Abstract

A handgrip in the form of a tube of resilient material has internal lugs 32-37 shaped and spaced apart to fit within recesses in a tang to prevent rotation of, or withdrawal of, the hand grip relative to the tang and to form air cushions between the hand grip and tang. <IMAGE>

Description

SPECIFICATION A handle, in particular for a hand-tool This invention relates to a handle, in particular for a hand-tool such as a pair of garden shears, but applicable to other implements such as a tennis racquet.

According to one aspect of the present invention there is provided a handle comprising a tang and a hand grip which has been fitted by longitudinal sliding movement on to the tang, the hand grip being in the form of a tube of resilient material, the tube being closed at its rearward end, and being formed on its inner surface with a plurality of lugs spaced apart axially and circumferentially of the tube, the tang having recesses therein for engage ment by the lugs to prevent rotation and rearward movement of the hand grip relative to the tang.

According to another aspect of the present invention there is provided a handle comprising a tang shaped to provide a plurality of recesses therein and a resilient hand grip which surrounds the tang and traps air in the said recesses.

A handle in accordance with the invention, and in particular for use in a pair of garden shears, will now be described by way of example only with reference to the accompanying drawings in which Figure lisa plan view of a handle of a pair of garden shears; Figure 2 is an enlarged view of part of the handle of Fig. 1, with part of the hand grip cut away; Figure 3 is a side elevation of the handle of Fig. 1, part sectioned on the line Ill-Ill of Fig. 2, and Figure 4 is a section on the line IV-IV of Fig. 3.

As shown in the drawings, the handle 10 comprises a tang 11 and a hand grip 12, the hand grip being in the form of a tube of resilient material, closed at its rearward end which has been fitted on to the tang by longitudinal sliding movement.

The tang, as seen in Figs. 2,3 and 4, is a casting or moulding, in particular of metal, of skeleton configuration formed by three relatively flat and parallel-spaced longitudinally-extending ribs 13, 14, 15 interconnected by centrally-located longitudinally-extending connecting ribs 16, 17 and transverse ribs such as 20,21,22,23 at the inner end of the handle or such as 24, 25, 26 as seen adjacent the rearward end of the handle. The inner end of the tang at 27 has a smooth external surface which is stepped downwardly at 28 to form a shoulder against which the inner end of the hand grip abuts, the downwardly-stepped portion 30 forming a seat for the tubular end of the hand grip. At its rearward end the tang is formed with a solid boss 31.

The skeleton shape of the tang will thus be seen to form a plurality of recesses, and the inner surface of the hand grip is formed with a plurality of lugs such as 32, 33,34,35, 36,37 which are shaped to be received in the recesses of the tang.

Since the hand grip is designed to be slid on to the tang, each of the lugs is formed with a rearwardly inclined or swept back forward face to facilitate the movement of the hand grip over the ribs of the tang.

Similarly, the rearward faces of the lugs are abruptly formed to engage against the forward faces of the ribs and prevent rearward movement of the hand grip after it has been fully fitted on to the tang, with its leading edge pressed firmly against the shoulder 28.

It will be seen that the recesses of the tang are spaced apart both circumferentially and longitudinally so that once the hand grip has been fitted on to the tang, the inter-engagement of the lugs with the recesses of the tang will prevent both rotational movement of the hand grip on the tang and longitudinal rearward movement of the hand grip.

The lugs do not extend to the bottom of the recesses of the tang into they engage, and since the hand grip will fit tightly around the ribs, a plurality of air pockets are formed between the lugs and the bases of the recesses in which air is trapped.

Accordingly, the hand grip will have a resilience greater than the resilience of the material of which it is made by virtue of the air cushion formed by each of the air pockets. It will be evident that these air pockets can be shaped and located as may be required to give a desired greater or less resilience in selected parts of the handle.

The external surface of the hand grip can have a roughened texture over a major part of its surface and can be formed with ribs, where engaged by the thumb of the user, to give additional grip.

Although it is conventional in garden shears to provide handles which are straight (since it is normal to insert a straight tang into a straight bored cylindrical hole in the handle) the present construction enables curved handles to be provided on the hand tool as indicated by Fig. 1. These will preferably be oppositely curved, ie concave towards each other, in the plane of movement of the handles.

1. A handle comprising a tang and a hand grip which has been fitted by longitudinal sliding movement on to the tang, the hand grip being in the form of a tube of resilient material, the tube being closed at its rearward end, and being formed on its inner surface with a plurality of lugs spaced apart axially and circumferentially of the tube, the tang having recesses therein for engagement by the lugs to prevent rotation and rearward movement of the hand grip relative to the tang.

2. A handle according to Claim 1 wherein each lug has a leading surface which is swept back and facilitates fitting of the grip by sliding movement on to the tang.

3. A handle according to Claim 1 or Claim 2 wherein each of at least some of the lugs has a trailing surface which is substantially normal to the longitudinal axis of the hand grip and resists removal of the hand grip from the tang.

4. A handle comprising a tang shaped to provide a plurality of recesses therein and a resilient hand grip which surrounds the tang and traps air in the
