| 85 | MULTIFUNCTIONAL DIGGING TOOL | US14431392 | 2013-09-16 | US20150366122A1 | 2015-12-24 | Enrique VERA ANDRADES |
| The invention relates to a dual-function tool, i.e. having two interchangeable tools, one providing a shovel function and the other providing a fork function, both suitable for digging the ground. For this purpose, the tool comprises a shaft (1) with one end provided with a cross-piece to form a cross-handle, and the other end provided with means for mounting a digging tool (3-3′), such as a shovel or fork, such that the corresponding shaft (1) comprises at least two sections (1′-1″) which can be removably screwed to one another, the cross-piece of the upper handle comprising a T-shaped connector (5) which can be removably coupled on the upper end of the shaft, and two side elements (7) which can be screwed onto the end of each of the side arms of the T-shaped connector, together forming an upper cross-piece having an oversized length. The interchangeable tool is mounted on the lower end of the shaft (1). | ||||||
| 86 | Ergonomic garden tool handle | US14468433 | 2014-08-26 | US09149925B1 | 2015-10-06 | Stephen Van Valin |
| An ergonomic tool handle is designed for “one-handed” use by incorporating a hand grip and a forearm support in a compact arrangement. The tool handle includes a longitudinal shaft with a vertical hand grip formed at one end and a forearm support at the opposing end. The hand grip is essentially U-shaped and oriented such that the “U” is upside-down and attached to the longitudinal shaft at two separate locations (the “top” ends of each leg of the “U”). The forearm support takes the form of an enlarged support area (with respect to the diameter of the shaft) and in one embodiment is V-shaped (with a cross-member attached between the legs of the “V”). Preferably, various tool implements may be removably attached to the longitudinal shaft of the handle (e.g., screw-on, locking pin, etc.). | ||||||

| An attachment device detachably connects a gardening or cultivating tool to the blade of a garden hoe. This attachment device enables a tool such as weed cutters, rakes, pronged tools, and scythes to be detachably mounted to a hoe. The attachment device includes a sheet of metal wherein one or more U-shaped slots are formed along one edge. Tool retaining bolts are threaded into threaded holes in one side of the U-shaped slot(s) to tightly engage the hoe blade within the slot. A cutting tool having this attachment device maintains a spring loaded cutting blade which floats with respect to the hoe attachment device so that compression of the springs during use stores energy when the cutting blade hits an object for enhancing the cutting cycle and for reducing operator fatigue. | ||||||

| A coupling device for connecting a handle part and a tool part includes a plug and a socket. The plug has a main portion, an end portion, and a notched portion between the main portion and the end portion. The socket has a proximal base end, a body portion, and a locking member. The body portion extends from the base end and has an axial, plug receiving bore that opens through a distal end of the body portion. The locking member is positioned between the base end and the plug receiving bore. The locking member includes a leaf spring cantilevered axially on one side of the body portion of the socket. The leaf spring supports a latch bar that engages the notched portion of the plug when the plug is inserted through the open end of the plug receiving bore. The latch bar is spaced from the leaf spring so that the end portion of the plug passes between the latch bar and the leaf spring when the plug is inserted through the open end of the plug receiving bore. The latch bar is released from the notched portion of the plug when the leaf spring is depressed inwardly from the one side of the socket body. | ||||||

| A new hand tool with interchangeable attachments for providing a gardener with several tools while requiring a single handle. The inventive device includes a handle portion having a dowel extending therethrough upwardly of a lower end thereof. The dowel has diametrically opposed end portions extending outwardly of the handle portion. A shank portion couples with the handle portion. The shank portion has a recess extending within an upper end thereof. The recess is dimensioned for receiving the lower end of the handle portion therein. The upper end has a pair of diametrically opposed vertical slots extending downwardly thereof in communication with the recess. The vertical slots slidably receive the opposed end portions of the dowel of the handle portion. A collar member is slidably disposed on the handle portion. The collar member has an externally threaded open upper end and an outwardly flared open lower end. The open lower end has a pair of diametrically opposed recesses extending upwardly thereof. The recesses receive the opposed outer ends of the dowel therein when in a fully engaged orientation. | ||||||

| Each gardening tool proper (1) has a hollow mounting end-piece (3) provided on its free edge with a hook-shaped or channel-shaped member (4a,4b) whose opening is directed towards the working end of the tool. A handle (2) of either wood or plastic has a diameter at the lower end thereof which permits engagement with slight friction within the end-piece (3). A tool-retaining device stationarily fixed near the lower end of the handle has a resilient loop (11) which is intended to be engaged within the hook-shaped or channel-shaped member (4a,4a) of the end-piece. After engagement, the loop can be stretched or slackened (by means 5and 7 to 10) in order to permit either rigid interassembly or subsequent separation of tool proper and handle. | ||||||
| 98 | Ground working implement assembly | US732450 | 1985-05-09 | US4606089A | 1986-08-19 | Garry L. King |

Each implement head has a ground working member (13A, 14A, 15A, 16A and 17A) and a tang (13B, 14B, 15B, 16B and 17B). One end of the handle (11) has a socket assembly (20) adapted to receive the tang of an implement head. A retaining pin (31) removably secures the tang of an implement to the socket assembly (20) when the tang is received thereby. The implement heads (13, 14, 15, 16 and 17) are configured so that they are nestable with each other for storage. | ||||||

| The specification discloses a tool used for chopping and scraping earth which is easily convertible into numerous different implements such as a rake, shovel, broom, fork or the like. An apertured working section is disposed normally to an elongated handle. Two intersecting planar cutting surfaces are integrally formed and extend along the base of the working section in order to define a cutting edge which enables the tool to be used for cutting soil. The aperture formed through the working section permits the passage of earth therethrough to facilitate scraping of soil. The working section contains several smaller apertures to which any of a variety of attachments can be bolted when it is desirable to use the tool for some function other than chopping or scraping earth. | ||||||
