FREE WEIGHT HARNESS SYSTEM

Abstract

A support assembly and exercise system provides safe and unconstrained movement of free weights within a movement zone encompassing normal travel of the free weights during exercise. The system allows safe user engagement and disengagement with the free weights while continually tethered against uncontrolled and possibly harmful movement. The support assembly is defined by a generally free-standing frame with rigid uprights for supporting takeoff and landing zones for the free weights, as well as tether attachments for movably supporting the free weights through the movement zone. A support member has a pivotal attachment to the upright frame for suspending the free weights against an uncontrolled release or fall. Launch and landing platforms attach to the upright frame for ideal positioning of the free weights prior to and following a usage session (workout).

DETAILED DESCRIPTION

[0020] The description below presents an example of the upright frame and safety tethers in conjunction with free weights for preventing a free fall of a dropped or mishandled weight, typically a dumbbell. The restraint mechanism is applicable to a variety of configurations of resistance objects including weights and other potential or stored energy exercise members, such as elastic strands and spring or coil loaded approaches that invite physical exertion against a stored force.

[0021] FIG. 1 is a front perspective view on an exercise environment and apparatus suitable for use with configurations herein. Referring to FIG. 1, a tethered attachment defines a non-restrictive region around a movement zone of a normal exercise and workout routine, and engages the free weight if dropped or uncontrollably disposed outside the movement zone. The tethers engage the weights through a releasable engagement such as that disclosed in copending application Ser. No. 17/460,621, filed Aug. 30, 2021, entitled “EXERCISE WEIGHT SAFETY HARNESS AND CLAMP,” incorporated herein by reference in entirety.

[0022] In particular configurations, the system includes a free weight support and restraint safety apparatus 100, including a tether 102 engaged with an upright frame 110 for securing a free weight 104 against unintended release and droppage, and an attachment 106 for securing the tether to the free weight. A pivoting support member 120 (support member) is adapted for lateral movement in a movement zone, in which the movement zone is defined by a volume of controlled manipulation of the free weight for intended use. A linkage between the tether and the pivoting support member is adapted to pivotally dispose the tethered free weight proximally and distally around the movement zone for user engagement and disengagement with the free weight 104.

[0023] The pivoting tether allows ingress and egress to the movement zone by the user, and is adapted to bear the mass of the free weight 104 through the pivoting range. Typically it takes the form of a pair of longitudinal bars extending from a rotational bearing on one end, with a protrusion or hook on the other. The tethers 102 drape over the longitudinal bar and are secured by the protrusion or hook. The longitudinal bars (support members) are therefore allowed to pivot outward as needed to accommodate user movement, and pivot inward until substantially parallel and aligned with the user. A bench or seat 125 accommodates the user during lifting.

[0024] The linkage of the free weights therefore includes a tethered loop 108 around the pivoting support member 120 and the protrusion 112 at an end of the pivoting support member. Under tension, the tethers 102 may slide axially along the support members and as permitted by the pivotal outward motion, providing a large movement zone while still tethered in the event of droppage, while the protrusion 112 prevents the tethers from sliding off the end of the pivoting support member 120.

[0025] FIGS. 2A-2C are schematic views of a front elevation, plan and side elevation views, respectively, of the apparatus of FIG. 1. In the free weight harness system 100, a plurality of upright members 111-1 . . . 111-4 (111 generally) define the upright frame 110, such that the upright members are disposed vertically for supporting at least one of the pivoting support members 120. Typically, for a free standing approach, four upright members 111 define a full frame, and the two pivoting support members 120-1 . . . 120-2 (120 generally) attach to a horizontal bar, crossmember 113′ or support across two of the upright members 111.

[0026] The upright members 111 are rigid metal load-bearing structures, and join with horizontal crossmembers 113 where needed for stability, such as a launch platform 150, side platform (discussed below), and horizontal support 113′ for the pivoting support members 120. Other suitable frames may be envisioned the pivotal attachments 122-1 . . . 122-2 (122 generally) define a movement zone 101 based on a sweeping arc 124 of the support member in a plane perpendicular to the uprights and based on a length of the tethered attachment in a region below the sweeping arc. In other words, the free weights 104 may be manipulated within the range or radius of the tether 102, and further by pivoting the support members 120 outwards. Generally, the support members are intended to be fixed in a parallel position during use, and pivot outwards to allow free weight placement on a side tray.

[0027] FIG. 3 is a front perspective view with the support members pivoted outwards as in FIG. 2B. Referring to FIGS. 1-3, a typical exercise routine commences with weights in a launch position, where the user may proceed directly to resistance movement with the weights, and ends with a landing zone, ideally near the end of a cyclic pattern so that a possibly exhausted arm need not further manipulate the free weight very far. Accordingly, the frame 10 includes a launch platform 150 removably engaging the upright members. The launch platform is engaged in an interference fit with horizontal protrusions such as pegs extending from the engaged upright members, and is adapted to support the free weight in an accessible position. A typical launch platform 150 is disposed in front of the user just below the pivoting support members 120 so that the tethers 102 loop around the support members 120 with ample slack for movement within the movement zone 101. A particular feature includes a facilitated mounting for the launch platform. In operation, a user need only slide one end of the crossmember 113 into a horizontal recess, as with the support members crossbar 113′ and then allow the other end drop onto the opposing protrusions (on the opposing upright 111) via the vertical recess.

[0028] A landing zone 140 is provided by a side platform adapted to engage the frame 110, and is disposed for receiving and bearing the free weight within range of the tether. The side platform is defined by a longitudinal surface adapted to extend between opposed upright members of the frame, in which the longitudinal surface has a detachable engagement with a respective upright member at each opposed end. In a particular configuration, the landing zone extends along a side perpendicular to the horizontal support for the pivots and parallel to the ground for floor, thus disposed on right and left sides between front and rear uprights in a frame with four uprights.

[0029] In a particular configuration, the tethers 102 engage the free weights as disclosed in the copending application cited above. Therefore, the attachment for securing the tether to the free weight further includes opposed clips adapted for attachment to a handle of a free weight, such that the clips have a spacing for engaging the handle at locations flanking a grip region of the handle. A receptacle on the clips receives the handle of the free weight, the tether attaches to the opposed clips, and a restraint secures the clip to the handle, such that the restraint has a spring loaded actuator for biasing the restraint in a secured position. This complements the support members by ensuring that the free weight cannot disengage from the tether 102.

[0030] FIG. 4 is a perspective view of crossmember for the pivotal attachment as shown in FIGS. 1-3. Referring to FIGS. 1-4, the support members 120 extend from a crossmember 113′ having opposed ends 115 including a receptacle having a horizontal opening 117 and a receptacle having a vertical opening 119 for engagement with protrusions 130 on the respective upright members 111.

[0031] FIG. 5 shows the support members 120 adapted to engage the crossmember 113′ of FIG. 4 to form the pivotal attachment 122. Each pivotal attachment has a receptacle 128 for receiving a shaft 126 at a proximate end 132 of the support member 120. The pivotal attachment also has a spring-loaded locking pin 136 for engaging a locking aperture 135 on the respective support member 120. When locked, the support members are parallel for use with tethered free weights. The pivotal attachment 122 with the shaft 126 fulling inserted is sufficiently rigid to avoid force or rotation imposed by a dropped free weight. The protrusions 112 on the distal end 134 retain the tethers 102 from sliding off the distal end 134.

[0032] FIG. 6 shows the pivotal attachment of FIGS. 4 and 5. Referring to FIGS. 1-5, the pivotal attachment further includes the vertical shaft 126 at the proximate end 132 of the support member 120, and the receptacle 128 on the crossmember 113′ attaches to the upright frame for receiving the vertical shaft 126. An intermediate support 142 engages the support member 120 along a longitudinal side just before the locking aperture 135 for accommodating downward forces from the tethered attachment imposed towards the distal end 134 of the support member, as in the case of a dropped free weight. The intermediate support 142 provides a bearing surface from absorbing the load from the dropped free weight. This provides for a torque limiting engagement from an interference fit with the intermediate support. Otherwise, the entire force of a dropped weight would tend to impose a forward, leveraged rotation on the receptacle 128. The transverse orientation of the intermediate support addresses pivotal movement in a plane parallel to the movement and perpendicular to an axis of the pivot, meaning even if the support members are swung out as in FIG. 2B, the support member 120 still bears on the intermediate support 142.

[0033] A dropped free weight (or even a gently hanging free weight) imposes the corresponding mass on the support member 120 and tether 102. Accordingly, the support member has an annular outer surface 144 from a radiused cover. The curvature spreads any point load that could affect the tether 102 if it had a sharp or square corner.

[0034] FIG. 7 shows a receptacle of the pivotal attachment of FIG. 6. The side elevation of FIG. 7 shows that the receptacle 128 is defined by two axially aligned bearings 146-1 . . . 146-2 bolted onto a vertical plate attached to the crossmember 113′. The annular outer surface 144 of the radiused element 145 can be seen disposed on an upper side of the support member 120.

[0035] FIG. 8 shows an alternate configuration of the support members using a hinge. In the configuration of FIG. 8, the support members attach to the upright frame and extending horizontally over the exercise region using a hinge between the support member and the upright frame. The hinge is defined by a through hole 160 in the support member allowing pivotal communication with a hinge bar 164. A landing bar 166 at an opposed end of the support members 120′ has a slot 162 receiving the support member 120′ to define a closed position. Alternatively, the slot could be in the support member 120′ to engage the landing bar 166. The hinge has an open position and a closed position for disposing the support member in selective engagement with a tethered attachment to the free weight 104. The closed position engages the support member 120′ with the perpendicular crossmember or landing bar 166 for securing the tethered attachment, and the open position releases the tethered attachment be lifting the support member off the landing bar 166 and allowing the tether 102 to slide out. As with the pivot arm configuration of the support arm 120, the tethered attachment is a tethered loop attached to the free weight, such that the support member has a terminal (open) end when the hinge is in the open position and secures the tethered loop in an interference fit when the hinge is in the closed position.

[0036] FIG. 9 shows a schematic diagram of the hinge opening of FIG. 8. Referring to FIGS. 8 and 9, the landing bar 166 has a receptacle 162 adapted to receive and engage the support member 120′ as the hinge transitions from the open position to the closed position. The closed position supports a gravitational force of the free weight on both the hinge 164 and the crossmember via the tethered attachment.

[0037] FIG. 10 shows a crossmember in the upright frame of FIGS. 1-3 including a launch platform. The launch platform 150 is defined by one or more horizontal surfaces 170 attached between an opposed pair of the plurality of upright members 110, such that the horizontal surface 170 is within a movement region defined by a length of the tethers 102 and adapted for receiving the free weight 104. In a particular configuration, the horizontal surfaces 104 align with the distance of the opposed elements of the free weight 104. In operation, the launch platform 150 disposes the free weights 104 for commencement of an exercise routine.

[0038] FIG. 11 shows a perspective view of the launch platform of FIG. 10. The launch platform 150 attaches via a crossmember 113 similar to the pivot supports 122. Alternate configurations may alter the size and/or spacing of the horizontal surfaces 170.

[0039] FIG. 12 shows a side platform 140 engaging the upright frame of FIGS. 1-3. In a particular configuration, the side platform further comprises a wrap around attachment 172 extending from one end of the opposed ends for defining an interference fit with a surface of the respective upright 111. The wrap around forms at least a 90 degree bend for a square upright, or a semicircular shape for a circular upright, and need only contact the exterior surface 111′ surface without any need for a cross pin or protrusion 130. A lateral bar 174 supports the length of the side platform between two uprights 111.

[0040] FIG. 13 shows a side perspective view of the upright frame with the pivotal attachment of FIGS. 4-7, the launch platform of FIGS. 10-11 and the side platform of FIG. 12.

[0041] While the system and methods defined herein have been particularly shown and described with references to embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims.
