JP2001260040A - Tool with two pivoted jaws opened and closed - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a tool with two pivoted jaws opened and closed that can ensure a reliable opening/closing operation with firmly gripped handle portions even when they have oil adhesion. SOLUTION: Handle portions 2 of a pair of arms 1a and 1b coupled in a openable and closeable manner are covered in covers 8 of synthetic resin. Each cover 8 has staple 9 secured by flocking to the outer surface. Even when the covers 8 have oil adhesion, the staple 9 prevents the slip of the hand giving the handle portions 2 an opening and closing operation and thus ensures a reliable opening and closing operation of the handle portions 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing tool such as pliers, nippers, pliers and the like.

[0002]

2. Description of the Related Art A connecting portion is provided at the tip of a handle, and two arms provided with a chin at the connecting portion are connected at the connecting portion so as to be openable and closable. In the pliers provided with the portions, the handle portion of each arm is covered with a cover made of a synthetic resin in order to easily grip the handle portion and to enhance the design value of the pliers.

[0003] In addition to the above-mentioned pliers, radio pliers and nippers are designed to cover the handle.

[0004]

In the case of an opening / closing tool having a cover, such as a pair of pliers or nippers, if the hand gripping the cover or the handle gets greasy, it slips and cannot be firmly gripped. There is a disadvantage that the opening and closing operation of the unit becomes difficult and the workability is reduced.

Further, in the opening / closing tool, when the pair of handles are closed, the gap formed between the ends on the opening / closing center side of the handles is small. When the grip part comes off the pin, the pair of handle parts closes, and the fingers are sandwiched between the end faces of the pair of handle parts on the opening and closing center side,
Risk of serious injury.

An object of the present invention is to provide a cover-equipped opening / closing tool capable of firmly gripping a pair of handles even when oil adheres.

[0007]

According to the present invention, there is provided an opening / closing tool comprising a pair of openable and closable handles each covered with a synthetic resin cover. In this case, a short fiber is fixed to the surface of the sheet by flocking.

As described above, by fixing the short fibers to the outer surface of the cover, even if oil adheres to the hand gripping the cover or the handle, the short fibers prevent the hand from slipping. Therefore, the handle can be firmly grasped and tightened, and the opening and closing operation of the handle can be reliably performed.

Here, if one of the opposing surfaces at the ends of the pair of covers on the arm opening / closing center side is provided with a plurality of cushioning protrusions made of elastic fins, the opening / closing center side of the pair of handle portions is provided. Even if the finger is pinched at the end, the protrusion is elastically deformed to buffer the impact on the finger, so that it is possible to prevent the finger from being seriously injured.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows pliers as an opening and closing tool. The pliers are composed of two arms 1a, 1b. Each of the arms 1a and 1b has a joint 3 at the tip of the handle 2 and a jaw 4 at the joint 3.

The arms 1a and 1b are combined so that the joints 3 overlap with each other, and can be opened and closed about a pin 5 connecting the joints 3 with each other. A blade 7 is provided.

A cover 8 is provided on the handle 2 of each of the arms 1a and 1b.
Is covered. The cover 8 is made of a synthetic resin such as polypropylene, and short fibers 9 are fixed to the outer surface of the cover over substantially the entire length by flocking.

Further, of the pair of covers 8, one of the covers 8 is provided with an elastic shock-absorbing protruding portion 10 at the end on the inner side of the arm opening and closing center. The protruding portion 10 has a configuration in which a plurality of elastic fins 11 extending in the width direction of the inner surface of the cover 8 are provided at intervals in the length direction of the cover 8.

As described above, by fixing the short fibers 9 to the outer surface of the cover 8 covering the handle 2, the short fibers 9 exhibit the effect of preventing slipping, and the cover 8 and the handle Even if oil adheres to the hand holding the handle 2, the handle 2 can be firmly gripped and the handle 2 can be reliably opened and closed.

Therefore, the work of cutting a wire such as an electric wire with the blade portion 7 and the work of adding a pin or the like with the holding portion 6 can be performed efficiently, and the workability can be improved.

Also, the elastic projections 10 for cushioning are provided on the inner surface of the end of the cover 8 at the center of the arm opening and closing, so that when the pair of holding portions 6 are pulled out while holding the pins, etc. The grip 6 comes off and the handle 2 closes,
Even if a finger is sandwiched between the ends of the handle 2 on the opening / closing center side, the protruding portion 10 is elastically deformed and absorbs the impact on the finger, so that it is possible to prevent the finger from being seriously injured.

In the embodiment, the pliers are shown as the open / close tool. However, the open / close tool is not limited to this, and may be, for example, radio pliers, nippers, or pliers.

[0018]

As described above, in the opening and closing tool according to the present invention, the short fibers are fixed to the outer surface of the cover over the handle of the arm, so that oil adheres to the hand gripping the cover and the handle. Even when the short fibers prevent hand slippage, the pair of handle portions can be reliably opened and closed.

Further, by fixing the short fibers, the design value of the open / close tool can be enhanced.

Further, by providing an elastic projection on the inner surface of the end of one of the covers on the arm opening / closing center side,
Even if a finger is pinched at the end of the pair of handle parts on the opening / closing center side, the impact on the finger can be absorbed by the elastic deformation of the protrusion, preventing the finger from being seriously injured. it can.
