DETAILED DESCRIPTION

(9) Referring to FIG. 1, an exercise weight support device for enhancing the safety of lifting exercises by selectively supporting a dumbbell or part of a barbell is indicated by the numeral 100. In some embodiments a single one of the exercise weight support devices 100 may be employed to selectively support a barbell prior to, during and following the performance of a lifting exercise. However, in other embodiments, a pair of the exercise weight support devices 100 may be employed to each selectively support a separate one of a pair of dumbbells or to each selectively support one of two spaced-apart portions of the bar of a barbell. More specifically, FIG. 1 shows a partially exploded view of an embodiment of a single exercise weight support device 100 incorporating a belt 9, a retracting reel mechanism 26 coupled to a lower end of the belt 9, a trigger handle 19 to operate the retracting reel mechanism 26, and an outer frame 6 coupled to the retracting reel mechanism 26 to support a bar of a dumbbell or part of a bar of a barbell.

(10) The belt 9 may be formed from a length of relatively flat meshed webbing material similar to what may be employed in the making of seatbelts and/or tie-down straps for securing cargo, or any other suitable material for forming a belt with a tensile strength sufficient to support at least the weight of a dumbbell or part of the weight of a barbell. By way of example, at least a portion of the belt 9 may be made from one or more of woven polyester, nylon, polypropylene, Dyneema, Kevlar or other similar materials. The exercise weight support device 100 may be suspended by an upper end of the belt 9 from a ceiling or other overhead supporting structure, such as the metal framework of a cage or other structure of a piece of exercise equipment within a gym that is also capable of supporting the weight of a dumbbell or part of the weight of a barbell. An advantage of the use of the belt 9, with its relatively flat and wide cross-section, over a rope or cable of circular cross-section is the greater tendency for such a belt to resist twisting.

(11) The upper end of the belt 9 may be formed into a loop 8 to wrap around a carabiner 7 and/or other hardware (e.g., a steel S-hook) that may be attached to the upper end of the belt 9 and used to engage a beam or other structure of a ceiling, or of some other overhead supporting structure. Alternatively, the upper end of the belt 9 may be formed into a loop 8 to directly wrap around such a beam or other overhead supporting structure. Such formation of the loop 8 may be through stitching of the upper end of the belt 9 onto a lower portion of itself near the upper end. As another alternative, the upper end of the belt 9 may not be formed into a loop at all, leaving the upper end of the belt 9 free to be wrapped around, clamped to and/or tied to a portion of ceiling structure or other overhead supporting structure. Still other approaches to enabling the upper end of the belt 9 to engage a portion of a ceiling or other overhead supporting structure will occur to those skilled in the art.

(12) The lower end of the belt 9 may be wound around a spool 13 of the retracting reel mechanism 26 into which the belt 9 may be retracted and from which the belt 9 may be paid out to either shorten or lengthen, respectively, the portion of the belt 9 that extends upwards from the retracting reel mechanism 26 to a ceiling or other overhead supporting structure. The retracting mechanism 26 may include a torsion spring 20 housed within the core of the spool 13 and/or another component that tends to urge the spool 13 to rotate in a manner that retracts the belt 9 into the retracting reel mechanism 26, thereby tending to take up any slack in the belt 9 by tending to wrap more of the belt 9 around the spool 13. The amount of force applied by such a torsion spring or other component to take up slack in the belt 9 may be selected to balance out the weight of much of the exercise weight support device 100.

(13) The outer frame 6 may be formed from rigid steel tubing cut to define a support plate to which the retracting reel mechanism 26 may be attached and to define a pair of spaced-apart and substantially identically configured hooks 3 and 4. More broadly, it may be deemed desirable to make many of the components of the exercise weight support device 100 from steel, or from a lighter weight rigid material such as carbon fiber. As depicted, one or more mounting holes 28 may be formed through the support plate to enable the retracting reel mechanism 26 to be attached thereto with one or more sets of bolts 22 and nuts 23 to enable the weight of a dumbbell or part of the weight of a barbell carried by the outer frame 6 to be supported by the retracting reel mechanism 26. Alternatively, any of a variety of other mounting formations, including and not limited to slots, tabs, hooks, standoffs, keyholes, etc. may be formed in and/or otherwise incorporated into the support plate of the outer frame 6 to enable the retracting reel mechanism 26 to be attached thereto.

(14) The pair of hooks 3 and 4 may be spaced apart by a distance selected to be wide enough to allow a hand of a lifter to be inserted therebetween, but also narrow enough to allow the hooks 3 and 4 to fit between the weights of dumbbell as the bar of the dumbbell that extends between those weights is inserted into the interior spaces defined by each of the hooks 3 and 4. A cradle 5 may bridge between portions of the interior spaces defined by each of the hooks 3 and 4, and may form a curving trough within which such a bar of a dumbbell or a bar of a barbell may be seated upon being inserted into the interior areas defined by the hooks 3 and 4.

(15) Thus, with a single one of the exercise weight support devices 100 suspended by the upper end of the belt 9 from a ceiling or other overhead supporting structure, a single dumbbell may be suspended and supported therefrom by inserting the bar thereof into the interior spaces defined by the hooks 3 and 4, and seating it within the trough defined by the cradle 5. Alternatively, with a spaced apart pair of the exercise weight support devices 100 suspended by the upper ends of the belts 9 of each from a ceiling or other overhead supporting structure, a barbell may be suspended and supported therefrom by supporting each of two spaced apart portions of the bar thereof within a separate one of the pair of exercise weight support devices 100 in a similar manner.

(16) The trigger handle 19 may be movable between an engaged position in which the exercise weight support device 100 may be caused to support a dumbbell or part of a barbell, and a disengaged position in which exercise weight support device 100 may not provide such support. In the disengaged position, the trigger handle 19 is moved by a lifter into relatively close proximity to the bar of a dumbbell or a barbell that has been inserted into the interior areas defined by the hooks 3 and 4, and that has been seated within the trough defined by the cradle 5 (e.g., close enough to put the trigger handle 19 in contact with the bar or close enough that a finger tip cannot be inserted therebetween). In the engaged position, the trigger handle is allowed to be retracted from being in close proximity with the bar of such a dumbbell or barbell by one or more springs 14, 15 of the retracting reel mechanism 26 (e.g., retracted far enough away that a hand may be inserted between the trigger handle 19 and the bar).

(17) With the trigger handle 19 allowed by a lifter to be retracted to the engaged position by the one or more springs 14, 15, the retracting reel mechanism 26 is caused to become engaged in a manner that prevents any more of the belt 9 from being unwound and paid out from the reel 13. As a result, with the exercise weight support device 100 suspended from overhead by the upper end of the belt 9, allowing the trigger handle 19 to be retracted to the engaged position triggers the retracting reel mechanism 26 to prevent the exercise weight support device 100 from being pulled further downward and away from the upper end of the belt 9 by either a lifter or the weight of either a dumbbell or at least part of a barbell. Thus, with the trigger handle 19 allowed by a lifter to retract to the engaged position, a dumbbell or at least part of a barbell supported within the cradle 5 and the hooks 3 and 4 is able to be suspended by the exercise weight support device 100 from a ceiling or other overhead support structure to which the upper end of the belt 9 is attached. In this way, one of the exercise weight support devices 100 may be caused to suspend a dumbbell or part of a barbell from a ceiling or other overhead supporting structure at a desired height, such as an upper position of a lifting exercise.

(18) However, with the trigger handle 19 moved to the disengaged position against the force of the one or more springs 14, 15, the retracting reel mechanism 26 is caused to disengage to the extent of allowing the belt 9 to be both freely retracted to be wound about the spool 13 to take up slack in the belt 9 and freely unwound from the spool 13 and paid out. As a result, with the exercise weight support device 100 suspended from overhead by the upper end of the belt 9, moving the trigger handle 19 to the disengaged position triggers the retracting reel mechanism 26 to allow the exercise weight support device 100 to be either pulled further downward and away from the upper end of the belt 9, or to be lifted upward and toward the upper end of the belt 9 with the retracting reel mechanism 26 rewinding the belt 9 about the spool 13 to take up slack in the belt 9 as such upward lifting occurs. Thus, with the trigger handle 19 moved to the disengaged position, a dumbbell or at least part of a barbell supported within the cradle 5 and the hooks 3 and 4 is able to be freely raised or lowered by a lifter during the performance of a rep of a lifting exercise, with the belt 9 able to be freely retracted into or paid out from the retracting reel mechanism 26 as such raising and lowering for each rep occurs.

(19) Thus, by allowing the trigger handle 19 to remain in the engaged position while the exercise weight support device 100 is suspended from overhead by the upper end of the belt 9, the exercise weight support device 100 can be caused to support a dumbbell or a portion of a barbell at a suspended vertical height selected by a lifter until the lifter is ready to perform reps of a lifting exercise. The lifter may then trigger the reel mechanism 26 to disengage to the extent of allowing those reps to be performed without interference by moving the trigger handle 19 to the disengaged position against the force of the one or more springs 14, 15 as the lifter performs those reps.

(20) Upon completion of those reps or upon the lifter realizing that they are not able to continue performing those reps, the lifter need only let go of the trigger handle 19 to allow the trigger handle 19 to be retracted to the engaged position by the one or more springs 14, 15 to thereby cause the retracting reel mechanism 26 to once again become engaged to the extent of preventing the exercise weight support device 100 from being further pulled downward by the weight of the dumbbell or the weight of part of the barbell. In this way, both the lifting phase and the post-lift phase of a lifting exercise may be made considerably safer through the ability to cause the exercise weight support device 100 to selectively support the weight of a dumbbell or at least a portion of a barbell. There is no need for a lifter to drop dumbbells or a barbell in instances where the lifter realizes that they are not able to continue performing reps of a lifting exercise.

(21) The exercise weight support device 100 may also be used to make the pre-lift phase of a lifting exercise safer by reducing the exertion required of the lifter to prepare for the lifting phase, and by eliminating the need to perform coordinated maneuvers involving multiple limbs to get dumbbells or a barbell into position to begin the lifting phase. With the trigger handle 19 moved to the disengaged position against the force of the one or more springs 14, 15, each of a pair of the exercise weight support devices 100 may first be moved vertically to whatever height is desired as the starting point for a lifting exercise. Once at the desired height, the trigger handle 19 of each of the exercise weight support devices 100 may be allowed to return to the engaged position to cause each of the exercise weight support devices 100 to remain at that desired height. Then, either the bar of each of a pair of dumbbells or spaced apart portions of the bar of a single barbell may be inserted into the cradle 5 and the hooks 3 and 4 of each of the pair of the exercise weight support devices 100. As long as the trigger handle 19 is allowed to remain in the engaged position, the pair of dumbbells or the barbell remains suspended at the desired height, thereby allowing the lifter as much time as needed to position themselves as desired in preparation to begin their lifting exercise.

(22) Stated differently, as a result of the force exerted by the one or more springs 14, 15 to urge the trigger handle 19 towards the engaged position, the trigger handle 19 functions to some extent as a dead man's switch that serves to cause a cessation in at least a downward movement of a dumbbell or part of a barbell when the trigger handle 19 is not being continuously held in the disengaged position by a lifter. Thus, a lifter who comes to realize that they are unexpectedly unable to continue performing reps of a lifting exercise for whatever reason (e.g., a muscle spasm or over exertion, or a more serious event such as a heart attack) need only let go of the trigger handle 19 to allow it to move under the force of the one or more springs 14, 15 back to the engaged position. With the trigger handle 19 allowed to return to the engaged position, the retracting reel mechanism 26 is triggered to again engage to the extent of at least preventing a dumbbell or at least a portion of a barbell from falling either onto the floor or onto the lifter.

(23) In some embodiments, the retracting reel mechanism 26 may be a self-contained retracting ratchet mechanism of the type often used with tie-down straps for securing cargo for vehicle transport. An example of such a retracting ratchet mechanism is disclosed in U.S. Pat. No. 7,503,736 issued to Chen, the disclosure of which is incorporated herein by reference in its entirety. As depicted in FIG. 1, such an implementation of the retracting reel mechanism 26 may include its own inner frame 10 that may be bolted to the outer frame 6 by one or more sets of the bolt 22 and the nut 23 extending through the one or more mounting holes 28 of the outer frame 6 and one or more mounting holes 21 (not visible) of the inner frame 10. In such an implementation of the retracting reel mechanism 26, the reel 13 may be coupled on each end to one of a pair of ratchet wheels 11 and 12 that are engaged by a ratchet pawl 17, which may be coupled to opposite ends of the trigger handle 19 by handle portions 16 and 18. Together, the ratchet pawl 17, the handle portions 16 and 18, and the trigger handle 19 form a handle assembly 27. The handle portions 16 and 18 may cooperate with corresponding ones of a pair of channels 24 and 25 formed in portions of the inner frame 10 to guide the ratchet pawl 17 in a sliding motion into and out of engagement with the ratchet teeth of the ratchet wheels 11 and 12. Such a sliding motion may be controlled by movement of the trigger handle 19 between the engaged position in which the ratchet pawl 17 is moved into engagement with the ratchet teeth of the ratchet wheels 11 and 12, and the disengaged position in which the ratchet pawl 17 is moved out of engagement with the ratchet teeth of the ratchet wheels 11 and 12.

(24) In embodiments in which the retracting reel mechanism 26 is a retracting ratchet mechanism, the ratchet wheels 11 and 12 may be oriented to cause their ratchet teeth to interact with the ratchet pawl 17 in a manner that rotation of the spool 13 to unwind and pay out more of the belt 9 while the ratchet pawl 17 is moved into engagement with the ratchet teeth of the ratchet wheels 11 and 12 is prevented. However, movement of the spool 13 in the opposite direction to retract and wind more of the belt 9 onto the spool 13 while the ratchet pawl 17 is moved into engagement with the ratchet teeth of the ratchet wheels 11 and 12 may be permitted. Thus, the retracting reel mechanism 26 may allow the belt 9 to be retracted to take up slack in the belt as the exercise weight support device 100 is lifted with the trigger handle allowed to be retracted by the one or more springs 14, 15 into the engaged position.

(25) In alternate embodiments, the retracting reel mechanism 26 may include a simpler brake mechanism in combination with the spool 13 urged into retracting the belt 9 by the torsion spring 20 in lieu of a retracting ratchet mechanism. In such embodiments, allowing the trigger handle 19 to be retracted by the one or more springs 14, 15 into the engaged position may trigger the engagement of the brake mechanism to prevent either retraction of the belt 9 into or paying out of the belt from the retracting reel mechanism 26.

(26) As has been described, the trigger handle 19 may be moved in a sliding motion between the engaged position in which the trigger handle is allowed to be retracted by the one or more springs 14, 15 away from the bar of a dumbbell or part of the bar of a barbell, and the disengaged position in which the trigger handle is pulled against the one or more springs 14, 15 into relatively close proximity to such a bar. FIGS. 2A and 2B are each a cross-sectional view of a portion of the exercise weight support device 100 taken through a portion of each of the cradle 5, the support plate of the outer frame 6, the trigger handle 19, and either a bar of a barbell 31 or a bar of a dumbbell 29 or 30. From the perspective provided by both FIGS. 2A and 2B, an elevational view of the hook 3 of the outer frame 6 and of the handle portion 16 of the handle assembly 27 can be clearly seen, as well as an example of one possible pathway of sliding motion for the trigger handle 19 to follow between engaged and disengaged positions, as indicated with arrows.

(27) Also, as can be appreciated from a comparison between FIGS. 2A and 2B, the cross-section of the trigger handle 19 may differ in different embodiments. It may be that one or the other of these depicted cross-sections for the trigger handle 19, or one or more other cross-sections not depicted for the trigger handle 19, may be selected based on such factors as the diameter or cross-section of the bar of the barbell 31 or of the dumbbell 29 or 30. Also, regardless of what cross-section may be selected for the trigger handle 19, it may be deemed desirable for the selected cross-section to incorporate rounded edges to avoid instances of pinching portions of the skin of a hand therebetween.

(28) Further, as can be appreciated from the perspective of both FIGS. 2A and 2B, the cradle 5 and the trigger handle 19 may be sized and shaped to enable the inner surfaces of the palm and fingers of a hand to wrap around all three of the cradle 5, the trigger handle 19, and the bar of either a barbell 31 or of a dumbbell 29 or 30. As can also be seen from this perspective, the cradle 5 may be given a cross-section that defines a concave surface that faces and closely follows part of the circular cross-section of the bar, and defines a corresponding convex surface that substantially mimics the that same part of the circular cross-section of that bar. As a result, an exertion of upward force against at least the combination of the cradle 5 and the bar of either a barbell 31 or of a dumbbell 29 or 30 is likely to be directed against the convex surface defined by the depicted cross-section of the cradle 5. The fact that the convex surface of the cradle 5 does substantially mimic part of the circular cross-section of the bar, may desirably result in the use of the combination of the exercise weight support device 100 and either the barbell 31 or the dumbbell 29 or 30 feeling little different to a lifter than lifting only the barbell 31 or the dumbbell 29 or 30.

(29) With a palm and fingers of a hand of a lifter wrapped around at least the combination of the cradle 5 and the bar of a barbell 31 or of a dumbbell 29 or 30, a combination of gravity and the grip of the lifter's own hand may cooperate to maintain the bar within the interior areas defined by the hooks 3 and 4, and as seated within the trough defined by the cradle 5. Also, where the trigger handle 19 is moved into contact with the bar, the bar may be sandwiched between the trigger handle 19 and the cradle 5, thereby aiding in maintaining the bar within the interior areas defined by the hooks 3 and 4, and as seated within the trough defined by the cradle 5.

(30) However, FIGS. 2A and 2B also depict an edge-on view of a sheet 40 of hook-and-loop fastening material with hooks on one side and loops on the other such that hooks one side of the sheet 40 of hook-and-loop fastening material are able to engage and maintain a hold on the loops on the other side. The sheet 40 may be sized to be wide enough to cover the full length of the cradle 5, and also to be long enough to wrap around the combination of the cradle 5 and the bar of a barbell 31 or of a dumbbell 29 or 30. Thus, after the bar has been inserted into the interior areas defined by the hooks 3 and 4, and after the bar has been seated within the trough defined by the cradle 5, the sheet 40 of hook-and-loop fasteners may be wrapped around the combination of the bar and the cradle 5 to assist in keep the bar seated within the cradle 5.

(31) FIG. 3 depicts a cross-section of a portion of the exercise weight support device 100 from the same perspective as FIGS. 2A and 2B. As an alternative to the earlier discussed sliding motion of the trigger handle 19 depicted in FIGS. 2A and 2B, FIG. 3 depicts an alternate swinging movement of the trigger handle 19 between engaged and disengaged positions. In the disengaged position, the trigger handle 19 is swung by a lifter into relatively close proximity to the bar of a barbell 31 or of a dumbbell 29 or 30 that has been inserted into the interior areas defined by the hooks 3 and 4, and that has been seated within the trough defined by the cradle 5 (e.g., close enough to put the trigger handle 19 in contact with the bar or close enough that a finger tip cannot be inserted therebetween). In the engaged position, the trigger handle is allowed to be retracted in a swinging action away from being in close proximity with the bar of such a dumbbell or barbell by one or more springs (not shown) of the retracting reel mechanism 26 (e.g., retracted far enough away that a hand may be inserted between the trigger handle 19 and the bar).

(32) FIG. 4 depicts an example performance of a flat bench dumbbell press exercise that employs a pair of the exercise weight support devices 100, labeled as exercise weight support devices 100a and 100b to distinguish between them. As depicted, the exercise weight support device 100a, which incorporates one or more of carabiner 7a, attached to belt 9a via a loop 8a, and a cradle 5a, is employed to selectively support dumbbell 29. Correspondingly, the exercise weight support device 100b, which incorporates one or more of carabiner 7b, attached to belt 9b via a loop 8b, and a cradle 5b, is employed to selectively support dumbbell 30. The exercise weight support devices 100a and 100b may be of identical design such that they may be interchanged with each other, the dumbbells 29 and 30 may be swapped between them, and the components of each may be interchanged.

(33) FIG. 5 depicts an example performance of a flat bench barbell press exercise (also commonly referred to as a bench press) that also employs a pair of the exercise weight support devices 100, that again may be of identical design, and are again labeled as exercise weight support devices 100a and 100b to distinguish between them. As depicted, the exercise weight support device 100a, which incorporates one or more of carabiner 7a, attached to belt 9a via a loop 8a, and a cradle 5a, is employed to selectively support a left end 32 of barbell 31. Correspondingly, the exercise weight support device 100b, which incorporates one or more of carabiner 7b, attached to belt 9b via a loop 8b, and a cradle 5b, is employed to selectively support a right end 33 of the barbell 31.

(34) FIGS. 6A and 6B, together, depict two different parts of a rep of an example performance of a standard squat exercise (also commonly referred to as a squat) that again employs a pair of the exercise weight support devices 100 of identical design, and are again labeled as exercise weight support devices 100a and 100b to distinguish between them. As depicted, the exercise weight support devices 100a and 100b are again employed to selectively support the left end 32 and right end 33, respectively, of barbell 31. FIG. 6A depicts a part of the standard squat in which the barbell 31 lifted to an upper position, and FIG. 6B depicts a part of the standard squat in which the barbell 31 is lowered to a lower position.

(35) FIG. 7 depicts a block diagram of an embodiment of the exercise weight support device 100 that incorporates some degree of automation to increase convenience and/or ease of use. As depicted, such additional components may be in addition to at least a subset of the various components of the exercise weight support device 100 that have already been discussed above, including and not limited to, the frame 6, the hooks 3 and 4, the cradle 5, retracting reel mechanism 26, the spool 13, the belt 9 and the trigger handle 19. Additional components beyond what has been discussed above may be mounted to, carried by and/or otherwise incorporated into the frame 6, including and not limited to, one or more of a controller 150, a power source 105, a height sensor 110, manually-operable controls 120, a motor 170, a display 180, and a network interface 190. The controller 150 may incorporate a processor circuit 155, and a storage 160 storing one or both of a control routine 140 and lifter data 130. Also, the retracting reel mechanism 26 may additionally incorporate a transmission 175 to enable the spool 13 to be controlled by operation of the trigger handle 19, as has been described earlier, by operation of the motor 170, or by both.

(36) The control routine 140 may include a sequence of instructions to implement logic to perform one or more functions. The processor circuit 155 is coupled to the storage 160 and may access the control routine 140 within the storage 160 to execute the control routine 140, thereby causing the processor circuit 155 to perform one or more of those various functions. The processor circuit 155 may be any of a variety of commercially available processors, employing any of a variety of processing technologies and implemented with one or more cores physically and electrically combined in any of a number of ways. The storage 160 may be made up of one or more distinct storage devices that each may be based on any of a wide variety of storage technologies of volatile and/or non-volatile nature.

(37) More specifically, in executing the control routine 140, the processor circuit 155 may be caused to operate the controls 120 and/or the display 180 (if either or both are present) to provide a user interface to a lifter engaged in weightlifting. The controls 120 may be made up of any of a variety of switches, buttons, keypads, touch-sensitive surfaces and/or other components that enable the lifter to provide input. The display 180 may made up of one or more distinct components that are able to visually present information, ranging from one or more light-emitting diodes (LEDs) to a dot-matrix liquid-crystal display (LCD). Alternatively or additionally, in executing the control routine 140, the processor circuit 155 may be caused to operate the network interface 190 to interact with a smartphone, tablet computer or other device that may be operated by the lifter as an alternate approach to providing the lifter a user interface.

(38) Among the purposes for which such a user interface may be provided, either directly through the controls 120 and/or the display 180, or indirectly through the network interface 190 interacting with another device, may be to allow the lifter to turn the controller 150 on or off, or to provide the controller 150 with any of a variety of commands or other information pertinent to performing those commands. By way of example, as part of preparing to perform a lifting exercise, the lifter may desire to have the exercise weight support device 100 either retract or pay out some of the belt 9 to adjust the height of the at which the exercise weight support device 100 may currently be supporting a barbell, a dumbbell or another form of free weight. It may be that the lifter operates the controls 120 to command the processor circuit 155 to operate the motor 170 to drive the spool 13 through the transmission 175 to retract or pay out the belt 9 to thereby raise or lower the exercise weight support device 100. In some embodiments, the command may be a simple raise or lower command that the lifter may operate the controls 120 to continue to provide until the desired height is achieved. In some embodiments, the command may specify a particular measured height from a floor. In some embodiments, the command may include the identity of the lifter and an indication of the particular lifting exercise that is about to be performed.

(39) Where the command specifies a particular height from the floor, the processor circuit 155 may operate the height sensor 140 to determine the current height of the exercise weight support device 100 from the floor, and may then operate the motor 170 to cause retraction or paying out of the belt 9 to change the height of the exercise weight support device 100 until the specified height is reached. The height sensor 140 may be based on any of a variety of technologies for measuring the distance to a floor, including and not limited to emitting ultrasound pulses and determining how long an reflection of those pulses take to return, etc. Where the command specifies the identity of the lifter and includes an indication of the lifting exercise to be performed, the processor circuit 155 may access indications of the preferred starting heights of the lifter for various exercises to retrieve an indication of what height to either raise or lower the exercise weight support device 100 to by use of the motor 170.

(40) Given the possibility of data errors, processing errors, loss of power from the power source 105 and/or other forms of malfunction that may befall automated systems such as the controller 150, the transmission 175 may be configured to ensure that operation of the trigger handle 19, as has been described above, is never compromised by an action taken by the processor circuit 155, and/or is always able to override an action taken by the processor circuit 155. Correspondingly, the transmission 175 may also be configured to ensure that the operation of the trigger handle 19, as has been described above, is never dependent upon the power source 105 being able to provide electric power to the controller or upon the controller 150 functioning correctly. Indeed, it may be deemed desirable for the embodiment of the exercise weight support device 100 depicted in FIG. 7 to be operable entirely by the trigger handle 19, as has been described above, as if the controller 150 and the motor 170 were not present. Thus, the transmission 175 may incorporate either components of a ratchet mechanism (e.g., a ratchet wheel) or components of a brake mechanism that may be operable solely through movement of the trigger handle 19 between the engaged and disengaged positions.

(41) Although the invention has been described in a preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example, and that numerous changes in the details of construction and the manner of manufacture may be resorted to without departing from the spirit and scope of the invention. It is intended to protect whatever features of patentable novelty exist in the invention disclosed.
