Golf bag having elongated tubular body and shoulder strap assembly comprising first and second straps, each having first and second ends; and bridge member having first and second ends and being disposed undetachably between second end of first strap and second end of second strap; the elongated tubular body configured to be detachably adjoined to first end of first strap, first end of second strap, second end of first strap, and second end of second strap. Strap may have a first section, second section and third section that are configured to be adjacent the wearer's front, shoulder, and back, respectively; third section has curve with upper portion extending vertically with respect to wearer and lower portion extending horizontally with respect to wearer. A concave radius r.sub.cc can extend from strap first end to approximate the second end; wherein r.sub.cc>a convex radius r.sub.cv at the strap second end.

Embodiments of the invention provide a series of tensioning straps that are applied to the trampoline frame under tension. The tensioning straps serve to stiffen the trampoline frame which improves performance. The tensioning straps may be improved via the application of various sideways straps as well. The tensioning straps and the sideways straps may reside in channels or loops on the trampoline edge pad in order to further secure the edge pad in place.

A self-powered vibration mechanism is provided that can be mounted on an existing pedal shaft yet operates independent from the existing pedal. Mechanical isolation or mechanical decoupling permits transferring the vibrating energy to the foot rather than to the pedal shaft and the bicycle. In another embodiment, a full removable pedal with self-powered vibration mechanism can replace an existing pedal.

Disclosed herein is a golf club head that comprises a body. The body comprises a sole portion, a crown portion, a skirt portion, and a face portion, positioned at a forward region of the golf club head, opposite a rearward region of the golf club head, and extending from a toe region to a heel region of the golf club head. At least a portion of the body is made of a titanium alloy. The golf club head also comprises a large weight, coupled to the sole portion of the body and made of a steel alloy. A mass of the large weight is at least 40% of a mass of the portion of the body made of the titanium alloy. A total mass of the large weight and the portion of the body made of the titanium alloy is at least 210 grams.

A 3-Dimensional golf game having a horizontal surface, a vertical surface, and a curvilinear surface that interconnects the horizontal and vertical surfaces, wherein at least the vertical surface includes one or more ball-receiving cups. The game of skill is played by one or more players putting or striking a golf ball along the horizontal surface with sufficient force to travel through the curvilinear surface and up the vertical surface. The force of gravity then causes the ball to return back down the vertical surface and—if appropriately aimed and struck—the ball travels downwardly into the opening of the least one ball receiving cup. Players are awarded points for successfully landing the ball into the ball receiving cup and the game may include differently sized and/or positioned cups having different point values.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y) and maintaining a consistently and relatively low CG location measured along a direction tangent to the hosel axis along the X-Y plane (CG-B).

Disclosed herein is a casting cluster for casting a body of a golf club head made of titanium or a titanium alloy. The casting cluster comprises a receptor and a plurality of runners coupled to the receptor and configured to receive molten metal from the receptor. The casting cluster also includes at least forty main gates. At least two of the main gates are coupled to each of the runners and each main gate is configured to receive molten metal from a corresponding one of the plurality of runners. The casting cluster further comprises at least forty molds. Each mold of the at least forty molds is configured to receive molten metal from a corresponding one of the main gates and to cast a body of an iron-type golf club head.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A protective non-helmeted single molded facemask for sports includes a frame structure formed of a polycarbonate polymer that is structured and configured to engage a user's forehead, side and cheek facial structure and chin. An arrangement of vertical and horizontal bars in the central and lower portion of the face area of the facemask protect the users nose and mouth from direct contact with external objects, and particularly softballs, soccer balls, floor hockey sticks and pucks and field hockey sticks and balls. Upper and lower straps extend from slotted openings on the sides of the facemask and are positioned and arranged to extend around the lower back of the wearer's head to secure the facemask on the wearer's head. The facemask is designed to also significantly reduce the effective impact forces to the wearer's brain.

Disclosed herein is a spring ring device having a unique ability to bounce and rebound off hard surfaces while maintaining a continued flight path, acting as if it had just been thrown back to the thrower after ricocheting off a wall. The spring ring device will bounce off one or multiple surfaces and can be caught by the same or a different player. The spring ring device generally includes a ring, a ring cover configured to encase the ring. The spring ring device may also include a shell configured to cover at least a portion of the ring cover. The unique structure of the spring ring device allows the device to bounce and rebound off hard surfaces and maintain a continued flight path.
