Abstract
A composite tool handle includes a first body (14) made of steel alloy, a second body (12) made of carbon fiber or glass fiber coated on the outer periphery of the first body, and a third body (16) made of carbon fiber or glass fiber coated on the periphery of the second body.
Description
2 The present invention relates to a composite tool handle.
3 A conventional tool handle in accordance with the prior art is made 4 of a steel alloy that is heavy, thereby causing inconvenience to a user when rotating the tool handle to adjust a workpiece. In addition, the conventional tool handle is electrically conductive such that the user is easily susceptible to 7 shock when the workpiece contacts an electrical source, thereby injuring the 8 user or damaging the work piece. Further, the conventional tool handle with 9 little elasticity easily produces vibration when the user holds the tool handle to to rotate it to adjust the workpiece, thereby decreasing the stability of the tool 11 handle. The present invention has arisen to mitigate and/or obviate the 12 disadvantages of the conventional tool handle.
13 In accordance with one aspect of the present invention, a composite 14 tool handle comprises a first body made of steel alloy having an outer periphery, and a second body made of carbon fiber or glass fiber attached to the 16 outer periphery of the first body.
17 The composite tool handle further comprises a third body made of 18 carbon fiber or glass fiber coated on the periphery of the second body.
19 Further benefits and advantages of the present invention will become 2o apparent after a careful reading of the detailed description with appropriate 21 reference to the accompanying drawings.
22 In the drawings:
23 Fig. 1 is a side plan view in partial section of a composite tool handle 24 in accordance with the present invention;
1 Fig. 2 is a partial perspective view in partial section of the composite 2 tool handle in Fig. 1;
3 Fig. 3 is a side plan view in partial section of a composite tool handle 4 in accordance with another embodiment of the present invention;
Fig. 4 is a side plan view in partial section of a composite tool handle 6 in accordance with a further embodiment of the present invention;
7 Fig. 5 is a partial perspective view in partial section of the composite 8 tool handle in Fig. 4;
9 Fig. 6 is a top plan view in partial section of a composite tool handle in accordance with a further embodiment of the present invention;
11 Fig. 7 is a partial perspective view in partial section of the composite 12 tool handle in Fig. 6;
13 Fig. 8 is a top plan view in partial section of a composite tool handle 14 in accordance with a further embodiment of the present invention;
Fig. 9 is a side plan view in partial section of a composite tool handle 16 in accordance with a further embodiment of the present invention; and 17 Fig. 10 is a partial side plan view in partial section of a composite 18 tool handle in accordance with a further embodiment of the present invention.
19 Referring to the drawings and initially to Figs. 1 and 2, a composite 2o tool handle in accordance with the present invention is adapted to suit an 21 adjustable wrench ( 10), and comprises a first body ( 14) made of steel alloy, and 22 a second body ( 12) made of carbon fiber or glass fiber attached to the outer 23 periphery of the first body ( 14). The first body ( 14) is formed with two j aws 24 (140) in opposition to each other to adjust a workpiece (not shown).
1 In such a manner, the second body ( I 2) made of carbon fiber that is 2 light greatly decreases the weight of the composite tool handle, thereby 3 decreasing the cost of fabrication, and thereby facilitating a user operating the 4 composite tool handle. In addition, the second body ( 12) made of carbon fiber with great strength and rigidity can efficiently increase the vibration absorbing 6 effect of the tool handle when the user holds the tool handle to rotate it to adjust 7 the workpiece, thereby increasing the stability of the tool handle. Further, the 8 composite tool handle with the second body ( 12) has a great corrosion resistant 9 and acid resistant capacity.
Alternatively, the second body ( 12) made of glass fiber can be used 11 to increase the aesthetic quality of the tool handle.
12 Further, the second body ( 12) made of carbon fiber or glass fiber will 13 prevent a user from being shocked by an electric current due to its insulating 14 property, thereby assuring the user's safety when holding the tool handle.
Referring to Fig. 3, in accordance with another embodiment of the 16 present invention, the first body ( 14) longitudinally extends into the middle of 17 the second body ( I 2).
18 Referring to Figs. 4 and 5, in accordance with a further embodiment 19 of the present invention, the composite tool handle is adapted to suit a pair of pliers ( 1 OA).
21 Referring to Figs. 6 and 7, in accordance with a further embodiment 22 of the present invention, the composite tool handle is adapted to suit a closed 23 end wrench ( 1 OB).
1 Referring to Fig. 8, in accordance with a further embodiment of the 2 present invention, the composite tool handle further comprises a third body ( 16) 3 made of carbon fiber or glass fiber coated on the periphery of the second body 4 ( 12).
13 In accordance with one aspect of the present invention, a composite 14 tool handle comprises a first body made of steel alloy having an outer periphery, and a second body made of carbon fiber or glass fiber attached to the 16 outer periphery of the first body.
17 The composite tool handle further comprises a third body made of 18 carbon fiber or glass fiber coated on the periphery of the second body.
19 Further benefits and advantages of the present invention will become 2o apparent after a careful reading of the detailed description with appropriate 21 reference to the accompanying drawings.
