The present invention relates to a handle for a tool.
More specifically, in accordance with the present invention, there is provided an assembly, comprising a handle, a tool head and a sleeve, wherein an end of the handle engages within the sleeve on a first end of the sleeve and the sleeve engages within a socket of the hand tool on a second end of the sleeve, the sleeve thereby securely connecting the handle and the tool hand.
There is further provided a method, comprising providing a handle, providing a sleeve, providing an implement head comprising a socket, inserting the handle, from an end thereof, within the sleeve by a first end of the sleeve, and inserting the sleeve, by a second end thereof, within the socket of the implement head.
Other objects, advantages and features of the present invention will become more apparent upon reading of the following non-restrictive description of specific embodiments thereof, given by way of example only with reference to the accompanying drawings.
In the appended drawings:
The present invention is illustrated by the following non-limiting examples.
As shown for example in
Typically, the tool head 14 comprises a tool body 18, such as the scoop of a shovel as illustrated herein for example, and a socket 20 for connection with the handle 12.
In
The socket 20 may have a tubular shape of a generally constant diameter; or the socket 20 may have a conical shape, i.e. as a tube with a decreasing diameter from an open end 21 thereof to its connection to the too head 14, as illustrated in
In case of a hollow handle 12, an insert 23, in a composite material, steel, wood or plastic for example, may be inserted to extend within the handle 12 and the socket 20 for supporting the assembly of the handle 12 with the socket 20 and connecting the handle 12 with the socket 20, from the inside of the handle 12 and of the socket 20 as shown in
As shown in an embodiment illustrated in
The handle 12 is thus inserted within the sleeve 16 into a press-fit engagement at least along a distance, i. e. with at least a length thereof covered by the sleeve 16 within the socket 20. In
Instead of a shoulder (JS), the sleeve 16 may have a length of continuously decreasing diameter followed by a length of constant diameter for example. Still alternatively, the sleeve 16 may have a constant diameter all over a length thereof, a longitudinal slot 17 ending at its end 26, as shown in
As shown in
Rivets 28 may be used to further secure the assembly together (see
As illustrated in
Thus the sleeve 16 may have a constant or a decreasing diameter, it may comprise a shoulder or be deprived thereof, it may comprise a longitudinal slot 17, so as to adjust between the handle and the socket.
Embodiments of the sleeve 16 are shown in
As shown in
As shown for example in
The handle 12 may be a hardwood handle or a composite such as in glass fibers for example. The sleeve may be in a metal such as iron, in a plastic or a composite material, or engineering plastic for example.
Depending on the tool head, the tool may be a shovel, a spade, a fork, a shingle remover, a pry bar, a nail puller, a loglifter, a log roller etc. . . .
Load tests were performed on different tools comprising a handle connected to a tool head by inserting the free end if the handle within the socket of the tool head and riveting as known in the art, each one characterized by its weight, and with an implement comprising an assembly of a handle and a tool head as described herein, by hanging an increasing load to the handle of the tools maintained generally horizontal by the tool head thereof (see
The scope of the claims should not be limited by the embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
