Description

Exercise device

Technical Field

The present invention relates to an exercise device.

Background

Free weight exercise devices such as barbells can be loaded with weight plates on both sides to increase resistance to exercises such as squats, hard pulls, shoulder rises, bends and the like. Common barbells are of the straight bar type and can be used for a variety of exercises. The straight barbell has many uses but is not desirable for all weight lifters. For inexperienced weight lifters or weight lifters with limited mobility, the use of a straight rod for hard pulling may interfere with the knee or lower leg, which may result in scratching or bruising. The straight barbell may also be difficult to load-for example, when placed high on a squat stand support.

Detailed Description

Fig. 1-3 depict various views of a modular split looped curved rod 100. The figures are depicted simultaneously and not all of the components of the modular pole 100 are depicted or labeled in each figure. Modular pole 100 may be used for a variety of weight or non-weight exercises. For example, with the handle unit 102, the modular pole 100 may be grasped thereby and used for trapezius shoulder shrugging, modified hard-pulling, farmer walking, hammer lifting, and the like. With the handle unit 102 removed, the pole 100 can rest on the user's shoulder and be used for squatting, bowing, and the like. Other exercises may be performed with or without additional weight. When used in deep squats, the column on which the weight plate is loaded may be lower from the ground, facilitating its handling.

The modular pole 100 includes a generally U-shaped pole 104, the pole 104 having two ends 106 and a central portion 108. The two end portions 106 may be orthogonal or substantially orthogonal to the central portion 108. The two ends 106 terminate in a joint 110, and the other components of the modular pole 100 are fixedly or removably secured to the joint 110. The joint 110 may include a frame structure 112, which frame structure 112 may be open or closed on a particular side thereof. In this example, each end 106 of the generally U-shaped bar 104 is individually welded to an upper portion of the frame 112, while the legs 114 are welded to side portions of the frame 112. A leg 114 extends downwardly from each joint 110. In this example, the legs 114 are also welded to the ends 106 of the generally U-shaped bar 104 for added stability. The sheet support post 116 is secured to the frame 112, in this case by a plurality of bolts 118 or other mechanical fasteners through a flange 119. In various examples, for fixedly securing to the frame structure 112, welding, brazing, industrial adhesives, bolts, or mechanical fasteners or other means for securing the connection may be utilized. The manner of connection may be selected as needed or desired for a particular application based on the proposed use, loading desired values, selected component materials, and the like.

The sheet support post 116 includes a nose end 118 and a fixed end 120 separated by a collar 122. The protruding end 118 is sized and configured such that the protruding end 118 is received within a standard weight stack (not shown) as is well known in the art. One or more weight plates may be slid over the nose 118 until the innermost weight plate abuts the collar 122. Before use of the modular pole 100, a locking collar (not shown) may be secured against the outermost weight plate, as in the prior art. A rest 121 is provided between the collar 122 and the flange 119, which rest 121 may be placed on a support structure such as a squat frame between exercises. In other examples, the intermediate portion 108 may be used to support the modular pole 100 on a squat frame. When supported at the central portion 108, the sheet support posts 116 are lower and easier to load.

In addition to the flange 119, the fixing end 120 further comprises a protruding portion 123, which protruding portion 123 may protrude into the frame 112 of the joint 110. As shown primarily in fig. 3, the portion of the leg 114 proximate the joint 110 defines an aperture 124 for receiving the fixed end 120 of the sheet support post 116. Thus, the sheet support columns 116 are supported at multiple locations to provide a secure connection for offsetting the weight applied to the sheet support columns 116 when heavily loading weight sheets. In addition to bolts 118 connecting flange 119 to frame 112, the multiple support locations distribute forces along ledge 123 to help prevent sheet support post 116 from twisting or bending.

Each leg 114 extends downwardly from its associated joint 110 and may be generally parallel to the end 106. The legs 114 terminate in feet 126, and the feet 126 may be flared to improve stability. When the modular pole 100 is supported on the foot 126, the length of the leg 114 raises the sheet support post 116 so that a weight sheet can be placed on the sheet support post 116 without further lifting the modular pole 100 off the floor on which it rests. The flared foot 126 may also include a durable resilient material 128, such as a rigid or semi-rigid rubber or plastic, secured to the foot to reduce impact when the modular pole 100 is dropped or otherwise lowered onto a floor. The durable resilient material 128 may also increase the width of the foot 126, further increasing stability.

The handle unit 102 may be detachable from the modular pole 100, which increases its utility, as described elsewhere herein. Certain components of the handle unit 102 are best depicted in fig. 3. The handle unit 102 includes a base 130, the base 130 having a first side 132 and a second side 134. Two flanges 136 project outwardly from the first side and are secured (e.g., by welding) to the ends of the base 130. In one example, the base 130 may be an elongated member that is bent at the ends to form the flange 136. In the depicted example, two handles 138 straddle the flange 136 and provide a location to grasp and lift the modular pole 100. The handles 138 may be arranged parallel or at a small angle. In other examples, a single handle may be used, but multiple handles may add utility by allowing the weightlifter to grip the most comfortable handle 138 or handles that facilitate their particular exercise.

The handle unit 102 is detachably secured to the modular pole 100 at a joint 110. The handle post 140 extends from the second side 134 of the base 130 and is sized to be received in the joint 110. More specifically, the handle post 140 may be inserted into the channel 142 defined by the projection 123 of the sheet support post 116. One or more anti-pivot pins 144 may also protrude from the second side 134 of the base 130 and be configured to be received in mating recesses 146 at the joint 110. In this case, the fitting recess 146 is formed in a portion of the leg portion 114 closest to the joint portion 110. Although three anti-pivot pins 144 are depicted, a greater or lesser number of anti-pivot pins may be used in a particular configuration. When engaged, the anti-pivot pin 144 helps prevent the handle unit 102 from pivoting or rotating relative to the modular pole 100.

The anti-pivot pin 144 also helps align the

receivers

146, 148 defined by the handlebar post 140 and the protruding portion 123, respectively. When aligned, the receiving

portions

146, 148 may receive a pin 150 that secures the handle unit 102 to the modular pole 100. The entire length of pin 150, or a portion thereof, may be threaded to receive a nut 152 to secure pin 150 in place. The pin 150 may include a head 154 that prevents over-insertion of the pin 150 into the

receivers

146, 148 and may grip when the nut 152 is tightened or loosened.
