| 101 | Handle assembly for relieving wrist joint stress | US909306 | 1992-07-06 | US5275068A | 1994-01-04 | Robert A. Wrench |
| The handle assembly comprises a beam which extends from an area on the user's forearm to just beyond the user's knuckles between the phalanges and metatarsals. A saddle at the forearm end distributes loads over the forearm area. The saddle may be fitted with a adjustable strap to hold the saddle in place. There is a journal at the knuckle end, the axis of the journal being essentially parallel to the beam and positioned such that the hub of a hand grip attached to a shaft in the journal fits between the fore and middle fingers of the users hand. An adaptor is attached to the shaft to facilitate attaching any of a variety of tools or implements to the assembly. In one embodiment of the invention the grip comprises a second saddle which engages the wrist joint for the hand. Mounting the grip and adaptor on the journalled shaft enables altering the active direction of the tool or implement without moving the forearm saddle on the arm. | ||||||
| 102 | Composite handle for tools | US779312 | 1991-10-18 | US5211669A | 1993-05-18 | David R. Bonnes; Charles A. Seifert |
| An implement handle includes an axially elongated core member having a varying cross-sectional outer dimension, and an outer polymeric shell having axially-oriented substantially-continuous strength members, the outer shell enclosing and being bonded to the core and of substantially uniform thickness. The handle may include a wood core and a bendable portion integral with the shell, the bendable portion being adapted to fit within a handle socket of a tool. | ||||||
| 103 | Auxiliary tool handle | US200451 | 1988-05-31 | US4930181A | 1990-06-05 | Samuel V. Johnson |
| An auxiliary tool handle for attachment to cylindrical tool handles, such as those used for garden rakes, hoes, push brooms and the like. The auxiliary tool handle comprises at least one curvilinear handle segment for removable and adjustable mounting on a conventional tool handle. Sleeves for slidable mounting of the handle segments on conventional cylindrical tool handles are attached to the handle segments, thereby enabling adjustable mounting thereof about the circumference and along the length of the tool handle. | ||||||
| 104 | Accurate lightweight manual lawn and garden weed chipper | US119266 | 1987-11-09 | US4886125A | 1989-12-12 | Hugh M. Reilly |
| An improved accurate lightweight manual tool to cut suburban lawn and garden weeds efficiently and with little time and effort expended. It is like a miniature hoe half a man's height in length with a very thin very narrow blade, in length four to five times its width (FIG. 5). The chipper's light weight is achieved with a very lightweight conduit handle of any section joined at right angles by a secret joint to a backing plate for the blade and weighted with billet to increase and change the power for weight. A thin shock absorber is bolted between plate and blade by.The secret joint uses a steel billet driven through the metal plate into the conduit handle thereby expanding the handle against the metal collar and plate which has a self-centering protrusion fitting into a recess in the collar. The permanent right angle secret locking joint uses totally prefinished components. | ||||||
| 105 | Crumb shovel | US71932 | 1987-07-10 | US4767141A | 1988-08-30 | Arthur T. Martin |
| A crumb shovel used to remove excess spoil, gravel, or soil from within any depth trench, cave-in, or the like. The crumb shovel has an elongated handle, a circular scoop, and is designed to be operated by one person. The scoop may provide a spring-loaded, knockout dumping system, such that when the spring is released the dumping system would push out the contents of the scoop. The handle is available with two options. The handle may have an arm with a lever to actuate the dumping system, or it may have either an adjustable or a fixed rear arm, or both. | ||||||
| 106 | Tool product and method of making | US651072 | 1984-09-17 | US4718708A | 1988-01-12 | Victor Zacuto |
| A hand tool, such as a shovel, having unique working head or blade and shank elements. The blade includes a dished panel transversely disposed from its longitudinal axis and flaring from rear to working end. The trough of the blade is shallower at its distal or working end than at its rear end at which the shank is secured such as by welding. The shank is of a single-walled tubular construction and includes a cut, pinched, angled end which is welded to the rear of the blade, a buckled, curved portion extending from such securement to a straight portion integrally continuing from such buckled and curved portion, to an expanded hub swedged contiguous to the other end of the shank. A tapered handle fits to and through such hub, secured by a rivet to the shank. A plane of symmetry extends throughout the tool. The invention includes method for forming tool, blade, and shank. | ||||||
| 107 | Raised grip shovel | US941534 | 1986-12-10 | US4690447A | 1987-09-01 | Michael Adams |
| A raised grip shovel has the handlebar with the back grip at one end and a front grip being raised to a level of the back grip during a shovel operation. Such elevation of the front grip can be achieved by curvilinear shape of the handlebar or by various support elements. A front grip position can be adjusted in accordance with a person's particular height, arm length and physical conditions. The angular and spacial relocation of the front grip straightens the posture and increases the digging thrust. The change of the posture alleviates the back stress by shifting the load to the legs and lower back muscles which are significantly stronger than muscles of the upper body. | ||||||
| 108 | Auxiliary shovel handle | US818192 | 1986-01-13 | US4615553A | 1986-10-07 | Donald W. Hultine |
| An auxiliary handle for attachment to the primary handle of a conventional shovel includes upper and lower handle portions which are connected together for length adjustable sliding movement relative to one another. Coacting stops on the upper and lower handle portions limit the extent of relative sliding movement therebetween. A biasing mechanism urges the upper handle portion downwardly toward the retracted position thereof. Furthermore, the range of extendible lengths for the auxiliary handle may be adjusted to accommodate different users. | ||||||
| 109 | Flexible core for tool handles | US407819 | 1982-08-13 | US4451073A | 1984-05-29 | Joseph A. Carmien |
| A flexible core is provided for insertion in the handle receiving socket of a tool blade, such as a shovel. This flexible core provides compressive support inside the handle socket to prevent buckling or collapse of the socket when the socket is subjected to high bending stress. | ||||||
| 110 | Handle accessory for work tools | US892650 | 1978-04-03 | US4155582A | 1979-05-22 | Robert J. Reisner |
| A lightweight handle accessory particularly adapted to be mounted on the generally straight shaft of a work tool or other working or sporting implements, having a clamping portion partially surrounding the shaft or other surface to be gripped which cooperates with a flexible fastening means of variable diameter to frictionally engage the shaft and fixedly mount the handle accessory. A handle is mounted near the outward end of opposing lever arms to enable the operator to grip the assembly. The underside of the gripping portion is serrated and divided into mirror images with a central slot which allows flexing of the gripping portion to adapt to a wide variety of mounting surface sizes and tapers. The flexible fastening means may be easily disengaged from one shaft or implement and remounted on another differently sized shaft or implement without loss of holding power. | ||||||
| 111 | Shovel | US816297 | 1977-07-18 | US4129327A | 1978-12-12 | Claud T. Moore, Jr. |
| A new and improved shovel including a shovel blade connected at one end to a main handle member and having an opposite, open end for initially engaging the ground to scoop up dirt or the like and an auxiliary handle assembly attached to the shovel blade at the opposite, open end and extending adjacent to, but independent of, the main handle member for cooperating with the main handle member to lift and maneuver a load of dirt or the like. | ||||||
