DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(14) For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings, which are described below. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. The invention includes any alterations and further modifications in the illustrated devices and described methods and further applications of the principles of the invention, which would normally occur to one skilled in the art to which the invention relates.

(15) Referring now to FIGS. 1-8, one embodiment of a self-spotting bench press mechanism and system is shown generally indicted as 10. A standard bench 12 is shown, which can be used with self-spotting bench press mechanism and system 10 is, and a user or lifter 14 is shown in broken lines in FIGS. 1 and 1A, lying on bench 12 and lifting a barbell with weights 16. It should be appreciated that bench 12 and barbell and weights 16 are well known in the art and a variety of readily available units can be utilized with self-spotting bench press mechanism and system 10. Alternately, bench 12 may be provided as part of self-spotting bench press mechanism and system 10. In the embodiment shown, bench 12 includes four legs 18, a frame 20 supported by legs 18, 18a, a user support 22, and a pair of weight supports 24, located at an end of bench 12 where user 14's head is located when using bench 12. Bench 12 also includes a leg leverage support 26, which in the embodiment shown is attached to one of legs 18 using fasteners or other known means of attachment. The use of leg leverage support will be described in further detail below.

(16) Self-spotting bench press mechanism and system 10 also includes a bottom support or frame, generally indicated as 30, an upright support, generally indicated as 32, an extension support arm 34, a pulley and cable system, generally indicated as 36, and a foot pedal 38. In the embodiment shown, bottom frame 30 has a generally C shaped configuration and is preferably manufactured from a suitably strong material, such as but not limited to, steel or aluminum as is also suitable for all of the structural members of self-spotting bench press mechanism and system 10. Bottom frame 30 includes a longitudinal member 40 and two cross members 42, 44. Members 40, 42, and 44 may be attached by welding or using suitable fasteners and can be made from circular or square tubing or angled members for instance, as is also suitable for all of the structural members of self-spotting bench press mechanism and system 10. Stiffeners 46 are attached in the joining areas of members 40, 42, and 44 to provided added strength and stability to the assembly.

(17) Upright support 32 is attached to and extends upward and perpendicular from cross support member 44 and is attached using a suitable joining method such as by welding. Extension support arm 34 is attached to the opposite end of upright support 32 by welding or other suitable means and extends perpendicular thereto and parallel to longitudinal member 40. Stiffeners 48 can be used to enhance the rigidity and strength of this connection.

(18) In the embodiment shown, foot pedal 38 is mounted to a swing arm 50 using fasteners or other suitable attachment means. Swing arm 50 is in turn, pivotally attached and connected to cross member 42 using a hinged connection 52. This allows the foot pedal to swing outward from bench 12 to reduce the effective weight of weights 16 as will be described in further detail below. Also, in the embodiment shown, a cable guide 54 is mounted to cross member 42 extending upward and in front of swing arm 50. Cable guide 54 includes through holes 56 for receipt of a cable and may include a sleeve to facilitate smooth sliding of the cable therein.

(19) Now referring to pulley and cable system 36, this assembly includes a steel or otherwise suitably strong cable 60, at least three pulleys 62, and a tensioning weight 64. Two of the pulleys are pivotally connected to extension support arm 34 and the other pulley 62 is pivotally connected to upright support 32 towards a lower end thereof. One end of cable 60 is connected to the barbell of weights 16 with a loop or eye hook 66, which can include a quick release latch as is well known. The opposite end of cable 60 is attached to swing arm 50. The rest of the cable is threaded around pulleys 62 as shown in the figures, threaded through an eyelet 68 attached to tensioning weight 64, and through holes 56 in cable guide 54.

(20) In operation, as should be appreciated tensioning weight 64 maintains tension on cable 60 through movement of the barbell of weights 16. Otherwise, the tension in cable 60 would change drastically from the weights 16 being supported on supports 24 and between when a user has their arms extended and bringing their arms down to do a bench press. It is important for tension to remain on the cable so that when a user needs assistance with lifting weights 16 back onto supports 24, the user 14, can push on foot pedal 38 thereby swinging swing arm 50 outward, which pulls on cable 60 and the end 66 connected to the barbell will assist in lifting the weight upward so that it can be placed safely on supports 24. It should further be appreciated that as user 14 extends their arms upward this effectively reduces the distance that cable 60 traverses, so that tensioning weight 64 sinks downward as the cable slides through eyelet 68. As user 14 lowers the dumbbell of weights 16 toward their chest, this increases the distance that cable 60 traverses so that tensioning weight rises and cable 60 slides on eyelet 68.

(21) Additionally, user 14 can use the calf of the leg not pushing on pedal 38 to push back against leg leverage support 26 to prevent the user 14 from sliding back on bench support 22 instead of pushing the pedal outward.

(22) Now referring to FIG. 9, an alternate embodiment pulley and cable system 136 is shown. Pulley and cable system 136, is the same in all respects as pulley and cable system 36, except that loop or eyehook 66 is not connected directly to the barbell of weights 16. Rather, it is connected to two short angled lengths of cable 160 to help offset imbalance as compared to a single cable slightly off center on the barbell. Cables 160 each include loops or eye hooks 166 on both ends thereof. One end is connected to loop 66 and the other end is connected to the barbell of weights 16.

(23) Now referring to FIG. 10, an alternate leg leverage support 126 is shown. Leg leverage support 126 is mounted to a support member 127 and extends above user support surface 22. Additionally, leg leverage support 126 is mounted at an angle. Raising and angling leg leverage support 126 can make it easier for user 14 to hook with their leg that is not pushing on pedal 38 to provide a better leverage position for user 14 to push out pedal 38, thereby swinging out swing arm 50 to assist in lifting weights 16 up and onto supports 24.

(24) While the invention has been taught with specific reference to these embodiments, one skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the invention. For instance, although the embodiment shown and described above utilizes an optic sensor, the system may be used with other types of sensors for sensing when a syrup transmission line is empty. Therefore, the described embodiments are to be considered in all respects only as illustrative and not restrictive. As such, the scope of the invention is indicated by the following claims rather than by the description.
