Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention particularly relates to hand tools having a metal outer surface coated with one or more composite materials.

[0002]

[Prior art and its problems]

 Hand tools are frequently used in everyday life and include, for example, spanners, adjustable wrenches, and box wrenches, all of which are formed directly from a metal material. The tools have the following problems. 1. Since the specific gravity of iron of a metal tool is 7.8, a user is burdened when using it, and it is difficult to work. 2. Since the iron handle is easily rusted, the handle is very poor. 3. The materials used in conventional hand tools are very brittle, have poor elasticity, and are heavy, making it impossible to control the vibration transmitted to the hands and elbows during repeated operations. Therefore, the hands and elbows and their joints may be adversely affected. 4. Since a metal hand tool has conductivity, when a handle is gripped, moisture such as sweat is easily generated on a user's hand. Therefore, there is a risk of electric shock.

As described above, conventional hand tools are very heavy and inefficient in work, so it is necessary to develop hand tools that are more convenient and practical.

[0004] The present invention solves the above-mentioned problems, and includes one or more coatings made of a base material and a composite material, the coatings being provided so as to cover the outer periphery of the base material except for a portion of the base material that comes into contact with a workpiece. By forming the tool from the body, it is possible to reduce the weight of the tool and at the same time to strengthen it and to provide a more excellent insulating effect.

[0005]

[Means for Solving the Problems]

 The present invention provides a hand-held tool comprising a substrate 14 and one or more coatings 12 made of a composite material and provided so as to cover the outer periphery of the substrate 14 except for a portion of the substrate 14 which comes into contact with a workpiece. .

[0006]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 10, the hand-held tool 10 according to the present invention is composed of a base 14 and a composite material, and covers the outer periphery of the base 14 except for a portion of the base 14 that comes into contact with a workpiece. The base 14 has excellent hardness and considerable strength because it comprises one or more coatings 12 provided as described above. In addition, since other parts, such as those without a handle part code, are made of a light composite material, the weight of the entire tool can be significantly reduced.

A hand tool 10 shown in FIGS. 1 and 2 is a free wrench, and has a cover 12 and a base 14 made of a metal material such as an alloy. The base 14 is formed at one end of the hand tool 10. An active jaw 142 and a fixed jaw 141 are provided at a position in direct contact with the object, and clamp the workpiece on the base 14. The active jaw 142 includes a metal adjusting member 16 provided at the lower end thereof. While being activated by rotating, a T-shaped convex portion 15 is formed on both outer sides of the active jaw 142 and the fixed jaw 141 along the edge thereof, and the T-shaped convex portion 15 is fitted on the inside of the covering 12. You.

The cover 12 is formed by impregnating a carbon fiber material or a glass fiber material with a resin, and then heating and pressing to cure to form the handle portion 101 of the manual tool 10, and at the same time, The hand tool 10 is also formed by being coated on the outside and then being heated and hardened again. Further, an active jaw 142 and a fixed jaw 141 for clamping a workpiece on the base body 14 are formed, and the active jaw 142 is activated by rotating a metal adjustment member 16 provided at a lower end thereof. A T-shaped protrusion 15 is formed on the outer sides of the jaw 142 and the fixed jaw 141 along the respective edges, and the T-shaped protrusion 15 is fitted inside the cover 12, and the cover 12 and the base 14 The surface of the joint portion between and is formed flat without any steps.

As shown in FIG. 3, in another embodiment of the adjustable wrench, a fixed jaw 141 and an active jaw 142 are formed on one side of the base 14, respectively, and the other side extends toward the handle 101. A shaping portion 148 is formed, thereby fixing the base 14 in the covering 12.

The hand tool 10A shown in FIGS. 4 and 5 is a plier, which is made of a metal material and has jaws 144 and 145 formed on a base 14 which comes into contact with a workpiece, and is provided outside the jaws 144 and 145. A T-shaped convex portion 15 is formed along the edge, and the cover 12 is coated on the outside of the base 14, and the cover 12 is coated without a handle symbol.

The manual tool 10B shown in FIGS. 6 to 8 is a closed wrench. An annular box portion 17 is formed on a base 14 made of a metal material at both ends of the closed wrench. At the end, an extending portion 171 having a thickness smaller than that of the box portion 17 is provided, and the outer periphery of the extending portion 171 and the outer periphery of the box portion 17 are covered with the covering 12. At this time, the contour of the box 17 is exposed by making the thickness of the cover 12 and the box 17 equal.

Further, as shown in FIG. 8, the outer periphery of the cover 12 of the manual tool 10B is coated with a cover 121 of a different composite material in a single layer, and the cover 12 is made of, for example, carbon fiber material. The cover 121 is made of, for example, a glass fiber material.

A hand tool 10 C shown in FIG. 9 is a pair of pliers. The pliers have a head portion 102 and a handle portion 101 made of a cover 12, and two halves forming a base 14 on both sides inside the head portion 102, respectively. The jaws 146 and 147 are sandwiched, and the outer periphery of the handle 101 made of the covering 12 is covered with the covering 121 made of another composite material.

A hand tool 10D shown in FIG. 10 is a hammer, a hammer body is formed of a cover 12, and one end of the hand tool 10D is provided with no head code, and the head is formed of a base 14 made of a metal material. In addition, a through hole 143 for penetrating the covering 12 is formed at the center, and the covering 12 is penetrated through the through hole 143 to form a hammer body handle portion.

In addition, since a coating made of a composite material can be colored, a hand tool excellent in aesthetic appearance and texture can be provided, and a resin obtained by impregnating a carbon fiber material or a glass fiber material with a colorant is impregnated. Thereafter, if the coating is heated and cured, the surface of the coating layer can be colored. If you want to apply a variety of colors to the coating, you can form a colorful coating by alternately coating the coating with a composite material of a different color, heating and curing again. In addition, by printing characters or graphics directly on the surface of the cover, the appearance of the tool can be further improved.

[Effect of the invention]

 As described above, the specific gravity of the carbon fiber material in the present invention is about 1.4, and the glass fiber material is about 1.8, which is much lighter than the specific gravity of iron, 7.8. The burden on the user when gripping the part can be reduced, and the weight of the entire tool when carrying can be significantly reduced. Since the coating has excellent insulation properties, accidents such as electric shock can be prevented. The hand tool according to the present invention mainly comprises a cover, which has characteristics of excellent strength, rigidity and light weight, and is integrally joined to the base by a hot press. Since the position in contact with the metal material is exposed from the cover as it is the metal material, wear can be prevented and the strength of the tool can be greatly increased. The coating has acid and alkali resistance, corrosion resistance, and does not rust.Therefore, there is no danger of surface destruction, and it has excellent heat insulating properties and minimizes heat conduction even when working in a high temperature environment. It does not cause burns on the hands, and has excellent elasticity and can suppress vibrations to the hands during work, so that the hands can be felt when gripped. very good. The carbon fiber material or glass fiber material is impregnated with a resin containing a coloring agent to change the color, or color characters and figures can be printed on the surface of the coating, so various patterns can be formed on the surface of the tool. It can be done.
