DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be used, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, may be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.

The handle of the disclosure provides a system for exercising with linear components, such as resistance tubing, while providing efficient interchangeability options. Such linear accessories may be interchangeable so that only one set of handles is required. The user can change between different sizes and weights of resistance tubing to perform multiple exercises.

The handle of the disclosure securely holds linear components. During use, as axial force increases on the linear component, the linear component is drawn tighter within the handles, to provide for a safe exercise system.

FIG. 1 is a perspective view of an exemplary exercise system 100, including two handle assemblies 101 and one accessory 500, such as a resistance band, the opposed ends of which are secured between handle assemblies 101.

FIG. 2 is an exemplary handle assembly 101, having a casing or housing 110 and a handgrip portion 130 attached to housing 110. Housing 110 is shown as generally rectangular, but may be an alternate shape. Handgrip portion 130 may be a length of nylon strap or webbing 131 looped around an opposed pair of eyelets 108 extending from opposed lateral sides of housing 110, where each end is looped through the eyelet 108 sewn to itself with stitches 134 and/or bonded with adhesives.

As shown in FIG. 3, the nylon webbing 131 may be threaded through a cushioned, tubular handgrip 136 and reinforcements 132 may be provided around the nylon webbing to protect the nylon webbing 131 from edge wear from the tubular handgrip 136. Handgrip 136 may be plastic, and may be encased in foam or rubber.

As shown in FIGS. 4 and 5, housing 110 includes a pair of accessory capturing blocks that may be in the form of wedges 112 nested adjacently in housing 110. Housing 110 is generally open at the grip end (top as shown in FIGS. 4 and 5) and accessory end (the bottom as shown in FIGS. 4 and 5), and extends slightly beyond each side of wedges 112 to form the eyelets 108 for attaching nylon webbing 131. For the purpose of discussion, a y-axis extends from the accessory end to the grip end and generally axially with respect to the accessory, the x axis extends laterally across the housing 110 from eyelet 108 to eyelet 108, and the z-axis extends in the opposed lateral sides of the housing 110 perpendicular to the sides carrying the eyelets 108. The wedges 112 are generally movable along the x and y axes along a respective pair of slanted lines, L1 and L2, originating at the y-axis (below the x-axis) and angled outwardly in opposite x-directions and in the positive y-direction.

The slanted lines of movement L1, L2 for the wedges 112 may be provided by corresponding slanted outer surfaces 103 of wedges 112 that slide along correspondingly slanted tracks or ramp surfaces 102 of housing 110. Each wedge includes a semi-conical shaped surface 121 opposing the slanted outer surface 103, and the wedges 112 are oriented in the housing 110 such that the semi-conical shaped surfaces 121 face each other. The slanted outer surfaces 103 of the wedges 112 in cooperation of the correspondingly slanted ramp surfaces 102 of the housing allow the wedges 112 to slide within the housing to at least a pair of positions.

In a first position illustrated in FIG. 4, which is an accessory securing position (or closed position), wedges 112 meet approximate the z-axis so that the opposed semi-conical shaped surface 121 of the wedges meet to jointly create a funnel-shaped channel 120 for receiving an accessory, the funnel-shaped channel also herein referred to as accessory holder 120. Wedges 112 may be locked to housing 110 in the first position by a mechanical engagement of biased flanges 130 and extending from tabs 114 against a bottom surface (not shown) of ramp 102 within the housing. Manual manipulation of tabs 114 may overcome the bias to release the flanges 130 from the bottom surface of the ramp 102 to that the wedges may be lifted to the second (or open) position as will be discussed below. As will be apparent to those of ordinary skill, wedges 112 may be releasably locked to housing 110 by any suitable locking means, including locking tabs, latches, spring-loaded balls or pins. Housing 110 and wedges 112 may be molded from plastic.

When unlocked, wedges 112 slide bi-directionally along ramp 102 in a generally up-and-down direction along lines L1 and L2 such that the distance between wedges 112 increases as the wedges slide up towards the grip end of housing 110, providing for the lateral separation of wedges 112. In alternate embodiments, wedges 112 may slide bi-directionally in generally lateral direction, or generally back-and-forth direction. In the current embodiment, a stopper 117 may contact flange 130 as it is sliding up the back side of ramp 102 to prevent wedges 112 from sliding completely out of housing 110.

As discussed above, the opposed semi-conical shaped surfaces 121 of the wedges meet in the first accessory securing position to form a funnel-shaped channel 120, which has a diameter that decreases from the grip end of the housing to the accessory end of the housing. FIG. 6 is a view from the grip end of the housing 110, and shows an example relative diameter A of the funnel-shaped channel 120 approximate the grip end of the housing and diameter B of the funnel-shaped channel 120 approximate the accessory end of the funnel-shaped channel 120.

FIG. 7 illustrates one end of an exemplary accessory 500 including a linear portion 501, such as a resistance tube, having a fixed, conical shaped collar 502 the end. Fixed collar 502 may be made from a rigid or semi-rigid material and have an outer diameter C that is the major diameter and an inner diameter D that is the minor diameter of the conical shape. In an embodiment, the major and minor diameters C and D of the conical collar respectively correspond to diameters A and B of the funnel-shaped channel 120 (see FIG. 6). Linear portion 501 may include cord, elastic exercise cables, bands, webbing, rods, tubes, or any other linear shape part. The opposed end of the accessory not shown in FIG. 7 will have a matching fixed collar 502.

FIG. 8 and FIG. 9 shows the process of attaching accessory 500 to handle 101. By unlocking wedges 112 from housing 110 as described above, wedges 112 may slide along ramps 102 of housing 110 as described above, to a second, open position shown in FIG. 8, providing a gap 802 between wedges 112. In the second, open position the minor diameter of the funnel shaped channel 120 formed by the opposed semi-conical shaped surfaces 121 is now larger than the major diameter C of the accessory collar 502, so that the accessory collar may pass freely through the channel 120 and may be removed from or inserted into the handle 101.

Wedges 112 may be moved back to the first position within housing 110, to close gap 802 and capture collar 502 within accessory holder 120, as shown in FIG. 9. While diameters C and D corresponds to diameters A and B, major diameter C of collar 502 is generally larger than minor diameter B of the funnel shaped channel 120 in the first, closed position, to prevent accessory 500 from pulling through handle 101 in this position. When exercise system 100 is in use, the force is applied to accessory 500 is such that diameter C is forced towards the smaller diameter B, wedging conical shaped collar 502 tightly within the funnel shaped channel 120 of the handle 101. Using this concept, a tug may be given to accessory 500 to secure it within handle 101.

FIG. 10 shows an alternate handle 701 assembly with side rails 732 attached to sides 708 of housing 710, and extending beyond the top of housing 710. A rod 737 may bridge side rails 732, and thread handgrip 730 may be carried on the rod. Side rails 732 may be plastic, the rigidity maintaining a stable distance between handgrip 730 and housing 710. Rod 737 may be rectangular to prevent rotation of handgrip 736.

In an alternate embodiment, the system of the disclosure may simultaneously accommodate more than one accessory. As shown in FIG. 11 and FIG. 12, handle 801 includes three accessory holders 820, 822, and 824. In other embodiments a different number of accessory holders may be used, such as two or four accessory holders. In this embodiment, wedges 812 meet along the x-axis as shown in the axis diagram by FIG. 12 so that both wedges 812 include at least a portion of each accessory slot 820, 822, and 824. This configuration minimizes the number of parts and complexity, maximizing integrity and strength of the handle 701. Accessory slots 820, 822, 824 may be the same size for universal interchangeability. Accessory 500 collars 502 may be the same size, and linear components 501 may be varying material, elasticity, or length. In other embodiments, accessory holders 820, 822, and 824 may be different sizes.

FIG. 13 is an exploded view of housing 810 and wedges 812. Accessory holders 820, 822, 824 maintain the conical taper as discussed above. Four latches 814 lock wedges 812 to housing 810 at the bottom surface 813 of housing 812, where each wedge 812 has two latches 814, one on each end. Each latch 814 includes a flange 830 biased inwardly (towards the housing by spring arm 832) to slide in a corresponding groove 831 provided on the outer surface of the housing 810. When the flange 830 passes below the bottom surface (when the wedge 812 is in the first, closed, position) of the housing 810 the inward bias causes the flange 830 to secure onto the bottom surface 813. To unlock the wedge from the first position, the flange 830 may be pulled away from the bottom surface 813, overcoming the bias. As described in the embodiment above, wedges 812 have a first closed and a second open position. Protuberance 815 is provided in the groove 821 to act as a stop to limit movement of the flange 831 from passing above the protuberance. Consequently, when the wedge 812 is lifted until the protuberance stops further upward movement of the wedge 812, the wedge 812 is in its second open position.

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. For example, it is within the scope of the disclosure that only one of the wedges are moveable to create the widening/narrowing diameter of the funnel shaped channel. Additionally, it is within the scope of the disclosure that the accessory holders can have alternate shapes other than the funnel/conical shapes disclosed and illustrated herein. For example, the holders can be semi-spherical in shape (and the accessory collars may have a corresponding semi-spherical shape). It is also within the scope of the disclosure that other shapes for the holders and collars may be used, so long as the holder channel has an adjustable minor diameter (or minimum width—the channel need not be circular) that is sized to lock the collar of the accessory in place in a closed position, and adjustable to a larger diameter (or larger width) than the major diameter of the collar (or major width of the collar) to allow the collar pass by the holder in an open position.

The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
