- Referring now to the drawings a multi-purpose hand tool which is particularly, but not exclusively, suitable for use as a multi-purpose spanner comprises a
handle member 10 having a bifurcatedend portion 12. Aholding member 14 is pivotally mounted between the arms of the bifurcatedend portion 12 for pivotal movement in a plane containing the longitudinal axis of thehandle member 10. - The
holding member 14 comprises a central substantially cylindrical portion having a series ofteeth 16 formed on the periphery thereof and male inter- connecting means 18 of square shape in cross-section extending radially from the pivotal axis of theholding member 14. - The
handle member 10 is provided with a longitudinally extendingcentral bore 20 in which alocking member 22 is slidably mounted. The end of thelocking member 22 adjacent to theholding member 14 hasteeth 24 formed thereon which are adapted to engage in mesh with theteeth 16 on the central portion of theholding member 14 so as to retain the holding member in pivotally adjusted position. The spacing of theteeth - The end of the
locking member 22 remote from theholding member 14 has an enlargeddiameter end portion 26 formed thereon and acompression spring 28 is confined endwise between the enlarged diameter end portion of thelocking member 22 and the end face of an enlarged diameter portion of thebore 20 so that thelocking.member 22 is urged by thespring 28 to a position in which theteeth 24 thereon are disengaged from theteeth 16 on the holding member which is thus free to be moved pivotally. - A
cam carrier 30 is slidably mounted in the end of thebore 20 remote from theholding member 14 and a longitudinally extendingslot 32 is formed therein which is adapted to receive arectangular projection 34 extending from theend portion 26 of thelocking member 22. - An
operating arm 36 is mounted in theslot 32 and extends through afurther slot 38 formed in thehandle member 10 and extends therefrom towards the end of thehandle member 10 having theholding member 14 mounted therein. Theoperating arm 36 is arranged to be a close fit in theslot 38 and therectangular projection 34 is also arranged to be a close fit in theslot 32 of thecam carrier 30 thus restricting rotational movement of thelocking member 22 relatively to the handle member about the longitudinal axis of the handle member. - The
operating arm 36 is also provided with acam surface 40 which is adapted to engage in contact with the end face of theprojection 34 so that pivotal movement of the operating arm from the position shown in broken lines to the position shown in full lines in Figure 1 of the drawings urges thelocking member 22 against the action of thespring 28 into a position in which theteeth 24 engage in mesh with theteeth 16 of theholding member 14 to retain theholding member 14 in pivotally adjusted position. An externally screw- threadedend cap 42 is mounted in an internal screw- threadedend portion 44 of thebore 20 of thehandle member 10 and theend cap 42 is arranged to engage in contact with thecam carrier 30 so as to adjust the position thereof along the longitudinal axis of thebore 20. This adjustment of the pivotal position of theoperating arm 36 enables adjustment to be made to the force exerted by theteeth 24 when they engage in mesh with theteeth 16 on theholding member 14 in order to inter alia compensate for any wear which may take place. - A
locking member 46 is slidably mounted on the external surface of thehandle member 10 and is provided with acam surface 48 which is adapted to engage in frictional wedging contact with thecam surface 50 formed on the free end of theoperating arm 36 to retain the operating arm in the engaged position shown in full lines in Figure 1 of the drawings. Theoperating arm 36 is released by slidably moving thelocking member 46 on the external surface of thehandle member 10 towards theholding member 14 so as to disengage the interengagingcam surfaces spring 28 to the disengaged position shown in broken lines in Figure 1 of the drawings. The locking member is provided with a conventional spring loadedball arrangement 52 which is adapted to engage incomplementary recesses 54 in the external surface of thehandle member 10 when the locking member is in either its engaged or disengaged position. Agroove 56 extends between therecesses 54 and the spring loadedball 52 is arranged to engage therein during movement of thelocking member 46 between the disengaged and engaged positions so as to restrain thelocking member 46 against rotational movement relatively to thehandle member 10 about the longitudinal axis thereof. - Referring now Figs. 5, 6, 7 and 8 of the drawings a
fastener engaging member 60 is provided with a conventional openended spanner 62 at one end thereof and arecess 64 at the opposite end thereof which forms a female interconnecting means which is capable of interconnection with the male interconnecting means 18 on theholding member 14. Therecess 64 is arranged to be a multi-sided polygon whose sides are an exact multiple of the sides of the male interconnecting means 18 and in this particular case, therecess 64 is arranged to be a substantially sixteen sided polygon so that the square male interconnecting means 18 can be inserted therein in a plurality of positions which enable the angular position of the openended spanner 62 to be adjusted relatively to theholding member 14 and thehandle member 10 in increments of forty five degrees to improve the versatility of the tool. - Referring now particularly to Figures 12, 13 and 14 af the drawings, a locking insert indicated generally at 80 is formed of a compressible plastics material and comprises a
flange 82 having four equiangularly spaced-apart ribs 82 extending therefrom. The ends of theribs 84 remote from theflange 82 are connected together by anend plate 86 having acentral aperture 88 formed therein which increases the flexibility of thelocking insert 80. - The
locking insert 80 is adapted to be inserted into therecess 64 of thefastener engaging member 60 and when the square male interconnecting means 18 is inserted into thelocking insert 80 disposed in therecess 64, theribs 84 are compressed. This compression produces a retaining action in the form of a frictional force restricting movement between thefastener engaging member 60 and the interconnecting means 18 of theholding member 14. - The
locking insert 80 is capable of being inserted into therecess 64 in a plurality of positions so as to enable the position of thefastener engaging member 60 to be adjusted relatively to theholding member 14 as previously described. - It will also be appreciated that the
fastener engaging member 60 can take the form of not only various sizes of open ended spanner but also additional fastener engaging members can be provided having other types of fastener engaging means thereon such as ring spanners, socket heads, Allen keys, screw driver heads or indeed any other suitable form of arrangement without departing from the scope of this invention. - Referring now specifically to Figures 9 to 11 of the drawings, a
knuckle adapter 70 consists of a male interconnecting means 72 disposed at one end thereof and a female interconnecting means 72 disposed at the opposite end thereof. The male interconnecting means 72 is disposed at an angle to the female interconnecting means 74 and a whole series of knuckle adapters may be used in which the male and female interconnecting means thereon are disposed at different angles. The male interconnecting means 72 conforms to the interconnecting means 18 on theholding member 14 and the female interconnecting means 74 conform to therecess 64 on thefastener engaging member 60. Theknuckle adapter 70 is arranged to be mounted on the male interconnecting means 18 of theholding member 14 and the fastenerengaging member 60 is mounted on the male interconnecting means 72 so that the knuckle adapter is disposed between theholding member 14 and thefastener engaging member 60. It will be appreciated that the utilisation of such knuckle adapters increases the versatility of the tool as it enables the fastener engaging members to be disposed at an increased number of angles to thehandle member 10 of the tool. It will be appreciated that thelocking insert 80 is also used in conjunction with theknuckle adapter 70 as previously described. - A conventional spring-loaded
ball mechanism 76 is also provided on the male interconnecting means 18 of theholding member 14 to enable fastener engaging members which are provided with a female interconnecting means in the form of a recess having a conventional square shape in cross-section to be releasably retained on theholding member 14, of the type used, for example, in conventional socket equipment. - In operation, when the
operating arm 36 is in the position shown in broken lines in Figure 1 of the drawings, the angle of thefastener engaging members 60 to thehandle member 10 of the tool is adjusted to a convenient position and theoperating arm 36 is then moved to the position shown in full lines in Figure 1 of the drawings by an operative gripping thehandle member 10 and theoperating arm 36 in one hand. The tool is dimensioned so that it is possible for the thumb of an operative to then slide thelocking member 46 into the engaged position so that theholding member 14 is retained in adjusted position relatively to thehandle member 10. It will also be appreciated that during use of the tool, the greater the force exerted by an operative on the tool, the greater the force exerted upon theoperating arm 36 by the grip of the operative and the greater the engaging force exerted between theteeth 24 and theteeth 16. This arrangement ensures that theholding member 14 is firmly and positively retained in adjusted position relatively to thehandle 10 when a large force is exerted upon the tool by an operative.
