Abstract: A hand-operated tool lock mechanism secures a pair of grips in a closed locked state. The mechanism includes: a holding recess at the end of one grip; an engaging recess at the end of the other grip; a ring component removably and rotatably disposed in the holding recess, which engages with the engaging recess placing the grips in the closed state; and a catch for removably and rotatably inserting the ring component in the holding recess. The holding recess and the catch hold the ring component oriented away from the other grip when the ring component is disengaged from the engaging recess. When the hand-operated tool is used, the releasing of the ring component from the locked state causes the ring component to be held between the holding recess and the catch in an orientation in which the ring component does not contact the other grip.

Abstract: An electric trimming device (100) achieves mechanical advantages by use of a rotational assembly (600) creating an offset rotation used to move a movable blade (350) in a back and forth series of movements. Thus, traditional rotational movement from an electric motor is efficiently translated into a reciprocating scissor type movement. A moveable blade (350) defines a longitudinal void (360) the void used to retain a sliding pin (616) with a scissor blade bearing (618) rotating around the sliding pin. The sliding pin is attached to outer portions a radial rotational plate (610) with an inner portion of the plate attached to an axle of a motor. To achieve a smooth planar movement of the moveable blade the radial rotational plate spins in and out of a guide assembly (700).

Abstract: Various scissor embodiments feature channel voids or passages defined within the inside surfaces of scissor blades or shaft sections. The channel voids or passages allow foreign matter to be self-expelled by the movement of the scissor blades. Disclosed blades or shafts are pivotally connected by a new connection assembly that expels foreign matter during the normal use of the scissors. Disclosed embodiments include scissors comprising: a pair of blades (1A, 1B) overlapping each other; and a shaft (3) inserted through a shaft support hole (2) in the blades (1A, 1B) and having a tip (4) that is bucked to allow the blades (1A, 1B) to pivot in an abutting state, a passage communicating with the outside to allow inflow and outflow of water, etc. is formed between abutting faces (5) of both blades (1A, 1B) and between the shaft (3) and the shaft support holes (2).

Abstract: A wood-type golf club head is provided with a face having a double-wall construction. The use of a double-wall construction allows two different materials for the face, allowing the golf club head to be fabricated with many different weight distributions, impact sounds, different feel and different impact energy transfer characteristics. The inside face plate can be solid, or perforated with openings, provided with center ribs, or other weight distributing and strengthening features. The club head bottom, sides and the inner face can be fabricated as a unitary formed plate by a press forming process from a single sheet of a metal material. The inner face plate is bent to the desired loft, and the top plate, hosel pipe and outer plate are attached to the unitary structure by welding or other attachment techniques. Another club head has a lowered and forwardly positioned center of gravity.

Abstract: A method of fabricating a metal wood club head. The head is fabricated in two half-sections, each formed by a casting technique. Increased production throughput is achieved by the use of forming dies to maintain the shape of the two half-sections after removal from the casting molds, before the head half-section elements have fully hardened to a solid state. The two half-sections are subsequently joined by welding together facing edges of the respective half-sections along a parting line. The parting line extends through the highest point in the head crown, generally parallel to the face region and behind the hose. The placement of the parting line permits the use of simple one-piece mold cores, since there are no negative angles within the half-section elements to prevent such a core from being removed. The method is low cost, and provides a high strength club head, with the weld joint located away from club stress points.

Abstract: A golf driver club having a face which is smooth and free of grooves or other indentations at the ball-impacting surface. The club includes a hollow metal club body with the ball-impacting surface formed from a rigid, non-resilient metal. The ball-impacting surface is highly polished to obtain the smoothness. The golf driver club tends to result in drives wherein the ball does not spin, providing improved accuracy and drive distance.

Abstract: A hollow wood-type golf club is fabricated with a thin layer of elastomeric dampening material coating the inner surface region opposite the ball impacting face and within the hollow cavity of the head shell. The layer provides vibration dampening, improving the play of the club. A low cost, simple method to fabricate the head with the layer includes dispensing a quantity of uncured elastomer in liquid form into the cavity, maintaining the head with the inner surface opposite the ball impacting face at a horizontal attitude to cause the liquid to pool over this inner surface region, and curing the elastomer with the head in this attitude until the elastomer has cured and hardened. Golf iron and putter clubs are described with a vibration dampener consisting of a thin layer of elastomer material adhered to a base cavity surface of a cavity backing the ball impacting surface. Methods for fabricating the iron and putter clubs are described.

Abstract: A hollow wood-type golf club is fabricated with a thin layer of elastomeric dampening material coating the inner hollow cavity of the head shell. The layer provides vibration dampening, improving the play of the club. The vibration dampening material can also be applied in a thickened region at a desired location within the cavity to achieve a desired weighting to affect the balance of the head. A low cost, simple method to fabricate the head with the layer includes dispensing a quantity of uncured elastomer in liquid form into the cavity, coating the inner surface, pouring off the excess material, optionally weighing the head and adding an amount of the liquid elastomer to bring the head up to a desired nominal weight, maintaining the head at an attitude to cause the excess liquid to pool at a location at which additional weight is desired, and oven curing the elastomer with the head in this attitude until the elastomer has cured and hardened.

Abstract: A metal wood golf club head with a hollow body shell of a first lightweight material and a sole plate of a second material having a higher specific weight density than the first material. The sole plate is attached to the shell without welding, fasteners or force-fitting. The center of gravity of the head is lowered, and other weight distributions can be achieved by alternate sole plate configurations, such as heel, toe or rear weighting. The head is fabricated by a process which includes the steps of providing the sole plate of the second material, disposing a core adjacent the interior surface of the sole plate, disposing an exterior mold about the core so that the exterior mold, the core and sole plate collectively define a mold cavity in the form of the body shell, filling the cavity with the second material in a fluid state, and permitting the second material to solidify. Upon solidification, the second material locks onto the sole plate, fixing the sole plate in position.

Abstract: An improved golf club wherein the surface of the face of the club is substantially flat, which is achieved by surfacing (milling) the club face, and wherein the edges of scoring lines (grooves) are made relatively sharp as a result of the surfacing operation. The sharp groove edges (and milling lines) of the present invention produce enhanced backspin and reduced sidespin when a golf ball is struck, which results in a relatively straight golf ball flight path, notwithstanding a glancing club impact angle. In addition, milling lines that may be formed on the club face are generally parallel to the scoring lines and hence enhance the club characteristics. The present invention also provides for methods of making a golf club that has the above features, including forging and casting methods. In either method, a club is processed to produce generally smooth and finished features with scoring lines formed in the face of the club.

Abstract: A golf club having a metal club head with a faceplate insert made of a high strength, lightweight metal material such as titanium. The weight savings resulting from the lighter, stronger titanium permits mass to be distributed to improve the moment of inertia of the club head. Both iron and metal wood clubs having the titanium faceplate insert are described.

Abstract: A golf bag with integrated support legs is disclosed. The legs are pivoted at the top of the bag, and may be extended to a stand position, forming a support stand for the golf bag to support the bag in an inclined position. A flexible rod extends longitudinally along a side of the bag between the legs, with a spring member extending between the bottom support of the bag and respective positions intermediate the leg ends. To cause the legs to be opened to the stand position from a upright position adjacent the bag body, a force is applied to the top of the flexible rod, causing it to flex and thereby pivot the legs outwardly to the stand position. When the bag is picked up the legs are automatically restored to the upright position.

Abstract: The specification herein discloses a golf club having an improved moment of inertia. The improved moment of inertia is for both a driver and a putter. The driver is formed of an investment casting having peripheral weights proximate the toe side and heel side of the club. A third weight is provided at the rear of the club. The weights provide a three dimensional configuration for weighting the club wherein the rear weight provides an increased moment of inertia. By increasing the moment of inertia, the club has a lesser tendency to twist when it strikes the ball off the center of gravity thereby creating less torque or twist to the club head for more accurate direction. The putter has the moment of inertia weighting applied above its midline center of gravity so that it provides overspin or top spin to the ball when struck.

Abstract: A perimeter weighted hollow golfing iron having a foam core with an effective hitting area concentrated toward the center of moments is disclosed. The weight of the club is concentrated at the perimeter to provide for the center of moments and proximate effective hitting area over the core. The club is formed from an investment casting having a cavity and is made from a method whereby the club is originally cast with a tapered core which is later withdrawn. Thereafter, an end plate is implaced over the cavity and welded thereto with an opening for insertion of the foam with an epoxy plug filling the opening of the plate. An effective hitting area is established by means of a club holder having a transducer so that impacts through an impact device against the club face can be sensed by the transducer to provide signals to an output such as a CRT, digital or analog readout or oscilloscope.

Abstract: A method for the manufacture of golf clubs of the iron or wood types having the characteristic of improved driving power. This characteristic of greater driving power results from the manufacture of the golf clubs with a flexible striking face. The flexible striking face is designed to vibrate in simple harmonic motion of the same frequency as the struck golf ball. The flexible striking face design is such that the frequency of vibration of the striking face is constant across its face and the amplitude of vibration is constant across its face and, as a consequence thereof, the restoring force of the resilient face combines with the restoring force of the struck golf ball to impart a greater distance to the drive. The method of manufacture comprises casting a head having a neck and body dependent thereon and providing the body with an open cavity behind its face that extends from one edge thereof across a substantial portion of the face.
