as it would be mounted over a door frame. Attachment points to the curved connection bars 24 are located towards the center of the bar so bar 12 can extend beyond the width of the door frame while connecting to abutment bar 15 and mount 25 located on the other side of the door frame with respect to bar 12. Abutment bar 15 contains two padded sleeves 46 on either end to press abutment bar 15 against the door frame without damaging the door frame. Mount 25 hooks over the door frame to support a portion of the load, the load made up from the exercise apparatus itself and the weight of the person using the exercise apparatus. The load is further distributed on the abutment bar 15 against the door with abutment bar 15 acting as a fulcrum. Mount 25 stays securely on the door frame because the weight of the exercise apparatus on the other side of the door frame pushes it into the wall while abutment bar 15 prevents the apparatus 10 from swinging through the door. Using this load distribution, exercise apparatus 10 is installed to a typical door frame, without tools, quickly, and without permanent damage to the door frame.
The frame of the apparatus including bar 12 is made of a rigid material, such as a metal or metal alloy. The rollers 50 may alternately be ball bearings. The handles 20 and 22 may be made from a rigid, semi-rigid, or flexible material. The connection bars 24 may be made from a rigid material for some embodiments, or a flexible material such as rope, for mounting apparatus 10 to a ceiling.
To use this apparatus to engage in pull-up exercises, a user holds one handle in each fist, keeping both arms straight. The two handles should be relatively close together. As the user performs a pull-up by bending both arms at the elbow at the same rate, the distance between the handles should increase. Once the user reaches a maximum bent arm position, the user begins to straighten both arms at the same rate, at the same time decreasing the distance between the handles until the arms are straight and hands are in the starting position. This completes one cycle of a pull-up performed on the apparatus.
As a push-up or shoulder press apparatus, the initial position is bent arms and in a maximum separation distance between the handles. The user pushes up straightening the arms, at the same time decreasing the distance between the handles, until both arms are generally straight. From a straight arm position, the user bends the arms at the same rate and increases the distance between the handles, returning to the initial bent arm position. This completes one push up, or shoulder press cycle.
